Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

Our has been advanced in the organization of society with rapid industralization for more over 30 years. Gravitation of the population and traffic increase made change in life style and brought about a lot of noise pollution which is not able to be confirmed in sight. The damage of traffic noise will be a serious problem, so the effective and economical countermeasuring of noise will be proceeded when we build up a large building or housing complex and it also needs enlightment activity in order to reduce sound by improvement of how drive. So, It is possible to be suggested as follows 1) Enforcing the every-ten-day limit on auto usage continuously. 2) Expended execution of noise restriction area. 3) Improvement of procedure in parceling-out. 4) Establishment of walfare facilities on the road side. 5) Application of matrial excluded the outside sounds in the construction on road side. If we consider environmental city condition at the construction and city planning, it is possible to minimize the noise pollution, to make a pleasant environment and to contribute the national health improvement.

혈액에서 연속 분리된 Staphylococcus epidermidis의 항균제 내성 및 Pulsed-Field Gel Electrophoresis 양상

최인옥,정숙인,신동현,박영규,신종희 대한감염학회 2004 감염과 화학요법 Vol.36 No.5

목적 : 혈액배양에서 Staphylococcus epidermidis가 분리될 경우 임상적 의의를 판정하기가 쉽지 않으나, 일반적으로 연속해서 분리된 균주가 동일한 유전형을 보이면 균혈증의 원인균일 가능성이 높다고 한다. 재료 및 방법 : 동일한 환자(12명)의 혈액에서 연속 분리된 S. epidermidis 각 2주씩을 대상으로 PFGE를 이용하여 유전형을 분석하여 동일 균주가 분리되는지 유무를 조사하고, 이를 항균제 내성양상 및 균주간의 분리일 간격과 비교하여 보았다. 결과 : 동일인에서 분리된 두 균주간의 PFGE 양상을 비교한 결과, 8명(66.6%)에서 분리된 균주는 동일한 PFGE 양상을 보였으나 4명(33.3%)에서는 서로 다른 양상을 보였다. PFGE 양상이 동일한 8명 중 7명에서는 항균제 내성양상도 동일하였으며, PFGE 양상이 서로 다른 4명에서는 항균제 내성양상도 서로 달랐다. 따라서 동일인에서 연속 분리된 균주에 대한 PFGE와 항균제 내성검사의 일치율은 91.7% (11/12)였다. PFGE 양상은 동일 환자에서 균이 분리된 시간 간격이 4일 이내 일 때 88.9%(8/9)에서 동일하였고, 분리일의 간격이 5일 이상일 때는 모두(3명)에서 서로 다른 PFGE 양상을 보였다. 결론 : 혈액에서 연속 분리된 S. epidermidis 균주의 PFGE 양상은 상당 수 환자에서 서로 달라, 동일 균종일지라도 오염의 가능성도 상당히 높음을 알 수 있었다. 연속 분리된 S. epidermidis 균주의 항균제 내성양상과 분리된 날짜 간격은 유전자형별 검사가 어려울 경우, 동일균주가 연속 분리되었는지 유무를 아는데 도움을 주리라 생각된다. Background : The significance of Staphylococcus epidermidis positive blood cultures is difficult to determine, but repeated isolation of the same organism with the same genotype is suggestive of true bacteremia. Materials and Methods : Two sequential isolates of S. epidermidis from blood cultures of the same twelve patients were genotyped by PFGE. The results were compared with those of antibiotyping and isolation time intervals between the two strains. Results : The two sequential strains from each patient had identical PFGE patterns in 66.6% (8 of 12) of the patients and two different types in 33.3% (4 of 12) of the patients. Antibiotypes of the two isolates from the same patient were different in all 4 patients whose isolates had different PFGE patterns, and they were the same in 7 of 8 patients whose isolates had identical PFGE patterns:the PFGE results were in agreement with the antibiotyping for 91.7% (11/12) of patients. The isolation time interval between the two strains was ≤4 days in 9 cases, 8 of which had identical PFGE patterns. In the 3 cases whose isolates had different PFGE patterns, the isolation time interval between the two strains was ≥5 days. Conclusion : These data showed that two consecutive isolates of S. epidermidis from blood cultures had different PFGE patterns in 33% of patients, suggesting a high prevalence of contamination. In the absence of genotyping measures, both antibiotype and isolation time interval can be alternative and useful tools for determining strain relatedness of sequential isolates of S. epidermidis from blood cultures.

