Charpy V-Notch test is commonly used to evaluate fracture toughness. However, since the region to be evaluated is limited to bulk material due to the specimen size required, individual evaluation of micro-structures on weldment is very difficult. In this study, ASP(Advanced Small Punch) test was carried out to evaluate material degradation and fracture toughness on the B.M, W.M and each micro-structures of HAZ for X20CrMoV121 and 2.25Cr1Mo steels with artificial aging time. In addition, to evaluate fracture toughness and material degradation of B.M and W.M of X20CrMoV121 steels with aging times, CVN (Charpy V-notch) test was performed. And then the correlation between ASP and CVN test on X20CrMoV121 steels was obtained. Furthermore, through this correlation, material degradation property of each micro-region of the HAZ in weldment, which was impossible to be evaluated by the CVN test, can be estimated and determined.

Species of scotochromogenic mycobacteria of Group II isolated from sputa of patients with pulmonary tuberculosis and tuberculosis-like diseases from 1979 to 1984 were identified by simple biochemical tests using. nitrate reduction, Tween-80 hydrolysis, arylsulfatase and urease test, and serotypes of the isolates belonging to M. scrofulaceum were differentiated by bacterial agglutination test. Of 39 strains. tested, 11(28.2%) proved to be M. scrofulaceum, 15(38.5%) M. flavescens and 13(33.3%) M. gordonae. But none of the isolates belonged to M. szulgai and M. xenopi known as major pathogens of mycobacteria of Group II. Of 11 strains of the isolates identified as M. scrofulaceum 3 strains(27.3%) each belonged to serotype 41 and 42, and 4 strains(36.4%) belonged to serotype 43, but one strain was not typable because of its inagglutinability by any one of the type specific sera. In addition, the sensitivity and specificity of rabbit immune sera against type strains of serotype 41, 42 and 43 of M. scrofulaceum were analysed by bacterial agglutination test. In the sensitivity of microplate test with 11 isolates of M. scrofulaceum, a comparative tandem test using 2 units and one unit of absorbed antisera against three serotypes appeared to be superior to a conventional microplate test using one unit of type specific antisera.

DA-5018, a non-narcotic analgesic agent, was examined for mutagenicity in the reverse mutation test on bacteria, chromosomal aberration test on cultured mammalian cells and micronucleus test on mice. The reverse mutation test was performed by a plate incorporation method with or without a metabolic activation system(S9 mix) using Salmonella typhimurium strain TA100, TA1535, TA98 and TA1537. DA-5018 did not significantly increase revertant colonies in any of the test strains under any conditions at concentrations ranging from 0.0049 to 1.25 mg/plate, compared with the vehicle control. In the chromosomal aberration test using cultured Chinese Hamster Lung(CHL) cells, DA-5018 did not increase the number of aberrant cells in the presence or absence of S9 mix at concentrations of 0.016 mM/plate to 0.25 mM/plate, compared with the vehicle control. In the micronucleus test, male ICR mice were given DA-5018 intraperitoneally at a dose level of 0.55, 1.10 and 2.20 mg/kg. The incidence of bone marrow micronucleated polychromatic erythrocytes in the DA-5018 treated mice was not significantly different from that of the vehicle control. These results indicate that DA-5018 does not have mutagenic potential under the present test conditions.

This study is to report the effectivenes of Meridian-Test (M-test) in 2 cases on shoulder diseases. The M-test was applied to one patient diagnosed with as impingement syndrome and one patient diagnosed with tear of supraspinatus tendon. The changes in numeral rating scale and range of motion were identified to assess the progress of the treatment. After three times treatments, In example 1, the pain decreased from 6 to 0.5 and the range of flexion and abduction increased from $150^{\circ}$ to $180^{\circ}$. In example 2, the pain decreased from 6.5 to 1, and the range of shoulder flexion increased from $120^{\circ}$ to $170^{\circ}$, while the range of abduction increased from $90^{\circ}$ to $170^{\circ}$. Based on the above results, it would be effective to apply M-test to treat shoulder diseases in these two cases.

Purpose : The conventional Whitaker test assesses the renal pelvic pressure response to a constant infusion rate of 10 mL/min in adult and 5 mL/min in children. We evaluated whether the infusion rate,5 mL/min is appropriate during Whitaker test in children. Materials and Methods : The study included 3 children with unilateral hydronephrosis, whose diuretic renography results were equivocal to define the presence of urinary obstruction. The kidneys were perfused at increasing flow rates from lmL/min. Results : There were intrapelvic pressure increases $26\;cmH_2O$ at 3 mL/min, $50\;cmH_2O$ at 2 mL/min and $80\;cmH_2O$ at 3 mL/min infusion rate, respectively. There was no need to increase the infusion rate over 4 mL/min to get a positive Whitaker test. Conclusion : Our experience with Whitaker test at variable low flow rates (1-5 mL/min) confirmed its usefulness in differentiating obstructive from nonobstructive uropathy. We recommend the increasing infusion rate from 1 mL/min during Whitaker test in children.

