  • 인스턴트 메시징(Instant Messaging:IM) 서비스는 인터넷상에서 사용자들 간에 간단한 메시지를 주고 받을 수 있는 유용한 통신 수단의 하나이다. 통상적으로 인스턴트 메시징 서비스는 Presence 서비스를 통하여 상호간에 온라인 상태를 제공받아 메시지를 직접 송수신하는 방식을 사용하는데 이는 사용자가 오프라인 상태일 경우에는 메시지의 송수신이 불가능함을 의미한다. 따라서 본 논문에서는 SIP(Session Initiation Protocol) 기반의 인스턴트 메시징 시스템을 구현함에 있어 메시지 서버를 이용하여 메시지를 보관 및 관리함으로써 상대방의 상태에 무관하게 메시지를 전송할 수 있도록 보완하였다. 또한 In working group에서 제안하고 있는 message waiting indication event package를 메시지 서버에 포함시켜 메시지의 정보 및 상태들을 제공받을 수 있도록 하였으며 사용자들이 메시지 서버의 사용을 명시할 수 있는 Caller Preference 기능을 시스템에 포함시켰다.

  • This study was conducted on a sampling of 700 mixed college students from seven different schools nationwide by written questionnaire to evaluate the value system of convenience foods among Korean college students. Korean students put value on the following categories of convenience foods in order; convenience, taste, price, appearance, appliance to daily life, variety, locality, nutritional value, originality, improvement required, cleanliness and tradition. Significant differences between the sexes occurred in categories as cleanliness and convenience, since females considered convenience foods as convenient but not so clean (safe to eat). This study also conducted factor analysis on 24 individual convenient foods. Noodles laid emphasis on nutritional value; where refrigerated foods, ready to eat (RE) side dishes, on-the-spot kimbab, and sandwiches focused on cleanliness. Noodles. cereal, and instant soup focused on price. Frozen pizza, noodles, retort, RE meat, ham, fish cakes were dependent on locality and traditionality. Noodles, instant food, and packed kimchi scored highly on convenience. Frozen fried rice, retort, instant porridge, instant rice, RE meat, cereal, instant soup, and RE side dishes on consumption on a regular basis. Cereal, refrigerated foods, and RE side dishes laid emphasis on taste. Noodles, instant rice, cereal, ham, and RE side dishes focused on variety. Retort, RE meat, ramen, cereal, ham, and on the spot sandwiches looked to originality, while canned foods was recognized as ‘needing improvement’.

  • Centralized safety stock in a periodic replenishment system which consists of one central warehouse and m regional warehouse can reduce backorders allocating the centralized safety stocks to regional warehouse in a certain instant of each replenishment cycle. If the central warehouse can not monitoring inventories in the regional warehouse, then we have to predetermine the instant of allocation according to demand distribution and this instant must be same for all different replenishment cycle. However, transition of inventory level in each cycle need not to be same, and therefore different instant of the allocation may results reduced shortage compare to the predetermined instant of allocation. In this research, we construct a dynamic model based on the assumption of monitoring inventories in the regional warehouse everyday, and develop an algorithm minimize shortage in each replenishment cycle using dynamic programming approach.

  • Distributing information on the internet is common in our daily life. In the past, e-mail has been the primary choice of exchanging information, but instant messengers are gaining popularity abroad and domestically because of their immediate responses. Instant messaging has become the fastest growing communication technology in recent years. Instant messaging is effectively a chat room for two people. Users that have accounts with the same provider are able to send messages via computer in real time. Instant messaging has exploded into the business world as companies now utilize the technology for everything from interoffice communication to client/customer communication. In this paper, we propose a method of instant messenger system design for effective collaboration of statistical data collection.

