The purpose of this study was to investigate the effects of smoking on adult periodontitis after non-surgical periodontal therapy. The study population consisted of 40 patients with moderate to advanced periodontitis. Smokers(n=20) were defined as individuals smoking at least twenty cigarettes per day at the time of the initial examination. The non-smoking group(n=20) second and the fourth weeks after periodontal non-surgical therapy. The results were as follows; 1. Clinical indices including plaque index, gingival index, and pocket depth were decreased in both smoking and non-smoking group at the first, the second, and the fourth weeks. Especially, clinical indices of non-smokers were more significantly decreased than those of smokers. 2. Non-motile rods were increaseed and motile rods were reduced at the fourth week. spirochetes were reduced significantly in the non-smoking group at the fourth week. These results suggest that smoking play a minor role in adult periodontitis after non-surgical periodontal therapy.

The study population consisted of 40 patients with moderate to advanced periodontitis. Smokers (n=20) were defined as individuals smoking at least twenty cigarettes per day at the time of the initial examination. The non-smoking group (n=20) consisted of individuals who were not smoking at the initial examination. The average age was 42.4 years for the smoking and non-smoking group. Examination regarding plaque index, gingival index, pocket depth and contrast phase microscope were performed. Evaluation were made at the first, the second and the fourth weeks after periodontal non-surgical therapy. The results were as follows: 1. Clinical indices including plaque index, gingival index, and pocket depth were decreased in both smoking and non-smoking group at the first, the second, and the fourth weeks.

Gingival fibroblasts are major cellular component of gingiva. However, the molecular mechanisms of senescence of human gingival fibroblasts are unknown. Human fibroblasts undergo replicative senescence in vitro after a limited number of population doublings. A reduced rate of proliferation is a prominent phenomenon observed in senescent fibroblasts. This phenomenon is controled by cell cycle regulatory proteins. The purpose of present study was to investigate the effect of replicative senescence on cell cycle progression and to find out its molecular mechanisms in human gingival fibroblasts. Replicative senescence of gingival fibroblasts were induced by subsequent cultures that were repeated up to 18 passage. In the present study, I examined change of cell proliferation, cell activity, cell viability and cell cycle progression during the replicative process. Also, I examined expression of cell cycle regulatory proteins which was estimated by western blot analysis. Cell proliferation, cell activity and cell viability of gingival fibroblasts were notably decreased with increase of population doubling level(PDL). S phase was decreased and G1 phase was increased with increase of PDL. Western blot analysis showed that levels of P16, p21 and p53 of senescent gingival fibroblasts(PDL41, PDL58) were higher than young fibroblasts(PDL27) and cdk4 were lower than young fibroblasts(PDL27). In conclusion, these results suggest that proliferative function of human gingival fibroblasts may be decreased by replicative senescence and its molecular mechanisms may be activatied with p16, p21, p53 and pRB, and repressed wtih cdk4.

(Background and Purpose) Space branding is the most effective way for modern companies to communicate their brands and identities to customers. As purchasing shifts from offline to online, space branding has become important in providing customers with experiences and creating brand experiences in offline spaces. However, problems have arisen, such as the failure to establish a brand image owing to excessive and simplistic trends and sensibilities. Therefore, this study aimed to identify the most appropriate space for a brand from the perspective of space branding by analyzing previous research related to space branding, establishing evaluation indicators, and conducting case studies. (Method) Based on previous research and literature reviews on the concept of space branding, the components and characteristics of the concept were derived. Second, the evaluation criteria were organized, and relationships were established by connecting keywords related to the concept. Third, four locations were selected as case study examples, and an analysis was conducted based on the derived components. Fourth, a Pugh Concept Test evaluation was conducted, and calculations were made based on the criteria applied to each case. (Results) As a result of the case analysis with the components derived through the previous study analysis, Gentle Monster had the highest score. Gentle Monster has accumulated a leading brand image by transforming its perception from "glasses" to "eyewear" through space branding. The Apple Store immediately delivers the brand image to the user with a consistent space branding element, resulting in simplicity. Starbucks did space branding by turning the brand itself into a "product" as a "third space" rather than a space for selling coffee. Finally, Hyundae Card succeeded in transforming its image from the “financial industry” to “sophisticated” through space branding. (Conclusions) This study investigated spaces that increase the value of a company through space branding. The results showed that, first, the type of consumption has changed from offline to online, drawing more attention to offline experiences and brand value delivery. Second, the keywords derived through the literature search can be summarized into four categories: leadership, simplicity, topicality, and unexpectedness. Third, Gentle Monster was the most successful case of space branding based on the case studies and evaluation indicators; however, it showed insufficient scores for simplicity. Fourth, companies believe that by planning spaces that encapsulate the image and value of their brands, they can directly imprint their brands on consumers. This study proposed evaluation indicators that can be used in future space branding. Furthermore, space branding can be applied not only to commercial spaces for profit, but also to public facilities and spaces for the public’s benefit.

