In this paper, a new transposition cryptosystem scheme is proposed, in which a rotation session key is designed for a mobile user to secure access in multiple sessions of mobile text chatting (MTC). This is a block cipher adopting a classical substitution combined with text-matrix rotation operation in order to enhance the protection of MTC over the Internet. The scheme is entirely dependent on the only secret key. The session key is designed by a pseudo random function the input of which is the length of secret key. Characterized by easy and fast computation, this scheme is expected to be low-cost cryptosystem. Finally, its security is strong compared to other approaches under the frequency analysis.
Key terms: mobile text encryption; block ciphers; secret key; session key; classical substitution; transposition scheme; key management.

The study intended to map out the communication patterns in an academic institution in Batangas City. Research findings showed that variations in turn taking rules are often influenced by the interactants’ position in the organization and the role they play in the meeting. Moreover, in terms of the shared power, interactants who caused the highest number of overlaps is the most powerful speaker, while interactants who executed the least number of overlaps are considered powerless. But since the conversation is based on the concerns and roles played by each office, interactants who had less concerns or less roles shared less information, too. Therefore, the least number of neither turns nor overlaps cannot be qualified as powerlessness. Furthermore, interactants who often use pauses and fillers were the ones powerless in the meeting. However, this study also revealed that not all hesitations indicate powerlessness in conversation; it could be done for a purpose. Also, hesitations represented by fillers, though indicates powerlessness, can be classified as speakers “discourse mannerisms”. In addition, power in the conversation can also be measured through the use of emphasis. Interactants who used emphasis in his/her discourse is someone proven to be the most powerful in the conversation. Essentially, the study endeavored the institution be aware of the impact of the use of the informality of language and specific discourse styles. The department’s informality in discourse might be strength today, but could be an ineffective strategy in the long run.

This study aimed for full understanding of the concepts of irreversibility, universality, finality, causality of death and Filipino children’s other concepts of death. This study made use of 30 children, ages 7–11 as the participants, utilized semi-structured questions, and drawing exercises. Findings show that the development of concept of death among Filipino Children is not a single construct and requires understanding the different concepts of irreversibility, universality finality and causality of death. Understanding these concepts require understanding of non-corporeal continuation, dys-functionality, all-inclusiveness, unpredictable, inevitable, immobility, and insensitivity. Children understand that sickness, tragedy or accidents and personal conflicts are conditions that really do or can bring about the death of a living thing. Filipino children’s other concept of death is their belief in the divine providence (pagpapasa-Diyos) and old age. The concepts of death among Filipino children is regarded as either concrete or abstract and it continues to evolve towards maturity through socialization, personal experiences and children’s observation in the environment.
Key terms: irreversibility, universality, finality, causality

This paper considers the ways in which the people of Isla Verde come together and interact over extended periods. Firstly, it offers a brief description of the island in terms of its physical and socio-economic dimensions. The significant implications (for family, government, religion, education and business, in both the formal and informal sectors) of the Filipino spiritual culture of trust (tiwala) are then considered in terms of environmental protection, and individual and community empowerment. It is a phenomenological study using the culturally-rooted “pamamaybay” approach (Odal, 2001), i.e. ‘kapwa-oriented’ research. Pamamaybay is a reflective journey towards a full understanding of trust (tiwala). Isla Verde’s biodiversity is amongst the highest anywhere. The island is well known internationally as a “Centre of Marine Biodiversity in the World” and locally as a peaceful and harmonious community. People on the island exhibit aspirations, achievements, creativity and positive responses to the many challenges and circumstances of their life. Their creativity shows a unique capacity to produce anything needed for life, work, livelihood and purpose of existence. This research has led to the discovery and appreciation of characteristics of the Isla Verde people, particularly, peace and happiness in their personal and community life. This brings people hope and cultivates aspirations for their social well-being. This spiritual culture of trust has inspired the people to be empowered to work on the attainment of their deepest hopes. Empowerment is complementary to social development. Social well-being is key to social development and the primary means to this is identification of the goal, “What kind of nation do we want for our future generations?”

