Most of the traffic accidents are a rear-end collision and a clash generated in the signalized intersection on the local roads. So, it is demanded that the high-quality of signal control and dilemma zone control. According to the cases generated by foreign countries, we established the strategies which are composed of Volume-Density Control, strategy of the dilemma zone control using R-detector (microwave detector) In Japan and EC-DC Control. MOEs(Measure of effectiveness) are car numbers in the dilemma zone , max-out probability in the safe side and the average stopping delay in the progress side. We choose a signalized intersection in rural highway to analyze the effect of the strategies and practiced an on-the-spot survey. The result of the survey is applied to the basic data in the simulator. Consequently, strategy of the dilemma zone control using R-detector(microwave detector) in Japan is the best effective in the safe side and EC-DC control is the best in the progress side. Based on the result, we developed the effective strategy of the signal control . This strategy is composed of the strategy of Japan and the detector on the stopping line used in the EC-DC control. On the result of the analysis, new strategy is the best effective in two sides.

In an effort to expand working opportunities for women and encourage childbirth, the government of Korea introduced the free infant care policy in 2013. This policy, however, was controversial with regard to issues, such as budget shortages and dissatisfaction based on socioeconomic status. In addition, the lack of evidence-based data regarding adequate age criteria for the entry of children into childcare facilities was noted as a challenge. As child development professionals who are concerned with mental health issues, we investigated the influence and challenges of the free infant care policy with regard to infant mental health. In this review, we examined the policies enacted by developed countries, such as the United Kingdom (UK), and compared them with those in Korea. The childcare systems in Korea and the UK differ historically and socially, but show some similarities, such as maternal responsibility for parenting and household issues. Like Korea, the need for UK childcare facilities increased in the 1990's in response to market recovery and associated increase in female employment. Among the new policies in the UK, the Sure Start program has begun to provide integrated services for infants, particularly to those 0-4 years of age, who are vulnerable to social exclusion. Similar to the Dream Start program in Korea, it has been successful in providing family-related services, resulting in improvements in problematic behaviors of children, enhanced parenting skills, and decreased rates of severely injured children.

Korea's trade balance in service showed surplus in 2012 on the basis of BPM5. This is recorded by 14 years since 1999. This owes to decrease of deficit in tourism balance, increase of surplus in construction and transportation, and shift from deficit to surplus, even in small portion, in personal cultural recreational services balance. While externally the global economic growth becomes inactive and the Korean Won has appreciated, internally Korean service industry is very weak and is not equipped with international competitiveness. This study intends to look into service surplus items and services deficit items and to present measures that will be able to strengthen competitiveness in service industry. As a short case study, German and Japan was benchmarked, as they are the countries which are developed on the basis of manufacturing like Korea. And in this study, by analyzing surplus items and deficit items in trade balance sheet, it is attempted to suggest policies which would be available for strengthening service industry. As the service industry is a highly value-added one, it is necessary to designate promising categories and intensively foster as strategic industry. Service industry has their own characteristics distinguished with manufacturing goods. It has very different logistics and payment system with manufacturing industry. It means there must be independent support systems which reflect the nature of industrial classification in service industry. It is necessary to provide export support system, to organize export market development group, to support marketing, to set common logistics center, to support diplomatic means, to provide legal service and so on.

The National Assembly of R.O.K. has established and developed parliamentary democratic system up to now since the Constitutional Assembly in 1948. However, in order to establish and develop the management system that reflects an inherent character of the parliamentary minutes, lots of things are yet to be improved in institutional and operational aspects. This study aimed to propose the proper management system and improvement methods of the parliamentary minutes by comparing & analyzing minutes management cases of major foreign countries having a long history and the minutes of the National Assembly of R.O.K. First, it is necessary to make in-depth discussions about methods for reorganizing administrative system for the efficient production and management of the parliamentary minutes. Second, for the guarantee of the parliamentary minutes, systematical management based on laws is needed. The various types and value and characteristics involved in the minutes of the National Assembly can be said to start with a congressman, a representative the Nation and a member of the National Assembly. Accordingly, the minutes of the National Assembly produced from parliamentary members who were elected by the people must be freely utilized by the people.

This is the study on the preference of men's jewelry in Korea and China. It started to change and develop the market of modern men's jewelry, which is increasingly growing. The men's jewelry market, in Korea, has developed as small market as part of women's, and since 2006, it has started to grow as men's jewelry. However, it is still treated only by some brands. It is a time when innovation is needed because design diversity is weak. The men's jewelry market in China is rapidly developing under the influence of young emerging rich people. However, as in Korea, a research on the design of men's jewelry is insufficient, so it is urgent to study the preference for men's jewelry. Each survey was conducted on a the tie-pin and cufflinks as the most representative men's jewelry in Korea and China. As a result, both countries were not satisfied with the designs currently being sold. In Korea, the popularity of the tie-pin and the cufflinks is made to some extent, and customizing to consumer and innovative development are required. And, in China, the popularity of the tie-pin and the cufflinks made it possible to expect the growth of the men's jewelry market.

