In this study, we designed and developed a tool to help teachers select and develop effective performance assessment criteria considering characteristics of individual learners. Using this tool, we can analyze preferences of teachers and characteristics of students for each rubric by exploring the classification and association rules through data mining. Those findings can give us guidelines and insights for the development and the selection of performance assessment criteria. The classification rules found are used for the learner-centered evaluation reflecting learners' interests, capabilities, and circumstances. Association rules found are utilized for analyzing teachers' preference, which enable to reduce time and efforts for the development and selection of rubric. Also, this tool supports creation, change, and selection of teachers' rubric linked with the performance assessment of NEIS(National Education Information System).

폭력의 발생 원인은 다양하고 그 표현 방식도 여러 가지 양상으로 나타나지만 인간의 기저에 갖고 있는 일반적 원인은 욕구불만이다. 욕구불만의 해소가 이루어지지 않은 상태에서의 인간은 항상 폭력성이 잠재되어있는 상태가 된다고 볼 수 있다. 윌리엄 맥두걸은 본능이 인간행동에 동기를 부여하는 가장 중요한 요인이며, 지각과 정서보다 동기의 힘을 강조했다. 사람은 본능이 동기를 부여해 준 것을 지각하고 적절한 대상이 지각되면 그 대상은 행동을 자극하는 감정변화를 일으킨다. 이러한 검정변화를 충동이라 할 수 있는데 지그문트 프로이드는 인간의 많은행동이 불합리한 본능적 충동에 바탕을 둔다고 보고 있다. 충동은 대개 생리적인 긴장, 결핍,또는 불균형상태에 뿌리는 두며 충족되어야 할 절박한기본 욕구로 유기체에 행동을 강요한다. 충동은 선천적이며, 기본적인 생리적 욕구와 직접적으로 관련된 충동과 학습을 통한 모방충동, 약물복용의 반복적으로 인한 양물중독이 있고, 성취, 활동, 친화, 호기심, 배설, 탐구, 조작, 모성애, 고통회피, 성애, 수면 등 인간의 생활에 반영되는 거의 모든 욕구를 포함한다. 따라서 욕구의 해소를 위해 무엇인가를 해야만 하는 인간은 욕구의 억압상태나 좌절상태에서 심한 분노와 폭력의 충동을 느끼게 된다. 현대 심층심리학은 어린이들이 말을 충분히 자유자재로 구사하기 전에 겪고 억누르게 된 무시무시한 분노의 환상을 가지고 있는데,. 공포예술의 무시무시한 영상들이 결부되어있다는 것이 밝혀졌다. 픽카드(P.M. Pickard)에 의하면 어린아이는 그들의 내적 현실을 외적 현실을 적응시키려는 힘겨운 투쟁 속에 근친상간적 갈등, 흡혈귀, 살인, 식인 등 끔찍한 환상을 겪는 것 간다고 한다. 청소년기는 사회적 부적응기로서 현실과 어릴 적 꿈꿔왔던 이상과의 괴리감에서 오는 당혹과 분노가 발생되는데, 이 시기에 많은 청소년들이 극단적인 선정적인 폭력성에 탐닉하게 되는 경향이 있다. 현실은 결코 아름답지 못하고, 행복하게 살 수 없다는 것에 대한 깨달음에서 기인한다. 욕구불만의 강도가 심해질수록 폭력성은 더욱 강하게 나타나는데 개인에게서 뿐만 아니라 가족, 동료, 사회 단체나 종교, 국가간에도 집단적으로도 발생하게 된다. 사회적으로 볼 때 폭력은 용인되는 것이 아니므로 도덕적으로 절제를 하거나 상대방과 적절한 타협과 조정을 필요로 한다. 그러나 절제의 한계를 넘어선다고 생각되거나, 조정의 노력이 불가능하거나, 실패했을 때 폭력적인 행동으로 나타나게 된다. 리차즈(I.A Richards)는 분노와 공포는 일단 겉잡을 수 없는 경향이 있다고 하면서 오늘날 폭력에 대한 요구가 일상의 정서 생활에 있어, 억압을 통한, 빈곤함을 반영하고 있지 않은지 생각해봐야 할 것이라고 충고한다.

