Methods: The clinical data of 43 patients with synchronous primary cancer of endometrium and ovary were retrospectively reviewed. The survival was calculated by Kaplan-Meier method and compared using the log-rank test. Results: The median age of the patients at diagnosis was 49 years (range, 28-73 years). The most common symptoms were abnormal vaginal bleeding (69.8%) and abdominal or pelvic pain (44.2%). Pelvic masses were found in 39.5% of the patients and enlarged corpus in 27.9% at physic examination, while pelvic masses were found in 67.4% of the 43 patients (29 cases) and thickening or abnormal endometrium in 23.3% (10 cases) during ultrasound examination. Of 25 patients examined by CT/MRI, pelvic masses were found in 13 cases and enlarged uterus in 11 cases. All 15 patients who underwent endometrial biopsies were proven to have endometrioid carcinomas. Serum CA125 level was found to be elevated in 22 of the 34 examined cases (64.7%) with median value 500 U/mL (range, 39-3439 U/mL). FIGO stages of endometrial carcinomas: IA 18 cases, IB 20 cases, IC 2 cases, and ⅡA 3 cases; Stages of ovarian carcinomas: IA 19 case, IB 4 cases, IC 7 cases, Ⅱ 4 cases, and ⅢC 9 cases. Twenty-four patients (55.8%) were in stage I both endometrial and ovarian carcinomas. Thirty-one patients underwent total hysterectomy plus bilateral salpingo-oophorectomy with omentectomy and appendectomy, meanwhile, 12 patients had pelvic lymph nodes dissection. Thirty-eight of the 43 patients (88.4%) had a pathologically proven endometrial adenocarcinomas. The predominant ovarian histologies were endometrioid or mixed tumors with endometrioid components (30/43, 69.8%). Postoperatively, 26 patients (60.5%) received adjuvant chemotherapy alone, 12 had chemotherapy plus radiotherapy, only one patients had radiation alone and the remaining 4 cases received no adjuvant treatment. The 3-year and 5-year survival rates of the group were 87.4% and 71.1% respectively. The 3-year and 5-year survival rates of patients with endometrioid carcinoma at both endometrial and ovarian were higher than that of those with non-endometrioid or mixed histologic subtypes (93.8%, 82% vs 79.7%, 69%). The 3-year and 5-year survival rates of patients with early stages disease were better than those of other patients (93.3%, 93.3% vs 69.7%, 36.7%). Recurrence developed in 15 patients (34.9%). It was showed by univariate analysis that lower CA125 level, early FIGO stage, and adjuvant chemotherapy plus radiotherapy significantly and positively affected the 5-year survival rate, while only early FIGO stage and chemotherapy plus radiotherapy were revealed by multivariate analysis as independent prognostic factors. Conclusion: Synchronous primary cancers of the endometdum and ovary were different from either the primary endometrial or ovarian cancer, while usually it can be detected in early stage with a good prognosis. The impact of the CA125 level on prognosis needs to be further studied. Surgery treatment alone may be enough for early stage patients. Chemotherapy plus radiotherapy may be necessary for advanced patients.展开更多

In the last decade we notice that banks pay a growing attention to their marketing services and in particular to the use of the latest technologies for their promotions. The use of the lnternet has influenced in the fact that customers now are closer to their banks, their number has increased, and of course through the Internet we have a more efficient exchange of products and services. A questionnaire was developed to help us understand the internet banking acceptance in Albania and other issues related to it. The questionnaire survey was conducted on 9 banks operating in Albania and from the evaluation of the collected data results that all banks that underwent questionnaire, have a separate marketing department. So marketing has an important role in the banking business. The importance of marketing rose by increased interbank competition in recent years. Crisis and economic and financial difficulties have shown that banks, which face these difficult periods, have been those which had not only a healthy bank policy, but also a strong commercial policy. These things depend on many factors, among which we can mention: the tradition, which has taught people to trust "their financial secrets" only to someone who exercises the profession of banker; the cultural and infrastructural level of development of the population, which gives approval and insures the continuousness of any discovery or development in various fields; the ability of this kind of banking to be successful, that is and remains the basis on which to establish a trustful cooperation relationship of any kind. Strong policies to e-marketing have targeted to increase the percentage of elements such as banking and credit granting. E-banking also consists of counseling online with a bank employee or financial advisor. This kind of service is not only effective for the client, who saves his time, but also more economical for the bank, which reduces its costs in human resources (an adviser to the window only deals with a client, while he can handle online more than two credit cases simultaneously, so we decrease the number of employees in general). With its low-cost structure, direct consumer marketing and innovative services, the internet is going to present a real challenge to traditional forms of banking. E-banking is seen from the banks as an opportunity to create competitive advantage over its competitors. It offers a great deal of advantages both to the banks and to the customers. Clients are becoming more and more demanding and they are expecting even higher levels of service from their banks.展开更多

