2233 Rearrangement and Depletion of Human Skin Folate after UVA Exposure
Authors: Luai Z. Hasoun, Steven W. Bailey, Kitti K. Outlaw, June E. Ayling
Abstract:
Human skin color is thought to have evolved to balance sufficient photochemical synthesis of vitamin D versus the need to protect not only DNA but also folate from degradation by ultraviolet light (UV). Although the risk of DNA damage and subsequent skin cancer is related to light skin color, the effect of UV on skin folate of any species is unknown. Here we show that UVA irradiation at 13 mW/cm2 for a total exposure of 187 J/cm2 (similar to a maximal daily equatorial dose) induced a significant loss of total folate in epidermis of ex vivo white skin. No loss was observed in black skin samples, or in the dermis of either color. Interestingly, while the concentration of 5 methyltetrahydrofolate (5-MTHF) fell in white epidermis, a concomitant increase of tetrahydrofolic acid was found, though not enough to maintain the total pool. These results demonstrate that UVA indeed not only decreases folate in skin, but also rearranges the pool components. This could be due in part to the reported increase of NADPH oxidase activity upon UV irradiation, which in turn depletes the NADPH needed for 5-MTHF biosynthesis by 5,10-methylenetetrahydrofolate reductase. The increased tetrahydrofolic acid might further support production of the nucleotide bases needed for DNA repair. However, total folate was lost at a rate that could, with strong or continuous enough exposure to ultraviolet radiation, substantially deplete light colored skin locally, and also put pressure on total body stores for individuals with low intake of folate.Keywords: depletion, folate, human skin, ultraviolet

Authors: Qiang Wang, Hongyang Yu
Abstract:
Multi-human 3D pose estimation is a challenging task in computer vision, which aims to recover the 3D joint locations of multiple people from multi-view images. In contrast to traditional methods, which typically only use color (RGB) images as input, our approach utilizes both color and depth (D) information contained in RGB-D images. We also employ a transformer-based model as the backbone of our approach, which is able to capture long-range dependencies and has been shown to perform well on various sequence modeling tasks. Our method is trained and tested on the Carnegie Mellon University (CMU) Panoptic dataset, which contains a diverse set of indoor and outdoor scenes with multiple people in varying poses and clothing. We evaluate the performance of our model on the standard 3D pose estimation metrics of mean per-joint position error (MPJPE). Our results show that the transformer-based approach outperforms traditional methods and achieves competitive results on the CMU Panoptic dataset. We also perform an ablation study to understand the impact of different design choices on the overall performance of the model. In summary, our work demonstrates the effectiveness of using a transformer-based approach with RGB-D images for multi-human 3D pose estimation and has potential applications in real-world scenarios such as human-computer interaction, robotics, and augmented reality.Keywords: multi-human 3D pose estimation, RGB-D images, transformer, 3D joint locations

