Authors: Abunawas Abunawas , Amir Amriani , Hendrianto El
Published: May 2024

The article on the modernization of Indonesian law through revision of the Undang-undang Hukum Perdata (KUH Perdata) aims to analyze the relevance of the Civil Code to current conditions and identify articles in the Civil Code that are no longer relevant to current developments. The research was carried out using a qualitative descriptive method, focusing on a problem based on facts obtained through observations, interviews and studying documents or references that are relevant to the topic being written. This research was carried out by collecting data from various sources such as literature, legal documents and previous research results that are relevant to the data needed. Furthermore, the data obtained was then analyzed qualitatively by identifying patterns and themes that emerged from the data. This research also uses a textual and contextual approach in analyzing the Civil Code. The conclusion of this research is that the revision of the Civil Code is a necessity in adapting to the challenges of the times. In terms of legal and grammatical substance, those who still adopt the old grammar are no longer appropriate to the current Indonesian language context. Likewise, articles that are no longer relevant need to be updated to ensure that the law continues to function effectively in modern society. The revision of the Civil Code is not just an adjustment, but is also an important step in modernizing the Indonesian legal system as a whole

Feedback is information provided to a student related to their skills or demonstrated performance during the completion of a task, usually after instruction (Hattie and Timperley, 2007). Feedback has been identified as a factor that can influence student performance (Fui and Lian, 2018; Martínez and Vargas, 2014; Uribe and Vaughan, 2017; Wisniewski et al., 2020) by allowing the students to identify what they need to achieve success according to what is expected of them, self-evaluating their learning and thinking on their actions and consequences, allowing them to reach goals and objectives. Likewise, it has been identified that little or ineffective feedback can lead to school dropout (Wisniewski et al., 2020).

With the growing demand for sustainable accountability, the European Directive 2014/24/EU (EU 2014) pushes architects to deliver Building Information Models (BIM) as a part of procurement processes for public buildings. In the Netherlands, BIM model data is relevant to the building permitting process, which involves an environmental performance calculation (MPG). This assessment takes into consideration the embodied carbon of materials in a building. Although this analysis is performed by a qualified expert in late design phases, architects benefit from integrating carbon data in early de- sign decision-making. Design methods supported by Life Cycle Assessment (LCA) values are needed before involving expert collaborators, and not only when applying for a building permit.The existing carbon assessment tools require detailed data from BIM models, which are often not available at early de- sign phases. Simplified tools have been discussed in theory, and explored in their potential applications, however, there lacks scientific literature discussing the hurdles designers face in their attempt to create such tools in practice, for their in- ternal use throughout early design phases.This paper focuses on the architecture professional practice and design methods supported by digital and computational technologies, regarding embodied carbon data. It investigates the challenges in integrating embodied carbon data in the design workflow, through the development of a digital tool made by designers, for designers. This paper conducts an empirical investigation within a Rotterdam-based architecture office, with a broad portfolio in BIM usage and public building projects, to identify and categorize the factors affecting carbon data integration into the design workflow. It proposes a taxonomy of challenges within the architecture office, to better communicate the designer’s needs to the data providers and software developers with architects as a target user. Amongst the bottlenecks encountered are: access to data inclusiveness), data literacy and connecting data usage with design decision-making.
The Landscapes of Wind Energy Waste
Authors:   Pratt Institute, Zorić Dragana
Published: May 2024

Globally, wind energy is viewed as “carbon neutral”, recognized for generating clean, greenhouse gas-free electricity without an ecological footprint. Considered to be one of the most environmentally promising and economically viable sources of renewable energy, its growth worldwide has rapidly accelerated, spawned by governmental climate emergency response targets like Net Zero Emissions by 2050. Incentivized by markets, developments in technology have followed, resulting in massive increases in turbine size and capacity, despite challenges of delivery and distribution; these trajectories are poised to continue.With a lifespan of 20 to 25 years, a comprehensive life cycle analysis of wind turbine blades (WTBs) reveals a pressingenvironmental concern of their materials reuse (or disposal). Made of Glass/Carbon Fiber Reinforced Polymer, and fabricated to withstand immense wind force, both their material and assembly result in structural properties which currently preclude WTBs from being reused or recycled in a systemic, scalable way. Research and recent developments have resulted in targeted solutions which aim to change the stasis of key turbine component reuse. Challenging the perceptions of endlessly renewable energy and the fact that renewables are entirely carbon-neutral, this paper outlines factors that hinder large-scale reuse and recycling, touching on possibilities of the chemical and physical restructuring of the material; it focuses on possible upcycling options as a structural material in architecture and civil engineering, including large-scale use in the rewilding of waste landscapes.

