Textiles in Bali have traditionally played a vital role in the social economic and religious life of the people. Textiles defined the status of the individual in term of both costume and wealth. Use of the various textiles is in Balinese tradition dictated primarily by rules of the Hindu-Balinese faith. Cloths and clothing are employed in worship of God and the ancestors. Gold songket patterned textiles are perceived as symbol of wealth and prestige and provide a fitting display of affluence at important cerenlonial events. The specialized pieces of clothing, temple banners and hangings are unique to each tribal group ranging from weft -patterned textiles in Bali. The impact of Indian ideas and techniques was important in the field of textiles, and many of the characteristics in Bali's fabric design derived from Hindu-Buddhist mythology that has furnished subject-matter for songket textile art. The purpose of this study is to examine the background of Balinese culture and to define the characteristics of Hindu-Balinese textiles. The songket textile design also analyzes by examing the techniques of songket weaving and the meaning of design, pattern, and motif. Many design and motifs convey important messages significant only to those familiar with the particular social religious principle of people who have produced them. It is only by seeing cloths in their cultural context that we can begin to understand their true value and meaning.

As RFID/USN technology is used in the latest industry trend, the information analysis paradigm shifts to intelligence service environment. The intelligent service includes autonomic operation, which select activity by defining itself to the status of industry facilities. Furthermore, information analysis based on IT used to frequently data mining for detecting the meaning information and deriving new pattern. This paper suggest self-classifying of context-aware by applying data mining in gas facilities for serving the intelligent gas safety management. We modify data algorithm for fitting the domain of gas safety, construct context-aware model by using the proposed algorithm, and demonstrate our method. As the accuracy of our model is improved over 90%, the our approach can apply to intelligent gas safety management based on RFID/USN environments.

Purpose: To investigate the status of foot, preventive foot care and appropriateness of shoe size in patients with diabetes. Materials and Methods: One hundred and sixty-five patients who visited endocrinology clinic due to clinically proven diabetes mellitus were studied. Average age was 59.3 years (range, 36-90 years) and average duration of diabetes was $9.6{\pm}8.2$ years. Patients were questioned about their basic educational level and their foot and ankle problems. Physical examination of the foot was done including sensation testing of four areas of plantar surface with the 5.07 monofilament. Both feet and shoes were measured for width, length and the height of toes and toebox. Shoes were defined as properly fitting the foot if it is 5mm wider than the foot, and $20{\pm}30\;mm$ longer than the foot, and the height of toebox is more than 5mm higher than the height of the toes. Results: 48.5 percent of the patients were educated about how to select an appropriate shoewear. 47.3 percent of the patients had symptoms of neuropathy and 42.4 percent of patients were unable to feel the monofilament in at least one area. 25.5 percent of the patients had appropriate shoes in length, 63.6 percent of the patients in width, and 72.7 percent of the patients in the height of toebox. Conclusion: This study suggets that more patients needs to be educated about foot care and appropriate shoes which have adequate height of toebox as well as the length and width.

A carbonaceous sorbent was prepared from rice husk via sulphuric acid treatment. After preparation and washing, the wet carbon with moisture content 85% was used in its wet status in this study due to its higher reactivity towards Cr(VI) than the dry carbon. The interaction of Cr(VI) and the carbon was studied and two processes were investigated in terms of kinetics and equilibrium namely Cr(VI) removal and chromium sorption. Cr(VI) removal and chromium sorption were studied at various initial pH (1.6-7), for initial Cr(VI) concentration (100 mg/l). At equilibrium, maximum Cr(VI) removal occurred at low initial pH (1.6-2) where, Cr(III) was the only available chromium species in solution. Cr(VI) removal, at such low pH, was related to the reduction to Cr(III). Maximum chromium sorption (60.5 mg/g) occurred at initial pH 2.8 and a rise in the final pH was recorded for all initial pH studied. For the kinetic experiments, approximate equilibrium was reached in 60-100 hr. Cr(VI) removal data, at initial pH 1.6-2.4, fit well pseudo first order model but did not fit pseudo second order model. At initial pH 2.6-7, Cr(VI) removal data did not fit, anymore, pseudo first order model, but fit well pseudo second order model instead. The change in the order of Cr(VI) removal process takes place in the pH range 2.4-2.6 under the experimental conditions. Other two models were tested for the kinetics of chromium sorption with the data fitting well pseudo second order model in the whole range of pH. An increase in cation exchange capacity, sorbent acidity and base neutralization capacity was recorded for the carbon sorbent after the interaction with acidified Cr(VI) indicating the oxidation processes on the carbon surface accompanying Cr(VI) reduction.

