This study aims at establishing a sizing system required for producing ready-made clothes which can fit the body shape of disabled men using wheelchair. It measured the bodies of 178 adult men using wheelchair and compared the sizing system of German adult men using wheelchair (1984) with KS system(KS K0050, 2004) in order to establish standards of the sizing system. AS a result, in terms of classification of body shapes, KS system cover more types of disabled men's body shapes and especially, A types (Drop 15.6) showed the widest coverage with 32%. In classification of heights, the widest range of height was 170 cm, and Korean men's four sizes between 158 cm and 176 cm covers 88.2% of disabled men's body shape. For chest size, 91.1% of disabled men's chest sizes were included in seven sizes, which are 4 cm intervals between 88 cm and 112 cm with 100 cm standard. In consideration of the ranges of height and chest, the general sizes (A types; 11 sizes, B types; 3 sizes, Y types; 5 sizes) are selected to present the standardized measurements. Basic parts of the upper garment sizing system for disabled men using wheelchair were height-chest-waist size.

IEC 60079-10-1 edition 2.0, the global standard for hazardous area classification, was newly revised in 2015. There are many differences compared to the previous edition 1.0 version, first released in 2008, so it has caused confusion in the industry. In case of edition 1.0, the hazardous area extent can be derived through the mathematical formula, but in case of edition 2.0, there was the problem that the exact hazardous area extent was not known because of the mathematical formula of the plot for applying the hazardous area extent was not presented. In this study, we converted the plot introduced in edition 2.0 to CAD format and derived the plot as the mathematical equations. Through this, we suggest the hazardous area extent formula of three states (heavy gas, diffusive, jet). As the IEC committee did not provide the mathematical formula of the hazardous area extent according to the release characteristic, it is impossible to apply the exact hazardous area extent. In this study, a mathematical approach was derived for the plot introduced in edition 2.0, which can reduce the confusion of the applying hazardous area extent.

Daejeon, encompassing Daedeok Science Town and Daedeok Innopolis, possesses the advantage of portraying relatively higher regional innovation capacity and facilitating network formation among regional professional research organizations. Applying the Social Network Analysis(SNA) techniques, this paper focuses on divulging structural and spatial characteristics of the Daejeon Information and Communication(ICT) industry network, analyzing co-research projects implemented by the Daejeon-based universities. For the analytical tool, it depends on NETMINER 3.0. Furthermore, based on the Systems Thinking approaches, this study suggests a couple of policy implications. Judging from the Korea Standard Industrial Classification principles, the existing ICT industry is subdivided into 11 sub-industries. The highest degree centralization value comes from the Mobile Communication sub-industry(188.668%), indicating that Mobile Communication sub-industry exerts the most significant impact on the regional innovation networking in Daejeon. Among various stakeholders, Korea Advanced Institute of Science and Technology(KAIST) records the top ranking in most categories, conspicuously leading the institute-industry linkage. In terms of the ICT spatial distribution, the intra-regional cooperation examples present the strongest linkage values, followed by Daejeon-the Capital Region ones. Finally, as well shown in a series of causal loop analyses, this study recommends that Daejeon should put top policy priority in strengthening the internal ICT network within Daejeon proper. Here, Daejeon should keep in mind the fact that there exist reinforcing loops between Daejeon's attractiveness and the entering of new ICT firms.

Construction industry is faced with the problems such as the quickly changeable circumstance and increasing construction companies due to regulation mollification of company registration. In order to overcome these problems, new estimation system based on historical estimation cost is ready to introduce by government step by step. But the time of transition for estimation system causes another problems such as chaos addition to simultaneity of a standard of estimation system and new estimation system, lack of related regulation, accumulation of historical extensive cost data, and adjustment methodology when historical estimation data is applied to next projects. The purpose of this study is to suggest the change factors by activities for estimating historical cost for apartment housing projects. New estimation system is based on historical construction data. For application of this system, the standard adjustment methodology system is necessary. and extensive cost data should be accumulated under an unified construction work classification system. Therefore in this study, according to the construction work classification system, every apartment housing project was classified to 16 work classifications, and 7 major composed items which occupy more than 85% of construction costs are analyzed by detailed activities and by average ratio and maximum ratio each of them. In the result of the study, furniture work, foundation work and masonry work are the works which have big gap of costs between average ration and maximum ratio. In addition to suggestion of change factor by work species, 5 qualified construction specialists are interviewed and change factors in 7 major works are analyzed.

