This paper makes a brief analysis of the differences in Zhou brother's tea culture. From which we can see that the two views of tea culture and their personality trends, world view, outlook on life, aesthetics have a close connection. Lu Xun upheld respecting the people’s world view, while Zhou Zuo-ren could not view the world from a macro perspective because he paid too much attention to egoism and liberal worldview. Lu Xun payed more attention to the daily tea, Zhou Zuo-ren payed so much attention to the art of tea. Just as literature cannot exist independently from history and society, tea culture cannot be separated from human society. In the twenties and thirties of the twentieth century, China was facing a crisis of life and death. The essence of elegant beauty, noble beauty is actually irresponsible paralysis, but the essence of simple beauty is the "last struggle" and "fighting." Separating from the immediate reality of the society and blindly pursue elegant beauty is tantamount to nonsense. Before death, Lu Xun has also been putting Zhou Zuo-ren's work on the pillow in order to read at any time. Zhou Zuo-ren also wrote some books of Lu Xun in his later years. Today, such as the parallel line of alienated two brothers, the inner world of their later years has become the topic of life and literature.

This study aims to perform the economic analysis to the use of solar power facilities in rural villages considering the climate change scenario. IPCC climate change scenarios in the recently adopted the RCP scenarios (RCP8.5, RCP6.5, RCP4.5, RCP2.6) was used. By RCP scenarios, solar radiation, depending on the scenario in 2100, respectively, 3.6%, 2.5%, 1.9%, 1.1% was assumed to increase. From the economic analysis(payback period is 25 year) on 8 points of each province, in all cases of normal data and four RCP scenarios, at all points analyzed were NPV indicate a negative, BC ratio less than 1.0, respectively. In the case of Mokpo, Chunnam RCP8.5, BC ratio were found to be up to a 0.92, followed by 0.89 in the case of RCP8.5 in Jinju, Kyungnam shows, while the minimum was in Jeju. BC ratio is 1.0 or bigger, in order for the normal solar radiation data in Mokpo, Chonnam was the minimum that it takes 37 years. Similarly, in the case of RCP scenarios, 30 years in Mokpo, Chonnam RCP8.5 and 31 years in the cases of Jinju, Kyungnam and Jeonju, Cheonbuk RCP8.5 were analyzed. It was analyzed that RCP8.5 has the highest value. BC analysis models for each of the factors, the results of the sensitivity analysis, the initial installation costs, electricity sales price, discount rate in the order of economy showed higher sensitivity, and the rest factors showed lower changes. Although there are some differences of solar radiation by region, but in Korea most facilities in rural areas, the use of solar power was considered to be economical enough, considering change of several factors with high sensitivity, such as increasing of government subsidies for the solar power installation of the facility, rising oil prices due to a rise in electricity sales price, and a change in discount rate. In particular, when considering climate change scenarios, the use of solar energy for rural areas of the judgment that there was more economical.

본 연구는 지역항만 발전을 위한 항만운영기관의 역할과 관련하여 항만공사(PA)가 운영 중인 부산 인천 울산항을 중심으로 중요 역할을 도출하고 각 부분별 세 항만의 운영 효율 우선순위를 정하는 연구이다. 연구 방법론으로 요인분석 및 Fuzzy분석을 사용하였고, 선행연구를 통해 항만공사 및 지방해양항만청의 중요역할을 총 13가지의 하위평가요인으로 선정하였다. 또한, 요인분석을 통해 항만안전 및 정보관리를 포함한 총 4가지 상위평가요인으로 그룹핑 하였고, Fuzzy분석을 통해 각 항목의 중요도를 선정한 결과 항만마케팅이 가장 중요한 요인으로 선정되었다. 각 상위평가요인 및 측정변수에 따른 부산 인천 울산항만 운영기관 순위를 정한 결과, 부산항만운영기관이 1위를 차지하였고, 인천항만운영기관은 2위, 울산항만운영기관이 3위를 차지하였다. 결론적으로, 각 항목별 항만의 순위 점검을 통해 부족한 부분을 우선적으로 보완해 나간다면 향후 각 지역별 항만의 발전계획에 중요한 지표로 사용될 수 있을 것이라 판단된다.
