  • Amazon Go is a cashierless convenience store concept, which is seen as a disruption in the grocery retail segment. Although Amazon Go has the ability to disrupt the retail segment, there are speculations on how Amazon Go will be perceived by users. Existing studies have not utilized user-generated content to understand the factors that affect customer behaviour in case of Amazon Go. Additionally, in case of phygital retail, studies have not attempted at understanding the effect of emotions and gratifications on user behaviour. To address the gap of exploring user perspectives based on their experience, we have examined the impact of gratifications and emotions on the acceptance of phygital retail using user-generated-content. A mixed-method approach has been utilized using only user-generated content. Utilizing topic-modelling based content analysis and emotion analysis on 30 articles related to Amazon Go, we found themes like, convenience, technology, experience, personalization, enjoyment and emotions like, bad, good, annoyance, success. In the empirical analysis, we have utilized 522 reviews about Amazon Go from the cognition and emotion theory stance, and found that hedonic gratifications have a positive impact on challenge emotions. We also found a significant impact of emotions on customer's favourite behaviour.

  • During the post-pandemic period, the interest in foreign language learning surged, leading to increased usage of language-learning apps. With the rising demand for these apps, analyzing app reviews becomes essential, as they provide valuable insights into user experiences and suggestions for improvement. This research focuses on extracting insights into users' opinions, sentiments, and overall satisfaction from reviews of HelloTalk, one of the most renowned language-learning apps. We employed topic modeling and emotion analysis approaches to analyze reviews collected from the Google Play Store. Several experiments were conducted to evaluate the performance of sentiment classification models with different settings. In addition, we identified dominant emotions and topics within the app reviews using feature importance analysis. The experimental results show that the Random Forest model with topics and emotions outperforms other approaches in accuracy, recall, and F1 score. The findings reveal that topics emphasizing language learning and community interactions, as well as the use of language learning tools and the learning experience, are prominent. Moreover, the emotions of 'admiration' and 'annoyance' emerge as significant factors across all models. This research highlights that incorporating emotion scores into the model and utilizing a broader range of emotion labels enhances model performance.

  • This paper describes a technique for human sensibility evaluation using EEGs of 4 emotions. The proposed method uses the linear predictor coefficients as EEG feature parameters and a neural network as sensibility pattern classifier. For subject independent system, multiple templates are stored and the most similar template can be selected. EEG signals corresponding to 4 emotions such as relaxation, joy, sadness and anger are collected from 5 armature performers. The states of relaxation and joy are considered as positive sensibility and those of sadness and anger as negative. The classification performance suing the proposed method is about 72.6%. This may be promising performance in the human sensibility evaluation.

  • 이 연구는 중학교 과학 수업에서 학생주도평가가 성취정서와 과학개념이해에 미치는 영향에 대해 알아보는 것을 목적으로 하였다. 이를 위해 중소도시 소재 중학교 3학년 7학급 중 실험집단으로 선정된 4개 학급은 학생주도평가를 실시하고, 비교 집단(3개 학급)은 교사주도평가를 실시하였다. 학생주도평가는 학습자가 주도적으로 학습 목표 설정과 평가 기준을 개발하여 자기평가와 동료평가를 실시하는 4단계로 구성하였고, 개발한 7개 평가 활동을 수행하였다. 연구 결과, 학생주도평가는 긍정적 성취정서를 향상시키고, 부정적 성취정서를 완화시키는데 효과를 보였으며 중학생의 과학개념이해를 향상시켰다. 학생들은 학습목표 설정에 주도적으로 참여하고, 평가 기준을 개발하여 자기평가와 동료평가를 반복적으로 수행하며 자신의 도달 정도를 파악하고, 학습 과정에서 부족한 점을 보완하는 반복적인 반성적 사고를 거친다. 따라서 학생주도평가는 학습에 대한 책임감을 향상시키고 지속적으로 과학개념이해 정도를 점검할 수 있도록 하여 과학개념이해를 높이는 도구로써 활용될 수 있다.

