The purpose of this study was to investigate difference of activity of scapular stabilizer muscles among push-up, knee push-up and wall push-up exercise. Eight male college students were recruited as participants without any history of shoulder or pathology. The results showed that serratus anterior, anterior deltoid, infraspinatus were higher muscle activities than other scapular stabilizer muscles during push-up exercise and muscle activity of standard push-up exercise was higher muscle activity than that of Knee and Wall push-up exercise. Also, We know that knee push-down exercise was more effective than wall push-down exercise for scapular stabilization.

본 논문에서는 프로그래밍 교과에서 학습참여도가 성취도에 끼치는 영향을 규명하였다. 학습참여도는 예습참여도, 수업참여도, 복습참여도로서 학습활동별로 측정되었다. 중다회귀분석 결과, 세 개의 독립변수는 성취도를 설명하는 모형은 유의한 것으로 나타났다. 예습참여도는 성취도에 유의한 영향을 미치지 않았으며, 유의한 영향을 미치는 두 요인 중 상대적 기여도는 복습참여도, 수업참여도 순인 것으로 분석되었다. 이러한 연구결과에 기초하여 프로그래밍 교과의 성취도 향상을 위한 교수학습 전략을 제시하였다.

본 논문은 옵션의 표준 이격도를 정의하고, 이격도에 따른 매매 전략을 제시하며, 이의 수익을 분석하였다. 옵션 가격은 내재가치와 시간가치인 프리미엄으로 분리되는데, 프리미엄은 만기일에 가까워질수록 줄어들어 0에 수렴한다. 따라서 행사가와 선물가격과의 차이와 만기일까지의 잔존시간의 두가지 변수에 대한 옵션 평균 가격을 계산해낼수 있다. 그 평균 가격과의 가격 차이를 표준 이격도라 한다. 기본적인 스트랭글 매도 전략에 진입 시점과 청산 시점에 표준 이격도를 사용하였다. 표준 이격도가 높으면 매도 진입하고 표준 이격도가 낮으면 매수 청산하였다. 2010년 9월물을 사용하여 실험한 결과 약 8%의 수익률을 기대할 수 있었다. 향후에 옵션 표준가격을 추출하기 위한 샘플 기간에 대한 연구가 필요하다.

The Conception of the Dao(道) have a large number of implication. The Dao is Taoism's representative concept, also the Confucianists considered the Dao important. But relatively the Confucianists emphasize the way of Human(人道), Taoists stress the way of Heaven(天道) The Justice is the western philosophical conception. The Justice is necessary for the peace and prosperity in interindividual, inter-social, and international. If closely consider, We can explain the real nature of Justice from the Dao, and know practicing the Dao is namely practicing the Justice. In this paper, I studied the conception of Dao and it's meaning in the philosophy of Lao-tzu (B.C. 604?~531?) and Confucius(B.C. 552~479), and researched the method of practicing the Justice. Through this study, I ascertain that Confucian's the way of Human is the Benevolence(仁), practicing the Benevolence is namely practicing the Justice. And Lao-tzu's he way of Heaven is the real nature of Justice, Nature itself remained intact(無爲自然) is namely practicing the Justice.

This article is a preliminary essay for comparative study on Lao Zi Note of Park Sae Dang who lived Lee Dynasty in 17C and Hayashi La Zan who lived Doku Kawa Bakuhu in 17C. This article have two points at issue. First one is the their challenge that resisted the dogma of their own age. And the other one is their challenge of thaught had the academic background of the Lao Zi Note. They had a their own Lao Zi Note, Park Sae Dang朴世堂 had a New Note of Lao Zi 新註道德經 and Hayashi La Zan 林羅山 had a Selection Note of Lao Zi 老子抄解. However there are some different points between Park Sae Dang and Hayashi La Zan. The Hayashi La Zan's comprehension of Lao Zi followed in Lao Zi Note of Lin Xi Yi 林希逸 who had a point of Confucian comprehension of Lao Zi, so the study of Taoism of Hayashi La Zan excepted Zhuang zi. Hayashi La Zan concentrated on only Confucian comprehension of Lao Zi because Lin Xi Yi's Note of Zhuang Zi had a point of Zen Buddhism. However Park Sae Dang's the study of Taoism has Lao Zi and Zhuang Zi. He understood Lao Zi and Zhuang Zi in a base on Confucian comprehension. He indicated Confucian moral principle 修身治人 for a equal point of between Confucianism and Taoism. And he understood Cheng Xin成心 in Qiwulun in Zhuang Zi is similar to Xing性 of Xing Shan性善 in Meng Zi. Park Sae Dang analyzed not simply Lao Zi but also Zhuang Zi in a base on Confucian comprehension.

