If the status of surgical margin has by itself a significant impact on survival, wider surgical margins would be needed, and larger functional sequelae justified. However, if the status of surgical margin does not affect survival, closer surgical margins with a lower loss of function may be advantageous. The impact of surgical margin status on survival in extremity STS remains to be clearly defined. Therefore, a systematic review and meta-analysis were conducted to determine the impact of SM status on survival in extremity STS. Methods: A literature search of the National Library of Medicine and National Institutes of Health (PubMed), EMBASE, and Cochrane Controlled Trials Register (CENTRAL) electronic database and by hand searching reference lists of original studies was performed. We searched the studies with the following text words and/or Medical Subject Heading (MeSH) terms: neoplasm or sarcoma or connective tissue or soft tissue and extremity and margin. The quality of each study was assessed using the Newcastleโ€“Ottawa Scale (NOS). A pooled HR was analyzed using an inverse variance weighting method and the random effects model or fixed effect model was selected according to heterogeneity. For identifying publication bias, Beggs test was used. Results: A total of 6 studies were included in the meta-analysis. All six studies were conducted at a single institution and were of high quality (NOS โ‰ฅ 7). Meta-analysis of all 6 studies showed that a positive SM predicted poor 5-year survival compared to patients with negative surgical margin in a random-effects model with moderate heterogeneity among studies (SHRs = 1.56, 95 % CI 1.12โ€“2.17test for heterogeneity p<0.002, Iยฒ = 64.18%). Formal evaluation using Beggs test revealed no evidence for significant publication bias in the 5-year survival (p = 0.086). Conclusion: This meta-analysis supports the hypothesis that positive surgical margin is a poor prognostic factor for survival in extremity STS. Our study provides guidance for surgeons undertaking limb salvage surgery in deciding the extent of the SM and its effect in terms of survival.Introduction 1 Material and Methods 2 Results 5 Discussion 11 References 16 Abstract in Korean 22Maste

Recently social movement researches have integrated two contrasting perspectives, collective-oriented paradigm and resource mobilization paradigm. Because social movement is made of its strategy and condition, it is required to analyze synthetically two aspects. This research tries to explore characteristics of social movement in the information era,focusing on network's roles. Network is understood as a important tool forming collective identity and mobilizing resource in modern social movement repertoire in the aspects of identity, mechanism and strategy. Furthermore, it is expected that coevolution of citizenship and information communication technologies will more rapidly change social movement repertoire

Online space has formed multi-level public sphere based on distributed networks and various communications platform. In the last candlelight demonstration, online public sphere was the epicenter triggering a broad political mobilization through the bottom-up agenda-setting and public opinion formation. Especially the Agora of the Media Daum was called the Mecca of the candlelight vigil. In this regard, this study is to explore the function and influence of the Agora as the public sphere. Firstly, the political and economic context and the characteristics of the communication platforms that has formed the Agora will be discussed. Secondly, the behavioral characteristics and activity strength of participants of the Agora will be discussed. Thirdly, the features of rippling and agendasetting of the anti-U.S. beef import issue are to be investigated. Lastly, public debating level is to be discussed by content analysis of the Agora posts
