As a method to lead a change in mathematics education, recently reformation of assessment appears as a concept of process-focused assessment. Process-focused assessment is the concept that 2015 revised mathematics curriculum aims for, which is promoted also in policy. This research suggested a significance of process-focused assessment that has not been determined in conceptualization and the practical model. For this, this research investigated the content of the assessment on 2015 revised mathematics curriculum, and explored process-focused assessment based on the recent education assessment theory and research. Also, we suggested a model of practical plan by investigating the condition to perform the process-focused assessment. This research could take a basic role to practice process-focused assessment and investigate the concrete plan in the mathematics class field.

Runtime Intrusion Prevention Evaluator (RIPE), published in 2011, is a benchmark suite for evaluating mitigation techniques against 850 attack patterns using only buffer overflow. Since RIPE is built as a single process, defense and attack routines cannot help sharing process states and address space layouts when RIPE is tested. As a result, attack routines can access the memory space for defense routines without restriction. We separate RIPE into two independent processes of defense and attacks so that mitigations based on confidentiality such as address space layout randomization are properly evaluated. In addition, we add an execution mode to test robustness against brute force attacks. Finally, we extend RIPE by adding 38 attack forms to perform format string attacks and virtual table (vtable) hijacking attacks. The revised RIPE contributes to the diversification of attack patterns and precise evaluation of the effectiveness of mitigations.

This study was conducted to provide basic data for prioritization of family support services by examining the importance and performance of family support for parents of children with special education. To achieve the purpose of the study, a questionnaire survey was conducted with 220 parents of children from special education nationwide. As a result of the study, the importance of all 29 family support service items was rated high, but the performance level was low, and statistically significant differences were found. In addition, as a result of analysis of importance and performance, family support services related to physical and physical well-being and disability-related support were evaluated as high-priority, low-practice services, and it was a task that should be presented as a priority in family support services. On the other hand, it was found that family support services in the areas of family interaction support or emotional well-being were considered to be services that should be avoided due to their low importance but high performance. Based on the results of these studies, the direction for the operation of family support services for children with special education needs to be suggested in the future.

소프트웨어 스트리밍[1]은 프로그램 설치 및 실행을 위하여 서버로부터 데이터 전송이 진행중인 동안에도 PC, PDA, 휴대용 개인 컴퓨터, 휴대 전화 등과 같은 데스크 탑 또는 이동 연산장치 상에서 미설치 소프트웨어의 실행이 즉각적으로 이루어지도록 하는 기능이다. 즉, 소프트웨어 스트리밍 기술을 사용하면 사용자가 다운로드, 압축해제, 인스톨과 시스템 재구성이라는 일련의 과정이 완료될 때까지 기다릴 필요 없이 최소한의 다운로드 후에 해당 소프트웨어가 곧바로 실행될 수 있도록 해준다. 응용프로그램을 실행하는데 필요한 첫번째 실행 블록이 메모리에 적재되고 기본적인 환경설정을 마치자마자 나머지 블록들이 다운로드되고 설치되기도 전에 실행될 수 있기 때문에 스트리밍 시스템은 응용 프로그램의 실행준비 시간을 대폭 줄일 수 있게 해준다. 게다가, 응용프로그램 실행시 실제로 사용되지 않는 대부분의 블록들은 서버로부터 다운로드 받지 않아도 된다. 그 결과, 메모리와 대역폭 같은 리소스의 활용이 절약된다. 이러한 스트리밍 시스템을 사용하면 사용자는 다양한 공개 또는 상업용 응용프로그램을 광범위하게 지원하는 사용자 투명성을 가진 가상 소프트웨어 컴퓨팅 환경을 만들 수 있다. 본 논문에서는 리눅스 환경에서 설계 구현된 Software On-Demand(SOD) 스트리밍 시스템을 소개하고, SOD 스트리밍 시스템의 성능측정을 위한 소프트웨어를 설계한다.

This study was conducted to investigate the apraxia affects activitys of daily living. 38 patients with stroke were participated and conducted to both Birminham Cognitive Screen(BCoS) apraxia test and K-MBI for ADL. Using a cutoff score of BCoS apraxia test, all patient was determine whether with apraxia or not and were distinguished by various types of apraxia. They were compared to the level of ADL using ANOVA. Apraxia patients 18, patients without apraxia is 20. The difference of ADL between the two groups was not. However, the result of classifying patients with apraxia subtypes, it showed a significant difference in grooming, eating, toileting, step, bowel control, and bladder control(F=4.431~9.193, p<0.05). As apraxia is cause of a negative effect on ADL, expert in the area to manage stroke patients should have to share information about whether apraxia is or not and make policy and treatment program considering the potential problem in ADL.

This paper presents adaptive execution techniques that determine whether parallelized loops are executed in parallel or sequentially in order to maximize performance. The adaptation and performance estimation algorithms are implemented in a compiler preprocessor. The preprocessor inserts code that automatically determines at compile-time or at run-time the way the parallelized loops are executed. Using a set of standard numerical applications written in Fortran77 and running them with our techniques on a distributed shared memory multiprocessor machine (SGI Origin2000), we obtain the performance of our techniques, on average, 26%, 20%, 16%, and 10% faster than the original parallel program on 32, 16, 8, and 4 processors, respectively. One of the applications runs even more than twice faster than its original parallel version on 32 processors.

Traditionally research in Service Oriented Architecture(SOA) security has focused primarily on exploiting standards and solutions separately. There exists no unified methodology for SOA security to manage risks at the enterprise level. It needs to analyze preliminarily security threats and to manage enterprise risks by identifying vulnerabilities of SOA. In this paper, we propose a metric-based vulnerability assessment method using dynamic properties of services in SOA. The method is to assess vulnerability at the architecture level as well as the service level by measuring run-time dependency between services. The run-time dependency between services is an important characteristic to understand which services are affected by a vulnerable service. All services which directly or indirectly depend on the vulnerable service are exposed to the risk. Thus run-time dependency is a good indicator of vulnerability of SOA.
