Neuroprotective Effects of Bone Marrow Stromal Cell Transplantation in Combination With Treadmill Exercise Following Traumatic Brain Injury / 대한배뇨장애요실금학회지

PURPOSE: Traumatic brain injury (TBI) causes cognitive impairments, motor deficits, and neuropsychiatric/behavioral deficits problems. Transplantation of bone marrow stromal cells (BMSCs) facilitates functional recovery from brain insults. Treadmill exercise increases neurogenesis and inhibits apoptosis. In this study, we investigated the effects of BMSC transplantation in combination with treadmill exercise on memory function, by evaluating its effect on neurogenesis and apoptosis in the hippocampus following TBI. METHODS: TBI was induced using an electromagnetic-controlled cortical impact device. BMSCs were transplanted into both sides of traumatic scar region 1 week after TBI induction. One week after transplantation of BMSCs, the rats in the exercise groups were trained to run on a treadmill for 30 minutes once daily for 28 days. Step-down avoidance task and radial 8-arm maze test were conducted. Levels of 5-bromo-2'-deoxyuridine and caspase-3 were evaluated using immunohistochemistry. Western blot was used to evaluate the expression of brain-derived neurotrophic factor (BDNF), tyrosine kinase B (TrkB), total-extracellular signal-regulated kinase 1 and 2 (t-ERK1/2), phosphorylated-ERK1/2 (p-ERK1/2), Bcl-2, and Bax. RESULTS: TBI deteriorated memory function, suppressed neurogenesis, and accelerated apoptosis in the hippocampus. Treadmill exercise and BMSC transplantation independently improved memory function by increasing neurogenesis with suppression of apoptosis through the BDNF-ERK pathway in the TBI-induced rats. Combination of BMSC transplantation with treadmill exercise showed additional enhancement of neurogenesis and suppression of apoptosis in the hippocampus. CONCLUSIONS: The present study shows that treadmill exercise may aid the therapeutic effect of BMSC transplantation on TBI in rats.

Factors Influencing Sleep Patterns during Clinical Practice Weeks among Nursing Students : Based on Spielman's Model

PURPOSE: The purpose of this study was to identify the sleep patterns of nursing students using self-report questionnaire and physiologic measurement, to examine the factors influencing sleep patterns in based on Spielman's model. METHODS: Participants were 119 nursing students who were in the clinical practice period. Self-report questionnaires and actigraphy were used to collect the data. Data were analyzed using descriptive statistics, correlation and regression by the SPSS/WIN 21.0 programs. RESULTS: When sleep was measured by self-report questionnaire, 84 students (70.6%) showed poor sleep quality. The mean sleep efficiency was 82.6%, and 67 students(56.3%) showed low sleep efficiency (less than 85.0%). The factors affecting subjective sleep pattern measured by KMLSEQ were circadian sleep type (β=.28, ρ=.003) and alcohol (β=.20, ρ=.031). The factors affecting total sleep time were sedentary behavior (β=-.27, ρ=.003) and daytime sleepiness (β=-.33, ρ<.001). CONCLUSION: Many nursing students in their clinical practice period expressed sleep disturbance. Factors affecting the perceived sleep measured by the self-report questionnaire and objective sleep evaluated by physiologic measures were different. The evening type of students perceived poor sleep quality, however, sedentary life style and daytime sleepiness resulted in short sleep time. Therefore, more studies measuring the objective sleep characteristics are needed using subjective and objective characteristics.

Effectiveness of a Secondhand Smoking Prevention Program on Adolescents

PURPOSE: This study has examined effectiveness of a secondhand smoking prevention program for adolescents. METHODS: The study was done in a nonequivalent control group pretest/posttest design. The subjects of the current study were 198 middle school students from K city in the Gyeongbuk province. The students were assigned to an experimental group (100) and participated in the secondhand smoking prevention program or to a control group (98) and did not take part. Data collection was done from June to July 2012. A Chi-square test, independent t-test, paired t test and ANCOVA were used with the SPSS 18.0 program for data analysis. RESULTS: There were significant differences between the groups in knowledge of short-term influence of secondhand smoking (F=9.65, p<.005), knowledge of long-term influence of secondhand smoking (F=15.53, p<.001), verbal coping skills for secondhand smoking prevention (F=16.35, p<.001), behavioral coping skills for secondhand smoking prevention (F=8.49, p<.005), and assertiveness of secondhand smoking prevention (F=17.30, p<.001) measurements. CONCLUSION: The secondhand smoking prevention program delivered to the adolescents is an effective method of encouraging secondhand smoking prevention and can be utilized as an effective nursing intervention for adolescents.

