There are probabilistic forecast models for solar flare occurrence, which can be evaluated by various skill scores (e.g. accuracy, critical success index, heidek skill score, and true skill score). Since these skill scores assume that two types of forecast errors (i.e. false alarm and miss) are equal or constant, which does not take into account different situations of users, they may be unrealistic. In this study, we make an evaluation of a probabilistic flare forecast model [Lee et al., 2012] which use sunspot groups and its area changes as a proxy of flux emergence. We calculate daily solar flare probabilities from 2011 to 2014 using this model. The skill scores are computed through contingency tables as a function of forecast probability, which corresponds to the maximum skill score depending on flare class and type of a skill score. We use a value score with cost/loss ratio, relative importance between the two types of forecast errors. The forecast probability (y) is linearly changed with the cost/loss ratio (x) in the form of y=ax+b: a=0.88; b=0 (C), a=1.2; b=-0.05(M), a=1.29; b=-0.02(X). We find that the forecast model has an effective range of cost/loss ratio for each class flare: 0.536-0.853(C), 0.147-0.334(M), and 0.023-0.072(X). We expect that this study would provide a guideline to determine the probability threshold and the cost/loss ratio for space weather forecast.

In this study, we make an evaluation of a probabilistic flare forecast model (Lee et al. 2012) which use sunspot groups and its area changes as a proxy of flux emergence. We calculate daily solar flare probabilities from 1996 to 2014 using this model. Overall frequencies are 61.08% (C), 22.83% (M), and 5.44% (X). The maximum probabilities computed by the model are 99.9% (C), 89.39% (M), and 25.45% (X), respectively. The skill scores are computed through contingency tables as a function of forecast probability, which corresponds to the maximum skill score depending on flare class and type of a skill score. For the critical success index widely used, the probability threshold values for contingency tables are 25% (C), 20% (M), and 4% (X). We use a value score with cost/loss ratio, relative importance between the two types of forecast errors. We find that the forecast model has an effective range of cost/loss ratio for each class flare: 0.15-0.83(C), 0.11-0.51(M), and 0.04-0.17(X), also depending on a lifetime of satellite. We expect that this study would provide a guideline to determine the probability threshold for space weather forecast.

Objective: The purpose of this study was to apply the Basic CPR(Cardiopulmonary resuscitation) training education program and identify its effects on knowledge of Basic CPR and skills of Basic CPR in second grade high school students. Methods: The training program was conducted for 16 weeks between March 26 and July 9, 2005 using a non-equivalent control group pretest-post test design by dividing 60 students in a half for both the experimental group and the control group. General characteristics, the effect of the education were evaluated with $x^2-test$, t-test, ANCOVA, Repeated Measure ANOVA and Bonferonni with SPSS 11.0/pc. Result: After the CPR education program application, knowledge score in the experimental group increased to 20.57 right after the education from 9.32, the score measured before the training, 19.11 after 8 weeks and 18.29 after 12 weeks. On the contrary, the control group's score showed no significant before the training. According to the result of knowledge score comparison between the experimental and control group at each point in time, the experimental group had a significantly high score in knowledge at every point(p<0.001). In the effect durability for knowledge of the training education program in process time after the training program in the experimental group, the durability of effect was identified despite the elapsing time. Scores of skills for Basic CPR increased from 1.21, the score measured before the training program, to 30.07 right after the education, 23.50 after 8 weeks and 17.57 after 12 weeks in experimental group. On the contrary, the control group showed an immaterial increase. According to the result of skill score comparison between the experimental and control group at each point in time, the experimental group had a significantly high score in skill at every point(p<0.001). The score for skill increased significantly right after the education compared to the score prior to the education. Conclusions: These findings suggest that Basic CPR training education program facilitate knowledge of CPR and skill of CPR in high school students. Therefore, it would be necessary to include the Basic CPR training program in high school education curriculum. However, the effect of Basic CPR knowledge maintains for a few period, and the effect of maintaining the skill is shorter than the maintenance of knowledge so regular reeducation is considered to be needed.

This paper evaluates precipitation forecast skill of Global/Regional Integrated Model system (GRIMs) over South Korea in a boreal winter from December 2013 to February 2014. Three types of precipitation are classified based on development mechanism: 1) convection type (C type), 2) low pressure type (L type), and 3) orographic type (O type), in which their frequencies are 44.4%, 25.0%, and 30.6%, respectively. It appears that the model significantly overestimates precipitation occurrence (0.1 mm d^-1) for all types of winter precipitation. Objective measured skill scores of GRIMs are comparably high for L type and O type. Except for precipitation occurrence, the model shows high predictability for L type precipitation with the most unbiased prediction. It is noted that Equitable Threat Score (ETS) is inappropriate for measuring rare events due to its high dependency on the sample size, as in the case of Critical Success Index as well. The Symmetric Extreme Dependency Score (SEDS) demonstrates less sensitivity on the number of samples. Thus, SEDS is used for the evaluation of prediction skill to supplement the limit of ETS. The evaluation via SEDS shows that the prediction skill score for L type is the highest in the range of 5.0, 10.0 mm d^-1 and the score for O type is the highest in the range of 1.0, 20.0 mm d^-1. C type has the lowest scores in overall range. The difference in precipitation forecast skill by precipitation type can be explained by the spatial distribution and intensity of precipitation in each representative case.
