Triple-console robotic telesurgery: first impressions and future impact.

Telesurgery has been recently gaining momentum as a natural evolution of robotic surgery. Besides providing expert surgical care to patients who cannot geographically access it, telesurgery can also facilitate surgical collaboration between surgeons who might need urgent assistance or coaching experts. The idea of having two consoles, with one remote and one local, has been the ideal setup for such ecosystems. However collaborations can take on many forms and might require more than one remote surgeon, depending on procedure complexity and surgeon availability. The objective of the study was to describe our perspectives and experience performing telesurgery on one patient, using three surgeon consoles for three surgeons, operating from three separate cities. In November 2023, a triple-console, robot-assisted radical prostatectomy (RARP) was performed in a collaborative effort among three surgeons in three separate locations employing telesurgery using the Kangduo Endosopic Surgical Robot (KD-SR-01, Sagebot Medical). The furthest distance between participants was approximately 2600km between Beijing and Hainan. We described and illustrated the applications and outcomes of this procedure to treat a single patient with prostate cancer. The local surgeon, along with the operating room team, and the patient were in Hainan, while the other two surgeons were in Beijing and Hunan Telesurgery command centers. The procedure lasted approximately 120min and there were no intra- or postoperative complications. Estimated blood loss was 100ml. The patient was ambulating 4h after surgery and remained in the hospital for 2days secondary to the postoperative care protocol followed by the local team taking care of the patient. The Foley catheter was removed on postoperative day 7 without complication. The final pathology was ISUP Grade Group 4 (Gleason score 4 + 4 = 8) T2cN0 with negative surgical margins. Our experience shows that telesurgery involving multiple surgeons at multiple remote locations is possible and can be completed safely with low-latency connections via available telecommunication networks.

Impacts of GCP Distributions on UAV-PPK Photogrammetry at Sermeq Avannarleq Glacier, Greenland

Real-Time/Post-Processing Kinematic (RTK/PPK) technology has been widely applied in Unmanned Aerial Vehicle (UAV) photogrammetry in glaciological research. Considering that ground control points (GCPs) cannot be set on glaciers, evaluating the impacts of one-sided distribution is essential. In this study, 8571 images were captured at Sermeq Avannarleq glacier in western Greenland from 4 August 2021 to the 6th, covering approximately 85 km2, with the furthest distance being 13.22 km away from the coastline. Benefited by the meandering coastline, 11 roving stations roughly uniformly distributed on bare rock were surveyed with the RTK technique. PPK-geotagged images were processed in Agisoft Metashape Professional to derive the DSMs, utilizing eight different configurations of GCP distributions that gradually extended longitudinally (along the glacier flow direction) to the upper part of the glacier. The accuracy of DSMs was evaluated by referring to the validation points (VPs) that were not employed in the Bundle Block Adjustment (BBA). The results indicated that the RMSE values of the easting, northing, and height of the reconstruction model georeferenced by only PPK geotagging (no GCPs applied) were 0.038 m, 0.031 m, and 0.146 m, respectively. Applying four GCPs located at one side of the region but with both longitudinal and lateral distribution improved the RMSE values in easting, northing, and vertical to 0.037 m, 0.031 m, and 0.081 m, respectively, and these values were stable even when distributing four GCPs evenly or when increasing the number of GCPs to eleven. Moreover, the cross-validation with ICESat-2 and ArcticDEM performed only at an off-glacier region also suggested that vertical accuracy shows significant improvements for every configuration of GCPs compared to the reconstruction model optimized only by PPK, but such improvements were not obvious if the number of GCPs exceeded four. Moreover, no elevation ramps appeared in the UAV DSM, even for the GCP configuration with only two GCPs distributed at the terminus. Therefore, combining PPK with only a few GCPs but distributing in both directions of the surveying region can offer a viable solution for obtaining glacier DSMs at the coastline with decimeter-level accuracy.

