and to generate the simulated risk scores. The resulting regression equation was validated by comparing the simulated disease severities with another set of ground- truth data collected in 2015 in multiple kiwifruit orchards. Weather data from the nearest KMA weather stations were used to simulate the Pss-KBB Risk Model. Integrated modeling approach. Daily maximum and minimum temperature and...

increasing variation in climatic conditions under climate change directly influences plant-microbe interactions. To account for as many variables as possible that may play critical roles in such interactions, the use of an integrated modeling approach is necessary. Here, we report for the first time a local impact assessment and adaptation study of future epidemics of kiwifruit bacterial blossom blight (KBB) in Jeonnam province, Korea, using an integrated modeling approach. This study included a...

A logistic model for describing combined effects of both temperature and wetness period on appressorium formation was developed using laboratory data on percent appressorium formation of Colletotrichum acutatum. In addition, the possible use of the logistic model for forecasting infection risks was also evaluated as compared with a first-order linear model. A simplified equilibrium model for enzymatic reactions was applied to obtain a temperature function for asymptote parameter (A) of logistic...

mediocre fit for GFI and RMSEA. As the emotionality of child self-regulation had the lowest standardized regression weight, the variable was removed (as per Fornell & Larcker, 1981). Following this, we redid the CFA, and the second results showed an improved model fit: χ 2 = 198.63, p = 0.000; GFI = 0.92; TLI = ..PAGE:12 Seonhyung Choi & Sunhee Kim 12 0.95; CFI = 0.96; RMSEA = 0.07.

or unfriendly. This study used structural equation modeling to examine the contributions of mother’s coaching competence, parenting behavior, and child self-regulation to peer initiative. Participants comprised mothers of children aged 3 to 5 years (n = 343) in Korea and their teachers (n = 39). Structural equation modeling indicated that the relationship between mothers’ coaching competence and friendly peer initiative was fully mediated by maternal affection and child self-regulation....

a minimum sample size requirement for the three-level quadratic cross-classified multiple membership growth curve modeling, this study employed a simulation under a variety of conditions including the number of measurement occasions (4, 5, and 6), the number of groups (30, 50, 100, and 200), average group size (10, 30, and 50), and multiple membership rates (20% and 40%). Across all of the simulated conditions, no substantial bias was found for the fixed effect and level-one variance component...

mode estimates of the between-school variances in the intercept and slope were substantially overestimated. In general, with the inverse Wishart prior, the Markov chain Monte Carlo (MCMC) posterior median is recommended for cross-classified multiple membership growth curve modeling, except under certain conditions. With the uniform prior, the MCMC mode is recommended for estimating cross-classified multiple membership growth curve modeling rather than the MCMC posterior mean or posterior median.

pork. The calculated thawing rate from the results depending on the high pressure showed the strong trend of increased thawing rate under pressurized condition(P<0.05). And then, the numerical modeling was executed to predict the thawing rate influenced by the pressure level using exponential regression, LnY=0.70623 + 0.00433 ·P (R2=0.9985 ), and it was fairly fit for the functional relation between the thawing rate(Y) and pressure(P) with comparatively high coefficient, R2 of determination.
