Background Although the incidence of diarrhea in Indonesia has declined in the last five years, the mortality rate in children under five years old is still high. Therefore, appropriate and comprehensive management of diarrhea is essential. There have been many studies on the role of zinc therapy and probiotic therapy in reducing the severity of acute diarrhea, but not many studies have compared the use of a combination of the two therapies tozinc therapy alone.Objective To compare the efficacy of zinc-probiotic combination therapy to zinc alone in reducing the severity of acute diarrhea.Methods We conducted a randomized, open-label, controlled trial from July 2009 to January 2010 in Adam Malik Hospital and Pirngadi Hospital, Medan. Children aged between 1 month and 5 years who met the criteria were divided into two groups. Group I received zinc sulphate (aged <6 months: 10 mg/day; aged 2:6 months: 20 mg/day) combined with heat-killed Lactobacillus acidophilus (3x101O CFU/day) for 10 days. Group II received only zinc sulphate at the same dosage as group I. Measurement of disease severity was based on the frequency of diarrhea (times/day) and the duration of diarrhea (hours) after initial drug consumption.Results Eighty subjects were enrolled, randomised, and divided equally into two groups. 40 children received zinc-probiotic in combination (group I) and the remainder (group II) received zinc alone. We observed significant differences in frequency of diarrhea (2.1 vs 3.1 times/day, P=0.001, 95%CI -1.62 to -0.49), and duration of diarrhea (52.1 vs. 72.6 hours, P=0.00l, 95%CI -30.91 to -10.18) in the two groups.Conclusion Combination of zinc-probiotic therapy was more effective in reducing the severity of acute diarrhea than zinc therapy alone in children under five years of age.

This paper introduces various smart ventilation methods for energy conservation in buildings, with a focus on occupant-based demand-controlled ventilation. An occupancy estimation algorithm is developed using a Bayesian Markov chain Monte Carlo algorithm based on indoor carbon dioxide concentrations. Experiments are conducted to control the outdoor airflow rate in real time according to the estimated number of occupants. Six different ventilation schemes are tested and compared with the ventilation standard of the American Society of Heating, Refrigerating, and AirConditioning Engineers. Our results show that occupant-based demand-controlled ventilation is more effective compared to other control schemes in terms the total ventilation air volume needed. The real-time ventilation control algorithm is applied successfully without any recursive problems. The occupancy estimation algorithm needs to be developed further to improve the estimation accuracy and reduce time delays.

Penelitian ini bertujuan untuk mengetahui pengaruh ketinggian air yang berbeda terhadap pertumbuhan dan kelangsungan hidup larva ikan botia (Chromobotia macracanthus, Bleeker). Hasil penelitian menunjukkan bahwa sintasan atau kelangsungan hidup tertinggi terdapat pada perlakuan B dengan ketinggian air 10 cm yaitu sebesar 98.88%, sedangkan kelangsungan hidup terendah terdapat pada perlakuan A dengan ketinggian air 5 cm yaitu sebesar 97.99%. Pertambahan bobot nilai tertinggi terjadi pada perlakuan A dengan ketinggian air 5 cm dengan nilai bobot rata–rata 0.02252 gr dan pertambahan bobot rata–rata terendah terjadi pada perlakuan C dengan ketinggian air 15 cm yaitu sebesar 0.01132 gr. Pertambahan panjang rata–rata tertinggi terjadi pada perlakuan A yaitu sebesar 0.42 cm dan yang terendah terjadi pada perlakuan B yaitu sebesar 0.29 cm. Parameter kualitas air selama penelitian masih dalam kisaran optimal dimana suhu 24,3–28,9oC, pH 6,5–7,0, DO 6,84–7,69 ppm, NH3 0,00–0,03 ppm, NO2 0,00–0,07 ppm. Analisis statistik dengan uji F diperoleh bahwa ketinggian air yang berbeda dalam pemeliharaan larva ikan botia (C. macracanthus, Bleeker) berbeda sangat nyata (P>0.01) terhadap pertambahan bobot dengan nilai Fhitung (21.00) > Ftabel (10.92), dan berbeda sangat nyata terhadap pertambahan panjang dengan nilai Fhitung (23.56) > Ftabel (10.92), sedangkan untuk sintasan atau kelangsungan hidup tidak berbeda nyata antar perlakuan. Hasil uji BNT menunjukkan, setiap perlakuan memberikan pengaruh terhadap pertumbuhan dan tidak berpengaruh terhadap kelangsungan hidup.The study aims to determine the effect of different water levels on the growth and survival of fish larvae Botia (Chromobotia macracanthus, Bleeker). The results showed that the survival rate was highest in treatment B with the water level was 10 cm which was equal to 98.88 %, whereas the lowest survival rate was found in treatment A with the water level was 5 cm which was equal to 97.99 %. The highest value of weight gain occurred in treatment A with average value in weight was 0.02252 g and the average weight gain was lowest in the treatment of C that reached 0.01132 g. The highest growth of length was occured in treatment A that was equal to 0.42 cm and the lowest occurred in treatment B that was 0.29 cm. Water quality parameters during the study were in the tolerance range where the optimum temperature were 24,3-28,9 oC , pH 6.5 to 7.0, DO 6.84 to 7.69 ppm, NH3 0.00 to 0.03 ppm , NO2 0.00 to 0.07 ppm . Statistical analysis by F test showed that the different water levels in the larval rearing of fish Botia (C. macracanthus, Bleeker) was significantly different ( P > 0.01) in the weight gain with the value of Fcount ( 21.00 ) > Ftable ( 10.92 ), and it was significantly different against the length with the value of F count ( 23:56 ) > F table ( 10.92), while for the survival rate showed has not significantly different between treatments. The LSD test showed that all the treatment were effected the growth rate, but not for survival rate.