The legal and illegal supply chains of sea turtle eggs in Costa Rica

Many poor rural communities rely on biodiversity to fulfil basic livelihood requirements. Trade bans of natural resources often conflict with poverty alleviation and can stimulate illegal trade. Understanding markets, prices and profitability along both legal and illegal trade chains is crucial if appropriate regulatory mechanisms are to be implemented. Using the legal extraction of sea turtle eggs from Ostional, we used a mixed-methods approach to analyse the legal domestic supply chain. We used semi-structured interviews, questionnaires and data on the volume and destinations of egg sales to conduct a value chain analysis. We found an inequitable distribution of revenue along the legal supply chain, with middlemen profiting the most. Geographical barriers to trade flows and competition with illegal trade meant higher profits were achieved by sending the largest volume of the furthest distance. However, this increased the vulnerability of local traders to fluctuations in supply. Comparing legal and illegal trade routes, we identified potential laundering hotspots on the Caribbean coast of Costa Rica. Illegal eggs were cheaper than legal eggs available from Ostional. However, given the volume of Ostional eggs supplying the Caribbean and the fragility of local trader livelihoods, we advise caution in altering any management plan that could impact supply to this region, fearing a dwindling supply of legal eggs may stimulate illegal extraction in the Caribbean. Our research is directly relevant to the policies of the Convention on International Trade in Endangered Species, Convention on Biological Diversity and UN Sustainable Development Goals as our research enhances our understanding of how natural resource use can help alleviate poverty, improve local livelihoods and inform policy regarding wildlife laundering.

The Impact of Flow Patterns Due to the Cold Lahar Flooding of Mount Semeru on the Collapse of the Bridge Connecting Malang District and Lumajang District

The flow patterns that occur in rivers as a result of falling cold lava often cause damage here and there. This incident cannot be separated from the large volume of water mixed with material that crosses the open channel which is caused by input water supply or water supply from river reservoirs crossed by cold lava. by water researchers for water mixed with volcanic eruption material suspended above. The event of water flowing through a river is influenced by the presence of the surface profile of the river bed and the various widths of the river that occur. If a volume with a certain viscosity is given, a thick flow will be formed that can be seen on the surface of the river, while that which is not visible to the naked eye above the water surface is called thick viscosity. If the runoff of cold lava material that occurs in the channel is not measured, it will result in wild jumps. The wild and viscous jumping structure that has been arranged can be observed as to how the flow pattern occurs. To avoid not detecting the flow pattern, water measuring structures are needed, one of which is a threshold with openings below or what is known as flow above the threshold along with existing bridge buildings around it. This sluice gate is easy to operate manually. The need for water operations with excess water availability is not an easy thing to calculate, because of the influence of depth and jumps that occur around the bridge, hydraulic jump patterns often ignore this measurability, this will be an obstacle if there is a large supply of cold lava. mixed with rainwater during peak conditions in the drainage process. Observations of this completion need to be proven by carrying out model tests using a tool known as the Threshold which produces a water jump along with the material. This requires further investigation for research in the model channel. For modeling thresholds and bridges connecting between plains, this tool provides instruments and many threshold treatments as well as regulating pressurized water with a pump at a certain flow rate in a measurable manner. To analyze the height of building damage, determine the flow pattern, speed by observation, test results with valve openings on certain pumps, researchers tested and measured the position of cold lava deposits one by one, the position of the slope of the river in certain sections, starting with an opening of 0.5; 0.75, read the instrument, move the threshold position from a bridge distance of 20 cm, 40 cm, to the furthest distance of 240 cm. Make graphs of test results for the threshold of the bridge opening transfer tool by testing the tool and opening 3 times for each pump opening, recording, mapping the depth values, jump length and travel time of the instrument on the test tool. Recommend the results of the analysis of the Threshold and Bridge tests to provide information to bridge construction planners that the test results with various threshold positions in certain conditions have the value of the Glidik II bridge collapse, the jump with the travel time of the speed of passing cold lava. Next, the bridge is determined and the next threshold can be used to determine how severe the damage is to the river. This research is laboratory research with threshold and bridge models. The target of this output is a journal article resulting from a simulation of determining the flow pattern that occurs in the channel by shifting the position of the threshold relative to the location of the bridge from the channel model with various diameter sizes of the model material, the results of which are in the form of a table and graphed on the part modeled in the water laboratory, especially flow with sediment and cold lava material. The results of this section were observed up to the collapse of the bridge at a depth of 4.5 cm with an opening of ½ second to 37 (on the model scale) observed or a depth of 45 meters (on the empirical scale). to then be written in the form of an article to be included in an international journal.

