컴퓨터 테크놀로지의 발전으로 컴퓨팅 환경이 모바일 기기 기반으로 급속히 바뀌어가고 있다. 지금까지 디지 털 리터러시 교육은 데스크 탑 PC 기반의 교육이 이루어졌으나 이를 모바일 환경에 맞는 리터러시 교육으로 변 화가 필요한 시점이다. 본 논문에서는 모바일 기기의 특성을 가진 모바일 기반 디지털 리터러시 MoDL(Mobile Device Digital Literacy) 교육 체재를 제안한다. MoDL을 3단계로 구축하여 모바일 디지털 환경을 구축하는 MoDE(Mobile Based Digital Environment)와 이를 교육에 활용할 때에는 BYOD(Bring Your Own Devices) 수 업 방식을 제안한다. 마지막으로 모바일 디지털 리터러시를 학습하는 MoDLI(MoDL Instruction)을 단계별로 제 시한다. 제시된 MoDL 교육 체재에 대한 타당도를 검증하기 위하여 전문가 8인에게 설문조사를 실시하여 내용 타당도 비율(Content Validity Ration: CVR)을 산출하였다. 그 결과 MoDLI의 현장 적용성을 제외한 모든 항목 에서 내용타당성을 확보하였다.

The computing environment is rapidly changing to mobile device base, with the development of computer technology. Until now, digital literacy education has been based on desktop PC education, but it is time to change it into literacy education suitable for mobile environment. In this paper, we propose a mobile-based digital literacy MoDL (Mobile Device Digital Literacy). MoDL proposes three phases. One is Mobile Based Digital Environment (MoDE), which builds a mobile digital environment, seconds is Bring Your Own Devices (BYOD) class method when using it for education. Finally, MoDLI (MoDL Instruction) for learning mobile literacy is presented step by step. To verify the validity of the proposed, eight experts were surveyed so that the Content Validity Ratio was calculated. As a result, CVR was ensured in all items except for the applicability of MoDLI.

Lee, Y. H., & Jeong, K. (2007). Process, translator roles and tools of software localization. Conference Interpretation and Translation, 9(2), 133-153. Software localization process can be largely divided into two features: linguistic and non-linguistic. The non-linguistic features include the basic process of localization, work flow, software translation tools as well as the engineering aspects of localization. The paper looks at the three main stages of localization – internationalization, translation, and localization stage using examples, presents a localization work flow chart, describes the roles that translators may play and provide samples of translation tools most often used in the market. The aim of the paper is to provide information that the two authors deem helpful in understanding the concepts of software localization. Keywords: internationalization, translation, localization, user interface, documentation

교육이 효과적으로 이루어지기 위해서는 교육대상자들에 대한 평가가 적절하게 이루어질 필요가 있다. SW 교 육의 효과성을 높이기 위해서는 교육에 대한 학생의 만족도를 분석하고, 그 결과를 바탕으로 교육과정을 재구성 할 필요가 있다. 이에 본 연구에서는 SW 교육에 대한 학생들의 만족도를 정확하게 측정할 수 있는 SW 교육 만 족도 측정 도구 개발을 설계하고 진행하였다. 만족도 측정 도구의 범주 및 문항을 개발하고 전문가 검증 및 AHP 분석을 통해 타당도를 검증하였으며, 예비 검사를 통해 최종 문항을 선정하였다. 본 연구를 통해 SW 교육 만족 도를 측정할 수 있는 도구를 개발하였으며, 이를 통해 유의미한 교육 설계에 도움을 줄 수 있을 것이라 기대한다.

In order for education to be effective, it is necessary to properly evaluate the subjects. In order to increase the effectiveness of SW education, it is necessary to reconstruct the curriculum by analyzing the students' satisfaction with education and refluxing the results. Therefore, this study designed and developed the SW education satisfaction measurement tool to accurately measure students' satisfaction with SW education. The categories and items of satisfaction measurement tools were developed, validity was verified through expert verification and AHP analysis, and final items were selected through preliminary examination. Through this study, we developed a tool to measure the satisfaction of SW education, and it is expected that it can be helpful for meaningful education design.

As the number of data and devices explodes, centralized data processing and AI analysis have limitations due to the load on the network and cloud. On-device AI technology can provide intelligent services without overloading the network and cloud because the device itself performs AI models. Accordingly, the need for ondevice AI technology is emerging. Many smartphones are equipped with On-Device AI technology to support the use of related functions. In this paper, we compare software tools that implement On-Device AI.

There are different models and methods in the literature that assess risks in software projects. But few of these models and methods propose visualized software risk assessment tools that help project managers to visually identify, analyze, and prioritize risks in software projects. In this paper, a summary of these tools are presented with a detailed explanation of the strength and weaknesses of these software risk assessment tools that are found in the literature.

