A study to examine ways to increase the prevalence of courses in environmental studies using environmentally conscious technologies
Authors: Tanaka Shunya , Nakajima Yusuke 
Published: August 2019

Abstract
Over the past few years, an increasing number of schools in Japan have been certified as eco-friendly. These schools incorporate environmentally conscious technologies in order to reduce energy use in school structures and to promote environmental education. The current study ascertained the use of environmentally conscious technologies in environmental education in elementary and middle schools, and it proposed an environmental studies program to increase the prevalence of environmental education. A course in environmental studies was conducted during Open House week, students and their parents were surveyed, group interviews were conducted with teachers, and the course was assessed using an environmental efforts worksheet. Survey results revealed that over 90% of parents considered the course in environmental studies necessary. Group interviews revealed that a positive aspect of conducting a course in environmental studies during Open House week was that it effectively increased the prevalence of such courses. Interviews also revealed several problems: the way in which to relay the course guide and course data need to be described in detail, and the course guide needs to be further simplified. The environmental efforts worksheet, schools that implemented the course reduced CO2 emissions (kg/mo.) by an average of about 1.6 t.

Abstract
In Japan, late elderly people (≥75 years old) tend to be unable to create social groups, because they have decreased body functions and structures. Previous studies have shown that those who are able to visit so-called “third places”, places such as cafes, libraries, and parks where people can go and spend time freely, are significantly more outgoing and have more conversations with people. The aim of our survey was to clarify the effects of the third places on the need for long-term care and support in the late elderly. We conducted a questionnaire survey for 3 weeks from September to October 2016. The subjects were late elderly people located in Kitakyushu, Fukuoka. Survey questions included their utilisation of third places, their neighbourhood environment and their health condition. A total of 629 questionnaires were distributed by mail, and 349 were correctly completed (valid response rate = 55.5%). A total of 58.6% of respondents could identify their third place. Of those, 75.6% visit their third place more than once a week. We conducted logistic regression analysis to clarify the effect of a third place on the risk of being homebound (i.e., going out less than once a week), social isolation (having a conversation less than once a week), and long-term care/support needs. The analysis model considered age, BMI, marital status, body pain, household, educational attainment, and length of residence in the target area. The resulting odds ratio (OR) for the risk of being homebound was 8.46 (p < 0.01), for social isolation was 4.40 (p < 0.01) and for long-term care/support need was 3.70 (p < 0.01). These results show that not having a third place is strongly related to high risk for needing long-term care/support.

Abstract
In Southeast Asia, reduction of energy usage is a necessity because of an increasing trend in building energy consumption. The building envelope performance strongly affects the building’s energy performance necessitating it consideration in energy usage studies. Many studies have been conducted that have encouraged the growing use of green materials in Southeast Asia. However, the studies that have focused on the building envelope are few. It is, therefore, unclear whether the adopted products would perform at the level for which is decided at designed. This study analyses how to rate material performance and the glass and frame production process along with the performance guarantee system used on building envelopes in Thailand located in Southeast Asia. Data were collected in a literature review and field survey. The field survey is an interview survey which was conducted with academicians who focus on the glass industry, architects and façade contractors, and a factory survey which was conducted in a glass factory and aluminium factory in Thailand. As a result, this study presented the material performance decision factor, the production process, and the product testing phase including checking of production performance and the practically referred standards.

