최근 세계적인 기상이변으로 국지적인 대설과 한파의 발생이력이 증가하고 있다. 특히 최근 2018년 1월 8일 미국에 100년만의 한파로 인해 체감온도가 영하 69도까지 떨어지고, 우리나라에서도 같은 해 2월 8일 제주도 폭설과 한파로 인해 교통이 마비되는 피해가 발생한 것으로 알려져 대표적인 겨울철 자연재해인 대설 피해에 대한 관심이 증가하고 있는 추세이다. 이로 인해 대설 피해예측 및 저감에 대한 연구가 다수 진행되고 있으나, 시 군 구 별 과거 피해이력이 적고, 피해가 발생한 지역과 관측소 사이의 거리가 멀어 정확한 피해예측이 어려운 상황이다. 따라서 본 연구에서는 대설피해에 영향을 미치는 변수들의 데이터를 수집한 뒤 랜덤포레스트를 이용하여 대설피해액을 범주형으로 구분하고, 어느 범주에 포함되는지 예측 및 적용성을 검토하였다. 현재 과거 피해자료의 부족, 과거 피해 발생 환경과 현재 피해 발생 환경의 차이, 대설로 인해 피해가 가장 많이 발생하는 비닐하우스 설계 기준의 변화 등으로 인해 예측 정확도가 높지 않았다. 따라서 대설피해 발생지역의 정확한 기상자료가 확보되고, 변수로 사용한 데이터의 최신화가 진행된다면 본 연구결과의 정확도 향상과 대략적인 대설피해규모 예측이 가능 할 것으로 기대된다.

본 연구는 스타트업이라 구분되는 기업의 구성원을 대상으로 그들의 혁신행동에 미치는 영향 요소를 파악하고자 하였다. 이를 위해 긍정심리학에서 중요한 변수로 다뤄지는 그릿(Grit)과 스타트업에서 특히 중요시 여겨지는 실책관리문화 변수를 중심으로 혁신행동에 미치는 영향을 살펴보았다. 그릿은 스타트업 구성원의 인내에 대한 노력, 조화열정, 상황적응력의 세 변수로 정의하였으며 실책관리문화와 더불어 스타트업 구성원의 혁신행동에 미치는 영향을 살펴보았다. 본 연구를 위해 기술창업 기반 7년 이내 스타트업 재직자를 대상으로 2023년 12월부터 2024년 1월까지 설문조사를 진행해 유효한 305개의 샘플을 확보하였다. 연구모델 분석을 위해 SPSS 24 통계 패키지를 활용하여 그릿과 혁신행동과의 관계 및 실책관리문화와 혁신행동 관계를 분석하였다. 분석결과 그릿의 3가지 변수인 인내에 대한 노력, 조화열정, 상황적응력은 스타트업 구성원의 혁신행동에 정(+)의 영향을 미쳤으며 실책관리문화 또한 스타트업 구성원의 혁신행동에 정(+)의 효과를 나타냈다. 하지만 통제변수로 활용된 성별과 연령은 혁신행동에 유의미한 영향을 미치지 않았다. 본 연구는 스타트업에게 매우 중요한 혁신행동에 영향을 미치는 변수들을 규명하고, 스타트업 구성원의 개인적 특성과 문화적 특성이 혁신에 어떤 영향을 미치는지 파악한데 의의가 있다고 하겠다. 본 연구 결과의 의의는 스타트업 혁신행동에 미치는 새로운 변수들을 규명했다는데 있다. 하지만 7년 이내 초기 창업 기업을 대상으로 305명이라는 제한된 표본으로 연구를 진행했다는 점이 향후 스타트업 범주 및 표본 확대를 보완하여 후속 연구의 확장이 필요하다고 판단된다. 또한, 그릿과 실책관리문화 외에 혁신행동에 대한 영향 변수의 규명이 필요할 것으로 사료된다.

2000년대 이후 기업의 경제적 이익을 위한 본연의 성과를 성취하기 위해서는 영리적 이익추구 이외에도 기업 내외부의 관여된 활동 범주 내에서 투자자, 소비자, 시민단체 그리고 노동조합등에 사회적책임(Corporate Social Responsibility:CSR)의 중요성이 점차 커져가고 있다. 이 중 사회적책임과 조직 내 구성원들의 조직유효성의 영향에 대한 다양한 선행논문이 있었으나, 지역으로 세분화하여 분석한 연구가 상대적으로 미비하였다. 이에 따라 강원도를 한정한 사회적책임이 조직신뢰, 조직몰입, 조직시민행동에 미치는 영향을 분석하여 강원도 소재 기업들의 사회적책임에 대한 기반적 자료로써 활용될 것으로 여겨진다. 이를 확인하기 위해 본 연구는 강원도 소재 기업에 종사하는 구성원들을 대상으로 자료를 수집하여 총 186부의 표본을 활용하였다. 검증결과 사회적책임이 조직신뢰, 조직몰입이 긍정적인 영향을 미치나 조직시민행동에 부분적으로 채택되었으며, 조직신뢰는 조직시민행동에 긍정적 영향을 미치고 조직몰입은 조직시민행동에 부분적으로 영향을 미치는 것으로 연구되었다. 본 연구는 선행논문에서 밝힌 사회적책임이 조직신뢰, 조직몰입, 조직시민행동에 미치는 영향에 대해서 지역을 한정해서 연구했으며, 분석결과 강원도 지역 내 사회적경제기업들이 다수 포진되어 있으며, 공동체성이 높기 때문에 사회적책임이 조직 유효성과 조직시민행동에 영향을 미치는 것으로 나타났다.

