Drowning is the second most common cause of accidental death of children in Korea. But the study of near-drowning is very rare in Korea. The purpose of our study is to determine the factors that may influence survival on the basis of submersion time, consciousness state upon admission to hospital, the kinds of water, laboratory findings and neurological outcomes. The survey was performed by a retrospective cohort study on 28 near-drowning victims of less than 15 years of age who were admitted to the emergency room in the Chosun University Hospital between May 1988 & May 1997. The results were as follows :1)Sex distribution was 22 males and 6 females. 2) Submersion time was <5 minutes in 9 cases, 5-9 minutes in 6 cases, 10-14 minutes in 5cases, 15-19 minutes in 3 cases, ≥20 minutes in 5cases. 3) Comatose patients upon arrival were 6/7 cases in the death group(86%) and 2/21 cases in the improved group(10%). They had unfavorable outcomes(P<0.05). 4) The first PH value was mean 7.02±0.12 in the death group and mean 7.31±0.13 in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05) 5) The patients who gad increased blood glucose concentration were all 7 cases in the death group and 12/22 cases in the improved group(54%). The mean blood glucose concentration was mean 424.7235.6㎎/㎗ in the death group and mean 140.182.7㎎/㎗ in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05). 6) The patients who had pulmonary edema upon arrival were all 7 cases in the death group and 1/21 cases in the improved group(46%). They had unfavorable outcomes(P<0.05). 7) The patients who had been submerged more than 15 minutes were all 7 cases in the death group and 6/21 cases in the improved group(5%). They had unfavorable outcomes(P<0.05). We conclude that pediatric victims of near-drowning can be assigned to high or low likelihoods of unfavorable our outcomes with the use of five variables ; comatose mentation upon arrival decreased initial blood pH, increased initial blood glucose concentration, pulmonary edema, and maximum submersion time estimated longer than fiften minutes. This prediction rule may be useful if it can be validated in another cohort.

본 연구는 특수 콘크리트를 사용하여 가로경관 시설물 관련 제품을 생산하기 위한 기초 자료를 얻을 목적으로 수행하였다. 조사는 기존의 도시 가로를 구시가지, 신시가지, 문화거리로 구분하여 가로 경관 시설물을 현황을 조사하였다. 장소에 따른 가로 경관 시설물을 종류는 크게 다르지 않았으며, 시설물의 소재(사용재료)는 철제품이 주종을 이루고 있었다. 또 이들 가로 경관 시설물은 도로에 관련된 정보 전달을 위한 기능성에 치중하고 있고, 경관 기여도는 낮은 것으로 평가되었다. 이렇게 조사된 결과를 토대로 하여 경관 기여도를 높일 수 있는 수목용 플랜터(planter for trees and shrub)와 자연성의 도입을 유도할 수 있는 생태블럭(eco-block)의 모형을 제시하였다. This study is conducted to collect basic data for special concrete material to be applied for making street furniture and related products. For this purpose, this study first classified existing city streets into old town area, newly developed area and cultural street, then surveyed the number and the kind of street furniture located in them. In result, the survey showed that the street furniture was not different among the streets in terms of kind, and steel including nonferrous metal was used as the main material for it, and the contribution to the landscape was limitied. Based upon the results, we suggest the pilot models of a planter for trees and shrubs which can make a greater contribution to the surrounding landscape, and of an eco-block to give naturalness to the urban settings.

Changes in taste components of Backilju, an old Korean cleraed rice wine, were investigated. During brewing, pH and titratable acidity of mash were decreased or increased in the range of 3.41→3.81 and 8.62→6.74, respectively. The final product of Backilju filtrate, fermented for 100 days, contained 0.36% reducing sugar, 2.68% total sugar, 606.6 ㎎% total acid, 2.5 ㎎% volatile acid and 22.9㎎ solid/ml extract. Major volatile components analized by GC/MS methods were 3-methyl-1-butanol acetate, 4-decanol and dimethyl disulfide. Calcium(20.26ppm) was the most abundant, followed by magnesium(3.19ppm) and zinc(1.87ppm). Nucleotides and their related compounds were inosine(0.12→0.44 mM/ml), ADP(0.16→0.33 mM/ml) and hypoxanthine(0.33→0.04 mM/ml). Compared with other Korean traditional Yakju, Backilju contained more total acid and mineral but less sugar and volatile acid.

Rubi Fructus is a well known remedy for female infertility, especially due to lack of kidney-yang or shenyangxu(???). An attempt was made to evaluate the influences of Rubi Fructus (mature Rubus crataegifolius BUNGE, mature Rubus coreanus MIQ and immature Rubus coreanum MIQ) on the morphological changes of the ovary. The experiment was performed to investigate the effects of the seeds of mature Rubus cratagifolius BUNGE (W1), the seeds of mature Rubus coreanus MIQ (W2) and the seeds of immature Rubus coreanus MIQ (W3) on the formation of follicles in rat ovary. The results are as follows: 1. Results using three herbs of mature seed of Rubus cratagifolius BUNGE (W1), mature seed of Rubus coreanus MIQ (W2)and immature seed of Rubus coreanus MIQ (W3) clearly showed the stimulating effects on the increasing number of follicles in rat ovary. Of them, W1 increased the follicle formation by 171% compared to normal control after 4 days of treatment. In cases of W2 and W3, the formed numbers of the follicle were increased to 228% and 285%, respectively. On the other hand, the follicle formations of W1, W2, and W3 were most effective, showing 208, 258 and 266%, respectively, after 8 days of treatment. These results showed that effect of immature Rubus coreanus MIQ was similar to that of the mature Rubus coreanus MIQ without any differences. 2. The size of the follicle stimulated by W2 was about 1.0 mm, although the size of the normal control was 0.3 mm. However, those of W1 and W2 were about 0.5 mm, indicating that the treatments of the herbal extracts are also effective for the follicle size. Therefore, it was concluded that all these herbs showed the effects on average of follicles in ovary. Especially, mature Rubus coreanus MIQ showed the highest effect among them. 3. Fractions of W1-B, W2-B and W3-B, when each extract were separated by analytical HPLC(high performance liquid chromatography), showed the activities of follicle number and size of follicles in ovary. These results suggest that the effect of Rubi Fructus is related to treatment of female infertility due to ovulation difficuty. Of them, mature Rubus coreanus MIQ is the most potent effector on the ovulation in Rats.

