The fundamental aim of this study is to identify how the organization and utilization of a supplementary workout program in accordance with the physical education curriculum for fifth year elementary students influences their basic physical strength and s

The purpose of this study was to compare the difference of joint position sense between measurements. Fourteen healthy male subjects were recruited for this study. The elbow joint position senses were measured using angle reproduction test. The elbow joint position sense was assessed with three experimental conditions: ipsilateral reproduction test in open-chain condition, contralateral reproduction test in open-chain condition, ipsilateral reproduction test with weight in open-chain condition and ipsilateral reproduction test in closed-chain condition. The angular difference between stimulus position and the reproduced position (angular error) was calculated in all testing conditions to examine the accuracy of the joint position sense. One way ANOVA was used to compare the error angles in all experimental conditions. The error angles between measurements were significantly different in elbow joint. The error angles was smallest in ipsilateral reproduction test with weight in open-chain condition and was greatest in the contralateral reproduction test in open-chain condition. Findings of this study indicate that testing methods, types of task, existence of resistance should be considered in clinical assessment for the joint position sense.

Objective : This paper presents an empirical study on the bias toward the disabled by the students studying occupational therapy, who will make an expert group to take care of them in the future. It was investigated how much sense of distance the students had according to the physical characteristics of the disabled. Method : Total 128 students majoring in occupational therapy were asked to fill out a self-administered questionnaire. The physical characteristics of the disabled and the sense of distance toward the disabled were measured as follows: The visible physical characteristics of the disabled were restricted to the disorders of external physical functions based on the Article 29 ‘Classification of the Disabled’ of the Disabled Welfare Act. The functional characteristics of the disabled were measured by using the FIM (Functional Independence Measure) method. Meanwhile, Westie (1952)’s inventory of the sense of distance was adopted for the inventory for the sense of distance toward the disabled in the study. Results : The subjects showed the biggest sense of distance toward the disabled in the order of the disabled with encephalopathy, physical handicap, language disorder, visual disturbances and acoustic disturbances. As for the functional characteristics, the sense of distance was the greatest in the order of the completely dependent disabled, partially dependent disabled, and completely independent disabled. The average sense of the distance was compared in terms of the subjects’ school and year, and the results revealed there were statistically significant differences in all the areas except for the sense of distance toward the completely dependent disabled. Conclusions : The sample needs to be expanded in number, and random sampling is required to secure diverse social and cultural backgrounds. In addition, the causality verification should be done in order to understand the nature of sense of distance in a study on it according to the physical characteristics of the disabled. Finally, an evaluation tool needs to be developed that can be used to measure the sense of distance toward the disabled.

It was recently reported that exercise-induced fatigue is related to joint position sense although some controversy remains. The purposes of this study were to examine the effect on the accuracy of reproducing the knee angles after a fatiguing isokinetic quadriceps exercise at four different levels (10%, 30%, 50%, and 70% of maximal force) and to find the optimal exercise level without causing knee joint proprioception impairment. Forty healthy women, ages 19 to 27, were randomly assigned to four experimental groups. Before and after the exercise, accuracy of positioning with respect to auditory feedback for specific angles was estimated by calculating the mean errors between specific angles and reproduction angles. Fatigue was measured by EMG signals displayed by a frequency spectrum analysis during the quadriceps exercise. Results showed that there was no significant difference in accuracy of the knee joint positioning sense following the exercises in group 1, group 2, and group 3 (10%, 30%, and 50% of maximal force, respectively); the exception being group 4 (70%). Fatigue level was significantly increased in group 4 but there were no significant increases of fatigue level in group 1, group 2, or group 3. The results concluded that the optimal exercise level to acquire the therapeutic exercise effectiveness without position sense impairment was at 50% of maximal force. Further studies using large sample size and patient groups with poor knee joint proprioception would be needed to confirm this conclusion and to clarify the possibility of clinical applications.

이 論文은 魚類의 視覺능력을 硏究한 것이며, 視力軸의 방향과 視角과 의 問題에 관계된 몇가지 事實들을 관찰하고 있다. 필자는 어류의 시식조직에 대한 해부학상의 구조를 설명하고 여러 시력軸들이 생활양식과 어떻게 연관지워져 있는가를 연구했다. 변사와 nylon系를 볼수있는 능력에 대한 재미 있는 실험을 했으며, 미끼(먹이)에 대한 어류의 반응에 대하여도 연구하였다. 예를들면, 어류가 미끼에 대한 흥미를 느끼게 되려면 미끼의 움직임이 있어야 하며, 어류는 자기의 먹이를 일정한 거리에서 볼 수는 있으나, 미끼를 꽉 물어뜯게 만드는 원인은 미끼의 요동에 의해 생기는 물이 움직임이라는 것이다.

This study verified the influence of socioeconomic status on the subjective well-being of the elderly and the mediating effect of social justice. A statistical analysis of 4257 data in the China CGSS 2017 database was carried out. The analysis results show that socioeconomic status and social justice have a positive impact on the subjective well-being of the elderly, and the social justice plays an incomplete intermediary role. Based on the results of the analysis, this study puts forward several suggestions in terms of policy and practice. First, government may gradually increase the level of pension benefits of the elderly, and provide minimum living security. Second, the community should provide amenities for the elderly to settle their life inconveniences. This research will help improve the subjective well-being of the elderly

학교소속감이 중도탈락을 막을 수 있는 중요한 변수임에도 불구하고 특히 고등학교 학생에 대한 학교소속감 연구는 그 수가 많지 않다. 아직 충분한 연구가 이루어지지 않은 분야에서 기계학습 기법을 활용하는 탐색적 연구가 학문적 기여를 할 수 있다. 본 연구의 주요 목적은 일반고 및 특성화고 학생들의 학교소속감을 예측하는 중요한 변수를 파악하는 것이다. 이를 위하여 부산교육종단 연구 2016 4차년도 데이터의 일반고와 특성화고 학생, 교사, 교장, 학교 변수를 모두 활용하였다. 구체적으로 75개 일반고 1,775명의 824개 변수 자료와 36개 특성화고 739명의 854개 변수 자료를 기계학습 기법으로 분석한 결과, 일반고와 특성화고에서 각각 20개와 21개의 학생, 교사, 학교 관련 변수가 선택되었다. 학교소속감을 개인의 심리적 차원에 초점을 맞추어 분석한 선행연구와 달리, 본 연구는 교사, 교장, 학교 변수까지 모두 모형에 투입함으로써 학교 현장에서의 변화를 꾀하였다. 기계학습 기법 중 벌점회귀모형으로 분류되는 glmmLasso를 활용하여 변수 선택 시 자료의 위계적 구조를 반영한 점 또한 연구 의의라 하겠다. 특히 특성화고 자료는 사례 수보다 변수 수가 더 많은 고차원 자료였으므로 기계학습 기법을 활용하는 것이 필수적이었다. 연구 결과를 토대로 고등학생의 학교소속감을 향상시키기 위하여 필요한 정책적 제언을 제시하고, 후속 연구주제 또한 논하였다.
