대구지역 남자 대학생의 체중조절지향 및 체형에 따른 식습관 및 기호도, 영양지식을 조사하기 위하여 대구 C대 남학생 219명을 대상으로 설문지 및 신체계측을 통하여 조사한 결과는 다음과 같다. 1. 조사대상자의 평균연령은 19.8±2.3세였으며, 평균 신장 및 체중은 173.8±8.7cm 와 65.8±7.9Kg, 그리고 평균 BMI는 21.9±2.4로 한국인 체위기준치의 표준신장 172.0cm, 체중 66Kg, 평균 BMI 22.3과 비슷한 수준이었다. 조사대상자들이 생각하는 이상적인 신장과 체중은 179.3cm와 70.4Kg로 이는 대체로 실제보다 큰 체형이었으며 이때 BMI는 21.9였다. 2. 스스로 평가한 자신의 체형은 '보통이다' 혹은 '여위었다'라고 생각하는 대상자는 72.7%였으며. 이상적으로 생각하는 체형은 '약간 살찜'이라고 답하였다. 체중조절에 대한 관심은 '좀 더 살찌기를 원함'이라고 답한 대상자가 74명으로 전체의 33.8%였고, '여위기를 바람'이라고 답한 대상자는 47명으로 전체의 21.5%였으며, '지금의 상태에 만족함'이라고 답한 대상자는 98명으로 44.7%였다. 3. 평소 식사량은 많은 편으로 '먹을 수 있는 최대의 양을 먹는다'고 답한 수는 전체 조사대상자의 40.6%였으며 체중군별로는 과체중군이 48%로 가장 높았다. 각 체중군이 가장 중점을 두고 식사를 하는 시간은 '저녁식사'였다. 식사의 규칙성은 전체 조사대상자의 51.6%가 '아침'을 규칙적으로 먹는다고 답하였으며 저체중군은 점심을 불규칙적으로 하는 것으로 조사되었다(51.1%). 식사를 거르는 이유는 '시간이 부족해서'라고 전체 조사대상자의 60.3%가 답하였으며 과체중군에서 '습관적으로 식사를 거른다'가 다른 군보다 높게 나타났다. 자신의 식생활에서 가장 문제가 되는 것은 '불규칙한 식사시간'이라고 조사 대상자의 45.2%가 답하였다. 4. 영양관련 정보를 습득하는 경로는 조사 대상자의 49.8%가 '신문이나 잡지, TV'라고 답하였으며 '부모님', '학교수업' 및 '영양관련 서적' 등 이었다. 반면에 '영양관련 지식의 습득이 전혀 없다'라고 대답한 조사대상자도 26.5%나 되었다. 식품군별 섭취빈도조사 결과 '저체중군'은 '육류'의 섭취빈도가 높은 반면 '과체중군'은 '채소'의 섭취빈도가 높게 나타났다. 5. 영양관련 지식에 대해서는 각 체중군은 20점 만점에 평균 15점을 기록하였다. 이들 체중군 사이에는 유의적인 차이가 없었으며 조사 대상사의 연령이 증가함에 따라 영양관련 지식은 상대적으로 감소하였다(p〈0.05). 6. 체형에 따른 식품섭취빈도는 일반적으로 '곡류 및 면류'를 가장 선호하였으며, '야채류 와 '기호식품 및 간식류'의 선호도도 높은 편이었고 '햄, 소세지'에 대한 선호도는 모든 체중군에서 낮게 나타났다. '김치'의 섭취빈도가 각 체형군에서 고르게 가장 자주 섭취하였다. '과체중군'은 다른 군에 비해 '쇠고기'와 '기호식품 및 간식류'의 섭취빈도가 낮아 유의적인 차이를 보였다(p〈0.01). 저체중군'은 '과체중군'에 비해 육류의 섭취빈도가 높은 반면 '과체중군'은 야채와 과일 섭취빈도가 높았다. 이상의 결과로 남학생의 체형에 대한 올바른 인식과 이에 따른 식사행동이나 식습관의 바람직한 방향을 위하여 영양학의 이해나 영양교육이 필요할 것으로 사료된다.

