This article was trying to suggest an agenda and alternatives of home health care policy for the future home care growth and development and examine the significance of new health care law and regulations. In addition. It was to analyze and drive the home care system problems. of which was made an announcement on the 11th of April. that home health care project must be centered from the nationwide general hospital. As we have learned from the developed countries, the home health care have been closely related health care policy among the field of nursing area. Therefore. we need to understand our national health care policy and need to predict the future direction and goal of our home health care policy in order to enhance the growth and activation of health care system. Additionally. we also need to have a vision and ability to develop under our own health care policy with systematic and rational home care business escaping from past perspective and standpoint. We must create a master plan of home care system to fulfill one part of system of the function and an important role in order to pursue an advanced health care plan under our system. For instance. in the 21th century as we establish a master plan for the growth of our country home care plan with improving plan systematically and also we need to produce many highly qualified researching and good personal who can develop and maintain the system efficiently. Specially. based on the unique characteristics of our health care system and the direction of development of plan, we need to find and correct the problems which we have faced the present time, so that we can provide and reach the goal of advanced health care system which our government want to pursue. Finally. we have to strive our best effort to make our home health care system can be positioned and stand the right direction to have the benefit for every individual citizen in our country.

The purpose of this study was to find effects of hypertext structure and self-direction on learning performance. To reach the goal, we got 69 H highschool students and tested self-direction we treat hypertext program to them. The results found were that hypertext style(non-structure, structure) didn't effect on academic achievement but did effect 1earner's self direction. Also, we found interactive effect of hypertext structure and self-direction on academic achievement. Following studies have limits verified learning effect, because this studies are carried out in short-term research. Further studies need the study of effect of hypertext structure and self-direction on academic achievement for a long-term research. Also, further studies should accomplish the study considering learner characteristics besides self-direction and will need succeeding studies including various learning contents besides computer general curriculum.

Gijang Sea is located on the southeastern coast of Korea. This study establishes a basic system to identify optimal sites for the wave power generation. To achieve this goal, the field measurements were made at the field site in front of Dong-am fishing port at Gijang. In addition, we analyzed the offshore wave data at the Donghae buoy operated by Korea Meteorological Administration(KMA) and compared the data with the wave characteristics in Gijang Sea. The main results were as follows. In winter, the wave direction in Gijang Sea ranged between east and south($90{\sim}180^{\circ}$). The main wave direction was east($90^{\circ}$). The Significant wave heights and periods were under 2 m and $5{\sim}15$ sec, respectively. A comparison of water depth and wave direction constitutes one(condition) of the important parameters for selecting the optimal site for the wave power generation.

This paper aims to develop a practical finite capacity MRP (FCMRP) system based on the needs of an automotive parts manufacturing company in Thailand. The approach includes a linear goal programming model to determine the optimal start time of each operation to minimize the sum of penalty points incurred by exceeding the goals of total earliness, total tardiness, and average flow-time considering the finite capacity of all work centers and precedence of operations. Important factors of the proposed FCMRP system are penalty weights and dispatching rules. Effects of these factors on the performance measures are statistically analyzed based on a real situation of an auto-part factory. Statistical results show that the dispatching rules and penalty weights have significant effects on the performance measures. The proposed FCMRP system offers a good tradeoff between conflicting performance measures and results in the best weighted average performance measures when compared to conventional forward and forward-backward finite capacity scheduling systems.

The scope of the problems that could be solved by monitoring and the improvement of the recognition time is directly correlated to the performance of the management function of the business process. However, the current monitoring process of business activities decides whether to apply warnings or not by assuming a fixed environment and showing expressions based on the design rules. Also, warnings are applied by carrying out the measuring process when the event attribute values are inserted at every point. Therefore, there is a limit for distinguishing the range of occurrence and the level of severity in regard to the new external problems occurring in a complicated environment. Such problems cannot be ed. Also, since it is difficult to expand the range of problems which can be possibly evaluated, it is impossible to evaluate any unexpected situation which could occur in the execution period. In this paper, a process-evaluating model based on the goal scenario is suggested to provide constant services through the current monitoring process in regard to the service demands of the new scenario which occurs outside. The new demands based on the outside situation are analyzed according to the goal scenario for the process activities. Also, by using the meta-heuristic algorithm, a similar process model is found and identified by combining similarity and interrelationship. The process can be stopped in advance or adjusted to the wanted direction.

The most important topic in research of mobile robot is path planning in order to avoid with obstacle. In this study the path planning algorithm using a neural network model is proposed. The inputs of neural network are range data which are acquired form laser range finderm and weights are based on difference with goal direction. The thresholds are made by consdiering the marginal distance between mobile robot and obstacle. Consequently the outputs are obtained by multiplying input and weight. The obtained heading directiion enables the mobile robot to approach the goal, without any collision with obstacles around. The effectiveness of the this method of real-time navigation of a mobile robot is estimated by computer simulation in complex environment.

$SiO_2$ via-hole etching with a high aspect ratio is a key process in fabricating ULSI devices; however, accumulated charge during plasma etching can cause etching stop, micro-loading effects, and charge build-up damage. To alleviate this concern, charge-up damage sensor was fabricated for the ultimate goal of real-time monitoring of accumulated charge. As an effort to reach the ultimate goal, fabricated sensor was used for electrical potential measurements of via holes between two poly-Si electrodes and roughly characterized under various plasma conditions using statistical design of experiment (DOE). The successful identification of potential difference under various plasma conditions not only supports the evidence of potential charge-up damage, but also leads the direction of future study.
