The number of youth smartphone users has been increasing, and they use smartphone applications to satisfy their various types of information needs. Nevertheless, few researchers have addressed youth information behavior on applications. In this study, the author examined the application use behavior of youth in response to their work- and everyday life- information needs. The author collected 114 completed questionnaires from students enrolled in a middle school and a high school. The survey results show that participants' usage and perception of smartphone applications were high, and they were using information, entertainment, and communication applications to meet their information needs. In particular, their preference for application use differed by the type of information needs. Also, participants were considering cost, easiness, privacy policy, review, information quality, providers, interface design, and recommendation to choose applications. This study confirms the role of smartphone applications as an influential information source, and it also provides useful implications for educators and for application developers.

This study examines the design and utilization of video storyboard surrogates in the digital video libraries. To do this, first we constructed the arrangement model of key-frames for storyboard based on the FRBR model, image communication and PRECIS Indexing theories and evaluated the model using 6 sample videos and 26 participants. The study results show that the video storyboard surrogates based on the arrangement model has a higher accuracy value in terms of summary extraction than that of the sequential video storyboard. Moreover, watching both types of video storyboard one after another, especially browsing the sequential video storyboard first and then the arrangement model-based one, produces a remarkable increase in accuracy value of summary extraction. The study proposes two methods of utilizing the video storyboard surrogates in the digital video libraries: Designing a video browsing interface where users can use the sequential storyboard as a default and then the arrangement model-based one for re-watching; and utilizing the arrangement model-based storyboard as structured match sources of image-based queries.

The National Archives of Korea(NAK) has arranged and operated 'Guidelines on Operating Copyright for Archives' and 'Regulations on Operating Reference Room' to protect the copyright for archives. However, the Guidelines and the Regulations only provide application to the Copyright Act and principles on internal managing copyright without presenting copyright issues for each type of archives. Therefore, additional detailed guidelines have to be arranged for the users to access to copyright issues easily by presenting them the standards of judgement or principles on copyright issues for each type of the archives to facilitate the use of archives collected already. We also need to define the details on Copyright Act and Moral Rights Act to collect archives. This study is an prior analysis for that purpose. Lively discussion and way of operation in an aspect of the copyright in relation to private records should be sought in the future.

Organizational communication is an element of organizational structure formation; it is also a process of achieving organizational goals through the information sharing among the staff members in the organization as a social system. Organizational performance is a multidimensional concept composed of efficiency and effectiveness and satisfaction. Effectiveness implies service quality and the degree of goal achievement. Service quality by using the $LibQUAL+^{TM}$ model can be considered as an objective performance measure for libraries. This study aims to identify the effect of organizational communication in public libraries on service quality as a performance measure using the $LibQUAL+^{TM}$ model through statistical analyses of the results from questionnaire surveys of librarieans and users in 8 public libraries in Seoul metropolitan area. The result says the characteristics of organizational communication(upward, horizontal, downward communication) affects the three elements in the library service quality, such as affect of service, information control and library as place.

In this paper chemical process plant information is addressed to be standardized. The chemical process plant information has complexities in the context of its various types such as functions, shapes, connectivity etc. as well as its usages such as design, construction, operation, maintenance and so on. It was well known that the standard should be made by its users themselves to be used widely. The chemical process industry oriented ISO 15926 RDL (Systems and integration of life-cycle data for oil and gas production facilities : Reference Data Library) can provide the methodology for exchanging and sharing of plant equipment information, which will be developed through integrating existing standards such as ISO 10303 AP221, AP231, AP227. The PCA (Posc Caesar Association) which is located in Oslo, Norway, has the initiative in developing ISO 15926. Korea is a member of PCA and takes part in proposing and reviewing the new standard. The trends and prospects for the standard of chemical process plant information are addressed.

Video abstraction is a process to pick up some important shots on a video, while the important shots might vary on the persons subjectivity. Previous works on video abstraction use only one low level feature to choose an important shot. This thesis proposes an abstraction scheme that selects a set of shots which simultaneously satisfies the desired features(or objective functions) of a good abstraction. Since the complexity of the computation to find a set of shots which maximizes the sum of object function values is $0({2^n})$, the proposed .scheme uses a simulated annealing based searching method to find the suboptimal value within a short period of time. Upon the experimental results on various videos, we could argue that the proposed abstraction scheme could produce a reasonable video abstraction. The proposed abstraction scheme used to build a digital video library.

In this paper, we have studied the technical contribution of internet as a computer mediated communication(CMC) tool for collection management. A new communication process is appearing due to the development of information technology and telecommunications technology which enable users to have an access to information without the help of librarian. Also, internet makes collection management possible in the absence of vendors. This study found out that internet reinforces the traditional functions of collection management and enables librarians to better perform their roles. The future library manager should become actively involved in the development of technology in order to manage resources of internet focusing on the needs of user. Also, we have concluded that collection management should be modernized and transformed with its emphasis on the new evaluation method and assessment of quality when offering resources of internet in the communication process using computers.

The interface design for most present query-base model of OPAC systems does not include the function to implement an iterative feedback process till the user arrives at satisfied search results through the interaction with the system. Also, the interface doesn't provide the help function for a user to select pertinent search terms. To formulate a query at the present OPAC system, a user should learn a set of syntax different from system to system. All of above mentioned things make an end-user feel difficult to utilize an OPAC system effectively. This experimental system is attempted to alleviate a few limitations of the present OPAC system by a n.0, pplying the direct-manipulation technique as well as the feedback principle. First, this system makes it unnecessary for a user to learn some syntax for query formulation by providing option buttons for access points. Second, this system makes it possible for a user to decide whether each displayed record is relevant or not, and for keywords included in the relevant records to be automatically stored in order to be used for later feedback. Third, in this system, the keywords stored in [sayongja yongeu bogyanham] can be deleted if unnecessary or can selected as search terms for a query expansion as well as a query modification. Fourth, in this system, after inputting the original query, the feedback process can be proceed without coming back to the previous search step until a user becomes satisfied with the search results. In conclusion, the searching behaviors of heterogeneous users should be continuously observed, analysed, and studied, the findings of which should be integrated into the design for the interface of the OPAC system.

This is an exploratory study targeting initial users to evaluate the usability of an aggregator-supplied full-text database and to analyze the differences in task performance and perceptions based on participant characteristics. The differences in completion time and perceptions on ease of use, terminology, subject categories and satisfaction were analyzed based on the participant characteristics such as Kolb learning style, gender and participation in user instruction on full-text databases. The results indicated that there was a statistically significant difference in completion time based on the Kolb learning style. Also a statistically significant difference was found in perceptions on ease of use and terminology based on gender. However no statistically significant difference was found in perceptions on the usability of the database based on the participation in user instruction.
