Published: January 2019

Stress is one of the psychological reactions that can be in a work situation. Work situations may change at any time in different forms. An employee's psychological reaction to change also varies. Job insecurity arising from changing work situations increases job stress. A company certainly does not want employees to experience work stress that can impact on the decline in company performance. The level of employeereligiosity is expected to reduce the impact of job insecurity. This study aims to determine the role of job insecurity against work stress moderated by religiosity. Job stress as dependent variable, job insecurity as independent variable, and religiosity as moderator. Methods of data retrieval were performed using work stress scale, job insecurity scale, and scale of religiosity. The subjects of this study were 119 employees working in the State Forestry Corporation.

ALIANÇA DO PACÍFICO: UMA VISÃO DO BLOCO ATRAVÉS DO MODELO GRAVITACIONAL
Authors: Ortiz Pablo Chaves , Azevedo André Filipe Zago de
Published: January 2019

A partir da década de 1990, houve uma proliferação de Acordos Preferenciais de Comércio (APC) ao redor do mundo. Dentro deste cenário de mudança do comércio mundial, a América Latina foi um importante ator na criação de novos acordos. Entretanto, devido a histórica instabilidade política e econômica da região, nunca houve uma integração completa, devido principalmente ao caráter protecionista dos países. Nesse sentido, a Aliança do Pacífico (Chile, Colômbia, Peru e México) vem com uma proposta de integração econômica diferente, com objetivo de unir suas economias ainda mais e estar aberta às negociações comerciais com terceiros países. O objetivo deste estudo é estimar e comparar o comércio bilateral potencial entre os países membros da Aliança do Pacífico (AP), por meio de um modelo gravitacional de comércio por meio de dados em painel com efeitos fixos para o ano de 2002 e 2013, com uma amostra de 98 países. Os resultados mostraram que o comércio estimado para o ano de 2002 ficou 30% acima do efetivo, mostrando que havia um comércio potencial a ser explorado. No entanto, em 2013, eles já haviam convergido, com o comércio estimado inclusive ficando 1,2% abaixo do comércio efetivo. Isso parece demonstrar que a liberalização comercial dos membros da AP, ocorrida antes mesmo de sua formação, contribuiu para que o comércio potencial e o efetivo convergissem.

Published: January 2019

Background and Objectives: The purpose of this study was to determine the association of students’ race and gender with the race, gender, age, patient numbers, and problems encountered during a third-year family medicine clerkship across a geographically distributed clinical teaching network.
Methods: Student patient experience logbook data from two separate but adjacent 3-year periods were analyzed. Mixed-effects regression models and generalized linear mixed models were used to determine the relationship between student race and gender on number and demographics of patients encountered and odds of encountering required conditions and gender-specific conditions at least once during the clerkship.
Results: A total of 458 students documented 66,752 encounters during academic years 2008 through 2010, and 498 students documented 70,213 encounters during academic years 2011 through 2013. The first cohort averaged 145.8 (SD 24.0) encounters per student and the second cohort averaged 141.1 (SD 19.5) encounters per student. Females had more encounters during the first period, but no difference in the second. There was no difference in average encounters between white and nonwhite students during the first period, but during the second, nonwhite students had more encounters. A few differences were found in odds of encountering required conditions or gender-specific conditions, but none were consistent across time.
Conclusions: Family medicine clerkship students in this geographically distributed network did not experience significant differences in patient demographics, conditions, or gender-specific diseases, based on their gender or race. The teaching sites in the study were monitored continuously to ensure consistent clinical experiences in volume and scope.
Matching Our Mission: A Strategic Plan to Create a Diverse Family Medicine Residency
Authors: Wusu Maria Harsha , Tepperberg Suki , Weinberg Janice M. , Saper Robert B.
Published: January 2019

