In general, land information includes all information that is related to the land and its resources. Among the necessary considerations in the design and development of a land information system, the topological aspects are fundamental as they refer to the interconnectivity of the information. Graph and information theoretic considerations, based on the natural topology of the information, are also required for system analysis, optimization and other purposes. Some practical aspects of these considerations are briefly discussed with suggestions for further studies and investigations.

The present study is a Type 1 design and developmental research (DDR) study that aims to analyse the situation, design, develop and evaluate an instructional Place-Based Process Genre Module (PBPGM). Upon completing the needs analysis, design and development of the module, it underwent a pilot test. The validity and reliability were then conducted. A panel of experts were involved in determining the validity of the module's content, sessions, and activities. A group of 30 ESL learners were involved in determining its reliability. All content, sessions and activities were rated above 70%, and all sessions and activities were rated over alpha value of 0.70 indicating that PBPGM was valid and reliable to be experimented with.

<p>A research has been conducted which aims to design a waste-based calorimeter as an alternative to measuring heat for chemistry practicum in schools. Research products developed through the steps of design-based research comprising the steps of analysis, design, and development. The resulting product is a waste-based calorimeter equipped with an automatic stirrer. The container to store the reagent solution on the calorimeter is made of Styrofoam, paper, plastic, melamine, PVC and bamboo. Optimization tool was conducted to determine the heat capacity of the calorimeter and the enthalpy of neutralization. The highest accuracy calorimeter value between 78-97%. Bamboo calorimeter has the highest accuracy value (97%). Styrofoam calorimeter has the lowest accuracy values (78%). Based on the results of the validation and feasibility test it can be concluded that the product is declared valid and feasible.</p>
