This paper studies on the optimum design space of solar power plant, application of efficiency improvement facility using various examples, lack of power cost, lack of land development and difficulty of permission. We analyze economic factors and profitability by deriving analysis factors according to the conditions of construction examples and variables by applying efficient facilities that can utilize idle space of individuals and public more efficiently through various cases.

This study examined the effect of housing cost burden on the intention of moving into public rental housing. For the empirical analysis, I used the 2019 Korea Housing Survey and divided the households based on housing tenure and income level and they are as follows: homeowners, renters and low income, middle income and above. As analysis method, the binomial logit model is used and the empirical analysis shows that the burden of housing costs was increased the intention of moving into public rental housing even in homeowners and households with middle income or higher.

With the increasing demand for office space, there have been questions on how office rent distribution produces a change in the urban spatial structure in Seoul. The purpose of this paper is to investigate a relative price gradient and to present a time-series model that can quantitatively explain the dynamic changes in the urban spatial structure. The analysis was dealt with office rent above 3,306 m² for the past 10 years from 1Q 2010 to 4Q 2019 within Seoul. A modified repeat sales model was employed. The main findings are briefly summarized as follows. First, according to the estimates of the office price gradient in the three major urban centers of Seoul, the CBD remained at a certain level with little change, while those in the GBD and the YBD continued to increase. This result reveals that the urban form of Seoul has shifted from monocentric to polycentric. This shows that the spatial distribution of companies has gradually accelerated decentralized concentration implying that the business networks have become significant. Second, contrary to small and medium-sized office buildings that have undertaken no change in the gradient, large office buildings have seen an increase in the gradient. The relative price gradients in small and medium-sized buildings were inversely proportional among the CBD, the GBD, and the YBD, implying their heterogeneous submarkets by office rent movements. Presumably, those differences in the submarkets were attributed to investment attraction, industrial competition, and the credit and preference of tenants. The findings are consistent with the hierarchical system identified in the Seoul 2030 Plan as well as the literature about Seoul's urban form. This research claims that the proposed method, based on the modified repeat sales model, is useful in understanding temporal dynamic changes. Moreover, the findings can provide implications for urban growth strategies under rapidly changing market conditions.

현대의 고도화된 산업발달과 함께 생산품의 고품질, 다품종, 대량생산을 위한 설비의 대형화, 공정의 복잡화, 위험성이 높은 물질의 대량 사용 등으로 인하여 잠재위험이 더 한층 증가하게 되었다. 따라서 산업현장에서 여러 가지 잠재위험으로 인하여 화재, 폭발, 독성물질 누출 등 대규모 중대산업사고의 발생 가능성이 커졌으며 사고 발생시 현장의 근로자, 인근지역 주민, 주변의 환경에까지 막대한 영향을 미치게 된다. (중략)

경제 및 산업구조를 근대화시키기 위한 정부의 중화학공업 육성정책에 의해서 발전을 지속한 국내 화학공업은 선진국보다는 20∼30년이 늦은 60년대 말부터 본격적으로 시작되었다. 1960년대 이후 이러한 화학공업의 발달은 산업발전에 획기적인 전기가 되어 신흥공업국으로 발전하는데 중추적인 역할을 하였다. 그러나 각종 공정 설비의 규모가 증가하고 유해한 화학물질의 사용이 크게 증가함에 따라 대형사고의 위험성도 더 한층 증가하게 되었다. (중략)

현대의 화학공장에서는 소비자의 요구를 충족시키기 위한 생산품 생산 및 제품의 고급화, 규격화 등으로 인하여 공정 및 설비가 더욱 복잡해지고, 공정운전조건이 세분화됨으로써 고온, 고압에서 사용·취급·저장되는 유해화학물질의 특성으로 인하여 대규모의 잠재 위험성이 증가하는 현실이다.(중략)
