The purpose of this study was to analyze the satisfaction level on hospital foods in elderly and middle aged patients. The subjects were selected among the patients treated in the Inha University hospital during July of 1999. One hundred thirty five elderly patients aged over sixty(68 men, 67 women) and sixty five patients aged in forties(35 men, 30 women) were surveyed through questionnaires in terms of satisfaction level on hospital foods and the food preferences. Satisfaction on general taste, saltiness, serving temperature, appearance, texture and variety of hospital foods was not significantly different according to age. However, elderly men showed significantly higher satisfaction level than elderly women in terms of general taste of hospital foods(p<0.01). The preferences of cooking method for meat, fish, vegetable and the preferred kinds of kimchi and milk & milk products were not significantly different between the two age groups. However, elderly women significantly preferred sauted meat to broiled meat compared to elderly men(p<0.05).

The purpose of this study was to investigate the effects of resting periods between exercise sets during isokinetic contraction on recovery from muscle fatigue, strength, heart rate, blood pressure, and lactate level. Sixteen women performed 10 repetitions of isokinetic exercise for three sets in three different conditions. During the sets, they rested 50, 100, and 150 seconds in each condition. And the results were: 1) In this population, the peak torque of extensor during the isokinetic exercise in 100 second resting condition was significantly higher than that in 50 and 150 second resting conditions (p<.01). The total work of extensor was significant in the second and third sets in 50 and 100 second resting conditions (p<.01). 2) During the isokinetic exercise, the heart rate was progressively increased as the sets were advanced in all resting conditions (p<.01). And the increase was significant during the second and third sets than the first in 50 second resting condition (p<.01), while it was significantly greater after the third set than the first in 100 and 150 second resting conditions (p<.01). 4) No difference was found between the resting periods in blood lactate level and blood pressure during the isokinetic exercise. However, differences were found between the sets in these variables (p<.01).

Purpose of this study was to investigate the health status and life style of middle-aged people in Daejon. The subjects expressed more fear for disease as getting older(p<0.01). Sixty six percent of the subjects have suffered in the past or suffer at present certain kinds of disease. The older they are, the more disease they have. The alimentary disease, neuralgia, and arthritis were the most popular disease. The eye strain and exhaustion of body were indicated more frequently in fifties than in thirties or forties(p<0.01). They considered excercise as the most important factor to maintain health status, and then moderation in diet, relaxation, rest, decrease of alcohol intake, no smoking. Forty three percent of them were non-drinker. The number of drinker was four times more in male than female and increased as getting younger(p<0.01). Only male revealed smoker and 29% of them smoked 10-20 cigarettes per day. The number of smoker decreased as getting older(p<0.01). Male played exercise more regularly than female and subjects have better exercise habit as getting older(p<0.01). This study suggests that practical programs for self-health control should be developed for playing exercise regularly for female and for considering nutrition, no smoking, and no drinking in the daily life for male.

Benzoylphenylurea계 살충제(BPUs)는 많은 종의 곤충에 불임을 유발하는 것으로 알려져 있다. 이전의 실험결과 집파리의 불임에 효과적인 것으로 밝혀진 4가지 BPUs의 발육단계가 다른 집파리 성충에 대한 불임효과를 실험하였다. 수컷 성충 및 우화 후 교미하기 전의 암컷(우화 1일 후)과 교미 후 난소가 충분히 발육한 상태의 암컷(우화 5일 후)을 300 ppm의 약제에 24시간 동안 접촉시킨 후 1~2일 간격으로 채란하여 부화율을 조사하였다. Flufenoxuron과 teflubenzuron에 처리된 5일 암컷이 처리 1일 후 산란한 알은 전혀 부화하지 못하였고, triflumuron과 diflubenzuron에 처리한 5일 암컷이 산란한 알의 부화율을 23%로 크게 감소하였다. Flufenoxuron에 처리된 1일 파리가 처음 산란한 알은 es지 1%의 부화율을 보였다. 따라서 본 실험에서 사용한 4가지 BPUs계 살충제는 집파리 성충의 연령에 관계없이 산란된 알의 부화를 억제할 수 있었으며, 부화한 유충의 일부는 번데기까지 자라지 못하고 사망하였다. 실험에 사용한 4약제 중에서 flufenoxuron의 부화억제 효과가 가장 우수하였으며, 약효가 5일간 지속되었다.

