The multi type heat pump system may provide more energy savings and better environmental conditions than the single type heat pump system may do. In order to design a multi type heat pump system, it may be recommended to develop the system simulation program, which can predict the characteristics of the system such as unit capacities, power consumptions, and system COP's. In this study, the steady state simulation program of the multi type heat pump system was developed. The results from the simulation program were compared with those from the experimental tests which were performed in the environmental chamber, Cooling tests show 3.11% and 0.94% of error in capacity and COP, and heating tests show 3.30% and 1.90% of error in capacity and COP, respectively. Therefore, the steady state simulation program developed for this study can effectively be used for the design and the performance prediction of the multi type heat pump system.

A pilot education program was developed, applied in a practical setting, and evaluated. The program was designed on the basis of various educational philosophies and characteristics of parents as learners in various developmental stages. Specialists in the fields of parent education, early childhood education and child development were consulted. The comparative results between the pre- and post-tests of parent behaviors demonstrate that this program has a positive influence on the behaviors of participating patents. It was concluded that this program can be applied usefully in the development of and application to various parent education programs in Korea.

An education program for parents has been developed in order to meet the needs of those who have problems in rearing their children. The program has been applied two times to a middle size group of parents who live in the urban and the country. The effectiveness of the program has been evaluated by taking pre- and post-tests. The test results suggest that the program has been effective in improving the parent's knowledge on all of the following areas, such as, developmental characteristics, individual traits, learning attitudes cultivation, sex education, locus of self control, parenting behavior and communication skills.

A family life education program for caregiving families has been developed in order to help mitigate burden of those who provide caregiving for their older parents and to meet the needs of both caregiving families and parents. The program has been applied to a small group of people who have at least one living older parent. The effectiveness of the program has been evaluated by taking one pre-test and two post-tests. The test results suggest that the program has been effective in improving participants' knowledge on aging process, locus of self control, and relationships with parents.

The purpose of this study is to develop and evaluate a remarriage preparation program. Based on the system theory, strong family perspective, care & justice perspectives, and empirical research in this field,4 session remarriage preparation program is developed. Target population of this program is persons who remarry and persons who marry with remarried partner This program is evaluated in terms of the level of remarriage preparation and level of changing attitude after education in terms of self-esteem, cognition & knowledge of parent behavior in the remarried family, object evaluation of their future remarriage life. Future research, theoretical and practical implications are added.

The object-oriented programming languages are widely used in the modern software engineering. The procedural type FEM codes are still used because it is very hard and cost consuming job to re-code them into object-oriented programs. In this study, a FEM program was newly designed and coded with C++, an object-oriented language. Also a special programming technique, auto-loading technique was developed for open structured program, with which the extension and maintenance can be carried out easily. For example, the additions of element libraries to an existence FEM program do not require any modifications of the program.

A dynamic simulation program for pantograph-catenary system is developed based on a mode superposition method to predict current collection performance. Formulations for the dynamic simulation are presented in this paper. The number of modes which should be considered for a KTX catenary system is reviewed through frequency response analyses. The responses for GPU pantograph - KTX catenary system are simulated with various train speeds. The our simulation results are in reasonably good agreements with RTRI simulation program, SNCF simulation program, and BR simulation program.

An educational program for parent caregiving families has been developed with a view to help mitigate burdens of those who provide caring services for their aged parents and to meet the needs of both the caregiving middle-aged daughter-in-law and the parent. The program has been applied to a small group of people who at least one living aged parent. The effectiveness of the program has been evaluated by taking pre- and posttests. The result of the tests strongly suggest that the program has been effective in improving participatns' knowledge on aging process, confict solving and relationship with parent.

Background: Tetrahedral-mesh geometries can be used in the MCNP code, but the MCNP code accepts only the geometry in the Abaqus input file format; hence, the existing tetrahedral-mesh models first need to be converted to the Abacus input file format to be used in the MCNP code. In the present study, we developed a simple but useful computer program, TET2MCNP, for converting TetGen-generated tetrahedral-mesh models to the Abacus input file format. Materials and Methods: TET2MCNP is written in C++ and contains two components: one for converting a TetGen output file to the Abacus input file and the other for the reverse conversion process. The TET2MCP program also produces an MCNP input file. Further, the program provides some MCNP-specific functions: the maximum number of elements (i.e., tetrahedrons) per part can be limited, and the material density of each element can be transferred to the MCNP input file. Results and Discussion: To test the developed program, two tetrahedral-mesh models were generated using TetGen and converted to the Abaqus input file format using TET2MCNP. Subsequently, the converted files were used in the MCNP code to calculate the object- and organ-averaged absorbed dose in the sphere and phantom, respectively. The results show that the converted models provide, within statistical uncertainties, identical dose values to those obtained using the PHITS code, which uses the original tetrahedral-mesh models produced by the TetGen program. The results show that the developed program can successfully convert TetGen tetrahedral-mesh models to Abacus input files. Conclusion: In the present study, we have developed a computer program, TET2MCNP, which can be used to convert TetGen-generated tetrahedral-mesh models to the Abaqus input file format for use in the MCNP code. We believe this program will be used by many MCNP users for implementing complex tetrahedral-mesh models, including computational human phantoms, in the MCNP code.
