This study has analyzed the relationship between the oral health status, oral health behavioral status, and obesity targeting 2,110 adults aged 40 years or older who were diagnosed with the cardiovascular disease, and identified the need for a proper weight management and healthy oral care practice for the oral health behavior, with a view to prepare the basic data thereto by analyzing the raw data of the 8th annual raw data for the National Health and Nutrition Examination Survey (2019). As for the oral health behavior of the subjects, the frequency of brushing per day for the obesity group turned out to be the highest at 51.6% (p<0.01), and as for the oral care product other than toothbrush or toothpaste, the use of toothpaste solution turned out to be high at 54.6% (p<0.01). The probability of becoming obese among the obesity group without drinking experiences turned out to be 0.198 times higher than among the obesity group with drinking experiences. Considering the results of this study, there were no significant differences found in terms of the oral health status and oral health behavior status among the patients with cardiovascular disease belonging to the obesity group, yet it was found to be related to the differences according to the lifelong drinking experience. Hence, it is determined that the obesity management among the patients with cardiovascular disease is required via the sys temic and oral health behaviors and appropriate physical activities in daily life.

Objectives : The objective of this study was to estimate a Korean’s lifetime dental expenses depending on diabetics. Methods : We ana lyzed the Korea Health Panel Survey from 2010 to 2017. The samples of diabetics extracted from 137,588 using R version 3.0 in the data of outpatient dental care and estimation of lifetime dental expenditures for diabetics generated using Excel. Results : The results showed that an estimate of average per capita lifetime dental expenditure was about 6.5 million won for men (33 years) and about 6.4 million won for women (30 years). About 50% of their lifetime dental expenditure for diabetics incurred after age 65.

This study was conducted to understand the effect of discussion-type online education on the learning effect of 696 people who took the discussion-type learning at K Cyber University. The collected data were analyzed using ANOVA. As a result of the study, the learning effect increased in all items in 2020 compared to 2019. In the analysis by grade level, there was no significant difference in 2019, but in 2020, the Freshman significantly decreased in learning motivation, interaction and cognitive participation, satisfaction, perceived usefulness, and learn ing achievement. In the analysis by age, in 2019, learning motivation, cognitive participation, perceived usefulness, interaction, and immersion were significantly higher in the age group over 60 years old. In 2020, the motivation for learning was higher in the age group over 60 years old, and in interaction and cognitive participation, under 39 years old and over 60 years old were higher, academic achievement was under 39 years old, and loyalty was under 39 years old and 50-59 years old were higher. As a result, discussion-based learning can be said to be a learning method to improve the learner’s class satisfaction. As a measure to improve learner satisfaction in the future, it is necessary to prepare a basic approach to improve the learning effect for first graders, who have poor learning effects in all items, and to develop various customized learning programs to improve the learning effect by age group.

The purpose of this study was to identify the factors influencing the use rate of nutritional labeling of food by focusing on care food for the elderly. Using the raw data from the 2019 community health survey, 74,547 people aged 65 or older were studied. The relationship between the demographic characteristics, lifestyle habits, masticatory disorders, systemic diseases, and nutrition labeling use rates of food of the study subjects was studied. As the result of the study, it was found that women than men, the lower the age, the higher the education level, two or more households, non-smokers, flexibility exercise, and no mastication disorder, the higher the nutritional labeling use rate, and it did not significantly affect the systemic diseases. Based on the results of this study, it was found that the need for maintaining full-body and oral health was very large in consideration of the characteristics of the elderly. In order to improve the quality of life of the elderly in the future, it is necessary to establish a research and policy support system to improve the awareness of the elderly that nutrition labe

This study has examined the self efficacy, satisfaction of major, and the professionalism of dental hygiene students, and to specify and articulate the factors which influence professionalism, conducted a self entry ques tionnaire survey with 3rd and 4th year students of the dental hygiene department in Seoul and Gyeonggi-do, and used and analyzed the final 184 copies by using the SPSS 21.0 program (IBM SPSS Statistics, New York, USA). The average self efficacy of the research subjects was 3.79, while the average satisfaction of major was 3.88, and the average pro fessionalism was 3.70±0.56. As for the professionalism according to the general characteristics, the 4th year students had 3.84, which was higher than the 3rd year students, and it turned out that the higher the satisfaction of major and satisfaction of practice, the higher the professionalism. As a result of the regression analysis performed to find out the factors influenc ing the professionalism of the research subjects, it turned out that the self efficacy and the satisfaction of major have had a statistically significant effect on the professionalism. Based on the results in the above, it was confirmed that the higher the self efficacy and the satisfaction of major, the more positive the effect on the professionalism. Hence, various educa tional programs would be further needed to improve the dental hygiene and the students’ professionalism, and the continuous education will be required to ensure that the confidence and satisfaction gained via such experiences are led to the positive professionalism.

The purpose of this descriptive study was to compare the health status, attitudes toward robots and demand for human care robots, targeting Korean baby boomers and elderly generations who are end-users of human care robots. Through this study, it was intended to provide basic data for the development of strategies to improve the software technology of the human care robot and increase its utilization. The number of subjects was calculated using the G*Power 3.1.9.2 program. Data were collected from April 23 to May 17, 2019, for a total of 250 people (117 baby boomers and 133 elderly people).

Since the end of the 20th century, the usability of a product has been highly emphasized such that companies in developed countries have established exclusive groups of experts to research usability. In addition, they have spent an enormous amount of funds to avail the differentiated convenience of their own products. The usability of a product means designing a user-friendly product which a consumer can use conveniently, and companies have used the evaluation system for the usability-oriented users in a lab to use the actual products and evaluating the pros and cons of products. Yet, this system requires budgeting for the establishment of experiment and bringing subjects (users) who live in various locations to the lab, and the relevant conditions might result in the usability outcome which the users experienced in their unfamiliar settings. For this study, the so-called AV Player usability evaluation system was showcased in virtual reality in order to solve the problem mentioned above, and also proving that this experiment in virtual reality could result in the same effect as the former experiments which have used the actual products and working mock-up sessions for the purposes of the usability evaluation.

The purpose of this study is to examine and understand the effect of exposure to second-hand smoking at workplace and home on the subjective health condition. Among the causes of death in Korea, the respiratory diseases account for 12.6% of the total, and the risk of smoking, which is a most typical cause of respiratory diseases, has widely been known. Furthermore, smoking causes the second-hand smoking, which has a detrimental effect not only on the smokers but also on the non-smokers around them. Second-hand smoking causes the discomfort due to cigarette smoke as well as health problems including lung cancer and heart disease. Furthermore, negative changes in the subjective health condition cause on to significantly predict the occurrence of health problems, and hence, an analysis was performed to determine the effect of second-hand smoking indoors at workplace and home on the subjective health condition. As a result of the analysis performed, it was confirmed that the subjective health condition was 1.205 times and 1.593 times worse, each respectively, than those who did not have any exposure to the second-hand indoors at workplace and home. Hence, education on the harmful effects of the second-hand smoking on the human body and raising awareness about the tertiary smoking are required at a national level, and the proposal of a specific smoking control policy is proposed.
