Green colored citrus is the immature fruit of the field citrus crop in Jeju, and its demand has been growing recently as it is known to contain a large amount of carotinoid, pectin, and vitamin C. It differs from the traditional varieties of blue tangerine, which are green in February and turn in yellow in March-April. This study analyzed the effects of the increased demand in green citrus on the field citrus industry. For our analysis, a partial equilibrium supply-demand model was established with a dynamic recursive structure using data from 1989-2017. Model calibration was also conducted to determine the best supply-demand model and then, the impacts of increasing demand for green immature citrus in Jeju for 2018-2030 was simulated. The simulation results show that there is no significant impact on the producing area prior to 2022, but there is a distinguishable increase of 18ha in 2023, 52ha in 2025, and 142ha in 2030. It was also predicted that revenue would increase by KRW 7.75 billion on average from 2021-2030.

유역의 도시화는 지체시간, 첨두유량 및 총 유출량 등 홍수 유출특성 뿐만 아니라 개발행위에 따른 토사유출특성 변화를 초래하는 등 다양한 문제를 유발하고 있다. 또한 인구증가, 산업발달, 교통량 증가로 인한 화석연료의 소비증가로 대기 중의 이산화탄소의 농도가 급증하여 기후변화에도 큰 영향을 미치고 있다. 이러한 지나친 도시화 진행을 억제하고 웰빙과 건강에 대한 관심 증대에 따라 저탄소 녹색사업의 일환으로 도시 녹지조성 계획이 진행되고 있다. 따라서 본 연구에서는 도시하천인 중랑천 ($288km^2$) 유역을 대상으로 도시화 진행에 따른 토지이용 변화가 강우-유출 특성에 미치는 영향을 분석하였다. 이를 위해, 중랑천 유역의 과거 (1975, 1980, 1985, 1990, 1995, 2000) 토지 이용도로부터 각 항목별 면적변화 추이를 분석한 결과, 17.8%의 도시지역 면적 증가가 나타났다. 미래토지이용 예측을 위하여 CLUE-s (Conversion of Land Use change and its Effects) 모델을 이용하였다. 과거 토지이용 변화 특성을 분석하여 토지피복의 변화와 전이 특성값을 결정하였고, 이를 바탕으로 토지면적 시나리오, 변화 제한지역, 회귀식 결과와 토지이용 변화 특성에 따른 CLUE-s 모델을 이용하여 미래 토지이용변화 (2040, 2080) 모의를 실시하였다. 이러한 토지이용 변화에 따른 유출특성변화 모의를 위해, 물리적 기반의 준분포형 강우-유출 모형인 SWAT (Soil and Water Assessment Tool) 모형을 이용하였다. 모형의 적용성 평가를 위해, 매개변수 민감도 분석에 따른 도시유역 최적의 유출관련 매개변수를 선정하고 중랑교 지점의 일별 유출량자료(2000~2009)를 이용하여 보정 및 검증을 실시하였다. SWAT 모형의 검보정 후, 예측된 미래 토지이용도를 적용하여 과거와 현재, 미래 토지이용변화에 따른 유출특성변화를 비교분석하였다.

Republic of Korea officially announced its mid term reduction target which reduce about 30% of BAU GHG emission by 2020 in the 15th meeting of UNFCCC(COP 15) held in Copenhagen, Denmark 2009. To achieve this goal, it is necessary to understand the serious of climate change and take part in GHG reduction not only industry but also the nation. However, such positive participation in green life which may cause inconvenient of the life of the people. It should be accomplished with providing reliable information. This study suggests the scientific potentialities of GHG emission by guideline on low carbon life and green life to form and change a lifestyle suitable for coping with climate change. And also, this study quantitate the GHG reduction which may reduce demand for air conditioning by cool biz and warm biz. In Korea, this campaign has become known as 'CoolMaebsi' by Ministry of Environmental of Korea. 'CoolMaebsi' is a compound word of 'Cool' which means feel refreshed, and 'Maebsi' is a Korean word which means attire. Though this campaign is effective and significant to reduce the GHG emission yet there were no study on quantitative analysis. Therefore this study calculated reduced energy consumption and potential GHG emission by measuring variation of skin temperature. As the result, wearing warm biz and cool biz have an effect of reducing not only the energy consumption but also GHG emission. To achieve the low carbon society, it is necessary to improve the energy saving system and introduce the policy which guide to change a life style.

This study investigated the consumption tendency and awareness of paprika in order to expand and promote the consumption of Capsicum annuum L. The research investigated the relationship of preference and loyalty based on emotional response of paprika according to the semantic differential scale. The survey was conducted from January to February 2022 using a random sampling method targeting 155 general people, and a total of 142 questionnaires were analyzed excluding 13 wrong answers. The nine items on the awareness of paprika showed to be consisted of three factors such as 'Food taste', 'Usability', and 'Economics' by factor analysis. Regarding to the awareness of paprika the positive answer that 'I think paprika is good for health' among the nine questions was the highest at 92.3%. In the preference aspect of shape, blocky type had the highest preference for the shape of paprika, followed by mini and conical types in order of preference (p < 0.001). As for color preference, yellow paprika was the most preferred, followed by orange, red, and green, showing statistical significance. The emotional response of paprika by paprika image showed a statistically significant difference in the four colors. The words such as 'bright', 'clean', and 'spirited' appeared as representative emotional vocabulary for paprika. Multiple regression analysis was performed to examine the effect of paprika on the three factors of awareness, preference, and loyalty due to the quality of life. As a result, the higher the paprika preference and quality of life, and the higher the taste and availability factors, the higher the paprika awareness and loyalty. As the variable that has the most influence on the loyalty of the survey respondents, preference was found to have the highest explanatory power at 43%. From these results, it was judged as a very important factor in the survey on the shape and color preference of paprika. Therefore, the recent increase in awareness that paprika is good for health is thought to act as a positive factor in revitalizing the domestic market and increasing consumption of paprika in the future. Also, among the three types of paprika, the yellow blunt type showed the highest preference. Therefore, in order to produce and promote this type of paprika, it is also important to increase the cultivation to suit the purchasing propensity of consumers.
