PURPOSE: Cancer continues to be a life-threatening disease and is a preventable disease. To improve cancer preventive behaviors is important to control cancer among older rural adults who are isolated from major health care services. The purpose of this study was to identify the degrees of health literacy, cancer knowledge, and cancer preventive behaviors and to explore the impact of health literacy and cancer knowledge on cancer preventive behaviors among older rural adults. METHODS: A cross-sectional correlational study was used to examine a total of 95 older community-dwelling adults. Data were collected between June and October, 2016 with a convenience sample in rural areas located in U city. RESULTS: Multiple regression analysis revealed that 33.7% of the variance in cancer preventive behaviors was explained by health literacy and cancer knowledge. Health literacy and cancer knowledge were significant predictors of cancer preventive behaviors. CONCLUSION: Among older rural adults, inadequate health literacy and low cancer knowledge predicted lower cancer preventive behaviors. A better understanding about older rural adults with poor health literacy and cancer knowledge could facilitate the development of intervention strategies to reduce health inequalities.

PURPOSE: To evaluate the accuracy of predicting refractive outcomes of swept-source optical coherence tomography based biometry (ARGOS; Movu Inc., Santa Clara, CA, USA) in nuclear cataracts. METHODS: A total of 107 eyes (107 nuclear cataract patients) were analyzed. Subjects were divided into three groups according to the maximum nuclear density of Pentacam HR (A, lower tertile; B, medium tertile; C, upper tertile). The keratometry and axial length measured by IOLMaster (Carl Zeiss Meditec, Jena, Germany) and ARGOS systems were compared for each group. The correlation between maximum nuclear density and axial length difference readings from the two instruments was evaluated. The mean absolute error between the predicted refraction and 2-month post-operative refraction was compared. RESULTS: The maximum nuclear densities were 28.31 ± 7.30, 51.37 ± 7.82, and 88.63 ± 11.23 for groups A, B, and C, respectively. The axial length measured by ARGOS was significantly longer than that obtained using IOLMaster for groups B and C (respectively, p = 0.035, p < 0.001). A significantly positive correlation was found between the maximum nuclear density and axial length difference of the two devices (p < 0.001). Mean absolute errors were not significantly different between IOLMaster and ARGOS in group A. However, in groups B and C, the mean absolute error using ARGOS (0.31 ± 0.22 D and 0.32 ± 0.20 D, respectively) was significantly lower than that of IOLMaster (0.43 ± 0.21 D and 0.50 ± 0.26 D, respectively) (Group B, p = 0.027; Group C, p = 0.001). CONCLUSIONS: Even in dense nuclear cataracts, accurate refractive outcome prediction was possible using swept-source optical coherence tomography based biometry.

PURPOSE: The goal of this study was to examine the association between perceived racial discrimination and substance use and the potential moderating effect of perceived parental affection between the two variables. METHODS: A total of 101 Korean American adolescents participated in this cross-sectional study utilized an online survey. Descriptive statistics were used to describe for means and frequencies and the patterns of substance use. Logistic regression analysis was also used to examine the association between perceived discrimination and substance use. RESULTS: Ninety percent of the participants reported perceiving racial discrimination, and 21% had used at least one kind of substance in the month prior to taking the survey. The most frequently used substance was alcohol, followed by marijuana and tobacco products. Logistic regression analysis revealed a link between perceived racial discrimination and substance use (OR = 1.74, 95% CI = 1.01, 3.00). However, parental affection did not moderate between racial discrimination and substance use. CONCLUSION: These findings suggest that perceived racial discrimination is positively associated with substance use among Korean American adolescents, and health care providers, counselors, and school nurses should screen for discrimination-related stress and substance use in this population.

