Development of the Battery Test for Screening of Depression and Mental Health: PROtective and Vulnerable factors battEry Test (PROVE) / 신경정신의학

Objectives@#This study developed a battery test that allows a comprehensive evaluation of depressive symptoms and related protective-vulnerable factors to screen for depression and mental health and examined the reliability and validity of the test. @*Methods@#PROtective and Vulnerable factors battEry test (PROVE) consisting of five sub-sections was developed: depressive symptomatology (PROVE-DS), suicide risk (PROVE-SR), and three protective-vulnerable factors, which were adult attachment type (PROVE-ATT), adverse childhood experience (PROVE-ACE), and mentalization capacity (PROVE-MC). Two hundred and thirteen subjects completed the PROVE test and other comparative scales, and the analysis was carried out based on the data. @*Results@#The PROVE test showed good convergent, discriminant, and concurrent validity as well as adequate internal consistency. In addition, five sub-sections of the PROVE test showed significant relevance to each other. @*Conclusion@#The results of this study indicate that the PROVE test is a reliable and valid test, which will be useful for the prevention, evaluation, and treatment of depression in various clinical settings.

Copycat Suicide Induced by Entertainment Celebrity Suicides in South Korea

OBJECTIVE: Throughout the past several years, there have been a number of entertainment celebrity suicides in South Korea. The aim of this study was to investigate the clustering of suicides following celebrities' suicides in South Korea from 2005 to 2008, particularly according to certain characteristics. METHODS: Seven celebrity suicides were examined and defined using the Korean Integrated Newspaper Database System (KINDS) and from these, we considered four affected periods occurring 28 days after each celebrity's suicide. A Poisson time-series autoregression model was used to estimate the relative risk of the total suicide number for each affected period from 2005 to 2008. Logistic regression analysis was performed to investigate whether there were specific increases in the numbers of suicides in subgroups matching each celebrity. RESULTS: There were significant increases in the risk of suicide during the affected periods. Remarkable increases were found in the subgroups matching each celebrity, especially in the group in which all factors (sex, age, and method) were similar. CONCLUSION: This study provides confirmation that a significant copycat effect was induced by these celebrities' suicides, especially among people who identified more with the celebrities. This implies that countermeasures for upright media coverage of celebrity suicides should be discussed and practiced properly in South Korea.

Comparative study of fracture strength depending on the occlusal thickness of full zirconia crown / 대한치과보철학회지

PURPOSE: The purpose of this study was to compare the fracture strength of traditional metal-ceramic crowns and full zirconia crowns according to the occlusal thickness. MATERIALS AND METHODS: A mandibular first molar resin tooth was prepared with 1.5 mm occlusal reduction, 1.0 mm rounded shoulder margin and 6degrees taperness in the axial wall. Duplicating the resin tooth, 64 metal dies were fabricated. 48 full zirconia crowns were fabricated using Prettau zirconia blanks by ZIRKONZAHN CAD/CAM and classified into six groups according to the occlusal thickness (0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm). 16 metal-ceramic crowns were fabricated and classified into two groups according to the occlusal porcelain thickness (1.0 mm, 1.5 mm). All crowns were cemented on each metal die and mounted in a universal testing machine. The load was directed at the functional cusp of each specimen until catastrophic failure occurred. One-way ANOVA, Tukey multiple comparison test (alpha=.05) and t-test (alpha=.05) were used. RESULTS: The results were as follows. 1. The test 1 group (646.48 N) showed the lowest fracture strength (P.05). The value of test 6 group (1781.24 N) was significantly higher than those of the other groups (P<.05). 2. There were no significant differences of the fracture strength of metal ceramic crowns according to occlusal porcelain thickness 1.0 mm (2515.71 N) and 1.5 mm (3473.31 N) (P<.05). CONCLUSION: Full zirconia crown needs to be 1.0 mm or over in occlusal thickness for the posterior area to have higher fracture strength than maximum bite force.
