        자연휴양림의 종다양성 증진을 위한 식생관리 방안 연구 -경기도 축령산자연휴양림을 사례로-

        이태선 ( Tae Sun Lee ),이경재 ( Kyong Jae Lee ),최병언 ( Byung Un Choi ),박석철 ( Seok Cheol Park ) 한국환경생태학회 2010 한국환경생태학회지 Vol.24 No.4

        본 연구는 휴양림의 기능 향상을 위한 식생관리 방안을 제시하고자 경기도 남양주시 수동면 외방리 축령산자연휴양림을 대상으로 실시하였다. 휴양림 내 등산로 및 산책로 주변의 주요 분포종인 잣나무 인공식생지와 자연식생지인 낙엽활엽수림의 생물다양성 조사 및 분석 등을 실시하여 휴양림 기능향상을 위해 식생유형별 관리를 위한 관리방안을 도출하였다. 연구방법은 생물다양성 측면에서 식생관리, 현존식생 및 비오톱 현황, 식생유형 구분, 식생구조, 야생조류 서식구조 등의 기능검토를 실시하였다. 휴양림내 식생유형 구분은 현존식생과 비오톱현황을 기초로 잣나무 인공조림지와 자연상태의 낙엽활엽수림으로 크게 구분할 수 있으며, 등산로 및 산책로 주변 대표식생 조림여부, 식생관리 등에 따라 4개의 유형(관리되지 않은 인공 잣나무림, 관리된 인공 잣나무림, 단풍나무 비율이 높은 자연상태의 낙엽활엽수림, 관리된 낙엽활엽수림)으로 구분하였다. 식생구조 분석결과 종다양도는 낙엽활엽수림이 인공 잣나무림 보다 종다양도가 높게 나타났고 관리되지 않은 상태가 관리된 상태보다 종다양도지수가 높게 나타남을 알 수 있었다. 야생조류 서식구조 분석결과 관리된 잣나무림은 층위구조가 빈약한 단층으로 식재되어 다양한 야생조류의 이동통로로서 부적합한 구조이고, 관리되지 않은 자연상태의 낙엽활엽수림, 잣나무림 등이 양호한 야생조류 서식구조를 가지고 있음을 알 수 있었다. 생물다양성 기능 검토에 근거하여 관리유형을 크게 보전관리와 복원관리로 구분할 수 있었다. 보전관리 중 기존낙엽활 엽수림 유지유형은 자연상태의 낙엽활엽수림 지역, 관리된 낙엽활엽수림 지역 등이 속하며 생태적 관리유형은 관리되지 않은 인공 잣나무림 지역을 설정하였고, 복원관리지역인 생태적 복원유형은 관리된 인공 잣나무림 지역으로 설정하여 식생관리 유형별 관리방안을 제시하였다. This study was supposed to offer vegetation plans for functional improvement of the recreational forest by researching Mt. Chukryong which is located at Oebang-li Sudong-Myon Namyangju Kyong-gi Province inKorea. In this study, artificial vegetation and natural vegetation near trails in recreational forest were researched through biodiversity analysis. From this analysis process, a typical management improvement of the biodiversity functions were examined by reviewing functions biotope condition, vegetation structure and wild bird community condition. Typical vegetation system was divided into four detail parts: Managed artificial Pinus koraiensis forest, Not managed artificial Pinus koraiensis forest, Natural deciduous forest and Not managed deciduous forest. As a result of the vegetation structure, the numerical value of the deciduous forest species diversity was higher than that of artificial Pinus koraiensis, and the numerical value of the managed condition was higher than that of not managed condition. As a result of a habitat structure analysis of the wild bird community, managed Pinus koraiensis forests were inadequate structure for wild birds to habit in there because the forests had weak structure layers, but unmanaged deciduous forest and unmanaged Pinus koraiensis that had diverse layers was proper places for birds to in habit. Thus, based on the functional analysis of biodiversity, management patterns of the target area were concluded in two manners: conserving management and restoring management. Deciduous forest protection target areas included natural deciduous forest area and managed deciduous forest area, ecological restoration target area included unmanaged artificial Pinus koraiensis area and restoring management target area includes managed artificial Pinus koraiensis.

