Targeted incentive direction refers to the motivation, namely, to what kind of content to implement incentive. It has signifi cant effect on incentive effect. According to American psychologist Maslow’s hierarchy of needs theory, people’s behavior motives originated in fi ve kinds of need, namely: the physiological needs, security needs, belonging needs, respect for the needs and the self-actualization needs. People need not set in stone, which is a developing process from low to high, but the process is not a cascade of discontinuous jumping, but a continuous, the evolution of wave. Under this general basis, we propose the cultural atmosphere for modern enterprise management that is novel and innovative.展开更多

The mineral N, Pand K fertilizers (as urea, calcium superphosphate and KCl respectively) were incorporated at 100,25, and 100 kg ha^(-1), respectively, and the various pesticides were applied at the recommendedrates. The results of the experiment demonstrated a decline in the microbial abundance and soilmicrobial biomass phospholipid contents with the advancement of crop growth, and significant changesin substrate utilization pattern of soil microbial population studied were observed with differentmanagement practices and at different growth stages. The principal component analysis (PCA) usingall 95-carbon sources (BIOLOG plates) gave good differentiation among the treatments, indicatingthat they have different patterns of carbon utilization under different habitats. The data showedthat diversity in microbial community continuously changed with the progression in crop stage,particularly at physiological maturity (PM) stage that was evident from the utilization of differentcarbon sources at various crop stages.展开更多

Methods:From January to December in 2012,a portion of the cataract patients were evaluated for the pattern of day ward management.Methods were as follows:1).Establish the cataract day ward. 2) Enroll the patients who met the following criteria: voluntary, local residents or outsiders who stayed in a hotel near the hospital, accompanied by family, and who had simple senile cataract without any systemic major diseases. 3) Establish the hospitalization process. 4) Analyze the nursing process. After cataract day surgery, the patients were followed for 2 hours and completed a questionnaire about their needs and sentiments. Results: A total of 3971 cases were observed in this study; 49 cases were switched to a normal pattern of hospitalization because of operative complications, 1 case had a strong desire to switch to a normal pattern of hospitalization because of ocular discomfort,8 cases went back to the hospital for treatment because of ocular pain,and 52 cases called on the phone to seek help. Overall, 3820 cases (96.2%) returned on time the next day to visit the doctor.No patients showed severe postoperative complications and 98% expressed great satisfaction with the day ward process.Only 200 cases expressed great concern about not knowing how to deal with postoperative pain,the changes in condition outside the hospital, the therapeutic effects,and the problem of expense reimbursement. Conclusion: Day ward cataract surgery is an efficient and safe mode, and has the potential to relieve the demand for inpatient beds and to ensure timely treatment of the patients. In addition,it helps the patients enjoy health care at public expense,reserving reimbursement for those who need to be hospitalized.Nurses should pay more attention to systemic evaluation of the patients, health education, and psychological guidance,and keep in close communication with doctors, which is the key to ensure the safety of day ward practice.展开更多

One way to improve the livability of compacted and congested cities like Hong Kong is through the provision of urban parks, an aspect that has largely been under-researched. This study focuses on how users perceive and utilize various facilities in the Kowloon Park. The findings revealed that the Kowloon Park is one of the most preferred parks in Hong Kong for both local residents and tourists. Users were quite satisfied with the park's facilities. Notably, the most important component of an urban park is its greenery. This is followed by water elements, seating places, and facilities for various recreational activities. The improvements users would like to see in urban parks include good design and management, meeting users' needs, overcoming barriers to use, and providing a high quality and varied experience for different groups in the community. The findings of this study provide a good basis to address park management issues from the users' perspective. In particular, parks should provide easy access, encourage optimum usage and enable complimentary improvements to the environment.展开更多

