Contrast media are substances that are used to enhance the contrast of structures or fluids within the body in medical imaging. Those are commonly used to enhance the visibility of blood vessels and the gastrointestinal tract. The aim of this study is to evaluate patients who got injected iopamidol, developed as one of contrast medium regarding changes in cardiovascular system and especially, adverse drug reactions. This study were performed on randomly selected a total of 51 patients (range of 15~85 years old) who got injected contrast medium, Iopamidol at a P hospital in Gyeonggi province from September 22nd, 2008 to January 24th, 2009. Data were collected by questionnaire though person to person. We analyzed the data by SPSS (Version 12. for windows). Methods of analysis were frequency and cross analysis. In results, 19.6% (n=10) were founded for adverse drug reactions of contrast medium. 25.0% (n=4) of 10 patients who had adverse drug reactions of contrast medium had took abdomen contrast test. 2 patients of those took contrast test for chest. Also, 3.9% (n=2) patients felt vomiting and nausea after injection of contrast medium. In conclusion, 19.6% patients experienced adverse drug reaction of contrast medium. Therefore, when taking radiation test, we should make efforts to minimize adverse drug reactions to achieve suitable and effective treatment.

This paper studied the effects of service quality and system quality that affect customer’s satisfaction and continued usage intention regarding mobile network conditions. The hypotheses and research models were completed using research factors of service quality(reactivity, empathy) and system quality(connectivity, ease of use, channel-mobility) borrowed from previous studies on DMB and IPTV. The hypotheses and research models were verified through experiments and surveys. The key finding showed that customer’s expectation on service quality and system quality under fast network(Wifi) was higher than that of under slow network(3G). Furthermore, it showed that users react more sensitive to service quality than to system quality such as network speed. Based on the results, this study has the implication for expanding the understanding of the factors used in previous DMB and IPTV studies by applying them in N-screen domain.

A big success of the 3D film ‘Avatar’ in 2009 opened a full-fledged 3D movie era. A new industrial possibility of 3D contents was predicted in Korea and then the support for 3D contents production took placed via various media platforms. Korean government also announced the new development policies with a focus on 3D content. However, the 3D content industry has not been activated. Therefore, in this study by applying AHP(Analytic Hierarchy Process) method we tried to grasp the reason of the deactivation of 3D content industry through analyzing the relative importance rate of three research factors(content aspects, technical aspects, and policy aspects) that were mainly considered to activate the industry. The results of this study showed that the relative importance rate of content aspects was higher than that of technical aspects and policy aspects. It means the lack of 3D contents is one of main reason causing the delay of 3D industrial activation. And it also showed that the relief of human factors such as visual fatigue evaluated as a sub-factors of technical aspects are challenges to be solved soon..

A total of 500 sera and lungs of slaughtered pigs were examined to investigate antibody titer, prevalence of pulmonary lesion, and interrelation among lung lesion score, type of pulmonary lesion and antibody titers by ELISA. The results obtained were as follows; 1. The highest distribution of antibody titer was showed at 20 - 80 in M hyopneumoniae, 160 - 640 in P multocida type A and 160 - 640 in A pleuropneumoniae serotype 2 and 5. 2. The prevalence of pulmonary lesions was 84.0%, mean pulmonary lesion and mean lung score listed as 24.0±19.8% and 2.5± 1.6, respectively. 3. In the prevalence of type of pulmonary lesion, enzootic pneumonia, pleuropneumonia and pleuritis were 58.2%, 10.0% and 15.8%, respectively. 4. Lung lesion score and type of pulmonary lesion were not interrelated with the distribution of antibody titer to specific pathogens, and causative pathogens of respiratory diseases were complicated with various bacteria.

This study is to derive the factors that influence the acceptance of LTE smart phones. Using an extended technology acceptance model to look at the factors affecting the acceptance LTE smart phone. Variables and the LTE features on the personal characteristics variables were chosen based on the study. This study was done through a survey. Surveyed LTE smart phones primary audience, taking into account the age of 20 were analyzed mainly. LTE smart phones acceptance factors affecting individual innovation, speed, price factors. When formulating marketing strategies in the future, based on the results of this study, elements that can stimulate innovation and speed, not just an individuals stability, if we estimate that we can derive a more meaningful and effective marketing results.
