Abstract:

Background: Palliative care is caring holistically for patients and families to improve their quality of life. The approach by a multidisciplinary team requires integrated collaboration based on sufficient knowledge of the principles of palliative care as a whole, especially for nurses. Therefore, this study wants to find out the level of knowledge about palliative care of the nurses along the relationship with attitude and performance. Method: This study applies cross-sectional survey design and allows the respondents to fill two questionnaires to determine the level of knowledge and attitude toward palliative care, while one questionnaire is filled by the head nurse to evaluate nurses’ performance. The relationship was analyzed by Spearman rho’s correlation in alpha < 0.05 by SPSS. Results: The majority of respondents were females, age above 25 years old, and married. Most of the nurses are staff nurses and the ratio of education level is not significantly different. The knowledge level is poor, while the attitude and performance are in adequate level. Knowledge may affect attitude, but it does not happen toward performance. Conclusion: There is a need for increased knowledge about palliative care to improve attitude and work performance. Future researchers might use this finding as reference to conduct further study in improving knowledge of palliative care.

Keywords: Knowledge, attitude, work performance, palliative care.

Abstract:

Maintenance is one of the most important activities in the shipyard industry. However, sometimes it is not supported by adequate services from the shipyard, where inaccuracy in estimating the duration of the ship maintenance is still common. This makes estimation of ship maintenance duration is crucial. This study uses Data Mining approach, i.e., CART (Classification and Regression Tree) to estimate the duration of ship maintenance that is limited to dock works or which is known as dry docking. By using the volume of dock works as an input to estimate the maintenance duration, 4 classes of dry docking duration were obtained with different linear model and job criteria for each class. These linear models can then be used to estimate the duration of dry docking based on job criteria.

Keywords: Classification and regression tree (CART), data mining, dry docking, maintenance duration.

Abstract:

There is long history of konjac tubers being used as a cure for certain diseases in China and Japan. Konjac flour is prepared from konjac tubers and it contains high concentration of glucomannan. Konjac Glucomannan (KGM) is dietary fiber and the role of which has been demonstrated in weight reduction, lowering blood cholesterol and sugar level, promoting intestinal activity etc. Konjac glucomanan has a property of swelling by absorbing water, more than a hundred times its own weight. Therefore it helps increasing weight of feces, water content of feces, and promotes satiety feeling. Mode of actions of dietary fibre as laxatives agents includes holding water inside the bowel lumen, inhibition of water absorption in the colon and stimulating colonic motility. Number of fecal pellets did not effected in rats were fed on 300 and 600 mg/kg of konjac flour, as well as constipated control and Dulcolax treatment. Water content, weight of fecal pellets and gastrointestinal transit ratio were higher in rats treated with 600 mg/kg than 300 mg/kg of konjac flour. Rats were administered with Dulcolax showed the highest gastrointestinal transit ratio, followed by 600 mg/kg konjac flour. The lowest feed consumption was noted in 600 mg/kg konjac flour diet group.

Keywords: Laxative, konjac flour, Amorphophallus muelleri Blume, glucomannan, constipation.

Abstract:

Contamination of aromatic compounds in water can cause severe long-lasting effects not only for biotic organism but also on human health. Several alternative technologies for remediation of polluted water have been attempted. One of these is adsorption process of aromatic compounds by using organic modified clay mineral. Porous structure of clay is potential properties for molecular adsorptivity and it can be increased by immobilizing hydrophobic structure to attract organic compounds. In this work natural montmorillonite were modified with cetyltrimethylammonium (CTMA+) and was evaluated for use as adsorbents of aromatic compounds: benzene, toluene, and 2-chloro phenol in its single and multicomponent solution by ethanol:water solvent. Preparation of CTMA-montmorillonite was conducted by simple ion exchange procedure and characterization was conducted by using x-day diffraction (XRD), Fourier-transform infra red (FTIR) and gas sorption analysis. The influence of structural modification of montmorillonite on its adsorption capacity and adsorption affinity of organic compound were studied. It was shown that adsorptivity of montmorillonite was increased by modification associated with arrangements of CTMA+ in the structure even the specific surface area of modified montmorillonite was lower than raw montmorillonite. Adsorption rate indicated that material has affinity to adsorb compound by following order: benzene> toluene > 2-chloro phenol. The adsorption isotherms of benzene and toluene showed 1st order adsorption kinetic indicating a partition phenomenon of compounds between the aqueous and organophilic CTMAmontmorillonite.

Keywords: Adsorption, Desorption, Montmorillonite, Organoclay, Surfactant.
