The constant evolution of society, culture and scientific technology, coupled with changes in life style and behavioral patterns, has led mankind to peroeive diverse needs for space. Particularly, the rapid structural change in the field of marketing has entailed changes in techinques for construction and presentation of space for an improved marketing environment. To satisfy such new, diverse needs for space, interior designers will have to redefine the "mankind and environmen( concept and examine their design methodology anew. The question of how to design available space for a certain purpose will remain a daunting task for designers in the future, as it has been in the past. In the pursuit of convenience and conformity to mankind's surroundings, every nation has, in common with other nations, basic design elements, design skills and other factors. In designing camercial space in a particular region, it is essential, however, to have a proper understanding of the social economic and cultural context indigenous to that region, as well as the impact on environmental and ecological change and marketing strategy. This study discusses design metholdology for the comming camercial space on the basis of the space concept and current status in Korea, with major emphasis on Korea's regional characteristics.

It is difficulty to calculate velocity circulation in centrifugal pump impeller outlet accurately. Velocity circulations of a double-blade pump impeller outlet were calculated with Stodola formula, Weisner formula and Stechkin formula. Simultaneously, the internal flow of impeller for the double-blade pump were measured with PIV technology and average velocity circulations at the 0.8, 1.0 and 1.2 times of design flow were obtained. All the experimental values were compared with the above calculation values at the three conditions. The results show that calculation values of velocity circulations with Weisner formula is close to the experimental values. On the basis of the above, velocity circulations of impeller outlet were corrected. The results of experimental verification show that the corrected calculation errors, whose maximum error is 3.65%, are greatly reduced than the uncorrected calculation errors. The research results could provide good references for establishment of theoretical head and multi-condition hydraulic optimization of double-blade pumps.

This study aims to analyze the hair styles featured in the collections from S/S season of 1995 to F/W season of 2004 both qualitatively and quantitatively by using content-analytical methods. This study was able to form a classifying system that divides hair styles into those artificial and those natural through systematic and scientific research. The resulting system, in turn, broadened the basis for understanding modern fashion and hair style expressions. In addition, by analyzing design-related characteristics, certain expressive techniques employed, and trends in detail, this study contributed to establishing the hair styles, which form part of socio-cultural phenomena, as an academic subject.

The purpose of this study was to investigate elementary students' difficulties when they read the illustrations on scientific textbook. 5 illustrations were selected on basis that they had some of the textual/graphical features. The data were collected from open-ended questionnaires and follow-up interviews. To investigate difficulties of reading illustrations, 100 sixth grade students participated in this study and interviews were taken to 9 volunteers among those participants. The results showed that many students had difficulties in the integration of verbal representation and realistic image representation on the illustration, therefore they often misunderstood the meaning of illustration. These results gave several recommendations when we used illustrations as educational materials. Teachers would be better to guide that students could understand illustrations with the integration of the reading of one or more representations.

Advanced adhesive technologies and demanding applications of adhesive joints can no longer be developed successfully by the traditional "trial and error" approach. Appropriate technical solutions require reference to a reliable basis of well-established scientific knowledge about the elementary mechanisms of adhesion (i.e. the 'fundamental adhesion') as they are responsible for the capability of the compound w transmit mechanical force between the adhesive and the substrate surface (i.e. the 'practical adhesion'). Adhesion mechanisms also influence the formation of polymer structure in the adhesive and the resulting macromolecular dynamics in the interphase that is formed in the adhesive near to the substrate. These manifold molecular factors rule the macroscopic behaviour of an adhesive bond line in terms of mechanical and other physical properties as well as in terms of durability. This paper reviews the level of refinement that understanding of fundamental adhesion has achieved up to now.

This study was made on the taxa Chrysanthemum zawadskii complex that grow in South Korea on the basis of chromosomes, epidermis, pollens and gross morphology. I have found four types of chromosome numbers, 36, 45, 54, and 72 as a polyploidal series. Even though the gross morphology was quite similar almost the same gross morphology, chromosome number was different among the taxa. The taxa of 36 chromosomes present broad and fine lobed leaves which grow separately, broad leafed taxon in the mainland of Korea and the other's in Ullungdo Island which is isolated form the mainland in the East Sea. The taxa of 54 chromosomes are also present in the broad and in the fine lobed leaves. The fine lobed leave taxon grows in central to northern Korea and in the high altitude of mountains. Broad leafed taxon grows in central to southern Korea and comparatively lower altitude of the mountains. The taxon of 72 chromosomes is grown in the high altitude of Mt. Hallasan which is isolated from the mainland of Korea. According to this study of Chrysanthemum zawadskii complex, I have arranged the scientific names, as Chrysanthemum zawadskii subsp. latilobum, subsp. acutilobum, subsp. naktongenese, subsp. lucidum, subsp. coreanum and hybrid between subsp. acutilobum X subsp. latilobum.

This paper aims at investigating the realities of puerperal period of Korean women, chiefly in the city of Seoul, on the basis of their living standard, schooling caree by age groups, to contribute to the improvement in health of mother and child. In this paper in which the writer, aming 492 women in Seoul a subject of this investigation and giving them 34 items of questionnaires, has studied their concern and practices to recover their health during a lying-in period, and drawn a conclusion as follows : Though their place of childbirth and food they take during the period are varied according to their standard of living, their practices and managements after parturition are true to the conventional usage which is far from modern scientific methods. Problems for the better management during puerperal period are : 1. to have expactent and nursing mothers better educated in their antenatal care ; 2. to let the family planners have more understanding about the problems of puerperal period ; 3. to make those who are concerned study on the problems interdependent between puerperal period and pregnancy and child birth.
