Discretionary Powers in the Context of Legal Regulation of Administrative Procedure
Authors: Luk’yanets Dmytro
Published: December 2023

The article is devoted to the problem consideration of determining the content and characteristics of discretionary powers in the context of the administrative procedure legal regulation, which is caused by the adoption and necessity of introducing the provisions of the Law of Ukraine «On Administrative Procedure» into the practices of the subjects of authority. The actuality of the topic is determined by the necessity to qualify administrative bodies' powers as discretionary and implement the relevant principles of administrative procedure. The article aims to analyze the normative constructions of administrative proceedings available in Ukraine's legislation, which allow for the possibility of exercising discretionary or similar powers to develop a position regarding the limits and features of the practical application of norms of the Law of Ukraine «On Administrative Procedure». Achieving the outlined objective became possible through complex scientific knowledge methods, in particular dialectical and systemic approaches, formal-legal and comparative methods, and methods of analysis and synthesis. It is noted that the vast majority of normatively defined principles of administrative procedure are designed for the implementation of discretionary powers by administrative bodies. It was emphasized that an integral component of discretionary powers, in addition to the availability of legally defined options for decisions that an administrative body can adopt in the presence of specific grounds, is the availability of the administrative body's right to act at its discretion. Based on the conducted research on the content of the administrative bodies' powers in specific types of administrative proceedings, the conclusions were formulated that in administrative proceedings of a registration and permitting nature, the relevant administrative bodies do not have discretionary powers. It is noted that an example of full-fledged discretionary powers is the powers of administrative bodies in tort proceedings. This is due to the fact that sanctions for the commission of relevant offenses have a relatively defined nature. In such cases, the administrative body, at its discretion, selects the type and amount of sanctions, taking into account the circumstances of the case. Unlimited discretion is inherent in the authority of collegial bodies, particularly local self-government bodies, which is determined by the decision-making method by voting of the collegial body members.

Authors: Soloviova Olha
Published: December 2023

December 15, 2023 The Law of Ukraine "On Administrative Procedure" will come into force and introduce new rules for the interaction of the state with individuals (citizens and business) on the basis of the principles of good administration. A similar procedure applies in all member states of the European Union. The value of principles for relations of administrative procedure is primarily manifested in their law enforcement effect. The relevance of the topic is due to the need to ensure the practical implementation of the principles, which allows to comprehend the purpose and content of the administrative procedure, which means to create conditions for the implementation or protection of the rights and interests of the person and direct the administrative body to the conscientious execution of the assigned powers. The article is aimed at studying the new principles of administrative procedure, which for the first time are recognized as starting points for the implementation of their powers by administrative bodies. The achievement of the outlined goal became possible thanks to the use of a set of methods of scientific knowledge, with the help of which the essence of the principles of administrative procedure was determined, the provisions of normative legal acts were analyzed, in order to ensure their practical significance. The work considers such principles as openness, efficiency, presumption of legality of actions and requirements of a person, formality and guarantee of effective remedies. The characteristic of these principles on the basis of scientific approaches in the legal literature is presented and the corresponding provisions of the Law of Ukraine "On Administrative Procedure" on ensuring their practical implementation are analyzed. On the basis of the study, conclusions were formulated regarding the practical significance of the principles of administrative procedure. First, with their help, the administrative body achieves the correct application of material norms of law. Secondly, they provide minimum unified standards for ensuring the implementation and protection of the rights and legitimate interests of participants in administrative proceedings. Third, they interpret individual institutions and rules of administrative procedure. The obtained results of the study can be further used to assess the legality of the adopted administrative acts, procedural decisions and the performed procedural actions.

Published: December 2023

Parkinson's disease is the most common nervous system disease that affects all ethnicities, genders, and ages, with a higher prevalence in the elderly and men. Developing countries tend to have higher cases of Parkinson's. The prevalence of death due to Parkinson's in Indonesia reaches the fifth highest cases in Asia and 12th in the world. This neurodegenerative disease affects a person's ability to control movement. Currently, the diagnosis of Parkinson's disease is only based on observation of motor symptoms. Therefore, early detection of the disease cannot be done. His paper proposes an efficient way to detect Parkinson's disease symptoms by comparing the fundamental frequencies of patients' voices using the random forest method. Random forest is a Machine Learning method that applies the ensemble concept, which aims to improve the performance of the classification by combining several decision trees as a basis. Random forests have shown superior algorithm performance in numerous health studies. In this study, the dataset consisted of 20 patients with Parkinson's and 20 normal patients. Data for each patient was taken from 26 types of voice records, and thus, the total data was 1,040 observations. The obtained data is prepared by filtering and rescaling. Then, the data is split and modelled using the Random Forest Method. The random forest model obtained accuracy results of 72.50%, precision (normal) of 72.28%, precision (Parkinson's) of 72.73%, sensitivity (normal) of 73.00%, sensitivity (Parkinson's) of 72.00% and AUC is 80.70%. The built random forest model is quite good at Parkinson's disease detection.

