Grid computing has a large scale virtual computing environment that enables a collaborative processing through sharing resources of geographically distributed organizations. In recent year, the development of wireless networks and mobile devices enables mobile devices to consider as a resource of the grids. However, there are some problems such as low performance of processors, small capacity of storages, limited capacity of battery, and low bandwidth. In this paper, to overcome these limitations occurred in mobile grid environments, we proposed a proxy-based mobile grid system. Our proposed system enables mobile devices to play roles as a resource consumer and a resource provider and to collaborate with wired grids through a mobile router. Also, we propose an adaptive job scheduling scheme to cope with context changes of mobile devices and compare our scheduling scheme with other scheduling schemes using a simulation tool, SimGrid, to verify the validity of our job scheduling scheme.

Background: Insufficient training in infection control and occupational health among healthcare workers (HCWs) in countries with high human immunodeficiency virus (HIV) and tuberculosis (TB) burdens requires attention. We examined the effectiveness of a 1-year Certificate Program in Occupational Health and Infection Control conducted in Free State Province, South Africa in an international partnership to empower HCWs to become change agents to promote workplace-based HIV and TB prevention. Methods: Questionnaires assessing reactions to the program and Knowledge, Attitudes, Skills, and Practices were collected pre-, mid-, and postprogram. Individual interviews, group project evaluations, and participant observation were also conducted. Quantitative data were analyzed using Wilcoxon signed-rank test. Qualitative data were thematically coded and analyzed using the Kirkpatrick framework. Results: Participants recruited (n = 32) were mostly female (81%) and nurses (56%). Pre-to-post-program mean scores improved in knowledge (+12%, p = 0.002) and skills/practices (+14%, p = 0.002). Preprogram attitude scores were high but did not change. Participants felt empowered and demonstrated attitudinal improvements regarding HIV, TB, infection control, and occupational health. Successful projects were indeed implemented. However, participants encountered considerable difficulties in trying to sustain improvement, due largely to lack of pre-existing knowledge and experience, combined with inadequate staffing and insufficient management support. Conclusion: Training is essential to strengthen HCWs' occupational health and infection control knowledge, attitudes, skills, and practices, and workplace-based training programs such as this can yield impressive results. However, the considerable mentorship resources required for such programs and the substantial infrastructural supports needed for implementation and sustainability of improvements in settings without pre-existing experience in such endeavors should not be underestimated.

The purpose of research is to explore the direction of building a collaborative supply chain, which may enhance the competitiveness of firms and their project-based supply chain. Large-scale plants or large-scale buildings construction is referred to as a EPC project. To identify a collaboration mechanism in the project-based supply chain, the empirical research was conducted on the interrelationship between the absorption capacity of firms participating in the EPC project, the incentive norms, the goal congruence with supply chain, and the ability of respond to changes of the task of supply chain. PLS-SEM was used as an analysis method to verify the research model. It is expected that the results will help inform the need for SCM, the importance of the incentive norms and the goal congruence in the supply chain of EPC project.

The increasing penetration of distributed energy resources on the distribution networks have brought a number of technical impacts where voltage and thermal variations have been identified as the dominant effects. Active network management in distribution networks aims to integrate distributed energy resources with flexible network management so that distributed energy resources are organized to make better use of existing capacity and infrastructure. This paper propose active solutions which aims to solve the voltage and thermal issues in a distributed manner utilizing a collaborative approach. The proposed algorithms have been fully tested on a distribution network with distributed generation units.

Despite the importance of university-industry collaboration, issues pertaining to the characteristics of collaborating firms, their modes of interaction, and the relationship between these modes and outcomes are not well-researched. The impact of country's development on these issues is also unclear. This case study examines Japan and Thailand-respectively representing developed and developing countries-and features the following key findings: 1) the characteristics of firms affect modes, with large Japanese firms being more collaborative with universities, whereas Thai SMEs significantly collaborate more with universities; 2) the relationship between modes in Thai firms is stronger than those of Japanese firms because in Thailand, perhaps due to weak technological capacity, R&D collaboration is conducted alongside university consultancy services; and 3) in Japan, R&D and human resource development collaboration lead to product innovation, whereas different outcomes are expected from different modes in Thailand. Apparently, trivial informal collaborations do have significant impact on innovation.

