In recent years, apartment finishing work items have increasingly become more upscale and diverse, and the kinds have increased in exponential numbers. A huge amount of information about finishing work items is produced and changed in the stages of planning finishing work item design and selecting alternatives in the early days of an apartment project. However, there are many problems raised by the poor information management of finishing work items. Thus this study suggested a cost-based information management system to manage information about finishing work items generated in the initial stage of an apartment project. In order to build the suggested system, the investigator designed an information management system based on the concepts and organization of system. And after setting a scenario of selecting finishing work items by conditions including the initial information values of finishing work items, information management for each alternative, and cost fix or free condition, I implemented and applied a prototype of an information management system for finishing work items among the participants including the project manager, interior designer, and builder.

In 21st century, tourism can's be formed without tourism information systems. Like other cities Kwangju Met. City has managed tourist information system though internet, but it provide tourist only with poor information as text datum and image datum. Therefore tourist can's get the effective and proper tourism information about Kwangju from that system. The purpose of this paper is to develop tourism information system on the basis of geographic information system for providing tourist with effective geographic tourism information. In the first place, spatial database on tourism information about Kwangju was built by 3 stage of areal scope: national scale, provincial scale and city scale. Next, by analyzing existing tourist information system, 4 major system function is developed: viewing tourism map, guiding tourism information, searching tourism information and printing tourism map. By complement of multimedia datum, this system shall be a major tourism resource of Kwangju.

This study firstly considered the changing processes of the 'guideline on dealing with restricted materials and information' which had been theoretical background for understanding the dealing situations of materials and information on North Korea. Additionally, this study investigated material possessions which were located in restricted-materials-dealing institutions affiliated with Ministry of Unification and Ministry of Education, Science and Technology, and also researched using results of the materials. Through the investigation analysis and precedent studies, problems caused by poor material using conditions were found and institutional developing plans were sought. In particular, this study suggested that 'the Interchange Council for North Korean Information and Materials' be constructed as a general management organization which controls many problems caused by using and treating materials and information on North Korea and cooperative models that can lead organic connection among all institutions for dealing with restricted materials and information.

This study examines the relationships between the adoption intention and ill results/"digital divide" of informatization. It is very important to enhance the ability to use the information around the country today. Government invested large sums in informatization. As a result, we became a leading country in the information and communication technologies (ICTs). But the speedy growth in information society enlarges the gab between 'information haves'and 'information have-nots', which results in decreasing the efficiency of informatization. Now, we have to consider the idea of "information welfare policy" to approach the problems of "information poor"which refers to those deprived of opportunities to access ICTS and use of the Internet. This paper shows that we can not reach the information welfare society without the solution of these problems, and which are obstacles to progress in informatization. It is hoped that the results from this study bridge and close so called "Digital Divide" within society and create the impartial information welfare society.e impartial information welfare society.

For the purpose of enhancing performances, many companies have tried to ensure the competitive advantages in ties with organization's strategy by putting effort in designing, developing and practicing the information system. Despite the information oriented small and medium enterprises (SME) being suffered from lack of funds, professional man-power and poor environment, fairly evaluating the level of information system within an organization can be a positive starting point for information oriented SME. Therefore in this study, for the purpose of using the SERVQUAL as a measurement tool provided by information system department under the environment of using information system, we try to free from the marketing oriented service category and develop models that are applicable in the information system environment to check reliability and validity. As a result, it is analyzed that enhancements of SERVQUAL simultaneously improves system and information quality which makes the employees satisfy with their working environments and sequentially affects to the collaborative performance of using information system.

Traffic information can be broadly categorized into point information and spatial information. Point information can be obtained by chocking only the presence of vehicles at prespecified points(small area), whereas spatial information can be obtained by monitoring large area of traffic scene. To obtain spatial information by image processing, we need to track vehicles in the whole area of traffic scene. Image detector system based on global tracking consists of video input, vehicle detection, vehicle tracking, and traffic information measurement. For video input, conventional approaches used auto iris which is very poor in adaptation for sudden brightness change. Conventional methods for background generation do not yield good results in intersections with heave traffic and most of the early studies measure only point information. In this paper, we propose user-controlled iris method to remedy the deficiency of auto iris and design flame difference-based background generation method which performs far better in complicated intersections. We also propose measurement method for spatial traffic information such as interval volume/lime/velocity, queue length, and turning/forward traffic flow. We obtain measurement accuracy of 95%∼100% when applying above mentioned new methods.

The 3rd Library Comprehensive Development Plan (2019-2023) of the Committee on Library and Information Policy under IFLA-UN 2030 Agenda emphasize the role of libraries in practicing social inclusion. At home and abroad, this is shedding new light on libraries as the public service institutions aimed at resolving information inequality. This study thus developed the information inequality measurement indicator optimized for libraries. For this purpose, FGI and Delphi technique were implemented as the verification stage of the expert group. As a result, the final indicators were derived in three evaluation areas, twelve evaluation items, and 30 evaluation indicators. Specifically, first, 3 evaluation items and 8 evaluation indicators were derived in the access evaluation area; second, 5 evaluation items and 12 evaluation indicators were derived in the competency evaluation area; and third, 4 evaluation items and 10 evaluation indicators were derived in the utilization evaluation area. This study is considered to be of great significance in that the information inequality measurement indicators optimized for libraries were developed, the first of its kind.

Information inequality has been differently conceptualized and defined in national laws. While the information inequality increases, library policy and informational service has lagged behind in meeting the needs of the society and the state. This paper aims to provide a preliminary research on information inequality, in terms of conceptualization, the legal base, terminology, index development based on the level of digital information. The paper also highlights cases on library services for solution of the difference. It compares library services designed for the disabled, ethnic minorities and the aged. The paper reviews the existing literature and project data. As a result, there are a number of processes and tasks that needs to be developed, including policy development, supporting organization, human capital, cooperating network, supporting facilities and service, and data.

The purposes of this study are to find the difference in information literacy among the elderly home care service users and to identify the impact of information literacy on service quality and satisfaction among service users. To achieve the goals, this study used 466 responses from the elderly home care service recipients in Jeollabukdo providence, and conducted t-tests, ANOVA and a series of regression analyses. The results showed that there were significant differences in information literacy by gender, household type, residence area, education level and subjective health status among service users. The study also found that service users information literacy had a significant impact on service quality and satisfaction, and it confirms the importance of customized service. This study suggests that information literacy inequality exists among the elderly home care service users, therefore, the way to improve information delivery strategy should be developed for the information-poor elderly.
