Published: February 2019

ABSTRAKLogika fuzzy memiliki aplikasi di berbagai bidang, namun memiliki arti khusus untuk penginderaan jarak jauh. Logika fuzzy memungkinkan keanggotaan parsial, bagian yang sangat penting dibidang penginderaan jarak jauh, karena keanggotaan parsial diterjemahkan secara dekat dengan masalah piksel campuran. Penelitian ini bertujuan untuk menerapkan algoritma klasifikasi logika fuzzy untuk memetakan habitat dasar Perairan dangkal pada Citra Satelit SPOT 7 dan Sentinel 2A, menguji tingkat akurasinya dan membandingkan algoritma klasifikasi logika fuzzy dengan maximum likelihood. Pengambilan data lapang berlokasi di gusung Karang Lebar dan Karang Congkak, Kepuluan Seribu pada tanggal 6 Desember sampai dengan 10 Desember 2017. Keseluruhan hasil uji akurasi menunjukan bahwa algoritma logika fuzzy masih memiliki tingkat akurasi yang baik dibandingkan dengan algoritma maximum likelihood. Perbedaan ukuran pixel (resolusi spasial) dari citra satelit juga mempengaruhi hasil akurasi, dimana citra satelit SPOT 7 memiliki tingkat akurasi yang lebih besar dibandingkan dengan Sentinel 2A.ABSTRACTFuzzy logic has applications in various fields, but has special meaning for remote sensing. Fuzzy logic allows partial membership, a very important property in the field of remote sensing, since partial membership is translated closely to the problem of mixed pixels. The aim of this research is to apply fuzzy logic classification algorithm to map benthic habitat in SPOT 7 and Sentinel 2A satellite imagery, test its accuracy level and compare fuzzy logic classification algorithm with maximum likelihood. Field data retrieval located in Karang Lebar and Karang Congkak, Kepulauan Seribu on 6 December until 10 December 2017. The overall accuracy test results show that fuzzy logic algorithm still has a good accuracy level compared to the maximum likelihood algorithm. Differences in pixel size (spatial resolution) of satellite imagery also affect accuracy results, where SPOT 7 satellite imagery has greater accuracy then Sentinel 2A.

Heavy metal pollution is one of serious problem for tropical mangrove ecosystem. Heavy metals can  decrease the quality of a waters. The decreasing in water quality can caused by pollutants such as heavy metals with high concentrations greatly affects the aquatic environment, especially living organisms. The aimed of study is to determine the accumulation level of heavy metals such as Al, Cu, Pb, As, Ni, Cr, Ti, Mn, dan Fe, in root, leaves and  stem of E. acoroides. The sampling was carried out in the northern and southern parts of Tunda Island, in March 2015. The method used for seagrass destruction is 6 mL 65% HNO3 and mL H2O2 30%, sediment destruction using Milestone Start D microwave labstation. and using ICP-OES (Inductive Coupled Plasma-Optical Emission Spectrometry) Thermo Scientific iCAP 700 Series. The result show that, the Al, was the dominant heavy metals observed both in sea water and sediment surrounding the observed sea grass areas. Similar result was also observed for seagrass.  The dominant sediment grain size absorbing heavy metals is silt-clay because it has more organic matter to control the binding of heavy metals. Heavy metal bioaccumulation is predominant in seagrass leaves and stems due to heavy metal entry into seagrass, substance storage tissue, and seagrass characteristics that are completely submerged in water. Seagrass meadow ecosystem in Tunda Island has been contaminated by several heavy metals.

Tässä artikkelissa tarkastellaan julkisen velkaantumisen vähentämisen pakkoa politiikkaideana, joka versoo talouden ja politiikan asiantuntijakeskusteluista, mutta saa tukea myös laajemmin jaetuista vastuullisen taloudenpidon järjestämistä koskevista käsityksistä. Erityisenä tutkimuskysymyksenä on, kuinka arkinen ymmärrys kestävän taloudenpidon ehdoista tukee poliittista argumenttia velan vähentämisen välttämättömyydestä. Analyysi perustuu vuodelta 2015 kerättyyn verkkokeskusteluaineistoon, joka sisältää 1060 kommenttia velkaantumiseen ja valtiontalouden tasapainoon liittyvistä uutiskeskusteluista.

