Software today has become an inseparable part of our life. In order to achieve the ever demanding needs of customers, it has to rapidly evolve and include a number of changes. In this paper, our aim is to study the relationship of object oriented metrics with change proneness attribute of a class. Prediction models based on this study can help us in identifying change prone classes of a software. We can then focus our efforts on these change prone classes during testing to yield a better quality software. Previously, researchers have used statistical methods for predicting change prone classes. But machine learning methods are rarely used for identification of change prone classes. In our study, we evaluate and compare the performances of ten machine learning methods with the statistical method. This evaluation is based on two open source software systems developed in Java language. We also validated the developed prediction models using other software data set in the same domain (3D modelling). The performance of the predicted models was evaluated using receiver operating characteristic analysis. The results indicate that the machine learning methods are at par with the statistical method for prediction of change prone classes. Another analysis showed that the models constructed for a software can also be used to predict change prone nature of classes of another software in the same domain. This study would help developers in performing effective regression testing at low cost and effort. It will also help the developers to design an effective model that results in less change prone classes, hence better maintenance.

In this paper, the relationship of chamber contamination and the intensity change of specific wavelength was investigated. "diff_CO" formula was introduced to rule out background noise caused by external conditions and to detect when the polymer is removed from the chamber. As RF time increased, diff_CO trend showed the decrease of the maximum peak and increased number of small intensity peaks. From the diff_CO change, it was possible to determine when the chamber needs to be cleaned without opening the chamber.

Neospora caninum is an important cause of abortion in cattle, and dogs are its only known definitive host. Its seroprevalence among domestic urban and rural dogs and feral raccoon dogs (Nyctereutes procyonoides koreensis) in Korea was studied by indirect fluorescent antibody test (IFAT) and by the neospora agglutination test (NAT), respectively. Antibodies to N. caninum were found in 8.3% of urban dogs and in 21.6% of dogs at dairy farms. Antibody titers ranged from 1:50 to 1:400. Antibodies to N. caninum were found in six (23%) of 26 raccoon dogs. However, the potential role of raccoon dogs as a source of horizontal transmission of bovine neosporosis needs further investigation. The results of this study suggest that there is a close relationship between N. caninum infection among dairy farm dogs and cattle in Korea. This study reports for the first time upon the seroprevalence of N. caninum infection in raccoon dogs in Korea.

This study was done to suggest basic modifications in the present situation for the family of women in labour which is a separation management method. The study design was a descriptive study. The number of the subjects were 80. they were husbands, mothers in law, and mothers of women in labour who were full term and for whom there were no complications, either for the mother or the fetus. Data collection was done with a structured questionnaire which was analyzed using frequencies. The results were as follows, 1. Most of the subjects(95.0%) wanted to participate in the labour process. 2. The subjects wanted to support the women in labour by way of encouraging(95.0%), consoling (95.0%), listening to(75.0%), praying with(68.8%), hand holding(97.5%), stroking(63.8%), helping with respiration control(50.0%), maintaining relaxation(46.3%), changing position(58.8%), and illustration (58.8 %). 3. The subjects answered that they expected their participation to have the effect of an easier labour course(52.5%), security for the women in labour(95.0%), and providing a better relationship between the women in labour(66.3%) and the new baby(55.0%). 4. The priority of the response as to who is the best supporter was husband, and mother of the women in labour in that order. It can be concluded that nurses maintained a management method which ignored the needs of the families of women in labour. If given consideration is to be given to these subjects, future programs should initiate ways to let the families participate in the labour process.

Purpose: The purpose of this study was to explore the relationships among workplace bullying, organizational commitment, and turnover intention of nurses. Methods: A cross-sectional study was conducted. Data were collected using a structured questionnaire from nurses at five public hospitals (N=190). Results: The experience of bullying was 31.29 points (range 16-64) on average: Work-related bullying was the highest, followed by verbal/non verbal bullying and external threats. The consequences of bullying were 30.54 points (range 13-52) on average: The physical/psychological withdrawal was the highest, followed by increasing distrust and the poor quality of patient care. The experiences of bullying had positive correlations with the consequences of bullying (r=.55, p<.001) and the turnover intention (r=.27, p<.001), and had a negative correlation with organizational commitment (r=-.28, p<.001). The consequences of bullying had a positive correlation with the turnover intention (r=.52, p<.001), and had a negative correlation with organizational commitment (r=-.49, p<.001). Organizational commitment showed a negative correlation with the turnover intention (r=.63, p<.001). Conclusion: The findings of this study suggests the needs of a regular monitoring system and organizational management for workplace bullying, which helps nurses to commit to their organization and to be retained in a workplace.

A marine SCR System is emerging as an alternative to comply with NOx Tier III Emission standards, a restriction on greenhouse gas from vessels implemented by the International Maritime Organization. The system is greatly affected by the uniformity of the fluid flowing into the catalyst, so the performance of the catalyst of an SCR system needs to be guaranteed. This study conducted research on a mixed evaporator of an SCR system, which is one of the factors affecting the uniformity of the fluid. When the angle of the mixed evaporator is set to $90^{\circ}$, the fluid uniformity is at its highest at 83%, under the condition that the length of the mixed evaporator be 3.5 D. When the length was 3.5 D and less, the fluid uniformity had a tendency to improve relative to the case without a bent pipe. However, a longer mixed evaporator results in a more perfect liquidity development in the pipe with a liquidity distribution similar to the case where no curved pipe is formed in front of the catalyst. A lower angle for the mixed evaporator results in a lower flow uniformity, and a longer length of the mixed evaporator results in a lower difference in the flow uniformity caused by the angle. The flow uniformity can be improved by 6% with a mixed evaporator, which confirmed that all factors applied to an SCR system have a close relationship with the efficiency.

The live fire test has been playing a critical role in evaluating the goals-to-meet of the weapon systems which utilize the power of explosives. As such, the successful development of the test systems therein is quite important. The test systems development covers that of ranges and facilities including system-level key components such as mission control, instrumentation or observation, safety control, electric power, launch pad, and so on. In addition, proper operational guidelines are needed with well-trained test and operation personnel. The emerging weapon systems to be deployed in future battle field would thus have to be more precise and dynamic, smarter, thereby requiring more elaboration. Furthermore, the safety consideration is becoming more serious due to the ever-increasing power of explosives. In such a situation, development of live fire test systems seems to be challenging. The objective of the paper is on how to incorporate the safety and other requirements in the development. To achieve the goal, an architectural approach is adopted by utilizing both the system components relationship and safety requirement when advanced instrumentation technology needs to be developed and deteriorated components of the range are replaced. As an evaluation method, it is studied how the level of maturity of the test systems development can be assessed particularly with the safety requirement considered. Based on the concepts of both systems engineering and SoS (System-of-Systems) engineering process, an enhanced model for the system readiness level is proposed by incorporating safety. The maturity model proposed would be helpful in assessing the maturity of safety-critical systems development whereas the costing model would provide a guide on how the reasonable test resource allocation plan can be made, which is based on the live fire test scenario of future complex weapon systems such as SoS.
