This study was performed to evaluate the quality characteristics of avocado breads adds different ratios of water-soluble chitosan. The dough raising power, specific volume, baking loss rate, volume and yield of avocado bread decreased with the addition of chitosan, however the weight increased. It is thought due to influence of viscous and water-holding capacity of watersoluble chitosan. In color values, with increase of chitosan content, L (lightness) value decreased in crumb, but a (redness) and b (yellowness) values increased. In the results of sensory evaluation, the avocado bread with the 0.5% or 1% chitosan showed the highest result in taste and flavor. Therefore, avocado bread will be used as a functional bread with improved taste by adding water-soluble chitosan.

본 연구는 특별교부세 배분에 영향을 미치는 요인에 관한 탐구이다. 특히 특별교부세 배분 연 구에서 충분한 관심을 받지 못했던 자치단체장 특성에 연구 초점을 맞추었다. 자치단체장의 정 치인 출신 여부, 당선횟수, 학력, 소속정당, 고위공무원단 상위 5개 대학교 출신 여부, 안전행정 부 관료 출신 여부를 독립변수로 하고 자치단체의 정치·사회·경제적 요인을 통제변수로 하여 설명모형을 구성하였으며 2005, 2007, 2009, 2011년 특별교부세 배분 자료를 이용하여 모형을 검증하였다. 분석을 위하여 패널자료 분석에 적합한 패널 FGLS(feasible generalized least squares)모형, 고정효과모형(fixed effect model), 확률효과모형(random effect model)을 이용하 였다. 분석결과 자치단체장의 당선횟수, 학력, 안전행정부 관료 출신 여부, 정치인 출신 여부, 집권여당 소속 여부가 특별교부세 배분에 영향을 미치고 있으며 통제변수로 사용한 자치단체 의 정치·사회·경제적 특성도 특별교부세 배분에 영향을 미치는 것으로 나타났다. 특히 자치단 체 국회의원의 역할이 중요한 요인으로 작용하고 있었다. 또한 자치단체의 인구가 많을수록 또 는 재정자립도가 낮을수록 더 많은 특별교부세를 배분받고 있음을 확인하였다. 결론적으로 특 별교부세 배분기제(allocation mechanism)에 있어 자치단체장이나 국회의원의 정치적 영향력, 그리고 자치단체의 실제적 재정수요가 중요한 요인임을 경험적으로 확인할 수 있었다. This study tries to find out the factors which determine the allocation of Special Revenue Sharing(SRS). Little attention has been paid to the mayors’ characteristics as determinants of the allocation of SRS. To fill this research gap three models―a FGLS model, a fixed effect model, and a random effect model―are developed in which mayors’ characteristics are used as major independent variables. Local governments’ political, social, and economic factors are also included in the models as control variables. The panel data of 2005, 2007, 2009, and 2011 SRS allocation is employed for the empirical analyses. The findings are as follows: (1) among the mayors’ characteristics education, political career, ruling party affiliation, the number of times elected as mayor, and whether or not the mayor is the former official of Ministry of Security and Public Administration have effects on the SRS allocation (2) the political influences of the district congressmen are critical to the allocation of SRS (3) among the socio-economic variables of the local governments the population size and the financial independence influence on the allocation of SRS. As the number of population increases or the degree of financial independence decreases the amount of SRS local governments receive increases (4) the political influences and the financial needs of the local governments are major factors which work dynamically in the SRS allocation process.

