Humanities and social sciences researchers and database experts have teamed up to build a database of IPR materials prepared by the Institute of Pacific Relations (IPR). This paper presents the issues and solutions inherent in the database construction for ensuring the quality of IPR materials. For the accessibility of the database, we maintain the database on the Web so that researchers can access it via web browsers; for the convenience of the database construction, we provide an integrated interface that allows researchers to perform all tasks in it; for the completeness of IPR materials constructed, we support the responsible input and the responsible approval that identify responsibilities of each IPR material entered; and for the immediacy of the approval, we support an interactive approval process facilitating the input of researchers. We also use database design, query processing, transaction management, and search and sorting techniques to ensure the correctness of IPR materials entered. In particular, through concurrency control using existence dependency relationships between records, we ensure the correctness between the operating system files and their paths. Our future studies include content search, database download and upload, and copyright related work on IPR materials.

Objectives : As there was no sufficient research done on Sasang (four harms: 氣[qi], 血[blood], 痰[phlegm], and 鬱[congestion]), which serves as a precept in treatment of miscellaneous diseases, in contrast with 'Yang is always teeming whereas Yin is always scarce' and 'Sanghwa-ron', which are Judangye's major theories, I have come to work on it. I expect that with this, we can understand Judangye's medical theory and therapy for a variety of diseases. Methods : To begin with, I take a look at the definition of Sasang. And then, I make selections of theories and therapy related to Sasang from Gyeokchiyeoron(格致餘論) and Geumgweguhyeon(金匱鉤玄), which are Judangye's writings. My study follows the order of energy, blood, phlegm, and congestion. Results : Through Gyeokchiyeoron, I have learned more about Judangye's theory on how energy, blood, phlegm, and congestion cause diseases. And as for therapy, I have tapped into Geumgweguhyeon to use sagunja-tang(四君子湯) for drained energy, samul-tang(四物湯) for drained blood, ijin-tang(二陳湯) for phlegm, and wolguk-hwan(越鞠丸) for congestion, thus verifying the originality of Judangye's theory. Conclusions : "Judangye for miscellaneous diseases" was confirmed through his treatments for energy, blood, phlegm, and congestion. And his idea of Yang-eum(養陰 'nurturing yin') is now reflected in therapy for miscellaneous diseases, now serving as a study that provides a comprehensive understanding of Judangye's medical theories.

In recent years, the construction of golf course has been increasing very rapidIy and serious concern is paid to its environmental consequences both in Korea and in Japan. EIA systems as a major requirements for golf course developments emerged to reduce the adverse impact of their developments in Korea as well as in Japan. This study aims to compare EIA systems, procedures and methodologies employed between Korea and Japan in order to demonstrate the success and failure of EIAs in each country. The results of this study can be summarized as follows : 1) EIAs are systematically undertaken based upon law in Korea but on regulation in Japan. 2) Public participation Isn't encouraged in the Korean EIA procedure while the Japan EIA system involves public participation. 3) Korean EISs shall be prepared after the proposed projects are approved according to the related laws and be followed by the necessary procedures, but in the carte of Japan, EISs be prepared prior to their approval . 4) ELSs shall be prepared by agencies with special expertise with respect to 7he environmental impacts (appointed by government) or the sponsoring agencies themselves in Korea whereas they be prepared by agencies proposing the projects in japan. 5) EISs both in Korea and in Japan are characterized by cliches which may be unfamiliar to reviews and the public. 6) EIAs describe the existing presence and predict and evaluate that a development work influences the present conditions. Here Japan EIA treats mainly natural - and life environment, whereas Korean EIA dose social - and economic environment. And hence in the case of Japan is undertaken more quantitative and scientific analysis, whereas in the case of Korea is less. It is suggested that the key point to impact analysis is to use the correct concepts, fomulate the comparative studies of methodologies and find the methods that suit the decision as well as which country's own circumstances.

Handoff if the most Important feature for the user's mobility in a cellular communication system, which is related to resource reservation at nearby cells. For efficient resource reservation, mobility prediction has been reported as an effective means to decrease call dropping probability and to shorten handoff latency in wireless cellular environments. Several early proposed handoff schemes making use of tile user's movement history on a cell-by-cell basis work on the assumption that the user's movements are restricted to the indoor locations such as an office or a building. However, those algorithms cannot be applied to a micro-cell structure or a metropolis with complicated structure of roads. In this paper, to overcome those drawbacks we propose a new mobility prediction algorithm, which stores and uses the history of the user's positions within the current cell to predict the next cell.

