전례적인 천문측량방법으로 연직선편차나 천문좌표를 결정하기 위해서는 별을 관측해야 하며 기상조건, 주변환경, 관측시간 및 측정기기 취급의 어려움 등 많은 제약조건이 수반되므로 좀더 효율적인 측정방법이 요구되고 있다. 본 연구에서는 WGS84좌표와 정표고를 이용하여 연직선 편차, 천문경도, 천문위도 및 천문방위각을 산정할 수 있는 프로그램을 구성하고 국내에 있는 10개의 천문점과 인접한 측점들에 대한 GPS 관측으로부터 천문성과를 산출하고 전통적인 천문측량방식 및 최신의 지구중력장모델(EGM96)에 의한 결과와도 비교 검토하므로서 GPS에 의한 연직선편차와 천문좌표의 산정법을 제시한 것이다.

Nursing education in Korea has made rapid progress recently. There is .: great deal of support with approval and encouragement of this progress. However, much disapproval of its validity has asserted some restraints on it. The aims of nursing education should be based on the principle that education is planned according to tile need much research has been made with such a viewpoint but much still remains unclear. The present study is aimed at establishing the needs for nursing manpower based on the biological demand for medical care. The needs for nursing manpower have been emphasized by many researchers and authorities on nursing education, and the prevailing medical trends also demand it. In this study, through the study of various hooks and records concerned, and the compiling of data analysis and questionnaires, I came to the following figures for the proposed needs of nursing manpower: There figures are greater than those calculated by another method by the government research program but it shows approximately the same final figure as that of the government report for the end of the target year. With these findings, I concluded that: 1) As the final purpose of the government medical project is to fulfill the needs of the national health (that is, to support the national needs for medical care), the plan of this project should follow the theory of biological demand for medical care, recognizing that the numbers will increase gradually. 2) Qualitative growth, based on the advanced and specialized nursing profession. should be promoted to meet the rapid growth of the medical needs of the nation in addition to promoting of investments for the facilities. and of the preparatory investments for education needs. 3) For efficient and economic utilization of nursing manpower, the improvement of wages, and the offering of free education is necessary. 4) Amendments to the low promising innovation and advancement of medical treatment; preparation of a national fund for medical care; and, changing of national attitudes to bring about greater concern are desirable.

PURPOSE. The purpose of this study was to propose finite element (FE) modeling methods for predicting stress distributions on teeth and mandible under chewing action. MATERIALS AND METHODS. For FE model generation, CT images of skull were translated into 3D FE models, and static analysis was performed considering linear material behaviors and nonlinear geometrical effect. To find out proper boundary and loading conditions, parametric studies were performed with various areas and directions of restraints and loading. The loading directions are prescribed to be same as direction of masseter muscle, which was referred from anatomy chart and CT image. From the analysis, strain and stress distributions of teeth and mandible were obtained and compared with experimental data for model validation. RESULTS. As a result of FE analysis, the optimized boundary condition was chosen such that 8 teeth were fixed in all directions and condyloid process was fixed in all directions except for forward and backward directions. Also, fixing a part of mandible in a lateral direction, where medial pterygoid muscle was attached, gave the more proper analytical results. Loading was prescribed in a same direction as masseter muscle. The tendency of strain distributions between the teeth predicted from the proposed model were compared with experimental results and showed good agreements. CONCLUSION. This study proposes cost efficient FE modeling method for predicting stress distributions on teeth and mandible under chewing action. The proposed modeling method is validated with experimental data and can further be used to evaluate structural safety of dental prosthesis.

Problems and improvemental measures for the historical inquiry of TV drama costumes and for the reproduction of them were investigated. For this study, the MBC historical drama 'The way of the Great King' started on march 24 in 1998 and ended on september 26 in 1998 was selected as the subject. The reasons why the drama was selected are as follows. First, the historical background was the time of King Young ＆ drama introduced various kinds of costumes Joungjo, which is the starting era of traditional costumes peculiar to Korea. Second, the based on the historical inquiry of that time. There is a limitation in the process of historical inquiry about the costumes of that time because we don't have enough research data such as relics, remains, references, literary works, pictures, etc. Although, in some cases, exact historical inquiry about the costumes were made, they could not be reproduced in the original forms due to several reasons: the absence of the materials of that time, structural changes including length and size for convenience of action, alterations of the manufacturing method for the reuse, addition of the gorgeous and various olors for the enhancement of image quality, variations in colors according to the actor's character, modulations of the structures and colors by the producer's intention, and the restraints in time and money for manufacturing. In view of these situations, it seems to be difficult for us to settle the problems occurring between the historical inquiry about the traditional costumes and the reproduction of them in drama. However, the costumes presented in historical drama have the meanings to provide informations of that time with TV audience. Therefore I think that it is necessary to narrow the gap between the historical inquiry of TV drama costumes and for the reproduction of hem, First, It should be restrained that each broadcasting stations show the costumes under the similar situations of the same age in different ways. Second, We need to unify the inquiry systems concerning historical drama costumes, In addition to this, it is also necessary for broadcasting stations to establish internet sites of traditional costumes for communication.

Cellular and castellated steel beams are used to obtain higher stiffness and bending capacity using the same weight of steel. In addition, the beam openings may be used as a pass for different mechanical fixtures such as ducts and pipes. The aim of this study is to investigate the effect of different parameters on both elastic and inelastic critical buckling stresses of steel web plates with openings. These parameters are plate aspect ratio; opening shape (circular or rectangular); end distance to the first opening; opening spacing; opening size; plate slenderness ratio; steel grade; and initial web imperfection. The web/flange interaction has been simplified by web edge restraints representing simply supported boundary conditions. A numerical parametric study has been performed through linear and nonlinear finite element (FE) models, where the FE results have been verified against both experimental and numerical results in the literature. The web plates are subject to in-plane linearly varying compression with different loading patterns, ranging from uniform compression to pure bending. A buckling stress modification factor (${\beta}$-factor) has been introduced as a ratio of buckling stress of web plate with openings to buckling stress of the corresponding solid web plate. The variation of ${\beta}$-factor against the aforementioned parameters has been reported. Furthermore, the critical plate slenderness ratio separating elastic buckling and yielding has been identified and discussed for two steel grades of DIN-17100, namely: ST-37/2 and ST-52/3. The FE results revealed that the minimum ${\beta}$-factor is 0.9 for web plates under uniform compression and 0.7 for those under both compression and tension.

시멘트 경화체에서 건조수축은 경화체내의 수분량이 감소하므로써 체적이 변화하게 되며, W/C가 높고 페이스트의 함유량이 많을수록 건조수축이 커진다고 알려져 있다. ECC의 경우, 굵은 골재를 포함하지 않기 때문에, 콘크리트에 비해서 더 많은 건조수축이 발생하게 된다. 만약, 양생중인 ECC에 구속이 작용할 경우, 일반 콘크리트 보다 큰 인장 응력이 발생하게 되며, ECC는 인장성능이 중요한 재료이므로 이러한 구속인장응력이 역학적 인장거동에 주는 영향을 고려해야 한다. 본 연구에서는 구속에 의해 발생한 응력이 ECC의 인장거동에 미치는 영향을 분석하고자 하였고, 구속여부를 달리하여 양생한 시험체에 직접인장 시험을 수행하여 역학적인 특성 변화를 관찰하였다. 그 결과, 구속응력에 따른 인장거동의 차이를 관찰하였고, 그 원인을 분석하였다.
