Arthritis patients living in a rural town are thought to have more problems in terms of life stress, social support, and depression than those living in an urban city. But there were few studies which investigated the status of arthritis patients living in a rural town. This study investigated how much life stress they got, which life events were perceived as stress, what kind of social support were most perceived, and how much they were depressed. Fifty six arthritis patients were surveyed using structured questionnaire. Life stress, social support, and depression were assessed using the following scales: Life changes scale, Duke's short scale to measure social support, and CES-D(Center for Epidemiologic Study- Depression), respectively. They were found to perceive life stress in home-work, health and work, in order. And they were found to perceive relatively good social support. But they sot most of social support from their family members especially their spouses and children. Lastly, it was found that they were moderately depressed. Based upon these results, it is suggested that integrative rehabilitation programs which provide professional support and reduce depression are necessary for arthritis patients living in rural towns.

The purposes of this study were to find correlation between family abuse experience, family stress, social support, family resiliency and happiness in university students, and to explore the mediating role of social support and family resiliency between family abuse experience, family stress and happiness. The subjects were 295 university students. The data were analyzed by means of frequency analysis, Pearson's correlation and structural equation modeling with SPSS and AMOS. Instruments were Lee's(2010) Happiness Scale for university students, Strauss'(1988) CTSP(Parent-Child Conflict Tactics Scale), McCubbin's(1981) FILE(Family Inventory of Life Events and Changes), Yu's(2004) Family resiliency of Family Health Scale and Park's(1985) Social Support Scale. The major findings were as follows; Family abuse experience was positively correlated with family stress and negatively correlated with social support, family resiliency and happiness. Family stress was negatively correlated with family resiliency. Social support and family resiliency were positively correlated with happiness. Family abuse experience positively influenced family stress and negatively influenced social support and family resiliency. Social support positively influenced family resiliency and happiness. Family stress negatively influenced family resiliency. Family resiliency positively influenced happiness. Thus education program and counseling should be provided to increase happiness and family resiliency, and social support should be provide to increase the quality of life for university students.

Background and objective: This study was conducted to investigate the effects and preferences of horticultural therapy programs for stress relief according to MBTI personality types (Judging and Perceiving types) of female undergraduate students. Methods: The participants were divided into 15 Judging and 15 Perceiving types based on lifestyle preferences of the MBTI personality test, and a total of 30 participants participated in the horticultural therapy programs for 6 sessions. Results: Both Judging and Perceiving types showed a significant decrease in stress after participating in the horticultural therapy programs. Among the 8 life stress subfactors, Judging types showed significant stress relieving effects in 5 subfactors (relationship with the opposite sex, relationship with family, economic problems, future problems, value problems), while Perceiving types showed stress relieving effects in only 3 subfactors (relationship with family, economic problems, future problems). However, the changes in stress relief of 8 subfactors were not significantly different between the two personality types. The most preferred program for the Judging types was 'Making a flower basket', while the most preferred ones for the Perceiving types were 'Planting monstera', and 'Making preserved lemons with marigold', suggesting that the preferences varied depending on personality types. Conclusion: Therefore, it is necessary to develop suitable horticultural therapy programs for different subjects based on their personality types to enhance the effect of the programs on the subjects.

The plant-specific NAC transcription factors control various biological processes, including plant development and stress responses. We have isolated an ANAC032 gene, one of the NAC transcription factor family, which was highly activated by multi-abiotic stresses, including high salt and drought in Arabidopsis. Here, we generated transgenic plants constitutively expressing ANAC032 and its knockout to identify the functional roles of ANAC032 in Arabidopsis under abiotic stress responses. The ANAC032-overexpressing plants showed enhanced tolerance to salinity and drought stresses. The anac032 knockout mutants were observed no significant changes under the high salt and drought conditions. We also monitored the expression of high salt and drought stress-responsive genes in the ANAC032 transgenic plants and anac032 mutant. The ANAC032 overexpression upregulated the expression of stress-responsive genes, RD29A and ERD10, under the stresses. Thus, our data identify that transcription factor ANAC032 plays as an enhancer for salinity and drought tolerance through the upregulation of stress-responsive genes and provides useful genetic traits for generating multi-abiotic stress-tolerant forage crops.

