Detecting Depression from Tweets with Neural Language Processing
Authors: Wen Sijia 
Published: February 2021

Abstract
As social media becomes a major part of everyday life, analyzing language on social media is becoming a potentially fruitful approach to discover depression patients. At a time when depression is starting to be taken seriously, sentiment analysis through social media should be studied further so that people can be treated in the early stages of depression. With the intention to detect depression behavior through studying language on social media, we built a classification model for depression detection by training on a Tweets dataset from Shen et al 2017. After optimizing hyper-parameters including learning rate and embedding dimension, the language classification model achieves the test accuracy of 98.94% and an F1 score of 99.04% which is higher than the best performance of 85% F1-measure achieved by Shen’s work. These results show that the method is effective and can be used in a wider range of unlabeled data to locate potential depressed users.

Published: February 2021

Abstract
We presented a miniaturized patch antenna with enhanced bandwidth. Reactive Impedance Surface (RIS) was introduced instead of the traditional metal floor, and bandwidth enhancement is realized by loading slotted parasitic patches. The reference antenna and the antenna 1 loaded with the parasitic patch are designed, that impedance bandwidth changed from 8.5% to 23.6%, the peak gain and the front-to-back ratio was also improved by 2.2dBi and 7.8dB respectively; The metal floor of antenna 1 was instead by using RIS periodic structure to design Antenna 2. The absolute bandwidth of both antenna 1 and antenna 2 is about 1GHz. Antenna 2 is 22.4% smaller than the reference antenna and 28.6% smaller than antenna 1. The simulation results show that the proposed bandwidth enhancement and miniaturization methods are effective and ensure a certain improvement in gain.

Authors: Sutrisno A T , Yulianti L P , Harlili  
Published: February 2021

Abstract
Food allergy and anaphylaxis are known to keep increasing in prevalence for over the years. Various efforts have been made to provide the solutions but they have not been proven very effective while on the other hand technological solution has not yet been much involved to support them. The main problem with food allergy is that people find it hard to access the information of complete ingredients, food-making process, and shared equipment that might be used in the process. The information is regularly needed by people with food allergy to determine whether the food is safe to consume or not. This paper will explain how the problems are solved by designing a food allergy information application using user-centered design (UCD) approach to facilitate the user needs with Gojek application as the study case. The outcome of this research is a high-fidelity prototype of the application. Usability testing is conducted for the prototype by using parameters such as completion rate, System Usability Scale (SUS) questionnaire, and User Engagement Scale-Short Form (UES-SF) questionnaire with corresponding results of 100% completion rate, 85.4 SUS score, and 4.23 UES-SF score which shows that effectivity and engaging as usability and user experience goals are fulfilled to answer the user needs.

Authors: Moravec Vojtěch , Markonis Yannis , Rakovec Oldrich , Svoboda Miroslav , Trnka Miroslav , Kumar Rohini , Hanel Martin 
Published: February 2021

Abstract
The recent dry and warm years in Europe are often assessed as extreme in terms of socio-economic and environmental losses. However, the impact of a drought is a function of its duration. This fact needs to be considered in the evaluation of a drought. In this study, we use a hydrological model to analyze the 2018 European drought, an event that significantly affected vegetation. We show that the severity of the soil moisture drought is high in Central Europe and Mediterranean, but it does not reach the levels observed in the first half of the 20th century. Nevertheless, we demonstrate that when the multi-year 2014–2018 period is considered, its soil moisture drought severity is exceptional in a 253 year period, especially for Central Europe. While single-year droughts can be sustained by ecosystems like forests, the repeated stress exposure of such multi-year droughts may have significant impacts on their functioning. This is already evident in some regions of Central Europe, e.g. in the Czech Republic, Germany, and Poland.

