The most recent, Vacuum Pipeline for Waste Collecting System, to collect MSW(Municipal Solid Waste) efficiently, is used environmental preservative, to emit less air pollution, in New City. However, it is difficult to monitor broken pipe and filled mass of Waste, because Vacuum Pipeline is laid underground. Therefore, FBG, optical fiber sensor, is used to inspect the temperature change and longitudinal strain to take proper action for unusual situation. I have need to accumlate sensor data of district control. I hope to be used Vacuum Pipeline more than 30 years in New City.

Recently, wearable computers equipped with various biosensors such as smart watches, smart bands, and smart patches that support daily health management of users as well as patients have been released. Users of wearable computers such as smart watches face various difficulties in performing biometric information processes such as data sensing, collection, transmission, real-time analysis, and feedback in a weak wireless and mobile biometric information service environment. In particular, the biometric information collection interface is an important basic process that determines the quality and performance of the entire biometric information service. So far, research has focused on sensing hardware and logic. This study intensively considers the interface method for effectively sensing and collecting raw biometric information. In particular, the process of collecting biometric information is designed and analyzed from the perspective of periodicity. Therefore, we propose an efficient and stable periodic collection method.

개인정보보호 분야는 타 분야에 비해 통계 및 현황에 대한 정보가 부족하다. 또한 개인정보보호 분야는 정보화, 정보보안, 법 등 어느 분야에도 일방적으로 속하지 않아 부수적으로만 실태 파악이 되고 있어 앞으로도 한계가 있을 것이다. 본 논문에서는 약 11만 개의 개인정보처리자가 공개하고 있는 개인정보 처리방침을 이용하여 방대한 양의 데이터를 수집하고 저장하여 이를 분석할 수 있는 방안을 제시하고 실제 결과를 보여준다. 제시된 방안은 데이터의 품질이 보장되고 시간과 비용을 절감할 수 있어 기존 방식에 비해 결과에 대한 정확성과 현황 파악에 대한 신속성에 있어 유리하다. 또한 다양한 분석이 가능하여 개인정보보호에 대한 실태 파악의 새로운 돌파구 역할을 할 수 있다. 본 논문에서는 개인정보보호와 빅데이터 분야의 접목을 통해 개인정보보호의 발전 방안을 제시하고 있다.

This paper proposes a DRMS(Distribution Remote Management System) which can enhance highly the economics of automatic metering system and the power quality supplied to the electric customer improving the efficiency of the meter reading, voltage management and load management work by realizing the remote meter reading, the remote voltage management and the remote load management based on the ADWHM(Advanced Digital Watt Hour Meter). The DRMS is designed so that the voltage management and load management work in remote site can be processed by collecting the voltage pattern and current pattern as well as watt hour data from all ADWHMs one time every month regularly or from special ADWHMS several time irregularly, A new on-line voltage and load management strategy based on the ADWHM is designed by analyzing the existing voltage management and load management process. Also, DRMS is designed so that watt-hour data, voltage pattern data, load pattern data and power factor data can be collected selectively according to the selection of user to assist effectively the methodology. Remote management program and database of the DRMS are implemented based on Visual C++, MFC and database library of MS. Also, DRMS is designed so as to communicate with the ADWHM using RS232C-TCP/IP converter and ADSL. The effectiveness of the remote metering function is proven by collecting and analyzing the data after ADWHMs installed in any site. The developed strategy and program also is verified through the simulation of voltage management and load management.

The agricultural environment is changing and becoming more advanced due to the influence of the 4th Industrial Revolution. From the basic plan of Rural Informatics to the current level of 2nd generation smart farms aimed at improving productivity using Big data, cloud network and more IoT technology. We are continuing to provide support and research and development. However, many problems remain to be solved in order to supply and settle smart farms in Korea. The purpose of this study is to provide a method of collecting and sharing data on farming environment and to help improve the income and productivity of farmers based on collected data. In the case of hog farm, the multiple sensors for environmental data like temperature, humidity and gases and the network environment for connecting the internet were established. The environment sensor was made using the ESP8266 Node MCU board as micro-controller, DHT22 sensor for temperature and humidity, and MQ series sensors for various gases in the hog pens. The network sensor was applied experimentally for one month and the environmental data of the hog farm was stored on a web database. This study is expected to raise the importance of collecting and managing the agricultural and environmental data, for the next generation farmers to understand the smart farm more easily and to try it by themselves.

