11	Factors affecting the implementation of computer technology in the Imo states high school instructional program Okere, Cleo 01 November 1998 (has links) This study was designed to examine the factors that affect the implementation of computer technology in Imo State, Nigeria, secondary schools' instructional programs. The intent of the study was to determine the relationship between funding, availability of relevant infrastructures, trained personnel, job security, government support and market demand for computer trained personnel and the implementation of computer technology in Imo State school instructional program. A total of three hundred and twelve (312) educators comprising of two hundred and fifty-five (255) teachers, twenty (20) school principals and thirty-seven (37) administrators were randomly selected to respond to questionnaire items about their perceptions of the factors affecting the implementation of computer technology in instructional programs in secondary schools. Twelve research hypotheses were developed to determine the relationships between the factors affecting the implementation of computer technology in the secondary schools' instructional programs. Pearson product moment linear correlation coefficient was used to analyze the data about the relationship between the factors affecting the implementation of computer technology in instructional programs. Also, a one-way analysis of variance (ANOVA) was used to analyze data on the differences in perceptions of the respondents to the questionnaire. The findings showed that school-teachers believed that there were significant relationships between availability of funding, relevant infrastructure, and job security and the implementation of computer technology in secondary schools' instructional programs. Principals and administrators, on the other hand, found no significant relationships between the variables. However, all sampled groups believed that there were significant relationships between job security, government support and market demand for computer trained personnel and the implementation of computer technology in instructional programs in the secondary schools. This study revealed that adequate funding is the key to effective implementation of computer technology in instructional programs in Imo State, Nigeria's secondary schools. This means that, if the Nigerian students from Imo state are to compete effectively in this modem technological age, there is need for the state and national governments to invest more financial resources in the development, production and distribution of technological know-how in the education sector.

12	Modeling of Sulfur Removal from Heavy Fuel Oil Using Ultrasound-Assisted Oxidative Desulfurization Hernandez Ponce, Claudia 07 1900 (has links) Growing environmental concerns, such as global warming, are giving rise to new regulations imposed by the International Maritime Organization (IMO) on sulfur content for marine fuels, thus, constraining refining processes. Oxidative desulfurization (ODS) is an appealing desulfurization method with some advantages over traditional processes like hydrodesulfurization (HDS), such as mild operating conditions and no-hydrogen consumption. ODS could be employed as a complementary or alternative process for HDS. During the oxidative desulfurization, the organo-sulfur compounds are oxidized to polar sulfones. Then, such sulfones are separated from the treated fuel oil using techniques such as liquid-liquid extraction. In the present work, the separation of oxidized sulfur-containing compounds of heavy fuel oil using ultrasound-assisted technology has been investigated and simulated in Aspen Plus. The oxidant selected was hydrogen peroxide, while the catalyst was acetic acid. The chosen solvent for the sulfone separation was acetonitrile. The primary goal of this work is to successfully emulate the operation performed by an oxidative desulfurization pilot plant-scale apparatus designed by Tecnoveritas®, which will later allow the analysis of the parameters on the overall sulfur removal efficiency.

13	Testning av andra generationens stabilitetskriterier enligt IMO Andersson, Jonas, Eriksson, Arvid, Engelfeldt, Kajsa January 2024 (has links) I samband med en växande befolkning och en ökande globalisering beslutadeinternationella sjöfartsorganisationen, IMO, att nya kriterier för stabilitet skulle in-föras. I de nya kriterierna beskrivs ett antal fenomen som kan orsaka haveri, dennarapport fokuserar på ett av dem, parametrisk rullning. Parametrisk rullning är ettfenomen som uppstår då stabiliteten hos ett fartyg varierar periodiskt. Den interna-tionella sjöfartsorganisationen definierar ett antal nivåer bestående av olika modellerför att undersöka risken för att parametrisk rullning ska uppstå och denna rapportbehandlar de första två nivåerna. Rapportens syfte var att bedöma om modellen,definierad av IMO, gick att implementera för att förutspå parametrisk rullning. Föratt modellera den första nivån i MATLAB byggdes ett program för att räkna utden rätande hävarmen som användes för att hitta jämvikter vilket gjordes med deninbyggda funktionen fzero. Samma program som konstruerades för den första ni-vån användes även på den andra nivån. Programmet utökades då den andra nivånevaluerades med en kvasistatisk modell som baserades på en, av IMO definierad, dif-ferentialekvation som löstes med den inbyggda funktionen ODE45. Resultatet frånden första och andra nivån jämfördes med, de av IMO definierade, referensvärdena.Resultaten visade att de två fartygen som tidigare uppvisat tecken på parametriskrullning överskred referensvärdena och de två fartygen som inte bör uppvisa någratecken på parametrisk rullning inte överskred referensvärdena. Slutsatsen blev alltsåatt modellen skapad av IMO korrekt bedömer om ett fartyg kommer kunna drabbasav parametrisk rullning.

