Public officials are volunteers for the people, and the police are in charge of the safety of the people. In particular, the marine safety of Korea, which has three sides of the sea, is very important. The education of maritime police is a very important factor due to the specificity and risk of the sea. In particular, since the new curriculum is linked to the job while in office, factors related to educational performance are more important. In this study, the relationship between personality characteristics and academic burnout was examined for 200 new maritime police officials. Among the five factors of personality characteristics, extroversion factors, neurotic factors, and emotional exhaustion factors were extroversion factors, neurotic factors, and cynicism factors, and extroversion factors, neurotic factors, and integrity factors. In particular, the five factors of personality characteristics that have the greatest influence on academic burnout were neurotic. For the educational satisfaction and effectiveness of the new maritime police officer, it is necessary to minimize the psychological margin and stress of the new maritime police officer.

ESG (environmental, social, governance) management is being introduced with the goal of sustainable development of the company in risk management, which identifies and judgement various risks that may occur in the industry. In the future, ESG evaluation will be used more as a value judgment tools for corporate sustainability. This ESG evaluation was used to manage the company's accident prevention level. Through morphological analysis of the current ESG evaluation system, it was found that the quantitative 'safety evaluation index' available in ESG was insufficient through analysis of safety evaluation items. In this study, domestic and foreign industrial accident data was analyzed, 'accident contributing factors' that required intensive management were derived, and major safety management items that needed supplementation were selected based on the results. ESG safety evaluation indicators were developed through the process of optimizing the selected items into evaluation factors suitable for 'accident prevention management'.

'양손잡이 조직(Organizational Ambidexterity)'은 새로운 기회를 찾고 위험을 감수하며, 신제품이나 신사업을 개발해 가는 탐색(Exploration) 역량과, 최소한의 리스크와 보유한 자원을 토대로 기존 제품이나 서비스를 중심으로 효율성을 높이는 활용(Exploitation)적 혁신을 동시에 추구하는 조직의 능력으로 경영자들이 비즈니스 환경의 난기류와 다차원성에 대처하도록 권고하는 개념들 중 하나이다. 본 연구는 스타트업의 양손잡이 역량 균형이 기업 성과에 미치는 영향에 대한 연구를 기반으로 양손잡이 역량이 실제 스타트업에 긍정적으로 영향을 미치는 지를 조사하는데 목적으로 하고 있다. 따라서 탐색(Exploration)과 활용(Exploitation)의 적절한 균형(Balance)을 중심으로 기업성과에 미치는 영향과 더불어 환경적 동태성(Environmental Dynamics)의 조절효과에 대하여 알아보고 분석하였다. 실제로 선행 연구를 통해 탐색(Exploration)과 활용(Exploitation)에 모두 관여하는 양손잡이 기업들이 하나에 집중하는 기업보다 우수한 성과를 달성할 가능성이 높은 것으로 나타났으며, 탐색(Exploration)과 활용(Exploitation)의 적절한 균형(Balance)을 유지하는 것이 생존과 번영을 위해 중요한 것으로 나타났다. 특히, 자원이 부족한 스타트업의 경우 부족한 자원을 효과적으로 활용하고 양방향으로 행동할 수 있는 능력은 경영 능력과 역량에 달려 있기 때문에 지속적인 생존을 위해 탐색과 활용의 균형을 맞추고 효과적인 조직을 구축해 양손잡이 조직으로 거듭나야만 한다. 양손잡이 조직에 대한 연구 이론은 보통 여유 자원이 높은 대기업을 기준으로 정의되고 있으며, 상대적으로 여유 자원의 수준이 낮은 중소기업이나 스타트업을 위한 양손잡이 조직의 의미와 이러한 기업들이 추구할 수 있는 현실적인 실행방안에 대해서는 연구가 부족한 실정이다. 따라서, 본 연구는 실제 스타트업 기업의 성장을 위한 전략적 방향 설정을 제시할 수 있으며, 급격하게 변화하는 시장에서 스타트업의 양손잡이 역량과 기업성과 영향 관계를 분석하여 학술적인 기여를 할 수 있을 것으로 기대한다.

Various efforts are needed to prevent accidents because ship collisions can cause various negative situations such as economic losses and casualties. Therefore, research to prevent accidents is being actively conducted, and in this study, new leading indicators for preventing ship collision accidents is proposed. In previous studies, the risk of collision was expressed in consideration of the distance between ships in a specific sea area, but there is a disadvantage that a new model needs to be developed to apply this to other sea areas. In this study, the density-based ship domain DESD (Density-based Empirical Ship Domain) including the environment and operating characteristics of the sea area was defined using AIS (Automatic Identification System) data, which is ship operation information. Deep clustering is applied to two-dimensional DESDs created for each sea area to cluster the seas with similar operating environments. Through the analysis of the relationship between clustered sea areas and ship collision accidents, it was statistically tested that the occurrence of accidents varies by characteristic of each sea area, and it was proved that DESD can be used as a leading indicator of accidents.

