The TOEIC has widely used to evaluate business English proficiency in Korea, but those who achieved high scores still often face difficulties in performing their duties in English at work. This implies that the test may not evaluate business English proficiency effectively enough. With an ultimate goal of proposing an effective way of assessing business English proficiency, therefore, his study analyzed the predictive validity of the TOEIC. A correlation analysis was conducted between TOEIC scores of 64 office workers of multinational companies and their working skills in English evaluated by themselves, and their colleagues and seniors. Its results illustrated a significant correlation between their listening and reading scores and their working skills measured by all the groups, but not between their scores and their working skills in speaking and writing. In addition, the study did a delphi study to identify working skills in English to be assessed in business English tests and a contents analysis of the TOEIC. The results suggest business English tests should be able to assess working skills by work types and more direct testing of working skills in speaking and writing is needed.

Statistics concerning software errors indicate that more errors are introduced in analysis and design phase than implementation phase. Therefore, it is needed to check whether the design modeling is appropriate for own function and structure. This paper discussed the effective test method for the object-oriented design model, i.e., UML. A new method was proposed for generating test data. This method consists of category partition theory by the representation each element in UML model with OCL (Object Constraint Language). Test data generated in this way can be used for testing the source code functionality as well as for checking the design model.

The advent of Internet of Things (IoT) makes common nowadays computing environments involving programming not a single computer but several heterogeneous distributed computers together. Developing programs separately, one for each computer, increases programmer burden and testing all the programs become more complex. To address the challenge, this paper proposes an RPC-based unified programming language, UniPy, for development of MGC (eMbedded, Gateway, and Cloud) applications in IoT systems configured with popular computers such as Arduino, Raspberry Pi, and Web-based DB server. UniPy offers programmers a view of classes as locations and a very simple form of remote procedure call mechanism. Our UniPy compiler automatically splits a UniPy program into small pieces of the program at different locations supporting the necessary RPC mechanism. An advantage of UniPy programs is to permit programmers to write local codes the same as for a single computer requiring no extra knowledge due to having unified programming models, which is very different from the existing research works such as Fabryq and Ravel. Also, the structure of UniPy programs allows programmers to test them by directly executing them before splitting, which is a feature that has never been emphasized yet.

The purpose of this study is to understand in detail the development of infants in the 18-24-month period when language develops the most, and to prepare new standards for developmental evaluation that can promote appropriate intervention design at an early time. We divided sub-items such as screening tests and standardized test tools to know the language development ability indicators of infants aged 18-24 months were divided into syntax/phonology, meaning, and speech, and each question was classified and a checklist was made on a five-point scale to conduct a survey on parents with infants aged 18-24 months. Low sensitivity to screening of infants with language delays in nationally implemented infant health checkups, and domestic test tools are standardized for at least six to as many as 10 years, which is always possible in questionnaires related to acceptance and expression, with many reports from parents or teachers.The proportion of "wow" and "started to do" was more than 50-60%. Based on the results of this study, it is hoped that new standards for developmental evaluation will be developed to promote the design of appropriate interventions in detail at a short time.

The article highlights the educational potential of information and communication technologies in the study of philological disciplines in higher education institutions. The study aims to analyze the didactic potential of ICT in the study of philological disciplines, as well as to check the scientific hypothesis that the use of ICT in HEIs in the study of philological disciplines will intensify and enhance the effectiveness of the learning process. To confirm the validity of the hypothesis, experimental testing was carried out and the results are illustrated in the article. The above-mentioned goal of the study determined the use of theoretical and empirical methods: analysis, synthesis, generalization, and systematization of pedagogical and scientific-methodological literature to clarify the state of research problem development and to identify pedagogical foundations on which the process of ICT use is based, comparison and prediction; questioning and testing of educational process participants to understand the effectiveness of ICT use in their training in HEIs. The research results showed positive changes in all analyzed criteria in the experimental group, which is due to the introduction of additional ICT tools into the educational process of the mentioned group. The scientific novelty of the study consists in highlighting the main characteristics and didactic functions of ICT in the learning process of philological students; in covering the classification of ICT, ICT tools, and typology of training sessions using ICT in the study of philological disciplines. In the conclusion it is summarized that the introduction of modern ICT in the educational process allows intensifying the learning process, implementation of a variety of ideas, increases the pace of classes and material assimilation, influencing the motivation for learning, increases the amount of independent work of students.

Concurrent programs, which are composed of threads that can operate concurrently, are intrinsically nondeterministic. Therefore, we can not directly apply classical testing or debugging techniques developed for sequential programs to concurrent programs because of the nonreproducibility due to nondeterminism. In this paper, we present a source tranformation method to guarantee the reproducibility of multi-threaded programs written in Java programming language. Once a mutli-threaded program has been transformed according to the transformation rules, we can force the program's execution to follow the given sequence of synchronized methods repeatedly and reduce the efforts to find the source of the errors. In addition, we present a method for checking the feasibility of the synchronized method sequence to be replayed.

The purpose of this study was to investigate whether or not the use of the Korean alphabet increased the accuracy of English sentences Korean university students produced in dictation. The students were divided into three categories, beginning, intermediate, and advanced, based on the listening comprehension scores of a practice TOEIC test. The total population of 120 students were divided into two groups, control and experiment. In the first testing, the experiment group transcribed the English utterances on a practice TOEIC tape into phonological writing in Korean and then later changed the Korean writing into English words and sentences. In the second testing, the control group became the experiment group and used the Korean alphabet in transcribing the English sounds. Statistically significant differences were found in the improvement of accuracy in dictation when the Korean alphabet was used, especially for the beginning and intermediate students. By using the Korean alphabet as the phonological representation of the sounds, the students in the experiment group produced more accurate English words than the control group who went directly from the English utterances to writing in English. Statistically significant results were not produced for the advanced students. The significance of the present study relates to the need to add to the paucity of available data on the use of the Korean alphabet in teaching listening comprehension.

Nowadays, as the development paeiod of new products becomes even shorter, the importance of Rapid Prototyping Technology(RPT) has been rapidly increased. The major application of RPT is an early verification of product designs and quick production of prototypes for testing. Moreover, RPT is applied not only as a second tooling process such as mold making and investment casting but also as a creating some physical structure in medical field. Despite the remarkable progress of RPT, it is required to improve various problems resulting from application such as production time, accuracy and materials. This paper presents a laser scan path generation for accuracy of stereolithographicparts The methodology of laser scan path generation is discussed based on the stereolithography, The procedure of this research is as follows : 1) Input laser scanning conditions such as a laser beam diameter and a laser scanning interval, 2) Reconstruct original contours without self intersecting offset, 3) Calculate offset about reconstructed contours, 4) Calculate intersection points between horizontal or vertical lines and offset contours for internal hatch, 5) Decide laser shutter on/off points. The algorithm developed and programmed by C language is verified as an efficient method after testing a number of STL files of mechanical parts.