Over time, energy needs will continue to increase. Dependence on the use of fossil energy results in the availability of such energy will run out at any time, so it is necessary to develop research on geothermal energy that is environmentally friendly and renewable. One of the Geothermal Work areas is on Mount Lawu, located at coordinates between 111°15' east longitude and 7°30' south latitude in several districts Central Java Province and East Java Province. The purpose of this study is to provide information related to geothermal potential using the gravity method by knowing the temperature of the area and the 3D modeling of subsurface structures. Based on the results of the Second Vertical Derivative (SVD) analysis, three normal faults were found in geothermal sources. The modeling results show that the residual anomaly map depicts a distribution of high anomalies ranging between 2 mGal up to 6.5 mGal scattered from North to South and East to West, suspected to be caused by lava rock intrusion. The results of the 3D inversion model show there are three layers, namely clay rock, which is suspected to be cap rock at a depth of 500 - 2500 m, pyroclastic lava rock, which is suspected to be as a reservoir at a depth of 3000 - 4500 m, and lava, which is suspected to be as a reservoir heat source at a depth of 5000 - 8000 m. Based on the map in Land Surface Temperature (LST) obtained the temperature value of Mount Lawu ranging from 3.14 °C - to 23.25 °C.

Published: December 2023

Actinomycetes form associations with plants through colonizing plant tissues (endophytes) or by residing in the soil around some plants' roots (rhizosphere). Actinomycetes are known to produce antibacterial compounds. This study aimed to investigate the antibacterial activity of actinomycetes associated with the clove plant (Syzygium aromaticum) against Staphylococcus aureus and Escherichia coli. Actinomycetes were isolated from clove plants and the rhizosphere, and their antimicrobial activity against Staphylococcus aureus and Escherichia coli was evaluated using the agar plug method, where the presence of transparent zones around 10-day-old actinomycete growth indicated inhibition of bacterial growth. Four isolates showed inhibitory effects against Staphylococcus aureus, while only three isolates, B.4, T.3, and T.4, demonstrated inhibitory activity against Escherichia coli, as indicated by the presence of inhibition zones. Isolate T.3 exhibited the highest inhibition zone of 8.5 mm against S. aureus, whereas B.4 displayed the highest inhibition zone of 7.7 mm against E. coli. In conclusion, the actinomycetes found in clove plants (Syzygium aromaticum) demonstrate antibacterial properties against Staphylococcus aureus and Escherichia coli, indicating their potential as antibacterial agents.

Published: December 2023

Water quality problems that are often encountered, especially by-product wastewater resulting from industrial processes that do not meet the requirements for wastewater quality standards. Iron levels in wastewater can cause the water to turn brownish yellow and produce an unpleasant odor, which of course has a big impact on the environment. Therefore, it is necessary to implement a treatment process to reduce the iron level in the water, ensuring that the water is safe when discharged into the environment. The purpose of this research is to analyze the initial parameters of temperature, pH, TDS, TSS, dissolved oxygen (DO) and dissolved iron (Fe2+) in industrial waste water and then wanted to know whether the venture injector type micro bubble aeration process was able to increase the value of dissolved oxygen (DO) and decrease the dissolved iron content (Fe2+) in wastewater and to know the micro bubble type aeration process Venture injectors are the best to use. The research was conducted with an experimental design using a completely randomized design (RAL) with two factors: air flow (2 LPM, 4 LPM, and 6 LPM) and aeration time (0 minutes, 15 minutes, 30 minutes, 45 minutes, and 60 minutes), each with two repetitions. In the results of the initial parameter analysis, the pH value was 8.02 (alkaline), the temperature value was 28°C, the TDS value was 1548.3 mg/L, the TSS value was 291 mg/L, the DO value was 0.1 mg/L and dissolved iron (Fe2+) of 7.453 mg/L. After conducting research, it was found that the venture injector type micro bubble aeration process was able to increase the value of dissolved oxygen (DO) and reduce dissolved iron (Fe2+) in industrial waste water, the best increase in dissolved oxygen (DO) at 6 LPM air flow for 60 minutes was able to increase oxygen dissolved (DO) to 2.40 mg/L. The most efficient and effective reduction in the value of dissolved iron (Fe2+) at 6 LPM air flow with a time of 15 minutes was able to reduce the value of dissolved iron by 84.42%.