Thousands and even millions of the people have been using Blog, Facebook, MySpace, Twitter, and others as a communication medium. Many of them are mobile connected and have made it a daily practices. Interestingly, all these changes are not followed by Onmi International Hospital which it ultimately in 2009 led to the crisis. This crisis was beginning from the customer, Prita Mulyasari, who felt disappointed at the hospital service, and wrote an e-mail to her friend. Suddenly, in a short time the e-mail was disseminated widely on the Internet and produced a lot of support and public humiliation to the Omni International Hospital. This paper aims at explaining the cybcr crisis experienced by Omni International Hospital and how to overcome the problem at corporate level.展开更多

The EFO can unify those optical operators in two-mode case. Various decompositions of EFO into the exponential canonical operators are obtained. The entangled state representation is useful in the research.展开更多

Thus, threats are unavoidable to banks if they fail to identify consequences and vulnerabilities accompanying e-banking practices. The usage rate of e-banking in a top international commercial bank in Malaysia is rather diminutive compare to its other bases in countries like Singapore, China and India. Interestingly, it is on decreasing mode year by year. This study aimed to offer a good set of information of the factors influencing low usage and possibilities to suggest ways to increase the usage among the bank customers. In this study, a comprehensive survey data gathering were used to collect and analyze the respondents and results indicate that ease of use is the most significant contributor to the low usage. 204 valid feedbacks were obtained from the SCM bank's customers, with the research indicating that e-banking still has a gap to fill between customers, the bank and the e-system in maximizing the desire of existing clients to go over the net.展开更多

Local traditional varieties that are largely taken care of and nurtured by farmers' seed system have also been excluded from the formal seed system. Nowadays, however, it is quite common to see locally-sourced vegetables on supermarket shelves, while an increasing number of consumers visit farmers' market and become aware of local traditional vegetables available only through such channels. It is in this context that many local governments, public agricultural experimental stations and even private seed companies are becoming interested in the use and management of local traditional varieties of vegetables in Japan. The objective of this paper is to elucidate some characteristics of and factors behind the condition, potentiality and limitations of farmers' seed systems vis-a-vis the expected role of public experimental stations and locally-based seed companies, especially when it comes to the use and management of local traditional vegetables and their genetic resources in Japan. This paper is based on our case studies, in which we conducted in some interviews with relevant local actors in addition to literature and statistical surveys.展开更多

The environmentalists across the globe have however expressed the concern on the use of GM crops as they feel that they would cause environmental damage and they are not safe for human consumption. In the meantime, the Genetic Engineering Approval Committee (the regulatory body for GM crops in India) evaluated the development process of Bt brinjal (eggplant) and has given its approval for commercial cultivation. This further aggravated the GM controversy; while the farmers are interested in cultivating Bt brinjal, the activists against GM crops have been protesting against the introduction of these hybrids stating that adequate tests have not been done to check on the safety of Bt brinjal. This controversy prompted the Minister of Environment of India Government to hold public consultations across India to access the views of the stakeholders. Based on the public consultations, the minister "put on hold the commercial introduction of Bt brinjal" on February 9, 2010. This paper analyses the view points of stakeholders collected at the public consultation held at Hyderabad on January 31, 2010. The analysis shows that the stakeholders develop different orientation based on the "stage of need hierarchy they are in" and the attributes they use to evaluate the outcome. The paper concludes that the views of the activist groups based on their limited understanding could get the introduction of Bt brinjal stalled as the companies failed in public communication and education. Policy implications are drawn for government consideration.展开更多

