This paper is focused on the desirable improvement schemes of the local network of information and telecommunication network. In this study, we examined whether polices of information and telecommunication of government have been carried out a desirable programme to meet the public interest, found out several problems in the these policies. Such problems as follows : (1) a system of local information & telecommunication is developing by a Model of Top-Down. In the present management system, an interest of the public of local society about the local telecommunication network is a much lower level, (2) there is no general controlling roll of the local information & telecommunication, (3) there is no service controlling system of local telecommuni-cation, and (4) there is no organic coordinating system of inter-departments in the central government level. In order to resolve these problems, this study suggests a few desirable sxhemes for the local telecommunication : (1) an establishment of middle-long range planning for the integrated future network of info-telecommunication, (2) an organizing of telecommunication network being suitable for the local characteristics toward B-ISDN.

Under the long-term effect of corrosive environment, many cold-formed steel (CFS) structures have serious corrosion problems. Corrosion leads to the change of surface morphology and the loss of section thickness, which results in the change of instability mode and failure mechanism of CFS structure. This paper mainly investigates the elastic local buckling behavior of corroded CFS columns. The surface morphology scanning test was carried out for eight CFS columns accelerated corrosion by the outdoor periodic spray test. The thin shell finite element (FE) eigen-buckling analysis was also carried out to reveal the influence of corrosion surface characteristics, corrosion depth, corrosion location and corrosion area on the elastic local buckling behaviour of the plates with four simply supported edges. The accuracy of the proposed formulas for calculating the elastic local buckling stress of the corroded plates and columns was assessed through extensive parameter studies. The results indicated that for the plates considering corrosion surface characteristics, the maximum deformation area of local buckling was located at the plates with the minimum average section area. For the plates with localized corrosion, the main buckling shape of the plates changed from one half-wave to two half-wave with the increase in corrosion area length. The elastic local buckling stress decreased gradually with the increase in corrosion area width and length. In addition, the elastic local buckling stress decreased slowly when corrosion area thickness was relatively large, and then tends to accelerate with the reduction in corrosion area thickness. The distance from the corrosion area to the transverse and longitudinal centerline of the plate had little effect on the elastic local buckling stress. Finally, the calculation formula of the elastic local buckling stress of the corroded plates and CFS columns was proposed.

This study is aimed at exploring the direction and characteristics of Japanese medical facility improvement in each area, a move to strengthen local medical services. Also, this study is intended to establish implications for Korea, which has similar social conditions as Japan's. Based on the findings, Japanese medical facility improvement has the following characteristics. First, as for medical service supply system, the linkage between facilities was being strengthened. The purpose is to share the functions and roles of limited medical facilities. It allows patients to receive complete medical services in one area. Second, local public health facilities were consolidated to boost their management efficiency and to improvement their original functions. Third, local medical facility roles were divided into different levels. The purpose is to treat patients more efficiently depending on their diseases. In other words, the cooperative medical system was strengthened by dividing the roles of medical facilities. It is aimed at treating each patient more systematically depending on their conditions in line with the treatment stage. The findings suggest the following for Korea. In order to supply and maintain stable medical services regionally in line with social changes, functional issues of medical facilities should be tackled consistently and systematically.

We performed the numerical analysis on the characteristics of indoor air quality and local supply index with a variation of supply · exhaust airflow rate. We analyzed the local supply index and carbon dioxide concentration at the room and breathing zone with respect to the variation of the supply · exhaust airflow rate. From the numerical results, we found that local supply index was affected but carbon dioxide concentration was hardly affected by the variation of the airflow rate in the room. And we also knew that carbon dioxide concentration was raised in despite of the increment of the supply airflow rate in the breathing zone. After this study it is necessary to analyze the local exhaust index when we evaluate the state of the ventilation in the room.

