Evaluation of the Effectiveness of Traffic Calming Measures by SPEIR Methodology: Framework and Case Studies
Authors: Distefano Natalia , Leonardi Salvatore
Published: June 2022

The speed value of 30 km/h should not be exceeded in urban areas, both to ensure safety requirements for all categories of users and to improve the overall quality of life in urban areas. Moreover, it is necessary not only to comply with the prescribed maximum speed, but also to ensure a uniform speed by limiting the variations in relation to the average value within an acceptable range of variation. An original analysis methodology is therefore proposed, useful for both technicians and administrators to verify the effectiveness of traffic calming measures, especially in areas where these measures are widely used, such as Zones 30. This methodology, called SPEIR (acronym for Speed Profile, Effectiveness Indicators and Results, which are the keywords of the three steps into which the proposed methodology is divided), is divided into three operational steps necessary to both verify the effectiveness of existing traffic calming measures in a given context and to plan new traffic calming measures to be implemented in specific urban sectors to be requalified and revitalized. Finally, three case studies are presented where the application of the SPEIR methodology is useful not only for understanding the operational steps in the application of the methodology itself, but also for understanding the differences in terms of the safety performance that the various traffic calming measures provide to the users of the urban streets where such measures are present.
Spatial Distribution and Accessibility of High Level Scenic Spots in Inner Mongolia
Authors: Wu Xinyang , Chen Chuying
Published: June 2022

Based on the data of high-level scenic spots in Inner Mongolia, the methods of the nearest neighbor index, kernel density, accessibility, and spatial autocorrelation are used to systematically sort out the spatial distribution pattern, accessibility, and influencing factors of various types of scenic spots. The following conclusions are drawn from the analysis. The spatial distribution of different types of tourist attractions in Inner Mongolia is in a state of “small agglomeration and large dispersion”. The spatial accessibility of different types of tourist attractions in Inner Mongolia is generally poor, and the temporal accessibility presents an inverted U-shaped distribution over time. The county-level accessibility of different types of scenic spots in Inner Mongolia is relatively poor, basically showing an oblique distribution pattern of low in the west and high in the east. The influencing factors of the spatial distribution pattern and accessibility of various scenic spots in Inner Mongolia mainly include the natural environment, transportation network, resource endowment, and economic level. This study proposes an optimal path for accessibility according to the aspects of the design of tourism scenic areas in a circle and the construction of tourist traffic and facilities, as well as the linkage design of tourist routes.

Authors: Sulca Contreras Ronny Daniel
Published: June 2022

El presente artículo estuvo orientado en encontrar las relaciones existentes entre el nivel de empleabilidad definido en no empleo, subempleo y empleo de los egresados universitarios y sus habilidades blandas, tomando como caso de estudios los egresados de la Universidad Nacional Federico Villarreal de Lima-Perú a los cuales se les aplicó un cuestionario virtual donde se obtuvo un total de 877 encuestas. A través del algoritmo Stepwise se realizó la calibración del modelo logístico multinomial entre los niveles de empleo definidos y habilidades blandas, las cuales fueron medidas mediante los test de Grit y Big Five, así como preguntas complementarias de escala Likert. Los resultados muestran que habilidades blandas como la perseverancia aumentan la probabilidad de subempleo, mientras que la ambición aumenta la probabilidad de no estar empleado. Otras habilidades como el liderazgo, solución de problemas y trabajo en equipo, aumentan las probabilidades de subempleo en los egresados.

Les vestiges humains gravettiens de la grotte de Gargas (Aventignan, France) : datations 14C AMS directes et contexte chrono-culturel)
Authors: Foucher Pascal , San Juan-Foucher Cristina , Villotte Sébastien , Bayle Priscilla , Vercoutère Carole , Ferrier Catherine
Published: June 2022