Authors: Teixeira Vitor Hugo
Published: December 2023

Enquanto a cognição compreende os processos mentais inconscientes, a metacognição é a consciência e gestão desses processos pelo indivíduo. Sua importância para a Ciência da Informação (CI) reside no fato de que seus benefícios alcançam tanto usuários/as quanto profissionais da informação em suas atividades distintas. Apesar do cenário favorável para aplicação desse construto no âmbito dessa ciência, verificou-se que são incipientes os estudos que abordam tal relação. Com isso, surgiu o questionamento: Como a CI tem se apropriado da metacognição em seus estudos? Assim, o artigo possui o objetivo de discutir como a metacognição está presente na pesquisa em CI no Brasil a partir da incidência do tema nos periódicos científicos da área. Metodologicamente, trata-se de uma pesquisa básica, descritiva e qualiquantitativa. Como procedimento técnico, foi realizada uma pesquisa documental a partir da Base de Dados Referenciais de Artigos de Periódicos em Ciência da Informação (Brapci). Constituindo um corpus de apenas dez artigos, os resultados apontam que a relação entre a metacognição e a CI é delineada por contribuições cujos principais aspectos envolvem: tomada de decisão; estratégias de busca; avaliação de fontes; aprendizado e retenção da informação; e uso eficaz da informação. Conclui-se que a metacognição constitui uma abordagem essencial para entender como usuários/as e profissionais interagem com a informação e, assim, aprimorar os serviços e sistemas de informação para atender às suas necessidades de maneira mais eficaz, justificando a indispensabilidade de maiores investimentos para a sua aplicação teórica e prática no contexto dos ambientes informacionais.

Published: December 2023

Metabolic syndrome (MetS) therapy with phytochemicals is an emerging field of study with therapeutic
potential. Obesity, insulin resistance, high blood pressure, and abnormal lipid profiles are all components
of metabolic syndrome, which is a major public health concern across the world. New research highlights
the promise of phytochemicals found in foods, including fruits, vegetables, herbs, and spices, as a sustainable
and innovative method of treating this illness. Anti-inflammatory, antioxidant, and insulin-sensitizing
qualities are just a few of the many positive impacts shown by bioactive substances. Collectively, they alleviate
the hallmark symptoms of metabolic syndrome by modulating critical metabolic pathways, boosting insulin
sensitivity, decreasing oxidative stress, and calming chronic low-grade inflammation. In addition, phytochemicals
provide a multimodal strategy by targeting not only adipose tissue but also the liver, skeletal muscle,
and vascular endothelium, all of which have a role in the pathogenesis of MetS. Increasing evidence
suggests that these natural chemicals may be useful in controlling metabolic syndrome as a complementary
treatment to standard medication or lifestyle changes. This review article emphasizes the therapeutic potential
of phytochemicals, illuminating their varied modes of action and their ability to alleviate the interconnected
causes of metabolic syndrome. Phytochemical-based interventions show promise as a novel and sustainable approach
to combating the rising global burden of metabolic syndrome, with the ultimate goal of bettering public
health and quality of life.

Published: December 2023

Biological resource centres (BRCs) are an essential part of the infrastructure underpinning life sciences and biotechnology. They consist of service providers and repositories of the living cells, genomes of organisms, and information related to heredity and the functions of biological systems. The growing worldwide demand for biological resources provides good reasons for greatly increasing the number and quality of BRCs. BRCs provide essential expertise for the formulation of government policies on biological resources and for information and assurance to the public. The establishment of national BRCs can help identify and address existing gaps and take advantage of opportunities not currently met by existing ex-situ collections. They can then improve the quality of services offered and achieve efficiencies and cost savings. A global BRC network would connect national BRCs and provide the framework within which co-ordination, harmonisation and quality assurance could be provided. BRCs need to provide greater quality assurance than is currently ensured by collections and databases.
Biotechnological Importance of Exosomes
Authors: Bakar Elvan , Erim Zeynep , Pelin Türker Nebiye
Published: December 2023

