Authors: Jatmiko Ridhwan Ammar , Setyawan Imam
Published: September 2022

Penelitian ini dilaksanakan untuk mengetahui hubungan antara school well-being dengan prokrastinasi akademik pada siswa SMA Mardisiswa Semarang. Prokrastinasi Akademik adalah perilaku penundaan hal-hal yang berhubungan dengan kegiatan akademik yang dilakukan oleh siswa yang berhubungan dengan kegiatan akademik secara sengaja karena hal tersebut dianggap sulit atau tidak menyenangkan bagi siswa.  School well-being adalah penilaian subjektif dari siswa terhadap lingkungan sekolah terhadap kebutuhan dasar siswa ketika menjalankan kegiatan akademik maupun non-akademik di sekolah.  Populasi dalam penelitian ini berjumlah 211 orang siswa SMA Mardisiswa, dengan sampel sebanyak 104 orang siswa yang diambil melalui teknik cluster random sampling. Alat ukur yang digunakan dalam penelitian ini adalah Skala School Well-Being (26 aitem, α = 0,893) dan Skala Prokrastinasi Akademik (23 aitem, α = 0,863). Analisis data dilakukan dengan analisis Spearman’s Rho, menunjukkan adanya hubungan negatif yang signifikan antara school well-being dengan prokrastinasi akademik pada siswa SMA Mardisiwa Semarang (rxy = -0,498 dan p = 0,000). Hubungan yang negatif memiliki makna bahwa semakin tinggi school well-being maka semakin rendah prokrastinasi akademik. Saran bagi subjek yaitu subjek sebaiknya dapat mengatur waktu dengan baik untuk mengerjakan tugas dan menyusun skala prioritas dalam mengerjakan tugas.

The economic growth of an area is closely related to population growth. The increasing population growth has implications for the level of economic activity of the people. Economic activity in an area can spread or agglomerate at certain points. Its growth can also be organic as is the case in the Trading Area in Muntilan District. This area extends along the primary arterial road or Ribbon Development along Jogja-Magelang Streets which connects Magelang City, Magelang Regency, Special Region of Yogyakarta. Trading areas are in the form of traditional markets, modern markets, shops, markets, squares, minimarkets, and others. Around this area, it is also equipped with various basic infrastructure and supporting facilities to meet the daily needs of society such as religious facilities, educational facilities, government facilities and public services, open space facilities, and important transportation objects. This is why it is interesting to examine the relationship between land use and the price of land offered in this trading area in Muntilan District. The method used in this study uses quantitative approaches with data obtained through observation, secondary surveys, and interviews through questionnaires. The analysis used is descriptive method and applies a superimpose process in the Geospatial Information System or Overlay. The results showed that the type of land use and the distance to the trading area determine variations in land prices.

Published: September 2022

Today's Hybrid Transactional and Analytical Processing (HTAP) systems, tackle the ever-growing data in combination with a mixture of transactional and analytical workloads. While optimizing for aspects such as data freshness and performance isolation, they build on the traditional data-to-code principle and may trigger massive cold data transfers that impair the overall performance and scalability. Firstly, in this paper we show that Near-Data Processing (NDP) naturally fits in the HTAP design space. Secondly, we propose an NDP database architecture, allowing transactionally consistent in-situ executions of analytical operations in HTAP settings. We evaluate the proposed architecture in state-of-the-art key/value-stores and multi-versioned DBMS. In contrast to traditional setups, our approach yields robust, resource- and cost-efficient performance.
Columnar formats for schemaless LSM-based document stores
Authors: Alkowaileet Wail Y. , Carey Michael J.
Published: September 2022

In the last decade, document store database systems have gained more traction for storing and querying large volumes of semi-structured data. However, the flexibility of the document stores' data models has limited their ability to store data in a column-major layout --- making them less performant for analytical workloads than column store relational databases. In this paper, we propose several techniques based on piggy-backing on Log-Structured Merge (LSM) tree events and tailored to document stores to store data in a columnar layout. We first extend the Dremel format, a popular on-disk columnar format for semi-structured data, to comply with document stores' flexible data model. We then introduce a new columnar layout for organizing and storing data in LSM-based storage. We also highlight the potential of using query compilation techniques for document stores, where values' types are known only at runtime. We have implemented and evaluated our techniques to measure their impact on storage, data ingestion, and query performance in Apache AsterixDB. Our experiments show significant performance gains, improving the query execution time by orders of magnitude while minimally impacting ingestion performance.
DESIRE

