In this study, the seismic details of a concrete-encased, U-shaped steel beam-to-RC column connection were developed. Three specimens of the beam-to-column connection were tested under cyclic loading to evaluate the seismic performance of the connection. The test parameters were the beam depth and the column section shape. The depths of the composite beams were 610 and 710 mm, including the slab depth. For the RC columns, a square section and a circular section were used. Special details using diagonal re-bars and exterior diaphragm plates were used to strengthen the connections with the rectangular and circular columns, respectively. The test results showed that the specimens exhibited good strength, deformation, and energy dissipation capacities. The deformation capacity exceeded 4% interstory drift angle, which is the requirement for the Special Moment Frame.

The study proposes the method to cancel the scallop to avoid fracture of the circumstance of the scallop at H shape column-to-beam connection and reinforce at beam flange two faces with the cover plates and rib. A total of four specimens were tested to enhance seismic performance of building structure by reducing the frequency of stress concentration and preventing the brittle fracture of scallop. For this purpose, four full-scale test specimens were made and loaded with quasi-static reversed cyclic loading. The main analytical parameters are panel-zone-strength ratio, yield strengths, initial stiffness, total plastic rotation, contribution of each element to total plastic rotation and energy dissipation capability. For the specimens tested under repeated loading, the experimental result was satisfied with seismic performance requirement as the Special Moment Frames (SMF). The analysis results show that all of the test specimens were found to have good performance to 4% story drift and satisfied the criteria for the plastic roation capacity of SMFs that is 0.03 rad. according to the 1997 AISC seismic provision.

The purpose of this study was to investigate the applicability of periodic acid thiocarbohy-drazide silver proteinate, physical development (PA-TCH-SP, -PD) stain to the seminiferous tubules for the ultrastructural studies of Sertoli cell column and Sertoli cell processes. In the Sertoli cell cloumn and Sertoli cell processes, high concentration of the reactive granules were observed under transmission electronmicroscope (TEM) after PA-TCH-SP-PD stain. Also some reactive granules were seen in the spermatogonium cytoplasm, clearly. These reactive granules specifically stained with PA-TCH-SP, -PD make the Sertoli cell column, Sertoli cell processes and spermatogonium cytoplasm easy to distinguish from nucleus of the germ cells, spermatocyte, spermatid and residual body which did not contain the reactive granules. This result indicates that the PA-TCH-SP, -PD stain is superior to other traditional electronic double stain methods for the ultrastructural studies of Sertoli cell.

최근 글로벌화의 시대의 도래로 인하여 과거와는 달리 사람들의 국제적 이동이 빈번하게 발생하고 있다. 과거보다 잦은 국제 인구이동으로 인하여 각 국가 간 조세협약이 매우 중요해졌으며, 이제는 과세측면도 양국가간의 조세협약에 따라 과세를 하여야 한다. 본 연구는 이러한 상황 하에서 연금수령 시 국가 간 조세측면을 고려하였을 때 과세형평의 문제점을 살펴보고 이에 대한 개선방안을 제시하고자 한다. 과거에 비하여 최근의 연금세제 또한 많은 변화를 가져오고 있어 이제는 한 국가 내에서 만의 연금세제를 고려할 것이 아니라 글로벌화 시대에 부응하는 연금세제로의 변화가 필요하다. 이러한 주된 이유로는 국제이동 인력의 증가로 거주지국 과세원칙과 원천지국 과세원칙의 혼용뿐만 아니라 전세계소득(world-wide income)에 대하여 과세가 되므로 국제적인 이중과세의 위험에도 직면하게 되기 때문이다. 본 연구는 이러한 상황을 감안하여 최근 급증하고 있는 해외 이민지들에 대한 국제적 연금조세 측면을 살펴보고자 하였다. 해외에 거주하는 사학연금 가입자에게 발생하는 과세상의 문제점을 구체적으로 살펴보고 이에 대한 개선책을 살펴보고자 하였다. 해외거주 연금수령자는 국내에서 지급하는 연금에 대하여도 전세계소득으로 해외 세무당국에 보고를 하도록 하고 있는데, 국민연금은 각 국 간의 사회보장협약의 체결로 인하여 과세를 하지 않는 반면, 특수직역연금 수령에 대하여는 거주지국의 전세계소득에 포함되어 국외 거주지국 과세대상에 포함되는 문제점이 있다. 특히 캐나다에서 연금을 수령하는 경우에는 더욱 확연한 차이가 나타나게 된다. 본 연구에서는 다음과 같이 주장하고자 한다. 첫째, 한국·캐나다 조세협약 제18조의 수정을 통해 현행 사학연금 수급자의 연금소득에 대하여 비과세할 필요가 있다. 사회보장법률에 따라 지급하는 연금에 대하여 비과세하는 현행 문구를 한국의 공적연금으로부터 지급하는 연금으로 지급하는 급부로 수정할 필요가 있다. 둘째로 사회보장법률에 의해 지급하는 연금을 별도로 언급할 필요가 있다. 이를 통해 국민연금 가입자와 특수직역연금 가입자 간의 과세 형평성을 달성할 필요가 있다. 본 연구는 기존연구에서 간과되었던 연금세제의 국제적인 측면을 중심으로 국제적 인력의 이동에 따른 연금세제의 변화를 살펴보고자 하였다. 특히 최근에 우리나라 사람들이 가장 많이 이민을 가고 있는 캐나다를 중심으로 연금세제 측면을 살펴보고자 하였다는 측면에서 연구의 의의가 있다고 할 수 있다. 본 연구에서 제시된 정책적인 제안은 과세당국과 해외 연금수급자에게 편익을 제공할 것으로 본다.

This paper examines the relation between memory and consciousness,especially the independence between memory and memory consciousness. First,the phenomena of memory performance without memory consciousness, next the phenomena of memory consciousness without memory representation are dealt with. They are examined both in special cases(e,g.,brain damaged patients,under hypnosis,etc.) and in normal cases.In both case, we can find that memory and memory consciousness are independent each other and that memory representation is neither necessary nor sufficient conditions for memory consciousness. Lastly, the roles of memory consciousness in our daily information processing are dealt with. Especially, the importance of memory consciousness in normal social life and the problem of self consciousness are discussed.

This paper describes the design of dual-structured and thick-walled cylinder made of composites and special steel. The structure of special steel and composites reduce the weight of a product maintaining its property which is proper to the characteristics. Hence they are used in the fields, such as various ground weapons, aerospace and sports industries, where high elasticity and low weight are required. Thus in this study, the analysis was conducted to find the most proper composite application method changing its types and angle of laminates for the design. Through the comparison of the results, we suggest the method for composite application which is the most appropriate to the designing purpose of this study.

Corporations adopt a segmentation depends on the existence of target variables, in general. In this paper, for the case of no target variables, a strategy through segmentation is proposed for corporations having a special status based on the management index. In case of segmentation using cluster analysis, however, if one classify according to many variables then he will be in face of difficulties in characterizing. Therefore, after extracting representative factors by factor analysis, a segmentation method through 2 step cluster analysis is employed on the basis of these representative factors. As a result, six segmentation groups are found and the resulting strategy is proposed which strengthens prominent factors and makes up defective factors for each group.
