The purpose of this study was to estimate the urinary excretion of sodium cho\ulcornerloride of adolescent in Jeon Bug. Korea and to evaluate the correlation of sodium chloride excretion by sex and area. The subjects were 261 healthy persons of 16 years old ( male 131. fermale 130) which were randomly choosen from different areas (city, farming area and fishing area). The urinary sodium chloride excretion in 24hrs were evaluated. which were cal\ulcornerculated from the analysis of urine sample gathered for 12hrs. The results were as follows; 1) The urinary excretion of sodium chloride by the group of male and female in 24hrs were 388.0$\pm$191.4mEq(22.68$\pm$l1.19gm) and 303.6\ulcorner138.0mEq(l7.75$\pm$8.07gm) reo spectively. 2) The urinary excretion of sodium chloride by the group of male was higher than by the group of female. 3) The urinary excretion of sodium chloride by the group of city, farming area and fishing area in 24hrs. were 256.2$\pm$96.8mEq(14.97$\pm$5.66 gm), 433.2$\pm$188.6 mEq (25.32$\pm$l1.62gm) and 356.0$\pm$169.8mEq (20.81$\pm$.92gm) respectively. 4) The urinary excretion of sodium chloride by the farming area group and the fishing area group were higher than the city group. Hence the daily urinary excretion of sodium chloride by adolescent of 16years old was estimated to be 20.21$\pm$9.63gm.

This study was devised to elucidate whether soused shrimp exhibits a digestive action on boiled pork meats. and the mechanism by which sousing with a high concentration of sodium chloride preserves nutrients in foods for a prolonged pe\ulcornerriod. Protease was isolated from soused shrimp using a combination of ammonium sulfate fractionation. DEAE - cellulose ion exchange chromatography and gel filtra\ulcornertion. The isolated protease had specific activity of 1.560 units. 210 purification fo\ulcornerld with an yield of 38%. Its optimum pH and temperature were 8.0 and $43^{\circ}C$ respectively. The molecular weight of the enzyme was 35.000. The Km value of the enzyme for casein was 1.6 x $10^{-6}$ M The e=yme required the presence of cu\ulcornerpric ion to exhibit its full activity. Eighty eight percent of the enzyme activity was in\ulcornerhibited by 3.5M NaCI showing a reversibly linear decrease of the enzyme activity as NaCI concentration increased. The nature of the inhibition by NaCl was rever\ulcornersible and noncompetitive. The protease activity in soused shrimp was well preser\ulcornerved with the elapse of time at least in part due to NaCI induced suppression of autodigestion. The enzyme was denatured by acid easily. i.e. 1% of the original activity remained after staying at pH 2 for 10 minutes. which is within the norm\ulcorneral range of pH of the human stomach. Soused shrimp was observed to be one of those containing the highest protease activity compared with the other soused foo\ulcornerds such as soused oyster. squid. clam. and Pollack intestine with respect to spec\ulcornerific activities of dialized 1:4 whole homogenates(w/v) in 5 mM sodium phospha\ulcornerte - 2.4 mM j3 - mercaptoethanol buffer. pH 8.0. Casein and boiled meats including pork, beef, and chicken appeared to be the good substrates for the protease. Casein was the best. Therefore. the ingestion of boiled meats including pork together with soused sh\ulcornerrimp would help digestion of boiled pork in human not only by increasing appe\ulcornertite also by the direct proteolytic digestion of boiled meats by soused shrimp to\ulcorner some extent. And a high concentration of sodium chloride inhibited the protease activity reversibly in a remarkable degree, which ensued in a significant retardat\ulcornerion of autodigestion of protein in foods by proteases, and hereby contributed to the preservation of foods for an extended period.

CCK ( Cholecystokinin)와 carbachol (carbamylchline chloride)이 췌장의 효소분비능력을 촉진시킨다는 사실은 잘 알려져있다. 생대두식이를 먹인 쥐에서 췌장세포의 hypertrophy 현상이 두드러지게 나타나고 소화효소의 과다분비 현상이 나타나므로 이번 실험에서는 익힌 대두와 생대두를 먹인 후 정상적인 췌장세포와 hypertrophy 가 일어난 췌장세포에 CCK 와 carbachol 로 자극을 준후 효소분비 능력을 비교하였다. 췌장세포에서 분해되는 단백질 분해효소들이 세포자체에 미치는 영향을 최소한으로 줄이기 위하여 췌장의 acinar cell을 분리한 후 cell column을 만들어 superfusion technique 에 의해 stimulus-enzyme secretion coupling 방법을 사용하였다. 분리한 췌장세포를 CCK와 carbachol 로 자극을 주었을대 chymotrysin 분비는 생대두를 먹인 쥐의 세포에서 익힌 대두를 먹인 군보다 높게 나타났고 amylase의 분비는 chymotrypsin 과는 달리 익힌 대두를 먹인 쥐의 세포에서 생대두를 먹인 군보다 높게 나타났다. 이번 실험의 결과는 지금까지 논쟁중에 있는 췌장의 acinar cell에서의 여러 가지 효소분비 비율은 항상 일정한 것이 아니라 자극의 종류에 따라 효소분비량의 구성비율이 달라진다는 것을 알려주고 있다.

