The purpose of this study is to survey on the engineer's sense of value. For this, we analyzed the ethic code of the engineer relation groups and executed the survey of consulting committee. The subjects of analysis were six associations related to engineer, and analysis of the ethics was done on the basis of 'four levels of engineer's ethics or sense of value'. The subjects of survey were 57 professions. The ethic code shows the most important engineer's sense of value is dignity maintenance, development of individual and social welfare as well as public service. The survey shows the most important sense of value when engineer make decisions at the present is practicality and economical efficiency. And it shows the most important sense of value when engineer make decisions in the future is practicality and economical efficiency.

The exclusive bus lanes in the Yeongdong Expressway were implemented in the Singal to Yeoju section in 2017, but the capacity of both exclusive bus lanes and general-purpose lanes of the Yeongdong Expressway decreased and the travel time increased, reducing it to the Singal to Deokpyeong section. Therefore, it is necessary to increase the efficiency of exclusive bus lanes to revitalize public transportation and improve environmental problems. This study calculated the willingness to pay and the social benefits of permission for Green cars to drive on exclusive bus lanes in Yeongdong Expressway. A survey was conducted on two groups of Green car users and Expressway users, and the willingness to pay was estimated using the CVM method. As a result, the average WTP of Green car users were estimated to be 218.7(won/km·person), and that of Expressway users were estimated to be approximately 235.5(won/km·person). The direct benefits were estimated to be approximately 7.9 billion won for Green car users, and 8.5 billion won for Expressway users in 2019. Finally, the value of time saving was estimated to be approximately 8.0 billion won.

In implementing transportation projects, benefits have been estimated using conventional benefit components. However, these components have a lot of assumptions and limitations for benefit estimations and thus it seems to be difficult to obtain values of parameters as well as to overlook benefits of non-market goods in calculation process. In other words, current benefit estimations are considered that can be solely measured by directly depending on traffic volumes. Existing economic analysis do not reflect the full benefits, including direct and indirect of the project implementations. To illustrate this fact, bicycle road construction can result in various functional benefits, including improved quality of life, balanced regional development, and good scenery composition. These benefits can not be explained with conventional economic analysis. The objective of this research is to estimate valuation of bicycle road construction using Contingent Valuation Method (CVM). CVM can evaluate user's direct willingness-to-pay as well as maximize bicycle utilization with balanced regional development. This research used the coastline bicycle road construction project for example. The proposed method can be well calculated or estimated benefits for non-market goods of bicycle road constructions using CVM.

외해로부터 해안선부근으로 이동하는 파랑은 해저협곡 및 대륙붕과 같은 해저지형의 변화, 방파제와 같은 해안구조물과의 상호간섭 및 파랑상호간의 비선형효과 등에 의해 굴절, 회절, 천수 및 쇄파 등과 같은 변화를 경험한다. 파랑변형의 원인이 되는 여러 변화 중에서 흥미 있고 연구할 가치가 있는 물리적 현상중의 하나는 Bragg 반사이다. (중략)

맥주의 한sod 혼탁방지용으로 널리 사용되고 있는 papain을 미생물 효소로써 대치할 목적으로 토양에서 분리한 148주의 균주가운데서 Bacillus 속이라고 추정되는 한 균주를 선택하여 효소를 생산하였다. 이 효소는 제탁 능력에 있어서 시판의 protesal에 비등하며 저장시에는 pH7-8, 온도 $35^{\circ}C$ 이하에서 안정성이 확인되어 충분히 실용가치가 있는 것으로 본다.

일부 소프트웨어들의 상품 가치의 판단은 과거 기능위주에서 사용자 중심의 디자인적 요소들 만족여부에 결정되어지고 있다. 그러나 많은 소프트웨어가 시스템 공학적 개발에 중점을 두고 개발되어지고 있고 사용자 및 사용자 환경을 분석을 통한 디자인적 개발에 중점을 두고 있지 않는 실정이다. (중략)

동물성식품이라 함은 축산식품과 수산가공품을 말하게 되며 대부분의 단백질식량은 동물성식품에 의하여 확충되고 있다. 일반적으로 동물성식품은 그 영양적 가치와 맛으로 소비자의 애호를 간고 있으며 많은 통계자료들은 국민소득의 증대에 따라 동물성식품의 소비가 급증하는 사실을 나타내어주고 있다.(중략)

이글에는 의료용 특히 의료계층용에 사용되는 바이오센서의 원리 및 응용예를 간략히 소개하였지만, 바이오센서레 관한 연구는 매우 광범위하게 진행되고 있으며 소형화, 안정성 등의 몇가지 문제점이 해결되면 차세대의 고부가가치 창출산업으로의 기대가 매우 크다. 또한 현재는 생물과 전자공학이 결합한 bioelectronics의 시대에 돌입되었기 때문에 앞으로의 발전은 무한하리라 생각된다.
