Partiendo de la necesaria situación de establecer un nuevo sistema que respondiera de manera real y efectiva a la crisis de justicia y la mora que se venía presentando en las causas criminales, se hizo necesaria la adopción del nuevo Sistema de Procedimiento Penal de corte acusatorio, en el cual se destaca el protagonismo de la figura del Juez con funciones de Control de Garantías, que asume la tarea de garante de los derechos fundamentales del investigado así como de las víctimas.La difícil labor de lograr un equilibrio entre la realización de la justicia y la de asegurar la protección real de los derechos fundamentales de los sujetos procesales, es una responsabilidad que se evidenciará especialmente con el actuar de estos jueces. Ellos estarán sujetos entonces a la ponderación entre la persecución efectiva de las conductas delictivas, labor que representa el interés legítimo del Estado, y la salvaguarda de los derechos constitucionales que les asisten a quienes tienen la calidad de imputados, principalmente. Todo esto obliga a analizar cuál es la tendencia que en la práctica se mostrará con una mayor prevalencia respecto de estos dos puntos especialmente definitivos a la hora de evaluar la eficacia del Sistema Procesal Penal Acusatorio.

La víctima en estos momentos se enfrenta a una coexistencia de sistemas procesales, en donde su participación en cada uno resulta muy diferente debido a la naturaleza de cada uno de los procesos. En el primer sistema, la víctima adquiere la calidad de sujeto procesal constituyéndose en Parte Civil; mientrasque en el segundo, es considerado como un interviniente especial en el proceso. Este artículo nos presenta la participación de la víctima en cada uno de los sistemas, con el fin de permitirnos establecer cuál de los dos sistemas resulta más garantista.

Cuando los contribuyentes de renta, personas naturales, se ven abocados a un proceso sancionatorio, adelantado por la DIAN, éstos por lo general no conocen el procedimiento a seguir, ignorando algunos los derechos que tienen. Este proceso debe garantizarle los derechos del contribuyente establecidos en el artículo 29 Constitución Política que son:La defensa y la asistencia de un abogado escogido por él, o de oficio, durante la investigación y el juzgamiento;Un debido proceso público sin dilaciones injustificadas; Presentar pruebas y controvertir las que se alleguen en su contra; Impugnar la sentencia condenatoria, yNo ser juzgado dos veces por el mismo hecho.Este artículo trae la “presunción de inocencia”, que en esta investigación, en ocasiones no se aplica y por el contrario, invierte la carga de la prueba y obliga al contribuyente a desvirtuar la responsabilidad determinada por la administración de impuestos.La DIAN – Dirección de Impuestos y Aduanas Nacionales-, cuenta no solo con una serie de recursos físicos, sino que además cuenta con el talento humano, calificado e idóneo para adelantar el proceso tributario; situación contraria, es la que en ocasiones acompaña al contribuyente persona natural, quien   se haya en desigualdad de condiciones frente al ente sancionador.
Environmental Civil Liability under Comparison: Some notes in soft law
Authors: Areal Ludeña Dr. Santiago , Fierro Abella Jorge Alberto
Published: February 2018

La responsabilidad civil medioambiental sirve como complemento de políticas públicas de regulación. Desastres naturales de devastadora magnitud, paralelo al incremento desmesurado de la población mundial, han capturado la atención de políticos y legisladores a escala global. Preocupantes informes de naturaleza tanto oficial como independiente, concluyen en la imperiosa necesidad de establecer un  término para el cambio. Los vacíos dejados por débiles instrumentos internacionales sólo pueden ser subsanados por el estudio comparativo de aquellas normativas que han probado cierto éxito doméstico. Consecuentemente, soluciones europeas y norteamericanas son referenciadas en la actualidad por países en desarrollo. En el presente estudio centraremos nuestra atención en tales desarrollos jurídicos, especialmente en aquellos brindados por el denominado soft law.Después de abordar las especiales características del daño medioambiental, en relación con el daño tradicional, haremos lo propio con los demás elementos configuratorios de la responsabilidad civil. Posteriormente, estudiaremos los elementos característicos de los modelos europeo y norteamericano. Intentaremos dar respuesta a la marcada influencia que históricamente ha ejercido el sistema norteamericano a nivel mundial, así como si ello resulta retrospectivamente justificable. No pasaremos por alto las directivas europeas que desde 1986 hasta 2004 han incorporado importantes avances  respecto de su par Transatlántico. Este será el primero de subsiguientes esfuerzos por incluir un análisis interdisciplinario que involucre tópico tales como la prevención y la autorregulación del daño medioambiental.

