Prevalence and Risk Factors of Vaginal Trichomoniasis in Women: Study at the University Hospital of Pikine in the Suburbs of Dakar, Senegal

Introduction: This study aimed to investigate the epidemiology of genital trichomoniasis in Senegal. It sought to determine the prevalence and risk factors associated with this condition in Senegal. Methodology: The study took place at the university hospital of Pikine in the suburbs of Dakar. For each of the women recruited, socio-demographic data, clinical examination data and the results of direct examination of the vaginal sample were collected in a questionnaire designed for this purpose. Results: A total of 312 women with a mean age of 31.13 (±8.41) years were recruited in this study. The majority of these women (59.94%;95% CI = 54.25 - 65.38), were seen for an infectious diseases assessment. Leucorrhea (58.33%;95% CI = 52.63 - 63.83) and genital discharge on vaginal touch (99.36%;95% CI = 97.45 - 99.89) were the predominant signs on clinical examination. The overall prevalence of vaginal trichomoniasis after direct examination of the specimens was 1.28% (95% CI = 0.41 - 3.47). Only the distribution of this prevalence by occupation was statistically significant (p = 0.0004). Conclusion: The low prevalence of genital trichomoniasis in women and the risk factors associated with it found in this study, which took place about ten years ago, should prompt an update of the data to better define the problem in Senegal.

Life satisfaction approach to farmers' compensation for land acquisition:empirical study from the suburbs of Wuhan City

Farmers' compensation for land acquisition is not only critical to increasing their income and to playing a pivotal role in maintaining rural stability,but also to the promotion of sustainable land use.Based on analysis of Chinese land acquisition policy under the Land Management Law,which provides principles or guidelines for determining compensation according to agricultural land use in regard to farmers' previous quality of life,the Life Satisfaction Approach is introduced in this article to evaluate farmers' compensation for land acquisition.Employing data from a questionnaire survey on 346 farming households in Wuhan Suburbs,this article examined the influence of farmland on farmers' life satisfaction and evaluated the level of compensation for land acquisition.Results show that farmland has a significantly positive impact on life satisfaction,which fell by 0.033 on a five-point scale following a reduction farmland by of 1 mu.Respondents were willing to accept approximately RMB 3066.44 annual household income for the loss of 1 mu farmland;the level of compensation after discounting by 6.2%is RMB 750,000 per hectare.It was found in a further comparative study that the level of farmers' compensation for land acquisition is decidedly low,and it was also shown that their compensation standards,as well as the actual compensation,could be substantially improved by expanding economic compensation to non-economic compensation to embody farmland multifunction in terms of production and non-production against farmers' previous quality of life.This article proposes a compensation model that enriches the content of land acquisition compensation,extends the current literature on measuring compensation,and provides economic theory bases for increasing compensation standards and improving policies related to land acquisition.We consider that if this compensation model is applied,it could raise the cost of land acquisition and improve usage of land,reduce the speed of rural-urban land conversion,and improve farmers' well-being.

A STUDY ON LOCATION OF TOWNSHIP INDUSTRY IN SHANGHAI SUBURBS

The township industry in Shanghai suburbs has undergone a rapid development in the past few years. Aimed at studying the spatial law of the township industry in Shanghai suburbs, three kinds of indexes including distribution density, economic benefit, and regional structure are selected and analysed using correlation analysis method. There are 12 indexes in total. It is found that the locational variation of the township industry in Shanghai suburbs conforms to the following distribution equation:y=ae-bx (x】 5)The above equation has been more and more conforming to the real distribution of the township industry. It is obvious that decreasing trend from inner suburban districts to outer suburban districts is an important character of the locational variation of the township industry of Shanghai suburbs. The fact is closely related with the radiation intensity of the urban economy and the locational superiority for the development of township industry. The regional strategies of the township industry of

GIS- and RS-based Analysis of Suburban Landscape Layout in Haikou City

Landsat TM/ETM+ and Alos remote sensing data of the study area in 1991, 2001 and 2010 were interpreted by using object-oriented RS image extraction technology, landscape ecology theories were applied as well as GIS and FRAGSTATS4.1 to choose reasonable landscape indexes for studying temporal-spatial changes of suburban landscape layouts of Haikou City, exploring spatial features and change tendency of rural landscapes. According to the results, tropical garden landscapes have taken a dominant status in the last 2 decades; tropical farmland landscapes have had the most complicate shapes; tropical open forest landscapes have been most influenced by human interventions but had the best connectivity and high degree of concentration; tropical settlement landscapes and tropical meadow landscapes have been widely scattered with poor connectivity; landscape connectivity has been well maintained; contagion index has changed slightly, landscape equilibrium has been stable; landscape diversity has been maintained, all landscape types have been evenly distributed, landscape fragmentation has increased, and landscape heterogeneity has grown.

