Preparedness of Local Government Units on Full Devolution with the Implementation of the Mandanasgarcia Ruling

This study assessed the preparedness of cities and municipalities in Region III for the full devolution of basic services in alignment with the Mandanas-Garcia Ruling by the Year 2022, following the enactment of RA 7160 (1991 Local Government Code). Utilizing descriptive and comparative research methods, the investigation revealed that a considerable proportion of LGU departments consist of small teams, indicative of prevalent smaller organizational units. LGUs demonstrated a moderate level of preparedness, with employees perceiving higher readiness in transition planning compared to local executives and department heads. Notably, local executives consistently felt more prepared in financial planning, human resources, and facilities management. Significant differences in preparedness levels were identified across LGUs concerning transition planning, coordination, financial management, human resources, and facilities and equipment, with p-values below the 0.05 significance threshold. Challenges in full devolution, including funding, manpower, coordination, revenue generation, and procurement, were highlighted, exacerbated by pandemic-related issues and urban development discrepancies. Proposed solutions encompass strategies to enhance local revenue, improve personnel recruitment, invest in capacitybuilding, foster collaboration, and advocate for standardized policies. This study contributes valuable insights into the nuanced landscape of LGU preparedness for devolution, paving the way for targeted interventions and policy recommendations.

A model of ocular ambient irradiance at any head orientation

Exposure to ambient ultraviolet radiation is associated with various ocular pathologies. Estimating the irradiance received by the eyes is therefore essential from a preventive perspective and to study the relationship between light exposure and eye diseases. However, measuring ambient irradiance on the ocular surface is challenging. Current methods are either approximations or rely on simplified setups. Additionally, factors like head rotation further complicate measurements for prolonged exposures. This study proposes a novel numerical approach to address this issue by developing an analytical model for calculating irradiance received by the eye and surrounding ocular area. The model takes into account local ambient irradiance, sun position, and head orientation. It offers a versatile and cost-effective means of calculating ocular irradiance, adaptable to diverse scenarios, and serves both as a predictive tool and as a way to compute correction factors, such as the fraction of diffuse irradiance received by the eyes. Furthermore, it can be tailored for prolonged durations, facilitating the calculation of radiant dose obtained during extended exposures.

Interpretability analysis in transformers based on attention visualization

Self-attention is the core idea of the transformer, a kind of special structure for models to understand sentences and texts. Transformer is growing fast, but the model's internal unknowns are still out of control. In this work, the research visualizes self-attention and observes those self-attentions in some transformers. Through observation, there are five types of self-attention connections. The research classifies them as Parallel self-attention head, Radioactive self-attention head, Homogeneous self-attention head, X-type self-attention head, and Compound self-attention head. The Parallel self-attention head is the most important. The combination of different types will affect the performance of the transformer. Visualizations can indicate the location of different types. The results show that some homogeneous heads should be more varied in that case the model will perform better. A new training method is called local head training method, and the local training method may be useful during training transformer. The purpose of this study is to lay the foundation for model biology, to take other perspectives to understand transformers, and to fine-tune training methods.

The Etiology of Neuromuscular Hip Dysplasia and Implications for Management: A Narrative Review.

This study summarizes the current knowledge of the etiology of hip dysplasia in children with neuromuscular disease and the implications for management. This article is based on a review of development of the hip joint from embryology through childhood growth. This knowledge is then applied to selective case reviews to show how the understanding of these developmental principles can be used to plan specific treatments. The development of the hip joint is controlled by genetic shape determination, but the final adult shape is heavily dependent on the mechanical environment experienced by the hip joint during growth and development. Children with neuromuscular conditions show a high incidence of coxa valga, hip dysplasia, and subluxation. The etiology of hip pathology is influenced by factors including functional status, muscular tone, motor control, child's age, and muscle strength. These factors in combination influence the development of high neck-shaft angle and acetabular dysplasia in many children. The hip joint reaction force (HJRF) direction and magnitude determine the location of the femoral head in the acetabulum, the acetabular development, and the shape of the femoral neck. The full range of motion is required to develop a round femoral head. Persistent abnormal direction and/or magnitude of HJRF related to the muscular tone can lead to a deformed femoral head and a dysplastic acetabulum. Predominating thigh position is the primary cause defining the direction of the HJRF, leading to subluxation in nonambulatory children. The magnitude and direction of the HJRF determine the acetabular shape. The age of the child when these pathomechanics occur acts as a factor increasing the risk of hip subluxation. Understanding the risk factors leading to hip pathology can help to define principles for the management of neurologic hip impairment. The type of neurologic impairment as defined by functional severity assessed by Gross Motor Function Classification System and muscle tone can help to predict the risk of hip joint deformity. A good understanding of the biomechanical mechanisms can be valuable for treatment planning.

