We can make Samul Chol Pyon to add four powdered Korean medicines to Chol Pyon. The purpose of this study is to present the standard recipe of Samul Chol-Pyon for the taste of the moderns, taking the tests of physical charcateristics, sensory qualities. The white Chol Pyon and the group of 5% raw materials for Samul tang are comparatively good for color, odor, taste, softness, chewiness and overall quallity with other group of raw materials. To add Korean medicine browns the Samul Chol Pyon much deeper. The changes in textural properties of Chol pyon during storage at 20$\pm$5oC were measured using a rheometer for hardness, fractureability, adhesiveness, resilience, and cohesiveness. The hardness, fractureability and adhesiveness were increased with the additon of in Samul tang raw material powder. The cohesiveness and chewiness were increased by adding Samul tang powder in the course of time. The Chol Pyon prepared with 5% of Samul tang powder showed the superior sensory qualities as Samul Chol Pyon.

The purpose of this research was to observe the management system of 18 free meal service centers for the low-income homebound elderly in Chungcheongbuk-Do In order researchers interviewed staff members of the free meal service centers. Based on the results of interviews with staff members of the meal service organization. only two centers used a standard recipe. and most of the meal preparation was controlled under the experience of volunteers. Only two meal service centers employed dietitians due to the lak of budgets. The cost of a meal per day ranged from ￦ 556 to ￦2,750 and the number of attendants at meal service ranged from 35 to 350 persons. The budget for most of the meal service centers is not enough to provide meals for the elderly who want to participated in free meal service programs. Home delivery meal service was not considered due to the lake of manpower and areal dispersion in rural ares. Most meal service organizations did not cooperate with other community service organizations. Several improvement strategies are recommended for the effective running of the free meal service centers. First, a nutrition specialist should be included in the staff members of the service organization to provide nutritious meal service to the elderly Second, a joint control system might be introduced into the present system to reduced the cost and the recover the limitations of areal dispersion. Third, service, coordination should be considered to overcome the problem of lake resources.

The use of food frequency questionnaire to estimate dietary intake has become widespread in epidemiologic studies. It has been suggested that knowledge about a person's usual serving size of each food, in addition to consumption frequency, will improve the accuracy of this method. This study was performed to investigate the nutritional status and one sowing sizes of commonly consumed dishes in Korean college women. Intakes of dish or food in 156 college women were measured by 7-day weighed food records in May, 1992 and May, 1993. For each dish or food, variance in one serving size was partitioned into within-person(intraindividual) and between-person(interindividual) components. All nutrient intakes except vitamin A and vitamin C were less adequate. The major dish groups which contributed to the most daily nutrient intakes were boiled rice, bread, fruits, dairy product, and biscuit and snack groups. In more than 50% of dishes, the within-person variation was greater than between-person variation. And the variety and amount of food which was used in one dish were too variable to make standard recipe.

The main purposes of this study were to survey and assess the current situation surrounding solid waste generation in school foodservices, to identify and evaluate the measures(reduction and recycling programs) taken by the foodservices for waste disposal, and to suggest appropriate reform measures to improve the current status, especially in terms of environmental preservation. Questionnaires on solid waste management practices were mailed to 206 school foodservice dietitians in the Kyungbuk region : a 64.0%(N = 130) response rate was obtained. While there are food waste and packaging waste generated from the foodservice operations, about a third(34.1%) of the foodservice operations were responsible for the disposal of both the food wastes and packaging wastes. About 90% of school foodservice managers were responsible for managing solid wastes. The primary recycling methods of leftovers generated from the school food service operations were livestock feed(76.0%). About 60.0% of school foodservice managers conducted the food waste reduction program. The performance by the foodservice managers in reducing the food waste was not satisfactory in several fields, such as developing environmentally friendly menus or abiding by the standard recipe, etc. In addition, the government assistance system was not properly working in the food service management. In conclusion, we should focus on increasing the performance in reducing the food waste by the foodservice managers, strengthening and facilitating the government assistance system for the food waste management and to develop education methods and education materials for food waste management.

The purpose of this study was to develop the website-based program for individual meal planning. The program consisted of the basic information of clients, dietary habits, analysis of nutrient intakes and menu planning. The first part of the program consisted of general information such as general characteristics and anthropometric data of clients. The second part was designed to investigate the dietary habits, food intake frequency, nutrition knowledge, and drinking and smoking habits of the clients. The third part consisted of analysis of nutrient intakes including three major nutrients, calorie intake by foods and alcohol, and ratio of individual fatty acid intake. Nutrient intakes was evaluated by comparing with dietary reference intakes. In the final part, the program included the menu planning by using standard recipe. This system was also designed to insert, remove or change the food items or amount according to the user need. It is expected that the development of a meal planning system based on the internet can facilitate the professional dietary counseling, and thus help to improve the health of people.

Optical emission spectroscopy (OES) is often used for real-time analysis of the plasma processes. OES has been suggested as a primary plasma process monitoring tool. It has the advantage of non-invasive in-situ monitoring capability but selecting the proper wavelengths for the analysis of OES data generally relies on empirically established methods. In this paper, we propose a practical method for the selection of OES wavelength peaks for the analysis of plasma etch process and this is done by investigating reactants and by-product gas species that reside in the plasma etch chamber. Wavelength selection criteria are based on the standard deviation and correlation coefficients. Moreover, chemical actinometry is employed for the normalization of the selected wavelengths. We also present the importance of chemical actinometry of OES data for quantitative analysis of plasma. Then, the suggested OES peak selection method is employed.. This method is used to find out the reason behind abnormal etching of PR erosion during a series of $SiO_2$ etch processes using the same recipe. From the experimental verification, we convinced that OES is not only capable for real-time detection of abnormal plasma process but it is also useful for the analysis of suspicious plasma behavior.
