This study looked into the effects of acceptance and commitment therapy(ACT) program on the premenstrual symptoms, attitudes toward menstruation and perceived stress, in females in their 20's suffering from premenstrual syndrome(PMS). Among the 263 students from 3~4 year universities, 21 were selected as participants. 7 were assigned to the acceptance and commitment therapy(ACT) group, 7 were assigned to the cognitive behavior therapy(CBT) group, and 7 were assigned to the control group. As a result, emotional factor from the premenstrual symptoms has significantly decreased more in the acceptance and commitment therapy(ACT) group, and the cognitive behavior therapy(CBT) group in comparison to the control group. In regards to attitudes toward menstruation, there were no statistical significance in the acceptance and commitment therapy(ACT) group, however there were positive changes, and the cognitive behavior therapy(CBT) group displayed significant change in the follow-up study. In perceived stress, acceptance and commitment therapy(ACT) group displayed more significant decrease than the control group and the cognitive behavior therapy(CBT) group, and that level remained unchanged until the follow-up study.

The purpose of this study is to develop cognitive behavioral therapy(CBT) to improve the parenting efficacy of married immigrant women, and verify its effectiveness. In the CBT of this study, behavioral technique was added to cognitive reconstruction based on cultural context in order to improve parenting efficacy. The study selected 28 married immigrant women, and randomly divided them into a CBT group(10), a general treatment group(8) and a control group(10). The CBT and the general treatment programs consisted of 10 sessions, approximately 2 hours in duration. The results of the study were as follows. 1) The level of parenting efficacy was improved significantly in the CBT and the general treatment group. 2) The level of negative automatic thoughts and dysfunctional parenting thoughts was significantly decreased only in the CBT group. 3) In the CBT and the general treatment group, the level of parenting stress and acculturative stress was decreased while the level of psychological well-being improved. On the other hand, the level of parent-adolescent communication was improved significantly only in the CBT group. 4) In comparison with the general treatment group, the CBT group showed higher parenting efficacy and lower automatic thoughts and dysfunctional parenting thoughts. This study has significance in its attempt to develop a parent training program to improve the parenting efficacy of married immigrant women by integrating behavioral modification and communication skills training focused on cognitive reconstruction of parenting-related negative thoughts and beliefs in application of the CBT paradigm.

Several lines of evidence suggest that endoplasmic reticulum (ER) stress plays a critical role in the pathogenesis of many neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. Protein tyrosine phosphatase 1B (PTP1B) is known to regulate the ER stress signaling pathway, but its role in neuronal systems in terms of ER stress remains largely unknown. Here, we showed that rotenone-induced toxicity in human neuroblastoma cell lines and mouse primary cortical neurons was ameliorated by PTP1B inhibition. Moreover, the increase in the level of ER stress markers ($eIF2{\alpha}$ phosphorylation and PERK phosphorylation) induced by rotenone treatment was obviously suppressed by concomitant PTP1B inhibition. However, the rotenone-induced production of reactive oxygen species (ROS) was not affected by PTP1B inhibition, suggesting that the neuroprotective effect of the PTP1B inhibitor is not associated with ROS production. Moreover, we found that MG132-induced toxicity involving proteasome inhibition was also ameliorated by PTP1B inhibition in a human neuroblastoma cell line and mouse primary cortical neurons. Consistently, downregulation of the PTP1B homologue gene in Drosophila mitigated rotenone- and MG132-induced toxicity. Taken together, these findings indicate that PTP1B inhibition may represent a novel therapeutic approach for ER stress-mediated neurodegenerative diseases.

Immigration of Koreans to the United States has increased since the 1960's. Adjusting to life in the United States produces a great deal of stress for immigrants. Despite better economic opportunites, many see the U.S. culture as threatening to their family and cultural values. Differences in culture, language, expectations and social behavior can lead to misunderstandings between health care providers and clients. These misunderstanding can leaf to frustration on the part of each. The ultimate result of this is that often Korean-immigrants do not get their health care needs met and stress response symptoms can lead to disease if there is no appropriate care. To determine the health care needs and concerns of Korean-Americans, a health needs assessment is needed. Appropriate and adequate information about the health care needs of these individuals is important as it relates to American policy changes allowing greater numbers of immigrants to enter the U.S. The purpose of this prospective study was to describe Korean-American stress response. This study focused on the primary presenting problems for which subjects reported having sought care. These included a variety of stress-related symptoms, including peripheral manifestations, cardiopulmonary symptoms, central-neurological symptoms, gastrointestinal symptoms, muscle tension, habitual patterns, depression, anxiety, emotional irritability and cognitive disorganization. Of the 300 subjects who entered the study, 80% (N＝223) completed the questionnaire in full. Demographically, the percentage of females and males was 50% each and they ranged in age from 20 to 69 years. Ninety percent of the subjects were highly educated, 25% owners of business, 25% white collar professionals, 15% employed in sales or as skilled /unskilled labor, 30% had no occupation : and 5% were housewives or students. The SOS inventory is designed to quantify self-perception of behavioral, cognitive, and physiological components of the stress response. It consisted of 94 items divided into 10 subscales. The result of this study are as follows : The total mean 505 of all subjects (N＝223 was .8129 ; the mean 505 for male(N＝114) was .7665 and for females, (N＝108) .8594. The level of symptoms for central-neurologic and muscle tension was higher for than for males. The highest stress response of all subjects was emotional irritability symptoms(1.0644) : the lowest stress response of all subjects was peripheral manifestation symptoms.

