The purpose of this study is to examine specific consumer problems in internet commerce and analyze them in the age of information. The way of sorting consumer problems in internet commerce from this study. For this empirical analysis, the data was collected 319 consumers by internet on-line survey from Feb. 13 to Feb. 20, 2000. The methods for study was frequency, percentage, mean, correlation, multiple regression using SAS PC program. The major findings of this study were as follows: 1. The level of consumer problem experiences in internet commerce was examined. The problems of privacy was the most problem and the problem of price was the second. Then delivery, advertisement, information was next, and the problem of quality, and A/S, change, cancel was the next consumer problem. 2. Among factors influence on experience consumer problem in internet commerce, the amount of usable money, information search were significant.

In this paper, we designed a new type of X-internet framework by using Flash component and server service API and analyzed its performance. Proposed X-internet framework uses Flash MX Professional 2004, Java, and software which opened middleware and database. Since proposed framework use the server service API that we developed in this paper and Flash player, this framework does not need server module. Proposed framework enables to obtain design with dynamic user interface compare to Web application and enables to reduce development time. In analytical results, it has been shown that proposed x-internet framework have efficient characteristics such as network traffic, low development cost and dynamic user interface implementation. Since proposed X-internet framework can operate in environment of current developer friendly, it is useful for development of various new application programs and we confirm it through Flash web mail implementation by using proposed x-internet framework.

Purpose: The purpose of this study was to investigate the effect of high school students' internet addiction on their health status. Methods: The subjects of the present study were 237 high school students in KyongBuk province. Self-reporting questionnaire survey was conducted during the period from September to October 2009. Collected data were analyzed using SPSS PC+14.0 through descriptive statistics, t-test, ANOVA, Scheffe's test and stepwise multiple regression analysis. Results: With regard to internet addiction, 33.9% is at the early stage of internet addiction and 2.1% is severely addicted to internet. Health status was poorer in female, students with low economic status, less attention to children's health by parents, neglecting their children's internet use, single-parent, and severely addicted to internet. Factors significantly influencing on the health status included gender, internet addiction, parent's attitude about internet using time, interest in their children's health, economic status and internet using time ($R^2$=25.8%). Conclusion: The education program for preventing internet addiction considering these affecting factors is necessary.

Purpose: This study was conducted to understand the degree of Internet addiction, Internet expectation and self-efficacy and we also wanted to elucidate the factors influencing this addiction among the high school students in Korea. Method: A total of 348 high school students in the Gyeoung-gi, Daegu and Gyeoung-buk area were surveyed in this study. Data collection was conducted through the use of questionnaires. Results: Internet addiction among high school students in Korea was relatively low. In the overall ratio distribution, however, the students who were classified as either addicted or at risk of addiction accounted were a high percentage of the subjects, 31%. A positive or negative relationship was found between internet addiction and the research variables. Multiple regression analysis revealed that the most powerful predictor of Internet addiction was Internet expectations. Conclusion: Using the above results, it would be necessary to develop an Internet addiction prevention program for adolescents. There should be a qualitative study in the future for an in-depth understanding of internet addiction of adolescents.

A study was conducted to develop Internet Literacy Questionnaire(ILQ) to investigate the levels of user's knowledge on Internet literacy. ILQ was found to be reliable (showed an internal consistency) with Cronbach's alpha of 0.93(p-value<0.001) and valid with test-retest correlation of 0.90 (p-value<0.001). ILQ, composed of 21 questions, was developed to test four areas of user's Internet literacy: general experience on Internet, advanced experience on Internet, knowledge on Internet program languages, and Internet application software programs. These four factors represented 69.2% of the knowledge of all areas of Internet literacy. As a result, ILQ could be used to differentiate the levels of user's Internet knowledge as beginners, intermediates, and experts before any Internet application programs are to be developed.

The purpose of this study was to examine the effect on improving communication by conducting a tea culture convergence program for elderly people using facilities. The subjects of this study consisted of a tea culture convergence program for 3 months, 60 minutes once a week for 7 people using the Elderly Day Care Center in the H-S S welfare center. Psychological and behavioral changes related to communication by sessions were compared by comparing elderly patients at each session of the Tea Culture Convergence Program.Tea culture convergence program was found to have a positive effect on behaviors and attitudes related to communication among the elderly in the facilities. As a result of analyzing pre- and post-action and attitudes, the Tea Culture Convergence Program brought positive changes in communication by acting as emotional and social support for the elderly. These findings suggest that the Tea Culture Convergence Program is a psychologically necessary program for the elderly in that it shows that the Tea Culture Convergence Program is an effective program that promotes communication among the elderly in the facilities.

This paper suggests remote experiments using the internet for the control education. The remote experiment is composed of equipment server computers, networks accessible to internet, and real plants such as inverted pendulums, crane systems and microcontrollers. Additionally, it requires a server program that has I/O functions with plants and calculate the control, an interface program bridging between web and the server program, and the home page including the detail explanation for the usage. For effective educations, how to perform experiments and how to combine the experiment with lectures will be discussed. The simple experiments by entering a few control parameters and the complex experiments by designing overall controls, will be explained. Technologies related with the remote experiment and other possible remote experiment will be introduced. It is demonstrated that the remote experiment will be very useful, particular for control education where students have difficulties in performing the experiments for lack of experimental equipments.

Recently, computer hardware is evolving toward increasing the number of computing cores, not increasing the clock speed. In order to use the performance of parallelized hardware to the maximum, the running program must also be parallelized. However, software developers are accustomed to sequential programs, and in most cases, write programs that operate sequentially. They also have a lot of difficulty designing and developing software in parallel. We propose a method to automatically convert a sequential C/C++ program into a parallelized program, and develop a parallelization tool that supports it. It supports open multiprocessing (OpenMP) and parallel patterns library (PPL) as a parallel framework. Perfect automatic parallelization is difficult due to dynamic features such as pointer operation and polymorphism in C/C++ language. This study focuses on verifying the conditions of parallelization rather than focusing on fully automatic parallelization, and providing advice to developers in detail if parallelization is not possible.

Program Behavior Intrusion Detection Technique analyses system calls that called by daemon program or root authority, constructs profiles, and detectes modificated anomaly intrusions effectively. In this paper, the relation among system calls of processes is represented by bayesian network and Multiple Sequence Alignment. Program behavior profiling by Bayesian Network classifies modified anomaly intrusion behaviors, and detects anomaly behaviors. we had simulation by proposed normal behavior profiling technique using UNM data.
