Para ello, se llevaron a cabo las fases: preparación del terreno y diseño de figuras geométricas, recolección de datos en la huerta escolar, creación de guías de trabajo y análisis de su efecto en el aprendizaje significativo de los estudiantes y los docentes.
The Value in Community Gardens: A Return on Investment Analysis
Authors: Cochran Susie , Minaker Leia
Published: July 2020

Food production in cities is increasingly regarded as one of the building blocks for sustainable urban living, particularly as the agricultural industry faces mounting ecological and economic constraints, and populations continue to concentrate in urban centers. While substantial research exists on the qualitative outcomes of urban agriculture (UA), few studies present these outcomes in monetary terms that align with municipal decision makers economic priorities. In response to this gap, this paper reviews the literature on potential outcomes of one form of UA—community gardens—and identifies where gaps exist which prevent the translation of garden outputs into an economic quantity. The paper then describes a pilot return on investment assessment of a community garden in Ontario, Canada. Substantial data constraints were encountered, however the limited available data indicate that community gardens may represent an ROI-positive government investment. Further local-level research quantifying garden impacts would enable a more robust case for community gardens in cities.
Starving to be a student: The experiences of food insecurity among undergraduate students in Nova Scotia, Canada
Authors: Bessey Meredith , Frank Lesley , Williams Patricia L.
Published: July 2020

Household food insecurity (HFI) exists when access to food is inadequate or insecure due to financial constraints, and is an issue of increasing concern among postsecondary students who face barriers to food access due to precarious finances. The goal of the current study was to explore the experience of HFI among university students in Nova Scotia (NS), including barriers and facilitators, and potential policy solutions to the issue from the perspective of students. Twelve semi-structured, in-depth interviews were conducted with students experiencing HFI from across NS. Phenomenological analysis was undertaken, using Radimer’s model of HFI as a theoretical framework. Key aspects of the experience of food insecurity in this sample included all four dimensions of Radimer’s model of HFI: quantitative, qualitative, psychological, and social. The main contributing factor to student’s difficulties accessing food was inadequate and precarious finances. Students highlighted various coping mechanisms, such as utilizing food banks, budgeting their money, and buying food in bulk. This study is an important next step to a better understanding of the experience of student HFI in NS, building on previous quantitative research. Findings suggest that while the experience of HFI has many similarities with the experience in other populations, students experience tensions between independence and reliance on their family and have unique struggles related to government financial supports. The findings point to necessary policy changes related to student funding programs, and suggest that relying on campus food banks to solve the issue of HFI among students is inadequate.
Obscuring the Veil
Authors: Winter Ellyse
Published: July 2020

Working with Karl Marx’s concept of commodity fetishism, the purpose of this paper is to argue that food advertisements and packaging work to further obfuscate the social, economic, and environmental relations behind the animal products and by-products consumed in Canada and the United States. The paper discusses the socio-ecological implications of the animal-industrial complex and employs a critical discourse analysis to examine how advertisements for animal products and by-products function as sites of public pedagogy to obscure these adverse effects. Finally, this paper outlines a vision of critical food pedagogies that both ‘removes the veil’ (Hudson & Hudson, 2003) and addresses the underlying generative framework that drives our relationship with an industrial food system
“They hold on tight to the healthy eating, we hold on tight to our food safety, and how do we bridge that?”: determinants of successful collaboration between food safety and food security practitioners in British Columbia, Canada

Published: July 2020

Food safety and food security are two important public health sectors within Canada, which aim to address foodborne disease and food insecurity, respectively.  While these sectors are often siloed within public health organizations, the actions of the two sectors often interact and conflict at the program level despite their common goal of improving population health.  The objective of the present study was to identify determinants that influenced the success of collaboration between practitioners of the two sectors in British Columbia, to inform Canadian food policy.  We inductively analyzed 14 interviews with practitioners working in the two sectors who had experience with successful collaboration. Data were interpreted in consultation with an inter-professional collaboration framework.  Participants identified determinants at the systemic level, including the cultural, professional, educational, legislative, and political systems, which were often considered barriers to collaboration.  Participants also identified determinants at the organizational level that influenced the success of collaboration between the sectors, including: the organization’s structure and philosophy, leadership, resources, and communication mechanisms.  Finally, participants identified interactional determinants as ways to overcome existing barriers, including: willingness to collaborate, trust, communication, mutual respect, and taking a solutions-oriented approach.  Practitioners working in food safety and food security can apply the interactional determinants identified in this study to mitigate existing barriers to collaboration and support more synergistic food policies.