Spatializing Reproductive Justice
Authors:   Columbia University, Roberts Bryony , Harkema Lindsay ,   The City College of New York, Brown Lori ,   Syracuse University
Published: May 2024

Coined in 1994 by a caucus of Black women activists, reproductive justice is the “human right to maintain personal bodily autonomy, have children, not have children, and parent the children we have in safe and sustainable communities”.1 After the overturn of Roe v. Wade, access to reproductive healthcare is radically restricted across the U.S., compounding systemic race, gender, and class-based inequities that have always made healthcare inaccessible for many. The landmark Dobbs v. Jackson Women’s Health Organization decision in 2022 rolled back nearly 50 years of reproductive rights protections and unleashed a plethora of laws that make it more difficult to access reproductive health care, riskier to assist those seeking care, and precarious to teach about issues of race, gender, and sexuality. As stated in the dissenting opinion by Justices Breyer, Sotomayor, and Kagan, “Whatever the exact scope of the coming laws, one result of today’s decision is certain: the curtailment of women’s rights, and of their status as free and equal citizens.”2 In the U.S. today, bodily autonomy and academic freedom are geographically situated. Within this context of curtailed freedoms, architects and educators must confront the spatial realities of these restrictions. New dialogues must emerge at architecture’s intersectional edges – between designers, activists, social justice advocates, legal experts, public health practitioners, and students – to explore how the built environment can better support human lives.

Climate change impacts are not evenly distributed across the globe. Inequities also emerge at a local scale where buildings have the most perceivable impact, affecting anything from access and continuity of the public realm to microclimates.Design decisions can exacerbate or mitigate microspatial inequities—i.e. significant local variation in environmentalhazard exposures, like heat, air pollution, and flooding. Green Infrastructure (GI) is a range of nature-based solutionswith the potential to mitigate environmental hazards. Decentralizing GI is critical to health and resilience, buildingredundancy and capacity through a distributed network of smaller system nodes that are less prone to cascading failures.Architecture projects can support decentralization, targeted mitigation, and incremental implementation; however theircontribution to urban resilience, health, and environmental justice needs to be better characterized to support rationalizedexpansion of such approaches. This requires ways to explore complex and dynamic interactions of buildings within and beyond site boundaries, including: (1) methods for measuring local variation in hazards at relevant spatial scales and (2) tools for modeling the impacts of interventions in inclusive conversations with local stakeholders. This research examines an equity-focused approach to co-designing GI in architecture projects, using data and tools to inform and measure the impact of individual building projects and, eventually, networks of projects. In collaboration with the city of Chelsea, MA, our transdisciplinary team is studying sensor networks and a participatory modeling process to demonstrate how architecture projects can generate and leverage local knowledge about microspatial inequities and mitigation by GI to advance broader community health goals. Co-design activities around one pilot site reveal how decentralization becomes a significant paradigm shift—even among practitioners—eliciting ideas about maximizing capacity, connectivity, co-benefits, and shared responsibility. This paper examines the term decentralization in a multidisciplinary discourse, shares lessons from a specific context, and discusses implications to architectural practice.

