Authors: Shrestha Manisha , Rayamajhi Anusha , Basnet Rohan , Poudel Shanta , Bhattarai Urza , Risal Ujjwol , Sharma Sanjib Kumar
Published: December 2023

Gastric antral vascular ectasia (GAVE) is a rare condition which accounts for 4% of the nonvariceal acute upper gastrointestinal (GI) bleeding. The mean age of diagnosis is 70 years. This condition is often misdiagnosed as hemorrhagic antral gastritis or portal hypertensive gastropathy. In this case report, we report the oldest person to date in the South Asian population with upper GI bleeding caused by GAVE. An 87-year-old, female, known case of chronic obstructive pulmonary disorder and systemic hypertension under medication for 2 years, current smoker, previous alcohol consumer presented to the emergency department with complaints of hematemesis, melena, and easy fatigability. On general physical examination, pallor was present. A provisional diagnosis of chronic anemia secondary to upper GI bleeding was made. Upper GI endoscopy revealed ectatic vessels radiating from the gastric antrum which was diagnosed as GAVE. Blood transfusion was done, and three sessions of argon plasma coagulation were done. In the oldest old, GAVE is an overlooked cause of GI bleeding and persistent severe anemia. It might also mimic the signs and symptoms of GI malignancy. However, the frail older adult and their caretakers must be counseled about its reversibility, good prognosis, and nonmalignant nature. Simple intervention can improve the quality of life in the frail oldest old.
Ultrasound-guided quadratus lumborum block: Posterior versus anterior approach in paediatrics undergoing laparoscopic inguinal hernia repair
Authors: El Malla Dina A. , El Mourad Mona B.
Published: December 2023

Background and Aims:

Regional anaesthesia has gained popularity in managing post-operative pain in paediatric patients. Quadratus lumborum block (QLB) is recognised as one of the peri-operative pain management techniques used during abdominal surgeries. However, no consensus about the best approach has been reached.

Material and Methods:

Sixty paediatric patients with ages ranging from 1 to 6 as well as classification I and II of the American Society of Anesthesiologists, scheduled for laparoscopic inguinal hernia, were allocated to receive either a posterior approach (Group I) or an anterior approach (Group II) QLB. Twenty four-hour morphine consumption, the face, legs, activity, cry, and consolability (FLACC) score, duration of analgesia, performance time, and block-related complications were recorded.

Results:

Group II showed significantly lower morphine consumption as well as a longer duration of analgesia (P= 0.039*, 0.020*, respectively), with an equivalent period for block performance being reported in the two groups (P= 0.080). At 2, 4, 6, and 12 hours post-operatively, the FLACC scores were substantially diminished in Group II compared to Group I (P= 0.001*, 0.012*, 0.002*, 0.028*, respectively). However, at twenty-four hours, comparable pain scores were observed between both groups (P= 0.626). In addition, there were no block-related complications.

Conclusions:

In paediatric patients scheduled for laparoscopic inguinal hernia repair, the ultra-sound-guided anterior approach of the QLB was associated with significantly reduced post-operative morphine consumption, a lower FLACC score, and a longer analgesia duration when compared to the posterior approach.
Traditional Chinese medicine (Lianhua Qingwen) as an add-on to Western medicine for mild to moderate COVID-19 patients: A meta-analysis
Authors: Ng Daniel Kwok-keung , Leung Shuk-yu , Au Yi-tak , Li Han-dong , Feng Wei-bin , Yum Chi-hang , Hon Kam Lun E
Published: December 2023

Background:

Proprietary traditional Chinese medicine (TCM) such as Lianhua Qingwen (LQ) has been promoted to be an over-the-counter product for treating infectious diseases including COVID-19. This meta-analysis aimed to evaluate the efficacy of LQ in adults with mild or moderate COVID-19 diseases.

Materials and Methods:

The authors conducted the literature search using six electronic databases (Chinese and English) from the inception dates of the different database to October 31, 2022, using search for relevant keywords, that is, “severe acute respiratory syndrome coronavirus 2,” “COVID-19,” “Lianhuaqingwen,” and “Lianhua Qingwen” to identify randomized controlled trials (RCTs). Three reviewers independently identified studies, extracted the data, and assessed study quality. All analyses were conducted on RevMan 5.3.