  • Objectives: The study purpose was to test the validity and reliability of the core emotional assessment questionnaire based on the seven emotions. Methods: Survey data were from 651 individuals and contained 141 items determined from a previous pilot study. Among the participants, 241 were retested. First, following analysis of the internal consistency reliability of the 141 items, we deleted items with Cronbach-$\alpha$ coefficient below 0.5. We then selected 100 final items after the first factor analysis. Second, the final 100 items were evaluated by internal consistency reliability, test-retest reliability, factor analysis, and correlational analysis. Results: Cronbach-$\alpha$ coefficient for the final 100 items were 0.866~0.956 and the test-retest reliability were above 0.70. The 100 items categorized into 7 factors explained 53.8% of the total variance. Analyzing the correlation of each chiljeong, we had a high positive correlation above 0.70 between sa and bi, bi and u, gong and kyeong. Conclusions: The final 100 items used for the core emotional assessment questionnaire based on the seven emotions showed satisfactory reliability and validity. Thus, it may be an appropriate instrument for measuring Chiljeong in the general population.

  • Objectives: Chiljeong means the basic emotions containing joy, anger, anxiety, depression, fear and fright in Korean traditional medicine. Chiljeong was considered as a cause diseases or syndrome. The pathology of Chiljeong described the action of the gi and the principle of eumyangohaeng. When we treat the psychiatric symptoms in Korean traditional medicine, we need to understand the pathologic mechanism of Chiljeong. Methods: We extract the sentences regarding Chiljeong, Oji, Chilgi and Gugi along with the related words in Donguibogam. We analyze the selected sentences and classify the pathologic mechanism according to the general and seven emotions. Results: We found that several parts were related to Chiljeong, except the Sinmun, including the psychiatric symptoms in Donguibogam. Conclusions: The most frequently mentioned affected areas of basic Jangbu are Sim and Gan. The pathologic mechanism of general emotion was categorized by sentences into 4 groups, Giul, Dameum, Hwa and Heo.

  • 경판30장본<춘향전>과 연극<성춘향>을 기존의 관습적 분석과 텍스트를 벗어나 새로운 시각으로 비교 분석하여 서사구조, 연극공연에서 나타난 춘향의 행동, 태도, 사랑에 나타난 성향 등을 비교 분석하여 경판30 장본<춘향전>의 춘향과 연극<성춘향>의 춘향의 시대적 변화에 따른 인물 변모와 정서를 비교함으로써 고전소설이 가지고 있는 인물에 현시대의 정서를 가진 인물을 부합함으로써, 같은 텍스트와 같은 배경이지만 현재성이 다른 인물이 등장함으로써 현대 시대의 부조리함, 여성차별, 등을 풍자함으로써 메시지를 직설적으로 관객에게 전달하고 있다. 또한, 서사적 사건 비교 분석 결과에 나타난 경판30장본<춘향전>에서 정절을 지키며 변 사또의 횡포에 저항하는 열녀 춘향이라는 관습적인 주제 관념에서 벗어나 평범한 서민의 삶 속에서 남녀차별, 신분갈등, 부조리한 사회라는 상황 속에서도 자신의 신념을 갖고 지키는 춘향을 연극이라는 특수성을 결부시켜 '페미니시트적 자의식과 신념을 지키는 춘향'이라는 새로운 주제의식으로 재해석할 수 있다.

  • In this paper, we propose an emotion recognition method using the facial images and speech signals. Six basic emotions including happiness, sadness, anger, surprise, fear and dislike are investigated. Facia] expression recognition is performed by using the multi-resolution analysis based on the discrete wavelet. Here, we obtain the feature vectors through the ICA(Independent Component Analysis). On the other hand, the emotion recognition from the speech signal method has a structure of performing the recognition algorithm independently for each wavelet subband and the final recognition is obtained from the multi-decision making scheme. After merging the facial and speech emotion recognition results, we obtained better performance than previous ones.

  • This study examines a model which simultaneously contains two paths between waiting line and purchase intention: one tested the positive effect of waiting line through consumers' perceived quality, whereas another one go through consumers' emotional state to test the negative effect of waiting line on purchase intention. To further understand perceived quality, the study divided perceived quality into perceived product quality and perceived service quality. The study used restaurants in the experiment. Results indicated that although long waits in line will directly increase both consumers' product quality perception and negative emotions, the total indirect effects on purchase intention are still significantly positive. For consumers' perceived service quality, long waiting situations have no such effect on it. Significant results from a moderation analysis also shown that consumers in low-level knowledge settings are more influenced by waiting lines than those in high-level knowledge settings when they make the product's quality-related judgment. However, the level of consumer knowledge does not moderate the relationship between waiting lines and service quality.
