Published: January 2022

Pesisir Kabupaten Kendal sebagai pesisir Muara Kali Bodri, dengan adanya angkutan sedimen yang terendap di muara sungai berpotensi terjadi proses sedimentasi. Morfologi pantai yang menjorok ke arah laut berpotensi terjadi abrasi, sehingga berdampak terhadap pola perubahan garis pantai. Tujuan penelitian adalah untuk mengetahui wilayah rentan abrasi/akresi pantai di Muara Sungai Kali Bodri periode tahun 2014 – 2019. Metode penelitian ini merupakan penelitian studi kasus dengan analisis secara kuantitatif dengan pendekatan multi temporal citra satelit menggunakan perangkat lunak Digital Shoreline Analysis System (DSAS). Data penelitian meliputi pasang surut, batimetri, gelombang, angin, nilai D50 sedimen dasar, garis pantai tahun 2014-2016 dengan citra Landsat 8 dan tahun 2016-2019 dengan Citra Sentinel 2A. Hasil penelitian menyatakan bahwa perubahan garis pantai pada tahun      2014-2016 terjadi akresi sebesar 12,80 ha dan abrasi sebesar 2,93 ha, sedangkan perubahan garis pantai pada tahun 2016-2019 terjadi akresi seluas 9.88 ha dan abrasi seluas 3.35 ha. Total perubahan garis pantai tahun 2014–2019 mengalami akresi pantai seluas 22,68 ha dan mengalami abrasi seluas 6,28 ha, sehingga disimpulkan proses akresi pantai lebih dominan seluas 16,40 ha.    Coastal of Kendal Regency as the coast of Kali Bodri Estuary, with sediment transport in the river estuary has the potential to cause sedimentation. Beach morphology that protrudes towards the sea has the potential to cause abrasion, thus affecting the pattern of changes in the coastline. The purpose of this study was to determine the area of prone to abrasion/accretion of beaches in the Kali Bodri River in the period 2014 - 2019. This research method is a case study research with a quantitative analysis with a multi-temporal approach to satellite imagery using the Digital Shoreline Analysis System (DSAS) software. The research data includes tides, bathymetry, waves, wind, D50 values of basic sediments, coastlines in 2014-2016 with Landsat 8 imagery, and in 2016-2019 with Sentinel 2A imagery. The results of the study stated that changes in the coastline in 2014-2016 occurred accretion of 12.80 ha and abrasion of 2.93 ha, while changes in the coastline in 2016-2019 occurred accretion of 9.88 ha and abrasion of 3.35 ha. The total shoreline changes in 2014-2019 underwent beach accretion of 22.68 ha and experienced abrasion of 6.28 ha, which concluded that the beach accretion process was more dominant at 16.40 ha.

Published: January 2022

Perairan Samudera Hindia bagian Selatan Pulau Jawa merupakan perairan yang dinamis karena dipengaruhi oleh sistem monsun yang memicu sistem arus musim. Perubahan kecepatan arus dapat menyebabkan pergerakan lapisan pada permukaan laut yang membangkitkan pengadukan dan percampuran secara horizontal sehingga kecepatan dan arah arus merupakan salah satu faktor penting penyebaran suhu maupun salinitas pada kolom perairan. Keterkaitan yang kompleks antar parameter oseanografi di perairan Samudera Hindia bagian selatan Pulau Jawa terutama kondisi arus, angin, suhu, dan salinitas sangat menarik untuk diteliti dan dipelajari. Tujuan penelitian ini yakni mengetahui pengaruh arus terhadap sebaran horizontal suhu dan salinitas pada mixed layer, thermocline/halocline, dan deep layer. Pada penelitian ini menggunakan data arus, suhu, dan salinitas bulanan (Januari 2014-Desember 2018) reanalysis dari Marine Copernicus. Data tersebut diolah menggunakan Interactive Data Language (IDL) dengan metode komposit dan korelasi pergrid. Berdasarkan hasil penelitian didapatkan bahwa arus permukaan Musim Peralihan 2 bergerak paling kencang mencapai 0,266 m/s, dengan suhu permukaan terpanas yakni 30oC pada Musim Peralihan 1 dan kadar salinitas tertinggi berada pada lapisan dalam mencapai 34,8-34,875 psu terutama saat Musim Peralihan 1. Pengaruh arus terhadap sebaran horizontal suhu dan salinitas pada mixed layer, thermocline/halocline, dan deep layer cukup lemah yang dibuktikan dengan semakin kencang arus maka nilai suhu belum tentu rendah dan nilai salinitas tinggi.