Background and Objectives: Increasing the number of underrepresented minority (URM) physicians improves access and quality of care. URMs are more likely to practice primary care and work in underserved communities. The racial and ethnic diversity of family physicians lags behind the general population. To create a more diverse residency, the Boston Medical Center Family Medicine Residency Program (BMCFMRP) developed, implemented, and evaluated a strategic plan for diversity recruitment.
Methods: In academic year (AY) 2014-2015, we set goals to increase the number of URM applicants and the percentage of matched URMs. From 2014-2017, we implemented an intervention focused on: (1) increasing outreach to URM candidates, (2) revising interviews to minimize bias, and (3) analyzing recruitment data.
Results: From 2014-2017, the total number of URM applicants increased by 80% (61 to 110). Evaluating recruitment trends from 2010-2017, there was a statistically significant increase (P<0.001) in the percentage of URM applicants from 13.3% (29 of 218 total applicants) to 19.9% (110 of 402). There was also a significant increase (P=0.029) in the percentage of matched URMs. Before the intervention, the percentage ranged from 0% to 20% (2011: 0% [n=0/6], 2014: 0% [n=0/10], 2013: 20% [n=2/10]). During the intervention, the percentage ranged from 25% to 50% (2017: 25% [n=3/12], 2016: 50% [n=6/12]).
Conclusions: The implementation of a strategic plan for diversity recruitment increased the number of URM applicants and the percentage of URMs matching into the BMCFMRP. Additional research is needed to determine if these strategies produce similar results in residency programs at other institutions and in other medical specialties.

Laser cleaning of metallic alloys for the purpose of removal of metal oxide layers is based on laser thermal ablation. In laser thermal ablation, the interaction between the laser beam and oxide layer may generate significant thermal effects to induce additional thermal oxidation or even melting a thin layer of the underlying surface. The change of surface oxide status may subsequently affect corrosion behavior of the metallic alloys. In this work, the effects of laser cleaning on corrosion behavior of hot-rolled AA5083-O aluminum alloy were investigated using electrochemical impedance spectroscopy. The results showed that the laser-cleaned surfaces exhibited higher corrosion resistance in 3.5 wt. % NaCl solution than the as-received alloy, with a significant increase in impedance and reduction in capacitance. The corrosion behavior was correlated to the change of surface oxide status measured by glow discharge optical emission spectrometry, x-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy. It was concluded that the laser cleaning removed the original, less protective oxide layer consisting of a discontinuous MgO/MgAl2O4 outer layer (∼20 nm) and MgO/MgAl2O4 particles dispersed inner layer (∼300 nm) on the as-received surface but resulted in the formation of more protective oxide layer containing mainly Al2O3 and MgO, which were responsible for the improvement of the corrosion performance. The laser fluence played an important role in determining the thickness of the newly formed oxide layers that subsequently affected the corrosion performance of laser-cleaned alloy.

The aim of this in vitro study was to assess the microshear bond strength (μSBS) of an adhesive system in sound (SD) and demineralized dentin (DD) after femtosecond (fs) laser treatment. Twenty specimens of human dentin were randomly divided into two main groups: sound and demineralized dentin (n = 10). In each of them, three different tissue conditions were produced: SD control group, SD etched with two different fluences of an fs laser (11 and 18 J/cm2, SD11 and SD18, respectively), DD control group, and DD irradiated with the same laser parameters (DD11 and DD18). An adhesive system was applied to the dentin surface, and a resin composite was light-cured to bond to the dentin surface. The μSBS was measured, and the fracture analysis was performed using an optical microscope. The data were analyzed using the Mann Whitney test (p < 0.05). Tissue morphology was assessed via 2D and 3D optical coherence tomography images, scanning electron microscopy, and atomic force microscopy. The optimum bond strength was recorded for the SD11 group (16.42 ± 4.63 MPa), and the minimum bond strength was recorded for the DD (8.89 ± 0.99 MPa) group. The Kruskal Wallis test revealed that sample groups were significantly different (p < 0.01). The Mann Whitney test demonstrated statistical differences between DD and all the other groups. The imaging techniques showed the opening of the dentinal tubules and that the bond strength could be related to laser-induced roughness. Femtosecond laser radiation was successfully able to remove smear layers, producing surface alterations that caused higher dentin-resin adhesion.

