본 논문에서는 제한된 필기 글꼴을 이용한 휴대형 정보기기용 온라인 문자 인식 알고리즘을 제안하였다. 한글과 영숫자를 동시에 사용하는 문자 인식은 애매성으로 인하여 인식율이 낮아지며, 이를 극복하기 위하여 모드 변환이나 영역 분리 등의 제약을 하게 된다. 본 논문에서 제안한 인식 알고리즘은 한글과 영문자, 숫자를 혼용하여 사용할 수밖에 없는 우리의 문자 환경에서 사용자의 평의성을 최대한 살려 입력 모드 전환이나 필기 영역 분리 등의 제약을 하지 않는 단일 알고리즘이다. 또한 역추적에 의하여 인식 과정에서 발생할 수 있는 미의식 또는 오인식을 보정할 수 있도록 한다. 제안한 알고리즘은 전체 알고리즘의 크기가 작으며 계산량이 적어서 메모리와 속도 등의 성능에 있어서 자원의 제약을 가질 수밖에 없는 초소형 휴대형 정보기기의 입력 장치로서 적합하도록 연구하였다. 실험 결과 영숫자 98%, 한글 97%의 인식율을 얻어 유용성을 확인하였다.

The purpose of this study is to understand the important factor of internet travel product purchase according to the characteristics of SNS tourism information. The characteristics of SNS tourism information perceived by travel product consumers are investigated as four major dimensions; reliability, interest, interaction, and usefulness. 17 items of online travel product purchase are adopted and produced four factors namely; safety, price & cost, customer service and convenience. We confirm that consumer have high importance on reliability consider convenience as most important factor of online travel product purchase. Interest of SNS tourism information have significant relation with price & cost, and Usefulness and Interaction of SNS tourism information have significant relation with customer service of online travel product purchase.

Despite the continuous development and provisions of state public library standards there has been little research about how useful they are for what aspects of public library activities The purposes of the present study are 1) to understand, from the directors points of view the utility of state standards for planning and evaluation: and 2) to explore the types of factors, related to the directors' backgrounds and/or the library planning and evaluation contexts associated with the directors perceptions. Through a self-administered mail questionnaire, 1,198 public library directors in Kansas Texas and Wisconsin were surveyed. and 737 directors replied ($61.5\%$ response rate). The directors perceived the standards useful for both planning and evaluation. Public library directors viewed the collection and service standards as more useful than administration, staffing and facilities standards. Library size and community involvement were associated with the directors perceptions, yet the directors professional background, was not significantly related to his or her perceptions. The findings suggest that public library directors perceptions of the utility of state standards need to be understood within the library condition and Its community context. and the emphasis on community based public library planning and evaluation should continue to be employed in the standards.

This study investigated how people perceived the importance of health message design principles including gist presentation, usefulness of content, format, and intuitive design and how well a webzine article published by Korean Ministry of Food and Drug Safety was designed in terms of the four design principles. This study also explored what individual characteristics influenced the perceptions of health message design principles. A total of 294 adults participated in the survey, and their responses were analyzed with the Importance-Performance Analysis method. Participants perceived that usefulness of content was most important in the text design; gist presentation was most important in the visual design; and format was well designed in both text and visual messages. This study showed that it is crucial to improve the quality of visual health messages particularly in terms of gist presentation and intuitive design. We also found that individuals' interest in health played a significant role in the perceptions of health messages. These results were discussed in regards to principles and strategies for the effective design of health messages.

This study was performed to figure out the effects of perceived usefulness and ease of use in Technology Acceptance Model(TAM) affecting acceptance attitude and intention to use in smart learning. In addition, the study recognized the need for differentiation of learning time by analyzing the difference of effects influencing acceptance attitude of perceived usefulness and ease of use during learning time, which is at the beginning, midterm, and at the end of the term. As the results of the study, it showed that there were differences between the factors, the learning time of which was considered, affecting acceptance attitude and intention to use. Furthermore, in order to improve the effectiveness of building a smart campus, which is currently under the construction, the study argued that universities need to consider the learning relevance and subjective norm as important factors in perceived usefulness of smart learning. Finally, the need for the design of various smart learning types became accepted considering learning time.

This paper studied the relationship between the quality of perceived service and the consumer satisfaction on IPTV which is on the increase in the number of subscribers as the representative of a convergence service of the communication and broadcasting. Using the measurement tools of five factors such as the perceived service quality, the accommodation of information techniques, the consumer satisfaction, the intention of continuous use and the users' intention to recommend to others, the empirical study on IPTV users was taken. The results showed that the perceived serviced service quality, usefulness and easy access to IPTV have strong effects on the use and the users, intention to recommend to others.

This study presents an ultrasonic location awareness system for the ubiquitous computing with absolute position. The flight time of ultrasonic waves is determined by a period detecting technique which is able to extend the sensing range compared with traditional methods. For location awareness, ultrasonic waves are sent successively from each ultrasonic transmitter and synchronized by radio frequency (RF) signal, where the transmitting part is fixed and the receiving part is movable. To expand the recognizing range, cell matching technique and coded ultrasonic technique are introduced. The experimentation for various distances is accomplished to verify the used period detecting technique of U-SAT system. The positioning accuracy by using cell matching is also verified by finding the locations of settled points and the usability of coded ultrasonic technique is verified. As a result, the possibility of ultrasonic location awareness system for the ubiquitous computing can be discussed as a pseudo-satellite system with low cost, a high update rate, and relatively high precision, in the places where GPS is not available.

The purpose of study is to enhance the convergence effects of cyber lecture for university students. The results were derived through the comparison and verification of recognition levels before and after cyber lectures. The study material was a questionnaire composed of 15 questions divided into five areas; usefulness, enjoyment, academic relevance, social intention and usage intention. The recognition levels significantly improved after learning in five areas with particularly large improvements in enjoyment and academic relevance. The recognition levels significantly improved in the five areas(p<.001). With regard to changes in recognition levels by major, social science majors showed significant improvements in usage intentions after learning. Cyber lectures for university students were proved to be generally convergence effective.

This study aimed to determine factors affecting attitudes and digital literacy toward online learning of nurses. A cross-sectional study was conducted from 190 nurses working in hospitals. The factors influencing the online learning attitude were gender, working hospital size, and perceptions of internet usefulness and importance, and the factors influencing digital literacy were age, working position, perceptions of internet usefulness and importance, and attitudes toward online learning. Online learning and educational development of nursing could be explained in the context of rapidly evolving information and communication technologies, and it is necessary to consider learner factors such as attitudes and digital literacy toward online learning.
