Drug-eluting stent (DES) implatation was the major method of coronary revascularization and marked reduction in target-lesion revascularization. Stent thrombosis (ST) is a severe complication that is associated with a high incidence of acute myocardial infarction and death. To prevent ST, dual antiplatelet therapy (DAPT) with aspirin and clopidogrel is recommended for at least 12 months. The premature discontinuation of DAPT is the single most significant predictor of perioperative ST. The risk of surgical bleeding is increased approximately 20% by aspirin or clopidogrel alone, and 50% by DAPT. But the increased risk of perioperative bleeding is not necessarily associated with increased mortality or surgical outcome. Usually, the risk of a cardiovascular event when stopping antiplatelet agents preoperatively is higher than the risk of surgical bleeding when continuing these drugs, except during high risk surgery in a closed space. We remember that DES are never low risk situation for ST and aspirin must never be stopped in all patients with DES. (Korean J Med 2013;85:22-28)

The travel industry in Korea is rapidly shifting according to internal and environmental changes. The growth of travel companies is mainly spearheaded by mergers and acquisitions(M & A). This shift has also led to customers` preference for large-sized travel companies. Among these environmental changes, small- and medium-sized travel agencies are seeking to secure competitive advantage and stable business operation through franchising contracts with large-sized travel companies. The study also has the purpose of presenting important data for the establishment of win-win strategies between franchisors and franchisees, and of suggesting some directions in building long-term relationship mechanisms for franchisors to secure franchisees with high loyalty. The results from the study on the long-term intentionality of travel-business franchising present the following implications: First, this study suggests that six kinds of choice-attribute factors have partially significant influence on relationship quality. Second, the result from the study on the relationship quality and long-term intentionality shows that the bonding factor has significant influence on the intention to continue the relationship. Even though the bonding factor has negative influence on the switching intention, the trust factor does not have significant influence. This implies that in the expansion of franchisees by early travel companies, the franchising-operation policies of franchisors to secure franchisees with high loyalty are consistent with the findings from the study.

The consumer`s behaviour are diversifying at on-line in accordance with the technology of information and communications on the internet based. It is experienced many kind of sector to the information retrieval, shopping and economic activity of buying by internet. This research has been extracted 4 kind of characteristic diagram of interaction, credibility, contents, interest in advance of research and researched that these characteristic diagrams affect the influence for the dependency of community and the intention of buying. Analytical researches, the outcome of the research shows that interaction and credibility of characteristic diagram affected an useful influence for the dependency of community and the intention of buying and then the dependency of community affected an useful influence for the intention of buying. Knowledge which community of source can be affected the intention of buying indirectly, this implies that a men succored by community will be possibility highly to buy since step of exploration in continuous trust.

On After World War II, 16 Grundsätze des Städtabaus was instituted in East Germany in 1950, influenced by socialist realism based on the Soviet Marxist-Leninist ideology. 16 Grundsätze des Städtabaus had the greatest influence on architecture and urban planning in East Germany until it became German. 16 Grundsätze des Städtabaus consist of a total of 16 Principles, and the main content is the definition of cities, city centers, and residences in the socialist ideology, and the rules for the role of the square, transportation, and residential environment. New planned cities according to 16 Grundsätze des Städtabaus were constructed, and buildings in the form of socialist classicism were built. In particular, Plattenbau was supplied to the people as an industrial collective housing form expressing socialist ideology. 16 Grundsätze des Städtabaus was successful as a method of faithfully expressing the socialist ideology, but as a result, it created the limits of urban growth and the inhuman living environment.

N/A Background: Exercise test s (ET), hyperventilation test s (HVT) and cold pressor tests (CPT) have been used t o induce coronary artery spasm. However their diagnostic significance and the circadian variation of exercise test response in patients with vasospastic angina are still uncertain. Methods: To elucidate the circadian variation of ET response and to evaluate the diagnostic significance of non-pharmacological provocation tests, 21 consecutive patients with pure vasospastic angina were studied. Six ETs were performed in the early morning, late morning, and late afternoon in consecutive days, 2 HVTs and 2 CPTs in the early morning. The circadian distribution and types of angina (at rest , on physical activity, or both) from before admission to after discharge (mean follow-up periods 19±9 months) were evaluated by clinical history, clinical records and Holter recordings . Circadian distribution of anginal attacks recorded through the all observation periods were classified into 3 patterns (morning and night : MN, morning and afternoon or evening : M+F/ E, morning, night and afternoon and/ or evening : MN+F/ E). Results: One hundred and eleven ETs (39 early morning, 38 late morning, 34 late afternoon tests), 35 HVTs and 33 CPT s were performed. ETs showed 14 positive responses (36%) in the early morning, 14 (37%) in the late morning and 12 (35%) in the late afternoon without any circadian variation. Among the 11 patients who underwent all 6 exercise tests, 3 patients (27%) showed at least one positive response in the early morning, 4 (36%) in the late morning and 4 (36%) in the late afternoon. Subgroups of the subjects according to the types and activity of angina and the numbers of spastic artery also failed to show any circadian variation in ET response, but M+F/ E group of circadian pattern of angina showed a peak of positive response in the early morning (p <0.05). HVTs showed significantly higher positive response (23/35, 66%, p <0.05) than ETs (14/ 39, 36%) and CPTs showed significantly lower positive response (2/ 33, 6%, p <0.01) than ETs in the early morning. Double test s with more than 1 positive response couldn`t increase the positive response in ETs (9/19, 47%), and CPTs (2/14, 14%) but increased significantly in HVTs (15/16, 94%, p<0.05), particularly in the group with low activity (7/ 8, 86%, p <0.01). ETs showed ST segment elevation in 29 (72%) and depression in 11 (28%) of the 40 positive tests, HVTs in 21 (91%) and 2 (9%) of the 23 positive tests and CPTs in 2 (100%) and 0 (0%) of the 2 positive tests. The ST segment elevation was significantly higher in HVTs than in ET (p <0.05). Conclusion: These findings suggest that the exercise test in the early morning do not increase positive response and is not a sensitive diagnostic test associated with occasional depression of ST segment , but hyperventilation test , especially if repeated, is a very sensitive test with predominant elevation of ST segment in patients with vasospastic angina.(Korean J Med 60:358- 367, 2001)

Korean hemorrhage fever(KHF) is an acute febrile disease with high fever, hypotension, gastrointestinal symptom, hemorrhagic symptom and renal failure. An adult patient with KHF presented with normal EKG on admission and no hypotensive period, subsequently developed dypnea on 10 th hospital days. Pulmonary edema pattern of the chest x-ray, T inversion of EKG and diffuse ventricular dyskinesia of echocardiography apperaed on 10th hospital days, and then disappered on 2 month. We experienced a rare case of KHF associtaed with myocarditis. This case suggests that the Myocarditis can be associated with KHF.
