Authors:   The Korean Society for the Study of Local Education Management, Moon Tae Youl , Cha Sung Hyun
Published: November 2023

The purpose of this study is to examine financial change of revenue and expenditure in private universities in Korea since the half-tuition policy for universities. For this, the study utilized the settlement of accounts over the last 10 years (2011-2020) on a public website of university finance provided by the Korea Advancing Schools Foundation. The main findings are as follows. First, the total amount of incomings and outgoings has slightly increased from 2011 to 2014, and then has decreased by a small margin to 2020. An average of 4.5 billion per university increased from 2011 to 2020. Looking at school size and location, large universities with more than ten thousand students in the national capital region saw the biggest increase of the total sum of incomes. In contrast, middle-size universities did the biggest decrease in the same region during the same period. Second, total revenues from tuition, the unused sum brought over from the last account has decreased. Especially, middle-size universities in metropolitan cities showed the largest decrease by 12.7%p. Income from government subsidy from Ministry of Education, however, has drastically increased at universities in metropolitan cities regardless the school size. Third, over the last 10 years, a 5%p increase occurred in faculty expenses and 9.9%p increase did in scholarship from out-of-school. Especially, the largest increase of faculty expenses occurred at small size universities in metropolitan region. In addition, out-of-school scholarship expenditure has increased by a big margin in all of universities, especially, at middle-size ones regardless of regions. In contrast, tangible fixed asset purchase has decreased by 5.6%p, as showed in all of universities. Based on these findings, this study suggested that an reasonable increase of tuition with a social consensus and law of financial grants for university should be made to secure stable finance of private universities and further improve quality of higher education services.

Published: November 2023

The purpose of this study is to analyze cases of the use of school organizational technology at Haneul High School based on four types of organizational technology proposed by Perrow: daily technology, artisan technology, engineering technology, and non-routine technology. According to the school management policy based on the principal's educational philosophy, Haneul High School used school organizational technology for each type of organizational technology proposed by Perrow to improve the quality of teaching and learning centered on the student career-selective curriculum.
The results of the case analysis on the use of Haneul High School's school organizational technology are as follows. The first is the use of routine technology. 1) The classroom tour, 2) the sound of bells during class, and 3) the operation of the Morning Spark program were organized into regular routines. The second is the use of craft technology. 1) Starting with the perception of the class, 2) the class consulting system, 3) the class survey and awards for class reflection, 4) the principal and the staff for curriculum reflection, and 5) the Teacher's Research Forum (TRF) for educational reflection were continuously operated. Third, it is the use of engineering technology. 1) (Standard) The Diploma system (graduation certificate) was operated as a certified engineering technology area, 2) the CNSA-net operation as an information engineering technology area, and 3) the curriculum-friendly school space was designed as an architectural engineering technology area. Fourth, it is a nonroutine technology. For the smooth operation of the school organization structure, the "consultation system for communication and decision-making" was operated. As such, school organizations need to reasonably utilize school organizational technology based on the types of organizational technology (routine technology, craft technology, engineering technology, and nonroutine technology) according to the characteristics of the task.

Published: November 2023

For many years, historical and artistic heritage of St. Petersburg has been the main object of researchers` scientific interest. New information about the architectural and urban development of the city has been provided by studies related to the protection of surviving historical buildings. Information about the initial stage of the urbanization of the city appeared during developments in related fields of science (history, economics, literary criticism, soil science and hydrography, etc.), but the data revealed are not systematized and are scattered among individual publications. In this article, taking into account the provisions of economic geography, the formation of St. Petersburg development is considered as part of the process of improving the available infrastructure of the territories in the Neva Delta area. It is emphasized that the dynamic evolution of residential development was due to an increase in the level of investment and the impact of an evolving land use system. Specific examples demonstrate the transition from the pioneer stage of development to the reconstruction stage development, and the role of organizational and economic levers in the formation of the main morphotypes of residential development is considered.The features of urbanization in early period of St. Petersburg existence are considered on the example of the development of the southern bank of the Neva, where the target settings were clearly manifested immediately with the beginning of the development of the territory. The implemented analysis of the building development on the coastal strip to the East of the Admiralty reveals the main features of the period from 1703 to 1715 and shows that it can be considered a pioneer period in the development of the territory.

