  • This research is to evaluate the arousal level by using cardiovascular response. PPG was used in this study as one of the method of measuring it rather than ECG (Electrocardiography) for the purpose of solving ergonomic problem of sensing. The participants were in the age group of 20 (mean=24, standard deviation=1.25): five men and five women. Each experiment composed with four identical sets. First, a black screen was displayed for 30 second rest. Then, the prepared 6 pair images were randomly presented for 10 second stimulation and for 30 second non-stimulation. PPG was measured on the earlobes of experimenters at 200Hz sampling frequency. PPG amplitude, PPI(Pulse to Pulse Interval), and PRV(Pulse Rate Variability) were analyzed according to arousal level. T-test was performed to compare between the PPG variables of rest and relaxation, rest and arousal, and relaxation and arousal. Relative to the rest state, PPG amplitude decreased in relaxed state and increased in aroused state. Relative to the rest state, PPI decreased in both emotional states. However, more significant decline was observed in aroused state. PRV's LF and HF were used in the form of LF/HF to compare between the relaxed and the aroused state. Therefore, PPG signal showed significant differences between relaxed and aroused state. In conclusion, evaluation of human arousal level used in the PPG analysis demonstrated that PPG has better usability and comforter measurement than ECG and is clearly an alternative method of measuring arousal level.

  • This study investigated the uncertainty, regret experience, and negative behavior intention of fashion consumers according to the types of internet shopping malls. The data was obtained from internet fashion consumers, and 394 responses were used in the data analysis. The statistical analysis methods were frequency analysis, factor analysis, reliability analysis, t-test, ANOVA, and regression analysis. As results, the uncertainty of internet fashion consumers was composed of two factors; information uncertainty and preference uncertainty. The regret experience was composed of function or service regret, suitability regret, and product regret. Also, the negative behavior intention was composed of purchase switching intention and purchase deferral intention. The information uncertainty of fashion consumers positively affected the negative behavior intention in all types of internet shopping malls (e.g., open market, integrated shopping mall, and fashion specialized shopping mall). In open market, the preference uncertainty negatively affected the purchase switching intention; however, the preference uncertainty positively affected the purchase deferral intention. In open market and fashion specialized shopping mall, the product regret of internet fashion consumers positively affected the negative behavior intention. In addition, there were partially significant differences in the factors of uncertainty, regret experience, and negative behavior intention by gender and marital status of demographic characteristics. The results of this study will provide useful information to the marketing strategies considering fashion consumer's negative emotion and behaviors according to the types of internet shopping malls.

  • Objectives: S-HTP is a projective test of cognitive activity. The purpose of this study was to examine the response characteristics in the S-HTP test as they related to seven emotions and cognitive processes. Methods: 153 students underwent S-HTP testing. 10 students were excluded and a total of 143 students' data was used for the study. 143 students were classified into four groups by SCAT. A survey was conducted on seven emotions and cognitive processes painting the Whole picture, house, tree, and person, and after receiving IRB review exemption, the chi-square test was conducted to check homogeneity of the groups by gender and age. Finally, frequency analysis by constitution for each item was conducted. Results: The reaction characteristics of S-HTP, focusing on the seven emotions and cognitive processes detailed by Korean Medicine, are as follows: 1. The primary sentiment while drawing during S-HTP was 'Joy (hui)' followed by 'Thought (sah)'. 2. The sentiments while painting during the S-HTP test, and the emotions of looking at the picture after the S-HTP test, increased in 'Joy (hui)' and decreased in 'Thought (sah)'. 3. 'Thought (Sah)' was the highest scored process while drawing S-HTP, followed by 'jee (智)'. However, 'ryeo (慮)' was similar to 'jee (智)' in an unclassifiable constitution. Conclusions: The primary characteristics of the S-HTP test response are 'Joy (hui)' and 'Thought (sah)' in emotion, and 'sah (思)' and 'jee (智)' in cognitive processes. Therefore, it is necessary to verify this during the S-HTP test.

  • Purpose: The purpose of this study was to identify influencing factors on vision-related quality of life in patients with retinal diseases receiving intravitreal injections by examining relationships among anxiety, depression, coping, eye health behaviors and vision-related quality of life. Methods: One hundred and five outpatients who were diagnosed with macular degeneration and diabetic retinopathy were recruited from one university hospital during August 16, 2019 to March 25, 2020. Data were analyzed using descriptive statistics (frequency and percentage, mean, standard deviation), and t-tests, ANOVA, Scheffé test, Pearson's correlations, and stepwise multiple regressions using the IBM SPSS Statistics 25.0. Results: The vision-related quality of life according to general characteristics of retinal disease patients with intravitreal injection showed significant differences in age (F=3.01, p=.034), subjective economic status (F=5.83, p=.004), types of retinal disease (t=2.62, p=.010), and disease in both eyes (t=-3.04, p=.003). The vision-related quality of life showed a significant positive correlation with age (r=.24, p=.012), and negative correlations with anxiety (r=-.66, p<.001), depression (r=-.48, p<.001), and emotion-focused coping (r=-.20, p=.036). The hierarchical regression analysis indicated that factors affecting vision-related quality of life in patients with retinal diseases were anxiety and subjective economic status, accounting for 47.0% of the variances of the vision-related quality of life. Conclusion: Based on our results, health professionals need to pay attention to patients with low socioeconomic status due to frequent treatments. Also, a program needs to be developed to decrease anxiety for outpatients receiving intravitreal injections to improve their vision-related quality of life.

