노출시간 및 자극유사성에 기인한 유아의 시각 Habituation
이선인 고려대학교 행동과학연구소 1979 行動科學硏究 Vol.4 No.1
만 4個月된 幼兒의 視覺反應 統合過程이 한쌍의 둥근 눈(Bull's eye) 形態의 刺戟과 다른 한쌍의 옆으로 된 줄무늬 形態(striped pattern)의 刺戟을 單一提示板 위에 提示함으로써 연구되었다. Jeffrey(1968)의 連鎖 해비츄에니션 假設에 따른 豫測은 露出 初期에는 幼兒가 刺戟을 連鎖的으로 훑어보는 視覺行動이 類似한 刺戟쌍에 局限될 것이나 類似한 刺戟쌍에 대한 注意가 減少됨에 따라 선택이 덜 되던 刺戟이 反應形態로서 統合되어질 것이다. 連鎖的인 세 번의 注視를 單位로 한 測定値에 의하면 類似한 刺戟쌍에 局限되었다 注意 反應이 露出 時間에 ‘따라 有意味하게 減少되는 반면, 初期에 低反應率을 보였던 두 개의 類似 刺戟과 하나의 非類似 刺戟에 대한 세 개의 連續的 注視 反應 形態가 有意味하게 增加되었다.

PEM 수전해 Cathode 액상조건과 기상조건에서 MEA 내구성 비교
이선인,김영숙,추천호,오소형,박권필 한국공업화학회 2020 한국공업화학회 연구논문 초록집 Vol.2020 No.-
PEM(Proton Exchange Membrane) 수전해는 PEMFC와 유사하게 귀금속 촉매와 고분자 전해질을 이용하여 물을 전기분해하여 양극에서 산소, 음극에서 수소를 발생시킨다. PEM 수전해는 화석연료를 이용한 수소 생산과는 다르게 환경 오염이 없기 때문에 유망하다고 생각되나, 내구성이 아직 확보 되지 않은 문제점이 있다. 신재생에너지의 잉여 전력을 활용한 수소 생산 방법으로 연구가 진행되고 있으나, 다양한 조건에서의 내구성에 대한 자료가 부족한 상황이다. 본 연구에서는 수전해 셀(Cell) Cathode의 액상 및 기상 조건에 따른 PEM 수전해 내구성에 대해 연구하였다. 내구성 평가조건으로 온도와 전압, 액상 및 기상 조건을 변화시키면서 고분자막과 전극의 열화정도를 분석하였다. PEM 수전해 MEA 열화는 I-V, Impedance, CV, FER 등을 이용해 분석했다. Cathode를 액상 조건에서 구동하였을 때 Radical 발생속도가 감소해 고분자 막 내구성이 향상됨을 보였다.

이선인 中央大學校 韓國敎育問題硏究所 1995 韓國敎育問題硏究所論文集 Vol.- No.10
One hundred and ninety two first graders, consisted of equal numbers of boys and girls, participated in the present study. After taking an intelligent test, children who obtained respectively high scores and low scores on the test were given false statements(feedback) irrespective of their true scores in order to temporarily induce either an increase in children's self-esteem or a decrease in their self-esteem. children were given an opportunity to play a series of card games during which they could cheat on some trials. It was expected that children with high scores on the intelligence test would display more dishonest behaviors than children with low scores, and that boys would cheat more than girls would do. The present study also examined whether or not the differential levels of the induced self-esteem in the first graders affect on dishonest behavior of the children. The results from a 3-way ANOVA indicated that there was no significant effect of intelligence, measured by the test scoring either high or low, on the display of children's dishonest behavior. However, there was significant sex differences between the boys and the girls. The boys showed dishonest behavior more than the girls did. Finally, there was no significant effect of differentially induced self-esteem on dishonest behaviors of the first graders. The findings are interpreted in terms of previous research on children's dishonest behaviors as supporting the assumption that boys tended to cheat more than girls did.

The present study examined developmental changes as well as sex differences in children's dishonest behavior. Children were participated in a series of card games during which they could cheat on some trials. Subjects were 162 children, consisting of equal numbers of boys and girls, evenly divided into Kindergarteners, first grad- ers, and second graders. Data from first and second graders were drawn from a previous research and were combined with those obtained from kindergarteners. From a 2-way ANOVA, main effects of grade and sex were obtained. Futher analyses indicated, as expected, that second graders cheated more than did kinder- garteners and that second graders cheated more than did first graders. No signifi- cant differences were found between kindergarteners and first graders. Regarding sex differences, second-grade boys exhibited more dishonest behaviors than did sec- ond-grade girls. No sex differences were found in kindergarteners and first graders. Findings are discussed in terms of previous research on children's moral judgments and dishonest behaviors as supporting the assumptions that children's dishonest be- havior increase with age or grade and that boys tend to cheat more do girls.

STI for SDGs 역량분석 및 글로벌 협력전략 -국가연구개발사업 분석 중심으로-
선인경(Inkyoung Sun),김왕동(Wangdong Kim),장용석(Yongsuk Jang),박환일(Hwanil Park),유지영(JiYeong Yoo),김소은(Soeun Kim),안지용(Jiyong An),강신애(Shinae Kang) 과학기술정책연구원 2021 정책연구 Vol.- No.-
Given all countries’ commitment to the Sustainable Development Goals (SDGs), it has been emphasized that countries should try to accelerate the achievement of the SDGs by utilizing Science, Technology, and Innovation (STI) as a key tool. Korea has lagged in setting the national-level STI for SDGs directionality and integrating STI and SDGs. In contrast, major countries such as Japan, Germany, and China have proactively framed their STI R&D investment in the SDGs and actively promoted their contribution to solving global challenges in the international community. Considering the urgency of the STI for SDGs strategy development, this research conducts a quantitative analysis on STI for SDGs activities in Korea, mainly focusing on the national R&D programs for the recent three years. Despite quite a low level of understanding about SDGs among Korean scientists and engineers, it finds out that most public research in Korea shows a high level of STI relevance to solving the SDGs targets. Among the 17 SDGs, research on the SDGs 8 (energy), 9 (industry, infrastructure, and innovation), and 11 (sustainable city) are the most popular in Korea, while research on the SDGs 1 (poverty), 4 (gender equality), and 10 (inequality) are the least. The most general-purpose research and technology, which can be defined as a multi-SDGs contributor with a potentially high impact on the SDGs achievements, are disaster and safety research, climate, renewable energy, agriculture and fisheries, big data, and artificial intelligence, etc. This research develops four types of STI for SDGs strategies based on the SDGs implementation level and STI capacity defined as R&D inputs and outputs of Korea. Its results suggest that the Korean government seeks strategically a selective approach rather than a comprehensive approach to deal with all 17 SDGs. As for the weak areas such as SDGs 5 (gender equality), 10 (inequality), 13 (climate change), 14 (ocean ecosystem), 15 (land ecosystem), and 17 (global partnership), the government is recommended to take the “Global Inbound Strategy” for fostering STI for SDGs capacity through accelerating international STI collaboration. On the other hand, the “Global Outbound Strategy” is recommended for the strong areas such as the SDGs 4 (education), 9 (industry, infrastructure, and innovation), and 11 (sustainable city) to utilize so-called “Korea-made STI” for contributing to the SDGs achievement of other countries and the international community as a whole. In conclusion, the research calls for timely action for the national-level STI for SDGs strategy development, keeping in mind that the domestic challenges are eventually universal challenges facing all countries.
