  • The purpose of this study is to analysis eye tracking for high school students' learning styles in the process of solving in the behavioral domains of the College Scholastic Ability Test on Earth Science I. The subjects of this study were 50 students from two classes out of 4 classes in E high school in Chungcheong province. Among them, we conducted experiments by randomly sampling 2 students of each type of learning based on the criteria that they had not encountered the problem of Earth Science I from the past two years. The findings indicate that the item correctness rate of divergers, assimilators, convergers, and accommodators were higher in the knowledge domain, application domain, knowledge-understanding domain, and understanding domain. This confirms that there is a difference among the four learning styles in the level of achievement according to the behavioral areas of the assessment questions. The latter finding was that the high eye-share of AOI 2 appeared higher than AOI 1, 3, 4 in the course of solving the problems. This is because the four types of learners pay more careful attention to the AOI 2 area, which is the cue-or-information area of problem solving, that is, the Table, Figure, and Graph area. Therefore, in order to secure the fairness and objectivity of the selection, it is necessary that an equal number of questions of each behavioral domain be selected on the Earth Science I Test of the College Scholastic Ability Test in general. Besides, it seems to be necessary that the knowledge, understanding, application, and the behavior area of the inquiry be highly correlated with the AOI 2 area in development of test questions.

  • Purpose: The purpose of this study was to assess the effects of cognitive behavioral therapy (CBT) on depression, anxiety, self care behavior and quality of life in cancer patients. Methods: Two thousand and eighty three abstracts were identified through six electronic databases (1980 to June 2012) in Korea. Seventeen studies involving 679 participants met the inclusion criteria for meta analysis. Two authors independently assessed trial quality by Cochrane's Risk of Bias and Methodological Items for Non Randomized Studies and extracted data. The data were analyzed by the RevMan 5.2 program of Cochrane library. Results: Overall, study quality was moderate to high. CBT was conducted for a mean of 4.2 weeks, 7 sessions and an average of 36.1-minutes per session. CBT was effective for depression (d=-0.85; 95% CI=-1.09, -0.61), anxiety (d=-0.52; 95% CI=-0.75, -0.29), self care behavior (d=-1.34; 95% CI=-1.93, -0.74), and quality of life (d=-0.42; 95% CI=-0.80, -0.04). Publication bias was not detected as evaluated by funnel plot and Egger's test. Conclusion: CBT has small to large effects on depression, anxiety, self care and quality of life. These finding suggests that various CBT interventions can assist cancer patients in reducing emotional distress and improving self care and quality of life.

  • Objectives: Police officers may be at a greater risk for cardiovascular disease (CVD) than the general population due to their highstress occupation. This study evaluated how an educational program based on the health belief model (HBM) may protect police officers from developing CVD. Methods: In this single-group experimental study, 58 police officers in Iran participated in a 5-week intervention based on HBM principles. Outcomes included changes in scores on an HBM scale, time spent on moderate to vigorous physical activity (International Physical Activity Questionnaire), body mass index (BMI), blood lipid profile, blood glucose, and blood pressure. The intervention consisted of 5 HBM-based educational sessions. Follow-up was conducted at 3 months post-intervention. The paired t-test was used to examine differences between baseline and follow-up scores. Results: All aspects of the HBM scale improved between baseline and follow-up (p<0.05), except the cues to action subscale. Self-efficacy and preventive behaviors improved the most. BMI decreased from 26.7±2.9 kg/㎡ at baseline to 25.8±2.4 kg/㎡ at follow-up. All components of the lipid profile, including triglycerides, cholesterol, high-density lipoprotein, and low-density lipoprotein, showed significant improvements post-intervention. Blood glucose and blood pressure also decreased, but not significantly. Nearly 25% of participants who were not physically active at baseline increased their physical activity above or beyond the healthy threshold. Conclusions: A relatively brief educational intervention based on HBM principles led to a significant improvement in CVD risk factors among police officers. Further research is needed to corroborate the effectiveness of this intervention.