Authors: Alegre L.M. , Sánchez-Ramírez C.
Published: July 2020

El objetivo de esta investigación fue analizar modificaciones agudas que se producen en la morfología del pie y distribución de presiones plantares luego de la aplicación de un protocolo de carrera a pie descalzo. 42 sujetos de ambos sexos participaron de este estudio, quienes fueron divididos en Grupo Calzado (GC) (n=20) y Grupo Descalzo (GD) (n=22). Se evaluó antropometría del pie, índice del arco (AI) y presiones plantares antes y después de la intervención, que consistió en correr a 3,05 m·s-1 durante 20 min. El pie no dominante del GD disminuyó la altura de su arco plantar (AI pre=0,20, AI post=0,22; p=0,01; ES=0,4), asimismo, la carrera descalza produjo en el pie no dominante menores aumentos en los valores de presión plantar y menores disminuciones en la superficie de apoyo plantar que el correr con calzado.

Authors: Antúnez A. , García-Ceberino J.M. , Feu S. , S.J. Ibáñez
Published: July 2020

El propósito del estudio fue validar dos programas de intervención, correspondientes a dos unidades didácticas realizadas cada una en base a dos metodologías diferentes: Direct Instruction (ID) y Tactical Games Approach (TGA), para la enseñanza del fútbol escolar. Se diseñaron dos programas de intervención semejantes con el mismo número de tareas, sesiones, fases de juego, contenidos y objetivos. En el proceso de validación participaron 13 jueces expertos. La validez de contenido se calculó mediante el coeficiente de V de Aiken y sus intervalos de confianza. Para la consistencia interna se empleó el coeficiente de ? de Cronbach. Ninguna de las tareas que componen los programas de intervención fue eliminada al superar el valor crítico exacto (V ? .69). La consistencia interna de las tareas fue excelente (? = .97). Por tanto, ambos programas de intervención son válidos y fiables para la enseñanza del fútbol escolar, así como para comparar los efectos de ambas metodologías.

Published: July 2020

En los deportistas la masa libre de grasa (MLG) es una característica física que se busca incrementar para aumentar el rendimiento deportivo. El objetivo de este estudio fue determinar si la reducción de la MLG, expresada como índice AKS, se asocia a alteraciones fisiológicas después de un periodo de entrenamiento en nadadores de 8 a 15 años de edad. Se estudiaron 42 nadadores, después de 15 semanas de entrenamiento se formaron 2 grupos, los que disminuyeron (A) y aumentaron (B) MLG. Se encontró que el grupo A redujo el peso y la masa muscular mientras que en el grupo B aumentó. En el grupo A se observó una disminución en los linfocitos, un aumento en la urea sérica, una disminución en el VO2 y en la recuperación a un minuto. La reducción de la MLG se asoció con alteraciones fisiológicas que reducen el rendimiento deportivo.
VARIABILIDAD DE LA FRECUENCIA CARDIACA Y EJERCICIO. ¿FUNDAMENTACIÓN FISIOLÓGICA?
Authors: Calderón F.J. , Cupeiro R. , Peinado A.B. , Lorenzo-Capella I.
Published: July 2020

Este trabajo pretende dos objetivos: 1º) dar una visión pedagógica de la complejidad relativa al tratamiento matemático de la variabilidad de la frecuencia cardiaca y 2º) analizar si el tratamiento matemático de la señal RR (distancia entre dos ondas R del electrocardiograma) tiene una base fisiológica. Se revisan los mecanismos fisiológicos que explican uno de los fenómenos de base para el análisis de la variabilidad: la arritmia sinusal respiratoria. Se analizan las bases matemáticas, así como los métodos matemáticos de valoración, de la variabilidad. Finalmente, se realiza una revisión del significado fisiológico de las bandas de frecuencia obtenidas mediante las diversas metodologías del tratamiento de la señal RR. No está claro si los métodos matemáticos de tratamiento de la señal RR pueden ser una herramienta de valoración de la función vegetativa. Por ello, debemos tener precaución al interpretar esta variable, sobre todo en el contexto del ejercicio físico y entrenamiento.

