ABSTRACTFour decades of advanced research about Non-Conventional Materials and Technologies (NOCMAT) such as bamboo and composites reinforced with natural fibers have shown that it is now possible to produce and use high performance NOCMAT. Bamboo and composites reinforced with vegetable fibers are capable, meeting most engineering demand in terms of strength, stiffness, toughness and energy absorption capability. The greatest challenge of the 21st century is the need for cost-effective, durable and eco-friendly construction materials that will meet the global needs of infrastructure regeneration and rehabilitation which alone can enhance the quality of life for all the people of the world. This paper summarizes some results of judicious combination of different matrix reinforced with vegetable fibers, especially bamboo. These sustainable ecological materials are strong, ductile and capable of absorbing large amounts of energy. They could find extensive applications in the engineering particularly in developing countries. Specifically, the development of durable composites reinforced with vegetable fibers and bamboo poses an important challenge to the science and skills of engineering. This challenge could create the most useful, eco-friendly construction materials backed by an endless supply of renewable natural resources. In addition the paper presents results of some ongoing research concerning bamboo and how vegetable fibers such as hemp plant, before the invention of Nylon was the most used materials in all aspects of human life around the globe and why it was banned.

The presence of landmines and Explosive Remnants of War (ERW) in a place represents a major threat to civlian and affects the rebuilding process and the life of the people at that place. Hence, one of the fundamental goals of humanitarian demining is to detect and clear all forms of danger from infected areas efficiently, reliably and as safely and as rapidly as possible while keeping cost minimized. Although demining has been given top priority, currently mine’s clearing operation is a dangerous, complex, time consuming, slow, labor-intensive, and costly operation. The currently available technologies are not suited to achieve the objectives of humanitarian demining. In the context of humanitarian demining it is essential to have a reliable and accurate sensor and/or an integration of heterogeneous/ homogeneous sensors with efficient and reliable data fusion and processing technique that can quickly discriminates mines from innocuous buried objects. In addition, it is necessary to overcome the constrain on the resources by developing innovative, cost effective and practical technology inspired by locality and real minefield needs to help in speeding up the demining process and enhance accuracy, productivity, operation and personnel safety, achieve higher quality of the service, and contribute to local economy.This chapter presents the facts and problems associated with landmines and their impact on health, economy, land and environment along with the difficulties in detecting and removing them. It highlights the main requirements for humanitarian demining action plan and list up solutions and priorities.Then, it presents the challenges facing technological development in different directions and concludes with the suitable actions to save human and environment from such complex problem facing humanity.

High-performance concrete (HPC) prepared on the basis of eugenic considerations (cost-effectiveness and life-cycle length) is proposed to resolve actual concrete problems. HPC is safe, durable, workable, economical, and ecologically sound. Concrete in Taiwan is always designed with large amounts of water and paste (even though it is generally accepted that the concrete will tend to crack and deteriorate). Therefore, HPC with fewer problems is the target of ongoing research. Eugenic HPC is produced from ordinary concrete, superplasticized concrete, pozzolanic concrete, and high-flowing concrete. Without the drawbacks of past forms of concrete, eugenic HPC is a better construction material on the basis of individual material characteristics. The characteristics of eugenic HPC are presented and illustrated by two high-rise buildings in Taiwan constructed with high-flowing HPC.

