The vegetable brassicas are an important crop worldwide and are of significant commercial value. In order to ensure our targets for food security are met it is important that these crops are continually improved to increase sustainability of production, increase nutritional quality and reduce waste. Development of resistances against both biotic and abiotic stress are recognised as being key. Plant breeding plays a vital role in addressing these issues through the development of new and improved varieties. This continued improvement is becoming evermore dependent on our ability to identify and introgress beneficial alleles from 'exotic' germplasm into elite breeding material. Increasingly, more diverse germplasm such as those found in genebanks is being screened for benificial allelic variation, however, plant breeders often find it difficult to make use of such material due to the time required to remove undesirable characteristics from progeny due to linkage drag. This article describes how we have attempted to overcome this and develop resources that make the diversity available within the $Brassica$ $oleracea$ genepool more accessible.

Oxidative stress contributes to the onset of chronic diseases in various organs, including muscles. Morroniside, a type of iridoid glycoside contained in Cornus officinalis, is reported to have advantages as a natural compound that prevents various diseases. However, the question of whether this phytochemical exerts any inhibitory effect against oxidative stress in muscle cells has not been well reported. Therefore, the current study aimed to evaluate whether morroniside can protect against oxidative damage induced by hydrogen peroxide (H₂O₂) in murine C2C12 myoblasts. Our results demonstrate that morroniside pretreatment was able to inhibit cytotoxicity while suppressing H₂O₂-induced DNA damage and apoptosis. Morroniside also significantly improved the antioxidant capacity in H₂O₂-challenged C2C12 cells by blocking the production of cellular reactive oxygen species and mitochondrial superoxide and increasing glutathione production. In addition, H₂O₂-induced mitochondrial damage and endoplasmic reticulum (ER) stress were effectively attenuated by morroniside pretreatment, inhibiting cytoplasmic leakage of cytochrome c and expression of ER stress-related proteins. Furthermore, morroniside neutralized H₂O₂-mediated calcium (Ca²⁺) overload in mitochondria and mitigated the expression of calpains, cytosolic Ca²⁺-dependent proteases. Collectively, these findings demonstrate that morroniside protected against mitochondrial impairment and Ca²⁺-mediated ER stress by minimizing oxidative stress, thereby inhibiting H₂O₂-induced cytotoxicity in C2C12 myoblasts.

Statement of problem : The use of mouthguard is important as the leisure life is popular today. Purpose: The purpose of this study is to investigate the effect of a mouthguard on stress distribution in teeth, maxilla and mandible for maxilla impact. Material and methods: The 3-dimensional finite element model was based on a CT scan film of an average korean adult when the subject is using a customized mouthguard which was made with the Signature Mouthguard system of Dreve. The load was applied to the upper central incisor cervical area parellel impact force for 0.1sec(L1). The Von-mises stress analysis with a mouthguard and without a mouthguard was compared. Results: The results of this study were as follows: 1. Without the mouthguard, stress was concentrated on teeth and alveolar bone in all load conditions. 2. With the mouthguard. maximum stress value was decreased and stress was dispersed in all load conditions. 3. Stress extinction with the mouthguard was faster than without the mouthguard in all load conditions. Conclusion: We acknowledged that the mouthguard has a stress buffer effect as the maximum stress value was decreased and stress was dispersed when impact force was applied.

This study explores how the COVID-19 pandemic has changed family life and relationships as well as how these changes affect perceived stress among married men and women. This study investigated changes in family time use, household work, child care, leisure activities, income and expenditures along with relationships between spouses and children using a sample of 627 married persons surveyed online from May 19 to 25, 2020. The results showed that the amount of time spent on household work, child care, and family leisure have increased and that the perceived burden of household work and child care has also increased. Gender differences were found in time use, household work, and child care. Leisure activities have changed toward more time watching TV or online media and playing online games and less time on outdoor activities, shopping, and meeting friends. About 38% of respondents reported a reduction in household income and 22% reported an increase in household debt. The majority experienced no change in the quality of relationships with spouses and children, approximately 20% of the sample reported a positive change in relationships with spouses and children. The findings of multivariate regression indicated that change in work time, negative change in household economy, negative change in household work and negative change in relationships with spouses were associated with marital stress. However, this study found that negative changes in child care and in relationships with children did not affect stress among married parents with children in elementary or secondary school.

The purpose of this study was to investigate the factors having an influence on adjusting to the university life of freshmen and sophomore nursing students. The data was collected from questionnaires that were filled out by 150 nursing students in one school from November 1, 2018 to November 20, 2018. The data was analyzed by the SPSS 22.0 program (frequency, ANOVA, Pearson's correlation and multiple regression analysis). The mean score of university life adjustment was $75.85{\pm}9.43$ (range: 25~125). A negative correlation was found between adjustment to university life and stress, A positive correlation was found between adjusting to university life and self efficacy. Negative correlation was found between stress and self efficacy. The factors influencing the adjustment of freshmen and sophomore nursing students to university life were health promoting behavior (sleeping time, snacks, drinking, and leisure time or having a hobby), stress and self efficacy. In addition, health promoting behaviors, stress and self efficacy accounted for 13.9% of the variance in adjusting to university life. The results of this study suggest that health promoting behavior, stress and self efficacy are important to the adjustment to university life for freshmen and sophomore nursing students. Further research on improving health promoting behavior, reducing stress and improving self efficacy is warranted. An intervention program that includes these significant variables of such subjects should be developed to improve adjusting to the university life of nursing students.

The purpose of this study was to identify latent classes in changes of mothers' daily life stress over six years from multicultural families and to test its relationship with early adolescents' perceived neglecting parental attitudes and their academic achievements. For achieving this purpose, as the study sample 1,039 students were gathered from the 4th grade of elementary school to 3rd grade of middle school, using Growth Mixture Modeling, Multiple Group Analysis, and One-way ANOVA. The results were as follows. First, latent classes of mothers' daily life stress were categorized into three types: high-stable trajectory, moderate-changing trajectory, and low-changing trajectory. Second, these three types showed different characteristics in early adolescents' perceived neglecting parental attitudes and academic achievements. Third, early adolescents' perceived neglecting parental attitude were not significant determinants of the latent classes while academic achievements were. The findings of this study may provide a framework for understanding the relationships among mothers' daily life stress and early adolescents' perceived neglecting parental attitudes and their academic achievements in multicultural families and practical implications for providing social support to overcome daily life stress of mothers in multicultural families.
