HHV-8 virus is known to be associated with Kaposi's sarcoma (KS) in HIV seropositive patients and its seroprevalence has geographic difference, In South Korea, incidence of KS is low not only in general population but also in HIV patients compared to other countries, It is speculated that low seroprevalence of HHV-8 has contributed to the low incidence of KS in South Korea. We examined the seroprevalence of anti HHV-8 IgG of HIV seronegative health care workers in one University hospital. Enzyme-linked immunosorbent assay(ELISA) was used for diagnosis. One person (0.6% 1/164) was seropositive, six were equivocal (3.7%,6/164) and 157 people were seronegative (95.73%, 157/164). This study revealed that seroprevalence of HHV-8 in general population was. low in South Korea. Further studies are needed to be carried out to evaluate the low HHV-8 seroprevalence in Korea.

A. The necessity and purpose of the study Since 1960s the number of university and college students has increased due to the rapid industrial development which requires more technical and intellectual persons. Also the upward spreading effects of education with generalization of secondary education have increased the social demands of liberal education, which expedite university students' diversity and heterogeneity. Therefore, the problems of students are no longer those of school authorities, but expand into social and national problems. Recently most of university in Korea have put more emphasis on the rearrangement and reinforcement of Student Guidance System. Especially, in case of Jeju National University, taking into considerations the special geographical conditions far away from the Korean mainland, and transitional stage on which JNU was promoted to national full-university status, along with the unification of campuses, the more careful interests and efforts are required for student guidance. This study was conducted with a view to providing the opportunities of educational and social specialization of student guidance. The following are the purpose of this study: 1) To set up directions for student guidance which can carry out the role and function of the university. 2) To consider, in the aspect of education, the main factors which influence the problems of university students. 3) To find out the difference between the problems of students' demand and abilty and realities of guidance, by comparing and analyzing present guidance realities between universities. 4) To offer improvement directions for efficient student guidances. B. The scope and contents of the study 1) The problem of student guidance in view of the purpose and function of a university. 2) The fundamental viewpoint of guidance in university 3) A theoretical investigation for efficient student guidance 4) A root cause of student problems 5) The present condition and problems of student guidance 6) Improvement directions for guidance C. The method of the study 1) To analyze the domestic data as well as foreign data 2) To analyze the questionnaire 3) To analyze the results of guidance through the actual result reports of student guidance 4) To analyze various data of student guidance 5) To represent by percentage(%) the realities and problems of student guidance D. The problematic factors of student guidance in the light of purpose and function of a university 1) The original purpose and functions of university are the acquisition of knowledge the transmission of knowledge, and application of knowledge. They are based on the wholemen community of intellectuals in which research, education, and service are determined to be prime mission, but hasn't well been fulfilled because of the present special situations of Korea. 2) In the expectations of university's roles, it is becoming important to harmonize the real desire of administrative officials, intellectual desire of professors, and idealistic of students with each other. 3) A university's research function of creating academic atmosphere is very unsatisfactory. 4) The relationship between professors and students, and even among students hasn't well progressed because of excessive solicitude of omission by graduation quota system as well as full classes. And cultural education is not conducting effectively because it is very fragmentary and formal. 5) The chaos is being produced about the establishment of concept of community service given to university education, the ways and limitations of participation in society and actual world. E. The viewpoint of student guidance The contents and methods of student guidance are decided according to the view of students to be the subject of guidance. In the reformative viewpoint of student guidance by educative instruction methods, main method of guidance are authority, blind obediance, cramming, subjectivity, control, rectification. From the educative viewpoint of student guidance, self-direction can be possible by means of students' interest, desire and ability. Future student guidance must be conducted to develop their potentiality and natural ability of growth without external force or blind gramming. F. Following theoretical investigation were enforced in order to establish effective directions for student guidance. 