Published: June 2024

This study aimed to identify factors that related with sleep disturbance among older people with dementia in nursing homes. This cross-sectional study included 140 participants aged 60 years old and over, who were diagnosed with dementia (according to DSM 5 criteria) from November 2022 through January 2023 in 3 nursing homes in Hanoi, Vietnam. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The mean (SD) age among participants was 78.23 (8.73) and the female/male ratio was 1.5. The prevalence of poor sleep was 76.4% (n = 107). The poor sleep was significantly associated with depression (p = 0.007). The prevalence of poor sleep quality among the older people in nursing homes is relatively high. Depression is related to poor sleep quality among participants. Therefore, evaluating sleep quality among nursing homes should be performed as a basic clinical practice.

Published: June 2024

The purpose of this study was to determine the prevalence and associated factors of gestational diabetes mellitus (GDM) in the Mekong Delta region. A multicenter, cross-sectional descriptive study was conducted on 1727 pregnant women undergoing oral glucose tolerance testing (OGTT) at 4 major central hospitals of 4 provinces in the Mekong Delta region from 06/2017 to 06/2022. Results: Among 1727 pregnant women undergoing OGTT, the overall prevalence of GDM is 17.1% (296/1727), and the prevalence in 4 provinces ranges from 15.4 to 19.0%. Multivariate logistic regression analysis revealed 10 associated factors increasing the risk of GDM, including maternal age ≥ 25, Kinh ethnicity, urban residence, lower than high school education, family history of diabetes in the first generation, BMI ≥ 25 kg/m2, weight gain ≥ 12kg, history of miscarriage, history of delivering babies ≥ 4000g, and prior GDM history (p ≤ 0.05). Conclusion: The prevalence of GDM in the Mekong Delta region is nearly 1/5 of pregnant women, so screening for GDM should be routinely conducted for all pregnant women between 24 and 28 weeks of gestation, particularly those with risk factors associated with an increased risk of GDM.

Purpose

Executive function impairments are among the most common dialysis side effects. The present study aims to compare the efficiency of transcranial Direct Current Stimulation (tDCS) with computerized Cognitive Rehabilitation Training (cCRT) on dialysis patients’ executive functions.

Research method

The present study, a quasi-experimental effort, adopted a pre-test/post-test method that included a control (sham) group.

Design

The study sample consisted of 30 participants, selected through the convenience sampling method, and categorized into three groups of cCRT, tDCS, and sham participants. The cCRT participants were asked to complete 8 tasks in Captain’s Log MindPower Builder software. The tDCS participants were treated with a 0.06 mA/cm2 current with the anodal electrode on F3 and the cathodal electrode on Fp2. For the sham participants, the electrodes were put on the same regions but there was no current stimulation. The treatment lasted for 10 sessions carried out every other day.

Results

The results of MANCOVA showed no significant difference between the sham group and the cCRT group in any of the executive function items. . However, between the sham group and the tDCS group was detected a significant difference in spatial working memory (p < 0.05) and a marginally significant in cognitive flexibility (p = 0.091). No significant difference was reported between cCRT and tDCS groups in any item.

Conclusion

According to the findings of the study, given the efficacy of tDCS on spatial working memory and cognitive flexibility for dialysis patients, it can be used to improve these skills.

因醫院高樓化、電氣配管複雜及病人受限於透析管路連接著機器易導致逃生困難，單位於2020年8月進行火災撤退演練，撤退時間為28分鐘17秒，高於消防署規定的21分鐘。故成立專案小組進行改善，分析確立問題為沒有參與過火災緊急應變撤退實際演練、撤退逃生路線標示不清、衛教指導後未確實評值病人的了解程度、相關衛教指導工具不足。執行期自2020年9月1日至2021年1月31日，為期5個月，依計劃期、執行期及評值期三階段進行，介入措施包含舉辦火災緊急應變撤退實際演練、製作撤退動線夜光引導標示、規範火災緊急應變撤退認知及技能稽核標準、製作火災緊急應變撤退小卡、衛教單張、教學影片及透析管路分離作業流程。專案實施後，病人對火災緊急應變撤退的認知由改善前的42.0%提升至改善後的88.4%，而撤退技能由改善前的38.9%提升至改善後的88.0%。撤退時間亦由28分鐘17秒縮短為19分鐘50秒。使病人在火災發生時，更有助於確保自身生命安全。

 

Difficulty in evaluation is considered due to the high-rise building of the hospital, the complicated electrical piping, and the fact that patients during hemodialysis are limited by the dialysis machines. A fire drill was conducted in August 2020, and the evacuation time was 28 minutes and 17 seconds. It is higher than the 21 minutes stipulated by the fire department. Therefore, a task force was formed to make improvements. After analyzation, we found several problems to be solved. First of all, patients had not participated in actual fire evacuation drill. Second, the evacuation routes were not clearly marked. Third, patients’ understanding was not adequately evaluated after our health education guidance. Fourth, the relevant health education guidance tools were insufficient. The implementation period is from September 1, 2020 to January 31, 2021, for a period of 5 months, in three stages: planning period, implementation period and evaluation period. Therefore, improvement measures was conducted, including holding actual fire drill with emergency evacuation, making luminous evacuation sign for escape routes, regulating auditing standards of cognitions and skills for evacuation, making emergency evacuation photocards, health education guidance leaflets and videos, and establishing operationg procedures of dialysis equipment separation. After the implementation of the project, the cognition improvement of patients about the emergency evacuation of fire was from 42.0% to 88.4%, and the skills of evacuation was from 38.9% to 88.0%. Furthermore, the evacuation time shortened from 28 minutes and 17 seconds to 19 minutes and 50 seconds. Eventually, it is more helpful for patients to ensure their own safety in the event of a fire.

