Along with the recent increase in national income, social phenomena such as aging due to a decrease in population and an increase in single households are observed. There are also an increasing number of households raising pets in proportion to aging households and the increase in the number of single households, most of which use animal companions to overcome loneliness and boost domestic vitality. As more and more people consider pets as family members, the size of the domestic pet market is also growing. The growing number of pets in older households and single households is not properly managed by care such as food meals and exercise management for pets. It is necessary to research and develop robots that can monitor animal companions remotely, feed a certain amount of food at regular intervals, and manage their health through exercise. Among pet companions, dog selection is the highest. Therefore, this study identified robot research on driving methods, examples of existing pet care systems, and researched pet care robots using obstacle avoidance algorithms. In order to use the snack pay behavior and obstacle avoidance algorithm of the pet animals by applying IoT and we .oPI technology, it is able to use ultrasonic sensors on the front and has four infrared sensors on the back. However, this study does not reflect the characteristics of other pet animals as a study on pet care robots, and it requires continuous observation and testing.

The river network is one of the essential topographical characteristics in river management. The river network which as previously constructed by the ground surveying method has recently begun to be efficiently constructed using the remote sensing datasets. Since it is difficult to remove these obstacles such as bridges in the urban rivers, it is rare to construct the urban river networks with the various obstacles. In this study, the Sentinel-2 satellite imagery was used to develop the automatic method for detecting the urban river networks without the obstacles and with the preserved boundaries as follows. First, the normalized difference water index image was generated using the multispectral bands of the given Sentinel-2 satellite imagery, and the binary image that could classify the water body and other regions was generated. Next, the morphological operations were employed for detecting the complete river networks with the obstacles removed and the boundaries preserved. As a result of applying the proposed methodology to Han River in Seoul, the complete river networks with the obstacles removed and the boundaries preserved were well constructed.

The demand for the development of automated construction equipments is gradually increasing to deal with the current problems of construction technology, such as a lack of experienced workers, the aging of engineers, safety issues, etc. In particular, earth work such as excavation is very machine-dependent, and there has been a great deal of research on the development of an intelligent excavator, which involves great safety concerns. Thus, the objective of this study is to develop the technology to enhance the safety of intelligent excavation systems by developing an omnidirectional object detection technology for the intelligent excavator and applying it to a user-friendly system. The existing literature was reviewed, and the function of various sensor technologies was investigated and analyzed. Then, the best laser sensor was selected for an experiment to determine its effectiveness. An omnidirectional object detection algorithm was developed for a user interface program, and this can be used as the fundamental technology for the development of a safety management system for an intelligent excavator.

For safe operation of ships and management of marine fisheries farms, the data set that extracts the boundaries of marine fisheries farms can provide information on obstacles in the vessel's navigation path in advance by examining whether it matches the fishing ground permit area. In addition, it can be used to determine whether fish farms are operating to compensate for damage caused by marine accidents, and the relevant local government can use it to manage fishing grounds. It is also highly utilized as basic data to identify obstacles for safe navigation of ships. In this study, Sentinel-2 satellite image data from the European Space Agency (ESA) was used to extract the boundaries of fish farms. From the video image, the fish farm's status data by cycle was divided into five zones: Busan-Ulsan area, Geoje-Changwon area, Goseong-Tongyeong area, and Namhae-Sacheon area. Through the image highlighting process, the farm boundary data and meta data were processed and extracted.

Smart Highway is the intelligent highway that improves a traffic safety, reduces incidence of traffic accidents, and supports intelligent and convenient driving environment so that drivers can drive at high speeds in safety[1]. In order to implement the highway, it is required to gather a dangerous data such as obstacle, wild animal, disabled car, etc. To provide the situation information of the highway, it has been gathered traffic information using various sensors. However, this technique has problems such as the problems of various information gathering, lack of accuracy depending on weather conditions and limitation of maintenance. Therefore, in order to provide safe driving information to driver by gathering dangerous condition, radar system is needed. In this paper, we used a developing 34.5GHz RWR(Road Watch Radar) radar for gathering dangerous information and we verified performance of obstacle detecting and resolution through field test.

현재의 오피스는 공간이 좁고, 바닥위의 배선이 장애물이며, 형광전구가 노출된 조명으로 실내 작업환경에 대한 고려가 매우 미약한 점에 의심할 여지가 없다고 생각된다. 특히 OA기기의 도입에 따른 집무 공간의 감소, 프린터 소음, 기기의 발생열, 배선, VDT(Visual Display Terminal:화면이 있는 OA기기) 작업과 관련된 환경 관리, 작업관리, 건강관리의 필요성등의 문제가 발생하고 있다. 그러므로 쾌적한 분위기를 구성요소로 조명은 실의 LAY OUT, 표면처리, 배색등 인테리어 디자인과 함께 그 효과를 최대한으로 연출하도록 되리라 생각된다. 따라서, 자연채광 이용을 통하여 절감될 수 있는 인공조명(형광등)의 제어방법으로서 본 논문에서는 점멸방식(ON,OFF)을 시도하였으며 점멸에 따른 급격한 조도저하를 보다 심리적인 차원을 고려한 실내조명 조광장치(천정형태와 외부에 댄 반사판)로 인한 실내조도 분포의 영향에 대하여 파악하고자 하였다.

최근 들어 개인정보 유출 사고가 빈번히 발생하고 있어, 개인정보 보호를 위한 법제도적 대책뿐만 아니라 기술적 보호대책의 강화가 요구되고 있다. 그러나 국가마다 지역마다 서로 다른 개인정보보호관련 법 제도적 요구사항의 상이는 서로 다른 보호조치 수준을 초래하며, 이는 궁극적으로 국가 간 또는 지역 간 개인정보의 자유로운 이전의 커다란 장애물이 되고 있다. 따라서 글로벌하게 합의된 프라이버시 원칙이 요구되었으며, 이에 기반을 둔 보호대책(control)의 개발이 필요하게 되었으며, 이 보호대책은 기업에 의해 수립되는 개인정보보호관리체계 (PIMS, personal information management system)의 인증 기준이 되며, 개인정보관리체계의 인증은 국가간 개인정보보호의 원만한 이동을 가능케 할 것이다. 본 논문에서는 각각 경제협력개발기구(OECD), 아시아태평양경제협력기구(APEC), 그리고 국제표준화 기구인 ISO/IEC, 그리고 한국 정보통신기술협회(TTA) 정보통신단체표준에서 정의된 프라이버시 원칙을 살펴보고, 각 프라이버시 원칙을 비교한다. 또한, 최근 구글의 개인정보통합관리에 대응할 수 있는 비연결성(unlikability) 원칙을 포함한 추가적인 프라이버시 원칙도 제시한다. 참고로 본 논문의 내용은 TTA 표준[4] 개발 시에도 반영 되었다.
