Purpose: To develop a web-based program on blood-borne infection control and to examine the effect of the newly developed program on perceived threat of diseases, knowledge, preventive health behaviors for blood-borne infections, and incidence rates of accidental needle sticks and other sharp object injuries in nurses. Methods: The program was developed through the processes of analysis, design, development, implementation, and evaluation. The research design involved a nonequivalent control group for pretest and posttest experiments. The setting was a 745-bed general hospital located in Korea. Results: The program was designed and developed after consulting previous studies. After development of the program was completed, it was evaluated and revised by a panel of experts. The total score for perceived threat of diseases, knowledge, preventive health behaviors in the experimental group was significantly higher compared to the control group (p<.05). The incidence rates for needle sticks and other sharp object injuries in the experimental group were significantly lower compared to the control group (p<.05). Conclusion: Application of a Web-based, blood-borne infection control program is effective, and can be expanded to other healthcare workers who also have a high risk of blood-borne infections.

Enhancing the performance of maritime wireless communication has been highlighted by the issue of cell planning in the sea area because of lack of an appropriate Propagation Loss Model (PLM). To resolve the cell planning issue in vast sea areas, it was essential to develop the (PLM) matching the intended sea area. However, there were considerable gaps between the prediction of legacy PLMs and field measurement in propagation loss and there was a need to develop the adjusted PLM (A-PLM). Therefore, cell planning was performed on this adjusted model, including modification of the base station's location, altitude, and antenna azimuth to meet the quality objectives. Furthermore, in order to verify the availability of the cell planning, Communication Service Quality Monitoring System (CS-QMS) was developed in the LTE-Maritime project to collect LTE signal quality information from the onboard equipment at regular intervals and to ensure that the service quality was high enough to satisfy the goals in each designated grid. As a result of verification, the success rate of RSRP was 95.7% for the intensive management zone (IMZ) and 96.4% for the interested zone (IZ), respectively.

In modern society, the importance of inter-enterprise collaboration on supply chain is more emphasizing, depending on the industrial structure is going advanced. Therefore, the studies for advancement of inter-enterprise collaboration are taking, and especially the studies about how IT systems affect those advancement are taking. However, there are a shortage of recognition to each IT systems on B2B collaboration, additionally there is not much study of its application. In this study, we analyze the Performance Model relationship between the level and the importance of IT system for B2B collaboration in small and medium-sized enterprise, and draw a priority order for improvement of IT systems for its effective practical use.

This paper investigates the structural analysis and design of mechanical heart valve through the numerical analysis methodology. In a numerical analysis methodology application to the thickness minimization structural design of mechanical heart valve, fluid analysis is performed for the blood flow through a bileaflet mechanical heart valve. Simultaneously the kinetodynamic analysis is carried out to obtain the appropriate structural condition for the structural analysis. Thereafter the structural static analysis is also carried out to confirm the thickness minimization structural condition(minimum thickness shape of leaflet).

The goal of this project is to estimate the instream flow of the Han River Basin to ensure the adequate supply of suitable quality water for preservation and enhancement of aquatic ecosystems. A applied model is Physical Habitant Simulation System(PHABSIM) of Instream Flow Incremental Methodology(IFIM). The parameters which are needed to simulation by PHABSIM such as flow depth, velocity distribution and channel cover with cross section data are obtained by field survey. The Habitat Suitability Criteria with the application of univariate curve on Zacco platypus as a target species was able to be established by conducting the field investigation. The estimated results of ecological recommended instream flow by this study has important meanings that the future river management have to seriously take into account for the natural environment and functions of river system.

The application of 4PL could allow for the efficiency of many logistics operations to be greatly increased, for costs to be reduced, and for operations to become more responsive to consumer demand. It is also possible that higher services level and lower cost products could become available as a consequence. However, in order to implementing 4PL actually it is very important to be met to fundamental determinants of 4PL such as formation of logistics experts group, providing of total logistics service, capacity of IT, implementation of e-Business model, capacity of logistics consulting, higher logistics service level, logistics cost reduction, re-engineering of logistics process, focus of core competence etc.

The government expands its investment on R&D programs for economic growth, thus there is growing attention on the result of R&D Programs. This study proposes more improved measuring method for efficiency when the number of R&D programs is not enough to be for measuring efficiency analysis. It provides more various application method of factors on efficiency analysis. This study analyzes the influence of each input factor on efficiency by using partial efficiency concept. And it also determines input factors in similar influence throughout Spearman correlation coefficient. Finally, it suggests new method to improve discriminatory power of efficiency analysis by determining representative factors. Also, the proposed method can be practiced not only for national R&D programs, but also for other fields of research.

This aim of the study is to show the necessity of implementing an industrial innovation strategy with consideration given to characteristics of the industrial technology. The relationship between industrial technological characteristics and innovation performance is analyzed by using an innovation survey as well as a human capital corporate panel (HCCP). The time-lag effect is also examined. Findings of the analysis show that high-tech industries have entered the post catch-up technology innovation stage in the mid-2000s, but low-tech industries still seem to stay in the catch-up stage. In terms of technology policy, the additional technology innovation support policy should focus on enhancing the innovation capability of the middle and low technology industries, since high technology industries are already developing their own innovation capability. It is necessary to strengthen capacity building through technical cooperation with technology consulting, rather than providing technical support through suppliers.
