Meanings of Spatial Order in the Customary House of Sapo Battoa Kaluppini in the Enrekang Regency, South Sulawesi, Indonesia
The treasures of the traditional houses in the Nusantara
archipelago, including those in the Kaluppini community, are rich in
meanings. This study aims to examine the meanings of the vertical
and horizontal spatial orders of the Sapo Battoa customary house in
the
Kaluppini
Village,
the
Enrekang
Regency,
South
Sulawesi
Province, Indonesia.
The research adopts a qualitative method. The approach in
this research is ethnographic model. The results reveal that the
spatial order of Sapo Battoa vertically consists of three parts, (1)
sullu' bola (the legs) which horizontally consists of batu mapaccing;
kale bola (the body) which consists of kandawari, syara’, ada’, To
Manurung, kamara, tambing, dapo; and baroko' bola (the head)
which consists of tapattagoa, busaran, Sullu' bola has a meaning
associated
with
the
human
birth
process
originating
from
the
ground. (2) kale bola has a meaning associated with the human life
process that is laden with a moral message of mutual respect for
fellow beings to expect the Creator’s blessings so as to achieve
harmony in social life. (3) baroko' bola has a meaning associated
with the dedicating and serving process of human being until the
eventual returning back to God: the Creator. This study concludes
that the spatial divisions in both vertical and horizontal orders
contain sacred meanings

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Background: Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. // Methods: We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung's disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. // Findings: We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung's disease) from 264 hospitals (89 in high-income countries, 166 in middle-income countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in low-income countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. // Interpretation: Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between low-income, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030
Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.
BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700
Simulasi Pengaturan Kecepatan Motor BLDC menggunakan Software PSIM
AbstrakKrisis bahan bakar fosil menjadi salah satu alasan pengembangan teknologi dalam bidang transportasi contohnya kereta listrik dan mobil listrik. Salah satu penggerak yang saat ini banyak digunakan pada kendaraan listrik adalah motor brushless DC (BLDC) yang memiliki efisiensi tinggi, hemat biaya perawatan dan pengaturan yang mudah. Pada umumnya penelitian yang dilakukan terkait dengan motor BLDC adalah tentang pengaturan kecepatan motor, pembebanan pada motor dan yang lainnya. Penelitian ini melakukan simulasi cara pengaturan kecepatan motor BLDC dengan beban yang diubah-ubah dengan menggunakan software PSIM (Power Simulator). Data yang diperoleh melalui simulasi dengan memberikan beban maksimum sebesar 20 Nm dan hasil perhitungan menunjukan bahwa motor BLDC dengan spesifikasi yang digunakan dapat berputar dengan baik pada kecepatan 1442,05 rpm dengan efisiensi sebesar 81,25 %. Jika beban yang diberikan pada motor BLDC dinaikan menjadi 30 Nm maka kecepatan motor akan mengalami penurunan menjadi 1221,51 rpm dan efisiensi menjadi 78,34 %.Kata kunci: motor BLDC, Kecepatan motor, Beban, efisiensiAbstractThe fossil fuel crisis is one of the reasons for the development of technology in transportation, for example electric trains and electric cars. One of the movers that are currently widely used in electric vehicles is the brushless DC motor (BLDC) because this motor has advantages including high efficiency, saving maintenance costs and easy setting. In general, research conducted related to BLDC motors is about regulating BLDC motor speed, loading on BLDC motors and others. In this study a simulation was conducted discussing how to regulate BLDC motor speed with a load that was changed by using PSIM (pow3er simulator) software. From the data obtained through simulation by giving a maximum load of 20 Nm and the calculation results show that the BLDC motor with the specifications used can rotate well at speeds of 1442.05 rpm with an efficiency of 81.25%. If the load given to the BLDC motor is increased to 30 Nm, the motor speed will decrease to 1221.51 rpm and the efficiency decrease to 78.34%.Keywords: Brushless DC, speed of motor, load, efficienc
A dielectrophoresis-impedance method for protein detection and analysis
Dielectrophoresis (DEP) has increasingly been used for the assessment of the electrical properties of molecular scale objects including proteins, DNA, nanotubes and nanowires. However, whilst techniques have been developed for the electrical characterisation of frequency-dependent DEP response, biomolecular study is usually limited to observation using fluorescent markers, limiting its applicability as a characterisation tool. In this paper we present a label-free, impedance-based method of characterisation applied to the determination of the electrical properties of colloidal protein molecules, specifically Bovine Serum Albumin (BSA). By monitoring the impedance between electrodes as proteins collect, it is shown to be possible to observe multi-dispersion behaviour. A DEP dispersion exhibited at 400 kHz is attributable to the orientational dispersion of the molecule, whilst a second, higher-frequency dispersion is attributed to a Maxwell-Wagner type dispersion; changes in behaviour with medium conductivity suggest that this is strongly influenced by the electrical double layer surrounding the molecule