Purpose: The homelessness problem in Korea has developed into a social structural and economic problem, as the number of homeless people continues to increase. The purpose of this study is to verify the effect of self-reliance on the homeless by applying group logotherapy. Methods: This study used a Nonequivalent control group pretest‐ posttest design. 74 participants were used for analysis. Intervention group, 37 homeless people participated in the logotherapy for 5 weeks, and the effect was measured through pre, post, and 4 weeks follow-up tests. The research results were analyzed using a Repeated measure ANCOVA. Results: As a result, the difference in intervention variables according to the interaction between time * groups was significant. The meaning in life and self efficacy significantly increased in the intervention group than in the control group, and depression significantly decreased. Conclusion As a result, it can be seen that the logotherapy program is effective in increasing the meaning in life and self efficacy of homeless people's lives and reducing depression. Based on the results of this study, it is expected that the group logotherapy program will be actively used as a program for self‐reliance of the homeless person.

Purpose: : This study aimed to assess the effectiveness of an advanced practice nurse (APN)-driven ventilator weaning protocol for patients undergoing cardiac surgeries. Methods: : A retrospective analysis was conducted on 226 patients admitted to the intensive care unit (ICU) of a tertiary hospital between January and June 2020, following a cardiac surgery. Patients were divided into an APN protocol-applied group (experimental group, n=152) and a control group managed based on doctors' judgment (n=74). Ventilator weaning criteria and clinical outcomes, including duration of ventilation, length of ICU stay, and rate of reintubation, were compared between the two groups. Results: : Patients in the control group were older and had a higher incidence of massive bleeding from chest tube drainage (＞100 cc/hr) at baseline. The average duration of ventilation was significantly shorter in the experimental group compared to the control group (7.44 vs. 21.61 hours, p ＜.001). Furthermore, the mean length of ICU stay was shorter in the experimental group compared to the control group (47.96 vs. 77.97 hours, p ＜.001). There was no difference in the rate of reintubation between the two groups. Conclusion : These findings suggest that an APN-driven ventilator weaning protocol can improve clinical outcomes without significant complications. These results support the adoption of APN-driven mechanical ventilator weaning protocols in clinical practice.

PURPOSE: There is evidence supporting the concept of tumor progression from pulmonary adenocarcinoma in situ (formerly bronchioloalveolar carcinoma, BAC) to adenocarcinoma with varying degrees of invasion. The aim of this study was to investigate the role of transforming growth factor beta1 (TGFbeta1) in tumor invasiveness in lung adenocarcinoma, and to determine the potential relationships between its expression and immunophenotypes of cell adhesion molecules. MATERIALS AND METHODS: Tumor samples from adenocarcinoma in situ (n=13), minimally invasive adenocarcinoma (formerly BAC with < or =5 mm invasion, n=2), and lepidic predominant invasive adenocarcinoma (formerly mixed adenocarcinoma showing non-mucinous BAC features with >5 mm invasion, n=25) were examined for the expression of TGFbeta1, E-cadherin, N-cadherin, and H-cadherin proteins using immunohistochemistry. RESULTS: Of a total of 40 cases, 25 (63%) were positive for TGFbeta1. The frequency of immunoreactivity in patients with adenocarcinoma in situ, minimally invasive adenocarcinoma, and lepidic predominant invasive adenocarcinoma was 23% (3/13), 50% (1/2), and 84% (21/25), respectively (p=0.001). TGFbeta1 correlated with T classification (p=0.006) and stage (p=0.001). Loss of E-cadherin expression was more frequently observed in invasive adenocarcinomas than in adenocarcinomas in situ (p=0.034). E-cadherin expression inversely correlated with T classification (p=0.009). TGFbeta1 expression showed a statistically significant correlation with H-cadherin expression (p=0.040), but not with E-cadherin expression (p=0.752). CONCLUSION: These results suggest that TGFbeta1 and E-cadherin may play an important role in invasive progression of lung adenocarcinoma through regulating epithelial-to-mesenchymal transition.

