OBJECTIVES: This research was conducted to identify the consumers' food choice factors that affect the consumers' replacement of soft drinks with carbonated water. METHODS: The present study used secondary data from a consumer panel survey conducted by the Rural Development Administration of Korea, and the data included the panel members' purchase records based on their monthly spending receipts. The survey asked the participants about their food choice factors and their personal responsibility for their health. This survey included independent variables for the consumers' food purchase factors. As a dependent variable, two types of groups were defined. The replacement group included those people who increased their purchase of carbonated water and decreased their purchase of soft drinks. The non-replacement group included those people who did not change their purchase patterns or they increased their purchase of soft drinks and they decreased their purchase of carbonated water. Logistic regression analysis was conducted to determine the consumers' food choice factors that were associated with replacing soft drinks with carbonated water. RESULTS: The replacement group was significantly associated with (1) a younger age (OR=0.953), (2) being a housewife (OR=2.03), (3) higher income (OR=1.001) and (4) less concern about price (OR=0.819) when purchasing food. This group also showed (5) higher enjoyment (OR=1.328) when choosing food and (6) they took greater responsibly for their personal health (OR=1.233). CONCLUSIONS: This research is the first study to mainly focus on soft drinks and carbonated water. The result of this research showed that young, health-conscious consumers with a higher income and who are more interested in food have more possibilities to replace soft drinks with carbonated water. These research findings may be applied to consumers who have characteristics that are similar to the young health-conscious consumers and the results can help to suggest ways to reduce sugar intake and improve public health. However, this research has a limitation due to the application of secondary data. Therefore, a future study is needed to develop detailed survey questions about food choice factors and to extend these factors to all beverages, including soft drinks made with sugar substitutes, so as to reflect the growth of alternative industries that use artificial sweeteners or different types of sugar to make commercially available drinks.

Objectives: ：Screening of male depression is important since their symptoms differ from females, such as more common suicide attempts and aggression. Rutz et al. designed the Gotland Male Depression Scale (GMDS) to understand male depression and prevent suicide. The aim of this study is to translate the GMDS into Korean and assess the factor structure of K-GMDS. Methods: ：The K-GMDS was administered to 213 male office workers in one public institution. The current study used exploratory factor analysis to validate the factor structure and used confirmatory factor analysis to test the construct validity of five factor models from prior research. Results: ：The result indicated that the K-GMDS is characterized by a two-factor structure, different from originally proposed GMDS factor structure and other prior models. Fit indices demonstrated the prior five models to be a poor fit to the data. The internal consistency was demonstrated by a Cronbach’s α of 0.921. Conclusions ：This study can be used as a basis study of male depression, which has not been studied much in Korea. Though factor structure of GMDS reported discrepant findings with prior studies, it would help further development of the scale.

Objective: Despite lower depression rates in men than in women, men’s suicide rates are significantly higher, suggesting potential gaps in depression screening. Rutz et al. developed the Gotland Male Depression Scale (GMDS), which includes symptoms commonly associated with male depression. This study was conducted to validate the Korean version of the GMDS (K-GMDS). Methods: The K-GMDS, Patient Health Questionnaire-9 (PHQ-9), and outpatient records of 233 new patients at the outpatient psychiatry department of Catholic University Hospital in Daegu from February and May 2022 were retrospectively reviewed. Internal consistency was measured using Cronbach’s α, and external validity was tested by analyzing the scale’s correlation with the PHQ-9. The screening capacity of the K-GMDS was tested based on the receiver operating characteristic (ROC) curve, sensitivity, specificity, and overall accuracy. Results: Of 233 patients, 42.6% (n=98) were classified to the depression group. Cronbach’s α was 0.92, and external validity was established with a Pearson’s correlation coefficient of 0.83 between the total score of the K-GMDS and the PHQ-9. While there were no significant differences in the area under the ROC curve between the K-GMDS and the PHQ-9, the K-GMDS had better sensitivity, specificity, and overall accuracy in screening depressive symptoms among men compared to the PHQ-9. Conclusion The K-GMDS exhibits satisfactory reliability and validity in psychiatric outpatient settings and outperforms the PHQ-9 in screening for depression among men. This study will be useful in developing male depression scales that are currently unavailable in South Korea.

BACKGROUND: Any data on the prevalence of the infectious diseases of blood donors at a university hospital-based blood bank is not available. We aimed to analyze the seroincidence of screening tests from blood donors at a university hospital-based blood bank in Korea. METHODS: We retrospectively analyzed all the samples of blood donors during the previous three years from January 2006 to December 2008. HBsAg and HIV Ab/Ag Combo test were performed by chemiluminescent immunoassays, and anti-HCV was performed by enzyme-linked immunosorbent assay and electrochemiluminescent immunoassay. Serologic testing for syphilis was done by VDRL (venereal disease research laboratory test) and RPR (rapid plasma regain test). RESULTS: The number of total blood donors that underwent screening tests were 1,279 in 2006, 1,355 in 2007 and 941 in 2008, respectively. HBsAg was positive in 8 cases among the 1,279 donors (0.63%) in 2006, in 10 cases of the 1,355 donors (0.74%) in 2007 and in 5 cases of the 941 donors (0.53%) in 2008. Anti-HCV was positive in 3 cases (0.24%) in 2006, 2 cases (0.15%) in 2007 and 2 cases (0.21%) in 2008. One of them was dual positive for HBsAg and anti-HCV. There's no positive case of anti-HIV (0%) during the 3 years. Serologic testing for syphilis (VDRL) was positive in 7 cases (0.55%) in 2006, in 5 cases (0.37%) in 2007 and in 5 cases (0.53%) in 2008. CONCLUSION: The seroincidence was different between a university hospital-based blood bank and the Korean Red Cross Blood Service center. This difference might be due to the composition of donors, i.e., autologous blood donors and directed donors in the university-based blood bank.

Background: This study examined the impact of the performance improvement and patient safety (PIPS) program implemented in 2015 on outcomes for trauma patients in a regional trauma center established by a government-led project for a national trauma system in Korea. Methods: The PIPS program was based on guidelines by the World Health Organization and American College of Surgeons. The corrective strategies were proceeded according to the loop closure principle: data-gathering and monitoring, identification of preventable trauma deaths (PTDs), evaluation of preventable factors, analysis of findings, and corrective action plans. We established guidelines and protocols for trauma care, conducted targeted education and peer review presentations for problematic cases, and enhanced resources for improvement accordingly. A comparative analysis was performed on trauma outcomes over a four-year period (2015–2018) since implementing the PIPS program, including the number of trauma team activation and admissions, time factors related to resuscitation, ventilator duration, and the rate of PTDs. Results: Human resources in the center significantly increased during the period; attending surgeons responsible for trauma resuscitation from 6 to 11 and trauma nurses from 85 to 218. Trauma admissions (from 2,166 to 2,786), trauma team activations (from 373 to 1,688), and severe cases (from 22.6 to 33.8%) significantly increased (all P < 0.001). Time to initial resuscitation and transfusion significantly decreased from 120 to 36 minutes (P < 0.001) and from 39 to 16 minutes (P < 0.001). Time to surgery for hemorrhage control and decompressive craniotomy improved from 99 to 54 minutes (P < 0.001) and 181 to 135 minutes (P = 0.042). Ventilator duration and rate of PTDs significantly decreased from 6 to 4 days (P = 0.001) and 22.2% to 8.4% (P = 0.008). Conclusion Implementation of the PIPS program resulted in improvements in outcomes at a regional trauma center that has just been opened in Korea. Further establishment of the PIPS program is required for optimal care of trauma patients.
