1999년 10월에서 11월 사이에 남해안 일대의 홍민어 종묘 생산장에서 20~30열령의 치어가 척추만곡 및 이상유영을 하며 대량 폐사하였다. 병어는 특이 외부 증상이 없었고, 높은 누적폐사량이 바이러스 질병으로 의심되어, 조직학적 및 분자생물학적인 검사를 행하여 폐사원인을 확인하였다. 폐사개체의 조직을 H-E 염색하여 관찰한 결과 뇌와 안구의 신경세포에서 공포와 괴사가 관찰되었고, 전자현미경 관찰에서는 안구와 뇌에서 바이러스 입자가 관찰되었다. RT-PCR 결과에서는 ≒426 bp의 DNA 단편을 확인할 수 있었다. 이러한 결과로 홍민어에서 발생한 대량폐사는 바이러스성 신경괴사증(VNN)으로 진단되었다. Mass mortalities occurred among red drum lavae, 20 to 30 days old, culturing at hatcheries on southern costal area. No specific external signs were observed except abnormal swimming and spinal deformity. It was, however, suspected as a viral etiology due to high mass mortalities so that histopathological and molecular biological study was performed to evaluate the agent. Both vacuoles and necrosis were observed on nerve cells of brain and eye by H-E staining, and viral particles were observed on electronmicroscopic examination. On the other hand, DNA fragment, approximately 426 bps, was amplified with RT-PCR. The above results were able to diagnosis the etiological agent of mass moralities in red drum larvae as VNN(viral nervous necrosis)virus.

The objective of this study is to predict the high risk group of coronary artery disease from body mass index, blood pressure, fasting blood sugar and serum lipids level using the method of discriminant analysis. Variables with significant difference between coronary artery disease group and normal group were HDS-C, LDL-C/HDL-C, LDL-C, and TG. But the acuity did not exceed 70% in any single variable. As the results of discriminant analysis, statistically significant discriminant variables were HDL-C, T-chol, FBS and TG. The discriminant equation was(Y) = -0.06759(HDL-C) + 0.01498(T-chol),+0.01923(FBS) - 0.01421(TG) + 0.5187, and the overall discriminant power using the above 4 variables was 79.3%

Objective: The authors investigated the frequency of persecutors in persecutory delusions of the psychiatric patients who didn't undergo the arrest or traumatic injury, reside in Gwangju Jeonnam area, and were admitted to the hospital after the 5.18 prodemocracy movement in Gwangju in 1980 upward 10 years. Also this study investigated the frequency of the persecutors before and after the prodemocracy movement and in capital and Gwangju Jeonnam area. Subjects and Methods: Among the 896 patients who were admitted to department of psychiatry, Chosun University Hospital from Jan. 1. 1989 to Dec. 31. 1991, we choosed 144 patients with persecutory delusion who had lived in Gwangju Jeonnam area for 10 years after 5.18 prodemocracy movement as subjects. Persecutors were classified into 7 class: unspecified, family, neighbors, communist or spy, police or army or secret agent, impersonal, others. Results: 1) In our study, the frequency of persecutors was family, unspecified, neighbors, police or army or secret agent, impersonal, others, communist or spy in descending order. As compared to previous studies (1956-2003) including our study about frequency of persecutor at capital area and Gwangju Jeonnam area, and before and after 5.18 prodemocracy movement, 2) At capital area, in the early 1980s, police, family, neighbors, unspecified person was frequent in descending order. In the both of early 1970s, 1990s, neighbors, family, unspecified person, police was frequent in descending order. 3) At Gwangju Jeonnam area, in the early 1970s, family, unspecified person, neighbors, police was frequent in descending order. In the early 1990s, unspecified person and family, neighbors, police was frequent in descending order. 4) The police class was most frequent at capital area in the early 1980s. Conclusions: We suppose that class of persecutor in persecutory delusions of psychiatric patients are changing according to social change, and frequency of police class was decreasing in both of capital and Gwangju, Jeonnam area.

The purpose of this retrospective study is to investigate the effects of conscious sedation in an outpatient setting. Data from 292 patients (154 males, 138 females), sedated for minor oral surgery, were studied using various parameters including age and sex distribution, as well as according to procedures and each drug group. Results show that this intravenous conscious sedation technique is a safe and effective method of controlling behaviour, but one has to be prepared to deal with any emergencies or complications. The specific results are as follows : 1.Most procedures (265/292) were used to Valium mixed with Demerol and Midazolam mixed with Demerol. 2.Valium revealed a high incidence of pain upon injection and symptoms limited to daily activity and thrombophlebitis. 3.Nausea and vomiting manifested in the procedure using Demerol. 4.The patient manifested comfort similar in response to the same drugs used in another treatment.

Although a number of static pile load tests have been performed in this country, re-consideration on the interpretation and loading methods is needed, because of their less usefulness in practice. For this study, a static loading testing was performed for a long instrumented PHC pile, which was installed in asnd layer overlying thick soft clay. The shaft resistance of the pile had been monitored for a long time after installation, and then the static load testing was performed by the quick load test, unlike the recent Korean practice. Using the measured data, the elastic modulus of pile, residual stress and true resistance on the pile were determined. In the event, it was found that the residual stress on the pile, which remained prior to the static loading, significantly affects the shaft and toe resistances. Also, it was realized that the setup effect for the long pile is significant.

The main purposes of this survey are to identify the characteristics of entrants and to provide some suggestions for both a policy planning for entrants and student guidance. For this, entrants(N=868) who were admitted to natural science, engineering, education. fine arts, and other colleges of Chosun University(CU) in 1994 were surveyed with the questionnaire developed by authors. The questionnaire dealt with 1) demographic characteristics. 2) life environment - family relationship, family circumstances, economic conditions, 3) life during high school, 4) attitudes toward both the university and one's subject of study - major sources of informations about the university and attitude toward the university. major sources of informations about one's subject of study and attitude toward one's subject of study, 5) the plan of the university life and course after graduation, 6) interpersonal relationship, and 7) self-perception. The characteristics of entrants were globally examined, and differences between the sexes and differences among colleges in the characteristics described above, if any, were also mentioned. Some suggestions based on the results of this survey were provided in terms of both a policy planning for entrants and student guidance, Finally, one limitation of this survey was discussed from the standpoint of the generalization of the results and some suggestions for future surveys were also discussed.