Results:

A total of 6 RCT studies involving patients with COVID-19 were identified according to the inclusion and exclusion criteria. The quality of included studies was moderate. LQ was effective in improving overall clinical efficacy (RR = 1.25; 95% CI: 1.14–1.36; P < 0.001), and relieved three features, that is, cough (WMD = –2.04; 95% CI: –3.92 to –0.17; P = 0.03), fatigue (WMD= –2.58; 95% CI: –3.45 to –1.71; P < 0.001), and chest CT resolution (RR = 1.21; 95% CI: 1.02–1.43; P = 0.03) but not resolution of fever (WMD = –0.46; 95% CI: –1.54 to 0.62; P = 0.40) among adults with mild or moderate COVID-19. LQ was also effective in reducing the rate of conversion to severe cases (RR = 0.57; 95% CI: 0.37–0.86; P = 0.007). The adverse events rate (RR = 0.74; 95% CI: 0.40–1.37; P = 0.35) were similar between LQ group and the control group.

Conclusion:

This meta-analysis of six RCT shows that the Lianhua Qingwe (LQ) as an add-on to Western medicine achieves a higher overall clinical efficacy, faster resolution of cough, fatigue and chest CT changes than Western medicine alone in COVID patients. LQ is also effective in reducing the rate of conversion to severe cases. Further double-blinded placebo-controlled randomized studies are warranted for LQ as a stand-alone treatment for the “heat” subtype of mild to moderate COVID diseases.
Pushed, pulled and pushmi-pullyu fronts of the Burgers-FKPP equation
Authors: An Jing , Henderson Christopher , Ryzhik Lenya
Published: December 2023

We consider the long time behavior of the solutions to the Burgers-FKPP equation with advection of a strength

\beta\in\mathbb{R}

. This equation exhibits a transition from pulled to pushed front behavior at

\beta_{c}=2

. We prove convergence of the solutions to a traveling wave in a reference frame centered at a position

m_{\beta}(t)

and study the asymptotics of the front location

m_{\beta}(t)

. When

\beta < 2

, it has the same form as for the standard Fisher-KPP equation established by Bramson:

m_{\beta}(t) = 2t - (3/2)\log t + x_{\infty} + o(1)

as

t\to\infty

. This form is typical of pulled fronts. When

\beta > 2

, the front is located at the position 

m_{\beta}(t)=c_{*}(\beta)t+x_{\infty}+o(1)

with 

c_{*}(\beta)=\beta/2+2/\beta

, which is the typical form of pushed fronts. However, at the critical value 

\beta_{c} = 2

, the expansion changes to

m_{\beta}(t) = 2t - (1/2)\log t + x_{\infty} + o(1)

, reflecting the “pushmi-pullyu” nature of the front. The arguments for

\beta<2

rely on a new weighted Hopf–Cole transform that allows one to control the advection term, when combined with additional steepness comparison arguments. The case 

\beta>2

relies on standard pushed front techniques. The proof in the case

\beta=\beta_{c}

is much more intricate and involves arguments not usually encountered in the study of the Bramson correction. It relies on a somewhat hidden viscous conservation law structure of the Burgers-FKPP equation at

\beta_{c}=2

and utilizes a dissipation inequality, which comes from a relative entropy type computation, together with a weighted Nash inequality involving dynamically changing weights.

The tribal population in and around the Western Ghats region of India is affected by both cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) with typical clinical symptoms. In this study, we recorded and analyzed seven CL and three VL cases from this emerging belt. All the cases were found as autochthonous transmission. Multiple genetic markers (minicircle kinetoplast DNA polymerase chain reaction and restriction fragment length polymorphism of 3′untranslated region heat shock protein (HSP) 70, a larger segment of HSP 70, and 6-phosphogluconate dehydrogenase [PGDH] gene sequences) were used to identify and characterize the parasite. It was found that both clinical manifestations are caused by zymodeme MON-37 of Leishmania donovani. We have investigated the detailed entomological and epidemiological aspects of disease transmission. An abundant population of the proven vector Phlebotomus argentipes was observed in the study villages.

