Spatial Pressure: The Manipulation of Fluid Space through the Hybridization of Art and Architecture
Authors:   , Prins Anneke
Published: November 2021

I believe that although those trained within the discipline of architecture are skilled at sculpting form and space, art practice is often more successful at manipulating spatial conditions beyond architectural norms to affect the dynamic human body. This research thesis proposes that by employing an art practice methodology to influence the architectural design process then a new type of spatially affective, hybridized architecture might be created.  In affect theory, knowledge of the body’s interaction with space and other bodies, and reaction to atmosphere is essential to the understanding of a spatial environment. Knowledge of the body and of spatial relationships are inherent to the architectural discipline and yet art practice is often more successful at challenging and manipulating affective responses. While architecture promotes affective responses from those who inhabit, or move through, built forms, might we employ art practice to enhance these spatial reactions?  Spatial Pressure proposes that if the architectural discipline employs sculptural art practice methodology then a new type of successful spatially affective architecture might be created. It also proposes that through the manipulation of fluid space, hybrids of art and architecture can affect the dynamic body and enhance spatial responses.  The thesis argues for the development of new modes, methods and markers of creating and analysing affective hybrids in order to manipulate spatial reactions. It argues for a reintegration of the body into architecture through the central method of the creation of human scale, sculptural yet pragmatic, interventions. In this work the observation of the body’s response to these interventions is analysed and reinterpreted with each design move, avoiding direct representation of the body.  By employing sculptural practices to create publically activated, art-architecture, the hybridized interventions act to push and pull space and encourage movement through spatial pressure. The body moves, the spatial interventions are static; it is the “in-between” that provides the affective condition.  Working in a liminal zone between two disciplines creates challenges and opportunities to enhance affective influences and opens the possibility of altering current norms of architectural practice.
Curation
Authors:   , McEwan Zachary
Published: November 2021

Today we see a simplification in our landscapes; a globalisation of culture and landscape that has forced people into a state of disconnection with place. It has divided our world into culturally rich, and culturally absent worlds. Worlds where natural ecologies are seen as separate entities to the human cultures that live on the land. Our landscapes need to reconnect and adapt; not only to the ever increasingly culturally diverse world, but also to the site specific social and natural ecologies that exist.  Wainuiomata is no exemption to this condition. Its suburban landscape is divided from the natural ecologies that lay dormant on its peripheries. It is an austere environment, but one with a colourful and culturally diverse community that is unable to express itself.  This piece of research argues that landscape architecture has the ability to enable disadvantaged communities to rekindle a sense of connection with, and custodianship over their landscapes. It discusses ways of designing that can reform lost relationships between communities and the common ground they live upon.  The work brings forward how landscapes can be designed in ways that provide opportunities not only for communities to self build their landscape, but also how the architect can create frameworks that facilitate a process of engagement at different scales. It further explores how a respect for ecological environments can be instilled into the community through building relationships between ecological and social environments, as opposed to their current segregation.  Lastly, the thesis looks at how a landscape architect may design in a way that pushes beyond the final drawings. Doing this with an understanding that it is a curation of a process (one where communities can become a part of the making of a landscape) that will bring a sense of custodianship to its dwellers.
Towards a Connected Commons: Two case studies examining New Zealand collecting domain establishing Open GLAM practices for digital collections
Authors:   , Powell Sarah
Published: November 2021

As pressure grows for cultural institutions to provide online access to images of collection objects, issues regarding copyright and reuse of materials arise. Yet little research has been conducted on the way heritage institutions within New Zealand have tackled these copyright issues and how they reach decisions to allow the reuse of digital content from their extensive online collections. Furthermore, there is a lack of academic investigation into what value any newly introduced reuse practices and policies can bring to cultural institutions and users of their digital content. My research explores how and why New Zealand’s two collecting domains, the National Library of New Zealand and the Museum of New Zealand Te Papa Tongarewa, provide openly licensed digital images of artefacts through online collection databases.  While literature on the topic of reuse of digitised documentary heritage collections is limited, previous research shows that there are myriad barriers surrounding the reuse of digitised collection objects, some of these include finding best practice for orphan works, acknowledging indigenous sensitivities, dealing with issues of trust and balancing commercial imperatives with public expectations. The body of literature also shows the opportunities and benefits that international cultural institutions have gained from establishing reuse practices for their digital collections, yet none offer insight from a New Zealand context.  Guided by this gap within the literature this dissertation investigates the establishment of use and reuse policies and practices by the National Library of New Zealand and the Museum of New Zealand Te Papa Tongarewa, and what value they feel this practice may bring to the sector. It explores each respective institution’s journey towards a connected commons through two in-depth qualitative case studies and concludes with a cross-case analysis. Within the cross-case analysis an Open GLAM Licensing Framework is proposed for Aotearoa that draws on the work that these institutions, along with other leading cultural institutions, have done in establishing reuse practices and policies for digital collections. This research contributes to Museum and Heritage Studies discourse by providing a snapshot of reuse in a New Zealand context and provides a valuable framework to evaluate the current motivations and processes of institutions establishing Open GLAM philosophies.
Exploring the Educational Value of Mathematical Beauty and Effective Ways of Discovering Mathematical Beauty
Authors: Wang Cunrong
Published: November 2021

