Rational debate and public conversation in the public sphere of social network are crucial conditions for realizing deliberative democracy. However, negative communication can occur online more frequently than in the real space, and mutually hostile messages are appearing. In the electoral process, citizens combining for particular candidates have made personal attacks against, abused and slandered the opposing candidates. Then, how and to what degree has the flaming behavior been appearing in the elections? Are there influencers to propagate the flaming behavior? And how flaming are these influencers, compared to internet users? This research focuses on the flaming behavior which occurred during the reelection for Seoul Mayor, in order to diagnose the role of social network as an online public sphere. This study analyzes the spreading degree of flaming messages depending on each issue, and the differences of messages between influencers and normal users. There was frequent flaming behaviors to distribute biased information which criticized, laughed at and maliciously attacked individual candidates. Moreover, influencers who advanced leading opinions, displayed a higher flaming degree than normal users.

본 연구에서는 고등학교 지구과학 교과서 분석을 통해 지구과학 그래프의 주요 유형과 특징을 파악하고 지구과학 그래프 관련 검사지를 제작, 투입하여 고등학생들의 지구과학 그래프 해석 능력과 인식을 분석하였다. 지구과학 그래프는 타 과학 과목에 비해 그래프의 수가 많고 그 유형이 다양했다. 특히, 선 그래프와 등치선도가 많았으며, 선 그래프 중에는 다중 선 그래프와 YX 그래프 등의 비율이 높았다. 고등학교 2, 3학년생 111명을 대상으로 한 검사지 1단계에서는 '마그마의 생성 조건', '지구 자기장의 영년 변화', '과냉각 물방울과 빙정의 포화 수증기압', 'H-R도' 등에 관한 문항의 정답률이 특히 낮았다. 검사지 2단계에서는 약 $56\%$의 학생들이 지구과학 그래프의 유형이 타 과학 및 수학 과목의 그래프와 차이가 있다고 응답했다. 검사지 3단계에서는 동일한 내용이라 하더라도 그래프의 형식이나 구체적인 표현 방법에서 학생들의 이해를 높일 수 있는 방안에 대한 고민이 필요함을 알 수 있었다. 본 연구에서 학생들은 '그래프의 유형'에 대한 이해가 다소 부족하고 자신에게 익숙한 그래프를 쉽다고 생각하는 경향을 보였다. 따라서, 과학 교육자나 과학 교육과정 설계자들은 학생들에게 그래프 연습의 기회를 많이 부여하고, '그래프' 자체에 관한 교육은 물론 지구과학의 학문적 특성과 관련지어 '그래프의 유형'에 관해 체계적인 교육을 해야 할 필요가 있다.

It is required that public schools in information society should act as a balancer between the equal educational opportunity and development of the personal capacity. However, public schools have faced a situation to be blamed and praised by social parties concerned from the point of view of educational excellence. The aim of this study is to suggest some conceptual ideas for sharing & delivery system of educational information, which is based on the paradigm of web 2.0 characterized as participation, sharing, and openness. To do it, we analyzed the recent technological trends and took a group discussion with leading teachers in educational information.

In this study, we synthesized a self-photocuring intermediate(SPI) by Michael addition reaction and synthesized polyurethane acrylate oligomer. Analysis and physical properties of the synthesized SPI and polyurethane acrylate oligomer were confirmed by FT-IR, NMR and UTM. As the content of the SPI increased, the tensile strength increased and the elongation decreased. In addition, since the film was hydrophobic, the surface energy tended to decrease. When the content of the SPI was 40 wt%, adhesion, processability, and pencil hardness were excellent, and solvent resistance was excellent overall.

In a variety of fields, recently, there is a growing interest in Geographic Information System which facilitates efficient storage and retrieval of geographic information. It is of extreme importance to make a good choice of efficient input method, because it takes the most of the lime and cost in constructing a GIS. Among several steps, thinning input image to produce skeleton of unit width is prerequisite to the automatic input or geographic maps. In this paper, we systematically evaluate the performance of representative thinning algorithms in geographic maps such as contour, cadastral, and water and sewer maps, and suggest appropriate algorithms for the maps, respectively. A thorough experiment indicates that Arcelli's method is best for contour maps, Holt's method for cadastral maps, and Chen's method for water and sewer maps.

This is the second segment of an action research on the constructivist geography education.(1)Deeper and lasting construction of knowledge may be possible especially when some key or leading concepts are utilized, around which other related concepts may be further explored. (2) Graphic languages may be more pedagogically effective than any other language, when they are viewed as means of learning may be the teacher's questioning, cooperative discussion, and the teacher's guidance and assistance. The questioning by the teacher seems effective when it is appropriate to the different levels of learner's comprehension, and cooperative discussion among thern seems productive with the teacher's attentive guidance. And, (5) constructivism may best be understood when teachers try to embody it in their own classrooms. This may be part of the context in which action research is called for.

Since Korea started producing original animations targeting children, market of character for children has been led by TV animation with continuous broadcasting and OSMU. With a successful fondation in animation toy industry, its market is expanding to film industry, at the same time, brings positive effect for benefit of domestic animation. Therefore, this study researched viewing rate of children's TV animation and analyzed character storytelling to help foster and grow the direction of future animation characters. For the analysis, I selected 20 animations with high viewing rate and analyzed the storytelling of 95 characters based on their roles. The results of this study are as follows: in children's animation appeared various types of characters helping each other to make the viewer learn socializing. In addition, character's external setting varied depending on its role. Moreover, in the characters' internal setting, the most frequently appeared keyword was leadership, however, their personality keyword varied depending on the role.

Government is not only the biggest owner in public sector, but also the leader responsible for improving and fostering construction industry. Delivery systems and award methods are enacted as laws via government's strong will for construction innovation. In addition to establishing relationships between government and contractor, delivery systems and award methods affect every aspect of industry. Therefore, the government should keep trying to remove inefficiency and achieve Best Value. This paper analyzes the delivery systems and award methods of advanced countries to extract lessons for Korean industry focusing on leading parties, direction, and change in owner's awareness of their respective innovative movements for construction. The prerequisites for improvement in delivery systems and award methods are suggested as partnership between public and private sectors, consistent innovation, enhancement in efficiency, and reinforcement of owner's capability.

Nash Equilibrium (NE) is as useful tool for investigating a participant's strategic generation quantity in a competitive electricity market. Cournot model may give a mixed strategy NE instead of a pure strategy when transmission constraints are considered. A mixed strategy is difficult to compute, complicated to understand conceptually, and hard to implement in an electricity market practically. This paper presents that a mixed strategy does not appear in Stackelberg leader-follower model even under a transmission congestion. A solution method is proposed for the leader-follower model under a nondifferentiable space of a strategy variable. Based on the pure strategy NE with a transmission line congested, the merit of leader-follower model is shown from a social welfare point of view.
