This study hypothesized and tested multiple influences(based on IRT and SIT) in a study of e-mail attitudes and use. The media included e-mail, fax, letters, and face-to-face meetings. This study focused on e-mail. The outcomes included experiences, skills, attitudes toward e-mail, and e-mail use. Results suggested that attitudes toward e-mail were influenced by experiences, skills, toward e-mail, and e-mail use was influenced by attitudes toward e-mail. The our results were consistent with ones predicted by IRT and SIT.

This study was conducted to investigate the determinants of e-mail use and its effects on the organizational effectiveness of hospital administrative workers. Data were collected from 147 administrative workers at 2 university hospitals in Seoul using self-administered questionnaires and analyzed using t-test, ANOVA, and multiple regression analysis. The major findings of the study are as follows: 1. There are significant differences in the use of e-mail for business purpose in terms of the gender, age, status, and education level. Workers who are men, over 30s, high status, and highly educated were more likely to use the e-mail. As for the private use, there are significant differences only in terms of the age level. 2. The more job characteristics need to use e-mail, the more workers have computer skills, and the more favorable the organizational culture is to using the e-mail, the more frequently the workers use the e-mail for both business and private purposes. 3. Job characteristics and personal computer skills have significant positive effects on the use of e-mail for business purpose. However, for the private purpose, only personal computer skills have a significant effect on the use of e-mail. 4. The level of the e-mail use for the business purpose has a significant effect on the work productivity, communication, and job satisfaction, while the level of the e-mail use for the private purpose has a significant effect only on the communication and job satisfaction. The implications for hospital administrators and suggestions for further research are discussed.

There are POP3(Post Office Progocol 3) and IMAP4(Internet Message Access Protocol 4) for E-Mail service of wire Internet For mobile e-mail service that use wireless Internet, must use exclusive use mobile e-mail server in the case of POP3 e-mail or flow e-mail conversion and because e-mail is kept in sever side with remote file server in case of IMAP4 mail that is used by Web-Mail, utilization of mobile e-mail service is difficult by mobile client who there is no IMAP4 rules. This thesis embodying e-mail extraction engine for mobile that do to design markup language converter of XML base, and use Web-Mail of recently been generalizing IMAP4 base in mobile, presented mobile e-mail service method to do so that can use Web-Mail that is based on IMAP4 as well as POP3 mail service in mobile environment.

Despite the adoption of advanced computer technologies by organizational makers, the actual use of E-mail by managers and professionals has tended to be lagging and the potential benefits of these technologies have not been fully realized. Much of the prior research in this area has focused on the utility or perceived usefulness of E-mail as the principal motivating factor in using them. Relatively little attention has been given to the recreational basis of E-mail usage. The limited research in this area indicates the use of E-mail can be stimulated by the intrinsic joy and enjoyment derived. The objective of this study is to integrate these perspectives on the reasons underlying the use of E-mail and to examine simultaneously the relative influence of motivators identified in the literature as affecting individuals' decision to use E-mail. The study focuses specifically on E-mail because of its ubiquitous usage.

Most organization are using E-mail(electronic mail) currently, but we seldom see the organizational success from the E-mail utilization strategically. There are many research which are focusing on the selection and usage of E-mail as a electronic communication media based on Information Richness Theory and Critical Social Theory. The purpose of this study is to investigate the effects by using E-mail through providing the model of perceived impacts. This model considers the moderate factors such as top management supports, organizational usage, and organizational pressure based on CST. Also it provides the guideline how to use E-mail strategically.

The purpose of this study was to investigate guidelines for instructional use of e-mail and the method in the present investigation was followed by an analysis of research literatures. This study suggests the following conclusions. First, instructors should use e-mail effectively to improve communication between an instructor and a learner or learners. Communication was essential to support a good instruction. Second, to use effectively e-mail in teaching and learning process, guidelines should followed by considering e-mail characteristics. These guidelines were as follows: (1) Spelling and grammar should be followed correctly. (2) Messages should be followed shortly and concisely. (3) Summaries should be stated in your first sentence. (4) Messages should be responded rapidly. (5) Messages should be responded kindly. (6) Sarcasm and humor should be used carefully.

With the advent of virtual money such as bit coins, interest in the block chain is increasing. Block Chain is a technology that supports Distributed Ledger and is a versatile technology applicable to various fields. Currently, the block chain is conducting research for various applications such as virtual money, trade finance, marketplace, power market, image contents service, and IoT. The technologies that make up the block chain are smart contract, digital signature/hash function and consensus algorithm. And these technologies operate on P2P networks. In this paper, we have studied e-mail system based on the ethereum which is one of the block chain based technologies. Most legacy mail systems use SMTP and the POP3/IMAP protocol to send and receive e-mail, and e-mail use S/MIME to protect the e-mail. However, S/MIME is vulnerable to DDoS attacks because it is configured centrally. And it also does not provide non-repudiation of mail reception. To overcome these weaknesses, we proposed an e-mail system model based on ethereum. The proposed model is able to cope with DDoS attack and forgery prevention by using block chain based technology, and reliable recording and management among block chain participants are provided, so that it is possible to provide a non-repudiation function of e-mail transmission and reception.

Data of 650 college students in the nation were collected by mail in 2001 Nov. Students preference over cyber communication methods were SMS message, messenger, blog, e-mail in that order. Younger students prefer SMS messages while older students prefer e-mail in relative term. Mobile phone is used more for SMS message than voice communication which is more so with females. The rate of non e-mail use is 57.8%, particularly males(61.9%) and younger students(69.4%) are higher. E-mail, once was very high in use, is being replaced by new media. Suggestion for e-learning environment are being connected, immediacy, active use of blog, more use of fun multimedia information.

This study designs and implements a new approach to the classification of e-mail requests from customer based on machine learning techniques. The work on building an electronic mall classifier can be cast into the framework of text classification, since an e-mail is a viewed as a document, and judgement of interest is viewed as a class level given to the e-mail document. It is also implemented an e-mall based automated response system that integrate with Call Center in a practical use.
