Recently, despite the presence of a large number of people with disabilities, facilities and services for the disabled are insufficient in comparison with the advanced countries. Especially, unmanned facilities and devices are not available for disabled people without help. As interest in disabled people increased, the convenient facilities for the disabled person should be legally installed in the public places. Moreover, social consensus formation and technical approaches are being actively pursued. In this paper, we propose a five-step scenario to use an unmanned post office. Based on the proposed scenario, we present the method to improve the accessibility of the user interface of the unmanned facilities. And we present a plan for establishing the short- and medium-term service models. This plan is expected to be highly practicable because it reflects the current situations of Korea Post and analysis result of the domestic and oversea cases.

The existing Von Neumann architecture places limits to data processing in AI, a booming technology. To address this issue, research is being conducted on computing architectures and artificial neural networks that simulate neurons and synapses, which are the hardware of the human brain. With high-speed, high-throughput data communication infrastructures, photonic solutions today are a mature industrial reality. In particular, due to the recent outstanding achievements of artificial neural networks, there is considerable interest in improving their speed and energy efficiency by exploiting photonic-based neuromorphic hardware instead of electronic-based hardware. This paper covers recent photonic neuromorphic studies and a classification of existing solutions (categorized into multilayer perceptrons, convolutional neural networks, spiking neural networks, and reservoir computing).

Among the community-based cultural facilities, public libraries are places for social and educational purpose that improve the education of the resident, the expansion of the basic cultural education, communication between the members of society, and the accumulations and preservations of the culture. Public libraries should be a local cultural facility that expresses the value of a community. This study aims to analyze the design expression of publicness in a public branch library as a community-based cultural space through the study of branch library in the U.S. This study focused on the most future-oriented and innovative Ten New Landmark Libraries in the United States selected by Library Journal magazine in 2011. Among the selected libraries, three branch libraries which belongs Arizona Maricopa County were included in the study. The results of this study are as follows. First, the sites of the branch libraries vary geographically, but the libraries increase accessibility are caused by unique appearances and design concept of intellectual interest. Second, the floor plan shows the separation of meeting rooms and faculty space from the public space and has visual and spatial open space by high ceiling of the reading room. Third, multi-functional public space for residents are meeting rooms, the external patios for reading, galleries, cafes, libraries-shops which provides a variety of cultural programs, activities, and the opportunity to socialize neighbors. Fourth, branch Libraries have unique designs that harmonizes with nearby places to reflect locality, giving the locals a sense of pride in their community. Fifth, concrete brick and metal panel were used as finishing material for the practicality of maintenance. In particular, transparent glass envelope allows the locals to stay for long time due to openness and brightness of space.

As the public interest in environmental issues increased, the "Act On The Integrated Control Of Pollutant-Discharging Facility" was enacted. Through the integrated environmental pollution prevention act in which 19 industries with large environmental impacts are sequentially applied, pollutants can be managed in a medium-integrated manner and integrated permission of the business unit is possible and BAT can be applied to enable a scientific and proactive environmental management system. In order to facilitate the implementation of integrated environmental pollution prevention act with these advantages, the BAT BREF should be published, modified and revised every 5 years considering the level of scientific development. This study reviewed the issues to be considered in applying BAT and the types of BAT and focused on presenting improvements and development direction when revising and supplementing the standards in the future based on these contents. For this purpose, when revising the standards, it will be necessary to reflect on the domestic situation, to expand the TWG(Technical Working Group) of small-scale workplace experts, and to exchange opinions with business places that have similar processes for each waste type through a systematic total inspection. In addition to these methods, by establishing a resident participation system through information disclosure, it is expected to be used as a guideline for environmental management of business places not subject to integrated permission of less than 3 types as well as those subject to integrated permission.

Since users who search maps conduct their searching using the name they already know or is commonly called rather than formal name of a specific place, they tend to fail to find their destination. In addition, in typical web map service in terms of spatial searching of map. Location information of unintended place can be provided because when spatial searching is conducted with the vocabulary 'nearby' and 'in the vicinity', location exceeding 2 km from the current location is searched altogether as well. In this research, spatial range that human can perceive is calculated by extracting POI date with the usage of twitter data of SNS, constructing spatial relations with existing POI, which is already constructed. As a result, various place names acquired could be utilized as different names of existing POI data and it is expected that new POI data would contribute to select places for constructing POI data by utilizing to recognize places having lots of POI variation. Besides, we also expect efficient spatial searching be conducted using diverse spatial vocabulary which can be used in spatial searching and spatial range that human can perceive.

Recently, as users' interest for travel increases, research on a travel route recommendation service that replaces the cumbersome task of planning a travel itinerary with automatic scheduling has been actively conducted. The most important and common goal of the itinerary recommendations is to provide the shortest route including popular tour spots near the travel destination. A number of existing studies focused on providing personalized travel schedules, where there was a problem that a survey was required when there were no travel route histories or SNS reviews of users. In addition, implementation issues that need to be considered when calculating the shortest path were not clearly pointed out. Regarding this, this paper presents a quantified method to find out popular tourist destinations using social big data, and discusses problems that may occur when applying the shortest path algorithm and a heuristic algorithm to solve it. To verify the proposed method, 63,000 places information was collected from the Gyeongnam province and big data analysis was performed for the places, and it was confirmed through experiments that the proposed heuristic scheduling algorithm can provide a timely response over the real data.

Robot performances in public places are conducted for the purpose of promoting robot technology and inducing interest in events, exhibitions, and streets instead of dedicated stages. This paper extracts robot images in real time from a robot operation in front of a green chroma key cloth, and synthesizes them on various stage images. A simple and robust method for extracting a foreground robot from a chroma key background without a user's preset is proposed. After increasing the color difference between the background and the foreground, this method automatically removes the background based on the histogram of the difference information, thereby eliminating the need for a user's preset. The simulation shows 98.8% of foreground extraction rate and experimental results demonstrate that the robots can effectively be extracted from the background.
