Objective : There are some advantages of trigeminal evoked potential(TEP) recording compared to other somatosensory evoked potential(SSEP) recordings. The trigeminal sensory pathway has a pure sensory nerve branch, a broader receptive field in cerebral cortex, and a shorter pathway. Despite these advantages, there is little agreement as to what constitutes a normal response and what wave forms truly characterize the intraoperative TEP. This study presents the normative data of TEP recorded on the epidural surface of the rat with a platinum ball electrode. Materials & Methods : Under general anesthesia with urethane, the adult Sprague-Dawley male rats(300-350g) were given electrical stimulation with two stainless steel electrodes which were inserted into the subcutaneous layer of the area around whiskers. A reference electrode was positioned in the temporalis muscle ipsilateral to the recording site. Results : TEPs were recorded in the Par I area of somatosensory cortex and recorded most apparently on the point of 2mm posterior from the bregma and 6mm lateral from the midline. The typical wave form consisted of 5 peaks (N1-P1-N2-P2-N3 according to emerging order, upward negativity). Each latency to corresponding peaks was not influenced by the different intensities of stimulation, especially from 1 to 5mA. Average latencies of 5 peaks were in the following order ; 7.7, 11.1, 15, 22.3, 29.4ms. There was also no significant difference between latencies before and after administration of muscle relaxant(pancuronium). For the electrophysiological localization of recorded waves, the action potential of a single unit was recorded with glass microelectrode(filled with 2M NaCl, $3-5M{\Omega}$) in the thalamus of rat. A sharp wave was recorded in the VPM nucleus, in which the latency was shorter than that of N1. This suggests that all 5 peaks were generated by neural activities in the suprathalamic pathway. Conclusion : In terms of recording near-field potentials, our data also suggests that TEP in the rat may be superior to other SSEPs. In overall, these results may afford normative data for the studies of supratentorial lesions such as hydrocephalus or cerebral ischemia which can have an influence on near-field potentials.

The purpose of the study is to suggest contents, and a range of a Nonnative Theory and a practice for overcoming a crisis of the Mass media. In order to achieve the purpose of the study, a limitation and implication of Social Responsibility Theory was looked into by investigating a Hutchins Report. Hutchins Report suggested the related points at moral duty and legal obligation in implementing mass media's Social Responsibility and Accountability, with relations in publics and community. However, within a view point of a lack of Accountability, Social Responsibility Theory limited responsibility to the realm of 'function', 'self-regulation' and 'self-ethics', In order to promote mass media's quality and serve to rehabilitate its reliability under the pluralistic media system, the contents of Social Responsibility and its scope should be suggested. Media Accountability is a starting point to draw out the contents and scope of Social Responsibility and also a valid democratic plan for mass media to 'social self-regulation' through the mutual communication with civil society. For future Social Responsibility and Media Accountability that is suitable for various mass media, and contents and a range should be defined.

This paper is to provide some suggestions to complement and extend theory of network city, and to consider preliminarily its applicability for development of the Yeongnam region, exploring its normative implications for urban and regional policy and its significance of empirical research. In order to resolve some limitations and problems of network city theory and of empirical research, we need to reconsider systematically analysis methods, to extend indices of connectivity, to reconfirm normative characters inherent in network city theory, to suggest the constitution of cooperative governance, and to develop policies for embedding functional connectivity into internal community. In a preliminary analysis of Yeongnam region on the basis of network city theory, it is not clear whether the urban system of the region is entirely a type of network city, even though it seems to be close to network city. However, in order for the Yeongnam region to orient towards network city, we can point out importance of policy issues such as expansion of transportation and communication infrastructure, strengthening of economic connectivity, constitution of cooperative governance, and local embeddedness of functional network within the region.

Cooperative associations are established in order to enhance the rights and the interests of their members and serve the local communities, and actually do much for the local society. And among these, consumer cooperatives are spontaneously founded, particularly in the spirit of mutual help, in order to promote the common welfare of the members. Meanwhile, because the current medical law qualifys noncommercial corporation to open medical institution, consumer cooperative and noncommercial- corporation cooperative which are established under the Cooperative Act have the right to do. However, though cooperative association should be founded for common interests of the members who are weaker parties of society, it became rapidly to be abused as means of circumvention of law. Especially as National Health Insurance Corporation stepped up the investigation and the collection of unfair profits against the hospital owned by non-medical personnel who are unable to establish a medical institution, setting up medical institutions as a roundabout way to avoid the restricts dramatically increased in number. In this study, we are going to introduce the current dualised normative system regulating the establishment of a medical cooperative association, and find a way to improve the system and make up for the week points. And we will look though the present situation about medical cooperative association's opening, operating, and closing, and review the normative and systematic improving plans.

