Authors: Sitohang Mangantar
Published: December 2019

This research attempts to describe Assimilation Consonant Sound Process Resemblances found in English and Batak Language, one of the local languages existing in Indonesia seen from Consonant Classifications Angles. Showing and describing the resemblance or similarity of assimilation process of the two languages can enrich our insight about this reality or process. Their resemblance discussed here is focused on utterance or oral communication/spoken language, precisely in accent level.  As popularly known, in English, it is not always easy to know what sounds the letters stand for. The same letters often have some different sound symbols or patterns depending on their boundaries or environment. There are forty four (44) English sound symbols as the representation of 26 English letters, while in Batak language (especially Batak language variety/dialect in Samosir, from the 26 letters known, their sound symbols are also twenty six, more or less the same as the sound symbols  found in Bahasa Indonesia. So in English, every written letter always reminds us of corresponding sound symbols when speaking, while in Batak Language those don’t exist. But what is unique and interesting the researcher always has in mind, although English and Batak Languages do have huge difference if seen from Linguistics, but at the same time they do have certain resemblances which can be shown/described from English assimilation process

Berbagai upaya telah dilakukan untuk dapat menurunkan AKI, AKB dan AKBAI, namun hingga saat ini angka kematian ibu masih tinggi, hasil Supas 2015, AKI sebesar 305/100.000 kelahiran hidup, angka kematian anak 20/1000 kelahiran hidup pada SDKI 2007 menjadi 19/1000 kelahiran hidup. Berbagai upaya telah dilakukan guna mencapai tujuan tersebut dengan mengoptimalkan pemanfaatan buku KIA dalam menunjang kesehatan ibu dan anak melalui pemberdayaan keluarga dan masyarakat yang telH diakui keefektifannya oleh banyak negara. Secara garis besar, buku KIA di Indonesia mencakup 2 elemen penting, yaitu: alat pencatatan dan sebagai mendia informasi / materi pendidikan berbasis rumah. Namun hasil monitoring evaluasi menunjukan 83% ibu lebih menyebutkan buku KIA sebagai catatan kesehatan ibu (83%) dan catatan kesehatan anak (68%) daripada sebagai informasi penting cara memelihara dan merawat kesehatan ibu (39%) dan kesehatan anak (52%) . Kelengkapan pengisian buku KIA masih rendah terutama pada bagian tumbuh kembang anak. Data diatas menunjukkan bahwa buku KIA cukup efektif dalam merubah perilaku ibu hamil dan ibu balita untuk lebih peduli terhadap kesehatan ibu dan balitanya. Namun buku KIA belum secara optimal digunakan sebagai mendia informasi, sehingga kepemilikan buku KIA belum berdampang pada peningkatan pengetahuan ibu tentang kesehatan anak. Kelurahan Mulyasari terdapat 11 posyandu, salah satu posyandu bertempat di RW 11 berada di wilayah kerja UPTD Puskesmas Tamansari yang mana sebanyak 6 kader belum pernah mendapatkan pendampingan tentang pemantauan tumbuh kembang Balita. Metode yang tepat salah satunya adalah dengan melakukan pendampingan kader untuk meningkatkan keterampilan tumbuh kembang.

Authors: Iqbal Mian Rashid
Published: December 2019

Background: Malocclusion is recognized as one of the most common dental problems affecting the young adults and adolescence globally. Oral functions and facial aesthetics are influenced by the severity of malocclusion and it's of great concern to the individual, their families and health authorities as well. Most of the reported studies for Kingdom of Saudi Arabia are from the eastern, southern and central region. To the best of our knowledge no data is available for the northern region of Hail; therefore the aim of this study was to determine the prevalence of malocclusion among the population of Hail city.

Methodology: Descriptive study having a cross sectional study, convenient sample size of 504 Saudi populations between the age group of 13 – 50 years. Informed consent was taken from the participants before conducting the examination, parents’ consent was sought for children. Malocclusion was recorded as described by WHO, oral health Survey, and basic methods. Each subject was examined for the type of malocclusion according to Angle’s classification.