Published: May 2024

The International Union of Architects (UIA) designated 2022 as “the Year of Design for Health,” which emphasized the significance of health in architectural practice. As a signature event, UIA organized an international student competition, inviting college students to present innovative designs for a 30-bed rehabilitation center. One hundred seventy-five teams from 40 nations submitted their works, with five winners and seven honorable mentions awarded. This study amis to examine the current state of global Design for Health education, identify the strengths and weaknesses of student designs, and provide guidance for GUPHA and the UIA Public Health Group to develop evidence-based strategies that facilitate education in this field worldwide. Research Methods: Interviews with four jurors were conducted, and the jury’s evaluation notes, and competition report were analyzed. Two researchers employed a 29-ques-tion rating system across 11 categories to assess each entry. Results: Jurors noted that most entries displayed strong architectural design and graphic skills. Contrarily, the researchers observed that only a few teams undertook a literature review and conducted research like surveys, interviews, and observations. Many entries missed articulating a compelling narrative about the users and how their designs could provide a good user experience. Although the competition didn’t explicitly demand sustainability, its integration is vital, especially considering the pressing climate crisis. Furthermore, one juror expressed concern over many teams’ insufficient program analysis and development efforts. These observations from the jurors resonated with the rating system’s findings. Conclusion: This competition provides insights into the current state of architectural education with a health focus. It underscores potential pathways for pedagogical advancement, setting the stage for nurturing the next generation of architects with essential skills and mindsets to enhance human health.
Jean Gebser’s Aperspectival Consciousness and Modern Architecture
Authors:   Marywood University, Ding Liyang
Published: May 2024

Jean Gebser, a prominent German-Swiss philosopher, introduces a transformative framework that aims to elucidatehuman consciousness and cultural structure, laying the foundation for a new approach to interpreting the developmentof architecture. This paper delves into the intersection of Gebser’s theory and modern architecture, with a particularfocus on the emergence and advancement of the “aperspectival” spatial concept in the work of German architect HansScharoun as an illustrative example.Challenging the prevailing linear understanding of time and space, Gebser’s The Ever-present Origin offers insights intothe forms and mutations of human consciousness from its primordial beginning to the “present,” positing that humanityevolves through different modes of consciousness, with each mode building upon and transcending the previous one.Gebser believes that because a key aspect of understanding human perception of time and space is the notion of perspective, the discovery and application of perspective indicate people’s consequent awareness of space. Therefore, based on the absence or presence of perspective, Gebser recognizes three “epochs” in human history, “unperspectival,” “perspectival,” and “aperspectival,” which correspond to the era from the inception of human civilization to the Renaissance, from the Renaissance to the early 20th century, and from the twentiethcentury onward, respectively.Gebser’s philosophy thus provides a new framework for us to understand architecture. Borrowing Gebser’s analysis ofthe “aperspectival” consciousness, this paper shows that the development of modern architecture during the earlydecades of the twentieth century embraced a new spatial language that was aimed to reconcile the fragmentation ofmodern life and form a harmonious wholeness, resonating with the evolving human awareness of “integrity.” The workof notable architects, such as Frank Lloyd Wright, Walter Gropius, and particularly Hans Scharoun, emphasized theinterpenetration of spaces, the blurring of inside-outside boundaries, and the liberation from the linear perspectival spatial construction. The paper thus explores the profound affinity between Gebser’s concept and Scharoun’s architecture, demonstrating that in his theater and concert hall projects, Scharoun challenged both the linear perspective tradition and linear progression of time. Through a close reading of Scharoun’s spatial creation, this paper argues that the architect experimented with new spatial concepts such as “simultaneity” and “aperspectivity” and designed structures that not only accommodated the changing needs of individuals, programs, and society but also promoted a holistic and integral consciousness.

