Objectives : The purpose of this study was to test stage model in Traumatic Brain Injury(TBI) patients. According to the stage model, attention deficits which is basic stage in information processing lead to memory disturbance and subsequently affect higher-order cognitive function such as memory, decision-making, abstract thinking, and judgement related to executive function. Therefore, it was hypothesized that attention affect recall(retrieval efficacy) related to executive function mostly relative to other cognitive function, in TBI patients with low executive function. Methods : Participants were referred to a TBI clinic and then was rated on K-WAIS and Executive Intelligence Test(EXIT). Participants were divided into two groups according to Executive IQ(EIQ) score, which of high function group(N=67) was more than 80(above low average) and of low function group(N=52) was under 80 (under borderline). To test the stage model, using hierarchical regression analysis, recall(retrieval efficacy) was regressed on 3 subscales(attention, verbal, visuospatial scale) after controlling for IQ according to each group. Furthermore, the mediation effect of attention between retrieval efficacy and verbal, visuospatial score was analyzed. Results : In the low function group, only attention area predicted significantly recall(retrieval efficacy), indicating that lower attention were related to lower EIQ after controlling for IQ. In the high function group, no area predicted significantly retrieval efficacy. In the low function group, verbal and visuospatial scale did not predicted significantly retrieval efficacy, indicating that there was no evidences supporting the mediation model. Conclusion : Only attention affect retrieval efficacy in TBI patients with low executive function. But, the mediation effect of attention between retrieval efficacy and verbal and visuospatial scale was not tested in the low function group. These results implied that stage model was tested partially. In treating cognitive deficit in TBI patients, it is necessary to develop cognitive rehabilitation program based on stage model. Furthermore, it is necessary to necessary to test mediation model in the future study.

Based on the stimulus-organism-response model, this study investigated the effects of three types of green performance appeals (i.e., before-, after-, and before/after-appeals) on consumer word of mouth (WOM) mediated by anticipatory hope. As the degree of consumer susceptibility to advertising varies by individual, individual perceived consumer effectiveness (PCE) was examined as a moderated mediating variable. A total of 191 responses were analyzed using SPSS 27.0 for analysis of variance and PROCESS procedure. Results showed the mediating role of anticipatory hope between advertising appeals and WOM: participants reported greater anticipatory hope when they viewed the advertisement with after- and before/after-appeals. This mediation was moderated by participants' PCE. The effect of green performance appeals on WOM was mediated by participants' anticipatory hope when their PCE was low; however, when participants' PCE was high, the mediation was not significant. The findings show that advertising appeals highlighting the effectiveness of green performance can attract consumers who do not believe that product consumption affects a sustainable environment and spread WOM. This research provides insights to fashion brands by suggesting effective green advertising strategies that can increase consumers' voluntary information-sharing behavior.

This study explores the effects of technology innovation activity on a profitability and the default risk of firms. Sample for this study consists of manufacturing firms listed on the Korea Stock Exchange from 1st January 2000 to 31st December 2007. We use of R&D ratio as a proxy of technology innovation activity. The default probability proxied for the default risk of firms is measured by the Merton's (1974) model where accounts for a market value of firms and a volatility of it. This study provides evidence that technology innovation activity has a positive effect on a profitability, but a negative effect on the default risk of firms. Our study also finds the significant mediation effect of profitability that the enhancement in profitability resulting from technology innovation activity lowers the default risk of firms.

Recently, knowledge transfer has been recognized as one of the major factors for success of IT projects but little investigated in Information Systems research. IT project, which needs collaboration between organization's IT project team and external partner, is an critical source for a firm to acquire external knowledge and to achieve its competitive advantage. Based on this recognition on knowledge transfer under IT project, we investigate a mediation role of knowledge transfer to IT project performance after identifying its antecedents such as project team capabilities and partner capabilities. The research model is tested by analyzing 161 sample data gathered from firms' employees who have participated IT projects within last two years. The results reveal that knowledge transfer has full-mediation effect between its antecedents and IT project performance. Moreover, project team capabilities have more impacts on knowledge transfer than partner capabilities do.

In this study, we analyzed 82 dust damage dispute mediation cases over the past 5 years and evaluated cases where the probability of damage was verified through dust concentration measurement, modeling prediction, and chemical composition analysis. The cause of dust damage was a construction site, which accounted for most of the damage (97%), and was closely related to the distance from the construction site, total floor area of the construction site, and construction duration. Compensation was decided in only 33% of dust damage cases, and in only 6% (five cases) were damages determined using scientific techniques such as dust measurement, and forecasting. The main criteria for determining compensation were whether administrative measures were taken and evidence of damage in the form of videos and photos. In the future, measuring or model for the amount of dust damage is necessary to determine whether the limit has been exceeded and to revise the standard for calculating compensation through various lines of evidence of dust damage.

Based on the theory of planned behavior, this study aims to examine the structural equation model among consumers' concerns and purchase intentions for alternative meats. Data were collected from 300 adults living in Kyeonggi Province. Results show that animal welfare, environmental concern, and health concern all have a direct and significant effect on purchase intention of alternative meat, and the mediation effect is also significant, indicating a partial mediation effect. The image of a company as caring about animal welfare and contributing to public causes can help sell alternative meats. Media publicity focusing on animal welfare for alternative meats can improve the attitudes of domestic consumers as well as their intention to purchase alternative meat products.

Purpose: This study was conducted to test whether sleep disturbance mediates the effect of pain on fatigue, whether fatigue mediates the effect of pain on depression, and whether fatigue mediates the effect of sleep disturbance on depression. Methods: This study was conducted from September 12th to December 20th, 2011. One hundred eighty-eight breast cancer patients were recruited from D city and S city in Korea. The instruments used in this study were the pain, sleep disturbance, fatigue, and depression scales. Data were analyzed using descriptive statistics, Pearson correlation coefficients, and mediation pathway with the SPSS 12.0 and AMOS 20.0 programs. Results: There was correlation among pain, fatigue, sleep disturbance, and depression. Mediation analyses indicated that pain influences fatigue. sleep disturbance, and depression directly as well as indirectly. Sleep disturbance influences fatigue and depression directly, also fatigue influences depression directly. But sleep disturbance had no direct effect on depression. Conclusion: Significant correlations among the four symptoms supported the existence of the symptom cluster. Effects of pain on fatigue was partially mediated by sleep disturbance, also effects of pain on depression was partially mediated by fatigue. However, the effects of sleep disturbance on depression was fully mediated by fatigue.