Published: July 2020

El objetivo de este estudio fue describir una metodología de seguimiento en una atleta que combina el Ultra Trail Running (UTR) y el Ironman durante 16 semanas, mediante variabilidad de la frecuencia cardiaca (VFC).
La carga de entrenamiento (CE) diaria se programó y se cuantificó el sumatorio semanal. Se registraron los intervalos RR (ms) en reposo cada mañana durante 5 minutos y a partir de ellos se midió la RMSSD (raíz cuadrada de la media de las diferencias de la suma de los cuadrados entre intervalos RR adyacentes) como medida de la actividad parasimpática y el índice de estrés (SS) como actividad simpática.
Los registros diarios de VFC matutinos parecen ser una forma útil para monitorizar el estado de equilibrio simpático-parasimpático en deportistas antes de abordar las sesiones de entrenamiento. Esta monitorización serviría para detectar precozmente estados de fatiga y para poder monitorizar la planificación de las cargas.

Published: July 2020

Asisten rumah tangga merupakan suatu pekerjaan yang sering di pandang sebelah mata, terutama ART perempuan yang memang rentan sekali mengalami tindak kekerasan, intimidasi, diskriminasi dan juga penelantaran hak-haknya sebagai pekerja. Dengan demikian perempuan ART membutuhkan perlindungan baik berupa Undang-undang maupun lembaga bantuan hukum yang berupaya melakukan perlindungan terhadap hak- hak perempuan ART. Hal tersebut menjadi latar belakang mengapa penelitian ini dilakukan, yaitu untuk mengetahui bagaimana regulasi terkait dengan perempuan asisten rumah tangga? Bagaimana advokasi hak-hak perempuan asisten rumah tangga oleh LBH APIK Jakarta?Penelitian ini menggunakan metode kualitatif yang bersifat deskriptif yaitu menggambarkan situasi tertentu berdasarkan data yang diperoleh di lapangan secara terperinci terkait dengan hak-hak perempuan asisten rumah tangga. Teknik pengumpulan data yang dilakukan penulis adalah penelitian lapangan dengan melakukan wawancara kepada tiga orang pengacara dan satu orang koordinator internal, dokumentasi di LBH APIK Jakarta, serta penelitian kepustakaan yakni memperoleh data ilmiah dan akurat yang bersumber pada buku-buku, artikel dan juga jurnal yang berkaitan dengan pokok pembahasan. Dalam pemilihan informan penulis menggunakan purposive sampling.Hasil penelitian ini menunjukan bahwa terdapat beberapa regulasi yang dapat digunakan dalam melindungi perempuan Asisten Rumah Tangga dari tindak kekerasan, diskriminasi, intimidasi dan juga penelantaran hak-haknya. Selama payung hukum bagi ART masih belum disahkan sebagai Undang-Undang maka regulasi tersebut dapat digunakan sebagai acuan ataupun penguat didalam melakukan advokasi, slah satunya Undang-Undang KDRT yang digunakan LBH APIK Jakarta sebagai acuan dalam penanganan kasus. Adapun hasil penilitian ini juga menunjukan bahwa advokasi yang dilakukan LBH APIK Jakarta terkait hak-hak perempuan Asisten Rumah Tangga yang memiliki dua model dalam melakukan perlindungan terhadap hak-hak perempuan ART yaitu dengan cara penanganan kasus dan juga berupaya untuk memberikan perlindungan khusus terhadap ART dalam bentuk Undang-undang PRT yang masih di prioritaskan dan diadvokasikan sampai saat ini.

