Electromyographic (EMG) signals have been widely used as motion commands of prosthetic arms. Although EMG signals contain meaningful information including the movement intentions of human body, it is difficult to predict the subject's motion by analyzing EMG signals in real-time due to the difficulties in extracting motion information from the signals including a lot of noises inherently. In this paper, four Ag/AgCl electrodes are placed on the surface of the subject's major muscles which are in charge of four upper arm movements (wrist flexion, wrist extension, ulnar deviation, finger flexion) to measure EMG signals corresponding to the movements. The measured signals are sampled using DAQ module and clustered sequentially. The Fuzzy C-Means (FCMs) method calculates the center values of the clustered data group. The fuzzy system designed to detect the upper arm movement intention utilizing the center values as input signals shows about 90% success in classifying the movement intentions.

Recently, the subject of reliability attracts a great deal of domestic and international attentions and the extensive research activities are being conducted as well. Such trend exists mainly due to the fact that the research on the subject of reliability not only contributes to the theoretical developments, but also may find a wide range of applications in practice over several fields. In particular, the research regarding the maintenance policy incorporating certain types of warranty for repairable system and its application is being performed extensively by many researchers, and their efforts seem more concentrated on developing new maintenance policies which minimize the expected operating cost incurred for replacement and repair of the system, while keeping the system at high reliability. Effective maintenance policy may reduce the operating cost and decrease the downtime of the system during its mission period and consequently, increase the productivity of the system. In this article, the major areas of interest in the field of reliability and its historic perspectives are given briefly and the theoretical aspects in several fields of reliability including the maintenance and warranty policies is also discussed. Furthermore, the current domestic situation regarding the education and research on reliability is presented, along with the importance of reliability theory and the difficulty of training reliability personnel. Finally, the author's opinion for effective education system is proposed.

This paper deals with inter-relationship change of women's university students on the process of SW development project using social collaboration tool. Inter-relationship is one of the basic vocational competency in NCS(National Competency Standards) of Korea. We redesigned the curriculum of "Software Engineering" subject for this study and composed the project teams of students to develop software. The details of inter-relationship are satisfaction, communication, faith, friendliness, sensitivity, openness and consideration. From the result of this study, faith, openness and consideration have positive effect but satisfaction, communication, friendliness and sensitivity have no meaningful effect. The surveys were conducted in the beginning of semester and the same surveys were conducted again in the end of semester. The results were verified by paired t-test with SPSS 18.0. It is significant that the using of social collaboration tool for team project has positive effect on inter-relationship change, especially faith of women's university students. This study has some limitations for generalization but has meaning as new trial to enlarge the basic vocational competency of students in major subject, "Software Engineering". We expect new study for inter-relationship change of students to evaluate generality based on the proposed method in this paper.

The purpose of this study is to look for the tendency of 391 Masters' theses(among total 405 theses), which were conferred from graduate school in interior design from 1993 to 1999. This study has been developed by two steps. First step is to select factors such as conferment year, graduate school, field and subject and space of study. Second step is to extract the characteristics of five factors and their interrelations during seven years. The conclusion could be summarized as follows; In the early years, interior design studies were chiefly made by a new schools. And these studies tended to carry out design projects which were connected with residential, commercial and exhibition space. Space design was an absolutely major subject and field of study. But gradually, by many graduate schools, interior design studies have been developed both in quality and in quantity. Various spaces and various subjects were included with design-oriented theories. It was very natural that the character of study depended upon the graduate school. In the future, interior design study had better add some related designs and theories to support it.

We define mathematical learning as a process of overcoming framing difference of teachers and students, two main subjects in a mathematics class. We have reached this definition to the effect that we can grasp a mathematical classroom per so and understand students' mathematical learning in the context. We could clearly understand the process in which the framing differences are overcome by analyzing mutual negotiation of informants in specific cultural models, both in its form as well as in its meaning. We review both of the direct and indirect forms of negotiation while keeping track of 'evolution of subject' in terms of content of negotiation. More specifically, we discuss direct negotiation briefly and review indirect negotiation from three distinct themes of (1) argument structure, (2) revoicing, and (3) development patterns and narrative structure of proof. In addition, we describe the content of negotiation under the title of 'Evolution of Subject.' We found that major modes of mutual negotiation are inter-reference and appropriation while the product of continued negotiation is inter-resemblance.

EIA should be regarded as an aid to improve the decision making processes because it seeks public opinion and external knowledge in order to ensure the maximum degree of fairness and balance in the final decision as much as possible. According to the above benefits, various decision making systems containing EIA concepts were developed in the area of ground water, traffic, disaster or accident and environment in Cheju Island. But because the development of various decision making systems can be the cause of new impact, it was studied the cause and impact of their development. The major reasons for developing the various decision making system like EIA are the lack of the consideration for the impact of project when it is selected project fulfilling EIA and the increase of the effort for the improvement in the professional quality for one subject without the comprehensive assessment among the subject related to environmental impacts. And the development of the various decision making systems like EIA has caused the several impacts like cost elavoration, the relay of project period, etc. Therefore, after it is improved the problems of present EIA on the comprehensive assessment, the various decision making systems like EIA should be integrated in EIA decision making system.
