Ultrathin Monolithic Zirconia Veneers: Reality or Future? Report of a Clinical Case and One-year Follow-up
Authors: Souza R , Barbosa F , Araújo G , Miyashita E , Bottino MA , Melo R , Zhang Y 
Published: December 2017

SUMMARY
Yttria-stabilized polycrystalline zirconia ceramics have greatly advanced over the past few years. High-translucent zirconia is a newly introduced ceramic that affords high strength and esthetics and that has significantly increased the clinical indications of monolithic zirconia restorations. Thus, the purpose of this case report was to evaluate the performance of ultrathin monolithic zirconia veneers adhesively luted to enamel surfaces after minimally invasive preparations; in addition, we aimed at presenting a clinical protocol for zirconia surface treatment in order to promote bonding effectiveness to resin cement. This type of restoration presented very acceptable esthetic results and decreased the risk of fracturing the veneer during try-in and clinical use. The results were still satisfactory after one-year follow-up. However, randomized, prospective, controlled clinical trials are required to determine the long-term clinical durability of this treatment.

Published: December 2017

SUMMARY

Objectives:
To monitor the real-time changes in light transmittance during composite curing and to use transmittance data to determine the curing times required for a complete polymerization.

Methods:
Three conventional and three bulk fill composites were cured with two light-emitting diode curing units at layer thicknesses of 2 mm and 4 mm. The real-time light transmittance data were collected by a UV-Vis spectrometer in the wavelength range of 350-550 nm, plotted against time (t) and fitted to an exponential function f(t), whose first derivative ΔT(t) = df(t)/dt represented the rate of transmittance change. As the changing transmittance reflects structural changes that occur during polymerization, ΔT(t) &gt; 0 was considered to indicate an ongoing polymerization, whereas ΔT(t) values approaching zero suggested a complete polymerization. This principle was used to determine times required for a complete polymerization (tcomplete) for each material/thickness/curing unit combination.

Results:
Light transmittance was significantly influenced by the material type, sample thickness, and curing unit, amounting to 2.9%-27.0% for the bulk fill and 0.7%-16.7% for the conventional composites. The values of tcomplete amounted to 15.3-23.3 seconds for the bulk fill composites at 2 mm, 20.2-33.3 seconds for the conventional composites at 2 mm, 26.9-42.1 seconds for the bulk fill composites at 4 mm, and 40.1-59.8 seconds for the conventional composites at 4 mm. Additionally, an exponential relationship was discovered between the light transmittance and tcomplete.

Conclusions:
Some of the tcomplete values considerably exceeded the curing times recommended by the manufacturers.

Published: December 2017

Hati merupakan organ penting dalam tubuh manusia. Organ ini merupakan pusat metabolisme, salah satunya adalah metabolisme obat. Pengobatan konvensional yang menggunakan bahan kimia dapat menimbulkan perubahan pada fungsi hati. Sedangkan pada pengobatan tradisional, efek pengobatan pada fungsi hati masih jarang dipublikasikan. Salah satu penggunaan obat tradisional adalah jamu sebagai sedatif. Sebuah penelitian diadakan di Balai Besar Litbang Tanaman Obat dan Obat Tradisional (B2P2TOOT) tahun 2013 untuk mengetahui perubahan terhadap fungsi hati pasien-pasien yang mendapatkan terapi ramuan jamu insomnia. Penelitian berupa observasi terhadap 30 pasien insomnia yang datang dan berobat di Klinik Saintifikasi Jamu Hortus Medicus. Pasien insomnia yang mendapat terapi ramuan jamu selama 14 hari diobservasi fungsi hatinya. Evaluasi dilakukan pada nilai laboratoris yang merepresentasikan fungsi hati (SGOT dan SGPT) pada hari ke-0 dan hari ke-14. Perbandingan hasil pemeriksaan sebelum dan sesudah terapi menggambarkan perbedaan yang tidak bermakna kadar SGOT dan SGPT subjek penelitian(p>0,05). Semua subjek memiliki nilai SGOT dan SGPT yang normal secara klinis dan laboratoris. Pemberian ramuan jamu untuk insomnia tidak mengganggu fungsi hati.