The health sector is an important part and must be considered by the Government of Indonesia. The people who really need health are the people, both rural and urban. Public health is an indicator of the quality of human life which is strongly influenced by environmental conditions in an area. One sign of low environmental health is air pollution. Air pollution is defined as the presence of foreign materials or substances in the air which causes changes in the composition (composition) of the air from its normal state, which can cause several diseases such as respiratory diseases. Tuberculosis (TB) infection is a disease whose spread is influenced by environmental and behavioral factors. In addition, reduced levels of oxygen in the environment are also caused by air pollution. For that we need innovations that can improve environmental health so that people's welfare can increase. For this reason, a rural innovation program related to the health of rural communities, especially in the health of respiratory diseases, in this case is TB, was created, which can improve the quality of environmental health and also the welfare of the community. In addition, it also identifies the influence of innovative oxygen enhancement programs by planting trees in rural communities. This research was conducted to identify rural innovation programs related to rural public health, especially on respiratory disease health, and also to identify the effects of innovative oxygen enhancement programs by planting trees in rural environments. The method used in this research is descriptive qualitative method. As a result, there was an increase in the percentage of TB sufferers because of the Ketok Pintu Sekaput program. In addition, the Shodaqoh Oxygen program, which was carried out in villages in Banyuwangi Regency, succeeded in planting 7,444,764 trees in 2018. Suggestions for the future, it is better for the community to always practice clean and healthy living, and better prevent preventive and make tree planting programs. at the RW level so that they can provide seeds according to the needs of each area.

<p><strong>Abstract.</strong> The geodetic-photogrammetric test field at the industrial monument Zollern colliery in Dortmund offers a scenario for carrying out geometric and radiometric tests of UAV systems. The foundation for this builds a geodetic precision network (position and height accuracy approx. 2&amp;thinsp;mm) with a total of 45 ground control points, distributed over an area of approx. 7 hectares. Within the scope of a campaign carried out in autumn 2017, various UAV sensor systems were tested under comparable conditions. Within this paper geometric investigations of two current DJI cameras, Zenmuse X4S (20 Mpix) and X5S (20.8 Mpix), as well as a Phase One IXU 1000 (100 Mpix) are presented. While the Zenmuse cameras reflect the current state of development of the manufacturer DJI, the medium format camera system from Phase One is primarily settled in the classic aerial segment. However, the desire for increased measurement accuracy (e. g. for engineering applications) also makes such a high-performance sensor interesting for UAV applications.<br />In addition to the configuration of the test field, the system comparison requires identical parameters for flight planning, in particular image overlapping, a complete cross flight configuration at different flight altitudes and the definition of a uniform ground resolution (GSD&amp;thinsp;=&amp;thinsp;14&amp;thinsp;mm).</p><p>The investigations show clear differences in the achievable quality of the cameras. Though the high-priced Phase One system shows the best results, the most cost-effective system, the Zenmuse X4S, delivers only slightly worse results. In contrast, the Zenmuse X5S performs significantly worse than the other systems, mainly resulting from the mechanically unstable camera concept with interchangeable lenses. Finally, the comparison of the software products Pix4D Pix4Dmapper, Inpho UASMaster by Trimble and Agisoft PhotoScan partly shows significant differences in the results of image orientation. In particular in settings with sparse GCP usage the results vary considerably, indicating different strategies on how the residuals are distributed and the datum is defined, mostly Pix4Dmapper outperforms the others. In better GCP configurations there is no significant difference between Pix4mapper and Agisoft PhotoScan, while UASMaster does never deliver the best results.</p>

Abstract: Tons of waste is produced in the world on every day basis which sometimes gets really hard to manage and. The waste from demolished structures is one of them. Recycling waste consume energy and produces pollution that can lead to many adverse effects on the environment and human life. The disposal of waste is also very dangerous for the environment. Using waste materials like waste aggregates, broken bricks, stones and other material in concrete can help in eliminating the waste and save the environment getting polluted. It is also very much economical and encourages green concrete industry. The literature study consists of testing of high-performance concrete using waste aggregates by replacing 100 % natural aggregates. Also, silica fume and plasticizer are used as admixture to obtain more effective results. The tests were carried out on 3, 7 and 21 days of curing. The results were tallied using graphs between comparison of compressive strength and tensile strength of natural and recycled aggregates. The cement and natural aggregates and sand was obtained from a local store in a nearby market. The recycled aggregates were obtained from a nearby demolished building. The quantities were taken in a proper proportion according to IS codes to avoid any defects while constructing the cubes and while curing and performing various tests.