This study examined the cognitive emotion regulation strategies and professional quality of life to identify factors affecting the professional quality of life in hospital nurses. The participants were 176 staff nurses working at a university hospital in Seoul. Data were collected using a structured online questionnaire from March 3 to 16, 2020. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis using SPSS 25.0. The cognitive emotion regulation strategies of hospital nurses were identified as factors affecting the professional quality of life. Adaptive cognitive emotion regulation strategy (β=.501, p<.001) had significant effects on the participants' compassion satisfaction, and the explanatory power was 24.8%. The variables affecting burnout were adaptive cognitive emotion regulation strategy (β=-.435, p<.001), maladaptive cognitive emotion regulation strategy (β=.427, p<.001), and educational level (β=.188, p=.046), and the explanatory power was 36.8%. In addition, the maladaptive cognitive emotion regulation strategy (β=.502, p<.001) had significant effects on secondary traumatic stress of the participants, and the explanatory power was 24.4%. Based on this, it is necessary to develop programs to improve the professional quality of life of hospital nurses, focusing on acquiring adaptive cognitive emotion regulation strategies and using less maladaptive strategies.

Firefighters wear Personal Protective Equipment (PPE) for protection from environmental hazards. However, due to the layers of protective functions, the PPE inevitably adds excessive weight, bulkiness, and thermal stress to firefighters. This study investigated the adverse impact of wearing PPE as an occupational stressor on the firefighter's cognitive functioning. Twenty-three firefighters who had been involved in firefighting at least for 1 year were recruited. The overall changing trend in the firefighter's cognitive functioning (short-term memory, long-term memory, and inductive reasoning) was measured by the scores of three standardized cognitive tests at the baseline and the follow-up, after participating in a moderate-intensity physical activity, wearing a full ensemble of the PPE. The study findings evinced the negative impact of the PPE on the firefighter's cognitive functioning, especially in short-term memory and inductive reasoning. No significant influence was found on the firefighter's long-term memory. The results were consistent when the participant's age and BMI were controlled. The outcomes of the present study will not only fill the gap in the literature, but also provide critical justification to stakeholders, including governments, policymakers, academic communities, and industry, for such efforts to improve human factors of the firefighter's PPE by realizing the negative consequences of the added layers and protective functions on their occupational safety. Study limitations and future directions were also discussed.

College students experience more cyber bullying than youth and cyber bullying on college students may be more harmful than youth. But many studies of cyber bullying have been conducted in youth, but little has been studied for college students. Therefore, this study investigated the negative effects of college students' cyber bullying experience on cognitive processing ability and emotional states. The social support of friends has a buffering effect that prevents stress and reduces the influence on external damage in stressful situations. But the impact of parental social support is controversial. Traditionally, the social support of parents has been claimed to mitigate the negative effects of external damage. Recently, however, it has been argued that parental social support, without considering the independence and autonomy needs of college students, does not alleviate the negative effects. Therefore, this study examined how the social support of friends and parents moderate the negative impact of cyber bullying. The results show that the more college students experience cyber bullying, the lower their cognitive processing ability and emotional states. And, the higher the social support of friends, the lower the harmful impacts of cyber bullying on cognitive processing ability and emotional states. But, the higher the social support of parents, the higher the harmful impacts of cyber bullying on cognitive processing ability and emotional states.

Purpose: According to Lazarus & Folkman (1984), appraising a stressor as a threat is associated with negative psychological and physical adjustment, whereas appraising a stressor as a challenge is positive psychological and physical adjustment. This study examined how cognitive appraisal of PTCA(heart disease threat and treatment appraisal) related to the cardiac risk reduction behaviors(smoking cessation, low salt and low cholesterol diet, regular exercise and stress management) 6 weeks following discharge. Method: Data were collected from 50 subjects with successful primary PTCA. Result: Heart disease threat was negative related to treatment appraisal (r=-0.240, p=0.046). Psychological well-being was negative related to heart disease threat (r=-0.317, p=0.012) and positive related to treatment appraisal(r=0.402, p=0.002). The cardiac risk reduction behaviors score was negative related to heart disease threat(r= -0.296, p=0.018) and positive related to treatment appraisal(r=-0.291, p=0.020). Conclusion: More negative appraisal was related to lower the cardiac risk reduction behaviors score. But more positive appraisal was related to higher the cardiac risk reduction behaviors score. So, there is a need to develop the cognitive-behavioral intevention that increase the coping strategy to replace with positive appraisal.
