PURPOSE: This study was conducted to investigate the influence of emotional labor, emotional dissonance, and burnout on nurse's turnover intention and examine the effect of job satisfaction on the relationships among emotional labor, emotional dissonance, burnout, and turnover intention. METHODS: The sample consisted of 350 nurses recruited from 6 general hospitals in 2 cities in Korea. A multiple-group analysis was utilized. Data were analyzed using SPSS statistics 23 and AMOS 20. RESULTS: In the path analysis, turnover intention was directly related to burnout in clinical nurses who had a high job satisfaction (β=.24, p=.003), while it was indirectly related to emotional dissonance (β=.13, p=.002). In the multiple-group path analysis, turnover intention was directly related to emotional dissonance (β=.18, p=.033) and burnout (β=.26, p=.002) for nurses with low job satisfaction. CONCLUSION: These results indicate that manuals and guidelines to alleviate the negative effects of emotional labor, emotional dissonance, and burnout, and to increase job satisfaction are strongly required to reduce turnover intention in nurses at the organizational level as well as at the individual level.

Background:
The current lack of the number of nurses and high nurse turnover rate leads to major problems for the health-care system in terms of cost, patient care ability, and quality of care. Theoretically, burnout may help link emotional labor with turnover intention. The purpose of this study was to investigate the mediating effect of burnout in the association between emotional labor and turnover intention in Korean clinical nurses.
Methods:
Using data collected from a sample of 606 nurses from six Korean hospitals, we conducted a multiple regression analysis to determine the relationships among clinical nurses' emotional labor, burnout, and turnover intention, looking at burnout as a mediator.
Results:
The results fully and partially support the mediating role of burnout in the relationship between the subfactors of emotional labor and turnover intention. In particular, burnout partially mediated the relationship between emotional disharmony and hurt, organizational surveillance and monitoring, and lack of a supportive and protective system in the organization. In addition, we found that burnout has a significant full mediation effect on the relationship between overload and conflicts in customer service and turnover intention. Although the mediating effect of burnout was significantly associated with the demands and regulation of emotions, no significant effects on turnover intention were found.
Conclusion
To reduce nurses' turnover, we recommend developing strategies that target both burnout and emotional labor, given that burnout fully and partially mediated the effects of emotional labor on turnover intention, and emotional labor was directly associated with turnover intention.

Background:
This study investigated the relationship between trauma exposure and suicidal ideation. Moreover, this study examines the moderating roles of organizational climate on the association between trauma exposure and suicidal ideation in Korean male firefighters.
Methods:
A total of 15,104 male firefighters who completed a questionnaire were analyzed. The data were obtained using an online self-administered questionnaire from the Firefighter Research on Enhancement of Safety and Health Study. Poisson regression analysis was performed to determine the effects of trauma exposure on suicidal ideation and the moderating effect of organizational climate.
Results:
The results showed that 389 firefighters (2.6%) responded that they had experienced suicidal ideation. In the final model, trauma exposure was positively related to suicidal ideation (adjusted risk ratio [aRR], 1.076; 95% confidence interval [CI]: 1.051–1.103), and organizational climate was negatively associated with suicidal ideation (aRR, 0.772; 95% CI: 0.739–0.806). Additionally, the interaction term (trauma exposure × organizational climate) was related to suicidal ideation (aRR, 1.016; 95% CI: 1.009–1.023).
Conclusions
This study suggests that trauma exposure might play a significant role in developing suicidal ideation and that positive organizational climate moderates the negative effects of trauma exposure on suicidal ideation among firefighters. It is necessary to perform a follow-up study of various intervention strategies to maintain a healthy organizational climate or work environment. Such interventions should promote lasting trust within teams, provide social support and belonging, and nurture job value.

Gastric cavernous hemangioma is a relatively rare benign gastric disease. Gastric hemangiomas are most commonly encountered in adulthood, although they can occur in any age group. While surgical resection is the curative treatment, endoscopic resection can be performed for treatment of selected cases. The patient was a 53-year-old male who was referred for evaluation of incidentally detected gastric subepithelial tumor with dense vascularity and oozing on the apex of the lesion. An EUS revealed a homogenously hypoechoic mass confined to the submucosal layer that showed no continuity with adjacent vessels, and there was no regional lymphadenopathy. Endoscopic submucosal dissection was successfully performed with en bloc resection. The final diagnosis was benign cavernous hemangioma of the stomach.

