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.

The Case Study of the Assessment of Ground Water Quality and Acceptance in Residential Urban Suburbs in Bindura, Zimbabwe

The research centered on the groundwater quality parameters in five boreholes and three wells in residential urban areas of Zimbabwe. Ten runs of chemical analysis for water pH, EC （electrical conductivity）, water hardness were carried out weekly and averages were calculated for each at Bindura University laboratory. Iron concentrations analysis was done at the Tobacco Research Station. The results from boreholes and wells were compared to the WHO （World Health Organisation） drinking water acceptable standards to measure the deviations. It was found that the boreholes had hard waters （112 mg/L）, EC （425 s/m） and iron concentration （0.49 ppm） outside the WHO standards （〉 64 mg/L; 400 s/m; 0.3 ppm respectively）. In contrary the wells had only the water pH slightly outside the acceptable ranges （5.8）; other parameters were in the acceptable ranges （EC 379 s/m; water hardness 0.38 mg/L as CaCO3 and iron concentration 0.38 ppm）. The difference in chemical composition between the boreholes and wells caused the borehole water rejection in favor of well water. High iron concentrations and water hardness in boreholes were major contributors to the water rejection by the residents.

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 spaee for the local people to improve their living structure and meet their demands for reereational activities, and urban residential land, rural residential land, mining land and transportation land of 1107.60 ha, 120.27 ha, 162.48 ha, 100.91 ha, respeetively can satisfy the resident＇s eeonomie development and infrastructures; 4） the equilibrium among industrial actions, landscape accessibility and ecological conservation can be obtained by analyzing the possible impaets of human activities on landscape eeologieal proeess in open spaee of metropolitan suburbs in mountain areas.

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

LANDSCAPE PATTERN CHANGES IN WEST SUBURBS OF SHENYANG

Spatial pattern of landscape is a central issue in landscape ecology study. The main reason of landscape patten change owes to the external disturbance. In this article, retrospective sequential airphotoanalysis and statistical analysis of information on landscape development were used and two remarkable changes of landscape pattern in west Shenyang were identified: (a) one landscape element becomes a new matrix in place of the former one; (b) landscape proportions among several constiting elements changed significantly. This paper studied spatial pattern of the landscape using following quanta indices: (1) number and size of patches, (2) transition matrix of patches, (3) priority index of each kind of patch and (4) diversity and evenness indices of landscape.The results show that the landscape of west Shenyang has been more and more disturbed by human activities, so it becomes fragmentary throughout 30 years, and many blocky and island-like patches emerged.

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.

Shrinking and Super-Aging Suburbs in Japanese Metropolis

Japan＇s aging rate has exceeded 26%, ahead of any other country in the world. Aging is progressing rapidly in both rural and urban areas. Recently, super-aging in old suburbs is remarkable. Recently, Japanese old suburban housing estates are declining. They are facing several serious problems. Most serious problems are aging of residents and decreasing population, and these are caused by long-term dwelling. Because many Japanese think that ＂Japanese Dream＂ is occupancy of detached house in suburb. Japanese suburban residents tend to stay after child rearing. And another severe problem is the increasing vacant houses. In this study, the authors try to clarify the conditions of shrinking suburbs in Japanese cities and will introduce some activities for revitalization in suburbs. As for aging of suburban residents, in old housing estates, the first generation of migrants grew older and continued to live in their own house in suburban areas. Furthermore, their children grew up and moved out. These are caused by the failure of town planning, which supplied the same type of houses in short term. Furthermore, increases in vacant houses are seen throughout every old suburban housing estate, and it induces new uneasiness and social troubles and drop in housing price.

Dodging the Potholes： The Spatio-Distribution and Socio-Economic Impacts of Potholes in the Residential Areas of Gweru, Zimbabwe

Since the year 2000, the city of Gweru has had an unprecedented proliferation of unattended potholes on most of its roads. These potholes have caused discomfort to the motoring public, caused death to others and damaged vehicles. This paper presents the results of a study that sought to establish the spatial distribution of potholes and determine their socio-economic impacts in Gweru＇s residential areas. Pothole location and dimensions were measured in the field whilst interviews and questionnaires were administered to vehicle owners, motor mechanic experts, drivers and the travelling public to determine their socio-economic and mechanical impacts. Stratified, convenience and purposive sampling methods were used in the selection of study streets and respondents to questionnaires and interviews. Results revealed that potholes are more concentrated in high density residential areas compared to low density areas. This is primarily due to the substandard construction of roads done in high density residential areas. Other causes of pothole formation identified during this study are poor drainage on the roads, rainfall impact, advanced age of roads, poor or lack of maintenance, type and volume of traffic as well as the effect of tree-root prying on paved surfaces. It is recommended that Gweru City Council enters into partnerships in road construction. The city should also establish fundraising projects to augment its budget. This would help ease problems of service delivery including road maintenance. Signposts can be erected to warn drivers about these hazards in the most affected streets and suburbs. It is also important that council set aside a toll-free telephone line link with road users so that areas where new potholes have been detected are quickly reported and attended to. This will not only save lives but also reduce road maintenance costs and vehicle damage.
