Revitalising career counseling for sustainable decent work and decent lives: From personality traits to life project reflexivity for well-being
Authors: Di Fabio Annamaria , Svicher Andrea , Palazzeschi Letizia , Gori Alessio
Published: June 2022

The context of contemporary work scenarios features constant change and innovation in the field of information and communication technologies, which result in frequent work transitions and job insecurity. Such circumstances are highly threatening to the well-being of workers. Moreover, the instability and precariousness of the labour market are aggravated by the current crisis of the COVID-19 pandemic. Individuals are facing increased critical life and professional challenges and are being asked to take personal responsibility for the direction of their personal and work lives. In this complex context, career counseling needs to be revitalised in strength-based prevention perspectives. Life Project Reflexivity (LPR) addresses future professional and life plans and represents a critical construct for career counseling. The present study among Italian university students in transition to the labour market analysed the relationships between LPR and well-being while controlling for the ‘Big Five’ personality traits. The Big Five Questionnaire, the Life Project Reflexivity Scale and measures of both hedonic and eudaimonic well-being were administered to 278 university students of the University of Florence. LPR and its dimensions of authenticity, no acquiescence and clarity/projectuality explained the incremental variance beyond personality traits with respect to both hedonic and eudaimonic well-being, with specific reference to meaning in life. Among the three dimensions of LPR, authenticity was the most promising in this study. These results offered new perspectives for career counseling by supporting a strength-based prevention process for constructing sustainable decent work and life.

TAFSIR KESETARAAN DALAM AL-QUR’AN: Telaah Zaitunah Subhan atas Term Nafs Wahidah
Authors: Basid Abd. , Miskiyah Ruqayyah
Published: June 2022

Diskusi tentang kesetaraan antara pria dan wanita dari zaman pra-Islam hingga Islam datang terus menjadi perbicangan serius. Dalam Islam, salah satu yang memantik diskusi tersebut adalah kajian atas kata nafs wahidah perihal asal usul penciptaan wanita, yang tersebut dalam QS. al-Nisa’ (4): 1, QS. al-Nisa’ (4): 41, QS. al-A’raf (7): 189, QS. al-Nahl (16): 72, QS. al-Rum (30): 21, QS. al-Zumar (39): 6, dan QS. al-Syura (42): 11. Beberapa ayat-ayat tentang nafs wahidah ini yang dalam pembahasan artikel ini disebut dengan “ayat-ayat kesetaraan” karena menjadi dalil kesetaraan gender antara pria dan wanita. Dari kata nafs wahidah, mufassir klasik cenderung memaknainya bahwa wanita diciptakan dari tulang rusuk pria yang pada akhirnya berimplikasi pada ketimpangan gender. Seiring berjalannya waktu, mufassir dan tokoh modern menggugat terhadap penafsiran mufassir klasik, termasuk di antaranya Zaitunah Subhan yang menjadi fokus penelitian ini. Akan hal itu, penelitian ini ingin menjawab sebuah pertanyaan; bagaimana penafsiran Zaitunah Subhan atas ayat-ayat kesetaraan dalam al-Qur’an?. sebagai langkah metodis, artikel ini menggunakan metode analisis diskriptif dengan bertumpu pada kajian pustaka (library reseach). Pada akhirnya, penelitian ini menghasilkan sebuah kesimpulan bahwa Zaitunah Subhan memaknai kata nafs wahidah bukanlah Adam (pria) tapi lebih tepatnya adalah “diri yang satu” di mana Hawa (wanita) juga diciptakan darinya. Tidak ada perbedaan antara keduanya kecuali tingkat ketakwaan yang dimilikinya.

