Objectives : The objective of this study was to investigate the relationship between the status and necessity of dental prosthesis and mastication function in the Korean elderly. Methods : This study investigated 4,557 elderly people aged over 65 in the 5th Korea National Health and Nutrition Examination Survey(2010-2012). Frequency analysis, ${\chi}^2$ test, and logistic regression analysis were used. Results : Those aged over 75 complained of greater discomfort in mastication function than those from 65 to 74, and it was statistically significant(p<0.001). Mastication discomfort was not so significant in those with higher education and higher income(p<0.001). Those who did not use prosthesis tended to have better mastication function(p<0.001). Denture users complained of mastication discomfort when they used it(p<0.001). Conclusions : This study verified the relationship between the discomfort in mastication and related factors, and will provide the basic data for the access to dental clinic services.

Background: Whether the use of electronic cigarettes (ECs) is associated with upper airway diseases, including chronic rhinosinusitis (CRS) and allergic rhinitis (AR), remains unclear. Methods: We analyzed data from the nationwide cross-sectional surveys: the Korea National Health and Nutrition Examination Survey VI (2013-2015), VII (2016-2018), and VIII (2019). Logistic regression analysis was performed to assess the association between EC use and CRS or AR. Results: Among a total of 38,413 participants, 6.4% were former EC users and 2.5% were current EC users. Former EC users and current EC showed a significantly increased OR for CRS or AR compared with never EC users. In the subgroup analysis, the "current CC (conventional cigarette)-current EC" and the "current CC-formal EC" group had a significantly higher OR for CRS or AR than the "current CC-never EC" group. In addition, former CC smokers who currently use ECs showed a significantly higher OR for AR than former CC smokers without EC use. Conclusions: EC use is significantly associated with a high prevalence of CRS and AR in the adult population. These results indicate that the use of ECs may increase the risk of upper airway disease.

Since 2013, adults aged over 20 can receive national health insurance scaling once a year in South Korea. In this study, we analyzed the usage status of national health insurance care service for periodontal disease in 2010-2018 by using Healthcare big data of the Health Insurance Review and Assessment Service. The increase rate of the dental care users was very high at 7.8 and 11.2% in 2013 and 2014, respectively. These are higher than the increase rate of all medical institution users, which is between -1.7 and 3.7%. In 2017, the rate of dental use was 44.4%, which has increased more than 10% compared to 2012. Percent receiver of national health insurance scaling was 19.5% in 2017. The 20s had the highest rate of 23.2%. The rate decreased with age. Based on these results, it can be evaluated that the expansion of national health insurance coverage for scaling improves accessibility to dental care. A more long-term assessment of the effect of periodic dental examination and scaling on reducing the prevalence of periodontal disease is needed. National health insurance coverage should be extended to oral hygiene education and supportive periodontal therapy in order to prevent periodontal disease.

Coronary heart disease (CHD) is a comorbidity of COVID-19; therefore, routine early diagnosis is crucial. A large number of examination attributes in the context of diagnosing CHD is a distinct obstacle during the pandemic when the number of health service users is significant. The development of a precise machine learning model for diagnosis with a minimum number of examination attributes can allow examinations and healthcare actions to be undertaken quickly. This study proposes a CHD diagnosis model based on feature selection, data balancing, and ensemble-based classification methods. In the feature selection stage, a hybrid SVM-GA combined with fast correlation-based filter (FCBF) is used. The proposed system achieved an accuracy of 94.60% and area under the curve (AUC) of 97.5% when tested on the z-Alizadeh Sani dataset and used only 8 of 54 inspection attributes. In terms of performance, the proposed model can be placed in the very good category.

Smart healthcare, combining ICT (Information and Communications Technologies) and medical technologies, has been rapidly emerging. Accordingly, its market has also increased as interest in disease prevention, management, and diagnosis grows due to the COVID-19 pandemic. In particular, using mobile devices to support medical activities, mobile healthcare has been attracting attention as a leading service in the smart healthcare market. However, the intention to use mobile healthcare apps may vary depending on individual beliefs and attitudes. Many studies on the intention to use mobile healthcare apps have used the TAM (Technology Acceptance Model), but there is a lack of studies that have been verified from the perspective of users' health beliefs. This study aims to identify the factors that affect the intention to use mobile healthcare apps based on the HBM (Health Belief Model). Furthermore, it investigates how this influencing mechanism fluctuates based on the user's mHealth literacy, the ability to find and understand health information through mobile. This study contributes to the empirical examination of the intention to use mobile healthcare apps through the HBM. It also offers insights for app providers and public health officials to increase the use of mobile healthcare apps.

Objectives: This study aims to investigate the elements to affect the usage of individual oral hygiene devices in adults by the age group, to make the community inhabitants keep their healthy dental hygiene status, and to provide them with the educational materials for the dental hygiene and the basic data for the program development. The purpose of the study is to investigate the relation ot use of oral hygiene devices in the adults. Methods: The subjects were 9,073 adults from the sixth KNHANES from January, 2013 to December, 2014. The study consisted of questionnaire survey and direct physical examination. The questionnaire included genral characteristics of the subjects and oral health characteristics. The general characteristics consisted of subjective perception of health and chronic diseases. The oral health characteristics consisted of subjective oral health perception, dental caries, periodontal disease, annual oral examination, toothbrushing, prosthetics, implant surgery, and use of individual oral hygiene devices. Results: Those within 40 to 64 years old were the top users of oral hygiene devices. They perceived their dental hygiene was normal because they did not have periodontal disease but most of them had dental caries. They used oral hygiene devices three times a day and brushed teeth more than three times a day. They took annual dental checkup. Conclusions: It is necessary to promote the use of oral hygiene devices to prevent the dental caries and periodontal disease. The continuous training for the dental hygienists is very important because the dental hygienists is the first line of the prevention of dental caries and periodontal disease.

Cloud computing is an internet-based technology, providing services to the virtualized IT environment, and allowing users to add or remove resources of hardware or software at their discretion. Since Cloud computing can construct virtually integrated environments out of multiple local computing environments, various information services can be provided by it. In addition, state organizations also strive to build the cloud computing environments due to the benefits of reduced costs to introduce the system and of reduced time to build and provide the IT services. This study suggests a web-based cloud computing system for the computing environments, to be applied for the Korean National Health and Nutrition Examination Survey (KNHANES) by the Ministry of Health and Welfare, Republic of Korea.

Aspects of health food intake were investigated by conducting a questionnaire survey with over 480 of adults in Taejon and the data were analyzed by $\chi$$^2$-test, t-test and ANOVA, using an SAS program. Eighty two percent of the subjects had taken some kind of health food. The health foods they took frequently were, for example, health drinks, green tea, ginseng products, dietary fiber drinks, honey, general tea, vitamin B, vitamin C, and tonic medicines. The main reason for taking health foods was recovery from fatigue and the frequency of taking health foods was one time per day. Most of the subjects took health foods without knowledge of their components or effects. When they health foods with a perceived knowledge of their components and effects, they responded that the health foods were very helpful for them. Twenty percent of subjects experienced side effects, such as diarrhea, stomachache, headache, nettle rash, and stomach cramps. Information on health foods was obtained mainly from friends or family. The user group showed higher intention to continue health food intake than non users(p < 0.001). Health foods were taken without any knowledge about them. Health food intake was significantly correlated with consideration of disease, suffering or disease, medical examination, and self-perceived health status, but not with food habits and health food knowledge. As for the results from the adults consumption pattern of health food, an education program should be developed to choose proper health foods according to the consumers dietary life and health conditions. Also a proper guide line should be established to be chosen the authorized health foods.
