Socially-oriented R&D programs aimed at solving societal problem rather than scientific and industrial fruits have started recently. Societal problem is recognized as dilemma since this problem related to various stakeholders. And this is not solved with single program and needed long-term process. So the perspective of socio-technical system transition including technological and institutional change is needed. This paper suggests policy implication of Socially-oriented R&D programs from socio-technical system transition perspective. 'Transitioning of Socially-oriented R&D program' is the key concept of restructuring the program for the system transition. The establishment of multi-layer transition governance and the transition vision-making and transition experiment planning are the key process of transitioning the R&D program. This paper suggests the ways and issues of implementing this process in Socially-oriented R&D program.

This study deals with the changes in the government-funded research institutes (GRI) in terms of 'responding to social challenges and turning to the institutes that are pursuing sustainability transition'. The newly established societal problem-solving R&D projects in GRIs are core experiments for the transition. In order to discuss about the prospect of transition of GRIs, this study used focus group interview approach. In the interview, the GRIs's stance on the societal problem-solving R&D projects, and its process, problems and the policy direction had been discussed. It is suggested that the necessity of transition is discussed and transition experiments are proceeding on a small scale, but experiments are still underway in the existing framework. In order to facilitate the transition in GRIs, it is necessary to carry out the experiment and the vision making work from the inside the GRI.

Sustainability has already become one of the most important innovation policy agendas in many countries. Korea has tried to emulate this global trend in various forms, unfortunately with little success. A very strong tradition of centralized administration in Korea has meant that local communities and municipalities have remained more or less passive in tackling their own sustainability issues and problems. In recent years, with the impetus of huge democratization attempts in Korea since the late 1980s, there have been some local attempts to remedy these imbalances since the early 2000s. A series of local experiments to try and test green alternatives against the very hostile environment have been implemented, with varying degrees of success. This study analyzed cases of transition experiment to sustainable socio-technical system such as MUSIC project, Low Carbon Green Village and Citizens' Sunlight Power Stations. To draw politic meanings for sustainable socio-technical system, these content, process of conversion and feature were examined.

현재 우리나라 혁신시스템은 기존의 성장 및 기술공급 위주의 발전전략이 한계를 노정하면서 새로운 전환기를 맞고 있다. 이에 새로운 혁신 경로 창출을 위한 과학기술 ICT 정책 패러다임 전환은 물론 지속가능한 에너지, 농업 농촌 등 다양한 영역에서의 시스템 전환이 필요한 상황이다. 이를 위해서는 과학기술 ICT와 에너지 환경 등 관련 분야 간의 연계 통합은 물론, 기술이 활용 확산되는 현장이나 사회, 사용자의 이해가 더욱 중요해진다. 리빙랩은 사용자 참여를 기반으로 하는 새로운 혁신모델이자 지속가능한 시스템 전환의 니치 실험으로서 최근 유럽을 중심으로 부각되고 있다. 본 연구에서는 과학기술 ICT가 에너지 전환, 농업 농촌 시스템 전환, ICT 정책 패러다임의 전환에 적용된 리빙랩 사례를 살펴보고 우리나라에서의 시사점을 도출하였다. 유럽의 SusLab 프로젝트, C@R 프로그램, 대만의 리빙랩 사례 모두 사전기획 단계부터 지역 사용자의 배경과 경험을 적극적으로 수집하고, 사용자 주도의 혁신활동을 개발프로세스 전반에서 유지함으로써 적실성있는 문제해결은 물론 다양한 전환 실험을 성공적으로 추진하였다. 이러한 결과는 중앙정부와 지자체의 R&D사업에서 각각 리빙랩의 도입을 검토하는 우리나라에 다양한 시사점을 제공한다. 리빙랩은 국가 또는 지역 전반의 사회 기술시스템의 전환을 위한 전략적 니치 실험, 정책 간 연계통합의 수단, 새로운 지역혁신 모델로 활용될 수 있다. 또한 최근 혁신정책 패러다임에서 강조하고 있는 사용자 및 수요 측면을 반영한 정책통합을 실현할 수 있는 중요한 플랫폼이 될 수 있다.

