Abstract This technical brief is an attempt to report a case analysis of Engineering for Global Development (EGD) research from India. As a part of the engineering design and research project, two models of Improvised Betel Nut Cutter (IBNC) are designed, manufactured and field-tested. Engineering ethnography is adopted as a research tool during the design process of IBCN. It facilitated the participation of local stakeholders in the design process which is found to be effective for contextual understandings of the target community's needs, aspirations, constraints and socio-cultural norms and values. The technological intervention is expected to solve the problems like finger cuts, health drudgery (musculoskeletal pain, back pain, etc.) of the women involved in the supari business in Assam, India. It will also improve productivity and efficiency in the supari cutting practices of women. This case analysis depicts the effectiveness of trans-disciplinary effort in solving complex engineering problems at the bottom of the pyramid (BOP). Evidence gathered from this study is expected to be a useful resource for future endeavours in EGD research.

The development of China’s new urbanization has driven the rapid increase in large complex engineering projects, which have the characteristics of large-scale investment, long-term construction, and wide social influence, easily causing benefit conflicts among relevant stakeholders, and breaking out social stability risks. In the previous research, the risks of large complex engineering projects mainly concentrated on the assessment of economic risk, schedule risk, etc. However, there were few studies on social risks, and they did not consider how the risks spread on the complex networks based on the social connections such as interpersonal relationship. From the subject of social stability risk diffusion of large complex engineering projects, this paper constructs a related risk diffusion model based on the SIR model to analyze risk diffusion mechanism. Through NetLogo simulation platform, the model is placed under a small-world network environment that is closest to the topology structure of real social interpersonal relationship network for simulation research, aiming to find out key factors of social stability risk intervention for large complex engineering projects, which greatly contributes to the social stability risk management of large complex engineering projects.

Nowadays the area of cities is almost everywhere increasing - the territory urbanization is developing. At the same time, due to lack of land resources, the underground space development intensifi es, and the underground construction volume increases, i.e., underground urbanization takes place. This process has undoubtedly positive results, as it can help solve territorial, transport, environmental and other problems of cities while preserving the unique appearance of buildings in the historical centers of cities. At the same time, some engineering and geological processes may be activated as a negative underground urbanization result. The article deals with underground urbanization history in Samara and defi nes its main stages. More than one million people live in Samara city, subway line was built, there are subway objects of industrial and defense importance (bunkers) reaching considerable depth. Active underground construction can lead to geological processes strengthening (weathering, karst formation, suff osia, etc.), change of strength properties of rocks, violation of natural hydrological regime of the territory. The territory of Samara has an inhomogeneous geological structure and complex engineering and geological construction conditions. Seven engineering-geological districts have been identifi ed and studied, on the territory where underground construction development can lead to diff erent, including negative, consequences.

Abstract In modern complex engineering-geological conditions of cities, the growth and scale of development of dangerous natural processes and phenomena can be traced. In many ways, the reasons for this are not only technogenic load on the soil, but also changes in climatic factors. Buildings and objects exposed to hazardous factors of hydrogeological processes are becoming increasingly vulnerable to their impact, which can lead to catastrophic consequences. One of the main conditions for increasing the stability of objects is the adaptation of existing methods or approaches to assessing natural hazards that have a negative impact on the physical state of such objects. The authors of the article propose an adaptation of the international INFORM approach in order to assess the hazard level of natural processes and phenomena in built-up areas. The task is also to develop a methodology for assessing the physical state of objects exposed to such processes and phenomena. To solve this problem, the study examines the practical aspects of applying the principles of the Weber-Fechner law in determining the state of the structural parameters of buildings that are under the influence of negative factors of hazardous natural processes and phenomena. The study is based on the principle of changing the category of the physical state of objects from changes in the level of exposure to hazardous factors of natural processes and phenomena.

