Authors: Arumningtyas Restu Maharany , Triono Agung , Sutomo Retno
Published: March 2021

Background Sleep disturbances can lead to many health problems in school-aged children, including hypertension and obesity. However, a lack of consensus about the etiology of these conditions is due to conflicting reports on the possible effects of sleep disturbances.

Objective To assess for possible associations between sleep disturbances and blood pressure as well as body mass index in school-aged children.

Methods This cross-sectional study involved primary school children in the 4th-5th grades. Subjects’ blood pressure, body weight, and body height were measured and their parents completed the Sleep Disturbances Scale for Children (SDSC) questionnaire.

Results Of the 816 children enrolled, 503 (61.6%) children had sleep disturbances. The most common type of sleep disturbance was initiating and maintaining sleep. Bivariate analysis revealed a significantly increased risk of hypertension among subjects with sleep disturbances (PR 15.06; 95%CI 8.13 to 27.90) and increased risk of obesity (PR 22.65; 95%CI 12.28 to 41.78).

Conclusion The most common type of sleep disturbance is initiating and maintaining sleep. Sleep disturbances are significantly associated with hypertension and obesity in children.

Assessing the Rate of Child Maintenance (Financial Support) from a Shariah Perspective: the Case of Malaysia
Authors: Ahmad Bahiyah , Hj. Azahari Raihanah , Ab Rahman Asmak , Abdul Wahab Mazni
Published: March 2021

Shariah mandates the criteria of kifāyah and ma’rūf in assessing maintenance for wives and children; however, these criteria currently require assesment and evaluation as maintenance is mostly influenced by society’s practices and by socioeconomic status. Consequently, Malaysia’s Islamic Family Law (Federal Territory) Act 1984 presribes that the maintenance assesment for wives and children must be based on the means (ma’rūf)  and needs (kifāyah) of the parties. However, this provision is too general and there is no clear explanation of what constitutes these criteria for the parties. This provision has troubled some parties as it leaves the determination of the maintenance rate to a judge’s discretion regarding both criteria. This study, with a methodology of content analysis and in-depth interviews, determines an assessment formula for both criteria in assessing child maintenance. Hukum Islam mensyaratkan dua kriteria dalam pemberian nafkah istri dan anak yaitu kifāyah dan ma’rūf. Namun kriteria tersebut saat ini perlu ditinjau dan evaluasi lagi sesuai dengan praktik masyarakat serta keadaan social ekonomi saat ini. Seperti yang terdapat dalam hukum perundangan keluarga Islam Malaysia tahun 1984 yang menyatakan bahwa ma’rūf dan kifāyah menjadi syarat utama pemberian nafkah istri dan anak. Bagaimanapun penjelasan kriteria tersebut masih terlalu umum dan kurang jelas. Hal ini juga menyisakan beberapa persoalan akibat keputusan pengadilan yang mendasarkan pada kedua kriteria tersebut. Dengan menggunakan pendekatan analisis isi dan wawancara mendalam, kajian ini menguatkan penilaian kedua kriteria tersebut.
Arte, fenomenología y cuerpo femenino
Authors: Cely Á. Flor Emilce
Published: March 2021

Este artículo presenta dos maneras en que se relacionan el arte y la fenomenología. Por un lado, el aire de familia que hay entre la fenomenología y los logros del arte visual moderno en relación con una nueva manera de entender nuestro encuentro visual con el mundo y las ganancias a nivel experiencial que se derivan del mismo. Y, en segundo lugar, las lecciones que podemos extraer de los grandes artistas creadores y revolucionarios para conectarnos con nuestra experiencia, para volver a encontrarnos con nosotros mismos a partir de las nuevas maneras de ver que nos legaron. Se explorará en este sentido la relación arte/fenomenología con respecto al cuerpo, haciendo el contraste con la perspectiva científica del mismo, así como un análisis de la mirada artística y científica sobre el cuerpo de las mujeres a finales del siglo XIX y comienzos del XX.
Condición colonial y colonizadora de las artes en la heterarquía colonial del poder
Authors: Gómez Pedro Pablo
Published: March 2021

