The purpose of this paper is to clarify the distribution system and the spatial characteristics of sales for the internet shopping mall on the basis of its off-line presence. The distribution system of this internet shopping mall is divided into the goods selection process and the product delivery process to consumers according to the function and role of the distribution center which is performed by cooperative companies. The internet shopping mall uses a different distribution system from the off-line department store, outsourcing the delivery process to door-to-door delivery companies in order to reduce costs and to increase the speed of delivery. Sales in the internet shopping mall are concentrated in the delivery unit area where the main office is located. Accordingly, in the case of the internet shopping mall based on an off-line presence, the mail-order business does not fully overcome the limitations arising from space. Also, the main factors influencing the value of sales, according to the area, are the number of women aged 20 to 49 and the distances involved.

This study examined the virtual methods of service delivery being deployed by librarians in private universities in Nigeria. The objective of the study was to analyse the virtual methods of service delivery among librarians and determine the predominant method used among the librarians. Survey research design was adopted for the study. Total enumeration technique was adopted for the study. A population of 181 librarians from 45 private universities in Southern Nigeria were involved. Data were gathered, analysed and presented using frequency counts, percentages, mean and standard deviation. The study found that librarians used different virtual methods of service delivery. Library website 157 (90%) and e-mail 132 (76.3%) were the prominent electronic media used by librarians while Facebook 59 (34%) and Whatsapp 57 (32.9%) were the predominant social media platforms applied for service delivery by librarians. Electronic media were more used for latest publications arrival, as well as library education and document delivery services while social media were more used for reference services and selective dissemination of information. In conclusion, virtual methods of service delivery were deployed by librarians in private universities for service delivery. In comparing the virtual methods, librarians used more of electronic media than social media to deliver services to their users. Therefore, electronic media were predominantly used than social media, many of the virtual methods were found to be underutilised while recommendations were proffered.

With the change of times, the postal service environment and the customer's service needs are changing greatly. In this paper, we researched to improve inefficient service for registered mail by using ICT technology. ICT-based non-face-to-face smart mailbox system can deliver mail efficiently and improve customer satisfaction. In addition, it is expected that it will be able to reduce the work intensity of the mailman delivery of mail and greatly improve the working environment of the on-site deliverymen.

As computers and networks become popular, distributing information on the Interment is common in our daily life. Also, the explosion of the Internet, of wireless digital communication and data exchange on Internet has rapidly changed the way we connect with other people. But secure mall is gamins popularity abroad and domestically because of their nature of prodding security. That is. it has been used a variety of fields such as general mail and e-mail for advertisement But, As the data transmitted on network can be easily opened or forged with simple operations. Most of existing e-mall system don't have any security on the transmitted information. Thus, security mail system need to provide security including message encryption, content integrity, message origin authentication, and non-repudiation. In this paper, we design implement secure mall system with non-repudiation service and encryption capability to provide services for certification of delivery and certification of content as well as the basic security services.

We consider a problem of presort and loading of commercial bulk mails in a mailing service. Here, presort is the process by which a mailer prepares mail so that it is sorted to at least the finest extent required by the mailing service provider for the (discounted) price claimed. The problem is formulated as a special type of transportation problem. To solve industrial-sized problems, we develop an efficient heuristic algorithm and perform experimental tests on randomly generated problem instances. Results of the tests show that mailers can save mailing cost much more when they use small-sized mail trays with less frequent mailings. Also, large-sized mailers can obtain much more cost saving than small-sized mailers. In addition, cost saving effect is influenced by delivery area distribution of mails and fluctuation of mailing demand.

To find out the status of document delivery and interlibrary loan services and the use of information technology in special libraries, questionnaires were sent to 328 special Libraries nation wide with at least 1 librarian, listed In the Korean Libraries Statistics 1994-1995(1996). $46.6\%$ were returned and 152 Questionnaires were analyzed. For document delivery, $61.3\%$ use BLDSC$47.5\%$ use KINITI. 87 libararies $(57.2\%)$ participate In interlibrary loan activities. To send requests, FAX and telephone is used the most, while FAX and print copy is used the most to receive the requested documents. $45-75\%$ use various information technology including online databases, Internet, e-mail, etc., and the use of information technology was related to the budget of the libraries. The costs, budgets, and slowness was the problems raised by the most. To improve the document delivery services, the most urgent thing is establishing cooperative system using BBS or Internet. Network systems to facilitate interlibrary loan should be established ultimately.

Recently, the Internet enhanced by development of IT makes the processing and exchanging of information, As the Internet is sending and receiving digitized documents over the Internet e-mail system. The security of document information is being threated when exchanging digitized documents over an open network such as the Internet. The degree of threat is even higher when sensitive documents are involved Therefore, in this paper, the secure e-mail system on a client is designed and implemented in order to make secure exchanging of digitized documents. By using the public key infrastructure in which encrypted mail transmission, proof of delivery and integrity of the message are garanted, unauthorized manipulation, illegal acquisition and mutual authentication problem can be prevented in order to secure the document information which is crucial and sensible when exchanging the digitized document over the Internet. Futhenmore, by using the SET protocol based on public key cryptography, the secure mail system is designed and implemented in order for the users not having any professional knowledge to deal with the system easily and friendly in GUI environment.

Recently, food delivery apps are seeing rapid growth into a market worth 1 trillion won under a simple but unique business model of connecting nearby restaurants with consumers via smartphone. Though basic similarities with social commerce exists in aspects such as mail-order sales intermediaries, startups, types of services and market competition structure, food delivery apps resemble social commerce in many ways in that they use excessive marketing to secure market dominance, causing a spike in consumer complaints. If the excessive marketing and increase in customer complaints are not rectified, the food delivery app could also see rapid decline as it gradually grows distant from consumers, just like social commerce. Accordingly, this study will identify the factors consumers recognize as important for continuous use vis-a-vis social commerce and food delivery apps to perform an empirical analysis on what areas need improvement. After deriving the four upper factors of product, information system and service along with eight sub-factors by referring to existing literature, the areas with opportunity for improvement were derived through satisfaction level and relative importance evaluation. The results of this study present a strategic direction for maintaining customers of social commerce and food delivery apps.