Specifically, it aimed to present the demographic characteristics of Quick Service Restaurant operating in San Pablo City, Laguna; describe the operational efficiency of Quick Service Restaurants in terms of service; test the significant differences of the responses when grouped according to demographic characteristics of Quick Service Restaurants as well as the significant differences of Quick Service Restaurants according to service; and lastly, propose strategies to enhance operational efficiency. The descriptive method of research was utilized to assess the Operational Efficiency of Quick Service Restaurants (QSR) in San Pablo City, Laguna. The respondents of the study were five (5) managers and 150 selected customers of Quick Service Restaurants in San Pablo City, Laguna which represents the total number of the selected respondents of Quick Service Restaurants. Based from the findings, the following conclusions were drawn. First, among top five (5) Quick Service Restaurants in San Pablo City, Laguna, in terms of location, McDonalds and Mang-Inasal are only within the mall, McDonalds has been operating for more than 10 years, Jollibee, McDonalds and KFC have the highest customer seating capacity, while Jollibee has the most services offered and has a 24 hour service operation; also, Jollibee and McDonalds have the highest number of transaction counts per day. In terms of products, juices are common and preferred to be ordered by most of the customers in Quick Service Restaurants, while coffee is least preferred. In rice- based products, still the combination of chicken and rice is on the top, while ice cream has always been a favorite of most customers regardless of their age. From the study, it was also revealed that among the Service parameters which are time, timeliness, responsiveness, accuracy, completeness and courteousness, it is the time of waiting for the food ordered is always experienced by most of the customers. There is a significant difference on the responses when grouped according to Quick service Restaurants as well as there is a significant difference in the responses when grouped according to demographic characteristics and service of QSR’s. This means that the services provided by the QSR’s varry and proposed strategies to increase operational efficiency were given based on the output of the study. Recommendation was made such as reviewing of service parameters particularly time by launching or intensifying a pet project that will enhance service skills of the employee; specifically, their speed to avoid long waiting. A reward and recognition system was also recommended in order to motivate employees and be involved to their fullest in optimizing operational efficiency. Furthermore, the proposed strategies maybe utilized after being presented to QSR managers.

This paper delved on the relationships among the four dimensions of performance of the commercial banking sector – gross income, effi-ciency, profitability and growth. Measures of gross income, profitabil-ity and growth were calculated from banks‘ audited financial state-ments. To validate the data and get updated figures for 2009 and 2010, actual interviews were conducted with officers in charge of finance and investment relations of six (6) big banks. Pearson correlation coeffi-cient was used for statistical treatment and analysis of the data. The study revealed that the following relationships were significant: (a) two measures of profitability - Return on Assets before income tax (ROA1) to Return on Assets after income tax (ROA2); (b) profitability (ROA1) to efficiency (net interest income), (c) efficiency - net interest income to overhead costs. However, the following relationships were not significant: (a) efficiency (overhead cost) to growth and gross income; (b) asset growth to deposits growth and gross income; (c) gross income to deposits growth; and (d) gross income to profitability and efficiency.

Taal Lake is within the protected landscape area under RA 7586 or National Integrat-ed Protected Areas System (NIPAS). It is recognized national water endowed with unique biodiversity which is important to ecology and economy of the region, in particular, and national fisheries, in general. It is therefore imperative that regular monitoring is conducted on critical parameters indicative of quality of lake water ecosystem. This study probed eutrophication of Taal Lake and river tributary specifi-cally nutrient loading in Wawa River in Tanauan City, one of the 37 tributaries of the lake. Experimental samples were analyzed for nitrogen (N), in terms of nitrates/ammonia and phosphorus (P), in terms of phosphates. Supplementary data from previous reports made by Philippine Fisheries and Environment bureaus were also presented. Using DENR AO (DAO) 34 s. 1990 as standard, by and large, there is noted increase in the P level of water in the lake and river tributary and while no recommendation for N level yet, per Class B standard, values are indicated by experi-mental samples. Though the study did not cover all the tributaries, it is noteworthy to describe that river eutrophication is evident. The quality of river tributary directly affects the quality of water in Taal Lake. This however challenged DENR Memoran-dum Circular No. 2001-09 which classified Taal Lake as Class B water intended for tourism and recreation. It is recommended that a proactive environmental program such as the practice of aquaponics be introduced in order to utilize and recycle nutri-ents in lake‘s water due to aquaculture as well as industrial/commercial activities or until long-term mitigating and environmental policy measures have been explored.

Field practice in education is the core of transmitting theoretical knowledge into practical level of work. Theorists and practitioners support the im-portance of culture in field education particularly in unexplored areas such as the mechanisms and factors that may influence educational practices. Field work is a learning opportunity that provides a sense of scale (spatial and temporal) of earth phenomena and processes. This research was conducted to find out the importance and challenges of graduate students‘ fieldwork expe-riences and use them as basis in skills development as teacher practitioners, research scholars, and educational leaders. The researchers utilized a descrip-tive Husserlian phenomenological strategy aimed to identify structure of experiences as described by the participants. The researchers have explored the individual- lived experiences and expertise of the key participants through questionnaires and unstructured interviews. Fifteen (15) Science Education doctorate students were the participants of the study. They were chosen as respondents due to their teaching skills and experiences, and their understanding of the importance and challenges of fieldwork in science education. The responses of the individual participants were analyzed and categorized by theme to design a framework necessary to improve the sci-ence education graduate program in the university. The results of the study showed that fieldwork contribute to the graduate students‘ skills develop-ment as teacher practitioners, research scholars and educational leaders. The researchers have also identified five common difficulties in implementing fieldwork such as time and schedule, unclear framework and plans, job-related activities, health-related issues and availability of laboratory facili-ties. Using the Fieldwork Experience Model as derived from the study, any institution can use fieldwork to develop essential skills among research scholars, teacher practitioners and educational leaders.
