Opis:
Facing climate change, global warming and the depletion of fossil resources such as coal, oil, etc., the development of clean energy sources has become a global trend. Clean energy sources are being exploited and strongly developed globally today, including: solar energy, wind energy, geothermal energy, ocean wave energy, geothermal energy, biomass energy . Vietnam is located in the tropical monsoon climate, with a coastline stretching over 3,000 km, so the potential for wind energy development in Vietnam is extremely large, attracting a lot of investment in wind power projects in Vietnam. current and future, including wind power plant project No. 3 – Soc Trang province. So far, we have only mentioned the benefits and clean, renewable aspects of wind power, but few have mentioned the environmental and human health impacts of wind power plants, especially noise during operation. The paper uses WindPro software 3.1.597 to determine the extent of influence caused by noise emitted by wind turbines during the operation of wind power plants, thereby assessing its impacts on people's health. local people living around the project area and propose remedial measures
W obliczu zmian klimatu, globalnego ocieplenia i wyczerpywania się zasobów kopalnych, takich jak węgiel, ropa naftowa itp., rozwój czystych źródeł energii stał się światowym trendem. Czyste źródła energii są obecnie eksploatowane i silnie rozwijane na całym świecie, w tym: energia słoneczna, energia wiatru, energia geotermalna, energia fal oceanicznych, energia geotermalna, energia biomasy. Wietnam położony jest w tropikalnym klimacie monsunowym, z linią brzegową rozciągającą się na ponad 3000 km, więc potencjał rozwoju energetyki wiatrowej w Wietnamie jest niezwykle duży, co przyciąga wiele inwestycji w projekty wiatrowe w kraju. Przykładem omawianym a artykule jest elektrownia wiatrowa nr 3 – prowincja Soc Trang. Jak dotąd wspomnieliśmy tylko o korzyściach i czystych, odnawialnych aspektach energii wiatrowej, ale niewielu wspomniało o wpływie elektrowni wiatrowych na środowisko i zdrowie ludzi, a zwłaszcza emisji hałasu podczas pracy. W artykule wykorzystano oprogramowanie WindPro 3.1.597 do określenia stopnia oddziaływania hałasu emitowanego przez turbiny wiatrowe podczas pracy elektrowni wiatrowych, oceniając tym samym jego wpływ na zdrowie ludzi, lokalnych mieszkańców mieszkających w pobliżu obszaru objętego projektem i zaproponować środki zaradcze.

Opis:
This essay delves into the concept of Theory Y, one of the hallmark relationship management principles of the 20th century introduced by Douglas McGregor in his influential book "The Human Side of Enterprise" (1960). Theory Y assumes that employees are self-motivated, seek responsibility, and do not dislike work. The essay explores the advantages and disadvantages of Theory Y, highlighting its potential in nurturing creativity and maintaining employee satisfaction, but also addressing its limitations in certain situations. It examines successful examples of Theory Y implementation in companies like Facebook and Google, as well as the potential drawbacks such as freedom abuse and lack of organizational control. Additionally, the essay discusses the relationship between Theory Y and its counterpart, Theory X, which represents a more traditional, directive management style. By examining both theories, the essay emphasizes the importance of carefully considering and adapting management approaches based on the specific context and needs of an organization.

Opis:
The high-speed of train (HST) in combination with the high carrier frequency of HST systems leads to the severe inter carrier interference (ICI) in the HST orthogonal frequency division multiplexing (HST-OFDM) systems. To avoid the complexity in OFDM receiver design for ICI eliminations, the OFDM system parameters such as symbol duration, signal bandwidth, and the number of subcarriers should be chosen appropriately. This paper aims to propose a process of HST-OFDM system performance investigation to determine these parameters in order to enhance spectral efficiency and meet a given quality-of-service (QoS) level. The signal-to-interference-plus-noise ratio (SINR) has been used as a figure of merit to analyze the system performance instead of signal-to-noise ratio (SNR) as most of recent research studies. Firstly, using the non-stationary geometry-based stochastic HST channel model, the SINR of each subcarrier has been derived for different speeds of the train, signal bandwidths, and number of subcarriers. Consequently, the system capacity has been formulated as the sum of all the single channel capacity from each sub-carrier. The constraints on designing HST-OFDM system parameters have been thoughtfully analyzed using the obtained expressions of SINR and capacity. Finally, by analyzing the numerical results, the system parameters can be found for the design of HST-OFDM systems under different speeds of train. The proposed process can be used to provide hints to predict performance of HST communication systems before doing further high cost implementations as hardware designs.

Opis:
Objectives: to analyze changes in knowledge and practices regarding silicosis in groups of workers at high risk of silicosis before - after an intervention. Methods: The study was conducted from 2018 to 2019 based on structured questions related to knowledge and practices of silicosis of workers directly exposed to silica dust in a Northern province of Vietnam. The mobile app-based intervention was applied to steel workers, then compared with ironworkers in improvements in silicosis knowledge and practices. Results: Significant changes in the intervention group related to workers' knowledge about the signs suggestive of silicosis, disease consequences, measures to reduce the risk of silicosis, and participation in annual occupational disease examinations were reported. Conclusion: Mobile applicationbased interventions could improve silicosis knowledge and practice among workers at high risk of exposure to silica dust.

Opis:
The studFigy aims to determine the TNF-α single-nucleotide polymorphism TNF-α (-308) and assess the association of TNF-a(-308) SNP with the risk of silicosis among workers directly exposed to silica dust in Vietnam. A study was undertaken among 78 cases with silicosis and 103 controls without silicosis in Vietnam. Blood samples were collected for genomic DNA extraction from each subject. The phenotyping of TNF-α(-308) was performed using polymerase chain reaction‐based restriction fragment length polymorphism (PCR‐RFLP) and dye termination sequencing. Results: The average exposure time of the case group was slightly higher than that of the control group (12.46 ± 6.732 years vs. 12.09 ± 7.854 years). The majority of genotypes in both silicosis and non-silicosis was GG. When analyzing the concentration of TNF-α in the study participants' blood, it is shown that the average concentration of TNFα in the case group was higher than that in the control group. The genotype AG in the case group was 1.368 times higher than that in the control group. The percentage of all A alleles in the case group with silicosis was 1.342 times higher than the control group without the disease, similar to previous studies. Conclusion: The majority of genotypes in both groups was GG. The average concentration of TNF-α in blood, genotype AG, and the percentage of all A alleles in the case group was higher than that in the control group.
