본 연구는 혁신 생태계 조성을 통한 경제성장 뿐만 아니라 자기고용을 통한 실업해소, 성장 단계별 적절한 인재 채용을 통한 고용창출 등 작금에 우리가 직 면한 사회·경제적 문제를 해결하기 위한 수단으로 창업이 매력적인 대안이 될 수 있음을 전제하였다. 나아가, 이와 같은 전제를 바탕으로 실질창업 활성화에서 중요한 것은 기회인식임을 제안하였고 기회인식에 영향을 미치는 변수들을 규명 하였다. 구체적으로, 기업가정신이 기회발견행동 및 창업기회인식에 미치는 영향 과 기회발견행동이 창업기회인식에 미치는 영향을 구조방정식 모델을 통해 실증 하였다. 또한 기업가정신과 창업기회인식의 관계에서 기회발견행동의 매개효과를 실증하였다. 연구결과 첫째, 기업가정신은 창업기회인식은 물론 기회발견행동을 구성하는 4개의 하위변수에 모두 통계적으로 매우 유의미한 영향을 미치는 것으 로 나타났다. 둘째, 기회발견행동의 하위 변수 중 관찰과 아이디어 네트워킹은 창업기회인식에 통계적으로 유의미한 영향을 미치는 것으로 나타났다. 셋째, 기 업가정신이 창업기회인식에 미치는 영향에서 아이디어 네트워킹의 매개효과가 검증되었다. 본 연구는 이상의 실증분석 결과를 바탕으로 기업가정신 및 창업교 육 혁신을 중심으로 이론적·실무적 시사점을 제안하였음에 의의가 있다.

This study is for evaluation and optimization of workers’ radiation exposure for dismantling Reactor Vessel (RV) at Kori unit 1 in connection with its decommissioning process for the purpose of establishing Radiation Safety Management Plan. This is because the safety of workers in a radiation environment is an important issue. The basis of radiological conditions of this evaluation is supposed to be those of 10 years after the permanent shutdown of Kori unit 1 when dismantling work of Reactor Vessel would suppose to be started. Dose rates of work areas were evaluated on the basis of spatial dose rate derived from activation level calculated by MCNP (Monte Carlo N-Particle Transport) and ORIGEN-S code. RV are radiated by neutrons during operation, creating an environment in which it is difficult for operators to access and work. Therefore, the RV must be dismantled remotely. However, due to work such as installing devices or dismantling surrounding structures, it is not possible to completely block the access of workers. Accordingly, the exposure of workers to the RV dismantling process should be assessed and safety management carried out. The dismantling process of Kori unit 1 RV was developed based on in-situ execution in atmospheric environment using the oxigen-propane cutting technology as the following steps of Preparation, Dismantling of Peripheral Structures, Dismantling of RV and Finishing Work. For evaluation of exposure of RV dismantling work, those processes of each steps are correlated with spatial dose rates of each work areas where the jobs being done. Results of the evaluation show that workers’ collective dose for RV dismantling work would be in the range of 536–778 man- mSv. The most critical process would be dismantling of upper connecting parts of RV with 170–256 manmSv while among the working groups, the expert group performing dismantling of ICI (In-core instrumentation) nozzles and handling & packaging of cut-off pieces is evaluated as the most significantly affected group with 37.5–39.4 man- mSv. Based on the evaluation, improvement plan for better working conditions of the most critical process and the most affected workers in terms of radiation safety were suggested.