Effects of Korean Proficiency and Parent-child Cohesion on Self-esteem and Acculturation among Children from Multicultural Families

PURPOSE: There is evidence that parent-child cohesion is a potentially influential factor in children's self-esteem and acculturation. However, no research to date has examined cohesion with parents as a potential pathway between Korean proficiency and self-esteem or acculturation among children from multicultural families. This study was done to address these limitations by examining whether and to what extent cohesion with parents mediated the effect of Korean proficiency on self-esteem and acculturation among children from multicultural families. METHODS: Data were collected from a sample of 138 mothers and their children living in Seoul, Daegu, Kyungi province, and Kyungpook province. Multiple regression analysis was used to examine the relationships between the variables of interest. Mediation effects of cohesion with parents were tested by following the procedure recommended by Baron and Kenny (1986). RESULTS: Cohesion with parents partially mediated the relationship between Korean proficiency and self-esteem. For children's acculturation, the effect of Korean proficiency was partially mediated through father-child cohesion. Mother-child cohesion completely mediated the relationship between Korean proficiency and acculturation. CONCLUSION: These findings suggest that to help children from multicultural families experiencing difficulties with self-esteem or acculturation, it might be useful to develop programs that are aimed at strengthen cohesion with parents.

RESULTS: There was no significant difference between small-medium hospital nurses and general hospital nurses in internal marketing and customer orientation. But nurses in small-medium hospitals had higher levels of job satisfaction than general hospital nurses. CONCLUSIONS: These findings demonstrate the necessity of developing programs that will help to improve job satisfaction in nurses.

Meta Analysis of Variables Related to Attention Deficit Hyperactivity Disorder in School-Age Children

PURPOSE: The purpose of this study was to use meta-analysis to examine recent domestic articles related to attention deficit hyperactivity disorder (ADHD) in school-age children. METHODS: After reviewing 213 articles published between 1990 and 2009 from and cited in RISS, KISS, and DBpia, the researchers identified 24 studies with 440 research variables that had appropriate data for methodological study. SPSS 17.0 program was used. The outcome variables were divided into five types: Inattention, hyperactive impulsive, intrinsic, extrinsic, and academic ability variables. RESULTS: Effects size of overall core symptoms was 0.47 which is moderate level in terms of Cohen criteria and effects size of overall negative variables related ADHD was 0.27 which is small level. The most dominant variable related to ADHD was obtained from hyperactive-impulsive (0.70). Also academic ability (0.45), inattention (0.37), and intrinsic variables (0.29) had a small effect whereas extrinsic variables (0.13) had little effect on descriptive ADHD study. CONCLUSION: The results reveal that ADHD core symptoms have moderate effect size and peripheral negative variables related ADHD have small effect size. To improve the reliability of the meta-analysis results by minimizing publication bias, more intervention studies using appropriate study designs should be done.

Relationship of Mothers' Recognition of Attention Deficit Hyperactivity Disorder (ADHD), Parenting Stress and Family Support in Children Diagnosed with ADHD

PURPOSE: The purpose of this study was to examine the relationship of mothers' recognition of Attention deficit hyperactivity disorder (ADHD), parenting stress and family support in mothers of children diagnosed with ADHD. METHODS: The data were collected from December 24, 2009 to July 23, 2010. The participants were 141 mothers of children diagnosed with ADHD and who lived in D city. Descriptive statistics, t-test, ANOVA, Pearson correlation coefficients with SPSS 17.0 were used to analyze the data. To determine the most effective variable (mothers' recognition, parenting stress and family support) to predict parental stress, data were analyzed using canonical correlation with SAS 9.1 TS. RESULTS: Canonical correlation analysis revealed that professional and teachers' roles of the 3 sub-domains of mothers' recognition were the most outstanding variables in predicting parenting stress. Parental distress/parent-child dysfunctional interaction of parenting stress was the most outstanding variable in predicting both mothers' recognition and family support. Spouse cooperation in family support was the most outstanding variable in predicting parenting stress. CONCLUSION: The results suggest that strengthening parents' recognition of ADHD and supporting interventions are important for reducing parenting stress. Professional and teachers' roles, parental distress/parent-child dysfunctional interaction and spouse cooperation should be included in the contents of structured programs.