Über den Anfang von Walter Benjamins Aufsatz „Zur Kritik der Gewalt“ anlässlich des hundertjährigen Jubiläums seiner Veröffentlichung
Authors: Fenves Peter
Published: January 2022

As a commentary on the initial paragraph of Benjamin’s “Zur Kritik der Gewalt,” this article shows that its characterisation of the “sphere of moral relations” as circumscribed by the poles of law and justice generates the rationale for the critique of violence. After describing how Benjamin reproduces the structure of Kant’sMetaphysik der Sitten, the article outlines the procedure whereby the initial definition ofGewaltas an “intervention” into moral relations is supplemented by an exposition of the situation in which law “encroaches” upon “the living” by presenting itself as an “expiation” (Sühne) of moral ambiguity; but inasmuch as the sphere of moral relations is constitutively split between the mutually repugnant poles of law and justice, the process of expiation intensifies the ambiguity of the situation law purports to resolve. Benjamin’s solution to this dilemma consists in claiming the reality of “de-expiation” (Entsühnung), which he associates with “pure” and thus “divine” violence.
Verstörung und Vertrauen
Authors: Gutschmidt Rico
Published: January 2022

Proceeding from a philosophical interpretation of negative theology as performatively undermining our seeming understanding of the absolute and thereby evoking a transformative experience, this paper emphasises the philosophical significance of negative theology by linking it to Karl Jaspers’ notion of the universal limit situation of existence. Against this background, an analysis of mystical and psychotic experiences shows how certain similarities between the two can be understood as constituting a particular mental state in which the universal limit situation is experienced personally. Moreover, experiencing the limit situation, be it through this mental state or through certain moods or feelings, can be transformative and may lead to an attitude of groundless trust that acknowledges the incomprehensibility of the human condition. The paper argues that this reading of negative theology provides a better understanding of the parallels between mysticism and psychosis and may be fruitfully applied in therapy.
Die Verursachung der Vergangenheit
Authors: Hoffmann Christian Hugo
Published: January 2022

How can a present or future event causally influence one in the past? Even though the case of such a relationship is often quickly dismissed as impossible, this paper suggests that this reaction is hasty and omits interesting as well as substantive arguments and considerations. In an introductory synopsis of the metaphysics of causality, we first present and discuss arguments for and against the possibility of backwards causation. On the other hand, we suggest that a probabilistic notion of causality according to Suppes need not exclude that causes occur temporally after their effects.
Adrift between republican values and plurilingual policies: (pre)primary school teachers’ reported practiced language policies in Strasbourg
Authors: Flom Haley , Young Andrea S.
Published: January 2022

In France, education policies concerning children’s home languages have recently changed, with the country’s highly centralized and monolingual national education system now promoting inclusive language policies, specifically at the pre-primary level (M.E.N. (Ministère de l’Education Nationale). 2016. Statégie langues vivantes. 22 janvier 2016. Paris). However, such prescribed practices run contrary to historically rooted monolingual ideologies and interpretations of the values of the République (Hélot, Christine. 2008. « Mais d’où est-ce qu’il sort ce bilinguisme? » La notion de bilinguisme dans l’espace scolaire français. In Gabriele Budach, Jürgen Erfurt & Melanie Kunkel (eds.), Écoles Plurilingues – Multilingual schools: Konzepte, Institutionen und Akteure. Internationale Perspecktiven, 55–80. Frankfurt: Peter Lang). Understanding the policies and ideologies influencing teachers’ agency to implement inclusive language policies via their own classroom practices is vital to developing effective teacher education programs. In this paper, we analyze data from our research into pre-primary and primary school teachers’ attitudes, beliefs, and knowledge about their pupils’ plurilingualism and its place in the classroom, with the aim of answering the following research questions: what are some of the reported practiced language policies in these classrooms, and on which underlying ideological foundations have they been constructed? In order to uncover the ideological challenges to implementing plurilingual education approaches and language-supportive pedagogies, semi-directed interviews with eight pre-primary and primary school teachers working in low-resource contexts (primarily low-income families) were conducted, transcribed and analyzed using the constant comparative method.

