Published: June 2023

Parkir merupakan bagian yang sangat penting dalam manajemen lalu lintas terutama di kawasan perkotaan. Seperti di kawasan Jalan Permindo yang merupakan jalur perlintasan Pasar Raya Padang dan juga merupakan pusat perbelanjaan di Kota Padang. Sehingga menimbulkan kurangnya ketersediaan ruang parkir pada kawasan tersebut, di mana tempat-tempat yang biasanya bukan merupakan tempat parkir pun menjadi lahan parkir dikarenakan tempat parkir yang sudah penuh. Oleh karena itu diperlukan perencanaan ruang parkir yang baik di area perkotaan. Penelitian ini bertujuan untuk mengetahui ketersediaan ruang parkir, jumlah kendaraan yang parkir dan pemanfaatan ruang parkir di jalan Permindo. Metode penelitian yang dilakukan dalam penelitian ini adalah menggunakan data Primer dan Sekunder, yang disurvei secara visual. Berdasarkan hasil penelitian, didapatkan nilai akumulasi parkir mobil di jalan Permindo terbesar yaitu sebanyak 650 kendaraan, untuk persentase penggunaan ruang parkir kendaraan roda empat di jalan Permindo pada hari Sabtu dan Minggu melebihi 100%, sedangkan untuk kendaraan roda dua akumulasi parkir terbesar yaitu sebanyak 641 kendaraan, untuk persentase penggunaan ruang parkir kendaraan roda dua di jalan Permindo pada hari Senin sampai Minggu melebihi 100%. Sebaiknya untuk mendapatkan kapasitas parkir yang dibutuhkan untuk kendaraan mobil bisa diparkirkan di gedung parkir atau dirubah posisi parkir menjadi 90º, sedangkan untuk sepeda motor juga bisa diarahkan ke gedung parkir.Kata kunci :Parkir, ruang parkir, optimalisasi

The New Northern Ireland as a Crime Scene
Authors: Brunsdon Charlotte
Published: June 2023

This article explores the increased attractiveness of a ‘post-conflict’ Belfast as a television setting for British television police series. The Fall (2013, 2016), Bloodlands (2021) and Marcella (2021) are all set in Belfast, while most of the hit series Line of Duty (2012–) has been filmed in Northern Ireland. How do these new Belfast-set crime dramas negotiate the tropes and iconography of twentieth-century Troubles Belfast, while also participating in the transformation of the city associated with the arrival of transnational audiovisual industries? While recognising that much recent scholarship focuses on the creation of the Titanic Quarter through the redevelopment of the Harland & Wolff shipyard and the production of the HBO-Warner series, Game of Thrones, this article pursues the recent appearances of contemporary Belfast on screen in Bloodlands, Marcella (2021) and Line of Duty. Building on scholarship, such as the work of John Hill, Martin McLoone and Ruth Barton which has established the contours of the Troubles film, the history of Belfast on film and genre in the Northern Ireland context, the existence of an identifiable chronotope ‘Troubles Belfast’ is proposed. Is Belfast recognisable as a specific place outside a Troubles chronotope? What are the stories that can be told of Northern Ireland outside a Troubles chronotope? In particular, which is pertinent to an industry desperate to maintain its attractiveness to transnational productions, the tension between the identification of Belfast as a specific place and the generation of new and different stories is explored in the case studies. To what extent is the televisual use of the new screen Belfast caught in the paradox that it is the old Belfast which makes it an attractive setting for crime drama?
Carnophallogocentrism and Eco-Deconstruction
Authors: Fritsch Matthias
Published: June 2023

Whether deconstruction is relevant to environmental philosophy, and if so, in what ways and with what transformations, has been subject to considerable debate in recent years. I will begin by discussing some reservations regarding deconstruction’s relevance to environmental thought, and argue that they stem from an older misreading of Derrida’s work in particular as hostile to the natural sciences, and as a cultural textualism of relevance only to the interiority of a traditional canon, but unable to reach the materiality of the outside environment. This attempt at refutation will permit a better understanding of the deconstructive argument for what has been called an ‘originary environmentality’ of life. On this basis, I seek to argue that deconstruction tends to be most promising to environmental questions when it shows responses to the call, not primarily for a new ethics, but for far-ranging analyses of our conception of politics. The reason for this lies in the overall deconstructive goal of exposing political and legal sovereignty, including its modern democratic understanding, to what I will elaborate as contextual or environmental finitude.
Using Coral Color to Indicate Coral Health in Five Caribbean Species

