Pengetahuan, Tindakan dan Persepsi Masyarakat Tentang Kejadian Malaria dalam Kaitannya dengan Kondisi Lingkungan
The aim of this study was learning about society knowledge, attitude, and perception about malaria according to environmental conditions. This study was an analytic observational study with cross-sectional design. Samples were 20 years old visiting Puu Weri health center. Statistic test used is chi-square test. The results showed that there were no significant correlation between the occurrence of malaria and age, level of education, whereas there were correlation between the occurrence of malaria with social and cultural environment knowledge (p=0,020, OR=4,343), biological environment knowledge (p=0,024, OR=4,000), physical environment knowledge (p=0,043, OR=3,625), social and cultural environment practice (p=0,004, OR=5,700), biological environment (p=0,003, OR=6,338), physical environment (p=0,018, OR=4,735), cultural and social environment perception (p=0,017, OR=4,375), biological environment perception (p=0,020, OR=4,667), and physical environment perception (p=0,024, OR=5,185). It is concluded that there are correlations among society knowledge, practice, perception, and the occurrence of malaria accor-ding to environmental condition. It is suggested that the mass counseling of malaria prevention and eradication related with the environment condition must be improved by primary health center and health service of West Sumba rgency support.

TRISODIUM CITRATE USE IN DAIRY COWS AND EFFECTS ON DAILY MILK YIELD AND QUALITY
The aim of this study was to determine whether the use of trisodium citrate can reduce milk somatic cell counts and consequently increase the milk yield and quality in dairy cows on third and fourth lactation. Twelve holstein cows were divided into 2 groups, 5 of them were chosen as trial which have received orally 30 mg trisodium citrate per kg of body weight in diluted form daily during 7 days. Apart from daily milk yield , milk sampling was performed before, after and during trisodium citrate treatment in both trial and control groups. Individual milk protein, fat, total dry matter, milk pH, somatic cell counts and oxidation reduction potential (ORP) were measured in each of milk samples. There was no significant difference regarding daily milk yield, fat, protein, dry matter of milk and milk ORP values between 2 groups. But somatic cell counts were significantly lower in trisodium citrate-given group during experimental period. In conclusion, trisodium citrate may be useful for improving milk quality regarding somatic cell counts
Optimisation of stabiliser usage conditions in oat milk production using response surface methodology
Present study aimed to optimise stabiliser concentration and swelling time of oat in the production of oat milk using response surface methodology. The effects of independent variables (stabiliser concentration, swelling time) on dependent variables (rheological and sensory properties) were studied using a central composite rotatable design of experiments. Physico-chemical properties and colour values of samples were not significantly ( P > 0.05) correlated to stabiliser concentration and swelling time. While stabiliser concentration affected the consistency index ( P < 0.05), swelling time had no effect on the rheological properties. The stabiliser ratio affected the sensory texture of samples ( P < 0.05). The sensory scores did not increase with increasing K value, on the contrary, the samples with the highest K value had lower sensory scores ( P < 0.05). Considering the K value and sensory scores, the optimum stabiliser concentration and swelling time were determined as 0.102%, and 51.2 min, respectively
High-K volcanism in the Afyon region, western Turkey: from Si-oversaturated to Si-undersaturated volcanism
Volcanic rocks of the Afyon province (eastern
part of western Anatolia) make up a multistage potassic and ultrapotassic alkaline series dated from 14 to 12 Ma. The early-stage Si-oversaturated volcanic rocks around the Afyon city and further southward are trachyandesitic volcanic activity (14.23 ± 0.09 Ma). Late-stage Si-undersaturated volcanism in the southernmost part of the Afyon volcanic province took place in three episodes inferred from their stratigraphic relationships and ages. Melilite–
leucitites (11.50 ± 0.03 Ma), spotted rachyandesites, tephryphonolites and lamproites (11.91 ± 0.13 Ma) formed in the first episode; trachyandesites in the second episode and finally phonotephrites, phonolite, basaltic trachyandesites and nosean-bearing trachyandesites during the last episode.
The parameter Q [normative q-(ne + lc + kls + ol)] of western Anatolia volcanism clearly decreased southward with time becoming zero in the time interval 10–15 Ma.
The magmatism experienced a sudden change in the extent of Si saturation after 14 Ma, during late-stage volcanic activity of Afyon volcanic province at around 12 Ma, though there was some coexistence of Si-oversaturated and Si-undersaturated magmas during the whole life of Afyon volcanic province
Impact of Surgical Timing on Neurological Outcomes for Spinal Arachnoid Cyst: A Single Institution Series
Objective Spinal arachnoid cysts (SACs) are rare lesions that often present with back pain and myelopathy. There is a paucity of literature evaluating the impact of surgical timing on neurological outcomes for primary SAC management. To compare long-term neurological outcomes in patients who were managed differently and to understand natural progression of SAC. Methods We conducted a retrospective analysis of adult patients treated for SAC at our institution from 2010 to 2021, stratified into 3 groups (conservative management only, surgical management, or conservative followed by surgical management). Study outcome measures were neurological outcomes as measured by modified McCormick Neurologic Scale (MNS), postoperative complications, and cyst recurrence. Nonparametric analysis was performed to evaluate differences between groups for selected endpoints. Results Thirty-six patients with SAC were identified. Eighteen patients were managed surgically. The remaining 18 patients were managed conservatively with outpatient serial imaging, 7 of whom (38.9%) ultimately underwent surgical treatment due to neurological decline. Most common presenting symptoms included back pain (50.0%), extremity weakness (36.1%), and numbness/paresthesia (36.1%). Initial/preoperative (p = 0.017) and 1-year postoperative (p = 0.006) MNS were significantly different between the 3 groups, but not at 6 weeks or 6 months postoperatively (p > 0.05). Additionally, at 1 year, there was no difference in MNS between patients managed surgically and those managed conservatively but ultimately underwent surgery (p > 0.99). Conclusion Delayed surgical intervention in minimally symptomatic patients does not seem to result in worse long-term neurofunctional outcomes. At 1 year, postoperative MNS were significantly higher in both surgical groups, when compared to the conservative group highlighting worsening clinical picture regardless of preoperative observational status
Spatial diversity in passive time reversal communications
A time reversal mirror exploits spatial diversity to achieve spatial and temporal focusing, a useful property for communications in an environment with significant multipath. Taking advantage of spatial diversity involves using a number of receivers distributed in space. This paper presents the impact of spatial diversity in passive time reversal communications between a probe source (PS) and a vertical receive array using at-sea experimental data, while the PS is either fixed or moving at about 4 knots. The performance of two different approaches is compared in terms of output signal-to-noise ratio versus the number of receiver elements: (1) time reversal alone and (2) time reversal combined with adaptive channel equalization. The time-varying channel response due to source motion requires an adaptive channel equalizer such that approach (2) outperforms approach (1) by up to 13 dB as compared to 5 dB for a fixed source case. Experimental results around 3 kHz with a 1 kHz bandwidth illustrate that as few as two or three receivers (i.e., 2 or 4 in array aperture) can provide reasonable performance at ranges of 4.2 and 10 km in 118 in deep water.

