Purpose: The purpose of this study is as follows. First, the study tried to analyze the moderating effects of social distance and source expertise that is predicted to bring differences to brand attitude created through e-WOM. And second, tried to analyze the influence of brand attitude on purchase intention. Research design, data, and methodology: The collected data was analyzed using SPSS 22.0. Before testing the hypothesis, confirmatory factor analysis was conducted to test the construct validity of measurement items. Hypothesis about interaction effects between variables was verified using ANOVA and hypothesis about effects of brand attitude on purchase intentions was verified through regression analysis. Results: The result of this study is as follows. First, there was significance in the verification of interaction effects between direction of e-WOM and social distance. Second, there was also significance in the verification of interaction effects between direction of e-WOM and source expertise. Thus it can be said that brand attitude formed through e-WOM can defer according to social distance and source expertise. Third, it was confirmed that brand attitude had a positive (+) effect on purchase intentions. Conclusions: The implications of this study are as follows. Many studies regarding e-WOM focused on and studied direction of word-of-mouth messages and the characteristics of the messages themselves. However this study focuses on source related variables and verified that elements such as social distance and source expertise can bring differences in brand attitude. Also it was confirmed that variables related to source expertise is an important variable that can bring differences to brand attitude creation.

이형록(Lee Hyeong Rok),장일준(Chang Il Joon),이수범(Lee Soo Beom),김장욱(Kim Jang Wook) 대한토목학회 2010 대한토목학회논문집 D Vol.30 No.3D

서울시의 생활도로내 비신호교차로는 2008년 총 41,702건의 교통사고 가운데 3,753건(9%)로 교통사고 발생율은 높지 않은 실정이나, 교통 기초부분의 불합리하고 미비한 제도 및 시설 운영으로 인하여 사고의 잠재성이 더욱 높다고 볼 수 있다. 특히 생활도로내 비신호교차로의 경우는 신호교차로에 비해 안전대책이 미흡한 실정이며, 교통사고의 분석 및 영향요인 모형에 관한 국내 연구가 매우 부족한 상황이다. 또한 외국과는 달리 우리나라의 경우 비신호교차로 운영의 통행우선권 개념이 설정되어 있지 않기 때문에 생활도로내 비신호교차로의 안전성 향상을 위한 연구와 안전대책이 시급하다. 따라서 본 연구에서는 생활도로내 비신호교차로 이용자를 대상으로 개별면접 설문조사를 통해 수집된 안전도 이미지 데이터를 바탕으로 생활도로내 비신호교차로의 안전도 모형을 개발하고 법제도, 도로시설물, 인적요인 중 운전자 안전도에 가장 큰 영향을 미치는 요인을 분석하였다. 운전자가 느끼는 안전도에 가장 큰 영향을 미치는 요인인 통행방법 및 법제도를 개선한다면 생활도로내 비신호교차로의 안전도를 높여줄 수 있다. The unsignalized intersections in a community road in the city of Seoul have 3,753 traffic accidents(9%) of total 41,702 cases in 2008, not high in the occurrence rate of traffic accidents, but seem to have a quite high potential of accidents due to the unreasonable and insufficient operation of systems and facilities in the part of traffic foundations. In particular, the un-signalized intersections in a community road have an insufficient measure for safety as compared to the crossroads with signals, and there are few analysis of traffic accidents and domestic researches on the model of affecting factors. Our country also has no concept of passing priority in operating a crossroad without signals, differently from foreign countries, so the researches and safety measures for improving the safety of a crossroad without signals in a community road are urgent. Therefore, this research has developed a safety model for a crossroad without signals in a community road based on the safety image data collected through individual interviews and questionnaires for the users of unsignalized intersections in a community road, and confirmed that legal systems, road facilities, personal factors, etc. have the biggest effect on the safety of drivers. It was confirmed that the clarity of passing methods, establishment of legal systems, etc. have the biggest effect on safety in order to raise the safety of unsignalized intersections in a community road, which drivers desire.

A ranking of construction capability evaluation is the one of considering fact when a owner choose construction company. However, sometimes, companies faces financial problem even if they are in higher ranking of construction capability evaluation. This study is doing correlation analysis for their connection between management efficiency evaluation and a ranking of construction capability evaluation in top 100 companies of the ranking. Output factors have a minus in chosen input-output factors for evaluating management efficiency of construction companies. Moreover, this study uses DEA and BCC Models, because they have difference in a size. There are 23 efficient DMUs for efficiency evaluation and they are scattered over the field. However, size efficiency has directivity tendency. There are strong DRS disposition in high 50% companies, and IRS inclination in the others. Evaluating the effectiveness and value of construction skills ranked 1 to 10 units divided into sectors, our analysis of the results 1 to 10 belong to the one between companies, as well as the effective number of DMU average, highest, lowest at the differences between different sectors shows the superior efficiency compared to other sectors, but no direction could not be found. At the correlation analysis result, it is not very relevant the CRS and VRS efficiency between construction ability and efficiency rank. However, scale efficiency has gotten a strong relevance.

This study was conducted on 188 elite female athletes in 16 sports, comparing FMS™ results with other athletes, analyzing body imbalance and risk of injury. The results of the study were as follows. As a result of analyzing the difference in FMS score for each sport, the overall score was low in Hurdle Step and In-Line Lunge. ASLR recorded the highest score without distinction of sport, followed by Shoulder Mobility and Deep Squat. The overall score for each sport was the highest in athletics and the lowest in handball. In addition, the overall score was 14 points or less in all sports except athletics, curling, and wrestling and analyzed the difference in FMS scores for each sport, which showed that the ball sport recorded statistically lower score in Deep Squat compared to other sports. In the In-Line Lunge, individual sports recorded statistically higher scores than other sports and, shoulder Mobility scored statistically lower in combat sports than in other sports except for ball games. In the case of the overall score, winter sports scored the highest among the five sports, ball games recorded the statistically low score. This study result will provide more useful information for the prevention of sports injuries in elite athletes by presenting the relative results of dysfunction according to the asymmetry of athletes in each sport and event.

