  • In this study, volunteer experience(motive, durability, satisfaction, content) was set up as an independent variable, career maturity degree(determinacy, involvement, independence, tendency) was set up as a dependent variable, and the average difference and effect of the sub factors for each of them were reviewed. For this purpose, questionnaires were performed with 519 students at the middle schools and high schools in Busan. With 376 students having volunteer experiences among them, an analysis was done to find out the effect of volunteer experience on career maturity. The results of this study are as follows: First, whether having volunteer experience or not affected the career maturity among youths. That is the group with volunteer experience had higher level of interest, involvement and value in career and jobs than the group without them. Second, it showed that volunteer experience affected career maturity among youths. Specifically, career maturity was higher as their motive for volunteer activities was selfish, their satisfaction for volunteer activities was higher and they had more volunteer activities.

  • The purpose of this study was to examine how group argumentations mediated individual arguments by analyzing physics teachers' group argumentation and individual follow-up written arguments. Five in-service physics teachers participated in this study, two middle school and three high school teachers. The topics of argumentation included physics topics and pedagogy of them. Findings showed that the teachers constructed much more elaborated individual written arguments than group argumentation, which seemed to be resulted from different perceptions of teachers' verbal and written argumentations. Also, in their written arguments the teachers selectively utilized their colleagues' ideas shared during group argumentation. Lastly, teachers' argumentation showed different features between topics of physics and physics pedagogy. These differences were related to their orientations toward argumentation about content knowledge and teaching. These findings shed light on a productive physics teacher professional development in argumentation.

  • 최근 들어 기업가적 활동을 촉진하는 데 있어 무엇보다도 여성의 경제활동 참여와 사회안전망 구축의 필요성이 제기되고 있는바, 본 연구에서는 사회화경험과 기업가 활동의도의 관계에 대한 맥락적 차이 규명에 초점을 두고, 이들 관계에 대한 성별의 조절 효과와 사회안전망의 삼원조절효과에 대해 규명하고자 한다. 본 연구 목적은 다음과 같다. 첫째, 사회화경험(창업경험, 기업가정신 교육경험)이 기업가 활동의도에 미치는 효과를 규명하고, 이들 관계에 대한 성별의 조절효과를 검증한다. 둘째, 사회화경험 및 기업가정신 교육과 기업가 활동의도의 관계에 대한 성별 조절효과가 사회안전망과 같은 국가 맥락적 차이가 존재하는지에 대해 삼원상호작용 분석을 통해 검증한다. 상기 연구목적을 달성하기 위해 본 연구는 (재)한국청년기업가정신재단에서 제공한 글로벌 기업가정신 추세 리포트(GETR) 자료를 활용하였다. GETR자료는 한국을 포함한 총 20개국(한국, 일본, 중국, 인도네시아, 인도, 싱가포르, 런던, 독일, 러시아, 덴마크, 핀란드, 영국, UAE, 이스라엘, 남아공, 터키, 이집트, 미국, 브라질, 칠레, 호주)을 대상으로 국가별 최소 2,000명을 표본으로 선정해 설문조사가 이루어진 자료이며, 유효 응답자 기준 총 40,388명이 설문에 응답하였다. 그러나 자료 검증과정에서 전체 응답자 중 2,506명이 불성실 응답자 및 이상치로 확인되어 최종 분석과정에서 삭제되었다. 따라서 37,882개의 표본이 최종 분석에 활용되었으며, 여성 17,997명 (47.5%), 남성 19,885명(52.5%)으로 확인되었다. 분석 도구는 Hayes의 Process를 활용하여 사회화 및 교육, 성별, 성별 격차의 삼원상호작용 효과에 대한 분석이 이루어졌다. 분석 결과, 첫째, 창업경험 및 기업가정신 교육경험은 기업가 활동의도에 유의한 영향을 미치는 것으로 나타났다. 둘째, 이들 관계에 대한 성별 조절효과를 살펴본 결과, 성별 조절효과는 기업가정신 교육경험과 기업가 활동의도의 관계에 대해서만 유의한 영향을 미치는 것으로 확인되었다. 구체적으로, 기업가정신 교육경험이 기업가 활동의도에 미치는 긍정적 효과는 여성이 남성보다 더 강한 것으로 나타났다. 마지막으로, 사회안전망의 삼원조절효과를 분석한 결과, 창업경험과 기업가 활동의도의 긍정적 관계는 여성이 남성보다 더 강한 것으로 나타났는데, 이러한 효과는 사회안전망이 높은 집단에서 더 높게 나타나는 것으로 확인되었다. 즉, 과거 창업경험이 있는 여성은 사회안전망이 높다고 인식할 경우 과거 창업경험이 있는 남성보다 기업가 활동의도가 더 많이 증가하는 것이다. 이와 관련된 논의는 본문에 제시하였다.

