The purpose of this study was to identify the effect of choice theory focus group work on improving housewives' mental health. To achieve this goal. the book 'Warning: Psychiatry can be hazardous to your mental health' was utilized as a media to educate and debate. The subjects for the study were 24 housewives divided by 2 group. The instrument utilized were the Korean versions of Trait Anger Scale, Trait Anxiety Scale, Beck Depression Inventory, and Psychological Well-Being Scale. The participants were asked to complete the instruments before, after and in 5 weeks after the program. The results were as follows: First, Choice Theory Focus Group Work decreased trait anger, trait anxiety and depression compared to control group. Second, Choice Theory Focus Group Work increased Psychological Well-Being Scale compared to control group. The effect of the program was significant in improving mental health of the housewives and the effect was maintained up to 5 weeks after the program. The results of this study implied that Choice Theory Focus Group Work could be effective in improving mental health.

The present work have been developed the interpretation processor including the behavior of material failure and the separation phenomena under transient dynamic loading (the operation of explosive bolt) using AUTODYN V4.3, SoildWork 2003 and TrueGrid V2.1 programs. It has been demonstrated that the interpretation in ridge-cut explosive bolt under dynamic loading condition should be necessary to the appropriate failure model and the basic stress of bolt failure is the principal stress. The use of this interpretation processor developing the present work could be extensively helped to design the shape and the amount of explosives in the explosive bolt having a complex geometry. It is also proved that the interpretation processor approach is an accurate and effective analysis technique to evaluate the separation mechanism in explosive bolts.

This paper aims at developing a finite element program to predict undrained behavior of granular soil by using elasto-plastic constitutive model. A computer program developed by authors based on Christian's techniques for undrained behaviour of the soil has been employed coupled with Lade's single work-hardening model. Modification of the program for drained behaviour, considering restraint of volumetric strain, makes it possible to analize the underained behaviour. To validate the newly developed program, comparison of results was performed between numerical values and experimental data for Baekma river sand as well as Sacrmento river sand studied by Seed and Lee. The program is evaluated to have high accuracy.

Recently, both management and labor are interested in the increasing ratio of musculoskeletal disorders. And the developed countries make efforts to consider a counterplan such as prevention activity of musculoskeletal disorders and application possibility of ergonomic program, because musculoskeletal disorders take large portion out of occupational disease. Especially, small and medium enterprises have bigger problems due to the inferior work condition and environment in comparison with big businesses. This study is to introduce developed countries' cases such as WISE(Work Improvement in Small Enterprises) and OSHA Handbook for Small Businesses and to suggest the program of ergonomic management for small and medium enterprises having comparative difficulties against big businesses in improving work environment and managing ergonomic operations.

Design changes are inevitable areas of work for construction engineers as they occur frequently in the construction site, and are becoming a technical measure of the technical person to the design change. In this study, the purpose is to analyze by comparing the availability of excel and the enscised program during design changes through the case, and to present the efficiency of the the Cost-of-construction Program.

A complete dome structure is based on a basic dome modeling, and the basic dome modeling affects safety of the dome structure. In other to save the manufacture expenses, an optimum shape modeling of a dome structure is necessary work of before manufacture of the dome. In this study, modeling of the triangle optimum shape in the surface of an aluminum dome is more focused to optimize shape of the dome and save manufacture expenses. After being made the systematic procedure of the basic modeling, the programming work of the procedure is performed. The program is made by C language, and the trust of the program is proved by comparison between output data of the program and basic modeling in PATRAN.

This study analyze the policy efficiency of the environment-friendly farming zone program using data envelopment analysis. On analyzed results, the average policy efficiency is 0.185 and 98.3% of zones are inefficient. 97.8% of zones are in increasing returns to scales. The empirical results indicate that more work need to be done to increase the efficiency of the program.

In this study, we investigated the methods of using the Cabri3D program for education of problem solving in school mathematics. Cabri3D is the program that can represent 3-dimensional figures and explore these in dynamic method. By using this program, we can see mathematical relations in space or mathematical properties in 3-dimensional figures vidually. We conducted classroom activity exploring Cabri3D with 15 pre-service leachers in 2006. In this process, we collected practical examples that can assist four stages of problem solving. Through the analysis of these examples, we concluded that Cabri3D is useful instrument to enhance problem solving ability and suggested it's educational usage as follows. In the stage of understanding the problem, it can be used to serve visual understanding and intuitive belief on the meaning of the problem, mathematical relations or properties in 3-dimensional figures. In the stage of devising a plan, it can be used to extend students's 2-dimensional thinking to 3-dimensional thinking by analogy. In the stage of carrying out the plan, it can be used to help the process to lead deductive thinking. In the stage of looking back at the work, it can be used to assist the process applying present work's result or method to another problem, checking the work, new problem posing.

In the work of contemporary spatialization, the meaning of program is being an important conceptual element beyond simple functional dimension. The design of this diagram allows to balance among changing programs, and it comes into the spotlight as a medium, which links the virtual to the reality as embodying the virtual, which is not embodied realistically, realistically through the design process. In other words, this method is attracting the public attention as a design tool which can concentrate on design process rather than a fixed tool. This study focuses on the role of balancing among mixed programs and the diagram as a design tool. Therefore, the purpose of this study is to analyze and research the work of spatialization, which apply to diagrams of contemporary designers, is to identify operating mechanism and then is to examine the characteristics and importance of them.

A computer program to calculate properties of nitrogen is developed. Procedures for the calculation is briefly discussed. The program calculates unknown thermodynamic properties fixing the state with two independent input properties. If input value by user is inappropriate, it displays an error message and replaces the input value with an appropriate one. In addition user can change units with easy. The program developed in this work can be utilized to calculate parameters required for the simulation and design of an equipment using nitrogen.
