Authors: Rabotyagova Yu. S. , Klyaritskaya I. L.
Published: May 2018

To determine the factors that affect the effectiveness of gastroesophageal reflux disease therapy, a correlation analysis was performed that included the international GERD questionnaire, the hospital anxiety and depression score (HADS), and data on the polymorphism of cytochrome P450 2C19 in 136 patients with different variants gastroesophageal reflux disease (GERD): reflux esophagitis (RE), non-erosive reflux disease (NERD) and reflux hypersensitivity (RH). The presence of a strong negative relationship between the favorable outcome of PPI therapy and the GERD score was demonstrated after 4 weeks of therapy in the RE, NERD and RH groups (p < 0.001). When analyzing the relationship between the HADS scale and the effectiveness of therapy, a strong negative correlation was found only in the RE group (p < 0.001), the fact that the metabolic rate of the PPI moderately correlated with the favorable outcome of therapy in the RH and NERD groups (p < 0.05).

Published: May 2018

The article presents the analysis of renin–angiotensin system and content precursor of aldosterone and their metabolites, investigated by methods of high-performance liquid chromatography and gas chromatography – mass-spectrometry in 49 patients with pheochromocytoma (РНЕО) and 28 patients with non-active adenoma of the adrenal cortex and 26 healthy people. In the group of patients with PHEO the increased blood levels оf aldosterone and urine excretion of 18-hydroxycorticosterone, tetrahydrocorticosterone and it 5-α form were obtained. These patients had features of hyporeninemic and hyperreninemic hyperaldosteronism. Positive correlations of urinary excretion of free normetanephrine with blood aldosterone, renin, corticosterone and 18-hydroxycorticosterone suggest the relationship between adrenal cortex and medulla.
Analysis of the treatment and preventive care quality for adults with periodontal diseases under the compulsory health insurance program in Saint Petersburg
Authors: Silin A. V. , Filatov V. N. , Leonova E. V. , Rizahanova O. A.
Published: May 2018

The present article revealed the results on evaluation of medical care quality in 430 patients with parodontologic diseases provided in 14 municipal and city dental policlinics in 2014-2016 under the compulsory health insurance (CHI) in Saint Petersburg. The performed analysis allows to compare the possibilities of therapeutic and diagnostic assistance to treat periodontitis, provided under CHI and regulated by the clinical recommendations developed by Russia Dental Association. Due to the developed clinical recommendations the quality dental care under CHI could be provided only on the initial and supportive treatment stages and considered to be therapeutic, thus the surgical treatment could not be fully provided. The types of medical services provided under CHI restrict the use of clinical recommendation (Russia Dental Association) to treat patients with periodontal diseases in dental policlinics and do not ensure the provision of entirely quality dental care under CHI. Therefore, the development of new criteria to include the full range of treatment and diagnostic dental services into the basic CHI is of high importance.

Authors: Samusenko A. A. , Rayanov N. V.
Published: May 2018

Acute appendicitis in children — the most common acute surgical disease of the abdominal cavity is found at any age. For children of the first 3 years of life, acute appendicitis is considered a rare disease and, according to various authors, occurs in 0.5-2% of cases. It is in young children that the diagnosis of acute appendicitis is complex and difficult, especially at the prehospital stage and therefore diagnostic errors are allowed.

Purpose: Tumor and patient characteristics of neuroendocrine tumors (NET) significantly change between geographical locations that probably induced by environmental and genetic factors throughout the world. Therefore, reporting single center experience may help clarifying epidemiological view and improving decision-making process. Materials and Methods: We performed retrospective analysis of 115 patients of NETs those who followed by Baskent University, department of Medical Oncology and department of General Surgery to record patients and tumors characteristics, treatment modalities, survival rates, and prognostic factors.  Results: Median overall survival (OS) time for all group and localized NETs were 44 and 24 months, respectively. Most common primary site was found as gastrointestinal system and then pancreatic region. Curative surgical resection rate was 46% and 8.5% of patients presented with carcinoid syndrome. Liver metastasis was far the most common metastatic site compared to lung, bone, and lymph node metastasis. Over 70 percent of patients were treated with chemotherapy and somatostatin analogs. Conclusion: Patients with higher grade, male gender, and advanced age (>65 years old) had poor survival rate. However, relatively low number of patients and less usage of (<10%) of new treatment modalities created limitations for producing future directions from our study.

