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.

Purpose: The Immunotech AFP is a widely used test in 14 hospitals(RIA QC establishments: 46) as a liver tumor marker. Normally, the test takes 45 minutes including complicated 2 step method. We evaluated the possibility of 1 step method and suitable test time. Materials and Methods: Samples of 31 patients in SNUBH were used as subject. We evaluated the sensitivity, intra and inter assay precision, recovery rate, linearity between 1 step and 2 step method (45 min. and 60 min.). Results: Both of 45 minutes and 60 minutes test showed 0.1 ng/mL sensitivity. In 45 minutes test, the intra assay coefficients of variation were 3.05%, 3.43%, 1.68%. Also, inter assay coefficients of variation were 3.91%, 2.38%, 0.82%. In 60 minutes test, the intra assay were 5.00%, 3.69%, 1.97%, inter assay were 3.14%, 3.71%, 1.85%.The correlation coefficient of each 2 step and 1 step (45 min.), 2 step and 1 step(60 min.), 1 step (45 min.) and 1 step (60 min.) were y=0.9293x+2.7356 ($R^{2}=0.9999$), y=0.9193x+4.1002 ($R^{2}=0.9993$), y=0.9894x+1.3805 ($R^{2}=0.9997$). Conclusion: Compared 1step method to 2 step method, both method showed very reasonable precision, recovery rate and correlation coefficient. Also, 1 step method(45 min.) of correlation coefficient ($R^2$) was 0.999. We suggest that 1 step method test can reduce the test time and is useful for AFP test.

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.

This paper describes the performance test procedures and results of NRSB-1M and NRSB-2M Not only aerodynamic performance test but also sound measurement test were performed for the small-scaled blades in the ground Total thrusts and torques of the rotor were measured using rotating balance for aerodynamic performance test. Sound pressure levels were measured using microphone in 1.64D distance for sound measurement test. Non-dimensionalized test data are compared and analyzed. Consequently, It was confirmed that NRSB-2 was better than NRSB-1.

In this research, 9 SAW welding specimens with 1 hour post-heat treatment (PH1) and 2 hours (PH2) were experimented to confirm the weldability and the joint performance of 60mm thickness HSA800 steel. SAW tests with PH1 & PH2, including weld impact test, bend test, hardness test, macroscopic test, and microscopic test, had a good test results. However, from the chemical composition test results, P composition was not satisfied with Korean Industrial Standards(KS). According to the weld-zone tensile tests, 2 hours post-heat SAW is recommended because the mechanical characteristics of SAW PH2 were better than those of SAW PH1.

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%.