Published: June 2023

Coral reefs are one of the most biodiverse and productive ecosystems on Earth, and color has been shown to indicate coral health in Australian and Hawaiian reef systems. However, no standardized method exists to quantify coral health for Caribbean corals. Therefore, a health assessment card using coral color was developed for five species of Caribbean corals to monitor coral health non-invasively. To quantify coral health, individual corals of each species were photographed in a controlled environment to develop color profiles. Simultaneously, nondestructive measurements of “health” were quantified by measuring photosynthetic efficiency (Fv/Fm) using pulse amplitude modulation (PAM) fluorometry, which determines how efficiently the symbiotic algae provides energy to the coral host. The results of this work successfully corresponded photosynthetic efficiency to coral color for five dominant species of Caribbean corals to develop a Coral Health Assessment Card for Caribbean reefs. Implementing a standardized assessment of symbiont performance can assist in monitoring changes in coral health, which can consequently be implemented into long-term and widespread monitoring projects to track overall Caribbean reef health.

Implementation of Artificial Intelligence Technologies for Ensuring National Security and Defense Capability of Ukraine: Legal Issues and Prospects for the Post-War Period
Authors: Patsuriіa Nino
Published: June 2023

The article discusses the problems and prospects of implementing modern information and communication technologies, including artificial intelligence, in the sphere of ensuring national security and defense capability of Ukraine. The main regulatory acts that contain provisions on the introduction of artificial intelligence in the defense and security legislationof Ukraine are investigated, as well as the negative and positive aspects of introducing artificial intelligence and the European and global experience of using artificial intelligence in this direction. The issue of transferring artificial intelligence technologies through the security and defense sector to other sectors of the economy is also raised. Ensuring national security and defense capability of Ukraine in the post-war period should become the main priority of the country's military and political leadership.It is argued that the rapid, efficient, and flexible provision of society's needs for military security and defense of the state in the post-war period can be achieved through the introduction of advanced technologies, including the use of artificial intelligence and Big Data, as a priority for the further development of the defense industry complex of post-war Ukraine. Today, artificial intelligence belongs to such technological areas of social development that are rapidly evolving and have great potential in many fields, including national security, defense, military medicine, military logistics, intelligence and counterintelligence, aerial reconnaissance, and so on. This explains the essence of the chosen problematic, its relevance, and the need for its research.It is concluded that the use of artificial intelligence in the sphere of ensuring national security and defense capability of Ukraine can have both positive and negative aspects. As a generalization, it is noted that in order to ensure national security and defense capability of Ukraine in the post-war period, it is necessary to develop and introduce the best world practices into national legislation, taking into account the potential opportunities and threats of artificial intelligence, and ensuring the transfer of artificial intelligence technologies through the defense and security sectors to other sectors of the economy.

The Setipinna breviceps is a commercially important and highly esteemed food fish. This species has scant of scientific formation particularly on population parameters like growth, mortality and recruitment. The present study aimed to estimate the body indices and population parameters of Setipinna breviceps of Batang Lassa Estuary (BLE). Samples were collected between April 2019 and September 2020. A local made bag net known as Gnian (mesh size 1.25 to 4.00 cm) was used for sampling the fish. A total of 287 qualified specimens were used for this study. The length and weight of individual fish was measured to the nearest 0.1 cm and 0.01 g, respectively. The length ranged from 5.50 to 24.00 cm and growth coefficient (b) was 2.563 (R2 = 0.87) which clearly indicated a negative allometric growth. About 50% of individuals showed flat or slender body (Kn<1) and 47% of the specimens were rounded shaped (Kn>1) while 2.44% of fishes measured an ideal shape (Kn = 1). The parameters of growth L∞, K and ϕ’ were estimated at 24.15 cm, 0.23 yr-2 and 2.13, respectively. The estimated natural mortality and fishing mortality were 0.74 and 0.29 yr-2, respectively and exploitation rate was 0.28. The recruitment pattern during the study was observed at two possible unequal peaks. The present study concluded that the anchovy was under exploited (E<0.5) as demonstrated by the under-sized fishes caught with small mesh size net. However, considering the minimum lengths and length at first catch, the BLE could be a productive nursery ground for S. breviceps. Therefore, management actions are required to avoid juvenile catches.