Authors: Shailendra Kumar Singh
Abstract:
In the 21st century, we are living through extraordinary times as we are linguistically blessed to live through an era in which the each sociolinguistic example of living appears to be refreshingly new without any precedence of the past. The word `New Linguistic World Order’ is no longer just the intangible fascination but an indication of the emerging reality that we are living through a time in which the word ‘linguistic purism’ no longer invokes the sense of self categorization and self identification. The contemporary world of today is linguistically rewarding. This is a time in which the very existence of global, powerful and local needs to be revisited in the context of power shift, demographic shift, social psychological shift and technological shift. Hence, the old linguistic world view has to be challenged in the midst of 21st century. The first years of the 21st century have thus far been marked by the rise global economy, technological revolution and demographic shift, now we are witnessing linguistic shift which is leading towards forming a new linguistic world order. On the other hand, with rising powers of China and India in Asia in tandem the notion of alternative west is set to become a lot more interesting linguistically. It comes at a point when the world is moving towards inclusive globalization due to vanishing power corridor of the west and ascending geopolitical impact of emerging superpower and superpower in waiting. Now it is a reality that the western world no longer continues to rise – in fact, it will have more pressure to act in situation when the alternative west is looking for balanced globalization. It is more than likely that demographically strong languages of alternative west will be in advantageous position. The paper challenges our preconceptions about the nature of sociolinguistic nature of world in the 21st century. It investigates what a linguistic world is likely to be in the future in contrast to what was a linguistic world before 21st century. In particular, the paper tries to answer the following questions: (a) What will be the common linguistic thread across world? (b) How unprecedented transformations can be mapped linguistically? (c) Do we need alternative linguistics to define inclusive globalization as the linguistic reality of the contemporary world has already been reshaped by increasingly integrated world economy, linguistic revolution and alternative west? (d) In which ways these issues can be addressed holistically? (e) Why linguistic world order is changing dramatically? (f) Is it true that the linguistic world around is changing faster than we can even really cope? (g) Is it true that what is coming next is linguistically greater than ever? (h) Do we need to prepare ourselves with new theoretical strategies to address emerging sociolinguistic reality?Keywords: alternative linguistics, new linguistic world order, power shift, demographic shift, social psychological shift, technological shift

Authors: Rohit Kothari, Muneer Mohamed, Vivekanandh K., Sunmeet Sandhu, Preema Sinha, Anuj Bhatnagar
Abstract:
Introduction: Hyper-IgE syndrome is a rare primary immunodeficiency syndrome characterised by triad of severe atopic dermatitis, recurrent pulmonary infections, and recurrent staphylococcal skin infections. The diagnosis requires a high degree of suspicion, typical clinical features, and not mere rise in serum-IgE levels, which may be seen in multiple conditions. Genetic studies are not always possible in a resource poor setting. This study highlights various presentations of Hyper-IgE syndrome in skin of color children. Case-series: Our study had six children of Hyper-IgE syndrome aged twomonths to tenyears. All had onset in first ten months of life except one with a late-onset at two years. All had recurrent eczematoid rash, which responded poorly to conventional treatment, secondary infection, multiple episodes of hospitalisation for pulmonary infection, and raised serum IgE levels. One case had occasional vesicles, bullae, and crusted plaques over both the extremities. Genetic study was possible in only one of them who was found to have pathogenic homozygous deletions of exon-15 to 18 in DOCK8 gene following which he underwent bone marrow transplant (BMT), however, succumbed to lower respiratory tract infection two months after BMT and rest of them received multiple courses of antibiotics, oral/ topical steroids, and cyclosporine intermittently with variable response. Discussion: Our study highlights various characteristics, presentation, and management of this rare syndrome in children. Knowledge of these manifestations in skin of color will facilitate early identification and contribute to optimal care of the patients as representative data on the same is limited in literature.Keywords: absolute eosinophil count, atopic dermatitis, eczematous rash, hyper-immunoglobulin E syndrome, pulmonary infection, serum IgE, skin of color

Authors: Aycan Gurluyer
Abstract:
21st-century theatre has been shaped by lots of world-changing forces devastating human psychology and existence. Accepted as the greatest living English playwright, it is post-war British dramatist Edward Bond who uses a late-21st-century apocalyptic landscape as a weapon to question the human existence in his play 'Have I None?'. In this play, he tries to underline the degenerating and destructive effects of the society and environment on a couple whose lives are changed by an unexpected and annoying stranger. As victim of the society and the cultural corruption, the three vulnerable Bondian characters struggle for their expectations to find a place in this fictional world by sacrificing their own lives. Set in the 2077’s world, the play depicts that rigidly formed rules of the system/authority eliminates the existence of humans. According to Bond, the fascist practices of the governments/systems make people paralyzed in any way, so they choose to deny all realities by becoming biological beings or they gather to commit to suicide as troops. Our main aim is to underscore the questioning of the human existence by drawing the socio-political framework of the era, the capitalist system’s dehumanized individuals and their defence to survive, and what reality is in the 21st century, by focusing on Bond’s hallucinatory and tragic vision of the future in 'Have I None?'.Keywords: Edward Bond, apocalyptic, existence, Have I None?

