Soil autotrophic bacterial communities play a significant role in the soil carbon (C) cycle in paddy fields, but little is known about how rhizosphere soil microorganisms respond to different long-term (35 years) fertilization practices under double rice cropping ecosystems in southern China. Here, we investigated the variation characteristics of rhizosphere soil RubisCO gene cbbL in the double rice ecosystems of in southern China where such fertilization practices are used. For this experiment we set up the following fertilizer regime: without any fertilizer input as a control (CK), inorganic fertilizer (MF), straw returning (RF), and organic and inorganic fertilizer (OM). We found that abundances of cbbL, 16S rRNA genes and RubisCO activity in rhizosphere soil with OM, RF and MF treatments were significantly higher than that of CK treatment. The abundances of cbbL and 16S rRNA genes in rhizosphere soil with OM treatment were 5.46 and 3.64 times higher than that of CK treatment, respectively. Rhizosphere soil RubisCO activity with OM and RF treatments increased by 50.56 and 45.22%, compared to CK treatment. Shannon and Chao1 indices for rhizosphere soil cbbL libraries with RF and OM treatments increased by 44.28, 28.56, 29.60, and 23.13% compared to CK treatment. Rhizosphere soil cbbL sequences with MF, RF and OM treatments mainly belonged to Variovorax paradoxus, uncultured proteobacterium, Ralstonia pickettii, Thermononospora curvata, and Azoarcus sp.KH33C. Meanwhile, cbbL-carrying bacterial composition was obviously influenced by soil bulk density, rhizosphere soil dissolved organic C, soil organic C, and microbial biomass C contents. Fertilizer practices were the principal factor influencing rhizosphere soil cbbL-carrying bacterial communities. These results showed that rhizosphere soil autotrophic bacterial communities were significantly changed under conditions of different long-term fertilization practices Therefore, increasing rhizosphere soil autotrophic bacteria community with crop residue and organic manure practices was found to be beneficial for management of double rice ecosystems in southern China.

세계시장에서 다양한 생수가 제공되고 시장이 확대되는 것은 생수 브랜드에 대한 관심과 수요욕구가 커지고 있음을 보여준다. 브랜드이미지 인지를 명확하고 기능적이며 감성적인 가치 명품화를 하기위한 본 연구는 먼저 매슬로우의 욕구계층 이론 및 통합 마케팅 개념 이론 등 관련 문헌에 대하여 충분한 선행연구를 진행한 후, 욕구계층을 생수브랜드에 대한 통합적 마케팅(IB4P) 관점에서 분석하고 해석하였다. 출시된 10개 글로벌 생수 브랜드의 대상으로 IB4P의 전략 분석결과, Price 측면에서는 생리적 욕구 만족보다는 소속감, 즉 자기 존중 욕구를 만족시킬 수 있어야 하며, Place전략에서는 차별화 할 수 있는 새로운 판매 유통과 다양한 장소에서 판매가능 하도록 유통 환경을 개선하여야 하며, Product전략은 기존 제품과 차별화되는 병 용기 디자인, 색상으로 명품 고급화 제품이라 인식되어 자기존중, 사회적 존경의 욕구를 충족시킬 수 있어야 하며, Promotion전략은 몸에 유익한 물을 마신다는 경험을 제공하거나, 제품의 인지와 감성적 가치가 실현될 수 있다는 욕구가 충족 되어야 한다. IB4P 마케팅 전략은 생수 브랜드뿐만이 아니라 모든 제품 브랜드 이미지에 사용자단계별 욕구 형성을 통하여 통합적 4P요소를 효과적으로 추출할 수 있는 기초 토대를 마련한 결과를 얻을 수 있었다. A Variety of bottled water is being provided and its dominance is getting expanded in the world market. In consideration of such fact, it seems that interests and demand on bottled water brands are getting increased. For clearly recognition of a brand image and emotional valve of premium bottled water brand , the customers’ demand on a brand can be compared and classified through five type of desire shown in the Maslow’s need hierarchy theory and with this, emotional and functional values of bottled water brands are examined based on effective and integrated marketing IB4P. First, in this study it based on Maslow’s hierarchy of needs and Intergrated Marketing metrology study. Then, the point of bottled water brands analyzed by intergrated marketing(IB4P). the Marketing 4P information of bottled water brands as well as appealing types of each bottled water brand depending on consumers’ desire (Maslow’s hierarchy of needs) were analyzed among recently released 10 premium bottled water brands. Such analysis was conducted through analysis matrix. According to the results, the needs of belongingness and self-esteem had to be satisfied rather than physiological needs when it came to price. For place strategy, distribution environment should be improved to promote product sales in various distribution channels based on development and differentiation of new sales distributions. Regarding product strategy, the need for esteem from the society and others should be satisfied as bottled design and color that can be differentiated from existing products are understood to be more prestigious. For promotional strategy, experience as if drinking physically beneficial water should be provided or cognitive properties as well as emotional values of a product should be realized. The brand marketing strategy of IB4P can effectively derive 4P elements to form brand image.

Ileus tube placement combined with laparoscopy in the treatment of refractory small bowel obstruction: Case series and literature review

Post-surgery small bowel obstruction (SBO) has substantial morbidity and mortality. Even with refinement of surgical technique, SBO still remains challenging with the most common causes of acute hospital admission. Most SBOs can be managed with conservative treatment. However, the pal-liative methods may fail to relieve the symptoms in some clinical settings. Currently, laparotomy is the standard of care for difficult SBO. And lapa-roscopy offers an alternative approach for operative intervention in SBO and was first described by Bastug et al in 1991. Emerging literature dem-onstrated that laparoscopic surgery for SBO is less invasive, resulting in a shorter hospital stay than open surgery. And most recurrent adhesive SBO can be managed with ileus tube placement. This case series is to evaluate the efficacy of transnasal ileus tube placement combined with laparoscopic surgery in the treatment of consecutive 5 cases of refractory SBO post oncologic gastrointestinal surgery.

The pressure fluctuation characteristics in a Francis hydro-turbine running at partial flow conditions were studied based on the chaotic dynamic methods. Firstly, the experimental data of pressure fluctuations in the draft tube at various flow conditions was de-noised using lifting wavelet transformation, then, for the de-noised signals, their spectrum distribution on the frequency domain, the energy variation and the energy partition accounting for the total energy was calculated. Hereby, for the flow conditions ranging from no cavitation to severe cavitation, the chaos dynamic features of fluctuation signals were analyzed, including the temporal-frequency distribution, phase trajectory, Lyapunov exponent and Poincaré map etc. It is revealed that, the main energy of pressure fluctuations in the draft tube locates at low-frequency region. As the cavitation grows, the amplitude of power spectrum at frequency domain becomes larger. For all the flow conditions, all the maximal Lyapunov exponents are larger than zero, and they increase with the cavitation level. Therefore, it is believed that there indeed exist the chaotic attractors in the pressure fluctuation signals for a hydro-turbine.
