This experiment was carried out to compare the cultural characteristics of mycorrizal fungi associated with Pinus species, and to form mycorrhizal association with Pinus thunbergii by artificial inoculation of these fungi. Mycorrhizal fungi tested showed great variations in cultural characteristics. Most fungal isolates was best grown on MP medium, except PDA for Lepista sp.(Ln73/92). Hagem for Rhizopogon rubescens(FRI91017), and FDA for Paxillus sp.(Pa60/92). Optimum temperature for these fungi was $25^{\circ}C$, except $30^{\circ}C$ for Pisolithus tinctorius(FRI91004 and Pt1). The range of pH conditions favorable for these fungal isolates were also variable from weak acidic(pH5) to weak alkalic(pH8). Utilization of the carbon sources for these mycorrhizal fungi was different. Fructose, glucose, and maltose were all utilized well, while xylose was not utilized generally. Mycelial growth on the media supplemented with potassium nitrate was better than those on other media with urea, asparagine, or peptone as a nitrogen source, and the poor growth was observed on the media with urea. Pisolithus tinctorius(Pt1) among 7 mycorrhizal fungi artificially inoculated for the mycorrhizal synthesis on pinus thunbergii seedlings in the test tube containing a mixture of peat moss-vermiculite(2:1, v/v) formed mycorrhizae successfully after 3 months. P. tinctorius formed branched and unbranched roots covered with thick fungal mantle and radiating extemal hyphae. Mycorrhizal root cross-sectioned by hand, stained, and observed by Nomarski interference microscope showed typical characteristics of ectomycorrhizae: fungal mantle on epidermal cells and thick Hartig net hyphae around cortex cells.

This study aims to, first, classify the approach system of utilizing national and local amenities into three groups: evaluation of the level of the amenity, evaluation of the value of amenity resources, and utilization of amenity resources. Secondly, the study aims to derive an evaluation index which is required according to the approach system. As for a strategy of utilizing amenities, the self-diagnosis based on the evaluation of the level of local amenities is required. In this study, three sectors, ten items and 43 detailed items have been derived though specialists, FGIs(Focus Group Interview), and the cases within and outside of the country. In the survey with specialists, a unit-space key index which can be used in accordance with the unit-space characteristics(such as urban and rural area, fishing villages, mountain villages, and littoral areas), environmental area, important index and optional index have been derived. As for the evaluation index which is needed for the development of typical local amenities resources, 14 detailed evaluation indexes from three sectors have been derived. These have been classified again into six key indexes, six important indexes and two optional indexes. In the evaluation index of amenity resources, natural and environmental value-such as ecological value of preservation, uniqueness of aesthetic landscape and ecological value of restoration-historic and cultural value of preservation and individuality of the resources, and aesthetic and cultural values are derived as being important. As for utilization of amenity resources, 15 items from three sectors-such as reservation, restoration, intentional use, and industrial use-have been derived. Also, through a survey with specialists, key indexes and important indexes were derived by unit-space. As a result, in urban areas, seven items-including creative development of space, aesthetic landscape control and development of cultural contents-have been derived as key indexes; in rural areas, mountain villages, fishing villages and littoral areas, eight items-including brand of region, brand of the products, and brand of tourism resources-have been derived. In environmental areas, six items-including reservation of natural resources, historic and cultural heritage, and restoration of ecosystem-have been derived. Indexes derived from this study can be utilized in order to establish a strategy for amenity plans and an implementation strategy, but can be readjusted, allowing for various regional characteristics. It is, thus, advisable that local governments selectively utilize indexes according to regional characteristics or newly develop them for the maximum utilization of regional amenities.

This study aims to present the basic materials, which lead us to preserve the Korea Rice Terrace as scenic sites resources and study it continuously, through researching about the present status and the preservation method of the Rice Terrace in Korea, China and Japan. The results of this study are as follows. First, The Rice Terrace has a traditional agricultural technique which minimizing the damage of the scenic view while cultivating the slope. And also, it has the value of one of the Korea unique traditional scenic views. However, The no cultivation land or disappearing desert land of rice terrace were increasing by the disadvantage of operation in land cultivation. Therefore, The Government must need preparing the base of scene resources excavation by executed the established of Korea Rice Terrace Database for preserving of Korea traditional scene. however it is getting to disappearance. And also, The High valued of Rice Terrace by cultural and scenic view which is must managed by designation of scenic sites or monument. Second, The internal and external reference book researched and analyzed results are as followings for understanding about Korea Rice Terrace feature. First of all, The Rice Terrace's dictionary meaning is just difference by each nations. However, Generally speaking that It means the terraced land by cultivated of sloped land. The Rice Terrace has cross relation with mountain valley and piedmont slope cultivation in location of condition. It occurred era is before approximately estimated from 3000 of years until 6000 of years. It can divide two type by topography shape those are slope and valley type. However, The natural element of forest has very big position in this part. But, The Rice Terrace is just managed and designated by the scenic sites with the Cultural Properties Protection Law. It must needs more binding force and effectiveness for the Rice Terrace scenic view plan establishment by scenic laws and farming and fishing village laws etc. I think that it must need the Rice Terrace related law establishment as soon as possible for efficient preservation and management of the Rice Terrace. Third, The Rice Terrace were researched and analyzed results are as followings those were executed at the Korea, China and Japan. The Korea and Japan have good Rice Terrace Characteristic. And also, The high valued scenic sites area were good managed by the Cultural Properties Protection Law as well as the superior scenic valued Rice Terrace in China. Those are also managed by designated scenic sites for protection and preservation positively. Those were managed by each autonomous district management Department. The each nation's related laws of Rice Terrace protection were just little bit different. However, The basic purpose is same. for example, it based on superior scenic view preservation and protection. Especially, The Japan's Cultural Properties Law and Scenic law linkage, and China Autonomous district legislation and effectiveness. The Korea Government must need above elements for Korea Rice Terrace culture and scenic view preservation. Fourth, We need inducing the owner system and the policy of Rice Terrace preservation promotion association for efficient preservation of Rice Terrace in japan. The owner system in japan gives the owner of the land a permission to rent the land to Rice Terrace preservation promotion association and the local government. In this system the village would be revitalized by commons in the way of the management of the terraces, beautifying the area around the terraces and etc. And also, Making the each village management operating system for Rice Terrace management through educating civilization. The civilization could receive quick help from a consultative body comprised of experts such as representatives of Cultural Heritage Administration and professors. And it is in a hurry to solve the problem of revitalization of the region by exchange between cities and the village.

