This study aims to analyze the current status of library automation systems and explore future directions for improvement. The study was conducted by surveying librarians at institutions participating in the KESLI and KCUE consortia to investigate the current status and satisfaction with library automation systems, and the current status and awareness of open source-based library automation systems. The study found that most automation systems currently in use in libraries were developed through outsourcing in the 2000s or 2010s, and that more than 50% of respondents were satisfied with the overall library automation system. Overall satisfaction was found to be influenced by satisfaction with the functionality, customer support services and construction and operational management of the system. Most current library automation systems are not based on open source software or cloud services, but the intention to use them in the future is high, with more than 40% of respondents saying they would use them within three years. This study is expected to serve as an important foundation for building an open source-based library automation system in the future.

Analysis systems and databases covering economics and industrial areas in Japan have long history, but due to considerable depth in specialty those have been used only by limited, certain patrons. It means that there are still few of practical system services at full scale. This paper describes the representative system services. Taking an example of interest prediction the author explains now to utilize systems and some points to be reminded. He also describes how to confirm newspaper information, how to predict economics, how to use various kinds of models based on economic prediction, and industrial analysis. Researches and studies are very often proceeded on economic prediction, and industrial analysis. Researches and studies are very often proceeded through interaction among researchers. So that we should make efforts continuously such as to rountinely get familiar with systems, to exchange information among users, to utilize helpdesks every time we need.

As circumstances of scholarly communication have been changed over time, there is a growing interest among academic institutions in collecting, preserving, and creating value-added services from digital contents being created by members of the academic community. The purpose of this study is to build an open access based Institutional Repository(IR) in the university for scholarly communication. For this study, this paper analyzes the example of, and makes a full range of process and implementation plan, and then suggests a realistic model of IR which is for dissertations/theses, academic journals, working papers, etc. The intellectual property right issues related to IR are also discussed.

It's getting popularized to collect information connecting web sites with massive information through the internet and advanced search engines. Users can handle digital materials like E-book wherever the internet is available and they will demand digital information increasingly. This study analyzes literature investigation, statistics analyses of the attached library of Kyushu University, drawings and field investigation to suggest a new model of a library which handles traditional paper-formed materials and digital-formed materials at one place with growing importance of digital materials. It results that a library performs a important role like a learning space and functions as a sociocultural communication space. Also it shows that it is required to basically reinvestigate the role of 'space' in the library with a great importance of digital materials. In the hybrid library combined with subjects and reorganized at one place, One-stop services like library materials and manpower can be provided for users staying at the same area.

The service sector comprises two thirds of world GDP in 2005 and takes 20% of the world trade. As the technologies such as telecommunication technologies advance, the long-distance trades in services is expected to increase. But there are few empirical research on the flows of services between regions. This paper studies the pattern of flows of long-distance trades in services across the regions. Since it is very hard to collect reliable data on long-distance trade in services, we collect data from regional input-output tables of Korea. The results shows that the hard service which can be consumed spatially separated from production tends to have more long-distance trade than the soft service which is consumed simultaneously with production. It also shows that regional gross domestic production is important factor for the pattern of trades in services.

Based on ontologies, semantic Web services enable the discovery, selection, and composition. OWL-S is a do facto standard ontology for describing semantics of Web services. Due to the difficulty of the OWL-S grammar, the teaming curve for constructing OWL-S description manually can be steep. This paper presents an efficient method for generating OWL-S descriptions from UML diagrams, which are widely used for software design and development. The proposed method is based on UML profiles to generate an OWL-S ontology from sequence or activity diagrams, which represent the behavior of a business process. Specifically, an XMI file extracted from UML diagrams is transformed into an OWL-S description via an XSLT script. Experimental results with a large volume of UML diagrams show that the proposed method deals with the control flow of complex processes and is superior to previous methods.

Concurrent with the more widespread usage of smart devices, mobile users' desires are becoming much more complex. Most IT experts insist that smart devices should have additional functions to satisfy these requirements. In particular, research has concentrated on LBS (Locationbased Service), because it is considered one of the most common mobile service types. Generally, Wi-Fi has a critical limitation for use for LBS services, because it requires new network connection points whenever its location (Network Zone) changes. Unfortunately, GPS also has a systematic problem in providing LBS service in the indoor environment, because of its inaccuracy in processing data. So, to redress these limitations, iBeacon technology has been designed, and is currently used for LBS service instead of Wi-Fi or GPS. By using iBeacon, which is based on Bluetooth 4.0 LE technology, we propose a M-SAS (Mobile-Subway-Alarm-Service System) that could accurately and timely provide its users with various mLBS (micro LBS) services, such as current user location, and subway arrival time.

대용량 데이터의 분산/병렬 가시화를 위해서는 가시화 클라이언트와 서버 사이의 프로토콜이 필요하다. 기존 가시화 도구들은 개발 도구에 특화된 프로토콜을 사용하고 있으며, 이 때문에 클라이언트와 서버는 매우 tightly-coupled 되어 있다. 본 논문에서는 응용에 독립적인 분산/병렬 가시화를 위한 가시화 프로토콜을 설계하고 구현한다. 또한, 시변환 데이터의 효율적 가시화를 위해 animation을 구현할 수 있는 프리미티브를 설계하고 status machine으로 병렬 전송된 데이터들 간의 동기화를 구현한다. 이러한 응용 독립적 가시화 프로토콜을 도입함으로써 가시화는 병렬 분산 가시화를 수행하는 그리드의 서비스나 슈퍼컴퓨팅의 서비스로 확장될 수 있을 것이다.
