Authors: Kohansal Samin , Rostami Shoeyb , Rostami Zeynab
Published: March 2017

Corporate governance has been raised as one of the most important issues among the international business environment since the beginning of the twenty-first century. At first, corporate governance basic principles focused on firm’s strategies and the rights of their shareholders but these principles has been changed into the rights of all stakeholders and society through researchers new viewpoints. Although corporate governance codes and regulations are different in various countries, there is a common unanimity that better compliance of corporate governance improves financial reporting quality and transparency. The aim of this paper is to investigate the impact of corporate governance mechanisms on financial reporting transparency in Tehran Stock Exchange over a seven year period (from 2006 to 2012). Besides we have specially reviewed related researches and topics about corporate governance in various countries which their results were discussed in different parts of the article. In order to examine the hypothesis a sample of 67 companies is used. In this paper we used ownership concentration, institutional ownership, board independence, board size, CEO duality and CEO tenure as the corporate governance mechanisms. We also used earnings management behavior by employing Kasznik model (the absolute value of abnormal accruals) as a measure of financial reporting transparency. To test research hypothesis a multiple regression with estimated generalized least square method is employed. The findings indicate that ownership concentration, institutional ownership, board independence and CEO tenure has positively affected financial reporting transparency through earnings management behavior. On the other hand board size and CEO duality has negatively affected financial reporting transparency through earnings management behavior.
INTENTIONAL CRANIAL DEFORMATION IN THE PRE-COLUMBIAN NASCA CULTURE
Authors: Wanot Jakub
Published: March 2017

Presented article, based on the results of the latest archaeological research and the analysis of cataloged objects, provides a multi-faceted characteristic of the phenomenon of intentional and culturally conditioned cranial deformation in the pre- Columbian Nasca culture. In the light of interdisciplinary research and analysis of iconographic motifs we can notice that Nasca folks specifically identified themselves and recognized each other by particular physical attributes. Especially frontal-occipital cranial deformation is a dramatic example of the situational manipulation of ethnic identity. Results obtained in presented paper clearly demonstrate that the deformation methods and its objectives could be widely different, as well as not homogeneous within the southern coast of Peru.
SOCIO-THERAPY AND SELF-ESTEEM
Authors: Gawle-Wiernasz Małgorzata
Published: March 2017

The modern world is characterized, by constant and dynamic social, educational, and economic change. In such situation an individual person, especially a young one, is at risk of losing its ,,Ego“- identity. This risk is associated with the so-called „new freedom", which loses education based on timeless values such as: truth, goodness and beauty. This type of “liberation model” leads to the degradation of conscience, which, by its turn, leads to human tragedies characterized by a low sense self-respect, a number of pathologies, addictions to alcohol or drugs… Socio-therapy may be an antidote to mitigate or eliminate the negative norms and behavior in the environment and can be helpful (through empathic therapist interaction and appropriately selected therapeutic program) to strengthen the sense of one’s own identity.

Published: March 2017

AODV routing protocol facilitates changing and simple-to-setup network environment. It helps setting up a network without sufficient infrastructure, such as in disaster area. Development of AODV protocol has gathered a worldwide research interest. However, not many researches implement AODV routing protocol in real mobile nodes and real MANET. In addition, real implementation deals with other works concerning underlying protocol, firmware and hardware configuration, as well as detailed topology both in logical and physical arrangement. This work aims to implements Ad-hoc On-demand Distant Vector – particularly University of Indonesia AODV (AODV-UI) routing protocol on low-end inexpensive generic wireless routers as a proof of concept. AODV-UI is an improved version of AODV routing protocol that implements gateway interconnection and reverse route capability. This routing protocol has been previously successfully tested in NS-2. In this work, current AODV-UI protocol is ported to OpenWRT + MIPS (Microprocessor without Interlocked Pipeline Stages) little endian architecture then tested on the real networking environment. Underlying media access layer is also altered to provide the protocol greater control over the network. Performance of this implementation is measured in terms of energy consumption, routing overhead, end-to-end delay, protocol reliability and packet delivery ratio.
A Routing Protocol Based on Mobility Prediction for Mobile Ad Hoc Networks
Authors: Bisengar Ahmed
Published: March 2017

