This study was conducted to examine whether hasty behaviors were structurally maintained even after the expansion of age zones and to determine the characteristics of hasty behaviors by gender and age. To this end, an analysis was made of the data of 591 respondents after excluding the insincere respondents from the 602 adults who had replied to the survey on hasty behaviors. Its results showed that a hasty behavior consisted of 5 factors regardless of age. Even when age was expanded, a hasty behavior maintained its structural stability. On the other hand, women were higher than men in the average score of hasty behaviors. Lastly, hasty behaviors decreased with the increase in age. The gender differences in hasty behaviors were analyzed on the basis of those in time pressure perception and task processing method. They were presented to show that the speed reduction by age increase is related to psychological mechanism as well as bodily function.

BACKGROUND/OBJECTIVES: Emotional eating is one of the eating behaviors in which negative emotions affect eating. During the luteal phase, premenstrual syndrome (PMS) and its associated psychological and physical symptoms can appear in some women, and a few of them suffer from premenstrual dysphoric disorder (PMDD), a severe form of PMS. Some women diagnosed with PMS/PMDD experience emotional eating during the luteal phase, which may be a coping mechanism for psychological stress. This study aimed to investigate how PMS/PMDD and negatively perceived stress are related to emotional eating. SUBJECTS/METHODS: A total of 409 women aged 20 to 39 yrs with a body mass index (BMI) ranging from 18.5 to 29.9 kg/m² participated in this study. Participants who responded to all the questions of the Shortened Premenstrual Assessment Form, Negative Perceived Stress Scale, and Emotional Eater Questionnaire were divided into a PMDD and a non-PMDD group according to the cut-off value for PMDD diagnosis. Independent t-tests and mediation analyses were performed to compare the 2 groups. RESULTS: No significant differences between the 2 groups were found in terms of BMI; however, the average values for emotional eating, PMS, and negative perceived stress of the PMDD group were significantly higher than those of the non-PMDD group. Only negative perceived stress had a significant effect on emotional eating in the non-PMDD group. In the PMDD group, PMS was statistically significant for both negative perceived stress and emotional eating mediated by negative perceived stress. Consequently, it appeared to have a partial or complete mediation depending on the independent variable for the PMDD group. CONCLUSIONS: This study highlights the importance of managing negative perceived stress to control emotional eating in PMS/PMDD for improved women's health.

The ultimate purpose of psychotherapy is to identify covert causes of a psychological problem and then to modify and change the causes. The goal of this study is also to make contribution to SNS addiction intervention program development through exploring the covert causes of SNS addiction which recently became social issue. Previous research identified such overt causes of SNS addiction as maladaptive self-concept (e.g., low self-esteem), maladaptive personality (e.g., strong narcissism) and strong negative emotions (e.g., high level of anxiety). Based on previous research, the study explored early maladaptive schema (i.e., cognitive dimension) and emotion dysregulation (i.e., emotional dimension) as the covert causes of SNS addiction and conceptually developed psychological maladaptive mechanism of 'early maladaptive schema ${\rightarrow}$ emotion dysregulation ${\rightarrow}$ SNS addiction.' As a result of a survey with respondents in their 20's who are at high risk for SNS addiction, the mechanism was confirmed for females. However, a significant relationship of 'early maladaptive schema ${\rightarrow}$ SNS addiction' was found for males. The findings offer an implication that interventions of early maladaptive schema for males and females in their 20's and interventions of emotion dysregulation for females in their 20's can fundamentally help cure their SNS addiction.

The mechanism of emotion is complex and influenced by a variety of factors, so that it is crucial to analyze emotion in broad and diversified perspectives. In this study, we classified neutral and negative emotions(sadness, fear, surprise) using arousal evaluation, which is one of the psychological evaluation scales, as well as physiological signals. We have not only revealed the difference between physiological signals coupled to the emotions, but also assessed how accurate these emotions can be classified by our emotional recognizer based on neural network algorithm. A total of 146 participants(mean age $20.1{\pm}4.0$, male 41%) were emotionally stimulated while their physiological signals of the electrocardiogram, blood flow, and dermal activity were recorded. In addition, the participants evaluated their psychological states on the emotional rating scale in response to the emotional stimuli. Heart rate(HR), standard deviation(SDNN), blood flow(BVP), pulse wave transmission time(PTT), skin conduction level(SCL) and skin conduction response(SCR) were calculated before and after the emotional stimulation. As a result, the difference between physiological responses was verified corresponding to the emotions, and the highest emotion classification performance of 86.9% was obtained using the combined analysis of arousal and physiological features. This study suggests that negative emotion can be categorized by psychological and physiological evaluation along with the application of machine learning algorithm, which can contribute to the science and technology of detecting human emotion.