In situ and systemic evaluations of the immune responses of HIV-infected patients to mucosal leishmaniasis have been poorly described. We describe a recently diagnosed HIV-infected patient with mucosal leishmaniasis who was characterized by a CD4 count of 85 cells/mm3 and nasal septum destruction resulting from pruritic and ulcerated nasal mucosa with crust formation and progression over 2 years. In situ and systemic immune evaluations of T cell activation, memory, and exhaustion were conducted using cytofluorometric assays, and sequencing of the Leishmania species was performed. The immune profile of HIV-infected patient with mucosal leishmaniasis shows a mixed Th1/Th2 pattern and an activated and exhausted status.
Thermomechanical Impact of Machining-Induced Heating on Tensile
Performance of Aerospace Composite Material
Authors: Imdadul Haque Md , Abdul Kader Mohammad , Helal Miah Md , Akter Anika Insana
Published: December 2023

The aim of this research is to investigate the effect of cutting temperature on
the post-machining performance of “carbon fiber-reinforced polymer” (CFRP),
providing insights into how temperature variations during machining influence
the material’s mechanical properties and structural integrity. First, cutting
temperatures generated during machining were monitored and used to categorize
specimens. These specimens were then subjected to control heating at various
temperatures, simulating the range of cutting conditions. Subsequently, the
heated specimens were left to cool naturally in ambient air. A comprehensive
tensile experiment was conducted on these specimens to assess the impact on
mechanical behavior. The tensile properties, including elastic modulus and
maximum tensile stress, were analyzed and compared across the different
temperature. This approach allowed for a systematic evaluation of cutting
temperature’s influence on CFRP’s post-machining performance, shedding light on
the material’s response to varying thermal conditions and its potential
implications for structural integrity. The results showed that temperature had a
significant influence on both the elastic modulus and maximum tensile stress of
the CFRP. The elastic modulus and ultimate tensile stress decreased with
increasing temperature. The elastic modulus and maximum tensile stress were the
lowest when the temperature was close to the glass transition temperature (Tg).
Therefore, the tensile properties of CFRP can be seriously damaged if the
material temperature is close to Tg and maintained there for a long time. The
cutting temperature should be kept away from Tg during machining. The research
outcomes promise to improve the machining practices and overall performance of
aerospace composite materials such as CFRP, contributing to more efficient,
cost-effective aerospace systems.
The impact of the COVID-19 pandemic on industrial policy in Germany and the European Union – the case of the automotive industry
Authors: Gräf Helena , Topuria Salome
Published: December 2023

The European Union (EU) and Germany were already being confronted with rapidly changing dynamics on the economic, ecological, and technological terrains prior to the Covid-19 crisis. The pandemic, however, has fully exposed critical global value chain (GVC) dependencies, jeopardising the already troubled automotive industry. By employing a historical-institutional and a pre- and post-Covid-19 industrial policy analysis, this article finds that, despite previous attempts, it was during the height of the pandemic that the implementation of green and digital industrial policy gained significant political support in Germany and the EU. In this context, there is an increased relevance of vertical industrial policy, which is geared towards the ‘twin transition’, partly altering the primarily horizontal industrial policy framework manifested in the post-Maastricht period.
Growth regimes, dominant social blocs and growth strategies: towards varieties of export-led growth regimes and strategies in Turkey and Poland
Authors: Akcay Ümit , Jungmann Benjamin
Published: December 2023

This paper aims to contribute to the literature on growth regimes by combining an operationalization of growth regimes based on growth contributions and sectoral financial balances with an analysis of dominant social blocs (DSBs). We propose the concept of a growth strategy to bridge the political and actor-oriented sphere with the macroeconomic sphere. We employ this framework to analyze the cases of Poland and Turkey. The study identifies a transition from a domestic demand-led regime to a weakly export-led regime in Poland, while Turkey experienced a shift from a domestic demand-led regime to a debt-led private demand regime and subsequently towards a weakly export-led regime, too. Both countries’ new DSBs pursue export-led growth strategies, but Poland’s strategy focuses on non-price competitiveness while Turkey relies on price competitiveness. We lay out the differences between the strategies in terms of policies and the capital fractions supporting them.
Parental Attitudes and Coping Strategies in Parents as Indicators of the Prognosis of Aggressive and Task-Oriented Coping Strategies in Adolescents in Situations of Social Conflict
Authors: Borecka-Biernat Danuta
Published: December 2023

