          의료소비자의 정보탐색행태와 지각된 위험이 고객만족도에 미치는 상대적 영향

          채유미,이선희 한국보건행정학회 2010 보건행정학회지 Vol.20 No.3

          Objective : The purpose of this study is 1) to understand the information-searching behavior of health care consumers ; 2) to examine the relationship between the information-searching behavior of health-care consumers and regulatory variables such as socioeconomic factors,characteristics of medical utilization, and perceived risks ; and 3) to determine the factors that affect consumer satisfaction, especially with respect to information-searching behavior. Method : The data for this study were collected from 838 respondents in five university hospital located in three areas—Seoul, Gyeonggi province, and Chungchong province. As the first step of the study, we conducted a preliminary survey from September 23–26, 2008. At the second step, we conducted a survey on the effect of information-searching behavior on those individuals who had visited. Furthermore, personal interviews were conducted through a face-to-face survey between September 30 and October 17, 2008. Results : The major research findings that were obtained from the study were as follows : First, the age, educational level, and residential district were associated with information source utilization. Second, the level of information searching effort and quality of service had a significant effect on consumer satisfaction. Conclusion : These results show that it is essential for marketers to have in-depth knowledge about the young and educated people who actively search for information and about those who are in the prime of their life and rely on word-of-mouth communication from personal and experi in-al informers. Therefore, marketers should develop different marketing strategies to meet the needs of such consumers.

          의학용어학습에서 자기주도학습준비도 촉진 수업방식의 효과 분석

          채유미 한국산학기술학회 2020 한국산학기술학회논문지 Vol.21 No.6

          This study was designed to examine whether the self-directed learning method could improve self-directed learning readiness and the effects of academic achievement level. Self-directed learning readiness was investigated among 63 first-year Medical Terminology undergraduates in the C area. A repeat measurement variance analysis of the general linear model was conducted to evaluate the effects of improving self-directed learning readiness according to the general characteristics and level of academic achievement, while a regression analysis was performed to identify the factors affecting self-directed learning readiness. Self-directed learning readiness increased from 177.3 to 180.8 for those under 18 years of age, and 192.9 to 196.5 for those over 19 years of age (p<0.05). After the team activity, the overall self-directed learning readiness was improved, and both high- and low-achieving groups showed statistically significant improvements (p<0.05). The environment surrounding learners was confirmed to have a positive effect on improving self-directed learning when given the right degree of self-directed learning and appropriate feedback. The study results are expected to form basic foundation material for professors and class designers who want to draw self-directed learning skills from memorizing subjects. 본 연구는 자기주도학습 촉진 수업방법이 자기주도학습준비도를 향상시킬 수 있을 것인지, 학업성취도 수준에 따른 효과를 살펴보고자 하였다. C 지역 4년제 보건행정학과 1학년 ‘의학용어' 수강생 63명을 대상으로 팀활동 중심의 자기주도학습 촉진 수업방법 적용 후 자기주도학습준비도를 조사하여 SPSS 24.0 통계 프로그램을 이용하여 비교분석하였다. 자료조사는 2016년 9월 6일 1차, 12월 6일 2차로 이틀에 걸쳐 진행되었다. 일반적인 특성과 학업성취도 수준에 따른 자기주도학습준비도 향상 효과를 평가하기 위해 일반선형모형의 반복측정 분산분석을, 자기주도학습준비도에 영향을 미치는 요인을 확인하기 위해 회귀분석을 실시하였다. 자기주도학습준비도를 연령별로 살펴보면 18세 이하군은 수업 전 177.3점에서 180.8점, 19세 이상군은 192.9점에서 196.5점으로 향상되었다(p<0.05). 수업 후 전반적인 자기주도학습준비도 향상을 보였으며 학업 성취도가 높은 그룹과 낮은 그룹 모두 통계적으로 유의한 자기주도학습준비도 향상을 보였다(p<0.05). 회귀분석 결과 자기주도학습준비도 관련 변수들의 모델 설명력은 41.1%로 높았으며 연령과 수시시험이 자기주도학습준비도와 통계적으로 유의한 양의 상관관계를 보였다(p<0.05). 학습자를 둘러싼 환경이 자기주도적으로 학습할 수 있도록 하는 정도와 적절한 피드백이 주어질 때 자기주도학습 향상에 긍정적인 영향을 미칠 수 있음을 확인할 수 있었다. 암기과목에서 자기주도학습 역량을 이끌어내고 싶은 교수자나 수업설계자들에게 기초자료가 될 수 있을 것으로 기대된다.

