오존을 이용한 Parathion과 THMs 의 제거

김태동,나미정,유건상 안동대학교 환경연구소 2001 환경연구 Vol.1 No.-

It is well known that biological treatments are not able to remove all organic compounds, especially if they are toxic and refractory in the environment, from the contaminated water. Thus, they accumulate in the effluent water, causing an increase in pollution of our natural environment. The present study is directed towards the removal of non-biodegradable organics like parathion and THMs using ozone that are noticeable recently in the third treatment of contaminated water. In order to evaluate performance of ozone treatment, such parameters as the concentration of ozone, reaction time, the concentration of organics of interest, and the change in pH were examined. At the same time, the removal efficiency of above-mentioned organics by hybrid O_(3)/activated carbon treatment was also investigated, comparing with O_(3) treatment alone. In conclusion, the removal efficiency of parathion and THMs by O_(3) treatment alone was approximately 70% and less than 10%, respectively. Whereas, O_(3)/activated carbon treatment represented higher efficiency, showing almost 100% and 95%. It proves that hybrid O_(3)/activated carbon treatment for the removal of organics that are resistant to the environment is superior to ozone treatment alone.

Objective : Because the cause and etiology of chronic headache is not yet fully explained, the treatment of this symptom is not simple. This study compares the effects of aroma acupuncture and normal acupuncture applied an chronic headache patients, in order to establish a primary data for further studier of new treatments and developments of new practical acupunctures. Methods : 38 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as Chronic Headache patients. The qualified patients were classified in to two groups, aroma acupuncture group(Aroma AT group, n=23) and normal acupuncture group(AT group, n=15). Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes in both the groups. The effects of both groups were analyzed using VAS scores and BPI(Brief Pain Inventory). Results : The VAS pain scores improved significantly in both groups. The decrease rate was larger in the Aroma AT group(p<0.05). The BPI scores for the both groups also decrease. The improvement in the Aroma AT group was larger(p<0.05). Conclusion : Aroma acupuncture applied on chronic headache patients showed effects of relieving pain, improving general activities, changing the mood, and improving sleeping behaviors. These effects were analyzed using VAS scores and BPI. The Aroma AT group showed significant changes of VAS and BPI compared to the AT group, suggesting that this new practical acupuncture is very effective when treating chronic headaches. Further researches are needed to evaluate the distinct functional mechanism of aroma acupuncture, but this study is meaningful in the sense that it will act as a fundamental study to build on.

Beck Depression Inventory를 이용한 내과 환자의 우울성향 조사 보고

반건호,염태호,한홍무 大韓神經精神醫學會 1987 신경정신의학 Vol.26 No.3

It has been known that many medically ill patients have psychological problems, such as depression or anxiety. Many have attempted to define these problems objectively and several self-rating devices for depression or anxiety have been developed. This study was designed to investigate the characteristics of depressive trends in medically ill patients. The author performed Beck's Depression Inventory (BDI) on 82 inpatients & 93 outpatients in Kyung-Hee University hospital and 200 normal subjects from August to September, 1986. The results were as follows; 1) In comparison of the three groups, the difference of total score of BDI was significant, especially between inpatients and normal subjects. 2) The total score of BDI of female was significantly higher than that of male in outpatients and normal subjects. 3) The BDI score of low educational group was significantly higher than that of high educational group in outpatients and normal subjects. 4) In normal subjects, BDI score was significantly increased by aging, but not in inpatients and outpatients. 5) Categorized as depression were 39.0% of inpatients, 30.1% of outpatients, and 27.0% of normal subjects, when the tentative cut off score was 21. 6) The significant items among three groups were items, No. 3, 15, 16, 17, 18, 19, 20 and 21, which were manifestations of somatization in the depression. 7) Depending upon above findings, BDI is thought to be a useful device for screening depressive trends in medically ill patients.

흰쥐의 파라쿼트 중독모델에서 폐손상에 대한 N-acetylcysteine과 Methylprednisolone의 효과

최태환,조건현,오동렬,김세경 대한응급의학회 2001 대한응급의학회지 Vol.12 No.3

Background: This study evaluated the inhibitory effects of N-acetylcysteine(NAC) and methylprednisolone on lung injury in the paraquat-poisoned rat model. Methods: Sixty rats were divided into four groups(n=15 in each group) accordingly to the drug administered : group I, only intraperitoneally injected paraquat (20 mg/kg); group II, intraperitoneally injected paraquat and NAC(300 mg/kg); group III, intraperitoneally injected paraquat and methylprednisolone(60 mg/kg); and group IV, intraperitoneally injected paraquat, NAC(300 mg/kg), and methylprednisolone(60 mg/kg). On the 7th day after injection, the survival rate of experimental rats and the positive area of collagen fiber in the injured lung stained by Masson's trichroms were evaluated. Results: 1. There were no differences in the 7-day survival rates for the four groups. 2, The percent of collagen fiber for group II(6.3 ± 4.7%) was significantly decreased in comparison with that for group I (14.4±9.7%). 3. The percent of collagen fiber for Group III(13.2±5.9%) was not significantly different from that for group I(14.4±9.7%). 4. The percent of collagen fiber for Group IV(6.9±4.6%) was significantly decreased in comparison with that for group I, but was not different from that for group II. Conclusion: These results suggest that NAC protects against pulmonary fibrosis in paraquat-poisoned rats whereas methylprednisolone does not protect against pulmonary fibrosis.

This study was carried out to study the effects of plant growth regulators on the seedling growth of red pepper and to examine the possible utilization of these materials. Seedlings at 3-leaf-stage were spraied with five kinds of treatments ; once with 20ppm GA solution, twice with 4000 times Atonik solution at 1 week interval, once with 1000ppm B-9 solution, or once with 1000ppm CCC solution, while seeds were treated with 10, 30, 50, 70, and 100ppm Paclobutrazol solution. Plant height, stem diameter, dry weight, root activity, chlorophyll content, leaf thickness, width and length of palisade cell and number of stomata were measured. The result were summarized as follows : 1. GA increased plant height at the early stage, but it reduced at the later stages. Atonik also increased plant height. 2. Root activity, Leaf thickness and palisade cell size were increased by Atonik. 3. GA reduced chlorophyll content at the early stages, but it was similar to other treatments at the later stages. 4. The highest number of stomata was resulted by CCC, while GA showed the opposite result. 5. Root length, weight of stem, leaf, root, and whole plant were increased by Paclobutrazol at 30 -50ppm, at with concentration healthy seedlings were produced. However, higher number of fruits, greater maximum fruit weight and higher yield of pepper were obtained by seed treatments with 10-30ppm paclobutrazol solutions.
