김포시와 고양시 일대의 한강하구 지역은 우리나라에서 재두루미의 가장 중요한 월동지 및 중간기착지로 알려져 있지만, 이 지역의 조류 서식환경은 심각한 개발압력과 인간의 간섭으로 인해 지속적으로 나빠지고 있다. 따라서 본 연구에서는 2007-2008년과 2011-2012년의 월동시기에 본 지역에 도래하는 재두루미를 대상으로 월동 개체군 크기 변화와 월동지역 내에서 과거와 현재의 취식지역 이용 현황 등을 조사하여 개발행위가 이들의 서식에 미치는 영향을 확인하였다. 본 지역에서 월동하는 재두루미 개체군은 평균 124.9개체(2007-2008년)에서 59.0개체(2011-2012년)로 감소하였으며, 주요 취식지역에서 확인된 개체수는 평균 77.7개체에서 24.1개체로 감소하여 월동개체군의 감소폭에 비해 주요 취식지역의 이용 개체수의 감소폭이 더 크게 나타났다. 유형별 분석에서는 가족군에 비해 무리군의 개체수가 많이 감소한 것으로 나타났으나, 홍도평 지역의 가족군 이용 개체수는 변화가 나타나지 않았다(Mann-Whitney test. Z=-0.26, p=0.979). 그리고 과거 다수의 재두루미가 주요 취식지역으로 이용하였던 송포동과 평동지역은 2012-2013년 조사에서는 거의 이용하지 않는 것으로 나타났다. 이는 위 지역의 개발행위(예: 제 2자유로 건설 등)와 깊은 연관성이 있는 것으로 생각된다. Han-river estuary in Gimpo and Goyang city is well known as one of the most important wintering and stopover sites for migrating White-naped Crane (Grus vipio) in Korea. Nowadays, habitat quality of this area is getting worse due to serious development pressure and high human disturbances. So, we wanted to know whether development actions affected total wintering population change in Han-river estuary and feeding group pattern of White-naped Crane in main feeding habitats between the 2007-2008 and 2011-2012 wintering period. Average wintering population was decreased 124.9 to 59.0 and population of main feeding site also decreased 77.7 to 24.1. But decrease rate of main feeding site population was higher than total wintering population. Non-family feeding population was more decrease than family feeding population in the flock type analysis. But family feeding population of Hongdopyong was maintained from past and present (Mann-Whitney test. Z=-0.26, p=0.979). However, almost all White-naped Crane din not use both feeding sites, Pyong-dong and Songpo-dong, where were deteriorated habitat quality by human act.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

EC市場統合과 生命保險

The European Community has always looked on services as an essential part of the integration process, but paid little attention to it. In this paper, I proposed to look into the life insurance sector of the European Community in some detail, and focused on life insurance that can in principle be traded. Many life insurers have up to now been sheltered from international compitition by government regulation except UK. For that reason little multinationalization of insurer has occured. The sector's low degree of integration is also apparent in the fairly hige differences in prices among EC countries. The case of insurance, a sector in which economies of scale are important, show that both the freedom of provide services in another country and freedom of establishment are now put into practice, leading to a growing interpenetration of markets and multinationalization of firms. Clearly, all EC's life insurers will have opportunity to share in one important benefit that should emerge from the creation of the single European Market. But the third country (non EC countries) looked on the European Community may become “Fotress Europe” by reciprocal treatment. Consequently, life insurers are having to plan their European strategies. At the same time they must be taking into account in their strategic planning other major changes that are occuring in insurance market.

Jung, Ji-Yong was one of the most important poets that marked a new epoch of contributing greatly to the history of Korean modern poetry and creating many refined modern poetic words with Korean flavors. He wrote the 16 poems dealt with Catholicism among about his 140 poems in his life. His confession of his faith in Catholicism and his poetic characteristics through them led the author to come to obtain the following findings: First, secular human beings keep themselves in awe of the Absolute and make themselves obedient to him. Second, the poet expressed how to do their duty and how to behave as creatures. Such poetic words as water, fire, sky, sun, sea, universe, stars, trees, lakes, etc. Were often used in his poems. Firmly believing that God is the Creator of all these things and the Master, he made use of the images of his poems in terms of the heavenly body and natural objects.

Thin amorphous carbon films were deposited by a Q-switched Nd;YAG 532nm with beam power density of ?? on the high purity graphite (99.7%). The pressure of vacuum chamber was ?? Torr. In order to estimate the quality of the Pulsed Laser Deposition films one of the most important optical properties, bandgap energy, was characterized by transmission and reflection in the range of the visible, and an optical direct bandgap energy of 2.45eV and indirect bandgap energy 0.36eV were obtained. Surface morphology of amorphous film was investigated by AFM (Atomic Force Microscopy). Its surface roughness is 70nm. Comparing our results with the published values in the literature we have confidence that our films show the good quality for optical properties.

