목초액과 bentazone+cyhlofop-butyl(BCB) 혼용처리에 따른 피 방제효과를 조사하기 위하여 목초액을 0.1%, 0.2% 농도를 사용하여 BCB와 목초액 혼용처리, BCB를 시용한 후 목초액을 처리하는 두 가지 방법을 사용하였다. 온도처리는 21/25℃, 25/20℃ 및 29/25℃의 3조건에서 수행하였다. 지상부 건물중 및 방제가에 있어 목초액과 BCB 50%를 혼용처리 하였을 때 가장 효과적이었으며 온도는 주야 25/20℃에서 방제가가 75%, 72%로 76%인 BCB 100% 처리와 비슷한 효과를 나타내었다. 모든 온도 조건하에서 목초액과 BCB 50% 혼용처리 시 엽록소 함량이 현저히 감소하였고, 주야 온도 29/25℃일 때 50+0.1% WVmix, 50+0.2% WVmix 처리시 각각 71%와 79%의 감소를 보여 가장 효과적이었다. 단백질 함량에서 온도 처리간에는 결과가 다르게 나타났으며, 목초액과 BCB 50% 혼용처리는 일관되게 낮은 단백질 함량 보여주었고 주야 25/20℃에서 BCB 50% 처리와 유의적인 차이를 나타내었다. 리놀렌산은 대조구와 비교하여 BCB 100% 처리와 50+0.1% WVmix 처리에서 각각 25%, 15%의 가장 큰 감소를 보였다. The synergistic effect of wood vinegar with ‘Chongilpum’ (bentazone+cyhalofop- butyl, BCB) on barnyard grass (Echinochloa crus-galli var. crus-galli) was investigated. Herbicide treatments were : BCB recommended rate (100% BCB : 100 dilution ratio applied at 100 L solution 10a-1), and half-recommended application rate (50% BCB : 100 dilution ratio applied at 50 L solution 10a-1), 50% BCB+0.1% WV (0.1% WV : 1 mL WV L water-1), 50% BCB+0.2% WV(0.2% WV : 2 mL WV L water), 0.1% WV, 0.2% WV, and untreated control. The 50% BCB plus WV treatments were applied as separate (wood vinegar BCB was applied 1 h after BCB) or mixed (BCB and WV were thoroughly mixed). Treatments were done under three temperature conditions (21/15, 25/20 and 29/25℃ day and night temperatures). Results revealed that mixing wood vinegar with 50% BCB at 25/20℃ obtained the highest efficacy (70%, comparable with 100% BCB) for aboveground biomass, efficacy and mortality values. Across temperature, mixing WV and 50% BCB likewise resulted in significant decrease on the chlorophyll content where 29/25℃ reached 71 and 79% reduction for 50+0.1% WVmix and 50+0.2% WVmix, respectively. Protein content showed great variations across temperatures nevertheless WV mixed with 50% BCB consistently showed lower protein contents across temperatures but were only significantly different with 50% BCB at 25/25℃. Linolenic acid showed the highest percentage reduction in terms of fatty acid, averaging at 25% on 100% BCB and 15% on 50+.01% WVmix.

The growth, yield and chemical properties of waxy corn $Sonjajang{\times}KNU-7$ and $Asan{\times}KNU-7$ planted in different dates and mulch types in a converted paddy field was investigated. Experiment was carried out in a randomized complete block design in a split split-plot arrangement with four replications. Planting dates (D) [May 16 (D1, early), June 1 (D2, middle), June 6 (D3, late)] represented main plots, plastic mulch (M) [(BM, black mulch; TM, transparent mulch)] for subplots while waxy corn crosses [$Sonjajang{\times}KNU-7$ (‘Sonja’) and $Asan{\times}KNU-7$ (‘Asan’)] for sub-subplots. Results showed that D had a significant effect on growth characters except emergence, ear quality except ear diameter, and yield whereas M showed significant effect on growth characters only. Superior growth and ear quality performance were recorded in D1 and BM. In terms of crosses, ‘Sonja’ had better growth performance than ‘Asan’ regardless of D and M, but performed better at D1 and BM. Highest yield was obtained in D1 for BM (2,131 kg $10a^{-1}$) and TM (1,655 kg $10a^{-1}$) but no significant difference in the yield across V was recorded. In terms of starch and sugar contents, a decreasing trend was observed from D1 to D3 regardless of M and V.

