Authors:   Department of Building Economics, University of Moratuwa, Sri Lanka, Koonkaduwa JR , Sandanayake YG
Published: December 2022

Apartment market can be recognized as one of the marketplaces severely affected due to the unprecedented global pandemic of COVID-19, which is currently driving towards a disequilibrium state. Hence, this paper aimed to investigate the impact of COVID-19 pandemic on the demand and supply of apartment projects in Sri Lanka. The qualitative research approach was followed in order to accomplish the research aim. A comprehensive literature review followed by fifteen semi-structured interviews were conducted with apartment industry experts during the empirical investigation. Collected data was analyzed using manual content analysis. The findings revealed, how each market determinant affected the demand and supply of apartments respectively during the COVID-19 pandemic resulting numerous challenges on the market participants, directing the apartment market towards a disequilibrium state. Urban living fears, demographic shifts, unemployment shocks, consumers’ financial concerns, tourism crisis along with several other factors caused demand to be dropped while approval delays, lesser investments, lack of funding, developers’ failures, market imperfection and construction delays majorly affect the supply of apartments. Although demand for apartments in some market segments showed recovery with the new normal adaptation followed by several positive market aspects, demand dropped within the rental market and upper tier remains constantly. However, supply side is worsening overtime since financial losses are lessening developers’ supplying capabilities, while the crisis within the construction sector getting more affected due to the country’s economic downturn.

Published: December 2022

Selection of the most appropriate procurement method for a proposed project is challenging because there are many factors to be evaluated in deciding. This study focuses on the impact of procurement method on construction time waste, and it was conducted to find how the time wastage varies according to the selected procurement route. Such knowledge is important in making better decisions when selecting a procurement method. Accordingly, the research aim was set to find the significant differences of time waste between traditional and design and build procurement methods. this research was conducted from a quantitative approach, deductive theory data collected through an online survey, and for data analysis using descriptive statistics. Twenty-two (22) number of time waste factors were identified through literature review. survey respondents weighted the significance of each factor between traditional and design and build procurement methods. Ten (10) factors caused significantly higher time waste in traditional method and none of the factors caused higher time waste in design and build method. Accordingly, the study concludes that time waste in traditional procurement is generally higher in traditional procurement method compared to design and build procurement method.
Le monde comme vestige chez Barbey d’Aurevilly
Authors: Knee Philip
Published: December 2022

Métamorphosant le réel en un ensemble de traces, Barbey d’Aurevilly opère dans ses romans un devenir-vestige du monde, qui suscite dans l’imagination de son lecteur une quête de ce qui toujours se dérobe à lui. On distinguera, parmi ces vestiges, ceux du sentiment perdu sur le plan individuel, ceux de la tradition perdue sur le plan de l’histoire, et ceux de la faute sur le plan du récit chrétien. On  s’efforcera surtout de montrer que ces représentations du révolu, tour à tour psychologique, politique et métaphysique, sont sous-tendues par un univers sensible qui se manifeste par un feuilletage de vestiges. Corporels, par la ruine physique des personnages, ils sont aussi paysagers, en inscrivant la perte dans les territoires où ces personnages se meuvent, et ils appellent enfin des paroles médiatrices de la part de gardiens de la mémoire qui en suggèrent une interprétation voilée ou en font deviner le sens.
En quête des mystères de la mémoire sensorielle : manipuler la mémoire affective. Le cas de « Sauvée » de Guy de Maupassant
Authors: Sloutsky Larissa
Published: December 2022

Connaisseur de la psychologie humaine, Maupassant va plus loin encore : il se lance dans l’exploration de l’inconscient en s’interrogeant sur des zones obscures du psychisme. Le conte « Sauvée » inscrit ce questionnement au cœur de la représentation de la mémoire sensorielle involontaire. Le récit mettant en intrigue le ressouvenir sensuel, sollicité à des fins de séduction manipulatrice, l’effet anecdotique de l’aventure rocambolesque masque des niveaux de complexité du sens dépassant la légèreté de l’anecdote. Cet article examine la façon dont le texte travaille les scènes de ressouvenir qui s’articulent en interrelation entre la sphère des sens, le sensoriel et le sensuel, le comportement impulsif, les facteurs socioculturels et l’actualité scientifique, formant un réseau complexe dont les modalités de l’écriture maupassantienne approfondissent le sens.
Remontée ou héritage ? Mémoire(s) de soi chez Yves Bonnefoy poète et traducteur
Authors: Bonanni Sara , Pollicino Simona
Published: December 2022

