Quality of the software is affected by quality of data required for operating the actual software. Especially, it is important that assure the quality of data in a knowledge-engineering system that extracts the meaningful knowledge from stored data. In this paper, we developed DAQUM tool that can measure quality of data. This paper shows: 1) main contents for implement of DAQUM tool; 2) detection of dirty data via DAQUM tool through case study and measurement of data quality which is quantifiable from end-user's point of view. DAQUM tool will greatly contribute to improving quality of software product that processes mainly the data through control and measurement of data quality.

다양한 재난안전 유관기관으로부터 생산 및 관리되는 재난안전정보는 공유를 통해 재난관리업무를 보다 효율적이고 신속하게 수행할 수 있도록 도와준다. 그러나 재난안전정보 공유를 위해서는 우선 재난안전 분야에서 사용되는 용어의 표준화 및 체계화가 선행되어야 한다. 특히 다양한 분야에서 축척된 용어들을 모두 종합 검토하고 형상 관리하기 위해서는 별도의 구축도구가 필요하다. 본 논문에서는 재난안전정보 용어사전 구축도구를 통해 재난안전 분야의 용어를 입력하고 정제 및 검토하는 과정을 통하여 용어 표준화를 수행하고자 한다. 특히 본 논문에서 개발된 구축도구는 웹 기반 다중접속이 가능하도록 구현되었고, 하나의 표제어에 다양한 정의문이 할당되는 일대다 관계로 용어사전을 관리하고 있어 다양한 분야에서 혼재되어 있는 정의문들을 종합적으로 관리할 수 있다는 장점이 있다. 현재는 개발된 구축도구를 활용하여 재난안전정보 용어사전을 구축 중에 있으며, 차후 구축된 용어사전을 재난안전 분야 실무자 및 일반 이용자에게 제공하기 위한 활용도구 구축 연구가 추가적으로 진행될 계획이다.

The purpose of the paper was to develop an observation measure for analyzing the teaching and learning activities in ubiquitous-based learning. To develop the measure, we reviewed the literature related to the measure and identified the valid observation domain and indicators. In the procedure, we did a pilot study for validating the measure and its indicators, and in the end, finalized it. The observation measure consists of: types of instruction, teaching and learning strategies, learning activities, use of technology, evaluation process, and wrap-up. In addition, we added the qualitative domain, which needs for monitoring and writing more specific teaching and learning activities in ubiquitous-based learning.

We have developed software for the SMFD that utilizes a range of graphic design tools. These tools enable us to effortlessly create graphic elements by defining their attributes, such as position and motion. Subsequently, we can convert these designs into source code and execute the resulting software on the target system, leveraging the graphic engines provided by the tools. However, when it comes to developing the displaying software for the SMFD using multiple graphic design tools on a single system, we face various challenges. In this paper, we will delve into these challenges and propose solutions for developing the displaying software for SMFD based on heterogeneous display design tools.

The early detection of suicidal ideation is essential for the prevention of suicide. This study aimed to develop a brief screening tool that can be easily administered in medical settings. The Suicide Risk Screening Tool was designed for use by physicians to provide a screening process that would be reliable, standardized, quick and feasible to implement. A 2-item screening tool was derived from the Screening for Depression and Thoughts of Suicide in the Norton Sound region of Alaska, USA. The scale was modified to reflect the current situation in Korea including the elimination of the personal identification number, and was labeled the Korean Suicide Risk Screening Tool. Its reliability and applicability for medical setting were examined by explanatory study of 7 clinicians. Its validity was examined among a further 325 patients of four different medical institutions, using the results of interviewer-administered survey included demographic, clinical characteristics, and present mental status as the external criterion. A brief 2-item suicide risk screening tool can be used by mental and non-mental health clinicians to accurately detect suicidality in patients.

This study develops and examines the validity of a Creativity Test for children from of 4 to 7. 47 items were constructed through the validity of the literature and expert's content validity. The results of this study consisted of 22 items with three factors. These factors are flow and independence, expansion of thinking, curiosity and openness. The tests scale was examined about item's response distribution, item's discrimination, and construct validity and internal consistency reliability, and it was adoptable. It can be concluded that the test tool developed in this study is suitable for measuring the creativity of Korean children from 4 to 7 years in a simple manner, and it measures relatively well the cognitive and affective characteristics of creativity. Creativity test tool for children from 4 to 7 years in this study will contribute to the active progress of research on creativity for young children and elementary school children.

The purpose of this study is to construct two equivalent science relevance recognition test tool after confirming the reliability and validity of the CARS(Changes in Attitude of Relevance to Science) questionnaire to determine the applicability of the items to Korean students and to compare gender and school differences. For this study, 59 items of the CARS scientific relevance test were translated and assigned to 787 middle and high school students (analyed the answer of 300 middle school students and 431 high school students). In order to determine the fit of the CARS question to Korean students and to overcome the limitation of the number of questions, we used the item-linking method of the Rasch model. By analyzing the results of the research, we constructed two equivalent scientific relevance recognition questionnaires of CARS-A and CARS-B with 25 items. The Pearson correlation coefficient of the Rasch scores of the two equivalent test was 0.78. The two types of scientific relevance recognition test tools generated through this study can be used to confirm students' attitude of scientific relevance to daily life, or to confirm the change after a certain class or grade. Through this study, we will discuss the implications of students' perceptions of science associations in science education, and the development and application of tools.

There is a lack of user centered design methods that support effective collaboration between designers and end-users for designing hardware and software integrated digital products. This paper presents the application of Collaborative Design and a new collaborative design prototyping tool for interactive digital product design projects. The tool consists of STCtools(State Transition Chart tools) software, hardware modeling materials, and physical interface toolkits for integrating software and hardware. STCtools allow users to create and edit States, to compose Events describing transitions between States, and to run intermediate or final results of STC. Using the hardware modeling materials and the physical interface toolkit, designers and end-users can collaborately examine the hardware and software integrated concepts in an early stage of the design process. Three collaborative design workshops of designing a portable digital guide for a theme park were accomplished to examine the feasibility of the tool. The results suggested that the tool supported iterative concept development and interactions between designers and end users. Although several user interface problems of STCtools were identified, the participants gave positive feedback on the role of the tool in collaborative concept generation and deployment. It is expected that the results of this study contribute not only to the collaboration between designers and end users, but also to the collaboration between designers, and between designers and other professionals.

본 논문에서는 실시간으로 변하는 사용자의 컨텍스트를 고려하여 재구성되는 사용자 인터페이스를 제공하기 위한 인터페이스 제공 시스템 및 저작 도구에 관한 기술을 소개한다. 차별적 서비스를 제공하기 위해서 사용자가 컨텐츠를 소비하고 있는 시점에서의 컨텍스트를 해석하고 이를 반영한 유기적이고 적응적인 사용자 인터페이스를 제공할 수 있어야 한다. 사용자 인터페이스를 반응적으로 구성하고 이를 저작하는 도구에 대한 연구는 웹 기술의 발전과 함께 오랜 기간에 걸쳐 연구되었지만 단순 서비스 조합이나 물리적 GUI 생성에 관한 연구가 주를 이루고 있고 표준화된 컨텍스트와의 유기적 연결성을 고려한 연구는 사례 연구 정도에 머물러 있다. 본 논문에서는 웹을 기반하여 세부 기술에 대한 이해 없이 컨텍스트 기반 사용자 인터페이스를 구성하고 서비스 할 수 있는 시스템과 저작 도구에 대해 소개하고 향후 연구 방향에 대해 논의한다.