La grotte de Gargas fait l’objet d’un programme de recherche depuis 2004. Cet article précise le cadre chronologique et stratigraphique des vestiges humains trouvés dans la couche d’habitat gravettien de la Galerie inférieure. Ils correspondent à une mandibule d’enfant (entre 1 et 3 ans), une clavicule gauche d’enfant (entre 1 et 7 ans), un fragment de neurocrâne, une dent monoradiculé déciduale, un fragment de clavicule (sujet immature), un fragment de côte, et à une diaphyse de fémur (sujet adulte). Les cinq premiers ont été découverts in situ, le sixième dans les remblais des fouilles anciennes ; le fragment de fémur avait été trouvé lors des fouilles d’É. Cartailhac et d’H. Breuil, en 1911 et 1913. Au moins trois sujets semblent être représentés dans cet assemblage : un jeune enfant (mandibule), un sujet adulte (fémur), et un enfant plus âgé (dent déciduale à la racine résorbée) : seuls les deux premiers pourraient s’intégrer dans un contexte funéraire lato sensu qu’il s’agira de préciser dans les années à venir. La mandibule et le fémur ont fait l’objet d’analyses 14C AMS directes. Les résultats sont respectivement 24 930 ± 220 BP (29500‑28532 cal. BP) et 24 880 ± 140 BP (29 310-28 593 cal. BP). Puis, ces datations sont mises en perspective par rapport à celles obtenues sur les vestiges de faune consommée dans l’habitat. Si l’on considère la distribution et la concentration significative des dates, on peut définir deux séquences principales d’occupation : la première se situe entre 31 500 et 30 000 cal. BP, la seconde entre 29 500 et 28 500 cal. BP. Les dates des restes humains se placent dans la phase finale des occupations de la grotte.
Une sépulture du premier âge du Fer en moyenne vallée du Rhône : Lautagne (Valence, Drôme)
Authors: Dedet Bernard , Buffat Loïc , Kielb-Zaaraoui Magalie
Published: June 2022

La fouille d’un camp romain sur le site de Lautagne à Valence (Drôme) a permis la découverte d’une tombe à incinération du VIIe s. av. J.-C., isolée, hors de tout ensemble funéraire, mais non loin d’un petit habitat à peu près contemporain. Cette tombe permet de mieux appréhender les usages funéraires du début de l’âge du Fer dans la moyenne vallée du Rhône, une région où ceux-ci sont encore peu documentés, ce qui accroît l’intérêt de cette découverte. Si la partie supérieure de la sépulture n’est pas conservée, il subsiste néanmoins la totalité du loculus et de son contenu. Le défunt incinéré, âgé d’environ 18 ans, est probablement une adolescente si l’on en croit la parure qui l’a accompagnée sur le bûcher : une boucle d’oreille, un bracelet et deux anneaux de jambes en bronze et un collier de perles en bronze ou en ambre. Ce matériel a été placé, mêlé aux os, dans une urne-ossuaire fermée par une coupe, toutes deux en céramique non tournée. Le loculus, juste à la dimension de ces derniers, ne contenait aucun autre dépôt. Comparée aux rares découvertes faites aux confins de la Drôme et du Vaucluse et dans le nord du Gard rhodanien, la tombe de Lautagne permet de dégager une certaine originalité des pratiques locales : l’utilisation de vases de morphologie et d’aspect fort semblables, qu’ils servent d’ossuaire ou de contenant de denrées ; la parure des chevilles du mort par des anneaux ou jambelets de forme et décor très proches ; l’assemblage des mêmes types d’objets de parure. Mais au-delà de ce particularisme, cette tombe s’intègre tout à fait dans le contexte du passage de l’inhumation à l’incinération dans cette partie du Sud-Est, au cours du VIIe s. av. J.-C.
Opening up the University for a Multi-directed Lifelong Professional Development
Authors: Mozelius Peter
Published: June 2022

In a time when most countries are facing a rapidly emerging knowledge society, the investment in human resources is essential for companies and organisations. In parallel, technology enhanced learning has enabled more flexible forms of professional development with work-integrated learning, an interesting shift that also challenges the traditional university model. An interesting concept for realising the work-integrated learning principle of solving practical problems in the industry with the use of theory from academia, is to let participants and companies to bring their own data (BYOD). This study was based on the BUFFL project, where BYOD activities have been an essential part of course design and learning activities for bank and insurance company staff.  A project that is a cross-disciplinary collaboration between six companies, three universities, and researchers from different university departments. The aim of this study is to present, analyse and discuss the design and implementation of a pilot project for a technology enhanced and multi-directed lifelong professional development. The main research question to answer was: "What are the bank and insurance company staff perceptions of the BUFFL project design of technology enhanced professional development, and the idea of bringing their own data to course activities?"  

