Electronic commerce, the act of trading online, with its myriad of potential has been seldom looked at within the context of developing countries. E-commerce presents SMEs in developing economies the opportunity to adequately compete on a global stage. The exponential growth of e-commerce in developed economies further widens the financial gap between developed and developing economies. This study looks at a practical e-commerce adoption framework for Ghanaian SMEs and by extension, developing economies and looks at the net benefits that are available to current adopters. The study uses structural equation modeling, using Partial least squares (PLS) regression to analyze the data in the research. Using PLS algorithms as well as bootstrapping calculations. It combines the use of surveys (154) and interviews (38) as means of data collection. The findings of the research indicate that there is a need for legislation on e-commerce trading to regulate the trade in Ghana, with policies such as e-contracting and e-signature laws among others. Also, a current call for an expansion of the mobile payment methods within the country. For the private investor, a ripe market for logistics services. The study also proposes a simple guideline for SMEs looking to adopt or expand their e-commerce usage, that considers technological, organizational and environmental factors that come to play within e-commerce adoption.

Global economy is moving to digital economy accelerated by the rapid development of ICT (information and communication technology). However, the progress in e-business in developing countries has been slow due to the lack of experience, technology, and basic infra structure. One way to solve this problem is to provide them with customized e-business solution, training, and contents service. In this paper, we design an E-business Training Supporting System (E-TSS) for developing countries. It consists of a simple business blog to support business web page and a customized e-business solution. The E-TSS is customized for individual country. This customization becomes more effective utilizing an intelligent agent based upon recognizing unique characteristics such as language and time. The E-TSS is implemented and utilized by APEC (Asia-Pacific Economic Cooperation) Women's e-Biz Center.

In existing internet, e-mail protocols including POP3 and IMAP4, provide e-mail services fir exchanging messages with texts, hypertext and images as well. For the e-mail services in wireless mobile network, mobile e-mail service providers have to install a mobile exclusive e-mail server or have to convert e-mail to mobile exclusive e-mail with wireless application format in case of POP3 protocol. In the e-mail service of IMAP4 case known as web-mail, it is difficult to view e-mail directly from server without IMAP4 mobile client because e-mail is stored in mail server side with remote file server. In either case, it also has the problems of viewing the e-mail of hypertext and image information at mobile. This paper provides e-mail extraction engine with image and hypertext conversion facilities that can be applied in wireless mobile internet and it is optimized in mobile communication environments such as a small display, small size of memory with web-mail protocol based on IMAP4 as well as POP3 mail protocol.

G. Deleuze a $exerc{\acute{e}}$ sa philosophie $cin{\acute{e}}mathographique$ dans ses œuvres essentielles $Cin{\acute{e}}ma$ 1: l'Image-Mouvement(Minuit:1983) et $Cin{\acute{e}}ma$ 2: l'Image-Temps(Minuit:1985) qui n'indiquent pas l'histoire $cin{\acute{e}}mathographique$ mais la taxinomie, et par $cons{\acute{e}}quent$, de l'image et du code. Cette ${\acute{e}}tude$ consiste donc $\grave{a}$ rendre compte la de l'image que G. Deleuze touche dans cette $d{\acute{e}}finition$ et $\grave{a}$ $v{\acute{e}}rifier$ quelles images peuvent ${\hat{e}}tre$ $cat{\acute{e}}goris{\acute{e}}es$: comment. Nous distinguons l'image-mouvement et l'image-temps qui sont les $cat{\acute{e}}gories$ essentielles chez $Cin{\acute{e}}ma$. C'est surtout sur ce point que nous insistons. Dans ce cas, nous discutons aussi de la question des spectateurs du film qui conduit. Cette question permet susciter de la $mani{\grave{e}}re$ $d^{\prime}{\hat{e}}tre$ des spectateurs entre le film qui est $compos{\acute{e}}$ de l'image-mouvement dont G. Deleuze decrit comme 'classique' et le film qui est $trait{\acute{e}}$ de l'lmage-temps dont il $d{\acute{e}}finit$ comme 'moderne': quelle variation. Dans ce point $d^{\prime}{\acute{e}}tude$, G. Deuleuze ecrit cette question $mentionn{\acute{e}}e$ $\grave{a}$ travers son oeuvre $Cin{\acute{e}}ma$($\grave{a}$ voir ch.7, Volume2).

Recently, the malicious e-mail worm-viruses have been widely spreaded over the Internet. If the recipient opens the e-mail attachment or an e-mail itself that contains the worm-virus, the worm-virus can be activated and then cause a tremendous damage to the system by propagating itself to everyone on the mailing list in the user's e-mail package. In this paper, we have designed and implemented two methods blocking e-mail worm-viruses. In the fist method, each e-mail is transmitted only by sender activity such as the click of button on a mail client application. In the second one, we insert the two modules into the sender side, where the one module transforms a recipient's address depending on a predefined rule only in time of pushing button and the other converts the address reversely with the former module whenever an e-mail is sent. The lader method also supports a polymorphism model in order to cope with the new types of e-mail worm-virus attacks. The two methods are designed not to work for the e-mail viruses. There is no additional fraction on the receiver's side of the e-mail system. Experimental results show that the proposed methods can screen the e-mail worm-viruses efficiently with a low overhead.

While e-learners' satisfaction would be determined by qualify of e-learning environment including learning management systems, learning contents and interactions, the influence of quality on satisfaction can be changed by e-learners' self-regulated efficacy The objective of this study is to show difference of the relationship between qualify and satisfaction In e-learning by self-regulated efficacy. For this purpose, we propose a research model which consists of five quality factors in e-learning as explaining variables, satisfaction as a result variable and self-regulated efficacy as a control variable. For empirical test of this model, the sample is collected from e-learning classes in a college and divided into two groups by self-regulated efficacy in order to analyze the effects of control variable. By multi-group analysis, we show two groups are different from each other in the relationship between quality and satisfaction of e-learning environment.

Recently, many organizations in various industries have introduced e-businesses for the purpose of adding value to their businesses. However, due to no comparable business models to e-business in the past, there are no reliable yardsticks to predict the performance of an e-business. This paper considers an environmental change analysis as a means to resolve this difficulty. System Dynamics (SD) could be a useful tool to generate effective results by examining the e-business model. SD model is developed to analyze the effects of an e-sales channel which was appended to the existing sales channels in the steel manufacturing industry. The results show an increase in average price and sales volume through the use of an auction process on the e-marketplace. Stocking expenses are reduced as well by the increase of the sales turnover. A possible scenario was adopted to the developed simulation model and investigated strategic issues to draw desirable strategies with market changes.

The aims of this study are to determine if the perceived risk of e-commerce affect the Internet shopping mall users' decision to pre-purchase an item via e-commerce, to find out if there are differences among the induced perceived risk according to gender, and to verify if the perceived risk according to gender have a correlation to a person's decision to pre-purchase an item via e-commerce. It can thus be concluded that the pre-perceived risk of e-commerce affect the Internet shopping mall users' purchase intention. Different results were obtained, though, according to gender. Moreover, the perceived risk of e-commerce based on gender and the purchase intention of the Internet shopping mall users were shown not to have a correlation. This means that although slightly different study results were presented, e-commerce purchasers can use these results to recognize the risk of e-commerce.