In this research, we observed how students perform as they followed the teachers' instruction, and consequently perform their realized potential. As the accountability of school education is emphasized, various attempts try to disconnect the vicious cycle of producing low achievers. Efforts are allocated into developing a method to minimize cumulative effect of the lag in educational benefit by focusing on the elementary education. Based on the 2007 revised curriculum, mathematics achievement level and assessment criteria were developed. These criteria were used to standardize the course and assessment objectives for 4th through 6th grade students' mathematics studies, and to assess lower performing students and the lag in their mathematical understanding. The educational materials and assessment criteria can be expected to lead lower performing students by giving them the personalized lesson plans to minimize the lag of mathematical understanding, and eventually expedite their progress and prevent cumulative effect of the lag in the following curriculum.

One of important factors for improving the learning achievement of students in computer programming education is to provide plenty of opportunities of problem-solving experiences through variety forms of assignments, However, for the most cases, evaluation of programming assignments is performed manually by instructors and automated tools for the accurate evaluation are not equipped at the present time. Under this restricted environment instructors need much work and time to grade assignments so that instructors could not deliver sufficient programming assignments to students, In order to overcome this problem. au automated programming assignment evaluation system is needed that would enable instructors to evaluate assignments easily in an effective and consistent way and also to detect any plagiarism activities among students in program source codes readily, Accordingly, in this paper we design and implement a Web-based programming assignment grading system that allows instructors to evaluate program performance automatically as well as to evaluate program styles and piagiarism easily with appropriate feedback.

This study attempts to review and evaluate the sociological engagement and media practices of an eminent French sociologist Pierre Bourdieu. In the first part of the paper, I presented some characteristics of Bourdieu's view on the sociological engagement. In the second part, I also examined Bourdieu's alternative media strategies(ARSS, Liber, Raisons d'agir) which were designed to intervene effectively in the academy and public sphere of French society. For Bourdieu, the sociological engagement can be conceived and legitimized as follows: first, the talents of the ensemble of 'specific intellectuals' in Foucaldian sense should be combined to constitute a kind of 'large collective of intellectuals' Second, this 'collective of intellectuals' should make 'corporatist' efforts to improve the autonomy of the 'field of cultural production', which is the indispensable condition for the conquest of 'the universal' Bourdieu tried to realize his logic of sociological engagement through all his intellectual works, media activities and political intervention. In appreciating positively the consistency and originality of Bourdieu's theory and practice of engagement, I proposed to reconsider some limits of his 'modern' politics - enlightenment, science, collectivity - in today's 'postmodern condition'.

Terrorism has existed in the entire human history and has become a significant topic in criminology while prior studies has focused on North Korea as the perpetrator, and this prevents an in-depth discussion of the international trends of terrorism. As soft targets are the main target of new terrorism and because we never ignore the significance of the consequences, there are needs for more studies on the topic. This study conducted a case study of major terrorism attacks and surveyed professionals in the field via an AHP analysis in order to find the characteristics of terrorism and its potential patterns in South Korea. As a result, we found that North Korea or the left-wing may utilize homemade bomb, motor vehicle or drone for the purpose of attacking multi-use facilities in South Korea. For policy implications, we insist developing a better CPTED approach on those facilities, improving professionalism of cyber-watchdog via more training and education, stricter control on drone permit, and operation of counseling centers for preventing radicalization.

As CCTVs are widely utilized in diverse fields, many researchers have continuously studied to improve the surveillance performances of a CCTV system. However, an quantitative evaluation approach about the surveillance performance has rarely been researched. Therefore, we set up the research for suggesting a quantitative evaluation approach to determine the effectiveness of CCTV coverages. We firstly defined the surveillance resolution as that varies according to object's positions and orientations. Based on the definition, we computed surveillance resolution values at all three-dimensional positions with the orientations of interests in the specified space. By comparing these values to the required reasonable resolution, we determined the surveillance performance index indicating how well a CCTV system monitor a target space for specific surveillance objectives. This proposed approach evaluates the surveillance performance of a CCTV system quantitatively, so as examines the CCTV system design before its installation based on precise 3D spatial analysis.