Authors: Yasir Yunan Zulfahmi
Published: July 2020

Abstract. Domestic violence is one social problem that is often found in the community. However, to uncover the case is very difficult, such as violence perpetrated by parents against children. The purpose of this study is to find out the coping strategies carried out by children who experience violence committed by their own parents. A person’s internalization of a violence experience and social resources will direct one’s efforts in overcoming problems and ultimately determine a person’s psychological state. The results of this study indicate each subject of the study posses a different family background, but there are similarities from both of which are equally derived from a harmonious family. On the other hand, the perpetrators of violence in this study generally had the same experience of violence in their childhood. The reaction of the two subjects to the acts of violence and trauma they experienced are in common, namely being self-blame and taking the positive aspects of each incident. Certain coping strategies they practice can overcome the stress conditions. Abstrak. Kekerasan dalam rumah tangga menjadi salah satu yang sering dijumpai di tengah-tengah masyarakat. Akan tetapi untuk mengungkap kasus ini sulit sekali, seperti kekerasan yang dilakukan orang tua terhadap anak. Tujuan dari penelitian ini adalah mengetahui strategi coping yang dilakukan oleh anak yang mengalami kekerasan yang dilakukan oleh orang tuanya sendiri. Penghayatan seseorang terhadap pengalaman kekerasan yang diterima serta sumber-sumber yang dimilikinya akan mengarahkan usaha seseorang dalam mengatasi permasalahan dan pada akhirnya menentukan keadaan psikologis seseorang. Hasil yang diperoleh dari penelitian ini adalah, masing-masing subyek dalam penelitian ini memiliki latar belakang keluarga yang berbeda, namun terdapat persamaan dari keduanya yaitu sama-sama berasal dari keluarga yang harmonis. Sedangkan pelaku kekerasan dalam penelitian ini pada umumnya memiliki pengalaman kekerasan yang sama yakni pada masa kecilnya mengalami tindak kekerasan. Reaksi kedua subyek terhadap tindak kekerasan dan trauma yang dialaminya memiliki kesamaan, yakni bersikap menyalahkan diri sendiri dan mengambil segi positif dari setiap kejadian. Strategi coping tertentu yang mereka lakukan cukup dapat mengatasi kondisi stress yang dialaminya.
FILOSOFI SISTEM KEKERABATAN MATRILINEAL SEBAGAI PERLINDUNGAN SOSIAL KELUARGA PADA MASYARAKAT MINANGKABAU
Authors: Sukmawati Ellies
Published: July 2020

Abstract. Minangkabau is one of the tribes in Indonesia using matrilineal as a kinship system in which the formation of lineage is arranged according to the female line. The Minangkabau kinship system uses a “Gadang” house as its symbol. The inheritance inherited by the family in the form of a “Gadang” house and assets in agriculture and fisheries to be managed and utilized together by one family (a “paruik”). Every female lineage in the family has the right to live in a “Gadang” house and their children are raised on funding from inheritance. The shared responsibility (communal) in the Minangkabau matrilineal system is seen in the supervision model applied in it, where the task of supervising and educating children in the matrilineal family is the mother and her mother’s brothers (mamak), as well as adults others inside the “Gadang” house. This study combines social protection systems with the philosophy of the Minangkabau matrilineal kinship system which can play a role in protecting the community from social problems that can disrupt the stability of the welfare of a family. But over time this matrilineal system has faded, but the symbols of the system of Gadang house can still be seen in the Minangkabau community, including those who have migrated and settled outside West Sumatra.   Abstrak. Minangkabau merupakan salah satu suku di Indonesia mempergunakan matrilineal sebagai sistem kekerabatannya di mana pembentukan garis keturunan diatur menurut garis perempuan. Sistem kekerabatan Minangkabau mempergunakan rumah gadang sebagai simbolnya. Harta pusaka yang diwariskan oleh keluarga berupa rumah gadang dan aset di bidang pertanian maupun perikanan untuk dikelola dan dimanfaatkan secara bersama oleh satu keluarga (sabuah paruik). Setiap keturunan perempuan dalam keluarga berhak untuk menghuni rumah gadang dan anak-anak mereka dibesarkan dengan pembiayaan dari harta pusaka. Tanggung jawab bersama (communal) di dalam sistem matrilineal Minangkabau terlihat pada model pengawasan yang diterapkan di dalamnya, di mana yang bertugas mengawasi dan mendidik anak-anak dalam keluarga matrilineal adalah ibu dan saudara laki-laki ibunya (mamak), serta orang-orang dewasa lainnya di dalam rumah gadang. Penelitian ini menggabungkan sistem perlindungan sosial dengan filofosi sistem kekerabatan matrilineal Minangkabau yang dapat berperan untuk memproteksi masyarakat dari permasalahan sosial yang dapat mengganggu stabilitas kesejahteraan suatu keluarga. Namun seiring waktu sistem matrilineal ini telah semakin memudar, namun simbol-simbol sistem rumah gadang masih dapat terlihat pada masyarakat Minangkabau, termasuk dengan mereka yang telah merantau dan menetap di luar Sumatera Barat.

