The affect of recirculated exhaust gas on exhaust emissions under four kinds of nozzle tip with the different fuel consumption rate are experimentally investigated by using an once-through boiler with FGR system. The purpose of this study is to develop the is to develop FGR control system for reducing NO. in a boiler. Intake and exhaust oxygen concentration, and equivalence ratio are applied to discuss the effect of FGR rate on exhaust emissions at various fuel consumption rates. It is found that NO. emissions are decreased, while soot emissions are increased owing to the drop of intake and exhaust oxygen concentrations, and the rise of equivalence ratio as FGR rates are elevated.<br/>

Purpose: Intestinal failure (IF) is a complex clinical condition requiring a multi-disciplinary team approach. Our objective was to set up the treatment protocols and education documents for IF patients for development of intestinal rehabilitation programs in our hospital. Methods: We compared the number of inpatients, length of hospital stay, mode of nutrition and calorie supply at discharge, and the frequency of blood transfusions before and after quality improvement of multidisciplinary activities, in order to evaluate the indirect effects of new protocols and training materials and for development of the intestinal rehabilitation system. Results: We integrated eleven protocols for treatment and monitoring and seven educational materials for patients and caregivers. We compared indirect effects before and after the quality improvement activities. The number of IF patients hospitalized was reduced from 12 to 9. The mean days of hospital stay was decreased from 322 days to 73 days, the average number of monthly blood transfusions was also reduced from 1.8 to 0.3. In addition, the percentage of patients administered enteral nutrition and calories supplied was increased at discharge. Conclusion: By integrating IF protocols and education materials for IF patients, we found possible indirect effects of intestinal rehabilitation using a multidisciplinary team approach.

Background: Churg-Strauss syndrome (CSS) is a systemic small-vessel vasculitis which predominantly involves the lung, skin, gastrointestinal tract and the nervous system, but here we report a CSS case involving the mediastinal lymph node (LN) and gallbladder (GB). Case report: A 43-year-old woman with 2-year history of asthma was admitted with dyspnea and wheezing. The patient showed marked peripheral eosinophilia and multiple mediastinal lymphadenopathy with multifocal pneumonic consolidations on both lower lungs in chest computed tomography (CT). The patient was treated with methylprednisolone and antibiotics assuming asthma exacerbation with pneumonia. Following 7 days of treatment, dyspnea improved with near disappearance of pulmonary in. ltration. However, during steroid tapering, acute cholecystitis with multiple GB stones developed. Follow-up chest CT showed much improved consolidations, but no significant change of enlarged mediastinal LN. In addition, serum P-anti-neutrophil cytoplasmic antibody was positive. Because she had persistent abdominal pain requiring cholecystectomy, co-operation of cholecystectomy and concurrent wedge resection with mediastinal LN biopsy was performed for tissue confirmation. Necrotizing and granulomatous vasculitis with eosinophil in filtrates was observed in the specimens of GB, lung, and LN, respectively. Furthermore, skin biopsy was performed from purpuric lesions on both dorsum and it showed leukocytoclastic vasculitis with eosinophil predominance. finally, she was con. rmed as CSS based on asthma, eosinophilia, polyneuropathy, pulmonary in filtrates and extravascular eosinophils by biopsy confirmation on multiple sites. After 4 weeks of treatment with methylprednisolone 60mg/day, her associated symptoms and eosinophilia were improved. Conclusion: We herein report an unusual case of CSS manifested by mediastinal lymphadenopathy with lung consolidation and necrotizing eosinophilic cholecystitis, which can be misdiagnosed as pneumonia with reactive LN enlargement and stone induced cholecystitis. Thus, involvement of CSS in other organ should not be overlooked.

The Asian corn borer, Ostrinia furnacalis, over-winters as the last instar larva in Suwon and undergoes diapause during the over-wintering, and it has been postulated that most of the over-wintering larvae be originated from the larvae of 2nd and 3rd generation (Jung et al., 2008). The over-wintered larvae pupate next year and 50% of emerged adults occur by the early June. In order to know whether the emergence has synchronism among over-wintering larvae regardless of the time entering into diapause or not, neonate larvae were reared on artificial diet at two-week intervals from May 28 to Sep. 28, 2008 in an outside condition and their emergence dates were recorded. The over-wintering larvae occurred from the colony treated at Jul. 20, 2007, and totally emerged from May 11 to Jul. 6, 2008. The 50% date of cumulative emergence was June 3, 2008. The maximum success of over-wintering occurred in the colony treated at Aug. 17, whereas any non-over-wintering larvae were not observed from the following colonies. Although the durations of emergence overlapped partially among the colonies treated at different times in the previous year to show a synchronism at some extent, the first and last colonies treated in the previous year showed a pattern of fast emergence. This result suggested that the duration necessary for diapause termination be different according to the time entering into diapause.

Aphis gossypii was widely distributed throughout the tropical, subtropical and temperate zone. The chemical control of A. gossypii is becoming problem because it was rapidly appeared resistance expression to chemicals. We will attempt to resolve the this problem using RNAi technique. Besides, RNAi technology can be helpful to study the target genes of A. gossypii. In this study we produce cDNA library construction using gateway cloning system for selecting target gene in order to control of A. gossypii using RNAi. As a result, the 100-400bp of insert size, which is appropriate for RNAi was confirmed. Most of insert gene is associated with A. gossypii, after that insert sequence was compared with DNA databases and EST databases using NCBI blast search. Consequentially, A. gossypii of cDNA library with the titer of 3.15x105 clones were completed. And we will perform the LR recombination to transfer cDNA library into TRV2 (tobacco rattle virus) vector with att site. Then, after performing transformation using Agrobacterium tumefaciens (GV 2260), we inoculated to cucumber with A. tumefaciens. An insecticidal effect or a repellent activity against A. gossypii by changing behavior in transgenic cucumber plants were conformed. Also, the selecting target gene in order to control A. gossypii using RNAi may be provided.
