본 연구의 목적은 도시가 지속가능한 방향으로 전환되는 과정을 촉진시키기 위해 요구되는 조건과 요소를 분석하는 데에 있다. 이를 위해 지속가능성 전환 도시정책의 선진사례인 ‘환경수도 수원’을 중심으로 문헌고찰과 심층인터뷰를 병행한 사례연구를 수행하였다. 그 결과, 주요하게 작동한 핵심 조건과 요소로는 첫째, 도시전환 과정을 설계하고 이끄는 선두주자와 이들을 지원하는 전담조직, 협력적 사회 네트워크 구성과 매개체로서의 중간지원조직, 마을단위의 실행공동체로 분석되었다. 이에 도시의 지속가능성 전환을 위해서는 국가-도시 단위를 아우르는 다층적 상호작용의 도모, 참여주체 간 인식증진 및 역량강화를 위한 상호학습 기제 마련, 그리고 각 도시에 내재된 강점/약점 분석을 통한 전환 환경의 조성이 정책적 시사점으로 제시되었다. The aim of this study is to identify enabling conditions and elements that can collectively accelerate sustainability transition processes in urban areas. To do this, a case study of a pioneering urban transition intervention-the Eco-capital Suwon-was conducted, using two methods of document analysis and in-depth, semi-structured interviews. As a result, dominant enabling conditions and elements were identified: 1) empowered frontrunners and transition teams; 2) collaborative actor networks and intermediaries; and 3) communities of practice (CoPs) at the neighbourhood level. Based on the findings, this research suggests the promotion of multi-scalar interaction across national-urban territories, the development of social learning schemes, and the analysis of embedded strengths/weaknesses of the transition arena.

In the current study, we investigated the inhibitory activity of water soluble β-glucan from oat (Avena sativa) against various digestive enzymes such as α-glucosidase, sucrase, maltase and glucoamylase. Inhibition of these enzymes involved in the absorption of disaccharide can significantly decrease the post-prandial increase of blood glucose level after a mixed carbohydrate diet. The β-glucan had the highest documented rate of small intestinal sucrase inhibitory activity (2.83 mg/mL, IC₅₀) relevant for potentially managing post-prandial hyperglycemia. Furthermore, we evaluated the effects of β-glucan on the level of post-prandial blood glucose in animal model. The post-prandial blood glucose levels were tested two hours after sucrose/starch administration, with and without β- glucan (100, and 500 mg/kg-body weight). The maximum blood glucose levels (Cmax) of β-glucan administration group were decreased by about 23% (from 219.06±27.82 to 190.44±13.18, p<0.05) and 10% (from 182.44±13.77 to 165.64±10.59, p<0.01) in starch and sucrose loading test, respectively, when compared to control in pharmacodynamics study. The β -Glucan administration significantly lowered the mean, maximum, and minimum level of post-prandial blood glucose at 30 min after meal. In view of the foregoing, it is felt that our findings suggest that β-glucan from oat serves to reduce post-prandial blood glucose rise secondary to slower absorption of glucose in the small intestine, via carbohydrate hydrolyzing enzymes inhibition.

본 연구는 영재청소년의 긍정적 발달과 성장을 위해 영재청소년의 성장 마인드셋과 회복탄력성의 관계에서 그릿의 매개효과를 살펴보는데 목적이 있다. D광역시에 소재한 영재원에 재원 중인 초6학년, 중학생 95명을 대상으로 자기보고식 설문을 실시하였고, 구조방정식 모형으로 분석하였다. 연구 결과는 다음과 같다. 첫째, 성장 마인드셋은 회복탄력성에 직접 영향을 미치지 않는 것으로 나타났다. 둘째, 성장 마인드셋에서 그릿은 정적으로 영향을 미치는 것으로 나타났으며, 그릿은 회복탄력성에 정적으로 영향을 미치는 것으로 나타났다. 셋째, 성장 마인드셋과 회복탄력성의 관계에서 그릿이 완전매개 효과로 나타났다. 결과적으로 영재 청소년이 성장 마인드셋 성향과 회복탄력성을 가지고 있다면, 목표에 대해 꾸준히 노력하는 성향 또한 가지고 있다는 점을 시사한다. 끝으로 그릿과 회복탄력성의 두 변인에 대한 이해를 통하여 영재청소년의 심리적, 교육적 개입전략을 세울 수 있을 것으로 보인다. The study is concerned with addressing the mediating effect of the grit on the relationship between the growth mindset and resilience of gifted youths. Accordingly, the self-report type questionnaire survey was done for the 95 gifted youths of the 6th graders and middle school students in the gifted center located in D metropolitan city and was analyzed with the structural equation model. Research results are as follows. First, the growth mindset of gifted youths doesn’t directly affect resilience. Second, grit affects the growth mindset, and grit also statically affects resilience. Third, grit is a complete provocation between growth mindset and resilience. As a result, it is implied that if a gifted youth has both the growth midset and resilience, the youth also has a grit which makes it possible for him to be steady. Lastly, it is expected that psychological and educational intervention strategy can be established by understanding the two variables of grit and resilience.

Objectives:The aim of this study was to determine whether children with Tourette disorder (TD) have functional impairment and executive dysfunction in comparison to children with attention-deficit hyperactivity disorder (ADHD) and non-affected controls. Methods:From January 2006 to December 2013, 45 children and adolescents with TD and 50 children and adolescents with ADHD diagnosed at the Soonchunhyang University Bucheon Hospital and 50 non-affected controls were enrolled in this study. Functional impairment of the subjects was assessed using the Child and Adolescents Functioning Impairment Scale (CAFIS), parent and teacher versions. In addition, neuropsychological tests including Stroop color-word Test, Finger windows Test (FWT), and Digit span were administered. Outcomes were compared across the TD, ADHD, and non-affected controls. Results:No difference in CAFIS-parent and CAFIS-teacher results was observed between children with TD and non-affected controls, whereas, children with ADHD showed more impairments relative to non-affected controls in the CAFIS-parent. According to the Stroop color-word Test, FWT, and Digit span, executive function in children with TD did not differ from non-affected controls. Children with ADHD had poorer performance in measures of the Stroop color-word Test compared to children with TD. Conclusion:Children and adolescents with TD but not ADHD were not significantly different from non-affected controls on most measures of functional impairment and executive function. These findings suggest that an education program and intervention for children with TD would be important to reducing the stigma of TD.

The purpose of this study is to investigate the effects of blended learning pre-task activities and learners’ self-regulation on Korean college students’ speaking skills and their perceptions of blended-learning pre-task activities. The participants were 42 EFL students from a university in Gyeonggi-do, Korea and they were divided into three groups: a blended-learning group (n=13), a blended-learning and self-reflection group (n=15), and a control group (n=14). The experiment was administered during the spring semester of the 2018 academic year. The major findings from the study are as follows: First, the blended-learning pre-task activity followed by self-reflection was the most effective in enhancing students’ English speaking skills, whereas the blended-learning and the face-to-face classroom activities showed beneficial and equal effects on the improvement of the speaking skills. Second, the self-regulated learning of the experimental group learners proved to be a key factor in the success of the blended learning. Third, the participants of the experimental groups responded positively to their experience of blended-learning pre-task activities. The findings indicate that blended learning pre-tasks and self-reflection activities need to be integrated into the teaching of English speaking to overcome the limitations of the EFL contexts.
