This research starts from the questioning of current housing development situation on hilly sites in Korea. It aims to investigate various design techniques of row-rise housing as an alternative housing type on hilly sites. Several generic solutions are proposed by considering the density of dwelling, parking plans, exterior space and access patterns, making full use of geographical features of hilly site and existing facilities. In order to promote development feasibility of proposed plans, the efficiency of the proposed techniques are verified in terms of development density, enhancement of community space, habitability of housing.

The purpose of this study is to find how to use the terrace-house which can protect development thoughtless for the environment of hilly sites and make good hilly residential area. But there are some problems not to be able to apply terrace-house on hilly sites under such korean circumstances. So, to find these problems, it is analyzed different things between terrace-housing and high-rise apartment housing. This analysis finds some reasons why terrace-houses can't be applied in korea. Of these reasons to interrupt application of terrace-house, this study is to solve problem of density and to suggest the design proposals considered by habitability.

This research starts from the questioning of current housing development on the hilly site in Korea. It aims to investigate various design techniques of low-rise housing as an alternative housing plan on hilly sites. Several generic solutions of the combination of building type and road pattern are tested for a simulation process, and evaluated in terms of crucial design issues; development density, parking space and open space. As a result, four reasonable models are selected for making full use of geographical features of hilly site, two models each land slope of $18^{\circ}$ and $26^{\circ}$. Several design techniques for each model are also suggested, in ensuring the development feasibility by considering land slope, vehicular access and parking, common open space, and community facilities.

This research starts from the questioning of current housing development situation on hilly sites in Korea. It aims to investigate various design techniques of terraced housing as an alternative housing type on sloped sites. Several generic solutions are proposed, as for site slope and stacking method, combination of dwelling units, access pattern, and sectional variation of unit space. By the comparative analysis of design proposals with the typical two-row vertical-access type, the efficiency of the proposed techniques are verified in terms of development density, provision of community space, habitability of dwelling units.

This study was aimed at analyzing the location and the characteristics of the Urban hanok tissues that were formed in the downtown since 1920s. Focusing on the relationship between roads and lots, the developing process and the typological characteristics are examined. Through dividing the large and medium lots of the aristocratic families and on the hilly area near the Seoul City Wall, various shapes of urban hanok tissue were evolved. The urban hanok tissues developed before 1936 locate on the downtown sites, while those developed after 1936 locate on the hilly sites. The location of the tissues were identified in the upper area of Jong-no street. The former is composed of small size lots divided into average area $104.4m^2$ with the narrow alleys of about 2.0m width, while the latter is composed of medium size lots divided into average area $131.54m^2$ with the alleys of about 4.0m width. Moreover the structures of the tissues were evolved based on the developing period and the site condition. Moreover the structures of the tissues were evolved based on the developing period and the site condition. The typological characteristics were defined as the four patterns categorized with the bilateral concepts of alley's form and of alley's spacial feature.

The aim of this study was to collect the basic data for effective creation and management of hilly pasture. The investigation of flora and vegetation was conducted at 59 $relev\acute{e}s$ in hilly pasture of Daegwallyeong from 2014 to 2016. The vascular plants of the hilly pasture were 121 listed taxa which contain 38 families, 90 genera, 104 species, 13 varieties, and 12 subspecies. The biological type of the hilly pasture was determined as the $Th-D_4-R_5-e$ type. Twelve taxa were of naturalized plants composed of 5 families, 9 genera, 12 species. The urbanization index and the naturalized index were 3.7% and 9.9%, respectively. The vegetation types in the hilly pasture were classified into the following 3 communities: the Spiraea miyabei-Spiraea salicifolia community, the Persicaria thunbergii community, and the Agrostis alba-Phleum pratense community. The Agrostis alba-Phleum pratense community was classified into the following 5 subcommunities: the Poa pratensis subcommunity, the Artemisia princeps subcommunity, the Festuca ovina subcommunity, the Rumex acetosella subcommunity, and the typical subcommunity. Two factors (slope and EC) had the strongest impact on plant community distribution. Especially, the steep sloping sites (over $40^{\circ}$) did not play a crucial role in maintaining adequate pasture because of the invasion and establishment of shrubs.

Extractable iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu) contents and their distribution with depths in soils of forested and adjacent deforested areas at Jahazpura, Teknaf, Cox's Bazar of Bangladesh were studied. The soils under forest showed higher levels of DTPA-extractable micronutrients in all three layers of soil in comparison to those of the deforested areas. The differences between forested and deforested sites were, in most cases, significant.. The top soils of forested sites had the higher contents of micronutrient and generally decreased with depth in forested soils, while there was no regular trend of distribution in deforested soils. The study also revealed that contents of extractable Fe, Mn and Cu were sufficient in all depths and sites but Zn was deficient in bottom layer of forested and all three layers of deforested sites. The results suggested that organic matter, clay and soil pH could play important roles in concentrations and distributions of micronutrients in soils of the study areas.

This study looked into 110 sites of orchard fields to investigate the relationships between the physical and chemical properties of soils, including heavy metal contents, and the topographic characteristics of the fields in Jeonbuk province. The topographic distribution of orchard fields in Jeonbuk province was local valley and fans, hilly and mountains, mountain foot slopes, alluvial plains, diluvium, and fluvio-marine deposits. Forty-six percent (46%) of total orchard fields were located in the hilly and mountains. Soil texture of the local valley and fans was mostly sandy clay loam, and the soil texture of other topographical sites were varied. Bulk density, porosity, and soil hardness were not different among the various topographic sites. The content of plant available water was the highest (19.5%) in the sites of diluvium. Soil pH, electrical conductivity (EC), and exchangeable $Mg^{2+}$ content were the highest in the sites of fluvio-marine deposits, whereas the contents of soil organic matter (SOM), available phosphorus, and exchangeable $Ca^{2+}$, $K^+$, and $Na^+$ were not significantly different among the topographic sites. Also, soil pH and SOM content were generally in optimal ranges for the fruit plants in the orchard fields, but other values were mostly higher than those in optimum. In addition, the contents of heavy metals were much lower than the levels of Soil Contamination Warning Standard.