The purpose of this study was to investigate the antioxidant effect of water-soluble chitosan (WSCs), petal extracts of Abeliophyllum distichum Nakai (ADNPE), and WSCs/ADNPE. The yields of ADNPE with organic solvents (D.W, MeOH, and EtOH) were 37.07%, 33.59%, and 14.58%, respectively. The total polyphenol content of ADNPE appeared 10.53, 11.75 and 10.81 mg GAE/g. The total flavonoid content of ADNPE were 0.8, 2.23 and 1.67 mg QE/g. The total tannin content of ADNPE were 4.24, 6.93, and 5.9 mg TAE/g. The total proanthocyanidin content of ADNPE were 1.47, 1.87, and 1.59 mg CE/g. In the ADNPE with MeOH extracted at 1000 μg/ml, the DPPH radical scavenging activity, ABTS radical scavenging activity, and SOD-like activity were excellent. but, the antioxidant activity of SOD-like activity showed less than that of DPPH and ABTS radical scavenging activity. The antioxidant activities of DPPH and ABTS radical scavenging activity and SOD-like activity were in order of MeOH, EtOH, and D.W extracts, respectively. When WSCs added ADNPE, the DPPH and ABTS radical scavenging activity and SODlike activity of ADNPE/WSCs showed high antioxidant activities. This study showed that ADNPE and ADNPE/WSCs are good antioxidants.

본 연구는 광역자치단체에서 기초자치단체로 배분되는 시·군 조정교부금을 중심으로 재원배분 구조를 고찰하였다. 8개 도(道)의 152개 시・군을 중심으로 2011년과 2015년에 배분된 조정교부금 중 특별조정교부금 자료를 수집하여 패널자료를 구성하고, 고정효과모형(fixed effect model)을 이용하여 패널자료를 분석하였다. 각 시·군에 배분된 특별조정교부금을 종속변수로 하고 정치 요인과 행정수요 요인을 독립변수로 하여 분석모형을 구성하였다. 정치 요인의 하위변수로 기초자치단체장 당선횟수, 기초자치단체 지역구 시·도의원의 주요 보직 역임 여부, 광역자치단체장-기초자치단체장-시·도의원 정당일치 여부, 기초자치단체장 당선자와 2위 간 득표차, 기초자치단체의 광역자치단체장 지지율을 사용하였고, 행정수요 요인의 하위변수로 인구수, 재정자립도, 지역 면적을 사용하였다. 분석결과 기초자치단체의 정치 요인과 행정수요 요인 둘 다 특별조정교부금 배분에 영향을 미치는 것으로 나타났다. 정치 요인 중 기초자치단체장 당선횟수와 광역자치단체장 지지율이 특별조정교부금 배분에 정(+)의 영향을 미치는 것으로 나타났으며, 행정수요 요인 중 재정자립도가 부(-)의 영향을 미치는 것으로 나타났다. 결론적으로 특별조정교부금은 ‘정치(politics)’ 요인 또는 ‘수요(needs)’ 요인 중 어느 한 쪽의 요인만이 영향을 미치는 이분법적 재원배분 구조가 아니며 두 요인이 상호 복합적으로 작용하는 구조를 가지고 있음을 경험적으로 확인하였다. This study explores the mechanism of intergovernmental transfer from provincial governments to city and county governments. The Provincial Revenue Sharing (PRS), known as adjustment grants, is comprised of general and special grants. We focused on the special grants which were allocated among city and county governments in 2011 and 2015. The panel data employed for the empirical analysis consists of 152 city and county governments within 8 provincial governments. To understand the determinants of the allocation of the special grants a fixed effect model is developed. The independent variables in the model are the political factors and financial needs of the city and county governments. The findings are as follows: (1) the political influences of the mayor and governor are critical in the allocation of the special grants. (2) the degree of the city and county governments’ financial independence has an effect on the special grant allocation: as financial independence decreases the amount of the special grants allocated increases. (3) the politics and the financial needs are major factors that work together dynamically in the special grant allocation.