  • The purpose of this study was to investigate how parental childrearing behavior and children's sibling relationships are related to children's self-esteem. 440 middle class families consisting of two children and their parents were the subjects of this study. The research instruments included a childrearing behavior questionnaire, the Sibling Relationships Questionnaire (Furman & Buhrmester, 1985), and the Self-Perception Profile for Children (Harter, 1985). Analyses of the data included correlation analysis, canonical correlation, regression, stepwise multiple regression, and MANOVA with stepwise discriminant analysis as the follow-up test. The most powerful predictors of children's self-esteem were the Warmth-Acceptance of childrearing behavior and the Warmth-Closeness of sibling relationships. The self-esteem dimension was best predicted by parental childrearing behavior and by children's sibling relationships was Global Self-Worth. Behavioral Conduct was best predicted by the Rejection-Restriction factor of childrearing, and by Conflict (for boys) and Rivalry (for girls) factors of sibling relationships. Children's self-esteem was related more strongly to the Warmth-Acceptance and the Rejection-Restriction of opposite-sex parents. The effects of Permissiveness-Nonintervention were stronger in same-sex parent-child dyads. Parental childrearing behaviors accounted for boy's self-esteem better than girl's with the exception of Behavioral Conduct. Sibling relationships accounted for girl's self-esteem better than boy's. The $2{\times}2$ MANOVA revealed interaction effects of parental childrearing behaviors and sibling relationships on children's self-esteem. Two factors of Rivalry and Conflict in sibling relationships and all three factors of childrearing behaviors showed significant interaction effects, The childrearing factor of Permissiveness-Nonintervention and the sibling factor of Rivalry, which were relatively weak predictors of self-esteem when acting alone, gained power in explaining children's self-esteem within the interactional context.

  • Methamphetamine is an illicit drug that is often abused and can cause neuropsychiatric and neurotoxic damage. Repeated administration of psychostimulants such as methamphetamine induces a behavioral sensitization. According to a previous study, Bax was involved in neurotoxicity by methamphetamine, but the function of Bax in rewarding effect has not yet been elucidated. Therefore, we have studied the function of Bax in a rewarding effect model. In the present study, we treated chronic methamphetamine exposure in a Bax-deficient mouse model and examined behavioral change using a conditioned place preference (CPP) test. The CPP score in Bax knockout mice was decreased compared to that of wild-type mice. Therefore, we screened for Bax-related genes that are involved in rewarding effect using microarray technology. In order to confirm microarray data, we applied the RT-PCR method to observe relative changes of Bcl2, a pro-apoptotic family gene. As a result, using our experiment microarray, we selected genes that were associated with Bax in microarray data, and eventually selected the Tgfbr2 gene. Expression of the Tgfbr2 gene was decreased by methamphetamine in Bax knockout mice, and the gene was overexpressed in Bax wild-type mice. Additionally, we confirmed that Creb, FosB, and c-Fos were related to rewarding effect and Bax using immunohistochemistry.

  • Astragalus Membranaceus (AM) is a useful Korean herb that has been clinically prescribed for stress-related illness. The objective of the present study was to examine the anti-stress effects of AM on repeated stress-induced alterations of anxiety, learning and memory in rats. Restraint stress was administered for 14 days (2h/day) and AM (400mg/kg) given by oral administration, in the AM group, for the same period. Starting on the eighth day, the rats were tested for spatial memory on the Morris water maze test (MW) and for anxiety on the elevated plus maze (EPM). Changes of expression on immunohistochemistry were studied for cholineacetyl transferase (ChAT) and tyrosine hydroxylase (TH) in the brain. The results showed that the rats treated with AM had significantly reduced stress-induced deficits on learning and memory on the spatial memory tasks. In addition, the ChAT immunoreactivities were increased. In the EPM, treatment with AM increased the time spent in the open arms (p<0.001) compared to the control group. In addition, AM treatment also normalized increases of TH expression in the LC (p<0.001). In conclusion, administration of AM improved spatial learning and memory and reduced stress-induced anxiety. Thus, the present results suggest that AM is able to recover behavioral and neurochemical impairments induced by stress.