This study examined what factors were associated with psychological well-being of grandparents providing daily care to their grandchildren. More focus on the role of various mediators such as caregiving perception and resources were given to investigate the complicated relationships between providing care and psychological function. I used the nationally representative data from the '2008 Korean National Survey of Welfare Need in the Elderly'. Results showed that there were diverse circumstances of caregiving. Grandparents who cared their grandchildren on behalf of dual career parents emerged predominantly from them. Findings also suggested that type of caregiving was related to external factors. Grandparents shouldering greater responsibility for their grandchildren showed lower levels of resources such as financial conditions and social support, and more negative perception of caregiving, which in turn was associated with lower psychological well-being. Finally, more financial resource and neighborhood support directly influenced more positive perception of caregiving. To enhance resources and empower grandparents raising their grandchildren, community-based intervening mechanism incorporating various environments and effective services to meet the needs of grandparents should be discussed in future studies.

This study surveyed how retirees' evaluation of starting food service business affects the effectiveness their new business and quality of life, based on personal factors such as entrepreneurship and business-starting capability and environmental factors by using questionnaires. Bootstrapping was carried out in order to find out factors affecting rapidly changing new business environments and retirees' initial intent to start a business so as to verify basic hypothesis about relation between retirees' evaluation of starting food service business (social, economic, and psychological effects) and the effectiveness of their new business and quality of life and confirm whether the effectiveness of the new business acts as a medium between the evaluation of starting food service business and quality of life. In addition, PLS-MGA was performed in order to verify whether the correlations among test factors can be varied according to the kind of job the target retirees had. Having examined the basic thesis, it was found that social and economic factors had significant positive effect on the effectiveness of the new business, and social and psychological factors had significant positive effect on the quality of life. Having analyzed whether the effectiveness of new business acted as a media between evaluation of starting food service business and quality of life, there was no significant effect as a medium. Having studied whether the kind of job of the retirees controlled or affected the relations among evaluation of starting food service business, effectiveness of new business and quality of life, the results were as follows: in the office job retiree group, the greater economic factor led to increase of effectiveness of new business, while social and psychological factors influenced the quality of life; In the physical labor group, the higher social factor resulted in higher effectiveness of new business, which showed significant positive effect on the quality of life. Having researched about which element is considered to be most important in starting food service business, the most important element was found to be dish/menu, followed by staff management, accounting management, business management, and service education. Having analyzed relation between accomplishment and important consideration for starting food service business, "managers with entrepreneurship," "appropriate distribution of time to prepare for starting business," and "operation of practical field education programs" showed higher importance compared to the degree of satisfaction, so it is needed to more concentrate on the above matters. This study intends to raise retirees' awareness of starting business and help them live better life based on the analysis results, and further suggest detailed mechanism and specific operations of factors affecting retirees' decision making on starting business, such that they can use the information as basic materials to make better choices that can lead to successful business.

The present research investigated the psychological nature of low levels of trust in Korean society and the role of family expansionism, a cultural psychological factor, in this phenomenon. Specifically, we examined the possibility that Koreans' distrust toward social system is, at least partially, due to high standards for trust, which might be closely related to Koreans' cultural characteristic of family expansionism. In Study 1, the relations between levels of family expansionism, trust standards, and actual levels of trust for parents, judiciary, and politicians were examined among 540 Korean adults. In Study 2, we manipulated levels of family expansionism to examine its effect on trust standards. Results showed that trust standards were higher for politicians than parents. Participants' trust standards for politics were unrealistically high, especially on the responsibility factor. Actual levels of trust for judiciary and politicians were low when the trust standards for these targets relative to trust standards for parents were high. Moreover, the trust standards and levels of trust for judiciary and politicians (relative to those for parents) were positively correlated to levels of family expansionism. In other words, higher levels of family expansionism were linked to higher trust standards and levels of distrust for judiciary and politicians. In addition, Study 2 results showed that trust standards became high when family expansionism was induced. Unlike previous studies which focused on causes of low levels of trust while assuming that Korean society itself is a low trust society, the present research investigated the underlying mechanism behind the seemingly low trust in Korean society.

