This study was pursued for the sake of gathering fundamental information to implement school-based comprehensive oral health care program and for planning oral health care program in consideration of parents. The following results were obtained by investigation of consciousness and favor level of 215 parents, who have elementary school children, regarding school-based comprehensive oral health care program. 1. It appears that many parents are not knowledgeable about school-based comprehensive oral health care program. There were significant differences between recognition level of school-based comprehensive oral health care program and age(PE0.05). 2. The parents acquired information about school-based comprehensive oral health care program; 58.7% by their children, 11.2% by mass-media, 10.0% by dentists and 3.7% by dental hygienists. 3. Most parents are in favor of school-based comprehensive oral health care program (96.7%). 4. Many parents(63.7%) prefer that social security law should budget for oral health care program. There were significant differences by sex(PE0.05) and age(PE0.01) As most parents are not so conscious of school-based comprehensive oral health care program, appropriate education program for dentists, dental hygienists and parents should be developed urgently.

Internet of Things (IoT) is the paradigm of network of Internet-connected things as objects that constantly sense the physical world and share the data for further processing. At the core of IoT lies the early technology of radio frequency identification (RFID), which provides accurate location tracking of real-world objects. With its small size and convenience, RFID tags can be attached to everyday items such as books, clothes, furniture and the like as well as to animals, plants, and even humans. This phenomenon is the beginning of new applications and services for the industry and consumer market. IoT is regarded as a fourth industrial revolution because of its massive coverage of services around the world from smart homes to artificial intelligence-enabled smart driving cars, Internet-enabled medical equipment, etc. It is estimated that there will be several dozens of billions of IoT devices ready and operating until 2020 around the world. Despite the growing statistics, however, IoT has security vulnerabilities that must be addressed appropriately to avoid causing damage in the future. As such, we mention some fields of study as a future topic at the end of the survey. Consequently, in this comprehensive survey of IoT, we will cover the architecture of IoT with various layered models, security characteristics, potential applications, and related supporting technologies of IoT such as 5G, MEC, cloud, WSN, etc., including the economic perspective of IoT and its future directions.
