Distance learning at universities has been activated since Covid-19. However, for the lecture evaluation, the questionnaire used in the existing face-to-face education or only partially modified questionnaire is being used, even though they are not proper in the context of distance learning. Therefore, this study derived lecture evaluation questionnaires that are proper for distance learning at universities. Based on the previous studies, we derived the basic questionnaire and verified its content validity by experts. First, the ‘class preparation’ area includes questions like providing sufficient learning materials and redesigning customized distance education classes. Second, the ‘class operation’ area are about notice and advance guidance, time distribution, lecture delivery power, interaction and communication methods, syllabus, lecture contents, progress log and technology. Finally, the ‘class evaluation’ includes questions about appropriate evaluation time and the presentation of clear evaluation criteria. This questionnaire is expected to use as self-evaluation criteria for instructors or as a tool for improving the quality of distance learning in terms of university policy. However, only a preliminary survey was conducted only for some students, so a follow-up study is needed to check the statistical verification of the concepts within the questions.

S-349 : A case of recurrent paragangliomas after MIBG therapy

한송이 대한내과학회 2013 대한내과학회 추계학술대회 Vol.2013 No.1

Pheochromocytoma is a rare tumor that usually develops from one of the body`s two adrenal glands, located above each kidney in the back of the upper abdomen. Paragangliomas was rare extra-adrenal catecholamine producing tumors that are found along the sympathetic and parasympathetic chain, metastatic malignant paraganglioma arries a 5-year survival of 20 to 45%, however histologically, it is difficult to distinguish between benign and malignant paraganliomas with the WHO definition of a malignant paragangliomas being one with metastasis. Our patient, a 66-year-old woman diagnosed extra-adrenal pheochoromocytoma in Rt. retroperitoneum (paraganglioma) and have MIBG treatment 10 years ago. However, the catecholamines level in the urine is increasing and mass detected in right renal hilum and perirenal space.

베이비붐세대의 여가생활과 여가생활만족에 영향을 미치는 요인에 관한 연구

한송이,김세원 한국비영리학회 2019 한국비영리연구 Vol.18 No.1

As baby boomers begin their retirement in 2010, their leisure time has increased and their interest in satisfying leisure activities has been increasing in terms of improving their quality of life. Accordingly, this study examined the socio-demographic characteristics, leisure-related policy satisfaction, and leisure time sufficiency as factors affecting the leisure satisfaction of the baby boomers. The analysis was conducted using data from the 2016 National Leisure Activity Survey conducted by the Ministry of Culture, Sports and Tourism and the Korea Culture and Tourism Institute. A total of 1714 baby boomers were selected among 10,602 men and women aged 15 and over who live in 17 provinces nationwide and regression analysis was conducted. According to the results, the more male, the less female, the more leisure time they realize they have on weekdays and holidays, the more satisfactory the leisure facilities and facilities for leisure and professional staffing. These results suggest the need to expand leisure facilities and deploy professional personnel to support the baby boomers' leisure activities. In order to revitalize the leisure activity of the baby boom generation, In order to promote the leisure activities of the baby boomers, the government and local governments need to build infrastructure and the members of the community should voluntarily participate and lead them to lead the meaningful life of the baby boomers. 베이비붐세대의 은퇴가 2010년부터 시작됨에 따라 여가시간이 증가되었고, 이들의 삶의 질을 향상시키는 측면에서의 만족스러운 여가 행위에 대한 관심이 증대 되고 있다. 이에 따라 본 연구에서는 베이비붐세대의 여가만족도에 영향을 미치는 요인으로 인구사회학적 특성과 여가관련 정책만족도, 여가시간 충분도를 살펴보았다. 이를 분석하기 위해 문화체육관광부와 한국문화관광연구원이 실시한 2016년 국민여가활동조사 자료를 사용하였고, 이는 전국 17개 시도에 거주하는 만15세 이상 남녀 10,602명 중 베이비붐세대 1,714명을 추출하여 회귀분석을 실시하였다. 그 결과에 의하면 여성보다 남성, 경제활동에 참여하지 않을수록, 평일과 휴일의 여가시간이 충분하다고 인지할수록, 특히 여가시설과 여가 전문 인력 시설 확충과 전문 인력 배치에 대해 만족도가 높을수록 여가생활만족도가 높았다. 위의 결과는 베이비붐세대의 여가활동을 지원하기 위한 여가시설 확충과 전문인력 배치가 필요함을 시사한다. 이에 따라 베이비붐세대의 여가활동을 활성화하기 위해 국가와 지자체의 인프라 구축 역할이 필요하며 지역사회 구성원들이 주체가 되어 자발적으로 참여하고 이끌어 나가도록 하여 베이비붐세대의 의미 있는 노년을 보낼 수 있도록 해야 할 것이다.

한송이,박찬우,장재혁,이승환 강원대학교 산림과학연구소 2015 Journal of Forest Science Vol.31 No.4

With the intention to solve environmental problems caused by synthetic plastics from petroleum resources, biodegradable polyurethane foams and thermosetting moldings were prepared from biomass, such as wood and wheat bran by liquefaction method. Biodegradability of these biomass-based polymeric materials was investigated. In activated sludge, polyurethane foams from liquefied wheat bran and thermosetting molding from phenolated wood were decomposed approximately 14% and 29% for 20 days, respectively. One of the wood fungi, Coriolus versicolor was able to grow without supplemental nutrition, only with distilled water and polyurethane foam as a nutrition source. Risk assessments were also conducted and results showed that estrogenicity, mutagenicity, and carcinogenicity were not observed in the extractives of biomass-based polymeric materials.

Phospholipase D activates HIF-1-VEGF pathway via phosphatidic acid

한송이,허정순,김우성,정성근,민도식,정연진 생화학분자생물학회 2014 Experimental and molecular medicine Vol.46 No.-

Growth factor-stimulated phospholipase D (PLD) catalyzes the hydrolysis of phosphatidylcholine (PC), generating phosphatidic acid (PA) which may act as a second messenger during cell proliferation and survival. Therefore, PLD is believed to play animportant role in tumorigenesis. In this study, a potential mechanism for PLD-mediated tumorigenesis was explored. Ectopic expression of PLD1 or PLD2 in human glioma U87 cells increased the expression of hypoxia-inducible factor-1α (HIF-1α) protein. PLD-induced HIF-1 activation led to the secretion of vascular endothelial growth factor (VEGF), a HIF-1 target gene involved in tumorigenesis. PLD induction of HIF-1α was significantly attenuated by 1-butanol which blocks PA production by PLD, and PA per se was able to elevate HIF-1α protein level. Inhibition of mTOR, a PA-responsive kinase, reduced the levels of HIF-1α and VEGF in PLD-overexpressed cells. Epidermal growth factor activated PLD and increased the levels of HIF-1α and VEGF in U87 cells. A specific PLD inhibitor abolished expression of HIF-1α and secretion of VEGF. PLD may utilize HIF-1-VEGF pathway for PLD-mediated tumor cell proliferation and survival.
