  • Purpose : To compare the arterial and venous detection sites of triggering methods in contrast-enhanced-MR-venography (CE-MRV) for the evaluation of intracranial venous system. Materials and Methods: 41 healthy patients underwent CE-MRV with autotriggering at either the cavernous segment of internal carotid artery with an inserted time-delay of 6 seconds (n = 20) or the superior sagittal sinus without any timedelay (n = 21). 0.1 mmol/kg gadolinium-based contrast material ($Magnevist^{(R)}$, Schering, Germany) was intravenously injected by hand injection. A sagittal fast-spoiled-gradient-echo-sequence ranging from one ear to the other was performed (TR/TE5.2/1.5, Matrix $310{\times}310$, 124 sections in the 15-cm-thick volume). 17 predefined venous structures were evaluated on all venograms by two neuroradiologists and defined as completely visible, partially visible, or none visible. Results: The rate of completely visible structures were 272 out of 323 (84%) in the arterial triggering CE-MRV and 310 out of 340 (91%) in the venous triggering CE-MRV. The venous triggering CE-MRV demonstrated an overall superior visualization of the cerebral veins than the arterial triggering CE-MRV (Fisher exact test, p < 0.006). Conclusion: CE-MRV using venous autotriggering method provides higher-quality images of the intracranial venous structures compared to that of arterial.

  • Purpose: This study was conducted to test the effects of a community health promotion project for farmers cultivating garlic. Bandura's self-efficacy theory (1986) and Chaskin's community capacity framework (2001) were used as the theoretical framework. Methods: A nonequivalent control group pretest-posttest design was used. Study participants were 72 garlic farmers (intervention: 36, control: 36). The community health promotion project consisted of health promotion program and community capacity building strategies and was provided for 12 weeks (8 during farming off-season and 4 during farming season). Data were collected between February 23 and May 31, 2009 and were analyzed using chi-square test, Fisher's exact test, t-test, and repeated measure ANOVA using SPSS/WIN 12.0. Results: For the experimental group, significant improvement was found for self-efficacy, farming related health behavior, physical fitness (muscle strength, muscle endurance, upper body flexibility, lower body flexibility, cardiovascular endurance, balance, agility), farmer's syndrome, and health related quality of life as compared to the control group. Conclusion: The findings of the study indicate that the community health promotion project for garlic farmers is effective and can be recommended as a nursing intervention for health promotion of garlic cultivating farmers.

  • BACKGROUND/OBJECTIVES: This study aimed to assess the dietary behaviors of preschool children using the nutrition quotient for preschoolers (NQ-P) and analyzed the difference in the scores of the children's dietary behaviors in regards to the parents' health consciousness. SUBJECTS/METHODS: The subjects were 257 children aged 3-5 years and their parents residing in Seoul and Gyeonggi-do, South Korea. The questionnaire is composed of demographic characteristics, the NQ-P questions, and health consciousness. All data were statistically analyzed by SPSS program (ver. 25.0) and the statistical differences in variables were evaluated by χ2 test, Fisher's exact test, t-test, 1-way analysis of variance and Tukey's multiple comparison test. RESULTS: There was a significant difference on the intake frequency of processed meat by region and fast foods by age, region, and weight status (P < 0.05). There was also a significant difference in not moving around while eating by weight status and parents' effort to have healthy eating habits by sex (P < 0.05). The mean score of NQ-P of the total subjects was 59.47, which was within the medium-low grade. The mean score of balance was 61.62, and the boys were significantly higher than girls (P < 0.05). As the age of children increased, the mean score of the moderation was significantly decreased (P < 0.05). The scores of NQ-P (P < 0.05), balance (P < 0.01), and environment (P < 0.05) were significantly higher in the high group of parents' health consciousness than the low group. CONCLUSIONS: According to the results of the evaluation by NQ-P, the dietary behaviors of preschoolers residing in Seoul and Gyeonggi-do need to be improved. For improving their eating behavior and nutritional health status, parents and children need customized nutrition education programs based on sex, age, region and weight status of preschool children as well as the degree of parents' health consciousness.

