DESIGN AND IMPLEMENTATION OF A COMPUTERIZED CRIME MANAGEMENT SYSTEM
CASTE STUDY: NIGERIAN POLICE FORCE CENTRAL POLICE STATION ENUGU.

ABSTRACT
Computerized crime management systems have been one of the most widely deployed management science technologies in the fight against crime. Computers are now in irremovable part of the arsenal of the fight against crime.
In this project work, based on the crime wave in our society today, it is very necessary to propose a computer based approach or search systems to facilitate the activities of the police who are interested in combating criminal cases especially crime.
It is suggested that the user interface problems is nearly insurmountable for local police agencies but that effective use of the computerized crime management system might be substituted for inadequate user interface design. Recommendations are provided to address the problems encountered.

1.0 INTRODUCTION
The present, in his yearly state of he union message to congress announced a ground plan: “To bring the most advanced technology to the war on crime in every city and country in Nigeria”. In less than ten months congress and the president had put into law the omnibus and the president bad put into law the congress and the president has put into law the omnibus crime control and safe streets act of 2001. among other initiatives, this low created the Law Enforcement Assistance Administration, LEAA, specifically t deliver on the president is promise of technological assistance. They contributed nearly N50 million to state police and local government criminal justice and law enforcement agencies to fight crime. This founding was overmatched by other federal agencies such as the FBI and he states and local government police themselves. The police man date to “assist” was broad but a large share of its technological assistance was aimed at adding the powerful tools of management science and information system on the fight against crime.
The project focuses on a particular class of computer use, searches for vital information, that constitute the bulk of police computer activity. The results suggests that computerize search capability is widely and routinely used by both patrol officers and detectives, and that such uses are valued by the police in their fight against crime.

1.1 STATEMENT OF THE PROBLEM
The chronic lack of adequate information is the paramount difficulty facing the police in the fight against crime. The lack ranges from the police chief’s shortages, of information on how to deploy the department’s limited resources, to the practical problems of each patrol officer’s uncertainty over whom to stop and question regarding suspicious behaviour. The multi faceted management system approaches of the year addressed the problem with significant payoffs.
The challenge of improving the information provided in the patrol officer in the street or the detective working a case, was not amenable to such approaches. Rather, the only source of information on how to deal with specific individuals or cases was existing records. And the only means of using those records was to “look something up” Thus, records and searching form core of the information system that support the patrol and detective functions of the police.

1.2 AIMS AND OBJECTIVES
The fundamental objectives of the computerized crime management system are;
• Improves police effectiveness in

DESIGN AND IMPLEMENTATION OF COMPUTERIZED ECONOMIC GROWTH MONITORING SYSTEM
(CASE STUDY OF FEDERAL MINISTRY OF FINANCE)

ABSTRACT

Federal Ministry of Finance has always monitoring how economic growth is moving in this Nation. After the granting of internal autonomy to regions in 1946, there have been subsequent fiscal commission, military decrees Actes of Parliaments that reviewed both dreamed earning structure for Government. In the cause of this research work”. Design and implementation of Computerized Economic growth monitoring system Federal Ministry of Finance”, economic growth as constituent of revenue allocation has been checked in relation to the Federal Ministry of Finance (F.M.F) of the sectors that contributes more percentage to the ministry economy.
Indeed, up to the time of work, the issue of economic growth increment or amendment in salary structure came to shape focus with little or no counter check consequences viz: wage and price and employment; And money multiphers. Both the tiers of Government and the various workers union have refused to be amenable to Nigeria Financial trends haven observed that in recent years, the petroleum sector has become the main stay of Nigeria economy, in the fiscal year, 1964/67. However, it’s found that computer economic.

INTRODUCTION
1.1 BACKGROUND OF STUDY
The federal ministry of finance was established in 1958 by the finance (control and management) ordinance, to replace the finance department. The ordinance conferred on the ministry the responsibility for the control and management of the public finance of the federation. In the 1080, attempts were made to re-organize the finance ministry either by existing some of its departments or ceding others to it. For example, in 1980 Budget office became an extra Ministerial Department under the executive office of the president and headed by a special Adviser to the president on Budget matters from 1987, the Budget office functioned once again under the ministry of finance and was surprised by its own merged with the ministry of National planning to form the office of Budget and planning in the presidency under ministry of state. Then in 1991, the Budget office was excised again from the ministry of budget and planning and returned to the ministry of finance where it is to date.
In the case of the customs, it was a department in the ministry of finance until 1985 when it was transferred to the Ministry of Internal Affair where it was managed under the customs, immigration and prisons services board, however, in 1992, customs was returned to the jurisdiction of the ministry of finance.
The revenue department is made up of three division namely Revenue Division, Petroleum Division and Research and Statistic Division. Given this background, the function of the department include monitoring, analyzing and reporting of the revenue inflow as from oil and non-oil revenue source.
In addition, the federal ministry of finance carries out revision exercise on monthly and quarterly basis, in respect of revenue from the sources (customs and excise including levies, company income tas, federal government independent revenue earned by Ministry / Parastatal and operating surplus from major government parastatals.

