Effects of Dropsonde Data in Field Campaigns on Forecasts of Tropical Cyclones over the Western North Pacific in 2020 and the Role of CNOP Sensitivity

Valuable dropsonde data were obtained from multiple field campaigns targeting tropical cyclones,namely Higos,Nangka,Saudel,and Atsani,over the western North Pacific by the Hong Kong Observatory and Taiwan Central Weather Bureau in 2020.The conditional nonlinear optimal perturbation(CNOP)method has been utilized in real-time to identify the sensitive regions for targeting observations adhering to the procedure of real-time field campaigns for the first time.The observing system experiments were conducted to evaluate the effect of dropsonde data and CNOP sensitivity on TC forecasts in terms of track and intensity,using the Weather Research and Forecasting model.It is shown that the impact of assimilating all dropsonde data on both track and intensity forecasts is case-dependent.However,assimilation using only the dropsonde data inside the sensitive regions displays unanimously positive effects on both the track and intensity forecast,either of which obtains comparable benefits to or greatly reduces deterioration of the skill when assimilating all dropsonde data.Therefore,these results encourage us to further carry out targeting observations for the forecast of tropical cyclones according to CNOP sensitivity.

The Impact of Community-Based Awareness Campaigns on the Early Breast Examination among Women at King Faisal University

Background and Objective: Breast cancer (BC) is the most common cancer between females in Saudi Arabia, the eastern area ranked as the first in the incidence rate. As the breast cancer awareness movement has expanded, majority of the new cases are still diagnosed in a later stage. This study aimed to evaluate the impact of breast cancer awareness campaigns on the knowledge and practice of early breast examination (EBE) which consisted of breast-self examination (BSE), clinical breast examination (CBE) and mammography, among women at King Faisal University. Methodology: A cross-sectional study carried out at King Faisal University, Al-Hassa city on a sample of 300 adult females from different urban and rural areas. A pre-tested, self-administered questionnaire was distributed to the participants. The questionnaire contains questions about: socio-demographic factors, awareness campaigns, practice and knowledge of breast cancer and early screening methods. Results: The age of the participants ranged from 16 to 60 years;53% of the participants have attended campaigns;and 47% have never attended. Regarding the practice of BSE, CBE and mammography, the results were 8.8%, 3.3%, and 4.3%, respectively. The results show a significant relation between attending campaigns and good level of practice and knowledge. Conclusion and Recommendation: The findings indicate a great impact of the community-based awareness campaigns on the practice of EBE. The study recommends a multilevel intervention for every age group, specially the age group that at risk.

Public Health Campaigns and Medicine Use Awareness: A Systematic Literature Review

This study investigates the medicine awareness, which can be defined as the increase in knowledge and understanding of the general public on appropriate medicine use. Objective: To identify the characteristics of Public Health campaigns that focus on medicine use and/or medicine awareness. Study Design: Systematic review focusing on pre- and post-campaign surveys. Methods: Electronic databases: PubMed, Science Direct, Web of Knowledge, Scopus, Global Health, and Google Scholar were searched. Articles within the last 10 years, with a focus on adults over the age of 18 were used to report findings. Results: A total of 4336 studies were reviewed after which eight were identified, which focused on medicines use and/or awareness. Most campaigns emphasized the knowledge and understanding of patients on the importance of appropriate medicine use and drew a comparison from pre- to post-campaign results. A limited number of Public Health campaigns demonstrated an increase in the level of medicines use awareness of patients. Various tools were used to portray the message across in the campaigns. These included, video, written information, face to face approaches, as well as educational games. Four studies demonstrated a statistically significant increase, in awareness of the public in regards to medication. However, the remaining studies were not successful in portraying a significant impact. Conclusion: Most campaigns demonstrated a limited increase in level of medicine use awareness in their post-campaign surveys. The results support the need for a comprehensive Public Health campaign that focuses on medicine use.

Mammography during Breast Cancer Awareness Month Campaigns in Lomé(Togo): In Relation to 1074 Cases over a Period of 5 Years

