The difficulty of getting a job that is in accordance with the interests and specialization of a worker, as well as the difficulty of the company getting a worker who suits the needs of the company causes the mushrooming of consulting firms or labor providers in Indonesia today. With the increasing number of companies providing labor, of course the competitiveness of the business industry in the human resources is increasingly high. So it needs to be analyzed to determine the right business strategy, such as determining the company's promotion goals. One of them is analyzing the segmentation of customers who have worked together. This research successfully modeled customer segmentation based on data mining clustering techniques using the K-Means data mining algorithm. The QRF (Quantity, Recency, Frequency) modeling process is analyzing the customer's behavior from the number of requests in each transaction carried out within a certain timeframe, as well as recency as the identification of the time span of the last transaction, as well as the number of transactions made within a certain time period. Researchers conducted a period of data for one year by analyzing customer activity in start-up providers of labor during 2019, on 86 active customers. Based on the analysis results obtained, customer segmentation in two clusters with QRF (Quantity, Recency, Frequency) modeling using Davies Bouldin Index (DBI) evaluation scored -0,482, while customer segmentation in three clusters using QRF (Quantity, Recency, Frequency) evaluation using Davies Bouldin Index (DBI) evaluation to obtain -0.469, and customer segmentation in four clusters with QRF (Quantity, Recency, Frequency) modeling using Davies BouldinIndex (DBI) evaluation to obtain -0,526.

Acetic acid detection in photovoltaic modules during ultraviolet irradiation and damp-heat combined tests
Authors: Asano Shota , Hamaoka Ryo , Jonai Sachiko , Hara Yukiko , Masuda Atsushi , Umeda Norihiro , Iwami Kentaro 
Published: February 2022

Abstract
In this study, we evaluated the acetic acid generation in photovoltaic (PV) modules during an accelerated reliability test that combines ultraviolet (UV) irradiation and damp-heat (DH) using tin film sensors. We employed a tin film to detect acetic acid through the change in optical reflectance due to the chemical reaction from metallic tin to transparent tin tetraacetate. The relative reflectance of the tin film sensors laminated in a PV module was measured and used as an indicator of acetic acid generated during the reliability test. Consequently, we achieved non-destructive detection of a small amount of acetic acid generated during the UV irradiation stage of the UV+DH combined test with high spatial and temporal resolution using tin film sensors.

Authors: Ogawa Yamato , Mayuzumi Satsuki , Miyayama Takumi , Usui Hiroaki 
Published: February 2022

Abstract
Thin films of 3-methacryloyloxypropylheptaisobutyl-T8-silsesquioxane (BuPOSSMA) were prepared by an electron-assisted (e-assist) deposition method. The film deposited by the conventional vapor deposition without the e-assist had a polycrystalline structure with a rough surface, whereas the e-assist deposition produced amorphous polymer thin films with a smooth surface. The deposited films were electrically insulating with a breakdown strength higher than 2 × 106 V cm−1. The polymerization of BuPOSSMA resulted in a decrease in the dielectric constant of the film. It was found that the deposition-polymerization achieved by the e-assist is effective in improving the thermal stability of the insulating and dielectric characteristics.
Liquid metal printed electronics towards ubiquitous electrical engineering
Authors: Chen Sen , Liu Jing 
Published: February 2022

Abstract
Conventional electronic manufacturers are generally not easily accessible due to complicated procedures, time, material and energy consuming, and may generate potential pollution to the environment. From an alternative, liquid metal printed electronics to quickly fabricate electronic circuits and functional devices were proposed a decade before. To promote the further development and application of liquid metal printed electronics, this review aims to summarize and analyze the progress of liquid metal printed electronics from three aspects, namely electronic inks, printing technology and applications. Then, we will discuss the challenges and opportunities for further development of liquid metal printed electronics from several aspects including material modification, technological innovation, equipment upgrading and potential applications. It is expected that liquid metal printed electronics allow one to make electronics at anytime, anywhere at low cost which indicates the coming of a new era of ubiquitous electrical engineering.

Abstract
In a previous study, we successfully obtained a large-diameter, low-dislocation-density GaN wafer using the flux-film-coated and the multi-point-seed technique (FFC-MPST). As a production cost-cutting strategy, we are aiming to reuse a part of grown GaN crystals and produce thicker films by the Na-flux regrowth. Recently, however, it was found that threading dislocations (TDs) were generated at the growth interface in homoepitaxial growth of GaN crystals by the Na-flux method. In this study, we found that rapid growth in the regrowth contributes to the formation of inclusions causing the generation of TDs at the regrowth interface. Hence, we succeeded in suppressing the generation of TDs by a low growth rate, realized by a low-pressure condition at an initial growth stage. These findings are valuable for the productivity enhancement of high-quality GaN wafers and help the widespread of GaN-based devices.

