This proposed work aims to understand the Korean Academic Circle (KAC)'s research trend on the "One Belt One Road" (OBOR) by employing a quantitative analysis of the recent research articles published by the KAC. To do so, this proposed research has used the well-known network analysis software, Ucinet 6, by which the papers on related topics are collected and filtered from Korea Citation Index. To perform the analytical selection, the proposed work has chosen 'keywords' as the core research object and performed analysis from transverse to longitudinal aspects, and from holistic to individual aspects, respectively; and from this, the KAC's research trend on OBOR is derived. The present work has established that the KAC's attention is continuously increasing on OBOR and has sustainability. Centered on the OBOR, Korean researchers have spread their studies in various dimensions ranging from the issues like China's political economy to Sino-Korea economic and trade exchanges, and so on. The KAC has even combined OBOR with Korea's international development initiatives, which can help Korea benefit from active and sustainable cooperation with China. Moreover, the proposed work has found that Korean researchers have also actively expressed their growing attention, highlighted Korea's interest, and showed concern about China hegemony and Sinocentrism in their recent documented research works.

Purpose: This study is based on the results of previous studies that falls, which is a frequent social problem, causes physical, mental and social health problems in the elderly. In order to identify risk factors for falls in the elderly, this study derives a relationship with oral health and proposes the necessity of oral health care as part of countermeasures to prevent falls in the elderly. Methodology: The final 6,936 people were analysed using the 2018 Korean Longitudinal Study of Ageing(KLoSA) survey data, and the analysis was conducted using the multiple logistic and multiple regression analysis to investigate the relationship between Geriatric Oral Health Assessment Index (GOHAI) and falls experience. Findings: As a result of the analysis in this study, the number of falls experiences and whether or not falls were higher in the elderly female group than in the male group. The likelihood of falls experience has been statistically reduced as Geriatric Oral Health Assessment Index increases by one unit.(OR : 0.991) The number of falls has also been statistically reduced as Geriatric Oral Health Assessment Index increase by one unit.(B : -0.001) Practical Implications: The results of this study, which showed that higher Geriatric Oral Health Assessment Index was lower risk of falls, explained by the connection that oral health may affect nutritional intake, which leads to sarcopenia and physical loss, which in turn increases the risk of falls. As a way to solve the fall problem, efforts should be made to improve the oral health of the elderly, and furthermore, the importance of nutrition management thorugh oral health care of the elderly is increasd.

Purpose: This study aimed to investigate the association of social participation and depressive symptoms with health-related quality of life (HRQoL) among older adults living in urban and rural areas. Methods: This secondary, cross-sectional study was conducted with a total of 66,765 adults aged ≥65 years (urban-26,485 and rural-40,280) who participated in the household and individual surveys of the Korea Community Health Survey 2019. Data on the main study variables including social participation, depressive symptoms, and HRQoL were collected from August 16 to October 31, 2019. Multiple linear regression was used to identify the factors affecting HRQoL in urban and rural older adults. Results: The proportion of social participation (χ²=354.69, p<.001) and the level of HRQoL (χ²=12.06, p<.001) were significantly higher in older adults living in urban area than those in rural area. However, there was no significant difference in depressive symptoms between older adults living in urban and rural areas. Multiple linear regression analysis showed that social participation and depressive symptoms were significant predictors of HRQoL in both urban and rural older adults. Conclusion: Our main finding highlights that active participation in social activities and management of depressive symptoms in older adults regardless of living arrangements are crucial to improve HRQoL in later life. Interventions to increase social participation include early assessment of depressive symptoms in the community to promote HRQoL. More longitudinal studies are needed to identify the factors associated with HRQoL between older adults living in urban and rural areas while considering neighborhood environment and living arrangements.

