명령형 언어로 작성된 프로그램에 대한 정적 분석을 효과적으로 수행하는 방법을 제시한다. 흐름을 고려하면서 분석 할 때, 일부의 계산만이 분석 결과를 만들어내는 데 이바지한다. 주어진 입력 메모리로 어떤 명령문을 계산할 때 입력 메모리의 일부만 계산에 사용하고, 계산의 결과는 입력 메모리에서 일부만 변경된 값이기 때문이다. 또한, 변경된 값이 다시 계산에 사용되기까지 불필요한 값의 전달을 수반한다. 이 논문에서는 가벼운 전분석을 통해 불필요한 계산들을 미리 찾아내어 계산에서 제외하는 방법을 제시한다. 상용화된 요약해석 기반 분석기에 이 기법을 적용하고 10개의 오픈 소스 프로그램에서 실험한 결과 분석속도가 평균 65배 빨라졌다. 또한, 최근에 제안된 필요한 정보만 가지고 계산하기 기법을 적용한 결과에 비해서도 분석속도가 평균 16배 빨라졌다.

In this study, a meta-analysis was conducted to investigate the effect of community-based rehabilitation on patients with brain injury by ICF factor in previous studies and examine the application of recent community-based rehabilitation program. Total 15 articles that satisfied the selection criteria were divided by ICF factors to obtain the effect size. Homogeneity and publication bias were tested for those selected papers. As a result, the overall effect size of community-based rehabilitation was 0.22; the effect size by physical function and structure among the ICF factors came to be 0.21; and the effect size of activity and participation was 0.20, indicating a small effect size. The studies involved in a meta-analysis were considered as the absence of heterogeneity and publication bias, which indicates that the results of this study are subjectively reliable. These results well explained the level of change on ICF factors, especially physical function and structure, activity and participation, in other words, the intervention effect of community-based rehabilitation on patients with brain injury.

Despite the rapidly increased concern on the circularity of the program development activities in the social service agencies, there are only a few studies about the phenomena. This study is to describe the characteristics of program development in the process of adopting, developing, and disseminating the social programs and to figure out the factors influencing differences in the 3 activities in social service agencies. The researchers constructed an explanative model including each 12-13 independent variables with 3 consecutive dependent variables on the basis of reviewing the related literatures. A multiple regression analysis was applied to predict the features of the program development using 195 questionaries responded from social workers in community service centers. As the result of the descriptive analysis, the two noticeable features are found; (1) the agencies have very actively adopted outside programs, developed appropriate programs for the agency, and disseminated the programs into other agencies in the community. (2) there are some positive aspects of the factors in related to the process of the program development. The results of the regression analysis show that the three dependent variables of the adoption, development, and dissemination are very closely interconnected with each others, showing the evidence of the circularity in the agencies. In addition, the 5 independent variables at the value of p .01 are statistically related with the circularity of the three dependent activities. The implication of major findings were discussed in academic and practical perspectives in Korea, including future research works in the area.
