The purpose of this study was to investigate nutrition knowledge, dietary attitude and a food habits of middle school students. The study was carried out through questionnaire. The subjects were 431 middle school students (boys 298, girls 133) in Chonbuk area. In nutrition knowledge, there were no significant differences in total scores between boys and girls. However, the girls showed higher score in knowledge of weight control than boys did (p < 0.05). In dietary attitude, there were significant differences in attitude of "balanced meal (p < 0.05)", "sufficient protein intake (p < 0.01)", "food diversity (p < 0.001)" and "overeating (p < 0.01)" between boys and girls. The boys showed better dietary attitudes than the girls did. In food habits, there were significant differences in the rate of skipping breakfast (p < 0.05), the rates of skipping dinner (p < 0.01), the frequency of snacks (p < 0.05), the type of snacks (p < 0.05) between boys and girls. The girls showed higher rates of skipping a meal and frequency of snacks than the boys did. It suggests that gender should be considered for an effective and practical nutrition education for middle school students to improve dietary attitudes and food habits.

Hemophagocytic syndrome has been identified as a benign reactive histocytic proliferation with marked hemophagocytosis and usually associated with systemic viral infection. Recently similar cases that were associated with bacteria have been described. The syndrome is clinically characterized by fever, severe constitutional symptoms, hepatosplenomegaly, lymphadenopathy and laboratory findings of pancytopenia, hemophagocytosis, abnormal liver function test and coagulopathy. The authors experienced a case of bacteria associated hemophagocytic syndrome in a 11-year old girl following Mycoplasma pneumoniae infection. The patient showed characteristic clinical features of hemophagocytic syndrome, peripheral pancytopenia and phagocytized histiocytes in bone marrow. The brief review of the literature was made.

PURPOSE: The purpose of this study was to identify the predictors of Quality of Life (QOL) among workers in public health corporations. Methods: Data were composed of 213 office workers in three public enterprise in Seoul. Data were collected from February 11 to March 20, 2007. Data were analyzed with descriptive statistics, t-test, ANOVA, Pearson correlation and stepwise multiple regression using SPSS Win 12.0 program. RESULTS: The mean QOL of the study participants was 82.60. The QOLs of the workers were significantly different according to perceived health status of workers and working hours per week. The QOL of the workers was negatively related to working hours, job stress, and depression, and positively related to the health status, self-esteem, and health promotion lifestyle (HPLS). Significant predictors of QOL were HPLS (beta .420), depression (beta -.291), self-esteem (beta .261), and hours of work per week (beta -.114), which explained 63% in the variance of QOL. CONCLUSION: These results suggest that strategies to enhance HPLS could improve the level of QOL. Further investigations of the direct relationship between QOL and health promotion program is warranted

PURPOSE: To develop an e-learning blood-borne infection control program and to evaluate the effects of the program on risk perception, knowledge, preventive health behaviors related to blood-borne infections, and satisfaction with the program by nursing student. METHODS: The program was developed through the processes of analysis, design, development, implementation, and evaluation. The pre-experimental research design involved a one group pretest-posttest design. The setting was two universities located in Daejeon, Korea. RESULTS: Using the program that was designed and developed, results for the total score of risk perception, knowledge, and preventive health behaviors in the post-test application were significantly higher than in the pre-test application (p<.05). Relevance and usefulness of the information received the highest ratings, while the system's design were demonstrated to have the lowest ratings. Those areas requiring correction were modified accordingly. CONCLUSION: Application of an e-learning blood-borne infection control program is effective, and can be expanded to other student nurses who also have a high risk of blood-borne infections.

Purpose: The purpose of this study is to identify the educational needs of virtual reality simulations that can be applied to novice nurses during the waiting period before starting work in a hospital. Methods: A convergent mixed methods was used. The survey data were collected from 230 novice nurses, and a focus group interview was conducted with 6 new nurses. The data were collected from November 2022 to January 2023. Descriptive statistics, a frequency analysis, independent t-test, and an Importance-Performance Analysis were performed using SPSS 24.0. Results: Appropriate topics for virtual reality simulation education were indicated to be medications and intravenous injections, which are high priority topics in quantitative and qualitative research. The novice nurses wanted group activity training three to four times a week for two weeks before beginning work in a hospital. They also wanted an immersive virtual reality system based on a real hospital environment. Conclusion Based on the above results, this study provides basic data for the development of a virtual reality simulation education that can improve the adaptation of novice nurses to clinical practice. A strategy was suggested to utilize the waiting time before beginning work in a hospital as educational time.