"IT-librarians": searching ways of innovation, labor mobility, or change of professional principles development?
Authors: Matvienko Oksana , Tsyvin Michael 
Published: February 2022

The article is devoted to identifying trends in scientific thought regarding the role and functions of the library in the digital society, as well as the considerations of domestic scientists regarding IT technologies in library education.
The views of national scholars on the content of the IT education of librarians are analyzed, the proposals on their preparation with the focus on future activity not in libraries and possible functions of the library as a "forge frame" for IT companies are emphasized.
The term "Cybrarians" used in foreign publications is emphasized.
It is concluded that the desire to provide the future library specialist with all the digital competences in full, which in practice is often accompanied by unsystematic, formal filling of the curricula of IT disciplines without a scientifically methodically justified level and depth of their presentation to students.
The current situation is characterized by the spontaneity of innovations, which are justified by the terms "innovation", "mobility of the specialist in the labor market" (outside library institutions), theses about the "archaic" of the library and the unpopularity of the profession among modern entrants.
The content of the librarian's IT education in modern conditions should be aimed at the free use of modern technologies, the ability to set tasks before the IT specialists and the systematic formation of social and pedagogical communicative competences in the field of IT technologies, which corresponds to the axiology of library activity and the needs of the state and the individual overcoming digital inequality.

Authors: KARA Özgür , OLUKLU Deniz , SAHİN Dilek 
Published: February 2022

Objective: To estimate the birth weight by examining the fasting glucose, 1st -hour postprandial glucose, and Hemoglobin A1c levels in pregnant women diagnosed with pregestational diabetes mellitus (PGDM) and gestational diabetes mellitus (GDM) at 28th and 32nd gestational weeks.
Methods: A total of 105 pregnant women diagnosed with 66 GDM, 39 PGDM (7 of type 1 DM and 32 of type 2 DM) were included in our study. All participants' age, obstetric histories, pre-pregnancy body mass index (BMI), gestational weight gain (GWG), gestational weeks, fasting and 1st-hour postprandial glucose, HbA1c, gestational week at delivery, newborn weight and percentile, and 1st and 5th minute Apgar score were noted.
Results: Fasting glucose, 1st-hour postprandial glucose, and HbA1c values measured at 28th and 32nd gestational weeks were significantly higher in the PGDM group compared to the GDM group, and the GWG and pre-pregnancy BMI values were similar. ROC curve analysis was used to assess for fasting glucose, 1st-hour postprandial glucose, and GWG predicting large for gestational age (LGA) in the GDM group (AUC: 0.663, %95 CI [0,526, 0,800], AUC: 0.678, %95 CI [0,540, 0,816], AUC: 0.677, %95 CI [0,548, 0,805], respectively). Also, determined to fasting glucose, 1st-hour postprandial glucose, and HbA1c predicting LGA in the PGDM group (AUC: 0.889, %95 CI [0,782, 0,996], AUC: 0.893, %95 CI [0,737, 1,000], AUC: 0.931, %95 CI [0,807, 1,000], respectively).
Conclusion: Glycemic control is critical in pregnant women with PGDM and GDM. The risk of LGA may be reduced by closely monitoring HbA1c and postprandial glucose in PGDM and postprandial glucose and GWG in GDM. By minimizing fetal overgrowth, the risk of childhood obesity and metabolic syndrome that may develop in the long term may be reduced.
Connecting Chromospheric Condensation Signatures to Reconnection-driven Heating Rates in an Observed Flare
Authors: Ashfield IV William H. , Longcope Dana W. , Zhu Chunming , Qiu Jiong 
Published: February 2022

