        Captive breeding and reintroduction are crucial strategies for conserving endangered species populations. However, fish raised in predator-free environments, show a lack of recognition of predationrelated stimuli such as chemical and visual signals. It is critical to recognize chemical signals from injured conspecifics, also known as alarm signals, and the order or shape of predators to indicate the spread of predation risk in the habitat. We conducted a laboratory experiment to determine and adjust the optimal exposure period to induce appropriate anti-predator behavior response to different types of stimuli (Chemical, Visual and Chemical+Visual) for the endangered species Microphysogobio rapidus. Our results demonstrate that predator avoidance behavior varies depending on the types of stimuli and the duration of predation risk exposure. First, the results showed captive-breed M. rapidus show lack of response against conspecific alarm signal (Chemical cue) before the predation risk exposure period and tend to increase response over predation risk exposure time. Second, response to predator (visual cue) tend to peak at 48 hours cumulative exposure, but show dramatic decrease after 72 hours cumulative exposure. Finally, response to the mixed cue (Chemical+visual) tend to peak prior to the predation risk exposure period and show reduced response during subsequent exposure periods. This experiment confirms the lack of responsiveness to conspecific alarm signals in captive-bred M. rapidus and the need for an optimal nature behavior enhancement program prior to release of endangered species. Furthermore, responsiveness to predator visual signal peak at 48 hours cumulative exposure, suggest an optimal predation risk exposure period of up to 48 hours.

        Recent changes in the global climate environment have resulted in a wide variety of climaterelated disasters, including floods, tidal waves, forest fires, droughts, etc. In addition, global warming raises the risk of food poisoning, which may increase the spread of infectious diseases and alter their structure. Under these circumstances, it is necessary to provide accurate and persuasive information to consumers so that they can be fully informed of climate change and alter their behavior accordingly. Therefore, the intention of this study was to develop posters and contents for image production related to climate change and food safety. The posters are focused on consumers with headings such as 『Climate Change Threatening Food Safety』,『Earth getting warmer, your dining table is at risk』, 『Warning signs ahead for the globe』, and more. Five poster drafts were selected initially, and a survey was carried out amongst 1,087 people regarding their preferences, with the most preferred design chosen. The images related to climate change and food safety defined climate change, how it relates to food safety, the risks it poses to the food industry, and lastly, how the public can respond in the future. Therefore, to further communicate the importance of food safety to consumers, the development, education, and promotion of these contents should be performed to provide safety information to consumers in the future.

        본 연구는 친환경 도시농업을 통해 환경에 대한 중요성을 인식하고 효율적인 도시농업의 정착을 활성화하기 위한 목적으로 실시하였다. 친환경 도시농업은 도시민들에게 부족한 자연생활이 가능하도록 하며, 친환경 먹거리에 대한 인식을 지각하고, 건강한 삶의 질 향상과 친 환경 인식 변화에 도움이 되고자 한다. 또한 친환경 도시농업을 체계적으로 관리, 육성하여 보다 많은 사람들에게 도시농업을 확산시키고, 긍정적인 환경보전 효과를 거두고자 한다. 도시농업 활동에서 도시민들이 친환경 농법의 교육을 통해 텃밭 조성 및 농작물재배방법이 이루어 졌고 농작물의 수확도 친환경적으로 이 루어진 것으로 나타났다. 도시 농업에 이용하는 씨앗 및 모종도 친환경적이라고 생각하는 것으로 나타났고. 환경에 대한 인식변화에도 도 움이 되는 것으로 나타났다. 환경의 중요성 지각을 통해 행동의 변화에도 영향을 미친다고 답하였다. 도시농업활동을 친환경적이라고 이 웃에 소개할 수 있고 지속적으로 도시농업 활동에 참여할 것이라고 답하였다.

        This study was conducted to analyze the policy impacts of the ‘2014 Rural Field Forum’. From 2013, Ministry of Agriculture, Food and Rural Affairs implemented Rural Field Forum to push forward rural development of inhabitants′ initiative. In this study, we have evaluated that Rural Field Forum has crucial impacts on residents′ competence, region capability and driving force of project by targeting the 374 residents of 350 villages in 9 states who participated in 2014 Rural Field Forum. We also sought for the solution to institutional improvement. Futhermore we analyzed each of leader group and normal residents for departmentalization of policy effects. Taken together, the analysis reveals that: 1)Rural field forum is demonstrated to have a positive effect on the establishment and execution of village development plan and all of its necessary components. 2)Regarding the effect on the village capabilities, the understanding and recognition of village organization was shown to be improved. 3)About regional capabilities, the interest in village project was advanced. 4)In terms of the project execution, Rural field forum turned out to affect the village council processes positively. 5)lastly, between the leader and the residents, the difference effectiveness between them revealed, with the same directivity and considerably bigger effect felt by the leader than by the residents overall.

        이 연구는 설문조사를 이용해 기후변화와 인간의 삶에 영향을 미치는 다양한 현상 중 키메라현상에 대한 성별, 인문 및 이공 학문별 전문가 및 일반인들의 응답을 기초로 학제 간 융합연구의 토대를 마련하고자 조사하였다. 모든 응답자들의 기후변화에 대한 인식은 높은 것으로 나타났으며 특히 기후변화의 피해로 자연훼손을 우선으로 꼽고 있다. 기후변화 및 그 피해인식, 키메라현상이 개인에게 영향을 미친다는 대답에 대한 성별, 전문영역별, 연령별의 그룹 간에 유의성이 있는 것으로 조사되었다. 또한 응답자 중 이공계열 전문가 집단이 기후변화와 키메라에 대한 인식이 높았으며 키메라 현상에 대한 부정적 견해가 상대적으로 낮은 것으로 나타났다.