Cuando en el año 2007 iniciábamos la aventura de crear una nueva revista denomi-nada Calle14: revista de investigación en el campo del arte, éramos conscientes de que el campo de las artes nunca había gozado de una completa autonomía y, por el contrario, para bien o para mal, ha estado atravesado y condicionado por las fuerzas de otros campos sociales y por jerarquías en las que se manifiesta históricamente el poder global. Al mismo tiempo, se empezaba a hablar sobre las potencialidades epistémicas, éticas y políticas de la creación artística, y la necesidad de establecer un diálogo en nuevos términos con la investigación científica, sus metodologías, sus lógicas y hasta sus formatos de elaboración de proyectos, así como con los criterios estatales para la valoración de la producción artística. En ese contexto, desde varias Facultades de Artes, reunidas desde el año 2004 en la Asociación Colombiana de Facultades de Artes, ACOFARTES, se empezaba a adoptar la investigación-creación como la categoría que haría posible el mencionado diálogo con las ciencias y, al mismo tiempo, el desenganche epistémico de las mismas, para re-posicionar las artes como modo legítimo de creación de conocimientos sensibles.

Published: March 2021

The impact pressure induced by slamming can imply physical damage on a ship. The high probability of the slamming impact is on the bow part in the actual sea state. In this present study, the slamming induced pressure on the bow flare of a ship have been investigated through the experiment. The experiment was schemed by the dropping test based on free-falling body in the wave tank, wherein the bow of the ship model was inclined in several impact angles 0° to 30° to the free-water surface. To measure slamming impact pressure acting on the bow flare, the piezoelectric sensors S1, S2, S3, S4 were attached to the bow section and installed on a computer. As the obtained results, the impact pressure on bow flare occurred in a short time duration caused by slamming. The discrepancy of the peak impact pressure between ship model weight of 2.42 kg and 7.29 kg for the impact angle 0° is 70.36% S1, 69.52% S2, 68.97% S3, and 68.34% S4. For the relative impact angle of 30°, the discrepancy is 67.02% S1, 65.73% S2, 58.51% S3, and 48.21% S4. The tendency of the peak pressure coefficient at the sequenced impact points S1, S2, S3, S4 is similar for all impact angles 0°, 10°, 20°, and 30°. The peak pressure coefficient due to the full load condition is highest in the nearest bottom part, and the peak pressure coefficients due to the lightship condition highest in the nearest bottom part caused by the small impact angle.

Backgrounds: Root surface caries is a significant oral public health problem among humans' due to improvements in health care, long life expectancy, and increasing demand to maintain oral health. The objective of this study was to determine the prevalence of root caries in subjects in Erbil city and its relation to various risk factors. Subjects and methods: The study was conducted in twelve primary health care centers in different directions of the city. A total of 2600 subjects (1352 males and 1248 females) attending these centers aged 25-64 years old were examined. The following clinical parameters were evaluated: root caries index, plaque index, gingival index, unstimulated salivary flow rate, other related factors as behavioral habits, oral practices, and educational level were assessed by means of multiple choice questionnaires by direct interview. Results: The results of this study showed that the prevalence of root caries was (22.3%) and the mean value of root caries was (33.650±16.504) in the whole sample with statistically significant age differences of both. Males were more prevalent in root surface caries than females with significant differences. Results showed that the mandibular teeth were more affected than the maxillary teeth, and that mandibular first molars were the mostly affected teeth by root caries. Prevalence of root caries was significantly associated with these risk factors: gingival index, plaque index, unstimulated salivary flow rate, educational level, wearing removable partial dentures, frequency of snacks, tooth brushing and frequency of tooth brushing, systemic disease and use of medication, while the results showed no association between prevalence of root caries and smoking. Conclusions: The results indicate that adults and older aged individuals in Erbil city have a high prevalence of root caries and high experience of root caries as expressed by root caries index and the prevalence of root caries was associates with these risk factors: Gingival index, Plaque index, unstimulated salivary flow rate, educational level, wearing removable partial dentures, frequency of snacks, tooth brushing and frequency of tooth brushing, systemic disease and use of medication while there was no association with smoking.