본 연구는 초등학생들의 줄넘기 운동 프로그램 참여에 따른 기초체력, 혈중지질, 운동습관에 미치는 변화를 비교·분석하고자 하였다. 총 322명의 초등학생을 대상으로 주 3회, 10주간 줄넘기 운동 프로그램을 실시하였으며, 최대심박 수의 45~65%로 시작하여 점진적으로 65~75%, 그리고 75~85%까지 운동강도를 점진적으로 증가시켰으며, 운동 프로 그램 이외의 생활은 평소와 동일하게 지내도록 하였다. 프로그램 참여에 따른 변화는 기초체력(심폐체력, 유연성, 근 력, 순발력), 혈액변인(총콜레스테롤, 중성지방, 저밀도 콜레스테롤, 고밀도 콜레스테롤), 그리고 생활습관(주당 운동 횟 수, TV나 컴퓨터 이용시간, 평균 운동시간 등)을 조사하였다. 프로그램 참여 전과 후에 따른 변화는 반복측정 이원변 량분석을 실시하였으며, 운동습관 변화에 대한 집단 간 전후의 변수의 차이는 교차분석을 실시하였다. 결과적으로 10 주간의 줄넘기 운동 프로그램 참여는 심폐체력의 기초체력 향상과 총 콜레스테롤, 중성지방, 그리고 저밀도지단백 콜 레스테롤의 유의한 개선 효과가 있었으며, 운동습관의 개선효과는 나타나지 않았다. 따라서 초등학생들의 줄넘기 운동 프로그램은 초등학생들의 건강한 생활을 위한 효과적인 운동프로그램으로 도움이 될 수 있을 것으로 판단된다. The purpose of this study was to determine the assessment of rope-skipping exercise training for the basal physical fitness, blood lipid profiles and exercise habits in elementary school children. The subjects were 322 children of the fifth to sixth grades of elementary school. Exercise group performed the combined rope-jumping training for 60 minutes/time, 3 days/week and 1st : 45~65%, 2nd : 65~75%, 3rd : 75~85% HRmax intensity for 10 weeks, whereas control group were asked to maintain normal lifestyle during the same period. Measuring materials were basal physical fitness(cardiorespiratory endurance, flexibility, muscular strength, and agility); blood lipid profiles(total cholesterol [TC], triglyceride [TG], low density lipoprotein cholesterol [LDL-C], and high density lipoprotein cholesterol [HDL-C]); and exercise habits (activity days per week, time using TV and computer, average exercise time per day, etc). The results showed positive changes in basal physical fitness(cardiorespiratory endurance, flexibility, muscular strength, and agility) and blood lipid profiles(TC, TG, and LDL-C) following 10 weeks of rope-skipping exercise training. However, all-life habits had not changed. These results suggest that rope-skipping exercise training may be effective for helping elementary school children.

체육수업 운동시간이 우울수준에 미치는 영향

김세형(Sae Hyung Kim) 한국데이터정보과학회 2019 한국데이터정보과학회지 Vol.30 No.1

이 연구의 목적은 고등학교 3학년 성별에 따라 체육수업 중 운동시간이 우울수준에 미치는 영향에서 자아존중감에 의한 자아탄력성의 조절된 매개효과를 검증하는 것이다. 연구대상은 한국청소년정책연구원에서 조사하고 공개한 ‘중학교 1학년 패널 6차년도’ 고등학교 3학년 2011명 (남학생 1014명, 여학생 997명) 이다. SPSS PROCESS macro 3.0 프로그램을 사용하였고 유의수준은 5%로 설정하였다. 남학생의 경우는 체육수업 시간에 활발한 운동으로 증진되는 자아탄력성 효과가 우울수준의 감소로 연결되기 위해서는 긍정적인 자아존중감이 필요한 것으로 나타났다. 여학생의 경우는 체육수업 운동시간이 증가함에 따라 자아탄력성은 향상되고 우울수준은 감소하지만, 자아탄력성이 자아존중감과 조합하여 주는 효과는 없는 것으로 나타났다. 또한 남학생과 여학생의 자아존중감이 우울수준에 미치는 직접적인 영향은 여학생이 남학생에 비해 자아존중감이 높을수록 우울감소 효과가 더 크게 나타났다. 이 연구로 남녀학생들에게 공통적인 정보는 유연한 자아탄력성을 가지고 체육수업 운동시간에 활발하게 참여할수록 우울수준이 낮아진다고 할 수 있다. The purpose of this study was to examine the moderated mediating effect of ego-resilience by self-esteem in the influence of exercise hours during physical education class on depression level. The subjects were 3rd year high school students 2011 (1014 male and 997 female students), which were investigated and released by the Korean national youth policy institute. The SPSS PROCESS macro 3.0 program in SPSS 24.0 program was used. The alpha level was set at 5%. In the case of boys, active exercise hours during physical education reduced depression level and interaction effect with positive self-esteem and high ego-resilience was significantly needed. In the case of female students, active exercise hours during physical education reduced depression level but interaction effect with self-esteem and ego-resilience was not significant. In addition, the direct effect of self-esteem on the level of depression was greater for girls than for boys. This study suggested that flexible ego-resilience and active participation in physical education classes made low depression level to both male and female students.
