  • 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.

  • 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.

  • This research is to develop the Web-Based Ventilator Management Education Program that reflects the needs of nursing site nursing which is intended to help nursing duties. ISD model-building process has been developed for the analysis, design, development, operation, and evaluation of methods. The education program was developed from April to July 2011, and SPSS 18.0 was used for data analysis. The analysis stage, document review and requirement analysis, content analysis, learner analysis, technology and environment analysis have been executed. Through the processes, higher education requirements for the practical ventilator, a large number of subjects under the age of 30, and the career of less than 3 years of ICU were searched. At the design stage, the education content that was presented by the content expert group was executed in information design, mutual interaction design, synchronization design through discussion with program experts. At the development stage, author made the story flow and gathered data and integrated it through the review of related document and data. At the operation and evaluation stage, author executed the developed program and revised and supplemented it on the basis of the evaluation results through the experts and subjects evaluation. The Web-Based Ventilator Management Education Program could contribute to the improvement of nursing because the program has been developed to reflect the diverse needs of nursing practice in the process of building program.

  • 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.