Effect of rice bran applied alone or in combination with chemical fertilizer on growth and edible quality of rice was investigated. The experiment consisted of 11 treatments: 3 levels of rice bran (RB) (500, 250 and 100 kg 10a-¹), 100 and 50% recommended fertilizer (RF) combined with above-mentioned 3 levels of RB, and 100 and 50% RF only. The rice brans were applied at 10 days before rice transplanting. Results showed that plant height 30 days after transplanting was significantly higher at 100% RF treatment than the RB treatments. However, plant height during heading stage was not significantly different between the 100% RF and the RB treatments. At higher RB treatments, ripened grain decreased, while panicle number and plant height increased. In the case of rice yield, 50% RF + RB treatments exhibited similar or slightly higher yield than 100% RF. These results suggested that the recommended fertilizer can be reduced by 50% in case of applying RB. In terms of nutritional quality, protein content on rice grain increased at higher RB treatment, while amylose content at 50% RF + RB treatments (17.3~17.8%) decreased compared to that of RF (17.9~18.1%). Results showed significant effects of RB application on rice growth and quality.

The growth and yield performance of 19 new com hybrids were evaluated. Results showed that all hybrids had a superior growth performance in the drained-paddy than in the upland field except for daeyul ${\times}$ cheongdo and hyoryeong ${\times}$ cheongdo in plant height, cheongdoyeop ${\times}$ wx-3 in tassel1ength, and cheongdo (black) ${\times}$ wx-3 in number of tassel branch. The same hybrids, except cheongdoyeop ${\times}$ wx-3, obtained lower ear quality in drained-paddy field compared to upland in terms of ear weight, and ear and grain setting length. The highest yield in the drained-paddy and upland fields was obtained in the hybrids ks5wx ${\times}$ ks6wx ${\times}$ cheongdo (1,633.3kg ${\cdot}$ $10a^{-1}$) and daeyul ${\times}$ wx-3 (1,516.7kg ${\cdot}$ $10a^{-1}$), respectively. Highest yield among the wx-3 crosses was obtained in daeyul which was 1,583.3kg ${\cdot}$ $10a^{-1}$ and 1,516.7kg ${\cdot}$ $10a^{-1}$ in drained-paddy and upland field, respectively. For the crosses of wx-8, highest yields were recorded in the cultivar bugye50 (1,466.7kg ${\cdot}$ $10a^{-1}$) and seokgu12 (1,384.6kg ${\cdot}$ $10a^{-1}$) for drained-paddy and upland field, respectively. In the case of cheongdo, highest yields were obtained in ks5wx ${\times}$ ks6wx (1,633.3kg ${\cdot}$ $10a^{-1}$) and seokgu14 (1,111.1kg ${\cdot}$ $10a^{-1}$) for drained-paddy and upland field, respectively. Result also showed that the drained-paddy soil had better physicochemical properties than the upland. The relatively high performance in terms of growth parameters and yield of com hybrids planted in the drained-paddy field is in agreement with the higher organic matter and micro-element content of drained-paddy field.

Primary Cytomegalovirus infection has been implicated and well-reported in immunocompromised hosts, particularly in patients with HIV, organ transplant recipients, and those with underlying malignancies. Among immunocompetent individuals, CMV infections were usually an incidental fi nding whenever IgM and IgG antibody determinations were included in the work-up of a patient presenting with fever and rash. More commonly we see IgG positivity which means that past CMV infections are usually mild enough to pass as ordinary viral infections. This is a case of acute CMV infection in an immunocompetent, young female who presented with prolonged fever. The following diagnostics were done as work-up for fever of unknown origin: blood, urine and stool culture; malarial smears; serologic tests for EBV, Toxoplasma and CMV; monospot and anti-nuclear antibody tests; CD4 and CD8 determinations. Serum CMV IgM positivity was the only signifi cant fi nding hence all subsequent diagnostics included CMV determinations. When CT scan of the chest and abdomen showed pulmonary infi ltrates and some abdominal lymphadenopathies, bronchoscopy was done and BAL examinations included Legionella IFAT; Pneumocystis jirovecii and fungal cultures; PCR for M. tuberculosis, PCP and CMV, in addition to the usual routine cultures. Laparoscopy was conducted to obtain a mesenteric lymph node which was sent for TB and CMV PCR. After failure to respond to empiric broad spectrum antibiotic therapy, the patient continued to have intermittent moderate to high-grade fever, headache and progressive shortness of breath. Subsequently, CMV PCR was positive in serum, lymph node and BAL samples, pointing to an uncommon condition of primary CMV infection in a healthy young individual. Because of persistence of symptoms for more than three weeks of hospital stay, she was started on Valganciclovir 1.8 gm/day and was discharged improved with completion of antiviral therapy.

