The process design of forward Extrusion and Upsetting of Axi-symmetric part has been studied in this paper. During the cold forging product; auto transmission Solenoid Valve part, the defects such as folding and under-fill can be appeared by the improperly controlled metal flow. In this study, to reduce the folding and under-fill the design of experiments has been used to find out the significant design variables in the design of forging process. This paper deals with an Process Planning with which designer can determine operation sequences even after only a little experience in Process Planning of Multi-Former products by multi-stage former working. The approach is based on knowledge-based rules, and a process knowledge-base consisting of design rules is built. Based on the systematic procedure of process sequence design, the forming operation of cold forged auto transmission Solenoid Valve part is analyzed by the commercial Finite Element program, DEFORM/2D.

The railway route and alignment planning have been executed with a limited number of alternatives based on the site pre-survey and the topographic map. This study developed an intelligent railway alignment planning program (ei-Rail) which can derive all the considerable design alternatives and provide the data for the alternative evaluation such as constructions cost, operation cost, and etc. According to the comparisons with prevailing planned railway projects, the time and cost for planning can be reduced as well as the construction costs. This program may contribute to the development of railway industry by reducing the time and cost for planning as well as the total project cost.

Purpose: This study was to investigate the effects of career education program on career self-efficacy, career adaptability and career stress among nursing student. Methods: A one-group, pre-post design was utilized with 95 nursing students as subjects. The career education program was consisted of four domains((1) Career exploration, (2) Self understanding, (3) Establishment of career planning (4) Practice of career planning) and included counselling, special lectures, simulated job interview, and feedback of interview. The data were analyzed using descriptive statistics, paired t-tests, ANCOVA(SPSS 20.0). Results: The scores on the factors of career self-efficacy(t=4.48, p<.011) and career adaptability(t=3.02, p=.003) increased significantly after the education intervention. The score of career stress(t=-2.45, p=.015) decreased significantly. Career education program is useful in improving career self-efficacy, career adaptability and career stress in nursing students. Conclusions: The results of study suggest that there needs more development and application of career education program.

This study is about the ‘paradigm’ which works as a theoretical base for planning and managing elderly housing. For this purpose, this study surveyed published research works, and analysed the contents and the paradigms of the researches. This is based on the literature survey, and surveyed 66 research works published in the last 8 years. The result of the survey tells us that almost all of the research works done by Korean scholars are based on the rational approach to the design of elderly housing. They emphasize ‘functional rationalism’ ‘technical perfection’ ‘reasonable program’ ‘economy and market’, etc. However, such qualities as‘character of human being’ ‘depth of existence’ ‘identity of culture’ ‘speciality of place’are not emphasized. This means that paradigms used by Korean scholars are biased, and are far from the plural culture characterizing 21 st century. This study, therefore, analysed new paradigms appeared on the recent research works about housing environment, and suggests several new paradigms which would be essential for future planning of elderly housing.

Presented in this paper is a procedure of developing graphical simulation software for planning robot welding processes. Welding is by far the highest application area for industrial robots, and it has been in great need of such a simulator in designing robot work cells, in justifying the economics of robot welding and in planning robotized welding operations. The model of a robot welding cell consists of four components: They are an welding structure which is a collection of plates to be welded, a positioner to hold the welding structure, a robot with a weld torch, and a set of welding lines (in case of arc welding). Welding structure is modeled by using the reference plane concept and is represented as boundary file which is widely used in solid modeling. Robot itself is modeled as a kinematic linkage system. Also included in the model are such technical constraints as weaving patterns and inclination allowances for each weld joint type. An interactive means is provided to input the welding structure and welding lines on a graphics terminal. Upon completion of input, the program displays the welding structure and welding lines and calculates the center of mass which is used in determining positioner configurations. For a given positioner and robot configuration, the welding line segments that can be covered by the robot are identified, enabling to calculate the robot weld ratio and cycle time. The program is written in FORTRAN for a VAX computer with a Tektronix 4114 graphic terminal.

Recently, plans to revitalize rural areas in addition to farming are actively having been groped since given agricultural conditions destituted. One of the plan is the 'Rural Tourism' which to sell to urbanites by merchandising rural and pleasant characteristics possessed by rural areas. As a part of the rural-urban exchange, analyzed the features of the experience programs operated by each village by selecting 152 rural-mountain villages where is supporting and presented results by synthesizing above conclusion. The results acquired through such research are as following. Currently, villages operate mainly with the experience program related to general agricultural life styles by synthesizing special features of experience programs with high frequency in operations as the present status of the rural-mountain villages and showed negative trends dependant to the existing natural resources and easy in operations. Moreover, the operation of the experience which are expected to publicize the village and create large incomes were insufficient, analyzed not to be stimulate purchasing activities by lack of connections among experience programs and only simple staged experiences are mainly operated due to low operation frequency of experience programs which can be operated with special interests or professional characteristics.

This study focused on defining and applying the diagnose scales to the household life in context with the family life planning based on the systems approach. In this study the household life consisted in 4 life subareas, i.e. time use, nonhuman resources(housing and durable goods), household financial and communication/problem solving competence of family members. Data were collected from 1200 full-time housewives who live in Seoul, Kyungki, Chungbuk, Jeonnam and Jeonbuk, Kyungnam and Kyungbuk and have at least 1 child in school age. The results show that the 4 areas of household life are in the level under the diagnose scale totally. The results of this study contribute to the systematic family life planning and the Problem solving of general household life. And the scales that are investigated through this study can be used the self family life diagnose Program.