ABSTRACT
In recent years, the concept of "psychological well-being," encompassing proper functioning and balance in the emotional, psychological, and social aspects, has been recognized as a determining factor in the progress of different societies. The aim of this study focuses on analyzing the significance of mental health and emotional connections among teachers, workers, and administrative staff in Ibero-American university settings. The research method employed was based on an updated bibliographic document review from 2018 to 2023 using databases such as PsycINFO, Medline Plus, EBSCO, Scielo, Psicodoc, PsycArticles, and major institutional postgraduate repositories, obtaining 60 publications, from which 22 scientific articles and doctoral theses were selected. The results identified that technological advancements, population growth in various societies, and the increasing number of enrolled students in higher education have led to heightened levels of stress among individuals working in higher education environments. It is concluded that among the identified phenomena, pressures associated with work and its connection to teaching responsibilities, personal interactions in university settings, organizational structures of higher education institutions, the demand for creativity and proactivity, as well as the continuous focus on academic processes, combined with the lack of interest from some students in learning, are key factors triggering work-related stress in professors, administrative staff, and employees linked to university environments.
Kentsel Akarsu Koridorlarının Yeşil Altyapı Sistemi ile İyileştirilmesi: İzmir-Poligon Deresi Örneği
Authors: Güneş Gölbey Aslı , Tokmak Merve
Published: May 2024

Sanayi devriminden bu yana atık deşarj alanları olarak kullanılan akarsu koridorları, hızlı nüfus artışı nedeniyle kontrolsüz gelişen kentler içerisinde görünmez olmuşlardır. Kentsel akarsu koridorlarının büyük bir çoğunluğu beton kanal içerisine alınmış, üzerleri kapatılmış ve yatakları değiştirilmiştir. Kirlilik ve bahsi geçen işlemler sonucunda, doğal işlevlerinin birçoğunu kaybeden akarsular, uğradıkları baskılar sonucunda sorun kaynağı haline dönüşmüşlerdir. Oysaki, taşkın kontrolü, rekreasyon potansiyeli, biyoçeşitlilik rezerv alanı olma vb. hizmetlerle ekosisteme sağladıkları faydalar nedeniyle kentsel akarsu koridorları iyileştirilerek kente ve ekosisteme yeniden kazandırılması gereken alanlardır. Bu yaklaşımla, yaklaşık 30 yıldan bu yana kentsel akarsu koridorlarına yönelik farkındalık artmış ve koridorların yeniden ekosistemlere entegre edilerek iyileştirme çalışmaları hız kazanmaya başlamıştır. Çalışma alanı olan Poligon Deresi de yoğun kentleşme baskısı altında, beton kanala sıkıştırılmış ve kimi bölgesinde üzeri kapatılmış olarak ekosistemden koparılmış ve can ve mal kaybına yol açan sel baskınlarına neden olan kentsel akarsu sistemidir. Bu çalışma, Poligon Deresi’nin yeşil altyapı yaklaşımıyla yeniden ekosisteme ve kente entegre edilmesini ön gören restoratif ve rehabilitif tasarım önerilerini sunmaktadır. Çalışma iki farklı yaklaşımla yürütülmüştür. Poligon Deresi’nin yaratmış olduğu yıkıcı taşkınların kısa vadede iyileştirilebilmesi için öncelikli olarak mevcut durumun geliştirilmesine yönelik rehabilitasyon projesi hazırlanmış, alanın uzun vadede iyileştirilip doğaya yeniden kazandırılması ihtimaline ve yeni kentsel yerleşim alanlarında bulunan akarsu koridorlarının doğru kullanımlarına örnek oluşturulabilmesi açısından ikinci bir restorasyon projesi önerilmiştir. Restorasyon projesi aynı zamanda kentsel akarsuların yapılaşma baskısı altında kalmadan önce ekolojik prensiplere uygun olarak tasarımına yönelik durumu da içermektedir. Çalışmanın sonucunda, oluşturulan, rehabilitasyon ve restorasyon projeleri mevcut durum ile kıyaslanarak tartışılmış, iyileştirmeye yönelik çeşitli önermelerde bulunulmuştur. Sonuç olarak, sağlıklı bir kent ekosistemi oluşturulabilmesi için, büyük ölçekli plan kararları alınmasından itibaren ekolojik temelli yaklaşımların çok daha iyi sonuç vereceği, yeşil altyapı sistemlerinin desteği ile kentlerin afetlere dirençliliğinin yükseleceği ve mevcut doğal kaynakların daha sürdürülebilir ve verimli kullanılabileceği görülmüştür.

