This work was carried out to investigate the changes in cropping systems and the factors influencing it during past 20 years from 1960 to 1980 at central Korea. 12 villages were selected as sample location based on the analysis of agricultural census, then the on-the-spot survey was carried out. The results were summarized as follows; 1. The barley in double paddy was planted over 50 percent of the paddy field at 1960's, on the other hand, it was decreased below 10 percent at 1980's. 2. The simple cropping system of barley-legume formed 70∼80 percent of total upland area at 1960's, but the various cropping patterns including such cash crops as vegetables and industrial crops were developed at 1980's. 3. The major factors influencing the change of cropping system were earnings, natural conditions of location and rural extension, whereas, the minor factors were release of new variety, cultural technique, markets, labor power and activities of farm leaders. 4. It was considered that the cropping system was influenced greatly by the natural conditions such as climate and soil conditions in case of the same technical, economical and social circumstances.

李正行,蔡濟天,具千書 단국대학교 1984 論文集 Vol.18 No.-

This work was conducted to investigate the changes in cultivated crops during past 20years in central region of Korea. The results were summarized as follows; In 1960's, 91∼92% of arable land was planted for cereal food crops, 4.5∼5.5% for vegetables and 2.4∼4.3% for potatoes, respectively. In 1980's, however, the acreage of cereal food crops was decreased dramatically, on the contrally, the acreage of vegetables and industrial crops were increased considerably. The acreage of barley, wheat, millet, soybean, azuki bean and sweet potato were reduced greatly, whereas rice was increased everywhere, and such cash crops as white potato, sesame, tobacco, vegetables and fruit trees were increased at most of the area during past 20years.

Objectives : To evaluate an association between depression and altered immunity, we examined peripheral T lymphocyte or natural killer (NK) cell measures plasma ACTH and cortisol using the flow cytometry in acute and unmedicated patients with major depressive disorder (MDD). Methods : Forty-two patients with MDD from the outpatient clinic and forty normal controls from the hospital staff were recruited. We applied Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) for depressed subjects. Peripheral T lymphocyte or NK cell measures (CD3, CD4, CD8, or CD56) and plasma hormones (ACTH and cortisol) were obtained from all subjects. Results : There were no statistical differences in CD3, CD4, CD8, or CD56 between the two subjects. The number of CD56 cells negatively correlated with HAM-D scores (r= -0.42, P<0.01), but did not correlate with HAM-A scores in patients with MDD. The number of CD56 cells showed strong negative correlation with CD4/CD8 (r= -0.47, P<0.01) in the control group, but not in the depressed group. Patients with MDD had higher cortisol level than controls within the normal range. Conclusion : The trait of immunological imbalance and HPA axis abnormality were shown in patients with MDD. Especially, the severity of depression, but not the anxiety, could be reflected as decreased number of CD56 (NK T) cells in acute and Unmedicated state.

Second. for injury cause, it showed that this is happening with the highest level of injury by the foul play and severe body battle with counterparts. Third, for injury frequency, it showed that this is happening with very low level, if it takes a long time in warming up before the game.

FW and DF players at the waist, elbow joint, pelvis, hand and wrist, and MF and FW players at the leg, Lastly, for injury type, it showed that DF and FW players largely undergo distortion. MF, FW, DF and GK players in the listed order at the muscle pain and MF and DF players leg pain, compared with other position.