Authors: Andrzej Kesiak
Abstract:
Contemporary theology is often accused of answering questions that nobody is asking, and of employing hermetic language that has lost its communication capacity. There is also a question that theology is asking itself: how theological discourse can still be influential on other disciplines and, how to overcome the separation of theology and belief. Undoubtedly, in the wider spectrum, the theological discourse has been and will be needed. The difficulty is how to find the right model of it, the model that would help theology to enter in dialogue with culture, art, science, and politics. Presumably, there is no only one such model, theology constantly needs to seek such models, and this is probably a never-ending journey; in other words, theology should adopt a profile of ‘a restless being’ if it wants to remain influential. Music, on the other hand, has always been very close to theology; in fact, a huge part of classical music is either sacred or religious. Many composers sought inspiration in religion, liturgy, religious painting and sacred texts. This paper will argue that despite all that it seems that a proper and factual dialogue is still in a starting phase. Such a thing as a reciprocal relationship between theology and music definitely exists, but it has not yet been theoretically developed enough. Correlation between musical and theological disciplines constitutes a very broad and complex discourse. Therefore this study would rather narrow the subject and put it in a specific context: Theology and Music in the XXI. Century. This paper is a text-based study; therefore it will be based on textual-analysis with elements of the text hermeneutics.Keywords: music, theology, reciprocal relationship between theology and music, XXI Century

Authors: Muhammad Arsalan Mahmoo, Allah Rakha, Muhammad Sohail
Abstract:
The supplementation of wheat flour with high lysine legume flours has positive effects on the nutritional value of bread. In present study, germinated and terminated soya flour blends were prepared and supplemented in bread in variable proportions (10 % and 20 % of each) to check its impact on quality and sensory attributes of bread. The results showed that there was a significant increase in protein, ash and crude fat contents due to increase in the level of germinated and ungerminated soya flour. However, the moisture and crude fiber contents of composite flours containing germinated and ungerminated soya flour decreased with increased level of supplementation. Mean values for physical analysis (loaf volume, specific volume, weight loss and force for texture) were significantly higher in breads prepared with germinated soya bean flour.The scores assigned to sensory parameters of breads like volume, color of crust, symmetry, color of crumb, texture, taste and aroma decreased significantly by increasing the level of germinated and ungerminated soya flour in wheat flour while color of crust and taste slightly improved. The scores given to overall acceptability of bread prepared from composite flour supplemented with 10 % germinated soya flour.Keywords: composite bread, protein energy malnutrition, supplementation, amino acid profile, grain legumes

Authors: Shashank Kumar, Mansi Chandra, Ujjawal Singh, Parth Gupta, Rishi Ram, Arnab Sarkar
Abstract:
Milk is one of the basic and primary sources of food and energy as we start consuming milk from birth. Hence, milk quality and purity and checking the concentration of its constituents become necessary steps. Considering the importance of the purity of milk for human health, the following study has been carried out to simultaneously detect and quantify the different adulterants like urea and starch in milk with the help of a paper-based microfluidic device integrated with a smartphone. The detection of the concentration of urea and starch is based on the principle of colorimetry. In contrast, the fluid flow in the device is based on the capillary action of porous media. The microfluidic channel proposed in the study is equipped with a specialized detection zone, and it employs a colorimetric indicator undergoing a visible color change when the milk gets in touch or reacts with a set of reagents which confirms the presence of different adulterants in the milk. In our proposed work, we have used iodine to detect the percentage of starch in the milk, whereas, in the case of urea, we have used the p-DMAB. A direct correlation has been found between the color change intensity and the concentration of adulterants. A calibration curve was constructed to find color intensity and subsequent starch and urea concentration. The device has low-cost production and easy disposability, which make it highly suitable for widespread adoption, especially in resource-constrained settings. Moreover, a smartphone application has been developed to detect, capture, and analyze the change in color intensity due to the presence of adulterants in the milk. The low-cost nature of the smartphone-integrated paper-based sensor, coupled with its integration with smartphones, makes it an attractive solution for widespread use. They are affordable, simple to use, and do not require specialized training, making them ideal tools for regulatory bodies and concerned consumers.Keywords: paper based microfluidic device, milk adulteration, urea detection, starch detection, smartphone application

