본 연구는 제주도 주요 습지에 도래하는 도요ㆍ물떼새류의 지소적인 연구의 일환으로, 1998년 3월부터 2000년 2월까지 2년간 매월 2회씩, 1) 동부지역(하도리 양어장, 종달리 해안 및 성산포 양어장)과, 2)서부지역(용수리 저수지, 금등리 해안 및 대정읍 일과리 해안)으로 나누어 조사하였다. 조사기간 중 2개 지역에서 관찰된 도요ㆍ물떼새류는 총 45종 5,117개체였으며, 지역별로는 동부지역에서 40종 4,910개체, 서부지역에서 38종 927개체로 나타났다. 계절별로는 봄철 2,821개체, 가을철 1,229개체로 봄철에 도래하는 개체수가 가을철보다 많았다. 우점종은 제1차 조사기간인 봄철에는 민물도요 Calidris alpina 2,024개체(88.5%), 흰물떼새 Charadrius alexandrinus 84개체(3.7%), 흰목물떼새 Charadrius placidus 11개체(2.4%)의 순으로 나타났으며, 가을철에도 민물도요 384개체(82.9%), 흰물떼새 20개체(4.3%), 흰목물떼새 11개체(2.4%)의 순으로 나타났다. 제2차 조사기간에는 봄철에 좀도요 Calidria ruficollis 116개체(21.8%), 민물도요 67개체(12.6%), 청다리도요 Tringa nebularia 58개체(10.9%)의 순으로, 가을철에는 민물도요 191개체(24.9%), 노랑발도요 T. brevipes 156개체(20.4%), 삑삑도요 T. ochropus 104개체(13.6%)의 순으로 나타났다. 동부지역은 서부지역에 비하여 우점도는 높았으나, 종다양도와 균등도는 낮게 나타났다. 동부지역과 서부지역간의 유사도는 0.85였다. 본 연구를 통해 물꿩 Hydrophasianus chirurgus, 검은머리물떼새 Haematopus ostralegus, 바늘꼬리도요 Gallinago stenura, 흰꼬리좀도요 Calidrius temminckii 등 4종의 제주도 미기록종과, 검은머리물떼새, 흰목물떼새, 넓적부리도요 Eurynorhynchus pygmeus, 알락꼬리마도요 Numenius madagascariensis 등 3종의 환경부 지정 보호조류가 관찰되었다. This study was part of a continuous research project on the status of migrating shorebirds on major wetlands in Cheju Island. This study was conducted twice every month for two years, from March 1998 to February 2000. The investigated location are mainly two areas. The first census areas were Hado-ri fishfarm and the coast of Jongdal-ri in Kujaw-up and Sungsan-po fishfarm in Sungsan-up, all located in the eastern part of Cheju Island. The second census areas were Yongsu-ri reservoir and the coast of Kumdung-ri in Hangyoung-myon and the coast of Ilgwa-ri in Dejong-up, all located in the western part of Cheju Island. In total, 45 species consisting 5,117 individuals were observed during the census period. There were 40 species and 4,910 individuals in the eastern area, 38 species and 927 individuals in the western area. The number of individuals of shorebirds in the spring migratory season was greater than in the autumn. The dominant species researched during the first census period were 2,024 individuals of Calidrius alpina (88.5%), 84 individuals of Charadrius alexandrinus (3.7%), 59 individuals of Charadrius placidus (2.6%) in spring and 384 individuals of Calidrius alpina (82.9%), 20 individuals of Charadrius alexandrinus (4.3%), 11 individuals of Charadrius placidus (2.4%) in autumn. The dominant species researched during the second census period were 116 individuals of Calidrius ruficolis (21.8%), 67 individuals of Calidrius alpina (12.6%), 58 individuals of Tringa nebularia (10.9%) in spring and 191 individuals of Calidrius alpina (24.9%), 156 individuals of Tringa brebipes (20.4%), 104 individuals of Tringa ochropus (13.6%) in autumn. Dominance index were recorded better in the eastern area than the western area, but species diversity and evenness index were recorded lower in the eastern area than the western area. Similarity index were 0.85 between the eastern area and the western area. Hydrophasianus chirurgus, Haematopus ostralegus, Gallinago stenura and Calidrius temminuckii, which are observed during the census period are previously unrecorded species on Cheju Island. Rare and endangered species were observed such as Haematopus ostralegus, Charadrius placidus, Numenius madagascariensis, and Eurynorhynchus pygmeus.

