Environmental management systems offer a set of management tools and principles that can help integrate environmental concerns into daily business practices. Such systems have been in existence since the 1980's. This research identifies the firm's implementation of environmental management that is the most and least popular for managing the environmental management such as 3R's, EM, EMS, environmental awareness. This article investigates the differences of managing to environmental issues of firms between Korea and U.S. The research results suggest that the U.S. firms control of 3R's, EM and EMS better than Korea's, while Korean firms have higher environmental awareness than U.S. firms.

본 연구는 미국의 지방자치적 브로드밴드 사업동향을 통해 바람직한 u-City 사업의 추진에 필요한 접근방향을 살펴보고자 하였다. 즉, 미국의 추진사례를 바탕으로 우리나라에서 브로드밴드 사업 추진시 사업운영모델을 만들거나 국내 u-City에서의 적용 가능한 비즈니스 모델에 대한 시사점을 도출하고자 하는 것이다. 미국의 사례를 통해 국내u-City에 고려할 수 있는 부분으로서 민관합작(Pirvate-Public Partnership) 모형에대한 부분을 들 수 있다. 미국의 PPP 모형을 통해 지방정부는 고액의 유지보수 비용문제와 사고발생시 책임소재 문제를 해결할 수 있는 길을 마련하였다. 또한, 거주민에게는 경쟁을 통한 저렴한 가격으로 서비스를 제공하고, 저소득층과 불리한 여건의 거주자들에게 혜택을 제공함으로써 디지털 디바이드 문제를 줄일 수 있었다. 제도적인 면에서 한국과 미국이 브로드밴드 정책에 있어서 차이를 나타내고 있지만, 정책의 변화로 인해 국내에서도 지방자치적 브로드밴드 문제가 논의될 것에 대비하여 준비할 필요는 있을 것이다. 또한, 향후 직면할 문제점들을 사전에 예방하고 대비하는 데 도움이 되었으면 한다.

u-Park는 친환경적 USN과 u-IT 기술을 토대로 자원 및 시설물들이 지능화되고 그에 관련된 정보가 통합적으로 관리되는 공원이다. u-Park 관리시스템의 도입을 통해 관리효율성 증대를 도모하고 과학적 수용력 관리를 실현하기 위해서는 국립공원관리자가 새로 도입되는 u-Park 관리시스템을 수용할 수 있어야 한다. 관리자의 u-Park 관리 시스템 기술수용과정을 규명하기 위해 기술수용모델(TAM) 구조방정식을 설정하였다. 5개 산악형 국립공원에 근무하는 국립공원관리공단 직원 176명을 대상으로 설문조사를 실시하여 자료를 수집하였다. 분석결과 TAM 구조방정식의 설명력은 55.2%이며, u-Park 관리시스템이 현재 업무 내용과 관리자의 업무 처리 방식에 호환되는 정도가 관리자의 기술수용에 가장 큰 영향력을 미치는 것으로 나타났다.

The researches on cyclical patterns of R&D investment has a long history in developed economies since the Schumpeterian hypothesis that long-term productivity-enhancing innovative activities increase during recession. But in Korea the cyclical patterns of R&D investment is one of the unexplored academic areas. Unlike theoretical explanation of R&D's cyclical pattern, empirical results has shown that R&D investment is procyclical to business cycles in developed countries. This paper investigates whether Korean R&D investment show procyclical or countercyclical pattern to business cycles. The empirical results show that Korean R&D investment in private area is procyclical to business cycles with statistical significance, which confirms the credit-constraint theory's prediction, while public area's is not sensitive to them. Public R&D investment has long-term investment characteristics and can be utilized to stabilize procyclically-fluctuating private R&D investment.

The Evolution of Workflow Managment consists of rhe automation of business procedures or "workflows" during which documents, information or tasks are passed from one participant to another in a way that is governed by rules or procedures. Workflow technologies have evolved from image management system, document management system, relational or object database systems, and electronic mail system. Workflow Management system has the benefits to improve better efficiency, process control,flexibility, business process. Automation of many business processes results in the elimination standdardizing working methods. Consistency in the processes leads to greater predictability in levels of response to customers and software control over processes enables their re-design in line with changing business needs, In this present study, we implement Electronic Approval System which is a kind of Workflow Management system using static and dynamic flow control information on the web environment.

A Technology Roadmap (TRM) is extensively used as a tool to manage activities of researching and developing technologies and products that can help a business achieve its goals. However, most of past studies on TRMs have limited themselves to developing in a single product or a single industry level. Few research studies have examined how TRM are used for convergence products and services for future development. The aim of this chapter is to introduce a TRM development methodology for u-City technologies and to consider its possible application at the R&D program level in Korea. This research suggests ways to develop a TRM in u-City development by segmenting u-City technologies, projecting TRM for each technology and designing TRM templates for evaluating both current and future technologies. In addition, the study further highlights to prioritize which technology is favorable for the implementation based on its economic feasibility and technological maturity.