In this paper, a simple method for hydrophobic modification of polyvinyl alcohol (PVA) was found. Using N-methylpyrrolidone as solvent, PVA was esterified with stearyl chloride without catalyst. The modified hydrophobic polyvinyl alcohol (MPVA) was well verified by FT-IR and XRD. Using air filter paper as receiving substrate and MPVA as spinning solution, MPVA air filter paper with water resistance and high filtration performance was prepared, and hydrophilic PVA air filter paper was prepared as controlled sample. SEM was used to observe the fiber morphology on the surface of the two composite filter papers. The contact angle of hydrophobic MPVA air filter paper (25:3) was 121.9°, and the filtration efficiency was increased to 99.9955 % and the filter initial resistance increased to 90 Pa.
Torsional Overload Fracture of Twist-off Bolts During Assembly
Authors: Neidel A. , Gädicke T. , Ullrich T.
Published: January 2022

Supposedly simple cases of failure are most often best suited to communicate the principles of component failure analysis in the field of materials engineering to a wide readership, especially to those peers in the specialist community who are just beginning to familiarize themselves with the subject. The present case of failure relates to components that failed as early as during the assembly, and more specifically, during the final assembly stage of combustion chamber components for heavy-duty gas turbine engines. Hence, they lost their functionality (in fact, the common definition of component failure). At tightening torques of the nuts opposite of the tapered heads as low as below 25 Nm, so-called twistoff bolts which, when welded into combustion chamber sheets, take on the function of stud bolts, sheared off. By way of exception, a materialographic failure analysis could show that the primary cause of the failure was not the component’s design, but the disregard of the drawing specifications during final assembly. However, on a secondary level, design deficiencies had to be mentioned, as untempered welded joints in martensitic chromium steels invariably act as metallurgical notches. If the respective part is subjected to dynamic loads, as is the case in virtually all turbo machinery, they are thus to be avoided.
Changing discourses of climate change: building social-ecological resilience cross-culturally
Authors: Plastina Anna Franca
Published: January 2022

Social-ecological resilience (SER) is setting a new trend of thinking about environmental issues since it considers climate unpredictability as the norm in the Anthropocene and climate disturbance as offering opportunities for change. This paper argues that SER can be conceptualized as a function of narrative text and talk in the recent practice of online environmental activism. Based on a case study, the investigation explores a TED talk by the US environmentalist, Al Gore, and a web-based text by the Indian activist, Vandana Shiva, seeking how meanings of climate change enhance resilience building. A mixed-method research design is used to perform a discursive frame analysis on the sample discourses, guided by key resilience-building principles, and framed by the methods of critical discourse and frame analyses. The twofold aim is to analyse how micro-linguistic features mediate social-ecological memory and novelty as key SER drivers, and how macro-discursive frames are selected to shape meanings cross-culturally. Based on these findings, the comparative analysis at the socio-discursive level highlights how SER ideologies underpinning these discourses particularly diverge in the context of the Global North/Global South divide. Overall, the study findings shed light on the multiple meanings of SER shaping more constructive responses to climate change.
Structuring Workers' Bargaining Power in Mexico's Strawberry Fields
Authors: Fischer-Daly Matthew
Published: January 2022

Workers shut down production and transportation of strawberries during the peak of the 2015 harvest in San Quintín, Mexico, which supplies winter berries to US markets. In the years since the strike, strike-settlement wage increases have eroded, commitments to register workers in the national social security system fell far short, and no workers gained representation by a union in collective bargaining with their employer. This case analyses the limited strike outcomes and persistent gaps in labour law compliance based on interviews and observation in 2019 and 2020. Building on the power resources approach, it highlights the historical character of structural power. Falling short of achieving strike demands underscored constraints on workers’ disruptive capacity. The case suggests that reading structural power as a dynamic complex of actions by employers, national states and workers enhances the concept’s ability to predict effects of collective action on social relations of production.

