This paper discussed the factors that necessitated information networking, types of networks, benefits of information networking, library information networking and the University of Port 0Harcourt library network initiatives. Information networking is a process of communication, exchange of ideas, resource sharing and collaboration between individuals, organizations, institutions and libraries and it is facilitated by ICTs and the internet for improved accessibility. It has been brought about by information explosion, rapid advancement in information communication technologies, inadequate funding and increased demand for quality information. Networks can be classified into local, national, regional, and international networks and are formed to serve different categories of user communities. Benefits of information networking include resource sharing, on-line conferences and participation in programmes at distant centers, collaboration among scholars in different countries. Communication flow through the internet, social media, and electronic mail. Library information networking started with the interlibrary loan which has metamorphosed into library consortia in which groups of libraries partner to coordinate activities, share resources and combine expertise. The University of Port Harcourt Library network initiatives started with an e-granary (a CD ROM) and the establishment of a local area network. The library subscribes to more than 10 electronic databases. Information networking has greatly improved the sharing of resources in acquisition and dissemination of information resources since no single institution can acquire the overwhelming number of information resources in their various formats.

본 연구는 17대 대통령기록과 관련한 언론의 의혹들을 중심으로 문제의식을 더욱 확장하여 17대 대통령기록을 조사·분석하고, 그 결과를 바탕으로 대통령기록관리 체계 개선을 위한 방안을 제언하는 것을 목적으로 한다. 이를 위해 먼저 대통령기록관에 이관된 17대 대통령기록을 전체적인 시각에서 개관하고, '기록관리', '부속실', '치안'기능에서 생산된 기록을 정량적으로 분석하였다. 다음으로 '생산현황통보', 'e메일을 통한 기록 생산 및 기록 미등록', '핵심기록 및 전자·비전자기록'의 사례를 정량분석과 함께 실물 기록을 정성적으로 분석하여 17대 대통령기록의 성격을 진단하였다. 마지막으로 분석 결과를 토대로 대통령기록관리체계 개선을 위한 방안을 제시하였다.

이 논문은 상거래의 혁명이라고 불리 우는 EC에 대한 우리나라 대학생의 인식수준과 구매태도를 조사 분석한 것이다. 조사는 Kalakota와 Whinston의 ${\ulcorner}$EC소비자 구매단계 모형${\lrcorner}$을 중심으로 한 구매태도와 EC에 대한 전반적 인식수준에 초점을 맞추었다. 분석결과, (1) 제품검색 경로는 심마니나 Yahoo와 같은 전문검색사이트를 가장 선호하였고, (2) 인터넷 쇼핑대상 제품은 대체로 분산된 편이나 호텔 비행기 예약, 음반 CD/Tape, PC와 PC부품/software, 꽃 배달, 서적 등이 주종을 이루었고, (3) 구매가격의 범위는 $5{\sim}10$만원, (4) EC의 가격수준은 싼 것 같지 않다고 인식, (5) 결제시스템에 대한 불만, (6) 반품 교환 A/S에 대한 불신 등이 발견되었다. 이에 대한 마케팅시사점으로, 향후 EC를 이용하려는 기업은 분석개요에서 지적한 점들을 토대로 하여 ${\ulcorner}$EC고객의 본원적 복구${\lrcorner}$에 초점을 둔 마케팅전략을 개발해야할 것이다.

본 논문은 크기가 소형화된 광대역 기생 패치 안테나를 제안한다. 폭이 좁아진 주 패치의 두 방사 모서리부에 U자 형태의 기생 패치를 설계하여 안테나 전체 크기를 감소시키고, 주 패치와 기생 패치 사이의 E-plane 및 H-plane을 통한 electromagnetic coupling에 의해 광대역 특성을 얻는다. 안테나 방사 소자들의 전체 크기는 $18{\times}17.6\;mm^2$ 이고, 접지면과 유전체를 포함한 전체 크기는 $25{\times}30{\times}4\;mm^3$이다. 설계된 안테나는 FR4 유전체를 이용해 제작하였으며, 5.12 GHz와 6.08 GHz의 공진 주파수와 5.5 GHz 중심 주파수를 기준으로 27.3 %(1.5 GHz)의 대역폭을 갖는다. 측정된 안테나의 방사 패턴은 일반적인 마이크로스트립 패치 안테나와 유사하다.