The purpose of the study was to investigate the best practices of promoting a positive school learning climate among principals of Cluster Secondary Schools Malaysia according to principals' and teachers' perceptions. The Principal Instructional Management Rating Scale (PIMRS) modified by Hallinger and Murphy (1987), Latip (2006), Hatta (2010), Surayya (2016) was used as the data collection instrument through survey questionnaire. There were 871 respondents of different genders, ethnics, type of schools, and, position of responsibilities at schools were participated. The result of the study shows that the highest score was on dimension 'Developing and Enforcing Academic Standards' with mean 4.290 and standard deviation 0.814. It was followed respectively by 'Providing Incentives for Learning' mean 4.060 and standard deviation 0.904; 'Protecting Instructional Time' mean 3.855 and standard deviation 0.963 and 'Providing Incentives for Teachers' mean 3.607 and standard deviation 1.095. Meanwhile, the two best statements practiced by the principals were 'Use assemblies to honor students for their academic work and/or behavior in classroom' mean 4.39 and 'Encourage teachers to start class on time and teach to the end of the period' mean 4.38. It is hoped that this study will provide useful findings which will effectively assist the process of promoting a positive school learning climate among principals and teachers of secondary schools. Consequently, facilitate and improve students' academic performance in achieving the first class human capital who compatibly excellent nationally and internationally as stipulated in the purpose of establishing the Cluster Secondary schools by the Ministry of Education towards realization of Vision 2020 and the Education Blueprint 2013-2025 Malaysia.

This study was to determine the prevalence and socio-demographic associated factors for serious injury among adolescents in Malaysia. The study used data from the Malaysian Global School-based Health Survey which was conducted in 2012. Logistic regression analysis was used to establish associations. Of the 25,507 respondents, 34.9% (42.1% males and 27.8% females) reported having been in a serious injury. Compared to participants who were not bullied, those who reported being bullied were more likely to have sustained serious injury (aOR = 2.2; 95% CI [1.95-2.48]). Adolescents who were involved in physical fighting were 57.5% (aOR = 2.75; 95% CI [2.53-2.99]) and more likely to have sustained serious injury compared to those who were not involved in the fighting. Meanwhile, adolescents who used substances were 52.3% (aOR = 1.68 [1.52-1.85]) and more likely to have sustained serious injury compared to those who did not use substances. Serious injury is frequent among adolescents in Malaysia. Based on studies by Harel, suggestion where reduction of substance use and bullying may be assessed if they have an impact in reducing serious injury among adolescents. Furthermore, educational programmes that focus on the underlying causes and determinants of injury provide an effective and efficient method of injury prevention.
