This study aims to clarify the effect of forest management practices(thinning and pruning) on water quality to get the fundamental information on the facility of cleansing water quality after forest operation. Rainfall, throughfall and stemflow were sampled at the study sites which consist of Abies holophylla and Pinus koraiensis in Kwangnung Experimental Forest for 6 months from May 4, to November 1, 1999. Average tree height in the management sites increased by 0.5m more than that in the non-management sites in Abies holophylla and Pinus koraiensis, respectively. Increment of average D.B.H. at the management sites grew 3.5㎝ and 2.6㎝ more in Abies holophylla and Pinus koraiensis compared with that at non-management sites. Average pH of the total amount for the event in throughfall and stemflow was higher than that of throughfall and stemflow of the beginning of the event at the management and non-management sites. Average electrical conductivity of throughfall and stemflow at the beginning of the event was higher than that of the total amount for the event at management and non-management sites. Water qualities of throughfall and stemflow were buffered more by the management practice in both. The forest management may affect purification of water quality of throughfall and stemflow in Abies holophylla and Pinus koraiensis.

This study was performed on the bases of clinical consideration about patient who has malaria. The symptoms of malaria are periodic alternating of chills and fever on everyone, two or three days. The patients feel a chill at the first time of malaria, and have a fever, headache and sweating at the next time. The long cycle of malarial fever such as every 2 or 3 days means that it takes a turn for the worse. In this study, oriental medicine was taken based on the oriental medicine principle such as Dalwonum(達原飮), Sosihotang(小柴胡湯) and Bojungikgitang(補中益氣湯), and the patients take a turn for the better. In the process of treatment if there is no fever in the expected date of the malarial fever, it is sure to have fever in the next expected date. It is favorable that patients lose the chills first and the fever lately in the process of treatment, and we can explain that supporting healthy energy to eliminate evil(扶正祛邪). The long cycle of malarial fever such as every 4, 6 or 9 days means that it is just before the recovery.
비협조적 게임이론을 활용한 신재생발전사업 갈등 사례분석
박재현,김경국,김경석 대한토목학회 2024 대한토목학회논문집 Vol.44 No.2
정부는 신재생에너지 정책을 통해 신재생에너지 시설확대를 독려하고 있다. 그러나 신재생에너지 발전시설 설치로 인해 발생하는 경관훼손, 전 자파발생, 부동산 가치하락, 환경오염 등의 사유로 인해 지역주민들의 민원이 발생한다. 이는 발전사업자와 주민들 사이에서 갈등을 만들며, 사 업 진행을 어렵게 만든다. 본 연구는 비협조적 게임이론을 적용하여, 주민참여를 통해 발전사업자와 주민들의 갈등을 해결한 신재생에너지 발전 사업 8가지 사례를 분석하고자 한다. 인근 이해당사자인 지역주민들의 투자를 받아, 주민들은 최대 25 %에서 최소 4.1 %의 수익률을 얻었다. 주 민들은 발전사업 추진에 동의하고, 발전사업자는 수익의 일부를 주민들과 공유하는 것이 게임이론 분석을 통해 모두에게 우월전략임을 확인했 다. 우월 전략이 만나는 지점은 내쉬균형을 형성하며, 동시에 파레토최적점이 되어 발전사업자와 주민 모두에게 이익이 된다는 분석결과를 도출 하였다. The government is encouraging the expansion of renewable energy facilities through national renewable energy policy. However, the installation of renewable energy generation facilities has led to local resident complaints due to landscape degradation, electromagnetic wave emission, real estate devaluation, and environmental pollution. This creates conflicts between power project developers and residents, making the progress of projects more difficult. This study applies non-cooperative game theory to analyze eight cases of renewable energy projects where conflicts between developers and residents were resolved through resident’s investment participation. By accepting investments from local stakeholders, residents achieved returns ranging from a maximum of 25 % to a minimum of 4.1 %. It was found through game theory analysis that a dominant strategy involves residents agreeing to the development of the project and the developers sharing a portion of the profits with the residents. The analysis results show that the point where dominant strategy meet forms a Nash equilibrium, and at the same time becomes the Pareto optimal point, benefiting both power generation operators and residents.

Green Tourism is broadly defined as local revitalized strategies which utilize local resources and come in contact with city inhabitants through taking the lead of local dwellers. The background of activation of Green Tourism is income-increasing , transformation of leasure trend and demand of sustainable development and endogenous development.Entering 21st century, a new form of tourism has been required, which can be friendly with nature with a view to develop tourism and promote a community. Among new forms of tourism in 21st century, Green Tourism has been focused most.The tourism tend is changing from city tour, spa tour and group tour to tour village tour and family tour, which experiences the stay at farm, mountain and fishing village. Recently, one of the tourism development in Korea and Japan to activate community promotion and community economy is the push of Green Tourism by community union.The push of Green Tourism, which is made by community residents and community union, can get the result, such as ①green tourism is connected to education experiment active program of students, ②a sight-seer should have made a long stay in rural region, ③pattern of green tourism is connected to famous circumference touristic place and sports institutions, ④various lodging institutions is necessary for green tourism. And successful green tourism is considerable to education and training of a guide, touristic service providers, instructors, consultants etc.Based on the result of the study, four issues were suggested : the consideration of sustainability, lcoal resident participation in the project, accessibility, and marketing & promotion.