Results: Most predominant malocclusion was Angle’s Class I 41.7% in females and 26.2% in males.15.4% males and 23.3% females had excessive overjet (>2mm) compared to 38% males and (24.3%) females who had reduced overjet (2mm) whereas 32.3% males and 20.5% females had reduced overbite (<1 mm), anterior cross bite was reported in 5.6%males and (1.3%) females and open bite in 5.6% males and 5.5 % females.

Conclusion: Within the limitations of this study, the prevalence of malocclusion in Hail region of Saudi Arabia is comparable with that of other regional studies.Most of the study participants exhibited Angles class I occlusal features with normal overjet and overbite.
Changing Pattern of Intra-Alveolar Extraction in the Southwest Nigeria
Authors: A. Adelusi Emmanuel
Published: December 2019

Introduction: Though changing patterns of tooth extraction have been reported in the literature which included the age, gender, tooth type and indications for extraction, there is still paucity of studies that have examined the variation and changes in the pattern of tooth extraction over a period of time in a given nation. We therefore accessed the pattern and indications of tooth loss in the patients who presented at oral surgery clinic for intra-alveolar tooth extraction over a twelve month period.
Methods: This is a prospective cohort study of adult patients tooth extraction between September 2015 and August 2016. Patients’ demographic and clinical data were collected with a structured questionnaire. Data were analyzed using statistical package for social sciences (SPSS) version 23.0. Variables were subjected to Pearson’s chi-square test and P <0.05 was considered statistically significant.
Results: A total of 240 adults age range between 18 to 75 years of age with mean age of 36.64 years were included in the analysis. Maxillary teeth (231) and mandibular teeth (326) were extracted in 203 and 263 patients respectively. Caries and its sequelae, 223(93%) were the predominant indication for tooth extractions. Lower second molar (25%), and upper third molar (20%) had the highest frequencies. More female (126, 52.5%) than male (114, 47.5%) had extraction done, the difference is however not statistically significant (X2 =1.67, P Value = 0.195)
Conclusions: Dental caries and its sequelae are the most frequent cause of tooth extraction. Tooth extraction was more in Patients in the fourth decade as well as in the Female gender, even though the difference between male and female is not statistically significant. And there is increased in number of male who had extraction done compared to what obtained in the past decades. Left side of the mouth appeared to be more affected.
Nyer Zet-Ractor – Innovative Multifunctional Concept of Retraction
Authors: Firdose Nyer
Published: December 2019

Post-operative pain and swelling is one of the common complications following mandibular third molar surgery leading to very disturbing days immediately following third molar extraction. On considering the impact of such post-operative sequelae on the patient’s quality of life, it is necessary to exercise preventive measures to minimize the occurrence of such complications / untoward events. Although many retractors are already in application for retraction of tissues during the third molar extraction, this manuscript describes an innovative multifunctional concept “Nyer Zet-ractor” designed for retraction and isolation without limiting the accessibility to the surgical area in mandibular third molar surgery.

The “Nyer Zet-ractor” described in this manuscript is an innovative device which provides the advantages like clear access, continuous visibility and excellent isolation of the surgical site unlike conventional retractors with minimal retractive forces thereby reducing post-operative pain and swelling. Nyer Zet-ractor implements a multifunctional concept of retraction making it an efficient, easy to use, and exerts a known and finite amount of force, thereby avoiding tissue damage.
An Unexpected Complication after Use of Pedicled Buccal Fat Pad for Closure of Oroantral Fistulae: Emphysema
Authors: Metin Revnak
Published: December 2019

Oro-antral communication (OAC) may develop as a complication of dental extraction, trauma, infection or neoplasm. Buccal fat pad (BFP) has been increasingly used for the closure of OAC. However, some complications can be seen for pedicled buccal fad pad flap (PBFPF), such as infection, limitation in mouth opening, hematoma, and swelling. Nevertheless, there are no previousreports of subcutaneous emphysema after PBFPF. In this paper; a complication developed in the early period after use of PBFPF for closure of OAF was illustrated with special emphasis showing the strength of BFP against tension forces.

