ABSTRAK: Inti pokok masalah dalam penelitian ini meliputi latar belakang gerakan sosial masyarakat Kampung Labaluba Desa Kontumere Kecamatan Kabawo Kabupaten Muna, Faktor-faktor yang mendorong gerakan sosial masyarakat Kampung Labaluba Desa Kontumere Kecamatan Kabawo Kabupaten Muna, proses gerakan sosial masyarakat Kampung Labaluba Desa Kontumere Kecamatan Kabawo Kabupaten Muna dan akibat gerakan sosial masyarakat Labaluba Desa Kontumere Kecamatan Kabawo Kabupaten Muna? Latar belakang gerakan sosial masyarakat Kampung Labaluba yaitu keadaan kampungnya yang hanya terdiri dari beberapa kepala keluarga tiap kampung dan jarak yang jauh masing-masing kampung membuat keadaan masyarakatnya sulit untuk berkomnikasi dan tiap kampung hanya terdiri dari lima sampai dengan tujuh kepala keluarga saja. Kampung ini letaknya paling timur pulau Muna terbentang dari ujung kota Raha sekarang sampai kampung Wakuru yang saat ini. Kondisi ini juga yang menjadi salah satu faktor penyebab kampung ini kurang berkembang baik dibidang ekonomi, sosial politik, pendidikan maupun di bidang kebudayaan. Keadaan ini diperparah lagi dengan sifat dan karakter penduduknya yang masih sangat primitif. Faktor yang mendorong adanya gerakan sosial masyarakat Kampung Labaluba Desa Kontumere Kecamatan Kabawo Kabupaten Muna adalah adanya ketidaksesuaian antara keinginan pemerintah setempat dan masyarakat yang mendiami Kampung Labaluba pada waktu itu. Sedangkan proses gerakan sosial masyarakat Kampung Labaluba Desa Kontumere Kecamatan Kabawo Kabupaten Muna bermula ketika pemerintah seolah memaksakan kehendaknya kepada rakyat yang menyebabkan rakyat tidak setuju dengan kebijakan tersebut. Akibat yang ditimbulkan dari adanya gerakan sosial masyarakat Kampung Labaluba Desa Kontumere Kecamatan Kabawo Kabupaten Muna terbagi dua yaitu akibat positif dan akibat negatif.Kata Kunci: Gerakan Sosial, Factor dan Dampaknya ABSTRACT: The main issues in this study include the background of the social movement of Labaluba Village, Kontumere Village, Kabawo Sub-District, Muna District, Factors that encourage social movements of Labaluba Kampung Sub-village, Kontumere Village, Kabawo Sub-District, Muna District, the social movement process of Labaluba Village, Kontumere Village, Kabawo Sub-District Muna Regency and due to Labaluba community social movements Kontumere Village Kabawo District Muna Regency? The background of the Labaluba Kampung community social movement is that the condition of the village consists of only a few heads of households per village and the distance of each village makes it difficult for the community to communicate and each village only consists of five to seven households. This village is located east of the island of Muna stretching from the edge of the city of Raha now to the current village of Wakuru. This condition is also one of the factors causing the village to be less developed in the economic, social political, educational and cultural fields. This situation is made worse by the very primitive nature and character of the population. The factor that motivated the existence of the social movement of Labaluba Village in Kontumere Village, Kabawo Subdistrict, Muna Regency was the mismatch between the wishes of the local government and the people who inhabited Labaluba Village at that time. While the process of social movements in Labaluba Village, Kontumere Village, Kabawo District, Muna Regency began when the government seemed to impose its will on the people, causing the people to disagree with the policy. The consequences arising from the existence of social movements in Labaluba Village, Kontumere Village, Kabawo District, Muna Regency are divided into two, namely positive and negative effects. Keywords: Social Movements, Factors and their Impacts

AbstractThe FtsZ protein is a central component of the bacterial cell division machinery. It polymerizes at mid-cell and recruits more than 30 proteins to assemble into a macromolecular complex to direct cell wall constriction. FtsZ polymers exhibit treadmilling dynamics, driving the processive movement of enzymes that synthesize septal peptidoglycan (sPG). Here, we combine theoretical modelling with single-molecule imaging of live bacterial cells to show that FtsZ’s treadmilling drives the directional movement of sPG enzymes via a Brownian ratchet mechanism. The processivity of the directional movement depends on the binding potential between FtsZ and the sPG enzyme, and on a balance between the enzyme’s diffusion and FtsZ’s treadmilling speed. We propose that this interplay may provide a mechanism to control the spatiotemporal distribution of active sPG enzymes, explaining the distinct roles of FtsZ treadmilling in modulating cell wall constriction rate observed in different bacteria.

