The purpose of this study is (1) to demonstrate that ignoring group differences may mislead to incorrect conclusion when analyzing correlation data (e.g., factor analysis), (2) to highlight the importance of the data analytic method considering group differences, and (3) to provide ways of incorporating group differences in data analysis. In study, 1, ignoring group difference in factor analysis may mislead to incorrect factor structure. To remedy this, z-transform method and group analysis tool in covariance structure models were suggested. In study 2, the group differences effect was illustrated by using real data (IQ test data).

This study regarded fashion selection criteria as clothing consumption value and desired fashion images, and examined selection differences according to regional subculture groups. Clothing consumption value is a direct value that people seek with clothing products and a perceived value which is divided into emotional, social, price, quality values. Fashion image which is a feeling communicated to others by wearing a certain fashion style is the most superficial value. Multivariate Analysis of Variance (MANOVA) was performed to test the differences between regional subculture groups in clothing consumption values and desired fashion images. We found some differences in clothing consumption value specifically in emotional value and social value. The group differences were remarkably significant in fashion image comparison. 'Kang-nam' group pursued 'lively', 'sophisticated', 'charming', feminine', 'gorgeous' image more than 'Kang-buk' group. While 'Kang-buk' group produced lower scores in ideal fashion images, the group had significant higher seeking in 'sportive' image compared to 'Kangnam' group.

This study analyzed the differences for educational training demographic characteristics and provides basic information for efficient education. The meaningful results of this study were as follows. First for gender, seven-factors except for education satisfaction had significant differences. Second for age, five-factors education performance, education satisfaction, professionalism, diversity, and education had significant difference. Third, for occupation and position, eight-factors had significant differences. We realized that senior staff of Grade 3 or above had the highest level in six-factors education concentration, education performance, education satisfaction, motivation, professionalism and diversity. Finally, for employment period, six factors except for professionalism and motivation had significant differences.

An education program was developed and evaluated to improve college students 'understanding on gender differences in dating relationships. This program was designed based on literature review and a survey of students' preference on subjects concerned with dating and premarital education. The program consisted of three sessions which were ‘Are men & women different\ulcorner’, ‘How are they different\ulcorner’, and ‘How can we cope with the differences\ulcorner’. Questionnaires and pre/post interviews were adopted for evaluation of the program. Participants reported that they were satisfied with the structure of the program as well as the teaching methods and materials. The program was effective in recognizing the existence of gender differences, understanding gender differences, and improving skills to maintain intimacy in dating relationships.

Relations of urban heat island and air pollution are analyzed by using $SO_2$ concentration data (winter season in 1985) from 10 sites of Seoul area and differences of wind speed and air temperature in urban and rural area. Urban heat island is developed when daily mean wind speed at urban site is lower than 1.5m/sec or in the interval of 3.0 $\sim$ 3.5m/sec. When differences between urban and rural air temperature is greater than the overall average of those differences, $SO_2$ concentrations of those above-average differences are 1.3 $\sim$ 1.8 times higher than those of below-average differences. The trends are shown obviously at north-eastern area of Seoul (Gilum Dong, Ssangmun Dong, Myeonmog Dong). When intensity of Urban Heat Island is weak, $SO_2$ concentration was reduced in propotion to a rise of wind speed. But $SO_2$ concentration is on the partial increase in spite of a rise of wind speed when intensity of urban heat island is strong.

The purpose of this study was designed to investigate if self-monitoring variable among various individual trait theories and demographic variable would be variables which can explain about the importance differences of consumer service level of retailing in the garment product. The survey was conducted from Feb, 6 to 16, 2002. For this survey, the 118 data were analysed with spss window 9.0 version and Cronbach's, Factor analysis, one-way ANOVA, Duncan test, Frequency, mean, percentage were applied. The results of this study were as follows; 1. Consumer service was classified in attitude/confidence/expert knowledge of salesperson, product display, product information, product assortment, shopping environment, lighting setup. 2. As a result of analyzing the importance differences per consumer service dimension depending on self-monitoring levels, it was not significant differences. 3. As a result of analyzing the importance differences per consumer service dimension depending on demographic variables, it was not significant differences.

Weighted log rank test is a widely applicable test when one is interested in detecting the differences between two groups. In man clinical trials it is common to see no differences in early experiments and does show significant differences later. We propose new weighted log rank test and illustrate it through an example. We also examine the empirical powers and show that the proposed test is more sensitive to detect late differences.

The purpose of this study was to investigate the gender differences in conversational styles of students. This research based on Quantitative survey and qualitative observation. The quantitative data were collected by questionnaire from 708 respondents who were college students and resided in Sunchon. Statistical methods for the data analysis were frequencies, t-test. The cases of observation were 21. As a result, gender differences were founded in lots of conversational styles. Women showed more tendencies than men In communi-cations to listen, to make relationships, to take care of others, to express intimacy and to make private conversation. Men tended to dominate others, to show off capacities and to make public conversation. This gender differences in conversational styles were related to sex role and major studies. From this results it was proposed that education on gender differences in conversational styles should be developed for students to improve their communication skills and to adapt their changing sex role.

Cases of botched information systems implementation have been surfaced due to poor IS project management and control. One major source of such failures is the perceptual difference between the participants of IS projects who should define potential risk factors well before considered IS projects are launched. Based on risk factors cited from prior works, this paper empirically examines the risk factors associated with IS service project management to analyze perceptual differences between the IS service providers and customers in Korea. Data analyses found significant differences in the area of scheduling/resource, technological newness, communications, and sponsorship/ownership while statistically significant differences were observed in eleven individual factors out of forty six risk factors. Risk factors are also ordered in terms of perceived importance to highlight the critical differences.
