  • In this study, the effects of embedded optical fibers on the static properties under tensile load and dynamic properties under fatigue load of composite laminates were investigated by experimental tests and finite element analysis. Based on the results, it can be concluded that the embedded optical fiber sensors do not have significant effects on the structural integrity of the smart composite structures except when the sensors are embedded perpendicular to the adjacent reinforcing fibers under fatigue loading. An intensity-based optical fiber sensor was embedded in the crossply composite laminates to monitor the fatigue damage by detecting the stiffness changes of the laminates. The result of this experiment has shown that the intensity-based optical fiber sensor has large potential to monitor the fatigue damage of composite structures by detecting the stiffness changes of the structures with simple and inexpensive instruments and without complex post-processing of measured signals. In addition, the optical fiber sensor showed good resistance to fatigue loading and wide sensing ranges of stiffness.

  • With the change of patterns and the environment of the national standard of living the prohlem of environmental pollution became increasingly serious. Because of the enormous increase of various kinds of used and (after utilization) useless articles, efforts to save resources as well as the environment and the promotion of reprated utilization and recycling are inavoidable. The recognition of an environmental an health problem, and the desire for nonpollution created a desire for environment-friendly products in order to avoid an environmental consumptionism. Drink vending machines making use of vessels only once are closely related to the environmental problem. It is therefore necessary to develop an ecologically designed vending machine. In this study the backgrounds and concepts of green design, classification, construction and the environment of a drink vending machine arc analyzed. From this st1.rting-point a concept for the design of a drink vending machine is developed by two concepts : Type A (seperated-gathering type) and Type B (recycling type). Then three defferent types of vending-machines arc introduced a wall -adherable type, a center est1.blishable type and a desk top type. The conclusion of the text is threefold. There are needs for an ecological design of vending machines, ergonomIc considerations and a harmonization of the styldapperarance) of the machine and its circumferences.

  • FRP(Fiber glass reinforced plastics) is compound with materials, which are created to combine each other materials, of which nature of mechanical and chemical are different. Even though the weight and the thickness are identic, its physical figure of characteristic changes with consisting of lay-up and work situation. It is also a method of creating after manufacturing of mould. It has feature that manufacturing of FRP runs parallel design of material with design of structure simultaneously. The rule of FRP structure is distinguished from the length of a ship and it is hard to catch the feature of structure mechanics due to identical formula and figure used for it regardless of the shape of a ship or the speed. This studying, basing on a small FRP ship, will show te fundamental data needed to design of structure analysing the feature of intensity with direction, the method of Lay-up, and the characteristic of materials of FRP.

  • This study aims to evaluate the industrial cluster policy implemented in Korea during the last decade or so, examine whether it can still be a valid policy measure in the creative economy regime, and propose policy directions for the future. It is evaluated that the cluster policy has contributed to increasing productivity by improving networks between companies, universities and research centers and thus strengthening innovation infrastructure. The policy, however, by its characteristics of government-domination, failed to develop open-ended and flexible spontaneous clusters. Industrial clusters have the capability to contribute to the virtuous circle of creative economy by enhancing creativity and innovativeness, and subsequently by increasing value-added. In order to maximize these positive effects, a few suggestions are made, including being faithful to the very nature of clusters, e.g. geographical proximity and connectedness, intending clusters with creativity well maintained, orienting toward multi-scalar clusters with a mixture of local and global perspectives, and matching regional and industrial policies with regards to clusters.

