The purpose of this study was to investigate the effects of family-of-origin differentiation, ego identity, and attitudes toward children on marital intimacy among married men and women. The participants of this study were 261 married men and 274 married women whose marital period were less than 14 years, and whose first child was less than 12 years old and who were living in Chungbuk Province. Data were analyzed by frequency, percentages, ttest, F-test with Tukey test for post-hoc test, Cronbach ${\alpha}$ for reliability analysis, factor analysis, and Pearson's correlation using the SPSS program(12.0 version). The model test was done with analysis of correlational matrix by the AMOS 5.0 package using a maximum likelihood estimation. Family of origin differentiation, ego identity, and attitude toward children had different effects on marital intimacy according to gender. Also, ego identity was the strongest predictor of men's marital intimacy whereas attitude was the strongest for women's marital intimacy.

Air Quality Index (AQI) is a pointer to broadcast short term air quality. This paper presents one day ahead AQI forecasting on seasonal basis for three major cities in Maharashtra State, India by using Artificial Neural Networks (ANN) and Genetic Programming (GP). The meteorological observations & previous AQI from 2005-2008 are used to predict next day's AQI. It was observed that GP captures the phenomenon better than ANN and could also follow the peak values better than ANN. The overall performance of GP seems better as compared to ANN. Stochastic nature of the input parameters and the possibility of auto-correlation might have introduced time lag and subsequent errors in predictions. Spectral Analysis (SA) was used for characterization of the error introduced. Correlational dependency (serial dependency) was calculated for all 24 models prepared on seasonal basis. Particular lags (k) in all the models were removed by differencing the series, that is converting each i'th element of the series into its difference from the (i-k)"th element. New time series is generated for all seasonal models in synchronization with the original time line & evaluated using ANN and GP. The statistical analysis and comparison of GP and ANN models has been done. We have proposed a promising approach of use of GP coupled with SA for real time prediction of seasonal multicity AQI.

This study identified the present state of store and selection criteria of supplier from the regional fashion buyer point of view and examined the effects of the factors of relative impact between buyer and supplier on the relational bond. The interviews and questionnaires were administered to the owners or the sellers of 85 fashion retail stores in Gwangju. For analysis of data, frequency, means, factor analysis, Cronbach's ${\alpha}$ and regression analysis were applied. The results were as follows. First, in the results of examining the actual conditions of store managers for fashion buyers, fashion buyers complained about lengthy travelling and time consumption inconvenience. They also reported decrease in margin and monthly mean sales over last year. Second, the most important selection the criteria for the supplier were product power, followed by a convenient store layout. Finally, higher quality communication, more compromises, and higher dependence were affected with higher satisfaction, trust, and commitment in suppliers; conversely, the trust and commitment of the buyers decreased relative to the increased power of the suppliers.

Purpose: The purpose of this study was to review and identify factors relevant to workplace bullying in nursing. Methods: Twenty-three studies that met the criteria were selected from a sample of twenty-six studies. These articles were retrieved from a central literature databases (N=13,241). The total correlational effect size (ESr) for each related factor was calculated from Fisher's Zr. A funnel plot inspection (similar to scatter plot) with a trim-and-fill method was used to assess the publication bias of the meta-analyzed studies. Results: From the systematic review, fifty-one factors were identified as having an influencing effect. Fourteen factors (five individual and nine organizational factors) were eligible for meta-analysis. The individual factors included, self-esteem (ESr=-.31), psychological capital (ESr=-.26), and marital status (ESr=-.06) which were significantly correlated with workplace bullying. Organizational factors included, organizational tolerance (ESr=.48), supervisor incivility (ESr=.47), job stress (ESr=.46), group morale (ESr=-.36), group support (ESr=-.35), supervisor leadership (ESr=-.35), group identity (ESr=-.33), and structural empowerment (ESr=-.27). These factors were significantly correlated with workplace bullying. There were no publication biases except for both individual and organizational factors. Conclusion: Organizational factors have more of an greater impact than individual factors on workplace bullying. The results of this study support the need for intervention at the organizational level.
