Published: June 2023

Ежегодно в нашей стране вырубается около 120 тыс. га леса, поэтому необходимо проведение искусственного лесовосстановления. Уровень механизации посева и посадки леса низкий - 22%, и для его повышения необходима разработка новых и усовершенствование существующих лесопосадочных машин. Разработка конструкций и математического аппарата должна выполняться с помощью отечественного программного обеспечения. Для определения параметров лесопосадочного аппарата необходимо определить движения его звеньев. В настоящей работе было использовано отечественное программное обеспечение. Трехмерная модель деталей и сборка лесопосадочного аппарата была смоделирована в САПР КОМПАС-3D. Имитационная модель с геометрическими параметрами, полученными из трехмерной модели, была выполнена в среде динамического моделирования SimInTech. Проведён имитационный эксперимент в SimInTech, определены траекторий движения исследуемых точек механизма захвата с учетом профиля борозды, скорости подачи и геометрических параметров конструкции. В имитационную модель также заложено требование к качеству работы машины, а именно поддержание нулевой скорости захвата относительно земли при установке саженцев в почву. Разработанная имитационная модель может быть интегрирована в управляющее устройство, для корректировки скорости вращения дисков при изменении скорости подачи машины, а также для согласования скоростей с механизмом подачи саженцев.
About 120 thousand hectares of forest are cut down in our country every year, so it is necessary to carry out artificial reforestation. The level of mechanization of sowing and planting forests is low - 22%, and in order to increase it, it is necessary to develop new and improve existing forest planting machines. The development of structures and mathematical apparatus should be carried out using domestic software. To determine the parameters of the forest planting apparatus, it is necessary to determine the movements of its links. In this work, domestic software was used. A three-dimensional model of parts and assembly of a forest planter was modeled in CAD KOMPAS-3D. A simulation model with geometric parameters obtained from a three-dimensional model was made in the SimInTech dynamic simulation environment. A simulation experiment was carried out in SimInTech, the trajectories of the studied points of the gripping mechanism were determined, taking into account the furrow profile, feed rate and geometrical parameters of the structure. The simulation model also includes a requirement for the quality of the machine, namely, maintaining a zero gripping speed relative to the ground when planting seedlings in the soil. The developed simulation model can be integrated into the control device to adjust the disk rotation speed when the machine feed speed changes, as well as to match the speeds with the seedling feed mechanism.

В статье освещено зарождение и развитие лесного дела, лесной науки и лесного образования в Императорской России, а также основные вехи развития Санкт- Петербургского государственного лесотехнического университета имени С.М. Кирова (далее Университет) в разные периоды истории. Подробно описан вклад преподавателей и студентов Университета в оборону страны в годы Первой мировой войны. На примере постреволюционной истории Университета показано, как был найден компромисс советской власти и научной элиты в 1917–1922 гг. Превращение однофакультетского института в многопрофильную Лесотехническую академию позволило усилить его ведущие позиции в эпоху «индустриализации». Особой страницей истории Университета стал блокадный подвиг коллектива. Значительное внимание в статье уделено научным достижениям ученых и сохранению преемственности научных школ. В статье также описывается современная структура Университета и планируемые направления развития.
The article highlights the origin and development of forestry, forest science and forest education in Imperial Russia, as well as the main milestones in the development of the St. Petersburg State Forest Technical University named after S.M. Kirov (hereinafter – University) in different periods of history. The contribution of teachers and students of the University to the defense of the country during the First World War is described in detail. Using the example of the post-revolutionary history of the University, it is shown how a compromise was found between the Soviet government and the scientific elite in 1917–1922. The transformation of a single-faculty institute into a multidisciplinary Forestry Academy made it possible to strengthen its leading position in the era of "industrialization". The Leningrad blockade period became a special page in the history of the University. Considerable attention in the article is paid to the scientific achievements of scientists and the preservation of the continuity of scientific schools. The article also describes the modern structure of the University and the planned directions of development.

Tujuan artikel ini adalah mendeskripsikan: 1) jaminan aksesibilitas Penyandang Disabilitas dalam peraturan perundang-undangan terkait Pemilu di Indonesia; 2) Pelaksanaan jaminan aksesibilitas Penyandang Disabilitas dalam Pemilu di Indonesia; dan 3) Faktor penghambat pelaksanaan jaminan aksesibilitas Penyandang Disabilitas dalam Pemilu di Indonesia. Metode yang digunakan adalah kajian pustaka dengan analisis model induktif. Jaminan aksesibilitas Penyandang Disabilitas dalam Pemilu di Indonesia antara lain termuat di dalam Undang-Undang Dasar 1945 Pasal 28H ayat (2) dan Pasal 28I ayat (2), Undang-Undang Nomor 8 tahun 2016 tentang Penyandang Disabilitas, Undang-Undang Nomor 10 Tahun 2008 tentang Pemilihan Umum Anggota DPR, DPD, dan DPRD, Undang-Undang Nomor 42 Tahun 2008 tentang Pemilihan Umum Presiden dan Wakil Presiden, dan peraturan pelaksana lain. Peraturan perundang-undangan tersebut mengatur agar penyandang disabilitas diikutsertakan dan difailitasi kemudahan akses baik dalam tahap pendataan, kampanye hingga tahap pelaksanaan Pemilu. Pada kenyataannya pelaksanaan Pemilu di Indonesia belum sepenuhnya terakses oleh Penyandang Disabilitas. Hal ini disebabkan oleh beberapa faktor seperti: 1) Peran keluarga yang belum maksimal; 2) sikap apatis dari Penyandang Disabilitas; 3) Ketidaktanggapan petugas penyelenggara Pemilu.; 4) wilayah Indonesia yang begitu luas sehingga sulit terakomodir dengan baik terutama daerah terpencil; 5) regulasi yang sering berubah yang sering membingungkan rakyat; 6) Penduduk Indonesia yang terlalu banyak menjadikan proses sosialisasi tidak optimal; 7) Media yang tidak terakses bagi Penyandang Disabilitas. Melihat belum tercipta sinergi yang maksimal antara harapan, aturan dan kenyataan menjadikan pemerintah Indonesia perlu segera memperbaiki sistem pelaksanaan Pemilu yang lebih mudah, murah, terjangkau dan tentu saja aksesibel bagi Penyandang Disabilitas. Dengan demikian diharapkan kedepannya akan tercipta suatu demokrasi dalam negara Indonesia yang penuh dengan persamaan dan keadilan bagi seluruh rakyaat Indonesia.

