In this experiment, gene actions were analysized for seven barley parents in order to obtain basic information on their genetic improvement by diallel crosses. The results obtained were summarized as follows. In analysis of variance, additive, dominant, maternal and reciprocal effects were observed significantly for culm length, tiller number, number of spiked per plant, culm diameter, awn length, leaf width, number of grains per spike, and 1000 grain weight. Over-dominance was shown by Vr-Wr graphic analysis in five characters such as tiller number, number of spikes per plant, length of flag leaf, number of grains per spike, and 1000 grain weight, and partial dominance in four characters such as culm length, culm diameter, awn length, and leaf width. Component of genetic varience analyzed for four characters such as culm diameter, awn length, length of flag leaf, and leaf width showed that additive effects were higher than dominant effects. Culm length, tiller number, number of spikes per plant, number of grains per spike, and 1000 grain weight showed dominant effects higher than additive effects. The narrow-sense heritability for awn length, leaf width, and number of grains per spike showed high values as more than 0.62, while broad-sense heritability for culm length, number of spikes per plant, culm diameter, awn length, leaf width, number of grains per spike, and 1000 grain weight showed high values as more than 0.65.

Purpose: This study aimed to evaluate the effects of health interventions using virtual reality (VR) on improving knowledge, attitudes, and skills; and inducing behavioral change among adolescents. Methods: This study is a systematic review and meta-analysis following PRISMA guidelines. We searched Cochrane, MEDLINE, Embase, CINAHL, Scopus, Web of Science, and Korean databases between database inception and April 10, 2021. Based on heterogeneity, a random- or fixed-effects model was used, as appropriate, to calculate effect sizes in terms of the standardized mean difference (SMD) and odds ratio (OR). Studies were selected if they verified the effects of health education using VR on adolescents; there was an appropriate control group; and if the effects of education were reported in terms of changes in knowledge, attitudes, skills, or behaviors. Results: This analysis included six studies (n = 1,086). The intervention groups showed greater responses in knowledge and attitudes (SMD = 0.57, 95% confidence interval (CI) [0.12 to 1.02]), skills related to health behavior (SMD = - 0.45, 95% CI [- 0.71 to - 0.19]), and behavioral change after 12 months (OR = 2.36, 95% CI [1.03 to 5.41]). Conclusion: The results confirm the effectiveness of health interventions using virtual reality (VR). Although the analysis include a small number of studies, a case can be made for health interventions using VR to be utilized as educational methods and strategies to prevent risky behaviors among adolescents.

The side effects of drug is closely linked to the people's health and professional. In this case, press report is very important in evaluating the side effects of drug and people's attitude of government's health policy. This study analyzed press report on the side effects of drug based on the main theme, source, responsibility attribution on crisis, frame and network analysis. Theses is a difference of main theme between the press. Daily newspaper focused on the occurrence of crisis and economical newspaper focused on the manufacture company. Professional paper focused on the criticizing of the health policy. The main source of the press on the side effects of drug is the Congressman. There are few articles which mentions about the crisis responsibility. However most articles mentioned that the subject of crisis solutions is the manufacturer. This study found the main meaning by network analysis. This study highlighted the government's crisis management based on the result of content analysis and network analysis.

An analysis of handling performance including the compliance effects is performed. Using the primitive design data of suspension systems, a kinematic model and the three kinds of compliance models are developed. The wheel alignments curves are obtained with the multibody dynamic analysis program ADAMS. The compliance effects of each model are discussed. Since the proposed analysis only requires the raw design data, the better prediction of wheel behaviors is possible in suspension design stage.

Knowledge of the relationship between crop yield and yield-limiting factors is essential for precision farming. However, developing this knowledge is not easy because these yield-limiting factors are interrelated and affect crop yield in different ways. In this study, data for grain yield and yield-limiting factors, including crop chlorophyll content, soil chemical properties, and topography were collected for a small (0.3 ha) rice paddy field in Korea and a large (36 ha) upland corn field in the USA, and relationships were investigated with path analysis. Using this approach, the effects of limiting factors on crop yield could be separated into direct effects and indirect effects acting through other factors. Path analysis provided more insight into these complex relationships than did simple correlation or multiple linear regression analysis. Results of correlation analysis for the rice paddy field showed that EC, Ca, and $SiO_2$ had significant (P<0.1) correlations with rice yield, while pH, Ca, Mg, Na, $SiO_2,\;and\;P_2O_5$ had significant correlations with the SPAD chlorophyll reading. Path analysis provided additional information about the importance and contribution paths of soil variables to rice yield and growth. Ca had the highest direct effect (0.52) and indirect effect via Mg (-0.37) on rice yield. The indirect effect of Mg through Ca (0.51) was higher than the direct effect (-0.38). Path analysis also enabled more appropriate selection of important factors limiting crop yield by considering cause-and-effect relationships among predictor and response variables. For example, although pH showed a positive correlation (r=0.35) with SPAD readings, the correlation was mainly due to the indirect positive effects acting through Mg and $SiO_2$, while pH not only showed negative direct effects, but also negatively impacted indirect effects of other variables on SPAD readings. For the large upland Missouri corn field, two topographic factors, elevation and slope, had significant (P<0.1) direct effects on yield and highly significant (P<0.01) correlations with other limiting factors. Based on the correlation analysis alone, P and K were determined to be nutrients that would increase corn yield for this field. With the help of path analysis, however, increases in Mg could also be expected to increase corn yield in this case. In general, path analysis results were consistent with published optimum ranges of nutrients for rice and com production. We conclude that path analysis can be a useful tool to investigate interrelationships between crop yield and yield limiting factors on a site-specific basis.

This paper deals with a comparison between Taguchi's accumulation analysis method and Nair test on the ordered categorical data from an industrial experiment for quality improvement. a result of Taguchi's accumulation analysis method is shown to have reasonable power for detecting location effects, while Nair test identifies the location and dispersion effects separately, Accordingly, Taguchi's accumulation analysis needs to develop methods for detecting dispersion effects as well as location effects. In addition this paper rewmmends models for analyzing ordered categorical data, for examples, the cumulative legit model, mean response model etc Successively simple, reasonable methods should be introduced more likely to be used by the practitioners.
