The purpose of this study is to investigate what factors buyers buy in smart band purchasing. Especially, The study was conducted the perception of smart bands, focusing on personal healthcare, which is one of the biggest concern of today's people, and investigating the needs of users. SmartBand is the product with the highest market share in the wearable device market. It is an indicator of how much modern people are interested in their healthcare. Therefore, this study investigates non-users who are not currently using smart bands, and what factors to consider when buying smart bands. As a result, it was found that the design of the product and the hardware performance are more important than the smart band's personal health care function in purchasing the smart band, and fundamentally, the smart band itself was not needed. Especially, people aged 20-30 years have been burdened with using smart bands continuously.

As smart bands make life more convenient and provide a positive lifestyle, many people are now using them. Since smart bands deal with private information, security design and implementation for smart band system become necessary. To make a trustworthy smart band, we must derive the security requirements of the system first, and then design the system satisfying the security requirements. In this paper, we apply threat modeling techniques such as Data Flow Diagram, STRIDE, and Attack Tree to the smart band system to identify threats and derive security requirements accordingly. Through threat modeling, we found the vulnerabilities of the smart band system and successfully exploited smart bands with them. To defend against these threats, we propose security measures and verify that they are secure by using Scyther which is a tool for automatic verification of security protocol.

본 논문에서는 최근 황사 및 미세 먼지 등으로 늘어나는 환경적 오염으로부터 어린이들이 올바른 마스크 사용을 할 수 있도록 스마트 기능이 포함된 마스크를 제안하는 것이다. 제 4차 산업혁명으로 인하여 사물인터넷이나 스마트 제품은 날로 급증하고 있는 추세이다. 따라서, 어린이들이 많이 사용하는 마스크 제품에 스마트한 기능을 넣고자 한다. 스마트 밴드를 통해 미세먼제 오염도를 측정할 수 있고, 호흡 상태를 파악하고 분비물의 상태를 분석할 수가 있다. 따라서 의료기관을 방문하기 전까지 어린이들의 건강상태를 보다 즉각적으로 파악할 수가 있다.

We are entering a phase of an aged society. The societal expense on health care for the so called "silver generation", which refer to as those over the age of 65 is increasing. Although many companies provide various services based on information technology for the health of the silver generation, many have pointed out the limits of them, preventing the activation of services. This study tries to develop a new smart health band business model, which is the most common form of healthcare service that reflects the user's desire. To do this, the study will cover the smart health band and the technical functions related to it, as well as the elements of the business model and its content.

Today all kinds of smart devices are being developed with various researches on wearable devices that support smart computing on the human body. Skin diseases continue to rise including freckles, pimples, atopy, and scalp trouble due to the environmental and genetic factors, and people pay bigger medical bills to treat their skin diseases. There is thus a need to develop a smart-phone or table-based smart healthcare imaging system of high portability and diagnostic accuracy capable of analyzing and managing various skin problems related to skin care. This study proposed an integrated system combining the Smart Mi Band, a wearable device using moisture and UV sensors based on IoT, on the hardware part with the sensor information monitoring software.

대부분의 작업환경에서는 여러 가지 위험요소로 인한 안전사고가 자주 발생한다. 추락이나 작업환경의 붕괴 등 안전사고 발생시, 작업자가 관리자에게 응급상황을 전해야하지만, 사고로 인해 작업자가 원활하게 몸을 사용하지 못하는 경우에는 응급상황을 전달하는데 문제점이 발생한다. 본 논문에서는 이러한 문제를 해결하기 위해서 블루투스로 스마트폰에 응급상황을 전할 수 있는 웨어러블 단말기와 스마트폰의 WI-FI나 LTE망을 사용하여 작업자의 상황을 실시간으로 모니터링 할 수 있는 안전 시스템을 설계한다.

In modern society, awareness of diabetes is growing with an increase in the elderly population and an increase in the incidence of diabetes. In particular, diabetic patients can suddenly develop hypoglycemic shock; therefore, it is important to measure blood glucose periodically. However, self-monitoring blood glucose meters are difficult to carry and it is difficult to manage the value. To solve these problems, the blood glucose measurement system has been developed as a sensor attached to the body or as one of the functions of smart devices, but it has not been commercialized. In this paper, we propose a smart band with a blood glucose measurement function. If a user enters a schedule to measure blood glucose level, such as before/after meals, in the app, he/she can receive a measurement alarm from the band. The user can measure the blood glucose level at any time using the band, and the measured value is transmitted and managed by the app including behavior history such as before/after meals and the time. This will help the user to manage, diagnose and prevent health problems. The system has been tested using two medical device-certified products, and each blood glucose measurement value has been confirmed to be more accurate.

헬스케어와 IT가 결합한 융합산업이 발전하면서 웨어러블 디바이스와 스마트폰을 연계하여 운동정보를 제공하는 제품이 증가하고 있다. 특히 손목에 착용하는 스마트밴드를 통해 생체신호 및 움직임을 감지하고 신체상태 및 활동량을 제공하고 있다. 그러나 단순한 운동 동작의 횟수나 시간만을 알려주는 서비스를 제공하고 있어 정확한 운동 및 건강의 관리가 힘들다. 이에 본 논문에서는 사용자에게 운동의 정확성 여부를 알려주고 건강 및 운동에 대한 통계 정보를 제공하는 클라우드 서비스 기반의 운동 정보 제공 시스템을 제안한다. 제안 시스템은 스마트밴드와 모션 디바이스를 통해 모션 및 심박데이터를 취득하여 스마트폰을 통해 실시간으로 운동의 정확도 여부 및 활동 정보를 제공한다. 또한 클라우드 플랫폼의 서비스 가상 머신을 통해 세밀한 운동 자세 및 운동량, 신체 상태 통계 등의 피드백 서비스를 제공한다.