Software testing is the major challenge of complex software systems. In this field, accuracy and running time are two major performance factors frequently employed to evaluate the reliability of software testing. Automated software testing is a technique which significantly improves these performance factors. There are various automated testing tools dealing with design features however this paper focuses on the comparison of the testing tools exclusively used for .Net applications. We attempted to search for high performance testing tools including popular software testing environments so that the obtained results can be extended to a wide domain of software developers. The main goal of this paper is to analyze and compare the automated software testing tools using practical examples and review the performance of these tools in terms of software reliability determination.

Corpora are often referred to as the ‘tools’ of corpus linguistics. However, it is important to recognize that corpora are simply linguistic data and that specialized software tools are required to view and analyze them. The functionality offered by software tools largely dictates what corpus linguistics research methods are available to a researcher, and hence, the design of tools will become an increasingly important factor as corpora become larger and the statistical analysis of linguistic data becomes increasingly complex. In this paper, I will first discuss how separating the data from the tools resolves various issues that are hotly debated within the field. Next, I will offer a critical look at the development of four generations of corpus tools, discussing their strengths and weaknesses. Then, I will discuss the role of programming in corpus linguistics tools creation and present a model for the development of future corpus tools. Finally, I will show a real-world example of a next-generation corpus tool that was developed for use in language learning.

There exist a number of information systems planning(ISP) methodologies. As the level of market competition gets intensified, firms are more likely to engage in organizational transformations such as BPR and CPI(continuous process improvement). Because this new requirement should be incorporated into ISP methodology, the number of ISP methodologies available will be continually increasing. However, we could not find a framework for understanding and classifying these divergent methodologies. So, we here present a framework for classifying ISP methodology classes. With this framework, we categorize different classes of ISP methodologies and identify their limitations in terms of missing elements and links. And we move on to present new technical innovations and other methodological advances that, if properly integrated with ISP methodologies, would help us derive an IT infrastructure plan more effectively. Furthermore, in search of software tools or aids supporting the application of ISP methodologies, we identify requirements of ISP-supporting software tools and evaluate functions of existing software tools, then suggesting a future direction to that end.

Increased use of software and complexity of software functions, as well as shortened software quality evaluation periods, have increased the importance and necessity for automation of software testing. Automating software testing by using machine learning not only minimizes errors in manual testing, but also allows a speedier evaluation. Research on machine learning in automated software testing has so far focused on solving special problems with algorithms, leading to difficulties for the software developers and testers, in applying machine learning to software testing automation. This paper, proposes a new machine learning framework for software testing automation through related studies. To maximize the performance of software testing, we analyzed and categorized the machine learning algorithms applicable to each software test phase, including the diverse data that can be used in the algorithms. We believe that our framework allows software developers or testers to choose a machine learning algorithm suitable for their purpose.

성공적인 소프트웨어 개발 환경을 구축하기 위하여 도구 사이의 인터페이스가 잘 정의되어야 한다. 최근에 활발히 연구되는 CASE 도구들이 잘 결합하여 일관성있는 환경이 되기 위해서는 자료 저장소의 설계가 중요하다. 특히 요지보수를 위한 도구 개 발은 원시 코드의 변경과 프로그램으로 표현된 객체들 사이의 상호관계를 잘 나타내도 록 자료 저장소를 설계하여야 한다. 본 논문에서는 소프트웨어 유지보수 환경 구축에 필요한 자료 저장소 설계에 통합 방법을 도입하였다. 유지보수 대상 객체들을 정의하 고 객체들 사이의 관계를 나타내었으며 자료 저장소를 접근하기 위한 방법도 제안하 였다. 이 방법에 의하면 유지보수하는 동안 변경을 관리하기 위한 버젼 및 현상관리 뿐만 아니라 질의 서비스, 자료교환 서비스가 효율적으로 이루어진다.

It has been commonly accepted for a while that a successful tool environment must provide for smooth interfaces between its tools. Recent integrated CASE environment must be-based on well-integrated data repository which supports a tightly coupled, consistent environment. For the maintenance tool, it requires a careful design of the maintenance chest's database. Information about a program exists in many different forms after analyses have been performed. It must be possible to associate and select objects for data repository from this information as necessary. This paper suggests a new integrated scheme for the data repository in building software maintenancec environment. The scheme provides many basic services, including storage and management of objects/entities and links/ relations; version and configuration control, query service, data interchange service.