PT Bukit Asam Dermaga Kertapati Unit (PTBA Derti) is a State-Owned Enterprise (BUMN) in the coal mining business. As a coal distribution firm, PT Bukit Asam Unit Dermaga Kertapati is required to practice Corporate Social Innovation (CSI) and environmental social responsibility in the area surrounding its activities. The PTBA Derti CSI program is carried out in Sukamoro Village under the name "LENTERA Sukamoro". It focuses on community development that is commensurate with the community's social, economic, and environmental situations. This study aims to investigate, from the viewpoint of program participants, the results of a corporate social innovation (CSI) initiative in community development. Data was gathered through surveys, questionnaires, and in-depth interviews with 15 LENTERA Sukamoro program participants, PT Bukit Asam Dermaga Kertapati, and local government heads and officials. The study discovered that the "LENTERA Sukamoro" program from PTBA Derti was able to solve a variety of difficulties in Sukamoro Village, including a large number of housewives who do not have jobs or engage in productive activities, poverty, a lack of skills, and unproductive land issues. The "LENTERA Sukamoro" program enables the community to enhance its skills and capacities, raise income and welfare, and gain access to renewable energy. This study adds to the limited literature on CSI in Indonesia by examining how commercial organizations in the country contribute to community development through CSI. This study's findings should be valuable to community development practitioners, CSI providers, and researchers.

지방자치단체장의 정치성향별 지방자치단체 슬로건 변화에 관한 연구

This study is an analytical study on the changes of slogans of local governments. This study aims to confirm that whether the local slogans advocated by local governments can be influenced by the political inclinations of elected leaders. The scope of the study is local governments where the head of a local government was replaced by a different political party. Core vocabulary was derived from the frequency of words used in slogans and analyzed the values pursued and images emphasized by political orientation. Through comparative research, It was discovered that not only did the content of slogans change depending on the political leanings of the local government head, but also the design form of the slogans also changed. It was found that blue is often used in the slogans of local governments where progressive leaders had been in office, while local governments where conservative heads of organizations are elected often replace slogans using red. On the other hand, through an investigation of the words emphasized in their slogans, it was found that the common goal of local governments, transcending the trends of the times and political stances, is the happiness of local residents. It was confirmed that there is a need to improve the problem of the short life span of local government slogans due to the use of colors and word selection that show similarities with national administration, and to create and manage a viable slogan that can blend harmoniously into the overall city brand and meet the basic goals of regional development and the satisfaction of local residents.

Study on the lower head failure in severe accidents Part II: Thermal-mechanical coupling behavior analysis on CAP1400 reactor lower head

Under severe accident conditions with core meltdown, large amounts of molten material relocate to the lower head at high temperatures. Significant thermal and mechanical loads may lead to failure of the reactor pressure vessel (RPV) lower head, spreading radioactive fission products. Lower head failure time and location are crucial for accident mitigation and consequence assessment. This study developed a thermodynamic failure analysis model for the lower head by investigating material failure mechanisms, coupling this into an Integrated Severe Accident Analysis code (ISAA), and conducting experimental validation and applied research. Part I mainly introduces the thermodynamic analysis module development, validation against OLHF experiments, and preliminary failure criteria analysis. Results indicate the model accurately predicts lower head failure behavior, and Larson-Miller life fraction and Hedl-Dorn parameter criteria accurately assess lower head integrity. Part II presents applied research after validation and preliminary analysis. Using the improved ISAA, melt pool behavior and lower head thermal–mechanical response were analyzed for a CAP1400 small break loss-of-coolant accident (SBLOCA), assuming multiple safety system failures. Results indicate the bottom of the lower head melt pool didn’t form a hard shell due to high heat release rate, only an oxide shell layer around the second layer. Decay heat from melt pool components cannot be dissipated, leading to lower head failure. Further External Reactor Vessel Cooling (ERVC) heat transfer model analysis and research are needed in ISAA. The two developed mechanical analysis models predict material failure at high temperatures, and the timing and location of lower head failure are consistent, at approximately 16,000 s at 25.38°±5.47° on the lower head. The predicted failure mode is similar to Part I validation, indicating both Larson-Miller life fraction and Hedl-Dorn parameter criteria provide consistent lower head integrity judgments.