추출용매에 따른 산수유 꽃의 항산화활성을 알아보고자 총 polyphenol, flavonoid 및 tannin의 함량을 조사하고, 꽃 추출 물, 꽃 추출물과+Cs 혼합용액의 DPPH radical 소거활성, ABTS radical 소거활성과 FRAP을 분석하였다. 추출물의 수율은 D.W.가 38.9%로 가장 높았으며, 총 polyphenol, flavonoid, tannin 모두 EtOAc가 다른 추출 용매에 비하여 높은 함량을 나타내었다. D.W., EtOH, MeOH, BuOH, EtOAc 추출물의 1 mg/mL 농도에서 DPPH radical 소거활성은 87.02~ 90.57%의 소거활성을 나타났으며, ABTS radical 소거활성은 95.29~96.79%의 높은 활성을 나타냈다. FRAP 활성은 1 mg/ mL 농도에서 흡광도가 0.92~1.72로 EtOAc가 가장 높은 흡광도를 나타내었다. DPPH, ABTS radical scavenging activity 및 FRAP assay 실험에서 추출물의 농도가 증가함에 따라 항산화력도 증가하였다. 추출물과 Cs 혼합용액의 DPPH 소거 활성은 추출물과 Cs 혼합비율이 9:1일 때 EtOH과 Cs 혼합 용액이 가장 높은 소거활성을 나타내었으며, ABTS는 혼합비 율이 6:4일 때 EtOAc과 Cs 혼합용액이 가장 높은 소거활성을 나타내었으나 FRAP는 EtOAc 추출물에서 가장 높은 항 산화력을 보였다. 이상의 결과로 보아 산수유 꽃 추출물의 우수한 항산화력을 나타내었고 키토산과 혼용할 경우 일정농도 에서 상승작용을 하는 것으로 보아 기능성식품을 위한 천연 항산화 물질로써 활용이 가능할 것으로 사료된다. The purpose of this study was to investigate the antioxidant activities of the D.W., EtOH, MeOH, BuOH, and EtOAc extracts of Cornus officinalis flowers (COF), and COF extracts+Chitosan (Cs). As a result, the yield of extract showed the highest value in an D.W. extract. The total polyphenol, flavonoid, and tannin showed 98.95 mg GAE/g, 17.96 mg QE/g, and 81.26 mg TAE/g at the EtOAc extract. The COF extracts at a concentration of 1 mg/mL, the ABTS radical scavenging activity and FRAP assay indicated the hightest activity with EtOAc extract. And DPPH was high value in an EtOH extract (90.57%). We knew that the EtOAc extract is good antioxidant potential. It can be seen that these effects are due to the polyphenol and flavonoid. The addition of Cs in the extracts of COF improved the DPPH and ABTS radical scavenging activity. As the result, extracts of COF and Cs are going to be used as a nature antioxidant and antioxidants substance for functional foods.

순천시 기후학교 환경교육에 대한 초등학생들의 인식 및 교육효과

김대희(Daehee Kim),안삼영(Samyoung Ahn),강아름(A-reum Kang),유보람(Boram Yoo),이복남(Boknam Lee) 한국환경교육학회 2009 環境 敎育 Vol.22 No.4

While global warming and climate change have been issues with global implications for ecology and nature as well as for the economy, politics and social sector, Korean's climate change awareness has been reported to be low. This phenomenon can be attributed to the fact that there is neither a systematic and continuous educational program for climate change nor a system to implement and support it. Although environmental education traditionally has not been a center of focus in most schools, the move towards green growth in national policies are slowly influencing school education as well. Throughout the year 2009, Green Suncheon 21 has offered a program called 'Suncheon Climate School' designed for elementary schools and regional centers for underprivileged children. Program instructors were sent to schools and centers that requested such climate change education. The aim of this study is to evaluate the success of the program and to provide feedback on its impacts. According to the study, students' interests in climate change have increased after the climate change education, and students found the lectures to be informative and interesting. Students said that they became more aware of the serious consequences of global warming and climate change and found that such education is beneficial and should be available to a wider population. This study suggests that first, school teachers should be aware of climate change and support such educational programs to be a part of the regular curriculum. Second, the content and the level of the program should be designed in consideration of the corresponding school curriculum to make the subject relevant and accessible to students.
