A.   Background of the Study
          Children during their early stage of learning are curious on how things around them work. They always want to play outdoor games such as tumbang preso, patintero, piko, jolens, pogs, and many other games with their playmates. These games require touching and a lot of barefoot running. Children do not tend to know that running barefooted will cause the formation of ascaris and other parasitic worms that might infect their intestines. Malnutrition surrounds our country today; a lot of people, most especially the children, were the victims of it. One of the most common causes of malnutrition of children is worm infestation.
          Worm infestation can result if there happened to be a direct or indirect contact with the feces of an infected person. It can be dispersed when the feces of an infected organism are used as fertilizers in farmlands that are now converted into urban type of community. The kids that are living in that converted area can accumulate the infection that the former farmland has. 
Children that are infected can have parasitic worms inside their bodies. They can eventually experience malnutrition and other health deficiencies if not treated. Purgative medicines are cheap in cost but children dislike the taste because of its bitterness. The researchers came up with this project due to the desire of helping the parents of infected children in convincing their kids to take good-tasting purgative remedy that is cheaper in cost and can be done at home. The researchers found out that pounded and boiled akapulko seeds are used as an effective purgative agent.  Akapulko is an herbal plant that can be used in curing skin, stomach, lung, and mouth problems, and is well known for its sudorific, diuretic and purgative characteristics. It can be ingested without having any side effect or contraindications. The researchers thought of pulvoron, being a healthy, delicious, and attractive treat for all. The akapulko seeds were consider as extender in place of the traditional rice crisps, nuts, or nougats in the pulvoron. Established that akapulvoron could be an effective and safe purgative treat, the researchers intended to conduct a sensory analysis of the product to determine if it would be generally accepted by the public.

Makahiya (Mimosa pudica) Root Extract as an Alternative Ovicide against Dengue Mosquito (Aedes aegypti) Eggs

Significance of the Study
The augmenting number of Dengue cases not only in our country but also to other countries all over the world experiencing the abnormal change in weather is not of recent origin to us. Along with this difficult situation, there are two-winged, dipterous insects that hatch their eggs for a short time, reducing the size of their larvae and become “nervous-biters”.    In that case, they are harder to intercept in flight that is why it is more advisable to focus on the places where they lay their eggs.
      The researchers conducted this study in order to lessen the proliferation of mosquitoes or prevent the eggs from hatching using the Makahiya Mimosa pudica roots extract as an ovicide. As the experiment was proven to be effective, it is relevant to propagate the plant for mass production and communicate the results to other people. It is also significant to conduct experiments about the other potentialities of  the said plant, such as the anti fertility property of its root extract which was  proven in Albino white mice sperm cells according to Dr. Godofredo Umali-Stuart of University of Santo Tomas.

Prototype Biometric Security System on Personal Computer Using Fingerprint-based Power Switch

 Researcher: Maycee Anne Rufino
Research Adviser: Mrs. Ma. Regaele Olarte

Statement of the Problem
The study sought to devise a system to protect every computer from hacking and unwanted file sharing due to usage without permission by unauthorized users. The researcher utilized fingerprint-based biometric security system on the power switch of personal computer, thus making it unquestionably “personal.”
            Specifically, the study aimed to answer the following questions:
1.        How should the system be designed and developed in order to:
a. Secure the user’s data from hacking or sharing,
b. Provide an account security for the computer user,
c. Ensure that the system is protected against alteration and not prone to errors?
2.        What is the level of performance of the system based on the following criteria:
a.  Reliability
b.  Accessibility
c.  Efficiency
d.  Functionality?

The fingerprint-based biometric security system on personal computer with remote access for the private user is effective in terms of the specified criteria.
Scope and Limitations
The fingerprint-based biometric security system on personal computer is more accessible, secured, accountable and accurate. It is in the registered fingerprint where an account is created for hassle-free admission to the system. Furthermore, transactions do not consume much time and effort since the information needed to connect and to access one’s account is already automated.
The following were the scope and limitations of the study:
  • The study only focused on the general transaction of database and of safe-keeping for the data-security of personal computers.
  • This mechanism was not advisable for shared computers but merely for personal use, as only an authorized person could gain access on the most important data and information stored in the computer.
  • The system would not operate if the user is unauthorized or unregistered. Only authorized user with registered thumb mark and password can get into the system.
  • This device can register and hold up to five authorized users only to access the system.
  • The fingerprint-based power switch can also be used on any technology containing switch. (e.g. lighting, appliances, motorcycles etc.)

            Water hyacinth is an aquatic plant which could well be used, instead of wood, in generating an alternative source of energy. The processing of water hyacinth into briquette would have a significant role not only in the development of an alternative fuel, but also in the preservation of the environment. The water hyacinth that was harvested, dried, and pulverized was mixed with cassava starch and acacia seed binder by being compressed into briquettes in a manually-operated machine. The experimental set-up made use of dry and fresh water hyacinth while a traditional charcoal served as the control. In all the quality tests done, T- test showed that there was no significant difference between the experimental product and the commercial product in terms of various parameters, at 0.05 level of significance. The results of experimentation and data analysis showed that the experimental product is just as effective as the commercial briquette, with better potential of helping the environment by reducing the negative consequences brought about by water hyacinth’s rapid profusion. Thus, the environmental briquette made from water hyacinth with acacia seeds as binding agent could be an effective alternative to the traditional charcoal made from burning of wood.
