  • Purpose: This study aimed to analyse female academician health beliefs for breast cancer screening and levels of self-esteem. Materials and Methods: This cross-sectional study was conducted between October 2010 and March 2011, covering female academicians working in all faculties and vocational schools at Ondokuz Mayis University, except for the ones in the field of health (n=141). Data was collected using a questionnaire developed by researchers in the light of the related literature, the Champion's Health Belief Model Scale for Breast Cancer, and the Coopersmith Self-Esteem Inventory. Descriptive statistics, the t-test, Mann-Whitney U and correlation analysis were used to analyze the data with the SPSS 13.0 statistical package. Results: 53.8% of the participants were single, 58.6% did not have children, 80.7% had regular menstrual cycles, 28.3% was taking birth control pills, 17.9% were undergoing hormone therapy, 11% suffered breast problems, 8.3% had relatives with breast cancer, 78,6% knew about breast self-examination (BSE), 68.3% was performing BSE, 16.2% were performing BSE monthly, 17.9% had had mammograms, and 30.3% had undergone breast examinations conductedby physicians. The women who had breast physical examinations done by physicians had higher susceptibility, self-efficacy and health motivation, and fewer barriers to mammography than those who did not have breast physical examinations. Conclusions: There was a relationship between the female academician self-esteem and their perceived seriousness of breast cancer, perceived barriers to BSE and health motivation. Our Turksih female academicians had medium levels of self-esteem.

  • Background: Although previously studies have reported that most patients with malignancy prefer to die at home, this is not the real situation in clinical practice. Aim: In this study, we aimed to determine the characteristics of Turkish cancer patients admitted to the emergency department (ED) within one month before death. Materials and Method: This descriptive retrospective study focused on questions about how often and why patients with cancer visited the ED before death. A total of 107 individuals with cancer were divided into 2 groups: Group 1, patients with at least one visit in the final 4 weeks; and Group 2, patients with no visit to ED. Demographic and clinical features were compared between the two groups. Statistical analyses: Descriptive statistical methods, statistical analysis for correlation, Student's t-test, chi-square tests and logistic regression were used. Results: At least one visit to ED within one month before death was reported for 64 (60%) of the 107 cases. Of these 64 (Group 1), 38% (n=24) were discharged and 9% (n=6) died in the ED. The most common site of the primary tumor was the lung (n=24, 38%) and the most common symptom was dyspnea (92%). With the other 43 (40%) cancer patients not presenting to the ED within one month before death, they were more likely to be female with another type of cancer. Conclusions: Guidelines are needed for better management of cancer patients benefiting from visits to ED within the last month of life.

  • Background: Globally, cervical cancer is a major public health concern. Cervical cancer is the second most common cancer among women, resulting in approximately 500,000 cases per year. The purpose of this study is to compare disease characteristics between Black Hispanic (BH) and Black non-Hispanic (BNH) women in the US. Materials and Methods: We used stratified random sampling to select cervical cancer patient records from the SEER database (1973-2009). We used Chi-square and independent samples t-test to examine differences in proportions and means. Results: The sample included 2,000 cervical cancer cases of Black non-Hispanic and 91 Black Hispanic women. There were statistically significant differences between black Hispanic and black non- Hispanics in mean age at diagnosis (p<0.001), mean survival time (p<0.001), marital status (p<0.001), primary site of cancer (p<0.001); lymph node involvement (p<0.001); grading and differentiation (p<0.0001); and tumor behavior (p<0.001). Black women were more likely to develop cervical cancer and to have the highest mortality rates from the disease. Conclusions: Findings from this study show clear racial and ethnic disparities in cervical cancer incidence and prognosis that should be addressed.

  • The purposes of this study were to compare pelvic tilt before and after manipulation of sacroiliac joint in 31 low back pain patients (11 males, 20 females) with sacroiliac joint dysfunction. The sacroiliac joint of patients was manipulated on the side of anterior pelvic tilt, using the technique described by Stoddard (1962) and Greenmann (1996). I used this technique because it usually eliminated sacroiliac joint dysfunction in one treatment session. SPSS for window computer system was used to analyze the data. Also t-test was performed for comparison of pelvic tilt angle before and after manipulation, and Pearson product-moment correlation analysis was performed for intratester reliability for measurements of pelvic tilt angle before and after manipulation. The result were as follows: 1. Intratester reliability was good for measures of pelvic tilt (r=.98). 2. The pelvic tilt after manipulation was significantly decreased (mean=$3.40^{\circ}$) compared with the pelvic tilt before manipulation (p=.001). All subjects showed asymmetrical right versus left pelvic tilt before manipulation. 40% of subjects showed decreased asymmetrical right versus left pelvic tilt after manipulation, and 60% of subjects showed symmetrical right versus left pelvic tilt after manipulation. I think that pelvic tilt asymmetry with hypomobility due to loss of joint play could be symmetrized by manipulation or mobilization, but pelvic tilt asymmetry with unilateral pelvic muscle shortening could not be symmetrized by manipulation or mobilization without relaxation and stretching of shortened muscles.