Exoplanet Imitators: A Test of Stellar Activity Behavior in Radial Velocity Signals
Authors: Nava Chantanelle , López-Morales Mercedes , Haywood Raphaëlle D. , Giles Helen A. C.
Published: December 2019

Accurately modeling effects from stellar activity is a key step in detecting radial velocity (RV) signals of low-mass and long-period exoplanets. RVs from stellar activity are dominated by magnetic active regions that move in and out of sight as the star rotates, producing signals with timescales related to the stellar rotation period. Methods to characterize RV periodograms assume that peaks from magnetic active regions will typically occur at the stellar rotation period or a related harmonic. However, with surface features unevenly spaced and evolving over time, signals from magnetic activity are not perfectly periodic, and the effectiveness of characterizing them with sine curves is unconfirmed. With a series of simulations, we perform the first test of common assumptions about signals from magnetic active regions in RV periodograms. We simulate RVs with quasi-periodic signals that account for evolution and migration of magnetic surface features. As test cases, we apply our analysis to two exoplanet hosts, Kepler-20 and K2-131. Simulating observing schedules and uncertainties of real RV surveys, we find that magnetic active regions commonly produce maximum periodogram peaks at spurious periods unrelated to the stellar rotation period: 81% and 72% of peaks, respectively, for K2-131 and Kepler-20. These unexpected peaks can potentially lead to inaccuracies in derived planet masses. We also find that these spurious peaks can sometimes survive multiple seasons of observation, imitating signals typically attributed to exoplanet companions.
Importance of Giant Impact Ejecta for Orbits of Planets Formed during the Giant Impact Era
Authors: Kobayashi Hiroshi , Isoya Kazuhide , Sato Yutaro
Published: December 2019

Terrestrial planets are believed to be formed via giant impacts of Mars-sized protoplanets. Planets formed via giant impacts have highly eccentric orbits. A swarm of planetesimals around the planets may lead to eccentricity damping for the planets via the equipartition of random energies (dynamical friction). However, dynamical friction increases eccentricities of planetesimals, resulting in high velocity collisions between planetesimals. The collisional cascade grinds planetesimals to dust until dust grains are blown out due to radiation pressure. Therefore, the total mass of planetesimals decreases due to collisional fragmentation, which weakens dynamical friction. We investigate the orbital evolution of protoplanets in a planetesimal disk, taking into account collisional fragmentation of planetesimals. For 100 km sized or smaller planetesimals, dynamical friction is insignificant for eccentricity damping of planets because of collisional fragmentation. On the other hand, giant impacts eject collisional fragments. Although the total mass of giant impact ejecta is 0.1–0.3 Earth masses, the largest impact ejecta are ∼1000 km in size. We also investigate the orbital evolution of single planets with initial eccentricities of 0.1 in a swarm of such giant impact ejecta. Although the total mass of giant impact ejecta decreases by a factor of 3 in 30 Myr, eccentricities of planets are damped down to the Earth level (∼0.01) due to interaction with giant impact ejecta. Therefore, giant impact ejecta play an important role for determination of terrestrial planet orbits.
Gamma-Ray Burst Host Galaxies: Specific Star Formation Rate versus Metallicity
Authors: Björnsson Gunnlaugur
Published: December 2019

