조영선(Jo, Young-Sun),김종진(Kim, Jong-Jin) 한국주거환경학회 2010 주거환경(한국주거환경학회논문집) Vol.8 No.2
The purpose of the study is to establish a solving model of unsold houses(apartment) in Korea. To do so, we have conducted a survey on the experts of the housing markets with a view to establish an AHP (multi-layered decision making model) to calculate an effective and efficient solution for the unsold houses. The conclusions and the implication of this study are as follows; Among the five major categories, the economic supports gained the highest value in its importance, followed by the facilitation through legal or regulatory supports, roles by the public sectors, roles by the private sectors, and the marketing. This implicates that the experts view the economic subsides as the most effective solution for the current problem of the unsold houses, and thought the legal and regulatory supports also important. On the other hands, the roles of the private sectors and the marketing received less attention in terms of their importance, which means that as the problem of the unsold houses is a combined result of various factors, such as, not only the problem of over-supply but also the financial, and the affordability of the houses for its potential purchasers. The effort of the private sector alone is no enough to cope with these factors, and the conventional marketing and promotion would not help to mitigate the situation, as they view the matter.

청소년의 진로정체감의 종단적 변화 모형 : 코호트 연계 설계를 활용하여
조영선(Yeong Seon Jo),장유나(Yu Na Jang),조영일(Young Il Cho) 한국자료분석학회 2018 Journal of the Korean Data Analysis Society Vol.20 No.1
본 연구는 한국아동·청소년패널조사(KCYPS)의 초1, 초4, 중1패널자료로 중·고등학생의 진로정체감에 대한 종단적 변화 형태를 확인하기 위해 잠재성장모형을 분석하고, 초4와 중1패널 간의 차이를 검증하기 위해 회귀분석을 실시하였다. 더불어 시간, 비용 등 현실적인 제한을 극복할 수 있는 코호트 연계 설계 기법을 통해 실제 자료에 이를 적용하는 절차를 설명하며 발생할 수 있는 오류에 대해 증명하였다. 먼저 코호트 연계 설계를 적용하여 생성한 중1부터 고3까지의 진로정체감에 대한 하나의 코호트자료를 분석한 결과, 선형적인 종단적 변화 양상을 보였다. 다음으로 초4와 중1패널코호트 간의 차이를 검증한 결과, 시작값은 중1패널이 더 높았으나 선형 변화율은 초4패널이 더 가파른 증가세를 보이는 코호트 효과가 나타나, 초4와 중1패널코호트 간에 서로 다른 특성을 보임을 확인하였다. 두 가지 결과를 비교함으로써 코호트 연계 설계를 적용할 경우에 두 코호트자료 간의 차이검증을 통해 코호트 효과가 없음을 사전에 확인하는 절차가 필요함을 입증하였다. 또한 초4와 중1패널 코호트 간의 차이는 우리나라 교육과정의 변화와 관련되므로, 진로탐색활동 및 진로지도 등을 하는 자유학기제와 같은 교육과정을 활성화하여 청소년이 지속적으로 진로정체감을 형성할 수 있는 기반을 마련할 필요성을 제기했다. In this study, latent growth curve model analysis was conducted to identify the longitudinal changes in the career identity of adolescents using the data of KCYPS . And regression analysis was conducted to verify the difference between the e4 and m1 panel. In addition, cohort sequential design was introduced as a research technique that can overcome realistic limitations such as time·cost. It describes the procedure for applying it to the actual data and proves the errors that may occur. First, the cohort data for career identity from middle school 1st to high school of the cohort sequential design were analyzed and showed a linear longitudinal change pattern. Second, the m1 panel s initial point (intercept) was higher than e4 panel, but e4 panel s linear change rate (slope) was more steeper than m1 panel (cohort effect). By comparing the two results, it is proved that there is a need to confirm the absence of the cohort effect by verifying the difference between two cohort data when the cohort sequential design is applied. Also the difference between the e4 and m1 panel is related to the changes in the education process of Korea. It is necessary to establish a base for adolescents to continuously form career identity by activating the education process such as the free semester system.