Published: November 2023

Heat stress is a significant environmental challenge that impairs broiler production, negatively impacting growth, feed intake, nutrient absorption, and gut ecology. Various methods exist to mitigate heat stress such as genetic and nutritional approaches, air conditioning, ventilation, and antibiotic growth promoters but they are often expensive and not always adequate. Keeping this view in mind, research has been focused on medicinal herbs which are available, cheap and safer to use. Amla fruit possesses antioxidant, antimicrobial, and anti-stress properties that could mitigate heat stress’s harmful effects on broilers. Therefore, this study was conducted to evaluate the impact of amla fruit powder on growth performance, gut microbiota and blood lipid profile of broilers under ambient temperature and heat stressed condition. A total of 126 broiler chicks were divided into two major groups, one group kept under ambient temperature and another group exposed to heat stress. Each major group was split into 3 subgroups with 3 replications having 7 chicks per replication. In case of each major groups, first sub groups were kept as a control and latter two groups were supplemented with 0.5% and 1.0% amla fruit powder, respectively. Total duration of the experiment was 35 days, where treatments were given with basal diet from 12 days. All the experiment birds were maintained with the similar management except the experimental diets. The results showed that body weight and body weight gain at the end of the experiment were higher in amla treated group than in the control group at both temperatures. Supplementation of amla fruit powder also improved feed conversion ratio (FCR) and dressing percentage than the control groups. Additionally, amla powder reduced TC, TAG and LDL levels and slightly increased HDL content. Amla fruit powder decreased pathogenic bacterial population such as Escherichia coli and Salmonella spp. concentration in the gut and increased probiotic bacterial concentration such as Lactobacillus spp. under both rearing temperatures. Taken together, it can be concluded that, amla fruit powder could be used as an alternative tool to improve broiler performance and mitigate the deleterious effects of heat stress on broiler chickens.

Published: November 2023

Entrepreneurship is a person's attitude and ability to handle a business or other activity in an effort to find, create, apply technology, work methods and production with improvements in providing better services in order to obtain large profits. Entrepreneurship is a process of innovation and creativity that has a high risk in producing products that can provide benefits to society and can prosper entrepreneurs. Entrepreneurship is the right solution for economic problems such as unemployment and poverty in Indonesia, because armed with only a diploma and less entrepreneurial skills so that many people queue for jobs. While the number of entrepreneurs in Indonesia is still recorded at 0.43% of the total productive age population, this figure is very far behind neighboring countries, such as Singapore where the number of entrepreneurs has reached 7%, Malaysia 5%, and Thailand 3%. Meanwhile, according to the chairman of KPPU said that in 2017 the number of entrepreneurs in Indonesia ranged from 1.6%-1.8% of the total population in Indonesia. This number is still very far from the standards of developed countries with a minimum number of entrepreneurs of 2% of the total productive age, to overcome this the government seeks to create 20,000 new entrepreneurs and the development of 1,200 Small and medium industry centers or can be called SMIs. In this article, I provide an idea of analyzing the attitude of Indonesian entrepreneurs in doing business. The method used in this article is to study the literature and review some of the references obtained. Thus, it is hoped that this idea will have a good impact on readers and provide changes for Indonesian entrepreneurs in the future. So that entrepreneurs know how the attitude they must highlight in doing business.

In COVID-19 patients, abnormal blood clotting is common, characterized by elevated D-dimer and fibrinogen levels, reduced platelets, and prolonged clotting times. The second week of infection can trigger a cytokine storm, marked by heightened proinflammatory Interleukin-6 (IL-6) levels, associated with Acute Respiratory Distress Syndrome (ARDS) and organ failure. This study compared hematological biomarkers, D-dimer, and IL-6 in moderate and severe COVID-19 cases. In a cross-sectional study, 81 patients meeting inclusion criteria were examined at a leading private COVID-19 referral hospital in Malang Regency. Data from clinical records and lab results encompassing blood counts, D-dimer, and IL-6 levels were collected. D-dimer was assessed through immunoturbidimetry (STA-Procoag-PPL, Diagnostica Stago S.A.S.), while IL-6 was measured using a chemiluminescent immunoassay (Cobas e411 Elecsys, Roche). Data distribution normality was assessed using Kolmogorov-Smirnov and Shapiro-Wilk tests. Non-normally distributed data were analyzed using the Mann-Whitney U test for numerical data and the Fisher exact test for comorbidity-severity correlation. Moderate COVID-19 cases disproportionately affected females, while severe cases had an even gender distribution. The median age was comparable, but mild cases were typically younger. Hemoglobin, hematocrit, leukocyte, neutrophil, platelet, and procalcitonin levels were normal in both groups, with lowered lymphocyte counts. Severe cases displayed a higher Neutrophil-to-Lymphocyte Ratio (NLR). D-dimer and IL-6 were significantly elevated in extreme cases. This study underscores potential gender and age-related discrepancies in COVID-19 severity, emphasizing the significance of monitoring specific blood parameters for disease progression indicators. Further investigation is vital to unveil underlying mechanisms and clinical implications, aiding the management of COVID-19 patients.
Room for uncertainty in infrastructure planning
Authors: Veenma Klaas , Leendertse Wim , Arts Jos
Published: November 2023