      • 폐주불사를 혼입한 콘크리트의 내구성에 관한 연구

        김태경,박정호,이정호,이주형,박제선,김연경,윤경구 강원대학교 석재복합신소재제품연구센터 1998 석재연 논문집 Vol.3 No.-

        콘크리트 구조물은 자연적인 혹은 인위적인 온도의 상승, 강하로 인하여 동결-융해 작용을 받게 되어 구조물의 성능저하를 야기시킨다. 현대에 들어서면서 콘크리트의 내구특성을 파악하기 위한 연구적 요구가 증가되고 있다. 따라서 폐주물사 콘크리트를 실제 구조물에 적용하기 위해서는 내구특성에 대한 연구가 반드시 이루어져야 한다. 폐주물사를 혼입한 콘크리트의 내구특성을 파악하기 위한 동결-융해 실험은 폐주물사의 잔골재 치환율, 물-시멘트비, AE제 사용 여부를 주요 변수로 하여 실시하였다. 원형공시체를 제작하여, 동결-융해 시험기에 넣어 -18∼4℃로 급속 동결-융해를 진행시키면서 매 23싸이클마다 동탄성계수를 측정하였다. 실험결과 AE제를 첨가했을 때 물-시멘트비가 적을수록, 폐주물사의 치환율이 클수록 전반적으로 강도가 증가하는 것으로 나타났으며, 물-시멘트비가 증가함에 따라, AE제를 사용한 콘크리트가 동결-융해 저항성이 증가하는 것으로 나타났다. 특히 폐주물사 치환율이 50%일 때가 동결-융해 저항성이 가장 좋은 것으로 나타났으며 그 다음으로 25, 0% 순으로 저항성이 좋은 것으로 나타났다. 따라서 폐주물사 콘크리트가 내구성이 우수한 것으로 나타나 폐주물사를 콘크리트에 재활용 할 수 있는 것으로 나타났다. Concrete structures has been deteriorated by the freezing and thawing due to temperature gap. This study was conducted to evaluate durability of concrete which are increasingly demanded recently. Therefore the research of durability must be executed for application of waste foundry sand concrete real structures. Concrete durability properties incorporating waste foundry sand was performed with the variable of W/C ratio, Sand/Waste foundry sand ratio and Air entrainment-Non air entrainment. Cylinder specimens were made and subjected to freezing and thawing cycle at -18℃ and 4℃. Dynamic modulus of elasticity were evaluated as F/T cycle increase. The results show that strength of concrete is increased the W/C ratio decrease, the Sand/Waste foundry sand ratio increase when the concrete contains AE agent and decreasing W/C ratio and AE concrete makes improved resistance of freezing and thawing improved. Especially, resistance of freezing and thawing is improved by Fine aggregate/Waste foundry sand ratio which is 50%, 25%, 0% in a row. Therefore it is turn out the waste foundry sand could be applied to concrete from the experiment.

        The purpose of this study is to examine the perception levels of staff nurses to the head nurse's role expectation and role performance. Also this study is to examin the relationships between the age, education levels, career and satisfaction to the head nurse's role performance of staff nurse's generally and the head nurse's role expectation and role performance. This study was based on 299 staff nurses who work in two university hospitals in Chungnam and JonBuk and in three general hospitals in Chungnam. The data was collected through questionnaires from August 1st to August twentieth, 1989. Data analysis included Mean, S.D(standard deviation), percentage and paired t-test. The findings of this study are as follows: 1. There were significant differences between the head nurse's role expectation and role performance and the head nurse's role items(P<.001). 2. There were significant differences between the appreciation by the staff nurses of the head nurse's role expectation and her role performance. (Direct patient-care role, patient-care management role, nursing staff management role, operational management role, role of education and study.) (P<.001). 3. The relationship between the general characteristics of respondents and the head nurse's role expectation and role performance 1) There were significant differences between the statl nurse's age and the head nurse's role expectation and her role performance(P<.001). 2)There were significant differences between the staff nurse's educational levels and the head nurse's role expectation of them and their the role performance including the nursing college and nursing university (P<.001). (except for the graduate school) 3) There were significant differences between the staff nurse's actual career and the head nurse's role expectation and role performance (P<.001). 4) There were significant differences between satisfaction with the head nurse's role performance and her role expectation and role performance (P<.001) (except for the "very satisfied" group.)