Analyysissa eritellään kolme diskursiivista muodostelmaa, velkapelon rationaliteettia, jotka yhdessä tukevat julkisen velkaantumisen vähentämisen pakon politiikkaidean ymmärrettävyyttä ja hyväksyttävyyttä: talous neutraaleina tosiasioina, talous moraalisena vastuunkantamisena sekä talous politiikan reunaehtoina. Lisäksi artikkelissa tarkastellaan näitä rationaliteetteja haastamaan pyrkiviä vastapuheita. Artikkeli osoittaa, että velkaa koskevan keskustelun taustalta voidaan tunnistaa syväänjuurtuneita periaatteita, jotka ilmentävät käsityksiämme talouden, politiikan ja moraalin suhteista.
Ситуация на рынке продовольствия: новые сигналы и старые проблемы
Authors: Белова Т. Н.
Published: February 2019

Современная ситуация на агропродовольственном рынке характеризуется, с одной стороны, дифференциацией его сегментов по степени насыщения, а с другой–снижением спроса. Падение реальных доходов населения обусловило снижение потребительского спроса и увеличение доли расходов на питание в домашних хозяйствах, о чем свидетельствует анализ региональной статистики. В последние годы растет расслоение как по производству, так и по потреблению продовольствия на душу населения. Опережающий рост цен на продовольствие ставит под сомнение верность выбора мер и инструментов политики протекционизма. Правильный протекционизм, по мнению автора, не может осуществляться за счет снижения уровня жизни населения, а должен сочетать рыночные механизмы с точечной временной поддержкой тех отраслей экономики, для которых характерны растущая доходность и высокая отдача на инвестиции. Автор считает необходимым использование инструментов «зеленой корзины» (в частности программу продовольственных карточек), отмену эмбарго на импорт продовольствия и дифференциацию экспортных и импортных таможенных пошлин в зависимости от степени насыщения и сформированности внутренних отраслевых рынков.

В 2014 г. Федеральная антимонопольная служба РФ предложила ввести международный принцип исчерпания прав на товарные знаки в России (легализовать параллельный импорт брендированной продукции) поэтапно для отдельных групп товаров. При этом критерии выбора товарных групп для первоочередного изменения режима импорта не были сформулированы. Авторы статьи попытались с учетом существующего опыта оценки эффектов параллельного импорта сформулировать критерии отбора товарных категорий для легализации параллельного импорта в первую очередь. Товарные группы выделялись на основе анализа состава «защищенных» товарных знаков (внесенных в ТРОИС), внешнеторговых потоков брендированной продукции и объемов инвестиций правообладателей в России.

Abstrak: Fajar adalah fenomena alami yang terjadi disebabkan rotasi Bumi pada porosnya. Permasalahan awal waktu fajar senantiasa menjadi kajian baik di kalangan fukaha maupun ilmuwan Muslim. Di Indonesia, sejak lama berlaku ketetapan dip-20 derajat di bawah ufuk dalam penentuan waktu Subuh. Ketentuan ini berasal dari pendapat Syaikh Muhammad Thahir Jalaluddin (w. 1376/1956) dalam karyanya Nukhbah al-Taqrîrât fi Hisâb al-Auqât. Makalah ini akan menelusuri pemikiran Syaikh Muhammad Thahir Jalaluddin tentang hal ini melalui karyanya tersebut dalam merumuskan konsepsi 20 derajat ini. Melalui analisis dan penelusuran sejumlah literatur, ditemukan bahwa dip -20 derajat ini ternyata dihasilkan hanya berdasarkan nukilan dari karya dan atau pemikiran tokoh-tokoh sebelumnya baik tokoh Nusantara maupun tokoh yang bermukim di Haramain, khususnya melalui kitab al-Mathla‘ al-Sa‘îd karya Husain Zaid Mesir.

