  • Purpose While individuals have unique abilities for planned behavior, they also often act irrationally. In this study, we draw on myopic loss aversion perspective as a meta-theoretical lens to explain why mobile applications users have inertia from updating their applications, ultimately leading them to use current version of applications. Design/methodology/approach Based on a survey of 219 users, this study conducts its research model using partial least square analysis and also demonstrates that both subconscious triggers (habit and anxiety) of system 1 thinking and conscious triggers (sunk cost and transition cost) of system 2 thinking promotes user's inertia, thus leading to the willness to continue use current versions. Findings By grounding the research model in the combination of both status quo bias and dual information processing theory from the behavioral economics, this study provide an alternative theoretical lens to describe why mobile users hesitate to update their applications. The results of this research show that all triggers have significant impacts on inertia. This study also found that the relationship between inertia and willingness to continue to use current version was positively significant.

  • Purpose: The purposes of this study were to review the research trends and to identify developmental direction of studies on community interventions according to the ecological model for workers with cardiovascular diseases (CVD) risk factors. Methods: Electronic databases including PsycINFO, PubMed, EMBASE, CINAHL, and Cochrane Library and the reference lists of articles were searched. All articles were assessed in relation to inclusion and exclusion criteria, resulting in 29 researches being reviewed. Each review was critically appraised by two authors using a guideline of PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses). Results: Nowadays, interventions in organizational level, integrated and web-based interventions are increasing to prevent CVD risk factors for workers. Even though the importance of psychosocial aspects to prevent CVD, the only 2 studies included psychosocial factors in the outcome variables. Also, 14% among 29 researches were based on theories. Conclusion: Psychosocial factors such as job stress, depression, and emotional labor could be CVD risk factors. Therefore, interventions including psychosocial aspects are needed to prevent workers' CVD risks more effectively. Theory-based interventions are needed to support interventions' effects and to develop the nursing science.

  • As cities face increasing problems such as aging, environmental pollution and growth limits, we have been trying to incorporate sustainability into urban planning and related policies. However, it is very difficult to generate a 'sustainable spatial plans' because there are trade-offs among environmental, society, and economic values. This is a kind of non-linear problem, and has limitations to be solved by existing qualitative expert knowledge. Many researches from abroad have used the meta heuristic optimization algorithms such as Genetic Algorithms(GAs), Simulated Annealing(SA), Ant Colony Optimization(ACO) and so on to synthesize competing values in spaces. GAs is the most frequently applied theory and have been known to produce 'good-enough plans' in a reasonable time. Therefore we collected the research on 'spatial optimization model based GAs' and analyzed in terms of 'study area', 'optimization objective', 'fitness function', and 'effectiveness/efficiency'. We expect the results of this study can suggest that 'what problems the spatial optimization model can be applied to' and 'linkage possibility with existing planning methodology'.

  • The following thesis has been composed with the inspiration attained from Paul Ardenne's conception on Contextual Art. In Europe and in the United States, there is a group of artists who emphasize in the importance of artist's participation in social, political, economical, environmental and moral issues. Since the 1960's, these artists have pondered on Modernism's ideas where art is contextually separated from humanly issues whereas the manners of such artists put on emphasis in the intent to participate in the real human social and ethical issues. Forerunner in this field of art such as Wolfgang Leib display hybrid or meta style in their work. His work displays a quadrilateral form of pollen which represents the simultaneous blending of two mixed ideas such as the abstract from the real. Thus heterogeneous style and philosophy which includes a range of medias and today's trend is observed in Contextual Art. Such art form is also found in landscapes where it is not seen as an observable object but rather an interactive object. It is correlated to Arte Povera of the Italian Art Movement, Support-Surface of the French Art Movement and lastly to the Fluxus. Through these art movements, we find a mutual antipathy towards putting art for sales in the capitalism market and reflect the social role of art in postmodern era.

  • The main issue of boron doped p-type czochralski-grown silicon solar cells is the degradation when they are exposed to light or minority carriers injection. This is due to the meta-stable defect such as boron-oxygen in the Cz-Si material. Although a clear explanation is still researching, recent investigations have revealed that the Cz-Si defect is related with the boron and the oxygen concentration. They also revealed how these defects act a recombination centers in solar cells using density function theory (DFT) calculation. This paper reviews the physical understanding and gives an overview of the degradation models. Therefore, various methods for avoiding the light-induced degradation in Cz-Si solar cells are compared in this paper.

