Since the inception of the National Tuberculosis Control Program in 1962, the incidence of tuberculosis and its associated mortality has declined dramatically due to effective anti-tuberculosis drugs and a systematic control program. The prevalence of radiographically active tuberculosis has fallen from 5.1% in 1965 to 1.0% in 1995. However, tuberculosis is still a major problem, as the mortality rate is still higher compared to other developed countries. Furthermore, tuberculosis is currently re-emerging in HIV/AIDS epidemic countries. In order to lower the tuberculosis death rate to the levels of developed countries, the tuberculosis control efforts in private healthcare institutions and the national tuberculosis control program in the public sector, need to work together more effectively and efficiently. In this paper, the quthor reviewed the current situation regarding tuberculosis management in private healthcare institutions of Korea based on the literature and the National Health Insurance Claim data, and the future tasks of tuberculosis management are suggested.

Endobronchial metastasis of leiomyosarcoma is rare, but it can cause life-threatening complications, such as massive hemoptysis, respiratory failure or even death. The development of new endoscopic modalities allows for effective endobronchial management. We report three patients with endobronchial metastases from advanced leiomyosarcomas which caused bronchial obstruction. The bronchoscopic examinations revealed masses obstructing the left main bronchus in all three patients. After removing the endobronchial tumor via interventional bronchoscopy, there was symptomatic and radiologic improvement. Moreover, the patients were able to undergo additional palliative chemotherapy. Therefore, endobronchial management of endobronchial tumors should be considered in the treatment of endobronchial metastasis, even in patients with advanced malignancies.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease caused by the degeneration of upper and lower motor neurons. The disorder causes muscle weakness and atrophy in airway muscles including pharyngeal, laryngeal and other respiratory muscles. The response to muscle realxant is also altered in patients with ALS. Because of the inherent muscle weakness and associated respiratory insufficiency, particular attentions are needed in anesthetic management of ALS patients. We used proper doses of inhalation anesthetics and opioids under EEG-entropy (electroencephalography-entropy)-monitoring without the use of muscle realxants in the anesthetic management of a patient with ALS. The patient early recovered and was discharged on the same day without any respiratory complications.

This study was carried out to investigate the epidemiological prevalence of diseases from birth to weaning in 66 dairy calves which were delivered from three stock farm in Chonbuk area. We examined body weight gain, incidence rate of diseases and population mortality rate in relation to age, season, environmental temperature and rearing management conditions for one year. The results of this experiment were as follows: Birth weight of dairy calves born of primiparae was lower than those of multiparae. But no significant difference in body weight gain was observable between dairy calves born of primiparae and those of multiparae. Body weight gain of diseased calves was lower than normal calves. Of 66 delivered calves, 34 calves(51.5%) were affected with gastronitestinal and/or respiratory diseases. The prevalence of the diseases were gastrointestinal disease(28.7%), respiratory disease(18.2%), and gastronitestinal and respiratory disease(4.6%). The gastronitestinal disease was occurred contrinually regardless of the season. Whereas all of the respiratory disease were occurred in winter and a change of season(December to April). 68.4% of the gastronitestinal disease, and all of the respiratory disease were occurred at atmospheric temperatures below 1$0^{\circ}C$. 89.5% of the gastronitestinal disease were occurred within 3 weeks old, whereas 50% of the respiratory disease were occurred intensively between 3 weeks and 4 weeks old. Of 66 delivered dairy claves, 2 calves were died(3%) with respriratory disease.

