This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

조남준,구자경 한국기술교육대학교 2006 論文集 Vol.13 No.1

We have investigated the properties of oil-in-water microemulsions and nanoemulsions. The nanoemulsions are prepared with using a microfluidizer under 1,500bar and they showed decreasing droplet diameter upon repeating cycles in fluidizer up to six times. The microemulsions prepared with using a homogenizer exhibited the decrease in particle diameter with increasing surfactant HLB value, decreasing oil content and increasing surfactant/oil ratio. However, the diameters of nanoemulsions prepared with using a fluidizer, a high shear device, did not much depend on the HLB of surfactants and the oil content in water. The particle size of nanoemulsions prepared with 10% soybean oil converged around 110-125nm regardless of surfactant HLB values.

Occupancy of the T-cell receptor (TCR) by antigen in association with class Ⅱ MHC molecule is required for the initiation of T cell activation. However TCR stimulation is not a sufficient signal to account for all the observed events that occur during T cell activation. And in the absence of a second costimulatory signal provided by abtigen presenting cell antigen specific signal may lead to clonal inactivation or energy. CD28, a T cell surface molecule first defined by monoclonal antibody 9.3 on human cells, appears to function as an alternative, TCR/CD3-independent, activation pathway for T cell. This molecule provides costimulatory signal for T cell proliferation by increasing a number of lymphokines and cytokines production. A T cell activation antigen CTLA-4 is homologous to CD28 with 28% amino acid and 67% of nucleic acid homology in the protein coding region. CTLA-4 was ofiginally identified by the differential screening follosing subtractive hybridization of murine cytotoxic T cell cDNA library and mapped to the same lacation on chromosome 2 in human and chromosome 1 in mouse as CD28. These findings and activation associated expression pattern of CTLA-4 raise question about functional role of this molecule in T cell activation. In this study human CTLA-4 cDNA was amplified from phytohemagglutinin (PHA)-stimulated human peropheral blood lymphocytes mRNA by using reverse transcription-ploymerase chain reaction (RT-PCR) method. And amplified human CTLA-4 cDNA was subsequently cloned into pRC/CMV vector. In double stranded DNA sequencing the 331st base of protein coding region was changed from guanylic acid of human CTLA-4 from alanine to threonine. Murind L cell transfected with this clone expressed 36kD protein. It appears that this dirrerence of molecular weight between native (34kD) and recombinant (36kD) human CTLA-4 molecule may due to glycosylation differences. The cDNA and murine CTLA-4 molecule may due to glycosylation differences. The cDNA and murine L cell lines expressing human CTLA-4 developed by this study would contribute in future work unveiling the biological rile of CTLA-4 in T cell activation.

The purpose of this study was to investigate the storage and cooking of eggs in addition to the purchase of special eggs. This survey was carried out through questionnaire and subjects were 429 housewives whose children were middle or high school students in Kyunggi-do and Inchon. Most housewives began to purchase special eggs one year ago. When housewives purchased special eggs, the first consideration was in order of nutrition, freshness, price and preference. The higher housewives' education level was, the higher they took nutrition into consideration. More than half of housewives replied that the proper package of special eggs was 10 eggs or more, and perceived that the period between producers of eggs and consumers was less than 5 days. Most housewives did the freshness test by checking roughness of shell surface or the interior quality of egg yolk and white after purchase. Also most housewives stored eggs in the inside rack of refrigerator door. Most housewives served dishes made from eggs more than 2 or 3 times per week and perceived that soft-boiled eggs are foods easy of digestion. These results suggested that it is necessary to supply fresh and nutritious eggs and to develop various dishes made from eggs for quickly-prepared meals.