OBJECTIVE: The aims of this study were to investigate a simple method for assessing anterior-posterior jaw relationships via cone-beam computed tomography (CBCT) images taken in the natural head position (NHP) relative to the nasion true vertical plane (NTVP), and measure normative data in Korean adults with normal profiles. METHODS: Subjects were selected from patients presenting for third molar extraction and evaluated as having normal profiles by three examiners. The CBCT images of 80 subjects (39 males, 41 females) were taken in the NHP according to Solow and Tallgren's method. Linear measurements of the A-point, B-point, and Pog were calculated relative to the NTVP. Student's t-test was used to assess sexual differences in these measurements. RESULTS: The mean linear measurements of the A-point, B-point, and Pog relative to the NTVP were 0.18 mm (standard deviation [SD], 4.77 mm), -4.00 mm (SD, 6.62 mm), and -2.49 mm (SD, 7.14 mm) respectively in Korean males, and 1.48 mm (SD, 4.21 mm), -4.07 mm (SD, 6.70 mm) and -2.91 mm (SD, 7.25 mm) in Korean females respectively. There were no statistically significant differences between Korean males and females (p < 0.05). CONCLUSIONS: Three-dimensional CBCT analysis using the NTVP is a simple and reliable method for assessing anterior-posterior skeletal relationships.

PURPOSE: This study was conducted to comprehensively investigate nursing students' experience of their first encounter with death of a patient during clinical practice. METHODS: This study took place from January 27 through March 6, 2012 with eight female senior nursing students enrolled at Pusan National University located in Y city who have experienced patient death. We collected their experience of their first death encounter during their clinical rotation by asking, "What is your first experience of patient's death during the clinical practice?" Husserl's phenomenological approach was applied in this study. RESULTS: In this study, 17 themes, 15 clusters of themes and eight categories were derived. The categories included "Desire to avoid the reality of death", "Powerlessness", "Anticipation for recovery shifted to fear of death", "Various interpretations of death", "Limitations in their nursing practice", "Resentment of lack of nurses", "Longing to better understand death", and "Motivation for inner growth". CONCLUSION: Through their first encounter with death of a patient, nursing students experienced various emotions and viewed their role as hospice caregiver by projecting themselves as fully trained nurses in future. Participants considered terminal care as a part of nursing care. The result of this study indicates the need to include education of death in the nursing school curriculum.

PURPOSE: To assess the degree of agreement of two rotating Scheimpflug cameras, Galilei G6 and Pentacam HR, in measuring corneal refractive power (K), anterior chamber depth (ACD), and central corneal thickness (CCT). METHODS: Measurement agreement was assessed in 40 eyes of 40 outpatients at our hospital. Measurements of anterior and posterior corneal refractive power (K), ACD, and CCT were compared between the Galilei G6 and Pentacam HR. RESULTS: For Galilei G6 (4 mm), Pentacam HR (3 mm) and Pentacam HR (4 mm), the anterior corneal refractive powers (K) were 44.35 ± 1.38 D, 44.09 ± 1.32 D, and 44.12 ± 1.35 D, respectively, and the posterior corneal refractive powers (K) were 6.39 ± 0.23 D, 6.45 ± 0.23 D, 6.45 ± 0.22 D. The differences in the results were statistically significant. The average ACD measurements using Galilei G6 and Pentacam HR were 3.26 ± 0.42 mm and 3.17 ± 0.42 mm, respectively, and the average CCT measurements were 556.65 ± 30.12 µm and 553.78 ± 29.42 µm. The differences in the measurements were statistically significant. In addition, ACD 95% limits of agreement (LoA) between Galilei G6 and Pentacam HR were in the range of -0.14~0.32 mm, and CCT 95% LoA were in the range of -12.54~18.29 µm. CONCLUSIONS: There were significant differences in measurements of anterior and posterior corneal refractive power (K), ACD, and CCT between the two cameras. Agreement analysis suggests that Galilei G6 and Pentacam HR should not be used interchangeably.
