Background: The surgical repair of an isolated coarctation of the aorta, without complex cardiac anomalies, has improved, with very good results. However, despite the success of surgical repair, many long-term complications, such as hypertension, re-coarctation and an aortic aneurysm, still exist. Material and Method: Between 1991 and 2006, 50 patients diagnosed with an isolated coarctation of the aorta were reviewed retrospectively. The incidence of re-coarctation and hypertension were compared with respect to age and surgical methods. Result: There were no early & late mortality, or post operative aortic aneurysms. Hypertension developed in 11 patients (22%). A greater number of patients in the child/adult group had hypertension (52.4%) than in the neonate/infant group (0%). With respect to the surgical methods, the patients in the graft interposition group suffered more hypertension (88.9%) than those in the EEEA (extended end to end anastomosis) group (5.3%). Post operative re-coarctation developed in 2 out of the 29 patients (6.9%) in the neonate/infant group and 2 out of the 21 patients (9.5%) in the child/adult group, but without any statistical difference. There were no statistical differences between the operative type-related groups. Conclusion: Even though the surgical outcomes have greatly improved, an isolated coarctation of the aorta still has many long-term problems, such as hypertension and re-coarctation. An isolated coarctation is accepted as a systemic vascular dysfunction, and often progresses to other cardiovascular diseases. Therefore, patients with a coarctation of the aorta have to be carefully followed-up, and aggressive management must be given when required.

This study focused on the brand attitude of consumers toward social innovation companies so that they could have differentiated competitive advantage and secure competitive advantage with ordinary companies. To this end, the difference in consumer brand attitudes between products of social innovation entities and products of general enterprises was compared through blind testing. The blind test results of this study showed that there was no statistically significant difference in product properties or brand attitudes, but after the information of the after-sales product was disclosed, the information included that the soap product used as a laboratory was natural handmade soap, indicating that post-brand attitudes improved in both social innovation and general enterprise products. And after explaining the social values pursued by social innovators, the increased interest in social innovation firms compared to ordinary enterprises resulted in a statistically significant increase in brand attitudes toward social innovation enterprise products. Clear and unexaggerated information displays on product packaging can be a tool to improve brand attitudes. In addition, in order to raise consumer awareness of social innovation enterprise products, there will be a need to enhance education and promotion policies for social innovation companies at the government level, and developing self-help measures for social innovation companies to promote themselves by presenting the contents of their social values as advertising copy on their product packaging may also be another breakthrough for improving brand attitudes and increasing sales.

Purpose: Normal education operation was difficult in the national disaster situation of Coronavirus Infection-19. Non-face-to-face education can be an alternative to face to face education, but it is not easy to provide the same level of education. In this study, the professor of disaster management field will identify problems that can occur in the overall operation and progress of non-face-to-face education and seek ways to improve non-face-to-face education. Method: Non-face-to-face real-time education was largely categorized into pre-class, in-class, post-class, and evaluation, and case studies were conducted through the professor's case studies. Result&Conclusion: The results of the survey are as follows: First, pre-class, it was worth considering providing a non-face-to-face educational place for professors, and the need for prior education on non-face-to-face educational equipment and systems was required. In addition, it seems necessary to make sure that education is operated smoothly by giving enough notice on classes and to make efforts to develop non-face-to-face education programs for practical class. Second, communication between professor and learner, and among learners can be an important factor in non-face-to-face mid classes. To this end, it is necessary to actively utilize debate-type classes to lead learners to participate in education and enhance the educational effect through constant interaction. Third, non-face-to-face post classes, policies on the protection of privacy due to video records should be prepared to protect the privacy of professors in advance, and copyright infringement on educational materials should also be considered. In addition, it is necessary to devise various methods for fair and objective evaluation. According to the results of the interview, in the contents, which are components of non-face-to-face education, non-face-to-face education requires detailed plans on the number of students, contents, and curriculum suitable for non-face-to-face education from the design of the education. In the system, it is necessary to give the professor enough time to fully learn and familiarize with the function of the program through pre-education on the program before the professor gives non-face-to-face classes, and to operate the helpdesk, which can thoroughly check the pre-examination before non-face-to-face education and quickly resolve the problem in case of a problem.

This study is a report of an intensive ESP(English for Specific Purposes) program conducted for the College of Economic students in Korean University. This is planned for the students to enhance their English achievement in comprehending the subject contents which they would learn in the near future. In order to determine whether the course helped the students enhance their English achievement or not, a pre and post test were taken, one at the beginning of the semester and the other at the end of semester. The result of the test shows that this program benefits relevant students, especially lower level students. In accordance with a general accepted view, the English for Specific Purposes(ESP) program is generally targeted for students who expect to learn the basic knowledge of English through mediated courses. Since students already have specific purpose of studying for their major courses, their motivation and interest in the course are higher than the students who don't have any specific purpose. Therefore, this study shows that the students who took English for Specific Purposes(ESP) had higher motivation and interest to study English related to their major courses as the test results were higher than before they had taken the English for Specific Purposes (ESP) program.

This study compared the survival rates, growth, and fatty acid content of larval Pacific cod Gadus macrocephalus fed with rotifers raised on different enrichment diets. We used four commercial rotifer enrichment products (one domestic, ER1, and three imported, ER2, ER3 and ER4). Twelve 200-L tanks were used, with three replicates per treatment. Larvae were fed rotifers 3 times daily at a rate of 5 rotifers/ml/feeding from 7 to 21 days post-hatch. At the end of the feeding trial, the survival rate and total length of larvae fed ER3 were greater than those of larvae fed ER1, ER2, or ER4. ER3 had the highest proportions of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and polyunsaturated acid (PUFA). Partially reflecting this composition, larvae fed ER3 had the highest proportions of DHA and PUFA. These results show a positive effect of rotifer DHA and PUFA proportions on the survival and growth rates of Pacific cod larvae.

Orthognathic surgery for the correction of dentofacial deformities is a common elective procedure. That has proven over the years to be a safe operation with minimal long-term morbidity. But, there are many surgical complication including mal-union of the bone, TMJ problem, excessive bleeding, and permanent damage of inferior alveolar nerve. Among them excessive bleeding which focus is not clear is one of the serious complication because that is fatal and so a transfusion is performing for the prevention and management of that. Until the end of the 1980's, homologous blood transfusions were routinely necessary because of the large amounts of blood lost during surgery. Recently several blood-saving measures can be undertaken for orthognathic surgery patients before, during, and after the operation. We made a comparative study of an amount of blood loss, hematologic change and transfusion requirements based on a series of 40 consecutive patients undergoing single-jaw and double-jaw surgery. The purpose of this investigation was to make a comparative analysis of an amount of blood loss, post-operative hematologic change and duration of the procedure under induced hypotensive anesthesia in healthy orthognathic patients.

Recently, due to the temporary closure and isolation of facilities for developmental disabilities due to the prolonged COVID-19, the pain suffered by consumers is getting worse, and there is no clear solution due to the lack of information on inpatient services. Therefore, there is a need for a service system that can prevent institutional and psychological problems for consumers. The purpose of this study is to provide systematic inpatient treatment guides, post-discharge management, and correct education for children with developmental disabilities and their guardians. After deriving the needs and improvement factors of consumers through domestic service case analysis, we conducted co-creation with end-users using the double diamond methodology. A possible service concept was derived. Accordingly, a collaborative sharing app service was proposed, and the usefulness of the service was confirmed through the usability evaluation and verification of various stakeholders. It is expected that the results of this study will be utilized in the development of an assistance system for the developmental disability ward based on user experience.
