  • Purpose: The purpose of this study was to evaluate whether the effect of the Internet diabetic education on plasma glucose in people with hyperglycemic diabetes. Method: A randomized design with control and experimental groups being assessed pre- and post-intervention was used. Twenty-two patients were randomly assigned to an intervention group and 21 to a control group. Participants were requested to input the blood glucose level weekly in http://www.biodang.com by cellular phone or wire Internet for 3 months. The researcher sends optimal recommendations to each patient using short message service(SMS) of cellular phone and wire Internet weekly. Results: Patients in the intervention group had a mean decrease of 1.3% in glycosylated haemoglobin ($HbA_1c$) levels and those in the control group had no significant difference. There was a significant mean change in 2-hour postprandial blood glucose(2HPPG) for the intervention group, with a mean change of-75.2mg/dl. The mean change in the control group was, however, not significant. Conclusion: These findings indicated that a web-based intervention using SMS of cellular phone improved $HbA_1c$ and 2HPPG.

  • While internet and cellular phones are very attractive to adolescents, they cause a lot of problems because of adolescent's addiction to internet and cellular phones. The purpose of this study is to investigate relations among overuse of internet and cellular phone and academic achievement with middle school students according to their sex and grade. For this purpose, the survey consist of 44-item, self-administered paper-and-pencil questionnaire from 444 two middle schools students located in Busan. Also, their academic achievements were used for statistical data processing. As a result, firstly, middle school students did not tend to be so seriously addicted to the internet and cellular phones. The internet was used more by male students and cellular phones by female students, and the more male and female students used the internet, the higher they tended to use the cellular phones. There was a negative correlation between the tendency of internet use and academic achievement, but there were no significant differences between genders. In terms of the tendency of using cellular phones and academic achievement, there were no correlations among male students, but there was a negative correlation in female counterparts. Secondly, in terms of grade, the 2nd-grade students had a higher tendency to use both of them than the 1st- and 3rd-grade counterparts. The tendency of using the internet and cellular phones, in each grade had significantly static correlation and the higher they tended to use the internet, the lower they had academic achievement the 3rd-grade. On the other hand, the tendency of using cellular phones, only 2nd-grade students had low academic achievement.

  • The technology of wireless internet has been recently developing very fast and affecting everyday life using mobile media. In this paper, we propose an algorithm that can get necessary information such as image pixels from photos taken by mobile phones and search approximate values from reference database in the internet. This algorithm is expected to enable us to use a mobile phone to take a picture of something we see in every day life and go online to search for some information on that entity in the internet. An example system employing this proposed algorithm is illustrated in this paper.

  • Recently, the study of smart phone user habits has become a highly focused topic due to the rapid growth of the smart phone market. Indeed, sequential pattern analysis methods were efficiently used for web-based user habit mining long time ago. However, by means of simulations, it has been observed that these methods might fail for smart phone-based user habit mining. In this paper, we propose a novel approach that leads to a considerably increased performance of the traditional sequential pattern analysis methods by reasonably cutting off each chronological sequence of user logs on a device into shorter ones, which represent the sequential user activities in various periods of a day.

  • This paper provides Bus Information System(BIS) implementation based on the Smart-phone APPs using GPS information. Nearly all of recent smart-phones are equipped with the GPS feature. Bus driver's smart-phone can send the position information using its GPS information periodically and on events. On receiving those information, servers can process those into the information that can be used by individual users and bus stop information panel. The proposed BIS based on smart-phone APPs is expected to be used publicly with the special process that enables the smart-phone APPs only in the specific bus.

  • In order to block mobile junk messages automatically, many studies on spam filters have applied machine learning algorithms. Most previous research focused only on the accuracy rate of spam filters from the view point of the algorithm used, not on individual user's preferences. In terms of individual taste, the spam filters implemented on a mobile device have the advantage over spam filters on a network node, because it deals with only incoming messages on the users' phone and generates no additional traffic during the filtering process. However, a spam filter on a mobile phone has to consider the consumption of resources, because energy, memory and computing ability are limited. Moreover, as time passes an increasing number of feature words are likely to exhaust mobile resources. In this paper we propose a spam filter model distributed between a users' computer and smart phone. We expect the model to follow personal decision boundaries and use the uniform resources of smart phones. An authorized user's computer takes on the more complex and time consuming jobs, such as feature selection and training, while the smart phone performs only the minimum amount of work for filtering and utilizes the results of the information calculated on the desktop. Our experiments show that the accuracy of our method is more than 95% with Na$\ddot{i}$ve Bayes and Support Vector Machine, and our model that uses uniform memory does not affect other applications that run on the smart phone.

  • Purpose: This study was done to examine factors influencing cell phone addiction for middle school students by gender. Methods: The participants were 228 male students and 228 female students in two middle schools. Data were collected through self-report questionnaires, and analyzed using the SPSS/WIN 19.0 program. Results: Cell phone addictions of female students are higher than those of male students. Factors influencing cell phone addiction for male students were mimicry, sending text message on weekdays, immediate self-control, grade, syntony, and monthly call charge, explaining 42.2% of variance in cell phone addiction. Factors influencing cell phone addiction for female students were internet addiction, sending and receiving text message on weekends, immediate self-control, long-term self-control, use time, main use, syntony, and monthly call charge, explaining 46.8% of variance in cell phone addiction. Conclusion: The results indicated that cell phone addiction and its influencing factors differed by gender. Therefore the approach to effective cell phone addiction management program for middle school students should consider gender differences.
