  • Reinforcement cells are used to aid grass growth and taken together, this serves to extend greenery beyond the conventional spaces of lawns, tree pits, gardens, and parks, and is advantageous to urban cities since space for greening is often limited. Drought has variable effects on plant life and the resilience of turf to drought resistance also varies with species. Changes in photosynthetic ability were more pronounced for media rather than grass species. The media of sand without organic matter was found to be least suited for drought resistance. Normalized difference vegetation index (NDVI) and digital image analysis (DIA) data were generally in favour of Zoysia species as oppose to A. compressus. In A. compressus, selective traits such as, a more extensive root system and lower specific leaf area (SLA) were not an underlying factor that assisted this grass with enhanced drought resistance. Generally, WUE was found to be strongly related to plant characterises such as overall biomass, photosynthetic features as well as the lushness indexes, and specific leaf area. This study found a strong relationship between WUE and a suite of plant characteristics. These traits should serve as useful selection criteria for species with the ability to resist water stress.

  • The purpose of this study was to investigate children's nutrient intakes by school lunch. Evaluation of nutrient intakes by school lunch for three days was conducted with 86 children in urban and 64 children in rural of Jeonbuk area. The results of this study were as follows. 1) With respect to amounts of provided nutrients in school lunch, CPF (carbohydrate : protein : fat) energy ratio was 48.6 : 19.7 : 31.6 in urban and was 46.7 : 20.5 : 32.7 in rural. Compared to 1/3 RDA (RDA) of children for 10-12 years, folic acid and zinc were provided below 50 % of RDA. Protein, fat, phosphorus, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C and vitamin E were provided above 125 % of RDA. There were no differences in amounts of provided nutrients-except calcium, vitamin A, vitamin $B_6$, folic acid and zinc-between urban and rural. 2) With respect to amounts of nutrient intakes, CPF energy ratio was 51.1 : 17.4 : 31.5 in urban and 47.5 : 19.7 : 32.7 in rural. Compared to RDA, folic and zinc were below 50 % of RDA. Iron and vitamin $B_6$ were below 75 % of RDA. Protein, fat, phosphorus and vitamin E were above 125 % of RDA. There were significant differences in nutrient intakes between urban and rural. The children in rural showed higher levels of nutrient intakes-energy, carbohydrate, protein, fat, calcium, phosphorus, iron, zinc, vitamins and folic acid-compared to those of children in urban. These results suggest that programs are needed for providing adequate nutrient intakes for children in school lunch and for improving nutrient intakes of children in urban.

  • This Paper examines theoretical terrains and design strategies of landscape urbanism which is an emerging hybrid field at the intersection of architecture, landscape architecture, and urbanism. Landscape urbanism offers alternative approaches for theory, education, and practice in contemporary landscape architecture. It views the emergent urban complex sites-post-industrial sites, landfill, brownfield, urban void, etc., not as a weakness, but as a strength. Landscape urbanism poses an understanding of landscape as an element of urban infrastructure. In this sense, the landscape is seen in the context of contemporary urban development and public works. As a complex amalgam, landscape urbanism is more than a design style it is an ethos, an attitude, a way of thinking and acting. We can chart the main characteristics of landscape urbanism such as horizontality and surface, infrastructure, process, technique, and ecology. Multilayered examples of landscape urbanism can be seen in several experimental practices such as worts of Rem Koolhaas, MVRDV, Adriaan Geuze/West 8, James Comer, etc. It is possible to summarize the productive strategies for landscape urbanism as follows : thickening, folding, new materials, nonprogrammed use, impermanence, and movement.

  • Since late 1990's the urban decline phenomenon has risen in most provincial cities in Korea. Many lively discussions have also risen about how to revitalize declined urban center. In small cities, especially resident participation is very important to revive their old vividness. The study then reviewed literatures published from 1995 to 2007 regarding resident participation in urban center revitalization for community reinvigoration. This study consists of four parts. The first part defined concepts of community and of resident participation, and included discussion about resident participation codes. In the second part, the problems about community formation and community facilities were scrutinized through preceding researches. The third and last parts suggested some propositions and strategies to draw resident participation into urban center revitalization.

  • The scale and the extent of a aging of population of a rural are more serious than those of a urban in China. However, the welfare policy and the service for the aged in the rural are inferior. China established the different systems of social welfare policy for the city and the rural and has administered it since the china was established. Owing to an open-door policy(opening of a reform) the gap between the two got more deeply distinguished. Accordingly. the striking difference is shown in a living environment and a quality of life of the cities and the rural. I made clear the difference of services for the aged in the rural and the urban examining daily lives, medical industry, recreation systems and so on and analyzing their sources. In addition, I proposed the ways to establish synthetic social welfare policy of the urban and the rural.
