Purpose: The aim of this study was to identify factors related to the vaccination intentions of nursing students before clinical practice. Methods: A descriptive correlational study design was used. The participants were 129 nursing students who were enrolled in one college of nursing in Seoul and were scheduled for clinical training. Data collection was conducted from February 28 to March 7, 2022. The data were analyzed using descriptive statistics, a t-test, ANOVA, Pearson's correlation coefficient, and a latitudinal regression analysis using the IBM SPSS statistics version 26.0 program. Results: The intention to vaccinate showed a significant correlation with vaccination attitude (r=.72, p<.001), subjective norms (r=.68, p<.001), and perceived behavioral control (r=.63, p<.001). The influencing factors on three intent to vaccinate were vaccination attitude (β=.36 p<.001), subjective norms (β=.31, p<.001), and perceived behavioral control (β=.36, p<.001). The explanatory power of these variables was 69.6%. Conclusion: The vaccination rate before the clinical training of nursing students was related to economic burden, a lack of time, and transportation problems that nursing college students experienced during the vaccination process. Therefore, administrative and financial support is needed for improving the vaccination rates of nursing students.

Background: This study aimed to determine the utility and a cut-off level of serum squamous cell carcinoma antigen (SCC-Ag) to predict lymph node metastasis in locally advanced cervical cancer cases. We also investigated the correlation between SCC-Ag level and lymph node status. Materials and Methods: From June 2009 to June 2014, 232 patients with cervical cancer stage IB2-IVA, who were treated at Ramathibodi Hospital, were recruited. Receiver operating characteristic (ROC) curves were used to identify the best cut-off point of SCC-Ag level to predict lymph node metastasis. Quantile regression was performed to evaluate the correlation between SCC-Ag levels and pelvic lymph node metastasis, paraaortic lymph node metastasis, and parametrial involvement as well as tumor size. Results: Pelvic lymph node metastasis and paraaortic lymph node metastasis were diagnosed in 46.6% and 20.1% of the patients, respectively. The median SCC-Ag level was 6 ng/mL (range, 0.5 to 464.6 ng/mL). The areas under ROC curves between SCC-Ag level and pelvic lymph node metastasis, paraaotic lymph node metastasis, parametrial involvements were low. SCC-Ag level was significantly correlated with paraaortic lymph node status (p=0.045) but not with pelvic lymph node status and parametrial involvement. SCC-Ag level was also related to the tumor diameter (p<0.05). Conclusions: SCC-Ag level is not a good predictor for pelvic and paraaortic lymph node metastasis. However, it is still beneficial to assess the tumor burden of squamous cell carcinoma of the cervix.

Objective: The purpose of this research is to examine the effects of three types of different running shoes with different properties on impact variables (PVRGF and VLR) and the lower extremity joint's dynamic stability variables (LyEs of DPA, IEA, FEA, DPAV, IEAV, and FEAV) during running. Method: The participants in this research were 12 males (Age: 22.0 ± 3.3 years, Height: 177.2 ± 4.1 cm, Weight: 74.3 ± 9.6 kg). One type of N company's running shoes and two types (FA, FB) of F company's running shoes were used. As for the properties of the running shoes, thickness (mm), dwell time (ms), peak acceleration (m/s2), and energy return (%) were measured. The motions running at 3.5 m/s on a treadmill (Instrumented treadmill, Bertec, USA) wearing each type of running shoes were analyzed. Results: Although the VLR of the thick running shoes (FB) was smaller than that of the other running shoes (N, FA), the LyEs of PVGRF and DPA were larger (p<.05). Even though the running shoes' dwell time (i.e., impact absorption time) and peak acceleration showed a positive correlation with the LyEs of DPAV, IEAV, and FEAV, the energy return showed a negative correlation (p<.05). Conclusion: Our results indicated that the running shoes with excellent impact absorption function are predicted to be suitable for running beginners who need to reduce the burden of the lower extremity joint during running. The running shoes with excellent energy return are expected to be suitable for mid-and long-distance running elite athletes or marathoners to whom stability and consistency are essential during running.