1) The concept and purpose of the orientation for freshmen and its basic policy and contents 2) The necessity and contents of department arrangement guidance 3) The practice of alloted academic adviser system 4) The educational functions, necessity, and meaning of campus extracurricular activity 5) The role and function of student government(SNDC) 6) The welfare and scholarship system for students G. As a result of a selection of root causes of student problems from the introspection, the following were important order of immediate and expected problems 1405 freshmen; 1. Studies Problem(40.3%) 2. Course problem(36.4%) 3. Economic life problem(36.9%) 4. Social fitness Problem(26.7%) 5. Health Problem(16.0%) The investigation consequence for sophomore and junior are following; 1. A course Problem(35.2%) 2. Economic life problem(35.4%) 3. Human relation problem between professor and student(35.2%), and a good use problem of spare time(35.2%) 4. Studies problem(26.4%) H. The problems were revealed by a statistics which were investigated and analyzed realities of student guidance as follows, respectively: 1. In the orientation for fresh, it is emphatic to give only a information, the program of a important purpose in an orientation that are helpful to initiation of university life with a safety emotionally by withdrawing from strain from strange environment is making light of. 2. In the guidance of a department choice, department allocation by a record is making without giving a chance searching for self-characteristic like aptitude or hobbies, the guidance plan and materials of objectivity are not prepared, and the chance choosing carefully comes very short of. 3. In the management of partial charge professors system, the relation position between professor and student is very formal because, as a matter of fact, it is meaningfulness to guide students from a professor is responsible for guidance of so many students, director of professors are in want of the whole recognition about guidance contents. 4. Though the circle activities are very important as an educational function, a director professors of a circle has charge of guidance for so many students, the activities without purpose consciousness are unfolding, the activities with interest and recreation mainly are rich in, and the activities for enlightenment sound activity model which gets a value experience are situation insufficiency itself. 5. In the activities and management of Student Body, he is not accomplishing plan and function by nature, the activities and management individual and new are very lack owing to emphasis of events centre and actual results centre. And the appearance of making heteronomy now that he is not also chose relation to the circles in SNDC is more and more deepening. 6. The lower organization taking charge of students guidance specially in managent of the students guidance institute are in need, the number of specialists are for want of, it is just so formal to run the students guidance institute because the institute's finance is in very poverty, its originally functions are not accomplishing due to the consultation mood in consultation room is stiff. 7. Our university lacks in research facilities and mental incentive with regard to student welfare function. I. I am directing the way of student guidance for withdrawing from and getting rid of the problems revealing, concerning the students guidance to the best of his ability by the realities of students problems as follows; First, the investigation and research activities and assistance understanding and helping students have to provide in the side of prevention of problems by understanding university students' nature consciousness and characteristic regularly. Second, students' spontaneous participation, the development of interesting and useful programmes, and faculty members' active supports & guidance should be given to obtain effective result of fresh's orientation. Third, school authorities should provide freshmen with opportunity to judge their aptitudes from the time of entrance by holding orientation several times, and by offering detailed informations on the department selection. Fourth, The academic & human relations between professors and students should be maintained through proper enforcement of alloted academic professor system. Fifth, every circle and club should established proper and patent objectivities of activity, and try, to create and introduce useful and interesting programmes in order to promote an educational function of each circle and club. Sixth, in order to eleminate the gap between students and Students Government, students should take deep interests in Student Body's activity, while Student Body should develop academic and literary activity to promote students research activities. Seventh, in order to promote the function of Student Guidance Institute, there should be secured expert staff for smooth counselling, investigation and employment guide as well as financial and administrative support of school authorities. Finally, university authorities should organize several institute such as student welfare committee(institute) so that they might grasp what student opinions & desire are and make students lead comfortable campus lives.

