        홍현정 ( Hyun Jung Hong ),최현아 ( Hyun Ah Choi ),변병설 ( Byung Seol Byun ),박용하 ( Yong Ha Park ) 한국환경복원기술학회(구 한국환경복원녹화기술학회) 2013 한국환경복원기술학회지 Vol.16 No.6

        As ten years have passed since national parks were adjusted and released inceptively, it is the time for evaluating the effectiveness of the national park policy and improving it on the basis of the evaluation result. In this study, the method of appraising the environmental and socio-economical ripple effect on the implementation of national park regulation were provided, based on the institutional consideration, the environment analysis, the survey of residents consciousness, the statistical analysis and so on. It is applied to target sites where were released from national parks, and the policy direction was suggested for sustainable use and management of national parks. National parks, that exhibit various characteristics depending on geographical and local conditions, were categorized through the statistical approach. Released sites from Seoraksan National park, where was categorized as the core national park for sustainable use and management, were evaluated environmentally based on the time-series analysis of environmental thematic maps and socio-economically based on the survey on residents perceptions. As a result of this study, the environmental effect of released sites has been declined or threatened, and the residents` economic, social and living condition in these areas are still not improved(p<0.05) since the adjustment of national parks. Based on the policy approach reflecting regional characteristics, natural resources are kept and enhanced for the sustainable use and management of national parks. And a consensus on the national park policy of national park should be developed between local residents and voluntary participation and public awareness should be attracted from them, based on the construction and the supplement of the infrastructure.

      • 위성망에서 효율적인 순방향 에러정정 기법

        박태근,김영환,박재현,박현민,최병석 明知大學校 産業技術硏究所 1999 産業技術硏究所論文集 Vol.18 No.-

        In this paper, a new method of FEC(Forward Error Correction) using multi-stage Viterbi coder is proposed, with effectively reduce BER in satellite ATM Networks. In terms of structural complexity, proposed multi-stage Viterbi coder simpler than the traditional single-stage coder based on the same BER performances. And, through simulation, proposed coder shows excellent error correction capabilities compared with traditional FEC schemes. Also, we propose a selective FEC mechanism that adaptively changes the number of stages to satisfy the QoS(Quality of Service) requirements. This Selective scheme can be easily implemented using the PLCP(Physical Layer Convergence Protocol) frame structure.

      • Interleukin-2와 결핵균 30 kDa 항원이 구개편도 및 말초혈액 T 세포 증식에 미치는 상승효과

        박정규,박찬권,조은경,김화중,백태현,고필준,김병국,남부현,나기상,박찬일 충남대학교 의과대학 지역사회의학연구소 1995 충남의대잡지 Vol.22 No.1

        Widespread use of BCG has not controlled tuberculosis, and more effective vaccines are clearly needed. Although chemotherapy will remain the mainstay of antituberculosis treatment, the use of adjunctive immunotherapeutic modalitites is attractive, particularly in persons with drug-resistant tuberculosis. Administration of IL-2 or IFN-γto tuberculosis patients enhance bacillary elimination. Cell-mediated immunity is the critical protective immune response in tuberculosis. Mycobacterial antigens are recognized by T cells and that elicit production of protective cytokines are potentially important vaccine antigens. The 30 kDa antigen is secreted in large quantities by growing mycobacteria. That antigen elicits greater proliferation in lymphocytes from healthy tuberculin reactors than healthy tuberculin nonreactors. In this study, the T lymphocyte proliferative responses to 30 kDa antigen from Mycobactrium tuberculosis H37Rv were examined by using tonsilar and peripheral blood lymphocytes from PPD(+) and PPD(-) tonsilectomized persons. When cultured with 30 kD antigen, tonsilar mononuclear leukocytes and T cells of PPD(+) demonstrated more ^3H-thymidine incorporation than PPD(-) persons (stimulation index was 2.5 and 1.9, 0.8 and 1.0, repectively). Peripheral blood mononuclear cells (PBMC) and peripheral blood T lymphocytes were shown the similar responses to this antigen. The combination of IL-2 and 30 kDa antigen elicited a significant proliferative responsiveness in tonsilar mononuclear leukocytes and T cells of PPD(+) persons (SI was 20 and 14.1). PBMC and peripheral blood T cells of PPD(+) persons were also shown a significant responsiveness, but PPD(-) persons did not show. These results demonstrate that the 30 kDa antigen and IL-2 have a synergistic stimulatory property in mycobacteria sensitizing lymphocytes.