Selection of well opening schedules in pre-salt reservoirs using WAG-CO2

In field development projects involving many wells, the limitation of available rigs can increase the need for investments. In our literature research about the definition of well opening schedules, we found some proposals but could not find studies that deep dive into this topic, nor any that propose an approach that could be applied to the Brazilian pre-salt fields. Therefore, this research focuses on evaluating the influence in the NPV of well opening schedule of a project using WAG-CO2, inspired in pre-salt fields, and we propose a simple procedure to specify the well opening schedule without having to perform many simulations or complex analysis. We used the UNISIM-II-D-BO benchmark (synthetic simulation model with characteristics of a Brazilian pre-salt field) and a well configuration proposed in a previous study, with 11 producers and 10 injectors. First, we calculated the distance between the producer and injector wells and evaluated the well economic indicator (WEI) of each well by opening all at the same time at the beginning of the production schedule. We then evaluated 252 combinations of those injector wells, where five of them were injecting water and the other five were injecting gas, from where we defined three reference alternatives to check the repeatability of the results. With all these data, we tested predefined schedules: (1) with the 1st injector well injecting only gas or participating in the WAG cycle; (2) the producers' opening sequence based on their WEI; (3) the injectors’ opening based on their WEI or distance to producers; and (4) testing the relationship between producers and injectors (number of producers to open before the injectors), making sure that all the gas could be reinjected. For comparison purposes, we then run an optimization algorithm to select the schedule, using 2,660 simulations. At the end, we verified that the difference between the optimization with the algorithm (demanding thousands of simulations runs) and the proposed schedules (demanding few simulations) in the NPV was about 2%. Thus, to speed-up decision making, it is possible to have an opening schedule with good performance considering a simple procedure, as follows: 1st injector well collaborating with the WAG; producer wells opening from the highest to the lowest WEI; injector wells opening from the closest to the furthest distance to the producers; and the relationship between producers and injectors has to be investigated, not only aiming to find the best economic return, but also because of the environmental restriction (the need to reinject all the produced gas). This procedure reduces the number of simulations that must be performed if an engineer decides to use an optimization technique.

Investigation on the contaminate of hand washing activities on the surface of environmental objects in intensive care unit

To detect the contaminate of faucets in hospitals and the splash during hand washing, and to explore the reasonable layout of hand washing pools. Two faucets with roughly the same spatial layout in the ICU of a third-class first-class general hospital were selected, and the farthest splashing distance and specific splashing points were measured by color paper. Samples were detected by ATP detection technology and routine microbial detection method, and the contaminate of faucets was analyzed. After 72 h of daily hand-washing activities, the furthest distance to the splash point was about 100 cm around the faucet, and the place 40–110 cm around the faucet was contaminated seriously. The farthest distance that the splash point reached was about 80 cm around the faucet with the center of the circle, and the area 40–60 cm around the faucet was heavily contaminated. The distance from the water outlet of the long handle and the short handle faucet to the detection point had a high negative correlation (r = − 0.811, P < 0.001) and a moderate negative correlation (r = − 0.475, P = 0.001) with the number of splash points, respectively. The qualified rates of ATP detection and microbial culture were 25% and 15%, respectively. Pseudomonas aeruginosa, Staphylococcus epidermidis, and other pathogenic bacteria were detected in the water outlet of the faucet and the surrounding environment. Safe hand hygiene facilities are one of the important guarantees of hand hygiene effect. Clean objects and objects related to patients should not be placed within 1 m range near the water outlet of faucet. Anti-splash baffle should be installed as much as possible when conditions permit to reduce the contaminate caused by splash during hand washing.

