It can be concluded that the module developed feasible used as teaching materials and has a high readability based on the responses of teachers and students

Pengembangan Teknologi Pembuatan Biopolimer Bernilai Ekonomi Tinggi Dari Limbah Tanaman Jagung (Zea Mays) Untuk Industri Makanan: Cmc (Carboxymethylcellulose)

Corncobs is agricultural waste that have ascent amounts every years. The purposes of this research were to obtain information cellulose alternative source from corncobs for material of CMC; get optimum condition of synthesis CMC with food grade of DS and the characteristic of pH, viscosity, purity CMC. Synthesis CMC through alkalization and carboxymethylation process. The variation of NaOH concentration are 7,93; 10,00; 15,00; 20,00; 22,07% in alkalization and variations amount of NaMCA are 4,5858; 5,0000; 6,0000; 7,0000; 7,4142 gram in carboxymethylation. The result was cellulose content in corncobs is 62,80 %. The optimum condition which obtained from 15% NaOH and 5,04 g NaMCA gave CMC with DS 0, 82 ; pH 7,64 ; purity 99,52 % ; and viscosity 25,40 cps

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Query Optimization in MySQL Database Using Index

The quality of a database design has a significant impact on the quality of an information system. Even if a system has been running for a long time, a programmer may forget to optimize a query in MySQL, even though optimization is critical as the amount of data is enormous. MySQL has an index function for tables that helps to speed up database searches. In essence, the index will be beneficial if utilized by the user's interests and wants; otherwise, the index, constructed randomly and in large quantities, would slow down database access. As a result, before constructing a database index, it is necessary to reconsider the rules and conduct a thorough examination

Knowledge And Practices Of Midwives Regarding Zika Virus In Kendari, Southeast Sulawesi, Indonesia

Background: In 2016 Zika virus infection became an International public health emergency concern.Objective: This study aimed to evaluate the knowledge and practice of midwives regarding the Zika virus.Methods: This research was an analytic study with a cross-sectional approach. A total of samples was 191 selected using a proportional random sampling technique. WHO questionnaire was used to collect data on knowledge and practice related to the Zika virus and a set of explanatory variables.Results: The midwife's knowledge of the Zika virus revealed that only the workplace and sources of information were associated with knowledge of the Zika virus infection. Public health center had a greater chance of having good knowledge than hospitals with OR: 5.130 (CI: 2.591-10.157) and first knew Zika information more than one year ago had a greater chance of having good knowledge than the first midwife knew about Zika on the day the study was conducted with OR: 3.035 (CI: 1.485-6.203).Conclusion: Knowledge and practice regarding Zika virus infection among midwives in Kendari city Indonesia was relatively good. Furthermore, midwives who work in the public health center had a five times chance compared to midwives who work in hospitals to have better knowledge related to the Zika virus
