The use of mobile learning for visually impaired learners school in tolerance education contents

Mobile learning technologies become alternative way of learning to foster knowledge creation, skills development for learners. Especially in gaining open, equality and access in education, there is an intensified need to consider tolerance education content. Using mobile learning technologies and having particular skills to use mobile technologies for visually impaired adult learners have been investigated in this study. Mix method was employed and questionnaire and at the same time semi-structured interviews provide large amount of data to reveal challenges and possible strategies in enhancing mobile learning technologies for visually impaired adult learners. Thirty nine adult learners become part of this action research voluntary basis. The research reveals the practice of mobile learning technologies and its challenges in developing country and also shows how visually impaired learners need mobile learning and education to become digital citizen within the society. In this respect, using mobile technologies and having knowledge, skills for practicing mobile technologies need to be considered in detail for visually impaired adult learners based on proposed strategies. It is revealed that tolerance education content is important and can be diffused through the impact of technology and management. For further studies, contemporary mobile technology applications can be developed and tested with proposed model as underlined in this study.

An exploration of core competences of newly qualified nurses: a case study

The health care system is undergoing rapid change. Given the ever changing healthcare environment the responsibilities, competencies and skills expectations of new nurses is escalating. Therefore, there is need for a deeper and more systematic assessment of the competences affect on core competence of nurses. With this background, this paper attempts to identify and analyze the core competence for nurses. Thus, a DEMATEL method is applied. The DEMATEL not only can convert the relations between cause and effect of criteria into a visual structural model, but can also be used as a way to identify the key factors. The DEMATEL can be used as an effective method to handle the inner dependences within a set of criteria. Results show that the Personal feature Perspective is the causal dimension for the evaluation of core competences. This paper draws on the research results for managerial practice implications.

Selecting the key research areas in nano-technology field using technology cluster analysis: A case study based on National R&D Programs in South Korea

In the early 21st century, Korean government issued a policy recommendation that Korean public research institutes should select strategic research fields to concentrate their resources, based on a careful review of the various strategic R&D factors. The government has emphasized the “selection and concentration” strategy for the efficient use of R&D resources and as a way to increase the national competitiveness of Korea. This paper suggests a method, a “Technology Cluster Analysis,” for selecting the strategic research areas, mainly targeting large, multi-disciplinary and long-term programs. The technology cluster analysis groups near technologies together based on key indicators. In this study, the method is applied to national R&D programs in the nano-technology field. Fifty-six nano-technologies are analyzed and grouped into three main clusters based on the survey data from 180 experts. Technological distances and correlations among individual technologies are depicted by hierarchical dendrogram. Three main clusters in nano-technology field are found and termed nano-materials, nano-devices, and nano-bio. These three clusters are expected to be the core technology clusters in nano-technology field in South Korea.