Infrastructure planning is increasingly confronted with a dynamic environment and an engaged society. This necessitates decision makers to interact with their environment, resulting in the adoption of adaptive and participative planning approaches such as combined infrastructure and (organic) area development (De Roo et al., 2020). Giving room to stakeholders and to unforeseen developments implies incorporating uncertainty in planning and decision making and increases the complexity of planning. In current infrastructure planning, decision makers seem to struggle to find a balance between giving room to uncertainties on the one hand, and keeping the decision-making process manageable on the other hand. This often results in attempts to reduce uncertainties, in 'certainification' (Van Asselt et al., 2007; Klijn & Koppenjan, 2016). This focus on certainification prevents adaptive and participative approaches in planning from reaching full maturity (Hajer et al., 2010; Albrechts, 2012).
Healthy urban food

Published: November 2023

Food is a territorial system closely linked to public health, social equity and land policy. Eating habits are at the root of both incidence of cardiovascular diseases and phenomena of malnutrition. Food often entails social inequity and is acquiring, directly and indirectly, ever greater relevance in the tools of territorial government.

The Cities2030 project is being developed, financed by the European Horizon 2020 programme. The methodology agreed upon by the partners envisages the involvement of all interest groups and actors of the food system arena, through the installation of urban Policy and Living Labs.

The University Iuav of Venice, is involved in the development of two Labs in the Veneto region: one in the city of Vicenza, the other in the Venice lagoon. Working in these two cases will make it possible to reflect on very different food systems, even though they are geographically close.

Published: November 2023

Face recognition is one of the most popular methods currently used for biometric systems. The selection of a suitable method greatly affects the reliability of the biometrics system. This research will use Deep learning to improve the reliability of the biometric system and will compare it with the SVM method. The Deep Learning method will be adopted using the Siamese Network with the YoloV5 detection method as a real-time face detector. There are two stages in this research: the registration process and the recognition process. The registration process is image acquisition using YoloV5. The image result will be saved in the storage folder, and the preprocessing and training process will use the Siamese Network. The face feature model will be stored in the database. The recognition process is the same as the registration, but the feature extraction result will be embedded and compared with the already trained models. The accuracy rate using the Siamese model was 94%.

Waktu Tunggu pelayanan resep adalah lamanya waktu yang dihitung mulai pasien menyerahkan resep kepada petugas farmasi sampai dengan obat diterima oleh pasien. Berdasarkan standar pelayanan minimal, waktu tunggu pelayanan resep obat jadi yaitu ≤30 menit dan obat racikan yaitu ≤60 menit. Tujuan dalam penelitian ini adalah menganalisis waktu tunggu pelayanan di instalasi farmasi rawat jalan di Rumah Sakit Islam Siti (RSI) Rahmah Padang. Metode yang digunakan dalam pengumpulan data adalah wawancara mendalam dan observasi. Pengambilan sampel dilakukan dengan teknik purposive sampling kepada informan kunci. Berdasarkan hasil penelitian menunjukkan bahwa waktu tunggu pelayanan farmasi rawat jalan RSI Siti Rahmah belum sesuai dengan standar. Rata-rata waktu tunggu mendapatkan obat racikan 2 jam 3 menit 3 detik, untuk waktu tunggu obat jadi adalah 1 jam 27 menit. Hal yang menjadi penghambat lamanya waktu tunggu adalah kurangnya jumlah sumber daya manusia, dokter yang tidak bisa dihubungi untuk konfirmasi resep serta adanya kendala alat. Dalam kegiatan pelayanan di instalasi farmasi sering ditemukan kendala pada lumpang, timbangan digital yang error, blender yang tidak berfungsi. Diharapkan rumah sakit segera melakukan rekruitmen untuk menambah tenaga kefarmasian serta melakukan pengajuan untuk penambahan alat dan melakukan pemeliharaan rutin.