현대복식에 나타난 원시주의(Primitivism)에 관한 연구

崔在欄,柳淑姬 啓明大學校 生活科學硏究所 1995 科學論集 Vol.21 No.-

The purpose of this study is to examine the background of the advent of primitivism in the modern age and how primitivism has been expressed in the fine art. At the same time, this thesis will survey the techniques of primitivism applied to the modern clothing, reviewing the styles by which primitivism has been expressed. The characteristics of primitivism in the modern clothing can be summarized as follows: First, primitive modern art, by the use of strong colors, and primitive signs and symbols, has expressed primitive life images, local images, and abstract and symbolic images, challenging the established concept of images. Secondly, the primitivism in the modern clothing meets the ideals the modern art sought after in the late 19th century and in the early 20th century. The creativity added to the fashion confined to artificial techniques resulted in simple and plain beauty in the clothing. The innocent emotional expression, creativity and witty expression transcend the ordinary life and make people recognize the implied complex concept. They also express the primitive thought and the mystic, imagination, abstraction, and life. Simple styles and various materials, including the motifs of animals and plants, the expressiveness of patterns, colors and accessories representing nature, are all used to express the images of primitivism. Thirdly, the expressive techniques applied in the modern costume such as the use of primitive materials, themes of animals, incompletedness, the effect of handmade, and the effect of decoration through body conscious, are not only the resistance to the dehumanized mechanical elements of science and technology, but an effort to recover humanity. Considering what has been examined, so long as the destruction of nature and dehumanization go on, primitivism in the clothing will continue as an effort to recover the innocence of nature, longing for the primitive. This trend, especially in the present anticipating 21th century, will serve to expand the realm of expression and to find a new method and direction for the modern clothing.

셀룰로오스에 브롬화비닐의 그라프트 반응과 그 방염성에 관한 연구

최금숙,조성무,채희주,유학수 연세대학교 자연과학연구소 1987 學術論文集 Vol.18 No.-

셀룰로오스에 방염성을 부여하기 위해 산화-환원 개시제인 Ce^??이온을 이용하여 브롬화비닐을 그라프시켰다. 일반적으로 그라프트율은 시간에 따라 증가하다가 정상 상태에 도달하고,단량체 농도에 비례하며 극대치를 갖는 개시제의 농도가 존재한다. 그라프트율의 증가에 따라 한계산소지수가 높아져 방염성을 보임을 알 수 있다. To impose the flame retardant properties on cellulose, vinyl bromide was grafted on cellulose by redox initiator Ce^??. Generally, graft yield increases according to graft reaction time but as time goes on it shows steady state, however, it keeps on increasing in proportion to monomer concentration and has an optimum initiator concentration. It was found that LOI was proportional to graft yield and grafted cellulose had flame retardant properties.

고춧가루내의 고추씨 함량이 김치발효와 항돌연변이 활성에 미치는 영향

최선미,전영수,이숙희,박건영 부산대학교 김치연구소 2002 김치의 과학과 기술 Vol.8 No.-

The fermentation characteristics such as pH, acidity, lactic acid bacterial counts and panel taste of kimchi, and antimutagenic activity of kimchi were studied when the kimchi prepared with different ratio of seed (S) pericarp (P) in red pepper powder and fermented at 15℃. The pHs of P:S = 9:1 kimchi and P:S = 7:3 kimchi decreased gradually during the kimchi fermentation, however, pHs of P:S = 5:5 kimchi and P:S = 3:7 kimchi decreased very fast during the fermentation. The counts of Leuconostoc sp were high in P:S = 9:1 kimchi and P:S = 7:3 kimchi but the levels were low in P:S = 5:5 kimchi and P:S = 3:7 kimchi. Whereas Lactobacillus sp counts were low in P:S = 9:1 kimchi and P:S = 7:3 kimchi, but the counts were high in P:S = 5:5 kimchi and P:S = 3:7 kimchi during the fermentation. P:S = 3:7 kimchi showed the highest prevalence in the panel taste of the kimchis and the P:S = 3:7 kimchi resulted in the lowest prevalence. The antimutagenic activities of the kimchi juices were studied by Ames test using Salmonella typhimurium TA100 and SOS chromotest using E. coil PQ37. As the ratio of the seed increased, the antimutagenicities increased. Among the kimchi samples, P:S = 5:5 kimchi significantly reduced (p<0.05) the mutagenicities induced by aflatoxin B_1(AFB_1) in Ames test and SOS response against N-methy1-N'-nitro-N-nitrosoguanidine (MNNG) in SOS chromotest. From the results of the experiments, the P:S = 7:3 kimchi seems to be the best seed ratio of red pepper powder for the preparation of kimchi in terms of fermentation characteristics and antimutagenicity of the kimchi.
