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.

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.

AFP검사에 있어서 본원은 Immunotech사의 시약을 사용하고 있고 방법은 2 step법(IRMA)이다. 본원 내원환자 31명의 샘플을 대상으로 다소 번거로운 2step법을 1step법으로 간소화 할 수 있는지 비교실험을 하였다. 본법, 변법1(1step 45분), 변법2(1step 60분)의 상관계수와 회귀식, 정밀도, 회수율, 민감도, Hook effect를 확인하였다. 저, 중, 고역가 검체의 측정내 정밀도는 변법1은 3.05%, 3.43%, 1.68% 변법2는 5.00%, 3.69%, 1.97% 측정간 정밀도 는 변법 1은 3.91%, 2.38%, 0.82 % 변법2는 3.14%, 3.71%,1.85% 였다. 분석적민감도는 0.1 IU/mL 였고 직선성은 우수하였다. 상관관계는 각각 y=0.9293x+2.7356 ($R^{2}=0.9999$), y=0.9193x+4.1002 ($R^{2}=0.9993$) 이었다. 2,000 IU/mL 미만에 서는 Hook effect가 나타나지 않았지만 고농도에서는 Hook effect가 나타났다. 이 비교실험을 종합해 보면 본법과 변법1, 변법2 모두 상관관계, 정밀도, 회수율, 민감도 등이 우수함을 알 수 있다. 하지만, 고농도에서 Hook effect가 나타나 완전히 대체해서 사용하기에는 문제가 있다고 사료 된다. 다만, 정상인이 거의 대부분인 건강검진검사에서는 유용하게 사용될 수 있을 것으로 판단된다.

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 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.

본 논문에서는 차세대 블레이드인 NRSB-lM과 NRSB-2M의 성능시험 절차 및 결과에 대해 기술하였다. 축소 블레이드 성능시험으로 공력 성능 시험과 소음 시험을 수행하였다. 공력 성능시험은 회전발란스를 이용하여 로터 추력 및 토오크를 측정하였고, 소음 측정시험은 마이크로폰을 이용하여 1.64D 위치에서 소음을 측정하였다. 측정된 성능 데이터는 무차원화하여 분석하였고, 두 블레이드 결과를 서로 비교하여 NRSB-2 블레이드가 더 좋은 블레이드 임을 확인하였다.

본 연구에서는 HSA800 60mm 강재의 SAW 용접성 및 이음성능을 확인하기 위해 후열처리 1시간과 2시간에 대한 SAW 공시체를 제작하여 9종의 시험을 실시하였다. 용접부 충격시험, 굽힘시험, 경도시험, 매크로조직시험, 마이크로조직시험 결과 SAW PH1 및 PH2는 양호한 용접부로 나타났으나, 화학성분시험 결과 P성분이 KS를 만족하지 못하였다. 용접부 평판 및 봉형 인장시험결과 SAW PH1에 비하여 PH2의 기계적 특성이 양호하게 나타났기 때문에 SAW의 경우 후열처리는 2시간을 권장한다.

LA test was carried out with commercial Toxo-MT kit (Eiken chemical co.). The results obtained were summerized as follows : 1. The cut-off titer of positive and negative reactions by Toxo-MT antigen used in this experiment was determined as the serum dilution of 1 ; 32. 2. positive rates of toxoplasma antibodies in 823 swine sera were 17.0%(140 cases) by LA test. 3. The toxoplasma antibody detection rates against 194 swine sera in breeding-pig farm, 273 swine sera in pig farm and 356 swine in abattoir were 46.9%(91 cases), 8.4%(23 cases) and 7.3% (26 cases) , respectively. 4. In LA test serum antibody titers in 823 test sera were shown as 51 cases (36.4%) in 1 : 32, 40(28.6%) in 1；64, 17(12.1%) in 1:128, 14(10.0%) in 1：256, 10(7.1%) in 1:512, 5(3.6%) in 1：1,024, and 3(2.1%) in 1 : 2,048. 5. Positive rates of toxoplasma antibodies in swine sera from each breeding-pig farm were 20.0∼61.9%.