Authors: Abdullah Zulfhazli
Published: February 2018

Koordinasi antar simpang secara umum dimaksudkan untuk meningkatkan pelayanan  suatu  jaringan  jalan,  mengurangi  waktu  tunda  dan  waktu  berhenti  kendaraan. Setelah melakukan antrian waktu merah pada salah satu persimpangan, kendaraan diharapkan akan memperoleh waktu hijau pada persimpangan berikutnya. Sistem koordinasi demikian belum diterapkan di  Jalan  Merdeka Kota  Lhokseumawe. Sebagai jalan  utama  pada  pada lintasan tersebut ada dua persimpangan bersinyal yaitu, Simpang Empat dan Simpang BPD. Akibat belum adanya koordinasi antar persimpangan tersebut, sering kendaraan yang baru lolos dari Simpang Empat harus berhenti dan menunggu fase hijau lagi pada Simpang BPD dan begitu juga arah sebaliknya. Sehingga antrian, waktu tundaan dan waktu berhenti yang panjang terutama pada jam puncak tidak dapat dihindari. Metode yang digunakan pada penelitian ini yaitu Metode Manual Kapasitas Jalan Indonesia (MKJI 1997), sementara untuk koordinasi lampu antar simpang menggunakan bantuan perangkat lunak Transyt 14 berpedoman pada metode Transport and Road Research Laboratory (TRRL) Inggris. Transyt 14 digunakan untuk mengevaluasi kinerja persimpangan pada kondisi eksisting serta membuat beberapa alternatif koordinasi dengan performance index (PI) sebagai kriteria utama. Hasil penelitian untuk alternatif terbaik dibandingkan kondisi eksisting diperoleh waktu siklus 100 detik, degree of saturation turun 17,07%, antrian berkurang 14,15%, waktu tunda berkurang 57,38%, jumlah henti turun 20,57%, dan tingkat pelayanan dapat ditingkatkan dari C menjadi B.

As one of the fastest growing tourist destinations, the number of tourist arrivals in Banyuwangi Regency shows a significant growth where in the range of 2010 - 2015 there is an increase of domestic tourists by 161% and abroad by 210%. The increase in tourist numbers is not a trouble-free process, especially with regard to visitor preferences that change over time. Tourist information and a variety of tourist interests often make tourists confused in determining the choice of any destination to visit. While Banyuwangi tourism information that is available in printed form or that can be accessed online still requires tourists to sort and choose their own in accordance with the interests and preferences so that tourists need any suggestions or recommendations. In the field of tourism, this recommendation may include objects to be visited, existing tourist events, travel schedules, travel routes, availability of infrastructure and so forth. The recommendation system proposed in this research uses a combination of (hybrid) case-based reasoning and location-based methods. The system is built in the form of android based mobile applications. Input from users to the system of travelers preferences include tourist types, tariff categories, modes of transportation, and tourism activities. These preferences together with user location based on GPS coordinates are further compared to the tourist object attributes stored on the system using the nearest neighbor similarity method. The output of the system in the form of recommendation of tourism object that has the highest similarity to the user preference. The results of this study are expected to assist tourists in choosing tourism objects in Banyuwangi according to their preferences or demand criteria.

Authors: Hidayati Tuti
Published: February 2018

Indonesian ELT is complex for numerous reasons, and the level of students' outcome has been regarded unsatisfactory by a number of researchers and academics. This paper considers ICT as one of possible alternatives to deal with the complexity of Indonesian ELT and to improve its outcomes. It widely explores ICT integration in English LTL, especially on how ICT has been used in this field. It further investigates the benefits and challenges of integrating ICT in LTL. The paper argues that the integration of ICT is promising for changing and improving the effectiveness of the current Indonesian ELT condition when it is carried out in line with the effective LTL principles. The integration of ICT will enable teachers to vary teaching and learning activities, to gradually change the teaching style to be more student-centred, to train students to have more active role in learning, and to access a huge range of authentic learning materials. The paper also acknowledges the contraints that will emerge in an effort of integrating ICT in Indonesian English LTL. Hence, some recommedations for action are proposed at the end.

