PURPOSE: The purpose of this study was to identify body esteem, body figure discrepancy and depression in women college students. METHOD: The data were collected during April and May, 2004 using a questionnaire. The participants were 364 women college students attending universities in Seoul and Gangwon-Do. RESULTS: The BMI for under weight, normal weight and overweight for the college women were 49.2%, 48.3%, 2.5% respectively. But 52.6% of the students perceived themselves as obese and only 11.5% described themselves as being 'thin'. The mean scores for BMI, body esteem, body figure discrepancy and depression were 20.11+/-2.20, 2.36+/-.79, 1.07+/-.58 and 1.20+/-.48 respectively. Significant difference was found in body esteem score (F=26.389, p<.0001) and body figure discrepancy (F=64.167, p<.0001) according to BMI scores. There were negative correlations between body esteem and body figure discrepancy (r=-.582, p=.0001), between body esteem and depression (r=-.120, p=.028), between body esteem and BMI (r=-.422, p=.0001), and a positive correlation between body figure discrepancy and BMI (r=.630, p=.0001). Factors such as body figure discrepancy, BMI and depression explained 36.7% of the variance in students' body esteem. CONCLUSION: This study suggests that an intervention program is necessary for women college students to increase their body-esteem.

PURPOSE: This study was conducted to evaluate the effectiveness of autogenic training on stress responses through a systematic review and meta-analysis. METHODS: A systematic search was conducted using eight core electronic databases (Embase, CENTRAL, Medline, CINAHL, PsycInfo, DBpia, KISS, and RISS). To estimate the effect size, a meta-analysis of the studies was performed using RevMan 5.3.5 program. RESULTS: A total 21 studies out of 950 studies were included in the review, and 11 were included for meta-analysis. These studies showed that autogenic training decreased anxiety and depression, and increased the high frequency of heart rate variability. Calculations to understand the effect of autogenic training on anxiety, through a meta-analysis, observed a reduction effect of anxiety score by 1.37 points (n=85, SMD=−1.37: 95% CI −2.07 to −0.67), in the studies on short-term intervention targeting healthy adults. On the other hand, similar calculations to understand the effect of autogenic training on depression observed, a reduction effect on the depression score by 0.29 point (n=327, SMD=−0.29: 95% CI −0.50 to −0.07), in the studies on long term intervention targeting the patient group. CONCLUSION Autogenic training is effective for adults' stress management, and nurses will be able to effectively perform autogenic training programs for workers' stress relief at the workplace.

PURPOSE: To calculate the appearance of the image distortion from metallic artifacts and to determine the location of a metallic needle from a distorted MR image. MATERIALS AND METHODS: To examine metal artifacts, an infinite metal cylinder in a strong magnetic field are assumed. The cylinder's axis leaned toward the magnetic field along some arbitrary angle. The Laplace equation for this situation was solved to investigate the magnetic field distortion, and the simulation was performed to evaluation the image artifact caused by both readout and slice-selection gradient field. Using the result of the calculation, the exact locations of the metal cylinder were calculated from acquired images. RESULTS: The distances between the center and the folded point are measured from images and calculated. Percentage errors between the measured and calculated distance were less than 5%, except for one case. CONCLUSION: The simulation was successfully performed when the metal cylinder was skewed at an arbitrary tilted angle relative to the main magnetic field. This method will make it possible to monitor and guide both biopsy and surgery with real time MRI.

BACKGROUND/OBJECTIVES: Owing to coronavirus disease 2019 (COVID-19), the shift from offline to online classes has caused significant changes in high school students' daily habits, including sleep patterns and dietary intake. This study explored the association between sleep schedule fluctuations and dietary quality among high school girls during the COVID-19 pandemic. This study examined the association between bedtime, wake-up time, and adolescent dietary quality during the weekly online/offline school period among 517 high school girls in Incheon, South Korea. SUBJECTS/METHODS: The participants were divided into 2 groups: normal sleepers (n = 244), who maintained normal sleep schedules defined as a midpoint between bedtime and wake-up time before 5:30 a.m., during in-person and online classes; and late sleepers (n = 273), who maintained a normal sleep schedule during in-person classes but exhibited late sleep patterns defined as a midpoint after 5:30 a.m., during online classes. RESULTS: Shorter sleep duration was characteristic of late sleepers with circadian rhythm disruption, who also displayed poorer dietary quality, including higher consumption of caffeinated beverages and street food and never consuming breakfast. Among the 5 constituent factors, disrupted sleep timing was associated with lower Nutrition Quotient for Adolescents scores in total, moderation, and environment. This association persisted independent of the grade level, even after adjusting for school grade. These findings highlight the significant effect of sleep patterns on dietary habits. CONCLUSION This study highlights the significant relationship between disrupted circadian rhythms and poor dietary quality among high-school girls. These findings reveal the need for interventions to promote healthy sleep patterns as a strategy to improve the dietary quality and overall health of adolescents.

BACKGROUND: This is a theory verification study in which the theory of planned behavior (TPB) of Ajzen is applied to predict operating room (OR) infection control behavior. The study was carried out to know the path of attitude, subjective norm, perceived behavioral control, and intention towards OR infection control behavior. METHODS: A total of 178 OR nurses working at 13 hospitals in Seoul were the subjects of this study. A questionnaire survey was performed; the data were collected from April 6 to April 19, 2005 and analyzed with t-test, ANOVA, multiple regression, and person's correlation using SPSS program. Using AMOS, the factors of TPB were analyzed with path analysis. RESULTS: The total mean of infection control behavior of OR nurses was 4.37 points out of possible 5.0, and asepsis/operating instrument sterilization had 4.69, which was the highest among all areas of infection control behavior. In case of the relation between attitude, subjective norm, perceived behavior control, and intention, there was the strongest relation of cause and effect (path coefficient 0.38, 39%). In case of intention, perceived behavior control, and behavior, the relation of cause and effect between intention and behavior was path coefficient 0.17 and behavior was path coefficient 0.19. The degree of explanation was 10%. CONCLUSION: We should try to improve environment management in behavior area, and through this study, the importance of education was verified.
