T-STEAM 프로그램이 기술교과의 흥미도와 학업성취도에 미치는 효과
윤정교,김방희,김진수 한국교원대학교 교육연구원 2013 敎員敎育 Vol.29 No.3
이 연구의 목적은 중학교 1학년 기술 수업에 활용할 수 있는 T-STEAM 프로그램을 개발하고 실제 수업에 적용하여 학생들의 흥미도와 학업성취도에 미치는 효과를 알아보는데 있다. STEAM 교육관련 선행연구와 기술교과 교육과정 분석의 문헌 고찰을 바탕으로 준비, 개발, 실행, 평가의 PDIE 절차에 따라 연구를 수행하였다. 과학, 기술, 공학, 예술, 수학교과 교수 및 현장교사 29명의 자문을 통해 T-STEAM 프로그램을 개발하고 타당성을 확보하였다. 개발된 4개의 T-STEAM 프로그램(8차시)을 경기도 부천 소재의 중학교 1학년 2개 학급을 대상으로 실제 수업에 적용하여 흥미도와 학업성취도에 미치는 효과를 분석하였다. 유의 수준 0.05에서 독립표본 t-검증을 실시한 결과, 개발된 중학교 1학년 기술 교과용 T-STEAM 프로그램 활용 수업은 학습자의 흥미도(교과흥미, 교과 내용, 교과 가치 및 노력, 교과 유능감, 교과 담당 교사)를 향상시키는데 효과적으로 나타났다. 두 집단 간의 사후 학업성취도 검사 결과를 분석한 결과 유의한 차이가 없는 것으로 나타났다. The purpose of this study is to find the effects of T-STEAM program in the middle schoolfirst grade technology subject on degree of students’ interest in technology subjects and theiracademic achievements. To achieve this study, analyzed STEAM theories and curriculum ofthe middle school first grade technology subject, developed 4 T-STEAM programs by usingPDIE model and performed experimental researches on the programs. The research subjectsare 72 students of two freshmen classes. The experiments were done 8 times in total. Andanalyzed statistical data using t-test for independent samples to see whether the difference inthe averages of two groups was statistically meaningful, and set the significance level of 0.05. T-STEAM program-utilizing lessons show significant differences in the learninginterest(subject-interest, curriculum content, subject-value and effort, subject-competence, andsubject teacher). These differences show that the T-STEAM program is effective to enhance thelearning interest. And T-STEAM program classes were not effective in improving the academicachievement.

한국성인의 근감소증과 류마티스 관절염 및 골관절염의 관련성: 국민건강영양조사 2008-2011
윤정교,김정훈,최윤형 대한운동학회 2017 아시아 운동학 학술지 Vol.19 No.3
[PURPOSE] This study aimed to investigate the associations of sarcopenia with rheumatoid arthritis and osteoarthritis in the general population of Korean adults. [METHODS] We analyzed the data for 11,466 adults aged ≥40 years from the Korea National Health and Nutrition Examination Survey 2008-2011. Dual-energy X-ray absorptiometry was used to measure the skeletal muscle mass. Sarcopenia was defined when the appendicular skeletal muscle index was less than the sex-specific average minus the two standard deviations in the young reference group(age, 20-39 years). Survey logistic regression analysis was used to assess the association of sarcopenia with rheumatoid arthritis and osteoarthritis. [RESULTS] Sarcopenia status was dose-dependently associated with a higher risk of rheumatoid arthritis, after adjustment for potential confounders(p-trend=.002, odds ratio [OR], 2.14; 95% confidence interval [CI], 1.13, 4.05 in sarcopenia group vs. high muscle mass group). However, a higher risk of osteoarthritis was observed in pre-sarcopenia group compared with the high muscle mass group(OR, 1.45; 95% CI, 1.03, 2.05), but not in sarcopenia group. [CONCLUSIONS] We found that sarcopenia status was associated with rheumatoid arthritis, and pre-sarcopenia status was associated with osteoarthritis. Our findings suggest that maintaining a skeletal muscle could be beneficial in preventing musculoskeletal disorders, including rheumatoid arthritis and osteoarthritis.

Background: Humidifier disinfectant is a biocidal product used in the water tanks of humidifiers to prevent the growth of microorganisms. Although there are a huge number of cases of reported humidifier disinfectant-related health effects across the entire Korean population, their numbers are distributed differently depending on the region. Objectives: This study aimed to investigate the regional distribution of enrollment cases who reported humidifier disinfectant-related health effects. Methods: This study used data on 6,240 subjects who experienced humidifier disinfectant-related health effects and who enrolled their cases which is conducted by the Korea Ministry of Environment. We examined the regional distribution of the enrolled cases based on sixteen administrative divisions and assessed the: 1) crude number; 2) proportional rate; and 3) age-standardized proportional rate of enrollment by region. Results: When we examined the crude number of enrollments by region, the highest number were in Gyeonggi-do Province (n=1,896), followed in order by Seoul (n=1,405), Incheon (n=436) Busan, Daegu, Gyeongsangnam-do Province, Daejeon, Chungcheongnam-do Province, Gyeongsangbuk-do Province, Jeollabuk-do Province, Gwangju, Chungcheongbuk-do Province, Gangwon-do Province, Jeollanam- do Province, Ulsan, and Jeju-do. When we examined proportional rate of the regional enrollment (cases per 100,000 population), Daejeon (n=16.2) was the region with the highest rate, followed in order by Gyeonggi-do Province (n=16.1), Incheon-do Province (n=15.9), Seoul, Daegu, Gwangju, Jeollabuk-do Province, Chungcheongnam-do Province, Busan, Chungcheongbuk-do Province, Gangwon-do Province, Gyeongsanbuk-do Province, Gyeongsangnam-do Province, Ulsan, Jeju-do, and Jeollanam-do Province, which is inconsistent with the order in terms of crude numbers. However, when we examined the age-standardized proportional rate of regional enrollment (cases per 100,000 population), their ranked distribution is consistent with the crude rate. Conclusions: This study observed that the regional distribution of the enrolled cases who reported humidifier disinfectant-related health effects is inconsistent with the regional distribution of the proportional rate of enrollment cases, which may be caused in part by the volume of the inherent population of each region.

