Women doctors played an exceptional role during the period of modernization in Korea, making tremendous contributions toward the development of Korean society. The first woman doctor, Esther Park, started a community service program for women in adverse circumstances, but later, expanded it to serve both men and women equally. Esther Park's spirit of service earned her tremendous respect and inspired later generations of women doctors, whose contributions and competences have been acknowledged, and who made steps toward establishing and demanding sexual equality between men and women. In addition, women doctors have contributed to informing people on about important health issues, administering treatment, and preventing of disease. All these considerations demonstrate that during the modernization of Korea, women doctors played a crucial role in the national liberation movement. The most important aspect of this period was that women became role models in many parts of society and pioneered the path toward sexual equality. They became a symbol of responsibility and collective leadership for the following generations, and women doctors, in particular, were notable examples of the spirit of leadership.

Objectives: The aim of this study was to investigate dietary intakes and nutritional status among Uganda primary school children from two selected schools in urban and rural areas. Methods: Data were collected from 350 pupils (6-14 years) in Mpigi district, Uganda. All participants were offered a school lunch meal (usually maize porridge and boiled beans). Dietary survey was conducted in October 2016. Data for dietary intake levels were collected by the 24-hour recall method with trained school staffs. The data were converted into nutrient intakes using the CAN-Pro 5.0 Program and compared with KDRIs to evaluate the nutritional status of the subjects. Diet quality indexes such as nutrient density, nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) and a diet diversity index such as diet diversity score (DDS) were calculated to evaluate nutritional status among subjects. Data were analyzed using SPSS statistical programs. Results: Results show that the intakes of most nutrients were significantly different by schools. The nutritional status of micro-nutrients was very low in both schools according to analysis of nutritional indexes such as NARs and INQs. Students from both schools should improve intakes of micro-nutrients related to child growth such as calcium, Vitamin B6, zinc and folate. According to the analysis of dietary diversity, there was difference in dietary patterns by schools presumably due to their locations. Conclusions This suggests that current meals could not provide adequate nutrients for the subjects and urgent nutrition interventions for school food services are needed to improve their nutritional well-being. New foods supplements based on local cuisine are also needed to ensure dietary diversity and sustainable development plans.

BACKGROUND: Avoparcin, cross-resistance with vancomycin, was added as feed-additive since 1970s and was prohibited in 1997 in Korea. After avoparcin was banned we examined prevalence and genetic relatedness of VRE in enterococci isolated from livestock and humans. MATERIALS AND METHODS: Using enrichment broth and 6 microgram/mL vancomycin-containing enterococcosel selective agar, vancomycin-resistant enterococci (VRE) were isolated from fecal sample of 255 pigs of 8 farms, 431 chickens of 9 farms, and 328 humans (Food industry employee and Institution cafeteria employee) of 5 public health centers, and 100 raw chicken meats from April to June 2003. Antimicrobial susceptibility was examined by disk diffusion and minimum inhibitory concentrations (MICs), and E-test. Species identification and genotyping were done by multiplex PCR method. Pulsed-field gel electrophoresis (PFGE) of vanA-type VRE isolates was performed by CHEF-Mapper system. RESULTS: 19 isolates from 255 pigs, 122 isolates from 431 chickens, 19 isolates from 100 raw chicken meat, and 7 isolates from 328 humans were resistant to vancomycin. Of the 167 VRE isolates, vanA gene was detected in 141 isolates; 1 isolate (0.4%) in pigs, 121 isolates (28.1%) in chickens, 18 isolates (18.0%) in raw chicken meat, and 1 isolate (0.3%) in humans. Resistant rates of streptomycin, tetracycline, and erythromycin were over 60% in vanA-type E. faecium isolated from poultry. PFGE analysis resulted in two major patterns, F and P types. Also PFGE pattern of 1 VRE from human was identical to that of 1 VRE from poultry. CONCLUSION: Despite the high prevalence of vanA-type VRE in poultry farms, VRE isolation rate in human was relatively low. This result suggests that the possibility of VRE transmission from poultry to human is low but that possibility may be not ruled out. In PFGE analysis showing 51.5% identical in 2 PFGE patterns, the dissemination of VRE isolates in poultry may be transmitted vertically and horizontally.

Group 3 innate lymphoid cells (ILC3), which express IL-22 and IL-17A, has been introduced as one of pathologic cells in axial spondyloarthritis (axSpA). Dyslipidaemia should be managed in axSpA patients to reduce cardiovascular disease, and dyslipidaemia promotes inflammation. This study aimed to reveal the role of circulating ILC3 in axSpA and the impact of dyslipidaemia on axSpA pathogenesis. AxSpA patients with or without dyslipidaemia and healthy control were recruited. Peripheral blood samples were collected, and flow cytometry analysis of circulating ILC3 and CD4+ T cells was performed. The correlation between Ankylosing Spondylitis Disease Activity Score (ASDAS)-C-reactive protein (CRP) and circulating immune cells was evaluated. The effect of oxidized low-density lipoprotein cholesterol (oxLDL-C) on immune cell differentiation was confirmed. AxSpA human monocytes were cultured with with oxLDL-C, IL-22, or oxLDL-C plus IL-22 to evaluate osteoclastogenesis using tartrate-resistant acid phosphatase (TRAP) staining and realtime quantitative PCR of osteoclast-related gene expression. Total of 34 axSpA patients (13 with dyslipidaemia and 21 without) were included in the analysis. Circulating IL-22+ ILC3 and Th17 were significantly elevated in axSpA patients with dyslipidaemia (p=0.001 and p=0.034, respectively), and circulating IL-22+ ILC3 significantly correlated with ASDAS-CRP (Rho=0.4198 and p=0.0367). Stimulation with oxLDL-C significantly increased IL-22+ ILC3, NKp44 − ILC3, and Th17 cells, and these were reversed by CD36 blocking agent. IL-22 and oxLDL-C increased TRAP + cells and osteoclast-related gene expression. This study suggested potential role of circulating IL-22+ ILC3 as biomarker in axSpA. Furthermore, dyslipidaemia augmented IL-22+ ILC3 differentiation, and oxLDL-C and IL-22 markedly increased osteoclastogenesis of axSpA.

In this study, the Ti6Al4V specimens were fabricated using selective laser melting (SLM) method (Ti6Al4V-AS group). These specimens were performed to heat treatment at 950℃ and 550℃ using vacuum electric furnace (Ti6Al4V-HT group). The mechanical properties, metallographic shape, crystalline structure, and chemical compositions of the alloy specimens before and after heat treatment were analyzed. The Ti6Al4V-AS group showed ultimate tensile strength (UTS) and low elongation values. Acicular crystal grains were observed in metallographic image and the α'-Ti phase was dominant. After heat treatment (Ti6Al4V-HT group), the UTS was lowered and the elongation was increased. In addition, a lamellar structure in which columnar crystal grains are arranged was observed, α+β-Ti phase was formed, and crystallinity increased. As a result of analyzing the chemical composition, the Ti6Al4V-AS specimen contained a higher carbon content than the Ti6Al4V-HT specimen. This high carbon content could be related to the formation of α'-phase, high strength and low elongation of the Ti6Al4V-AS specimen. Ti6Al4V-HT specimen showed that the overall carbon content was low, but the carbon content was locally high in the α-Ti phase region. Therefore, it is necessary to control effectively the incorporation of carbon gas in the production of Ti6Al4V specimens using SLM.
