Today the u-government services are becoming more personalized and intelligent. For the successful implementation of personalization, individual user's privacy concerns must be respected and taken care of. Based on the empirical survey results, this research summarizes the reluctance to the government's use of private information using six categories. We measure user's psychological distance toward e-government using the four levels, adopting the suggestions by the Proxemics. Since a positive correlation is Identified between people's psychological Intimacy toward e-government and their tolerance to the use of private Information, the amount and/or types of private information should be sequentially used in personalization systems. Initially allowing the least intolerable private information such as occupation information, the personalization system should additionally use the next tolerable Information such as health information or service request/interest information, as user's psychological distance toward government services becomes shorter.

Background: Myofascial pain dysfunction syndrome (MPDS), otherwise called myofascial pain is one of the most common temporomandibular disorders, which in turn is the most common cause of orofacial pain of non-dental origin. Its etiology is multifactorial and still poorly understood. Psychological factors have been shown to play a role in the etiology. The aim of the study was to evaluate the association between anxiety and salivary cortisol levels in patients with myofascial pain. Methods: Twenty patients suffering from myofascial pain were recruited as the study group. The same number of age and sex matched healthy individuals were taken as the control group. The salivary samples collected between 9-9:15 am from both groups were analyzed for cortisol levels with the competitive enzyme-linked immunosorbent assay method. Anxiety levels of 40 patients were measured using Hamilton's anxiety scale. Results: The mean serum cortisol level of the MPDS group showed a highly significant difference (P < 0.001) from the controls. The mean anxiety scores of the MPDS group showed a highly significant difference (P < 0.001) from the controls. A positive correlation was found between anxiety and the salivary cortisol levels in MPDS patients. Conclusions: These findings suggest that anxiety plays a vital role in the etio-pathogenesis of MPDS; thus, besides pharmacological treatment, psychological support is also needed.

Since 1998 when economic assistance from IMF started, the empirical research on the effects of unemployment and drastic income loss on psychological functioning among the unemployed as well as their family members has increased. These studies have found that unemployment and drastic income loss following unemployment have significant negative influence on the psychological outcomes such as anxiety and depression of the unemployed and their family members. Studies have also focused on the role of social support in this process, and reported that depending on the levels of received social support, unemployment and income loss have differential effects on the psychological aspects of the unemployed. However, these studies have several weaknesses. First, most of the related studies employed the data which were collected from limited regions of the country, which imposes limitations on the scope of the generalizability of research findings. Second, the main independent variables used in these studies were mainly unemployment or income loss, which ignore the psychological evaluation by the employed of their family financial situations. Third, in analyzing the moderating effects of social support, most studies have focused mainly on showing the existence of moderating effects by social support. Consequently, the nature and role of social support remained unanalyzed and left to speculations. The purpose, of this study is to examine the effects of economic pressure experienced by family heads who were unemployed and to analyze the moderating role of social support based on a nationally representative sample. The findings showed that economic pressure has negative influence on anxiety and depressive feelings among the unemployed, and that the effect of economic pressure on depressive feelings were substantially higher among those who have received lower levels of social support from family members than that among those with higher levels of family support.

The purposes of the study is to classify the psychological characteristics of gamblers using by latent profile analysis and to identify the consequences according toof the latent profiles. The subjects of the study are 473 adults gamblers who responded to a online survey about gambling patterns, basic psychological needs(BPNs), and mental health status(MHS) such as stress, depression, and anxiety. Using latent profile analysis known as the person-centered analysis, the results showed that psychological characteristics of gamblers were classified into three groups: 'Lower MHS-BPNs', 'Middle MHS-BPNs', and 'Upper MHS-BPNs'. Also, the as outcome variable, levels of problematic gambling(KCPGI) showed significant differences across the latent profiles such as Problem gambling(M=11.393) on 'Lower MHS-BPNs', Moderate-risk gambling(M=4.277) on 'Middle MHS-BPNs' and Low-risk gambling (M=1.718) on 'Upper MHS-BPNs'. Overcoming the limitations of variable-centered analysis in the existing studies, this study providesreveals new insights onin the psychological characteristics of gamblers and how different latent profiles of gamblers may be in theirdistinct levels of problematic gambling. Finally, limitations of the study and future directions for research on gambling problems are discussed.

This study of elderly in-patient subjects' expected level of care given by family members and nurses is intended to provide foundational information for use by nurses is attending to elderly patients. The objects of the study were elderly in-patients over the age of 65 hospitalized at two General hospitals in Chonju: 102 subjects filled out the 60 question survey between December 16 and 24. 1996. The analysis process was conducted using SPSS producing percentage. mean and standard deviation. maximum and minimum values. t-test, ANOVA. and so on. The results are as follows: 1. From the general results of the survey. one can observe that statistically significant differences appeared in various levels of education of the subjects: no education(2.98). primary school completed(2.91). middle school or higher completed(2.77). As shown. the lower level of education correlates with higher care-giving expectation. 2. On a scale of 1(minimum) to 4(maximum). the mean levels of care expected by elderly inpatients from their families is 2.93. with a standard deviation of 0.28. The level of psychological care expected(mean 3.02. standard deviation 0.31) is higher than the level of care expected(mean 2.83. standard deviation 0.34). 3. The level of care expected among those of different levels of dependency for daily living (differentiated as dependent. partially dependent. independent) was highest among the partially dependent(mean 2.98. standard deviation 0.17). but the results were not statistically significant. 4. Elderly in-patients with high levels of emotive interaction with their families expected relatively high levels of physical care. while the highest levels of socio-psychological care were expected from those who reported normal levels of emotive interaction with their families. However. We can see that low levels of care are expected from those reporting low levels of emotive interaction with their families. Overall. the differences in the level of care expected between those reporting different levels of emotive interaction with their families was not shown to be statistically significant.