Compte tenu de l’acception polysémique du mot, cette étude explore les différentes déclinaisons de la « mémoire » dans la pratique de la poésie et de la traduction d’Yves Bonnefoy. Avec ses dernières œuvres, le poète lègue à son lecteur ses « mémoires » d’enfance, en lui confiant la mission dont il investit la poésie : célébrer, contre l’oubli, la « mémoire » de l’expérience partagée avec autrui. En outre, la mémoire constitue en même temps la source et le processus de la création poétique, comme le démontre aussi sa pratique de la traduction. Si la « tâche » du traducteur selon Bonnefoy coïncide avec une recherche, l’exploration des profondeurs de la mer qu’est chaque langue dans le but de faire resurgir de l’étendue sombre et silencieuse de la nuit la lumière d’une parole réparatrice, en traduisant les vers d’autres poètes, Bonnefoy revit l’expérience de la poésie à travers un nouvel acte poïétique, en remémorant chaque fois l’intuition et l’émotion.
Que la mémoire parle ! La rupture du pacte de silence grâce au français dans Manèges de Laura Alcoba
Authors: Guillard Amandine
Published: December 2022

Dans cet article, nous proposons une analyse du roman Manèges de l’autrice franco-argentine Laura Alcoba. Plus précisément, c’est le rapport à la langue française en tant qu’évocatrice de la mémoire argentine qui nous intéresse. Réduite au silence durant son enfance clandestine à Buenos Aires, Laura Alcoba trouve dans cette langue de l’exil une liberté inespérée afin de mettre des mots sur une expérience jusqu’à présent tue et innommée. En tant que médiatrice de la mémoire, la langue française semble l’unique solution pour renouer avec un passé dont l’expression en version originale serait probablement insurmontable pour l’autrice. La distance créée par le français − synonyme de liberté et renaissance − vis à vis de l’espagnol – synonyme de répression et silence − est la condition sine qua non pour que la mémoire, enfin, parle.
NEW FINDINGS FROM PREHISTORIC PERIOD IN WESTERN BLACK SEA REGION: HADRIANOPOLIS (KARABÜK-ESKİPAZAR) PREHISTORIC POTTERY
Authors: KALKAN Emrullah , ÇELİKBAŞ Ersin
Published: December 2022

Hadrianopolis was first settled during the Roman period. Many know it as an archaeological treasure trove, both for late antiquity and–more recently–pre-history. For the latter, a series of handmade red clay pots found in a pit at its necropolis proves this. Moreover, archaeologists have also uncovered walls bearing prehistoric, mortar-free stone masonry techniques that pre-date Hadrianopolis itself. Both findings hints at the existence of prior settlement, albeit brief. Hadrianopolis’s settlers most likely destroyed much of what remained upon digging up the bedrock to build necropolis’s burial pit. Nevertheless, what has survived into the present day–whilst rare-dates back at least five thousand years. Despite limited evidence, research is still on-going–meaning that we have much more to learn.

