Objectives: This study aimed to identify the level of digital oral health literacy among Korean adults in Gangwon-do. Methods: A survey was conducted through face-to-face interviews with adults aged 30-89 residing in Gangwon-do, South Korea. The independent variables were socio-demographic characteristics, including gender, age, education level, income, and occupation. The dependent variable was digital oral health literacy. The statistical analysis included Independent t-test, one-way ANOVA, Pearson correlation analysis, and multiple linear regression analysis, all performed using the SPSS 27.0 software program. Results: The elderly and those with poor socioeconomic status (p<0.001) had lower average scores due to poor digital oral health literacy. The ease of searching for oral health information and the utilization of digital devices to search for information on oral health displayed a significant relationship (r=0.730, p<0.001). To develop the use of digital devices, simplifying the search for oral information (p<0.001) is essential. Conclusions: All socio-demographic characteristics, except gender, displayed a correlation with the level of digital oral health literacy. Both environmental and individual aspects of the respondents' living conditions must be considered to improve digital oral health literacy.

Recently, with various developments made to smart-phones and other digital devices in the IoT environment, modern people tend to pursue comfort in their own lifestyles. These environment has helped us to obtain any information or data in despite of location and time. But it has caused them to be overly reliant on digital devices in doing any kind of daily work, trusting the digital devices more than oneself. As a result of this over reliance, modern people's memorizing and calculating ability have deteriorated critically. This symptom is known as the Digital Dementia. In this paper, we study the phenomenon of digital dementia caused by smart-phones, and we suggest a method of developing "memorize the phone number" game applications in IoT environment to the problem of digital dementia. Test results show that, through the use of application, not only the users were able to have fun memorizing the numbers, but also, to show improvement in their memorizing ability. Thus, we expect that the application suggested above will help in preventing digital dementia and maintain brain health.

PURPOSE. The maximum width between the mesial and distal labial transitional line angles, described as "esthetic width" herein, could significantly influence the visual perception of the teeth and smile. This study aimed to conduct biometric research on esthetic width and to explore whether regular distribution exists in the esthetic width of human teeth. MATERIALS AND METHODS. A total of 4,264 maxillary and mandibular anterior teeth were measured using the Geomagic studio software program. The proportions of maxillary to mandibular homonymous teeth and proportions between the adjacent teeth were calculated. Bilateral symmetry and the correlation between the esthetic and mesiodistal widths were both accounted for during the measurement procedures. RESULTS. The mean esthetic widths were 6.773 ± 0.518 mm and 4.329 ± 0.331 mm for maxillary and mandibular central incisors, respectively, 5.451 ± 0.487 mm and 5.008 ± 0.351 mm for maxillary and mandibular lateral incisors, respectively, and 3.340 ± 0.353 mm and 5.958 ± 0.415 mm for maxillary and mandibular canines, respectively. Except for the mandibular canines, no significant difference in esthetic width was found among homonymous teeth from the same jaw. A high linear correlation was found between the esthetic and mesiodistal widths of the same tooth, except for the maxillary canines. Esthetic width proportions among different tooth categories showed some regular patterns, which were similar to those of the mesiodistal width. CONCLUSION. Esthetic width is regularly distributed among the teeth in the Chinese population. This could provide an important reference for anterior dental restorations and dimension recovery in esthetic reconstruction of anterior teeth.

본 연구는 중고령자의 디지털헬스기기에 대한 자기효능감과 이용의도 간의 관계를 중장년층과 노년층 집단별로 살펴보고자 하였다. 이에 따라 본 연구는 『2019 한국 중·고령자 기술수용도 조사』를 이용하여, 빈도분석과 T-test 분석, 선형회귀분석을 시행하였다. 본 연구의 분석결과는 다음과 같다. 첫째, 중장년층과 노년층의 디지털헬스기기 이용의도를 비교한 결과, 중장년층의 이용의도(5.07점)는 노년층(4.86점)에 비해 상당히 높은 것으로 나타났다. 둘째, 중장년층의 자기효능감(7.74점) 역시 노년층(6.21점)보다 높게 나타났지만 두 연령집단 모두 절반보다 높게 나타나 상당히 높은 자기효능감을 갖고 있는 것으로 나타났다. 마지막으로, 연령집단별 자기효능감과 이용의도 간 관계를 살펴본 결과, 중장년층의 경우 자기효능감과 이용의도 간의 관계가 유의미하지 않은 것으로 나타났으나 노년층의 경우에는 자기효능감과 이용의도 간의 관계가 정적인 방향으로 영향을 미치는 것으로 나타났다. 즉, 노년층의 경우에는 디지털기기에 대한 자기효능감이 높을수록 디지털헬스기기 이용의도가 높아지는 것으로 나타났다. 이와 같은 연구결과를 통해 중고령자의 디지털헬스기기 활용 증진을 위해서는 자기효능감을 증진시킬 수 있는 교육프로그램이 선제적으로 도입될 필요가 있으며, 중장년층과 노년층의 연령집단 특성에 따라 차별화된 전략이 필요함을 제시하였다. 본 연구는 연령집단에 따른 디지털헬스기기 이용의도 연구의 기초연구가 될 것으로 기대하며 후속연구로서 유용성, 편의성, 불안 등이 포함된 연구를 제시하였다.

Smart devices refer to various devices and control equipment such as health care devices, imaging devices, motor devices and wearable devices that use wireless network communication (e.g., Wi-fi, Bluetooth, LTE). Commercial services using such devices are found in a wide range of fields, including home networks, health care and medical services, entertainment and toys. Studies on smart devices have also been actively undertaken by academia and industry alike, as the penetration rate of smartphones grew and the technological progress made with the fourth industrial revolution bring about great convenience for users. While services offered through smart devices come with convenience, there is also various security threats that can lead to financial loss or even a loss of life in the case of terrorist attacks. As attacks that are committed through smart devices tend to pick up where attacks based on wireless internet left off, more research is needed on related security topics. As such, this paper seeks to design an access control method for reinforced security for smart devices. After registering and authenticating the smart device from the user's smart phone and service provider, a safe communication protocol is designed. Then to secure the integrity and confidentiality of the communication data, a management process such as for device renewal or cancellation is designed. Safety and security of the existing systems against attacks are also evaluated. In doing so, an improved efficiency by approximately 44% compared to the encryption processing speed of the existing system was verified.
