The Korean government considers expanding the WtE share of total energy from 1% to 5% by 2020 through research and development (R&D) in waste-to-energy (WtE) technologies. This study attempts to measure the external benefits of investing in R&D in these technologies. To this end, a contingent valuation (CV) is employed. More specifically, a 2016 national survey of randomly selected 1,000 households was carried out across the nation to gauge the willingness to pay (WTP) for the investment. One-and-one-half-bounded dichotomous choice question was used in the CV survey, and the spike model was applied to dealing with zero WTP responses. The mean yearly WTP is estimated to be KRW 4,175 (USD 3.57) per household, which is statistically significant at the 1% level. Expanding the value to the entire nation translates into an investment of about KRW 79.1 billion (USD 67.6 million), which can be interpreted as the annual external benefit of the R&D investment in WtE technology.

Science & Technology(S&T) is the most important thing to attain competitiveness in the 21st century, Our traditional S&T policies have been focused on hardware infra structure. we should consider software of S&T to enhance effectiveness. S&T should be had a correct understanding method of the creation for S&T culture. It implies that S&T policy in the 21st century should consider nonmaterial factors which include social, human, environmental and culture. Under this background, The purpose of this paper is to seek new S&T policy in the 21st century. Therefor this paper deals with how we can prepare for the future S&T policy and classify the change of S&T policy of Korea and analyze the characteristic of each phase. This paper argues that all actors (for example, S&T personnel, corporate using S&T, general public) should participate in the process of S&T innovation since the 21st century is the generation of the general public S&T. Also this paper presented the expanded S&T policy Right S&T policy could leads to diffuse right S&T culture. Diffusing S&T culture could accomplish expanded S&T policy which was considered phases of culture and welfare.

본 논문은 Carlsson and Stankielvicz(1991)에 의해 처음으로 소개된 기술시스템(Technological Systems; TSs) 의 개념을 발전시키고, 이를 우리나라 평판 프린팅 기술에 적용하였다. 특히 평판 프린팅 기술이 생산 공정기술로서 차세대 기술인 생명공학기술, 정보기술, 환경기술, 나노기술 등과 결합하면서, 하나의 기술시스템으로 창출 및 진화되는 동태적 과정을 분석하였다. 연구결과, 평판 프린팅 기술이라는 특정기술에 초점을 맞춘 기술시스템 접근방법이 국가혁신시스템, 지역혁신시스템, 산업클러스터 등 기존의 접근방법들이 추구하는 정책 목표를 보다 효과적으로 달성시킬 수 있음을 보이고, 이를 하나의 대안적 정책개념으로 제안하였다.

여행지에서 제공하고 있는 스탬프 투어링 서비스는 여행객들에게 특별한 기념이 되어주고 있지만, 스탬프를 받기 위한 장소를 찾기 어려운 점과 여행지의 주변 정보를 얻기 위해서는 여행자의 별도의 노력이 필요하다는 단점이 있다. 이러한 문제를 해결하기 위해 유명 관광지 및 추천 명소 등에 NFC 태그를 설치하고 간단한 태깅만으로 스탬프를 수집할 수 있는 어플리케이션을 제안한다. 또한 이 어플리케이션에 저장되는 정보와 평가를 이용해 사용자별 맞춤 여행 코스를 제공하고 사용자가 좀 더 편리하고 재미있는 여행을 즐길 수 있도록 돕고자 한다.

This paper explores the role of entrepreneurship education in a modern economy and how the government, academic, and nonprofit sectors in the United States have responded to this growing field. There are several sectors that play important roles in the entrepreneurship education landscape in the United States. Over the past decade, there has been increasing participation of Federal and state governments. This recent trend suggests the field may be increasing in maturity and legitimacy, showing promise for expanding the reach of entrepreneurship education programs. Programs sponsored by nonprofit organizations and private foundations complement government initiatives and display an effective means of leveraging knowledge and resources across the relevant sectors. Thus, new initiatives, whether initiated by government or academia, should learn from the successes of this sector as well as be carefully considered within the context of existent programs and services. Nonetheless, the potentially dynamic environment of the entrepreneurship education field in the United States offers a specific opportunity to leverage the experience in mentorship activities at the post-secondary education to address a possible gap in these activities at the secondary education level.

This paper explores the determinants of the innovation impact of publicly funded R&D projects along three broad dimensions, namely project, firm and market-related factors. In addition to these factors we examine the attributes of the research result per se and aspects of the commercialization process. The observations from empirical and qualitative analyses are based on R&D projects funded by the Fifth and Sixth Research Framework Programmes of the European Union. Firm size, prior experience, innovation culture, the nature of the project itself, explicit intension to commercialize, consortium management and strategy are the factors with the strongest effect on project success, defined in terms of product/process innovation and/or technical knowledge creation. The paper provides important implications for the organization, objectives, and management of public programmes that fund R&D and for project and participant selection.

The existing underwater vehicle controller design is applied by linearizing the nonlinear dynamics model to a specific motion section. Since the linear controller has unstable control performance in a transient state, various studies have been conducted to overcome this problem. Recently, there have been studies to improve the control performance in the transient state by using reinforcement learning. Reinforcement learning can be largely divided into value-based reinforcement learning and policy-based reinforcement learning. In this paper, we propose the roll controller of underwater vehicle based on Deep Deterministic Policy Gradient(DDPG) that learns the control policy and can show stable control performance in various situations and environments. The performance of the proposed DDPG based roll controller was verified through simulation and compared with the existing PID and DQN with Normalized Advantage Functions based roll controllers.

In smart grid, electricity consumption data may be handed over to a third party for various purposes. While government regulations and industry compliance prevent utility companies from improper or illegal sharing of their customers' electricity consumption data, there are some scenarios where it can be very useful. For example, it allows the consumers' data to be shared among various energy resources so the energy resources are able to analyze the data and adjust their operation to the actual power demand. However, it is crucial to protect sensitive electricity consumption data during the sharing process. In this paper, we propose a fine-grained access control scheme (FAC) with efficient attribute revocation and policy updating in smart grid. Specifically, by introducing the concept of Third-party Auditor (TPA), the proposed FAC achieves efficient attribute revocation. Also, we design an efficient policy updating algorithm by outsourcing the computational task to a cloud server. Moreover, we give security analysis and conduct experiments to demonstrate that the FAC is both secure and efficient compared with existing ABE-based approaches.
