The objective of this study is to survey Social Participation of the Elderly's quality of life according to their activity levels and examine the differences by their gender and age. The subjects of this study were elderly aged 60 or older who are living in the metropolitan area and those reportedly participating in various social activities at the time of the survey. A total of 586 cases were used for the analysis. Data were analyzed through multi group analysis using a structural equation model, and AMOS 7.0 was used in statistical processing. The results of this study showed that, first, the quality of life was significantly and positively affected by flow experiences in economic participation, social fellowship participation, and self development participation. Second, the results of multi group analysis on the relations between the social participation level and the quality of life according to gender demonstrated that the there were gender differences on the full path model, and that there were significant differences in relationships between the volume of social fellowship participation and the quality of life between men and women. Third, a similar finding was found for the age group that the paths between flow experiences in economic participation and the quality of life significantly differed by age groups. Based on these findings, implications for theory and practice were discussed.

Background: In recent years, introduction of novel immunosuppressive agents and its proper implementation for clinical practice have contributed to improving clinical outcomes of kidney transplantation (KT). Here, we report clinical outcomes of KTs and related risk factors. Methods: From July 1998 to June 2016, 354 KTs (182 from living and 172 from deceased donors) have been performed at Ulsan University Hospital. We retrospectively reviewed the clinical characteristics and outcomes of KT recipients, then estimated graft and patient survival rate were estimated and analyzed risk factors using Cox-regression. Results: The median follow-up period was 53 months (range; 3 to 220 months). The mean ages of recipients and donors were 45.0 years (SD, 12.5) and 44.7 years (SD, 13.6) years, respectively. During follow-up, 18 grafts were lost and 5- and 10-year death-censored graft survival was 96.7% and 91.5%, respectively. Biopsy-proven acute rejection (BPAR) occurred in 71 patients (55 cases of acute cellular rejection and 16 of antibody-mediated rejection). Cox-regression analysis showed that BPAR was a risk factor related to graft loss (hazard ratio [HR], 14.38; 95% confidence interval [CI], 3.79 to 54.53; P<0.001). In addition, 15 patients died, and the 5- and 10-year patient survival was 97.2% and 91.9%, respectively. Age ≥60 years (HR, 6.03; 95% CI, 1.12 to 32.61; P=0.037) and diabetes (HR, 6.18; 95% CI, 1.35 to 28.22; P=0.019) were significantly related to patient survival. Conclusions: We experienced excellent clinical outcomes of KT in terms of graft failure and patient survival despite the relatively high proportion of deceased donors. Long-term and short-term clinical outcomes have improved in the last two decades.

As the importance of the environment has been recognized worldwide, the need to calculate and reduce carbon emissions has been drawing an increasing attention throughout various industrial sections. Thereby the discipline of LCA (Life Cycle Assessment) involving raw material preparation, production processes, transportation and installation has been established. There is a clear research gap between the need and the practice for Korean Case of renewable energy industry, particularly wind power. To bridge the gap, this study conducted LCA research on wind power generation in the Korean area of Yeongdeok, an example of a domestic onshor wind power complex using SimaPro, which is the most widely used LCA system. As a result of the study, the energy recovery period (EPT) of one wind turbine is about 10 months, and the GHG emitted to generate power of 1 kwh is 15 g CO₂/kWh, which is competitive compared to other energy sources. In the environmental impact assessment by component, the results showed that the tower of wind turbines had the greatest impact on various environmental impact sectors. The experience gained in this study can be further used in strengthening the introduction of renewable energy and reducing the carbon emission in line with reducing climate change.

Purpose: In order to increase the quality of nursing care for patients with diabetes mellitus, it is important for clinical nurses to accept changes in diabetes knowledge and correct their approach immediately. This approach will also contribute to effective nursing practice. Methods: The study was designed to investigate the level of knowledge and diffusion of knowledge for nursing care of patients with diabetes mellitus among clinical nurses. It was conducted with nurses from 29 general hospitals in Korea from November 3 to December 5, 2008. The questionnaire consisted of 129 items and it was sent to the participants by mail. Of the 1,060 questionnaires returned, only 930 were valid for use in the statistical analysis. Results: 1) The average score for clinical nurses' knowledge of diabetes mellitus was 0.67 out of 1.0. 2) The level of persuasion of knowledge for nursing care of patients with diabetes mellitus averaged 0.64 out of 1.0 3) The level of practical application of knowledge for nursing care of patients with diabetes mellitus averaged 1.05 out of 2.0, indicating that they applied their knowledge 'sometimes'. 4) The level of diffusion of knowledge for nursing care of patients with diabetes mellitus was 2.37 out of 4.0 and level was estimated as the stage of 'persuasion'. 5) There were significant differences in nursing knowledge of diabetes mellitus, according to experience in practical education for diabetes mellitus. Conclusion: The results indicate that nurses with a lower level of knowledge of diabetes mellitus have a lower level of persuasion of knowledge for nursing care of patients with diabetes mellitus and lower practical application. To improve the level of nurses' knowledge of diabetes mellitus, practical training programs are needed for areas in which knowledge level is low, such as 'diagnosis and management of diabetes mellitus', 'oral diabetes medication', and 'glucose control in special conditions'.

Metaverse is one of the most frequently used words recently, with digitalization accelerated by the COVID-19 pandemic that started in 2019 and the development of information and communication technology. It is expected to bring a new revolution in our life as a whole in user experience. In particular, as telecommuting was adopted in the business area, interest in virtual office services such as digital video conferencing and remote offices, which are similar to the metaverse, has also increased. In this study, a study on the intention to use the metaverse service used in the work environment was applied to the Unified Theory of Acceptance and Use of Technology 2(UTAUT2). External variables for metaverse characteristics, such as self-presentation, telepresence, and technostress, were analyzed and discussed. In this study, PC-based Gather.town and VR-based Facebook Horizon, currently the most well-known and considered usable in work environments, were introduced to potential users and conducted a survey. This study has academic implications in that the research has examined the factors that affect the technology acceptance intention of users who want to apply the metaverse as a work environment based on the UTAUT2 model, unlike previous studies that have been mainly researched on the general metaverse. In practice, it may be helpful to suggest factors that should be considered when firms adopt the metaverse for business purposes.

