  • 밭 토양 특히 시설재배 토양의 질소시비량을 결정하기 위한 효율적 검정법으로 확인된 $NO_3-N$의 간이 검정법을 개발하기 위하여 Hanna Ion Specific meter를 이용한 비색법과 Test strip Reflectometer를 이용한 측정법을 선정하고, 실험실 분석법인 Specific Ion Meter에 의한 이온 전극법 및 Kjeldahl 증류법과 함께 비교 분석하였다. 평가방법은 토양중 $NO_3-N$ 함량이 $25mg\;kg^{-1}$$55mg\;kg^{-1}$인 두 토양에 대하여 각 분석방법을 7반복씩 수행하여 표준편차를 비교하였고, 두 토양에 $NO_3-N$ 표준용액을 첨가하여 $NO_3-N$ 함량이 각각 100, 150, 200, 250, $300mg\;kg^{-1}$인 표준농도 계열에 대하여 7반복으로 분석하여 회수율을 비교하였다. 또한 $NO_3-N$ 함량이 $10mg\;kg^{-1}$에서 $340mg\;kg^{-1}$으로 분포되는 시설재배 토양 20개 시료에 대하여 3반복씩 분석하여 $NO_3-N$ 농도에 따른 측정치의 신뢰도를 비교하였다. 분석방법에 따른 측정치의 신뢰도와 회수율은 이온 전극법이 가장 양호하였고 Kjeldahl 증류법, Test strip 간이법, Hanna 비색법의 순이었다. 간이 검정법에 따른 비교에서 Hanna 비색법은 낮은 농도와 높은 농도에서 큰 오차를 보였으나 Test strip 간이법은 실험실 정밀분석법인 이온 전극법 및 Kjeldahl 증류법과 버금가는 신뢰도와 95% 이상의 회수율을 보였다. 따라서 단순한 분석절차와 짧은 분석시간을 고려해 볼 때 Test strip 간이법은 질소 시비량의 결정을 위한 현장의 간이 검정법으로 활용 가능한 것으로 평가되었다.

  • A single trait linear mixed random regression test-day model was applied for the first time for analyzing the first lactation monthly test-day milk yield records in Karan Fries cattle. The test-day milk yield data was modeled using a random regression model (RRM) considering different order of Legendre polynomial for the additive genetic effect (4th order) and the permanent environmental effect (5th order). Data pertaining to 1,583 lactation records spread over a period of 30 years were recorded and analyzed in the study. The variance component, heritability and genetic correlations among test-day milk yields were estimated using RRM. RRM heritability estimates of test-day milk yield varied from 0.11 to 0.22 in different test-day records. The estimates of genetic correlations between different test-day milk yields ranged 0.01 (test-day 1 [TD-1] and TD-11) to 0.99 (TD-4 and TD-5). The magnitudes of genetic correlations between test-day milk yields decreased as the interval between test-days increased and adjacent test-day had higher correlations. Additive genetic and permanent environment variances were higher for test-day milk yields at both ends of lactation. The residual variance was observed to be lower than the permanent environment variance for all the test-day milk yields.

  • The following will describe a method of evaluating the SLAP lesion in the recurrent anterior dislocation of the shoulder. We have named it the biceps load test. The biceps load test is performed with the patient in the supine position and the arm to be examined is abducted 90/sup°/, and the forearm is in the supinated position. First, the anterior apprehension test is performed. When the patient become apprehensive, the patient is allowed active flexion of the elbow, while the examiner resists elbow flexion. If the apprehension is relieved or diminished, the test is negative. If aggravated or unchanged, the test is positive. A prospective study was performed, in which 75 patients who were diagnosed as having recurrent unilateral anterior instability of the shoulder underwent the biceps load test and arthroscopic examination. The biceps load test showed negative results in 64 of these patients, of which the superior labral-biceps complex was intact'in 63 cases and only I shoulder revealed a type n SLAP lesion. E]even patients with a positive test were confirmed to have type n SLAP lesions. A positive biceps load test represents an unstable SLAP lesion in a patient with recurrent anterior dislocation of the shoulder. The biceps load test is a reliable test for evaluating the SLAP lesion in the recurrent anterior dislocation of the shoulder(sensitivity: ,9] .7%, specificity: 100%, positive predictive value: 1.00 and negative predictive value: 0.98). Biceps contraction increases the torsional rigidity ?of the glenohumeral joint and long head of biceps tendan act as internal rotator of the shoulder in the abducted and externally rotated position. These stabilize the shoulder in abduction and external rotation position in the biceps load test.

