During a fire-year period from March 1979 to February 1984, 559 patients underwent surgical treatment for rheumatic mitral valve disease at Seoul National University Hospital. Left atrial thrombus was found at surgery in 74 of these patients, an incidence of 13.2%. This report outlines the surgical experience with these seventy-four patients. They were 32 men and 42 women, and their age ranged between 23 and 57 with mean of 42 years old. All except one had the findings of atrial fibrillation on the preoperative electrocardiogram. Ten [13.5%] had experienced embolic events before surgery. A history of one or more episodes of cardiac failure requiring digitalis and diuretics was noted in all patients Nineteen were associated with the aortic and/or tricuspid valve disease and closed mitral commissurotomy had been performed previously in four patients. The average cardiac index was 2.68L/min/M2 [1.59 to 3.47 L/min/M2] The mean systolic pulmonary artery pressure was 57mmHg [26 to 120 mmHg]and pulmonary capillary wedge pressure 21.5 mmHg [12 to 40 mmHg]. There were no significant hemodynamic findings to suggest the presence of the left atrial thrombus. Operative mortality was acceptable with two early deaths [2.7%]. The follow-up of the hospital survivors has shown excellent functional status.

The goal of this study is to examine the relationship between efficacy belief and role performance of childcare teachers, and also to utilize the results as the basic data for teacher education. The subjects were 205 teachers at 48 childcare centers located in Jeonlabuk-do area. The instruments employed included efficacy belief, teachers' role performance, experiences, and age. The data were analyzed by t-test, Pearson correlation, and Regression Analysis. The results of this study are as follows: First, the role of child carer was the vest performance through childcare teachers' role. Second, the role of instructor, counselor, researcher, and others was significantly different among the types of childcare institution. Third, the social position of ability and personal teaching efficacy belief were correlated positively with teachers' experience. The activeness, the social position of ability, general teaching efficacy belief, personal teaching efficacy belief, and the role of child carer, instructor, counselor, researcher, and others were correlated positively with teachers' age. Fourth, the role of child carer, instructor, counselor, researcher, and others was correlated positively with the activeness and the social position of ability, whereas it was correlated negatively with failure anxiety. Lastly, the activeness was the most powerful variable influencing teachers' role performance.

Due to its nature, business foundation accompanies high levels of risk taking and responsibility. For this reason, entrepreneurs come to experience various negative emotions in the process of business foundation such as anxiety about risks, fear of failure, and pressure of success. However, entrepreneurs' negative emotions reduce individual inclinations for business foundation. Thus, it is necessary to research individual psychological characteristics that could reduce and attenuate entrepreneurs' negative emotions. To this end, this study examined the effects of Self-forgiveness, and Narcissism, psychological motivation variables, and Positive psychological capital and Career ambition, goal motivation variables, on entrepreneurial intentions. In order to verify research hypotheses, 326 questionnaires collected from prep-entrepreneurs were used for the empirical analysis. Looking at the analysis results, Self-forgiveness, Narcissism, Positive psychological capital and Career ambition had significant effects on entrepreneurial intentions. This study has a meaning in that it confirmed the influential relationship between the psychological characteristics reducing entrepreneurs' negative emotions and entrepreneurial intentions. In addition, this study suggested its implications, limitations, and future research directions based on the study results.

The urban modernity that became an irresistible model for elites in Asia in the decades before and after 1900 was far from being gender-neutral. It represented an exceptional peak of patriarchy in its exclusion of respectable middle class women from the work force, from ownership and control of property and from politics. Marriage was indissoluble and the wife's role in the male-headed nuclear family was to care for and educate the abundant children she produced. Puritan religious values underlined the perils for women of falling outside this pattern of dependence on the male. Though upheld as modern and civilized, this ideal was in particularly striking contrast with the pre-colonial Southeast Asian pattern of economic autonomy and balance between women and men, and the relative ease of female-initiated divorce. Although attractive to many western-educated Southeast Asian men, including religious reformers determined to 'save' and domesticate women, urban respectability of this type was a poor fit for women accustomed to dominant roles in commerce and marketing, and at least equal ones in production. Southeast Asian relative failure in the high colonial era to adapt to the modern market economy may also have a gendered explanation. We should not be surprised that patriarchy and puritanism became more important in Southeast Asia as it urbanized in the late 20th Century, since this was echoing the European experience a century earlier. The question remains how far Southeast Asia could retain its relatively balanced gender pattern in face of its eventual rapid urbanization and commercial development.

With various success stories of crowdfunding, government's establishment of crowdfunding act, and expected rapid growth of crowdfunding market, the potential ripple effect of crowdfunding on our society is anticipated to be enormous. This study investigates the influential factors and their impacts on the likelihood of project success in donation-based crowdfunding through the DonorsChoose case. The authors analyze the characteristics of project creator, characteristics of project, and behaviors of project participants in relation to the success or failure of the corresponding project. Consequently, the authors found that participants of donation-based crowdfunding exhibit altruistic behaviors and obtained the following specific results: First, donation participation and social capital of the project creator, and marginal help utility of receivers positively affect the success of project. Second, experience of past project creation of the project creator negatively affects the success of project. Third, past donations of the project creator to others' projects, when not appropriately signaled like on the DonorsChoose platform, may not exert a positive influence on the success of project and the reciprocity principle may not work.

