Mental Stress Assessment Using Ultra Short Term HRV Analysis Based on Non-Linear Method.

Mental stress is on the rise as one of the major health problems in modern society. It is important to detect and manage mental stress to prevent various diseases caused by stress and to maintain a healthy life. The purpose of this paper is to present new heart rate variability (HRV) features based on empirical mode decomposition and to detect acute mental stress through short-term HRV (5 min) and ultra-short-term HRV (under 5 min) analysis. HRV signals were acquired from 74 young police officers using acute stressors, including the Trier Social Stress Test and horror movie viewing, and a total of 26 features, including the proposed IMF energy features and general HRV features, were extracted. A support vector machine (SVM) classification model is used to classify the stress and non-stress states through leave-one-subject-out cross-validation. The classification accuracies of short-term HRV and ultra-short-term HRV analysis are 86.5% and 90.5%, respectively. In the results of ultra-short-term HRV analysis using various time lengths, we suggest the optimal duration to detect mental stress, which can be applied to wearable devices or healthcare systems.

The Effects of Perfectionism and Dispositional Self-focused Attention of Novice Counselor on Psychological Burnout: Moderated Mediating Effects of Cognitive Emotion Regulation Strategies.

The current study investigated the mediation effect of self-focused attention on the relationship between South Korean novice counselors' perfectionism and psychological burnout. We also examined whether cognitive emotion regulation strategies moderated the mediation effect of self-focused attention with a sample of 208 South Korean novice counselors. Moderated mediation was tested with the PROCESS 2.16.3 macro for SPSS and the index of moderated mediation. Bootstrapping analyses were used to examine the mediation effect of self-focus on the relationship between perfectionism and psychological burnout. A hierarchical multiple regression analysis was also conducted to examine the moderation of emotion regulation strategies. Findings indicate that self-focused attention partially mediated the relationship between perfectionism and psychological burnout. Moreover, the indirect effect of perfectionism on psychological burnout through self-focused attention varied depending on levels of adaptive emotion regulation strategies. We present implications for counseling and suggestions for future research in an international context.

Art therapists' fear of COVID-19, subjective well-being, and mindfulness.

The COVID-19 pandemic has hit face-to-face service fields, including art therapy. The present study examined changes in Korean art therapists' subjective well-being between the pre- and during pandemic periods. We also investigated whether the fear of COVID-19 affected art therapists' subjective well-being and verified the mediating effect of mindfulness on the relationship between COVID-19 fear and subjective well-being. We used the existing data of 203 Korean art therapists' subjective well-being, and recruited 132 new participants. The participants were Korean art therapists and art therapy students who completed a subjective well-being questionnaire, a Fear of COVID-19 scale, and a mindfulness questionnaire. The results indicated lower levels of subjective well-being during the COVID-19 period than pre-pandemic. Furthermore, we confirmed that the fear of COVID-19 lowered subjective well-being, with mindfulness mediating the relationship. This study discusses core components of mindfulness, decentering, and embodiment as attributes shared with art therapy. Our results highlight the importance of dispositional mindfulness to foster subjective well-being during the pandemic.

A Moderation Analysis of Perfectionism, Cultural Sensitivity, and Counselors-In-Training Attitudes Toward Non-Dominant Sexual Identities.

The purpose of this study was to explore the moderating effect of maladaptive perfectionism on the relationship between cultural sensitivity and counselors-in-training attitudes toward non-dominant sexual identities. A total of 209 counseling graduate students participated in the study. Results showed that cultural sensitivity predicted attitudes toward individuals who identify with a non-dominant sexual identity after controlling for age. Also, a regression analysis demonstrated that maladaptive perfectionism is a moderator in the relationship between cultural sensitivity and attitudes toward individuals who identify with a non-dominant sexual identity among counselors-in-trainings. Implications in the counseling and education field and suggestions for future research are discussed.

Exploring the relationships between personality and color preferences.

Introduction: This study set out to quantitatively examine the relationship between personality and color, focusing on connotations and preference. Method: A total of 854 Koreans, aged from 20 to 60, participated in the study. They indicated which colors they associated with various personality words, completed the Ten Item Personality Inventory, and ranked their color preferences. We analyzed the data using frequency analysis, correlation analysis, t-tests, regression analysis, and cluster analysis. Results: The analyses revealed that all five personality types have characteristic color associations. Through regression analysis, we found that color preference can significantly predict personality. The comparison among personality groups produced by cluster analysis confirmed that people with strong specific personalities prefer the colors that symbolize their personalities. Discussion: This study's findings highlight the relationship between personality and color preference. The limitations and suggestions for future studies are also presented.

Examining the Relationships Among Concealment Tendencies, Illness Attitudes, Belief in a Just World, and Cognitive Flexibility.