이 연구의 목적은 스포츠클럽 활동에 참여하는 초등학생들의 신체인지와 공감력 및 체육수업기대와의 구조적인 관계를 실증적으로 규명하는데 있다. 연구목적을 위한 연구대상은 I시 재학 중이며, 학교 스포츠클럽 활동에 참여하는 4, 5, 6 초등학생 총 450명을 편의표본추출방법(convenience sampling method)을 활용하여 수집하였다. 자료분석은 SPSS 24.0과 AMOS 22.0 및 MIcrosoft Excel 프로그램을 활용하여, 탐색적․확인적 요인분석과 구조방정식 모형(structural equation model) 분석을 하였다. 연구결과는 첫째, 스포츠클럽 활동에 참여하는 초등학생의 체형에 대한 인지 수준은 공감력과 체육수업기대에 부분적으로 영향을 미쳤다. 둘째, 스포츠클럽 활동에 참여하는 초등학생의 운동에 대한 인지 수준은 공감력과 체육수업기대에 부분적으로 영향을 미쳤다. 셋째, 스포츠클럽 활동에 참여하는 초등학생의 공감력은 체육수업기대에 영향을 미쳤다. 넷째, 스포츠클럽 활동에 참여한 초등학생들의 공감력은 신체인지와 체육수업기대 간의 관계에서 간접(매개)효과를 나타냈다. This study verifies the structural relationship between physical perception and empathy of elementary students participating in sports club activities and the expectations for physical education classes. The subjects for the study were 450 students from an elementary school in I city who participated in sports clubs; they were selected using the convenience sampling method. Data processing was performed using the statistical software SPSS 24.0, AMOS 22.0, and Microsoft Excel (2016) programs, descriptive statistics analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and structural equation model analysis (SEM). The findings are as follows. First, the body perception of elementary students participating in sports club activities partially affected empathy and physical education class expectations. Second, the exercise perception of elementary students participating in sports club activities partially affected empathy and physical education class expectations. Third, the empathy of elementary students participating in sports club activities influenced the expectation of physical education classes. Fourth, the students revealed an indirect (mediated) effect on the relationship between physical perception and physical education class expectations.

이제행(Lee, Je Haeng) 한국체육교육학회 2021 한국체육교육학회지 Vol.25 No.4

이 연구의 목적은 스포츠클럽에 참여한 초등학생이 인지하는 건강과 신체인식 및 체육수업기대와의 구조적 관계를 실증적으로 규명하는데 있다. 연구 수행을 위한 연구대상은 인천 소재의 초등학교에 재학 중이며, 스포츠 클럽에 참여하는 학생을 편의표본추출법(convenience sampling method)을 이용하여 464명을 최종 표본으로 선정하였다. 자료처리는 SPSS 22.0, AMOS 22.0 및 Microsoft Excel 2016 프로그램을 이용하여, 기술분석(descriptive analysis)과 탐색적 요인분석(EFA), 확인적 요인분석(CFA)과 구조방정식 모형분석(SEM)을 실시하였다. 그 결과는 다음과 같다. 첫째, 초등학생들이 인지한 건강은 신체인식, 즉 체형인식과 운동유능감, 그리고 체육수업기대에 모두 정적(+)인 영향을 미쳤다. 둘째, 초등학생의 신체인식 중에서 운동유능감은 체육수업기대에 통계적으로 정적(+)인 영향을 미쳤다. 셋째, 초등학생이 인지한 건강과 체육수업기대와의 관계에서 신체인식의 하위변인 중에서 운동유능감이 부분적인 간접(매개)효과를 나타냈다. 즉 운동유능감은 건강인지와 체육수업기대 사이에서 간접(매개)효과를 가지는 변인이다. 따라서 스포츠클럽활동을 통해 초등학생의 운동유능감을 높여주는 것은 건강인식의 함양과 체육수업에 대한 참여 기대감을 높이는데 공헌할 수 있을 것이다. Purpose: The purpose of this study was to empirically verify the structural relationship between health and physical congnition perceived by elementary students who participated in sports clubs, and expectations for physical education classes. Methods: The subjects for the study were 464 students who are enrolled in an elementary school in Incheon and participated in sports clubs using the convenience sampling method. Data processing was performed using SPSS 22.0, AMOS 22.0 and Microsoft Excel 2016 programs, descriptive analysis, exploratory factor analysis(EFA), confirmatory factor analysis(CFA), and structural equation model analysis(SEM). Results: The findings were as follows: First, the health perceived by elementary students had a positive (+) effect on physical cognition and physical education class expectations. Second, among elementary students" physical cognition, exercise confidence had a statistically positive (+) effect on physical education class expectations. Third, in the relationship between the health perceived by elementary students and the expectation of physical education class, exercise confidence among physical cognition showed full indirect (mediated) effect. Conclusion: Enhancing exercise confidence in elementary students through sports club activities can contribute to cultivating correct health perception and raising expectations for participation in physical education classes.
