The pre- and post-processor for finite element structural analysis considering the user-friendly device are developed by using GUI. These can be used on WINDOWS' environment which is realized the multi-tasking and the concurrency by object-oriented paradigm. They are designed to control integratedly the pre-processing, execution and the post-processing of the finite element structural analysis program on multiple windows. These object-oriented modeling approach can be used for complex integrated engineering systems.

A method for generation of design verification tests from behavior-level VHDL program is presented. Behavioral VHDL programs contain multiple communicating processes, signal assignment statements. So for large, complex system, it is difficult problem to test or simulation. In this paper, we proposed a new hardware design verification method. For this method generates control flow graph(CFG.) and process modeling graph(PMG) in the given under the testing VHDL program. And this method proved very effective that all the assumed design errors could be detected.

This study is to develope the quantitative risk assessment program for consequence analysis of fire and explosion (PML-Chem), which is applicable to the chemical plants. The advantages of PML-Chem is easy to use and acquire results. Especially, PML-Chem was embedded real weather condition database for major chemical plants in ${\bigcirc}{\bigcirc}$ complex in country. Also, reliability of PML-Chem was verified through comparing PML-Chem with PHAST-Professional which is already commercial.

The practical computer program COL3 was developed through this study to design of arbitrarily shaped reinforced concrete slender columns subjected to combined compression and biaxial bending. The program COL3 has been developed for user-friendly environment using spreadsheets. Several examples including for analysis of geometrically complex column sections subjected biaxial bending are introduced in this paper.

This paper describes the program of optimally choosing parameter in designing inductor, which applied by fuzzy theory, and verifies the reliability of program to use in design of power supply of electronic machine and information communication. It is available to find optimal value of complex and various parameter, such as core, winding, winding number, and air-gap, etc., needed on designing inductor. We expects to minimize time and cost of inductor design.

Railway signal system has been more complex, larger and required high reliability. So, maintenance by experience must be changed to optimize maintenance program or introduced systematic method for estabilish new maintenance program. In this paper, we introduced the maintenance period decision method which are Age based method and Block replacement method based on the failure distribution for the equipment. So, we allocated optimum maintenacne period for the railway signal equipment using block replacement method.

Air pollution problems are serious and present significant challenges to the engineering research community. EPA's engineering research programs have shifted from a primary focus on $SO_2$ and NOx pollution control to more complex and more difficult problems such as indoor air quality, air toxics, and global climate change. EPA research engineers are working closely with other research organizations in both the private sector and other federal research organizations to identify, evaluate, and develop cost-effective engineering solutions. The APPCE works closely with the EPA regulatory and regional offices to ensure that the best engineering information is utilized to formulate and implement the Agency's environmental protection program.

PURPOSE: This study aimed to investigate the effect of complex theraputic exercise on visual analog scale of pain, shoulder' range of motion for middle-aged women with breast cancer related lymphedema. METHODS: The 14 middle-aged women involved voluntary in this study and then they were divided into two groups(n =7 per group). The complex exercise program was implemented over 4 weeks, 60 minutes per day, with 3 types of exercise for stimulation whereas the control group was performed a classical decongestive physiotherapy in a same day. For data analysis, the mean and standard deviation were estimated; 2 way repeated measures ANOVA was carried out. RESULTS: First, The level of VAS was significantly reduced on time, interaction effect in the group. Second, most factors of ROM were significantly increased on time, interaction effect whereas extension was not significantly increased. CONCLUSION: In conclusion, Our results showed that complex therapeutic exercise could improve or maintain VAS and ROM of shoulder joint for middle-aged women with breast cancer related lymphedema.

This study was to verify the effect of complex training programs on the postural balance and trunk muscle strength of the elderly. We recruited 40 elderly participants aged 60 to 75 years. Subjects were evaluated before, and 12 weeks after. The participants underwent complex training programs, including free exercise, elastic band and unstable plate. Exercise were performed as follows: 10 repeats in 50 minutes (0 to 4 weeks), 13 repeats in 50 minutes (5 to 8 weeks), and 15 repeats in 50 minutes (9 to 12 weeks). The training group underwent complex training, including warm up, thrice a week for twelve weeks. The control group did not perform any complex training. Results indicate that the postural balance and trunk muscle strength in the training group significantly increased. Data generated from this study could be applied to develop a complex training program to efficiently build whole body muscle strength.