In the studies and production of bioethanol, the preferred fermenting yeast (Saccharomyces cerevisiae) is usually cultured in liquid broth that contains yeast extract and peptone. However, the use of these laboratory and scientific grade chemicals is costly, making them impractical for mass bioethanol production. Therefore, this study was conducted to evaluate the feasibility of glucose ethanolic fermentation by S. cerevisiae using generic fertiliser formulations to provide inorganic nitrogen, phosphorus, potassium and trace elements (NPK-TE). Fermentation media of different generic fertiliser strength at 0.5X, 1.0X and 2.0X Fertiliser Nitrogen Equivalents (FNE), as compared to the conventional Yeast Extract-Peptone (YEP) medium as control, was used as fermentation broth during the ethanolic fermentation of glucose. Based on the results, S. cerevisiae cultured in YEP broth produced the highest cell concentration for both wet (21.93 g/L) and dry cells (3.87 g/L), with rapid increment observed in the first 72 h of fermentation. By the end of the fermentation period, lactic acid (3.14 g/L) and acetic acid (0.96 g/L) levels were recorded to be the lowest in YEP medium while their concentration (lactic acid, 8.08 g/L) and (acetic acid, 2.67 g/L) were highest in 2.0X FNE fertiliser medium. Results indicated that the best theoretical ethanol yield (TEY) among the fertiliser media was achieved when fermentation was performed in the 0.5X FNE fertiliser medium, with a TEY of 86.18%. TEY yields were 78.68% and 51.54% in broth with 1.0X and 2.0X FNE, respectively. In general, all three fertiliser media supported ethanolic fermentation of glucose, with the 0.5X FNE fertiliser broth showing a yield that is significantly close to the conventional YEP medium, as seen in the statistical analysis. Similarities in other fermentation profiles such as acetic acid, lactic acid, and biomass production, as well as glucose utilisation, between the results from the YEP samples and samples from the fertiliser broths (at 0.5X and 1.0X FNE) have also shown that generic fertiliser has the potential to be used as an alternative medium to replace the conventional YEP to produce ethanol at a lower cost.

Published: June 2023

Chrysanthemum sp. is a floricultural plant of the Asteraceae family with high economic value. The anthocyanin pigment in red chrysanthemum acts as an antioxidant, the content of which can be influenced by genetic factors such as the physiological age of the flower. This study aimed to determine the effect of flower age on anthocyanin content and antioxidant activity in red chrysanthemum plants. The age of red chrysanthemum used was 115 Days After Planting (DAP) (early bloom stage), 120 DAP (half-bloom stage), 125 DAP (blooming stage), and 134 DAP (wilted flower). The anthocyanin content was analysed using spectrophotometric methods. Antioxidant activity was determined by the DPPH method and then the absorbance was measured using a UV-Vis spectrophotometer. The results showed that the highest anthocyanin content was obtained at the age of 134 DAP at 3.56 mg/g, followed by the age of 115 DAP at 2.40 mg/g, then at 125 DAP at 1.95 mg/g and the lowest at 120 DAP at 1, 69 mg/g. The highest antioxidant activity was shown in chrysanthemum flowers aged 115 DAP which had an IC50 value of 288.85 g/ml. The research shows that wilted chrysanthemum flowers still contain anthocyanins so it can be used in various industrial fields such as chrysanthemum tea and additives for soap.

Authors: Yikeng Liang , Bin Zamani Mohd Fairuz
Published: June 2023

Incorporating Yunnan Yi music elements into piano compositions is a growing trend in Chinese piano music, and Yi piano adaptations serve as an important representation of Yunnan piano music’s ethnic style and development. However, a lack of systematic investigation and observation means that little research has been done on the composition of Yi piano adaptations. This presents a challenge for aspiring piano students looking to interpret the Yi characteristics of these works. This study aims to provide a systematic discourse on prior research and investigate the relevance and contribution of Yi piano adaptations in reducing the existing gap. Literary research and musical analysis will be employed to analyze the Sani Fantasia adaptation. A literature analysis will classify relevant piano adaptation works and appreciate Yi piano music’s overall growth pattern, while a systematic examination of Sani Fantasia will reveal how Yi’s music elements are expressed and translated in the piano pieces while maintaining the original folk song’s ethnic style. The researchers hope the study will deepen academics’ understanding of the cultural significance and worth of Yi piano adaptations and piano compositions in the Yunnan ethnic styles.

ABSTRAK

 

