Nowadays, as we can notice on social media, most users choose to use more than one language in their online postings. Thus, social media analytics needs reviewing as code-switching analytics instead of traditional analytics. This paper aims to present evidence comparable to the accuracy of code-switching analytics techniques in analysing the mood state of social media users. We conducted a systematic literature review (SLR) to study the social media analytics that examined the effectiveness of code-switching analytics techniques. One primary question and three sub-questions have been raised for this purpose. The study investigates the computational models used to detect and measures emotional well-being. The study primarily focuses on online postings text, including the extended text analysis, analysing and predicting using past experiences, and classifying the mood upon analysis. We used thirty-two (32) papers for our evidence synthesis and identified four main task classifications that can be used potentially in code-switching analytics. The tasks include determining analytics algorithms, classification techniques, mood classes, and analytics flow. Results showed that CNN-BiLSTM was the machine learning algorithm that affected code-switching analytics accuracy the most with 83.21%. In addition, the analytics accuracy when using the code-mixing emotion corpus could enhance by about 20% compared to when performing with one language. Our meta-analyses showed that code-mixing emotion corpus was effective in improving the mood analytics accuracy level. This SLR result has pointed to two apparent gaps in the research field: i) lack of studies that focus on Malay-English code-mixing analytics and ii) lack of studies investigating various mood classes via the code-mixing approach.

Purpose: This study investigated changes in psychological and physiological indices in cancer survivors who participated in a forest therapy camp in Korea. Methods: A total of 37 cancer survivors (19 and 18 in the experimental and control groups, respectively) participated in this study. Over a 2-night and 3-day period, the participants in the experimental group took part in a forest therapy camp that included activities such as gymnastics, walking, five-senses experiences, and meditation. Both groups completed self-report questionnaires that measured their stress levels and profile of mood states, both before and after the forest therapy camp. Blood samples were collected to measure the levels of cortisol, serotonin, and natural killer (NK) cells. Results: After the forest therapy camp, the experimental group exhibited reduced stress levels (p = .031) and a significant improvement in total mood disturbance (p = . 047) when compared with the control group. The level of serotonin also significantly increased (p < .001). However, in contrast to the prediction, a significant increase in cortisol was noted in the experimental group relative to the control group (p = .016). Moreover, no significant difference in NK cells was noted between the two groups. Conclusion: Forest therapy can be easily applied to cancer survivors. The positive psychological effects of the forest therapy camp were confirmed by improvements in stress and mood states and the increased level of serotonin in forest therapy camp participants. However, there is a need for a follow-up evaluation of cortisol and NK cells due to the absence of significant between-group differences.

The purpose of this study was to explore the effect of maternal perception of children's temperament on parenting stress. The subjects of this study were 303 mothers of four to six-year-old. Evaluations of Parent and Teacher temperament questionnaire for Children 3-7 years of age(Tomas, Chess, & Kom, 1977)(korean version) was used to measure children's temperament, and PDH(Parenting Daily Hassles) was used to measure maternal perception of parenting stress. Data were analyzed by descriptive analysis, t-test, ANOVA, Peasons's Correlation and multiple regression analysis and Duncan test for post test by SPSS WIN program. The results of this study were as follows; First, the average level of maternal perception of children's temperament was the highest in the category of adaptability and the lowest in the category of threshold of responsiveness. Second, maternal perception of children's temperament was significantly different according to children's sex. Boys were perceived higher than girls for the category of activity level. Third, the degree of daily hassles was explained by adaptability, the quality of mood, and activity level relatively, while the intensity of parenting stress could be predicted orderly by adaptability, threshold of responsiveness, attention span & persistence, regularity, and activity level. Fourth, mother's daily hassles was explained 22% valiance by children's temperament such as adaptability, the quality of mood, and activity level. Future research should be done to identify the interaction of temperamental factors.

This study compared the effect of different types of sounds(no sounds, sounds of nature, music, and sounds of children playing) on profile of mood states(POMS) in a healing forest. Data were collected from 231 respondents selected from among visitors to the 'Healing Field' in 'Jangseong Chukryongsan Pyeonbaek Healing Forest' in October, 2012. Each respondent was exposed to one type of sound. The results showed that there were differences in POMS among the different sound treatment groups. Sounds of children playing showed negative effects on POMS. Unexpectedly, however, sounds of nature and musical sounds had no effects on POMS. These tendencies were consistently found not only for total mood disturbance score (TMDS) but also for POMS by factors (i. e. tension, anger, vigor, fatigue, confusion, depression). Perceived crowding level was positively correlated with TMDS(r=0.568) and POMS by factors (range: r=0.331 - 0.571). This paper discusses the research results and suggests several managerial implications.

