2005년 6월 현재 공식적으로 등록된 시각장애인의 수가 약 18만명에 이르며 2000년 이후 매년 1만명씩 등록 인원이 증가하고 있다. 시각장애인들은 교육, 직업의 선택, 문화의 향유 등에 있어서 소외되어 있으며 생활의 불편을 겪고 있다. 무엇보다도 거리 보행에 있어서 불편함과 위험을 안고 있다. 이를 위해 여러 전자 지팡이 제품들이 소개되어 있으나 고가의 장비여서 대중화에는 한계가 있었다. 본 연구에서는 가격이 저렴하면서도 한국의 보행환경에 적합한 전자지팡이의 개발을 목표로 한다. 이를 위해 1차적으로 시각장애 보행자가 거리를 보행할 때 눈의 역할을 해줄 수 있는 전자지팡이의 기본 설계 및 초음파 센서 실험 내용을 제시 한다.

This study was conducted to develop a Web-GIS based monitoring module of smart city that can effectively respond, manage and improve situation in all stages of illegal dumping management on a city scale. First, five technologies were set for the core technical elements of the module configuration. Five core technical elements are as follows; video screening technology based on motion vector analysis, human behavior detection based on intelligent video analytics technology, mobile app for receiving civil complaints about illegal dumping, illegal dumping risk model and street cleanliness map, Web-GIS based situation monitoring technology. The development contents and results for each set of core technical elements were evaluated. Finally, a Web-GIS based 'illegal dumping monitoring module' was proposed. It is possible to collect and analyze city data at the local government level through operating the proposed module. Based on this, it is able to effectively detect illegal dumpers at relatively low cost and identify the tendency of illegal dumping by systematically managing habitual occurrence areas. In the future, it is expected to be developed in the form of an add-on module of the smart city integration platform operated by local governments to ensure interoperability and scalability.

This study was to evaluate the walking speed of elderly people by using the travel route big data collected by travel diary and smart phone application. We analyzed the change of walking behavior in the residential street environments of the elderly whether they had a company or not. We interpreted the meaning based on previous studies. In addition, the characteristics of elderly people's use of the residential street environment were analyzed by comparing the change in spatial speed according to the companion. The result reveals that the usage patterns of the residential street environments change depending on whether they were accompanied or not. First, the elderly tend to do more social activities while walking alone than when they were accompanied. When they were accompanied the social activities occur in empty lot near the residential area. However, the social activities of the elderly occur in open space such as neighborhood park or playground while walking alone. Finally, This study has strength that it empirically analyzes the elderly's walking behavior and usage paths in small outdoor spaces, including residential streets.

Street trees have been incorporated into urban forests to regulate the microclimate and provide shade as well as provide aesthetic and environmental functions and to evaluate their physiological characteristics. Zelkova serrata is a major tree species that has been planted on various South Korean streets. We determined the physiological characteristics of Z. serrata in street trees of Goyang and Paju in Gyeonggi Province. According to survey sites, net CO₂ assimilation rates was 13.9-16.4 µmol CO₂ m^-2s^-1, chlorophyll fluorescence (Fv/Fm) was 0.80-0.82, and proline contents was showed 3.4-3.7 mg g^-1 FW. The studied trees were assumed to be physiologically stressed, but it was found that Z. serrata was planted as street trees were not significantly stressed when compared to chlorophyll fluorescence responses and proline contents. In the future, the continuous monitoring system is needed to evaluate the physiological characteristics of urban trees.

As inexhaustible clean energy, solar energy will be the most ideal green energy in the 21st century. The effective method to convert solar energy into electrical energy is by solar photovoltaic power generation technologies. LED Emitting Diode is a kind of component which can transform electricity into visible light. As the smart current control system for photovoltaic street lights, the proposed system has improved the battery charging and discharging mechanism to extend the lifespan and effectively controls the LED discharge current according to battery charge state and lighting.

In this paper, remote control and surveillance monitoring system of HID street-lamp using low-cost type of Zigbee communication module was developed. A plurality of capacitors with different capacity are attached to magnetic ballast for HID lamps. Changes in the amount of illumination can be adjusted by the changes in capacity so that the electric energy can be reduced. In Zigbee communication module, a ATmega128L microprocessor is used and in main CPU, ARM9 Core is used to construct a low-cost smart system. In surveillance monitoring systems, the system was configured to remote monitoring of presence of error in the lamp abnormalities, the status of leakage current and abnormalities of ballasts and capacitors and the validity of the proposed empirical experiment was confirmed.

Several efforts to replace the use of existing fossil energy resources have already been made around the world. As a result, a new industry of renewable energy has been created, and efficient energy distribution and storage has been promoted intensively. Among the newly explored renewable energy sources, the most widely used one is solar energy generation, which has a high market potential. An energy storage system (ESS) is a system as required. In this paper, the design and implementation of an ESS for the efficient use of power in stand-alone street lights is presented. In current ESS applied to stand-alone street lights, either 12V~24V DC (from solar power) or 110V~220V AC (from commercial power) is used to recharge power in systems with lithium batteries. In this study, an ESS that can support both solar power and commercial power was designed and implemented; it can also perform emergency recharge of portable devices from solar powered street lights. This system can maximize the scalability of ESSes using lithium batteries with efficient energy conversion, with the advantage of being an eco-friendly technology. In a ripple effect, it can also be applied to smart grids, electric vehicles, and new, renewable storage markets where energy storage technology is required.

This study aims to develop a smart uniform with embedded luminescence for street cleaners to enhance visibility, safety, and long-term usability, informed by real users' opinions. It employed mixed-methods research comprising three phases: first, a pre-interview to identify existing problems; second, experiments to evaluate the visibility and durability of the technology embedded in smart uniforms during machine washing; and third, a post-survey and observation to assess user satisfaction regarding safety, long-term usability, and aesthetic aspects. Prototypes were developed to evaluate long-term usability and safety based on users' opinions. The findings indicated users desired long-term usage without the need for additional wear and highlighted concerns about the glare from light-emitting devices. The developed prototypes demonstrated long-term usability, remaining functional after more than 25 machine washes without reducing brightness or structural integrity. Regarding participant satisfaction, 83.5% of users were satisfied with the design, both aesthetically and functionally. This study offers a viable approach to developing user-centered designs incorporating light-emitting devices, which enhance visibility and provide aesthetic satisfaction while ensuring long-term usability. The results hold significant implications for future design research focused on vulnerable populations, emphasizing integrated satisfaction in terms of safety and long-term usability.

도시의 가로공간이 시민들에게 중요하고 이용하기 좋은 공공공간으로 역할하기 위해서는 가로계획이 단지 도시의 일부를 보행자가 이용하기 편리하고 쾌적함을 줄 수 있도록 계획하는 것에서 끝나는 것이 아니라, 도시전체의 흐름을 이해하고 체계적으로 연계되도록 구성되어야 한다. 본 연구는 시애틀의 블루링 프로젝트를 통하여 이러한 도심 가로구성체계에 대한 구체적 사례분석을 하여 그 물리적 구성방식과 계획적 특징을 분석하였다. 결과 시애틀의 가로체계는 개념적으로 스마트성장개념에 닿아 있으며, 물리적 특징으로 (1)보행자 중심의, (2)다양한 인간활동을 수용하는 오픈스페이스의 일부로서 역할하는, (3)외곽의 오픈스페이스와 연결되어 고립되지 않은, (4)보행자의 흐름이 끊어지지 않고 유기적으로 연계되는 위계적 구성을 가진, (5)지역적 디자인 요소를 최대한 활용한 것으로 분석되었다.
