Currently, in Korea, a multi-seater lane (HOV) and a designated lane system are being implemented to solve traffic congestion. However, in both systems, it is difficult to crack down on cases of violations without permission, so people are required to be assigned to areas that want to crack down. In this process, manpower and budget are inefficiently consumed. To compensate for these shortcomings, we propose the development of an integrated enforcement system through YOLO, a deep learning object recognition model. If the two systems are implemented and integrated using YOLO, they will have advantages in terms of manpower and budget over existing systems because only data learning and system maintenance are considered. In addition, in the case of violations in which it is difficult for the existing unmanned system to crack down, the effect of increasing the crackdown rate through continuous learning can be expected.

Human resources are one of the most essential elements of an organization. In particular, the more closed a group is, the higher the value each member has. Previous studies have focused on personal attributes of individual, such as medical history, and have depended upon self-diagnosis to manage structures. However, this method has weak points, such as the timeconsuming process required, the potential for concealment, and non-disclosure of participants' mental states, as this method depends on self-diagnosis through extensive questionnaires or interviews, which is solved in an interactive way. It also suffers from another problem in that relations among people are difficult to express. In this paper, we propose a multi-faced diagnosis model based on social network analysis which overcomes former weaknesses. Our approach has the following steps : First, we reveal the states of those in a social network through 9 questions. Next, we diagnose the social network to find out specific individuals such as victims or leaders using the proposed algorithm. Experimental results demonstrated our model achieved 0.62 precision rate and identified specific people who are not revealed by the existing methods.

Ground water development skill growth and life circumstances improvement increase ground water use. So managerial difficulties and various problems about ground water occur. Poor ground water management organization, lack of management person, thoughtless development add ground water pollution and lack of water volume. And local excessive developments or abandoned well occur. This paper presents ground water management system model making use of GIS and helps effective management by realizing necessary analysis functions in ground water management system and ground management methods. Local information of ground water recorded and development data, site examination data made D/B. And linearment analysis data making use of a satellite image data, hydraulic test data, the quality of water examination data, these local characteristic values made out thematic maps and making use of these data can form elementary data of ground water modeling It makes easy to understand environmental development conditions and pollution source conditions about new ground water development location, linearment growth, DRASTIC, the quality of water examination. Ground water management system making use of these functions can choose right location of ground water.

80년대부터 국내에 도입된 CAD/CAM시스템은 금형 및 관련 제조업체, 자동차 제조업체, 플랜트 /조선업체 등에서도 제도, 설계 및 설계해석용, CAM을 이용한 NC 가공용 등으로 적용되고 있다. 그러나 CAD/CAM 시스템을 판매업체의 불충분한 교육과 아프터 서비스가 아직 미흡하여, 시 스템 사용업체의 경우 시스템 활용기술 부족, 기술인력 부족 등의 이유로 활용도가 높지 못하다. 그럼에도 불구하고 많은 업체들이 CAD/CAM 도입을 본격적으로 준비하고 있으며, 93년의 경우 90년에 비해 사용자수가 2배가 되리라는 전망이다. 많은 업체의 경우 인원절감, 시간단축, 경비 절감 등의 비용효과와 정밀도/정확도 효과 등의 업무수준 향상 효과를 기대하며 추진하고 있으나 표준화, 관리의 체계화 효과 및 기업이미지 개선, 직원의식 수준 향상 등의 상징적 효과도 크다고 볼 수 있다. 국내에 CAD/CAM 시스템 보급을 촉진하기 위해서는 소프트웨어의 한글화 작업이 이루어져야 하고 분야별로 다양한 데이터베이스가 구축되어야 할 것이며, 가격이 저렴하고 속 도가 빠른 형상 모델링 기술발전이 요구된다. 끝으로, 우리 실정에 맞는 CAD/CAM 소프트웨어의 국산화 작업이 우리가 풀어야 하는 최대 과제라 할 수 있다.

Recently, quality inspection and defect management have been considered as one of the major issues for increasing customer satisfaction and corporate image in domestic construction industry. However, the quality inspection and defect management have not been performed systematically because of insufficient field managers, the excessive amount of documents, complicated work process and difficulty in communicating construction information. Therefore, the field manager could not perform the quality inspection and defect management work in time as well as the reliability of recorded quality and defect data was decreased. The primary objective of this study is to propose a quality inspection and defect management system using information technology which enables field managers to efficiently gather the information of defection in apartment housing. It is anticipated that the effective use of the proposed system would be able to imp개ve communication among the related participants and systematically accumulate data that might be used in similar construction projects.

This study has designed the system that can manage the amount of exercise required for health management, viewing the health management courses which are currently being operated, register the desire courses and verifying the registered schedules and monthly health performances at a glance by using a mobile application. The advantage of health club management system is automatically transmits the daily exercise information to the server without a separate sensor through a simple QR scanning using a smart phone. Since the overall operating requirements of services and various facilities of health club is transmitted as the data to the remote server through a smart phone, users of various levels including workers, students, housewives, etc can easily access and use the health club management system using the WiFi, LTE, 3G, etc.

도로는 교통기능 외에 여러 시설물을 수용할 수 있는 사회 인프라구축의 공간으로 활용될 수 있기 때문에 서울시뿐만 아니라 각 지방자치단체에서는 이러한 공간을 활용하기 위한 도로점용공사는 매년 전국적으로 수만 건에 달하고 있다. 따라서. 매년 발생하는 도로점용공사의 차로과다 점용, 교통시설물 설치 부적절, 보행자 안전무시, 공사안내표지 부적절, 공사구간에서의 불법 주.정차 등의 문제점이 계속하여 발생.지적되고 있으나 이에 따른 관련 규정이 미흡하여 도로점용공사 시행자의 불법을 초래하고 있는 실정이다. 또한 서울시의 경우 시스템적 접근방법인 관련조례에 의해서 수행되기보다는, 교통자문회의로 운영되고 있으며, 관련 인원 및 법적 제재조치가 미약하여 도로점용공사의 효과적인 관리가 어려운 실정이다. 따라서 서울시 및 각 지방자치단체에서는 도로점용공사로 인한 보행자와 운전자의 통행권 확보와 안전상의 문제 등을 하루빨리 인식하여 도로점용공사에 따른 도로공사장 교통관리 규정을 법규화 하여 체계적으로 관리할 필요가 있다. 이에 따라, 본 논문에서는 도로점용공사에 따른 관련법 및 적용대상, 관련보고서 검토, 서울시를 사례로 한 공사중 교통처리방안 운영실태 및 문제점의 진단을 통하여 향후 도로공사장 교통관리 규정의 운영적 및 제도적 측면의 개선방안과 향후 추진방향을 제시하고자 한다.

The purpose of this study was to add CPTED to the information security area. The control items of ISO 27001 (11 types) and the application principles of CPTED (6 types) were mapped. And the relevance between the items was verified through the FGI meeting through 12 security experts. As a result of the survey, the control items with a relevance of at least 60% on average are security policy, physical and environmental security, accident management, and conformity. As a result, the comprehensive policy was shared with CPTED's items as a whole. The specialized control items are security organization, asset management, personnel security, operation management, access control, system maintenance, and continuity management. However, specialized control items were mapped with each item of CPTED. Therefore, information security certification and septed are related. As a result, environmental security can be added to the three major areas of security: administrative security, technical security, and physical security.
