PEMANFAATAN TAMAN BACAAN MASYARAKAT (TBM) DALAM MENINGKATKAN MINAT BACA REMAJA (Studi Kasus di TBM Gunung Ilmu)
Authors: Susanti Dini , Santi Santi 
Published: November 2019

Saat ini kurangnya kegemaran membaca di kalangan remaja terjadi karena remaja telah diberikan informasi secara instan yang biasa diperoleh dari siaran TV dan media elektronik lainnya. Di samping itu, para remaja saat ini menganggap membaca merupakan hal yang membosankan. Padahal dengan membaca kita bisa memperluas kemampuan pengetahuan kita, yang membuat kita untuk lebih tanggap terhadap lingkungan sekitar kita. Membaca menurut Hodgson dalam Tarigan (2015 : 7), adalah suatu proses yang dilakukan serta dipergunakan oleh pembaca untuk memperoleh pesan, yang hendak disampaikan oleh penulis melalui media kata-kata / bahasa tulis. Sedangkan dari segi linguistik, membaca adalah suatu proses penyandian kembali dan pembacaan sandi, berlainan dengan berbicara dan menulis yang justru melibatkan penyandian. Tujuan dari dilakukannya penelitian ini, yaitu : (1) Untuk mengetahui sampai mana pengetahuan remaja tentang keberadaan TBM. (2) Untuk mendeskripsikan minat dan pemanfaatan TBM oleh remaja sebagai pusat media pembelajaran. (3) Untuk mengetahui kendala-kendala yang dihadapi oleh para remaja hingga saat ini.Penelitian ini menggunakan pendekatan kualitatif dengan metode deskriptif, untuk instrumen yang digunakan yaitu observasi, wawancara, dan studi kepustakaan. Sasaran atau sumber data yang dipakai dalam penelitian ini adalah Pengelola berjumlah 1 orang, Pemilik TBM Gunung Ilmu berjumlah 1 orang, serta pengunjung remaja dari TBM Gunung Ilmu berjumlah 3 orang. Jadi, total nya 5 orang sampel yang dipakai dalam penelitian ini. Awal di didirikan, remaja masih belum ingin datang ke TBM. Namun, sekarang remaja yang datang sudah meningkat, karena pengelola mengadakan beberapa kegiatan selain melakukan kegiatan membaca dan sharing ilmu, seperti kegiatan penyuluhan , dan sebagainya. Masih kurangnya minat remaja untuk membaca buku, apalagi untuk datang ke perpustakaan atau TBM sekitar rumahnya, mereka lebih mementingkan bermain online games, sosmed di gadget mereka, nongkrong di kafe bersama teman sebaya yang tidak memiliki tujuan kegiatan yang jelas. Kendala yang sering dihadapi oleh remaja salah satunya yaitu masih optimal nya promosi yang dilakukan pengelola dalam mengajak mereka agar mau datang dan mengikuti kegiatan yang ada di TBM.

Online Worker Fraud and Evolving Threats to the Integrity of MTurk Data: A Discussion of Virtual Private Servers and the Limitations of IP-Based Screening Procedures
Authors: Dennis Sean A. , Goodson Brian M. , Pearson Christopher A. 
Published: November 2019

ABSTRACT
We identify a pervasive, yet previously undocumented threat to the reliability of MTurk data—and discuss how this issue is symptomatic of opportunities and incentives that facilitate fraudulent behavior within online recruitment platforms. In doing so, we explain how IP addresses were never intended to identify individuals and are likely insufficient to identify and mitigate emergent risks around data integrity. We discuss MTurk samples for two studies that include alarming proportions of participants who circumvent an entire set of conventional sample screening methods—and provide disturbingly low-quality responses. These “bad actors” exploited inherent limitations of IP screening procedures by using virtual private servers (VPS) that concealed the IP address of their local devices. While service providers now help target this abuse, the underlying limitations of IP screening procedures remain. Our findings emphasize the importance of continued diligence within the research community to identify and mitigate evolving threats to data integrity.