Histomorphometric analysis of goat uterine tissue on in vitro exposure with ovarian hormones and mifepristone
Authors: Sharma R. K. , Singh P.
Published: March 2021

Uterus, the largest reproductive tract organ in female mammals, is the site of implantation of fertilised egg and foetus development. Uterus is a dynamic reproductive organ; its morphology alters with reproductive phase and steroidal cues. The aim of the present study was to assess the effects of progesterone (P4), estrogen (E2) and antiprogestogen i.e., mifepristone on goat’s uterine histoarchitecture in in vitro short term culture. Uterine tissue slices were cultured in the presence of E2, P4 and mifepristone at the dose of 10–9 M, 10–7 M and 10–6 M respectively for 24 hours. Uter-ine morphology of E2- and P4-treated groups did not reveal marked changes from that of control group. Mifepristone treatment caused conspicuous changes in uterine histoarchitecture, led to congested endometrium, regressed uterine glands and constricted blood vessels. The changes ob-served in morphometry after E2 and P4 exposure included increased uterine gland diameter (47.00 and 45.95 µm respectively) and glandular epithelial cell height (18.37 and 17.43 µm respectively) while the mifepristone treatment resulted in significant reduction of gland diameter (34.95 µm) as well as epithelium height (14.25 µm) as compared to those in control group (39.9 and 15.56 µm respectively). These morphometrical changes revealed prominent regressive changes in anti-progestin treated group while E2 and P4 showed prolific effects in in vitro culture. Thus it is envis-aged that E2 and P4 induced characteristic progressive changes in the histologic structure especially in endometrial glands of the goat uterus while anti-steroidogenic formulation i.e. mifepristone severely reduced the normal histoarchitecture of the uterus which is a prerequisite for implanta-tion.
Range extension of Thomasomys princeps (Thomas, 1895) (Rodentia, Sigmodontinae) and first record in Venezuela

Thomasomys princeps (Thomas, 1895) is a large, sigmodontine rat and a member of the “aureus” group of the highly diverse genus Thomasomys. This species is only known from the Cordillera Oriental, Colombia; however, based on a recent examination of specimens of Thomasomys from Venezuela, I report the first record of T. princeps from Venezuela, in the Páramo del Tamá near the Colombian border. This record extends the distributional range of the species by 360 km northeast, representing the northernmost record of the species and of the “aureus” group.
An Ass in a Lion’s Skin
Authors: Doane Sébastien
Published: March 2021

The book of Genesis gives two opposing portraits of Judah’s masculinity. On the one hand, he is shown as the leader of Jacob’s sons, and on the other he is ridiculed by his daughter-in-law. Is Judah an ass in a lion’s skin? This article explores Judah’s antithetical masculinities as examples of the inherently unstable nature of gender construction. Although Judah is only the fourth son of Jacob, he is expressly depicted in Genesis as assuming a leadership role in relation to his brothers, including speaking up against killing Joseph, negotiating with his father regarding Joseph’s demand that Benjamin be brought down to Egypt, and pleading with Joseph for Benjamin’s life. In Genesis 49: 8–12, Judah receives the most favourable treatment of all Jacob’s sons. The blessing of Jacob from his deathbed portrays Judah’s hegemonic masculinity at its finest. However, in Genesis 38, Judah’s masculine performance far from ideal biblical masculinity. Not only does Judah lack persuasiveness when he accuses Tamar, but she is able to persuade him that his own actions were wrong. Judah is deceived, specifically deceived by a woman. The shame he wants to attribute to Tamar rebounds on himself. In the end, he acknowledges himself to be less righteous than Tamar (Gen 38: 26). The episode as a whole reveals that Judah does not have control of his family. Genesis 38 clearly subverts Judah’s hegemonic masculinity. What are the rhetorical effects of this subversion of Judah’s hegemonic gender construction? Jacob speaks of Judah as a lion, but in Genesis 38 he seems to have been portrayed in the role of the ass.

