I have chosen to watch the movies Equilibrium and The Fifth Element and below are the reactions that I have on watching those movies.


Equilibrium

If you would try to watch this movie, I think you would think that this is kinda boring because when I watched it, I feel like I wanted to click stop on the video player and try another movie. But when I started to concentrate on it, I have realized that this movie is worth watching for especially that it talks about how would the future be or how would we live in the near future. I felt very excited during the middle part of the movie since it was when the main actor had stopped taking his Prozium, a liquid drug that could stop feeling emotions, and later felt the feelings a normal human being has. It was so pitiful for those people who were executed just because they have felt emotions. In the movie, the people in place call Libria believes that human emotion is responsible for man's inhumanity to man, and made the new leaders ban all materials deemed likely to stimulate strong emotions, including art, music, and literature. Those materials are rated "EC-10" for "emotional content" and are typically destroyed by immediate incineration. It was very overwhelming to watch the part where the main actor had decided to continue not taking the Prozium and be with those people who are resistant to the policies existing in Libria, which they are called “The Underground” since they were living under the grounds of Libria. Since the main actor is Libria’s highest ranking cleric, it is exected that he is well-trained on a deadly martial art of Gun Kata, an art which teaches users to predict the actions of opponents during firearm combat. And by that, he killed those people behind the Tetragrammaton Council who were governing the city of Libria and all became well.


The Fifth Element

When I started to watch this movie, I remembered that I have already seen this a very long time ago and I think I was not able to understand the details of the movie since I was just a kid on that time. I can say that during the first part of the movie, I already felt excited and interested on watching this since I love watching movies involving the universe, astronomy and the like. The main goal of the main actor and actress in this movie is to save the world. At first, Dallas did not want to believe that his mission is to save the world. When he won a ticket on a contest which has a price of having a vacation on Fhloston Paradise, he never expected that aliens would be there interrupting the show. Speaking of the show, it was the most amazing part for me, a Diva that was singing in a high-pitched tone of voice. Oh, I wish I had that wonderful voice also. So much for that, I felt like I was inlove watching Dallas and Leeloo kissing and embracing each other that made Leeloo realized that the human beings are worth saving for and had released the weapon’s “Divine Light which caused the Great Evil (Black Hole) to stop hitting the Earth and become a new moon in Earth’s orbit. After watching this movie, I remembered how the Earth had been destroyed on the movie entitled “2012”. I think they have similar story also with the movie entitled “Deep Impact”. All in all, this movie is really amazing.


COMPARATIVE ANALYSIS

Both movies are of course categorized as a Science Fiction Movie. Both are also nice and worth watching for. The movie Equilibrium is more engaged to political views since it talks about how society would become in the near future if war would be existing. Meanwhile the movie The Fifth Element talks about saving the world through having the five elements combined to stop the evil going through Earth. Both talked about love. In the movie Equilibrium, the actor and his children realized that it is not right to take the liquid drug and that they have started to stop taking it when the actor’s wife has been executed after being revealed to be a sense offender. And in the movie The Fifth Element, it was saying the word “I need you because I love you”, the embrace and the kiss that made Leeloo strong enough to perform her role as the fifth element that could save the world.

Since I have started to learn what my profession really is, and if I would think of what would be my contributions for the development of technology on what I have learned from college, the first thing that would come on my mind is I would like to work with the security issues in systems. According to Wikipedia, Computer security is a branch of computer technology known as information security as applied to computers and networks. The objective of computer security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accessible and productive to its intended users. We all know the fact that information security is not yet as perfect as we wanted it to be. There would still be ways to hack systems nowadays and that’s why I would really want to contribute ways for the data and systems security to be perfect like no one could really get through the systems without permission.

Enumerate reasons why we use technology today. What are some points that have influenced us? What are the factors involved in technology change?

Technology is the set of tools both hardware (physical) and software (algorithms, philosophical systems, or procedures) that help us act and think better. Technology includes all the objects from a basic pencil and paper to the latest electronic gadget. Electronic and computer technology help, use and share information and knowledge quickly and efficiently. What was previously slow and tedious is now easier and more realistic. Any tool has the potential to remove the tedium and repetition that will allow us to perform that which is most human-- thinking, dreaming, and planning.

