Published: January 2021

Odor pollution is an increasing problem in Vietnam as a tropical country during the urbanization and industrialization. The odor from sewage systems, farms of poultry, pig, and beef, food processing companies, composting factory, and landfills is a severe problem in many nearby residential areas. In this study, two lab-scale biofiltration systems where pristine local bio-media and cultured bio-media with specially formulated microorganisms were employed in biofilters and bio-trickling filter for controls of odor (i.e., hydrogen sulfide and ammonia) from composting process were fabricated and operated. The odorous gas flow was created by composting solid waste collected from an agricultural market (i.e., mainly vegetable), containing low concentrations of 1.32 ± 0.32 mgNH3 m-3 and 5.20 ± 0.28 mgH2S m-3 under stable condition. For the biofilter model, commercial compost and cow manure were used as substrates and packed into the models. For the bio-trickling filter model, K3 bio-media with biofilm developed by contacting activated sludge was used as packing material. The results showed that adding specially formulated microorganisms could reduce adaption time and lead to slightly better odor control performance. Among the substrates, cow manure provided the highest odorous gas removal efficiency of ≥ 90% during the stable phase with the elimination capacity of 0.0492 gNH3 m-3 h-1 and 0.225 gH2S m-3 h-1. The study results show a high potential of cow manure biofilter for control of H2S and NH3 gases in the practical application under Vietnam’s condition.

Published: January 2021

The utilization of hydroxyapatite as an adsorbent has been extensively tested to remove the dye and heavy metal. Yet the adsorbent loss to the environment may lead to secondary pollutant issues. Consequently, the hydroxyapatite was incorporated with Fe3O4 amount variation to solve the secondary pollutant problem by utilizing the magnetic properties of Fe3O4 to recollect the adsorbent. In this work, FESEM images showed a mixture of nano-sizes rods and spherical particles corresponded to the presence of hydroxyapatite and Fe3O4 as a composite. The study found that hydroxyapatite- Fe3O4 (100 wt %) could eliminate 12.434 mg methylene blue/g adsorbent after 4 hours. The hydroxyapatite also gained improvement in its surface area from 59.8m2/g to 75.2m2/g when Fe3O4 is added. In addition, the adsorption of methylene blue fits the Freundlich isotherms and pseudo-second-order kinetic model. Furthermore, the methylene blue removal using hydroxyapatite-Fe3O4 composite can be kept at 80% even after 4 times experiments, showing the recyclability of hydroxyapatite-Fe3O4.

Published: January 2021

Despite extensive research since the first report of medication-related osteonecrosis of the jaw (MRONJ) in 2003, the optimal treatment and preventive modalities for the condition are not clear. Therefore, its management has been a concern in dentistry, oral and maxillofacial surgery, as well as departments involved in the treatment of cancers and/or bone diseases worldwide. Several cases of MRONJ could not be cured by conventional treatment strategies, as per the recommendations in various position papers. Therefore, a number of studies, including randomized controlled trials, have been conducted to examine the efficacy of novel therapies. However, no definite treatment modality has been determined. Several types of cell therapies have been documented. 10 animal studies and 5 case reports have been documented, in which autologous transplantation of cells has been carried out in MRONJ patients. Although these reports showed the efficacy of cell therapy, they were not large-scale, statistically accurate clinical studies; hence, the efficacy of cell therapy for this condition is not certain. However, the efficacy of MRONJ treatment using mesenchymal stromal cell (MSC) sheets has been investigated since 2013. This has been confirmed through various experiments in which MSC sheets were transplanted into model rats and beagle dogs exhibiting MRONJ-like lesions. Based on these results, a clinical study of MRONJ treatment using periodontal ligament-derived MSC sheets is being currently planned.

The research objective to develop a model of ummah fund utilization in the form of Cheap Qurban Syariah Investment (CQSI) with the synergy between the purpose of worship and the value of social benefits for the ummah empowerment. The study method used in the model design analyzes the beef cattle market's behavior, and a cost-benefit analysis of sharia investment in the pattern of profit sharing, the added value of beef cattle fattening efforts. Using the cost-benefit analysis of the profit-sharing partnership scheme, it was found that investment in cheap Qurban programs reduced the cost of Qurban borne by participants by 19.79% without lowering the Share of income received by beef cattle breeder partners and management fees for managing institutions. The more extended flexibility of procurement of feeder cattle when the conditions of low market demand and the reduced pressure on demand for ready-to-cut cattle at the time of Qurban worship will indirectly reduce the excessive fluctuations in commodity market prices. Based on the model developed, it can be concluded that cheap Qurban programs can encourage the utilization of the potential of ummah funds for farmers' economic empowerment, business opportunities for entrepreneurs, and Islamic institutions and indirectly help stabilize commodity prices for beef cattle without reducing the actual value of worship.