Published: September 2022

Similarity search finds similar objects for a given query object based on a certain similarity metric. Similarity search in metric spaces has attracted increasing attention, as the metric space can accommodate any type of data and support flexible distance metrics. However, a metric space only models a single data type with a specific similarity metric. In contrast, a multi-metric space combines multiple metric spaces to simultaneously model a variety of data types and a collection of associated similarity metrics. Thus, a multi-metric space is capable of performing similarity search over any combination of metric spaces. Many studies focus on indexing a single metric space, while only a few aims at indexing multi-metric space to accelerate similarity search. In this paper, we propose DESIRE, an efficient dynamic cluster-based forest index for similarity search in multi-metric spaces. DESIRE first selects high-quality centers to cluster objects into compact regions, and then employs B+-trees to effectively index distances between centers and corresponding objects. To support dynamic scenarios, efficient update strategies are developed. Further, we provide filtering techniques to accelerate similarity queries in multi-metric spaces. Extensive experiments on four real datasets demonstrate the superior efficiency and scalability of our proposed DESIRE compared with the state-of-the-art multi-metric space indexes.

Published: September 2022

Not only the vast applications but also the distinct features of time series data stimulate the booming growth of time series database management systems, such as Apache IoTDB, InfluxDB, OpenTSDB and so on. Almost all these systems employ columnar storage, with effective encoding of time series data. Given the distinct features of various time series data, it is not surprising that different encoding strategies may perform variously. In this study, we first summarize the features of time series data that may affect encoding performance, including scale, delta, repeat and increase. Then, we introduce the storage scheme of a typical time series database, Apache IoTDB, prescribing the limits to implementing encoding algorithms in the system. A qualitative analysis of encoding effectiveness regarding to various data features is then presented for the studied algorithms. To this end, we develop a benchmark for evaluating encoding algorithms, including a data generator regarding the aforesaid data features and several real-world datasets from our industrial partners. Finally, we present an extensive experimental evaluation using the benchmark. Remarkably, a quantitative analysis of encoding effectiveness regarding to various data features is conducted in Apache IoTDB.
Serving deep learning models with deduplication from relational databases
Authors: Zhou Lixi , Chen Jiaqing , Das Amitabh , Min Hong , Yu Lei , Zhao Ming , Zou Jia
Published: September 2022

Serving deep learning models from relational databases brings significant benefits. First, features extracted from databases do not need to be transferred to any decoupled deep learning systems for inferences, and thus the system management overhead can be significantly reduced. Second, in a relational database, data management along the storage hierarchy is fully integrated with query processing, and thus it can continue model serving even if the working set size exceeds the available memory. Applying model deduplication can greatly reduce the storage space, memory footprint, cache misses, and inference latency. However, existing data deduplication techniques are not applicable to the deep learning model serving applications in relational databases. They do not consider the impacts on model inference accuracy as well as the inconsistency between tensor blocks and database pages. This work proposed synergistic storage optimization techniques for duplication detection, page packing, and caching, to enhance database systems for model serving. Evaluation results show that our proposed techniques significantly improved the storage efficiency and the model inference latency, and outperformed existing deep learning frameworks in targeting scenarios.
Improving clinical performance of urine sediment analysis by implementation of intelligent verification criteria
Authors: Oyaert Matthijs , Maghari Sena , Speeckaert Marijn , Delanghe Joris
Published: September 2022

Objectives

Urinary test strip and sediment analysis integrated with intelligent verification criteria can help to select samples that need manual review. This study aimed to evaluate the improvement in the diagnostic performance of combined urinary test strip and urinary sediment analysis using intelligent verification criteria on the latest generation automated test strip and urinary fluoresce flow cytometry (UFFC) analysers.

Methods

Urine test strip and sediment analysis were performed using the Sysmex UC-3500 and UF-5000 (Kobe, Japan) on 828 urinary samples at the clinical laboratory of the Ghent University Hospital. The results were compared to manual microscopy using phase-contrast microscopy as a reference. After the application of the intelligent verification criteria, we determined whether the diagnostic performance of urine sediment analysis could be improved.

