표절을 쉽게 알아내기 위해, 프로그램 유사성 검사기(CloneChecker)를 만들었다. CloneChecker는 프로그램을 요약해서, 유사성을 계산하고, 비슷한 그룹들로 묶어 낸다. CloneChecker는 두 프로그램의 모든 부 구문트리(abstract syntax sub-tree)들을 서로 비교하므로 구문의 사소한 변화에 민감하지 않으며, 그럼에도 해쉬 함수를 이용하여 빠르게 수행된다. CloneChecker는 실제 강의에서 사용되었으며, C, Java, Scheme, nML로 짜여진 프로그램들에 대해 동작한다.

Accurate blood typing tests are essential for safe blood transfusion. Recently many automated test equipments have been introduced to reduce errors and increase the efficiency of the test. However, those equipments being high in price, it is difficult to introduce automated test equipment for every hospital. In this study, we developed a reader for blood typing using column agglutination test. In the process, the results, read out by the image processing, are stored and reaffirmed. To evaluate the reader, 148 samples for ABO and RhD blood typing tests and 154 samples for unexpected antibody test were used. The positive and negative intensity of the reading and the reading of the reaction were 100% in agreement with the result of traditional manual method. If additional verification is completed, this reader can be efficiently and economically used in small-and medium-sized hospitals.

Deployment of an advanced on-line monitoring of the component integrity offers a prospect of improved performance, enhanced safety, and reduced overall cost for nuclear power plants. Ultrasonic guided waves have been known as one of the promising techniques that could be utilized for on-line monitoring. The present work is aimed at developing a new method for on-line monitoring of the pipes during the operation period of nuclear power plants. For this purpose, the steam generator (S/G) tube was selected as an object of tile experiment. Dispersion corves and the incident angles corresponding to the specific modes were calculated for the S/G tube. The modes of guided waves were identified by the time-frequency diagrams obtained by the short time Fourier transform. It was experimentally confirmed that there was no mode conversion when the ultrasonic guided waves passed over the curved region of the S/G tube. An optimum mode of guided wave for the S/G tube was suggested and verified by the experiment.

Various ECT techniques have been applied basically to assess the integrity of steam generator tithing in nuclear power plant. Among these techniques, the bobbin probe technique is applied generally to examine the volumetric flaws such as a crack-like defect and wear which is generally occurred on steam generator tubing, and additionally MRPC probe is used to examine closely tile top of tubesheet and bending regions due to the high possibility of cracking. Dent and bulge also may be formed on tube during installation process and operation of steam generator, but the dent and bulge indications greater than specific size criteria are recorded on examination report because these indications are not considered as flaw. These indications can be easily detected with bobbin probe and approximately sized with profile bobbin probe, but the size and shape can not be accurately verified. Accordingly, in this study, the $8{\times}1$ multi-array EC probe was designed to increase the measurement accuracy of the sectional profiling EC testing of tube. As a result, we would like to propose the application of $8{\times}1$ multi-array EC probe for the measurement of size and shape of profile change on steam generator tube in OPR-1000 nuclear power plant.

It is not easy to find out syntactic error in a spelling checker systems of Korean, because the spelling checker is generally to correct each phrase and it cannot check the errors of contextual ill-matched words. Spelling checker system tests errors based on a words. Disambiguation of lexical ambiguities is important in natural language processing. Its outputs is used in syntactic analysis. For accurate analysis of a sentence, syntactic analysis system must find out the ambiguity of morphemes in a word. In this paper, we suggest several rules to resolve the ambiguities of morphemes in a word. Using these methods, we can reduce many lexical ambiguities in Korean.

Ssooksulgis made with different levels of Mugworts were tested to investigate the texture characteristics by sensory evaluation and mechanical test in this study. As a result of the sensory evaluation for Ssooksulgis with the levels of 0%, 10%, 20%, 30% and 40% , the consistency, texture, moistness and flavor were increased according to the increase of the added Mugworts. In view of color and overall quality, 30% Ssooksulgis was preferable than those of other mixing levels. In the texturometer measurement for Ssooksulgis, hardness tend to decrease, while springiness and cohesiveness tend to increase according to the increase of the added Mugworts. As for Ssooksulgis, the consistency and moistness in sensory evaluation correlated significantly with the cohesiveness and correlated negatively with hardness, chewiness, gumminess in mechanical test (p<0.01).