Forecasting US Inflation in Real Time
Authors: Fulton Chad , Hubrich Kirstin
Published: March 2021

We perform a real-time forecasting exercise for US inflation, investigating whether and how additional information--additional macroeconomic variables, expert judgment, or forecast combination--can improve forecast accuracy and robustness. In our analysis we consider the pre-pandemic period including the Global Financial Crisis and the following expansion--the longest on record--featuring unemployment that fell to a rate not seen for nearly sixty years. Distinguishing features of our study include the use of published Federal Reserve Board staff forecasts contained in Tealbooks and a focus on forecasting performance before, during, and after the Global Financial Crisis, with relevance also for the current crisis and beyond. We find that while simple models remain hard to beat, the additional information that we consider can improve forecasts, especially in the post-crisis period. Our results show that (1) forecast combination approaches improve forecast accuracy over simpler models and robustify against bad forecasts, a particularly relevant feature in the current environment; (2) aggregating forecasts of inflation components can improve performance compared to forecasting the aggregate directly; (3) judgmental forecasts, which likely incorporate larger and more timely datasets, provide improved forecasts at short horizons.
Editorial vs Political Commentary: Establishment of the Genres in Siberian Regional Press (a Case Study of Minusinsk Newspaper Texts in the Period of 1906-1917)
Authors: Kostyakova Julia
Published: March 2021

The article deals with editorial and political commentary as journalistic genres, reveals their typological features, similarities and differences. The author gives reasons for saving these genres and considering them as those belonging to the group of analytical genres, since their basis is the logical analysis of real events, phenomena or facts. The author studies the historical transformation of editorial and political commentary in the pre-revolutionary, Soviet and post-Soviet periods, and determines the causes of the changes. The author infers that currently, editorial is best developing in the context of columnism, whereas political commentary is most successful in the Internet. This foregrounds the study of both current state and historical conditions for the development of these genres, especially in Siberian regional press at the establishment stage in the early XX century. The analysis of papers issued consecutively from 1906 to 1917 in Minusinsk, the central town of Yenisei province, shows the main trends in the change of the content of these types of newspaper text. An editorial containing comments on political issues was an indicator of particular quality of the newspaper, since the readers were provided with the editors or leading journalists reasoned point of view on the events and phenomena of those days. The choice of the topic and the content of the coverage were determines by the censorship and historical conditions, availability of information sources and the writers experience. Despite similarities in the topic and content, editorial and political commentary had different headlines and references to the author. Moreover, in the Bolshevists press, which became legalized in the time of the February Revolution, editorial was used as a means of agitation, and thus set up the tradition for the Soviet press.

An adaptive mixed finite element method using the Lagrange multiplier technique is used to solve elliptic problems with delta Dirac source terms. The problem arises in the use of Chow-Anderssen linear functional methodology to recover coefficients locally in parameter estimation of an elliptic equation from a point-wise measurement. In this article, we used a posterior error estimator based on averaging technique as refinement indicators to produce a cycle of mesh adaptation, which is experimentally shown to capture singularity phenomena. Our numerical results showed that the adaptive refinement process successfully refines elements around the center of the source terms. The results also showed that the global error estimation is better than uniform refinement process in terms of computation time.

Automotive racing is one of the favorite sports of human being. There have been many developments in past decades by car engineers to improve the performance of the engine and increase the aerodynamic efficiency of the race cars to achieve a better lap time and get a better placement safely. One of the ways to improve the aerodynamic performance of a race car is to use rear spoilers. This study by using ANSYS FLUENT numerically investigated the effect of the spoiler shape and setting angle on the aerodynamic characteristics of a race car and then it was validated by conducting wind tunnel experiment. Lift and drag coefficient of NACA0012, NACA4412, and S1223 are determined in Reynold’s number of 2×105 as an airfoil and as spoiler on ERC model which is a conceptual car model inspired by Porsche 911. It was found that ERC model with spoiler would have better aerodynamic efficiency compared to ERC model without spoiler. Also, S1223 at -6 degrees was identified as the optimized configuration as it generates the highest downforce. Even though the drag coefficient at this setting angle is slightly higher, but in terms of stability and handling IT is at its best. Overall, this study would help car manufacturers, for racing and commercial purposes, to have a better insight into the effect of spoiler configuration on the aerodynamic performance of cars. Hence, the stability, handling, and efficiency of the cars can be further improved by selecting the suitable spoiler configuration.
The Effects of Surfactant on the Evolution of a Thin Film under a Moving Liquid Drop

Published: March 2021

The effect of surfactant on the thickness of a thin film bounded by a solid surface and a moving liquid drop was investigated. We proposed a model so that parameters from the liquid drop can be stated in a parameter that acts as normal pressure to the thin film. Using the lubrication approximation, the model was reduced to a set of nonlinear partial differential equations in terms of the film thickness and surfactant concentration. Since we were interested in the role of the surfactant in lifting up the drop, we assumed that the density of the drop is higher than the density of the thin film. Numerically, the results show that the presence of the surfactant tends to delay the decrease of the film thickness insignificantly. However, when the surfactant was added into the system, it tends to significantly increase the film thickness for a certain range value of the normal pressure.

