In construction structure management, the effects of investigation by the professional manager is dependent on the cost, the inspection periods and methods. Therefore, effective and automated maintenance system for the target structure is required. Although some bridge monitoring systems are operating using wire based networks, the performance is not good enough to show sufficient ability as integrated bridge management system. In this paper, we design and implement an integrated bridge management system based on sensor networks. Two expert modules for bridge management and the integrated system management are provided. Moreover, web-based monitoring system is also designed for users at anywhere. The results show that the system is effective and readily available.

The communication issues expected for SMEs are that 1) IT systems are not easy to connect, 2) data collection and integration by heterogeneous systems are difficult, and 3) various fieldbuses and protocols make interfaces difficult. Usually, SMEs often have automation built before the introduction of smart factories. It is necessary to provide communication technology such as Sensing to meet the heterogeneous system level with the old aged sensors in the automation equipment and communication network of SMEs. We will consider how to improve the network interface before applying the latest network technology at the time of preparation using PI.

다양한 플랫폼 상에서 응용 시스템에 대한 개발, 배포, 운영의 고생산성과 고품질을 얻기 위해서는 소프트웨어 구성 요소들의 체계적인 재사용 접근과 자동화된 도구의 지원이 요구된다. 함수나 클래스 라이브러리에서 설계 패턴과 프레임워크, 그리고 최근의 상업적인 비즈니스 컴포넌트에 이르기까지 여러 재사용 방법이 제시되었으나 기대만큼의 확실한 효과를 얻을 수 없었다. 설계 패턴은 설계 경험에 대한 캡슐화된 빌딩 블록으로 개발 응용의 표준화된 아키텍쳐 제공을 통해 응용 도메인의 한정성과 클래스 수준의 재상용의 복잡성을 극복할 수 있다. 응용 개발의 표준 아키텍쳐로서의 웹을 통한 재사용 요소들의 공유는 여러 개발자들에 의한 다양한 도메인 요소로서의 전개와 동적이며 실시간적인 라이브러리 관리가 가능하다. 본 논문에서는 웹 환경 하에서 자동화된 설계 패턴 재사용 환경 구축을 목적으로 한다. 그러므로 For Reuse 관점에서 서버 상에 각 도메인별 패턴 라이브러리를 구축하며 With Reuse 관점에서 패턴 검색, 이해, 획들 그리고 재구조화를 통한 응용으로의 재사용 지원기를 구축한다. 본 시스템은 패턴의 공유에 의한 유사 도메인 응용의 표준화를 유도하고 사용자의 패턴 재정의에 의한 자생적을 확장 가능한 패턴 라이브러리 제공이 가능하다. 또한 이를 위해 도메인 분석을 통한 패턴의 행위와 의도를 기준으로 설계 패턴들을 분류, 카탈로깅하여 재사용 라이브러리를 제시한다.

The productivity of cultivated crops in Korea is low compared to the Netherlands, which is an advanced agricultural country. In addition, modernization of facility and complex environmental control technology are needed to overcome poor growth and productivity deterioration caused by shortage of sunshine, abnormal temperature and high temperature due to abnormal climate. On the other hand, domestic facility horticulture complex environmental control is a level of machine automation that can check the internal situation of a green house with a cell phone and remotely operate a sprinkler, heat cover, curtain, ventilator, Therefore, this paper suggests the development of optimum environment control technology for facility horticulture based on the growth model and the cultivation technology knowledge base in order to realize the automation of optimal complex environment control and contribute to improvement of quality and productivity of cultivated crops.

In modern society, artificial intelligence and automation are being applied in various fields due to the development of the 4th industrial revolution and IoT technology. In particular, systems with a high proportion of image processing, such as automated processes, intelligent CCTV, medical industry, robots, and drones, are susceptible to external factors noise. In this paper, we propose a digital filter based on noise estimation and weights to reconstruct an image in a complex noise environment. The proposed algorithm classifies the types of noise using noise judgment, and determines the noise level of the filtering mask to switch the filtering process to obtain the final output. In order to verify the performance of the proposed algorithm, simulation was conducted, compared with the existing filter algorithm, and the results were analyzed.

With the personal-media development that has emerged through various means such as UCC and SNS, many media studies have been completed for the purposes of analysis and recognition, thereby improving the object-recognition level. The focus of these studies is a classification of media that is based on a recognition of the corresponding objects, rather than the use of the title, tag, and scripter information. The media-classification task, however, is intensive in terms of the consumption of time and energy because human experts need to model the underlying media ontology. This paper therefore proposes an automated approach for the modeling of the media-classification ontology schema; here, the OWL-DL Axiom that is based on the frequency of the recognized media-based objects is considered, and the automation of the ontology modeling is described. The authors conducted media-classification experiments across 15 YouTube-video categories, and the media-classification accuracy was measured through the application of the automated ontology-modeling approach. The promising experiment results show that 1500 actions were successfully classified from 15 media events with an 86 % accuracy.

A considerable number of construction disasters occurs on pathway. A safety management in construction sites is usually performed to prevent accidents in activity areas. This means that safety management level of hazards on pathway is relatively minified. Many researchers have introduced that a hazard identification is fundamental of safety management. Thus, algorithms for helping safety managers' hazardous area identification is developed using automated data collection technology. These algorithms primarily search potential hazardous area by comparing workers' location logs based on real-time locating system and optimal routes based on BIM. And potential hazardous areas is filtered by identified hazardous areas and activity areas. After that, safety managers are provided with information about potential hazardous areas and can establish proper safety countermeasures. This can help improving safety in construction sites.

Field works are decreasing gradually since advancement of industrial robots. Tunnel cleaning is a dangerous field work which can be solved only by introducingadvanced tunnel cleaning automation equipment. Industrial robots work tirelessly night and day without a loss in performance. Consequently, greatly reduce the costs of manufactured goods.So far only 200 construction robots are invented. Robots used for tunnel cleaning are not of high standard they always need additional workers for job to be done. Robots offer specific benefits to workers, industries and countries. If introduced correctly for tunnel cleaning, industrial robots can improve the quality of life by freeing workers from dirty, boring, dangerous and heavy labor. Development of advanced tunnel cleaning automation equipment is a must to overcome above issues. The benefits of robots to industry include improved management control, productivity and consistently high quality products. This research is a study on tunnel cleaning automation equipment and introducing advanced tunnel cleaning automation equipment.