Nghiên cứu sử dụng nền cát - cao su phế thải để giảm chấn động cho công trình khi có động đất
Authors: Tuấn Vũ Văn , Nguyên Hồ Đình
Published: December 2022

Trong những năm trở lại đây việc nghiên cứu tái sử dụng phế thải để làm vật liệu xây dựng đang ngày càng phổ biến vì tính kinh tế và khả năng giảm ô nhiễm môi trường. Cao su với khả năng giảm chấn động nên khi kết hợp với vật liệu đắp thông thường sẽ tạo thành hỗn hợp lý tưởng để làm nền giảm chấn động cho công trình khi có động đất. Bài báo này sẽ xây dựng mô hình số phần tử hữu hạn (PTHH) để khảo sát cho công trình nhà BTCT 4 tầng (cao 12m) và 1 tầng hầm sâu 2m với bốn trường hợp: nền cát thông thường và nền cát có 25%, 50%, 75% thể tích là cao su. Khả năng giảm chấn động cho công trình khi có động đất sẽ được đưa ra sau khi so sánh nội lực, chuyển vị, gia tốc của một số điểm trên kết cấu và trong nền của mô hình khảo sát. Kết quả cho thấy hàm lượng cao su trong nền càng cao thì khả năng giảm chấn càng lớn. Sự suy giảm về vận tốc, gia tốc trên kết cấu là rõ rệt; còn sự suy giảm về vận tốc, gia tốc tại nền đất thì chưa thực sự rõ ràng. Đối với nội lực của cấu kiện thì suy giảm của lực cắt sẽ lớn hơn suy giảm của mô men.

Authors: Sarbidi Sarbidi
Published: December 2022

Sampai saat ini, pelayanan air minum  di Indonesia baru tercapai sekitar 70%. Perlu tambahan 30% untuk mencapai target layanan 100% pada akhir tahun 2019. Salah satu solusi  percepatan layanan air minum  adalah mengembangkan dan menerapkan  teknologi uprating instalasi pengolahan air (IPA), karena dapat dihasilkan debit produksi (2-3) kali lipat dari debit  semula,  air olahan memenuhi kualitas air minum dan dapat dikerjakan dengan biaya (4-5) kali  lebih murah dibanding membangun instalasi yang baru. Untuk itu diperlukan adanya kebijakan baru, berupa  penerapan uprating dengan ketentuan: (1) Uprating adalah bagian dari tanggung jawab pemerintah pusat, pemerintah daerah dan Perusahaan Daerah Air Minum (PDAM). (2) Uprating adalah sebahagian dari pekerjaan rehabilitasi Sistem Penyediaan Air Minum (SPAM). (3) Uprating didukung dengan kebijakan, program khusus dan skema pembiayaan dari pemerintah pusat dan daerah serta PDAM. (4) menerapkan teknologi hasil inovasi yang handal dan (5) menjadikan air tak berekening (nonrevenue water, NRW) hingga batas yang ditoleransi secara nasional.
Persepsi Masyarakat Terhadap Nilai-Nilai Signifikan Demi Keberlanjutan Pusaka Perkotaan
Authors: Meutia Zya Dyena , Akbar Roos , Zulkaidi Denny
Published: December 2022

Penelitian ini bertujuan untuk memberi kontribusi pemahaman mengenai nilai-nilai signifikan yang membentuk pusaka dan merumuskannya dari pemahaman persepsi masyarakat. Dalam literatur, pusaka adalah proses budaya dan sosial yang berhubungan dengan kegiatan mengingat dan membentuk identitas. Tentunya pemahaman ini berbeda dari gagasan bahwa pusaka hanya berupa objek material yang memiliki nilai sejarah dan estetika saja. Penelitian ini menggunakan metode kualitatif eksploratif dengan pengumpulan data menggunakan survei online dalam bentuk kuesioner dan mengambil kasus di kawasan yang terkena dampak bencana tsunami 2004 di Banda Aceh yaitu kawasan kapal PLTD Apung, Masjid Uleu Lheu dan sekitarnya yang terdapat pemakaman massal, hutan bakau dan tempat-tempat lain yang muncul pascabencana. Hasil analisis dan data survey menunjukkan bahwa teori yang didominasi oleh pemahaman barat berfokus pada nilai-nilai material, usia, autentisitas dan integritas kurang berlaku dalam kasus pascabencana dimana yang lebih signifikan adalah nilai-nilai intangible seperti nilai memori, spiritual, konsensus, pengetahuan lokal dan nilai-nilai lainnya yang perlu dipikirkan kembali sebagai dasar dalam menetapkan sebuah kawasan pusaka demi keberlanjutan pusaka perkotaaan.