Published: February 2018

The World Health Organization’s (WHO) global initiative for the elimination of avoidable blindness by the year 2020 (Thylefors et al., 1995) has prioritized the control of childhood blindness. Currently cataract remains one of the most important causes of treatable blindness in children (Giles et al., 2016).In Nepal, as in other developing countries, cataract is believed to be a leading cause of blindness in children. According to The Nepal Blindness Survey from 1978 to 1980, congenital cataract accounted for 16.3% of blindness detected in children under the age of 15 years (Brilliant et al., 1985). Epidemiology of Blindness in Nepal 2012 survey has suggested that the prevalence of childhood blindness has reduced from 0.68% in 1981 to 0.4% in 2011 (Sapkota, 2012).
Incidence of primary peripheral posterior capsular opacification after cataract surgery and posterior capsular opacification in the patients implanted with foldable intraocular lenses
Authors: Joshi Rajesh Subhash
Published: February 2018

Introduction: Preexisting posterior capsular opacification is commonly seen in the developing world due to late presentation of patients for cataract surgery. Patients are implanted with either hydrophilic or hydrophobic IOL. Effect of these IOLs on pre-existing posterior capsular opacification has not yet been reported.Aim: To determine the incidence of peripheral preexisting posterior capsular opacity (PPPCO) in patients undergoing cataract surgery and the rate of posterior capsular opacification (PCO) following implantation of hydrophilic and hydrophobic intraocular lens (IOLs).Study design: Prospective, observational case study Setting: Tertiary eye care center in central India. Methodology: 1400 consecutive patients undergoing phacoemulsification of senile cataract between July 2009 and June 2010 discovered to have PPPCO were included in the analysis. Patients were either implanted with hydrophilic (n= 40) or hydrophobic IOL (n=40). Images of the posterior capsule immediately and 3-years postoperatively were compared. Patients were followed up for development of PCO, visual outcome at 3 years and neodymium: YAG laser posterior capsulotomy (NYLPC) rate.Results: Eighty patients were found to have PPPCO (incidence of 5.7%). 47.5% of PPPCOs were from mature senile cataracts (n = 38), 36.2% were from posterior subcapsular cataracts (n = 29) and 16.2% were from posterior polar cataracts (n = 13). NYLPC was performed in 9 patients receiving hydrophilic (22.5%) and 3 patients receiving hydrophobic IOLs (7.5%; p = 0.12). Average time to NYLPC was 18 months in the hydrophilic and 30 months in the hydrophobic group (p = 0.002). Visual outcome was satisfactory at 3-years of follow-up.Conclusion: PPPCO is a frequent occurrence in mature cataract and there is a higher incidence of PCO in PPPCO patients implanted with hydrophilic IOL than with hydrophobic IOL. Therefore, hydrophobic IOL should be considered for patients discovered to have PPPCO during cataract removal.

Published: February 2018

Introduction: The conjunctiva is a thin and flexible mucus membrane that provides a protective barrier for the eye. Very few histopathologic studies have been conducted on biopsies from conjunctival lesions (CL) in central India.Objective: To study the spectrum of CL and define those lesions that need attention with regard to need of biopsy in order to prevent grave sequelae and ocular morbidity.Results: Degenerative conditions such as pterygium followed by pinguicula were the commonest lesions seen in conjunctiva. Out of 129 subjects, youngest in the series was 3 years old while oldest patient was 72 years of age. Commonest age interval for involvement was 35 to 50 years. In children below 8 years, cystic lesions (infective or inclusion), limbal dermoid and choristoma were seen. Vascular lesions were noticed by patients for the first time between mid-teens to 25 years age. Premalignant lesions were dysplasia, actinic keratosis and PAM with or without XP. Malignant lesions in this series were squamous cell carcinoma, basal cell carcinoma and sebaceous carcinoma; which were observed in the age interval 25 to 75 years. In none of the malignant conditions there was deeper penetration into the globe or orbit. Though diagnosed within two weeks duration (by incisional biopsy) from appearance of nodule, unfavourable outcome was seen only in one malignant CL; a case having sebaceous carcinoma. In all pediatric cases outcome was good, except in child having choristoma, where amblyopia ensued before a diagnosis was made. Response to sclerotherapy was excellent as all the epibulbar vascular malformations regressed. All degenerative lesions regressed except one recurrence in a recurred pterygium. Case diagnosed as large B cell lymphoma recurred after one year. Dysplastic changes were seen to occur at limbus on followup in one XP, but in all cases of naevi, neither cellular atypia was seen nor melanoma developed.Conclusion: An overview of various CL disclosed that clinician has to differentiate benign from premalignant and malignant lesions. Early diagnosis, proper histological study and patient education, all are equally important for achieving good outcome.

