본 연구는 최근 한국 사회복지서비스의 변화를 민영화이론, 복지혼합, 소비자주의 접근으로 설명하는 것이 제한적이라고 보고 서비스 행위자간 관계분석으로 변화를 설명하고자 하였다. 사회복지서비스의 네 행위자인 이용자, 전달자, 제공자, 정부가 맺는 여섯 차원의 관계에서 변화를 공식성과 평등성 이라는 기준으로 분석하였다. 이 결과 한국 사회복지서비스에서 행위자들의 관계가 온정적이고 시혜적인 성격의 비공식적이고 위계적인 관계에서 공식성과 평등성을 강화하는 방식으로 제도화되고 있음을 포착하였다. 이러한 관계는 계약적 방식에 기초하고 있으며 행위자 권리의 제도적 기초가 형성된 점이 의미 있는 변화로 발견되었다. 반면, 정부와 다른 행위자들과의 관계가 가지는 불명료성이 딜레마로 분석되었다. 이 딜레마는 사회복지서비스 공급에서 서비스 질 관리라는 정부의 역할을 구체화하면서 해결되어야 함을 제안하였다.

This study was carried out forecasting of pollution inflow of the Small Mountainous Catchment, namely; Seolma-cheon experimental catchment. Pollutographs of DO, BOD, T-N, Conductivity, T-p, pH. COD, SS from this catchment were obtained from in-situ data of total ten events using QUAL2E-PULS model. From the analysis results, between up stream(Sabang-bridge) and down stream (Memorial-bridge, outlet) obtained relation formula of water quality component. Determination coefficient of relation formula, Conductivity, COD, BOD, DO, pH, T-N, T-P, and SS showed high relation of $0.87{\sim}0.99$. The increases of DO, BOD, COD, and pH concentration of Memorial-bridge were associated with pollution inflow by road building far 2.25km from Sabang-bridge to down stream. The analysis results of QUAL2E-PULS simulation and up/down stream relation formula, pollution amounts of DO, BOD, COD and pH increased at Memorial-bridge and pollution source site. Therefore, pollution inflow can be forecasted exactly by up/down stream relation formula at pollution source site.

The objective of this research is to analyze how main social relation network of middle-aged women such as family, friends and neighbors, etc affects the preference for silver town. For this objective, structured questionnaires were distributed to 309 middle-aged women at the age of 40-59 years old living in Seoul and new cities of metropolitan area. Statistics such as ANOVA, Pearson Coefficient and Multiple Regression were adopted for statistical analysis. The main result of this research is as follows: First, housewives showed higher preference for silver town than people involved in other occupations. Second, though the relation of friends and neighbors among the social relation network of middle-aged women affected the preference for silver town, that of family did not affect significantly. The result of this research suggests that it is necessary to adopt policy considering the relation of friends and neighbors among the social relation network of middle-aged women so as to activate silver town.

An analytical procedure to analyze reinforced concrete (RC) beams subject to monotonic loadings is proposed on the basis of the moment-curvature relations of RC sections. Unlike previous analytical models which result the overestimation of stiffnesses and underestimation of structural deformations induced from ignoring the shear deformation and assuming perfect-bond condition between steel and concrete, the proposed relation considers the rigid-body-motion due to anchorage slip at the fixed end. The advantages of the proposed relation, compared with the previous numerical models, are on the promotion in effectiveness of analysis and reflection of influencing factors which must be considered in nonlinear analysis of RC beam by taking into account the nonlinear effects into the simplifying moment-curvature relation. Finally, correlation studies between analytical and experimental results are conducted to establish the applicability of the proposed model to the nonlinear analysis of RC structures.

This paper deals with the static analysis on the permanent magnet synchronous motors(PMSM) using transfer relation theorem according to the shaft materials, and adopts the analytical method to predict the magnetic field distribution and to calculate the electrical parameters by using Transfer Relation Theorem(TRT) in terms of 2-D model in polar coordinates system. In addition, the three types of PMSMS with different types of shafts, which are Iron cored, Air cored, Full-ring permanent magnet type shaft, are suggested in this research, and with those models, not only the analysis on the magnetic field distribution, the estimation of electrical parameters, but also their comparison with Finite Element Analysis(FEA) is processed.

