The purpose of this study is to establish a standard for the body composition of women's national team athletes by weight class and use them as basic data to plan a training program and determine the timing of return by injury recovery. From 015 to 2020, 310 body composition data of 22 people belonging to the national team were used. Through ROC analysis, body composition, skeletal muscle, obesity, muscle by region, and intracellular and extracellular hydration factors were set as standards. The conclusion is as follows. First, there were statistically significant differences in all sub-factors in the body composition according to the performance level of each weight class of the female national rowing athletes. Second, the standard values of body composition according to the performance level of the heavy-weight female national team athletes include intracellular moisture(C.P.=27.55), extracellular moisture(C.P.=16.25), body moisture(C.P.=43.65), protein(C.P.=11.75), and Muscle mass(C.P.=56.25), lean mass(C.P.=59.55), skeletal muscle mass(C.P.=33.45), right arm(C.P.=3.315), left arm(C.P.=3.32), trunk(C.P.=26.25). This was shown as a discriminating factor. Third, in terms of the standard values of body composition according to the performance level of the women's national team athletes of light-weight, intracellular moisture (C.P.=23.75), extracellular moisture(C.P.=13.95), body moisture(C.P.=37.45), protein(C.P.=10.25), and Muscle mass(C.P.=48.25), minerals (C.P.=3.625), lean mass(C.P.=51.15), skeletal muscle mass(C.P.=28.85), right arm(C.P.=2.66), left arm(C.P.=2.66), trunk(C.P.=22.45), Right leg(C.P.=8.12), left leg(C.P.=8.04), the AUC values of the factors were .70 or higher, which were discriminating factors.

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.

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.

This research was carried out to provide strategic references to help build performance improvement approaches for rowing athletes and teachers, by analyzing the patterns of rowing movement that are the most critical elements for athletic conpetitiveness. For this puipose, power and performance data for strokes were measured from the rowing movements by 34 rowing athletes using Biorower. The measured figures including the total numbers of strokes, lengths, frequencies, power, and angle were analyzed using SPSS 18.0,at each rowing section and by genders. The analysis results are as follows: First, the total numbers of the strokes were significantly different by athletic capacities and genders. The numbers by men rowers and the national team members were higher than the women’s and the non-national rowers’ Second, the lengths of strokes were longer in men and the non-national teams than in women and the national teams. The stroke numbers per 1 minute were significantly different by athletic performances. On the level of the non-national there were significant differences by genders, while on the level of the national there were no differences by genders. Fourth, power of a stroke showed significant differences by capacities and genders, and men and the national team were higher than women and the non-national team. Fifth, the angles of strokes were significantly different by genders and capacities. The stoke angles of men and the national members were larger than the women‘s and the non-nationals. At present, from the analysis results of rowing movements using Biorower by genders and athletic performances, there were significant differences between the national team athletes and the non-national athletes.