OBJECTIVE
Identifying maturity-onset diabetes of the young (MODY) in pediatric populations close to diabetes diagnosis is difficult. Misdiagnosis and unnecessary insulin treatment are common. We aimed to identify the discriminatory clinical features at diabetes diagnosis of patients with glucokinase (GCK), hepatocyte nuclear factor-1A (HNF1A), and HNF4A MODY in the pediatric population.

RESEARCH DESIGN AND METHODS
Swedish patients (n = 3,933) aged 1–18 years, diagnosed with diabetes May 2005 to December 2010, were recruited from the national consecutive prospective cohort Better Diabetes Diagnosis. Clinical data, islet autoantibodies (GAD insulinoma antigen-2, zinc transporter 8, and insulin autoantibodies), HLA type, and C-peptide were collected at diagnosis. MODY was identified by sequencing GCK, HNF1A, and HNF4A, through either routine clinical or research testing.

RESULTS
The minimal prevalence of MODY was 1.2%. Discriminatory factors for MODY at diagnosis included four islet autoantibody negativity (100% vs. 11% not-known MODY; P = 2 × 10−44), HbA1c (7.0% vs. 10.7% [53 vs. 93 mmol/mol]; P = 1 × 10−20), plasma glucose (11.7 vs. 26.7 mmol/L; P = 3 × 10−19), parental diabetes (63% vs. 12%; P = 1 × 10−15), and diabetic ketoacidosis (0% vs. 15%; P = 0.001). Testing 303 autoantibody-negative patients identified 46 patients with MODY (detection rate 15%). Limiting testing to the 73 islet autoantibody-negative patients with HbA1c &lt;7.5% (58 mmol/mol) at diagnosis identified 36 out of 46 (78%) patients with MODY (detection rate 49%). On follow-up, the 46 patients with MODY had excellent glycemic control, with an HbA1c of 6.4% (47 mmol/mol), with 42 out of 46 (91%) patients not on insulin treatment.

CONCLUSIONS
At diagnosis of pediatric diabetes, absence of all islet autoantibodies and modest hyperglycemia (HbA1c &lt;7.5% [58 mmol/mol]) should result in testing for GCK, HNF1A, and HNF4A MODY. Testing all 12% patients negative for four islet autoantibodies is an effective strategy for not missing MODY but will result in a lower detection rate. Identifying MODY results in excellent long-term glycemic control without insulin.

Abstract
The yellow-feather broiler is a popular poultry breed in Asia, particularly in China. In this study, we performed RNA-seq analysis to identify differentially expressed genes (deGs) in the liver of yellow-feather broilers that had been subjected to acute heat stress treatment (38±1°C for 4 h, recovery 2 h) and determine the response of the liver to high temperature and its effects on yellow-feather broiler physiology. We found that the cloacal temperature and respiratory rate of yellow-feather chickens were significantly increased immediately after the initiation of acute heat stress (38°c) treatment. And after recovery for 2 h, there was no difference in the cloacal temperature and respiratory rate between the acute heat stress and control groups. A total of 834 DEGs were observed in response to heat stress by RNA-seq. Almost half of the DEGs were involved in the lipid and energy metabolism, including fatty acid metabolism (ACOX1, ACACA, ACSL1, ACSL6, ACAA1, ACAA2, HADHB, and FASN) and propanoate metabolism (ACSS2, ALDH2, ACACA, DLAT, ALDH7A1, MDH1, ME1, ABAT, SUCLG2, and ACSS3). Our findings provide the context for RNA-seq studies in the liver of yellow-feather chickens and suggest that the liver of yellow-feather broilers has the lipid and energy metabolism physiological mechanisms activated in response to heat stress.
Effects of Microalgae Species on In Vitro Rumen Fermentation Pattern and Methane Production
Authors: Sucu Ekin 
Published: November 2019