Perennial stipitate kelps are globally distributed and individual species can inhabit broad latitudinal ranges, expressing notably longevous persistence. Despite the foundational role kelps provide to their communities, little is known about the variability in persistence of the stipitate kelps at local spatial scales. We studied the population persistence of Eisenia arborea, a heat- and wave force-tolerant perennial stipitate kelp with a distributional range extending from British Columbia to south of the range limit of all other northeast Pacific kelps, in Baja California Sur, Mexico. Persistence characteristics for E. arborea among sites were compared and used to test the hypothesis that stand persistence varied at local spatial scales around Isla Natividad, a Pacific island off the Baja California peninsula with documented spatiotemporal environmental heterogeneity. Collected individuals around the island were "aged" using the previously validated age estimation technique of counting annual cortical dark rings. After detecting no significant differences among sites in the covariation between estimated ages for collected individuals and stipe length, we utilized in-situ population-level stipe length measurements to more rapidly predict age structures within six stands around the island. Predicted age structures, and associated stand densities, revealed persistence characteristics and density varied at local scales and a strong positive relationship existed between stand density and stand mean and maximum ages. We speculate that stands responded differently to deterministic influences (e.g., the 2014-2016 marine heatwave and / or competition with Macrocystis) resulting in heterogenous local persistence of this foundation species.

This research aims to analyze the external activities of local governments in South Korea from the perspective of the developing trends in city diplomacy, contrary to the conventional and narrow concept regarding local government's international exchange and cooperation as a public diplomacy. In detail, this research intends to illustrate the following: first, to differentiate South Korean local governments' growing commitment to international affairs from public diplomacy; second, to highlight the integration of public diplomacy with other forms of diplomacy within the framework of city diplomacy. This research argues that city diplomacy in South Korea has gradually shown the following three trends and characteristics. First, South Korean local governments have recognized the importance of participating in multilateral diplomacy via city networks to find compelling solutions to non-traditional and transnational security threats. They perceive this external activity as an opportunity for policy sharing and problem-solving with foreign partners. Second, local governments in South Korea have been fostering various ways to institutionalize their involvement in foreign affairs and organizations, such as amendments to related laws and the launching of task forces, to pursue so-called sustainable and systematic international exchange and cooperation. Lastly, South Korean local governments have constructed multiple channels and multilevel governance in the form of public-private partnerships to enhance policy expertise and cope with diverse agendas.

Color, texture, and shape act as important information for images in human recognition. For content-based image retrieval, many studies have combined color, texture, and shape features to improve the retrieval performance. However, there have not been many powerful methods for combining all color, texture, and shape features. This study proposes a content-based image retrieval method that uses the combined local and global features of color, texture, and shape. The color features are extracted from the color autocorrelogram; the texture features are extracted from the magnitude of a complete local binary pattern and the Gabor local correlation revealing local image characteristics; and the shape features are extracted from singular value decomposition that reflects global image characteristics. In this work, an experiment is performed to compare the proposed method with those that use our partial features and some existing techniques. The results show an average precision that is 19.60% higher than those of existing methods and 9.09% higher than those of recent ones. In conclusion, our proposed method is superior over other methods in terms of retrieval performance.

간판은 점포의 첫인상과 지역의 전반적인 경관을 형성하는 것에 중추적인 역할을 한다. 우리나라 정부는 도시경관을 쾌적화하고 지역 상권을 활성화하기 위해 2012년부터 매년 간판 개선 사업을 시행하고 있다. 특히 최근에는 지역의 특성과 어울리는 간판을 조성하려는 노력을 기울이고 있다. 이 연구는 사업의 최근 동향을 토대로 간판을 개선할 때 지역의 특성을 반영하는 것이 점포와 지역에 어떤 영향을 주는지를 정보성·오락성·방해성의 매개 역할을 중심으로 밝히고자 했다. 이를 위해 간판 개선 지역에 방문한 경험이 있는 학부생과 대학원생 150명을 대상으로 설문조사를 실시했다. 연구 결과, 간판의 지역 적합성은 정보성과 오락성을 매개하여 점포 방문 의도와 지역 방문 의도에 긍정적인 영향을 주는 것으로 나타났다. 이 구조적 관계에서 방해성은 유의한 영향력을 가지지 않았다. 이 연구의 결과는 간판 및 간판 개선에 관한 학술적 이해의 폭을 넓히는 것에 공헌하며, 소상공인과 정부 기관 및 지방자치단체 실무자에게 지역 특성을 반영한 간판의 실효성을 시사한다.