Given high accretion rates close to the Eddington limit, narrow-line Seyfert 1 galaxies (NLS1) are arguably the most important AGN subclass in investigating the origin of the black hole mass-galaxy stellar velocity dispersion ($M_{BH}-{\sigma}$) relation. Currently, it is highly debated whether NLS1s are offset from the local $M_{BH}-{\sigma}$ relation. The controversy mainly comes from the fact that the [OIII] line width has been used as a proxy for stellar velocity dispersion due to the difficulty of measuring stellar velocity dispersion in NLS1s. Using the SDSS spectra of a sample of 105 NLS1, we performed multi-component fitting analysis to separate stellar absorption lines from strong AGN [FeII] complex in order to directly measure stellar velocity dispersion. We will present the result of decomposition analysis and discuss whether NLS1s follow the same $M_{BH}-{\sigma}$ relation based on the direct measurements of stellar velocity dispersion.

Liquid molding processes, such as resin transfer molding, involve resin flow through a porous medium inside a mold cavity. Numerical analysis of resin flow and mold filling is a very useful means for optimization of the manufacturing process. However, the numerical analysis is quite time consuming and requires a great deal of effort, since a separate numerical calculation is needed for every set of material properties, part size and injection conditions. The efforts can be appreciably reduced if similarity solutions are used instead of repeated numerical calculations. In this study, the similarity relations for pressure, resin velocity and flow front propagation are proposed to correlate another desired case from the already obtained numerical result. In other words, the model gives a correlation of flow induced variables between two different cases. The model was verified by comparing results obtained by the similarity relation and by independent numerical simulation.

Most studies of failure analysis in ductile metals have been based on the classical plasticity theory using the local constitutive relations. These frequently yields a physically unrealistic solution, in which a numerical prediction of the onset of a deformation localization shows an inherent mesh-size sensitivity. A one way to remedy the spurious mesh sensitivity resulted in the unreasonable results is to incorporate the non-local plasticity into the simulation model, which introduce an internal (material) length-scale parameter into the classical constitutive relations. In this paper, a non-local version of the modified Gurson constitutive relation has been introduced into the finite element formulation of the simulation for plane strain compression of the visco elastic-plastic void material. By introducing the non-local constitutive relations we could successfully removed the inherent mesh-size sensitivity for the prediction of the deformation localization. The effects of non-local constitutive relation are discussed in terms of the load-stroke curve and the strain distributions accross the shear band.

The purpose of this research is to identify the structure among determining factors focusing on knowledge transfer and analyze and prove the causal relation on knowledge transfer in Korean companies and public corporations. The results from the analysis of data collected in this study are as follows. First, forum among organization related factors has the positive relation with uncertainty in a significant level. Second, the higher the knowledge presentation and the ease of use are among information systems related factors, the lower the ambiguity and uncertainty are. Third, among process related factors, unification has the negative relation with ambiguity and uncertainty in a significant level. Fourth, a better manpower employment contributes to a worse ambiguity and uncertainty. Fifth, ambiguity has a negative relation with knowledge transfer. In conclusion, the factors that lower the ambiguity and facilitate knowledge transfer include information systems, unification, and manpower employment. These factors, however, influence on uncertainty, which turns out to be nothing to do with knowledge transfer.

Purpose - This study focuses on long-term orientation that can lead long-term partnership. A long-term orientation needs a trust and relation commitment between company. So in this study, the researcher conducts a dependent variable as a justice recognition and brand asset value to research model to find out casual relationship among quoted factors. Research design, data, and methodology - The focus of this study was employees who work in a liquor distribution company to figure out factors that effect on long-term relationship in b2b transaction. The development of the research model is based on the literature of the preceding research analysis of justice recognition, brand asset value, trust, relation commitment and long-term orientation. This study have constructs that defined operationally by previous studies, research model design that to figuring casual relationships among the quoted factors. From 2016 Sep. 1st to Oct. 30th, a questionnaire survey was conducted targeting employees who work in liquor distribution company. 176 survey data were used for empirical analysis to prove the research hypotheses. Results - The main results of this study's empirical methodology were as follows. First, procedural justice and interactive justice has a positive significant effect on trust and relation commitment. Also brand image, brand awareness and perceived quality has a positive significant effect on trust and relation commitment. Second, trust and relation commitment has a positive significant effect on long-term orientation. Every hypothesis adopted as the researcher designed for empirical study. Conclusions - Based on empirical results, this study confirmed that trust and relation commitment has empirical relationship with long-term orientation. Based on the analysis, the researcher provided managerial implication by setting 2 way path for making long-term orientation with business company. First path is procedural justice to relation commitment. It contains that procedural justice recognised while business transaction execution, consideration intension and relation development will happen in b2b. Second path is perceived quality to trust. It contains that the perceived quality recognised while business transaction execution, trust will increase rapidly. So when a business company wants to make a partnership, they have to consider procedural justice and perceived quality to make a long-term relationship.