중학교 기술.가정교과 식생활 단원에서 창의핵심역량을 적용한 PBL수업에 대한 형성적 연구
조영선(Cho, Yuong Sun),김지숙(Kim, Ji Suk),조미나(Jo, Mi Na),김정겸(Kim, Jeong Kyoum) 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.3
목적 본 연구에서는 중학교 기술⋅가정교과 ‘가족의 안전한 식생활’ 단원을 중심으로 창의핵심역량 기반의 PBL 수업모형을 적용한 후 형성적 연구방법론에 따라 수업의 효과를 검증하고자 하였다. 방법 이를 위하여 대전 소재 중학교 2학년 학생 92명을 대상으로 PBL 수업을 실시하였고, 창의핵심역량과 PBL 수업 만족도를 측정하였다. 또한 서술형 문항과 자기성찰 보고서를 통해 창의핵심역량을 적용한 PBL 수업모형이 적절했는지와 학생들의 경험은 무엇이었는지를 알아보고, 수업의 강점, 약점, 개선점을 분석하고자 형성적 연구를 실시하였다. 결과 본 연구의 결과에 따르면, 창의핵심역량 기반의 PBL 수업 만족도는 전반적으로 높게 나타났으며, PBL 수업에 대한 학생들의 경험은 ‘다양한 삶의 방향을 탐색하고 경험하다’, ‘함께 하는 공동체의 즐거움을 맛보다’, ‘친구와 협력하여 문제를 해결하다’ 등이 있는 것으로 나타났다. 형성적 연구를 통해 분석한 수업의 강점, 약점, 개선점은 다음과 같다. 먼저, PBL 수업에서의 강점은 강의식 수업에 비해 학습자의 동기 및 흥미유발에 효과적이며, 적극적이고 자기주도적으로 문제를 해결하고자 하며, 협동하고 토론하면서 결과물을 만들어 간다는 점이다. 반면, 약점으로는 PBL 수업에 대한 이해(경험 부족)가 다소 부족하고, 문제해결을 위한 다양한 방식의 체험학습과의 연계가 필요하다는 점이 드러났다. 이에 따른 개선점으로는 PBL 수업에 대한 이해를 돕기 위한 사전교육을 실시하고, 수업 안내를 명확하게 하여야 한다는 것이다. 결론 중학교 기술⋅가정과 ‘가족의 안전한 생활’ 단원을 중심으로 창의핵심역량 기반의 PBL 수업은 학생들의 수업 만족도를 높이고 긍정적인 태도 형성에 영향을 미치는 것을 알 수 있다. 이는 기술⋅가정과 교과목표를 달성하고 수업의 효과를 극대화하기 위한 방안을 탐색하는데 시사점을 제공하는 것이다. 따라서 향후 지속적인 PBL 수업 개발 및 적용을 통해 학생들의 창의핵심역량을 높이고 능동적인 학습 참여를 이끌어내는 것이 중요하다. Objectives In this study, after applying the PBL instructional model based on the core creative competency centering on middle school technology and home and the ‘safe eating lifestyle of the family’ unit, the effect of the instruction is verified according to the formative research methodology. Methods For this purpose, PBL classes were conducted for 92 second-year middle school students in Daejeon, and creative core competency and PBL class satisfaction were measured. In addition, a formative study was conducted to find out whether the PBL class model that applied the core creativity competency was appropriate and what the students experiences were, and to analyze the strengths, weaknesses, and points of improvement through descriptive questions and self-reflection reports. Results According to the results of this study, satisfaction with PBL classes based on creative core competency was found to be high overall, and students experiences with PBL classes showed that ‘explore and experience various directions of life’ and ‘the joy of a community together’ It was found that there were ‘to taste’ and ‘to solve problems by collaborating with friends’. The strengths, weaknesses, and points for improvement of classes analyzed through formative research are as follows. First, the strengths of PBL classes are that they are effective in stimulating learners motivation and interest compared to lecture-style classes, that they try to solve problems positively and self-directed, and that they create results while collaborating and discussing. On the other hand, as weaknesses, it was revealed that the understanding of the PBL class(lack of experience) was somewhat lacking, and that it was necessary to link with experiential learning in various ways to solve problems. As an improvement point, it is necessary to conduct pre-education to help understand the PBL classes, and to make the classes guide clear. Conclusions It can be seen that PBL classes based on creative core competencies, centered on middle school technology, home and ‘safe eating lifestyle of the families’, increase students’ class satisfaction and affect positive attitudes. This is to provide implications for the exploration of ways to achieve technical, family and syllabus goals and maximize the effectiveness of classes. Therefore, it is important to increase students creative core competencies and induce active learning participation through continuous development and application of PBL classes in the future.

중심성 폐암 발견에 있어 협대역 내시경의 임상적 유용성
박진경 ( Jin Kyeong Park ),조영선 ( Young Sun Jo ),장세진 ( Sae Jin Jang ),박영수 ( Young Soo Park ),최창민 ( Chang Min Choi ) 대한결핵 및 호흡기학회 2010 Tuberculosis and Respiratory Diseases Vol.68 No.1
Background: Lung cancer is usually diagnosed at an advanced stage, resulting in a poor prognosis. The detection of these lesions at an earlier stage would be a clear benefit to patients. However, it is extremely difficult to detect carcinomatous lesions in the bronchial mucosal sites during a routine bronchoscopy. Methods: This study employed a novel optical technique, known as narrowband imaging (NBI), which allows noninvasive visualization of the microvascular structure of an organ`s surface using reflected light. Results: Narrow band imaging was performed on 10 patients who were radiologically suspicious or had a high risk of lung cancer. The median age of the patients was 57.5 years (range, 44∼81 years), and 80% of the patients were male. All lesions showed a microvascular proliferation pattern (dotted, tortuous and abruptly ending vessel) on the magnified NBI. Two lesions were confirmed histologically to be adenocarcinoma and the remaining lesions were squamous cell carcinomas. Two lesions were confirmed histologically to be a carcinoma in situ. Conclusion: NBI is a promising and potentially powerful tool for identifying carcinomas at an earlier stage or a central lesion during a routine bronchoscopy examination.