15	Effects of Nonadherence to HIV/AIDS Drugs on HIV-Related Comorbidities in Eastern Nigeria Ojukwu, Chizomam Laura 01 January 2019 (has links) Developing countries like Nigeria continue to have HIV epidemic challenge due to the scarcity of evidence-based information and lack of resources to boost HIV education. The study population, Owerri, is one of the states in Nigeria with a high incidence rate of HIV. The purpose of this phenomenological study was to explore the experiences of people living with HIV/AIDS regarding the effects of nonadherence to HIV/AIDS drugs. The integrated theory of health behavior model provided the framework for the study. I collected, transcribed, and analyzed interview data to identify clusters and themes. Results showed that various factors influenced and (e.g., free drugs, fear, culture, medication side effects, discrimination, relationship/support system, poverty, belief, easy access) contributed to adherence behavior among respondents. People living with HIV/AIDS may be encouraged to adhere to drug treatments because of these research findings. This study contributed to a positive social change in that respondents were excited and open about sharing their fears, challenges, struggles and hope with the anticipation to influence others to be open about their HIV disease.

17	Integrated Maritime Simulation Complex Management, Quality And Training Effectiveness From The Perspective Of Modeling And Simulation In The State Of Florida, USA (A Case Study) Sendi, Yaser 01 January 2015 (has links) Naturally, maritime training simulators at all events are valuable instructional and pedagogical tools. Through the history, the maritime simulation was utilized to train prospective maritime apprentices in whom it has filled the gap left by the acute shortage of opportunities for jobs onboard vessels around the globe. However, professional seafarers are the axis of success and competitiveness in the field of maritime training. They are the ones that, who are well trained and have the responsibilities of their work and the surrounding environment. In order to achieve the success along with effective training skills, both maritime companies and seafarers should implement a management of safety onboard ships, which only can be executed through the effective usage of the Bridge Resource Management (BRM) and righteous maritime simulation training. Qualitative upgrading of the maritime training process at higher education levels depends predominantly on the instructive value of the instructors' educational software and the content of these programs which contains advanced and intelligent scenarios that benefit positively in providing effective training in order to, transfer and implement their gained skills from virtual reality to the actual environment with minimal risks and additionally to avoid the unforeseen occurrences at sea. The outcomes of the evaluation have shown the instructional suitability of the maritime educational scheme and significant capabilities, it provides, as well as the domains and frameworks for its instructional development. The above facts are substantial in the refinement and improvement of the current maritime education and growth of the apprentices' capabilities and the professionalism of their skills, along with the farthest purpose of creating more educated marine navigators in the worldwide merchant fleet. This research proposes and demonstrates in details the purpose of the maritime simulation training complexes, the elements that if provided, will lead to an effective maritime simulation training, types of maritime simulation, the International Maritime Organization (IMO), its tools and its power for the effectiveness of the maritime simulation training through different conventions & codes and the future for the maritime simulation training, in order to emphasize and accentuate the interplay between instructors and apprentices in an integrated maritime simulation complex on which a serious maritime event is taking place. The distillation of this thesis draws an attention to the effectiveness of the partnership between maritime apprentices and their instructors across a maritime simulation training complex scheme during a virtual maritime scenario event in an advanced facilities located in the state of Florida, which is armed with modern technology, provides both added stimulation for the apprentice himself and elevates the simulator a degree toward a vessel for practical training and/or sailing.

