An off-line programming, OLP, system is widely used in automation fines. To help an on-line robot system to carry out desirable tasks planned by the off-line simulation, an approach to the real-time communication is presented. The OLP system developed consists of a software, a host computer(PC), a SCARA robot body, four servo drivers, and four independent joint controllers. This study focuses on the software where real-time communication is included. The software, can be used in teaching, trajectory planning, real-time running, and performance evaluation. The evaluation of different control algorithms is one of the merits of the software. The software can give servo commands for task running. A comparison of generated and corresponding actual trajectories provides the evaluation of task performance. The safety, of the OLP system is ensured by alarming malfuntions of the system. The OLP system developed can reduce the teaching time and increase the user's convenience.

Release planning in a software product line (SPL) is to select and assign the features of the multiple software products in the SPL in sequence of releases along a specified planning horizon satisfying the numerous constraints regarding technical precedence, conflicting priorities for features, and available resources. A greedy genetic algorithm is designed to solve the problems of release planning in SPL which is formulated as a precedence-constrained multiple 0-1 knapsack problem. To be guaranteed to obtain feasible solutions after the crossover and mutation operation, a greedy-like heuristic is developed as a repair operator and reflected into the genetic algorithm. The performance of the proposed solution methodology in this research is tested using a fractional factorial experimental design as well as compared with the performance of a genetic algorithm developed for the software release planning. The comparison shows that the solution approach proposed in this research yields better result than the genetic algorithm.

In this paper, we proposed comparison of software education units according to 2015 Revised National Curriculum. Comparative analysis of 6 Practical Arts textbooks was conducted especially on the software education units. The analysis criteria were decided to be unit system, unit structure, learning objectives, the way of placing contents, activities, supporting materials, providing resources, and evaluation. As a result, the software education units have secured a lot of quantity compared to the total number of units. And the affective domain of the learning objectives is shown to be lacking. All the textbooks were uniformly arranged the component of contents described in 2015 revised national curriculum. Cooperative activities are strengthened compared to the previouse curriculum. On the other hand, evaluations have a large variation among textbooks and some have fewer types.

Bug report processing is a key element of bug fixing in modern software maintenance. Bug reports are not processed immediately after submission and involve several processes such as bug report deduplication and bug report triage before bug fixing is initiated; however, this method of bug fixing is very inefficient because all these processes are performed manually. Software engineers have persistently highlighted the need to automate these processes, and as a result, many automation techniques have been proposed for bug report processing; however, the accuracy of the existing methods is not satisfactory. Therefore, this study focuses on surveying to improve the accuracy of existing techniques for bug report processing. Reviews of each method proposed in this study consist of a description, used techniques, experiments, and comparison results. The results of this study indicate that research in the field of bug deduplication still lacks and therefore requires numerous studies that integrate clustering and natural language processing. This study further indicates that although all studies in the field of triage are based on machine learning, results of studies on deep learning are still insufficient.

In software development, the quality of a product often depends on whether its developers can rapidly find and contribute to the proper tasks. Currently, the word data of projects to which newcomers have previously contributed are mainly utilized to find appropriate source files in an ongoing project. However, because of the vocabulary gap between software projects, the accuracy of source file identification based on information retrieval is not guaranteed. In this paper, we propose a novel source file identification method to reduce the vocabulary gap between software projects. The proposed method employs DBPedia Spotlight to identify proper source files based on semantic similarity between source files of software projects. In an experiment based on the Spring Framework project, we evaluate the accuracy of the proposed method in the identification of contributable source files. The experimental results show that the proposed approach can achieve better accuracy than the existing method based on comparison of word vocabularies.

We survey the software faults according to the software characteristics, so we can use it to make a software testcases. We divide the software fault according to six characteristics, functionality, usability, reliability, efficiency, maintainability, and portability. We analyze the software faults to find the common factors according to the software products, also we survey the number of faults according to six characteristics. We propose the method of weight application using the relative comparison of the number of faults.

This study investigates factors that impact dating relationship stability(DRS) among college students by applying two key concepts from the Interdependence Theory suggested by Kelly & Thibaut (1978; Thibaut & Kelly, 1959), the comparison level(CL) and comparison level for alternatives($CL_{alt}$). This study also examined mediating effects of commitment on the relationship between CL and DRS and $CL_{alt}$ and DRS. The research used a survey data set drawn from 327 college students currently involved in a dating relationship. The collected data set was then analyzed using SPSS software ver. 23.0 and AMOS software ver. 25.0, to produce the descriptive statistics, Pearson's correlations, and path analysis with bootstrapping. First, both CL and $CL_{alt}$ had a significant direct impact on DRS. In terms of effect size, CL's effect size was comparatively larger than $CL{_{alt}}'s$. The mediating effects from the commitment were evidenced. In the model, the commitment partially mediated the relationships between CL and DRS, and $CL_{alt}$ and DRS. The findings suggest that commitment still plays a key role in dating relationships among college students who currently have a romantic partner. The findings of this study show the possibilities in applying the concepts and theory of interdependence to explain current dating relationships among young adults.

There is a problem that unknown paintings are sophisticated in the level of forgery, making it difficult for even experts to determine whether they are genuine or counterfeit. These problems can be suspected of forgery even if the genuine product is submitted, which can lead to a decline in the value of the work and the artist. To address these issues, in this paper, we propose a system to classify chromaticity data among extracted data through objective analysis into quadrants, extracting comparisons and intersections, and estimating authors of unknown paintings using XRF and hyperspectral spectrum data from corresponding points.

Three categories such as the design of a machine, control and software are necessary in the development of the photomask inspection machine with high resolution. Among them, the design of a software detects inferiority through the comparison of CAD data and real data read by camera from photomask. The block matching algorithm is used since the domain is large and the comparison of data by pixel is accomplished. To correct the error arising from the assembly of a machine, calibration algorithm is used and prefocusing algorithm is suggested to correct the surface of the photomask.
