  • Emotion plays a key role in both generating and understanding narrative. In this article we analyzed the emotions represented in a movie script based on 8 emotion types from the wheel of emotions by Plutchik. First we conducted manual emotion tagging scene by scene. The most dominant emotions by manual tagging were anger, fear, and surprise. It makes sense when the film script we analyzed is a thriller-genre. We assumed that the emotions around the climax of the story would be heightened as the tension grew up. From manual tagging we could identify three such duration when the tension is high. Next we analyzed the emotions in the same script using Python-based NLTK VADERSentiment tool. The result showed that the emotions of anger and fear were most matched. The emotion of surprise, anticipation, and disgust, however, scored lower matching.

  • This study investigates the problems resulting from the Internet addiction policy management in South Korea and discusses a direction for rational policies by developing a system that facilitates interactive discussions among interest individuals and groups. The Korean society has experienced conflicts of interests among the government, the private sector and civil society in the policy. In addition, heightened competition among government ministries has led the Internet addiction policy management to be susceptible to how citizens respond to the claims of interested parties, thereby having the rationality of the policy management less count. To address these issues, this study investigates the current Internet addiction policy and explores the potential of new governance from a perspective of new institutionalism. This study suggests that the system of the Internet addiction policy should be restructured to transfer control over the policy from the central to local government and develop governance centered on the consensus of the government, the private sector, and civil society.

  • An understanding of the concentrated solar flux is critical for the analysis and design of solar-energy-utilization systems. The current work focuses on the development of an algorithm that uses the Monte Carlo ray-tracing method with excellent flexibility and expandability; this method considers both solar limb darkening and the surface slope error of reflectors, thereby analyzing the solar flux. A comparison of the modeling results with measurements at the solar furnace in Korea Institute of Energy Research (KIER) show good agreement within a measurement uncertainty of 10%. The model evaluates the concentration performance of the KIER solar furnace with a tracking accuracy of 2 mrad and a maximum attainable concentration ratio of 4400 sun. Flux variations according to measurement position and flux distributions depending on acceptance angles provide detailed information for the design of chemical reactors or secondary concentrators.

  • Recent discovery of colossal magnetoresistance (CMR) phenomena in perovskite manganese oxides has evoked great interest for its physical peculiarity and the possible industrial application. Besides manganese oxides, CMR phenomena is also observed in $Tl_2Mn_2O_7$ with pyrochlore structure and in Cr-based chalcogenide with spinel structure. In this paper, we have studied electronic structures of Cr-based chalcogenide spindles $Fe_{1-x}Cu_xCr_2S_4$ at x=0.0, 0.5, 1.0 using the linearized muffin-tin orbital (LMTO) band method within the local density approximation (LDA). The characteristic resistivity for x=0.0, 0.5 could be explained qualitatively in terms of the half-metalic electronic structure and the Jahn-Teller effect. Especially, the half-metallic nature appearing in the metallic temperature regime is well descibed by the proposed conduction model for x=0.0, 0.5, 1.0. We have suggested, based on the conduction model, that the CMR phenomena observed in these compounds are closely correlated with the obtained half-metallic electronic structure.

  • Optical Coherence Tomography (OCT) is a non-invasive imaging method that utilizes the optical scattering and interference for visualizing the surface as well as cross-sectional structures of tissue. OCT has been used for diagnosing diseases in early stage in various medical fields, but an application in cosmetics is still at early stage. In this study, OCT was adopted to evaluate skin texture and wrinkle. Results showed similar patterns of evaluation with PRIMOS in the assessment using replica. In addition, OCT produced smaller errors at different angles compared to the PRIMOS in the assessment using 3-dimensional models of wrinkles. The resolution of the image was also high enough to differentiate the images of before and after the application of makeup products. Possible use of OCT in the evaluation of fine wrinkle assessment was studied in this research. Further development of methods is necessary to provide more evidences of the effectiveness.

  • 미국에 이민 온 한 한국가정을(정씨 가족) 대상으로 세 번의 면담 (interview) 및 art session을 통해서 이 핵가족 및 확대가족을 다음과 같은 방법으로 분석하여 가족의 유형(family Pattern)과 관계된 이론적 모델(Theocratical model)을 理이해하고 변화되고 있는 Health Program에 있어 간호원이 "변화인자(change agent)"로써의 역활을 재발견하고자한다. 이러한 방법은 가족 및 간호과학에 새로운 접근법이며 간호의 영역이 얼마만큼 확대될 수 있는가를 나타내고 있다. (1) Toman의 Family Cnstellation 이론과 일치되는 점 및 일치되지 않는 점 (2) 한국인 핵가족에서 관찰된 비언어적 의사소통(non-verbal communication)및 이것과 Scheflen의 이론과의 관계 (3) family Theory Bowen의 "differentiation of self"와 "family projection Process"이론에 의한 분석 (4) 핵가족에서 관찰된 상호작용 유형(interactional pattern)을 분석 (5) Art Session을 통해서 관찰된 사항 및 Critique 결과적으로 이 핵가족은 사회적 가치관이 변화된데서 오는 갈등에 직면하고 있다. 우리 나라의 확대가족에서 강조된 경치관은 가족을 하나의 전체로써 보는 "우리 (we-ness)"였는데 이것은 일상사용하고 있는 언어에도 영향을 미치고 있는 것을 볼 수 있어 즉, "내 동생 (my sister)"이라고 하는 대신 "우리 동생 (our sister)"이라고 하는데 여기에서 언어가 뜻하는 의미와는 거리가 먼 것을 알 수 있다. 정씨 부부는 미국적 정치관을 인식해서 그들의 상호작용 유형을 긍정적이고 개방적인 토의방법으로(positive open-discuses) 접근해야 한다. 이 핵가족의 부부는 둘 다 유교사상이 강조된 가정에서 자라나, 이 부부가 결혼한지 오 년이나 되었으나 언어적 의사소통이 (verbal communication)굉장히 제한된 것을 쓸 수 있다. 인간의 경험들은 인간이 접하고 있는 사회와의 상호작용에 의해서 결정된다. 사회가 배화함에 따라서 가족도 변화할 것이다. "변화는 언제나 사회에서 부터 가족으로 온다. 이 변화는 절대 작은 단위에서 큰 단위로 오는 것이 아니다.…그러나 가족구조는(family structure) 환경이 변화함에 따라서 적응해야 한다."라고 Minuchin이 지적한 것 같이 정씨 부부가 직면하고 있는 여러 가지 갈등은 이 핵가족이 그들의 가치관 및 상호 작용유형을 변형(repattering) 시키므로써, 복잡하고 다양한 미국사회에서 성장할 수 있는 좋은 기회를 만들어 주고 있다. 세 번의 면담시간은 각 30분이었으나 Volume 생략한 것을 부기하여 둔다.

  • Memristor which is known as fourth basic circuit element has been developed recently but its electrical characteristics are not still fully understood. Memristor has the incremental and decremental feature of the resistance depending upon the connected polarities. Also, its operational behavior become diverse depending on its connection topologies. In this work, electrical characteristics of diverse types of serial and parallel connections are investigated using the HP $TiO_2$ model. The characteristics are analyzed with pinched hystersis loops on the V-I plane when sine input signal is applied. The results of the work would be utilized usefully for analyzing the characteristics of memristor element and applications to logic circuit and neuron cells.