      • 제3분과 : 야생동물 ; 국립공원 산불통제구간내 야생동물 서식현황 분석 -지리산국립공원 노고단~피아골계곡을 중심으로-

        강병선 ( Byung Seon Kahng ),박기연 ( Ki Yeon Park ),김은창 ( Eun Chang Kim ),이재윤 ( Jae Yoon Lee ),지기선 ( Ki Seon Ji ),최형진 ( Hyung Jin Choi ),오현경 ( Hyun Kyung Oh ) 한국환경생태학회 2013 한국환경생태학회 학술대회지 Vol.2013 No.1

        우리나라 전 국토의 6.58%를 차지하고 있는 국립공원은 생태계 현황을 대표하는 지역으로 한국에 서식하는 생물종 39,150종 중 40%에 해당하는 15,727종이 서식하고 있다(국립공원관리공단, 2012). 특히 환경부에서 지정한 멸종위기종 221종 중에서 65%에 해당하는 144종이 서식하고 있어 인간의 간섭 및 개발압력으로부터 마지막 피난처의 중요한 역할 또한 수행하고 있다. 국립공원은 자연생태계와 자연 및 문화경관 등을 보전하고 지속가능한 이용을 도모함을 목적으로 하는 자연공원법에 의하여 지정되는 자연공원의 하나로서 자연생태계의 보전뿐만 아니라 지속가능한 이용 또한 고려되어야 한다. 즉, 생물종 서식처의 보존 뿐만 아니라 탐방객의 이용 또한 고려되어야 하며 이를 위해서는 생물종의 서식현황 분석은 반드시 선행되어야 할 과제이다. 그러나 생물종이 다양하고 서식처가 광범위하여 종의 전체적인 서식현황을 분석에는 많은 시간과 비용이 수반된다. 따라서 시간과 공간이 제한되는 산불조심기간 중 산불통제 구간을 대상으로 야생동물의 서식현황을 분석해 보고자 하였다. 아울러 구례군 지역에 서식하는 야생동물의 서식현황을 분석하여 보호지역 관리에 기초자료를 제공하고자 하였다. 월 1회 정기적으로 탐방로를 중심으로 야생동물의 식흔, 배설물 등 흔적을 2010년부터 2012년까지 최근 3년간 모니터링 하였으며, 모니터링 시 GPS 좌표 측점, 사진촬영, 주변환경조사 등을 병행하였다. 아울러 무인센서카메라를 10대 설치하여 실체를 확인하였으며, 조사된 자료는 GIS DB로 최근 3년간, 지리산국립공원 노고단~피아골계곡에서 조사된 야생동물 흔적은 124건으로 삵 59건, 담비 27건, 족제비 21건, 멧토끼 10건, 멧돼지 4건, 고라니 2건, 오소리 1건 등이었다. 이중 삵과 담비는 멸종위기종으로서 86건으로 발견종의 69%를 차지하고 있었다. 특히 봄과 가을철 산불통 제기간 중에는 월평균 19회 관찰되었는데 이는 다른 기간 평균 4회 보다 5배정도 많은 횟수로 탐방객의 출입이 제한되었을 때 위협요인이 감소됨으로서 서식여건이 보다 안정화되어 훨씬 많이 발견되고 있음을 알 수 있었다. 2010년부터 2012년 지리산국립공원 구례지역에서 조사된 야생동물 698건의 서식 분포특성을 분석한 결과 삵 286건, 담비 139건, 족제비 95건, 수달 53건, 오소리 30건, 멧돼지 30건, 멧토끼 29건, 너구리 16건, 고라니 13건, 노루 4건, 하늘다람쥐 3건 등이었다. 특히 멸종위기종인 삵, 담비, 수달, 하늘다람쥐 등이 481건으로 68%를 차지하고 있어 멸종위기 야생동물의 출현빈도가 매우 높음을 알 수 있었다. 최근 3년간 야생동물 서식현황을 분석한 결과 타기간 보다 산불방지기간에 출현빈도가 높아 탐방객의 출입에 따른 위협요인을 계량적으로 파악할 수 있었으며, 특히, 봄철 산불방지기간은 야생동물의 번식기라는 점에서 보다 안정된 서식처를 제공한다는 의의가 있을 수 있다. 또한 멸종위기종의 흔적이 전체종의 68%가 발견됨으로서 멸종위기종의 서식처를 제공하고 있음을 알 수 있었다. 향후 이러한 결과를 바탕으로 각 야생동물에 대한 서식처 분석과 더불어 이를 통한 관리방안이 수립될 필요성이 있다.

