The purpose of this study was to analyze qualitatively perception on creativity and character education of teachers who participated in winter training and workshop which the Southeast Regional Center for Creativity and Character Education arranged. The results are as follows. Firstly, it was shown that teachers perceived close corelation between creativity and character and competency necessary for students who will make a living for future society. Secondary, Teachers perceived that creativity and character education will benefit students in their cognitive, emotive, and affective aspects. Lastly, teachers thought that an administrative assistant and financial help such as securing classroom had to be supported so that they were able to freely conduct creativity and character education and teaching materials provided by the Regional Center for Creativity and Character Center were helpful in establishing a whole foundation when they started to conduct creativity and character education.

Working memory (WM), which plays a vital role in daily activities, is a memory system that temporarily stores and processes information when people are engaged in complex cognitive activities. The influence of music on WM has been widely studied. In this work, we conducted a series of n-back memory experiments with different task difficulties and multiple trials on 14 subjects under the condition of no music and Alpha wave leading music. The analysis of behavioral data show that the change of music condition has significant effect on the accuracy and time of memory reaction (p<0.01), both of which are improved after the stimulation of Alpha wave music. Behavioral results also suggest that short-term training has no significant impact on working memory. In the further analysis of electrophysiology (EEG) data recorded in the experiment, auto-regressive (AR) model is employed to extract features, after which an average classification accuracy of 82.9% is achieved with support vector machine (SVM) classifier in distinguishing between before and after WM enhancement. The above findings indicate that Alpha wave leading music can improve WM, and the combination of AR model and SVM classifier is effective in detecting the brain activity changes resulting from music stimulation.

Objective: This study aims to examine the impact of young children's playfulness and self-esteem on their creative personality. Methods: The sample consisted of 332 four- and five-year-old children enrolled in kindergartens and daycare centers in Incheon. Teacher-report measures of playfulness, self-esteem, and creative personality scales were used for data collection instruments. The collected data were analyzed using t-test, analysis of variance, correlation analysis, and multiple regression analysis. Results: Firstly, significant differences were found in all variables based on children's gender, while age and birth order did not show statistically significant differences. Secondly, young children's playfulness and self-esteem were found to have a positive impact on their creative personality. Specifically, among the sub-variables, cognitive spontaneity and humor in playfulness, along with competency in self-esteem, showed relatively higher levels of impact on young children's creative personality. Conclusion/Implications: The study findings emphasize the necessity of comprehensive support systems that foster playfulness and self-esteem to enhance young children's creative personality. This includes providing proper teacher training and a range of instructional materials, along with parental education.

Double-front construction machinery, which was designed for complicated tasks, requires intelligent systems that can provide the quantitative work analysis needed to determine effective work procedures and that can provide operational and cognitive support for operators. Construction work environments are extremely complicated, however, and this makes state identification difficult. We therefore defined primitive static states (PSS) that are determined using on-off data for the lever inputs and manipulator loads for each part of the grapple and front and that are completely independent of the various environmental conditions and operator skill levels. To confirm the usefulness of PSS, we performed experiments with a demolition task by using our virtual reality simulator. We confirmed that PSS could robustly and accurately identify the work states and that untrained skills could be easily inferred from the PSS-based work analysis. We also confirmed in skill-training experiments that advice information using PSS-based skill analysis greatly improved work performance. We thus confirmed that PSS can adequately identify work states and are useful for work analysis and skill improvement.