In Mobile Ad hoc Networks (MANETs), where nodes have limited transmitting power, the transmission is typically multi-hop. The network topology changes frequently due to the unpredictable movement of mobile nodes because each node is free to move arbitrarily with different speeds. Thus, when one node enters in the transmission range of another node a link between those two nodes is established, and an existent link is broken when either node is out of the transmission range of the other. We refer as link duration, the time interval during in which the link still established.This paper presents a novel mobility metric for mobile ad hoc networks, called link duration (LD) that measures the stability of an active link. This mobility metric is introduced to represent relative mobility between nodes in multi-hop distance.
Discovery and Mash-up of Physical Resources through a Web of Things Architecture

Published: March 2017

The Internet of Things has focused on new systems, the so-called smart things, to integrate the physical world with the virtual world by exploiting the network architecture of the Internet. However, defining applications on top of smart things is mainly reserved to system experts, since it requires a thorough knowledge of hardware platforms and some specific programming languages. Furthermore, a common infrastructure to publish and share resource information is also needed. In this paper, we propose a software architecture that simplifies the visual development and execution of mash-up applications based on smart things, exploiting Internet Web protocols and their ubiquitous availability even on constrained devices. We have developed a distributed architecture that allows to create and control mash-up applications in an easy and scalable way, without specific knowledge on both hardware and programming languages. In addition, we have also defined a centralized public database deployed on the Internet, to manage and share physical resource information. The effectiveness of the proposed framework has been tested through a real use case and experimental results have demonstrated the validity of the whole system.

Authors: Huang Rui , Wang Yubo , Chu Chi-Cheng , Gadh Rajit , Song Yu-jin
Published: March 2017

With the rapid development of wind turbine, photovoltaicand battery technologies, renewable energy resources such as wind and solar become the most common distributedgenerations (DG) that are being integrated into microgrids. One key impediment is to determine the sizes and placements of DGs within which the microgrid can achieve its maximum potential benefits. The objective of the paper is to study and propose an approach to find the optimal sizes and placements of DGs in a microgrid. The authors propose a comprehensive objective function with practical constraints which take all the important factors that will impact the reliability of the power grid into account. To solve the optimization problem, genetic algorithm (GA) is used and compared with a mathematical optimization method nonlinear programming. The proposed model is tested on a real microgrid, i.e. Jeju Island, to evaluate and validate the performances of the approach. The simulation results present the optimal configuration of DGs for Jeju Island power grid. The analysis on results shows that GA maintains a delicate balance between performance and complexity. It is concluded that GA performs better not only in accuracy, stability, but also in computation time.

Published: March 2017

this article presents a conceptual, architectural and organizational model for the realization of a smart city based on a holistic paradigm as its cornerstone and on the new technologies as its enabling tools. The model is based on the concept of integration of the data belonging to different systems, through the development of a middleware, which allows the retrieval of data from various sources and their storage in a standard format in a new centralized database. The article also illustrates a real project concerning the integration of different sensor networks for the environmental monitoring that exemplifies and implements the main topics discussed. The issues related to its "governance" are also highlighted, not only from a strategic point of view, but also, and above all, from the perspective of its maintenance, which is an important and crucial feature for its "survival" over time.
An Energy-Efficient MAC Scheduler based on a Switched-Beam Antenna for Wireless Sensor Networks
Authors: Catarinucci Luca , Guglielmi Sergio , Mainetti Luca , Mighali Vincenzo , Patrono Luigi , Stefanizzi Maria Laura , Tarricone Luciano
Published: March 2017

