Amiodarone is an effective antiarrhythmic agent because of its vasodilator actions. Nowadays it is mostly used to treat patients with severe cardiomyopathy or coronary artery disease complicated by disturbances in the supraventricular or ventricular rhythm. But, some doctors are reluctant to prescribe it because of its many side effects. These include impairment of liver and thyroid fuction and, rarely, damage to the lungs. Most of all, its most serious side effect is amiodarone-induced pulmonary toxicity, which can occur in up to 10% of patients, with mortality rates as high as 50%. We recently experienced one case of the patient with the Amiodarone-induced pulmonary toxicity. The clinical manifestations of the patient was cough, painful breathing, fever, presence of rales, decreased breath sounds, and sputum. We report the change of the patient's symptoms through both western medical treatment and oriental medical treatment.

Dirofilariasis is a mosquito-borne parasitic infection that mainly causes symptoms such as chronic cough, respiratory distress, abnormal breath sounds, heart valve dysfunction, right heart hypertrophy, liver congestion and cirrhosis, ascites, and pleural effusion in dogs. In this study, from June to September 2021, we collected and identified mosquitoes in parks where citizens often take their dogs for a walk, and created pools from them by month, species, and location. These pools were checked for the infection of Dirofilaria immitis by PCR and the minimum infection rates (MIRs) were calculated. The MIR of all mosquitoes collected was 6.4, and the MIRs of mosquitoes from Daewangam Park, Yeocheoncheon Walk, Taehwagang National Garden, and Sinbulsan County Park were 9.7, 4.7, 2.1, and 0, respectively. It also confirmed that Aedes hatorii, Aedes vexans nipponii, and Ochlerotatus koreicus were major vectors of heartworm in Ulsan. Our results suggest that heartworm prophylaxis should be considered in Ulsan.

Korean standard poetry with a fixed form are Rated Sijo. These Rated Sijos can be found in the 24 number of Gosijos. Then, why should Korean standard poetry be Rated Sijo? This is because only the Rated Sijo has a fixed form frame. Rated Sijo naturally tailored by a rigid framework is the best representation of Koreans' unique breath and temperament. Also, Rated Sijo is superior to general sijo or poem in terms of literary therapeutic utility for human body. If Haiku omits the end of narrative with the rated number of sounds and invites different imaginations to each reader, the Rated Sijo presents a certain frame to the direction of the human's rated signal by constructing the essence of the narrative with the rated number of sounds. Thus, the Rated Sijo suggests the way of human harmony and communication by inducing different imagination of readers cooperating in a certain direction. So, the famous poem of Korea, Rated Sijo, presents our future as a framework of literature that can contribute to the improvement of human communication and quality of life. Therefore, research to preserve and develop the value of the Rated Sijo should now be initiated and continued.

We have experienced 2 cases of the hunshot wound sof the chest involving cardiac injuries at department of the thoracic surgery, Capital Armed Forces General Hospital during I year from April I 1979 to Jan. 1980. In one case of two patients , he was a 22 years old man who was transported to this emergency room 4 hour 10 minutes after having gunshot wound of the left chest by helicopter. Physical examination showed small inlet in left 3rd ICS and left parasternal border, large outlet in left 8th ICS and left scapular line, no breath sound on left side and distant heart sound. chest roentgenography demonstrated marked pleural effusion in left side and mediastinum shifted to right. As soon as chest X-ray was taken, the bleeding through penetrating wound became profuse and cardiac arrest ensued. Closed chest cardiac massage was started and vigorous transfusion continued, but no effective cardiac activity could not be obtained. The patient was pronounced dead due to exsanguinating hemorrhage from wuwpected cardiac wounds. In this critically injured patient with evidence of intrathoracic hemorrhage and suspected cardiac penetration, only emergency thoracic exploration and immediate surgical control of bleeding points might offer the maximum possibility of survival. The other case was a 23 years old man who was transferred to the emergency room 4 hours 50 minutes after having kmultiple communicated fractures of sternum and linear fracture of right mandible by a missile. Examination revealed about 30% skin loss of the anterior chest wall, weak pulse of 96 beats/min., distant heart sound and decreased breath sounds bilaterally. finding on the chest X-ray films showed multiple sternal fractures, marked pericardial effusion indicating hemopericardium. So, the patient was moved immediately to the operation room where, after endotracheal tube inserted, a median sternotomy was performced. A hemorrhagic congestion of the right upper lobe and marked bulging pericardium were disclosed. The pericardium was opened anterior to right phrenic nerve and exsanguinating hemorrhage ensued from the 0.5cm lacerated wound in the auricle of right atrium. The rupture site of right atrium was occluded with non-crushing vascular clamps and then was over sewn with interrupted sutures. It was thought to be highly possible that he was alive long enough to have cardiorrhaphy because of cardiac tamponade, which prevented exsanguinating hemorrhage. He was taken closed reduction for linear fracture of right mandible 2 weeks after repair of ruptured right auricle in dental clinic. This patient's post-operative course was not eventful.

