Tujuan penelitian ini untuk meningkatkan mutu pembelajaran dan mutu guru melalui implementasi supervisi akademik. Metode penelitian yang digunakan adalah Penelitian Tindakan Sekolah (PTS) dengan pendekatan deskriptif kuantitatif. Teknik pengumpulan data dengan wawancara, studi dokumen dan observasi. Hasil penelitian menunjukkan bahwa supervisi akademik pada siklus 1 dan siklus 2 menunjukkan terjadi peningkatan skor pada aspek perencanaan dan pelaksanaan pembelajaran. Meskipun masih berada pada kategori cukup, namun dari pra siklus sampai dengan siklus 2 terus mengalami peningkatan. Hasil ini dapat dicapai karena adanya kerjasama yang baik antar Kepala Sekolah dan Guru yang disupervisi. Kepala Sekolah berdiskusi dengan guru mengenai masalah yang dihadapi guru pada proses perencanaan dan pelaksanaan pembelajaran. Supervisi akademik yang dilakukan Kepala Sekolah merupakan usaha untuk memperbaiki pengajaran, termasuk menstimulasi, menyeleksi pertumbuhan jabatan dan perkembangan guru- guru serta merevisi tujuan-tujuan pembelajaran, bahan pengajaran, metode, evaluasi atau penilaian pengajaran. Supervisi akademik dapat membantu guru untuk mempelajari dan memahami tugas dan perannya sebagai seorang pendidik. Implementation of academic supervision for increasing the quality of teachers AbstractThe aim of this study is to improve the quality learning of teachers through the implementation of academic supervision. The research method used is School Action Research (PTS) with a quantitative descriptive approach. Data collection techniques with interviews, document studies, and observations. The results showed that academic supervision in cycle 1 and cycle 2 showed an increase in scores on aspects of planning and implementing learning. Although it is still in a sufficient category, from pre-cycle to cycle 2 it continues to increase. This result can be achieved because of the good cooperation between the Principal and the supervised Teacher. Principals discuss with teachers about the problems faced by teachers in the planning and implementation of learning processes. Academic supervision by the Principal is an effort to improve teaching, including stimulating, selecting the growth of positions and the development of teachers and revising learning objectives, teaching materials, methods, evaluation and evaluation of teaching. Academic supervision can help teachers to learn and understand the task and its role as an educator.
Hexagonal management kelas dalam pembelajaran di sekolah dasar
Authors: Dike Daniel , Parida Lusila 
Published: April 2019

Penelitian ini bertujuan memetakan suatu gambaran pemanfaatan kelas sebagai episentrum pembelajaran secara maksimal melalui penguatan manajemen kelas. Disain penelitian ini menggunakan case study research. Penelitian ini mengkaji fenomena dan fakta pembelajaran di kelas melalui observasi partisipan, wawancara mendalam dan studi dokumentasi serta angket respon siswa terhadap aktivitas belajar mengajar yang dilakukan guru dan siswa di SD Panca Setya 2 Sintang, Kalimantan Barat. Data divalidasi dengan triangulasi sumber dan teknik kemudian dianalisis dan ditarik kesimpulan secara induktif. Hasil penelitian menunjukan bahwa kelas dan pembelajaran belum sepenuhnya menjadi pusat atau episentrum pembelajaran yang kuat meskipun pada aspek perencanaan, pengorganisasian, implementasi dan evaluasi belajar yang dilakukan guru sudah cukup baik. Respon siswa menunjukkan bahwa pada keempat aspek tersebut belum berjalan secara ideal sesuai harapan siswa kerena kelas belum sepenuhnya dikelola secara maksimal. Solusi mengatasi persoalan ini bisa dilakukan dengan menerapkan manajemen hexagonal yang memiliki enam kekuatan sentral yakni karakteristik siswa, sikap guru, infrastruktur kelas, infrastruktur teknologi, dukungan sekolah, dukungan yayasan atau dinas pendidikan. Bila pembelajaran di kelas mengintegrasikan peran sentral keenam aspek manajemen hexagonal maka kelas akan sungguh-sungguh menjadi pusat gravitasi pembelajaran efektif, produktif dan bermakna. Class hexagonal management in elementary school learning AbstractThis study aims to map a picture of class use as the epicenter of learning and strengthening classroom management. This research design uses a case study research. This study explores the phenomena and facts of learning in the classroom at Panca Setya 2 Elementary School, in Sintang of West Kalimantan. The data collecting by participant observation, in-depth interviews and documentation studies as well as student response questionnaires to teaching and learning activities carried out by teachers and students. Data is validated by source triangulation and techniques then analyzed and drawn inductively. The results of the research show that class and learning have not yet fully become the center or strong epicenter of learning even though the aspects of planning, organizing, implementing and evaluating the learning done by the teacher are good enough. Students' responses show that the four aspects have not run ideally according to student expectations because the class has not been fully managed maximally. The solution to overcome this problem can be done by implementing hexagonal learning management because it is believed to be able to turn on six key aspects of learning so that the class truly becomes the center of effective and optimal learning gravity.
A Web-Based and Print-Delivered Computer-Tailored Physical Activity Intervention for Older Adults: Pretest-Posttest Intervention Study Comparing Delivery Mode Preference and Attrition
Authors: Boekhout Janet Maria , Peels Denise Astrid , Berendsen Brenda Angela Juliette , Bolman Catherine , Lechner Lilian 
Published: April 2019

Background
Web-based interventions can play an important role in promoting physical activity (PA) behavior among older adults. Although the effectiveness of these interventions is promising, they are often characterized by low reach and high attrition, which considerably hampers their potential impact on public health.