1.2 STATEMENT OF THE PROBLEM
Every organization is comprised of individuals that are recruited to offer diverse kinds of services, the cost of acquiring this task is translated into the payment made for carrying out this services.
Economic Growth Monitoring is an important aspect of any developing country particularly Nigeria, specifically. The federal Ministy of finance which is in the position to monitor and forecast Economic Growth has for

INTRODUCTION
1.1 BACKGROUND OF STUDY
Information system occupies a vital and unique position in any organization by virtue of the data and information, which it contains. Security of information is of great importance to any given organization this makes the information reliable since information stored can be referenced whenever necessary access by unauthorized persons.
This project analysis the activities and importance of securing information in any organizations and to see that the information is accurately maintained to help the management in decision making and control of the diverse activities of the organization.
The Nigeria police force is responsible for security of live and property and as a result keeps record of vital information given to them by any informant so as to enable them arrest activities or scenes unpleasant to people residing in a particular district.
Therefore, for effective administration and management, the provision of computer based information security for every source station is certainly inevitable, since it will take care of all the problems and inadequacies of the manual system.
1.2 STATEMENT OF THE PROBLEM
Inspite of the level of computation of various organizations, this particular organization on discussion is still at the grass root level. It requires a certain degree of protection especially of vital equipments, properties and information and this cannot be realized through the current system of

INTRODUCTION
How is computer and other related devices actually able to send information across data communication lines. The answer to this is the installation and maintenance of computer network. Furthermore, installation and maintenance of computer network is the glue that holds all data in the exact form, the data is to be transfer from one place to another. While the procedures for installation of computer methods are embodies in this project.

STATEMENT OF THE PROBLE
Computer hardware may fail, telephone line may fail and more likely, the computer software may have bugs that make the network stop working. How does the airlines clerk sell tickets when the computer is down? How can the pilot send a message across if the network fails? How do you get your electronic mail, pay bills, get news, if you become dependent on computer networks that sometimes fails. If you put a shaved database, you want to be sure that it will not disappear or be tampered with. It you can use home computer raid your account and toil will your money?
A company that puts all its important data in line runs the risk to go out of business if that information is boss or incorrect.
Furthermore, support the owners of a saved data based want only certain people to use it one way to limit use, is to give a password to those people alone, that will have access to it and before opening the data base, the computer will ask the user to enter a password.
Password protection is not parted, though if someone finds out your password and use it, the computer will not know that such password is been used illegally by such person.
Finally, inability of the computer scientist to observe appropriate procedure in connection during installation poses treat to them, which however may lead to damage of the computer and cards.

PURPOSE OF THE STUDY
The purpose of the study is to design a system which shall render an assistance to the computer scientist during the installation and maintenance of a compute network. Moreover, proper installation of various components of the networks are achieved and the prevention and corrective maintenance are properly added.

DESIGN AND IMPLEMENTATION OF COMPUTER BASED TUTORIAL ON AIDS AWARENESS AMONAST
STAFF AND UNDER GRADUATES OF IMT-ENUGU

ABSTRACT
AIDS has become a serious problem all over the world. Everybody need to be informed about HIV/ AIDS. In this project work, efforts have been made to inform the students and staff of higher institution of the danger of AIDS to human life. What distinguishes this work form all other AIDS awareness program is the fact that it is properly document and can be easily used by any student or staff even if the person is not a computer literate.
Also this work considered the fact that human brain sometime doesn’t store some vital information for a long time. This is because of the information filtering in the human information processing system. Because of this some feature were used in the tutorial program to permeate human filters thereby establishing the information in the mind of the user.
Also this work took an indebt look on the origin of AIDS, its causes transmission, prevention and some other current development towards the fight against its spread. When implemented it will go a long way in the prevention of the HIV spread.

CHAPTER ONE
1.0 INTRODUCTION
Despite all the awareness programs on AIDS, it is like greater number of people are still not well informed about the menace of AIDS in the society. It is guit appalling that even among the student of higher institution and some staff in the campus community that AIDS awareness program has not gone deep inside them. Most of the awareness programs are through public lecture and some other means that are not computer based. The effect of this is that, proper documentation of the lessons is not done and this has made it impossible for people (students and staff) to go back to reference such materials. Ti is impossible to determine the prevalence of HIV/AIDS in the university/ campus community because nobody to data has come out in the open to acknowledge being HIV positive in the campus and death certificates do not state whether one died of an AIDS related illness or not.
The lack of the higher institution information on the disease is attributed to inadequate record. Available records were found to be inadequate foe two principal reassure:
1. They make almost no mention of AIDS
2. They are incomplete to the extent that they do not capture the situation of the campus personnel.
Infact records that might throw height on the prevalence of HIV/AIDS on campus did not appear to be held by any of the central administration (registrar, personnel officer, etc). These lapses are addressed in this project work. This work incorporates some features that makes the awareness tutorial an interesting one. Also the proper documentation (computer based) makes it easy to reference.

1.1 STATEMENT OF PROBLEMS
A lot of people (student and staff) do not understand the relationship between HIV and Aids. Because the HIV Incubation period varies from one person to another. Some people will develop AID after about two month of up to 5 HIV. While other may last up to 5 month or more. The valve point here in that, give the long period that Inference between HIV Infection and the emergence of full- blown AID, the full extent of student HIV Infection will not unfold until students have graduated from the university/campus and entries the words of wor
