본 연구는 스포츠용 탄력 압박 스타킹(Essential compression calf sleeve, SKINS, Australia)을 착용하고 최대 운동을 하였을 때, 하지 부종에 어떠한 효과가 있는지를 알아보고자 한다. 실험 대상자는 젊은 성인 남녀 30명으로(남자 15명, 여자15명) 근 골격계 및 심혈관계에 특이 병력이나 사고에 의한 외상 등이 없었으며, 규칙적으로 운동을 하는 자는 제외하였다. 대상자들의 신체적 특성을 파악하기 위해서 자동 신장계(BSM330, Biospace, Korea)를 사용하였다. 부종정도를 알기위해서 줄자로 운동 전후의 장딴지 근(종아리)의 둘레와 체성분 분석기(InBody 720, Biospace, Korea)를 사용하여 하지의 부종 수치를 측정하였다. 최대의 운동은 호흡가스 분석기와 연결된 트레이드밀(CPEX-1, IRS, Japan)을 사용하여 변형된 BRUCE Protocol TR-3에 따라 호흡 교환율(R) 값이 1.15이상 되거나 all-out 될 때까지 하였다. 실험 대상자들은 동일 집단으로 전이효과를 방지하기 위하여 일주일의 간격을 두고 스포츠 탄력 압박 스타킹 착용 유무에 따른 동일한 실험을 두 번 하였다. 측정은 최대 운동 전후의 장딴지 근(종아리)의 둘레와 부종 수치를 하였다. 스포츠용 탄력 압박 스타킹 착용 유무와 운동 전후를 비교하기 위하여 MANOVA(다변량 분산분석)를 사용하였고 유의수준은 .05로 설정하였다. 탄력 압박 스타킹을 착용한 상태에서 최대 운동 전후의 부종 정도를 측정한 결과 스타킹을 착용하지 않았을 때 운동 전후의 둘레가 유의하게 증가하였고(p<0.05), 스타킹을 착용 하였을 때 운동 전후의 둘레가 유의하게 증가하지 않았다(p>0.05). 부종 수치(세포외액/전체체액)는 탄력 압박 스타킹을 착용하였을 때 오른쪽 다리는 유의하지 않게 감소하였고(p>0.05), 왼쪽 다리는 유의하게 감소하였다(p>0.05). 탄력 압박 스타킹을 착용하고 운동할 경우 하지의 부종 경감에 어느 정도 효과가 있다고 사료된다.

This study was conducted to distinguish adult morphology of the giant water bug (Lethocerus deyrollei) between over-wintered (OLD) and new-born (NEW) populations using materials collected from Gyodong island in Gyeonggi-do, Korea, as well as individuals reared in the laboratory (LAB population) as a control. As a result, no fundamental differences were found in external body structure between OLD, NEW, and LAB populations. However, marginal area of basal procoxa in ventral prothorax and jointed part of forefemur and foretibia were greatly worn in the OLD population. Mid-claws were shorter than 0.5 times the length of the 2nd mid-tarsus; the membranous margin of hemelytra was greatly worn; and hairs of the 5th abdominal tergum were greatly reduced in the OLD population.

Objective: The purpose of this study was to investigate the relationship between menarche and cervical vertebral maturation. Methods: Lateral cephalograms of 67 young korean girls within the range of 1 year before or after their menarche were gathered. The concavity of the cervical vertebrae base and the ratio of the base length to the 3rd and 4th cervical vertebrae anterior height were measured and analyzed. Results: The mean measured values were as follows, concavity of the 3rd cervical vertebrae base: 1.27(${\pm}0.18$) mm, concavity of the 4th cervical vertebrae base: 1.06(${\pm}0.15$) mm, ratio of the base length to the 3rd cervical vertebrae anterior height: 0.73(${\pm}0.06$) and ratio of the base length to the 4th cervical vertebrae anterior height: 0.70(${\pm}0.05$). There was a significant increase in the ratio of the base length to the 3rd vertebrae anterior height and the base concavity of the 3rd and 4th cervical vertebrae during the period of 1 year before to 1 year after their menarche. Conclusions: These characteristics of the 3rd and 4th cervical vertebrae on the lateral cephalogram can provide useful clues on evaluating the growth stage.

