A Part-Refund Model for Airline Overbooking Problem

In this paper, a mathematical model about the optimal booking level problem in airline overbooking rnanageanent is proposed. Firstly, the normal distribution is employed to approximate Poisson requests and binomial goshows. By calculating the mean loss, a model to describe the relationship between booking level and flight revenue is established. Then, an equation is deduced to decide the optimal booking level. Finally, a numerical example is utilized to illustrate the proposed model and discuss the impact of refund rate on the optimal booking level and the mean loss.

Development of a Comparison Based Hotel and Resort Booking System in Bangladesh

With the rise of population and the industrial revolution, it is obvious that hotels and resorts are increasing drastically day by day. In the 21st century, tourism is a trend. Everyone loves to travel and the reasons vary from person to person. Whether it is to have a cheerful and peaceful mind and place or business purposes, either way, hotels and resorts actually doing their jobs very well. This, tourism is a promising sector for any country and Bangladesh is no different. But the problem is we have to do the hotel booking and reservation manually most of the time. Sometimes it is too troublesome and knowing about the suitable hotels and resorts is too difficult. Though there are some online platforms available, they are not our country-oriented such as the payment system is not preferable for us. To solve this problem Vhromon is developed, a comparison-based hotel and resort booking system where anyone can book a hotel or resort by just login from the internet. Vhromon is an interactive online platform and it is user-friendly and easy to get like most of the platforms available nowadays. But they do not have all the hotels and resorts enlisted, only the well-known ones. On the other hand, Vhromon has everything enlisted where customers can compare them and can choose the right one for them. Furthermore, this system has a vendor panel where any hotel or resort owner can add their hotel or resort easily without any hassle, unlike the existing one.

Asymptomatic Bacteriuria in Pregnant Women in the Antenatal Booking Clinic at Aminu Kano Teaching Hospital, Kano, Nigeria

Asymptomatic bacteriuria is common in pregnant women and if untreated could lead to serious complications. Despite this, its prevalence and microbiological characteristics have not been well studied in Kano and they vary among different populations. The objective of the study was to determine the prevalence, microbiological characteristics and pregnancy outcome of asymptomatic bacteriuria in pregnancy among women who came for antenatal booking clinic at the Aminu Kano Teaching Hospital (AKTH) Kano. A cross sectional descriptive study was conducted among randomly selected 200 consenting pregnant women who came for antenatal booking from November 2010 to January 2011. Samples of 10 - 15 mls urine were examined for pus cells and bacteria and then cultured on cysteine lactose electrolyte deficient agar. Colony counts yielding bacterial growth of 105/ml or more of pure isolates were deemed significant. Isolates were identified to specie level. Antibiotic sensitivity test was done, treatment was given and pregnancy outcome was determined. Urinalysis and Full Blood Count were done. The prevalence of asymptomatic bacteriuria in pregnancy was 9%. Parity and Pyuria had statistically significant association with asymptomatic bacteriuria (P < 0.05). The commonest organisms isolated wereKlebsiella?spp. and?Staphylococcus saprophyticus. Following treatment of asymptomatic bacteriuria, there was no statistically significant difference in pregnancy outcome compared to patients who did not have the condition. The incidence of asymptomatic bacteriuria in pregnancy in AKTH is low. Screening of pregnant women using urine microscopy culture and sensitivity should be reserved for pregnant women with higher risk of developing asymptomatic bacteriuria.

Caesarian Section for Placenta Praevia: Does Booking Status Affect Maternofetal Outcome?

Background: Placenta praevia accounts for significant maternal morbidity and perinatal morbidity and mortality. Despite advances in blood transfusion technique and surgical procedure, abnormal placentation still remains a difficult challenge for obstetricians. Objective: To determine the influence of booking status on the fetal and maternal outcome among parturients with placenta praevia that underwent caesarian delivery. Methodology: This was a comparative and retrospective study between booked and unbooked subjects with significant placenta praevia that were delivered by caesarian section between January 1st 2004 and December 31st 2008 with respect to maternal and fetal outcome. Result: Out of 14,344 deliveries during study period, 123 cases of placenta praevia that underwent caesarian delivery were identified giving a prevalence rate of 0.86%. 49 subjects were booked while 74 were unbooked. There was no statistically significant difference between booked and unbooked cases with respect to risk factors (30.6% of booked and 23% of unbooked), X2(4) = 7.203, P = 0.126 and the mean blood loss at surgery (870.4 ± 486.9 ml in booked versus 779.7 ± 380.96 ml in unbooked), X2(1) = 0.202, P = 0.653. However, antepartum transfusion (12.2% booked versus 34.7% unbooked) and postpartum transfusion (51% booked versus 72% unbooked) showed statistically significant difference, X2(1) = 9.744, P = 0.002. One maternal death occurred amongst the unbooked cases and none among the booked cases. Statistically significant differences were also noted in the apgar score at 1 minute X2(3) = 15.528, P = 0.001 and 5 minutes X2(3) = 12.912, P = 0.005 respectively. More babies died in the unbooked group (19) compared to two (2) in the booked mothers. Conclusion: Unbooked status in placenta previa significantly increases the risk for antepartum and postpartum transfusion, is associated with higher mortality, increased preterm delivery, poorer apgar scores and higher perinatal mortality rate.

