Palu city is one of the cities with unstable changes of natural conditions. The natural conditions such as the frequency of rainy day, temperature and humidity which are always changeable bring bad impacts and will cause of diseases especially dengue hemorrhagic fever (DBD). Therefore, it needs an action to recognise whether or not the natural condition factor influences the spread of DBD and determines what factors of the natural condition can influence the spread of DBD. This research applied quantile regression in the case of DBD in Palu city. Quantile regression is an analysis technique regarding to the functional relationship between one dependent variable with one or more independent variables which can provide accurate and stable results even though there will be outliers. Based on the result of the research, it is obtained that the natural condition factor affected the spread of DBD. This is because from 3 natural conditions only 11 significant or influential quantiles on the tested data, the quantiles are 0,30; 0,35; 0,40; 0,45; 0,50; 0,55; 0,60; 0,65; 0,70; 0,75 and 0,80. Meanwhile the most influential factor of natural conditions in spreading DBD is the frequency of rainy day because it has positive which means that 1 progress of percentage will increase the quantity of DBD case.

Published: January 2020

Abstract

Background
The accuracy of any radiation therapy delivery is limited by target organ translocation and distortion. Bladder filling is one of the recognised factors affecting prostate translocation and distortion. The purpose of our study was to evaluate the effect of bladder volume on prostate translocation and distortion by using detailed three-dimensional prostate delineation on MRI.

Patients and methods
Fifteen healthy male volunteers were recruited in this prospective, institutional review board-approved study. Each volunteer underwent 4 different drinking preparations prior to imaging, with MR images acquired pre- and post-void. MR images were co-registered by using bony landmarks and three-dimensional contouring was performed in order to assess the degree of prostate translocation and distortion. According to changes in bladder or rectum distention, subdivisions were made into bladder and rectal groups. Studies with concomitant change in both bladder and rectal volume were excluded.

Results
Forty studies were included in the bladder volume study group and 8 in the rectal volume study group. The differences in rectal volumes yielded higher levels of translocation (p < 0.01) and distortion (p = 0.02) than differences in bladder volume. Moderate correlation of prostate translocation with bladder filling was shown (r = 0.64, p < 0.01). There was no important prostate translocation when bladder volume change was < 2-fold (p < 0.01). Moderate correlation of prostate distortion with bladder filling was shown (r = 0.61, p < 0.01).

Conclusions
Bladder volume has a minimal effect on prostate translocation and effect on prostate distortion is negligible. Prostate translocation may be minimalised if there is < 2-fold increase in the bladder volume.

Global warming becomes a pressure in food production sustainability because it affected crop growth and development. The purpose of this study was to obtain information on the effect of high-temperature stress on the growth and development phase of rice and to evaluate the genotype for tolerance to high-temperature stress. Two environment conditions were used in the field and greenhouse of IPB Cikabayan experimental field, IPB University from August 2016 until February 2017. The study used varieties of IPB 4S, IPB 6R, Mekongga, and Situ Patenggang. High-temperature treatment was done by transferring the rice plants to the greenhouse at 50 days after transplanting. Observations were made on the generative phase in two different environmental conditions. The results showed that the total tillers number, filled grain number per panicle, unfilled grain number per panicle, total grain number per panicle, grain filling rate, percentage of filled grain and filled grain weight per plant had different responses among rice genotypes due to high-temperature stress. High-temperature decreased pollen fertility in all genotypes, which classified IPB 4S as a sensitive genotype and Mekongga as a tolerant genotype. This information could be useful for development and improving rice variety to anticipate high-temperature stress.

Published: January 2020

Salt solubility is the abiotic pressure which has the most effect on the loss of plant quantity and quality. Salinity not only makes plants stressful but also presents severe constraints on crop production so an attempt to understand plant adaptation mechanisms is important for expanding agricultural production on saline soils. This study aimed to obtain a mechanism for the adaptation of hybrid and composites maize to NaCl stress through anion and cation absorption patterns. The experiments were carried out at the LLDikti Region X Laboratory from May to August 2016. The experiments were arranged in a factorial complete randomized design with three replications. The first factor was corn varieties, namely: hybrid corn (Pioneer 22 and Bisi 12), and composite corn (Bisma and Sukmaraga). The second factor was level of NaCl, namely: 0.0 mg kg-1 NaCl pH 5.0, and 4,000 mg kg-1 NaCl pH 5.0. Measurement of anions and cations using Spectroquant Thermoreator TR Nova 420. The adaptability of hybrid maize and composites to NaCl stress occurred through the mechanism of anion absorption and cation metabolism. The difference in the percentage of NO3-, NO2-, PO4-, NH4+, and K+ levels between hybrid maize varieties and composites showed a difference in the adaptation ability of maize varieties to salinity stress.

