Nomel Paul Stéphane Essoh
American Journal of Industrial and Business Management (AJIBM) , 2013, DOI: 10.4236/ajibm.2013.33042
Abstract:

This research paper aims to study the correlation between the port activity and the activity of the different services sectors. By comparing trends between them and analyzing the causality relationships between the port traffic and the other economic sectors, our study tends to present how the activity of the port of Abidjan could have a decisive effect on the local economy. To meet our objectives, correlation analysis and statistical test tools Eviews and other techniques have been run with data provided by local agencies and port authority. By doing so, our research study finds that there is existing correlation between port activity and activity generated by the other services sectors and its contribution can accelerate the economic growth.

Climate and Epidemiology of Malaria in Port Harcourt Region, Nigeria  [PDF]
Vincent Ezikornwor Weli, Sunday Ighovie Efe
American Journal of Climate Change (AJCC) , 2015, DOI: 10.4236/ajcc.2015.41004
Abstract: The study examines the effect of climate on the occurrence of malaria in Port Harcourt. To achieve this, the study adopted the survey designs which involved the use of archival data of climate parameters and the survey of hospitals for epidemiological data of malaria cases reports within Port Harcourt and environs. The archival weather data on temperature and rainfall were collected from the Nigeria Meteorological Service Agency (NIMET) for a period of sixty-five (65) years (1950-2014), and those for medical records of malaria cases were extracted from the University of Port Harcourt Teaching Hospitals (UPTH), Braithwaite Memorial Hospital (BMH) and some renowned private hospitals in Port Harcourt and environs for a period of sixty-five (65) years. The multiple regression analysis was used to determine the relative effect of rainfall and temperature on malaria incidence. The polynomial and linear trend analysis was used for the trend pattern of malaria cases, rainfall and temperature. The results revealed an annual rainfall of 2375 mm, with an increase of 1581 mm of rainfall from 1950 till date. It also showed an urban warming of 3°C from 1950 to 2014, and a mean of 27.2°C in temperature in Port Harcourt. The results of the multiple regression reveal that the prevalence of malaria is significantly dependent on the increase in rainfall and temperature in Port Harcourt. There are double maxima of malaria cases with 1006 cases in July and 1540 cases in September, which coincide with the months with double rain maxima. On this premise and health care planning and development, it is recommended that regular clearing of drains and the surrounding environment on monthly basis should be intensified, as well as the distribution of mosquito’s insecticide net by the three tier of government.

T. K. Nyengidiki, E. O. Oranu
Journal of Biosciences and Medicines (JBM) , 2018, DOI: 10.4236/jbm.2018.66005
Abstract: Background: The high risk human papilloma virus (hrHPV) is largely associated with cervical cancer with identifiable dysplastic changes on cytology. The use of cervical cancer screening strategies has largely improved the general outcome of cervical malignancies globally. Objective: To compare cervical cytological features against human papilloma virus genotypes in non HIV positive patients presenting for cervical cancer screening in UPTH. Method: A cross sectional prospective study of 82 non HIV positive women who presented for cervical cancer screening at the University of Port Harcourt Teaching hospital. A prestructured questionnaire was used to obtain socio demographic information. Cytobrush extracts of cervical samples were subjected to cytology and human papilloma virus DNA genotyping using real-time polymerase chain reaction. The information obtained was analyzed using SSPP version 20 and results presented as frequency tables, percentages and tested for significance using student t-test and chi square with p value < 0.05 at 95% confidence interval. Results: The mean age of the women was 36.61 ± 7.75 with an age range of 22 - 58 years. The prevalence of HrHPV was 4.88%. Twenty-two of the respondent have abnormal cytological pattern. While the 4 cases of HrHPV positivity were of normal cytological pattern and occurred in respondents that were in their reproductive age, the 22 that showed abnormal cervical cytology were mainly of low grade squamous intraepithelial lesion (LGSIL). There was no case of high grade squamous cell intraepithelial lesion (HGSIL). Conclusion: HrHPV prevalence rate of 4.88% occurring in low socioeconomic class patients. All the cervical abnormalies were of LGSIL, hence the risk of transformation into cervical cancer is equally low. There may be no correlation between hrHPV and cervical cytology in low risk patients.

A Personnel Detection Algorithm for an Intermodal Maritime Application of ITS Technology for Security at Port Facilities  [PDF]
Mouhammad K. Al Akkoumi, Robert C. Huck, James J. Sluss
Journal of Transportation Technologies (JTTs) , 2011, DOI: 10.4236/jtts.2011.14016
Abstract: With an overwhelming number of containers entering the United States on a daily basis, ports of entry are causing major concerns for homeland security. The disruption to commerce to inspect all containers would be prohibitive. Currently, fences and port security patrols protect these container storage yards. To improve security system performance, the authors propose a low cost fully distributed Intelligent Transportation System based implementation. Based on prior work accomplished in the design and fielding of a similar system in the United States, current technologies can be assembled, mixed and matched, and scaled to provide a comprehensive security system. We also propose the incorporation of a human detection algorithm to enhance standard security measures. The human detector is based on the histogram of oriented gradients detec- tion approach and the Haar-like feature detection approach. According to the conducted experimental results, merging the two detectors, results in a human detector with a high detection rate and lower false posi- tive rate. This system allows authorized operators on any console to control any device within the facility and monitor restricted areas at any given time.