Abstract:
The leachate wastewater is high contaminant water; hence it needs to be treated. The objective of this research was to determine the Chemical Oxygen Demand (COD) concentration, Phosphate (PO₄³⁻), Ammonia (NH₃) and color in leachate wastewater in the landfill area. The experiments were carried out in the optimum condition by pH, the Fenton reagent dosage (concentration of dosing Fe²⁺ and H₂O₂). The optimum pH is 3, the optimum [Fe²⁺]/[COD] and [H₂O₂]/[COD₀] = 0.03 and 0.03, respectively. The Biochemical Oxygen Demand (BOD₅)/Chemical Oxygen Demand (COD) ratio can be adjusted to 1 for landfill leachate wastewater (BOD₅/COD = 0.11). From the results, the Fenton process shall be investigated further to achieve the removal of phosphates in addition to COD and color.Keywords: landfill leachate treatment, open dumpsite, Fenton process, wastewater treatment

Authors: Gozde Inal Kiziltepe, Ozgun Uyanik
Abstract:
There is growing evidence that socioeconomic (SES)-related differences in mathematical knowledge primarily start in early childhood period. Preschoolers from low-income families are likely to perform substantially worse in mathematical knowledge than their counterparts from middle and higher income families. The differences are seen on a wide range of recognizing written numerals, counting, adding and subtracting, and comparing numerical magnitudes. Early differences in numerical knowledge have a permanent effect childrens’ mathematical knowledge in other grades. In this respect, analyzing the effect of number board game on the number knowledge of 48-60 month-old children from disadvantaged low-income families constitutes the main objective of the study. Participants were the 71 preschoolers from a childcare center which served low-income urban families. Children were randomly assigned to the number board condition or to the color board condition. The number board condition included 35 children and the color board game condition included 36 children. Both board games were 50 cm long and 30 cm high; had ‘The Great Race’ written across the top; and included 11 horizontally arranged, different colored squares of equal sizes with the leftmost square labeled ‘Start’. The numerical board had the numbers 1–10 in the rightmost 10 squares; the color board had different colors in those squares. A rabbit or a bear token were presented to children for selecting, and on each trial spun a spinner to determine whether the token would move one or two spaces. The number condition spinner had a ‘1’ half and a ‘2’ half; the color condition spinner had colors that matched the colors of the squares on the board. Children met one-on-one with an experimenter for four 15- to 20-min sessions within a 2-week period. In the first and fourth sessions, children were administered identical pretest and posttest measures of numerical knowledge. All children were presented three numerical tasks and one subtest presented in the following order: counting, numerical magnitude comparison, numerical identification and Count Objects – Circle Number Probe subtest of Early Numeracy Assessment. In addition, same numerical tasks and subtest were given as a follow-up test four weeks after the post-test administration. Findings obtained from the study; showed that there was a meaningful difference between scores of children who played a color board game in favor of children who played number board game.Keywords: low income, numerical board game, numerical knowledge, preschool education