The aim of the study was to identify family-related factors connected with aggressive and task-oriented coping strategies in adolescent youth in situations of social conflict. The study was conducted on a sample of 893 adolescents aged 13 to 15. M. Plopa’s Parental Attitude Scale (Skala Postaw Rodzicielskich, SPR), the Questionnaire for Coping Strategies in Parents in Situations of Social Conflict (Kwestionariusz Strategii Radzenia sobie Rodziców w Sytuacji Konfliktu Społecznego, KSRwSK) by D. Borecka-Biernat, and Questionnaire for Coping Strategies in Adolescents in Situations of Social Conflict (Kwestionariusz do Badania Strategii Radzenia sobie Młodzieży w Sytuacji Konfliktu Społecznego, KSMK) by D. Borecka-Biernat were used in the study. An analysis of the results of the study has indicated family discriminants of aggressive and task-oriented coping strategies in adolescents in situations of social conflict; those discriminants include the perceived parental attitudes in father, including the inconsistent, autonomous, and demanding attitude; the perceived aggressive strategy in mother and father in situations of social conflict, as well as the task-oriented strategy in mother in situations of social conflict. Identifying the determinants of aggressive and task-oriented strategies in youth might allow the caretakers of adolescents to better understand their behaviour in situations of social conflict and look at its roots from the young people’s perspective. Understanding the determinants of these behaviours is a necessary step in designing strategies that can shape individuals capable of coping with conflicts in a mature manner.
Polish Comparative Adjectives and Adverbs
Authors: Wiland Bartosz
Published: December 2023

The paper investigates the morphosyntax of Polish synthetic comparative adjectives and adverbs. It is argued that we can predict the distribution of different classes of adjectival roots and suffixes if we adopt the idea that both types of morphemes lexicalize syntactic constituents, the central tenet of Nanosyntax. The paper makes a case for two central claims. One is that the syn-sem properties of adjectives can be described with a finegrained syntactic sequence proposed for Slovak in Vanden Wyngaerd et al. (2020). The other one is that the lexical properties of Polish gradable adverbs follow from the syntactic representation of the adverb as properly containing the syntactic representation of the adjective.
“From the Speaker’s Point of View” – Subjectification as Pragmatic-Semantic Language Change
Authors: Pastuch Magdalena
Published: December 2023

The article demonstrates the importance of subjectification processes in shaping the metatextual layer of language. Using three lexical units (prawda ‘true, right’, pewnie ‘sure, certainly’ and szalenie ‘extremely, madly’) as examples, the author shows how the enrichment of their semantic structure with a subjective component led to the emergence of new propositional functions and ultimately to the establishment of a new meaning. The study is conducted diachronically, drawing on the oldest attestations of the lexemes in question. Based on a contextual analysis, the moment the meanings with a subjective component appeared is identified. The results unequivocally demonstrate that subjectification has its origin in the pragmatic domain, while its consequences are visible on the semantic level. The language material comes from both lexicographic sources and corpora. The analysis shows that subjectification is correlated with formal changes including loss of inflectional endings, loss of morphological properties, recategorization, and syntactic isolation. The paper provides evidence for the need for in-depth comparative diachronic research on subjectification.

Authors: Adedokun Theophilus Adedayo , Zulu Sylvia Phiwani , Awung Felix Nkwatta , Usadolo Sam Erevbenagie
Published: December 2023

Technology has significantly influenced the educational field, including language teaching. However, some language instructors hold negative attitudes toward technology, particularly computer-assisted language teaching (CALT), which may affect the advancement of language teaching. This study examines the attitudes of language instructors toward CALT in some South African public universities and identifies sustainable lessons that could promote the use of CALT. The study employed a quantitative research approach using content analysis and surveys to comprehensively investigate language instructors’ attitudes toward CALT. Surveys provided the required information about the attitudes of language instructors toward CALT, and content analysis and descriptive statistics were used to analyze the data and identify sustainable lessons from the attitudes of the language instructors toward CALT. Descriptive statistics were used to summarize the survey results. The analysis revealed that some language instructors have negative attitudes toward CALT, suggesting that institutions require a fundamental approach to advance the use of CALT. Sustainable lessons learned from the attitudes of language instructors toward CALT are identified, and recommendations are made about how to implement effective CALT on a personal and institutional basis. This study highlights the importance of a positive attitude toward CALT and developing a fundamental approach to using CALT in language teaching. The sustainable lessons learned from this study could inform and advance language teaching practices that employ CALT, inform future research, and promote effective language teaching practices that use CALT.

