  • State Highway Agencies (SHAs) have started utilizing cost-plus-time bidding (A+B bidding) since Federal Highway Agency (FHWA) declared it operational on May 4, 1995. Although this technique has successfully accelerated many projects by incorporating construction time in the bidding competition, a framework to illustrate the interactions of incentive/disincentive (I/D) rates on the competitiveness of contractors participating in the bid competition is yet to be developed. In a previous research, authors indicated that for each bid competition there is an efficient cap for I/D rates which are dictated by the capabilities of contractors in project acceleration. However, the results of previous study were based on the assumption that there is a statistically significant relationship between cost and time. In this study, the entire cost-plus-time projects implemented by the Oklahoma Department of Transportation (ODOT) were investigated. Then the significance of relationship between cost and time were analyzed for each contractor utilizing Analysis of Variance (ANOVA) technique, and the price-time function of each contractor was determined by regression analysis. The results of the analysis indicate that there is a significant relationship between cost and time for the majority of contractors. However, a quadratic relationship is not always significant and for some contractors a linear price-time relationship is significant. The results of this project can be used not only by ODOT to optimize the incentive/disincentive rates but also by contractors to determine the most competitive strategies of other bid participants.

  • This study assumed the competitive structure based on genre classification for Korean online game contents market, and carried out the analysis on the degree and characteristics of the competition that appear differently in each sub market classified according to the genre. First, to analyze the market power of the rank 1 and 2 game contents in each genre, using the play time share ratio and standard deviation statistics values in the genre, ANOVA analysis and Cluster analysis were carried out for each genre. According to ANOVA analysis result, in the rank 1 game share ratio in each genre, there was a relationship of 'FPS/Racing > RST/Sports > Poker > Go-stop > RPG > Arcade > Board', and in the play time total share ratio of rank 1 and 2 games, the relationship of 'RTS > FPS/Racing > Sports > RPG > Go-stop > Poker > Arcade > Board' was verified. And in Cluster analysis, the groups of the genres with the degree of market power tendency and the variability at similar level were classified and stated.

  • The purpose of this study was to examine the relationship between perceived stress, college life adjustment, and interpersonal relationship ability in nursing college students and investigate whether or not interpersonal relationship ability mediate the relationship between perceived stress and college life adjustment. Data were collected from 281 nursing students in B city and analyzed by t-test, ANOVA, Pearson correlation coefficient, multiple regression, and sobel test using SPSS/WIN 23.0. The degree of college life adjustment in nursing students was 3.38±0.58. There was negative correlation between college life adjustment and perceived stress(r=-.478, p<.001), positive correlation between college life adaptation and interpersonal relationship ability(r=.617, p<.001). The interpersonal relationship ability had partial mediating(β=.629, p<.001) effect between perceived stress and college life adjustment among nursing students. Therefore, in order to promote college life adjustment of nursing students, and decrease perceived stress, it is necessary to development education and program that to improve interpersonal relationship ability.

  • The purpose of this study was to examine the effects of consumer-brand relationship on purchasing attitudes toward counterfeits. 341 female college students who had purchased fashion luxury brand products were surveyed. For data analysis, descriptive statistics, factor analysis, pearson's correlations, ANOVA, and multiple regression were used. As the results, consumer-brand relationship was classified into three factors; commitment relationship, trust relationship, and emotion relationship. Also, higher consumer-brand relationship was correlated with higher preference and satisfaction, and lower purchasing attitudes toward counterfeits. Also, among the three groups(heavy/middle/low) of consumer-brand relationship, the heavy group had higher preference and satisfaction, and lower purchasing attitudes toward counterfeits. Also, results revealed that 'commitment relationship' and 'emotional relationship' accounted for 32% of the explained variance in 'favorableness', while 'trust relationship' and 'emotional relationship' accounted for 26% and 29% of the explained variance in 'trust toward product quality'. Based on these results, fashion luxury brand marketing strategy would be suggested.

  • This study discusses the meanings of nationality in information behaviour. In this study nationality was represented by citizenship and group personality(here, dependency) Surveys were conducted for data collection, and a questionnaire were completed by 331 participants(158 Korean students and 183 Japanese students). Simple frequency tests and chi-square tests were conducted to examine the proposed relation between citizenship and information behavior, that between dependency and information behavior. Also conducted was two-way ANOVA test to examine the relative significance of two independent variables(citizenship and dependency) in information behavior. The results of chi-square tests showed that both variables have statistically significant relationship with information behavior although the relationship was partially significant. And the results of ANOVA test showed that between the two variables, citizenship was more significant than dependency.
