CO2捕集与存贮（CCs）是一项应对全球变暖的有潜力的措施。钢铁联合企业是一个巨大的CO2排放源,应该最优先考虑捕集CO2。地球革新技术研究所（RITE）开发出一种低成本的CO2捕集系统,采用化学吸收法脱除高炉煤气中的CO2（COCs项目,2004—2008财年）。在该项目中,RITE进行了新的化学溶剂的开发,以减少再生能量的消耗,因为它对CO2捕集的成本有直接影响。首先使用气体洗涤瓶,通过筛选测试评估溶剂对CO2的吸收/解吸速率,用微分反应量热计测量反应热。通过这些试验,对溶剂进行筛选后,用处理CO2能力为1 t/d的试验设备对高性能的待选新溶剂进行评估。通过上述试验,能对新的混合胺溶剂（称RITE溶剂,包括RITE-5与RITE-6）作出评价。RITE溶剂具有中等偏低的反应热和中等偏高的吸收率。在1t/d的试验设备上评估出这两种溶剂的再生能量分别为3.3 GJ/t、3.1 GJ/t,比30%（质量分数）的MEA（单乙醇胺,4.0 GJ/t）要低得多。如果对操作与设备参数进行优化,RITE-5与RITE-6的再生能量预计有潜力降到2.65 GJ/t与2.5 GJ/t。COCs项目还开发出CO2捕集系统用的余热资源回收技术,用再生锅炉生产低成本蒸汽。联合使用RITE溶剂和余热回收系统,预计CO2的捕集成本要比30%MEA的方法几乎低50%。

Warthin’s tumor is the second most frequent neoplasm next to pleomorphic adenoma in the salivary gland. The tumor contains the epithelial oncocyte cells with the presence of rich-mitochondria and their surrounding abundant lymphocytes. A relatively new disease entity of IgG4-related disease frequently occurs in the salivary gland. However, the coexistence of Warthin’s tumor and IgG4-related disease is scarcely observed. We have recently experienced a rare case of Warthin’s tumor with IgG4-related sialadenitis. A 51-year-old man presented to our hospital, complaining of a mass with right submandibular tenderness and spontaneous pain. A computed tomography scan of the cervical region revealed a suspicion of lymph node proliferative disease, including malignant lymphoma. Elevated serum levels of IL-2R: 1843 U/ml (reference value 122 - 496 U/ml), IgG: 3430 mg/dl (reference value 861 - 1747 mg/dl), and IgG4: 3140 mg/dl (reference value 11 - 121 mg/dl) were observed. Other laboratory data showed within normal ranges. The cervical tumor was diagnosed as Warthin’s tumor by the findings of fine-needle aspiration cytology and biopsy examination. Immunohistochemistry revealed numerous IgG4- and IgG-positive cells with fibrosis surrounding the epithelial component of Warthin’s tumor, suggesting IgG4-rerated sialadenitis. Finally, we diagnosed the cervical tumor as Warthin tumor with IgG4-related sialadenitis. This is the second report describing a case of Warthin’s tumor with possible involvement of IgG4-related sialadenitis.

There appears to be the strong association between Helicobacter pylori （H pylori） and gastric cancer. We reviewed the latest evidences about the effects of H pylori infection on gastric carcinogenesis, classified into epidemiology, dynamics of gastric mucosal changes, DNA damages, virulence factors, host factors, and source of gastric malignancy. Through the considerable progress made in research into virulence factors resulting from differences between Hpylori strains, such as cagA positivity, as well as into host factors, such as gene polymorphisms, a diverse spectrum of H pyloriassociated diseases, including gastric cancer, is beginning to lend itself to elucidation. The impact of the novel hypothesis advanced by Houghton et al proposing bonemarrow derived stem cells （BMDC） as a potential source of gastric malignancy on evolving research remains to be seen with interest. Further progress in research into H pylori eradication as a viable prophylaxis of gastric cancer, as well as into the mechanisms of gastric carcinogenesis, is to be eagerly awaited for the current year and beyond.

A cellular model based on the Incrementally Modular Abstraction Hierarchy （IMAH） is a novel model that can represent the architecture of and changes in cyberworlds, preserving invariants from a general level to a specific one. We have developed a data processing system called the Cellular Data system （CDs）. In the development of business applications, you can prevent combinatorial explosion in the process of business design and testing by using CDs. In this paper, we have first designed and implemented wide-use algebra on the presentation level. Next, we have developed and verified the effectiveness of two general business applications using CDs： 1） a customer information management system, and 2） an estimate system.
