Objective : There was no abundance of data on the use of anticoagulant in patients with previous high risk of thromboembolic conditions under a newly developed intracranial hemorrhage in Korean society. The purpose of this study was to evaluate the safety of discontinuance and suggest the proper time period for discontinuance of anticoagulant among these patients. Methods : We reviewed the medical records of 19 patients who took anticoagulant because of thromboembolic problems and were admitted to our department with newly developed anticoagulation associated intracranial hemorrhage (AAICH), and stopped taking medicine due to concern of rebleeding from January 2008 to December 2012. Analysis of the incidence of thromboembolic complications and proper withdrawal time of anticoagulant was performed using the Kaplan-Meier method. Results : Our patients showed high risk for thromboembolic complication. The $CHA_2DS_2$-VASc score ranged from two to five. Thromboembolic complication occurred in eight (42.1%) out of 19 patients without restarting anticoagulant since the initial hemorrhage. Among them, three patients (37.5%) died from direct thromboembolic complications. Mean time to outbreak of thromboembolic complication was $21.38{\pm}14.89$ days (range, 8-56 days). The probability of thromboembolic complications at 7, 14, and 30 days since cessation of anticoagulation was 0.00, 10.53, and 38.49%, respectively. Conclusion : Short term discontinuance of anticoagulant within seven days in patients with AAICH who are at high embolic risk ($CHA_2DS_2$-VASc score >2) appears to be relatively safe in Korean people. However, prolonged cessation (more than seven days) may result in increased incidence of catastrophic thromboembolic complications.

배경: 다제내성 결핵환자에서 이차약제로 구성된 처방 복약시 특히 PAS는 심한 위장장애 등의 부작용으로 환자의 치료순응도 저하에 중요한 요인이 되므로 균음전 후 PAS를 처방에서 제외한 경우의 치료경과 특히, 치료종결 후 재발율에 대한 조사를 통해 치료경과 중에 적절한 시점에 처방에서 PAS제외 가능성에 대하여 평가하고자 하였다. 방법: 2000년 1월 1일부터 2001년 12월 31일 동안에 국립마산결핵병원에서 입원 혹은 외래치료를 받았던 452명의 다제내성 결핵환자 중에서 처방에 PAS가 포함된 194명 중 심한 위장장애 등의 부작용 때문에 PAS를 중단한 환자 중 균음전 후 PAS를 제외한 처방을 12개월 이상 유지할 수 있었던 42명을 대상으로 임상적 특성 및 치료종결 후 재발율을 분석하였다. 결과: 대상환자의 남녀성비는 2.5:1, 평균나이는 56.2세였다. 1.2회의 과거치료력이 있었으며, 사용한 약제는 평균 3.9제였다. 내성약제수는 평균 4.3제였으며 처방에 포함된 감수성약제수는 평균 3.9제였다. 치료가 시작된 후 균음전시기는 평균 2.3개월째였으며, PAS 중단 시기는 균음전 후 평균 6개월째였다. 31.6개월의 추구관찰 기간 중 재발환자는 없었다. 결론: 새로운 항결핵제의 개발이 요원하고, 다제내성 결핵에 사용가능한 약제가 제한된 현 상황에서 치료순응도 개선방안을 강구하는 것은 치료효율을 높일 수 있는 최선의 방법 중 하나라고 생각되며, 다제내성 결핵환자에서 PAS가 포함된 처방으로 균음전이 되고 환자가 PAS복약에 따른 부작용을 호소하여 치료순응도가 나빠질 것으로 염려가 되면 균음전 후 6개월 즈음에는 PAS를 처방에서 제외할 수 있을 것으로 판단되었다.

This research is to classify psychological risk perceptions in purchases process at counterfeit at fashion luxury brands, into a risk perception on purchase activity itself and a risk perception on the post-purchase situation, and to analyze types and characteristics at risk reduction behaviors to reduce each risk perception. In this research a qualitative method was employed, and research-related data were collected and analyzed through in-depth interviews. Results were shown that risk reduction behaviors at psychological risk perception on purchase activity itself included rationalization of purchase, accompanied purchase, reduction and discontinuance of purchase, and that risk reduction behaviors of psychological risk perception on the post-purchase situation included information search, establishment of selection criteria, establishment of marginal limit, selective purchase, planned and compared purchase, and reduction and discontinuance of purchase. Previous researches suggested brand loyalty, selection of famous brands, utilization of information agents by marketers, pre-purchase usage and guaranteed purchase, but these risk reduction methods were not utilized, this probably being interpreted as a result of characteristics of counterfeit. In addition, risk reduction behavior of one type tended to reduce risk perception of several other types, and risk reduction behaviors of various types were utilized to reduce a certain type's risk perception. Not only types of risk perception but also levels of risk perception appeared to have exerted influence to risk reduction behaviors.

As an empirical study on the psychological side effects of using Social Networking Services (SNS), this study aims to identify the reality of negative emotion of using SNS and to predict its consequences. To this end, a measurement tool was developed through literature review, in-depth interview with users and expert review to induce negative emotional factors that can arise while using SNS. An exploratory factor analysis was performed for a total of 24 measurement items, which then were divided into the following 6 factors: 'concern over privacy,' 'burden from undesired connection,' 'relative deprivation,' 'a sense of alienation,' 'concern over reputation' and 'negative feeling about simple relationship.' Also, the relationship between the 6 negative emotional factors and psychological dissonance was analyzed. The results indicate that all the factors, except relative deprivation and a sense of alienation, affect psychological dissonance. It was also found that psychological dissonance, which implies a conflicting condition from using SNS, significantly affects the behavior that possibly reduces and limits the use of SNS. In other words, the users who have experienced psychological dissonance respond passively by avoiding the use of SNS to resolve the dissonance. The results of this study provide the base for explaining the psychological side effects of using SNS, which have been understood at a phenomenal level, such as 'Facebook depression' or 'SNS stress.' In addition, this study is of significance as it helps understand the psychological mechanism by identifying the relationship between negative emotion and use behavior with the theory of cognitive dissonance.

This exploratory study investigated Chinese consumers' perceived usefulness and risks of fashion apps and identified reasons for continuance and discontinuance intentions. This study conducted focus group interviews with a convenience sample of 13 Chinese students majoring in fashion in Korea. Based on interviewee responses, this study identified five attributes leading the perceived usefulness of mobile fashion apps (ubiquity and convenience, multi-media information, personalization, interactivity between consumers, and immediateness) and sub elements related to the five attributes. Five types of perceived risk (privacy risk, security risk, product risk, loss of future opportunity, and time risk) were identified in relation to Chinese consumers' use of fashion apps. The important role of live streaming services was uniquely identified by Chinese fashion app users. Usefulness of location-based information provided by mobile fashion apps were differently perceived according to respondents' use purpose, and augmented reality services provided by the apps were related to entertainment rather than usefulness. This study provides meaningful insights into Chinese consumers' perceptions of fashion apps and important app attributes that influence their continuance and discontinuance intentions. The findings from this study lend preliminary implications for future researchers and fashion businesses interested in the Chinese app market.