Determinants and Outcomes of Pregnancies among Booked versus Unbooked Patients in a Tertiary Hospital South East, Nigeria

Background: Inadequate antenatal care, both in coverage and standard, has been linked with poor pregnancy outcomes. In a resource poor setting, home delivery is considered very cheap, but the possible outcome of such pregnancies has been a subject of interest. This study evaluated the association of booking status with pregnancy outcomes. Objectives: To examine the factors that influence booking and impact of the booking status on pregnancy outcomes. Methods: This was a hospital-based prospective cohort study of 240 (120 booked and 120 un-booked) pregnant mothers selected through systematic random sampling. The study was carried out at the Department of Obstetrics and Gynaecology, Alex Ekwueme Federal University Teaching Hospital Abakaliki, Nigeria. Chi-square test, t-test and logistic regression were used for analysis. Results: The mean age of the participants was 30.39 ± 5.05 years and 29.05 ± 6.36 years respectively for the booked and unbooked. Marital status (OR = 6.35, 95% CI = 1.24 - 32.59), educational status (OR = 36.40, 95% CI = 5.26-152.83), place of residence (OR = 0.15, 95% CI = 0.06 - 0.41), partner’s support (OR = 0.05, 95% CI = 0.01 - 0.37), family support (OR = 0.03, 95% CI = 0.01 - 0.13), mode of delivery (OR = 0.23, 95% CI = 0.12 - 0.46), APGAR score in first minute (OR = 6.02, 95% CI = 2.45 - 14.83) and NBICU admission (OR = 3.75, 95% CI = 1.67 - 8.43) were associated with booked status. However, being unmarried, nulliparity/grandmultiparity, low level of education, blue colar jobs, low income, rural dwelling and poor partner and poor family support were associated with the unbooked. The booked parturients had a better perinatal outcome compared the unbooked. Conclusion/Recommendation: There was high prevalence of operative deliveries, perinatal morbidity and mortality among the unbooked mothers. Girl child education, employment and poverty alleviation would improve antenatal care utilization.

The State of Geological Sciences in the USSR by the Mid-Twentieth Century

Eclampsia: A Continuous Scourge in a Tertiary Hospital in Southern Nigeria

Background: Eclampsia is responsible for over 50,000 maternal deaths with incidence of 1 death in about 100 - 1500 deliveries in developing nations. In sub-Saharan Africa, Nigeria accounts for the highest maternal mortality ratio of 512 deaths per 100,000 live deliveries and the highest neonatal fatality of 67 per 1000 live births. Factors such young age, nulliparity, multifetal gestation, unbooked cases, preterm delivery (<32 weeks), lack of proper access to antenatal care, poor hospital care, financial constraints and inappropriate diagnosis, have all been identified as risk factors promoting eclampsia. Objectives: In this study, we investigated the prevalence of eclampsia in Rivers State, Nigeria and established the correlation between social demographic factors and the feto-maternal outcomes among the eclampsia patients. Methodology: A prospective observational study using a detailed data sheet was conducted on 1244 pregnant women admitted at the Obstetrics and Gynecology Department of University of Port Harcourt Teaching Hospital, for 1-year duration. Data analysis was conducted using statistical packages for social sciences (SPSS) version 22. Results: Demography showed that age range (20 - 24) occurred in 40.7%, nulliparous mothers were dominant with 40.7% while 70.1% of the study population had secondary level of education. 27 cases of eclampsia were diagnosed from the 1244 pregnant women, which signified 2.13% prevalence among the studied population. The feto-maternal outcome showed that out of the 27 mothers, 19 were alive (70.4%) while 8 died (29.6%), while fetal outcome showed that 16 were alive (59.3%) and 11 died (40.7%). Only parity and education showed significant correlation at 0.01 and 0.05 levels respectively with maternal outcome. Conclusion: The prevalence of eclampsia with associated poor feto-maternal outcome rates is high in this study. Its contribution to the maternal and perinatal morbidities and mortalities necessitates the narrative of eclampsia being a scourge, as hypertensive disease remains an obstetric dilemma in both developed and developing countries.

Technological Innovation and Development of the Publishing Industry: The Challenging Digital Transformation of Publishing Houses in Cameroon

In the digital age, performance-oriented publishing houses utilize digital tools to optimize their editorial activities. This optimization affects both editorial practices and products in terms of content and form. These products, now accessible through various media, bring significant changes, while the editorial function undergoes a metamorphosis due to digital exposure. In Cameroon, the book sector is predominantly focused on school textbooks, a legacy from the colonial period. This study investigates the impact of technological innovation on Cameroonian publishing by examining the processes of content selection, legitimization, and dissemination in the digital age. Using the sociology of technology as a framework, we hypothesize an interrelationship between the dominance of textbook publishing and the delayed digital transformation of publishing houses in Cameroon. To explore this hypothesis, we conducted direct observations, interviews with key industry stakeholders, and an extensive analysis of digital adoption metrics within the publishing sector. Our research reveals that the historical focus on educational publishing has created structural and cultural barriers to embracing digital innovations. Moreover, limited infrastructure and a lack of digital literacy among publishing professionals further hinder the transition. Despite these challenges, there are emerging opportunities for digital transformation, particularly in diversifying content and expanding access through digital platforms. Our findings indicate that a strategic shift towards embracing digital tools and improving infrastructure could significantly enhance the efficiency and reach of Cameroonian publishing houses. By addressing the specific challenges identified in our study, the industry can leverage digital technologies to foster a more inclusive, dynamic, and resilient publishing environment. This study provides a detailed examination of the specificities of digital transformation in Cameroonian publishing, offering insights for policymakers and industry stakeholders aiming to promote technological innovation in the sector.
