An 8-year-old castrated male domestic shorthair cat (Case 1) and 3-year-old castrated male Siamese cat (Case 2) was presented with acute paresis of the hindlimbs, constant open-mouth breathing, and hemoptysis. Heart murmur (Case 1) and gallop sound (Case 2) was ausculated on the left heart base. Radiographs revealed alveolar infiltration of the caudodorsal lung lobes with aerophagea in Case 1 and prominent cardiomegaly in Case 2. Marked concentric hypertrophy of the ventricular septum and free wall, and left atrial enlargement was detected through echocardiography in both cats. Based on the examinations including echocardiography, those cats were diagnosed as hypertropic cardiomyopathy. Abdominal ultrasound revealed echogenic material in the aortic trifurcation region, aortic thromboembolism (ATE). Although prognosis of those animals was guarded, interventional therapeutic approach through direct endovascular thrombolytic therapy was attempted. ATE was visualized through angiography; however dissolving the embolus using interventional thrombolytic approach was not successful due to the extensive thrombus.

전지 파행을 호소하여 의뢰된 약 2개월령의 진도개 암캐에서 비대성골이영양증이 진단되었다. 내원 2일 전부터 파행과 침울 증상을 보인 이 개의 이학적인 검사 결과 grade II/IV 정도의 좌측 전지파행이 관찰되었으며, 좌측과 우측의 앞발목관절의 미약한 종대가 인정되었다. 좌측발목관절을 촉진한 결과 요골과 척골의 골단부위를 촉진할 때 심한 통증을 호소하였으며, 우측 앞발목관절의 촉진에서도 미약한 통증이 인정되었다. 좌측과 우측 앞발목관절의 x-ray 검사에서 양측 전지 원위 요골 및 척골의 성장절 바로 위쪽 골간단에 성장절과 나란히 존재하는 불규칙한 방사선투과성의 선이 관찰되었고, 이 부위의 바로 아래쪽과 위쪽에는 방사선투과성이 감소되어 있었다. 이상의 결과 비대성골이영양증으로 진단되었다. ketoprofen과 amoxicillin을 투여하고, 운동을 철저히 제한한 결과 이 개의 증상은 빠르게 호전되었으며, 치료 2일 후 파행증상이 완전히 소실되었고, 증상이 재발되지 않았다. 이 보고에서는 진도개에 발생한 비대성골이영양증을 처음으로 소개하면서 이 질환으로 원인, 진단 및 치료에 대해 문헌적으로 고찰되었다.

A case is described in a girl who presented with recurrent life-threatening hemoptysis at the age of 18 months, and had been diagnosed as atrial septal defect with severe cardiomegaly which was presumed to result in pulmonary vein stenosis at the age of 6 months. Closure of atrial septal defect was associated with decreased heart size and improved pulmonary venous flow. However, recurrent life-threatening hemoptysis occurred during follow-up, Computed tomography scan demonstrated left pulmonary vein stenosis and extrinsic compression of the left bronchus by multiple soft tissue density-masses. Exploratory thoracotomy revealed single stenotic left pulmonary vein, and flat left main bronchus compressed by multiple hypertrophied lymph nodes, Unexpected endotrachial tube bleeding during left hilar dissection mandated to proceed to left pneumonectomy, The patient's postoperative course was uneventful. Follow-up chest roentgenography revealed acceptable left hydrothorax without mediastinal shifting, Nevertheless, a long-term follow-up is necessary.

심폐바이패스를 사용하지 않고 심장박동 상태에서 시행하는 관상동맥 우회수술은 심 비대와 좌심실 기능저하가 동반된 협증심 환자에서는 심장 뒤쪽에 위치한 관상동맥에 대한 접근이 어렵고 수술 중 혈역학적으로 불안정하여 시행하기에 어려운 경우가 많다. 우심실 보조장치 하의 심장박동 상태에서 시행하는 관상동맥 우회수술은 대동맥의 삽관을 피하고, 심폐바이패스의 합병증을 줄일 수 있으며, 심장 뒤쪽에 위치한 혈관의 문합시에도 안정된 혈역학적 상태를 유지 할 수 있어 고위험군 환자에게 도움을 줄 수 있다. 좌심실 기능저하와 심 비대가 동반된 환자에서 우심실 보조장치 하의 심장박동 상태에서 시행한 관상동맥 우회수술을 2례 시행하여 좋은 결과를 얻어 보고하고자 한다.

