In this paper, we propose a correction method using phoneme unit segmentation to solve misrecognition of Korean Texts in signboard images using weighted Disassemble Levenshtein Distance. The proposed method calculates distances of recognized texts which are segmented into phoneme units and detects the best matched texts from signboard text database. For verifying the efficiency of the proposed method, a database dictionary is built using 1.3 million words of nationwide signboard through removing duplicated words. We compared the proposed method to Levenshtein Distance and Disassemble Levenshtein Distance which are common representative text string comparison algorithms. As a result, the proposed method based on weighted Disassemble Levenshtein Distance represents an improvement in recognition rates 29.85% and 6% on average compared to that of conventional methods, respectively.

Unlike other types of outdoor advertisements, rooftop signboards are installed on the roofs of buildings, rather than on their outer walls. This means that the area of a rooftop signboard is commonly larger than that of a general outdoor signboard. Moreover, as such signboards are greatly influenced by the wind, they can suffer a lot of damage from typhoons and strong winds every year. However, there is no wind load specification for rooftop signboards. In this study, wind pressure experiments were conducted to investigate the peak wind pressure on each side of rooftop signboards installed on the roofs of 5-15 story buildings in a city center. The minimum peak wind pressure coefficient was -3.0 at the bottom edges of the front and back of the rooftop signboards and -2.0 along the entire length of the sides. As the height of the rooftop signboard increased with the increasing height of the buildings, the peak value was found to be larger than the absolute peak value for the minimum peak wind pressure coefficient. The maximum and minimum peak wind pressure distributions of the rooftop outdoor signboards were influenced by the position of the signboard and the wind angle.

Indium tin oxide(ITO) thin films were deposited on the glass substrates by radio-frequency (RF) magnetron sputtering method. The influence of rapid thermal annealing (RTA) treatment on the optical and electrical properties of the films were investigated for the purpose of fabricating plasma display signboard. Structural properties, surface roughness, sheet resistance and transmittance of the ITO film were analysed by using x-ray diffraction method, atomic force microscopy (AFM), four point prove, and ultraviolet-visible spectrometer, respectively. It was found that the RTA treatment increased the transmittance and decreased the resistivity of the ITO film, respectively. Furthermore, we successfully demonstrated the direct-current plasma signboard by using ITO electrode and phosphors.

This study examined the effect of store fit perceived by consumers for improved signboards on visit intention to store, and the mediating effect of informativeness, entertainment, and irritation. The survey was conducted from November 7 to November 18, 2022 with 150 undergraduate and graduate students who had experience visiting areas where signboard improvement projects were implemented. The collected data were analyzed using SPSS 26.0 and PROCESS Macro 4.2. The results showed that store fit had a positive effect on visit intention to store by mediating informativeness and entertainment. This results suggest that practitioners of local governments and government agencies and store owners should consider store fit of signboards as important when participating in signboard improvement projects.

The street image in a business area is so much affected by Facade that the front side of a roadside building makes. Recently, for the indiscreet and intemperate advertising signboard of the front side of roadside buildings, a streetscape becomes more disordered than before, so now we need to do research about signboards of roadside buildings for a streetscape image. In this research, we focused on a streetscape with difference of occupation density of signboard in the business area via investigation and analysis about occupation density of signboards of the front side of roadside buildings, and we suggested optimum occupation density of signboards for supporting the road image positively. An object of research is the street in the business area that has many pedestrians and active passing zone of cars. We investigated and analyzed how to feel street images on the rate of occupation density of roadside building's signboards of in the chosen street. As a result of using an adjective that we use for estimating street view images for extraction of street images, we could know 2 factors. We named that one is the image of recognition, and the other is the image of feelings. We knew that signboard density of street of heavily recognized images is from 20% to 30% and, signboard density of street of heavily feeling images is from 50% to 60%. We also could know that people feel both images of recognition and images of feeling in specific density, 30 to 50%. Through this result of research, we can suggest Facade on signboard density with the recognition and the feeling and use images of the street view as materials to be more specific and more special.

Previously, in order to send information from the local controller to the display board, the hardware or software had to be handled and run through 3-phases, which include the PC-card or PC-add Board, I-F card and Sub board. This study will attempt to design a board that handles information by connecting the USB port of the PC directly to the Sub board. In addition, an MPU will be attached to the previously complex hardware circuit to design a software drive engine module, which allows for the development of new products by modifying only the software engine and not the hardware.

In this study, we focused on the low practicality of traditional outdoor advertisements due to uniformity of materials, shapes, and designs, so in order to improve it, we will analyze impact on the practicality of outdoor advertisements depends on the attached type of advertising signboards. The research method is to set up a research model and hypotheses through a literature review and conduct a survey and then perform factor analysis and hierarchical regression analysis. Hypothesis1. The evaluation factors (readability, formability or symbolism) of outdoor advertising signboard in traditional markets will affect their practicality. Hypothesis 2. The type of attached advertising signboards (protruding type or wall-type) in traditional markets will control the impact of each evaluation factors' on practicality. In a result, readability and formability will affect practicality. To increase practicality, the size, color, font, layout and etc. of outdoor advertising signboards should be well recognized to get the better understanding. Also, practicality will be increased by the harmonization and the sense of balance.

Recently, City has contributed to the various and convenient environment by public design projects. These projects have grown very attentive to the outdoor signboards in cities. From this background, the local governments including the central government have driven to the outdoor signboards through the city street scenery improvement projects. These the outdoor signboards improvement projects are strengthen the city's aesthetic function and city street scenery. In this research, we surveyed the satisfaction level of the outdoor signboards for shop which were engaged in this project and citizen by t-test method. We surveyed 30 stores and 41 citizen for the outdoor signboard's aesthetic function, a reflection of region and store's properties and communication effects. From our results, we researched the various understanding and satisfaction of the outdoor signboards improvement projects. Stores owner and citizens did not satisfy the outdoor signboards improvement projects. From our research, in order to advertise the city's aesthetic function and to create our own unique outdoor signboards culture, a variety of tools and intensive cases are demanded, in the future the research on the outdoor signboards improvement projects must revitalized.