Wireless Sensor Networks (WSNs) are receiving an ever increasing attention because they are one of the most important technologies enabling the Internet of Things vision. Since nodes of these networks are battery-powered, energy efficiency represents one of the main design objectives. This goal can be primarily achieved through an optimization of the communication phase, which is the most power consuming operation for a WSN node. However, the limited computational and storage resources of physical devices make the design of complex communication protocols particularly hard, suggesting, on the contrary, to integrate more simple communication protocols with hardware solutions aimed at energy saving. In this work, a new MAC protocol, compatible with the IEEE 802.15.4 standard, and a reconfigurable beam-steering antenna are presented and validated. They significantly reduce the nodes’ power consumption by exploiting scheduling techniques and directional communications. Specifically, both during transmission and receiving phases, the node activates exclusively the antenna sector needed to communicate with the intended neighbour. The designed antenna and the proposed protocol have been thoroughly evaluated by means of simulations and test-beds, which have highlighted their good performance. In particular, the MAC protocol has been implemented on the Contiki Operating System and it was compared with the IEEE 802.15.4 standard solution.
Frequency and Time Domain Analysis of Influence of the Grounding Electrode Conductivity on Induced Current Distribution
Authors: Šesnić Silvestar , Poljak Dragan
Published: March 2017

The paper deals with an assessment of the influence of finite conductivity to the current induced along the horizontal grounding electrode. Analysis is performed in frequency and time domain, respectively. Current distribution along the grounding electrode buried in a lossy half-space is determined via analytical solution of the corresponding Pocklington equation in the frequency domain. The corresponding time domain response is obtained by means of Inverse Fast Fourier Transform (IFFT). The electrode is excited via an equivalent current source. Presence of the earth-air interface is taken into account via the simplified reflection coefficient arising from the Modified Image Theory (MIT). The electrode current is calculated for the case of perfectly conducting (PEC) electrode and for the electrodes made of copper and aluminum. Comparison of results shows no significant discrepancy between these electrodes, justifying the use of a PEC electrode approximation.
On Event Reproduction Ratio in Stateless and Stateful Replay of Real-World Traffic
Authors: Lin Ying-Dar , Lu Chun-Nan , Sagastume Jose Miguel , Hung Jui-Tsun , Lai Yuan-Cheng
Published: March 2017

Capturing and replaying network flows are important for testing network devices. Replayed traffic should reproduce effects similar to live traffic. This work presents methods to measure the event reproduction ratio, and studies the effectiveness of stateless and stateful traffic replayers based on the events triggered by packets and connections. We use two replayers, SocketReplay and Tcpreplay, and a networking device supporting security services. SocketReplay is a stateful replayer which keeps the state of a connection during replay, while Tcpreplay is a stateless replayer that ignores the connection state. Results indicate that SocketReplay replayed a smaller ratio of the captured traffic and triggered fewer blocking events in subsequent replay tests. Triggering blocking events denotes the replayed traffic cannot fit the onsite context. SocketReplay only replayed 38.74% of the captured TCP traffic, and resulted in an effectiveness of 99.97% (0.00%) in passing (blocking) event ratio. In contrast, Tcpreplay replayed 99.99% of the captured TCP traffic, and resulted in an effectiveness of 99.73% (75.64%) in passing (blocking) event ratio. The choice of a proper replayer and the corresponding replay configuration should depend on the contents of captured traffic and avoid to a significant drop of event reproduction ratio and the effectiveness of replayers.
MONITORING DAN EVALUASI PROGRAM BANTUAN OPERASIONAL SEKOLAH DI KOTA SALATIGA DENGAN MENGGUNAKAN ANALISIS KESENJANGAN TAHUN 2011/2012
Authors: Slameto Slameto
Published: March 2017