The purpose of this study was to verify the relationships among concealment tendencies, illness attitudes, belief in a just world, and cognitive flexibility. The participants were 418 Korean and 400 Chinese adults. We conducted correlational analysis, structural equation modeling, and verification of mediating effects. We found that cognitive flexibility-control factor fully mediated the relationship between concealment tendencies and illness attitudes for Korean participants and partially mediated the relationship for Chinese participants. The relationship between concealment tendencies and cognitive flexibility-alternatives factor differed across participants' country of origin. For Chinese participants, cognitive flexibility-alternatives fully mediated the relationship between concealment tendencies and belief in a just world. These differences might stem from the countries' different social systems, values, and attitudes. Finally, we discuss this study's implications and limitations.

Examining the Relationships Among Parental Overprotection, Military Life Adjustment, Social Anxiety, and Collective Efficacy.

The purpose of this study was to verify the relationships among parental overprotection (PO), military life adjustment (MLA), social anxiety, and collective efficacy (CE). There have been studies examining the influence of each of these variables in isolation, but no study has examined these variables simultaneously. Two hundred and thirty-one male conscript soldiers participated in the study. Results indicated that all four variables were correlated with one another. Through hierarchical regression analysis, we determined that social anxiety fully mediated the relationship between PO and MLA. Furthermore, we found that CE moderated the relationship between PO and social anxiety. Finally, we confirmed the moderated mediation effect of CE in our proposed model. We discuss the implications and limitations of this model.

Influences of the Differences Between Mothers' and Children's Perceptions of Parenting Styles.

In this study, we explored the differences between mothers' and children's perceptions of mothers' parenting styles (DMCP of MPS) and examined the effects of these differences on children's depression, aggression, and ego-resilience. A total of 233 pairs of mothers and teen-aged children participated in the study. Our analysis produced four main findings. First, the mothers perceived their parenting attitudes as more rational and affectionate than their children did; children whose mothers rated their parenting styles more favorably had higher levels of depression and aggression and lower ego-resilience. Second, the correlation analysis and the structural equation model verification confirmed that as the DMCP of MPS increased, children's levels of depression and aggression increased, and their ego-resilience decreased. Third, ego-resilience partly mediated the relationship between DMCP-Rationality and depression. Lastly, we found that ego-resilience and depression had dual mediation effects on the relationship between DMCP-Rationality and children's aggression. This paper concludes with a discussion of the implications of these findings and suggestions for future studies.

The Relationship Between Army Soldiers' Perceived Stress and Army Life Adjustment: Focusing on the Mediating Effect of Stress Response and the Moderating Effect of Cohesion.

INTRODUCTION: South Korea maintains a mandatory military duty, and high percentage of conscript soldiers have difficulty adjusting to military life. The purpose of this study is to investigate the mediating effect of the stress response on the relationship between soldiers' perceived stress and military life adjustment and to clarify the moderating effect of cohesion on this relationship. MATERIALS AND METHODS: The study's participants were 285 Korean military soldiers who are obliged to serve in the military and they completed the Perceived Stress Scale, the Stress Response Scale, the Military Life Adjustment, and the Group Cohesion Scale. Analysis methods included descriptive statistics, correlation analysis, path analysis, bootstrapping, collinearity statistic, and hierarchical regression analysis. This research obtained the approval of the institutional review board of the university (HYI-18-229-1). RESULTS: First, a partial mediation effect of the stress response was found in the relationship between soldiers' perceived stress and military life adjustment. That is, a high level of soldiers' perceived stress was related to their military life maladjustment. Moreover, the greater the level of soldiers' perceived stress, the greater the stress response, and, in turn, the greater the military life maladjustment. Second, we found the moderating effect of cohesion in the relationship between stress perception and military life adjustment. CONCLUSIONS: The stress perceived by soldiers not only directly affects their military life adjustment but also indirectly affects their adjustment through the stress responses. In addition, soldiers' levels of adjustment to military life change significantly based on cohesion levels only when they perceive less stress.

Social relationship changes in victim families due to a social disaster: Experiences of student victims' families in the South Korean Sewol ferry disaster.