TEACHER ACTION RESEARCH: ITS DIFFICULTIES AND IMPLICATIONS
Authors: Aguilar-de Borja Joanna Marie
Published: May 2018

Purpose: This study generally aimed to (1) identify the most difficult part of the action research process as evaluated by the teachers; (2) find out implications of conducting action research in teaching-learning process; and (3) identify the impact on teachers’ current and future instructional practices in conducting action research.

Methodology: Mixed method design which involves quantitative and qualitative methods of researchwas used. High school teachers in Colegio de San Juan de Letran Calamba who conducted action researches from 2012 - 2015 were the respondents of the study. The total number of teachers involved in action research projects is 27 - 41% from the Mathematics-Science and Technology cluster, 37% out of 27 from Socio-Linguistic Cluster, and 22% come from the MAPEH-TLE Cluster. These teachers then answered the survey instrument adapted and modified from the study of O’Connor, Greene, and Anderson (2000).

Main Results: Based on the results, writing the Framework of the Study is the most difficult part. All teachers agreed that action research is valuable to the teaching-learning process for both teachers and students. On the other hand, almost all of the teachers said that action research project positively impacted both students’ learning and teaching. This proves that action research as viewed and assessed by teachers has a major role in improving the teaching-learning process. Likewise, teachers proved that involving oneself in action research leads to professional growth of their career through ranking and promotions. School setting and curriculum have been improved through the positive results gained in action researches. Knowledge of statistics or data analyses was one of the hindrances encountered by teachers in conducting action research. It appears that time spent in conducting action research is one big factor that makes this activity difficult for teachers.

Implications: Parts of action research, which were considered very difficult for teachers should be the focus of training and development for teachers. Likewise, the number of teaching load and teacher tasks require too much time that they cannot devote for research. Thus, In order for teachers to conduct researches, there should be lesser teaching load to provide extra time for institutional researches and support more teacher researchers.

Limitations: The results of the evaluation of the teachers to the questionnaire were the bases in drawing out conclusions. Moreover, the effect of conducting action research through experimentation was not included in the study.

Soil erosion is a very severe problem in the highlands of Ethiopia, especially in Northern and central highlands of Ethiopia. In the country, efforts to conserve soil resources and prevent degradation dated back to the mid-1970s and 80s. However, the efforts put towards the promotion of the technologies, so far seem to have had limited impact in increasing the sustained use of conservation measures in different parts of the country, including Sabiya  Sayna Kebele. The main purpose of this study was, therefore, to assess the sustainable use of physical conservation measures introduced through a major soil conservation.. Specifically, the study was conducted to assess farmers’ perception towards the major introduced conservation structures; identify factors determining the adoption of these structures; and assess existing constraints to and options for sustained use of conservation structures in the study area. The study selected purposively of two sub-Kebeles where the recent intervention has already been implemented, and a total of 130 households were randomly selected from the sub-watersheds using the proportions-to-size technique of sample allocation.  The study recommends that adequate consideration of the significant influential factors should be taken so as to better promote the sustainable use and widespread adoption of introduced conservation structures.

Dairy co-operatives can improve access to market information, reduce costs and price risks of marketing and can increase producers’ access to technology, extension and related services and enhance bargaining power of dairy producers. The overall objective of the society is to alleviate members’ milk marketing problem and increase their income generated from the milk and milk by products.. So, this paper will find out the solution for those problems. The major objective of this study is to identify factors affecting members Participation in primary cooperatives in north Gondar zone. North Gondar Administrative Zone and in the zone 8 districts and 11 primary dairy cooperatives were selected purposively and 114 sample respondents were selected by using simple random sampling methods. Both qualitative and quantitative data as well as primary and secondary data were used in the study.. The result of the study indicated that except access to transport, feed availability and proximity all discrete and continuous variables had a significant association with members’ participation of the dairy cooperatives. The binary logistic regression result of members’ participation also shows that from the hypothesized thirteen independent variables only six variables were found to be significantly influenced members’ participation of primary dairy cooperatives. As a recommendation, the concerned bodies, members and dairy cooperatives should give emphasis on factors like transport access, number of milking cows, price of raw milk, training access, patronage dividend and access of credit to increase members’ participation in GA meeting, decision making, election and economic activities of dairy cooperatives.

