PURPOSE: The purpose of this study was to measure the effects of a school safety education program based on the PRECEDE-PROCEED model for upper grade elementary students. METHODS: One hundred ten 6th-grade students sampled from an elementary school in D City were divided into the education group (n=55) and the non-education group (n=55). School safety education was provided to the education group for 8 weeks and a questionnaire survey about safety knowledge, safety practice and the frequency of safety negligence was carried out before and after the education from March 2 to July 13, 2010. RESULTS: After the application of the safety education program, the education group got a higher safety knowledge score than the non-education group (p<.001). Both the education and non-education groups showed a significantly increased safety practice score (p<.01). In the comparison of safety negligence, the education group showed lower frequency (p<.01). In addition, according to the results of ANCOVA and t-test, the school safety education program influenced safety knowledge significantly (p<.001). CONCLUSION: This result shows that a school safety education program based on PRECEDE-PROCEED can improve safety knowledge. Further studies will be required to develop continuous and systematic safety education programs.

BACKGROUND: Glucocorticoids (GC) are the most potent medications used to control airway inflammation associated with asthma. The aim of this study was to see whether alterations in GC receptor binding contribute to poor response to GC therapy in severe asthma. METHODS: Seventeen patients with severe persistent bronchial asthma were studied. Patients were classified as GC sensitive if their morning FEV1 increased >15% after a 1-week course of systemic GC (>prednisolone 40mg/day) and GC-resistant if they failed to increase >15%. GC receptor binding affinity for dexamethasone of peripheral blood mononuclear cells (PBMCs) were determined by using a radioligand binding assay and Scatchard analysis. RESULTS: There were no significant differences of age, serum IgE levels, peripheral blood eosinophils and atopic states between GC-resistant (n=10) and GC-responsive (n=7) groups. GC-resistant patients had significantly decreased GC receptor binding affinity (Kd=24.3+/-9.55) compared to the GC sensitive patients (Kd=13.5+/-1.48) and normal controls (n=6, Kd=4.24+/-1.09). CONCLUSION: These data suggest that decreased binding affinity of GC receptor is an important factor in clinical GC resistance in chronic severe asthma.

Purpose: This study aimed to examine associations among inner strength, mood status, symptom experience, and quality of life in women with lung cancer and to investigate whether inner strength has a moderating effect on these relationships. Methods: This study used a cross-sectional design to analyze 106 women with lung cancer in the National Cancer Center. A hierarchical regression analysis was conducted on the influence of quality of life. For the moderating effects, the Johnson–Neyman methods were applied using the SPSS PROCESS macro. Results: The significant factors of quality of life were inner strength, symptom experiences, total mood disturbance, accounting for 70.7% of the variance. Inner strength had a moderating effect on the relationship between total mood disturbance and quality of life. This means that when women have higher inner strength, there is a significantly less negative effect of total mood disturbance on quality of life. Conclusion Female patients with lung cancer who experienced inner strength can improve the quality of life as well as reduce the negative impact of mood status on the quality of life. Therefore, these findings support the theory of inner strength and provide nurses with an opportunity to foster the development of this theory in female cancer survivors.

PURPOSE: A pelvic organ prolapse (POP) has various pelvic symptoms, including urinary and fecal incontinence. However, the accurate prevalence and problems in South Korea are not well known. The purpose of this study was to determine the relationship of pelvic floor symptoms in patients with a POP. MATERIALS AND METHODS: Between March 2003 and March 2004, 74 consecutive patients, with over stage II POP quantification (POP-Q) staging, were enrolled. No abnormal neurological signs were detected in 66 women after evaluation. On physical examination, these 66 patients were divided into 3 groups (A=cystocele only, B=rectocele only and C=cystocele rectocele). RESULTS: The prevalence of urinary incontinence was 28.8%, and with fecal incontinence was 9.1%. The prevalence of fecal incontinence and fecal symptoms, with the exception of fecal incontinence were 28.8 and 74.2%, respectively. With regard to the stage of POP-Q, fecal incontinence (II= 25.0%, III=27.8%, IV=75.0%) and fecal symptoms (II=77.3%, III=66.7%, IV =75.0%) were observed. Each group presented with fecal incontinence (A=38.4%, B=44.4%, C=20%) and fecal symptoms (A=56.3%, B=100%, C=74.3%). CONCLUSIONS: In this study, the prevalence of urinary incontinence was 28.8%, that of fecal incontinence was 28.8% and that of both urinary and fecal incontinence was 9.1%. The mixed symptoms may cause a dilemma in relation to the formal treatment. Our study suggests urologists should be aware of coexisting fecal symptoms associated with a pelvic organ prolapse.

PURPOSE: The aim of this study was to investigate coping styles for dysmenorrhea and explore factors related with their coping styles according to different health loci of control in middle schoolers. METHODS: Data were collected by using a structured questionnaire for 572 students from three middle schools in Seoul from March 22 to April 2, 2010. The measurement included menstrual distress, coping method questionnaire and health locus of control. The data were analyzed by using t-test, ANOVA, Pearson's correlation coefficients, and multiple regression analysis. RESULTS: Middle school students used the active behavioral coping style more often than the avoidance style. There was a significant difference in means within each coping style including levels of stress, levels of health, and regular exercise. There were also significant correlations between each coping style and health locus of control. Regression analyses indicated that the health locus of control factor is the most powerful factor in each coping style. CONCLUSION: We observed that various coping methods are used for dysmenorrhea in middle school students. However, the active behavioral coping style is dominant in such a condition. Based on these results, we need to develop a health locus of control to improve coping styles for dysmenorrhea.

