  • The objective of this research work is to investigate into characteristics of bending stiffness and failure for the ISB ultra-lightweight panel with internally structured material. The expanded metal with a pyramid shape and woven metal are employed as an internally structured material. In order to investigate the characteristics, the specific stiffness and failure map are estimated using the results of three-points bending test. From the results of the experiment, the influence of design parameters of ISB panel on the specific stiffness and failure mode has been found. In addition, it has been shown that ISB panel with expanded metal is prefer to that with woven metal from the view point of optimal design for ISB panel.

  • The objective of this study is to identify the current state of usage and needs for Smart Technology (ST) in the elderly care facilities based on the point of view of staff members. Using survey via mails, data were analyzed with responses from top- or middle-level staff members working in 171 elderly care facilities located in Seoul, Gyeonggi-do, and Chungcheongnam-do. Results indicated that the most needed smart technology was home automation, followed by nurse call system and health monitoring. The technology with the highest feasibility was health monitoring, followed by nurse call system and video phone. Staff members in higher positions working in the elderly care facilities had the highest expectation in improving the image of their facilities by using ST, while they had low expectation for the fact that ST may increase the locus of control of the elderly. This study implies that ST implementations may vary depending on the level of responsibility of staff members and ST how people responsible for the elderly care facilities subjectively perceive the ST.

  • Purpose - Taxes are a critical source of government revenue, particularly for aiding development and progress in a society. Today, taxes are viewed as a tool for growth and stability and for reducing inequalities; a country's citizens play a vital role in realizing this objective through their participation. Research design, data, and methodology - In Iran, tax collection and preparation are always of great concern and represent the most important responsibilities of the government. This study seeks to investigate the administrative barriers in taxpayer participation and highlights the challenges regarding timely tax collection faced during 2011, from the point of view of both tax expertsand taxpayers. Results - Sixty-six questionnaires from taxpayers and tax experts in the Zanjan province were collected and tested using statistical tools. Conclusions - The results indicate that there are no obstacles in taxpayer participation; moreover, both taxpayers and tax experts have similar opinions regarding this issue.

  • The objective of this paper is to develop the new robust and adaptive control system against external environments as applying the probabilistic recognition which is one of the inherent properties of immune system, ability of learning and memorization, and regulation theory of immune network to the system under engineering point of view. In this paper, HIA(Humoral Immune Algorithm) PID controller using Neural Network Identifier was proposed to drive the autonomous guided vehicle(AGV) more effectively. To verify the performance of the proposed HIA PID controller, some experiments for the control of steering and speed of that AGV are performed.

  • As time goes by, men think that their apparence which may be evaluated by someone is a very important thing. The objective of this study is to compare and analyze the data of ideal and real body size which are obtained from male university students. Also, in order to find the difference of view of point between men and women, some data are obtained from female university students. The data are collected from the five typical parts on body such as height, weight, circumferences of chest, waist, and buttock. The samples for this study are randomly chosen from the universities in Seoul and Kangnung during three months (2001. 10~2001. 12). Many researches have reported that there is a strong relationship between cloth and appearance. So far, there are many researches on the body size of females but it is not same for males. The result of this study will play an important role not only for clothing marketing but also for clothing design of men.

  • In a distributed real-time control system, it is essential to confirm the timing behavior of all tasks because these tasks of each real-time controller have to finish their processes within the specified time intervals called a deadline. In order to satisfy this objective, the timing analysis of a distributed real-time system such as shcedulability test must be performed during the system design phase. In this study, a simple application of CAN fur a vehicle body network system is formulated to apply to a holistic scheduling analysis, and the worst-case execution time (WCET) and the worst-case end-to-end response time (WCRT) are evaluated in the point of holistic system view.

  • This paper deals with the optimum cost design of partially prestressed concrete I crosssectioned beams by using Genetic Algorithms. For this purpose, the optimum cost design of two selected example problems that have different characteristics in behavior are performed via Genetic Algorithms by determining their objective functions, design variables and constraints. The results obtained from the technical literature are compared with the ones obtained from this study. The interpretation of the results show that the design of partially prestressed concrete I crossectioned beams from cost point of view by using Genetic Algorithms is 35~50 % more economical than the traditional ones (technical literature) without conceding safety.

  • Purpose: The occurrence ranks of failure modes can come from the real failure but the severity ranks of failure modes require a highly subjective point of view of users. The severity ranks have to find more objective and scientific values. Methods: We found the optimal values by using the correlation analysis between failure mode effects and the criticality number like RPN (Risk Priority Number) in RCM. Result: This paper shows the result that verified whether the weighted values on each failure effect in criticality number calculation is suitable to the actual failures or not. To get the verification, it used the 5 year data and correlation analysis. Based on the analyzed result, We proposed the more suitable values. Conclusion: This correlation analysis approach can provide guidance of RCM analysis across many industries and situations.

  • The soundproof barrier used to reduce the traffic and rail noise is usually designed to the point of view of the acoustic performance such as absorption ratio and transmission loss. But, because the surface of soundproof barrier is polluted by the air pollutant or discharge gas of automobiles, so it's surface cleary maintained by the periodic washing with detergent. But in this case the environmental pollution and the working expenses are worried. So, the objective of this study is to develope the soundproof panel with the self-cleaning properties only by raining.