We use technology for the following reasons: (1) help us act and think better; (2) quick and efficient information dissemination; (3) ease of work; (4) profit; (5) faster transactions; etc

The points that have influenced us in using technology are: (1) curiosity; (2) today’s trend; (3) making life easier and better; etc

There are also factors that are involved in the change of technology and some of those are the following: (1) new ideas; (2) creativity; (3) uncontentment ; (4) people’s demands and needs; etc.

SAD 2 - Assignment 4

Contrast and discuss the enrollment input form (PRF) with the enrollment university interface.















When you try to look the Pre- Registration Form (PRF), it seems that it has many differences with the interface of the university's enrollment system. There are entries or fields on the system that is not present on the PRF that a student must fill-up. And some of those entries are the following:
  • Civil Status
  • Birthdate
  • Contact Number
  • E-mail Address
  • Religion
  • Desired Career
  • Year
  • Parents
If the entries above are not present on the PRF, then what would be the values to be inputted on that fields? If a student is an old type of student, then maybe those fields have already values but what if he/she is a new type of student? What should be those fields have?

Aside from those missing fields that I have observed, there is also a big difference on the positions of the different fields that the PRF and the enrollment system interface have. If I would be the encoder, and assuming that it would be my first time to operate the system, it would be difficult for me to input the values found on the PRF to the system since I have to look to the PRF and then find the correct field on the system where I have to enter the values. It would be time-consuming and there is a possibility of wrong inputs for those fields.

I also found out that the PRF has something to do with the scholarship a student has but in the system, there is no field for the scholarship. Aside from that, the employment information is also not present on the enrollment system interface.

My suggestions would be: (a) the look and feel of the PRF should be close to the look and feel of the university's enrollment system interface so that it would just be easy for the encoder to encode the necessary information found in the PRF into the system; (b) some entries that are present on the system and are not on the PRF should be removed.

SAD 2 - Assignment 3

Interview your university network specialist. Ask how various parts of the system communicates with each other throughout the university. (Q) Given the chance to redesign the existing setup, enumerate and discuss your keypoints for an effective and efficient network environment ideal for the university.


1. What are the components involved in the system(s) in the university? (hardware, software, technology, etc.)

I am not in the right position to discuss the details of the software components used as there are other assigned personnel for such job. However, talking about hardware component and technology used, basically I, assigned as the network administrator, is entrusted to maintain our different servers to run 24/7. Currently, we have our Web Server hosted here in our University in our HP ProLiant ML350 Server. Its an old but stable server set-up here in our Networks Office and has been active since Engr. Val A. Quimno , not yet a dean, was appointed as the Network Administrator. The said server has the following specification:

* Intel Xeon 3.0 GHz, 3.2 GHz, or 3.4 GHz processors (dual processor capability) with 1MB level 2 cache standard. Processors include support for Hyper-Threading and Extended Memory 64 Technology (EM64T)

* Intel® E7520 chipset

* 800-MHz Front Side Bus

* Integrated Dual Channel Ultra320 SCSI Adapter

* Smart Array 641 Controller (standard in Array Models only)

* NC7761 PCI Gigabit NIC (embedded)

* Up to 1 GB of PC2700 DDR SDRAM with Advanced ECC capabilities (Expandable to 8 GB)

* Six expansion slots: one 64-bit/133-MHz PCI-X, two 64-bit/100-MHz PCI-X, one 64-bit/66-MHz PCI-X, one x4 PCI-Express, and one x8 PCI-Express

* New HP Power Regulator for ProLiant delivering server level, policy based power management with industry leading energy efficiency and savings on system power and cooling costs

* Three USB ports: 1 front, 1 internal, 1 rear

* Support for Ultra320 SCSI hard drives (six hot plug or four non-hot plug drives supported standard, model dependent)

* Internal storage capacity of up to 1.8TB; 2.4TB with optional 2-bay hot plug SCSI drive

* 725W Hot-Plug Power Supply (standard, most models); optional 725W Hot-Pluggable Redundant Power Supply (1+1) available. Non hot plug SCSI models include a 460W non-hot plug power supply.

