The purpose of this study was to examine the mediating effect of career resilience and its sub-variables in the relationship between career barriers and career preparation behavior. Toward this end, 338 college students were selected as subjects of the study. Data analysis was performed using SPSS 25.0 and the process macro of Hayes. The main research results are as follows. First, the career barrier showed significant negative correlations with career preparation behavior, career resilience, and the sub-variables of career resilience. The career preparation behavior showed significant positive correlations with career resilience and the sub-variables of career resilience. Second, the career resilience showed a significant complete mediating effect in the relationship between career barrier and career preparation behavior. This means that when career resilience was mediated, career barriers affected career preparation behavior through career resilience; however, career barrier did not directly affect career preparation behavior. Third, the achievement aspiration and career self-reliance showed a significant mediating effect in the relationship between career barrier and career preparation behavior. However, self-confidence, coping with change, and relationship utilization did not show significant mediating effects. Based on these findings, the implications of career education and suggestions for subsequent research were discussed.

BACKGROUND: Antibiotics used in animal husbandry for disease prevention and treatment have resulted in the rapid progression of antibiotic resistant bacteria which can be introduced into the environment through livestock feces/manure, disseminating antibiotic resistant genes (ARGs). In this study, fecal samples were collected from the livestock farms located in Jeju Island to investigate the relationship between microbial communities and ARGs. METHODS AND RESULTS: Illumina MiSeq sequencing was applied to characterize microbial communities within each fecal sample. Using quantitative PCR (qPCR), ten ARGs encoding tetracycline resistance (tetB, tetM), sulfonamide resistance (sul1, sul2), fluoroquinolone resistance (qnrD, qnrS), fluoroquinolone and aminoglycoside resistance (aac(6')-Ib), beta-lactam resistance (bla_TEM, bla_CTX-M), macrolide resistance (ermC), a class 1 integronsintegrase gene (intI1), and a class 2 integrons-integrase gene (intI2) were quantified. The results showed that Firmicutes and Bacteroidetes were dominant in human, cow, horse, and pig groups, while Firmicutes and Actinobacteria were dominant in chicken group. Among ARGs, tetM was detected with the highest number of copies, followed by sul1 and sul2. Most of the genera belonging to Firmicutes showed positive correlations with ARGs and integron genes. There were 97, 34, 31, 25, and 22 genera in chicken, cow, pig, human, and horse respectively which showed positive correlations with ARGs and integron genes. In network analysis, we identified diversity of microbial communities which correlated with ARGs and integron genes. CONCLUSION(S): In this study, antibiotic resistance patterns in human and livestock fecal samples were identified. The abundance of ARGs and integron genes detected in the samples were associated with the amount of antibiotics commonly used for human and livestocks. We found diverse microbial communities associated with antibiotics resistance genes in different hosts, suggesting that antibiotics resistance can disseminate across environments through various routes. Identifying the routes of ARG dissemination in the environment would be the first step to overcome the challenge of antibiotic resistance in the future.

Objectives: This study aimed to assess the exposure levels of tollbooth workers to diesel particulate matter using black carbon (BC) and to find the correlations among variables associated with BC using the motor vehicle management act regulated by the Ministry of Land, Infrastructure and Transport. Methods: This study was performed over 14 days at a university in Seoul. BC levels were monitored using an aethalometer and were conducted around the breathing zones of the workers. There were three sampling locations: inside the tollbooth (front gate and rear gate) and an office as a control group. T-test, correlation, and multiple linear regression analysis were performed using SPSS. Results: The geometric mean (GM) of BC_30min concentrations in the exposure group was 2.44 ㎍/㎥, approximately 1.4 times higher than the control group (1.75 ㎍/㎥). The GM of BC_30min concentrations was 2.75 ㎍/㎥ during the heavy traffic time (9-10 am) and 2.30 ㎍/㎥ during non-heavy traffic times (p<0.001). The multiple linear regression analysis shows that the number of all types of vehicles and PM_2.5 concentrations in the atmosphere were factors increasing the GM of BC(ln(BC_30min)) concentrations (adjusted R²=0.42, p<0.001). The workers were constantly exposed to low concentrations (GM of BC_30min=2.44 ㎍/㎥), but they were exposed to peak concentrations instantly (BC_10sec=3545.04 ㎍/㎥). When the GM of BC_30min concentrations was momentarily represented as high, it was identified that a vehicle mainly using diesel fuel or an aging vehicle had passed. Conclusions: A ventilation system should be installed in the closed tollbooth or aging vehicles should be controlled so as not to pass tollbooths.

