The purpose of this study is to analyze subjective and objective factors for the successful operation of One-Person Creative Firms and find significant variables in accordance with the sales and net profit that are representing business performances. Additionally, we were trying to find that what One-Person Creative Firms have had a government assistance need the supports in order to achieving a good performance in sales and net profit. In the result of this study, the sales volume is related that two(2) subjective(Judgment, Planning) and four(4) objective factors(Patent Application, Patent Registration, Business Duration, Initial Capital). The net profit is related that Challenging Spirits in subjective factors and Run-up to the Business, Business Duration, Initial Capital in objective factors. Ultimately, these factors are important variables for the sales and net profit in relationship both the positive(+) and negative(-). This is an exploratory nature of the study rather than the rigorous hypothesis testing. Therefore, a rigorous hypothesis test study model to derive a more detailed study is needed based on the results of this study in the future. 본 연구에서는 1인 창조기업의 성공요인을 주관적 요인과 객관적 요인으로 분류하여, 대표적인 재무적 성과인 매출액과 당기 순이익에 유의한 영향을 미치는 변수들을 분석하고자 한다. 특히 정부지원을 받은 1인 창조기업들이 좋은 경영 성과를 내기 위해서는 어떠한 요인들이 필요한 것인지, 혹은 집중해야 하는지에 관하여 연구하였다. 연구 분석 결과, 매출액에는 주관적 요인 2개(판단력, 기획력)변수와 객관적 요인 4개(특허출원건수, 특허등록건수, 사업 지속 기간, 초기 자본금) 등 총 6개 변수가 유의한 영향을 미치고, 당기순이익에는 창업자의 주관적 요인 중 도전 의식의 변수와 객관적 요인 중 사업 준비 기간, 사업 지속 기간, 초기 자본금 등의 요인이 유의한 영향을 미치는 것으로 나타났다. 결국 이러한 요인들이 정(+)과 부(-)의 관계로써 매출액과 당기순이익에 대한 중요한 요인으로 나타났다. 향후, 본 연구 결과를 바탕으로 보다 세밀한 연구 모형을 도출하여 엄격한 가설 검정의 후속 연구의 필요성이 요구된다.

The summer of 2018 was hotter than any recent years. One of the reasons for this is due to the heat coming out from the atmosphere of the earth and exhaust heat generated after cooling the building inside, which are trapped without going out from the urban area. The heat does not disappear even in evening so that the number of continued tropical night has increased every year. This phenomenon is expected to rise not only in this year but also coming years without decline. It is important to make buildings and cities to have more green space. In addition, it is also important to absorb or convert urban heat to other energy sources by external walls, which are available in more than four sides of building in cities. Thus, the replacement of existing walls into an external wall system that can absorb or convert urban heat would produce a great social and economic value. In this regard, this study aims to derive a development image of external wall system that collects urban heat and convert heat to electric energy through collaboration with other fields such as new materials that can be combined with building sectors in material fields although those materials are not widely used in current building materials. The proposed external wall system integrates three layers including current-flowing panels propose. This study also proposes a building shape mounted with the external wall system. First, national and international study trend on external wall system that can absorb and convert urban heat and quantitative studies on the current patent status were conducted. Second, the study scope is set through the term definition of the external wall system and the number of the layers was set to three. Third, the core technology that can assign the functions to three layers in the external wall system was found from other field. Fourth, the combined image of the external wall system was proposed by fusing three core technologies, and building image mounted with the external wall system was also proposed. This study derived the development image of the external wall system that collected urban heat and converted the heat into electric energy by utilizing element technologies that were developed in fields other than architecture through patents and previous literature reviews. This study also derived a building image mounted with the external wall system that integrated three layers including current-flowing panels. A prototype for this system is not yet developed, and the system is proposed to be viable only theoretically, which is a limitation of this study. However, this study is planned to conduct a performance evaluation on the system after fabricating the prototype by 2019.
3D Infill을 활용한 PC 모듈러공법과 기존공법과의 시공프로세스 비교 연구

In accordance with changes in the domestic construction environment, interest in off-site construction methods (factory-manufactured construction methods) including modular construction methods is rapidly increasing. Among various off-site (OSC) construction methods, the front runner is the steel-based box-type modular construction method. Compared to the existing wet construction method, the steel modular construction method is increasing in terms of securing economic feasibility by shortening the construction period and increasing the prefabrication rate. However, due to the recent rise in raw materials and a sharp rise in the exchange rate, the economic feasibility of the wet method is deteriorating compared to the wet method. Therefore, a hybrid between 9-Matrix-based OSC construction methods is considered as a solution, away from the steel-box type combination, and a comparative study of the construction process between each construction method is being conducted. It was analyzed that the PC modular construction method shortened the construction period by 9% compared to the existing steel modular construction method. On the other hand, when comparing the construction period of the Gayang-dong demonstration complex calculated assuming that all modules are applied, it is estimated that there will be a 12% reduction in construction period compared to the steel modular method and a whopping 43% compared to the RC method.
