  • The use of zoysiagrass (Zoysia japonica Steud.) in the transition zone is limited because of a lack of cold hardiness although zoysiagrass has many advantages compared to other warm-season and cool-season grasses. Late-fall N fertilization is often applied for darker green color of turfgrass in early spring and more extensive root growth without rapid top growth. The objective of the study was to evaluate the effects of late fall N application and turf cover for zoysiagrass spring green-up. Clear polyvinyl chloride (PVC) film was used for turf cover. The amount of N applied were 5 and $10g\;N\;m^{-2}$ for the low and high N rate treatments, respectively. Covered zoysiagrass had greater turfgrass color and quality in early spring than non-covered zoysiagrass. The high N rate had 0.6 to 2.3 greater turfgrass quality than the low N rate on 7 of 9 rating dates. Slow-release N as late fall fertilization is more effective for turfgrass color and quality than fast-release N in spring. Turf cover could reduce the period of yellow zoysiagrass, and the earlier time of spring green-up could be advanced by increasing turfgrass quality and growth of zoysiagrass.

  • There are plenty of ecological and traditional resources around Wandong and the Hwangryong-River district, and so the purpose of this development plan is to preserve ecological resources and traditional culture, and to utilize potential value of recreation in this site. Two major concepts are established in this plan one is “Green-Tourism”, the other is “Blue-Recreation”. In this development plan “Green-Tourism” means the effective tourism using ecological and traditional resources, while “Blue-Recreation” means the active tourism using waterfront and cultural facilities. The concept of “Green-Tourism” is applied to the Wangdong area, which is comprised of 6 theme zones. The concept of “Blue-Recreation” is applied to the Hwangryong-River area, which is composed of 4 theme zones. In total, 10 theme zones are planned according to characteristics found in the regional surroundings and cultural facilities of each zone.

  • Zoning areas within national parks in Korea are classified into Natural Preservation Zone(NPZ). Natural Environment Zone(NEZ), Settlement Zone(SZ) and Mass Facility Zone(MFZ) based on the Natural Park Act Large-scale development which might cause permanent destruction of natural resources are being done in NEZ which covers 90% of the total natural park area. Thus it is necessary to examine National Park Act which refers the authorized criteria and development activities of NEZ. However, the current environmental impact statement(EIS) does not cover the full impact of the development inside the national park area. Based on these concepts, the study examines the appropriate resources to distinguish the NPZ and NEZ in Mt. Teogyu National Park, then compare the distribution of resource characteristics between two area by using GIS. Through this study, the conclusions are as follows; (1) In terms of scenic resource analysis, the current NPZ does not meet the criteria on the National Park Act Rather, most of the resources which should be located within the NPZ are located within the NEZ. (2) In terms of elevation analysis, Mt. Teogyu National Park, most of NPZ are located on high altitude which is more than l,200m above the mean sea level. Therefore, it shows the elevation is the only criteria for distinguishing NPZ and NEZ. (3) In terms of Degree of Green Naturality(DGN), the second forest areas, the eighth grade of DGN in Mt. Teogyu National Park are distributed much more in the NEZ than NPZ. (4) After examining five factors - scenic resources, elevation, slope and DGN, vegetation- it was found out that zoning of Mt. Teogyu National Park is not adequatly designated. Zoning of national parks should be accomplished based on the precise inventory of the current resources.

  • Saemangeum reclaimed area is needed to construct much green zone to make high-quality multi-functional land such as tide embankment, lake dike, industrial complex, environmental spaces, etc. However, growth of plants is somewhat difficult because a salinity of Saemangeum soil is very high and a soil fertility, water content of soil are low. Therefore, it is essential to initial desalination of soil and continuous management for planting base. It is recommended that a group of grassland to raise the efficiency of covering should be made in the first stage and a forest by improvement of vegetation should be made in the mid and long term stage. It is recommended that the construction of vegetation base should be made with a regular thickness of soil of good quality in multi-functional area such as a shrub and wood. In case of construction of a windbreak forest, it is necessary to make a wood base of suitable depth using soil brought from another place or filling of soil. Also, it is necessary to keep a maintenance of woods in early stage. Saemangeum reclaimed land will be brand-named worldwide tourist attractions due to construction of much green zone having high quality multi-functional facilities.