Though customer delight is becoming one of the most important marketing key words, research in a retail setting is limited. With the dramatic growth of online retail shopping, this study explored customer delight experiences in online shopping malls by identifying the delight elements and analyzing the elements by online purchase steps. A total of 124 delight experiences collected from an unstructured questionnaire were content-analyzed. Delight elements in online shopping were categorized into service, product, price, delivery, package, and shopping mall operation in that order. Service related elements including free gifts and letters, recovery efforts for service failure, kind employees, and easy return were most frequently observed. Delights were experienced at the product receiving point, the prior-to-purchase point, the order-to-delivery point, and the post-purchase point in that order. The results revealed that customer delights in online shopping were experienced in various purchase steps by various marketing elements. Based on the results the study provided research propositions exploring the effects of expectation vs surprise, monetary vs non-monetary/emotional benefits/rewards, and core marketing elements vs augmented services on delight experiences.

Clinical experience of 21 patients with infective endocarditis was reviewed. Endocarditis involved the left-sided valve in 16 cases, the right-sided valve in 2, and PDA in the remaining 3 patients. Valve abnormalities included leaflet perforation in 9 patients, chordal rupture in 2,; annular abscess in 6; and aorticoleft atnal perforation in 2. Sixteen patients underwent valve replacement[aortic valve replacement in 7 patients, mitral replacement in 4 and double valve replacement in 5], two had VSD closure with pulmonary valve excision, three had ductus arteriousus closure. The patients were classified into two groups. I ] Healed endocarditis group: including the patients who had completed a planned cou-rseof antibiotic therapy[N=10], II ] Active endocarditis group: patients in which operations were performed prior to completetion of antibiotic treatment course[N=11]. The indications for operation included congestive heart failure, embolism, and persistent sepsis. Organisms were predominantly streptococcus[N=5] and staphylococcus [N=4] followed by candida, moraxella, and E-coli. By NYHA functional classification, all patients were in Class III or IV preoperatively. There was only one operative mortality in patient from group II. All patients substantially, improved postoperatively with NYHA classification in class I or II. This study shows that early surgical intervention in patients with active endocarditis has desirable outcome.

Clinical and pathologic data were reviewed in 20 patients who had have surgery for isolated aortic valvular heart disease between April 1978 and April, 1987. Hospital mortality was 10%, with no additional late mortality during a mean follow-up period of 24.1 months. Prosthetic valve failure developed in 3 patients and two had reoperation. Niety four percent of the survivors who were in NYHA Funtional class III or IV before operation are now in class I or II. Ninety percent of all patients are still alive at a maximum follow up of 9 years. The clinical histories, gross and histologic examination of valves estabilished the causes for isolated aortic valve disease: 3 rheumatic, 2 congenital bicuspid, 2 hypertention, 2 aortitis and each one case of floppy valve, medial cystic necrosis of aorta, bacterial endocarditis. But etiology was unknown in 8 cases. Sixteen patietns had myxoid degeneration, defined as significant disruption of the valve fibrosa and its replacement by acid mucosaccharides and cystic changes. Myxoid degeneration was also the primary pathologic abnormality in the patients with 2 hypertention, 2 rheumatic, 1 aortitis, 1 bacterial endocarditis, 1 floppy valve, 1 congenital bicuspid. The patients with myxoid degeneration of uncertain origin were 8. Histologic finding of all of them revealed nonspecific patients with myxoid degeneration of uncertain orgin were 8. Histologic finding of all of them revealed nonspecific chronic valvulitis with myxoid degeneration. This finding may indicate that the etiology w uld be infectious.

Records of 71 consecutive patients who had received multiple valve replacement were reviewed[34male,37female,mean age 40.5$\pm$11.2 <14-63> . The early death rate was 2.8%[2/71 . A completed follow-up rate of 95.7% was accomplished in these 69 patients who left hospital[mean 42.5 $\pm$29.5 patients-years . Five of these patients died. The late death rate was 7.2%. Four patients experienced anticoagulant-related hemorrhage[all were minor . One patient had a thromboembolic episode[permanent ,and 2 had late prosthetic valve endocarditis. There was no clinical evidence of hemolysis and structural failure of valves used. Of those patients who survived,NYHA functional class improved significantly[from 87.2% class III & IV before to 95.8% class I & II after . Linearized rates for thromboembolism and anticoagulant-related hemorrhage,and for prosthetic valve endocarditis were 0.67%/100 patient-years,2.95%/100 patient-years,1.34%/100 patient-years, respectively. The actuarial estimates of incidence free of all complications and valve-related deaths were 92.2%/patient-years.Despites the advanced heart disease involving two or more native valves, the patients who had multiple valve replacement had very good results, over a 9-year period.

Although Korean university students' primary concern is academic success in their higher degrees in the UK, they highly desire to develop English communicative competence through a number of opportunities to speak with natives speakers. The paper aims at examining to what extent they are able to be socialised into a new environment while they are studying at UK universities. The in-depth, longitudinal interviews with the targeted group of six Korean masters' students at the University of York was undertaken to observe the pace of their progress in developing social skills. Reluctance and hesitance to contact and interact with their supervisors and other academic staff persisted for most of them to the final term caused by cultural reasons such as face and hierarchy rather than language problems. Despite the six participants' variation in their patterns of social interaction, they struggled with pressures towards monoculture-biased interaction with Korean people, which was quite extreme for the five participants. This passivity can be explained by several reasons such as the students' lack of communicative competence and other situational factors on one-year course. It is important to note that students' failure to develop network with native speakers is strongly associated with experience of cultural withdrawal and frustration with developing communicative competence in English.
