  • As the size of container ships continues to increase, not many existing harbors can host the super-container ship due to its increased draft and the corresponding dredging requires huge budget. In addition, the minimization of waiting and loading/offloading time is the most important factor in harbor competitiveness. In this regard, mobile-harbor concept has been developed in Korea to achieve much improved harbor capacity and efficiency. In developing the concept, one of the most important elements is the operability of crane between two or more floating bodies in side-by-side arrangement. The container ship is to be stationed through a hawser connection to an outside-harbor fixed-pile station with the depth allowing its large draft. The mobile harbors with smart cranes are berthed to the sides of its hull for loading/offloading containers and transportation. For successful operation, the relative motions between the two or more floating bodies with hawser/fender connections have to be within allowable range. Therefore, the reliable prediction of the relative motions of the multiple floating bodies with realistic mooring system is essential to find the best hull particulars, hawser/mooring/fender arrangement, and crane/docking-station design. Time-domain multi-hull-mooring coupled dynamic analysis program is used to assess the hydrodynamic interactions among the multiple floating bodies and the global performance of the system. Both collinear and non-collinear wind-wave-current environments are applied to the system. It is found that the non-collinear case can equally be functional in dynamics view compared to the collinear case but undesirable phenomena associated with vessel responses and hawser tensions can also happen at certain conditions, so more care needs to be taken.

  • Objectives : This study attempts to identify the concept of Link meridian in previous medical books, and explore how Link meridian theory was used in a clinical practice focusing on YeTianshi. Methods : This study looked at the medical books related to acupuncture and moxibustion in the past and the part where Link meridian is mentioned in the annotations of "Huangdineijing" and "Nanjing", and examined how medical doctors prior to YeTianshi used Link meridian in a clinical practice. And then this study examined treatment cases in the medical records of YeTianshi. Results & conclusions : Yang-Link meridian and Eum-Link meridian were arranged as ascending route by the majority of medical doctors. However, there are doubts because startpoints of them are not "Jeyanghoe" and "Jeeumgyo" respectively described in "Nanjing". Link meridian is thought to be a structure that connects each meridian passing through crossing points with each crossing point itself as a starting point. Thus, Link meridian can be seen as a role in strengthening the connection of crossing meridians and balancing and controlling those meridians centering on each crossing point. The point that YeTianshi's identifying that pathology of Eight extra meridians associates with liver and kidney(肝腎) to be a symptom of weakness, and his development of Link meridian's physiology and pathology through the relationship with other Eight extra meridians are thought to be more advanced than the previous medicine prior to YeTianshi.

  • Background : There have been a variety of healthcare systems related to CAM practitioners developed in each country. However, the European cases have not been widely introduced in Korea so far. In the case of Germany, CAM practices have been developed in the frame of "Heilpraktiker" system. Objectives : The objectives of this study were to review the historical development and current situation of German Heilpraktiker system and its conflicting relationship with Western medical doctors, in order to utilize it as basic data for the conflict resolution between Western- and KM doctors in Korea. Methods : The historical development, current regulations and education system of Heilpraktiker were assessed. Research articles, reports, government publications and websites dealing with this issue were searched for and analyzed. Results : Heilpraktiker system was developed within German historical and cultural situation where naturopathic traditions were reilluminated in connection with modernization process of the state under the influence of romanticism formulating German nationalism. Between the concept of "Kurierverbot"(prohibition on medical treatment by non-physicians) and "Kurierfreiheit"(freedom of medical treatment), Heilpraktiker achieved a limited but legitimated right to conduct non-biomedical treatments from the state in the process of the formulation of modern German medical system. In this process, the conflicts between medical doctors and heilpraktikers have been also growing up to now. Conclusions : Heilpraktiker system, officially recognized with the legislation of Heilpraktiker law in 1939, stands at a crossroads between the continual development through strengthening its professionality, and abolition of the system due to its lack of quality control and medical evidence mostly argued by Western medical doctors, which has considerable implications for Korean situations in terms of the conflicting relationship between KM- and Western medical doctors. In this regard, it is necessary to discuss the debates on the concept "Kurierfreiheit"(freedom of medical treatment) developed within German tradition of medical pluralism.

  • 본 연구는 어린이집 흥미 영역 환경과 유아가 어떻게 접속되고 배치되는지, 그 과정을 탐구하였다. 유아는 환경이라는 물질과 얽혀 세상을 알아간다. 알아가는 그 과정에 주목하여 흥미 영역이라는 익숙한 환경이 유아의 행위에 어떤 영향을 주는가를 살피기 위하여 물질과 인간 사이의 힘을 강조한 들뢰즈의 접속-배치 개념으로 이해해보고자 하였다. 이를 위해 서울특별시 B 어린이집 만4-5세 혼합반 유아 20명을 2023년 3월부터 5월까지 사전 관찰 2회, 연구관찰 5회를 총 2시간씩 참여 관찰하였다. 연구 결과 첫 번째, 유아의 진짜 흥미는 성인의 시선이 아닌 유아의 시선에서 찾을 수 있었다. 두 번째, 흥미 영역 환경의 공간과 놀이 자료는 놀이 유형이라는 질서에 맞춰 구조적으로 배치되어 있지만 유아와 접속되면서 그 경계가 모호해졌다. 세 번째, 유아의 놀이가 각 흥미 영역을 벗어나지 않고 놀이하는 것처럼 보였지만 공간은 그 자체로 흥미가 발현되는 하나의 덩어리였다. 본 연구로 인하여 흥미 영역 환경구성에 대한 교수자의 실천에 도움이 되고, 공간과 매체라는 환경이 유아와 접속-배치되면서 유아의 사고에 어떤 흔적을 남기게 될까 매 순간 물음을 던지는 교수자가 되길 기대한다.

  • 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.

  • The Virtual organization is a alternative organization for redesigning the classical organization. With the advantages of the quickness of decision making and also connection with other organization, it can be well prepared for the consumer's need. With recent increased interest in virtual organization, there are many companies that consider the virtual organization as practical use. However, it is still in an early stage of the research and the concept has not been established for the virtual organization. The purpose of this research is to systematize the understanding of the virtual organization for the future organizational model. The differences of existing organizational structure can be compared with these three reasons of practical use for the virtual organization, the development of information technology, the importance of strategic choice and unreliable environment. Also, the framework for the virtual organization can be presented with its profiles. The use of this research can be appeared by analyzing the given framework from the companies that are already made practical application of the virtual organization. For the future, this research will give the direction and its viewpoint how this will be used for achieving the competitive advantage of companies and practical use for actual aspects with the pursuit of this research.
