본 연구는 우리나라 중학생의 음악흥미에 영향을 미치는 환경 심리요인(음악교사-학생관계, 부모의 음악학습관여)과 개인 심리요인(음악적 자기효능감)의 영향관계를 구조방정식모형을 통하여 검증하는 것이다. 이를 위하여 서울 A 중학교와 B 중학교의 1, 2학년 학생 400명을 대상으로 교사-학생관계, 부모의 학습관여, 자기효능감, 음악흥미의 정도를 측정하여 관계를 분석하였다. 연구결과, 학생이 느끼는 교사-학생관계가 긍정적일수록 학생의 음악흥미 향상에 긍정적인 영향을 주었고, 이 과정에서 자기효능감이 매개효과로 작용하여 음악흥미 향상에 긍정적인 영향을 주었다. 한편, 학생이 느끼는 부모의 학습관여는 음악흥미 향상에 직접적으로는 전혀 상관이 없었지만, 학생의 자기효능감을 매개로 하여 음악흥미에 긍정적인 영향을 주었다. 그리고 학생의 자기효능감 수준이 높을수록 음악흥미 향상에 직접적으로 긍정적인 영향을 주었다. 본 연구결과를 통해 부모보다 교사와의 상호작용이 학생의 음악흥미 향상에 더 큰 영향을 미친다는 사실을 확인할 수 있었다. 또한 환경 심리요인이 음악흥미에 영향을 미치는 과정에서 매개요인으로 자기효능감의 영향력이 상당히 크다는 사실을 확인할 수 있었다. 이를 바탕으로 본 연구는 음악흥미 향상을 위해 학생의 자기효능감을 높이는 환경을 조성하고 교사와 학생 간의 긍정적인 관계를 형성하기 위한 방안이 제시되어야 함을 시사한다. The purpose of this study is to examine the effect of students’ school students perceived teacher-student relationship and parental learning involvement on music interest through musical self-efficacy. To achieve this purpose, this study used structural equation modeling which is based on Interest theory and some empirical studies on music interest. The population of this study was the 400 students attending two middle schools. A survey questionnaire was conducted to measure variables of this study. It was consisted of teacher-student relationship, parental learning involvement, self efficacy and musical interest scale. The results suggested that Teacher-student relationship had direct effects and indirect effects on music interest, which are mediated by self efficacy. However, Parental learning involvement had no direct effects but indirect effects on music interest, which are mediated by self efficacy. Lastly, Self efficacy had direct effects on music interest. The results propose that teacher influences had more stronger than parental influence on music interest. In addition, Musical self-efficacy is an important psychological factor in predicting music interest.

The number of households with pets has increased in recent years. Consequently, interest in mites and their odors has increased. In this study, we investigated whether pyrethrum extract and water-soluble phytoncides are effective tick repellents, deodorizing agents, and antibacterial agents. In the tick-climbing test, the pyrethrum extract (23.33 points) and water-soluble phytoncide (22.00 points) showed a high repelling effect. To confirm the tick avoidance effect of the composite extract, a tick climbing test was conducted with a pest control extract, a composite extract (referred to as a sample) containing a water-soluble phytoncide, and a third-party product (control). The sample showed a high avoidance effect (13.00 points and Control 26.67 points. An indoor repellent efficacy test for ticks confirmed that the sample showed an excellent tick-repellent effect (88%) compared to the control (12%). As a result of a deodorization test, ammonia was shown to have a deodorizing effect of 98.3% and trimethylamine of 99.5%, whereas, in the antibacterial test, the E. coli, Staphylococcus aureus, and pneumonia groups showed an antibacterial effect of 99.9%. Combining the results of this study, it is judged that the complex extract including the above material has high utility value as a material that is effective in mite repellents, deodorization, and antibacterial activity.

