The proliferation of textual data in society currently is overwhelming, in particular, unstructured textual data is being constantly generated via call centre logs, emails, documents on the web, blogs, tweets, customer comments, customer reviews, *** the amount of textual data is increasing rapidly, users ability to summarise, understand, and make sense of such data for making better business/living decisions remains challenging. This paper studies how to analyse textual data, based on layered software patterns, for extracting insightful user intelligence from a large collection of documents and for using such information to improve user operations and performance.

Chronic Groin Pain (Inguinodynia) following inguinal hernia repair is a significant,though under-reported problem. Mild pain lasting for a few days is common following mesh inguinal hernia repair. However,moderate to severe pain persisting more than 3 mo after inguinal herniorrhaphy should be considered as pathological. The major reasons for chronic groin pain have been identified as neuropathic cause due to inguinal nerve(s) damage or non-neuropathic cause due to mesh or other related factors. The symptom complex of chronic groin pain varies from a dull ache to sharp shooting pain along the distribution of inguinal nerves. Thorough history and meticulous clinical examination should be performed to identify the exact cause of chronic groin pain,as there is no single test to confirm the aetiology behind the pain or to point out the exact nerve involved. Various studies have been performed to look at the difference in chronic groin pain rates with the use of mesh vs non-mesh repair,use of heavyweight vs lightweight mesh and mesh fixation with sutures vs glue. Though there is no convincing evidence favouring one over the other,lightweight meshes are generally preferred because of their lesser foreign body reaction and better tolerance by the patients. Identification of all three nerves has been shown to be an important factor in reducing chronic groin pain,though there are no well conducted randomised studies to recommend the benefits of nerve excision vs preservation. Both nonsurgical and surgical options have been tried for chronic groin pain,with their consequent risks of analgesic sideeffects,recurrent pain,recurrent hernia and significant sensory loss. By far the best treatment for chronic groin pain is to avoid bestowing this on the patient by careful intra-operative handling of inguinal structures and better patient counselling pre-and post-herniorraphy.

Ca3–xAl2O6：x Eu^3＋（0.02≤x≤0.10） and Ca（2.92）Al2O6：0.04Eu^3＋,0.04M^＋（M^＋=Li^＋, Na^＋, and K^＋） phosphors were prepared by sol-gel method and their photoluminescence properties were investigated. The crystal structure of the annealed Ca3–xAl2O6：x Eu^3＋ and Ca（2.92）Al2O6：0.04Eu^3＋,0.04M^＋ phosphors was analyzed with X-ray diffraction（XRD）. The size and morphological characteristics of the annealed phosphors were investigated with a field emission scanning electron microscope（FE-SEM）. The photoluminescence properties were evaluated with a spectrofluorometer. The phosphors were effectively excited by the light of 396 nm and showed intense red emission at 616 nm, which originated from the 5D0→7F2 transition of Eu^3＋. Among the prepared phosphors, the Ca（2.96）Al2O6：0.04Eu^3＋ phosphor showed the strongest emission intensity and the highest color purity. The addition of alkaline metal ions（Li^＋, Na^＋, and K^＋） to Ca（2.96）Al2O6：0.04Eu^3＋ phosphor degraded the emission intensity and color purity.

化学农药在自然生态系统中浓度的迅速增加造成了农业土地和农产品的污染,这些污染通过食物链传播,并造成许多健康问题。使用碱性电解水是果蔬除农残的一种重要方法。本研究所用碱性电解水的p H为13.5,ORP为1200MV-900MV。本研究的主要目的是利用碱性电解水去除果蔬中的农药残留,以及在生产过程中喷施碱性电解水来提高农产品的质量。试验研究了西蓝花（和辣椒）在采收前以及采收后喷施碱性电解水的除农残效果;对比了碱性电解水处理、自来水处理、盐水处理、小苏打水处理和洗涤剂处理,五种方式除农残效果;优化了碱性电解水除农残的处理时间,以及明确了碱性电解水是否能进行重复使用等问题。试验进一步研究在樱桃番茄的生产过程中喷施碱性电解水对植物氧化应激指标“丙二醛”含量的影响,并测定了番茄的单果重、糖含量、维生素C和β-胡萝卜素的含量,从而较系统的研究了在樱桃番茄生产过程中喷施碱性电解水对樱桃番茄品质的影响。试验结果表明:采收前和采收后施用碱性电解水能有效的降低农残;5种除农残效果的大小为:碱性电解水＞洗涤剂＞小苏打水＞食盐水＞自来水;喷雾处理和浸泡处理作为2种利用碱性电解水除农残的方式,均在处理2分钟后具有最佳的除农残效果;在利用碱性电解水除农残过程中,碱性电解水可以连续重复利用。在樱桃番茄的生产过程中,喷施碱性电解水能有效的降低植物氧化应激指标“丙二醛”的含量;喷施碱性电解水能有效的提高樱桃番茄的单果重、糖含量、维生素C和β-胡萝卜素的含量,从而有效的提高樱桃番茄的品质。综上所述,在农产品生产过程中应用碱性电解水,可以有效去除各种果蔬中的农药残留,同时提高蔬菜的品质。碱性电解水在蔬菜的生产过程中具有广阔的应用前景。
