  • The purpose of this study was to identify the relations among questions level, questions process, and hesitation factor of questions. Data were collected from 174 students at a university in D city using structured questionnaire from September 9 to April 10 2015. It was analyzed with frequency analysis, descriptive statistics, t-test, ANOVA, and correlation analysis. As a result, the learners' questions are made from cognitive confusion, these questions led the students to ask a question actually. Also, this study confirmed that the learners' internal hesitation factors had negative correlation when the students asked a question in real situation. In order to improve the asking question we'll need to be generating a lot of questions to the student's inside and outside. We also need to develop appropriate teaching methods so that this can be perceived connection of cognitive confusion-having questions-asking questions.

  • 생산성 저해 요인의 제거는 바로 생산성 향상으로 연결된다. 뽕밭의 생산성을 저해하는 요인은 여러가지지만 그 중에서 토양의 이화학적 불량과 농약 공해가 비중이 가장 크다고 볼 수 있다. 우리나라 뽕밭은 입지가 경사지에 많으므로 토심이 얕은데 비해, 뽕나무는 영년성 심근성 작물이므로 식재후 근권의 물리성에 따라 생산성이 좌우되는 비중이 매우 크다. 그러나 식재후 토양 물리성 개량은 화학성 개량보다도 어려우므로 그 결과 생산성이 낮은 상태를 벗어날 수 없다. 따라서 정기적인 심경이나 심토 파쇄를 통한 물리성 개량이 요망된다. 계속적인 금비위주의 비배관리에 의해 강산성 반응을 보이는 토양이 대부분이므로 석회에 의한 산성개량이 필요하다. 질소질의 과다시비는 수량을 감소시킬 뿐만 아니라, 엽질을 악화시키고 질산태 질소가 지하로 흘러 들어가 지하수의 오염을 일으켜 청색증과 암을 일으키는 원인이 될 수 있다. 심각한 정도로 축적된 인산과 칼리도 수량을 떨어뜨리고 환경을 해치는 원인이 되므로, 축적 양분의 재활용에 대한 연구가 계속되어져야 한다. 특히 사용의 편리성 때문에 고농도의 복합비료 위주의 비배관리가 반복되고 있는 실정이므로 토양검정을 받아서 단비를 이용하여 적정한 시비를 해야 할 것이다. 이러한 방법은 생산성의 향상, 영농비의 절감, 공해의 유발을 억제하는 여러가지 효과가 있다. 농약과 산업공해로부터 양잠의 보호를 위해서는 안전지대에 잠업의 단지화, 인근 농과와의 대화를 통해서 양잠에 안전한 농약을 사용토록 하는 한편, 연구분야에서는 심도 있는 연구를 통해 양잠농가를 보호할 수 있는 대책의 수립이 요망되고 있다. 종합해서 말하자면 연구기관의 심도있는 연구가 더욱 활발히 이루워져야 할 것이며, 농민은 개발된 새기술에 보다 깊은 관심을 갖고 활용하는 한편, 필요로 하는 기술을 연구기관에 개발을 요청할 정도의 적극적인 자세가 요구된다. 또한 연구기관의 농민의 중간 교량역할을 하는 지도부문에서도 보다 적극적인 활동이 요청된다.

  • 고성능 마이크로 프로세서들은 성능 향상을 위해 ILP를 지원한다. 병렬성을 극대화시키기 위해서는 많은 성능 저해 요인들을 제거해야 한다. 최근에는 컴파일러의 역할을 증대시켜 이러한 요인들을 줄이기 위한 노력들이 활발히 진행되고 있다. 본 논문에서는 성능 저해 요인인 조건 분기 처리를 위하여 조건 실행과 레지스터 할당을 결합함으로써 메모리로의 대피를 최소화하고 병렬성을 향상시킬 수 있는 개선된 레지스터 할당 알고리즘을 제안한다. 제안한 방법을 적용하여 실험한 결과 간섭 그래프의 에지수가 4.47% 감소되었고 그 결과 요구되는 대피 변수의 수도 21.35% 감소되었다. 그리고 기존의 방법에 비해 19.38%의 성능 향상 결과를 얻었다. 결국 본 레지스터 할당 기법은 조건 실행을 통해 조건 분기 명령을 제거하여 기본 블록 내의 명령어 수를 증가시켜 병렬처리의 기회를 증진시키고 조건 분석을 통해 간섭 그래프의 불필요한 에너지를 제거시켜 보다 효율적인 레지스터 할당을 실현함으로써 제안한 방법의 타당성을 검증하였다.

  • Since enforcement of the anti-prostitution law, in spite of systematic setting helping escape prostitution of the women who engage in prostitution that they have had the will lasting prostitution. Therefore, this study aimed to devise intervention plan helping their escape prostitution and return to social by examining individual and structural factor obstructing their escape prostitution The data were collected through the in-depth interview and text. And these were analysed according to coding, constitution of concept, matching, construction of explanation on the phenomenon. The nine women who engaging in prostitution were participated in this study. As a result of the data analysis, 46 concepts and 10 categories were generated. By classification of individual and structural factor, the outcomes of an interpretation were as follows: The cause obstructing Prostitutes' escape prostitution were (1) distrust on the policy of the government, (2) life-script was made by reaction-formation, (3) predestined resignation caused by anxiety, (4) body as capital goods, and (5) the commensal model with pimp. Based on this result, we proposed practical and political alternative plans for prostitutes.

  • This study is to investigate what the factors motivating the wheelchair basketball club members to participate in the wheelchair basketball club are and what the factors hindering the members from participating in the wheelchair basketball club are, based on which it has been conducted to explore the effective direction of the management of the wheelchair basketball club for the physically disabled persons in the future. For this study, a survey targeting 180 members currently participating in the wheelchair basketball clubs in Seoul, Gyeonggi, Chungcheong, Gyeongnam, Jeju areas has been conducted and the data gained from 144 respondents of them have been analyzed and its key results of this study are as follows. Firstly, the results of analyzing the physically disabled persons' motives of participation in the wheelchair basketball club show that the respondents have most frequently participated in the wheelchair basketball club by their motives of the pastime-oriented type, which was followed by the health-oriented one, then by the home-oriented one. The results of examining the difference in the motivations for participation based on the degree of participation in the wheelchair basketball club and on the social demographic characteristics of the club members show that there was a significant difference depending on the group by residence, the subjective health condition in the light of the pastime-oriented motives and there was significant difference depending on the age, the occupation, the group by residence, the frequency of participation. Secondly, according to the results of investigating and analyzing the factors hindering the members of the club from participating in the wheelchair basketball club for the physically disabled persons, the structural factors are found to have been the biggest hindrance factor of participation and there was a significant difference depending on the age, the highest level of education, the occupation, the frequency of participation in the club in verifying the difference in the hindrance factors of participation in the club in accordance with the social demographic characteristics of the club members and the frequency of participation in terms of internal factors. Based on the abovementioned research results, some future effective management strategies of the wheelchair basketball club for the physically disabled persons have been discussed.
