A new forensic saliva test method using $SALIgAE^{(R)}$ was evaluated in this study. The sensitivity and specificity of $SALIgAE^{(R)}$ were examined and compared to those of other saliva test methods such as agarose gel diffusion method and $Phadebas^{(R)}$ test sheet method. $SALIgAE^{(R)}$ showed high sensitivity and specificity to human saliva in addition to quickness. Moreover modified $SALIgAE^{(R)}$ method was cheap and easy to use in crime scene and DNA laboratory. $SALIgAE^{(R)}$ was very stable at room temperature and had no effect on STR typing.

Point of care testing (POCT) is could be easily and economically performed and was widely used. In particular, the test items using immune chromatographic method has been conveniently used. But when an error occurs, we should reaffirmed the test results, but we could not reaffirm because the test line is disappeared as the time pass, and the test results are different between laboratory workers. Therefore, we developed multi-strip reader which can store images for the test results and can interpretate the test results automatically. Then we evaluated newly developed multi-strip reader for urine pregnancy test, the test results of the multi-strip reader was 100% matched with the previously results. Our newly developed multi-strip reader was convenient and economic, and will be widely used in many laboratories.

현장방염처리 물품의 방염성능평가시 실내 인테리어 공사가 끝난 후 시험 시료를 채취하여 연소시험을 실시하게 되어있다. 그러나 이러한 절차로 인해 검사 소요시간이 길어지고 여러 민원이 발생하여 이를 대처할 시험 방법이 필요하다. 따라서 연소시험 대신 도막두께 측정 시험 방법을 도입하여 방염성능평가에 따른 문제점들을 해결하고자 한다. 도막두께 측정 시험의 경우 도막두께 측정용 라벨을 방염도료를 칠해야 하는 합판이나 목재 위에 붙이고 도료 작업이 끝나고 나면 관할 소방서에 이 라벨을 떼어서 제출하여 기준 도막 두께와 비교 측정하였을 때 기준 도막두께보다 두꺼우면 방염성능을 인정해주고 만약 기준 도막두께보다 얇게 칠해지면 현장 검사 또는 시료 채취 후 연소시험을 병행하여 검사함으로서 안전하고, 책임 있는 방염성능 시공을 할 수 있도록 관리 감독할 수 있을 것이다.

생산현장 업무에서는 측정검사업무의 비중이 크다. 측정검사의 업무는 품질향상을 위한 활동이며 또한 고부가가치의 제품을 위해서도 중요하다. 고품질 고정밀도는 철저한 측정검사를 통하여 이루어진다. 제품의 치수를 정확히 측정하여 정밀도 있는 부품을 제작하고 불량부품이나 파손된 부품을 검사하여 제거함으로써 제품의 성은과 품질이 우수하게 인정된다. 이러한 측정검사작업의 정밀도향상, 생산성 향상을 위해서는 자동화가 필요하다. 측정검사의 자동화 (CAT : Computer Aided Testing)에는 영상처리를 이용하는 시각검사의 자동화가 중요한 분야이다. 영상처리를 이용한 시각검사의 대상은 결함검사, 두께검사, 형상칫수 검사, 물체의 위치, 방향, 종류의 파악 등이 있다.

This study is a research for analysis the states of flame resistant treatment and its system which important in fire prevention by ignition delay of early stage of fire. Some problems arose in the flame resistant treatment site were analysed through the meeting with fire officer and businessman related with flame resistant treatment, and visiting the flame resistant treatment places. From the meeting, visiting and reviewing the code system we find the following problems. First one is a problem of excessive competition with many company in small market of flame resistant treatment and to reduce the cost, the businessman who have no professional technic do not work along the specification. Second one is the inspection system which do not inspect on site but inspect by sampling the flame resistant treated materials submitted by businessman. And there are some problems arose about the reliability and consistency of flame resistant performance of the sample and the treated site. To solve the above problems, we suggest some countermeasure.