  • Aim: This study investigated the association between leisure activities and cognitive impairment in Korean community-dwelling older adults. Methods: Among participants of the 2017 National Survey of Older Koreans, 10,055 (male=4,277, female=5,778) were included in this cross-sectional study. To better identify the association between late-life cognition and leisure activities, individual leisure activities were categorized into 3 types including productive, consumptive, and unclassified activities. Multivariate logistic regression analysis was performed to assess the association between participation in leisure activities and cognitive impairment when controlling for possible covariates evidenced by previous studies. Results: Male participants were more likely to be cognitively impaired than female ones with significant differences in all the covariates. After controlling for confounding variables, involvement in productive leisure activities was found to be associated with cognitive function in both male and female groups, along with age, educational level, depressive symptoms, subjective hearing problems, and occupational status. Conclusion: Involvement in productive leisure activities might be associated with decreased risk of cognitive impairment in later life. Appropriate strategies to encourage older adults to participate in productive leisure activities should be established to help them maintain their cognitive function.

  • The purpose of this study is to investigate what kind of activities by specialized highschool students who have a sense of learned helplessness do after school, and then to inquire if there would be any of differences between their school activities and after school activities. The students in J specialized highschool for vocational education, located in D city participated in the program of improving learning motivation for students with learned helplessness. We selected 15 out of them as the subjects who were judged to be suitable for this study through 'Convenience sampling'. The research methods of this study is qualitative research methods by observation and in-depth interviews. The results are as in the following. First, daily activities after school of the specialized highschool students with learned helplessness can be divided into 3 groups; leisure activities, learning activities, and sustenance activities. Most of the students spend a lot of time doing leisure activities such as playing with a computer, watching TV, doing something with their friend, and killing time. Secondly, the character of daily activities after school of the specialized high school students with learned helplessness is different from that of the students' school activities connected with their daily activities after school. Based on the results we need to consider the character of the students' daily activities after school so as to help the students with learned helplessness, especially in specialized school.

  • 흑점과 오로라의 역사적 기록은 단편적이고 관측 빈도에 의존하는 문제도 있지만 과거 태양활동의 실제 모습을 보여주는 중요한 자료이다. 또한 지구 대기에 유입된 cosmic ray에 의해 만들어지는 14C이나 10Be 그리고 18O와 같은 동위원소들이 나무 테나 polar ice 그리고 바다의 퇴적물 등에 축적되어 나타나는 Proxy data와 함께 과거 태양의 활동뿐만 아니라 지구의 자기장이나 기후 변화 등을 연구하는데 중요한 지표로 사용된다. 최근 태양의 활동과 지구 기후 변화의 관계에 대해 특별히 많은 관심이 집중되고 있으며 많은 연구가 진행되고 있다. 이 연구는 우리 역사서에 실린 흑점과 오로라의 역사적 기록 및 태양의 proxy data를 함께 비교하여 지난 1000년간 태양활동에서 나타난 특징들, 즉 흑점의 출현과 오로라 발생사이의 밀접한 관계 및 태양활동의 장단기 주기변화 그리고 Maunder Minimum과 같은 최대 극소기 때 보이는 기후 변화와 태양활동의 특징 등에 대해 논의해 보고자 한다.

  • 기후와 인간 활동의 변화는 하천의 유량을 변화시키는 중요한 요소들 중 하나이다. 하천관리를 위해서는 이 요소들의 긍정적인 영향과 부정적인 영향이 하천에 얼마나 많은 영향을 끼치고 있는지 수치화하여 관리해야한다. 또한 상류에서의 기후와 인간 활동에 의해 변화된 유량은 하천 하류까지 전달되어 적지 않는 영향을 미치고 있다. 효과적인 하천관리를 위해서는 유역 내 기후와 인간 활동에 의해 변화된 유량과 하류하천에 미치는 영향을 정량화하여야 한다. 본 연구에서는 하천에서 기후와 인간 활동에 의한 유량 변화를 정량화 하고 그 요소들이 상류에서 하류에 얼마나 많이 전달이 되는지 분석하였다. 본 연구 결과 수리구조물이 설치되어 있는 하천에서는 인간 활동에 의한 유량변화량이 크게 나타났다. 상류의 수리구조물에 의한 영향은 하천 하류에도 크게 전달되는 것으로 분석되었다. 또한 기후적인 요인에 의해 유량의 변화가 큰 지역은 그 외 지역보다 자연 재해에 의한 피해 위험도가 높다고 판단된다. 본 연구의 결과는 미래의 효과적인 수자원관리를 결정하는데 중요한 정보를 제공해줄 수 있을 것이라 기대된다.

  • This article presents a case study in which three middle school students developed models in modeling activity using a tool. We research the interaction of model development process and the activities operating a tool in the modeling. And we investigate whether students are able to create generalizable model, after a tool mediates students' thought process and students internalize the perceptive activity operating a tool. The analysis of our case study led to three results. First, as students were able to integrate perceptive activity operating a tool and cognitive activity, they reasoned about the relationships among changing quantities and developed the model. Second, students corrected and refined developed models with reflecting the perceptive activity operating a tool. Third, as students internalized perceptive activity, students were able to create generalizable model, which is a graph of height as a function of the amount of water that's in the beaker.