애반딧불이의 유충상륙은 약 5.3일이 소요되었고 고치방을 만든 후 약 6.6일에 번데기로 변태하였다. 고치방의 크기는 길이 10.1 mm, 폭 4.7 mm, 벽두께 1.3 mm이었다. 번데기는 약 10.5일이 소요되었다. 성충이 되고 고치방 속에 약 6.8일 후에 출현하였다. 성충의 출현은 PM. 9시를 전후로 최대였고 PM. 10시에 감소하였다. 성충출현의 최적지온은 $23.4^{\circ}C$였다. 실내개체군(Lab-type)의 암컷 및 수컷과 야외개체군(Nat-type)의 수컷은 수명이 비슷하였고, Nat-type의 산란 수는 200${\sim}$400립 구간을 형성하였다. 단지, Nat-type의 암컷은 수명이 짧았으며, 산란 횟수와 산란 수는 적었다. 산란횟수에서 야외개체군은 2회와 실내개체군은 4회로 차이를 보이는 것은 야외개체군은 시료 채집 이전에 산란했을 가능성을 배제할 수 없다. The Luciola lateralis larva took 5.3 days from climbing on the land to the pupal cocoon formation. It took 6.6 days for a larva to eventually transform to a pupa after building a pupal cocoon. The size of pupal cocoon was 10.1 mm in length, 4.7 mm in width and its wall thickness was 1.3 mm. The mean pupal period was 10.5 days. The adult stayed 6.8 days in the pupal cocoon before escaping the cocoon. The peak adult emergence appeared around 9 p.m., and decreased after 10 p.m. The optimal soil temperature for emergence was $23.4^{\circ}C$. The female adult of the natural population (Nat-type) lived shorter, laid fewer eggs, and the oviposition frequency was fewer than that of the Lab-type individuals. However, a few individuals from the natural population laid 200-400 eggs. The less number of oviposition in the natural population may be due to the fact that the female adults might lay eggs before the collection for the experiment.

개선된 계단 배기 방법을 이용한 혈압 측정

In the automatic non-invasive blood pressure measurement device, the oscillometric method iswidely used. In the oscillometric method, the step-wise deflation has the advantage of the robustness for the motion artifacts than the linear deflation method. But it has the disadvantage of its longer measurement time because we need to detect two or more pulses in a certain cuff pressure step. In this study, we suggest the modified step-wise deflation method to overcome this limitation while maintaining the general concept of step-wise deflation. Using one valid pulse in each step and the deflating valve control during the diastolic period, the measurement time could be reduced. In order to verify the accuracy of the proposed algorithm, we compared the blood pressure values from the suggested method and the blood pressure values from the conventional auscultation method. The mean and standard deviation were -0.50${\pm}$5.3mmHg and 2.08${\pm}$4.75mmHg, for systolic and diastolic blood pressure respectively. The measurement time can be reduced up to the half of conventional step-wise deflation method.

Mitochondrial haplotype distribution and phylogenetic relationship of an endangered species Reeve's turtle (Mauremys reevesii) in East Asia

오홍식,박선미,한상현 국립중앙과학관 2017 Journal of Asia-Pacific Biodiversity Vol.10 No.1

This study was examined to reveal haplotype distribution and phylogenetic relationship using mitochondrial DNA CYTB gene sequences of Reeve’s turtle (Mauremys reevesii) of East Asia. CYTB sequences of Reeve’s turtles were divided into 6 haplotypes (Hap01–Hap06). Chinese turtles were found in Hap01, Hap02, Hap04, and Hap05, and Hap01 was the highest frequency of 85.0%. Korean Turtles were found in Hap01, Hap03, Hap04, and Hap05, and Hap03 was the highest frequency of 52.1%. Although there was no haplotype which includes only the CYTB sequence exclusive for Reeve’s turtles of Korea, since no CYTB sequence of China was found in Hap03, it would be possible that Hap03 turtles of Korea are separated from those of China. The haplotypes of Reeve’s turtles of East Asia were monophyletic, which indicated that they had been evolved from a single maternal lineage, but went through local evolution after geographical migration and isolation in East Asia.