Quantitative assessment of brain injury and concussion induced by an unintentional soccer ball impact

BackgroundAccidental impact on a player's head by a powerful soccer ball may lead to brain injuries and concussions during games. It is crucial to assess these injuries promptly and accurately on the field. However, it is challenging for referees, coaches, and even players themselves to accurately recognize potential injuries and concussions following such impacts. Therefore, it is necessary to establish a list of minimum ball velocity thresholds that can result in concussions at different impact locations on the head. Additionally, it is important to identify the affected brain regions responsible for impairments in brain function and potential clinical symptoms. MethodsBy using a full human finite element model, dynamic responses and brain injuries caused by unintentional soccer ball impacts on six distinct head locations (forehead, tempus, crown, occiput, face, and jaw) at varying ball velocities (10, 15, 20, 25, 30, 35, 40, and 60 m/s) were simulated and investigated. Intracranial pressure, Von-Mises stress, and first principal strain were analyzed, the ball velocity thresholds resulting in concussions at different impact locations were evaluated, and the damage evolution patterns in the brain tissue were analyzed. ResultsThe impact on the occiput is most susceptible to induce brain injuries compared to all other impact locations. For a conservative assessment, the risk of concussion is present once the soccer ball reaches 17.2 m/s in a frontal impact, 16.6 m/s in a parietal impact, 14.0 m/s in an occipital impact, 17.8 m/s in a temporal impact, 18.5 m/s in a facial impact or 19.2 m/s in a mandibular impact. The brain exhibits the most significant dynamic responses during the initial 10–20 ms, and the damaged regions are primarily concentrated in the medial temporal lobe and the corpus callosum, potentially causing impairments in brain functions. ConclusionsThis work offers a framework for quantitatively assessing brain injuries and concussions induced by an unintentional soccer ball impact. Determining the ball velocity thresholds at various impact locations provides a benchmark for evaluating the risks of concussion. The examination of brain tissue damage evolution introduces a novel approach to linking biomechanical responses with possible clinical symptoms.

Indirect 1H-[13C] MRS of the human brain at 7 T using a 13C-birdcage coil and eight transmit-receive 1H-dipole antennas with a 32-channel 1H-receive array.

The neuronal tricarboxylic acid and glutamate/glutamine (Glu/Gln) cycles play important roles in brain function. These processes can be measured in vivo using dynamic 1H-[13C] MRS during administration of 13C-labeled glucose. Proton-observed carbon-edited (POCE) MRS enhances the signal-to-noise ratio (SNR) compared with direct 13C-MRS. Ultra-high field further boosts the SNR and increases spectral dispersion; however, even at 7 T, Glu and Gln 1H-resonances may overlap. Further gain can be obtained with selective POCE (selPOCE). Our aim was to create a setup for indirect dynamic 1H-[13C] MRS in the human brain at 7 T. A home-built non-shielded transmit-receive 13C-birdcage head coil with eight transmit-receive 1H-dipole antennas was used together with a 32-channel 1H-receive array. Electromagnetic simulations were carried out to ensure that acquisitions remained within local and global head SAR limits. POCE-MRS was performed using slice-selective excitation with semi-localization by adiabatic selective refocusing (sLASER) and stimulated echo acquisition mode (STEAM) localization, and selPOCE-MRS using STEAM. Sequences were tested in a phantom containing non-enriched Glu and Gln, and in three healthy volunteers during uniformly labeled 13C-glucose infusions. In one subject the voxel position was alternated between bi-frontal and bi-occipital placement within one session. [4-13C]Glu-H4 and [4-13C]Gln-H4 signals could be separately detected using both STEAM-POCE and STEAM-selPOCE in the phantom. In vivo, [4,5-13C]Glx could be detected using both sLASER-POCE and STEAM-POCE, with similar sensitivities, but [4,5-13C]Glu and [4,5-13C]Gln signals could not be completely resolved. STEAM-POCE was alternately performed bi-frontal and bi-occipital within a single session without repositioning of the subject, yielding similar results. With STEAM-selPOCE, [4,5-13C]Glu and [4,5-13C]Gln could be clearly separated. We have shown that with our setup indirect dynamic 1H-[13C] MRS at 7 T is feasible in different locations in the brain within one session, and by using STEAM-selPOCE it is possible to separate Glu from Gln in vivo while obtaining high quality spectra.