Daam2 Regulates Myelin Structure and the Oligodendrocyte Actin Cytoskeleton through Rac1 and Gelsolin
Authors: Cristobal Carlo D. , Wang Chih-Yen , Zuo Zhongyuan , Smith Joshua A. , Lindeke-Myers Aaron , Bellen Hugo J. , Lee Hyun Kyoung
Published: January 2022

Myelin is essential to neuronal health and CNS function, and oligodendrocytes (OLs) undergo a complex process of cytoskeletal remodeling to form compact myelin sheaths. We previously discovered that a formin protein, Dishevelled associated activator of morphogenesis 2 (Daam2), suppresses OL differentiation through Wnt signaling; however, its role in cytoskeletal control remains unknown. To investigate this, we used OL-specific Daam2 conditional knockout (Daam2 cKO) mice of either sex and found myelin decompaction during an active period of myelination in postnatal development and motor coordination deficits in adulthood. Using primary OL cultures, we found Daam2-depleted OLs showed morphologic dysregulation during differentiation, suggesting that Daam2 regulates the OL cytoskeleton.In vivoscreening identified the actin regulators Rac1 and Gelsolin as possible effectors in Daam2-deficient OL cytoskeletal regulation. Using gain-of-function and loss-of-function (LOF) experiments in primary OLs, we found that Rac1 and Gelsolin operate downstream of Daam2 in OL differentiation, with Gelsolin and Daam2 promoting and inhibiting membrane spreading during late differentiation, respectively.In vivoexperiments using Daam2 cKO mice revealed increased protein levels of Gelsolin in the developing white matter with no change in RNA levels, suggesting that Daam2 acts in a posttranslational manner to suppress Gelsolin levels.In vitrobiochemical studies show Daam2 induces Gelsolin ubiquitination and degradation in OLs. Together, our studies show Daam2 is essential for formation of functional myelin through modulation of Gelsolin levels to regulate the OL cytoskeleton. These findings further demonstrate the critical role of cytoskeletal dynamics in myelination and reveal novel avenues for treatment of a variety of white matter diseases.

SIGNIFICANCE STATEMENTProper myelin formation is essential to CNS function, and oligodendrocytes (OLs) require extensive changes in the actin cytoskeleton to form myelin sheaths. Here, we show that the formin protein Dishevelled associated activator of morphogenesis 2 (Daam2) is necessary for myelin compaction during development and motor learning in adulthood. Further, we demonstrate that Daam2 regulates OL differentiation and morphology through actin regulators Rac1 and Gelsolin. Lastly, we find that Daam2 may control myelin compaction by modulating the ubiquitination and degradation of Gelsolin through recruitment of the E3 ubiquitin ligase Nedd4. These findings reveal novel pathways for regulating myelin structure and function during white matter development.

