A computer expert system for guiding Japanese style meal menu has been developed by using EXSYS Professional which is one of expert system developing software tools. The expert system nunderstands the situations of clients, and can guide the menu as human experts do by its software program with expert knowledge about the meal menu. In developing the expert system, the elements the clients consider when selecting menu were arranged as questions of the expert system, and the final outcome of the expert system resulted in selecting the final menu appropriate for the client demand, weather, health, etc. In hotel, the expert system can be shared by whole restaurants, and be directly a computer guider to the clients to tell the best choice of the menu. Besides, it can be used for various kinds of bangquets and events. Expert system has been developed and studied by business managers, manufactures, medical fields, and military field. But the studies for applying the expert system in the fields of foods have been scare. Through this study, therefore, the expert system is going to be applied more widely in many fields fo food events.

Recently, near-infrared (NIR) spectroscopy and Raman spectroscopy have received keen interest as powerful techniques for nondestructive analysis of biological materials. The purpose of this review paper is to compare the advantages of NIR and Raman spectroscopy in the nondestructive analysis. Both methods are quite unique and often complementary. For example. NIR spectroscopy is very useful in monitoring in situ the content of components inside biological materials while Raman spectroscopy is very suitable for identifying micro-components on the surface of biological materials. In this article specific characters of the two spectroscopic methods are discussed first and then several examples of applications of NIR and Raman spectroscopy to the biological nondestructive analysis are introduced.

The mycolic acids and fatty acids of mycolic acid- containing bacteria in various types of fluids were analyzed using capillary gas chromatography and mass spectrometry. As model strains, Brevibacterium and Coryebacterium species, which have corynomycolic acids ill the range of $C_{32}C_{36}$ in the whole cell, were investigated. Optimized solvents extraction procedures for the mycolic acids and fatty acids from the culture fluids were: chloroform/methanol (1:2, v/v) as the first extraction solvents fur 4 h; and chlorofunuwater (1:1, v/v) as the second extraction solvents far 1 h. These conditions gave above 95% recovery yields fur mycolic acids from the culture fluids. The mycolic acid profile for the whole cells and the culture fluids were similar fur all the media tested. Thus, the procedure described here could be applied for the identification of mycolic acid-containing bacteria in fermentation broth or liquid from of foods.

Chitosan has been widely applied to the products in various industries such as textile fabrics, apparels, foods, medical area, etc. Cochineal has long been employed as one of natural dyestuffs in the textile industry. The effect of chitosan pre-treatment on the low-stress physical and mechanical properties of cochineal-dyed fabrics including cotton, silk, nylon and polyester fabrics was investigated in this study. The chitosan treatment and mordanting of the fabrics changed the bending, shear, compression, and surface properties of the fabrics. In cotton fabric specimens, while the increase of B(bending rigidity) of cotton is relatively high, the increase of G(shear rigidity) of cotton is relatively low. In nylon and PET fabric specimens, while the increase tendency of B is relatively low, that of G is high compared to the corresponding cotton fabrics.

In order to produce lactic acid and calcium lactate very useful for foods and medical supplies, lactic acid fermentation was studied by Lactobacillus sporogenes, a spore forming lactic acid bacterium. When this bacterium was cultured aerobically in the spore forming medium, the spore forming rate was 96.0% as total cell number 20$\times$108/ml, spore number 19.2$\times$108/ml. One minute agitating every 1 hour in the flask culture, or agitation of 100rpm in the fermenter was most efficient to continue to ferment at 45$^{\circ}C$ for 4days in the fermentation medium containing 10% glucose as carbohydrate and CaCO3 as a neutralizing agent. This homofermentative lactic acid bacterium showed fermentation yield of 99.3% and more than 98.2% of the yield was L(+)-lactic acid.

Medical concept of the skin disease is a symptom like itchs. It outbreakes by immunologic and nonimmunologic mechanisms. The most common case is hypersensitive reaction intermediated by IgE. Other case of immunologic mechanism includes activation of the complement system. Autoimmune antibodies for histamine-secreting mast cell IgE receptors are found in some patients suffer from chronic skin paroxysm. Most common causes of acute skin paroxysm are foods, viruses, parasite infections and drugs. Causes of chronic skin paroxysm are undiscovered. Air pollution, simplification of eating habits, habitual eating of convenience food; drug abuse in present days made skin disease more common. Now many methods of acupunctural treatments are being used clinically. So this report presents some views about acupunctural treatments for the Skin disease.

Objectives : The aim of this study was the collection of dietary treatments of atopic dermatitis Methods : We surveyed the western and oriental medical book concernig the atopic dermatitis. Results : The 20~30% of patients with atopic dermatitis have hypersensitivity reaction on the major food antigen. The food restriction to prevent allergy reaction need to take effect early during infancy and childhood. In oriental medicine, a heat-poison(熱毒) caused by food affects a fetus of pregnancy. So the food, the regimen and the harmony of the five tastes is stressed the need. When certain foods are restricted to prevent allergy reaction, infant and children with food related Atopic Dermatitis need extra dietary efforts to maintain optimal nutrition as they are in the growth period.

This study was conducted to provide a vitamin $B_{12}$ database for the representative Korean food items and to assess the dietary intake assessment of vitamin $B_{12}$ for Koreans. The vitamin $B_{12}$ content of 106 foods had been determined by high performance liquid chromatography (HPLC) using column switching method. Rich sources of vitamin $B_{12}$ were meats, milk, and egg ($0.3-3.4\;{\mu}g/100g$). Vegetables and fruits contained vitamin $B_{12}$ below limit of detection (LOD). The major food sources for vitamin $B_{12}$ intake were milk (72.0%), meats (22.3%), egg (3.6%), and fishes & shellfishes (2.1%). Mean vitamin $B_{12}$ intake of Koreans was $3.16\;{\mu}g$/person/day. The proportion of population with intake below estimate average requirement (EAR) and above recommended intake (RI) of vitamin $B_{12}$ was 60.7 and 36.5%, respectively. The vitamin $B_{12}$ intake level of young children with 1-2 years which was 834.6% of RI while the intake level of the older adults 50 years and older was only 70.0% of RI. Also, there were regional differences between urban and rural area. The population with intake below RI was larger than that with intake above RI in Korea.

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.