Abstract: Shaykh Muhammad Thahir Jalaluddin’s Contribution in Islamic Astronomy. This article studies on the early dawn time and its influence on the determination dawn in Indonesia. Dawn is a natural phenomenon that can be seen while the earth rotates on its axis. The issue of the beginning of dawn has become a heated debate both within the Indonesian Muslim scholars (fuqaha) and scientists alike. In Indonesia, to determine dawn prayer’s time has been set up dip -20 degree below the horizon. This determination was adopted from Muhammad Thahir Jalaluddin’s idea in his work Nukhbah al-Taqrîrât fi Hisâb al-Auqât. This paper is trying to explore Muhammad Thahir Jalaluddin’s thought concerning the issue through his work which formulated this conception of 20 degree. In this article, the author found that after a thorough and critical analysis of some important literature and references, it is concluded that this conception was strictly quoted from other works and other previous Muslim scholars idea who lived in Haramain, especially in the book al-Mathla‘ al-Sa‘îd which was written out by Husain Zaid Mishr.

MODIFIKASI MODEL PEMBELAJARAN CONTEXTUAL TEACHING AND LEARNING (CTL) DENGAN STRATEGI PEMBELAJARAN TUGAS DAN PAKSA
Authors: Simatupang Puput Najariah , Sari Putri Indah
Published: February 2019

The lack of creativity created by teachers and students in the classroom and the weak process of learning activities in Indonesia is a problem that must be evaluated and solutions are sought, especially by teachers. The teacher is the first spearhead to determine whether the learning and learning process can work well. The learning model used in this writing is Contextual Teaching and Learning which is modified by task and forced strategies. CTL is a learning concept that helps teachers associate material taught with students' real world situations and encourages students to make connections between their knowledge and their application in their lives as family members and society. The contextual learning model is not exclusive but can be combined with other learning models, for example: discovery, process skills, experiments, demonstrations, discussions, and others. The purpose of this writing is to help teachers improve their creativity, activeness and motivation in the classroom. However, to make students become more active and creative in class, the right strategy is required, which is task and forced. This strategy focuses on giving assignments that are accompanied by a little coercion right in the hope that students can complete their tasks properly at the appointed time. To implement Contextual Teaching and Learning with Task and Forced Strategies teachers should make a scenario and plan better and more mature. The teacher should master and understand in advance the rules, the nature and theory of this learning model, and the teacher must always provide motivation to students to be more active and better at learning.

Latent class cluster analysis
Authors: Ünlü Ali
Published: February 2019

This paper describes the technique of exploratory latent class cluster analysis. The classical analysis is a model-based statistical approach for identifying unobserved subgroups from observed categorical data and for classifying cases into the identified subgroups based on membership probabilities estimated directly from the statistical model. In the first part on mathematical modeling of the paper, we introduce the data and the sampling distribution for the data as required in the analysis of latent classes, the fundamental model assumptions are reviewed, and the general unrestricted latent class model is presented. Classification of cases into the clusters using modal assignment is discussed. In the second part on inferential statistics of the paper, we briefly review the classical maximum likelihood methodology related to parameter estimation and model testing, and the information criteria AIC and SIC for model selection. In the third part on case study of the paper, the General Social Survey data are analyzed using the software Latent GOLD. We present the Latent GOLD profile plot and tri plot options for the graphical representation of the results. The Latent GOLD classification output illustrating the assignment of respondents to the latent survey respondent types is also shown.
Pre-sleep Cognitive Influence of Night-time Social Media Use and Social Comparison Behaviour in Young Women
Authors: McNee Shannon , Woods Heather
Published: February 2019

