서울시 25개 자치구가 운영하는 생활폐기물 적환시설을 대상으로 시설의 기능, 지역 친화성, 규범 순응성 등의 3개 영역에 대해 현황을 분석하고 개선방안을 모색하였다. 65개 적환장 중 46개소는 매일 반출이 필요한 대량폐기물을, 19개소는 3~30일 범위에서 체류 후 반출되는 소량폐기물을 다루었다. 57%의 시설이 주거지역과 상업지역에 설치되어 있었다. 또한 57%의 적환장은 나대지 위에 장비만 두고서 적환작업을 하였다. 79%의 적환장은 재활용선별장 같은 시설과 근접하지 않고 독립적으로 존재했다. 도시계획법의 의한 환경기초시설로 지정된 경우는 17%에 불과했고, 폐기물관리법의 규정대로 허가받은 수집 운반업자가 운영하는 적환장은 31% 수준이었다. 적환장은 그 역할에서 시설 최적화, 자원화 확대 같은 정부의 폐기물관리 정책과 부합하였으나 주거지역이나 상업지역 같은 도심에 입지하기에는 환경대책이 미흡하고 규범과 불일치하는 면이 있었다. 앞으로 적환장이 도심의 환경기초시설로 자리매김하려면 건물 밀폐화, 기능의 종합화 등의 과제를 풀어야 한다.

It is experienced fact that unreasonable design criterion and unsitable operation management for the agricultural structures including reservoirs based on short terms data of monthly flows have been brought about not only loss of lives, but also enormous property damage. For the solution of this point at issue, this study was conducted to simulate long series of synthetic monthly flows by multi-season first order Markov model with selection of best fitting frequency distribution and to make a comparison of statistical parameters between observed and synthetic flows of six watersheds in Yeong San and Seom Jin river systems. The results obtained through this study can be summarized as follows. 1.Both Gamma and two parameter lognormal distribution were found to be suitable ones for monthly flows in all watersheds by Kolmogorov-Smirnov test while those distributions were judged to be unfitness in Nam Pyeong of Yeong San and Song Jeong and Ab Rog watersheds of Seom Jin river systems in the $\chi$$^2$ goodness of fit test. 2.Most of the arithmetic mean values for synthetic monthly flows simulated by Gamma distribution are much closer to the results of the observed data than those of two parameter lognomal distribution in the applied watersheds. 3.Fluctuation for the coefficient of variation derived by Gamma distribution was shown in general as better agreement with the results of the observed data than that of two parameter lognormal distribution in the applied watersheds both in Yeong San and Seom Jin river systems. Especially, coefficients of variation calculated by Gamma distribution are seemed to be much closer to those of the observed data during July and August. 4.It can be concluded that synthetic monthly flows simulated by Gamma distribution are seemed to be much closer to the observed data than those by two parameter lognormal distribution in the applied watersheds. 5.It is to be desired that multi-season first order Markov model based on Gamma distribution which is confirmed as a good fitting one in this study would be compared with Harmonic synthetic model as a continuation follows.

An original sensor system based on Fiber Bragg Gratings (FBG) for the strain monitoring of an adaptive wing element is presented in this paper. One of the main aims of the SARISTU project is in fact to measure the shape of a deformable wing for performance optimization. In detail, an Adaptive Trailing Edge (ATE) is monitored chord- and span-wise in order to estimate the deviation between the actual and the desired shape and, then, to allow attaining a prediction of the real aerodynamic behavior with respect to the expected one. The integration of a sensor system is not trivial: it has to fit inside the available room and to comply with the primary issue of the FBG protection. Moreover, dealing with morphing structures, large deformations are expected and a certain modulation is necessary to keep the measured strain inside the permissible measure range. In what follows, the mathematical model of an original FBG-based structural sensor system is presented, designed to evaluate the chord-wise strain of an Adaptive Trailing Edge device. Numerical and experimental results are compared, using a proof-of-concept setup. Further investigations aimed at improving the sensor capabilities, were finally addressed. The elasticity of the sensor structure was exploited to enlarge both the measurement and the linearity range. An optimisation process was then implemented to find out an optimal thickness distribution of the sensor system in order to alleviate the strain level within the referred component.

