Purpose: The aim of this study was to evaluate the reliability of the Vectra M3 (3D Imaging System; Canfield Scientific, Parsippany, NJ, USA) in detecting chin asymmetry, and to assess whether the automatic markerless tracking function is reliable compared to manually plotting landmarks. Materials and Methods: Twenty subjects (18 females and 2 males) with a mean age of 42.5±10.5 years were included. Three-dimensional image acquisition was carried out on all subjects with simulated chin deviation in 4 stages (1-4 mm). The images were analyzed by 2 independent observers through manually plotting landmarks and by Vectra software auto-tracking mode. Repeated-measures analysis of variance and the Tukey post-hoc test were performed to evaluate the differences in mean measurements between the 2 operators and the software for measuring chin deviation in 4 stages. The intraclass correlation coefficient (ICC) was calculated to estimate the intra- and inter-examiner reliability. Results: No significant difference was found between the accuracy of manually plotting landmarks between observers 1 and 2 and the auto-tracking mode (P=0.783 and P=0.999, respectively). The mean difference in detecting the degree of deviation according to the stage was <0.5 mm for all landmarks. Conclusion: The auto-tracking mode could be considered as reliable as manually plotted landmarks in detecting small chin deviations with the Vectra<sup>®</sup> M3. The effect on the soft tissue when constructing a known dental movement yielded a small overestimation of the soft tissue movement compared to the dental movement (mean value<0.5 mm), which can be considered clinically non-significant.

The rapid global expansion of West Nile virus (WNV) has recently raised concerns regarding its possible spread into South Korea. To date, WNV infection in wild birds in South Korea has not been identified. Bird migration is thought to be involved in spreading WNV, and wild birds are the possible routes of introduction of WNV infection. To assess the risk of WNV infection in South Korea, we conducted a nationwide WNV surveillance of wild birds, with an emphasis on migratory ducks from WNV-affected areas. Our chief aim was to determine whether birds with the potential to introduce WNV are present in South Korea by testing migrating and resident wild birds for WNV antibodies. We collected blood samples from 1531 wild birds representing 57 bird species at several major inland resting sites for migratory waterfowl in South Korea. A seroepidemiological analysis of WNV and Japanese encephalitis virus (JEV) infections was conducted using plaque-reduction neutralization tests (PRNTs) for each virus. To search for recent WNV infections, sera were also evaluated by IgM antibody capture ELISA. Of the 1531 serum samples, 5 (0.3%) tested positive for WNV-specific antibodies, and 70 (4.6%) tested positive for JEV-specific antibodies. A total of 9 (0.6%) samples were positive for both WNV and JEV antibodies; these samples were interpreted as having a flavivirus exposure. All birds that had neutralizing antibodies specific to WNV were negative for IgM, which indicates the likelihood of a relatively old infection. Along with the recognized distribution of flaviviruses along several duck species' migratory routes, our findings strongly suggest that some of the birds captured in this study had been exposed to WNV or JEV.

Lived Experience of Thai Women with Alcohol Addiction

Purpose: This study explored the lived experiences of Thai women in relation to alcohol addiction in treatment. Methods: Twelve women aged 20 to 65 years, were participated. The participants were recruited from two special hospitals and one outpatient clinic in a general hospital. Descriptive phenomenology was applied to analyze the transcripts of the individual interviews. Result: The explored phenomenon of Thai women experiencing alcohol addiction included four essential aspects, (1) feeling inferior and worthless (2) feeling physically and emotionally hurt, (3) fearing physical deterioration and premature death, and (4) feeling superior and powerful. Through these different aspects of Thai women's lived experiences, the following essence was synthesized. The essence of the lived experience of alcohol addiction among the studied Thai women was ambivalence between feeling inferior and worthless and feeling superior and powerful when acting as a man. Drinking alcohol lessened life's difficulties and fears; for example, of violence, bodily demolition, premature death and marginalization from family and society. Conclusion: Thai women who experience alcohol addiction are treated with gender-related double standards when trying to undo gender traditional roles. Their marginalization from family and society deepens making them even more vulnerable to the positive side effects of alcohol drinking.