  • Objectives : We investigated the effects of Hominis placenta Herbal acupuncture on rheumatoid arthritis. Methods : We investigated the Type II collagen-induced arthritis test, vascular permeability test, phenyl benzoquinone-induced writhing test, hot plate test, carbon clearance test, determination of prostaglandin $E_2$ content and cyclooxygenase-2 activity test. Results : Hominis placenta Herbal acupuncture suppressed Type II collagen-induced arthritis in DBA/1J mice and vascular permeability with 10.2% inhibition in ICR mice. We see the phenyl benzoquinone-induced writhing test and the hot plate test in the analgesic activity test. In the phenyl benzoquinone-induced writhing test, Hominis placenta Herbal acupuncture showed that it increased its analgesic effect more than the control(test?) by 85.5%. In the hot plate test, it was also shown that the analgesic effect increased more than the control(test) by 32.1%. In the carbon clearance test, the immuno-stimulatory effect showed more than the control(test) by 8.0%. The formation of prostaglandin $E_2$ was also reduced more than the control(test) by 10.1%. Finally, cyclooxygenase-2 activity was inhibitedwith 36.3%. Conclusions : Hominis placenta Herbal acupuncture may be useful for the treatment of rheumatoid arthritis after injection.

  • A survey of canine heartworm(Dirofilaria immitis) infections among dogs in Daefu area was performed from February 2000 to October 2002 using a microfilarial test and an antigen test(AGEN$^{TM}$ Canine heartworm). The infection rate of 220 dogs(96 males, 124 females) was 23.2%(51/22) by the microfilarial test, but was 23.6%(52/220) by the antigen test, revealing that 1 of 52 antigen-positive dogs were microfilaria-negative in the peripheral blood. All dogs that were microgilaria-positive were also antigen-positive. The infection rates of heartworm in dogs at the age of < 1, 1-3, 4-6, 7-11 and 12-15 years were 2.7%, 17.4%, 41.0%, 42.9% and 57.1%, respectively. Based on the fact that the antigen test is more accurate than the microfilaria test. The infection rates of heartworm in dogs by housing of indoor and outdoor were 6.9% and 46.4%, respectively. Based on the fact that outdoor housing is more infectious than indoor housing.

  • In this study, a horticultural therapy program was performed by employing the anger experienced by people during daily life activities in the emotion regulation strategy-based program to identify the influence of the horticultural program on anger control in the caregivers for patients with dementia. To measure this influence, two tools were used: a self-administered questionnaire survey, which is a subjective test, and an instrumental test, which can measure the physical index that detects the physical changes through anger. For the preliminary test, depression, stress, self-esteem, anxiety, and anger state-characteristic were tested using the self-administered questionnaire. For the follow-up test, the self-administered survey and the test using the physical index were performed in a manner similar to that of the preliminary test. The self-administered questionnaire comprised questions suitable to this study and considered the age, education level, and economic aspect of the subjects. The test results indicated that the experimental group subjected to the emotion regulation strategy-based horticultural therapy showed very significant reduction in depression and anger and significant reduction in stress, self-esteem, and anxiety. In the physical index test, the systolic and diastolic blood pressures were reduced, and the pulse rate and respiration rate reduced before and after the therapy, thus, proving the effectiveness of the therapy in anger control.

  • The objective of this study was to make comparison of the physical work capacities with different types and methods of tasks. To produce standard work loads, a bicycle ergometer and a treadmill were used for the purpose of two different types of tasks. Maximal oxygen uptake measurement tests are usually performen (1) continuously - with no rest between work load increments, or (2) discontinuously - with the subjects resting several minutes between work periods. Continuous test protocol with two different methods of work load increments, (1) ramp test- with 3 to 5 minutes of work period for each work load, and (2) incremental test - where exercise intensity was increased progressively in 2 minutes interval, were used. Predicted physicala work capacities (PWCs) were compared with the one by Kim(1990), and Lee(1995), and the NIOSH physiological criteria. For ergometer test, the PWC based on the ramp test was 89.65% of the one based on the incremental test. The PWC values were 2553.88 ml/min for the ramp test and 2848.82 ml/min for the incremental test. For treadmill test, the PWC based on the ramp test was 97.54% of the one based on the incremental test. The PWC values were 2786.89 ml/min for the ramp test and 2857.24 ml/min for the incremental test. The PWC obtained with a bicycle ergometer was 91.64% of the one obtained with a treadmill for the ramp test, and 99.71% for the incremental test.
