  • Major studies of Home Economics have had an intention to keep the standard scientific perspective based on value-free and positivism. But in the early 20C there was a change within scientific philosophy and the holistic perspective has risen in the part of scocial and natural science. The phenomenon dealt in the field of Home Economics is the interaction between human and environment and it regards human and family behavior in the context of the environment as a major object. This interaction can be micro/macro and objectiv $e_jective, So it has a very complex trait. The goal of this study is to verify the applicability of Human Ecology as an alternative framework to explain each level of the family phenomena. Further it is concluded that it is very efficient to present Human Ecology as a general theory for Home Economics because there are increasing demands for understanding interdependence and persuing for balanced co-existence between human and encironment. Finally this study concludes that Human Ecology is not a past theory but a very comprehensive one to construct and abstract theory-building.ng.

  • Walnut colorants were extracted from walnut hull and their dyeing properties on cotton were investigated. Effect of dyeing conditions on dye uptake and effect of mordanting on dye uptake, color change and colorfastness were explored. Walnut colorants showed low affinity to cotton compared with wool and its isotherm adsorption curve was Freundlich type. It was considered that hydrogen bonding and van der Waal's force were involved in the adsorption of walnut colorants onto cotton. The dyed cotton showed YR color and there was no significant color change as pH changed. The dyed cotton showed generally high colorfastness except fastness to washing and light. Mordanting did not improve dye uptake and colorfastness, and not affect color of the dyed cotton significantly.

  • Conservation drones are remote-controlled devices capable of collecting information from difficult-to-access places while minimizing disturbance. Although drones are increasingly used in many research disciplines, their application to wildlife research remains to be explored in depth. This paper reports on the use of Phantom 2 Vision+ for monitoring areas in two national parks in South Korea. The first research area was conducted in Chiaksan National Park, and the second in Taeanhaean National Park. The aim of this research is to introduce ecologists and researchers alike to conservation drones and to show how these new tools have are fundamentally helping in the development of natural sciences. We also obtained photographs and videos of monitoring areas within our test site.

  • Cooperative behavior may seem contrary to the notion of natural selection and adaptation, but is widely observed in nature, from the genetic level to the organism. The origin and persistence of cooperative behavior has long been a mystery to scientists studying evolution and ecology. One of the important research topics in the field of evolutionary ecology and behavioral ecology is to find out why cooperation is maintained over time. In this paper we take a historical overview of mathematical models representing cooperative relationships from the perspective of mathematical biology, which studies population dynamics between interacting biological groups, and analyze the mathematical characteristics and meanings of these cooperative models.

  • This study designed to explore the patterns of housing life-styles and the characteristics of apartment housing residents and to examine the relationships between housing life-styles and the characteristics of apartment-housing residents. The data for this study was collected by questionnaires administered to 278 homemakers living in apartment housing over 20s pyong(66$m^2$) in the Kwangju area. The major findings of this study can be summarized as follows; 1. Housing life-styles were grouped into 9 sub-categories : the Anbang-centered, the dining-centered, the pursuit of conspicuosness and conformity, orientation to change, the pursuit of orderliness, the pursuit of decoration, orientation to community, pursuit of individuality and the orientation to a natural environment. 2. Housing life-styles were significantly different according to age, educational background, and employment status of homemakers, occupation of the primary income provider, family-life cycle stage, total household income, and housing size.

  • To develope reforestation methods for enviromentally sound and ecological forest management, Fraxinus rhynchophylla stand structure and radial growth of the trees were invstigated and compared by study sites. Plantation forest studied on Fraxinus rhynchophylla, was located at Jawoon-ni Nae-myeun, Hongcheon-gun and natural forest studied on Fraxinus rhynchophylla, was located at Jangjeon-ni Jinbu-myeun, Pyeungchang-gun. In 7,8 years after planting, differences of annual diameter increment among three stand origins were significant. The highest mean annual diameter increments of F. rhynchophylla, 4.60 mm/year was measured in sprouting trees, and followed by natural seedlings 4.59 mm/year. The lowest values, 4.18mm/year did in planting trees. Early radial growth of planting F. rhynchophylla was measured lower than that of sprouting or natural seedlings. These facts mean that planting F. rhynchophylla is not proper regeneration methods. Other regeneration methods of F. rhynchophylla forest, by sproutings, direct seeding and natural seeding, might be researched and recommended.

  • This study estimated potential natural vegetation in Gayasan National Park through the occurrence probability distribution by using geographic information system (GIS). in Gayasan National Park. Correlation and factor analysis were analyzed to estimate probability distribution. The presence of the Gaya National Park Vegetation survey results showed that 128 communities were distributed. The analyzed relationship between actual vegetation and distribution factors such as elevation, aspect, slope, topographic index, annual mean temperature, warmth index and potential evapotranspiration in Gayasan national park. The probability distribution of potential natural vegetation communities at least 0.3 odds were the advent of Pinus densiflora communities with the highest 55.80%, Quercus mongolica community is 44.05%, 0.09% is Quercus acutissima communities, Quercus variabilis communities are found to be 0.06%. If you want to limit the factors that affect the distribution of vegetation by factors presented in this study, the potential natural vegetation of the Gaya National Park was expected to appear in Quercus mongolica community (43.1%) and Pinus densiflora communities (56.9%).

  • This study was conducted to clarify the characteristics of habitat structure and bird communities between natural deciduous forest and around the road from October 2005 to August 2006 in the National Arboretum, Gwangneung, Korea. There were more larger trees and higher coverage of crown canopy in the natural deciduous forest than around the road. A total thirty seven species of birds were observed in the natural deciduous forest and twenty species were around road. The observed number of bird species and individuals, and bird species diversity index (H') were higher in the natural deciduous forest in each season. Foraging and nesting guild structures were also different. The differences of characteristics of bird communities would be related with habitat structure between both study areas.
