This study attempted to explore the experience related to the work-family balance of working moms during the COVID-19 period. To this end, in-depth interviews were conducted by recruiting 17 part-time and full-time working moms with at least 1 child under the age of 13. As a result of analyzing the data using the method of grounded theory, 106 concepts, 50 subcategories, and 24 categories were derived. The central phenomenon that working moms experienced in the process of work and family balance were "physical and emotional exhaustion", "anxiety and guilt about not doing well in situations of role conflicts between various roles", "job crisis experienced by working mothers" and "deepening family conflicts". The process of working moms overcoming the central phenomenon and achieving work-family balance was identified as five stages: the 'shock and confusion stage', the 'struggling stage', the 'actively coping and making compromise stages', the 'acceptance stage', and the 'post-traumatic growth stage'. Based on these results, discussions on the work-family balance of working mothers during the COVID-19 period was dealt as well as suggestions for follow-up studies.

This study assessed the biochemical methane potential (B_u-P) of three grass species-Poa pratensis (PP), Zoysia japonica (ZJ), and Agrostis stolonifera (AS). B_u-P values were determined as 0.330 Nm³/kg-VS_added for PP, 0.297 Nm³/kg-VS_added for ZJ, and 0.261 Nm³/kg-VS_added for AS. Notably, PP exhibited superior suitability for methane production. The investigation also examined the impact of silage storage duration on PP grass clippings, revealing a 19% decline in B_u-P from an initial value of 0.269 Nm³/kg-VS_added on day 0 to 0.217 Nm³/kg-VS_added on day 180. Throughout the storage period, there were significant increases in neutral detergent fiber (NDF), acid detergent fiber (ADF), and crude protein (CP) contents, rising from 67.59%, 39.68%, and 3.02% on day 0 to 77.12%, 54.65%, and 6.24% on day 180, respectively. These findings highlight the influence of storage duration on the anaerobic digestibility of PP grass clippings. To effectively utilize grass clippings as a renewable resource for methane production, further studies considering factors such as initial moisture content, pretreatment methods, and potential effects of residual pesticides are necessary to optimize anaerobic digestion efficiency for herbaceous biomass.

The purpose of this study is to investigate the levels of academic stress, sociality, and self-directed learning in nursing students, and to examine the relationship between the variables. Data were collected using a self-administered questionnaire from 208 students in the first and second years of a nursing program. This study was performed from December 5 to December 10, 2015. The data were analyzed with SPSS WIN 18.0 software (SPSS Inc., Chicago, IL, USA). The results were as follows. The mean score of academic stress was $3.20{\pm}0.53$, that of sociality was $2.91{\pm}0.25$, and that of self-directed learning was $3.33{\pm}0.33$. There was a negative correlation between academic stress and self-directed learning (r=-0.16, p=0.024) and a positive correlation between sociality and self-directed learning (r=0.17, p=0.015). Higher academic stress correlated with lower self-directed learning, while higher sociality correlated with higher self-directed learning. The results indicate that the levels of academic stress, sociality, and self-directed learning in nursing students can influence the quality of nursing education. Thus, there is a need to develop programs to reduce academic stress and to help improve sociality and self-directed learning for nursing students.