Covid-19: Catalyst for a comprehensive law to combat potential pandemics in India
Authors: Mishra Abhishek , Naik Bijaya Nanda , Kumar Sanjay , Agarwal Neeraj
Published: June 2022

Despite the relative decline in communicable diseases, India witnesses hundreds of outbreaks every year. Including the current Covid-19 pandemic, India has suffered through several major pandemics and large-scale epidemics since 1900s. However, the response to most of the epidemics has been inadequate. The Epidemic Diseases Act, enacted in 1897 (EDA 1897), has been in action since and is based on the science and the socio-political environment of the country in the nineteenth century. India has several legal mechanisms to help contain and control the spread of epidemics, but on different platforms. There has been a paradigm shift in the socio-political milieu as well as scientific advancements in the prevention and control of epidemics. The century-old EDA 1897 has not been effective in containing and controlling such epidemics/pandemics, as has been witnessed during the ongoing Covid-19 pandemic. Hence, it needs to be revised to define an appropriate structural scalar chain, provide clear-cut and unambiguous terms/definitions and guidelines, delineate ethics and human rights, determine the duties and responsibilities of the affected population/community, determine the role of the private health sector, and provide for appropriate punitive measures to deter repeated violations.
Fault Interpretation Based on Similarity and Curvature Attributes in F3 Netherlands
Authors: Saragih Nadea Arie , Farid Faizar , Juventa Juventa
Published: June 2022

F3 Southern North Sea Netherlands Basin field is an oil and gas field that has a complex fault structure and stratigraphy due to compressional tectonic movements during the Late Cretaceous and Tertiary eras. Information on the presence of faults can act as a trap or migration which then greatly affects oil and gas production and the injection process. A seismic attribute analysis of similarity and curvature was used to interpret the presence of fault structures to obtain information on the presence of subsurface faults in the F3 Netherlands field. The interpretation of the similarity attribute calculation results shows that the faults are marked with a minimum similarity value of 0.77, 0.68, and 0.66 at the time slices Z = 400ms, 1700ms, and 1800ms. The maximum value of most post-positive curvature represents the presence of an ascending fault block and the maximum value of the most negative curvature represents the presence of a descending fault block at the same time incision. Based on the similarity and curvature attribute calculations, it can be interpreted that the major faults in Top Zechstein to Upper Pliocene and the presence of successive faults on Top Zechstein to Base Lower Cretaceous are faults due to the formation of the Zechstein salt dome intrusion

Authors: Supardi Nurhikmah , Rahmawati Savira Aulia
Published: June 2022

The Sulawesi Molasa Formation is mostly composed of clastic and carbonate sediments which are widely distributed on the island of Sulawesi. Research on the Sulawesi Molasa Formation has been carried out by several researchers. However, there has been no detailed research on limestone biostratigraphy in the Donggala area, so it is very important to do it. This study aims to analyze the age and depositional environment of the Sulawesi Molasa Formation limestone based on the content of large foraminifera. The method used in data collection is measuring section. Field data collection was carried out by stratigraphic measurements including lithology identification, thickness and rock sampling. Laboratory observations were carried out using a polarizing microscope to observe a thin section of rock to determine the species of large foraminifera, their mineral and organic compositions. From the results of field observations found four types of lithology, namely wackestone, packstone, grainstone and floatstone. Based on the observation of large foraminifera fossils in a thin section of limestone in the study area, there are 24 species of large foraminifera identified. Among them, there are four index fossils, namely Miogypsinoides dehaarti (van der Vlerk), Paleomiogypsina bononensis (Matsumaru), Miogypsina sp, (Vaughan), Paleomiogypsina sp, and Miogypsinella sp, (Aquitanian). Based on age withdrawal and description of large foraminifera fossils, it is known that the limestones of the study area are Early Miocene-Middle Miocene age with the depositional environment in the lagoon zone to the forereef shelf

Hybrid seed production is the important key in the commercialization and development of hybrid rice. The successful of hybrid rice development through the exploitation of heterosis phenomenon in China encouraged other countries including Indonesia to develop hybrid rice. Research conducted at Indonesian Center for Rice Research (ICRR) indicated that the development of hybrid rice technology offered opportunities for increasing rice yields by 15-20% compared to inbred varieties. The high cost of hybrid seed is one of the constraints in the adoption of hybrid rice technology. This is primarily attributed to the low hybrid seed yield which is around 1-1.5 t/ha. This article introduces the results of research and development especially in hybrid rice seed production based on genetic of parental lines of hybrid and its field management. The constraints and opportunities of hybrid seed industry in Indonesia also discussed in this article.

