Thus, this study was designed to assess the performance, profitability, and interaction effects of planting methods (direct seeding and transplanting) on three hybrid glutinous corn varieties (Purple Sweet, Violeta, and Honey Purple) grown in La Union. The study employed a strip plot design composed of three blocks. The two different planting methods were the vertical factors, while the three hybrid glutinous corn varieties were the horizontal factors. From January to April 2021, this research was carried out in Damortis, Santo Tomas, La Union. The two methods of planting proved to have significant influenced on the performance of hybrid glutinous corn varieties. Highly significant variations were observed on the day after sowing to seedling emergence, while significant results were noticed on seedling survival, days after sowing to silk initiation, and days after sowing to harvesting. The three hybrid glutinous corn varieties revealed highly significant on plant height, days after sowing to silk initiation, days after sowing to harvesting, ear diameter, and number of developed kernels. whereas on the parameters percentage of corn produced tillers, number of tillers per plant, number of leaves of the main stem including tillers, number of ears, cob diameter, and dry weight of upper biomass, significant differences were noted. All parameters evaluated observed no interaction variation.Item A community empowerment development plan fro government-assisted housing projects in the province of Ilocos sur(Don Mariano Marcos Memorial State University -Open University System, 2024) Buquing, Donna Michelle T.The study aimed to create a Five-Year Community Empowerment Development Plan for the homeowners of Government-Assisted Housing Projects in the Province of Ilocos Sur toward inclusive, safe, resilient, and sustainable human settlements. A descriptive method of research was used in the study. Statistical tools used were frequency counts, percentages , 5-point Likert scale and weighted means. The study focused on the Core Shelter Assistance Project beneficiaries from the Municipalities of Caoayan and Santa and from Vigan City in the Province of Ilocos Sur. Purposive sampling was used to select target respondents. The study showed that homeowners display a moderate level of knowledge on inclusivity, high levels of knowledge in safety and security, and resiliency, and a moderate level of knowledge in sustainability. Their attitudes generally agree on indicators related to inclusivity, safety and security but appear undecided on indicators of resiliency and sustainability. Similarly, their practices are moderate in inclusivity, security and safety, resiliency, and sustainability. The topmost problems encountered by homeowners include accessibility issues for inclusivity, non-issuance of certificates of occupancy for safety and security, economic challenges for resiliency, and hesitation in accessing social protection programs and services for sustainability. The study concludes with recommendations on effectively implementing the five-year community empowerment development plan to engage homeowners in decision-making processes, fostering a sense of ownership, resilience, and collaboration within the community. These steps lead to the empowerment of homeowners in creating livable and sustainable communities.Item Economically viable and environmnetally safe scale model passenger cargo for cagayan(Don Mariano Marcos Memorial State University -Open University System, 2024) Siares, Jess Avel B.Under PD 474 and RA 9295, MARINA (Maritime Industry Authority) is mandated to provide effective sea linkages between islands and regions in the country. The agency thereby supports the national Government's Nautical Highway Development Program by updating and upgrading the current domestic merchant fleet, establishing new shipping lanes, and encouraging private sector involvement in developing and operating domestic shipping facilities. In this regard, the 10-year Maritime Industry Development Plan (MIDP) was officially launched. Under the program, MARINA has released MARINA Circular No. 2016-02 (MC-2016-02), which is about the phase-out of wooden-hulled ships carrying passengers in domestic shipping. As a Naval Architect, I can propose an economically viable and environmentally safe scale model passenger cargo for Cagayan. This model is an ideal boat concept that can be used for passenger ships to carry Cagayan residents safely and reliably. This research will assist MARINA in choosing the best course of action to forward their modernization initiatives while considering the welfare of the people of Cagayan.Item Healthcare waste management of the la union district hospitals(Don Mariano Marcos Memorial State University -Open University System, 2024) Naguit, Lewellyn U.The study sought to formulate a La Union District Hospital's Healthcare Waste Management Plan.