Quantitative Fire Risk Assessment of Crude Oil Tank at Company A

The oil and gas industry has a high risk of losses due to fire. There have been several fire incidents in the oil industry involving fires in crude oil tanks. The objective of this research is to assess the level of fire risk in Crude Oil Tank T32 at Company. The research method used is to analyze the frequency of fire occurrences using event tree analysis and modeling the consequences of fires using ALOHA software. After conducting frequency analysis and consequence modeling, individual risk and social risk are calculated. Results: Based on the results of consequence modeling, the furthest distance for heat radiation with a 100% risk of death is 84 meters. The largest risk calculation result is in the leaky tank scenario with a hole size of 100 mm with an individual risk value of 1,84 x 10-8 and a social risk value of 3,13 x 10-7. The results of the T32 tank fire risk assessment at Company A's oil collection tank facility show that individual and social risks are still within the acceptable risk category according to the UK HSE Risk Acceptance Criteria. Even though the risk of a fire incident is still within acceptable limits, risk control efforts still need to be carried out so that the risk remains within acceptable tolerance limits

Clinical Importance of Grading Tumor Spread through Air Spaces in Early-Stage Small-Lung Adenocarcinoma.

This study aimed to identify the clinical manifestation and implications according to the grading of tumor spread through air spaces in early-stage small (≤2 cm) pathological stage I non-mucinous lung adenocarcinomas. Medical records of patients with pathological stage I tumors sized ≤2 cm were retrospectively reviewed and analyzed. The furthest distance of the spread through air spaces from the tumor margin was measured on a standard-length scale (mm). Enrolled patients were categorized into spread through air spaces (STAS) (-) and STAS (+), and STAS (+) was subdivided according to its furthest distance as follows: STAS (+)-L (<2 mm) and STAS (+)-H (≥2 mm). Risk factors for STAS (+) included papillary predominant subtype (p = 0.027), presence of micropapillary patterns (p < 0.001), and EGFR (p = 0.039). The overall survival of the three groups did not differ significantly (p = 0.565). The recurrence-free survival of STAS (+)-H groups was significantly lower than those of STAS (-) and STAS (+)-L (p < 0.001 and p = 0.039, respectively). A number of alveolar spaces were definite risk factors for STAS (+)-H groups (p < 0.001), and male gender could be one (p = 0.054). In the patient group with small (≤2 cm) pathological stage I lung adenocarcinomas, the presence of STAS ≥ 2 mm was related to significantly lower recurrence-free survival. For identifying definite risk factors for the presence of farther STAS, more precise analysis from a larger study population should be undertaken.

Place-Based Differences in the Association Between Greenspace and Suicide-Related Outcomes Among Young People

PurposeThis study investigated place-based differences in the association between greenspace and suicide-related outcomes (SROs) among young people, guided by the following two objectives: (1) Contextualize place-based differences in the association between greenspace and SRO prevalence among young people at the community level in five different urbanities (urban, suburban, micropolitan, small towns, and rural/isolated communities) and (2) identify which greenspace metrics (quantity, quality, or accessibility) are most protective for SROs at the community level. MethodsPublicly available greenspace datasets were used to derive greenspace quantity, quality, and accessibility metrics. SRO emergency department visits for young people were identified from 2016–2019 in North Carolina, USA. Generalized linear models investigated the association between greenspace metrics and community-level drivers of SRO prevalence. Shapely additive explanations confirmed the most important greenspace variables in accurately predicting community-level SRO prevalence. ResultsThe prevalence of SROs was highest in communities with the least amount of public greenspace; this association was most pronounced in suburban communities, with SROs 27% higher in suburban communities with low quantities of greenspace (PRRUrban: 1.11, confidence interval [CI]: 1.08–1.13; PRRSuburban: 1.27, CI: 1.10–1.46; PRRSmallTowns: 1.21, CI: 1.05–1.39), and in communities with the worst greenspace accessibility (i.e., furthest distance to nearest greenspace) (PRRUrban: 1.07, CI: 1.04–1.10; PRRRural&Isolated: 1.95, CI: 1.54–2.49). DiscussionOur analysis provides place-based, community-specific findings to guide targeted greenspace interventions aimed at addressing the rising prevalence of SROs among young people. Our findings suggest that greenspace quantity interventions may be most effective in urban, suburban, and small-town communities, and greenspace accessibility interventions may be most useful in urban and rural/isolated communities.