Bahasa Remun sering menarik minat pengkaji untuk meneliti aspek bahasanya kerana ciri linguistiknya yang agak berbeza daripada dialek-dialek Iban lain di Sarawak.  Malah, ada pengkaji beranggapan varian Iban Remun ini berstatus “bahasa tersendiri” dan tidak menganggapnya sebagai dialek bahasa Iban. Justeru, kajian ini bertujuan untuk menentukan tahap hubungan kekerabatan di antara bahasa Remun dengan varian Iban lain di Sarawak khususnya bahasa Iban Undop. Selain kaedah leksikostatistik iaitu perbandingan kosa kata asas bagi menentukan peratusan kognat di antara kedua-dua varian ini, kajian ini juga membuat perbandingan kosa kata tambahan dan ciri fonologi.  Hasil kajian mendapati tahap peratusan kata berkognat di antara varian-varian ini ialah 94.7%. Ini bermakna bahasa Iban Remun dan Iban Undop mempunyai hubungan dialektal. Data kajian turut menunjukkan banyak persamaan dari segi inventori fonem dan lingkungan kehadiran fonem dalam kata.  Berdasarkan perbandingan kosa kata tambahan pula, didapati banyak perbezaan di antara varian-varian ini yang boleh menjejaskan kesalingfahaman di antara penutur mereka. Kajian ini juga menyarankan perlu dijalankan kajian susulan yang menyelusuri sejarah penyebaran dialek bahasa Iban di Sarawak serta perbandingan lebih terperinci bahasa Remun dengan varian Ibanik di Kalimantan.

Training is one of the most important human resource development activities in growing industries, especially the manufacturing industry. Preparing learning materials and tracking trainees' performance during a training session are the challenges faced by a local automobile manufacturing company. This project aims to develop a web-based E-learning management system for training purposes at a local automobile company. This online system will complement the traditional method for trainers in preparing learning materials and tracking trainees’ performance. In addition, this system supports in-class activities for trainees to learn and understand, explore, and exchange ideas outside the classroom, while trainers can manage and upload course materials. In order to evaluate the user acceptance towards the system, several tests were conducted. It is envisaged that the proposed system will provide a more convenient way for a local automobile company to train their trainees.
Riemann Hypothesis on Grönwall's Function
Authors: Vega Frank
Published: June 2023

Grönwall's function $G$ is defined for all natural numbers $n>1$ by $G(n)=\frac{\sigma(n)}{n \cdot \log \log n}$ where $\sigma(n)$ is the sum of the divisors of $n$ and $\log$ is the natural logarithm. We require the properties of extremely abundant numbers, that is to say left to right maxima of $n \mapsto G(n)$. We also use the colossally abundant and hyper abundant numbers. There are several statements equivalent to the famous Riemann hypothesis. We state that the Riemann hypothesis is true if and only if there exist infinitely many pairs $(N,N')$ of consecutive colossally abundant numbers $N< N'$ such that $G(N)< G(N')$. Using this new criterion, we prove that the Riemann hypothesis is true.

In the early childhood population, congenital airway conditions like bronchomalacia (BM) can pose a life-threatening threat. A breakthrough technology called additive manufacturing, or 3D printing, makes it feasible to create a biomedical device that aids in the treatment of airway obstruction. This article describes how a polycaprolactone (PCL) splint for the upper airways can be created using the fusion deposition technique (FDM) and sterilized using gamma radiation. It is presented as a simple, accessible, and cost-reduced alternative that complements other techniques using more expensive and sophisticated printing methods. Thermomechanical and morphological analysis proved that FDM and sterilizing by gamma irradiation are both appropriate methods for producing splints to treat life-threatening airway blockages. Additionally, the 3D-printed splints’ effectiveness in treating a young patient with BM that was life-threatening was assessed by medical professionals. In this regard, the case report of a patient with 34 months of follow-up is presented. Splints manufactured by this affordable 3D printing method successfully surpass breathing arrest in life-threatening airway obstruction in pediatric patients. The success of this procedure represents a fundamental contribution to the treatment of the population in countries where access to expensive and complex technologies is not available.

Introduction: The benefits of patient’s specific cell/gene therapy have been reported in relation to numerous genetic related disorders including osteogenesis imperfecta (OI). In osteogenesis imperfecta particularly also a drug therapy based on the administration of bisphosphonates partially helped to ease the symptoms.

Methods: In this controlled trial, fibroblasts derived from patient diagnosed with OI type II have been successfully reprogrammed into induced Pluripotent Stem cells (iPSCs) using Yamanaka factors. Those cells were subjected to repair mutations found in the COL1A1 gene using homologous recombination (HR) approach facilitated with star polymer (STAR) as a carrier of the genetic material.

Results: Delivery of the correct linear DNA fragment to the osteogenesis imperfecta patient’s cells resulted in the repair of the DNA mutation with an 84% success rate. IPSCs showed 87% viability after STAR treatment and 82% with its polyplex.

Discussion: The use of novel polymer Poly[N,N-Dimethylaminoethyl Methacrylate-co-Hydroxyl-Bearing Oligo(Ethylene Glycol) Methacrylate] Arms (P(DMAEMA-co-OEGMA-OH) with star-like structure has been shown as an efficient tool for nucleic acids delivery into cells (Funded by National Science Centre, Contract No. UMO-2020/37/N/NZ2/01125).