건강 관련 삶의 질 자료는 정규분포를 따르지 않고 치우친 분포를 보이며, 등분산 가정을 만족하지 않는 경우가 대부분이다. 또한 건강 관련 삶의 질 자료는 범위가 정해져 있는 자료이며, 건강한 상태를 나타내는 경우 최대값을 가지는 천장효과가 있는 자료이다. 본 연구에서는 건강 관련 삶의 질 자료인 EQ-5D에 대해 선형회귀모형과 베타회귀모형, 그리고 평균과 정밀도에 대한 하위모형을 가지고 있는 확장된 베타회귀모형을 이용하여 예측모형을 개발하고 모형의 예측 정확도를 비교하였다. 선형회귀모형에 비해 확장된 베타회귀모형의 예측 정확도가 높기는 하지만 신뢰구간이 겹치고 있기 때문에 확장된 베타회귀모형의 정확도가 더 높다고 할 수는 없다. 하지만 확장된 베타회귀모형은 공변량에 따라 분산이 달라지는 부분을 설명할 수 있으며 선형회귀모형이 제한된 범위를 벗어난 값을 예측하는 부분을 개선할 수 있다. 따라서 범위가 제한되고 이분산이 있는 치우친 자료에 대해 공변량들이 평균 및 정밀도에 영향을 주는 정도를 동시에 고려하는 확장된 베타회귀모형은 건강 관련 삶의 질 자료인 EQ-5D를 분석하는 방법으로 적절하다고 할 수 있다.

The purpose of this study is firstly to survey the social and cultural background of 20th century and women´s status, and to identify what the ideal body is like and what the elements of outer garment and underwear are and the techniques to incarnate the ideal beauty. Various papers are referenced for theoretical study and the elements and techniques of underwear are analyzed based on photographical materials. This paper concludes as follows. In 1960´s, ideal beauty was small bust, long legs, which showed extremely slim Mini-skirt look. Thinly or no padded brassiere were worn for small bust, and pants-style short panty girdles were popular as they used to wear pants frequently. Lycra replaced all the closures, bones, seams and gave freedom with light weight. In 1970´s, a natural human body without sex specific was in vogue. Therefore, the non-structural knits without a pad or lining or the shirts dress were widespread for a Natural look and the naturally molded brassiere or girdles were worn as the underwears. In 1980´s, the women with powerful muscle appear which emphasized liveliness and healthfulness. The body conscious represented by wide shoulder, plump breast, accented waist, small hips, and long legs has been embodied. Outer garments emphasized women power and healthy beauty with Power suit and Form-fitting style, and underwears made the breast plump with padded brassiere and emphasized waist and hips with waspie. In 1990´s, ideal beauty was slim body with big bust and the outer garments emphasized body line of women with Hourglass silhouette. Push-up bra which emphasizes the valley of breast and supports the breast upward and the control tights for slim waist, flat abdomen, small hips, and long and slim legs have been useful as underwears. Multi-functional micro-fiber has been ideal for sculpting women body.

Background: The Cox PH model is one of the most significant statistical models in studying survival of patients. But, in the case of patients with long-term survival, it may not be the most appropriate. In such cases, a cure rate model seems more suitable. The purpose of this study was to determine clinical factors associated with cure rate of patients with breast cancer. Materials and Methods: In order to find factors affecting cure rate (response), a non-mixed cure rate model with negative binomial distribution for latent variable was used. Variables selected were recurrence cancer, status for HER2, estrogen receptor (ER) and progesterone receptor (PR), size of tumor, grade of cancer, stage of cancer, type of surgery, age at the diagnosis time and number of removed positive lymph nodes. All analyses were performed using PROC MCMC processes in the SAS 9.2 program. Results: The mean (SD) age of patients was equal to 48.9 (11.1) months. For these patients, 1, 5 and 10-year survival rates were 95, 79 and 50 percent respectively. All of the mentioned variables were effective in cure fraction. Kaplan-Meier curve showed cure model's use competence. Conclusions: Unlike other variables, existence of ER and PR positivity will increase probability of cure in patients. In the present study, Weibull distribution was used for the purpose of analysing survival times. Model fitness with other distributions such as log-N and log-logistic and other distributions for latent variable is recommended.