Background: This study aimed to describe the results of mammography done during breast cancer awareness campaigns in Lomé. Methods: This was a retrospective multicenter study which focused on the analysis of mammographic examinations, with or without breast ultrasound, carried out in three (3) clinics in Lomé over a period of five (5) years during the breast cancer awareness month (Pink October) campaigns. We included in our study women of all ages who underwent a mammography during the study period. Additional ultrasound was performed as needed in some women to better characterize a lesion. The parameters studied were socio-demographic data, and aspects of breast lesions. We classified the lesions in order of severity according to the BI-RADS classification. Results: During the study we counted one thousand and seventy-four (1074) women who underwent mammography examinations, corresponding to an average of 214.8 women per year. The median age of the women was 46 years. The most represented age group was 40 - 49, constituting 30% of cases. Mammography was performed on all women and ultrasound was performed on 51.3% of women. Lesions suspicious for malignancy (BI-RADS IV) and lesions highly suggestive of malignancy (BI-RADS V) represented 3.5% and 1.9% of cases respectively, amounting to a prevalence of 5.4%. They occurred more frequently from the age of 30 years with a statistically significant difference (p = 0.02). These lesions could be identified on mammograms as masses with irregular shapes and spiculated margins representing 16.1% and 9.7% of masses respectively. On ultrasound, these were solid masses with irregular and ill-defined borders, representing 25.2% and 5.2% of solid masses respectively. Lesions suspicious for malignancy were most often found in the UOQ (upper outer quadrant) in 70% of cases. Conclusion: Mammography screening for breast cancer remains a necessity in our community, even if the rate of cancer detected remains low. It allows for early diagnosis of cancers, promoting better management.

Do anti-corruption campaigns affect IPO underpricing?Evidence from a central discipline inspection of the CSRC in China

The system of central discipline inspections has become a key anti-corruption governance tool in China since 2013.This paper investigates the impact of a central discipline inspection of the China Securities Regulatory Commission(CSRC)on initial public offering(IPO)underpricing.We find that IPO firms listed during the inspection period exhibit greater IPO underpricing than those listed outside the inspection period.The reason is the increased focus of the CSRC on maintaining capital market stability,which makes it more inclined to approve IPO firms with lower issue prices during the inspection period compared with other periods.We also find that IPO firms listed during the inspection period have better short-term market performance but poorer long-term returns than those listed outside the inspection period.Moreover,the effect of the anti-corruption inspection on IPO underpricing is more pronounced for non-state-owned enterprises,firms with low-quality auditors and firms located in regions with high corruption.Overall,our paper enriches the literature on IPO underpricing and the economic consequences of the central discipline inspection system.

Public Risk Perception Attitude and Information-Seeking Efficacy on Floods:A Formative Study for Disaster Preparation Campaigns and Policies

Floods are among the most frequent and devastating natural hazards and disasters in many southern states in the United States.This study examined the relationship and reciprocal predictability between two theoretical constructs-risk perception attitude(RPA)and informationseeking efficacy(ISE)——in regard to pluvial floods.In addition,this study extended these theoretical constructs to investigate differences in RPA and ISE among potential audience segments,providing practitioners with applicable insights for designing effective flood prevention and risk management campaigns.Analysis of data from 716 residents in south Louisiana revealed a statistically strong relationship between RPA and ISE.This research also identified specific audience segments that would benefit from an increase in RPA and ISE concerning floods.These meaningful findings infonn a discussion of the theoretical and practical implications of the relationship between RPA and ISE and guide future disaster preparation campaigns and policies.

A Seismic Facies Analysis to Determine the Relative Age and History of the Al Idrissi Mud Volcano from Offshore Larache Located in the NW Moroccan Atlantic Margin

Formed on top of the Gulf of Cadiz, the Al Idrissi mud volcano is the shallowest and largest mud volcano in the El Arraiche mud volcano field of the northwestern Moroccan margin. The development and morphology of mud volcanoes from the El Arraiche mud volcanoes group have been studied at a large scale. However, the time interval related to their formation period still needs to be better understood. In this regard, we interpreted and analyzed the seismic facies from the 2D reflection data of the GEOMARGEN-1 campaign, which took place in 2011. The aim was to identify the seismic sequences and draw the Al Idrissi mud volcano system to determine the formation period of the Al Idriss mud volcano. And as a result, the Al Idrissi mud volcano system is made of both buried and superficial bicone and was identified along with the Upper Tortonian to Messinian-Upper Pliocene facies. As the initial mud volcano extrusive edifice, the buried bicone was formed in the Late-Messinian to Early-Pliocene period. However, the superficial bicone, as the final extrusive edifice, was included in the Late Pliocene. In this case, the timing interval between the buried and superficial bicone is equivalent to the Late-Messinian to Upper-Pliocene period. Therefore, the latter corresponds to the Al Idrissi mud volcano formation period.

