Conventional procedures to determine vertical deflections and astronomical coordinates require the stellar observations which be under restraints of clear night-time weather conditions, surrounding environment, long observation time and the use of instruments, etc. Therefore the more effective observation method subjugatting these problems has requested. The objective of this study is to propose method to compute vertical deflections, astronomical coordinates(latitude and longitude), and astronomical azimuth by mixing GPS observation results and orthometric heights. For this study, programmed the program which able to obtain the change in geoid undulation by using the GPS- determined geodetic height difference and the orthometric height difference, and GPS satellite surveying was performed at both ten points of astronomical points and four triangulation points around each astronomical station in South Korea. The Astronomical results determined from GPS observations compared to those determined from both conventional astronomical measurements and the recent earth gravitational Model(EGM96).

The purpose of this study is to figure out family member's perceptions of side rail use in geriatric hospital by Cavanagh's content analysis with in-depth interview. This finding of the study suggests that the six themes of these perceptions are precautionary safety supervision, movement convenience, ritualistic nursing, physical restraint, danger of wounds, and alternative methods in an older person ward, and that the cause of recognized perceptions is not based on actual events, but rather on relatives' perceived protective value. With the transition of medical industry environment, there is a significant emphasis on efficacy and effectiveness of practice, risk management and evidence-based practice. However, the issue of side rail use and physical restraints remains unsolved in care of older people. Nurses claim the necessity of regimented protocol and clarification from professional organization regarding the side rail use.

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.

This paper discusses entrepreneurship as a mean to overcome problems that arise from economic growth with no job growth and with aging population. In particular, this paper focuses on senior (elderly) entrepreneurship based on technology. It examines and defines restraints of various public and private sponsor programs for senior entrepreneurship. In comparison, Bridge Program of Finland was studied and its success factors are presented. Some of these success factors are enterprise-driven program operation, diverse education program focused on successful senior entrepreneurship, providing networking opportunities among entrepreneurs, and increased awareness in social responsibility of private enterprises. This paper suggests CBI (Corporate Business Incubator) in order to promote senior entrepreneurship. This study is expected to foster economic growth and job creation through utilizing increased elderly population in today's aging demographics. In addition, this study will be able to identify direction for government's role in boosting senior entrepreneurship.

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.

Drying shrinkage in the hardened cement is known to change in volume by decreasing the moisture content in the hardened body, and it is known that the higher the W / C and the higher the content of the paste, the larger the drying shrinkage. In the case of ECC, more drying shrinkage occurs compared to concrete, since it does not contain coarse aggregate. Since ECC is an important material for tensile performance, the effect of restrained tensile stress on mechanical tensile behavior should be considered. The purpose of this study is to analyze the effect of stress caused by restraint on the tensile behavior of ECC. The mechanical properties of the specimens were tested by uniaxial tension tests with different restraints. As a result, the difference of tensile behavior according to restraint stress was observed and the cause was analyzed.

This study was conducted to identify families' perception and attitude toward application of physical restraint(PR) in general neurological wards. The study is based on subjects from 70 family members who have cared patients applying PR. Data was collected using self-report questionnaires and reviewing of patients' medical records. 68.6% of subjects were female and the mean age was 47.9 years old. Family members were either sons, daughters or spouses. The questionnaires analyzed families' perceptions based on a score of 5, the results showed a mean score of 4.2, and items related to maintaining therapeutic tools scored the highest. The application of PR with two hands was perceived by families as more important than PR applied with one hand. In families' attitude toward PR, there was general agreement that families had the right to decide to apply and remove PR. Continuous education and information regarding PR is required to support families.
