This experimental research explores effect of cognition desire as audience's factor, and attention as context factor on audience's acquirement of information and understanding. Most previous researches of media effect focuses on news contents of TV, Newpaper and Internet. However the number of researches on TV documentary which contains lots of information very limited, and It's difficult to find researches on effect of cognition desire and attention on audience. Therefore this research tries to find effect of cognition desire and attention on audience's acquirement of information and understanding through experiment of TV current documentary. For this experimental research, 2 groups of subjects composed of 135 university students were exposed to 2 different viedeo clips of TV current documantary, one with window buzz, the other without it, after designing cognition desire as internal factor of 2 groups. Questions which were designed to measure cognition desire, acquirement of information and understanding of message were asked and analysed. This research found that subjects with higher degeree of cognition desire showed higher degree of acquirement of information and understanding than subjects with lower degree of cognition desire. However the effect of attention on audience's acquirement of information and understanding could not be found.

The study confirmed the relationship between attractiveness and suitability in the relationship between the formativeness of creating the artistic form of a virtual influencer who acts as an advertising model, advertising attention, and advertising attitude. To confirm this, the subjects of the study were the MZ generation and X generation, which have a high rate of SNS use. The analysis method used SPSS statistics 27.0 and SPSS process macro version. The research results are as follows. First, it was confirmed that attractiveness and suitability fully mediate the relationship between formativeness and advertising attention. In the path of formativeness and advertising attention, the total effect was found to be higher than the direct effect, and it was confirmed that there was a double parallel mediation effect through attractiveness and suitability in the relationship between the formativeness of virtual influencers and advertising attention. Second, it was confirmed that formativeness affects the mediating variable, attractiveness, but attractiveness does not affect attitude toward advertising. Since formativeness affects suitability and suitability in turn influences attitude toward advertising, it was confirmed that there is a full mediating effect between these variables. According to these results, the parallel mediating effect of attractiveness and formativeness was not confirmed in the relationship between formativeness and attitude towards advertising. The above study is significant in that it presents academic implications and practical implications by examining the dual and parallel mediating effects of attractiveness and suitability in the relationship between formativeness, advertising attention, and advertising attitude variables, which are considered in the production of virtual influencers.

In this paper, a noise-tolerant generalized symmetry transform(NTGST) is proposed and implemented as a context-free attention operator for efficient detection of multi-object. In contrast to the conventional context-free attention operator based on the GST in which only the magnitude and the symmetry of the pixel pairs are taken into account, the proposed NTGST additionally takes into account the convergence and the divergence of the radial orientation of the intensity gradient of the pixel pair. Thus, the proposed attention operator can easily detect multiple objects out of the noisy and complex backgrounded image. Experiments are conducted on various synthetic and real images, and the proposed NTGST is proved to be effective in multi-object detection from the noisy and complex backgrounds.

A hue-based attention operator and a combinational integral projection function(CIPF) are proposed to extract the normalized regions of face and facial features robustly against illumination variation. The face candidate regions are efficiently detected by using skin color filter, and the eyes are located accurately nil robustly against illumination variation by applying the proposed hue- and symmetry-based attention operator to the face candidate regions. And the faces are confirmed by verifying the eyes with the color-based eye variance filter. The proposed CIPF, which combines the weighted hue and intensity, is applied to detect the accurate vertical locations of the eyebrows and the mouth under illumination variations and the existence of mustache. The global face and its local feature regions are exactly located and normalized based on these accurate geometrical information. Experimental results on the AR face database［8］ show that the proposed eye detection method yields better detection rate by about 39.3% than the conventional gray GST-based method. As a result, the normalized facial features can be extracted robustly and consistently based on the exact eye location under illumination variations.

An efficient multi face detection technique is proposed based on hierarchical context-free attention operators in which multiple faces are efficiently detected from a noisy and complex background. A noise-tolerant generalized symmetry transform (NTSGT) is applied hierarchically, as a context free attention operator, to the input pyramidal image for the high speed global location of the regions of face candidates (ROFCs) with a single mask. For the face verification, local NTGST is applied within each ROFC to confirm the existence of the detailed facial features. First, by globally applying NTGST which introduces the average pyramid method and focusing to the input image with complex background, ROFCs with recognizable resolution are detected robustly. Morphological operations are applied only to the each detected ROFCs to emphasize the facial features like eyes and lips. Then, eyes are detected by locally appling NTGST to the ROFCs and only faces are detected by verifying the existence of the geometrical features of the faces relatively to the location of eyes. The experimental results show that the proposed method can efficiently detect multiple faces from a noisy or complex background with 93.5% detection rate.

