Objectives : The aim of this study was to compare psychosocial characteristics of the functional gastrointestinal disorders FGID group, non-FGID group, and control group and determine factors affecting the QOL of patients with FGID. Methods : 135 patients diagnosed with FGID were selected. 79 adults had no observable symptoms of FGID (control group) and 88 adults showed symptoms of FGID (non-FGID group). Demographic factors were investigated. The Korean-Beck Depression Inventory-II, Korean-Beck Anxiety Inventory, Korean-Childhood Trauma Questionnaire, Multidimensional Scale of Perceived Social Support, Connor-Davidson Resilience Scale, Patient Health Questionnaire-15 and WHO Quality of Life Assessment Instrument Brief Form were used to assess psychosocial factors. A one-way ANOVA was used to compare differences among groups. Pearson correlation test was performed to analyze the correlation of psychosocial factors and QOL of the FGID group. Further, a hierarchical regression analysis was conducted to determine factors affecting the QOL of the FGID group. Results : Between-group differences were not significant in demographic characteristics. Depression (F=48.75, p<0.001), anxiety (F=14.48, p<0.001), somatization (F=24.42, p<0.001) and childhood trauma (F=12.71, p<0.001) were significantly higher in FGID group than in other groups. Social support (F=39.95, p<0.001) and resilience (F=17.51, p<0.001) were significantly lower in FGID group than in other groups. Resilience (β=0.373, p<0.01) was the most important explanatory variable. The explained variance was 47.2%. Conclusions : Significantly more symptoms of depression, anxiety, childhood trauma, and somatization were observed for the FGID group. This group also had less social support, resilience, and quality of life than the non-FGID and control groups. The key factor for quality of life of the FGID group was resilience.

This study examined the organizational status of female employees in three major over-the-air broadcasting companies in South Korea in terms of both formal and informal organizational structures. Quantitative and qualitative analyses were conducted for the data collected through the official statistical documents on Korean broadcasting industries, in-person/telephone interviews, and survey. The results show that the proportion of female employees in the three major over-the-air broadcasting companies remained relatively unchanged at about as low as 10 per cents during the past 10 years, Furthermore, most of them are positioned in the lower hierarchical positions. The informal organizational status of female employees in terms of informal organizational culture, informal network, and mentoring, also reveals inequal conditions in many respects. Concerning role assignments, no significant evidence of sexual discrimination was found. Discrimination against women in assigning core roles such as political and economic news reporting and drama producing, however, was still prevailing. Currently, a marked increase of female proportion is observed among newly hired reporters, producers, and announcers. In the long term, these trends can bring positive changes in the status of female employees in the broadcasting industry organization.

The purpose of this study was to examine the effect of individual tendency of individualismcollectivism and the type of incentive system on pay satisfaction. Data were collected from 243 workers employed in a variety of organizations and a hierarchical regression and MANOVA was conducted to test hypothesis. The results of regression indicated that the interaction between the type of incentive and tendency of collectivism has positive influence on pay satisfaction. In addition, the results of MANOVA indicated that the interaction between individual tendency of individualismcollectivism and the type of incentive system has significant effect on pay satisfaction Specifically, the tendency of individualism has positive influence on the pay satisfaction under the individual incentive condition. However, the tendency of collectivism has negative influence on the pay satisfaction partially under the individual incentive condition. In addition, the tendency of collectivism has positive influence on the pay satisfaction under the group incentive condition. These results suggest that careful consideration in the organization need to decide for the use of individual incentive system, when we regard the Korean culture as high tendency of collectivism. In other words, individual incentive system may could not provide pay satisfaction to the employees who have high level collectivism. However, to generalize these results, more studies were examined in the future.

Two different modelling approaches to dune dynamics have been established thus far; continuous models that emphasize the precise representation of wind field, and feedback-based models that focus on the interactions between dunes, rather than aerodynamics. Though feedback-based models have proven their capability to capture the essence of dune dynamics, the compatibility issues on these models have less been addressed. This research investigated, mostly from the theoretical point of view, the algorithmic compatibility of three feedback-based dune models: sand slab models, Nishimori model, and de Castro model. Major findings are as follows. First, sand slab models and de Castro model are both compatible in terms of flux perspectives, whereas Nishimori model needs a tuning factor. Second, the algorithm of avalanching can be easily implemented via repetitive spatial smoothing, showing high compatibility between models. Finally, the wind shadow rule might not be a necessary component to reproduce dune patterns unlike the interpretation or assumption of previous studies. The wind shadow rule, rather, might be more important in understanding bedform-level interactions. Overall, three models show high compatibility between them, or seem to require relatively small modification, though more thorough investigation is needed.

