Since its introduction to Korea from Japan at the beginning of the seventeenth century, tobacco became very popular with an amazing rapidity among Koreans. Along with widespread cultivation of tobacco, smoking also became very popular among Koreans, regardless of their classes, ages, and sexes. On the other hand, other imported crops from America via Europe in the sam period, like sweet potato, potato, corn and tomato, did not enjoy such popularity in Korea. A long time after their introduction, Koreans began to cultivate these crops. Why did Koreans respond enthusiastically to the newly-imported tobacco? What kind of factors contributed to the rapid transmission of tobacco in Korea? This study examined the causes of rapid diffusion of the smoking population in three aspects. First was economic aspect. The farming of tobacco yielded a profit by selling it to Chinese. The climate and the soil of Korea fit for farming of tobacco. So the farm land of tobacco expanded gradually since the 18th century. Second was medical aspect. At first, many Koreans believed that smoking was helpful to digestion, expectoration, protecting coldness, and exterminating parasites. Afterwards, they believed smoking could encourage vitality and protect diseases. There was no reason of smoking cessation for the people's health in that the hazards of smoking were not well known to the commonage in those days, though a few intellectuals acknowledge its harm. Third was sociocultural aspect. We could trace the smoking culture of Chosun dynasty through arts, poems, and essays. The making of smoking culture made stable reproduction of smokers generation by generation. Especially, the smoking culture secured juvenile's smoking. Considering the three aspects above, we know that what reason the Decree of Ban of Smoking in Korea was not strict in comparison to that of China (Qing Dynasty), in which the violators were executed. The regulation of smoking by the government failed except controlling in sociocultural aspect. The government reinforced controlling of smoking culture in counteraction to the threat of collapse of the hierarchy of Chosun dynasty in 18th century.

Post-intubation tracheal stenosis was a late time complication after tracheotomy but the happening of dyspnea was unusual. Diagnosing tracheal stenosis after incubation, and figuring out the location and causes of the stenosis were important. Treatment of post-incubation tracheal stenosis relied on accurate diagnosis of the type of tracheal stenosis. Computed tomography (CT) and laryngoscope could be used for detecting the stenosis but not enough. Two patients who were already under the urgent tracheotomy over 1 year were reported. However apnea was found on these two patients for a long time after traheotomy. Obviously laryngeal obstruction appeared. CT virtual bronchoscope and laryngoscope examination showed that the cannula was obstructed and plenty of granulation tissue blocked the orificium. But the exact location of the cannula and the adjacent relationship of the tissue around the cannula was equivocal. Mimics 10.01 software was used to analyze the data of the CT scan and found that a pseudo cavity was formed by granulation tissue which partly blocked the cannula in 1 case; granulation tissue occupation and scar formation in the trachea were the reason of tracheal stenosis but not the collapse of the cartilage in case 2. The purpose of this report is to discuss the cause of dyspnea after emergency tracheotomy, its diagnostic method and their management. CT virtual bronchoscope and laryngoscope should be used as a regular examination after tracheotomy to clarify the location of cannula and avoid the failure of airway opening caused by the dislocation of cannula and the complication. Trachea tissue should be protected properly during and after the tracheotomy which might decline the rate of the tissue remodeling, tracheal stenosis and dyspnea after surgery. The clinical use of Mimics 10.01 made it possible to observe morphology more directly by invasive examination and provided a significant clue to make the operation plan so that it should be used widely. Meanwhile, the method to put the cannula into its right way under the guidance of rigid endoscope and the excision of granulation tissue by semiconductor laser should become one of the best treatments of this disease. Following the method above, laryngeal obstruction was relieved after the surgery. Postoperative follow-up lasted for 1 year and recurrence was not found.

Critical Care Ultrasound(CCUS)is the one of the ultrasound technologies which integrates the bedside ultrasound application into daily clinical practice in critical care medicine. It has multiple roles, at first is a non-invasive monitoring tool to measure variables that can reflect the essence of the disease, and then is a comprehensive visualized tool to evaluate the pathophysiological status and structural changes of organs, which facilitates the critical care providers to know more about the patients and provides more reliable evidence to promote the accuracy and efficiency of the diagnosis, the clinical decision-making and the treatment of the critically ill. Therefore, the critical care ultrasound has been used as one of the core technologies of critical care. The characteristics and advantages of CCUS destine it as an orientation and instruction of visualized diagnosis and treatment. We devote ourselves to explore methods of integrating the application of CCUS into clinical management of critically ill, and establish specific approaches and workflows to standardize the clinical practice of clinicians and reduce medical errors. Therefore, a new diagnostic and treatment pattern can be developed, which is called visualized critical care. It is a care pattern of critical illness based on the CCUS visualization evidence including the pathophysiological status and other informations. This article will carefully discuss the connotation of CCUS, the unique clinical value in critically ill patients, and the value of visualized critical care approaches in acute respiratory and circulatory collapse and shock management, etc..