Objective
The aim of this study was to identify the participant characteristics associated with the preference for a Web-based or a printed delivery mode and to determine whether an association exists between delivery modes or participant characteristics and attrition in an intervention. This knowledge may enhance implementation, sustainability of participation, and effectiveness of future interventions for older adults.

Methods
A real-life pretest-posttest intervention study was performed (N=409) among community-living single adults who were older than 65 years, with physical impairments caused by chronic diseases. Measurements were taken at baseline and 3 months after the start of the intervention. Hierarchical logistic regression was used to assess demographic and behavioral characteristics (age, gender, body mass index, educational attainment, degree of loneliness, and PA level), as well as psychosocial characteristics (social support for PA, modeling, self-efficacy, attitude, and intention) related to delivery mode preference at baseline and attrition after 3 months.

Results
The printed delivery mode achieved higher participation (58.9%, 241/409) than the Web-based delivery mode (41.1%, 168/409). Participation in the Web-based delivery mode was associated with younger age (B=–0.10; SE 0.02; Exp (B)=0.91; P<.001) and higher levels of social support for PA (B=0.38; SE 0.14; Exp (B)=1.46; P=.01); attrition was associated with participation in the Web-based delivery mode (B=1.28; SE 0.28; Exp (B)=3.58; P<.001) and low educational attainment (B=–0.53; SE 0.28; Exp (B)=0.59; P=.049).

Conclusions
A total of 41% of the participants chose the Web-based delivery mode, thus demonstrating a potential interest of single older adults with physical impairments in Web-based delivered interventions. However, attrition was demonstrated to be higher in the Web-based delivery mode, and lower educational attainment was found to be a predictor for attrition. Characteristics predicting a preference for the printed delivery mode included being older and receiving less social support. Although Web-based delivery modes are generally less expensive and easier to distribute, it may be advisable to offer a printed delivery mode alongside a Web-based delivery mode to prevent exclusion of a large part of the target population.

Authors: Mak Ka-Hi May , Kippist Louise , Sloan Terry , Eljiz Kathy 
Published: April 2019

Objective: This paper explores the professional identity (PI) of Allied Health Managers (AHMs) and how their identity is typically constructed.
Methods: A qualitative research methodology utilising semi-structured interviews was employed for this research. Thematic analysis was used to extract relevant data from the transcripts.
Settings: The study was undertaken in five acute hospitals within one of the largest metropolitan Local Health Districts in New South Wales, Australia. A total of sixteen AHMs and deputy AHMs were interviewed.
Results: Three key themes identified were: PI of AHM, motivation of becoming a manager, and construction of their identity. Factors motivating AHMs to follow a management pathway were identified as being a natural progression and having interest in high-level decision-making. Despite AHMs sharing similar role conflict as the medical managers, they adapted to hybrid manager roles with minimal resentment. They also adopted to the hybrid manager role with a positive, realistic and flexible perspective.
Conclusion: Despite facing role conflict as a hybrid-professional-manager, AHMs manage the transition from clinicians to managers with a positive approach. This indicates that AHMs may require certain skills or characteristics to successfully construct their PI.
Structure and Properties of Polyacrylonitrile/Polystyrene and Carbon Nanoparticle-Based Nanocomposite Foams
Authors: Kausar A. 
Published: April 2019

Abstract
In this study, novel polyacrylonitrile/polystyrene (PAN/PS) blend has been prepared and reinforced with carbon nanoparticle to form polyacrylonitrile/polystyrene/carbon nanoparticle (PAN/PS/CNP) nanocomposite foam. Acid-functional carbon nanoparticle (0.1-3 wt.%) was used as nano-reinforcement for PAN/PS blend matrix. 2’-azobisisobutyronitrile was employed as foaming agent. The PAN/PS/CNP nanocomposite foams have been tested for structure, morphology, mechanical properties, thermal stability, non-flammability, water uptake, and toxic ion removal. Field-emission scanning electron microscopy and transmission electron microscopy exposed unique nanocellular morphology owing to physical interaction between the matrix and functional CNP. PAN/PS/CNP 0.1 Foam with 0.1 wt.% nanofiller had compression strength, modulus, and foam density of 41.8 MPa, 22.3 GPa, and 0.9 mgcm−3, respectively. Nanofiller loading of 3wt.% (PAN/PS/CNP 3 Foam) considerably enhanced the compression strength, modulus, and foam density as 68.2 MPa, 37.7 GPa, and 1.9 mgcm−3, respectively. CNP reinforcement also enhanced the initial weight loss and maximum decomposition temperature of PAN/PS/CNP 3 Foam to 541 and 574 ºC, relative to neat foam (T0 = 411 ºC; T10 = 459 ºC). Nanocomposite foams have also shown excellent flame retardancy as V-0 rating and high char yield of up to 57% were attained. Due to hydrophilic nature of functional carbon nanoparticle, water absorption capacity of 3 wt.% nanocomposite foam was 30% higher than that of pristine foam. Moreover, novel foams were also tested for the removal of toxic Pb2+ ions. PAN/PS/CNP 3 Foam has shown much higher ion removal capacity (166 mg/g) and efficiency (99 %) than that of PAN/PS foam having removal capacity and efficiency of 90 mg/g and 45 %, respectively.
The Influence of Laser Alloying of Ti13Nb13Zr on Surface Topography and Properties
Authors: Tęczar P. , Majkowska-Marzec B. , Bartmański M. 
Published: April 2019