Optical and electrical evaluation methods of plasma-induced damage in InP substrates
Authors: Goya Takahiro , Urabe Keiichiro , Eriguchi Koji
Published: May 2024

Indium phosphide (InP) has been focused on as one of the emerging materials that can be implemented in advanced semiconductor devices. We proposed optical and electrical characterization methods to evaluate plasma-induced physical damage (PPD)—ion bombardment damage—to InP substrates. By introducing a native oxide phase in an interfacial layer, we proposed an optical model of the damaged structure applicable for in-line monitoring by spectroscopic ellipsometry. Gas species dependence was obtained, which suggested that the H2 plasma exposure formed a thicker damaged layer than Ar. Impedance spectroscopy (IS) under various biases (V
b) was implemented to reveal the nature of damaged structures. Capacitive and conductive components assigned by the IS were confirmed to depend on incident species from plasma, indicating the difference in the energy profile of created defects. The presented methods are useful to characterize and control PPD in designing future high-performance InP-based devices.

The application of methods of long-term storage of sugar beet for a period of more than 2 months is justified. It has been found that small root crops are more susceptible to temperature fluctuations and relative humidity of the environment, which leads to a change in the partial pressure of water vapor between the surface of sugar beet and the surrounding air. During storage in a sugar beet mound, the relative humidity reaches from 90 to 95% due to the removal of moisture from the surface of root crops, which is a source of beet mass losses. The criteria for the size of sugar beet root crops have been determined. The necessity of creating a method for sorting trucks at the receiving point of sugar factories is shown. It was revealed that when determining the requirements for sugar beet entering storage, it is necessary to take into account, in addition to physical and chemical parameters, the value of the specific surface area of the root crop. Therefore, it is recommended to send large root crops weighing more than 570 g to kagats. The purpose of the article is formulated, which is to develop software and algorithmic support for determining the parameters of sugar beet root crops when sorting trucks. The process of distribution of trucks at the receiving point of sugar factories by man at the present time is described. A block diagram of the algorithm of the intelligent vision system program is presented and described. The features of the created software are described, such as working with sensors, processing software or hardware errors. According to the results of the study, an algorithm for the operation of the program and software of an intelligent vision system for determining the parameters of sugar beet root crops have been developed [1].

Studies to assess the effect of discrete hardening of the crankshaft journals on its fatigue strength have been carried out. For this purpose, fatigue tests were carried out on two control parts of the D80 type crankshaft. It was established that the destruction of control part No. 1 occurred after 322,000 cycles, control part No. 2 after 201,000 cycles. The destruction zone of both control parts passes along the R8 mm transition fillet of the connecting rod journals. This allows us to conclude that the discrete hardening factor is not associated with fatigue failure of the control parts. In order to determine the service life of the crankshaft of the KamAZ 740 engine, strengthened in a discrete way (shaft of the fourth repair size), it was installed on a KamAZ 5320 vehicle. As a result of the tests, it was found that during the entire testing cycle the vehicle's mileage was 109,000 km. Moreover, at the time of completion of the tests, all parameters of the car’s engine met the technical requirements. The KamAZ 5320 vehicle is in operation to this day. Its mileage was 269,000 km without stopping for major repairs. To conduct operational tests of a cast iron crankshaft with discrete hardening of a D80 type engine, a 1D80B diesel generator engine was taken, which after assembly was subjected to full-scale testing. These tests included a 100-hour engine run-in, determination of the vibration level and amplitudes of torsional vibrations of the diesel generator shaft line in the operating speed range. The analysis of the vibration state of the engine showed that in all test modes the vibration level at the points under study does not exceed the norms (0.350 mm on the turbocharger housing and 0.150 mm on the generator foot). The maximum stresses from torsional vibrations were: 8, about 17.5 MPa; 4, 5 order 10.5 MPa; 1.5 order 10.0 MPa. The resulting stress levels are significantly lower than permissible. Tests of the 1D80B diesel generator showed its full compliance with the technical requirements for the operation of this engine.

