The Law of the Heart, which appears in the chapter "B. The Actualization of Rational Self-consciousness Through its own Activity" in Hegel's Phenomenology of Spirit represents that the self-certainty of the reason may be the another face of the Madness. The Reason's indubitable certainty is the testimony of the truth for Descartes, and it also plays a role as the moral maxim of the conscience for Kant. But this subjective certainty unavoidably leads to the Madness of self-conceit, which unifies the consciousness and the reality ignoring the difference between them. The typical attitude appearing in the reformer like Don Quixote and also romantic idealists reveals the fact that modern reason and the psychosis can be both faces of one and the same coin. The Mirror Stage, the Imaginary, and the Formula of the Desire in Lacan's Theory shows that the Image of completeness is the result of Mis-understanding. Even if the Mirror stage is necessary for the Formation of the subject, at the same time it should also lead to the next stage, i.e., the Symbolic Order. It is considered as the realm of the Otherness, which refers to the realm of language or that of law. If the Ego can't go through the symbolic castration acted on by the Name of the Father, he will be remained in the prison of the Imaginary. The Madness also shows the similar process. For Hegel the Discipline of the Labor or the Death as absolute Otherness that inevitably delays the Desire plays the same role as the name of Father. It may be the experience of Separation or that of Sublation of the individual towards the universal, which is equivalent to the experience of Symbolic castration in Lacan. Furthermore there may be the difference between Hegel and Lacan as the following; while in Hegel the experience of Separation is founded on the spontaneity of the Spirit, for Lacan it is to be compelled and structured by the absolute Other.

"이성적이며 이상적인 합리적 인간"을 가정하는 기존 경제학의 이론이 항상 실제 상황과 일치하지는 않는 것으로 알려져 있다. 이의 대안으로 나온 행동경제학은, 인간의 경제적 의사결정에 심리, 인지, 감정, 사회문화적 배경 등이 영향을 미친다고 본다. 본 연구에서는 행동경제학에 의거하여, 개인의 감정과 경험이 경제적 의사결정에 영향을 미치는지 여부를 빅데이터 모델을 활용하여 분석하였다. SNS 여론으로는 Reddit, 주가지수로는 S&P 500 을 선정하였다. 수집한 텍스트 데이터를 전처리와 감정분석을 통해 독립변수 값으로 사용했고, 주가지수 등락의 방향성을 종속변수로 사용하여 로지스틱 모형을 구성했다. 모델을 활용하여 분석한 결과 Public sentiment 와 Market sentiment 간 양의 상관관계를 확인할 수 있었다. 또한, lag 를 설정하는 모델이 정확도가 더욱 높음을 확인해, 기존 경제학의 EMH 와 대립되는 바를 확인할 수 있었다. 하지만 최적의 lag 산정을 위해, 더 광범위한 데이터를 바탕으로 한 후속연구가 필요하다.

This study examined the reasoning of gifted elementary science students in a socioscientific issues (SSI) classroom discussion on COVID-19-related trash disposal challenges. This study aimed to understand the characteristics of evidence use and decision-making difficulties in each type of SSI-related reasoning. To this end, the transcripts of 17 gifted students of elementary science discussing SSIs in a classroom were analyzed within the framework of informal reasoning. The analysis framework was categorized into three types according to the primary influence involved in reasoning: rational, emotional, and intuitive. The analysis showed that students exhibited four categories of evidence use in SSI reasoning. First, in the rational reasoning category, students deemed and recorded scientific knowledge, numbers, and statistics as objective evidence. However, students who experienced difficulty in investigating such scientific data were less likely to have factored them in subsequent decisions. Second, in the emotional reasoning category, students' solutions varied considerably depending on the perspective they empathized with and reasoned from. Differences in their views led to conflicting perspectives on SSIs and consequent disagreement. Third, in the intuitive reasoning category, students disagreed with the opinions of their peers but did not explain their positions precisely. Intuitive reasoning also created challenges as students avoided problem-solving in the discussion and did not critically examine their opinions. Fourth, a mixed category of reasoning emerged: intuition combined with rationality or emotion. When combined with emotion, intuitive reasoning was characterized by deep empathy arising from personal experience, and when combined with rationality, the result was only an impulsive reaction. These findings indicate that research on student understanding and faculty knowledge of SSIs discussed in classrooms should consider the difficulties in informal reasoning and decision-making.

