The Connected House is a new type of IT convergence service that combines new communication services with existing IT systems such as M2M, NFC, smart home, and smart grid. It is a future connected life service that connects to any device anytime, anywhere. In this paper, we designed an intelligent gateway, a connected office solution for the Internet of things, which provides a connected life service for the future, and can control various sensors, ZigBee/Z-Wave/NFC and terminal devices. In addition, IP/SIP/IMS cameras and video door phones that are linked to the gateway have been developed to satisfy the quality standards of domestic communication service providers in terms of voice quality, jitter, and frame rate.

The TA-50 aircraft is conducting simulated training on various situations, including air-to-air and air-to-ground fire training, in preparation for air warfare. It is also used for pilot training before actual deployment. However, the TA-50 does not have the ability to operate smart weapon forces, limiting training. Therefore, the purpose of this study is to implement the TA-50 aircraft to enable virtual training of one of the smart weapons, the Point Direct Attack Munition (JDAM). First, JDAM functions implemented in FA-50 aircraft, a model similar to TA-50 aircraft, were analyzed. In addition, since functions implemented in FA-50 aircraft cannot be directly utilized by source code, algorithms were extracted using machine learning techniques(TensorFlow). The implementation of this function is expected to enable realistic training without actually having to be armed. Finally, based on the results of this study, we would like to propose ways to supplement the limitations of the research so that it can be implemented in the same way as it is.

Our daily lives have changed a lot because of the COVID-19 pandemic. This is essential to reduce the spread of COVID-19 due to public health measures such as social distancing. At the same time, however, they are exposed to depression, anxiety disorders, depressive disorders, trauma and stress-related disorders. For this, we developed an application that can check HRV data and stress index by measuring ECG and PPG based on a Smart Watch device that can measure bio-signals in real time. In the case of the developed application, the heart rate is measured and displayed in real time to deliver basic exercise information by measuring exercise, steps and calories, and total distance, and smoothly based on blood pressure, heart rate, and HRV data as a measurement program. Through this, I believe that the IoT Smart Stress Care Application, which can manage mental health by itself, will be helpful to patients with stress and depressive trauma disorders.

SDR(Software Defined Radio)은 여러 세대의 이동 통신 시스템 무선방송 및 다양한 통신 시스템이 존재하는 환경에서 소프트웨어 업그레이드로 무선장치 및 서비스를 제공할 수 있는 효율적인 해결 방안으로 대두되고 있다. SDR 이라는 기술은 하드웨어 수정 없이 모듈화 된 소프트웨어의 변경만으로 단일의 송수신 시스템을 통해 다수의 무선 통신 규격을 통합 수용하는 무선 인터페이스 기술이다[1]. 이러한 기술을 실현하기 위해서는 소프트웨어 다운로드 기술이 매우 중요하게 된다. 왜냐하면 시스템에 프로그램을 다운로딩해서 하드웨어가 Reconfiguration 되어 사용자가 원하는 대로 시스템이 셋팅이 될 수 있어야 하기 때문이다. 소프트웨어 다운로드 방법에는 크게 공중파를 이용하는 방법, 컴팩트한 이동식 디바이스로부터 다운로딩 받는 방법, 전화나 케이블 서비스 등을 통해 근거리/원거리 호스트 서버로부터 소프트웨어를 다운로딩 받는 방법, 네트워크를 통해서 소프트웨어를 다운로드 하는 방법 등이 있다[2]. 이 중에서 본 논문에서는 SDR을 위한 임베디드 시스템을 구현 하였고, 리눅스 포팅을 하였으며 스마트 카드를 이용한 소프트웨어 다운로드 방범을 제시함으로써 SDR 의미 구현을 시도해 보았다.

