They can be grouped into 4 orthosequence sets, in which the maximum flooding surfaces lie in the sulcutus Zone (D12), perbonus Zone (D13), Middle and Upper varcus Zone (D22) and gigas Zone (D21) respectively. Four instant palaeogeographical reconstructions of South China have been made in the Emsian and Givetian. Devonian sea-level change rhythms of South China can be divided into 3 categories: the autorhythmic, the worldwide and regional allorhythmic, and the coupling-rhythmic. They developed respectively in the Famennian, Pragian, Eifelian, Lochkovian, Emsian, Givetian, Frasnian and the F / F (between the Frasnian and Famennian) event. The cause of the worldwide allorhythmic SLC of the Pragian and Eifelian under comparatively dry, warm and tranquil conditions may be related to the pulsating expanding and contracting of the oceanic basin volume or the earth volume pulsation, rather than the common glaciation and plate tectonism. The coupling-rhythmic SLC related to the F/ F event is a sensitive indicator of the interaction between terrestrial and extraterrestrial factors, and coordinated action among the earth-spheres.展开更多

CVD, including stroke and heart disease, takes about 267,000 women’s lives every year [1]. In the present study, a health risk assessment of a population of women residing in North-eastern Pennsylvania was conducted to provide an estimate of vulnerability to stroke on the basis of medical history, genetic predisposition, and other lifestyle factors. Using the Health Belief model of Rosenstock, Strecher, and Becker [2] and the stage model of Prochaska, Diflemente, and Norcross [3], a health promotion plan was developed to address the needs of that population. An evaluation of risks that can and cannot be modified is developed to help people understand the basic lifestyle changes that could be made to prevent CVD, which includes stroke. An action plan was developed to lower the risk of stroke among women based on their individual needs and to raise awareness throughout the United States. Individuals should take the essential precautions for their personal cases. This will substantially lower the risk of CVD, especially stroke, among women.展开更多

Design: A cross-cultural comparison. Setting: Japan, South Korea, and Austria. Subjects: Female university students from Japan (n = 276), Korea (n = 103), and Austria (n = 127). The survey comprised a questionnaire containing ten sections about eating behaviors (eating habits, regular meal times, and frequency of food intake) and eating attitudes. Results: Eating behaviors and attitudes differed significantly among the three cultures. Japanese students practiced healthier eating behaviors than did Korean and Austrian students, on the basis of their variety of food intake and regular consumption of three meals, but rated themselves lower on healthy eating behaviors. Austrian students tended to have more independent attitudes toward eating and food preparation (e.g., “I want to eat only my favorite dishes”) than Japanese or Korean students. Conclusions: Effects of cultural differences in psychological processes, such as self-cognition, emotion, motivation, and values, on self-assessment of eating behaviors is suggested.展开更多

This cross-sectional study has tried to examine HIV/AIDS-related stigma among Nepalese returnee male labor migrants. Migrant workers who have worked at least six months abroad were asked different questions related to sexual behavior, knowledge on HIV/AIDS & condom and HIV/AIDS-related stigma. Stigma was measured on a three-point rating scale as high, average and low stigma. About 58% of migrants had the view “I would rather not know if I have HIV” followed by “I don’t want to be friends with people living with HIV” (53.6% migrants) and “people with HIV are cursed” (35.5% migrants). High stigma was present among 15.5% of the total respondents with high proportion among those with higher age, lower education, rural residence, and no knowledge on Voluntary Counseling and Testing (VCT) service. About a quarter of respondents were of the view that migrants infected with HIV while abroad should not be allowed to return Nepal. Some level of stigma on HIV/AIDS exists among male labor migrants in Nepal. Interventions aiming at reducing stigma should consider the factors like migrants’ age, education, place of residence and knowledge on VCT services.展开更多

The more severe delirium is the worst the clinical outcomes of medical illness. Despite the obvious, not much has been documented on delirium severity and its associated factors among medical inpatients in low income countries including Nigeria. Objectives: This study was conducted to examine the severity of delirium among medical inpatients admitted through the Accident and Emergency unit of Jos University Teaching Hospital as well as to assess its associated Sociodemographic and Clinical characteristics. Method: This was a cross-sectional study that employed a consecutive sampling technique to select 290 eligible subjects from medical inpatients that presented to Accident and Emergency unit of Jos University Teaching Hospital. On admission, patients were assessed for delirium using Confusion Assessment Method and severity of delirium was evaluated using Delirium Rating Scale-Revised-98. Results: Of the 105 delirious medical inpatients, 48 (45.7%) had severe delirium, 41 (39.1%) developed less severe delirium while 16 (15.2) presented with no severe delirium. Sociodemographic characteristics found to be significantly associated with less to more severe delirium include male gender (P = 0.001), nonprofessionals (P = 0.003), income range of N20,000 - N49,000 (P Conclusion: This study demonstrates that delirium is often associated with higher severity in Accident and Emergency unit admission and there are strongly associated clinical characteristics to watch out for in high risk medical inpatients.展开更多

