The effect of forest-thinning works on tree growth and forest environment
강정석,신창섭,Masato Shibuya 한국산림과학회 2014 Forest Science And Technology Vol.10 No.1
This research was conducted to provide effective forest management through forest tree production and forest land changeswhich took place after the forest-tending works in the plantation of Pinus koraiensis. It has been shown that the currentannual diameter growth of trees in regions which implemented forest-tending projects in 2005 had increased by 142.9%compared to those which did not implement the forest-tending projects. In 2006, the current annual diameter growth oftrees in implemented regions increased by 132.6% compared to those which did not implement forest-tending. Additionally,in the Pinus koraiensis plantation of II–III age classes where forest-tending projects works were implemented, thegrowth in diameter started to show a clear increase in the year following the implementation, and the maximum effectswere displayed within 3–5 years. Thereafter, the growth gradually started to slow down. Therefore, implementing foresttendingworks repetitively with a minimum period of 5 years would be considered appropriate. Soil moisture during therainy season did not show significant differences as the soil moisture content remained at 40.4–43.0%. However, duringthe dry season, regions which did not implement forest-tending showed an average of 20.4%, and regions which implementedforest-tending showed an average of 26.6%, and the differences were greater when compared to the rainy season. Due to the control in the density of the number of forest trees due to forest-tending and forest thinning works, the numberof understory woody plant species increased from 17 to 30 and the number of herbaceous plant species increased from20 to 44. Furthermore, as the density of standing trees was reduced to about 50% in places where forest-tending workswere implemented, crown length ratios increased greatly from 46.1% to 62.1% and became a great help to the growth offorest trees.

The goal of this research is to develop effective strategies for blood donation communications that help increase blood donation rate in Korea, based on social marketing perspective. To obtain the goal, study 1 and study 2 were conducted as follows. In Study 1, 6 communication message types that were frequently used for blood donation communications in Korea were selected from content analysis. In Study 2, an online survey was conducted among 1,200 males and females between the ages of 18 and 69-years-old in Korea. Based on blood donation activities, target audiences for blood donation communications were divided into non-donor, uncommitted ex-donor, committed ex-donor, uncommitted repeat donor and committed repeat donor segments. Next, specific blood donation communication messages that enhanced blood donation intention for each segment were found and specific media vehicles that were frequently used by each segment were identified. Finally, considering characteristics of each of five segments together, the research suggested the effective blood donation communication message and media strategies for each segment. 본 연구의 목적은 사회적 마케팅 관점을 기반으로 국내 헌혈률 제고에 기여하는 효과적인 헌혈 커뮤니케이션 전략을 개발하는 것이다. 이를 위해서 다음과 같이 연구 1과 연구 2를 진행했다. 연구 1에서 내용분석을 통해 국내 헌혈 커뮤니케이션 활동에서 주로 사용한 6개의 헌혈 커뮤니케이션 메시지 유형을 선정했다. 연구 2에서 1,200명의 18-69세 남녀를 대상으로 온라인 설문조사를 실시하였다. 온라인 설문조사 자료에서 헌혈 경험을 기준으로 헌혈 커뮤니케이션의 목표 청중을 비헌혈자, 저빈도 헌혈 중단자, 고빈도 헌혈 중단자, 저빈도 헌혈 지속자 및 고빈도 헌혈 지속자 집단으로 세분화하였다. 이후 각 세분집단 별 헌혈 의향을 높이는 특정 헌혈 커뮤니케이션 메시지 유형을 확인하였고 각 세분집단 별 이용 빈도가 높은 세부 매체 종류를 파악했다. 최종적으로 본 연구는 각 세분집단의 특성을 함께 고려해서 각 세분집단 별 효과적인 헌혈 커뮤니케이션 메시지와 매체 전략을 제안하였다.
