This study shows that genetic differentiation of Little egret in Korea is very low, probably due to its flight ability. Nevertheless, female site fidelity may cause the locally limited distribution of some rare mitochondrial CO1 and Cyt-b haplotypes. It is necessary to establish a protection and management plan of breeding sites where the rare haplotypes are found to sustain or increase the ecosystem diversity 본 연구에서 조사한 쇠백로 번식지간 유전적 분화 정도는 매우 낮으며, 그 주된 이유는 쇠백로의 이동성으로 생각된다. 그럼에도 불구하고 모계유전만을 하는 미토콘드리아 희귀 유전자형이 국지적으로 분포하는 것은 암컷의 유소성이 원인일 수도 있다. 이들이 서식하는 번식지의 보호관리방안의 마련은 유전자 다양성을 증대하며 궁극적으로 생태계 다양성을 높일 수 있을 것이다.
Wolbachia infection in the Loxoblemmus complex (Orthoptera: Gryllidae) in Korea
정길상,장이권,최재천,Hansu Choi 한국응용곤충학회 2012 Journal of Asia-Pacific Entomology Vol.15 No.4
The Wolbachia bacterium is one of the most prevalent intracellular symbionts of invertebrates, particularly insects. This bacterium induces four distinct reproductive anomalies such as cytoplasmic incompatibility,feminization, male killing, and parthenogenesis of its hosts. Here we report that three closely related cricket species, Loxoblemmus doenitzi, L. campestris, and L. equestris can become infected with Wolbachia. Based on the 16s rRNA sequences, all three species were single infections. However, Wolbachia infecting L. campestris showed diverse Wolbachia surface protein gene sequences resembling multiple infections. In addition, all Wolbachia strains in the three host species harbored the Wolbachia specific bacteriophage.

비만은 골밀도와 매우 밀접한 관계를 가지고 있다. 비만과 관련된 대사증후군과 신체활동의 관계에 대한보고는 있지만 운동에 따른 대사증후군 위험요인과 골밀도의 변화에 대한 관계는 아직 확실한 보고가 되지 않았다. 본 연구에서는 12주 동안의 걷기 운동이 비만여성의 대사증후군 위험요인과 골밀도에 어떠한 영향을 미치는지를 규명하는데 그 목적이 있다. 실험에 참가 동의한 피험자는 비만 중년여성으로 20명을 모집하여 10명씩 무선할당하여 운동군과 통제군으로 구분하였다. 운동훈련 사전과 사후에 대사증후군 위험요인과 골밀도를 측정하여 비교하였다. 운동프로그램은 하루 1시간씩 주3회로 최대심박수의 60-70%의 운동 강도로 실시하였다. 12주 동안의 걷기운동은 체중, HDL-C, speed of sound (SOS), 그리고 BMI를 통계적으로 유의하게 긍정적인 변화를 나타냈고 (p<.05), 수축기 혈압과 SOS는 양의 상관관계를 나타내었다 (r=.758, p<.05). 또한 운동 후 relative risk fracture (RRF)의 변화량은 중성지방의 변화량과 양의 상관관계를 나타내었다 (r=.636, p<.05). 본 연구에서는 비만개선을 위한 중저강도의 규칙적인 걷기운동이 체중감소와 함께 종골부위를 측정한 골밀도와 대사증후군 위험요인에 긍정적인 영향을 줄 수 있음을 확인할 수 있었다.
Wolbachia-induced reproductive anomalies and their future applications
정길상,서은호 한국곤충학회 2008 Entomological Research Vol.38 No.1
The Wolbachia bacterium is currently one of most prevalent endosymbionts of arthropods. The bacterium has drawn much attention because of its ability to induce reproductive anomalies, such as cytoplasmic incompatibility, feminization, male killing, and parthenogenesis, in various invertebrates. This review focuses on the basic biology of Wolbachia , its infection phenotypes, and its potential future applications.
정길상,Richard STOUTHAMER 한국곤충학회 2009 Entomological Research Vol.39 No.1
The Wolbachia bacterium is one of the most prevalent endosymbionts of arthropods. The bacterium is known to induce four distinct reproductive manipulations in its various hosts; namely, cytoplasmic incompatibility, feminization, male killing and parthenogenesis induction. The bacterial titer has been thought to have an important role in expression of these phenotypes. Although host eggs of the bacterium are the place where all of the manipulations take place, in most cases, they are not big enough to be subjected to mechanical disruption to extract genetic materials from them. Furthermore, DNA extraction protocols generally involve washing steps in which part of the DNA is lost. With the simple three step digestion protocol we developed, we were able to preserve the whole genome and measure the titer of Wolbachia in individual Trichogramma eggs by real-time quantitative polymerase chain reaction (PCR), which was comparable to the titer by visual observation.
스포츠 政策의 國際比較硏究 : 3個國의 스포츠振興法을 통하여
정길상,이강우 동국대학교 경주대학 1998 東國論集 Vol.17 No.1
Sports are said to be like a mirror which reflects society. Also, sports are of universal culture in that sports are performed on the basis of Internationally common rules and at the same time of culture characterized with a much national, publicly common feature which has the ability to form or build human relations between the members of society. Accordingly, an internationally comparative study on sport policies as a supportive system has a significant meaning in respect that it promotes understanding between countries as well as internalization. For that reason internationally comparative study on sport policies is considered to be very useful in that the performance of it can be really used as reference and it can be applied to the policies of a certain country. So far, internationally comparative study on sport policies seem to have been at a descriptive level of comparatively studying each of cases respectively, and such studies are at a level of describing similarities and dissimilarities between two countries. However, a comparative study is necessary in the future to develop the framework and scale in order to build the universal principle and general theory based on the similarities and dissimilarities of the sport policies of each nation. Also, in internationally comparative study on sport policies, there should be no a ethnocentrism.The culture of sport systems in any of races, peoples, nations has a special value. Accordingly, the attitude of such a kind study may improve sport programs or heighten the efficiency of them, thereby achieving new development of them.
