Purpose: To investigate complication rates and results of cataract surgery in a monocular patient compared to normal binocular cataract patients. Methods: We retrospectively analyzed 84 eyes of 84 patients that had undergone phacoemulsification, intraocular lens implantation and were followed up for 6 months or more. The fellow eye condition was classified into two different groups: Group A (experimental group) and Group B (control group). The best corrected visual acuity (BCVA) before and after surgery, operation time, nucleus sclerosis, and complication rate between the two groups were compared. Results: Both groups showed a significant level of visual improvement after 6 months (p < 0.01, 0.01). There was no significant difference in sex, age, preoperative lens opacity, pre- and postoperative visual acuity, spherical equivalent, astigmatism, and rate of complications (posterior capsule rupture [n = 1], uveitis [n = 1] vs. posterior capsule rupture [n = 3], intraocular lens capture [n = 1]. Conclusions: The present study showed no difference in surgical results between Groups A and B. The results demonstrated that cataract surgery in a monocular patient resulted in favorable visual improvement.

Purpose: To report a case of suprasellar arachnoid cyst with compressive optic neuropathy. Case summary: A 50-year-old man presented with decreased visual acuity in the right eye of 6 months duration. Best corrected visual acuity was 0.2 in the right eye, 1.0 in the left eye, and the intraocular pressure was 13 mm Hg in the right eye, and 18 mm Hg in the left eye. Fundus examination showed pale optic disc in the right eye and retinal nerve fiber layer defects in both eyes. Visual field examination revealed a central visual field of 10° in the right eye and an inferior visual field defect in the left eye. The brain magnetic resonance image (MRI) showed a suprasellar arachnoid cyst that compressing the optic nerve and chiasm. Conclusions: The author experienced arachnoid cyst accompanied by optic disc atrophy and visual field defect in a patient diagnosed and treated for glaucoma. In cases of non-specific clinical features that differ from typical glaucomatous presentations, the utilization of brain MRI appears to be helpful in diagnosis and treatment.

분산염료 분자구조에 따른 PU-함침 폴리에스터의 염색성

박종호,김성동,Park, Jong-Ho,Kim, Sung-Dong 한국섬유공학회 2008 한국섬유공학회지 Vol.45 No.3

Disperse dyes having different molecular structures were prepared and their dyeing properties on PU, PET and PU-coated PET were studied. A disperse dye with common structure showed faster absorption rate into PU for its high affinity to PU at low temperature and this resulted in faster dyeing rate on PU-coated PET than on PET. On the other hand, a disperse dye having bulky structure was adsorbed into both PU-coated PET and PET at similar rate and it showed little affinity to PU in the whole dyeing temperature range. The amounts of disperse dyes eliminated from substrates by reduction clearing and washing fastness test were also measured. It was found that the disperse dye with bulky structure slipped out of PU in reduction clearing and washing fastness test in smaller quantity than the disperse dye with common structure. This phenomenon was corresponding well with the result of washing fastness test.

테레프탈산으로부터 합성한 알칼리 수용성 분산염료의 염색성과 견뢰도에 관한 연구

Dyeing and fastness properties of alkali-clearable disperse dyes of diester type, which were synthesized using diazo components derived from terephthalic acid, have been studied. They had good build-up properties and showed high exhaustion on regular polyester fiber. Washing and abrasion fastnesses of dyed polyester fabrics were excellent due to the solubility of the dyes in alkaline solution. Increase in molecular weight by introducing bulky sub-stituents to the dye improved sublimation fastness, while the addition of cyano group improved light fastness as expected. Fine denier polyester fabric dyed with the new disperse dye also exhibited excellent washing fastness. The newly synthesized dye barely stained cotton fiber, and gave good washing fastness of polyester/cotton blended fabric dyed by a one-bath dyeing method.