Introduction: Ocular decompression retinopathy (ODR) is a relatively rare entity with variable prognosis depending on extent and pre-existing condition. This article describes profile of two cases with a brief review of the condition.Case report: Case 1 highlights extensive choroidal detachment with subhyaloid haemorrhage and multiple intra-retinal hemorrhages in the posterior pole seen on first post-operative day in a 6 year old child with congenital glaucoma who underwent Trab & Trab. Case 2 describes multiple intraretinal hemorrhages seen at posterior pole on second post-operative day in a 24 year old pregnant lady with post traumatic cataract and secondary glaucoma who underwent cataract extraction with Cionni ring. Both patients had complete resolution of the haemorrhages with topical steroids.Conclusion: Ocular decompression retinopathy is mostly seen after operations on cases with advanced glaucoma and those with vulnerable blood flow fluidics. Adequate precautions to prevent this entity should be adopted during surgery and management of the manifest entity is conservative with good prognosis.
Spontaneous formation and closure of full thickness macular hole in a vitrecto-mised eye : a case report
Authors: Gurung Rajya Laxmi
Published: February 2018

The exact pathogenesis of macular hole (MH) is controversial with most of the cases being idiopathic. Trauma is an important cause of secondary MH formation. MH post Pars Plana Vitrectomy (PPV) is an even rare entity with only a handful of cases reported so far ( Kumagai et al, 2008; Smiddy W.E, 1993; Kimura et al, 2005). An even rarer event is spontaneous closure of post PPV full thickness macular hole (FTMH), though spontaneous closure of traumatic macular hole (TMH) has been reported before. Herein, we report a 26 year old male patient who developed FTMH post PPV that closed spontaneously.

Published: February 2018

Management and disposal of waste polyethylene terephthalate (PET) bottles is an ever-growing challenge. The present study investigated the effect of incorporation of shredded waste PET bottles on properties of asphalt mixes in terms of: (i) process of PET addition, (ii) PET content, and (iii) PET size. Experimental design included three variables: two processes (dry process, and modified dry process), three PET contents (2.5%, 5.0%, and 7.5% by weight of binder), and two PET sizes (2.36–1.18 mm, and 0.30–0.15 mm). Volumetric properties, Marshall parameters, and moisture susceptibility characteristics of PET modified mixes were evaluated and compared with control mix (without PET). Analysis of variance (ANOVA) was performed to evaluate main and interaction effects of the variables. Results indicated that all the three variables had significant influence on the measured properties. Further, mixes prepared using modified dry process outperformed other mixes and showed highest resistance towards moisture induced damage.
Verification of the Ramberg-Osgood Material Model in Midas GTS NX with the Modeling of Torsional Simple Shear Tests
Authors: Szilvagyi Zsolt , Ray Richard P.
Published: February 2018

This study focuses on the back analysis of a geotechnical laboratory test with nonlinear finite element modeling using the Ramberg-Osgood material model. This model has been used by several authors recently for nonlinear ground response analysis and it has been implemented by Midas into their commercial finite element code Midas GTS NX 2014. The verification of the model for 1D nonlinear site response analysis can be found in the documentation of the software package. In this study, Torsional Simple Shear tests were modeled and a comprehensive study was performed to provide verification of the material model for static torsional loading and axisymmetric conditions.

