현재 우리생활은 언제 어디서나 네트워크에 접속하여 통신할 수 있는 유비쿼터스 컴퓨팅 환경화 되고 있다. 이러한 환경에서 상황인식 서비스는 의료, 여행, 가정, 교육 등 사회 전 분야에 걸쳐 응용될 수 있어 사회 전반에 걸쳐 영향을 주고 있다. 기존의 대부분의 상황인식 시스템의 연구들은 센서로부터 입력된 주변 환경 정보를 기반으로 사용자에게 적합한 서비스 제공에 중점을 두고 있다. 이로써 환경정보와 별개로 사용자가 궁극적으로 원하는 분야에 상황인식 시스템을 적용하기 위해서는 서비스 부합되지 않은 여러 요소가 존재하였다. 본 논문에서는 이러한 요소를 착안하여 사용자의 의도를 포함한 상황인식 시스템을 제안한다. 제안된 시스템은 지능형 홈 도메인 환경에서 시간에 따라 변화하는 사용자의 행위 정보를 기반하여 사용자가 향후 궁극적으로 원하는 의도를 예측 할 수 있는 시스템으로 되어있다. 또한 여러개의 작은 행위에 따른 사용자의 의도가 모여 보다 큰 사용자의 의도를 파악하는 기법을 정의하였다.

This study analyzed faculties' perceptions on the importance and performance of effective teaching behaviors. The effective teaching behaviors scale consisted of 40 items belonging to 8 factors. A survey was conducted with 86 faculties from 2 universities. It was found that the differences between the importance and performance levels of all items except for 'applying emphasis on important contents' were statistically significant. The scores of importance were higher than those of performance. The results of the IPA showed that 'keep up the good work' area included 19 items that those were high the scores of importance and performance. The 'concentrate here' area included 5 items that need to be improved for effective teaching. The first priority items needing to be improved were 1) Establishing instructional methods and strategies suitable for the objectives, 2) establishing clear objectives, appropriate examples and systematic classes, 3) providing questions, opportunities and appropriate feedback. We suggested that a faculty development program needs to be developed for effective teaching.

This study set up a purpose in the efficient utilization of security target objects. This purpose is the following: Firstly, this study analyzed problem about deleted areas for security described on aerial photography image. Secondly, this study made clustering and labeling to recognize censored areas of image. Finally, this study tried to maximize various utilizability of digital image data through postprocessing algorithm. Based on these courses, the results of this study appeared that brightness value of image increased depending on topography and quantities of topographic features. It was estimated that these was able to utilized by useful estimative data in judging information of topography and topographic features included in the total image. Besides, in the image recognition and postprocessing, the better result value was not elicited than in a mountainous region. Because it was included that a lots of topography and topographic features was similarly recognized with the process for deletion of the existing security target objects in urban and suburb region. This result appeared that the topography and quantities of topographic features absolutely affected the recognition and processing of image.

This study aims to analyze the level of members' awareness of records management in the Republic of Korea Army within the institutional context extensively. Accordingly, in-depth interviews were conducted after comparing and analyzing the institutional systems that restricted the members' record management activities. As a result, it was identified that the members were confused by the inconsistency among the systems that defined the work procedures, and that the value of responsibility and efficiency in the records management system does not match the organization's goals. Therefore, the legal justification of the system should be improved in harmony with the responsibilities and efficiency and to match them with the organization's objectives. Moreover, the improved system should be internalized by the members through instructions that are relevant to the content of the system. This study intends to increase awareness in the records management system and improve the system as well.

This paper proposes an efficient and accurate vision based recognition and tracking framework for texture free objects. We approached this problem with a two phased algorithm: detection phase and tracking phase. In the detection phase, the algorithm extracts shape context descriptors that used for classifying objects into predetermined interesting targets. Later on, the matching result is further refined by a minimization technique. In the tracking phase, we resorted to meanshift tracking algorithm based on Bhattacharyya coefficient measurement. In summary, the contributions of our methods for the underwater robot vision are four folds: 1) Our method can deal with camera motion and scale changes of objects in underwater environment; 2) It is inexpensive vision based recognition algorithm; 3) The advantage of shape based method compared to a distinct feature point based method (SIFT) in the underwater environment with possible turbidity variation; 4) We made a quantitative comparison of our method with a few other well-known methods. The result is quite promising for the map based underwater SLAM task which is the goal of our research.

After having changed its corporate brand from LG Fire & Marine Insurance to LIG Non-life Insurance in 2006, LIG Insurance has successfully built the corporate image as the leading insurance financial group by engaging in extensive corporate social responsibility activities. LIG, as 'a partner for sharing precious moments of life', intended to provide customers a new value of an insurance by building up the new corporate brand. It established three values to be shared internally. First was to instill a brand value orientation within the organization. Second, the firm identified the brand's value to be delivered to the customers. Third, they defined the image objective to be communicated to them. Based on these set of objectives, the company designed and implemented an integrated marketing communication(IMC) strategy over several years. The result was a successful transition to the new corporate brand name.

세대간 통합 프로그램은 1980년대 이래로 외국 사회노년학 분야뿐만 아니라 아동학분야에서 점차 관심이 높아지는 주제이다. 이러한 프로그램은 양 세대간의 올바른 이해를 통하여 긍정적인 관계향상을 도모한다는 분명한 목표를 갖는다 일반적으로 아동은 노인에 대하여 매우 부정적인 태도를 가지며, 노화과정에 대하여도 두려움을 느낀다고 보고되고 있다. 이에 본 연구는 세대간 통합 프로그램이 아동의 노인인식에 영향을 미치는지를 조사하고자 하였다.

The image of science is one of the recurrent topics in science education research. In particular, we believe that students' images of Doing-Science-Well could be used for identifying not only students' perceived goals of science learning, but also practical guidelines of effective science teaching. In this study, the students' images of Doing-Science-Well were investigated with the following two research questions: (i) what are student's images of Doing-Science-Well?; (ii) in what contexts do students perceive that someone is doing science well? Thirty seven students in a high school in Seoul, Korea were asked to write their personal experiences by which they realized that someone was doing science well. The main results of the study are the following: Firstly, the images of Doing-Science-Well could be categorized into 'Einstein type', 'Socrates type', 'MacGyver type' and six more types. Secondly, with regard to contexts, students tended to realize that somebody is doing science well in terms of two kinds of contexts: 4 physical contexts and 6 psychological contexts. The findings led us to develop a frame of judging Doing-Science-Well, which combines the types and two kinds of contexts. The frame illustrates the multiplicity of the images of Doing-Science-Well.

웹 마이닝은 e-서비스 시스템에서 고객 활동을 분석하기 위하여 널리 보급된 방법 중 하나로서 궁극적인 목표는 새로운 고객을 얻고 기존 고객을 유지하면서 고객의 생산성을 증가시키는데 도움을 줄 수 있는 유용한 정보를 인식하는 것이다. 그러나 웹 로그 자료와 고객의 구매 패턴 사이에 직접적인 관계가 없고, 실험 데이터 집합이 적고 부정확 할 경우 실험 데이터의 적은 집합만으로 유용한 정보를 인식하는 것은 불충분하기 때문에 유용한 정보를 인식하는 것은 더욱 어렵게 된다. 본 논문에서는 기업들에게 유용한 패턴을 제공할 수 있는 독자적인 분류 방법을 사용하여 기존 고객의 보존력을 높일 수 있는 높은 정확도를 가지는 소형 트리를 구축할 수 있었다.
