We attempted to assess the impact of climate change on rice yields in Cambodia and to investigate adaptation strategies to climate change including more drastically shifting the planting dates and considering more fertilizer application levels. The potential yields of two wet season rice cultivars (Sen Pidao and Phka Rumduol) under two climate change scenarios in Cambodia were simulated using the CERES-Rice model. Field experiments conducted at the Cambodian Agricultural Research and Development Institute (CARDI), in 2010, 2011, and 2013 and climate variables from the HadGEM3-RA model were collected for this study. Compared with the baseline (1991-2000), yields of Sen Pidao rice will decrease under climate change and yields of Phka Rumduol rice could increase or decrease depending on fertilizer rates and the periods (2040s, 2050s, and 2080s). In general, the variations in the simulated effects of climate change on yields were more sensitive at fertilizer N100-N200 and less sensitive at fertilizer N0-N50. It is likely that forward shifts of planting date from the baseline plating date for the two cultivars in the future can be more benefitted than backward shifts. It is concluded that the CERES-Rice model can be useful to provide efficacious adaptation strategies in Cambodia.

Species are facing strong selection pressures to adapt to inhospitable high-altitude environments. Yaks are a valuable species and an iconic symbol of the Qinghai-Tibet Plateau. Extensive studies of high-altitude adaptation have been conducted, but few have focused on metabolism. In the present study, we determined the differences in the serum metabolomics between yaks and the closely related species of low-altitude yellow cattle and dairy cows. We generated high-quality metabolite profiling data for 36 samples derived from the three species, and a clear separation trend was obtained between yaks and the other animals from principal component analysis. In addition, we identified a total of 63 differentially expressed metabolites among the three species. Functional analysis revealed that differentially expressed metabolites were related to the innate immune activation, oxidative stress-related metabolism, and energy metabolism in yaks, which indicates the important roles of metabolites in high-altitude adaptation in yaks. The results provide new insights into the mechanism of adaptation or acclimatization to high-altitude environments in yaks and hypoxia-related diseases in humans.

Purpose : This study aims to identify the factors influencing field adaptation among nurses who have undergone department transfers, by examining the levels of and the relationships between their nursing work environment, interpersonal skills, grit, and field adaptation. Methods : The study involved 137 nurses who had experienced at least one department transfer within the last three years across two hospitals. Data analysis was performed using SPSS/WIN 29.0, involving descriptive statistics, means, standard deviations, independent t-tests, one-way ANOVA, Scheffé post-hoc tests, Pearson correlation coefficients, and multiple regression analysis (enter method). Results : Factors affecting field adaptation included the nursing work environment (β=.37, p<.001), interpersonal skills (β=.19, p=.021) and grit (β=.18, p=.025), with a total explanatory power of 31% (F=12.16, p<.001). Conclusion : This study contributes insights into effective nursing personnel management, offers foundational data for managing department transfers, and aims to improve the overall quality of nursing care.

Purpose: This study was conducted to identify relationships among circadian types, sleep quality, and adaptation to night shifts among nurses working on two or three day night duties. Methods: The participants were 199 ward nurses from two university hospitals in Gyeongnam province. Each nurse worked on two or three day night duties. Data were collected between September 24 and October 14, 2012 and analyzed using t-test, ANOVA, $Scheff{\grave{e}}$ test, Pearson correlation, and multiple regression with SPSS/WIN 14.0 program. Results: Mean scores for sleep quality and adaptation to night shifts was $4.92{\pm}1.46$ on a 10-point scale and $2.66{\pm}0.47$ on a 5-point scale respectively. There were no significant differences in sleep quality and adaptation to night shifts according to circadian types of nurses. There were significant correlation between sleep quality and adaptation to night shifts (r=.25, p<.001). Factors affecting adaptation to night shifts were preference for night shifts, and subjective health status, which together explained about 35% of the total variance. Conclusions: Nurses working on two or three day night duties had low level of sleep quality and adaptation to night shifts. It is necessary to improve preference for night shifts and subjective health status for improving adaptation to night shifts of nurse.

This study examined the relationship between depression, anxiety, stress, and adaptation to college life of international students living in South Korea during the COVID-19 pandemic and the factors affecting the adaptation to college life. This study was carried out between December 3, 2021, to January 25, 2022, on international students living in South Korea. The questionnaires were composed of self-reported questionnaires, and the survey URL was sent as text messages to international students who understood the purpose and rationale of this study and consented to participate in the survey. The data were analyzed using SPSS WIN 22.0, and t-test, ANOVA, Pearson's Correlation Coefficient, and hierarchical regression were performed. As a result of the study, the average score of the study subjects was 8.44 points for depression, 8.28 points for anxiety, and 9. 28 points for stress. factors with significant differences in adaptation to college life according to general characteristics were living means and smoking. The relationship between the main variables, it was significant with depression (r=-.785, p<.001), anxiety (r=-.593, p<.001), and stress (r=-.726, p<.001). There was one negative correlation. It was found that the higher the depression, anxiety, and stress, the lower the college life adaptation. Lastly, depression (β=-.666, p<.001) was the factor affecting foreign students' adaptation to college life, and the explanatory power was 62%. Therefore, for international students to adapt to college life, it is necessary to establish an institutional strategy to detect depression, a negative psychological emotion, at an early stage and to systematically manage it. Also, it is necessary to find an intervention plan to relieve depression that can be applied in social isolation situations due to the spread of infectious diseases. Research confirming the intervention effect should be upgraded.

Zinc plays a key role in genetic expression, cell division, and growth and is essential for the function of more than 200 enzymes; effects of zinc deficiency induce many syndromes, including abnormal visual adaptation. The pigment epithelium (EP) contains high concentrations of zinc in humans and in animals and it participates in threshold elevation, visual sensitivity increment, and acceleration of rhodopsin regeration during visual adaptation. The origin of c-wave of electroretinogram(ERG) is not only pigment epithelium as shown in present research, but also other cell layers, perhaps the photoreceptors. We propose zinc as a candidate for an internal messenger which participates in signal amplification.

Purpose: This study examined the effects of self-leadership and critical thinking disposition on adaptation to college among nursing students. Methods: A descriptive study was conducted with 325 nursing students using a self-report questionnaire. Data were analyzed using a t-test, one way ANOVA, $Scheff{\dot{e}}$ test, Pearson correlation coefficients, and stepwise multiple regression analysis with SPSS 20.0. Results: The mean score of college adaptation was 3.22. Significant predictor variables affecting adaptation to college were satisfaction in major (${\ss}=.45$, p<.001), behavior-focused strategies (${\ss}=.16$, p<.001), leadership level (${\ss}=.15$, p=.003), and grade (${\ss}=.11$, p=.016). The explanation power of this regression model was 32.2% and was statistically significant (F=64.60, p<.001). Conclusion: The results of this study indicated that an effective college adaptation program should be developed by including improvement of satisfaction in major, behavior-focused strategies, and leadership level.