Adding tiotropium or long-acting β2-agonists to inhaled corticosteroids: Asthma-related exacerbation risk and healthcare resource utilization
Authors: Hanania Nicola A. , Settipane Russell A. , Khoury Samir , Shaikh Asif , Dotiwala Zenobia , Casciano Julian , Foggs Michael B.
Published: November 2023

Background: Based on current clinical guidelines, long-acting β2-agonists (LABA) are frequently prescribed before long-acting muscarinic antagonists (LAMA) as an add-on to inhaled corticosteroids (ICS) in uncontrolled asthma. However, there is insufficient real-world
evidence that supports this therapeutic approach. Objective: The objective was to compare asthma exacerbations and healthcare resource utilization in patients with asthma using the LAMA tiotropium bromide (Tio) or a LABA as an add-on to ICS (ICS + Tio or ICS/LABA) in a
real-world setting. Methods: This retrospective, observational study included patients aged ≥12 years with asthma diagnoses identified in a U.S. longitudinal claims database (October 2015 to August 2020). The ICS + Tio and ICS/LABA cohorts were 1:2 propensity score matched
for baseline variables. Outcomes were compared in the postmatched cohorts, and the risk of exacerbation was evaluated by using Kaplan-Meier curves. Results: After propensity score matching, there were 633 and 1266 patients in the ICS + Tio and ICS/LABA cohorts, respectively.
The proportion of patients who experienced a severe or a moderate-or-severe exacerbation during follow-up was similar between the ICS + Tio versus ICS/LABA cohorts (4% versus 3%, p = 0.472, and 50% versus 45%, p = 0.050, respectively). The mean time to first severe (ICS + Tio 43.8 days versus
ICS/LABA 49.4 days, p = 0.758) and moderate-or-severe exacerbation (ICS + Tio 65.8 days versus ICS/LABA 58.9 days, p = 0.474) was not statistically different between cohorts. The treatments had no effect on the risk of severe exacerbation, although it was 36% lower in ICS + Tio users than
in ICS/LABA users (hazard ratio 0.64 [95% confidence interval, 0.22‐1.84]). All-cause and asthma-related average monthly healthcare resource utilization were comparable between the treatments for hospitalizations and emergency department visits but were significantly greater in the
ICS + Tio cohort than in the ICS/LABA cohort for asthma-related outpatient visits (p < 0.0001). Conclusion: This study provides real-world evidence that ICS + Tio may be a valid alternative when ICS/LABA cannot be used as first-line treatment for asthma maintenance therapy.
Utopian Vision and Its Double: An Allegorical Portrait of Black Life in Hurston’s One-act Play Mr. Frog
Authors:   Institute of British & American Studies Center for International Area Studies Hankuk University of Foreign Studies, Park Jungman
Published: November 2023

Zora Neale Hurston was an anthropologist and a woman writer participating in the African American literary movement known as the Harlem Renaissance in the 1920s. A prolific and versatile writer, she wrote a number of plays, and, in particular, devoted herself to creating ‘black folk comedy’ as a form of ‘the new and the real Negro theatre’ that honestly showed the language and daily life of black people in South Florida. This study focuses on Herston’s one-act play Mr. Frog as an example of black folk comedy. A fable story, the short dramatic skit represents the utopian model of coexistence and symbiotic community by portraying the lives of animals. On the other hand, this utopia created on stage is a space that does not exist in reality, so in return, it indirectly suggests ‘other’ picture hidden behind the surface, namely, the portrait of contemporary black people in South Florida living the harsh reality of racism. In the play, the utopian vision is presented as ‘double’ and this writing strategy meets the nature and effects of an allegorical narrative deriving from the correlation of surface text and the hidden meaning or subtext. This study concludes that Mr. Frog, through the fable story of animals, dramatizes the ‘double’ of the utopian vision that diverges into the ideal community for coexistence and the reality of black life, thereby suggesting a model for allegorical playwriting.
Shame and Guilt As Sanctions Controlling Gawain’s Behavior
Authors:   Institute of British & American Studies Center for International Area Studies Hankuk University of Foreign Studies, LEE Dongchoon
Published: November 2023

