This study aimed to investigate the language usage of outdoor advertisements and find ways to improve it from the perspective of public language. Anyone is exposed to signboards without limitations, and it allows the public to learn fixed language forms for a long time. Therefore, it has both direct and indirect effects on the public’s language lives. This study focuses on sign language as a public language. Here, signboards from four districts in Gyeonggi-do were collected and analyzed in three ways. Signboards marked only in Korean accounted for a relatively large proportion of the main words, whereas mixed types of characters were used together in the subwords. In addition, there were cases of intentional violation of the language norm and listed only the initial consonants, those conscious of ambiguity. Results show that follow-up studies, such as conducting an additional survey, designating a demonstration area for the practical maintenance of sign language, and preparing guidelines for the production of outdoor advertisements, are expected to continue.

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.

Indiscriminately installed signboards are messy in out of harmony with the urban environment. In such a case, improving signage project is needed to improve significantly the urban environment. Signboards are installed to give good perceptional effect through communication with the customer. Also, Signboards are designed to make harmonize well with the urban environment because signboards are installed in virtually every place, such as the residential environment, the natural environment, the commercial environment of the city. The design of signboards should consider functional elements as a perceptual media and the user interface communication in order to provide customers with various services such as traffic information and life safety. In this study, we analysis design and functionality the customer is seeking, and suggest design elements of signboards which can well harmonized with the urban environment.

본 연구에서는 강풍 위험 모델과 강풍 취약도 모델을 개발하여 옥외 광고물의 강풍 위험도를 정량적으로 평가하였다. 강풍 위험 모델과 강풍 취약도 모델 모두 확률론적 접근법인 몬테카를로 모사 모형을 적용하여 개발되었으며, 강풍 위험도 모델은 평가된 강풍 위험과 강풍 취약도의 수학적 계산을 통해서 평가되었다. 강풍 위험은 국내 내륙과 해안지역의 대도시인 서울과 부산 지역에 대하여 평가되었으며, 강풍 취약도 모델은 현장 조사와 문헌 조사를 통하여 파악된 10종의 벽면 이용형, 8종의 돌출형 옥외 광고물을 대상으로 개발되었다. 강풍 위험도에 영향을 미치는 요인을 파악하기 위하여 지표조도구분, 옥외 광고물의 형태, 설치 지역, 설치 높이 등에 따른 강풍 위험도를 정량적으로 평가하였다. 본 연구에서 제안한 강풍 위험도 평가 방법은 강풍으로 인한 옥외 광고물의 손실 추정 및 피해 저감 대책 수립을 위하여 활용될 수 있을 것으로 판단된다.

최근 강풍으로 인한 옥외광고물의 파손 및 추락으로 인해 불특정 다수에게 인적 및 물적 피해를 야기하고 있다. 옥외광고물은 사유시설과 공공시설물의 성격을 모두 갖기 때문에 옥외광물로 인한 피해를 저감하는 것은 개인의 노력뿐 아니라 제도 및 규정을 통해서도 이루어져야한다. 이러한 피해는 강풍에 취약한 옥외광고물의 내풍설계 기준의 미비가 가장 큰 요인으로 인식되고 있어 본 연구에서는 옥외광고물의 내풍설계 표준을 제시하였다. 이를 위해 풍속에 영향을 주는 옥외광고물 설치위치의 주변 풍환경이나 높이, 설치위치 등 풍속과 관련한 요소를 반영하였으며, 건축구조기준 2015(안)의 기본풍속도와 풍속보정 절차에 의한 풍하중 산정 과정을 제시하였다. 이 과정에서 공학적 판단이 요구되는 옥외광고물 설치위치 주변의 지표조도구분 및 지형계수 평가에 대해 정략적으로 적용할 수 있는 기준을 제시하였다. 또한 비전문가 관점에서 적용하기 용이하도록 가능한 단순화된 정량화 절차를 제시하였다.

Advertisement signboards on the buildings have functionally a visual value as factor of urban and building design. But it is not easy to find any reasonable principles and regulations, how well the signboards deliver the information of stores to the customers, and how they contribute the visual amenity from the sight of urban landscape. Under this context, this study tries to analyze the information delivery power of signboards in relation to the visual cognition. The analysis method is the Two-Way ANOVA (Analysis of Variance) evaluation with factors, such as scale, amount and arrangement of signboards. The scale of letters or figures at Signboards is specified in 3 different sizes such as big, medium and small. The amount is classified into 5 grades from 100% to 20% installation. And the arrangement is divided into orderly and disorderly installation. As the results of the Two-Way ANOVA, the identical scale of signboards is much better for the awareness. And the orderly arrangement shows also the same result. Above all, including these two results, the 80% of installation showed the biggest different result of awareness.