This study aims to explore which aspects of student agency have previously been studied and the ways agent practices have been investigated in learning communities in research on science education. Results reveal five aspects of agency related to students' actions in a learning community: epistemic agency, transformative agency, educated action in science, disciplinary agency, and material agency. We delineated how agency is captured in epistemic practices, as described in the literature on each of the aforementioned aspects. We also probed into the three approaches by which previous research has examined the practices of students as agents that construct learning communities. These approaches are (a) the investigation of students' actions as representative of the agency of an entire learning community, (b) the exploration of the effects of focused student action on the structure of activity, and (c) the investigation of interactions between students as agents. We discussed the implications of previous research on the basis of each approach to understanding the diverse features of student-centered learning communities. The present work contributes to the exploration and support of students' practices as agents in the learning communities in science classrooms.

우리 농산업에게 2012년은 그간 예견되었던 위기가 표면화되고, 그에 대한 도전이 구체화 되는 시기가 될 것이다. 우리 농산업의 변화에 있어서 주목해야 할 키워드는 (1) FTA, (2) 건강, (3) 치유농업, (4) 농촌에 대한 재인식, (5) 애그리비즈니스, (6) 다문화, (7)신 소비문화의 등장, (8) 기후변화로 총 8가지가 대표된다. FTA는 한-미, 한-EU, 한-중이 복합적으로 작용할 시기이며, 건강은 여전히 가장 관심이 높은 분야이고, 치유농업은 소외계층, 학교폭력에 대한 새로운 대안으로 부각될 것으로 예상되고, 주 5일제 전면시행에 따라 우리 농업 농촌에 대한 국민들의 인식전환이 이루어질 것으로 예상된다. 애그리비즈니스 분야에서는 상품, 콘텐츠, 서비스, 소통을 모두 갖춘 농가만이 성공할 수 있다는 것이 드러나는 한 해가 될 것이며, 다문화 가정의 경우, '함께 사는 우리'가 되는 과정에서 문제점과 새로운 해결책이 제시되는 한 해가 될 전망이다. 농산물 소비의 새로운 고객층으로 떠오른 젊은 지식인층에 의한 소비문화의 분화와 영원한 숙제인 기후변화도 주목해야 할 키워드이다.

SI 엔진의 연소특징은 비정상 난류 예혼합 화염이며 여기서 내부 유동은 직접 화염 전파에 영향을 미치며 난류와 거시적 유동의 패턴 모두 중요한 역할을 한다. 내연기관 연소에서 난류는 매우 중요한 역할을 하고 통상 엔진 속도($\approx$흡입유동 속도)에 비례하며 그 주요 역할은 고속 운전 시 해당 사이클 내에 연소가 완료되는 데 기여하지만 출력저하, 제어 및 측정 그리고 사이클 변동과 관련하여 실질적으로 난류 제어를 통한 엔진 성능 개선은 사실상 불가능하다. 실물 엔진의 성능 파라미터로 주로 유동의 거시적 거동이 사용되며 이 유동과 연료 분사계가 혼합기 분포 상태와 화염 전파 방향을 결정하여 최종적으로 엔진의 성능을 지배한다. 따라서 가시화를 통한 연소 진단도 이 현상에 주목할 필요가 있으며 거시적 파라미터를 성능에 연관하는 다양한 기법이 존재하고 이들은 매우 풍부한 데이터베이스를 통해 비교적 정확한 성능의 예측을 가능하게 하고 이 점에 주목한 엔진만 성공을 거두었다. 이 거시적 현상에 주목하여 가시화를 통해 성층화 현상을 실험적으로 해석한 예를 제시하였다. SI 엔진 가시화에서 기법보다 중요한 것은 현상의 이해이다. 이를 위해 성공적 가시화 진단을 위해서는 우선 현상에 대한 모델링이 필요하고 이 모델에서 가시화를 통해 규명 가능한 현상을 추출해 내는 것이다.