Published: June 2024

In today's technologies, automation is expanding quickly. Therefore, Automation is essential in the agriculture sector and beneficial to farmers. Grass cutters were manually operated portable instruments in former times. As a result, they used gas and petrol engines, which resulted in pollution and energy loss. Therefore, it is necessary to replace the old grass cutters with automated ones that use batteries as a power source for the system's guiding and obstacle detection. Additionally, It utilized a motor drive for the robot's wheels, a linear blade to cut the grass and using image processor for object detection, and an arm at the front of the rover to move the small obstacles which can protect the grass cutting blade and an Arduino UNO microcontroller board as the system's primary controller. A cordless electric lawn mower, which is self-powered by electricity, is another goal of the project. A Raspberry Pi microprocessor serves as the machine's brain and directs the movements of the lawnmower. It is made up of geared motors that manage the mover's speed and direction.and a high-torque motor that drives the cutting blades. The geared motors are switched on and off using a control circuit that is comprised of MOSFETS that are controlled by the raspberry pi. The mover has an onboard camera which is used by the microprocessor to detect objects and living beings and take the necessary action that being, to avoid themorstop moving.

Published: June 2024

Introducción. Las poblaciones del piojo harinoso Phenacoccus solenopsis se incrementaron en el valle de Mexicali, ocasionando pérdidas económicas en el cultivo de algodón (Secretaría de Agricultura, 2021). Además, se carecen de estudios del comportamiento poblacional de esta plaga en esta región del estado de Baja California. Objetivo. Estudiar la fluctuación poblacional de P. solenopsis en el cultivo de algodón en el valle de Mexicali. Métodos. Se realizaron muestreos semanales (abril-septiembre de 2019) en una parcela de algodón de 5 000 m2 en el ejido Querétaro del valle de Mexicali. Se empleó el muestreo sistemático seleccionando un punto de muestreo cada 10 m, se revisaron un total de 400 plantas por día de muestreo, se consideró una planta infestada si presentaba al menos un piojo harinoso (Negrare et al., 2011). Se monitorearon las condiciones climáticas del área experimental durante el periodo de estudio. Se realizó análisis de correlación para conocer el grado de relación entre las condiciones climáticas y el número de plantas infestadas. Resultados y discusión. Se observó que durante los meses de abril, mayo y junio no se detectó a P. solenopsis en el área de estudio. Se detectó a finales de junio y durante el mes de julio que su densidad fue baja. En los meses de agosto y septiembre P. solenopsis registró su mayor incremento poblacional alcanzando 16 plantas infestadas por fecha de muestreo. El análisis de correlación indicó una relación directamente proporcional (r=0.414, P= 0.0698) entre la temperatura y el número plantas infestadas, sugiriendo que a mayor temperatura mayor incremento poblacional de la plaga. Por el contrario, la relación entre la radiación fue inversamente proporcional (r= -0.338, P= 0.1448), indicando que a mayor radiación menor densidad poblacional de P. solenopsis. Conclusión. La mayor incidencia de P. solenopsis en el valle de Mexicali se presentó en los meses de agosto y septiembre. Las altas temperaturas incrementaron la densidad poblacional de la plaga y la alta radiación la disminuyó.

In recent years, methods of extracorporeal detoxification using carbon materials have received due recognition and widespread development. Carbon materials for blood detoxification based on coal have firmly taken a dominant position among sorption materials. This is due, first of all, to the fact that carbon sorbents have wide possibilities for selecting the required physicochemical and structural sorption characteristics. It has been established that a single oral administration of biomass to rats at a dose of 75 mg/kg does not cause any signs of intoxication. At the same time, no animal deaths were recorded throughout the entire observation period. There were no gender differences in the sensitivity of rats to the action of the drug. Due to the lack of mortality in the dose range studied, the lethal doses of LD100 and LD50 could not be determined.

