This study aimed to suggest the optimum number of rinsing by researching changes in optical density and pH in accordance with the number of rinsing after toothbrushing, and then verifying the amount of residual toothpaste in mouth. Total 14 university students who had healthy body with no difficulties in daily life were selected from the students of K university in Daegu as the research subjects. The research subjects rinsed their mouths with 40ml of water from zero time to 12 times after toothbrushing. After collecting each rinsing water, the optical density and pH were measured. In the results of measuring the optical density value of each rinsing water, the rinsing water of six-seven times or more after toothbrushing showed the constant value of optical density, which was statistically significant(p<0.05). There were no differences in accordance with the amount of toothpaste such as 1g, 1.5g, and 2g. Based on such results of this study, it would be necessary to provide the education of the use of dentifrice, and also to have diverse researches on the effects of residual dentifrice in mouth on the oral cavity.

This study analyzed the effects of labor aging on labor productivity using panel statistics of 16 local governments from 1995 to 2017. The aging of the labor force, defined as the proportion of workers aged 60 or older in total employment, in the results of the panel regression analysis considering regional fixed effects and various adjustment variables, has a very consistent and significant negative effect on labor productivity. For every 1% increase in aging, labor productivity decreases by about 0.14 ~ 0.20%. In addition, the per capita capital stock and human capital considered as adjustment variables contributed to the increase of labor productivity, and the unemployment rate, which is a proxy variable of the economic fluctuation, has a significant negative effect on labor productivity as expected. The coefficient of the industrial structure, which represents the share of the service industry in the whole industry, was positive, but is not significant. The results of this study suggest that the design and construction of economic and educational policies that can maintain and expand human capital are necessary to curb the reduction in labor productivity expected by the aging workforce.

The status of breast cancer screening of women at a breast clinic in a small city in Korea-Using medical records Purpose: This study was conducted to investigate breast cancer incidence by age, including those under 40, and to emphasize the importance of early breast cancer screening for young breast cancer patients. Method: The study was designed as a retrospective survey method. We investigated the medical charts of 483 patients diagnosed with breast cancer among 23,200 visitors to local breast clinic from May 1, 2010 to April 30, 2020. Results: The average age of 483 patients was 47.9, with 36% in their 40s and 28.6% under 40. Among the patients, 5.4% had a family history of breast cancer, and 70.8% were pre-menopausal. The most common reason for visiting the clinic was the mass(54.2%). The size of tumors was less than 2cm (56%), followed by 2-5cm (43.4%) and more than 5cm (5.6%). The size of tumors was smaller in the asymptomatic case than in the symptomatic case. In the pathologic results, invasive ductal cancer was the most common at 80.3%. Conclusions: Breast cancer screening program should be activated even for young women under the age of 40. We suggest educating the importance of breast cancer screening, and lowering the age of national breast cancer screening program.

In this study, the autoregressive cross-lagged model was applied to verify the longitudinal correlation between the three factors and the pattern of changes over time in the mother's cultural adaptation type, the multicultural acceptability of multicultural adolescents, and national identity. For the study, longitudinal data from the 2nd, 4th, 6th, and 8th years of the MAPS tracked from the 5th grade of elementary school to the 2nd grade of high school were used for analysis. As a result of the analysis, all four types of mother's acculturation were analyzed to have a significant longitudinal effect over time. The four types of mothers' cultural adaptation were analyzed to have a longitudinal mediating effect on the relationship between the national identity of multicultural youth. Based on these analysis results, it is necessary to provide a continuous acculturation support program. In order to have a sense of belonging and solidarity with the country, it was suggested that education to increase multicultural receptivity should be carried out in parallel.

Given the rapid development of information and communication technology (ICT) and the deepening of the information gap phenomenon in the context of the COVID-19 pandemic, researchers and practitioners need to understand the changing perceptions of new phenomena such as COVID-19 information gap on the existing information-vulnerable population. In this study, an empirical analysis was performed with the digital information gap survey data in 2020 to understand the potential impact of COVID-19 on the information gap according to the information-vulnerable class. This study is to verify the effect of information gap, marginalized groups, gender, and major factors of information services (contents, social relations, life services, information production, networking, social participation, non-face-to-face services) on the change in perception of digital information technology after Corona. Hierarchical regression analysis was performed. As a result of the analysis, it was found that the higher the content, social relationship, life service, networking, and digital non-face-to-face service, the higher the change in perception of digital information technology after Corona. Therefore, in light of the evolving phenomenon of COVID-19, it is considered that the government needs to provide education and training to strengthen the capabilities of the information-vulnerable class in order to resolve the digital information gap.