ABSTRAK

Kopi, karet, dan kakao merupakan komoditas penting perkebunan di Indonesia. Dalam budidayanya, rayap merupakan salah satu hama penting yang menjadi kendala pada tanaman perkebunan dan dapat merugikan secara ekonomis Tulisan ini mengulas rayap sebagai hama pada tanaman kopi, karet, dan kakao, serta perkembangan pengendalian dan strategi pengelolaannya. Beberapa pendukung keberadaan rayap pada suatu areal perkebunan adalah cukup tersedianya bahan pada media tanam dan di sekitar tanaman. Gejala kerusakan yang disebabkan oleh rayap berupa gerekan pada batang dapat menyebabkan terganggunya tanaman yang berdampak pada terhambatnya pertumbuhan dan bahkan kematian tanaman. Pada perbenihan, serangan rayap sering menyebabkan kematian bibit. Teknik pengelolaan penting dalam pengendalian rayap secara kultur teknis adalah dengan menggunakan media pembibitan yang rendah bahan dan melakukan sanitasi lahan. Selain itu, penggunaan pestisida kimiawi ternyata masih menjadi andalan saat ini, sehingga dapat mencegah investasi rayap pada wilayah perkebunan dan dapat menekan tingkat kerusakan sebesar 70-100%. Namun, demikian untuk pengelolaan hama mendukung pertanian modern berkelanjutan, pengendalian rayap yang ramah lingkungan dengan basis pengendalian hayati dan nabati, yang saat ini telah banyak didukung hasil penelitian yang memadai, perlu dikembangkan dan diimplementasikan secara nyata dengan dukungan seluruh pihak.

ABSTRACT

Coffee, rubber, and cocoa are leading plantation commodities in Indonesia. In its cultivation, termites are one of the important pests that are a constraint on plantation crops and can be economically detrimental. One factor that supports the termites' activity in a plantation area is the availability of organic material. Symptoms of damage caused by termites are brittle stems that disrupt plants which cause stunted growth and even death of plants. The damage becomes serious in the stage of seedlings. Low organic matter media usage and field sanitation can reduce the termites' population. In addition, chemical pesticides are still a mainstay currently, so they can prevent termite investment in plantation areas and reduce damage levels by 70-100%. However, for pest management to support sustainable modern agriculture, environmentally friendly termite control based on biological and botanical control, which is completed by adequate research, needs to be developed and implemented in real terms with the support of all stakeholders.
BIOLOGICAL AGENTS AND THEIR ROLE TO INCREASE PLANT ESSENTIAL OIL UNDER WATER STRESS Agen Hayati dan Peranannya dalam Meningkatkan Minyak Atsiri Tanaman pada Kondisi Cekaman Air

Published: June 2022

Essential oils are plant natural products resulting from secondary metabolites used for raw materials of various industries such as perfumery, preservative, cosmetics, and pesticide. The major problem of essential oil plants cultivation is the low essential oil content. Enhancing essential oil content is one of the main focuses in developing essential oil plants which can be reached by water management. Growth and yield reduction and changes in some physiological reactions are the responses of a plant toward water supply shortage (water stress). Water stress triggers elicitors and some signal molecules produced for secondary metabolites resulting in higher essential oil percentages. However, it would also decrease essential oil yield following lower biomass production. Some microorganisms can produce phytohormone and enhance nutrient uptake allowing the plant to cope under water stress condition.  Understanding how the environment affected plant secondary metabolite (especially essential oil), as well as microorganism roles for crop production, will provide proper cultivation technology to increase plant essential oil content and oil yield. This review aimed to analyze the potential use of some biological agents to alleviate the negative effect of water stress on essential oil plants.