Distribution Characteristics of Pb and Its Ecological Risk in Different Farmland Soils of Changchun Suburb

Pb in the farmland surface soil of Changchun suburb was taken as the main research object. The field research and laboratory analysis were used to investigate Pb content, spatial distribution characteristics and its ecological risk in different farmland soils. The results showed that Pb content was during 18.85 - 41.34 mg/kg in farmland soil of Changchun suburb, and was higher than the background value of Jilin Province at 90% of the sampling sites. The spatial distribution of Pb content in farmland soil had obvious geographical features, and Pb content in southwest and northeast soils was higher. The high-content areas were relatively concentrated, and Pb content gradually reduced from the high-content island- shape center to its surrounding. The soil Pb contents in paddy field, dry field and vegetable field had insignificant difference with the background value, indicating that Pb accumulations in dry field, paddy field and vegetable field were not significant. The order of Pb content in different land use types was showed as follows： vegetable field 〉 dry field 〉 paddy field. Pb pollution of all samples belonged to light pollution. The average potential ecological risk of soil Pb in different land use types presented the following order： vegetable field 〉 dry field 〉 paddy field.

Two NGO-Run Youth-Centers in Multicultural, Socially Deprived Suburbs in Sweden—Who Are the Participants?

Objective: Leisure-time is an important part of young people’s lives. One way to reduce social differences in health is to improve adolescents’ living conditions, for example by enhancing the quality of after-school activities. Multicultural, socially deprived suburbs have less youth participation in organized leisure-time activities. This study explores who the participants are at two NGO-run youth-centers in multicultural, socially deprived suburbs in Sweden and whether socio-demographic, health-related, and leisure-time factors affect the targeted participation. Methods: The study can be seen as an explanatory mixed-methods study where qualitative data help explain initial quantitative results. The included data are a survey with youth (n = 207), seven individual interviews with staff, and six focus-groups interviews with young people at two youth-centers in two different cities. Results and Conclusions: The participants in the youth-centers are Swedish born youths having foreign-born parents who live with both parents, often in crowded apartments with many siblings. Moreover they feel healthy, enjoy school and have good contact with their parents. It seems that strategies for recruiting youths to youth-centers have a large impact on who participates. One way to succeed in having a more equal gender and ethnicity distribution is to offer youth activities that are a natural step forward from children’s activities. The youth-centers’ proximity is also of importance for participation, in these types of neighborhoods.

Mountain Land Use Planning of Metropolitan Suburbs:the Case of the Jinyun Mountain and Its Surrounding area,Chongqing,China

Open space of metropolitan suburbs in mountain region,has been increasingly becoming the coupling mosaic structure of industrial actions and landscape behaviors. However,the local governments,when making land use planning,often aim at economic development,and rarely refer to the coordination of compatibilities and conflicts between industrial actions and landscape behaviors in the mosaic structure. In this study land use in the Jinyun Mountain and its surrounding area,Chongqing is adjusted by gray multi-objective programming approach and local-level decision-making process to cope with conflicts between objectives for human welfare and objectives for landscape conservation. The results indicate that: 1) the compatibilities and conflicts among different behavior characters and different landscape types result in the compatibilities of landscape to human behavior;2) a land use planning in the study area is produced based on the sustainable land use and social-eco development,which pays more attention to the resources and environment constraints and economic objectives,and follows the distribution law of rare resources;3) in the study area,cultivated land of 1,207.27 ha can meet the demands for food and byproducts by the residents there,orchard land and forestland of 632.55 ha,2,276.61 ha,respectively can provide enough space for the local people to improve their living structure and meet their demands for recreational activities,and urban residential land,rural residential land,mining land and transportation land of 1,107.60 ha,120.27 ha,162.48 ha,100.91 ha,respectively can satisfy the resident’s economic development and infrastructures;4) the equilibrium among industrial actions,landscape accessibility and ecological conservation can be obtained by analyzing the possible impacts of human activities on landscape ecological process in open space of metropolitan suburbs in mountain areas.

A model of suitability evaluation of tourism development for the suburban mining wasteland and its empirical research

The model of suitability evaluation of tourism development for suburban mining wasteland was established in Fengquan District of Xinxiang City, with measurable methods to provide the basis for its tourism development and landscape planning. The construction and evaluation of the model was conducted with AHP method from the follow-ing four aspects: ecological importance, landscape importance, economic importance and social importance, vali-dated with the case. In the established evaluation system, weight values of six indexes are higher than 0.05, among which the weight of industrial characteristics is the highest, and the weight of area, pollution conditions, air quality conditions, landscape diversity and topography were also higher. There are still seven indicators with weight values of higher than 0.02, including land price, transportation accessibility, geological conditions, water conditions, finan-cial security, distance to cities and similar competition. Weight values of five indexes are lower than 0.02, including government function, vegetation conditions, soil conditions, urban economic level and major tourism environment. We have tried to set a weighting set by AHP to avoid the shortcomings in ordinary weighting process, to perform the tourism evaluation with a maturely-developed method and solve the multi-indicator evaluation problems which in-volve the fuzziness and variability of scaling effectively. Our calculating method is a simple, reasonable, quantitative and feasible one, with general signif icance to non-structuralized project as development of wasteland.
