The purpose of this study was to develop the Job Functional Assessment Scale. This study was involved took third steps. First, 93 preliminary items were developed based on theoretical literature and International Classification of Functioning, Disability and Health (ICF) Model. To verify the content validity, 3 rehabilitation experts rated those items. Second, the scale consisting of 73 items was administered to sample of 880 people with disabilities. Finally, items of the scale were reduced to 58 items. Factor analysis showed evidence of construct validity of the scale. Internal consistency (Cronbach's ${\alpha}$) of total score showed .94 and Cronbach's ${\alpha}$ of 7 subfactor demonstrated .74~.90. Thus, Job Functional Assessment Scale demonstrated satisfactory convergent validity and discriminant validity. In addition, the practical use of the scale was discussed.

소프트웨어 시스템의 대형화와 복잡화에 따른 소프트웨어 특징의 식별, 분류를 위한 프로그램 복잡도 측정에 대한 연구들이 수행되어 왔다. 그러나 하나의 인자를 이용한 복잡도 척도나 인자에 대한 중요도의 명확한 제시가 없는 다수의 인자를 이용한 혼합적 척도는 복잡도를 정확히 측정 평가할 수 없다. 따라서, 본 연구에서는 현업에서의 연구와 경험을 통해서 증명된 객관성 있는 척도들과 각 척도들의 중요도를 가중값으로 하여, 기능 중심으로 구성된 프로그램의 복잡도를 측정할 수 있는 새로운 혼합적 척도를 제안한다.

DRM software should conform completeness, correctness and appropriateness for the related function to protect digital right properly. Therefore, the systematization of functionality evaluation method based on the related standard is essentially required. In this paper, based on the software quality standard, I intended to construct a model to measure the quality about functionality including suitability, accuracy and interoperability of DRM software. To this, we developed functional suitability evaluation model by analyzing infra-technology of DRM software and quality requirements about functional suitability. I think that through this study, functionality criteria to enhance the quality level of DRM software. Through the accumulation of future evaluation practices, it is necessary to improve the suitability and validity of the DRM software functional suitability evaluation model.

Poststroke depression can have a secondary effect on social cognition, and this can lead to behavioral problems. The purpose of this study was to verify the effects of a Cognitive Stimulation Circulative Program(CSCP) based on occupational therapy. The participants of this study were 12 stroke patients. The CSCP was organized in such a way to promote the cognitive process. This program were carried out as a circuit program(16 sessions). As a result of this study, the depression scale of the subjects had statistically significant benefit(p<.05). Also, the evaluation results verified partial improvement in quality of life, and the relationship change scale which was used to evaluate role of physical and social cognitive function ability had statistically significant benefit(p<.05). The above results of this study verified that the CSCP was an efficient intervention program that reduces the depression of stroke patients and improve their social cognitive function ability, thus enhancing the quality of life.

The purpose of this study was to investigate the effects of virtual reality game based training on balance and upper limb function in subacute stroke patients. Thirty patients with subacute stroke were randomly assigned to experimental groups(n=15) and control groups(n=15) applying virtual reality game-based training programs. Intervention is applied three times a week for 6 weeks, 30 minutes for 1 time. In the study group, there was a significant improvement in balance ability, upper extremity function, and trunk impairment scale(p<.05), and the difference between the two groups was significant in the BBS, TUG, TIS(p<.05). Based on these results, the virtual reality game based training program is clinically useful exercise program for subacute stroke patients.

이동형 서비스 로봇의 위치인식 기능은 성능평가시 중요한 평가척도의 하나로써 이용된다. 서비스 로봇이 다양한 작업을 수행하기 위해 여러 장소를 이동하게 되므로, 얼마나 정확하고 빠르게 위치인식을 하는 것이 로봇의 종합적인 성능에 큰 영향을 미치기 때문이다. 이를 위해 로봇은 영상이나 다양한 거리 센서를 활용하여 위치인식의 성능향상을 도모하고 있다. 그럼에도 불구하고 현재 영상기반의 위치인식 성능평가 방법과 관련한 표준이 없으며, 개별적인 성능평가만 시행되고 있다. 이에 우리는 이 논문을 통하여 전(前)방향 영상기반의 위치인식 알고리즘 성능평가 방법과 평가척도를 제안한다. 제안된 위치인식 알고리즘 성능평가 방법은 현재 지능형로봇 표준포럼의 표준으로 채택되었으며, 이를 통해 앞으로 영상기반 위치인식 알고리즘을 평가하고 개발하는데 기준 역할을 할 수 있을것으로 기대된다.

In this paper, we described evaluation software that can propose rating scale and evaluate automatically on SDR(Software-Defined Radio) transmitter system. To deduct suitable rating scale, we extracted requirements based on the operating environment, operating application and operating method because SDR operating software is subordinative to the hardware. And we implementation evaluation software to automatically quality evaluation using rating scale draw from the requirements. The implemented evaluation software has automatically evaluation functions using script, can update the evaluation factor and show visual evaluation result. The implemented evaluation software is used to useful the high quality SDR operating software development.

Estimation of software project cost, effort and duration in the early stage of software development cycle is a difficult and key problem in software engineering. Most of models estimate the development effort using the function point that is measured from the requirement specification. This paper presents optimal team size and duration prediction based on function point in order to provide information that can be used as a guide in selecting the most Practical and productive team size for a software development project. We introduce to productive metrics and cost for decision criteria of ideal team size and duration. The experimental is based on the analysis of 300 development and enhancement software project data. These data sets are divide in two subgroups. One is a development project; the other is a maintenance project. As a result of evaluation by productivity and cost measured criteria in two subgroups, we come to the conclusion that the most successful projects has small teams and minimum duration. Also, I proposed that predictive model for team sire and duration according to function point size based on experimental results. The presented models gives a criteria for necessary team site and duration according to the software size.

Objective : This study aimed to develop a Comprehensive Oro-Facial Function Scale (COFFS) that can evaluate oro-facial function in patients with dysphagia. Methods : To verify the item composition and reliability of the COFFS, preliminary items were collected by selecting and analyzing four previous studies, and the Content Validity Ratio (CVR) was derived through a second survey of experts. Cronbach's 𝛼 was calculated for the internal validity of the evaluation items, and the test-retest reliability and inter-rater reliability were calculated using the internal classification coefficients (ICC). Results : The content validity ratio of all items was 0.67; in the case of Cronbach's 𝛼 value for each domain, 0.849 for communication domain, -0.224 for the oro-facial structure and shape, 0.831 for the ability to perform orofacial movements, and 0.946 for mastication and swallowing function. The test-retest reliability was 0.974 and the inter-rater reliability was 0.937, showing high reliability. Conclusion : In this study, the evaluation tool of COFFS was finally selected from 34 items in four areas and developed on a 3-5 point scale according to the evaluation items. In future studies, additional research is needed to prove its validity through correlation with other evaluation tools that measure oro-facial function.
