We developed the portable blood analysis system, which can be measured pH of the blood. This system is composed to electronic circuit, mechanism, and system software. Electronic circuit is composed to the sensor, pre-amp part, temperature regulation part, fluid sensing part, A/D(analog to digital) conversion part, main and peripheral device processing part. And the mechanism is composed to the flow cell and the liquid flow part. The liquid flow part is consisted of blood and washing control system under the control of the 6-channel solenoid valve and syringe rump. The system software is composed to measurement program, calibration program, washing and diagnostic program. The program of each routine is designed as sequential process for an efficiency. And the portable pH analysis system used two-point calibration method using the two types of corrective liquid. As a result, we obtained the calibration curve and calculated the value of pH. For verifying the system, we confirmed the output voltage of the sensor, and estimated reappearance of system using the standard liquid.

The ageing problem of the population has been emerging in Korea since 1970's so that it is expecting the elderly 65 years and over among the total population from $4.5\%$ in 1988 to be $6.3\%$ in year 2000. This study was conducted to provide secure policy development in coming years for the aged on medical and health care aspects based on the examining current status of the aged problems and health care policies and systems. The study divided into four parts; The first part examined the medical insurance program and public assistance program of the health services in relation to the aged. The second part emphasized on reduction of medical care cost for the aged. The third part studied the regular health check-up program and health education for the aged. The fourth part examined the chronic disease management programs for the aged and strategies of the health care service quality improvement and specialized programs. The following recommendations made as the results of the study. 1. At present, the medical insurance program and public assistance program for the medically indigent is not appropriate to the elderly because it is a part of general medical insurance program so that Health Security Law for the Aged is proposed. 2. Medical cost will be increased due to the high occupancy rate of hospital beds and long stay of the elderly so that it is recommended to develop an early discharge program, home health care program, Health hospice and an althernative programs. 3. At present, a regular health check-ups for the elderly is not included in medical insurance program so that it is recommended to be included in the insurance program and at the same time health education program thoroughly developed for the aged. 4. To make proper medical and nursing services on chronic diseases for the elderly, it is recommended manpower development, specialized clinics or hospitals, nursing homes and an equivalent long term care facilitices should be established on the community based and a research institutions also to be related to supper the care programs.

We studied a cluster family in the northern part of the Carina Nebula (NGC 3372) a group of clusters near NGC 3324 (Tr 15, NGC 3293, Loden 165, Loden 153 and IC 2581). We used data from UCAC4 to determine the cluster's membership and the near infrared CMDs of each cluster. We analyzed the spatial density and elongation as a function of radius for each cluster and found a possible interaction between NGC 3293 and Loden153. However, the shape distortion of NGC 3324 cannot be evaluated because of the inhomogenity in the coverage of UCAC4 in the east part of NGC 3324.

As environmental issues is important thing, our study aims to develop natural adhesives made by rosin instead of synthesis adhesive with the formaldehyde emission. Natural adhesives were formulated to enhance curing speed and adhesion performances with various drying agent contents. Adhesion performances were evaluated with tack values measured by texture analyzer and shear strengths determined by single lap shear test. The adhesion performances of nature adhesives developed in this study and compared with those of overseas natural adhesives made by AURO, BioFa, Livos. Optimum drying agent formulation was Co 0.7 part, Zr 1.0 part, Ca 0.5 part, and Activ8 0.1 part. Shear strength of the adhesives manufactured by the optimum drying agent formulation was $93.2{\pm}19.1N/cm^2$.

This paper describes the development of a general program for the design and part load performance analysis of single-shaft-heavy-duty gas turbines. Efforts are made to fully represent the real component features by the characteristic models and special emphasis is put on the modeling of cooled turbine stages. The design analysis routine is applied to simulate the performance of current gas turbines and its appropriateness for system analysis is validated. Meanwhile, the component parameters of real engines which describe the technology level are obtained. The program is extended to predicting the part load operation of gas turbines with the aid of models for the off-design characteristics of compressor, turbine and other main components. Part load simulation can be carried out only with limited numbers of input data. It is demonstrated that the program accurately estimates the part load characteristics of real turbines.

Traditionally, for space program whose operation environment is severe, high reliability parts, that is class s microcircuit, JANS level semiconductor, and ER passive parts, are reliable choices. But in some case, we must use 'Non-standard Part' which is not verified as high reliability standard part. To use 'Non-standard Part' in space application, the manufacturer should qualify the part and screen potential week part from the flight lot. In this technical memo, I introduce the flight part verification process for KOMPSAT 1 and KOMPSAT 2 program.

It is the purpose at thus survey to get hold at problems in teaching integrated science in middle school. For this purpose, problems and suggestions were collected by questionnaire which were made out by middle school science teachers. Through the analysis of the questionnaire, it was found that the present curriculum of science education in the college of education and the in-service training program were not suitable for training middle school science teacher. Form the results of the analysis, this survey concluded that the curriculum and program mentioned above need improvement as follows. (1) science education curriculum in the college of education should be set up with two part. One is the part that middle school science teachers are trained and the other is the part that high school science teachers are trained. (2) In-service training program should be set off into two kinds. One is the program that middle school science teachers are trained and the other program that high school science teachers are trained.

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.