Abstract
Observations of solar flare reconnection at very high spatial and temporal resolution can be made indirectly at the footpoints of reconnected loops into which flare energy is deposited. The response of the lower atmosphere to this energy input includes a downward-propagating shock called chromospheric condensation, which can be observed in the UV and visible. In order to characterize reconnection using high-resolution observations of this response, one must develop a quantitative relationship between the two. Such a relation was recently developed, and here we test it on observations of chromospheric condensation in a single footpoint from a flare ribbon of the X1.0 flare on 2014 October 25 (SOL2014-10-25T16:56:36). Measurements taken of Si iv 1402.77 Å emission spectra using the Interface Region Imaging Spectrograph (IRIS) in a single pixel show the redshifted component undergoing characteristic condensation evolution. We apply the technique called the Ultraviolet Footpoint Calorimeter to infer energy deposition into one footpoint. This energy profile, persisting much longer than the observed condensation, is input into a one-dimensional, hydrodynamic simulation to compute the chromospheric response, which contains a very brief condensation episode. From this simulation, we synthesize Si iv spectra and compute the time-evolving Doppler velocity. The synthetic velocity evolution is found to compare reasonably well with the IRIS observation, thus corroborating our reconnection–condensation relationship. The exercise reveals that the chromospheric condensation characterizes a particular portion of the reconnection energy release rather than its entirety, and that the timescale of condensation does not necessarily reflect the timescale of energy input.

Abstract
Stellar streams from globular clusters (GCs) offer constraints on the nature of dark matter and have been used to explore the dark matter halo structure and substructure of our Galaxy. Detection of GC streams in other galaxies would broaden this endeavor to a cosmological context, yet no such streams have been detected to date. To enable such exploration, we develop the Hough Stream Spotter (HSS), and apply it to the Pan-Andromeda Archaeological Survey (PAndAS) photometric data of resolved stars in M31's stellar halo. We first demonstrate that our code can re-discover known dwarf streams in M31. We then use the HSS to blindly identify 27 linear GC stream-like structures in the PAndAS data. For each HSS GC stream candidate, we investigate the morphologies of the streams and the colors and magnitudes of all stars in the candidate streams. We find that the five most significant detections show a stronger signal along the red giant branch in color–magnitude diagrams than spurious non-stream detections. Lastly, we demonstrate that the HSS will easily detect globular cluster streams in future Nancy Grace Roman Space Telescope data of nearby galaxies. This has the potential to open up a new discovery space for GC stream studies, GC stream gap searches, and for GC stream-based constraints on the nature of dark matter.
The “Singular” Behavior of the Solar Wind Scaling Features during Parker Solar Probe–BepiColombo Radial Alignment

Published: February 2022

Abstract
At the end of 2020 September, the Parker Solar Probe (PSP) and BepiColombo were radially aligned: PSP was orbiting near 0.17 au and BepiColombo near 0.6 au. This geometry is of particular interest for investigating the evolution of solar wind properties at different heliocentric distances by observing the same solar wind plasma parcels. In this work, we use the magnetic field observations from both spacecraft to characterize both the topology of the magnetic field at different heliocentric distances (scalings, high-order statistics, and multifractal features) and its evolution when moving from near-Sun to far-Sun locations. We observe a breakdown of the statistical self-similar nature of the solar wind plasma with an increase in the efficiency of the nonlinear energy cascade mechanism when moving away from the Sun. We find a complex organization of large field gradients to dissipate the excess of kinetic energy across the inertial range near the Sun, whereas the topological organization of small fluctuations is still primarily responsible for the energy transfer rate at 0.6 au. These results provide, for the first time, evidence of the different roles of dissipation mechanisms near and far away from the Sun.
Les neurones miroirs, hommes à tout faire des neurosciences : analyse critique des limites méthodologiques et théoriques
Authors: Decroix Jeremy , Rossetti Yves , Quesque François 
Published: February 2022

Les neurones miroirs et les principales théories associées ont occupé et occupent encore une place importante dans les neurosciences et la psychologie, s’immisçant même très fréquemment dans de nombreux domaines non scientifiques. Malgré d’importantes limites, ils persistent à inspirer les chercheurs qui leur trouvent des implications potentielles dans tous les champs de la cognition humaine. Le présent article se propose de faire un point sur les principales limites méthodologiques et théoriques qui ont été formulées à l’encontre des neurones miroirs. Dans une première partie, nous montrons qu’il n’existe presque aucune méthode pour étudier sans ambiguïté les neurones miroirs chez l’être humain. Dans une deuxième partie, nous montrons que le mécanisme miroir, à travers la simulation motrice, se heurte à des limites théoriques irrésolubles, et qu’il ne permet pas de rendre compte de la complexité des phénomènes auquel il prétend répondre. Nous concluons sur le fait que les neurones miroirs gagneraient à perdre leur attribut « miroir ».