In Australia, singular temporal patterns for design storms have governed the inputs of hydrograph generation and in turn the design process of OSD for the last three decades. This paper raises the concern that many existing OSD systems designed using the singular temporal pattern for design storms may not be achieving their stated objectives when they are assessed against a variety of alternative temporal patterns. The performance of twenty real OSD systems was investigated using two methods:(1) ensembles of design temporal patterns prescribed in the latest version of Australian Rainfall and Runoff, and (2) real recorded rainfall data taken from pluviograph stations modeled with continuous simulation. It is shown conclusively that the use of singular temporal patterns is ineffective in providing assurance that an OSD will mitigate the increase to peak discharge for all possible storm events. Ensemble analysis is shown to provide improved results. However, it also falls short of providing any guarantee in the face of naturally occurring rainfall.展开更多

Correspondingly, the local government conducted an exploration of the organization and management mode in the field of planning and construction. The effective experiences have been accumulated, including working out a full coverage planning,taking the leading part in the urban-rural planning,and exercising whole space control over the disaster area. An innovation management mode named as "Five Generals Pattern"was implemented in the construction projects. In view that the rural housing reconstruction was a weak link, a new approach to improving the construction management was investigated,by means of strengthening on-site supervision,establishing a technical platform,and bolstering public participation.展开更多

But state nature reserves and local administration nature reserves under the regulations are only the approval system and embody the concept of protection. Management pattern of nature reserves can be divided into nine types. There are big differences in the nine patterns in management foundation and coordination ability of management because different management pattern occupies different resources of administration,personnel,financial and law enforcement. By analyzing management pattern,thirty-eight indexes in thirteen categories were selected to evaluate the management effectiveness of national nature reserves subordinate to the State Forestry Administration (SFA) . Results show that the management effectiveness of national nature reserves is good as a whole,and the management effectiveness is direct proportional to administration level. Provincial administration has the higher efficiency than municipal and county administration. Direct administration by governments at all levels has the higher efficiency than departments' administration at the same level.展开更多

The aim of this study is to share our experience with the management of 46 cases. Patients and method: We retrospectively analysed the medical records of 46 patients admitted with Fournier's gangrene between April 2005 and December 2011 in the urology unit of Aminu Kano Teaching Hospital. Data extracted from these include age, sex, hospital stay, premorbid diseases, mobility, mortality, laboratory investigations and treatments carried out. Results: Fourty six patients were admitted and managed for Fournier's gangrene during the study period. All the patients were male and mean age was 50 years (range 20 - 80 years). Five patients died (10.90%) mortality, 41 (89.10%) patients survived. The shortest hospital stay was 13 days and longest was 120 days. 45.7% of the patients had urethral stricture with watering can perineum as predisposing factor, 16 (34.80%) had diabetes mellitus, 7 (15.2%) had perineal injuries as the predisposing factors while 5 (10.90%) patients had uraemia and one patient (2.20%) each had bladder tumour and scrotal abscess as their predisposing factors, in 3 patients (6.50%) it was idiopathic. Only 34 (73.90%) patients had wound swab microscopy culture and sensitivity on admission. The culture grew Klebsiella spp. in 9 (26.50%), Staph aureus and E. coli in 5 (10.90%) of cases each, while Gram positive rod and Gram negative Cocci with 4 (11.80%) and 6 (17.60%) respectively. Conclusion: Fournier's gangrene which is a rapidly progressive, fulminant polymicrobial synergistic infection of the perineum and genitals, is now changing pattern. Extensive surgical debridement and broad spectrum intravenous antibiotics remain the mainstay of treatment.展开更多

Conclusion: Day ward cataract surgery is an efficient and safe mode, and has the potential to relieve the demand for inpatient beds and to ensure timely treatment of the patients. In addition,it helps the patients enjoy health care at public expense,reserving reimbursement for those who need to be hospitalized.Nurses should pay more attention to systemic evaluation of the patients, health education, and psychological guidance,and keep in close communication with doctors, which is the key to ensure the safety of day ward practice.
文摘The agricultural development in the less developed districts is a big challenge as they are resource poor regions and crops are grown under more risky agro-ecological conditions. In this paper, we conduct research on novel pattern of agricultural economy based on accurate information management system. Agricultural information is the agriculture prenatal, during and aider the information process, mainly to solve the problems in the development of agricultural production. Rural information includes rural economic information, rural management and related information, rural information culture and the rural social service information. Our system modifies the efficiency of managing materials which will largely enhance the economical result for the agricultural activities.