Night-time social media use in young people has received significant attention from the international media, governments, and policymakers due to its published associations with increased depression, anxiety, and sleep problems. However - as not all young people engage with social media in the same way - there are calls for a shift of research focus away from suggested negative impacts of social media use and towards nuanced understanding of social media engagement style. As a result, individual differences in social media engagement must be appreciated when considering the relationship between social media use and wellbeing. The current study presents pilot data which highlights an association between social comparison orientation, night-time social media use, mental wellbeing, and sleep in female users of Facebook and Instagram (N = 60). Social comparison orientation, rumination tendency, sleep health, and night-time social media use were examined using online questionnaire measures. Social comparison orientation was found to be positively associated with night-time social media use and rumination tendency. In addition, rumination was highlighted as a significant mediator of the relationship between social comparison behaviour and poor sleep – suggesting that the behaviours we engage in online may influence sleep through a cognitive pathway. Our findings contribute to a growing body of research which demonstrates how the nature of social media interactions can impact wellbeing with implications for the design of integrated social media literacy and sleep interventions.
Merits and Limits: Applying open data to monitor open access publications in bibliometric databases
Authors: Akbaritabar Aliakbar , Stahlschmidt Stephan
Published: February 2019

Identifying and monitoring Open Access (OA) publications might seem a trivial task while practical efforts prove otherwise. Contradictory information arise often depending on metadata employed. We strive to assign OA status to publications in Web of Science (WOS) and Scopus while complementing it with different sourcesof OA information to resolve contradicting cases. We linked publications from WOS and Scopus via DOIs and ISSNs to Unpaywall, Crossref, DOAJ and ROAD. Only about 70% of articles and reviews from WOS and Scopus could be matched via a DOI to Unpaywall. Matching with Crossref brought 53 distinct licences, which define in many cases the legally binding access status of publications. But only 53% of publications hold only a single licence on Crossref, while more than 42% have no licence information submitted to Crossref. Contrasting OA information from Crossref licences with Unpaywall we found contradictory cases overall amounting to more than 13%, which might be partially explained by (ex-)including green OA. A further manual check found about 17% of OA publications that are not accessible and about 15% non-OA publications that are accessible through publishers’ websites. These preliminary results suggest that identification of OA state of publications denotes a difficult and currently unfulfilled task.

Tele-monitoring Technology as a Tool for Monitoring and Management of Patients with Congestive Heart Failure
Authors: Vlahu-Gjorgievska Elena , Nagapuri Swetha , Win Khin Than
Published: February 2019

Telehealth interventions are designed to facilitate the remote exchange of information and data between patients and health care providers, improving the quality and safety of the patients and increasing efficiency and cost-effectiveness of health care providers. The development of telecommunications and virtual technology allowed a number of telehealth systems to be applied in different health care areas. These technologies can provide an alternative monitoring and solutions for decreasing the hospital readmission rates for patients with congestive heart failure (CHF). In this paper, a systematic literature review regarding tele-monitoring and its use in the management of patients with CHF is conducted. The result indicated that a standardized tele-monitoring design would reduce a length of hospitalization and re-hospitalization rate. The other factors that moderate the effectiveness of the tele-monitoring intervention include quality of life, mortality rate, and disease-specific knowledge (health literacy). All these factors align with the consumer-centred principle of The Australian Safety and Quality Framework for Health Care.
A Design Construct of Developing Approaches to Measure Mental Health Conditions
Authors: Islam Md Rafiqul , Miah Shah Jahan , Kamal Abu Raihan M. , Burmeister Oliver
Published: February 2019

Mental health is an important determinant of communities’ well-being, influenced not only by individual attributes, but also by social and organisational environments in which people work and live. Despite studies examining mental health status among specific populations, few attempts are evident that focus on solution designs for detecting and measuring impact of mental health conditions. In this study, we develop a construct utilising design science research principles for outlining common vocabulary around the problem, and solution design relevant to a mental health management system. For the case of IT professionals, the developed construct is informed through a social-media based dataset containing more than 65,000 cells and 100 attributes potentially identifying influencing factors. Machine learning techniques are applied to the dataset to discover new findings for this specific group. It is anticipated that the analysis reported in this study would contribute in developing other electronic health management systems both for communities and healthcare professionals
The Experiences of Three Different User Groups Using Personally Controlled Health Record for Multidisciplinary Care Team
Authors: Ghandour Nadia , Ghandour Ahmad
Published: February 2019