Published: February 2021

Abstract
The paper investigates the barriers to the implementation of sustainable facilities management practice in higher institutions of learning. An integrative literature review was conducted to identify the barriers associated with the implementation of sustainable facilities management practice in higher institutions of learning. Findings from the literature reviewed thus far indicate that the lack of knowledge, senior management commitment, time and financial constraints, and lack of capability are major barriers to adopting and implementing sustainable facilities management. However, there is acute scarcity of relevant information for the local context. There is a need to address the barriers of implementing sustainable facilities management principles in higher institutions of learning. Especially in the local context, there is a need for empirical studies for adequate comparison and specificity of results. The paper will be informative on the current barriers of implementing sustainable facilities management practice in higher institutions of learning, and provide a strong basis for empirical research in this area.

Authors: Dlamini M , Cumberlege R 
Published: February 2021

Abstract
The construction industry is negatively affected by cost and time overruns which further negatively impacts the contractual stakeholders. Construction delays and cost overruns are a global phenomenon since one of the major problems in the construction industry involves unexpected incurred costs and late delivery of projects. The success and failure of any project depends upon many factors and the Project Manager is considered to be the key contributor to the success of any project, as well as to guide the team members to achieve the client satisfaction. In addition, the roles, responsibilities, duties, and competencies of Project Managers have a direct impact on successfully completing construction projects on time and within budgeted cost. The study aimed to find the key competency skills that the Project Manager must possess to mitigate time and cost overruns. A quantitative research approach was adopted to determine the key competency skills of a Project Manager with respect to cost and time delays. A web-based questionnaire was published in the Eastern Cape Masters Builders Association (MBA) bulletin aimed at contractors registered with the association. The results revealed that the key competencies required to mitigate for cost overruns are comparable to those required to mitigate against time overruns. The study investigated the need for project managers to better equip themselves with key competency skills to perfom optimally to reduce the occurrence of cost and time delays on construction projects. The aim of this research was to assist Construction Managers to choose the right candidate as a Project Manager. It would also assist inspiring Project Managers to acquire the key competency skills. The paper responds to the conference theme given that the reduction of cost and time overruns promotes the sustainability of the Built Environment.

Authors: Leśniak A , Plebankiewicz E , Kozik R , Amanowicz-Marcinkowska K 
Published: February 2021

Abstract
The local spatial development plan is an instrument of spatial policy which aims at shaping spatial order. The local plan includes solutions ensuring protection against emerging pollutants, as well as restoring the environment to its proper condition and setting the conditions for the implementation of projects, enabling optimal effects in the field of environmental protection. Land use and land development should also ensure the preservation of all landscape values as much as possible. When creating and adopting a local spatial development plan, a municipality as a local government unit must take into account both public and private interests. The paper attempts to answer the question whether city planning has an impact on investors’ activity on the real estate market. Four selected cities located in different parts of Poland were analysed. The authors proposed determining the investor activity indicator as a measure of this impact.
Analysis on the Relationship between Farmers’ Ecological Protection Behavior and Well-being in Qinling Region
Authors: Qiu Yutong , Chang Yaoyin , Hou Yilei 
Published: February 2021

Abstract
How to arouse the enthusiasm of farmers for ecological protection is an important issue to coordinate protection and development. Therefore, it is necessary to explore the interactive relationship between farmers’ well-being and cognition, attitude, and behavior of ecological protection. Based on 618 data collected in a survey in The Qinling Mountains in 2018, this study establishes a structural equation model, puts forward and validates theoretical hypotheses about the interaction between farmers’ well-being, protection cognition, protection attitude and protection behavior. The results show that: protection cognition and attitude have a significant positive effect on protection behavior; protective attitude plays a limited mediating role in the path of cognitive influence on behavior, while well-being plays an important role in the path of attitudinal influence on behavior; “living conditions” and “health status” have the greatest impact on the well-being effect. The conclusion is that the well-being effect of farmers with a positive attitude towards protection is usually stronger, and the higher well-being effect has an incentive effect on the ecological protection behavior of farmers.