This paper reports a method to use a wireless sensor network deployed in the field to real-time monitor soil moisture, warning when the moisture level reaches a specific value, and wirelessly controlling an additional device (LED or water supply system, etc.). In addition, we report all processes related to wireless irrigation system, including field deployment of sensors, real-time monitoring using a smartphone, data calibration, and control of additional devices deployed in the field by smartphone. A commercially available open-source Internet of Things (IoT) platform, NodeMCU, was used, which was combined with a 9V battery, LED and soil humidity sensor to be integrated into a portable prototype. The IoT-based soil humidity sensor prototype deployed in the field was installed next to a tree for on-site demonstration for the measurement of soil humidity in real-time for about 30 hours, and the measured data was successfully transmitted to a smartphone via Wifi. The measurement data were automatically transmitted via e-mail in the form of a text file, stored on the web, followed by analyses and calibrations. The user can check the humidity of the soil real-time through a personal smartphone. When the humidity of a soil reached a specific value, an additional device, an LED device, placed in the field was successfully controlled through the smartphone. This LED can be easily replaced by other electronic devices such as water supplies, which can also be controlled by smartphones. These results show that farmers can not only monitor the condition of the field real-time through a sensor monitoring system manufactured simply at a low cost but also control additional devices such as irrigation facilities from a distance, thereby reducing unnecessary energy consumption and helping improve agricultural productivity.

The ODR can be categorized into four distinctive types. First type is the asynchronous non-demeanour method. Second type is the asynchronous demeanour method. Third type is the synchronous demeanour method. Fourth type is the synchronous demeanour method. A typical example of the asynchronous and non-demeanour method is e-mail. The example of the synchronous and non-demeanour method is tele conference. The example of the asynchronous demeanour method is video recordings. The example of synchronous and demeanour method is video conference. The primary benefit of e-mail is to avoid the physical violence. But the costs of email is the lack of emotional aspects of disputants. The benefits of tele conference is ease of use, and reduces the negative aspects of face to face communication. but the costs are limitation of the exchange of written information. The benefits of video conference is the approximation of face to face communication by providing oral as well as visual communication. but it is insufficient to represent eye contact. The common limitations of ODR are as follows. First is the lack of human face. Second is the neutrality of arbitrators and mediators. Third is the authenticity of electronic document. Fourth is the digital divide across South and North and generations. Fifth is the cross-cultural communication. The development strategy of ODR is the training and education of arbitrators and mediators in the area of writing skill. Furthermore, it is necessary to supplement the weakness of email via diverse kinds of expressions to show emotions. Finally, it is necessary to train neutrals in the area of cross-cultural communication.

기존 선박 통신시스템은 위성통신을 이용한 음성, FAX, ISDN 등이 대부분으로 선박 해상관제 업무에 집중되고 있지만, 최근의 레저선박 통신시스템의 경우는 더 높은 품질의 스마트 통신 서비스 및 통신환경을 요구하고 있다. 기존 통신시스템을 활용하여 통신 환경을 실험한 결과, 선상에서는 위성통신이 가능하나, 밀폐된 선내에서는 위성통신을 중계한 음성통신만 가능하고 스마트 앱이나 이메일 사용은 불가하였다. 본 논문에서는 선상뿐 만아니라 선내에서도 음성, 문자, 이메일, 대규모 파일 전송, 해상관제 앱 실행이 가능한 통신시스템 구현을 제안한다. 본 연구를 통해 위성통신단말기와 스마트폰이 결합한 듀얼 복합 통신단말기와 선내에서도 대용량 이메일 및 스마트 앱 사용이 가능한 시스템을 구현하였다. 실험 결과 선박 어느 위치에서나 다양한 통신이 가능하였다.

모바일 분야가 과거 음성통화 중심에서 데이터통신 서비스(SMS, E-Mail, 웹 서핑 등)를 거쳐 스마트폰 기반의 '생활편의' 서비스로 진화 중이다. 최근 전 세계 도서출판 시장 규모 통계에 따르면 전자책의 비중은 늘어나고 있는 반면 종이책의 비중은 줄어들고 있는 것으로 보인다. 종이책의 발전으로 수많은 전자책이 시중에서 판매되고 있으나 종이책에 능동형 통신기능을 제공하는 NFC 기반의 모바일 환경을 융합한다면 전자책이 가지고 있는 단점을 보완하고 보다 다양한 응용분야에서 요구하는 사항을 만족시킬 수 있다. 따라서 본 논문에서는 NFC 기반 모바일 교육용 음성동화책 어플리케이션을 설계 및 구현하기 위해 관리 대상의 정보를 장치에 저장하는 것이 아닌 서버에 저장하는 방법을 통해서 개발의 효율성 및 유지 보수성을 고려한 NFC 기반 모바일 교육용 음성동화책 어플리케이션을 구현하였다.

Previous studies on user training have largely focused on assessing models which describe the determinants of information technology usage or examined the effects of training on user satisfaction, productivity, performance, and so on. Scant research efforts have been made, however, to examine those effects of training by using theoretical models. This study presented a conceptual model to predict intention to use information technology and conducted an experiment to understand how training for computer skill acquisition affects primary variables of the model. The data were obtained from 32 student subjects of an experimental group and 31 students of a control group, and the information technology employed for this study was a university's electronic mail system. The study results revealed that attitude toward usage and perceived behavioral control helped to predict user intentions; outcome expectations were positively related to attitude toward usage; and self - efficacy and perceived behavioral control. The changes in those variables suggest more causal effects of user training than other survey studies.
