해상화학사고가 증가함에 따라, 해상에 유출된 화학물질로 인한 피해가 커지기 때문에 해상화학사고 대응요원의 양성이 요구되고 있다. 본 연구에서는 해상화학사고 대응 전문요원 양성을 위한 국내외의 교육훈련 내용을 살펴보고, 국내 HNS사고 대응 교육훈련교재 개발에 활용하기 위하여 교육훈련 내용에 대한 비교분석을 실시하였다.

매년 해양사고를 줄이고자 선원들에게 정기적인 안전교육이 제공된다. 그러나 물리적인 교육 공간의 한계로 일부 피교육자는 피교육자가 원하는 시점에 안전교육을 받지 못하는 문제가 발생한다. 최근 기존 교육방식의 문제점을 극복할 수 있는 기술로 VR 기술이 주목받고 있다. 몰입감의 향상을 위하여 가상환경과 사용자의 상호작용의 제공이 가능하고, 비대면 교육을 수행할 수 있기 때문이다. 본 논문에서는 야간 등화식별 교육, 소형 및 중형 화제 교육, 컨테이너 퇴선 교육으로 구성된 VR 기반 선원 안전교육용 콘텐츠 개발을 수행하였다. 또한, 교육 효과를 정량적 평가하기 위하여 각 교육 콘텐츠의 체험 후 몰입감, 용이성, 기존 교육방식과의 비교 그리고 VR 교육 콘텐츠의 만족도에 대한 설문조사를 수행하였다. 설문조사 결과 몰입감은 53.83%의 긍정 평가를 받을 수 있었으며, 용이성은 65.38%의 긍정 평가를 받을 수 있었다. 그리고 기존 교육방식과의 비교 항목은 69.23%의 긍정 평가를 받을 수 있었다. 마지막으로 VR 교육 콘텐츠의 만족도 항목은 항목에선 약 46%의 긍정 평가를 얻었으며, 중립은 34%의 결과를 얻을 수 있었다.

Purpose: This study aims to overcome the problem of private education market environment which is polarized into commercialized large private education institutions and small and medium sized private education institutions in a poor business environment, and develop systematic performance measurement model applicable for small and medium sized private education institutions. Methods: To develop the BSC which measures financial and non-financial indicator in a balanced manner and introduce the BSC into private education institutions that contain conflicting goals "EDUCATION" and "PROFIT". In particular, Utilizing the methodology of AHP, the priority of strategies and execution assignments are derived. Results: BSC model was developed and introduced by cooperating with executives of the private education institution. Moreover, the study permits to achieve the strategy, enterprise-wide vision and mission by deriving strategy map and applying it to the private education institution. To measure the performance of BSC model instruction, KPI corresponding to the strategic objectives of each perspective was derived. Conclusion: BSC model generally introduces to large-sized companies and public institutions. In this study, BSC model is developed by focusing on small and medium sized private institution. Furthermore, this study is more than simple model development, it makes a connection with achievement of strategic objectives, enterprise-wide vision and mission through strategy map and strategy execution method. Through the developed BSC model and strategy execution method, utilization plan in practice and customized model for private education institutions coexisting profit and non-profit objectives were developed, and academic implications were presented.

Diet composition and trophic level of Trachurus japonicus were studied using 417 specimens collected by trawls, set nets and purse seine fisheries from March 2019 to February 2020 in the South Sea of Korea. The size of T. Japonicus ranged from 7.0 to 49.8 cm in total length. T. japonicus were a carnivore that fed mainly on euphausiids and pisces. In eddition, T. japonicus fed on small quantities of cephalopods, crabs etc. T. japonicus showed ontogenetic changes in feeding habits. The proportion of euphausiids decreased inversely proportional to body size whereas the consumption of pisces gradually increased. As body size of T. japonicus increased the mean number of prey per stomach and the mean weight of prey per stomach tended to increase, but the mean number of prey per stomach was not significantly different. As a result of the feeding strategy analysis, T. japonicus were specialized feeders with pisces and euphausiids as their dominant prey. The trophic level ranged between 3.57 ± 0.54 and 3.91 ± 0.65, and increased asymptotically with size of specimens. The average trophic level of the T. japonicus was 3.79 ± 0.61.

