This study developed an ecological mapping technique with GIS database using the analyses of existing ecological survey reports and the change detection on the Nakdong river estuary. The data which are used to establish GIS DB include 2 Landsat TM images on Nov. 31, 1984 and May 17, 1997, 1:25, 000 topographical maps established by National Geography Institution and various ecological survey reports published by Busan metropolitan city government. The details for producing ecological map are as follows. At first, the current methods of ecomapping efforts and previous ecological surveys of Nakdong river estuary were carefully examined. Secondly, the land cover maps were created from the classified Landsat images of 1984 and 1997 for the spatiotemporal ecosystem analysis. Thirdly, the ecosystem was evaluated by using GIS ecological database based on the criteria of botany, zoology and water quality etc. Each criteria was reclassified into 3 stages which describe the overall quality of ecological condition. At last, the comprehensive ecological map was suggested as a prototype of ecosystem assesment and management tool with the discussion of further study. The findings of this study would be a milestone for preserving and managing the ecosystem.

The purpose of this study is to evaluate salivary flow rate,salivary pH, and cariogenic activity using unstimulatedsaliva of the head and neck cancer patients. Twenty threecancer patients (19 males, 4 females) who had undergonechemotherapy and radiation therapy and twenty four healthyvolunteers (14 males, 10 females) as a control were included. Salivary flow rate, salivary pH, and cariogenic activity usingunstimulated saliva were examined. Compared to saliva ofthe control group, salivary flow rate (p<0.001) and salivarypH (p<0.001) were significantly lower in head and neckcancer patients. The colony counts of Lactobacilli was higherin head and neck cancer patients (p<0.05) than in controlgroup. These salivary factors and cariogenic activity canincrease the prevalence of dental caries in head and neckcancer patients.

Immunological characterization of monoclonal antibodies used in rapid influenza diagnostic test for detection of the 2009 pandemic influenza A(H1N1)pdm09 infection

Yi, Hwajung,Lee, Mi-Seon,Lee, Joo-Yeon,Lee, Hae Kyung,Kang, Chun Springer-Verlag 2015 The journal of microbiology Vol.53 No.2

<P>Since the 2009 pandemic, monoclonal antibodies (mAbs) for rapid influenza diagnostic tests (RIDT) have been developed for specific diagnostics of pandemic viral infection. Most of the mAbs were poorly characterized because of urgency during the pandemic. Further characterization of the mAbs for RIDTs would be beneficial for understanding the immunological properties of the pandemic virus and utilizing the mAbs for other research purposes. In this study, it was confirmed that two mAbs (138 and D383) in an RIDT for H1N1pdm09 diagnostics were able to detect H1N1pdm09 virus through enzyme-linked immunosorbent assay (ELISA) and immunofluorescence assay (IFA). Also, the two mAbs exhibited reactivity to hemagglutinins (HAs) of both the H1N1pdm09 and 1918 H1N1 viruses; therefore, the RIDT using the mAbs could detect HAs of H1N1pdm09 and also HAs of 1918 H1N1-like strains. In an extension to our previous study, the epitopes (Sa antigenic site and the interface area of F' and vestigial esterase subdomahis on the HA1 domain of HA of H1N1pdm09) recognized by the mAbs were corroborated in depth by IFA with escape-mutants from the mAbs and mapping of the epitopes on the crystal structure of human H1N1 viral HAs. Collectively, these results imply that the mAbs for the RIDT may be suitable for use in studying the immunological properties of H1N1pdm09 viruses and that the Sa antigenic site and the interface area between F' and vestigial esterase subdomains on influenza viral HA recognized by the mAbs are immunologically conserved regions between H1N1pdm09 and 1918 H1N1.</P>

Background: Deficits of both ankle dorsiflexion range of motion (DFROM) and dynamic balance are shown in persons with chronic ankle instability and the elderly, with the risk of falls. Objects: This study aims to investigate the relationship between DFROM and dynamic balance in elderly subjects and young adults. Methods: Fifty-nine subjects were divided into three groups: ankle stability young group (SY), ankle instability young group (IY) and ankle stability older group (SO). We recruited three old subjects with ankle instability, but excluded them during a pilot testing due to the safety issue. DFROM was measured by weight bearing lunge test (WBLT) and dynamic balance was measured via star excursion balance test (SEBT) in anteromedial, medial, and posteromedial directions. The group differences in WBLT and SEBT and each group’s correlation between WBLT and SEBT were detected using the R statistical software package. Results: The dorsiflexion range of motion was significantly different between the SY, IY, and SO groups. The SO group showed the highest DFROM and IY group showed the lowest DFROM (SY: 45.88±.66 ˚ , IY: 39.53±1.63 ˚ , SO: 47.94±.50 ˚ ; p<.001). However, the SO group showed the lowest dynamic balance score for all SEBT directions (SY: 87.24±2.05 ㎝, IY: 83.20±1.30 ㎝, SO: 77.23±2.07 ㎝; p<.05) and there was no relationship between the dorsiflexion range of motion and dynamic balance in any group. Conclusion: Our findings suggest that ankle DFROM is not a crucial factor for dynamic stability regardless of aging and ankle instability. Other factors such as muscle strength or movement coordination should be considered for training dynamic balance. Therefore, we need to establish the rehabilitation process by measuring and treating ROM, balance, and muscle strength when treating young adults with and without ankle instability as well as elderly people.

Objective: To review indications and characteristics of all pregnant or puerperal woman who admitted to the intensive care unit (ICU) of tertiary care center over 22-year period. Methods: A retrospective analysis was done for all pregnant or puerperal women, who admitted to the ICU of our institution over 22-year period from September 1994 to October 2015. Clinical characteristics including the indications of ICU admission, the amount of transfusion, duration of hospital stay were collected by review of medical records. Results: During this 22-year period, 176 women required ICU admissions. Among 176 women admitted to the ICU, 118 (67.0%) women delivered in our institution. Because 53,689 deliveries took place in our institution during the study period, the incidence of ICU admission among parturients showed 2.2 per 1000 deliveries. The most common obstetric reason for admitting to the ICU was postpartum hemorrhage (54.5%), followed by hypertensive disorders (19.3%), sepsis (3.4%), and embolism (2.8%). Among postpartum bleeding cases, the median transfusion amount of packed red blood cells, platelet concentrate, and fresh frozen plasma was 12 (0~55), 8 (0~105), 8 (0~53) units respectively. The median stay at ICU was 3 days (1~25 days) and the median hospital stay was 11 days (1~63 days). Overall maternal death rate was 5.1% (9/176), which included 3 cases of DIC due to postpartum hemorrhage, 2 cases of amniotic fluid embolism, 1 case of HELLP syndrome with intracranial hemorrhage, 1 case of pulmonary thromboembolism, 1 case of postpartum cardiomyopathy and 1 case of post-adrenalectomy bleeding due to pheochromocytoma. Conclusions: Our data provide useful clinical information showing that the incidence of ICU admission among parturients is 2.2 per 1000 deliveries in this tertiary hospital and postpartum hemorrhage was the most common reason for admitting pregnant or puerperal women to the ICU, followed by hypertensive disorders and non-obstetric causes.