The purpose of this study was to analyze the effects of food habits on physique and body composition between obese and normal groups for suburban and urban girls, ages 9 and 15 years, living in Pusan and surrounding areas All data were collected on 159 suburban girls(80 for 9 years and 79 for 15 years) and 157 urban girls(80 for 9 years and 77 for 15 tears). Analyses are made between obese and normal groups for measures of physique(height and weight), body composition(skinfold thickness, Body Mass Index, % body fat, total body fat, lean body mass) and questionnaires(food habits and food preference). Statistical nanlysis of the collected data were analyzed in t0test, χ²-test and F-test using SPSS/PC package program with an alpha level of p<.05. The conclusions of the study are as follows ; 1. The differences in physique and body composition (1) Height, Weight,% body fat, total body fat and BMI were significantly higher in obese group than normal group(p<.001). 2. The differences in food habits (1) Irregular food habits in the obese group showed significantly higher than normal group(p<.001). (2) The period of absent meals for breakfast in obese group showed significantly higher than normal group(p<.001). (3) In the period of between meals, in case of 'between breakfast and lunch time' in obese group showed significantly higher than normal group(p<.05). 3. The effects influencing physique and body composition of food habits (1) Irregular food habits showed height, weight, body fat(p<.001), BMI, lean body mass(p<.01),% body fat(p<.05) significantly high in obese group, and physique and body composition showed significantly high in obese group, and physique and body composition showed significantly high(p<.001) in normal group. (2) The shorter the meal eating period were higher the height, weight, BMI(p<.01),% body fat, lean body mass(p<.05) significantly in obese group. (3) When they had between meals more than 3 times a day showed height, weight, lean body mass(p<.001) and body fat, BMI(p<.05) significantly high in normal group. and when they had between meals after supper showed lean body mass significantly high(p<.05) in obese group. In these results, the physique of girls were very rapidly increased and the percentage of body fat were also very increased recently. But it must be effected on the undesirable food habits. Therefore, the active efforts for girls in peak growth velocity are to be requested that they have to eat balanced diet regularly and have regular exercise habits.

Rotaviruses (Rv) are the major cause of severe dehydrating dearrhea among young children in Korea, where they are frequently responsible for 68% of the cases requiring hospitalization. Laboratory diagnosis of rotaviral infection in Korea depends mainly on enzyme-linked immunosorbent assay (ELISA) that employs expensive commercial diagnostic kits purchased from abroad and that shous the presence or absence of group A Rv only. PACE have however provided epidemiologic evidence to demonstrate the sxistence of different strains (both group A and atypical Rv) during diarrgeal outbreak, the appearance of new strains and desappearance of old ones from a community, shifts in the prenalence of strains, and the persistance of a single strain in newborns. For such reasons, we have felt that it is essential to raise the sensitivity and shorten the processing time for PAGE. We therfore have devised a rapid method for Rv RNA extration by directly extracting the Rv RNA from the specimens (that is, skipping freon extraction and running as ultracectrifuge) and using an urea-containing dissociation mixture to dissolve dried RNA for PAGE. We have also shorten the PAGE diagnostic results by sequential staining of the same gel with ethidium bromide and silver stain. With the use of the rapid method, it was feasible to increase the efficacy of the PAGE with reduced cost and working time. Phenol extration of stools, however, was essential in maintaining the sensitivity of the method.

This study was undertaken to investigate the relationship between the food habits and the health status. For this purpose, data were collected from deep interviews with 124 the elderly women and men, age 65 or greater in Pusan, Korea. For the data analysis, percentages, frequencies and means were calculated in order to describe the data. t-test, ANOVA, χ²-test were used. As a result of the data anylsis, the following results were obtained : 1. The age about the object person of research was the most numerous in 79% at 65-74 years old, in 70.9% with any their children, most elderly women and men were without job, regular excercise, regular health check and regular income. 2. The average man's weight was 61.89±6.33kg, woman's weight was 52.75±4.42kg, the average man's height was 166.47±7.92cm, woman's height was 154.96±6.02cm. 3. Both of the elderly men and women had regular meals at breakfast, lunch and supper. The most delicious meal was supper. The style of food intake was vegetables or mixed with vegetables and meats. Eventhough the participating at eating out with family was low, having meals with family at home usually. The problem of food habits was too much salty. 4. Eventhough both of the elderly men and women had eating some snacks between meals, they didn't have any nutritious reasons. Usually their child supplied it and in case of spouse, only the elderly women had the charge. 5. The elderly men were higher than the elderly women in case of smoking and drinking. 6. The elderly men wee better score than the elderly women with food habits. 7. Most of the elderly men and women had any chronic illness. 8. The elderly men were higher score with most areas except respiratory organs, the elderly women were score than the elderly men in the state of health. 9. The relationship between the elderly men and women showed a meaningful difference, fatigue showed a symptom as physical health, and nervousness showed a symptom as mental health with having poor food habits. The chronic illness also connected with poor food habits.
