Injection compression molding (ICM) is an advantageous processing method for producing thin and large polymeric parts in a robust manner. In the current study, we employed the ICM process for an energy-related application, i.e., thin and large polymeric battery case. A mold for manufacturing the battery case was fabricated using injection molding. The filling behavior of molten polymer in the mold cavity was investigated experimentally. To provide an in-depth understanding of the ICM process, ICM and normal injection molding processes were compared numerically. It was found that the ICM had a relatively low filling pressure, which resulted in reduced shrinkage and warpage of the final products. Effect of the parting line gap on the ICM characteristics, such as filling pressure, clamping force, filling time, volumetric shrinkage, and warpage, was analyzed via numerical simulation. The smaller gap in the ICM parting line led to the better dimensional stability in the finished product. The ICM sample using a 0.1 mm gap showed a 76% reduction in the dimensional deflection compared with the normal injection molded part.

Inhaled solvents such as toluene are of particular concern due to their abuse potential that is easily exposed to the environment. The inhalation of toluene causes various behavioral problems, but, the effect of short-term exposure of toluene on changes in emotional behaviors over time after exposure and the accompanying pathological characteristics have not been fully identified. Here, we evaluated the behavioral and neurochemical changes observed over time in mice that inhaled toluene. The mice were exposed to toluene for 30 min at a concentration of either 500 or 2,000 ppm. Toluene did not cause social or motor dysfunction in mice. However, increased anxiety-like behavior was detected in the short-term after exposure, and depression-like behavior appeared as delayed effects. The amount of striatal dopamine metabolites was significantly decreased by toluene, which continued to be seen for up to almost two weeks after inhalation. Additionally, an upregulation of serotonin 1A (5-HT_1A) receptor in the hippocampus and the substantia nigra, as well as reduced immunoreactivity of neurogenesis markers in the dentate gyrus, was observed in the mice after two weeks. These results suggest that toluene inhalation, even single exposure, mimics early anxiety-and delayed depression-like emotional disturbances, underpinned by pathological changes in the brain.

연구목적 - 최근 기업에서 마케팅이나 광고를 할 때 아트를 활용하여 기존의 명화나 아티스트들과 협업한 새로운 작품을 제품에 접목하거나, 마케팅에 활용하는 경우가 늘어나는 추세이다. 아트 콜라보레이션 제품을 새로운 자극으로 생각하고, 자극에 민감하게 반응하는 독특성 추구성향과 호기심이 많은 소비자일수록 아트 콜라보레이션 제품에 대한 호감도가 증가할 것으로 본다. 따라서 본 연구는 아트마케팅에 대해 전반적으로 살펴보고, 개인특성인 호기심과 독특성 추구성향이 아트 콜라보레이션 제품에 대한 소비자의 감정에 미치는 영향과 구매의도에 미치는 영향을 알아 보았다. 그리고 성별에 따라 개인특성과 소비자의 감정 사이에 미치는 영향은 차이가 있을 것이라 예측하고 성별의 조절효과를 살펴보았다. 연구결과 - 호기심은 긍정적 감정에 정의 영향을 미치며, 환기와 부정적 감정에는 영향을 미치지 않는 것으로 나타났다. 독특성 추구성향 중 창의적 선택은 긍정적 감정과 환기에 정의 영향을 미치며, 부정적 감정에 부의 영향을 미치는 것으로 나타났다. 독특성 추구성향 중 비대중적 선택은 긍정적 감정과 부정적 감정에는 영향이 없는 것으로 나타났으며, 환기에는 유의한 것으로 나타났다. 그리고 독특성 추구성향 중 유사성 회피는 소비자의 감정에 어떠한 영향도 미치지 않는 것으로 나타났다. 그리고 성별에 따른 차이를 살펴본 결과, 창의적 선택과 부정적 감정 사이와 비대중적 선택과 부정적 감정 사이에서만 남녀 간의 차이가 유의한 것으로 나타났다. 시사점 - 소비자의 호기심을 유발시킬 수 있는 새로운 디자인이나 전략을 시도하면 효과적일 것을 알 수 있으며, 독특성 욕구 중 자신의 정체성을 표현하고자 하는 욕구가 높은 사람이 아트 제품에 대하여 감정의 영향을 많이 받음을 알 수 있다. 따라서 지속적으로 예술가들과 콜라보레이션 활동을 통해 소비자의 감성을 자극하는 제품을 생산해야 할 것이다. 성별에 따른 큰 차이가 없으므로 남녀 구분없이 모두의 관심을 끌 수 있는 마케팅을 해도 무관하다는 것을 알 수 있다.

This study analyzed the relationship between self-directedness of science-gifted elementary students and their expression of scientific creativity in science-gifted class. A science-gifted program on the topic of Hydraulic Machine was implemented to 34 fifth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea for four weeks. The self-directedness of the gifted students was divided into three types of 'General, Scientific, and Topic-Related Self-Directedness'. The products of the students' activities were assessed by using a scientific creativity assessment formula. Qualitative research, such as analysis of observations and interviews, was also conducted in order to identify characteristics that were not apparently revealed by quantitative data. The main results of this study are as follows: First, science-gifted elementary students' general self-directedness and their scientific creativity were significantly correlated (r=.373). Second, the students' scientific self-directedness and scientific creativity did not have a significant correlation (r=.294). Third, there was a positive correlation between the students' topic-related self-directedness and their expression of scientific creativity. Their self-rated scores (r=.420) for the topic-related self-directedness and the number of activity types associated with the topic had a positive correlation (r=.350). Fourth, the students were categorized into four groups according to the levels of their self-directedness and scientific creativity, and the result showed that Type HH (high self-directedness and high scientific creativity) was the most common type (15 students, 38.5%), followed by Type LL (low self-directedness and low scientific creativity) (11 students, 28.2%). Eight (20.5%) and five students (12.8 %) belonged to Type LH (low self-directedness and high scientific creativity) and Type HL (high self-directedness and low scientific creativity) respectively. Fifth, the classroom observation of the students in groups revealed that groups with more number of Type HH demonstrated better cooperation and performance. Sixth, the analysis results of the observation were almost matched to the results of the self-directedness and scientific creativity tests. The students with higher self-directedness demonstrated active class participation and good cooperative skills. The students with higher scientific creativity had a tendency to generate creative ideas more frequently in given situations. Seventh, dynamic activities were perceived as enjoyable and exciting by 76.9% of the students, but static activities that require creativity were regarded as interesting only by 23.1% of the students. Among the students who were satisfied with both the creative and static activities, Type HH accounted for the largest proportion (55.6%). In conclusion, factors such as students' interests, initiatives, and attitudes displayed through voluntary participations originated from their own daily life can predict the degree of scientific creativity associated with the topic. Also, when students were categorized into four types according to the level of self-directedness and scientific creativity, there was a tendency of active behavior in class, cooperative skill, and activity satisfaction. This suggested that we should consider self-directedness and scientific creativity in selecting the gifted, grouping them in class, and designing and executing programs for science-gifted elementary students.
