A questionnaire survey was carried out in order to understand the discomfort when people experience in reading Korean characters of displays. In the survey, 499 respondents (276 males and 223 females), whose ages ranged from 10s to 70s, participated, while 19.6% of the respondents were over 60 years old. The mean visual acuity was 0.93, while it decreased as the age increases from 40s. Approximately 41.4% of the respondents, 98% of them were over 40s, reported that they experienced presbyopia. It was found that the percentage of the respondents who experienced the discomfort much in reading Korean characters significantly increased as the age increases from 40s. The respondents over 40s reported different discomfort experiences according to the type of displays. It was found that the respondents thought that the main reason for the discomfort in reading is related to the character size. The survey results showed that the Korean text in the displays should be designed to be easily readable by the main users.

The research on the factors which effect on legibility is mainly utilized as the basic data of selecting the standard guideline of VDT screen. But the research on Korean is scarcer than that of English. Furthermore, it is unreasonable to apply the results of the foreign language to Korean, beause of the difference between the typography of English and that of Korean. Therefore, more systematic and ergonomic research of the Korean typography on VDT screen is needed. In this paper, an experimental study on search speed and error rate is designed and performed according to different Korean letter size and font on search task with VDT. The experimental screen based on popular Ming and Gothic style is made up of total 12 artificial screens, each 6 different font size. As the criteria of the performance, searching speed(s.s.) and error rate (e) are selected, and CFF value is measured to evaluate user's visual fatigue. The results of experiment in font show that the Korean Gothic style is superior to the Korean Ming style in user's visual performance. The letter size that gives user the optimal performance ranges from the visual angle 39.8' to 55.5' in Ming style, from the visual angle 39.8' to 52.6' in Gothic systle. In visual fatigue experiment, the better performance of letter size is, the less tired user feels. And the smaller letter size is, the more tired user feels. There is no relationship between font and user's visual fatigue.

In this study, we examined the effects of background and underline on the readability of displayed text. The background was placed on every other line and the underline was done with every line of the text. The effect of adding color to the background and underline was also of primary concern. Twenty subjects were tested on their reading efficiency (i.e. time-to-read and comprehension) and subjective preference of different text format presented on a LCD. Result showed that for the background condition, the background with green format significantly decreased the time-to-read as compared to the format without any background. The results of ANOVA on comprehension and subjective preference were also consistent with this finding. For the underline condition, otherwise, the underline with yellow format yielded higher speed and better comprehension. The results imply that adding background or underlines with appropriate colors can be an additional and useful way of improving text readability.

The relationship between users and physical elements of environmental gives a space special characteristics. The Environment Probabilitism by Altman shows that behavior and environment, both response, effect each other construct their characteristics. People can choose their response consciously or unconsciously during their walking , sitting, standing, talking in their environment. Designing a good place can lead people to the goal that they want and designer intend to get, A good place well designed as an positive place is organised with 3 points(1) User's behavior (2) physical elements in environment (3) meanings produced between behavior and physical elements. In this study the importance of physical elements are focused on. In the place where we can have permeability, variety , legibility, robutness, visual appropriateness, richness, personalisation physically , these characteristics will encourage people to have strong motivation and to choose the most active way . From this perspective the circulation of physically handicapped persons is analyzed into their behavioral environment and their behavioral response. The analysis shows the handicapped in our situation has no environmental right for a man itself ,even they have no street to walk safely. And their response to the environment was very negative. Basically the elements from exterior space to interior space should be guaranteed for everyday according to their behavioral characteristics include handicapped. From this study the result shows that the needs of a person should be considered and accepted as an important design problem for improvement our environment.