Authors: Mustafaraj Enea , Yardim Yavuz
Published: February 2018

In this paper, it is presented the experimental results of a campaign on diagonal compression tests, as of ASTM E519-02, to assess and compare the in-plane behavior of standard size of 1200 × 1200 × 250 mm, for three unreinforced and three reinforced wall panels by glass fiber reinforced polymer (GFRP) embedded in an inorganic matrix.From the diagonal compression test results, were determined some of the main mechanical parameters such as: shear strength, modulus of rigidity and ductility, before and after application of the reinforcement.The experimental results showed that the GFRP reinforced panels exhibited a significant increase of 127% in shear resistance, 1100% in ductility and 650% in modulus of rigidity when compared to unreinforced panels.It was concluded that this technique provided satisfactory results and can be considered a suitable method for repair of masonry structures.

Authors: Mazaheri Hamid , Rahami Hossein , Kheyroddin Ali
Published: February 2018

In this paper, a simple method for defining the effects of cracks on elastic behavior of beam is presented. The cracked sections were modelled as rotational springs and the problem was solved using the finite element method. The global stiffness matrix of a beam with multiply cracked section was then assembled. For calculation of rotational spring stiffness equivalent to uncracked and cracked sections, finite element models and experimental test were used.The natural frequencies and mode shape of beams with multiple single-edge cracks were obtained and a new simple formula was proposed. Published numerical examples for cracked beams were used for validation.
Optimal Design of Jacket Supporting Structures for Offshore Wind Turbines Using CBO and ECBO Algorithms
Authors: Kaveh Ali , Sabeti Sepehr
Published: February 2018

Structural optimization of offshore wind turbines is a tedious task due to the complexity of the problem. However, in this article, this problem is tackled using two meta-heuristic algorithms - Colliding Bodies Optimization (CBO) and its enhanced version (ECBO) - for a jacket supporting structure. The OC4 reference jacket is chosen as a case study to validate the methods utilized in this research. The jacket supporting structure is modeled in MATLAB and its optimal design is performed while both Ultimate Limit State (ULS) and frequency constraints are considered. In the present study, it is presumed that both wind and wave phenomena act in the same horizontal direction. As a result, all resultant forces and moments will act in-plane and the substructure can therefore be modeled in 2D space. Considerable weight reduction is obtained during the optimization process while fulfilling all constraints.
Modeling of Creep Behavior of an Argillaceous Rock by Numerical Homogenization Method
Authors: Dahhaoui Hachimi , Belayachi Naïma , Zadjaoui Abdeldjalil
Published: February 2018

This paper is devoted to modeling the creep behavior of argillaceous rock and a comparison with experimental and numerical results from literature. The proposed time dependent modeling is based on a numerical homogenization method, matrix-inclusion material microstructure and a creep micromechanical model. The nonlinear viscosity of the argillaceous matrix is described by the creep model “Modified Time Hardening”, while classical linear elasticity is applied for the calcite and quartz inclusions. The simulation accuracy was analyzed under single and multistage creep test. A satisfactory agreement between the simulation and the experimental results are obtained by assuming the main mineral phases of the Callovo-Oxfordian argillite.  It was found that better agreements could be obtained when the multi-scale modeling is performed on sample with a given mineralogical composition and much more precisely volume fraction. The results show how numerical homogenization method is capable of effectively modelling macroscopic creep deformation.
Nondestructive Testing of Stabilized Soils and Soft Rocks via Needle Penetration
Authors: Dipova Nihat
Published: February 2018

Assessing the strength of hard soils and soft rocks is a pressing issue in geotechnical investigations, since high quality core samples recommended by testing standards for strength determinations cannot always be achieved. As a solution, a light-weight, non-destructive testing device, Needle Penetrometer (NP), was developed in Japan. It is not well known and standardized in other parts of the world. No sample preparation is required, and it is applicable both in the field and laboratory with minimum surface conditioning. This study aims to provide some new contributions to previous works on the NP test, including new rock types and stabilized soils. For these purposes, unconfined strength (UCS) and needle penetration resistance (NPR) values were determined for compacted clays, lime and cement stabilized clays, micritic tufa, microdetrital tufa and pumice. A database consisting of a total of 108 UCS–NPR data pairs was established. Regression analyses reveal that, there is a significant relationship between UCS and NPR. It is concluded that the NP tests can be applied to stabilized soils and soft rocks with UCS of up to 30 MPa to predict the UCS from NPR.
