The results of the investigation of literature were summerized as follows ; 1. Information of voice, the pharynx, the larynx, the epiglottis, the uvula and the hyoid bone were concerned. 2. In disorders of voice and speech, Lung channel, Stomach channel, Spleen channel, Heart channel, Liver channel, Kidney channel, Im channel (任脈), and Chung channel (衝脈) were concerned. 3. The disorders of voice and speech were showed as follows ; aphonia, ashasia, seong-shi (?嘶), seom-eo(?語) kwang-eo (狂語), jeong-seong (鄭?), dok-eo (獨語) and chak-eo (錯語). 4. The cause of Aphonia and Aphasia were freauently as follows ; abnormal rising of Liver energy (肝邪暴逆), excessive heart fire (心火太過), deficiency of heart-blood (心血太虛), apoplexy of heart spleen (心脾俱中風), consumption of lung fluid caused by heat evil (肺津被灼), deficiency of lung energy (肺氣虛寒) and dificiency of kidney energy (腎虛). 5. The cause of seom-eo, kwang-eo, Jeong-seong were as follows ; the heart of stomach (胃中熱), the heat evil attach the blood chamber (血人血室) and the consumption of healthy energy (精氣奪). 6. In disorders of voice and speech, flaceid tong with aphasia (舌?) and aphasia due to throat disease (喉?) were divided.

Pectobacterium carotovorum subsp. carotovorum (formerly Erwinia carotovora subsp. carotovora) is a plant pathogen that causes soft rot and stem rot diseases in several crops, including Chinese cabbage, potato, and tomato. To control this bacterium, we isolated a bacteriophage, PP1, with lytic activity against P. carotovorum subsp. carotovorum. Transmission electron microscopy revealed that the PP1 phage belongs to the Podoviridae family of the order Caudovirales, which exhibit icosahedral heads and short non-contractile tails. PP1 phage showed high specificity for P. carotovorum subsp. carotovorum, and several bacteria belonging to different species and phyla were resistant to PP1. This phage showed rapid and strong lytic activity against its host bacteria in liquid medium and was stable over a broad range of pH values. Disease caused by P. carotovorum subsp. carotovorum was significantly reduced by PP1 treatment. Overall, PP1 bacteriophage effectively controls P. carotovorum subsp. carotovorum.

A 52-year-old man was referred to our clinic for an 11.3 mm nodule in the left lower lobe that was discovered on a chest computed tomography (CT) scan. Eleven small nodules were subsequently found in both lungs. Initially, we performed a transthoracic needle aspiration using CT scan guidance. The pathologic report showed a few clusters of atypical cells that were suspicious for malignancy. The positron emission tomography images revealed multiple lung nodules scattered throughout both lungs. The largest nodule (11.3 mm) in the left lower lobe did not have any discernible fludeoxyglucose uptake. For pathologic confirmation, we consulted a thoracic surgeon to perform the video assisted thoracoscopic surgery. The final diagnosis was minute pulmonary meningothelial-like nodules (MPMNs). MPMNs are benign in nature, and only a few cases require treatment. However, when clinicians are suspicious of potential malignancy, a pathological correlation is essential, even if the final diagnosis is MPMNs.
Optimization of solvent condition for highly luminescent Y2O3:Eu3+ nanophosphor
Sung-Jei Hong,Min-Gi Kwak,Jeong-In Han 한국물리학회 2006 Current Applied Physics Vol.6 No.1l
In this paper, effect of synthetic conditions on the particle size, crystal structure, and the photoluminescence properties of the Y2O3:Eu3+ nanophosphor was investigated. Solvent and dispersing agent were determined as the synthetic parameters. The nanophosphor synthesized from methanol solvent showed the smaller particle size and the wider specific surface area of 4 nm and 80 m2/g, respectively. The XRD analysis indicates that the crystal structure of the Y2O3:Eu3+ nanophosphor is mainly cubic crystal with orientation of (222), (440), (400), and small peak of (511) indicating monoclinic crystal. The Y2O3:Eu3+ nanophosphor synthesized by using methanol solvent and 0.1 wt.% hydroxypropyl cellulose (HPC) as a dispersing agent showed higher degree of crystallization of 10.5 of I(2 2 2)/ I(5 1 1) ratio than that without HPC. Also, the photoluminescence properties of the nanophosphor showed red color that excitation and emission wavelengths of the nanophosphor were 250 and 611 nm, respectively. Using the 250 nm UV source, the highly intensive photoluminescence peak could be achieved at 611 nm under the synthetic condition of methanol solvent adding 0.1 wt.% HPC.
