Data statistik menunjukan, dari 262 koperasi di Kota Cimahi, tidak seluruhnya aktif dan sehat. Jumlah koperasi yang melakukan RAT sejak tahun 2016 hanya sebanyak 76 koperasi dari 420 koperasi, atau sebesar 18,10%. Sementara tahun 2020 mengalami penurunan menjadi 33,67%, yaitu dari 105 koperasi menjadi 70 koperasi, sedangkan koperasi dalam kategori sehat turun sebesar 72,5%, dari 40 koperasi menjadi hanya 11 koperasi.
Penurunan yang disebabkan situasi Pandemi Covid 19, diperburuk pula oleh kegagalan pengurus koperasi dalam membuat laporan keuangan sebagai acuan RAT. RAT sebagai syarat agar koperasi tetap eksis dan tidak dibubarkan, maka penanganan terhadap masalah ini harus dilakukan, antara lain melalui kegiatan pelatihan dan pendampingan.
Pelatihan dan pendampingan diikuti oleh 20 peserta dari koperasi aktif yang belum melaksanakan RAT. Pelatihan dilaksanakan selama3 hari , dilanjutkan dengan pendampingan berupa konsultasi dan monitoring penyusunaan laporan keuangan selama 2 hari. Baik pelatihan maupun pendampingan dilaksanakan secara daring, dan memperlihatkan hasil yang positif.

Objetivo: Diagnosticar e analisar o risco de queda da árvore de pau-ferro a partir de uma metodologia desenvolvida pelos autores, descrita na forma de um fluxograma conceitual, e que integra resultados do diagnóstico fitossanitário, de eventuais movimentações do solo, da inclinação do tronco e, também, de métodos geofísicos para a tomada de decisão do risco e manejo.Metodologia: Aplicação de procedimentos para análise do risco de queda da árvore considerando aspectos externos e internos, utilizando equipamentos não destrutivos, em paralelo ao controle da inclinação do tronco, dos deslocamentos verticais do solo e da raiz aflorada da árvore, além da caracterização do subsolo integrando métodos geofísicos.Originalidade/Relevância: Este trabalho mostra a utilização de técnicas da engenharia civil e da geofísica para a análise do risco de queda de árvore no ambiente urbano.Resultados: O exemplar arbóreo utilizado como estudo de caso apresentava cavidade aparente e apodrecimento intenso do lenho, além de raiz dobrada e descolada do solo, o que impossibilitava sua ancoragem e sustentação. A concentração de raízes abaixo da superfície do terreno não garantia a estabilidade devido a evolução dos deslocamentos verticais de superfície e inclinação do tronco para a avenida, sendo indicada sua supressão por apresentar risco de queda.Contribuições sociais/para a gestão: As árvores oferecem inúmeros benefícios e a obtenção destes privilégios depende de uma gestão adequada que considere o seu manejo e monitoramento correto. A tomada de decisão do risco de queda deve estar pautada em diversas análises, preferencialmente baseadas em métodos não destrutivos, diminuindo as incertezas para que árvores não sejam suprimidas sem necessidade.
Teachers’ Beliefs and Purposes of L1 Use and Its Effects on Students’ Oral English Improvement in Selected Primary Schools
Authors: Tamiru Olana  
Published: November 2022

The concern of this descriptive survey research was to exploratory Teachers’ Beliefs and purposes of L1 use and Its Effects on Students’ Oral English Improvement in Selected Primary Schools. To collect the data, classroom observation and interview were used. The classroom observation data were collected through checklist and the results were counted and recorded as Afan Oromo (L1) and English utterances of teachers and then changed into frequency and percentages. Similarly, the interview was presented to eight teachers and the data were recorded, transcribed, and then thematically analyzed. The findings revealed that the participant EFL teachers have favorable beliefs about use of L1 in EFL classes. However, they used more L1utterances than English utterances. For example, they made 1152 utterances among which 564/1152=49% were L1 and 588/1152=51% were English utterances. That means participant teachers used almost the same amount of L1 and English which implies that teachers over used L1 which has a negative effect on students’ oral English improvement. Therefore, teachers are recommended to be good models for their students by practicing more TL than L1 to improve their students’ oral English.

Context.—
The accurate identification of different lung adenocarcinoma histologic subtypes is important for determining prognosis but can be challenging because of overlaps in the diagnostic features, leading to considerable interobserver variability.

Objective.—
To provide an overview of the diagnostic agreement for lung adenocarcinoma subtypes among pathologists and to create a ground truth using the clustering approach for downstream computational applications.

Design.—
Three sets of lung adenocarcinoma histologic images with different evaluation levels (small patches, areas with relatively uniform histology, and whole slide images) were reviewed by 17 international expert lung pathologists and 1 pathologist in training. Each image was classified into one or several lung adenocarcinoma subtypes.

Results.—
Among the 4702 patches of the first set, 1742 (37%) had an overall consensus among all pathologists. The overall Fleiss κ score for the agreement of all subtypes was 0.58. Using cluster analysis, pathologists were hierarchically grouped into 2 clusters, with κ scores of 0.588 and 0.563 in clusters 1 and 2, respectively. Similar results were obtained for the second and third sets, with fair-to-moderate agreements. Patches from the first 2 sets that obtained the consensus of the 18 pathologists were retrieved to form consensus patches and were regarded as the ground truth of lung adenocarcinoma subtypes.