Purpose: Despite continuous updates of standard treatment guidelines for acute ankle sprain and chronic ankle instability (CAI), in practice preferred treatment protocols vary widely. Based on a Korean Foot and Ankle Society (KFAS) member survey, this study reports current trends in the management of ankle ligament injuries. Materials and Methods: A web-based questionnaire containing 34 questions was sent to all KFAS members in September 2021. Questions mainly addressed clinical experience and preferences for the diagnosis and treatment of ankle ligament injuries. Answers with a prevalence of ≥50% among respondents were considered to reflect tendencies. Results: Eighty-four of the 550 members (15.3%) responded. Answers that showed a tendency were as follows: commonest additional image study (ultrasound), conservative treatment modality (immobilization, oral medication), frequency of surgical treatment (<5 cases per annum), most important factor when deciding on surgical treatment (activity level, e.g., occupation or sport), and commonest surgical procedure (open ligament repair). Answers that showed a tendency for CAI were as follows: most important symptom (repeated sprain, giving way), radiological factors (talar tilt, osteochondral lesion, anterior talar translation), and patient factors (occupation, sports activities, recurrent instability after surgery, etc.). For decision making regarding surgical treatment and method, the most preferred surgical procedure was the modified Broström procedure, and the most common repair technique was suture anchor technique. The following were considered poor prognostic factors; generalized laxity, failed previous surgery, cavovarus, severe mechanical instability, heavy work, obesity, and dissatisfaction after surgery because of residual pain. Conclusion: This study updates information regarding current trends in the management of ankle ligament injuries in Korea, and reveals consensus opinions and variations in approaches to patients with an acute or chronic injury. The divergence of approaches identified indicates the need for further studies to determine standard guidelines and long-term results.

In relation to differentiated mathematics education, Russia has a longer experience in research and practice than Korea. The mathematics curriculum for 10-11 grades currently in use in Russia is a level-specific curriculum and consists of a basic level and an advanced level. And in Russia mathematics textbooks for 10-11 grades are also textbooks for each level. In this study, we analyzed basic level textbook and advanced level textbook written by the same author group among the textbooks 'Algebra and Introduction of Mathematical Analysis' of the 10th grade in Russia. To analyze the main learning contents and textbook descriptions that were added in advanced level the 'real numbers' and 'complex numbers' sections were studied. The main contents of basic and advanced level textbooks for 'functions', 'trigonometric functions', 'trigonometric equations', 'conversions of trigonometric expressions', and 'derivatives', which are included in both basic and advanced textbooks were compared and analyzed, and the descriptive characteristics of the definitions and theorems presented in the two levels of textbooks were also compared and analyzed. From the results of this study, it is expected that various information on the contents of various level textbooks of mathematics, the differences between textbooks for each level, and strategies for the composition of textbooks for various level can be accumulated.

The purpose of this study is to examine the perception of early childhood teachers on ecological art activities oriented to education for sustainable development. The research results are as follows. First, Early childhood teachers recognized the visual art of natural media, the pursuit of community values, and the participation and communication of social members as educational significance of ecological art activities. And difficulties in practicing ecological art were recognized as lack of educational environment, lack of ecological art teaching materials and specific examples, and teachers' lack of understanding of ecological art. Also, they recognized that ecological art activities foster core competencies in art experience area, such as nature-friendly communication skills, eco-friendly sensibility, and creative convergence skills. Second, regarding ecological art activities and sustainable development education, early childhood teachers considered the difficulties in practice as lack of awareness about sustainable development, lack of play meia and materials, lack of educational policies and support, and insufficient teacher training programs. Also, regarding the SDGs that can be practiced in ecological art activities, teachers were found to be highly aware of 'grow affordable and clean energy', 'improve clean water and sanitation', 'provide quality education' in the order. In the contents of education for sustainable development that can be practiced in ecological art activities, teachers are given the order of 'climate change response', 'clean energy', 'water and sanitation', 'quality education', 'health and well-being' and 'marine ecosystem'. was highly recognized. If an ecological art activity program is developed, the rate of responding that it will be used is high, so it is considered that the development of an ESD-oriented ecological art activity program is urgent.

Coercive treatment in mental health has undergone an immense period of philosophical and clinical debate and yet it remains as a highly important issue in which ideology and practice contradict each other. this study focused on the perceived coercion of the persons with mental disorder and analyzed how the characteristics of mental disorder(psychiatric symptoms, psycho-social functions, insight, and the degree of awareness on the need for treatment) and experiences in the process of hospitalization (legal status, coercive measures, and procedural justice) can predict perceived coercion. The participants of this study were 302 patients that has been hospitalized in the psychiatric ward within the period of 4 weeks. 195 participants(64.6%) were male and 106(35.1%) participants were female. MAES, BPRS, GAF, Insight, Legal Status, Coercive Measures, and Need for Treatment were measured. Regression analysis was used to analyze how much perceived coercion can be predicted by characteristics of mental disorder such as the patients' BPRS, GAF, insight, and need for treatment. As a result it showed that among the characteristics of mental disorder insight and awareness of the need for treatment were the main predictors and the characteristics of experiences during hospitalization such as procedural justice, coercive measures, and legal status all displayed significant predictability. As well as implications of results in a practical method of intervention to reduce perceived coercion, the paper discussed issues for limitations and future consideration.
