With the recent change of healthcare environment including rapid technological development, evidences are more and more important and necessary to support relevant policies in health technology assessment to provide safe and effective health services, utilizing medical resources efficiently. Despite of the emphasis on the importance of real world data and real world evidence in health care research, current infrastructure supporting clinical research is considerably weak due to absence of legal and institutional basis. However, in accordance with the Article 26 of the Health and Medical Technology Promotion Act, there is a limited legal apparatus that can be used only in public data with other dataset for the purpose of healthcare technology assessment at the National Evidence-based Collaborating Agency. Although the use of linked data from various sources was often required in the field of clinical research, it was not yet working well due to insufficient environmental conditions. In order to support the decision-making of medical practice and health care policies, data-linking platform for clinical research is needed. If the legal system that can link up to the data of the private institutions without violating the significant value such as the protection of private informations is established, it will be a decisive foundation reinforcing the researches and policy making processes for the improvement of the national health care system.

In this paper we analyze the technological accumulation processes in the Korean semiconductor industry from the institutional approach. Institutional approach, which is closely connected with Neo-Schumpeterian tradition, has emerged as an alternative theoretical framework to neoclassical approach to understand the process of producing technological knowledge. Traditional wisdom of neoclassical approach revealed the limitation to explain the complex nature of knowledge creation and diffusion. US patent data are analyzed in terms of the increasing trend of numbers and its content to measure the rate and direction of technological capability accumulation. This analysis shows that semiconductor technologies are one of the fastest growing fields among Korean technological activities. Moreover, the analysis of patent content suggests that fabrication technologies are the most important area within the technological development of semiconductors, whilst circuit design and testing technologies are beginning to increase in significance. In addition, it is examined how private sectors and public institutions have contributed to generate technological capabilities, and the relationship between them has been changed during the development processes. It is found that Korean firms enhanced their technological capabilities from the learning and assimilation of imported technology to enhanced in-house R&D capabilities in the later stage. The support of public institution and government policy also played significant role to this successful transformation in conjunction with vigorous R&D investment of public sector.

Digital technology has become a new economic and social force, reshaping traditional business models, strategies, structures, and processes. This is a challenge for human capital to develop continuously in this dynamic era; one of the solutions is digital entrepreneurship. Digital entrepreneurship focuses on creating new ventures and transforming existing businesses by developing novel digital technologies or novel usage. Further, digital technology has also enabled the growth of the sharing economy, linking owners and users, and disrupting the previous dualism of businesses and customers. This paper provides a novel contribution regarding the emerging concept of Digital Entrepreneurship. Based on a qualitative literature review and interview with university staff, lecturers, and students in four large public and private universities in West Java and DIY Province, an interpretative framework for Digital Entrepreneurship has been proposed, which comprises of the following components: motivation (the rationale for the adoption of digital technology for academic entrepreneurship), stakeholders (the stakeholders involved through digital technology to achieve the academic entrepreneurship goal), process (the processes of academic entrepreneurship supported by digital technologies), and business form (the emerging forms of digital academic entrepreneurship). This research also shows several alternative government policies to improve digital entrepreneurship in the academic environment.

Learners are often posited in a paradoxical situation where they are not fully involved in decision making processes on how to learn, in designing their tools. Cognitive artifacts in e-learning are supposed to effectively support learner-centered e-learning. The purpose of the study is to analyze cases of cognitive artifacts and to inquire those design principles for facilitating the learner-centered e-learning. Four research questions are suggested: First, it will be analyzed the characteristics of learners with respect to design of cognitive artifacts for supporting the learner-centered e-learning. Second, characteristics of four cases to design cognitive artifacts in learner-centered e-learning environment are analyzed. Third, it will be suggested the appropriate design principles of cognitive artifacts to facilitating learner-centered learning in e-learning environment. Four cases of cognitive artifacts design in learner-centered e-learning was identified as follows: Wiki software as cognitive artifacts in computer-supported collaborative learning; 'Play Around Network (PAN)' as cognitive artifact to monitor learning activities in knowledge community; Knowledge Forum System (KFS) as a cognitive artifact in knowledge building; cognitive artifacts in Courses-as-seeds applied meta-design. Five design principles are concluded as follows: Promoting externalization of cognitive artifacts to private media; Helping learners to initiate their learning processes; Encouraging learners to make connections with other learners' knowledge building and their cognitive artifacts; Promoting monitoring of participants' contributions in collaborative knowledge building; Supporting learners to design their cognitive artifacts.

Background: Cervical cancer is a common, preventable and manageable disease in women worldwide. Objectives: This study was conducted to determine the cost of follow-up for suspicious precancerous cervical lesions within a screening program using Pap smear or HPV DNA test through the decision tree. Materials and Methods: Patient follow-up processes were determined using standard guidelines and consultation with specialists to design a decision tree model. Costs of treatment in both public and private sectors were identified according to the national tariffs in 2010 and determined based on decision tree and provided services (visits to specialists, colposcopy, and conization) with two modalities: Pap smear and HPV DNA test. The number of patients and the mean cost of treatment in each sector were calculated. The prevalence of lesions and HPV were obtained from literature to estimate the cost of treatment for each woman in the population. Results: Follow-up costs were determined using seven processes for Pap smear and 11 processes for HPV DNA test. The total cost of using Pap smear and HPV DNA process for each woman in the population was 36.1$ and 174$ respectively. Conclusions: The follow-up process for patients with suspicious cervical lesions needs to be included in the existing screening program. HPV DNA test is currently more expensive than Pap smear, it is suggested that we manage precancerous cervical lesions with this latter test.

A Purpose. As organizations become more team oriented, research on teams continues to increase especially involving how teams contribute to organizational performance and effectiveness. Although there has been existing research on Kaizen teams in the private sector, very little research has included Kaizen teams in the public sector. In this paper, we present a method to study Kaizen teams in a local Spanish government that have been using Kaizen teams for more than ten years. Design/methodology/approach. Quantitative research was adopted for this study. Twenty teams participated in the study by filling out the Team Learning and Development Inventory (TLI) proposed by Lingham (2004). In addition, we interviewed members of the teams in order to clarify and assure our quantitative results. Findings Based on the findings, we propose that Kaizen teams should practice both Continuous (CI) and Process Improvements (PI) in their projects. We also propose that Kaizen teams should not be teams skilled only at developing better improvement processes (both CI and PI) for the organization but that such teams should also be skilled at engaging in team development using both CI and PI processes internally-a Kaizen within Kaizen teams approach. Research limitations. Its based in one case study. However, it is working paper and the research project still is developing. Practical Implications (if possible). Serve as a guide to practitioners (Public managers) who desire to understand how their Kaizen teams involves both internal (conversational spaces) and external (methodology) perspectives that would contribute to both team and organizational effectiveness. In this paper, we focus on the Internal Processes (both CI and PI) using the TLI as an effective method for Kaizen teams to engage in the Kaizen process. Originality/value. This study is one of the first to look at team's performance using Team Learning and Development Inventory in Spain's public sector. It is also the first to mention about the relationship of the team's performance and the implementation of process improvement methodologies in Spain local government environment.