The observed properties of long gamma-ray burst (GRB) host galaxies show them to often be of a rather low metallicity and/or of high specific star formation rate (SFR). It is not clear which of these properties is a dominant factor in determining if a galaxy will host a GRB or not. In fact there are indications, at least in the local universe, that the two may be anticorrelated and that the metallicity is the deciding parameter. Here, we consider GRB production models dependent on both quantities and show that when compared to the best available data, the respective star formation fractions appear indistinguishable out to a redshift of z ∼ 4. However, the fraction of galaxies hosting a GRB, as determined by the specific SFR, is less at tension with the observed host galaxy fraction than the corresponding metallicity determined fraction, but this conclusion is model dependent. Well established galaxy stellar mass and star formation rate functions at high redshift are crucial in breaking the apparent degeneracy between the specific rate and metallicity in GRB production probability.
Stochastic Chemical Evolution of Radioactive Isotopes with a Monte Carlo Approach
Authors: Côté Benoit , Yagüe Andrés , Világos Blanka , Lugaro Maria
Published: December 2019

Short-lived radionuclides (SLRs) with mean lives τ of a few to hundreds of Myr provide unique opportunities to probe recent nucleosynthesis events in the interstellar medium and the physical conditions in which the Sun formed. Here we quantify the uncertainty in the predicted evolution of SLRs within a parcel of interstellar gas given the stochastic nature of stellar enrichment events. We assume that an enrichment progenitor is formed at every time interval γ. For each progenitor, we randomly sample the delay time between its formation and its enrichment event, based on several delay-time distribution (DTD) functions that cover a wide range of astrophysical sites. For each set of τ, γ, and DTD functions, we follow the abundances of SLRs for 15 Gyr and repeat this process thousands of times to derive their probability distributions. For τ/γ ≳ 2, the distributions depend on the DTD function, and we provide tabulated values and analytical expressions to quantify the spread. The relative abundance uncertainty reaches a maximum of ∼60% for τ/γ = 1. For τ/γ ≲ 1, we provide the probability for the SLR abundance to carry the signature of only one enrichment event, which is greater than 50% when τ/γ ≲ 0.3. For 0.3 ≲ τ/γ ≲ 2, a small number of events contributed to the SLR abundance. This case needs to be investigated with a separate statistical method. We find that an isolation time for the birth of the Sun of roughly 9–13 Myr is consistent with the observed abundances of 60Fe, 107Pd, and 182Hf in the early solar system when assuming τ/γ ∼ 3 for these isotopes.
Spectropolarimetric Insight into Plasma Sheet Dynamics of a Solar Flare
Authors: French Ryan J. , Judge Philip G. , Matthews Sarah A. , Driel-Gesztelyi Lidia van
Published: December 2019

We examine spectropolarimetric data from the Coronal Multi-channel Polarimeter (CoMP) instrument, acquired during the evolution of the 2017 September 10 X8.2 solar flare on the western solar limb. CoMP captured linearly polarized light from two emission lines of Fe xiii at 1074.7 and 1079.8 nm, from 1.03 to 1.5 solar radii. We focus here on the hot plasma sheet lying above the bright flare loops and beneath the ejected coronal mass ejection. The polarization has a striking and coherent spatial structure, with unexpectedly small polarization aligned with the plasma sheet. By elimination, we find that small-scale magnetic field structure is needed to cause such significant depolarization, and suggest that plasmoid formation during reconnection (associated with the tearing-mode instability) creates magnetic structure on scales below instrument resolution of 6 Mm. We conclude that polarization measurements with new coronagraphs, such as the upcoming Daniel K. Inouye Solar Telescope, will further enhance our understanding of magnetic reconnection and development of turbulence in the solar corona.

O trabalho investigou o que é necessário para uma pessoa ser considerada como detentora de alto capital cultural, buscando persistências históricas, novas concepções e o papel da ciência nesse contexto. Participaram dessa pesquisa 67 graduandos. Para tanto utilizou-se um questionário dividido em três etapas que tiveram como finalidade verificar: perfil sociodemográfico dos estudantes, práticas culturais desses participantes, e o que é necessário para ser considerado uma pessoa culta. A análise foi baseada nas ideias do sociólogo Bourdieu, e foi visto que apesar de muitos autores julgarem o que foi descrito como cultura legítima nos anos 70 como desatualizado, a maioria dos entrevistados acredita que práticas culturais como ir ao teatro e dominar a língua culta nos meios acadêmicos são necessárias para uma pessoa ser considerada culta, o que corrobora a teoria Bourdieusiana. Entretanto, também foi observado novas concepções como, por exemplo, ser engajado em causas sociais e ir a congressos.