Personally Controlled Health Records (PCHR) are patient-centric tools which allow individuals to own, manage, access and share their health information online from anywhere, at any time. Patient-centric tools have received considerable interest and investment in recent years worldwide. These tools are thought to have the potential to increase individuals’ self-management and involvement in their own health, as well as improve healthcare efficiency and delivery. The aim of this study is to report and analyse the experiences of three different user groups using PCHR for Multidisciplinary Care Team (MDCT) including the advantages, disadvantages, barriers and obstacles, and the current state of PCHR. In order to achieve the aim of this study, sixteen interviews with key informants from three different user groups were conducted in Dunedin, New Zealand. Interviews were transcribed and analysed with thematic analysis. The key findings of this research showed that those who can benefit the most from PCHRs are the least able to use it. It suits those who have basic knowledge about computers and the internet and those who can afford to use them. PCHR is also best suited for individuals who are motivated about their health despite their health condition. However, more research is needed in the future with a larger sample, an easier to use PCHR, different population other than community health workers, patients with different chronic illnesses, and healthy patients. This research can be used as a basis and tested in future research on PCHR adoption.

Relationship between the variation in transformation temperatures, resistivity and dislocation density during thermal cycling of Ni50Ti50 shape memory alloy
Authors: Sibirev Alexey , Resnina Natalia , Belyaev Sergey
Published: February 2019

The aim of the present work is to find the relationship between a decrease in transformation temperature and an increase in dislocation density during thermal cycling of NiTi alloy. The resistivity is used as a measure of the dislocation density variation and it allows one to find a linear dependence of the increment in the transformation temperatures on the dislocation density variation starting with the fifth thermal cycle. It is found that the thermal cycling of NiTi alloy within a temperature range of 473 to 273 K is accompanied by less dislocation density variation than in a range of 413 to 273 K. The dependence of transformation temperatures on increase in dislocation density in the first five cycles is not linear, hence it is concluded that the dislocation density variation is not the unique reason for a decrease in transformation temperature during the thermal cycling of equiatomic NiTi alloy.

The Safety of Patients in Surgery. Part 1: Conceptual Basis of the Problem
Authors: Karsanov Alan , Polunina Nataliya , Gogichaev Tamerlan
Published: February 2019

The article is devoted to the search for the fundamental bases for the effective solution of the problem of the safety of surgical patients (SSP), which becomes a key direction in improving the surgical services of each medical organization. The definition of SSP is proposed as a complex concept combining progressive educational, clinical and managerial technologies aimed at preventing the negative consequences of surgical treatment, based on their internal connections and general development prospects. This allowed to justify the implementation of an integrated approach to its solution in practice.
Obligatory components of the organizational structure of such an approach are: informational-legal, educational-motivational, surgical (perioperative), control-administrative and organizational. The necessary technological processes for this are considered by the authors: standardization, creation of a single legal and educational platform for all subjects of medical law, personnel management, the process principle of technology implementation, risk management, improvement of information support. The unity of the components and elements of the SSP program is harmonized with the principle of mutual potentiation of their specific requirements, which are consistent with the main goal – the restoration of the patient’s health.

Introducción: La bacteriemia por Staphylococcus aureus (SA) constituye una de las más graves infecciones de la edad pediátrica.

Objetivos: Evaluar las características epidemiológicas, clínicas y laboratoriales de niños con bacteriemias por SA adquiridas en la comunidad (SAAC), identificar factores de riesgos asociados a mortalidad.

Materiales y métodos: Estudio retrospectivo en el que se incluyeron pacientes (pts) de ≤16 años, hospitalizados entre 2010-2018, con dx de bacteriemias por SAAC. Los datos clínicos y laboratoriales fueron introducidos en una base de datos de Excel y formateados para  análisis.

