In this paper, we aimed to analysis EEG signals related to the relativity between musical stimuli and human brain activity for the arithmetical calculation and present the experimental results. We use two kinds of musical stimuli, one is a sedative tendency music and the other is a stimulative tendency music. The SMR wave and Mid-beta wave are analyzed because of the concentration. In our results, the sedative tendency music is not more interfere with human brain activity for the arithmetical calculations than the stimulative tendency music.

In this paper, we analyzed through the EEG signals how musical stimulus affects learning activities. Musical stimuli were divided into sedative and stimulative tendency music, preferred and non-preferred music, and the learning activity tasks were divided into mathematics tasks and memorization tasks. The signals measured in the EEG experiments were analyzed with the power spectrum of SMR waves known to be related to human concentration. Those spectra used for quantitative comparison in this paper. As a result the power of the EEG signals was observed to be greater than the case where music was given as a stimulus. Regardless of the type of task, the power of the EEG signals was observed to be greater in the case of sedative tendency than in the case of stimulative tendency, and the power of the EEG signals was observed to be greater in the case of favorite music than in the case of unfavorite music. From these results, it is estimated that if the musical stimulus exists, in the case of sedative tendency music, and in the case of favorite music, concentration can be increased than in the relative case.

In this paper, we measured and analyzed the EEG signals related to the relativity between musical stimuli and human concentration for memorization. In our experiments, the subjects carried out the tasks related to human memorization exposing to musical stimuli and the tasks are to memorize the english words. We used two kinds of musical stimuli, one is a sedative tendency music and the other is a stimulative tendency music. We presented the results that are analyzed as the EEG signals by frequency bands, respectively.

TIMSS-R 등 국제적 검사 결과로부터 알 수 있듯이 우리 학생들의 수학교과에 대한 정의적 영역의 성취도는 매우 낮은 실정이다. 진정한 의미의 수학적 힘은 인지적 영역과 함께 정의적 영역에 대한 의미 있는 학습을 통해서 길러진다는 사실을 생각할 때, 이는 우리 수학교육이 당면하고 있는 심각한 문제점이 아닐 수 없다. 본 논문에서는 이미 밝혀진 수학 기피요인들을 이용하여 학년이 올라감에 따라서 우리 학생들의 수학적 성향이 어떻게 변화하는지를 살펴보고 수학적 성향의 교육과 관련하여 몇 가지 제안을 하였다.

기존 사업에만 매진할 것인가, 아니면 새로운 미래에 도전할 것인가. 이 논제는 오늘날 많은 기업들이 떠안고 있는 고민임에 분명하다. 그런데 최근 기업들의 위험 기피 성향이 두드러지면서, 기업가정신의 실종과 무기력화를 우려하는 목소리가 높아지고 있다. 이에 기업가정신의 발현을 가로막는 잘못된 사회통념을 점검하고, 진정한 리더의 모습을 제안하고자 한다.

The aim of this study was to recognize guardians' desire and awareness on sedation, and to guide guardians' satisfaction and cooperation. Followings are the conclusion : 1. Information supply about conscious sedation were restrictive and insufficient. 2. Both first-visit guardians and guardians of sedated patients were interested in decrease of dental fear. 3. Both first-visit guardians and guardians of sedated patients were satisfied with psychological improvement better than behavior improvement. Therefore, decrease of patients'ear and anxiety was essential. 4. Both first-visit guardians and guardians of sedated patients didn't recognize accurate safety of conscious sedation.

이 연구는 MBTI 심리기능을 근거로 사용자 유형을 ST와 NF로 구분하고, 그룹별로 나눈 일상대화를 전사 후 분석하여 대화에서 나타나는 청자의 공감적 반응이 성향에 따라 차별화되는 점을 발견하고 이를 챗봇 대화 실험에 적용하여 분석결과의 유효성을 귀납적으로 증명하였다. 고성능의 초대규모 생성모델을 필두로 한 채팅 에어전트 구현이 보편화된 시점에서 진정 가치있는 대화 모델은 유창한 언어 구사 능력뿐만 아니라 사용자의 성향에 적합한 만족스러운 대화 경험을 제공할 수 있어야 함을 시사한다. 이 연구는 리얼월드의 대화 방식을 모방하여 챗봇 대화로 재현하였다는 점에서 실질적인 B2C 대화 서비스의 질적 향상에 기여도가 높을 것으로 기대된다.

This study quantitatively analyzed the speeches of the former 8 Presidents of the Republic of Korea. Unlike the previous studies, this study analyzed both the content word and the functional word related to the psychological phenomenon. In Study 1, six language style indicators such as clout, authenticity, presidentiality, cognitive complexity, femininity, and psychological health were developed. Also, as presidential speeches have been made recently, authenticity, presidentiality, psychological health tended to increase, but cognitive complexity tended to decrease. These tendencies were supported by linear trend analysis. The linguistic differences were distinct not only among individual presidents but also by groups based on the political orientation of the president. In the progressive presidential speech, more clout, cognitive complexity, femininity were observed. In contrast, more authenticity and presidentiality were observed in the conservative presidential speech. In Study 2, it was demonstrated whether the developed language style indicators show reliability in the most recent President's speeches. Finally, it was discussed that the relationship between language style indicators, fitness of the political tendency between the regime and the general public since 2000s, and the characteristics of femininity indicator.

수학의 세계에서 진정 우리가 배워야 할 것은 생각하는 수학적 힘의 양성과 현실에서 그것을 이용하여 예측력을 향상시키는 것이라고 생각한다. 수학적 힘을 현실세계에 적용, 분석할 수 있는 것 중 그 틀이 구조적이고 수학적 성향을 가지고 있는 제도에 관한 건은 가장 적합한 소재이다. 본 논문은 많은 제도 중 하나인 편입학제도를 수학에서 중요한 개념인 연속성을 이용하여 위상수학적으로 접근하여 살펴보고 그에 대한 문제점과 나아갈 방향을 제시하고자 한다.

This study was conducted to find out the psychosocial-demographic factors affecting the ambivalent sexism and attitudes toward homosexuality of school health teachers. The data were collected from December 1^st to 31^st, 2019 by administering a structured online questionnaire for 138 school health teachers in S city. The data were analyzed via SPSS/WIN (25.0) to run Kruskal-Wallis 𝑥² test, Mann-Whitney U test, Spearman's rank correlation, and Stepwise multiple regression. The results showed that the influential factors on the hostile sexism include authoritarian personality, age, extrinsic religious orientation, and education. Compared to this, the benevolent sexism had the influential factors of authoritarian personality, age, and education. The influential factors to the attitudes toward homosexuality found to include authoritarian personality, whether or not have a religion, and intrinsic/extrinsic religious orientation. School health teachers affect the educational experiences of students of their gender stereotyping and prejudice in the school environments. Therefore, it is needed to establish and provide training programs for school health teachers so that they can have reflections on their gender perspectives themselves, which may lead to true educational changes based on gender equality.
