The purpose of this study is to evaluate the technological competitiveness of the environmental industry with developed countries in order to establish an international market expansion strategy of the Korean environmental industry and technology. In order to evaluate the competitiveness of the environmental industry and technology, core technologies were classified by the environmental industry sectors based on the classification system of the domestic and international environmental industry and technology. After developing the evaluation index data, the Delphi analysis, journal and patent analysis, as well as the export and import analysis were carried out and the standardization analysis was performed on the index data. Moreover, the weights of each evaluation index were calculated using the AHP(Analytic Hierarchy Process) method and the evaluation results of competitiveness of the environmental industry and technology in Korea, the United States, the United Kingdom, Germany, and France were derived. As a result of the evaluation, the United States was rated with the highest technological competitiveness in all the environmental industry sectors, while Korea got the lowest technological competitiveness rating compared to the 4 developed countries. In particular, Korea got the lowest level of technological competitiveness in the sector of multi-media environmental management and development for a sustainable social system. Therefore, in order for the Korean environmental industry and technology to enter the global advanced market, it is necessary to strengthen the competitiveness through the development of the fourth environmental industry based on IoT(Internet of Things), cloud, big data, mobile, and AI(Artificial Intelligence), which are currently the country's domestic strengths.

As the population is getting older, medical expenses amount of the whole is keep increasing. So, the pressure of the finances, Health Insurance, Medical Care Assistance Act and etc, is getting higher. The share of healthcare-expense is increasing due to elderly illness. And it became a social problem; we analysed present state of senior healthcare in South Korea-looked into current laws and policies, and found problems. We tried to suggest improvements that drew from the current state of foreign country senior healthcare of those problems. For the result, we found the problem in relevant-law system of senior healthcare guarantee. In this study, we proposed the ways to qualitatively upgrade of medical standard that considered on elderly' features: the strengthened guarantee for healthcare, financial secure for long-term convalescence benefit, linking and functional reinforcement for elderly welfare and long-term convalescence insurance, the solution for overlapped laws about convalescence in long-term convalescence insurance and elderly welfare, a betterment of grading, and a home service consolidation. We need to secure right amount of emergency medical service budget, and effective management system for the improved level of senior severely emergency medical service. Furthermore, we suggested that South Korea needs to legislate [The Law for Senior Medical Secure] to respond to rapidly increasing senior healthcare fee.

Our country has made every efforts to develop Real Estate Transaction culture with emphasis on Licensed Realtors by introducing Real Estate Transaction Law in 1983. Also, MOLIT(Ministry of Land, Infrastructure and Transport) designated several organizations including KAR(Korea Association of Realtors) as Real Estate Transaction Information Network Licensees for data credibility enhancement and transaction transparency. Nevertheless, the level of law abiding spirit and transaction culture are still similar to those of the old 'Bokdeokbang' era. The under-developed transaction behaviors prevent the social capital of people's credibility on Licensed Realtors from advancing, and results in the outcomes of unnecessary social cost. That is, very low credibility on the data on Sales Items in the market and the fear of speculative real estate price uprise and market distortions are continuing on. In this context, the purpose of this study is to propose the model of GIS-based Modernized Real Estate Transaction System and its execution policies to support credible Real Estate Information to the general public for efficient transactions in the market. Accordingly, the study aims at contributing to the modernization of Real Estate Transactions, fostering competitiveness of Realtors in the Real Estate Market.

Travellers consider extra travel time to be arriving their destination because of uncertainty of travel. So it is important to make predictable highway by providing information of travel time variability to traveller so as to enhance level of service at highway. In order to make predictable highway, it is necessary to develope measures of travel time variability that travellers can easily understand. Recently advanced country including the United States, travel time variability index are actively studied. In earlier study, 95percentile of travel time is considered to be most important calculation index of travel time variability. In this study, is has focused on the propriety analysis of 95percentile of travel time in domestic transportation environment. Result of analysis, All of measures(80percentile of travel time, 90percentile of travel time, 95percentile of travel time) show the tendency to increase when case of weather factor occur compare to normal condition under LOS A~D. Especially 95percentile of travel time increased sensitively.

Agricultural extension service in Ethiopia was started in early 1950s with mandate of transferring local research outputs and technologies to farmers, and importing technologies and improved practices from abroad. Extension service provided in this early time was limited to areas surrounding the experiment stations. Since then, Ethiopian Agricultural extension service has passed through at least five stages: the land grant extension system, the Comprehensive Package Programs, the Minimum Package Projects, the Peasant Agricultural Development Program, and the Participatory Demonstration and Training Extension System (PADETS). The comprehensive package extension program was initially implemented in selected pilot areas and eventually to be scaled up to cover about 90% of the farming community within 15-20 years time. The program used demonstration plots managed by development agents and used to train farmers organized through various field days. However, since all of these programs were operational in only small areas, the vast majority of the country was out of their reach. Through Participatory Demonstration and Training Extension System, the extension service in Ethiopia has come under the spotlight and government debates and external reviews are putting additional scrutiny on the system. Despite this long history, the system is still in its infancy in terms of coverage, communication and institutional pluralism. Currently in Ethiopia the Agricultural extension is provided primarily by the public sector, operating in a decentralized manner through which extension is implemented at the district level. Therefore, the main focus of this paper is to scrutinize the past, the present and the future Agricultural extension system in Ethiopia.