The for this study, turning circle tests and maneuvering indices were conducted to study and evaluate the maneuverabilities of the fishery training ship M.S. A-RA(G/T : 990tons). The results obtained were summarized as follows : 1. The advances of the starboard and port of the turning circle were measured based on the dumb card test method were 198m, 192m, the size of tactical diameters of them were 194m, 188m, respectively. 2. The advances at the starboard and port of the turning circles were measured according to the DGPS positioning obtained 196m, 194m, the size of tactical diameters of them were 194m, 190m, respectively. 3. The results were compared which came from the sizes of turning circle measured up with the dumb card test method during the trial test and from the size of turning circle measured according to the DGPS positioning. The advance of the turning circle measured at the time of the starboard turning according to the DGPS positioning was 1m longer than that of the trial test. And it was 21m shorter at the time of the port turning. 4. The rudder was steered at $35^{\circ}$ of rudder angle each starboard and port while the ship M.S. A-RA was advancing at full speed of 13 k't. The velocity of the ship was reduced to 7.8 k't at $180^{\circ}$ of turning angle and 6.0 k't at $360^{\circ}$ of turning angle and mean values of turning angular velocity of the port and starboard were $2.4^{\circ}$/sec and $2.3^{\circ}$/sec, respectively. 5. The Z test at each $10^{\circ}$, $20^{\circ}$, and $30^{\circ}$ of rudder angle was carried out to have the maneuvering indices K and T measured. K for the each rudder angle were 1.24, 1.45, and 1.65 while T for the each rudder angle were 0.33, 0.20, and 0.14. That is, K at the Z test at $30^{\circ}$ was greater than at the Z test of $10^{\circ}$ and $20^{\circ}$ while T at the $30^{\circ}$ Z test was less than at the Z test of $10^{\circ}$ and 20.

The purpose of this study is to propose the stiffness reduction factor for flat plate slabs under lateral loads. Current design code (e.g., ACI 318-05) requires considering the effects of cracks for calculating slab stiffness under lateral loads. This study collected the test results of 20 interior slab-column connections, from which stiffness reduction in each test was estimated with respect to the ratio of applied moment to cracking moment ($M_a/M_{cr}$). Based on collected data, this study proposed equations for calculating stiffness reduction with respect to $M_a/M_{cr}$. To verify the proposed equations, this study conducted the experimental test of interior slab-column connections under quasi-static cyclic loading. From the test, load-deformation curve is compared to that obtained from effective beam width method with the proposed equation for the stiffness reduction. It is shown that the effective beam width method with the proposed equation for stiffness reduction predicts accurately the test results.

Potassium phosphonate inhibited less mycelial growth of Phytophthora cactorum in vitro than metalaxyl-M. But the net protection rate in leaflet test and whole plant pot test was greater in potassium phosphonate than metalaxyl-M. P. ginseng appeared to have an induced resistance against P. cactorum with phosphonate around 50~100 ppm.

When the equipment which is related to safety or important to power production is installed in nuclear power plant units (NPPs), verification of equipment Electromagnetic Susceptibility (EMS) must be performed. The low-frequency radiated magnetic field susceptibility (RS101) test is one of the EMS tests specified in U.S NRC (Nuclear Regulatory Commission) Regulatory Guide (RG) 1.180 revision 1. The RS101 test verifies the ability of equipment installed in close proximity to sources of large radiated magnetic fields to withstand them. However, RG 1.180 revision 1 allows for an exemption of the low-frequency radiated magnetic susceptibility (RS101) test if the safety-related equipment will not be installed in areas with strong sources of magnetic fields. There is no specific exemption criterion in RG 1.180 revision 1. EPRI TR-102323 revision 4 specifically provides a guide that the low-frequency radiated magnetic field susceptibility (RS101) test can be conservatively exempted for equipment installed at least 1 m away from the sources of large magnetic fields (>300 A/m). But there is no exemption criterion for equipment installed within 1 m of the sources of smaller magnetic fields (<300 A/m). Since some types of equipment radiating magnetic flux are often installed near safety related equipment in an electrical equipment room (EER) and main control room (MCR), the RS101 test exemption criterion needs to be reasonably defined for the cases of installation within 1 m. There is also insufficient data regarding the strength of magnetic fields that can be used in NPPs. In order to ensure confidence in the RS101 test exemption criterion, we measured the strength of low-frequency radiated magnetic fields by distance. This study is expected to provide an insight into the RS101 test exemption criterion that meets the RG 1.180 revision 1. It also provides a margin analysis that can be used to mitigate the influence of low-frequency radiated magnetic field sources in NPPs.