The purpose of this study was to examine the relationship between emotional labor and burnout, and whether the levels of self-efficacy and type A personality characteristics increase the risk of burnout in a sample of Korean female dental hygienists. Participants were 807 female dental hygienists with experience in performing customer service for one year or more in dental clinics, dental hospitals, or general hospitals in Korea. Data were collected using a structured self-administered questionnaire. A hierarchical multiple linear regression analysis was used to examine the effects of emotional labor on burnout, and to elucidate the additive effects of self-efficacy and type A personality on burnout. The results showed that “overload and conflict in customer service,”“emotional disharmony and hurt,” and “lack of a supportive and protective system in the organization” were positively associated with burnout. With reference to the relationship between personality traits and burnout, we found that personal traits such as self-efficacy and type A personality were significantly related to burnout, which confirmed the additive effects of self-efficacy and type A personality on burnout. These results indicate that engaging in excessive and prolonged emotional work in customer service roles is more likely to increase burnout. Additionally, an insufficient organizational supportive and protective system toward the negative consequences of emotional labor was found to accelerate burnout. The present findings also revealed that personality traits such as self-efficacy and type A personality are also important in understanding the relationship between emotional labor and burnout.

PURPOSE: It has been studied prognostic factors about secondary displacement after conservative treatment of the distal radius fracture, but each study showed different results. Authors retrospectively evaluated factors known to be involved secondary displacement of the distal radius fracture to determine its significance. METHODS: One hundred eighteen cases of the radiographically unstable distal radius fractures that closed reduction was adequately performed were retrospectively studied and the radiographic images were taken at 1, 2, 3, 4, 6 weeks after closed reduction. During follow-up, dorsal tilt more than 15°, volar tilt more than 20°, ulnar positive variance more than 4 mm, radial length less than 6 mm, radial inclination less than 10° were thought of the loss of reduction. RESULTS: In 41 cases (34.7%), the loss of reduction occurred. Sex, intra-articular fracture, dorsal and volar comminution, concomitant ulnar fracture and involvement of the distal radio-ulnar joint were statistically not significant. Analysis results of the binomial logistic regression model were as follows: age (p=0.003), radial shortening (p=0.010) and ulnar positive variance (p=0.010) were statistically significant as the predictive prognostic factors. Analysis results of the multinomial logistic regression model showed age (p=0.006) as an only statistically significant factor. CONCLUSION: As the predictive prognostic factors for development of secondary displacement after conservative treatment of the unstable distal radius fracture, age was determined as most significant factor. Also radial shortening and ulnar positive variance were thought of the predictive factors for secondary displacement.

PURPOSE: There are several kinds of classificatian dealing with the staging of the gastric adenocarcinoma. However, such different staging systems pose difficulty in the inter- institutional or intemational comparison of the disease status and the treatment results. The purpose of this study is to evaluate each staging system and to assess the usefulness of the new UICC-TNM staging system (1997) for gastric adenocarcinoma. MATERIAL AND METHODS: We retrospectively analysed 473 cases of gastric adenocarcinoma who were operated at the Department of General Surgery, Hanyang University Hospital during the period from 1992 to 1996. Using these cases, we analyzed their cumulative 5-year survival rate according to three kinds of staging systems; old UICC-TNM staging system (1987), new UICC-TNM staging system (1997), and the Japanese staging system for gastric carcinoma (1993). RESULTS: The follow up rate was 94.3% and the median follow up period was 30.3 months. All of these three systems showed a statistically significant survival difference according to their different classifications. When the distribution of stage between old and new UICC-TNM staging system was compared, 95 cases (20.1%) were subjected to stage shifting, which involves 12.1% of up-staging and 8.4% of down-staging. Stage shifting was most prominent in stage IIIb (68.8%). The cumulative 5-year survival rate according to the new UICC-TNM staging system was 99.1% in stage Ia, 81.4% in stage Ib, 75.2% in stage II, 45.9% in stage IIIa, 21.0% in stage IIIb, and 19.4% in stage IV. CONCLUSION: We conclude that the new UICC-TNM staging system is simple, practically convenient, and highly reproducible, and it showed a statistically significant survival difference according to their staging classification.

OBJECTIVE: To set up the methodology for PCR analysis of XbaI/intron 22 polymorphism of the factor VIII gene, and to identify the usefulness of XbaI/intron 22 polymorphism analysis for carrier detection and prenatal diagnosis of hemophilia A in the Korean population. DESIGN: A laboratory analysis. MATERIALS AND METHODS: A XbaI/intron 22 polymorphism of the factor VIII gene was analyzed in 56 unrelated Korean mothers of patients with severe hemophilia A, using polymerase chain reaction. RESULTS: Analysis of XbaI/intron 22 polymorphisms of the factor VIII gene were feasible by PCR method. The expected heterozygosity rates of XbaI/intron 22 polymorphism of the factor VIII gene were 44.8%. Analysis of XbaI/intron 22 polymorphism revealed heterozygous patterns in 22 (39.3%) of 56 mothers studied. Using linkage analysis with XbaI/intron 22 polymorphism, we have attempted one case of carrier detection and two cases of prenatal diagnosis in two families of patients with severe hemophilia A. CONCLUSION: These results suggest that PCR analysis of the XbaI/intron 22 polymorphism within the factor VIII gene is very useful in the carrier detection and prenatal diagnosis of hemophilia A in the Korean population.
