As the change in the analog age to the digital age with the development of civilization, people are living in a more friendly smart phone screen more books. In the past, people can easily see the text in the book, and now letters are disappearing from people's minds. And although they can see the letters easily anytime, anywhere using smart devices, they have no interest in the letters, they are interested only in information. So, the letters will disappear. However, there are people who try to keep the development of disappearing letters. In this paper, we are planning to produce a documentary about those people. We show that the letters survive in a modern society through Letterpress print shop, calligraphy, a computer font. And it seeks to inform that the letters are valuable.

This study is to improve the design of bus transfer information that can be substantially used. This study has been processed using the following steps. First, I tried to define the information design and way-finding information design. Secondly, I have researched several case studies, and considered solutions. Finally, I evaluated way-finding maps through pair-wise comparisons, and drew needs through an interview. As the result of this research, there were some problems in font size, improper space between letters and non-consistent information. To solve these problems, the information has to be clear using easy symbols to be well-recognized by citizens. Also, the font size needs to be decided by a calculation of minimum legible size of letters. Lastly, a value contrast between a background color and a letter color needs to be applied more than 70 percent for better visibility. The study is expected to be used as a reference which helps informational design to be developed.

Safety and health related information for the proper use and handling of pesticides is usually printed on the surface of the pesticide products (bottle type or bag type) in the form of texts. But, the guidelines or standards for the appropriate presentation of the texts for the pesticide products are most vague or not practical. Thus, this study aimed to provide the preliminary guidelines for the text sizes based on the legibility experiments. Total twenty subjects from two age groups (young: n=10, old: n=10, five males and five females in each group) participated in the experiment. First, subjects read the text cards presented in the distance of 50cm from the eyes of the subjects. Eight different text card sets were prepared for different font type(thick gothic-type and fine gothic-type), thickness of font(plain and bold), and number of syllables (2 and 3 syllables). When subjects read the cards, the correctness of reading (correct or wrong) was recorded and the degree of discomfort (from 1: no discomfort at all to 4: can't read at all) was also evaluated for all the text sizes. Results showed that the character size should be 4 pt or larger for the young subjects to read at least one word correctly in all the text conditions. For the old subjects to read at least one word correctly, the character size should be five pt or larder. The average of the minimum character sizes for 100% correct answer is 6.1 pt for young subjects and 10.5 pt for old subjects, respectively.

BACKGROUND/OBJECTIVES: The objective of this study was to investigate food allergens and prevalence rates of food allergies, followed by comparison of consumer attitudes and preferences regarding food allergy labeling by diagnosis of food allergies. SUBJECTS/METHODS: A total of 543 individuals living in Seoul and Gyeonggi area participated in the survey from October 15 to 22 in 2013. RESULTS: The results show that the prevalence of doctor-diagnosed food allergies was 17.5%, whereas 6.4% of respondents self-reported food allergies. The most common allergens of doctor-diagnosed and self-reported food allergy respondents were peaches (30.3%) and eggs (33.3%), respectively, followed by peanuts, cow's milk, and crab. Regarding consumer attitudes toward food labeling, checking food allergens as an item was only significantly different between allergic and non-allergic respondents among all five items (P < 0.001). All respondents reported that all six items (bold font, font color, box frame, warning statement, front label, and addition of potential allergens) were necessary for an improved food allergen labeling system. PLSR analysis determined that the doctor-diagnosed group and checking of food allergens were positively correlated, whereas the non-allergy group was more concerned with checking product brands. CONCLUSIONS: An effective food labeling system is very important for health protection of allergic consumers. Additionally, government agencies must develop policies regarding prevalence of food allergies in Korea. Based on this information, the food industry and government agencies should provide clear and accurate food labeling practices for consumers.

Seal is a tool to prove an individual or group. Guk-Sae and Eo-Bo uses typeface to represent their names or titles, which change from tensile to tensile and have varied from time to time. Although the Korean alphabet currently uses Hangul, it had used Chinese characters before Hun-Min-Jeong-Um was created in 1443. All seals and royal seal before the Korean Seal of State were made in Chinese characters. This thesis analyzes the concept of typography through the royal seal, and the subject of this study is 'Sugang Emperor' which is the only eight-letter version seal of the Joseon Dynasty's various royal seal. Bo-Yeong, which is shown in Bo-Myeon has artistic value with beautiful typeface and proportions, which is worth research. It examines the features of the Korean seal, analyzes and studies the typeface shape and features from the typographic perspective of the "Sugang Emperor Bo-Yeong," or writing.

