China infrastructure construction market has huge potential for increased use of PPP/BOT mode and one of the most attractive markets of doing business. However, there are still a multitude of challenges for overseas EPC contractor to enter into the China PPP/BOT market both internally and externally. Especially, the construction legal system and relevant policies are considered at present the biggest barriers in accessing China construction market. Therefore, the main purpose of the paper is to identify the impact of the construction laws, regulations and BOT-related policies on the viability of foreign contractor-led BOT project in China. To the satisfaction of the purpose, this paper will first analyze China construction laws based on the key issues that must be tackled by foreign EPC contractor before they enter into China. This summary gives the possible contract scheme for a BOT project of interest in which foreign contractors could define the scope of works and measure the viability of the project. Finally, a case study of wastewater treatment plant BOT project in China subsequently illustrates some of the lessons learned from the foreign contractor's perspectives for successfully participating in future environmental market in China.

Article 64 of the Enforcement Decree of the National Contract Act The requirement of the pre-amendment statute related to the adjustment of the contract price was 5% or more of the price fluctuation rate from the date of the contract. However, the meeting requirement was changed from 5% or more to 3% or more from the date of signing of the Presidential Decree No. 19035 to 2005. 9. 8. The method of adjusting the contract amount was also changed to determine the contractor's desired adjustment method at the time of contract. Alleviating these requirements and revising the empowerment of contract partners is intended to prevent difficulties in achieving smooth objectives by applying to public construction contractors without unfairly benefiting or unfavorable to contract partners. Even if the standards are relaxed and the rights are secured as described above, if the existing provisions for the adjustment of price fluctuation are applied, unlike the original purpose of the government system, the Korea Bank's price economic statistics classification method and the contract construction classification criteria applied in public construction work Due to the inconsistency, it can be seen that the amount of adjustment for price fluctuation by construction type is excessive and underestimated. Therefore, the purpose of this study is to analyze problems through cases and to make appropriate construction cost adjustment through improvement measures.

Recently, in Korea, various technology developments have been made to utilize 3D space and facility data such as unmanned aerial vehicles (UAV) and laser scanners with the goal of improving productivity at construction sites. However, the lack of related regulations for 3D laser scanner surveying has been a barrier to using the technology across the surveying industry. As a result, owners, contractors, and construction supervisors are reluctant to introduce and apply technology to the site. In this study, the guidelines (drafting and inspection work to be supervised by construction supervisors when constructing earthworks using laser scanners) was developed and presented so that the earth surveying and quantity calculation technology using a laser scanner could be applied and diffused in a construction site. Through the development of this guideline (proposal), it is judged that the supervision and inspection of earthworks quantity using a laser scanner will be activated in the field.

Building construction Is essential part that we get the enjoyment and promote the quality in human life. But construction process itself has an bad effect on environment: air Pollution, water Pollution, soil Pollution ,etc. These day, Air-environment management becomes very important part in Construction because Construction duration delay which is caused by civil petitions related air-environment occurs frequently. For developing the management-guideline of environment management, This study suggests an executive management-guideline based on surveying air-environmental related laws, regulations and literatures, making out important factors. With the management guideline, The Purpose of this study is to make an air-environmental management system through that Process.

During five years (Year 2009~2013), Total victims of 72 %(81,560 people) and those 50.6 %(1,258 people) of death accident occurs in small scale construction site which operate 2 million USD less construction budget. Especially, falling death accident account for 785 people, in the share of 33.2 %(261 people) death disaster takes due to defect of original cause materials. The major safety issues in small scale work place take place while scaffold installation, disassembling, work-plate improper installation or non-professional skills of workers. Furthermore, labor subcontract systems make small construction site shortage of resources. Those workers regard work-plate as unnecessary and consumables supplies. Because of that most of workers use unsafe workplace in most construction site. Therefore, in order to prevent falling accident occurring in small scale work site, government should organize related regulations such as "Work site safety construction method" and then expands education support, financial aid, and sourcing safety supplies for work plate which offer broad variety experiences. Also, introduce certificate solutions for various work plates to improve safety function such as anchoring type method and anti sliding function.

We show results that examine about electrical properties of XLPE insulated 6.6kV cable termination by mechanical damage. The cable used to produce the cable termination is 6/10kV tray XLPE fire retardant electric cable (6/10kV TFR-CV $35SQMM{\times}1C$) which is domestically made. We apply force to XLPE insulator and made mechanical defect using knife. Defected samples go through the withstand voltage test according to the IEEE std. 48 test regulations and lighting impulse (hereunder, IMP) withstand voltage test regulations. Then the effects of the scars shown during the construction process on electric accidents at the end part are analyzed.

Product liability(PL) is the producer's compensation to customers for damage incurred by product defects. This paper studies on the organizational culture, promotion process, system construction, system level, product safety review, product safety assurance, system operation, and its effectiveness and necessity of recognition for the PL system of small and medium-sized firms in Gangwon-Do province. The results show that the firms have product safety regulations, but the number of firms which its employees understand the regulations is less than the number of firms which do not understand. Also the number of firms which is preparing PL prevention and insurance, and counterplan for accidents seems to be not in large numbers.

Effect of hand-transmitted vibration on human discomfort and health was reviewed. Since the effect by hand tool was more serious than those by any other vibration environments, western countries have protected hand tool workers by regulations. International organization for standardization legislate standard, ISO 5349, at 1979 for the measurement and evaluation of the effect. Afterwards, more than twenty standards on hand-arm vibration were enacted to Protect any damage of hand tool users. Even though Korea Standards adopted ISO 5349 in 2001, it is required an action plan should be applied to all of work environments, especially to the workers using pneumatic tool workwers such as miners, construction workers, and etc.
