The introduction of new technologies has had a significant influence on teaching, learning and research activities in universities. This has offered university libraries opportunities to provide information resources in a variety of formats. This study investigated the influence of information literacy skills on postgraduate students’ use of electronic resources in private university libraries in Nigeria. The study adopted the survey research design. The study population comprised 2805 postgraduate students in five private universities offering postgraduate programmes in South-West, Nigeria. Multistage sampling technique was used in the selection process. A purposive selection of four faculties from each of the five universities was carried out. Proportionate sampling technique was used to select the sample size of 550 postgraduate students as the respondents for the study. Findings revealed that there was a significant positive correlation between information literacy skills and use of electronic resources (r = 0.28, p < 0.05). The study concluded that the utilization of electronic resources promoted access to current information among postgraduate students in the selected private universities in South-West, Nigeria. The study recommended that the management of private university libraries should ensure a continuous provision of electronic resources with adequate information communication technology tools to facilitate their use. 展开更多

Since land resource database development in 1987/1988, a large amount of digital data in spatial, tabular and metadata format has been collected and generated. There are some application softwares of soil database to manage such a large amount of data, i.e.: Side & Horizon (SHDE4), Soil Sample Analysis (SSA), and Land Unit in dbf file, while Site and Horizon is in DataEase formats. The database contains soil physics and chemical property data of each soil horizon from surface to effective soil depth, climate, land surface condi- tions, and other parameters required for soil classification. Currently, database management software for land resources is still based on DOS and is stand alone. The system is not efficient and effectively used as Agri- cultural Land Resource Information System. At present, as a key component of this system requires review and development of new database software is compatible with the development of information technology. This paper explains about development of interactive agricultural land resources information system for op- timizing land resources data utilization. Hopefully, the software can give contributions in national Agricul- tural Land Resources System Information development for supporting food security. 展开更多

In taking into full consideration of the technology acceptance model(TAM),this empirical study has made a few assumptions and also has formulated a model for the study on the level of satisfaction of database users. This research project was conducted by collecting relevant data from library users of five universities. Specifically, it aimed to measure database users' level of satisfaction and tried to find factors affecting these graduate students who are using databases regularly at their university libraries. An analysis of the collected data shows that the level of database users' satisfaction could be directly affected by the database service quality, the easiness of accessing the system and user perceived notion of usefulness of those databases that they use often. This study also found that database users' gender could be a significant factor in their perceived notion of easiness of accessing databases, and also in their perceived notion of satisfaction for their successful information retrieval operations. The frequency of accessing databases by these graduate students has an impact on users' perceived notion of easiness of database access. The users' school classifications could make a significant difference in their perceived notion on the extent of usefulness of a particular database. 展开更多

A mobile medical information system (MMIS) is an integrated application (app) of traditional hospital information systems (HIS) which comprise a picture archiving and communications system (PACS), laboratory information system (LIS), pharmaceutical management information system (PMIS), radiology information system (RIS), and nursing information system (NIS). A dynamic resource allocation table is critical for optimizing the performance to the mobile system, including the doctors, nurses, or other relevant health workers. We have designed a smart dynamic resource allocation model by using the C4.5 algorithm and cumulative distribution for optimizing the weight of resource allocated for the five major attributes in a cooperation communications system. Weka is used in this study. The class of concept is the performance of the app, optimal or suboptimal. Three generations of optimization of the weight in accordance with the optimizing rate are shown. 展开更多

The first part of the article provides an overview of the theoretical evidence, the main provisions, and the implementation strategy of information support for bioresource and ecosystem research in the north-west Pacific, which has been conducted over the past 20 years in the Russian Far East Research Institute TINRO-Center. In short, the concept consists of a combination of the following four assertions: 1) For the steady and sustainable development of the Russian Far East, the entire Russian Federation and the Asia-Pacific Region in general, environmental, food, economic, and other security is required, which cannot be achieved without the rational use of bioresources based on the ecosystem approach to the management of aquatic bioresources. 2) For the inventory, appraisal, monitoring, forecasting of the state of and management the natural water resources when applying this approach, statistically relevant quantitative information is required on the greatest possible number of constituents of marine biocenosis of the north-western Pacific for the longest possible period of time, which is only available at the TINRO-Center. 3) This valuable data should be organized into databases, based on which geo-information and other electronic information systems are prepared, and based on these map atlases and reference books on natural water resources, using automated workplaces created especially for this. 4) The resulting unique information support will be of great value not only for practical purposes, but also for science, both applied and fundamental. Next comes a summary of the many years of work on the practical implementation of this concept and the key achievements in this field obtained by the TINRO-Center by the end of 2015 are reviewed. At the end, some plans for the near future are outlined. 展开更多

Through system design and analysis from the aspects of entity categories, hierarchical design, attribute design, and the final function design and realization of the system, this paper develops a software application based on Arc-view platform with a view to solving the deficiencies of conventional groundwater dynamic management in managing the spatial graphics data. Using this application into the supporting automatic monitoring system of groundwater level helps to achieve the automatic analysis of attribute data, and offer a new, visual and efficient automated management tool. Moreover, the computer geospatial modeling can realize the quick query and spatial analysis of geographic information, and thus facilitating dynamic simulation and prediction of the research object. However, a multi-functional, multi-level groundwater level information management system is a complex system engineering, which requires continuous improvement of the structure, development of functions, and supplement of user models. 展开更多

This study examined the searching skills and extent of usage of electronic databases by Nursing, Midwifery and Public Health Nursing students in the University of Health and Allied Science (UHAS). The focus was on forty (40) level 300 students drawn from a universe of two hundred and forty six (246) of the School of Public Health (SPH). The study used quantitative method approach and the survey instruments were questionnaire, interview and observation. The data collected were analyzed and classified into the following themes: usefulness, extent of use, determinants of use of e-databases, searching skills, and main drawbacks of learning information literacy skills (ILS). Although all the respondents strongly agreed that e-databases are indispensable for academic and professional practice, findings revealed that majority of them have low quality of searching skills and that accounts for the sparse use of the e-databases. This positive association is proven by Pearson’s chi square test (0.000). The study also established that students’ attitude, academic loads and methodology of teaching were the challenges hindering the acquisition of ILS of students. As a consequence, the study recommends that Academic librarians should intensify their education on e-databases, the development of research guides and encourages stronger collaboration with faculty members in the teaching of ILS so that student nurses would be more adept in searching for information to enhanced scholarship and professional practice. 展开更多

As database system becomes more mature,people are paying more attention to the quality of information resources.It is of great urgency to improve user satisfaction of the quality with information resources so as to better meet their demands.This paper studies the authoritativeness,completeness,and timeliness of the content of information resources,constructs conceptual model of user satisfaction with the quality of information resources based on the customer satisfaction theory,and then verifies and revises the model by survey.The results show that the 'literature quantity', 'full text rate' and 'content authority' of information resources in database are the key indices influencing users’ quality satisfaction;users tend to measure quality satisfaction from the perspective of value,so that perceived value has greatest influence on quality satisfaction,while perceived quality has little influence on quality satisfaction. 展开更多