Background: Respiratory protection equipment (RPE) is the last resort to control exposure to workplace air pollutants. A comprehensive respiratory protection program (RPP) ensures that RPE is selected, used, and cared properly. Therefore, RPP must be well integrated into the occupational health and safety requirements. In this study, we evaluated the implementation of RPP in Iranian petrochemical industries to identify the required solutions to improve the current status of respiratory protection. Methods: This cross-sectional study was conducted among 24 petrochemical industries in Iran. The survey instrument was a checklist extracted from the Occupational Safety and Health Administration respiratory protection standard. An index, Respiratory Protection Program Index (RPPI), was developed and weighted by analytic hierarchy process to determine the compliance rate (CR) of provided respiratory protection measures with the RPP standard. Data analysis was performed using Excel 2010. Results: The most important element of RPP, according to experts, was respiratory hazard evaluation. The average value of RPPI in the petrochemical plants was $49{\pm}15%$. The highest and lowest of CR among RPP elements were RPE selection and medical evaluation, respectively. Conclusion: None of studied petrochemical industries implemented RPP completely. This can lead to employees' overexposure to hazardous workplace air contaminants. Increasing awareness of employees and employers through training is suggested by this study to improve such conditions.

Lung cancer 환자 중 호흡에 의한 종양의 움직임이 큰 lung lower lobe에서 stetreotactic radiosurgery(SRS)시 호흡 주기 중 종양의 움직임이 적은 호흡 주기에서만 방사선을 조사하기 위해 respiratory gating system을 사용함으로써 그 유용성에 대하여 알아보고자 한다. lung lower lobe의 SRS 환자 2명을 대강으로 하였으며, 환자의 복부에 maker block(sensor)을 부착하고 tracking camera와 real time position management(RPM)를 이용하여 호흡 주기를 측정하면서 1회 호흡주기에서 10 phases의 4D-CT를 촬영 하였다. 종양의 위치 변화가 급격하지 않은 percent($\%$)의 phases를 치료 phases로 결정하였고, 치료 phases의 CT image를 maximum intensity projection(MIP) 기법으로 재구성 후 volume contouring을 하였다. set up 의 재현성 및 GTV의 위치 변화를 확인하기 위해 치료 전과 치료 중 2회의 4D-CT 촬영을 하였다. GTV의 움직임이 가장 큰 Y(longitudinal)축에서 A환자 full($0\%\~90\%$) phases의 9.4mm가 치료 ($30\%\~60\%$) phases 에서는 2.6mm로, B환자 full($0\%\~90\%$) phases의 11.7mm가 치료($30\%\~70\%$) phases 에서는 2.3mm로 줄었다. 2회의 4D-CT 비교 결과 Set up의 X, Y, Z축 오차는 모두 3mm 이내였다. 호흡에 의한 종양의 움직임이 큰 lung lower lobe에서 SRS 시행 시 respiratory gating system의 사용은 종양의 움직임을 5mm 이내로 감소시킬 수 있어 유용하였다.

Objective: In this study, a questionnaire survey was conducted for doctors and patients to obtain basic data necessary for the development of an integrated medical system for idiopathic pulmonary fibrosis (IPF). Methods: Questionnaires were developed separately for doctors and patients through an expert group meeting. The survey subjects were recruited online and offline, and finally, responses from 231 doctors and 59 patients were used for statistical analysis. Results: The most important parts in the treatment of IPF for both doctors and patients were the "improvement of respiratory symptoms," "improvement of quality of life," and "prevention of disease progression." Antifibrotic agents were prescribed at a high rate, and 100% of the specialists in Western medicine (WM) and 45.8% of patients reported experiencing side effects. As for the additional payment costs that patients considered as affordable for an integrated medical system, "under 50,000 won (about 38$)" was reported the most in both doctor and patient groups. With regard to the reasons for their reluctance to recommend an integrated medical system for IPF, specialists in WM responded highly to "uncertain evidence for treatment effectiveness." Regarding complementary and alternative medicine therapies that can be beneficial in patients with IPF, "lifestyle management," "diet management," "herb," "relaxation therapy," and "psychotherapy" were ranked high in both doctor and patient groups. Conclusions: In this study, a questionnaire survey on IPF was conducted to review actual treatment status, analyze shortcomings, and identify considerations for the development of an integrated medical system for IPF in the future.