* Tool-free chassis entry and component access

* Support for ROM based setup utility (RBSU) and redundant ROM

* Systems Insight Manager, SmartStart, and Automatic Server Recovery 2 (ASR-2) included

* Protected by HP Services and a worldwide network of resellers and service providers. Three-year Next Business Day, on-site limited global warranty. Certain restrictions and exclusions apply. Pre-Failure Notification on processors, memory, and SCSI hard drives.

Aside from it, our mail server running under Compaq Proliant ML330 Server, our oldest server, is also hosted here in our Networks Office. Together with other Servers, such as Proxy and Enrollment Servers, both proxy and our enrollment servers are running in a microcomputer/personal computers but with higher specifications to act as servers.

2. How do these communicate with one another? (topology, network connectivity, protocols, etc.) – may include data flow/ UML diagrams to better explain.

All Servers are connected in a shared medium grouped as one subnetwork. In general, our network follows the extended star topology which is connected to a DUAL WAN Router that serves as the load balancer between our two Internet Service Providers. All other workstations are grouped into different subnetworks as in star topology branching out from our servers subnetwork as in extended star topology. At present, we are making use of class C IP Address for private IP address assignments. Other workstations IP assignments are configured statically (example: laboratories) while others are Dynamic (example: offices). All workstations are connected via our proxy servers that do some basic filtering/firewall to control users access to the internet aside from router filtering/firewall management. So, whenever any workstation has to connect to the internet, it has to pass through software and hardware based firewall.

3. What are the processes involved in the communication (each system to other systems)?

As mentioned above, in item 3, all workstations are connected via a proxy server. It means that whenever a workstation is turned on, it requests for an IP address from the proxy server (for dynamically configured IP address) and connect to the network after IP address is acquired. As connection is established, each system can now communicate and share resources within the same subnetwork and to server following the concepts discuss in your Computer Network Class.

4. How do you go along with the maintenance of the system?

Basically, our servers are expected to be in good condition since it is required to be up 24/7. Daily, during my vacant period, monitoring on the servers are observed that includes checking logs, checking hardware performance such as CPU health, etc. If problems are observed, remedies are then and then applied. Once in a week, regular overall checkup is observed as preventive maintenance to ensure not to experience longer downtime if possible.

5. Does the system follow a specific standard? Explain Please.

As I was appointed as the Network Administrator, everything was already in place except for some minor changes. Basically, different networking standards was already observed such as cabling standards, TIA/EIA 568A-B, different IEEE standards as discussed in your Computer Networks Subject, etc.

6. How is the security of the system? Are there any vulnerabilities? Risks? Corresponding mitigation techniques? Access control?

As I have mentioned, we have implemented both software and hardware based filtering/firewall. Basically, Risks or vulnerabilities and different mitigation techniques were considered to increase security in our network. Aside from filtering/firewall, constant monitoring on networks activity also increases the security of the system.

7. Are there any interference? During what (most) times do these occur? Explain their effects especially with regards to the business of the university?

Major Interferences are normally encountered as an effect of unforeseen and beyond our control events such as black outs, and the like. The said interference would of course affect University’s day-to-day businesses for obviously this will paralyze all our activities that rely on electricity and further this might cause damage on our network devices, etc. that may later be the reason for longer downtime. Problems encountered by our providers such as connection to the National/International Gateway also affect University’s business such as correlating to University’s Business Partners outside and within the country.

SAD 2 - Assignment 2

Relative to your answer in Assignment 1 .... what's your take on the design of the enrollment system?

All of the observations, comments and suggestions about the new enrollment system implemented this year are already posted in my Assignment 1. And based on it, I would just summarize my take on the design of the newly implemented enrollment system.

The enrollment period plays a big role on a university since it is the time that students would be registering as a part of the institution. As my part as a student, the enrollment procedure of the university should have a process that is easy for us to adopt, understand and follow. It is my fourth year of staying here in the university and I observed that for that past seven enrollment periods (2 times for every year) that I have experienced, it was not that easy to adopt and follow. The process is always changing and I know for the fact that it is for the betterment of the process since lots of students and other people involve in the enrollment process have many complaints about it and by that, we all want change. However, changing the enrollment process can make the people involve confused. Fortunately, diagrams were posted on the different areas on the university every enrollment. Those diagrams show the process for the enrollment and serve as a guide for the students, especially for the freshmen students, since they are new comers to the university.

The following are the necessary changes that should be implemented for the improvement of the new enrollment system of our university.