Results

Application of intelligent verification criteria resulted in an increase in specificity from 88.5 to 96.8% and from 88.2 to 94.9% for red blood cells and white blood cells, respectively. Implementing review rules for renal tubular epithelial cells and pathological casts increased the specificity from 66.7 to 74.2% and from 96.2 to 100.0%, respectively; and improved the diagnostic performance of urinary crystals and atypical cells.

Conclusions

The implementation of review rules improved the diagnostic performance of UFFC, thereby increasing the reliability and quality of urine sediment results.

Published: September 2022

Objectives

Quantitative protein mass-spectrometry (QPMS) in blood depends on tryptic digestion of proteins and subsequent measurement of representing peptides. Whether serum and plasma can be used interchangeably and whether in-vitro anticoagulants affect the recovery is unknown. In our laboratory serum samples are the preferred matrix for QPMS measurement of multiple apolipoproteins. In this study, we investigated the effect of different matrices on apolipoprotein quantification by mass spectrometry.

Methods

Blood samples were collected from 44 healthy donors in Beckton Dickinson blood tubes simultaneously for serum (with/without gel) and plasma (heparin, citrate or EDTA). Nine apolipoproteins were quantified according to standard operating procedure using value-assigned native serum calibrators for quantitation. Tryptic digestion kinetics were investigated in the different matrices by following formation of peptides for each apolipoprotein in time, up to 22 h.

Results

In citrate plasma recovery of apolipoproteins showed an overall reduction with a bias of −14.6%. For heparin plasma only −0.3% bias was found compared to serum, whereas for EDTA-plasma reduction was more pronounced (−5.3% bias) and variable with >14% reduction for peptides of apoA-I, A-II and C-III. Digestion kinetics revealed that especially slow forming peptides showed reduced formation in EDTA-plasma.

Conclusions

Plasma anticoagulants affect QPMS test results. Heparin plasma showed comparable results to serum. Reduced concentrations in citrate plasma can be explained by dilution, whereas reduced recovery in EDTA-plasma is dependent on altered proteolytic digestion efficiency. The results highlight the importance of a standardized pre-analytical phase for accurate QPMS applications in clinical chemistry.

This study explores the potential of the natural and cost-effective method of wound healing using Alternanthera sessilis by an in vitro study (using fibroblast L929 cells). Gram-positive bacteria Staphylococcus aureus shows a zone of inhibition of 20 mm at 60 µg concentration in the antibiogram profile against the zinc oxide nanoparticles (ZnONPs) wetted in fabrics synthesized from the Amaranthaceae family. Through characterization studies of the AS-ZnONPs, it was found that UV–visible spectra show a peak in the range of 350–460 nm, Fourier transform infrared spectroscopy spectra show a correlation peak in the range of 340–4,500 cm−1, scanning electron microscope with electron diffraction analysis results in a peak in the range of 7.8–9.4, and high-resolution transmission electron microscope, which exposes the morphological character (diamond shape in a black and white background), shows a peak at 200 nm. This work shows that the leaf extract of A. sessilis might support the ancient method of wound healing.
Desire, Consent and Misogyny in Post-medieval Adaptations of the Pelleas and Ettarde Story
Authors: Piercy Hannah
Published: September 2022

Pelleas and Ettarde may not be particularly well-known figures today, but in the nineteenth and twentieth centuries, following the publication of Alfred Lord Tennyson’s ‘Pelleas and Ettarre’ idyll, they were included or even centred in a number of Arthurian poems, plays and novels. This article explores the changing representations of Pelleas and Ettarde in post-medieval adaptations. Why do writers choose to retell and adapt this story? What kinds of intertextual connections are uncovered by focusing on these particular Arthurian afterlives? And how do modern writers reshape this story in response to contemporary perspectives on desire, consent and misogyny? Drawing upon examples from fourteen canonical and lesser-known works, this essay charts the post-medieval popularity of this story, which offers a valuable case study for understanding the changing representation of desire, consent and misogyny in modern Arthuriana.