COVID-19, a highly infectious disease, has affected the globe tremendously since its outbreak during late 2019 in Wuhan, China. In order to respond to the pandemic, governments around the world introduced a variety of public health measures including contact-tracing, a method to identify individuals who may have come into contact with a confirmed COVID-19 patient, which usually leads to quarantine of certain individuals. Like many other governments, the South Korean health authorities adopted public health measures using latest data technologies. Key data technology-based quarantine measures include:(1) Electronic Entry Log; (2) Self-check App; and (3) COVID-19 Wristband, and heavily relied on individual's personal information for contact-tracing and self-isolation. In fact, during the early stages of the pandemic, South Korea's strategy proved to be highly effective in containing the spread of coronavirus while other countries suffered significantly from the surge of COVID-19 patients. However, while the South Korean COVID-19 policy was hailed as a success, it must be noted that the government achieved this by collecting and processing a wide range of personal information. In collecting and processing personal information, the data minimum principle - one of the widely recognized common data principles between different data protection laws - should be applied. Public health measures have no exceptions, and it is even more crucial when government activities are involved. In this study, we provide an analysis of how the governments around the world reacted to the COVID-19 pandemic and evaluate whether the South Korean government's digital quarantine measures ensured the protection of its citizen's right to privacy.

본 논문에서는 콘크리트 균열 이미지 데이터셋을 효율적으로 얻기 위한 합성곱 신경망 네트워크 학습 기반의 데이터 증강기법을 제안한다. 실제 콘크리트 균열 이미지는 정형화된 형태가 없고 복잡한 패턴을 지니고 있어 얻기 어려울 뿐만 아니라, 데이터를 확보할 때 위험한 상황에 노출될 우려가 있다. 이러한 상황에 노출된 데이터셋 수집 문제를 본 논문에서는 벡터와 두께 기반의 데이터 증강 기법을 통해 비용과 시간적 측면에서 효율적으로 해결한다. 또한 제안한 방법을 효율성을 입증하고자 U-Net기반의 균열 검출을 통해 다양한 장면에서 실험을 진행했고, IoU 정확도로 측정했을 때 모든 장면에서 성능이 향상되었다. 콘크리트 균열 데이터를 증강하지 않았을 경우 잘못 예측된 경우의 비율이 약 25%였으나, 우리의 방법을 통해 데이터 증강을 했을 경우 잘못 예측된 비율이 3%까지 감소하였다.

교통분야에서 탄소중립 달성을 위한 전략으로 자동차 총 주행거리 감축과 승용차 교통량 감축을 제시하고 있다. 이를 위해서는 대중교통 활성화를 목표로 MaaS 서비스를 적극적으로 추진하여야 한다. MaaS를 추진하기 위해서는 개인의 이동에 대한 이용수단, 경로뿐만 아니라, 개인의 이용 수단의 전환 등 개인별 누적 이동 데이터가 필요하다. 하지만 국내에서는 개인의 이동에 대한 데이터를 수집하고 이를 활용하는데 있어서 법적인 한계가 존재한다. 2023년 개정된 개인정보보호법에 개인정보 전송요구권이 신설됨에 따라 개인의 이동에 대한 데이터를 수집하고 활용하기 위한 법률이 마련되었지만, 시행령, 세부 규칙, 지침, 가이드라인 등이 마련되어야 하며, 마이데이터수집을 위한 데이터 형식 및 전송체계의 표준화가 선행될 필요가 있다.
