This paper is to identify how merchandise quality, store environment, personnel service, sales promotion, store amenities and supporting service which is considered to store image components influence on satisfaction and loyalty and examine the role of satisfaction in explaining relationships between store image and loyalty. The results of the study are as follows: (1) each components of store image influence on cognitive satisfaction or emotionally based satisfaction or loyalty. (2) merchandise quality and store amenities have influence on cognitive satisfaction and emotionally based satisfaction is affected by personnel service and supporting service, but store environment has directly influence on loyalty. (3) store image components that is concerned with service in the store e.g. personnel service, supporting service build customer loyalty by mediating emotionally based satisfaction. In order to build strong customer loyalty, marketer have to formed through store image components that is much stronger on loyalty.

본 논문은 이미지 완성(Image Completion)을 위한 근사적 에너지 최적화 알고리즘을 제안한다. 이미지 완성이란 이미지의 특정영역이 지워진 상태에서, 그 지워진 부분을 나머지 부분과 시각적으로 어울리도록 완성시키는 기법을 말한다. 본 논문에서 이미지 완성은 유사-확률적(pseudo-probabilistic) 시스템인 Markov Random Field로 모델링된다. MRF로 모델링된 이미지 완성 시스템에서 사후 확률(posterior probability)을 최대로 만드는 MAP(Maximum A Posterior) 문제는 결국 시스템의 전체 에너지를 낮추는 에너지 최적화 문제와 동일하다. 본 논문에서는 MRF의 최적화 알고리즘들 중에서 Belief Propagation 알고리즘을 이용한다. BP 알고리즘이 이미지 완성 분야에 적용될 때 다음 두 가지가 계산시간을 증가시키는 요인이 된다. 첫 번째는 완성시킬 영역이 넓어 MRF를 구성하는 정점의 수가 증가할 때이다. 두 번째는 비교할 후보 이미지 조각의 수가 증가할 때이다. 기존에 제안된 Priority-Belief Propagation 알고리즘은 우선순위가 높은 정점부터 메시지를 전파하고 불필요한 후보 이미지 조각의 수를 제거함으로써 이를 해결하였다. 하지만 우선순위를 정점에 할당하기 위한 최초 메시지 전파의 경우 Belief Propagation의 단점은 그대로 남아있다. 이를 개선하기 위해 본 논문에서는 이미지 완성을 위한 MRF 모델을 피라미드 구조와 같이 층위로 나누어 정점의 수를 줄이고, 계층적으로 메시지를 전파하여 시스템의 적합성(fitness)을 정교화 해나가는 Hierarchical Priority Belief Propagation 알고리즘을 제안한다.

This study is to analyze the effects on using robots in elementary regular classes. The robots and PC-linked applications were developed considering the school subjects' academic goals and the learners' responses were carefully examined while applying the robots in the class. The image profile after the robot application shows positive feedbacks in most of the contents and some significant differences were found in contents such as 'theoretical-practical', 'uncooperative-cooperative'(p<.05). Moreover, the analysis on the learners' image drawings shows that more robot images are formed related to the concrete learning environment. The learners have answered in an interview to evaluate their understanding of Robot based instruction that both direct and indirect robot experience induce positive participations and provide authentic learning experience. During the robot based instruction, the learners cooperate with their group members and recognize the cooperation as a positive activity. It proves that the robot based instruction can lead to a possibility of new education paradigm.

The purpose of this study was to examine whether corporate sports marketing strategy using professional teams changes corporate image. In particular, this study was intended to analyze the effects of origin and corporate reputation on the change of corporate image in the process of persuading corporate image. Finally 211 effect data were secured by pre-test and post-test. The change of corporate image and the moderating effect of origin perception and corporate reputation were analyzed. The results were as follows. First, corporate trust image and social contribution image showed statistically significant increase. Second, corporate image had a difference before and after the test according to origin perception and after the test, corporate trust image and social contribution image were increased. Third, corporate image had a difference before and after the test according to corporate reputation. After the test, corporate trust image and social contribution image were increased and trust image confirmed the mediating effect according to corporate reputation. Based on the findings, this study suggests that corporate sports marketing strategy using professional teams has an effect on the persuasion of corporate image. Moreover, it demonstrates that the strategy is an important marketing tool to change consumers' corporate image.

우리는 석굴암에서 기능을 수용하는 건축물의 완전한 전형으로서 공간과 그 공간에 합치되는 내용물의 이상적인 결합을 보게되는 바, 그러한 이상적 공간이 인간들의 자파세계가 아닌 신들의 세계 즉 극락정토임은 합당한 일이다. 필자는 여기서 제작자가 단지 시공방법만을 고분에서 모방한 것이 아니라, 사후의 기대 공간인 극락정토의 이미지를 의도적으로 결합하고자 시도한 것이라 짐작한다.