The purpose of this study was to explore how designers use software-based design tools for ideation and collaboration (for two cases: with designers and with developers). We conducted logistic regression analysis and random forest analysis. Software-based design tools are more popular among product designers and affiliated with design organizations with 51 to 100 members. We identify the features that influence designers to use design tools for the ideation and collaboration, and how these usage patterns are interrelated. Interrelated usage pattern is a key consideration for location of the menu and convenience of use. The results imply that reinforcement of the design tool features per designer profile is required and that design management should be consistent with the field of design and the nature of the organization.

Although many tests for stabilization of the software have been done, vulnerability test for a system run by combination of the software of various products has not been conducted enough. This has led to increased threats and vulnerability of system. Especially, web-based software system, which is public, has inherent possibility of exposure to attacks and is likely to be seriously damaged by an accident. Consequently, comprehensive and systematic test plans and techniques are required. Moreover, it is necessary to establish a procedure for managing and handling the results of vulnerability test. This paper proposes vulnerability test plans and designs for implementing automated tools, both of which can be complied with on web-based software systems.

Software linear and exponential acceleration/deceleration algorithms for control of machine axes of motion in industrial robots and CNC machine tools are proposed. Typical hardware systems used to accelerate and decelerate axes of motion are mathematically analyzed. Discrete-time state equations are derived from the mathematical analyses for the development of software acceleration/deceleration algorithms. Synchronous control method of multiple axes of motion in industrial robots and CNC machine tools is shown to be easily obtained on the basis of the proposed acceleration/deceleration algorithms. The path error analyses are carried out for the case where the software linear and exponential acceleration/deceleration algorithms are applied to a circular interpolator. A motion control system based on a floating point digital signal processor (DSP) TMS 320C30 is developed in order to implement the proposed algorithms. Experimental results demonstrate that the developed algorithms and the motion control system are available for control of multiple axes and nonlinear motion composed of a combination of lines and circles which industrial robots and CNC machine tools require.

RFID 기술의 발전으로 태그 가격이 급속도로 낮아짐에 따라, 더 세밀하게 제품을 관리하기 위해 각 태그가 포장상자에만 부착되는 것이 아니라 개별 제품에 부착된다. 그러나 RFID 데이터를 처리하는 판독기와 미들웨어가 한정된 하드웨어 자원을 가지고 있기 때문에, 초대용량의 태그 데이터를 신속하게 처리하기 위한 방법들이 필수적이다. 본 논문에서는 이러한 요구조건을 효율적으로 충족시키는 새로운 이동 에이전트 기반 분산형 소프트웨어 도구를 설계하고 구현한다. 이 도구는 명시된 데이터 수집 정책을 포함한 이동 에이전트를 다수의 이동식 판독기들로 전송함으로써, 필요한 데이터가 제품의 운송 중 반복적으로 전 처리 될 수 있도록 하는 편리한 환경을 제공한다. 이러한 수행 형태는 목적지에 도착한 후 매우 많은 양의 태그 데이터를 고정식 판독기에서 처리하는 기존 방식에 비해, 판독기와 미들웨어에서 매우 높은 인식률로 태그 데이터를 처리하기 위해 요구되는 소요시간을 상당히 줄일 수 있다.

As RFID tag prices have rapidly been declining because of the advance of RFID technology, each tag is attached to an individual item, not a packing box only, for managing the item much more precisely. However, some mechanisms are essential to handle a very large amount of tag data quickly because readers and middlewares processing RFID data have limited hardware resources. In this paper, we design and implement a new mobile agent-based distributed software tools to satisfy this requirement efficiently. These tools provide a convenient environment enabling required data to be pre-processed repeatedly in transit by transferring a mobile agent including its specified data collection policy to numerous mobile readers. This behavior can significantly reduce the elapsed time required for processing huge volumes of tag data at the readers and middlewares with their very high recognition rates compared with the existing one to process the data by fixed readers after having arrived at the destination

본 논문에서는 국내외 선진회사의 SCL 엔지니어링 툴에 관한 연구를 진행하였다. 최근 전력산업이 디지털화 되면서, 변전소자동화에 관련된 국제 표준인 IEC61850은 필수 요소로 자리 잡았다. 따라서 IEC61850 표준에서 사용하는 SCL파일들을 생성, 수정하고, 각종 서비스들을 규정하는 SCL 엔지니어링 작업은 필수적이다. 하지만, 현재 벤더중심, 해외위주의 엔지니어링 툴만이 대부분이기 때문에 국내 실정에 맞는 디지털변전소 엔지니어링 툴을 개발하는 것이 시급하다. 따라서 본 연구는 여러 가지 관점에서 선진 툴들을 분석하고, 분석내용을 토대로 SCL 엔지니어링 툴의 필수 기능들을 도출하고, 사용자 중심의 편의성 높은 엔지니어링 툴을 설계하는 것을 목표로 한다.
