Life cycle assessment was carried out to evaluate the environmental values of dimethylas a diesel alternative fuel with the assumption of dimethyl ether production from natural gas via synthesis gas. The whole life cycles from raw material acquisitions to the final usages of diesel and dimethyl ether were involved in the assessment. Inventory analysis showed that the most significant environmental impacts came from resource depletions and air emissions. Impact assessment revealed that dimethyl ether was environmentally better in the aspect of human health and ecosystem quality but worse in resource depletions compared with diesel fuel. Suggestions for environmental improvement of dimethyl ether as a diesel alternative fuel were prepared based on the assessment results.

POS(Point of Sales) 시스템이란 매출을 발생시키는 유통업체 금전출납계에 설치되어 매장에서 발생하는 판매시점의 모든 정보를 실시간으로 수집, 가공, 처리, 저장하여 각 부문별 정보를 분석, 평가, 종합 할 수 있는 상품의 판매 결과를 기록하는 시스템이다. 다양한 업종에서 POS SYSTEM(주문 관리 시스템)의 도입으로 보다 효율적인 업무를 처리하고 있지만 기존의 획일적인 POS 시스템들은 고가의 전용장비를 이용하고 물리적인 제약으로 인하여 비용, 규모, 구성면에서 적합하지 않다. 본 논문에서 제안한 유비쿼터스 기반의 ZigBee 를 이용한 시스템은 휴대단말기의 무선제어 기술과 연계를 통해 여타 기술 대비 편리성, 재사용성 및 시스템 구축 비용의 절감을 통해 시스템의 효율성을 높일 것 이다. 또한 네트워크 단축 경로 검색 기술과 양방향 통합 리모콘 설계와 같은 유비쿼터스 기반의 ZigBee 기술을 통해 시스템의 부가가치를 높이는 등 산업에 보다 나은 발전을 가져오게 될 것으로 전망된다.

We suggest a new way of specifying the co-evolution of product and process technologies, and integrating it into one of the well-received technology intelligence tools - a technology radar. Cross impact analysis enables us to identify the core technologies of product-process co-evolution. Combining expert judgment with its results, we can clarify the technological co-evolution trajectory with mainstream as well as emerging core technologies. Reflecting these in the assessment process of a technology radar, we could improve reliance of the technology assessment process and technology portfolio. From the academic perspective, our research provides a point where the co-evolution theory encouners technology intelligence methods. Practically, strategic capability of future-preparedness and strategic management could improve by adopting our method based on our example of co-evolution of semiconductor product and process technologies.

Recently, ubiquitous computing technology becomes available to develop advanced electronic commerce：u-commerce. Hence, it is the very time to perform feasibility analysis in applying ubiquitous computing technology, especially estimating economical value of the on-going technology. Hence, the purpose of this paper is to propose a financial value estimating methodology in performing feasibility test on ubiquitous computing technology. To do so, Black and Scholes model is basically adopted. To show the feasibility if the idea proposed in this paper, actual case study through focused group interview with those who are actually performing on-going ubiquitous computing projects. As the result, we validated the possibility of applying Black-Sholes model to assessing feasibility analysis for ubiquitous technology development with the price of call option, volatility, and the comparison with other similar technologies.

기후변화-수자원 적응과제들의 성공적인 수행과 결과물의 활용을 위해서는 안전행정부, 환경부, 농림축산식품부 등 물관련 정부부처간의 긴밀한 협조체계가 이루어져야 할 것이다. 이를 위해서는 (1)안전행정부의 재난관련 방재패러다임 전환 및 위기관리 체계강화를 위한 추진과제(자연재해 지자체 방재시스템), (2)환경부의 기후변화에 따른 물환경관리 대책 추진과제(비점오염, 수질, 수생태, 습지), (3)농림축산식품부의 농업수자원 및 산림자원 확보 추진과제(농업용수, 산림재해) 등의 진행상황 및 결과의 공유체계 및 공동활용을 위한 채널구축이 필요하다. 포럼에서의 의견으로서, 타분야 특히 산업일선에서는 이미 기후변화에 따른 적응정책과 더불어 관련기술의 개발이 진행되어 우리 수자원분야는 많이 늦은 감이 있다는 지적, 그리고 제시된 기획과제 중에서 제4세부과제인 수자원의 가치를 평가하는 기술개발이 매우 중요하다는 언급이 많았다. 이에 저자들은 수자원의 가치를 높이기 위해서는 농업 그리고 에너지 분야의 전문가들과의 협력연구(Water-Food-Energy Nexus)를 통하여 세 분야의 통계기반, 정보공유, 융합가치 등의 제반연구는 매우 중요한 미래과제라고 강조하였다.

The development of information technology provides us with more useful information but it arose to protect such information from inappropriate users. In the course of analyzing and managing the risks associated with information, it should be needed to accurately measure the value of information. We try to consider the contingent valuation method for this purpose. The contingent valuation method which is used to assess the value of public goods or nonmarket goods makes an statistical estimation for the willingness-to-pay. We show with an example how we can estimate the value of information by calculating the amount we are willing to pay the value of information that exists on the information system. Calculation is carried out by using R.

A necessity increases but since a many manpower and the budgets are insufficient for archiving all digital resources the digital archiving at the science information center or the digital library has to be successively processed according to the priority. Therefore, in this research, whether it has to archive among digital resources which Korea Institute Science and Technology Information(KISTI) hold around any kind of contents or not makes analysis and valuation around the value for use. The priority evaluation plan that can become the system analysis and reflection based on this automatically tries to be proposed.

Currently, the domestic nursing information system software products are being developed competitively with the participation of many companies, generating quantitative development with high value added. However, it is true that the study that concurrently adds qualitative enhancements to such quantitative development has been inadequate. In order to secure international competitiveness in the field of nursing information system software, it is necessary to establish quality requirements on this system, and along with it, establish an evaluation system on the nursing information system software products. The purpose of this study is to analyze the accompaniment and technology of the nursing information system, and by identifying the requirements, establish test and evaluation system of the said system.

고도로 발전하고 있는 건설산업과 소비자의 요구가 점차 세분화 되면서 객관적인 평가기능을 갖추고 있는 품질경영시스템이 지난 1992년부터 건설업계에 도입됨에 따라 건설업계는 시공의 표준화가 정착되어 가는 중이다. 최근에는 환경 및 안전.보건에 대한 관심이 높아지면서 건설업계는 환경.안전보건경영시스템 획득으로 기업경영의 우수성을 객관적으로 인증 받는 추세이다. 설비건설업계의 경우 환경경영시스템(ISO 14001)을 인증 받은 업체가 36개사, 안전보건경영시스템(K-OHSMS 18001)은 2개사, 안전경영시스템(KOSHA 18001, 건설업)은 3개사가 인증을 받는 등 아직 초기단계에 있으나 점차 확대될 전망이다. 환경.안전보건경영시스템을 인증 받을 경우 금융기관의 기술신용평가시 가산점 부여, 시공능력평가시 가산점 부여, 기술비 세액공제, 인증획득 자금지원, 융자신청시 가산점 부여, 기업실무자 교육비지원 등의 혜택이 주어지나, 무엇보다도 지속적인 관리로 업무의 질적 향상과 체계적인 관리를 통해 한 단계 업그레이드 가능한 것을 장점으로 꼽을 수 있다. 본지는 환경·안전보건경영시스템 인증 절차 및 인증시 효과에 대해 알아본다.
