  • This study performed GIS and statistical analyses on the location and spatial characteristics of the slum in Daejeon. Spatial data of 648 slum residents in Daejeon were collected and 131 residents among them were surveyed. The results showed the trends of higher rent, lower social exclusion and closer neighboring relations in slum center than the surrounding areas, which could be interpreted as the interrelated multilateral effects of the micro- (housing), meso- (relations), exo- (community) and macro- (government policy) systems. The strong bonds among neighbors and various supports from social service facilities elevated the slum area's rent and diminished residents' social exclusion more than housing conditions (for instance, poor hygiene and low safety). Slum tenants willingly paid a premium for their substandard housings and refused moving to governmentally provided modern housing units. In urban development, administrative authorities need to be cautious about slum uprooting. Much rather an alternative renewal approach is needed which protects the slum's intimate relations while improving its overall living standards.

  • The purpose of the present study was to investigate the age-related differences in recall and to assess effects of presentation modality, encoding condition and cue modality on recall in terms of encoding specificity principles and dual-coding theory. Eighty children in each of 3grades(first, third and fifth) were presented a 30-item set of pictures or words on cars for recall in a study-test procedure. The experiment was designed as a 3(age) x 2(presentation modality:picture or word) x 2(encoding condition:random or category) x 2(cue modality:picuture or word) factorial design. Statistical analyses were with four-way ANOVA and $Scheff\acute{e}$ test. It was concluded from these results that when the stimulus was presented by pictures, encoded by category and the cues were also presented by pictures, recall increased in all ages. These results were interpreted in terms of encoding specificity principles and dual-coding theory.

  • This study aims to identify the importance and satisfaction levels of home meals of high school students. A developed survey was conducted on July 10 through July 13, 2012. Of 12 high schools located in three different areas in South Korea, three high schools were singled out. For the analyses of the study, the following statistical methods were employed: frequency, cross-tabulation, independent sample t-test, one-way ANOVA, and Duncan as a post-hoc test. As a result, food experiences and education through home meals during childhood promote close ties with other family members and help them develop the food taste and preference that can naturally raise the meal satisfaction level by developing proper eating habit. More implications and discussion are suggested.

  • The purpose of this study was to investigate the effects of consumer's status type (status consistency and status inconsistency) on clothing expenditures. Data were obtained from Urban Household Economy Survey published by the National Statistical Office. Multiple regression analyses of variance and Scheffe tests were4 utilized in this study. The effect of the status inconsistency was categorized by three variables such as education occupation and income levels of households. The overprivileged status group which had higher levels of income than the levels of occupation of education spent most on clothing whereas the underprivileged status group which had higher levels of income than the levels of occupation of education spent least on clothing. This study showed that there were significant differences in clothing expenditures among status groups classified by levels of income and education or by levels of income and occupation. Among status group classified by levels of education and income there was a significant difference in clothing expenditures between overprivileged status group and underprivileged status group. In conclusion income has the strongest effect on the clothing expenditures. The results of study can help to understand consumer buying behavior and also give insights of marketing strategy in the apparel industry.

  • This study examined those problems noticed under the Asymptotically Generalized Least Squares estimator in evaluating a structural model of physical health. The problems were highly correlated parameter estimates and high standard errors of some parameter estimates. Separate analyses of the endogenous part of the model and of the metric of a latent factor revealed a highly skewed and kurtotic measurement indicator as the focal point of the manifested problems. Since the sample sizes are far below that needed to produce adequate AGLS estimates in the given modeling conditions, the adequacy of the Maximum Likelihood estimator is further examined with the robust statistics and the bootstrap method. These methods demonstrated that the ML methods were unbiased and statistical decisions based upon the ML standard errors remained almost the same. Suggestions are made for future studies adopting structural equation modeling technique in terms of selecting of a reference indicator and adopting those statistics corrected for nonormality.

  • This paper is an analysis of the Category Individual Residence urban spatial structure along the National Route BO (Koushu-Kaido), one of the major roads in Japan, and the degree of differences between locations and its changes between the points of time. The analysis was based on the GIS technique. Whilst, previous studies were based on municipal boundaries or mesh units as sources of data, GIS allowed the use of variable geographical units, Roadside zone, Inner zone, North zone, South zone, Blocks. As an example to apply the technology of GIS, 1986's and 1991's building polygon data of the Urban Planning Bureau of Tokyo Metropolitan Government are used. The layers referred to the analyses is the building polygons with the amount of stories, building area, floor area and the material of the building. Two statistical analysis are executed; one is the test of the regional equality about the number of story of building, building area, floor area and fireproof building ratio.

  • Simplified mathematical formulas are presented to predict deformations during the plate forming process when the heating parameters are given. To obtain the formulas, firstly, the thermal analysis for steel plate is performed, and the thermo-mechanical analysis is followed with actual heating conditions. The analyses have been carried out by the commercial software MARC, which is programmed based on the FEM. Secondary, the results of the mechanical analysis are synthesized with their variables for a statistical approach, which results in simplified formulas. The results of the analysis are well compared with those of experimental measurements.

  • The purpose of this study was to investigate the effects of store image preferences on clothing impulse purchasing of male college students. The sample included 290 male college students, and an instrument was developed based on the previous studies. The statistical analyses used for this study were factor analysis and multiple regression. The result of factor analysis showed that store image preferences consisted of five factors : promotion, display, service, product, brand preferences. Clothing impulse purchasing consisted of product-driven impulse purchasing, situation-driven impulse purchasing, emotion-driven impulse purchasing. Multiple regression revealed that there were significant effects of store image preferences on dimensions of clothing impulse purchasing. For example, promotion preference factor had a positive impact on product-driven impulse purchasing and situation-driven impulse purchasing, but had a negative impact on emotion-driven impulse purchasing. The relative importance of store image preference factors were different according to different dimensions of clothing impulse purchasing.

  • It has been regarded as important in both academic and practical issues how to evaluate service quality. In addition international traveling will be growing due to increasing income and globalization. Thus, it is very important to measure the international airport's service quality properly. This study was conducted to identify the service quality factors which are utilized to measure international airport's service quality. According to the statistical analyses' results of this study, seven service quality factors and thirty two measurement items were found to evaluate international airport's service quality. They are some different from those which PZB(1988b) identified to measure service quality. This result implies that it is necessary to find the service quality factors reflecting the unique characters of the service organization when measuring service quality of a service organization.

  • An internet addiction measure(Park et al., 2001) and an asocial behavior measure(K. J. Lee, 1997) were administered to 232 6th-grade students. Statistical analyses were by mean-difference scores and t-test. Results showed that all aspects of internet addiction(preoccupation, compulsive use, relapse, tolerance/dependence and impediments in daily life) were related to both the inner asocial behaviors of depression, social withdrawal and over-anxiety and the external asocial behaviors of aggressiveness, delinquency and hyperactivity. The only exception was that tolerance/dependence was not related to delinquency. Boys addicted to the internet were more socially withdrawn, aggressive, delinquent and hyperactive than girls. From the results, it can be suggested that internet education should be carried out from the elementary educational level.