Research on hydraulic characteristics’ sensitivity analysis of the hydraulic inclined shaft turning

Abstract The parameters of the hydraulic inclined shaft turning directly affects the flow field characteristics in the bending section and the construction difficulty of the bending section. Three-dimensional computational fluid dynamics (CFD) numerical simulation method was used to systematically study the hydraulic characteristics under different flow velocities, turning radii and turning angles. The results indicate that the flow velocities and the size of the turning radius have little influence on the flow velocity distribution in the bending section. The larger the turning angle, the larger the fast flow velocity area in the bending section. But the extreme values of fast flow velocity remain basically unchanged, and the length required for adjusting the flow velocity distribution after the curved section becomes longer. The faster the flow velocity, the smaller the turning radius, and the larger the turning angle, the greater the centrifugal force generated and the more pronounced the difference in pressure distribution between the inside and outside of the bend section. The head loss in the bending section is consistent with the empirical formula in the specifications. As the radius of curvature gradually increases from 1D to 3D, the head loss (primarily due to local head loss) decreases gradually. When the radius of the bending section continues to increase, the reduction in local head loss becomes less significant, but the increase in frictional head loss leads to a slight overall increase in head loss.

MixFormer: End-to-End Tracking With Iterative Mixed Attention.

Visual object tracking often employs a multi-stage pipeline of feature extraction, target information integration, and bounding box estimation. To simplify this pipeline and unify the process of feature extraction and target information integration, in this paper, we present a compact tracking framework, termed as MixFormer, built upon transformers. Our core design is to utilize the flexibility of attention operations, and we propose a Mixed Attention Module (MAM) for simultaneous feature extraction and target information integration. This synchronous modeling scheme allows us to extract target-specific discriminative features and perform extensive communication between target and search area. Based on MAM, we build our MixFormer trackers simply by stacking multiple MAMs and placing a localization head on top. Specifically, we instantiate two types of MixFormer trackers, a hierarchical tracker MixCvT, and a non-hierarchical simple tracker MixViT. For these two trackers, we investigate a series of pre-training methods and uncover the different behaviors between supervised pre-training and self-supervised pre-training in our MixFormer trackers. We also extend the masked autoencoder pre-training to our MixFormer trackers and design the new competitive TrackMAE pre-training technique. Finally, to handle multiple target templates during online tracking, we devise an asymmetric attention scheme in MAM to reduce computational cost, and propose an effective score prediction module to select high-quality templates. Our MixFormer trackers set a new state-of-the-art performance on seven tracking benchmarks, including LaSOT, TrackingNet, VOT2020, GOT-10 k, OTB100, TOTB and UAV123. In particular, our MixViT-L achieves AUC scores of 73.3% on LaSOT, 86.1% on TrackingNet and 82.8% on TOTB.

