This study aims to analyze the on-site improvement area of residential environment improvement project based on research results derived from the on-site and questionnaire survey in case of Daegu. The main findings are as follows. First, residents complain about delay of project completion because a long time has been passed after on-site improvement area was designated. Experts and government officials agree that a new method of development is required. Second, future development should discriminate on-site improvement area according to its level of project completion. The area should be classified into project completion areas and on-going area, and new methods, such as redevelopment, apartment-housing construction method, should be allowed. Third, for better management of on-site improvement area, laws and regulations must be ready and government's will for improvement is crucial.

Risk-based railway safety management has been mandatory in Korea as by relevant laws and regulations enacted since the Railway Safety Act 2004. In particular, the Railway Vehicle Safety Guidance came into effect on Jan 1, 2008 specifies the details of methodology for hazard analysis, risk assessment and safety verification and validation. Fundamentals for success of the risk-based safety management are systematic hazard identification and risk assessment by use of reasonable risk assessment criteria, but the principle of risk-based safety management has not been applied in an effective way to introduction and maintenance of railway vehicle systems because definite risk assessment criteria have not been set down for each railway system or railway network. The purpose of this study is to suggest a risk matrix development principle for risk assessment of domestic urban metro vehicles by analyses of relevant rules and railway operating environment of Korea.

With the increasing use of tower cranes higher than free standing height, the importance of lateral support is also growing. Since the fall of 43 tower cranes hit by the last typhoon 'Mami' in 2003, regulations and concerns about safety of construction equipment have increased and construction laws regarding lateral support have been strengthened. In Korea, where there are many large-scale apartment housing construction works with the development of new towns, Rope Guying is a more economical construction method than Wall Brace which fixes building structure like building wall and slab. The safety of this Rope Guying is not verified and many construction works are still carried out based on the experience of site managers. There has been no case of construction work where frame and measurements are applied. The objective of this study is to examine the safety of Rope Guying method and ensure the effective implementation of equipment and prevention of disasters.

Ninety percent of an average Chinese manufacturer's time spent is on logistics. Therefore, logistics presents the greatest challenge for multinational companies conducting businesses in China. Although more than 18,000 registered logistics companies exist in China, 85 percent of their revenues are generated from basic trucking and storage services. These facts indicate that China will need increasing presence of high-quality foreign 3PL providers, who are able to provide sophisticated IT systems, industry/operational expertise, standardized operating processes, and international networks, compared to their Chinese counterparts. However, they are facing complicated array of laws and regulations as well as difficulty of finding qualified people to fulfill these needs. There are a number of foreign 3PL providers engaged in China's logistics sector to reap a huge opportunity. Nevertheless, many 3PL foreign providers are still cautious about making large investments. Thus they arelooking for alliances that can provide complementarities instead. Another salient feature of strategy is to take over the transportation assets and warehousing of major Chinese manufacturers and distributors.

To address global climate change, various governments are investing in electric vehicle research and, especially in Korea, the application of electric vehicles to public transportation. The lithium batteries used in electric vehicles typically have an expected life cycle of 2-5 years. If electric vehicles become commonly used, they will generate many discarded batteries that could be harmful to the environment. Additionally, lithium batteries are potentially explosive and should be handled appropriately. Thus, reverse logistics issues are involved in handling expired batteries efficiently and safely. Reverse logistics includes the collection, recycling, remanufacturing, and discarding of waste. This study developed a reverse logistics process for electric vehicle batteries after analyzing the as-is process for lead and lithium batteries. It also developed possible disposal regulations for electric vehicle batteries based on current laws regarding conventional batteries.

This is study on the changes of the Apartment House Managerial Problems to grope for the way of more practical management about increasing the apartment house in Korea. The documentary research method was used for this study and the Han-Kook newspapers (1954-1991) was used as an analysis data. On the basis of it, we examined the changes, such as the number of whole articles by time series and the column of head title. We also classified it into several subjects and analyzed it. Finally, we attempted to divide an chronological section on the Changes of the Apartment House Managerial Problems. On the basis of this study, we expect that various documents, related laws and regulations will be analyzed in no distant future. These is going to make the Apartment House Managerial Problems gave more systemic and efficiency.

Remodeling is not subject to strict laws or regulations for permission procedure and structure safety inspection compared with new construction. Most of building owners do not recognize the importance of structural safety enough and place an order to small unlicensed construction company. As a result, important structural materials are damaged without enough investigation into permitted durability and fixed weight and load weight increase. This study suggests a system that can evaluate the state of the building and enables fast judgment on needs of repairing or strengthening as well as needs structural examination.

In order to promote the domestic aircraft manufacturing industry, this study analyzed the limitations of the preceding study on the WTO dispute concerning civil aircraft by summarizing the latest developments and issues in the mid-range aircraft dispute between Brazil and Canada and the large civil aircraft dispute between the United States and the EU. Based on the results of the study, we should look closely at WTO regulations and existing cases of disputes to find maximum support measures, and we believe that in order to stimulate the domestic aircraft manufacturing industry, we should refrain from publicly specifying support measures in the data, such as laws and policies, utilize the WTO SCM Agreement exceptions, and strengthen links with international cooperation and other industries.

This paper shows a reasonable design standard of substation facility density and demand factor in office buildings, that was made by the systematic and statistical way considering actual conditions, such as investigated electric equipment capacity, electric power consumption, etc for 121 buildings. The saving of electric equipment investment, the decrease of power loss, the improvement of facilities utilization and the decrease of electric power rates an be contributed by the application of the design standard must be applied by the revision of current regulations and laws.

The flash point is an important property and hazardous index of a flammable liquid. The flash points are used by virtually all the environmental, health, and safety organizations in both government and industry to classify flammable liquids for safety and transportation regulations. The basics of all flash points behavior are concerned with the vapor pressure and explosive limits. The flash points of pure components and the mixture of solvents can be calculated with the use of the laws of Raoult, Dalton and Le Chatelier. In this paper, experimentally determined lower flash points of a p-xylene and epoxy resin system were compared with the calculated values by using Raoults law. Calculated lower flash points were in reasonable agreement with the observed values.