1935년부터 55년까지 세계 대전에 휘말렸던 일본의 과학자들은 견디기 어려운 시련을 극복하고 전후에 2명의 노벨물리학 수상자를 배출했다. 1949년에 유가와 히데키가, 1965년엔 도모나가 신이치로가 그 주인공이다. 이처럼 가장 어려웠던 폐허 속에서도 일본이 이론물리학의 창조적 성과를 올린 배경은 무엇이었을까?

CTP장비의 국내 보급속도가 제트기류를 탈 전망이다. 지난 KIPES2002(국제인쇄산업전시회)를 전후해 CTP장비 보급업체가 크게 늘어나고 있기 때문이다. 프리프레스장비 공급업체에 따르면 KIPES를 전후해 CTP장비에 대한 상담건수가 날로 증가하고 있을 뿐만 아니라 총 9대를 계약한 것으로 조사돼 앞으로 더욱 늘어날 것으로 기대되고 있다.

1954년 5월 정음사에서 간행된 정비석의 "자유부인"은 한국출판사상 '전전'과 '전후'의 분기점에 놓여 있는 책이라 할 수 있다. 베스트 셀러로서의 화제성이나 출간 서점에서도 그렇지만, '자유부인'이라는 말 자체가 50년대 초반 전후 한국사회의 실상을 상징하는 대명사쯤으로 치부돼 왔다는 점에서 더욱 그렇다.

트랙터용 전후진 파워시프트 변속기의 개발을 위해서는 사용조건, 설계 조건에 맞는 유압제어 시스템 설계가 중요하며, 이를 위해서는 해석적 방법을 통하여 변속시 발생하는 클러치 흡수동력, 입출력 토크, 가속도와 저크 등에 대한 고찰이 필요하다고 판단된다.

The purpose of this study is to investigate the differences in recognition for foundation before and after foundation education for preliminary senior founder' demographic characteristics, and to verify the effects of the characteristics on the foundation interest and foundation confidence. For this, questionnaire survey was carried out for 103 preliminary senior founders who participated in the foundation education program implemented by government. The statistical significance was verified with SPSS 18.0 program. On the basis of empirical study results, the main results were withdrawn as follows. First, there was a significant difference in foundation interest between before and after foundation education. Second, there was no significant difference in foundation interest with foundation motivation at before and after foundation education. Third, there was no significant difference in foundation confidence between before and after foundation education. Fourth, there was no significant difference in foundation confidence with foundation motivation at before and after foundation education. In conclusion, this study recommends an alternative for education curriculum development and operation for improving the actual performance of the curriculums targeting the senior generation through reliable research.

Purpose: This study compared the SLAP lesions caused by a sports-induced injury with those caused by a non-sports-induced injury. Materials and Methods: The study was performed on 54 patients who had undergone arthroscopic surgery for a SLAP lesion. There were 21 sports-induced-injury patients (group I) and 36 non-sports-induced injury patients (group II). The mean age of the men was 36 years and that of the women was 48 years. In both groups, the frequency of a concomitant injury and the clinical outcomes at the last follow-up was evaluated using the UCLA score, Rowe score, and the ASES score. Results: According to their injury mechanism, , there were 14 cases (67%) of repeated microtrauma injury in group I and 25 cases (75%) of compression injury type in group II. As a concomitant pathology, there was 11 cases of shoulder instability and 5 cases of a rotator cuff tear in group I, and 23 cases of rotator cuff tears and 14 cases of shoulder instability in group II. At the last follow up, group I showed slightly better clinical satisfaction (P>0.05). Conclusion: The possibility of a SLAP lesion accompanying other diseases is high. Therefore, an accurate assessment of concomitant injury lesions before surgery is important for the treatment outcome.
