This study aims to examine online students' informal information seeking behavior during their loaming process and online loaming environments to support their informal information needs. The participants of the study were 29 online students in the Professional Development Studies of Rutgers University. Data was collected by the questionnaire and was analyzed with content analysis and descriptive statistics. This study focuses on when and why online students need human interaction to solve their learning problems and how they communicate with others to meet their informal information needs. Moreover, how online students think about their personal communication opportunities and the functions of their online learning system to support their loaming problems is also examined. Finally, online students suggest the ways to effectively support personal communication needed during learning process in online teaming systems. Based on the findings of this study, a few considerations are suggested in conclusions.

To come up with the recommendations to improve the patent & trademark retrieval efficiency, 100,016 patent & trademark search requests by 17,559 unique users over a period of 193 days were analyzed. By analyzing 2,202 multi-query sessions, where one user issuing two or more queries consecutively, we discovered a number of retrieval efficiency improvements clues. The session analysis result also led to suggestions for new system features to help users reformulating queries. The patent & trademark retrieval users were found to be similar to the typical web users in certain aspects especially in issuing short queries. However, we also found that the patent & trademark retrieval users used Boolean operators more than the typical web search users. By analyzing the multi-query sessions, we found that the users had five intentions in reformulating queries such as paraphrasing, specialization, generalization, alternation, and interruption, which were also used by the web search engine users.

This study is to research quintessence of information service in the libraries by interpreting 'Information' as it is ubiquitous. For the purpose, it investigates and analyzes information behaviors of the libraries in information-cultural history. The meaning of 'ubiquitous' is understood as a practice that everything we need should be inherent in our lives for its usefulness and effectiveness. Information is intrinsic in our lives and the libraries, information management systems, have been evolved by extending the intrinsic value of information, 'ubiquity'. Human being's history results from information behaviors and the meaning of the libraries consists of production, accumulation, organization and distribution of the libraries. It should be recognized that the ultimate purpose of the library services is for their users. Consequently information systems and technological networks in the libraries should be focused on applications and inherence for the purpose. Model studies of the libraries should be developed to user-centered information services that substantialize the interpretation of information, as it is ubiquitous. This study is a trial for defining the quintessence of the libraries. Furthermore, it provides foundation of understanding what the libraries are.

Analyzing out the Key Tasks and Developing the Professional Type of National Librarians through Job Analysis was made, because improving the professionalism of librarians is the strategy of survival in the competency based society. It is composed of 22 duties, 216 tasks of national librarian job and 96 key tasks is extracted among them. As the results, 12 types of professional librarian which is composed 10 function oriented types, and 2 user oriented types, is suggested: collection development librarian, cataloger taxonomist, information service librarian, reading coach, research librarian of international standards, database & system manager, international work librarian, national support librarian, marketing librarian, library literacy librarian, children' librarian, handicapped service librarian.

As the number of gates and basic events in fault trees increases, it becomes difficult to calculate the exact probability of the top event. In order to overcome this difficulty the BDD methodology can be used to calculate the exact top event probability for small and medium size fault trees in short time. Fault trees are converted to BDD by using CUDD library functions and a failure path search algorithm is proposed to calculate the exact top event probability. The backward search algorithm is more efficient than the forward one in finding failure paths and in the calculation of the top event probability. This backward search algorithm can reduce searching time in the identification of disjoint failure paths from BDD and can be considered as an effective tool to find the cut sets and the minimal cut sets for the given fault trees.

There are many studies reporting the average carbon dioxide levels in various indoor spaces. However, there have been a few studies showing how carbon dioxide concentration varied at many measurement points in one indoor space. In this study, the changes of indoor carbon dioxide concentration at classroom, library, and kindergarten were reported to find its carbon dioxide distribution change at various locations and altitudes. The maximum carbon dioxide concentration of the 3 sites were measured as 2,684, 2,295, and 1,526 ppm, respectively. These values exceeded the guideline concentration of 1,000 ppm for public places. The concentration of carbon dioxide was higher at upper area than lower area, and this is probably due to the rise of warm breathing air generated from students. In the upper area, the carbon dioxide concentration was higher at center area than four corners. However, in the lower area, the carbon dioxide concentration was higher at four corners than center area. Therefore, it could be concluded that the center of upper area is the best place for the installation of ventilation or carbon dioxide removal system.

This study suggested indispensable elements of metadata for electronic resource management and effectively manage of electronic resource in library. Therefore, this research analyzed into the data elements of DLF ERMI's ERMS data structure, foreign three universities. The Data elements are verified by domestic ERM specialist. As the result, trial categories are 12 elements, consortium categories are 15 elements, license categories are 33 elements, electronic resource information categories are 21 elements, access/administrative information categories are 20 elements, usage statistics categories are 13 elements, workflow categories are 14 elements, contact information categories are 18 elements.

The purpose of this study is to identify and systematize various facet elements required by users in fiction search situations from book tags to improve the fiction search environment. Based on the Ranganathan's PMEST formula, the basic facet system of the fiction was defined as 1) the personality that forms the fiction material, 2) the content and external characteristics that compose the fiction, 3) the reader interaction with books, 4) spatial information related to fiction and reading activities, and 5) time information related to fiction and reading activities. Out of approximately 310,000 tags assigned to 7,174 fiction, 3,730 core tags were selected and content-analyzed. As a result, various attributes were systematized around the top 25 categories of the fiction facets. The results of this study can be applied to facet navigation of OPAC and fiction DB in the future.

As the importance of the 4th industrial revolution and ICT technology increased, it became a software centered society. Existing software training was limited to the composition of the learning environment, and a lot of costs were incurred early. In order to solve these problems, a learning method using a web compiler was developed. The web compiler supports various software languages and shows compilation results to the user via the web. However, Web compilers that support artificial intelligence technology are missing. In this paper, we designed and implemented a tensor flow based web compiler, Google's artificial intelligence library. We implemented a system for learning artificial intelligence by building a meteorJS based web server, implementing tensor flow and tensor flow serving, Python Jupyter on a nodeJS based server. It is expected that it can be utilized as a tool for learning artificial intelligence in software centered society.
