Objectives: This study aimed to examine the general tendencies of women's divorce intention and to analyze the related variables that affect women's divorce intention. It would help explore the conditions for prevention or intervention of divorce. Methods: For this purpose, the structured survey was conducted by 521 married women aged between 20 and 70 living in Jeollanam-do and Gwangju. The data was analysed by SPSS 21.0 program. Results: First, the average score of divorce intention was 2.04, which was lower than the middle. The average score of self-differentiation, marital communication efficiency, reasonable coping, and social support were a bit higher than the median score. Second, the differences in the divorce intention according to the academic background and household income were statistically significant. Third, marital communication efficiency had the biggest effect on divorce intention and it was followed by avoidance-oriented behavior, reasonable coping, support from the local community, self-differentiation, and household income. Conclusion: It is very important to understand the various factors related to divorce intention especially in individual, marital, social aspects. In addition, it is actually required to develop the couple programs about coping strategies, effective couple communication and problem-solving methods. It also have to imply the requirements considering psychological, social aspects such as self-differentiation and social support.

This study examined the mediating effects of couple communication on self-differentiation and marital satisfaction among married women. The ANOVA, correlation and the multiple regression analysis were used to figure out the relationships and the mediating effects of those variables. The results revealed that self-differentiation was significantly related to marital satisfaction. Also, couple communication was revealed to be a partial and full mediator between self-differentiation and marital satisfaction. The results were as follows. First, there were differences in couple communication and marital satisfaction. Marital satisfaction showed differences according to socio-economic variables such as educational level, occupation, family income, and the years of married life. Educational level and family income made differences in couple's communication. However, socio-economic variables did not make any difference with regard to self-differentiation. Second, there was a significant correlation among all sub-factors for self-differentiation, whole self-differentiation, married couples' communication, and marital satisfaction. Third, the result shows that the mediating effect of couple communication between self-differentiation and marital satisfaction. Couple communication completely mediated the relationship between cognitive vs. emotional function, family projection, emotional cutoff, and marital satisfaction. It also partially mediated the relationship between family regression and marital satisfaction. In addition, there was a tendency to partially mediate the relationship between general self-differentiation and marital satisfaction. The results suggested that self-differentiation and couples communication should be considered together when explaining marital satisfaction among married women. Also, the results implied the importance of the increased self-differentiation and the better couple communication in women's marital satisfaction. Finally, this research suggested the necessity of counseling services to enhance the self-differentiation as well as couple communication programs for the marital satisfaction of women.

Embryonic stem cells can be differentiated into various types of cells, requiring a tight regulation of transcription. Biomarkers related to each lineage of cells are used to guide the differentiation into neural or any other fates. In previous experiments, we reported the guided differentiation (GD)-specific genes by comparing profiles of random differentiation (RD). Interestingly 68% of differentially expressed genes in GD overlap with that of RD, which makes it difficult for us to separate the lineages by examining several markers. In this paper, we design a prediction model to identify the differentiation into neural fates from any other lineage. From the profiles of 11,376 genes, 203 differentially expressed genes between neural and random differentiation were selected by random variance T-test with 95% confidence and 5% false discovery rate. Based on support vector machine algorithm, we could select 79 marker genes from the 203 informative genes to construct the optimal prediction model. Here we propose a prediction model for the prediction of neural fates from random differentiation which is constructed with a perfect accuracy.

This paper intends to increase the performance of export support programs for small-to-medium sized firms promoted by Korea government. A research construct is suggested for effective government support program targeted on the global marketing capability. The data is collected from the firms received the support more than once by Korean governments. The results are shown as follows. First, it is found that those firms who have high propensity to be involved in export business have shown high performance. Second, the firms with high global marketing capability have shown good performance. To be more specific, organizational commitment, strategic initiative, business differentiation, and market knowledge for target markets are found to be critical factors in successful export support program. The business differentiation strategy in target market is very critical. Finally, the degree of program management effectiveness is found to be important in high performance firms. It means that for those firms, much more advanced programs need to be developed. The government should develop diversified programs by considering the degree of global marketing capability.

The current study was conducted to investigate effects of sera taken from Hanwoo at different age on adipocyte differentiation. Sera were taken from Korean native (Hanwoo) steers at 6, 12, 18, and 24 months of age, respectively and supplemented to 3T3-L1 preadipocytes after the cells reached confluence and maintained 10 days thereafter. For the first 2 days (48 h), cells were induced to differentiate by addition of differentiation factors, methylisobutylxanthine, daxamethasone, and insulin. After the differentiation, the cells were incubated without differentiation factors except insulin. The cells lost their fibroblastic shape and showed round-up appearances after 10 days incubation with FBS and the sera of Hanwoo steers. Big lipid droplets appeared in the cells cultured with FBS and the sera taken from Hanwoo at 18 and 24 months of age. After 18 months of age, GPDH activity was statistically higher than 6 and/or 12 months of age (P < 0.05). Based on morphology and Sn-glycerol-3-phosphate dehydrogenase activities, Hanwoo steers expressed aged-dependent adipogenic activities, indicating that aged sera may result in high adipocyte differentiation. It is concluded that the 18 months of age may be 'threshold' to express major adipogenic activities. This may strongly support previous field studies reporting considerable increase in fat contents of Hanwoo carcass at over 18 months of age.

Recently, a lot of companies intend to make spin-offs as the Internet usage is proliferating in the business area. A spin-off means a small but autonomous company which is thought to show higher profitability rather than it stays under the influence of a mother enterprise. To prove our hypotheses, we collected questionnaire data from 104 companies considering spin-offs. From experiments with Factor Analysis, we found that there exist four factors which decision-makers should consider before deciding spin-offs such as competence of unit, competence of mother company, competence of spin-off company, and support of mother company. After massive experiments with Regression Analysis we also found that there are significant three performance factors such as competence of unit, competence of spin-off company, and support of mother company. The survey also asked about three potential strategies that they may have been following for achieving business objectives: Cost leadership, Focus, and Differentiation, Six benefits factors emerged from this study: External competitiveness, Internal competency, Productivity, Change, Cost saving, and Improvement. External competitiveness was the most important benefit, and it predicted a Differentiation and Focus strategy. Productivity and Improvement also predicted a Differentiation strategy. External competitiveness, Change, and Cost saving predicted a Cost leadership strategy. However, organizations followed Differentiation and Focus strategies significantly more than Cost leadership. The assessment thus sheds light on the link between information strategy and spin off. We hope that based on our results, many companies considering a spin-off can make a right decision and expect higher performance in a turbulent business environment.
