The purpose of this study is to raise the importance of information literacy programs for professional secretaries and to present guidelines for organizing them. While the level of projects in secretaries' information service is defined as an influencing factor to the necessity of information literacy programs, the level of scholarships or secretarial science as a major is not. An analysis on education needs of secretaries recommended that curriculum should be composed of 15 topics such as: meta search engines, special search engines, boolean operators, digital libraries, usenet, information centers, internet reference sources, SDI, topic search request, document delivery service, e-journals, commercial databases, fulltext service, search strategy and general search engines.

EBooks refer to electronic versions of books which are accessible via internet with forms of digital texts. In recent years, Amazon's Kindle digital eBooks has revealed the possibilities of success of the e-book market, which leads other companies to launch eBook service such as Google's eBook stores and Apple's iPad and eBook service. These reveal that the eBook market is finally showing a substantial amount of growth. Although the issue of technical support of eBook copyright protection emerges from the fast growing eBook marketplace, current technic of commercial DRM for protecting eBook copyright protection still has problems of non-comparability. Therefore, with the current technical status, DRM comparability problems, which have already occurred in music DRM environment, would also happen in eBook environment. This study suggests a standard framework to support eBook DRM comparability. When development of the standard reference software for eBook DRM comparability is completed, the sources will be registered as shareware to be open to public.

While variety of content on the internet has increased with the development of IT and person's needs about suitable information are increasing rapidly, studies for personalized service have been actively performed. In the study, we proposed the Hypertension and Diabetes risk analysis system according to personal food intake preference using the analysis method of buying preferences in product recommendation system. For the analysis of food intake preference, the Pearson correlation coefficient is used to calculate similarity weights between each reference analysis data and sample data and then reference data should be grouping into the similarity weights and calculating risk of hypertension and diabetes each group. To evaluate the significance of this system, 1,021 subjects are applied the system. Hypertension and diabetes groups' risk is significant higher than normal group statistically so, it is confirmed that food intake preference and the diseases were relevant. In this paper, we verify the validity of hypertension and diabetes risk analysis system using a personal food intake preference.

The purpose of this study is to investigate historical backgrounds, maintenance, revision and application areas of UDC(Universal Decimal Classification) in order to understand current issues of it systematically. Since 1905, n has been extensively developed and is now administered by UDC Consortium(UDCC). UDCC updates MRF(Master Reference File), an electronic form of the UDC schedules, once a year. UDC updates and publishes standard edition extended edition, and abridged edition according to the degrees of notion abridgement, and is available on the web. UDC can be now applicable to collection arrangement, SDI(Selective Dissemination of Information) service, searching subject bibliographies, switching language or subject gateway and metadata on the Internet, and automatic classification.

Internet users' desire to share shopping experiences has resulted in the appearance of the paradigm shift called social commerce, which combines social media with commerce. However, while foreign market realizes social commerce in a various way, current domestic social commerce market still seems to be highly filled with social shopping sites offering 50 percent discount, thus causing concerns about market distortion from a cutthroat competition. In order to overcome the limitations of social commerce remaining in the early stage, and to enhance the communication among consumers, this study conducted an empirical study on the social-commerce business models design based on context. The results of the study brought the imaginary, optimal combination model by conjoint analysis, using the segmented group through cluster analysis. To overcome the uniformity of social commerce and to enhance communication among consumers, the context-based optimal combination model should be proposed as the alternative social commerce business model in the domestic market which remains as a simple group-purchase function. Furthermore, this study will be used as an informative reference designing customer oriented service model for social commerce business.

Network-RTK GPS positioning technique based on national CORS(Continuous Operating Reference Station) and wireless internet access as like VRS and FKP was developed to overcome the limitations of traditional RTK technique. In Korea, NGII(National Geographic Information Institute) provides network-RTK service based on 51 CORS and mobile internet network. The purpose of this study is the accuracy evaluation of the height determined by GPS VRS technique based on network-RTK, So, in this study GPS VRS positioning was accomplished through 1st level BM line located at Sancheong~Jinju and $2^{nd}$ level BM line located at Geochang~Sancheong and the average error of the each BM line was calculated as 2.15cm and 1.80cm respectively. This result shows that GPS VRS height positioning can be used in $3^{rd}$ and 4th public BM leveling and also work regulation is needed to apply the GPS VRS height positioning.

With the rapid growth of mobile services, the various charging methods for mobile data have emerged in the mobile service market. Among them, network operators have begun to provide the zero-rating without any extra charge for the data that use the specific mobile application & services. Zero-rating, the free mobile data services by the network operators provoked many platform operators to confront business opportunity and risk. Though the platform operators are in urgent need of the strategy planning that considers business environments, any research endeavors explaining zero-rating and platform does not exist. Moreover, the analyses of potential effects of zero-rating on the business acts of platform operators has not been performed. Therefore, the study aims to identify the potential business opportunity and risk to prepare the various strategic countermeasure in platform operators' shoes. The study might enable the researchers to properly understand zero-rating and platform, and be utilized as a reference in planning the business strategy of the platform operators.

With the increased use of GPS in the field of various applications including surveying, the request for fast and precise positional information has increased. Several countries such as USA, Canada, and Australia have already been operating Internet-based automatic GPS data analysis system using e-mail and FTP. Expanding GPS market, it is necessary to establish automatic GPS baseline processing system that is accessible via Internet. The system developed in this study is operating on the web, and it allows the users to access easily regardless of time and place. The main processing engines are Bernese V5.0 and PAGES. They process user data with three GPS CORS(Continuously Operating Reference Station), and then send the report to the users through e-mail. This system allows users to process high accurate GPS data easily. It is expected that this system will be used for various GPS applications such as monitoring large-scale structures and providing spatial information services in private sector.

This study intendss to prepare specific support measures for cultural industry practioners and artists to respond to the development of artificial intelligence (AI) based on how they understand and accept AI. To this end, the acceptance attitude of practioners in the arts and cultural sectors toward AI technology was investigated based on the technology acceptance models and theories. The results show that, firstly, personal characteristics and service characteristics, which are influencing factors, have an effect on perceived usefulness, perceived ease of use, and intention to use AI services. Secondly, when there are perceived ease of use and perceived usefulness in AI services, innovative and effective personal characteristics reinforce the intention to use artificial intelligence services. It is expected that this study can be used as a reference for establishing policy measures to support cultural artists related to AI technology.