ABSTRAK

Minyak atsiri merupakan produk alami tanaman dari hasil metabolisme sekunder yang digunakan sebagai bahan baku berbagai industri seperti parfum, antiseptik, kosmetik, dan pestisida. Budidaya tanaman  minyak atsiri menghadapi kendala seperti rendahnya kandungan minyak yang dihasilkan. Pertumbuhan dan penurunan hasil serta perubahan pada beberapa reaksi fisiologis merupakan respon tanaman terhadap cekaman air. Cekaman air memicu produksi elisitor dan beberapa molekul sinyal pada metabolit sekunder sehingga dapat menghasilkan minyak atsiri yang lebih tinggi, akan tetapi tidak diikuti dengan peningkatan produksi biomassa sehingga produksi minyak atsiri tidak cukup tinggi. Beberapa mikroorganisme mampu menghasilkan fitohormon dan meningkatkan serapan hara yang memungkinkan tanaman dapat bertahan pada kondisi cekaman air. Pemahaman bagaimana lingkungan dapat mempengaruhi metabolit sekunder dari tanaman (khususnya minyak atsiri), serta peran mikroorganisme terhadap produksi tanaman, akan menghasilkan teknologi budidaya yang sesuai untuk meningkatkan kandungan dan hasil minyak atsiri suatu tanaman.  Review ini bertujuan menganalisa potensi penggunaan beberapa jenis agens hayati untuk mengurangi dampak negatif dari cekaman air pada tanaman penghasil minyak atsiri.
Extraction of high inverted mesiodens via the labial, palatal and subperiostal intranasal approach：A clinical prospective study

Published: June 2022

Background As the potential risks of the development of the adjacent incisors and jaws, mesiodens, especially inverted mesiodens, should be prophylactically extracted in mixed or early permanent dentition. However, because of the limit of small clinical data, there is relatively inadequate and lacks systematic, comprehensive understanding on minimizing operation injury for high inverted mesiodens. The aim of this study is to provide reliable support for the choice of extraction of high inverted mesiodens, and minimize the operation injury for patients.Methods Thirty patients were randomly divided into three groups according to three different surgical designs in the extraction of high inverted mesiodens. The operation statistics, life quality of postoperative patients, and the operative injury/recovery were compared and analyzed. The laser Doppler blood flowmetry, laser speckle contrast imaging, and electric pulp testing were explored to detect the postoperative pulp and gingiva blood supply of adjacent teeth.Results For the clinician's primary concerns, the surgical time, the volume of osteotomy, and the amount of bleeding in the labial approach group and intranasal approach group were significantly less than that in the palatal approach group (p<0.05). However, from the patient's perspective, the postoperative swelling and pain in the labial approach were far more than that in the intranasal approach group (p<0.05), with unsurprisingly lower satisfaction (p<0.05). Under excellent surgical operation，there were no significant differences in pulp and gingival blood supply of adjacent teeth and jaw development (p>0.05).Trauma was manageable in all patients.Conclusions With precisive operation, maxillary inverted impacted mesiodens could be extracted by three methods, and the controlled trauma would not affect the development of teeth and jaw. Under the inclusion and exclusion criteria of this study, the extraction of mesiodens by the intranasal approach achieved a delicate balance between reducing surgical trauma and optimizing postoperative recovery, which was of concern and merited further study.Trial registration The study was approved by the Ethics Committee of Shanxi Medical University School and Hospital of Stomatology (2019SLL022), and retrospectively registered at chictr.org.cn (ChiCTR2100054777). All patients provide written informed consent before participating in treatment.
Clothing attribute recognition algorithm based on improved YOLOv4-Tiny
Authors: Gu Meihua , Liu Jie , Hua Wei
Published: June 2022

Aiming at the problem of low accuracy of clothing attribute recognition caused by factors such as scale, occlusion and beyond the boundary, a novel clothing attribute recognition algorithm based on improved YOLOv4-Tiny is proposed in this paper. YOLOv4-Tiny is used as the basic model, firstly, the multi-scale feature extraction module Res2Net is adopted to optimize the backbone network, the receptive field size of each layer of the network is increased, and more abundant fine-grained multi-scale clothing feature information is extracted. Then, the three feature layers of the output of feature extraction network are up-sampled, and the high-level semantic features and shallow features are fused to obtain rich shallow fine-grained feature information. Finally, K-Means clustering algorithm is employed to optimize the anchor box parameters to obtain the anchor box that is more compatible with the clothing object, and to improve the integrating degree between the clothing attribute characteristics and the network. The experimental results show that the proposed method can significantly improve the accuracy of clothing attribute recognition for different scale proportions, occlusion degrees and out-of-bounds degrees, and its mean average prediction(mAP) is improved by 6.75% compared with the original model.
No, an oral presentation is not just something you prepare at home! Elementary teachers’ practices supporting preparation of oral presentations
Authors: Stordeur Marie-France , Nils Frédéric , Colognesi Stéphane
Published: June 2022