文摘Large-scale crop monocultures facilitate the proliferation and increasing prevalence of diseases and pest insects.Many studies highlight the impacts of plant diversification upon pathogens,and the population dynamics of insects and beneficial organism in agricultural ecosystems.These studies provide evidence that habitat manipulation techniques such as intercropping,relay,and rotation can significantly improve disease and pest management.This review introduces the concept of crop diversity,considers recent insights and mechanisms underlying crop diversity,and discusses its potential for improving sustainable agricultural practices.Recently,the phytobiomes resulting from increased crop diversity are increasingly recognized for their contribution to disease and pest control.Further,understanding the interactions between pathogens or pests with their host phytobiome may lead to novel options for the prevention of pests.Recent advances in the agricultural systems include:(i)a better understanding of the mechanisms of interactions between crop species and genotypes;(ii)ecological progress including a better understanding of the context-dependency of those interactions;and(iii)the role of microtopographic variation in agricultural systems for priming basal resistance to multiple pests and pathogens by intercropped crops.We also highlight recent progress in China and the potential options for habitat management and design that enhance the ecological role of biodiversity in agroecosystems.

文摘Hong Kong is a hyper-dense city with 7x10(6) people living in an area of 1100km(2). One way to improve the livability of compacted and congested cities like Hong Kong is through the provision of urban parks, an aspect that has largely been under-researched. This study focuses on how users perceive and utilize various facilities in the Kowloon Park. The findings revealed that the Kowloon Park is one of the most preferred parks in Hong Kong for both local residents and tourists. Users were quite satisfied with the park's facilities. Notably, the most important component of an urban park is its greenery. This is followed by water elements, seating places, and facilities for various recreational activities. The improvements users would like to see in urban parks include good design and management, meeting users' needs, overcoming barriers to use, and providing a high quality and varied experience for different groups in the community. The findings of this study provide a good basis to address park management issues from the users' perspective. In particular, parks should provide easy access, encourage optimum usage and enable complimentary improvements to the environment.
文摘On-site stormwater detention (OSD) is a conventional component of urban drainage systems, designed with the intention of mitigating the increase to peak discharge of stormwater runoff that inevitably results from urbanization. In Australia, singular temporal patterns for design storms have governed the inputs of hydrograph generation and in turn the design process of OSD for the last three decades. This paper raises the concern that many existing OSD systems designed using the singular temporal pattern for design storms may not be achieving their stated objectives when they are assessed against a variety of alternative temporal patterns. The performance of twenty real OSD systems was investigated using two methods:(1) ensembles of design temporal patterns prescribed in the latest version of Australian Rainfall and Runoff, and (2) real recorded rainfall data taken from pluviograph stations modeled with continuous simulation. It is shown conclusively that the use of singular temporal patterns is ineffective in providing assurance that an OSD will mitigate the increase to peak discharge for all possible storm events. Ensemble analysis is shown to provide improved results. However, it also falls short of providing any guarantee in the face of naturally occurring rainfall.