Considerando a importância das aulas experimentais e as dificuldades encontradas por professores de Química para esta prática, este estudo teve como objetivo apresentar uma abordagem experimental investigativa por meio de um método alternativo para determinação de vitamina C em suco de laranjas. Durante o trabalho, avaliou-se o teor de vitamina C em quatro espécies de laranjas comercializadas na região pelo método titulométrico de oxirredução, utilizando lugol como reagente alternativo. Os resultados mostraram-se de acordo com o Ministério da Agricultura e do Desenvolvimento, que determina um teor mínimo de 2,5 mg de vitamina C. No decorrer do artigo também apresenta-se conhecimentos históricos, sociológicos, aspectos químicos e biológicos da vitamina C, que permitem uma leitura crítica e possibilidades de contextualização com a prática experimental. Finalmente, são apresentadas possibilidades de aplicação no ensino de Química.

The Congo Basin rainforest is the second largest rainforest in the world and one of the most biodiverse regions on Earth. Nevertheless, the Congo Basin biodiversity remains to be fully mapped, with many species awaiting discovery or official description. In recent years, much effort has been put into research on shrews (Soricidae), particularly in the region around Kisangani (D.R. Congo). Shrews are opportunistic feeders that are able to forage on a large diversity of invertebrate prey and therefore play an important role in the forest ecosystem. Furthermore, as they largely depend on forest habitats and have limited dispersal capacities, shrews form an interesting model group to study biogeographic patterns in the Congo Basin.

This paper collates the efforts on shrew research from the wider region around Kisangani, in the centre of the Congo Basin. Apart from sampling information, the dataset includes morphological measures, DNA sequences and photographs. This dataset is therefore critical in the study of the taxonomy and ecology of Soricidae in the Congo Basin lowland rainforests.
Réseau, Processus, Cadre

La complexité du travail en réseau sera discutée à partir de deux situations d’enfants placés en institution éducative, ce qui suppose la collaboration avec la tutelle et les institutions de soins. Dans le premier cas, il s’agit un garçon à comportement violent, dont la situation s’améliore, finalement, il est placé en famille d’accueil. Dans la deuxième situation, c’est une fille qui relève du syndrome d’aliénation parentale : les parents sont divorcés, le père a la garde, l’enfant l’accuse d’attouchements sexuels, sans que ce soit confirmé. Le conflit entre parents se rejoue entre foyer et tutelle, par rapport à la prise en charge thérapeutique de l’enfant. Dans les deux cas, il y a un processus particulier qui sera analysé en rapport avec le cadre du réseau. Dans le premier, une finalité fut possible, dans le deuxième, il y a une décision de justice discutable, malgré des réunions de concertation. Le processus est compris par rapport au cadre transsubjectif du réseau.
API « hour » : l’Atelier projet intergénérationnel
Authors: Touboul Choukroun Valérie
Published: December 2019

Cet article transmet l’histoire et l’intérêt thérapeutique d’un atelier mémoire d’une institution gériatrique constitué par un groupe de résidents atteints d’un syndrome dit démentiel et accompagnés durant quatre années. La singularité de cet atelier consiste en la participation encadrée et suivie, sur les deux premières années de son élaboration, d’une classe d’enfants de cm1 , puis prolongée au cm2 , qui a fait figure de support de médiation et de transformation. Soutenue par une approche groupale psychanalytique, la conjonction de l’association libre et de l’écoute flottante a nourri une transmission réciproque et réenclenché le désir de s’investir, d’investir et de créer. Ce constat s’est manifesté à la fois au niveau individuel et groupal, et ce, quel que soit l’âge. Dans cet espace-temps transitionnel, ensemble, ils ont trouvé-créé, pour les uns, et retrouvé-recréé, pour d’autres, une part de mémoire singulière qui constitue cette histoire nommée api , Atelier projet intergénérationnel.
De la dépendance à l’institutionnalisation des soins de longue durée dans le grand vieillissement : perspectives psychanalytiques autour des dynamiques du passage
Authors: Racin Céline
Published: December 2019