Abstract
This experiment was conducted to establish the effects of two types of microalgae [Chlorella vulgaris (AI), C. variabilis (AII) and their combination (AI+AII)] with two substrates (wheat and corn silages) on rumen fermentation, gas and methane production. To each substrate, one of 3 algae treatment was supplemented at 0% and 25% of the total incubated dry matter. A series of 5 measurement points (3, 6, 12, 24 and 48 h) were completed and the gas production was monitored. The proximate and mineral composition of microalgae and substrates were examined. At 48 h incubation rumen fermentation variables and CH4 production were also assessed. When compared with wheat silage, corn silage caused an increase in gas production (P<0.05). Ruminal gas production decreased in the algae groups when compared to the controls (0% algae, wheat and corn silages, P<0.05). Among algae, C. vulgaris had the strongest effect, decreasing gas production by 34%. Among algae, the total volatile fatty acids (VFA) and CH4 production were found to be lower in C. variabilis (P<0.001). Ammonia-N increased with the algae inclusion (P<0.05). But, the ruminal gas production, pH, acetate, the total VFA, CH4 and rumen fermentation efficiency were not affected by the substrate and algae interaction (P>0.05). The propionate was the highest (P<0.05) for corn silage when incubated with C. vulgaris. Ruminal butyrate was the lowest for the wheat silage when incubated with the mixture of algae (P<0.05). The NH3-N was the highest in corn silage when incubated with all algae types (P<0.05). Careful selection and combination of substrate and algae may positively manipulate rumen fermentation and may inhibit CH4 production. Further research is needed to validate these results in vivo.
Myosin Heavy Chain Composition, Rate of Dystrophin and Integrin Degradation and Meat Quality of Pig Longissimus thoracis and psoas major Muscles During Postmortem Aging
Authors: Wojtysiak Dorota 
Published: November 2019

Abstract
This study evaluated myosin heavy chain composition and the effect of aging time (45 min, 24 h, 96 h and 168 h) on meat quality parameters and dystrophin and integrin degradation pattern in longissimus thoracis and psoas major muscles of 24 Polish Landrace fatteners slaughtered at 100 kg body weight. It was found that m. longissimus thoracis had a greater percentage of MyHC-IIB (P≤0.05) and a significantly lower percentage of type I and IIA/IIX (P≤0.05) compared with the m. psoas major. Moreover, psoas major muscle had significantly higher (P≤0.05) pH45, pH24 and lower drip loss values for 45 min to 24 h, 45 min to 96 h and 45 min to 168 h than m. longissimus thoracis. Muscle type also had a significant effect on the rate of dystrophin and integrin degradation postmortem, which were significantly (P≤0.05) more rapidly degraded in the m. longissimus thoracis compared to the m. psoas major. It is concluded from the obtained results that the muscles with a greater percentage of MyHC-IIB show lower pH values, which translates into more rapid rate of integrin and dystrophin degradation. Ultimately, this may contribute to higher drip loss values during refrigerated storage.
Quality of Meat from Female Fallow Deer (Dama Dama) and Roe Deer (Capreolus Capreolus) Hunted in Serbia
Authors: Ivanović Snežana , Pisinov Boris , Pavlović Marija , Pavlović Ivan 
Published: November 2019

Abstract
Deer meat is a high quality and valuable food for human consumption. It has high nutritive value because of its high protein and heme iron content, and low levels of fats and saturated fatty acids. The aim of this study was to examine the quality parameters of meat from fallow deer and roe deer that were hunted in Serbia. Parameters studied were live weight, carcass weight, chemical composition of meat, color, fatty acid content of meat, volatile compounds, and sensory characteristics. The results obtained show no significant difference in the chemical composition of these two species of deer meat, but there were differences regarding fatty acid content, volatile compounds, color and sensory properties of meat. The ratios of polyunsaturated to saturated fatty acids in the deer meat ranged from 0.387 to 0.556. The results suggest that deer species has a significant impact on the fatty acid profile and content of volatile compounds of deer meat.

Published: November 2019

Abstract
A method of phase GNSS measurement control is described. The method is based on comparison of geometric range increments which are calculated using measurement data and approximate receiver coordinates and satellite navigation message position taking into account troposphere and ionosphere correction increments. Applicability of moving average for phase GNSS measurement control to detect the cycle slips and outliers is demonstrated. Test results of cycle slip detecting in phase measurements made by the receiver with high stability frequency oscillator are provided.
Multiple-linear regression to best-estimate of gravity parameters related to simple geometrical shaped structures
Authors: Tlas Mohammed , Asfahani Jamal 
Published: November 2019