지방정부 ESG 경영 도입 및 적용을 위한 기초 연구:ESG와 지속가능성, 만족도 인과성 분석

This paper attempted to present policy implications by reviewing the sustainability of local government ESG administration and evaluating resident satisfaction. To this end, the necessity of introducing ESG management and administration and the components of environment(E), society(S), and governance(G) were reviewed. In addition, we investigated how ESG administrative activities affect local governments' sustainability and residents' satisfaction. A survey method was used targeting local residents and public officials, and influential factors and implications for ESG administration were discovered through various analyses. First, among environmental, social, and governance issues in local government ESG activities, the environment(E) field is closely related to the daily lives of local residents, such as climate crisis, energy, and greenhouse gases (fine dust), so it receives more attention from residents than other issues. I was focused. Second, the social(S) field has a strong relationship with local quality of life(QOL) conditions. Issues that are causing difficulties include population issues, decline, regional extinction, and human relations. If each local government can solve population, birth, and extinction problems, satisfaction will increase accordingly. Third, governance(G) issues were analyzed more highly than social(S) issues, which is due to the increase in local governments' civil complaint response administration and resident participation projects. It was also found that local government heads spend a lot of time responding to and processing civil complaints. In order to strengthen local governments' ESG administrative activities, it is necessary to establish specific guidelines for governance establishment and operation and institutionalize continuous performance inspection.

HOW LOCAL DEMOCRATIC BACKSLIDING? SINGLE CANDIDATE, PRAGMATISM AND UNCOMPETITIVE LOCAL HEAD ELECTION IN INDONESIA

This paper will examine how pragmatism has created rational choice behavior in candidate selection. Pragmatism has resulted in single candidates for local heads, which makes local democracy uncompetitive. The research method used is an explanatory approach that aims to explain how pragmatism as a rational choice behavior in the local government head election. Data were collected, compiled and analyzed using Nvivo 12 Plus software. The results showed that political parties as political institutions are very pragmatic in the selection of candidates for local heads. The incumbents utilized the support of almost all political parties based on clientelistic and programmatic relations. This has led the candidate selection process to prioritize pragmatic aspects, especially financial support, acceptability, and electability of candidates. The candidate selection process no longer determines ideological values at the official candidate selection process. Financial support for candidates has the highest priority for political parties in determining their endorsements in regional head elections. Meanwhile, the acceptability aspect refers to the dominant acceptance of all elites, cadres, and the mass base of supporters of the selected candidate. Electability is also a priority, although it is considered that electability trends are dynamic and able to change based on the level of competition. The behavior of political party elite actors and local head candidates eventually forms a rational choice pattern that makes local democracy backsliding.

GP-HTNLoc: A graph prototype head-tail network-based model for multi-label subcellular localization prediction of ncRNAs

Numerous research results demonstrated that understanding the subcellular localization of non-coding RNAs (ncRNAs) is pivotal in elucidating their roles and regulatory mechanisms in cells. Despite the existence of over ten computational models dedicated to predicting the subcellular localization of ncRNAs, a majority of these models are designed solely for single-label prediction. In reality, ncRNAs often exhibit localization across multiple subcellular compartments. Furthermore, the existing multi-label localization prediction models are insufficient in addressing the challenges posed by the scarcity of training samples and class imbalance in ncRNA dataset. To address these limitations, this study proposes a novel multi-label localization prediction model for ncRNAs, named GP-HTNLoc. To mitigate class imbalance, GP-HTNLoc adopts separate training approaches for head and tail location labels. Additionally, GP-HTNLoc introduces a pioneering graph prototype module to enhance its performance in small-sample, multi-label scenarios. The experimental results based on 10-fold cross-validation on benchmark datasets demonstrate that GP-HTNLoc achieves competitive predictive performance. The average results from 10 rounds of testing on an independent dataset show that GP-HTNLoc outperforms the best existing models on the human lncRNA, human snoRNA, and human miRNA subsets, with average precision improvements of 31.5%, 14.2%, and 5.6%, respectively, reaching 0.685, 0.632, and 0.704. A user-friendly online GP-HTNLoc server is accessible at https://56s8y85390.goho.co.

Local Head Losses And Drag Coefficients Characterization In Coastal Infrastructures

Some coastal infrastructures (i.e. intakes, outfalls, gates) incorporate singular elements (meshes, nets or grids) which, through their interaction with the water flow, can produce large changes in the water level (upstream and downstream) and forces on them. Therefore, an accurate definition of local head losses (to characterize water level changes) and drag coefficient (to characterize drag forces) allows to optimize their designs (configuration and geometric definition).

