There has been increasing demand of hypermedia as computing and educational environment change. Most authoring tools developed recently have various built-in functions., but they are not enough to create hypermedia program or easy to learn. Even though teachers might try to develop hypermedia program with existing authoring tools, they usually come to face with the difficulties of creating new nodes, adding new data, or keeping user's activity records. Therefore, this study investigated to present a prototype of Educational Hypermedia Editor that can be conveniently used in hypermedia programs. According to the theories of courseware design, instructional design, learning theory, and hypertext and hyperemia, design strategies for the study were selected. Based on the analysis of the characteristics of domestic authoring tools as well as foreign authoring tools, the Educational Hypermedia Editor that has authoring and executing mode was designed and developed. Because the Educational Hypermedia Editor was designed for information retrieval CAI(Computer Assisted Instruction) materials, it is expected that the Educational Hypermedia Editor will be extensively used in the urea of social science classes, investigation studies, and information processing studies.

This study was to examine the pattern of visual interpretation in the process of eye-tracking. I categorized the subjects' observation inclination for analysis so that I could find out which element the user observing the space concentrated and explored. First, for 2 minutes of observation, there occurred 171 times of eye-fixations and 9.8 times of observation frequency on average, which showed that the subject, through this observing fixation, spent 44.5% of the entire time performing the visual activity in order to acquire the "visual understanding" of the lobby-space. Second, I found out that there was a consistent observation type as the time passed. I could categorize the subjects observing the space into 6 concentrating types and 3 discontinuing ones of observation types, which category can be utilized as data for analyzing the subjects' characteristics at space-observation. Third, the type, which was so intensive as to get the visual understanding on the space, was mostly of the case that (1) the subject had a kind of high degree of observation type, exploring the space, again having high degree of the observation type [Type A], (2) the subject repeated the concentration from the early part to the latter [Type C], which can be considered to be the observation type generally shared. Fourth, in the case of observing the space, 45.8% of the subjects showed a high rate of concentration at the time of starting the observation and in less than two minutes. The subjects of type A can be considered to understand the space visually by distinctively repeating the concentration and exploration.

Spyware is any technology that aids in gathering information about a person or organization with-out their knowledge. Software designed to serve advertising, known as adware, can usually be thought of as spyware as well because it almost invariably includes components for tracking and reporting user information. A piece of spyware and adware affect computers which can rapidly become infected with large numbers of spyware and adware components. Users frequently notice from un-wanted behavior and degradation of system performance, such as significant unwanted CPU activity, disk usage, and network traffic which thereby slows down legitimate uses of these resources. The presence of situation will continue because of rapid expansion of Internet usages. Therefore, security solutions, such as anti-adware and anti-spyware, for recovering these malfunction due to the malicious programs must be developed. However, studies on the malicious programs are still not sufficient. Accordingly, this paper has studied the malicious program techniques, based on the results of analysis of present adware and spyware techniques by employing collected samples, and presents efficient measures for blocking and remedying the malicious programs.

In this paper, daily life stress monitoring system is proposed. The proposed wireless ECG module, reducing the noise and increasing the size of signal, amplification circuit was designed for. Using HRV(Heart Rate Variability), extracted by measuring R-wave, stress diagnostic algorithms to assess the stress of human emotion were developed. For monitoring the activities, the proposed system is consist of small rectangular size for portable and by simple measurement it is possible to measure at any time. Through experiments, the proposed approach to represent user's stress level can be confirmed. Through that, it can see appropriate structure to obtain R-wave for stress assess as well as high resemblance to the clinical electrocardiogram. In this paper, performed experiments was developed nonrestraint measuring and wearable wireless biometric scanner that is able to monitor the heart's electrical activity of everyday life.Using this, the algorithm system, that is able to assess stress index through time-domain and frequency-domain analysis of the front and the rear of performing stress load protocol, was developed,

The mobile social networking application Instagram is a well-known platform for sharing photos and videos. Since it is folksonomy-oriented, it provides the possibility for image indexing and knowledge representation through the assignment of hashtags to posted content. The purpose of this study is to analyze how Instagram users tag their pictures regarding different kinds of picture and hashtag categories. For such a content analysis, a distinction is made between Food, Pets, Selfies, Friends, Activity, Art, Fashion, Quotes (captioned photos), Landscape, and Architecture image categories as well as Content-relatedness (ofness, aboutness, and iconology), Emotiveness, Isness, Performativeness, Fakeness, "Insta"-Tags, and Sentences as hashtag categories. Altogether, 14,649 hashtags of 1,000 Instagram images were intellectually analyzed (100 pictures for each image category). Research questions are stated as follows: RQ1: Are there any differences in relative frequencies of hashtags in the picture categories? On average the number of hashtags per picture is 15. Lowest average values received the categories Selfie (average 10.9 tags per picture) and Friends (average 11.7 tags per picture); for highest, the categories Pet (average 18.6 tags), Fashion (average 17.6 tags), and Landscape (average 16.8 tags). RQ2: Given a picture category, what is the distribution of hashtag categories; and given a hashtag category, what is the distribution of picture categories? 60.20% of all hashtags were classified into the category Content-relatedness. Categories Emotiveness (about 4.38%) and Sentences (0.99%) were less often frequent. RQ3: Is there any association between image categories and hashtag categories? A statistically significant association between hashtag categories and image categories on Instagram exists, as a chi-square test of independence shows. This study enables a first broad overview on the tagging behavior of Instagram users and is not limited to a specific hashtag or picture motive, like previous studies.

This study aims to provide basic data for planning the supply and demand of urban parks and setting up facilities in urban parks that reflect the use patterns of visitors. The study was conducted by surveying the total number of urban park users and the number of users for different time zones and analyzing their use patterns through on-site surveys at 17 urban parks located in seven cities/counties in Gyeonggi province. The result showed that as for distribution of urban park users by time zone, the number of users was highest in the afternoon. Between 7 and 9 o'clock in the morning in weekdays, many users came to urban parks for their morning exercises. There was hardly no difference between male and female. When the number of users of 17 urban parks was surveyed, a park was used by 734 people per day on weekdays in average. When the total number of users per year was estimated, a resident nearby a park visited the place 4.7 times a year in average. In addition, the analysis showed that the number of users of man-made parks was twice as high as that of natural parks. The number of users did not vary depending on the size of a park. As for use patterns by time zone, no difference was found in activity types between parks larger than 100,000 $m^2$ and those less than 100,000 $m^2$. Usually, in the morning, users came for exercises In the afternoon, users visited the parks for more diverse purposes. In the evening, they tended to visit parks to work out and wrap up a day. Going forward, the outcome of this study should be utilized as important data for analyzing the demand and supply of urban parks. In addition, the number of users by time zone and their use patterns should be fully considered when introducing facilities in parks.