Objectives: This study aimed to explore the short-term effects of bilateral masticatory training using an intraoral device on memory and concentration, which is an advanced form of Gochi, compared to the unilateral form with gum. Methods: Thirty young healthy participants (age, 16-30 years) were screened and randomly assigned to one of two sequences in a crossover design. The participants assigned to sequence A (n=15) performed bilateral mastication using an intraoral device with a total of 300 taps, followed by unilateral mastication using gum with the same number of repetitions and frequency, separated by a 7-day washout period. A reverse order was used for sequence B. The primary and secondary outcomes were the digit span test result and the symbol digit modality test and the word list recall results, respectively, which were conducted before and after each intervention. Results: Symbol digit modality test scores increased by 12.03±8.33 with bilateral mastication, which was significantly higher than that obtained with chewing gum (5.17 points;95% confidence interval: 0.99, 9.34; p<0.05). Changes in the digit span test and word list recall scores were not significantly different between the two groups. In the digit span test forward, symbol digit modality test, and word list recall test, bilateral mastication was not inferior to unilateral mastication in improving memory and concentration. Conclusions: Bilateral masticatory exercises using an intraoral device are not inferior to unilateral mastication with gum for improving memory in healthy young individuals. Further research is needed to determine the efficacy of bilateral masticatory training on cognitive function.

본 연구의 목적은 PS-2 (N141I) 알츠하이머 형질전환 모델 생쥐를 대상으로 트레드밀 운동이 뇌의 세포질과 미토콘드리아의 $A{\beta}$-42, cytochrome c, SOD-1, 2 and Sirt-3 단백질 발현에 미치는 효과를 알아보는데 있다. 우선 알츠하이머 형질전환 생쥐를 Non-Tg-sedentary (n=5), Non-Tg-treadmill exercise (n=5) 집단과 Tg-sedentary (n=5), Tg-treadmill exercise (n=5) 집단으로 구분하고 트레드밀 운동을 통한 신경보호 효과를 검증하기 위해 Tg와 Non-Tg집단에 12주간 트레드밀 운동을 수행한 후 인지능력을 살펴보고 뇌의 세포질과 미토콘드리아의 $A{\beta}$-42, cytochrome c, anti-oxidant enzymes (SOD-1, SOD-2)와 Sirt-3 단백질을 분석하였다. 먼저 트레드밀운동은 Tg 집단에서 인지능력의 개선을 나타냈으며 미토콘드리아의 $A{\beta}$-42와 세포질의 cytochrome c 단백질의 감소와 항산화 효소인 SOD-1, SOD-2를 유의하게 증가시켰다. 게다가 트레드밀 운동은 모든 집단에서 Sirt-3 단백질의 발현을 증가시켰다. 따라서 트레드밀 운동은 인지능력의 향상과 세포 내 스트레스를 유발하는 $A{\beta}$-42를 억제시켜 알츠하이머 질환을 개선시킬 수 있는 효과적인 방법이라고 생각된다.

조성음악의 경우는 음악적 음들의 상대적 중요성의 위계를 기초로 음들을 조직화하는 원리를 채택하고 있다. 해당 음악에 익숙한 청자들은 이런 원리에 대한 공식적 훈련을 받지 않아도 이와 일치하는 내적 지식. 즉 조성 도식(tonal schema)을 내재화하고 있다. 본 연구는 서양 음악의 조성적 음 조직화 원리에는 친숙하지만 한국 전통 음악, 즉 국악에는 친숙하지 않은 서양 음악 전문가는 국악 음들의 조성적 측면을 어떻게 해석할지 알아보고자 하였다. 타 음악 문화에 대해 이루어진 선행 연구들에서는 실험 자극 내 음들의 발생 빈도, 지속시간 등의 피상적 정보가 비친숙한 음악의 조성 도식을 추출해내는 단서로 사용될 수 있는 것으로 나타났다. 본 연구에서는 이런 가능성을 차단하기 위해 피상적 정보를 통제한 뒤 이 경우 서양 음악 전문가는 국악 음을 듣고 자신에게 친숙한 서양 음악의 조성 도식의 틀을 적용하여 음악적 관계를 해석한 것으로 나타났다. 또한 서양 음악 전문가가 국악 음을 서양 음악의 틀로 해석하여 국악의 조성 도식과 일치하지 않는 판단을 보이기는 하지만, 국악과 서양 음악 모두에 대해 초보 수준의 경험만 가지는 일반인보다는 국악 조성 도식에 유사한 해석을 보임으로써 국악과 서양 음각같이 한 스타일의 음악에 대한 경험은 다른 스타일의 음악을 보다 쉽고 적절하게 해석하는 것을 촉진하는 것으로 보인다.