승조원의 안전 교육은 생명과 직결되므로 필수적으로 수반되어야 하는 교육이다. 선박 비상 대응 교육은 좌식 교육 보다 실습 교육으로 제공했을 때, 피교육자의 만족도 및 교육 효과가 높게 나타난다. 하지만, 선박 비상 대응 교육은 실습으로 진행하기에는 현실적으로 시간 및 장소 등의 교육 여건이 부족하다. 최근들어 교육에 있어 VR을 사용하는 기술이 각광을 받고 있다. 가상 현실을 통한 실습은 시간 및 장소의 여건에 구애받지 않고, 교육 효과를 높일 수 있으므로 타 교육 기관에서도 지향하고 있는 교육 방법이다. 한편, VR 기반의 교육을 하기 위해서는 관련 기술 개발과 컨텐츠 개발이 필수적으로 수행되어야 한다. 본 연구에서는 VR 기반의 컨텐츠 개발을 수행하였다. 개발 시나리오는 항행과 사고 대응 방안에 대한 내용이며, 좁은 수로와 제한 시계에서의 항행에 대해 개발하였다.

The aim of this study is to research attributes of fishermen's occupational accidents for investigating the measure of risk control on situational condition in the Korean offshore and coastal fishing vessel. Using data of fishermen's occupational accidents are from National federation of fisheries cooperatives for 2013. The results were as belows; Occupational accident occurrence rate was 29.5‰, slips & trips and struck by object and contact with gear were shown severe occurrence pattern. Occupational accident occurrence rate of offshore fisheries was 130.2‰, coastal was 16.9‰, specially the risk rates were severely high in several type of danish seine, stow net and offshore trap. Death rate by accidents was 10.6‰ and by fall into the water in occurrence pattern was 5.5‰.

The aim of this study was to determine the physiological response and the applicable concentration ranges of anesthetic clove oil and anesthetic lidocaine-HCl, and to investigate the synergistic effect of a mixture of these two anesthetics on the in grass puffer (Takifugu niphobles). The anesthesia times decreased and the recovery times increased with increasing concentrations of clove oil and lidocaine-HCl. Applicable concentration ranges for long-term transportation requiring more than 1 hour were 2 ppm for clove oil and 50 ppm for lidocaine-HCl. With mixtures of the two anesthetics, the anesthesia time decreased as the admixture concentration of clove oil and lidocaine-HCl increased. Anesthesia times of experimental groups with the combined anesthetics were shorter than those with the same concentrations of clove oil or lidocaine-HCl alone. Plasma cortisol concentrations were highest at 6 hours in all experimental groups anesthetized with the mixture of clove oil and lidocaine-HCl, while all groups with clove oil or lidocaine-HCl alone had the highest plasma cortisol concentrations at 12 hours. Plasma glucose concentrations were highest at 12 hours in experimental groups anesthetized with the mixture of clove oil and lidocaine-HCl, while groups with clove oil or lidocaine-HCl alone had the highest plasma glucose at 24 hours. The results of this study provide basic information about anesthetics and the synergistic effect of mixtures of anesthetics in this fish species. This information should be useful for aquaculturists who require methods for safe and easy fish handling, and for transporters who require that minimal stress is imposed on fish during transport.

The head-on collision of two solitary waves are examined using a boundary element method. Attachment, detachment times and alplitudes and maximum run-up times and amplitudes are computed. Consolidation times show local minimum value if two waves are of equal amplitudes are colliding. Attachment times show local maximum value if the amplitudes of two waves are the same. The detachment time show local maximum if two wves are the same. The detachment amplitude show local minimum values if the amplitude e(=a/h) is greater than 0.3.
