The purpose of this study was to investigate the effects of group combined intervention that combined animal-assisted therapy and integrated elderly play therapy on the depression, self-esteem, and emotional expression of geriatric patients residing in nursing homes. This was achieved by providing cognitive, physical, and emotional activities and social interaction at the same time. The group combined intervention method was applied to twelve elderly patients (six in the control group, six in the experimental group) aged 65 or older who live in a nursing home for the elderly in C province, from May 3, 2019 to June 21, 2019, for a total of 8 times (once a week, 50 minutes at a time). The quantitative evaluation was analyzed through SPSS 21.0 for comparison before and after the program was implemented, using the Korean version of the depression and the self-esteem scale. The qualitative evaluation compared emotional expression pre-test and post-test. The major results of the study were as follows: First, the group combined intervention was effective in reducing depression levels of the experimental group among the elderly patients. Second, it was effective in improving the self-esteem of the experimental group among the elderly patients. Third, it showed a significant difference in the emotional expression of the experimental group among the elderly patients. Therefore, it was found that group combined intervention reduces depression and improves self-esteem and emotional expression of the elderly. Based on these results, it is hoped that this study will be a cornerstone in the development of concrete programs for the benefit of elderly patients living in facilities.

A design methodology for transformers including integrated and center-tapped structures for LLC resonant converters is proposed. In the LLC resonant converter, the resonant inductor in the primary side can be merged in the transformer as a leakage inductance. And, the absence of the secondary filter inductor creates low voltage stress on the secondary rectifiers and is cost-effective. A center-tapped structure of the transformer secondary side is widely used in commercial applications because of its higher efficiency and lower cost than full-bridge structures in the rectifying stages. However, this transformer structure has problems of resonance imbalance and transformer inefficiency caused by leakage inductance imbalance in the secondary side and the position of the air-gap in the transformer, respectively. In this paper, gain curves and soft-switching conditions are derived by first harmonic approximation (FHA) and operating circuit simulation. In addition, the effects of the transformer including integrated and center-tapped structures are analyzed by new FHA models and simulations to obtain an optimal design. Finally, the effects of the air-gap position are analyzed by an electromagnetic field simulator. The proposed analysis and design are verified by experimental results with a 385W LLC resonant converter.

Controlled pore glass bead was modified with bovine serum albumin (BSA), and glutathione (GSH) was immobilized through three kinds of linkers on top of BSA. Bis(3-sulfo-N-hydroxysuccinimide suberate) sodium salt $(BS^3)$, N-hydroxysuccinimide 3-(2-pyridyldithio)propionate (SPDP), or N-hydroxysuccinimide 4-maleimidobutyrate (GMBS) was introduced into the BSA-bound matrix. Subsequently, GSH was immobilized by addition of thiol side chain into the maleimido moiety, replacing a disulfide group, or formation of an amide group upon releasing 3-sulfo-N-hydroxysuccimide group. It was observed that conjugation methodology played a critical role for activity of the immobilized GSH. SDS-PAGE chromatogram showed that the matrix of glutathione immobilized on BSA through GMBS manifested high selectivity towards glutathione-S-transferase (GST) in cell lysate.

Objectives: The aim of this study was to determine distribution patterns of TOAST subtypes of ischemic stroke patients admitted to oriental hospitals and to get a better understanding of present conditions in oriental medicine by comparing with the Korea stroke registry (KSR), the largest and representative data. Methods: Clinical data were collected from acute ischemic stoke patients. MRI studies including vascular images were performed in all cases. TOAST criteria were used to determine subtypes of ischemic stroke patients. According to the duration from disease onset to hospital admission time, patients were assigned to 3 groups (Group I0 to 3 d, Group II4 to 7 d, Group III8 to 28 d) and the distribution of TOAST subtypes were compared among these three groups. Results: We collected 514 sets of clinical data from 10 oriental hospitals between May 2007 and September 2009. Small vessel occlusion (SVO) subtype was the most common (57.62%), followed by large artery atherosclerosis (LAA, 29.98%). Compared with TOAST distribution of KSR, the proportion of ischemic stroke patients with SVO subtype was higher than that of KSR. On the other hand the proportion of patients with stroke of undetermined etiology (SUE) was lower. Distributions of SVO, LAA and cardioembolism (CE) in group were I 66.4%, 23.8% and 8.9%, respectively; those in group IIIwere 51.03%, 34.71% and 11.57%, respectively. Conclusions: In oriental hospitals, the proportion of ischemic stroke patients diagnosed as SVO type was higher than that of KSR. At early stage (from onset to 2 d) proportion of SVO was very high, however after 7 days from onset it decreased with concomitant increases in proportions of LAA and CE. These phenomena may be due to the facts that 1) at early stage emergency treatments are limited in oriental hospitals, 2) after early stage many patients prefer oriental treatments, including rehabilitation.

The longitudinal integrated clerkship is an innovative approach in medical education that emphasizes continuity as a key principle to provide student-centered experiences and learning. Seoul National University College of Medicine decided to adapt longitudinal integrated clerkships to the new curriculum beginning in 2018, and therefore conducted pilot studies in 2016 and 2017. This study aimed to analyze the program evaluation results of the two pilot programs and discuss issues related to the successful implementation of longitudinal integrated clerkships in Korea. We conducted a focus group interview with nine students who participated in the 2016 pilot program and 13 students who participated in the 2017 pilot program. We also conducted a focus group interview with 11 faculty members who either participated in the pilot program or will participate in the main program. From the 2016 experience, we found that it is not appropriate to assign each patient to a single student and let the students contact their patients personally for feasibility and safety reasons. In the 2017 pilot program, we assigned each patient to a group of students, which made it more feasible for the students to follow-up with their patients. The students were satisfied with their new experience of longitudinal patient follow-up and regular meetings in the pilot program. Faculty emphasized the importance of establishing the course objectives and holding an orientation for the students and the faculty. Further study is planned to evaluate the early outcomes of the main longitudinal integrated clerkship.

The aim of this study was to analyze the empathy represented in the learners' group journal of integrated English class using literature. 15 high school students participated in this class. In this study, integrated English class using literature was carried out by supplementing the point that amount of the English classes using literature had been focused on reading activities. In addition, not only communicative abilities but also learners' empathy to the main character in the literary was taught. In order to analyze the empathy expressed in learners' group journal, the integrated English class using literature was conducted in the second period and the class was recorded by video. The empathy was based on the community competence mentioned in the 2015 revised curriculum, and learners were asked to write the group journal. As a result of the research, the learners showed an understanding of the context in the novel and learners' group journal showed that their empathy to the main character in the novel. It is expected that the data on the empathy represented in the learner group journal of the integrated English class using literature will be used in English class.
