본 연구는 기업 환경의 불확실성이 증가되고 있는 시점에서 변혁적 리더십과 셀프리더십이 팀 성과에 어떠한 영향을 미치는지를 분석함으로써 팀제의 효용성과 리더십의 중요성에 대한 시사점을 제시하는데 그 목적이 있다. 조직구성원 간에는 교환관계 질을 형성한다는 LMX이론과 사회교환이론 및 경영환경에 적합한 리더십을 발휘해야 한다는 상황이론을 본 연구의 이론적 배경으로 하고 있다. 국내 공기업 9개사를 대상으로 총 166개 팀 880명의 유효 데이터를 활용하여 SPSS 20.0을 이용 회귀분석으로 연구가설을 증명하였다. 연구결과 팀장의 변혁적 리더십은 팀 성과에 긍정적 영향을 미치며, 셀프리더십의 행위전략과 인지전략은 팀장의 변혁적 리더십과 팀 성과 간의 관계를 유의하게 조절하는 것으로 나타남으로써 당초 설정된 연구가설을 모두 채택하게 되었다. 특이한 점은 셀프리더십이 낮은 집단에서 그 효과는 더욱 강하게 나타났다. 본 연구결과가 함의한 바는 팀제 조직에서 팀의 관리자가 셀프리더십이 상대적으로 낮은 집단의 구성원들에게 관심을 갖고 실천할 수 있는 목표를 부여하여 구성원 스스로가 동기부여 될 수 있도록 배려한다면 그렇지 않은 경우와 비교해서 팀 성과는 뚜렷이 향상된다는 것이다.

BACKGROUND/OBJECTIVES: Numerous researches have studied the association between sugar intake and obesity of children in many countries. This study was undertaken to investigate the association between beverage intake and obesity of children by reviewing a database for total sugar contents established in all foods and presented in a nutrition survey by the Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS: Data of 1,520 children aged 6-11 years in the 6th KNHANES (2013-2015) were analyzed for this study. A database for total sugar intake comprises the total sugar contents of all foods included in the results of a nutrition survey using the 24-hour recall method of 6th KNHANES. Beverages were categorized into carbonated beverages, fruit & vegetable drinks, other drinks, tea, and coffee. RESULTS: The average daily beverage intake of all children was 131.75 g/day, and the average daily total sugar intake in beverages was 13.76 g/day. Carbonated beverages had the highest intake rate (58.85 g/day) and also ranked highest for sugar intake (6.36 g/day). After adjusting for confounding variables, the odds ratio for obesity in children with beverage intake of ${\geq}200mL/day$ significantly increased by 1.83 times (95% CI, 1.11-3.00) as compared to children with beverage intake of < 200 mL/day. Also, a significant increase was observed in the odds ratio for obesity in total children (2.41 times; 95% CI, 1.35-4.33) and boys (3.15 times; 95% CI, 1.53-6.49) with carbonated beverage intake of ${\geq}200mL/day$ when compared with children who consumed < 200 mL/day. CONCLUSION: A positive association is observed between beverage intake and obesity in Korean children. In particular, an intake of carbonated beverages has a positive correlation with childhood obesity in boys. This study can therefore be used as scientific evidence for reducing sugar, and for the continuous management and research on beverages.

Objectives: The purpose of this study was to examine the association between participation in physical activities (PA) and subjective well-being. Methods: We analyzed the data from Korean Youth Risk Behavior Web-based Survey, 2013 containing 36,655 and 35,780 for male and female students respectively. Study variables included PA, participation in physical education class, participation in team sports and subjective well-being. Control variables were school type, socio-economic status, level of parent education, living with parent, academic performance, delinquent behaviors, depression and perceived health. For this study, descriptive analysis, Chi-square test, and multivariate logistic regression analysis were performed. Results: Among boys, after adjusting for control variables, PA (past 7 days 0 time reference group vs. over 4 times: OR 1.306), physical education class (past 7 days 0 time reference group vs. over 3 times: OR 1.140), and team sports (no team reference group vs. 2 team: OR 1.206) were associated with subjective well-being. Among girls, control variables were adjusted. PA (past 7 days 0 time reference group vs over 4 times: OR 1.244), physical education class (past 7 days 0 time reference group vs. over 3 times: OR 1.161), and team sports (no team reference group vs. 2 team: OR 1.181) were associated with subjective well-being. Conclusions: Participation in physical activities may help adolescent promote their life satisfaction. Thus, education experts should develop various exercise curriculums to encourage participation in physical activities.

This study is to consider hypotheses with integral view on the respect of creative thinking. Subjects of this study are Korean students in the 5th grade who participated in the Field Trip Contest of the second Korean Youth Science Festival, an openended inquiry investigation. Objectives of this study are as follows: 1) to measure the inquiry level of the Field Trip Contest activity 2) to find how many hypotheses were made on different types in the inquiry investigation 3) to measure the quality level of hypotheses made in the scientific inquiry investigation 4) to find out the correlation between the 1st and 2nd hypotheses and the final activity score in the two staged scientific investigation In the consequence of it, inquiry level of the Field Trip Contest was very high with good activity topics and openended way of investigation. Hypotheses were made in the prediction, plan, and conclusion parts in the field trip activity report. They used hypothesis-as-prediction typed statements(3.41/team) more than hypothesis-as-explanation(1.28/team) and descriptive hypothesis(0.03/team) types. Content-related hypothesis(5.03/team) and process-related hypothesis(6.16/team) were usually coupled each other. Most of them had difficulties in hypothesis-from-evidence(0.31/team, 10/32 teams) in the comparison of hypothesis-from-simple conjecture(10.62/team). The quality level of content-related hypotheses(0.74point/statement) and process-related hypotheses(1.98point/statement) were very low by the hypothesis-quality scale(Quinn and George, 1975) for the content-related hypotheses and the process-related hypothesis quality scale developed in this study. There was considerable correlation between the activity score and the 1st and 2nd hypothesis in the 2 staged inquiry investigations with the 2nd and 3rd topics($0.41{\ast}$, $0.59{\ast}{\ast}$ repectively).

This study examined the work time, work posture, and work intensity for the actual measurement step in forest road the design work that was being carried out. The measurement of the forest road was being carried by a team of three workers and a team of four workers. The examination of work time found that the measurement of 1km took about 8 hours for the four-worker team and 12 hours for the three-worker team. The examination of work intensity found that the energy metabolic rates of the three-worker team were lower than four-worker team. Because their energy consumption per minute decreased as their work time and rest time increased. Furthermore, when appropriate rest time was applied according to work time, the energy metabolic rate decreased and the work intensity became lower. The four-worker team was more advantageous from the time and cost aspects of the forest road measurement work. Furthermore, as the rest time was very low compared to the work time, more efficient forest road measurement work would be possible if the work intensity was lowered by considering the rest time when calculating the standard work time.
