Background: The commercially available Newcastle disease (ND) vaccines were developed based on Newcastle disease virus (NDV) isolates genetically divergent from field strains that can only prevent clinical disease, not shedding of virulent heterologous virus, highlighting the need to develop genotype-matched vaccines Objectives: This study examined the efficacy of the NDV genotype-matched vaccine, mIBS025 strain formulated in standard vaccine stabilizer, and in carboxymethyl sago starch-acid hydrogel (CMSS-AH) following vaccination via an eye drop (ED) and drinking water (DW). Methods: A challenge virus was prepared from a recent NDV isolated from ND vaccinated flock. Groups of specific-pathogen-free chickens were vaccinated with mIBS025 vaccine strain prepared in a standard vaccine stabilizer and CMSS-AH via ED and DW and then challenged with the UPM/NDV/IBS362/2016 strain. Results: Chickens vaccinated with CMSS-AH mIBS025 ED (group 2) developed the earliest and highest Hemagglutination Inhibition (HI) NDV antibody titer (8log₂) followed by standard mIBS025 ED (group 3) (7log₂) both conferred complete protection and drastically reduced virus shedding. By contrast, chickens vaccinated with standard mIBS025 DW (group 5) and CMSS-AH mIBS025 DW (group 4) developed low HI NDV antibody titers of 4log₂ and 3log₂, respectively, which correspondingly conferred only 50% and 60% protection and continuously shed the virulent virus via the oropharyngeal and cloacal routes until the end of the study at 14 dpc. Conclusions: The efficacy of mIBS025 vaccines prepared in a standard vaccine stabilizer or CMSS-AH was affected by the vaccination routes. The groups vaccinated via ED had better protective immunity than those vaccinated via DW.

Turfgrass, the most widely grown ornamental crop, is severely affected by fungal pathogens including Sclerotinia homoeocarpa, Rhizoctonia solani, and Magnaporthe poae. At present, turfgrass fungal disease management predominantly relies on synthetic fungicide treatments. However, the extensive application of fungicides to the soil increases residual detection frequency, raising concerns for the environment and human health. The bacterial volatile compound, 2,3-butanediol (BDO), was found to induce plant resistance. In this study, we evaluated the disease control efficacy of a combination of stereoisomers of 2,3-BDO and commercial fungicides against turfgrass fungal diseases in both growth room and fields. In the growth room experiment, the combination of 0.9% 2R,3R-BDO (levo) soluble liquid (SL) formulation and 9% 2R,3S-BDO (meso) SL with half concentration of fungicides significantly increased the disease control efficacy against dollar spot and summer patch disease when compared to the half concentration of fungicide alone. In field experiments, the disease control efficiency of levo 0.9% and meso 9% SL, in combination with a fungicide, was confirmed against dollar spot and large patch disease. Additionally, the induction of defense-related genes involved in the salicylic acid and jasmonic acid/ethylene signaling pathways and reactive oxygen species detoxification-related genes under Clarireedia sp. infection was confirmed with levo 0.9% and meso 9% SL treatment in creeping bentgrass. Our findings suggest that 2,3-BDO isomer formulations can be combined with chemical fungicides as a new integrated tool to control Clarireedia sp. infection in turfgrass, thereby reducing the use of chemical fungicides.

This study is intended to present effective career guidance and direction by identifying the various factors involved in the career preparation behavior for the improvement of the employment rate of culinary and foodservice management major field students. This study was established on the hypothesis of a structural relationship that career decision-making self-efficacy develops career maturity and career preparation behavior on the basis of social cognitive career theory, which was verified through empirical analysis. Out of 450 survey responses from by Culinary and Foodservice Management Major Students, a total of 302 questionnaires were used for the final analysis due to missing values and biased responses(response rate: 83.6%). Collected data were identified using SPSS 16.0 and AMOS 5.0. A higher-order factor model was employed (High-order model) before a confirmatory factor analysis, and this study examined its reliability and validity analysis for hypothesis testing. Career decision-making self-efficacy had positive effects on career maturity(t=6.86, p<0.001) and career preparation behavior(t=3.83, p<0.001), and career maturity had positive effects on career preparation behavior (t=2.79, p<0.01). As a result, all hypotheses were accepted. These results confirmed that strengthening students' faith in themselves with competencies is core competencies with career-related issue can be the driving force that can enable students to develop into mature professionals. Therefore, this study suggests an awareness of the importance of career decision-making self efficacy and proposes a need for a systematic and integrated career counseling program that can improve it.

This study examined the factors influencing the relationship between anger and happiness of university nursing students so that they can improve their happiness and perform their studies with better internalized values. The general characteristics, academic efficacy, self-directedness, self-resilience, anger scale, and subjective happiness of 401 nursing students were measured. The differences between these groups were analyzed using t-tests and ANOVA tests. Correlations among academic efficacy, self-directedness, self-resilience and psychological states were calculated using Pearson's correlation coefficient. Multiple group analysis was conducted for assessing the interaction effects of academic efficacy, self-resilience and self-directedness. Subjective happiness and predictors of the study (self-directedness and ego-resilience) were positively correlated with statistical significance. The lower the self-directedness was, the higher the subjective happiness that is reduced by anger was. The higher the self-elasticity, the lower the degree of the subjective happiness that is reduced by anger. Since the moderating effect of self-directedness has been demonstrated in the relationship between anger and happiness, it is necessary to consider instituting proper pedagogy so that the educational method of enhancing self-directedness can be reflected in the field of nursing.

The purpose of this study is to investigate the effect of online psychiatric nursing practicum including virtual simulation on goal commitment, self-efficacy, critical thinking disposition, and problem solving ability of nursing students in the COVID-19 situation with difficult clinical practice. The subjects of this study were collected using an online questionnaire for third-year nursing students located in A city, and 31 students participated in the final. The results of this study showed that goal commitment and critical thinking disposition were improved in the post-test compared to the pre-test, but were not statistically significant. Self-efficacy (t=4.222, p<.001) and problem solving ability (t=6.807, p<.001) were signifincantly improved after than before online practicum. This findings indicate that online psychiatric nursing practicum including virtual simulation is effective in improving self-efficacy and problem solving ability. As it is difficult to perform nursing practice directly in the clinical field due to the recent COVID-19, it is expected that the limitations of online practicum can be overcome by utilizing various online contents including virtual simulations in online psychiatric nursing practicum.
