The role of the integrated development environment is very important in software development of a development project. After many developers develop different modules, software product is completed through compile, debugging, integration, testing, and distribution. However, bugs and various issues in the development process cause problems such as quality deterioration of software product and dissatisfaction with requirements. So the need for automated testing to avoid these problems and improve quality has increased. In this study, we propose test automation modules of four perspectives to improve quality throughout the test automation in an integrated development environment. Each automation module operates through the tool chain of an integrated build framework implemented on the devops.

Purpose: To investigate the impact of hyperglycemia during inductive treatment on the prognosis of acute lymphocytic leukemia (ALL) in children. Materials and Methods: Clinical data of 159 ALL childhood cases were reviewed. The patients were divided into the hyperglycemia group (fasting $glucose{\geq}126mg/dl$ and/or random blood $glucose{\geq}200mg/dl$) and the euglycemia group according to the blood glucose values. The X2 test was performed to compare the complete remission rates of the two groups, and Kaplan-Meier and log-rank tests were performed to compare the 5-year overall and relapse-free survival. Results: The incidence of hyperglycemia in the $age{\geq}10-year-old$ group was higher than the younger-age group (P=0.009). Values in the interim- and high-risk groups were higher than the standard-risk group (P=0.028), while there was no significant difference between genders (P=0.056). The complete remission rates of the 2 groups demonstrated no significant difference (P=0.134), while the 5-year OS of the hyperglycemia group was lower than in the euglycemia group ($83.8{\pm}6.0%$ vs $94.9{\pm}2.4%$, P=0.014). The 5 -year RFS was significantly lower than the euglycemia group ($62.9{\pm}8.7%$) vs $80.2{\pm}9.1%$, P<0.001). Conclusions: Children with $age{\geq}10year$ old, and in the middle- and high-risk groups appear prone to complicating hyperglycemia during inductive chemotherapy, associated with lower 5-year OS and RFS.

Purpose: This study investigated effect of the scapular retraction exercise on the subacromial and costoclavicular space using different thera-band intensities. Methods: Thirty-six healthy adults participated in this study, and the subjects were randomly divided into three groups (low, moderate, and high-intensity groups). The exercise was conducted twice a week for three weeks. The subacromial and costoclavicular space were measured before and after the intervention via ultrasonography. Data analysis was performed using the two-way Analysis of Variance with repeated measures and the paired t-test. Results: The effect of the scapular retraction exercise on the subacromial and costoclavicular space using a thera-band after a 60° shoulder abduction has significant difference in all groups (p<0.05). However, there was no significant difference between the groups, and the values in the groups before the exercise did not differ significantly from those after the exercise (p>0.05). Conclusion: Our results indicate that the scapular retraction exercise after a 60° shoulder abduction can be used to widen the subacromial and costoclavicular spaces.

Embedded systems are used in many fields such as home appliances, terminals, controls, communications, etc. So, to manage, control, and test these embedded systems, monitoring programs have been developed variously. In this paper, to overcome the characteristic faults of embedded systems which have resource restrictions, we implemented a development environment based on NFS and designed a monitoring tool that can evaluate and analyze kernel performance in embedded equipment by using LTT(Linux Trace Toolkit). Also, we designed a method to show monitoring data collected by using a monitoring tool, called MONETA 2.0, through the web-page.

Increasing use of embedded systems has made many improvements on hardware development for specific purpose. Hardware changes are more expensive and harder to implement rather than software changes. Developers need tools to do design and testing of new hardware. Many simulation tools have been made to mimic the hardware and allow developer to test programs on top of new hardware. Virtual Development Environment for Embedded Software (VDEES) is one of the alternatives available. It provides an open source based platform and an Integrated Development Environment (IDE) that can be used to build and testing newly made component, faster and at low-cost.

This paper presents new practical accelerated life test plans with different censoring times at three levels of stress for Weibull and lognormal lifetime distributions, respectively. The proposed plans are compared with the corresponding two-level statistically optimal plans and three-level compromise and practical plans. Computational results indicate that new practical plans have been more precise and effective than the existing three-level plans under a constraint of total testing time. In addition, a procedure to determine useful ALT plans is illustrated with a numerical example.

This study shows method of measuring mechanical stresses during short circuit test, to evaluate numerical analysis of short circuit force. As test model, 400kVA transformers are used, to acquire short circuit force acceleration sensors used. Weak region of winding is found through short circuit test, and verification data of numerical calculation is obtained.

Launch vehicles are exposed to aerodynamic heating conditions while flying at high Mach numbers in the atmosphere. In this study aerodynamic heating test for fairing nose-cone was done using ATSF(Aerodynamic Thermal Simulation Facility) and Engineering Model for fairing. ATSF is a facility that can simulate given temperature profile using about 4,000 halogen heaters on fairing model. Aerodynamic heating profile is got from result of thermal analysis using MINIVER, Thermal Desktop and SINDA/FLUINT. After aerodynamic heat test, it is found that initial temperature of fairing inner surface and thickness of BMS has important effects on temperature of fairing inner surface. Also it is confirmed that maximum temperature of fairing nose-cone inner surface during flight is lower than allowable temperature limit. Later, thermal correlation between thermal analysis and experimental results will be done using aerodynamic heating test result

Deployable structure is a system on which the study is being actively performed in various fields including architecture field. However, There is little study which can enhance the practicality since the interpretation condition is difficult as the unstable structure in the architecture field. In this study, the Scissors system has been focused on among the Deployable structure. The structure was developed using the Scissors system and the Mock-up test was performed. Through this, the unfolding method was proposed and the practicability was surveyed through the specific design of the Test model. Also, the structure stability was reviewed through structure analysis of Mock-up test model. and stabilizing method was proposed.

We consider the problem of testing cell probabilities in sparse multinomial data. Aerts, et al.(2000) presented $T_1=\sum\limits_{i=1}^k(\hat{p}_i-p_i)^2$ as a test statistic with the local polynomial estimator $(\hat{p}_i$, and showed its asymptotic distribution. When there are cell probabilities with relatively much different sizes, the same contribution of the difference between the estimator and the hypothetical probability at each cell in their test statistic would not be proper to measure the total goodness-of-fit. We consider a Pearson type of goodness-of-fit test statistic, $T=\sum\limits_{i=1}^k(\hat{p}_i-p_i)^2/p_i$ instead, and show it follows an asymptotic normal distribution.