  • The impermeable area on the surface of city has been increased as buildings and artificial landcover have continually been increased. Urban development has gradually decreased the green zone in downtown and alienated the city from the natural environment on outskirt area devastating the natural eco system. There arise the environmental problems peculiar to city including urban heat island phenomenon, urban flood, air pollution and urban desertification. As one of urban plans to solve such problems, green roof system is attracting attentions. The purpose of this study was to investigate the heat reduction effect according to the development of green roof system and to quantify the heat reduction effect by analyzing through simulation the heat environment before and after green roof system. For thermal environment analysis, Thermo-Render 3.0 was used that was developed by Tokyo Industrial College to simulate. The simulation showed that the heat island index before and after the development of tree-planting on rooftop changed maximum $0.86^{\circ}C$ and the surface temperature changed about $20^{\circ}C$. Only with lawn planting, heat reduction effect was great and it means that the green roof system in low-management-light-weight type is enough to see effect. The simulation identified that only lawn planting for green rooftop brought such difference and could lower the heat island index at a narrow area. It is judged that application of green roof system to wider areas might relieve urban heat island phenomenon positively.

  • The Jangsan Quartzite is a basal unit of the Cambro-Odovician sequence, in Socheon-Myeon, Bonghwa-Gun, Gyeongsangbug-Do, South Korea, was petrologically and geochemically investigated. The quartzite consists mainly of quartz and muscovite, assosiated with tourmaline and graphite. The quartzite shows white and/or gray color and various green color in hand specimens. The white and gray colored rocks have very low vanadium contents, but a dark green colored rock contains 8960 ppm vanadium. The muscovites in the quartzite show colorless and green color, of which green ones range from pale blue green to pale green. The dark green colored muscovites have above 8 wt. % vanadium and pale green ones have 1-3 wt. % vanadium. Vanadium contents in moscovite increase with decreasing $Al^{v1}$ contents. It suggests that vanadium substitutes for octahedral aluminium in moscovite. In general, it tends to large volumes of muscovite (up to 14 modal %) in deep green colored rocks, and high vanadium contents in their muscovites. Most of the moscovite flakes occur along the quartz boundaries and some are enclosed by quartz grain. The moscovite grains intergrowth each other in the former. The mouscovite aggragates are divided into two types on the basis of their intergrowth(cut) times. Two cut times and one cut time are named T type and D type, respectively. The T type is mainly distributed at western part (near of the Chunyang granite), whereas the D type is distributed from middle to estern part(near the Janggunbong) of the formation. The boundary is consistent with metamorphic isograd between andalusite and sillimanite zone by Ahn et. al. (1993).

  • This study was designed to observe the effect of green tea on colon tumor incidence and biomarkers of colon carcinogenesis in 1, 2-dimethlhydrazine-treated rats. Male Sprague Dawley rats at 7 weeks of age were divided into two groups: control and green tea(GT) groups. Control rats had distilled water as drinking water but GT group received green tea extracts(2.5%, w/v water) as drinking water throughout the experiment periods. All rats were fed the experimental diet containing 15% fat by weight for 20 weeks. and were i.m. injected with DMH for 6 weeks to give total dose of 180mg/kg body weight. Tumor incidence was reduced in GT group (39%) compared with control group (56%) Green tea significantly reduced cell proliferation (total cells per crypt, crypt length and proliferative zone) in colonic mucosa and also significantly reduced the levels of preformed prostalandin E2(PGE2) and thromboxance B2(TXB2) in colonic mucosa but the fatty acid profile of total lipid in colonic mucosa was not significantly influenced by green tea. However the relative percent of C20:4 and the levels f preformed PGE2 and TXB2. were significantly higher in tumor tissue compared with normal surrounding mucosa.Green tea increased the fecal excretion of total bile acid but not scondary bile acid which is known as one of promoters for colon cancer,. These results suggest that green tea could have preventive effect against colon cancer when consumed daily by influencing on antioxidant effect and the metabolism of arachidonic acid.
