1. Why do we study ethics?
Morality or ethics is one of the main subjects of philosophy, which focuses on the morality of human society. Delineate what is right and what is wrong. If it is easy to explain what ethics means to be separated from the good from the bad, why we should learn about ethics because learning ethical action is right or wrong according to society, culture and traditions of happiness?
2. Why should we be concerned about doing “the right thing”?
Doing the right thing is to make a social convention by which people in society recognize the need and the peace of society, free from bias and corruption to society.
3. If each of us has a unique set of influences and values that contribute to our personal value system, how can that are applied to a community as a whole?
The Personal Values to social participation is difficult, if our thinking is not good enough, and contrary to social ethics. But it's not that impossible, if we know how to convince people in the society and present the advantages and disadvantages that will be followed for everyone to learn our thoughts may be influenced by a small group to big society is not difficult.

This chapter presents the background of the study, statement of the problem, significance of the study, hypothesis, scope and limitations of the study, and definition of terms.
BACKGROUND OF THE STUDY
Knowing the economic condition of the beneficiaries’ before the program could determine how much improvements were achieved by the respondents as the 4Ps come into their lives. Thru looking in the comparison of the economic status of the beneficiaries in two separate times, progress therefore could be specified and directly measured in terms of the changes the beneficiaries have achieved after the effect of the program.
The real scenarios before the coming of the program in the world of the poor beneficiaries was really a tragedy in the first glimpse but for them those scenes were just very ordinary as they appear in a daily basis. Feeling the pitiful conditions of most Filipinos who belonged to the poorest of the poor life state was a great pinch to the heart of an observer. By looking on the factual evidences, prior to the implementation of 4Ps one could then realized how much progress was obtained and how much had been contributed by the program to the intended beneficiaries. The quality of life and living of every Filipino citizen within the poorest economic state suggest that these must be an action of the government to at least ease the extreme difficulty they have felt. 4Ps...

The transmission of information between a sender
and a recipient. (p. 17)

The act of putting a message in terms that are
understandable to others. (p. 17)
communication channels
The various ways in which a message can be sent,

LO1 Explain the importance of excellent business communication
Effective communication happens when relevant meaning is transmitted from the sender
to the receiver. Skillful communicators save time and money and develop deeper, more
trusting relationships with their colleagues. Anything that interferes with the correct transmission of your message is a barrier to communication. Barriers can be physical, verbal,
nonverbal, personal, cultural, perceptual, or organizational. To communicate effectively,
you should be able to identify and surmount any barriers that stand between you and your
audience. The result? Greater long-term success in every aspect of business.

INTRODUCTION
Background of the Study
Computerization is a control system that manages processes in industrial workplace. It reduces human errors and processing time, thus it can boost productivity and result into high quality of product produced. In Information System, computerization is concerned about interrelating different but interdependent transactions. This can result in a system with well-integrated processes that can perform faster and more accurate than a manual system.
Enrollment is the process of entering and verifying data of student to register on a particular school. Different interrelated processes build up enrollment procedures called Enrollment System. Enrollment Systems (ES) are used particularly in recording and retrieving student’s information. Tracking student’s information is also one feature of ES, in which the school can trace the standing of a student. Enrollment System is a good example of a computer generated process.
The Computerized Enrollment and Student Record System that the researchers have proposed is for the school, Philippine Scholastic Academy. It was established at August 7, 1917 under the name of Quiapo Anglo Chinese School at Echague, Quiapo Manila. In 1924, the Quiapo Anglo became an extension of Chinese National School in Binondo. The school had its formal opening in a building at Villalobos St. in Quiapo in July, 1945. Due to an order from the Ministry of Education Culture and...
