In this paper, we propose a methodology to deal with the IOT system gradually as the use of effective systems such as electronic devices, healthcare, smart cars, smart home, remote meter reading and telemedicine closely related to our real life in the IOT system An IOT integrated account solution is needed as a way to address these needs as the demand grows for the need to identify and manage how users access and use the system for what period of time and at what point in time. We propose the communication algorithms for endpoint system, IOT system management rights policy, user information, and how to apply them to IOT system smart car and smart home on each object internet.

This study aims to develop a sort of expert system to simulate Internet of Things (IoT) service in architectural design alternatives and enhance the simulation performance using building information. The proposed protype system, named iotBIM, visualizes human behaviors and IoT services in a virtual place that is automatically generated from among design alternatives. We use commercial building information modeling (BIM) authoring tool for the development of iotBIM. The decision to develop iotBIM on the BIM platform was made because BIM tools already generate precise 3D models of design alternatives; iotBIM is plugged into the BIM tool as a simulation module. In the midst of the design process, architectural designers can activate iotBIM to investigate and establish IoT services that accord visually with design alternatives. The purpose of this study is to provide a theoretical and technological basis for the ultimate goal of this study.

IOT는 복잡하고 이질적인 네트워크 환경이며 저전력 장치를 위한 새로운 라우팅 프로토콜의 존재로 인해 혁신적인 침입탐지 시스템이 필요하다. 특히 접근이 어려운 IOT 환경에서는 공격을 받았을 때 정확하고 빠른 탐지가 용이하여야 한다. 따라서 본 논문에서는 탐지의 정확성과 희소의 공격을 잘 탐지하기 위한 효과적인 특징 추출과 분류를 위한 SAR(Stacked Auto Encoder+Random Forest) 시스템을 제안한다.

As a lexical meaning, casino is defined as "a certified gambling house, equipped with recreational facilities such as dance and music, etc., where people play roulette or cards." Casinos started from 17th to 18th century for European nobility and their social meetings and established a casino industry framework in the United States in the 1930s. The success of the casino business leads to the increase of sales; it became very helpful for the local and national government revenues and also for the related incidental tasks. Casino operations include a variety of fields, such as general customer management, dealer game management, security, account management, currency exchange, re-exchange management, marketing management, comp management and placement management, etc. These operations should be organically connected to each other by information systems such as a groupware, ERP and Customer Relationship Management (CRM), etc. In addition, in order to effectively manage comprehensive entertainment service, including accommodation and tourism, it is necessary to develop an information system which supports casino business and collateral entertainment service, collects the data generated throughout the business and provides information about the situations of management. Thus, this study will propose a casino information system designed and implemented, considering these details.

Ka-band payload of COMS (Communication, Ocean and Meteorological Satellite) launched in June 2010 was developed by ETRI with Korean local companies and also the in-orbit test (IOT) for the Ka-band payload was carried out entirely with domestic technology. The Ka-band payload IOT consisted of the antenna pattern measurements and the payload RF performance test was performed during about 40 days from 10 days after the launch. In this paper, the IOT methods and the results for the Ka-band payload are described in detail. According to the comparisons of each IOT test result with the corresponding ground test result, we can show that the Ka-band payload IOT and verification was successfully achieved and that all Ka-band channels of COMS are to be normal.

IOT middleware is required to play a pivotal role in interpreting, managing, and controlling data information of Internet devices (sensors, etc.). In particular, the root industry has different process flows for different industries, and there are various data processing requirements for each company. Therefore, a general purpose IOT middleware is needed to accommodate this. The IOT middleware structure proposed by this paper is a plug-in that can be used as an engine part for middleware basic processes such as communication, data collection, processing and service linkage, We propose a flexible and effective smart process for root industry. In addition, we propose a method to strengthen prevention and security against tampering, deodorization, etc. through encryption of network data between middleware plug - in and related service layer. We propose a system that will be developed as an IOT middleware platform that is specialized in the root industry so that it can be extended in various network protocols such as MQTT, COAP, XAMP.

본 논문에서는 작물재배에 대한 전문지식이 없는 초심자를 위하여 IOT를 이용하여 작물 재배에 필요한 데이터를 취득하는 시스템을 제안한다. 베이비 붐 세대의 은퇴가 진행되면서 도시농업의 증가와 정밀 고소득 장물에 대한 수요가 증가되고 있어 이에 필요한 작물의 재배자료에 대한 중요성이 증대되고 있다. 이에 각각의 작물에 따른 최적의 재배데이터를 계측하여 데이터베이스로 구축에 관한 연구를 진행하고자 한다. 작물 재배 데이터의 취득은 작물 데이터를 취득하는 계측 및 제어부와 계측데이터를 수집하고, 수집된 데이터를 기초로 작물재배 데이터를 처리하는 서버부분으로 구성되며, 계측 및 제어부에서 재배환경의 온도, 습도, 그리고 광량, 수분공급시기, 영양분 투입 데이터를 계측하여 일정 시간마다 서버로 저장한다. 따라서 본 논문에서 구축하고자 하는 IOT를 이용하여 작물 재배에 필요한 데이터는 최적의 작물 생장환경을 지속적으로 제공하여 비전문가의 농업활동에 새로운 방향을 제시하리라 사료된다.

스마트빌딩에서는 시설물에 대한 효과적인 관리체계 및 안전관리체계를 구축하는 것이 매우 중요하다. 지하 매설관의 경우에는 유속, 유량계 등의 센서를 설치하여 관로 흐름을 상시 감시하며, 노후되거나 슬러지가 축적된 관로는 문제가 발생하기 전에 교체 공사를 지시 할 수 있어야 한다. 본 논문에서는 하수(오수, 우수)도 맨홀 내 정보를 감지하여 실시간으로 전달, 판단, 처리 및 제어 할 수 있는 M2M/IOT 기반의 하수(오수, 우수)도 맨홀 내 모니터링 시스템을 설계 구현한다.
