Meteorological observatorg from Januauy l973 to December 1977 to calculate the stability of the artifical fish reef that will put off the coast of Jeju Island. The result obtained were summarized as follows ; 1. Maximum wind direction and velocity of Jeju coast were NW 17.4% and 8.8m/sec. That of Seogwipo coast were NE 34.0% and 6.7 m/sec. 2. The average wind waves in the coast of Jeju Island were as follows; <표본문참조>

Background & objectives : An increase of calcium influx during alcohol withdrawal state may contribute to neuronal hyperexitability, which cause delirium tremens(DT). Some investigators have found calcium channel blockers effects in prevention of DT in experimental animals. Therefore we evaluated the preventive effects of calcium channel blocker(nimodipine) and benzodiazepine(chlordiazepoxide) on the development of DT in alcohol withdrawal seizure(AWS) patients. Method : A total 59 patients with AWS were divided into three groups according to the management nimodipine-treated, chlordiazepoxide-treated, and control(no specific medication) groups. We compared the incidence rates of DT in the three groups. Results : Total incidence rate of DT was 30.5%(18 of 59 patients). There were 6 DTs of 18 patients(33.5%) in nimodipine-treated group, 4 of 21 patients(22.5%) in chlordiazpoxide-treated group, and 8 of 20 patients(44.0%) in control. Conclusion : The control group(44.0%) showed the highest incidence rate of DT. And nimodipine-treated(33.5%) and chlordiazepoxide-treated group(22.5%) were followed. However, this result failed to demonstrated statistically significant differences due to small numbers size.

The purpose of this study was to provide health related informations to establish better cultural welfare policy of government. The data of korean on the physical physique(height, weight), physical fitness and health related variables(smoking, drinking, % body fat, blood pressure, cholesterol level, etc.) were compared with data of other countries. The coclusions of this study were as follow: 1. The ratios of smokers and drinkers of Koreans were higher than that of Japanes. 2. The height and weight of middle aged Koreans were higher than those of Japanes at the same age. 3. Japanes wemen showed higher phsical fitness level in 50m run than Korean women. 4. Disease rate of Korean men and women showed a increasing tendancy every year.

Underwater ambient noises were investigated at 12 points in the eastern coast of Cheju Island The underwater ambient noise was present as a sound pressure level for each frequences. The results were as follows: 1 The sound pressure level of the underwater ambient noise was the highest of that in 12 points at 100 m in the depth of water at station D. 2 The vertical average sound pressure level at 200Hz was measured at 10m. 50m and 100m in the depth of water The values were 88dB. 87dB and 90dB, respectlvely. 3 The average sound pressure level on 12 points was measured 88 dB at 200Hz in the frequency.

모슬포 연안에서 이용되는 방어 曳繩釣 漁具를 개량하여 제작한 무단 曳繩釣 漁具와, 이것의 幹繩을 연속 회전시키는 회전기기를 조합해서 방어 자동 예승조 어구를 만들어서 해상실험한 결과는 다음과 같다. 1. 技繩과 낚시들의 幹繩에 감아지는 현상은 A형 漁具 幹繩의 길이 450m, 曳引速力 2.5m/sec인때 낚시의 수심은 58m 추정되었다. 2. 幹繩의 길이를 450ㅡ, 曳引速力 2.5m/sec인때 水力遊抗은 A형 165kgw B형 190kgw이었다. 3. 방어의 游泳層에 따라서 幹繩의 回轉速度, 幹繩의 길이, 漁船의 曳引速力으로서 漁獲水深을 調節할 수 있었다. 4. 釣獲된 방어의 處理, 낚시와 미끼의 交換을 回轉器機의 하나의 電源 開閉器로서 가능하기 때문에 방어 曳繩釣 漁具의 省力化가 되었다. Yellowtail(Seriola quinqueradiata TEMNINCK et SCHLEGEL) are mainly caught by trolling gear around the coast of Cheju Island. In this study conventional trolling gear was made automatic by employing an elctrical elctrical rotary device. 1. Two types (A and B) of trolling gear were tested and the degree of line tangle was found to be slightly more in B type. The total length of A type line 450m and depth of hooks was 58m when the trolling speed was 2.5m/sce. 2. The hydrodynamic resistance was 165KgW in A type and 190 KgW ir. B type when total length of line was 450m at a towing speed of 2.5m/sec. 3. According to shoal level the optimum catching depth can be controlled by altering rotating speed, length of main line and towing speed of fishing boat. 4. Removing fish from hooks and replacing hooks and bait can be achieved by the use of a cut-out switch. By automating the conventional trolling gear in this way a considerable reduction of labour is possible.

Inspite of immunization, TETANUS remains a disease with a high morbidity and mortality rate. Tetanus has been still occurred more frequently in developing countries where immunization programs are inadequate. In Korea, there is a routine immunuzation schedule with diphtheria, pertussis, and tetanus(DPT) vaccines at 2,4,6 month after birth at 18 month. But further prophylactic programs are not exist. Moreover, we have usually used only passive immunization, tetanus antitoxin, as a prophylactic regimen for injured patients instead of guidelines of Center for Disease Control. The purpose of this study was to assess the baseline tetanus immunity state and to suggest the proper immunization schedule and adequate prophylactic guideline for injured patients in Korea. One hundred thirty one trauma patients from emergency department of Severance hospital from September to November of 1993 were included. Antietanus antibody titers of the patients were analyzed by ELISA assay. The mean antitetanus antibody titer was 0.728 ±0.236IU/mL. The titers were diminished rapidly with age. In pediatric group(age under 15), the mean titer was 3.251 ±0.426 IU/mL and in geriatric group(age over 64), the mean titer was 0.007 ±0.002 IU/mL which was below the minimal protective antibody titer(0.01 IU/mL). While all of the pediatric patients have protective antibody titer, only 69.2% of young adults(15-39, n=65), 56.7% of adults(40-64, n=30), and 57.2% of geriatrics(>65, n=14) have protective antibody titer. Our results suggest that tetanus prophylaxis is unnecessary in the age under 14. In other age groups, however, our data strongly support the need of prophyulaxis.