Fonts are digitized into a file and recognized as a intellectual property by the revision of the design protection act in 2005. Fonts are passed on to the users and are developed into design products. In this study, we have developed a model of font usage system as a design product based on Ahn Se Yoon's brand value system model. Based on the usage system model of the typeface, the lifecycle as a design product of the typeface was defined and analyzed as four different phases (introduction, growth, maturity, and decline.) In this study, To investigate the lifecycle of fonts, we selected the Gulim-chae which is most widely used as digital font files in Korea and are now in decline phase. Through this study, We hope that it will be useful for developing fonts, licensing system, and establishing brand strategies.

In this paper, a new algorithm for extracting and recognizing characters from video, without pre-knowledge such as font, color, size of character, is proposed. To improve the recognition rate for videos with complex background at low resolution, continuous frames with identical text region are automatically detected to compose an average frame. Using boundary pixels of a text region as seeds, we apply region filling to remove background from the character Then color clustering is applied to remove remaining backgrounds according to the verification of region filling process. Features such as white run and zero-one transition from the center, are extracted from unknown characters. These feature are compared with a pre-composed character feature set to recognize the characters.

본 논문에서는 문서 위의 문자를 Off-Line방식으로 컴퓨터에 저장할 수 있도록 기하학적 패턴 벡터를 이용하여 한·영문자 및 글꼴을 인식하는 알고리즘을 제안하였다. 일반적으로 문서에서는 여러 가지 글꼴에 따라 글자의 형태가 다르므로 대표적인 한·영 세 가지 글꼴을 기하학적 패턴(Geometrical Pattern Vector)을 이용하여 크기와 이동에 인식하도록 하였다. 이진 입력 한영혼용 영상에서 잡음을 제거하고 수평·수직 투영 기법을 이용하여 한 문자를 분할하여 문자의 폭에 따라 기하학적 패턴을 추출한다. 추출한 패턴은 각 합계를 계산하여 기준 패턴 합계와 비교한 후 기준 패턴 문자와 글꼴을 인식하게 된다. 마지막으로 제안한 알고리즘의 성능을 평가하기 위해 크기, 이동 변형이 있는 대표적인 한·영 글꼴(신명조, 궁서, 고딕)체와 영어 Time New Roman체를 대상으로 모의 실험을 수행하였다. 제안한 알고리즘은 기존의 원형 패턴 알고리즘보다 문자인식률과 글꼴 그리고 영어의 대·소문자를 구별하는 우수함을 보였다.

본 논문에서는 글꼴의 변화와 잡영을 흡수할 수 있도록 자소의 탐색 영역을 정의 하였으며 이 영역에 나타나는 횡모음과 종모음의 주획을 추출하는 방법을 기술하였다. 종모음 영역에서 추출한 수직획들과 횡모음 영역에서 추출한 수평획들을 각각 종모음과 횡모음의 주획이 될 수 있는 후보들로써 이들로 부터 종모음과 횡모음의 존재를 파악하는 것이 한글 유형 분류의 주된 내용이다. 그러나 다양한 글꼴에 나타나는 수평획들로부터 곧바로 횡모음의 존재를 파악하는 것은 쉬운 문제가 아니다 본 논문에서는 기존의 트리 분류기를 확장하여 복잡하고 다양한 특징을 단계별로 단순화시키고 트리 분류기의 상위 노드에서 결정된 정보와 제약 조건을 이용하여 유형을 분류하는 방법을 제안하였다. 제안된 방법은 한글 상위 빈도 1405자, 3가지 글꼴에 대하여 99.8 %의 유형 분류율을 보이고 있다.

In this study, smart laser pointer using image processing was studied. The laser pointer tracked the light by using image processing. and the tracking signal was received to the transmitting unit. Smart laser pointer received the video signal have function of erase, write convert window, and changing of font color. It was studied that the smart laser pointer system could run pointer and mouse function on the one place.