The precision of mathematical reasoning, the abstractness of mathematical language, the profundity of mathematical thought and method, as well as the excessive formalization of mathematics teaching have formed an impassable gap, hindering students in approaching mathematics. This has concealed the beauty of mathematics and the light of mathematical culture. However, if students are able to cross this gap, they would find that mathematics is a vast world full of vitality, imagination, wisdom, poetry, and beauty. The pursuit of mathematical beauty is one of the motivations for scientists to research this field. Experiencing mathematical beauty is of great significance to students’ learning and growth. In teaching, the value of mathematical beauty is explored, such as stimulating emotions, opening up to the truth, and cultivating goodness. Several effective ways are suggested in this article to guide students to discover the mathematical beauty in life while finding it in problem-solving methods and exploring it in knowledge systems.

Published: November 2021

Adolescence is the golden stage for developing reading ability. Reading ability is an important factor in promoting teenagers’ know-how and cognitive structure. For teenagers who are at the stage of forming views on the world, life, and values, reading is a key part of understanding the external world. This study is an empirical analysis conducted on 210 teenagers through questionnaires to explore the influence of perceived value of social reading on teenagers’ reading ability by using the structural equation model. The results show that first, the perceived value of social reading affects teenagers’ reading ability; second, social reading motivation is the mediator of the above relationship; third, the perceived value of social reading affects teenagers’ reading ability through reading motivation. In regard to that, it is proposed that the characteristics of perceived value should be made use to stimulate students’ learning motivation and improve teenagers’ reading ability in the process of policy formulation of governmental departments and the teaching in schools.

Anadolu Ağızlarında “Gülmek” ve “Ağlamak” Eylemlerinin Troponimleri
Authors: AKYILDIZ AY Didem
Published: November 2021

WordNet, bir grup psikodilbilimci tarafından tasarlanan ve İngilizce sözcüklerin biçimlerinden ziyade anlamsal ilişkilerine odaklanan oldukça kapsamlı bir veri tabanı projesidir. Bu projede, isimler arasındaki üst anlamlılık-alt anlamlılık ilişkisi, fiiller için de denenmiş ve fiiller için troponimi adında, isimler arasındaki alt anlamlılık ilişkisinden birtakım farklılıklara sahip olan hiyerarşik sözcük ağı ilişkisi kurulmuştur. Bu bağlamda troponimi, fiiller arasındaki anlamsal ilişkilerden biri olup bu ilişki genel bir kavramı ifade eden bir fiilin tarzıyla ilgili çeşitli ayrıntılarını ifade eden başka bir fiille veya fiillerle olan ilişkisi şeklinde yorumlanabilir.

Fiillerde kılınış kategorisi, fiil kökünün bildirdiği temel anlama bağlı başlama, sürme, bitme, tekrarlama vb. bir süreç türünü ifade etmektedir. Standart Türkçede birçok fiil kılınıştaki bu süreçlerin dışında temel anlamında yer alan daha başka tarzlarını ifade etmek için çoklukla söz diziminde belirteç niteleyicileri ile desteklenmektedir. Örneğin “konuşmak” eyleminin (action) fısıldayarak konuşmak, bağırarak konuşmak, hızlı konuşmak, kekeleyerek konuşmak gibi farklı tarzlarını belirtmek için “konuş-“ fiili (verb) bağımsız sözlük birimlerle anlamsal yönden desteklenmektedir. Anadolu ağızlarında ise, bir eylemin kılınış tarzını belirtme doğrultusunda dil dışı gönderge ile dilsel göstergeler arasındaki daha yakın ilişkiler kuran yansıma sözcüklerden oldukça fazla yararlanıldığı tespit edilmiştir. Bu çalışmada Anadolu ağızlarında “ağlamak” ve “gülmek” eylemlerinin çeşitli kılınış tarzlarıyla ilgili ayrıntı bilgilerin standart Türkçedeki gibi belirteçlerle desteklenmeye gerek duyulmadan ifade edildiği ve büyük bir kısmının yansıma sözcüklerden oluştuğu anlaşılan troponimleri üzerinde durulacaktır.

