        제주시험림 한남 지역의 조류 군집 특성

        박찬열 ( Chan Ryul Park ),김은미 ( Eun Mi Kim ),강창완 ( Chang Wan Kang ) 한국환경생태학회 2011 한국환경생태학회지 Vol.25 No.6

        본 연구는 제주시험림 한남지역에서 2006년 11월부터 2007년 9월까지 매월 3일 연속으로 11개월 동안 선조사법에 의한 2개 지역과 정점조사법에 의한 5개 지역을 정하여 이동성, 둥지 길드, 출현비율의 군집 분석을 통하여 조류 군집의 특성을 살펴보았다. 총 58종의 조류를 확인하였으며, 조류를 이동성(migration habit)에 따라 나누면, 텃새 24종, 여름철새 8종, 겨울철새 10종, 나그네새 16종이었다. 대개 육지에서는 여름철새의 종 수가 높지만, 조사지역에서 나그네새 종수가 더 많은 것으로 나타났다. 또한, 월별 출현종의 관찰비율을 군집 분석한 결과, 11월부터 2월의 모둠, 3월~7월의 모둠으로 나누어져 계절성을 보였으나, 월별 종 수 변화는 육지에서 나타나는 계절 변동이 없었다. 번식기와 비번식기에 종 구성은 변화하지만, 전체 종수는 계절 변동을 나타내지 않았다. 이는 나그네새 등 이동성 조류가 제주시 험림을 다수 방문하는 것을 나타낸다. 산림성 조류에게 둥지를 제공하는 딱따구리류는 본 조사지에서는 큰오색딱다구 리 1종으로 육지의 5종과 차이를 나타낸다. 둥지 길드는 덤불 및 지면에서 둥지를 튼 새는 9종, 숲지붕층 8종, 나무구멍 7종, 인가에서 번식하는 1종이 기록되었다. 조사지에서 큰오색딱다구리는 박새류, 흰눈썹황금새, 호반새의 둥지를 제공하는 핵심종(keystone species)으로서 이 종을 보호하기 위한 산림시업을 고려해야 할 것으로 판단된다. This study was conducted to understand the characteristics of bird community, migration, nesting guild,ordination analysis of observed frequency of birds at Jeju Experimental Forests (JEFs) from November 2006 to September 2007 with surveys of two areas by line transect methods and point-count methods at five areas for three consecutive days in each month. Among observed 58 species could be classified into the 24 residents, 9 summer visitors, 9 winter visitors and 16 passage migrants according to migration habit. In species composition, passage migrants are dominant birds at study areas whereas summer and winter visitors are most dominant birds at mainland`s forests. We could divide two groups of bird community in the view of monthly species composition, one is November to February group, the other March to July group by ordination analysis. Number of species did not show seasonal fluctuation which is common pattern of bird community in mainland. This pattern reflects that species composition can change during breeding and non-breeding periods, but overall number of species did not change. This can be related with the high use of passage migrants at study area, also suggests that the JEFs can be highly utilized as stopover sites during migration. At mainland``s forests, we can observe about five species of woodpeckers, however we just observed the only one species of White-backed Woodpeckers (Dendrocopos leucotos) at study areas. In the view of nesting guild, breeding birds can be grouped into the 9 bush-& ground nesters, 8 canopy nesters, 7 hole nesters and one house nesters. Among hole nesters, we can observe only one species of primary cavity nesters White-backed woodpecker, and the five secondary cavity nesters, that is three species of tits, tricolor flycatchers (Ficedula zanthopygia) and ruddy kingfishers (Halcyon coromanda). Therefore, White-backed woodpeckers can be regarded as a keystone species and forest practice should consider the careful conservation of this species.

