This article presents a case study in which three middle school students developed models in modeling activity using a tool. We research the interaction of model development process and the activities operating a tool in the modeling. And we investigate whether students are able to create generalizable model, after a tool mediates students' thought process and students internalize the perceptive activity operating a tool. The analysis of our case study led to three results. First, as students were able to integrate perceptive activity operating a tool and cognitive activity, they reasoned about the relationships among changing quantities and developed the model. Second, students corrected and refined developed models with reflecting the perceptive activity operating a tool. Third, as students internalized perceptive activity, students were able to create generalizable model, which is a graph of height as a function of the amount of water that's in the beaker.

The purpose of this study was to investigate the reliability and the validity of the Korean Occupational Stress Scale(KOSS) in occupational therapists. The data were collected from 214 occupational therapists by using the Korean Occupational Stress Scale. The gathered data were conducted the factor analyses and validation process to ascertain the validity. The results of this study suggested that to estimate occupational stress of occupational therapist, modified version of the KOSS which was consist of eight subscales might be more an appropriate measurement scale than the original version of the KOSS which was composed of seven subscales. Eight subscales of the scale were occupational climate, organizational system, insufficient job control, lack of reward, job demand, interpersonal conflict, job ability and job insecurity, and out of these, job ability was newly added for occupational therapist. Also the results indicated that Cronbach's alpha score of this measurement tool was 0.84, and it means that internal consistency of this scale has good reliability, and the number of questions are also valid. This study has significance to suggest necessary psychometric characteristics of the occupational stress scale for job stress study in occupational therapist.

Recently, in automotive industry, there have been many researches related with hardware components and embedded software which controls hardware components. Since most of embedded software is tightly dependent on car manufacturers, there were some problems in reusability and interoperability of automotive software. In order to solve these problems, AUTOSAR standardized the component-based software architecture of automotive software. In AUTOSAR, several modeling diagrams should be described and their dependencies are also checked. Currently, a few company developed the prototypes of tools supporting AUTOSAR. In this paper, a component modeling tool based on AUTOSAR 3.0 is developed for enhancing the usability of existing tools using Eclipse GMF. The tool is composed of a graphical component modeling tool and a graphical network topology tool. Since these tools are generated based on GMF without hard coding, it is relatively easy to customize the tools for adopting company‘s needs and easy to follow the improvement of the standard and development environments.

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.

As new database systems are developed or new functions are added to existing database systems, database developers or users would like to evaluate new database systems or new functions. This paper presents an integrated database benchmark suite. The integrated suite offers genetic benchmarks, custom benchmark, and hybrid benchmarks to users on a unified Web user interface. With regard to text data generation, the integrated suite supports eight data distributions with three data types. The integrated suite can also generate XML data in three different ways. Users can run benchmarks in realistic environments by performing the workload generation facility of the integrated suite, which generates composite workloads similar to real-world workloads. Using supporting tools, users can easily implement new generic and custom benchmarks in the integrated suite. An illustrative demonstration to add a new custom benchmark into the integrated suite is presented.

This study investigeted secondary math teachers' difficulties of technology in geometry class with grounded theory by Strauss and Corbin. 178 secondary math teachers attending the professional development program on technology-based geometry teaching at eight locations in January 2014, participated in this study with informed consents. Data was collected with an open-ended questionnaire survey. In line with grounded theory, open, axial and selective coding were applied to data analysis. According to the results of this study, teachers were found to experience resistance in using technology due to new learning and changes, with knowledge and awareness of technology effectively interacting to lessen such resistance. In using technology, teachers were found to go through the 'access-resistance-unaccepted use-acceptance' stages. Teachers having difficulties in using technology included the following four types: 'inaccessible, denial of acceptance, discontinuation of use, and acceptance 'These findings suggest novel perspectives towards teachers having difficulties in using technology, providing implications for teachers' professional development.

Baseboard Management Controller(BMC) supports server monitoring, maintenance, and control functions using various communication interfaces. However, if an unexpected problem occurs during the device driver initialization process, the BMC may not operate normally. Therefore, a boot process profiling tool that accurately analyzes the device driver initialization process and provides a function to check the analysis result is essential. Existing boot process profiling tools do not specifically provide the device driver initialization process and results required for BMC boot process analysis, forcing developers to use a combination of tools to analyze the boot process in detail. In this paper, we propose an integrated profiling tool for BMC's booting process. The proposed tool provides device driver initialization process analysis, CPU and memory usage analysis, and kernel version management functions. Users can easily analyze the booting process using the proposed tool, and the analysis result can be used to shorten the booting time. Also, the proposed tool is implemented in Linux-based BMC, and it is shown that the proposed tool is more efficient than the existing profiling tool.

Objective: The purpose of this study is to analyze comprehensive lifestyle assessment and other assessments which evaluate essential lifestyle factors, including physical activity, nutrition and activity participation. Methods: To analyze the comprehensive lifestyle assessment, from January 2001 to June 2019, a literature search was conducted using the CINANL, NDSL, PubMed, and RISS databases. The search terms were 'lifestyle assessment' OR 'lifestyle profile' OR 'lifestyle test'. In terms of other assessments of essential factors of lifestyle, from January 2010 to June 2019, articles were searched using similar databases. The search terms were 'physical activity assessment' OR 'physical activity participation profile', 'nutrition assessment', 'activity participation assessment' OR 'activity participation and lifestyle'. Results: A total of 4,165 articles were obtained, and finally 31 articles were selected according to the inclusion criteria. Among 31 articles, there were five with comprehensive lifestyle assessments, and all of them were self-report questionnaires. The most popular assessments were the Health Enhancement Lifestyle Profile (HELP) and the Health-Promoting Lifestyle Profile (HPLP), which were used in three articles (33%). In terms of assessment of physical activity, the most frequently used evaluation method was the self-report questionnaire, which was used in seven articles (58%) followed by objective assessments, which were used in four articles (33%). It was demonstrated that the Mini-Nutritional Assessment (MNA) was the most frequently used for nutrition assessment in the elderly. There were five types of assessment tool used for activity participation. Among them, meaningful activity participation assessment (MAPA) was the most frequently used tool. Conclusion: As a result of the systematic review, it was found that there are 21 assessments related to the evaluation of lifestyle in the elderly. Most assessments employed the self-report questionnaire method and mainly evaluated frequency and duration of participation in drinking, smoking, exercise, nutrition and social activities. Assessments of essential lifestyle factors were the self-report questionnaire method and the participation and frequency of activity. Therefore, by analyzing assessment tools, types of items and measurement methods of comprehensive lifestyle assessments and other assessment of essential lifestyle factors, this study provides the basic data on which to develop a standardized assessment tool that can evaluate the multifaceted lifestyle profile of the elderly.