Abstract:

Backgound: Laparoscopic cholecystectomy has revolutionized the world in the surgical management of benign gallbladder disease. However, for any procedure to learn properly, anatomy becomes a major concern. Aims and Objectives: We present a point, a convenient site, speedily accessible by our maneuver of placing epigastric port on the patient. Materials and Methods: This is an outcome of an observation with the prospective study of 100 patients irrespective of age, sex, body habitus and severity of gallstone disease. Our point for epigastric port satisfies all the criteria for an ideal port. Results: Our general observation with majority of patients with this point specific epigastric port placement was that it is easy to locate, needs less thrust on trocar for creation, stays on the linea alba, is easily maneuverable facilitates safe, easy and speedy dissection, causes less portal bleeds and is easy to angulate towards the right of falciform ligament. Conclusion: The point specific epigastric port conveys many benefits to the operating surgeon in terms of easy location, adds safety and speed to the procedure, causes less portal bleeds, needs less thrust and is easy to angulate to the right of the falciform ligament adding technical ease to the surgeon. It is easy to be learnt, taught and practiced by the young surgeons.

Surgical Science (SS) , 2013, DOI: 10.4236/ss.2013.410085
Abstract:

Background: The use of single-port laparoscopy has gained popularity within recent years. Part of the appeal in learning this approach is that it draws heavily from concepts mastered through conventional laparoscopy. Various studies have shown the efficacy and feasibility of the single-port laparoscopic approach, but there are few that examine the learning curve in adopting this new technique. Objective: Our goal was to better define the learning curve in performing a single-port laparoscopic right hemicolectomy. Design: A review of prospectively gathered operative data was performed to analyze the results of single-port laparoscopic right hemicolectomies performed within our institution by experienced laparoscopic surgeons. The first 100 cases were divided into quintiles. Comparisons were made among the cohorts regarding patient demographics, operative time, length of stay, conversions, and complications. Results: There was no difference among quintiles with regard to age, sex, BMI, or ASA class. Operative time, conversions, length of stay, and number of complications did not significantly vary among each group of patients. There was a significant difference in estimated blood loss and length of stay between the fifth cohort and the others due to one patient’s poor outcome. Conclusions: The single-port laparoscopic right hemicolectomy learning curve for surgeons already skilled in laparoscopy is short. There are few differences in various outcome measures among groups at any stage in the learning curve. The skills utilized to perform conventional laparoscopic colorectal surgery readily translate to the single-port approach and result in proficiency from nearly the start.

Natural Resources (NR) , 2015, DOI: 10.4236/nr.2015.61001
Abstract: Floods are naturally occurring phenomena that are part of the physical and biological process which have shaped our nation’s landscape. It occurs in Nigeria environment when there is heavy rain fall for prolonged period of time. The data collection for this research was by use of primary and secondary information; questionnaire was administered by face to face interviews and key informant surveys. Analytical technique was the univariate statistical methods. The results revealed that there is clear evidence of damages to properties and that there are hazards and risks faced by these households as shown in Tables 1-4 respectively. Table 3 specifically shows the financial losses incurred annually by residents to the tune 5 million naira and above. However, the continued hazards and risks as a result of flood incidence have affected their overall income which hitherto is found within (N20000.00 - N25000.00) about 22.8% of the respondents fall in this income bracket. Furthermore, the research also revealed that about 30% say the flood has affected their income, while 29.4% say their buildings are affected. Also about 37.8% of respondents say that the flood incidence occurs all through the rainy season. The research recommends an aggressive review of the Port Harcourt Master Plan and the implementation of the development control tools in the 1992 Urban and Regional Planning Law.

Abstract: Dermatophytoses are the most common dermatological conditions but they are however not life threatening or debilitating hence medical care is sought usually due to aesthetic reasons and chronicity of the lesions despite several self-medications. The purpose of this study was to determine the distribution pattern of dermatophytes isolated in the medical microbiology laboratory of University of Port Harcourt teaching hospital (UPTH). This is a 5-year desk review of the Dermatophytes isolated in the medical microbiology laboratory of UPTH. Relevant Patients’ data were retrieved and analyzed. A total of seventy (70) dermatophytes were isolated over the five-year period as follows: Trichophyton species accounted for 55 (79%), Epidermophyton species were 8 (11%) and Microsporum species 7 (10%). The peak age range of patients from which dermatophytes were isolated was 31 - 40 years with a male to female ratio of 1:1.7. The majority of patients being 49 (70%) were referred from the dermatology outpatient clinic (DOPC) and the most frequent clinical diagnosis was Tinea corporis. Trichophyton species were the commonest cause of dermatophytoses in adult patients in Port Harcourt where the most common clinical presentation was Tinea corporis.
