The purpose of this study was to assess repeatability and reliability of a new phoria test as compared to established phoria tests and to assess the possibility of mobile or online testing using the auto-flashed presentation. Near dissociated phoria was measured using the von Graefe method, the Howell card test, the modified Thorington test, and a new dichromatic card test (Red-Blue Phoria card test; RBP card test) on 109 subjects. The inter-examiner difference and test-retest difference were calculated. With the auto-flashed presentation of the RBP card test, near dissociated phoria was measured and the intraclass correlation coefficient and test-retest repeatability was assessed on 26 subjects. The variation in inter-examiner repeatability was the smallest for the modified Thorington test (+3.1/-2.6). The RBP card test was +3.0/-3.1, the Howell card test was +3.5/-2.7, and the von Graefe test was +6.2/-6.0. The variation in test-retest repeatability was the smallest for the RBP card test (+0.4/-1.4). The modified Thorington test was +1.3/-1.3, the Howell card test was +1.27/-1.45, and the von Graefe test was +1.59/-2.20. The ICC was 0.919 for the auto-flashed presentation of the RBP card test. The RBP card test is considered a highly repeatable method clinically and can be made a useful application for testing in mobile or online.

일본 연구에서는 열충격 시험을 통한 태양전지의 파괴모드에 따른 전기적 특성을 분석하였다. 시편은 Photovoltaic Module을 만들기 전 3 line Ribbon을 Tabbing한 단결정 Solar Cell을 제작하였다. 열충격 시험 Test 1의 온도조건은 저온 $-40^{\circ}C$, 고온 $85^{\circ}C$, Test 2는 저온 $-40^{\circ}C$, 고온 $120^{\circ}C$에서 Ramping Time을 포함하여 각각 15분씩, 총 30분을 1사이클로 500사이클을 각각의 조건으로 수행하였다. 열충격 시험 후 Test 1에서는 4.0%의 효율 감소율과 1.5%의 Fill Factor 감소율을 확인하였으며, Test 2에서는 24.5%의 효율 감소율과 11.8%의 Fill Factor 감소율을 확인하였다. EL(Electroluminescence)촬영 및 단면을 분석한 결과, Test 1과 Test 2 시편 모두 Cell 표면 및 내부에서의 Crack이 발견되었다. 하지만, Test 2의 시험이 Test 1보다 가혹한 온도조건의 시험으로 인해 Test 1에서 나타나지 않았던, Cell 파괴를 Test 2에서 확인하였다. 결국, Test 1에서 효율의 직접적인 감소 원인은 Cell 내부에서의 Crack이며, Test 2에서는 Cell 내부에서의 Crack 및 Cell 파괴로 인한 Cell 자체의 성능저하로 효율이 크게 감소한다는 것을 본 실험을 통하여 규명하였다.

The active-knee-extension (AKE) test has been used to measure hamstring muscle length. The traditional AKE test measures the popliteal angle to the point of resistance with a 90-degree flexion of the hip fixed by straps, while the stabilized AKE test measures the popliteal angle to the point of resistance with a 90-degree flexion of the hip stabilized using a pressure biofeedback unit providing lumbopelvic stabilization. The purpose of this study was to determine test-retest reliability of the traditional AKE test and stabilized AKE test. Twenty healthy adults participated in the study. The popliteal angles were measured with a digital inclinometer during each test. To assess the test-retest reliability between the 2 test sessions, intraclass correlation coefficients (ICCs) were calculated. The intrasubject coefficient of variation ($CV_{intra}$) was also calculated. To compare the traditional and stabilized AKE tests for changes in pressure, paired t-tests were applied. The results of this study were as follows: 1) ICCs(3,1) value for test-retest reliability was .96 in the traditional AKE test, and was .98 in the stabilized AKE test. 2) The maximal $CV_{intra}$ was 33.7% in the traditional AKE test and 15.7% in the stabilized AKE test. 3) Differences of $6.1{\pm}2.1$ mmHg in pressure were measured in the traditional AKE test, and differences of $1.2{\pm}1.0$ mmHg in pressure were measured in the stabilized AKE test. The results show the traditional and stabilized AKE test to be highly reliable, with test-retest reliability. However, the stabilized AKE test represented less variation and more stabilization than the traditional AKE test. Further study is needed to measure the inter-rater reliability of the stabilized AKE test for generalization and clinical application.