To investigate the drinking pattern and behaviors of Yangsan College students, a self-administrated survey was conducted to the subjects, composed of male 336 and female 165. The results of this study were as follows: 1. With regards to kind of alcoholic beverage, 71.6% of subjects responds have a preference for soju, which is favored more by male than by female. 2. The most favorite side dishes are stew and soup(48.2%), then roasted meats and fruits. 3. In the drinking habit, 40.4% of subjects responded that they drink themselves to sleep, 20.6% have more chatter, and 12.5% become silent. 4. 80% of the subjects, some of which recognized overdrinking, responded that the culture to have a drinking after official events is essential, while 6.6% responded that it goes wrong.

This study was undertaken to assess eating out behavior and factors in food choices of 369 college students in Kwangju. 47.1% of subjects ate out at least once a day and lunch was the most frequent meal for eating out. Eating out expenditure was significantly associated with student's allowances. Significant differences were observed in frequency, expenditure of eating out and related factors in food preference between male and female students. Taste was the most considered factor but nutrition was the least considered in food selection of respondents. Among male respondents, the most important nutritive factor was protein followed by calorie and vitamin. However, female counterpart regarded calorie as the most important nutritive factor affecting food selection. Tendency of increased vegetable and fruit consumption was noted in subjects over past a few years. It might be suggested that effective nutrition education for college students be implemented to improve and develop eating out behavior related to nutrition in food selection.

We have improved the control and driving system of 16' reflector at Kwanak Observatory at Seoul National University, by completing encoder unit, and by developing programs for correction of errors resulting from hardware defects. The hardware defects of this telescope system are the large backlash and the nonuniform tracking and pointing. The telescope pointing accuracy for RA is improved to a few arc minutes, and that for DEC is several tens of arc minutes. The guiding error is improved to 0.7 arcsec/minute, allowing up to 3 minutes exposure for CCD imaging under typical seeing conditions at the Observatory.

We have carried out measurements of 1.2-1.6GHz radio interferences around Seoul Radio Astronomy Observatory located in the campus of Seoul National University. We received interference signals using a pyramidal horn antenna and measured its power using a spectrum analyzer with 1MHz resolution after ~60dB amplification. In order to check the spatial characteristics, we made observations at every 30∘ 30∘ in azimuth at elevation of 30∘and60∘ 30∘and60∘ . Also, in order to check the temporal characteristics, we repeated the all-sky observations five times at every six hours. The results may be summarized as follows: (1) There are strong (≥−20dBm) (≥−20dBm) interferences between 1.2 and 1.4GHz. Particularly strong interferences are observed at 1.271 and 1.281GHz, which have maximum powers of -0.34dBm and -0.56dBm, respectively. (2) The characteristics of the interferences do not depend strongly on directions, although the interferences are in general weak at high elevation and in east-west direction. (3) The interferences appear for a very short (≤0.01s) (≤0.01s) period of time, so that the average power is much smaller than the maximum power. Strong interferences with large (≤−49.0dBm) (≤−49.0dBm) average power have been observed at 1.271, 1.281, 1.339, and 1.576GHz. At these frequencies, the interferences appear repeatedly with a period of ≤0.1s ≤0.1s By analyzing the observed power, we find that, for the strongest 1.271GHz interference, the average intensity is −171dBW/m2/Hz −171dBW/m2/Hz and that the maximum intensity is −122dBW/m2/Hz −122dBW/m2/Hz . If this interference is delivered to the detector without any shielding, then its power would be much greater than the rms noise of a typical line spectrum. Therefore, it is important to shield all the parts of receiver carefully from radio interferences. Also, without appropriate shielding, the sensitivity of a receiver could be limited by the interference.

