This paper deals with the efficient planning of robot motions in the Cartesian space while avoiding the collision with obstacles. The motion planning problem is to find a path from the specified starting robot configuration that avoids collision with a known set of stationary obstacles. A simple and efficient algorithm was developed using "Backward" approach to solve this problem. The computational result was satisfactory enough to real problems. problems.

The family disaggregation model of hierarchical production planning (HPP) is the problem of (0 -1) mixed integer programming that minimizes the total sum of setup costs and inventory holding costs over the planning horizon. This problem is hard in a practical sense since optimal solution algorithms have failed to solve it within reasonable computation times. Thus effective familoy disaggregation algorithm should be developed for HPP. The family disaggregation algorithm developed in this paper consists of the first stage of finding initial solutions and the second stage of improving initial solutions. Some experimental results are given to verify the effectiveness of developed disaggregation algorithm.

This study deals with roughing planning by cross sectional information generated from sculptured surfaces. Bicubic Bezier surface is adopted as sculptured surfaces in this paper. The system consists of 3 pstyd : 1) modeling sculptured surface, 2) reconstruction of cross-section in 2D coordinates, 3) determination of roughing tool path with structural data. The system is developed by using BIM-PC in the environment of Auto CAD R11, AutoLISP and MetaWare C. The proposed system shows an efficient algorithm for roughing planning with cross sectional information.

The purpose of this study was to establish the basic concept on the creative and better family life planning. This planning afford promise of implement about the family life tasks and preventive interventions of family life problems or issues. The conceptual forcus are on the values, interdependence, wholeness, adaptation and balance of human life. This study provide of the basic about the social education program and family life education for quality of life.

This study is resource planning of painting lines in Korean motor company using simulation techniques. The painting lines have bottle neck problems that is considered production capacity, number of lines and so on. The alternative solutions is decided by the result of simulation techniques. This Paper is focused on resource planning using simulation techniques.

In this modern environment, manufacturing companies must continually persevere in their efforts to solve the problems encountered in the effort to improve productivity and quality while simultaneously reducing production costs. In this paper, we have approached the problem of layout planning by using the Muther' Systematic Layout Planning model (1961). This model applied the "H" company layout problem. In conclusion the "H" company mislayout in plant. We have a compare this model to old method ("H" company present layout), we produced a good result in layout.

As abnormal climate phenomena occur more frequently due to climate change, damage which results from meteorological disaster increases accordingly and its scale and variety are becoming wider. This paper draws out planning and design elements and application techniques to build cities more adaptive to climate change from urban development cases in US and Europe. An urban model is suggested, that enables built environment to be more resilient to risks caused by climate change is applicable to urban development projects in practice.

Background: Family planning is widely practiced today to resolve the over-growing population and overcome obstacles that thwart socio-economic growth. While Ghana was the first country in Africa to implement family planning program, its birthrate is still twice as much as world average due to weak infrastructure and strategic plans to enforce the policy. Thus, there is a need to objectively verify the factors that affect family planning of fertile women of Ghana. Methods: Total of 630 self-administered questionnaires were distributed from April 8 to 17 of 2013 to collect data. Six-hundred eighteen questionnaires were analyzed, excluding the 12 incomplete questionnaires. Collected data were analyzed using PASW SPSS ver. 18, and logistic regression analysis was performed to verify the factors that affect practice of family planning. Results: Satisfaction with health and medical facilities, experience with family planning education and awareness of birth control methods significantly affected practice of family planning. Based on analysis using odds ratio, enforcement rate of family planning increased by 4.574 times when the subjects were satisfied with health and medical facilities, by 3.920 times when received family planning education, and by 3.284 times when they were aware of birth control methods. Conclusion: By adopting family planning education program, government should be able to change fertile women's perception of family planning. A strategic plan is necessary in order to increase access to medical facilities, improve service satisfaction, and induce women to enforce family planning voluntarily.

The purpose of this study were to develop a financial management educational program for college students and to evaluate the effect of this program. In order to achieve this aims, a fundamental work to select the educational contents was preceded with a survey of learners' needs, preceding studies. After choice of educational contents, learners' demands on how to manage the educational program was executed in advance. The participants in this study were 500 students, resulting in 460 with usable data. Second, reflection the above mentioned educational contents, a concrete financial management educational program was built. This program consists of 9 domains: financial planning, careers and income, consumer spending, credit use and Credit cards, Managing Taxes, investment planning, risk management and insurance, retirement and estate planning, contribution. The participants for this program implementation were 68 students. Third, to evaluate the effects of the financial management educational program, paired t-test was conducted in using the SPSS package. The result suggested that financial management educational program has a positive effect on financial knowledge, financial attitude and financial management behavior. Several implications based on the findings were suggested.

This study was carried out to figure out the relationship between EAmaturity, information management capacity, and information performance, and find the effect between these variables and the reciprocal causation. The study found that EAmaturity has a positive effect on information resource management and performance. In other words, the effect of input, calculation, management and utilization factors on information planning in EAmaturity showed that calculation, management and utilization factors have a significant effect on the information planning. While the effect of input, calculation, management and utilization factors on information introduction and management showed that only both calculation and utilization have a significant effect on the information management factor. It says that EAinput in EAmaturity does not play a big part in the planning stage, as well as not go through a series of process that is connected to the maturity stage by immediate field application. Consequently, EAmaturity varies from the level that EAcreates introduction and performance according to organization. This suggests that the maturity and performance can be also changed by the level that EAcreates information performance by accepting and using this capability within organization as well as the capability to introduce and fully perform the EAsystem presented in enterprise architecture framework of public sector.