Extracellular vesicles are molecules secreted by cells, wrapped in
phospholipids and carrying some types of RNA, DNA and protein in their inner region.
Extracellular vesicles are classified as apoptotic bodies, microvesicles, and exosomes
based on their extent and formation process. Exosomes, which have the smallest
structure, have received more attention than other extracellular vesicles. Exosomes
contain different types of molecules in their structures. Cell membranes comprise a
lipid bilayer and contain different cargo molecules and different surface receptors,
depending on the cells of origin where biogenesis takes place. The biogenesis of
exosomes begins within the endosomal system. Then they mature and are released out
of the cell. The biogenesis of exosomes may be associated with the ESCRT complex
and may depend on many molecules other than the ESCRT complex. Exosomes
excreted by the origin cells are taken up by the target cells in different ways and show
their effects. The effects of exosomes on their target cells may vary according to the
cargo molecules they carry. They participate in cell-to-cell communication by sending
different signals to distant or nearby target cells. Exosomes have a variety of
pathological and physiological effects on disease and health. They have different
effects on many diseases, especially cancer. They play an active role in cancer
development, tumor microenvironment, angiogenesis, drug resistance and immune
system. There are many diseases that can be used as a biomarker due to increased
secretion from cells of origin in pathological conditions. In addition, exosomes can be
utilized as drug transportation systems due to their natural structure. In addition, they
are potential candidates as effective vaccines because of their effects on immune
system cells or the effects of exosomes secreted from immune system cells.

Published: December 2023

A tumor consists of not only cancer cells but also an ecosystem including
different subpopulations. Cancer stem cells (CSCs) are a rare subpopulation in the
tumor cell population. Traditional therapies, such as chemotherapy and radiotherapy
target cancer cells except for CSCs. Therefore, the self-renewal and colony formation
capacity of CSCs provides the recurrence of tumors as well as drug resistance.
Different strategies are used to eradicate CSCs with the knowledge of CSC properties.
The recent technologic revolution gives a chance to design nanoscale medicines for the
effective treatment of CSCs. Nanoparticle-based delivery systems improve the
transport of traditional therapeutic drugs across biological barriers with maximum
bioavailability, less toxicity, and side effects, and take advantage in combination with
specific CSC targets, controlled and site-specific release. This chapter summarizes the
current models of CSCs, the molecular mechanisms leading to metastases and drug
resistance of CSCs, strategies to target CSCs, examples of currently approved
nanomedicine drugs and future perspectives.

Published: December 2023

The safety and efficacy of each drug candidate, including nanomedicine
considered for pharmaceutical use, primarily must be determined in vitro. In this
context, the most widely used method is cytotoxicity tests, which include cell culture
studies. It examines the parameters of membrane integrity, metabolite incorporation,
structural alteration, survival and growth in tissue culture, enzyme assays, and the
capacity for transplantation within the scope of viability tests. Within the scope of cell
culture studies, tests related to apoptosis, which are effective in proper cell cycle,
immune system and embryonic development, are also included. Another way to detect
cell viability is to detect the biomolecules it expresses. Determination of protein
expression is one of the preferred methods in this sense. Within the scope of this
chapter, there is information about cell culture-based methods under these main
subjects, which are applied to nanomedicines.

Laparoscopic instruments should be sterilized by high-level disinfection
(H.L.D.). Sterilization is any process that removes or kills all microbial organisms,
such as fungi, bacteria, viruses, spore forms, etc., present on a surface, contained in a
fluid, or a compound such as biological culture media. Sterilization can be achieved by
applying heat, chemicals, and irradiation; high-pressure sterilization is a process that
destroys or eliminates all forms of microorganisms. Disinfection is a process that
eliminates many or all pathogenic microorganisms, except bacterial spores, on
inanimate objects. Decontamination is the removal of all pathogenic microorganisms
from objects to make them safe to handle / use/ discard.

Optical devices in laparoscopic surgery comprised a telescope (0-30-45
degree telescopes), a light source, a light cable, a camera, and a monitor. All play an
essential role from the beginning to the end of the procedure. The outcome of a suitable
laparoscopic procedure depends on optical devices. The telescope used may have 0-3-45 degree view. The light source can be Helium or xenon. Xenon is costly but
resembles natural light more, giving a good in vivo view.

Optical fibers carry light into the abdomen, and the rod lens mechanism moves images
to the camera and then to monitor, to result in a successful procedure.