Excessive use of inorganic fertilizers is suspected to be the cause of low productivity and poor bulb storability that reduced their use. Goat manure organic fertilizer (GMOF) can be an alternative in reducing the use of these inorganic fertilizers. The study was conducted in March to June 2019 in the shallot field at Sukorejo Village, Rejoso District, Nganjuk Regency, East Java. The research aims to determine the dose of inorganic fertilizer which can be reduced by adding goat manure to increase the growth and production of shallot bulbs. This experiment used 2 factors, namely manure consisting of 2 levels (0 and 10 tons ha-1) and inorganic fertilizer consisting of 5 levels (0, 25, 50, 75, and 100% inorganic fertilizer reference dose). The treatment was repeated 4 times so that there were 40 experimental plots with a size of 2 m x 4 m, using Super Philip variety. The addition of 10 tons ha-1 of GMOF to shallot cultivation in Nganjuk Regency could reduce the use of inorganic fertilizer to 50%.

Invisibilized creativity: Sociogenesis of an “innovation” process developed by cartoneros for post-consumption waste recycling
Authors: Carenzo Sebastian 
Published: January 2020

Unlike the private companies that runs the waste collection system, the recovery and classification of waste carried out by cartoneros (waste pickers) in Buenos Aires metropolis has not yet been acknowledged as a “public service” (one of the main demands of cartonero organizations). Their work is based on the commercialization of recovered materials for the local and global recycling industry in a market defined by high levels of intermediation and incidence of monopolies in price formation. Consequently, levels of profitability attained in this first link of the chain are extremely meager, hence the importance of achieve value-adding issues becomes key for strengthen the economies of their organizations. Moreover, some public policy actions were oriented to address this goal by a so called process of "technification" of their working process. However, the results obtained so far, were not encouraging at all. Over more than a decade of the emergence of the cartonero phenomenon in Argentina, the technological features of their job have not shown significant changes. Most of them still focus on collecting and sorting as main activities, using very analyzes an “innovation” process developed by members of a cartonero cooperative in the Greater Buenos Aires. The project involves the recycling of industrial cellulose waste for manufacturing bricks and plates for housing construction. The core of my argument can be synthesized in the following question: what happens when an “innovation” process does not come from the contribution of specialized “technicians”, but responds to an experimental practice developed by the cartoneros themselves?.
This shift at the level of the socially legitimate locus to produce “innovation” is analytically revealing for examining the contradictory dynamics in the construction of social relations deployed in this experience, focusing mainly on the tensions present in the institutionalization of the ongoing creative process.rudimentary tools and machines and obtaining a small profit if we consider the hard work they make on a daily basis.

Retooling Engineering for Social Justice: The use of explicit models for analytical thinking, critical reflection, and peer-review in Swedish engineering education
Authors: Larsen Katarina , Gärdebo Johan 
Published: January 2020

This paper engages with social justice in engineering education based on pedagogical tools aimed at improving analytical reading, writing and critical reflection in course activities. The authors conceptualizes analytical thinking, critical reflection, and web-based peer review as tools for transformation of student learning, and apply these tools as instructions to engineering students studying city planning in Stockholm, Sweden. Students were asked to use the tools to critically analyze the role of national identities, social vis-à-vis technological engineering, and what politics have shaped Swedish society. In studying these aspects of city planning, the authors argue for a shift in attention toward the practices of engineers’ work around issues of social justice, an argument reinforced by the results of textual analysis of student essay reflections on social justice in city planning. The results are a wide range of themes of critical reflection made by students arising from course activities. These included balancing social and environmental justice, like suburban segregation, planning ideals and, in some cases, challenges for the planning profession. We argue that these are valuable lessons for engineers, which can be achieved by combining practical experiences of planning practices with tools for advancing critical and analytical skills of engineering students. By analyzing engineering students’ views on solutions and challenges of addressing social justice in practice, we can improve our understanding of the engineering skills required to work with social justice. In this way, the study complements discussion and critiques of the relationships between society and engineering outlined in the rhetoric of engineering grand challenges, and contributes by discussing new roles for engineers in facing day-to-day challenges working with social justice.
A Theoretical Basis for Addressing Culture in Undergraduate Mining Education
Authors: Johnson Anne 
Published: January 2020

Communicating across cultural difference is a challenge for the mining industry as its attempts to gain social licence to operate in the traditional territories of Indigenous peoples. Industry organizations affirm their intention to respect communities and to develop mutually beneficial relationships, but because an understanding of culture is not a part of the mining engineer’s expertise, this goal cannot be fully realized. The undergraduate mining curriculum could address this deficiency through a critical study of culture and development of the dialogic communication skills associated with intercultural competence.
Arguing that the epistemology of engineering is problematic in the cultural encounter, this paper examines, the ways in which disciplinary culture is transmitted and mechanisms for cultural change. With the objective of producing interculturally competent mining engineers, it outlines application of critical theories to deconstruct the hegemony of engineering knowledge and of communication theories to support a culturally-competent and effective approach to knowledges.
