Information technology has changed the human life as well as the societal and economic paradigm. New office environments have been proposed to cope with emerging changes and to support working performances by reducing costs of office operation and business. Recently, office environments have adopted ubiquitous computing with a focus on collaboration to promote real-time enterprises. They become equipped with various mobile devices and pervasive technologies in wireless networks. This study aims to propose a direction for the adoption of mobile and pervasive computing on the new office environment. We investigate relate works and analyze new office types including mobile offices, telework centers and home offices. Using a customized questionnaire, the current conditions of the office environments and officers' demands were investigated and analyzed. In the end, we propose the direction for a ubiquitous office environment with a focus on two attributes, ubiquity and mobility. This research will be a basis for the development of ubiquitous offices that support the professionalism of works in practices.

본 연구의 목적은 위치기반서비스(Location-Based Service: LBS)에서 관계 품질과 L-로열티에 미치는영향에 대해 검증하는 것이다. LBS, 관계 품질, L-로열티에 관한 이론적 배경을 바탕으로 연구모형 및 가설을 설정하였다. 본 연구에서는 위치기반서비스 이용자들을 대상으로 설문지를 배포하였다. 연구결과, 첫째, 개인화, 지각된 가치는 몰입에 정(+)의 영향을 미치는 것으로 나타났고, 지각된 위험은 몰입에 부(-)의 영향을 미치는 것으로 나타났다. 둘째, 개인화, 편재성, 지각된 가치는 만족에 정(+)의 영향을 미치는 것으로 나타났고, 지각된 위험은 만족에 부(-)의 영향을 미치는 것으로 나타났다. 마지막으로, 몰입과 만족은 L-로열티에 정(+)의 영향을 미치는 것으로 나타났다. 본 연구는 위치기반서비스에서 관계 품질과 로열티를 향상시키고 충성도 높은 고객을 확보할 수 있는 다양한 시사점을 제공할 수 있을 것이다.

본 논문은 황우석 교수의 2005년 5월 배아줄기세포 연구성과 발표에 대한 인터넷상의 공론이 어떻게 이루어졌는지를 통해 일반 공중의 배아복제에 대한 이해를 연구한다. 인터넷 공론에 대한 분석은 일반화의 어려움은 있지만 질적 연구의 장점이 있다는 점을 분명히 하면서 사례연구를 하였다. 5월 20일 주요 신문은 연구성과의 세계적인 의의와 더불어 난치병 치료를 위한 연구로 자리매김을 만들었으며 윤리문제를 부각하는 데서 약간의 차이를 보였다. 그런 영향으로 인터넷상에서는 훨씬 더 분명한 형태로 환호하는 분위기를 보였다. 네이버 게시판은 연구성과에 대한 열광과 더불어 윤리문제제기를 비판하는 경향을 띠었고 연구의 정당성을 묻는 민주노동당에 대해서는 보다 애국주의적 국가주의적 근거에서, 가톨릭의 반대성명에 대해서는 배아는 생명이 아니며 낙태 등이 일상화된 현실적 근거에서 비판되었다.

Radio Frequency Identification(RFID) is rapidly growing the attention of many firms as a care technology for their businesses. As RFID moves into the mainstream, it replaces the standard barcodes that is used to identify and track products for a long time. With the intention of gaining competitive advantages, some firms have started the changeover to RFID technology while others have been disinclined to adopt it. Thus, this study examines firms as an attempt to identify key organizational characteristics driving the ear1y adoption and successful implementation of RFID. Results from 228 adopting organizations show Organizational Needs(Ubiquity and Performance Gaps), Technological Factors(Perceived Benefits and Perceived Cost Savings) and RFID Reduced Risk have a significant influence on RFID initiation. In addition, Trust Factors(Institutional Trusts and Inter-organizational Trusts) have a significant impact on RFID Reduced Risk. Finally, Organizational Readiness(Financial Resources and Technological Knowledge) have a significant influence as moderating effects between RFID initiation and adoption. The implications of the findings propose a new theoretical framework for the future IT/IS adoption study and offer suggestions for RFID researchers and practitioners in the development of the technology.