This chapter will go through the mechanism and working of light cables, cameras and
light sources used in laparoscopy

Operative hand instruments play a pivotal role in Laparoscopic surgeries.
They are either disposable or reusable. Most instruments are made up of three parts
mainly; Handle, Outer covering sheath and working insert. Instruments are broadly
categorized based on the type of dissection they are used for. Instruments for Blunt
dissection are Graspers and dissectors. Graspers can be of traumatic or atraumatic
variety. Bipolar and Maryland are the two essential dissectors used widely. Instruments
used for sharp dissection are scissors, knives, needle holders, coagulation devices,
electrosurgery hooks and a spatula. All the reusable instruments have to be sterilized
before each use. A few instruments have to be dissembled before sterilizing. Hence,
basic knowledge regarding the various instruments is vital for a laparoscopic surgeon
to operate flawlessly

Published: December 2023

Early endoscope was developed about 50 years ago. It was initially
developed as a diagnostic tool. Since then, several modifications in endoscopes have
been made with many developments in endoscopic accessories. In the current era,
endoscopy is used for both diagnostic and therapeutic procedures. Endoscopic
accessories are essential tools for therapeutic endoscopic procedures. Endoscopic
accessories are specially designed devices that pass through accessory channel of the
endoscope & therapeutic endoscopic procedures. Routinely encountered endoscopic
endoscopy needs commonly available endoscopic accessories. Common clinical
problems in day to day practice are gastrointestinal tract bleeding, gastrointestinal tract
foreign bodies, gastrointestinal tract strictures and the requirement of enteral access for
enteral feeding. These procedures can be carried out in a day-to-day practice after
gaining adequate experience and knowledge about the procedures. Commonly used
endoscopic accessories can be divided into hemostatic devices, foreign Body (FB)
removal devices, feeding tubes, biopsy forceps and dilators. Hemostatic devices are
endoscopic accessories to control bleeding from the GI tract. Bleeding from the GI
tract may be of variceal or non-variceal origin and accordingly different devices may
be required. Various types of foreign body ingested can be encountered during clinical
practice which can be dealt with different endoscopic accessories. Enteral feeding is a
safe, effective and physiological means of providing enteral nutrition. Depending on
the clinical situation, gastric or naso-jejunal enteral access may be required for enteral
nutrition. Feeding tubes can be placed endoscopically for enteral access. Different
types of feeding tubes are available. Biopsy forceps are tissue acquisition devices for
diagnostic purposes. 
Primary Mucosa-Associated Lymphoid Tissue (MALT) Lymphoma of the Prostate: MRI and FDG-PET Imaging Findings
Authors: Hama Yukihiro
Published: December 2023

Background: Primary mucosa-associated lymphoid tissue (MALT) lymphoma of the prostate is a rare condition, and there is no report on magnetic resonance imaging (MRI) and its relationship with fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET). Objectives: The purpose of this article is to present the MRI and FDG-PET imaging findings of primary MALT lymphoma of the prostate and discuss the imaging findings’ importance in the diagnosis and management. Case summaries: A 73-year-old male patient underwent a prostate biopsy for lower urinary tract symptoms and an elevated serum prostate-specific antigen level. Histopathologic and immunohistochemical findings were consistent with MALT lymphoma. As the tumor was confined to the prostate and adjacent tissues and no lymph node metastases were detected on PET-CT, the diagnosis was primary MALT lymphoma of the prostate. The tumor of the transitional zone infiltrated along the obturator internus muscle and into the pubic bone, the levator ani muscle was almost intact on MRI. Conclusion: The absence of lymph node metastasis or gross muscle destruction but a high degree of invasiveness into surrounding tissues is an important imaging finding in the diagnosis of primary MALT lymphoma of the prostate.

Published: December 2023

Plastic waste accrual in the environment has been identified as the topmost significant global issue related to modern civilization. Traditional waste disposal methods, such as open burning, landfilling, and incineration, have increased greenhouse gas emissions in economic and material losses. Unless immediate action is made to curtail demand, prolong product lifespans, enhance waste management, and encourage recyclability, plastic pollution will increase due to an almost threefold increase in plastic use spurred by growing populations and affluence. Plastic production primarily is from crude oil or gas despite more than a fourfold growth from ~6.8 million tonnes in 2000 to ~30 million tonnes in 2019; only ~6% of the world’s total plastics production is made from recycled plastics. The competitiveness and profitability of secondary markets may increase with the establishment of recycled content objectives and advancements in recycling technology. In this review, emerging approaches and the creation of value-added materials from waste plastics such as carbon nanotubes and other carbonaceous nanomaterials production, the environmental impacts of plastic waste, African status concerning plastic waste, the importance of modern techniques in plastic waste management, and the circular economy impact on plastic waste utilization are the high points of this study.

