The spinal fusion in a lumbar region may influence biomechanically in the remained mobile segment to take over the lost motions Therefore the stress concentration on the adjacent segments may accelerate the degenerative changes, and then various late changes could occur. The aim of this study was to evaluate the late changes occuring in the adjacent segments to lumbar fusions. A retrospective review of radiographs and medical records was undertaken for 67 consecutive patients who had undergone various fusions in the lumbar region for various pathologic conditions. Included in this study were the patients who had performed active daily livings without any significant pain or disability after fusion and followed for a minimum of five years(up to 18 years with a mean of 8.3 years). The results of this study were as follows : The instability, disc narrowing, spinal stenosis, vertebral slipping, or isthmic defect were found in the adjacent segments to fusions in the patients who were followed longer, in L4-5 segment and above segment of fusion, and in the adjacent segments where a degenerative changes existed before surgery and where the angular motion increased considerably in a few years after fusion. The symptoms of these patients were responded well with conservative theraphy and no patient needed any surgical theraphy during these follow-up periods.

Objective : Banhahubak-tang is indicated for globus hystericus, marked by a subjective sensation as if something stuffed in the throat, chest distress, cough or vomiting, greasy whitish, taut and smooth pulse. In this study, the effects of Banhahubak-Tang extract (BHTe) were tested for anti-stress action. Methods : BHTe was extracted by pure water using electronic extractor and then fed to ICR male mice (20±2g) orally with the dose of 100㎎/㎏/day for five days. Mice were exposed to sociopsychological stress by restraining and seeing foot shock stressed mice for one hour for five days. Results : BHTe administered group showed a tendency of decreasing of serum corticosterone secretion when compared with control group, and BHTe administration also significantly up-regulated noradrenaline secretions in the dorsal cortex of brain. Lipid peroxidation of the brain tissues of mice were tested by measuring malondialdehyde, but BHTe showed no significant change. The elevated plus-maze test was designed to detect the effect of anxiolytic drugs, and BHTe administered group showed a significant increase of latency time. Conclusions : These results suggest that BHTe can effectively rid the psychological stress and it`s related diseases.

Using Real-Time Electron Microscopy To Explore the Effects of Transition-Metal Composition on the Local Thermal Stability in Charged Li_<i>x</i>Ni_<i>y</i>Mn_<i>z</i>Co_{1–<i>y</i>–<i>z</i>}O<sub>2</sub

Hwang, Sooyeon,Kim, Seung Min,Bak, Seong-Min,Kim, Se Young,Cho, Byung-Won,Chung, Kyung Yoon,Lee, Jeong Yong,Stach, Eric A.,Chang, Wonyoung American Chemical Society 2015 Chemistry of materials Vol.27 No.11

<P>In this work, we use in situ transmission electron microscopy (TEM) to investigate the thermal decomposition that occurs at the surface of charged LixNiyMnzCo1-y-zO2 (NMC) cathode materials of different composition (with y, z = 0.8, 0.1, and 0.6, 0.2, and 0.4,and 0.3), after they have been charged to their practical upper limit voltage (4.3 V). By heating these materials inside the TEM, we are able to directly characterize near surface changes in both their electronic structure (using electron energy loss spectroscopy) and crystal structure and morphology (using electron diffraction and bright-field imaging). The most Ni-rich material (y, z = 0.8, 0.1) is found to be thermally unstable at significantly lower temperatures than the other compositionsthis is manifested by changes in both the electronic structure and the onset of phase transitions at temperatures as low as 100 degrees C. Electron energy loss spectroscopy indicates that (i) the thermally induced reduction of Ni ions drives these changes, and (ii) this is exacerbated by the presence of an additional redox reaction that occurs at 4.2 V in the y, z = 0.8, 0.1 material. Exploration of individual particles shows that there are substantial variations in the onset temperatures and overall extent of these changes. Of the compositions studied, the composition of y, z = 0.6, 0.2 has the optimal combination of high energy density and reasonable thermal stability. The observations herein demonstrate that real-time electron microscopy provide direct insight into the changes that occur in cathode materials with temperature, allowing optimization of different alloy concentrations to maximize overall performance.</P>

'Umar 'Abu Ri­shah is one of the most famous lebanese poets in arabic love poetry "Gazal". He wrote not a few of love poetry Gazal in his life and tried to modernity of Gazal not only in the theme but also in the form. But he was not noticed by the students of arabic modern poetry including of Gazal. This article is a short attempt to figure out how 'Umar 'Abu Ri­shah described arabic women in his love poetry and what is modernity. The interesting phenomenon in modern arabic love poetry is the extent to which the poet is able to enjoy his beloved. This poetry concerns the body in an outspoken manner. However 'Umar's poetry concentrates upon representation lebanese women's mental states and inner life instead of description of her bodies. Besides his poetry characterized by its independent thematic unit apart from the Nasi­b. This is the most distinguished modernity in 'Umar's Gazal.

and Korean narrative works at the outset of modern time, noting that the enlightening narrative works both Egyptian and Korean literatures -particulary during that period- show several points of resemblance more than points of difference. It has been clear through this paper that each of "Takhlis al-Ibris fi Talkhis Baris" and "Seo Yo Kyun Mun" are considered the first two enlightening books in each of the Egyptian and Korean literature. By comparing the texts of the two books, I have found points of resemblance and points of difference in the method of presenting the subjects and thoughts. But the points of resemblance were far more than the points of difference until they were sometimes identical as if one of the writers used to copy from the other. This see The aim of this paper is to comparative between the enlightening Egyptian ms natural because each of them used to copy from the same civilization.

Otitis media with effusion (OME) is one of the most common disease in children but its pathogenesis is not clear. In particular the role of allergy has revealed conflicting support with widely varing opinions as to its importance. Within recent years, striking biochemical and immunochemical analytic techniques have opened a new approach the study of otitis media with effusion. So we focused on distributions of IgE in adenoid tissue and serum IgE levels. Authors compared the serum IgE and the distribution of IgE in adenoid tissue between the 20 patients underwent tonsillectomy, adenoidectomy and ventilating tube insertion and control group of 11 patients underwent tonsillectomy and adenoidectomy. The results were as follows; 1. In the distribution of IgE in adenoid tissue, there was a significant increase in the group of patients with OME compared to the control group (P<0.01). 2. In the analysis of serum IgE levels, the levels of IgE in the OME patients an control group were higher than normal level, although the level of IgE in the OME patients were less than that of control group, there was no significance P>0.05).

Five items among neurobehavioral core test battery of World Health Organization, including Santa Ana dexterity, pursuit aiming, digit symbol, simple reaction time, and Benton visual retention, were administered to the workers occupationally non-exposed to neurotoxic agents by operational guide for the WHO neurobehavioral core test battery. Subjects were volunteers from the industrial workers(117) and clerks(40). Detailed occupational history such as exposed agents including noise or vibration, educational level, residence, smoking and drinking habit were recorded. Most of the neurobehavioral tests were correlated with age and educational level. Smoking was correlated with pursuit aiming and digit symbol. Vibration affected pursuit aiming. Job type(industrial workers vs. clerks) and noise exposure did not affected among tested items. Multiple regression analysis was done for establishing predict equation to estimate normal ranges of the tests for male workers. Age was shown to be main independent variable affected for all tests except wrong dot of pursuit aiming. Educational level was also shown to affected most of the tests except Santa ana dexterity and wrong dot of pursuit aiming. Alcohol consumption affected Santa Ana dexterity, non-preferred hand, and smoking affected only wrong dot of pursuit aiming after multiple regression analysis.
