PURPOSES: This study is to suggest the Contribution of Road Capital in Industry and Optimal Level of Road Investment in South Korea METHODS: Based on the literature review, This research is empirically estimated using disaggregate and disaggregated data composed of 10-sectors covering the entire korea economy for the period 1970~2000. The relevant policy questions addressed in this report are : cost reduction and Scale elasticities of road, effect of road capital stock on demand for labor, capital and materials, marginal effect of road, industry TFP growth decomposition, Net Social Rates of Returns, optimal of road capital. RESULTS : The marginal benefits of the road capital at the industry level were calculated using the estimated cost elasticities. Demand for the road capital services varies across industries as do the marginal effects. The marginal benefits are positive for the principal industries. This suggests that for these industries the existing stock of road capital may be under supplied. CONCLUSIONS: This results emerges is that the ratio of the optimum to actual road capital, measured by road, was high at beginning of the period 1970s and declined 1990s. There appears to be evidence of under-investment in road capital. That is continuous and premeditated investment for road which lead to saving time and finance.

This paper describes pop stars' fashion style by the changes of pop music from the 1950's of the formative Period of a rock-n-roll to the 1990's. The author could examine the features of pop music as follows : the 1950's rock-n-roll, the 1960's rock and Psychedelic rock. the 1970's punk rock, the 1980's new wave and the 1990's reggae·hip-hop. Based on the examination, the author could do sampling of the fashion style, on which current pop music had influence, by rock style, new wave style, and reggae hip-hop style. The rock style makes appearance again as a new style when it is recently accepted to be a fashion. The 1960's hippie, which contains long-cherished desire of antiwar and peace after September 11, 2001 Attack on America and the Afghan War. reappeared as luxurious hippie, and the hybrid punk has been made because barriers between cultures have been collapsed to mix items and combine contradicting components at fashion field. The new wave style destroys sex difference of clothes. and men's clothes style has introduced women's dress style, so that androgynous style, which has handsome boy image with womanlike hair style and makeup, and the lingerie style without distinction of underwear and outer garment has made appearance through new cloth wearing ways and overexposure. The reggae and hip-hop style makes appearance to overcome social strata, groups, ages, regions and gender, etc and become one of the 21s1 century culture codes. In conclusion, pop music have played very important roles until expansion and popularity of new fashion style, and has been quickly expanded by mass media development. When the pop music fashion styles are introduced to high fashion, fashion styles have become more polished and high-qualify to expand them at main fashion world again.

Cathodic protection was first introduced as a technology for preventing the corrosion of metals in seawater and underground environments in the early 19th century, eventually leading to the introduction of cathodic protection to the reinforced concrete technology sector in the 1970s. In the 1990s, it was demonstrated that the effectiveness of corrosion protection had increased through a number of developments and studies. Recently, cathodic protection was applied to some reinforced concrete structures and has gradually expanded in scope in South Korea. Technical expertise is necessary to understand the underlying electrochemical principles and also because cathodic protection is important for normal physical maintenance. Therefore, in this study, we introduce the technical details and examples of applications of the cathodic protection of reinforced concrete, including the basic theory, principles, and other criteria.

The first geophysical technique applied to the agricultural sector in Korea was electrical resistivity sounding and conducted in purpose of groundwater exploitation in the 1970s. According to the diversity of agricultural activities since the 1990s, various geophysical methods including electrical resistivity, electromagnetic induction, and self-potential method were applied to several agricultural fields such as soil characterization with saline concentration in vast reclaimed area, delineation of seawater intrusion regions in costal aquifer, safety inspection of embankment dikes with leakage problem, detection of ground subsidence from overpumping and tracing of groundwater aquifer contamination by leachate from livestock mortality burial or waste burial site. This paper introduces representative geophysical techniques that have been utilized in various agricultural fields and suggests several ways to develop the geophysical methods required for the precision agriculture field in the near future based on the past achievements.

The daily intake of dietary fiber by Korean population in urban and rural areas was computed from an optimized food intake based on national nutrition survey, food balance sheet, and the dietary fiber content of Korean foods. The average intake of dietary fiber the nationwide and in urban and rural areas were 24, 22 and 28g in the 1970's, 20, 21 and 20g in 1980's , and 22, 22 and 21g in the 1990's , respectively. As compared with the recommended dietary allowance of 20-25g for Koreans, the average intake of dietary fiber was within the normal range, regardless of urban and rural areas. Since the dietary pattern of korean people is being changed according to different life style, the exact intakes of dietary fiber by diverse specific population groups should be assessed in the future.

This research attempts to describe and explain the development of Korean environmental movement. It finds that the emergence of Korean environmental movement was constrained by the authoritarian nature of Korean politics. In 1970s, environmental movements were primitive and were not organized ones. With the wake of democratization in the 1980s, Korean environmental movement began to get some momentum. And in the 1990s, environmental movement to save clean water has achieved some success in certain areas. However, the emphasis on the growth of local economy in the age of local autonomy system has brought heavy degradation of local environment. The coming of the phenomena of Globalization and Cyber-Age has brought positive effects on Korean environmental movement.

Objectives: This paper aims at addressing the importance of community-based health promotion. It would identify the origin of community health programs in Korea, which emphasized community involvement. And it would reveal the discontinuity of community-oriented health programs in the current health promotion activities. Finally, the methods of attaining community-based health promotion would be suggested. Results and Conclusion: Community-based health promotion had been implemented in rural areas by medical schools in the 1970s and 1980s, which emphasized the role of village health workers. But their roles has disappeared since the government-initiated health promotion policies and programs have been implemented in the mid-1990s. This paper addressed the factors contributing to this discontinuity, such as the expansion of heath insurance system, the change of health care discourses, the monopoly of resources for health promotion by government, and the bureaucratic approach to health promotion, etc. This paper suggested the utilization of voluntary and civic organizations in community for realizing the goal of community-based health promotion.

This study analyzed the fabrics of Chima, Jeogori of the 20th century. It was based on Kyungwoon Museum relics, newspaper articles and photographs. This research focused on the transition process that has been organized into three stages. The first stage is from the opening of a port to the colonial period in Korea. By this time, the casual wear Hanbok was made with the traditional cotton and woolen textiles in addition to quite a lot of upscale clothing textiles. Stage two is from 1970s to the period after the liberation and Western Costumes represent the time of when the suit was mixed. At the time of the war, due to social and economic difficulties, convenience and practicality were emphasized rather than focusing on aesthetic characteristics. Third period is from the 1980s to the 1990s when the Hanbok was no longer considered a casual wear. Instead, its high quality and elegance redefined it to be a formal wear.

This paper evaluate and compare effectiveness of urban growth management measures in Korea using system dynamics model. Simple urban dynamics model was used to compare urban growth management measures. Since the late 1960s, Korean government has been implementing various urban growth management measures without much success. In the 1960s, factories, universities, and public agencies were strongly encouraged to move out to local areas. During the 1970s, regulations on greenbelt area was adopted to prevent urban sprawl. Besides, regulations to prevent location of population inducing facilities, and promoting dislocation of those facilities were implemented simultaneously. During the 1990, regulations on total number of factories in the metropolitan area, development fees were adopted. These various method of urban management were compared. Simulation results shows that promoting decentralization of population, preventing population immigration, expanding greenbelt area are effectiveness ones compared to controlling total number of population inducing facilities, and preventing construction of new industries. Some implications of the findings were discussed.