Purpose: To develop strategies for research and development (R&D) in nursing service based on the policy direction of government supported R&D in Korea. Methods: This was a descriptive study to develop strategies for promoting R&D in nursing by analyzing investment trends and status quo, policy directions, and implementation of the details of government supported R&D through government reports, websites of relevant agencies and literature reviews. Results: Few nursing experts participated in clinical research on overcoming major diseases and in R&D for well-being and care. Development of nursing topics that meet the direction of government supported R&D were lacking. Insufficient implementation of nursing service R&D in a timely manner equipped with a performance-based system. Few research studies in R&D projects that included research using big data or contributing to developing medical instruments. Finally, an insufficient number of nursing specialists participated on government R&D advisory committees. Conclusion: For nursing service R&D development efforts should be toward quantitative expansion and qualitative improvements by sensitively recognizing policy direction of government supported R&D. The promotional capacity of nursing service R&D must be reinforced through a multidisciplinary approach and collaborative association with other professionals and the inclusion of nurse specialists on government R&D advisory committees.

Objectives: This paper discusses the current contexts of the collaboration between public health centers(PHCs) and community partners for health promotion. Then it suggests directions for the development and enhancement of the collaboration. Methods: The discussion in this paper is based on key literature on community health promotion, including literature reviews and case reports. Results: PHCs are mostly engaged in networking and cooperation rather than collaboration with the community. A typical pattern of cooperation is where PHCs provide healthy-setting types of programs to the community in single-partnered relationships. Current cooperation rarely involves co-planning by a multi-partnered partnership, and is greatly influenced by the interest of PHC directors and PHC performance evaluation indicators. Systems change is recommended to foster collaboration for community health promotion. Such change involves: shared understanding of health promotion and collaboration, inclusion of collaboration mechanism in public health governance, leadership development, capacity enhancement of all partners. role definition of PHCs for community collaboration, and development of collaborative system, at the least. Conclusions: At this point where collaboration should be more than rhetoric, multi-faceted, intersectoral, and concurrent approaches are required to create discourses, to develop cases, and to share experience for actual realization of collaboration for community health promotion.

The current behavior recognition system don't match data formats between sensor data measured by user's sensor module or device. Therefore, it is necessary to support data processing, sharing and collaboration services between users and behavior recognition system in order to process sensor data of a large capacity, which is another formats. It is also necessary for real time interaction with users and behavior recognition system. To solve this problem, we propose fog cloud based behavior recognition system for human body sensor data processing. Fog cloud based behavior recognition system solve data standard formats in DbaaS (Database as a System) cloud by servicing fog cloud to solve heterogeneity of sensor data measured in user's sensor module or device. In addition, by placing fog cloud between users and cloud, proximity between users and servers is increased, allowing for real time interaction. Based on this, we propose behavior recognition system for user's behavior recognition and service to observers in collaborative environment. Based on the proposed system, it solves the problem of servers overload due to large sensor data and the inability of real time interaction due to non-proximity between users and servers. This shows the process of delivering behavior recognition services that are consistent and capable of real time interaction.

Conducted within the methodological framework of action research, this study examines the ways in which a beginning science teacher in a Korean elementary classroom engaged in collaborative research with her own students to resolve problems preventing effective science teaching and learning. Specifically, this study uses cogenerative dialogue between teachers and students to develop new teachers' knowledge of how to manage the classroom to be able to more effectively implement inquiry instructional strategies and knowledge of students as learners. Findings from this research suggest that by involving students in cogenerative dialogues, beginning teachers are provided with valuable insights into how elementary students think about school, science, and teaching and learning, which can help expand a beginning teacher's capacity to be an effective science teacher of science for all learners, especially diverse learners. These findings suggest that teacher education programs could better support beginning teachers by placing greater emphasis on how to conduct action research, including how to implement cogenerative dialogues to catalyze positive changes in their own classrooms. We conclude by discussing the important implications this research has for supporting new teachers struggle to effectively teach science and who would benefit from using strategies to foster improved relationships with their students and improved understanding about the challenges faced by diverse learners in their classroom.
