The knowledge of the specialized fields has been changed rapidly in the both side of quantity and quality. A hyper media as a knowledge based system is so fixed in the linked media in mutual that we couldn't tell it information provision with the view of user. In this paper, we propose the way of offering intellectual and flexible information which is same with demand in the side of user, selecting, searching and composing the hypertext at the point of user's view through the design of knowledge media system. three concepts is used in order to challenge the knowledge media system : special document, agent system and ontology. The special document is a knowledge using special fields. The agent system is a homogeneous controller that operates on and application to ensure that its activities are coordinated with those of the others within the community, providing a uniform control mechanism. The last 3th concept, ontology is a language for knowledgement, which is a message exchanged among agents to ensure the proper interaction among them. The combination of these three concepts is used designed the prototype of knowledge media system.

In this paper, we develop an intelligent digital redesign method for fuzzy-model-based controllers, effective for tracking control of nonlinear system which may also contain uncertainties. TS fuzzy model is adopted for fuzzy modeling of uncertain nonlinear systems. An extended parallel distributed compensation technique is then used to design a fuzzy-model-based controller for both stabilization and tracking. The designed continuous-time controller is then converted to an equivalent discrete-time controller by using an integrated intelligent digital redesign method.. TS fuzzy model for the representative a single link flexible joint robot system is constructed for the first time, and is used as an illustrative example to show the effectiveness and the feasibility of the developed design method.

The purpose of this study vacs to investigate the relationship between communication and group cohesion in high school baseball team. How the communication-related factors such as an athlete's communication with director, coaches, and other athletes, individual feedback organizational socialization, and the level of information influence the cohesion based factors like individual and goup centered socially oriented cohesion{ individual and goup centered task oriented cohesion was examined in this study. 251 high school baseball athletes registered in Seoul and Kyonggi-Do participated in this study, and self-assessment was adapted in the survey, The collected data were analyzed with one-way ANOVA, Correlation, and Multiple Regression Analysis. The results of the study are as follow; First, it was revealed that the relationship between individual feedback and communication with peers was significant. Communication with peers according to positions was analyzed significant. However, the relationship between communication with the director according to the level of game participation and the level of information was insignificant. Secondly, in the analysis of the relationship between individual characteristics and group cohesion, individual centered task oriented cohesion differ from position to position, In addition, all the independent variables have significant relationships with the level of game participation. Thirdly, positive relationships were come out significant between individual feedback and individual centered task oriented cohesion, between communication with the coach and group cohesion, individual and goup centered task oriented choesion and group centered socially oriented cohesion between communication with peers and group cnetered taks oriented sochesion and individual centered socially oriented choesion. However, it was revealed that the relationship between the level of information and group and indivisual cohesion were insignificant.

In the system using one sensor, to describe accurate situation or conclude from information of one source in difficult. Moreover, sensor noise degrades the belief of decision. Multisensor information system, however, can increase the belief of date by imploying more than one source of information simultaneously. Another advantage of the system is that it can accomplish its task with other sources of information when one source malfunctions. In this paper, we implemented data association methods to identity moving flight targets using distance, probability theory, Dempster-Shafter theory for the low level process in the information fusion system. Data association is to classify information from various sources into data groups depending for the same flight object. Times and errors of these data association methods are analyzed.

In this paper, describe the magnetic sensor detecting the speed of wire or thin pipe, which move irregularly, using Hysteresis phenomenon. After magnetic field is placed to a metallic object, this magnetic sensor converts residual magnetism into velocity, This magnetic sensor is composed of transmission part that causes magnetism, reception part that detects magnetism, and control part that convert magnetic field intensity into velocity.

천연고무/부타디엔고무(NR/BR)혼합고무와 황동피복코드의 접착성질

천연고무(NR고무)와 부타디엔고무(BR고무)의 혼합고무에 대한 물성과 황동피복코드의 접착성질을 조사하였다. BR고무 혼합량이 많아지면 가황된 사슬의 끊어짐(reversion)이 억제되어 가교밀도가 커진다. 이에 따라 영률은 증가되나 파열점에서 측정되는 인장강도와 연신율은 파열에너지 저하로 낮아진다. 접착시편에서 높은 고무부착정도는 접착계면 강도가 고무층에 비해 상대적으로 크다는 것을 보여준다. BR고무가 증가함에 따라 뽑는 힘이 감소한다. 뽑는 힘과 혼합고무의 인장강도의 좋은 상관성은 뽑는 힘이 혼합고무의 피로성질에 주로 관련이 있음을 나타낸다. 황동피복코드와 접착에 대한 NR고무와 BR고무간 상호작용은 나나지 않았다. Physical properties and adhesion characteristics of blended rubber compounds composed of natural rubber(NR) and butadiene rubber(BR) were investigated. With increasing BR content, crosslinking density was increased due tn the inhibition of reversion. As a result, Young's modulus was increased, while tensile strength and elongation measured at break point was decreased due to the decrease of tear energy. High values of rubber coverage of these adhesion test samples showed that the strength of adhesion interface was relatively higher than that of rubber layer. Pullout forces decreased with increase in the BR content. A good relationship between pullout force and tensile strength of the blend is observed, indicating that pullout force is mainly dependent on the fatigue properties of the blend. Interaction between NR and BR in the blended rubber compounds for the adhesion with brass-plated steel cord was not observed.

Various clinical and histopathologic characteristics are currently used to obtain prognostic information about cervical carcinoma, but they do not predict the outcome for any individual patients. Thus, there is a need to identify additional tumor characteristics that are able to predict more accurately the outcome for an individual patient with cervical cancer. In this study, we explored the relationship between cathepsin-D expression and progression of the cervical neoplasia, the correlation between response to neoadjuvant chemotherapy and cathepsin-D expression, and we investigated if tumor cell cathepsin-D expression could serve as a prognostic factor in cervical carcinoma. Tumor tissues were obtained from 14 patients with cervical intraepithelial neoplasia and 52 patients with squamous cell carcinoma of the cervix. Cathepsin-S expression was identified by immunohistochemical methods using monoclonal antibody cathepsin-D (BioGene). Positive cathepsin-D immunoreaction in greater than 30% of carcinoma cells was scored as high expression. High cathepsin-D expression was seen in 15 of 52 invasive cancer but was absent in cervical intraepithelial neoplasia. It was shown that cathepsin-D expression was independent of the rumor grade, tumor size, lymph node involvement, depth of invasion, parametrial invasion, and response to chemotherapy. In disease free survival analysis by log-rank test, cathepsin-D expression was not significantly associated with survival. These results show that cathepsin-D expression is not a clinically useful adjunct to assessment of prognosis in invasive squamous cell carcinoma of the cervix.