Monitoring dan evaluasi (monev) ini dilakukan untuk mengidentifikasi kesenjangan implementasi dan hasil Program Bantuan Operasional Sekolah (BOS) dengan mendasarkan hasil pengisian kuestioner dan Focus Group Discustion (FGP) dengan 24 orang stake-holder. Berdasarkan hasil analisis yang telah dilaksanakan diperoleh bahwa implementasi Program BOS di Salatiga ternyata terdapat kesenj angan yang bervariasi: tinggi, sedang dan rendah baik menyangkut proses implementasi maupun hasil program. Sesuai tujuan, ternyata dana BOS digunakan untuk mensubsidi seluruh siswa, mengurangi iuran yang dibebankan kepada orang tua siswa terutama yang miskin, diarahkan untuk membebaskan biaya pendidikan bagi siswa tidak mampu dengan tetap memperoleh layanan pendidikan yang lebih bermutu. Sesuai tujuan, hasil program BOS mencakup: BOS dapat menjadi akses untuk pengendalian pengelolaan dana pendidikan untuk menjamin penggunaan sumber daya finansial berlaku secara efisien, efektif, dan produktif; BOS memberi peluang bagi sekolah untuk membelanjakan pada kegiatan-kegiatan (baru) yang sebelumnya tidak terpenuhi dari sumber iuran bulanan. Terdapat kesenjangan yang tinggi dalam implementasi BOS, sehingga: ada keraguan apakah sekolah tetap dapat mempertahankan mutu pelayanan pendidikan apalagi harus
menyelenggarakan sekolah gratis; apakah BOS digunakan secara transparan, dan para guru dilibatkan; dengan BOS yang diterima, sekolah belum dapat membebaskan seluruh biaya sekolah (hanya dapat membebaskan 40-70 persen dari biaya sekolah), sehingga masih harus melakukan penggalian dana dari sumber lain; terdapat sejumlah kebutuhan program sekolah yang strategis
tetapi tidak dapat dibeayai oleh BOS; Dana BOS belum mampu mewujudkan sekolah gratis. Terdapat berbagai faktor, baik faktor internal sekolah maupun faktor eksternal; yang perlu mendapat perhatian dalam menentukan tindak lanjut, yaitu perlunya memodifikasi program terutama pada aras implementasi level sekolah dengan dukungan supra struktur birokrasinya.
PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE LEARNING TOGETHER UNTUK MENINGKATKAN KEAKTIFAN DAN HASIL BELAJAR SISWA KELAS XI B PADA MATA PELAJARAN PKN DI SMK PGRI II SALATIGA
Authors: Mediatati Nani
Published: March 2017

Hasil pengamatan peneliti terhadap pembelajaran PKn di kelas XI B SMK PGRI II Salatiga, nampak bahwa guru masih menggunakan metode ceramah dan tanya jawab dalam menyampaikan materi. Pembelajaran lebih berpusat pada guru dan menekankan pada pembelajaran secara individual, sehingga tingkat keaktifan siswa rendah (34,25% dari seluruh siswa di kelas ). Hal ini juga berdampak kepada rendahnya hasil belajar yang mencapai 62,17 persen siswa di bawah KKM ( 75 ). Terkait masih rendahnya keaktifan siswa serta rendahnya hasil belajar siswa tersebut, maka dilakukan PTK sebagai upaya untuk meningkatkan keaktifan dan hasil belajar siswa melalui penerapan model pembelajaran kooperatif tipe learning together, sebagai salah satu alternatif pembelajaran yang lebih tepat. Indikator keberhasilan yang ditetapkan dalam penelitian ini adalah keaktifan belajar siswa meningkat lebih dari 80 persen dari jumlah siswa dan hasil belajar siswa mencapai KKM (≥ 75) meningkat 100 persen. Selama proses pembelajaran menggunakan model pembelajaran kooperatif tipe learning together keaktifan belajar siswa dapat meningkat, karena siswa diberdayakan dan diberi kepercayaan untuk kritis dan terlibat aktif dalam kegiatan belajar. Ketercapaian persentase rata-rata keaktifan belajar siswa mencapai 71,4 persen pada siklus I yang lebih baik dari rata-rata keaktifan belajar siswa pada pra siklus yang hanya mencapai 34,25 persen saja, pada siklus II meningkat menjadi 91,4 persen. Dampak positif dari meningkatnya keaktifan belajar siswa adalah pada hasil belajar siswa yang juga meningkat, semula nilai rata-rata 72,43 pada pra siklus menjadi 75,86 pada siklus I dan 80,92 pada siklus II. Ketercapaian KKM (75), semula 37,83 persen pada pra siklus meningkat menjadi 81,08 persen pada siklus I dan menjadi 100 persen pada siklus II.

