PURPOSE: This study was conducted to examine the influencing factors of social support, self efficiency and depression among the hearing-impaired and physically disabled on their job stress. METHODS: The data were collected from Jan.1 to Aug. 30, 2010 from 151 disabled workers. The instruments for this study were the Korean Occupational Stress Scale (KOSS), Social Support Scale, General Self-Efficacy Scale and Beck Depression Inventory-Korean Version (K-BDI). The data were analyzed using t-test, Pearson correlation coefficient and multiple regression with the SPSS/WIN 18.0. RESULTS: The physically disabled show higher social support (t=0.284, p= .001) and self efficacy (t=0.165, p= .024) but lower in depression (t=0.789, p<.001) than the hearing-impaired. There are negative correlation between job stress and social support, job stress and self efficacy but a positive correlation between job stress and depression. These three factors explained 42.9% of the variance in job stress. CONCLUSION: Social support and self efficacy have positive impacts on job stress but depression has negative impact.

OBJECTIVES: The aims of this study are to test the applicability of the continuing hospitalization judgement guidelines of The Primary Mental Health Review Board and to provide the basic data for the development of valid guidelines. METHODS: The request sheets submitted to Cheongju Primary Mental Health Review Board for continuing hospitalization from April 2009 to July 2001 were reviewed. The results according to the guidelines were compared with board's final decision. The aim in making these comparison was to determine the factors affecting the board's decisions. RESULTS: Cheongju Primary Mental Health Review Board assessed 1223 requests during the period, and declined 65 of those requests. The sensitivity and specificity for dissent of the algorithm in the guidelines are 51.6% and 97.0%, respectively. The patterns of data in the sheets from the mental facilities were different from the psychiatric hospital or the clinic. The presence of a guidance's signature, mental status, and specialist's opinion could be factors affecting the board's decision. CONCLUSION: The result suggests that distinguished guidelines are needed for mental facilities. Social support systems and functional impairments may be meaningless because they did not affect the board's decision or could be replaced by other factors. The algorithm and judgement system should be revised to increase sensitivity for dissent. Further research is required concerning the development of standardized guidelines on the judgement for continuing hospitalization.

OBJECTIVES: Standardization of head size is essential for the volume study. Cortical thickness analyses are increasingly being used in many fields of neuroscience. However, it is not established whether head size correction should be done for thickness study. METHODS: Using the Open Access Series of Imaging Studies data, we determined cortical thickness of 316 cognitively normal participants aged 18-94 with FreeSurfer. The association between head size and cortical thickness of whole cortical mantle and in each lobe among age tertile groups was assessed. Estimated total intracranial volume (eTIV) was calculated for determining head size. RESULTS: Across all participants, cortical thickness in whole brain except some areas in cingulate and insula decreased with aging. eTIV had positive correlation with the thickness of frontal, parietal, occipital and whole brain areas. However, the age effect was not shown in whole brain of the first tertile group and in cingulate areas of the third tertile group. eTIV had negative correlation with the thickness of cingulate in the third tertile group. Gender effects were shown in some areas in third tertile group, but it would be due to difference of head size. CONCLUSIONS: These findings suggest that head size standardization might be done especially in older population and in studies of paralimbic areas.

OBJECTIVES: It is well known that problem drinking is associated with alterations of brain structures and functions. Brain functions related to alcohol consumption can be determined by the resting state functional connectivity in various resting state networks (RSNs). This study aims to ascertain the alcohol effect on the structures forming predetermined RSNs by assessing their cortical thickness. METHODS: Twenty-six abstinent male patients with alcohol dependence and the same number of age-matched healthy control were recruited from an inpatient mental hospital and community. All participants underwent a 3T MRI scan. Averaged cortical thickness of areas constituting 7 RSNs were determined by using FreeSurfer with Yeo atlas derived from cortical parcellation estimated by intrinsic functional connectivity. RESULTS: There were significant group differences of mean cortical thicknesses (Cohen's d, corrected p) in ventral attention (1.01, < 0.01), dorsal attention (0.93, 0.01), somatomotor (0.90, 0.01), and visual (0.88, 0.02) networks. We could not find significant group differences in the default mode network. There were also significant group differences of gray matter volumes corrected by head size across the all networks. However, there were no group differences of surface area in each network. CONCLUSIONS: There are differences in degree and pattern of structural recovery after abstinence across areas forming RSNs. Considering the previous observation that group differences of functional connectivity were significant only in networks related to taskpositive networks such as dorsal attention and cognitive control networks, we can explain recovery pattern of cognition and emotion related to the default mode network and the mechanisms for craving and relapse associated with task-positive networks.