This essay is an analysis on Daoist deconstructivism and Confucian constructivism about music and language. (1) Daoist criticizes that the Confucian constructive music and language fail to describe original sounds and original facts of doing nothing (wuwei, 無爲). According to Daoist, music and language can be an instrument to describe true facts in the world. So Daoists try to attain a state of 'seeing things as things themselves (yiwuguanwu, 以物觀物)' by 'forgetting oneself (wangwo, 忘我).' (2) However Confucian music and language is a part of one's life. Confucians try to get truth, goodness, and beauty by exercising one's music and language. Confucian music is associated with political and moral development in society. The Confucian genres of poetry (shi, 詩), appealing letter (shu, 疏), declaring writing (biao, 表), record (ji, 記), and written words (ci, 詞) are processes of developing one's life. Further, Confucian rhetoric of 'Xing (興)' in writing poem shows that one's language can be developed in contexts of one's life. (3) Although music and language is associated with human subjective narratives as if Confucians say, diverse narratives of different subjectivity cannot appear in one's lives if all kinds of narrative is absorbed in Confucian absolute ideological slogan to devide things into good and bad. Accordingly, the Confucian view of music and language can develop diverse narratives when it does not show an inclination toward moral dichotomy preunderstood by Confucian ideology.

The purpose of this study is to improve the validity of the evaluation by adding the factor of academic achievement to the subject of evaluation, and to improve the reliability of the evaluation by verifying the legitimacy of control of in-class attitude and developing the correction index of satisfaction of teaching. The results of the study are as follows. Firstly, it was confirmed that the students' in-class attitude had a significant effect on satisfaction of teaching. The more positive the in-class attitude, the higher the satisfaction of teaching, and vice versa. Secondly, it was confirmed that the students' in-class attitude had a significant effect on academic achievement. The more positive the in-class attitude, the higher the academic achievement, and vice versa. Thirdly, it was confirmed that satisfaction of teaching did not have a significant effect on academic achievement. High satisfaction of teaching does not mean that the quality of the teaching is high, and vice versa. Fourthly, the correction index of satisfaction of teaching was developed to correct the results of satisfaction of teaching that may be distorted due to the students' negative in-class attitude. In conclusion, academic achievement should be added as the subject of evaluation in addition to the satisfaction of teaching to improve the validity of evaluation and the correction index of satisfaction of teaching should be applied to improve the reliability of evaluation.

The CTD(Cumulative Trauma Disorder) as a new kind of occupational disease occurs mainly to workers on handling line under the highly-specialized industrial environments. This study took into account their exposure to Cumulative Trauma Disorders(CTD) by the utilization of EMG system, with respect to worker's muscle fatigue test according to fulfillment of iterative and simple task. The findings of this study were as follows : From the result of AEMG test analysis, worker's fatigue extent according to elapsed time of task was inclined to be increased continually. On the other hand, after its task ending, their fatigue extent was inclined to be decreased than before-circumstance of refractory brick lifting. The transference of MF(Median Frequency) and MPF(Mean Power Frequency) had highly significant difference between muscle fatigue and the elapsed time of work. Especially, their fatigue extent to erectorspinae and multifidus to lift firebrick was increased in the mean time. The transference of ZCR(Zero Crossing Rate) had considerable significant difference between muscle fatigue and the elapsed time of work. In short, as the work went of the muscle fatigue extent increased gradually. Thus, it can be concluded that the fatigue of erectorspinae and multifidus extent according to fulfillment of iterative and simple task is gradually being increased.

This study was carried out to select proper loading speed for deformation strength ($S_D$) of asphalt mixtures. Kim test using loading head of diameter(40mm) with radius(10mm) was conducted to measure $S_D$ in different loading speed (10mm/min, 30mm/min, 50mm/min, 70mm/min) and wheel tracking test was also conducted. The regression analyses between the So values and WT results were carried out by loading speeds. Higher $S_D$ was observed as increasing loading speed. This means that loading speed is a high influencing factor on $S_D$. The loading speed of 30mm/min was found as an optimum for better correlation with WT results than any other speeds from the regression analysis between $S_D$ and wheel tracking test results. $S_D$ value measured at other loading speed than 30mm/min has to apply the conversion coefficients.