ENGLISH LANGUAGE DIASPORA AND THE HIT-AND-MISS EXPERIMENTATION WITH ENGLISH CURRICULUM IN BANGLADESH
Authors: Haque Mr. Md. Azizul 
Published: December 2017

Despite the common diasporic origin English in Bangladesh is neither a native nor a second language, but a foreign language, in countries like India and Pakistan, English is used as the second language. The chronological history ofÂ English in Bangladesh has both political as well as social elements, which influence the learning of English at every level ofÂ education. In the mid-90s there was a growing demand from the educationists in the country to change the English curriculum as per â€˜needs analysisâ€™, and the curriculum is restructured aligning with the communication needs and the syllabus was largely transformed into a communicative one. Yet research explores that the needs are not served for the learners tend to by-pass the cognitive part of the language learningâ€”thus failing to communicate properly. Now, in the second decade of the new millennium English curriculum along with other subjects has been made â€˜creativeâ€™ at pre-tertiary level, but debates are still on to evaluate whether the system complies with the current practices prevailing within the institutional premises. The total picture thus presents a very confusing answer to the questions why all these efforts are being futile and why the English language teaching fails to touch the three main domains of learningâ€”the cognitive, the affective and the psychomotor. The current study wants to explore whether such experiments with the curriculum and the dilemma of receiving or rejecting the idea of acculturation with largely an anti-colonial mindset hinder the desired performance of the language.
Islamic Religious Learning In Providing Understanding Of Radical Hazards Based On Affection Approach (Study on Islamic religious Subjects at Junior High School)
Authors: Kusen Kusen 
Published: December 2017

The word Islam and radical, is a familiar word to hear, even in many of the recent events carried out by a group of people who in the name of Islam. Understanding the radical concept has penetrated into various elements, included in education. In responsing to this, the goverment have to take an action through reorganizing the existing materials in Islamic lesson which is taught in educational institutions.
Rearrangement of islamic lesson is important. Because the existing material had proved that its inadequate to bear students who are tolerant, moderate, and inclusive. The proof can be seen from the number of terrorist and Islamic radicalism which is involving educated young people, both students, college students, or college graduates. Moreover, lately, there has been a tendency of systematic efforts by certain denominations to teach extreme ideological loyalist of religious doctrine among learners.
This paper tries to provide an understanding which related to radical concepts on the explanation of Islamic lesson materials in junior high school. So that, learners can understand more about the concept of islam which is peaceful not violence. One of the strategy in providing a radical understanding among learners is to develop Islamic lesson materials through compassion-based learning.

Time Series Modeling on Monthly Data of Tourist Arrivals in Nepal: An Alternative Approach
Authors: Subedi Amrit 
Published: December 2017

Background: There are various approaches of modeling on time series data. Most of the studies conducted regarding time series data are based on annual trend whereas very few concerned with data having monthly fluctuation. The data of tourist arrivals is an example of time series data with monthly fluctuation which reveals that there is higher number of tourist arrivals in some months/seasons whereas others have less number. Starting from January, it makes a complete cycle in every 12 months with 3 bends indicating that it can be captured by biquadratic function.Objective: To provide an alternative approach of modeling i.e. combination of Autoregressive model with polynomial (biquadratic) function on time series data with monthly/seasonal fluctuation and compare its adequacy with widely used cyclic autoregressive model i.e. AR (12).Materials and Methods: This study is based on monthly data of tourist arrivals in Nepal. Firstly, usual time series model AR (12) has been adopted and an alternative approach of modeling has been attempted combining AR and biquadratic function. The first part of the model i.e. AR represents annual trend whereas biquadratic part does for monthly fluctuation.Results: The fitted cyclic autoregressive model on monthly data of tourist arrivals is Est. Ym = 3614.33 + 0.9509Ym-12, (R2=0.80); Est. Ym indicates predicted tourist arrivals for mth month and Ym-12 indicates observed tourist arrivals in (m-12)th month and the combined model of AR and biquadratic function is Est. Yt(m) = -46464.6 + 1.000Yt-1 + 52911.56m - 17177m2 + 2043.95m3 - 79.43m4, (R2=0.78); Est. Yt(m) indicates predicted tourist arrivals for mth month of tth year and Yt-1 indicates average tourist arrivals in (t-1)th year. The AR model combined with polynomial function reveals normal and homoscedastic residuals more accurately compared to first one.Conclusion: The use of polynomial function combined with autoregressive model can be useful for time series data having seasonal fluctuation. It can be an alternative approach for picking up a good model for such type of data. Nepalese Journal of Statistics, 2017, Vol. 1, 41-54