Published: September 2022

The neutron capture cross section for the 164Dy(n,γ)165Dy reaction at 0.0372 eV energy was measured using the horizontal channel (Neutron Diffraction Facility) of Es-Salam nuclear research reactor in Birine-Algeria. The Neutron Activation Analysis (NAA) technique using 197Au(n,γ)198Au as reference reaction was adopted. The γ ray spectra for the Dy2O3 target powder and two thin gold foil were detected for the Germanium Hyper Pure coupled in the Genie 2000 data acquisition software. A resulting σ-value (2198.5 ± 94) b was measured for the thermal neutron cross section after correcting the thermal neutron self-shielding and γ attenuation effects. The measured value was then compared to the evaluated cross sections reported in two different libraries of neutron databases ENDF/B-VIII.0 and JEFF-3.3. The measured data at 0.0372 eV has been extrapolated to the energy of 0.0253 eV assuming 1/ν dependence in the thermal energy region and the result was compared with the fully measured values reported in the literature.

Es gibt immer mehr Literatur, in der die Bedeutung des digitalen Geschichtenerzählens in der Lebenswelt von Schüler:innen untersucht wird. Ausgehend von ambivalenten Narrativen in religionsbezogenen Erklärfilmen von MrWissen2go alias Mirko Drotschmann fragt vorliegender Beitrag nach Perspektiven einer aktuellen Didaktik der Kirchengeschichte: erstens bezüglich Kirchengeschichte als Zugang zur religiösen Deutung der Wirklichkeit in säkularer Zeit, zweitens hinsichtlich postkolonial revidierter Ansätze und drittens in Bezug auf die Herausforderungen der Digitalisierung. Insgesamt leistet dieser Aufsatz einen innovativen Beitrag zu neueren historiographischen und didaktischen Debatten über Religion und Bildung heute.
Barokk udvariság, jezsuita hagyomány
Authors: Pálfy Eszter
Published: September 2022

Gyöngyösi István 1664-ben keletkezett munkáját, a Márssal társolkodó Murányi Vénust az utóbbi évtized kutatástörténete a barokk udvariság morálfilozófiai hagyományába illeszti. A dolgozat ezen az eszmetörténeti kontextuson belül tárgyalja a Murányi Vénust, kiegészítve a vizsgálódást a Gyöngyösi-kutatás friss, 2017-es fejleményével. Tusor Péter tanulmánya szerint a költő Gyöngyösi István korábban ismert életrajzi adatainak jelentős része téves, mert egy másik Gyöngyösi Istvánra vonatkozik. Az új történeti kutatások rávilágítottak, hogy Gyöngyösi  nem protestáns, hanem katolikus neveltetésben részesült, s a nagyszombati jezsuita egyetemre járt; ily módon a Murányi Vénus barokk jezsuita hagyomány felől való vizsgálata életrajzilag is megalapozottá válik. Ha a Murányi Vénust egybevetjük a jezsuita főúr, Csáky István Politica philosophiai Okoskodása című udvari  maximagyűjteményével, megállapíthatjuk, hogy a Gyöngyösi-mű egyes jellemzői nagy valószínűséggel a jezsuita oktatásban gyökereznek.
Egy tanulmányút költői átváltozása
Authors: Takáts József
Published: September 2022

Eötvös József Búcsú című költeményét mindeddig általában életrajzi keretben értelmezték: a szerző 1836 nyarán nyugat-európai  tanulmányútra indult, ezért vett búcsút a hazájától. E kis tanulmány felveti, hogy a költeményben fellelhető ellentmondások és hiányok talán a cenzúra kijátszásának szándékával magyarázhatók. Összefüggésbe hozza a Búcsú nyelvezetét az ellenzéki sérelmi politika szókincsével, és lehetségesnek tartja, hogy éppúgy a magyar politika 1835-1836-os válságára adott válasz, mint Vörösmarty Mihály Szózata. A republikánus hagyomány felől nézve a költeményt beszélőjének búcsúvételét az önkéntes száműzetés sejtetésének tekinti, az Ubi libertas, ibi patria (Ahol a szabadság, ott a haza) latin szállóigére írott variációnak.