Computational analysis of the anode-directed streamers propagation in atmospheric pressure C4F7N/N2 mixtures

In recent years, interest in synthetic C4F7N as a gas insulator has been growing due to its unique insulation properties and low global warming potential. In spite of this, very few studies are devoted to the analysis of the electric breakdown of C4F7N and its mixtures with other dilutants such as CO2 and N2. In the present paper, we use a two-dimensional fluid model to analyze the electrical breakdown of the atmospheric pressure C4F7N/N2 mixture. We establish the influence of the C4F7N fraction in the mixture and the cathode voltage rise rate on the breakdown voltage. We find that the ratio between the electron attachment frequency and the voltage rise rate defines the streamer parameters. Namely, if the time scale of electron attachment to C4F7N is much faster than the voltage rise rate, the plasma electronegativity of the streamer body and of its head is extremely high, and it is difficult to define exactly the streamer head location. In the opposite case of the fast rise rates, the conventional streamers with sharp heads were obtained.

A study of the flow characteristics with natural accumulations of vegetative floating matter at trash racks

Rivers and reservoirs with rich vegetation resources may suffer from the natural accumulations of vegetative floating matter (VFM) at trash racks. The relationship between hydraulic parameters and physical characteristics of natural VFM accumulations needs to be developed. This research experimentally simulated the natural VFM (leaf-type, fascicled-type, and mixed-type) accumulation at trash racks, varied by flow rate, VFM quantity, and release position. The blockage of cross-section, increase in local head loss, and changes in flow distribution with a natural VFM accumulation were quantified. The results indicate that the hydraulic parameters and physical characteristics of natural VFM accumulations are closely related to the structure of VFM. The head loss and the percentage of gap flow due to the accumulations of leaf type-VFM are numerically lager than that of fascicled-type VFM. Furthermore, the head loss and flow distribution were estimated based on the types of VFM, blockage ratio and the original Froude number. Considering the natural accumulation, a total flow prediction was proposed without estimating the resistance coefficient. This work provided basis for the management and prediction of VFM accumulations in river systems.

Follicular (Infundibular-Tricholemmal) Squamous Cell Carcinoma: A New WHO Entity. Clinicopathological Features in 103 Cases, Including Follow-Up and Implications for Patient Management.

Cutaneous follicular (infundibular-tricholemmal) squamous cell carcinoma (FSCC) is a new World Health Organization entity. We present the largest series of published cases, summarizing clinical data, diagnostic criteria, differential diagnosis, and implications for patient management. Cases were identified from 2004 to 2011. Inclusion criteria included discrete attachment(s) of the tumor to the overlying epidermis via follicular infundibula, tricholemmal keratinization, and cellular pleomorphism. Keratoacanthoma and lesions with adjacent bowenoid epidermal dysplasia were excluded. One hundred three cases of FSCC identified. 48.5% demonstrated completely circumscript borders ( in situ for practical purposes), 12.6% uncertain for invasion (overwhelmingly pushing borders), and only 38.8% as clearly invasive. Follicular mucin in acantholytic spaces within tumor epithelium was a distinctive finding in 57.2% of cases. Clinical data indicated predominance in elderly (median 78.5 years) men (70.4%), with preferential head and neck location (81.6%). Many were clinically suspected as squamous cell carcinoma (48.5%). However, a significant minority were clinically diagnosed as basal cell carcinoma (40.8%). This may reflect that FSCC commonly presented as a papule or nodule (51.3%). By contrast, keratoacanthoma was less frequently suggested (17.2%) and still fewer lesions were suspected to be actinic keratosis/Bowen's disease (13.6%). Follow-up in 82 cases (median 26.5 months, range 3-144) identified 5 (6.1%) local recurrences. There was no instance of metastasis in the subgroup of lesions with completely circumscript borders. Three of 45 (6.7%) patients, with follow-up, considered to have tumors with invasive pushing, and/or infiltrative borders developed lymph node metastases. FSCC is identified as a common skin cancer, incorporating historical entities, such as infundibular carcinoma and tricholemmal carcinoma, with readily identifiable histologic features. Correct diagnosis has implications for patient management; a significant subgroup of lesions show completely circumscript borders that are considered in situ for practical purposes.