文摘A new organization and management mechanism with the local government as the main body was created during the post-disaster reconstruction of the "4. 20 " Lushan earthquake,in which the experiences and lessons were drawn from the "5. 12"Wenchuan earthquake. Correspondingly, the local government conducted an exploration of the organization and management mode in the field of planning and construction. The effective experiences have been accumulated, including working out a full coverage planning,taking the leading part in the urban-rural planning,and exercising whole space control over the disaster area. An innovation management mode named as "Five Generals Pattern"was implemented in the construction projects. In view that the rural housing reconstruction was a weak link, a new approach to improving the construction management was investigated,by means of strengthening on-site supervision,establishing a technical platform,and bolstering public participation.
文摘Classification management is one of nature reserves management system in China. But state nature reserves and local administration nature reserves under the regulations are only the approval system and embody the concept of protection. Management pattern of nature reserves can be divided into nine types. There are big differences in the nine patterns in management foundation and coordination ability of management because different management pattern occupies different resources of administration,personnel,financial and law enforcement. By analyzing management pattern,thirty-eight indexes in thirteen categories were selected to evaluate the management effectiveness of national nature reserves subordinate to the State Forestry Administration (SFA) . Results show that the management effectiveness of national nature reserves is good as a whole,and the management effectiveness is direct proportional to administration level. Provincial administration has the higher efficiency than municipal and county administration. Direct administration by governments at all levels has the higher efficiency than departments' administration at the same level.
文摘Background: Fournier's gangrene is a rapidly spreading necrotizing gangrene affecting the perineum, Perianal and genital regions but remarkably sparing the testicles, bladder and rectum due to their separate blood supply which is directly from the aorta. The aim of this study is to share our experience with the management of 46 cases. Patients and method: We retrospectively analysed the medical records of 46 patients admitted with Fournier's gangrene between April 2005 and December 2011 in the urology unit of Aminu Kano Teaching Hospital. Data extracted from these include age, sex, hospital stay, premorbid diseases, mobility, mortality, laboratory investigations and treatments carried out. Results: Fourty six patients were admitted and managed for Fournier's gangrene during the study period. All the patients were male and mean age was 50 years (range 20 - 80 years). Five patients died (10.90%) mortality, 41 (89.10%) patients survived. The shortest hospital stay was 13 days and longest was 120 days. 45.7% of the patients had urethral stricture with watering can perineum as predisposing factor, 16 (34.80%) had diabetes mellitus, 7 (15.2%) had perineal injuries as the predisposing factors while 5 (10.90%) patients had uraemia and one patient (2.20%) each had bladder tumour and scrotal abscess as their predisposing factors, in 3 patients (6.50%) it was idiopathic. Only 34 (73.90%) patients had wound swab microscopy culture and sensitivity on admission. The culture grew Klebsiella spp. in 9 (26.50%), Staph aureus and E. coli in 5 (10.90%) of cases each, while Gram positive rod and Gram negative Cocci with 4 (11.80%) and 6 (17.60%) respectively. Conclusion: Fournier's gangrene which is a rapidly progressive, fulminant polymicrobial synergistic infection of the perineum and genitals, is now changing pattern. Extensive surgical debridement and broad spectrum intravenous antibiotics remain the mainstay of treatment.
文摘The traffic activity offifth generation(5G)networks demand for new energy management techniques that is dynamic deep and longer duration of sleep as compared to the fourth generation(4G)network technologies that demand always for varied control and data signalling based on control base station(CBS)and data base station(DBS).Hence,this paper discusses the energy management in wireless cellular networks using wide range of control for twice the reduction in energy conservation in non-standalone deployment of 5G network.As the new radio(NR)based 5G network is configured to transmit signal blocks for every 20 ms,the proposed algorithm implements withstanding capacity of on or off based energy switching,which in-turn operates in wide range control by carrying out reduced computational complexity.The proposed Wide range of control for base station in green cellular network using sleep mode for switch(WGCNS)algorithm toon and off the base station will work in heavy load with neighbouring base station.For reducing the overhead duration in air,heuristic versions of the algorithm are proposed at the base station.The algorithm operates based on the specification with suggested protocol-level to give best amount of energy savings.The proposed algorithm reduces 40%to 83%of residual energy based on the traffic pattern of the urban scenario.
