Environment-friendly growth enhancers for rice are being promoted to reverse the negative impact of intensive chemical-based and conventional rice farming on yield sustainability and environmental problems. Several rhizosphere microorganisms and pyroligneous acids (PA) had demonstrated beneficial influence on growth, yield and grain quality of rice. Since most of the previous study had evaluated the effect of PGPR and PA on paddy rice singly, the effect of combined application of these on the growth and yield of paddy rice and on some soil chemical properties were determined. A four factorial pot experiment was conducted to evaluate the effect of PGPR, PA in combination with fertilizers and on different soil types. There were 54 treatment combinations including the control with three replications under complete randomized design. Plant growth parameters were evaluated using standard procedures during tillering and heading stages. Rice yield and some soil chemical properties were determined at harvest. Results showed that inoculation of Bacillus licheniformis and Fusarium fujikuroi enhanced plant growth by increasing the plant height which could be ascribe to its ability to promote IAA and GA production in plants. Inoculation of Rhizobium phaseoli enhanced chlorophyll content indicative to its ability to improve the N nutrition. However, these plant growth benefits during the vegetative stage were override by the fertilizer application effect especially during the maturity stage and grain yield. High fertilization rates on coarse-textured soil without nutrient loss resulted to high available nutrients and consequently high yield. Wood vinegar application however improved nutrient availability in soil which could be beneficial for improving soil quality. Further evaluation is necessary to fully assess the potential benefits that could be derived from inoculation of these organisms and wood vinegar application in different soil environment especially under different field conditions.

Purpose: The purpose of this study was to investigate the effects of a profanity intervention application on interpersonal relationship ability, aggression, and empathic ability among female middle school students. Method: The subjects of the present study were freshmen students at a girls' middle school in Gyeonggi-do. The profanity intervention application was implemented from November 20th to 27th, 2017. The pre- and post-tests were conducted one week before and two weeks after the intervention, respectively. The study was designed as a randomized controlled study and the collected data were analyzed using SPSS/WIN 23.0 (Chicago, IL). A homogeneity test between the two groups was performed using $x^2$ test, Fisher's exact test, independent t-test, and ANCOVA. Results: The two groups were found to be homogeneous in the pre-test. After the implementation of the profanity intervention application, aggression significantly decreased (F=20.17, p<.001) and interpersonal reactivity (F=5.92, p=.023) and empathy (F=11.10, p=.003) significantly increased in the experimental group compared to the control group. Among the factors related with aggression, verbal aggression, anger, and hostility significantly decreased in the experimental group. Meanwhile, among the factors of interpersonal reactivity, empathic concern and perspective-taking significantly increased and, among the factors of empathy, cognitive empathy significantly increased in the experimental group compared to the control group. Conclusion: Based on the findings of the present study, various intervention programs that can consistently improve the moral and ethical sensitivity of students should be presented starting from elementary school to prevent verbal violence in adolescents.

In this study, the effect of cooperative computer-assisted instruction upon students' conceptual under-standing,application ability, and learning motivation were investigated by a previous achievement level. The treatment and the control groups (2 classes) were selected from a middle school in Seoul, and taught about the motion of molecule for 5 class periods. Prior to the instructions, a learning motivation test was administered and used as covariate. The scores of a previous achievement test were also used as covariate. The scores of the mid-term science examination were used as blocking variable. After the instructions, the conceptions test, the application test, and the learning motivation test were administered. Two-way ANCOVA results revealed that there were no significant differences in the scores of the con-ceptions test and the application test. However, the scores of the treatment group were found to be significantly higher than those of the control group in the learning motivation test.