Conclusions.—
Our observations highlight discrepancies among experts when assessing lung adenocarcinoma subtypes. However, a subsequent number of consensus patches could be retrieved from each cluster, which can be used as ground truth for the downstream computational pathology applications, with minimal influence from interobserver variability.
Liver Explants of Biliary Atresia Patients Transplanted in Adulthood Show Features of Obliterative Portal Venopathy: Case Series and Guidelines for Pathologic Reporting of Adult Explants
Authors: Patel Kalyani R. , Dhingra Sadhna , Goss John 
Published: November 2022

Context.—
Biliary atresia (BA) patients can have portal vein (PV) abnormalities.

Objective.—
To investigate the explant pathology of BA patients transplanted in adulthood with a focus on portal venous abnormalities.

Design.—
Adult BA liver explants were reviewed, along with prior biopsies, Kasai portoenterostomy (KP), and relevant medical records.

Results.—
Three explants were identified; all patients were female, with age at diagnosis, KP, and liver transplantation (LT) as follows: (1) less than 1 week, 8 days, and 25 years; (2) 15 weeks, 16 weeks, and 32 years; and (3) 7 weeks, 8 weeks, and 33 years, respectively, with normalization of conjugated bilirubin within 6 months of KP and development of portal hypertension (PHTN) within 3 years of KP for all 3. The first 2 had recurrent cholangitis. Duration of pre-LT PHTN was 22, 29, and 30 years, and that of pre-LT cholangitis was 9, 3, and 0 years, respectively. All 3 explants showed hilar and extrahepatic fibromyxoid intimal hyperplasia of the PV with parenchymal hepatoportal sclerosis. Cholestasis was limited to those with a history of cholangitis. Patient 3, without cholangitis, showed delicate septal fibrosis with peripheral accentuation without biliary cirrhosis.

Conclusions.—
In the context of a functioning KP, cholestasis and biliary cirrhosis are likely related to recurrent cholangitis, which may or may not occur after KP. In the absence of biliary cirrhosis, PHTN may be secondary to obliterative venopathy. Adult BA explants should be sampled thoroughly, with a focus on hilar/perihilar connective tissue to include PV branches. Explants may not show biliary cirrhosis and should be reported with appropriate clinicopathologic correlation.
Fellowship Board Pass Rates Rising: Analysis of Pathology Subspecialty Board Examination Performance
Authors: Jacobs Jeremy W. , Booth Garrett S. , Usmani Amena , Burner James , Adkins Brian D. 
Published: November 2022

Context.—
The American Board of Pathology (ABPath) publishes annual performance data for the anatomic pathology (AP) and clinical pathology (CP) board examinations, as well as for ABPath subspecialty examinations. Overall board pass rates for all AP and CP board examinees have increased during the past decade; however, no study has analyzed the board pass rates for pathology subspecialty examinations, and whether these follow the same trend.

Objective.—
To evaluate ABPath subspecialty examination pass rates to assess the trend in certification.

Design.—
We analyzed the total number of first-time test takers and board pass rates for 11 pathology subspecialties recognized by the ABPath from 2007 to 2021, acquired from annual reports published by the ABPath. We compared the pass rates in 5-year intervals (2007–2011, 2012–2016, 2017–2021) for each individual specialty. We also analyzed the pass rate of CP subspecialties compared with AP subspecialties.

Results.—
The overall mean pass rate for ABPath subspecialty examinations during the previous 15 years was 89% (range, 78.9%–100%), with the overall pass rate being significantly higher in 2017–2021 (P = .02). The contemporary overall rate of passing was significantly higher for AP subspecialty examinations (P &lt; .001) and was higher, though not significantly, for CP subspecialties (P = .13). There were significant differences between first-time test takers' mean pass rate (92.1%), repeat test takers' mean pass rate (54.5%), and the overall rate (P &lt; .001).

Conclusions.—
Contemporary pathology subspecialty board examination pass rates are significantly higher than historic rates, possibly reflecting continuously improving and readily available preparatory materials.
Traditional ornamental techniques in the products of the Fedoskin lacquer miniature of the Soviet period
Authors: Lavrov Dmitrii Evgen'evich 
Published: November 2022

The subject of the study is the analysis of ways to restore the ornamental techniques of the Lukutinsky lacquer miniature craft, lost by the end of the XIX century and recreated during the Soviet period. The article examines the activity of miniature artists of the Fedoskinsky Labor artel - the successor of the Lukutinsky enterprise – to revive forgotten technologies for creating ornaments on lacquer products. Special attention is paid to the assistance in this process provided to the fishery by the Soviet state. The purpose of the article is to show the significant role of state support in the development of Russian folk art of the Soviet period by the example of a successful solution to the problem of restoring the lost ornamental techniques of the Fedoskinsky craft. Using comparative-historical, historical-typological, as well as historical-genetic methods, the author characterizes various ornamental techniques of Lukutinsky products, comparing them with the features of Fedoskinsky products of the twentieth century. The scientific novelty of the research consists in the analysis of the activities of the experimental laboratory at the Fedoskin labor artel, which restored the ornamental techniques of the Lukutin miniature, as well as the contribution made to this process by Fedoskin masters M. S. Chizhov, V. V. Korsakov, S. N. Tardasov. The main conclusion of the article is the statement of the importance of studying these fishing techniques for understanding the reasons for the flourishing of ornamental motifs in Fedoskinsky products in the late Soviet period, as well as the present.
