In this study, thermal environment changes for a marathon course of IAAF World Championship, Daegu 2011 were modeled to provide improvements of thermal environment, so that runners could have the maximum condition and citizens pleasant streets. The three biggest size of intersections were selected for the study. Envi-met, 3G microclimate model, were used for a thermal environment analysis and three different cases - present status, planting roadside tree scenario, and roof-garden scenario - were compared. The followings are the results of the study. 1. The highest thermal distribution were shown at 1 p.m., but there was no significant difference between a thermal distribution at 1 p.m. and that at 5 p.m. since a heat flux from buildings affects thermal distributions rather than insolation does. 2. Tree planting or adding environmental friendly factors might lead a temperature drop effect, but the effect was not significant for areas covered with impermeability packing materials such as concrete or asphalt (especally, for Site case 2) 3. The combination of tree planting and adding environmental friendly factors also brought a temperature drop effect (Site 1 and 2) and this case showed even better result if green spaces (especially, parks) were closed.

대구는 2011년에 세계육상선수권대회(IAAF World Championships)를 개최하였다. 조직 위원회는 이 대회를 통해서 대구에 대한 세계적인 인지도를 강화하고, 세계적인 스케일에서 관광과 투자를 촉진함으로써 최근 대구의 경기침체를 극복하고자 하였다. 한국에 거주하는 외국인의 관점에서 쓰여진 본 논문은 문화지리 분석 방법을 혼합하여 세계육상선수권대회로 인해 파급된 관광과 투자의 영향을 평가하였다. 본 논문은 대규모 이벤트를 활용한 장소의 생산을 고찰하기 위해 세 단계의 '영토화(territorialisation)' 접근법를 적용하였으며, 특히 세계육상선수권대회가 개최되기 전과 개최되는 동안의 재현 활동(representational efforts)을 살펴보았다. 이 과정에서 웹사이트, 안내책자 등과 같은 대회 관련 홍보물이 주로 사용되었으며, 관광객을 대상으로 한 인터뷰를 통해 연구 결과를 보충하였다. 이와 관련한 문헌 자료, 대구의 역사, 그리고 Daegu 2011의 추진 배경을 검토한 결과, 본 논문은 세 가지 항목으로 도출되었다. 첫째, 비판 담론 분석(critical discourse analysis)을 통해 대회와 관련된 홍보 비디오를 분석한 결과 대구시는 세계 관광 시장에서 차지하는 대구의 지위에 대하여 불확신한 것으로 나타났다. 둘째, 관광지로서 대구의 위상에 대한 대구시 자체의 불확신은 홍보 비디오 이외의 다른 홍보물 분석에서도 여전히 나타났다. 이런 홍보물들은 대구시의 이미지와 미래를 향한 염원에 부담을 초래하였다. 셋째, 이런 논의를 확장시킨 결과 홍보물에서 보여지는 대구의 관광 경관은 실제 보여지는 경관과 부분적으로 차이가 나타나고 있었다. 이것으로 볼 때, 세계선수권대회는 대구시에 긍정적인 효과를 창출함과 동시에 앞으로 세계적인 도시로서의 위상을 확립하기 위해서 해결해야 할 과제를 남기고 있다.

The purpose of this study was to explore the effect of 8 weeks after school classes of track sports on students' start motion through kinematic variables. 30 students in D National university of education participated for this study. These students divided into two groups, 17 students for experimental group and 13 students for control group. The two groups participated in general athletic class as common class, and the experimental group participated in after school class additionally. The general class taught track and jump skill for 3 hours a week, and the after school class taught only athletic running skill for 30 minutes a week. Pre and post test assessed to assess students' kinematic changes. Findings indicated that velocity and step rate were increased, and contact time, step length, displacement of center of mass were decreased in the experimental group. In the control group, early velocity, knee/hip angle velocity were increased, and contact time, step length, displacement of center of mass were decreased. In conclusion, the students who only participated in general class, could not maintain athletic skills obtained from the class. However, students who participated in both general and after school class accomplish athletic start skill. This is because Continuous learning effect helped students keep the skill and did not lose the skill. Thus, in order for students to learn specific sport skills, joining after school class with general class together is recommended.
