  • 본 연구의 목적은 판의 경계에 대한 그리기와 면담의 결과를 바탕으로 정신모형의 유형별 분석 준거를 도출하고 이를 근거로 고등학생들의 정신모형을 밝히는데 있다. 이를 위하여 고등학교 2학년 학생을 대상으로 충돌형, 섭입형, 발산형 판의 경계에 대한 그리기 과제와 개별 면담을 병행하여 실시하고 그 결과를 정성적으로 분석하였다. 본 연구의 결과, 판의 경계에 대한 고등학생들의 정신모형의 유형은 소박한 모형(naive model), 불안정 모형(unstable model), 인과적 모형(causal model), 개념적 모형(conceptual model)의 4가지로 분류되었다. 이러한 정신모형에 대한 분석 준거는 판과 맨틀을 구분하는지, 판과 하부 맨틀의 이동을 파악하는지, 판의 경계 지형의 특징을 인식하는지, 맨틀의 대류와 지형의 특징을 관련짓고 있는지 등의 요인이다. 판의 경계에 대한 '소박한 모형'과 '불안정 모형'을 지닌 학생들은 맨틀의 대류와 지형의 생성원인을 관련짓지 못한 반면, '인과적 모형'과 개념적 모형'을 지닌 학생들은 판의 경계에서 맨틀 대류와 지형의 생성과의 인과 관계를 인식하고 있었다. 정신모형 유형에 따라 꼭꼭 획득의 방법에 관한 학생들의 믿음을 조사한 결과, 소박한 모형과 불안정 모형을 지닌 학생들은 외부적인 권위에 의존하는 경향을 나타내었다.

  • The primary focus of the study assesses how individual spouses' and their partners' marital adjustment influence their own and their mental health. The study also examines whether this influence was mediated by the relationship with their adult-children. Data were collected from 271 dyads of elderly couples by using a self-report questionnaire. Marital adjustment was measured in terms of intimacy and comparison level of marriage. Mental health was measured in terms of depressive mood, anxiety, and somatization. The Actor-Partner Interdependence Model (APIM) analysis revealed that marital adjustment was positively associated with one's own mental health and with one's own relationship with their adult-children, but not with their partner's. On the other hand, the relationship with adult-children was positively associated with one's own and with their partner's mental health. Furthermore, analysis of the mediating model using APIM indicated that marital adjustment through one's own adult-children relationship had direct and indirect effects on one's own mental health. It is interesting to note that the wives' mental health were directly influenced by their partners' relationship with adult-children. However, the effect of the husbands' mental health was not significant. These findings highlight dyadic interdependence among spouses' perceptions of marital and adult-children relationship with their mental health. The results suggest implications for educators and clinicians working with elderly couples to improve their psychological and relational health.

  • The purpose of this study was to examine the effect of interactivity on consumers' mental imagery, attitude toward a product, confidence in evaluation and purchase intention. The proposed model was examined by conducting an experiment using mock apparel websites. A total of 1,009 female college students enrolled at a major midwestern university in the USA participated in the experiment. A structural equation model was used to test the model. The results of the study indicate that interactivity positively influenced mental imagery, attitudes toward a product imagery, and confidence in evaluation. The structural equation model also revealed that mental imagery positively influenced attitude toward a product and confidence in evaluation. Finally, the results show that attitude toward a product and confidence in judgment positively affected purchase intention. The study provides valuable theoretical perspectives which aide in the understanding of the effect of interactivity on consumers' cognitive and behavioral responses, and helps retailers develop effective marketing strategies.

  • Attention has been focused recently on the concept of shared cognition which encompasses the notion that effective team members hold knowledge that is overlapping and complementary with teammates. This shared cognition is expected to improve team effectiveness. In contrast to the continued efforts in developing theoretical approach of shared cognition, empirical studies are meager. Thus, we conducted an empirical study to investigate the role of shared cognition on team effectiveness. This study classifies shared cognition into two types, team mental model and transactive memory system, by shared meaning. A total of 121 new product development teams in the IT industry were surveyed for the data collection. The results of analysis can be summarized as follows: first, team mental model has a positive influence on team performance, team innovative behavior and team learning effect. And the relation with team mental model and team performance is moderated by the similarity of knowledge structure among the expert. Second, transactive memory system has a positive influence on team performance, team innovative behavior and team learning effect.