Objectives: The aim of this study was to introduce the overall progress of exposure assessment to humidifier disinfectant (HD); to present participants’ demographic characteristics, exposure characteristics to humidifier disinfectant, and exposure classification; and furthermore to compare those characteristics between survivors and non-survivors. Methods: An assessment of environmental exposure to HD was conducted using modified HD-specific questionnaires that had been previously validated. We analyzed the data from 4,482 participants who had been potentially exposed to HD and had registered with the KEITI (Korea Environmental Industry & Technology Institute) from September 2016 to May 2018 (the fourth survey). Environmental exposure assessments were performed as follows: 1) contact with participants, 2) environmental exposure assessment though face-to-face interviews, 3) assessment review and coding, and 4) exposure rating. Results: Overall, survivors made up 77.1% (3,457 subjects) and non-survivors made up 22.9% (1,025 subjects). When compared with the survivors, non-survivors had a higher proportion of subjects aged >60 years and subjects who answered as suffering lung damage and having purchased HD because it is “Beneficial to health” (p<0.05). For the exposure characteristics compared to survivors, non-survivors had a higher proportion of cases of distance from humidifier to face being less that one meter and the spray direction being toward the face (p<0.05). Overall, respondents who used the “Oxy Ssak Ssak New Gaseupgi Dangbun”, “Aekyung Gaseupgi Mate”, “Homeplus Gaseupgi Chungjungje”, and “E-Mart Gaseupgi Salgyunje” products made up 66.1, 12.3, 4.0, and 3.6%, respectively, and 72.5% of respondents used products with PHMG as the active chemical.?When compared with survivors, non-survivors had a higher proportion of use of “Oxy Ssak Ssak New Gaseupgi Dangbun” but a lower proportion of use of products with CMIT/MIT, PGH, or PHMG as the active chemical. Conclusions: This study provided demographic characteristics and exposure assessment for applicants who have been injured by HD. In spite of the limitations of performing past exposure assessment through a questionnaire survey, such as recall bias, useful results may be obtained by comparing survivors with non-survivors. Further studies such as the exposure rating method and so on are necessary to assess past exposure to HD.

서비스디자인을 적용한 문화예술공간에 관한 연구 -금호아트홀 연세를 중심으로-
윤세정 ( Sejeong Yun ),이정교 ( Junggyo Lee ) 한국공간디자인학회 2016 한국공간디자인학회논문집 Vol.11 No.5
(Background and Purpose)Modern society is transforming into an economic service society, triggered by the increase in interest in service, as well as diversification in the consumers`` experiences and needs. Demands are also increasing for cultural art experiences. Thus, appropriate service design is essential in cultural art spaces to satisfy consumers`` demand. This research analyzes how service design elements are applied in cultural art spaces to identify its primary role. (Method) This research will study the principles and trends in service design, and service design elements`` application in spaces will be extracted through an element analysis. The scope is narrowed based on such criteria to the Kumho Art Hall Yonsei among various cultural art spaces, and its spacing is also specified. The researchers analyzed the service design elements in the space by coding the Touchpoint method in the Kumho Art Hall Yonsei, and examined each case in the property. This method analyzed service design characteristics, which were then applied to a touch point in each detailed space. It then studied how these characteristics are reflected in the cultural art space depending on the service design``s components. These theories were considered and reflected in the case analysis`` results; the results were ultimately derived regarding the roles and values of the service design as applied to cultural art spaces. (Results)First, the space provided a fluent cultural art experience, and service to the users was harmonious between the space and the service design property. Second, the space with the highest distribution result among other cultural art spaces was the one that reflected the users`` experiences and needs: convenience, interaction, and information. Third, the service design property with least distribution result needed self-complimentary strategies to satisfy service users`` needs in their active space experience. (Conclusions)The researchers discovered through this study that service design is an essential element to improve corporate image as this satisfies the users`` needs for cultural art experiences. Additionally, it could be predicted that it is necessary to plan cultural art spaces to evenly distribute the characteristics by reflecting the service design components that form the space. Further, it was confirmed that the service design property is a necessary prerequisite to adapting optimized space design programs and high-quality space design policies in an economic service society. Finally, research must be sustained regarding service designs for the user``s experiences in various spaces.
