A 3-year-old castrated male Korean domestic short-haired cat (weighing 5.2 kg) was referred to the Kangwon National University Veterinary Teaching Hospital, with primary complaints of ascites, pleural effusion and respiratory distress. Diagnostic studies revealed marked chylous and hemorrhagic pleural effusion, cardiomegaly, restrictive filling pattern of transmitral flow and mitral annular tissue Doppler profiles and minimally thickened left ventricular free wall. Based on the echocardiographic findings, the case was tentatively diagnosed as restrictive cardiomyopathy. The case was treated with removal of pleural effusion and medical therapy including furosemide, enalapril, sildenafil, clopidogrel. This is the first case report of restrictive cardiomyopathy in Korea.

Background: Patients with advanced asthma and chronic obstructive pulmonary disease (COPD) have postural deviations such as thoracic hyperkyphosis, forward shoulder posture (FSP) due to an increase in head and cervical protraction, reduced shoulder range of motion and a corresponding increase in scapula elevation and upward rotation. Unlike congenital vertebral kyphosis that are permanent and rigid deformities with bony and other structural deformations which cause respiratory impairment, these deformities in these patients may be more flexible. Since the thoracic hyperkyphosis has been implicated as having adverse health consequences it is necessary to evaluated the relationship between thoracic kyphosis and cardiopulmonary functions of patients with COPD and asthma. Methods: It was a cross-sectional analytical study. Eighty-four eligible patients with COPD and asthma were recruited from the Respiratory Unit, Department of Medicine, Lagos University Teaching Hospital (LUTH), and basic anthropometric parameters, pulmonary parameters, cardiovascular parameters, thoracic kyphosis (Cobb) angle and presence of respiratory symptoms of participants were assessed. Data was analyzed using SPSS version 20. Results: There was no significant correlation between the thoracic kyphosis and selected pulmonary parameters (Forced Expiratory Volume in one second (FEV1, p=0.36), Forced Vital Capacity (FVC, p=0.95), Peak Expiratory Flow Rate (PEFR, p=0.16), Thoracic expansion (TE, p=0.27)/cardiovascular parameters (Systolic Blood Pressure (SBP, p=0.108), Diastolic Blood Pressure (DBP, p=0.17) and Pulse Rate (PR, p=0.93) as well as the respiratory symptoms (SGRQ scores, p=0.11) in all subjects. Conclusion: There was no relationship between thoracic kyphosis and selected pulmonary/cardiovascular parameters as well as respiratory symptoms in patients with COPD and asthma.

In applying SW education for non-major undergraduates, we applied the physical computing lesson using Arduino. There is a case in which the basic problem-solving process teaching method based on the computational thinking was proposed in the physical computing class using Arduino. However, in educating computational thinking process, it is necessary to evaluate and educate understanding of SW structures. After understanding SW structures, it is correct SW education flow to make creative outputs by applying computational thinking process. However, there is a lack of examples of how to evaluate understanding of SW structures in the class using Arduino. In this paper, we proposed a one - semester curriculum for lectures on SW education using Arduino for non-majors. In addition, we proposed and analyzed the evaluation method of the understanding of SW structures and the evaluation problems developed in this course.

Recently, with an emphasis on software proficiency, universities are providing software education to all students regardless of their majors. However, non-majors often lack motivation for software education and perceive the unfamiliar learning content as more challenging. To address this issue, tailored software education according to the learners' characteristics is essential. Art students, for instance, with their strong visual comprehension and expressive abilities, can benefit from utilizing visual literacy to enhance the effectiveness of programming education. In this study, we propose decomposing everyday problems into flowcharts and pseudocode to construct procedural and visual images. Using the educational programming language PlayBot, we aim to analyze the effectiveness of teaching by coding to solve problems. Through this approach, students are expected to grasp programming concepts, understand problem-solving processes through computational thinking, and acquire skills to apply programming in their respective fields.

A 4-year-old, spayed female German Shepherd dog (GSD) weighing 22.4 kg was referred to Chungnam National University Veterinary Medicine Teaching Hospital with the chief complaint of a cardiac murmur. A continuous murmur was detected at the left basilar region upon auscultation. In the thoracic radiographs, slight bulging of the aorta, the main pulmonary artery, and the left atrium were observed. Echocardiography revealed continuous turbulent flow directed from the main pulmonary artery towards the pulmonary valve and consistently within the main pulmonary artery. Based on all the results, a diagnosis of type II A patent ductus arteriosus (PDA) was made, and plans were established to treat it with transcatheter occlusion. Transcatheter occlusion was performed using a vascular plug and successfully deployed at the PDA. The patient did not exhibit any complications. GSDs are relatively less common compared to small-breed dogs in South Korea. Considering that GSDs are predisposed to PDA, it is crucial to periodically assess the presence of PDA through auscultation and echocardiography, even in the absence of clinical signs. Transcatheter occlusion using a vascular plug can be an option for treatment and can yield favorable outcomes.

