최종만(Choi Jong-Man) 학습자중심교과교육학회 2018 학습자중심교과교육연구 Vol.18 No.5
본 연구는 핸드볼 지도자의 리더십 유형이 선수 자기관리 및 팀 응집력에 미치는 영향을 알아봄으로써 핸드볼 지도자와 선수를 위한 기초자료를 제시하기 위한 목적으로 연구하였다. 연구목적을 달성하기 위하여 2017년 8∼11월 국내 전국규모 대회 에 참여한 중학교, 고등학교, 대학교 학생선수를 대상으로 편의표본추출법(Convenience Sampling Method)을 사용하여 총 446명(남자 학생선수: 309, 여자 학생선수: 137)의 설문지를 수집하였다. 자료분석은 SPSS24를 사용하여 빈도분석, 요인분석, 신뢰도분석, 상관관계분석, 다중회귀분석을 실시하였다. 연구결과는 핸드볼 지도자의 리더십 유형 중 훈련과 지시행동, 긍정적 보상행동, 민주적 행동, 사회적 지지행동은 선수의 자기관리 및 팀 응집력에 긍정적인 영향을 미쳤다. 즉, 지도자의 긍정적 리더십은 학생선수의 자기관리 뿐만 아니라 팀 응집력에 도움이 되어 경기력 향상을 높이는데 큰 역할을 할 것이다. The purpose of this study is to propose basic information for handball coaches and players by examining the influence of coaches’ leadership styles on players’ self-management and team cohesion. The convenience sampling method was used with middle school, high school, and college students who participated in nationwide athletic meetings during 2017, and questionnaires were collected from 446 participants (male:309, female: 137). Data analyses including frequency analysis, factor analysis, reliability analysis, correlation analysis, and multiple regression analysis were conducted using SPSS 24 software. The findings indicate that training, directive behavior, rewarding positive behavior, democratic behavior, and social support behavior have a positive impact on players’ self-management and team cohesion. In addition, positive leadership styles play a significant role in improving athletic performance by contributing not only to student players’ self-management but also to team cohesion.

본 연구는 수확시기가 수수×수수 교잡종 원형 곤포사일리지의 품질에 미치는 영향을 구명하기 위하여 천안에 위치한 국립축산과학원 자원개발부에서 수행되었다. 수수 × 수수 교잡종 SS405를 이용하여 숙기별 2회 (출수기 및 완숙기)에 걸쳐 수확을 하여 사일리지로 조제하였다. 숙기가 진행됨에 따라 수수 × 수수 교잡종원형 곤포사일리지의 조단백질은 증가하는 경향을 보였으나 NDF 및 ADF 함량 그리고 TDN 함량은 비슷한 수준을 유지하였다. 그리고 숙기별 in vitro 건물소화율도 비슷하였다. 숙기별 사일리지의 pH는 3.8~4.4을 유지하였으며, 출수기의 pH는 완숙기의 보다 높았다. 수수 × 수수 교잡종 원형 곤포사일리지의 수확시기가 늦어짐에 따라 젖산 함량은 증가하였으나 초산 함량은 감소하였다 (P<0.05). 그리고 출수기의 원형 곤포사일리지의 초산 함량은 트랜치 사일리지보다 증가되었다 (P<0.05). 완숙기에서는 제조방법에 따라 젖산과 초산 함량은 큰 차이를 보이지 않았다. 이상의 결과를 종합하여 볼 때 양질의 수수 × 수수 교잡종 원형곤포 사일리지 조제를 위해서는 출수기와 완숙기 사이에 수확하여 사일리지를 만드는 것이 사일리지 발효를 향상시킬 수 있다. This study was performed to investigate the effects of harvest stage of sorghum × sorghum hybrid (SSH) on nutritive values and quality of round baled SSH silage manufactured with SSH grown in paddy land of Department of Animal Resources Development, National Institute of Animal Science, RDA. SSH “SS405” was harvested at two different growth stages (heading and ripen stage) and ensiled at each harvest stages. Crude protein content of round baled SSH silage increased with delayed harvest maturity, but contents of ADF (acid detergent fiber), NDF (neutral detergent fiber), TDN (total digestible nutrient) and in vitro dry matter digestibility (IVDMD) was not changed. The pH in round baled SSH silage ranged from 3.8 to 4.4 at two different harvest stages, and pH in heading stage was higher than that of ripen stage. The content of lactic acid of round baled SSH silage increased with delayed harvest maturity (P<0.05), but the content of acetic acid decreased (P<0.05). The contents of lactic acid and acetic acid in ripen stage were not influenced by manufacture method of silage. The content of acetic acid in round baled SSH silage of heading stage increased as compared to that of trench SSH silage (P<0.05). Therefore, this study suggest that round baled SSH silage manufactured in both heading and ripen stage can improve the silage fermentation.