Phosphatase and tensin homolog (PTEN) is a major negative regulator of the phosphatidylinositol-3-kinase (PI3K)/Akt/mechanistic target of rapamycin (mTOR) pathway. Loss-of-function mutations inPTENhave been found in a subset of patients with macrocephaly and autism spectrum disorder (ASD). PTEN loss in neurons leads to somal hypertrophy, aberrant migration, dendritic overgrowth, increased spine density, and hyperactivity of neuronal circuits. These neuronal overgrowth phenotypes are present onPtenknock-out (KO) and reconstitution with autism-associated point mutations. The mechanism underlying dendritic overgrowth inPtendeficient neurons is unclear. In this study, we examined howPtenloss impacts microtubule (MT) dynamics in both sexes using retroviral infection and transfection strategies to manipulate PTEN expression and tag the plus-end MT binding protein, end-binding protein 3 (EB3). We foundPtenKO neurons sprout more new processes over time compared with wild-type (WT) neurons. We also found an increase in MT polymerization rate inPtenKO dendritic growth cones. Reducing MT polymerization rate to the WT level was sufficient to reduce dendritic overgrowth inPtenKO neuronsin vitroandin vivo. Finally, we found that rescue of dendritic overgrowth via inhibition of MT polymerization was sufficient to improve the performance ofPtenKO mice in a spatial memory task. Taken together, our data suggests that one factor underlying PTEN loss dependent dendritic overgrowth is increased MT polymerization. This opens the possibility for an intersectional approach targeting MT polymerization and mTOR with low doses of inhibitors to achieve therapeutic gains with minimal side effects in pathologies associated with loss of neuronal PTEN function.

SIGNIFICANCE STATEMENTLoss ofPtenfunction because of genetic deletion or expression of mutations associated with autism spectrum disorder (ASD), results in overgrowth of neurons including increased total dendritic length and branching. We have discovered that this overgrowth is accompanied by increased rate of microtubule (MT) polymerization. The increased polymerization rate is insensitive to acute inhibition of mechanistic target of rapamycin (mTOR)C1 or protein synthesis. Direct pharmacological inhibition of MT polymerization can slow the polymerization rate inPtenknock-out (KO) neurons to rates seen in wild-type (WT) neurons. Correction of the MT polymerization rate rescues increased total dendritic arborization and spatial memory. Our studies suggest that phosphatase and tensin homolog (PTEN) inhibits dendritic growth through parallel regulation of protein synthesis and cytoskeletal polymerization.

Batik tulis merupakan salah satu warisan kesenian tradisional budaya Indonesia, khususnya bagi Daerah Istimewa Yogyakarta yang sejak tahun 2014 ditetapkan sebagai Kota Batik Dunia oleh World Craft Council. Namun, eksistensi batik tulis pelan-pelan tergeser seiring dengan perkembangan teknologi yang menyebabkan semakin maraknya produksi batik cap dan batik cetak sehingga minat generasi muda terhadap batik tulis menurun. Untuk meningkatkan minat dan motivasi generasi penerus agar lebih mengenal batik dan proses pembuatannya, dilakukan kegiatan “Pelatihan Batik dengan Pewarnaan Alami” yang ditujukan untuk anak-anak SD bekerja sama dengan Balai Agung Cendana dengan melibatkan mahasiswa sebagai instruktur. Sebelum diterjunkan menjadi instruktur pelatihan, mahasiswa terlebih dahulu mengikuti kegiatan training of trainer (ToT) agar pelatihan dapat berjalan dengan baik. Agar memiliki pemahaman yang komprehensif tentang proses pembuatan batik, para peserta ToT juga diberikan penyuluhan tentang limbah cair industri batik. Kegiatan pengabdian ini bertujuan untuk meningkatkan pengetahuan dan pemahaman para peserta ToT mengenai limbah cair yang dihasilkan dari pewarnaan batik beserta dampak lingkungan dan metode pengolahannya. Para peserta ToT nantinya akan menjadi instruktur pada pelatihan membatik sehingga diharapkan dapat turut meneruskan dan menyebarluaskan informasi mengenai pengetahuan yang diperoleh. Kegiatan pengabdian dilaksanakan dengan metode penyuluhan dan terdiri dari tahap persiapan dan sosialisasi, pelaksanaan penyuluhan, serta evaluasi. Pelaksanaan kegiatan pengabdian dilakukan pada tanggal 22 Desember 2021 dengan lokasi di Balai Agung Cendana Yogyakarta. Kegiatan penyuluhan berhasil dilaksanakan kepada para peserta sebanyak 40 orang. Hasil evaluasi kegiatan ini menunjukkan adanya peningkatan pengetahuan dan pemahaman para peserta tentang dampak limbah cair industri batik terhadap lingkungan dan metode pengolahannya sebesar 32,80%, dari semula 59,73% menjadi 92,53%.

