The authors analyzed 32 cases with lower cervical spine injuries according to their etiologies, the findings of cervical spine X-ray and computed tomography, initial neurological grading scales and time of operation. The results are summarized as follow : 1) Lower cervical spine injuries occurred in 32 of the 49 cervical spine injuried patients. 2) The important factors affecting on outcome were the initial neurological state(p=0.038) and the degree of spinal canal narrowing on cervical computed tomogram(p=0.046). 3) The degree of prevertebral soft tissue swelling and displacement of vertebral body on initial cervical spine X-ray did not significantly affect on outcome(p=0.052). 4) The most suitable operative time for lower cervical spine injuries was 10∼20 days after injuries and the mortality was 9.3%.

Background: Thus far, research studies on community-acquired pneumonia (CAP) have focused on its clinical severity. Recently, it has been determined that procalcitonin (PCT) level is correlated with severity of CAP. A retrospective study conducted at our hospital used risk predictability and PCT to determine whether or no PCT is useful in assessing the severity of CAP. Methods: This study covered 92 CAP cases that were admitted to the respiratory department at Changwon Fatima Hospital between July 1, 2008 and June 30, 2009. All enrolled subjects were measured for infection markers and risk predictability. Results: Based on hospital admission data, enrolled subjects had Pneumonia Severity Index (PSI) scores serving as risk predictors showed that both PCT and white blood cell (WBC) were statistically significant as infection markers (p=0.001, 0.037). Thus, this study used ROC curves in PSI for data analysis. As a result, it was determined that the area under curve (AUC) of PCT and WBC was 0.694 and 0.593 respectively, indicating that PCT has a higher test value for WBC, when PCT was higher than 0.745 ng/mL. In addition, it was found that PCT levels higher than 0.745 ng/mL had higher PSI scores than the group with PCT lower than 0.745 ng/mL (p=0.032). Conclusion: In order to predict risk of pneumonia cases admitted due to symptoms of CAP, it is important to consider PCT as well as PSI, and follow-up monitoring of PCT cases.

Construction Supervision System has been introduced in the domestic construction industry since 1962 At this time, Construction Supervision System has been earned out by architects And it has not been separated the public sector and the private one Especially, the government has put in operation the supervision systems of housing to improve the quality dud to prevent the fraudulent work in apartment construction projects from 1994 However, there are many problems of the supervision systems of housing in the view point of the practical operation, the scope of supervising, the assignment of supervisors, the ambiguous tasks of supervision in the housing construction projects Therefore, this paper suggests the Improved plan of the housing supervision system, the supervisor assignment institution, the detail services of supervision, and about the exceptional construction works in the housing supervision services.<br/>

<P><B>Abstract</B></P> <P>We report the preparation of solid-state facilitated olefin transport membranes based on a low-cost, one-pot, room-temperature synthesized graft copolymer, i.e., poly(ethylene-alt-maleic anhydride)-g-O-(2-aminopropyl)-O′-(2-methoxyethyl) polypropylene glycol (PEMA-g-PPG). An electron acceptor, 7,7,8,8-tetracyanoquinodimethane (TCNQ), was employed to activate the surface of the silver nanoparticles (AgNPs), leading to partial polarization. The AgNPs interacted with TCNQ as well as the PEMA-g-PPG graft copolymer to form facilitated olefin transport membranes, as characterized by Fourier transform infrared spectroscopy, UV–vis spectroscopy, and X-ray photoelectron spectroscopy. The PEMA-g-PPG/AgNP membrane activated by TCNQ showed long-term stability (with a mixed gas permeance of 7.8 GPU and propylene/propane selectivity of 17.5) of up to 100h, while that without TCNQ showed poor stability. The membrane based on PEMA-g-PPG showed better performance than those based on conventional matrices of poly(ethylene oxide) (PEO), poly(vinyl pyrrolidone) (PVP), or poly(ether-block-amide) (PEBAX).</P> <P><B>Highlights</B></P> <P> <UL> <LI> PEMA-g-PPG graft copolymer was synthesized via one-pot polymerization at 25°C. </LI> <LI> Solid-state facilitated transport membranes were prepared using PEMA-g-PPG/TCNQ/AgNP. </LI> <LI> Addition of TCNQ improved the olefin separation performance and long-term stability. </LI> <LI> The PEMA-g-PPG membrane showed better performance than those based on conventional matrices of PEO, PVP or PEBAX. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