Depression in the elderly population has shown increased likelihood of neurological disorders due to structural changes in the subcortical area. However, further investigation into depression related subcortical changes is needed due to mismatches in structural analysis results between studies as well as scarcities in research regarding subcortical connectivity patterns of subclinical depression populations. This study aims to investigate structural differences in subcortical regions of aged participants with subclinical depression using 3Tesla MRI. In structural analysis, volumes of each subcortical region were measured to observe the volumetric difference and asymmetry between groups, but no significant difference was found. In addition, fractional anisotropy (FA) and apparent diffusion coefficient (ADC) did not show any significant differences between groups.Structural analysis using probabilistic tractography indicated that the connection strength between left nucleus accumbens-right hippocampus, and right thalamus-right caudate was higher in the control group than the subclinical depression group. The differences in subcortical connection strength of subclinical depression groups, have shown to correlate with emotional and cognitive disorders, such as anxiety and memory impairment. We believe that the analysis of structural differences and cross-regional network measures in subcortical structures can help identify neurophysiological changes occurring in subclinical depression.

Background: This study explored the effect of anger on suicidality by dividing participants into a group with major depressive disorder (MDD) and a non-MDD group, and also investigated whether the anger expression affects suicidality in participants without clinical depression. Methods: A total of 1,015 residents responded to anonymous questionnaires in our survey. The survey included scales, such as the Patients Health Questionnaire-9 (PHQ-9), Korean State-Trait Anger Expression Inventory, and Mini-International Neuropsychiatric Interview-Plus. Participants were categorized into the MDD and non-MDD groups or depression group and non-depression group following the PHQ-9 score. Logistic regression analysis was performed to confirm the association between anger and suicidality in the non-MDD and non-MDD groups. Results: Anger suppression and higher PHQ-9 appeared as risk factors for suicidality in the non-MDD group. The depression level in the non-MDD group mediates the relationship between anger suppression and suicidality. Higher PHQ-9 was no longer a risk factor and anger suppression remains a risk factor in the non-depression group. Conclusion Not only depression evaluation, but also anger evaluation is important when assessing suicidality. Implementing anger management programs for people with high anger suppression can help lower suicidality in Korean society, where negative emotional expression is suppressed.

OBJECTIVE: The structural alteration of brain shown in patients with alcohol use disorder (AUD) can originate from both alcohol effects and genetic or developmental processes. We compared surface-based parameters of patients with AUD with healthy controls to prove the applicability of surface-based morphometry with head size correction and to determine the areas that were sensitive to brain alteration related to AUD. METHODS: Twenty-six abstinent male patients with AUD (alcohol group, mean abstinence=13.2 months) and twenty-eight age-matched healthy participants (control group) were recruited from an inpatient mental hospital and community. All participants underwent a 3T MRI scan. Surface-based parameters were determined by using FreeSurfer. RESULTS: Every surface-based parameter of the alcohol group was lower than the corresponding control group parameter. There were large group differences in the whole brain, grey and white matter volume, and the differences were more prominent after head size correction. Significant group differences were shown in cortical thicknesses in entire brain regions, especially in parietal, temporal and frontal areas. There were no significant group differences in surface areas, but group difference trends in surface areas of the frontal and parietal cortices were shown after head size correction. CONCLUSION: Most of the surface-based parameters in alcohol group were altered because of incomplete recovery from chronic alcohol exposure and possibly genetic or developmental factors underlying the risk of AUD. Surface-based morphometry with controlling for head size is useful in comparing the volumetric parameters and the surface area to a lesser extent in alcohol-related brain alteration.
