Published: April 2020

Um dos traços fundamentais que definem a agricultura familiar é a centralidade do trabalho doméstico nos processos produtivos. Todavia, claras são as evidências de que as mutações demográficas, sobretudo o processo de envelhecimento da força de trabalho rural, trazem consigo uma série de desdobramentos sobre o modo como operam hoje tais explorações, ameaçando sua continuidade. Esse fenômeno impacta fortemente os estados meridionais do Brasil, especialmente o Rio Grande do Sul. É no extremo sul gaúcho que a cultura do pêssego foi implantada no século XIX por imigrantes europeus, a qual é majoritariamente conduzida em explorações familiares. A produção tanto pode ser destinada para fabricação de compotas como para o consumo in natura. Trata-se de cultivo que ocupa um grande número de trabalhadores externos (safristas) nas operações de poda, raleio e especialmente colheita. Não obstante, nos últimos anos há um flagrante descenso na disponibilidade dessa mão de obra rural por conta das transformações gerais que incidem sobre o campo. O objetivo central desse artigo é analisar as relações de trabalho tecidas entre produtores familiares e os trabalhadores empregados durante o ciclo do pêssego. A investigação envolveu a realização de vinte entrevistas em profundidade e de outras técnicas de pesquisa. O estudo trouxe à luz a invisibilidade das relações tecidas entre produtores e a força de trabalho empregada durante o ciclo produtivo, as regras que regem o seu funcionamento, as formas de contratação, condições oferecidas aos trabalhadores e a importância da agricultura familiar como empregadora e geradora de renda rural.

En este trabajo se presentan los datos del contenido polínico de la atmósfera de la ciudad de Palencia, registrado a lo largo de tres años consecutivos de muestreo (1990-92), empleándose un captador volumétrico de filtracción activa, tipo CAP2. Durante este período se identificaron 88 tipos polínicos diferentes, de los cuales, 27 tuvieron porcentajes de representación superior al 0,15% respecto al polen total que anualmente se recogió, estos tipos conforman el denominado espectro polínico principal de esta estación de muestreo. El polen procedente de especies herbáceas (Poaceae, Chenopodiaceae, Plantago, Urtica, etc.) con un 53,79% fue el predominante, el polen arbóreo (Quercus, Populus, Cupressaceae, etc.) supone un 42,11%, y el polen procedente de especies arbustivas (Ericaceae, Sambuctts, etc.) sólo representó el 4,10%. El período de máxima emisión polínica se concentra en los meses de mayo y junio, debido a las aportaciones de polen procedente de Poaceae y Quercus, que en conjunto suman el 47,25% del polen recogido durante el trienio muestreado. El polen de origen herbáceo aparece durante todo el año, y sus máximas concentraciones se registran en primavera, coincidiendo con los máximos niveles de polen de origen arbóreo en la atmosfera.

Many investigations related to the analytical solutions of the nonlinear sub-diffusion equation exist. In this paper, we investigate the conditions under which the analytical and the approximate solutions of the nonlinear sub-diffusion equation and the nonlinear sub-advection dispersion equation exist. In other words, the problems of existence and uniqueness of the solutions the fractional diffusion equations have been addressed. We use the Banach fixed Theorem. After proving the existence and uniqueness, we propose the analytical and the approximate solutions of the nonlinear sub-diffusion, and the nonlinear sub-advection dispersion equations. We analyze the impact of the sub-diffusion coefficient, the advection coefficient and the dispersion coefficient in the diffusion processes. The homotopy perturbation Laplace transform method has been used in this paper. Some numerical examples are provided to illustrate the main results of the article.

Authors: Sari Ramazan
Published: April 2020

In this paper different curvature tensors on Lorentzian Kenmotsu manifod are studied. We investigate constant ϕ–holomorphic sectional curvature and ℒ-sectional curvature of Lorentzian Kenmotsu manifolds, obtaining conditions for them to be constant of Lorentzian Kenmotsu manifolds in such condition. We calculate the Ricci tensor and scalar curvature for all the cases. Moreover we investigate some properties of semi invariant submanifolds of a Lorentzian Kenmotsu space form. We show that if a semi-invariant submanifold of a Lorentzian Kenmotsu space form M is totally geodesic, then M is an η−Einstein manifold. We consider sectional curvature of semi invariant product of a Lorentzian Kenmotsu manifolds.

In 2002, through the national standardization agency, the Indonesian government issued SNI 03-1726-2002 on Earthquake Resilience Planning Standard for Building Structure to anticipate the effects of earthquake on building. However, after the standard has been issued there have been several other major earthquakes that rendered it necessary to revise the existing standards. Therefore, in 2012 the government issued SNI 03-1726-2012 on Procedures for Earthquake Resistance Planning for Building and Non Building Structures. When viewed from both these standards, it can be seen that Aceh province is one of the provinces with high earthquake intensity so it is necessary to do a research to observe the effect of changes of both standards to the ratio of column capacity and minimum reinforcement requirements for buildings constructed in Aceh province. Based on the results of the research, the average column capacity ratio against the load in SNI 03-1726-2012 has increased by 45.02% and the average minimum reinforcement requirement available is only 54.5%. The increase is due to an increase in primacy factor from 1.0 to 1.5, causing increased structural load. In addition, there was an increase in the combined burden in the form of 30% additional redundant factors as well as the addition of earthquake load due to an increase in rock bed acceleration factors in some regencies. Thus it can be concluded that the building under review has not fulfilled the requirements of SNI 03-1726-2012 and is recommended for planning by adding a shear wall to reduce the structural load.