  • In this research, it is empirically tested whether firm value after the adoption of IFRS is increased in Korea and China using Tobin's Q model. In Korea, IFRS was mandatorily adopted in 2011 for all companies. China mandated IFRS conversion for public traded companies starting 2007. The revisions bring Chinese standards closer to the IFRS benchmark of internationally recognized quality, but the new standards will not be word-for-word translations of IFRS, though they founded on similar principle. We expect the different adoption process between Korea and China can make different impact of IFRS on firm value. The results are summarized as follows. First, Tobin's Q seems to be increased after the adoption of IFRS, and the firm value is significantly different between before and after IFRS adoption in Korea. Second, Tobin's Q seems to be increased after the adoption of IFRS, but the analysis by t-test is not significantly higher for post IFRS. These results could be a good finding in that the impact of IFRS adoption on firm value is different by adoption process.

  • This study examined the effects of a 4 week, 8 session LCSI programs on the self-efficacy, adjustment to college of undergraduates. The number of participants was 39 students at one region. For statistical analysis, descriptive statistics, paired t-test, and Pearson correlation were used with SPSS WIN 18.0. The results are summarized as follows. The self-efficacy and underlying factors of self-efficacy in self-confidence, sense of self-regulated, task difficulty increased significantly, and the underlying factors of adjustment to college life academically, socially, emotionally, physically, love of the university, and adjustment to college increased significantly. Therefore, the self-growth program using LCSI, self-efficacy and adjustment to college life appears to have significant effects, and the LCSI program is more useful to consider the characteristics of each person by applying a range of situations to plan and deliver, such as communication or subjects, and conflict management in a variety of situations.

  • The study will furnish university students-oriented accessary market with preliminary data by virtue of university students' wearing accessary conditions. It conducted by 151 university students in Jeon-Nam and Jeon-Buk during october through november, 2014. The questionnaire is composed of 17 questions and used 151 out of 152 copies as the final data, except for one insufficient reply. The analysis method carried out a technological statistics such as frequency count, percentage, average and t-test for every questions, used by SPSS 20.0. The investigation result is as follows; The overall numbers of answerers were 151 people, 36 male and 115 female, and showed that they purchase accessaries of less than 20,000won in a jewelry shop. According to the 86.1% of university students' answers, the most well known brand is OST and then Metrocity(76.2%), Swarovski(68.9%) came after. The most visit count is to a jewelry shop, once or twice in a month, on-line shopping malls and department stores came after. Rings and bracelets are purchased once or twice in a month, and earrings are mainly put on. When purchasing accessaries, quality and scarcity design are the most significant conditions, getting the information through internet and fashion magazines. The ground of purchasing accessaries is for self-contentment and for coordinating with their fashion, and also the difficult maintenance as well as untangled wool are defined as uneasiness of using accessaries. Furthermore, the original goods are preferred for rings and necklaces, unlike earrings and bracelets.

  • The purpose of this study was to evaluate the effect of aquatic exercise on body composition, fitness and pulmonary function. Subjects were seven spasticity cerebral palsy(18-20years). The aquatic exercise program consisted of 11 items, and performed for 30-40mins in a bout, 4 times a week at the intensity of HRmax($40-65\%$) for 12 weeks. And the change of body weight, %fat, fat mass, hand grip, sit up, sit and reach, close eyes foot balance and side step have been measured before and post exercise 12 weeks. Paired t-test was performed for data analysis at the 0.051eve1 of significance. The following results as; First, body compositions(body weight, $\%$fat and fat mass) were decreased significantly after 12 weeks(p< .05). Second, muscle endurance, balance and flexibility were increased significantly after 12 weeks(p< .05, p< .01), respectively. Third, vital capacity was increased significantly after 12 weeks(p< .05). These results suggest that the aquatic exercise programs are applicable to the spasticity cerebral palsy with abnormal movement.

  • 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.

  • This study was carried out to investigate the effects of pyroligneous acid on turfgrass growth and to propose usage for sustainable management on Korean golf course green. Each plot was treated with 0, 300, 500, and 800 acid to water solution. On all the plots, turfgrass growth increment and visual quality were measured at fried times. The data were subjected to paired samples t-test and corelation analysis. The summarized results are as follows; 1) Leaf growth increment, density, and root spread depth of turfgrass treated with 1: 500 and 1: 800 diluted pyroligneous acid were significantly superior to the control. Particularly, 1: 500 diluted solution was superior to the others. 2) Color, texture, and uniformity of turfgrass treated with 1: 500 and 1: 800 diluted pyroligneous acid were significantly superior to the control. Especially, 1: 500 diluted solution tended to be superior to the others. 3) There were no symptoms of disease in all plots treated with the diluted pyroligneous acid. 1 500 and 1: 800 diluted pyroligneous acid were not thought to trigger or promote disease. 4) Before and after investigating the effect of pyroligneous acid on turfgrass growth ,the soils were analyzed. In all treatments, the chemical properties of the soils did not change noticeably. The chemical properties of the soils might be not changed by the diluted pyroligneous acid treatments. 5) Considering the results mentioned above, 1: 500 diluted pyroligneous acid was the most effective. Though pyroligneous acid is an organic fertilizer and contains only a little nitrogen and phosphorus, 1: 500 diluted pyroligneous acid promoted turfgrass growth effectively. Thus this use might lead to a reduction in the amount of fertilizers used and result in ecologically responsive management of Korean golf courses.
