Empathy has been observed to be pivotal in enhancing both social relations and the efficiency of task performance. Empathetic interaction has been shown to begin with individuals mirroring each other's facial expressions, vocal tone, actions, and so on. The internal responses of the cardiovascular activity of people engaged in empathetic interaction are also known to be synchronized. This study attempted to objectively and quantitatively define the rules of empathy with regard to the synchronization of cardiac rhythm between persons. Seventy-four subjects participated in the investigation and were paired to imitate the facial expressions of their partner. An electrocardiogram (ECG) measurement was taken as the participants conducted the task. Quantitative indicators were extracted from the heart rhythm pattern (HRP) and the heart rhythm coherence (HRC) to determine the difference of synchronization of heart rhythms between two individuals as they pertained to empathy. Statistical significance was confirmed by an independent sample t-test. The HRP and HRC correlation(r) between persons increased significantly with empathy in comparison to an interaction that was not empathetic. A difference of the standard deviation of NN intervals (SDNN) and the dominant peak frequency decreased. Therefore, significant parameters to evaluate empathy have been proposed through a step-wise discrimination analysis. Empathic interactions may thus be managed and monitored for high quality social interaction and communication.

Architectural evidence of Gaya is insignificant than any other area. In this situation, house-shaped earthenware is particularly helpful in the study of Gaya architecture. However, house-shaped earthenware is not a building, it has just the shape of buildings. So, we have to find out architectural evidence from that. In this paper, I tried to estimate the architectural characteristics of Gaya through house-shaped earthenware in detail. I also consulted historical records, archeological results, and other scholars' papers. The results are as follows. First, house-shaped earthenware can be classified into three types according to its shape, and each type has distinct architectural structural characteristics. Second, house-shaped earthenware generally has a gambrel roof, and the characteristic of architectural design with the gable side of the gambrel roof as a front is the biggest feature of Gaya architecture. Third, various types of buildings existed according to their functions in Gaya architecture, and house-shaped earthenware was showed buildings of ancient storage, pens, and residences, which are symbols of the richness among various types of buildings.

One of the interesting social phenomena in short-form video platforms is the hashtag challenge wherein ordinary users are encouraged to create by imitating short viral videos on a particular theme. Despite the increasing popularity of hashtag challenges, theoretical discussion on related user behavior is still very insufficient. In this study, we attempted to examine the impact of micro-influencers in order to understand users' willingness to participate in hashtag challenges. For this purpose, the para-social interaction theory and imitation behavior literature were adopted as key theoretical basis. In an empirical investigation using 243 survey data from TikTok users, our study found that a user's illusion of intimacy with a micro-influencer (i.e., para-social interaction) had significant positive impact on the intention to participate in a hashtag challenge. This study also showed that the degree of para-social interaction in a short-form video platform was determined by both media content-related factors and media character-related factors (i.e., content attractiveness, physical attractiveness, and attitude homophily). Our work in this study provided significant theoretical and practical implications on how to leverage micro-influencers for the success of hashtag challenges in a short-form video platform.

The intelligent product is a product in which interactive technologies are applied to an existing common product, called a mother product. This study focuses on interaction design of a hedonic intelligent product and investigates an efficient method of input control of hedonic intelligent products. The hedonic intelligent product is a product in which the hedonic attributes such as play and pleasure are added to the mother product. Utilitarian intelligent products enhance practical functions of mother products. The utilitarian intelligent product finds user behavior in the mother product to improve functional elements for a user experience design. On the other hand, hedonic intelligent products find various emotional values that impart hedonistic attributes and apply them to design. The input method studied through the case study is classified into the imitation input method and the transformation input method derived from the mother product. Based on this, two independent variables of intelligent pinwheels were designed, and its usability evaluation was conducted under the same output condition to investigate a more effective input method. As a result, the transformation input method was rated higher in originality than the imitation input method. This result implies that users had new experiences from the transformation input method, which leads to a higher intention of paying for new experiences.

1990년 초 일본의 Shingosen이 출현 이후, 합성 섬유가 갖는 일련의 장점을 유지하면서 천연섬유의 특성을 모방한 폴리에스테르 극세섬유의 등장으로 고급화 및 차별화 된 폴리에스테르 섬유의 상품 추구가 가능하게 되었다. 근래에 와서 통상적인 방법으로 얻어지는 극세사(Micro fiber)는 약 1d이며, 현재에는 보통사와는 전혀 다른 고도의 유연성$\boxUl$ 촉감, 외관을 가지는 0.3d이하의 공업적 방사도 가능하게 되었다. (중략)

지적재산권법은 발명, 저작물, 상표, 의장 등에 대한 독점을 허용하는 점에서 독점을 금지하는 독접규제법과 대립되는 것처럼 보인다. 그러나 지적재산권법이 인정하는 독점은 무조건적인 것이 아니라 내용과 기간에 있어서 제한적인 것이다. 또한 경쟁자에 의한 부당한 모방행위를 금지시켜 궁극적으로는 경쟁질서를 유지하게 된다는 점에서 지적재산권법과 독접규제법이 양립불가의 것이라고 할 수는 없다. 오히려 양 법영역은 모두 국민경제와 국가산업발전을 목적으로 한다는 점에서 공통되므로 양자를 모순 없이 공존케 하는 것이 중요하다. 이 둘은 법 형식적으로 충돌하는 것처럼 보이지만 실제로 거시적인 목적에서는 상호 보완관계에 있으므로 조화롭게 운용하는 것이 앞으로의 경쟁정책수립에 꼭 필요한 요소이다.

복식은 의상뿐만 아니라 헤어스타일에서 신랄에 이르기까지 인간을 장식하는 모든 영역을 포함하고 있으며 특히 토탈패션화 현상이 대두되면서 매우 중요시되고 있다. 특히 복식 중 헤어스타일은 얼굴을 강조하고 우리의 인상을 결정해 주는 중요한 부분으로 다른 복식과 더불어 별도의 영역으로 발달되면서 독특한 상징체를 이루고 있다. 또한 헤어스타일은 대중을 중심으로 빠르고 넓게 그 영향력을 확장해 감으로써 인간의 생활과 밀접한 예술이자 사회 문화적 기능의 한 형태로 자리하고 있다. (중략)

본 논문에서는 박테리아의 주화성에 기초한 Bacteria Cooperative Optimization(BCO) 알고리즘을 소개한다. BCO는 Ant Colony Optimization (ACO)처럼 자연계에 존재하는 생명체의 행동양식을 모방하여 만든 최적화 알고리즘으로 크게 초기화, 측정, 행동결정, 이동으로 구성된다. 우리는 먼저 BCO 알고리즘을 설명하고 2차원 함수 최적화 문제를 이용하여 BCO알고리즘과 Genetic Algorithm(GA) 그리고 Bacterial Foraging for Distributed Optimization(BFO)의 성능 측정 결과를 기술한다. 실험 결과 BCO의 성능이 GA나 BFO보다 우수함을 보였다.

1990년 초 일본의 Shingosen이 출현하면서 범용화하고 있는 폴리에스테르 섬유가 고부가가치 상품으로 변신하게 되는 계기를 맞게 되었다. 합성 섬유가 갖는 일련의 장점을 유지하면서 천연섬유의 특성을 모방한 폴리에스테르 극세섬유의 등장으로 고급화 및 차별화 된 폴리에스테르 섬유의 상품 추구가 가능하게 되었다. 근래에 와서 통상적인 방법으로 얻어지는 극세사(Micro Fiber)는 약 1d이며, 현재에는 0.3d의 공업적 방사도 가능하게 되었다. (중략)
