Desarrollo local, posconflicto y ciudades sostenibles
Authors: Muñoz Angulo Luis Guillermo 
Published: December 2016

Se realizó una descripción analítica sobre los concepto de desarrollo, desarrollo local y ciudades sostenibles, dentro del marco de un posible posconflicto, a partir de la literatura existente sobre estos temas, además de efectuar un paralelo para identificar si la ciudad de Neiva, en el Departamento del Huila, Colombia, cuenta con las bases suficientes para identificar la presencia de un verdadero desarrollo local o la evidencia de programas o estrategias público-privadas que la conduzcan a convertirse en un futuro inmediato o a corto plazo en ciudad sostenible. Revisados los últimos tres (3) Planes de Desarrollo Municipal del Municipio de Neiva, en especial, el actual Plan de Desarrollo 2012-2015: “Unidos para mejorar”; se advierten acciones aisladas que se consideran débiles frente a un programa fuerte sobre desarrollo local o metodología de ciudad emergente o sostenible por no haberse adoptado la iniciativa de Ciudades Emergentes o Sostenibles que apoya el Banco Interamericano de Desarrollo-BID en alianza con la Financiera de Desarrollo Territorial-FINDETER, instrumentos que ya han iniciado ciudades como Barranquilla, Bucaramanga, Manizales, Pereira, Montería y Pasto, desde el año 2010, entre otras ciudades latinoamericanas.
El trabajo infantil rural: un puente para la construcción de saberes en la escuela rural
Authors: García Mendivelso Viviana Andrea 
Published: December 2016

En este artículo se presentan las reflexiones pedagógicas después de dos años de práctica docente en la Escuela Rural La Argentina, con estudiantes del ciclo 3. Con el ejercicio de indagación-reflexión se pretendió rastrear el papel del trabajo infantil rural en los procesos de enseñanza/aprendizaje en la escuela rural. La hipótesis del trabajo se centró en la pregunta: ¿Cómo dignificar/resignificar la mirada del trabajo infantil rural a través de una propuesta pedagógica interdisciplinar para potenciar el aprendizaje en los niños y niñas de la Escuela Rural La Argentina? Posteriormente se realizó una revisión bibliográfica que aborda el trabajo infantil como una actividadpositiva en el desarrollo de la infancia. Así, se sustentó lo encontrado en la práctica pedagógica: los menores desarrollan ciertas actividades en el área rural en las que construyen diversos saberes; estos fueron retomados para implementar una propuesta pedagógica alternativa que rescatara dichos saberes para ponerlos en diálogo con la escuela.

An examining the relationship between the trust in supervisors and interactional justice among the tourism employees
Authors: Çelik Pınar , Gök Cengiz 
Published: December 2016

In recent years there has been a great increase in the number of researches dealing with trust in different disciplines. The reason of this increase is as modern societies become more and more complicated and disciplines pay more attention to reasons of human behaviour. One of the sectors that human behaviour has a vital and important role is tourism industry. Knowing the level of trust that employees have for their supervisors in tourism industry will help the enterprises to increase the level of their service quality and their effort to survive for along time in this competitive environment. When employees trust their supervisors, their added value to the enterprise will increase and they will contribute more to enterprise to reach its pre-set goals. In this study it is aimed to determine the level of trust that tourism employees have for their supervisors and possible results of trust level for the enterprise. In regression test made between trust in supervisor and interactional justice perception, trust in supervisor can be explained by interactional justice with 63%.

Published: December 2016

The purpose of this study was to determine the levels of mathematics and mathematics education students’ views about mathematical proof and find out whether there was a significant difference among students’ views according to their departments or not. The study was conducted with senior students (n=275) studying in final year at the department of Primary Mathematics Teacher Training (n=98), Secondary Mathematics Teacher Training (n=87) and Mathematics (n=90) at a state university at the beginning of the spring semester of 2014-2015 academic terms in East Anatolia Region of Turkey. Quantitative research approach was adopted in this study. The model of the study was comparative research which was one of the model in the nonexperimental research designs. The data were collected with Conception Scale for Mathematical Proof developed by Doruk and Güler (2014). Results of the study showed that secondary mathematics teacher training students had more negative overall views, more negative views regarding benefits obtained from mathematical proof in mathematical sense, and less self-confidence, and more negative views about meaning assigned to proof than other students. Moreover, it was revealed that mathematics students’ views regarding necessity of proof in mathematics and mathematics education were more positive than other students.

