  • This study which was started to identify the factors that change the security level of military organizations, analyzed the data collected from articles written by the active officers in the Defense Daily Journal hoping to improve the military security level by the qualitative research method called Grounded Theory, and establish causal relationship how organizational members respond to insider security threats. As a result of the analysis, the causal condition is 'the security threat of the insider', the contextual condition is 'the specificity of the military organization', the central phenomenon is 'the conflict of values as a soldier', the arbitrary condition is 'the security consciousness', Strategy is 'the responds to security threats', and the result was 'security level change'. The core categories can be presented as 'the degree of conflict of values on insider security threats' and two hypotheses have been derived. First, the members of the military organization strongly felt the conflict of values about security threat as the tendency to emphasize security was strong, and they helped to develop the security level of organization by responding strongly. Second, the stronger the tendency to focus on colleagues, respond weakly to security threats. And it undermines the security level of the organization. Finally, in order to improve the security level of the organization, it is necessary to establish a solid security consciousness and to make institutional development to support it.

  • Recently the first stage of construction for Busan new port emerged over the sea surface at the north container terminal site. With this, there are lot of discussions and debates on increasing the water depth at the approaching channel and mooring basin from the existing 15m to 18m by dredging work in order to be able to serve 12,000TEU containership, and at the same time, correction to the reclamation plan of hinterland at the part of Undong Bay of the new port site. Since the attack of typhoon 'Maemi' in 2003, it is expected that the design wave parameters for coastal and harbor structures in this area would be somewhat changed and so the extreme wave condition at each terminal and tranquility of berthing area does, and therefore, it is necessary to analyze the tranquility at each berth. Hence in this study, we constructed a wave model for these conditions and performed simulation together with the circulation model simulation, compared with the field data collected. The result showed the increase of the harbor response throughout the basin but not severe condition. However, a certain location needs to be prepared for the rough sea condition when a severe typhoon hit the site.

  • Regional representative libraries are installing joint preservation archives to solve the problem of lack of preservation space in libraries. This study conducted a survey of public library librarians through a questionnaire survey and an FGI method in order to prepare specific operational policies and implementation plans for the Chungnam Library Joint Preservation Archive, which is a regional representative library. Based on this, an operation policy and implementation plan suitable for the common preservation and use of printed and digital data, which is the goal of the Common Preservation Archive, was proposed. As a result of the study, first, the joint preservation library of the Chungnam Library should first transfer books and serials along with ownership in consideration of the condition and demand of the preservation space of participating libraries. Second, it is necessary to establish an operation management system that can be used by all participating libraries in order to quickly and conveniently operate the joint preservation data center and connect it with a cloud-based integrated data management system. Third, a plan for digitizing and archiving data that was judged to be digitized in the Common Preservation Archive was proposed.

  • Purpose - Korea has a better geographical location than other nations in the Northeast Asian region. This means that Korea has an opportunity to become the center of international physical distribution in Northeast Asia. Korea should take advantage of this opportunity by exploring appropriate strategies to achieve this goal, assuming government willingness, with a view to capitalizing on the geographical advantage of the Korean peninsula and constructing a comprehensive physical distribution network system. If we prepare for this scenario, Korea could become the center of international physical distribution in Northeast Asia. Research design, data, and methodology - This study has the purpose of determining how shipping companies form partnerships with third-party logistics providers, and the relevant implications. The survey methods used were personal interview and a questionnaire distributed through e-mail, fax, mail, and telephone. A total of 600 questionnaires were distributed, out of which 285 were returned. Of the collected questionnaires, 10 were excluded because of insufficient content, leaving 275 to be used in the study as available valid samples. The data that was collected from these samples was analyzed using the data coating process and by employing a statistical package program. Results - Flexible policies, administration, and systems will be needed to create better business practices. In this dissertation, first and foremost, the results reveal that in order to become the center of Northeast Asian logistics, Korea must transition into a new paradigm based on the current economic and social systems that have stemmed from bureaucracy, inflexibility, chauvinism, and egalitarianism. Flexible policies, administration, and systems will be required to create better business practices. Domestic logistics corporations need to occupy a strategic logistics hub, create a logistics network, and activate value-added logistics business strategies by ensuring significant manpower and by building a logistics information system to strengthen their competitive edge, creating an improved system. Conclusions - In this dissertation, first and foremost, we point out that in order to become a center of North East Logistics, Korea should change to a new paradigm from the old one based on current economic and social systems that have stemmed from bureaucracy, inflexibility, chauvinism, and egalitarianism. More reasonable business laws, systems, and policies based on market-driven flexibility and transparency should be created. Moreover, social norms and rules should be reasonably established, to accomplish political and social security. Korea has to cultivate a culture of tolerance for foreign companies. This involves a change of paradigm for the development of the capital city and satellite cities. It will take a powerful task force or organization to plan and execute the vision that aims to meet these needs, accomplish the necessary goals, use the appropriate system effectively, and make Korea a key country in the field of Northeast Asian logistics.