  • Purpose: Adolescents use emoticons to express their emotions in an online environment. Hence, medical experts can understand the emotions of adolescents by emoticons. The goal of this study was to investigate the relationship between various emotions and emoticons among the Korean adolescents. Methods: The questionnaire survey was conducted between September 1 and 30, 2014, involving 3,272 students in elementary schools, middle schools, and high schools affiliated in the Department of Education of the metropolitan city of Busan. A total of 1,717 students responded to the survey. The participants consisted of 806 males (46.9%), and 911 females (53.1%). Among these, there were 557 elementary school students (32.4%), 617 middle school students (35.9%), and 543 high school students (31.6%). A social networking analysis was conducted using NodeXL. Results: The frequency of emoticon use among adolescents runs in the order of joy, sadness, fear, surprise, anger, disgust, and then depression. Elementary school females mainly use emoticons to express joy; middle school females use emoticons to express sadness, surprise, anger, disgust, and depression; and high school females use emoticons to express fear. Age- and gender-specific emoticon networks were visualized by using the Haren-Korel fast multiscale algorithm. Commonly used emoticons by age and gender were expressed in the networks. Results of age- and gender-specific emoticon networks visualization show similar results of centrality of seven emoticons. Conclusion: In the digital communication environment, emoticons could be used to catch the emotions of adolescents in Korea.

  • The purpose of this study is to examine the intergenerational transmission of mother-daughter attachment across three generations, and to determine whether the mother-daughter attachment of three generations influences the adult daughter's ego-resilience. The subjects of this study were 310 unmarried adult women aged 20${\sim}$29, residing in the Busan area, and their 310 middle-aged mothers. The mothers responded to two sets of questionnaire investigating their attachment to their mothers (G1-G2) in the past and the present attachment to their adult daughters (G2-G3). Meanwhile, the adult daughters were given questionnaires regarding their attachment to their mothers and their ego-resiliency. The measurements used for this study were the Inventory of Parent and Peer Attachment (IPPA) and the Ego-Resiliency Scale (ER). Among the distributed questionnaires, 265 sets were collected and 252 sets were actually analyzed using SPSS 12.0 after 13 sets had been excluded due to incomplete data. Basic statistics were used such as frequency analysis, Pearson's correlation and hierarchical regression analysis. The study results were as follows. First, the adult daughter-mother (G2-G3) attachment was explained mostly by mother-grandmother (G1-G2) attachment, daughter's age, and economic status of the family. The strongest factor was the mother-grandmother attachment which implies the transmission of attachment through generations. Second, among the factors that influenced the ego-resilience of an unmarried adult daughter, attachment to one's mother perceived by the daughter turned out to be the most significant. Especially, the more positive the adult daughter's emotion toward her mother and the higher the daughter's education, the stronger the ego-resilience of the adult single daughter was. It was concluded that the mother-daughter attachment remained consistent throughout three generations, which influenced the social-psychological adjustment of the adult unmarried daughter.

  • Purpose: This descriptive study aimed to investigate heart rate variability (HRV) according to sex and to elucidate the influence of negative emotion such as levels of stress, anxiety and depression on HRV among Korean college students based on a neurovisceral integration model. Methods: A descriptive study design was used. Eighty-six healthy college students participated in the study. Resting HRV and standing HRV on orthostatic stimulation were measured for 5 minutes during 4-6 p.m. in the afternoon. Levels of stress, anxiety and depression were assessed using the Global assessment of recent stress, State-Trait Anxiety Inventory and Beck Depression Index, respectively. Results: Out of the 86 students, 47 (54.7%) were men and 39 (45.3%) were women. Root mean square of the differences between adjacent RR intervals (RMSSD) and normalized high frequency (nHF) on standing HRV were significantly lower in men than in women (p= .005, p= .019, respectively). Male gender (β= 0.30, p= .013), higher level of stress (β= -0.36, p= .009) and lower level of depression (β = 0.30, p= .044) exerted a significant influence on decreased nHF in the multiple regression analysis. Conclusion: We suggest that men are more vulnerable to having reduced vagal activity on HRV than women. Since male gender, higher level of stress and lower level of depression level influenced decreased vagal activity, strategies are needed to improve stress and depression rather than anxiety especially for men, which contribute to promoting HRV to prevent cardiac health diseases.

  • This study mainly focuses on the dissatisfaction of the post-purchase behavior regarding the consumer dissatisfaction complaining behavior and repurchase intention In the literature study approach it was hypothe-sized that dissatisfaction variables was consisted of the cognitive process and emotion. And the dissatisfaction variables and the individual vari-ables and situational variables were set up to contribute to form the complaining behavior. In the process of the complaining behavior the first thing the consumers would do when they would seek for redress or not. Consumers who sought redress and actually received the fair treatment from a store practiced positive word-of-mouth. However consumers who received unfair treat-ment practived negative word-of-mouth exit behavior or the third party complaining Behavior. And consumers who did not seek any redress either showed exit behavior practiced negative word-of-mouth or no complaining behavior at all. Therefore. complaining behavior process consists of redress seeking process and non-redress seeking process. For the empirical study the survey method was used and two other researches were previously conducted. First of all the research was designed to comprehend consumer complaining behaviors process Secondly it was conducted for measuring validity and reliability: Cronbach's q. The sqmple was 569 women aged 2-'s to 5-'s living in Seoul and other suburban areas. The various methods were used to analyze the date such as frequency, percentage and multiple regression analysis. Overall the results were verified. 1) The dissatisfaction variables and individual variables influenced situational variables. 2) The complaining behavior intention was affected by dissatisfaction variables indivi-dual variables and situational variables. 3) The repurchase intention occurred more when the justice was performed Consequently the complaining behavior proce-dure was consisted of the redress seeking and non-redress seeking. And dissatisfaction vari-ables and individual variables were verified to influnce situational variables. These complaining behavior variables affected complaining behavior Especially in a case of redress seeking process complaining behavior and repurchase rate were highly affected by the perceived justice from a store.