Abstract. The purpose of this research is to describe the form of social capital in the development of urban farming in the hydroponic village of Pangadegan, South Jakarta, DKI Jakarta. Data collection is done through interviews, documentation and observation. Data is processed and analyzed through a three-stage data encoding technique: open encryption, axial encryption and selective encryption. Arguments are formulated through analysis using Putnam’s social capital theory which focuses on networks, norms, and beliefs. The result is that social capital in developing urban farming in Pengadegan Village can be described in 3 ways, namely ties of trust, social institutions, and social networks. Relating to the bond of trust can be seen from the community including Gapoktan and the Village Government have the same passion and commitment to greening the environment and building community cohesiveness. Besides that, from social institutions, it can be seen that Gapoktan has its own written rules, both Gapoktan Gang B and Gang C. The written rules contain the duties and functions of each member. Social networks can be seen by showing that there are two Gapoktan who have different principles, Gapoktan in Gang C chooses to independently develop Hidroponik village, Gapoktan in Gang B prefers to develop the widest network both for the government and the private sector.  Abstrak. Tujuan dari penelitian ini adalah untuk menggambarkan bentuk modal sosial dalam pengembangan urban farming di kampung hidroponik Kelurahan Pangadegan Kota Jakarta Selatan DKI Jakarta. Pengumpulan data dilakukan melalui teknik wawancara, dokumentasi dan observasi. Data diolah dan dianalisis melalui teknik tiga tahap penyandian data: penyandian terbuka, penyandian aksial dan penyandian selektif. Argumen dirumuskan melalui analisis dengan menggunakan teori modal sosial dari Putnam yang memfokuskan pada jaringan, norma, dan kepercayaan. Dari hasil analisis peneliti ditemukan bahwa modal sosial dalam pengembangan urban farming di Kelurahan Pengadegan dapat digambarkan dalam 3 hal yaitu ikatan kepercayaan, pranata sosial, dan jaringan sosial. Berkaitan dengan ikatan kepercayaan dapat dilihat dari masyarakat termasuk Gapoktan dan Pemerintah Kelurahan memiliki semangat dan komitmen yang sama yakni untuk menghijaukan lingkungan dan membangun kohesifitas masyarakat. Selain itu dari pranata sosial dapat dilihat Gapoktan memiliki aturan tertulis masing-masing, baik Gapoktan Gang B maupun Gang C. Aturan tertulis tersebut berisi tugas dan fungsi masing-masing anggota. Jaringan sosial dapat dilihat dengan menunjukkan bahwa terdapat dua Gapoktan yang memiliki prinsip yang berbeda, Gapoktan di Gang C memilih untuk secara mandiri mengembangkan Kampung Hidroponik, Gapoktan di Gang B lebih memilih untuk mengembangkan jaringan seluas-luasnya baik kepada pemerintah maupun swasta.
Treatment of Secondary Mitral Regurgitation in Heart Failure: A Shifting Paradigm in the Wake of the COAPT Trial
Authors: Schlendorf Kelly H , O’Leary Jared , Lindenfeld JoAnn
Published: July 2020

Secondary mitral regurgitation (MR) is common in patients with left heart dysfunction and it is associated with poor outcomes. Findings from the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) trial, published in 2018, suggest that in a subset of people with heart failure with secondary MR that persists despite optimization of guideline-directed medical therapies, there is now a role for percutaneous mitral valve repair using the MitraClip device. Defining which patients are most likely to benefit from MitraClip, and when, requires both a multidisciplinary approach centered on heart failure, as well as a recognition of the need for further research in this area.
Responsible leadership in management education: A design-based research study
Authors: Raatz Saskia , Euler Dieter
Published: July 2020

In recent years, the quality of management education in general, and particularly of MBA and Executive MBA programs, has been called into question. There are serious doubts about universities’ ability to give students the competencies they need to deal with complex problems in modern society. One part of the discussion focuses on ethical issues and the process through which students develop values and attitudes. In line with the economic crisis, there has been increasing interest in the development of learners’ attitudes to responsibility.