Although left Left ventricular hypertrophy (LVH) is not only an adaptive response of the heart to increased cardiac workload in hypertension, it surelybut also is the most potent risk factor of overt cardiovascular complications such as coronary heart disease, heart failure, arrhythmia and stroke in the hypertensive population. Also it has become generally accepted that subclinical cardiovascular disease begins in childhood and LVH is the most readily assessed marker for that. As LVH can be seen in children and adolescents with even mild blood pressure elevation with the reported prevalence of 10 to 47%, aggressive antihypertensive treatment is critical in preventing the development of hypertensive heart disease in that those cases.

A 4-years-old, intact male Golden retriever dog was presented with abdominal distension and dyspnea. Physical examination revealed arrhythmia and cardiac murmur. Generalized cardiomegaly, pleural effusion and ascites were shown on thoracic and abdominal radiographs. Two-dimensional echocardiography revealed abnormal mitral and tricuspid valve motion, mitral and tricuspid regurgitation, left ventricular eccentric hypertrophy and left atrial dilation. Color-flow Doppler imaging revealed turbulent flow extending into the left ventricle during diastole from the mitral valve orifice, and into the left atrium during systole. Spectral Doppler recordings revealed highly increased early diastolic mitral valve inflow and prolonged pressure half-time of mitral inflow. Based on the echocardiographic examination, the diagnosis was made as the mitral valve dysplasia concurrent with mitral valve stenosis and tricuspid valve dysplasia.

The argument-structure distributions of predicates in the speech of two roca-type aphasic patients and one Conduction-type patient are compared with both matched controls and each other on the basis of narrative production data. Whereas English-speaking agrammatics have been reported to have difficulties producing noncopular unaccusative predicates (Kegl 1995) Korean-speaking agrammatics are found not to have particular difficulties with unaccusative predicates. On the assumption that agrammatics lack specific syntactic knowledge for the processing of displaced arguments from their lexically specified positions. it is proposed that unaccusatives in Korean do not involve the displacement of arguments for Case-theoretic reasons or involve a vacuous movement. if any.

Mass electrocardiographic (ECG) examination was performed on 13,801 children (male 7,526 and female 6,275) of elementary and middle school in Taegu from May 1. 1986. to April 30. 1987. We read their ECG according to the "Pediatric Electrocardiography." The results were as following; The Incidence of ECG abnormality was 1.05%(male 1.3% and female 0.75%). Fifty eight children (0.42%) had atrial and ventricular hypertrophy; two right atrial hypertrophy, five left atrial hypertrophy, thirty five fight ventricular hypertrophy and sixteen left ventricular hypertrophy respectively. Ectopic beats occurred in 25 children (0.18%) ; They were atrial in 12 children, ventricular in 8 children and junctional in 5 children. There were 62 children (0.45%) of conduction disturbance ; They were first degree atrioventricular (A-V) block in 21 children, type I second degree A-V block in 1 child, A-V dissociation in 1 child, right bundle branch block in 36 children, left bundle branch block in 1 child and WPW syndrome in 2 children. Nonspecific ST, T changes and sinus tachycardia were found in 3 and one children respectively.

The development of information and communication technology and COVID-19 have caused an unusual change in the hotel industry, and the demand for the contactless services such as service robots from hotel customers has surged. Therefore, this study investigates the perception of hotel customers on contactless services by applying a mixed-method analysis. Specifically, this study identified the causal correlations between variables through the structural equation model, and further applied the fuzzy set qualitative comparison analysis to derive patterns of variables that form the intention to use the non-face-to-face services. As a result of the analysis, it was shown that service experience co-creation, palyfulness, personalization, and trust had a significant effect on intention to use through the contactless service use desire. On the other hand, in the results of fuzzy-set qualitative comparison analysis, playfulness was derived as a core factor in all patterns. Based on these analysis results, this study provides academic basis for in-depth understanding of hotel customers' perception of contactless service and specific guidelines for hotel managers on the contactless service strategies in the era of COVID-19 pandemic.

Patients with severe Ebstein's anomaly showing in the neonatal period, represent progressive cardiac enlargement with pulmonary hypoplasia and functional pulmonary atresia with patent ductus alteriosus-dependent pulmonary circulation. Biventricular repair in these patients had been mostly unsuccessful except for Starnes' procedure that converts the anatomy to single ventricle physiology for Fontan procedure. A 4-days old male was admitted with the diagnosis of severe Ebstein's anomaly with anatomic pulmonary atresia and severe cardiac enlargement. He successfully underwent biventricular repair with vertical plication method of atrialized right ventricle, tricupid annuloplasty, transannular right ventricular outflow tract reconstrulltion, atrial septal defect patch closure with fenestration, and right atrial reduction angioplasty Postoperatively, cardiothoracic ratio was significantly reduced and mild tricuspid regurgitation was remnant in echocardiography. The patient is currently 10 months old and is fully active without restrictions.