Abstract
The laser alloying is a continually developing surface treatment because of its significant and specific structuration of a surface. In particular, it is applied for Ti alloys, being now the most essential biomaterials’ group for load-bearing implants. The present research was performed on the Ti13Nb13Zr alloy subject to laser modification in order to determine the treatment effects on surface topography and its some mechanical properties like nanohardness, Young’s modulus, roughness. A pulse laser Nd:YAG was applied at three different laser pulse regimes: either 700 W, 1000 W or 1000 W treatment followed by 700 W modification at a pulse duration of 1 ms. The surface topography and morphology were examined using light microscopy and scanning electron microscopy with spectroscope of X-ray energy dispersion. The mechanical properties were determined by nanoindentation tests and surface roughness with a use of profilograph. The wettability was tested with a goniometer. The obtained results demonstrate complex behavior of the material surface: decrease in penetration distance and increase in hardness after first laser treatment, maintenance of this trend when machining using a higher laser pulse power, followed by an increase in penetration and decrease in hardness after additional laser treatment at lower power input, due to which a surface with fewer defects is obtained. The change in Young’s modulus follows the change in other mechanical properties, but not a change in roughness. Therefore, the observed hardening with the increase of the laser pulse power and then a small softening with the use of additional treatment with lower power can be attributed to some processes of remelting, diffusion and crystallization, sensitive to the previous surface state and heat energy flux. Despite that, the laser treatment always caused a significant hardening of the surface layer.
Microstructure Characterization of Welds in X5CrNiCuNb16-4 Steel in Overaged Condition

Published: April 2019

Abstract
The paper presents the results of the investigation of microstructure of the welded X5CrNiCuNb16-4 (17-4PH) steel after solution treatment and aging at 620°C for different periods. The microstructure and the phase composition of the steel was investigated using light microscopy (LM), scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), transmission electron microscopy (TEM) and the X-ray diffraction (XRD). Hardness was measured for samples aged at different times. Density distributions of Cu precipitates were established. The investigation has shown that the microstructure of the X5CrNiCuNb16-4 steel welds after aging at 620 ° C consists of tempered martensite, fine Cu precipitates and austenite. It was observed that the size of the Cu precipitates increases with increasing the aging time, what affects the decrease of hardness. Simultaneously, the quantity of reversed austenite increases with increase of aging time. It was revealed that enrichment of the austenite in Ni, Cu and C affects the increase of Ms, but this factor does not determine the stability of austenite.

Abstract
The aim of the study was to find associations between the process of neoplastic transformation and mtDNA mutations/polymorphisms, i.e. factors with potential prognostic significance, and to determine their impact on the biochemical properties, as well as structural, and functional properties of proteins. Blood and neoplastic tissue samples were collected from a 9-year-old Labrador dog with a diagnosed malignant mammary tumour. Next-generation genome sequencing (NGS) of the entire mitochondrial genome was performed using Illumina technology, and bioinformatics analyses were carried out. This is the first report demonstrating the application of NGS in the analysis of the canine mtDNA genome in neoplastic disease. The proposed strategy is innovative and promising. For the first time in the literature, the sequence of 29 genes was analysed to determine their association with the prevalence of tumour. In total, 32 polymorphic loci and 15 mutations were identified. For the first time, as many as 24 polymorphisms and all the mutations have been described to be associated with the neoplastic process in dogs. Most polymorphisms/mutations were found in the D-loop (31% of the polymorphisms and 93% of the mutations) and the COX1 gene sequence (16% of the polymorphisms). Blood or cancer heteroplasmy was noted in 93% of the mutations. Four of the 18 polymorphisms detected in the protein-coding genes were non-synonymous polymorphisms that have not been described in the literature so far (m.T7593C in COX2, m.G8807A in COX3, m.A9911G in ND4L, and m.T13299A in ND5) but resulted in changes in amino acids in proteins. These mutations and polymorphisms can affect mitochondrial functions and may be a result of cell adaptation to the changes in the environment occurring during carcinogenesis. The replacement of “wild type” mtDNA by a mutated molecule may be an important phenomenon accompanying carcinogenesis.
