The rotavirus-induced diarrhea of human and animal neonates is a major public health concern worldwide. Until recently, no effective therapy is available to specifically inactivate the rotavirion particles within the gut. Passive immunotherapy by oral administration of chicken egg yolk antibody (IgY) has emerged of late as a fresh alternative strategy to control infectious diseases of the alimentary tract and has been applied in the treatment of diarrhea due to rotavirus infection. The purpose of this concise review is to evaluate evidence on the properties and performance of anti-rotavirus immunoglobulin Y (IgY) for prevention and treatment of rotavirus diarrhea in human and animal neonates. A survey of relevant anti-rotavirus IgY basic studies and clinical trials among neonatal animals (since 1994-2015) and humans (since 1982-2015) have been reviewed and briefly summarized. Our analysis of a number of rotavirus investigations involving animal and human clinical trials revealed that anti-rotavirus IgY significantly reduced the severity of clinical manifestation of diarrhea among IgY-treated subjects relative to a corresponding control or placebo group. The accumulated information as a whole depicts oral IgY to be a safe and efficacious option for treatment of rotavirus diarrhea in neonates. There is however a clear need for more randomized, placebo controlled and double-blind trials with bigger sample size to further solidify and confirm claims of efficacy and safety in controlling diarrhea caused by rotavirus infection especially among human infants with health issues such as low birth weights or compromised immunity in whom it is most needed.

The purpose of this study was to identify job frequency and the training needs of dieticians in elderly health care facilities. This study consisted of dieticians working in elderly health care facilities with a capacity of over 50 elderly. Survey questionnaires were distributed to 190 dieticians through the mail and 106 dieticians (55.8%) participated in this study. The results of the survey showed that dieticians in elderly health care facilities frequently performed the following job: work management, safety and sanitation management, purchase management, human resource management, finance management, nutrition management, and marketing management. The job frequency in safety and sanitation management (p<0.05) and nutrition management (p<0.01) areas were significantly different by the number of dieticians. Safety and sanitation management and menu management were considered job areas that needed further training and education. Dieticians in elderly health care facilities responded that the following jobs should require not only training but are also frequently performed: safety and sanitation management, menu management, work management, and human resource management. Thus, based on the results of this study, continuous training programs in these fields should be offered to satisfy the needs of dieticians.

The purpose of this study was to compare differences in role conflict, self efficacy, job satisfaction, and job involvement perceived by school nutrition teachers and dietitians. A total of 335 female school nutrition teachers and dietitians from Incheon area were surveyed by a self-report questionnaire in November 2010. Collected data were processed using SPSS 15.0. The reliability of the questionnaire was tested and differences between the two groups were analyzed using the Student's t-test, the chi-square test, and a two-way analysis of variance (ANOVA). The job satisfaction level of nutrition teachers was higher than that of dietitians. The effect of role conflict and job satisfaction for nutrition teachers and dietitians was different according to age. In addition, self-efficacy, job satisfaction, and job involvement of nutrition teachers and dietitians were influenced by their annual salaries. The frequency of meals served also affected role conflict, job satisfaction, and job involvement of the nutrition teachers and dietitians, and the effect of job involvement by the nutrition teachers and dietitians was different according to meal service type. Therefore, it is necessary to establish strategies for resolving role conflicts among school foodservice specialists and improve their self-efficacy for enhancing consumer's satisfaction with the general quality of school food service. These efforts may contribute to job satisfaction and job involvement of food service specialists and ultimately to the productivity of food service and the establishment of food service specialist roles.

Objectives: We conducted a qualitative study to explore the feasibility of mobile applications for self-monitoring of diet. Methods: We conducted in-depth and focus group interviews with eight laymen who had used mobile dietary applications and eight experts. Interviews were audio-recorded and analyzed using an open coding method. Results: The qualitative data of our study revealed two key themes: (1) perceptions, opinions and attitudes towards mobile applications of self-monitoring of diet and (2) future directions to improve mobile applications. Conclusions: Our qualitative study suggested the potential use of mobile applications as a food-tracking and dietary monitoring tool and the need for improved mobile applications for self-monitoring of diet. The results of our study may provide insights into how to technically improve mobile applications for self-monitoring of diet, how to utilize dietary data generated through mobile applications, and how to improve individual's health though mobile applications.

