This study was conducted to analyze aspects of women's skin care and related factors in order to contribute to community residents's right skin care. The subjects of this study was 800 women who were 15 to 65 years old. Data were collected in Daegu City and Kyungsan City from June 21, 2002 to August 18, 2002. The results of this study can be summarized as follows. 1. According to socio-demographic characteristics of the respondents, 26.8% of them were in twenties. 50.9% of them was students at colleges or graduated from collges. 38.3% was students and 37.5% was housewives. 55.5% belonged to the middle economic class. 2. 47.9% of the respondents replied that they were in good health. 57.2% of them had fair skin, while 25.1% had dark skin. According to health condition of face skin, 61.5% was in regular condition, while 26.0% was in bad condition. 29.9% had drying face skin and 21.3% had neutral or complex character of face skin. 3. Among the reasons they had trouble with face skin, the proportion of having the rough skin was highest (25.0%). 16.6% replied that they had trouble with a lot of wrinkles and 16.3% replied that they had trouble with dark face skin. 25.4% responded that their face skin was too tight. 13.3% replied that they had trouble with scars. 4. The factors significantly influencing the experience of skin care were age, education level, residence, experience of side effect of cosmetics, experience of skin diseases on face or body, experience of trouble after receiving skin care, and experience of trouble with acne. From above results, it can be concluded that selection of proper skin care rooms is important in receiving desirable skin care and preventing side effect related to skin care. The women also must be cautious in selecting and using cosmetics and massage pack. The government, related organizations, and skin and beauty specialists must make efforts to develop education programs for healthy skin care.

지금까지 전통음악분야의 현대적 구현은 민간 연주자들에 의하여 음악을 계승 발전시켜왔다. 특히 농악놀이에 현대적 해석을 가미한 사물놀이는 전통음악 현대화의 일등공신이다. 그러나 전통문화에 대한 공학적 분석은, 에밀레종의 맥놀이 분석[1], 징의 RIM깊이에 따른 음향의 변화[2] 등 다양한 분야에서 이루어지고 있으나, 전통문화와 IT의 융합은 접근하는 사례가 전무한 실정이다. 본 논문에서는 전통음악을 현대화시킨 사물놀이를 사물놀이 고유의 풍모를 살린 전통인형과 함께 임베디드 시스템으로 제작하고, 사물놀이 연주가 수록된 정간보를 디지털악보로 변환하여 악보 내용을 바탕으로 사물놀이 인형들이 각각 사물놀이 악기를 연주하여 사물놀이 본연의 조화를 이룰 수 있는 시스템을 구현하였다.

As part of perfluorocarbon (PFC) tracer release experiment conducted at the western coastal area of Korea in February 2001, the background concentration level of perfluorocarbons (PFCs) in the atmosphere was determined by gas chromatography with electron capture detector. Prior to the PFC tracer release experiment in the field, air samples were collected using active samplers and the background concentrations of PFCs were determined. The concentrations of perfluoromethylcyclohexane ($C_7F_{14}$, PMCH) in the western coastal area of Korea were in the range of 5.8-8.7 fL/L. The mean concentration of the PMCH in the region exhibited no significant spatial and temporal variations. This concentration level is somewhat higher and has larger standard deviation than those of studies previously conducted in USA and Europe on the background concentration levels of PFCs. Because the background concentration of PMCH in Korea is still very low and consistent temporally and spatially, the PMCH tracer can be used suitably for the studies of long-range atmospheric transport.

According to U.S. NTSB, from 1989 to 1992, Situation Awareness(SA) was a major factor causing 80% of all aircraft accidents in scheduled airlines. Therefore, the prevention of accidents through effective training in SA became a pivot in aviation safety. Furthermore, during the past 10 years, since all helicopter accidents in Korea were caused by the factors related to SA, an appropriate countermeasure has been required. This study, which uses survey data, examines various factors related to SA that could affect helicopter pilots. Common characteristics of situation awareness factors are that the result from the independent variables which are flight time, duty period and age of a first officer is statistically significant with the result from the independent variables of an instructor pilot`s. However, only experience is statistically significant independent variable for factors influencing decision making in emergency situations, but anxiety, expectation and comprehension are not significant.