Contemporary space design has based on the framework of academic standards on a number of scientific propositions in order to find out correlation of human and environment and closely examine approaches of a normative design. However the contents are enormous and introductory and have limitation of application to practical business affairs so that we will have to understand them as a thinking to explain the design with,. Therefore this study is an experimental research making use of concrete design approaches applicable to the area of space design ad cinematic construction as a medium. The purpose and significance of it lies in examining its validity and contributing to the future development of space design. Accordingly this study conducted the research through a literature survey for the understanding of space perception in the cinema deduced the language of design concept according to it examined the basic unit of cinematic construction then analyzed the cases of practical architectural spaces. The findings of this study indicate that human's perception to space and the cinema is deduced as a common conceptual language characterized by the ideas of articulation scenery and timeness. These concepts are very organic and interdependent and can probably become a means for human to appropriately analyze an behavior attribute type of investigating environment with. Also in composing space the basic units of cinematic construction can be as instrument to be easily applied to practical affairs as they are correlated with the function of space and a constituent language to be reasonably designed.

This study identifies the effects of the perceived risk by adolescents on fashion brand conformity for peer groups. Perceived risk, self-esteem, and gender were adopted as variables in order to analyze conformable fashion brand behavior with peer group consideration. A quantitative survey used 672 questionnaires from male and female students between the ages of 14 and 18. The data were analyzed using factor analysis and regression analysis. The results are as follows. First, the dimensions of the brand conformity and perceived risk were revealed. The brand conformity dimensions were normative, informational, and identificational conformity. The perceived risk dimensions were socio-psychological, economic, exchange-refund, performance, management, and fashion risks. Second, fashion (+) and performance (-) risk significantly affected three types of brand conformity. In addition, socio-psychological and economic risk positively affected informational brand conformity. Third, there were more factors of perceived risk that affected brand conformity in the highly self-esteemed group and in the female adolescent group.

Setting a Problem : Developing industrialization and urbanization has been accompanying the outflow of farming-and fisheries village's population, and brings upon lowering of number of fishermen and their productive efficiency as a result. The point of issue of such an outflow of fishermen which is a cause of the shortage of fisheries man-power should be considered through the analysis of the present state of fishery, and then 'How should the normative fisheries man-power policy be performed?' has to be thought after the investigation upon self-existable fishermen's successor-cultivation(SFSC) project which has been driven forward by government. Method of Study : In order to seek concretely a rational way to achieve SFSC undertaking successfully, the teleological method is adopted fundamentally. But the analysis on the fisheries present state centering on fisheries population and the fishery-orientedness of fishermen who are selected randomly in five islands of Jeonranamdo-Province and Kyeongsangnamdo-Province has been tried with the object of groping for a successful and purposive way of successor-cultivation. And the controversial point is brought out through the analysis of the first year's result which SFSC project has been undertaken in 1981. The above-mentioned affair is especially studied on the basic attitude which 'fishery' is a 'profession'.

Objective:The aims of this study are to understand the effects of task (pushing, pulling, and clockwise and counter clockwise twisting) direction on the maximal output and their grip forces and to explore the relationship between the maximal output and the grip forces. Background: Knowing the normative maximal grip force is not enough to design a good hand tool. The industrial designers should understand the required grip forces in various motions toward a specific direction to make an effective and efficient hand tool. Method: Eighteen healthy volunteers participated in the series of isometric maximal output force tests. A custom-made force measuring equipment collected the output and the grip forces for three seconds. Force measurements along the vertical, coronal and sagittal axes were randomly repeated three times. Results: The pulling was strongest and the pushing was weakest in all directions. The effect of motion on the output forces varied in different directions. The corresponding grip force increased in the order of pushing, pulling, clockwise twisting, and counter clockwise twisting in all directions. The maximal output and their grip forces were highly correlated but the relationship was affected by motion and direction. The regression coefficient was greatest in pulling and smallest in clockwise twisting. Conclusion: The effect of motion on the output forces varied in different directions. The maximal output and their grip forces were correlated but the relationship was affected by motion and direction. Application: Findings of this study can be valuable information for industrial designers to develop more productive hand tools and work stations to help preventing the musculoskeletal disorders at work.
