    Tingginya minat pendaki gunung yang ada di Indonesia, juga meningkatkan resiko kecelakaan yang dapat  terjadi dalam pendakian. Untuk mengurangi resiko tersebut maka perlunya suatu sistem alat yang dapat membantu petugas setempat dalam pemantauan lokasi dan kondisi pendaki. Namun karena banyaknya keterbatasan sinyal dan koneksi internet yang ada pada medan pegunungan, maka perlunya media alternatif lain yang dapat digunakan sebagai media pemantauan lokasi dan kondisi pendaki. Soul Tracking Mobile Junction (STMJ) dapat menjadi solusi pada keterbatasan sinyal dan koneksi internet yang ada di gunung. STMJ menggunakan modul LoRa SX1276 berbasis Radio Frequency (RF) sebagai media transmisi. Pentransmisian data tersebut menggunkan prinsip repeater sebagai media penjembatan antar perangkat yang kemudian dapat ditampilkan melalui Aplikasi Android melalui Cloud Firestore atau melalui media Bluetooth. Dari hasil pengujian yang telah dilakukan, dapat disimpulkan sistem bekerja dengan baik dalam mentransmisikan data melaui Radio Frequency (RF) dengan pengurangan RSSI rata – rata sebesar -5,1 dBm setiap 45 m pada radius 450 m, Cloud Firestore dengan jeda rata – rata selama 0,3855 detik dan Bluetooth dengan pengurangan RSSI sebsesar -5,5 dBm setiap 5 m dengan radius maksimal 50m

    The applications of fused deposition modelling (FDM) based 3D printing have gone beyond merely simple prototypes to where functionalities are expected. One of such functionalities is the water retention properties, especially for fluid handling products, either completely waterproof or deliberately porous. Issues arise especially in determining crucial parameters and their optimization to achieve the desired water retention properties. This study established the relationship among printing parameters (layer thickness and wall thickness) and water temperature with leakage flow rate. A series of 3D printed polylactic acid (PLA) vessels were fabricated at various layer height and wall thickness. Then, the volumetric loss of water at various temperatures was measured, elapsed time was recorded, and the leakage flow rate was calculated for each 3D printed vessel. It has been found that the leakage flow rate decreased when layer height decreased, wall thickness increased, and water temperature decreased. Based on multilinear regression analysis, the magnitude of influence for the layer height was the highest, which could reach at a point where variation in wall thickness and water temperature had no effect. A regression model having 81.27% fitness that provided a quantitative relationship among all parameters had also been obtained. ANOVA analysis revealed that all parameters were statistically significant in optimizing as well as predicting the value of the leakage flow rate

    Further insights into Caprine Arthritis Encephalitis (CAE): the current status of seroprevalence among small ruminants in two selected states of Peninsular Malaysia

    Caprine arthritis-encephalitis virus (CAEV) is a member of the genus lentivirus causing caprine arthritis-encephalitis (CAE), a chronic inflammatory condition affecting the lungs, joints, udder and central nervous system of small ruminants such as sheep and goats. CAE is distributed worldwide and is recognised as a significant cause of morbidity and decreased milk production in dairy goats. Earlier studies highlighted the clinicopathological features and supplied preliminary serological evidence for the existence of CAE among selected goat herds in Malaysia. Therefore, this study aims to provide further insights into the seroprevalence and contributing factors of CAE among sheep and goat herds in two states of Peninsular Malaysia. The blood samples and biodata were randomly collected from a total of 262 individual sheep (40) and goat (222) in seven smallholder farms. Blood sera were tested for specific anti-CAEV antibodies using Qayee-Bio CAEV sandwich-ELISA test kits according to standard procedures. Our results of the study revealed 21.4% (95% CI: 15.8–28.6) apparent and 20.6% (95% CI: 14.5–27.8) true seroprevalence with significant differences (p < 0.05) in seroconversion rates between the states, farms, production systems and breeds of small ruminants. The prevalence of CAE in the Malaysian Peninsular is a potential threat to the small ruminant industry and developing agricultural economy. Further studies are required to determine the genetic characteristics, distribution and risk factors of CAEV for effective prevention and control in Malaysia

    The current pandemic COVID-19 and lockdown have worsened patients' health, especially those who suffer from an anxiety disorder. However, anxiety disorders are treatable by undergoing different therapies treatment. This paper aims to develop an Anxiety Assistant Mobile Apps Chatbot (ANUVA) for university students using Cognitive Behavioural Therapy (CBT). Structured activities are used to motivate the user to question their thought distortions and change them back. The ANUVA chatbot is developed using Evolutionary Prototyping Model. The effectiveness of the ANUVA chatbot was tested using Confusion Matrix. The result indicates that the accuracy of the ANUVA chatbot is 75%, precision 85% and recall 88%. The System Usability Scale (SUS) test was used to measure the usability, and the score shows 86.75 for the result. For future work, all the chat records will link with the counselling unit system to enhance the efficiency of the therapies

    Penilaian untuk tujuan kenaikan pangkat di Universiti Teknologi Mara (UiTM) selain daripada tujuh kriteria asas turut dinilai oleh pelajar (SUFO), rakan sekerja (CCQ) dan pemantauan. Bagi SUFO,CCQ dan pemantauan markah penilaiannya diukur secara berasingan dan keadaan ini telah menyukarkan panel kesepakaran untuk menentukan calon manakah yang lebih baik dalam sesuatu pemilihan kenaikan pangkat. Bagi mengatasi kelemahan ini penyelidik mencadangkan dibentuk sebuah indeks yang dikenali sebagai Indeks Kenaikan Pangkat UiTM Perak Berwajaran. Indeks ini adalah merupakan indeks komposit yang merangkumi ketiga-tiga sub indeksnya iaitu indeks bagi SUFO, indeks CCQ dan indeks pemantauan. Ini bermakna hanya terdapat satu nilai indeks bagi setiap calon yang menggabungkan markah ketiga-tiga perkara tersebut. Indeks yang dicadangkan ini juga adalah merupakan indeks berwajaran dengan pemberat yang berbeza bagi menggambarkan tahap kepentingan yang berbeza bagi SUFO,CCQ dan pemantauan. Dapatan kajian mencatatkan SUFO adalah paling penting dengan nilai pemberat sebanyak 0.353 diikuti oleh CCQ dengan nilai 0.352 dan 0.297 bagi pemantauan. Kedudukan seorang calon dapat ditentukan dengan memasukkan nilai pemberat kedalam persamaan indeks dan seterusnya dibandingkan dengan satu pengukuran piawai. Penggunaan indeks ini dicadangkan kepada UiTM Perak dalam penentuan kenaikan pangkat pensyarah kerana kelebihan yang ada padanya. Antara kelebihan yang dikenalpasti ialah ketigatiga markah CCQ,SUFO dan pemantauan dapat digabungkan secara komposit ke dalam satu nilai indeks sahaja. Ini lebih mudah bagi panel kesepakaran membuat penilaian kerana telah mengurangkan amalan persepsi bagi perkara yang subjektif. Disamping itu, dengan nilai indeks yang dibandingkan dengan satu pengukuran piawai bermakna kesemua calon mendapat penilaian yang adil dan saksama kerana masalah perbezaan penilaian dalam kumpulan dan masa yang berbeza telah dapat diatasi

    © 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

    © 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
