Characteristics of handwriting were investigated and compared between the patients with writing disabilities and normal elementary school pupils. Generally, the heights of the letters of the patients were significantly larger than those of normal children, and letters of the patients were more sparsely distributed than those of controls. The distance between the words were significantly reduced in the patients’ writings, which indicated that patients had much more problems of space-leaving than normal pupils. Letter heights differences were significant across all grades in the patients and normal controls. The heights of the letters decreased as they grew older, and the slope of the decrements were more steeper in normal girls(r=-0.45) than girls with writing disabilities(r=-0.16). Sex differences were found in the letter spacings in low grades(grades 1, 2), that is, the distances between the letters were significantly narrower in the male patients than normal boys in these grades, and the differences were almost indiscriminating in grades 3 through 5, and finally, in sixth grade, letter spacings were signifycantly broader in normal boys than male dysgraphics. In girls, letter spacings were significantly broader in the patients across all grades. These findings supports the hypothesis that male and female writings were qualitatively different and that distinct mechanisms served in boys and girls dysgraphics. Across all grades and sexes, spaces between the words of the patients were significantly broader than normal pupils, which suggested that space-leaving between the words was important in Korean writings. There was trend that letter spacings and word spacings decreased across grades, but in girls, no correlations between the letter spacings and grades were found. Correlation analyses revealed that letter heights and letter spacings had mild correlation(r=0.11-0.15), and that letter spacings and word spacings had robust correlation(r=0.99). Phonological errors were mostly found in last phoneme(Jong-seong), especially double-phoneme(ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄾ, ㄿ, ㅀ, ㅄ), and in the case the sound values changed due to assimilations of phonemes. Semantic errors were rare in both groups. Space-leaving errors were correlated with phonological errors, and more frequent in boys than girls. In conclusion, significant differences existed in the letter heights, letter spacings, word spacings, and frequencies of phonological errors and spaceleaving errors between the patients with writing disabilities and normal pupils. The characteristics of writings changed across grades and the developmental profiles were somewhat quantitatively different between the groups. The differences became obvious from the second-third grades.

Digital signage takes the role of promotion, providing information, art and game as it is installed in various forms everywhere such as the road, subway and indoor space we pass through. The related researches also focus on the technology of realizing digital signage, current industrial state and prospect in most cases. On the contrary, the researches on the spaciality of digital signage is a kind of insufficient, this study was carried out based on the judgment that there is necessity of researching it in respect that the recognition of space by the people in there is different before and after digital signage is located in such space. First, in order to understand digital signage, its concept, type and kind were investigated, general theories about the spaciality were considered after that, the spaciality of digital signage was grasped by 5 factors such as hybridity, vitality, mobility, flexibility, and contingency and their characteristics were offered in this study. In its conclusion, it was appealed that the change of spatial recognition along media and continuous research are required as digital signage is the transactive space.

In the airport, digital signage is used to provide the flight-related information for the passengers. Because the current digital signage is based on wired networking or storage medium, its use is limited in terms of the location and the usage of the digital signage. In order to overcome these limitation, we present a WiBro-based digital signage for the wireless broadband networking and the mobility of the digital signage. We perform comparative experiments with the WiBro-based digital signage and WLAN-based digital signage under various locations, datarate, advertisement contents. The experimental results showed that the WiBro-based digital signage is preferred when the mobility is required, while the WLAN-based digital signage has advantage in datarate.

본 논문에서는 디지털 사이니지와 스마트폰간의 양방향 광고 및 정보 전송이 가능한 차세대 광고 모델을 제안한다. 디지털 사이니지는 옥외라는 공간의 특성상 지나가는 사람들에게 짧은 시간 동안 주목을 유도해 광고를 노출시켜야 하고 설명형 광고 표출이 어려운 공간적인 한계를 가지고 있다. 반면 스마트폰은 사용자들과 물리적으로나 심리적 거리상으로 가장 밀접한 위치에 있고 언제 어디서나 무선인터넷과 애플리케이션을 활용할 수 있어 광고효과가 뛰어난 매체이다. 따라서 디지털 사이지니 앞을 지나가며 관심있는 정보나 광고를 스마트폰으로 전송 받고 원하는 시간과 장소에서 스마트폰으로 본다면 디지털 사이지니 광고매체의 공간적 한계를 극복하고 광고효과를 높일 수 있을 것이다. 본 논문에서는 이러한 디지털 사이니지를 활용한 개인형 모바일 광고에 대한 요구사항을 도출하였고, 향후 실제 시스템을 구축할 계획이다.

'The Three Bonds And The Morals in Human Relations' was published in Joseon Dynasty period in 1434, relatively early days of comic history in the world. The gaps between comics frames have symbolic meaning as comics frames have in the area of symbols of comics. After comics frames appeared, it was likely that the advent of the gaps between frames had its own value in the aspect of comics history. Historical backgrounds of domestic comics would be built on firm base led by studying on the symbolic meaning of the gaps between comics frames. Two forms of the gaps between frames were shown in 'The Three Bonds And The Morals in Human Relations.' The first form is the gap between cloud frames. The second is the gap between cloud frame and background frame. Although a little difference is found in the shape and display, two forms of the gaps between frames in 'The Three Bonds And The Morals in Human Relations' have a similarity to modern comics. This study is to demonstrate valid background for the domestic history of comics by means of analyzing the shapes of the gap between comics frames in 'The Three Bonds And The Morals in Human Relations.' The objective of this study is to prove the meaning of the shapes of the gaps between comics frames 'The Three Bonds And The Morals in Human Relations', focusing the gaps between frames among symbols of comics.

This study started by examining 24 newly-built elementary schools in Sejong City with regard to their present conditions of in-between space. After categorizing the space according to its spatial composition, 5 schools were selected and analyzed in relation to the current status and frequency of use of their in-between space. Among the (other schools, the analysis gave the following results: 1) There was much higher usage of the in-between space for rest/play than for learning, which suggested that more rest/play area and apparatus should be provided. 2) Piloti areas were preferred, and a greater number of activities took place in these places than in the adjoining open areas. 3) When the in-between space was combined with a passage (as in the case of E2 and E3), a separation must be provided in order not to interfere with the rest/play activities. 4) In planning the in-between space, priority should be given to activities over landscape purposes. 5) Diverse and easy access to the space must be planned, particularly as the main entrance is not directly connected to the space. Entry at the end of an adjacent building could be a possible solution.

The purpose of this study is to conduct an exploratory investigation into Korean psychopathy by synthesizing the results of prior domestic research on the validation of psychopathy assessment tools. Domestic research on the validation of psychopathy scales has been constrained by limited research methodologies, bias toward male subjects, and the application of inappropriate factor structures. Furthermore, although discrepancies between the original scale and the Korean scale were identified regarding the factor structures through in construct validity research, discussion on the concept of Korean psychopathy has been limited. As a result, this study compared 16 domestic papers on the validation of psychopathy assessment tools along with 9 international foreign papers that addressed the factor structure of each original scale. By comparing the derived factor structures, items assigned to each factor, and omitted items from each study, the characteristics of Korean psychopathy were explored. The findings revealed that Korean psychopathy is recognizable from materialism, machiavellianism, and antisocial behavior and impulsivity. This study holds significance in synthesizing the outcomes of current domestic psychopathy validation research and offers a conceptual foundation to help understand Korean psychopathy.