  • 최근의 하천복원사업은 인위적으로 축소 또는 소실된 하천공간을 지형학적으로 되돌리기 위한 방향과 강이 가진 자연의 역동성의 복원에 주안점을 두고 있다. 최근 국내에서도 하천공간 확보라는 측면에서 구하천 구역을 복원하려는 시도가 이뤄지고 있고 대표적으로 청미천, 함평천, 황구지천 등에서 기존의 제방을 후퇴시키고 과거의 하천공간을 하천으로 되돌려 주었다. 그러나 이러한 시도는 구하도 또는 폐천부지 복원사업의 일환으로 시행되었으며, 복원된 공간규모가 크지 않아 사업의 효과를 크게 장담할 수 없는 현실적인 한계가 있다. 따라서 홍수에 안전하며 자연과 인간이 공존하는 터전으로의 공간복원, 그에 따른 하천생태계의 보전과 복원, 레저와 레크레이션이 가능한 친수공간 조성 등 하천기능의 강화와 융합을 종합적으로 고려한 다차원 하천공간 복원계획과 설계의 절차가 필요하다. 이를 위해서는 먼저 유역기반의 문제점과 그 원인에 대한 인식이 선행되어야 하고 그 해법으로 하천공간 확대의 필요성이 도출되어야 한다. 이후, 하천공간 복원 및 활용과 관련된 기본방향이 설정되며 세부 복원목표가 설정되어야 한다. 복원목적과 목표가 세워진 후, 복원대상지를 선정하고 공간 활용방안이 제시되면, 목표달성 여부 판단을 위한 효과분석이 필요하다. 만약, 기대효과를 달성할 수 없을 것으로 예상된다면 복원목표 재설정 및 복원대상지의 재선정이 필요할 것이다. 이와같이 하천공간 복원사업을 시행함에 있어 간결하고 단계적으로 접근하기 위해 본 연구에서는 다차원 하천공간 복원프레임워크를 개발하여 제시하였다. 제안된 하천공간 복원프레임워크를 통해 하천공간복원으로 인해 영향을 미칠 수 있고 또한 영향을 받을 수 있는 물리, 생물, 사회, 경제 등의 다양한 분야의 구조를 통합한 하나의 방법을 제시함으로서 임시방편 수준의 파괴된 하천복원사업에 변화를 주고 프레임워크를 통해 하천공간복원에 대한 응집력 있는 접근법을 적용하도록 촉진하여 복원사업에 참여하는 사람들 간에 공통의 유대감을 형성하는데 도움이 되고자 한다.

  • With the rapid aging of the nation's population and the increasing number of elderly people with difficulties in daily life, the elderly care system was implemented for social solidarity. Structural problems in the long-term care system that emerged after the introduction of the system are demanded, and the problem of functional readjustment between nursing hospitals and facilities is raised due to the lack of continuity of care for the elderly by institutional and salary types. In this study, we set up research problems related to personnel, staff, and services to address the problem and conducted FGI. Research has shown that the number of elderly and recognized people in the region, the number of elderly and elderly patients, needs to be reflected in long-term care demand, the direction of appropriate institutional and manpower supply policies, and the establishment of local government goals and plans to strengthen the long-care institutions. It was revealed that non-medical accident arbitration bodies are needed to apply the cost of food insurance, provide programs through links with relevant institutions, and manage the admission smoothly.

  • Common issues in research and policy on cultural heritage can be extracted among Eurasian countries although countries in the region show different colors of policies and studies. Among them one thing peculiar to Central Asian countries is that in general they do not have well delineated laws and regulations on the protection of cultural heritage. It may be because they had no enough time and experience to legislate and implement relevant laws and regulations ever since they got independence. Research on cultural heritage in Central Asian countries is often made in cooperation with foreign institutions. As shown in archaeological excavation projects in Central Asian countries, cooperative projects exceed noncooperative ones in terms of size and longevity. UNESCO, through its projects on the Serial and Transboundary World Heritage Nomination of the Silk Roads in Central Asia, also supports countries in Central Asia and others along the Silk Road in order to facilitate inclusion of their cultural heritages in the Tentative List of the World Heritage. With regard to activities on the protection of cultural heritage, while respective countries in Central Asia have made good efforts, they could not produce effective outcomes due to short of budget and specialized manpower. They have rich resources of cultural and documentary heritage but their registered heritages on the UNESCO's World Heritage List and Memory of the World are under-represented because of short of technology and experience among other things. A new trend in cultural heritage studies that combined cultural heritage with tourism has merged in recent years. While some critics have raised some negative questions, this new fashion became popular and will continue with the support of governments of Silk Road countries. In conclusion, Korean institutions are further encouraged to organize cooperative networks for research and policy with respective Eurasian countries.

  • Archaeological Heritage is material testimony of national and regional history, and it is one of the tourist's attractions. So it has very important meaning and identical value for a local residents. Public concern on the heritage site elevate higher day by day. They are willing to use it for a multiful purpose, cultural, educational, and even commercial one. But Archaeological Heritage is fragile, and visitors can impact negatively for protection and management of the authenticity on the heritage site. In this research I try to compare legal and administrative measure for the protection, management, and culturalization of Archaeological Heritage in many countries. And I suppose sustainable and practical strategies for keeping integrity of heritage.
