The purpose of this study was to validate the selection attribute scale of an indoor surfing facility for marine sports. Specifically, data were collected from 183 individuals using the indoor surfing facility, and the Rasch measurement model was applied during the analysis. The conclusions and recommendations based on the research results are as follows: First, the selection attribute scale of the marine sports indoor surfing facility satisfied the assumption of unidimensionality in all factors. Second, it was found that a 3-point scale was suitable for the response categories in the selection attribute scale of the marine sports indoor surfing facility. Third, with regard to the appropriateness of the items in the selection attribute scale of the marine sports indoor surfing facility, two items were found to be inappropriate, while the rest of the items were found to be suitable. Fourth, it was determined that there were no discriminatory items based on gender in the selection attribute scale of the marine sports indoor surfing facility. In conclusion, the selection attributes of the marine sports indoor surfing facility should be measured accurately using a scale composed of 13 items in total, categorized into three response categories with a 3-point scale. It is expected that this scale will provide valid information about selection attributes and can be used as marketing information for activation without gender discrimination.

이 연구는 조정선수들의 경기력에 따른 운동관련 체력의 평가 기준을 설정하는데 목적이 있다. 이를 위해 2009년 현재 대한조정협회에 등록되어 있는 선수를 종목, 성, 경기력별로 35명을 연구대상으로 선정하였다. 수집된 자료에 대한 분석은 최근 의학과 임상학 분야에서 기준 설정과 관련하여 폭넓게 적용되고 있는 ROC 곡선분석을 적용하였다. 기준 설정을 위한 전제 조건의 검증을 위한 일원변량분석을 위해 windows용 SPSS 15.0 program을 이용하였으며, ROC 곡선분석을 위해 Medcalc 프로그램을 이용하였다. 이 연구의 분석에서 얻은 결과로부터 얻은 결론은 다음과 같다. 첫째, 성별 및 종목에 따른 운동관련 체력에는 차이가 있었다. 둘째, 경기력에 따른 운동관련 체력에는 차이가 있었다. 셋째, 남자 스위프 종목에서 근력 평가를 위한 절사점은 107.16kg이었으며, 유연성을 평가하기 위한 절사점은 18cm였다. 이 때절사점의 정확도를 확인하기 위한 AUC는 94.4%로 비교적 높게 나타났다. 넷째, 여자 스위프 종목에서 민첩성 평가를 위한 절사점은 17.26sec(AUC: 100.0%)였으며, 유연성 평가를 위한 절사점은 16.66cm(AUC: 84.4%)였다. 다섯째, 남자 스컬 종목에서 민첩성을 평가하기 위한 절사점은 16.86sec(AUC: 88.2%)였으며, 심폐지구력 평가를 위한 절사점은 8.13min(AUC: 65.3%)으로 나타났다. 여섯째, 여자 스컬 종목에서 근력을 평가하기 위한 절사점은 62.0kg(AUC: 100.0%)이었으며, 심폐지구력 평가를 위한 절사점은 9.16min(AUC: 62.5%)이었다. The purpose of this study was to set evaluation standard for motor-related physical fitness in rowing using ROC(Receiver Characteristic Curves) analysis. To accomplish this purpose, 35 elite rowers were participated in this study. Data were calculated by SPSS 15.0 for windows and Medcalc program. The conclusions of this study were as the followings: first, it was different from sex and event for motor-related physical fitness. second, it was different from sport performance for motor-related physical fitness. third, cut-off point for muscular strength was 107.16kg(AUC: 94.4%) and flexibility was 18cm(AUC: 94.4%) in men``s sweep. fourth, cut-off point for agility 17.26sec(AUC: 100.0%) and flexibility was 16.66cm(AUC: 84.4%) in women``s sweep. fifth, cut-off point for agility 16.86sec(AUC: 88.2%) and cardiorespiratory endurance was 8.13min(AUC: 65.3%) in men``s scull. sixth, cut-off point for muscular strength 62.0kg(AUC: 100.0%) and cardiorespiratory endurance was 9.16min(AUC: 62.5%) in women``s scull.