혈압측정시 가압 단계에서 목표압력 및 측정 종료압력 추정

In blood pressure measurement, the oscillometric method detects and analyzes the pulse pressure oscillation while deflating the cuff around the arm. For its principle, one has to inflate cuff pressure above the subject's systolic pressure and deflate below the diastolic pressure. Most of the commercialized devices inflate until the fixed target pressure and deflate until the fixed completion pressure because there is no way to know the systolic and diastolic pressure before measurement. Too high target pressure makes stress to the subject and too low target pressure makes big error or long measurement time because of re-inflation. There are similar problems for inadequate completion pressure. In this study, we suggest new algorithm to set proper target and completion pressure for each subject by analyzing pressure waveform while inflating period. We compared our proposed method and auscultation method to see the errors of estimation. The differences between the two measurements were -4.02$\pm$4.80mmHg, -10.50$\pm$10.57mmHg and -0.78$\pm$5.l7mmHg for mean arterial pressure, systolic pressure and diastolic pressure respectively. Consequently, we could set the target pressure by 30 mmHg higher than our estimation and we could stop at 20mmHg lower than our estimated diastolic pressure. Using this method, we could reduce the measurement time.

본 연구는 한라산국립공원에 서식하고 있는 조류의 군집특성을 파악하기 위하여 2001년 4월부터 2002년 2월까지 조사되었다. 조사기간 동안 서식이 확인된 조류는 모두 72종 15,621개체였다. 관찰된 조류를 계절별 이동형으로 분류해보면, 텃새가 34종, 여름철새가 19종, 겨울철새가 11종이었으며 나머지 8종은 통과조류였다. 가장 많은 조류가 관찰된 서식지는 낙엽활엽수림지대로 69종 9,066개체였다. 한라산은 임연부에서 관목림에 걸쳐, 상록수림, 저지대의 혼효림, 낙엽활엽수림, 고지관목림 4가지형의 연속적인 식생의 다양성을 보여주고 있는데, 낙엽활엽수림대와 혼효림대에는 박새 Parus major, 직박구리 Ixos amaurotis, 큰부리까마귀 Corvus macrorhynchos가, 저지대의 혼효림대에는 큰부리까마귀, 직박구리, 참새 Passer mantanusm, 박새, 고지대의 관목림대에는 큰부리까마귀, 진박새 P. ater, 박새, 상록활엽수림대에는 큰부리까마귀, 직박구리, 멧비둘기 Streptopelia orientalis가 우점을 차지하고 있었다. 고도별로 각각의 종들이 해발고도별로 다른 분포양상을 보였는데, 이는 서식에 필요한 다양한 자원을 효과적으로 얻기 위한 적응수단인 것으로 보인다. The study conducted here is designed to clarify the characteristics of bird communities in Mt. Hall National Park, Jeju Island. For this study, 15,621 individuals among 72 species of birds are recorded during the period of April 2001 to February 2002. Thirty-four species were residents, nineteen summer visitors, eleven winter visitors and the others migrants. The maximum number of birds observed in the deciduous broad-leaved forest is 69 species and 9,066 individuals, respectively. Four types of groups of dominant species are noticed in the varying plant communities ranging from the forest edge to the scrub forest: Parus major, Ixos amaurotis and Corvus macrorhynchos in the deciduous broad-leaved forest and in the mixed (broad and needle) forest, C. macrorhynchos, I. amaurotis, Passer montanus and P. major in mixed forest of the lower montane zone, C. macrorhynchos, P. ater and P. major in the scrub forest and C. macrohychos, I. amaurotis and Streptopelia orientafis in an evergreen broad-leaved forest. There are different distributional patterns of birds in terms of the altitude. It is observed that there is difference in habitat preference or selection of each species, as well.