A turbidity telemetry system for COVID-19 pandemic situations using nRF24L01+transceiver and SEN0189 water turbidity sensor-based microcontroller has been successfuly  developed.. The method used to characterize the sensor is by comparing sensor output voltages with the value of water turbidity. Turbid water used was created by adding distilled water with a concentration of sediment obtained from the filtered sediment with less than 60 μm in diameter. Data transmission performance for various transmit power was done by calculating the error percentages by comparing the number of messages sent by transmitter and received by receiver. The transmit power settings were 0, -6, -12, and 18 dBm and variations in the distance of data transmission from 10 to 80 m. The test results show that the water turbidity sensor has a good measurement range in measuring turbidity of water from 1.873 to 3500 NTU. Higher concentrations of sediment and turbidity of the water made the sensor output voltage decrease. There was a decrease in output voltage in the value, namely -0.0006 in turbidity sensor sensitivity. The results also show an increase in error percentages as the distance of data transmission increases, while the bigger the transmit power is used for data transmission, the smaller the percentage of errors occurs.

Natural gas is conventionally transported in its liquid form or Liquid Natural Gas (LNG). It is then transported using cryogenic insulated LNG tankers. At receiving terminals, LNG is regasified prior to distributing it through gas distribution system. Seawater has been used as the heat source, which leads to vast amount of cold energy discarded into the water. This work presents the use of LNG cold energy around Melaka Refining Company (MRC). The cold energy is utilized in power generation, propylene refrigeration cycle, and air separation plants. These systems are designed and simulated using a commercial process simulation software. Capital cost (CAPEX) function and revenues of each system are further developed as a function of LNG flowrates. These developed correlations are then used in an optimization problem to seek for the most profitable scenario. The results show that utilizing LNG for air separation unit yields the highest profit compared to power generation and refrigeration plants.

This paper proposed a grape drying machine using computer vision and Multi-layer Perceptron (MLP) method. Computer vision is for taking grapes’ image on conveyor, whereas MLP is for controlling grape drying machine and classifying its output. To evaluate the proposed, a kind of grapes are put on conveyor of the machine and their images are taken every two min. Some parameters of MLP to control the drying machine includes dried grape, temperature, grape area, motor position, and motion speed. Those parameters are to adjust an appropriate MLP’s output, including motion control and heater control. Two different temperatures are employed on the machine, including 60 and 75°C. The results showed that the grape could be dried with similar area 3800 pixel at the 770th min using temperature 60°C and at the 410th min using temperature 75°C.  Comparing between them, the similar ratio could also be achieved at 0.64 with different time 360 min. Indeed, the temperature setting at 75°C resulted faster drying performance.

The unique structure of Magnéli phases TiOx renders them effective for the electrochemical applications. This work demonstrates a synthesis of carbon-coated Magnéli phases TiOx (TiOx@C) nanoparticles from 3-aminophenol and rutile titania (TiO2) nanoparticles as a support for platinum (Pt) electrocatalyst. 3-aminophenol was polymerized and carbonized on the surface of TiO2 nanoparticles respectively in a microwave hydrothermal reactor and a tubular furnace. Reduction of the carbon-coated TiO2 (TiO2@C) into TiOx@C was performed in hydrogen atmosphere at 800-1050 °C. The carbon coating effectively prevented TiO2 nanoparticles from sintering, resulted in TiOx@C sizes from 50 to 100 nm. Single-phase Ti4O7 core, which has the highest theoretical electrical conductivity among the Magnéli phases, was obtained from reduction of TiO2@C at 1000 °C. for 10 min C/Ti4O7-supported Pt exhibited an electrochemical surface area of 46 m2 mgPt-1 at 15% Pt loading, slightly higher than that reported for commercial TKK electrocatalyst with 20% Pt loading (44.13 m2 mgPt-1).
