This study investigated the effect of some affective variables on learning English as a foreign language. 219 students participated in this study by responding to a Likert-type scale instrument intended to measure their self-efficacy beliefs, motivation, task-value, and listening strategies. Through the application of the binary logistic regression analysis, it was revealed that listening strategies and self-efficacy beliefs were statistically significant variables that had some influence on the classification of the subjects into two groups; low-level students and high-level students. However, the other two variables, motivation and task-value in the equation, were not statistically significant. The findings of this study indicated that the teacher should help students increase their self-efficacy beliefs and listening strategies, which seem to have a direct impact on listening tasks and tests.
방과 후 스포츠 활동에 참여한 초등학생의 여가 경험과 생활태도에 관한 분석
심재우 ( Jae Woo Shim ) 한국여가웰니스학회 2015 한국레저사이언스학회지 Vol.6 No.1
본 연구의 목적은 방과 후 스포츠 활동에 참여한 초등학생의 여가 경험과 생활태도에 관해 질적 연구방법을 통해 알아보고 이를 심층적으로 분석하여 초등학생들을 위한 긍정적인 체육 여가문화를 구축하는 것이다. 본 연구의 결론은 다음과 같다. 첫째, 초등 방과 후 스포츠 활동은 참여자들이 느끼는 시간, 장소, 여가 동료 등 여가 활동에 관한 고충을 지정된 시간과 장소 등으로 여가 활동의 기회를 줄 수 있을 것으로 보인다. 둘째, 참여자들은 방과 후 스포츠 활동을 통해 다이어트 효과, 스트레스 해소 등의 건강 증진을 하였고 긍정적 대인관계, 사교성의 신장에 도움이 되었다. 셋째, 참여자들은 방과 후 스포츠 활동을 통하여 자신감과 자기효능감이 신장 하였으며 어느 정도 학습 효과가 있는 것으로 나타났다. 넷째, 학생들은 어디서든 활용할 수 있는 실력 향상과 함께 신체활동의 다양한 가치를 체험하는 것으로 나타났다. 본 연구를 통해 알아본 방과 후 스포츠 활동은 학생이 여가 생활로 주로 접하는 정적인 활동에 나타나는 문제점들을 보완하여 자연스럽게 동적인 활동으로 유도하는 것으로 나타났다. The purpose of this study was to investigate through qualitative research methods with respect to leisure life experiences and attitudes of elementary school students participating in after-school sports activities to analyze it in depth to build a positive culture for elementary physical education recreation. The results of this study are as follows. First, after elementary school sports activities participants felt the time, place, leisure time and place specified peers such complaints about the activities, all grades are expected to be able to give an opportunity for leisure activities such circumstances to mingle. Second, the participants resolved diet, stress through sports activities after school, key growth were health promotion, such as improved concentration that age, Line and positive interpersonal relationships with over the juniors, the extension of social assistance was. Third, the participants in the pilot program conducted during exercise and physical education through sports activities after school, self-confidence and self-efficacy, such as its role as a leader in the kidneys was seen that there is a learning curve to some extent. Fourth, students can take anywhere progress together with teamwork, goal accomplished accomplishment of activities, including promoting the health of the body were to experience a wide range of values of physical activity.

This study investigated 151 Korean high school students’ satisfaction with their native speaker teacher at a high school. Their levels of satisfaction were explored by a 5-point Likert scale that included 20 items related to English teaching in class. The subjects’ responses were submitted to the Winsteps program, which is one of the Rasch model software programs. The Rasch analysis indicated that more than half of the subjects were likely to be satisfied with every teaching strategy. In addition, the analysis showed that there existed four groups of items that gave some insights concerning the native speaker teacher’s teaching English in class. These four groups consisted of satisfaction with 1) the relationship with the native speaker, 2) the native speaker’s teaching method, 3) the native speaker’s intercultural understanding, and 4) increased confidence in English. Overall, there exists the need for more research on effective motivational strategies held by both native and non-native speaker teachers of English.

Objectives Our goal was to review literatures on tool-based manipulation for musculoskeletal diseases with emphasis on guasha and IASTM (Instrument Assisted Soft Tissue Manipulation) by searching foreign and domestic controlled trials. Methods We found literatures published up to August 2016 in electronic databases (OASIS, KoreaMed, KMbase, NDSL, RISS, KISS, MEDLINE/PubMed, EMBASE, Cochrane Central Register of Controlled Trials) without any limitations on language. Results 17 studies were included in the review. 13 out of 17 articles were published within this decade. VAS was the main evaluation tool for most of the articles (14 out of 17). 10 studies showed statistically significant difference between the experimental group and the control group. In terms of materials used for treatment, 6 out of 17 studies used stainless steel. Considering anatomical locations for treatment, trunk area was treated the most, accounting for 7 out of 17 studies. Conclusions Our results show that recently, research on tool-based manipulation treatments for musculoskeletal diseases are actively being performed. Diseases of the vertebral column were the main target for tool-based manipulation treatments, and stainless steel was the most popular and safe material used. Further research should be performed for more accurate data. (J Korean Med Rehabil 2016;26(4):57-65)
유화형 액막법에 의한 Zn 성분의 추출시 액막의 안정성
오치훈,황재석,심재우,이철태 ( Chi Hoon Oh,Jai Suk Hwang,Jae Woo Shim,Chul Tae Lee ) 한국공업화학회 1997 공업화학 Vol.8 No.4
유화형 액막을 이용하여 D₂EHPA-Kerosene-Span 80-H₂SO₄ 계에서 Zn성분의 추출시 액막의 안정성에 영향을 미치는 에멀젼의 파괴, swelling 현상 및 에멀젼의 morphology를 조사하였다. Zn 성분의 추출시 액막의 안정성에 대한 최적 조건은 계면활성제 Span 80의 농도 2∼3vol.%, 추출담체 D₂EHPA의 농도 5∼7vol.%, 막강화제 paraffin oil의 농도 10 vol.% 였으며, 외부수용액에 대한 에먼젼의 비 0.1, 유기상에 대한 내부수용액의 비는 1.0이 적절하였다. The stability of liquid membrane in the extraction process was investigated through the extraction of the Zn component by using W/O/W emulsion type liquid surfactant membrane which was D₂EHPA-Kerosene-Span 80-H₂SO₄ system. The highest stability for liquid membrane through the Zn extraction process was obtained under the following conditions. That conditions were that span 80 concentration, as surfactant, of 2∼3 vol. % ; D₂EHPA concentration, as extractant, of 5∼7 vol. % ; paraffin oil concentration, as membrane strengthening agent, of 10 vol. % ; emulsion volume ratio to the external aqueous phase volume of 0.1, and internal aqueous phase volume ratio to the organic phase volume of 1.0.
