산업재해의 직접적인 원인은 작업자의 불안전한 행동과 작업과정에서의 안전시설 설치미흡으로 인한 불안전한 상태로와 기술적, 교육적, 관리적 원인의 복합적인 형태로 발생되는데 그 가운데 산업안전보건법상의 건설공사 각 공종 별 기술적인 안전시설설치 기준이 건설업 종사자에게 쉽게 적용하기가 현행 법기준에는 문제점이 있으며 이러한 복잡한 법기준을 분석하여 안전사고 예방 기법에 적용하고자 제시하고자하며, 향후에 이를 바탕으로 산업안전보건법상의 안전기준을 체계적으로 분석하여 제시하고자 한다.

공단 주변 지역에 형성되어 있는 초지 군락의 구조, 종 다양성 및 토양 특성을 조사하였다. 조사지역은 상관에 의해 쑥(Artemisia princeps var. orientalis)군락, 미국자리공(Phytolacca americana)군락, 참억새(Miscanthus sinensis)군락으로 구분되었다. 1999년 8월에 조사한 각 식물군락의 지상부 현존량은 쑥군락 5,645g/m2, 미국자리공군락 2,827g/m2, 참억새군락 9,048g

여천공단 주변 산림지역의 식물군집구조를 밝히고 13년간 변화를 파악하기 위하여 300m2 조사구를 27개소 설정하였다. DCA ordination분석 결과 곰솔군집, 곰솔-참나무류군집, 곰솔-사스레피나무군집, 소나무-곰솔군집, 소나무군집으로 나누어졌다. 5개 군집의 천이경향을 살펴보면 곰솔-참나무류군집, 소나무-곰솔군집은 졸참나무, 상수리나무를 중심으로한 참나무류군집으로 변화될 것이며, 곰솔군집, 곰솔-사스레피나무군집, 소나무군집은 현상태를 유지할 것으로 판단되었다. 5개 군집의 토양산도는 pH 4.38~4.61로 산성토양이었으며, 유기물함량, 치환성양이온(C a++, Mg++, K+)함량은 전국토양의 평균치보다 낮은 상태로 불량하였다. 13년간의 식물군집구조와 토양특성변화를 살펴보면 종수, Shannon의 종다양도, 최대종다양도에 있어 1983년보다 1996년이 높아졌으며, 토양특성도 동일한 경향이었다.

Occurring economic loss of economics by the earthquake, such as Gyeongju and Pohang in Korea, interest in seismic stability of facilities is increasing. Electrical Cabinet Structure in Power Plant should be prepared for malfunctions and its structural safety should be ensured as well an earthquake event. The purpose of this investigation is to increase the seismic stability of the cabinet. Through finite elements analysis, dynamic characteristics of the cabinet were identified herein, and time history analysis was performed by converting the design response spectra. In order to improve safety against earthquakes, a variable analysis was conducted to utilize steel dampers for seismic retrofit of the cabinet, and time history analysis results compared with the response of basic and seismic retrofitted cabinets.

Purpose - The industrial structure upgrading can play an important role in promoting the carbon emission efficiency. Thus, this paper attempts to study the impact of industrial structure upgrading on carbon emission efficiency in order to reduce carbon emissions. Research design, data, and methodology - This paper selects panel data of 30 provinces and municipalities (autonomous regions) in China from 2001 to 2016, and divides them into three regions. The Moore index is used to measure the industrial structure upgrading, the non-radial SBM model based on undesired output is used to measure the slack variable to calculate the total factor carbon emission efficiency. Finally the impact of industrial structure upgrading on the carbon emission efficiency are analyzed. Results - It is found that the Moore index and the carbon emission efficiency in the eastern region is the highest in the three regions. Conclusions - The influence of various influencing factors on carbon emission efficiency is different between regions. The Moore index has a positive effect on the carbon emission efficiency in the eastern region, and has a negative influence coefficient on the central region. The effect on the western region is not obvious.

This study classifies the types of spatio-functional differentiation in Korean island areas and analyses typical characters and suggests the development directions by each type. Eup/Myeon-level island areas are classified as six types by the factor analysis and the cluster analysis. First type is the traditional rural center. This type puts emphasis on maintaining phase as the central space and has to maximize development potential of the whole of settlement zone. Second type is the specialized region in manufacturing industry and the qualitative mutual growth of regional industries is able to be suggested. Third type is the specialized region in the neighborhood service provision. This type needs to devise the plan for utilizing potential customers actively and developing into the region specialized in tourism industry. Fourth type is the specialized region in tourism-support service functions. This type has to promote differentiated policies for maintaining amenity infra or value of countryside capital and preservation and utilization of resources by regional features. Fifth type is the fishing industry-dominated region. This type has to promote sustainable fishery development through the policy reflecting regional features and condition. Finally, sixth type is the sluggish region dominated with the traditional agriculture and fishery. This type is needed to aim at developing into the new food production base having the advantage of clean environment by strengthening support in specialized agro-fishery products. The existing researches on spatio-functional differentiation were mostly discussed with respect to land development, but this study highlights the difference in deal with the island areas distinguished from the condition of industry.

The purpose of this study is to examine the effect of regional ageing rate to industrial structures of rural areas in Korea. This paper shows that there are cause-effect relations between the industrial specialization and ageing rate in 'Agriculture', 'Finance & Insurance', and 'Real Estate & Leasing' sectors. The ageing levels are classified into ageing society, aged society, and super-aged society according to UN standard that cause different impacts on industrial specialization of regions. This paper finds that the industrial specialization is determined by the ageing levels. If there is an increase in ageing rate by 1% in ageing society, the industrial specialization of the three industries could be strengthened by 0.14%. But, ageing rates have negative impacts on the industrial specialization in aged society and super-aged society by 0.76% and by 1.20%, respectively, as increasing ageing rate by 1%. As the ageing rate progresses, 'Agriculture', 'Finance & Insurance' and 'Real Estate & Leasing'sectors have positive impacts on the industrial specialization in the ageing society. But 'Finance & Insurance' and 'Real Estate & Leasing' sectors have changed into negative impacts on the industrial specialization in the aged society. In the aged society, the employment of elderly persons of 'Agriculture' and 'Finance & Insurance' sectors increase by 1% makes positive impact on the industrial specialization by 1.54%, by 0.45%, respectively. The result of this paper can be applied to a significant guideline at establishing regional employment planning such as elderly customized employment, vocational training for rural areas, where above 14% of ageing rate.

This study, in order to complement instability of analysis result stemming from the choice between reference point and comparison point which is pointed out as the defect of shift-share analysis, conducted shift-share analysis using Gross Regional Domestic Product (GRDP) trend of Geumgang area, Chungcheongnam-do for the period from 2000 to 2011. As a result of the analysis, ➀ industries that had both the positive Regional Share Effect (RSE) and Industrial Mixed Effect (IME) were service industries such as manufacturing industry, electricity gas, transportation industry, art, etc., which are positively influencing the regional industry. ➁ industries that had both the negative RSE and IME were other service industries such as wholesale and retail businesses, lodging industry, food industry, real estate business and leasing service, business service industry, public administration, etc., which provide basic livelihood services for the residents. ➂ industries that had the positive RSE and negative IME were agriculture, forestry and fishery industry, mining industry, construction industry, and educational service industry. ➃ industries that had the negative RSE and positive IME were info-communications industry, financial and insurance businesses, health industry, etc.