Insects affect crop harvest yield and quality, making plant response mechanisms to insect herbivores a heavily studied topic. However, analysis of plant responses to honeybees is rare. In this study, comprehensive metabolic profiling of Arabidopsis thaliana exposed to honeybees was performed to investigate which metabolites were changed by the insect. A total of 85 metabolites-including chlorophylls, carotenoids, glucosinolates, policosanols, tocopherols, phytosterols, β-amyrin, amino acids, organic acids, sugars, and starch-were identified using high performance liquid chromatography, gas chromatography-mass spectrometry, and gas chromatography-time-of-flight mass spectrometry. The metabolite profiling analysis of Arabidopsis exposed to honeybees showed higher levels of stress-related metabolites. The levels of glucosinolates (glucoraphanin, 4-methoxyglucobrassicin), policosanols (eicosanol, docosanol, tricosanol, tetracosanol), tocopherols (β-tocopherol, γ-tocopherol), putrescine, lysine, and sugars (arabinose, fructose, glucose, mannitol, mannose, raffinose) in Arabidopsis exposed to honeybees were higher than those in unexposed Arabidopsis. Glucosinolates act as defensive compounds against herbivores; policosanols are components of plant waxes; tocopherols act as an antioxidant; and putrescine, lysine, and sugars contribute to stress regulation. Our results suggest that Arabidopsis perceives honeybees as a stress and changes its metabolites to overcome the stress. This is the first step to determining how Arabidopsis reacts to exposure to honeybees.

This study analyzed the relationships between changes in family life due to COVID-19, daily stress, work-family balance conflict and the job satisfaction of married working women. The subjects of this study were 1,934 married women wage workers who were extracted from the data of the 8th year of the female family panel survey surveyed in 2020. Path analysis was conducted to analyze the hypothesis using AMOS 21.0. The study results revealed that family life change doesn't directly affect work-family balance conflict, but increases job satisfaction. But family life change indrectly affects increasing work-family balance conflict and decreasing job satisfaction through daily stress. And daily stress affects increasing work-family balance conflict and decreasing job satisfaction. Additionally work-family balance conflict has an effect on reducing job satisfaction. Based on the results, practice and policy suggestions were made to reduce work-family balance conflict and increase job satisfaction of married working women.

This paper on planning constant accelerated life test is assumed that parameters for a lognormal life distribution are depended on changes of stresses. The proposed test plans are optimum in that they minimize the asymptotic variance of maximum likelihood estimator of a specified quantile at the design stress. The optimal amount of low stress level ${\xi}_{L}$ and optimal sample proportion ${\pi}$ to be allocated at low stress level are obtained when the ratio of scales at high stress level and design stress level is unknown.

The study aimed to understand medical students' experiences of emotional changes, including their method of adapting to experiences, and the effect of the experiences in shaping their identities. We interviewed 12 medical students who were finishing their 1-year clinical internship in 2016. Data on their opinions and reasons for emotional changes during their school life were obtained. The descriptive phenomenological approach was applied to analyze the interviews. Their stress came from disappointment in themselves, competitive environment, observing a change in their personalities, meeting their parents' expectations, and interpersonal relations. The interviewees adjusted to the medical study by exercising self-control in their studies and daily lives, by practicing self-acceptance and observing their state of mind, and by breaking free from the competition-driven environment and obsession with grades. In addition, they cultivated endurance and found external support. Finally, they achieved self-efficacy and were comfortable in their identity as medical students. They still had to address the stress from working relationships and the difficulty in balancing studies and life. The medical students' self-evaluation and compulsive tendencies increased during the medical course due to the burden of studies. They evolved by learning self-control and introspection and seeking ways to adapt. Understanding this growth process of medical students will improve student support in medical schools.

Adverse environmental conditions such as drought, high salt and cold/freezing are major factors that reduces crop productivity worldwide. According to a survey, $50-80\%$ of the maximum potential yield is lost by these 'environmental or abiotic stresses', which is approximately ten times higher than the loss by biotic stresses. Thus, Improving stress-tolerance of crop plants is an important way to improve agricultural productivity. In order to develop such stress-tolerant crop plants, we set out to identify key stress signaling components that can be used to develop commercially viable crop varieties with enhanced stress tolerance. Our primary focus so far has been on the identification of transcription factors that regulate stress responsive gene expression, especially those involved in ABA-mediated stress response. Be sessile, plants have the unique capability to adapt themselves to the abiotic stresses. This adaptive capability is largely dependent on the plant hormone abscisic acid (ABA), whose level increases under various stress conditions, triggering adaptive response. Central to the response is ABA-regulated gene expression, which ultimately leads to physiological changes at the whole plant level. Thus, once identified, it would be possible to enhance stress tolerance of crop plants by manipulating the expression of the factors that mediate ABA-dependent stress response. Here, we present our work on the isolation and functional characterization of the transcription factors.
