In this paper, I first examine Reiss'(2005) arguments for the causal instrumental variable. Second, I argue that the conditions for causal transitivity I consider meet what the causal instrumental variables and the interveners of the manipulation theory of causation are intended to hold. Reiss shows that two conditions for instrumental variables are not sufficient for causal significance of independent variables for dependent variables. Reiss articulates and reformulates the conditions for instrumental variables in terms of the conditions on causality, while naming his instrumental variables as causal instrumental variables. Reiss argues that the causal instrumental variables are similar to the interveners of the manipulation, or intervention theory of causation. He further argues that the causal instrumental variables do a better job the interveners do. I argue that the conditions for causal transitivity I consider meet the goal the conditions for the causal instrumental variables and the conditions for the interveners both are intended to achieve.

This paper makes an attempt to look at the process of automatically generating an application software system based on the Entity-Relationship (E-R) model. Basically, the process consists of five steps as follows: First, the designer develops an E-R model of an real-world system. Second, the software generator automatically generates a stereo-type application system. Third, the generator produces database schema and link information between application programs. Fourth, the designer designs the user interface including menu, screen design and so on. Finally, the generator completes the process integrating all the elements of an application system. Five basic program generation rules, three extended rules and a database generation rule have been suggested. By following each rule with the generator, the designer can build an application with an extremely efficient manner compared with traditional approaches. A case study has been included in order to show the applicability of the automated software generation process suggested in this paper. It has been demonstrated from the case study that the idea of applying an automated generator in systems development based upon the E-R model worked well.

History centered knowledge based story-telling project planning tool supports the process of story creation in narrative genre about history of families or individuals. Narrative fields not only include drama, mythology, legend, history but also non-verbal epics such as movie, play, ballet and opera. But as verbal epic, this research paper focuses on the family history and individual history of each household. This story-telling planning tool redevelops each genre of story-telling about family history through sampleDB and informationDB, and it is widely applicable in concreting high quality stories in both its content and value. Reduces the time of planning story-telling, and impose minimum expenses in human resources. Content about family history is one of the most the fundamental and renowned contents in Story-telling but planning tool that is easily applicable in creating such content does not exist in statue quo. In this current system lacking creative infra, this research paper seeks to provide a planning tool that public can easily utilize, and by systemizing the tool. it aims to create a creative contents tool model applicable in variety of genres.

This study aimed to develop a self-reporting assessment tool for digital literacy competence to use it as a tool for self-diagnosis or effectiveness verification in educational programs, considering that digital literacy competence is one of the core competencies for the present and future society. Based on the previous research on digital literacy competence, the tool was developed with 45 question items of 2 areas and 8 factors. The results of an exploratory factor analysis and confirmatory factor analysis conducted to determine suitability were generally satisfactory based on the assessment data from about 3,000 middle school students. The assessment tools developed in this study are primarily applicable to primary and secondary school and adult education. In future research, if the system is developed to be accessible to anyone online based on this tool, and the accumulated data provide educational information for each individual's self-development, it will greatly contribute to improving the digital literacy competence of the people.

In order to reduce the possible quality problems in the construction stage. This research will develop a quality management support tool based on Mobile BIM. In order to develop the tools of this study, the procedures of domestic quality management work were analyzed, and 12 functions were derived to solve the existing problems, and the process of mapping checklists by work type and BIM model objects was performed. Finally, through the questionnaire survey on the usefulness of the tool in the actual field, the possibility of props in actual supervision business is verified.

모바일 어플리케이션 개발자들은 센서를 활용하여 사용자를 위한 맞춤화 서비스를 제공하고 있다. 센서를 활용한 어플리케이션은 다른 소프트웨어와 마찬가지로 더욱 높은 품질을 위해 테스트를 필요로 한다. 그러나 기존의 모바일 어플리케이션을 위한 테스트 도구들은 센서에 대한 접근성, 센서 데이터 입력, 전력 소모에 대한 비고려 등의 문제를 갖고 있어, 동적 테스트를 수행하는데 사용하기에는 한계를 지니고 있다. 물론, 이러한 문제를 해결하기 위해 여러 연구들이 진행되어 왔지만 기존의 연구들은 일부의 특성만을 반영한 테스트 도구를 개발하였거나, 기법만 개발하였다. 따라서 본 논문에서는 이러한 특성들을 통합적으로 반영한 동적 테스트 도구를 개발하기 위해 센서를 활용한 어플리케이션의 특성을 도출하고, 이를 이용하여 기존의 동적 테스트 도구들의 한계점을 분석하였다. 그 후, 이를 기반으로 하여 동적 테스트 도구의 요구사항을 도출하였다. 그 결과, 총 3개의 특성과 5개의 한계점 그리고 6개의 요구사항을 도출하였다. 향후 본 논문은 센서를 활용한 어플리케이션을 위한 동적 테스트 도구의 개발에 기초가 될 것이다.

The purpose of this study was to develop a disaster nursing competency scale for nursing students. 23 preliminary items were selected by classifying 44 disaster nursing core concepts extracted via literature review. Content validity was done by expert panel. In order to verify the reliability and validity of the preliminary instrument, data were collected from 270 nursing students in 2 colleges of nursing in Korea. One factor 11 items in disaster nursing skills and one factor 11 items in disaster nursing knowledges were extracted by factor analysis. This instrument may be useful to identity a disaster nursing competency and its related factors for nursing students.

There is little study related to the 3D convergence contents authoring tool for teacher. In this study, we purposed the design of the interactive 3D convergence contents authoring tool for a teacher. To draw the design, firstly, we investigated the authoring environment of teachers and interviewed teachers. Based on this investigations, we proposed the functional requirement and UI/UX(User Interface/User Experience) design of it. And we investigated the level of focusing group satisfication with the UI/UX design. Based on these results, we will implement the authoring tool.

Many archives, including the National Archives of Korea, use online finding aids. However, in many aspects, they need improvement. In this study, with focus on the National Archives of Korea, the online finding aids of the National Archives of Australia (NAA), The National Archives (TNA) of United Kingdom, and the National Archives and Records Administration (NARA) of the United States were analyzed. Focus group interview was administered to users of the archives, identifying the pros and cons of online finding aids of NAA, TNA, and NARA. Based on the results, various improvement and development directions are suggested, including aspects on overall functions and hierarchical search, search options and subject search, representing search results, and archival contents services.

The purpose of this study is to develop a test tool that can be measured in various aspects for the reading attitudes of children. For that it was set the configuration based on the preceding reading attitude survey and models and tacit knowledge of attitude toward reading and wrote the questions for reading attitudes. It conducted a primary and secondary test for elementary school students in grades 4-6 to verify the validity and reliability of measurement tools. 8 factors of the reading attitudes measurement tool were extracted through exploratory factor analysis and it described 66.29% of total variable. the r-value for inter-item consistency about reading attitudes were above 0.4 on all questions. The Cronbach ${\alpha}$-value of reliability coefficient about reading attitudes measurement tool was 0.950. Therefore Reading attitude test tool have reading usefulness, reading efficacy, leisure, stiumulation, flow, expression, study, assertiveness as sub factors of reading attitude has been shown that it can serve as a useful tool for measuring various aspects of the reading attitude for children.