It integrates the case-based reasoning (CBR) with adaptive par- ticle swarm optimization (PSO). The nmnber of nearest neighbors and the weighted features vector are optimized online using the adaptive PSO to improve the prediction accuracy of CBR. The adaptive inertia weight and mutation operation are used to overcome the premature convergence of the PSO. The proposed method is validated a compared with the basic weighted CBR. The results show that the proposed model has higher prediction accuracy and better performance than the basic CBR model.展开更多

II also can provide a method to verify relative reliability of data from single satellite measurement. This pa- per presents a case study of energetic particles data cross-calibration between FY-3B and NOAA-17. A generally good agree- ment is acquired in the flux values and distribution trend of 2.5-6.9 MeV protons and 0.3-1.1 MeV electrons between FY-3B and NOAA-17 satellites. It suggests that the data observed by FY-3B is properly cross-calibrated. We can also confirm that energetic particles data observed by FY-3B satellite is available.展开更多

It is generally seen in patients who are immunocompromised. Only 15 cases have been reported till now, with only one case series of 6 patients, We report a case of septic arthritis of AC joint in an immunocompetent child. A 9 years old girl presented with history of pain in left shoulder for 4 days associated with fever, No history suggestive of any immunocompromised state was complained. On local examination, a swelling of around 3 cm in diameter was found over left AC joint region with raised local temperature, tenderness on palpation and positive response in fluctuation test. Total leukocyte count was 18.7 - 109/L with 80% of neutrophils. Erythrocyte sedimentation rate (ESR) was 28 mm/1 h. C-reactive protein (CRP) was 12 mg/L. X-ray showed enlarged left AC joint space. Ultrasound revealed hypoechoic collection in the AC joint and the surrounding area. The aspirate was thick and purulent in nature, revealing Gram positive cocci at staining. Arthrotomy and thorough lavage of AC joint was done. Culture of the aspirate showed Methicillin Resistant Staphylococcus Aureus (MRSA) after 48 hours that was sensitive to amikacin, gentamicin, erythromycin and teicoplanin. Patient was symptom-free at 2 months of follow-up with no signs of osteomyelitis on the radiographs. Thus this is the first case of AC joint septic arthritis in healthy individual. Being proximal to the shoulder joint, AC joint septic arthritis can be confused with the shoulder joint septic arthritis. Thus, high index of suspicion is required for accurate diagnosis.展开更多

文摘The sub-pixel impervious surface percentage(SPIS) is the fraction of impervious surface area in one pixel,and it is an important indicator of urbanization.Using remote sensing data,the spatial distribution of SPIS values over large areas can be extracted,and these data are significant for studies of urban climate,environment and hydrology.To develop a stabilized,multi-temporal SPIS estimation method suitable for typical temperate semi-arid climate zones with distinct seasons,an optimal model for estimating SPIS values within Beijing Municipality was built that is based on the classification and regression tree(CART) algorithm.First,models with different input variables for SPIS estimation were built by integrating multi-source remote sensing data with other auxiliary data.The optimal model was selected through the analysis and comparison of the assessed accuracy of these models.Subsequently,multi-temporal SPIS mapping was carried out based on the optimal model.The results are as follows:1) multi-seasonal images and nighttime light(NTL) data are the optimal input variables for SPIS estimation within Beijing Municipality,where the intra-annual variability in vegetation is distinct.The different spectral characteristics in the cultivated land caused by the different farming characteristics and vegetation phenology can be detected by the multi-seasonal images effectively.NLT data can effectively reduce the misestimation caused by the spectral similarity between bare land and impervious surfaces.After testing,the SPIS modeling correlation coefficient(r) is approximately 0.86,the average error(AE) is approximately 12.8%,and the relative error(RE) is approximately 0.39.2) The SPIS results have been divided into areas with high-density impervious cover(70%–100%),medium-density impervious cover(40%–70%),low-density impervious cover(10%–40%) and natural cover(0%–10%).The SPIS model performed better in estimating values for high-density urban areas than other categories.3) Multi-temporal SPIS mapping(1991–2016) was conducted based on the optimized SPIS results for 2005.After testing,AE ranges from 12.7% to 15.2%,RE ranges from 0.39 to 0.46,and r ranges from 0.81 to 0.86.It is demonstrated that the proposed approach for estimating sub-pixel level impervious surface by integrating the CART algorithm and multi-source remote sensing data is feasible and suitable for multi-temporal SPIS mapping of areas with distinct intra-annual variability in vegetation.