We report the results of a study that starts with an ambitious and yet ill-structured learning goal in a demanding educational practice area: How can pedagogical interventions in management education be designed to promote learners' attitudes to responsible leadership? As a starting point, there are neither consensual definitions of responsible leadership nor substantial theories available to design promising interventions. De-sign-based research (DBR) provides a structured process to deal with research problems, starting with innovative but imprecisely defined objectives and unknown ways to reach them.

We introduce the DBR design and describe the research process and results from a project conducted at St.Gallen University’s Executive MBA program. In close collaboration with practitioners, interventions evolved through multiple cycles of development, testing and refinement with the pursuit of theory-building and practical innovation.
Design principles as a bridge between contexts: From innovation in the science museum to transformation in formal education
Authors: Leonard Simon N. , Fitzgerald Robert N. , Kohlhagen Stuart , Johnson Mark W.
Published: July 2020

This paper responds to Euler's consideration of the use of design principles to bridge between knowledge production and practice design in the first issue of this journal; and particularly to the question he left open on how design principles should be formulated more concretely. It does so by extending the discussion of the use of Sandoval's approach of 'conjecture mapping'. In this discussion article, we reflect upon our own efforts at a related form of 'bridge building', specifically on work to span the gap in practice designs between the contexts of science museums and more formal education settings. Museums offer opportunities for educational innovation. The evidence of impact of such innovation on the more formal le- arning environments, however, has been limited. Teachers in formal settings, it appears, tend to adopt individual exemplar activities, but do not transfer the innovative approaches to their wider practice. The ambition of the project we examine here was to design teacher professional learning activities that allow participants to move beyond a focus on the specifications of a specific innovation and instead appreciate - to make concrete - the design principles in use. We will argue that conjecture mapping has been useful making design principles concrete but, in doing so, will point to the need for further research
STEM Practices: A translational framework for large-scale STEM education design
Authors: Lowrie Thomas , Leonard Simon , Fitzgerald Robert
Published: July 2020

Underpinned by the nation-wide Early Learning STEM Australia (ELSA) project, this practice illustration presents a design framework to respond to the challenges of scaling and sustaining a large design-based research project. The framework, known as STEM Practices Framework, is informed by work within the Learning Sciences which suggests that the interplay between project innovation and the wider educational reform priorities are critical to the sustainability and scalability of projects. The ELSA project responded to this by developing processes of developmental evaluation to parallel the design based research of the project. Emerging from that process was a design proposition that the object of the project, and the entire STEM education agenda, is not simply to improve educational practice, but to shift educational purpose. Specifically, the paper argues that STEM Practices represents a qualitative shift in purpose from the content bound traditions of science, technology, engineering and mathematics education towards developing a greater capacity to use practices in diverse STEM contexts. The STEM Practices Framework described here was developed to support educators and developers to implement the project innovations built on this understanding. The framework is in two parts: (1) an adaptation of Kemmis et al.’s (2014) practice architectures approach and the practice architectures that support and constrain those practices. (2) A heuristic for working with STEM practices in large scale implementation.

KONTRIBUSI PENDEKATAN SEMANTIK PADA PERKEMBANGAN PENELITIAN ALQURAN (STUDI PADA SKRIPSI MAHASISWA PRODI ILMU ALQURAN DAN TAFSIR FAKULTAS USHULUDDIN UIN SUNAN GUNUNG DJATI BANDUNG)
Authors: Zulaiha Eni , Radiana Aan
Published: July 2020