Authors: Elmineh Tsegahun Gedif
Abstract:
Zinc oxide nanoparticles (ZnO NPs) have attracted huge attention due to catalytic, optical, photonic, and antibacterial activity. Zinc oxide nanoparticles were successfully synthesized via a fast, non-toxic, cost-effective, and eco-friendly method by biologically reducing Zn(NO3)2.6H2O solution with Neem (Azadirachta indica) leaf extract under optimum conditions (pH = 9). The presence of active flavonoids, phenolic groups, alkaloids, terpenoids, and tannins, which were in the biomass of the Neem leaf extract before and after reduction, was identified using qualitative screening methods (observing the color changes) and FT-IR Spectroscopy. The formation of ZnO NPs was visually indicated by the color changes from colorless to light yellow color. Biosynthesized nanoparticles were also characterized by UV-visible, FT-IR, and XRD spectroscopies. The reduction process was simple and convenient to handle and was monitored by UV-visible spectroscopy that showed surface plasmon resonance (SPR) of the ZnO NPs at 321 nm. This result clearly revealed the formation of ZnO NPs. X-ray diffraction was used to investigate the crystal structure. The average particle size of ZnO powder and around 20 nm using the line width of the plane, and the refraction peak using Scherrer’s equation. The synthesized zinc oxide nanoparticles were evaluated for antimicrobial activities against Gram-positive and Gram-negative bacteria. Zinc nanoparticles exhibited the maximum zone of inhibition against Escherichia coli (15 mm), while the least activity was seen against Staphylococcus aureus.Keywords: antimicrobial activity, azadirachta indica, green synthesis, ZnO NPs

Authors: M. Irannezhad, E. H. N. Gashti, U. Moback, B. Kløve
Abstract:
Climate change because of increases in concentration level of greenhouse gases emissions to the atmosphere will result in mean sea level rise about +1 m by 2100. To prevent coastal floods resulted from the sea level rising, different flood control structures have been built, e.g. the Thames barrier on the Thames River in London (UK), with acceptable protection levels at least so far. Gothenburg located on the southwest coast of Sweden, with the River Göta älv running through it, is one of vulnerable cities to the accelerated rises in mean sea level. Developing a water level model by MATLAB, we evaluated using a sea barrage in the Göta älv River as the flood control structure for protecting the Gothenburg city during this century. Considering three operational scenarios for two barriers in upstream and downstream, the highest sea level was estimated to + 2.95 m above the current mean sea level by 2100. To verify flood protection against such high sea levels, both barriers have to be closed. To prevent high water level in the River Göta älv reservoir, the barriers would be open when the sea level is low. The suggested flood control structures would successfully protect the city from flooding events during this century.Keywords: climate change, flood control structures, gothenburg, sea level rising, water level mode

Authors: Chang-Hsing Lee, Cheng-Chang Lien, Chin-Chuan Han
Abstract:
In this paper, an edge-strength guided multiscale retinex (EGMSR) approach will be proposed for color image contrast enhancement. In EGMSR, the pixel-dependent weight associated with each pixel in the single scale retinex output image is computed according to the edge strength around this pixel in order to prevent from over-enhancing the noises contained in the smooth dark/bright regions. Further, by fusing together the enhanced results of EGMSR and adaptive multiscale retinex (AMSR), we can get a natural fused image having high contrast and proper tonal rendition. Experimental results on several low-contrast images have shown that our proposed approach can produce natural and appealing enhanced images.Keywords: image enhancement, multiscale retinex, image fusion, EGMSR
Procedia PDF Downloads 4572214 Holistic and Naturalistic Traditions of British Hygiene and Medicine, Reflected in E. W. Lane's Hygienic Medicine, 1859
Authors: Min Bae
Abstract:
Hygiene had traditionally meant ways of healthy and right living. However, the nineteenth century was the time when a gradual shift in medical and hygienic paradigms took place from holism to reductionism. Against this medical and social background, E. W. Lane (MD, Edinburgh, 1853) formulated his own medical philosophies in his book Hydropathy: Or Hygienic Medicine (1859). Until the 1880s when he published his last book on the hygienic medicine, he consistently intended to raise the importance of hygienic holism in medicine, while adopting hydropathy as his main therapeutic measure. Lane’s case reflects the mid-nineteenth century trend in which since the 1840s, the rational and holistic facets in medicine had significantly transferred to hydropathy, which was the most naturalistic healing system in the medical market. Hygiene for Lane was no longer the ancient form of ‘six non-naturals’. He emphasised physiology as the rational grounds for his project of the medicalisation of hygiene. His medical philosophy was profoundly naturalistic and holistic against the opposite trend of the contemporary hygiene and medicine. Conflicting aspects may often be best embodied in persons who stood on the boundaries between inside and outside. Lane’s theories on hygienic medicine did not develop into a new medical system which he believed would reconciliate orthodox medicine and hydropathy of his time had also adopted increasingly reductionist approaches since 1860s. Nevertheless, the naturalistic philosophies and approaches in Lane’s hygienic medicine demonstrates a continuous effort for a theoretical reformulation of hydropathy during its stagnant and declining period to constantly fit into the holistic paradigm of medicine and hygiene. Considering the fact that the nature cure concept in hydropathy and its individualistic approach were succeeded by naturopathy at the end of the century, analysis of Lane’s medical thoughts reveals part of a ‘thin red line’ of naturalism in the battleground between reductionism and holism during the nineteenth century in the history of medicine and hygiene.Keywords: E.