Resultados: Se identificaron 117 pts con una edad media de 56+53 meses, de los cuales 81 fueron≤ 5 años. La bacteriemia se asoció principalmente a neumonía (47% de los casos), presentando choque el 38% e ingreso a UCI el 40% de los pts. En el 27% (32/117) la bacteriemia fue por SAMR. La edad <5 años (p=0.0001), presencia de choque (p=0001), hospitalización en UCI (p=0.002, OR 3.58, IC95% 1.5-8.3) y la mortalidad (p=0.03, OR 2.65, IC95% 1.05-6.7) se asociaron a infección por SAMR. La mortalidad de esta serie fue del 21 % (25/117). La presencia de comorbilidad (p=0.006, OR3.66, IC95% 1.4-92), choque (p=0.0001, OR 87.6, IC 95% 11.5-687.7), focos múltiples infecciosos (p=0.007,OR3.46, IC 95% 1.3-8.9), aislamiento de  SAMR (p=0.03, OR 2.65,IC 95% 1.1-6.7), y trombocitopenia <100 000/mm3 (p= 0.0001, OR 25.3, IC 95% 5-128) se asociaron a mortalidad.

Conclusiones: El presente estudio muestra la severidad de la bacteriemia por SA. La resistencia a meticilina, la comorbilidad, la presencia de focos múltiples y choque se identificaron como factores asociados a mortalidad.

Objetivo: Determinar la prevalencia de traumatismos dentales en los pacientes que acuden a una clínica de Especialidad en Odontopediatría.

Materiales y Métodos: Se realizó un estudio transversal retrolectivo, se incluyeron 309 expedientes clínicos de pacientes de 2 a 12 años de edad que acudieron para su atención a la clínica de la Especialidad de Odontopediatría de una universidad pública en Toluca, México. La variable dependiente fue la prevalencia de traumatismo dental. Las variables independientes incluidas en el estudio fueron: edad del paciente y sexo. El análisis estadístico se realizó utilizando pruebas no paramétricas en Stata 11.

Resultados: El promedio de edad fue de 5.71±2.43 años y el 50.8% fueron hombres. La prevalencia de traumatismo dental previo al estudio fue de 12.0% (IC 95% = 8.3 – 15.6). En el análisis bivariado, a pesar de que los varones presentaron una prevalencia de traumatismo dental de 14.0% y entre las mujeres fue de 9.9%, estas diferencias no fueron estadísticamente significativas (p=0.262). Se observó que los niños con traumatismo dental fueron más pequeños (promedio de edad = 4.74±1.86) que los que no presentaron traumatismo dental (promedio de edad = 5.84±2.47) (p=0.0166). Al realizar la prueba de tendencia no paramétrica se notó que la disminución de la prevalencia de traumatismo dental fue significativa (p=0.026).

Conclusiones: La prevalencia de traumatismo dental en esta muestra de niños fue de 12%. No se observó diferencia por sexo. Los más pequeños presentaron más traumatismo dental que los más grandes.

Published: February 2019

Introducción: La hiperdoncia, es una anomalía de número en la que se forman dientes o estructuras parecidas a dientes en exceso con respecto a la cantidad normal, teniendo como resultado órganos dentales llamados supernumerarios.

Presentación del caso: Paciente masculino de 7 años 11 meses de edad con dentición mixta y retraso en la erupción de los incisivos centrales y laterales superiores. En la radiografía panorámica se observa una zona radiopaca entre el incisivo central superior permanente (OD 21) y el incisivo lateral superior permanente (OD 22) diagnosticando un diente supernumerario. Con ayuda de una radiografía oclusal y una periapical de la zona se valoró y se determinó su extracción bajo anestesia local. Se realizó la cirugía sin complicaciones y se derivó al paciente a la clínica de ortodoncia.

Conclusiones: En el presente reporte se pudo observar que llevando un buen control del caso y con la ayuda de estudios radiográficos se puede lograr un avance significativo sin dañar la integridad bucal del paciente en un futuro. Significancia clínica: El diagnóstico precoz puede mejorar con ayuda de los diversos tipos de radiografías disponibles en odontología, así se evitan complicaciones al paciente infantil.
