본 논문에서는 기존에 사용되고 있는 흔히 사용되는 텀블러에 사물인터넷을 접목시켜 좀 더 스마트한 텀블러를 제작하였다. 이 스마트 텀블러는 블루투스를 연동하여 어플리케이션을 통해서 하루 물 수분섭취, 권장량 설정, 남은 물의 양, 마신물의 양 등을 관리할 수 있다. 인바디를 통해 그 사람의 하루 물 권장량을 설정하여 그 권장량만큼 물을 마실 수 있도록 하였고, 텀블러의 뚜껑을 닫을 때 마다 초음파 센서로 값을 계산하여 어플리케이션에 값이 나오도록 정보를 새롭게 갱신한다.

시각장애인의 생활 편의를 도우기 위한 텀블러이다. 물을 받을때 물의 수위를 측정하여 얼마나 차있는지 수량을 음성으로 알려주는 기능 텀블러 내에 물 온도가 얼마나 뜨거운지를 온도센서를 통해서 알려주는 기능. 그리고 텀블러의 위치를 스마트폰에 입력을 통하여 소리로 그 텀블러 위치를 알려주는 기능이 있다. 이 3가지 기능을 아두이노로 구현 한다.

Recently, interest in the environment and well-being is increasing due to changes in people's level of consciousness. Accordingly, it is trying to reduce disposable products, and interest in "water diet" is increasing as a way to maintain a healthy body. Many people use portable tumblers to drink water or drinks, and in particular, recently, they have evolved into a smarter form that provides various functions to increase user convenience. Existing studies have limited drinks to "water," so there is a limit to monitoring various drinks. To solve this problem, this paper produced a smart tumbler that can judge drinks using IoT technology and monitor the intake of drinks. In addition, it became possible to measure the intake more accurately by judging the case of throwing away the beverage without drinking it. Based on the data of various IoT-based sensors, the user can identify the intake amount of each drink in a dedicated application and receive various conveniences.

Using small cameras such as smartphones, criminals shoot secretly in public restrooms and women's changing rooms. And Revenge porn is also increasing. As a result social damage is increasing. Tumblr is an overseas service and it is very difficult to work with Tumbler on international legal cooperation and deletions. Thus In order to block the distribution of videos, victims must find and report the video URL themselves. But it's hard for victims who lack IT expertise to proceed those procedure. In this study, we automatically collect the URL of stored information and hash values of the images from API permlink of Tumbler blog. It is then saved as a document file with and presented to the victim. Through these technical methods, we can help victims report violations easily and quickly.