Published: June 2023

Polyetheretherketone (PEEK) has been widely used in the medical field as an implant material, especially in bone tissue engineering and orthopedic surgery, in recent years. This material exhibits superior stability at high temperatures and is biosecured without harmful reactions. However, the chemical and biological inertness of PEEK still limits its applications. Recently, many approaches have been applied to improve its performance, including the modulation of physical morphology, chemical composition and antimicrobial agents, which advanced the osteointegration as well as antibacterial properties of PEEK materials. Based on the evolution of PEEK biomedical devices, many studies on the use of PEEK implants in spine surgery, joint surgery and trauma repair have been performed in the past few years, in most of which PEEK implants show better outcomes than traditional metal implants. This paper summarizes recent studies on the modification and application of biomedical PEEK materials, which provides further research directions for PEEK implants.
Engineering the methylotrophic yeast Ogataea polymorpha for lactate production from methanol

Published: June 2023

Introduction: Lactate has gained increasing attention as a platform chemical, particularly for the production of the bioplastic poly-lactic acid (PLA). While current microbial lactate production processes primarily rely on the use of sugars as carbon sources, it is possible to envision a future where lactate can be produced from sustainable, non-food substrates. Methanol could be such a potential substrate, as it can be produced by (electro)chemical hydrogenation from CO2.

Methods: In this study, the use of the methylotrophic yeast Ogataea polymorpha as a host organism for lactate production from methanol was explored. To enable lactate production in Ogataea polymorpha, four different lactate dehydrogenases were expressed under the control of the methanol-inducible MOX promoter. The L-lactate dehydrogenase of Lactobacillus helveticus performed well in the yeast, and the lactate production of this engineered strain could additionally be improved by conducting methanol fed-batch experiments in shake flasks. Further, the impact of different nitrogen sources and the resulting pH levels on production was examined more closely. In order to increase methanol assimilation of the lactate-producing strain, an adaptive laboratory evolution experiment was performed.

Results and Discussion: The growth rate of the lactate-producing strain on methanol was increased by 55%, while at the same time lactate production was preserved. The highest lactate titer of 3.8 g/L in this study was obtained by cultivating this evolved strain in a methanol fed-batch experiment in shake flasks with urea as nitrogen source. This study provides a proof of principle that Ogataea polymorpha is a suitable host organism for the production of lactate using methanol as carbon source. In addition, it offers guidance for the engineering of methylotrophic organisms that produce platform chemicals from CO2-derived substrates. With reduced land use, this technology will promote the development of a sustainable industrial biotechnology in the future.

Novel minimally invasive strategies are needed to obtain robust bone healing in complex fractures and bone defects in the elderly population. Local cell therapy is one potential option for future treatment. Mesenchymal stromal cells (MSCs) are not only involved in osteogenesis but also help direct the recruitment of macrophages during bone regeneration via MSC-macrophage crosstalk. The C-C motif chemokine ligand 2 (CCL2) is an inflammatory chemokine that is associated with the migration of macrophages and MSCs during inflammation. This study investigated the use of CCL2 as a therapeutic target for local cell therapy. MSCs and macrophages were isolated from 10 to 12 week-old BALB/c male mice. Genetically modified CCL2 over-expressing MSCs were produced using murine CCL2-secreting pCDH-CMV-mCCL2-copGFP expressing lentivirus vector. Osteogenic differentiation assays were performed using MSCs with or without macrophages in co-culture. Cell migration assays were also performed. MSCs transfected with murine CCL2-secreting pCDH-CMV-mCCL2-copGFP expressing lentivirus vector showed higher levels of CCL2 secretion compared to unaltered MSCs (p < 0.05). Genetic manipulation did not affect cell proliferation. CCL2 did not affect the osteogenic ability of MSCs alone. However, acute (1 day) but not sustained (7 days) stimulation with CCL2 increased the alizarin red-positive area when MSCs were co-cultured with macrophages (p < 0.001). Both recombinant CCL2 (p < 0.05) and CCL2 released from MSCs (p < 0.05) facilitated macrophage migration. We demonstrated that acute CCL2 stimulation promoted subsequent osteogenesis in co-culture of MSCs and macrophages. Acute CCL2 stimulation potentially facilitates osteogenesis during the acute inflammatory phase of bone healing by directing local macrophage migration, fostering macrophage-MSC crosstalk, and subsequently, by activating or licensing of MSCs by macrophage pro-inflammatory cytokines. The combination of CCL2, MSCs, and macrophages could be a potential strategy for local cell therapy in compromised bone healing.
