PURPOSE: The purpose of this study was to identify the relationship of job stress, depression and to identify factors influencing suicide ideation of women-workers. METHODS: The research was a cross-sectional, descriptive study. Data collection was done using self-report questionnaires with 348 women-workers who agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, chi2-test, logistic regression analysis by using SPSS/WIN 18.0. RESULTS: The results showed, among the independent variables, drinking, job stress, depression are significant factors that influence women-workers' suicide ideation. Women-workers' depression is 3.05 times higher (p<.002), and job stress 1.03 times higher suicide ideation (p<.045), and drinking 2.15 times higher suicidal ideation (p<.006). CONCLUSION: The results indicate that suicide ideation is highly prevalent in women-workers, especially among people with depression and job stress. It is necessary to seek how to prevent and manage womenworkers' suicide ideation considering features.

PURPOSE: In adriamycin(ADR)-induced cardiomyopathy, several different mechanisms are suggested. However, little information is available regarding the role of apoptosis. In the present study, we examined the induction of apoptosis on ADR treatment and anti-apoptotic effects of probucol, a lipid-lowering drug, and we also studied the changes of bcl-2 expression in order to see the molecular mechanisms underlying the effect of probucol. METHODS: Cardiac myocytes were isolated from 3-day-old rats, and cultured in low(1 pM) or high doses(10pM) of ADR for 24 hours. Probucol(50 pM) was added 30 minutes before ADR administration. Apoptosis was determined by TUNEL staining, and bcl-2 expression was estimated by immunocytochemistry. RESULTS: The number of TUNEL-positive cells significantly increased in both groups treated with ADR. However, anti-apoptotic effect of probucol was evident only in low dose. In addition, the expression of bcl-2 was significantly increased only in the low-dose ADR treatment group and its expression was inhibited by pretreatment of probucol. CONCLUSION: These results suggest that apoptosis might play an important role in ADR-induced cardiotoxicity, and ADR-induced apoptosis was partially prevented by pretreatment of probucol. And ADR-induced apoptosis was not related with depression of bcl-2. Additionally, inhibition of bcl-2 gene expression of low-dose ADR treatment group by probucol suggests that another cell survival mechanism could be implicated in the action of probucol.

Primitive neuroectodermal tumors (PNET) of the ovary are rare tumors with an exclusive or almost exclusive malignant neuroectodermal composition, and are generally regarded as a monodermal expression of an ovarian teratoma. The tumors are basically identical with the lesions of the same name occuring typically in the central nervous system of children. These tumors consist chiefly of undifferentiated small cells resembling neuroblasts. There are also mature, well- differentiated neuroectodermal cells, such as astrocytes and ependymal cells. We report a case of ovarian PNET with glial and neuroblastic differentiation and focal teratomatous foci of non-neural tissue in a 17-year-old female.

PURPOSE: This study was conducted to compare the rates of industrial accidents in workplaces that adopted the 2011 Workplace Health Promotion Subsidy Scheme before and after the implementation. METHODS: The study analyzed the raw data of industrial accidents of 304 workplaces which received subsidies for health promotion activities in 2011. The raw data covered the period from February 2010 to July 2012, based on the dates of industrial accidents. RESULTS: Workplaces subsidized for health promotion activities reported fewer occurrences in staff injuries and illnesses than before the subsidization, as the total number of industrial accident victims dropped from 0.35 to 0.24. The rate of industrial accidents also dropped from 0.49 to 0.35, with the number of working days decreased from 35,433 to 23.867, about 33%. CONCLUSION: The study showed that financial support for health-promoting activities contributed to the decease in industrial accidents, which is an important indication advocating the need for corporate and government investment on workers health promotion programs. Furthermore, this study is also significant as it is the first research conducted in Korea to examine the impact of a workers health promotion project using a direct indicator, the rate of industrial accidents.

All ceramic restorations have had a more limited life expectancy than metal ceramic crowns because of their lower strength. The relatively lower strength has limited the use of all-ceramic crowns to the areas where occlusal loads are lower. Therefore many researches have been done to increase the strength of all-ceramic crowns. IPS Empress 2 is a new type of lithium disilicate glass-ceramic with enhanced physical characteristics which has been in use clinically since 1998. Previous researches reported that the flexural strength of all-ceramic material was greater than 300MPa, and all-ceramic crowns can be used in staining or layering technique. The objective of this study was to investigate the influence of the thickness of IPS Empress 2 ceramic on fracture strength. Both staining technique and layering technique was investigated. Vita VMK was used as control. For all three groups, five specimens each of 0.8mm, 1.0mm, 1.4mm, 1.8mm, and 2.2mm thickness (a total of 75 specimens) were prepared. Control group: Vita VMK Porcelain specimens were prepared with dentine ceramic and liquid glazing was done. Group I: IPS Empress 2 were prepared with staining technique and stained twice and glazed once. Group II : IPS Empress 2 were prepared with layering technique and glazed after wash firing. The thickness and diameter of the specimen were measured and controlled after specimen preparation. Biaxial Flexure Test (ASTM Standard F394-78) was adopted as this test method produces results least affected by the edge condition of the specimens. Fracture strength was measured with Instron Universal Testing Machine. Conclusions are as follow : 1. The fracture strength was increase in order of control group, test group I, test group II. 2. Fracture strength of the group I(Empress 2 Staining) was 65.54 N in 0.8mm, 155.2 N in 1.0mm, 233.5 N in 1.44mm, 434.5 N in 1.8mm, and 600.1 N in 2.2mm. 3. Fracture strength of the group II (Empress 2 Layering) was 190.0 N in 0.8mm, 283.5 N in 1.0mm, 437.2 N in 1.4mm, 732.0 N in 1.8mm, and 1115.0 N in 2.2mm. 4. No statistical difference was found in flexural strengths according to thickness in a specified group(p>0.05).