  • This review organises the fragmented management literature on platform business according to a conceptual map and a meta-theoretical scheme. Since the early 2000s, numerous researchers have examined platform business and two-sided networks with platform business and strategy being an important business innovation model for many industries, creating value primarily by enabling direct interactions. Platforms such as Google or Amazon contain a common set of rules and components in most user transactions. Thirty-two core papers and books on Strategic Management Journal, Industrial Economics and Operation Management-related disciplines are reviewed, with further observations on how cumulative research streams on the platform are carried out independently from each academic perspective. The first of the two arguments in this paper is that because interactive relationships bridge the platform and stakeholders such as end-users and developers, it is crucial for platform companies to be aware of their relationship with stakeholders in order to support and sustainably provide content to their platform. The second is that integrative perspectives are essential due to the low number of interdisciplinary investigations conducted thus far. The paper's final section deals with implications for theory and practice, concluding that integrative studies and interactive relationship studies should be the main research streams in future platform research.

  • Purpose: This study was done to analyze the trends in excercise-related research in nursing and non nursing research studies published in Korea. Method: Two hundred and ten research studies published in Korea between January, 1990 and December, 2002 were analyzed according to the criteria of methological characteristics, pattern of excercise-related program, and measurement index of exercise effect. Results: There were twice many papers from nursing compared to other fields, and many experimental studies in nursing were done with more variety than in non nursing fields. Aspects of exercise pattern, such as excercise type. duration, and frequency, exercise-intervention pattern, and applying theory were especially included. When patterns of excercise therapy and index of exercise effect were analyzed, each researcher used their own unique excercise contents and intervention patterns(excercise time per week, exercise duration at each time period, excercise, intervention time, and etc). Conclusion: For the importance of exercise therapy to health improvement and the proper suggestion of exercise therapy on the basis of this research, meta-analysis of exercise effect are needed, and with this analysis, intervention patterns of exercise, development of standard exercise therapy, and identification of exercise effects are required.

  • The market structure and consumer characteristics are changing dynamically according to internet shopping industry developing based on Web 2.0. But, there is absent typical online service after 'Cyworld.' The social shopping sites based on social networking reflect to present phenomenon that collective intellect, information sharing, participate in making information. The social shopping sites are not limited in particular shopping sites but include all of sites in online. So, consumers can copy various products and display on their own blog provided from social shopping sites and make some purchase reviews and any comments about products can lead transactions among social shopping sites. So, it might be a one of meta-shopping mall like 'Naver.' As the social shopping sites are new form, we just applied to TAM theory to figure out acceptance factors using SEM. The perceived enjoyment affect to usefulness, ease of use and using intension. The perceived ease of use also affect to usefulness and the usefulness affect to using intension positively. But the perceived ease of use was for nothing in using intension. Finally, we provided managerial implications to activate domestic online shopping industry and theoritical meaning using extended TAM.

  • This study develops an effective method for sentiment analysis of user-generated content on drug review websites, which has not been investigated extensively compared to other general domains, such as product reviews. A clause-level sentiment analysis algorithm is developed since each sentence can contain multiple clauses discussing multiple aspects of a drug. The method adopts a pure linguistic approach of computing the sentiment orientation (positive, negative, or neutral) of a clause from the prior sentiment scores assigned to words, taking into consideration the grammatical relations and semantic annotation (such as disorder terms) of words in the clause. Experiment results with 2,700 clauses show the effectiveness of the proposed approach, and it performed significantly better than the baseline approaches using a machine learning approach. Various challenging issues were identified and discussed through error analysis. The application of the proposed sentiment analysis approach will be useful not only for patients, but also for drug makers and clinicians to obtain valuable summaries of public opinion. Since sentiment analysis is domain specific, domain knowledge in drug reviews is incorporated into the sentiment analysis algorithm to provide more accurate analysis. In particular, MetaMap is used to map various health and medical terms (such as disease and drug names) to semantic types in the Unified Medical Language System (UMLS) Semantic Network.