Contributions of the Measles Follow-Up Vaccination Campaign to Improving the Vaccination Coverage of Children Aged 6 - 59 Months in the Democratic Republic of the Congo in 2019

Background: In accordance with its measles elimination strategic plan 2012-2020, the Democratic Republic of the Congo (DRC) organized a follow-up vaccination campaign against measles from October to December 2019 in 26 provinces. This study aims to establish the contribution of this supplementary vaccination campaign to protecting children against measles. Methods: The survey was carried out in November 2020 among households of the DRC, according to the 2018 revised version of the World Health Organization’s stratified cluster sampling method, using multiple stage sampling. It targeted 280 children aged 6 - 59 months per stratum or province, with 10 children in each of the 28 selected clusters. Data collection using tablets with centralized and real-time data processing was preceded by enumeration to refine the household sampling frame. Clusters and households were selected by random draw. Data collected with CS Pro 7 software were analyzed with SPSS, Epi info 7 and Excel software to determine indicators and make before-after comparisons using the McNemar test, at a precision threshold of 5%. Results: Of the 8535 surveyed children, 89.5% were vaccinatedduring the follow-up campaign and 81.6% were vaccinated before. Only 3.7% had correctly completed campaign vaccination cards. Estimated vaccination coverage increased from 80.8% before the campaign to 92.6% after the campaign (p 0.001). Vaccination coverage after campaign against measles improved in all provinces (p < 0.001) except Bas-Uele and Maniema. Thirteen provinces reached the national coverage target of 95%, compared to five before the campaign. The proportion of zero-dose children dropped significantly after this campaign from 19.2% to 7.4% (p 0.001), and even fell below 1% in six provinces. Conclusion: This measles vaccination campaign improved overall vaccination coverage by 10% and reached more unvaccinated children. Efforts must continue to improve the retention of vaccination card, the adherence of unvaccinated children and the effectiveness of routine vaccination.

Planning the hepatitis C virus elimination in Cyprus:A modeling study

BACKGROUND Hepatitis C virus(HCV)infection is a major global public health problem.In the Republic of Cyprus,the estimated prevalence of chronic hepatitis C(CHC)among the general population is 0.6%,while the CHC prevalence among people who inject drugs(PWID)is estimated at 46%.Direct-acting antivirals that can eliminate HCV are not yet widely available in the Republic of Cyprus.However,when direct-acting antivirals become available,a long-term strategic plan to guide elimination efforts will be needed to maximize the effect of treatment.AIM To determine the programmatic targets to eliminate HCV in the Republic of Cyprus.METHODS A dynamic,stochastic,individual-based model of HCV transmission,disease progression,and cascade of care was calibrated to data from Cyprus.The model stratifies the population into the infected general population and the PWID population.A variety of test,prevention,and treatment strategies concerning the general population,PWID,or both were examined.The time horizon of the analysis was until 2034.RESULTS Under the status quo scenario,the model predicted that 75(95%confidence interval(CI):60,91)and 575(95%CI:535,615)liver-related deaths and new infections would occur by 2034,respectively.Launching an expanded treatment program,without screening interventions,would cause modest outcomes regarding CHC prevalence(16.6%reduction in 2034 compared to 2020)and liverrelated deaths(10 deaths would be prevented compared to the status quo scenario by 2034).Implementing a test and treat strategy among the general population but without any intervention in the PWID population would suffice to meet the mortality target but not the incidence target.To achieve HCV elimination in Cyprus,3080(95%CI:3000,3200)HCV patients need to be diagnosed and treated by 2034(2680 from the general population and 400 from PWID),and harm reduction coverage among PWID should be increased by 3%per year(from 25%in 2020 to 67%in 2034).CONCLUSION Elimination of HCV is a demanding public health strategy,which requires significant interventions both among the general population and high-risk groups.

The research is a quantitative design based on a survey of students (N = 700) at the University of Tabuk in the Saudi province of Tabuk. The findings were that the students’ knowledge of diabetes indicators was encouraging, and that the faculty’s periodic diabetes awareness programs should be continued to ensure that new students can recognise diabetes characteristics. In assessing variables for knowledge of the disease in relation to the demographics of people on the Tabuk University campus, marital status and weight were significant indicators. The conclusion was that awareness programs should be continued to avoid complacency and to combat the disease.