Sir Gawain and the Green Knight is a valuable work for the study of honor and shame in late-medieval English literature. In addition to the social codes influenced by pre-Christian “shame culture”, the “guilt culture” deeply embedded in the work is also crucial to the understanding of the Gawain poet’s intention as well as Sir Gawain’s behavioral modes. The shame culture is the performative public honor, which exerts the strongest influence upon Sir Gawain for the first half of the poem. After his departure from the Arthurian court, Sir Gawain’s actions are circumscribed by both guilt and shame ideologies. Gawain’s ending creates the shift from upholding the chivalric ideals of a romance hero based upon shame culture to a guilt culture whose emphasis lies on Sir Gawain’s interior thoughts and personal moralities closely linked with the Christian doctrines. The move from shame culture to guilt culture results from the Gawain poet’s realistic vision toward the chivalry of the late medieval age and his awareness of the social changes such as the advent of individualism, and the need for personal confession.
Aftbody Heat Flux Measurements During Mars 2020 Entry

Published: November 2023

The Mars Entry, Descent, and Landing Instrumentation 2 (MEDLI2) sensor suite on the Mars 2020 mission included two total heat flux sensors and one radiometer on the backshell to directly measure the aftbody aerothermal environments during entry into the Martian atmosphere. All three sensors successfully returned aftbody entry heating measurements. Comparisons between the total heat flux sensor measurements and predictions by NASA simulation tools (DPLR/NEQAIR) show excellent agreement and provide confidence in the models. The radiometer measured significant radiative heating, but compared to the model predictions the signal was attenuated by 48% at the end of the entry heat pulse. The loss of signal is attributed to blockage by thermal protection system (TPS) ablation product deposits on the radiometer window. Ground-based testing in the NASA Ames arcjet facilities was conducted to understand the impact of ablation product deposits on the measured radiometer signal. A discussion of the test results, how flight-like the test conditions were, and future work to further characterize the effect of TPS ablation product deposits on the radiometer performance are presented. In addition to measuring the entry heat pulse, all three sensors were sensitive enough to measure solar radiation during cruise, the radiometer measured solar flux during the entry heat pulse, and the leeside total heat flux sensor picked up the descent reaction control system firings.
Strategic Deconfliction of Unmanned Aircraft Based on Hexagonal Tessellation and Integer Programming
Authors: Liu Yanchao , Zhou Zhenyu , Naqvi Waseem , Chen Jun
Published: November 2023

Unmanned aircraft systems service suppliers adhere to interoperability standards that require unmanned aircraft operators to submit an operational intent, which describes the planned flight path in four-dimensional space. To ensure fairness, the central database follows a first-come, first-served approach, accepting new operational intents as long as they do not conflict with any active ones. However, creating a viable operational intent is challenging due to moving obstacles. This paper introduces an innovative optimization-based procedure to automate the intent filing process. It utilizes a stacked hexagonal tessellation to model the airspace, offering adjustable granularity. Path finding is accomplished using integer programming on the hex grid. The integer program is solved on a grid canvas that includes only necessary cells, striking a balance between computational efficiency and optimality. Simulation experiments demonstrate the procedure’s effectiveness in generating feasible trajectories, even in scenarios with dense, omnidirectional air traffic. This procedure has the potential to become the foundational software core for low-altitude air traffic management systems, providing strategic deconfliction and constraint management services.
Air Interactions of Magnetically Driven Plasma Discharges in Crossflow

Published: November 2023

Motivated by the use of magnetohydrodynamic devices in fluid dynamic flow control research, the current work experimentally studied the actuation mechanism and the resulting aerodynamic interactions of magnetically driven low-current arc-plasma discharges. The investigation was conducted in the context of boundary-layer interactions in low-speed crossflow conditions through the use of coaxial and v-shaped geometries. Time-averaged velocity field measurements showed that the toroidal region of vorticity induced by the coaxial geometry in quiescent air resulted in the formation of a horseshoe vortex in crossflow. Similarly, the v-shaped actuator resulted in the formation of streamwise vortices. The resulting boundary layers had s-shaped streamwise velocity profiles as measured in the wall-normal direction characteristic for the flow downstream of a conventional vortex generator pair, due to the three-dimensional mixing induced by coherent vortex structures. A simplified model based on intermolecular momentum transfer through collisions is proposed to explain the fundamental discharge–air interactions and the induced flowfields. These results inform the applications of various magnetically driven discharges in the field of aerodynamic flow control.