Considérant le passage d’une hospitalisation en service de gériatrie à une institutionnalisation des soins de longue durée (au domicile ou en établissement d’hébergement) comme une expérience à risque au cours du vieillissement, l’article propose de revisiter la question de l’institutionnalisation en examinant le type de processus visé par l’aménagement des dispositifs de soins de longue durée et le travail psychique susceptible de se mobiliser à ce moment de la vie. Ce passage, dont l’article explore la valeur de rite, marque des seuils paradoxaux entre sécurité et discontinuité, qui parent cet événement d’enjeux psychiques considérables, au regard desquels la scène hospitalière produit ses propres effets de sens. La discussion menée vise à souligner la valeur trophique des supports de figuration et d’élaboration ainsi proposés par ces ritualités institutionnelles, tout comme leurs possibles effets d’assignation.
An Injectable Calcium Sulfate-Based Bone Graft Putty Using Hydroxypropylmethylcellulose as the Plasticizer

Abstract

The addition of a plasticizer to synthetic bone graft substitutes can improve handling characteristics, injectability, and the ability to uniformly fill defects. Restoration of large medullary bone defects using an injectable calcium sulfate-based putty using hydroxypropylmethylcellose as the plasticizer was compared to conventional calcium sulfate paste in a canine model. Beginning 2 weeks following implantation, serial clinical and specimen radiographs demonstrated a similar progressive resorption of the implanted materials and replacement with new bone for both the putty and paste forms of calcium sulfate. The area fraction of new bone and remaining implant material in bone defects treated with the putty were not significantly different from defects treated with conventional calcium sulfate paste after ? 3 and 26 weeks. In addition to its handling characteristics, the putty was biocompatible and as effective as conventional calcium sulfate paste in achieving substantial bony restoration of a large, critical-size bone defect.

Abstract

The use of a porous tricalcium phosphate bone void filler (Cellplex TCP, Wright Medical Technology, Ine, Arlington, Tenn) as an alternative to autograft in bone grafting was studied in benchtop, in vitro cell culture, and in vivo preclinical studies. The experimental design included material property quantification, scaffold seeding with mesenchymal stem cells, and implantation in a rabbit segmental defect model. Measured material properties denoted appropriate composition, porosity, and strengths as compared to the literature. Fluid uptake studies and mesenchymal stem cell affinity revealed the scaffold's capabilities as a suitable host for osteoprogenitor cells. In a 1 -cm rabbit diaphyseal segmental defect stabilized with an external fixator, tricalcium phosphate was compared to intact autograft, crushed autograft, and open defects. Torsional strengths and stiffnesses of tricalcium phosphatetreated tibia were greater than or equivalent to both intact and crushed autograft controls. Tricalcium phosphate pores exhibited complete bony infiltration histologically. Collectively, the tricalcium phosphate material properties, cell seeding capabilities, and in vivo biological responses give evidence of this implant's functionality as a potential alternative for autograft.
Trochanteric Osteotomy for Incarcerated Hip Dislocation Due to Interposed Posterior Wall Fragments
Authors: Anglen Jeffrey O , Hughes Michael
Published: December 2019

Abstract

A series of 12 patients was retrospectively reviewed to evaluate the use of sliding trochanteric osteotomy for reduction of hip dislocations that were irreducible due to interposed posterior wall fragments. Compared to similar patients who did not have irreducible dislocation or trochanteric osteotomy, the 12 patients had significantly longer operations with more blood loss. Patients with osteotomy tended toward a higher incidence of posttraumatic arthritis, but Harris hip scores at 2 years were identical to matched comparisons. No adverse effects of trochanteric osteotomy were identified.