Competition in the broadcasting market is intensifying as OTT services are spreading. And Korea is positioned as a competent international contents supply base. This can be helpful for the domestic contents production industry. However, it can result in being incorporated as a subcontractor in the global video industry. Therefore, it is necessary for Korean OTT operators to expand their market upto overseas and maintain competitiveness by linking content competitiveness to the sales expansion. This study was conducted to reduce the risk and encourage implementation through feasibility analysis of overseas business of domestic OTT operators. The North American market was selected as a region with high potential through in-depth interviews with experts and literatures review. And it was confirmed that the partnership with local platform is effective. Then, the sales and input costs were estimated, and business was evaluated using the net present value method. Totally 18 scenarios were created using multiple estimates for copyright cost, subscribers, and rate, which are highly uncertain. From the analyses, 8 scenarios were found to be acceptable. And copyright cost has the greatest impact on business success, followed by rates and subscribers.

연구목적: 본 연구는 요양병원 등 재난취약시설에 재난이 발생할 경우 잔류한 요구조자를 정확하게 파악하여 소방 등 대응기관에 제공하는 APC(Auto People Counting)의 인식률 개선에 목적이 있다. 현재 재난 발생 시 건물 내 요구조자의 현황 파악을 위해 대응기관이 재난 현장에 도착하여 건물관계자에게 직접 물어보고 있다. 이는 요구조자에 대한 부정확한 정보일 가능성이 있어 대응기관의 업무범위가 확대되고 이로인해 구조자의 안전에도 위험이 될 수 있다. APC는 건물내 출입하는 인원을 자동으로 집계하여 실시간 잔류인원 정보를 제공함으로써 재난 시 요구조자 현황을 정확히 파악할 수 있다. 본 연구에서는 APC가 보다 정확하게 출입 인원을 집계할 수 있도록 최적의 인공지능 알고리즘을 선정하는데 목적이 있다. 연구방법: 본 연구에서는 실제 재난취약시설에 설치되어 운영 중인 APC를 대상으로 카메라를 통해 출입 인원의 이미지를 인식하는 알고리즘을 개선하기 위해 CNN모델을 활용하여 베이스라인 모델링을 하였다. 다양한 알고리즘의 성능을 분석하여 상위 7개의 후보군을 선정하고 전이학습 모델을 활용하여 성능이 가장 우수한 최적의 알고리즘을 선정하는 방법으로 연구를 수행하였다. 연구결과: 실험결과 시간과 성능이 가장 좋은 Densenet201, Resnet152v2 모델의 정밀도와 재현율을 확인한 결과 모든 라벨에 대해서 정확도 100%를 나타내는 것을 확인할 수 있었다. 이 중 Densenet201 모델이 더 높은 성능을 보여주었다. 결론: 다양한 인공지능 알고리즘 중 APC에 적용할 수 있는 최적의 알고리즘을 선정하였고 이는 APC의 인식률을 개선하여 재난시 요구조자의 정보를 정확하게 파악하여 신속하고 안전한 구조작업이 가능할 것이다. 이는 요구조자의 안전한 구조뿐만 아니라 구조작업을 수행하는 구조자의 안전을 확보하는 데 기여할 것으로 기대된다. 향후 연무 등 다양한 재난상황에서 재난취약시설 내 출입인원을 정확하게 파악할 수 있도록 알고리즘 분석 및 학습에 대한 추가 연구가 요구된다.

In this study, the AHP (analytic hierarchy process) technique was used to analyze the risk of expected risk factors and fishing possibilities during gillnet fishing within the floating offshore wind farms (floating OWF). For this purpose, the risks that may occur during gillnet fishing within the floating offshore wind farms were defined as collisions, entanglements, and snags. In addition, the risk factors that cause these risks were classified into three upper risk factors and ten sub risk factors, and the three alternatives to gillnet fishing available within the floating OWF were classified and a hierarchy was established. Lastly, a survey was conducted targeting fisheries and marine experts and the response results were analyzed. As a result of the analysis, among the top risk factors, the risk was the greatest when laying fishing gear. The risk of the sub factors for each upper risk was found to be the highest at the berthing (mooring), the final hauling of fishing net, and the laying of the bottom layer net. Based on the alternatives, the average of the integrated risk rankings showed that allowing full navigation/fisheries had the highest risk. As a result of the final ranking analysis of the integrated risk, the overall ranking of allowing navigation/fisheries in areas where bottom layer nets were laid was ranked the first when moving vessels within the floating OWF was analyzed as the lowest integrated risk ranking of the 30th at the ban on navigation/fisheries. Through this, navigation was analyzed to be possible while it was analyzed that the possibility of gillnet fishing within the floating OWF was not high.

Civil aircraft must have captain and first officer. In general, the captain fulfills his role and responsibility for preventing danger during aircraft operation, and the first officer is in charge of assisting the captain. Historicclay, as 70% to 80% of aircraft accidents have been caused by pilot human factors, crew resource management (CRM)has been introduced and operated worldwide. On the other hand, safety behavior is a human behavior to protect from danger using knowledge and skills, and the captain and the first officer who perform operations in the aircraft's cockpit are expected to have different levels of safety behavior according to differences in competence, responsibility, and experience. Preceding studies have shown that pilots' safety behavior is influenced by non-technical factors such as CRM Skills rather than technical ability, and this study was conducted to identify differences in CRM competencies between captain and first officer and to verify whether the differences are correlated with safety behavior.