The Sewol ferry incident on April 16, 2014 in South Korea claimed the lives of 304 individuals, including about 250 high school students on a school trip. The majority of South Korean citizens were watching live updates on the capsized Sewol ferry, anxiously watching on TV how the vessel fully sunk over time. They were desperately hoping for the rescue of the survivors inside. However, their anxiety had become shock, anger, and helplessness, and the disaster has become a daunting, collective trauma, not just to the victims and their families, but also to the citizens who were exposed only through the media. In this study, we interviewed victims' families two years after the incident. We explored how they have experienced changes in their social relationships. We conducted semi-structured interviews of 54 family members of the student victims. We qualitatively examined the data applying a thematic analysis. Changes in their social relationships were largely divided into the relationships in the proximal environment and the relationships in distal environments. The former included subcategories such as immediate family, coworkers, friends, relatives, survived students and their parents, and concepts corresponding to each subcategory. The latter involved subcategories such as neighbors, other citizens, the victims' family committee, government, and society, and concepts subject to each subcategory. Based on these findings, rehabilitation plans for trauma victims and their families should take into account the significant changes in their social relationships and the further consequences of those changes.

Parent involvement in school: English speaking versus Spanish speaking families.

The purpose of the present study was to explore the relationships between three predictor variables (attitude toward school, parent-child communication, and school commitment action) and the criterion variable (parent involvement) in a representative sample and to examine if these relationships were consistent across three groups (English speaking Caucasian family, English speaking Latino family, and Spanish speaking Latino families). Using a national database (N = 9.841), multi-group SEM analyses were conducted to investigate the relationship between three predictor variables and the criterion variable in three family groups. While all three predictor variables significantly predicted parent involvement in English speaking Caucasian and Latino families, only two variables (parent-child communication and school commitment actions), significantly predicted parent involvement in Spanish speaking Latino families. The results of this study suggest that when administrators, teachers and counselors in school strive to share specific school-related information with Latino families, Spanish speaking families are more likely to become involved with schools.

El objetivo de este estudio fue evaluar las relaciones entre tres variables predictoras (actitud hacia la escuela, comunicación padres-hijos, y acciones de compromiso escolar) y una variable criterio (implicación de los padres) para examinar si esas relaciones eran consistentes en una muestra representativa de tres grupos (familias angloparlantes caucásicas, familias angloparlantes latinas, y familias hispanoparlantes latinas). Mediante una base de datos nacional (N = 9,841) y análisis multigrupo (SEM) se evaluó la relación entre las tres variables predictoras y la variable criterio en los tres tipos de familias. Los resultados indicaron que las variables predictoras eran un indicativo de la implicación de los padres en las familias angloparlantes caucásicas, y latinas, sólo dos de esas variables (comunicación padres-hijos y acciones de compromiso escolar) predecían la implicación de los padres en las familias hispanoparlantes. Asimismo, sugieren que cuando administradores, profesores y consejeros de la escuela se esfuerzan en compartir información específicamente relacionada con la escuela con familias latinas, los hispanohablantes muestran una mayor probabilidad a implicarse en todo el proceso educativo de sus hijos (AU)

A reliability generalization study of the Frost Multidimensional Perfectionism Scale (F-MPS).

Perfectionism has been identified as a common concern among clients who seek counseling services. For more than 20 years, the Frost Multidimensional Perfectionism Scale (F-MPS) has been used extensively to measure the construct of individuals' perfectionism. The current study used reliability generalization to identify the average score reliability as well as variables explaining the variability of score reliability. Typical reliability across subscale scores ranged from .71 to.86 with the Doubt about Action subscale showing the least variability and the Organization subscale showing the most. In addition, sex, language, and standard deviation of the scale had statistically significant relations to reliability estimates.

siRNA-based targeting of antiapoptotic genes can reverse chemoresistance in P-glycoprotein expressing chondrosarcoma cells.

BACKGROUND: High expression of P-glycoprotein is one of the well-known mechanisms of chemoresistance in chondrosarcomas. However, the role of antiapoptotic proteins, a common mechanism responsible for chemoresistance in other tumors, has not been well studied in chondrosarcomas. We examined the importance of P-glycoprotein and antiapoptotic proteins in the chemoresistance to doxorubicin of two Grade II chondrosarcoma cell lines, JJ012 and SW1353. RESULTS: We confirmed that both chondrosarcoma cell types expressed P-glycoprotein and antiapoptotic proteins (Bcl-2, Bcl-xL and XIAP). siRNA knockdown as well as pharmacologic inhibitors of cell survival proteins (Bcl-2, Bcl-xL and XIAP) enhanced apoptosis of chemoresistant chondrosarcoma cells by up to 5.5 fold at 0.1 micromol and 5.5 fold at 1 micromol doxorubicin. These chemosensitizing effects were comparable to those of P-glycoprotein inhibition by siRNA or pharmacologic inhibitor. CONCLUSION: These findings suggest that antiapoptotic proteins play a significant role in the chemoresistance of chondrosarcoma cells independent of P-glycoprotein. Based on the results, a new siRNA-based therapeutic strategy targeting antiapoptotic genes can be designed to overcome the chemoresistance of chondrosarcomas which is often conferred by P-glycoprotein.