The purpose of this study was to investigate how a teaching approach influences student's ability of classification at the brain level. Twenty four healthy and right-handed college students participated in this study, which investigated a brain plasticity associated with category-generation and -understanding in classification learning. The participants were divided into one of two groups, one each for category-generation and -understanding learning programs, which were composed of twelve topics taught over a twelve-week period. To measure the change in student competence and brain activations, a paper and pencil test and an fMRI scanning session were administered before and after the training programs. Unlike the understanding group, the generation group showed significant changes in classification ability quotients and learning-related brain activations (cerebral cortex and basal ganglia were increased and prefrontal cortex and parahippocampal gyrus were decreased). Nevertheless, the understanding group showed an increased activation in the cerebral cortex and parahippocampal gyrus and a decreased activation in the right prefrontal cortex and cerebellum. Therefore, it can be concluded that teaching styles could influence students' brain activation patterns and classification ability. The results might also be used to develop a brain-compatible science education curriculum.

We studied aspects of secondary school science teachers in the Chonbuk province concerning their science-related attitudes using the several measuring tools. We applied the multiple comparison to twelve factors at the science teachers 'backgrounds and analyzed the discrepancy in group levels. Science teachers feel half-hearted for the attitudes related to science teachers show a high correlation between the attitudes toward science and the scientific attitudes. We examined the tendency to the science-related attitudes of science teachers having various backgrounds within 5 percent differences of P-value. The contented teachers for their occupations marked higher than the other teachers in the tendency to the science-related attitudes, and the attitude-score of the science teachers graduated from regular colleges also marked higher than the teachers from the training institutes or the different majors. We have investigated the teachers just in Chonbuk province, but we should recognize that the scores in both the perception and the teachers are not improved comparing with the before-studies of Lee(1985), Park(1993), etc. As a result, the development of measuring tools which teachers can examine themselves as their features is needed and the educational systems to specialize the science education should be improved through the various programs for teachers' training courses.

The purpose of this study is to conceptualize the process of formation by the exploration of the lives of professional golfers who grow to excellent sports leaders, categorize the concept and suggest models between categories. In order to reveal in depth the change process of the job formation, the 'grounded approach' as a qualitative study was used as a the methodological frame of this study, and snow sampling, one of nonrandom sampling was used for the selection method of the study participants. 10 study participants who are able to make positive self-expression and talk with the researcher were selected. Through grounded approach appropriate for this process research, this study could acquire following results. First, through the casual condition that is the exploration of the lives of professional golfers growing to excellent sports leaders, it connected to the central phenomena of professional instruction methods and education belief as golf leaders. In this process, the changes as new experiences for the charm of the new job and relationship formation influence as the function of a contextual condition. In addition, golf leaders tried to become a more completed golf leader through self-efforts for development and expertise attainment according to the their own situations as well as belief, and they have established the lives of firm golf leaders through the process. Second, as a result of the changes of their lives as professional golfers growing to excellent sports leaders, the paradigm of grounded approach which is abstracted as total 141 concepts, 17 subcategories, and 11 superordinate categories were composed.

The purpose of this study is to investigate high school students' geographic misconceptions and their mechanisms of formation. Three main theories explaining why students develop misconceptions exist: 1) framework theory, 2) p-prim(phenomenological primitive) theory, and 3) categorization theory. This study chose three target geographic concepts, or, 1st and 2nd mountain ranges, secondary central business district and satellite city, and the Nopsae wind and the F$\ddot{o}$hn phenomenon. Then, this research explored students' typical misconceptions regarding these concepts and attempted to examine which theory explains the misconception forming processes most well. As a result, the following misconceptions were found. First, students understood that the numbers 1 and 2 denote the order of the formation of mountain ranges. Second, despite differences in their main functions, students tended to subsume the secondary central business district and satellite city under one functional category. Third, students believed that the Nopsae wind and the F$\ddot{o}$hn phenomenon are identical in hierarchy. This study explained students' creation of these misconceptions by applying the categorization theory in which students located a concept in an inappropriate location of an ontology tree.

This study investigated the response time and patterns of categorical perception of the wh-scope of an embedded clause with the non-bridge verb, "gung-geum hada 'wonder'," in the matrix verb phrase in Gyeongsang Korean. Using the same procedure as Yun (2022), 72 responses and response times for each stimulus were collected from 24 participants over the course of three trials. The stimuli were recorded readings of 40 speakers (20 male, 20 female). Context was provided to induce a matrix scope interpretation of the embedded wh-phrase in the target sentence. We sorted the 40 stimuli according to the number of matrix scope responses each received, and charted the response times for each stimulus. Although there was considerable overlap for the different types of wh-scope interpretations, there was a clear difference in categorical perception between the matrix and embedded scopes. The 24 participants also differed in their categorical perceptions. The results suggested that response time and wh-scope interpretation were not directly related and that two main weighted factors affected wh-scope interpretation: morpho-syntactic constraints and prosodic structural integrity. The weighting of each of these factors was inversely correlated and varied among subjects.
