Interest in the use of semiconductor-based photocatalyst materials for the degradation of organic pollutants in a liquid phase has grown, due to their excellent performance and response to the light source. Herein, we fabricated a NiO-SiCTiO2 ternary structured photocatalyst which had reduced bandgap energy, with strong activation under UV-light irradiation. The synthesized samples were examined using XRD, SEM, EDX, TEM, DRS, EIS techniques and photocurrent measurement. The results confirmed that the two types of metal oxides were well bonded to the SiC fiber surface. The junction of the new photocatalyst exhibited a large number of photoexcited electrons and holes. The holes tended to oxidize the water and form a hydroxyl radical, which promoted the decomposition of methylene blue. The close contact between the 2D SiC fiber and metal oxide semiconductors expanded the scope of absorption wavelength, and enhanced the usability of the ternary photocatalyst for the degradation of methylene blue. Among three synthesized samples, the NiO-SiC-TiO2 showed the best photocatalytic effect, and was considered to have excellent photoelectron transfer due to the synergy effect between the metal oxide and SiC.

기업의 혁신적이고 적극적인 성향 또는 활동인 기업가 지향성은 최근 국제경영 분야에서 중요하 게 연구되고 있다. 특히, 기업가 지향성은 기업의 학습 및 역량 개발을 촉진하고, 새로운 시장의 기 회를 인지하고 포착하며, 경쟁 기업들과의 차별화를 가능하게 한다는 점에서 성과에 긍정적인 영향 을 미친다는 주장이 있다. 일부 연구에서는 기업가 지향성이 오히려 성과에 유의미한 영향을 미치 지 않는다는 연구결과도 나타났다. 하지만, 기업가 지향성과 성과 간의 관계는 기업의 자원 및 역 량 등 내부적 환경에 따라 상의할 가능성이 크다. 본 연구에서는 기업의 내부적 요인으로서 흡수 역량이 기업가 지향성의 실행에 영향을 미치는 주요 요인으로 작용할 수 있다는 점을 고려해서 흡 수 역량의 두 가지 차원(잠재적 흡수 역량, 실현적 흡수 역량)이 기업가 지향성-수출 성과에 미치 는 영향을 실증적으로 분석하고자 한다. 한국 수출 기업들을 대상으로 기업가 지향성, 흡수 역량, 수출 성과에 대한 설문 조사를 실시하였다. 분석 결과, 기업가 지향성은 수출 성과에 긍정적인 영 향을 미치며, 기업의 실현된 흡수 역량이 높을수록 기업가 지향성의 긍정적인 영향은 강화되는 것 으로 나타났다. 이에, 본 연구는 기업가 지향성-수출 성과 간의 관계에 영향을 미치는 기업의 내부 적 요인을 검증함으로써 학문적 및 실무적 관점에서 의미 있는 시사점을 제공할 수 있을 것으로 기 대된다.

Under the bilateral nuclear cooperation agreements (NCA) and its administrative arrangement (AA), Korea annually exchanges the inventory of subject items (including nuclear materials (NM), non-nuclear materials, equipment, and related information) with US, Canada and Australia. Also, the government performs export control procedures such as notification or prior consent during importing and exporting of relevant items. It makes NCA a means of realizing the nuclear non-proliferation regime. However, it raises difficulties in management because the entity that uses and treats those items are end-user, not the authorities of AA, the government agency of each country. Accordingly, to increase the accuracy and effectiveness of item management at the national level, it is required to establish a system for the individual company that has the NCA items, considering the characteristics of each company. In this study, significant companies are classified into more than three types, and the management system of the items subject to the agreement is analyzed. Each company’s item management status has different characteristics depending on its role (position) within the entire nuclear fuel cycle, the type of facility, its possessed items, the main form of national trade, and the frequency of domestic movement. Those differences lead to diversity in the management systems currently owned by each company. For example, from the perspective of nuclear materials, institutions requiring bulk management have systematically organized their management system and obligation code program compared to the ‘item institutions’ that can track batch history for all facility inventory changes. Although Domestic law imposes only the duty of origin management on NMs, fuel manufacturers or research institutes have established their standard obligation codes to manage multiple obligations. The non-nuclear materials and equipment can be easily tracked and controlled by individual items. However, the management of NCA items is a complicated task involving various processes, from importing goods to using, storing, managing inventory change, selling to others, or fulfilling the obligations of AA when exporting. In particular, when the movement of items within a company or international trade occurs frequently, or when the end-users are diverse, the management difficulties increase. So a system that can accurately convey and track items subject to the AA is needed. In addition, since various entities are related, it is necessary to improve understanding of NCA items to increase the system’s utilization and effectiveness. The comparison result and requirement for system improvement based on the review above will be reflected in the history management system for items subject to NCA under development.

The guidelines for cyber security regulations at domestic and foreign nuclear facilities, such as KINAC/RS-015, NRC’s RG5.71 and NEI 13-10, require the establishment of security measures to maintain the integrity of critical digital assets (CDAs) and protect them as threats to the supply process. According to the requirements, cyber security requirements shall be reflected in purchase requirements from the time of introduction of CDAs, and it shall also be verified whether cyber security security measures were properly applied before introduction. Domestic licensees apply measures to control the supply chain in the nuclear safety sector to cyber security policies. The safety sector supply chain control policy has areas that functionally overlap with the requirements of cyber security regulations, so regulatory guidelines in the safety sector can be applied. However, since most of the emergency preparedness and physical protection functions introduce digital commercial products, there is a limit to applying the control of the supply chain in the safety field as it is. It is necessary to apply supply chain control operator policies, procedures, and purchase requirements for each SSEP function, or to establish cyber security integrated supply chain control requirements. In this paper, based on the licensee’s current supply chain control policy, the cyber security regulation plan for supply chain control according to the SSEP (Safety-Security-Emergency Preparedness) function of CDAs is considered.
