This study aims to gain insight through understanding the Metaverse, which has recently become a hot topic. The study utilizes the methods of case study and News Bigdata Analysis Services. The Metaverse can be defined as a world with no separation between the virtual and real worlds. Currently, the Metaverse is dominated mainly by the MZ generation, but just like smartphones have quickly entered our lives, the Metaverse will soon, too, become a part of our lives. To follow up on this change, all companies, including global companies, are going after the Metaverse. Today, the Metaverse is successfully being used in all types of fields, including gaming, performing arts, business, etc., and its essential technologies include VR/AR/MR/XR and AI. This study intends to help understand the Metaverse through a case analysis of Zepeto, which has 200 million users worldwide. On Zepeto, users can decorate their own avatars, hang out with friends, go to art galleries and performances, and create and sell items. Of these users, 90% are from outside of South Korea, and 80% are teenagers. With most of the users being underage, many legal and social problems also follow. Nevertheless, who will be the first to conquer the new world of the Metaverse will continue to be a big issue. This study also analyzes domestic news articles about the Metaverse by utilizing the BigKinds system. Starting in 1996, the number of articles about the Metaverse each year remains single digit, until in 2020 when the number sharply rises to 86 news. As of June 2021, there are 1,663 articles on the Metaverse. This study suggests that the Metaverse should now be carefully examined and closely followed.

The suggestions that follow are about the plan for the cooperation between private security and local government and the enhancement of its service for facing the change of public peace environment. Fist, by a local government collecting funds, the business for revitalization of local economics should be done to enhance local economic independence. Second, the autonomous right of a local government should be reinforced and the center for taking complete charge of local security should be established in the self-governing body. Third, the private security should be connected with the local characteristics, the role of which enlarged as well. For this developing the model of security service for the local area and working together between private security and police should be achieved. Fourth, it is necessary for a local government to entrust the private security with its public security service. For this it should be achieved to set up the range of local security service and inform local residents of the advantage of security service entrusted to private security. Finally, in connection with the new system of local police, it is necessary to have clear grasp of the work related to the private security among local police services and private security business and local police should take partial charge of the public peace service.

This study analyzed the influence of cultural empathy and analysis on the cultural sensitivity and understanding of multicultural education and the relationship between the attitudes and cultural empathy and understanding of multicultural education and the multicultural sensibility and attitudes of pre-service early childhood teachers. We conducted a survey on cultural sensitivity, multicultural education and understanding attitude among Early Childhood Education College and enrolled 165 infants with pre teachers in pre-service early childhood teachers who are able to sympathize with cultural areas of the Y. The data were subjected to Pearson correlation analysis with multiple regression analysis performed using the SPSS 21.0 program. From the data analysis, first, cultural empathy and multicultural sensitivity showed a significant positive correlation with understanding and attitudes of multicultural education pre-service early childhood teachers. Second, cultural empathy of the pre-service early childhood teachers was a significant variable for predicting the susceptibility multicultural, multicultural education and understanding attitude. Since cultural empathy can change according to various factors, future investigation of these factors is needed to increase the cultural sensitivity of pre-service early childhood teachers by conducting follow-up studies that apply these findings to educational programs. Cultural empathy shouldn't be limited to multicultural education or simply a means to access the field of experiencing the arts, but should be expanded to include research in teaching and learning on how cultural empathy can be applied to the overall educational curriculum.