  • This study was performed to clarify 'jajonshim' which is different from self-esteem in its social representation and concept in Korean society. In order to refine the notion of 'jajonshim', we first referred to literature and short essay on jajonshim and analyzed its cultural meaning and social representation in Korea. As a result, jajonshim was considered necessary condition for human beings in Korean culture. Although jajonshim was not well recognized normally, it became critical when it was threatened by others and considered to be what one must save as well. Furthermore, the ground theory designed by Strauss and Corbin was utilized in order to analyze Korean interviewees' experience of jajonshim. Koreans believed that their jajonshim was injured when others disrespected their values, which consequently produced negative emotions. When their jajonshim was damaged, people also used 3 coping strategies to recover it. Based on the results, jajonshim was distinguished from self-esteem. First, jajonshim is a type of self-awareness people experience when they are disrespected; thus, it is different from self-esteem which is maintained stable regardless of any events or situations. Second, unlike self-esteem which is solely evaluated by oneself, jajonshim is evaluated by other people's point of view. This study shows that jajonshim exists in the context of Korean culture and has significance in clarifying the cognitive structure and experience process of jajonshim.

  • Knitwear has been used as an active and functional clothing item due to its flexible and soft nature. Diverse design expressions have made knitwear into an essential fashion item for people today, who are constantly seeking for ways to display their individualism. The purpose of this study is to analyze the actual wearing conditions, and the preferred designs of knitwear for female college students in order to provide a baseline data, which can be used to develop knitwear designs for the subjects of the study. Survey by questionnaire of 135 female college students in 3 universities in Seoul were analysed. The results of the study are as follows: First, the most owned knitwear were sweaters and cardigans. Knitwear was viewed as soft and warm, as well as versatile. It was not restricted to certain sizes, and was comfortable to wear for different activities. Seound, the most preferred items were sweaters and cardigans. The most preferred styles were round neckline sweaters and open V-neckline cardigans. Third, the most preferred designs were plain designs with achromatic colors and wool-blended fabrics. The most preferred images were simple images. The most preferred fit was loose enough for little bit of room inside. Fourth, appropriateness and design of the knitwear were assessed during the purchasing stage. the most preferred method of purchase was purchasing via online stores after researching the knitwear through various channels, such as store visits and the Internet. The preferred price of knitwear was below 100,000 KRW. Fifth, the most common complaints were as follows: changes in the shape and quality of the knitwear after a wash, appearance of nap, and loose threads. In short, it is necessary for female college students to develop high quality knitwear with designs that can display individuality, while being simple.

  • In this paper, we consider the scheduling of SE(switching element)-disjoint multicasting in photonic Banyan-type switching networks constructed with directional couplers. This ensures that at most, one connection holds each SE in a given time thus, neither crosstalk nor blocking will arise in the network. Such multicasting usually takes several routing rounds hence, it is desirable to keep the number of rounds(i.e., scheduling length) to a minimum. We first present the necessary and sufficient condition for connections to pass through a common SE(i.e., make crosstalk) in the photonic Banyan-type networks capable of supporting one-to-many connections. With definition of uniquely splitting a multicast connection into distinct subconnections, the crosstalk relationship of a set of connections is represented by a graph model. In order to analyze the worst case crosstalk we characterize the upper bound on the degree of the graph. The successor paper(Part II)[14] is devoted to the scheduling algorithm and the upper bound on the scheduling length. Comparison with related results is made in detail.

  • Purpose: Laws and regulations of land use are enormous, and the appliance of regulations is overlapped redundantly. Therefore, there are many problems such as time consuming in the process, limiting individual property rights, and interrupting enterprises' economic activities. This study will discuss problems of redundant regulations of land use and its improvement by figuring out current regulations of land use in Gyeonggi-do, one of provinces which applies the most various regulations of land use. Method: This study reviews laws on national land-use planning system and characteristics of land-use regulation in Korea. The extent of the review is limited to "framework act on the regulation of land use" with categories of national land, urban planing, architecture, etc. Through case studies in Gyeonggi-do, the status and problems of redundant regulations of land use are defined. For example, it is overlapped in "Seoul Metropolitan Area Readjustment Planning Act", Development Restriction Zone, Paldang Special District, and so on. It is mainly referred to 2015 Gyeonggi-do land-use restriction map. Result: First, Gyeonggi-do confronts many problems related to the development restrictions and the financial increasement for environmental management by redundant regulations. The development restrictions include supplying additional land for industrial use, relocating colleges, and height limitation relating to military facilities. Second, in order to organize redundant regulations, it is required to combine similar regulations and adjust through communication system among other departments. Third, regulations should consider unique local condition of each district. Lastly, efficient application of regulations is necessary so as to maximize the function of land, protect individual property rights, and stimulate local development.

  • When the wind turbine is used in cold regions, the mechanical properties and dimension stability of the blade will be changed. The proposal of this paper is to test the durability of the blade for wind turbine. It is necessary to select the most comfortable materials and fabrication processes for more stable wind turbine blade in cold regions. To select the most comfortable materials and processes, the static strength has to know through the tensile static tests at the severe condition as cold regions. First, the tensile static specimens made by RIM (Resin injection molding) process & vacuum bagging process with reinforcement materials and resin. Tensile static tests were carried out on three laminate lay-ups (carbon prepreg, carbon fiber dry fabric and glass fiber dry fabric) at different test temperature($24^{\circ}$, $-30^{\circ}$), determining properties such as the mechanical strength, stiffness and strain to failure. At different test temperature, in order to test the tensile strengths of these specimens used the low temperature chamber. Next, the results of this test were compared with each other. Finally, the most comfortable materials and fabrication processes can select based on these results. The results show the changes in the static behavior of three laminate lay-ups at different test temperatures. At low temperatures, the static strengths are higher than the ones at room temperature.
