In order to understand the provision of social welfare in Korea, this study puts forward a method to measure and tracks the welfare mix, and applies the method to Korea. This is the goal of this study, which is in three parts. First, I critically review the concept of welfare pluralism and develop the welfare mix model, Second, I present a methodology and technique for measuring and systematically comparing the components of the welfare mix. Third, I examine the roles of five welfare providers including state, market, non-profit organization, enterprise and family in the welfare mix of Korea. This study argues that the welfare mix in Korea has some characteristics of 'residual state, expanded market, negligible voluntary sector, and protective family'. The state in Korea has played a relatively little role in the provision of social welfare, enforcing most Koreans being with a meagre social protection. Thus, most of the 'left' needs for social welfare has to be met in the private sector composed of market and enterprises. In addition, in a situation that self/mutual help through family or community is encouraged, the family has played an important role in the welfare mix. But the role of voluntary sector in the welfare mix has remained negligible. Consequently, the characteristics of the welfare mix in Korea can be best described by a welfare society rather than a welfare state.

This study is an analysis of the characteristics between the remodeling of an existing hospital and the remodeling of an existing hospital with the addition of a new annex. The comparison of the two remodeling methods focused on the difference of gross area, circulation system, improvement of hospital function, profitability of remodeling construction, and so on. The result of this study can be summed up as follows. The remodeling of an existing hospital with a new annex has the merit of enlarging new areas, promoting the function of the hospital, changing the inner circulation system, and facilitating the construction. However, it has the demerit of requiring too much money and expanded space for the construction. Therefore, it is possible to use the existing hospital remodeling method for small scale hospitals that do not have many patients, but it would be necessary for big scale hospitals with many patients to adopt the method of remodeling the existing hospital with the addition of an annex.

An information system to manage leveling data efficiently is presented. The system is consisted of input, adjustment, and query/answer module. The input module manipulating leveling data is based on the chain structure. The adjustment module adjusts the abservations by least squares method, and tests outlier by Baarda's data snooping method. The query/answer module serves user with the height and location of bench marks. In this system, the efficiency of works was increased as a result of removing the boring routine by applying the characteristics of leveling data. If necessary, for the special purpose, the system is expanded easily by appending some pertinent unit modules.

Thin-walled multicell box girders subjected to an eccentric load can he produced the three global behaviors of flexure, torsion, and distortion. Specially in railway bridges subjected to much eccentric load, it is quite important to evaluate influences of torsion and distortion. But it is very difficult to evaluate each influences of major behaviors numerically. If we can decompose an eccentric load P into flexural, torsional, and distortional forces. we can execute quantitative analysis each influences of major behaviors. Decomposition of Applied Load for Thin-walled Rectangular multi-cell box girders is reserched by Park, Nam- Hoi(Development of a multicell Box Beam Element Including Distortional Degrees of Freedom, 2003). But researches about trapezoidal multi-cell section is insufficient. So, this paper deals with multi-cell trapezoidal box girders. An expanded method, which is based on the force decomposition method for a single cell box girder given by Nakai and Yoo, is developed herein to decompose eccentric load Pinto flexural, torsional, and distortional forces. Derive formulas by decomposition of eccentric load is verified by 3D shell-modelling numerical analysis.

An appreciable number of Chinese firms have successfully expanded their businesses into foreign economics although they have limited resources. Advocating that home country government supports can mitigate firms' resource-disadvantages in international expansions, we attempted to investigate whether and how the Chinese government's support enables Chinese firms to compete in foreign markets. Based heavily on the knowledge-based theory of the firm and the resource-based theory of the firm, we developed a model that explain and predicts the effects of home-country government-supports on superior financial performance. The model was empirically tested using a accounting dataset regarding Chinese firms' 323 international expansion events from 2008 to 2015. Empirical evidence presents that the Chinese government's support has a positive effect on Chinese firms' international success and that these firms' marketing, technological, and managerial resources positively moderate the effect of the government support on the firms' international success. Nonetheless, because we employed an event-study method, the limitations of the method can be applied to the current research. In addition, because of the empirical context, the results of the research might lack generalizability. We, however, provided an understanding how firms from emerging countries can succeed in international expansions specifically when they have lack of resources for international competition.