Published: June 2024

Vegetables are one of the essential foods in human daily life. Due to the short shelf life, it is difficult to preserve, the supermarket needs to timely and reasonable purchases and pricing. This paper aims to establish a model that can predict vegetable price fluctuations and develop reasonable pricing and replenishment strategies. According to the data given from a wet market, this paper studies the pricing and replenishment decisions of supermarket vegetables. By establishing the SARIMA model and Markov forecast model, the wholesale price of the same project on July 1 is calculated based on the wholesale price forecast of the previous week, and reasonable market demand is predicted. It is found that the predicted results have a reasonable error with the actual situation, and the accuracy is relatively high. The establishment of these two models is of great significance for market regulation. The model has good predictability and practical value, with good dynamic predictive ability, suitable for a reasonable allocation of resources in supermarkets and other trading places to obtain maximum benefit.
Managerial myopia and audit fees: Evidence from China
Authors: Wang Tianyi
Published: June 2024

Following the upper echelons and time orientation theoretical frameworks, this study meticulously examines the effects of managerial myopia on audit fees utilizing data of Chinese A-share listed companies spanning from 2007 to 2022. Employing textual analysis and machine learning techniques on MD&A, we find that managerial myopia can significantly increase audit fees by intensifying financial constraints, diminishing accounting information comparability, and compromising internal control quality. However, this relationship is accentuated by analyst coverage but attenuated by digital transformation. Cross-sectionally, we document a particularly pronounced positive association between managerial myopia and audit fees within firms exhibiting higher corporate risk tolerance, diminished industrial competition and a lower degree of marketization. Collectively, this study further enriches corporate governance and audit fees literature, advancing valuable insights for regulators, accountants and auditors.

Can State-owned Shareholders' Participation Curb Stock Price Crash Risk? --Based on Empirical Evidence of A-share Private Listed Companies from 2008 to 2019
Authors: Li Ruiyi
Published: June 2024

After state-owned shareholders buy shares in private listed companies, they will more or less bring about some changes in the development of private listed companies. The existence of state-owned shareholders can enable listed companies to obtain more resources, which will play a certain role in promoting the company's operation. These favorable conditions will also attract more attention from the outside world. In order to study whether these changes will affect or restrain the company's stock price crash risk during the company's development, we take the stock price data of private listed companies in A-shares from 2008 to 2019 as the object of analysis. This paper studies the influence of state-owned shareholders' participation on the risk of stock price collapse of private companies. Through the regression model analysis, it is found that there is a significant negative correlation between the state-owned shareholders' participation in the private listed company and the company's stock price crash risk, that is, the state-owned shareholders' participation in the private listed company can significantly restrain the company's stock price crash risk.

Functional Principal Component Regression Model Based on FIrst-order Boosting and Model Averaging
Authors: Huang Yifan
Published: June 2024

Functional regression model has always been an important research direction in the field of functional data analysis, in which functional principal component analysis as a common method of functional regression modeling, the determination of the number of truncations of the eigenfunctions has always been a problem to be solved. Based on this, this paper proposes a functional principal component regression model based on the idea of model averaging, which uses Bayesian model averaging instead of model selection, determines the number of truncations adaptively and balances the prediction error with the training error. In addition, the original function curves do not effectively capture the information of their functional characteristics. In this paper, the first-order derivative function is used as the supplementary information of the original function curve to jointly characterize the predictor variables. In the efficiency test, this paper averages the Bayesian model as the benchmark model and conducts real data analysis on several benchmark datasets. The results show that the proposed method has higher predictive accuracy and robustness than commonly used models.

This study investigates the variables that affect and encourage inbound travel to Hong Kong using data from 2019 to 2020. Five important regional source markets for tourism in Hong Kong have been chosen, namely Singapore, Malaysia, Philippines, Japan, and South Korea. Based on the research results, the COVID-19 pandemic had a major destructive effect on Hong Kong's tourism sectors while significantly impact the quantity of inbound tourists due to government response to COVID-19 infection case. The quantity of inbound tourists to Hong Kong is significantly impacted by the government's actions based on the COVID-19 infection cases. Additionally, existence of COVID-19 in the tourism source countries is often considered when defining Hong Kong's travel restrictions. According to the empirical findings, the demand for visitor arrivals was also lowered by the distance to Hong Kong and the expensive cost of travel there, while the expansion of tourism was facilitated by improved aviation services and potential for the tourism sector. These results demonstrate that for the city to be recognized as an attracting and cherished tourist destination, the tourism sector and the government must collaborate to restore after the pandemic. The complementary nature of pandemic control and tourist recovery is highlighted by this study. To establish a positive ripple effect, these operative and budgetary standards must demand the government to provide early recovery support to tourism sectors.

Authors: Zhou Shanhan
Published: June 2024

The world's population and economy have grown quickly, which has resulted in significant carbon dioxide emissions. People are concerned about the ensuing climate change and other problems. While there are now technologies that can lower alarming levels of greenhouse gas emissions, carbon dioxide capture is seen to be the most economical solution. Thus, it is essential to create efficient CO2 capture systems. Metal-organic frameworks (MOFs) have been demonstrated to be the most successful materials for CO2 collection and adsorption due to their microporous structure and advantageous properties, making them the most promising materials currently on the market. The basic properties of MOFs, such as their large surface area, chemical stability, adjustable pores, and porous structure, are initially outlined in this article. Next, the features of MOFs for separation were presented, particularly how well they could separate CO2 from gases like hydrogen, natural gas, and flue gas. Lastly, this research highlights the use of chemical functionalization, doping metals, and unsaturated metal centers to improve MOFs' adsorption and CO2 storage capabilities.