Anal Carcinoma: A Series of Cases with a Literature Review
Authors: Stošić Momčilo , Stojanović Igor , Mihajlović Svetlana , Zdravković Kosta 
Published: December 2016

Abstract
The aim of this study was to analyze the cases of five patients with squamous cell carcinoma (SCC) and to draw attention to the dilemma in the treatment of incontinence on admission of these patients and to present, through a literature review, locations of the surgical treatment.
The anal carcinoma is a rare disease which involves different histopathological (HP) types of cancer. They account for about 2.5% of all digestive cancers. The treatment of the disease is multimodal. There are dilemmas about screening of precancerous lesions and treatment of diagnosed incontinence. There is a high similarity between HPV infection and SCC. Our methods and results were compared with the data from the literature.
In the period of three years (from 2013 to 2015), five cases of the anal carcinoma were diagnosed and treated in the regional hospital. In all of our cases, the disease was histopathologically confirmed as SCC of the anal and perianal areas. It excluded the cases of anal adenocarcinoma (AAC).
Nearly half of the patients (40%) were incontinent and the rectum excision was one of the possible solutions. Distinction in histopathological structure created the confusion in the treatment of these patients. The dilemma we had was whether to do an amputation of the rectum in patients with incontinence before the standardized Chemoradiation therapy (CRT). The review of the literature sums up certain conclusions.
The diagnosis of SCC includes the perianal "ulcer" that does not heal, as well as atypical anoperianal growths. Surgical treatment of SCC is indicated when the diameter of lesion is small (2 cm), or the disease is persistent or recurrent. In the case of anal incontinence because of the tumor changes, the abdominoperineal resection of the rectum (APR) is an alternative to performing bipolar colostomy and CRT. The review of the literature using MEDLINE/PubMed databases did not find the case with restoring anal continence after this treatment. Testing a larger number of patients with incontinence on admission would provide a more clear answer to the question of the treatment of these patients.
Testing the associations between different aspects of seafarers’ employment contract and on-board internet access and their job and life satisfaction and health
Authors: Slišković Ana , Penezić Zvjezdan 
Published: December 2016

Abstract
The aim of this study was to test for associations between different aspects of contract and on-board internet access and seafarers’ satisfaction and health. Altogether 298 Croatian seafarers, all officers, employed on cargo ships, with a minimum work experience of two years with their current shipping company, participated in an online survey. The questionnaire included sociodemographic items, questions relating to their employment contract and internet access, and measures of job satisfaction, life satisfaction, mental health, and gastrointestinal and cardiovascular symptoms. Their job- and lifesatisfaction levels were higher for shorter duration on board, favourable ratio of work to non-work days, and compliance with the employment contract regarding the changes to work and non-work days. Mental health differed likewise but only in relation to two aspects of the contract: on-board duration and compliance with the contract. The level of gastrointestinal symptoms was lower in cases of shorter on-board duration and compliance with the contract, and in seafarers who have free, unlimited internet access on board. Lower level of cardiovascular symptoms was found in seafarers with free, unlimited internet access on board. Our findings suggest that in promoting satisfaction and health in seafaring, attention should be given to reducing on-board duration, compliance with the contract, and internet accessibility on board.

Published: December 2016

Abstract
Investigations of natural radioactivity in water, air, and soil are conducted frequently and routinely. Exposure to high concentrations of natural radioactive radon gas can cause irradiation of respiratory organs, which can lead to lung cancer. This paper presents measurements of radon activity concentrations in dug wells and natural springs of the Tuzla area (Bosnia and Herzegovina), which ranged from 214 to 3702 mBq L-1. Our results have shown that the radon activity concentration did not exceed the EU reference level for radon in drinking water (100 Bq L-1).
