Purpose: BOOP and NSIP also share similar clinical features such as subacute flu-like illness, the finding of bronchoalveolar lavage, the result of pulmonary function test and more favourable outcome than usual interstitial pneumonia(UIP). The author try to compare the HRCT findings of NSIP with BOOP by pattern and distribution of diseases. Materials and Methods: HRCT findings of histopathologically proven NSIP(Group Ⅰ; 6, Group Ⅱ; 7, Group Ⅲ; 2) in 15 patients(5 male, 10 female, age range, 39-69 years; mean age, 53 years), BOOP in 15 patients(6 male, 9 female, age range, 26-76 years; mean age, 52 years) were reviewed retrospectively. Results: The common pattern of the two diseases was admixed consolidation, ground glass attenuation & reticular densities with/without architectural distortion(NSIP; 53.3%, BOOP; 46.7%). The main component of the pattern wan predominantly consolidation(NSIP; 46.7%, BOOP; 73.3%) and ground glass attenuation(NSIP; 40.0%, BOOP;20.0%). Architectural distotion was more provinent finding with NSIP(mild ; 3, moderate ; 4, severe; 2) compared with BOOP(mild; 7, moderate; 2, severe; 0). The predominant overall distribution was lower lung, peribronchovascular & peripheral lung field in both of the two entities(NSIP;73.3%, BOOP; 73.3%). Peribronchovascular involvement was more common with NSIP(100%) than BOOP(80%), whereas peripheral involvement was more common with BOOP(93.3%) than NSIP(80%). Conclusion: The HRCT findings of NSIP and BOOP were similar in pattern and distribution. But NIP manifested more frequently ground-glass attenuation, whereas BOOP showed more frequently consolidation. Architectural distortion was more severe with NSIP than BOOP. NSIP invoved more frequently peribronchovascular space and BOOP were more common in peripheral lung field.

This paper proposes an automated crack evaluation technique for a high-rise bridge pier using a climbing robot. The proposed technique enables to automatically detect and quantify the bridge pier cracks even where cannot easily access by human for visual inspection. To achieve it, high quality images are obtained by scanning the vision cameras embedded on the climbing robot along the bridge pier surface. Then, a feature extraction-based image stitching algorithm is newly developed and applied for establishing the entire region of interest (ROI) images. The ROI images are then processed with a semantic segmentation algorithm for automated crack detection. Finally, the detected cracks are precisely quantified by a crack quantification algorithm. The proposed technique is validated using in-situ test data obtained from Jang-Duck bridge located at Gangneung city, South Korea. The test results reveal that the proposed technique successfully evaluate the bridge pier cracks with precision of 90.92 % and recall of 97.47 %.

We isolated a toluene degrading bacterium from the bioactive foam reactor(BFR) which designed to remove volatile organic compounds(VOCs) from the contaminated air. In order tofind the taxonomic and phylogenetic relationship with known bacteria, the partial sequence of 16S ribosomal DNA gene was analyzed. The isolated bacterium was classified as Pseudomonas sp. based on the close relationship to bacteria belonging to this genus. From the sequence, we designed the appropriate DNA probe which will be useful to detect this bacterium with the molecular methods such as FISH. The isolated bacterium and designed probe will be helpful to optimize the operating conditions and to improve the efficiency of BFR in detoxification of VOCs.

In the present study, the effect of Mo contents on the microstructure, tensile and corrosion behaviors of as-solutionized CD4MCU cast duplex stainless steel was examined. The polarization test was conducted in 3.5% NaCl +5% H₂SO_(4) aqueous solution for general corrosion resistance and the slow strain rate tests were also conducted in air and 3.5% NaC1+5% H₂SO_(4) aqueous solution to study the stress corrosion cracking (SCC) of the present alloy. A substantial microstructural evolution of CD4MCU cast duplex stainless steel was observed with different Mo contents, which in turn affected the tensile and corrosion behaviors significantly. The beneficial effect of Mo on improving the corrosion and the SCC resistances was largely overwhelmed by this variation of microstructural characteristics. The relationship between the microstructural evolution and the tensile and corrosion behavior of CD4MCU cast duplex stainless steels with different Mo contents was discussed based on the optical and SEM micrographic and fractographic observations.

단축질소제거공정에서의 C/N비에 따른 N₂O발생 특성에 대한 연구

장광언,황선진,장현섭 경희대학교 2003 環境硏究 論文集 Vol.12 No.-

Nitrous oxide(N₂O) is produced as by-production of nitrogen removal system from wastewater and associated with many parameter(such as DO, pH, Temperature, C/N ratio, accumulation of nitrite etc...). Especially SBNR (Shortcut Biological Nitrogen Removal) process have high potential of N₂0 production, but research about this relationship is insufficient. Ammonia concentration of Influent was 600 ppm and 2 sets of reactor (for A/O process and SBNR process) were used. Based on the results of this study A/O process (conventional nitrification and denitrification) was effected by C/N ratio but SBNR process did not. And N₂O production of BSNR oxic tank was observed constantly.