This study was performed to evaluate chromium in air and chromium concentrations in whole blood and urine of workers at chrome plating factories, and to determine the correlation between environmental and biological chromium levels. This study involved 29 workers as study group and 24 undergraduate students as control group. The geometric means(GM) of airborne hexavalent chromium and total chromium concentrations in the plating factories were 3.4 $\mu\textrm{g}$/㎥ and 10.8 $\mu\textrm{g}$/㎥, respectively. Hexavalent chromium levels in two of total 29 measurements exceeded the korean occupational exposure limit and the American Conference of Governmental Industrial Hygienists Threshold Limit Value(ACGIH-TLV) of 50$\mu\textrm{g}$/㎥. Only one sample for total chromium exceeded the Korea occupational exposure limits, the ACGIH-TLV, and the National Institute for Occupational Safety and Health Recommended Exposure Limits(NIOSH-REL) of 500 $\mu\textrm{g}$/㎥. The GM of chromium concentrations in blood and urine of workers exposed to chromium were 8.4 $\mu\textrm{g}$/L and 11.9 $\mu\textrm{g}$/L. The GM of chromium concentrations in blood and urine of workers exposed to chromium were 8.4 $\mu\textrm{g}$/L and 11.9 $\mu\textrm{g}$/L, respectively, whereas the chromium concentrations in blood and urine of the controls were 1.6 $\mu\textrm{g}$/L and 3.8 $\mu\textrm{g}$/L, respectively. There were statistically significant differences of blood and urine concentrations between study group and control group (p<0.01). The chromium concentrations in urine were most highly related to hexavalent chromium, concentration in air(r=0.642, p<0.01). Also, there was a relatively high correlation between the hexavalent chromium concentrations in air and chromium concentrations in whole blood(r=0.557, p<0.05). These results indicate that whole-blood chromium with urinary chromium could be an indicator of chromium body burden caused by exposure to chromic acid mist in plating operation.

Objectives: This study aims to understand the stress patterns and coping behaviors of women with infertility and to improve existing infertility stress assessment tools to develop a tool suited for Korean society. Methods: The study involved 10 women diagnosed with primary or secondary infertility. Data were collected through surveys and in-depth interviews. Participants were recruited voluntarily, and snowball sampling was used for additional recruitment. Data collection occurred from September 2023 to April 2024. Data analysis included Spearman's rank correlation, Mann-Whitney U test, and Kruskal-Wallis test. Interview results were analyzed using text mining and network analysis with Python 3.12. Results: There was a significant correlation between IVF/ICSI treatment and resilience scores, with non-IVF/ICSI groups showing higher resilience scores. Existing infertility stress assessment tools were generally useful but had limitations, such as discomfort with religious expressions and fixed gender roles, as well as issues with the number of items and response scales. Text mining of interview responses revealed key stress-related keywords including worry, depression, burden, pregnancy outcome, and health. Main stressors included uncertainty about pregnancy outcomes, physical discomfort during treatments, economic burdens, and emotional reactions from family and social relationships. Conclusions: This study identified the stress patterns of women with infertility through interviews. It showed the need for a new assessment tool to evaluate and support the complex stressors experienced by these women. Developing a comprehensive tool is essential for better understanding and managing the various stress factors faced by infertile women.

Recently, interest in BIM technology has been growing in the domestic construction market as the number of construction projects requiring the application of BIM technology has increased. The use of BIM allows the use of various visualization functions through 3D models as well as drawing interference review, quantity calculation and integrated management of information. In particular, estimates of construction costs based on BIM can increase work efficiency by reducing the burden of calculating construction costs and managing them. In order to increase the efficiency of BIM-based cost estimates, it is necessary to improve the correlation between the BoQ(Bill of Quantity) information and the BIM model. For this purpose, the ratio of the amount and item to the detailed construction of the current BoQ was analyzed, especially the problem of the calculation of construction cost in the window work in this study. In addition, we would like to suggest a method for systematically linking the BoQ information with the BIM model by improving the BoQ information structure of the window work. It is expected that this will increase the efficiency of the quantity calculation and analysis work of construction cost of window work. In addition, it is expected that this method will help to analyze and predict changes in construction cost of windows and doors by facility characteristics and type.
