  • The purpose of this study was to investigate the relationship between job stress and coping style in college students. Participants were 314 students in a college. Data were collected using a self administered questionnaire. The survey was conducted from May 02, 2018 to May 28, 2018. There were statistically significant correlations between personality stress, family environmental stress, academic stress, school environment stress and emotion - centered coping style among sub - variables of job stress, Job anxiety stress was significantly correlated with social support seeking and emotion - centered coping style. Since college students' emotional stress coping style is related to depressive emotional and physical health problems, it is necessary to provide a psychological treatment program for early detection and coping with psychological support services, and a mixed service such as education, lecture, and camp. In addition, it is thought that strategic action skill training (plan, method, and technology) is needed to change from emotion - centered coping style to problem - solving style.

  • Marine traffic system is composed of ship, ship's operators and traffic environment The navigation channel is a part of traffic environment and the design of channel is a crucial factor for safe navigation This paper aims to evaluate ship-handling difficulty in straight and bend channels with an Environmental Stress model(ES-model). The ES-model is used to evaluate ship handling difficulty quantitatively on the basis of the ship operator's subjective judgement for safety in navigation The calculation of ES value was made on the basis of three factors such as channel width, ship's length and speed in straight and channels for safe navigation. The interrelation between factors was analyzed and reasonable design standards of channel width, ship's length and speed were proposed for safe navigation of ship in bend channel.

  • Adolescents whose families receive public assistance are primary interest in the article because they experience disproportionate shares of the burden of poverty and psychosocial stress and are at substantially high risk. To explain the psychosocial stresses of high-risk adolescents in poverty, this study analyzed the inter-relations and interactions of major variables: 1) stress related life condition, 2)individual & environmental resources, 3) emotional, behavioral, and academic adjustment. Data came from the survey of 351 students living in the families receiving public assistance. The major findings were as follows. High-risk adolescents in poverty suffered from chronic stresses related life conditions, including family environmental stress, financial & medical stress and stigmatic stress. As the effects of stress increased, depression/anxiety and delinquency of poor youth increased. The psychosocial adjustment of poor youth at risk was most effected by the stress resulted from family environment. Though they were suffered from stresses related poor environment, adolescents in poverty adjusted well, if they had individual and environmental resources including self-esteem democratic parenting and supportive school climate. In conclusion, this study confirmed that emotional, behavioral, and academic adjustment of adolescents in poverty was affected by various stresses from life conditions and individual and environmental resources. In order to improve adjustment of poor youth at risk, life conditions have to be improved and psychosocial resources to be increased. These findings have provided practical implications for social workers helping high-risk adolescents in poverty.

  • Glycine betaine (GB) is one of the compatible solutes that accumulate in the chloroplasts of certain halotolerant plants under salt or cold stress. The codA gene for choline oxidase, the enzyme that converts choline into GB, has been cloned from a soil bacterium Arthrobacter globiformis. We generated transgenic sweetpotato plants [Ipomoea batatas (L.) Lam] expressing codA gene in chloroplasts under the control of the SWPA2 promoter (referred to as SC plants) and evaluated SC plants under oxidative and drought stresses. SC plants showed enhanced tolerance to methyl viologen (MV)-mediated oxidative stress and drought stress due to induced expression of codA. At $5{\mu}M$ of MV treatment, all SC plants showed enhanced tolerance to MV-mediated oxidative stress through maintaining low ion leakage and increased GB levels compared to wild type plants. When plants were subjected to drought conditions, SC plants showed enhanced tolerance to drought stress through maintaining high relative water contents and increased codA expression compared to wild type plants. These results suggest that the SC plants generated in this study will be useful for enhanced biomass production on global marginal lands.

  • The purpose of this study was to determine the correlation between the COVID-19 related post-traumatic stress, nursing work environments, and the resilience among nurses in Tertiary General Hospitals. Data were collected from 155 nurses who directly cared for COVID-19 patients and were working at the K University D Hospital in D Metropolitan City using an online survey. The SPSS 28.0 program was used for data analysis. Based on the results of the survey, post-traumatic stress showed a significant negative correlation with the nursing work environments(r=-.17, p<.001), and the nursing work environments showed a significant positive correlation with the resilience of nurses(r=.20, p<.001). Through the results of this study, it is necessary to improve the nursing work environments for managing post-traumatic stress, to build an active support system by securing manpower from the government, and to develop and apply intervention programs for improving the resilience of nurses in the COVID-19 situation.

  • This study analyzed the healing effect of the design elements of healing environment from the perspective of environmental stress, which is one of the contents of environmental psychology. By examining the objective healing effects of the design elements of the healing environment, this study attempted to prepare a theoretical basis for contributing to the construction of a systematic and systematic healing environment. This study consists of three phases. Firstly, three environmental stress theories (Attention Recovery Theory, Evolutionary Psychology, and Environmental Stress Model) were examined to review the academic basis of which the theoretical concept of the healing environment has been derived and developed. Second, we analyzed 16 previous research on the design elements of healing environment and used them as an analysis framework of this study. Thirdly, 11 foreign studies that proved the healing effects of healing environment design elements through objective research methods were considered and analyzed as an analysis framework, and the basis for applying design elements in constructing healing environment was prepared. The research results are as follows. First, the concept of healing environment was developed from Lazarus's psychological stress theory and Ulrich's theory of evolutionary psychology, suggesting that it can be used as one of the noninvasive healing tools that affect stress reduction. Second, the healing environment design elements could be divided into 15 factors and categorized as physical environment, psychological environment, and social environment, and it was found that most of them were mentioned and studied in the previous research in order of nature-friendly, aesthetic, and openness. Third, most of the previous research on the healing effects of the design elements of the healing environment were related to natural affinity and aesthetics, and it was found that the visual elements of the healing environment could affect the actual stress reduction.

  • In order to develop transgenic potato plants with enhanced tolerance to multiple stress, we constructed the transformation vector expressing both superoxide dismutase and ascorbate peroxidase genes in chloroplasts under the control of a stress-inducible SWPA2 promoter. Transgenic potato plants (cv. Superior and Atlantic) were generated using an Agrobacterium-mediated transformation system. Transgenic potato plants were regenerated on MS medium containing 100mg/L kanamycin. Genomic Southern blot analysis confirmed the incorporation of foreign genes into the potato genome. When potato leaf discs were subjected to methyl viologen (MV) at 10 $\mu$M, transgenic plants showed higher tolerance than non-transgenic or vector-transformed plants. To further study we selected the transgenic plant lines with enhanced tolerance against MV. These plants will be used for further analysis of stress-tolerance to multiple environmental stresses.