This study is to investigate the change and trend of the match record compared to the previous year according to the passage of time in the adjusted match record. For this, data from the National Indoor Rowing Championships were used, and a graph showing the change rate of the game record by gender, sport, and weight class and the trend of the game record was presented. Excel and SPSS programs were used, and the statistical significance level was set to .05. As a result, in the case of university general departments, there was a change and trend of shortening the game record regardless of gender and weight according to the passage of time. In the case of university general departments, positive effects were observed over time, but in the case of high school departments, it is judged that there is no trend of change, so appropriate measures need to be prepared.
해양레저스포츠의 SNS 서비스품질이 대학생의 행동의도에 미치는 영향 : 성별에 따른 조절효과 검증
강동균(Kang, Dong-Kyun),안상현(An, Sang-Hyun) 한국체육과학회 2023 한국체육과학회지 Vol.32 No.6
The analysis of the effect of the social-media-based marine leisure sports service quality factors on university students behavioral intentions was conducted, and the moderating effects based on gender were verified through univariate models of regression analysis and general linear models. The results of the analysis are as follows: Firstly, among the social-media-based marine leisure sports service quality factors, factors such as interactivity, informativeness, security, and aesthetics influenced satisfaction in university students behavioral intentions. Additionally, among the social-media-based marine leisure sports service quality factors, factors like interactivity, security, and usability influenced actual behavior in university students behavioral intentions. Secondly, in terms of the moderating effects based on gender, in university students behavioral intentions, satisfaction and behavioral factors acted as moderating variables only in the interactivity factor of the social-media-based service quality factors. Furthermore, females exhibited a higher tendency compared to males in terms of satisfaction and behavioral factors.
주기적 지형 측량을 통한 해빈과 해안사구의 지형변화: 충남 보령시 소황사구를 사례로
강동균 ( Dong Kyun Kang ),서종철 ( Jong Cheol Seo ) 한국지형학회 2012 한국지형학회지 Vol.19 No.2
충남 서천군 소황리 해안을 대상으로 광파측거기를 이용하여 해빈과 전사구를 정밀측량한 후 중기간의 해빈과 해안사구 지형 변화를 분석하고 그 결과를 현지의 풍계와 장기간 지형변화와 연관시켜 검토하였다. 4회에 걸친 측정값을 1m 해상도의 DEM으로 변환하여 분석한 결과, 연구 지역의 지형 발달 방향은 바람의 방향보다는 인공 구조물의 영향이 큰 것으로 나타났다. 연구지역 중앙에 위치한 도류제와 남단에 신축된 방조제에 의해, 도류제 북쪽에서는 퇴적이, 도류제 남쪽에서는 침식이, 그리고 연안류에 의해 방조제 근처에 지속적인 퇴적이 발생하였다. 해빈과 해안사구는 측정시기에 따라 침식과 퇴적이 반복되어 퇴적물 교환이 주기적으로 일어남을 알 수 있었다. 향후 주기적이고 지속적인 정밀 측량이 이루어지면 연구 지역 일대에서 일어나는 지형 변화의 원인을 정확히 밝힐 수 있을 것으로 생각된다. The aim of this study is to analyze the mid-term changes of beach and dune morphology at Sohwang beach, Korea using by Total Station. Measurements executed 4 times during two year. Based on ArcInfo as point cloud obtained through precise measurement data by Total Station, alteration of beach and dune was analyzed at DEM, of which cell size is about 1m. Since these artificial constructions have influenced current systems of this region, the large-scale sand movements above mentioned have occurred around the jetty and the sea-wall. There occurred sedimentation in the north of the Jetty and erosion in the south of the Jetty, which is installed at the central part of object area. The direction of recent topographic development does not coincide with that of wind, and, rather, topographic changes occurred mainly at beaches and dunes due to the transformation of coastal water flow caused by artificial structure nearby. If precise measurement is conducted periodically, and long term monitoring is carried out by installing equipment measuring movement pattern of sediment around artificial structure, cause of topographic change around the object area could be discovered.