유비쿼터스 컴퓨팅이란 마크 와이저의 주장처럼 급진적이지 않으며 포괄적으로 유비쿼터스 컴퓨팅을 정의할 수 있는 적절한 정의로 판단된다. 각국의 실태에서 미국이나 유럽에서 실시되고 있는 프로젝트는 전반적으로 유비퀴터스 컴퓨팅 인프라 구축을 위한 연구와 사물의 지능화, 인간-컴퓨터 상호작용 연구, 공간의 지능화 등을 목표로 반면 일본은 어디서나 컴퓨터의 능력이 발휘되는 네트워크의 편재화를 위한 연구가 중심을 이룬다. 유비퀴터스 컴퓨팅 연구는 컴퓨터 과학의 특정 분야에 국한된 것이 아니라 사회, 경제, 윤리, 법 등 다양한 측면에서 연구되고 있으며, 국가의 적극적 지원을 기반으로 한다. 유비쿼터스 컴퓨팅이 다양한 센서를 통해 정보를 받아들이고, 판단하며, 커뮤니케이션 기술을 등을 제시하였다. 이를 근거로 유비쿼터스 컴퓨팅의 발전모델을 제시하였으며 진화과정에서 정형화된 가치시스템에 한계가 있으나 5가지 유형의 비즈니스모델이 나타날 것으로 전망한다.

In this study, a multilevel visible light communication (VLC) system based on resistor ladder circuit is designed to transmit medical data. VLC technology is being considered as an alternative wireless communication due to various advantages such as ubiquity, license free operation, low energy consumption, and no radio frequency (RF) radiation characteristics. With VLC even in places where traditional RF communication (e.g., Wi-Fi) is forbidden, significant bio-medical signal including the electrocardiography (ECG) and photoplethysmography (PPG) data can be transmitted. More lives could be saved anywhere by this potential advantage of VLC with a fast emergency response time. A multilevel transmission scheme is adopted to improve the data capacity with keeping simplicity, where data transmission rate can increase by log2m times (m is the number of voltage levels) than that of conventional VLC transmission based on on/off keying. In order to generate multi-amplitudes, resistor ladder circuit, which is a basic principle of digital to analog convertor, is employed, and information is transferred through LED (Light-Emitting Diode) with different voltage level. In the receiver side, multilevel signal is detected by optical receiver including a photo diode. Then, the collected data are analyzed to serve the necessary medical care to the concerned patient.

The habitual rooms and other structures related to everyday life are almost always grouped around the courtyard and together make up a house. There are many kinds of variety in types of courtyard houses depending on location, composition, allocation and relationship with inner space of the house. Every type of courtyard house accumulates many factors, which are social and economic circumstances, weather and geographical conditions. They are still well harmonized with life style and weather conditions in each area and basic unit of city organization. A courtyard can be shown as a place for everyday conversation like a community. Everyday space is the connective tissue that binds daily lives together, amorphous and so persuasive that it is difficult even to perceive. In spite of its ubiquity, everyday space is nearly invisible in the professional discourses of the city, like everyday life. Therefore Courtyards are special places that are outside yet almost inside, open to the sky, - a microcosm which gives relief to the inner rooms, gives the inhabitants a sense of ease and calm, and the feeling that they have their own piece of sky to use and protect them. This research will explore a variety of space use and dwelling types through courtyards based on field research and design projects.

The purpose of this research is to identify what factors influence a customer satisfaction and re-purchasing intention and to identify if customer's Intentions are different between a mobile shopping mall and Internet Shopping mall. To perform empirical analysis for the mobile shopping mall, this research reapplied the factors of Parasuraman et al.[77] in a Internet shopping mall, including reliability, reactivity, tangibility, and this research also applied the factors of a mobile properties, including ubiquity, localization, instant connectivity. The empirical results of this research indicate that all hypotheses in our model are significant; However, the factors of a mobile properties negatively. The results of a analysis indicate that the mobile properties in a mobile shopping mall are not significant yet. and customer's recognition in both mobile shopping mall and Internet shopping mall are the similarity. In Conclusion, with the rapid growth of the Mobile Shopping mall market, many mobile shopping mall researches based on customer's Intentions must be published. Therefore, this research will be the foundation of these researches.

This study aims to investigate factors affecting the intention of continuous use of O2O service by referring new media adoption theory and value-based acceptance model for movie ticketing services. For this study, a questionnaire survey was conducted for users of tickets ticketing service of the cinema online (including mobile) within the last 6 months. A total of 500 copies was collected and 404 copies were analyzed excluding 96 copies because of errors. As a result of the analysis, the ease of use and service ubiquity has a positive effect on perceived functional value and perceived emotional value, and usability has a positive effect on perceived functional value. Compatibility and trialability has a positive effect on both perceived functional value and emotional value. Previous experience has a positive effect on both perceived functional value and perceived emotional value, and inertia has negative effect on perceived functional value. Finally, the perceived emotional value has a positive effect on the intention to continuous use, but perceived functional value appeared to have no significant effect. This study shows a theoretical implication for new technology-based services such O2O. It was suggested to establish a practical marketing strategy and help to activate the O2O service field.
