Purpose: The purpose of this study was to identify pain intensity according to activities over postoperative days and to identify factors of patient satisfaction with pain management after abdominal surgery. Methods: The subjects were 123 patients who were admitted at a general surgical ward and had abdominal surgery from Mar. 2005 to June 2005. The collected data were analyzed using the SPSS 12.0 program. Results: The average postoperative pain scores were 6.13 at POD 1, 5.46 at POD 2, and 4.22 at POD 3. In stepwise multiple regression analysis a total of 40% of variance in satisfaction with pain management was accounted for by pain intensity on POD 3 at rest (29.4%) and attitude toward using pain medicine (6.6%), and side effects of pain medicine (4.0%). Conclusion: According to the findings of this study, patients had inadequate pain management after abdominal surgery. Therefore, nurses need to provide educational programs focused on changing attitudes toward using pain medicine, to reduce side effects of pain medicine, and to develop nursing intervention for relieving pain.

This study does a qualitative and quantitative analysis of how music by humming is being used by music educators in the classroom. Music by humming is part division of music information retrieval. In order to define what a music information retrieval system is first I need to define what it is. Berger and Lafferty (1999) define information retrieval as "someone doing a query to a retrieval system, a user begins with an information need. This need is an ideal document- perfect fit for the user, but almost certainly not present in the retrieval system's collection of documents. From this ideal document, the user selects a group of identifying terms. In the context of traditional IR, one could view this group of terms as akin to expanded query." Music Information Retrieval has its background in information systems, data mining, intelligent systems, library science, music history and music theory. Three rounds of surveys using question pro where completed. The study found that there were variances in knowledge, training and level of awareness of query by humming, music information retrieval systems. Those variance relationships where based on music specialty, level that they teach, and age of the respondents.

Background: The purpose of this study was to investigate the associations among the internal health locus of control, depression, perceived health status, self efficacy, social support, and health-promoting behavior in Iranian breast cancer survivors and to determine influential variables. Materials and Methods: A predictive design was adopted. By convenient sampling the data of 262 breast cancer survivors in Iran were collected by questionnaires during 2014. Data were analyzed applying descriptive statistics, t-tests, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. Results: The internal health locus of control, depression, perceived health status, self efficacy, social support and undergoing chemotherapy all correlated significantly with the health-promoting lifestyle. Stepwise multiple regression analysis revealed that social internal health locus of control, depression, perceived health status, self efficacy and social support and chemotherapy accounted for about 39.8% of the variance in health promoting lifestyle. The strongest influence was social support, followed by self efficacy, perceived health status, chemotherapy and depression. Conclusions: The results of the study clarifed the seriousness of social support, self efficacy, perceived health status and depression in determining the health-promoting lifestyle among Iranian breast cancer survivors. Health professionals should concentrate on these variables in designing plans to promoting a healthy lifestyle.

Purpose: This study was done to investigate the effect of self-esteem on perceived stigma in high school students toward people with disabilities. Methods: The participants in this study were 140 high school students from Gyeonggi Province. Data were collected during May 2013. Structured questionnaires were used for data collection. Data were analyzed using descriptive by statistics, t-test, ANOVA, Pearson correlation coefficients, and simple regression analysis with the SPSS 19.0 program. Results: The major findings of this study are as follows: There was a significant relationship between stigma toward people with disabilities and self-esteem among the high school students (r=-.205, p=.015). There was also a significant relationship between relationships with friends (r=.291, p<.001), health statement (r=.400, p<.001) and self-esteem among the high school students. Self-esteem explained 3.5% of the variance in high school students' stigma toward people with disabilities (F=6.041, p=.015). Conclusion: Findings of this study suggest a need to develop education to increase self-esteem as a strategy to decrease high school students' stigma toward people with disabilities. Also, findings of this study suggest the need for repeated study on the relationship between self-esteem and stigma toward people with disabilities among adults.

Ultrasonic travel-times obtained with the LCR ultrasonic technique have shown an ability to distinguish among three aluminum plates. The 244$\times$150mm thick, but differ in heat treatment. One is fully annealed, the second is quenched and then tempered, and the third is heat-treated to T651 plate, as received plate. Travel-times were obtained at four locations on each side of all plates. The data for both sides of each plate clearly are in very close agreement except location 1 of each plate. In order to show travel-time variation throughout the plate areas, the average travel-time for both sides of each plate were calculated. For Plate 1, the travel-time data were the highest and the data of Plate, the travel-time data were the highest and the data of Plate 2 were upper than Plate 3. Finally, the residual stresses for each plate were measured by X-ray diffraction method. The results showed a good relation. These preliminary results indicate that the LCR Ultrasonic Technique may be not only further developed for use in quality control in the manufacture of rolled aluminum plates but also industry.

Purpose: This study aimed to provide the baseline data for improving self-esteem under the influences of parental and peer attachment and depression in adolescents. Methods: The data were collected from 200 middle and high school students in D metropolitan city by completing questionnaires from August 19 to August 30, 2013. Results: The results of this study were as follows: The self-esteem was significantly different in academic grades, father's education level and economic status in adolescents. The relation of the variables to self-esteem by the statistical power in order was depression, peer attachment and parental attachment. The more the subjects were depressed, the more self-esteem dropped. The better parental and peer attachment, and household socio-economic status, the higher self-esteem was. Stepwise multiple regression analysis showed the level of parental and peer attachment and depression, which explained 38% of the total variance in self-esteem. Conclusion: Adolescents who had high self-esteem could reduce their depression and form good parental and peer attachment that would prevent them from being maladjusted. These results will affect the various activities of adolescent. Therefore, the way in which adolescents can improve their self-esteem should be found.

Filtering genes that do not appear to contribute to regulation prior to the statistical analysis of time course gene expression data can reduce the dimensions of data and the possibility of misinterpretation due to noise or lack of variation. In this paper, we compare six different functions for filtering genes with flat pattern under the percentile criterion on an observed sample and that on a bootstrap sample. The result of applying to the yeast cell cycle data shows that the variance function is most similar in both samples.

A multi-objective design exploration for a three-element airfoil consisted of a slat, a main wing, and a flap was carried out. The lift curve improvement is important to design high-lift system, thus design has to be performed with considered multi-angle. The objective functions considered here are to maximize the lift coefficient at landing and near stall conditions simultaneously. Kriging surrogate model which was constructed based on several sample designs is introduced. The solution space was explored based on the maximization of Expected Improvement (EI) value corresponding to objective functions on the Krigingmodels. The improvement of the model and the exploration of the optimum can be advanced at the same time by maximizing EI value. In this study, a total of 90 sample points are evaluated using the Reynolds averaged Navier-Stokes simulation(RANS) for the construction of the Kriging model. In order to obtain the information of the design space, two data mining techniques are applied to design result. One is functional Analysis of Variance(ANOVA) which can show quantitative information and the other is Self-Organizing Map(SOM) which can show qualitative information.