Authors: Affandi Rosnani , Omar Zamali
Published: January 2019

Mobile applications which are also known as mobile apps is a software program which is developed for mobile devices such as smartphone and tablets. Recently, the development of mobile apps for the educational purpose has been expanding rapidly. It becomes as one of a powerful tool for transforming learning and for improving the quality of education, enhancing the student understanding, helping affirm as well as advance the relationships between educators and students. Among the incredible number of mobile apps, there are a large number of apps for educational purposes. However, there is still a lack of mobile apps which focus on enhancing student understanding in Practical Work (PW). PW is important and plays a central role in Technical and Vocational Education and Training (TVET). It is because PW can develop hand on skill and at the same time as a bridging between theory and practice. However, most of the student cannot do well in PW because; students are not interested to read lab sheets, lack on preparation as well as lack on the understanding in theory which is related to PW. Therefore, P_Lab is developed with aim for enhancing the student understanding in the PW. P_Lab is a mobile app that is developed from AppMakr.com which is a do-it-yourself platform and the process requires less coding knowledge. To study the effectiveness of the P_Lab, pre-test, post-test and a questionnaire has been given to the Electrical Engineering student in Politeknik Melaka. Results showed that students made extensive use of resources provided from P_Lab, considered the P-Lab to be beneficial for enhancing their understanding in practical work, and found that it is easy to use with minimal support and training. An analysis showed a statistically significant increase in understanding scores for practical work-related questions after the introduction of P_Lab mobile app.

Interpretation of 2D-subsurface rock resistivity data has been carried out in the iron ore prospect area of Eastern Binangun Coastal in ​​Cilacap Regency, Central Java. The background of this research is the potential for abundant iron sand in this area that prospects to be exploited. The research was conducted using a magnetic method in 2017 to map the distribution patterns of the local magnetic anomalies that were interpreted to originate from the distribution of iron ore in the subsurface. In 2018, the research continued using the 2D-resistivity method to find out the lithology section in the subsurface of research area. 2D-resistivity data acquisition is carried out on four tracks consisting of Bng-01 to Bng-04. The resistivity data modeling have produced the true resistivity value for each track in the form of the subsurface resistvity section, which including the Bng-01 track is 2.27 – 44.1 Ωm; the Bng-02 track is 4.5 – 58.6 Ωm; the Bng-03 track is 6.37 – 63.4 Ωm; and the Bng-04 track of 4.98 – 83.3 Ωm. After interpretation process, some models of subsurface rocks lithology section is obtained under the four trajectories. The rocks resulted from interpretation process consists of sand which inserted with gravel (> 58.6 Ωm); sand containing iron ore grains (28.2 – 83.3 Ωm), clayey sand (11.1 – 32.9 Ωm), sandy clay (4.98 – 13.5 Ωm), and fine sand which intruded by saltwater (<6.49 Ωm). Sand containing iron ore grains is main part of the coastal aquifer so that exploitation of iron sand has the potential to reduce aquifer function in storing and flowing of groundwater and causing of abrasion in the Eastern Binangun Coastal area.
Testing the pecking order model of corporate leverage: An empirical investigation of Turkish firms
Authors: KALASH İsmail
Published: January 2019

This research
investigates the pecking order model of corporate leverage for a sample of 53
Turkish industrial firms listed on Istanbul stock exchange during the period
from 2008 to 2017. The study tries to concentrate on the predictions about how
corporate leverage varies with investments, profitability, risk, firm size and
tangibility. The coefficients of corporate leverage determinants are estimated
by using Ordinary Least Squares and Binary Logistic regressions. Confirming the
pecking order model, it is found that firms prefer to use internal cash flows
over external financing to fund investments. Moreover, the empirical results
also show that more profitable and risky firms tend to borrow less. On the
other hand, firms with more investments and larger firms tend to have more
leverage. The findings of this study will help the managers to design a better
strategy about capital structure which can maximize firm’s performance.

