용출구조를 보이는 티탄철석-적철석 광석시료에 대한 구조분석을 리트벨트법을 이용하여 시행하였다. 구조유사체인 두 광물의 분석결과, 기본구조인 팔면체의 형태는 티탄철석의 Ti를 중심으로 한 팔면체(M2)가 정팔면체에 가장 가까운 형태를 보여주며, 다음은 티탄철석의 Fe를 중심으로 한 팔면체(M1)이다. 적철석 팔면체의 경우 M1과 M2 중간정도이다. 고압실험은 두 광물의 회절선이 중첩되는 5.8 GPa까지 시행하였다. 이 압력구간에서 티탄철석은 정상적인 압축성을 보이나, 적철석의 압축은 미미하게 발생하는 비정상적인 거동을 보인다. 이러한 이상거동은 두 광물의 압축성 차이에 의한 차등대응에 의한 것으로 판단된다.

Recently, new concept and paradigm of 'Environmentally-Friendliness' is taking a growing interest in environmental planning and design. This study is to establish the evaluation model for environmentally-friendliness of 'Tourism Farms' in rural areas by LISREL structural equation model. A questionnaire survey was conducted for deputy manager group and expert group. As the Result of LISREL structural equation model, the environmentally-friendliness of tourism farms is composed of three categories. First, conservation of global environment (Low Impact), second, friendliness to surrounding nature(High Contact), and third, environmental health and amenities (Health & Amenity). Five indicators, such as (1)saving of energy and water resource, (2)reduction and reuse of garbage, (3)natural purification of sewage disposal, (4)utilization of natural energy, (5)campaign and education programs of environmentally-friendliness, were affecting the first category, i.e., conservation of global environment(Low Impact). Friendliness to surrounding nature (High Contact) is affected by 3 indicators, (1)contact to nature and diverse green areas, (2)water intimate & contact areas, (3)natural ecology observation by biotope. Finally, the dimension of environmental health and amenity is affected by 3 indicators, (1)nature affinity by farming experience, (2)environmental-friendliness of soil & crops by organic farming, (3) campaign and education programs of environmentally-friendliness. Total coefficient of determination of the structural equation model by LISREL was 0.897, which showed high explanatory power.