It would often be in the public interest for persons with special knowledge, including the so-called liberal profession-als, to exercise their skills voluntarily, as long as a need for their services arises: for example, a healthcare practitionerwould provide treatment to anyone in need of emergency care, architects would act as soon as there is a mention ofa crack in the load-bearing wall of an apartment building and judges would judge a court on holidays if need arises.But the legal duty to act can be demanded from those who are legally assigned this task only. For all the stakeholders,legal certainty in healthcare is an issue of major importance. To contribute to this aspect, this study aims to detect thelegal and ethical framework of the medical practitioner’s obligation to provide treatment outside of working hours. Thescientific literature, case-law, legal acts and court judgements were studied; the analytic, doctrinal, comparative andmodelling methods were applied; the general legal norm interpretation methods were used. The authors conclude thatoutside of working hours, medical practitioners are exempt from their legal responsibilities, are guided by moral normsand general citizens’ obligations only and have the right to refuse to provide professional healthcare services. Theinconsistency among legal scholars and legal and medical practitioners concerning the duties of healthcare profes-sionals during their rest time was detected. The recommendations are proposed to ensure legal certainty and achieveconsentaneity among the stakeholders.

Background:

Hereditary multiple osteochondromas (HMOs) are a rare genetic disorder characterized by the formation of multiple benign osteochondromas that can undergo malignant transformation into chondrosarcoma.

Case Description:

A 24-year-old male with a history of HMO and osteochondroma surgery 4 years ago, presented with back pain and paresthesias. The magnetic resonance showed a right paravertebral infiltrating mass at the T12–L1 level causing spinal cord compression. Following en bloc resection of the tumor, the patient’s symptoms/ signs resolved. The final pathological diagnosis was consistent with a chondrosarcoma.

Conclusion:

Chondrosarcomas secondary to HMO with spinal cord compression are rare. These patients often presenting with significant myelopathy/cord compression should undergo gross total resection where feasible to achieve the best outcomes.

Two-dimensional (2D) materials represent the ultimate limit of miniaturization along the vertical direction, where several fascinating quantum mechanical effects—that are otherwise inaccessible—appear, generating widespread interest in fundamental and applied research. However, the preparation of scalable monolayers is a requirement that is hindered because of the lack of suitable synthesis and manipulation techniques. Here, we report a facile approach for obtaining bulk-crystal-sized 2D monolayers with a yield of almost 100% under ultra-high vacuum (UHV) conditions. We have exfoliated MoS2 on Au and Ag substrates to demonstrate the exfoliation process, where the spectroscopic measurements suggest a very strong dispersive interaction between the metal substrate and MoS2, resulting in a high strain field on the topmost layer of the bulk crystal, which is substantially relaxed in the subsequent layer. This vertically inhomogeneous distribution of the strain field reduced the magnitude of interlayer van der Waals interactions, resulting in the high selectivity of monolayer exfoliation. Along with the scalable exfoliation of monolayers, our method also paves a route to obtain 2D monolayers of materials that are unstable under ambient conditions.

We have investigated the chemical lithiation in 70 nm cubic-shaped magnetite nanoparticles with varying degree of lithiation x = 0, 0.5, 1, 1.5. The induced changes on structure and magnetic properties were investigated with X-ray scattering techniques along with electron microscopy and magnetic measurements. The results indicate that a structural transformation from spinel to rock salt phase occurs above a critical limit for the lithium concentration (xc), which is determined to be between 0.5< xc≤1 for Fe3–δO4. Magnetization measurements confirm the formation of the LiFeO2 phase with its distinct antiferromagnetic behaviour. Upon lithiation, exchange bias measurements reveal a shift in the hysteresis loops with an asymmetry, which can be attributed to the formation of mosaic-like LiFeO2 subdomains and cationic disorder. The combined structural, spectral-imaging and magnetization characterization techniques enabled us to identify the phases and their distribution during in the lithiation process.
PEOPLE AND POWER IN “BORIS GODUNOV” BY A.S. PUSHKIN AND “DIMITRY THE IMPOSTOR” BY F. V. BULGARIN
Authors: Подгорная Е.Г.
Published: November 2023

В статье рассматривается тема борьбы народа и власти в драме А. С. Пушкина «Борис Годунов» и романе Ф. В. Булгарина «Димитрий Самозванец». В основе обоих произведений лежит идея о том, что преступление монарха неизменно влечет за собой народные несчастья и волнения, но способы развития этой идеи значительно отличаются.

