  • A study on the measuring and evaluation of LSC(Least Square Center) roundness was carried out. The experimental set-up was made by index head and indicator, and the measuring data were compensated by a developed computer program. The results obtained are as follows : 1) An index head can conveniently be used to measure LSC roundness. 2) A program for calculating LSC roundness is developed. 3) Without a high quality roundnes measuring apparatus, LSC roundness can be measured and calculated by using index head and the developed program in machine shop as well as in a measuring room

  • A wheel/rail contact module for dynamics analysis of railway vehicles is developed. The developed module is based on non-linear contact and FASTSIM algorithm which calculates contact forces. And the module is incorporated into the general purpose program DADS using user-defined subroutines. The simulation results of this developed program is compared to those of the railway vehicle dynamics analysis program AGEM. Since the module is based on DADS, various simulation environments can be considered.

  • Purpose: This study was performed to verify the effect of rhythmic activity program on the elderly particularly their level of instrumental activities of daily living(IADL), depression and sleep. Method: The design of this study is one-group pretest-post test design. Three self-reported questionnaires were used as follows: first, the IADL Scale developed by Lawton and Brody(1969) and revised by Suh(1996) for measuring IADL, second, the Geriatric Depression Scale developed by Sheikh and Yesavage(1986) and revised by Song(1991) for measuring depression, third, Korean Sleep Scale developed by Oh, Song, & Kim(1998) for measuring sleep aspects; fourth, the applied version of Facial Pain Scale developed by Wong & Baker(1988) and revised by Song(2004) for measuring sleep quality. Twenty-seven elderlies carried out 50 minutes of rhythmic activity program for 4 weeks. Before and after the experiment, they were tested for IADL, depression and sleep. Collected data were processed using the SPSS/WIN 12.0 program analyzed by the frequency, percentage, mean and paired t-test. Results: The improvement in IADL of the elderly was not enhanced significantly but depression and sleep disorders significantly decreased. Conclusion: Rhythmic activity program is an effective nursing intervention for the elderly.

  • Objectives: The purpose of this study is to develop a health-promoting program centered on the university-health center and to provide a developed program for students and faculties. Methods: A survey was conducted of 719 female students and 238 faculties concerning their health-promoting programs. Based on the results of the survey, we developed programs that could be applied to students and faculties. After operating the programs, we developed further models by evaluating the effectiveness and satisfaction. Conclusions: We selected a comprehensive health-promoting program that included weight control, preventive inoculation, sex education and control of disease based on repsective needs. We also applied programs developed through collaboration with other departments from September 1998 to August, 1999. Users of the preventive inoculation-program increased by one point five during the year. Also, participants were generally satisfied with the weight control program and succeeded in reducing weight. We hope that we can set up this program and expand it by developing various other projects in Korea.

  • FPSO is widely used to develop deep sea oil fields and HHI has constructed ten(10) FPSOs. During these constructions, relevant structural design criteria such as yielding, buckling, fatigue, collision and impact strength were applied to verify structural safety. To apply the buckling strength evaluation for structures, the critical buckling stresses and applied stresses of relevant panels should be calculated. The plate and stiffened panels are to be idealized, which are needed much time and efforts by designers. Therefore, program development is necessary in order to evaluate the buckling strength conveniently and accurately. In this study, the buckling strength assessment system by using offshore code, DNV-RP-C201 was developed under MSC/PATRAN, pre-post program of finite element method. Graphic user interface program is written in MSC/PATRAN PCL functions. Source program to evaluate the buckling strength is developed in FORTRAN programming languages. The developed program is verified by comparing with the results of the Nauticus Hull developed by DNV Classification Society, and applied to the marine construction project conducted by Hyundai Heavy Industries LTD.

  • Design programs of tube-sheet for heat exchanger based on the related engineering society codes have been widely used. But it is not easy fer beginners to use the design programs. So we need to develop an easy program for design of tube-sheet for heat exchanger. This paper describes a developed design-program of tube-sheet fur heat exchanger. The developed program was coded on boiler theory and pressure vessel codes, provided by TEMA(Tubular Exchanger Manufactures Association) and ASME(American Society of Mechanical Engineers). Visual Basic, which is convenient for beginners to deal with, was used in the programming. Also a finite element analysis of tube-sheet for heat exchanger was carried to verify this developed program by using a commercial software, ANSYS. In the finite element analysis, tube and tube-sheet of heat exchanger were substituted by solid plate having equivalent properties for convenience of calculation. The thickness of tube-sheet obtained by the developed design-program was in good agreement with that of tube-sheet by FEA.

  • The purpose of this study was to develop a housing choice behavior program to cultivate housing value orientation among middle-school students. The importance of cultivating housing value orientation in middle school was examined by investigating the relationship between housing value orientation and housing choice behavior, following which a program was developed to cultivate housing value orientation based on various housing values. Housing choice behavior was defined as selecting the ownership type, housing type, housing size, and neighborhood environment of housing, and the program was developed in 12 sessions to understand housing values and cultivate housing value orientation through learning housing choice behavior. The features of this program were as follows. First, although housing choice behavior is not covered in middle-school home economics, the 2015 revised national curriculum and current middle-school textbooks were analyzed and developed in consideration of the level available in schools. Second, it was possible to develop a housing value orientation that encompasses various housing values, including activities used to consider such values as the basis for housing choice behavior by each sessions. Third, the program was meaningful in that it developed practical problem-solving and living independence skills through learning activities, including available sites, experience cases, and housing welfare that cannot be experienced directly or indirectly.

  • A wind turbine simulation program for the coupled dynamics of aerodynamics, elasticity, multi-body dynamics and controls of turbine is newly developed by combining an aero-elastic code and a multi-body dynamics code. The aero-elastic code, based on the blade momentum theory and generalized dynamic wake theory, is developed by NREL(National Renewable Energy Laboratory, USA). The multi-body dynamics code is commercial one which is capable of accounting for geometric nonlinearity and twist deflection. A turbulent wind load case is simulated for the NREL 5-MW baseline wind turbine model by the developed program and FAST. As a result, the two results agree well enough to verify the reliability of the developed program.