Authors: Sztubecki Jacek , Bujarkiewicz Adam , Derejczyk Karol , Przytuła Michał
Published: January 2019

The article presents the technology and an analysis of results of engineering structure displacements and deformation measurements. Two measuring technologies using the TDRA65000 laser station from Leica and the FARO Focus M scanner were applied during the tests. Use of the laser station enabled us to define horizontal and vertical displacements of a control network established on the tested facility. Owing to this, it was also possible to transform scanner measuring stations into one integrated unit. The described measurement methodology ensures a high accuracy of scanner station fitting which translates directly into the accuracy of determination of deformations in structural components of a facility. Integration of methods applied in the tests makes it possible to monitor not only displacements of control network points but also the structure as a whole in a uniform coordinate system.

Radiasi gelombang elektromagnetik mempengaruhi kualitas sperma, yaitu menurunkan motilitas (daya gerak) dan viabilitas (daya tahan). Mencit (Mus musculus) dapat digunakan sebagai hewan percobaan dikarenakan sistem reproduksinya hampir sama seperti manusia. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh medan listrik statis terhadap gerak acak dan daya tahan sperma mencit dalam keadaan ex vivo. Sperma mencit yang telah diencerkan dengan larutan fisiologis NaCl 0,9% dimasukkan ke dalam hemasitometer  yang  diletakkan diantara dua plat besi yang dihubungkan dengan sumber tegangan DC. Jarak antara kedua plat adalah d = 7,5 cm dan besar tegangan  sumber (ΔV = 0 V dan ΔV = 12,5 V). Pergerakan sperma diamati menggunakan mikroskop flouresensi kemudian direkam dengan menggunakan software NIS  elements. Sperma tanpa medan listrik (ΔV = 0) memiliki daya tahan selama 60 menit lebih lama dibandingkan sperma yang dipengaruhi medan listrik (ΔV = 12,5 V), hanya memiliki daya tahan selama 30 menit. Sperma bergerak acak ke segala arah apabila tanpa pengaruh medan listrik, akan tetapi sperma bergerak acak dan cenderung bergerak ke plat positif apabila berada dalam pengaruh medan listrik. Kualitas sperma normal dicirikan memiliki sperma yang bergerak zig-zag dan cepat sebesar 25%.

Abstract: Subsoil (sub grade) is the lowest layer in highway construction. The reliability of the pavement thickness design is highly dependent on the accuracy of the carrying capacity of the ground. The carrying capacity of the foundation soil known in the value of California Bearing Ratio (CBR) can be determined by Dynamic Cone Penetrometer (DCP) equipment. The working principle of DCP is very simple and economical in the field. However, since 2013 the Ministry of Public Works has issued a 2013 Pavement Design Destruction Manual (MDP) which requires the use of CBR values from laboratory test results with 4 day immersion samples. The problem that occurs is the time and cost of testing the sample. CBR immersion with 4 days of immersion will take longer. The cost of sampling, sample preparation and sample testing are also more expensive than testing with DCP tools. With this background, this study aims to find an empirical relationship between the value of ground support capacity (CBR) of both tools (DCP and CBR immersion). This research is a preliminary study of Road Laboratory of Faculty of Engineering Unsyiah and is expected to be developed by multiplying future research samples for more precise results. Empirical values obtained after the research is: CBR Dcp = 1.083 + (0.347 x CBR Lab) Abstrak: Tanah dasar (sub grade) merupakan lapisan terbawah pada konstruksi jalan raya. Kehandalan disain tebal perkerasan sangat tergantung pada keakuratan nilai daya dukung tanah dasar. Daya dukung tanah dasar yang dikenal dalam nilai California Bearing Ratio (CBR) dapat ditentukan dengan peralatan Dynamic Cone Penetrometer (DCP). Prinsip kerja DCP sangat sederhana dan ekonomis dilakukan di lapangan. Namun, sejak tahun 2013 Kementerian Pekerjaan Umum mengeluarkan Manual Disain Tebal Perkerasan (MDP) 2013 yang menyaratkan penggunaan nilai CBR dari hasil uji laboratorium dengan sampel rendaman 4 hari. Permasalahan yang terjadi adalah waktu dan biaya pengujian sampel. CBR rendaman dengan 4 hari perendaman akan memakan waktu yang lebih lama. Biaya pengambilan sampel, penyiapan sampel dan pengujian sampel juga lebih mahal dibandingkan dengan pengujian dengan alat DCP. Dengan latar belakang tersebut, maka penelitian ini bertujuan untuk mencari hubungan secara empiris antara nilai daya dukung tanah dasar (CBR) dari kedua alat tersebut (DCP dan CBR rendaman). Penelitian ini merupakan studi awal dari Laboratorium Jalan Raya Fakultas Teknik Unsyiah dan diharapkan dapat dikembangkan dengan memperbanyak sampel penelitian dimasa mendatang untuk hasil yang lebih presisi.  Nilai empiris yang didapatkan setelah dilakukan Penelitian adalah : CBR Dcp = 1.083 + (0.347 x CBR Lab)