        Inhibitory Effect of Clavicepitaceae on Serotonin Release out of Human Platelets and Human Platelet Aggregation

        박화진,--,--,--,--,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2004 Journal of biomedical laboratory sciences Vol.10 No.1

        We have investigated the effects of hypha-water extracts (HWE), fruit body-water extracts (FWE) and cordycepin from Cordyceps militaris on serotonin release out of human platelets and human platelet aggregation. HWE and FWE inhibited the release of [^(3)H]-serotonin from human platelet stimulated by thrombin (2 U/ml) or collagen (20 ㎍/ml) in a dose-dependent manner. Furthermore, cordycepin, a major component of Cordyceps militaris, inhibited the human platelet aggregation induced by collagen (10 ㎍/ml) in a dose-dependent manner. These results suggest that cordycepin containing in HWE and FWE may inhibit the serotonin release by suppressing the collagen-induced human platelet aggregation. Accordingly, our data demonstrate that HWE and FWE containing much cordycepin might have antithrombotic and antimigrainous functions.

        홍삼류의 섭취가 비만과 혈중 지질의 상호관계에 미치는 영향

        박화진,이정희,이소진,함혜선,조현정,임창률,유영빈,박기현 대한의생명과학회 2000 Journal of biomedical laboratory sciences Vol.6 No.4

        비만은 동맥경화의 위험인자로서 혈중에 triglyceride의 농도를 종가시키고, 상대적으로 HDL-Cholesterol의 농도를 감소시킴과 동시에 수축기 혈압을 상승시킨다. 본 연구에서 홍삼제품류를 4년 또는 5년 동안 복용해 온 건강한 사람 (ginseng군)과 홍삼제품을 복용하지 않은 건강한 사람 (control군)을 대상으로 하여 신체 계측치로부터 비만지수를 구하고 이것과 혈중의 triglyceride (TG)농도, TG/HDL-Cholesterol ratio 및 수축기 혈압과의 상호관계를 연구한 바, ginseng군에서는 대조군에 비해 혈중의 TG 농도가 일정하게 유지되었고, TG/HDL-Cholesterol ratio 및 수축기 혈압도 일정하게 유지되었다. 이러한 현상은 ginseng군에서 기호품으로 alcohol을 섭취하거나, 흡연을 한 경우에도 상관없이 일정하게 유지 되었다. 이 결과는 홍삼제품류를 장기 복용하면 비만의 저하 및 고혈압 또는 동맥경화의 위험인자가 억제될 수 있고, 결론적으로 비만, 고혈압 및 동맥경화를 예방할 수 있을 것으로 추정한다. Obesity is the risk fcactor of atherosclerosis and not only increases triglyceride concentration in blood but also decreases relatively the ratio of TG to HDL-Cholesterol in blood. In case of obesity, systolic blood pressure is also increased in responding the increase of TG in blood. Index of obesity in red ginseng-taking group (ginseng group) was lower as compared with non-red ginseng-taking group (control group). The TG concentration, the ratio of triglyceride to HDL-cholesterol in blood and systolic blood pressure were decreased in the subjects of ginseng group compared with that in control group. It is inferred that long-term intake of ginseng products may help to prevent the risk of atherosclerosis and obesity.