The maternal and child health is a basis of national health, and indicates the level of social welfare and health of the country, because it is related with community welfare status, general cultural conditions, and medical and health sciences. This is a study carried out to identify the present practices of maternal and child health care programs implemented by the private clinics located in Guns(counties ; rural area) in Kyungsangnam Province and to propose alternatives to improve their current programs through a self-administrative questionnaire. The subjects were 90 private physicians who operated their own clinics since 1990 and were general practitioners, Obstertrician/Gynecologists or pediatricians: This survey was conducted by mail from 15 January to 25 February 1992. The response rate was 94.4 percent. 1) The major manpower for MCH programs of the studied clinics was physicians and nurseaids. 70.3% of physicians were general practitioners, 81.1% of nursing manpower were nurseaids. 31.1% of the studied clinics employed lab-technicians. 89.2% of them had MCH room whatever the size and the setting, and 84.4% of Ob/Gyn clinics installed laboratory equipments. 2) 55.4% and 63.5% of the studied clinics provided 151 or above consulting services and curative services of MCH per physician a month respectively and 33.8% and 25.7% of them provided 10 or less consulting services and curative services per physician a month. 91.9% of lab-technicians had 10 or less laboratory tests per technician a month. 3) There was a difference between Ob/Gyn and pediatric clinics in terms of services delivered : for example, 80% of Ob/Gyn clinics provided pre- and post- natal care services, while 84.6% of pediatric clinics provided vaccinations for children. It was also found that only a few of general practitioners involved pre-and post- natal care services. 4) There were no clinics which had opened regular health education session but 24.3% of them had opened the sessions irregularly. Ob/Gyn clinics put emphasis on maternity and pediatric clinics did on child health, but general practitioners touched with both maternal and child health. 21.6% of the studied clinics had some kind of educational materials for MCH programs. Most of the materials were pamphlets or small booklets. 5) Proteinuria/glucosuria, blood pressure and blood type were tested in 48.6~69% of the studied clinics ; tests for blood sugar and hepatitis B were provided in 39.2~41.9% of them, most of them were done in Ob/Gyn clinics. 6) 41.9% of physicians, 29.7% of nurses and 45.9% of nurses-aids wanted to receive on-job-training for MCH programs.

As the supply of aggregate needed in the construction site becomes difficult due to preservation of environment and exhaust of aggregate resource, a research for replacement aggregate in shortage is being actively progressed and a copper slag is also a kind of replacing aggregate. To use copper slag as fine aggregate of concrete, many studies are already conducted in each of the advanced countries and in the state of applying these at the site. In the year of 2000 a Korea industrial standard of Copper slag aggregate for concrete was established in our country so that this can be applied in the construction site. This study is to find out whether copper slag is equipped with the physical and chemical requirements for the use in concrete aggregate, and to analyze the dynamic properties of copper slag concrete that replaces 25, 50, 75, 100% of fine aggregate. Copper slag study not only satisfies the using condition of fine aggregate, but also reveals high level of physical property compared to ordinary concrete up to 50% of sand replacement rate. In the future after confirming the durability of concrete using copper slag, it is judged to be advantageous for the preservation of environment to use this as a replacement material for natural aggregate.

This study figured out the influential factors of region-based characteristic factors in our country upon asthmatic occurrence. Research subjects were 2,266,451 people who were confirmed the diagnosis of asthma (J45~J46) among patients in national health insurance for the year in 2010. The influence in each of factors upon the asthmatic occurrence was analyzed through hierarchical regression after comparing difference in asthmatic occurrence by basic local government. As a result of hierarchical regression, the whole asthmatic occurrence had significant difference in infants ratio, $SO_2$,Temperature, basin and dam area. The asthmatic occurrence had significant difference in subjective awareness of health level, $SO_2$, basin and dam area. A case of asthmatic occurrence had significant difference in infants ratio, temperature, $NO_2$ and coastal area. Diverse characteristic factors by region were indicated to have influence upon the asthmatic occurrence by causing or weakening asthma through mutually complex action. Accordingly, a region-based customized environmental health measure will need to be arranged that infants and elderly people, who are vulnerable classes, can be protected and prevented from harmful environment of asthma.

This study conducted researches to get related basic materials and grope for a way to prevent or treat suicidal ideation. For the researches, the study examined eco-systematical variables of suicidal ideation of those who are 65 years or older, and the influence of the change in the eco-systematical variables by using the source materials researched in sixteen cities/provinces over the country from KOWEPS(Korea Welfare Panel Study), and then reviewed if there any difference according to whether they had suicidal ideation or thought in the previous year. The analysis result shows that each variable of the ecological system such as individual, family, and social system has an effect on the elderly's suicidal ideation, and there is difference in the influence factor according to whether they had suicidal ideation in the previous year or not. The result implies the policy to cope with the elderly's suicide needs multidimensional approach of individual, family, and society rather than a simple individual level. And also there should be a different support or service according to their situation or conditions like previous suicidal ideation. Especially, it is quite significant that the factors do not influence the elderly who had suicidal ideation in the previous year, but have an effect on those who did not have any suicidal ideation, which means that the proactive and preventive support related to suicidal ideation would guarantee a more efficient and effective policy.