We previously reported that high thyroid-stimulating hormone (TSH) levels are associated with papillary thyroid microcarcinoma (PTMC) progression during active surveillance. However, validation with multicenter, long-term data, and identification of appropriate age or TSH levels are needed. This multicenter retrospective study enrolled PTMC patients under active surveillance with TSH measurements and ultrasonography. The primary outcome was PTMC progression (volume increase ≥50%, size increase ≥3 mm, or new lymph node (LN) metastasis). PTMC progression according to time-weighted average of TSH (TW-TSH) groups was compared using survival analyses in overall patients and each age subgroups (<40, 40–49, 50–59, and ≥60 years). The identification of TW-TSH cutoff point for PTMC progression and trend analysis of PTMC progression rate according to LT4 treatment were also performed. During 1061 person-years of follow-up, 93 of 234 patients (39.7%) showed PTMC progression (90, 17, and 5 patients for volume increase ≥50%, size increase ≥3 mm, and new LN metastasis, respectively). The highest TW-TSH group was the risk factor most strongly associated with PTMC progression (hazard ratio 2.13 (1.24–3.65); P = 0.006), but the impact was significant only in patients aged <40 or 40–49 years (hazard ratio 30.79 (2.90–326.49; P = 0.004), 2.55 (1.00–6.47; P = 0.049)). For patients aged <50 years, TW-TSH cutoff for PTMC progression was 1.74 mU/L, and PTMC progression rates successively increased in the order of effective, no, and ineffective LT4 treatment group (P for trend = 0.034). In young PTMC patients (<50 years), sustained low-normal TSH levels during active surveillance might be helpful to prevent progression.

Gastric cancer is the 5th most common malignancy worldwide. Signet ring cell histology represents an aggressive subtype of gastric cancer, presenting at a younger age. Both breast and leptomeningeal metastases are rare locations of tumor dissemination, requiring correct and immediate diagnosis and treatment. We present a case of a 45-year old female with signet ring cell gastric carcinoma who developed both left breast and leptomeningeal metastases, requiring multiple chemotherapy lines. As far as we know, this is the first published case in  literature following multiple lines of treatment for both breast and leptomeningeal metastases from signet ring cell gastric carcinoma.

Objective. The aim was to assess the effect of surface sealants on the color stability of different composite materials.

Methodology. 120 samples were prepared using Filtek Ultimate (3M, USA), Charisma Topaz (Kulzer, Germany), and Clearfil Majesty Es-2 Premium (Kuraray Noritake, Japan) composites. The samples were polished with polishing discs and divided by test groups (n=10 for each), regarding the sealant used; Permaseal (Ultradent Products, USA), Biscover LV (Bisco, USA), Optiglaze Clear (GC Corp., Japan) and control. The samples were discolored for 144 hours in coffee solution at constant 37°C, renewing daily. Color measurements were performed at the baseline, following the sealant application, and after discoloration procedure, using a spectrophotometer (EasyShade 5, Vita-Zahnfabrik, Germany). The collected L*C*h* coordinates were converted to corresponding L*a*b* coordinates and the color changes (∆E) were calculated.

Results. All the sealants presented perceptible (> 1.2) and unacceptable (> 2.7) color changes. Biscover LV presented the lowest ∆E among all sealants (p <0.001). The highest ∆E was observed for Permaseal (p <0.001). Color changes for Optiglaze and control groups were similar (p ≥0.05). Filtek Ultimate presented the highest color stability (p <0.001), followed by Charisma Topaz and Clearfil Majesty. The combination of Filtek Ultimate with Biscover LV was considered to have the highest color stability, whereas the combination of Clearfil Majesty with Permaseal was considered the lowest, among all.

Conclusion. Experimented sealants were considered relatively effective on color stability of resin composites depending on the type of the sealant and the composite material. However, the use of surface sealants may not be advantageous every time. Biscover LV have inhibited the level of discoloration, whereas Permaseal had an increasing effect generally.