Artikel ini memfokuskan pada kontribusi kajian sematik pada perkembangan penelitian ilmu Alquran dan tafsir terutama pada pencarian makna kata tertentu dalam ayat Alquran di Prodi Ilmu Alquran dan Tafsir, Fakultas Ushuluddin, Universitas Islam Negeri Sunan GunungDjati Bandung. Objeknya mengkhususkan hanya pada skripsi Faisal Tian dengan judu lPendekatan Semantik tentang makna Riba dan Derivasi dalam Alquran sebagai protitype dari skripsi mahasiswa lain yang membahas kajian ini. Melalui kajian deskriptif tulisan ini menunjukan bahwa meski analisa semantik termasuk kajian baru dalam studi pencarian makna, namun kajian ini telah banyak menarik minat mahasiswa melakukannya terutama saat penulisan skripsi. Ini terlihat dari jumlah skripsi yang menggunakan semantik Alquran terus bertambah. Selain hal itu, kajian semantik juga telah memberikan kontribusi yang signifikan untuk pengembangan matakuliah Digitalisasi Alquran di Prodi tersebut. Hal utama lainnya dari kontribusi pengkajian terhadap istilah-istilah yang dianggap kunci dalam Alquran juga menjadi model baru dalam program Praktek Profesi Mahasiswa (PPM) di prodi ini. Hal ini menunjukan bahwa penelitian Alquran dan Tafsir dengan kajian semantik telah membuktikan interkoneksi ilmu, tetapi juga dapat memberikan sumbangan berarti pada kemajuan penelitian tafsir sebagai motor penggerak perkembanganilmu tafsir di masa mendatang.

The purpose of this study was to evaluate whether low-level laser therapy improves healing of the implant surgical site with clinical and biochemical parameters. Thirty patients with an edentulous space spanning a single tooth were selected. The patients were randomly allocated to 1 of 2 groups: control group and test group. The test group received laser energy at a power of 2 J/cm2 with a total of 4–6 J energy over each implant. Clinical parameters (implant stability quotient, probing index, modified sulcus bleeding index) and osteoprotegerin were assessed at baseline and follow-up intervals (2 weeks, 6 weeks, and 3 months). The test group showed significantly higher implant stability quotient than the control group at 2 weeks (57.93 ± 3.95 vs 35.67 ± 3.08; P < . 01) and 3 months (58.86 ± 3.75 vs 67.06 ± 3.78; P < . 01). A significant rise in osteoprotegerin levels of the test group (686.30 ± 125.36 pg/mL at baseline and 784.25 ± 108.30 pg/mL at 3 months; P < . 01) was seen contrary to significant decline in the control group (839.50 ± 249.08 pg/mL at baseline vs 415.30 ± 78.39 pg/mL at 3 months; P < . 01). Within the limitations of the study, the findings suggest that the healing of peri-implant hard and soft tissues may be enhanced with the use of low-level laser therapy as an explicit modality during the postoperative period.

The aim of this study was to characterize the mechanical properties of a bioactive-modified polyetheretherketone (PEEK) manufacturing approach for dental implants and to compare the in vitro biological behavior with titanium alloy (Ti6Al4V) as the reference. PEEK, PEEK with 5% hydroxyapatite (HA), PEEK with 5% beta-tricalcium phosphate (βTCP), and Ti6Al4V discs were produced using hot pressing technology to create a functionally graded material (FGM). Surface roughness values (Ra, Rz), water contact angle, shear bond strength, and Vickers hardness tests were performed. Human osteoblasts and gingival fibroblasts bioactivity was evaluated by a resazurin-based method, alkaline phosphatase activity (ALP), and confocal laser scanning microscopy (CLSM) images of fluorescent-stained fibroblasts. Morphology and cellular adhesion were confirmed using field emission gun-scanning electron microscopy (FEG-SEM). Group comparisons were tested using analysis of variance (Tukey post hoc test), α = .05. All groups presented similar roughness values (P > .05). Ti6Al4V group was found to have the highest contact angle (P < .05). Shear bond strength and Vickers hardness of different PEEK materials were similar (P > .05); however, the mean values in the Ti6Al4V group were significantly higher when compared with those of the other groups (P < .05). Cell viability and proliferation of osteoblast and fibroblast cells were higher in the PEEK group (P < .05). PEEK-βTCP showed the highest significant ALP activity over time (P < .05 at 14 days of culture). An enhanced bone and soft-tissue cell behavior on pure PEEK was obtained to the gold standard (Ti6Al4V) with equivalent roughness. The results substantiate the potential role of chemical composition rather than physical properties of materials in biological responses. The addition of 5% HA or βTCP by FGM did not enhance PEEK mechanical properties or periodontal cell behavior.