In elementary school, oral presentations are among teachers’ favorite activities. From the pupil’s perspective, this activity can have a major impact, as the skills it calls for will prove useful later throughout his/her career and life. While instruction for the presentation generally happens in class, the same is not true for the preparatory work, which is mostly carried out at home with or without parental support, thus creating inequalities between students (Sénéchal, 2017). However, teacher support is essential to help elementary school students prepare their oral presentation.

Our research question is: what kinds of support do teachers offer to students to help them prepare oral presentations? To answer this question, we interviewed 16 teachers from the French-speaking part of Belgium who ask their students to make oral presentations and who say they offer support before the presentation. Their declared practices show a wide variety of types of accompanying support. The practical implications of our study relate to progressive teaching of a complex task, rebalance between time devoted to oral and to written preparation, attention to the speaker and the audience, collection of artifacts, introduction of training modules for teachers, and best practices to be highlighted.
Control theory-based data assimilation for open channel hydraulic models: tuning PID controllers using multi-objective optimization
Authors: Milašinović Miloš , Prodanović Dušan , Stanić Miloš , Zindović Budo , Stojanović Boban , Milivojević Nikola
Published: June 2022

Reliable water resources management requires decision support tools to successfully forecast hydraulic data (stage and flow hydrographs). Even though data-driven methods are nowadays trendy to apply, they still fail to provide reliable forecasts during extreme periods due to a lack of training data. Therefore, model-driven forecasting is still needed. However, the model-driven forecasting approach is affected by numerous uncertainties in initial and boundary conditions. To improve the real-time model's operation, it can be regularly updated using measured data in the data assimilation (DA) procedure. Widely used DA techniques are computationally expensive, which reduce their real-time applications. Previous research shows that tailor-made, time-efficient DA methods based on the control theory could be used instead. This paper presents further insights into the control theory-based DA for 1D hydraulic models. This method uses Proportional–Integrative–Derivative (PID) controllers to assimilate computed water levels and observed data. This paper describes the two-stage PID controllers’ tuning procedure. Multi-objective optimization by Nondominated Sorting Genetic Algorithm II (NSGA-II) was used to determine optimal parameters for PID controllers. The proposed tuning procedure is tested on a hydraulic model used as a decision support tool for the transboundary Iron Gate 1 hydropower system on the Danube River, showing that the average discrepancy between modeled and observed water levels can be less than 0.05 m for more than 97% of assimilation window.

Covering 60 years (1955–2016), this paper analyzed the spatio-temporal trends of daily annual and seasonal means of precipitation, temperature, and extreme climate indices. The long-term decadal change analysis was carried out in two timeframes for consecutive analysis periods of 1955–1985 and 1986–2016 to capture the relative regional variations. The trends were evaluated using the modified Mann-Kendall (MMK) and Sen's slope (SS) statistical tests. The pattern visualized on maps was assessed for regions and districts located in the four states of the Indian Himalayan Region. The results revealed significant increases in the annual mean precipitation (1.61 mm/year) and temperature (0.07°/year) in Uttarakhand, followed by Himachal Pradesh from 1986 to 2016. The seasonal monsoonal precipitation showed a significantly increasing trend in parts of Himachal Pradesh, followed by Uttarakhand. The maximum and minimum temperature values increased in all the states, increasing temperature extremes. Significant trends in climate indices were observed in the second period of analysis. A rise of 0.02 °C/year in temperature extremes was observed in Uttarakhand. There is a progressive rise in precipitation indices, specifically in Uttarakhand (0.49 mm/year), and a drop in cold extremes with an increase of hot events in most states. The spatio-temporal variations were driven by multiple dominant mechanisms like orography, anthropogenic activities, land-use changes, teleconnections, and the emission of greenhouse gases. This study highlights the influence of climate change in different divisions of the Himalayas.
Optimization of cropping pattern under seasonal fluctuations of surface water using multistage stochastic programming