Authors: Indrayani Indrayani , Asfiati Sri
Published: December 2022

Kegiatan manusia secara langsung atau tidak langsung maupun akibat proses alam menyebabkan kualitas udara turun sampai ke tingkat tertentu sehingga menyebabkan lingkungan menjadi kurang atau tidak dapat berfungsi lagi sesuai peruntukannya. Semakin meningkatnya pertumbuhan suatu kota beriringan dengan meningkatnya kegiatan manusia dan bertambahnya jumlah kendaraan di perkotaan  maka mengakibatkan komposisi udara ambien mengalami perubahan kualitas. Terjadinya penurunan kualitas udara diakibatkan kendaraan bermotor di jalan yang padat. Akibat penurunan kualitas tersebut dapat mengganggu dan membahayakan lingkungan sekitar terutama manusia, hewan serta tumbuhan. Penelitian ini dilakukan di tiga lokasi di Kota Medan dengan tingkat kepadatan lalu lintas yang cukup tinggi, yaitu Jalan Gatot Subroto, Jalan Gagak Hitam, Jalan Sisingamangaraja. Dari hasil analisis menggunakan Statistical Package for the Social Sciences (SPSS) diketahui bahwa volume lalu lintas berpengaruh signifikan terhadap kualitas udara ambien. Umumnya pengaruh tersebut didominasi oleh angkutan barang sedangkan angkutan penumpang hanya memberikan pengaruh yang kecil, namun pengaruh tersebut dapat bertambah besar apabila volume lalu lintas padat di suatu jalan. Untuk besaran pengaruh kinerja lalu lintas terhadap kualitas udara ambien sebesar 28,07% dan sisanya di pengaruhi faktor lain. Hasil tersebut cukup besar untuk satu parameter pencemar udara di perkotaan.

YEMEN’DE OSMANLI-İNGİLİZ SINIR GÖRÜŞMELERİ GÖLGESİNDE YAPILAN ANTLAŞMA: DEAN(YEMEN) İ’TİLAFNAMESİ VE OSMANLI MATBUATI
Authors: SARI Ali
Published: December 2022

19. yüzyıldan itibaren artık çöküş evresine giren Osmanlı Devleti bir takım yerel isyanlarla mücadele etmek zorunda kalımıştır. Devleti; askeri, siyasi ve ekonomik olarak güç durumda bırakan isyanlardan biri de Yemen’de bulunan İmam Yahya isyanıdır. İlk olarak 1904-1905 yıllarında isyan eden İmam Yahya, başarılı olamamış ancak tamamen de bertaraf edilememiştir. 1905’ten sonra isyan için uygun zamanı bekleyen İmam, Meşrutiyetin yeniden ilan edilerek II. Abdülhamid’in hal edildiği siyasi buhran döneminde ikinci kez isyana kalkışmıştır. İttihat Terakki yönetimi isyanı bastırmakta başarısız olunca 1911 yılında İmam Yahya ile bazı maddeleri gizli olan bir İtilafname imzalamıştır. Resmi evrakta Yemen İtilafnamesi olarak geçen bu anlaşma Yemen’de bir takım idari ve siyasi değişiklikleri de beraberinde getirmiştir.

II. Meşrutiyet döneminde sansürün kaldırılması ile birlikte ülkede birçok yeni gazete yayın hayatına başlamıştır. Bu gazeteler arasında İttihat Terakki’ye yakın olanların yanında ona muhalefet edenler de mevcuttu. Bu gazetelerin hemen hepsi değişik siyasi fikirleri savunuyordu. Bu nedenle aynı konu gazete sütunlarında farklı şekillerde tartışılıyordu. Yemen itilafnamesi de imza edildikten sonra gazetelerde belirli süre de olsa tartışılan konulardan biri olmuştu. Gazetelerin farklı siyasi fikirlere sahip olması anlaşmayı farklı şekilde yorumlamalarını da beraberinde getirmiştir. Bunun yanında anlaşma maddelerinin bir kısmının gizli olması gazetelerin de meseleyi tam kavrayamamasına neden olmuştur. Tanin, Alemdar, Basiret, Sabah gibi önde gelen gazetelerdeki haberlerle Osmanlı arşivindeki anlaşma metni karşılaştırdığımızda bunu rahatlıkla görebiliyoruz. Bu makalede o dönemde yayın yapan gazetelerin konuyu ele alış biçimleri ve o dönemki matbuatın konudan ne kadar haberdar oldukları anlaşılmaya çalışılacaktır.