文摘Based on the entangled Fresnel operator (EFO) proposed in [Commun. Theor. Phys. 46 (2006) 559], the optical operator method studied by the IWOP technique (Ma et al., Commun. Theor. Phys. 49 (2008) 1295) is extended to the two-mode case, which gives the decomposition of the entangled Fresnel operator, corresponding to the decomposition of ray transfer matrix [A, B, C, D]. The EFO can unify those optical operators in two-mode case. Various decompositions of EFO into the exponential canonical operators are obtained. The entangled state representation is useful in the research.

In this study, a comprehensive survey data gathering were used to collect and analyze the respondents and results indicate that ease of use is the most significant contributor to the low usage. 204 valid feedbacks were obtained from the SCM bank's customers, with the research indicating that e-banking still has a gap to fill between customers, the bank and the e-system in maximizing the desire of existing clients to go over the net.
文摘This purpose of this article is to provide an overview of the research situation and the development model of the E-commerce finance. This article takes the cross-border cooperation in finance between banks and E-commerce companies. This paper introduces three development models of E-commerce finance. Banks set up their own E-commerce platform. The banks take advantage of E-commerce platform. The E-commerce companies run financial business. The theoretical findings reported in this paper pave the way for embarking on the promising and relevant future research.
文摘Nearly all countries have seed organisations and private seed companies, laws and technical regulations to govern their while the role of the farmers' seed system has formal seed system, run by formal public been marginalised especially in developed countries. Local traditional varieties that are largely taken care of and nurtured by farmers' seed system have also been excluded from the formal seed system. Nowadays, however, it is quite common to see locally-sourced vegetables on supermarket shelves, while an increasing number of consumers visit farmers' market and become aware of local traditional vegetables available only through such channels. It is in this context that many local governments, public agricultural experimental stations and even private seed companies are becoming interested in the use and management of local traditional varieties of vegetables in Japan. The objective of this paper is to elucidate some characteristics of and factors behind the condition, potentiality and limitations of farmers' seed systems vis-a-vis the expected role of public experimental stations and locally-based seed companies, especially when it comes to the use and management of local traditional vegetables and their genetic resources in Japan. This paper is based on our case studies, in which we conducted in some interviews with relevant local actors in addition to literature and statistical surveys.

文摘Eco-geographic regional system is formed by division or combination of natural features based on geographic relativity and comparison of major ecosystem factors(including biological and non-biological) and geographic zonality.In previous studies, soil types were often taken as a basis for soil regionalization.However, the quantitative characteristics of soil indicators are fitter than the qualitative ones of soil types for modern regionalization researches.Based on the second China's national soil survey data and the provincial soil resource information, by principal analysis and discriminant analysis, this paper discusses the appropriate soil indicators as the complement of eco-geographic region indicator systems and the relationships between these soil indicators and soil types in regionalization.The results show that five indicators are used in eco-geographic zonality in mid-temperate zone of eastern China which are organic matter content, cation exchange capacity, pH, clay content and bulk density in topsoils.With a regression-kriging approach, the maps of soil indicators in mid-temperate zone of eastern China are compiled with a resolution of 1 km in every grid and the indicative meanings of these soil indicators are discussed.By cluster analysis it is proved that these soil indicators are better than the soil types and soil regionalization in delineating eco-geographic regions.
文摘Bt cotton a genetically modified (GM) crop has provided higher yields and profits for the farmers in India since its introduction in 2002. The environmentalists across the globe have however expressed the concern on the use of GM crops as they feel that they would cause environmental damage and they are not safe for human consumption. In the meantime, the Genetic Engineering Approval Committee (the regulatory body for GM crops in India) evaluated the development process of Bt brinjal (eggplant) and has given its approval for commercial cultivation. This further aggravated the GM controversy; while the farmers are interested in cultivating Bt brinjal, the activists against GM crops have been protesting against the introduction of these hybrids stating that adequate tests have not been done to check on the safety of Bt brinjal. This controversy prompted the Minister of Environment of India Government to hold public consultations across India to access the views of the stakeholders. Based on the public consultations, the minister "put on hold the commercial introduction of Bt brinjal" on February 9, 2010. This paper analyses the view points of stakeholders collected at the public consultation held at Hyderabad on January 31, 2010. The analysis shows that the stakeholders develop different orientation based on the "stage of need hierarchy they are in" and the attributes they use to evaluate the outcome. The paper concludes that the views of the activist groups based on their limited understanding could get the introduction of Bt brinjal stalled as the companies failed in public communication and education. Policy implications are drawn for government consideration.