Published: August 2019

Abstract
The United Nations has projected that over two-thirds of the world’s population will be living in cities by 2050. With the desire to reach the goals of higher economic growth, Indian cities are facing rapid urbanization leading to high density living and decreasing green spaces threatening the living conditions of the urban areas. These conditions drastically changed in the recent past with the increase in temperatures and vehicular pollutants devoiding the natural systems in the cities. The scarcity of the natural resources such as water, fresh air and green spaces at one hand and the rapidly depleting resources at the other hand, the process of sustainable development and creating urban green infrastructure is becoming a challenging task for Indian cities. The major factors influencing the urban environment such as climate, water resources and air quality and other multi folded issues can be addressed through setting up of green infrastructure at various scales. The recent trend in the changing perspectives of landscape planning in Indian cities and addressing the loss of natural infrastructure in the cities has to be balanced by creating adaptable built environment with green infrastructure such as urban farms, urban forests and community farms in urban spaces as part of existing and evolving city fabric. The challenge is that such green infrastructure solutions are failing to find their way into practical form. The study focuses on analysing the parameters to incorporate sustainable green infrastructure models, challenges and strengths in adopting successful models into the city fabric. A study of various existing models at different scales from cities of Bangalore, Hyderabad and Visakhapatnam are discussed to give insights into the adaptability aspects of the model with reference to their respective urban context.

Published: August 2019

Abstract
Stick-slip vibration is likely to occur while drilling in hard formation and soft-hard interbedded formation, especially when PDC bit is used, which further results in lower ROP and short footage. In this study, Gyro Shock-damping Tool and optimization PDC bit design were tested to reduce the stick-slip vibration and lengthen bit life while drilling in granite buried hill formation. Main parameters of the PDC bit include: 8 blades, short parabolic profile, Trident IV PDC, 10mm, 13mm cutter, totally 90 cutters, back rake of 19°-23°, double row of cutter (back row is impregnated string, with the height difference of 0.5mm). Gyro Shock-damping Tool combined with customized PDC bit was tested in 630-869m granite formation of a well in Chad, 239m footage was done in 54hrs, with a ROP of 4.44m/hr. In comparison, in an adjacent well, only 11m footage was completed with 3 PDC bits at the ROP of less than 1.23m/hr. Compared with some other adjacent wells drilled by 43 tri-cone bits, the specially designed bit increased by 97.33% in ROP and 54.19% in footage on average. All these prove that the technology outperforms the other bits, and can be used widely in granite buried hill horizontal well, hard formations and hard –soft interbedded formations.
Environmental cost assessment model of land use Project
Authors: Guo Jiaxi 
Published: August 2019

Abstract
With the improvement of human understanding of ecological environment, scientists at home and abroad have established a series of models to assess the environmental costs of land use projects. Most of the domestic research is based on the ecosystem of Xie Gaodi’s Static value model. His model mainly considers the value of the ecosystem occupied by the project. However, on the basis of this model, this paper will construct the environmental degradation model from another angle. The new model takes into account not only the value of the ecosystem occupied by the project, but also the continued loss of the project to the external environment. This model is a more comprehensive assessment of the cost of environmental losses for land-use projects.

Abstract
A number of super high earth-rock dams will be built in China in the near future. Deformation control is the key issue in the safety construction and operation of these major water conservancy projects.In this paper, the effect of stress loading process on the subsequent rheological development is studied, and a new accumulation rule of rockfill rheology is proposed, that is, the current rheological variable of rockfill unit at a certain time is equal to the hardening rheological variable that can cause additional hardening of rockfill at that time.Then, the influence of stress unloading process on the subsequent rheological development law is further studied. It is found that after stress unloading, there are positive rheological zone, no rheological zone and reverse rheological zone in the rheological behavior of rockfill material. The rheological accumulation rule proposed in this paper is also applicable to the case of stress unloading.

Published: August 2019

Abstract
The major difficulty in classifying the type of fine-grained patterns is that the visual differences between subordinate types are probably very subtle, which, however, may be extremely big in the same kind. A fine-grained pattern recognition algorithm is put forward based on the attention pattern-generated model in this article. First, extract high dimensional characteristic pattern from the image via CNN. Then apply several separators to outputting category predictive activation volumes on the characteristic mapping. After that, polymerize these activation volumes to obtain attention mapping. As for the fine-grained recognition, we use the generated attention pattern to tailor and zoom the intentional area so as to carry out multi-scale prediction. This article has been assessed on CUB-200-2011, FGVC-Aircraft, Stanford Cars, and the model mentioned in this article is more superior than baseline multi-scale resnet50 by more than 2%. Attention pattern generated from the model is helpful for other models to increase their recognition accuracy as well.