This earth has been threatened by environmental pollution. Particularly the issue of the oil pollution damage became a major concern in worldwide after Torrey Canyon disaster. Moreover, such oil pollution bring about a serious environmental contamination and a large amount of economics losses. Therefore the purpose of this paper is to analyze the prevention law of marine oil pollution and to suggest the improvement of that. Marine pollution has become a major occupation of the international community. At the same time, marine pollution has presented all sector of the industry with one of the most significant challenge. However, most important had been the change of international awareness about the dangers of environmental deterioration. In the next, legal system is established for marine oil pollution damage. Accordingly, for the purpose of prevention for marine oil pollution damage, I will suggest as follows: Firstly, it is necessary to introduct rigional coorperation system and concept of marine environment management. Secondly, establishment of fund on Korea's own. However, it is most important to preserve our marine environment.

Between January 1999 and September 2001, 948 sera (120 from each province except 108 from Chungbuk) from 8 provinces were sampled from Korean goats. All the samples were serologically tested for Leptospira spp. By the microscopic agglutination test against four L. interrogans serovars including canicola, icterohaemorrhagiae, pomona and hardjo, 948 Korean goats were confirmed as 11 seropositives (1.2%) only infected with L. icterohemorrhagiae. All positive sera were collected from Gyeonggi (5), Gangwon (4) and Chungbuk (2). Titration of them were classified as 1:100 of 10 sera except one case with 1:200 from Gyeonggi. It was meaningful that the pathogen in Korean goats was mainly distributed in the northen part of the country. Consequently, the results in the study were confirmed and analyzed the recent status of infection of leptospirosisas zoonotic agentsome in Korean goats.

한동운,권용국,문진산,윤소라,위성환,장환,탁동섭,이태욱,강문일 한국수의공중보건학회 2003 예방수의학회지 Vol.27 No.3

The 948 goat sera were serologically tested for ten pathogens including bovine viral diarrhea (BVD), bovine herpes virus type-1 (BHV-1) and parainfluenza virus type-3 (PI-3). By viral neutralizaion test, three pathogens including BVD virus, BHV-1, PI-3 were applied for screening each neutralizing antibody and its titration. Among 948 sera, there were 215 seropositives (22.7%) against BVD virus, 25 (2.6%) against BHV-1 virus, and 161 (17.0%) against PI-3 virus, respectively. In the seropositive cases to BVD virus, provincial prevalence of them were recorded as Gyeongnam(30.8%) for the highest one, while as Jeonbuk (15.8%) and Gyeongbuk(l6.7%) relatively for the lower ones. Among them, higher than 1:8 in antibody titration was classified as 74 cases (34.4%) which were suspected the cycle of its infection in their herds. Among the seropositives to BHV-1, it was relatively lower prevalence rate ranging from 1.7% to 6.7% that those of BVD virus and PI-3, but more importantly they were prevailing across the country. Most of the seropositive cases (42.9%) to PI-3 were classified as 1:4-1:16 in titration, but also distributed all around the country. The prevalence in goats varied according to areas (15.8 to 30.8%). Related to the provincial prevalence of three viral agents in Korean goats, it seemed that three viral pathogens would be directly or indirectly involving in various disorders as primary or secondary causative agents resulting in decreased productivity.

흰쥐에 있어서 피부노출 차단이 피부조직의 Xanthine Oxidase 활성에 미치는 영향

한선일,전태원,윤종국 대한의생명과학회 2000 Journal of biomedical laboratory sciences Vol.6 No.1

횐쥐에 있어서 피부의 공기차단이 피부조직의 xanthine oxidate (XO) 활성에 미치는 영향을 검토하고자 직경 46 mm, 높이 10 mm인 petri dish-shaped glass chamber에 순간접착제 (α-cyanoacrylate)를 이용하여 실험동물의 등 부위 피부조직에 부착시켜 10일간 공기의 접촉을 차단하였다. 공기 접촉 차단 5일째에 피부의 땀 축적량은 약 400 mg 정 도이었으나, 10일째 에는 약 25 mg으로 감소하였다. 5일간 피부차단 시 피부조직 중 XO활성은 대조군에 비해 증가하였으며,그 증가율은 chamber 내의 땀 축적량과 관련하여 10일간 피부차단군 보다 높게 나타났다. 5일간 피부차단 시 XO의 기질 농도 변화에 따른 반응 속도를 관찰한 결과, 대조군에 비해 V-max치가 높게 나타났다. 이상 실험 결과를 보아, 피부의 공기접촉 차단으로 피부조직 중 XO효소 활성이 증가된 것은 이 효소 단백 합성 유도에 기인되며, 이는 피부조직에서 oxygen free radical의 생성을 유도하여 외부 환경에 대한 방어장벽작용에 관여할 것으로 생각된다. To investigate an impact of skin occlusion on the dermal xanthine oxidase (XO) activity, the dorsal part in rats was covered with closed petri dish-shaped chamber, 46 mm in diameter and 10mm in height, which was made of glass. The crack between top of chamber and skin was sealed by an adhesive agent. After 5 days, the quantity of sweat accumulation was about 400 mg, whereas after 10 days that was decreased about to 25 mg. The 5 days skin occlusion showed the more increased activity of dermal XO compared with the control, and the increased ratio of enzyme activity to the control was higher than that of 10 days skin occlusion, with the increase being associated with sweat accumulation in chamber. Furthermore, the Vmax of dermal XO in 5 days skin occlusion was higher than that in the control. In conclusion, it may be hypothesized that the XO system may play an role for defence mechanism in dermal tissue.