AbstractIntermediate filament polypeptides (IFPs) are prominent components of cytoplasmic aggregates, which are pathognomonic for multiple diseases. Recent observations in cultured cells suggest that they are dynamic and subject to regulated turnover. The emerging concept is that multiple factors contribute to motility and turnover of IFP-containing aggregates. To understand their relative contribution, quantitative tools are needed. The current study addresses this need using epithelial cells producing mutant keratin IFPs that have been identified as the cause of the hereditary blister-forming skin disease epidermolysis bullosa simplex. Digital image analysis of individual granules allowed mapping of their complete life cycle, with information on multiple characteristics at any given time-point. The deduced signet features revealed rapid granule fusion and directed transport from the periphery towards the cell centre, and a limited, ~ 30 min lifetime with a slow, continuous growth phase followed by fast disassembly. As paradigmatic proof-of-principle, we demonstrate that inhibition of myosin II selectively reduces granule movement, linking keratin granule motility to retrograde cortical acto-myosin flow. The newly developed methods and established parameters will help in the characterization of known and the identification of novel regulators of IFP-containing aggregates.

The inspection and maintenance of drains with varying heights necessitates a drain mapping robot with trained labour to maintain community hygiene and prevent the spread of diseases. For adapting to level changes and navigating in the narrow confined environments of drains, we developed a self-configurable hybrid robot, named Tarantula-II. The platform is a quadruped robot with hybrid locomotion and the ability to reconfigure to achieve variable height and width. It has four legs, and each leg is made of linear actuators and modular rolling wheel mechanisms with bi-directional movement. The platform has a fuzzy logic system for collision avoidance of the side wall in the drain environment. During level shifting, the platform achieves stability by using the pitch angle as the feedback from the inertial measuring unit (IMU) mounted on the platform. This feedback helps to adjust the accurate height of the platform. In this paper, we describe the detailed mechanical design and system architecture, kinematic models, control architecture, and stability of the platform. We deployed the platform both in a lab setting and in a real-time drain environment to demonstrate the wall collision avoidance, stability, and level shifting capabilities of the platform.

Abstract Background Over the past two decades, various species of forage fish have been successfully implanted with miniaturized acoustic transmitters and subsequently monitored using stationary acoustic receivers. When acoustic receivers are configured in an array, information related to fish direction can potentially be determined, depending upon the number and relative orientation of the acoustic receivers. However, it can be difficult to incorporate directional information into frequentist mark-recapture methods. Here we show how an empirical Bayesian approach can be used to develop a model that incorporates directional movement information into the Arnason-Schwarz modeling framework to describe survival and migration patterns of a Pacific herring (Clupea pallasii) population in coastal Alaska, USA. Methods We acoustic-tagged 326 adult Pacific herring during April 2017 and 2018 while on their spawning grounds in Prince William Sound Alaska, USA. To monitor their movements, stationary acoustic receivers were deployed at strategic locations throughout the Sound. Receivers located at the major entrances to the Gulf of Alaska were arranged in parallel arrays to determine the directional movements of the fish. Informative priors were used to incorporate the directional information recorded at the entrance arrays into the model. Results A seasonal migratory pattern was found at one of Prince William Sound’s major entrances to the Gulf of Alaska. At this entrance, fish tended to enter the Gulf of Alaska during spring and summer after spawning and return to Prince William Sound during the fall and winter. Fish mortality was higher during spring and summer than fall and winter in both Prince William Sound and the Gulf of Alaska. Conclusions An empirical Bayesian modeling approach can be used to extend the Arnason-Schwarz modeling framework to incorporate directional information from acoustic arrays to estimate survival and characterize the timing and direction of migratory movements of forage fish.