Abstract
In order to determine whether there is a threat to soil nutrient content by long-term no-tillage cultivation in loess plateau, a suitable high-yield and high-efficiency tillage technology system is established. This study was conducted in the Changwu Loess Plateau Agro-ecological Experiment Station of the Northwest A&F University in Changwu County, Shaanxi Province. The experimental field for no-tillage cultivation was selected for three consecutive years. In September 2015, no-tillage and tillage were carried out separately before winter wheat planting. And rotary tillage 3 kinds of farming treatment. After harvesting of winter wheat in 2016, the contents of available phosphorus, available potassium in 0∼30 cm soil layer under different tillage methods were analyzed. The results showed that in the 0∼30cm soil layer, the contents of available phosphorus and available potassium in the soil under three tillage methods decreased along the profile. The contents of available phosphorus and available potassium in 0∼10 cm soil layer were significantly higher than that of tillage and rotary tillage (p<0.05). The contents of available phosphorus and available potassium in soil of 10∼30cm soil were ploughed tillage > rotary tillage > no-tillage, and there was no significant difference among the three tillage methods in 10-20cm soil layer.

Published: August 2019

AbstractThe deepening understanding of the geological structure of large paleo-uplift in the basin is often accompanied by important oil and gas exploration discoveries. The abundant oil and gas exploration results in the early stage show that the luzhou paleo-uplift is one of the important petroleum accumulation structural units in the sichuan basin. At the same time, the formation and evolution of luzhou ancient uplift were also affected by a variety of geological factors. It is a joint response of the internal deformation of the Yangtze plate and the orogenic movement of the peripheral block in the indosinian period, and a natural place to study the basin-mountain coupling relationship and the basin superposition transformation process. By means of a large number of seismic reflection profile and drilling data, combined with field exploration and other data, the temporal and spatial distribution characteristics of luzhou ancient uplift are described in detail. Combined with the tectonic background of the study area, the formation of luzhou ancient uplift was further analyzed, and the genetic mechanism model of luzhou ancient uplift was proposed. Through analysis, it is concluded that the indosinian luzhou ancient uplift developed in the southeast of sichuan basin, and its long axial strike is from northeast to southwest, which is a typical compressive and superimposed ancient uplift.

Authors: Wu Pengpeng , Li Peng 
Published: August 2019

Abstract
With the development of society and the progress of science and technology, people’s living standard has been raised gradually. Behind these, it the development and utilization of energy. China is a large coal production country. Coal is the basic energy in China, and will be the major energy in the current decades and even in the coming decades. As coal is a non-renewable resource, plus the irrational exploitation in the first few years, a great deal of coal resources were wasted, which is contrary to the sustainable development strategy of the country. In recent years, to respond to national policies, vigorously promote sustainable development strategy, improve energy efficiency, major mining areas are enhancing the mining of residual coal, especially in isolated island state of coal. At present, there are some effective safety measures for mining coal under the condition of isolated island in China, but most of the safety research focuses on the mining face, but only a few studies focus on the safety of roadway. Through investigation, it is found that there are a series of problems in roadway driving and working face mining, such as strip wall and coal cannon. This seriously restricts the mining speed of isolated island working face, and always threatens the safety of workers. In this paper, the stress distribution characteristics of coal body under isolated island state are analyzed by numerical simulation. On the basis of this, the stress distribution characteristics of roadway surrounding rock and working face mining are analyzed, and the stress variation law is summarized. It is found that there exists a stress concentration zone in the coal pillar under the condition of isolated island. The stress concentration zone is mainly affected by the geological conditions of isolated island. There is a second stress concentration zone 7 m away from the side of the roadway, which is smaller than the stress concentration zone in the protected coal pillar, but the dynamic change is larger and the stress concentration zone moves with the advance of the working face because of the influence of mining in the working face. Therefore, in the aspect of maintaining the stability of roadway surrounding rock, the effective maintenance mode is determined according to the stress distribution characteristics and variation law of roadway surrounding rock under isolated island working face.