  • the first step, which is the students accounts part, can just be removed since the processes involve on it, which are checking students accounts and checking balance, are already involve on the clearance signing part that is usually done weeks before the end of a semester.
  • on the third step, the payment of the other fees (e.g. local council, OCSC, headlight, insurance) should be done prior to the presenting enrollment requirements for the advising/pre-registration part since receipts for the other fees should be included on the advising part for the adviser to be able to give a pre-registration form to the student.
  • on the sixth step, which is the last step on the diagram, should not serve as the last step since we all knew that we have to go to the library after having the official Certificate of Registration (COR).

SAD 2 - Assignment 1

Assuming you were tapped by the university president to evaluate the new enrollment system implemented this semester, enumerate your observations/comments and suggest possible areas and ways where improvements can be made. Your observations/suggestions should be properly validated with facts and literature.


The enrollment period plays a big role on a university since it is the time that students would be registering as a part of the institution. As my part as a student, the enrollment procedure of the university should have a process that is easy for us to adopt, understand and follow. It is my fourth year of staying here in the university and I observed that for that past seven enrollment periods (2 times for every year) that I have experienced, it was not that easy to adopt and follow. The process is always changing and I know for the fact that it is for the betterment of the process since lots of students and other people involve in the enrollment process have many complaints about it and by that, we all want change. However, changing the enrollment process can make the people involve confused. Fortunately, diagrams were posted on the different areas on the university every enrollment. Those diagrams show the process for the enrollment and serve as a guide for the students, especially for the freshmen students, since they are new comers to the university.














As a student, I can really say that posting those diagrams can be a big help for us not to be confused and to know what processes should be taken for the enrollment. And this assignment that we will be answering in this forum is related to that enrollment process that can be found on those diagrams. Some issues were taken on considerations for the improvement of those diagrams. But those issues would only focus on the enrollment process of the freshmen students since the old students were already used to the different processes on the university. And for the shiftees, since they have the same enrollment process with the new students, I have just generalized the enrollment process. There are some observations, comments, and suggestions that I have to share to everyone and those are the following:


In terms of the images:














1. I have observed that the picture of the student on the beginning part of the enrollment process is different on the image of the student when he/she finishes the enrollment or is now officially enrolled. It should be taken into consideration since on the reality; a student who would be enrolling would not become big or will not enlarge his/her body size on the time that he/she has finished the enrollment procedure. Maybe, it was used to emphasize that a student is now officially enrolled but it is really a little bit funny if applied into reality. If that is the case, maybe by now I am already fat (how I wish! LOL ).













2. On the long arrow pointing below that can be found after the step four of the enrollment process. For me, it can really make students confused since that arrow is pointing down and it would make us think that the next step to be followed can be found below the previous step. But as you can see on the diagram, it is not, is it?
In terms of the process:













1. The first step, which is the students accounts part, can just be removed since the processes involve on it, which are checking students accounts and checking balance, are already involve on the clearance signing part. As a student, I know that every time we will be having clearance signing, out student accounts and balances were already checked by the bookkeeper. Of course, if the bookkeeper found something incomplete on the accounts, he/she would not be signing the clearance. So, on the enrollment process, the first step can be not included since the clearance should be already completely signed prior to the enrollment period because of the fact that the people involve on the clearance signing (people who will sign the clearance, e.g. registrar, bookkeeper, etc.) are already busy on the enrollment time so they should not be disturbed for them also to concentrate on the enrollment process alone.














2. On the third step, which involves presenting enrollment requirements, advising, paying other fees, encoding, assessment of fees, and temporary COR printing, the payment of the other fees (e.g. local council, OCSC, headlight, insurance) should be done prior to the presenting enrollment requirements for the advising/pre-registration part. I have suggested it so that the process would be shorter and I know that the receipts for the other fees should be included on the advising part for the adviser to be able to give a pre-registration form to the student. On should be checked so that on the registrar part, students are already assured that they have already the receipts for the other fees.














3. On the sixth step, which is the last step on the diagram, should not serve as the last step since we all knew that we have to go to the library after having the official Certificate of Registration (COR). The library part should be included as the last step on the diagram for the enrollment. The library part should include presenting the COR for validating that a student is officially enrolled and presenting a 1x1 ID picture for the library card.
