Purpose: This study is a pseudo-experimental study of design before and after the non-equivalent control group, which was attempted to verify that the application of the ukulele to the elderly has the effects of reducing depression, improving self-efficacy, strengthening social bonding, and improving cognitive function. Methods: 46 (23 in the experimental group and 23 in the control group) participants were selected. The experimental group was provided with three sessions of a music program using eight Ukuleles for the elderly, while the control group was provided with three sessions for the elderly. IBM SPSS 25.0 was used for data analysis, and the independent t-test, 𝑥²-test, and Fisher's exact probability test were performed to verify the homogeneity of the subject's general characteristics. The effect verification after the experimental treatment was analyzed by Fisher's exact probability test, Friedman test, and Mann-Whitney U test. Results: Depression showed a statistically significant difference between the two groups (F=39.88, p<.001), self-efficacy showed a statistically significant difference between the two groups (z=-4.96, p<.001), social bonding showed a statistically significant difference between the two groups (z=-5.19, p<.001), and cognitive function showed a statistically significant difference between the two groups (z=-3.98, p<.001). Conclusion: It was found that the 'Music Program using the Ukulele' was effective in reducing depression of the elderly, improving self-efficacy, reinforcing social bonding, and improving cognitive function. We hope that the Music Program using the Ukulele can be used in the elderly nursing curriculum in the future, and we suggest it should be applied as a nursing intervention to those who are experiencing cognitive decline.

Purpose - The purpose of this study is to analyze Korea's trade relations centered on the Pacific Alliance (PA), a major economic integration in Latin America, and identify its problems and suggest measures that can be taken by the government and corporations to reinforce economic cooperation. Design/methodology/approach - To improve the level of contribution of the study, an empirical analysis is necessary. However, due to limited data access, the study will approach the topic of trade relations between Korea and the PA with various statistics and literature. Findings - First, there is an urgent need for changes in import-export goods between Korea and the PA, as trade is focused on specific items. Second, although foreign direct investment from Korea to the PA is centered in manufacturing and mining industries, there should be different investment strategies by countries and industries. Third, it is necessary to reinforce commercial cooperation. Korea currently has Free Trade Agreements with Chile, Peru, and Columbia, but not with Mexico, the largest trading partner among the PA. Therefore, Korea must take active measures to sign an FTA with Mexico, which has been put on hold. Research implications or Originality - Latin America has the most thriving market when it comes to Free Trade Agreements worldwide. With the official establishment of the Pacific Alliance (PA) in 2012, the economic integration of Latin America faced entirely new circumstances. Reinforcing economic cooperation with the PA is extremely important for Korea in terms of entering and dominating the Latin American market. However, there is still a lack of research on the Pacific Alliance, and corporations that aim to enter the Latin American market face difficulties due to lack of information. By investigating the Pacific Alliance and its prospects and analyzing the trade relations with Korea, this study will provide strategic measures for corporations that wish to enter the Latin American market.

In this paper, we propose BCON, a service that allows individuals to store personal contents safely, and reliably guarantee their ownership of contents, certifying their identities with DIDs(Decentralized identifiers). DID technology, which supports decentralized identification service based on a blockchain that cannot forgery or alter data, allows users to selectively provide their information, controlling personal information and reinforcing their sovereignty over their identity. BCON stores information about the content specified by a user on the blockchain and Authenticates the user's identity based on DID technology. It also provides functions for the user to safely upload and download the user's content to a distributed database. BCON consists of the content service verifier, the content storage service, the content management contract, and the user application, administrating rhe DID registry for Authority management.

There have been constant requests for urgently recruiting professionals in the archives to establish archival management systems by reflecting public institutional feature as well as reinforcing expertise and independence of them. However, it is true that some even adequate professional manpower haven't been secured at each level of public institutions due to ambiguous standards for the placement of professionals in the field of records management followed by the current [Public Records Management Act]. Thereupon, this study is to create records management task model for the archival management institutions with the workload of records management induced by the model, and to present reasonable scale of workforce to deal with the assignment. Moreover, here is shown which professional staff should be allocated for better efficiency and systems to carry out the task of records management in each relevant institution.

We posit that employee ownership through defined contribution (DC) plans results in managerial entrenchment, and then examine the effect of the enactment of the Pension Protection Act of 2006 on the relation between the employee ownership and firm performance. By conducting Ordinary Least Square regression with the data from Form 5500 over the period of 1999-2014, we find that firms with large employee ownership increase their firm value measured by Tobin's Q after the adoption of the Act. These findings suggest that the adoption of the Act has been effective to mitigate the negative effect of managerial entrenchment by decreasing the employee ownership and reinforcing the fiduciary duty of plan trustees. Given the fact that we test the effects of the diversification rule on employee ownership using firm performance, further research could aim to examine the effects of the rule on employee ownership using stock return or market reaction.