The study was conducted in North Gondar Zone, Amhara region Ethiopia, to explore the various indigenous knowledge systems practiced in livestock production by small holder farmers. Both qualitative and quantitative data were collected from primary and secondary data sources. Qualitative data that helped to assess indigenous knowledge practices in the study area were collected through personal observation, and focus group discussions. In addition to this semi-structured questionnaires were distributed to 120 Households spread across the three districts of different PA administrative to collect relevant data. The data collected through questioner was organized and analyzed by using SPSS (version 20). The study revealed that a combination of crop residue and natural pasture is common sources of feed for most (45.8 %) of respondents. The indigenous knowledge regarding livestock production is considered as old as domestication of various livestock species. With regard to feed treatment practices, most (51.7%) of the farmers in the area treat the animal feed by using common salt in order to increase food palatability by the animals. Ethno-veterinary medicines is one of the common practice by households in North Gondar Zone. Even though most (65%) of households prefer modern disease treatment, about 78.3 % of farmers are using cultural medicine for treating different livestock diseases The main reason for using cultural medicine by farmers in the area is it’s easily availability, cheapest cost and its practical applicability. The major constraint of indigenous knowledge utilization in north Gondar zone is the resistance Development agents (28.3%) followed by other administrative bodies (22.5%) in the region. There is a high risk of extinction of indigenous knowledge if it is not documented. To avoid this loss, emphasis should be given on developing indigenous knowledge systems and documenting this unique knowledge into the mainstream knowledge. In addition to this, research should be done on the various methods of ethno-veterinary medicine and document the effective ones for use by the future generations. Moreover, research from a gender perspective is needed to document specialized ethno-veterinary knowledge not only of cattle but also of small stock such as sheep and chickens. It is important that livestock farmers share ideas on traditional knowledge with modern veterinarians in order to optimize productive capacity of herds and enhance sustainable rural livelihoods.

Though Rwanda is among the highest common bean producers and consumers, this crop is still challenged by different factors including root rot diseases resulting in low yield potential. Root rot diseases can cause up to 100% of yield loss. Despite different soil borne pathogens causing bean root rot diseases; there is no recent literature that clearly documents the most aggressive ones affecting common beans in Rwanda. This study aimed at identifying the root rot pathogens affecting bean crop in Rwanda. A survey was conducted to collect bean samples showing root rot symptoms in 12 agro -ecological zones where bean crop is mostly grown. The selection of samples was based on the level of contamination and the purity of cultures. A total number of 132 samples were therefore selected and considered for further analysis. The pathogen isolation was done in Rubona at Rwanda Agriculture and Animal Resources Development Board (RAB) Biotechnology and Pathology laboratory. Structural characterization of soil borne pathogens was also carried out along with pathogenicity evaluation. The growth rate of identified pathogens were significantly different (P<0.001). Significant differences were observed among isolates inoculated on both plantlets and seeds (P<001). Four root rot diseases were identified and characterized including Rhizoctonia spp, Fusarium spp,Sclerotium spp and several Pythium spp. The four pathogens were mostly observed in Northern and Southern parts of Rwanda than East and Western parts of Rwanda. Morphological characterization showed that Fusarium spp, Rhizoctonia spp and Sclerotium spp were predominant than Pythium species. Fusarium spp was identified as the most predominant fungal pathogen while Sclerotium spp was the most virulent pathogen. The present study suggests bean root rot disease control program to reduce losses associated with these diseases especially the use of resistant varieties since the fungi are widespread and survive in soils for a long period of time.

