A conventional track structure system of rails ties ballast subballast and subgrade. An adequate engineering analysis require consideration of all major components of track system. This paper briefly reviews existing methods of track analysis and presents a new model based of the examination of the Tallbot Model. The new model has been validated by comparision with settlements from other model.

연고가 소비자들의 제품구매와 점포선택에 영향을 미치는 것으로 보인다. 그러나 이에 대한 실증적인 연구가 밝표된 적이 거의 없다. 본 논문에서는 관계마케팅의 관점에서 세 가지의 사회적연고의 형태가 소비자의 만족, 신뢰, 압박감에 어떠한 영향을 미치는 가를 검증하였다. 대체적으로 종교적 관계나 가족적 관계는 소비자의 만족, 신뢰와 압박감에 영향을 미치는 것으로 나타났다.

본 연구의 목적은 부스러기사랑나눔회의 결연아동을 위한 결연 프로그램이 아동에게 미치는 영향을 알아보기 위해 부스러기사랑나눔회 결연아동 249명을 대상으로 설문조사와 이에 대한 분석을 진행하였다. 장학생의 장학금에 대한 만족도와의 관계성을 확인하기 위하여 SPSS Statistics23 프로그램을 활용하여 상관분석을 실시하고, 장학생과 장학관리기관과의 관계성이 미치는 영향을 확인하기 위하여 회귀분석을 실시하였다. 분석결과 아동이 장학금에 대한 만족도가 높을수록 진로성숙도와 어제의 행복감이 높은 것으로 나타났으며, 부스러기장학금 수혜에 대해 만족할수록 자아존중감과 진로성숙도, 그리고 어제의 행복감이 높아지는 것으로 확인되었다. 이러한 연구결과를 바탕으로 결연아동을 위한 지원 방안을 논의하였다.

The moment-curvature envelope describes the changes in the flexural capacity with deformation during a nonlinear analysis. Therefore, the moment-curvature analysis for reinforced concrete columns, indicating the available flexural strength and ductility, can be conducted providing the stress-strain relation for the concrete and steel are known. The moments and curvatures associated with increasing flexural deformations of the column may be computed for various column axial loads by incrementing the curvature and satisfying the requirements of strain compatibility and equilibrium of forces. Clearly it is important to have accurate information concerning the complete stress-strain curve of confined high-strength concrete in order to conduct reliable moment-curvature analysis that assesses the ductility available from high-strength concrete columns. However, it is not easy to explicitly characterize the mechanical behavior of confined high-strength concrete because of various parameter values, such as the confinement type of rectilinear ties, the compressive strength of concrete, the volumetric ratic and strength of rectangular ties. So a stress-strain model is developed which can simulate complete inelastic moment-curvature relations of high-strength concrete columns.

This paper develops fashion products that express the beauty of Baekje through an investigation of the unique characteristics of Baekje artifacts. This work can promote the Baekje region and provide cultural goods for local festivals to improve the economic competitiveness of the area. Artifacts from the Muryongwangreung in Gongju (the capital city of Baekje during the Woongjin period)were reinterpreted into a more modern form. Among the Muryongwangreung artifacts, the king and queen's gold coffin as well as chignon ornaments were used as design motifs. These artifacts were stylized into motifs and developed into patterns using Adobe Illustrator CS3 and Adobe Photoshop CS3. The patterns were subsequently applied to the designs of scarves and ties. The color was selected using the CMYK colorway from the Gongju city logo subsequently, a total of 12 designs (including 6 ties and 6 scarves) were developed. The design developed from this research can be applied to diverse products to promote the area. Using the research as a foundation, fashion product development based on the local culture can have a significant impact on the establishment of the Baekje cultural identity and the competitiveness of the region.

Objectives: The goal of this paper is to examine the social network effects on post-traumatic sdress disorder (PTSD) in female North Korean immigrants who entered South Korea in 2007. Specifically, it attempts to verify if the density and composition of networks make a difference after controlling for the network size. Methods: A multivariate logistic regression is used to probe the effects of social networks using the North Korean Immigrant Panel data set. Because the data set had only completed its initial survey when this paper was written, the analysis was cross-sectional. Results: The size of the support networks was systematically related to PTSD. Female North Korean immigrants with more supporting ties were less likely to develop PTSD, even after controlling for other risk factors (odds-ratio for one more tie was 0.8). However, once we control for the size of the network, neither the density nor the composition of the networks remains statistically significant. Conclusions: The prevalence of the PTSD among female North Korean immigrants is alarmingly high, and regardless of the characteristics of supporting network members, the size of the supporting networks provides substantial protection. This implies that a simple strategy that focuses on increasing the number of supporting ties will be effective among North Korean immigrants who entered South Korea in recent years.

The goal of this study is to conceptually orientate optimized layouts of outrigger belt trusses which are in widespread use today in the design of tall buildings by strut-and-tie truss models utilizing a topology optimization method. In this study unknown strut-and-tie models are realized by using a typical SIMP method of topology optimization methods. In tradition strut-and-tie model designs find the appropriate strut-and-tie trusses along force paths with respect to elastic stress distribution, and then engineers or designers determine the most proper truss models by experience and intuition. It is linked to a trial-and-error procedure based on heuristic strategies. The presented strut-and tie model design by using SIMP provides that belt truss models are automatically and robustly produced by optimal layout information of struts-and-ties conforming to force paths without any trial-and-error. Numerical applications are studied to verify that outrigger belt trusses for tall buildings are optimally chosen by the proposed method for both static and dynamic responses.

This research empirically examined the determinants of competitive advantages and performance of Korean film industry from 1996 to 2003 over a sample of 396 movies. Especially, the effects of knowledge-based resources, social capital, product differentiation strategy, and market entry strategy on a film performance were hypothesized and empirically tested. Findings of this study are as follows; First, confirming the importance of knowledge-based resources in film industry, both the superior business track records of producers and the superior artistic track records of directors and actors had positive effects on film performance. Second, supporting social capital hypotheses, while the strong ties between directors and producers had positive effects, the strong ties between directors and actors had negative effects on film performance. Third, confirming the importance of product differentiation strategy, genre differentiation against competing films had positive effects on film performance. Finally, confirming the importance of market entry timing, the number of competing films released following a film opening within a week had negative effects on film performance. The findings of this research suggest that producers, directors, and actors are not only the critical knowledge-based resources to create competitive advantages indeed, but the pattern of relationships among them also systematically influences the film performance. Moreover, it is suggested that film performance may be improved by the proper genre differentiation and opening day selection.