The purpose of this study was to understand the factors with consumers' fashion experiential store experiences and investigate the effect on flow and brand attitude. The study also aimed to investigate whether gender moderated the relationship between consumers' fashion experiential store experiences and flow. An online survey of consumers in their 20s and 40s was conducted. The SPSS 27.0 program was used to perform frequency, factor, and reliability analysis. The structural equation model was analyzed using the SMART-PLS program. The structural model analysis confirmed that consumers' rational, physical, and relational experiences in fashion brand experiential stores strongly influenced flow and found that relational experience had the strongest influence on flow. The influence of rational, physical, and relational experiences and flow on brand attitude was confirmed, where flow had the strongest effect on brand attitude. The examination of the moderating effect of gender on the relationship between consumers' fashion experiential store experiences and flow found that the effect in men was significant for flow and brand attitude through rational experience and that the effect in women was significant for flow and brand attitude through relational experience. These results provide academic implications, and by strengthening consumer flow, we intend to propose the establishment of a marketing strategy and opportunity plan that can elicit a positive brand attitude.

The purpose of this study is to examine diverse factors influencing the adoption of IPTV services and relationships among them. To achieve the purpose, this study modified and applied the established theory of the Extended Technology Acceptance Model(ETAM) incorporating socio-cultural factor, flow experience and perceived behavioral control as related constructs. The suggested model was empirically tested through the structural equation modeling approach. The results are as follows: First, the socio-cultural factor and the perceived behavioral control have significant direct influences on the adoption of IPTV services. Second, the flow experience does not have a significant indirect influence mediated by the attitude toward IPTV services. Third, the socio-cultural factor has the significant relationships with the perceived usefulness and the perceived ease of use. Finally, the flow experience was influenced by the perceived usefulness and the perceived ease of use.

Gameplay exists not only in game activities, but also in other art forms. An animated film with strong gameplay whose gameplay narrative follows the presupposition principle, achieved through unimaginable sound effects, exaggerated visual styling, hypothetical time and space concepts, fictional storylines and character performances. The strength or the presence or absence of gameplay in animated films is reflected in the grasp and use of these gameplay elements in the process of animated film narratives. The gameplay narrative of animated films fully utilizes the characteristics of gameplay thinking. In the process of scriptwriting and narrative, it combines entertainment, action, adventure, competition and other elements to fully reflect the characteristics of "gameplay". Gameplay narratives often use the strategies of reverse setting, repetition and interaction, and rules and challenges setting, which not only enhances the fun of animated film narratives, but also attracts the attention of the audience, which then can enhance the audience's viewing experience.

도서관은 공공서비스 중에서도 강제적인 서비스가 아니고 임의적인 또는 생활의 질과 관련되는 서비스이기 때문에 서비스 수요는 접근용이성이나 주변환경 등의 영향을 받게 된다. 그러나 지금까지 우리나라의 공공도서관의 입지결정은 정책결정자의 의지나 경험이 크게 작용하여 이용자의 이용측면을 고려하지 않고 설립되었다. 본 연구는 공공도서관의 입지와 이용과의 관련성을 밝히기 위하여 이용자가 인지하는 접근용이성과 주변환경의 주관적 인지도를 측정하고 이용이 높은 도서관과 이용이 낮은 도서관간의 차이를 밝힘으로써 앞으로의 공공도서관의 입지선장에 유용한 자료를 제시하는 데 그 목적을 두었다.

The touch screen phone launched domestically in Korea, unlike the existing plane UI, it applied a cubic shape of 3D UI which provides three dimensional solid graphic. This study proposes to examine the correlation between the users' experience of 3D GUI, which were made by two different companies, and the brand. From this point of view, this study sets up a hypothesis about intimate correlation between individual differentiated brand and the user experience. Base on that, a model was designed. This study measured the satisfaction of user experience through the disclosure and non-disclosure of brand, focusing on 3D GUI cases which were launched so far, and it demonstrated that there was a clear difference in the degree of satisfaction. Through this examine, a brand was confirmed as one of the important element of user experience in using the 3D GUI that was launched competitively by companies. Therefore, the result of this study suggest that the designers need to establish strategies that make the brand as the core subject of design during the process of manufacturing product and service.
