Objective : The aim of this study is to establish the value of hand elevation test as a reproducible provocative test for the diagnosis of carpal tunnel syndrome (CTS). Methods : We had a prospective study of 45 hands of 38 patients diagnosed with CTS between April 2005 and February 2009. The diagnosis of CTS was based on the American Academy of Neurology clinical diagnostic criteria. Experimental and control group patients underwent Tinel's test, Phalen's test, carpal compression test and hand elevation test as provocative tests for CTS. Results : We used chi-square analysis to compare Tinel's test and Phalen's test, carpal compression test with hand elevation test. The sensitivity and specificity of the hand elevation test is 86.7% and 88.9% each. Tinel's test had 82.2% sensitivity and 88.9% specificity. Phalen's test had 84.4% sensitivity and 86.7% specificity. Carpal compression test had 84.4% sensitivity 82.2% specificity. Comparisons of sensitivity and specificity between hand elevation test and Tinel's test, Phalen's test, and carpal compression test had no statistically significant differences. To compare the diagnostic accuracies of four tests, the area under the non-parametric receiver operating character curve was applied. Conclusion : The hand elevation test has higher sensitivity and specificity than Tinel's test, Phalen's test, and carpal compression test. Chi-square statistical analysis confirms the hand elevation test is not ineffective campared with Tinel's test, Phalen's test, and carpal compression test.

In order to establish a sensitive and specific diagnostic method for detection of antibody to Salmonella pullorum, a enzyme-linked immunosorbent assay(ELISA) was designed and standardized. The diagnostic efficacy of the established ELISA was compared with that of the serum plate agglutination test and immunodiffusion test for pullorum disease. 1. The chicken hyperimmune sera to Salmonella pullorum, S gallinarum, S typhimurium and S typhi were shown the cross reaction to S pullorum antigen by serum plate agglutination test. 2. When compared the cross reaction titer of microplate agglutination test for chickens hyperimmune sera, it was found that the titer were 64 in S pullorum, 32 in S gallinarum, 4 in S typhimurium and 8 in S typhi, respectively. 3. When compared the specificity of various antigen(HA, EA, PA and SA) by the immunodiffusion test, the most suitable antigen was phenol-treated bactrium. 4. The optimal concentration of S pullorum antigen for ELISA was 1 : 160 dilution of bacterium. 5. The efficacy of the ELISA for detection of S pullorum antibody was compared with serum Plate agglutination test and immunodiffusion test in chickens infected with S pullorum. The antibody was first detected at 6 days after infection using three tests examined. The antibody was alldetected at 9 days by ELISA, at 12 days by serumplate agglutination test, at 15 days by immunodiffusion test.

In this paper, we consider the entropy-based goodness of fit test (Vasicek's test) for a composite hypothesis. The test measures the discrepancy between the nonparametric entropy estimate and the parametric entropy estimate obtained from an assumed parametric family of distributions. It is shown that the proposed test is asymptotically normal under regularity conditions, but is affected by parameter estimates. As a remedy, a bootstrap version of Vasicek's test is proposed. Simulation results are provided for illustration.

Objectives : The purpose of this study is to find out the relation between Orthopedic Test of sacroiliac joint and two Sacrum Malposition Tests. Methods : We investigated 56 cases of patients who complained of unilateral sacroiliac joint pain and were diagnosed as sacrum malposition. We used Gaenslen's Test, Sacroiliac Resisted Abduction Test and Patric's Test as Orthopedic Test for pain area, while used Thompson's Sacrum Test and Greenman's 4 Point Test for diagnosis of sacrum malposition. Results : P-value was 0.511 between Thompson's Sacrum Test and Greenman's 4 Point Test within negative Orthopedic Test, and was 0.523 within positive Orthopedic Test(p>0.05) Conclusions : The results suggested that the Thompson's Sacrum Test was not statistically correlation with Greenman's 4 Point Test within negative Orthopedic Test, and was not correlated within positive Orthopedic Test.

