Purpose: The purpose of this study was to investigate effect of open kinetic chain exercise on the motor function of the lower limb in middle school soccer players. Method: The subjects consisted of 14 soccer players who attend middle school in Gwangju. All subjects received open kinetic chain exercise for 3 weeks. The muscle strength of the ankle was measured by a commander muscle tester. Postural control ability was measured using a hopping test. All measurements for each subject were conducted pre-intervention and 3 weeks post-intervention. Result: There were significant differences post-intervention in the muscle strength and-the postural control ability of the open kinetic chain exercise group(p<.05). Conclusion: Open kinetic chain exercise had a significant positive effect on the motor function of the lower limb in soccer players. Therefore, open kinetic chain exercise may prevent and resolve injury with careful management while soccer players are training or playing games. It could be helpful to extend the lives of athletes and improve their records.

This research was intended to reveal the reality of education in counseling graduate schools belonging to special graduate schools through phenomenological research and to shed light on the need for special graduate schools as institutions for training experts from the perspective of students. The subjects of the study were eight adult men and women in their 20s and 40s. Those who had completed more than four counseling-related subjects belonging to the special graduate school were selected as subjects. In-depth interviews were conducted on the master's course of eight subjects, and the data was analyzed according to Colaizzi's phenomenological method. Results showed that there were 157 units of meaning, which were integrated into 47 subjects. These were grouped into 15 topical groups and categorized into five groups. A brief presentation of the results and conclusions of the study is as follows. The study found that there are life changes in the process of getting into special graduate schools, the educational environment, difficulties as graduate students, and overcoming difficulties. Finally, the significance and limitations of this study were presented. 이 연구는 현상학 연구를 통하여 특수대학원에 속한 상담전공 대학원생들의 경험을 밝히며, 전문가 양성기관으로서의 특수대학원의 현실을 학생의 관점에서 심층적으로 조명하고자 하였다. 연구의 대상자는 20대~40대 성인 남녀 8명으로, 특수대학원에 속한 상담대학원 상담 관련 과목 4개 이상 이수한 사람을 대상자로 선정하였다. 8명의 연구 참여자에게 석사과정에 대한 심층 면담을 시행하고 Colaizzi의 현상학적 방법에 따라 자료 분석하였다. 수행결과, 의미 단위는 157개로 나타났으며, 47개의 주제로 통합되었다. 이는 15개의 주제군으로 묶여 5개로 범주화되었다. 연구의 결과 및 결론을 간략하게 제시하면 특수대학원 진학 동기, 교육환경, 대학원생으로의 어려움, 어려움에 대한 극복, 어려움 극복과정에서의 삶의 변화가 도출되었다. 마지막으로 본 연구의 의의와 제한점을 제시하였다.

본 연구에서는「공공수역 방사성물질 측정망 운영 계획」에 따른 모니터링 수행 내용을 소개하였고, 하천 및 호소 60 개 지점을 대상으로 인공방사성물질(<sup>134</sup>Cs, <sup>137</sup>Cs, <sup>131</sup>I)의 농도를 조사하여 우리나라 지표수 내 방사성물질의 실태를 파악하고자 하였다. 채취된 시료는 마리넬리 비커를 이용한 감마분광 분석기법으로 분석하였다. <sup>134</sup>Cs와 <sup>137</sup>Cs은 모든 지점에서 MDA 미만으로 조사되었고, <sup>131</sup>I는 한 지점(0.533±0.058 Bq/L)을 제외한 모든 지점의 농도가 MDA 미만으로 나타났다. <sup>131</sup>I는 의료용으로 사용하는 물질로 환자의 배설물로 인해 하수처리장 인근 하천수에서 빈번하게 검출되는 물질로 알려져 있다. 따라서 <sup>131</sup>I가 검출된 원인을 파악하기 위해 하수처리장 방류지점을 포함한 <sup>131</sup>I가 검출된 상류수계 6개 지점을 추가 조사하였다. 조사결과, 하수처리장 처리수 방류지점에서부터 하류방향으로 <sup>131</sup>I가 지속적으로 검출되었으며, 농도는 0.257±0.034~0.799±0.051 Bq/L 범위로 조사되었다. 추가조사를 통해 하수처리장 방류수가 하천수의 <sup>131</sup>I 검출에 영향을 미치는 것으로 나타났다. A survey of the artificial radionuclides in rivers and lakes was conducted to investigate their levels in surface water. Water samples were collected at 60 points and analyzed by gamma-ray spectrometry with a measurement time of 10,000 seconds for <sup>134</sup>Cs, <sup>137</sup>Cs, and <sup>131</sup>I. The obained values were lower than MDA for all points, except one point for <sup>131</sup>I that was 0.533±0.058 Bq/L. <sup>131</sup>I is known as a radioactive material that occurs frequently in sewage treatment plants. Because it is often used for medical treatments and subject to spreading into the environment due to the excretion from the patients. For the point where <sup>131</sup>I was detected, we conducted additional investigation on the upstream river point and the effluent points of nearby sewage treatment plant to find the source of <sup>131</sup>I. <sup>131</sup>I was not detected at the upstream points of one of the upstream sewage treatment plants but found at the downstream points with the level being 0.257±0.034 to 0.799±0.051 Bq/L, proving the sewage treatment plant was the <sup>131</sup>Isource.