Purpose: This systematic review aimed to compare the efficacy, defined in terms of the mean percentage of root coverage (mRC), of surgical treatment approaches combined with adhesive restorations of non-carious cervical lesions (NCCLs) to that of root coverage alone in patients with a single gingival recession (GR) and NCCL. Methods: A literature search was conducted to identify longitudinal studies reporting the mRC following treatment for the correction of GR defects associated with NCCLs using a combination of surgical and restorative techniques in systemically and periodontally healthy patients. Results: The search resulted in the retrieval of 12,409 records. Seven publications met the inclusion criteria for the qualitative synthesis of data. The mRCs ranged from 69% to 97%. In the medium term, the gingival margin position was more stable when a connective tissue graft (CTG) was used, independently of whether restoration of teeth with NCCLs was performed. Conclusions: The strength of the evidence was limited by methodological heterogeneity in terms of study design as well as the unit and period of analysis, which precluded a metaanalysis. Although no definitive conclusion could be drawn due to the lack of sufficient evidence to estimate the effectiveness of the interventions, CTG-based procedures contributed to gingival margin stability regardless of the performance of restoration to treat NCCLs.

Purpose: Untreated depression in adolescents affects their entire life. It is important to detect and intervene early depression in adolescence considering the characteristics of adolescent's depressive symptoms accompanied by internalization and externalization. The aim of this study was to identify latent classes of depressive symptom trajectories of adolescents and determinants of classes in Korea. Methods: The three time-point (2018~2020) data derived from the Korean Children and Youth Panel Survey 2018 were used (N=2,325). Latent Growth Curve Modeling (LGCM) was conducted to explore the depressive symptom trajectories in all adolescents, and Latent Class Growth Modeling (LCGM) was conducted to identify each latent class. Multinomial logistic regression analysis was performed to confirm the determinants of each latent class. Results: The LGCM results showed that there was no statistically significant change in all adolescents' depressive symptoms for 3 years. However, the LCGM results showed that four latent classes showing different trajectories were distinguished: 1) Low-stable (intercept=14.39, non-significant slope), 2) moderate-increasing (intercept=19.62, significantly increasing slope), 3) high-stable (intercept=26.30, non-significant slope), and 4) high-rapidly decreasing (intercept=26.34, significantly rapidly decreasing slope). The multinomial logistic regression analysis showed that the significant determinants (i.e., gender, self-esteem, aggression, somatization, peer relationship) of each latent class were different. Conclusion: When screening adolescent's depression, it is necessary to monitor not only direct depression symptoms but also self-esteem, aggression, somatization symptoms, and peer relationships. The findings of this study may be valuable for nurses and policy makers to develop mental health programs for adolescents.

BACKGROUND/OBJECTIVES: Although adherence to a higher diet quality may help prevent cognitive decline in older adults, literature for this in a Korean population is limited. Thus, the aim of this study was to examine the association between diet quality indices and the risk of mild cognitive impairment (MCI) in Korean older adults. SUBJECTS/METHODS: This cross-sectional study included 806 community-dwelling people aged 60 yrs and over in Korea. Diet quality was assessed via the revised Recommended Food Score (RFS) and alternate Mediterranean Diet Score (aMDS). Cognitive function was measured using a Korean version of the Mini-Mental State Examination (MMSE-KC). Associations between diet quality indices and MMSE-KC score were assessed with a general linear model after adjusting for covariates. Logistic regression was used to determine the association between diet quality indices and the risk of MCI. RESULTS: The prevalence of MCI was 35.3%. There were no significant trends between MMSE-KC scores and RFS and aMDS after adjusting for age, gender, education, exercise, living status, social activity, and alcohol drinking. Among total subjects, RFS was inversely associated with the risk of MCI after adjusting for covariates (Q5 vs. Q1; odds ratio [OR], 0.49; 95% confidence interval [CI], 0.28-0.83). Among total subjects and men, aMDS was inversely related to the risk of MCI after adjusting for covariates (Q5 vs. Q1; OR, 0.51; 95% CI, 0.29-0.89 for total subjects; Q5 vs. Q1; OR, 0.36; 95% CI, 0.15-0.83 for men). CONCLUSIONS: Our results demonstrate that high diet quality evaluated by RFS and aMDS is inversely associated with the risk of MCI. Thus, high quality diet may reduce or retard cognitive decline in the old population. Longitudinal studies are needed to determine the causal relationship between diet quality and the risk of MCI in the elderly.
