이경수,Lee, Gyeong-Su 국가핵융합연구소 2009 핵융합뉴스레터 Vol.41 No.-
세계적으로 부는 녹색 붐. 선진국들은 기후변화 대응과 경기회복을 동시에 꾀하기 위한 다양한 그린정책을 내놓고 있고 우리 정부도 저탄소 녹색성장이라는 타이틀로 참여하고 있다. 정부가 핵융합기술을 녹색기술에 포함시킨 현 상황에서 국가핵융합연구소가 해야 할 일은 무엇인지 이경수 소장의 이야기를 들어보았다.

공군 전투비행팀의 과업갈등, 관계갈등, 팀효능감 및 과업성과의 관계: 참여적 의사결정의 조절효과
이경수,임정인,박지영,손영우 한국산업및조직심리학회 2017 한국심리학회지 산업 및 조직 Vol.30 No.3
The purpose of the present study was to investigate integrally the relationships among task conflict, relationship conflict, team efficacy, and task performance of the Air Force Combat Flight Team. Also, the study illustrated whether participative decision-making moderated the relationship between task conflict and team efficacy, and the relationship between relationship conflict and team efficacy. Surveys and supervisor-rating performance data of 284 combat flight teams of two Air Force fighter pilots were collected for assessing the aforementioned relationships. Analyzing through structural equation modeling, the results indicated that task conflict was negatively related to team efficacy and task performance. Relationship conflict was negatively related to team efficacy whereas they were positively related with task performance. Moreover, team efficacy mediated the relationship between task conflict and task performance, and the relationship between relationship conflict and task performance. Furthermore, participative decision-making moderated the relationships of task conflict and relationship conflict with team efficacy such that these negative relationships were stronger when wingman pilot’s perception toward leader pilot’s participative decision-making was low. We discuss the implications of these results, study limitations, and practical suggestions for future research.

Improvement of testosterone deficiency by fermented Momordica charantia extracts in aging male rats
이경수,김현표,박현진,윤영걸 한국식품과학회 2021 Food Science and Biotechnology Vol.30 No.3
This study evaluated the efficacy of Momordicacharantia (MC; bitter melon) extracts against andropausesymptoms. We fermented MC with Lactobacillus plantarumand verified the ability of the fermented MC extracts(FMEs) to control testosterone deficiency by using agingmale rats as an animal model of andropause. FMEadministration considerably increased total and freetestosterone levels, muscle mass, forced swimming time,and total and motile sperm counts in aging male rats. Incontrast, sex hormone-binding globulin, retroperitoneal fat,serum cholesterol, and triglyceride levels were significantlyreduced in the treated groups compared to the non-treatedcontrol aging male rats. Furthermore, we observed thatFME enhanced the expression of testosterone biosynthesisrelatedgenes but reduced the expression of testosteronedegradation-related genes in a mouse Leydig cell line. These results suggest that FME has effective pharmacologicalactivities that increase and restore free testosteronelevels and that FME may be employed as a promisingnatural product for alleviating testosterone deficiencysyndrome.

The ossification of stapedial tendon is a rare disorder of middle ear that results in conductive hearing loss. It might be easily misdiagnosed as otosclerosis, and only exploratory tympanotomy can indicate cases where the mobility of stapes is not fixed or has increased. Cutting of the tendon results in nearly normal ossicular mobility and hearing improvement. A 41-year-old patient visited our clinic with slowly progressive hearing loss. Hearing evaluation revealed that he had a conductive hearing loss with intact tympanic membrane. The mobility of stapes was enhanced by cutting of the tendon through exploratory tympanotomy; hearing was improved thereafter.

Bleomycin 국소주사에 대한 Guinea pig 피부의 반응에 관한 연구
이경수,깁중환 대한피부과학회 1979 大韓皮膚科學會誌 Vol.17 No.5
Bleoxycin is known to have good therapeutic effect on verrucae, which has been used for varioua malignant turnors for its antimitatic effect RecentIy Kim & Kim, reported an exceIIent treatment method. of verrucae with Bleomycin using needle free dermojet. They poetulated that the excellent effcts were achievei thraugh infiltration of the ekin, in.cluding the affected epidermis, with Bleomycin which is not possible with other rnethods, It is therefore interesting to know the effects of Dermajet instilled Bleomycin an normal ekin. We selected guinea pigs for thia experirnent. Five albino guixim pigs, weighting about 500 Gm, were ueed. Bleomycin water ohxtion, 0.25mg/ml, 0.06ml for each chet was injected utilizing Dermojet on the back of a guinea pig after clipping. The injected sites and the contralateral sites were tiopsied a,fter vaxying length of time and histologia examinationa were made. The experiment was eoarranged that the biopsies for different experiment aitea celd be done on oxeittirnig. Six hours after the bleomycin injection, the epidermis becase shrunk and t@4e upper dermie showed aligbt inflammatory infiltration. After 10 hours. and also after 24 hours, a superficial ulceration and necrosis were noted and the dermal infiltration became progressively severer. After 2 days epithelization, had started and. the necrotic debris began to drop off. After 4 daya the epithelization was camplete. These findings were in sorne part similar to the findings observed in humans by Kirn and Kim in the treatment af verruca but th time sequenc was far faster in guinea pigs.
