The advancement of information technology provides a wide range of options for the corporate to cope with new business environments. As with most other businesses, the utilization of the logistics information technology can be an instrument to enhance the competitiveness of the company. Therefore it is essential to analyze how companies utilize and verify the relationship between company business performance and the level of information technology utilization, which is the objective of this paper. The questionnaire was sent to 300 companies listed on the stock market at random The author received 176 responses of which 142 were complete and valid. According to the analysis of questionnaires, the adoption level of information technologies was dependent on the perception of top managers on the importance of information technology in business competitiveness. Furthermore the level of relation between the information technology adoption and business performance was significant. Therefore businesses need to increase the utilization of information technologies, such as establishment of logistics information system, network with other business partners in order to business logistics performance.

Purpose: This study was to identify the factors affecting utilization of clinical nurses' hospital information system. Method: Using a convenient sampling, 450 nurses from 9 secondary or tertiary university hospitals in B metropolitan city were selected. Results: The extent that nurses utilize the hospital information system was 3.22 point on average. The hospital information system utilization was positively correlated with personal information utilization skill, information-oriented education, attitude toward computer, and support of the chief manager, while as negatively correlated with the organizational atmosphere. The causal factors of influencing on the hospital information system utilization were personal information technology, education experience of the hospital information system, age, attitude toward computers, education level and support of the chief manager. The total eigenvalue of the variables was 38%. The major variables of influencing on the hospital information system utilization were the personal information technology and education experience of the hospital information system. Conclusions: Thus, nurse managers should provide training courses to improve personal information technology of nurses, and consistently promote them so that nurses can readily apply the hospital information system which have been recently introduced in various ways and thus improve the efficiency of nursing.

Since the existing anti-jamming methods, including intelligent methods, have difficulty against high-speed reactive jamming, we studied a new methodology for jamming utilization instead of avoiding jamming. Different from the existing jamming utilization techniques that harvest energy from the jamming signal as a power supply, our proposed method can take the jamming signal as a favorable factor for frequency detection. Specifically, we design an intelligent differential frequency hopping communication framework (IDFH), which contains two stages of training and communication. We first adopt supervised learning to get the jamming rule during the training stage when the synchronizing sequence is sent. And then, we utilize the jamming rule to improve the frequency detection during the communication stage when the real payload is sent. Simulation results show that the proposed method successfully combated high-speed reactive jamming with different parameters. And the communication performance increases as the power of the jamming signal increase, hence the jamming signal can help users communicate in a low signal-to-noise ratio (SNR) environment.

The study examined information retrieval tools as predictors for information resources utilization, four research questions, and four hypotheses were made to guide the study. A descriptive survey was adopted for the study. Random sampling technique was used to select sample of 393 from a population of 557 academic staff registered in the University of Port Harcourt library. The questionnaire was adopted as a data collection instrument titled Information retrieval as predictors for information resources utilization (IRPIRUQ). Data were analyzed using both simple and multiple regression while analysis of variance (ANOVA) associate with regression was used for testing the hypotheses at 0.05 alpha level. The study revealed that information resources are under utilized as the OPAC and Online Databases are not easily accessed. Further findings showed that the academic staff made use of internet search engines more often than the OPAC and online databases. It was recommended among others that a new library software be installed in place of KOHA for wider connectivity and adequate distribution of software that will aid usage of the online databases and OPAC.

Purpose: The purpose of this study was to draw practical implications applicable to the field by analyzing a double-mediator model of social participation and depression in relation to the utilization of Information Communication Technology (ICT) and cognitive function. Methods: The data from the Fifth Living Profiles of Older People Survey in Korea was used, and the sample included 3,925 people, 75 years of age or older. Descriptive statistics, correlation analysis, and the PROCESS macro test were used for verification of the double mediator model. Results: The results were as follows: First, ICT utilization was rated at an average of 1.4 out of 10, social participation at an average of 1.1 out of 7, depression at an average of 3.72 out of 15, and cognitive function at an average of 22.42 out of 30. Second, ICT utilization has a significant effect on cognitive function. Third, the mediating effects of social participation between ICT utilization and cognitive function were significant. Fourth, the mediating effects of depression between ICT utilization and cognitive function were not significant. Fifth, the serial double mediator effects leading to ICT utilization, social participation, depression, and cognitive function were significant. Conclusion: The study discussed the implications of maintaining and protecting cognitive function in the vulnerable elderly through the utilization of ICT.

This study aims to identify the causation effect between technostress and utilization of Internet information and meditation effect of information service acceptability between technostress and Internet information utilization. The data were collected from 503 woman farmers aged 20 to 65 across the country. The analysis performed a three-stage mediated regression of Bron, & Kenny (1986), using the SPSS 21.0 statistical package. The importance of accepting information services has been identified in the Sobel test. According to the analysis of the medium effect on information service acceptability, information service acceptability has a partial medium effect on the technological stress of woman farmers and the level of Internet information utilization. In order to lower the technology of woman farmers in the future, it is necessary to find ways to improve new perceptions of information technology and increase acceptability of information services.

Cloud computing promises high performance and cost-efficiency. However, most cloud infrastructures operate at a low utilization, which greatly adheres cost effectiveness. Previous works focus on seeking efficient virtual machine (VM) consolidation strategies to increase the utilization of virtual resources in production environment, but overlook the under-utilization of backup virtual resources. We propose a heuristic time sharing policy of backup VMs derived from the restless multi-armed bandit problem. The proposed policy achieves increasing backup virtual resources utilization and providing high availability. Both the results in simulation and prototype system experiments show that the traditional 1:1 backup provision can be extended to 1:M (M≫1) between the backup VMs and the service VMs, and the utilization of backup VMs can be enhanced significantly.
