In health care, technologies should be diffused and adapted if their safety and efficacy has been established and determined. The role of making such a decision, that is whether the safety and efficacy of a certain technology is established, is encapsulated within the processes of a "health technology assessment (HTA)." In this way, HTA has had a central role in the development of a transient healthcare, which is constantly adapting to meet ever-evolving demands. HTA is a very useful concept and tool for providing information for evidence-based decision making. And evidence-based decision making is critical when resources should be allocated in health care. Therefore, from all interest parties in society, the consensus on the necessity for conducting HTA should be brought. And governments should incorporate results from HTA into policy making as possible as they can. © 2013 The Korean Tissue Engineering and Regenerative Medicine Society and Springer Science+Business Media Dordrecht.

This paper utilizes grounded theory in studying the sharing of experiences by a group of university hospital medical doctors. Based on empirical data and the application of knowledge sharing theory, a theoretical framework for a comprehensive approach to knowledge sharing by doctors in the long term is developed. The 20 participants in this study all have more than 10 years of medical experience and are specialists working in university hospitals in Korea. In addition each participants also hold the position of associate professor or higher at the associated medical school. Four in-depth interview and studies were conducted. For the paradigm model of grounded theory, the concepts were drawn from the causal condition, contextual condition, main context, intervening condition, interaction strategy and result. Low level categories were identified and then high level categories were extracted from them. In this study, 'the process of development through the sharing of experience' is identified as being the key category. This study is meaningful in that it, unlike existing studies of knowledge sharing, tries to understand and explain the significance and process of knowledge sharing as experienced by medical doctors. While most of the literature about knowledge sharing focuses on a quantitative analysis, this study utilizes qualitative methodology, particularly grounded theory, to understand the substance or meaning the doctors experienced whilst sharing their knowledge. The study suggests how to improve the quality of the knowledge concerned, organize such knowledge and/or advance its utilization and sharing. © 2013 SERSC.

The principal objective of this study was to investigate the mediating and moderating effects of product involvement and trust toward websites in relation to the effects of the attributes of web advertisements on customers' purchase intentions. We collected data consisting of a total of 264 responses from individuals with previous experience with purchasing products from online shopping mall sites, and utilized the PLS (partial least squares) method to analyze the collected data. Our findings demonstrated that consumers with greater product involvement tended to shop in shopping malls, where they could obtain more information on products, and that consumers with low product involvement tended to be more willing to consider entertainment. Additionally, consumers with higher levels of trust toward websites tended to be influenced by perceived entertainment and thus stay longer at shopping sites; conversely, consumers with low levels of trust toward websites tended to be more willing to consider perceived informativeness as minimizing environmental uncertainty. On the basis of our results, online shopping malls must stress the intrinsic attributes of products to attract highly-involved consumers and must present a benevolent corporate image for consumers concerned with better service. Our results also demonstrated that, for less-involved consumers who wish to search for products to present, it may be appropriate to mix entertainment components with product information, and also to implement creative web interface designs for more effective browsing. © 2010 Elsevier Ltd.

Although a large number of studies have examined the impact of housing and neighborhood characteristics on housing prices, they have not systematically considered the impact of physical conditions of the immediate neighborhood on housing prices, specifically conditions associated with physical disorder. Most likely, this failure has occurred because such data do not exist in published form. The main purpose of this study is to focus on the impact of physical disorder at the microneighborhood level on property resale values by using a hedonic-price-model approach. The results highlight the costs that neighbors may inflict on one another by not maintaining their houses and neighborhood. For the first time, the results provide specific estimates of the cost associated with individual physical-disorder attributes. The results are also indicative of the importance externalities play in neighborhood change and the need for policy intervention in preventing neighborhood decline. © 2011 American Society of Civil Engineers.

The traditional Ethylene Tetra Fluoro Ethylene (ETFE) foil cushion is in the form of air cushion, whose structural stiffness is offered by the inner air pressure. Because the air supply and control systems are needed, air cushion structures cost extra energy and need much maintenance. In order to overcome the shortcomings of air cushion, the ETFE foil spring cushion that uses a spring to take the place of air pressure is developed in this paper. At first, the analytical method for shape finding analysis and stress analysis of the spring cushion is described in the paper. A numerical example is shown by means of the software package ANSYS and the suggested method so as to verify the validity of the method. Then, a model experiment on the ETFE foil spring cushion is carried out. In the loading test, the compression of spring is recorded and the experimental results are compared with the analytical results. At the end of the paper, an experimental hall using both ETFE foil air cushion units and spring cushion units as its roof structure is introduced. Through the construction and daily use of the experimental hall, the spring cushion system shows advantages such as easier construction, needing no air supply and control equipments, no running energy and little maintenance compared with the air cushion system. © 2011 Elsevier Ltd.