  • Objective: This study aimed to compare therapeutic efficacy and technical outcomes between adjustable electrode (AE) and conventional fixed electrode (FE) for radiofrequency ablation (RFA) of benign thyroid nodules. Materials and Methods: Between 2013 and 2021, RFA was performed on histologically proven benign thyroid nodules. For the AE method, AE length ≥ 1 cm with higher power and < 1 cm with lower power were utilized for ablating feeding vessels and nodules, especially those near anatomical structures, respectively. The therapeutic efficacy (volume reduction rate [VRR], complication rate, and regrowth rate) and technical outcomes (total energy delivery, ablated volume/energy, RFA time, and ablated volume/time) of FE and AE were compared. Continuous parameters were compared using a two-sample t-test or Mann-Whitney U test, and categorical parameters were compared using a chi-squared test or Fisher's exact test. Results: A total of 182 nodules (FE: 92 vs. AE: 90) in 173 patients (mean age ± standard deviation, 47.0 ± 14.7 years; female, 90.8% [157/173]; median follow-up, 726 days [interquartile range, 441-1075 days]) were analyzed. The therapeutic efficacy was comparable, whereas technical outcomes were more favorable for AE. Both electrodes demonstrated comparable overall median VRR (FE: 92.4% vs. AE: 84.9%, P = 0.240) without immediate major complications. Overall regrowth rates were comparable between the two groups (FE: 2.2% [2/90] vs. AE: 1.1% [1/90], P > 0.99). AE demonstrated a shorter median RFA time (FE: 811 vs. AE: 627 seconds, P = 0.009). Both delivered comparable median energy (FE: 42.8 vs. AE: 29.2 kJ, P = 0.069), but AE demonstrated higher median ablated volume/energy and median ablated volume/time (FE: 0.2 vs. AE: 0.3 cc/kJ, P < 0.001; and FE: 0.7 vs. AE: 1.0 cc/min, P < 0.001, respectively). Conclusion: Therapeutic efficacy between FE and AE was comparable. AE demonstrated better technical outcomes than FE in terms of RFA time, ablated volume/energy, and ablated volume/time.

  • Purpose: The purpose of this study was to investigate the effects of a delirium prevention intervention for patients in neurology and neurosurgery intensive care units (ICUs). Methods: This study was a quasi-experimental study. Participants were 87 patients. The experimental group was provided with nonpharmacologic and multicomponent delirium prevention interventions, consisting of regular delirium assessment, improvement in orientation, early therapeutic intervention, and environmental interventions. The control group was provided with routine intensive care. Data were analyzed using $x^2$ test, Fisher's exact test, and t-test. Results: Both groups were homogeneous. The incidence of delirium and length of hospitalization were significantly lower in the experimental group compared to the control group. ICU stay, mortality and unplanned extubation were lower in the experimental group compared to the control group, but there was no significant difference. Conclusion: Findings indicate that the delirium prevention intervention is effective in reducing incidence of delirium and length of hospitalization. Therefore, this intervention should be helpful in preventing delirium in neurology and neurosurgery ICUs and can be used as a guide in the prevention of delirium in neurological diseases's patients.

  • Purpose: This study aimed to identify the effect of warm scarf on xerostomia and sore throat in postoperative colon cancer patients. Methods: A total of 40 participants with colon cancer who underwent colon cancer operation over 2hours were included from C University hospital in Seoul. The number of experimental group and control group is each 20 calculated by G*Power, and they were assigned by using nonequivalent control group no-synchronized design. In the experimental group, a warm scarf was applied to the neck for 120 minutes from entering the recovery room after the colorectal cancer surgery was completed. In the experimental group and the control group, xerostomia and sore throat were measured twice at 60-minute intervals. The degree of xerostomia was measured through the degree of wetness of the absorbent paper in mm, and the degree of sore throat was measured through the NRS (Numeral Rating Scale). Data were collected using self-administered questionnaires from August 2018 to September 2020 and were analyzed using IBM SPSS/WIN 21.0 Descriptive statistics, x2 test, Fisher's exact test, t-test were used to determine the participant's characteristics. The effect of warm scarf on xerostomia and sore throat were separately estimated by Repeated Measures ANOVA. Results: The experimental group showed significant decrease of xerostomia and sore throat as time goes (p<.001). Conclusion: Results indicate that warm scarf on xerostomia and sore throat in postoperative colon cancer patients is helpful method for relieving side effect of tracheal intubation.

  • Purpose: The purpose of this study is to investigate fatigue and its related factors in cancer patients receiving radiotherapy. Method: The subjects of this study consisted of 98 patients receiving radiotherapy. Subjects were recruited from C University Hospital radiation oncology unit located in Gwangju from March to May, 2001. Questionnaire and medical records were used for data collection. The obtained data was analyzed using SAS program that included descriptive statistics, t-test, ANOVA, Post-hoc test(Fisher's LSD) and Pearson's correlation coefficients. Result: The fatigue perceived by the subjects was middle level ($5.59{\pm}1.59$) and 72.4% of them reported greater than 5 points. The subjects in no religion, low income, and spouse caregiver groups experienced the higher fatigue than another groups, respectively. The subjects in nasopharyngeal cancer, head & neck radiation site, and analgesics medication groups did, experience fatigue as well. The fatigue not only positively correlated with symptom distress, disruption of usual activity, sleep dissatisfaction, and mood state, but also negatively with less family support. Conclusion: Cancer patients receiving radiotherapy experience the middle level of fatigue and it correlates with the multi-dimensional factors. However, further research is needed to identify the changes in fatigue over the radiotherapy period through longitudinal design and to develop nursing intervention for fatigue decrease.