Among the three anomalies related to the IPO market, most of the studies up to now have been focused on the short run underpricing, and studies concerning long run price behavior are insufficient in a way. But outside Korea, a number of studies show that short-selling has more advantage. On the other hand, in Korea studies concerning long run price behavior are lacking and cannot show the characteristic of the IPO with satisfaction. So the following study will try to take a look at long run performance of IPO. Therefore, IPO stocks employed here were from 269 firms, open to the market from 1988. 6. through 1994. 12. The main results of the tests can be summarized as follows. The long-run performance wasn't consistent with worldwide poor aftermarket evidence. On the contrary, the long-run performance produced better return compared with the average market return. Also, In the analysis of the cumulative abnormal returns for 36 months by way of the wealth relative, once used by Ritter, the Korean IPO stocks obtained superior long-run performance unlike in the previous research concerned. In conclusion, buying the IPO in the primary market and selling them in the secondary market seems, on average, to be a good strategy. Investors in Korean IPO market can gain excess return due to underpricing at the offering.

This study confirms the initial and aftermarket's performance of IPO across the information asymmetry, signaling effect in the Korean Stock Market. Performance is measured by market adjusted excess return. Also, to find out what variables can explain that performance, there exist various empirical tests by regressing the firm specific variables. For this purpose, two hypothesis were made concerning the existence and causes of the early abnormal returns of IPO stocks. In June, 1988 when the governmental interference in pricing of IPO share was lifted, the offer price was set through direct negotiation between the issuing firm and underwriter. Yet, even with the adoption of liberalization reform, the high level of excess returns is still observed in the Korean IPO market. Therefore, IPO stocks employed here were from 269 firms, open to the market from 1988. 6.(the liberalization period) through 1994. 12. The main results of the tests can be summarized as follows. First, The positive excess returns were confirmed and the initial day market adjusted return is statistically significant at the level of 55.27%. Second, Using the size of issue and, capital after offering and the life of firms as a proxy of ex-ante uncertainty and the initial abnormal return of IPO. The weighted competition ratio also has a positive relation with the initial abnormal return of IPO. Third, Firms that do not issue equity after their IPO, are less underpriced than otherwise. This result shows that underpricing of IPO signals that the firm is good for investment, because only good firms can recoup the loss after. Also, Initial abnormal return is negatively related to the share fraction of the issuer. In conclusion, buying the IPO in the primary market and selling them in the secondary market seems, on average, to be a good strategy. Investors in Korean IPO market can gain excess return due to underpricing at the offering.

The study is designed to suggest a direction towards creative approaches to space planning by applicable characters of architectural space with the introduction of The Mirror-Metaphor, as an alternative to problems such as the communicative severance, estrangement based on our unconsciously feeling in the architectural space. Here we have to know to the so-called 'The Mirror-Metaphor' concept in 'The Mirror Stage' proposed by Jacques Lacan. The mirror-metaphor is the mediator for connection between the other and me on a first recognition. We can find to expectant effects that a reflection, the whole, the identity in the space design by the application of the mirror-metaphor. It solve to problems on the communicative severance and estrangement phenomenon between a user and the architectural space.

Purpose : The purpose of this study was to analyze the MR findings of intramedullary tumors and review the literatures for evaluating of characteristic findings of each intramedullary tumors. Materials & Methods : We experienced eight intramedullary tumors from March 1993 to February 1995, including four astrocytomas two ependymoma, one hemangioblastoma, and one cavernoma. MR images were get by 1.5T GE Signa and analized retrospectively. Results : Intramedullary tumor was demonstrated by MR images in eight patients. They were five men and three women ranging in age from 3 to 56 years and complained both motor and sensory changes and symptom duration was between 6 months and 3 years. Ependymoma showed diffuse homogenous enhancing mass at the level of thoracic cord(T2-3) and thoracolumbar level(T11-L2) without cystic change, One had hemorrhage within the mass and massive leptomeningeal metastasis at all spinal cord and brain. Among astrocystomas, one case at the cervical cord unusually revealed hemorrhage in the mass and regional large syrinx. The other one occured at the conus medullaris portion and showed well-defined mass and intratumoral cystic change. We also experienced rare intramedullary hemangioblastoma, which demonstrated typical signal voided vascular structures revealed homogenous enhancing mass. A very rare intramedullary cavernoma at the level of cervical cord showed typical dark signal hemosiderin rim and variable staged hemorrhage in the mass. Conclusion : Although, MR imaging appearance of intramedullary tumors is nonspecific, and it is often impossible to differentiate with certainty between the various possible tumors, especially ependymomas and astrucystomas. However, MR findings of hemangioblastoma and cavernoma are specific and possible to diagnose. MR imaging is the unquestioned technique of choice in demonstrating and differentiating the intramedullary tumors.

Health Risk Appraisal(HRA) is usually defined as a process by which we expect of individual's chances of acquiring specific diseases within a defined period of time. The concept of worksite as an area of health maintenance and promotion is newly developing. Our movement for health promotion of employees has been increasingly known in the worksite. The aim of this study is to develop health risk appraisal tools about health promotion at the worksite for employees. We performed this study by two steps: one step was to develop a HRA questionnaire of worksites in Korea, another was to evaluate the reliability of the questionnaire. For developing HRA questionnaire, we reviewed scientific examples at first, and then weighted the score by delphi. To evaluate the reliability of developed questionnaire, we carried out survey by test-retest method. A total of 131 employees completed HRA questionnaire on two times. The results are as follows. The total score of health risk in unhealthy workers was higher than that of healthy workers. The range of test-retest reliability of responses to the questionnaire was 0.57-0.94. Therefore it seems that this questionnaire was very suitable to assess the health behavior of workers. In conclusion, the developed HRA questionnaire can be used as a tool for evaluating health behavior and for providing health counseling materials.