Compared to last decade, body size of children has been changed because of many factors such as caloric intake, hereditary evolution, individual exercise, and so on. Naturally, children will grow up and they will become teenagers, college students as time goes by. Also, all children will enter into appropriate educational institutes according to age. The objective of this study is to compare and analyze the data of body size of children for safe educational environment. The data are measured by some parts on body such as stature, height, weight, circumferences, length, width, and depth. The samples for this study are randomly chosen from kindergartens in. Seoul and Kangnung during three months (2000. 3 ∼ 2000. 5).

The purpose of this study is to investigate the patterns of Korean traditional food use in the households of middle aged women living in Kyunggido and Incheon area Four hundred eighty seven housewives whose children were in middle school answered the questionnaire about Korean traditional food use patterns in ordinary days, national festive days and in private celebration or memorial days. Most households have used Korean traditional table setting called Bansang as daily meals(96.7%) and have used home-made Kimchi(97.3%). However, the use of home-made Jang such as soy sauce, soybean paste and red pepper soybean paste was not very high(64.3%). Most households have celebrated New Years day(99.6%) with Ddukguk and Manduguk, Chusuk(95.1%) with Songpyun, and fruits, Full-Moon day(95.1%) with Ogokbap, Namul and Brum. Dongji was celebrated with Patjug by 73.3% of households. However, Samjitnal and Danho were celebrated with Whajeon and Ssukjulpyun by only 18.9% and 43.8% of the households respectively. The households using Korean traditional food to celebrate the birthday, the 1st birthday of child, the wedding or to memorize the passing day of ancestors were 96.0%, 80.7%, 81.3% and 86.7% respectively. Compared to households of urban and nuclear family, households of rural and extended family tended to use significantly more Korean traditional foods in many occasions and showed significantly higher rate of using home-made Kimchi and Jang.

This nutritional survey was conducted from February 8 to March 10, 1994, in order to investigate the nutritional knowledge, food habits, nutritional attitude, food preferences and nutrient intakes of urban middle-aged women living in Daegu and Pohang district. The subjects of this survey were 164 urban middle-aged women living in Daegu and Pohang Area. The completely answered questionnaires were analyzed for nutritional knowledge, food habits, nutritional attitude, food preference and nutrient intakes of urban middle-aged women. The results obtained are summarized as follows: The subjects had a high level of perceived knowledge (82.9%), that is the knowledge that each subject believed she had, but the accuracy of the knowledge was only 66.1%. The average nutrition knowledge score was 8.26 out of possible 15 points, and food habit score was 5.50 out of 10 points. Most of the subjects belonged to 'Fair' or 'Good' food habit group, which is considered to be relatively good. With increasing age, the percentage of perceived knowledge, accuracy, and nutrition knowledge score were getting lower. But food habit score and nutritional attitude score were getting higher at 40's women than 30's women. The correlation between nutritional knowledge score and food habit score was low (r=0.0748). The correlation between nutritional attitude score and food habit score was low, too (r=-0.0653). Food preferences for kimchi, potato, cooked rice, beef, noodle, cabbage and milk were high. Average calorie and protein intake of the subjects were 1967.4±27.8 Kcal, 75.8±1.4 g respectively. Carbohydrate, protein and fat ratio on energy composition was 63.3%:15.5%:21.2%.

항공기용 고력 AI합금인 7075 AI합금의 물성개선을 위한 가공열처리 방안으로서 과시효처리후 온간 및 냉간 압연에 의한 소성가공이 재결정조직과 강도에 미치는 영향에 대하여 연구하였다. 소송가공후 재결정처리에 의해 결정립을 미세화하는 공정에서 소성가공 전 과시효를 함으로써 재결정립의 미세화 정도는 더욱 현저하였다. 이는 과시효에 의한 조대한 석출물이 재결정처리시 핵생성 site로서 작용하였음을 의미한다. 본 연구에서 항복강도와 재결정립의 크기와는 Hall-petch식을 만족하지 않았으며 이는 등축이 아닌 연신된 결정조직에 기인된 결과로 보이며, 항복강도가 재결정립의 종횡비에 직선적으로 비례하였다. 또한 결정립 미세화를 통한 강도, 인성향상을 목적으로 하는 TMT(Thermo mechanical Treatment)공정에서는 심한 냉간가공에 의해서보다는 온간에서의 소성가공이 바람직함을 알 수 있었다.