Jongmyo royal shrine, located in Seoul, is a UNESCO World Heritage site, and a cultural relic of national value and significance. Examination of its udobakseok(granitic flagstone; thin, flat and even stepping-stones for the King) has shown that parts are in damaged condition. In this study, GIS and GPS technologies were applied to determine the extent of damage and to find granitic flagstone for replacement and restoration of the damaged stones. 1,158 out of 2,361 stone pieces of the udobakseok were damaged at Jongmyo. Replacement granitic flagstones are available on Seokmo Island, in Ganghwa County, and estimates show that approximately 100,000 pieces of stone can be quarried. This research aided the systematic management of information about availability and location of granitic flagstones for restoration of the Jongmyo udobakseok. It also demonstrated that GIS and GPS technologies can apply a critical role in managing cultural properties. The wide use of GIS and GPS technologies can be expected for survey and management of other cultural properties in addition to Jongmyo.

Botanic gardens are steadily increasing based on people's increased interests in environment and ecology, lengthened leisure hours and improved transportation. However, similar florae and undifferentiated display are considered as problems, while their functions, purposes and characteristics have been more diversified. This study aims to investigate the present conditions and problems of display at botanic gardens and to find out solutions to make them exhibit plants through various ways of display and have their own characteristic, through a case study of seven botanic gardens. As botanic gardens are being recognized as a cultural institution, they should have limitations in the aspect of places that simply collect and exhibit rare plants. The current problems are unclear setting of design goals and communication with visitors. The gardens should escape from the existing supplier-oriented view to a visitor-oriented view, thinking about what the visitors will be able to see and get there. In particular, their display lacks differency, aesthetics, eye-level display, and multi-layered display. In addition to the essential functions of collecting the world's plants, exhibiting them according to purposes and giving scientific learning, botanic gardens should also show a sense of seasons with plants, trigger interests and amusement through unique plants, make visitors more interested in florae and closer to plants, and include social functions. Botanic gardens should be capable of leaning resources display, speciated display, complex and convergent garden-type display, and display fit for local and cultural contexts.

Seochon('West Village') is located in the west side of Gyeongbokgung(Gyeongbok Royal Palace) inside the old city wall of Seoul. Seochon has beautiful scenic view surrounding Mt. Inwang and has been known as the representative historical and cultural landscape region in Korea that historical and cultural resources are rich. But when the figure of Seochon which has repeated the changes with the ones of the times is considered, values of beauty of natural landscape that Seochon had and its own placeness have not been gradually recognized as it has been swept away in logic of the development on the strength of economics. This study tries to examine the original form of landscape on Seochon which can be the standard of landscape change, the causes and process of its change and possibility to conserve and restore it to recognize potential value about historical culture of Seochon landscape and conserve and protect it. For this, this study compared and analyzed literature including poems and Yusangi, paintings and names of the scenery of the seasons as the landscape texts with the current status. The study result has found that Pilwundae should rehabilitate cultural assets to secure the prospect right and protect neighboring bedrock, Suseong-dong should expand the restoration areas focusing on the projects to make parks which are now being restored, Cheonghwigak and Cheongpunggye areas should restore waterways including historicity which is connected to figures and Seshimdae and Baekun-dong green zone should set the protective area for conservation.

This study was conducted to isolate and characterize a novel feather-degrading bacterium producing keratinase activity. A strain K9 was isolated from soil at poultry farm and identified as Xanthomonas sp. K9 by phenotypic characters and 16S rRNA gene analysis. The cultural conditions for the keratinase production were 0.3% fructose, 0.1% gelatin, 0.04% $K_2HPO_4$, 0.06% $KH_2PO_4$, 0.05% NaCl and 0.01% $FeSO_4$ with an initial pH 8.0 at $30^{\circ}C$ and 200 rpm. In an optimized medium containing 0.1% chicken feather, production yield of keratinase was approximately 8-fold higher than the yield in basal medium. The strain K9 effectively degraded chicken feather meal (67%) and duck feather (54%), whereas human nail and human hair showed relatively low degradation rates (13-22%). Total free amino acid concentration in the cell-free supernatant was about 25.799 mg/l. Feather hydrolysate produced by the strain K9 stimulated growth of red pepper, indicating Xanthomonas sp. K9 could be not only used to increase the nutritional value of chicken feather but also a potential candidate for the development of natural fertilizer applicable to crop plant soil.

A cross sectional analysis for residential water demand was conducted to help understand and explain the spatial and temporal variations in per capita water use in the rapidly growing city of Riyadh, Saudi Arabia. The analysis was based on data previously collected from May 1983 to June 1984. 195 randomly selected households were distributed to three groups according to house condition, household income level, and social and cultural factors. The generated models using stepwise multiple regression indicated that plot size and number of males, females and children are the most significant independent variables. Although, coefficients of determination achieved for most of the developed models were low (0.2-0.5), the independent variables could still explain a part of the variations fur such a complex social and cultural structure.