  • This study investigated undergraduate students' perceptions and mental models of the environment. A total of 192 students were sampled from a university of Gyoungbuk area. The environmental task was administrated to students drew a picture of an environment and explained their drawing. The results are as follows: First, a majority of undergraduate students perceived an environment from a comfortable environment. Second, five mental models emerged from a content analysis of students' responses about environmental drawing. Third, the dominant model was mental model 4, the environment as a place where animals, plants, and humans live. This means that the majority of students perceived a 'relation' rather than 'objects' views of the environment. Therefore, undergraduate students' conceptualizations about environment depends on a view or mental models of the environment which places humans in a sustaining relationship with the environment and its natural resources. The implications of these findings for environmental education are discussed.

  • Over seven years, BTS have organically embedded consistent mental health messaging and modelling of various mental health modalities, representing innovation within mental health discourse, within and outside the pop and K-pop culture and fandom. Their personal and artistic journeys have resulted in songs, imagery, and relationship dynamics within the group and within and between their fans ARMY, that organically model behaviours associated with mental health therapeutic modalities and normalize the discussion of mental health and well-being. This practice is vitally important in the effort to end stigma and encourage mental health well-being and recovery. BTS's authenticity establishes empathy with their audience ARMY and increases their ability to deliver these messages effectively. This includes fostering the creation of a peer support community within the group that extends to their fanbase ARMY, and from which fan-created mental health programs have emerged. BTS's innovation will be explored by examining content creation throughout their career, illustrating their consistent and organic messaging, culminating in overt and conscious mental health content in their latest album BE, which was released three weeks after the initial paper was presented, and provides proof of concept.

  • Objectives : These days assaults and other natural and human disasters are increasing. But oriental medical treatment researches in Korea are limited in car accident PTSD patients only. Our object is to explore an oriental medical intervention model for the evidence-based approach to PTSD after diverse trauma including disasters. Methods : Domestic papers for Korean researches are obtained from oriental medical related journals by internet searching. International materials are obtained from PubMed searching and a publication from Department of Veterans' Affairs. After assorting searched articles into RCTs and non-RCTs, we analyzed the articles according to the elapsed time from trauma. Results : We confirmed that acupuncture, CBT, and PMR were effective in acute stage after traumatic event. And EMDR, EFT, and relaxation therapy were effective in chronic stage after traumatic event. Building on the findings, we proposed a model of oriental medicine for Disaster Mental Health. Conclusions : Analyzing previous researches about oriental medicine on PTSD, several interventions were confirmed the effectiveness on specific treatment stage. We could find the possibility of Oriental Medicine as a Disaster Mental Heath and proposed a model of Oriental medicine for Disaster Mental Health.

  • The purpose of this study is to analyze the relationship between the mental model and the depictive gestures observed in the explanations of elementary school students about the reason why seasons change. As a result of analysis in gestures of each mental model, mental model was remembered as "motion" in case of CM-type, and showed more "Exphoric" gestures that expressed gesture as a language. CF type is remembered in "writings or pictures," and metaphoric gestures were used when explaining some alternative concepts. CF-UM type explained with language in detail, and showed a number of gestures with "Lexical." Analyzing depictive gestures, even with sub-categories such as rotation, revolution and meridian altitude, etc., a great many types of gestures were expressed such as indicating with fingers, palms, arms, ball-point pens, and fists, etc., or drawing, spinning and indicating them. We could check up concept understandings of the students through this. In addition, as we analyzed inconsistencies among external representations such as verbal language and gesture, writing and gesture, and picture and gesture, we realized that gestures can help understanding mental models of the students, and sometimes, we could know that information that cannot be shown by linguistic explanations or pictures was expressed in gestures. Additionally, we looked into two research participants that showed conspicuous differences. One participant seemed to be wrong as he used his own expressions, but he expressed with gestures precisely, while the other participant seemed to be accurate, but when he analyzed gestures, he had whimsical concepts.