Sleep apnea causes various secondary disease such as hypertension, stroke, myocardial infarction, depression and cognitive impairment. Early detection and continuous management of sleep apnea are urgently needed since it causes cardio-cerebrovascular diseases. In this study, wearable device for monitoring respiration during sleep using PVDF film was developed to detect vibration through trachea caused by breathing, which determines normal breathing and sleep apnea. Variables such as respiration rate and apnea were extracted based on the detected breathing sound data, and a noise reduction algorithm was established to minimize the effect even when there is a noise signal. In addition, it was confirmed that irregular breathing patterns can be analyzed by establishing a moving threshold algorithm. The results show that the accuracy of the respiratory rate from the developed device was 98.7% comparing with the polysomnogrphy result. Accuracy of detection for sleep apnea event was 92.6% and that of the sleep apnea duration was 94.0%. The results of this study will be of great help to the management of sleep disorders and confirmation of treatment by commercialization of wearable devices that can monitor sleep information easily and accurately at home during daily life and confirm the progress of treatment.

Owing to the latest development of component and media processing technologies, UHDTV as a successor of the HDTV is expected that this will be coming soon realization. Accordingly, an audio technology that provides a 5.1-channel surround sound in home should be contemplating on what services should be provided with the advent of UHDTV era. In fact, however, the market of 5.1-channel audio is struggling, due to the difficulty of installation and maintenance of the multi speakers in a home. Meanwhile, the movie sound market for a long time been used in 5.1 and 7.1-channel sound formats, have changed as Dolby ATMOS, IOSONO, AURO3D etc. are launched one after another with the introduction of hybrid audio technologies that include the ceiling and object-based sounds. This very object-based audio technology is assured to be introduced in the home theater and broadcast audio market, and this change in audio technology is expected to be a breath of pioneering technological advances and market growth from the channel-based audio market that lacks flexibility. In this paper, we will investigate a suitable realistic audio solution for UHDTV, and introduce hybrid audio technologies, which is expected to be an audio technology for UHDTV, and we will describe the hybrid audio content format and reproduction methods in a home and consider the future prospects of realistic audio.

A 47-year-old-man was admitted to the emergency department with dyspnea, right pleuritic pain, and high fevers for 3 days. He had a nonproductive cough that exacerbated the chest pain. A clinical examination revealed distressed and slightly tachypneic patient, with blood pressure of 110/90 mmHg, temperature of $39^{\circ}C$, pulse of 90 beats/min, respiratory rate of 24 breaths/min. A chest examination showed significantly diminished breath sounds in the right lung with dullness to percussion. Laboratory investigation demonstrated leukocytosis and a raised C-reactive protein. The results of arterial blood gas analysis revealed moderate hypoxemia. A radiograph and a CT scan of the chest showed extensive consolidation with multifocal low densities, and pleural effusion in the right lung. A diagnostic thoracentesis revealed straw-colored fluid, which was found to be a neutrophil-predominant exudate. At 7 days after admission, the clinical symptoms had not improved and the temperature was still $39^{\circ}C$ despite the aggressive therapy of community-acquired pneumonia. After comprehensive history taking, we realized then that he accidentally aspirated kerosene while siphoning from fuel tank to put into the boiler 3 days ago. Bronchoscopy with bronchial washings could be successful in establishing the diagnosis of hydrocarbon pneumonitis by demonstration of a high lipid-laden macrophage index. Thereafter, the symptoms and radiographic opacities gradually improved, and he was discharged several days later.

