도메인 시험기법은 모든 데이터를 숫자로 간주하고 프로그램들이 숫자들을 처리하는 수학적 함수로 모델링하여, 프로그램내의 잘못된 조건문 사용을 발견하고자 하는 시험기법이다. 이 시험기법은 프로그램의 입력공간은 잘못된 조건문에 의해 잘못 분할되고 이러한 입력공간 분할 에러공간을 분할하는 경계 부근을 집중적으로 시험함으로써 발견할 수 있다는 아이디어를 기본으로 한다. 본 고에서는 도메인 시험기법의 중심개념인 조건문 해석과 입력공간 분할을 소개하고 구조적 단위시험 방법론으로서의 도메인 시험기법의 유용성을 고찰한다.

The design theory and implementation of a word processor system with more efficient processing of Korean and English text are studied. A screen editing method is implemented which is more flexible to handle the texts. Convinient control of the keyboards, cursors moving, texts editing, line marking and block operations are considered. The codes to avoid the complexity and inefficiency which are caused by difference of the code length between the Korean and English characters are reconstructed. File management systems and algorithms for executing the control commands are also studied. As a result, a successful word processor system is designed and implemental which performs a complete screen editing system. The performance of the system includes flexible cursor movement, margin setting, block operations of insertion, deletion and copying any sizes of the line and blocks; and also, the printout routines for size variation of the characters are worked out.

To recycle Ti alloy scraps and enhance the functionality of the recycled scraps, we manufactured low-oxygen contented Ti-Mo-Si powders using two types of ternary Ti alloy ingots which were prepared by vacuum arc melting of Ti-Mo scrap with different amounts of Si. The weight ratio of Ti-Mo scrap was Ti:Mo=9:1 and Si contents in two alloy ingots were 1 and 2 wt%. The alloy powders were prepared by the hydrogenation-dehydrogenation process and the oxygen atoms were removed by the deoxidation in solid state method. We confirmed that the deoxidation process effectively reduced the oxygen content of Ti-Mo-Si alloy powder from 3,350 ppm to 1,700 ppm. In addition, we confirmed that the high-temperature oxidation resistance was increased by adding Si to Ti-Mo alloys. Thermal gravimetric analysis showed that the weight gain of powders by the oxidation was reduced from 8.85% for Ti-Mo to 7.5% for Ti-Mo-Si at 1,500 °C.
