In the cultural realm of Hinduism centering around India, traditional costumes such as Sari, and Dhoti are worn up to date under the influence of religious faith, tradition, and fundamentalism. The purpose of this study is to clarify the religious meaning of unstitched traditional Indian costume and inquire into the figurative beauty of it. This study revolved around India, and the aesthetic feature affected by hinduism was examined based on the literature references and the figurative feature and aesthetic value of unstitched costume were analyzed. The most important feature of Indian costume is the unstitched costume without joining pieces of cloth by using a needle and thread, symbolizing the purity based on the cosmology of Hindu. In the unstitched costume of India, natural drapery that is the large cloth, slipped or tied on body, wrapping it affluently, is emphasized. Unstitched costume of India, based on cosmology of Hindu and the concept of purity, is still broadly worn by people under the influence of fundamentalism and conservative atmosphere. Religious idea is expressed and a beauty of concealment, emphasizing the chastity, is shown in the unstitched costume of India, while a beauty of nature is distinctively revealed in the non-structural and asymmetric drapery costume due to the unique wearing style. In addition, 'A beauty of symbolism' appears in the wearing method, color, the part of wearing, and ornament. Religion has affected overall culture that is inclusive art, aesthetics, and social structure and has contributed to the formulation of costume style. Unstitched costume of India is the unique tradition of India and identity, based on the religious idea.

Background: The purpose of this study is to examine the characteristics of and factors associated with long-term care (LTC) utilization under public long-term care insurance (LTCI) among end-of-life older adults in Korea. Methods: Using a 5% sample of older people aged 65 or older and their health and LTC insurance data, two-part model analyses were conducted. We compared LTC uses and their determinants during the last year of life among decedents in the year 2010 with those of survivors. We also compared the medical uses of the same sample with their LTC uses. Results: The end-of-life elderly were more likely to use LTC, and their expenditure on LTC was higher than their counterparts. Whether or not older people used LTC during their last year of life was significantly affected by age, sex, health insurance, household income, and living alone; however, LTC costs of the decedents were only affected by functional status, which may have been due to the reimbursement scheme of the current LTCI, which is mainly based on functional dependency level. For the survivors, having chronic diseases significantly increased the likelihood of LTC use, which was not the case for the decedents. End-of-life elderly with relatively low social economic status were more likely to use the LTC other than medical services, while the health conditions affected their medical uses most significantly. Conclusion: The study findings provide key information for predicting demand related to the increasing LTC needs of Korean older people at the end of life.

Recently, in order to enhance the function and usefulness of products, cladding of dissimilar materials that maximizes the performance of the material is being widely used in all areas of industry as an important process. Clad steel plate, produced by cladding stainless steel plate, an anticorrosive material, on carbon steel plate, is being used to produce pressure vessels. Stainless steel plate has good corrosion resistance, and carbon steel plate has good rigidity and strength; clad steel can satisfy all of these qualities at once. This study aims to find the ${\delta}$-ferrite behavior, mechanical properties, structure change, integrity and reliability of clad steel weld on hot rolled steel plates. For this purpose, multi-layer welding, repair welding and post weld heat treatment were implemented according to welding procedure specifications (WPS). In order to observe the mechanical properties and toughness of clad steel weld zone, post weld heat treatment was carried out according to ASME Sec. VIII Div.1 UW-40 procedure for post weld heat treatment. With heat treatment at $625^{\circ}C$, the hold time was used as the process variable, increased by intervals that were doubled each time, from 80 to 1,280 min. The structure of weld part was typical cast structure; localized primary austenite areas appeared near central vermicular ferrite and fusion line. The heat affected zone showed rough austenite structure created by the weld heat input. Due to annealing effects of heat treatment, the mechanical properties (tensile strength, hardness, impact value) of the heat affected area tended to decrease. From the results of this study, it is possible to conclude the integrity of clad steel welds is not affected much in field welding, repair welding, multi-layer welding, post weld heat treatment, etc.

The purpose of the present study was to assess food hygiene and safety knowledge, attitudes, and practices of food-service personnel in school food-service programs and to find factors affecting their knowledge, attitudes, and practices. A self-administered questionnaire was offered to a random sample of 40 kitchen employees in elementary schools in one region of Korea, with 37 completing the survey, a response rate of 92.5%. The survey was carried out over a two-month period (April-May, 2001). Knowledge score of the employees was high with a mean/standard deviation of 4.75/0.32 on a 5.0-point scale. They had significantly lower attitude score (4.55$\pm$0.33) and practice score (4.55$\pm$0.45) compared to the score of knowledge (p＜0.05). Logistic regression analysis showed that (1) the employees＇ education level and work experience in school food-service programs affected their knowledge, (2) age, level of living, monthly income, and housing type affected their attitudes, and (3) monthly income, level of living, housing type, and work experience in school food-service programs affected their practices. Pearson＇s correlation analysis confirmed that the knowledge and attitude scores were significantly correlated (r=0.598, p＜0.001). The results indicate that the knowledge, attitude, and practice levels of the employees regarding the food hygiene and safety were better than expected, however, the results suggest a need for the adoption of approaches which take account of socio-economic and environmental influences on behavior to improve and maintain their practice level. The food-handling practices of school food-service employees need to be monitored routinely in order to ensure that safe food is served to our school children.

