  • Syncope in children and adolescents have a common occurrence according for up to 15% before adulthood. Micturition syncope, a kind of situational syncope, can be considered a form of reflex syncope. It can typically occur in healthy young men after rising from bed in the early morning who experience sudden loss of consciousness during or immediately after urination. The mechanism of micturition syncope is not completely understood, but it has been suggested that vasovagal reflex mediated bradycardia and peripheral vasodilation and decreased venous return due to Valsalva effect and standing position lead to the decrease in cerebral blood flow resulting in syncope. The causes of syncope are variable. So complete history taking, physical examination, electrocardiography, exercise stress test, echocardiography, head-up tilt table test, electroencephalography(EEG), brain magnetic resonance image and urodynamic study should be required for the diagnosis of micturition syncope. There were several reports about micturition syncope. However, literature of micturition syncope at the pediatric age has rarely been reported in Korea so far. Therefore, we report a case of a 9-year-old boy with micturition syncope with typical EEG findings of high amplitude delta wave and flattening during syncope.

  • The resource-based view (RBV) explains that the competitive advantage is mainly based on the resources which have strategic characteristics. Therefore, finding, developing and maintaining strategically valuable resources has been one of main research topics and a starting point in the corporate strategy structure in RBV. In this regards, attempts to recognize strategically valuable resources have been one of crucial issues in RBV researches. Especially, Barney's VRIO has been widely used as a practical tool for finding strategically valuable resources. However, empirical studies on VRIO framework's effectiveness have not been sufficiently implemented, and there has been no proven relation among the components of the VRIO so far. This is mainly because the concepts or definitions on core components of the VRIO - Value, Rareness, Inimitability, and Organization - are too comprehensively explained and measurements of each component cannot be easily quantified. Considering these, this paper presents empirical results of the relation between VRIO components and competitive advantage, and tests effectiveness of VRIO Framework with utilizing sufficient technology evaluation cases and financial statements of 2,252 technology based SMEs in Korea. As a result, the components of the VRIO have a positive influence on competitive advantage. The attributes of strategic resources - Value, Rareness, and Inimitability - have a statistically meaningful positive effect on organization, while organization has a positive effect on the competitive advantage serving as a parameter between the attributes of strategic resources and competitive advantage.

  • Today's sports, by themselves, express a wide variety of phenomena and reproduce or imply complex social symbols. The definition of sports being transformed in combination with ideology, which has become a central issue in each era, has become more diverse in recent years. Recently, with the 4th Industrial Revolution leading the social phenomenon, sports culture is producing a new phenomenon. In this era, we need the study in the question of how to understand and interpret sports culture is the right approach. The struggle for survival in each discipline was expressed as a reinterpretation of sports culture. This is to answer questions about how sports culture is consumed, spread and reinterpreted. The purpose of this study is to find out the direction and directing point of sports culture. Based on such problem recognition, five types of answers to what sports culture consumes were presented. Based on this, the fairness related to school sports, sports society-club(sports clubs), sports events, sports media, and sports was suggested as a medium for the spread of sports culture. We are accepting and transforming numerous scientific civilizations to improve sports culture and to promote consumers. However, there is a pity not to define such a thing. Efforts at a more fundamental level, such as cultural regulation and fundamental directions, need to be discussed. The framework of reinterpretation of sports culture should be constantly looking for directions and answers about what to do, not just the level of interpretation.

  • Animation tool has been made changes rapid development of animation from analog tool to digital authoring tool. Depending on the change in the status of digital authoring tools, education of digital authoring tool has brought many changes occurred in the institute and university. Digital authoring tool was insufficient for research of authoring tool due to the recognition that authoring tool is a simple tool. I try to resolve the difficulties through the analysis digital authoring tools to students studying at the university. In addition, Suggests social/cultural change of animation practitioners and effective training methods of digital authoring tools in the education of beginners and practitioners. This tool have perceptual knowledge and narrative knowledge. Since the language features and knowledge features is difficult to learn. it must be learned knowledge of computer graphics of professional level properly to learn. Then users should try to be creative within the authoring tool to produce creative results. also formed the community and to exchange information for self-development further it should form job market that authoring tool make formed through medium. So, I think that there is a need to change academically attitude to authoring tool. because this is not only the positive side but it occurs phenomenon to enslave users in authoring tool, and blind faith in the authoring tool or critical stance on software. It was a lot of pre-existing research that investigate engineering and industrial side in the authoring tool. Through this thesis, We will find social/cultural features and academic significance, and investigate that how to approach the method of education.