Background: This study investigated the longitudinal associations between the degrees of positive and negative spillover in work-life balance (WLB) at baseline and reports of depressive mood at a 2-year follow-up in Korean women employees. Methods: We used a panel study design data of 1386 women employees who participated in the Korean Longitudinal Survey of Women and Families in both 2014 and 2016. Depressive mood was measured using the "10-item Center for Epidemiologic Studies Depression Scale." Associations between the positive and negative spillover in WLB at baseline and reports of new incidence of depressive mood at 2-year follow-up were explored using a multivariate logistic regression model. Results: Negative spillover in WLB at baseline showed a significant linear association with reports of depressive mood at 2-yearfollow-up after adjusting for age, education level, marital status, number of children, and positive spillover (P = 0.014). The highest scoring group in negative spillover (fourth quartile) showed a significant higher odds ratio of 1.95 compared with the lowest scoring group (first quartile; P = 0.036). Conclusion: Positive spillover in WLB showed a U-shaped association with depression. The degrees of positive and negative spillover in WLB among Korean women employees at baseline were associated with new incidence of depressive mood within 2 years. To prevent depression of female workers, more discrete and differentiated policies on how to maintain healthy WLB are required.

The purposes of this study were to identify the stress level of nursing students prior to clinical training and to examine the effects of aromatherapy on stress, stress perception, and mood during clinical practice. This study was a randomized control trial using a pre-post test conducted from May-July 2016. A total of 41 junior nursing students were recruited. The experimental group (n=22) underwent aroma inhalation using a necklace containing lavender essential oil and a control group (n=19) used a normal saline necklace. There were significant improvements in stress (p=.023) and mood levels in the experimental group (p=.006). The difference in stress perception between the experimental and control groups was not statistically significant (p=.382). Aroma therapy might be useful for decreasing stress and improving their positive mood during clinical practice for nursing students.

Objectives : Thyroid function is associated with psychiatric disturbance such as mood symptoms, cognitive functions, anxiety and sleep problem. We evaluate the effects of thyroid dysfunction on negative symptoms of schizophrenia, mood symptoms and somatic symptoms in patients with schizophrenia. Methods : Sixty five patients with schizophrenia were recruited. The patients were classified into two groups; the patients with the history of abnormal thyroid indices level(group of abnormal thyroid function) and the patients without the history of normal thyroid indices level(group of normal thyroid function). At baseline and 8 weeks later, psychiatric symptoms were assessed with the Scale for the Assessment of Negative Symptoms (SANS), the Scale for the Assessment of Positive Symptoms(SAPS), and Beck Depression Inventory(BDI), Somatosensory Amplication Scale(SSAS). Results : During 8 weeks, there were significant differences in the changes of SANS, BDI, SSAS between group of abnormal thyroid function and group of normal thyroid function. Compared to group of normal thyroid function, group of abnormal thyroid function showed greater reduction of the scores of SANS(23.3%), BDI (19.6%), and SSAS(16.2%), respectively. However, there was no significant correlation between the scores of SANS, BDI, and SSAS. Conclusion : Our study suggested that abnormal thyroid indices would predict the prognosis of negative symptoms, mood symptoms, and somatic symtpoms in patients with schizophrenia.

The primary aim of this study was to examine how various factors influence university students' intention to use ChatGPT for educational purposes and to analyze the structural relationships between these factors. Specifically, the study investigated Social Mood and Self-Efficacy as exogenous variables, while considering Confirmation, Task Technology Fit, and Satisfaction as mediating variables, and Intention to Use as the dependent variable. Data were collected from 261 students at two universities in the Seoul metropolitan area of South Korea, and structural equation modeling was employed to analyze the impact of each variable on the Intention to Use and the interrelationships among the variables. The study found that ChatGPT partially meets the educational expectations of Korean university students. It was observed that Confirmation, which is influenced by Social Mood and Self-Efficacy, significantly affects the intention to use ChatGPT. Additionally, Satisfaction has a direct and significant influence on students' intention to use ChatGPT, indicating that the level of satisfaction with ChatGPT plays a crucial role in their continued usage. Moreover, Social Mood and Self-Efficacy were found to indirectly influence the intention to use ChatGPT through mediators such as Confirmation, Task Technology Fit, and Satisfaction. These findings highlight the complex interplay between these variables and their impact on students' usage of ChatGPT, providing valuable insights into the factors that drive its educational use.
