During 22-year period ending in June 1988, operation was performed on 22 patients with primary heart tumor at Yonsei University College of Medicine. Mean age was 38.8*3.03[mean \ulcornerEM] ranging from 14 to 63 years old. Twenty cases were myxomas. Others were fibromyxoma and rhabdomyosarcoma. All patients complained of dyspnea on exertion. Nine cases had palpitation. Other constitutional symptoms were weight loss [7 cases], headache [4 cases], generalized edema [3 cases] and cough [3 cases]. Five cases had neurological symptoms and signs preoperatively. Preoperative NYHA Class was poor [Class II; 8 cases, III; 9 cases and IV; 5 cases]. The most common site of tumor origin was fossa ovalis limbus [16 cases; 72.8%]. Because of severe mitral regurgitation and of recurrent myxoma, 2 cases were reoperated for mitral valve replacement. Postoperative complications were postoperative mitral regurgitation [5 cases; 22.8%] and arrhythmia [4 cases; 18.2%], one of which was supra-His bundle block. All patient survived operation. Follow-up of 15 patients [mean 28.95*8.3 months] was good as functional class 1[8 cases] or II [7 cases]. More effective adjuvant therapy will be necessary to improve long-term prognosis for malignant primary heart tumor.

A total of 54 patients with mitral stenosis were treated in the Dept.of Thoracic and Cardiovascular Surgery. Chonnam National University Hospital, during the 17-year period from Jan., 1962 to June, 1978. There were 35 men and 19 women with sex ratio of 1.8 : 1. The age of the patient varied widely from 15 years of the youngest to 48 years of the oldest. Preoper ative functional levels according to N.Y.H.A. classification were class II in 19% of cases, class III in 69%, and class IV in 12%. 53 patients were underwent closed operations; 43 cases had closed digital mitral commissurotomy and 10 cases had closed dilator mitral commissurotomy, Hospital mortality was I case (1. 9%). Results of operations were good and excellent in 48cases(91%).Most of the survivors left hospital in a good and improved condition.

During one year period from Sep. 1986 to Sep. 1987, we have experienced 6 cases of infective endocarditis requiring surgical interventions. All 6 patients had class IV or V cardiac disability at the time of surgery. The indication for surgery was rapidly progressive congestive heart failure in all cases. Four patients underwent aortic valve replacement including one double valve replacement. Two other patients required other surgical procedures, removal of large left atrial vegetation mass in one patient and excision of destroyed pulmonary valve and aortic vegetation in the other patient. Two patients died; one of mitral annulus rupture after release of aortic clamp and the other of mediastinal bleeding 3 months after replacement of aortic valve. Three out of 4 survivors are in NYHA Class I and the remaining patient is in Class II. We emphasize that early operative intervention is life-saving in patients with persistent or progressive congestive heart failure, irrespective of the activity of the infective process or the duration of antibiotic therapy.

Purpose: This study was conducted to investigate the effect of flipped-learning method on dental hygiene practice satisfaction. Methods: The study was a patient-group crossover design involving 53 third-year students at D's Department of Dental Hygiene. The study tools used self-questionnair and the analysis program used SPSS Ver 25.0. Results: Class satisfaction increased to 3.85 in the first semester and 4.23 in the second semester (p <0.05). Satisfaction with the flip learning method was 4.26, and most answered yes. In addition, it showed a positive effect on class satisfaction (p <0.01). As a result, it can be seen that the flip-learning learning method has a positive effect on the learners' learning motivation, academic achievement, and class satisfaction. Conclusions: it is considered that the flip learning method for hands-on classes should be expanded for the purpose of fostering job competency and high quality clinical practice experts.

The author surveyed traumatized anterior teeth of 12~17 year old 9453(male 4740, female 4713) school students. The results were as follows: 1. The prevalence of traumatized anterior teeth was $10.3{\pm}0.6%$. 2. The prevalence of traumatized anterior teeth of male was $12.2{\pm}0.9%$, and that of female was $8.4{\pm}0.8%$. The prevalence of male was higher than that of female. 3. The distribution of traumatized teeth by severity was as follows: Class I-65.3%, Class II-20.7%, Class III-8.2%, Missing teeth-5.4%, Others-0.4%. 4. Maxillary central incisors had the highest trauma frequence. 5. Single fractures were found to occur more commonly than multiple fractures. 6. The percentage of treated person was 5.1%. 7. 72.3% of the sample was not affected by the traumatized anterior teeth, and 27.7% of the sample thought the traumatized anterior teeth ugly.