Objective: A developmental venous anomaly (DVA) is a vascular malformation of ambiguous clinical significance. We aimed to quantify the susceptibility of draining veins (χ_vein) in DVA and determine its significance with respect to oxygen metabolism using quantitative susceptibility mapping (QSM). Materials and Methods: Brain magnetic resonance imaging of 27 consecutive patients with incidentally detected DVAs were retrospectively reviewed. Based on the presence of abnormal hyperintensity on T2-weighted images (T2WI) in the brain parenchyma adjacent to DVA, the patients were grouped into edema (E+, n = 9) and non-edema (E-, n = 18) groups. A 3T MR scanner was used to obtain fully flow-compensated gradient echo images for susceptibility-weighted imaging with source images used for QSM processing. The χ_vein was measured semi-automatically using QSM. The normalized χ_vein was also estimated. Clinical and MR measurements were compared between the E+ and E- groups using Student's t-test or Mann-Whitney U test. Correlations between the χ_vein and area of hyperintensity on T2WI and between χ_vein and diameter of the collecting veins were assessed. The correlation coefficient was also calculated using normalized veins. Results: The DVAs of the E+ group had significantly higher χ_vein (196.5 ± 27.9 vs. 167.7 ± 33.6, p = 0.036) and larger diameter of the draining veins (p = 0.006), and patients were older (p = 0.006) than those in the E- group. The χ_vein was also linearly correlated with the hyperintense area on T2WI (r = 0.633, 95% confidence interval 0.333-0.817, p < 0.001). Conclusion: DVAs with abnormal hyperintensity on T2WI have higher susceptibility values for draining veins, indicating an increased oxygen extraction fraction that might be associated with venous congestion.

Purpose: The purpose of this study was to compare the quality of sleep with the serum lipid profile in patients who have restless legs syndrome (RLS). Methods: The data were obtained from 116 patients with RLS through questionnaires and blood sampling. Results: The results of this study showed correlations between lower quality of sleep and serum lipid profile (LDL Cholesterol) in patients with RLS (r=.19, p=.040). There were correlations for scores of quality of sleep from the, Pittsburgh Sleep Quality Index (PSQI) sub-region between lower subjective sleep quality and serum lipid profile (LDL Cholesterol) (r=.20, p=.026), between fewer hours of sleep duration and serum lipid profile (Total Cholesterol) (r=-.21, p=.024), and, between higher daytime dysfunction and serum lipid profile (LDL Cholesterol) (r=.42, p<.001) of patients with RLS. Conclusion: Pati-ents with RLS have sleep disorders with lower quality of sleep and changes in the serum lipid profile for total cholesterol and LDL cholesterol. That is, patients with RLS have lower quality of sleep and dyslipidemia compared to persons without RLS. Further research is needed to monitor serum the lipid profile in early stage symptoms of midlife adult patients with RLS and especially older women.

This study investigated consumers' clothing expense, consumer innovativeness and perceived risk to the channel type they frequently purchase fashion products and compared the relationship between the variables. A survey of male and female college students was conducted and 367 responses were analyzed using descriptive statistics, chi-square analysis, two-way ANOVA, factor analysis, reliability analysis, and correlations. Female consumer clothing expenses were high compared to male consumers, and clothing expenses of consumers using department stores and independent banded stores were high compared to those using internet shopping malls. The sub-dimensions of consumer innovativeness were determined as adventure-oriented, unique-oriented, and change-oriented, and female consumers have characteristics more unique-oriented and change-oriented. In the case of female respondents, unique-oriented innovativeness was highest for department store customers, while the male customer of non-branded stores showed the highest unique-oriented innovativeness. Perceived risk indicated the highest score from the customers of internet shopping mall. Department stores were recognized as reliable by female department store customers. Clothing expenses and consumer innovativeness dimensions showed significantly positive correlations; in addition, the relation between clothing expense and perceived risks were significantly negative. Consumer innovativeness and perceived risks have positive relations.

Purpose: The purpose of this study was to investigate emergency nurses' reported traumatic events, professional quality of life and physical symptoms. Methods: The design of the study was descriptive. The respondents were 157 Emergency nurses with the majority were women (94.3% female and 5.7% were men). Data were collected from September 28 to December 1, 2011. The professional quality of life (ProQOL) instrument is conceptualized with three sub-dimensions (compassion satisfaction, burnout, and secondary traumatic stress), in addition information about traumatic events, physical symptoms and demographic variables were collected. Burnout and secondary traumatic stress (STS) are two parts of compassion fatigue. Data were analyzed using the SPSS/WIN 18.0 program and included descriptive statistics, t-test, ANOVA, Pearson's correlations. Results: Thirteen percent of the participants reported a high ProQOL. Compassion satisfaction was negatively correlated with burnout and physical symptoms, whereas, traumatic events had positive correlations with STS. Also, burnout and STS were positively correlated with physical symptoms respectively. Conclusion: Since the level of professional quality of life among emergency nurses was relatively low it is recommended that an intervention program for emergency nurses be instituted to improve compassion satisfaction and to decrease compassion fatigue and physical symptoms.