BACKGROUND: Nowadays, decreased physical activity is considered to be a contributor to increase the prevalence of many diseases such as obesity, coronary heart disease and so on. Many researches demonstrated that regular physical activity reduce all cause mortality. To increase the physical activities of the population, accurate estimation of the activities is needed. Actical and actigraph are confirmed as accurate tools to measure physical activities. But the target populations of the validity studies were not Asian people. Therefore, the accuracy of the accelerometers should be confirmed in Asian people. The accuracy of the tools could be different. Therefore head to head comparison study between the tools would be needed. METHODS: Thirty volunteers from the community, ages over 20 yrs, were recruited. The participants put on the two accelerometers (Actical, Actigraph) on the waists, secured with elastic belts, and performed a session of rest and three structured activities (two walking speeds, 4 km/hr and 6 km/hr, and one jogging speed, 8 km/hr). During each activity, expired respiratory gases were collected, and oxygen consumption (VO2) was measured by indirect calorimetry (Model Quark beta2(R)). The calories measured by gas analyzer and two accelerometers were compared by correlation analysis using SPSS program. RESULTS: Pearson correlation coefficient between gas analyzer and two accelerometers was calculated at three structured activities. The r in Actical was 0.747, 0.785, and 0.677, at speed of 4, 6, 8 km/hr, respectively (P<0.05), and the same measures in Actigraph was 0.617, 0.737, and 0.530 (P<0.05), respectively. Pearson correlation coefficient was also calculated between the two accelerometers, and the r was 0.881, 0.927, and 0.824, at each speed. CONCLUSION: The Actical and Actigraph are valid tools for measuring physical activities in Korean people.

BACKGROUND AND OBJECTIVE: There have been several reports suggesting close relationships bet- ween problem behavior syndrome scale and/or social competence scale and pediatric allergic disorders such as bronchial asthma and atopic dermatitis. The aim of the present study was to confirm these relationships. We compared the behavioral symptoms and social competence scale between allergic and non-allergic patient groups using Korean-Child Behavior Checklist (K- CBCL). MATERIALS AND METHOD: One hundred and seventy-one subjects(aged 4-11 years) were enro- lled in this study. Allergy patient group(N=84) was divided into 4 subgroups, according to the allergic diseases such as atopic asthma(Group 1, BA), allergic rhinitis(Group 2, AR), atopic dermatitis(Group 3, AD), and chronic urticaria(Group 4, CU). Eighty-seven non-allergic patients (Group 5, NA) included those with pediatric general disorders, except psychomotor retardation, neurologic deficit, malignancy or other chronic disorders. K-CBCL which was filled in by parents or guardian, included eight dimensions of problem behavior: withdrawal, somatic problems, anxiety/ depression, social problems, thought problems, attention problems, delinquent behavior, and aggressive behavior. The first three scales were classified as an Internalizing broadband group and the last two scales as Externalizing group. In addition, the questionnaire included social scale, school scale, and total competence scale. RESULTS: There were no significant differences in age, sex, social economic status between 5 subgroups of allergic and non-allergic patients(p>0.05). The mean problem behavior scores tended to be higher in allergic patient group, but no statistical significance was noted(p>0.05). The mean school scale, social scale, total competence scale of allergic patient group were not significantly higher than those of non-allergic patient group(p>0.05). Combined disease group with more than 2 allergic disorders showed problem behaviors compared to non-allergic group or asthma only group. Total social competence scale was lower in allergic patient group with 1-3 years of disease duration than for shorter(less than 1 year) and longer(more than 3 years) durations. CONCLUSION: Taken together, combined disease group and allergic disease group with 1-3 years of duration showed more problem behaviors and the lowest total social competence scales, respectively.

PURPOSE: The objective of this study is to observe high-resolution computed tomography (HRCT) findings of lung parenchyme in very low birth weight (VLBW) infants between the corrected age of 38-42 weeks who were treated with oxygen after birth, and to compare them to the clinical severity of bronchopulmonary dysplasia (BPD). METHODS: The lungs of fourty-four VLBW infants with gestational ages of less than 32 weeks and birth weights of less than 1,500 g who were treated with oxygen after birth were examined using HRCT taken when the corrected age was between 38-42 weeks. Common findings among the infants and the frequency of their occurrences were noted. Total CT scores obtained by the summation of air trapping and actelectasis scores and the ratio of bronchus-to-pulmonary artery diameter were used to quantitatively evaluate HRCT findings and correlate them with the clinical severity of BPD as defined by Jobe-Bancalari diagnostic criteria. RESULTS: 1) The most common findings in HRCT images of the lungs were air trapping (56%), atelectasis (70.5%), linear opacity (77%), and distortion of the bronchopulmonary bundle (65.9%). These findings were more commonly observed in infants with BPD in a mixed pattern than those without (P<0.05). However, abnormal findings were also found in HRCT images of some infants without BPD. In infants with BPD, air trapping, atelectasis and total CT scores were higher than those without BPD. Also infants with BPD had a lower bronchus-to-pulmonary artery diameter than those without BPD (P<0.05). 2) The total CT scores (r=0.799, P<0.0001) and the ratio of bronchus- to-pulmonary artery diameter (r=0.576, P<0.0001) showed a linear correlation with the clinical severity of BPD. CONCLUSION: HRCT findings in VLBW infants between the corrected age of 38-42 weeks who had been treated with oxygen after birth are useful in revealing pathologic changes in the lung parenchyme and show a good correlation with the clinical severity of BPD.
