The purpose of this study was to examine the performance of formaldehyde removal from building materials using catechin contained in ginkgo leaf. A small chamber method was used to set up one control group and three experimental groups. As a result, it showed a reduction of formaldehyde from at least 73.5% to 77% when it was increased by 0.4g compared to the control (0g). In addition, it was confirmed by linear regression analysis that the amount of ginkgo leaf and the amount of formaldehyde emission were negatively correlated. Therefore, it was confirmed that the amount of formaldehyde emission was affected by ginkgo leaf.

Purpose: This study analyzed building heating, cooling, and lighting energy performance and power generation performance under various climate zones in accordance with Solar Signage Semi-transparent window application. Method: American climate areas, them being tropical, desert, maritime, and microthermal, have been selected and 40%~80% window wall ratio (WWR) has been established in relation to five Solar Signage Semi-transparent windows. Designbuilder, building energy analyzation software, was used to model office building and simulate. Result: Total energy consumption presented Phoenix was highest, followed by Miami, Ann Arbor, with San Francisco being the lowest. The smaller the WWR the higher the heating energy consumption at San Francisco and Ann Arbor appeared with G1 window confirmed to be the highest. Cooling energy consumption in all four climate zones increased as WWR increased due to increase in amount of solar gain. Lighting energy consumption in all four climate zones decreased as WWR increased, with G5 showing smaller consumption than G1 due to VLT’s influence. Climate zone with the amount of energy savings on account of power generation being largest turned out to be San Francisco. Especially, possibility of zero energy building achievement in case of G1, G2 window being applied when WWR was 80% was confirmed. With the result of this particular research, to expand applicability as building exterior materials, products improved upon traits such as colour, insulation, and strength should be under continuous performance evaluation study across various foreign and domestic climate zones.

The purpose of this study was to examine differences and relationships of the daycare teachers’ perception on music pedagogical content knowledge and music teaching efficacy so as to provide materials for teacher training program revision. The subjects were 212 nursery teachers in B city. Collected data were statistically processed using PASW 19.0, and the results of this study are as follows. First, teachers' perceptions on music pedagogical content knowledge of curriculum knowledge were higher than those of curriculum contents, teaching and learning method, and learners while the teachers' perceptions about music teaching efficacy turned out to be higher in results expectation than in the beliefs in the process of music teaching. Second, the differences in the background variables showed significant difference only in the teacher’s academic background both in the music pedagogical content knowledge and music teaching efficacy. Finally relationship was found between teacher’s perception of music pedagogical content knowledge and of music teaching efficacy. These results strongly suggest that individual teacher educational attainment may be helpful for one’s teaching ability development and there are needs of teacher training program revision with concern on music pedagogical content knowledge and music teaching efficacy. 본 연구의 목적은 음악교수내용지식과 음악교수효능감에 대한 보육교사의 인식의 정도와 차이 및 관계를 알아보는 것이다. 이를 위해 B도시에 근무하는 보육교사 212명을 대상으로 설문조사하였고 수집된 자료를 PASW 19.0로 통계 처리하였다. 연구 결과 첫째, 음악교수내용지식과 음악교수효능감에 대한 보육교사의 인식의 정도는 보통의 수준이었고 하위요소별로는 교육내용, 교수학습·방법, 교육과정(누리과정) 및 학습자(유아)에 대한 이해로 구성되는 음악교수내용지식 증 음악교수내용이나 교수·학습법에 비해 누리과정에 대한 이해가 더 높게 나타났다. 음악교수효능감에 대해서는 음악교수 결과기대를 음악교수 신념 보다 더 높게 인식하는 것으로 나타났다. 둘째, 각각의 하위요소 간의 차이를 보육교사의 배경변인별로 살펴본 결과 음악교수내용지식과 음악교수효능감 모두가 학력에서만 인식의 유의미한 차이가 있는 것으로 나타났다. 셋째, 음악교수내용지식과 음악교수효능감은 모든 하위요소 간에 통계적으로 유의미한 정적 상관관계가 있는 것으로 나타났다. 이상의 결과는 보육교사에게 음악교육내용지식에 대한 이해와 음악교수효능감의 증진 모두가 영유아음악교육의 활성화에 필요한 기반으로서 이를 기초로 유아음악 교사교육이 실시되어야 할 필요성을 시사한다.