We got the following results from the 324 radiologic technologists as we surveyed their working condition by using the questionaire, who were working in the medical institutions (general hospitals and doctor's clinics) situated in the area of Seoul city, Kyung ki-do and Chung-chong-do since June to December 1985. 1. Their daily average working time was almost within 10 hours (in 93.9% of general hospitals, 66.1% of clinics). 2. About the numbers of holidays, 85.5% of general hospitals have one holiday per week,41.3% of clinics have one holiday per week or 38.5% of clinics have one holiday per two weeks. 3. Duty appointment of radiologic technologists in the department of radiology is taking charge of each part after serving for a certain part for some period (42.8%), taking charge of the special part continually or by turns in other working parts (35.3%). On the other hand in the clinics they took charge of all parts continually (53.2%) or by turns with their own situations. (30.3%). 4. Their daily working amount is too much in 51.6% of general hospitals or 45.8% of clinics. 5.

As the institute of education teaching radiologic technology in Korea, different from others, junior college is the only institute which has been managed for it as a two-year educational course for 27 years since 1963 when it was established for the first time in our country irrespective of the needs of the times. But according to the development of medical equipment, variety of medical skill, increase of medical demands now a days, the supply of radiologic technology in modern medicine not only makes it advance as an inevitable factor but also broadens the area of its business systematically. Therefore, we got the following results after we had considered the necessity to lengthen the term of education and searched for the most reasonable way. 1. The term of study of the radiologic technologists in junior college must be lengthened to 3 years from 2 or 3 years regulated in the law of education. 2. In three-year curriculum, the subjects like basic medical science, science and engineering and ultramodern science, etc., which are lated to the new radiologic science must be taught in the junior colleges, and hospital practice also must be a compulsory subject in curriculum. 3. As the school years becomes longer, a lot of programs to make the study effective must be searched, researched and propelled forward.

PURPOSE: This study aimed to determine the effect of active trunk training in the sitting position on balance and energy consumption in early stroke patients. METHODS: The subjects of this study were twenty four early stroke patients were recruited and randomly divided into two groups; experimental group (n=12) and control group (n=12). The subjects in the experimental group participated in active trunk training (20 min) and conventional physical therapy (20 min) five times a week for four weeks. The control group conducted general balance exercise (20 min) and conventional physical therapy (20 min) five times a week for four weeks. The outcomes were assessed using the Berg balance scale, Timed up and go test and energy cost and physiological cost index. RESULTS: Both groups showed a significant increase in their Berg balance scale and significant decrease in their Timed up and go test score, and energy cost and physiological cost index (p<.05). Compared to the control group, the experimental group experienced a greater increase in the Berg balance scale (p<.05) and a larger decrease in the timed up and go test score, and energy cost and physiological cost index (p<.05). CONCLUSION: We suggest that active trunk training in the sitting position may be effective in improving balance and energy consumption in early stroke patients. Thus, active trunk training is important for such patients. Further studies are needed to better understand the effectiveness of trunk training in early stroke patients.
