BACKGROUND AND OBJECTIVES: To determine the level of knowledge of stroke and heart attack (HA) symptoms and risk factors of cardiovascular disease (CVD) in rural elderly people who are at risk for CVD. SUBJECTS AND METHODS: A total of 444 adults over the age of 60 living in a rural province of Korea with at least one CVD risk factor participated in this survey. RESULTS: A total of 72.5% of the participants had hypertension and 28.4% had diabetes, whereas approximately 40% exhibited over two CVD risk factors. The mean knowledge scores for HA symptoms (4.3/9) were lower than scores for stroke symptoms (5.8/9), and the mean knowledge score for risk factors was 7.3/11. Stepwise multiple regression analyses showed that old age, low level of education, and low income level were the determining factors for low knowledge levels of stroke and HA symptoms as well as CVD risk factors. A low perceived risk of stroke or HAs also predicted a low knowledge of CVD risk factors. CONCLUSION: Community-wide public campaigns are needed, which are designed to help elderly people in rural areas with low education levels and socioeconomic status at risk for CVD to improve the awareness of stroke and HA.

PURPOSE: The purpose of this study was to verify the relationships among social support, resilience and post traumatic stress disorder (PTSD), and especially to identify factors influencing PTSD in police crime scene investigators. METHODS: A cross-sectional design was used, with a convenience sample of 226 police crime scene investigators from 7 Metropolitan Police Agencies. Data were collected through self-report questionnaires during July and August, 2015. Data were analyzed using t-test, χ2-test, Fisher's exact test, and binary logistic regression analysis with SPSS/WIN 21.0 program. RESULTS: The mean score for PTSD in police crime scene investigators was 13.69. 11 points. Of the crime scene investigators 181 (80.1%) were in the low-risk group and 45 (19.9%) in high-risk group. Social support (t=5.68, p<.001) and resilience (t=5.47, p<.001) were higher in the low-risk group compared to the high-risk group. Logistic regression analysis showed that resilience (OR=4.74, 95% CI: 1.57~14.35), and social support (OR=2.13, 95% CI: 1.23~3.69) are effect factors for PTSD low group. CONCLUSION: For effective improvement of PTSD in police crime scene investigators, intervention programs including social support and strategies to increase should be established.

PURPOSE: Leptin, the product of the ob gene is primarily by adipose tissue but also by the human placenta. Leptin may also have a role as a regulator of fetal growth and development during normal pregnancy as well as in pregnancies associated with anomalous fetal growth. Our study aimed to discover whether or not leptin concentration in neonatal cord blood correlates with maternal disorder(preeclampsia, antenatal steroid). METHODS: Seventy newborns - twenty of preeclampsia, twenty of antenatal steroid treatment, ten of diabetes mellitus, twenty of neonatal asphyxia- and their mother were enrolled in this study. Gestational age, birth weight, length and placental weight were measured. Maternal age and weight were measured. Cord blood and maternal venous samples were collected and serum was separated and stored at -70dgreesC. Leptin was measured by radioimmunoassay. RESULTS: Neonatal cord leptin concentration was significantly elevated in infants whose mothers received antenatal steroid, preeclamptic mothers and diabetic mothers Also, neonatal cord leptin concentration was correlated with maternal serum leptin concentration in those maternal disorders. Cord blood leptin concentration in neonatal asphyxia group was significantly elevated, but wasn't significantly correlated with their maternal serum leptin concentration. CONCLUSION: Neonatal cord leptin concentration was significantly increased in mothers with preeclampsia, diabetes mellitus, and exposure of the antenatal steroid. We find that maternal disorders affected leptin concentration in cord blood, and that increased cord blood leptin in neonatal asphyxia was shown to be a product of fetus.

PURPOSE: p53 gene mutations, one of the most common alterations found in human tumors, has also been detected in gastric carcinoma, and shown to have a crucial and early role in gastric carcinogenesis of intestinal type and mainly associated with tumor progression in the cancer of diffuse type. We tried to investigate the frequency of p53 mutations in 27 gastric carcinomas. MATERIALS AND METHODS: Fresh tumor tissue from a series of gastric carcinoma was screened for p53 mutations by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) with silver staining and confirmed by direct-sequencing in 27 cases of gastric carcinoma. Immunohistochemical method for p53 protein accumulation was also performed in the same cases. RESULTS: Immunohistochemistry revealed 20 of 27 cases of gastric carcinoma, positive for p53. PCR-SSCP analysis of p53 exons 5-8 detected mobility shift in 4 out of 20 p53-positive tumors; three from exon 5 and the other from exon 7, respectively. DNA sequencing of exon 5 showed CGC to CAC point mutation in one of three cases; exon 7, ATC to AAC point mutation. It seemed that there was no correlation between genetic alterations of p53 gene detected by PCR-SSCP and expression of p53 protein by immunohistochemistry. CONCLUSIOAS: Our results suggest that mutations of the p53 gene are rare genetic events in carcinogenesis of gastric carcinomas. There was discrepancy between mutations screened by PCR-SSCP and overexpressions in immunohistochemical staining.