Published: May 2018

Two field experiments were carried out during the cropping seasons of 2016 and 2017 at the Teaching and Research Farm of the University of Agriculture, Makurdi, Benue State, Nigeria. The experiments sought to determine the effect of sweet potato vine orientation on growth and yield of sweet potato/maize intercropping system with a view to improve the productivity of maize/sweet potato intercropping in Makurdi. The experiment was a 2 x 2 x 3 split-split plot laid out in randomized complete block design with three replications. The main plot treatments were two cropping systems [sole cropping (sweet potato, maize), intercropping (sweet potato + maize)].The sub plot treatments were made up of two maize varieties (pop.66SR/ACR.91 SUWAH 1-SR and M2: pool18R/AK94DMRESR-Y). The sub-sub plot treatments comprised of three (3) sweet potato vine orientations (incline, loop and horizontal). The result obtained from the experiment showed sole cropping gave higher cob length, number of seeds per cob, cob weight, grain yield and 100-seed weight of maize than intercropping in both years. In all years, pool18R/AK94DMRESR-Y produced higher yield and yield parameters of maize than pop.66SR/ACR.91 SUWAH 1-SR irrespective of the cropping system. In 2016 and 2017, horizontal vine orientation gave higher vine length, root diameter, root length, number of saleable roots per hectare and weight of saleable roots than all the other vine orientations. Intercropping with pop.66SR/ACR.91 SUWAH 1-SR gave higher growth and yield parameters than intercropping with pool18R/AK94DMRESR-Y. All intercrop combinations had LER figures above 1.0 and LEC values above 0.25 in both years. CR values of sweet potato were consistently higher than those of maize in all intercrop combinations in 2016 and 2017

Rural tourism is considered as one of the essential elements making significant contributions to rural development in many developing countries. A well planned and adequately operated rural tourism sector provides job opportunities for local people, increases living standards, alleviates poverty, prevents migration, and ultimately makes it possible for rural people to enjoy living at their original places of residencies. All of these benefits encourage governments and all other relevant stakeholders to put more emphasis on rural tourism activities when planning and to implement rural development programs. The primary aim of this study was to examine the opportunities of sustainable rural tourism in the Eastern Black Sea Region of Turkey. It based on an extensive review of related literature, governmental reports, and experiences and observations of the researchers in the region. The study revealed that the Eastern Black Sea region has a remarkable rural tourism potential and it will make significant contributions to rural development in Turkey. Particularly highlands, thermal hotels, rural activities, farms, and agribusiness are increasingly attracting many domestic and international tourists in every passing year. However, environmental dimension of rural tourism is under risk because of unplanned housing and road constructions which put more pressure on agricultural lands and rural landscape. For this reason, it is important to consider economic, social, and environmental dimensions of sustainability when preparing and implementing rural tourism programs for the region.

The purpose of this study was to assess the relationship between teacher commitment to students learning needs and level of students’ discipline in public secondary schools in Naivasha sub-county, Kenya. The study targeted a total of 197 respondents (constituting 28 head teachers and 169 teachers). A total of 195 respondents participated in the study (169 teachers and 26 principals) participated giving a response rate of 99%. Purposive sampling technique was used to sample head teachers while Krejcie and Morgan’s (1970) table for determining sample size for teachers. Questionnaires were used as instrument for data collection. SPSS was used to analyze the data where both descriptive and inferential statistics were used. The analyzed data were presented in terms of graphs and tables. The results showed that there was a significant positive relationship between teacher commitment to students learning needs and level of students’ discipline (r = .271, p = .000). Therefore, the null hypothesis that there was no significant relationship between teacher commitment to students learning needs and level of students’ discipline was rejected at .05 level of confidence. The study therefore concluded that teacher commitment to students learning needs influences students’ discipline in secondary schools in Naivasha sub-county. It was recommended that teachers should be more committed to meeting the students’ learning needs. This can be achieved through holding discussions with parents on their children’s academic performance and character development.
