We give a characterization of regular operators that allows us to prove that a bounded operator acting between Banach spaces is almost regular if and only if it is regular, solving an open problem in [5]. As an application, we show that some operators in the closure of the set of all regular operators are regular.

The purpose of this paper is to introduce two new types of irresolute functions called, completely ${\rho}$-irresolute functions and weakly ${\rho}$-irresolute functions. We obtain their characterizations and their basic properties.

Taegu is notorious as hot and dry summer among Korea cities. One of the most important goals of the open space planning is to ameliorate urban climate of the city. The objective of this research is to evaluate the thermal mitigation effect of the cool islands in Taegu metropolitan city. Cool islands of this paper includes parks and rivers surrounded by or adjacent to urbanized areas. Based on the analysis of the thermal band of Landsat TM at May 17, 1997, the thermal mitigation effect of open spaces in the city could be summarized as follows ; Kumho river showed the largest mitigation effect in terms of the width of mitigation zone and temperature difference. Evaporation from wide water surface and evapo-transpiration from riparian grass land could bring into results. Significant mitigation effect of parks covered with forest can be observed. The temperature range of such parks were between 19.05$^{\circ}C$ and 19.44$^{\circ}C$ However, the thermal mitigation effect of Dalsung park and Apsan park was insignificant. The small size and high percentage of hard paving of the former and the relative low density of the residential areas adjacent to the latter could be the main reason. In conclusion, the thermal mitigation effect in urban ope spaces could be detectedby the employment of thermal band data of Landsat TM and GIS buffering technique.

The purpose of this study is to suggest the basic design elements for dwelling environment planning of downtown in Taegu.The evaluation of the dwelling environment should be approached from the satisfaction and the cognitive of the residents, that are based on their desire and various values on the conditions of residential area. This paper concerns the satisfaction and the congnitive image structure of the residents in the various dwelling types, from which design elements for dwelling environments can be derived. The results are as folIows: 1) The analysis on the satisfaction of dwell ins environment shows lots of displeasure about the lack of open-spaces and the housing low-quality, neighborhood in Mun-hwa, Korean style housing and the low-rise apartment areas. In order to make the variety types of dowelling in downtown district, the improvement of housing qualities and the expantion of the urban facilities for the open-spaces and communities are need. 2) The design elements of dwelling environments in downtown find out the important planning elements for urban design. The evaluation of the cognitive image structures about the safety and affection should be considered in design for urban dwelling areas.

The purpose of this study was to explore behaviors of spatial usages such as patterns of spatial usages, perception on residential spaces, and furniture arrangement. A questionnaire survey and interview were adopted in this study, and 146 residents living in apartment with 3 bedrooms, stairway access, and 3-bay style in the City of Gwangju. The major findings of this study were that 1) dining-kitchen (DK) was conceived and used as a space not only for dining but also family gathering and guest reception. Dining table without refrigerator was frequently found in furniture arrangement of DK, and refrigerator has been relocated in utility room facing DK. The results imply the need for social interaction that has been growing. Anbang (master bedroom) has been perceived and used as couples' private area, aside from the traditional function of family interaction. A coordination of both bed and wardrobe out of different furniture arrangements was popular in anbang. Living room was used as a multi-purpose room carrying out various activities such as family gathering, guest reception, and housekeeping. Sofa and cabinet were the most common furniture arrangement in living room. The research results are a basis for development residential open housing system.