Sero-epidemiological study was carried out to observe the prevalence of brucellosis in 500 slaughtered as well as in 500 healthy animals in Peshawar district of N.W.F.P. All serum samples were subjected to four serological tests i.e. Standard Plate Test (SPT), Standard Tube Test (STT), Rivanol Test (RV) and 2, Mercapto-Ethanol Test (2, ME). The incidence of disease in 500 healthy animals tested by standard plate test, standard tube test, rivanol test and 2, Mercapto-ethanol test, was 2.8%, 1.8%, 1.6% and 1.2% respectively. While the incidence of brucellosis in 500 slaughter animals from Peshawar abattoir was 3.0%, 2.2%, 2.00% and 1.2% by standard plate test, standard tube test, rivanol test and 2, Mercapto-ethanol test The disease prevalence was higher in slaughtered animals as compared to healthy animals. The disease was more common in goats than sheep, also more prevalence in aged female than younger stocks. The efficacy of SPT was found more effective as compared to STT, RV, and 2, ME tests both in slaughtered as well as apparently healthy animals at Peshawar district. Standard Plate test detected 2.9%, Standard Tube test 2.0%, Rivanol test 1.8% and 2, Mercapto-ethanol test detected 1.2% positive cases in slaughtered as well as in healthy animals. So the Standard Plate Test was found to be more reliable, sensitive, and easy to performed.

Purpose: The purpose of this study was to examine the effects of aroma-inhalation on depression, sleep, mood, and smell in stroke patients and their caregivers. Method: This study employed one group pretest-posttest repeated design. Data were collected at three time points: baseline(pre-test), 10 days and 20 days after the intervention(Post-test1 and post-test2, respectively). The sample included a total of 23 subjects. Data were analyzed by SPSS 12.0 program using repeated measure ANOVA. Results: Depression was not statistically significant difference among pre-test, post-test1 and post-test2. Sleep was improved after intervention $37.61{\pm}7.41$(pre-test), $41.22{\pm}8.26$ (post-test1), $44.33{\pm}7.67$(post-test2) (F=8.182. p=.001) Mood was significantly improved after intervention: $16.95{\pm}4.89$(pre-test), $14.89{\pm}6.31$(post-test1), $12.11{\pm}5.04$(post-test2). Smell including smell perception, discomfort due to smell and relation between age and smell was significantly improved after intervention: $2.63{\pm}1.20$ (pre-test). $2.00{\pm}1.16$(post-test1), $1.63{\pm}.96$(post-test2) (F=6.176. p=.006) in smell perception, $2.50{\pm}1.10$ (pre-test). $1.81{\pm}.91$(post-test1), $1.19{\pm}.40$(post-test2) (F=12.26. p=.000) in discomfort due to smell and $3.53{\pm}1.18$(pre-test). $2.59{\pm}1.46$(post-test1), $2.53{\pm}1.33$(post-test2) (F=4.148, p=.025) in relation between age and smell. Conclusion: The results suggest that aroma-inhalation may have an effect on sleep, mood and smell and can be effective nursing intervention to increase the relaxation in stroke patients and their caregivers.

IEEE 1149.1 바운더리 스캔 칩들로 구성된 보드를 테스트하기 위한 패턴은 반드시 비트 스트림으로 구성되어야 한다. 그러나 이러한 비트 스트림을 생성하는 일은 IEEE 1149.1 표준에 대한 완벽한 지식이 필요하므로, 전문지식이 없는 SoC 설계자에게는 상당히 어려운 일이다. 본 논문에서는 Test Ready PCI 와 Test Ready USB로 정의한 PCI와 USB 장치를 통해 편리하게 테스트를 수행할 수 있게 도와주는 테스트 인터페이스 컨트롤러를 제안한다. 이 제어기는 TI사와 Lucent사에서 명령어 단위의 수준에서 테스트 비트 스트림을 생성하기위해 개발한 테스트 버스 컨트롤러를 기반으로 하여 테스트 전문 지식이 없는 설계자도 쉽게 테스트 패턴을 생성하여 테스트를 수행할 수 있는 장점이 있다.