Abstract
A new interpretative approach is proposed to best-estimate of gravity parameters related to simple geometrical shaped structures such as a semi-infinite vertical cylinder, an infinite horizontal cylinder, and a sphere like structures. The proposed technique is based on the multiple-linear regression oriented towards estimating the model parameters, e.g., the depth from the surface to the center of the buried structure (sphere or infinite horizontal cylinder) or the depth from the surface to the top of the buried object (semi-infinite vertical cylinder), the amplitude coefficient, and the horizontal location from residual gravity anomaly profile. The validity of the proposed approach is firstly demonstrated through testing different synthetic data set corrupted and contaminated by a white Gaussian random noise level. The theoretical synthetic obtained results obviously show that the estimated parameters values, derived by the proposed technique are close to the assumed true parameters values. This approach is applied on five real field residual gravity anomalies taken from Cuba, Sweden, Iran, USA, and Germany, where the efficacy of this new approach is consequently proven. A comparable and acceptable agreement is noticed between the results derived by this proposed approach and those obtained from the real field data information.
Update of the erosive rain factor in Slovakia using data from the period 1961–2009
Authors: Onderka Milan , Pecho Jozef 
Published: November 2019

Abstract
An update of the rainfall erosivity factor (R-factor) estimated for 95 locations throughout the entire territory of Slovakia is presented in this paper. We analyzed rainfall time series with 1-minute resolution provided by the Slovak Hydrometeorological Institute. The data cover the period 1961–2009. The rain gauges are located at altitudes ranging from 97 m a.s.l. up to 1322 m a.s.l. and cover the broadest possible range of geographic regions and climatic conditions in Slovakia with reliable rainfall measurements. First, rainfall episodes were isolated by applying the fundamental rule that two subsequent rains are separated by at least six hours of no rainfall. A total of 116,710 rainfall events were identified and analyzed. A rainfall event was classified as erosive if the two following criteria were satisfied: the maximum 15-minute intensity 6.25 mm (i.e. 25 mm hr−1, as originally used in the U.S.L.E. model, and/or rainfall depth was greater than 12.5 mm. The presented estimates of R-factor are based on 18,467 identified erosive rainfall events. Furthermore, the minimum length of rainfall record necessary for reliable estimates of R-factor has been estimated by spectral analysis. The Lomb-Scargle periodogram identified periodic behavior of the total kinetic rainfall energy and rainfall 15-minute intensities. We suggest that these periodicities are attributable mainly to the 11-year Sun spot cycle, the 18.6-year Luni-Solar cycle, and their higher harmonics. The spectral analysis also revealed that in order to capture the temporal variability the minimum length of time-series in calculating R-factors is 14–15 years. We estimate that the long-term mean annual R-factor in Slovakia ranges from 34.8 MJ ha−1 cm hr−1 (at Gabčíkovo station) to 138 MJ ha−1 cm hr−1 (at Tatranská Javorina station). The median value of the mean annual R-factors for the whole country is 71.13 MJ ha−1 cm hr−1. To our best knowledge, the erosive rain factor has not been updated in Slovakia since the earlier work of Mišík in 1990. This paper is thus an update of the R-factors in Slovakia.

Published: November 2019

Abstract
In the era of Industry 4.0, coal companies began to reach for new innovative technologies that increase work safety and their possible use affects the economic improvement of companies. One of them is to equip a powered roof support section with an electrohydraulic control system with a monitoring system that tracks operating parameters. The development of a monitoring system for a powered roof support is a key investment in new longwall complexes. It allows rapid diagnostics of status of the support. Currently used system designed to control the powered roof support are based on blocks of manually controlled distributors. The pilot control is currently the leading control that properly functions in all conditions, allowing to adapt to the requirements resulting from the construction of the section. A number of tests and analyses must be conducted prior to introducing the new control based on an innovative approach into operation. The basic research has focused on identifying the user interface that will potentially be the solution for the entire system. The user has defined how the driver should look like and how it will be operated and maintained. The results of the first series of tests on the elements of an innovative electronic control system of the powered roof support enabled to develop a prototype version. The assumptions for the system were verified during the conducted development studies. The article presents preliminary results of development research for devices included in the innovative control system of the powered roof support.