Insecticidal activity of 20 plant species against adults of Myzus persicae, female adults of Tetranychus urticae, and $2^{nd}\;or\;3^{rd}$ instar larvae of Plutella xylostella was evaluated in this study. Thirteen plant extracts showed over 80% acaricidal activity to T. urticae at the concentration of 1 %, while Capsicum annuum (hot-pepper seed), Inula helenium, and Acorus calamus revealed 82.8-86.2% acaricidal activities at 0.5%. Insecticidal activities of the plant extracts to M. persicae and P. xylostella were relatively low compare to the mite. Among the plant extracts, C. anuum and Brassica juncea revealed 48.6% and 42.9% respectively insecticidal activities to the aphid at the concentration of 0.5%. Extracts of C. anuum and Jeffersonia dubia provided 55% and 50% insecticidal activity against P. xylostella at 1%. And, the highest antifeeding activity of the insect was observed in the J. dubia extract as 79.4%. Results indicated that some plant extracts including hot pepper seed could be used as potential botanical pesticides for organic farming. 유기재배 농가에서 해충방제용으로 이용하거나 해충에 살충력이 보고된 식물추출물 20종을 점박이응애, 복숭아혹진딧물 및 배추좀나방에 대해 살비, 살충 효과를 검정하였다. 이들 중 13종의 식물추출물은 1% 농도에서 점박이응애에 대해 80%이상의 높은 살비력을 보였다. 그러나, 0.2% 농도에서는 모두 50% 미만의 살충율을 보였고, 0.5% 농도에서는 창포, 목향 및 고추씨 추출물이 각각 82.8%, 82.8%, 86.2%의 높은 살비력을 나타내었다. 복숭아혹진딧물에 대해서는 고추씨와 겨자 추출물이 0.5% 농도에서 48.6%와 42.9%로 가장 높은 살충력을 보였다. 배추좀나방의 경우 1% 농도에서 황련과 고추씨 추출물이 50%와 55%의 살충력을 보였고 나머지 추출물의 살충효과는 50% 미만으로 낮았다. 하지만 여러 식물추출물이 배추좀나방 유충의 섭식을 저해하는 효과를 보였으며 황련 추출물을 처리한 경우 유충의 섭식저해율이 79.4%로 가장 높았다. 본 실험을 통해 천연살충제로서 고추씨와 같이 사용이 용이한 식물체추출물이 유기농업에 이용 가능성이 있음을 확인할 수 있었다.

토마토재배에 사용하는 농약과 친환경농자재가 곤충 병원성 곰팡이 Beauveria bassiana의 병원성에 미치는 영향

박종호,홍성준,한은정,심창기,이민호,김민정,김정준,김용기,Park, Jong-Ho,Hong, Sung-Jun,Han, Eun-Jung,Shim, Chang-Ki,Lee, Minho,Kim, Min-Jeong,Kim, JeongJun,Kim, Yong-Ki 한국응용곤충학회 2012 한국응용곤충학회지 Vol.51 No.4

This study was conducted to observe the influence of chemical pesticides and environmentally friendly agricultural materials (EFAMs) used in tomato cultivation on the pathogenicity of the entomopathogenic fungus, Beauveria bassiana. B. bassiana mycelium didn't grow on PDA media containing 13 fungicides including chlorothalonil and colonies were not formed on PDA media containing 12 fungicides. B. bassiana mycelium grew and colonies were formed on all PDA media containing insecticides and EFAMs, but mycelial growth and colony formation on most PDA media were significantly inhibited compared to the control. The insecticidal activity of B. bassiana against Trialeurodes vaporariorum was decreased when fungicides (polyoxin B, mandipropamid) and EFAMs containing sulfur were added, but insecticides (pyridaben, dinotefuran) and EFAMs originated from plant extracts did not have any influence on the insecticidal activity of B. bassiana. The pathogenicity of a mixture of B. bassiana and polyoxin B against T. vaporariorum was lower than that of B. bassiana alone under greenhouse conditions. 토마토 재배에 사용되는 농자재를 이용하여 곤충 병원성 곰팡이인 Beauveria bassiana의 병원성에 끼치는 영향을 조사하였다. Chlorothalonil 등 13종의 살균제 첨가 배지에서는 B. bassiana 균사가 전혀 생장하지 못하였고 chlorothalonil 등 12종의 살균제 첨가 배지에서 균총이 형성되지 않았다. 살충제와 친환경자재를 첨가한 모든 배지에서 균사가 생장하고 포자가 형성되었지만 대부분 배지에서 무처리와 비교했을 때 유의차를 보였다. 온실가루이에 대한 살충력은 B. bassiana 단독처리일 때보다 화학살균제(polyoxin B, mandipropamid)와 친환경농자재(sulfur) 혼합시 떨어졌으며 화학살충제(pyridaben, dinotefuran)와 식물추출물 유래 친환경농자재(pyrethrum) 혼합시에는 유의차가 없었으며 온실에서 살균제인 polyoxin B의 혼합으로 온실가루이에 대한 B. bassiana의 감염력이 떨어지는 것을 확인하였다.
