  • Background: The Purpose of this study was investigated the effects of the Self Sling Suspension on the numbness, radiated pain, visual analogue scale (VAS), Cobb's angle, Jochumsen's depth, neck disabliity index (NDI). Methods: This study was carried out with a 4 forward head posture (FHP) & 4 herniated nucleus pulposus (HNP) survivors. Outcomes such as the Numbness, Radiated Pain, VAS, Cobb's angle, Jochumsen's depth and NDI were measured pre- and post-intervention for both groups. Results: 2 HNP decrease was found numbness & radiated pain. After the intervention, was decreased VAS, NDI and was increased Cobb's angle, Jochumsen's depth. Conclusions: Applying Self Sling Suspension treatment to FHP & HNP patients proved to have a positive effect.

  • In this paper, the geometry effectiveness and contact modes as functions of real contact length on a cap ring have been analyzed for high pressure sealing mechanism in reciprocating actuator. The reaction force and elastic strain energy density are very important parameters for analyzing the sealing performance of an ACGT ring seal. For the high pressure of 800bar and the maximum speed of 3m/s, the main piston is reciprocating along the linear line against the cylinder wall. The computed results indicate that the length ratio of a cap ring is more influential design parameter compared to that of the tribological contact mode. Thus, this paper recommends the discrete contact area rather than a conventional flat contact model. Especially, the sealing capacity is more improved when the length ratio of a cap ring is below 0.625.

  • Purpose : This study intended to improve the quality of prehospital emergency care for patients with dyspnea by figuring out the current situations and problems based on run-sheets of 119 emergency medical technicians (EMTs). Methods : A total of 336 dyspnea patients were transferred to G university hospital by 119 ambulances from January 1, 2011 to December 31, 2011. Results : The data were analyzed by SPSS 19.0. Patients over 60 years old accounted for 57.2% and 48.4% had the history of heart disease. Among the heart disease patients, 31.7% complained of dyspnea and chest pain. The vital sign measurement performance by 119 EMTs increased compared to previous study. The number of prehospital treatment by 119 EMTs significantly increased depending on the mental state of the patients. Conclusion : 119 EMTs should remind the heart disease and other past history of the patients when they perform the dyspnea patient care.

  • A new species belonging to the genus Alternaria was isolated from the necrotic leaf spots of Brassica rapa subsp. pekinensis in Yuseong district, Daejeon, Korea. It is an occasional isolate, not an etiological agent, which is morphologically similar to A. broccoli-italicae, but differs in conidial size and conidiophore shape. Phylogenetic analysis using the sequence datasets of the internal transcribed spacer (ITS) region of the rDNA, glyceraldehyde-3-phosphate dehydrogenase (gpd), and plasma membrane ATPase genes showed that it is distantly related to A. broccoli-italicae and closely related to Alternaria species in the section Pseudoalternaria, which belonged to a clade basal to the section Infectoriae. Morphologically, the species is unique because it produces solitary conidia or conidial chains (two units), unlike the four members in the section Pseudoalternaria that produce conidia as short branched chains. It exhibits weak pathogenicity in the host plant. This report includes the description and illustration of A. brassicifolii as a new species.

  • Granitic complex in the Woosanbong area is composed of schistose granite, two-mica granite, biotite granite, porphyritic granite and pink feldspar granite in order of intrusion. In their boundary aspects, the gradational change between porphyritic granite and pink feldspar granite is observed in field relations. All the granites of the complex are classified to quartz monzonite by the modal compositions following Bateman's classification (1961) with the exception of pink feldspar granite which belongs to granite according to the petrographical classification. The first three granites are characterized by highly development of vein and/or lens-like pegmatites in their bodies, and two others contain green hornblende uniquely. These leucocratic two-mica granite shows an unusual character in ratio of muscovite to biotite 1: 0.7 to 1:13, and contains dominantly microcline. The content of muscovite varies in places in the field. Under the polarizing microscope it is revealed that the muscovite flakes occur as the products altered from biotite partly or completely, and it usually associates with chlorite flakes nearby. These features, therefore, suggests that biotite probably has been altered to muscovite and chlorite by hydration during deuteric processes. At the same stage, sericitization of plagioclase by the hydrolytic decomposition, and transformation of orthoclase to microcline may be taken place. Accordingly, it is obviously permissible to consider the two-mica granite as a kind of 'apo-granite' by deuteric alterations during the consolidation of magma.

  • Fifty two infants and young children hospitalized in the pediatric department of Hanyang University Hospital with acute gastroenteritis from February through April 1982 were examined for the evidence of infection with rotavirus by electron microscopic technique and enzyme-linked immunosorbent assay(ELISA). Of 52 patients examined, rotaviruses were detected in stools of 11 patients(21%) by EM technique and 16 patients(31%) by ELISA. But there was no significant statistical difference between the two methods(Z=1.2<2). During the study period, rotaviruses were detected in stools of 6(38%) of 16 patients in February, 10(30%) of 33 patients in March, and none of 3 patients in April. The age of the 16 patients who shed the rotaviruses in their stools ranged from 3 months to 6 years, and 12 patients(75%) were between 6 and 24 months. Our study suggests that the rotaviral gastroenteritis of infants and young children in Korea might have similar frequency, seasonal variation, and age distribution with other countries in temperate zone.

  • This study investigates the variation and spatial distribution of nitrogen dioxide($NO_2$) concentrations measured with passive diffusive samplers at 40 curbside points in Daejeon. Average $NO_2$ concentration was $39.8{\pm}18.0\;ppb$ (n=1,127) and the significant difference in concentrations by regional groups (Dong-gu, Jung-gu, Seo-gu, Daedeok-gu, Yuseong-gu) was not observed. The frequency distribution of $NO_2$ concentration was found to be a normal distribution with the high frequency in the concentration range of 30 to 40 ppb (20 to 25%). Average $NO_2$ concentration measured during the rainy periods was lower than that measured during the non-rainy periods and the decrease of concentration by rainfall was about 16% (7 ppb). The variation of $NO_2$ concentrations measured by passive diffusive samplers during the sampling period was similar to that continuously measured at the air quality monitoring station.