Background: The aim of this study was to investigate inhaler device handling in elderly patients. Inhaler devices with respect to misuse and error correction were also compared. Methods: Inhaler use technique was assessed using standardized checklists at the first visit and 3-month follow-up visit after retraining. The primary outcome was difference in the acceptable use ratio among inhaler devices. Secondary outcomes included differences in error correction, the most common step of misuse, and factors affecting the accuracy of inhaler use. Results: A total of 251 patients (mean age, 76.4 years) were included. The handling of 320 devices was assessed in the study. All patients had been trained before. However, only 24.7% of them used inhalers correctly. Proportions of acceptable use for Evohaler, Respimat, Turbuhaler, Ellipta, and Breezhaler/Handihaler were 38.7%, 50.0%, 61.4%, 60.8%, and 43.2%, respectively (p=0.026). At the second visit, the acceptable use ratio had increased. There were no significant differences among inhaler types (Evohaler, 63.9%; Respimat, 86.1%; Turbuhaler, 74.3%; Ellipta, 64.6%; and Breezhaler/Handihaler, 65.3% [p=0.129]). In multivariate analysis, body mass index, Turbuhaler, and Ellipta showed positive correlations with acceptable use of inhalers, whereas Chronic Obstructive Pulmonary Disease Assessment Test score showed a negative correlation. Conclusion: Although new inhalers have been developed, the accuracy of inhaler use remains low. Elderly patients showed more errors when using pressurized metered-dose inhalers than using dry powder inhalers and soft-mist inhalers. However, there were no significant differences in misuse among inhaler devices after individual training. Results of this study suggests that repeat training is more important than inhaler type.

Objective : To investigate nationwide statistics on flow-diverting stent usage for cerebral aneurysm treatment and related mortality data. Methods : We requested data extraction from the National Health Insurance Service claims database using electronic data interchange codes (J3207064, J3207073). Patient and hospital information as well as death statistics were collected from the database. Results : A total of 169 procedures were performed using flow-diverting stents for cerebral aneurysm treatment from November 2014 to December 2016 in Korea. The majority of primary diagnosis was unruptured intracranial aneurysm. During the study period, nine subjects died, including one patient initially diagnosed with subarachnoid hemorrhage. The crude mortality rate was 5.3%. Five patients died within one month after the procedure; therefore, the estimated periprocedural mortality rate was $3.0{\pm}1.3%$. The mortality rate as of the last day of 2016 was $6.3{\pm}2.1%$. Conclusion : In a 171 person-year follow-up in a Korean series, nine deaths occurred after flow-diverting stent treatment. The crude mortality rate in Korea (5.3%) was higher than that reported in a previous meta-analysis (3.8%).

This article intends to discuss about the strategies and methods that the Korean library community should follow to make the ongoing experiment of 'bibliotherapy program' be successful, and eventually, settle up as a regular library service program. The main focus of discussion was on figuring out both theoretical foundations and historical roots that can justify such an experiment in Korean libraries. To the end, a comparative analysis to Readers' Advisory Services was conducted, and also done for comparing the special features in Korean libraries with those of American libraries, especially as related to library services to readers. The final suggestion includes the tasks that Korean LIS scholars should undertake to make the ongoing bibliotherapy experiment become an indigenous Korean model for library services.

The proportion of people who reported unmet healthcare needs is an important indicator to measure the access problem in healthcare service. To examine current status and trends of unmet needs in Korea, we used data from four sources: the Korea National Health and Nutrition Examination Survey (KNHNES, '2007-2015); the Community Health Survey (CHS '2008-2015); the Korea Health Panel Survey (KHP '2011-2013); the Korean Welfare Panel Study (KOWEPS '2006-2015). The proportion of individual reporting unmet healthcare needs as of 2015 was 12.6% (KNHNES), 11.7% (CHS), and 16.3% (KHP, as of 2013). Annual percent change which characterizes trend for follow-up period was -9.4%, -3.4%, and 7.6%, respectively. The proportion of individual reporting unmet healthcare needs due to cost was 2.8% (KNHNES), 1.7% (CHS), and 4.6% (KHP). The proportion of household reporting unmet healthcare needs due to cost was 1.2% (KOWEPS). Annual percent change was -9.0%, -14.9%, 9.4%, and -18.2%, respectively. Low income population reported about 5 times more unmet needs than high income population. Therefore for decreasing the unmet healthcare needs, strategies focusing on low income population were needed.