Authors: Po-Hao Huang, Pei-Ju Chiang
Abstract:
The structured light 3D scanner is commonly used for measuring the 3D shape of an object. Through projecting designed light patterns on the object, deformed patterns can be obtained and used for the geometric shape reconstruction. At present, Gray code is the most reliable and commonly used light pattern in the structured light 3D scanner. However, the trade-off between scanning efficiency and accuracy is a long-standing and challenging problem. The design of light patterns plays a significant role in the scanning efficiency and accuracy. Thereby, we proposed a novel encoding method integrating color information and Gray-code to improve the scanning efficiency. We will demonstrate that with the proposed method, the scanning time can be reduced to approximate half of the one needed by Gray-code without reduction of precision.Keywords: gray-code, structured light scanner, 3D shape acquisition, 3D reconstruction
Procedia PDF Downloads 4562212 The Planner's Pentangle: A Proposal for a 21st-Century Model of Planning for Sustainable Development
Authors: Sonia Hirt
Abstract:
The Planner's Triangle, an oft-cited model that visually defined planning as the search for sustainability to balance the three basic priorities of equity, economy, and environment, has influenced planning theory and practice for a quarter of a century. In this essay, we argue that the triangle requires updating and expansion. Even if planners keep sustainability as their key core aspiration at the center of their imaginary geometry, the triangle's vertices have to be rethought. Planners should move on to a 21st-century concept. We propose a Planner's Pentangle with five basic priorities as vertices of a new conceptual polygon. These five priorities are Wellbeing, Equity, Economy, Environment, and Esthetics (WE⁴). The WE⁴ concept more accurately and fully represents planning’s history. This is especially true in the United States, where public art and public health played pivotal roles in the establishment of the profession in the late 19th and early 20th centuries. It also more accurately represents planning’s future. Both health/wellness and aesthetic concerns are becoming increasingly important in the 21st century. The pentangle can become an effective tool for understanding and visualizing planning's history and present. Planning has a long history of representing urban presents and future as conceptual models in visual form. Such models can play an important role in understanding and shaping practice. For over two decades, one such model, the Planner's Triangle, stood apart as the expression of planning's pursuit for sustainability. But if the model is outdated and insufficiently robust, it can diminish our understanding of planning practice, as well as the appreciation of the profession among non-planners. Thus, we argue for a new conceptual model of what planners do.Keywords: sustainable development, planning for sustainable development, planner's triangle, planner's pentangle, planning and health, planning and art, planning history

