The PBM ${BioSign}^{TM}$ Salmonella (PBMS) test kit based on an mmunochromatographic method was evaluated for the screening of Salmonella spp. in pure cultures, and 80, 15, and 10 artificially and naturally contaminated, and negative controlled food samples, respectively. The PBMS test involves presumptive qualitative procedures, detecting the presence of Salmonella spp. in foods within 26 h total testing period and allowing the user to release negative products 70 h earlier than the conventional methods. The PBMS test using Buffered Peptone Water and Rappaport-Vassiliadis broth was evaluated for 10 different food types for various Salmonella spp. It showed detection limits of 1 to 25 colony forming units (CFU)/25 g. No cross-reaction was observed, particularly to other gramnegative bacteria. These results indicate the PBMS test is a rapid and inexpensive procedure for the screening of Salmonella spp. present at low concentrations (1 to 25 CFU/25 g) in foods.

The radiopharmaceuticals are routinely injected to blood vessel for acquiring PET image. For this reason, It is imperative that they undergo strict quality control measures. Especially, Sterility test is more important than any other quality control procedures. According to the FDA guideline, It requires filter integrity test used in the processing of sterile solutions. Among several methods, we can decide to use bubble point test. We usually use vented GS-filters (Millipore co., USA) which are sterilizinggrade (0.22 um pore size) and are placed upper site on product vial. After the synthesis of $^{18}F$-FDG, solutions wet the membrane in filter and then go into the product vial. By all synthesis steps have finished, we can observe the presence of the bubbles in the product vial. Since we have started this study, we have never found any bubbles in the product vial. Because the maximum pressure intensity of the filter which has set by manufacturer is up to 5 bars, but helium gas pressure is up to 1 bar in our module system. So, we can make 5 bars pressure using helium gas bombe and increase pressure up to 5 bars step by step. However, it does not happen to anything in vial.

This study is intended to provide navigator with specific information necessary to assist in the avoidance of collision and in operation of ships to evaluate the manoeuvrability of own ship. The actual manoeuvering characteristics of ship can be adequately judged from the results of typical ship trials manoeuvres. Author carried out sea trials based full scale for turning test, zig-zag test, spiral tests and crash-stop test at actual sea going condition. The turning circle manoeuvres were performed on starboard and port sides with $35^{\circ}$ rudder angle at the service speed, and Zig-zag procedures were performed on both sides with $10^{\circ}$ and $20^{\circ}$ rudder angle respectively. Spiral tests were carried out on the both sides and crash stop test was also carried out. The results from tests could be compared directly with the standards of manoeuverability of IMO and consequently the manoeuvring qualities of the ship is fully satisfied with its.

TMN(Telecommunication Management Network) provides underlying structure to transfer, store and processing management information which are necessary for Telecommunication network and service management. The application of TMN is widely applicable to Analogue telecommunication network Public and private network switching system, Transmission system, Telecommunication related software and logical telecommunication network resource management and others. This paper consider TMN as one System Under Test(SW), and propose a new TMN test architecture, besides existing simulation based test method, which is able to test, on the basis of standardized testing procedure and testing method, directly with test system. There are several fields in protocol testing and one of them is protocol conformance testing which is defined in ISO/IEC 9646 series and it has twin document as ITU X.290 series. To apply this standardized procedure on TMN testing it is prerequisite to devise a new TMN testing architecture and set up testing procedures according to the new architecture.

KASI is developing the MIRIS (Multi-purpose IR Imaging System), as the main payload of Science and Technology Satellite-3 (STSAT-3). The Engineering Qualification Model (EQM) of the MIRIS has been recently fabricated, and Flight Model (FM) is now in final development stage. The system performance tests have been made mainly with EQM, and partly with FM in the laboratory, including opto-mechanics test, vibration test, thermal-vacuum test and passive cooling test down to 200K, using a thermal controlled vacuum chamber. Most of the system performance test results of the MIRIS are satisfied with the required specifications and its results were reflected in development of the FM with several revisions of the system design. In this paper, we present detailed system performance test procedures of the MIRIS and its results.

This paper introduces the performance test of the prototype vehicle, which will be in operation for Urban Maglev Program. While common trains with steel wheels use rotary induction motors for propulsion, maglev trains gain thrust force from linear induction motors maintaining the constant airgap with levitation electromagnets. Therefore, not only the behavior of the linear induction motor should be well understood, but also the way of propulsion that minimizes its effect on the levitation system should be took into account. Performance test procedures of maglev trains are proposed and carried out, and the characteristics of acceleration and deceleration are verified to agree with the design criteria. Tests are mainly performed on the linear section of the test line, and the driving characteristics on the section with a 6‰ incline are examined additionally. As a result, the performance of the prototype vehicle in the reverse operation can satisfy the requirement about the acceleration and deceleration, 4.0$m/s^2$. And, the design modifications of the commercial vehicle and the performance specifications required on the demonstration line are investigated.
