본 논문에서는 GMDSS 시행이후 우리나라 선박들의 해난사고는 점차적으로 다소 줄어가고 있으나, 자체해난사고는 오히려 증가하고 있는데 그 원인은 GMDSS제도에 의하여 관리되지 않는 비 협약 소형선박들의 사고는 오히려 증가하고 있다. 해난사고가 가장 많이 발생하는 5톤미만의 소형선박들을 위한 현실적이고 합리적인 해양종합 통신시스템을 구축하고자 하는데 연구에 목적이 있다.

Objectives: The purpose of this study was to report the effect of complex Korean medicine treatments on Essential Tremor Plus (ET plus) patient aggravated by a traffic accident. Methods: We treated an ET plus patient with complex Korean medicine. The patient's resting tremor and kinetic tremor in both hands intensified after experiencing a traffic accident, with tremor in the left hand being worse than that in the right hand. Effect of complex Korean medicine treatment was evaluated using Fahn-Tolosa-Marin Tremor Rating Scale (FTMTRS), Numerical Rating Scale (NRS), and Beck Anxiety Inventory (BAI). Results: After 26 weeks of treatments (acupuncture, pharmacupuncture, cupping, Iigyeungbyunqi-therapy, and herbal medicine), the FTMTRS decreased from 38 to 15. NRS of Lt. upper limb pain decreased from NRS 9 to 0. BAI score also decreased from 31 to 17. Conclusions: Complex Korean medicine could be used to treat patients with ET plus aggravated by a traffic accident.

In Korea for 20 years(1993-2012), total number and average annual number of oil spills were 6,608 cases and total volume and average annual volume of oils spilt were $57,328k{\ell}$ and nearly $2,866k{\ell}/year$, respectively. The annual number of oil spills and annual amount of oil spilt tended to decrease with the lapse of year in Korea. As oil transportation worldwide continues to increase, many communities are at risk of oil spill disasters and must anticipate and prepare for them. Factors that influence oil spill consequences are myriad and rage from the biophysical to the social. In this paper, we analysed the emergency response systems and recovery apparatuses for oil spill accident in marine and proposed a developed oil diffusion apparatus which can be used to initial response stage by crew, and to extend golden times. This system can be minimized casualties for rescued people in disaster.

세계적 선박 배출가스 저감에 대한 규제로 인해 항만 및 부두에서 육상전원공급장치(AMP, Alternative Marine Power)가 지속적으로 사용되고 있다. 국내 또한 항만 대기질 개선 특별법에 따라 AMP의 사용이 의무화되고 있고, 다양한 친환경선박과 연계하여 활용하도록 지속적인 시도를 하고 있다. 본 논문에서는 AMP를 통해 선내 전력을 공급하는 상황을 모델링 하여 AC Load Flow Analysis를 수행하였다. 이를 통해 선박에 전력이 공급될 때의 전기적 파라미터와 손실 등에 대해서 분석할 수 있다. 아울러 Transient Stability Analysis를 통해 계통의 사고 발생 시 선내 발전기를 통한 무정전전환에 대한 HSGT(High Speed Generation Transfer)의 한계값을 도출하고 이를 적용하였을 경우 결과에 대해 검토하였다.

As per the rapid development of world economics the marine traffic volume was increased accordingly and caused frequent disasters in human lives and natural environment in the consequence of accidents. As the result of the above they started to establish Vessel Traffic System(VTS) and separation scheme in waterway from 1960' to prevent the marin traffic accident but the problem of safety at sea appears now as neither fully defined nor sufficiently analysed. At the present, the dominant factor in establishing the strategy of marine traffic has been safety of navigation concerning only with the ship, but the risk of society derives almost wholly from the nature of cargo. To measure the degree of danger for each ship there is suggested concept of safety factor numbers denoting the level of latent danger in connection with ship and her cargo. In this paper, where the strategy of VTS is put on controlling density of safety factor for control area. it suggested algorithms how to assign the vessels and also to get optimal sequence of vessels located to a sector in the sense of minimizing the passage delay. For the formulation of problem, min max and 0-1 programming methods are applied and developed heuristic algorithm is presented with numerical example to improve the efficiency of calculation.
