This study was attempted to investigate the effects of enzymatic modification of milk protein with protease on functional properties. The selected functional properties were solubility, emulsifying activity (EA), emulsion stability(ES), foam expansion(FE), and foam stability(FS). These properties were measu-red from pH 3.0 to pH 8.0. The proteases used in this study were iaolated from Meju(fermemted soybean) and had specific activity of 250 units/㎎ protein at pH 7.0, 1600 units of pretense was used for 1gr. of skim milk protein. Skim milk showed 30.5％ degree of hydrolysis for 1 hr. and 36.4% degree of hydrolysis for 3.5 hrs. of protease treatment at pH 7.0. Solubility of native skim milk, control, 1 hr. and 3.5 hrs. groups were 3.37, 3.64, 10.21, 14.34％o at pH 4.0 respcetively. The emulsifying activity of native skim milk, control, 1 hr. and 3.5 hrs. groups were 38.8,42.0,43.0,46.7ft at pH 4.0, respectively. Enzymatic modification resulted in the increase of solubility and emulsifying activity at pH 4.0. However at pH 5.0 emulsifying activity of 1 hr. and 3.5 hr. group were lower than native skim milk and control groups. 1 hr. protease treatment was found to be most effective way of increasing foam expansion at pH 4.0 to 6.0. It was supported that, protease treated skim milk can be used to improve solubility, emulsifying activity, foam expansion at acid pH. meju protease. skim milk, solubility, emulsion, foam.

The individual differences in disease development and susceptibility have been researched primarily on the subject of genes, environment or the interaction between genes and the environment respectively. However, there have been limitations in explaining complex diseases, and the differences in health and diseases in monozygotic and dizygotic twins. Fortunately, thanks to active research on the relationship between genes and the environment, and epigenetics, there has been much progress in the understanding of body's reactions and changes. Epigenetics is referred to as a study of gene expression through the interactions of DNA methylation, chromatin's histone and the change of structure in tail, RNA editing without any change in DNA sequence. In this paper, we introduce the basic concepts and mechanisms of epigenetics. The result of the epigenetics is heritable ; can regulate gene expressions ; is reversible ; and has many variable forms depending on cell types. The influences of epigenetics occur throughout life, but it is mainly determined in utero during early pregnancies. Diseases occur or the risk rises if these influences continue after birth until adult life when problems occur in excess/lack of nutrition, environmental plasticity, or already inputted data. Therefore, there is a need for change and innovation, especially in interest and investment in health education for young women near pregnancies and correct treatment of epigenetic-related diseases.

Purpose: The purpose of this study was to describe perceived family support, life satisfaction, and health promoting behavior (HPB), and to identify factors influencing HPB among the elderly. Method: Study participants were 165 elderly over 65 years of age who were living in C city, Korea. The instruments included the Family Support Scale developed by Kang, Life Satisfaction Scale developed by Choi, Health Promoting Behavior Scale designed by Walker, et al. The data were analyzed using the SAS program by t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: 1. The scores for family support ranged from 11 to 55, with a mean score of 41.55. The scores for life satisfaction ranged from 0 to 40, with a mean of 22.02. The scores for HPB ranged from 40 to 160 with a mean score of 98.07. In the sub-dimensions of HPB, the participants showed the highest level of engagement in the nutrition domain, and the lowest level of engagement in the exercise domain. 2. Higher levels of family support and life satisfaction were correlated with more engagement in HPB. 3. The most influencing factor on HPB in the elderly was family support. accounting for 11% of the total variance in HPB. A combination of education level and types of living patterns accounted for 18% of the total variance in HPB. Life satisfaction accounted for 14% of the self-actualization domain, and 5% of the stress management domain, in the sub-dimensions of HPB. Conclusion: Perceived family support was identified as an important factor to predict HPB in the elderly. However, life satisfaction was identified as only partially influencing HPB among the elderly.

Purpose: The purpose of this study was to contribute children's health care and health promotion by surveying the use of visiting nurses in child day care centers. Methods: This study is a descriptive study, and the study period covers July to September, 2010. The research subjects were 27 public health center managers, 166 visiting nurses and 137child care teachers. Results: Teachers' need of visiting health care services and visiting nurses' work performance of were statistically significantly different. The teachers' need of visiting health care was higher in all areas (health examination, health life practice, infectious disease control, safety accidents and disaster management, emergency measures and linkage, nutrition, parent education) but the visiting nurses had a low level of work performance. Conclusion: Child care teachers are not health professionals for child health care, and therefore they are in need of professional help. Thus, for the current public health centers in need of customized visit health care, new visiting nurses in charge of professional child health care need to be developed. Also, new models need to be developed for visiting nurses and child care teachers through the connection of community child health care.

