  • This study aims to extensively analyze the performance of various Machine Learning (ML) techniques for predicting version to version change-proneness of source code Java files. 17 object-oriented metrics have been utilized in this work for predicting change-prone files using 31 ML techniques and the framework proposed has been implemented on various consecutive releases of two Java-based software projects available as plug-ins. 10-fold and inter-release validation methods have been employed to validate the models and statistical tests provide supplementary information regarding the reliability and significance of the results. The results of experiments conducted in this article indicate that the ML techniques perform differently under the different validation settings. The results also confirm the proficiency of the selected ML techniques in lieu of developing change-proneness prediction models which could aid the software engineers in the initial stages of software development for classifying change-prone Java files of a software, in turn aiding in the trend estimation of change-proneness over future versions.

  • This study aims to monitor the variation of modal frequencies of steel buildings during their construction sequence. In this respect, construction of a steel building is followed by vibration based measurements. The monitored building is a three-story educational building within a building group whose structural system consists of steel moment resisting steel frames and eccentric braces. Five different acceleration measurements in two perpendicular directions are taken on five different construction stages, starting from the erection of the columns and beams ending with the completion of the construction. The recorded measurements are transferred into frequency domain and the dominant frequencies for each case have been determined. The change in the dominant frequencies is evaluated with the existing construction stages and performed constructional works between the stages. The last measurement, performed on the building in service, revealed the first two dominant frequencies as mutual in X and Y direction, showing that these dynamic modes are torsional modes. This result is investigated by numerical analysis performed with finite element model of the building constructed for design purpose. Lower frequencies and different mode shapes are determined from numerical analysis. The reason of lower frequencies is discussed and the vibration survey is extended to determine the effects of an adjacent building. The results showed that the building is in strong relation with an adjoining building in spite of a designed construction joint.

  • This study was conducted to investigate effect of low temperature and ripeness stages on fruit quality of chilli pepper (cv. Nockgwang) during storage at 5, 7, and $10^{\circ}C$. Fruits at three ripeness stages were selected based on uniform fruit size and three maturities on peel color: S1 (fully developed fruit just before the onset of ripening), S2 (fruits in the onset of color change), and S3 (fruits in completely red in color). Lower temperature attributed to increase fruit weight loss (WL) and WL was higher in S2 than the other ripeness stages. The highest respiration rate and ethylene production was found at S2 fruit while those of fruit in green and red showed similar and remained lower level during storage. Electrolyte leakage (EL) was higher as storage temperature decreased. After 28 d storage, EL rates of fruits at $5^{\circ}C$ were 43, 36, and 17% in S1, S2, and S3 while those at $10^{\circ}C$ were 17, 19, and 14%, respectively. These results show that chilli pepper fruits are tended to lose more water at lower temperature partially associated with increased EL. Thus, threshold storage temperature must be considered for avoiding chilling during storage and for extending the storage life of fresh pepper fruits.

  • This study based on the 8-step strategy model for change management proposed by J. P. Kotter, tried to check the perception and experience about change management of the librarians at National Library of Korea. Also this study aimed to figure out the understanding of each 8-step strategy model. To this end, the concept and process of change management were presented through literature analysis, and survey was conducted targeting 58 librarians of the National Library of Korea. This study drews five results. First, the majority of librarians at National Library of Korea do not know about change management, and they do not have experience in using change management techniques. Second, the period required for the 8-step change management process is 5 years. Third, during the change management stage, librarians' awareness of the importance of stages 4 and 3 was high. Fourth, there is no difference in the librarians' perceptions of change management by gender, education, major, and tasks. Fifth, there is a significant difference in the age and service years of the librarian in the 3rd, 4th, and 7th stages of change management. Also there is a significant difference in the position of the librarian at the 1st and 3rd stage of change management, and between librarians' department and 1st stage of change management. The findings and results of this study can not only raise awareness of change management but also suggest organizational responses to change at individual or organizational level.

