Purpose: The purpose of this study was to identify the influence of hope, core beliefs, and social support on the posttraumatic growth of mothers with chronically ill children. Methods: In this study, 94 mothers who gave written consent completed the questionnaires between July 21 and July 31, 2012 when they visited a university hospital in Seoul, Korea. Data were analyzed using t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. Results: Hope, core belief and social support had positive correlations with posttraumatic growth. Models including these variables explained 64.8% (F=55.276, p<.001) of the variance for posttraumatic growth. Hope (${\beta}$=.441, p<.001) was the most influential factor. Conclusion: The findings demonstrate that it is essential for nurses to mediate and facilitate posttraumatic growth of mothers caring for chronically ill children. Furthermore, there is an need to develop and implement new strategies in clinical practice that will result in improvements in posttraumatic growth.

The Korean government has been focusing on supporting technology startups to solve social and economic problems such as low growth, declining economic growth rate, rising youth unemployment rate and lack of new growth engine. Although the failure rate of young technology startups is very high, relevant researches are still scant. On the basis of previous researches, this study has identified four growth factors of technology startups: characteristics of entrepreneurs, technical superiority and originality of business items, focused marketing strategy, and follow-up government support projects. Five young technology startup cases were selected and analyzed in the cosmetics industry which were supported by the Six-month Challenge Platform project of Chungbuk Creation Economic Innovation Center. The main findings of the case study were as follows: First, product development through inhouse R&D rather than external contracted R&D was beneficial to acquiring follow-up government support projects and external investment. Second, choosing a small niche market and concentrating marketing efforts on the target market had a positive effect on firm performance. And, third, relevance of entrepreneurs' college major and technological originality of business items were confirmed to influence firm performance positively in the early stage. The results are expected to help young technology startups survive successfully and establish a foothold for growth in their early stage.

Devising an efficient one-pass frequent pattern mining algorithm has been an issue in data mining research in recent past. Pattern growth algorithms like FP-Growth which are found more efficient than candidate generation and test algorithms still require two database scans. Moreover, FP-growth approach requires rebuilding the base-tree while mining with different support counts. In this paper we propose an item-based tree, called I-Tree that not only efficiently mines frequent patterns with single database scan but also provides multiple mining scopes with multiple support thresholds. The 'build-once-mine-many' property of I-Tree allows it to construct the tree only once and perform mining operation several times with the variation of support count values.

Objective : Present study was carried out to investigate the effect of Gyungohkgo-gamibang extract on hair growth and protein expression in an alopecia model of C57BL/6 mice. Methods : Mice were divided into 3 experimental groups including normal (vehicle), Gyungohkgo-gamibang extract (YNS-10) and 5% minoxidil-treated group. The test materials were daily applied with 0.1 ml per mouse on shaved dorsal skin for 3 weeks. The hair growth was monitored by photograph at 5, 10, 15, 21 days after topical application. Then the changes of hair density and hair thickness in the hair-removed area were evaluated by phototrichogram using folliscope. Also the expression level of growth factors related to hair growth was measured by western blotting. Results : Application of minoxidil or YNS-10 stimulated the hair growth compared to vehicle treatment. Therefore hair density of minoxidil or YNS-10 application was increased about 200% and 210% more than in vehicle application on 14 day, respectively. And hair thickness of both minoxidil group and YNS-10 group was increased about 220% and 210 % more than in vehicle spreading on 14 day, respectively. Futhermore the protein expression of IGF-1 and VEGF were significantly up-regulated on 7 day in YNS-10 and minoxidil-spreaded group compared to vehicle-applied group. Conclusion : These data suggest that YNS-10 has potent stimulating activity on hair growth in C57BL/6 mice and potential usefulness as ingredients of hair tonic and hairrestore.

As the competitiveness of SMEs (small and medium enterprises) is getting more and more improved and globalized, the government provides various consulting services to secure the competitiveness of small and medium firms and support stable growth. However, the assessment of the result from the government's support is generally focused on non-financial factors, such as customer satisfaction and analysis of improvement effect. This paper is in regards to the statistical analysis of how much the government's support in the form of providing consulting services contributes to financial outcomes in terms of profitability and growth. ROA (return on asset) and ROS (return on sales), which are investment profitability and sales profitability respectively, are chosen as an indicator of profitability. For analysis of growth, sales revenue and total asset growth are used. The samples are 44 corporations which are supported by government, and 150 corporations which are selected for comparison, with corporate growth support center program by the Ministry of Trade, Industry, and Energy chosen as the consulting model. After gathering the yearly balance sheets and income statements of the samples from CRETOP, Korea Enterprise Data, the analysis is conducted in the way of identifying the statistical significance of financial difference in the same period between corporates taking consulting services and corporates which have not, and the difference of financial outcomes from the corporates taking consulting services before and after consulting services. As a result, in terms of business growth, it is turned out to have positive difference both in growth ratio and profitability compared to the compared corporations at the significant level. Therefore, it is obvious that the consulting program which government provides to SMEs have direct influence practically to the corporates' management performance.

Today, online education is becoming more important. The effectiveness of online education has been measured by student satisfaction and the possibility of substituting offline education. This study proposes a plan to increase the effectiveness of education in a new form by using online information. Education is the process of socializing and growing learners. Representative negative emotions experienced by learners are stress, anxiety, and depression (SAD). A reduction in SAD will promote student growth and improve educational outcomes. This paper considers online information by dividing it into online educational information support (OEDIS) and online emotional information support (OEMIS). We demonstrate that OEDIS reduces SAD, and OEMIS reduces stress and anxiety. By providing online information, negative emotions can be reduced, and educational outcomes can be improved. This study suggests a new role for online information support, such as emotional change in individuals and solving psychological problems. Online information support goes beyond knowledge transfer and can be used in various fields, such as online education that promotes human growth and positive change, and even healthcare.

Purpose: In Korea, win-win growth policy has been successfully implemented in supply chain and logistics management. In the policy, it is recommended to support supply chain partners with various mechanisms including financial and technical aids. This study attempts to scientifically analyze the effects of direct and indirect win-win growth policy factors on supply chain and logistics management performance through partnership factors. Research design, data and methodology: This study builds a structural equation model reflecting the relationship between the win-win growth policy, partnership and performance factors. The proposed model is verified with the PLS (Partial Least Squares regression) methodology. Data from shipper and logistics companies were collected and analyzed by the PLS model. Results: The analysis showed that both direct and indirect policy factors are meaningful to improve supply chain and logistics performance. Indirect support factors including R&D, management innovation, human resources development and educational supports have positive impacts on partnership factors. Direct support factors including financial aids and fairness also have positive impacts on the performance. Conclusions: This study is meaningful in that it suggests a turning point in which supply chain Win-win growth and partnership efforts are perceived as new value-creating mechanism rather than unilateral cost reduction for logistics industry.
