본 연구는 시간자원의 중요성이 증가하는 현대사회에서 주부가 지각하는 시간압박 감이 점차 높아질것으로 예상되는 가운데 시간압박감이 소비자행동에 어떻게 작용하고 그로 인한 문제점은 무엇인지 밝혀보려는 의도에서 수행되었다. 서울시에 거주하는 주부 546명을 대상으로 시간압박지각정도를 측정하고 이를 바탕으로 소비자집단을 분류된 소비자 집단 사이에 인구.사회 경제적특성과 시간 절약형 내구제의 구매의사결정 과정의 차이가 있는지 분석하였다. 그 결과 시간 압박지각 정도에 따라 고.중.저의 세집단으로 구분되었는데 중간집단에 가장 많은 응답자가 포함되었고 높게 지각하는 집단에 가장 적은 응답자가 포함되었다. 그러나 기존의 연구와는 달리 취업주부의 18.7%가 시간압박을 낮게 지각하는 집단에, 그리고 전업주부의 6.8%가 시간압박을 높게 지각하는 집단에 분류되어 취업주부가 시간압박을 높게 지각하는 전형적인 소비자집단이 아닐수 있음을 발견하였다. 집단별 인구.사회경제적 특성과 시간절약형내구재의 구매의사결정과정의 차이도 부분적으로 밝혀졌으나, 예상과 달리 시간압박감을 높게 지각하는 집단의 시간절약형내구재의 소유와 사용이 오히려 낮게 나타났다.

This study examined the differences in facial emotion processing related to psychopathic traits. On the basis of the Psychopathic Personality Inventory-Revised (Lee & Park, 2008), students were divided into psychopathic trait (n=15) and control (n=15) groups. Participants performed two tasks consisted of negative(angry, fear, sad) and neutral faces. Event-related potentials(EPRs) were recorded when participants categorized gender in the implicit task and emotion in the explicit task. We analyzed the late positive potentials(LPP) amplitude to investigate differences in emotion processing between psychopathic trait group and control group. In the implicit task, there was no significant difference in both groups. However, there was a significant interaction between emotion and group at the frontocentral region in the explicit task. The psychopathic trait group showed greater LPP amplitudes for the neutral faces than for the negative faces, whereas the control group showed similar LPP amplitudes for the neutral and negative faces at the frontocentral site. These results might reflect the abnormalities in emotional processing in individuals with psychopathic traits.

In this paper, we analyzed the case of supporting the mathematical modeling activities through the group creativity in everyday class of 9th grade. The details are as follows. First, through the theoretical review, the meaning of group creativity according to sociocultural perspective and the sociocultural characteristics of mathematical modeling were confirmed. Second, we experimented in a classroom consisting of 5 groups of 4 students, and conducted a case study focusing on a well developed group of group creativity. The results are as follows. First, group creativity with various types of interaction and creativity synergy was observed at each stage of mathematical modeling. According to the stag e of mathematical modeling and the type of interaction, different creative synergy was developed. Second, the developed group creativity supported each step of mathematical modeling. According to the stage of mathematical modeling and the type of interaction, group creativity supported mathematical modeling activities in different directions.

This study analyzes the authorship of all articles published in four domestic LIS journals over a 20-year period from 2002 to 2021 to examine the current status of scholarly communication through Korean LIS journals and suggest future prospects. To achieve this purpose, the study analyzed the number of co-authors, the proportion of returning authors, the publishing preference index (PPI), the author group change trend, and the researcher attraction index (RAI). The analysis revealed the level of collaborative research in each journal, the degree of formation of related author groups by journal, the inflection point of author group changes, the characteristics of emerging researchers, and the degree of author sharing between journals. Overall, 2015 was found to be an inflection point where the author community of Korean LIS journals changed. The newer generation of researchers showed a slightly different behavior of publishing papers than the older generation, as they mainly conduct collaborative research. These quantitative results could be triangulated with the qualitative interview data of previous studies to further strengthen the development strategy of Korean LIS journals.

The purpose of this study was to examine whether the effect of feedback would mask the performance differences that would result from different incentive pay distribution. Five critical service behaviors were identified and measured daily at a gas station located in Seoul. Participants were 5 employees working at the gas station. Independent variables were the types of incentive distribution and feedback. After baseline (A), equally-distributed group incentive condition (B) was introduced, and individual incentive condition (C) was introduced in the next phase. Then, after the withdrawal condition (A'), equally-distributed group incentive with feedback condition (B') was introduced and finally, the individual incentive with feedback condition (C') was introduced. The results suggested that all employees showed higher work performance under individual incentive than equally-distributed group incentive system when feedback were not delivered. However, there was no difference in work performance between two incentive conditions in the phases in which feedback were delivered. These findings suggest that feedback can reduce performance differences between equally-distributed group incentives and individual incentives.

This study examined the effect of cognitive ability levels on skill acquisition and transfer as a function of training difficulty. Participants were classified into three groups based on the result of cognitive ability tests. They were trained with difficult or easy tasks and then transferred to novel difficult tasks. Results suggest that cognitive ability levels influenced training performance, though the effect of training difficulty on transfer performance varied with cognitive ability. The training difficulty was most effective for those who have the medium level of cognitive ability. These results were discussed with respect to individual differences and skill transfer performance.

This study was conducted to compare the learning styles and self-leadership between engineering college students with high and low team performance records. About 70% of students in high team performance group showed learning styles of converger and accommodator, whereas about 67% of students in low team performance group showed learning styles of accommodator and diverger. In regard to self-leadership, high team performance group showed higher level of self-leadership, especially self-observation, self-punishment, natural reward strategies, visualizing successful performance, self-talk, and evaluating beliefs and assumptions. It is recommended to provide the engineering students with the specialized training program to complement their learning styles and self-leadership strategies.

In this study, the effects of visual organization and cooperative learning in problem-solving strategy were investigated. Three classes (N=127) at a high school were assigned to SV (Strategy-Visual organization) group, SVC (Strategy-Visual organization-Cooperative learning) group, and control group. After instructions, students' multiple-choice problem-solving ability, strategy performing ability, anxiety about chemistry learning, perception of involvement, and motivation to learning science were examined. Although multiple-choice problem-solving ability was not different significantly, there was a significant main effect in strategy performing ability. The scores of the SV and SVC groups were significantly higher than those of the control group, especially in the subcategories of problem understanding and recalling related principles. In the tests of perception of involvement and motivation to learning science, the scores of the SV and SVC groups were also significantly higher than those of the control group. However, problem-solving strategy using visual organization could not alleviate anxiety about chemistry learning.

This study aims to estimate policy effects that appear heterogeneously within the beneficiary group by matching the beneficiary and non-beneficiary groups based on propensity score quartiles and analyzing the effect of policy benefits on sales growth. To achieve this, 239 SMEs that participated in R&D support program for the manufacturing of materials, components, and equipment in 2020 were selected as the beneficiary group. The propensity scores of these companies were calculated and divided into eight quartiles for matching between the non-beneficiary and beneficiary groups. Subsequently, double difference analysis was used to calculate the sales growth rate attributable to policy support. The study found that the largest policy effect was observed in the lowest quartile group, and companies with high patent application rates and 3-year sales growth rates experienced significant policy effects. These findings suggest that propensity score quartile-based analysis can be effectively utilized to refine the criteria for selecting beneficiary companies and the scope of industrial policy support.