Vận dụng mô hình dự báo này cho kết quả với độ chính xác cao, gần đúng với sản lượng xuất khẩu thực tế. Ngoài ra, nghiên cứu này cũng đề xuất một số khuyến nghị đối với các nhà hoạch định chính sách xuất khẩu. Cụ thể là các nhà hoạch định cần chú trọng đa dạng hoá thị trường xuất khẩu, khai thác hiệu quả cơ hội từ các FTA, quy hoạch vùng nuôi thủy sản hợp lý, điều tiết sản lượng bột cá xuất khẩu tránh sự thiếu hụt trong nước, tạo sự nghịch lý khi phải nhập khẩu bột cá từ các nước với số lượng lớn.

Published: December 2023

Theoretical and empirical evidence suggests that organizational justice impacts organizational cynicism, but the influence of its various dimensions is inconsistent. This inconsistency necessitates the introduction of moderating variables for a more comprehensive understanding. In this context, hope is selected as a moderating variable due to its ability to mitigate the adverse effects of organizational cynicism. The objective of this study is to explore how distributive, procedural, and interactional justice affect organizational cynicism, with hope serving as a moderating factor. The research adopts an explanatory correlational design. Participants include 126 employees from the Mojokerto State Police School (SPN), selected through census sampling. The study utilizes scales for measuring organizational cynicism, organizational justice, and hope. Data is analyzed using moderated regression analysis (MRA). The findings reveal that distributive and interactional justice negatively impact organizational cynicism. Moreover, hope moderates the relationship between procedural justice and organizational cynicism, as well as the impact of interactional justice on cynicism. Significantly, hope moderates the effects of distributive, procedural, and interactional justice on organizational cynicism, underscoring its role in enhancing the impact of these justice dimensions on cynicism. This research contributes to a nuanced understanding of the interplay between organizational justice and cynicism, highlighting the critical role of hope as a moderator.

Published: December 2023

Recent studies have noted a rising prevalence of common mental health issues, including suicidal ideation and self-harming behaviors, among college students globally. However, limited attention has been given to the preparedness of educational institutions in addressing these concerns. This study aims to comprehensively assess the landscape of mental health support within Indonesian universities, with a particular focus on uncovering the availability of policies and training as well as faculty members’ perceptions of students’ mental health challenges, the identification of responsible parties for providing assistance, and the specific support needs of faculty members prior to the pandemic. Employing a mixed exploratory method, the research engaged 172 faculty members from 72 universities in Indonesia who completed an online survey. The quantitative data underwent descriptive analysis, while the free-text responses were thematically categorized. The findings revealed that (1) most universities still lack formal policies on dealing with students in psychological distress; (2) there is a gap between faculty members’ willingness to discuss students’ mental health and their decision to refer students to mental health services; and (3) there is a necessity for building a multi-layered support system for this issue. Hence, universities are advised to proactively institute formal policies to address students in psychological distress, implement comprehensive mental health training for both students and faculty, and enhance the accessibility of professional psychological support services, thereby creating a robust framework for promoting and safeguarding the mental well-being of students.

The Armed Forces of the Philippines (AFP) currently is facing a challenge in its fiscal budget due to the significant percentage of the allocation going to the pension of retired military personnel and the figure continues to grow due to the automatic indexation system. However, the service of retired soldiers should not be set aside considering the time they have spent for the service to the country. There have been related studies conducted to help with this problem and help the AFP obtain funds that can support its budget needs. One of which is the leasing of its vast lands and converting it to higher economic purposes and several moves by the AFP leadership have been made to start with this effort. The previous experience related to this kind of scheme was done through the Bases Conversion and Development Authority (BCDA). This however includes the leasing and sale of defense land specifically identified under the law. The leasing and sale of defense real estate under the management of BCDA are located within the proximity of urban areas like FBGC, Subic, and Clark which in the case of other military lands cannot follow a similar land use due to their location. Conversion of military base lands for higher economic purposes can however take a different turn by converting them as industrial sites and with that the researchers see fit the erection of solar power plants, especially in the Fort Magsaysay Military Reservation which is by far the largest military reservation the AFP now has. Based on research, the Fort Magsaysay Military Reservation is within the area with the highest solar radiation as compared to other areas tested. Besides that, with the current thrust of the government to increase the contribution of green energy to the energy mix of the country, this is an opportunity for the AFP to open such possibilities of using military lands for higher economic purposes as a source of additional funding.