Abstract LB437: Development of a bladder cancer-on-a-chip assay to assess the invasive potential of bladder cancer cells

Abstract Goals: The primary goal of this study was to develop a 3D functional bioassay to assess the relative invasiveness of bladder cancer cells. This model will support the testing of migrastatic drugs and investigation of the molecular mechanisms which allow for bladder cancer cell invasion to occur. Methods: Our model uses an organ-on-a-chip platform to assess bladder cancer cell invasiveness. This platform supports 3D culture of cells as well as pharmacokinetic studies. Our chips were designed to have a center channel to hold cells supported in Matrigel®, 2 adjacent side channels filled with Matrigel® only, and 2 outer media channels. Total cell and Matrigel® side channel length is 3 cm, channel height is 150 µm, and each channel width is 1 mm. Four bladder cancer cell lines (MB49, T24, J82, RT4) and cells isolated from a mouse bladder were used to develop our model. Cells were mixed with 1:1 media and Matrigel® and a total of 5,000 cells/µl introduced into the center channel. The 2 adjacent side channels were then filled with Matrigel®. The upper media channel was filled with 10% FBS cell culture media while the lower media channel was filled with 1% charcoal stripped cell culture media to thereby create a nutrient and growth factor gradient. Invasion of cells into the Matrigel®-containing side channels was assessed every 24 hours. Using the ImageXpress machine (Molecular Dynamics), we measured the furthest distance travelled by the cells. The chips were then fixed in 4% paraformaldehyde and stained using FITC-phalloidin and DAPI. Results: J82 and T24 cell lines, derived from patients with muscle invasive bladder cancer, and the MB49 cell line, a highly invasive mouse bladder cancer cell line, started invading into the Matrigel® side channels within 24 hours. T24, J82, and MB49 cells moved a maximum of 110, 87, and 170 µm by 48 hours, respectively. In contrast, RT4 cells, derived from a patient with non-invasive bladder cancer, took 48 hours to invade the Matrigel® channels and only invaded a maximum of 3 µm. Cells isolated from a mouse bladder did not invade into the Matrigel® side channels but survived within the chips for over 20 days. Staining of chips with DAPI and FITC-phalloidin allowed for clear visualization of cells and the actin cytoskeleton and demonstrated that immunostaining of cells within chips is possible. Conclusions: Our chip model allows for studying the invasiveness of bladder cancer cells and immunostaining experiments which can be used to assess the molecular mechanisms which drive invasion. It can also support the growth and assessment of primary cells. This model has the potential to improve bladder cancer patient treatments and outcomes by providing a physiologically relevant system to test new and existing drug combinations and to better understand the molecular mechanisms which drive bladder cancer cell invasion.

Regarding the Marga area, it complies with the ITU-T G.984 standard, which is the GPON network implementation standard.

Towards Automatic Boundary Detection for Human-AI Collaborative Hybrid Essay in Education

The recent large language models (LLMs), e.g., ChatGPT, have been able to generate human-like and fluent responses when provided with specific instructions. While admitting the convenience brought by technological advancement, educators also have concerns that students might leverage LLMs to complete their writing assignments and pass them off as their original work. Although many AI content detection studies have been conducted as a result of such concerns, most of these prior studies modeled AI content detection as a classification problem, assuming that a text is either entirely human-written or entirely AI-generated. In this study, we investigated AI content detection in a rarely explored yet realistic setting where the text to be detected is collaboratively written by human and generative LLMs (termed as hybrid text for simplicity). We first formalized the detection task as identifying the transition points between human-written content and AI-generated content from a given hybrid text (boundary detection). We constructed a hybrid essay dataset by partially and randomly removing sentences from the original student-written essays and then instructing ChatGPT to fill in for the incomplete essays. Then we proposed a two-step detection approach where we (1) separated AI-generated content from human-written content during the encoder training process; and (2) calculated the distances between every two adjacent prototypes (a prototype is the mean of a set of consecutive sentences from the hybrid text in the embedding space) and assumed that the boundaries exist between the two adjacent prototypes that have the furthest distance from each other. Through extensive experiments, we observed the following main findings: (1) the proposed approach consistently outperformed the baseline methods across different experiment settings; (2) the encoder training process (i.e., step 1 of the above two-step approach) can significantly boost the performance of the proposed approach; (3) when detecting boundaries for single-boundary hybrid essays, the proposed approach could be enhanced by adopting a relatively large prototype size (i.e., the number of sentences needed to calculate a prototype), leading to a 22% improvement (against the best baseline method) in the In-Domain evaluation and an 18% improvement in the Out-of-Domain evaluation.

