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.

Conventional nutrition services involve producer-oriented approaches without considering the differences in the characteristics and circumstances of each individual, whereas personalized nutrition services are consumer-oriented concepts that provide products and services for maintaining optimal health conditions based on the genetic, physiological, and metabolic characteristics of individuals, with these products based on balanced nutrition and healthy living. Currently, methods for evaluating dietary habits, monitoring dietary behaviors, deep phenotyping, and metabotyping via microbiota profiling, as well as methods for predicting big data by using machine learning, have been previously studied in Korea and abroad. With the development of medical technology and the improvement of hygiene, the demand for personalized nutrition and health services for healthier, happier, and more satisfying lives is rapidly increasing. Therefore, based on scientific technologies, attempts are needed to advance these services into global personalized markets and to boost the global competitiveness of countries and companies.

최근 의료계에서 환자가 의료서비스의 소극적인 객체가 아니라 주체로서 인식되면서 환자의 위상을 강화하기 위한 다양한 시도가 이뤄지고 있다. 지금까지 의사가 주도했던 의료커뮤니케이션이 소비자주권의식과 의료정보의 활성화로 점차 환자중심으로 이동하고 있다. 이 글에서는 IT의 발달로 의료정보가 대중화되면서 환자들이 환우회, 소비자운동 등을 통해 의료소비자로서 위상을 강화하는 과정을 살펴본다. 이를 위해 의사와 환자의 커뮤니케이션에 영향을 미치는 의료정보의 역할, 환자 커뮤니티의 소비자운동 등을 다루고자 한다. 또한 정보통신기술을 활용한 의료시스템이 뿌리를 내리기 위해 연결망을 형성하고 실패하는 과정을 ANT(행위자-연결망이론)를 통해 분석한다. 환자중심의 의료서비스는 IT기술을 이용한 다양한 헬스케어 서비스 시장을 창출하며 의료정보의 비대칭성 개선에 기여하고 있다. IT융합 헬스케어 시장의 확대는 의사와 환자의 전통적인 관계에 근본적인 변화를 가져오면서 의료서비스시장을 재편하고 있다. 환자가 주도하는 모바일 헬스케어 모델의 확산 등 환자중심 의료가 가속화되고 있는 것이다.

Objective: Combined oral contraceptives (COCs) have some adverse effects on the serum lipid profile. Because hyperlipidemia is one of the risk factors in cardiovascular diseases, lipid abnormalities should be evaluated in women consuming COCs. Vitamins E and C are known to have beneficial effects on serum lipid profiles. Therefore, in this study, we evaluated the effects of vitamins E and C on serum lipids in women using COCs. Methods: The study compared changes in lipid parameters with and without vitamin therapy in women consuming COCs compared to those of a control group (40 non-contraceptive users or NCU) for 4 weeks. Total cholesterol and triglyceride, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels along with HDL/LDL ratios were measured for all participants. Results: COC users experienced significantly higher increases in the levels of triglycerides and LDL than non-users (p<0.05). However, no significant differences were noted in the total cholesterol and HDL levels. In the treated COC group receiving vitamins E and C, the HDL level and the HDL/LDL ratio increased and the LDL and triglycerides levels decreased significantly compared with those of the other groups. Conclusion: The results of our study indicate that supplementation with antioxidant vitamins E and C restores a normal lipid profile in COC users.

Objectives. Two main digital signal processing technologies inside the modern hearing aid to provide the best conditions for hearing aid users are directionality (DIR) and digital noise reduction (DNR) algorithms. There are various possible settings for these algorithms. The present study evaluates the effects of various DIR and DNR conditions (both separately and in combination) on listening comfort among hearing aid users. Methods. In 18 participants who received hearing aid fitting services from the Rehabilitation School of Shahid Beheshti University of Medical Sciences regularly, we applied acceptable noise level (ANL) as our subjective measure of listening comfort. We evaluated both of these under six different hearing aid conditions: omnidirectional-baseline, omnidirectional-broadband DNR, omnidirectional-multichannel DNR, directional, directional-broadband DNR, and directional-multichannel DNR. Results. The ANL results ranged from -3 dB to 14 dB in all conditions. The results show, among all conditions, both the omnidirectional-baseline condition and the omnidirectional-broadband DNR condition are the worst conditions for listening in noise. The DIR always reduces the amount of noise that patients received during testing. The DNR algorithm does not improve listening in noise significantly when compared with the DIR algorithms. Although both DNR and DIR algorithms yielded a lower ANL, the DIR algorithm was more effective than the DNR. Conclusion. The DIR and DNR technologies provide listening comfort in the presence of noise. Thus, user benefit depends on how the digital signal processing settings inside the hearing aid are adjusted.

The advances in electronic medical records (EMRs) and bioinformatics (BI) represent two significant trends in healthcare. The widespread adoption of EMR systems and the completion of the Human Genome Project developed the technologies for data acquisition, analysis, and visualization in two different domains. The massive amount of data from both clinical and biology domains is expected to provide personalized, preventive, and predictive healthcare services in the near future. The integrated use of EMR and BI data needs to consider four key informatics areas: data modeling, analytics, standardization, and privacy. Bioclinical data warehouses integrating heterogeneous patient-related clinical or omics data should be considered. The representative standardization effort by the Clinical Bioinformatics Ontology (CBO) aims to provide uniquely identified concepts to include molecular pathology terminologies. Since individual genome data are easily used to predict current and future health status, different safeguards to ensure confidentiality should be considered. In this paper, we focused on the informatics aspects of integrating the EMR community and BI community by identifying opportunities, challenges, and approaches to provide the best possible care service for our patients and the population.
