Adherence to the AASLD guidelines began at71.7% to 75.9% from 2008 to 2010, and then it fluctuated between 49.2% and 73.8% from 2011 to 2016.

Sorption enhanced catalytic CF4 hydrolysis with a three-stage catalyst-adsorbent reactor

Frontiers of Chemical Science and Engineering 2017年第4期11卷 537-544页

作者： jae-Yun Han Chang-Hyun Kim Boreum Lee Sung-Chan Nam Ho-Young Jung Hankwon lim Kwan-Young Lee Shin-Kun Ryi . Advanced Materials and Devices Laboratory Korea Institute of Energy Research (KIER) Daejeon 34129 Korea..

Department of Environment and Energy Engineering Chonnam National University Gwangju 61186 Korea.. Department of Chemical and Biological Engineering Korea University Seoul 136-701 Korea

In this study, we developed a three-stage catalyst-adsorbent reactor for the catalytic hydrolysis of CF4. Each stage is composed of a catalyst bed followed by an adsorbent bed using Ca（OH）2 to remove HF. The three stages are connected in series to enhance the hydrolysis of CF4 and eliminate a scrubber to dissolve HF in water at the same time. With a 10 wt-% Ce/AlaO3 catalyst prepared by the incipient wetness method using boehmite and a granular calcium hydroxide as an adsorbent, the CF4 conversion in our proposed reactor was 7%-23% higher than that in a conventional single-bed catalytic reactor in the temperature range of 923-1023 K. In addition, experimental and numerical simulation （Aspen HYSYS） results showed a reasonable trend of increased CF4 conversion with the adsorbent added and these results can be used as a useful design guideline for our newly proposed multistage reactor system.

Characterizations of organic compounds in diesel exhaust particulates

Journal of Environmental Sciences 2015年第8期27卷 171-183页

作者： jaehyun lim Cheolsoo lim Sangkyun Kim Jihyung Hong Division of Global Environment Research National Institute of Environmental Research Department of Climate and Air Quality Research National Institute of Environmental Research

To characterize how the speed and load of a medium-duty diesel engine affected the organic compounds in diesel particle matter（PM） below 1 μm, four driving conditions were examined. At all four driving conditions, concentration of identifiable organic compounds in PM ultrafine（34–94 nm） and accumulation（94–1000 nm） modes ranged from 2.9 to 5.7 μg/m3 and 9.5 to 16.4 μg/m3, respectively. As a function of driving conditions, the non-oxygencontaining organics exhibited a reversed concentration trend to the oxygen-containing organics. The identified organic compounds were classified into eleven classes： alkanes,alkenes, alkynes, aromatic hydrocarbons, carboxylic acids, esters, ketones, alcohols, ethers,nitrogen-containing compounds, and sulfur-containing compounds. At all driving conditions,alkane class consistently showed the highest concentration（8.3 to 18.0 μg/m3） followed by carboxylic acid, esters, ketones and alcohols. Twelve polycyclic aromatic hydrocarbons（PAHs）were identified with a total concentration ranging from 37.9 to 174.8 ng/m3. In addition, nine nitrogen-containing polycyclic aromatic compounds（NPACs） were identified with a total concentration ranging from 7.0 to 10.3 ng/m3. The most abundant PAH（phenanthrene）and NPACs（7,8-benzoquinoline and 3-nitrophenanthrene） comprise a similar molecular（3 aromatic-ring） structure under the highest engine speed and engine load.

Primary intestinal lymphangiectasia with generalized warts

引用

World Journal of Gastroenterology 2015年第27期21卷 8467-8472页

作者： Soon jae Lee Hyun Joo Song Sun-Jin Boo Soo-Young Na Heung Up Kim Chang lim Hyun Department of Internal Medicine Jeju National University School of Medicine Department of Pathology Jeju National University School of Medicine

Primary intestinal lymphangiectasia(PIL) is a rare protein-losing enteropathy with lymphatic leakage into the small intestine. Dilated lymphatics in the small intestinal wall and mesentery are observed in this disease. Laboratory tests of PIL patients revealed hypoalbuminemia, lymphocytopenia, hypogammaglobulinemia and increased stool α-1 antitrypsin clearance. Cell-mediated immunodeficiency is also present in PIL patients because of loss of lymphocytes. As a result, the patients are vulnerable to chronic viral infection and lymphoma. However, cases of PIL with chronic viral infection, such as human papilloma virus-induced warts, are rarely reported. We report a rare case of PIL with generalized warts in a 36-year-old male patient. PIL was diagnosed by capsule endoscopy and colonoscopic biopsy with histological tissue confirmation. Generalized warts were observed on the head, chest, abdomen, back, anus, and upper and lower extremities, including the hands and feet of the patient.
