Safety assessment of construction projects may be affected by various factors such as types and scale of projects, construction methods, procedure, climactic, and site conditions etc. Presently, in planning and design phases, designers are still often uncertain of their responsibilities, l3i]I information and training of safety. Therefore, designers are still failing to exploit the potential that have to eliminate and reduce risks on site. In this study, the concepts of safety impact assessment is introduced in order to derive the performing design for safety in design phase. For this purpose, a framework for safety impact assessment model using risk-based approach for construction projects is suggested. The suggested model includes of information survey and scenarios, classification of safety impact factors occurred by design and construction, and quantitative estimation of magnitude and frequency. Moreover, the checklist which is enable to identify relationship between safety impact factors and design factors is developed and the methodology of safety impact assessment model using risk-based approach is also proposed.

An Administrative Boundary is the basic of spatial information to cover geographical and regional area. Its importance has arisen in our society at the Smart world era. However, it is difficult to serve exact boundary's lines as administrative boundaries are based on the cadastre lines of land register ; these partly are overlay each other or has gaps. So, it Should be adjusted. But, the maintenance work of administration boundaries causes a conflict or confusion unless we offer concrete procedures and detailed plans previously. Therefore, a rational method is required to prevent side-effects such as confusion, disagreem ent and a conflict etc. In this Study, we present a method and 5 step procedures to make better use in a practical maintenance work. we researched on basic studies of Administrative boundary's concept, history. And we performed a field survey as well as analysis of current problems. considering these results, we suggest usage of various spatial data sources, stake-holders' participation, a method of Nearest district's boundaries to maintain administrative boundaries. Throughout the method, we expect it to serve correct boundary-data to various fields without a big confusion. it is also useful to apply its results not only for re-surveying our land but for recording appropriate boundary-data as rational lines.

The purpose of this study was to investigate the determinants of total payment for mental and behavioral disorders patients admitted through the emergency room. Study data was selected from the Korean National Health Insurance sample data in 2009. This data was consisted of 753 inpatients who are 331 inpatients with only main sick(F31-F39) and 422 inpatients with main sick codes(F31-F39) and sub sick(F00-F99) admitted through the emergency room. SPSS v.18 was used for the statistical analysis such as descriptive analysis, t-test, ANOVA, and multiple regression analysis. In multiple regression analysis, significant variables affecting total payment of main sick patients were gender(p<.01), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). Also, main sick patients with sub sick were gender(p<.01), age(p<.001), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). These findings implied that it is necessary to build short, middle, and longterm program and system for high risk mental and behavioral disorders groups.

A fungal isolate was newly collected from Zoysiagrass 'Anyang-Joongji' in small circular patches on a fairway ofa golf course in Korea, which seriously occurred during the early summer period of 2005. The isolate presented on PDAmedium, named Scz1, was closely identical to Sclerotinia homoeocarpa, a casual fungus of dollar spot disease, in cool season turf grasses such as creeping bentgrass. Hereby, this study was accomplished to characterize the isolate and compare it with the fungus, named Scb1, isolated from dollar spot-infected creeping bentgrass (Agrostis palustris Huds. cv Penncross). On PDAmedium, individual mycelial appearance of three isolates was very similar except for the pigment. Mycelial pigments of Scz1 and Scz2 (another analogous isolate collected) were light pinkish on the reverse side of PDA medium but that of Scb1 was dark brownish. In a microscopic study, three isolates were barely distinguishable in the appearance of mycelia. As expected, in the temperaturesensitivity assay, all pathogens were very delicate to $32^{circ}C$ above but not to $30^{circ}C$ below, in which was explained to be one of typical characteristics in S. homoeocarpa. In an artificial inoculation assay, disease symptoms including leaf spots in Zoysiagrass were appeared within 6-7 days after inoculation through the hand inoculation method with the isolate-infested soil. Then the fungus was re-identified from the infected leaf tissues. Interestingly, inoculation of isolate Scz1 gave rise to distinct symptoms in only Zoysiagrass but not in creeping bentgrass 'Penncross' and Kentucky bluegrass 'Midnight'. The observation might be involved in host specific pathogenecity of S. homoeocarpa Scz1 to Zoysiagrass. In a chemical sensitivity assay for the isolate, Scz1, showed a high mycelial inhibition against two fungicides, iprodione and propiconazole. All results described above suggest that S. homoeocarpa Scz1 is a primary pathogen of Zoysia dollar spot disease.