Authors: Beyazıt Utku , Yıldız Akkuş Sevilay , Bütün Ayhan Aynur
Published: December 2023

The purpose of the present study was to examine parental neglect as a predictor of socio-emotional and moral development and behavioral problems in children. The participants of the study consisted of 266 parent-child dyads in Hatay, Turkey. The data collection instruments included a Socio-Demographic Information Form, which was administered to both the parents and their children. In addition, children were administered the Social-Emotional and Moral Development Scale, whereas the parents were administered the Child Behavior Checklist and Multidimensional Neglectful Behaviors Scale. According to the stepwise regression analysis, it was found that the number of children the parents had, behavioral problems in children, nationality and duration of stay of Syrian parents in Turkey, and parental neglect predicted socio-emotional and moral development in children. In terms of behavioral problems in children, parents’ age, educational status, and neglectful behaviors, in addition to children’s socio-emotional and moral development, were found to be the significant predictors. The results of the study may shed light on the associations among parental neglect and the socio-emotional and moral development and behavioral problems in children for school authorities and mental health professionals in a cosmopolitan population with high levels of immigration.
Firm Size In Moderate Factors Affecting Islamic Social Reporting
Authors: Setiyani Norma , Citradewi Adelina
Published: December 2023

This research aims to show the influence of profitability, leverage, and size of the board of commissioners on Islamic social reporting (ISR) disclosure with company size as a moderating variable in Jakarta Islamic Index (JII) companies for 2019-2021. The population of this research was 30 companies, and the selected sample was 13 companies using purposive sampling, so the total sample data is 39. The source used secondary data from company annual reports obtained through each website. Data analysis uses moderated regression analysis (MRA). This research confirms that profitability has a positive and significant effect on ISR disclosure. The leverage and size of the board of commissioners do not affect ISR disclosure. Company size can moderate the effect of profitability on ISR disclosure. Company size cannot moderate the influence of leverage and board size on ISR disclosure. This research shows that effective asset management can increase ISR disclosure for businesses that achieve high profitability, so the research results can be a reference for business management when making ISR policies, especially those related to Islamic business. This research can also be used as evaluation material for company management in determining policies related to ISR, especially in Islamic-motivated companies.

Published: December 2023

Usaha mikro kecil menengah atau UMKM merupakan pelaku usaha terbesar di Indonesia yang berperan penting dalam penyerapan tenaga kerja dan pembentukan produk domestik bruto (PDB). Namun potensi besar tersebut masih terhalang oleh permasalahan permodalan. Mayoritas UMKM masih mengandalkan permodalan dari perbankan yang cenderung sulit untuk didapatkan dan pinjaman modal dari perorangan yang tidak menjamin keberlangsungan bisnis dalam jangka panjang. Crowdfunding merupakan fintech yang bisa dijadikan sebagai alternatif dalam menghadapi masalah permodalan ini. Namun masih banyak kekurangan crowdfunding yang mengakibatkan keengganan untuk memanfaatkannya seperti rentan terhadap penipuan, waktu pengembalian dana yang lama dan dana yang kembali tidak sesuai perjanjian. Berdasarkan permasalahan tersebut, maka dibutuhkan adanya pengembangan aplikasi crowdfunding syariah yang dijalankan berdasarkan prinsip-prinsip syariah sebagai alternatif pendanaan modal untuk UMKM. Aplikasi crowdfunding syariah ini membutuhkan adanya perancangan backend agar dapat berjalan dengan baik dan optimal. Perancangan backend tersebut dibuat dengan menggunakan framework Laravel dan metode iterative incremental, serta MySQL sebagai sistem basis data. Aplikasi crowdfunding yang dirancang diuji dengan menggunakan metode blackbox testing dan user acceptance test. Berdasarkan hasil  pengujian, aplikasi crowdfunding sudah memenuhi kebutuhan pengguna dalam menjadi alternatif permodalan dengan hasil user acceptance test sebesar 93.7% untuk UMKM, 96.4% untuk investor dan 92.1% untuk admin.