The development of sustainable smut management techniques requires an understanding of the impacts of smut on sugarcane growth and the relationships between smut intensity and meteorological variables, varieties, and crop types. Thus, assessments were made with the objectives to 1) determine the effect of smut on the above-ground growth of sugarcane, and 2) quantify the association of smut with weather variables, varieties and crop types. The effect of smut on above-ground growth was assessed in six fields planted with NCo 334 (wider coverage) having 6 months of age in Fincha and Metehara fields in 2021. Data on above-ground growth were taken from 20 randomly selected smut-affected and healthy stools from each field. Besides, 6 years' data (2015 to 2021) on the numbers of smut-affected stools and smut whips of 79 fields were collected. Furthermore, 10 years' (2011 to 2021) weather data were acquired from the sugar plantations. The results demonstrated reduction in the above-ground growth of sugarcane in the range of 18.39% and 73.42% due to smut. In addition, weather variables explained about 68.48% and 66.58% of the variability in the number of smut-affected stools and whips respectively. Smut intensity increased with crop types for susceptible varieties. The tight association between the smut epidemic and crop types, varieties, and weather, implied that these parameters must be carefully considered in management decisions. Continuous monitoring of smut disease, meteorological variables, varieties, and crop types in all the sugarcane plantations could be done as a part of integrated smut management in the future.

As part of further study on Gwangseungri coastal deposits which occurred at 10 ~ 15m above sea level and was analyzed as palaeo-coastal flood-type sediments, six burial ages of six additional samples from the two cross sections (KST1 and, KST2) near to the points of the past study were estimated and the geochemical analysis was performed. Further investigation on the cross section KST1 revealed a reversal of the burial age at the bottom of the section which was identified as palaeo-flooding sediments and supposed to have been buried about 350 years ago. At the lower part of the KST1, the burial age of the sediment layer was estimated to be 3,800 years. The lower part of KST2 sediments was identified as sediments that was formed about 6,600 years ago and about 20,000 years ago. Considering the inclination of the sediment layers, the coastal flooding sedimentsreported to have formed 700 years ago in the previousstudy are located at the top and the KST1 section analyzed in thisstudy seemed to be connected to the lower part. The chemical analysis showed that the relationship between these layers was not continuous but had a discontinuous characteristic influenced by a specific event, and the chemical composition also showed a rapid change. If we judge these together, the lowest part of Gwangseungrisediment layerseemed to have formed during the last glacial period but it was hard to find its origins clearly. On top of this layer, a fine sediment layer containing gravels was also formed.Itseemed thatsedimentation did not occur continuously, but was affected by temporary events in such a way that after a sediment layer was formed, it stopped. Since then, a coastal flooding event occurred about 700 years ago, and part of flooded sediments accumulated in the rear slope. After that, when a flood layer including additional granular materials about 350 years ago was formed, sedimentation along the slope seemed to have occurred.

The purpose of this study was to determine the optimal distances between pipes to minimize the pressure loss and turbulent intensity. This was accomplished by investigating the distances between sleeve-jointed pipes and the flow changes in pipes based on variations in the Reynolds (Re) number when installing adjusting pieces for the pipes. When the thickness tp of the sleeve-jointed piping was fixed at 5 mm and the pipe lengths Lp were 10, 50, 100, and 200 mm, the correlations with the velocity of the sleeve-jointed part, pressure distribution, length of the reattachment point in the recirculation area, and Re number were analyzed. The flow characteristic of the sleeve-jointed part from a laminar to a turbulent flow region was determined by setting the Re range to 200 ≤ Re ≤ 5,000. This was done by utilizing Ansys Fluent 18.1, which is a commercial program. The enlargement and contraction ratios of the sleeve-jointed part were 1.2 and 0.83, respectively, and the turbulent intensity of the sleeve downstream edge and pressure change both increased as the Re number increased while Lp remained constant. The fact that the flow on the sleeve wall surface was disturbed by tp resulted in losses in velocity energy. Therefore, the edge of the sleeve-jointed part was also effected. When Lp was 10 mm or less, the turbulent intensity of the edge part did not change significantly as the Re number increased. The reattachment point in the recirculation area did not appear at Lp of 10 mm or less and was not affected by the vortex. In the case of 3,000 ≤ Re, the reattachment length of the wall surface of the sleeve-jointed part was nearly constant as Lp increased.

The purpose of the study was to identify the degree of social support and burden in mothers of children with cancer, and to determine a strategy of an effective social support utility for burden relief in these mothers. The subjects of this study were consisted of mothers of cancer children, registered at a'C'University affiliated hospital in Taejon. The data was collected from July 1 to August 31, 1994. Three instruments were used to collect the data : a semi-structured interview questionnaire which was developed by the researcher was used to identify the content of the mother's burden, a Visual Analogue Scale(VAS) that had a 10cm horizontal line was used to measure the degree of mother's burden and the PRQ part I & part Ⅱ were used to measure the degree of mother's social support. The content of mother's burden collected through in depth interviews was analyzed using content analysis. Also burden and social support data were analyzed by SAS program. The result of this study were summarized as follows : 1. The data on burden content from the interview were categorized as psychological, physiological, family interaction with maternal role, financial burden and personal interaction with social relational burden. 2. The degree of burden measured by VAS had a mean of 8.04(range from 0.5 to 10). 3. The score for social support measured by PRQ part Ⅱ had a mean of 88.9(range from 71 to 113). The highest scores was for reassurance of worth. The lowest score was for opportunity for nuturance. Most of the 15 mothers received the greatest amount of support from their sisters, spouse, friends, neighbors, relations, priest were perceived as eaningful resource person. 4. The correlation coefficient of burden and social support was somewhat negative correlation but no statistical significance(r=-.072). Therefore, a further study is necessary to repeat the qualitative research for exploring factor to be affected family caregiver's burden according to disease proceeding stage. On the basis of the results from this study, future research will be promoted valid and reliable tool development. Through this study, nurses understand and assess the individual psychologic burden and further it would be recommendated to produce professional education program for pediatric oncologic specialist nurse.