Background: Patients with dementia might have higher risk for hemorrhagic complications with anticoagulant therapy prescribed for atrial fibrillation (AF). Objective: This study assesses the risks and benefits of warfarin, antiplatelets, and no treatment in patients with dementia and AF. Methods: Of 49,792 patients registered in the Swedish Dementia Registry 2007–2014, 8,096 (16%) had a previous diagnosis of AF. Cox proportional hazards models were used to calculate the risk for ischemic stroke (IS), nontraumatic intracranial hemorrhage, any-cause hemorrhage, and death. Results: Out of the 8,096 dementia patients with AF, 2,143 (26%) received warfarin treatment, 2,975 (37%) antiplatelet treatment, and 2,978 (37%) had no antithrombotic treatment at the time of dementia diagnosis. Patients on warfarin had fewer IS than those without treatment (5.2% versus 8.7%; p < 0.001) with no differences compared to antiplatelets. In adjusted analyses, warfarin was associated with a lower risk for IS (HR 0.76, CI 0.59–0.98), while antiplatelets were associated with increased risk (HR 1.25, CI 1.01–1.54) compared to no treatment. For any-cause hemorrhage, there was a higher risk with warfarin (HR 1.28, CI 1.03–1.59) compared to antiplatelets. Warfarin and antiplatelets were associated with a lower risk for death compared to no treatment. Conclusions: Warfarin treatment in Swedish patients with dementia is associated with lower risk of IS and mortality, and a small increase in any-cause hemorrhage. This study supports the use of warfarin in appropriate cases in patients with dementia. The low percentage of patients on warfarin treatment indicates that further gains in stroke prevention are possible.

OBJECTIVE: Methylxanthines are the most commonly prescribed drug in neonatal setups. However, Clinicians show indecision in choosing the right agent for Apnea of Prematurity in most of the developing countries. Present study aimed to compare rate of mortality and survival with normal neurodevelopment outcome at 18 to 24 months of corrected age, between Caffeine- and Aminophylline-treated infants for apnea of prematurity. METHODS: 240 infants were randomly allocated to caffeine and aminophylline for apnea of prematurity during February 2012 to January 2015. Long-term neurodevelopmental assessment was done only from children who had attained corrected age of 18 to 24 months during April 2014 to February 2016. Cognitive, language and motor deficits were assessed by Bayley Scale of infant and toddler development (BSID – III). Postnatal characteristics such as hearing and visual impairments during NICU stay were noted and same were followed up. RESULTS: Infants allocated to caffeine group showed 83% less risk of getting cognitive impairment (RR 0.16; CI 95% range 0.02 to 1.36), 50% less risk of developing motor deficits (RR 0.50; CI 95% range 0.12 to 1.95) and 24% less risk of developing language problems (RR 0.76; CI 95% range 0.36 to 1.58). However in all the neurodevelopment domains the difference between groups was not statistically significant. Risk of mortality in caffeine group was 9% less over aminophylline group which was statistically non-significant (RR – 0.92; CI 95% range – 0.45 to 1.84; p = 0.81). Physical growth parameters were found to be similar in both the groups. Risk of developing visual abnormality and hearing impairments was also statistically non-significant between the groups. CONCLUSION: Caffeine and aminophylline showed similar effects in reducing the rate of mortality and improving the survival without neurodevelopment delays; though the clinical significance of caffeine over aminophylline cannot be undermined.