Evolucijski gledano, znanstveni dokazi upućuju da je život nastao u pretečama vodenih ekosustava kao nakupinama toplog blata bogatog hranjivim tvarima i mineralima. Ove vrste blata, također zvane peloidi, nastaju nakupljanjem organskih tvari i njihovim miješanjem sa anorganskim tvarima iz gline. Miješanje pospješuju slatka i morska voda bogate mineralima. Nalazišta peloida su često plitke i zatvorene lagune, stalno izložene visokom UV zračenju, koncentraciji soli i temperaturi, zapravo ekstremna okruženja za život brojnih mikroorganizama. Mikroorganizmi koriste minerale iz okoliša, razlažu organske tvari, dakle ostatke biljaka i drugih makro i mikroorganizama i prilikom prilagodbe na okolišne uvjete sintetiziraju široku paletu primarnih i sekundarnih metabolita s ciljem obrane i prilagodbe na ekstremne uvjete okoliša. Na ovaj način sintetizirani metaboliti imaju brojno i raznoliko djelovanje, a svoju potencijalnu primjenu pronalaze u biotehnološkoj, kozmetičkoj i farmaceutskoj industriji. Unatoč dva tisućljeća stare i dokazane uporabe u ljekovite i medicinske svrhe, ali i jake turističke i medijske promocije, u modernom je razdoblju mali broj znanstvenika svoje znanje i sposobnost okušao u istraživanju ljekovitosti i dokazivanja dobrobiti ili pak štetnosti uporabe i terapije ninskim peloidom na ljudsko tijelo. Studija temeljena na znanstvenom istraživanju, zajedno sa sastavljanjem racionalnog i održivog plana uporabe ninskog peloida kao prirodnog resursa, bila bi temelj potencijalne komercijalizacije nalazišta i njegove primjene u medicinskoj, farmaceutskoj i biotehnološkoj industriji.

Published: December 2022

Fresh-cut apples provide consumers convenient, fresh, ready-to-eat product. However such products are susceptible to browning and microbiological spoilage which occurs very quickly after processing. Due to their antimicrobial properties, essential oils have a potential stabilizing effect on fresh-cut products, but could have undesirable effects on their color or taste. The aim of this study was to investigate the effect of laurel essential oil (LEO) treatment at different concentrations (25, 75, 125 and 175 mg L-1) on the shelf-life (aerobic mesophilic bacteria count) and physical (soluble dry metter, pH, color, texture) and sensory characteristics of fresh-cut apples during 10 days of storage at 8 °C. Number of aerobic mesophilic bacteria decreased with the increase of LEO concentration and it slightly increased with the increase of storage time. In general, samples treated with 75 mg L-1 LEO had the lowest and samples treated with 175 mg L-1 LEO the highest soluble dry matter, while pH trend was vice versa. Soluble dry matter, pH, and firmness increased during storage. Apples treated with 75 mg L-1 LEO after 10 days of storage showed the least color change. This study showed that LEO can be used to preserve and enrich sensory characteristics of fresh-cut apples, especially at a concentration of 75 mg L-1. Generally, this LEO concentration can be recommended regarding the results of microbiological and sensory analysis as well as results of soluble dry matter, pH, color parameters and firmness.
János Bolyai's Angle Trisection Revisited