The aim of this systematic review and meta-analysis was to determine the efficacy of chlorhexidine (CHX) as an adjunctive therapy to mechanical debridement in the treatment of peri-implant diseases. Five databases (PubMed, EMBASE, Cochrane Central Register of Controlled Trails, Web of Science, and ClinicalTrials.gov) were searched. Randomized controlled trials (RCTs) comparing mechanical debridement combined with CHX to mechanical debridement alone for patients with peri-implant disease were identified. The trial investigators evaluated factors indicating inflammatory levels, including bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL). Six RCTs with 207 patients were ultimately included in this review. Low- to moderate-quality evidence demonstrated that the adjunctive CHX therapy had no significant effect on BOP reduction within 1 month (mean difference [MD], 0.10; 95% confidence interval [CI], −0.06 to 0.25), 3–4 months (MD, 0.06; 95% CI, −0.03 to 0.15), and 6–8 months (MD, 0.06; 95% CI, −0.03 to 0.14) of follow-up. Significant differences in PD reduction and CAL gain were also not found. Although 1 subgroup analysis revealed a significant result (MD, 009; 95% CI, 0.01–0.18) for the use of CHX solution, this could be interpreted as clinically slight. Based on available evidence, adding CHX to mechanical debridement, compared with mechanical debridement alone, did not significantly enhance the clinical results. Therefore, clinicians should consider the negligible effect of adjunctive CHX.
Osseodensified Crestal Sinus Window Augmentation: An Alternative Procedure to the Lateral Window Technique
Authors: Salgar Nilesh
Published: July 2020

A novel minimally invasive technique, osseodensification, is proposed to facilitate maxillary sinus bone graft augmentation. The osseodensified crestal window overcomes the previous limitations of traditional crestal approaches with respect to residual bone height (RBH) of ≤1.5 mm as well as vertical height of augmentation (>10 mm). Three patients, healthy and non-smoking, with 3 distinct and difficult clinical situations requiring sinus augmentation and having a maximum of 1.5 mm RBH (0.4–1.5 mm) were selected for this procedure. Edentulous sections were large (entire posterior sextant, with and without sinus septa), and small (single hyperpneumatized maxillary molar site). All healing was rapid and uneventful with no instances of sinus membrane perforation or other complications seen. The vertical increase in sinus bone height ranged from 10.3 mm to 13.6 mm. The increase in bone height is comparable to that obtained with lateral window procedures. The osseodensified crestal sinus window technique may be thus be proposed as a possible alternative procedure for the lateral sinus window technique for maxillary sinus bone augmentation.
The Effect of Hypothyroidism on Bone Loss at Dental Implants

Hypothyroidism (HT) is an endocrine disorder characterized by abnormally reduced thyroid gland activity and is most commonly of autoimmune etiology. HT is associated with alterations in bone metabolism, and HT patients typically experience decreased bone resorption. The objective of this study was to use dental implants as standardized reference markers to compare the extent of alveolar bone loss in implant patients with and without HT. We examined medical and dental history records and radiographic data from 635 patients receiving 1480 implants during 2000–2017. The rate of bone loss was calculated from differences in radiographic bone levels over time, corrected for radiographic distortion. Peri-implant bone loss from patients with HT was significantly lower than for those without HT (t1252= −3.42; 95% confidence interval= 0.47–1.73; P < .001; M = 0.53 and 1.63 mm/yr, respectively). A similar relationship persisted after excluding smokers and diabetics and after additionally excluding those on systemic steroids, hormone replacement therapy, hormone medications, or autoimmune diseases other than HT. Our data suggest that patients with HT have a decreased rate of bone loss around dental implants and may not be at increased risk for dental implant failure. The decreased bone metabolic rate among patients with HT might contribute to those findings.
The hyperloop challenge for tunnelling: higher productivity and lower costs
Authors: Grose Bill
Published: July 2020

Triggered by the potential challenges of providing supporting infrastructure for future very-fast ground-transport systems such as hyperloop, the British Tunnelling Society carried out a year-long research and thought-leadership project into ways of increasing productivity and reducing costs of tunnelling. This paper describes the research and its findings. It also lists tunnel projects that might become technically viable with greater productivity and lower costs. Proposals are made for the direction of future work, noting that a broader commitment from all stakeholders in tunnelling projects will be needed to achieve significant improvements.