A dolgozatomban Bethlen Kata fogarasi adományainak kontextusát igyekszik feltárni, megmutatva ezzel a textíliák jelentőségét az adott közegben. A református egyháztámogatásban nem tekinthető jellemző gyakorlatnak a jegykendők, menyasszonyi ruhák felajánlása, rendhagyó módon azonban a patróna saját szoknyájából készítette az úrasztali abrosz és a szószéktakarót. E kontextusváltásból, az anyag újrahasznosításából adódóan megváltozott a textíliákhoz társítható értelmezés, a jelek olvashatósága. A szakrális tér kiemelt pontjain megjelenő fonalas munkák szín- és mintavilága és a korábbitól eltérő funkciója lehetővé teszi és ösztönzi az új jelentésteremtést, hiszen a megjelenő motívumok erős keresztény tradícióval bírnak. Fontos szerepe van az adományozásban Fogarasnak is, amely az uralkodónők, a fejedelemasszonyok és a nemes patrónák egyháztámogatásában kiemelt helyszínnek számított. Bethlen Kata textíliái a közösséghez való tartozás kifejezése mellett saját önmegjelenítéséhez is hozzájárultak, azt alakították.
K. Papp Miklós és egy értelmiségi hálózat
Authors: Szabó-Reznek Eszter
Published: September 2022

A 19. században a sajtó nyilvánosságának térnyerésével nem tűntek el azok a technikák, amelyek segítségével a tudósok és írók kapcsolattartása működött a hivatásosodás és intézményesülés előtt. A respublica litteraria dinamikája – átalakulva ugyan, de megőrizve a kölcsönös segítség, becsületesség és szívélyesség elvét – továbbra is működött a háttérben, még ha ennek nyomai a sajtóban nem is látszanak egyértelműen. A kolozsvári lapalapító-szerkesztő K. Papp Miklós hagyatékában található levelek jelentős méretű kapcsolati hálót fednek fel, és rámutatnak annak „szívességet szívességért, könyvet könyvért, barátságot barátságért” elv alapján működő mechanizmusaira is. K. Papp erre építkezve, a hálózattípusok tudatos használatán keresztül nyerte el centrumszerepét. Hálózata régiókon és társadalmi csoportokon ívelt át, a régi arisztokrácia tagjaival, a honorácior értelmiséggel és a színházhoz kötődő egyénekkel egyaránt kapcsolatban állt, gyakran szakmai tőkévé konvertálva ezeket a kötődéseket. A levelek egy újságírói karrieren túl a 19. század végi Erdély irodalmi és színházi életének alakulását is modellezik.
„Szeresd a magyart, de ne faragd le”
Authors: Milbacher Róbert
Published: September 2022

A tanulmány a Toldit a csinosodás diskurzus kontextusában értelmezi újra, nevezetesen Arany egy korai népneveléssel kapcsolatos cikkének keretei közé helyezi. A vadságból a kulturáltságba való átmenet folyamatát mint szövegszervező elvet követhetjük nyomon a szöveg elemzése során, és arra az eredményre jutunk, hogy a Toldi inkább egy a reformkor csinosodásdiskurzusának nagyelbeszéléséhez kapcsolódik, mint a népnemzeti paradigma akkor újnak számító kontextusához. A Toldi estéjében ennek a népre is kiterjesztett nevelődéseszménynek a visszavételét, és végsősoron a nacionalista paradigma immanenciájába való feloldódását diagnosztizálja ez az írás.
Az érzelmi hatás elemzése mint a kora újkori magyar költészet olvasási stratégiája
Authors: Laczházi Gyula
Published: September 2022

E dolgozat célja, hogy a kora újkori magyar költészet egy lehetséges, de eddig kevéssé kiaknázott, az irodalomtörténeti elemzésekben csak csekély mértékben megjelenő értelmezési módjára irányítsa a figyelmet: egy olyan olvasásmódra, amely a szövege ket az érzelmi hatás és az érzelmek megjelenítésének szemszögéből vizsgálja.A kora újkori költészet esetében az érzelmi hatás kérdésének vizsgálata különösen indokoltnak tűnik, hiszen az irodalomtörténeti hagyomány e korszak költészetet többnyire az 1800 körül kialakult modern konvenciókkal szembeállítva jellemzi, s így annak alkalomhoz kötöttségét, és retorikai megalkotottságát nevezi meg legfőbb ismertetőjegyeiként. A retorikai kommunikáció hatásmechanizmusa, az érzelmek szándékolt, célzott s így jól kalkulálható felkeltése mellett oly fajta érzelmi hatásmóddal is számolni kell, amelyben a befogadó nem a kalkulált hatás által kijelölt szerep puszta betöltőjeként tételeződik. Ennek igazolására a dolgozat részletesebben elemzi Zrínyi Miklós Elégia címen ismert versét, mely halottsirató, ugyanakkor lényeges pontokon eltér az epicédium poétikában rögzített szabályaitól. Az Elégia példája ebben a megközelítésben arra vethet fényt, hogy a szubjektivitás megjelenése, a konvencionális poétikai sémától való eltérés milyen hatással lehet a befogadói viszonyulásra és az érzelmi hatásra.
A képzelő-erő betegségei