1000-P: The Economic Impact of Reducing Hospitalizations and Amputations in Patients with Diabetic Foot Ulcers
Authors: GAROUFALIS MATTHEW G. 
Published: June 2023

The purpose of this real-word evidence (RWE) cohort study was to evaluate whether utilization of Cyclical Pressurized Topical Oxygen (TWO2) therapy had any impact on the incidence of Diabetic Foot Ulcer related hospitalizations and amputations over a 12-month period in patients with hard to heal Diabetic foot Ulcers (DFU). An IRB approved retrospective review of deidentified DFU patient medical records was conducted at 2 US Veterans Affairs Medical Centers in Illinois and Virginia, which included demographic information on wound characteristics, clinical characteristics, neuropathy, cardiovascular disease (CVD), peripheral vascular disease (PVD), pain levels and kidney disease etc. Within the unmatched cohorts of the 202 DFU patients (91 TWO2, 111 NO TWO2)there was an 88% reduction in hospitalizations and a 71% reduction in amputations over a 12-month period for the patients treated with TWO2 therapy compared to those that did not receive TWO2 therapy. Propensity score matching was conducted showing similar outcomes and a regression analysis as preformed along with a budget impact model which demonstrated significant cost saving to the payor system. This large RWE study demonstrates the TWO2 therapy positively impacts patients quality of life and the costs associated with treating their DFU by forcing them into remission, resulting in significantly reduced rates of hospitalizations, amputations and cost outlay.

1002-P: Health Care Utilization among Telehealth Users and Nonusers with Diabetes during the COVID-19 Pandemic—Results from National Medicare Claims
Authors: SHAO YIXUE , WANG YU , ZHOU XILIN , ROLKA DEBORAH B. , ZHANG PING 
Published: June 2023

Little is known on differences in healthcare utilization between telehealth users (USER) and non-users (NON-USER) in persons with diabetes mellitus (DM) during the COVID-19 pandemic. We compared healthcare utilization of USER to that of NON-USER in Medicare beneficiaries with DM who enrolled in fee-for-service plans, using 100% Medicare claims database. The USER included persons who used any telehealth services during 03/2020-06/2020. We used nearest neighbor propensity score matching to construct a NON-USER group, who did not use any telehealth services during the pandemic (03/2020-06/2021), based on demographic, healthcare utilization, and comorbidity variables measured at baseline (03/2019-02/2020). We used linear regression to compare healthcare utilization during the later pandemic period (07/2020-06/2021) between USER and NON-USER groups, controlling for baseline characteristics. Utilization was measured as per person use of each type of healthcare services in 12 months. We also performed a subgroup analysis among patients who used fewer than 15 clinician office visits (low utilizers). The USER group used more services in all service types, ranging from 0.02 to 2.08 visits in 12 months (table). These differences were smaller for the low utilizers. We suggest future studies identify reasons behind these differences.

Diabetes duration is key information for epidemiologic studies but is not routinely collected in real-world data, such as claims and electronic health records (EHRs). This study aimed to build a predictive model for diabetes duration to nourish future research. Using data from the National Health and Nutrition Examination Survey (2009 to 2018), we identified individuals with self-reported diabetes and extracted information routinely collected in EHR. Predictors included demographics (e.g., age, sex), biomarkers (e.g., HbA1c, systolic blood pressure), diabetes-related comorbidities (e.g., retinopathy, end-stage renal disease), and glucose-lowering therapy (e.g., insulin, metformin). We used diabetes duration (in years) as the outcome. We compared the ordinary least square (OLS) model, least absolute shrinkage and selection operator (LASSO) regression, random forest, and extreme gradient boosting (XGBoost) models, using 10-fold cross-validation for tuning hyperparameters. A total of 3,267 survey participants were included, with a median diabetes duration of 9 years (Q1: 4 years, Q3: 16 years). The LASSO regression achieved the best performance (Root Mean Square Error [RMSE]: 7.62, Mean Absolute Error [MAE]: 5.74, Average Error [AE]: 0.53), followed by random forest (RMSE: 7.63, MAE: 5.74, AE: 0.47), XGBoost (RMSE: 7.63, MAE: 5.76, AE: 0.55), and OLS model (RMSE: 7.64, MAE: 5.76, AE: 0.59). The random forest algorithm identified age, insulin therapy, metformin monotherapy, retinopathy, and HbA1c as the predominating factors associated with diabetes duration. The prediction is more accurate if the diabetes duration is: 1) &lt;10 years (RMSE:4.43, MAE: 3.66, AE: 0.10); 2) 10 to 20 years (RMSE: 5.71, MAE: 4.72, AE: 0.79). Our model could properly predict the diabetes duration using information available in EHR data. Model performance improved when applied to individuals living with diabetes for shorter than 20 years.