Authors: Dalrún Kaldakvísl Eygerðardóttir
Abstract:
Shark fishing has been practiced for centuries in Iceland. The broad objective of this ongoing research is to study the history of shark fishing in Iceland from the high days of Icelandic shark fishing in the latter half of the 19th century to recent days. The main focus is on shark fishing in the 20th and 21st century. The research sheds light on how sharks have shaped the Icelandic society and how Icelandic society has shaped the lives of sharks, by providing historical context to the relationship between Icelanders and one of the top predators in the North Atlantic Ocean, the Greenland shark. It is important to explore this aspect of Icelandic history further, to enhance people´s understanding of the marine ecosystem from the context of the past and the current increasing concerns about the status of sharks worldwide. Next to nothing has been written about shark fishing in the 20th and 21st Iceland, which shows the importance of interviewing shark fishermen – most of whom are at an old age today. The main methodology used in the research is oral history. Oral history is a large and growing field of research within history, which is based on obtaining oral sources through interviews, analyzing them, and presenting them. The video-poster sheds light on how oral history provides useful historical information on shark fishing and shark conservation in Iceland.Keywords: oral history, shark fishing in Iceland, 19. and 21. century, shark conservation, marine environmental history

Authors: Xuanyu Bai
Abstract:
“The Communist Manifesto”, written by Karl Marx and Friedrich Engels, is one of the most significant documents throughout the whole history which covers across different fields including Economic, Politic, Sociology and Philosophy. Instead of discussing the Communist ideas presented in the Communist Manifesto, the essay focuses on exploring the reasons that contributed to the popularization of the document and its influence on political revolutions in 19th century Europe by concentrating on the document itself along with other primary and secondary sources and temporal artwork. Combining the details from the Communist Manifesto and other documents, Marx’s writing style and word choice, his convincible notions about a new society dominated by proletariats, and the revolutionary idea of class destruction has led to the popularization of the Communist Manifesto and influenced the latter political revolutions.Keywords: communist manifesto, Marx, Engels, capitalism

Authors: Yavuz Arat, Ugur Tuztasi, Mehmet Uysal
Abstract:
Anatolia has been the host of many civilizations and a site where architectural structures of many cultural layers were interpreted. Most significantly the Turks who settled in Central Asia brought their architectural dynamics and cultural accumulation to Anatolia after the 12th century. The tomb structures first observed in Central Asia under the influence of Islamic faith and Turkish cultural heritage has blossomed under Great Seljuk Empire and with the Anatolian Seljuk Empire these tombs changed both in size and form with rich and beautiful samples from Ahlat to Sivas to Kayseri and Konya. This tomb tradition which started during 13th century has continued during the Ottoman Empire period with some alterations of form and evolved into the rarely observed mausoleum type tombs. The Ottoman tradition of building tombs inside mosque gardens and their forms present the clues of an important burial tradition. However this understanding was abandoned in 20th century Turkey. This tradition was abandoned with regard to legal regulations and health conditions. This study investigates the vestiges of this tradition and its spatial reflections over a sample. The present sample is representative of a tradition that started in 1970s and the case of building tombs inside mosque gardens will be illustrated over the tomb of Hacı Kemal Onsun and his wife which is located in Konya, the capital of the Anatolian Seljuks. The building process of this tomb will be evaluated with regard to burial traditions and architectural stylization.Keywords: tomb, language of architectural form, Anatolian Seljuk tombs, Ottoman tombs

Authors: R. Manjula, Kaustav Bagchi, Sushant Ramesh, Anush Baskaran
Abstract:
In the past century, the emergence of information technology has had a significant positive impact on human life. While companies tend to be more involved in the completion of projects, the turn of the century has seen importance being given to investment in information security policies. These policies are essential to protect important data from adversaries, and thus following these policies has become one of the most important attributes revolving around information security models. In this research, we have focussed on the factors affecting information security policy compliance in two models : The theory of planned behaviour and the integration of the social bond theory and the involvement theory into a single model. Finally, we have given a proposal of where these theories would be successful.Keywords: information technology, information security, involvement theory, policies, social bond theory