Published: December 2022

J. Bolyai je predložio elegantnu metodu za trisekciju kuta određivanjem sjecišta lukova jedinične kružnice s lukovima jednakostranične hiperbole c. Vrijedno je istražiti geometrijsku pozadinu ovog postupka te ga koristiti kao temeljnu ideju za pronalaženje n-tog dijela zadanog kuta. U ovom radu primijenit ćemo navedenu ideju u trivijalnom slučaju n = 4, te za n = 5. Slijedeći Bolyaija, u slučaju n= 5 jediničnu kružnicu treba presjeći kubnom krivuljom c. U tom slučaju, kao i u slučajevima n \geq 5, nalazimo samo numerička rješenja, što pokazuje ograničenost Bolyaijeve metode. Stoga predlažemo i drugu konstrukciju, ovaj put utemeljenu na epicikloidi upisanoj jediničnoj kružnici. Ovom metodom moguće je čak konstruirati n/m-ti dio zadanog kuta.

Determination of suitable distance between methane drainage stations in Tabas mechanized coal mine (Iran) based on theoretical calculations and field investigation
Authors: Hosseini Ali , Najafi Mehdi , Morshedy Amin
Published: December 2022

A large amount of gas is emitted during underground mining processes, so mining productivity decreases and safety risks increase. Efficient methane drainage from the coal seam and surrounding rocks in underground mines not only improves safety but also leads to higher productivity. Methane drainage must be performed when the ventilation air cannot dilute the methane emissions in the mine to a level below the allowed limits. The cross-measure borehole method is one of the methane drainage methods that involves drilling boreholes from the tailgate roadway to an un-stressed zone in the roof or floor stratum of a mined seam. This is the main method used in Tabas coal mine N 1. One of the effective parameters in this method is the distance between methane drainage stations, which has a direct effect on the length of boreholes required for drainage. This study was based on the measurement of ventilation air methane by methane sensors and anemometers placed at the longwall panel as well as measuring the amount of methane drainage. Moreover, in this study, the obtained and analyzed data were used to determine the suitable distance between methane drainage stations based on the cross-measure borehole method. In a field test, three borehole arrangements with different station distances in Panel E4 of Tabas coal mine N 1 were investigated. Then, the amounts of gas drained from these arrangements were compared with each other. The highest methane drainage efficiency was achieved for distances in the range of 9-12 m between methane drainage stations.
Drilling of deep and ultra-deep wells for prospecting and exploration of new raw mineral fields
Authors: Dvoynikov Mikhail , Sidorkin Dmitrii , Yurtaev Sergei , Grokhotov Evgenii , Ulyanov Dmitrii
Published: December 2022

Scientific and technological progress over the last century has led to an enormous increase in the consumption of minerals, including energy resources. Most of the exploited oil and gas fields are already considerably depleted, so it is necessary to search for new hydrocarbon resources, particularly at great depths. Deep drilling plays a special role in solving this problem. The article considers the world and Russian experience of ultra-deep wells drilling. The me-thods and technologies used in the construction of wells, as well as complications and accidents occurring during their drilling were analyzed. The analysis revealed that the existing limitations for drilling parameters of deep and ultra-deep wells are caused by the technical characteristics of surface and bottomhole drilling equipment, which do not meet the extreme drilling conditions. The directions for development of deep and ultra-deep well drilling machinery and technologies are suggested. The notion of extreme rock and geological drilling conditions is introduced, which describes drilling in conditions of hydrostatic pressure of flushing fluid column and high bottomhole temperature both at stable and unstable wellbore conditions, coming close to the upper limit of operating technical characteristics of bottomhole assembly, the drill string and flushing fluid.
Predicting the permeability of the near-bottomhole zone during wave impact