        한국대학생의 음주양태와 생물정신사회적 요인의 상호관계

        이창인,김학렬,박동건 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.5

        연구목적 및 방법 : 본 연구는 한국 남자 대학생의 음주양태와 생물학적, 심리사회적 요소의 연관성을 알아보기 위해, 약4개월에 걸쳐 조선대학교 의과대학 의학과 학생 750명중 예비조사 결과 선정된 94명의 남학생을 대상으로 음주양태에 대한 설문지, 생활사건척도, 사회지지척도, 내-외 통제척도, 성격차원검사, 상태-특성 불안척도, 간이정신진단검사, 에탄올 삽포검사를 통해 다음의 결과를 얻었다. 결 과 : 1) 소량음주군과 과량음주군(이후 두 군으로 칭함)의 가족력 비교결과 소량음주군의 가족에서 음주후 급성 신체반응 민감자가 많았다(p〈.005). 2) 소량음주군에서 음주후 급성 신체반응이 많았으며(p〈.005). 과량음주군에서 음주후 심리적 유쾌감이 높았으며(p〈.005). 심리적 불쾌감은 차이가 없었다. 3) 성격, 심리, 환경적 특성비교에서 과량음주군이 성격차원검사의 외향성 척도가 높고(p〈.01). 사회 지지척도상 물질적 지지도가 높았다(p〈.01). 4) 에탄올 삽포검사상 15분, 30분, 60분후 모두 소량음주군의 양성반응율이 높았다(p 〈.005). 5) 한국형 알코올 사용척도(AUI) 하위요인을 비교한 결과 요인 1, 2, 4는 α=0.005 수준에서, 요인 3는 α=0.01 수준에서 과량음주군이 높았다. 6) 두 군의 음주양태 비교에서 소량음주군은 유사 비음주자. 숭화형 음주자가 많았고, 과량음주군은 일과성 사교음주자, 자제형 사교음주자, 습관적 과음자, 충동적 폭음자가 많았다(p〈.005). 두 군의 음주 양상의 차이는 과량음주군은 음주 의존도, 음주기간, 일일 음주성향, 음주선호, 술의 돗수, 막걸리, 소주 및 맥주의 평균 주량과 최대 주량, 맥주의 한 모금에 마시는 양은 α=0.01 수준에서 높으며, 소량음주자는 술을 마시는 두 모금사이의 시간이 유의하게 길었다(p〈.005). 7) 두 군의 사회인구학적 변인의 비교에서 과량음주군의 흡연율이 상대적으로 높았고(p〈.01), 가족들의 주거지를 보면 과량음주군은 대도시 출신이 많은 반면 소량음주군은 시골 출신이 많았으며(p〈.05), 동거 가족수는 소량음주군이 많은 편이었다(p〈.05). 그외의 다른 사회인구학적인 변인에서 과량음주군은 부모의 학력이 모두 높았고(p〈.05), 부모의 부부사이가 나쁜 편이었다(p〈.05). 결 론 : 알코올중독의 원인론과 그 특성에 대한 이해를 돕기 위해 비교적 균일하며 병적인 음주행태가 시작되는 대학생 집단에서 과량음주군과 소량음주군으로 나누어 비교했는데, 현저한 차이를 보이는 것은 ALDH 활성도 결핍과 강력히 연관된 것으로 추정되는 급성 신체(홍조)반응과 에탄올 삽포검사의 양성율의 차이였고 심리사회적인 측면은 다소의 차이가 있었으나 구체적인 해석에 어려움이 있었다. Objects and Methods : In order to evaluate the relationships between drinking habits and biological and psychosocial characteristics, the authors administrated the questionnaires about drinking patterns and acute physiological and psychological responses after drinking, several psychological scales and ethanol patch test to 94 male medical students in Chosun University. Results : 1) Low consumer group had significantly more severe physiological respondents after drinking in family members than high consumer group(p<0.05). 2) Low consumer group has significantly more severe acute physiological responses(p<0.005) and high consumer group revealed more positive psychological responses after drinking(p<0.05). But there was no difference in the degree of negative psychological responses between two group. 3) High consumer group had significantly more extroversion tendency(p<0.1) and received more financial support from family than low consumer group(p<0.1). 4) In the results of ethanol patch test, low consumer group showed more positive skin reaction in three test occasions than high consumer group (p<0.005). 5) Also the high consumer group revealed higher scores in factor 1, 2, 4(α=0.005), and 3(α=0.01) in comparison of factors of Korean Alcohol Use Inventory. 6) In comparison of drinking habits, low consumer group revealed higher incidence of nearly non-drinkers and sublimatory drinkers. But there were more casual social drinkers, sel-controlled social drinkers, impulsive-binge drinkers, and habitual-excessive drinkers in high consumer group(p<0.05). And in drinking patterns, the items of dependence and duration of drinking, daily drinking disposition, preferential beverage, average and maximum drinking amount of each liquor, and magnitude of sips taken were higher in high consumer group. Only one item of interval between sips was longer in low consumer group(o<.005). 7) In comparison of sociodemographic variables, there were more students who were smokers(p<0.1), from larger cities and small family(P<0.5), and whose parents were well educated(P<0.5) but had worse marital relationship(P<0.5) in high consumer group. Conclusion : For better explanation of the etiology and characteristics of alcoholism, we investigated the differences in various aspects between low alcohol consumers and high alcohol consumer in college students. The most evident differences lied in the degree of acute physiological reaction and positive rates of ethanol patch test that strongly suggested the relations with the activity of ALDH. Some differences in psychosocial aspects between two groups were noticed but could not appropriately be explained at this time.