Designing of a ground cloth is the most responsible stage as destruction or inadmissible deformations of a ground cloth connected with design errors lead to decrease in reliability of all constructive elements of highways, increase in expenses for maintenance of a standard technical and operational condition of road clothes, culverts, elements. arrangement, etc. Insufficient strength of the ground structure is one of the causes of deformations and destruction of the structure of the pavement, which leads to deteriorating traffic conditions, increased damage from traffic accidents, increased cost of transportation and more. At the same time, the normative documents on road design do not contain any regulations on the procedure and methods of calculating the road surface in difficult conditions (on weak, subsidence soils, in rocky soils). Therefore, in order to further develop the list of mandatory calculations during the design of the ground, it is necessary to analyze and generalize the regulatory framework for the construction of the ground of public roads, to determine the requirements for the design of the ground in complex engineering and geological conditions. The purpose of this study is to generalize the regulatory requirements for the design of the ground of public roads in complex engineering and geological conditions. According to the results of the analysis, it is established that in the normative documents on the design of the road surface in difficult engineering and geological conditions there is no regulation on the procedure and methods of calculating the road surface in difficult conditions (on weak, subsidence soils, in rocky soils). Therefore, there is a need to develop a national standard for the design of the road surface. In the future it is necessary to summarize the existing methods of calculating the road surface, to develop a list of mandatory calculations during the design of the road, to establish requirements for the principles and procedures of road construction, to determine the boundary conditions of the road and their criteria.

Abstract: Programme outcomes (POs) are the attributes that reflect the student skills expected to be acquired upon graduation. The Engineering Accreditation Council (EAC) under Board of Engineers Malaysia requires 12 POs with complex engineering problems (CEP) and knowledge profiles to be incorporated in engineering programmes. Despite considerable research on outcome-based education (OBE), the OBE implementation with regards to the PO attributes and domains incorporating CEP characteristics are still questionable and vaguely implemented by the programmes. This paper presents two PO attributes related to problem solving and development/design for solution based on the perceptions of 301 engineering students in Malaysia. This paper aims to determine the student’s level of understanding on the PO learning domain and to analyze significant factors contributing to their PO attainment. A quantitative method using a questionnaire survey was adopted targeting a random probability sampling of respondents. Descriptive (percentage frequency, relative importance index) and statistical analyses (reliability, normality, correlation) were used to analyze the data. The findings show that the students perceived both POs as cognitive domains and they believed that lecturer’s roles in facilitating students on the subject matter has contributed significantly to their PO attainment. This study is limited to an engineering programme from one institution of higher learning (IHL) in Malaysia. However, the findings provide important insights on the students’ level of understanding of PO attributes and the OBE practices on CEP in the programme. This study can be extended to other IHLs to gauge the students’ understanding related to other PO attributes stipulated by the EAC.   Keywords: Programme Outcomes, Cognitive Domain, Problem Analysis, Design of The Solution, Engineering

Abstract: The Engineering Accreditation Council Standard 2020 requires the stipulated 12 programme outcomes that address complex engineering problems (CEP) and complex engineering activities (CEA) to be incorporated in the engineering programmes. However, the implementation of outcome-based education with regards to CEP and CEA is still in the infancy stage. This study was carried out to give an overview of the implementation of complex engineering problems and activities in Malaysian engineering programmes in relation to the types of assessment used to address CEP and CEA, and the typical weightage and taxonomy level of CEP and CEA employed in these assessments. A survey questionnaire was administered to 256 engineering educators from 25 universities to enquire about the implementation of CEP and CEA in their engineering programmes, particularly in the online teaching and learning during the Covid19 pandemic. The findings showed that most of the programmes addressed complex engineering problems in assignments or projects as compared to final examinations or mid-term tests. Complex engineering activities were found to be addressed in Final Year Project, Industrial Training and Integrated Design Project and laboratory courses. The findings in this study could act as a guideline for educators to enhance the teaching and learning activities incorporating CEP and CEA elements, and hence facilitating the continual quality improvement for an engineering programme.   Keywords: Complex Engineering Problems, Complex Engineering Activity, Engineering Accreditation Council, Outcome-Based Education