The article considers the theme of the struggle between the people and the power in A. S. Pushkin’s drama “Boris Godunov” and F. V. Bulgarin’s novel “Dimitry the Impostor”. Both works are based on the idea that the monarch’s crime invariably entails people’s misfortunes and unrest, but the ways of developing the idea differ significantly.

Hệ thống quản lý học tập (Learning Management System, hay còn gọi là LMS) được xem là một công cụ hữu ích giúp hỗ trợ quá trình dạy học trực tuyến, đặc biệt là ở các cơ sở giáo dục đại hoc. Bài báo trình bày các kết quả nghiên cứu nhằm tìm hiểu về thực trạng sử dụng LMS trong dạy học trực tuyến tại Trường Đại học Ngoại ngữ, Đại học Huế. Một khảo sát đã được tiến hành với sự tham gia của 14 giảng viên và 130 sinh viên Khoa Tiếng Anh để tìm hiểu việc sử dụng và ý kiến đánh giá của họ đối với LMS trong thời gian phải học trực tuyến vì giãn cách xã hội. Kết quả nghiên cứu cho thấy, giữa giảng viên và sinh viên có sự tương đồng trong thói quen truy cập vào LMS xét về tần suất, thời gian và việc sử dụng ứng dụng di động. Tuy nhiên, có sự khác nhau rõ ràng về các hoạt động trên LMS mà giảng viên và sinh viên thường xuyên sử dụng trong quá trình dạy học trực tuyến. Giữa giảng viên cũng có sự khác nhau nhất định trong quá trình sử dụng LMS khi so sánh dựa trên kinh nghiệm giảng dạy và chuyên môn giảng dạy, trong khi đó không có sự khác biệt rõ ràng nào giữa sinh viên với nhau. Ngoài ra, cả giảng viên và sinh viên nhìn chung đều hài lòng về hầu hết các khía cạnh của LMS bao gồm giao diện, chức năng, cách tổ chức sắp xếp khóa học v.v. Tuy nhiên, cả giảng viên và sinh viên đều chưa đánh giá cao tốc độ xử lý thông tin cũng như tính ổn định của LMS.

The hERG1 potassium channel is aberrantly over expressed in tumors and regulates the cancer cell response to integrin-dependent adhesion. We unravel a novel signaling pathway by which integrin engagement by the ECM protein fibronectin promotes hERG1 translocation to the plasma membrane and its association with β1 integrins, by activating girdin-dependent Gαi3 proteins and protein kinase B (Akt). By sequestering hERG1, β1 integrins make it avoid Rab5-mediated endocytosis, where unbound channels are degraded. The cycle of hERG1 expression determines the resting potential (Vrest) oscillations and drives the cortical f-actin dynamics and thus cell motility. To interpret the slow biphasic kinetics of hERG1/β1 integrin interplay, we developed a mathematical model based on a generic balanced inactivation–like module. Integrin-mediated cell adhesion triggers two contrary responses: a rapid stimulation of hERG1/β1 complex formation, followed by a slow inhibition which restores the initial condition. The protracted hERG1/β1 integrin cycle determines the slow time course and cyclic behavior of cell migration in cancer cells.
Late Payment Fees and Nonpayment in Rental Markets, and Implications for Inflation Measurement: Theoretical Considerations and Evidence
Authors: Janson Wesley R. , Verbrugge Randal J.
Published: November 2023

Accurate rent measurement is essential for constructing a consumer price index (CPI) and for measuring household welfare. Late payment fees and nonpayment of rent are common components of rental expenditures and thus belong in CPIs. Late payment fees are often excluded; we offer a novel critique. In the US CPI, nonpayment is ostensibly included, but, we show, severely undermeasured. Moreover, the manner of its inclusion renders the CPI extremely sensitive to nonpayment variations; we show how to fix this. Nonpayment undermeasurement suggests at least a +1 ppt overestimate in 2020 CPI shelter inflation. Timely nonpayment and late fee measurement is challenging; we offer a practical solution.