The purpose of this study is to provide a reference for stage planning by analyzing current state of major theaters' stage space and understanding feedback from directors belonged to theaters. Each room in total 18 theaters' stage facilities was measured and their usage and requirements were analyzed on the spot. In addition, each director provided their experiential knowledge about appropriate stage composition for musical performance. The findings are as follow: under stage machinery is not needed for musical. Tour teams prefer to use their own show-deck for set conversion. On the other hand, over stage flying system needs to be able to deal with dense, fast, and accurate scene change. The size and location of the motor room needs to be carefully considered. The number of set battens is directly linked up with the size of the motor room, which should be located lower than the gridiron. As stage sets get bigger and complicated, the number of works at the gridiron is also increasing. The grating floor has to have enough strength coping with machines lifting heavy sets. Most sound control for musical performance is being done at F.O.H. these days rather that in the sound control room. It should equip enough work area and related infra especially for tour teams. 1st gallery needs to have enough effective width, power infra for lighting fixture, and strong guardrail. Lastly, the whole process of parking-unloading-transporting equipments and sets from loading dock to stage and vice versa needs to be efficient, and this has to be carefully considered from early stage of planning.

In the present paper, we offer a new flat shell finite element. It is the result of the combination of a membrane element and a bending element, both based on the strain-based formulation. It is known that $C^{\circ}$ plane membrane elements provide poor deflection and stress for problems where bending is dominant. In addition, they encounter continuity and compliance problems when they connect to C1 class plate elements. The reach of the present work is to surmount these problems when a membrane element is coupled with a thin plate element in order to construct a shell element. The membrane element used is a triangular element with four nodes, three nodes at the vertices of the triangle and the fourth one at its barycenter. Each node has three degrees of freedom, two translations and one rotation around the normal. The coefficients related to the degrees of freedom at the internal node are subsequently removed from the element stiffness matrix by using the static condensation technique. The interpolation functions of strain, displacements and stresses fields are developed from equilibrium conditions. The plate element used for the construction of the present shell element is a triangular four-node thin plate element based on Kirchhoff plate theory, the strain approach, the four fictitious node, the static condensation and the analytic integration. The shell element result of this combination is robust, competitive and efficient.

This research is devoted to investigate the bending and free vibration behaviour of laminated composite/sandwich plates and shells, by applying an analytical model based on a generalized and simple refined higher-order shear deformation theory (RHSDT) with four independent unknown variables. The kinematics of the proposed theoretical model is defined by an undetermined integral component and uses the hyperbolic shape function to include the effects of the transverse shear stresses through the plate/shell thickness; hence a shear correction factor is not required. The governing differential equations and associated boundary conditions are derived by employing the principle of virtual work and solved via Navier-type analytical procedure. To verify the validity and applicability of the present refined theory, some numerical results related to displacements, stresses and fundamental frequencies of simply supported laminated composite/sandwich plates and shells are presented and compared with those obtained by other shear deformation models considered in this paper. From the analysis, it can be concluded that the kinematics based on the undetermined integral component is very efficient, and its use leads to reach higher accuracy than conventional models in the study of laminated plates and shells.

Background: Glucocorticoids are commonly co-administered with chemotherapy to prevent drug-induced allergic reactions, nausea, and vomiting, and have anti-tumor functions clinically; however, the distinct effects of GC on subtypes of tumor cells, especially in breast cancer cells, are still not well understood. In this study, we aimed to clarify the effect of GC on subtypes of T47D breast cancer cells by focusing on apoptosis, cell organization and migration, and underluing molecular mechanisms. Materials and Methods: The cell scratch test was performed to observe the cell migration rate in T47D cells treated with dexamethasone (Dex). Hoechst and MTT assays were conducted to detect cell survival and rhodamine-labeled phalloidin staining to observe cytoskeleton dynamics. Related factors in the AKT/mTOR pathway were determined by Western blotting. Results: Dex treatment could effectively inhibit T47D breast cancer cell migration with disruption of the cytoskeletal dynamic organization. Moreover, the effect of Dex on cell migration and cytoskeleton may be mediated by AKT/mTOR/RhoA pathway. Although Dex inhibited T47D cell migration, it alone may not induce cell apoptosis in T47D cells. Conclusions: Dex in T47D human breast cancer cells could effectively inhibit cell migration by disrupting the cytoskeletal dynamic organization, which may be mediated by the AKT/mTOR/RhoA pathway. Our work suggests that glucocorticoid/Dex clinical use may prove helpful for the treatment of breast cancer metastasis.

The basic identity of the National Library of Korea(Sejong), opened in December 2013, is the specialized library focused on policy information service. Nevertheless, the library is not unfaithful to its identity. So researchers surveyed and analyzed the perception of the basic identity and role, utilization and satisfaction degress of various services, need and use for policy information and policy information service, and strategic and focused initiatives from stakeholders such as public officials, government-supported researchers, citizens living in Sejong city, and employees who work in the NLK(S). As a result, researchers suggested various strategies to expand the organizational size, to strengthen acquisition of domestic and foreign policy information, and to enhance national policy information service for related groups' satisfaction and dependence of policy information service for the NLK(S).