Objectives: To determine the prevalence of dyspareunia and its effect on sexual life among gynaecology clinic attendees in Alex Ekwueme Federal University Teaching Hospital, Abakaliki. Materials and Methods: A cross-sectional study was conducted on consenting participants between 12th May 2016 and 25th July 2016. Anonymous self-administered questionnaires were used collection information on dyspareunia and its effect on sexual life at the Gynaecology clinic. The data was analyzed using Epiinfo version 7.1.5. Results: One hundred and four (104) women participated in this study. Most of the women studied were Igbos (95.19%), and were mainly between the age ranges of 21 - 30 years (66.35%). Most of them were married (89.42%), and were also mainly of the Pentecostal denomination (40.78%). The mean age at coitarche was 20.6 ± 3.95 years. Prevalence of dyspareunia was 36% and only 16% sought medical help. The various responses to dyspareunia were avoidance of sex 11%, reduced frequency of intercourse 8%, less desire for sex 19%, while majority of women with dyspareunia tolerated it (62%). Conclusion: The prevalence of dyspareunia is high in our society afflicting young women in their reproductive years with associated enormous stress on their sexual life.展开更多

It reached epidemic proportions in Europe and North America during the 18th and 19th centuries. The incubation period is 2 - 6 weeks and the control has been complicated with emergence of HIV and drug-resistant TB. In 1993, World Health Organization (WHO) declared TB a global emergency. However, despite the concerted effort of National TB control programs, adoption and implementation of Stop TB strategy, TB has remained a major public health challenge with high mortality rate, especially in developing countries. Methodology: This is a descriptive study, evaluated using the positivist/quantitative approach. The study was conducted at FederalMedical Centre Umuahia, a tertiary specialist hospital with comprehensive TB/HIV treatment services. All the presumptive drug-resistant TB cases and symptomatic PLHIV were screened for HIV and their sputum specimens were tested for tuberculosis using the Gene xpert and the Ziehl- Neelsen technique for detecting Acid Fast bacilli. A pretested structured questionnaire was used tocollect the demographic data and other essential data from the presumptive TB and laboratory registers such as total number of TB presumptive cases registered HIV status, AFB status and rifampicin status within the study period. Result: A total of 493 presumptive TB cases were screened in the study, 49.9% were HIV positive while 50.05% were HIV negative. More so, 77.85% of thescreened cases were AFB negative and 22.15% were AFB positive. Moreover, 11% of the TB/HIV co-infected patients were rifampicin positive. Interestingly among the 493 cases screened with gene xpert machine, 3.6% were rifampicin positive. Furthermore, 3.6% of the HIV negative cases were rifampicin positive while 1.6% of the HIV positive cases were rifampicin positive. Discussion: The data depict lower rifampicin resistance among HIV positive cases than HIV negative cases. The implication for public health professionals is to intensify equitable and unbiased search for resistant TB cases among smear negative and positive cases.展开更多

Our conclusion is as follows: Significant strategic interaction exists among provincial governments regarding expenditures mainly owing to fiscal competition mechanism in China, and expenditures interaction has changed significantly since tax sharing system reform, which has had positive effects on regional economic growth. This conclusion has significant implications for the optimization of public functions, size and structure of local governments in China.展开更多

This study examines five factors： slope angle, slope aspect, lithology, peak ground acceleration （PGA）, and fault side （relative position on the seismogenic fault, i.e., hanging wall or footwall）, to determine how these factors control the co-seismic land- slide occurrence and whether one or more factors, acting alone or in concert, are involved in promoting or suppressing landslides. We performed a multi-factor statistical analysis using data from the 2008 Wenchuan earthquake. The results show that in the areas characterized by steep topography or where strong ground shaking occurred during the earthquake, there is a closer relation- ship between slope aspect and landslide number density （LND） than other areas. The relationship between lithology and LND values depends on PGA. In turn, the relationship between LND values and PGA is also influenced by lithology. In addition, the controlling effect of lithology on co-seismic landslides on the hanging wall of the seismogenic fault is greater than that on the footwall. Examining interactions among these factors can improve understanding of the mechanisms of co-seismic landslide occurrence.展开更多

文摘The 12 May 2008 Mw 7.9 Wenchuan, China earthquake triggered about 200,000 landslides, which were controlled by a number of factors. This study examines five factors： slope angle, slope aspect, lithology, peak ground acceleration （PGA）, and fault side （relative position on the seismogenic fault, i.e., hanging wall or footwall）, to determine how these factors control the co-seismic land- slide occurrence and whether one or more factors, acting alone or in concert, are involved in promoting or suppressing landslides. We performed a multi-factor statistical analysis using data from the 2008 Wenchuan earthquake. The results show that in the areas characterized by steep topography or where strong ground shaking occurred during the earthquake, there is a closer relation- ship between slope aspect and landslide number density （LND） than other areas. The relationship between lithology and LND values depends on PGA. In turn, the relationship between LND values and PGA is also influenced by lithology. In addition, the controlling effect of lithology on co-seismic landslides on the hanging wall of the seismogenic fault is greater than that on the footwall. Examining interactions among these factors can improve understanding of the mechanisms of co-seismic landslide occurrence.
