럭비풋보올選手의 適性(體格, 體力) 및 Try數 變化에 關한 調査硏究
이석주,최영근 경희대학교 체육과학연구소 1979 體育學論文集 Vol.7 No.-
For the purpose of finding out physical and character of rugby-football players, 50 players of highschool and 50 players of college have become the object of test standing height, body weight, 100m-running, 1500m-running, zigzag-run, kick, rugby-ball throwing through 1st, March, 1979 to 31th, March, 1979. According to the document of rugby-football association, trying-number of major goal-in of 19 years, from 1960 to 1978, and trying-number of all 228 games of spring-season-leagues and championship for list were accounted per 5 years. The physique of rugby-football players showed in average 174.0cm-standing height, 69.2kg-body weight and players of college are superior to them of highschool. Their record showed in average 13.3 seconds in 100m-running, 5 minutes and 57 seconds in 1500m-running and 10.3 seconds in zigzag-run with rugby-football. They marked 39.3m in kick, and threw rugby-football 7.7 times successfully, which show that there is no difference of highschool players and college players. But players of highschool and college marked a little superiority in test-record of 100m-running, zigzag-run, and kick. The trying-number did not change distinctively in 1960's, but, since 1970's, it has increased and trying-number of T.B. also has increased while it of F.W. decreased. The general trying-number is 258 in F.W. 57 in HB, and T.B-trying-number marked the highest record as marking the record 431.

본 논문은 샘플 채취 및 귀환 임무를 위한 탐사 로버의 필요기술 및 개발 과정에 관해 설명한다. 본 논문의 로버 개발은 미 항공우주국 주관의 Sample Return Robot Challenge 참가를 목표로 하여 대회 규정에 맞도록 진행하고 있다. 달 또는 행성임을 가정한 상황에서 진행되는 이 대회에서 탐사로버가 자율적으로 주행하고, 샘플을 탐지한 후 수집하여 귀환하기 위해 필요한 로버의 기계적 메커니즘과 센서/전자/통신 시스템 구성을 설명하고, 그 개발과정을 기술하였다. This paper introduces core technologies and development process of an exploration rover for sample return mission. The development purpose of the rover is similar to build a rover that can perform what NASA requires a robot to do participating in the Sample Return Robot Challenge: pre-learning sample to be found, searching for the target sample with autonomous navigation, and retrieving the sample to a goal location, which requires many techniques from various fields to work together. In order to suppose the rover operated at the space environment such as the Moon or the Mars, mechanical characteristics and sensor/electronic/communication systems are described in this paper.
First Record of Three Centropages Species (Copepoda: Calanoida: Centropagidae) in Korean Waters
이석주,Min Ho Seo,서호영 한국동물분류학회 2023 Animal Systematics, Evolution and Diversity Vol.39 No.1
Three species of the genus Centropages(C. calaninus, C. orsinii, and C. sinensis) were newly collected from Korean waters. The Korean specimens were consistent with previous descriptions, but differ in the following characteristics: in C. orsinii male right antennule with spine on dorsoposterior surface of each segment XIII and XIV; distal end of segment XIX with humplike process on dorsal surface; in C. calaninus female long spinelike process on second exopodal segment of leg 5 of reaching 1/2 length of terminal spine on third exopodal segment; in male, first endopodal segment of leg 5 without inner seta; left second exopodal segment serrated on distal margin; and in C. sinensis male distal spine of left second exopodal segment of leg 5 not fused with segment. In this study, key characters for species identification also were provided.
