As part of efforts to internally strengthen the research ethics capacity of the Korean Academy of Health Policy and Management, we have compiled research ethics issues that are frequently encountered in public health researches. Firstly, when reusing research reports or dissertations as papers, efforts should be made to avoid unfair duplicate publication. Compliance with the institutional review board exemption process is required, and additional efforts should be devoted during the text recycling process to prevent self-plagiarism or unjust duplicate publication.

This study aimed to investigate beginner-level learners' use of translators in L2 writing, and shed light on its validity in writing performance through their responses on the necessity, reliability and limitation of machine translation. 117 university students from beginner-level L2 writing classes participated in the survey. Additionally, 11 of them were interviewed about their answers. The survey and interview data revealed varying viewpoints such as reliability and effects as well as reasons for choosing translator-assisted writing. The vast majority(76.1%) used web-based machine translators for their writing activities, and employed various strategies to help their insufficient L2 skills and to increase their motivation and confidence. On the other hand, they exhibited its detrimental effects including it could lead to plagiarism, and interfere with the learning process unless they post-edited the given translation. However, translators were viewed as a new, efficient, and valid educational tool for effective and successful L2 writing.

Competition in the modern CPU market has shifted from speeding up the clock speed of a single core to increasing the number of cores. As such, there is a growing interest in parallel programming to maximize the use of resources of many core processors. In this paper, we propose parallel programming models in Haskell to find an advisable parallel programming model for many-core environments. Specifically, we used Eval monad and Cloud Haskell to develop two versions of parallel programs: plagiarism detection and K-means. Then, we evaluated the performance of the developed programs in 32-core and 120-core environments. The results of our experiment show that the Eval monad is highly efficient in an environment with a small number of cores. On the other hand, the Cloud Haskell runtime shows 37% improvement over Eval monad and the scalability shows a 134% improvement over Eval monad as the number of cores increases.

Although the performance of computer hardware is increasing due to the development of manycore technologies, software lacking a proportional increase in throughput. Functional languages can be a viable alternative to improve the performance of parallel programs since such languages have an inherent parallelism in evaluating pure expressions without side-effects. Specifically, Haskell is notably popular for parallel programming because it provides easy-to-use parallel constructs based on monads. However, the scalability of parallel programs in Haskell tends to fluctuate as the number of cores increases, and the garbage collector is suspected to be the source of this fluctuations because it affects both the space and the time needed to execute the programs. This paper uses the tuning tool, GC-Tune, to improve the scalability of the performance. Our experiment was conducted with a parallel plagiarism detection program, and the scalability improved. Specifically, the fluctuation range of the speedup was narrowed down by 39% compared to the original execution of the program without any tuning.

Since the paper plagiarism has become one of important social issues, it is necessary to develop system for measuring the similarity between papers. The speed and accuracy of the system are very important features. So many researchers are studying the features. In this paper, we propose a preprocessing method using 'Global Dictionary' model to enhance performance of the system. The global dictionary includes information of all words in the document repository. The system uses the model to find similar papers with low computing time. Finally our experiment showed that a set of more than 20,000 documents could be reduced to about 50 documents drastically by our filtering techniques, which proves the excellence of our system.

We investigated gifted students' scientific integrity, perception of scientific misconduct and needs for research ethics education. For this study, 267 science academy students who have participated in R&E program responded to questionnaire of those three parts. The major findings are as follows: First, 45.31% of gifted students answered that they had one or more experiences in five categories; fabrication, falsification, plagiarism, unfair authorship, and connivance of scientific misconduct. Second, almost 90% of gifted students responded that statements of questions are scientific misconduct except the self plagiarism. Third, 28.83% of gifted students needed to study research ethics and all of them were 1st graders. Fourth, they wanted to know specifically the limit of apt citation, writing skills of research notes, specific examples of scientific misconduct, and concrete acting method for scientific integrity, etc. In order to get gifted students to conduct their research responsibly, educators have to consider and reflect the voice of gifted students.

In this paper, we propose the similarity measurement method between two program codes by counting the frequency and length of continuous patterns of specifiers and keywords, which exist in two program codes. In addition, we propose the visualization method of this analysis result by formal concept analysis. Proposed method considers adjacencies of specifiers or keywords, which have not been considered in the previous similarity measurements. Proposed method can detect the plagiarism by analyzing the pattern in each function regardless of the order of function call and execution. In addition, the result of the similarity measurement is visualized by the lattice of formal concept analysis to increase the user understanding about the relations between program codes. Experimental results showed that proposed method succeeded in 96% plagiarism detections. Our method could be applied into the analysis of general documents.

The present study was conducted to investigate science and engineering graduate students' proficiency in technical English writing and their perceptions of research ethics. Given that graduate students in science and engineering colleges usually write journal articles as well as dissertations in English, this study examined their experience of and preparation for technical English writing, writing practices, and research ethics including plagiarism. The results of the study show that it is very necessary to intensify education on research ethics and to provide educational training in proper citation practices. These findings can be used as a basis for the development of future academic curricula and other support resources to improve science and engineering graduate students' technical English writing.