LoRa based long-range traceable life jacket system design

It is recorded that around 100 people per year die due to fishing boat accidents, the majority of whom are small fishermen with vessels under 10 GT. LoRa is a license-free power-saving long-distance communication technology that can send data packets of up to 15 km in the ocean. The longrange power can be used to determine the location of fishermen when an accident occurs at sea. This research aims to implement and test the performance of LoRa Ebyte E22-400T30D for sending coordinate data on fishermen’s whereabouts in the form of life jackets. The performance observed is the relationship between the distance and the RSSI value obtained. The tests were performed until the furthest distance was reached. The test was carried out at Pangandaran Beach, and the receiver was placed at an altitude of 129 m toward the beach. The data will be displayed and stored on the Thinger.io website. The test results obtained with the furthest distance achieved were 12.983 km with a battery life of 5.99 hours. The RSSI value obtained tended to worsen with increasing distance. Apart from the distance, it was also found that obstructions in the form of trees could reduce the RSSI value.

Pengaruh Besar Sudut pada Servis Bulu Tangkis dengan Gerak Parabola

Badminton athletes apply various techniques and strategies when competing. One technique is to apply the correct serve to bounce the shuttlecock. The aim of this research is to determine the effect of how big the angle of the racket can be over the net and on target. This research applies an experimental method, which was chosen with the main aim of this research being to test an object. In this context, the focus is on angle variations to determine the optimal angle for the badminton player when serving so that the shuttlecock can fall over the net with different elasticity. In this experiment, the parabolic motion recordings were analyzed using the Tracker application to obtain the initial speed for each angular variation. The shuttlecock's initial speed can be used to calculate the shuttlecock's highest point, the time it reaches its maximum height, and the shuttlecock's furthest distance. The results showed that differences in the initial angle of the backhand serve caused differences in the maximum height, distance and time achieved.

Sistem Pemantauan Slot Parkir Menggunakan Sensor Ultrasonik JSN-SR04T dan Pengenalan Plat Nomor Kendaraan dengan ESP32-CAM

A parking slot monitoring system prototype has been produced using the JSN-SR04T ultrasonic sensor and vehicle license plate recognition with ESP32-CAM. The system was created to make it easier for motorists to monitor the availability of parking slots remotely by utilizing Telegram which is connected to the ESP32-CAM module and Arduino Mega 2560. The ultrasonic sensor detects the distance of vehicles entering or exiting the parking lot, then a servo motor opens the entry and exit bars. Vehicle users can monitor the availability of parking slots on the Telegram bot. In each slot there is an ultrasonic sensor that detects the distance so that it can find out whether there is a vehicle in the slot. The test results show that the ultrasonic sensor has an average error percentage of 0.65%. The parking barrier can be opened when the ultrasonic sensor detects the presence of a vehicle at the entrance or exit and the ultrasonic sensor can detect the presence of a vehicle according to the conditions in the slot. The system is equipped with vehicle license plate character recognition using the Optical Character Recognition (OCR) method. Through the ESP32-CAM module camera webserver, the OCR program can detect vehicle plates with the furthest distance of 140 cm using video resolution (400x296) and 300 cm using video resolution (1600x1200). The OCR program can read the vehicle plate characters correctly and the results for the number of characters obtained correspond to the license plate being tested, then the vehicle plate data is stored in the database

Abstract P3120: Persistent Cardiac Dysfunction In Ovariectomized Independent Of Metabolic Disturbance

