This study was designed to analyze the status of government policy on the computerization of health centers throughout the country and to identify the factors affecting a successful implementation of the information system. As expected, age and commitment of health center director, computer budgets, user training, and technical supports from the information specialists were the important factors influencing the successful implementation of the system. Compared with the urban health centers, fewer rural health centers installed the system perhaps due to lack budgets and the urban-oriented system features. Moreover, the systems were unevenly distributed according to the geographic regions. Some strategies for successful dissemination of the systems were also suggested.

Recently, the improvement of computer capacities and artificial intelligence ware caused to employ for prediction of residual stresses and strength evaluation. There are a lot of researches regarding the measurement and prediction of residual stresses for weldment using a neural network in the advanced countries, but in our country, a neural network as a technical part, has only been used on the possibilities of employment for welding area. Furthermore, the relationship between residual stress and process parameters using a neural network was wholly lacking. Therefore development of a new technical method for the optimized process parameters on the reduction of residual stress and applyment of real-time production line should be developed. The objectives of this paper is to measure the residual stress of butt welded specimen using strain gage sectioning method and to apply them to a neural network for prediction of residual stresses on a given process parameter. Also, the assessment of the developed system using a neural network was carried out

This paper sought to provide information regarding the water resources in the Philippines, focusing on the issues of water quality, status of water use and water scarcity, and other threats to water availability. Although the country has sufficient amount of water resources, it was found out that water availability is still threatened by some major water resources problems: increasing water demand due to drastic growth in population, water resources pollution, droughts and flooding and weak institutional framework to address these problems. Water quality problems include increasing groundwater and surface water pollution. Moreover, drought and flooding have also increased damages in recent years due to deteriorating watersheds and high economic and population growth. In relation to these, the government enacted national laws to define and deal with water control and quality management. The objective of this research was to present and evaluate current conditions and issues on Philippine water resources.

The contraception practice rate in Korea has steadily increased from 9% in 1964 to 72% in 1987. Accordingly, natural increase rate of population declined from 28.4 per 1,000 in 1964 to 12.4 per 1,000 in 1987. Notably in recent years, the acceptance of surgical contraception services has sharply increased in this country. Now the author analyzes various factors influencing successful vasectomy and vasovasostomy based on his experience in performing more than 8,000 vasectomies and 1,000 vasovasostomies during the past 25 years. These various factors consist of preoperative screening interview, surgical vasectomy technique, vas irrigation technique, open-ended vasectomy, complications from vasectomy, sperm granuloma formation, spermatogenesis and steroidogenesis after vasectomy, immunological consequences after vasectomy, prostatic diseases and vasectomy, late post-vasectomy syndrome, psychological effects after vasectomy, and success rates of vasovasostomy. Besides, the author makes more comments on the results of the clinical trials on new approaches to reversible vas occlusion technique with a new device of Intravasal Thread and to reversible suppression of spermatogenesis with long-acting sex hormones.

Geotextile container method is an environment-friendly construction method that is utilized to build up a breakwater and an underwater embankment, etc. using geotextile container, which is producted by filling the geotextile bag with sand or dredged materials. Geotextile containers are divided into geobags, geotubes and geocontainers based on their size and production method. In recent years, the number of application for the geotextile container method is rapidly increasing in the world, and the development of the effective construction method is focused. In this study, the application and the achievement of the geotextile container method will be introduced, and the practical construction examples and the trend of technology development in foreign country will be discussed.

철근콘크리트구조의 연성에 영향을 미치는 중요한 요소인 철근의 최소연신율 규정은 각 나라 규격마다 상이하다. 이는 각 규격마다 철근의 연신율을 산출하는 기준인 표점거리가 다르기 때문이다. 이에 본 연구에서는 각기 다른 표점거리를 가지고 있는 국내외 규격을 비교하고, 단조증가 인장시험을 통하여 어떠한 규격의 연신율 규정이 더 엄격한지에 대해 실험적으로 분석 평가하였다.

The vibration environment essentially companied by vehicle operation on the road is determined by the shape of road surface, which is called profile. In general, the profile and severity of unpaved road is an important issue in the reliability of durability test for vehicles. In order to maintain severity of unpaved road, it is necessary to develop profilometer system. We developed profilometer system which is composed of data processing computer, power unit, air compressor and sensors. This paper focuses on the severity management of unpaved test courses using neural networks. This paper presents the maintenance range for cross-country course in CPG(Chang-won Proving Ground) and the evaluation of similarity degree between unpaved roads.

In this paper strategic planning is applied for effective management to improve hospital income. Though community hospital has been set up for improving the health status of community, it must be trying to increase income for continuing with referral hospital in the community. The most useful tool of management to do this purpose is thought of strategic planning. Therefore this paper developed strategic planning a typical community hospital, which for it presenting the strategic planning process and developing the simulation model for evaluation of strategic alternatives. In the result it is represented that admission rate is the most sensitive to hospital operating income among the important variables in the model. And simulation by changing the parameter could estimate the yearly hospital income in the response of alternatives. This strategic planning simulation model has had constraints as number of date but also significance such as evaluating the alternatives by quantitative model and at first applying the hospital in our country.

The purpose of this study was to examine the differences of self-confidence and satisfaction level in teaching home economics between home economics majored teachers(HET) and other subject majored teachers(OST). The subjects of this study were 192 home economics teachers randomly selected from 96 middle schools all over the country. The data was collected from 16, september to 12, October, 1996, and was analyzed with descriptive statistics, crosstables, and t-test using SAS program. The major finding were as follows: 1) In general, home econimics is taught mostly by OST in boy' middle school. 92% of OST is employed in boy' middle school and 89.13% of them is employed in private boy' middle school. 2) OST had less in-service experiences than HET on sixth revised curriculum, and had lower recognition than HET on the goal, content, teaching method, evaluation of home economics. 3) There were significant difference on the level of self-confidence and satisfaction in teaching home economics between HET and OST.

Background: The Global Adult Tobacco Survey (GATS) was carried out for systematically monitoring tobacco use and for tracking key tobacco control indicators. Materials and Methods: A total of 70,802 households, including 42,647 in rural areas and 28,155 in urban areas, were covered with a three stage sampling design. Data were collected on sociodemographic characteristics, knowledge, attitude and practices of tobacco consumption.Results: GATS-India highlighted that total tobacco use among its residents is overall 34.6%, varying for males (47.9%) and females (20.7%). The rural areas of the country exhibit comparatively higher prevalence rates (38.4%) in comparison to urban areas (25.3%). Overall, Khaini, a smokeless tobacco product (12.0%), is the most popular form of tobacco use among males and females, followed by bidi smoking (9.0%). Conclusion: Results of GATS data can be used as baseline for evaluation of new tobacco control approaches in India integrating culturally acceptable and cost effective measures.