Background: The singing bowl is a bowl-shaped percussion instrument and is used in meditation and healing programs, but the mechanism of its clinical effects is unclear. Purpose: In this paper, we reviewed the peculiar acoustic property of the singing bowl sound and discussed on physical mechanisms of the clinical effects of the singing bowl sound. Methods: We studied the literature by reviewing it. Results: There are multiple pitches at adjacent frequencies in the singing bowl sound, and they give rise to the beat phenomenon. This results in a solid persisting beating felt in the singing bowl sound. Furthermore, the beat that depends on singing bowls and playing methods includes a rhythm often similar to the frequency band of brain waves (theta wave) observed in meditative states and induces a synchronization phenomenon in which the rhythm activates the brain waves in meditative states. Furthermore, we are to infer that the clinical effect of the singing bowl sound is closely associated with the synchronization of brain waves to the beat rhythm of the singing bowl sound. Conclusion: To clearly understand the clinical mechanism of the singing bowl sound, we suggest further systematic studies on the psychological and physiological responses to the beats of the singing bowl sound.

This study has been performed to explore verbal and behavioral expression of sexual desires among male elderly residents who have been living in long tenn care facilities. There are three topics covered in this study; first, in what situations and how seriously do care workers encounter expression of sexual desires of the elderly residents? Second, what kind of negative consequences do they believe those sexual behaviors will lead to? Third, how can we implement defensive measures against the sexual behaviors? In this study, twenty three care workers working full time in five retirement and care facilities were asked about their experience and perception of the above study agendas, and answers of the qualitative interview were drawn as follow; first, the elderly residents apparently show a variety of sexual harassment and provoking behaviors such as sticking to specific women, physically touching and attacking, and induce obscenely activities against female residents, care workers, and volunteer visitors. Second, their sexual behaviors are often influenced by their isolated and abandoned emotionality as well as living situation in rural areas. Third, their sexual behaviors often critically affect care work plan and facility managements by severely discouraging female care givers and community supporters. Therefore in this study, suggestions and defensive measures were made as follows: first, education and counselling programs toward female workers and volunteers need to be developed, and the programs should cover psychological and behavioral mechanism of sexuality in later life. Second, self control plans need to be empowered toward the elderly residents; in the plans, the elderly residents shall be encouraged to evaluate primary cause and proper solutions of sexual behaviors of their peering residents. Third, combination of healthy housing and care facilities for frail elderly need to be integrated in a neighboring location, so that when residents and workers encounter extreme episodes of sexuality of healthy residents in a housing facility, the problematic sexual residents are partially transferred into a neighboring care facility and thereafter other residents and cafe givers are relieved from stressful contacts with the extremely sexual residents.

This study has inferred the mechanism of psychological observation activities through comparison analysis of the observation data acquired from eye-tracking and their post-estimation. The results of their analysis can be summarized as the followings. First, even though the frame of analysis has been set up so that there might not be any change to the number of the sections even with any change of consecutive observation times, the fact that the time by area decreases along with the change of consecutive observation from three times to six and nine times means that the time spent on "recognition" of space information reduces in the course that the feature of observing for space information switches from "perception to recognition". Second, the subjects moves their eyes incessantly in order to acquire space information while observing the space, when it was confirmed that there was a difference between "the space which the subjects searched for information by means of observation activities" and "that which they thought they observed that remaining in their consciousness". The appreciation of this kind of difference is very significant for the analysis of observation features. Third, the short observation (0.1 second, three times of consecutive observations) is consistent with "Ares I, intensively searched = that marked as having been observed consciously" by 60%, while the long-time observation (0.3 second, 9 times of consecutive observations) had 56%, which was relatively high, of "Area I, searched intensively ${\neq}$ that marked as having been observed consciously", which means that the observation feature seen at the activities of "consciousness : unconsciousness" and "observation : search" had some change in the course of changing from "perception to recognition".
