액션러닝방법론에 기반한 창의성프로그램 참여경험에 따른 문제해결의도의 영향에 관한 연구
김승현,박재성,Kim, Soung-Hyun,Park, JaeSung 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.6
This study identified the factors that influence the problem solving intention of students who completed the action learning-based creativity programs based on the theory of reasoned action, and examined the influence relationship between these factors. As a result of the study, first, subjective norms of problem solving had a positive effect on problem solving intention, and second, attitude toward problem solving had a significant effect on problem solving intention. Third, it was found that students who had experience of participating in a patent education program applying the action learning methodology had a positive effect on the relationship between their attitude toward problem solving and their intention to solve the problem. These findings confirmed that in order to enhance the problem-solving intention, which is the basis for creativity of university students, it is important to spread the positive value of problem-solving within the university and to give students a positive attitude toward problem solving.

Due to the limited experimental data on the seismic performance of concrete-encased steel columns, standardized guidelines for nonlinear modeling parameters and acceptance criteria have not yet been developed. This study utilized analytical and numerical methods to predict the nonlinear behavior of concrete-encased steel columns with H-shaped steel sections. The findings of this study have direct and practical implications for the design and evaluation of concrete-encased steel columns. For instance, for concrete-encased steel columns constructed with normal-strength concrete and subjected to low-to-moderate axial load ratios, the yield rotation angle can be determined through fiber-based section analysis and analytical equations, and the nonlinear modeling parameter can be evaluated based on section analysis and the proposed empirical equation. For concrete-encased steel columns with high-strength concrete or high axial load ratios, inconsistencies between section analyses and experimental results are observed. Accordingly, the nonlinear modeling parameter a can be evaluated using the proposed empirical equation. The empirical equation was conservatively developed based on the modeling parameter criteria for reinforced concrete columns in ASCE 41-13.

Social trust as an individual characteristic or societal property?
김승현,김상묵 한국행정학회 2021 International Review of Public Administration Vol.26 No.1
This study aimed to predict individual social trust with both individual- and country-level characteristics. We hypothesized that individual social trust will be affected by human values at the individual level and cultural characteristics at the national level. The hypotheses were verified by a multilevel analysis of data from the World Values Survey Wave 5 (2005–2009) and Wave 6 (2010–2014) covering 64,548 individuals in 45 countries. It was found that among individual values, universalism, stimulation, power, and selfdirection were positively related to individual social trust. Factors that were negatively associated were security and achievement. Among the cultural dimensions, individualism was positively related to social trust, whereas uncertainty avoidance was negatively associated. Among the respondents, those who were older, more educated, and in higher income brackets showed higher levels of social trust. The findings here indicate that social trust is not only an individual property but also a property of society.

A thermodynamic cycle analysis is performed for refrigerator-precooled Linde-Hampson hydrogen liquefiers, including catalysts for the ortho-to-para(o-p) conversion. three different configurations of the liquefying system, depending upon the method of the o-p conversion, are selected for the analysis. After some simple and justifiable models are introduced, a general analysis program to predict the liquid yield and the figure of merit(FOM) is developed with incorporating the commercial computer code for the hydrogen properties. The discussion is focused on the effect of the two primary design parameters-the precooling temperature and the high pressrure of hydrogen. When the precooling temperature is in the range between 45 and 60 K, the optimal high pressure for the maximal liquid yield is found to be in the range between 100 to 140 bar, regardless of the o-p conversion. However, the FOM can be maximized at slightly smaller values of high pressures. It is remarkable to observe that the lower precooling temperatures are favorable since both the liquid yield and the FOM can be obtained without compressing hygrogen to extremely high pressures.

중학교 기술교사의 발명 내용 교수 지식(I-PCK) 중요도 및 수행도 분석
김승현,최유현 한국기술교육학회 2015 한국기술교육학회지 Vol.15 No.3
The purpose of this study is to select compositional domains and content elements of Pedagogical Content Knowledge of Invention and investigate how importantly middle school technology teachers think about the selected elements and at what level their performance is. To achieve the purpose of this study, we examined previous studies to select the compositional domains and the content elements of I-PCK, and seven experts in technology and invention education evaluated the content validity twice. We conducted a survey using a 5-point Likert scale based on the final selection of compositional domains and the content elements of I-PCK. From the results of this study, we could come to the following con clusions: First, according to the results of the analysis of the importance and the performance of I-PCK, the average of the whole importance in the results was 3.81. The average of the whole performance was 3.27, which was above average. In all mid-scale domains, the importance was higher than the performance. Second, we could observe that some elements in the domains, such as ‘the reconstruction of the invention curriculum’ and ‘the creation and utilization of invention education environments,’ need to be improved and that a lot of attention and effort should be made to improve them. Third, current middle school technology teachers generally demonstrate higher performance when they think it is important, but they demonstrate lower performance when they don't. Therefore, we should do additional research about the domains that seem to be of low importance for checking their cognition, and we should seek some ways to promote the performance of invention education if they need cognition improvements. 이 연구의 목적은 발명 내용 교수 지식(Pedagogical Content Knowledge in Invention)(이하 I-PCK)의 각 구성영역과 내용 요소를 도출하고, 중학교 기술교사를대상으로 그들이 도출된 요소에 대하여 얼마나 중요하게 생각하고 있으며 수행 정도는 어떠한지 알아보는 데 있었다. 연구의 목적을 달성하기 위하여 선행연구를 고찰하여 발명 내용 교수 지식(I-PCK) 의 구성영역 및 내용 요소를 도출하고 7인의 기술교육, 발명교육 전문가를 선정하여 2 차례의 내용타당도 검증을 실시하였다. 최종적으로 선정한 I-PCK의 구성영역과 내용요소를 바탕으로 5점 Likert 척도의 조사 도구를 제작하여 설문 조사를 진행하였다. 이 연구의 결과는 다음과 같다. 첫째, 발명 내용 교수 지식(I-PCK)의 중요도 및 수행도 분석 결과 전체 중요도 평균은 3.81점, 전체 수행도 평균은 3.27점으로 보통 수준 이상이었으며 모든 중영역의중요도가 수행도에 비해 더 높았다. 둘째, ‘발명 교육과정 재구성’, ‘발명교육 환경의 조성 및 활용’과 같은 일부 영역에서 개선이 요구되는 요소들을 확인할 수 있었으며 이러한 요소의 개선을 위한 관심과 노력이 경주되어야 한다. 셋째, 현재 중학교 기술교사들은 전반적으로 중요하다고 생각하는 경우에는 수행도가 높지만, 중요하지 않다고 생각하는 경우에는 수행도가 높지 않은 경향을 보이고있다. 따라서 교사들이 낮은 중요도를 보인 영역들에 대하여 추가적인 연구를 통해인식이 적절한 수준인지 파악하고 만약 인식 개선이 필요하다면 중점적으로 개선하여 전체적인 발명교육의 수행도를 증진하기 위한 방안을 강구할 필요가 있다.
