Most construction disasters are analyzed to be human factors such as not complying with the safety regulations of construction sites, not using clothing and protective equipment, safety insensitivity, and the health of workers. In order to prevent such a construction disaster, the project site management needs to check the health of workers, but it is difficult to check the condition of workers every hour. Therefore, this paper proposed the design of digital safety-helmet that can automatically identify health conditions by checking workers $SpO_2$ and pulse rates, away from simple protective features.

Today, the Internet of Things is used in many places, including homes, industrial sites, and hospitals, to give us convenience. Many services generate new value through real-time data collection, storage and analysis as devices are connected to the network. Many of these fields are creating services and applications that utilize sensors and communication functions within IoT devices. However, since everything can be hacked, it causes a huge privacy threat to users who provide data. For example, a variety of sensitive information, such as personal information, lifestyle patters and the existence of diseases, will be leaked if data generated by smarwatches are abused. Development of IoT must be accompanied by the development of security. Recently, Differential Privacy(DP) was adopted to privacy-preserving data processing. So we propose the method that can aggregate health data safely on smartwatch platform, based on DP.

더 건강하고 더 행복하게 살자는 참살이 열기는 대단하며 또한 참살이를 추구하는 자세는 조금도 잘못되지 않았다. 그러나 불확실한 소문에 휩쓸린 참살이 광풍은 절대 도움이 되지 않는다. 특히 먹을거리의 현명한 소비도 합리적인 생산만큼이나 중요한 과제다.

이와 같이 태어난 지 한 달 이내의 아기들은 어머니 체내에서 모든 보호를 받고 있던 태아기에서 벗어나 출생 후 혼자 힘으로 살아가기 위한 적응을 하는 기간이므로 여러 가지 면에서 약하며, 여러 가지 질병에 걸릴 위험 또한 많기 때문에 적절하게 관리해 주는 것이 매우 중요하다.

유해물질 잔류허용 기준치를 넘게 되면 축산물은 시장판매가 금지되고, 사육자도 추적을 당하여 국민건강 보호차원에서 법적제재를 받으며,축산물에 대한 소비자의 불신으로 소비가 감퇴되는 등 직간접으로 큰 손해를 보게 된다.