Given rapid socio-economic development, increasing food demand and decreasing available resources, the challenge of seasonal fluctuations of surface water has become a major problem in the agricultural sector, causing a change in consumption from surface water to groundwater resources and reduction of farmers' income. Therefore, optimal programming of the cropping pattern is necessary to handle such challenges. To accomplish this aim, a model of irrigation water allocation was developed based on cropping pattern using multistage stochastic programming in accordance with surface water supply fluctuations. In this model, different stochastic states were considered for all irrigation seasons in the irrigation network of the Jiroft plain in Kerman Province, Iran, which faces a severe shortage of surface water resources and the tendency of farmers to overuse groundwater resources. By solving a multistage stochastic model, it can be observed that, by utilizing an appropriate programming of the cropping pattern, more benefits for the farmers could be realized in the conditions of available surface water fluctuations. The results also indicated that if the surface water released into the canals increased in the spring, the share of profitable high water consumption crops in the pattern will increase, which will strengthen farmers' profits and put pressure on groundwater resources. However, this could not be expected to lead to a significant reduction of groundwater resource consumption and a significant increase of cropping intensity. According to the results obtained, surface water resources cannot meet the water needs of the region, even by using optimal cropping patterns, and this has led to overuse of groundwater resources in this area. Finally, such planning can help adoption of desired policies for irrigation water management through the proper release of these resources.

Refrigerant is a crucial cooling component for the refrigeration cycle. In heavy equipment, the cooling system still relies on the R-134a unit with many weaknesses, including global warming effects and other air conditioning system problems. An alternative substitute for R-134a has been found, i.e., a hydrocarbon refrigerant or MC-134. This product has several advantages compared to R-134a, especially its environmentally friendly aspect. It does not contribute to the damage of the ozone layer and is completed with good physical characteristics and thermodynamic properties. Overall, it has better performance than R-134a, proven on the Nissan Evalia unit. This study aimed at testing heavy equipment, especially the D8R caterpillar unit because limited studies discuss heavy equipment regarding its MC-134performance. This research was carried out at the Petrosea Ltd workshop. The research was done through experimental methods. The first stage was retrofitting R-134a with MC-134 on the D8R caterpillar unit. The data collection was conducted ten times with an interval of 3 minutes. The second step WAS using MC-134 and taking the same data as the first step. The compressor work on the MC-134 increased by 145.96% compared to R-134a. The result of the study showed that the heat energy released by the condenser using MC-134 increased by 157.833%. 161.625% for the refrigeration effect, and 5.21% of The COP value, respectively, compared to R-134a.

This research aimed to design a tool that can reduce one type of waste on the production floor, namely excessive transportation in the form of a waste of transportation time. The design of the tool was carried out by inspecting to the details of the failures that occurred in the previous means of transportation. This development research implemented stopwatch time study method and failure mode and effect analysis to find out the value of the loss of transportation time and the types of failures that cause it. The sample of the transportation process time was taken by simple random sampling method from the intensity of the transportation process per month, based on the type of transportation process on the production floor of a textile company. Then the design of the tool was carried out using the morphological matrix method and weighted objectives table to create the design that fits the needs. The results show that the prediction of the amount of excessive transportation in the form of a waste of time can be minimized by 8,11 hours. Moreover, the new design tool also has a safe structure due to its attained maximum equivalent stress was 17.4 MPa which was smaller than the maximum yield stress of the ST37 material.

The 2019 corona virus (Covid-19) pandemic is a global problem for now. One way to deal with the spread of the corona virus is to maintain a distance of at least one meter and stay away from crowds. Therefore, a crowd detection warning system based on a deep convolutional neural network (deep CNN) was developed using CCTV. The development of this system was carried out using the NVIDIA Jetson Nano microcontroller as the computing hardware. Crowd object detection uses the OpenCV library, the YOLOv3-Tiny algorithm, and the euclidean distance method to calculate the distance between 'person' objects. Based on the tests carried out on function and performance, the results obtained that this crowd detection warning system can detect 'person' objects with an accuracy rate of 92.79. In addition, this system has also been able to detect several types of colors from objects so that warning messages can be given more specifically on the color of the clothes of the 'person' in the detected crowd.