This paper presented a course plan based on the ideas I gained from conducting a lecture on Chinese language for students in the second semester of the Chinese language department at a four-year university. In the paper, we sought to deviate from the traditional grammar-translation teaching style and find ways for students to enjoy learning without difficulty in all areas by using the 'total language approach' such as writing, speaking, listening and reading through reading skills. Therefore, we discussed the educational significance and expression of the 'Chinese Languages' class, and introduced the class stages and methods of progress. In other words, they suggested introduction of text plots, explanation of vocabulary and grammar, presentation of original text, questions about text, arrangement of words, ordering sentences to fit the plot, and understanding the plot while looking at the picture.

본 연구는 간호대학생의 과제가치가 수업참여도에 영향을 미치는 과정에서 학업적 자기효능감의 매개효과를 파악하기 위해 시도되었다. 연구대상자는 G시에 소재한 K대학의 간호학과 2학년 재학생 161명으로, 자료수집 기간은 2020년 10월 5일~10월 14일이었다. 과제가치와 수업참여도 간의 관계에서 학업적 자기효능감의 매개효과는 단순 및 다중회귀분석을 활용한 Baron과 Kenny의 3단계 매개효과 검증절차를 이용하여 분석하였고, 매개효과에 대한 통계적 유의성은 Sobel test로 검증하였다. 본 연구결과 과제가치와 학업적 자기효능감은 수업참여도에 영향을 미치는 주요 요인이었으며, 과제가치와 수업참여도 간의 관계에서 학업적 자기효능감은 유의한 부분매개 변인인 것으로 나타났다. 이들 요인은 수업참여도를 55% 설명하였다. 학습자의 수업참여도를 높이기 위해서는 과제가치와 학업적 자기효능감을 향상시킬 수 있는 통합적 접근방법이 필요하다.

본 연구의 목적은 잠재프로파일분석(Latent Profile Analysis)을 적용하여 다문화청소년 어머니의 정신건강의 잠재유형을 분류하고 예측변인의 영향력을 분석한 후 잠재유형의 차이가 부모효능감에 어떠한 영향을 미치는가를 규명하기 위함이다. 이를 위해 다문화청소년 패널조사(MAPS) 9차년도(2019년) 패널데이터를 활용하였다. 분석결과, 첫째, 다문화청소년 어머니의 정신건강 유형은 '정신건강 중간 위험형'(class3) > '자아존중감 상위형'(class1) > '정신건강 고 위험형'(class4) > '문화적응과 일상생활 스트레스 상위형'(class2) 순으로 분석되었다. 둘째, '자아존중감 상위형'(class1) 집단과 비교해 다문화청소년 어머니의 가정경제 수준이 낮을수록, 다문화청소년 아버지(남편)의 학력이 중학교졸업 이하일수록, 한국어 수준이 낮을수록, 자녀와의 의사소통 정도가 낮을수록 '정신건강 중간 위험형'(class3) 집단에 속할 승산(Odds)은 높아지는 것으로 분석되었다. 셋째, '정신건강 중간 위험형'(class3) 집단과 '정신건강 고 위험형'(class4) 집단과 비교해 '자아존중감 상위형'(class1) 집단이 부모효능감에 유의미한 정(+)적인 영향을 미치는 것으로 확인되었다.

A total of and consecutive 291 patients underwent isolated mitral valve replacement using the Ionescu-Shiley bovine pericardial xenograft valve during the 5-year period between October 1978 and June 1983. Thirty-two patients were the children under 15 years of age. There were 15 deaths within 30 days after surgery [operative mortality, 5.2%]. All early survivors except 6 children were placed on the long-term oral anticoagulation longer than postoperative 3 months. A total follow-up period extended for 398.2 patient-years, and 12 patients died [late mortality, 4.1%, or 3.0%/patient- year]. Ten patients experienced the thromboembolic complication [2.51%/patient-year], occurring in 8 patients within the first 3 postoperative months, and 4 died. Three patients had the late prosthetic valve endocarditis [0.75%/patient-year] and 2 died. The incidence of overall valve failure according to the criteria was 3.01%/patient-year, or 12 patients, and 2 had replacement of the failed bioprostheses [primary tissue failure, 0.5%/patient-year]. The long-term survival rate was 87.8%\ulcorner2.6% at 5 years postoperatively, and 84% of the late survivors were in NYHA Class I at the end of the follow- up. The probability remaining free from thromboembolism and overall valve failure was 89.8%\ulcorner6.3% and 81.2%\ulcorner.8% at 5 years respectively. These clinical results confirm the safety of mitral valve replacement. The only remaining clinical problem is the structural and functional durability of the bovine pericardial xenograft valve, and its use in young patients may be stopped in preference to the mechanical prosthetic valves.