Nursing Consideration of the Infant Care Act and Suggestion on Its Enforcement Decree and Regulations / 아동간호학회지

PURPOSE: This descriptive study was conducted to illuminate, from the nursing point of view, the infant care act, which was revised recently and to suggest a desirable direction of its enforcement decree and regulations. METHOD: This study was carried out through literature review and a collection of child care experts' opinions. RESULTS: The most remarkable changes in infant care act and the suggestions for a desirable direction of its enforcement decree and regulations are as follows: It can be said that the law on 'health', 'nutrition' and 'safety' for a child care center was improved to the level of act from the level of enforcement regulation. In the enforcement regulation on the distribution of nurses in child care centers, it is desirable that nurse's aids are excluded. It is recommended that every child care center should have a nurse or a health care manager and/or an emergency caretaker. In the curriculum for child care, the subjects on child health care should be an essential subject, not elective. CONCLUSION: Child care act should be reformed under the discipline of first priority to child health. Every nurse and nursing professor should have interest and earnestness in child care and conduct related studies.

The Effect of Sensory Stimulation on Mother-Infant Interaction in Premature Infants / 아동간호학회지

PURPOSE: This study was designed to investigate effect of sensory stimulation on the mother-infant interaction in premature infants. METHOD: The subjects of this study consisted of 36 pairs of premature infants and their mothers from NICU of one university hospital located in Taegu, 18 pairs for intervention group and 18 pairs for control group. The data were collected from May, 1999 to October, 2000. For the intervention group Field's sensory stimulation(tactile and kinesthetic stimulation) was applied 2 times a day for 10 days(10:00-11:00 in the morning and 7:00-8:00 in the afternoon by researcher and mother). To determine mother and infant interaction during feeding, tool developed by Kim Mi-Ye(1999) was used. Collected data were analyzed with SAS program using chi-square test and t-test. RESULT: Significant differences were found in mother-infant interaction between two groups(t=-5.38, p=.00). It indicates that sensory stimulation was effective in improving mother-infant interaction. In the aspects of the quality of mother-infant interaction, sensory stimulation was most effective in improving sensitivity to mother and infant's synchronic behaviors(t=-5.43. p=.00) and followed by growth fostering(t=-5.07, p=.00), sensitivity to infant's cues(t=-4.53, p=.00), clarity of infant's cues(t=-3.03, p=.00) and responsiveness to the mother's behaviors(t=-2.14, p= 0.04). CONCLUSION: Based on the result of this study, it is suggested that maternally administered sensory stimulation should be applied clinical practice to improve interaction of premature infants and their mothers.

Effects of the Nursing Intervention on Mother-Infant Interaction / 간호학회지

Mother and infant relationship has a great influence on child's developments. In this study, nursing intervention to increase maternal sensitivity to the infant's cues was applied to 25 primiparas (Experimental Group). Mother and infant interacations of these primiparas were compared with those of 25 primiparas (Control Group) who did not receive the nursing intervention. Fifty primiparas and infants were recruited from a university hospital, a general hospital, and an OBGY clinic located in Taegu city. Mother and infant interactions were assessed at 6 weeks after birth using videotapes. Feeding situations were videotaped and two trained observers analyzed the tapes. Data were collected from March 23rd to July 27th of 1998. Mother and infant interactions during feeding were assessed by the response rating scale which was modified by the author based on NCAST feeding scale (Barnard, 1978a) and AMIS scale (Price, 1983). The validity of the modified rating scale was verified by faculty members and researchers who previously had research experience in the area. Cronbach's Alpha of the modified scale for this study was .90. The data was analyzed by SAS program, using wilcoxon rank sums test, chi square test, Fisher's exact test, and ANOVA. Findings were as follows: 1. Mothers in the experimental group were more likely to have higher scores in mother and infant interactions during feeding than mothers in the control group. 2. Mothers in the experimental group showed better sensitivity to infant's signals or cues, provided growth fostering, and had higher responsibility to the infant's distress than mothers in the control group. 3. Infants in the experimental group showed higher clarity of cues and responsibility to the mother's behaviors than infants in the control group. 4. Mothers and infants in the experimental group showed higher synchronic responses than mothers and infants in the control group. In conclusion, this study has shown that the applied nursing intervention promoted mother and infant interaction among primiparas. Therefore, this study suggests that the nursing interventions to increase maternal sensitivity to the infant's cues should be broadly applied to primiparas, which can be beneficial to the social, affective, and cognitive developments of their children.