文摘To effectively predict the permeability index of smelting process in the imperial smelting furnace, an intelligent prediction model is proposed. It integrates the case-based reasoning (CBR) with adaptive par- ticle swarm optimization (PSO). The nmnber of nearest neighbors and the weighted features vector are optimized online using the adaptive PSO to improve the prediction accuracy of CBR. The adaptive inertia weight and mutation operation are used to overcome the premature convergence of the PSO. The proposed method is validated a compared with the basic weighted CBR. The results show that the proposed model has higher prediction accuracy and better performance than the basic CBR model.
文摘This is a case report with discussion of the maternal-fetal outcome of pregnant women with uncorrected transposition of the great arteries (TGA) associated with pulmonary arterial hypertension and a large ventricular septal defect. This case draws attention to the severity of the pathology and maternal symptoms prior to gestation, and how an adequate clinical management of both obstetrics and cardiology can provide a favorable outcome for mother and fetus.

文摘Cross-calibration of high energetic particle data is a primary requirement for the availability of multi-instrument, multi-spacecraft data. II also can provide a method to verify relative reliability of data from single satellite measurement. This pa- per presents a case study of energetic particles data cross-calibration between FY-3B and NOAA-17. A generally good agree- ment is acquired in the flux values and distribution trend of 2.5-6.9 MeV protons and 0.3-1.1 MeV electrons between FY-3B and NOAA-17 satellites. It suggests that the data observed by FY-3B is properly cross-calibrated. We can also confirm that energetic particles data observed by FY-3B satellite is available.
文摘Septic arthritis of acromioclavicular (AC) joint is a rare entity. It is generally seen in patients who are immunocompromised. Only 15 cases have been reported till now, with only one case series of 6 patients, We report a case of septic arthritis of AC joint in an immunocompetent child. A 9 years old girl presented with history of pain in left shoulder for 4 days associated with fever, No history suggestive of any immunocompromised state was complained. On local examination, a swelling of around 3 cm in diameter was found over left AC joint region with raised local temperature, tenderness on palpation and positive response in fluctuation test. Total leukocyte count was 18.7 - 109/L with 80% of neutrophils. Erythrocyte sedimentation rate (ESR) was 28 mm/1 h. C-reactive protein (CRP) was 12 mg/L. X-ray showed enlarged left AC joint space. Ultrasound revealed hypoechoic collection in the AC joint and the surrounding area. The aspirate was thick and purulent in nature, revealing Gram positive cocci at staining. Arthrotomy and thorough lavage of AC joint was done. Culture of the aspirate showed Methicillin Resistant Staphylococcus Aureus (MRSA) after 48 hours that was sensitive to amikacin, gentamicin, erythromycin and teicoplanin. Patient was symptom-free at 2 months of follow-up with no signs of osteomyelitis on the radiographs. Thus this is the first case of AC joint septic arthritis in healthy individual. Being proximal to the shoulder joint, AC joint septic arthritis can be confused with the shoulder joint septic arthritis. Thus, high index of suspicion is required for accurate diagnosis.
