Effects of maritime logistics on port efficiency in Nigeria
(Federal University of Technology, Owerri, 2024-03) Nnaukwu, Charles
The study analyzed the effects of maritime logistics on port efficiency in Nigeria. It used the Lagos Apapa port and Eastern port of Onne to investigate the effects of maritime logistics performance on port efficiency in Nigeria. The ex-post facto research design was used in which secondary data on the ship turnaround time, waiting time, time at berth and cargo dwell time prevailing in Lagos Apapa port and Onne port each year between 2007 and 2019 was obtained and used as proxies for maritime logistics performance and the cargo throughput performance and ship call handled by the port was used as indicators of productivity. The time expended per annum in port operations measured in man-hours and the average time vessels spent at berth annually in the ports between 2007 and 2019 were obtained and used as input to estimate the efficiency of the port in cargo handling relative to expended efforts in man-hours, the efficiency of the port in handling ship calls and the berth efficiency of the port. The augmented efficiency model was used to estimate the efficiency of the port as described above while the log-linear multiple regression analysis was used to estimate the effects of maritime logistics performance on the cargo handling efficiency, ship output efficiency and berth efficiency of the seaport. The test of hypotheses reveals that in all cases, there is a significant effect of maritime logistics performance on each of cargo handling/throughput efficiency, ship output efficiency and berth efficiency in both ports. The models showing the relationships and effects of maritime logistics on the various components of port efficiency in Onne are shown: In EFFICARPUT = 1.366 - 0.072InSHTRTIME + 0.081InCARGODWELLTIME + 0.014InWAITINGTIME -0.16InBERTHTIME + e; In EFFISHTR = 0.007+ 0.109InSHTRTIME - 0.001InCARGODWELLTIME + 0.001InWAITINGTIME + 0.003InBERTHTIME + e; and In BERTHEFFICIENCY = 1.103+ 1.667InSHTRTIME + 0.193InCARGODWELLTIME + 0.264InWAITINGTIME - 5.706InBERTHTIME + e. For Lagos Apapa port, In BERTHEFFICIENCY = 23.320 + 0.252InSHTRTIME + 0.072InCARGODWELLTIME - 0.041InWAITINGTIME - 8.535InBERTHTIME + e; In EFFISHTR = 0.698+ 0.27InSHTRTIME + 0.031InCARGODWELLTIME -0.004InWAITINGTIME - 0.025InBERTHTIME + e. It was recommended among other things that, port authorities and terminal operators must implement maritime logistics strategies to improve the maritime logistics performance indicators and subsequently improve port efficiency.

Utilization of family planning services among women of childbearing age in Owerri Municipal LGA
(Federal University of Technology, Owerri, 2022-02) Nlemadim, Vivian Chiamaka
This study investigates the utilization of family planning services among women of childbearing age (15-49) in Owerri Municipal, Imo State, Nigeria. Sociocultural factors significantly influence family planning decisions, highlighting the need for culturally sensitive approaches. To determine the factors affecting the utilization of family planning services among women of childbearing age in Owerri Municipal LGA. A cross-sectional study was conducted with 398 women of childbearing age in Owerri Municipal LGA, selected using simple random sampling techniques. Data were collected through a self-structured questionnaire and analysed using SPSS version 25. Frequency and percentages of relevant variables were calculated, and Chi-square tests and odds ratios were employed to assess significant associations, with a p-value ≤ 0.05 considered significant. Of the 397 respondents, 54% reported having heard of family planning, while 46% had not, with no significant association found between knowledge and utilization (p = 0.081). Cultural factors (37.5%) and religious affiliation (30.4%) significantly influenced family planning decisions. Notably, 48.1% faced opposition to family planning, indicating an association between sociocultural factors and service utilization (p = 0.013). Partner support (34.0%) and participation (35.9%) were identified as critical for successful family planning, and 34.0% of health workers received regular training updates. The study underscores the importance of enhancing knowledge of family planning among women and making services more accessible and affordable. Continuous training for healthcare providers is essential to improve the quality of care and support for family planning initiatives.
Epidemiology of extended spectrum beta lactamase (ESBL) producing enterobacteriaceae isolated from selected hospitals within Owerri metropolis in Imo State
(Federal University of Technology, Owerri, 2023-11) Moses, Abasiodiong
Over the past few decades, resistance to antibiotics has been of great concern to the general public, hence the several researches and measures to control it. Extended spectrum β-lactamases (ESBLs) are enzymes produced by plasmids possessed by enterobacteriaceae, capable of hydrolyzing broad spectrum cephalosporins and monobactam but inactive against cephamycins and imipenem compounds. Hence, the aim of this study was to determine the epidemiology of ESBL producing enterobacteriaceae from clinical samples within selected hospitals in Owerri metropolis by determining the resistant bacterial urine and stool, the antibiotic susceptibility pattern and phenotypically determining the ESBL producing isolates using the Double Disc Synergy Test (DDST) method as well as confirming the genes responsible for the resistance using the Polymerase Chain Reaction (PCR). Out of 300 analyzed urine and stool, 165 (55%) yielded bacterial growth; of which 107 (64.8%) was identified as Escherichia coli (E. coli) and 58 (35.2%) was identified as Klebsiella pneumoniae (K. pneumoniae).The overall resistance rate of the isolates to antibiotics include: Imipenem (50) 30.3%, Ceftazidime (128) 77.6%, Cefotaxime (118) 71.5%, Augmentin (72) 43.6%, Cefepime (133) 80.6%, Trimethoprim (63) 63%, Chloramphenecol (55) 55%, Septrin (65) 65%, Ciprofloxacin (54) 54%, Amoxicilin (65) 65%, Augmentin 2 (42) 42%, Gentamicin (44) 44%, Pefloxacin (49) 49%, Ofloxacin (60) 60% and Streptomicin (56) 56%. A total of 72 bacterial isolates (43.6%) were identified as ESBL producing, comprising 47 (65.3%) E. coli and 25
(34.7%) K. pneumoniae. Three (3) ESBL genes TEM, SHV and CTX-M were detected on seventeen (17) random isolates, with a prevalence rate of 5 (29.4%) for TEM/SHV, 9 (52.9%) for TEM/CTX, 4 (23.5%) for SHV/CTX, 4 (23.5%) for the three (3) genes and 2 (11.8%) did not possess any of the genes. Several factors have been traced to be a contributing factor to antibiotic resistance such as drug abuse, poor diagnosis, poor treatment of ailments, poverty, intake of fake and expired drugs, among others hence the need for need for public awareness on the dangers associated with abuse and intake of fake or expired of antibiotics. Most importantly the governments’ provision of primary health care centers where patients can have easier access to health care workers is encouraged. The study underlined the high prevalence of antibiotic resistance among humans, hence the need to adopt quicker and more effective measures to combat them.