Abstract: Generally, brick masonry is used as infill wall material for houses and buildings. The Infill wall is installed once the structure is constructed, and assumed as the dead load for the structure. In fact, infill wall may contribute significant stiffness to the structure. As a consequent, the structure may develop such higher base shear forces due to the large stiffness of the structure. The purpose of this research is to evaluate the behavior of the reinforced concrete frame specimen with red brick infill wall and the specimen without using any infill wall. The size of the frame specimen is 2350 x 3300 mm, which consists of reinforced concrete bare frame specimen and reinforced concrete frame specimen with brick masonry infill wall. Cyclic loading tests were conducted on the specimens on the top beam of frame by in-plane direction. The displacement loading protocol are performed laterally and determined by the measured maximum of LVDT from the beam-column connection. Based on the experimental result, the increase capacity and the obtained energy dissipation of the infill wall frame specimen is up to 11.65 and 3.54 higher respectively, compared to the bare frame specimen. The decrease of the stiffness and the ductility level of the infill wall specimen is lesser in comparison with the bare frame specimen. The typical failure mechanism of the infill wall specimens is diagonal cracking. Abstrak: Material bahan bangunan pengisi dinding untuk pembangunan rumah tinggal dan gedung umumnya menggunakan bata merah. Dinding pengisi dipasang apabila struktur utama selesai dikerjakan dan dianggap sebagai beban mati. Namun pada kenyataannya struktur bangunan yang memiliki dinding mempunyai kekakuan struktur yang besar. Ditinjau dari aspek kegempaan, struktur bangunan dengan kekakuan yang besar maka semakin besar pula beban gempa yang bekerja. Tujuan dari penelitian ini menganalisis perilaku portal beton bertulang dengan dinding bata merah yang dibandingkan dengan portal beton bertulang tanpa dinding. Pengujian yang dilakukan adalah portal beton bertulang dengan ukuran 2350 × 3300 mm berjumlah 2 sampel yaitu: portal tanpa dinding dan portal berdinding bata merah dengan plasteran. Pengujian portal dilakukan dengan beban lateral siklik dengan arah pembebanan sejajar bidang balok (in plane) pada balok bagian atas portal. Mekanisme pembebanan dilakukan dengan kontrol beban yang ditentukan oleh perpindahan maksimum yang terukur dari LVDT dari join kolom-balok. Hasil penelitian ini menunjukkan terjadinya peningkatan kapasitas dan energi disipasi sebesar 11,65 kali dan 3,54 kali dari portal tanpa dinding. Penurunan kekakuan dan daktilitas yang terjadi lebih kecil dari portal tanpa dinding. Pola kehancuran yang terjadi pada portal berisi dinding bata merah yaitu jenis diagonal cracking
