  • 본 연구는 급변하는 유비쿼터스 환경에 발맞추어 스마트의 발달과 시장의 확대로 수많은 교육용 앱이 쏟아져 나오고 있다. 학교 수업 내용에 대한 앱은 전무한 현실에서 교수자가 직접 앱을 개발하여 학교 수업에서 활용하는 방안을 연구하고자 한다. 스마트폰의 최대 장점인 시간과 장소에 구애 받지 않고, 언제 어디서나 학교 수업 내용을 학습하고 교수자와 학습자 간의 커뮤니케이션이 원활히 이루어지는 학습 환경을 만드는데 있다. 또한 앱을 외주 업체나 프로그래머에게 의뢰하지 않고 컴퓨터 비 전공자도 개발 가능한 저작도구를 이용하여 쉽고 빠르게 앱을 제작한다면 교육 현장에서 수정 및 업데이트가 용이하고 시간과 비용 낭비를 줄임은 물론 학습자의 학습 능률과 학습 효과를 최대한으로 높이고자 한다.

  • Purpose: Because it is important to prevent adolescents from becoming involved in smoking, this study was done to explore important factors influencing cigarette use and the increase in smoking frequency. Method: For this study the Korea Youth Panel Survey (KYPS) was analyzed. Because the KYPS is longitudinal, a fixed effect regression method was used to control for the effects of time-independent factors. More specifically, a logistic regression was used to explore factors affecting cigarette use, and a Poisson regression was used to explore smoking frequency. Result: As the adolescents got older, the number of male adolescents who tried smoking increased, while the number of female adolescents who tried smoking decreased. Also, the frequency of cigarette use among male and female smokers increased over time. Significant factors affecting cigarette use were friends who smoked, delinquent behavior, and loneliness at schools. Important factors affecting the increase in smoking frequency were grade (e.g., the 2nd- and 3rd-year of middle school), friends who smoked, delinquent behavior, monthly pocket money, expectation for the highest level of education, and attack tendency. Conclusions: To solve the problems linked to adolescent smoking, it is critical to develop intervention programs that target specific homogeneous subgroups of smokers, and that take into consideration gender difference in smoking and factors affecting levels of smoking behavior.

  • An electronic micropayment system, one of electronic payment systems, is suitable especially when a small amount of money is to be paid frequently in order to purchase on-line goods (i.e. database search, software distribution, electronic news service, etc). In addition, since the amount of payment is small, possible damages caused by system failures are lower than other payment system. In this paper, a micropayment protocol in electronic commerce environments on the Internet is proposed, based on the PayWord system. And a micropayment electronic commerce system which executes the protocol proposed is implemented. Unlike the PayWord system, however, the micropayment protocol proposed in this paper is designed in such a way that a merchant does not need to request a payment at the end of every business day since a customer cannot purchase goods beyond length of hash chains, which is specified on a certificate. In addition, the system is able to check the validity as well as the duplicate spending of hash chains. The electronic micropayment system with the proposed protocol is consists of Customers, Merchants, and Brokers. Customers are implemented on Windows NT 4.0 using VC++. Merchants are implemented on Solaris 2.5.1 and gcc 2.8.0 using Netscape Web Server and CGI Methods. HP UX 10.20 is used for Brokers.

  • IT기술의 급속한 발전으로 인해 인터넷 상에서 많은 사람들이 메신저를 이용해 실시간으로 대화를 나누거나 업무처리를 위한 파일 공유 등에 메신저를 사용하고 있다. 하지만 이런 편리성을 이용해 금전 요구 등의 메신저 피싱 범죄가 발생하고 있으며, 범죄자가 자신이 접속한 IP 주소를 은닉하기 위하여 Proxy와 같은 우회기법을 사용할 경우 범죄자의 Real IP 주소를 확인하는 것은 어려운 실정이다. 본 논문은 ARIT 기법을 이용해 2채널 방식으로 접속 IP 주소와 ARIT Agent를 이용해 얻은 Real IP 주소를 수집하여 별도의 확인 과정을 거친 후, 사용자가 정상적인 방법으로 접속했는지 여부를 판단하여 사전에 발생할 수 있는 메신저 피싱에 대응할 수 있는 방안에 대해 제시하고자 한다.

Results - Using the step-wise regression method, the result shows that the influential factors to create customer value are cost and company image. The result suggests a company to improve its costs components and its company image in order to increase the customer value. Conclusions - The research shows that costs play a critical role, and completed with the company image to form the customer value variable. This shows that mostly customer formed their value based on costs they sacrificed. Mainly, this evaluation is monetary cost based, while Indonesian customers tend to have a high value for money demands.

  • The principal measure of housing demand is income and the preferences expressed by households through their respective indifference curves. In this context, housing essentially becomes a derived demand, i.e., the household consumes land and a location (or distance-in time and money costs), according to its relative preferences for space, accessibility, and all other nonhousing goods. This paper attempts to deal with both aspects of housing (apartment) demand and household mobility in the Seoul Metropolitan Areas. Housing services will be measured using hedonic regression technique. From observations on the market prices of dwelling units and on the underlying characteristics of housing, one can estimte the relationships between the two empirically. In predicting the probability of the future moves into new towns in the Seoul Metropolitan areas, the best predictors of the future moves into new best predictors are found to be the degree of satisfaction not only with the current residence as a whole, but with some of the major amenities, accessibility and child education. The reasons for moving into new towns are diverse depending on the households' current situation; the most frequently cited is "improvement of housing conditions," followed by "improvement of living environment," "asset improvement" and "home ownership". It appears that people move houses because of a dissatisfaction with their current housing status, relative their income or needs, or a desire to improve their housing and neighborhood amenities, or both. On the other hand, it is clear that the development of new towns in the Seoul Metropolitan Areas should be based on the analysis of housing demand and the pattern of household mobility in Seoul housing market.sehold mobility in Seoul housing market.

  • Although the internet is useful for transferring information, Internet auction environments make fraud more attractive to offenders because the chance of detection and punishment are decreased. One of fraud is phantom transaction which is a colluding transaction by the buyer and seller to commit illegal discounting of credit card. They pretend to fulfill the transaction paid by credit card, without actual selling products, and the seller receives cash from credit card corporations. Then seller lends it out buyer with quite high interest rate whose credit score is so bad that he cannot borrow money from anywhere. The purpose of this study is to empirically investigate the factors to detect of the phantom transaction in online auction. Based up on the studies that explored behaviors of buyers and sellers in online auction, bidding numbers, bid increments, sellers' credit, auction length, and starting bids were suggested as independent variables. We developed an Internet-based data collection software agent and collect data on transactions of notebook computers each of which winning bid was over 1,000,000 won. Data analysis with logistic regression model revealed that starting bids, sellers' credit, and auction length were significant in detecting the phantom transaction.

One of these frauds is the phantom transaction, which is a colluding transaction by the buyer and seller to commit the illegal discounting of a credit card. They pretend to fulfill the transaction paid by credit card, without actually selling products, and the seller receives cash from the credit card corporations. Then the seller lends it out with quite a high interest rate to the buyer, whose credit rating is so poor that he cannot borrow money from anywhere else. The purpose of this study is to empirically investigate the factors necessary to detect phantom transactions in an online auction. Based upon studies that have explored the behaviors of buyers and sellers in online auctions, the following have been suggested as independent variables: bidding numbers, bid increments, sellers' credit, auction lengths, and starting bids. In this study. we developed Internet-based data collection software and collected data on transactions of notebook computers, each of which had a winning bid of over W one million. Data analysis with a logistic regression model revealed that starting bids, sellers' credit, and auction length were significant in detecting the phantom transactions.