The purpose of this study is to suggest safety education on life science inquiry activity, which subjects on the exploration and autonomous research to the relevant topics, mainly done by the science high school students. Investigation was made on subjects of research activity proposed from Life science and autonomous research from science high school students by examine thoroughly 2009 revised education curriculum. To prevent school laboratory accidents, education of basic safety regulations and general precautions should be repeatedly notified by clear statements and expression to each topic. Expressing the safety factors considering the themes of autonomous inquiry and activities presented in the course of education should be done, so that students should not experience laboratory accidents by reason of ignorance. From the beginning of organization to performing research, safety rules about disposing chemicals and tools wastes occurring during research should be noticed and expressed in precautions following waste disposal system should be adopted. It is necessary to level up the accessibility of information about the laboratory safety rules to confirm to the every student, and also ensure the takeover of the clean-up and use of utilities at the time of search end in order to prevent the incidence of laboratory accidents during the thorough stages of biological inquiry activities.

Varietal differences on viviparous germination of newly released rice varieties were investigated to provide selection criteria for the high quality rice production. Laboratory and field tests were conducted on 20 different rice varieties in 2007. Varieties which showed below 10% of viviparous germination at the laboratory test were Odaebyo, Hitomebore, Koshihikari, Hwasungbyo, Hopyongbyo, Ilpumbyo, Chuchungbyo when they were treated 35 days after heading (DAH) at the temperature of 25/$15^{\circ}C$ (day/night) for 8 days, and were Hitomebore, Koshihikari, Hwasungbyo, Hopyongbyo under diurnal temperature of 30/$20^{\circ}C$ (day/night). At the field test with artificial lodging, there were 12 varieties including Hopyongbyo, Hitomebore that showed lower viviparous germination below 10% when they were treated at 35DAH and measured 8 days after lodging treatment but there was only four varieties (Ilpumbyo, Hwasungbyo, Chuchungbyo, Hopyongbyo) when lodging treatment was made at the 45DAH. Among newly released rice varieties, viviparous germination rate of Hopyongbyo was below 10% and was 11 to 20% at Hithomebore and Samgwangbyo, 21 to 40% at Koshihikari, Odae-No.1, Josaengheukchalbyo, Chonghobyo, 41 and 60% at Suean-No.1, Whongwangbyo, Bosukchalbyo, and 61 to 90% at Gopumbyo when it was examined 8 days after lodging treatment at 45DAH.

This is the study of efficient security system for candidates for the 17th President. The president election will be held in 20 countries this year. As conflicts between interest groups are expected to emerge, they are afraid of accidental raid in the campaign tour in addition to revival of regionalism and possibility of confrontation between interest groups with issues of anti-FTA In our country. The purpose of this study is to suggest appropriate method through study of security system for president candidate as just 6 months are left for the 17th president election. Also this study covers security environment for the president election, principle of security, and theoretical study for cause of terror, security system domestic and abroad and its analysis and how to provide the efficient security for president candidate. Therefore first, for desirable security the security should be provided by professional org like president security department. Second, combined security for target by current rules should be done. Fourth, total security is necessary to prevent security threats in advance. Third, the public security should be provided for every president candidates. Fifth, example of secret service in America should be studied and economical security should be considered Sixth, we should increase the use of Security Company and martial artists.

This paper explores the historical process that created a specific understanding of and responses to atopic dermatitis(AD) in Korea. AD hardly has a status of an environmental disease in other societies but it is a representative environmental disease in South Korea in connection with various environmental pollutants, most notably with endocrine disrupting chemicals. This understanding of AD as an environmental disease led to an unprecedented legislation of the Environmental Health Act of 2008, a broad environmental health law with the precautionary principle and the focus on human aspect of environmental problems. In line with the growing body of works that articulate the roles of the public and culture in regulatory process, this paper argues that both the understanding of and the regulatory responses to AD owe greatly to the knowledge and political practice of the public, especially that of the 'Atopy moms'. Their knowledge practice that creatively appropriated scientific uncertainty regarding AD brought unexpected epistemological and political alliances, respectively with alternative medicine and with organic coop movement and an emergent political party and generated enough dynamics for the legislation of the EHA.

Over the last 10 years, the fight against occupational diseases of semiconductor workers led by SHARPS(the Supporters for the Health And Rights of People in the Semiconductor industry, NGO) has accomplished considerable achievements, especially in the legal and institutional aspects. First, the court and the government accepted the claims that 24 injured workers respectively filed, recognizing their 10 types of diseases as occupational illness. The court not only expanded the list of work places and diseases that it recognized, but also presented more progressive logic of recognition. The most remarkable achievement among them is the case ruled by the Supreme court in July, 2017. In terms of 'worker's right to know', which is the most important factor in preventing occupational diseases, there have been significant legislative bills, court rulings and government guidelines. The revised bill of the Industrial Safety and Health Act to strengthen workers' rights to know and to introduce the pre-review system on trade secret is currently under review by the National Assembly. The court recently ruled that the government should disclose its inspection results on safety and health management at semiconductor factories. The ministry of labor has drawn up internal guidelines to more actively open its safety and health data to public. This study looks over recent developments in such rulings, bills and guidelines and then, analyzes their implications, laying the groundwork for future actions for worker health in the electronic industry.
