Risk prevention and control strategies for the severely affected areas of snow disaster in the Three Rivers Source Region(TRSR), China

Historically,frequent and heavy snow disaster(SD)has caused serious livestock death and casualties,resulting in a devastating impact on animal husbandry development in the Three Rivers Source Region(TRSR).From winter in 2018 to spring in 2019,the largest SD occurred in this area over the past 10 years,especially in core zones of the Lancang River Source Region.Field research results show that the main causes of the major SD include weak infrastructure(i.e.,roads,communications,warm sheds,and insufficient forage reserve),low rate of domestic animals for sale before the SD,and low loss settlement rate.SD occurrence could furtherly reduce the ability of disaster prevention,mitigation and relief of disaster loss.In the future,heavily affected SD areas should improve the forecasting ability of snowfall incidents,strengthen infrastructure construction,implement grass and livestock balance strategies,optimize livestock structure,improve loss settlement rate,and develop a modern compound model of animal husbandry development model that combines breeding,slaughtering and deep processing of animal product.

Clinical Research of Pre-Hospital Emergency Care, Nursing, Infection Prevention and Control for Senile Osteoporotic Vertebral Compression Fracture during Epidemic Period

Background: Novel coronavirus pneumonia (NCP) and osteoporotic vertebral compression fractures (OVCF) are the high incidences of diseases in the elderly. During the epidemic period, if not treated in time, the complications are high and the mortality is high. If we do not pay attention to infection prevention and control in pre-hospital emergency care, it will lead to the first time infection of medical staff and in-hospital cross infection in emergency outpatient receiving area. The correct consideration of both and the establishment of perfect pre-hospital emergency treatment and infection prevention and control synchronous strategy is an important premise to ensure the stable, orderly and safe medical treatment. Objective: To explore the effect of synchronous implementation of pre-hospital emergency care, nursing and infection pre-vention and control for senile OVCF during the epidemic. In order to improve the efficiency of pre-hospital emergency care and prevent the spread of infection. Method: A total of 92 elderly patients with OVCF who received pre-hospital treatment in 18 hospitals in Zhangjiakou City during the epidemic prevention and control period from January 2020 to November 2022 and met the inclusion criteria were selected as research objects, including 24 males and 68 females, aged 65 - 82 (74.2 ± 2.2) years. All patients were associated with concomitant injuries and underlying diseases. All patients in this group underwent predictive pre-hospital rescue and infection prevention and control procedures. Results: All the 92 elderly patients with OVCF received timely pre-hospital treatment during the epidemic period, and no aggravation occurred of the 92 patients, 35 were in the high risk area, 10 were in the medium risk area, and 47 were in the low risk area. Exclude OVCF for NCP Patients were treated according to the conventional diagnosis and treatment principles. Suspected and confirmed cases are transferred to designated surgical hospitals for treatment. All patients were followed up 3 months, 6 months and 12 months after treatment. There was no death rate, high satisfaction of pre-hospital first aid, high diagnostic accuracy, and good curative effect. None of the rescue personnel had any infection rate, and no hospital infection transmission and nosocomial cross infection occurred. Conclusion: It is the first step to safely treat patients and prevent cross infection to establish a perfect synchronous strategy of pre-hospital first aid and infection prevention and control.

Risk Management of Clinical Reference Dosimetry of a Large Hospital Network Using Statistical Process Control

Managing TG-51 reference dosimetry in a large hospital network can be a challenging task. The objectives of this study are to investigate the effectiveness of using Statistical Process Control (SPC) to manage TG-51 workflow in such a network. All the sites in the network performed the annual reference dosimetry in water according to TG-51. These data were used to cross-calibrate the same ion chambers in plastic phantoms for monthly QA output measurements. An energy-specific dimensionless beam quality cross-calibration factor, , was derived to monitor the process across multiple sites. The SPC analysis was then performed to obtain the mean, , standard deviation, σk, the Upper Control Limit (UCL) and Lower Control Limit (LCL) in each beam. This process was first applied to 15 years of historical data at the main campus to assess the effectiveness of the process. A two-year prospective study including all 30 linear accelerators spread over the main campus and seven satellites in the network followed. The ranges of the control limits (±3σ) were found to be in the range of 1.7% - 2.6% and 3.3% - 4.2% for the main campus and the satellite sites respectively. The wider range in the satellite sites was attributed to variations in the workflow. Standardization of workflow was also found to be effective in narrowing the control limits. The SPC is effective in identifying variations in the workflow and was shown to be an effective tool in managing large network reference dosimetry.

Student capacity building of dengue prevention and control: A study of an Islamic school, Southern Thailand

Dengue has been a critical problem for an Islamic School, Nakhon Si Thammarat province, Southern Thailand. Objectives: 1) to build student capacity;and 2) to evaluate the results of student capacity building. Method: Participatory Action Research: PAR was applied in three phases: 1) the school-based preparation phase;2) the process of building student capacity phase, and 3) evaluation of the results of the student capacity building. Independent T-Test statistical method was used to analyze student capacity both before and after the intervention. Larval Indices were determined through ratio analysis. Results: Prior to the intervention, there was no clear strategy for combating dengue. In this study, three groups were formed to build student capacity: a leader group, a non-leader group, and a support group. The leader group (48 student leaders), critical to the study, was set as a dengue club named “Eliminate Ades Aegypti, the culprit of dengue” which focused on eight sets of activities: “Dengue or Death”, “Seniors educating juniors”, “Reward for good answers”, “Dengue monitoring team”, “Youth to expel mosquetoes”, “Mosquito or busy”, “Garbage elimination of Pondok”, and “Essential doctors”. The level of student capacity for the prevention and control of dengue of a sampling of 308 student representatives of the Pondok (Islamic school) showed an increase after intervention ( (SD);56.78 (17.06);65.33(15.36) and different statistic significant (P < 0.001). The Larval indices ratio levels had decreased from the original levels (BI = 244, HI = 45, and CI = 26) after intervention (BI = 137, HI = 39, and CI = 19). Dengue morbidity and mortality rates were not found during the study. Discussion: Although there had been an increase in student capacity, a decrease in the larval indices ratio, and the absence of a dengue epidemiology index, the high risk of a dengue epidemic might still be found in the school because the ratio of larval indices were higher than the standard index. Then, the committed participation of students, school, and communities around the school vicinity is needed in building student capacity of dengue prevention and control.

Risk Assessment of Afforestation and Reforestation Processes

Relatively simple forest planting process in real life is not so simple. Its relationships with various environmental, climatic, ecological and other environmental conditions cause a lot of problems. In this paper, hazard analysis critical control point （HACCP） analysis was conducted to identify the critical control points in forest regeneration process. As a result, it has a positive effect on the entire reforestation result. Critical control points will enable timely to draw attention to possible errors or incorrect solutions and consequently improve afforestation or restoration quality. Reforestation often occurs mistakes that lead to an unsuccessful reforestation. To remedy this situation, these critical control points should be identified with HAACP analysis.