Mass Distribution Campaign of Long-Lasting Insecticidal Nets in the Democratic Republic of Congo from 2018 to 2021 in the Context of the Emergence of COVID-19: Results and Lessons Learned

Introduction: The DRC had planned 23 mass distribution campaigns distribution of long-lasting insecticidal nets (LLIN) for the years 2018-2020, the implementation of which spanned from 2018 to July 2021. This article reviews the campaign’s planning process, the results, challenges, and lessons learned. Methods: A descriptive method was used to postpone the planning and implementation process according to the National Malaria Control Program (NMCP) standards adapted to the COVID-19 context. The changes and adaptations implemented as well as the challenges encountered are described. Results: Between January 2018 to June 2021, 23 LLIN mass distribution campaigns were organized in the DRC with the financial support of The Global Fund to Fight against Tuberculosis, AIDS and Malaria (GFTAM) and Against Malaria Foundation (AMF) allowing the distribution of 55,273,473 LLINs to 19,048,372 households at risk of malaria transmission with an average of 2.9 LLINs per household. The enumerated population (111,081,191) exceeded 7% of the micro plans projected population (102,790,391) while the number of households enumerated (19,311,629) was 3% lower compared to the micro planning projection households (19,862,417). Compared to a reported household coverage of 96% of households achieved over the expected households, the independent monitoring carried out revealed 91% of households served in the intervention areas. The main reasons for not reaching households mentioned by the respondents were absence at the time of distribution (26%) followed by the loss of vouchers (16%). Several communication channels were used among which, community workers were the most frequently mentioned (63.1%), followed by radios (18.5%) and churches (12.4%). Conclusion: Good planning, effective coordination of stakeholders, and revision of the implementing campaigns methods following the COVID-19 were factors in the success of this campaign. An effort to respect the schedules for renewing LLINs in households, coupled with good continuous distribution, is necessary to maintain the gains and hope for an impact in terms of morbidity and mortality reduction of malaria.

Monitoring Method for Blast Furnace Wall With Copper Staves

A monitoring method that has been designed for the first time for blast furnace wall with copper staves manufactured in China was introduced. Combining the method of ＂inverse problem＂ and the concept ＂non-inverse problem＂, the monitoring program for blast furnace wall with copper staves has been realized, which can be used to calculate online the accretion thickness and temperature of hot surface of copper staves after obtaining the values of thermocouples of copper staves. The accretion state obtained in the actual investigation has proved that the result of the program is correct. The monitoring program shows that the accretion would easily fluctuate when the accretion layer is extremely thick or thin, thereby the stable and smooth operation of the blast furnace is hindered. By maintaining appropriate accretion thickness, both long campaigns and high productivity of the blast furnace can be achieved; furthermore, it can also optimize the operation of blast furnace and maximize its production. Approximately 30--50 mm in thickness of accretion layer is maintained on the wall of Shougang blast furnace 2, which can meet the requirement for obtaining both long campaign and high productivity.

Practice for Extending Blast Furnace Campaign Life at Wuhan Iron and Steel Corporation

One of the problems encountered in 60＇s to 80＇s of 20th century in China＇s steel industry was short life of blast furnace shaft as well as the excessive erosion of blast furnace hearth. A series of research work was carried out in order to extend blast furnace campaign life. The concept of research and development was integrated in the construction of BF （blast furnace） No. 5 at WISCO （Wuhan Iron and Steel Corporation）, and in October, 1991, the BF No. 5 was blown in. The blast furnace has worked smoothly for more than 15 years without any medium repair even guniting. It is expected that the campaign life of BF No. 5 would be longer than 16 years with a production over 11 000 t per unit inner volume （m^2）. A new blast furnace with an inner volume of 3 400 m^3 is under construction, and is designed with a campaign life of 20 years without any medium repair. The campaign life of blast furnaces in China has been extended in recent years.

A Closure Study of Aerosol Hygroscopic Growth Factor during the 2006 Pearl River Delta Campaign

Measurements of aerosol physical, chemical and optical parameters were carried out in Guangzhou, China from 1 July to 31 July 2006 during the Pearl River Delta Campaign. The dry aerosol scattering coefficient was measured using an integrating nephelometer and the aerosol scattering coefficient for wet conditions was determined by subtracting the sum of the aerosol absorption coefficient, gas scattering coefficient and gas absorption coefficient from the atmospheric extinction coefficient. Following this, the aerosol hygroscopic growth factor, f（RH）, was calculated as the ratio of wet and dry aerosol scattering coefficients. Measurements of size-resolved chemical composition, relative humidity （RH）, and published functional relationships between particle chemical composition and water uptake were likewise used to find the aerosol scattering coe？cients in wet and dry conditions using Mie theory for internally- or externally-mixed particle species [（NH_4）_2SO_4, NH_4NO_3, NaCl, POM, EC and residue]. Closure was obtained by comparing the measured f（RH） values from the nephelometer and other in situ optical instruments with those computed from chemical composition and thermodynamics. Results show that the model can represent the observed f（RH） and is appropriate for use as a component in other higher-order models.
