  • 스마트워크란 시간과 장소의 제약 없이 업무를 수행하는 유연한 근무형태를 말한다. 스마트워크 근무 유형에는 가정에서 본사 통신망을 접속해 업무를 수행하는 재택근무와 주거지 인근 원격사무실에 출근하는 스마트워크 센터 근무, 그리고 스마트폰 등을 이용해 현장에서 업무를 수행하는 이동근무가 있다. 스마트워크를 통하여 기업들은 업무 효율과 생산성 향상시킬 수 있다. 또한 대도시 교통 혼잡을 줄이고 여성의 육아부담을 줄일 수 있어 정부에서 확대 지원하는 사업이다. 하지만 스마트워크의 특성상 원격으로 접속하여 업무를 처리하므로 공격자가 로그인 정보를 취득 시에는 위협이 존재한다. 또한 스마트워크 센터에서 사원 관리 취약성과 비인가자에 대한 접근이 용이하기 때문에 문제가 될 수 있다. 이에 따라 본 논문에서는 QR코드를 이용한 승인 인증 시스템을 제안하게 되었다.

  • 본 논문에서는 유아보호를 위한 차량용 스마트 알림 시스템을 설치해야 한다는 것을 제안한다. 여름철 유아들이 차량에 갇혀 숨지는 안타까운 사건이 빈번히 일어났다. 현행 도로교통법에서는 어린이 통학버스를 운전하는 사람은 운행을 마친 후 어린이나 영유아가 모두 하차했는지를 확인 하도록 규정하고 있고 통학차량에 일정 인원 이상의 유아들이 탑승하면 통솔인원교사가 등.하교 길에 동행하도록 의무화 되어 있다. 그럼에도 불구하고 여전히 통학차량에 유아들이 방치되어 사망하는 사건사고가 일어나고 있다. 외국에는 챠량 내부의 모든 버튼을 인식 하여야 차량의 시동이 멈추게 된다. 하지만 유아를 차량에 두고 나오는 사고가 났다. 차량용 스마트 알림 시스템은 기존 버스 내부에 RF카드를 인식하면 유아의 학부모에게 문자가 전송되게 되며 차량 어디에 위치하였는지 표시가 되게 된다. 이로인해 차량에 유아를 두고 내리는 일이 없게 되며 유아가 차량을 언제 탑승하였는지 확인할 수 있게 된다.

  • Autonomous driving technology, when commercialized, has the potential to improve the safety, mobility, and environmental performance of transportation networks. However, safe autonomous driving may be hindered by poor sensor performance and limitations in long-distance detection. Therefore, cooperative autonomous driving that can supplement information collected from surrounding vehicles and infrastructure is essential. In addition, since HDVs, AVs, and CAVs have different ranges of perceivable information and different response protocols, countermeasures are needed for mixed traffic that occur during the transition period of autonomous driving technology. There is a lack of research on traffic flow optimization that considers the penetration rate of autonomous vehicles and the different characteristics of each road segment. The objective of this study is to develop weights based on safety, operational, and environmental factors for each infrastructure control use case and autonomous vehicle MPR. To develop an integrated evaluation index, infra-guidance AHP and hybrid AHP weights were combined. Based on the results of this study, it can be used to give right of way to each vehicle to optimize mixed traffic.

  • Crowdedness management at subway platforms is essential to improve services, including the prevention of train delays and ensuring passenger safety. Establishing effective crowdedness mitigation measures for platforms requires accurate estimation of the congestion level. There are temporal and spatial constraints since crowdedness on subway platforms is assessed at certain locations every 1-2 years by hand counting. However, smart cards generate real-time big data 24 hours a day and could be used in estimating congestion. This study proposes a model based on data from transit cards to estimate crowdedness dynamically. Crowdedness was defined as demand, which can be translated into passengers dynamically moving along a subway network. The trajectory of an individual passenger can be identified through this model. Passenger flow that concentrates or disperses at a platform is also calculated every minute. Lastly, the platform congestion level is estimated based on effective waiting areas for each platform structure.

  • The use of existing macroscopic research of pedestrian behavior on the walking link as data is limited in determining an individual pedestrian's moving route and the level of service. In macroscopic studies, it is difficult to make quantitative indices, such as pedestrian flow rate, occupied space, density, and speed for determining the level of service on pedestrian roads. Therefore, the microscopic pedestrian route is required to establish appropriate pedestrian policies. In this study, the Yeok-Sam subway station network was examined using a micro-simulation VISSIM, which was then calibrated and validated statistically. The Pedestrian Road's Level of Service of Yeok-Sam subway station area was evaluated using the pedestrian speed as the evaluating index on the Korean highway capacity handbook.

  • Developing countries and small local governments face financial constraints, limiting the adoption of their own bus information systems. However, despite poor social infrastructure and low income levels, developing countries have a high smartphone penetration rate, and the distribution and usage of online content and social media are widespread. Smartphones, equipped with GPS sensors, cameras, and other location-based information collection capabilities, can replace expensive on-site terminals. This study aims to replace expensive on-site terminals with smartphones, develop a center system based on cloud servers, and establish an extensible Open BIS (Bus Information System) service and platform that can be applied anywhere. The goal is to formulate a business model in the process.

  • Recently, there has been a growing interest in user-centered smart city services. In this study, user behavior analysis was performed as a preliminary study for user - centered smart city service planning. In particular, we will use GIS based location analysis data and video ethonography methodology to derive smart city service direction and needs. In this study, the area of Daejeon Design District selected as the Smart City Test bed was selected as the survey area and the location analysis data of the traffic accident analysis system of the road traffic corporation and the fixed camera We observed user's behavior type and change with image data extracted through the technique. Location analysis data is classified according to the type of accident, and image data is classified into 11 subdivided types of user activities. The problems and specificities observed were analyzed. The user behavior characteristics investigated through this study are meaningful to provide a basis for suggesting user - centered smart city services in the future.

  • The location information of the people or mover is essential for supporting various smart mobility services in railway stations which are mostly underground. For this purpose, a smart braille block is proposed to identify the location of the mover of the people. In this paper, the frequency characteristics of each material of the upper and lower parts of the braille block are analyzed to examine the appropriate materials for railway history. In addition, the guidelines for actual manufacturing were derived by analyzing the separation distance between two RF sensors in the smart braille block. As a result of analysis through the characteristic analysis in this paper, after selecting the material suitable for the construction site when the smart braille block is applied, the performance change of the RF system, especially the antenna that greatly influences the RF performance, must be reviewed in advance. It seems to have to be applied after checking through.

  • 스마트카드는 현재 신분확인용 ID 카드, 교통, 신용카드, 위성방송 수신 카드 등 다양한 분야에 응용 되고 있다. 하지만 좀 더 개인의 생활에 밀접한 분야의 응용은 아직 부족한 현실이다. 본 논문은 다양한 분야에서 응용되고 있는 스마트카드를 개인의 신체정보를 이용하여 구입하고자 하는 물품의 구매에 도움을 주고자 하는 취지에서 연구하게 되었다.
