Engineering structures usually suffer from cracks. The crack geometry has an influence on the structural mechanical properties and subsequent crack propagations. However, as an extensively utilized method in fracture analysis, the extended finite element method provided by Abaqus fails to output the specific location and dimensions of fractures. In this study, a technique to capture the crack geometry is proposed. The technique is based on the invariant level set method (I-LSM), which can avoid updating the level set function during crack development. The solution is achieved by an open-source plug-in programmed by Python. Three examples were performed to verify the effectiveness and robustness of the program. The result shows that the developed program can accurately output the crack geometry in both the 2D and 3D models. The open-source plug-in codes are included as supplementary material.

소프트웨어 개발비용의 대부분이 생명주기 중에서도 특히 테스트 공정에 소비된다. 일반적으로 디버깅을 위해 자주 사용되는 기법으로서 백트랙(backtrack) 기법과 프로 그램 슬라이스 기법이 있으나 디버거에 대한 풍부한 경험이 요구되거나 대규모 프로그램 에 대해서는 적용하기 곤란하다. 본 논문에서는 표준적으로 사용되고 있는 설계문서의 정보를 이용하고 벡트랙기법과 프로그램 슬라이스 기법을 조합시킨 새로운 오류 위치의 결정 방법을 제안하였다. 디버깅 기법을 제안하기 위해 몇 가지 기본개념과 대상으로 하는 오류, 표준적인 설계문서 및 제안하는 오류 위치의 결정방법에 대해서 기술하였다. 그리고 오류가 포함한 프로그램의 예를 이용하여 제안한 방법의 절차를 설명하였으며 끝으로 제안방법과 일반 슬라이스 기법을 비교.분석하였다.

Purpose: This study was aimed to evaluate the effects of a maternal education program based on the temperament theory on the temperamental goodness-of-fit between mother and child. Method: The research method was a nonequivalent, control group, non-synchronized design and the experimental period was from May 10, 2004 to July 24, 2004. The subjects were mothers who had children 3-4 years old who registered in eight kindergartens or infant schools in M city. Among the total 94 subjects, 47 were allocated as an experimental group and 47 were a control group. Using the SPSS/WIN 10.0 program, the data was analyzed by a Chi-square test, and t-test. Result: 1. After treatment with a maternal education program based on the temperament theory, the experimental group significantly decreased in scores for perceived children's behavior problems in comparison to the control group(t=-4.01, p<.001). 2. After treatment with a maternal education program based on the temperament theory, the experimental group did not significantly decrease in scores for parenting stress in comparison to the control group(t=-.85, p=.40). 3. After treatment with a maternal education program based on the temperament theory, the experimental group did not significantly decrease in scores for rejective parenting behaviors in comparison to the control group(t=-1.32, p=.19). Conclusion: A maternal education program based on the temperament theory is a useful intervention to decrease perceived children's behavior problems.

The purpose of this study is to apply to the phenomenological self-evaluation method in the social welfare agency. It means that the phenomenological self-evaluation method accepts "the reality" which occurs in the social welfare setting, and functions for the social worker to play dual role of practitioner-evaluator. This paper examines two dimensions of social work evaluation theory and practice. Firstly, this study is to investigate a trend of evaluation in social work setting, and seeks theoretical aspect of phenomenological self-evaluation method, with emphasis on the strength and limit of the positivism evaluation methods. Although qualitative evaluation was suggested to make an alternative to the positivism by qualitative researchers, they did not suggest the specific methods and roles of the practitioner-evaluator. In this study, two directions of the phenomenological self-evaluation method are suggested to overcome the limitations. which are "environment-relation self-evaluation" and "program-oriented self-evaluation". Secondly, the result of phenomenological self-evaluation studies for the social welfare community center program and organization in kangnam district from June, 1994 (Program-oriented self-evaluation) to march, 2000 (Environment-relation self-evaluation) are presented. the phenomenological self-evaluation study showed the expected outcome such as; reflective self-training, making a practice knowledge, enhancing service quality, and reinforcing the identity of social welfare profession.