Published: December 2017

Intensification of agricultural land use coupled with cultivation of modern varieties has remarkably increased in Bangladesh. This in turn has resulted in deterioration of soil fertility, with emergence of macro- and micro-nutrient deficiency of crops. With this point in view, a study was undertaken to evaluate the effect of different micronutrients on crop yield, and to determine the requirement of selected micronutrients for crops and cropping patterns in the Tista Meander Floodplain (AEZ 3). Experiments were conducted at BINA substation and farmers’ fields of Rangpur district within AEZ 3. In experiment 1, the field trials were done with six micronutrients (B, Zn, Cu, Mn, Fe & Mo) designed in an additive manner. These elements were imposed to the first crop and their residual effects were monitored on the next two crops over the patterns: wheat-mungbean-T. aman. The rates of micronutrient application were 3 kg Zn, 2 kg B, 2 kg Cu, 3 kg Mn, 5 kg Fe and 1 kg Mo per hectare, added as fertilizers such as ZnSO4.7H2O, H3BO3, CuSO4.5H2O, MnCl2, FeSO4.7H2O and Na2MoO4, respectively. Other nutrients viz. N, P, K & S were applied at recommended rates to all plots; rationale was followed for the second and third crops. Intercultural operations were done whenever required. The results revealed that across the experimental sites, the crops were quite responsive to the added Zn and B. Positive effect of Cu was also noted in some cases. In the following year (expt. 2), two micronutrients, Zn and B were taken into the same cropping pattern and designed in a way to determine whether 1stcrop, 2ndcrop or 3rdcrop application is necessary to achieve satisfactory crop yield. The rates of Zn application were 0, 2, 4 & 6 kg ha–1, and the rates for B were 0, 1.5 and 3 kg ha–1. The results show that Zn application at 4 kg ha–1 coupled with B application at 1.5 kg ha–1 to the first crop can meet their requirement for the subsequent two crops in a pattern. The present study suggests that cropping pattern based field trials with Zn, B and Cu need to be done at farm level in the high cropping intensity areas of this country in order to determine micronutrient requirement of cropsJ.

Variability and traits association in maize (Zea mays L.) for yield and yield associated characters
Authors: Ferdoush A , Haque MA , Rashid MM , Bari MAA 
Published: December 2017

Maize (Zea mays L.) is world’s third most important cereal crop that has a remarkable productive potential in Bangladesh. In Bangladesh, maize is the second most important cereal crop in terms of production. The selection for high yield with desirable traits depends on the genetic variability in the existing germplasm. Successful breeding programs need adequate genetic variation for selection and improvement based on necessity. The research was conducted in the experimental farm of the Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh during November 2015 to April 2016. The aim of this study was to evaluate the performance of 20 maize genotypes based on their yield and yield contributing characters to determine existing genetic variability. The extrapolated ANOVA for different yield contributing parameters showed a high degree of variation among the genotypes used. Correlation co-efficient analysis revealed that yield plant−1 (g) had positive and significant association with ear girth (cm), 1000-kernel weight (g), yield plot−1 (g), grain yield (tha−1) with dry weight. The genotypes differed significantly for most of the phenotypic traits. The phenotypic co-efficient of variation (PCV) was higher than genotypic co-efficient of variation (GCV) in all traits studied indicating that those traits were interacted with the environment. The traits under study expressed wide heritability estimates (26.81% to 99.95%). Among the characters, highest heritability was recorded for 1000-kernel weight (g). High heritability along with high genetic advance was noticed for 1000-kernel weight (g), yield plot−1 (g)and grain yield (tha−1). Considering different desirable traits P-12, Popcorn, V90-1, 988 were observed as superior genotypes. The data would be useful for proper identification and selection of appropriate parents in breeding programs to develop new maize varieties.J. Bangladesh Agril. Univ. 15(2): 193-198, December 2017
