  • Purpose: This study was done to examine sexual autonomy of college students. Method: Between October 2012 and November 2012, data related to self-efficacy, health knowledge, attitude to sex, and sexual autonomy orientation, were collected by questionnaire from 232 students. The data analysis was performed using PASW (SPSS) 18.0 program, and included t-test, one-way ANOVA, Pearson correlation coefficients, and multiple stepwise liner regression analysis. Results: The results showed a positive correlation between self-efficacy and sexual autonomy (r=.56, p<.001), sexual health knowledge (r=.50, p<.001), and attitude to sex (r=.29, p=.001). These 4 variables accounted for 48.7% of the variance in sexual autonomy among college students. Conclusion: The results of this study indicate that there is a need to develop mental health nursing strategies for college students in order to provide effective counseling on sexuality and sexual health matters.

  • The swivel joint is an important part in hydraulic machine. The analysis on the material was made using the EDAX method to localize the swivel joint. Also, the modeling and design drawing were finalized with application of 3 dimensional measurement and structure analysis. The prototype product based on design drawing was made with cutting and grinding process. No abnormalities were found in the prototype product through the durability test and measurement. The localized swivel joint with light weight, price reduction and diversification was developed in this study.

  • Soft storey failure mechanism is a common collapse mode for masonry-infilled (MI) reinforced concrete (RC) buildings subjected to severe earthquakes. Simple analytical equations correlating global with local ductility demands are derived from pushover (PO) analyses for seismic assessments of regular MI RC frames, considering the critical interstorey drift ratio, number of storeys and lateral loading configurations. The reliability of the equations is investigated using incremental dynamic analyses for MI RC frames of up to 7 storeys. Using the analytical ductility relationship and a coefficient-based method (CBM), the response spectral accelerations and period shift factors of low-rise MI RC frames are computed. The results are verified through published shake table test results. In general applications, the analytical ductility relationships thus derived can be used to bypass the onerous PO analysis while accurately predicting the local ductility demands for seismic assessment of regular MI RC frames.

  • Purpose: To study the perception and satisfaction of in-person and online classes for dental technology students. Methods: A total of 420 questionnaires were distributed to dental technology students between June 1 and June 30, 2021. Of these, 225 questionnaires were assessed using frequency analysis, one-way analysis of variance, Pearson's Chi-squared test, and independent t-tests via IBM SPSS Statistics ver. 22.0 (IBM). Results: For theory subjects, satisfaction was higher for online classes than in-person classes (p=0.001). For practical subjects, satisfaction was higher for in-person classes than online classes (p=0.002). Both the learning effect and motivation for learning were higher for in-person classes than online classes (p=0.001). Conclusion: When in-person and online classes become coexistent, there should be educational guidelines for improving the quality and effectiveness of learning in these different contexts.

  • Objectives: The purpose of this study was to evaluate the neck node metastasis pattern and related clinical factors in oral cavity cancer patients. Materials and Methods: In total, 76 patients (47 males, 29 females) with oral squamous cell carcinoma (OSCC) who had no previous malignancies and were not undergoing neoadjuvant concomitant chemoradiotherapy or radiotherapy were selected for analysis. Results: Occult metastases were found in 8 of 52 patients with clinically negative nodes (cN0, 15.4%). Neck node metastases were found in 17 patients (22.4%). There was a statistically significant relationship between neck node metastasis and T stage (P=0.014) and between neck node metastasis and distant metastasis (Fisher's exact test, P=0.019). Conclusion: Neck node metastasis was significantly related to tumor size and distant metastasis during follow-up.

  • Among the many methods to make sustainable garments, convertible garments have the potential to change style and function that allow consumers to keep and use garments longer with the possibility of enhancing sustainability. This research analyzes consumer preferences in changeable design options for convertible dresses and the consumers' influence on environmentally responsible apparel consumption (ERC) behaviors on their preferences regarding changeable design options of dresses, which are popular items. An online survey collected data from a convenient sample of 321 female college students from four universities in the United States. Data were analyzed using IBM SPSS through descriptive analysis, cluster analysis, and independent samples t-test. There were significant differences between high and low ERC groups in design preferences that considered important aspects of purchasing, using convertible dresses, and purchase intentions. Detailed differences among sub-groups were analyzed. Designers are encouraged to make tying/folding/wrapping dresses with changes of size/fit, dress length, or color/pattern. The results are beneficial for apparel designers when developing convertible dresses with the guidance of consumers' design preferences and differences according to ERC levels.

  • Purpose: The purpose of this study was to identify factors that affect care left undone among newly graduated nurses. Methods: Participants were 236 newly graduated nurses with less than 1 year of experience from 5 general hospitals in Busan. Self-report questionnaires were completed by nurses between October and November, 2016. Data were analyzed using t-test, ANOVA and multiple regression analysis with the SPSS/WIN 25.0 Program. Results: The mean score for care left undone was $2.18{\pm}1.43$. Factors influencing care left undone were monthly income and working environment. Regression analysis showed that working environment and monthly income explained 11.0% of the variance while controlling for participants' demographics and work characteristics. Conclusion: The findings suggest that better working environment and appropriate monthly income are important to reduce care left undone in hospitals. The quality of nursing and patient safety may be ensured by reducing care left undone.

  • Purpose: This study was conducted to determine the influence of ego-identity, parenting efficacy, and stress coping style on depression in mothers of toddlers. Methods: This was a cross-sectional, descriptive study. Data were collected from 164 mothers of toddlers, and analyzed using descriptive statistics, the t-test, analysis of variance, Pearson correlation coefficients, and multiple regression analysis using SPSS for Windows version 24.0. Results: The factors influencing depression in mothers of toddlers included ego-identity, economic status, and perceived health status. These variables explained 60.0% of depression in mothers of toddlers. Conclusion: Lower ego-identity was associated with more intense depression. Therefore, healthcare providers should develop intervention programs that can improve ego-identity to decrease depression among mothers of toddlers.