An 82-year-old female non-smoker with a history of hypertension presented with increasing dyspnea, cough and some purulent sputum without fever. Upon admission, the patient was in a distressed condition. Auscultation revealed diminished breath sounds with no rales over the right lung. An examination of the heart revealed a regular rhythm and a systolic murmur radiating from the apex of the heart. There was no pitting edema in the lower extremities. The blood tests showed mild leukocytosis and an increased C-reactive protein level. The $O_2$ saturation was 98 % whilst breathing room air. The electrocardiogram demonstrated sinus tachycardia. The chest radiograph showed a moderate cardiomegaly, right lobe infiltrates, and blunting of the both costophrenic sulcus suggesting a small pleural effusion. Three days after admission, the symptoms became slightly aggravated despite being treated with empirical antibiotics for presumed community-acquired pneumonia. Transthoracic color Doppler echocardiography indicated an ejection fraction of 48 %, mild left ventricular enlargement, and moderate left atrial enlargement resulting in severe mitral regurgitation. The clinical symptoms and right pulmonary edema resolved quickly with intravenous furosemide treatment.

This study was done to verify validity of nursing diagnoses related to difficulty in respiratory function. First, content validity was examined by an expert group considering the etiology and the signs / symptoms of three nursing diagnoses - ineffective airway clearance, ineffective breathing pattern, impaired gas exchange. Second, clinical validity was examined by comparing the frequencies of the etiologies and signs / symptoms of the three nursing diagnoses in clinical case studies with the results of the content validity. This study was a descriptive study. The sample consisted of 23 experts (professors, head nurses and clinical instructors) who had had a variety of experiences using nursing diagnoses in clinical practice, and 102 case reports done by senior student nurses of the college of nursing of Y-university. These reports were part of their clinical practice in the ICU. The instrument used for this study was a checklist for etiologies and signs and symptoms based on the literature, Doenges and Moorhouse (1988), Kim, McFarland, McLane (1991), Lee Won Hee et al. (1987), Kim Cho Ja et at. (1988). The data was collected over four month period from May 1992 to Aug. 1992. Data were analyzed using frequencies done with the SPSS / PC＋ package. The results of this study are summarized as follows : 1. General Characteristics of the Expert Group A bachelor degree was held by 43.5% and a master or doctoral degree by 56.5% of the expert group. The average age of the expert group was 35.3 years. Their average clinical experience was 9.3 years and their average experience in clinical practice was 5.9 years. The general characteristics of the patients showed that there were more women than men, that the age range was from 1 to over 80. Most of their medical diagnoses were diagnoses related to the respiratory. system, circulation or neurologic system, and 50% or more of them had a ventilator with intubation or a tracheostomy. The number of cases for each nursing diagnoses was : · Ineffective airway clearance, 92 cases. · Ineffective breathing pattern, 18 cases. · Impaired gas exchange, 22 cases. 2. The opinion of the expert group as to the classification of the etiology, and signs and symptoms of the three nursing diagnoses was as follows : · In 31.8% of the cases the classification of etiology was clear. · In 22.7%, the classification of signs and symptoms was clear. · In 17.4%, the classification of nursing interventions was clear. 3. In the expert group 80% or mere agreed to ‘dysp-nea’as a common sign and symptom of the three nursing diagnoses. The distinguishing signs and symptoms of (Ineffective airway clearance) were ‘sputum’, ‘cough’, ‘abnormal respiratory sounds : rales’. The distinguishing sings and symptoms of (Ineffective breathing pattern) were ‘tachypnea’, ‘use of accessory muscle of respiration’, ‘orthopnea’ and for (Impaired gas exchange) it was ‘abnormal arterial blood gas’, 4. The distribution of etiology, and signs and symptoms of the three nursing diagnoses was as follows : · There was a high frequency of ‘increased secretion from the bronchus and trachea’ in both the expert group and the case reports as the etiology of ineffective airway clearance. · For the etiologies for ineffective breathing pat-tern, ‘rain’, ‘anxiety’, ‘fear’, ‘obstructions of the tract, ca and bronchus’ had a high ratio in the ex-pert group and ‘decreased expansion of lung’ in the case reports. · For the etiologies for impaired gas exchanges, ‘altered oxygen -carrying capacity of the blood’ and ‘excess accumulation of interstitial fluid in lung’ had a high ratio in the expert group and ‘altered oxygen supply’ in the case reports. · For signs and symptoms for ineffective airway clearance, ‘dyspnea’, ‘altered amount and character of sputum’ were included by 100% of the expert group. ‘Abnormal respiratory. sound(rate, rhonchi)’ were included by a high ratio of the expert group. · For the signs and symptoms for ineffective breathing pattern. ‘dyspnea’, ‘shortness of breath’ were included by 100% of the expert group. In the case reports, ‘dyspnea’ and ‘tachypnea’ were reported as signs and symptoms. · For the sign and symptoms for impaired gas exchange, ‘hypoxia’ and ‘cyanosis’ had a high ratio in the expert group. In the case report, ‘hypercapnia’, ‘hypoxia’ and ‘inability to remove secretions’ were reported as signs and symptoms. In summary, the similarity of the etiologies and signs and symptoms of the three nursing diagnoses related to difficulty in respiratory function makes it difficult to distinguish among them But the clinical validity of three nursing diagnoses was established through this study, and at last one sign and symp-tom was defined for each diagnosis.

