코로나 19 이후 도시 안전에 대한 관심이 높아지면서, 여러 기관에서 도시의 안전성을 평가하는 지표가 개발되어 활용되고 있다. 용산구는 2021년 사회안전지수 평가에서 1위로 선정되어 한국에서 가장 안전한 도시로 선정되었으나, 2022년 이태원 참사로 인해, 많은 인명 피해가 발생하기도 하였다. 이것은 도시의 안전을 평가하는 지표가 담지 못하는 영역이 있으며, 이에 대한 연구가 필요함을 의미한다. 본 연구의 목적은 국내·외 안전도시 모델을 살펴보고 이를 통해 각 모델의 차이점과 안전도시를 평가할 때 사용되는 지표를 검토하기 위한 것이다. 본 연구에서 11개 안전도시 모델을 수집하고 각 평가지표를 분석한 결과, 안전도시 모델은 세계보건기구의 국제 안전도시와 유엔재해경감기구의 국제안전도시와 같이 기관에서 인증을 하는 "프로그램 기반의 안전도시 모델"과, 기관별 안전 관련 평가지표의 점수에 의해서 안전도시 순위 및 등급이 결정되는 "점수기반의 안전도시 모델"로 분류할 수 있으며, 안전한 도시가 되기 위해서는 이 두 가지 모델이 상호 보완적으로 활용될 때 도시 안전을 위협하는 제반 요소를 전방위적으로 대응할 수 있음을 알 수 있었다. 안전에 대한 위협이 다양해짐을 고려해볼 때 안전도시를 평가할 때 디지털 보안, 보건 안전, 인프라 안전, 개인 안전, 환경 안전, 교통 안전, 화재 안전, 범죄 안전, 생활안전, 자살, 감염병 등을 종합적으로 고려하는 것이 타당하는 결론을 얻었다.

India is a developing nation and has come with comprehensive way in modernizing its reducing poverty, economy and rising living standards for an outsized fragment of its residents. The STEM (Science, Technology, Engineering, and Mathematics) education plays an important role in it. STEM is an educational curriculum that emphasis on the subjects of "science, technology, engineering, and mathematics". In traditional education scenario, these subjects are taught independently, but according to the educational philosophy of STEM that teaches these subjects together in project-based lessons. STEM helps the students in his holistic development. Youth unemployment is the biggest concern due to lack of adequate skills. There is a huge skill gap behind jobless engineers and the question arises how we can prepare engineers for a better tomorrow? Now a day's Industry 4.0 is a new fourth industrial revolution which is an intelligent networking of machines and processes for industry through ICT. It is based upon the usage of cyber-physical systems and Internet of Things (IoT). Industrial revolution does not influence only production but also educational system as well. IoT in academics is a new revolution to the Internet technology, which introduced "Smartness" in the entire IT infrastructure. To improve socio-economic status of the India students must equipped with 21st century digital skills and Universities, colleges must provide individual learning kits to their students which can help them in enhancing their productivity and learning outcomes. The major goal of this paper is to present a low cost, effective learning mechanism for STEM implementation using Raspberry Pi 3+ model (Single board computer) and Node Red open source visual programming tool which is developed by IBM for wiring hardware devices together. These tools are broadly used to provide hands on experience on IoT fundamentals during teaching and learning. This paper elaborates the appropriateness and the practicality of these concepts via an example by implementing a user interface (UI) and Dashboard in Node-RED where dashboard palette is used for demonstration with switch, slider, gauge and Raspberry pi palette is used to connect with GPIO pins present on Raspberry pi board. An LED light is connected with a GPIO pin as an output pin. In this experiment, it is shown that the Node-Red dashboard is accessing on Raspberry pi and via Smartphone as well. In the final step results are shown in an elaborate manner. Conversely, inadequate Programming skills in students are the biggest challenge because without good programming skills there would be no pioneers in engineering, robotics and other areas. Coding plays an important role to increase the level of knowledge on a wide scale and to encourage the interest of students in coding. Today Python language which is Open source and most demanding languages in the industry in order to know data science and algorithms, understanding computer science would not be possible without science, technology, engineering and math. In this paper a small experiment is also done with an LED light via writing source code in python. These tiny experiments are really helpful to encourage the students and give play way to learn these advance technologies. The cost estimation is presented in tabular form for per learning kit provided to the students for Hands on experiments. Some Popular In addition, some Open source tools for experimenting with IoT Technology are described. Students can enrich their knowledge by doing lots of experiments with these freely available software's and this low cost hardware in labs or learning kits provided to them.