Authors: Hassan Masoumi, Ahad Salimi, Nazanin Barhemmat, Babak Gholami
Abstract:
Artificial neural networks have gained a lot of interest as empirical models for their powerful representational capacity, multi input and output mapping characteristics. In fact, most feed-forward networks with nonlinear nodal functions have been proved to be universal approximates. In this paper, we propose a new supervised method for color image classification based on self organizing feature maps (SOFM). This algorithm is based on competitive learning. The method partitions the input space using self-organizing feature maps to introduce the concept of local neighborhoods. Our image classification system entered into RGB image. Experiments with simulated data showed that separability of classes increased when increasing training time. In additional, the result shows proposed algorithms are effective for color image classification.Keywords: classification, SOFM algorithm, neural network, neighborhood, RGB image

Authors: Ly Quyet Tien
Abstract:
The object of this paper is to study Vietnamese Les Rap as art to promote rights and gender in the twenty-first century. The author analyzed Vietnamese Les Rap from the point of view of a contemporary person who has witnessed the tumultuous destiny of the most suffering minority group in Vietnam’s LGBT community. He reviewed scholarly studies, and reputable newspapers on the topic and conducted face to face interviews for qualitative data. The study found that Vietnamese lesbians have composed and used rap as an effective tool to express their fight for visibility, identity, and sensibility. Research reveals that these songs did not only touch the heart of the LGBT community but also the larger public, marking the rising queer voice, contributing to a flourishing of LGBT culture, and revolutionizing the colors of Vietnamese hip hop music in the twenty-first century.Keywords: culture, lesbian, rap, Vietnam

Authors: Zimasa Siyasanga Gysman
Abstract:
This paper assesses the history of electronic music and its performance to illustrate that machines and technology have largely influenced how humans perform electronic music. The history of electronic music mainly focuses on the composition and production of electronic music with little to no attention paid to its performance by the majority of scholars in this field. Therefore, establishing a history of performance involves investigating what compositions of electronic music called for in the production of electronic music performance. This investigation into seminal works in the history of electronic music, therefore, illustrates the aesthetics of electronic music performance and the aesthetics established in the very beginnings of electronic music performance demonstrate the aesthetics of electronic music which are still prevalent today. The key aesthetics are the repurposing of technology and the hybridisation of technology. Performers take familiar technology (technology that society has become accustomed to using in daily life), not necessarily related to music or performance and use it as an instrument in their performances, such as a rotary dial telephone. Likewise, since the beginnings of electronic music, producers have always experimented with the latest technologies available to them in their compositions and performances. The spirit of performers of electronic music, therefore, revolves around repurposing familiar technologies and using them in new ways, whilst similarly experimenting with new technologies in their performances. This process of hybridisation plays a key role in the production and performance of electronic music in the twentieth century. Through various interviews with performers of electronic music, it is shown that these aesthetics are driving performance practices in the twenty-first century.Keywords: body, hybridisation, performance, sound

Authors: Nikolaos Mavropoulos
Abstract:
Imperialism and colonialism had and still have a predominantly negative nuisance. In many ways the two terms are synonyms of racist behavior, exploitation, and oppression, imposed by the supposedly civilized West at Africa’s and Asia’s expense. Paradoxically enough, imperialism was not thoroughly negative for some Marxist scholars. For them, in reality, it served a historical necessity as the only mean to liberate the backward societies from their millennial stagnation and to introduce them to industrialization and progress. To Marx as immoral and cruel the imposition of imperial rule and the eradication of traditional structures may have been, the process is still a progressive step towards the formation of class consciousness, global revolution and socialism in a world scale. Overlooking the fact that imperialism could actually delay and put an end to capitalist development, some Marxists proponents considered it as a positive development for the colonized peoples.Keywords: Colonialism, , Marxist theory, Modern history, , 19th century Imperialism,