The Dietary Reference Intakes which were developed by the Food and Nutrition Board, National Academy of Sciences of the United States, and Health Canada provide a good deal of information on nutritional requirements which apply to Korea. In addition, the processes of evidence based review of information on nutrient needs, dietary excess, and the assessment and planning of dietary intakes may be useful in Korea as well as North America. However, other aspects of the Dietary Reference Intakes may not be appropriate. This article discusses these issues.

The objective of the study was to define dietary patterns in the representative Korean adult population and to explore their associations with other factors. The Korean National Health and Nutrition Survey was conducted on a stratified random sample (n = 9,968) of the Korean population in 2001. This study analyzed data of 5,721 adult population aged 30 and over. Demographic and lifestyle factors were assessed by questionnaires and food consumption by a 24-h recall method. Cluster analysis identified two dietary patterns with 22 food groups: the larger group that included $85\%$ of total subjects was named as the 'traditional' pattern due to greater intakes of white rice, kimchi, and vegetables, and the smaller group was named as the 'modified' pattern which had greater intakes of noodles, bread, snack, and fast foods. The modified pattern had significantly higher proportion in younger age, higher educational level, residing in metropolitan area, and higher household income. The modified group showed significantly higher intake of all nutrients except carbohydrate. Percent of energy from fat intake, $22\%$ was significantly higher in the modified group than $14\%$ in the traditional group. There were no differences in prevalence of metabolic syndrome and its 5 components among patterns. In conclusion, there were two distinctive patterns that were associated with socio-demographic, nutrient intake, and health risk factors in Korea. It should be considered when designing nutrition policy and intervention program.

Vitamin D, a free sunshine vitamin available for mankind from nature, is capable to avert many health-related critical circumstances. Vitamin D is no more regarded as a nutrient involved in bone metabolism alone. The presence of vitamin D receptor in a number of tissues implies that vitamin D has various physiological roles apart from calcium and phosphorus metabolism. Low serum vitamin D has been found to be associated with various types of metabolic illness such as obesity, diabetes mellitus, insulin resistance, cardiovascular diseases including hypertension. Various studies reported that vitamin D insufficiency or deficiency in linked with metabolic syndrome risk. This review focuses on various metabolic diseases and its relationship with serum vitamin D status.

The purpose of this study was to investigate self-perception of health and body image, blood lipid profiles and nutrient intake of adolescents. The subjects were 686 adolescent boys (379 middle school students, 307 high school students) and 613 adolescent girls (272 middle school students, 341 high school students) in Incheon. This cross-sectional survey was conducted by a self-administered questionnaire. Fasting blood samples were obtained and analyzed for triglyceride, total cholesterol and LDL- and HDL-cholesterol. Nutrient intakes collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program. Statistical analysis was conducted using SPSS 10.0 program. Average age, height and weight of male middle school students were 13.8 years, 163.5cm, 56.0kg and those of male high school students were 16.5 years, 171.7cm, 64.3kg. In female, average age, height and weight of middle school students were 13.7 years, 157.1cm, 51.5kg and those of high school students were 16.6 years, 159.7cm, 56.8kg. Female middle school students perceived their health status significantly better compared to female high school students (p < 0.001). Female high school students perceived themselves significantly fatter compared to female middle school students (p < 0.05). Average TG level of female middle school students was significantly higher compared to female high school students (p < 0.01). Nutrient intakes of the male and female students except phosphorus were lower than the Korean RDA. Especially, calcium and iron intakes of male and female students were under the 65% of the Korean RDA. Therefore, proper nutrition education is required for Korean adolescents to encourage desirable food habits and maintain nutritional lipids status. (J Community Nutrition 5(1) : 3∼12, 2003)