      • Brucella abortus 국내 분리주의 Heat Shock Protein 암호 groE 유전자의 염기서열 분석과 발현

        김태용,김지영,장경수,김명철,박창식,한홍율,전무형 충남대학교 형질전환복제돼지연구센터 2007 논문집 Vol. No.10

        GroE that is a heat shock protein composed of GroEL and GroES is known as an immunodominant target of both the humoral and cellular immune responses in bovine brucellosis. This study was carried out to characterize groE gene encoding heat shock proteins of B. abortus isolated in Korea and to evaluate the immunogenicity of the GroE protein expressed in E. coli system. In PCR the specific signals with the size of 2,077 bp were detected in five strains isolated from the mammary lymphnodes of the dairy cattle that were serologically positive and the reference strains. In comparison of the sequences of nucleotides and amino acids among the strains, GroES showed 100% identity in both sequences. GroEL was evaluated 99.0∼99.9% in nucleotides and 98.0∼100% homology in amino acids. The groE gene including groES and groEL was inserted into pET29a vector and constructed pET29a-GroE recombinant plasmids. The inserted groE was confirmed by digestion with Ncol and EcoRl endonucleases and nucleotide sequencing. E. coli BL (DE3) was transformed with pET29a-GroE, named as E. coli BL (DE3)/pET29a-GroE. In SDS-PAGE, it was evident that the recombinant plasmid effectively expressed the polypeptides for GroES (10 kDa) and GroEL (60 kDa) in 0.5, and 2 hours after IPTG induction. The immuno-reactivity of the expressed proteins were proved in mouse inoculation and Western blot analysis.

        This study was carried out to determine therapeutic the effect of ozonated water therapy on bovine pododermatitis. In addition, bactericidal effect of ozonated water on etiological agent of bovine pododermatitis was examined. The pathohistological examination for the pododermatitis, according to application with ozonated water and ozone ointment was investigated. Thirty healthy cattle were divided two groups(each of 15) : control group (povidone group), treatment group (ozone solution group). Various parameters were evaluated in terms of the lameness score, swelling score, lesion score, WBC count, neutrophil count, pathohistological finding, and antimicrobial action. The decrease of lameness and lesion score were shown in hoof lesions on 14 days after application of ozonated water. Significant decrease of swelling was shown in hoof lesions on 14 days 1 Corresponding author after application of ozonated water(p < 0.01). In hematological findings, WBC count revealed values within normal range. The number of neutrophils was slightly higher than that of normal, however, this was improved on 14 days after application of ozonated water. In pathohistological findings, recovery was rapid macroscopically and microscopically in the treatment with ozonated water on the hoof lesions and ozonated water was effective. In antimicobial action, bactericidal effect was observed in treatment with ozonated water on the hoof lesions and ozonated water was effective.

        이경태,송백용,양기원,김나민,김장렬,박성률 대한스포츠의학회 2000 대한스포츠의학회지 Vol.18 No.2

        Purpose : We evaluated and analyze the injury of the professional soccer player which would be helpful data for prevention of injury. Materials and Methods : Thirty-four professional soccer players were followed prospectively for one year and obtained injury exposure rate. We divided the injuries according to the position of the players incurred average 10 injuries for one year and the injury exposure rate was 2.9/1000hours, mostly strains and sprains of the lowre extremities. According to the player's position, the injured area and injury mechanism were different, Defence-Fielder and Mid-Fielder were more vulnerable to injury, 43% and 41.8% respectively, and mainly thigh and ankle injury. But Forward injury was less frequent and mainly leg and knee injury. In Goal-Keeper, neck and upper extremity injury was pre-dominant. Acute traumatic injury was 93% and recovery time was average on day, however, chronic overuse injury was less frequent but much longer time was required for recovery. Conclusion : The overuse injury is preventable by improving the environment and training program so that more attention is required.