OBJECTIVES: In this study, we investigated the potential harmful effect of the exposure to silicon dioxide (SiO2) nanoparticles through in vitro toxicity assay using human bronchial epithelial cell, Beas-2B with a focus on the involvement of oxidative stress as the toxic mechanism. METHODS: SiO2-induced oxidative stress was assessed by examining formation of reactive oxygen species (ROS), the induction of superoxide dismutase (SOD) and heme oxygenase-1 (HO-1), as well as cytotoxicity effect was evaluation by cell viability. Subsequently, to understand the molecular mechanism of nanoparticle-induced oxidative stress, the involvement of oxidative stress-responding transcription factors, such as, nuclear factor-kappaB (NF-kappaB) and nuclear factor-E2-related factor-2 (Nrf-2), and mitogen-activated protein (MAP) kinase signal transduction pathway was also investigated. RESULTS: 5-d i phenyltera zolium bromide (MTT) assay results show that decrease 20% in cell viability and the number of cells in the subG1 phase increased. The increase in ROS formation was observed in SiO2 nanoparticle treated cells. The expression of SOD protein was not changed, whereas that of HO-1 was increased by SiO2 nanoparticle exposure. transcription factors Nrf-2 and the expression of phosphorylated form of extracellular signal-regulating kinase (ERK) was strongly induced by SiO2 nanoparticle exposure. CONCLUSIONS: SiO2 nanoparticles exert their toxicity through oxidative stress as they cause the significant increase ROS level. SiO2 nanoparticles induce induction of HO-1 via Nrf-2-ERK MAP kinase pathway. Our tested oxidative stress parameters are rather limited in terms of allowing the full understanding of oxidative stress and cellular response by SiO2 nanoparticle exposure.

Cases of acute myocardial infarction (AMI) that occur during pregnancy or postpartum are rarely reported. Ergot derivatives are known to induce the spasmodic contraction of coronary arteries. Administration of ergot derivatives can cause AMI, even in normal healthy people. In several reported cases, ergot derivatives triggered severe AMI during the postpartum period. Here, we report the case of a forty-year-old woman who was successfully impregnated by artificial fertilization and died after treatment with ergot derivatives. The autopsy revealed AMI with severe coronary atherosclerosis. This is the first case that reports aggravation of pre-existent severe coronary atherosclerosis after postpartum infusion of ergot derivtives.

OBJECTIVE: This study was done to explore the relationship between circadian types, depressive mood, and sleep quality and to identify the mediating effect of depression between circadian types and sleep quality in shift work nurses. METHODS: Participants were 510 females selected by convenience sampling. Data were collected from October to November 2008 using the Composite Scale for Morningness, Beck Depression Inventory, and Pittsburgh Sleep Quality Index-Korean. The data were analyzed using descriptive statistics, Pearson correlation coefficients, logistic regression and multiple regression. RESULTS: There were significant relationships between sleep quality and circadian types(r=-0.160, p<0.001), and depressive mood (r=0.438, p<0.001). In addition, the circadian types was significantly correlated with depressive mood (r=-0.236, p<0.001). Depressive mood showed mediating effect between circadian types and sleep quality (beta=0.424, p<0.001). Evening type subjects showed higher scores in depressive mood and sleep quality than morning type ones. CONCLUSION: These results suggest that depression and circadian rhythm management in nurses with evening type would contribute to the prevention of sleep disturbance.

Headaches attributed to disorders of the sinonasal region make their diagnosis and treatment sometimes challenging. Contact point between opposing mucosal surfaces in the nasal cavity can cause headache by a mechanism of referred pain in the distribution of trigeminal nerve. The most common anatomic abnormality of intranasal contact point is the diverse pattern of septal deviation in association with turbinate deformity or hypertrophy. In the absence of other pathological findings, the evaluation for intranasal contact points should be considered. We herein report that a patient, suffering from headache and periorbital pain refractory to medical treatment, experienced a complete abolition of pain after surgical correction of mucosal contact point in the nasal cavity.