Published: December 2023

Penelitian ini bertujuan untuk mengkaji dan memahami tentang kebijakan pemerintah daerah Bondowoso dalam menangani masalah pencemaran udara beracun yang disebabkan oleh aktifitas penambangan panas bumi atau geotermal di kawasan Kawah Wurung Bondowoso. Penelitian ini menggunakan metode yuridis normatif.  Penelitian ini menggunakan teknik pengambilan bahan hukum berupa pengumpulan data normatif yang bersumber dari bahan hukum primer berupa undang-undang, peraturan pemerintah dan bahan sekunder berupa publikasi yang berkaitan dengan hukum namun bukan dokumen resmi. Hasil penelitian menunjukkan bahwa pemerintah Kabupaten Bondowoso cenderung belum memiliki cara yang tepat dalam membuat kebijakan terhadap pengendalian lingkungan hidup terhadap adanya pencemaran udara kawasan geotermal Kawah Wurung Bondowoso dan tidak ditemukan satu hukum berupa Peraturan Pemerintah Daerah Kabupaten Bondowoso untuk mengatur hal tersebut, dikarenakan fakta lapangan bahwa  kondisi fisik wilayah Kecamatan Sempol memiliki topografi yang dominan curam, berpotensi terjadinya tanah longsor dan juga banjir.  Kebijakan yang dilakukan oleh pemerintah Kabupaten Bondowoso terkait permasalahan yang terjadi di tambang geothermal Kawah Wurung masih jauh dari prinsip-prinsip dan Asas-Asas Umum Pemerintah yang Baik dan cenderung hanya sebagai kebijakan politis.

Plastik malzeme, otomotivden beyaz eşyaya, kırtasiye malzemelerinden oyuncaklara, mutfak eşyalarından ofis malzemelerine kadar her sektörde yerini almıştır. Plastik enjeksiyon yöntemi, plastik parça üretiminde en çok kullanılan imalat yöntemidir. Üretimi talep edilen plastik malzemeler için, plastik enjeksiyon kalıpları tasarlanmaktadır. Bu kalıplar tasarlanırken, ilk aşamada ürün tasarımı göz önüne alınır. Üretime uygun, kısa sürede ve kaliteli bir imalat yapmak için en önemli faktör tasarlanan ürünün, üretilebilir olmasıdır.

Bu çalışmada plastik bir kırtasiye-oyuncak sektörü diyebileceğimiz bir sulu boya paletinin ürün tasarımı ve kalıp tasarımı aşama aşama incelenecektir. Ürün, kalıplamaya uygun hale getirilip, kalıp tasarımı gerçekleştirilmiştir. Tasarımı biten ürün, daha üretimi yapılmadan yolluk ve soğutma sistemlerinde karşımıza çıkabilecek olası hataları gözlemlenmiştir. Yapılan analize göre yolluk giriş yerinin en iyi ürün merkezinden olacağı ama maliyeti arttırdığı tespit edilip soğuk yolluk sistemi kullanılarak bir tasarım gerçekleştirilmiştir. Hava birikecek yerler tespit edilmiştir, bu bölgelere hava çıkışını sağlayacak cepler kullanılması önerilmiştir. Soğutma kalitesiyle ilgili yapılan analiz ile ürünün et kalınlığının homojen olduğu ve erken donma ihtimalinin düşük olduğu tespit edilmiştir. Bu yüzden et kalınlığına müdahale edilmesine gerek görülmemiştir.

Pada era perkembangan teknologi saat ini, identifikasi seseorang manusia dapat dilakukan dengan menggunakan sistem pengenalan biometrik, sistem bisa digunakan untuk membedakan antara orang yang satu dengan yang orang lain. Proses yang dilakukan dalam mengenali wajah seseorang dalam suatu gambar citra secara otomatis dilakukan dengan menggunakan bantuan perangkat dan software tertentu. Salah satunya dapat dilakukan dengan menggunakan perangkat komputer dengan menggunakan metode tertentu pada proses pengolahan citra. Terdapat beberapa metode yang bisa digunakan dalam melakukan pengenalan ciri wajah yang salah satunya adalah Principal Component Analysis. Metode ini bekerja dengan cara mencocokan matrik vektor wajah manusia dengan data citra yang telah direkam dalam database. Namun, untuk mengetahui apakah  suatu citra terdapat wajah manusia atau tidak, digunakan metode Viola Jones untuk melakukan proses deteksi wajah. Tahapan-tahapan tersebut perlu untuk dilakukan dalam melakukan pengenalan wajah siswa. Studi kasus dilakukan dengan menggunakan sampel wajah siswa pada SMK Raden Paku Wringinanom untuk mengetahui tingkat akurasi sistem pengenalan wajah menggunakan algoritma Viola-Jones dan PCA. Sistem pengenalan wajah ini disusun dan dirancang menggunakan aplikasi MATLAB R2016A. Untuk mengetahui tingkat akurasi dari sistem, penulis melakukan beberapa proses dalam meneliti dan mengembangkan aplikasi pengenalan wajah ini secara realtime. Proses yang dilakukan adalah proses pelatihan dan pengujian. Pada studi kasus ini, diketahui bahwa tingkat akurasi sistem pengenalan wajah manusia dengan menggunakan metode Viola-Jones dan Principal Component Analysis didapatkan hasil yang cukup akurat, yakni mencapai 92,5%.