A 3-year-old, 20.6 kg, neutered male German Shepherd dog was referred to Kyungpook National University Veterinary Medicine Teaching Hospital. Clinical examination revealed chronic diarrhea for 6 weeks and a non-tender, distended abdomen without lethargy, anorexia, and vomiting. Diarrhea was watery and had a waxing and waning course despite symptomatic treatment. A complete blood count identified mild leukocytosis and mild anemia. Serum biochemistry analysis showed elevated alanine aminotransferase and aspartate aminotransferase levels, and mild hypoalbuminemia. Abdominal ultrasound examination revealed mixed echogenicity with absent blood flow at the caudate process of the caudate liver lobe and a small amount of ascites. Computed tomography revealed torsion of the caudate process of the caudate liver lobe and spleen and gas dilatation of the intestine. After establishing a diagnosis of organ torsion on imaging, we deemed the condition an emergency and immediately performed surgery. Given that laparotomy confirmed organ torsion, liver lobectomy, total splenectomy, and prophylactic gastropexy were conducted. The patient was discharged 11 days after surgery without complications. In general, liver lobe torsion and splenic torsion are uncommon in dogs and present with nonspecific clinical signs, such as abdominal pain, lethargy, anorexia, and vomiting. In the current case, torsion of the caudate liver lobe and spleen occurred without other clinical signs except for a distended abdomen. Moreover, no reports in dogs have demonstrated the simultaneous occurrence of both diseases.

Problem solving is important in school mathematics as the means and end of mathematics education. In elementary school, inductive reasoning is closely linked to problem solving. The purpose of this study was to examine ways of improving problem solving ability through analysis of inductive reasoning process. After the process of inductive reasoning in problem solving was analyzed, five different stages of inductive reasoning were selected. It's assumed that the flow of inductive reasoning would begin with stage 0 and then go on to the higher stages step by step, and diverse sorts of additional inductive reasoning flow were selected depending on what students would do in case of finding counter examples to a regulation found by them or to their inference. And then a case study was implemented after four elementary school students who were in their sixth grade were selected in order to check the appropriateness of the stages and flows of inductive reasoning selected in this study, and how to teach inductive reasoning and what to teach to improve problem solving ability in terms of questioning and advising, the creation of student-centered class culture and representation were discussed to map out lesson plans. The conclusion of the study and the implications of the conclusion were as follows: First, a change of teacher roles is required in problem-solving education. Teachers should provide students with a wide variety of problem-solving strategies, serve as facilitators of their thinking and give many chances for them ide splore the given problems on their own. And they should be careful entegieto take considerations on the level of each student's understanding, the changes of their thinking during problem-solving process and their response. Second, elementary schools also should provide more intensive education on justification, and one of the best teaching methods will be by taking generic examples. Third, a student-centered classroom should be created to further the class participation of students and encourage them to explore without any restrictions. Fourth, inductive reasoning should be viewed as a crucial means to boost mathematical creativity.

Three dogs with suspected patent ductus arteriosus were referred to Veterinary Medical Teaching Hospital of College of Veterinary Medicine, Konkuk University because of cough, shortness of breath, exercise intolerance, and syncope, Continuous murmur and thrill were detected in physical examination. Left ventricular enlargement, cardiomegaly, bulged main pulmonary artey were found in radiography. Tall R wave, wide P wave, atrial fibrillation, and turbulent flow were observed in electrocardiogram and echocardiogram. Thoracotomy was performed at left fourth intercostal space under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. The median (mean ${\pm}$ SD) diameter of patents was $8.0{\pm}2.0mm$. The median operation time was $36{\pm}6.6min$. On examination right after surgery, continuous murmur, thrill, atrial fibrillation, and turbulent flow were disappeared. On 30 days after surgery, clinical signs, left ventricular enlargement, and, bulged main pulmonary artery were disappeared. VHS 12.5 and 13.5, R wave 3.3 and 3.0 mV, and P wave 0.05 and 0.05 sec were decreased to 10.0 and 10.5, 1.8 and 2.0 mV, and 0.04 and 0.04 sec respectively in case 1 and 2. Ratio of aorta and main pulmonary artery in diameter was changed 1 : 1.3 and 1 : 1.6 into 1 : 1.1 and 1 : 1 respectively in case 1 and 2. Mild tear developed during dissection in case 3 and hemorrhage was controlled by vascular Devakey forceps. However, the dog died. On 12 months after surgery, patients (case 1 and case 2) have not showed abnormal signs.

This study examined the influencing factors of learning satisfaction for real-time online adult nursing classes to provide basic data for the design and operation of online lectures in nursing subjects and help prepare a new educational paradigm. The subjects of the study were 105 3rd graders taking real-time online adult nursing classes, and data collection was conducted through structured online questionnaires from June 20 to July 30, 2020. The subjects were analyzed using a t-test, one-way ANOVA by Scheffe test, Person's correlation coefficients, and Hierarchical multiple regression analysis. The results showed that the learning flow was 3.07, academic engagement was 3.46, and learning satisfaction was 3.88. Learning satisfaction showed a positive correlation with learning flow (r=.41, p<.001) and academic engagement (r=.56, p<.001). In addition, the factors influencing the learning satisfaction of the subjects of this study were academic engagement (��=.47), very high in the level of interest in adult nursing classes (��=.21), and high (��=.20) followed by 34% (F=14.53, p<.001). Therefore, the learning outcomes of nursing students and the effective achievement of their learning goals are expected by developing plans and teaching methods for active participation in classes.
