The purpose of this study was to find the characteristics of the exhibition space planning methodology as 'Spatialization of Knowledge' through analyzation of the spatial structure in the contemporary museum architecture. The result of this study is expected to apply in designing an exhibition space and may become a target point. Further more this study can result a museum design to assist actual museum to fully function and play a role as a service facility for users by containing broad knowledge and fair understanding of user's needs in museum planning. Basic survey of museum architecture history will help visualizing conceptual structure of the museum exhibition and the 'Space Syntax' method has been used to make this conceptual data more objective. This study found that the contemporary museums most likely to include in its planning the various spatial organization in order to convey knowledge. The result reflects the needs of modern society which shows the design accepting individuality in society with variety of needs. And this also explains that museum space organization has to reflect various ways or methods of conveying knowledge. In addition, users have tendency to prefer more open space organization for easy access and approach in exhibition environment. It is clear to see the change in today's viewing pattern that the users prefer flexible exhibition space where they can be more proactive in receiving knowledge by following their own circulation over architecturally constrained circulation pattern within the exhibition area.

The relationship between users and physical elements of environmental gives a space special characteristics. The Environment Probabilitism by Altman shows that behavior and environment, both response, effect each other construct their characteristics. People can choose their response consciously or unconsciously during their walking , sitting, standing, talking in their environment. Designing a good place can lead people to the goal that they want and designer intend to get, A good place well designed as an positive place is organised with 3 points(1) User's behavior (2) physical elements in environment (3) meanings produced between behavior and physical elements. In this study the importance of physical elements are focused on. In the place where we can have permeability, variety , legibility, robutness, visual appropriateness, richness, personalisation physically , these characteristics will encourage people to have strong motivation and to choose the most active way . From this perspective the circulation of physically handicapped persons is analyzed into their behavioral environment and their behavioral response. The analysis shows the handicapped in our situation has no environmental right for a man itself ,even they have no street to walk safely. And their response to the environment was very negative. Basically the elements from exterior space to interior space should be guaranteed for everyday according to their behavioral characteristics include handicapped. From this study the result shows that the needs of a person should be considered and accepted as an important design problem for improvement our environment.

본 논문은 국내 대학도서관 학술연구정보 이용자들을 그들의 정보요구, 정보이용행태, 정보활용능력을 중심으로 살펴보았다. 이용자들은 도서관 이용에 관한 기본적인 안내정보를 가장 많이 필요로 하고 있으나 대학의 온라인이나 오프라인 도서관시스템은 기본정보제공이 불충분한 것으로 나타났다. 또한 이용자들은 학술연구정보에 대한 주제탐색의 요구를 가지고 있으나 이를 만족시킬 만한 탐색지식이나 정보원에 관한 정보가 부족한 상태인 것으로 드러났다. 이용자의 학술연구정보 활용능력은 저조한 편이며 특히 기사검색이나 원문검색과 같은 고급학술연구정보 활용능력은 극히 낮은 수준에 머물렀다. 대학도서관의 안내정보시스템과 사용자 인터페이스의 개선이 요망되며 피상적인 이용자교육을 지양한 고급의 학술연구정보를 활용할 수 있는 이용자교육이 요청된다.

This study is aimed to examine the characteristics of library space, in which user experiences and social networking are central in its design. Today, a library is a place to provide diverse accesses and experiences to information networks, where various individuals and user groups come and share mutual understanding and experiences. Library users developed social ties and a sense of community through library experiences. As a multipurpose space of a community, a library has the characteristics of urban public space like sidewalks and plazas. The eight case studies of libraries are analyzed from the viewpoint of each factor of library experience, including landscape, sidewalk, and plaza experience. The study drew its conclusions as follows. First, a library is a regional landmark for the users. Thus, it tends to be designed to allow transparency on its surface which introduces inner and outer landscape into the inside of the building. Second, the users experience a library similarly as they experience an urban street where they interface, browse, and interact with people and information. As they interact and share experiences, they develop solidarity and social ties among them. A library is designed to preserve continuity to adjacent streets, which increases accessibility to the building and hosts street activities into the building. Third, a library today is designed to be a flexible open space with information networking as well as community networking which allows library users diverse activities within it. For example, a multipurpose grand stairs in the middle of the main circulation of a building allows the users diverse activities. A large open stack with reading areas gives the users the feeling of an urban plaza where they can move vertically and horizontally. In conclusion, all findings of this study imply a user-oriented design for a library building.

Detection of fake news is a complex and a challenging task. Generation of fake news is very hard to stop, only steps to control its circulation may help in minimizing its impacts. Humans tend to believe in misleading false information. Researcher started with social media sites to categorize in terms of real or fake news. False information misleads any individual or an organization that may cause of big failure and any financial loss. Automatic system for detection of false information circulating on social media is an emerging area of research. It is gaining attention of both industry and academia since US presidential elections 2016. Fake news has negative and severe effects on individuals and organizations elongating its hostile effects on the society. Prediction of fake news in timely manner is important. This research focuses on detection of fake news spreaders. In this context, overall, 6 models are developed during this research, trained and tested with dataset of PAN 2020. Four approaches N-gram based; user statistics-based models are trained with different values of hyper parameters. Extensive grid search with cross validation is applied in each machine learning model. In N-gram based models, out of numerous machine learning models this research focused on better results yielding algorithms, assessed by deep reading of state-of-the-art related work in the field. For better accuracy, author aimed at developing models using Random Forest, Logistic Regression, SVM, and XGBoost. All four machine learning algorithms were trained with cross validated grid search hyper parameters. Advantages of this research over previous work is user statistics-based model and then ensemble learning model. Which were designed in a way to help classifying Twitter users as fake news spreader or not with highest reliability. User statistical model used 17 features, on the basis of which it categorized a Twitter user as malicious. New dataset based on predictions of machine learning models was constructed. And then Three techniques of simple mean, logistic regression and random forest in combination with ensemble model is applied. Logistic regression combined in ensemble model gave best training and testing results, achieving an accuracy of 72%.