Objectives: The purpose of this study was to examine the cross-sectional relationship between low blood lead levels and increasing blood pressure among Korean adults using a nationally representative sample of the Korean population: the Korea National Health and Nutrition Examination Survey (KNHANES) 2008. Methods: A total of 918 subjects aged 40 and older and not currently being treated for hypertension participated in this study. Information about age, gender, smoking status, alcohol consumption, education level, and the use of anti-hypertensive medication was collected. The blood pressure was defined as the mean of the second and the third measurements after three time measurements. Lead levels were determined by an analysis of blood samples. Multiple linear and logistic regression analyses were implemented after adjusting for covariates including age, gender, educational level, smoking status, alcohol consumption, and BMI. Results: This study showed that the average differences in systolic and diastolic blood pressure comparing the lowest to highest quintile of blood lead were 4.33 mmHg (95% CI, 0.66-8.00; p for trend = 0.027) and 2.66 mmHg (95% CI, 0.26-5.06; p for trend = 0.021), respectively. After multivariate adjustment for covariates, the prevalence odds ratio (POR) of subjects in the highest quintile was associated with a 1.70-fold increase in the risks of hypertension (95% CI, 0.83-3.49; p for trend test = 0.112) over those in the lowest quintile of blood lead concentration, However, it was not statistically significant. Conclusions: This study provided evidence for an association between low- levels of blood lead and elevations in blood pressure and risk for hypertension in the general population of Korea.

It is expected that the typical lifestyle of the future will be transformed into an opulent and comfortable existence as the quality of life improves due to the increase in household income and reduction in working hours. In the meantime, as the standard of living becomes increasingly more comfortable and plentiful, the toll on physical health becomes magnified as a result of obesity and insufficient exercise caused by super nutrition and change in labor conditions. This has instigated a deep awareness in fitness on the part of many people, forcing them to recognize the significance of daily exercise and physical activity. The Elliptical Cross Trainer(ECT), which has drawn wide attention recently, is a non-impact athletic apparatus that not only promotes exercise of the upper body parts in such sports as skiing but also the exercise of lower parts of the body on a treadmill. It is a type of cross training athletic gear that has been developed for aerobic exercise throughout the entire body. It has already formed a market as big as that of the treadmill in Europe, America, etc. Recently, its demand is growing sharply in the Korean markets as well as those in Northeast Asian countries. Despite such demand increase and expansion, since most of the expensive ECTs are exclusively supplied by suppliers in only a few advanced countries, localization of the ECT is urgently required in order to enhance competitiveness of Korean manufacturers and to expand the market. The ECT development project has been in full swing for approximately two year since 2004 in order to secure independent design, as well as engineering and manufacturing processes in efforts to develop a commercially viable ECT.

The purpose of this study was to investigate the effects of eating habits and control of overeating of obese children on the body weight control program. The program included nutritional education, psychotherapy and physical exercise on weekly session for 9 months. The results of this study were as follows. Participants of the study involved 30 obese children attending elementary school. The average age of the children was 11.78 years, mean height and weight were 146.22cm and 50.61kg. The average BMI and body fat contents were 24.06 and 30.49% respectively and WHR of the children was 0.87. There was a significant difference between boys and girls' BMI(25.18, 23.31, p<0.01). As a result of the eating habits test, 50% of the subjects showed low level of regularity of diet, and 76.7% of the subjects showed high level of balanced diet score. Large portion(83.3%) of the subjects had high level of healthy behavior score. WHR of girls significantly decreased from 0.86 to 0.82(p<0.01) after the body weight control program. There were no significant differences in serum components of the obese children after the program. When regarding the score of eating habits in relation to obesity indices, the WHR significantly decreased(p<0.05) in a group of children with high eating habits score. Also in the group of overeating controls, significantly decreased WHR(p<0.05). In the results of correlation analysis, body weight was positively correlated with BMI(r=0.624), the level of total cholesterol(r=0.5109) and HDL cholesterol(r=0.5088). The score of healthy behavior was positively correlated with height(r=0.5286) and negatively correlated with the level of LDL cholesterol(r=0.3555) and WHR(r=0.4028) These results suggest that the body weight control program must be considerate of the different groups of children with different scores in the eating habits and overeating controls test.

The purpose of this study was to analyze employees' practice levels and knowledge of sanitation at school foodservice operations, to examine the sanitation conditions of current school foodservice, and to suggest an effective sanitary training program. A questionnaire survey was conducted on a total of 578 subjects and 501 reponses were made available for this study. The collected data was analyzed using SPSS of windows. The main results can be summarized as follows: Training through handouts was the most effective (53.2%) and lack of time caused by overwork (57.1%) made the practice of sanitation training difficult. The degree of employees' perceptions of the necessity of sanitary training programs was marked at 4.18 points. According to the foodservice employees' evaluation about the knowledge of sanitation concerning the sanitary training program contents, the area of environmental sanitation (96.3%) was the highest while food poisoning control (72.9%) was lowest. Foodservice employees' practice levels was ranked above 4 points (out of 5 points) in 9 areas. Practice levels of cleaning and disinfection management were highest while that of safety management was lowest. About the food service employees' practice levels of sanitation, the degree of practice and the application of knowledge was 4.39 points. There was a significantly positive correlation between the practice level of sanitation and sanitation knowledge(p<.01). Thus, educational material needs to be standardized in order to improve employees' sanitation practice level.
