This study used a Chatbot, a generative artificial intelligence (AI), to analyze the interaction between the Chatbot and students when exploring critical minerals from an epistemological aspect. The results, issues to be kept in mind in the teaching and learning process using AI were discussed in terms of the role of the teacher, the goals of education, and the characteristics of knowledge. For this study, we conducted a three-session science education program using a Chatbot for 19 high school students and analyzed the reports written by the students. As a result, in terms of form, the students' questions included search-type questions and non-search-type questions, and in terms of content, in addition to various questions asking about the characteristics of the target, there were also questions requiring a judgment by combining various data. In general, students had a questioning strategy that distinguished what they should aim for and what they should avoid. The Chatbot's answer had a certain form and consisted of three parts: an introduction, a body, and a conclusion. In particular, the conclusion included commentary or opinions with opinions on the content, and in this, value judgments and the nature of science were revealed. The interaction between the Chatbot and the student was clearly evident in the process in which the student organized questions in response to the Chatbot's answers. Depending on whether they were based on the answer, independent or derived questions appeared, and depending on the direction of comprehensiveness and specificity, superordinate, subordinate, or parallel questions appeared. Students also responded to the chatbot's answers with questions that included critical thinking skills. Based on these results, we discovered that there are inherent limitations between Chatbots and students, unlike general classes where teachers and students interact. In other words, there is 'limited interaction' and the teacher's role to complement this was discussed, and the goals of learning using AI and the characteristics of the knowledge they provide were also discussed.

The interaction of mastoparan B, a tetradecapeptide toxin found in the hornet Vespa basalis, with phospholipid bilayers was investigated. Synthetic mastoparan B and its analogs, obtained by substituting one hydrophilic amino acid (2-Lys, 4-Lys, 5-Ser, 8-Ser, 11-Lys, or 12-Lys) in mastoparan B with Ala, were studied. Mastoparan B and its analogs were synthesized by the solid-phase method. As shown by circular dichroism spectra, mastoparan B and its analogs adopted an unordered structure in buffer solution. All peptides took an α-helical structure, and the α-helical content of its analogs increased in the presence of neutral and acidic liposomes as compared to that of mastoparan B. In the calcein leakage experiment, we observed that mastoparan B interacted more weakly with lipid bilayers in neutral and acidic media than its analogs. Mastoparan B also showed slightly lower antimicrobial activity and hemolytic activity towards human erythrocytes than its analogs. These results indicate that the greater hydrophobicity of the amphiphilic α-helix of mastoparan B by replacement with alamine residues results in the increased biological activity and helical content.

In our time the parent's role is changing from sexually differentiated to androgynous pattern. Mother's interction with infant includes caring and father's interaction especially have play. Father and mother share the caring and play because they have complementary nature. Infants have a tendency to show more positive responses to their fathers than mothers in play situations. For that reason we can help the promotion of father's interaction with his infant through ascertaining patterns of father-infant play interaction. This study was to find out patterns of father-infant play interaction in order to improve the Interaction between father and infant. Data was video-taped from 6 fathers and infants who were healthy and first-timed and 7-11 weeks old in their houses. I used Father-Infant Play Interaction Scale that was applied to father instead of mother as a care-giver. The scale was checked up by experts in this field for content validity and the reliability was 0.95 in this study. The results were as follows : 1. Father's play behaviors were the patterns of responses about infant's cue. The mean score was 33.16(SD, 9.11), This means they come up to the standard level of responses about infant's cue. 2. Infant's play behaviors were the patterns of responses about father's cue. The mean score was 7.00(SD,3.10). This means they get the higher level of responses about father's cue. 3. The patterns of simultaneous responses occured together between father and infant. The mean score was 9.58 (SD, 3.96). This means they reach the standard level of simultaneous responses between father and infant. 4. The patterns of interactional behaviors occured interpersonally between father and infant. The mean score was 49.75(SD, 15.80). This means they interact on the standard level of play interaction. In view of the results father's play interaction seems to reveal an average level and play patterns are similar to mother's. In order to ascertain definitely patterns of father-infant play interaction we need further research which has more subjects and variables to have important effects.

The factors that affect the nurse-patient interaction were identified. Sixty-six nurses participated in the cross-sectional survey. Based upon the literature, the factors were classified into 4 categories : the patient, the nurse, the family caregiver, and the situational factors. The data were collected with the open-and closed-ended questionnaire developed by researchers. In the closed-ended questionnaire, the significant factors differentiating the best-liked from the least-liked caring situation were found in all factors except the nurse factors. None of the nurse factors was found to be significant. In patient factors, the physically attractive stereotype was found to affect patient-nurse interaction. As expected, family caregiver factors were found to affect the nurse-patient interaction. The content analysis was done to identify the specific factors affecting nurse-patient interaction. In both of the best-liked and the least-liked caring situations, the patient factors were the most contributing causes as likely as 68.51% and 66.45%, respectively. Some factors that nurses perceived as causes for the best-liked and the least-liked to care were presented. In conclusion, these results show that nurses are influenced by stereotypes in caring patients. So, some programs to increase awareness of the biases of nurses are included in in-service education. Also the incentives to encourage nurses are needed.

Objectives: The purpose of this study is to investigate the interaction and satisfaction of with web-based lectures. In addition, it seeks identify their correlations as well as the factors that influence satisfaction. Methods: The study subjects consisted of 139 college students taking up dental hygiene from Suncheon. ANOVA, correlation analysis, and regression analysis were used on the data collected. The Cronbach's alpha for interaction and satisfaction were 0.949 and 0.921, respectively. Results: The interaction recorded was moderate compared to face-to-face lectures. In particular, interaction between students was higher among 3rd grade students compared to those in the 1st grade (p=0.002). Satisfaction with the appropriateness of lecture content and duration was high, but relatively low in terms of the quality of the lecture and the desire to broaden its scope. In particular, satisfaction was higher among students in higher grade levels than their more junior counterparts (p<0.05). It was also found to be positively correlated with interaction (p<0.01). Their respective presence on the educational platform had the greatest impact on satisfaction (β=0.495, p<0.001). Conclusions: Increased interaction results in greater levels of satisfaction. Furthermore, an improvement in the quality of the lectures and the students' perception of them would enable lectures to be conducted more effectively in situations wherein face-to-face lectures cannot be done.

본 논문에서는 입체 영상 디스플레이 시스템 환경 하에서 다중의 사용자가 입체 영상 내의 사물과 상호작용이 가능한 입체 인터랙티브 콘텐츠 시스템 개발 방법을 제안한다. 상호작용을 위한 방법으로는 최근 대중적으로 많이 보급된 멀티터치 방식을 이용하여 사용자의 제스쳐 정보를 입체 영상 환경 하의 사물에 적용한다. 기존 멀티터치 방식은 디스플레이 표면과의 직접적 접촉을 통해 상호작용이 발생하나, 입체 영상의 경우 디스플레이 표면과 참여자 간의 적정 거리가 떨어져야 한다는 제약조건으로 기존 방법을 적용하기 어렵다. 이를 해결하기 위해 공간 상에 상호작용을 위한 비가시성 표면을 생성하고, 생성된 표면과 참여자의 신체와의 접촉을 상호작용의 이벤트로 간주한다. 또한 본 논문에서는 상호작용이 가능한 입체 영상 저작을 위해 게임 엔진 기반의 입체 영상 생성 및 편집 기법을 제시한다.