  • In a rapidly changing market, the companies are applying a variety of elements for promoting sales for the inflow of consumers. For the elements of sales promotion, the tendency to apply the experiential marketing that provides a positive recognition centering on the customers, and in such tendency, the consumers places the values on the experience obtained from the spatial elements of sales promotion provided by the companies. As it is reflected on the life style of consumers, the drugstores applied with the experiential marketing as a mean of sales promotion is rapidly growing in the distribution market. In this study, the elements of sales promotion was picked out and 5 types of experience such as sense, feel, think, act, relate of Bernd H. Schmitt was investigated. The spatial composition of drugstores were classified into destination, assortment, convenience and occasion, and through self experienced visual research, the experiential marketing strategy applied to drugstores and the elements of sales promotion applied with experiential marketing was analyzed. The streets of Hongik University as a strategic point of beauty, by selecting four H&B stores which were recently opened, a future direction is proposed by conducting the case analysis on the elements of sales promotion of drugstores and the spatial composition of drugstores applied with experiential marketing. In conclusion, in overall space, the behavioral experiential elements are weak. The behavioral experiential elements are a marketing that induce the intuitive behavior added with expertise and considered difficult to be maintained. Although the consumers think that the biggest value of drugstores is 'free and convenient product test' but in the other hand, they tend to think most positively about the consulting of experts. Therefore, the space emphasized with expertise should be more highlighted but such space should consider the convenience of consumers.

  • To investigate the neuroprotective effects of bovine colostrums (BC), we evaluate the ability of consuming BC after focal brain ischemia/reperfusion injury rat model to reduce serum cytokine levels and infarct volume, and improve neurological outcome. Sprague-Dawley rats were randomly divided into 4 groups; one sham operation and three experimental groups. In the experimental groups, MCA occlusion (2 h) and subsequent reperfusion (O/R) were induced with regional cerebral blood flow monitoring. One hour after MCAO/R and once daily during the experiment, the experimental group received BC while the other groups received 0.9% saline or low fat milk (LFM) orally. Seven days later, serum pro-inflammatory cytokine (IL-$1{\beta}$, IL-6, and TNF-${\alpha}$) and anti-inflammatory cytokine (IL-10) levels were assessed. Also, the infarct volume was assessed by using a computerized image analysis system. Behavioral function was also assessed using a modified neurologic severity score and corner turn test during the experiment. Rats receiving BC after focal brain I/R showed a significant reduction (-26%/-22%) in infarct volume compared to LFM/saline rats, respectively (P < 0.05). Serum IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ levels were decreased significantly in rats receiving BC compared to LFM/saline rats (P < 0.05). In behavioral tests, daily BC intake showed consistent and significant improvement of neurological deficits for 7 days after MCAO/R. BC ingestion after focal brain ischemia/reperfusion injury may prevent brain injury by reducing serum pro-inflammatory cytokine levels and brain infarct volume in a rat model.

  • Objective: The purpose of this study was to determine serum antioxidant nutrients and the relationship between serum antioxidants and risks of chronic diseases in obese Korean children Methods: Normal weight Korean school children (0=170), mean age of 11.5$\pm$1.5, and obese (body fat mass > $28\%$) children (0=176), mean age of 11.0$\pm$1.8, were recruited Fat mass ($\%$) was determnined by Bioelectrical Impedance (BEI), and body mass index (BMI) was calculated Fasting blood was collected to measure serum antioxidant nutrients, vitamin A, vitamin E and zinc. Serum lipid profiles including total cholesterol (TC), high density cholesterol (HDL) and triglyceride (TG), and blood glucose, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPI) were also determined. Differences in serum blood measurements between obese and normal children were assessed by independent t test. Pearson's correlation analysis was used to determine the relationship between variables. Results: Blood glucose, GPT, total cholesterol, and triglycerides concentrations were significantly higher among obese boys, compared to normal boys (p<005). Significantly lower concentrations of serum vitamin E, after adjustment for TG and TC, was shown in obese boys (0.26 mg/mg) and obese girls (0.31 mg/mg), compared to normal boys (0.36 mg/mg) and girls (0.38 mg/mg) (p<0.05). Fat mass ($\%$) was negatively con-elated with serum vitamin A and vitamin E. Conclusion: Obese Korean children showed insufficient serum vitamin E concentration and increased risk for diabetes, atherosclerosis, and liver disease. Since lower vitamin E concentration was negatively con-elated with atherogenic index, improved vitamin E status in children may decrease the risk of atherosclerosis later in life.
