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 %.

In this Paper, we studied the mechanism that increases the network reliability and decreases network load in GMAHN environment based on the AODV routing protocol. This proposed algorithm is the research on the algorithm, minimizing network overhead by preventing unnecessary network overhead previously and adapting Local repair mechanism to efficient data transmission when route error happens in network, in GMAHN environment. To evaluate the proposed algorithm's performance, we analyzed the proposed algorithm and adapting in various experiment environment according to 5 experiment viewpoint such as node movement, gateway network zone, mobile node number, flow number. After evaluating the experiment, we confirmed better network improvement altogether through following result such as total average data reception rate's increase, average data transmission time's decrease, network overhead's decrease than existing GMAHN algorithm.

The purpose of this study was to gather and categorize the data of electrical energy sources for public office buildings in Taegu, South Korea. The fossil energy sources are not enough for all of us, as we know, to use. In a few days, it will be hard to utilize or find them neither under the earth nor the sea or around the world. New energy sources should be recommended and solar energy has been referred to substitute these limited sources. Prior to studying solar energy sources applied to public office buildings, necessary data should be systematically surveyed and lined up. This research ,therefore, will be a very important foundation for studying next thesis, solar energy project.

주조용 CD4MCU 이상 스테인리스강의 Mo 첨가에 따른 인장 및 부식 거동

장영환,손진일,김상식,이재현 대한금속재료학회 2005 대한금속·재료학회지 Vol.43 No.3

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.

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

Anaerobic digestion is a biological treatment process that has many advantages over the more conventional aerobic processes including low levels of excess sludge production, low space requirements and the production of valuable bigots. this study was carried out to evaluate the effect of organic loading rate on thermophilic(55℃) and mesophilic(35℃) anaerobic digestion. Moreover, fluorescent in situ hybridization(FISH) method was used for studying the microbial community it the reactors. The results of this study was as follows ; The stabilizing time of mesophiwic anaerobic reactors were shorter as approximately 20 days than 40 days of the thennrophiwic anaerobic reactors. The methane production of anaerobic reactors were independent of the feed substrate concentration and methanogens. The microbial diversity of two types of methanogenic reactor, mesophiwic (35℃) and thermophiwic (55℃), which had beet treating acetate-based artificial wastewater were compared. Methanogensis is carried out by microbial consortia consisting of bacteria and archer such as methanogens. the bacterial and archaic populations of all anaerobic reactors were investigated during a period of the process reflected by at accumulation of acetate. Archaea wore predominant it all reactors, and methanothrix-wike methanogens appeared it the mesophiwic anaerobic reactors with high feed substrate concentrations but it was tot preset it thermophiwic anaerobic reactors.

A laboratory scale BNR reactor was built to study the fate of N₂O production during BBNR(Bhortcut Biological' Nitrogen Removal. process and A/O process. Nitrous oxide(N₂O) is emitted from wastewater treatment processes. It is known as a greenhouse gas that contributes to global warming. Therefore it is importance to develop technology, that can suppress N₂O emission. Especially, N₂O emission' from the SBNR process was higher than that of A/O process. When a ono loading was increased(0.15 ∼ 0.6g/㎥day), dissolved N₂O concentration of nitrification was increased. And when nitrite concentration of aerobic basin was increased(0 ∼200 mg/L). N₂O emission rate was increased. As a results of this study, BURN process had an more effect on N₂O emission than A/O process.