Mathematics exists as rooted in human ideas, ways, and techniques to respond to their environments. Along with its development, mathematics has been taught through formal education or schooling in the flat- not flexible ways and far from students' social and cultural lives. Indonesia is rich with culture, including the Special Region of Yogyakarta (DIY). It is called a city of culture. Educators are not yet aware of this richness in the learning process to integrate it as the starting point. It is hard to find in mathematics textbooks in Indonesia, which put cultural context as starting points. Therefore, this study aims to explore Yogyakarta's culture in terms of contexts used in mathematics learning.  It is an ethnography study. Furthermore, the data was collected through literature artifacts, field observation, and interviews with resource persons who understand the seasons, system, and calculation of birth and death days. It is to clarify the researcher's understanding of the literature. This study showed that Yogyakarta's people use mathematical modeling to determine the seasons' system and funerary dates. These models have the potential to be used as a starting point in learning mathematics.

Leptospirosis is associated with occupations which exposed workers to contaminated environments. The risk of leptospirosis exposure in the market as a gathering place for many people needs to be assessed, to obtain the basis for decision making to anticipate leptospirosis transmission. This study aimed to determine the relationship between market environmental conditions including market sanitation conditions, the level of rat density and the presence of leptospira-positive rats  toward the history of leptospirosis exposure among market workers (traders and janitors). A cross sectional study conducted in 35 markets in Banjarnegara and 175 market workers randomly selected. Blood samples analysed using ELISA against 40 Kda pathogenic Leptospira protein. Rat trapping  conducted in each market for two days with 100 traps. The caught mice examined with Polymerase Chain Reaction (PCR) to detect the presence of Leptospira bacteria in their kidneys. Leptospirosis exposure was spread in 17 markets in Banjarnegara. The PCR examination showed that the pathogenic Leptospira infected rats were spread in four markets in Banjarnegara. Chi square test showed that the hygene condition in market area was significantly associated with the leptospirosis exposure. Markets workers (traders and janitors) were at risk for leptospirosis proved by high seroprevalence of leptospirosis in this study.

OBJECTIVE

Insulin resistance and obesity are independently associated with type 1 diabetes (T1D) and are known risk factors for cardiovascular and kidney diseases, the leading causes of death in T1D. We evaluated the effect of BMI on cardiovascular and kidney outcomes in youth with T1D versus control youth with normal weight or obesity and youth with type 2 diabetes (T2D).

RESEARCH DESIGN AND METHODS

Pubertal youth (n = 284) aged 12–21 years underwent assessments of resting heart rate (RHR), systolic blood pressure (SBP) and diastolic blood pressure (DBP), leptin, hs-CRP, adiponectin, ratio of urine albumin to creatinine, and estimated glomerular filtration rate. Participants with T1D underwent bicycle ergometry for VO2peak, monitoring for peripheral brachial artery distensibility (BAD), endothelial function testing for reactive hyperemic index, and aortic MRI for central arterial stiffness or shear.

RESULTS

In adolescents with T1D, RHR, SBP, DBP, mean arterial pressure, leptin, hs-CRP, and hypertension prevalence were significantly higher, and BAD, descending aorta pulse wave velocity, and VO2peak lower with an obese versus normal BMI. Although hypertension prevalence and RHR were highest in obese adolescents with T1D and adiponectin lowest in youth with T2D, other measures were similar between obese adolescents with T1D and those with T2D.

CONCLUSIONS

Obesity, now increasingly prevalent in people with T1D, correlates with a less favorable cardiovascular and kidney risk profile, nearly approximating the phenotype of youth with T2D. Focused lifestyle management in youth-onset T1D is critically needed to reduce cardiovascular risk.

Published: January 2021

Tässä artikkelissa analysoimme Tampereen yliopiston organisaatiouudistukseen ja erityisesti sen uuteen brändi- ja viestintästrategiaan kytkeytyviä legitimiteettikamppailuja hybridissä mediatilassa. Aineistona käytämme sekä journalistisesta mediasta (n=39) että sosiaalisesta mediasta (n=9 303) kerättyjä puheenvuoroja. Käsitteellistämme Tampereen yliopistouudistusta koskevat huolet uuden muotoisen yliopiston legitimiteettiä koskevina argumentteina ja keskusteluina. Niiden avulla tutkimme, millä tavoin uudistettua Tampereen yliopistoa pyrittiin legitimoimaan ja delegitimoimaan median ja sosiaalisen median julkisissa keskusteluissa keväällä 2020 ja millaista vuorovaikutusta hybridin mediatilan eri mediamuotojen välillä voidaan havaita. Analyysimme eri mediamuodoissa esiintyvistä legitimiteetin arvioista osoittaa, miten mediatilan monimuotoistuminen tuottaa ongelmia monikohteiselle sidosryhmäviestinnälle, jossa organisaation legitimiteettiä pyritään muutostilanteessa rakentamaan. Tuloksemme korostavat viestinnän ja viestintätyylien merkitystä legitimaatiossa: kamppailujen keskiössä on yliopiston uudenlainen, yritysmaailmasta ammentava viestintätyyli, jonka metaforat päätyvät verkkokeskusteluissa kritiikin työvälineiksi.