Published: December 2022

The research reveals that during selection of a method to increase oil recovery it is necessary to take into account rheological features of fluid movement through the formation, effect of capillary forces and heterogeneity of reservoir properties of the productive formation in thickness and along the bedding. Low-frequency wave impact, which is used to increase production in oil fields, is considered. At low-frequency impact new fractures appear and existing fractures in rocks increase in size. The greatest increase in porosity and permeability of rocks occurs at an impact frequency up to 10 Hz. Dynamics of oscillation amplitude during wave's movement in saturated porous medium is studied in the paper: essential attenuation of amplitude occurs at distance up to 1 m from borehole axis. With increase of frequency from 1 to 10 Hz the intensity of amplitude's attenuation decreases. The technology was tested on a well in Perm region (Russia). The actual permeability value was 50 % higher than the predicted value. According to the results of hydrodynamic investigations processing, it was noted that the greatest increase of permeability took place near the wellbore, while away from the wellbore axis permeability remained almost unchanged. In order to refine the mathematical model for prediction of wave impact on rock permeability it is necessary to take into account interconnection of pore space structure, change of adhesion layer, as well as to study transfer of particles during vibration.

The problem of selecting a method for ensuring the reliability of the unprepared fluid transport facilities of an unprepared fluid in the presence of carbon dioxide is considered. Carbon dioxide corrosion is one of the dangerous types of damage to field and main pipelines. It has been shown that dynamic autoclave tests should be carried out during staged laboratory tests in order to determine the intensity of carbon dioxide corrosion and to select the optimal method of protection. A hypothesis about the imperfection of the existing generally accepted approaches to dynamic corrosion testing has been put forward and confirmed. A test procedure based on the use of an autoclave with an overhead stirrer, developed using elements of mathematical modeling, is proposed. The flows created in the autoclave provide corrosive wear of the sample surface similar to the internal surfaces elements wear of the pipelines piping of gas condensate wells. The autoclave makes it possible to simulate the effect of the organic phase on the flow rate and the nature of corrosion damage to the metal surface, as well as the effect of the stirrer rotation speed and, accordingly, the shear stress of the cross section on the corrosion rate in the presence/absence of a corrosion inhibitor. The given results of staged tests make it possible to judge the high efficiency of the developed test procedure.

Published: December 2022

When the shuffled frog leaping algorithm (SFLA) is used to solve the robot path planning problem in obstacle environment, the quality of the initial solution is not high, and the algorithm is easy to fall into local optimization. Herein, an improved SFLA named ISFLA combined with genetic algorithm is proposed. By introducing selection, crossover and mutation operators in genetic algorithm, the ISFLA not only improves the solution quality of the SFLA, but also accelerates its convergence speed. Moreover, the ISFLA also proposes a location update strategy based on the central frog, which makes full use of the global information to avoid the algorithm falling into local optimization. By comparing ISFLA with other algorithms including SFLA in the map environment of different obstacles, it is confirmed that ISFLA can effectively improve the minimum path optimization and robustness in the simulation experiments of mobile robots.

Published: December 2022

Background:

The motor impairment in Parkinson’s disease (PD) can be managed but effective treatments for stopping or slowing the disease process are lacking. The advent of transcriptomics studies in PD shed light on the development of promising measures to predict disease progression and discover novel therapeutic strategies.

Objective:

To reveal the potential role of transcripts in the motor impairment progression of patients with PD via transcriptome analysis.

Methods:

We separately analyzed the differentially expressed genes (DEGs) between PD cases and healthy controls in two cohorts using whole blood bulk transcriptome data. Based on the intersection of DEGs, we established a prognostic signature by regularized regression and Cox proportional hazards analysis. We further performed immune cell analysis and single-cell RNA sequencing analysis to study the biological features of this signature.

Results:

We identified a two-gene-based prognostic signature that links to PD motor progression and the two-gene signature-derived risk score was associated with several types of immune cells in blood. Notably, the fraction of neutrophils increased 5% and CD4+ T cells decreased 7% in patients with high-risk scores compared to that in patients with low-risk scores, suggesting these two types of immune cells might play key roles in the prognosis of PD. We also observed the downregulated genes in PD patients with high-risk scores that enriched in PD-associated pathways from iPSC-derived dopaminergic neurons single-cell RNA sequencing analysis.

Conclusion:

We identified a two-gene signature linked to the motor progression in PD, which provides new insights into the motor prognosis of PD.