  • This study is to exhibit the iconographic narrative and visual culture of ancient Chinese art. The focus of the study is the composite integration of literature and graphic forms, in particular the heterochronous expression of different scenarios of scenes occurring in different time periods in pictures of ancient art. The unity of their origins with picture narration and comic art creation is the fusion of our modern times. The ancient Chinese understanding of visual art includes the traditional style of images and their symbolic meanings. Among artistic narrative expression, imagery contemplation and visual presentation have significance. Artistic thinking is inseparable from visual articulation. It is a rational thought process through creative language interpretation in visual media of imagery narratives. The characteristics of ancient imagery thinking and the way of presenting sequential incidents in the form pictures is a creative space of time. This is the spatial thinking of modern comic art, which is demonstrated through acceptance in artistic styles. Image narration needs new forms and media styles, including integrating with cultural values as aesthetic communication is necessary.

  • Background: Vitamin C is an essential nutrient, taken as a daily supplement by many people. Recently, high-dose vitamin C is considered as a therapeutic regimen in some clinical situations. Until now, few studies have been done with the effects of high-dose vitamin C on the immune response. Methods: In this experiment, the effects of high-dose vitamin C on cell-mediated immune response in immunologically competent mice were evaluated. After intraperitoneal injection of 2.5, 5, or 10 mg/day of vitamin C for 10 days, delayed type hypersensitivity (DTH) was provoked against DNFB in the pinnae as a model for cell-mediated immune response. Severity of DTH reaction was evaluated as the thickness of pinnae, and the vitamin C levels were measured in the serum, liver, kidney, lung, pinnae, and splenocytes. Results: After challenge, the thickness increased at its peak on the $2^{nd}$ day in all groups. On the first day, the pinnae were thicker in the injected groups than in the control. On the contrary, the increment of the pinnae thickness was attenuated and the number of cells infiltrated in the site of DTH decreased proportionately to the amount of vitamin C administered from the second day on. With vitamin C exogenously given, the serum level peaked at 30 min after injection, and returned abruptly to its basal level without accumulation. However, it accumulated in the liver, kidney, and especially in the pinnae inflamed and splenopcytes, proportionately to the amount administered. Conclusion: Based on these results, it is suggested that, in one hand, exogenously administered high-dose vitamin C accumulated in the splenocytes and presumably changed the function of them resulting in the augmented cell-mediated immune response, as was revealed in the first day of DTH reaction. On the other hand, it seems likely that the vitamin C also showed anti-inflammatory effects.

  • Though adolescents have the skillful ability to use internet and use it extensively, they have experienced sexually less than adults and are hard to have the right viewpoint toward sexuality. Because of these adolescents' characteristics, internet pornography cause them serious troubles with their sexual behavior. Based on the viewpoint, this research explores structural relationship among their sexual orientations, exposure to internet pornography, the sexual drive and behavior with PLS path modeling analysis. In result, androcentric and pornography-friendly sexual orientation have an influence on the exposure to internet pornography, in turn, the exposure to internet pornography affect the sexual drive and behavior directly and sexual behavior indirectly mediated by the drive. The significance of this research is to identify fact that sexual orientations, reconceptionalized from previous researches's dependent variables, predict the exposure to internet pro-pornographic and is to identify a popular myth indirectly that the exposure to internet pornography stimulates sexual drive to cause behavior, in turn leads to sex crimes finally.

  • This study was carried out to examine the converging factors related to academic burnout in students from health-related majors who are involved in studying for the Test of English for International Communication (TOEIC). Research subjects included 291 randomly selected students from the J-region, who were enrolled in TOEIC classes. Data collection took place from April 3, 2017 to April 14, 2017, using anonymous self-administered questionnaires. The results of a multiple regression analysis in female students showed higher academic burnout pertaining to studying for the TOEIC when sleeping hours, self-worth, self-efficacy, school adaptation resilience, and study immersion were low, and job-seeking stress and test anxiety were high. The explanatory power of this model was 65%. Based on these results, to reduce academic burnout pertaining to studying for the TOEIC in health majors, it is first necessary to increase sleeping hours, self-worth, self-efficacy, school adaptation resilience, and study immersion, and to make efforts to manage self-competence, job-seeking stress, and test anxiety. The results of this study may be used to decrease the academic burnout caused by studying for the TOEIC in health major students and to increase their aptitude for studying English, to cultivate globalized capabilities. Future studies need to conduct an effect analysis on the control and mediation effect that these factors have on academic burnout.
