This study was carried out aiming to provide information and enhance the satisfaction of real-time smartphones users on Rural Amenity Resources Information Services. For this purpose, domestic and international discussions and surveys on technology developments and expert analysis smartphone technology were reviewed. And empirical data were collected from 600 people through structured questionnaires including smart-phone experience, smartphone usage behavior, the required content, service items, service quality, Through this information, the content of rural amenity resources, how to take advantage of smart phones. Service Plan and developed, and a rural village locations to target mobile phone technology, the content was established. Through the preference analysis of the collected data, we designed the contents of rural amenity resources information based on smart-phone. It will be helpful to enhance the interchange between urban and rural such as farmer's market and rural tourism.

The national R&D information of ministries which define shared information related to national R&D projects has been derived. Among them, 21 percent are code items which can provide important standards to classify information and put out S&T statistics. Therefore, it is necessary to standardize the code items that are differently defined and managed by each research management specialized organization. For this, the National Science & Technology Information System(NTIS) intends to provide a clear code standard for the national R&D information of ministries by defining the NTIS Standard Code. In this study, we also describe the classification service to manage the NTIS Standard Code, National Standard Science and Technology Classification Codes which have been used for national R&D projects's survey and analysis as a unified way.

Content Delivery Networks (CDN) server loads that fluctuant necessitate CDN to improve its service scalability especially when the peak load exceeds its service capacity. The peer assisted scheme is widely used in improving CDN scalability. However, CDN operators do not want to lose profit by overusing it, which may lead to the CDN resource utilization reduced. Therefore, improving CDN scalability moderately and guarantying CDN resource utilization maximized is necessary. However, when and how to use the peer-assisted scheme to achieve such improvement remains a great challenge. In this paper, we propose a new method called Dynamic Moderate Peer-assisted Method (DMPM), which uses time series analysis to predict and decide when and how many server loads needs to offload. A novel peer-assisted mechanism based on the prediction designed, which can maximize the profit of the CDN operators without influencing scalability. Extensive evaluations based on an actual CDN load traces have shown the effectiveness of DMPM.

Each country has tried to collect and utilize sci-tech information which is the critical factor for the technology innovation of the nation. The national science and technology information center has the main role for finding, acquiring, and utilizing S&T information scattered all over the world. Korea Institute of Science and Technology Information delivers almost 300,000 articles to the users every year. As the quantity of information increases rapidly, its source, its storage media and its delivery method become diverse. This study analyzes the user satisfaction on S&T document delivery service of the national information service center generally. The ultimate aim of this study is to improve the quality of the document delivery service and meet the users' requests in the changeable information circumstance.

국가과학기술종합정보서비스(NTIS: National Science & Technology Information Service)는 국가R&D 사업정보를 한 곳에서 서비스하는 국가R&D 지식포털이다. NTIS의 효율적 기획 및 업무운영 총괄을 위하여 NTIS 표준운영절차(SOP: Standard Operating Procedures) 수립의 필요성이 증대되었다. 본 연구에서는 본 연구에서는 선진이론 모델 및 국내사례를 분석하고, NTIS 구축에 참여한 내부의 환경적 요건과 운용체계 요구사항을 고려하여, NTIS 운용체계에 가장 실무적으로 적합한 NTIS SOP를 수립하였다. 이와 더불어 NTIS 운영주체간 NTIS SOP 정보의 효율적 공유를 위하여 NTIS SOP 공유시스템을 구축함으로써, 업무별 권한별로 NTIS SOP를 공유하고 활용할 수 있도록 하였다.

In modern society, there are WEB sites that provides information in various fields by many advances in IT technology. As the number of users accessing the Web increases, one server becomes unavailable, and multiple servers are deployed to provide the service. In addition, systems that control servers are required to manage multiple servers. However, server control systems in the existing market are mostly those that notify managers through SMS and apps when a server's down or a controlled port is closed. However, in case of servers that generate a lot of traffic, the Web server and the WAS are operated and managed each independently. The WEB and WAS provide service by connecting to each other. However, the connection between WEB and WAS may be disconnected due to various environmental factors. In this case, the existing control system can not determine whether the service is working properly. Even in the case of WEB and WAS of a server that is operated independently, there is a phenomenon that the existing control system does not know the problem even when the normal service is not provided due to environmental factors such as disconnection to DB. In this paper, we implemented a system to check the normal state of Web service using Web crawling to solve this problem.

The advent of the internet has caused a number of changes in production and dissemination of science and technology information(STI). STI was mainly produced in the form of publication before the advent of the internet. The popularization of the internet, however, has induced the mass production and distribution of STI through the internet. In consequence, the importance and usefulness of on-line STI have become on a level with those of published STI. The rapid growth of quantity and quality of on-line STI forces information service organizations try their best for improving the service satisfaction. In an effort to improve the satisfaction, researchers on information management examined the classification of information resources by exploring the counterparts of bibliography and/or web information service. We examined the national standard of the classification related to science and technology and proposed a practical scheme for the classification of on-line STI resources.

Mobile devices are the most important equipment for accessing various kinds of services. These services are accessed using wireless signals, the same used for mobile calls. Today mobile services provide a fast and excellent way to access all kinds of information via mobile phones. Mobile service providers are interested to know the access behavior pattern of the users from different locations at different timings. In this paper, we have introduced an associated tree for analyzing user behavior patterns while moving from one location to another. We have used four different parameters, namely user, location, dwell time, and services. These parameters provide stronger frequent accessing patterns by matching joins. These generated patterns are valuable for improving web services, recommending new services, and predicting useful services for individuals or groups of users. In addition, an experimental evaluation has been conducted on simulated data. Finally, performance of the proposed approach has been measured in terms of efficiency and scalability. The proposed approach produces excellent results.

Large amounts of research results are being produced with the rapid growth of science and technology. The current method for constructing the database was way too time and cost consuming. In the currently upcoming technology and knowledge society, web service is required to provide the various professional service for national R&D reports. A process to manufacture E-Book for professional service is also required. This research shows the conversion models with efficient manufacturing process and the systems related to the development through defining the National R&D reports.
