Big data analysis is a technique for effectively analyzing unstructured data such as the Internet, social network services, web documents generated in the mobile environment, e-mail, and social data, as well as well formed structured data in a database. The most big data analysis techniques are data mining, machine learning, natural language processing, and pattern recognition, which were used in existing statistics and computer science. Global research institutes have identified analysis of big data as the most noteworthy new technology since 2011. Therefore, companies in most industries are making efforts to create new value through the application of big data. In this study, we analyzed using the Social Matrics which a big data analysis tool of Daum communications. We analyzed public perceptions of "Internet of things" keyword, one month as of october 8, 2017. The results of the big data analysis are as follows. First, the 1st related search keyword of the keyword of the "Internet of things" has been found to be technology (995). This study suggests theoretical implications based on the results.

In this paper, a smart elevator system was studied using real-time object detection technology based on YOLO(You only look once)v5. When an external elevator button is pressed, the YOLOv5 model analyzes the camera video to determine whether there are people waiting, and if it determines that there are no people waiting, the button is automatically canceled. The study introduces an effective method of implementing object detection and communication technology through YOLOv5 and MQTT (Message Queuing Telemetry Transport) used in the Internet of Things. And using this, we implemented a smart elevator system that determines in real time whether there are people waiting. The proposed system can play the role of CCTV (closed-circuit television) while reducing unnecessary power consumption. Therefore, the proposed smart elevator system is expected to contribute to safety and security issues.

In general, IoT(Internet of things) designate the intelligence technologies and services which interact all necessity information between human and things, things and thing and things and systems with all things connecting through the internet based. The smart home in present of IoT environment fuses the daily supplies/equipment which needs to use for the private life with the internet of things that is the fruit of the converged business through all most private consumption related in vastly. The concept of smart home has been built around early 2000s due to the spread of high speed internet and advanced of smart electronics and internet, furthermore influencing by the enhancement of wireless network and smart devices, it is advanced as a smart home within the internet of things environment. Smart home service inside the house which most closely implemented with personal life is being developed and advanced in various forms. These developments may exert a positive effect, but if it does not resolve the security issues for the smart home service, then it may cause a big plague of privacy and personal life.

In paddy rice farming, water management is a critical task. To suppress weed emergence during the early stages of growth, fields are deeply flooded, and after transplantation, the water level is reduced to promote rooting and stimulate stem generation. Later, water is drained to prevent the production of sterile tillers. The adequacy of water supply is influenced by various factors such as field location, irrigation channels, soil conditions, and weather, requiring farmers to frequently check water levels and control the ingress and egress of water. This effort increases if the fields are scattered in remote locations. Automated irrigation systems have been considered to reduce labor and improve productivity. However, the net income from rice production in 2022 was about KRW 320,000/10a on average, making it financially unfeasible to implement high-cost devices or construct new infrastructure. This study focused on developing an IoT-Based irrigation valve that can be easily integrated into existing agricultural infrastructure without additional construction. The research was carried out in three main areas: Firstly, an irrigation valve was designed for quick and easy installation on existing agricultural pipes. Secondly, a power circuit was developed to connect a low-power Cat M1 communication modem with an Arduino Nano board for remote operation. Thirdly, a cloud-based platform was used to set up a server and database environment and create a web interface that users can easily access.

The internet of things (IoT) using cloud computing is applied to nuclear industry in which the nuclear power plant (NPP) accident is analyzed for the safety assessment. The Fukushima NPP accident is modeled for the accident simulations where the earthquake induced plant failure accident is used for analyzing the cloud computing technology. The fast and reasonable treatment in the natural disaster was needed in the case of the Fukushima. The real time safety assessment (RTSA) and the Monte-Carlo real time assessment (MCRTA) are constructed. This cloud computing could give the practicable method to prepare for the future similar accident.

과거 유비쿼터스 기술의 출현 이후로 사물에 간단한 인식 센서를 이용한 형태의 서비스가 널리 보급되었고, 스마트 기기의 발달로 인해 PC가 아닌 환경에서도 인터넷을 사용하기 용이한 환경이 정착되어, 이들을 이용한 사물 인터넷 (Internet of Things) 환경이 빠르게 확산중이다. 본 논문에서는 상황 인식 서비스와 추론 서비스를 사물 인터넷 환경에 적용 시킨 스마트 홈 상황인식 추론 프레임 워크의 설계 및 구현을 서술한다. 해당 프레임 워크는 실질적인 상황 정보를 제공하는 이기종의 사물 인터넷 기기 간 데이터 타입을 수용하기 위해 온톨로지 언어인 OWL 규격을 사용하여 상황 정보를 수용하고, 룰 입력 모듈을 통해 다양한 환경을 모델링 할 수 있는 XML 규격의 서비스 룰을 입력받는다. 이후, 상황 정보와 서비스 룰을 기반으로 추론엔진을 통해 상황을 추론하여, 단순히 조건 만족 시 실행 구조가 아닌 상황 기반의 추론에 의한 서비스를 제공하게 된다. 프레임 워크를 활용 방안을 설명하기 위해 예제 방범 시나리오를 통해 해당 프레임 워크의 특징 및 서비스의 흐름을 서술한다.