Objectives: Postmenopausal women are known to develop metabolic syndrome and cardiovascular disease. We hypothesize that a murine model of ovariectomy (OVX) and high-fat diet (HFD), simulating a post-menopausal milieu, will have decreased activity, changes in body composition, and impaired cardiac activity. Methods: From 5 weeks of age, 11 C57BL/6 mice were fed a HFD and 10 were fed a control diet (CTL). At 12 weeks, 11 mice (5 HFD, 6 CTL) were ovariectomized (OVX). At 30 weeks mice body composition was analyzed with EchoMRI. Metabolic activity was monitored in Promethion metabolic cages for 48 hours. Transthoracic echocardiography (TTE) was performed while mice were anesthetized with 2.5% isoflurane. Results: The OVX mice traveled the furthest distance, and HFD+OVX the shortest distance. HFD+OVX and HFD had increased energy expenditure and higher fat mass compared to CTL (Figure 1). All groups had increased LV Mass, and worse systolic function to control (Table 1). Conclusion: Ovariectomy could be associated in systolic dysfunction independent of development of metabolic syndrome.

Application of the Topsis Method in Selecting the Best Laying Chicken Feed

A person's limited ability in a particular field makes them think hard about getting a job that can fulfill their daily needs. Now many people are starting to try to switch to the world of animal husbandry. One of them is raising chickens to take their eggs. Choosing good laying hen feed is a very important main factor, especially for consumption by laying hens. Therefore, a decision support system was designed in selecting the best laying hen feed using the Techinique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The TOPSIS method is an approach that determines solutions based on the closest distance from the positive ideal solution and the furthest distance from the negative ideal solution in order to obtain the optimal alternative. The result achieved is that the system is able to show which laying hen feed has the best quality which will become laying hen feed for laying hen breeders based on predetermined criteria so that Sinar Animal Husbandry can easily determine the best laying hen feed . The results of calculations using the Topsis method showed that alternative A3, namely HI-PRO-VITE 124, had the highest value with an alternative value of 0.6568

Decision Support System for Admission of Regional Government Scholarships in Merauke Regency Using the TOPSIS Method

Scholarship is a government program given to high school graduates to be able to continue their studies at the tertiary level. This is as stipulated in the Regent Regulation (PERBUP) No 25 of 2019 concerning "providing scholarships and educational assistance to students of Merauke Regency". In the scholarship acceptance selection activities in 2019, approximately 103 applicants were recorded, and 74 were successfully accepted. The process of selecting prospective scholarship recipients is currently being carried out, namely checking and comparing one by one with the applicant's data. Based on data in 2019, where there are applicants whose report card value data is incomplete but is accepted for a scholarship. This is considered to have an impact on the decision-making results of prospective scholarship recipients in subsequent years. In order to assist KESRA in selecting scholarship recipients, these obstacles can be overcome by using a decision support system. The design of this decision support system is carried out using the TOPSIS method, namely selecting the alternative that is the shortest distance from the positive ideal solution and the furthest distance from the negative ideal solution. The results obtained in this study are a system that can assist the People's Welfare in determining the selection of scholarship recipients based on the three predetermined criteria. Testing the accuracy of the system obtained is 67% and for testing the questionnaire to obtain a percentage of 66.67% which is in the "Agree" category.

Seismic fragility of low-rise piloti buildings based on 2017 Pohang earthquake damage

Due to the 2017 Pohang earthquake, many low-rise piloti buildings suffered minor to severe damage. Low-rise piloti buildings in Korea are generally both vertically and horizontally irregular systems. The first floor is a weak and soft story, and the core wall is located at the corner or edge of the plan creating a horizontal irregularity. Furthermore, the damage investigation indicates that the insufficient amount of column hoops and poor detailing of reinforcement. It was presumed that the combination of soft story, torsional behavior and poor detailing brought brittle failure at the columns located at the furthest distance from the core. Such a brittle and irregular nature makes it difficult to predict damage with a HAZUS-type approach, which uses seismic fragility functions defined in terms of the spectral displacement and the capacity spectrum method based on pushover analyses. Comparison of pushover analysis results of piloti buildings indicated that location of peak and overall deformation capacity differed with the intensity of the torsional behavior and failure mode of the column. Therefore, this study aimed to develop an improved seismic fragility function for piloti buildings. To reflect the observed damage, the use of damage criteria based on member performance, including stress and strain, and spectral acceleration was proposed. Fragility functions for the piloti buildings were constructed by using three-dimensional incremental dynamic analyses. Damage estimates for piloti buildings in the target area that were obtained by using obtained fragility functions showed good correlations with damage survey data.