This study examined the effects of parental psychological control, dysfunctional perfectionism, and self-conscious emotions on depression in adolescents. The sample consisted of 471 adolescents (212 boys, 259 girls) attending high schools in Seoul. The results from Structural Equation Modeling indicated that dysfunctional perfectionism and self-conscious emotions mediated the impact of parental psychological control on depression only in the mother-daughter relationship, such that with mothers' greater psychological control, girls experienced higher levels of dysfunctional perfectionism and self-conscious emotions, and reported higher depression scores. Similarly, dysfunctional perfectionism functioned as a mediator in the association between parental psychological control and adolescent depression. This tends to support findings from previous studies emphasizing the importance of same sex parent-adolescent relationships. Dysfunctional perfectionism also had the largest direct effect of all variables analyzed on depression. Parental psychological control did not show statistically significant effects on self-conscious emotions for either boys or girls. These findings suggest that interventions designed to promote adolescents' mental well-being should focus on parenting of the same sex parent as well as adolescent cognitive characteristics.

Occupants' visual perception, psychological responses and spatial satisfaction under various indoor lighting environments were analyzed in this study. Field measurements and surveys were conducted in four coffeeshop space where different lighting conditions were used. Results imply that worse visual comfort was reported under direct lighting conditions that exposed light sources to occupants. To improve spatial satisfaction in space, lighting environments should lessen visual thresholds and distraction. Also, necessary illuminance levels should be kept with appropriate color of light that occupants prefer. Worse spatial satisfaction was reported under direct lighting environments, and spatial satisfaction was strongly relevant to visual comfort. Psychological comfort for space was positive in space where visual thresholds were minimized and visual comfort was positively evaluated. Psychological and spatial satisfaction was relevant each other. Occupants preferred to stay longer in space where psychological and spatial satisfaction was positively achieved due to less visual thresholds and improved visual comfort. Better psychological and spatial satisfaction was achieved in space where temporary mood and visual perception were favorably evaluated under indirect lighting environments.

This study aimed to examine the effect of parental psychological control on adolescents' non-suicidal self-injury and verify whether this effect is mediated by depression. In the first survey of 647 middle and high school students, only those who had experiences of non-suicidal self-injury were selected (136 adolescents). For data analysis purposes, descriptive statistics for each measured variable and Pearson's correlation coefficients among research variables were calculated. In addition, Process Macro - Model 4 by Hayes (2013) was used to investigate the mediating model. Finally, the bootstrapping method was applied to confirm the significance of the mediating effect. The results of this study were as follows. First, parental psychological control and depression directly affected the frequency of non-suicidal self-injury among adolescents. Second, depression mediated the relationship between parental psychological control and non-suicidal self-injury. In conclusion, the more parents controlled their children's psychological factors, the higher the level of depression among adolescents, and as a result, the higher the frequency of non-suicidal self-injury. These findings suggest that educational intervention on parental psychological control is important to prevent and reduce non-suicidal self-injury; however, psychotherapy intervention that reduces the levels of depression should also be required.

Objectives: To investigate the association between psychological distress and obesity among law enforcement officers (LEOs) in the United States. Methods: Self-reported data on psychological distress based on six key questions were obtained from LEOs who participated in the National Health Interview Survey (2004-2010). We used Prochaska's cut-point of a Kessler 6 score ${\geq}5$ for moderate/high mental distress in our analysis. Mean levels of body mass index (BMI) were compared across three levels of psychological distress. Results: The average age of LEOs (n = 929) was 39.3 years; 25% were female. Overall, 8.1% of LEOs had moderate or high psychological distress; 37.5% were obese (BMI ${\geq}30$). Mean BMI increased with increasing psychological distress (no distress, BMI = $27.2kg/m^2$; mild distress, $27.6kg/m^2$; and moderate/high distress, $33.1kg/m^2$; p = 0.016) after adjustment for age, race, income, and education level among female officers only. Physical activity modified the association between psychological distress and BMI but only among male LEOs (interaction p = 0.002). Among male LEOs reporting low physical activity, psychological distress was positively associated with BMI ($30.3kg/m^2$ for no distress, 30.7 for mild distress, 31.8 for moderate/high distress; p = 0.179) after adjustment, but not significantly. This association was not significant among males reporting high physical activity. Conclusion: Mean BMI significantly increased as psychological distress increased among female LEOs. A longitudinal study design may reveal the directionality of this association as well as the potential role that physical activity might play in this association.