Purpose : The risk of severe tuberculous disease such as meningitis or miliary tuberculosis increases as younger is the child at the time of infection. Therefore, the early diagnosis and prompt treatment is mandatory for infants with tuberculosis. This study was undertaken to describe the epidemiology, clinical and radiographic manifestations, and response to therapy in infants with tuberculous disease. Methods : Medical records of 29 infants with tuberculosis diagnosed at the Seoul National University Children's Hospital from July, 1985, to April, 1997, were reviewed, retrospectively. A case of tuberculosis was confirmed if M. tuberculosis was isolated from any body site or if there was histologic proof of tuberculosis. Otherwise, the diagnoses were individualized considering history of contact with contagious adult case, clinical manifestations, chest X-ray findings, result of a Mantoux test reaction with 5 tuberculin unit of PPD, and the response to therapy. Results : The mean age at diagnosis was $7.00{\pm}2.65$ months (range, 3 to 12 months). Twelve cases had isolated pulmonary diseases, and the rest had pulmonary disease and meningitis, 5 cases; pulmonary disease and cervical lymphadenitis, 3; isolated meningitis, 3; and miliary tuberculosis, 6. Source case was identified in 19 cases, 7 of which were detected with retrograde manner. Twenty seven of 29 were symptomatic at their initial visit. The presenting symptoms were mainly respiratory or neurologic, and respiratory difficulty was accompanied in 7 cases. Physical examination revealed wheezing in 7 cases and decreased breath sounds in 9. Hepatomegaly or hepatosplenomegaly were frequent. Chest radiographs showed lung parenchymal disease with hilar lymphadenopathy in 18 cases, and focal or generalized emphysematous change in 7 cases. Conclusion : Most of the infants with tuberculosis are symptomatic at diagnosis, and many of infants with intrathoracic tuberculosis presented with symptoms of bronchial obstruction. When tuberculosis is suspected in an infant, the adult source case should be vigorously investigated to aid in diagnosis and for the prevention of further transmission of tuberculous disease. Almost half of infant tuberculosis are preventable if prophylaxis were given when adult cases were diagnosed.