The purpose of this study is to develop comfortable patient gown for spinal surgery patients. The results of the survey confirmed inconveniences and problems with the current gown, and a new gown style was recommended. The recommended changes addressed design, pattern, and materials. The final experimental design for the top of the new patient gown is a wrap style that moves the center opening of the gown to the side and enables patients to control the length of the sleeves by attaching two snaps. The cutting line is aligned with the back brace location, and the issue of repeated bunching of the gown material by the brace was solved by substituting 100% knitted structure fiber. The sleeve length can be adjusted with snaps on the sleeve cap and hem. When lifting up the gown for treatment on specific areas of the body, doctors open the edge of the right side of the gown in order to lift up the top. The bottom of the new patient gown was made from 100% cotton knitted structure fiber, and it enables patients to control the length of pants by attaching two snaps on the side. The results of an on-site dressing suitability evaluation and a flexibility evaluation with respect to dressing/undressing indicated that the new patient gown was much better received than the existing gowns (A and B). Our hypothesis regarding new patient gowns was supported in both the fit and design categories.

This study proposes the requirements for students in colleges majoring in fashion at two-year colleges in Seoul and Gyeonggi-do to perform behaviors in preparation for a further career more effectively by identifying the impact of social support on the career decision-making self-efficacy, and behaviors preparing a further career. The results of this study are described below. In accordance with the analysis on the relationship between career decision-making self-efficacy and behaviors preparing a further career, and the social support, the social support had a positive impact on the career decision-making self-efficacy and a negative impact on the behaviors preparing a further career. Moreover, the career decision-making self-efficacy had a positive impact on the behaviors preparing a further career. In accordance with the analysis, social support from family members or relevant third parties is required for improving the behavior of students majoring fashion in colleges to prepare a further career. To this end, the quantity or scope of social support is not the main issue, but the meticulous approach to fit each student's need for making students recognize such social support. It is important for students in colleges to enhance career decision-making self-efficacy by accurately identifying their abilities, values or desires.

The purpose of this study is to conduct an in-depth examination into the cause of stress as well as reasons for turnover relative to fashion industry workers in their 20s-30s, thereby seeking effective improvement methods to reduce turnover. The study method consisted of one-on-one in-depth interviews to collect data on 15 fashion industry workers. Results were as follow. First, causes of stress for fashion industry workers in their 20s-30s include work related factors, interpersonal relations, and organizational culture, while the most frequently mentioned reasons for turnover were concerns about career track and aptitude as well as annual salary, revealing that self-improvement related growth potential is the most significant factor for turnover. Second, it was not one stress factor that influenced turnover but a composite of several stress factors that motivated individuals to change jobs. Last, time flexibility, self-esteem, and development potential were critical factors for turnover. Self-esteem and development potential that provide a sense of acknowledgment were especially emphasized as the most significant, revealing that the younger generation considers personal happiness to be critical and the more this aspect is not treated adequately the more the odds of choosing turnover. To mitigate this issue, an in-house educational system for self-development and an assignment rotation system must be adopted for workers to change to positions that fit their aptitude.

The purpose of this study is to analyze external elements of 'time series table serving' and to discover any problems in the table setting. We selected two traditional Korean restaurants in five-star hotels and two representative traditional Korean style restaurants and analyzed the tableware arrangement of their table settings. The results are as follows. In restaurant A, the arrangement of different styles of tableware made from a variety of materials seemed relatively natural. However, the dessert plates were 'Buncheong' ware made with 'Bakji' method; in this case, the pattern was larger than the size of the fruits served and made the food inconspicuous. Rather than using plates made with a 'bakji' method, using plates with small patterns in the 'johwa' method would complement the food. In restaurant B, the space between the tableware, spoon and chopsticks was narrow, and the spoon and chopsticks sets would not fit on the table pads when large dishes or multiple dishes were served. In this case, changing the dishes to smaller sized dishes, considering the size of the table pad, or not using the pad at all would solve the issue. In restaurant C, too many small dishes were laid on the table, making it look disorderly. We believe that recovering tableware that is no longer in use, laying dishes and cutlery inside of the table pads or not using the table pad would be better. In restaurant D, the same style and color of dishes were provided 9 times. The lack of variety could be tedious to customers. The forms and colors of dishes should be changed in accordance with the order of the meal served. However, when using tableware created by different methods such as 'Buncheong' ware or white porcelain, the same pattern should be chosen in order to elevate the dignity of the table menu through uniformity. These issues in tableware arrangement indicate that external forms of banquet table setup should be studied so that the culture of Korean traditional cuisine can be enriched.
