The management of image information settles as an important field with the advent of multimedia age and we are in need of the effective retrieval method to manage systematically image information. This paper has complemented the problem caused by the absence of space information that is a weak point of the existing color histogram method by assigning regions of features, and raised accuracy by adding texture and shape information. And existing methods using multiple features have problems that the retrieval process is embarrassed because each weight is set up manually. So we has solved these problems by assignment of weight applying fuzzy integral. As a result of experimenting with 1,000 color images, the proposed method showed better precision and recall than the existing method.

We are surrounded by so many images these days. These images have their own meanings and have an effect on our subject, whether consciously or unconsciously. Michel Foucault disclosed that upon closer examination the rationalism deeply rooted in Western society was not made autonomously but involuntarily by heteronomous power. Because the emotion of image within this relationship can be effectively conveyed just through its being seen, the image has been used for controlling and mustering people through the adjustment of its meaning by power. With the advance of technology and media of today, the image in this visual power is out of the object for reproduction, and then forms a new paradigm of manipulation, transformation and reproduction and is being changed to the formation of Panopticon power and its corresponding relationship.

최근 소셜미디어 리뷰 데이터를 활용한 약물 이상 반응 탐지 연구가 활발히 진행되고 있지만, 약물을 복용하기 전 증상과 약물 이상 반응을 구분하지 못한다는 한계가 있다. 본 논문에서는 약물 이상 반응 탐지에서 약물 복용 전의 증상을 구분할 수 있는 Filtering Clinical BERT(FC-BERT) 모델을 제안하였다. FC-BERT 는 약물 복용 전 증상과 다른 약물에 대한 부작용 표현을 제거하기 위해 약물명이 나오기 전 모든 문장을 제거하는 필터링과 약물-부작용 쌍을 추출하는 모델을 사용했다. 성능 평가 실험을 위해 문장에 대한 ADE(Adverse Drug Event) 여부가 들어있는 ADE Corpus V2 데이터를 활용하였고 SPARK NLP 라이브러리에서 제공하는 ADE Pipeline 모델과 비교하여 성능 평가를 실시하였다. 실험 결과 필터링을 활용한 FC-BERT 모델이 기존 모델보다 정확도, 평균 정밀도, 평균 재현율, 평균 F1-score 가 모두 높은 결과를 보여주었다. 본 논문에서 제시한 모델은 기존 연구의 한계점을 보완하여 보다 정확한 약물 부작용 시그널을 탐지하는데 기여할 수 있을 것이다.

Detecting the status of websites, normal or phishing, is necessary to defend against intelligent phishing attacks. We propose a machine learning-based classification to predict the status of websites. First, we collect information about 'URL', convert it into numerical data, and remove outliers. Second, we apply VIF(Variance Inflation Factors) to understand the correlation and independence between variables. Finally, we develop a phishing website detection model with machine learning-based classifications, which predicts website status. In the test datasets, Random Forest showed the best performance, with precision of 93.74%, recall of 92.26%, and accuracy of 93.14%. In the future, we expect to apply our model to detect various phishing crimes.

Documentaries are being recreated into a new genre and the Web Documentary is the typical case. Web Documentaries are the documentaries those comprise creators and users and they are the novel type of text that the interaction with users is absolute. In this research, two Web Documentaries and are analyzed for examining how Web utilizes its features as expressive media inducing users to experience reality. Web Documentaries have dual and spatial structure that allows user interaction and make users to face with various information and knowledge about reality by its encyclopedic characteristics. Also, Web Documentaries give the role of progressing documentary and expanding text to users and that is, they stimulate users' consciousness reminding that they are the ones who explore through reality. In this process, users of Web Documentaries get potentiality of critically examining the reality suggested by documentaries and grasping the meanings beneath it. These features make Web Documentaries special contrast to traditional documentaries not only with their way of pursuing the reality but also with their meanings. This makes the innovative position of Web Documentaries phenomenon clear, issuing the necessity of the discussion about Web Documentaries more strongly. Web Documentaries are not just new media technological phenomenon, and they have their significance as a fundamental challenge toward traditional documentaries.

Space design in the 21st century has been developed in connection with media more various than ever. In the age of image represented by popular culture, space design connected with media is based on post-reason thoughts constituting the post-modern society, and reflects polysemously and pluralistically changes in the society through the identification of art with life. The movie, which is an image perceived particularly sensibly and the most impractical simulated image among various illusionary media images composing the contemporary society, is growing rapidly in interrelation with various fields of art based on its peculiar nature, and its influence is getting more extensive. The movie manipulates mass society to create what does not exist and restore lost images into new realities through the reproduction of extremely realistic senses, and uses them in establishing virtual realities and creating illusionary images representing the age of simularc. The illusionary expression of the movie produces new meanings through disintegrating existing meanings and recombining them, and expresses popular culture from a position closest to our everyday life. Such an analytical attitude toward the illusionary movie reflecting our society can be a new approach to space design. The present study attempts to suggest the possibility of applying such an illusionary characteristic of the movie as a methodology of space design by utilizing the characteristic as a conceptual language of space design.

With the recent advent of the New Normal era, realistic technologies and non-contact technologies are receiving social attention. However, the hair styling field focuses on the direction of the hair itself, individual movements, and modeling, focusing on hair simulation. In order to create an improved practice environment and demand of the times, this study proposed a non-contact hair styling VR system. In the theoretical review, we studied the existing cases of hair cut research. Existing haircut-related research tend to be mainly focused on force-based feedback. Research on the interactive haircut work in the virtual environment as addressed in this paper has not been done yet. VR controllers capable of finger tracking the movements necessary for beauty enable selection, cutting, and rotation of beauty tools, and built a non-contact collaboration environment. As a result, we conducted two experiments for interactive hair cutting in VR. First, it is a haircut operation for synchronization using finger tracking and holding hook animation. We made position correction for accurate motion. Second, it is a real-time interactive cutting operation in a multi-user virtual collaboration environment. This made it possible for instructors and learners to communicate with each other through VR HMD built-in microphones and Photon Voice in non-contact situations.

With the development of informational machinery and tools in the modern industrial society, the image is expressed diversely as tools of informational transmission and artistic communication. This image is revival equipment and transmissional media in which sound and light are comprehensively formed. The image's intuitive and sensational expressivity can revive subjects and express a fiction, a reality, a nonfiction, and a virtual reality as a communication tool that has synchronicity and the medium of meaning. Because of this, the domain of the image will be gradually extended in the future, and the world of cognizance that can be detected across our living space will absorb the image diversely and react. In this context, the investigator examined what influence image media and equipments have in space as spatial equipments, based on the recognition of cerrelation among the image, space, and mankind, namely, the environmental meaning the mage and the space contain. Therefore, this study was conducted from the aspects of relationship establishment between image equipments that are ever expansive to a variety of domains and the space that accommodates the equipments. As study findings, the influences the image equipments have on space and their expressional features are presented in three aspects: 'the expressional medium of mutual synergy','metaphysical ultra-epithelial space constituent',' and 'object'. This study seems to be meaningful in that we can expect the spatial approach method by purposes and spatial layout of image structures, with this study, through analyzing the meaning of relationship between image equipments and space.
