This study has been conducted focusing on the analysis of the turn-key proposal for Gimpo-Han River New City. The study expected that it would come up with design trends and introduction properties of each plan for the eco-friendly development of an apartment house. The concept of environment-friendly design was thought in four parts: 'Land use and transportation,' 'Ecological environment', 'Energy resource and environmental impact' and analysis factors of each part were chosen by specific items from the prospective researches and guidelines that already given on the projects. In conclusion, a proper development of the environmental-friendly apartment house will not be achieved unless the designers try to overcome their prejudice against eco-friendly planning elements applications. Along with the designers' attempt, it is also necessary to review the evaluation articles of the certification system for the existing environmental-friendly structures as well as to compensate and establish detailed evaluation standards. As the problems are being worked on, an integrated, effective evaluation standard for the eco-friendly planning elements will be determined. This way, an environmental-friendly residential development with a better quality will be eventually realized.

This study is focusing on Territoriality which is supposed to be one of the most important elements to activate open spaces in apartment communities. Case analysis with onsite visit is selected as the research method of this study targeting 6 apartment complexes in Bukgu and Gwangsangu, Gwangju city which accommodate over 500 households up to 800 households, which show high occupancy ratio and which were built after 2006 to minimize the physical environment variable. The result of this study is concluded as follows. First, we need the elements which can induce various action and the use of floor surface in color, pattern, and material should be considered in the stance of pedestrian for easy recognition of Territoriality change. Second, To secure the view, we should consider to plant shrubs or to plant trees wider apart. In most cases, enclosure is secured by using trees of Vertical Boundary for safety and comfort, but overuse in some cases make residents feel fear of enclosed spaces and insecurity. Third, Various and harmonious design elements can be recommended to increase aesthetic impression, to induce positive response for design, and to be used consistently. Finally, Unique space using notable landmark or design elements should be considered.

The tectonic evolution of the Central Ogcheon Belt has been newly analyzed in this paper from the detailed geological maps by lithofacies classification, the development processes of geological structures, microstructures, and the time-relationship between deformation and metamorphism in the Ogcheon, Cheongsan, Mungyeong Buunnyeong, Busan areas, Korea and the fossil and radiometric age data of the Ogcheon Supergroup(OSG). The 1st tectonic phase($D^*$) is marked by the rifting of the original Gyeonggi Massif into North Gyeonggi Massif(present Gyeonggi Massif) and South Gyeonggi Massif (Bakdallyeong and Busan gneiss complexes). The Joseon Supergroup(JSG) and the lower unit(quartzose psammitic, pelitic, calcareous and basic rocks) of OSG were deposited in the Ogcheon rift basin during Early Paleozoic time, and the Pyeongan Supergroup(PSG) and its upper unit(conglomerate and pelitic rocks and acidic rocks) appeared in Late Paleozoic time. The 2nd tectonic phase(Ogcheon-Cheongsan phase/Songnim orogeny: D1), which occurred during Late Permian-Middle Triassic age, is characterized by the closing of Ogcheon rift basin(= the coupling of the North and South Gyeonggi Massifs) in the earlier phase(Ogcheon subphase: D1a), and by the coupling of South China block(Gyeonggi Massif and Ogcheon Zone) and North China block(Yeongnam Massif and Taebaksan Zone) in the later phase(Cheongsan subphase: D1b). At the earlier stage of D1a occurred the M1 medium-pressure type metamorphism of OSG related to the growth of coarse biotites, garnets, staurolites. At its later stage, the medium-pressure type metamorphic rocks were exhumed as some nappes with SE-vergence, and the giant-scale sheath fold, regional foliation, stretching lineation were formed in the OSG. At the D1b subphase which occurs under (N)NE-(S)SW compression, the thrusts with NNE- or/and SSW-vergence were formed in the front and rear parts of couple, and the NNE-trending Cheongsan shear zone of dextral strike-slip and the NNE-trending upright folds of the JSG and PSG were also formed in its flank part, and Daedong basin was built in Korean Peninsula. After that, Daedong Group(DG) of the Late Triassic-Early Jurassic was deposited. The 3rd tectonic phase(Honam phase/Daebo orogeny: D2) occurred by the transpression tectonics of NNE-trending Honam dextral strike-slip shearing in Early~Late Jurassic time, and formed the asymmetric crenulated fold in the OSG and the NNE-trending recumbent folds in the JSG and PSG and the thrust faults with ESE-vergence in which pre-Late Triassic Supergroups override DG. The M2 contact metamorphism of andalusite-sillimanite type by the intrusion of Daebo granitoids occurred at the D2 intertectonic phase of Middle Jurassic age. The 4th tectonic phase(Cheongmari phase: D3) occurred under the N-S compression at Early Cretaceous time, and formed the pull-apart Cretaceous sedimentary basins accompanying the NNE-trending sinistral strike-slip shearing. The M3 retrograde metamorphism of OSG associated with the crystallization of chlorite porphyroblasts mainly occurred after the D2. After the D3, the sinistral displacement(Geumgang phase: D4) occurred along the Geumgang fault accompanied with the giant-scale Geumgang drag fold with its parasitic kink folds in the Ogcheon area. These folds are intruded by acidic dykes of Late Cretaceous age.