In contemporary society, heterotopia is the law dominates thoughts and is the concept reconstituted spaces calls order in chaos. And that is the place which refuses the paradoxical and social custom and sometimes poses a danger and rise in rebel. The purpose of this study is to study how forms of clothing fluid form images are expressed in modern fashion develop body around in the spatial relationship between the body and its environment. The study method consider changed characterastics of fluid space through the heterotopia thinking system of Foucault Michel. Based on this method, the heterotopia space that appeared in the plastic arts in aspects of artistic significance and aesthetic value was examined. Based on the above discussion on modern fashion Fluid Form were expressed in any formative characteristics were considered. The results of this study are as follows. Fluidity is the transformed interaction. It expanded external representation of organic body structure and reconstructed flexible forms of dynamic structures continuously. Transformation is the new space structure. It constructed invisible transformation and developed convertible dress space by combining a variety of functional overlap and fold. Deconstruction was expressed structural forms, expanding the existing forms in the open structure which have ambiguous boundaries.

Recently, fluidic thrust vectoring methods have been preferably employed to control the movement of propulsive systems due to relatively simpler design and lower cost than mechanical thrust vectoring methods. For An application of the thrust vectoring to flight bodies, it is necessary to understand very complicated exhaust flows which are often subject to shock waves and boundary layer separation. But researches for the thrust vector control using counterflow have been few. In the present study, experiments have been performed to investigate the characteristics of supersonic jets controlled by a thrust vectoring method using counterflow. The primary jet is expanded through a two-dimensional primary nozzle shrouded by collars, and is deflected by the suction of the air near nozzle into an upper slot placed between the primary nozzle and the upper collar. A shadowgraph method is used to visualize the supersonic jet flowfields. Primary nozzle pressure ratios and suction nozzle pressure ratios are varied from 3.0 to 5.0, and from 0.2 to 1.0 respectively. The present experimental results showed that, for a given primary nozzle pressure ratio, a decrease in the suction nozzle pressure ratio produced an increased thrust vector angle. As the suction nozzle pressure ratios were increased and decreased, the hysteresis of the thrust vectoring was observed through the wall pressure distributions

Within the context of Structural Health Monitoring (SHM), it is often the case that structural systems are described by uncertainty, both with respect to their parameters and the characteristics of the input loads. For the purposes of system identification, efficient modeling procedures are of the essence for a fast and reliable computation of structural response while taking these uncertainties into account. In this work, a reduced order metamodeling framework is introduced for the challenging case of nonlinear structural systems subjected to earthquake excitation. The introduced metamodeling method is based on Nonlinear AutoRegressive models with eXogenous input (NARX), able to describe nonlinear dynamics, which are moreover characterized by random parameters utilized for the description of the uncertainty propagation. These random parameters, which include characteristics of the input excitation, are expanded onto a suitably defined finite-dimensional Polynomial Chaos (PC) basis and thus the resulting representation is fully described through a small number of deterministic coefficients of projection. The effectiveness of the proposed PC-NARX method is illustrated through its implementation on the metamodeling of a five-storey shear frame model paradigm for response in the region of plasticity, i.e., outside the commonly addressed linear elastic region. The added contribution of the introduced scheme is the ability of the proposed methodology to incorporate uncertainty into the simulation. The results demonstrate the efficiency of the proposed methodology for accurate prediction and simulation of the numerical model dynamics with a vast reduction of the required computational toll.

Domestic construction companies are suffering from financing difficulties in the wake of the economic slump in Korea and abroad. During this economic slump, real estate investment trusts (REITs), facilitators for improving financing and stimulating construction businesses, have increasingly expanded since their introduction in 2001. However, in terms of growth speed and marketing size, Korean REITs are falling behind those of other nations. The purpose of this study is to suggest a method for composing a portfolio using the Markowitz portfolio selection model to stimulate REITs. The main contents are as follows. First, a comparative analysis was conducted of increased REIT profit with the application of the Markowitz model and the average REIT profit rate from July 3, 2007, to July 21, 2008, during the investment analysis periods. The results showed that the total profit rate from the Markowitz model was about 10% higher than the average REIT profit rate. Second, the sensitivity was analyzed according to the portfolio's data-gathering and replacement cycle to measure the optimum cycle and yield. The six-mouth profit data collection period showed about 16% higher profits with the Markowitz model than with the REITs. The two-week portfolio change period resulted in about 11% higher profits with the Markowitz model than with the REITs.