Background: The goal of this study is to develop a general population job-exposure matrix (GPJEM) on asbestos to estimate occupational asbestos exposure levels in the Republic of Korea. Methods: Three Korean domestic quantitative exposure datasets collected from 1984 to 2008 were used to build the GPJEM. Exposure groups in collected data were reclassified based on the current Korean Standard Industrial Classification ($9^{th}$ edition) and the Korean Standard Classification of Occupations code ($6^{th}$ edition) that is in accordance to international standards. All of the exposure levels were expressed by weighted arithmetic mean (WAM) and minimum and maximum concentrations. Results: Based on the established GPJEM, the 112 exposure groups could be reclassified into 86 industries and 74 occupations. In the 1980s, the highest exposure levels were estimated in "knitting and weaving machine operators" with a WAM concentration of 7.48 fibers/mL (f/mL); in the 1990s, "plastic products production machine operators" with 5.12 f/mL, and in the 2000s "detergents production machine operators" handling talc containing asbestos with 2.45 f/mL. Of the 112 exposure groups, 44 groups had higher WAM concentrations than the Korean occupational exposure limit of 0.1 f/mL. Conclusion: The newly constructed GPJEM which is generated from actual domestic quantitative exposure data could be useful in evaluating historical exposure levels to asbestos and could contribute to improved prediction of asbestos-related diseases among Koreans.

본 연구에서는 표준통계분류체계 간 연계를 통해 산업 혹은 제품의 내수 시장규모를 추정하는 방법을 제안하고 실질적 활용 가능성을 타진하였다. 이를 위해 KSIC 분류로 조사된 통계청의 광업 제조업 조사 결과와 HS 분류로 조사된 무역데이터를 통계청과 UN 통계처에서 제공하는 연계표를 활용하여 연계하였다. KSIC-ISIC-HS 간 통합연계표를 이용하여 국내시장규모를 분석하는데 있어 가장 큰 문제는 분류체계 간 중복 연결 문제인데, 본 연구에서는 각 품목별 출하액과 무역액 사이에 강한 상관관계가 있음을 활용하여 출하액의 상대적인 비중을 가중치로 중복 연결된 HS 무역액을 배분하는 방법을 제시하였다. 이를 이용하면 제조업 분야의 총 125개 모든 ISIC 품목별 국내시장규모를 분석하고 이를 바탕으로 미래의 단기 시장 규모를 예측할 수 있다. 본 연구에서 제시한 방법은 ISIC 분류보다 세분화 된 품목에 대한 분석의 한계, 제조업 이외의 분야에 대한 적용 한계, 출하액 결측치로 인한 오차 등의 한계가 있으나, 내수 시장규모 정보를 가장 객관적이고 신뢰성 있으며 지속적으로 활용 가능한 데이터를 이용하여 분석 제공할 수 있는 방법을 제시한 점에 본 연구의 의의가 있다.

For the advance of Korea's ready-made clothes industry into China, we need some information about the body types of the Chinese and the sizes of ready-made clothes. The purpose of this study is to prepare basic data about the reality and process of the size establishment of clothing sizes in China. The conclusions are as follows. 1. Clothing size establishment was made three times in 1981, 1991, and 1997. At present, the version of 'GB/T 1335-1997 Size' is used. 2. 'GB/T 1335-1997 Size' is composed as follows. \circled1 Based on the drop values of chest girth and waist girth, 4 (Y. A, B, C) body types of adult men and women were chosen. \circled2 Sizes contains Ho and Hyoung, 'Ho' refer to height (cm) and serve as the standard of length, while 'Hyoung' indicate chest girth (cm) and act as the standard of girth. \circled3 The size divisions of the 3 basic items for adults are 5cm (height), 4cm (chest girth), and 2cm (waist girth). So they are named '5ㆍ4, 5ㆍ2 size series', \circled4 For grading in dress production, approximate values to the means of the 2 basic items are called 'center types'.\circled5 Other necessary items for clothing design besides 3 basic items are named 'control items'. \circled6 For babies, children, and adolescents, no body type classification is established. Instead, size series are established according to body height.