Quantifying risks and interventions that have affected the burden of diarrhoea among children younger than 5 years: an analysis of the Global Burden of Disease Study 2017
Background Many countries have shown marked declines in diarrhoeal disease mortality among children younger
than 5 years. With this analysis, we provide updated results on diarrhoeal disease mortality among children younger
than 5 years from the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017) and use the
study’s comparative risk assessment to quantify trends and effects of risk factors, interventions, and broader
sociodemographic development on mortality changes in 195 countries and territories from 1990 to 2017.
Methods This analysis for GBD 2017 had three main components. Diarrhoea mortality was modelled using vital
registration data, demographic surveillance data, and verbal autopsy data in a predictive, Bayesian, ensemble
modelling tool; and the attribution of risk factors and interventions for diarrhoea were modelled in a counterfactual
framework that combines modelled population-level prevalence of the exposure to each risk or intervention with the
relative risk of diarrhoea given exposure to that factor. We assessed the relative and absolute change in diarrhoea
mortality rate between 1990 and 2017, and used the change in risk factor exposure and sociodemographic status to
explain differences in the trends of diarrhoea mortality among children younger than 5 years.
Findings Diarrhoea was responsible for an estimated 533 768 deaths (95% uncertainty interval 477 162–593145)
among children younger than 5 years globally in 2017, a rate of 78·4 deaths (70·1–87·1) per 100000 children.
The diarrhoea mortality rate ranged between countries by over 685 deaths per 100000 children. Diarrhoea mortality
per 100000 globally decreased by 69·6% (63·1–74·6) between 1990 and 2017. Among the risk factors considered in
this study, those responsible for the largest declines in the diarrhoea mortality rate were reduction in exposure to
unsafe sanitation (13·3% decrease, 11·2–15·5), childhood wasting (9·9% decrease, 9·6–10·2), and low use of oral
rehydration solution (6·9% decrease, 4·8–8·4).
Interpretation Diarrhoea mortality has declined substantially since 1990, although there are variations by country.
Improvements in sociodemographic indicators might explain some of these trends, but changes in exposure to risk
factors—particularly unsafe sanitation, childhood growth failure, and low use of oral rehydration solution—appear to
be related to the relative and absolute rates of decline in diarrhoea mortality. Although the most effective interventions
might vary by country or region, identifying and scaling up the interventions aimed at preventing and protecting
against diarrhoea that have already reduced diarrhoea mortality could further avert many thousands of deaths due to
this illness.SMA acknowledges the International Centre for Casemix and Clinical

Electric field processing: novel perspectives on allergenicity of milk proteins
Milk proteins are being widely used in formulated foods due to their excellent technological, functional and biological properties. However, the most representative proteins from casein and whey fractions are also recognized as major allergens and responsible for the prevalence of cows milk protein allergy (CMPA) in childhood. Electroheating technologies based on thermal processing of food due to application of moderate electric fields, also known by Ohmic Heating or Joule effect, are establishing a solid foothold in food industry. Currently, the influence of OH on allergenic aspects of milk proteins is under debate but still undisclosed. The occurrence of electrical effects in protein structure and its function has already been reported, thus the impact of OH over allergenicity should not be overlooked. Based on these recent findings it is then relevant to speculate about the impact of this emergent technology on the potential allergenicity of milk proteins.This study was supported by the Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UID/BIO/04469/2013 unit and COMPETE 2020 (POCI-01-0145-FEDER-006684) and BioTecNorte operation (NORTE-01-0145-FEDER-000004) funded by European Regional Development Fund under the scope of Norte2020, Programa Operacional Regional do Norte.
