A rare case of broncholithiasis was reported, and briefly reviewed. A 44 year-old woman, showing the symptoms of hemoptysis. frequent attacks of fever,coughing and roentgenologically typical middle lobe syndrome, was surgically treated with resection. The removed lung showed typical middle lobe syndrome by broncholithiasis.

In order to investigate the biological properties, pathogenicity and immune responses in artficially infected SPF chickens with Avian infectious bronchitis virus that was isolated from chickens showing IB like signs in southern region of Chung buk. Results obtained throuth the experiments are summarized as follows. 1. From 15 IB suspected cases, two strains of IB virus were isolated, one each from the tracheas and lungs. 2. Infectious bronchitis specific embryo lesions were observed after four serial passages of the isolates in chicken embryos. 3. The field isolates and M-41 strain of IB virus interfered with the replication of Newcastle disease virus in chicken embryos. 4. When specific pathogen free chickens, two week old, were inoculated with the IB virus isolates, clinical respiratory signs as dyspnea, coughing were observed. Airsacculitis was observed by necropsy. 5. AGP antibody positive rates of inoculated SPF chickens were highest on day 14 and lowest on day 36, while HI antibody responses were detected on day 14 in all Groups, the reinoculated Group was shown highest titers. 6. By Indirect immunofluorescence antibody assay of artificially infected SPF chickens, the viral antigens were detected in tissues of larynx, trachea and lung on the 4 th to 7 th days post inoculation.

Worldwide, the number of corona virus disease 2019 (COVID-19) confirmed cases is rapidly increasing. Although vaccines and treatments for COVID-19 are being developed, the disease is unlikely to disappear completely. By attaching a smart sensor to the respirator worn by medical staff, Internet of Things (IoT) technology and artificial intelligence (AI) technology can be used to automatically detect the medical staff's infection symptoms. In the case of medical staff showing symptoms of the disease, appropriate medical treatment can be provided to protect the staff from the greater risk. In this study, we design and develop a system that detects cough, a typical symptom of respiratory infectious diseases, by applying IoT technology and artificial technology to respiratory protection. Because the cough sound is distorted within the respirator, it is difficult to guarantee accuracy in the AI model learned from the general cough sound. Therefore, coughing and non-coughing sounds were recorded using a sensor attached to a respirator, and AI models were trained and performance evaluated with this data. Mel-spectrogram conversion method was used to efficiently classify sound data, and the developed cough recognition system had a sensitivity of 95.12% and a specificity of 100%, and an overall accuracy of 97.94%.

돼지는 꿀꿀거림, 기침, 비명과 같은 다양한 소리로 환경에 대한 반응과 건강 상태를 나타낸다. 돼지 음성의 중요성으로 최근 들어 돼지의 음성은 축산업 종사자에게 매우 중요한 데이터로 활발하게 연구되고 있다. 이를 위해 돼지의 음성 패턴을 분석하여 농장 소음 속에서 돼지의 음성을 구분하고 음성과 기침 소리를 구분하는 경량화 MobileNet 모델을 제안한다. 이 MobileNet은 돈사 내에서 다양한 배경 잡음, 기침 소리 등의 다양한 소리 속에서 돼지의 음성만을 정밀하게 구분하고 분석할 수 있었다. 테스트 결과, 이 모델은 98.2%의 높은 정확도를 보여주었다. 이러한 결과를 바탕으로 향후 연구에서는 돼지의 감정 분석, 스트레스 파악 등의 문제 해결을 기대한다.

1. Objectives This study is purposed to classify deficiency syndrome(虛證) and Excess syndrome(實證) of chief lung-disorder diseases. 2. Methods It was researched on the comparative and literal study about the relation to Yeong-Chu Gyeong-maek Chapter (${\ulcorner}$靈樞 經脈編${\Ircorner}$) and Dongui-Bogam (${\ulcorner}$東醫寶鑑${\Ircorner}$) and Dongui-Susebowon (${\ulcorner}$東醫壽世保元${\Ircorner}$) in chief lung-disorder symptoms or diseases. 3. Results and Conclusions (1) The chief lung-disorder diseases of Yeong-Chu Gyeong-maek Chapter (${\ulcorner}$靈樞 經脈編${\Ircorner}$), Dongui-Bogam (${\ulcorner}$東醫寶鑑${\Ircorner}$) and Dongui-Susebowon (${\ulcorner}$東醫壽世保元${\Ircorner}$) are asthma(喘), coughing(咳), fullness in the chest(胸滿), sweating symptoms(汗出), cold-heat symptoms(寒熱), dysphoria(煩躁) and sneezing. (2) Asthma symptom(喘) was shown to Soeumin's 4 exterior deficiency diseases, Taeumin's 1 exterior deficiency disease and 1 interior excess disease, and Soyangin's 1 interior excess disease. (3) Coughing symptom(咳) was shown to Soeumin's 1 extrerior deficiency disease and Taeumin's 1 interior excess disease. (4) Fullness in the chest(胸滿) was shown co Soyangin's 4 exterior excess diseases. (5) Sweating symptoms(汗出) was shown to Soeumin's 10 exterior deficiency diseases, Taeumins's 1 exterior deficiency disease, and Soyangin's 1 exterior defecieny disease. (6) Cold-heat symptoms(寒熱) was shown to Soyangin's 4 exterior excess diseases. (7) Dysphoria(煩躁) was shown co Soeumin's 1 exterior deficiency disease and 8 interior deficiency diseases, Taeumin's 1 interior excess disease, and Soyangin's 4 exterior excess and interior excess diseases. (8) Sneezing symptom was shown to Taeumin's 1 exterior excess disease.

Diaphragmatic eventration is a rare condition in primary diaphragmatic diseases and is found rarely in clinical experience. Diaphragmatic eventration means abnormally high position of diaphragm, which is caused acquired, paralytic or congenital, nonparalytic etiologic origins. This report is presented a symptomatic diaphragmatic eventration of 50 years old woman, who had complained coughing and left chest pain since I year ago prior to admission in Kosin Medical College, Gospel Hospital. A patient who had established accurate diagnosis at pre-operative period. There had been post-operative course uneventfully.

The hamartoma is the commonest benign tumor of the lung and proved incidentally as asymptomatic coin lesion on routine chest radiologic examination, but has very low incidence, especially in endobronchial origin. The authors experienced a case of coincidental with intrapulmonary and endobronchial hamartoma. The patient, a 60-year-old man, a farmer, was admitted due to coughing and fever. Preoperative diagnosis was achieved by flexible bronchoscopic biopsy and managed by right middle lobectomy. Three lobulated masses were palpable in the right middle lobe. He was discharged on 15th postoperative day, without problem.

Embryonal carcinoma of the mediastinum is a very uncommon disease. This is a report of an embryonal carcinoma in the mediastinum found in a 25 years old Korean male patient who had been suffering from chest pain and intractable coughing for 6 months. 5 weeks prior to this admission hemoptysis and high fever were followed. Right exploratory thoracotomy was performed under the impression of a mediastinal tumor, but found to be unresectable. Irradiation therapy was tried, but no response was observed. Patient expired on 78th day postoperatively.

Acquired communicated fistula between the esophagus and respiratory system are infrequent and they are caused by carcinoma, trauma, infection and traction. This report reviews the feature of acquired esophagobronchial fistula[that developed spontaneously]. Patient is 34 year old man with excellent result by surgical intervention. The surgical procedures consist of division and repair of the fistula. Clinically and radiologically, the patient is free from coughing after drinking, substernal distress, esophagorespiratory fistula, and esophageal stricture after surgical treatment.