The present work has been characterized by higher order modes in the cavities of the Gyrotron; they are capable of producing RF plasma by developments of it. It uses for fusion systems. We choose the TE31,8 mode in our study. The main problem of gyrotron is the device of the thermal cavity loading. The problem of the thermal loading is solved when any parasitic modes suppress, absence of desired modes; the thermal loading is increased when the high power tube of gyrotron operation is unstable. The mathematical interaction model contains equations that describe the electron motion and the field profiles of the transferred electric modes of the resonator, these are interacting with electrons based on the finite difference method that has been designed to study the starting current, the frequency, quality factor and calculates the roots of the Bessel function by the program we designed in Fortran language. They are used to calculate the operation frequency. Good agreement is between our results and the previous published results both confirm the accuracy of the performance of the designed program.

Authors: Khaesarani Inayah Rizki
Published: November 2021

The inability of students to master the material concept of the advanced differential equation gives rise to internal and external factors that are formed in them so that it needs to require encouragement as effective use of learning media so that learning in the classroom becomes increasingly attractive to students. We used online learning media as zoom, offline or online learning videos, E-learning, and others. This research aimed to identify and describe students learning difficulties in advanced differential equation courses in terms of the use of learning media during the Covid-19 pandemic. The type of research used is qualitative research, with a descriptive approach. Results showed that students have great difficulty learning numerical methods to solve first-order differential equations from all three sub-chapters of matter. In this material, students are still less careful in answering questions (58,1%). Because students could not identify the type of methods used to solve problems, students need online learning media that are effective for math learning, such as offline learning videos (71%), as a solution to save internet quotas. So, this research is useful for educators/lecturers in observing the condition of student learning difficulties given the use of learning media used to motivate students to be active in learning advanced differential equation courses during the Covid-19 pandemic.

Peningkatan produktivitas pertanian padi dan cabai di Desa Langsat Permai meningkat setelah permasalahan ketidaktersediaan air untuk menunjang kegiatan pertanian teratasi. Melalui kegiatan PPDM tahun 2017-2019 yaitu pembangunan canal blocking, terjadi peningkatan produktivitas pertanian terutama tanaman padi (pada tahun 2018 mencapai 7-8 ton/Ha) dan cabai (pada tahun 2018 mencapai 14-15 ton/Ha). Selain pembuatan canal blocking untuk tata air, kegiatan PPDM tersebut juga mengembangkan kegiatan peternakan melalui pembangunan rumah kompos dan pemberian sapi beserta kandangnya. Akan tetapi, pembangunan rumah kompos dan pengadaan sapi tersebut belum optimal dalam upaya mengurangi penggunaan pupuk anorganik. Selain itu, penggunaan pestisida kimia secara berlebihan menyebabkan tingginya biaya produksi yang harus dikeluarkan oleh petani setempat dan berbahaya bagi lingkungan. Berdasarkan permasalahan tersebut, tujuan kegiatan pengabdian ini adalah melakukan pendampingan petani dalam pengembangan sistem pertanian Low External Input Sustainable Agriculture (LEISA) dalam pengelolaan pupuk maupun pengendalian hama penyakit tanaman yang dibudidaya oleh petani setempat. Pendampingan petani dilakukan dengan pembuatan demonstrasi plot pada lahan pertanian desa setempat. Dari hasil demplot yang dilakukan pada tanaman padi, cabai, dan jagung terlihat bahwa penggunaan pupuk anorganik dapat dikurangi sebanyak 25% untuk mendapatkan pertumbuhan dan hasil lebih baik, sedangkan penggunaan agens hayati lebih disarankan dibandingkan pestisida nabati untuk mengendalikan serangan hama di lahan pertanian petani Desa Langsat Permai.

CHD is chest pain or discomfort that occurs if the area of the heart muscle does not get enough oxygen-rich blood. CHD is also known as coronary artery disease. CHD is increasing every year with a significant number of deaths. A learning algorithm is proposed to get better performance in accuracy, sensitivity, and specificity in CHD interpretation. Accuracy can be improved by adding a Kaiming He (2015) weight initialization optimization technique to the DNN structure. Therefore we propose that DNN is optimized with a Kaiming He weight initialization technique so that it can overcome weaknesses in the data variant. This is evidenced by the results of the accuracy performance of 98.73%. Initialization of kaiming he weights is proven to improve accuracy and overcome the problem of large data variants between classes

Activities suitable for planting with hydroponic systems in the midst of covid 19 pendemi are in great demand by utilizing limited land. One of the elements in suitable planting activities is water, because 70 percent of the molecules in plants are water. Water serves as the raw material of plants in the process of photosynthesis and can also keep plant moisture from withering. Currently the method of watering plants is still done manually by checking the condition of the soil, if the soil condition is dry then the new water pump is turned on for watering. But the method is considered less effective because it requires farmers to do regular checks and should not forget so that the soil does not dry so that the plants do not wither. To answer these problems in this study want to provide certainty how the plant gets enough water. One of the efforts that can be done is to make an automatic watering tool that without having to take time so as to give an efficient impact. The tool is made using Arduino Mega 2560 Components that serve as controllers in the watering system with the help of smartphones for remote control.