Pemecahan masalah (problem solving) merupakan bagian dari ketrampilan atau kecakapan intelektual yang dinilai sebagai hasil belajar yang penting dan signifikan dalam proses pendidikan. Signifikansi kecakapan pemecahan masalah itu dapat dilihat baik dari banyaknya perhatian berbagai aliran psikologi terhadap kecakapan intelektual ini, tingginya peringkat kecakapan itu dalam berbagai taksonomi hasil belajar, maupun dari posisi kecakapan ini dalam taksonomi disain pembelajaran. Terdapat banyak ragam pengertian maupun klasifikasi masalah. Dari segi cara pernyataannya masalah ada yang bersifat kebahasaan (lingustic), dan masalah yang bersifat bukan-kebahasaan (non-linguistic). Dari segi perumusan, cara menjawab dan kemungkinan jawabannya, masalah dapat dibedakan menjadi masalah yang dibatasi dengan baik (well-defined), dan masalah yang dibatasi tidak dengan baik (ill-defined). Ada juga yang membedakan menjadi masalah yang well-structured (distrukturkan dengan baik) dan masalah yang ill-structured (tidak distrukturkan dengan baik). Demikian juga terdapat banyak pendapat tentang proses pemecahan atas berbagai macam masalah yang ada tersebut. Ada yang berpendapat bahwa proses pemecahan atas masalah yang well defined maupun yang ill defined sama, namun ada juga yang berpendapat bahwa proses pemecahan kedua jenis masalah di atas berbeda.

On the study area there are three types of structure, those are fault, fold and joint. Types of fault were found  in the study area, reverse fault with the strike/dip is N215oE/75o, normal fault has a fault directions N22oE and N200oE with pitch 35o, and dextral fault with pitch 10o and strike N219oE. Fold and joint structures used to determine the direction of the main stress on the study area. Further, an analysis used stereonet for data folds and joints. So that from the data got three directions of main stress, those are Northeast – Southwest (T1), North – South (T2) and Southeast – Northwest (T3). On the Northeast – Southwest (T1) stress there are four geological structures, anticline fold at ST.3 , syncline folds at ST. 13a, ST. 13b, ST. 13c and ST. 33, chevron fold at ST. 44 and joint at ST. 2. On the North – South (T2) stress there are three geological structures, those are syncline fold at ST. 35, anticline fold at ST. 54 and joints at ST. 41, ST. 46 and ST. 47. On the Southeast – Northwest (T3) stress were also three geological structures, those are chevron fold at ST 42a, overturned fold at ST. 42b, syncline fold at ST. 42c and joints at ST. 5 and ST. 34.

Grinding operations are sometimes replaced with hard turning or milling cycles. Mechanism of chip separation during grinding and the corresponding surface integrity remarkably differs from hard turning or milling. For this reason, this paper deals with application of Barkhausen noise for evaluation of surface anisotropy after hard milling. Experiments were carried out on bearing steel 100CrMn6 hardened on 45, 55, 62 HRC and one series without heat treatment. The analysis contains comparison of RMS values for the different hardness and tool wear after hard milling and also discusses the specific mechanism of BW motion in the case of cyclic magnetization.