  • As smart phones become more common nowadays, mobile instant messengers such as kakao talk and line are used as essential communication tools exchanging information between individuals. Also, the mobile instant messengers extend their use to business area beyond communication between individuals. This study is on how factors of mobile instant messenger such as perceived security, perceived privacy, perceived enjoyment and perceived interactivity affect business continual usage intention through perceived usefulness. The proposed model is based on Expectation-Confirmation Theory of Oliver and Technology Acceptance Mode of Bhattacherjee. For an analysis, 159 survey responses were collected from the office workers in Seoul and nearby cities, having experiences of mobile instant messengers. To validate the proposed research model, PLS analysis is performed with the valid 154 questionnaires. The path analysis results are as follows. First, perceived security has a positive effect on expectation-confirmation. Second, perceived enjoyment has a positive effect on perceived usefulness. Third, perceived interactivity has a positive effect on both perceived usefulness and expectation-confirmation. Fourth, perceived usefulness has a positive usefulness on satisfaction and continual usage intention of mobile instant messenger. Last, expectation-confirmation has a positive effect on perceived usefulness, and satisfaction has a positive effect on continual usage intention of mobile instant messenger. Since the mobile instant messenger may bring a pressure of work and a violation of privacy, it is necessary that the company provide a guideline for use of the mobile instant messenger and establish the in-house mobile instant messenger system.

  • In this paper, concerning the various advertising and policy advertising of the election with respect to whether to deliver a message to a large number of people, we design and implement an automative system what enables sending the text messages directly from the server to the client and also fast feedback is enabled by utilizing a number of operational programs to connect to the server. Therefore, we design and implement the automative communication system which enables delivering message to each user mobile terminal from a plurality of relay mobile terminals by utilizing the mobile instant messenger, not to deliver a message from the server to the mobile instant messenger user directly. In result of comparative analysis on the number of times of data transmission, this automative communication system utilizing mobile instant messenger shows the result that it enables transmitting five times per minute as it can copy and paste in the automation system regardless of the size of the data loading, otherwise in case of transmitting manually it show the result that the number of times of data transmission is reduced if the size of the data is larger.

  • 현대 사회에 있어서 신속하고 정확한 정보는 곧 수익증대의 중요한 요소로 자리 잡고 있으며 사회발전이 가속화 될수록 더욱 다양한 정보가 산출되고 있다. 그로인하여 광범위하게 분산되어 있는 정보의 추출은 매우 중요한 부분으로 부각되고 있다. 하지만 기존의 자료 집계 방법은 분산되어 있는 자료를 수집하기 위한 시간이 많이 소요되고 수집된 자료의 확인과정 및 통합 과정 또한 많은 시간이 소요되어 현대의 수많은 정보를 효율적으로 수용하지 못하고 있다. 이에 본 논문에서는 광범위하게 분산되어 있는 자료들에 대하여 효율적인 정보 추출을 제공할 수 있는 자료 집계 및 분석 시스템의 설계 및 구현 방안에 대하여 연구하고자 한다.

  • PC camera-based instant messenger have problems of video image break/delay and noise. The reason is caused by a composed problem that PC Camera is belong to the connected PC and operating in the PC. This research suggests an instant messenger that uses network camera connected to LAN instead of PC camera. Therefore, the instant messenger has a component that the camera is separated from PC. This research designs sequence diagram, video calls flow chart, and graphic user interface of the instant messenger. The instant messenger based on network camera provides high quality video calls service and makes it possible to call from a special remote site with real-time video image.

  • 인터넷 메신저는 네트워크를 통해 대화를 나누거나 데이터 등을 주고받을 때 가장 널리 쓰이는 통신수단 중 하나이다. 그러므로 디지털 포렌식 관점에서 메신저의 통신내역을 확보하는 일은 전화, 휴대폰과 같이 전통적인 통신내역을 수집하는 작업처럼 매우 중요하다. 하지만 메신저의 통신내역은 사용자 컴퓨터에 암호화되어 저장되거나 메신저 서버에 보존되기 때문에 의미 있는 데이터 수집이 쉽지 않다. 본 논문은 네이트온, 버디버디, 야후!, Mi3 메신저를 대상으로 사용자 컴퓨터에 저장된 통신내역을 복구하는 방법과 메신저 서버에 존재하는 통신내역을 열람하기 위한 인증우회기법을 제시한다.