Ely's test is commonly used to assess rectus femoris muscle flexibility. however, a reliability limit of this test was demonstrated by a previous study. In this study, we present an alternative method using an application for a digital horizontal level in a smartphone (DHLS) to complement the reliability limit of Ely's test. The aim of this study was to examine the reliability of Ely's test using DHLS on the pelvis, compared to using visual observation (VO) of pelvic and hip motions. Nineteen patients with lumbar extension-rotation syndrome were recruited for this study. An examiner examined the rectus femoris flexibility (both pass/fail and goniometer scoring) through Ely's test using both DHLS and VO. A retest session was completed two hours later for within-day reliability and seven days later for between-day intra-rater test-retest reliability. Results showed higher Kappa values for pass/fail scoring and higher intraclass correlation coefficient values for goniometer scoring in Ely's test using DHLS, compared to using VO. Measurement error and Bland and Altman plots further demonstrated the degree of intra-rater variance during Ely's test using DHLS in a clinical setting, compared to using VO. These results demonstrated that Ely's test using DHLS showed acceptable reliability compared to using VO. Ely's test using DHLS could be widely used for measuring the rectus femoris muscle flexibility in patients with lumbar extension-rotation syndrome, although the inter-rater reliability needs to be established first.

소프트웨어 개발 과정에서 신뢰성 평가는 대단히 중요하다. 테스트 단계를 구분하지 않은 소프트웨어의 신뢰도 평가˙분석의 결과는 신뢰성이 결여될 수 있다. 따라서 본 논문에서는 이러한 문제점을 해결하기 위해 테스트 단계를 구분하여 신뢰성 평가에 관한 연구를 하였다. 이를 위해 단위 테스트(Unit Test), 통합 테스트(Integration Test), 확인 테스트(Validation Test), 시스템 테스트(System Test)에서 발견된 결함 데이터를 이용하여 소프트웨어 신뢰도 성장 모델(Software Reliability Growth Model : SRGM)인 지수형, 지연 S자형, 습숙 S자형 SRGM에 적용하였다. 그 결과 단위 테스트에서는 습숙 S자형, 통합 테스트에서는 지연 S자형, 확인테스트에서는 지연 S자형, 시스템 테스트에서는 지수형 SRGM이 가장 적합한 것임을 입증하였으며, 신뢰성 평가 척도인 파라미터 추정, 편차 자승합, 기대잔존 결함수 등에서 본 연구의 결과가 기존의 방법보다 우수함을 보였다.

In this study, S-wave velocity range is gauged in every field test method at the total 5 locations in the marine deposits in Incheon area. field test method is accomplished the SPT(Standard Penetration Test), CPT(Cone Penetration Test), SPS(Suspension PS Logger), SCPT (Seismic Cone Penetration Test) and so on. The S-wave velocity of SCPT in the downhole test method is measured lower than SPS logger at the N value > 15 range. But at the N value < 15 range, SPS logger and SCPT result is measured same. In this result, although the soil strength of the downhole test method increased, the rate of S-wave velocity is tend to be slowed. This result shows that the downhole test is difficult to apply at the place that the intensity of soil is more extreme and harder soil. And it shows that the existing Imai(1982) type that is mostly used within the country is not suitable for the marine deposits. Thus, the empirical formula that can show the range of S-wave velocity in each N value for domestic soil is needed.

제주지역 양식 넙치의 주요 세균성 질병의 일종인 연쇄구균증 원인균 Streptococcus iniae 및 Streptococcus parauberis에 대한 생물학적 특성을 시험하였다.온도별 성장 시험결과 S. parauberis 균주는 10℃ 배양조건에서 성장이 이루어졌으나 S. iniae 균주의 경우는 10℃에서는 성장이 확인되지 않았으며, 용혈성 시험결과에서는 S. iniae 균주의 경우에만 β용혈성을 나타내었다.생화학적특성 시험결과 acetoin production test (VP test), hippurate hydrolysis test (HIP test)에서는 S. parauberis 균주의 경우에만 양성반응을 보여 두 균주사이에 뚜렷한 차이를 보였다.또한 α-D-glucose, D-mannose, D-psicose, D-trehalose, pyruvatic acid methyl ester, glycerol은 두 균주 모두 기질로 이용하였으나 L-lactic acid는 S. iniae 균주만이 이용하였고, β-methyl-D-glucoside의 경우는 S. parauberis 균주만이 기질로 이용하는 것으로 나타났다.병원성 시험결과, S. iniae는 급성감염 형태를 보인 반면에 S. parauberis는 만성 감염형태를 보임으로써 차이를 나타내었다.