Abstract. Tropical cirrus clouds, i.e., any type of ice cloud with tops above 400 hPa, play a critical role in the climate system and are a major source of uncertainty in our understanding of global warming. Tropical cirrus clouds involve processes spanning a wide range of spatial and temporal scales, from ice microphysics on cloud scales to mesoscale convective organization and planetary wave dynamics. This complexity makes tropical cirrus clouds notoriously difficult to model and has left many important questions stubbornly unanswered. At the same time, their multi-scale nature makes them well-positioned to benefit from the rise of global, high-resolution simulations of Earth's atmosphere and a growing abundance of remotely sensed and in situ observations. Rapid progress on our understanding of tropical cirrus requires coordinated efforts to take advantage of these modern computational and observational abilities. In this opinion paper, we review recent progress in cirrus studies, highlight important unanswered questions, and discuss promising paths forward. Significant progress has been made in understanding the life cycle of convectively generated “anvil” cirrus and the response of their macrophysical properties to large-scale controls. On the other hand, much work remains to be done to fully understand how small-scale anvil processes and the climatological anvil radiative effect will respond to global warming. Thin, in situ formed cirrus clouds are now known to be closely tied to the thermal structure and humidity of the tropical tropopause layer, but microphysical uncertainties prevent a full understanding of this link, as well as the precise amount of water vapor entering the stratosphere. Model representation of ice-nucleating particles, water vapor supersaturation, and ice depositional growth continue to pose great challenges to cirrus modeling. We believe that major advances in the understanding of tropical cirrus can be made through a combination of cross-tool synthesis and cross-scale studies conducted by cross-disciplinary research teams.

Abstract. Paul Jozef Crutzen was a pioneer in the atmospheric sciences, a kind-hearted and humorous person with empathy for the private lives of his colleagues and students, and a man who upheld the highest scientific standards for himself and for others. He made fundamental scientific contributions to a wide range of scientific topics in all parts of the atmosphere, from the mesosphere to the stratosphere and from the stratosphere to the troposphere. In particular, he was the first to describe the NOx-driven ozone depletion cycle in the stratosphere, he was among the first to develop the idea of chemical formation of ozone in the troposphere, he provided key concepts to explain the “ozone hole”, and he made fundamental discoveries about the effects of biomass burning on the troposphere. Understanding and addressing the causes of anthropogenic air pollution and climate change were the driving motivations for his scientific work. In his work, he did not shy away from challenge and provocation. His work on smoke from fires after a potential nuclear war inspired new research on a concept now known as “nuclear winter”. He also initiated the reopening of the debate on “geoengineering” – a concept now referred to as “climate intervention”. He also brought the term “Anthropocene” to the popular debate. Moreover, he had a strong influence on atmospheric science through his educational role; there is a very large number of outstanding scientists who started their career with scientific work with Paul. In 2000, Paul was among the founders of the journal Atmospheric Chemistry and Physics, which was unique at the time in providing public discussion of published preprints as well as what we now call “open access” to published articles. Paul's work on human impacts on atmosphere and climate has had a profound impact on the environmental policies of many countries for decades. In the future, his work will continue to be a guide for generations of scientists and environmental policymakers to come.
Levee system transformation in coevolution between human and water systems along the Kiso River, Japan

Abstract. Floodplain societies decide whether to protect themselves against floods (fight), live with floods (adapt), or a combination of the two. The formation of a levee system is an important factor in determining whether a society fight or adapt to flood; however, these factors have been considered as fixed boundaries in previous studies in human-flood interaction. We analyse a levee system transformation process covering the past century, from the indigenous ring-type levee system with floods to modern continuous levees against floods in the Kiso River basin, Japan, by applying a historical sociohydrological approach. The results show degradation processes of the indigenous levee system and traditional communities alongside the installation of modern continuous levees, and a trade-off relationship was observed between the lengths of both. There are interactions between the levee systems and the human-water system through various water uses and different scale components, and the dynamics within the region are connected to external socioeconomic trends through the installed modern levees and institutions.