Predicting disease is usually done based on the experience and knowledge of the doctor. Diagnosis of such a disease is traditionally less effective. The development of medical diagnosis based on machine learning in terms of disease prediction provides a more accurate diagnosis than the traditional way. In terms of predicting disease can use artificial neural networks. The artificial neural network consists of various algorithms, one of which is the Backpropagation Algorithm. In this paper it is proposed that disease prediction systems use the Backpropagation algorithm. Backpropagation algorithms are often used in disease prediction, but the Backpropagation algorithm has a slight drawback that tends to take a long time in obtaining optimum accuracy values. Therefore, a combination of algorithms can overcome the shortcomings of the Backpropagation algorithm by using the success of the Gravitational Search Algorithm (GSA) algorithm, which can overcome the slow convergence and local minimum problems contained in the Backpropagation algorithm. So the authors propose to combine the Backpropagation algorithm using the Gravitational Search Algorithm (GSA) in hopes of improving accuracy results better than using only the Backpropagation algorithm. The results resulted in a higher level of accuracy with the same number of iterations than using Backpropagation only. Can be seen in the first trial of breast cancer data with parameters namely hidden layer 5, learning rate of 2 and iteration as much as 5000 resulting in accuracy of 99.3 % with error 0.7% on Backpropagation Algorithm, while in combination BP & GSA got accuracy of 99.68 % with error of 0.32%.

Strengthening on Micro, Small and Medium Enterprises (MSMEs) in Indonesia needs to be supported by the use and good information systems management. Therefore, business actors are expected to be able to use a operational strategy supported by the use of information systems. Workshop is one of the complex MSMEs with integrated warehousing and financial reporting. The problem faced at this workshop UMKM is that there is no synchronization between the existing stock of goods and the sales stock, as well as reporting both warehouse reporting and financial reporting. For this reason, this study aims to build a web-based MSME information system for tire & rims workshops. In building this system, researchers used the agile software development method, namely SCRUM. This method is used because the system can adjust to the needs of the product owner, which is always changing and fast in processing. The results of this scrum stage, namely the product log, sprint backlog, sprint and working increment of the software, can resolve all problems that occur with regard to time, scope and cost issues so that in the implementation of making this system application can reduce the system requirements gap during the sprint process. So that the system can be completed in accordance with the requirements needed by the user. By using this workshop's UMKM information system, all sales operational activities can be monitored properly and sales and financial reports can be well structured.

In the era of the industrial revolution 4.0 as it is today, where the internet is a necessity for people to live their daily lives. The high intensity of internet use in the community, it causes the distribution of information in it to spread widely and quickly. The rapid distribution of information on the internet is also in line with the growing growth of digital data, so that the public opinions contained therein become important things. Because, from this digital data, it can be processed with sentiment analysis in order to obtain useful information about issues that are developing in the community or to find out public opinion on a company's product. The number of studies related to sentiment analysis that applies the Naive Bayes algorithm to solve the problem, so researchers are interested in conducting research on the use of feature selection for the algorithm. Therefore, this research was conducted to determine what feature selection is the most optimal when combined with the Naive Bayes algorithm using the Systematic Literature Review (SLR) research method. The results of this study concluded that the most optimal feature selection method when combined with the Naive Bayes algorithm is the Particle Swarm Optimization (PSO) method with an average accuracy value of 89.08%.

There have been many studies on online essay exams but the scope of the discussion is for automatic correction or similarity based on text input. In vocational education, especially PTKI Medan, which has a test that is not limited to text input but there are calculations. Another weakness of text input is that the answers can be more easily copied and pasted by students. This research was carried out for 1 year starting from Odd semester 2020 to Even 2020. The method in developing information systems uses the waterfall model with the stages of needs analysis, system design, coding, implementation and the last stage of system maintenance. From the results of the research in the odd semester of 2020, the researchers used a text-based online essay exam model, but many weaknesses were found, one of which was the ease of students in using answers from the internet which were directly entered into the answer column. At the maintenance stage, the researcher updates the system by changing the image-based exam model, so students must write their answers on paper and then upload the answers to the website. The file upload system can overload the server if it is not controlled, one of the techniques used is to compress image files uploaded by students to the system and the maximum size can be compressed up to 78.48% from 1329 Kb to 286 Kb for this type. png data. In addition, to make it easier for lecturers to check answers, use the ezoom.js feature as a means to view answers in the form of images that are useful for zooming in, zooming out, rotating the answer images. Ezoom.js is a javascript that can be installed on php-based websites