In the present computational study, the inclined angle effect of unsteady heat and mass transfer flow through salt water in an ocean was studied. The governing equations together with continuity, momentum, salinity and temperature were developed using the boundary layer approximation. Cartesian coordinate system was introduced to interpret the physical model where x-axis chosen along the direction of salt water flow and y-axis is inclined to x-axis. Two angle of inclination was considered such as 90° and 120°. The time dependent governing equations under the initial and boundary conditions were than transformed into the dimensionless form. A numerical solution approach so-called explicit finite difference method (EFDM) was employed to solve the obtained dimensionless equations. Different physical parameter was found in the model such as Prandtl number, Modified Prandtl number, Grashof number, Heat source parameter and Soret number. A stability and convergence analysis was developed in this study to describe the aspects of the finite difference scheme and this analysis is significant due to accuracy of the EFDM approach. The convergence criteria were observed to be in terms of dimensionless parameter as Pr ≥ 0.0128 and Ps ≥ 0.016. The distributions of the temperature and salinity profiles of salt water flow over different time steps were investigated for the effect of different dimensionless parameters and shown graphically.

Published: March 2017

One of the most best-known characteristic and important requirement of dental implant is made of biomaterials ability to create correct interaction between implant and human body. The most implemented material in manufacturing of dental implants is titanium of different grades of pureness. Since most of the implant surface is in direct contact with bone tissue, shape and integrity of said surface has great influence on the successful osseointegration. Among other characteristics of titanium that predetermine ideal biomaterial, it shows a high mechanical strength making precise machining miniature Increasingly difficult. The article is focused on evaluation of the resulting quality, integrity and characteristics of dental implants surface after machining.
Large time behavior of the logistic age-structured population model in a changing environment

Published: March 2017

Population growth is governed by many external and internal factors. In order to study their effects on population dynamics, we develop an age-structured time-dependent population model with logistic-type nonlinearity. We prove existence of a unique nonnegative bounded solution. Our main concern is to study asymptotic behavior of a solution in the general case, and especially for a periodic environment. We use the method of lower and upper solutions known in the theory of integral equations to formulate lower and upper boundaries of population density. In the periodic case, we discover a connection between the period of oscillation and its effect on population growth.
Mathematical justification of the obstacle problem for a piezoelectric shallow shell
Authors: Yan Guan , Miara Bernadette
Published: March 2017

In this paper we properly justify the modeling of a thin piezoelectric shallow shell in unilateral contact with a rigid plane. Starting from the three-dimensional nonlinear Signorini problem, we establish the convergence of the displacement field and of the electric potential as the thickness of the shell goes to zero. More precisely we obtain that the transverse mechanical displacement field coupled with the in-plane components solve an obstacle problem described new piezoelectric characteristics. We also investigate the very popular case of cubic crystals and show that, for two-dimensional shallow shells, the coupling piezoelectric effect disappears.

OBJECTIVE: To compare blood loss and the use for blood transfusion between elective (planned) and emergent cesarean hysterectomy performed for placenta accreta by a single, multidisciplinary team and to present the team’s pre-operative evaluation and the surgical technique.

STUDY DESIGN: Prospective cohort study at a single tertiary care center. Maternal and neonatal outcomes were compared between elective and emergent delivery of pregnancies complicated by placenta accreta. The primary outcomes were the need for blood transfusion and the number of units transfused.

RESULTS: A total of 28 cases of confirmed placenta accreta underwent peripartum hysterectomy, including 22 as elective and 6 as emergent. Eleven out of 22 (50%) subjects in the elective group received blood transfusion, while all subjects in the emergency group required transfusion ( p = 0.03). More importantly, the number of units of packed red blood cells transfused was only 1.90 (±2.20) units in the elective cases compared to 7.83 (±4.90) units in cases performed emergently ( p = 0.03).

CONCLUSION: Elective cesarean hysterectomy for this indication using a clearly outlined surgical approach is associated with significantly lower blood loss and hence less need for transfusion, compared to its emergent counterpart.