The purpose of this study was to investigate the influence of stress in families of children with disabilities upon a problem-solving ability based on a buffering effect of family resilience through life cycle. To achieve this purpose, the subjects in this study was 546 parents who have kindergarten, elementary, middle & high school students in special schools. The date for this study were derived from questionaries and the answer sheet was analyzed by SPSS(VER. 14). A descriptive statistics, correlation analysis, hierarchical moderating regression analysis were used to investigate the general information and the difference of perception between groups. The findings of this study were as follows: Higher belief system, higher organization type, higher communication process of the family with disabled children tend to appear more positive influences on buffering effects for stresses of family and solving-problem abilities. Findings from the current study demonstrate that the buffering effect of family resilience indicate to have positive influences on the relationship between the stress and the problem-solving ability in the family with disabled children.

This study was conducted to provide the basic data for improving the working environment and welfare level of the security guard by identifying the primary effects of stress response on fatigue with emotional labor and identifying the adjustment effects with coping strategy. The data were collected from 214 security personnel using questionnaire and the statistical tests of correlation, heavy return analysis and hierarchical return analysis using the SPSS 18.0 statistics program were used to reach the conclusion that: First, it has been shown that the emotional labor of a security guard affects fatigue Second, the effects of emotional labor on fatigue of a security guard have been shown to have the effect of coping strategy. Based on the above studies, it was concluded that the emotional labor of a security guard was affected by fatigue and could be controlled by a stress coping strategy. Therefore, it is believed that there is a need to seek an autonomous corporate culture based on the organization's performance by changing the management system for employees at the organizational level so that security guards can use an active way of coping.

The aim of this study was to provide basic data that could give a positive effect for both new dental hygienists and dental institutions by identifying the impact of one the job training on the organizational socialization, targeting 162 new dental hygienists who currently worked in dental clinic. The data were analyzed using the chi-squire, independent-samples t-test, hierarchical regression analysis. It was shown that the characteristics and contents of a duration of inservice training for new dental hygienists, difficulty, satisfaction, and details of on-the-job training affected organizational socialization by 26.1%. The factor that had the greatest impact on the organizational socialization was dental hygiene service training, followed by guidance of hospital service regulations. This study was significant in that it applied the concept of organizational socialization to the dental hygienists. The future study on the more effective and systematic training program will be needed to help new dental hygienists be socialized more effectively in the new organization.

Numerous studies have reported that genes with similar expression patterns are co-regulated. From gene expression data, we have assumed that genes having similar expression pattern would share similar transcription factor binding sites (TFBSs). These function as the binding regions for transcription factors (TFs) and thereby regulate gene expression. In this context, various analysis tools have been developed. However, they have shortcomings in the combined analysis of expression patterns and significant TFBSs and in the functional analysis of target genes of significantly overrepresented putative regulators. In this study, we present a web-based A Functional Clustering Analysis Tool for Predicted Transcription Regulatory Elements and Gene Ontology Terms (FCAnalyzer). This system integrates microarray clustering data with similar expression patterns, and TFBS data in each cluster. FCAnalyzer is designed to perform two independent clustering procedures. The first process clusters gene expression profiles using the K-means clustering method, and the second process clusters predicted TFBSs in the upstream region of previously clustered genes using the hierarchical biclustering method for simultaneous grouping of genes and samples. This system offers retrieved information for predicted TFBSs in each cluster using $Match^{TM}$ in the TRANSFAC database. We used gene ontology term analysis for functional annotation of genes in the same cluster. We also provide the user with a combinatorial TFBS analysis of TFBS pairs. The enrichment of TFBS analysis and GO term analysis is statistically by the calculation of P values based on Fisher’s exact test, hypergeometric distribution and Bonferroni correction. FCAnalyzer is a web-based, user-friendly functional clustering analysis system that facilitates the transcriptional regulatory analysis of co-expressed genes. This system presents the analyses of clustered genes, significant TFBSs, significantly enriched TFBS combinations, their target genes and TFBS-TF pairs.
