Seafloor morphology and manganese nodule occurrence were studied in the Korea Deep-sea Environmental Study (KODES) area, northeast equatorial Pacific, to understand their relationship. Study area is composed of three elongated valleys and hills with about 100~200 m height along NNE-SSW direction. Valley region is generally flat. However, hill region is very rugged with big cliffs of about 100m height and small depressions of several tens of meters depth. Tectonic movement along the Clarion-Clipperton fracture zone, consequent formation of elongated abyssal hills and Valleys, erosion of siliceous bottom sediments by bottom currents, and dissolution of carbonate sediments on the abyssal hills below CCD result in the rugged morphology. Manganese nodule occurrence is closely related to the morphology of the study area; mostly rounded-shaped manganese nodules with about 5 cm diameter are abundant on the flat valley region, whereas irregular shaped nodules (or manganese crust) with less than 5 cm to about 1 m diameter occur on the hill. These results supports the previous reports that nodule abundance, composition, and morphology are variable both on regional and local small scales on the seafloor even within some abundant nodule provinces depending on oceanographic characteristics such as bathymetric features, surface sediment type, sediment thickness, and so on. We suggest that such oceanographic characteristics affect interrelatedly on the formation of manganese nodules, and tectonic movement of the Pacific plate ultimately constrain the nodule occurrence. A potential mining place in the KODES area seems to be the valley region, which is elongated to the NNW-SSE direction with 3-4 km width.

Complex terrain refers to irregular surface properties of the earth that influence gradients in climate, lateral transfer of materials, landscape distribution in soils properties, habitat selection of organisms, and via human preferences, the patterning in development of land use. Complex terrain of mountainous areas represents ca. 20% of the Earth's terrestrial surface; and such regions provide fresh water to at least half of humankind. Most major river systems originate in such terrain, and their resources are often associated with socio-economic competition and political disputes. The goals of the TERRECO-IRTG focus on building a bridge between ecosystem understanding in complex terrain and spatial assessments of ecosystem performance with respect to derived ecosystem services. More specifically, a coordinated assessment framework will be developed from landscape to regional scale applications to quantify trade-offs and will be applied to determine how shifts in climate and land use in complex terrain influence naturally derived ecosystem services. Within the scope of TERRECO, the abiotic and biotic studies of water yield and quality, production and biodiversity, soil processing of materials and trace gas emissions in complex terrain are merged. There is a need to quantitatively understand 1) the ecosystem services derived in regions of complex terrain, 2) the process regulation occurred to maintain those services, and 3) the sensitivities defining thresholds critical in stability of these systems. The TERRECO-IRTG is dedicated to joint study of ecosystems in complex terrain from landscape to regional scales. Our objectives are to reveal the spatial patterns in driving variables of essential ecosystem processes involved in ecosystem services of complex terrain region and hence, to evaluate the resulting ecosystem services, and further to provide new tools for understanding and managing such areas.

This research is an introductory study that hopes to interpret the cultural scenic landscape by analyzing Korea's mountains, streams, topography, color, light, human behavior, and more based on real landscape paintings. It places its purpose on understanding our intrinsic cultural scenic landscape by investigating the changed topography and the differing life patterns caused bythe active national land development after the modern era. With Seoul, which is now difficult to find images of its past, and the surrounding areas of the Han riverbed, the interpretation related to its original topography, landscape, climate, weather, and human behaviors was observed while the main focus was placed on the climate of the perception held by people regarding Mt. Geumgang and other ranges which are not fully opened to the public yet. In order to comprehensively analyze the figures of features and appearing landscapes including color, light, and more, it was described through the concept called climate. Hereupon, the real landscape paintings by Gyunjae(Jeong-Seon), mainly bearing features of existing Korean mountains, wereutilized as visual historical material. However, not having all his works, other pieces with representative characteristics were utilized such as "Gyeong-Gyo-Myeong-Seung-Chup(a painting with picturesque sceneries around old Seoul)" and "Hae-Ak-Jeon-Shin-Chup(a landscape painting including even the spirits of the seas and mountains)" which contain the regions' distinct scenery. As a result, the old cultural scenic landscapes of Korea are regarded as containing diverse mountains and where the conceptions of the treatment of mountains were reflected.

The skin is the largest organ of the integument system whose surface is closely related to many physiological and pathological conditions. The skin surface is closely related to functional status of the epidermis and dermis. The outermost surface of the skin shows characteristic pattern defined by small furrows are called micro-relief. The micro-relief change is according to physiological and pathological conditions of the skin. But, there is no data on health Korean skin micro-relief yet. This study presents some aspect of health Korean skin micro-relief from the twenties. The silicon replicas obtained from forearm, dorsum hand and finger were analyzed by profiles were accessed by stereoscopy. We measured density of furrow, width of furrow, and depth of furrow in micro-relief with sectioned silicon replica sample using stereoscope. Stereoscopic analysis showed that male group has a larger density of furrow and depth furrow in finger significantly. The densities of furrow were shown different not only between forearm and finger but also between finger and hand in male with female group. In conclusion, there were differences results between sex different and regional difference in skin replica profile. These quantitative data can be used for basis of further skin research for Korean.