Kölcsey Ferenc legalább három írásában foglalkozott a rajoskodás (Schwärmerei) problémájával. Egyfelől egy művészetelméleti megalapozottságú szövegében, a későbbi címén ismertté vált Nemzeti hagyományokban; másfelől a politikatörténet és valláselmélet kérdéseinek összefonódását vizsgáló, az utókor által Töredékek a vallásról néven hagyományozott, rendkívül sajátos műfajiságú értekezésében. Harmadrészt pedig egy esettanulmány jellegű, az egyén szintjén egyértelműen betegségként felbukkanó jelenség cselekményesített bemutatásában (A’ karpáti kincstár). A jelen tanulmány ez utóbbin keresztül elsősorban azt vizsgálja, hogy a korabeli felfogás értelmében mik azok az (társadalmi, szociokulturális stb.) okok, amelyek az elbeszélés szerint az egyént a rajoskodásnak ebbe a betegségként felfogott (testi és lelki) változatába vezethetik; egy ilyen történet felmutatása milyen haszonnal járhat az egykori olvasó lelki egészségének a megőrzésében; illetve milyen erkölcsi előnyre vagy hátrányra tehet szert egy ilyen beteg a novella által feltárt társadalom egészének a vonatkozásában?

Published: September 2022

The ball-on-three-ball test method (B3B) is used to measure the flexural strength of cement paste and mortar. This method has the advantage of utilizing small and thin samples requiring less material and improved sensitivity, allowing a large number of samples to be tested for improved variability assessment, and assessing chemical degradation rapidly because of its relatively high surface-to-volume ratio. This paper examines two specific questions that have surfaced with the recent adoption of this test method in ASTM C1904-20, Standard Test Methods for Determination of the Effects of Biogenic Acidification on Concrete Antimicrobial Additives and/or Concrete Products. The first question is whether the mixing technique used in sample preparation impacts the results. It was found that the use of vacuum mixing (ASTM C1904-20) and Hobart mixing (ASTM C227-10, Standard Test Method for Potential Alkali Reactivity of Cement-Aggregate Combinations (Mortar-Bar Method), and ASTM C305-20, Standard Practice for Mechanical Mixing of Hydraulic Cement Pastes and Mortars of Plastic Consistency), provide comparable results; however, the high-shear mixing (ASTM C1738, Standard Practice for High-Shear Mixing of Hydraulic Cement Paste) indicated that the results were not statistically similar to the other mixing techniques. The second question is related to the timing of the test after the samples are removed from an exposure solution. It was found that the sample should be removed from the exposure solutions and tested within 10 minutes to maintain low variability. These results will provide information needed to evaluate changes for ASTM C1904-20.

Utilizing waste rubber tires in concrete as a partial replacement of aggregate reduces its carbon footprint and modifies its performance. Several researchers have evaluated the properties of crumb rubber concrete (CRC). This article evaluated the potential of one of the most promising testing techniques for concrete (i.e., the stiffness damage test (SDT)) for CRC. Fine crumb rubber aggregate (FCRA) was added as a replacement for fine aggregate at a dosage of 10 % by volume. Results reveal that compressive strength decreased by 29.5 %, 28.4 %, and 28.0 %, and tensile strength decreased by 31.1 %, 31.3 %, and 28.0 % because of FCRA at 28, 56, and 90 days, respectively. A strong relation was found between the strength and time (i.e., specimen age) and was represented linearly with R2 around 0.99 for compressive and tensile strength. The modulus of elasticity of CRC showed 27.7 %, 26.0 %, and 25.5 % reductions at 28, 56, and 90 days, respectively. Poisson’s ratio for the same mixture exhibited an increase of about 34.7 %, 31.3 %, and 28.0 % at 28, 56, and 90 days, respectively. The results showed that SDT output parameters, including the hysteresis area, stiffness, plasticity deformation, and elasticity, decreased as a function of time and were sensitive enough to quantify the change of CRC mixture properties. In addition, adding FCRA caused an increase in plasticity deformation and elasticity over time.
Simulated Strains-Based Approach for Explaining Distortion and Residual Stress in Quenched Pure Iron Cylinder
Authors: Arimoto Kyozo
Published: September 2022

