전남지방 분포한 Pisolithus tinctorius 분리균주의 생장과 형태적 특성
오광인,박좌식 한국임학회 1989 한국산림과학회지 Vol.78 No.1
전라남도 地域에 소나무 林地에서 分離한 모래밭 버섯菌 5個 菌株와 美國 菌根硏究所로부터 分讓받은 Super Strain #250 등 6個 菌株를 MMN agar 및 Solution 培養後 海松盆苗에 接種하여 各 菌株의 生長 및 形態的 特性을 比較하였다. 生長特性은 純粹培養時 6個 菌株間 Colony 直徑과 乾重量을 比較하였으며 形態的 特性은 海松盆苗에 接種한 後 菌根形態 菌根數 菌根直徑 그리고 細根 및 菌根의 幹과 枝를 광학 顯微鏡으로 測定하였다. MMN배지에서 美國菌株는 國內菌株보다 生育이 良好하였으며 國內 5個 菌株中 Goksung Ⅲ이 特히 生育이 떨어졌다. 盆苗에 接種時 各 균주간 有意的인 差異가 認定되며 純粹培養과는 對照的으로 Goksung Ⅲ가 菌根形成率 및 菌根數가 크게 增加하였으나 菌根長은 짧았다. Haenam Ⅲ은 美國 菌株보다 菌根길이가 길고 Kwangju Ⅰ은 菌根直徑 및 菌의 幹長이 增加하였다. 또한 純粹培養에서 生育이 比較的 旺盛한 Muan Ⅲ. Holtong Ⅱ는 菌根數 및 菌根 形成率이 낮아 純粹培養에서의 生長과 菌根形成能力間에는 直接的인 關係가 없었다.

This study verified the effects of rural tourism service quality on satisfaction, revisit intention and flow's mediating effect. As a result, it were rurality and reliability that rural tourism service quality‘s factors effects tourist's flow. And satisfaction, revisit intention increased as tourist's flow increased. Flow had a complete mediation effect between rurality and satisfaction, revisit intention. In addition, flow had a partial mediation effect between reliability and revisit intention. In other words, consumers want rural tourist destinations to be more rural and have the expertise to give them trust. Therefore, It is necessary to investigate what consumers want to be rural amenity and to consider what is important to gain consumers' trust.

This study was carried out to investigate composition and distribution of the soil microarthropods in Pinus rigida plantations following strip-cutting from May 1998 to Apil 1999. The results of this study were as follows; 1. The individuals of soil microarthropods found during the research periods were 181, 904 and were identified into 21 orders in 7 classes. The classes were Arachnida, Insecta, Malacostra, Pauropoda, Diplopoda, Chilopoda and Symphyla. 2. The population density of the soil microarthropods was 82,962 individuals at the control area, 62,688 individuals at the reserve area and 36,254 individuals at the cutting area. The microarthropods in the control area were 2 times higher than those in the cutting area. 3. Although the major dominant taxa, Acari and Collembola, decreased in densities at the cutting area, the density reduction in Acari was higher than that in Collembola. This resulted in the increase of Collembola in terms of the relative abundance at the cutting area. 4. Among the total soil microarthropods, Arachnida was 59.74%, followed by Insecta of 39.82%. Such two groups comprise 99.56% of soil microarthropods. 5. According to the relative population density, Acari was 99.18% in Arachnida and 59.25% in the total and Collembola 93.99% in Insecta and 37.42% in the total. Therefore, individuals of Acari and Collembola was 96.67% of the total individuals. And the next abundant groups were Hymenoptera (0.95%), Diptera (0.64%) and Pseudoscorpiones (0.39%). 6. The population density of the soil microarthropods fluctuated seasonally, showing the bimodal pattern, being high in fall and spring. The highest density occurred in November and the lowest in July.
日本にぉける觀光農業の經營實態と展開に關する硏究 : 埼玉縣觀光農園の經營を中心に
宋光仁 문화관광연구학회 2000 문화관광연구 Vol.2 No.2
Individual management in Saitama pref. which handles tourism agriculture is analyzed utilizing questionnaire to understand characteristics and issues of tourism agriculture from the viewpoint of its management, and characteristics and issues of tourism agriculture for each classification of agricultural areas are clarified. Characteristics observed are the difference in increase decrease of the number of species, sales forms, the number of tourists, etc. depending on the forms of farms and classification of agricultural areas. Grape farms in terms of the forms of farms and city-like regions in terms of classification of agricultural areas implement and manage more various species. It is also clarified that management by multiple crops has higher agricultural income than management by single crop. Regarding classification of agricultural areas, city-like regions make more efforts to implement various crops than other regions. The higher the agricultural income is, the more number of farms make some kind of changes since opening of farms, including improvement of technology, construction of additional facilities and their expansion, expansion of crops and species, expansion of the area of arable land. Mountainous regions are in severer conditions compared with other regions and require more efforts to these issues.
