This paper is composed of a passenger management system using a temperature sensing module, a PIR sensor module for detecting movement inside a room, and a smart breath sensing module for determining a sleeping state. An embedded sensor module and a communication system integrated the sensing part and the algorithm driving part. As the aging society is accelerating and becoming more upgraded, the social cost of Silver Care increases, and in order to protect privacy, it is necessary to reduce costs by developing efficient smart silver care devices. The proposed non - image human body detection IOT sensor system is implemented by hardware and software and has superior performance compared with conventional image monitoring method.

Recent advances in healthcare-adapted devices, the increase in chronic diseases and the increasing social needs due to aging, trigger the development of smart healthcare systems and present a new medical paradigm. As a result, moves are being made to accommodate the changing healthcare concept of modern residential areas. In particular, the bathrooms in residential areas are becoming diverse as medical spaces with various types of bathroom culture. Therefore, by actively utilizing the digital medical procedure 3, the smart health care system was applied, I thought about future bathroom products (like smart shower and smart scales) and searched for the technology necessary for each person's needs. By planning a product suitable for a changing bathroom, it will be useful for the development of smart healthcare technology through future national and policy improvements in preparation for the age of the fourth industrial revolution.

Recently the study about a smart health care which is combined IT with BT to provide a variety of health care services are being actively investigated. In order to provide the best possible emergency medical services in a short period of time, it is necessary that the rapid emergency measures in the event of an emergency essential. In this paper, we propose an emergency medical service platform to take effective first aid to person who has a NFC tag or NFC-enabled mobile smart phones in an accident. Using NFC, it is possible to help without physical contact to the patient unconscious to emergency incidents such as falling down in everyday life. In this paper, we design and implement an mobile emergency medical system that can deliver first aid information ask for help in case of emergency.

This paper proposes a smart glass-based emergency tele-medical direction system. This system is designed for hospital specialists to provide remote medical guidance to on-site coast guards or emergency responders. To identify the requirements necessary for system development, relevant technological trends and case studies were analyzed. Based on this analysis, three system requirements were defined: 1) The system must be able to determine the necessity of patient transport, 2) It should assist in providing emergency medical care during transport to the hospital, and 3) It must be capable of transmitting patient information to medical facilities. A prototype that meets these requirements was developed and its usability was evaluated.

In this paper, we introduce the results of the development of a care robot for the safe lifting and transportation of bedridden patients with difficulty moving by themselves, especially, in medical facilities. The purpose of the developed patient transfer robot is to improve the convenience of care givers and enhance the safety and comfort of care recipients by facilitating patient lifting and patient transfer tasks by applying robot technology. In order to implement the lifting function, a hoist was designed and developed, and a sway control and rollover warning system were included in the hoist module as product differentiators. In addition, in terms of implementing the transfer function, an omnidirectional movement mechanism to improve operability in confined spaces and an active safety system to prevent collisions were developed. The function of the developed patient transfer robot was verified through performance evaluation by an authorized testing agency.

This study's purpose was to analyze the effect of the SmartCare obesity management pilot project, which was conducted between 09 March 2011 and 03 April 2013 in Korea (South). Of 212 subjects who were enrolled in the study, the final analysis was conducted with 147 subjects who completed their weight self-measurements and SmartCare services until the end of a 6-month service period. The self-measurement group for evaluation was classified into 3 groups (Low, Middle, and High) by evenly dividing the monthly average frequency of measurement for 6 months and the evaluation indices were weight, and BMI (Body Mass Index) transmitted from the SmartCare System. The monthly average weight and BMI were decreased more in the High Group than the Middle Group and Low Group (M5: High>Middle>Low), and they are showing statistically significant differences between groups (p< 0.05). In conclusion, analysis of the weight and BMI improvement effect showed a greater improvement effect when the self-measurement frequency level was higher.

Columnar-structured cesium iodide (CsI) scintillators doped with thallium (Tl) are frequently used as x-ray converters in medical and industrial imaging. In this study we investigated the imaging characteristics of CsI:Tl films with various reflective layers-aluminum (Al), chromium (Cr), and titanium dioxide ($TiO_2$) powder-coated on glass substrates. We used two effusion-cell sources in a thermal evaporator system to fabricate CsI:Tl films on substrates. The scintillators were observed via scanning electron microscopy (SEM), and scintillation characteristics were evaluated on the basis of the emission spectrum, light output, light response to x-ray dose, modulation transfer function (MTF), and x-ray images. Compared to control films without a reflective layer, CsI:Tl films with reflective layers showed better sensitivity and light collection efficiency, and the film with a $TiO_2$ reflective layer showed the best properties.

In this paper, we propose an accident-prevention smart monitoring system for Haenyeo(Woman diver) using Zigbee module and GPS sensor. This system can collect such information as the diving location, the body temperature, the depth of diving, and the diving time of a Woman diver working under the water and then respond immediately to an accident occurring. The research developed a smart Teawak and smart swimming goggles which can measure the state of a Woman diver and her diving activities. Smart Teawak, the buoy tool while a Woman diver is collecting seafoods under water, is able to receive GPS and transmit the data from smart swimming goggles and Zigbee Module to IHSS(IoT based Haenyeo Safety service Software) server. In addition, IHSS, a responsive web, provides the diving location and the state of a Woman diver on the smart phone. As a result, the system will be useful in the aspects of Woman diver' health care and the safety, furthermore, which will significantly contribute to global marketing of Woman diver with its being designated as a UNESCO intangible cultural asset.

Recently, research about ESS(Emergency Support System) has been actively carried out to provide a variety of medical services using smart devices and wearable devices. Smart healthcare provides a personalized health care service using various types of bio-signal measuring sensors and smart devices. For the smart healthcare using a smart device, it is need to research about personal health monitoring using a smart wearable devices, and also need to research on service methods for first aid measures after an emergency. In this paper, we proposed about group management based emergency support system, that is monitoring about personal bio signal using smart devices and wearable devices to protect patient's life. The system notices to the medical volunteers based on the position information when an emergency situation. In addition, we have designed and implemented an emergency support system providing the information of the patient on the display when transmitting a picture of a patient using a smart device to the server.