The effect of rice bran (RB) applied alone or in combination with chemical fertilizer at different application rate on the phytochemical and antioxidant properties of rice was investigated. The treatments were 3 levels of RB namely: 200% RB (500 kg 10a-¹), 100% RB (250 kg 10a-¹), 50% RB (125 kg 10a-¹), Recommended fertilizer dose (RF: N-P₂O5-K₂O, 11-5.5-4.8 kg 10a-¹) combined with each RB, Half-recommended fertilizer dose (HRF: N-P₂O5-K₂O, 5.5-2.75-2.4 kg 10a-¹) combined with each RB, RF and HRF applied at 1, 5, 10 days before rice transplanting (DBT). The parameters investigated were antioxidant, phytosterol and fatty acid contents. Results showed that the antioxidant property and phytosterol contents were high at 10 DBT HRF plus RB, 5 DBT RF plus RB, and 1 DBT 100 and 200% RB. However, total polyphenols increased from 10 to 1 DBT. In the case of fatty acids, no general trend was observed between treatments at different application times. Linoleic acid was high at 10 DBT HRF plus RB while linolenic acid was not affected at different application times. Palmitoeic and oleic acids were not also affected at 5 and 10 DBT. Saturated fatty acids were not also affected by any treatment at different application times except for palmitic acid. Most parameters obtained higher values at 100 and 200% RB treatments in 1 DBT.

2003년에 이상적으로 많이 발생하여 벼에 심각한 피해를 가져온 혹명나방의 재배방법별, 엽록소 함량별 피해실태를 조사하여 피해에 따른 수량반응, 미질변화 등을 구명하고자 조사한 결과는 다음과 같다. 1. 혹명나방의 피해가 심할수록 벼의 등숙비율, 천립중의 감소와 복백립 등 미숙립의 증가에 따른 완전미 비율이 감소되어 완전미 수량이 피해가 심한 곳에서 36% 감소되었다. 2. 혹명나방의 피해가 심할수록 쌀의 외관상 품위가 떨어질 뿐만 아니라 단백질함량이 높아져 식미치는 감소되어 미질이 급격히 저하되었다. 3. 질소질 비료의 시용량이 증가할수록 혹명나방에 의한 피해는 증가하였으며, 특히 주남벼의 경우 질소량이 증가할수록 피해가 급증하였다. 4. 질소 시비량이 추천 시비량인 11 kg/10a를 초과시 피해엽율이 60% 이상으로 급증하였고, 60% 이상 피해를 입은 엽의 비율도 25%이상으로 늘어나 수량 감수 요인으로 작용하였다. The effect of rice bran (RB) applied alone or in combination with chemical fertilizer at different application rate on the phytochemical and antioxidant properties of rice was investigated. The treatments were 3 levels of RB namely: 200% RB (500 kg 10a-1 ), 100% RB (250 kg 10a-1 ), 50% RB (125 kg 10a-1 ), Recommended fertilizer dose (RF: N-P2O5K2O , 11-5.5-4.8 kg 10a-1 ) combined with each RB, Half-recommended fertilizer dose (HRF: N-P2O5K2O , 5.5-2.75-2.4 kg 10a-1 ) combined with each RB, RF and HRF applied at 1, 5, 10 days before rice transplanting (DBT). The parameters investigated were antioxidant, phytosterol and fatty acid contents. Results showed that the antioxidant property and phytosterol contents were high at 10 DBT HRF plus RB, 5 DBT RF plus RB, and 1 DBT 100 and 200% RB. However, total polyphenols increased from 10 to 1 DBT. In the case of fatty acids, no general trend was observed between treatments at different application times. Linoleic acid was high at 10 DBT HRF plus RB while linolenic acid was not affected at different application times. Palmitoeic and oleic acids were not also affected at 5 and 10 DBT. Saturated fatty acids were not also affected by any treatment at different application times except for palmitic acid.Most parameters obtained higher values at 100 and 200% RB treatments in 1 DBT.