Distortion and residual stress in steel parts because of heat treatment affect assembled products’ performance and life. A trial-and-error method has been used traditionally to solve problems, which requires a lot of time and cost. In the 1970s, heat treatment simulation was realized based on theoretical studies for predicting temperature, volume fraction of metallic phase, stress, strains, and so on, during the processes. In the early 2000s, an approach was established to explain the origin of distortion and residual stress based on the simulated results, especially various kinds of strains, which is called the simulated strains-based approach by the author. This approach has been made possible by simulation, which has provided results such as the time history of strain distribution. The subject of the residual stress generation mechanism in a quenched pure iron cylinder is taken here to illustrate the advantages of this approach. The classic study of this problem is Rose's illustration using a conceptual diagram of the variation of temperature and stress at the surface and center of the cylinder. In connection with this diagram, thermal shrinkage and elastic deformation, and the relationship between them and stress, are qualitatively explained. However, it is difficult to understand this diagram logically because the meaning of the correction applied to the stresses after the onset of plasticity was not clearly explained. On the other hand, the simulated strains-based approach using changes in distributions of thermal, elastic, plastic, and total strains provided a clear explanation of how the final distribution of the elastic strain, which is corresponded to the residual stress, is generated. Because quenching of steel parts produces additional transformation strain and transformation plastic strain, the quenching of pure iron is an excellent introduction to the application of a simulated strains-based approach.

Published: September 2022

Underground natural gas (NG) pipeline leakage can result in methane (CH4) buildup and migration through the soil. What is not well understood in such scenarios is how the soil conditions affect the gas migration behavior, particularly in regard to the relative contributions of specific soil properties such as soil moisture content. The objective of this study was to investigate the effects of soil properties on CH4 concentration and migration from leaking underground NG pipelines. Site characteristics such as surface cover and spatial dimensions, soil samples, and gas concentration data were collected from over 70 gas leakage sites across the United States using a standardized sampling method. Soil samples were collected from excavation sites that were 1.5′–5′ in depth. The collected soil samples were analyzed in the laboratory to measure the soil texture, permeability, and moisture. Statistical analysis was performed to evaluate the effects of soil properties on CH4 migration distance and concentration. Soil texture was consistent across geographic locations due to standardized pipeline backfill protocols, allowing for the analysis of gas concentration and transport data with respect to soil conditions. Soil moisture content was the dominant influence on the gas concentration and spreading distance. High soil moisture content was associated with reduced lateral diffusion and elevated concentrations near the leak point, whereas dry conditions were associated with reduced concentrations and greater spreading distance. Increasing soil moisture content reduced the lateral diffusion of CH4 into the soil due to water-induced tortuosity, resulting in elevated concentrations close to the leak point. Lateral migration of CH4 was suspected to be by diffusion, starting at 5 m from the leaks, while transport within the immediate vicinity of the leak was controlled by advection. These findings demonstrate a pronounced effect of soil moisture content and permeability on CH4 migration distance and concentration, providing key insight into the effects of soil conditions on NG migration and how to account for such effects in leak detection surveys.

Congenital isolated adrenocorticotrophic hormone (ACTH) deficiency due to T-box transcription factor-19 (TBX19 mutation) (MIM 201400; ORPHA 199296) usually presents in the neonatal period with severe hypoglycemia, seizures, and sometimes prolonged cholestatic jaundice. We report a case with an unusual presentation that delayed the diagnosis. A 9-month-old female patient with no relevant personal history was admitted to the emergency department due to a hypoglycemic seizure in the context of acute gastroenteritis. There was rapid recovery after glucose administration. At age 4, she presented with tonic-clonic seizures, fever, and gastrointestinal symptoms and came to need support in an intensive care unit. Low serum cortisol was documented and hydrocortisone was initiated. After normalization of inflammatory parameters, the patient was discharged with hydrocortisone. The genetic investigation was requested and compound heterozygous mutations in TBX19 were detected. This is a rare case of presentation of TBX19 mutation outside the neonatal period and in the setting of acute disease, which presented a diagnostic challenge.

