  • IEEE 1149.1 test architecture was proposed to support the test of elements within the boards. It is a large serial shift register that uses the TDI pin as an input and the TDO pin as an output. Even though it performs the board level test perfectly, there is a problems of running system level test when the boards are equipped to the system. To test real time operation signal on test pin, output speed of serial shift register chain must be above double clock speed of shift register. In this paper, we designed a runtime test architecture and a runtime test procedure under running system environments to capture runtime signal at system clock rate. The suggested runtime test architecture are simulated by Altera Max+Plus 10.0. through the runtime test procedure. The simulation results show that operations of the suggested runtime test architecture are very accurate.

  • In order to test the board with IEEE 1149.1 boundary scan design, the test sequence must be applied as the bit stream However it is very tedious job to generate the test bit sequence since it requires the complete hlowledge about the 1149.1. This fuper introduces a convenient PCI/USB interface controller, named as Test-Ready PCI (TRPCI) ard Test-Ready USB (TRUSB). Test Bus Controller has been developed by TI and Lucent aiming to generate the test bit stream as an instruction level, thus even the novice test engineer can easily generate the test sequence.

  • The huge test data volume, test time and power consumption are major problems in system-on-a-chip testing. To tackle those problems, we propose a new test data compression technique. Initially, don't-cares in a pre-computed test cube set are assigned to reduce the test power consumption, and then, the fully specified low-power test data is transformed to improve compression efficiency by neighboring bit-wise exclusive-or (NB-XOR) scheme. Finally, the transformed test set is compressed to reduce both the test equipment storage requirements and test application time.

In Sensory organization test, there were no significant differences in static eguibrium score in both groups(p<.05). 2. In Sensory organization test, there were significant differences in dynamic eguibrium score in both groups(p<.05). 3. In Motor control test, there were significant differences in both groups(p<.05). 4. In exercise group, there were no significant differences in static Sensory organization test(p<.05). 5. In exercise group, there were significant differences in dynamic Sensory organization test(p<.05). 6. In exercise group, there were significant differences in Motor control test(p<.05). 7. In control group, there were no significant differences in static Sensory organization test(p<.05). 8. In control group, there were no significant differences in dynamic Sensory organization test(p<.05). 9. In control group, there were no significant differences in Motor control test(p<.05).

  • Software testing is an activity to find defects included in software through creating test cases from the software system specification. In order to perform software testing effectively, it is required to prepare the full test plan, to create well-defined test cases, and to execute test monitoring activities systematically. Most existing researches for the test approaches focus on automating the activities from the test cases generation to the test execution. Contrary to those approaches, we study automatic approaches for test monitoring activities. For this, we identify the research issues that should be solved to automate test monitoring activities. Next, with those solutions, we suggest the construction method for an automatic framework for test monitoring.

  • Combustion test on two kinds of Indonesian sub-bituminous coals of single and blended with bituminous coal imported for power generation was carried out by using the test furnace at KEPRI. The main items of combustion test were temperature profiles of the inside furnace, the yield of unburned carbon, environmental pollution emissions, slagging/fouling tendency, and the comparison of heat loss of furnace. The test results showed that low sulfur and ash content characterized by the Indonesian coals were advantageous to environmental aspect, but high tendency of heat loss and slagging/fouling were disadvantageous to boiler operation. From the results, the necessity of proper coal blending to compensate these weak points was recommended.

  • Developed and conducted a performance test of the Water mist system that is satisfied with the requirement of a fire test requiring Class 3 Engine Mock-up exceeding net volume $3,000m^3$ as per IMO's MSC/Circ. 668 Appendix B(Test method for fire testing equivalent water-based fire-extinguishing systems for machinery spaces of category A and cargo pump rooms).Even though fuel atomizing was continued for 15 sec. after stopping of the system according to the test method relating to the atomizing fire type, no fire was reignited. This result shows the excellence of the system. There was no damage to the contents of the system after the test.

  • Hydrodynamic performance test of a turbopump for a liquid rocket engine is carried out. The turbopump is composed of an oxidizer pump, a fuel pump and a turbine, and the two pumps are driven by the turbine. In the test, water is used for the pumps as working media and air is used for the turbine. Performance parameters of pumps and a turbine are drawn, and a power balance between the pumps and the turbine are calculated. The calculation shows a good power balance, which implies that the pump component tests, the turbine component test and the assembly test are reliably performed. At the starting period of the test, pressure rise-flow rate curve of a pump gradually approaches the ideal curve which could be obtained by very slow starting.