This study analyzed the intake of calories and nutrients based on the consumption of black beans. The survey was conducted on 124 college students (male: 42, female: 82), of whom 63.7% (79 students) were consumers of black beans. The calorie intake of the black bean intake group (1599.81±555.48 kcal) was significantly higher than that of the non-black bean intake group (1259.99±507.58 kcal) (P＜0.01). The black bean intake group also showed a significantly higher intake of crude protein (P＜0.05), plant protein (P＜0.01), animal protein (P＜0.05), crude fiber (P＜0.001), plant calcium (P＜0.001), plant iron (P＜0.001), zinc (P＜0.01), vitamin B 2 (P＜0.01), vitamin C (P＜0.01), vitamin E (P＜0.01) and folic acid (P＜0.001) compared to the non-black bean intake group. There was a positive correlation between the frequency of black bean intake and crude fiber (P＜0.05), plant calcium (P＜0.05), plant iron (P＜0.05), and folic acid (P＜0.05). Overall, the black bean intake group was more likely to eat black sesame 13.82 times (95% CI=5.37, 35.55), white beans 10.79 times (95% CI=3.53, 33.02), mung beans 7.22 times (95% CI=2.58, 20.23), and brown rice 4.72 times (95% CI=1.88, 11.84), than the non-black bean intake group. In conclusion, we believe that black beans constitute a vital food ingredient that is necessary to provide Korean college students with a well-balanced diet.

Purpose: Nursing students are susceptible to medication safety incidents in the neonatal intensive care unit (NICU) related to a lack of communication experience. The purpose of the present study was to investigate the impact of a NICU medication safety simulation (NMSS) focusing on communication clarity, patient hand-off confidence, and patient safety competency in senior-year nursing students. Methods: The study utilized a nonequivalent control group pretest-posttest design. In total, 60 nursing students were assigned to two groups. The experimental group participated in the NMSS, which included three medication error scenarios. Pairs of students completed the scenarios together in 10 to 20 minutes. Data were analyzed using the chi-squared test, independent t test, and ANCOVA. Results: The experimental group showed significant improvements in communication clarity (p=.015), and patient safety competency (p<.001) compared to the control group. Using the pretest values as covariates, patient hand-off confidence scores significantly increased (p=.027). Conclusion Implementing the NMSS focusing on communication in the pediatric nursing curriculum helped students to communicate clearly and concisely about medication errors, and its use is recommended to promote patient safety competency in the NICU.

PURPOSE: The objective of this study was to analyze the factors affecting the stages of exercise behaviors changes of low back pain patients. METHODS: The participants in this study were 220 low back pain patients who have been treated by therapeutic exercise or had the exercise treatment under the doctor's advice. The tools used for this study were the stages of exercise behavior change, intrinsic motivation questionnaires, and physical activity social support scale (PASS). RESULTS: The group that did exercise (preparation stage, maintenance stage, action stage) was 75.9% but the group that did not exercise (precontemplation stage, contemplation stage) was 24.1%. Social supports from family members and friends and motivation affected the exercise behaviors changes. And 34.6% of the exercise behavior change can be explained by the social support (family, friend) and motivation. CONCLUSION: There were two recommendations for maintaining the exercise behaviors of low back pain patients based on theoretical background. First, we recommended more exercise programs which reinforce social supports from family and friend for constant exercise behaviors of low back pain patients. Second, more exercise programs for the low back pain patients who have similar health goals or problems were needed for motivating them to join the exercise programs.

PURPOSE: The purpose of this study was to investigate psychological capital, sense of community and stress in relation to school adjustment and to identify factors influencing school adjustment in middle school students. METHODS: This study population consisted of 150 middle school students. Data were analyzed using t-test, analysis of variance, Pearson correlation coefficient, and multiple regression analysis. RESULTS: The mean score for school adjustment in middle school students was 3.68 out of 5 points. School adjustment explained 34% of the variance in sense of community (β=.39, p < .001), positive psychological capital (β=.35, p < .001), academic performance (β=.26, p < .001), and stress (β=−.21, p < .001). CONCLUSION: The results of our research suggest that sense of community is an important variable influencing school adjustment in middle school students. Therefore, to promote school adjustment in middle school students, it is necessary to develop and implement active educational strategies promoting sense of community, positive psychological capital, academic perfomance, and controlling stress.