The purpose of this study is to develop an intelligent model that can estimate the clothing insulation (CLO) of occupants using real-time images. Also, performance and applicability of the model to the actual environment were analyzed through the experiment. A total of 16 individual garments and 9 clothing ensembles were set for the model development. The model was developed using the YOLOv5 network and trained on the collected clothing data. The classification performance of the developed model was denoted as 86.7% on average. The applicability of the model was evaluated using the real-time images of the subjects in the test-bed. As a result, the insulation value of the clothing ensembles can be accurately estimated with the MAE of 0.01 clo. This study confirmed the outstanding performance of the CLO estimation model and its high applicability to the actual indoor environment. Therefore, employing the CLO estimation model can contribute to improvement of occupant’s thermal comfort, and it is expected to be applied to various systems capable of PMV-based control.

연구목적 : 본 연구는 작업치료사에게 감염관리에 대한 연구의 경향을 분석하여 향후 국내에서의 적용을 위한 근거자료를 제공하고자 한다. 연구방법 : 본 연구는 2000년부터 2019년까지 출판된 문헌을 대상으로 RISS, KISS, Google scholar를 통해서 검색하였다. 총 41개의 논문이 검색되었으며, 선정기준과 배제기준을 통해서 최종 4개의 문헌을 분석하였다. 연구결과 : 분석결과 질적 수준은 4편(100%) 모두 근거수준 Ⅳ로 나타났다. 연구대상자인 작업치료사의 근무 분야는 연하재활 치료실 2편(50%)으로 가장 많았다. 감염관리는 인식도가 실천도보다 높게 나타났다. 결론 : 본 연구를 통해서 국내의 작업치료사 감염관리에 대한 연구가 부족한 실정을 확인할 수 있었다. 향후 국내 실정에 맞는 감염관리를 위한 연구, 임상 환경에 맞는 감염관리 프로그램의 개발 및 효과성에 대한 연구가 필요할 것이다. Objective : The purpose of this study is to provide basic data for future application of occupational therapists to the domestic market by analyzing the trend of research on infection control. Methods : This study was conducted through RISS, KISS, and Google scholars for literature published from 2000 to 2019. The final 4 articles were analyzed through selection criteria and exclusion criteria among 41 articles. Results : As a result of the analysis, the qualitative level of all 4 articles(100%) was evidence level IV. In the field of work of occupational therapists, the subjects of the study were 2 articles(50%) dysphagia rehabilitation therapy rooms. The awareness of infection control was higher than the practice. Conclusion : This study confirmed the lack of research on infection control of occupational therapists in Korea. In the future, it is necessary to study for infection control suitable for domestic situation, development of infection control program suitable for clinical environment, and research on effectiveness.

This study was conducted to examine a effect of scalp massage on decrease of stress. A total of 15 student who find a position with high-strength stress were included. The scalp massage were provided with 16 times (2 times/8 weeks). The degree of stress were measured by survey baseline and after 8 weeks. After a scalp of 8 weeks, a significant decrease in total score of stress (p<0.000). And, scalp massage is effective for depression, fatigue, failure and concern. Also, the subjects experienced a great sense of relaxation and comfortableness. In conclusion, scalp massage is effective intervention strategy to decrease stress. These results suggest that more effective intervention program based on scalp massage is need to provide an individually with stress.

본 연구는 거리에 따른 유류비를 고려하여 시간가치를 산정하고, SP 조사를 통해 경로선택 시 통행시간, 통행요금과 함께 거리에 대한 유류비를 반영함이 타당한지 분석하는 것을 목적으로 하였다. 수준 차이를 고려한 SP 조사설계기법을 이용하여 SP 자료를 구축하여 분석하였으며, 통행시간, 통행요금 및 유류비에 대한 가치를 추정하기 위한 모형식을 구축하였다. 모형 추정 결과, 경로선택 시 통행요금과 함께 유류비 역시 운전자의 경로선택에 영향을 미치는 것으로 나타났다. 경로선택에 있어 통행요금이 유류비에 비해 더 큰 것으로 나타났는데, 이는 통행요금이 현금지불경비(out-of-pocket expenses)인 반면 유류비 지출은 주기적이라는 특성 때문에 유류비가 통행요금에 비해 덜 민감하게 나타난 것으로 보인다. In this study, the value of travel time was estimated with reflecting the fuel cost according to travel distance. The main objective of this study is whether the addition of the fuel cost as a factor for route choice behavior is appropriate or not, through the stated preference survey. The route choice model was developed using SP survey technique with the consideration of level difference and the value of travel time, toll and fuel costs. Consequently, the fuel cost is identified as a main factor like travel time and toll cost in choosing routes from drivers' viewpoints. Nevertheless, since toll costs are recognized as out-of-pocket expenses whereas fuel costs as periodical expenses, it seems drivers are more sensitive to toll than fuel costs.