Abstract
Fertilizer nutrient loss by surface water contribute to eutrophication becoming one of the international problems. In order to study the effect of application of organic fertilizer on N/P loss in purple soil, an indoor simulating artificial rainfall experiment and in-situ natural rainfall experiment experiment was conducted in Chongqing, southwestern China. The result shows that TN(total nitrogen) loss in the simulation rainfall experiment was in the order of cow dung>compound fertilizer>chemical fertilizer>biogas slurry>oil cake>blank, whereas, TP(total phosphorus) loss was in the order of cow dung>chemical fertilizer>compound fertilizer>oil cake>biogas slurry>blank. TN content form organic fertilizer treated soil in the in-situ runoff test were lower than in chemical fertilizer treated soil at first, whereas the proportion of TN content form organic manure was increase and even higher than that form chemical fertilizer overtime. Grain nitrogen was the dominant nitric species in runoff under 15°, whereas Ammonium nitrogen was the dominant nitric species in runoff under 5°. The slope significant affect grain nitrogen content in runoff, while it has little effect on soluble nitrogen. Soluble phosphorus content in chemical fertilizer treatment was higher than that in organic fertilizers treatments, while particulate phosphorus concentration in chemical fertilizer treatment was lower than that in organic fertilizers treatments. Particulate phosphorus is the main form in runoff simulation, accounting for 50%∼90% of total phosphorus; while soluble phosphorus was the dominant phosphoric species with the slope, rainfall intensity and fertilizer dosage reduced. Rainfall intensity could increase P concentration in runoff. There was a significant positive correlation between the TN and TP concentration in runoff and rain intensity, fertilizer addition level, slope.

Authors: Huang Liqiong , Zhang Zhenghui , Xiang Pengzhi 
Published: February 2021

Abstract
With the increasingly serious situation of air pollution, catalytic conversion has become a hot research direction, and the efforts were focused on the preparation of catalysts greenly and effectively. The catalysts were prepared by plasma-assisted method in our work. Different gases were introduced to the plasma system. The catalyst treated by a mixture of nitrogen and hydrogen plasma (PNH) catalyst behaved badly in activity and coke resistance, but the hydrogen plasma (PH) and nitrogen plasma (PN) samples displayed fine activity. The catalyst treated by nitrogen plasma (PN) exhibited high activity compared to the C sample. The amount of coke over PN sample was less than that of the NMA-PH catalyst. Whereas, the PN catalyst presented as good activity and coke resistance in carbon dioxide reforming with methane as the conventional calcined catalyst.

Published: February 2021

Abstract
In recent years, antibiotics have been widely used to treat some human and animal diseases, which due to their large production and usage. The antibiotic pollution in the environment has attracted more and more people’s attention. As a large country in the production and use of antibiotics, antibiotics has been detected in various environmental media in China, even in drinking water. However, drinking water is closely related to the health of residents. It is very necessary to understand the occurrence of antibiotics in drinking water and assess the health risk. Therefore, in this study, taking a city in southern China as an example, it was detected that the concentration of antibiotics in the drinking water was 226.8∼498.1ng/L, and the main pollutants were tetracycline and quinolone antibiotics. The non-carcinogenic risk assessment shows that drinking tap water for residents in this area will not pose a risk to their health.

Published: February 2021

Abstract
This article aims to study the reduction design of fragile buffer packaging under the concept of green development. Through the analysis of the advantages and disadvantages of existing cushioning packaging materials, in view of the current situation that corrugated paper cushioning packaging uses a lot of materials, and the cumbersome molding has led to the wide application of plastic packaging materials, the design principle of fragile cushioning packaging under the green development concept is proposed. Taking glass cups as the design object and corrugated paper as packaging materials, three different prototype glass buffer packagings were designed. The reduced-quantity design of corrugated cardboard buffer packaging provides a solution for replacing plastic with paper. From an environmental and economic point of view, reduced-quantity buffer packaging is feasible.
