PURPOSE. To evaluate adherence of human gingival fibroblasts (HGFs) to transmucosal abutment of dental implant with different surface conditions with time and to investigate the roles of focal adhesion linker proteins (FALPs) involved in HGFs adhesion to abutment surfaces. MATERIALS AND METHODS. Morphologies of cultured HGFs on titanium and ceramic discs with different surface were observed by scanning electron microscopy. Biocompatibility and focal adhesion were evaluated by ultrasonic wave application and cell viability assay. FALPs expression levels were assessed by RT-PCR and western blot. RESULTS. There seemed to be little difference in biocompatibility and adhesion strength of HGFs depending on the surface conditions and materials. In all experimental groups, the number of cells remaining on the disc surface after ultrasonic wave application increased more than 2 times at 3 days after seeding compared to 1-day cultured cells and this continued until 7 days of culture. FALPs expression levels, especially of vinculin and paxillin, also increased in 5-day cultured cells compared to 1-day cultured fibroblasts on the disc surface. CONCLUSION. These results might suggest that the strength of adhesion of fibroblasts to transmucosal abutment surfaces increases with time and it seemed to be related to expressions of FALPs.

The purpose of this study was to investigate biological activities of Brassica rapa (Turnip) plant callus extracts of Ganghwa-gun of Incheon city using water, ultrasonic wave and ethanol extractions to develop functional materials. DPPH radical scavenging activities of the callus extracts were increased in a concentration-dependent manner, as compared with control. The astringent effects of the ethanol extracts were higher, as compared to water and ultrasonic extracts. In the collagen synthesis assay, the ethanol extract showed significant anti-wrinkle effects of 59% and 78% at a concentration of 5 ppm and 10 ppm, respectively. These results suggested that water, ultrasonic wave and ethanol extracts of turnip plant calluses are natural antioxidant sources. Especially, the ethanol extract can be regarded as a functional, natural cosmetic material with astringent and anti-wrinkle effects.

This study was conducted to identify factors related to discomfort while speaking in the elderly and provide fundamental data for establishing oral health care policies for a healthy old age. Using the raw data from the 8th wave of the National Health and Nutrition Examination Survey (2020), we conducted an analysis to examine the relationship between speaking discomfort and mental health, as well as oral health care behavior, among 1,278 elderly individuals in Korea. Differences in speaking discomfort were analyzed based on general characteristics, mental health, and oral health care behavior using complex sample cross-analysis. Additionally, factors associated with speaking discomfort were analyzed using complex sample multiple logistic regression analysis. As a result, individuals with depression experienced higher levels of speaking discomfort (p<0.05), and individuals experiencing high levels of stress also reported higher levels of speaking discomfort (p<0.05). As a factor affecting speaking discomfort, it was found that speaking discomfort was 2.56 times higher (p<0.001) when dental care was not met, and speaking discomfort was 3.05 times higher (p<0.05) when teeth brushing was less frequent. As a result of the aforementioned findings, it is believed that a customized oral health promotion program is necessary to expand dental health insurance coverage for the elderly and improve oral healthcare.

Genre paintings, which describes the lives of ordinary people, has lifestyle and Pungnyu of our ancestors. Pungnyu is aesthetic consciousness and a way of lives. The culture of Pungnyu is a kind of art boundary that combines high spirits and art. The Pungnyu is an icon of Korean culture, realization of taste, and happens through "stroll", which means the walking peacefully, and "sightsee", which means go sightseeing. It shows through the rambling and the excursion. Hyewon's 'Jeonsincheob'('傳神帖', a kind of spirit transferred drawings book) is a genre painting which represents Pungnyu and shows various activities at that time. Therefore, we can understand our own spirit and soul through appreciating his paintings. Hyewon's 「Jeonsincheob」 has three special features. Firstly, it is the symbol of Korea traditional Pungnyu. Secondly, it contributes to development of the East art. Lastly, Hyewon's 「Jeonsincheob」 can be considered in terms of glocalism, which means the combination of globalization and localization and can be explained by the relation of the center=the periphery, the globalization=the Korean wave, the universality=the particularity. Hyewon's 'Jeonsincheob' has aesthetic boundaries. One aims at individual pleasure. Another aims at harmony with its natural environment in which you are. Also, it can be considered as the boundaries of enjoying together which aims at harmony with social environment among group members.

This study aims to explore the positive impact of Korean drama watching satisfaction on purchase intention for Korean products by considering the mediating roles of social distance to Korea, national image of Korea, and Korean product image. This study identified that Korean drama reduced the social distance to Korea while increasing the positive image of Koreas and Korean products. However, the reduced social distance was not positively associated with Korean product image and Korean product purchase intention. This implies that Korean dramas directly affect Korean product purchase intension and indirectly affect Korean national image and product image. This study supplies guidance to international marketers who aims to enter the Myanmar market. To use the Korean wave as a Korean product marketing tool, marketing strategies need to cover Korean culture-relevant materials such as cultural background, cultural characteristics, exposed products, and so on.

Recently, the Korean wave has caused many foreign nations to pay attention to various fields including Korean culture, arts, fashion and beauty. Korean images so far were mainly discussed in terms of aesthetics, and there is lack of efforts to visually shape Korean images. On the contrary, Oriental images focused around Japan and China have greater global influence and better globalized fashion styles compared to Korea. Therefore, it is necessary to suggest a globalized proposal of Korean fashion styling which reflects original and unique aesthetic characteristics of Korea that can be accepted by the global market. In this study, the concept and types of fashion styling and stylists were examined, as well as the definition of Korean image and types and characteristics of Korean images shown on fashion magazines. Also, after collecting photographs having Korean images that were included in the editorial fashion styling of Vogue Korea, their characteristics were analyzed. The results of interviews with professional fashion stylists were summarized to propose an editorial fashion styling with Korean image for overseas consumers who long for and wish to imitate Korean fashion styling.