오홍식,강영국,남상호,Oh, Hong-Sik,Kang, Young-Kook,Nam, Sang-Ho 한국응용곤충학회 2009 한국응용곤충학회지 Vol.48 No.2

본 연구는 애반딧불이 유충의 상륙에 미치는 수온의 영향을 실내 외 조건에서 조사하였다. 실내 실험 결과에서 수온이 평균 19.3${\pm}$$0.3^{\circ}C$ 정온조건에서는 상륙 행동을 보이지 않았고, 20${\sim}$$22^{\circ}C$ 변온조건(평균 20.9${\pm}$$0.9^{\circ}C$)에서는 상륙을 시도하였지만 실제로 상륙은 이루어지지 않았다. 그러나 유충들은 평균 20.8${\pm}$$0.6^{\circ}C$ 정온조건에서는 가장 활발하게 유충의 상륙이 이루어졌다. 관찰 시점에 대한 조사는 실내 실험에서 유충의 상륙 빈도는 수온 20${\sim}$$21^{\circ}C$에서 전체의 63.6%로 높게 나타났다. 자연 서식처 실험에서 수온 19.8${\sim}$$21.7^{\circ}C$ 구간에서 상륙이 이루어졌으며, 상륙빈도수가 20${\sim}$$21^{\circ}C$에서 전체의 80.4%로 높게 나타났다. 서식처 실험에서는 실내 실험에서 유충의 상륙이 관찰되지 않았던 19${\sim}$$20^{\circ}C$구간에서도 유충의 상륙이 약간 관찰되었다. 실내 실험과 자연 서식처 실험의 조사일별에 대해 수온이 20${\sim}$$21^{\circ}C$에서 상륙빈도가 높게 나타났다. 실내 실험에서 유충의 상륙에서 성충의 출현까지 기간은 약 18일 소요되었으며 서식지 내에서 유충의 상륙부터 성충의 최초 출현 일과 최대 개체수 출현 일 사이의 기간 동안 기록된 수온의 구간은 19.6${\sim}$$21.8^{\circ}C$이었고 수온은 평균 20.4${\pm}$$2.3^{\circ}C$로 나타났다. 위의 결과를 보아 상륙에 요구되는 수온의 범위는 $20^{\circ}C$${\sim}$$21^{\circ}C$인 것으로 추정되며 가장 적정한 수온은 약 $21^{\circ}C$로 추정되었다. This study was conducted to investigate the relationship between the climbing up event of Luciola lateralis larvae and water temperature. In the laboratory condition, the larvae did not come out of water at constant temperature condition of 19.3${\pm}$$0.3^{\circ}C$ and tried to climb up at varying temperature condition of 20${\sim}$$22^{\circ}C$ (mean temperature 20.9${\pm}$$0.9^{\circ}C$) without success. However, they climbed up at constant temperature condition of 20.8${\pm}$$0.6^{\circ}C$. The frequency of the larval climbing up was highest as 63.6% at 20${\sim}$$21^{\circ}C$. The most larvae climbed up at approximately $21^{\circ}C$ of average daily water temperature, In the natural condition, the larvae climbed up at 19.8${\sim}$$21.7^{\circ}C$ and the frequency of the larval climbing up was high as 80.4% at 20${\sim}$$21^{\circ}C$. The larval climbing up was also little observed at 19${\sim}$$20^{\circ}C$ at which no larval climbing up was found in the laboratory experiment. No larvae attempted to climb up when water temperature was below $19^{\circ}C$ and above $22^{\circ}C$. It took 18 days from climbing up of larvae to appearance of adults. In its habitat, the range of water temperature required for larvae to climb up is assumed to be 19.6${\sim}$$21.8^{\circ}C$ and the most suitable water temperature may be 20.4${\pm}$$2.3^{\circ}C$. Therefore, the range of water temperature required for larvae to climb up is assumed to be 19.8${\sim}$$21.7^{\circ}C$, and the suitable water temperature range for larvae may be 20${\sim}$$21^{\circ}C$, and the most suitable temperature is thought to be $21^{\circ}C$.