Teachers’ Perception toward the Policy of Eliminating National Exam
Authors: Aziz Abd , Rohman Khabibur
Published: January 2021

This study analyzed teachers' perceptions toward the national exam elimination policy, starting in 2020 at both the primary and secondary school levels. This research implemented an explorative qualitative approach to teachers' perceptions of eliminating the national exam issue. This research employed interviews with 21 purposively chosen informants who were teachers of primary and secondary schools. Accordingly, this research also employed a secondary data collection method in the form of an online survey of 190 formal education teachers. The result of the study showed that the teachers argued about the national exam in many aspects. The curriculum is considered too narrow, too much attention for cognitive aspect, and does not accommodate students’ potential diversity. The national exam is also defective on both juridical and theoretical. However, eliminating the national exam worried the teachers regarding the drop in students' learning motivation and the gap in schools’ education quality. Teachers need to know that national exams are not the only reason to make students study hard. Teachers should foster students' internal motivation by emphasizing that learning should not occur because of exams.

Published: January 2021

This research aimed to determine the effect of the Guided Discovery Blended Learning (GDBL) strategy on concept mastery of the human excretory system. The research method was quasi-experimental with a pretest-posttest control group design. The samples consisted of the eleventh-grade students of Senior High school Jakarta in 2019/2020. Class MIPA-2 was the control class taught using Guided Discovery, and class MIPA-4 were the experimental class taught using GDBL. The learning process had been carried out both online and in the classroom. Research data were collected by integrating essay tests, students' responses to learning strategies, and observation sheets of syntax implementation. The data were descriptively analyzed and tested using ANCOVA. The normality test was performed using the Kolmogorov-Smirnov formula, and the homogeneity test was performed using Levene's test. The statistical tests indicated that the data were normally distributed and homogeneous; thus, ANCOVA analysis using SPSS 24 was performed. The data analysis with the ANCOVA test at 0,05 significance level obtained p value = 0.000, which means that H0 was rejected. The research result implied that GDBL affected students' concept mastery of the human excretory system. It cultivated habits to independently rearrange the concept through teachers' guidance, both from sourcebooks and online media. GDBL can be used as an alternative for biology studies.

Poor mathematical communication skills and motivation are influenced by several factors, such as the use of learning models used by teachers in learning. The use of appropriate learning models can improve students’ mathematical communication skills and motivation. This study aimed to determine the effect of the discussion learning model using Google Classroom and Google Form on students' mathematical communication in terms of students’ learning motivation. This type of research is quasi-experimental. Data were analyzed using two-way analysis of variance with unequal cells. Based on the results, it can be concluded that the discussion learning model using Google Classroom provided better communication skills than the learning model using Google Form, (2) there was no difference in the effect of learning motivation on students' mathematical communication, and (3) there was no interaction between learning model and learning motivation towards students' mathematical communication skills. Further research is needed to develop learning models using Google Classroom and Google Form by taking into account the characteristics of other students that are adjusted to the school curriculum.

This study evaluates the performance of some evapotranspiration models at Ile – Ife (7o 33’ N, 4o 33’ E) Nigeria. This was to identify suitable evapotranspiration (ET) models at the study site and to provide useful information for standardizing evapotranspiration estimations at a tropical location. Meteorological parameters (wind speed, relative humidity, temperature, solar radiation, soil heat flux, and net radiation) were routinely measured at the Obafemi Awolowo University (OAU) Meteorological Station located within the Teaching and Research Farm of the campus for a period of a month (1st – 29th July 2014). Nine standardized models for the estimation of ET; Penman-Monteith (FAO-56 PM), Priestly-Taylor (PT), Makkink (MAKK), Jensen-Haise (JH), Hargreaves-Samani (HS), Ivanov (IVA), Modified Romanenko (MROM), FAO-24 Radiation (FAO-24 RAD) and Turc (TURC) models were employed. The ET values obtained from these models were then compared to the estimated values obtained from the FAO-56 PM equation recommended as the international standard method for determining reference ET. The estimation of the ET obtained from FAO – 56 PM model ranged between 0.426 – 2.239 mm/day, MAKK, JH, and HS gave estimation closest to this, ranging from 0.544 – 2.272 mm/day. The estimation of ET from other models revealed that PT has the highest value ranging between 1.323 – 6.936 mm/day, followed closely was FAO – 24 RAD with values ranging between 1.197 – 6.500 mm/day, values of IVA model ranged from 0.620 – 1.829 mm/day, MROM value ranged from 1.240 – 3.659 mm/day, TURC has the least value ranging from 0.190 – 0.584 mm/day. Using the result of the mean biased error and regression analysis, JH model compared best with the FAO – 56 PM with coefficient of determination (R2) = 0.927; slope (b) = 0.957; mean biased error (MBE) = 0.133, this was followed closely by HS with value R2 = 0.929; b = 1.199; MBE = - 0.075 and MAKK with the value R2 = 0.931; b = 1.198; MBE = - 0.052. However, the other models showed significant over or underestimation of the ET benchmark values. The performance of the other models showed no improvement after they were recalibrated by adjusting their original coefficients. Thus, six out of the ET models employed in this study [the Priestly-Taylor (PT), Makkink (MAKK), Jensen-Haise (JH), Hargreaves-Samani (HS), FAO-24 Radiation (FAO-24 RAD) and Turc (TURC)] were found suitable for the climatic region of Ile – Ife after the adjustment of their coefficients.