유동층 반응기를 이용한 프로판의 촉매 분해는 $CO_2$를 방출하지 않고 수소를 생성하는 새로운 방식이다. 카본블랙을 이용한 프로판 분해는 메탄보다 상대적으로 분해가 잘되며, 같은 온도에서 전환률이 높기 때문에 수소 생성량이 더 많다. 촉매로 사용된 카본블랙은 반응 중 생성되는 탄소의 침적에도 불구하고 8시간 이상 촉매의 활성이 유지되어 전환율이 일정하게 유지되었다. 프로판 촉매 분해 실험은 상압에서 600 ${\sim}$ $800^{\circ}C$ 온도 변화 실험을 수행하였고, 가스 유속 변화는 2.0 ${\sim}$ $4.0U_mf$에서 실험 조건 변화에 따른 실험을 하였다. 온도, 유속 변화에 따른 생성 가스의 몰분율과 프로판 전환율을 분석하였다. 프로판 분해에 의해 생성된 기체는 수소뿐만 아니라 메탄, 에틸렌, 에탄, 프로필렌과 분해되지 않은 프로판이 배출되었다. 수소를 제외한 여타 가스들은 고온에서 실험을 할수록 몰비가 줄어들었다. 고온에서 프로판의 전환율과 수소 수득률이 증가하였다. 프로판 분해 실험 전후의 카본블랙 표면의 변화는 FE-TEM으로 관측하였다.

Multitasking has become part of our life. Self-interruption and switching to another task become easier and more frequent. According to previous studies, however, most of the task-switching incurs a cognitive cost. This study investigated the benefit from task switching. In Study 1, participants performed two tasks were similar, and negative correlation between the number of task switching and performance were confirmed, this result is similar to previous studies. Study 2 has shown that, made a comparison of two conditions, between possible and impossible conditions in terms of task switching. Depending on switching preference, the result of task performance has differentiated and the emotion that participants had before the task has changed. Depending on participants' switching preference, there were different amount of switching cost. Moreover, for participants who preferred task switching highly than others, task switching occurred more benefit than cost.

The purposes of this study were to identify the effects of distraction strategies compared to usual pain management, and to compare the effects of passive and active distraction on pain responses of preschool children during immunization. A quasi experimental with non-equivalent control group posttest design was used. Participants for each group were 30 preschool children who visited a pediatric clinic to have influenza immunization. Children in experimental groups selected one of two distraction types. Pain responses were measured by children, parents, and researcher. Pain responses by children, parents, and researcher during immunization were significantly different between groups. Children in passive or active distraction group were more distracted than children in control group. Moreover, self-reported pain response by children($2.70{\pm}0.88$) and researcher($12.97{\pm}2.39$) in active group were higher than pain scores by children($2.27{\pm}0.64$) and researcher($10.63{\pm}1.65$) in passive group. Results of this study identified that distraction intervention is an effective method for decreasing pain responses in preschool children during immunization. Passive distraction is more effective than active distraction. Use of distraction strategies during immunization should be facilitated. Further research comparing distraction strategies by types and forms is needed.

Current Korean innovation system is facing a new turning point while the growth-oriented and S&T provide-oriented development strategy. Accordingly, there are needs for not only system transition in various area, such as sustainable energy, agriculture, and rural area but also STI policy paradigm shift to create a new innovative pathway. Living lab is being discussed in European country as a new innovative model based on user participation and as a niche experiments for sustainable system transition. This study attempts to analyze the living lab cases which are for the purpose of energy transition, agriculture rural areas system transition, and STI policy paradigm shift. Based on this analysis, the implications were derived in Korea. European Suslab project, C@R project, and Taiwan living lab, promoted diverse transitional experiments successfully by collecting users' background and experiences from pre-planning stage and by maintaining the user-driven innovative actions within the whole development process. This result provides various suggestions to current Korean situation that central government and local governments are considering the introduction of living lab. Living lab can also be utilized as a strategic niche experiments for socio-technical system transition in region or country, as a mean of policy integration, and as a new regional innovation model. In addition, it can be an important platform to realize the policy integration reflecting the user and demand-side which are highlighted in recent innovative policy paradigm.