The issue of health and nutritional wellbeing becomes one of the utmost concerns for the welfare of the elderly in a society of increased aging populations. This study was conducted to assess nutritional state and to identify possible dietary factors that might influence health and nutritional state of the free living elderly women. Two hundred sixty two elderly women, aged 60-90 who are actively participating in a continuing education program for the elderly in Seoul area, were interviewed using a dietary habit questionnaire and a 24-hour recall. Anthropometric measurements such as heights, weights, body mass index, and tricep skinfolds and dental status were significantly different between the two age groups, 〈75 and ≥ 75 years of age. Sixty eight percent of the subjects were using nutritional supplements regularly, in the descending order of vitamin-mineral supplements(40%), botanicals(27.6%), tonic drinks(16%), and health foods(13.2%). For hot beverages, our study subjects drank coffee (33.6%) and green tea (17.9%) frequently, followed by doongulae, job's tears, citron and kyulmyung tea. With regard to micronutrients, vitamin C intake was found to be lower in the group aged over 75 compared to that below 75 (p〈0.05). Calcium intake was significantly higher among the elderly with good dental status followed by the groups with gingivitis, denture, and missed teeth with poor chewing abilities (p〈0.05). The amount of personal spending money was found to be a significant contributing factor (p〈0.05) to the energy and nutrient intake in an individual. The results of the present study can be applied to the identification of the possible factors that might intervene the aging process, to the planning of the nutrition education program, and to the development of health food products for the promotion of health and nutrition of the elderly women.

The purpose of this study is to investigate the drinking patterns and behaviors of Yangsan College students. Data were collected by a self-administered survey from the subjects, of which male students were 336 and female 165. The results of this study were as follows: 1. With regard to attitude toward drinking, 93.1% of the male subjects and 84.3% female subjects reported to have favor for drinking while only 9.3% of the subjects against drinking. 2. Those who reported to have at least a drink everyday were 13.3% of the subjects. For drinking frequency subjects who reported once in two or three day were most popular(21.9%). The frequency of drinking alcohol was associated positively with amount of discretionary money the students have. 3. For amount of drinking, 42.5% of subjects responded that they were able to drink soju at least one bottle per occasion. Data showed a high positive correlation between drinking frequency and financial costs they spent to drink. 4. The reasons subjects gave to drink included social gatherings after school or student activities (40.1%), change of mood(16.5%), and personal cerebration(16.5%). 5. The most popular place for the subject to go for a drink was neighborhood pubs(43.5%), followed by bar or pubs at downtown(28.3%) and nearby campus(12.2%).

A survey was conducted in 591 college students using 8 different cafeterias serving 31 meals. The information was obtained about the name and amount of dishes they consumed from the menu offered by college foodservice. Mean nutrient contents per meal in offered menu were higher than 1/3 of RDA for their age, sex in offered menu. The mean energy content was 466kcal from rice, 113kcal from soup, 141kcal from side dish and 21kcal from kimchi. When side dishes were classified by cooking methods, side dishes using grilling, frying, roasting methods had high energy content and fat percent above 200kcal, 40% per dish. By main ingredients, side dishes with animal food were higher energy than with plant food. Students consumed 94% of the energy provided in offered menu. When compared to proportion of foods consumed by sex, there was 43% of female and 22% of male consumed less than half in soup and 31% of female and 12% of male in kimchi. The most prevalent menu patterns of subjects included rice, soup, 2 side dishes, kimchi and were the same in both sexes. Mean energy intakes per meal were 989kcal for males and 842kcal for females which were enough to meet 1/3 of RDA for their age and sex. Most nutrient intake except fat and vitamin B1 were higher in set menu than in cafeteria. Nutrient adequacy ratio(NAR) were above 0.9 except calcium and vitamin A. The mean energy intake was 542kcal from rice, 70kcal from soup, 164kcal from side dish and 20kcal from kimchi. In conclusion, intake of most of the nutrients of students obtained from males in college foodservice were sufficient but calcium intake was insufficient and fat content was above 20% of energy. High fat consumption was due to side dishes from frying, grilling, roasting with animal food. To provide desirable meals in college foodservice, use of fat in cooking must be decreased.