Data for a preliminary project evaluation has been gathered by course evaluation questionnaires from 14 instances of 9 course modules. Questionnaires comprised 30 questions with a mix of Likert-scale questions and questions with open-ended free-text answers. In a strive to find the data that have a potential to answer the research question 10 Likert-scale questions and 4 free-text questions were selected. Results from the Likert-scale questions were presented as a descriptive statistical analysis that discusses frequency, central tendency and variation. Open-ended free-text answers have been categorised in an deductive thematic analysis and compared to the results from the Likert-scale questions. Findings indicate that a technology enhanced and workplace integrated course design is appreciated, when information and communication technologies work. On the other hand, technology incidents have caused irritation and the provisional support model needs a further development that also could survive the project span. The earlier complaints on too theoretical course literature, and that course design lacks adaption to the participants actual workplace situations are contradicted by the result of the quantitative analysis. However, there are also indications that universities have to open up further, in a shift to a more multi-directed communication and knowledge sharing between academia, industry and society. Finally, even if course modules are given on a 25% pace, the current workload can be demanding for full-time working participants.
Strength of the word of the qualification that does not feature in Silambu
Authors: P Sivasankari
Published: June 2022

We still read poets who greeted kings during the Sangam period. In this way, we learn that the single word "live" is an everlasting hope in our lives. In the same way, even today, during the wedding ceremony, the faint sound is played during the wedding ceremony so that the words do not join the bride and groom. It is possible to see the use of words without the knowledge of many of the words that create such an effect today. Scholars say that if the mind is high, it will be high in language. We would have heard our ancestors say, Karunaku, do not open your mouth. It is an undeniable fact that all this is not just an empty belief but a statement of the strength of the words. However, this article has been written with the intention of exploring how the word is enduring in the idiom of the first Tamil epic, citizens' epic and feminist epic.
Tolkappiyam and levels of Chastity in Akananuru
Authors: N Malathi
Published: June 2022

Chastity is the state in which the love life of Tamils is centred and manifested.  Chastity is to fully attain the state of mind of genuine love (Kalaviyal).  Chastity is conducting the wedding ceremony (Karanam) with the knowledge of the whole world. Marriages are completed by tying the Mangal Sutra. Even after the lover's misconduct, in the state of women being still considered unworthy, a procedure called ‘Karanam’ is conducted publicly. Chastity sets in to illustrate the way the Man and Women conduct their lives and morality that is well established. Tolkappiyam completely embodies the lifestyles of the people and the personal ideas expressed in the Sangam literature in alliance with the cultural traditions of the people. Tolkaapiyar describes chastity in the form of the ritual itself. It is also called chastity when the parents give away their daughter to the groom; the parents of the groom receive her by a ritual confirmation ceremony. The woman remaining chaste when the man is away from home is said to be happening in the forest (Mullai Nilam). In the life of a lover, a ritual that is being chaste as ‘One man; one woman and one woman; one man’ and living together after marrying publicly is accepted universally.

Authors: Nguyen Diem Thuy
Published: June 2022

The expansion of reclamation work to the South and agricultural production activities in the Southwest region in general and Can Tho in particular since the 17th century has fundamentally changed the natural landscape  in this land, and also this has had a strong impact on the perception of local people in many ways which are quite clearly shown through the geographical names in Can Tho. The cognitive culture about the natural environment through geographical names in Can Tho City is partly reflected in the geographical names that related to accumulated experiences of local people about the river environment, terrestrial flora and fauna system, and residence selection. Based on the application of the theory of cultural linguistics, the theory of cultural regions, especially the natural characteristics of Can Tho, the article focuses on understanding the manifestations of cognitive cultural elements about the natural environment through geographical names, thereby contributing to affirming the indigenous knowledge of the people of this region.

GENIES IN VIETNAMESE LEGEND FROM THE HISTORICAL-CULTURAL PERSPECTIVE
Authors: Nguyen Duyen Huu Kim
Published: June 2022

The genie characters in Vietnamese legends are a topic that attracts many scientists, especially in studying genie characters from the historical-cultural perspective because Vietnamese folk legends are mostly associated with historical stories and national heroes. Moreover, the study of genie characters in the integration  between the study of legend and history is the source of feelings of honor, praise and nationalpride. From this perspective, it shows that the genie characters are historicized, deified, worshiped, and the legends about genies become documents for national history. Folk festivals have become vivid symbols of genies’s beliefs. This signifies the particularly important position of the genies in the legend as well as in theprocess of national history and also in the minds of Vietnamese people for a long time.