Busan Port, Korea, is a region that must take integrated measures against problems such as the excessive handling of cargo volume, the intensification of port congestion, and the construction of a new port to improve port competitive power. In particular, if a great deal of function in the existing area of Busan Port transfers to a new port, then the problems of port redevelopment will occur as shown in the cases of port developed countries explained hereafter. For Korean ports, port redevelopment in a port zone is implemented for improving the port productivity that targets a local area, but the entire and systematic port redevelopment is not accounted for. Focused on this point, the paper is to present the directions for full-scale port redevelopment of the existing zone of Busan Port. The findings are as follows: First, the region of Busan is divided according to a regional classification that is necessary for port redevelopment. Thereby, 4 zones, total 26 regions of redevelopment were selected. Second, overseas case studies were considered for port redevelopment. From these same studies, appropriate types of port development in Korea were extracted and presented. Third, the status and problems of the selected redevelopment regions were analyzed, and types of port redevelopment were assigned. This study was not applied to the strict evaluation technique by quantitative analysis, but the concept and directions for unprecedented port redevelopment were first defined and established. It is significant to select target areas for redevelopment by regional classification and present directions for developing each region by choosing Busan Port as a real case study. This initiation will greatly contribute to the succeeding study.

The increase of elderly population is inevitable a universal trend in developed countries. The Korea also followed this tendency. Especially the elderly population in Korea has been rapidly increasing since the 1990s. The rural population is aging more rapidly than the urban one because younger generations move into the urban area, due to better jobs and children education's opportunities. However, the majority of studies on population ageing are focused on the urban area rather than the rural ones. Rural areas also have been excluded as a priority of the national welfare policy for the elderly people. This paper tries to analyze the population ageing among regions and to identify the regional disparity between the elderly people and the level of public services in the rural area. Based upon these results, this study notes some policy alternatives for the improvement of quality of life of the rural elderly. It also suggests on the suitable location of public service facilities in the rural areas.

Cities in Korea have rapidly urbanized and they are not well prepared for natural disasters which have been increased by climate change. In particular, they often struggle with urban flooding. Recently, green infrastructure has been emphasized as a critical strategy for flood mitigation in developed countries due to its capability to infiltrate water into the ground, provide the ability to absorb and store rainfall, and contribute to mitigating floods. However, in Korea, green infrastructure planning only focuses on esthetic functions or accessibility, and does not think how other functions such as flood mitigation, can be effectively realized. Based on this, we address this critical gap by suggesting the new green infrastructure planning framework for improving urban water cycle and maximizing flood mitigation capacity. This framework includes flood vulnerability assessment for identifying flood risk area and deciding suitable locations for green infrastructure. We propose the use of the combination of frequency ratio model and GIS for flood vulnerability assessment. The framework also includes the selection process of green infrastructure practices under local conditions such as geography, flood experience and finance. Finally, we applied this planning framework to the case study area, namely YeonJe-gu an Nam-gu in Busan. We expect this framework will be incorporated into green infrastructure spatial planning to provide effective decision making process regarding location and design of green infrastructure.

High-speed trains have been developed widely in European countries and Japan in order to transport large quantity of people and commodities in short time. Additionally, a high speed train is one of the most desirable and environmentally friendly transportation methods. When a high speed train enters a tunnel, aerodynamic resistance is generated suddenly. This resistance causes micro pressure wave and discomfort to passengers. Due to this aerodynamic pressure against the train, a large amount of traction is required for the operation of a train in a tunnel. Therefore, it is essential to incorporate a pressure relief system in a tunnel in order to reduce aerodynamic resistance caused by a high-speed train. A pressure relief duct and a vertical shaft are representative measures in a tunnel. This study represents the effect of pressure relief ducts in order to alleviate positive and negative normal pressures acting on a train. One-dimensional numerical simulations were carried out in order to estimate the effect of pressure relief systems.

The prevalence of nonspecific interstitial pneumonitis(NSIP) in HIV-positive patients with pulmonary disease has varied from 11 to 38%. But NSIP in HIV-positive patients is indistinguishable from Pneumocystis carinii pneumonia(PCP) clinically and radiologically. The number of HIV-positive patients is less in Korea than in western developed countries, so little attention has been paid to the differential diagnosis between NSIP and PCP. We report a case of NSIP in HIV-positive, 61-year-old man which mimicked PCP. He presented with cough, sputum and mild exertional dyspnea. Lung sound was clear. But, chest X-ray and HRCT demonstrated diffuse patch and bilateral ground-glass opacities in central and perihilar area of both lung. Microbial pathogens were not found on sputum, BAL fluid and tissues taken by TBLB. In transbronchial lung biopsy specimen, interstitial infiltrates with lymphocytes were distributed on peribronchiolar regions. A pathologic diagnosis of NSIP was suggested, he received symptomatic treatment. The follow-up chest X-ray showed near complete resolution.