연주전공생의 연주효능감이 내재적 연주동기에 미치는 영향 : 사회비교성향의 조절효과를 중심으로

권슬기(Kwon Seul Gi),백고은(Baek Go Eun) 학습자중심교과교육학회 2020 학습자중심교과교육연구 Vol.20 No.6

본 연구의 목적은 연주전공생들의 연주효능감이 내재적 동기에 미치는 영향에 대해 살펴보고, 사회비교성향이 두 변인 간 관계를 조절하는지 확인하는 데 있다. 이를 위해 2019년 4월부터 6월까지 두 달에 걸쳐 서울시와 경기도에 위치한 음악대학에 재학 중인 연주 전공생 300명을 대상으로 연주효능감, 사회비교성향, 내재적 동기를 측정하였다. 연구결과는 첫째, 연주효능감이 높은 경우 내재적 동기에 긍정적으로 유의한 영향을 미치는 것을 확인할 수 있었다. 둘째, 연주효능감이 높은 남학생의 경우 사회비교성향의 수준과 상관없이 내재적 동기를 많이 갖는 것으로 확인되었으나, 연주효능감이 낮은 남학생의 경우 사회비교성향이 높을수록 내재적 동기를 많이 갖는 것으로 확인되었다. 셋째, 연주효능감이 높은 여학생들은 사회비교성향의 수준이 높을수록 내재적 동기를 많이 갖는 것으로 확인되었고, 연주효능감이 낮은 여학생의 경우 사회비교성향 수준이 낮아질수록 내재적 동기를 많이 갖는 것으로 확인되었다. 본 연구를 통해 연주효능감과 내재적 동기 사이에서 사회비교성향의 역할이 성별에 따라 유의한 차이를 보이는 것으로 나타났다. This study examined the effect of music performance efficacy on music intrinsic motivation, and tested whether the relationship was moderated by different social comparison orientation of university students majoring in music-performance. After the regression analysis on the responses from 300 university students(majoring in Korean/Western vocal music and instrumental music) from April to June 2019, the results indicate that students who had high music performance efficacy had more high music intrinsic motivation. Also, male who had high music performance efficacy had high music intrinsic motivation regardless of their social comparison orientation level. On the other hand the more male who had low music performance efficacy compared with others, the higher they had music intrinsic motivation. Meanwhile, whaeras the more female who had high music performance efficacy compared with others, the higher they had music intrinsic motivation, the less female who had low music performance efficacy compared with others, the higher they had music intrinsic motivation. This illustrates how social comparison orientation on music performance the students had can affect the relation between students’ music performance efficacy and music intrinsic motivation according to their gender. Therefore, This result implies that educators should pay attention to students’gender, music performance efficacy and the level of social comparison orientation on performance to promote intrinsic motivation in music education.

본 연구는 버크셔종의 육질에 대한 특성을 분석하여 국내 돈육시장에서의 적합성을 확인하고, MS marker를 이용한 육질 우수 개체 선발의 효율성에 대해서 분석하였다. 버크셔 323두를 동일 사양조건에서 사육하고 도축하여 육질형질을 분석하고, 혈액으로부터 genomic DNA를 분리하여 50개의 MS marker에 대한 유전자형을 분석하였다. 버크셔종은 국내에서 가장 많이 이용되고 있는 듀록, 요크셔, 랜드레이스 종보다도 육질에 있어서 더욱 우수한 특성을 나타내었다. 특히 도축 24시간 후 pH 값은 평균 5.88±0.01로 대단히 높게 나타났고, 지방함량의 경우에도 2.878±0.06로 확인되었다. MS marker와의 연관성을 확인한 결과, 14개 MS marker가 육질형질과 연관성을 있는 것으로 나타났다(p<0.05). 특히 pH24hr와 지방함량에서는 가장 높은 값을 가지는 대립유전자집단이 가장 낮은 집단에 비해 최고 0.55, 2.04%가 높은 것을 확인할 수 있었다. 이러한 특성을 버크셔종의 육질 우수 개체 선발에 이용한다면 육색, 지방함량, pH24hr, 가열감량, 드립감량, 그리고 보수성에서 육질 형질값의 높은 개량효과를 기대할 수 있을 것으로 판단된다. In this study, the efficiency of microsatellite(MS) markers for pork quality was examined and further, their suitability to domestic pork industry also was verified, by measuring meat quality parameters of Berkshire breeds. A total of 323 pigs of Berkshire breeds were slaughtered and subjected to meat quality evaluation. In addition, the genomic DNAs from blood samples of slaughtered pigs were used for genotyping analysis of 50 MS markers. The results revealed that Berkshire breeds have excellent meat quality, compared with the popular domestic breeds such as Duroc, Yorkshire, and Landrace. Noticeably, the Berkshire breeds exhibited a significant post-mortem pH24hr(5.88±0.01) and fat content(2.878±0.06). Through the linkage analysis between MS markers, 14 MS markers showed significant association with meat quality traits(p<0.05). Maximum significant differences of 0.55 pH24hr value and 2.04% fat content were observed between the highest and lowest allele populations. If these 14 MS markers are applied to the pork quality diagnosis kit, the synergistic effect can be expected in meat quality parameters such as meat color, fat content, pH 24 hr, cooking loss, drip loss and water-holding capacity.

The BIPV, which is closely attached to windows and exterior walls, has problems with safety and deterioration of indoor thermal environment, which reduces the comfort of passengers. In contrast, a study was conducted to improve the thermal environment by combining BIPV with a two-layer louver condensation lighting system. In the office, the rooms were divided based on the center of the two windows, a two-stage louver was installed in the left window, and a BIPV was installed in the ceiling. On the right side, after installing the BIPV in the indoor window, the temperature, humidity and illumination were measured by the equipment installed in the same position every hour. As a result of the experiment, the longer the distance from the window, the lower the overall temperature, and the higher the temperature where the lighting louvers were installed on the second floor. The possibility of solar power generation using a second-floor luminescent louver was also confirmed because the illuminance difference was large near the window space and solar power generation modules were installed on the ceiling near the window.
