The aim of this paper was to determine the utilization of online information resources by undergraduate students in the University of Nigeria, Nsukka. It was undertaken specifically with the objectives of identifying the online information resources used; academic purposes for their use, extent, problems and strategies for improving the academic use of the resources by undergraduate students. Descriptive survey was used as the research design. The population of this study comprises of all 25,657 regular registered undergraduate students in University of Nigeria, Nsukka. The sample for this study comprises 2500 students which is 10% of the population. The results of the study shows that most of the online information resources are not used by the undergraduate students. Just a few of them are highly used. Some of the academic purposes for the use of the resources include to do course assignment and project works and to stay up-to-date on social events. The major problems responsible for the low utilisation of the resources include incessant power failure, limited available computers in the university library, and server's low bandwidth. Based on the findings, maintenance of uninterrupted power supply, provision of enough computers in the library; constant upgrade of server's bandwidth and many more were recommended as the strategies for improving the use of online information resources by undergraduate students in UNN. The implication of this study lies in the fact that solutions to the problems raised would be helpful to the university management, librarians and students in ensuring maximum and adequate provision and effective utilisation of online information a resources in the library.

The study on Wholesale pricing of MVNO using two way interconnection charge system is rare. This paper considers MVNO possessing its own facilities and subscribers. While previous studies focus on wholesale provision by MNO, this paper employs another approach from existing MVNO model. This paper introduces two way interconnection charge system by recognizing that mobile network interconnection is important to complete the call from MNO to MVNO as well as the call from MVNO to MNO. Also it is interesting to analyze wholesale pricing when there is brand loyalty between MNO and MVNO. This paper analyzes retail pricing and wholesale pricing under duopoly competition and drives social optimal solutions using linear city model.

Purpose: Pain perception is affected by a wide range of contributing factors, including biological, psychological, and social factors. Although the provision of visual information could have a modulatory effect on pain perception, it is unclear whether such a visual effect might vary depending on the anatomical site and stimulation type. This study aimed to analyze the modulatory effect of visual information on the perception of sharp and dull pain in the face and hand and to assess the influence of individual fear levels on modulatory visual information. Methods: A total of 68 healthy male and female volunteers were recruited for this study. Pressure and pricking pain with and without visual information were induced on the masseter and thenar muscles, and alterations in pain threshold were evaluated. The survey was conducted using the Geop-Pain Questionnaire (GPQ). Results: The pricking pain threshold of the hand was significantly elevated when viewing the stimulated hand. This result indicated that the provision of visual information could decrease sensitivity to sharp pain in the hand. However, when correlating the GPQ score with the alteration in thresholds induced by visual information, no significant correlation was observed between the GPQ score and the threshold difference induced by visual information. This finding showed that the visual effect was not significantly affected by the fear level. Conclusions: This study showed that the effect of visual information on the pain threshold could vary according to the anatomical site and stimulation type. A better understanding of such a modulatory effect on pain perception might be useful for clinicians during painful therapeutic procedures.

본 연구는 SNS채널속성에 따라 검색의도가 구매행동에 미치는 관계를 분석하고자 SNS채널을 최근 1년 이내에 상품을 구매한 사용자를 대상으로 하여 구매행동을 설문조사하였다. 이를 바탕으로 분석한 연구결과는 SNS채널속성에서 정보제공성과 정보상호작용성은 검색의도에 영향을 주는 것으로 분석되었다. 그러나 정보의 신뢰성은 검색의도에 유의적인 영향을 주지 않는 것으로 분석되었다. SNS채널의 이용자를 통해 구매행동을 높이기 위해서는 정보신뢰성과 정보제공성도 주요시되고 있으나 그 보다도 더 중요한 것은 SNS채널 검색의도라고 볼 수 있다. 검색의도는 정보신뢰성과 정보제공성을 높이는 조절효과를 함으로 단순히 SNS채널의 속성을 높이는데 이어 정보제공성과 정보상호작용을 높여 검색의도를 높이는 것도 중요하다고 볼 수 있다.

Purpose: The purpose of the study is to identify the influence of the hospital mobile app service quality on consumer satisfaction, involvement, and re-use intention of consumers who have experience in hospital mobile app service. Methodology: The survey was conducted on 230 users. The collected data were analyzed using correlation analysis, multiple regression analysis, and the Process Model in Hayes(2013). Findings: (1)The usability, reliability, and medical information provision among the service quality factors of hospital mobile apps had an effect on reuse intention, and consumer satisfaction partially mediated. (2)The usability and the provision of medical information were partially mediated by the involvement, which also affected the intention to reuse. (3)Only reliability showed an age-moderated effect. In reliability and re-use intent, age was a moderated mediating effect that controlled the effect of consumer satisfaction. Practical Implications: The results of this study provide initial data of mobile app services centered on hospitals and prove the type of consumer usage. It suggests that it can be used to attract potential consumers of hospitals and strategies to increase the use of mobile apps.

This study comprehensively draws a conclusion using factors of economic, social, and educational value and performed a survey on librarians and users to compare and analyze the difference in perception between the two groups. The result are as follows: First, Libraries had the social value not only on research and personal learning but also on establishment and vitalization of communities, provision of opportunities to share ideas between local residents and create something new, and provision of recreation to improve the residents' capability. Second, both groups evaluated the libraries' educational role and function relatively highly. In particular, the librarians scored very high for the items that the libraries' educational role was expanding, the libraries were a part of the educational system, and the libraries' value on reading and literacy was great, and the users thought that libraries had an value because they were a part of education and the educational system. Third, economic value part also obtained relatively lower scores than other values; the mean of the librarian group was 3.46 and the user group was 3.43. Among the economic values, the librarian group scored the highest for the area of economic value for local communities, and the greatest scores were given to manpower development by the users.

Are the benefits derived from ICT based reference and information service worth the financial and other commitments devoted to it? In an attempt to answer this, this study delved into finding out the perceived benefits; the rational for ICT based reference services in Nigerian university libraries. The main objectives were to find out the purposes for using ICT facilities in reference services delivery and the perceived benefits derived from using ICT resources in reference and information services. Being a survey, questionnaire was used to collect data from the librarians of twelve (12) universities; two (2) each sampled from the six geopolitical zones of Nigeria. Data was analyzed using frequencies, mean scores and standard deviations. ANOVA statistical analysis was used to test the hypothesis of no significance difference in the benefits derived from ICT based reference services using p-value of 0.05 to calculate the level of significance. Findings showed that librarians and library users made use of ICT facilities for different reference purposes especially to obtain information they need using the internet. Other reference needs for which patrons used the ICT facilities included: - access to current e-books and e - journals, user education and access to global information in other libraries. Provision of current awareness services (CAS) and selective dissemination of information services (SDI), on-line searching using workstations in the library, provision of on-line public access catalogue (OPAC) services, keeping statistics of users of the reference section and compilation of bibliographies. Further findings showed that the librarians and library users derive a lot of benefits from their use of ICT facilities in reference services. The results showed that easy retrieval and dissemination of information to patrons were ranked highest by the librarians amongst others.
