Childhood Diarrheal Diseases and Associated Factors in the Rural Community of Dejen District, Northwest Ethiopia
Full text linkDiarrheal diseases are among the three most important causes of morbidity, and mortality in low income countries including Ethiopia. Lack of sanitation facilities is a serious health risk and obliges people to practice open defecation, thereby increasing the risk of disease transmission. These problems are clear at Dejen district where childhood diarrheal disease is the top cause of morbidity among under five children. The aim of this study was to assess prevalence of childhood diarrheal diseases and associated factors in the rural community of Dejen district, northwest Ethiopia, 2014. In this paper; a community-based cross-sectional study was conducted. Five of the 21 rural kebeles in the district was selected randomly, finally 710 households were chosen by systematic random sampling using existing list of all households as a sampling frame. Data was collected using pre-tested WHO core questionnaire that was designed to explore factors related to diarrhea. Data enter and analysis was carried out using SPSS version 20. The level of association was dealt using confidence interval and odds ratio.This study conducted among 710 participants with response rate of 96.4% shows that, the prevalence of diarrhea was 23.8%. Tube well water source (AOR: 2.59,95% CI (169,3.95)), throwing away disposal of feces (AOR: 1.58,95% CI (1.10,2.26)), mother’s used hand washing with practice only water (AOR: 1.61,95% CI (1.04,2.84)) and having not supplemented with vitamin A (AOR: 1.92,95% CI(1.35,2.74)) were significantly associated with diarrhea. the prevalence of childhood diarrhea is high at Dejen district. Tube well source of water, throwing away disposal of feces, poor hand washing practice of the mother and lack of vitamin A supplementation were significantly associated with childhood diarrheal disease. The District and Zonal water office should increasing access of piped water in rural areas. The District and Zonal health office should improve awareness of the community on hand washing practice and on proper utilization of latrine to dispose excreta should be given a concern and Vitamin Supplementation to every child in the district should be strengthened.
Challenges in the Teaching and Learning of Concord in the Use of English Language
Full text linkThe study analyzed the concord errors in the written composition of J.S.S.III pupils in some selected secondary schools in Abeokuta Central Local Government, Ogun State. It specifically presents the descriptive analysis of socio- demographic characteristics of respondents; investigated the types of concord errors made by J.S.S III pupils in selected secondary schools in Abeokuta Central Local Government, Ogun State; found out the common errors the students make in their essays; and identified the various problems the pupils often encounter in the use of concord. The study utilized both primary and secondary sources of data collection. A simple random sampling technique was used in obtaining information from respondents. The instrument used is questionnaire. A total of seventy two (72) copies of questionnaire were administered on the respondents who were randomly drawn from the population from which sixty two (62) copies were retrieved. A total of sixty (60) scripts were analyzed to identify the problems in writing grammatically correct subject-verb agreement by the students. Secondary data were also sourced from text books, journals, research projects, Newspaper and Magazine and website publications. Data collected were analyzed using descriptive statistical method of analysis such as tabulation and percentages. The study revealed that majority in JSS III Pupils in Abeokuta Central Local Government, Ogun State has problems in applying the rules of concord. Most of the errors committed were under subject verb concord of number and person. The study concluded that teachers should attempt in-service training so that students can write error free essays and students should be given an eloquent and essential English teaching curriculum.
Gamo Society Vernacular House Typologies and Their Science, Southern Ethiopia
Full text linkThe main purpose in this study is to identifying house typology & their science in Gamo society, southern Ethiopia. It provides facts about the vernacular houses of the society. Types are identified without looking in to architectural detail, ornament, building materials and construction techniques. In determining house typologies, generally only the core or main part of the house is considered; small side wings, rear service (or extensions) later additions, and attached outbuildings usually are not taken in to account. A case study which is supplemented with a qualitative research method was conducted from Nov./2012-Jan./2013. The case study was done in one year by taking 57 sample vernacular house typologies from 42 Deres/communities/. Data were collected using qualitative methods, Capturing images, videos and as well as observation. After clearing and checking for consistency data was grouped, edited, coded and analyzed.The result shows in Gamo society three major vernacular house typologies; Waje, Kara and Yara, were identified based on their shape, function, method of construction and construction material they used. And the result of this study showed that Gamo society is inter-related with their vernacular houses.
Students’ Perception Towards the use of Traditional Medicine for the Treatment of Mental Disorders: The Case of Arba Minch University
Full text linkThe purpose of this study was to examine university students’ perception towards the use of traditional medicines (TMs) in the treatment of mental disorders. Students-based cross sectional type of research design was employed to conduct this study. The findings of this study revealed that most of the study participant’s 197(63.5%) preferred traditional medicines before joining to the Arba Minch University for the Treatment of mental disorders. But, 113(36.5%) of the respondents preferred modern medicines. The study also revealed that students expressed positive perception towards the use of traditional medicines in the treatment of mental disorders. And, there was statistically significant difference in perception scores due to college (F (3,298) =3.197, p=0.024 and year levels (F (2, 298) =3.466, p=.032), Ethnic-background and socio-economic status interaction effect (F (7,295) =2.403, p<0.05) in perception towards the use of Traditional Medicines (TMs) in the treatment of mental disorders. This study was concluded family was the main source of information about TMs. From this, the researcher believed families were influential in their decision to use TMs and played a role in providing assistance with uncertainty around decision-making and telling about a success of treatment for a problem
Engineering geological and geotechnical appraisal of Northern Mekelle town, Tigray, Northern Ethiopia
Full text linkAs population number grows, the demand of constructing buildings for residential, commercial, industrial, and other purposes also increases. Mekelle town is presently rapidly and geometrically expanding towards all directions, and several civil engineering structures such as single to multi-storey buildings, roads, bridges, etc. are under construction. The main research aim is to characterize the engineering geological and geotechnical properties of soils and rocks, and develop detailed multi-purpose engineering geological map at a detail scale. Engineering geological and geotechnical characterization of soils and rocks are based on their index and engineering properties, and their classification is according to the standard proposed by Unified Soil Classification System (USCS) and International association of Engineering Geologists (IAEG (1981). According to USCS; soils are classified into: fat clay type; inorganic silt, elastic silt and (silty of clayey fine sand with slight plasticity) of silt soil types; lean sandy clay, inorganic silts, elastic sandy silt of sandy clay/ silt type; and clayey/ silty sand soil types. According to IAEG (1981); soils are classified into: clay of intermediate and high plasticity; silt of intermediate, high and very high plasticity; SAND clayey of intermediate plasticity, SAND silt of high plasticity; and CLAYEY sand of intermediate, high plasticity and SILT sand of intermediate plasticity). Classification of rock masses is based on their strength, degree of weathering and joint characteristics; classified into three major engineering geological subunits: rocks with low mass strength, rocks with medium mass strength and rocks with high mass strength