18	Liquid Natural Gas : A study of the environmental impact of LNG in comparison to diesel / Flytande Naturgas : En studie om LNG:s klimatpåverkan i jämförelse med diesel Edfors, Jonas, Bremberg, Robin January 2021 (has links) Liquefied Natural Gases (LNG) has been an alternative fuel in the marine industry for several years, but lately, the amount of ships that have been powered by methane has increased a lot. Some of the reasons for this is because LNG does not contain any sulfur and releases less nitrogen oxides than traditional maritime fuels. In this essay, LNG will be compared to diesel from an environmental perspective with focus on CO2 emissions and its equivalents. International Maritime Organization (IMO) implemented Energy Efficiency Design Index (EEDI) requirements that adjusts how much CO2 is allowed in the exhaust gas per produced kilowatt-hour (kWh). However, these requirements will increase in intervals in the future, the next one is coming 2022 for specific ship types. The method that is used to compare the fuels is Mole-calculations for LNG as well as diesel, then calculate the amount of carbon dioxide (CO2) and its equivalents they release. The results show that under optimal conditions, LNG was the superior choice. However, the maritime industry might have a problem with the requirements that will be introduced to greenhouse gas (GHG) emissions in 2050. / Flytande Naturgas (LNG) har under flera år funnits som ett alternativt bränsle inom sjöfarten, men på senare tid så har skeppen som drivs av metan ökat markant. En anledning till detta är att LNG innehåller inget svavel samt släpper ut mindre NOX jämfört med traditionella bränslen. I denna uppsats så kommer LNG att jämföras mot diesel ur ett klimatperspektiv med fokus på koldioxidutsläpp och dess ekvivalenter. International Maritime Organisation (IMO) har infört Energy Efficiency Design Index (EEDI) krav som justerar hur mycket CO2 man får släppa ut per kilowattimme (kWh), dessa krav kommer dessutom att öka i flertalet intervaller i framtiden, varav nästa intervall redan sker i 2022 för speciella fartygstyper. Metoden som användes för att jämföra bränslena var att beräkna mol-innehållet för både LNG samt diesel, sen från den beräknade data se hur mycket koldioxid (CO2) inklusive ekvivalenter de släppte ut. Resultatet visade att under optimala förutsättningar så var LNG ett klart bättre alternativ än diesel. Däremot så kan sjöfarten ha ett problem inom framtiden från de krav som berör växthusgaser som kommer att ställas från och med 2050.

19	Barriers to Near-miss Reporting in the Maritime Domain Köhler, Fredrik January 2010 (has links) The catastrophic accident of the ferry Herald of Free Enterprise made it clear that the development of accident prevention in the maritime domain must not only rely on negative events but rather on proactive measures.Near-miss reporting is becoming widespread as a proactive tool for accident prevention in various domains. This thesis aims to examine and identify barriers to near-miss reporting through studying the national reporting system INSJÖ and local company specific systems in the Swedish maritime domain.Interviews with representatives from Swedish shipping companies (designated persons responsible for safety work in each company and officers responsible for the reporting at sea) were conducted as a means of data collection. Based on the data two separate analyses were made; one in a naturalistic fashion and one using a framework of barriers and incentives derived from various social technical domains in which near-miss reporting has been institutionalized.The results of the two analyses highlight differences regarding how and with whom information should be shared. The therapeutic factor, to teach and learn from others was emphasized as important by the majority of the interviewees. Further, potential external influences, issues concerning anonymity and the risk of rehearsed benefits of reporting are also made visible. Finally, critique against the accident-ratio models, that introduced the near-miss concept, is presented and it is argued that these models might be too simplistic to explain why accidents occur.It is concluded that, in order to create effective reporting systems and to decrease the risk of creating a disparity between rehearsed benefits and how the system is used in reality, it is important to give the personnel ownership of their own reporting system and the knowledge of how and why to use it. Nevertheless, near-miss reporting might be used as a powerful tool and incentive for proactive work and accident prevention. near-miss accident incident maritime maritime domain INSJÖ shipping safety accident ratio reporting reporting system IMO master mariner DP Human Computer Interaction
