The purpose of this study is to identify what are the common characteristics which enable the information management offices of research institutes to provide information services with their companies in effective ways, and furthur, in other to clarify what factors helf the improvement of effectiveness of information services. I have made on-the-spot investigations for the confirmation of present conditions of information service units of research institutes, their statistic data, and their managerial state. I have restricted my research to 36 information service units, as research targets, which are located in Changwon, Choongchong, and Kyongin areas as the reason mentioned in the introduction, and from their research data they keep, I have classified the top 10 information service units as Group A which show the most frequent use or application frequency of research data per a researcher, where as the lowerest 10 information service units are classified as Group B by the same evaluation of application frequency of their data. Then, the result of the comparision between Group A which provide high information services in effective ways and Group B which provide low information services with poor management leads me to identify the following characteristics in terms of the analyses of utilization of the data they process: 1. Those information service units in Group A have more volumes of books and information data, and annual increasing rates of books and informations are higher than those of Group B. 2. The regulations of book circulation in Group A are prescribed for the benefits of users, and if a long-term loan is not permitted, they are allowed to borrow more books at a time than in Group B. 3. The proportion of librarians to researchers is high, the librarians' career is long and their professional education background (the rate of librarians who majored in library science and information) is high In Group A. 4. Most of the directors of information service units are those who majored library science and information, and for the most part, librarians are promoted to the directors of information service units in Group A. 5. The information service units are managed directly under the directors of research institutes in their organization in Group A. 6. The information service units offer an education for information utilization to researchers as one of their managerial programs, and the contents of education are diverse, rich and informative in Group A. 7. The kinds of informations are various in Group A such as, SDI, prompt reports of contents of new informations, circulation of newly published publications, translation service, information analyses, critical reviews, etc. 8. The information service units in Group A have joined various cooperative systems which are aimed at cooperation, co-ownership of resources and informations. These findings lead me to argue that the hypothesis suggested in the introduction of this thesis has been proved without exception.

Purpose Domestic asset management fintech companies are expected to grow by leaps and bounds along with the implementation of the "Data bills." Contrary to the market fever, however, academic research is insufficient. Therefore, we want to analyze user reviews of asset management fintech companies that are expected to grow significantly in the future to derive strengths and complementary points of services that have been provided, and analyze key elements of asset management fintech companies. Design/methodology/approach To analyze large amounts of review text data, this study applied text mining techniques. Bank Salad and Toss, domestic asset management application services, were selected for the study. To get the data, app reviews were crawled in the online app store and preprocessed using natural language processing techniques. Topic Modeling and Aspect-Sentiment Analysis were used as analysis methods. Findings According to the analysis results, this study was able to derive the elements that asset management fintech companies should have. As a result of Topic Modeling, 7 topics were derived from Bank Salad and Toss respectively. As a result, topics related to function and usage and topics on stability and marketing were extracted. Sentiment Analysis showed that users responded positively to function-related topics, but negatively to usage-related topics and stability topics. Through this, we were able to extract the key elements needed for asset management fintech companies.

This study aimed at summarizing published study findings on the diagnostic value of rectal bleeding (RB) and informing clinical practice, preventive interventions and future research areas. We searched Medline and Embase for studies published by September 13, 2013 examining the risk of colorectal cancer in patients with RB using highly inclusive algorithms. Data for sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and positive predictive value (PPV) of RB were extracted by two researchers and analyzed applying Meta-Disc (version 1.4) and Stata (version 11.0). Methodological quality of studies was assessed according to QUADAS. A total of 38 studies containing 5,626 colorectal cancer patients and 73,174 participants with RB were included. The pooled sensitivity and specificity were 0.47 (95% CI: 0.45-0.48) and 0.96 (95% CI: 0.96-0.96) respectively. The overall PPVs ranged from 0.01 to 0.21 with a pooled value of 0.06 (95% CI: 0.05-0.08). Being over the age of 60 years, change in bowel habit, weight loss, anaemia, colorectal cancer among first-degree relatives and feeling of incomplete evacuation of rectum appeared to increase the predictive value of RB. Although RB greatly increases the probability of diagnosing colorectal cancer, it alone may not be sufficient for proposing further sophisticated investigations. However, given the high specificity, subjects without RB may be ruled out of further investigations. Future studies should focus on strategies using RB as an "alarm" symptom and finding additional indications to justify whether there is a need for further investigations.

Purpose: This study aimed to provide baseline data on the health care of children and the demand for visiting health care services in one region in efforts to support the implementation of visiting health care services for vulnerable children. Methods: Seventy-three children and their caregivers from the vulnerable social group and 82 children and their caregivers from the general group were selected as research participants. The data were collected through home visiting survey by professional nurses. Results: Children from the vulnerable social group were at higher risk of poor health care than the general group. Regarding home safety, vulnerable children were more likely to be exposed to unsafe conditions. With respect to nutrition, developmental play, developmental screening test, and home safety, visiting health care services were in demand for caretakers. Conclusion: These results indicate that to promote health care and safety conditions for vulnerable children, it is necessary to implement visiting health care programs that include the management of vaccination, medical check-up, growth and development, home safety, and nutrition. These findings can be used as the baseline data for the development of visiting health care programs for vulnerable children.

As data grows rapidly, the provision of appropriate information needed by individuals has become an area of new services, and customized services which is enabling the analysis of optimal services through collecting, storing, and analyzing personal data are emerging in many fields. However, due to the characteristics of customized services based on various information collected by customers during the use of the service, the problem of privacy infringement is raised at the same time, and many studies are being actively conducted to solve this problem. This study seeks to explore how the customer's in-depth and customized services has an impact on their customers, which has not been derived from quantitative research using the grounded theory methodology. Through this, 84 concepts, 33 subcategories, 13 Categories and paradigm models were derived. In addition, 'Understanding and acceptance of online behavioral advertising (OBA)' was derived as a core category, and finally, acceptance types of OBA were classified into 'positive acceptance type', 'indifferent type', 'calculating type', and 'active resistance type' based on the key categories. This study divides the acceptance types of online behavioral advertising through the emotions and behaviors of the consumers throughout the procedure of online behavioral advertising experiences. In addition to the statistical and quantitative information currently used for providing behavioral advertising, it provides new criteria to reflect the refinement of behavioral advertising and personal tendencies or characteristics.

Recently, with the proliferation of smart phones and mobile devices and the increase in the speed of mobile Internet, IT services are increasingly used in smart phones and mobile devices in a different way from the past. That is, a cloud service that downloads and uses data stored in the server in real time is expanding, and as a result, the security due to the continuous Internet connection of the user becomes a problem. In this study, we analyzed the relationship between factors affecting the continuous use of personal cloud service by using technology acceptance model. In addition to the technology acceptance model, confidentiality, privacy, accessibility, innovation, and self-efficacy were extracted from the existing research with emphasis on the characteristics of the cloud service and security factors. Moreover, the difference of intention to use among genders was verified through structural equation modeling with survey data from 262 personal cloud service users.

Game theory is adapted to a variety of domains such as economics, biology, engineering, political science, computer science, and philosophy in order to analyze economic behaviors. This research is an application of game theory to wireless communication. In particular, in terms of bargaining game we dealt with a multimedia resource allocation algorithm in wireless communication, which is rapidly spreading such as Wibro, WCDML, IPTV, etc. The algorithm is assumed to allocate multimedia resources to users who can choose and access differentiated media services. For this purpose, a utility function of users is devised to reflect quality of service (QoS) and price. We illustrated experimental results with synthesis data which were made to mimic real multimedia data, and analyzed differentiated service providing and the effect of the utility function.