The purpose of the research is to substantiate the critical rotation speed of the working body based on force analysis and modeling of the movement of particles of a bulk product in a horizontal loader with radial blades located in a circulation mixer. The research methodology involved substantiating the maximum rotation speed of the loader working body based on an analysis of the forces acting on particles as they move by the loader blades and fall into the tray during flight. Based on the obtained expressions, the values of the indicators were modeled to analyze and substantiate rational values. The implementation of a numerical analysis of the obtained expressions based on force analysis and process modeling with the Mathcad mathematical package made it possible to identify the critical values of the rotation speed of the working body of a paddle loader based on the condition for the possibility of material coming off the blade and the condition for the possibility of particles flying from the blade into the receiving tray. Due to the need for material to flow off the blades and the rotation speed reduction factor of 0.9, the rotation speed of a blade loader with an outer diameter of blades of 0.24 m and an inner diameter of 0.17 m should not exceed 77 min-1 . The highest rotation speed of the working body shaft at which particles of material will enter the receiving tray area from the outer end of the blade is 43 min-1 , and from the inner end - 73 min-1 . In the process of manufacturing a circulating mixer with a radial blade loader for experimental studies, it should be possible to change the rotation speed up to 43 min-1 . To test theoretical principles in exploratory experiments, it is necessary to provide for the possibility of changing the rotation speed of the blade loader shaft to 70 min-1 .

One of the most promising methods for processing agricultural products today is the ozonation process. The effect of ozone on grain will allow it to be disinfected and stimulate the growth processes of the seed, without causing harmful emissions into the environment. The purpose of the research was to find the optimal time for ozonation of grain and seeds depending on the processing speed of a certain volume of grain material. To achieve it, numerical optimization methods were used, namely the patternsearch global search method, which will determine the most rational ozonation regime for given conditions, were used to achieve it. The source of ozone propagation in a grain heap during ozonation for 10...60 minutes is close in shape to an ellipsoid, but has a slightly different mathematical description. The mathematical models obtained by interpolation make it possible to determine the minimum ozonation time and the maximum speed of ozone treatment per unit volume of a grain heap. It was revealed that increasing the processed volume of grain due to the longer duration of the operation does not make sense, as it will contribute to an increase in energy and cost costs. Under given conditions, an ozonation time of 1270 seconds provides a maximum ozone treatment rate of 3059 mm3/s per unit volume of grain. Optimization will make it possible to ozone the maximum volume of a grain storage facility as quickly as possible at minimal cost. The shortest processing time per unit volume under these conditions was 0.000327 s/mm3. Other ozonation parameters will have different optimal values, therefore the proposed methodology is the basis of an appropriate computer program that will automatically determine the optimal ozonation regime for specific conditions.

The current problem of operating automotive equipment at low temperatures associated with the loss of diesel fuel’s properties (reducing the cloud point and crystallization of the fuel) is being considered, resulting in equipment failures due to failure of the power system and direct freezing of the fuel in the tubes, paraffin deposition leading to clogging of fuel filters. Domestic automotive vehicles do not have any effective means of heating diesel fuel, which forces drivers operating equipment in harsh climatic conditions to use their own individual developments. For these purposes, a device has been developed that allows you to heat all the diesel fuel poured into the fuel tank. The drive of the device (fuel priming pump) is proposed to be electric (from a linear electric motor), from the vehicle's on-board network, the type of pump used is piston, double-acting. A comprehensive calculation of the fuel priming pump is presented in order to determine its main characteristics and design dimensions. A schematic diagram of the installation of the developed device and all elements in the diesel engine power system is presented. The implementation of the proposed technical solution was carried out in the power system of the YaMZ-238 diesel engine installed on a load stand under conditions of its operation in low temperatures (the Far North, etc.). The obtained results of tests on a bench engine confirm the relevance of the research and showed that the use of the developed technical solution will allow heating all the diesel fuel poured into the car tank to a temperature of plus 50 °C, thereby eliminating the possibility of its crystallization and cloudiness and, in general, reducing the number of vehicle failures. techniques related to this problem.