SPATIAL AND TEMPORAL VARIABILITIES OF SURFACE WATER QUALITY IN URBAN AND RESIDENTIAL AREAS IN AN GIANG, VIETNAM
Authors: Nguyen Giao Thanh
Published: June 2022

This study aims to assess the surface water quality in both residential areas and urban areas in An Giang Province from 2011 to 2019. Thirteen locations were selected with eight water quality variables at each location;which were temperature, pH, nitrate (NO3--N), total suspended solids (TSS), biochemical oxygen demand (BOD) and chemical oxygen demand (COD), coliforms, and total oil and grease were collected. Surface water quality data were compared with the Vietnamese standards. Cluster analysis (CA) and principal component analysis(PCA) were applied to determine the sampling locations and water variables affecting water quality in the residential and urban areas. The results showed that the parameters of temperature, pH, and NO3- - N were within the allowable limits - while TSS, BOD, COD, coliforms, and total oil and grease exceeded the permitted limit. The results of CA indicated that 13 sampling points could be reduced to 8, saving nearly 40% of the water quality monitoring costs which could be provided the cost for water treatment of water bodies. PCA revealed that at least three sources of pollution could explain 83.7% of the water quality fluctuations. The main sources that affected surface water quality in residential and urban areas could be wastewater, solid wastes, stormwater runoff, and other hydrological factors. Further studies need to investigate and curb the sources of water pollution. It is urgently required to build a system of waste collection and treatment in this study area and at the same time raise public awareness about environmental protection.

Improvement of communication quality in Laguerre–Gaussian mode multiplexing through atmospheric turbulence propagation for optical wireless communication
Authors: Yada Konami , Ogawa Kayo
Published: June 2022

The recent rapid increase in communication traffic has led to the development of 6G technology, and high-frequency carrier wave bands have been studied toward the implementation of this technology. Ultrahigh-speed and high-capacity communication are also required for backhaul lines. One of the methods to realize the above is orbital angular momentum (OAM) mode multiplexing communication. To this end, a mode multiplexing system that can simultaneously separate multiple modes with a single filter using multiplexed holograms as mode demultiplexing filters has been realized using Laguerre–Gaussian (LG) beams extending the OAM. However, the receiving aperture, LG mode combination guideline to reduce crosstalk, and feasible optical wireless communication have not been investigated. Therefore, in this study, we implemented LG mode multiplexing from the viewpoint of the receiving aperture and mode combination involving long-distance propagation through atmospheric turbulence.

Forecasting or prediction in production activities is an activity that aims to predict everything related to production, supply, demand, and use of technology in an industry. In the end, this prediction is often used by companies and operational management to make plans related to their business activities in certain periods. As a tool for measuring the level of predictions that are close to good accuracy which can be used as a reference for calculating a business process in the future, companies also need an accurate and tested measuring tool based on the type of estimate itself. The NEURAL NETWORK  method with backpropagation calculates a pattern based on the history of several periods that have occurred. This method is often used to obtain prediction accuracy in forecasting activities. Inaccurate packaging stock inventory forecasting to support production needs causes the inventory space to exceed capacity and the production process is disrupted, so the selection of an appropriate forecasting method is needed. The use of the NEURAL NETWORK  method with backpropagation to increase the accuracy of the prediction of the procurement of packaged goods in this study is very suitable. Results of Data Training with input data for begin stock, consumption, incoming, and safety stock and target data is the stock order yields the best MSE value of 0.03603642 on the number of neurons 11 with an epoch value of 1000 and a maximum error limit of 6, so that the test data resulted in the accuracy of the MAPE value of 0.52%.

Dengan semakin meningkatnya aktivitas pekerjaan sumur di lokasi PT. Pertamina Hulu Mahakam wilayah Senipah Channel Kabupaten Kutai Kartanegara, peran dermaga sangat penting sebagai penunjang kegiatan transportasi  laut, sehingga diperlukan pemeliharaan jalur kanal tranportasi yang melewati keluar masuknya ke dermaga agar kapal tidak kandas. Untuk melakukan hal tersebut diperlukan adanya analisis perhitungan muatan hasil sedimentasi (pendangkalan)  terhadap  Kedalaman air (Chart Datum) dan  pasang surut (Tide Table). Hasil dari pasang surut terhadap muatan sedimentasi yang terbentuk dapat disimpulkan ketika bilangan formzahl lebih besar dari tahun sebelumnya, maka volume sedimentasi juga akan bertambah. Volume sedimentasi tahun 2017 sebesar 78.300 m3 bilangan formzahl 0,506 dan 2018 sebesar 118.680 m3 bilangan formzahl 0,554. Selisih volume sedimentasi  tahun 2018 dan tahun 2017 sebesar 40.380 m3. Volume sedimentasi tahun 2019 sebesar 82,710 m3 bilangan formzahl 0,518 dan  tahun 2020 sebesar 104.445 m3 bilangan formzahl 0,542, selisih volume sedimentasi tahun 2020 dan tahun 2019 sebesar 21.735 m3, menunjukkan  bahwa volume sedimentasi sebelum dilakukan pengerukan selalu mengalami pertambahan volume yang dapat dilihat dari hasil pengurangan volume sedimentasi sebelum pengerukan. Dalam penelitian ini, dilakukan pengujian melalui https://gtmetrix.com/ dengan memasukkan link alamat dan hasilnya GTmetrix bernilai B dan performance 81% serta structure 86%  artinya kecepatan akses web dapat bekerja dengan baik.