Learning points

Congenital isolated adrenocorticotrophic hormone deficiency due to TBX19 mutation usually presents with neonatal hypoglycemia and prolonged cholestatic jaundice.

An uneventful neonatal period, however, does not exclude the diagnosis as the disease may be asymptomatic at this stage.

In the context of idiopathic hypoglycemia, even in the context of acute disease, hypocortisolism must always be excluded.

Genetic evaluation should be performed in cases of congenital central hypocortisolism to allow proper counselling.

The endocrine secretions of carcinomas can be life-threatening. Medullary thyroid carcinoma (MTC) is a rare cancer that is often associated with cortisol secretion, leading to paraneoplastic Cushing’s syndrome. Mutations of the proto-oncogene RET are driver molecular events in 70% of MTC cases. Here, we report a case of a woman, born in 1956, who was diagnosed with sporadic MTC in 2005, with subsequent relapses treated with focal treatments. In April 2019, she presented with severe and rapidly progressive paraneoplastic Cushing’s syndrome associated with lymph node, lung, liver and bone metastases. A supraclavicular lymph node biopsy revealed a somatic p.M918T (c.2753T>C) mutation in exon 16 of the RET proto-oncogene. The patient began treatment with selpercatinib in September 2019. Clinical efficacy was immediate. Chronic diarrhea disappeared within a few days. Clinical hypercorticism quickly disappeared, with quick improvements in muscle and skin conditions and fatigue. Two months after treatment initiation, urinary free cortisol normalized to 42 µg/24 h. Levels of the tumor markers carcinoembryonic antigen (CEA) and calcitonin also greatly decreased from baseline. After 34 months of treatment, selpercatinib elicits sustained clinical, biological and morphological responses. In summary, this case report illustrates the rapid and long-lasting antisecretory effect of selpercatinib associated with tumor control. As Cushing’s syndrome associated with medullary thyroid cancer is associated with poor prognosis, this case report is very encouraging. In addition, this suggests the potential benefit of molecular testing in all cases of medullary thyroid cancer.

Published: September 2022

Pediatric palliative care, including end-of-life care, remains a relatively new area of interdisciplinary clinical practice and research. Improving the multifaceted and complex care of children and their families involves research that (1) documents the experiences of children with serious illness, their families, and clinicians; (2) evaluates relationships between contextual factors and health outcomes; and (3) establishes a stronger foundation for child- and family-focused interventions to improve care.

Partnership among stakeholders in family-focused research begins from design through conduct of the study. This partnership is the foundation of a dynamic research process that illuminates critical perspectives. We present a hypothetical pediatric palliative study; a qualitative descriptive study of the perspectives of adolescents and young adults with life-limiting illnesses and their parents after a discussion about an end-of-life decision. Pediatric palliative care researchers, institutional review board leaders, and the parent of a child who died comment on how to balance the obligations to improve clinical care and to protect participants in research. Their recommendations include recruiting a wide range of participants, differentiating emotional responses from harm, approaching potential participants as individuals, and seeking feedback from family advisory boards and designated reviewers with content expertise.
Movimiento estudiantil de 1971 y surgimiento del maoísmo en Colombia: una lectura en perspectiva global
Authors: Urrego Miguel Ángel
Published: September 2022

El mundo vivió a finales de los años sesenta una gran movilización de universitarios, y Colombia no fue la excepción. En 1971 se presentó la más importante protesta de estudiantes de la historia del país, tanto por sus propuestas como por su duración. Su principal logro fue plantear que era posible el cambio de la universidad y de la cultura sin que fuese necesario hacer primero una revolución. La segunda experiencia de la década a nivel mundial fueron las protestas estudiantiles que sirvieron de base para la creación de partidos maoístas. Colombia tampoco fue la excepción: uno de los principales actores de ese momento fue la Juventud Patriótica (JUPA). El artículo se propone explicar, en primer lugar, la relación entre maoísmo y protestas estudiantiles tomando como ejemplo lo sucedido en países como Estados Unidos, Francia, México y Perú; y en segundo lugar, estudiar los primeros años de vida de la JUPA y su papel en la movilización de 1971. Como conclusión se argumenta que el desarrollo del maoísmo en Colombia está ligado a los debates, las realizaciones y las limitaciones de la protesta estudiantil.