        개에서 이중 결찰법을 통한 동맥관 개존증의 완치 예

        윤헌영,정순욱,박희명,박철,정만복,김준영,한현정,황민,노병국,박상혁,장하영,박정윤 한국임상수의학회 2004 한국임상수의학회지 Vol.21 No.1

        A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

      • 머리염색이 인체에 미치는 영향

        윤형식,황성호,이현륭,김수호,박연석,권낙현,정호진,김동훈,노현주,홍성호,박병찬,이관,정해관 東國大學校醫學硏究所 2002 東國醫學 Vol.9 No.1

        일상생활에서 모발염색은 흔히 접할 수 있는 미용의 한 종류로 특히 젊은층을 중심으로 폭발적으로 유행하고 있다. 염색을 위항 사용하는 약제는 표백제와 발색제 등 각종 화학약품이 사용되고 있으나 이로 인한 건강장해에 대한 연구는 그리 많지 않다. 저자들은 염색이 인체의 모발건강에 미치는 영향을 파악하기 위하여 염색과 관련된 주관적 증상과 모발의 변화에 대한 실험적 연구를 시행하였다. 동국대학교 경주 캠퍼스 재학생 80명을 대상으로 설문조사를 시행하여 염색 유 ·무 및 염색 후에 경험한 증상에 대해 설문 조사하였고, 의과대학 재학생 46명을 대상으로 피부 반응 테스트를 실시하였다. 또한 염색 전후의 모발 탄성도를 측정하였고 모발의 상태를 파악하기 위해 전자 현미경검사를 실시하였다. 설문조사 결과 염색 전에 비하여 염색 후 안구혼탁, 안구건조, 시력저하, 발진 및 접촉성 피부염, 모발손상, 모근손상 등의 증상을 더 많이 경험한다고 호소하였다(p<0.05). 모발손상과 모근손상은 헤어드라이어 사용 빈도에 따라 증가하는 것으로 조사되었다(p<0.05). 피부반응검사에서 가려움증이 가장 많은 증상이었으며 이는 여성보다는 남성에서 높은 것으로 조사되었다. 염색 전후의 모발장력은 염색 전 134.5±10.37g, 염색 128.0±30.69g, 염색 이틀 후 112.5±19.69g으로 나타났다. 염색 전후의 모발의 전자현미경 케라틴 층이 현저히 감소하고 모발이 가늘어지는 차이를 보였다. 염색은 모발손상, 모발 케라틴 손상 및 모근 손상, 발진 및 접촉성 피부반응, 안구혼탁, 안구건조, 시력 저하를 유발한다. 따라서 염색약으로 인한 손상에 대한 주의와 예방이 필요하다고 생각한다. 예방대책으로 염색 전 피부테스트를 통한 적합성 여부를 판단하는 것이 필요하며 가급적 염색을 피하는 것이 좋을 것이다. 염색약에 발암물질이 포함되어있다는 보고도 있어 염색 제조사의 철저한 실험과 염색 물질의 선별이 염색으로 인한 부작용을 최소화하는데 중요한 역할을 할 것이다. Hair coloring has became one of the most popular cosmetic activities to younger generations during last decade. However, there are few studies on the health effect of widespread use of chemical dyes. This study was conducted to study the effects of hair coloring dye on hair and other systems. We conducted a questionnaire survey of 80 persons in Kyongju campus, Dongguk University. We have done open patch skin test on 46 medical students. We also conducted scanning electron microscopy to examine the hair strength and structure before and after hair coloring process. Injury of hair and hair bulb, contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity were the main symptoms complained after hair coloring (p<0.05). Injury of hair and hair bulb were increased by frequency of hair-dryer use(p<0.05). In open patch test, pruritus was complanined by more than half of the subjects. Mean strength of hairs before and after hair coloring was as follows; 134.5 (SD 10.37)g before hair coloring, 128.0 (SD 30.69)g immediately after hair coloring, and 112.5 (SD 19.69)g after two days. The scanning electron microscopic findings of hair surface before and after hair coloring showed decreased keratin layer and thinning of the hair. Hair coloring induces injury to hair, its keratin layer, and hair bulb as well as contact dermatitis, turbid eyes, xerophthalmia, and poor visual acuity. Therefore, we think that precaution is needed in use of hair coloring dye. To prevent complications induced by hair coloring dye, it is necessary, especially to those with allergy or skin disorders, to perform skin test before action and avoid hair coloring whenever possible. Longterm health effects of hairdye should be studied and manufacturing companies should try to minimize complications induced by hair coloring dye.

