Recent public information project, which has been organized mainly to large companies is a situation that is being reorganized to small and medium-sized systems integration company. However, many of the small and medium-sized companies lack knowledge of the systematic risk management. Thus, in connection with the revenue, it involves a number of problems. Therefore, in this paper, we present a risk element that occurs mainly in the field of the project, providing a model for measuring the risk element by risk level costs associated with this. Through the convergence, we aim at providing a management system that is able to make the project successfully accomplished, predicting the risk that occurs in advance to pursue the project; Based on the proposed model, it is possible to secure a proper size of reserve fund so it is expected to enable companies to ensure the cost of risk analysis.

Touch input method is unintended difficulties regarding touch and input have increased with touch input methods when compared to using a mouse for input in previously existing menus. This study attempted to analyze usability evaluations according to form and size changes of minimal button forms in button menus. This attempted to verify possibilities through more effective applications of the quantitative performance prediction evaluation model through comparative analysis of Fitts' Law, the representative model of the regression model formula and the interface human performance evaluation method, so that applications can be made in interface designs of touch input methods. Therefore it was significant in that it made reflections on design with consideration given to use user times according to button forms and size changes that can be applied to touch screens.

This study aims to get more accurate and objective result by quantifying the result for the sperm changes through the quantitative analysis by the image processing based on the image obtained microscopically for the testicle cell and sperm change appeared with the passage of time when the radiation is irradiated to the white rat testicle. This study has targeted the white rat of 8 weeks lifespan, the X-ray of 6 MV with 1 time of 2 Gy has been irradiated to the whole body. The testicles of 5 rats at each test group immediately after irradiation, after 2 hours of irradiation, 4 hours, 8 hours and 24 hours has been respectively extracted targeting all 30 white rats of normal control group not irradiated by the radiation and the test group. The state of testicle cell and sperm has been observed in the normal control group and the test group by implementing Periodic acid Schiff dyeing after extraction. 24 hours after irradiation, a gradual decrease in sperm count and testicular cells qualitatively and quantitatively that were identified as significant.

This study was conducted to develop and test the effects of an emotional intelligence program for new nurses. The study design was a mixed method research. Participants were 29(intervention group: 15, control group: 14) new nurse. The emotional intelligence improvement program was conducted once a week for a total of 8 weeks (20 hours).The emotional intelligence program was provided for 8 weeks (20 hours). Quantitative data were analyzed using Chi-square, Fisher's exact test, t-test, repeated measure ANOVA with SPSS/WIN 18.0. Qualitative data were analyzed using content analysis. Quantitative results showed that emotional intelligence, Job stress were no significantly better in the experimental group compared to the control group. According to the qualitative results, the new nurse experienced improvement in emotional intelligence, empowerment, a reduction in stress, Changed from 'alone' to 'us', and as well as I dream of my future self after participation in the emotional intelligence program. A study to apply the emotional intelligence improvement program to nurses at various times and to verify its effectivene.

This study analyzed whether the poverty level among Asian countries has converged, by using data for the 'globalization period'. In particular, we analyzed the impact of trade on convergence by quantitative analysis using two indices; the head count ratio (H) and the human development index (HDI). The σ-convergence measurement and β-convergence measurement method, commonly used in the field of economic growth, are used for the analysis method. Results show that poverty rates have declined on average during the analysis period and there has been an increase in HDI. It seems that there has been improvement regarding poverty. However, this trend is only an indication of the average trend of Asian countries as a whole. As for the convergence between countries, which is the focus of this study, the HDI index shows the converges among countries while the H index does not show significant convergence among countries. It is also difficult to determine that trade has a statistically significant impact on the poverty rate convergence. However, in the case of HDI convergence, trade has contributed to increasing the convergence rates. This results might show that globalization does not guarantee the convergence among countries, and thus, we need to have additional policy in order to reduce the poverty.

In these days, as cyberspace has been recognized as the fifth battlefield area following the land, sea, air, and space, attention has been focused on activities that view cyberspace as an operational and mission domain in earnest. Also, in the 21st century, cyber operations based on cyberspace are being developed as a 4th generation warfare method. In such an environment, the success of the operation is determined by the commander's decision. Therefore, in order to increase the rationality and objectivity of such decision-making, it is necessary to systematically establish and select a course of action (COA). In this study, COA is established by using the method of classifying operational elements necessary for cyber operation, and it is intended to suggest a direction for quantitative evaluation of COA. To this end, we propose a method of composing the COES (Cyber Operational Elements Set), which becomes the COA of operation, and classifying the cyber operational elements identified in the target development process based on the 5W1H Method. In addition, by applying the proposed classification method to the cyber operation elements used in the STUXNET attack case, the COES is formed to establish the attack COAs. Finally, after prioritizing the established COA, quantitative evaluation of the policy was performed to select the optimal COA.
