Improved nutritional intake contributes to maintaining health and quality of life in elderly population and also reducing individual and social medical costs. Most of nutrition assistance programs for elderly, such as congregate or home-delivered meal programs, are not currently serviced in rural communities mainly due to low cost efficiency of program operation. However, the needs and necessity of such programs are presumed to be higher in rural area where the population density of elderly at nutritional risk is relatively high. Therefore, the purpose of this study was to develop a community-based meal program for the rural elderly. In 2007, four rural communities located in Jeon-Nam province were selected and the pilot meal program was applied for three months. Following are key features of the meal program model developed in this study: 1) meal production and service are operated by elderly participants to overcome the voluntary personnel shortage 2) utilization of locally-produced foods is maximized to reduce the meal cost, 3) traditional cooking methods are applied to adjust the food preference of elderly, and 4) foods are serviced on site to minimize the food safety problem possibly caused by delivery process. The pilot programs resulted in high satisfaction with the programs of participating elderly. The community-based meal program model developed in this study is expected to be used as an effective nutrition and health intervention model for the rural elderly.

This study was conducted to assess the nutritional status of female students in the 6th grade in a rural primary school. The anthropometric data showed their mean height and weight were 149.5$\pm$6.5cm and 41.3$\pm$7.6kg, respectively, which are slightly higher than those in the Korean Standard Growth data. It was further observed that there was a wide variation in terms of physical growth and development among subjects. The mean hematocrit value was 40.3$\pm$3.3$\%$ and the mean hemoglobin concentration was 12.9$\pm$1.0gm/㎗. It was proven that 22.8$\%$ of subjects were anemic based on the WHO standards for hemoglobin level. Twenty four hour dietary recall revealed that their food intakes of subjects was appropriate, compared to the RDA except for Ca. Mean Ca intake among subjects was 381.3mg which is 47.7$\%$ of RDA. Nutrition education from mothers and the school influence nutrient intake significantly. Special nutrition education programs targeting mothers and students should be developed to provide practical assistance such as food choice and the forming of good eating habit.

The purpose of this study was to investigate the effect of $7-MEGA^{TM}$ 500 on the improvement of skin aging in an UVB-induced photo-aging model of hairless mice. The dorsal skin of hairless mice was exposed to UVB three times a week for 12 weeks to induce skin wrinkle. After inducing the wrinkle, $7-MEGA^{TM}$ 500 was orally administered once a day for 4 weeks. Skin thickness, skin barrier function, and wrinkle indicators were improved by treatment with $7-MEGA^{TM}$ 500. Both gene and protein expression levels of MMP-3 and c-Jun in skin were significantly decreased by $7-MEGA^{TM}$ 500. Therefore, the intake of $7-MEGA^{TM}$ 500 is thought to have a positive effect on the improvement of skin aging, although further studies are needed.

The purpose of this study was to examine the levels of satisfaction, and awareness, as well as evaluations of internship programs between major and non-major students in food and nutrition. The survey was conducted via questionnaire to 80 major and 113 non-major students in food and nutrition who had finished an internship. For the primary internship facilities, the proportions were 51.3% in foodservice for the major group and 57.4% in business & industry for the non-major group. For the internship period, the proportions were 71.2% for under 2 weeks in the major group, and 42.9% for $2{\sim}4$ weeks in the non-major group(p<0.001). The proportions of students who were provided orientation from a professor(p<0.001), and visiting guidance by a professor(p<0.001), were 40.5% and 35.4%, respectively, in the major group and 73.4% and 82.1 %, respectively, in the non-major group. The proportions answering that the internship was a necessity were 95.0% in the major group and 75.2% in the non-major group(p<0.001). The major group had significantly higher satisfaction scores for location of the internship facility, internship period, and connection between education and practice as compared to the non-major group. However, the satisfaction score for professor's guidance during the internship was significantly lower in the major group than the other group. The evaluation score for 'I did my best when doing my work' was significantly higher in the major group than the non-major group. The major group had significantly higher awareness scores for the internship's degree of assistance in improving skills, making use of knowledge, and adapting to the field, as compared to non-major group. In conclusion, students majoring in food and nutrition faithfully participated in their internship programs, with higher degrees of satisfaction and awareness, and higher evaluations. However, more effective internship program with intensified and developed guidance by professor are needed.

In 1962 the governing bodies of FAO and WHO approved the establishment of a joint FAO/WHO Food Standards Programme, the creation of a jointly sponsored body to be known as the Codex Alimentarius commission to implement the Programme. It can reasonably be claimed that the Commission has assumad the leading role in establishing internation food standards throughout the world. The Codex Committee of Food Hygiene has received much advice and assistance from other international organization which have been working in this field for a number of years. In particular, it has received valuable background documentation from the International Commission on Microbiological Specifications for Foods(ICMSF) which was set up by the International Association of Microbiological Societies(IAMS), and also from the International Organization for Standardization (ISO). Nevertheless, in spite of the information supplied by governments and research bodies in this field, microbiological standards have proved to be a highly controversial subject from the point of view of Codex standards. When it is decided to establish a microbiological standard for a food or class of foods, the following technical and administrative aspects must be considered: 1) The standard should be based on factual studies and serve one or more of the following objectives: (1) to determine the conditions of hygiene under which the food should be manufactured; (2) to minimize the hazards to public health; (3) to measure the keeping quality and storage potential of the food 2) The standard should be attainable under practicable operating and commercial conditions and should not entail the use of excessive heat treatment or the additions of extra preservatives. 3) The standard should be determined after investigation of the processing operation. 4) The standard should be as simple and inexpensive to administer as possible, the number of tests being kept to a minimum. 5) Details of methods to be used for sampling, examining and reporting should accompany all published microbiological standards. 6) In establishing tolerance levels for the permissible number of defective samples, allowance should be made for sampling and other variations due to differences in the laboratory methods. The following additional points should be kept in mind: 1) It is not satisfactory to establish one set of microbiological standards for a miscellaneous group of foods, such as“frozen foods”or“precooked foods”. 2) Microbiological standards should be applied first to the more hazardous types of food on the basis of experience of expected microbiological levels, taking into account variations in composition, processing procedures, and storage. 3) When a standard is established, there should be a definite relationship between the standard and the hazard against which it is meant to protect the public. 4) The sensitivity, reliability, and reproducibility of the sampling and analytical methods should be compared in different laboratories and the methods to be used should be specified in detail as part of the standard. 5) Tolerances should be included in the standard to account for inaccuracies of sampling and analysis. 6) Standards should be applied on a voluntary basis before compliance is made mandatory.