        Adipose sirtuin 6 drives macrophage polarization toward M2 through IL-4 production and maintains systemic insulin sensitivity in mice and humans

        Song, Mi-Young,Kim, Sang Hoon,Ryoo, Ga-Hee,Kim, Mi-Kyung,Cha, Hye-Na,Park, So-Young,Hwang, Hong Pil,Yu, Hee Chul,Bae, Eun Ju,Park, Byung-Hyun Nature Publishing Group UK 2019 Experimental and molecular medicine Vol.51 No.5

        <▼1><P>Adipose tissue inflammation is a reproducible feature of obesity and obesity-linked insulin resistance. Although sirtuin 6 (Sirt6) deficiency has previously been implicated in diet-induced obesity and systemic insulin resistance, the adipocyte-specific role of Sirt6 in the regulation of adipose tissue inflammation and systemic metabolic dysfunction in mice fed normal chow and in humans remains elusive. Here, using <I>Adipoq-Cre</I>-mediated adipocyte-specific Sirt6 knockout (aS6KO) mice, we explored whether adipocyte Sirt6 inhibits adipose tissue inflammation and its underlying mechanism. aS6KO mice fed normal chow gained more body weight and fat mass than wild-type mice and exhibited glucose intolerance and systemic insulin resistance. Measurement of plasma and tissue cytokines and flow cytometric analysis of adipose stromal vascular cells indicated a decrease in alternatively activated M2 macrophages in the adipose tissue of aS6KO mice. Mechanistically, Sirt6 regulated the expression of the canonical type 2 cytokine IL-4 by adipocytes in a cell autonomous manner, which in turn affects M2 macrophage polarization. Consistent with animal experimental data, the degree of obesity and insulin resistance demonstrated by the body mass index, fasting blood glucose and HbA1c correlated negatively with the expression of Sirt6 in human visceral fat tissues. Collectively, these results suggest that adipocyte Sirt6 regulates body weight gain and insulin sensitivity independent of diet, and the increased IL-4 production by Sirt6 and resultant M2 polarization of adipose tissue macrophages may attenuate proinflammatory responses in adipose tissue.</P></▼1><▼2><P><B>Obesity and diabetes: A control protein in fat</B></P><P>A protein in adipose tissue (composed of fat cells) helps protect against inflammation and the development of resistance to insulin that develops in obesity and can lead to type 2 diabetes. Researchers in South Korea, led by Eun Ju Bae at Woosuk University, Wanju, and Byung-Hyun Park at Chonbuk National University, Jeonju, investigated the role of Sirt6 in mice and in human adipose tissue. Deleting the mouse gene that codes for Sirt6 in adipocytes promoted the impaired response to insulin and associated increase in blood glucose levels that are two key aspects of diabetes. Changes in biochemical signaling pathways controlling immune cells called macrophages were implicated in these effects and suggest an anti-inflammatory role for Sirt6. Analysis of human adipose tissue supported these findings. The research will help understand how obesity promotes type 2 diabetes.</P></▼2>
