South Minahasa Regency is one of regencies in the province of North Sulawesi, which had agro-climatic conditions suitable for the growth of rice plants. To determine the growth and development of the rice crop in the South Minahasa District, with various agro-climatic conditions can be simulated models of rice plants. This study aims to determine the potential for rice production in South Minahasa Regency and mapping potential for rice production in South Minahasa Regency. This research was conducted through the collection of climate data (solar radiation, air temperature, air humidity, while irradiation and precipitation) and the data on latitude and longitude coordinates. Implementation using simulation models of rice plants Rice Shierary V.2.1 to determine the potential of rice production and rice production potential mapping in South Minahasa district to use Photo Satellite Imagery processed through ArcView 3.3 software. Research results show the potential of rice production is the village Popontolen 6.11 ton ha-1, village Pakuweru 5.73 ton ha-1, and the Village Karowa 9.00 ton ha-1, the highest production potential are among the sites that Karowa Village 9.00 ton ha-1 is due to have the most ideal temperature for growth and development of paddy rice at an average of 23.12 ° C, and the average rainfall is 293.50 mm and 103.42 mm evapotranspiration. Data from the study indicate the potential for a higher yield than the data Provitas paddy rice official South Minahasa District of 2010-2014. This shows that the achievement of rice production in the district south minahasa not optimal. Hopefully the results of this study be input for agencies involved in this case the Department of Agriculture and Livestock South Minahasa regency in optimizing rice production with activities touching the supporting factors of production such as the provision of improved seed, fertilizer use impartial, repair dams and irrigation networks as well as the use of tools and agricultural machinery so as to increase farmers\u27 income
Training simulated patients: evaluation of a training approach using self-assessment and peer/tutor feedback to improve performance
<p>Abstract</p> <p>Background</p> <p>Most medical schools use simulated patients (SPs) for teaching. In this context the authenticity of role play and quality of feedback provided by SPs is of paramount importance. The available literature on SP training mostly addresses instructor led training where the SPs are given direction on their roles. This study focuses on the use of peer and self evaluation as a tool to train SPs.</p> <p>Methods</p> <p>SPs at the medical school participated in a staff development and training programme which included a) self-assessment of their performance while observing video-tapes of their role play using a structured guide and b) peer group assessment of their performance under tutor guidance. The pre and post training performance in relation to authenticity of role play and quality of feedback was blindly assessed by students and tutors using a validated instrument and the scores were compared. A focus group discussion and a questionnaire assessed acceptability of the training programme by the SPs.</p> <p>Results</p> <p>The post-training performance assessment scores were significantly higher (p < 0.05) than the pre-training scores. The degree of improvement in the quality of feedback provided to students was more when compared to the improvement of role play. The acceptability of the training by the SPs was very satisfactory scoring an average of 7.6 out of 10. The majority of the SPs requested the new method of training to be included in their current training programme as a regular feature.</p> <p>Conclusion</p> <p>Use of structured self-reflective and peer-interactive, practice based methods of SP training is recommended to improve SP performance. More studies on these methods of training may further refine SP training and lead to improvement of SP performance which in turn may positively impact medical education.</p
Financial incentives for return of service in underserved areas: a systematic review
<p>Abstract</p> <p>Background</p> <p>In many geographic regions, both in developing and in developed countries, the number of health workers is insufficient to achieve population health goals. Financial incentives for return of service are intended to alleviate health worker shortages: A (future) health worker enters into a contract to work for a number of years in an underserved area in exchange for a financial pay-off.</p> <p>Methods</p> <p>We carried out systematic literature searches of PubMed, the Excerpta Medica database, the Cumulative Index to Nursing and Allied Health Literature, and the National Health Services Economic Evaluation Database for studies evaluating outcomes of financial-incentive programs published up to February 2009. To identify articles for review, we combined three search themes (health workers or students, underserved areas, and financial incentives). In the initial search, we identified 10,495 unique articles, 10,302 of which were excluded based on their titles or abstracts. We conducted full-text reviews of the remaining 193 articles and of 26 additional articles identified in reference lists or by colleagues. Forty-three articles were included in the final review. We extracted from these articles information on the financial-incentive programs (name, location, period of operation, objectives, target groups, definition of underserved area, financial incentives and obligation) and information on the individual studies (authors, publication dates, types of study outcomes, study design, sample criteria and sample size, data sources, outcome measures and study findings, conclusions, and methodological limitations). We reviewed program results (descriptions of recruitment, retention, and participant satisfaction), program effects (effectiveness in influencing health workers to provide care, to remain, and to be satisfied with work and personal life in underserved areas), and program impacts (effectiveness in influencing health systems and health outcomes).