The purpose of this study was to investigate levels of perception of good death and hospice, and attitude of dying care, to examine relationships among them, and then to investigate predictors affecting of attitude of dying care in nursing students. The participants were 229 nursing students in D city who were surveyed in May to June 2019 using self-report questionnaires. Perception of good death and hospice, and attitude of dying care were related positively among variables. In the multiple regression analysis, perception of good death, and perception of hospice were influential factors significantly associated with the attitude of dying care. Those factors explained 39.3% of the attitude of dying care in nursing students. The most important factor was perception of hospice. In order to encourage and improve positive perception of death and attitude of dying care in nursing students, nursing educators should consider building up and reinforcing the curriculum of nursing college.

Purpose: Zirconia is differentiated from other ceramics because of its high resistance to corrosion and wear, excellent flexural strength (900~1400 MPa), and high hardness. Dental zirconia with proven mechanical/biological stability is suitable for the manufacture of implants. However, there are limited in vivo studies evaluating stress distribution in zirconia compared with that in titanium implants and studies analyzing finite elements. This study was conducted to evaluate the stress distribution of the supporting bone surrounding zirconia and titanium implants using the finite element analysis method. Methods: For finite element analysis, a single implant-supported restoration was designed. Using a universal analysis program, eight occlusal points were set in the direction of the occlusal long axis. The occlusal load was simulated at 700 N. Results: The zirconia implant (47.7 MPa) von Mises stress decreased by 5.3% in the upper cortical bone compared with the titanium implant (50.2 MPa) von Mises stress. Similarly, the zirconia implant (20.8 MPa) von Mises stress decreased by almost 4% in the cancellous bone compared with the titanium implant (21.7 MPa) von Mises stress. The principal stress in the cortical and cancellous bone exhibited a similar propensity to von Mises stress. Conclusion: In the supporting bone, the zirconia implant is able to reduce bone resorption caused by mechanically transferred stress. It is believed that the zirconia implant can be a potential substitute for the titanium implant by reinforcing aesthetic characteristics and improving stress distribution.

Purpose: Aromatase inhibitors (AIs) are widely prescribed for postmenopausal women with breast cancer and are known to cause musculoskeletal pain. This study aimed to identify factors associated with AI continuation intention among breast cancer survivors (BCS). Methods: A cross-sectional survey was conducted on 123 BCS (stages I-III), who had been taking AIs for at least 6 weeks. Participants were recruited from a cancer center in Goyang, Korea, from September to November 2019. Descriptive statistics, Welch analysis of variance, Pearson correlation coefficients, and simple linear regression were used for the analysis. Results: Beliefs about endocrine therapy was a significant predictor of AI continuation intention (β=.66, p<.001). The majority of participants (87.0%) reported experiencing musculoskeletal pain since taking AIs and the score for the worst pain severity within 24 hours was 5.08±2.80 out of 10. Musculoskeletal pain, however, was not associated with AI continuation intention. Fear of cancer recurrence (FCR) was clinically significant (≥13) for 74.0% of the respondents (mean, 17.62±7.14). Musculoskeletal pain severity and pain interference were significantly associated with FCR (r=.21, p<.05; r=.35, p<.01, respectively). Pain interference was significantly associated with beliefs about endocrine therapy (r=-.18, p<.05). Conclusion: AI continuation intention can be modified by reinforcing patients' beliefs about endocrine therapy. Musculoskeletal pain may have a negative effect on beliefs about endocrine therapy and increase FCR among BCS. Thus, awareness of musculoskeletal pain during AI therapy should be raised and further research is required to develop multidisciplinary pain management strategies and clinical guidelines to reinforce beliefs about endocrine therapy.

The purpose of this study was to reconsider existing hypotheses on the orinination and changes of changbang-anchogongs and their types and suggest an alternative hypothesis. The earliest changbang-anchogongs in $17^{th}$ century is presumed to originate as imitations of chungbang ppaelmoks for ornamental and reinforcing parts for changbangs. They were framed whole sides of buildings equally, and were used in small numbers of extant royal buildings and Buddhist halls. From late $17^{th}$ century, enlarged dragon shape changbang-anchogongs applied to Buddhist halls maily to decorate and strengthen front side of buildings. As a result of exchange between changbang-anchogongs and Ikgong type brackets, combined changbang-anchogongs in Buddhist halls were invented for stronger connection with upper bracketing units and have been spread during $18^{th}$ century. Danpyeongbang anchogongs were originated by the connection between short pieces of pyeongbangs and early type of anchogongs similar to ppaelmoks. They belong to minority subtype, but were drawn in illustrations by mistake, as parts of main halls of royal palaces from $19^{th}$ century, because of painter's confusion about new techniques for changbang-anchogongs. Combined changbang-anchogongs for royal buildings were presumed to be invented in 1790s by stimulation from a Buddhist hall related to royal tomb. However, unlike Buddhist precedence, they were used to reinforce and decorate whole sides, even corners, of buildings, and their frameworks and shapes were imported from Daeryang-anchogongs at flanks of ritual halls in royal tombs and royal shrines from $17^{th}$ century.