In the process of finding the triangle height, 26 students in the 6th grade were surveyed to understand the students' triangle height through the eye movement data and to investigate the cognitive load of the students. As a result, the correctness rate of the pre-test was significantly increased in the post-test, and the frequency and retention of gaze data were smaller in the post-test than in the AOI of each question. The Participants's subjective cognitive load indicated that it was more difficult to understand the concept of rotated triangles compared with upright triangles that were parallel to the ground. More frequent and more retentions in the eye-tracking data were detected in the right triangles and acute triangles by rotating configuration. Eye movement data show that eye tracking technology can provide an objective measure of students' cognitive load for feedback on instructional design.

This study investigated the effects of the 'Meeting With Scientists' program on children's stereotypical images of scientist. To do those, 36 children of a fifth grade class participated in the program for one month. The program consisted of two main activities:(l) participating in scientists' lectures and exchanging e-mail with them; and (2) visiting web sites about scientist and science, and exchanging e-mail with scientists at the sites. The results of the study can be summarized as follows: First, after participating in the program, children showed the significant decrease of several stereotypical items, such as facial growth of hair(bald hair beard), symbols of research, and age of the scientist. Second, the most popular source of the images was the visual media at the pretest but the source was changed to the visiting and participating scientist's lecture, and internet at the posttest. The latter items appeared a significant difference between the pretest and the posttest, The results indicate that the program is effective to decrease of children's stereotypical physical image of scientist.

기존의 규칙기반 침입탐지 시스템은 사후처리시 규칙 추가로 인하여 새로운 변종의 공격을 탐지하지 못한다. 본 논문에서는 규칙기반 시스템의 한계점을 극복하기 위하여, 시간지연 신경망(Time Delay Neural Network; 이하 TDNN) 침입탐지 시스템을 제안한다. 네트워크강의 패킷은 바이트 단위를 하나의 픽셀로 하는 0에서 255사이 값으로 이루어진 그레이 이미지로 볼 수 있다. 이러한 연속된 패킷이미지를 시간지연 신경망의 학습패턴으로 사용한다. 정상적인 흐름과 비정상적인 흐름에 대한 패킷 이미지를 학습하여 두 가지 클래스에 대한 신경망 분류기를 구현한다. 개발하는 침입탐지 시스템은 알려진 다양한 침입유형뿐만 아니라, 새로운 변종에 대해서도 분류기의 유연한 반응을 통하여 효과적으로 탐지할 수 있다.

인터넷과 통신기술의 급격한 발전으로 인한 디지털 컨텐츠의 저자 동의 없는 복사 배포의 증가는 저작권 침해 및 불법 복제 및 배포, 위조 등의 문제를 발생시켰다. 이러한 저작권 문제를 해결하기 위한 사후적 방법으로 디지털 워터마크 기술이 개발되었다. 본 논문은 이산 웨이블릿 변환의 트리플린 특징을 이용한 바코드 이미지 워터마크 알고리즘을 제안하였다. 바코드 이미지 워터마크에 일정한 패턴을 이용하여 여러 공격에 강인성을 갖게 하였다. 또한 워터마크 추출시 상관도를 구하지 않아도 시각적으로 워터마크의 삽입 여부를 확인 할 수 있으며, 낮은 상관도에서도 워터마크를 시각적으로 확인 할 수 있는 장점을 갖는다.

This study has the purpose of examining the effect of the festival post image on the satisfaction and loyalty of tourists in terms of revisit and recommendation for Baekjae Cultural Festival. The questionnaires for the survey were distributed among 287 visitors of Baekjae Cultural Festival. For the empirical analyses, frequency analysis, reliability analysis, factor analysis, and multiple regression analysis were used based on the conducted survey. The results are as follows: According to the analyses, five factors were drawn such as regionality, convenience, amusement, cultural characteristic of Baekjae, and management. According to the hypothesis testing, convenience, regionality, and amusement affected tourists' satisfaction for the festival, while convenience and amusement influenced revisit intention of the tourists. On the other hand, significance, convenience, and cultural characteristics of Baekjae affected recommendation intention for the festival. In conclusion, amusement & novelty and cultural characteristic of Baekjae were the factors that festival post image affected the satisfaction and loyalty of tourists in terms of revisit and recommendation for Baekjae Cultural Festival.