Fifteen subjects were fitted with progressive additional lens and they were divided into 3 groups. The first group had never worn add for reading before and their adds ranged between +1.00 - +1.50D. The second group made up of wearers who had been wearing a standard from of bifocal before switching to progressive additional lens and their adds fell in the +1.75 to +2.00D range. The third group comprised subjects who had been wearing a standard form of bifocal before choosing the progressive lens and their adds utilized a +2.25 to +2.50D. After wearing identical near power in blended bifocal, 13 subjects preferred to wear the progressive additional lenses. The second experiment subjects were 20 people and had never worn pro- gressive lens before. The first group whose add ranged between +1.00 and +1.50D. 4 of 6 had never worn adds for reading before. Eight subjects com- prised a group whose add powers fell in the +1.75 to +2.00D range. Only one of these had not worn some addition for near before. The final 6 required adds of +2.25 and +2.50 and had been wearing a near point addition for some time. Some tried the blended lenses first and then the progressive lenses while some wore the progressive lenses before the blended. 15 chose the progres- sive additions, with two selecting blended lenses and 3 returning to a stan- dard form. The experiment reveals that given any opportunity to compare the optical aspects of both blended bifocals and progressive addition lenses, the over-whelming propotion of subjects selected a progressive addition lens. A blended bifocal, despite the fact that it also caters to cosmetic favor through its invisibility is not an actual substitute for or replacement of a progressive addition lens insofar as apparent optical features and patient comfort and preference is concerned.

Background: The current treatments of acute myocardial infarct(AMI) Include noninvasive method using thrombolytics and invasive methods such as primary percutaneous transluminal coronary angioplasty(PTCA) and coronary artery bypass graft(CABG)surgery. Although there are many studies comparing the effectiveness of noninvasive and invasive methods, when large clinical centers, 20% of totar hospitals, were excluded, most middle-sized hospitals lacked personnels and facilities for the invasive methods. Thus they opted for the noninvasive methods. Therefore, in this study, the clinical characteristics of AMI patients and the results of thrombolytic & conservative treatment were observed. Method: 137 patients with acute myocardial infarct, who visited KonKuk University Medical Center, ChoongJu Hospital during Sept. 1990 to Sept. 1999 were analysed retrospectively using medical records. Result: The sexual compositions of patients were 63.5% male, and 36.5% female. The mean age for male patients were 56±12.9, and for female patients 68.7±9.6 (p<0.05). The mean age for female patients was significantly older than male patients. The patients in the thrombolytic treatment group had mortality rate of 6.25% which is lower than that of the conservative treatment group at 12% (p>0.05). Conclusion: Although in our study, small number of acute myocardial infarct patients caused the statistical insignificance, rapid revascularization by thrombolytic therapy within 6 hours of onset of symptoms improved mortality rate and early ambulation. And we had good results on AMI with thrombolytic agent in ChungJu including near rural area as primary emergency hospital. Therefore a prospective research with greater number of subjects is needed to develop better treatments for AMI.

γ-Al_2O_3에 몰리브덴을 담지시킨 촉매를 고정층 반응기에 충전하여 벤젠과 같은 VOCs의 촉매산화반응 특성을 살펴보았다. 실험조건은 반응온도를 200∼500℃로 하고, 반응물인 벤젠의 농도를 1,000∼3,000ppm, 공간속도를 5,000∼60,000hr^-1의 범위에서 적용하였다. 연구결과, 벤젠의 전환율은 공간속도가 낮을수록 증가하고, 초기유입농도가 증가할수록 감소하는 것으로 나타났다. 몰리브덴이 담지된 촉매의 성능은 니켈을 제외한 구리나 망간등의 다른 전이금속에 대해서는 다소 떨어지는 것으로 나타났다. 벤젠의 촉매연소반응은 1차 균일반응으로 해석될 수 있었으며, 균일연소반응의 활성화 에너지값은 7.4kcal/㏖ 이었다. Catalytic oxidation characteristics of benzene (one of important source of volatile organic compounds : VOCs) was investigated in a fixed bed flow reactor using Mo/γ-A1_2O_3 catalyst. As operating variables of experiment, reaction temperature (200∼500℃), benzene concentration (1,000∼3,000ppm), space velocity (5,000∼60,000hr^-1) were applied. The experimental results showed that the conversion of catalytic oxidation of benzene was increased with decreasing space velocity, while it was decreased with increasing inlet VOCs concentration. Mo/γ-A1_2O_3 catalyst exhibited more or less low activity among several transition metals such as Cu, Mn, Cr, etc. except Ni. The catalytic oxidation reaction for VOCs(benzene) could be expressed as the first order homogeneous reaction the activation energy of which was 7.4kcal/㏖.