Published: June 2022

Soil communities, the microorganisms, are the initial and primary recipients of hydrocarbons or any xenobiotics incidented on the soil. This study evaluated the biology of soil organisms, ex-situ; the hydrocarbonclastics and non-hydrocarbonclastics, following an exposure to spent engine oil. The result demonstrated that at low and moderate contaminations of 1.5 and 2.5% w/w, hydrocarbons reduced the microbial population from control, 1.28 x109 cfu, to 3.42 x108 and 3.06 x 108cfu on week one respectively. However, at increased contaminations of 3.5% w/w, hydrocarbons from large oil spills weaken microbial ability to degrade the added hydrocarbons as the prejudicial nature reduced the population to 1.62 x 108cfu on week one. Overall, across the weeks, there was insurgence of hydrocarbon-degrading organisms, the hydrocarbonclastics, which on the other hand induced a limitation in microbial diversity. The isolated hydrocarbonclastic microorganisms in the descending order of their biodegradation potentials are: Pseudomonas aeruginosa, Arthrobacter, Alealigena, Corynebacter, Flavo-bacterium, Archromobacter, Micrococcus, Norcardia and Myco-bacterium. Thus within the ecosystem they devised metabolic diversity with increased catabolic properties primarily aimed at biodegrading the xenobiotics; making them hydrocarbonclastic organisms.

Authors: M Ebulue, M.
Published: June 2022

Assessment of the level of contaminations from possible impact of crude oil on soil ecosystem is imperative for the determination of environmental acceptability. This study investigated this impact ex-situ using a culture-dependent approach to evaluate the total microbial counts; physicochemical tools to determine the cation exchange capacity (CEC), metal leachates, exchangeable bases (Mg, Ca, Na and K), pH, total petroleum hydrocarbon (TPH) and the overall effects on plants as indices of toxicity. The experiment demonstrated that at 1.5 – 3.5% contamination across days-zero to -28, there was a significant (p<0.05) increase in total petroleum hydrocarbon (TPH) from 0.03 ± 0.00 to 0.07 ± 0.00 with increase in acidity from pH 5.2 ± 0.00 to 4.0 ± 0.00 and a reduction in cation exchange capacity (CEC) from 0.82 ± 0.05 to 0.70 ± 0.11mEq and exchangeable bases with an augmented increase in phytotoxic elements and metal leachates. A reduction in microbial biomass from control, 1.30 x 109, to 3.6 x 108 cfu on week one as contamination increased and induction of hydrocarbonclastic organisms thereafter across weeks two and four, 3.88 x 108 and 4.40 x 108 cfu respectively was an indication of a reduction in microbial diversity. Ecosystem dynamics and mineralization were impaired and disrupted and the entire soil biochemistry altered with adverse effects on plant health.

Diabetes-induced Cataract is a major concern regarding the cause of blindness in developed and developing countries. Recent basic research studies have emphasized the role of the polyol pathway in the initiation of the disease process. Diabetes induced cataract is also referred to as “Diabetic cataract”. Demographic studies have certainly enhanced our knowledge concerning an association between diabetes and cataract formation and have defined the risk factors for the development of cataracts. Diabetic patients also have a higher risk of complications after phacoemulsification cataract surgery as compared to non-diabetic people. Aldose-reductase inhibitors and antioxidants have been proven beneficial in the prevention or treatment of this sight-threatening condition in in vitro experimental studies. Aldose reductase inhibitors have a vital importance in the treatment and prevention of diabetic complications. Nowadays, use of natural, herbal, and naturopathic medications has increased, as they have more therapeutic potential and lesser side effects as compared to the allopathic and ayurvedic medications. This research work provides an insight into herbal standardized extract and its ocular formulation development, Eyedrop, as an easy, sterile, safe, and alternative to phacoemulsification. Development of eyedrop as an ocular formulation and its standardization with an in vitro evaluation of the herbal extract for the prevention as well as treatment of Diabetic cataract.