This survey was carried out to study the relationship between observable factor such as anthropometry, blood pressure, food habit, the score of THI and diseases of 459 persons (male: 188, female: 271) aged 60 and over in the rural area of Kurye - Gun Chonnam from April 28 to May 1, 1986. The results obtained were as follo\ulcornerws 1) Body weight and height was below Korean average. The mean obesity rate in male and female showed -2.3% and 3.4%, respectively, and BMI showed 25.8 and 26.0 respectively. 2) The systolic and diastolic blood pressure was normal in both sexes. The pro opotion of hypertension by WHO level showed 19.6% and 20.3% in male and fem\ulcornerale, respectively_ The proportion of anemia showed 57.9% and 41.7% in male and female, respectively. The concentration of total protein, albumin, cholesterol and gl\ulcornerucose and white blood cell number showed normal range in both sexes. 3) The proportion of the disease showed 68% of male and 83% of female and among them 50% of male and 43% of female suffered from one kind of disease and there are more female who suffered from many kinds of diseases than male. The most common disease is neuralgia and nexts are digestive diseases, diabetes melli\ulcornertus, urinary disturbance, motion disturbance, arthritis, respiratory diseases, tubecu\ulcornerlosis and hepatitis. 4) There was a significant correlation between body height and weight and the score of food habit. 5) There was a considerable relation between the score of each item of TIll and the status of diseases. 6) There appeared profound relation between obesity rate and the data of anth\ulcornerropometry, but weak relation between that and blood constituents, and no relation between that and the score of food habit.

Various types of restaurants in Seoul city are a were assessed in terms of facilities equipped, and dining and kitchen space allocation. Facilities checklist was developed to evaluate the facilities condition of sampled restaurants. Subjective sample were randomly selected based on the distribution factors of areas, types and sizes. The facilities for the sanitary working environment were assessed as the insufficient condition. Also basic kitchen equipments and facilities, and restroom facitilities of restaurants were within the kitchen or dining room space allowance level. Space requirement and facilities standard models were developed for the guideline to improve the working environment.

Since diet is an essential component of the treatment for diabetic mellitus, a progressive educational plan was designed to educate diabetic children for the proper selection of their foods. Seven suspicious children were chosen according to the previous oral glucose tolerance test and present blood glucose levels (fasting and postprandial 2 hours). The education program includes the basic nutrition study, learning of the five basic food groups. familiarization with the food exchange lists. calorie calculation and menu planning, and follow-up evaluation by checking every day -food intake. The duration of the education was five weeks. The levels of fasting blood glucose and postprandial -2 hours blood sugar of the seven children were significantly reduced after the 5-weeks education:FBS:from 92-125mg% to 67-80mg%, pp-2hours BS: from 130-169mg% to 69-90mg%. The children have felt much better with profound self-confidence after to program . Their oral glucose tolerance test levels were also significantly decreased after the 5-weeks education in comparison with those of one year ago.

Prevalence of obesity and dietary consumption of ten-year-old school children in Seoul were investigated. Three hundred forty boys and three hundred forty two girls from families of various housing pattern in Seoul were chosen for this study. Informations of the stduy were obtained from April 22 to June 11, 1985, by means of prepared questinnaires for general environmental factors, anthropometry for height, weigth and triceps skinfold theickness and interview to get 24 -hour food intakes of individuals. All the data collected were analyzed by using SPSS program. Average nutrients intakes of the subjects were satisfactory with respect toquality or quantity . Children from A group tended to consume more nutrients than B or C group. Physical growth of the subjects were similar to the ones for average school children in Seoul, but greater than korean national average. Children from A group were taller and heavier than B group whom were taller and heavier than C group . Prevalence of obesity were 15.7 % and 11.7 % of the subjects according to standards of relative body weight and triceps skinfold thickness. Higher prevalence were observed in boys than in girls and children from A group than B, and B group than C group. so therefore it could be summarized that children from A group consumed more nutrients, had better physical growth, and became obese more frequently than children from B or C.

This survey was carried out to investigate the effect of taking a nutrition course on the nutrition knowledge and food habits of college students who do not major nutrition. Questionnaires were completed by 444 students who have taken nutrition course and by 555 students who did not take nutrition course. Nutrition knowledge score of the students taken nutrition course was significantly higher than that of students did not take nutrition course(p<0.001). Especially male student obtained lower nutrition knowledge score than female students in graups who did not take nutrition course (p<0.001), but there was no difference in nutrition knowledge score between male and female students who have taken nutrition course. The students taken nutrition course showed higher food habits score than those who did not take nutrition course (p<0.001). The former had a lower response rate than that of the latter, for what are regarded as poor food habits. There was a significant and positive correlation between nutrition knowledge score and food habits score in students who have taken nutrition course but not significant correlation in those who did not take nutrition course.
