This study was conducted to confirm the effect of vibration on muscle activity in IASTM. The subjects were 20 healthy adults. The intervention applied in this study was IASTM applied to the biceps brachii muscle. In the case of the experimental group, unlike the control group, the vibration function was turned on when IASTM was applied. The interventions for each group were applied, and the muscle activity of the biceps brachii muscle was measured before and after the intervention. All measured values were calculated as %MVIC values, dependent t test and independent t test were performed and analyzed for comparisons. As a result of this study, only in the control group, the muscle activity of the biceps brachii muscle after the intervention was significantly decreased compared to before the intervention. When vibration is applied together with IASTM, the relaxation effect is reduced, which is considered to be inappropriate for treatment.

Due to the recent advancements of mobile telecommunication technology and high mobile phone penetration rate, researches on emergency text alert service for enhancing the accessibility have been actively conducted. The worldwide spread of COVID-19 further accelerates the efforts for the alert services. Existing emergency text services are simple and efficient. However, unclear reception area may cause unintended alert messages frequently. In this paper, we analyze survey results regarding the 5G-based text-alert services to derive service requirements for technological advancement. Then we propose an emergency disaster text service scenario using Active Geo-Targeting that enables active disaster text reception of terminals. In addition, we newly define an interface protocol that is CIB(Control Information Block) to operate the proposed scenario.

The purpose of this study was to understand the knowledge structure through keyword network analysis for the purpose of identifying research trends in the research field of multicultural education. To this end, the research trends and intellectual structure of multicultural education were identified through network analysis of words that appeared more than 6 times in the keywords of the papers registered in the KCI (Korean Journal of Citation Index) from 2002 to 2020. Study changes were analyzed by analysis. As a result of the analysis, the first period (2002-2010) focused on multicultural society and multiculturalism, while the second period (2011-2015) additionally introduced multicultural families, globalization, and teacher education, and the third period (2016-2020), multicultural receptivity, multicultural sensitivity, and multicultural efficacy were newly revealed. The research trend of multicultural education in Korean society over the past 19 years has been confirmed that the research topic has changed from theoretical research to empirical research, and the content of multicultural education has also been specified and expanded by field and subject.

The aim of this study was to evaluate the difference of self-care and self-efficacy before and after childbirth in pregnant women with diabetes mellitus. Data were collected from 24 May 2018 to 23 May 2020 for 40 pregnant women over the 24th week of pregnancy. The collected data were analyzed by matched paired t-test using the SPSS 27.0 software program. 27 subjects (67.5%) were under the age of 35, and 13 subjects (32.5%) were over the age of 35. Self-care and self-effectiveness scores were lower in postpartum than in prenatal, which was statistically significant (p< .000). Therefore, it is necessary to develop a nursing intervention program to enhance self-care and self-efficacy after childbirth.

The purpose of this study was to analyze the factors affecting the awareness of temporomandibular disorders in high school students and to provide basic data for the development of easy-to-access program to help the management of temporomandibular disorders. For data collection, convenience sampling was performed among academic high school students in Daejeon and North Jeolla Province to complete a self-administered questionnaire from December 1 to 30, 2019. The statistical analysis was conducted by t-test, one-way ANOVA, and Pearson correlation. Stepwise multiple regression analysis was conducted. Oral parafunctional habits were positively correlated with trait anxiety and both of them were positively correlated with the perceived symptoms of temporomandibular disorders. The most influential factors on the awareness symptoms of temporomandibular disorders in high school students were oral parafunctional habits, health habits, and trait anxiety. It is necessary to make positive communication and intervention, which meets high school age, in coping well with anxiety and managing oral parafunctional habits and apply an oral health promotion program that involves socio-psychological efforts to prevent them.

The purpose of this study was to typology the integrated care needs of communitydwelling elderly, explore the socio-demographic characteristics of each type, and determine their effects on depression. The secondary data analyses using the 2017 National Survey of the elderly were conducted. The research results are as follows: First, as a result of typology patterns of care needs of the elderly based on the number of chronic diseases, ADL/IADL, dwelling satisfaction, social activities, and social support networks, three clusters were derived; 'low care needs group (LCN), 'high social needs group (HSN)' and 'complex care needs group (CCN)'. Second, compared to HSN, CCN was characterized by older, women, low educational level and urban residence. Third, the level of depression in LCN was lower than that of the HSN, and the depression level of CCN was higher. The practical and policy implications of the results were discussed.
