Abstract Krueng Raya waters is an area that has a distribution of coral reef ecosystems. This study aims to determine the recruitment of hard corals after coral bleaching Krueng Raya waters, Aceh Besar District. This research was conducted in April 2017 in Krueng Raya, Aceh Besar. Data were collected at three observation stations using a systematic sampling method using a 1x1 m quadratic transect. Based on the study results, coral recruitment was obtained from eight families and 13 genera (Acropora, Cetenactis, Diploastrea, Favia, Favites, Galaxea, Goniastrea, Helliopora, Leptastrea, Montastrea, Pavona, Pocillopora, and Porites). Where the most abundant coral genus found was from the genus Pocilopora and Porites (16 coloni/10m2). while the station with the highest colony abundance was at station 3 with 28 colonies/10m2.

Abstract Background Malaria is a public health problem mostly in African region. More malaria studies have been investigated for under five children while little information is known for persons aged five and above. We assessed the prevalence and factors associated with malaria among febrile patients aged from five years in Ngoma district. Method Cross-sectional study was conducted from November to December, 2018. Systematic sampling method was used for participant’s selection. Data collection questionnaires were completed after informed or assent forms were signed by the participants. Thick blood smears were collected and tested for malaria parasites by laboratory personnel. Data entry was done through Microsoft Excel while STATA Version 13.0 was used for analysis. Bivariate and multivariate logistic regression was computed to determine the association between dependent and independent variables at 95%CI, p < 0.05. Results Overall, 420 febrile patients aged from five years were recruited and 257(61.2%) were confirmed malaria positive. Malaria microscopic positive results were significantly associated with being Male (aOR=1.57,95%CI:1.01-2.46) and living in Mutenderi Sector (aOR=7, 95%CI:1.2-40.92) compared to living elsewhere in Ngoma district. However in reference to 5-14 years age group, being in the age group of 15-24 years (aOR= 0.34, 95%CI:0.12-0.94) and ≥35 years (aOR=0.29, 95%CI:0.11-0.79) were more likely protected from the infection. Conclusion Malaria parasitaemia was found high in febrile patients aged five and above in the study area thus its prevention and control measures should be taken into consideration in this aged group as well. Moreover, particular attention is needed to male, Mutenderi residents and those in the 5-14 age group as they are more likely to get the malaria infection. Key messages Malaria, aged from five ,febrile patients

Gastropods are one of the biota that live in association with mangrove habitat. This study aims to compare the species composition and structure of the gastropod community in different mangrove habitats. This research was conducted in Banyuurip Mangrove Center (BMC), Ujung Pangkah-Gresik during July-August 2020. Determination of the observation station purposively based on physical differences in mangrove habitat. Estimation of mangrove and gastrode density by systematic sampling method using belt transects. There were 12 mangrove species with the highest number of species in the coastal mangrove habitat, with the highest species composition and density of Avicennia marina. The highest mangrove density was found in coastal mangrove habitats for all criteria. The number of gastropods found were 2,171 specimens belonging to 15 species, 5 families and 5 orders. The highest number of species, families and orders in coastal mangrove habitat were 1,191 specimens, 11 species from 5 families and 5 orders, the lowest was in estuarine mangrove habitat as many as 980 specimens from 9 species, 2 families and 2 orders. Densities of gastropods differ between mangrove habitats, with the highest density in coastal mangrove habitats and the lowest in estuarine mangrove habitats. The composition and density of the highest gastropods species in the estuary mangrove habitat is Cassidula aurisfelis and in the coastal mangrove habitat is Pirenella cingulata. The importance of conservation and rehabilitation efforts for mangroves that have been degraded to support the gastropods associated in it.

This paper argues that for any community transformation to be achieved, cultural values and legal frameworks, which influence issues relating to land rights and food security, must form an integral part of any policy intervention efforts. We adopted feminism as both a methodological and an analytical framework. The dominant research paradigm was qualitative. The study sample was 184 people obtained using a systematic sampling method. Data collection was through focus groups and interviews. We challenge contemporary development initiatives, in terms of their intentions and sustainability. Finally, it is important that any development initiatives facilitate the participation and involvement of all genders.

Prevalence of bullying among school going adolescents was estimated to be high (approximately 37%) in Sri Lanka according to the Global School based student Health Survey. However, limited number of studies were carried out in Sri Lanka on bullying among adolescents, specifically about early adolescents in rural settings. In this study, we aimed to fill the research gap in local literature. The objectives of this study were a) to describe prevalence of bullying acts and different types of bullying in schools, and b) to describe common responses to bullying among early adolescents in Galenbindunuwewa educational zone in Sri Lanka. A cross sectional study was carried out in three schools in Galenbindunuwewa educational zone. A multi-stage sampling method incorporated simple random sampling and a systematic sampling method was used. Three hundred seventy-two students in grade 7, 8, 9 (12-15 years of age) participated in the study. A self-administered questionnaire was used to collect data. Statistical Package for Social Sciences (SPSS) version 21 was used for data analysis. Descriptive statistics were employed. Bullying acts were reported as prevalent among early adolescents in schools in Galenbindunuwewa educational zone. Calling mean names, pushing, and hitting, disturbing learning processes were the most prevent bullying acts. The most common response of the victims for bullying were tolerating it and walking away.

This study sought to examine the dominant frame in terms of ‘war’ and ‘peace’ in the coverage of the 2007/2008 post-election violence. At the time, Kenya had eight daily and over 10 weekly newspapers (Mbeke, 2008). The Daily Nation and The Standard were selected for the purpose of this study. The study applied systematic sampling method to select stories from The Standard and simple random sampling to select the stories from Daily Nation. A sample of 35 news articles (an average of 5 every day) for each of the newspapers and a maximum of 10 for each of the other categories were selected from 294 and 180 articles from The Standard and Daily Nation respectively. Details of each story were recorded in the coding sheet. This information was afterwards transferred to SPSS, a statistical data analysis programme. The study employs 11 of Johan Galtung’s 13 indicators of war/peace journalism to analyse the framing of the conflict. Galtung has proposed a new approach to reporting war and conflict that he terms 'peace journalism'. The two newspapers had an equal number of war journalism-framed stories (6 or 2%). Peace journalism framing was dominant in both newspapers. The findings contrast Galtung’s argument that in reporting war and conflict the media always give emphasis to war journalism frames.

Background: Cancer pain affects coping strategies in patients. Besides, social protection is a tool that helps to alter the patient’s encounter with cancer. This study aimed to investigate the relationship between social support, coping, and disease strategies. Methods: This was an analytical cross-sectional study with a quantitative approach, and conducted using a self-made social support questionnaire and the Billings and Mouse coping strategies questionnaire. The study population consisted of all the cancer patients in Kerman City, from September 2016 to March 2017; it was estimated to include 1400 people. Based on the Cochran formula, the study sample size was calculated as 300 cancer patients, which were collected using a systematic sampling method. Also, data analysis was carried out using the Pearson tests and regression in SPSS V. 21. Results: The results showed a statistically significant association of social support and coping with the disease strategies (P<0.01). Moreover, problem-focused coping has the most positive and direct relationship with social support. Regression analysis also showed that emotional aspects (kindness and shared positive actions), service-practical support, and financial support can predict the coping strategies with disease. Conclusion: According to the results, it is recommended to formulate a comprehensive care program and increase social support to enhance the problem-focused coping strategies among cancer patients.
