ABSTRACT
How can a smart home system control a connected device to be in a desired state? Recent developments in the Internet of Things (IoT) technology enable people to control various devices with the smart home system rather than physical contact. Furthermore, smart home systems cooperate with voice assistants such as Bixby or Alexa allowing users to control their devices through voice. In this process, a user's query clarifies the target state of the device rather than the actions to perform. Thus, the smart home system needs to plan a sequence of actions to fulfill the user's needs. However, it is challenging to perform action planning because it needs to handle a large-scale state transition graph of a real-world device, and the complex dependence relationships between capabilities. In this work, we propose SmartAid (Smart Home Action Planning in awareness of Dependency), an action planning method for smart home systems. To represent the state transition graph, SmartAid learns models that represent the prerequisite conditions and operations of actions. Then, SmartAid generates an action plan considering the dependencies between capabilities and actions. Extensive experiments demonstrate that SmartAid successfully represents a real-world device based on a state transition log and generates an accurate action sequence for a given query.

PURPOSE: The aim of this study was to determine the effects of nutritional supplements on periodontal health and tooth mobility after surgery. METHODS: Patients were randomly assigned to an intervention group who consumed nutritional supplement drinks for 8 weeks, while the placebo group did not receive any such supplements. The gingival index (GI) and tooth mobility were measured at baseline and at 1, 4, and 8 weeks. In addition, the oral health impact profile-14 and anthropometric measurements along with loss of appetite and dietary intake were assessed at baseline and 8 weeks. RESULTS: At 1 week, GI values were reduced in the intervention group (P<0.05), and tooth mobility had increased, but to a lesser extent in the intervention group (P<0.05). At 8 weeks, the intakes of protein, vitamins A and B1, and niacin were increased in the intervention group. CONCLUSIONS: These results demonstrate that nutritional supplementation improves early periodontal healing after surgery.
ABSTRACT
BACKGROUND: Recently, a revised telehealth legislation that allows direct doctor to patient teleconsultation was proposed in Korea. However, there have been some debates. This study aimed to examine the attitude of primary care physicians towards telehealth. METHODS: A questionnaire asking attitude towards telehealth and revised telehealth legislation was self-administered to 1,988 registered members of Practitioners Council of Korean Academy of Family Medicine. A total of 218 complete responses by family physicians were included in the study. RESULTS: Large proportion (60.6%) of participants disagreed to the main clause of revised telehealth legislation, which allowed doctor to patient teleconsultation. Participants tended to expect that negative outcomes are more likely to occur than positive outcomes after the enforcement of the revised telehealth legislation. Around 50% of participants had an intention to adopt telehealth just as soon (4.6%) or afterwards (45.4%). The majority of participants suggested that; primary care clinic as the most appropriate telehealth facility (75.4%); patients with low accessibility to medical care (74.3%) as the best target of telehealth service; and tele-radiology (61.9%) or tele-pathology (41.3%) as the most applicable medical field for telehealh service. Around 89% of participants suggested telehealth service fee to be similar or higher than current medical consultation fee. CONCLUSION: The majority of family physicians participating in this study were not in favor of the revised telehealth legislation. However, the majority of the participants had an intention to adopt telehealth to their practice and held clear opinion about practical aspects of telehealth.