통계그래픽스는 정량적인 데이터를 이용하여 정보 분석, 추출, 시각화의 과정을 거쳐 정확한 정보전달과 효과적인 이해를 위해 사용자 인지측면에 초점을 둔 디자인 분야이다. 이러한 통제그래픽스에 빅데이터의 구성요소들 내포하게 될 경우 빅데이터 통제그래픽스라고 할 수 있다. 통계그래픽스에서 시각적 요소는 인지부분에 대한 오류를 줄이고 성공적으로 정보를 전달하기 위해 사용되어야 하지만, 빅데이터 통계그래픽스에서는 방대한 데이터로 인해 시각적 요소가 오히려 인지적 방해를 일으키고 있다. 본 연구는 빅데이터 통계 그래픽스에서 나타날 수 있는 인지적 방해요소를 도출하여 제시하는 것을 목적으로 한다. 빅데이터의 통계그래픽스의 유형을 구조적 형태를 바탕으로 '네트워크 유형', '세그먼트 유형', '혼합유형' 세 가지로 분류하였고, 그에 따른 특징들을 탐색하였다. 특히, 빅데이터 통계그래픽스에서 시각적 주요요소를 기반으로 시각화의 고도화 시 나타날 수 있는 인지적 방해요소를 '다차원 범례', '다양한 색채', '정보의 중첩', '서체의 가독성' 네 가지로 도출하여 제시하였다.

The purpose of this study was to analyze the types and meanings of calligraphy presented in modern fashion design. Calligraphy refers to beautiful handwriting or fine penmanship in the West, and handwriting with brushstrokes in the East. The expression patterns being used at present can be divided into three categories. Legible calligraphy is focused on readability more than embellishment. Decorative calligraphy places its importance on decoration at the expense of practicality. The third type, harmonious calligraphy, pursues decorativeness and legibility at the same time. Each of these types of calligraphy is expressed in modern fashion with its own purpose: calligraphy for conveying emotional messages, calligraphy as a special brand image, and calligraphy as an expression of formativeness. The first, calligraphy for conveying emotional messages, is used with characters that are familiar to the public. Calligraphy of this type delivers messages confined emotionally to the conscious world, harmonizing calligraphy with words, or expressing readability filled with purity and delight. Second, calligraphy as a special brand image refers to transmitting a distinctive brand image from other companies through employment of a design motive or pattern by expressing the brand logos or names of designers. Third, calligraphy as a expression of formativeness has the function of shaping expressions as motives or patterns, avoiding meanings of words or phrases. It can be represented by the abbreviation or modification of words, or arranging words in different shapes, harmonizing the words with the clothing construction and atmosphere of the other images.

This study investigated the influential range of landmarks and the relationship between landmarks and cognition factor so as to offer basic data to be used for the effective use and the management of landmarks. In this study, eighteen famous landmark in Seoul were selected and analyzed. The result of this study can be summarized as follows : 1) First, eighteen determining elements of cognition factors were selected via documents survey. Second, general cognition factors of landmarks were analysed using these elements through questionnaires to specialists. As a result of factor analysis, historic cultural factor, scale factor, visual form factor, locational factor and uniqueness factor were revealed. 2) According to revealed cognition factor, eighteen landmarks are categorized into four types using MDS method via questionnaire to resident in Seoul city. These four types of landmarks are: type I that are recognized by historic cultural factor; type II that are recognized by scale factor; type III that are recognized by uniqueness factor; and type IV that are recognized by visual form factor. 3) As the result of regression, the influential range of landmarks were revealed at about a 10km radius(type I : 12km type II : whole area of Seoul city≒15km, typeIII : 8.7km, typeIV : 8.5km). 4) As a result of analysing the correlation between the influential range and the cognition factor through multiple linear regression analysis, the locational factor is the main factor affecting the influential range of landmarks in every type. The uniqueness factor comes next, which affects influential range partially. 5) Except type 1, as a result of analysing the correlation between influential range and the physical heights of landmarks, a quadratic equation is revealed, showing that the influential range of landmarks over 200 meters in height shows a radical change. Landmarks can be used as reinforcement tools of legibility, effective tools for landscape management and for the improvement of a community's image. This study on the influential range of landmarks and main cognition factor can be utilized as a landmark management plan and in urban planning, such as a new town plan.
