Tahap pencapaian pelaksanaan Program Kebun Komuniti oleh pihak berkuasa tempatan

Persaingan guna tanah di dalam bandar telah menyekat aktiviti pertanian untuk dibangunkan dan secara tidak langsung masyarakat di bandar perlu bergantung kepada sumber makanan atau produk pertanian dari kawasan luar bandar. Namun begitu, kewujudan tanah-tanah terbiar termasuk di kawasan bandar adalah amat membimbangkan. Program Kebun Komuniti adalah salah satu konsep di bawah Program pertanian Bandar yang amat popular di kebanyakan negara pada masa kini termasuk di Malaysia. Oleh itu, matlamat kajian ini adalah supaya terdapat satu garis panduan yang menyeluruh dan standard berkaitan pelaksanaan Program Kebun Komuniti kepada semua PBT sebagai satu program yang dapat memberi manfaat kepada komuniti melalui aktiviti bercucuk tanam, meningkatkan imej bandar melalui pengurusan ruang-ruang kosong dan terbiar dan ke arah pemeliharaan alam sekitar yang lestari. Ke arah itu, objektif kajian ini adalah untuk mengenal pasti kaedah pelaksanaan Program Kebun Komuniti oleh Pihak Berkuasa Tempatan dan mengkaji tahap pencapaian pelaksanaan Program Kebun Komuniti dari perspektif komuniti. Pengkaji telah memilih kawasan pentadbiran Majlis Bandaraya Shah Alam (MBSA) sebagai kajian kes kerana mempunyai penglibatan aktif dalam pelaksanaan Kebun Komuniti sejak tahun 2014. Kajian ini dilaksanakan secara kualitiatif di mana data primer diperoleh menerusi temu bual semi struktur melibatkan 16 Pengerusi Kebun Komuniti dan dua pegawai daripada MBSA yang terlibat secara langsung dalam Pelaksanaan Program Kebun Komuniti. Selanjutnya, analisa deskriptif dilaksanakan terhadap dapatan temu bual tersebut. Berdasarkan penemuan kajian, pelaksanaan Program Kebun Komuniti oleh MBSA ini berjaya mencapai objektif dan matlamat asal penubuhannya seperti mengurangkan kawasan terbiar, mengurangkan kos perbelanjaan harian, menggalakkan interaksi sosial dan meningkatkan amalan kitar semula. Namun, terdapat dua matlamat tidak dapat dicapai iaitu dari segi meningkatkan penglibatan belia dalam aktiviti pertanian dan menambahkan pendapatan melalui jualan hasil. Berdasarkan penemuan tersebut, beberapa cadangan dikemukakan dan diharapkan kajian ini dapat membantu memberi input yang bermanfaat kepada semua pihak yang terlibat dalam membangunkan polisi Program Kebun Komuniti yang holistik dan efisyen pada masa hadapan

RIS-aided Multi-hop Backhauling for 5G/6G UAV-assisted Access Points, Journal of Telecommunications and Information Technology, 2023, nr 2

Drones are considered to be an important part of future 6G telecommunication systems. Thanks to their quick deployment potential, they provide additional connectivity options in the form of a flying hotspot. However, in such use cases, they typically require a wireless backhaul link to facilitate their proper operation, which might be a challenging task in dense urban environments. One of the potential methods that may be relied upon to connect such nodes is the integrated access and backhaul (IAB) approach, where part of the spectrum allocated to users accessing the base station is used for wireless backhauling. Thus, in this work, we consider the problem of establishing a multi-hop wireless backhaul link following the IAB concept, with the aid of drone relay stations (DRSs) and reconfigurable intelligent surfaces (RISs). We formulate the problem of coverage improvement with a fixed number of relays, assuming certain throughput requirements for the backhaul link. The simulations show that the use of RISs offers a coverage improvement in such a scenario or a reduction in the number of nodes involved in ensuring the required backhaul performance

Autophagy Regulation of the Tumor Immunity – An Old Machinery for a New Function

Cancer was initially thought to be just a disease of cells with deregulated gene expression. It may be more accurate to consider cancer as a disease of the microenvironment. Despite the remarkable and fairly rapid progress over the past two decades regarding the role of the microenvironment in cancer biology and treatment, our understanding of its actual contribution to cancer resistance is still poor and fragmented. Nevertheless, the microenvironment is now considered to be of critical importance during the initiation and progression of carcinogenesis since it is involved in shaping and remodeling stroma reactivity and in reprogramming phenotypic and functional plasticity. Therefore, the tumor microenvironment represents an important hallmark of cancer, and the challenge now is to better understand how the tumor microenvironment participates in the emergence of immune-resistant tumor cell variants, which appears to be the greatest impediment to successful immunotherapy. In this context, autophagy has recently emerged as a new player in regulating the antitumor immune response under hostile tumor microenvironment. In this review, we will summarize recent data describing how autophagy activation under hypoxic stress impairs the antitumor immune response. In addition, we will discuss how tumor manages to hide from the immune attack and either mounts a “counterattack” or develops resistance to immune cells. In particular, we will focus on the effect of hypoxia-induced autophagy in allowing tumor cells to outmaneuver an effective immune response and escape from immunosurveillance. It is our belief that autophagy may represent a conceptual realm for new immunotherapeutic strategies aiming to block immune escape and therefore providing rational approach to future tumor immunotherapy design

The Critical Role of Hypoxia in Tumor-Mediated Immunosuppression

Underestimated for a long time, the involvement of the microenvironment has been proven essential for a better understanding of the cancer development. In keeping with this, the tumor is not considered anymore as a mass of malignant cells, but rather as an organ composed of various malignant and nonmalignant cell populations interacting with each other to create the tumor microenvironment. The tumor immune contexture plays a critical role in shaping the tumor immune response, and it is now well supported that such an immune response is impacted by the hypoxic stress within the tumor microenvironment. Tumor hypoxia is closely linked to tumor progression, metastasis, treatment failure, and escape from immune surveillance. Thus, hypoxia seems to be a key factor involved in creating an immune-suppressive tumor by multiple overlapping mechanisms, including the impairment of the function of cytotoxic immune cells, increasing the immunosuppressive properties of immunosuppressive cells, and activating resistance mechanism in the tumor cells. In this chapter, we review some recent findings describing how hypoxic stress in the tumor microenvironment hijacks the antitumor immune response

EGF controls the in vivo developmental potential of a mammary epithelial cell line possessing progenitor properties

The bilayered mammary epithelium comprises a luminal layer of secretory cells and a basal layer of myoepithelial cells. Numerous data suggest the existence of self-renewing, pluripotent mammary stem cells; however, their molecular characteristics and differentiation pathways are largely unknown. BC44 mammary epithelial cells in culture, display phenotypic characteristics of basal epithelium, i.e., express basal cytokeratins 5 and 14 and P-cadherin, but no smooth muscle markers. In vivo, after injection into the cleared mammary fat pad, these cells gave rise to bilayered, hollow, alveolus-like structures comprising basal cells expressing cytokeratin 5 and luminal cells positive for cytokeratin 8 and secreting β-casein in a polarized manner into the lumen. The persistent stimulation of EGF receptor signaling pathway in BC44 cells in culture resulted in the loss of the in vivo morphogenetic potential and led to the induction of active MMP2, thereby triggering cell scattering and motility on laminin 5. These data (a) suggest that BC44 cells are capable of asymmetric division for self-renewal and the generation of a differentiated progeny restricted to the luminal lineage; (b) clarify the function of EGF in the control of the BC44 cell phenotypic plasticity; and (c) suggest a role for this phenomenon in the mammary gland development