공공도서관과 학교도서관의 협력 활동을 극대화할 수 있는 방안을 도출하기 위하여 협력의 필요성과 이론적 연구, 도서관 협력현황과 문제점, 도서관 협력에 대한 사례와 문제점을 분석하여 우리나라 현실에 적용할 수 있는 바람직한 협력 방안을 제시하고자 하였다. 우리나라 도서관 수준이 선진국과 비교하여 매우 열악한 현실은 부인할 수 없지만 최근 일련의 정부정책과 도서관계의 꾸준한 노력으로 그 미래는 밝을 것으로 평가된다. 이러한 시점에서 근본적인 문제 해결과 도서관 협력 및 전반적인 활성화를 위하여 제반 여건 조성과 지원이 필요하다.

스페이스 브랜딩의 도시 공공문화공간에 대한 연구

박영채,김주연,장영호 한국공간디자인학회 2023 한국공간디자인학회논문집 Vol.18 No.3

(Background and Purpose) Public spaces are an element that comprise urban forms and are the most basic way to form urban culture, including both public and private spaces. With rapid social change, the importance of public spaces in which people can enjoy a cultural life is also increasing. However, public spaces that have achieved quantitative growth gradually lose their function and meaning and fail to attract user interest, showing insufficient performance in terms of activation. To revitalize public spaces and improve the lives of city residents, a modern value-oriented approach is needed. The purpose of this study was to focus on the use of space branding and the intersection of space branding and public spaces as a tool to increase the value and utility of public spaces, because they have only been developed in terms of physical elements. (Method) This study aimed to analyze the characteristics of public cultural spaces through the branding of urban public cultural spaces. The spatial scope was limited to cultural spaces with the highest utilization of space branding. First, through theoretical considerations, we identified the meanings of space branding, public spaces, and public cultural spaces. Second, we reconstructed the elements from the extracted keywords. Third, we selected domestic cases of space branding in urban public spaces and formed the evaluation items and contents. Fourth, we performed the evaluation and analysis of all case studies. (Results) As a result of conducting case studies, "Seoul Art-Checkbogo,” an art book-based public cultural space in Korea, was found to have the highest comfortableness, informativeness, and publicity, but it was insufficient in terms of general design. The "Oil Tank Cultural Park" was recreated as a cultural and artistic space on the site of an old oil tank, and showed high accessibility, informativeness, placeness, and publicity, but as it is an old building, its comfortableness and visuality were low. “Jungrimchanggo” is a harmonious cultural space located in the old city center that can be seen as an example of space branding applied to a space with high visuality, experience, placeness, publicity, and relationships. (Conclusions) With the increasing importance of urban public spaces, space branding has been conducted to enhance the value and competitiveness of public cultural spaces and revitalize them. The results of this study were as follows: First, most public cultural spaces exhibited physical openness, with publicity appearing to be the most important. Second, public cultural spaces should focus on relationships, visuality, and experience rather than on accessibility to local residents' cultural and artistic activities. Third, space branding should be applied not only to commercial spaces, but also to the revitalization and competitiveness of public spaces, which will play a role in creating and activating positive perceptions of public spaces.

A Study on the Need for Untact Communities for the Depressed Elderly in a Post-Aged Society

박영채,김주연 한국공간디자인학회 2022 한국공간디자인학회논문집 Vol.17 No.2

(Background and Purpose) According to the National Statistical Office, Korea expects the number of people aged 65 or older to increase rapidly to 16.5% in 2021, 20.3% in 2025, and 43.9% in 2060. The life expectancy of domestic survivors is 1.8 years higher for women and 0.8 years for men than the average 65-year-old survivor of the OECD, so the relatively fast entry into a super-aged society entails various problems. As we enter a super-aged society, depression among the elderly is increasing due to complex problems such as economic activity, social activity, and the absence of care providers. Therefore, the purpose of this paper is to inform the practical situation of entering a super-aged society and the need for a depression-free community for the elderly, whose depression has rapidly increased due to sudden COVID-19. (Method) This study focuses on elderly people who are alienated due to overlapping COVID-19 situations in a super-aged society and are depressed due to economic difficulties or social activities, and elderly people who are unable to go out or engage in external community activities due to COVID-19. First, after examining the aging and aging depression through literature research, then examine how the global paradigm has changed due to COVID-19. Second, a current status survey is conducted on Seongnam-si to find out the changes in the lives of the elderly after the outbreak of COVID-19. Third, it examines domestic and foreign untact communities and derives and analyzes the reasons and limitations of cases that need to be switched from face-to-face. (Results) Through this study, the necessity for the depressed elderly in the rapidly aging society is as follows. First, as the face-to-face community, which was possible due to social distancing due to Corona 19, became impossible, the elderly were only able to sit on the street. Through this, analysis can check various types of types. Second, various untact communities are provided to the depressed elderly due to social disconnection, but there seems to be an urgent need for untact human interaction rather than unilateral use and experience. (Conclusions) Based on the research conducted by the face-to-face community for the better life of the elderly in need due to physical problems and COVID-19, it is hoped that support such as digital device distribution and education will be activated nationwide in the future, and many studies will be conducted.