  • This study was designed to investigate the relationship between the stages of exercise behavior change and physical self-concept and self-efficacy of security employees in hotel casinos. The sampling was drawn from employees at 8 casinos which had more than 30 employees. Participants were selected by convenience sampling method and they completed questionnaires about Physical Self-Concept and Self- Efficacy by self-administration method under supervision of trained researchers SPSS 16.0 (Statistical Package for the Social Science) was used for data analysis in the present study. Reliability and validity were examined for the present study. The principle component factor analysis and varimax rotation were used for the present study. Eigen value 1.0 was the criterion for selecting factors. Chi-square (X) 2 test was utilized for measuring the difference in gender and types of job duties at the stages of exercise behavior change. One-way ANOVA was employed to examine the relationship between the stages of exercise behavior change as an independent variable and physical self-concept and self-efficacy as dependent variables. The Scheffe method was used to determine mean differences of groups as a follow-up test. Multiple regression analysis was utilized to test the difference of physical self-concept as dependent variable and self-efficacy as independent variable. To verify hypothesis for the study, a statistical significance level of $\alpha$=.05 was used. The results were as follow: first, there were differences found for gender and types of job responsibilities in the stages of exercise behavior change. Secondly, as security employees progressed through the stages of exercise behavior change, their physical self-concept and self-efficacy improved. Finally, physical activity and body fat had significant main effects on self-efficacy.

  • The study objectives were to increase both the stage of readiness to eat fruit and vegetables as well as the intakes of women who participated in the Expanded Food and Nutrition Education Program (EFNEP) for families with limited incomes. The intervention was to enhance the currently used curriculum, Eating Right Is Basic III (ERIB3), with stage-specific processes based on the Trans-Theoretical Model of readiness to change. Trained EFNEP community workers taught the enhanced curriculum to 90 mothers in the experimental county and to 53 mothers in the control county. Pre- and post-intervention measures included stages of readiness to eat fruit and vegetables and to intake as assessed by 24-hour dietary recalls and staging questions. Most women recruited into EFNEP were in Action and Preparation Stages (53.5%). Fruit and vegetable intakes showed a linear trend along with the Stage of Change for fruit and vegetable. After intervention, some combination of the ERIB3 and the fruit and vegetables-enhanced ERIB3 resulted in a reported 1/2 servings/day increase in fruits and vegetables in both the control and the experimental counties, although changes were not significant. EFNEP women also moved along the Stage of Change Continuum for fruits and vegetables in both counties. The percentage of people who ate 5 or more servings of fruit and vegetables was significant, however, only in the experimental group. We encourage health professionals to apply lessons learned from this intervention and to continue to pursue theoretically based interventions to change dietary behaviors.

  • This study divided school age by considering a change in the stage of body growth by age in elementary schoolgirls with the use of body scan data, and considered by comparing body size characteristics by school age. Elementary schoolgirls' body shape cannot be divided clearly. However, ages 7-10 were bound into the same group for the majority of girth, width, and thickness items. 7-8 years old, 9-10 years old, and 11-12 years old were bound into the same group in most items except ages 9 and 10 for the height item. Thus, significant difference was indicated between groups. Accordingly, this study divided the school age into three periods such as early stage(ages 7-8), middle stage(ages 9-10), and late stage(ages 11-12) in consideration of the stages for elementary schoolgirls' body-shape growth. As a result of analyzing body size according to division of school age, the higher school age leads to continuous growth. The notable growth was indicated especially in the middle stage and late stage. Examining centering on typical items related to the clothing construction, there was notable increase in waist thickness and hip thickness between early and middle stages and in height, weight, breast girth, waist circumference, back length, breast width, and waist width between middle and late stages. On the other hand, hip circumference, hip width, breast thickness, and length between shoulder edges were indicated to grow relatively and evenly among early, middle, and late stages. The lateral form was shown a clear difference in the forms of early, middle, and late stages in height and length of the whole body shape and in side thickness. The early and middle stages belong to body shape that abdomen is projected to be curved. The late stage showed right body shape which is straight and stable form in posture.

  • This paper is to study on the change of volume and temperature of the solution which mixed water with ethanol. And its main purpose is to examine closely how the volume changes, and to find the method to maximize the change of the volume. The summaries for results of the study are; First, we were known that water and ethanol are homogeneously mixed. But two solvents does not mix homogeneously by different specific gravity at early stages. Second, we could see that the volume changed large at homogeneous mixed water with ethanol by stirrer, the change of volume is the largest value when water mixed with ethanol in the ratio of one to one. Third, when water mixed with ethanol in the ratio of one to one, the change of temperature is very large by activated hydrogen bond. We conclude that it is the best result when ratio of water and ethanol is one to one and the solution is well mixed.