Published: April 2020

In the design of high and low-rise buildings, structural systems should consider the requirements of strength, stifness, and stability. The addition of bracing affects the stiffness of the structure of the building. In SNI 03-1729-2002 there is an Effective Length Method (ELM) method which only recommends first-order analysis with amplification factor. However, currently there is a new structural design regulation that is SNI 1729: 2015 which refers to the American Institute of Steel Contruction (AISC 2010) where the steel structure stability planning has taken into account the second-order effect directly. This study aims to compare the application of Direct Analysis Method (DAM) and Effective Length Method (ELM) on 2D simple structure, where the comparison of both methods is focused on stress ratio value, which aims to determine more effective and efficient method in designing of braced steel frame structure. The difference values of stress ratio obtained in this study varies from 0.1 to 8.9%, where the value of DAM stress ratio is smaller than ELM. Comparison between the two methods shows that DAM is a more effective method and results in higher profile capacity than ELM.

The construction of medium and infrastructure of transportation has to be followed by the population growth. The trend to divide a regency / city into new separate one was perceived from the theorem of public welfare. This perception generates a big problem throughout Indonesia. Central Bureau of Statistics (2015) stated that the most populous city after Banda Aceh and Lhokseumawe is Langsa. Population of the city increased after the expansion in Langsa in term of motor vehicle. The congestion emerges at the peak hours, between 7.30 to 8.30 AM, 12.30 to 1.30 PM and 3.30 to 4.30 PM IWST. To anticipate this problem, the government of Langsa city in 2015 constructed a new road in the northern area, when the eastern area is not as effective since the width of the road is varied and it needs substantial cost for the construction. On the other hand, the existing road (national road) aquire longer travel time to access the office, education and shopping centre. Therefore, author was interested to observe these 3 (three) road, which generate a result stating that the time required to travel in the existing road is 1.15 hours and 0.03 hours in the alternative road for each one-way travel. The aimof this research is to analyze the benefit for road users by applying consumer surplus method and the public perception in terms of economy based on the Vehicle Operating Cost (VOC), saving of travel time and economic feasibility study based on Benefit Cost Ratio (BCR), Net Persen Value (NPV), Economy Internal Rate Return (EIRR) and sensitivity analysis.

The concept and scope of restorative justice for juveniles According to the Islamic and Jordanian Legislations
Authors: Al-Saleh Ebtisam , Al-Soury Kefah , Al-Daher Hanan
Published: April 2020

The adoption of the restorative justice approach is more appropriate for the children in conflict with the law and more sensitive to achieving their best interests and rehabilitating them to facilitate their reintegration into society again  ( socializing ),  and to play a constructive role in the society,  and not to return to violating the law again,  unlike the traditional policy in the criminal justice,  which did not give the sufficient weight to the personal and objective circumstances of the child ,  and it focused on the punishment and criminalization for every wrongful act without looking at restorative  alternatives to the convicted child . The restorative justice, therefore, is an alternative approach to the ordinary criminal procedure in certain cases. The judicial system is not the only procedure that must address the phenomenon of children in conflict with the law in all cases.   In certain cases, it is better to conduct a dialogue and mediation between the perpetrators and the victims, with the aim of reaching to repair the harm and to rehabilitate the perpetrators (children) according to the measures outside the judicial system.  This is what Islamic Shari’a called fourteen centuries ago.  The Shari’a (Islamic Law) defined the criminal reconciliation and approved it as one of the most serious types of crimes against the self by the adult, as it has indicated.  According to the Shari’a, the juvenile, whether he is cognizant or not of, is not criminally responsible for the violations he commits nor a case will be filed against him and no penal action will be taken against him.

Published: April 2020

A methodological approach for conducting a technological foresight at the corporate level has been proposed. A corporate foresight based on general methodological approaches used in world practice should take into account a number of additional factors imposed by the specifics of the industry and organization in order to obtain a list of priority technologies and technological directions relevant to the company’s activities. Methodological approach is based on the concept “Markets-Trends-Technologies”. Global markets research allows us to determine key problems and trends of society evolution in economic, social, political and other arears. The transition to the corporate level is carried out by identifying trends in the company’s industry. The methodology have described in detail the methods of attracting experts to assess the power of mutual influence of trends and technologies. The results of the assessment can be used for subsequent technological mapping in scientific and technical forecasting and strategic planning.