Published: December 2022

The standard of care for localized renal cell carcinoma (RCC) is radical or partial nephrectomy. Despite complete resection, a subset of patients will develop locoregional recurrence or metastatic disease. Adjuvant immunotherapy has been studied since the 1980 s as the primary method to mitigate tumor recurrence after definitive surgery. We herein discuss published and ongoing clinical trials investigating adjuvant therapy in localized or locoregional RCC.

Published: December 2022

BACKGROUND: Complex behaviors, such as physical activity (PA), may be related to different levels of influence. OBJECTIVE: To analyze the role of social support, mood and alcohol consumption as psychosocial predictors on the engagement in PA among Brazilian workers. METHODS: This is a quantitative, cross-sectional analytical study. A sample of 395 participants answered a sociodemographic questionnaire, the Alcohol Use Disorder Identification Test (AUDIT), the Baecke Habitual Physical Activity Questionnaire, the Social Support Scale for Physical Activities (SSSPA) and the Brunel Mood Scale (BRUMS). RESULTS: Analysis via Pearson’s Correlation Test indicated a negative correlation between PA and depression and fatigue, and a positive correlation between PA and alcohol consumption, vigor and the four variables of social support (support of family members for walking; support of friends for walking; support of family members for moderate and vigorous physical activity; support of friends for moderate and vigorous physical activity). A positive relationship between PA and low-risk alcohol consumption was also identified. A hierarchical multiple regression analysis showed that family support for walking, friends support for moderate and vigorous physical activity, vigor and alcohol consumption are predictors of PA. Hayes’ moderation analysis indicated that social support has a moderating effect on the relationship between alcohol use and PA. CONCLUSION: Different factors may be involved in engaging in PA. A broader approach that addresses the singularities of individuals, especially in actions for different patterns of alcohol consumption, is recommended.

Published: December 2022

BACKGROUND: Studies found that women with breast cancer struggle with significant physical and mental challenges that affect their participation in daily living, social and work activities. Although women express their need for rehabilitation, in Israel there has been scant research on the nature of these needs. OBJECTIVE: To examine the implications of breast cancer for Israeli women in terms of their quality of life, body function, activities and participation in all facets of life, including work. METHODS: The sample was composed of women diagnosed with breast cancer. The data were collected through: (a) an online electronic survey assessing cancer-related quality of life (QoL), function and disability, fatigue and sensory-motor functions, (n = 120) followed by (b) face-to-face interviews and assessments (n = 20), and a healthy control group (n = 61). RESULTS: Women with breast cancer reported significantly lower QoL compared to the healthy control group. They reported higher levels of disability in areas such as, cognition, mobility, upper extremity, as well as overall difficulties in self-care, doing routine household activities and return to work. Roughly one-third of the women did not return to work. Interestingly, our sample did not perceive a decline in terms of their social support or networks, the women stated that family and social support were major enabling factors. CONCLUSION: The results show that breast cancer has short and long-term functional effects on most facets of these women’s life. The women’s social support system served as an enabling factor. Many women expressed their frustration at the lack of rehabilitation services for their condition and needs in Israel.
Precarious employment, precarious life? A qualitative study exploring the perspective of temporary agency workers and their households
Authors: Bosmans Kim
Published: December 2022

BACKGROUND: Previous research demonstrated the negative consequences of precarious employment for the health and well-being of employees. However, the broader social consequences of precarious employment are under-examined. OBJECTIVE: This study explores the broader impact of precarious employment on the life course, family and social life of households. A multi-actor perspective is adopted, considering the perspectives of different household members. METHODS: For this aim, in-depth (household) interviews among temporary agency workers in Belgium are conducted. RESULTS: The results reveal that precarious employment influences the life course and family and social life in three ways: (1) by hindering or facilitating life course events and transitions of household members, (2) by influencing the daily life and household planning, and (3) by influencing the mood of household members. CONCLUSION: The consequences of precarious employment reach further than the work environment; they impact the life course, and social and family life of workers. Moreover, precarious employment does not only influence the workers themselves, but also their household members, which is often forgotten in studies. Therefore, policy makers should consider the far-reaching consequences of precarious employment when developing (flexible) labour market policies.