</p> <p>Results</p> <p>Of the 43 reviewed studies 34 investigated financial-incentive programs in the US. The remaining studies evaluated programs in Japan (five studies), Canada (two), New Zealand (one) and South Africa (one). The programs started between 1930 and 1998. We identified five different types of programs (service-requiring scholarships, educational loans with service requirements, service-option educational loans, loan repayment programs, and direct financial incentives). Financial incentives to serve for one year in an underserved area ranged from year-2000 United States dollars 1,358 to 28,470. All reviewed studies were observational. The random-effects estimate of the pooled proportion of all eligible program participants who had either fulfilled their obligation or were fulfilling it at the time of the study was 71% (95% confidence interval 60â80%). Seven studies compared retention in the <it>same </it>(underserved) area between program participants and non-participants. Six studies found that participants were less likely than non-participants to remain in the same area (five studies reported the difference to be statistically significant, while one study did not report a significance level); one study did not find a significant difference in retention in the same area. Thirteen studies compared provision of care or retention in <it>any </it>underserved area between participants and non-participants. Eleven studies found that participants were more likely to (continue to) practice in any underserved area (nine studies reported the difference to be statistically significant, while two studies did not provide the results of a significance test); two studies found that program participants were significantly less likely than non-participants to remain in any underserved area. Seven studies investigated the satisfaction of participants with their work and personal lives in underserved areas.</p> <p>Conclusion</p> <p>Financial-incentive programs for return of service are one of the few health policy interventions intended to improve the distribution of human resources for health on which substantial evidence exists. However, the majority of studies are from the US, and only one study reports findings from a developing country, limiting generalizability. The existing studies show that financial-incentive programs have placed substantial numbers of health workers in underserved areas and that program participants are more likely than non-participants to work in underserved areas in the long run, even though they are less likely to remain at the site of original placement. As none of the existing studies can fully rule out that the observed differences between participants and non-participants are due to selection effects, the evidence to date does not allow the inference that the programs have caused increases in the supply of health workers to underserved areas.</p
Assessing predictions on fitness effects of missense variants in calmodulin
This paper reports the evaluation of predictions for the \u201cCALM1\u201d challenge in the fifth round of the Critical Assessment of Genome Interpretation held in 2018. In the challenge, the participants were asked to predict effects on yeast growth caused by missense variants of human calmodulin, a highly conserved protein in eukaryotic cells sensing calcium concentration. The performance of predictors implementing different algorithms and methods is similar. Most predictors are able to identify the deleterious or tolerated variants with modest accuracy, with a baseline predictor based purely on sequence conservation slightly outperforming the submitted predictions. Nevertheless, we think that the accuracy of predictions remains far from satisfactory, and the field awaits substantial improvements. The most poorly predicted variants in this round surround functional CALM1 sites that bind calcium or peptide, which suggests that better incorporation of structural analysis may help improve predictions

Mapping DNA damageâdependent genetic interactions in yeast via party mating and barcode fusion genetics
Abstract Conditionâdependent genetic interactions can reveal functional relationships between genes that are not evident under standard culture conditions. Stateâofâtheâart yeast genetic interaction mapping, which relies on robotic manipulation of arrays of doubleâmutant strains, does not scale readily to multiâcondition studies. Here, we describe barcode fusion genetics to map genetic interactions (BFGâGI), by which doubleâmutant strains generated via en masse âpartyâ mating can also be monitored en masse for growth to detect genetic interactions. By using siteâspecific recombination to fuse two DNA barcodes, each representing a specific gene deletion, BFGâGI enables multiplexed quantitative tracking of double mutants via nextâgeneration sequencing. We applied BFGâGI to a matrix of DNA repair genes under nine different conditions, including methyl methanesulfonate (MMS), 4ânitroquinoline 1âoxide (4NQO), bleomycin, zeocin, and three other DNAâdamaging environments. BFGâGI recapitulated known genetic interactions and yielded new conditionâdependent genetic interactions. We validated and further explored a subnetwork of conditionâdependent genetic interactions involving MAG1,SLX4, and genes encoding the Shu complex, and inferred that loss of the Shu complex leads to an increase in the activation of the checkpoint protein kinase Rad53
