  • Measuring the river flow and water quality in the midstream of the Nakdong River, the natural purification status in examined through the analyses of the elements which affect the variation of dissolved oxygen, and DO model is evaluated to the midstream reach of the river. The major results of this study are as follows; the pruification factor of the of the river is relatively high, it is worried over eutrophication considering much production of algae, and it is evaluated that important factor affecting the DO value computed by the proposed DO model are in order of reaeration coefficient, carbonaceous BOD and deoxygenation constant.

  • Designers and builders are omitting structural design and relying on workers' experience, due to the lack of awareness of the importance of scaffolding in domestic construction sites, and there is a high probability of collapsing accidents such as inappropriate wall joint installation and non-compliance with work procedures. Therefore, risk factors were analyzed in detail and major risk factors were derived from opinions of site managers and scaffolding experts in this study.

  • Fatigue strength analysis is one of the most important themes of ship structure design, as fatigue damages are reported on ship structures even now. But these need basic research workes which will take time. The others are the problem to apply fatigue strength analysis in design and have to be investigated in parallel with basic researches. The one of major items in the latter is the critical damage factor to define with S-N curve for fatigue strength analysis of ship structure design.

  • The purpose of this study was performed to analyze the trend of bodytype change of adult males. Subjects were 1290 Korean adult males and their age range was from 19 to 54 year, ; old. 75 variables(66 variables from the direct anthropometric data and 9 variables from the multiplication method) in total were applied to analyze. The principal component analysis was applied to the data with orthogonal rotation after extraction of major factors. The high factor loading items extracted by factor analysis were analyzed for the trend of bodytype change by the age group respectively. The result of factor analysis indicated that the first factor was composed with about 30 items, girth, depth and width-measures in 4 age groups and was analysed as form factors. Especially, age-related change was caused by increase of waist girth, depth and width. The second factor was composed with about 23 items, length and height-measures in all age groups. Stature has a constant factor loading value in 4 groups. Front and back waist-height and the navel-height have the highest factor loading value. The third, fourth and fifth factors were composed with different variables among the age groups.

  • This study intends to ascertain the importance of store atmosphere when construcing store marketing strategies for store differentiation. And it is studied by classifying consumer groups according to clothing shopping motivations, comparing store atmosphere assessment and emotion response of preferred stores, and analyzing the influence store atmosphere has on store preference or impulsive purchase. The subject of this study are women in their twenties living in Seoul, 255 career women and 233 college students totaling 458, and model sampling is done by convenient sampling taking into account the type of their occupation and major. Modified survey based on references and former studies is used, and using SAS packages, methods. The results of data analysis are as follows. 1. Consumer groups are classified into the following four subdivisions: shopping involvement, leisure pursuit, financial, and shopping unconcern group. The stores women in twenties use most frequently for shopping are department stores, speciality stores, common market, discount stores, and wholesale markets, and significant difference are shown between consumer groups. 2. Consumer responses for store atmosphere preferences are shown significantly among groups when concerned with store preferences. 3. Images of store atmosphere as factor analyzed into environment factor, kindness factor, and decoration factor, Environment factor is most highly estimated in speciality stores, kindness factor in department stores, and decoration factor in common markets. 4. Leisure pursuit group is assessed to be most influenced by store atmosphere in store seleciton, impulsive purchase, and after-purchase shopping behavior, and impulsive purchase is shown highly in department stores and speciality stores.

  • The aim of this paper is to examine the determinants of residential satisfaction and attachment according to the urban multi-family dwelling types. On the basis of the surveys, the factor analysis and regression are employed as the empirical analysis on residential satisfaction and attachment in Daegu metropolitan city. The major findings are as follows; First, as for post-occupancy evaluation of residential environment of building and outside, the residents of complex type of multi-family housing satisfied with most of items more than studio type except the location, amenity facilities around building and utilities fee. Second, about the Residential Satisfaction and Attachment by types, the residents of complex type of multi-family housing satisfied with most of items more than studio type too. Third, the determinants in residential Satisfaction of complex types are 'welfare and amenity facilities factor', 'maintenance factor' and 'location factor'. On the other hand, the determinants in residents of studio type are 'inexpensive rent fee factor', 'welfare and amenity facilities factor' and 'maintenance factor'. Going forward, this research will help us better understand residential satisfaction from the point of residents and find new ways to improve resident satisfaction and attachment.

  • The purpose of this study was to develop 『Korean Maternal Behavior Inverntory』(KMBI). The subjects were 712 mothers of 4th-6th grade elementary school children from 5 urban cities in Korea. Item analysis. Cronbach's α, Pearson's r, Factor analysis, and Percentile norms were conducted for the purpose of the study. The major findings were as follows; 1. By the method of item analysis and factor analysis, 51 items were selected for the scale of maternal behavior. 2. A factor analysis showed 7 factors(Reasoning guidance, Affect, Antliorian Control, Achievement, Overprotection, Active Involvement, Limit Setting) as separated domains from each others. 3. The reliablity coefficient of the scale was ranged from 62 to 81 sufficient to secure reliability. 4. Percentile ranks were drived from the total score and quartiles were calculted for the each of seven factor's scores. The present study presents a potentially highly useful way of measuring maternal behavior of 4th-6th grade elementary school children in Korea.

  • The purpose of this study was to investigate the difference of visual evaluation about silhouette image. The specific objective were; 1) to construct of silhouette image evaluation instrument using semantic differential scale for the purpose of measuring the width and length; 2) to identify the factor structure of the silhouette; 3) to test the difference of visual perception to the silhouette as the variation of width; 4) to test the difference of visual perception to the silhouette as the variation of length; 5) to test interaction effect between width and length. The major finding were; For the visual evaluation of silhouette as shoulder width variatiorl, there were significant difference in hardness and softness factor. For the hard and soft image, we should express by variation of the shoulder width. For the visual evaluation of silhouette as skirt width variation, there were significant difference in attention factor. For the attensive image, we should express by variation of the skirt width. For the visual evaluation of silhouette as skirt length variation, there were significant difference in activity factor. For the active image, we should express by variation of the skirt length.

  • Clustering for gene expression data without filtering out noise genes may be distorted or derived inappropriate inference. Identifying significant genes and deleting noise before major analysis is necessary fur meaningful discovery from genes expression pattern. We proposed a new method of finding significant genes using factor analysis which is done on transposed data matrix. We construct significance score that is sum of factor loadings for declared significant number of factor, and set threshold through replication. Our proposed method works well for simulated time-course data for finding significant genes even though variance level gets larger.