모든 농업은 수작업으로 시작해 수작업으로 끝나는 매우 힘들고 번거로운 작업이 많습니다. 여기에 보다 더 좋은 품질을 만들기 위해 많은 관심과 기술을 요한다. 그래서 본 논문에서는 드론과 라즈베리파이를 이용하여 온도, 습도 측정을 통해 보다 효율적인 수집이 이루어지고 이에 대한 피드백으로 좋은 주변 환경을 조성시켜 준다. 또, 드론에 무선 충전 모듈을 설치하여 자가 충전을 지향하여 번거로움을 지양했다. 마지막으로 드론에 일명 '트랙바퀴' 설치로 공중 비행 및, 지상 이동을 활성화 시켜서 이동성 향상시켰고 추락 시에도 움직일 수 있는 안전함을 보였다.

스마트시티 개념의 등장과 함께 국민의 삶의 질에 대한 정부의 관심이 증가하고 있다. 국민의 삶의 질을 향상시키는 것은 하수도와 같은 도시기반시설이며, 정부에서는 이를 지속적으로 유지관리 하여 주거환경 개선, 공중위생관리, 침수방지 등을 위해 노력하고 있다. 최근에는 하수시설의 노후화 와 서비스 범위의 변화에 따른 하수 서비스 품질에 대해 국민적 관심이 증가하고 있다. 또한 급격한 기후변화에 따른 도시 침수와 같은 재해가 빈번하게 발생함에 따라 재난 관리 측면에서도 하수도는 매우 중요한 비중을 차지하고 있다. 본 논문에서는 모바일 디바이스와 IoT 기술을 활용하여 하수시설 모니터링 시스템을 설계하였다. 제시하고 있는 시스템은 하수시설의 데이터를 수집하고 모바일 어플리케이션을 통해 사용자에게 알려준다.

Health geography has gained importance due to healthy smart cities, regions, and the integration of geo-internet and blockchain technologies. This study explores the intersection of geography and health, focusing on specific health challenges faced by individuals and groups. Using observational and descriptive methods, the study takes a regional approach to illuminate the socio-economic factors that are critical to addressing global health challenges. Drawing on academic literature and practical research, a concise case study of health challenges in Uzbekistan is presented, offering valuable insights. The analysis of data from informative articles and UN publications highlights the interdisciplinary nature of health geography and its practical applicability for researchers and policymakers. The findings underscore the important role of geography and health sciences in addressing region-specific diseases while highlighting the importance of spatial analysis in understanding environmental hazards and health impacts, including disease outbreaks.

Major viruses infecting rice are transmitted by planthoppers such as small brown planthopper (SBPH), brown planthopper (BPH) and white-backed planthopper (WBPH). In this study, we investigated planthoppers captured during 2015 to 2017 by a smart sky net trap (SSNT) system installed in 40 areas in Korea, which is an automatic, rapid and real-time insect surveillance system. The average rates of captured migration plnathoppers was 27.5%, 17.2%, 15.3% and 10.9% in Chungcheongnamdo, Jeollanamdo, Jeollabukdo and Gyeonggido, orderly. The highly migrated month was July for SBPH, July to August for WBPH and August for BPH. To investigate the viruliferous rates of planthoppers of rice during 2015 to 2017, we performed RT-PCR using specific primers for each rice virus. RBSDV was detected from 0.4% in SBPH, while no viruses were detected in BPH and SBPH. Rice planthoppers exist all around in Asia. They can move long distance by wind from southern countries to Korea. Monitoring the migration of rice planthoppers and their viruliferous rates is important to prevent the outbreaks of rice virus diseases.

The rapid increase of ageing population and chronic disease patients cause high medical expenses, and it led an increased attention to digital healthcare. Smart car technologies for healthcare have been developing to recognize drivers' status and predict diverse driving environments. The present study aimed to understand the research trends of autonomous vehicle technologies of Korea and the United States through time series analysis, network analysis, visualization, and comparison between the two countries. The results suggest that cooperative study needs to be done in common research areas such as driver's safety and algorithms. It is also needed to conduct studies and benchmark about liking technique related to part-to-part and vehicle-to-vehicle as America's competitive advantaged area. In the US, diverse approaches of autonomous vehicle technologies have used to consider the characteristics of various age groups and passengers' health status through sensor, while in Korea, only one aspect, older drivers, is mentioned. Implications for the development direction of autonomous vehicle technologies with competitiveness in considering public health, ethics, and driver's safety and convenience are discussed in detail.