          몰입이론을 적용한 프로그래밍 WBI가 학습자의 몰입수준과 학업성취도에 미치는 영향

          채유미,조성환,김성식 한국컴퓨터교육학회 2009 컴퓨터교육학회 논문지 Vol.12 No.1

          Computer programming language learning has an educational effect on improving the high level abilities such as a logical thinking ability and a problem solving ability as well as on understanding a computer working process through the process of programming and debugging tasks. In this study, the Flow Theory is applied for the students to have inner learning motive and continue their learning in the programming language learning. For this, we developed teaching-learning strategies applied by Flow elements, and designed to the WBI. We also applied to the actual teaching-learning field designed WBI and verified the effects on the changes in the learner's Flow level and academic achievement. The result of verification, WBI learning applied by Flow Theory is effective on improving Flow level, making the students have the learning goal and spirit of challenging, forming feedbacks. Also Flow experiences have effect on improving academic achievement(programming ability) through the positive effects on the results of the learning. 컴퓨터 프로그래밍 언어 학습은 프로그래밍과 디버깅 과정을 통해 컴퓨터 작동원리를 이해할 수 있을 뿐만 아니라, 논리적 사고력, 문제해결력과 같은 고차원적 사고능력을 함양시켜주는 교육적 효과가 있다. 본 연구에서는 프로그래밍 언어 학습에서 학습자들의 내재적인 학습 동기를 유발하고 학습을 지속시키기 위한 방안으로 몰입이론을 적용하였다. 이를 위해 몰입의 구성 요소를 적용한 교수 학습 전략들을 개발한 후, 이것을 WBI로 설계, 구현하였다. 또한, 구현된 WBI를 실제 교수-학습 현장에 적용하여, 학습자의 몰입수준 변화와 학업성취도에 미치는 효과에 대해 검증하였다. 그 결과 몰입이론을 적용한 WBI 학습이 학습 목표의식과 도전감, 구체적인 피드백을 이루어 몰입수준 향상에 효과적이었으며, 몰입 경험이 학습 결과에 긍정적인 영향을 끼쳐 학업성취도(프로그래밍 능력)의 향상에 효과적이었다.

          지오텍스타일 봉합 인장강도와 지반의 응력증가분 해석

          채유미,김재홍 한국지반신소재학회 2018 한국지반신소재학회 논문집 Vol.17 No.4

          서해안과 남해안 그리고, 하천유역에는 연약지반을 개량하여 산업시설 공간과 농경지 확보를 위해 토목섬유매트 활용이 많아지고 있다. 광대한 연약한 지반을 개량하기 위한 초기단계로 장비 진입을 위해 토목섬유매트를 포설하고 접합하여 넓은 지반의지지력을 증대시킨다. 토목섬유매트 봉합강도는 원단 인장강도의 50% 정도만 힘을 발휘하고 있어 장비주행성에 융기와 침하등 지지력 저하의 문제들이 발생한다. 본 연구는 여러 가지 토목섬유매트 봉합기술들을 분석하고 각 방법들의 인장강도를 비교분석하였다. 또한 토목섬유매트의 봉합강도를 증가시켰을 때, 상재하중에 의한 지반내의 응력증가분이 감소하는 경향을 수치해석으로 확인하였다. 봉합강도를 60, 70, 80%으로 향상시켰을 때 토목섬유에 의한 지반의 지지력 증가를 확인할 수 있었다. In the west coast, south coast, and river basin, the use of geotextile mats has been increasing to improve the soft ground for making industrial facilities space and farmland. As an initial step to improve the vast and soft ground, the geotextile mats are laid and bonded to increase the bearing capacity of the wide ground for supporting construction equipment. Seam strength of geotextile mats exert a force only about 50% of the tensile strength of the fabric, which causes problems such as uplift and sinking in the soft ground. In this study, various types of geosynthetic matting techniques were investigated and the tensile strength of each method was compared and analyzed. Numerical analysis shows that stress increment in the ground due to the overburden load decreases when the seam strength of the geosynthetics mats is increased. When the seam strength was increased to 60, 70 and 80%, the bearing capacity of ground by geotextile mat was increased.

          Objectives: An ultra dry air environment of nearly ${\leq}2%$ RH is often required in lithium battery factories. The objective of this study is to evaluate the subjective eye, pulmonary, nose, and skin symptoms of workers exposed to ultra-low relative humidity and thionyl chloride. Methods: We recruited 274 workers using a self-reported questionnaire in March 2014. Those who worked in ultra-low relative humidity and with thionyl chloride were identified and their prevalence of symptoms was compared with that of other workers. We excluded white collar workers, researchers and other workers who were exposed to various hazard factors, and finally included 164 workers. Results: There were significant differences in the rate of self-reported eye and skin symptoms between exposure group_1 and exposure group_2. Exposure group_2 experienced more frequent eye, and skin symptoms. Multinomial logistic regression analysis for experience of dry eye symptoms and skin symptoms in exposure group_2 showed that dry eye symptoms (odds ratio [OR], 6.33, 95% confidence interval [CI], 2.19-18.24, p<0.001), and itchiness (OR, 6.45, 95% CI, 1.94-21.43, p<0.01) were the significant variables. The complaints of workers experiencing ultra-low relative humidity and thionyl chloride were high compared with other workers. Conclusion: These findings suggest that exposure to ultra-low relative humidity and thionyl chloride may be associated with more frequent eye and skin symptoms than exposure to ultra-low relative humidity alone. The current precautions to protect workers from the adverse effects of ultra-low relative humidity and thionyl chloride appear to be insufficient, indicating that additional management plans to reduce symptoms should be considered.
