An image consisting of (m, n) pixels can be seen as a matrix of m × n size. Based on the formula of angles between two subspaces, a pair of angles can be defined between two matrices, by utilizing column spaces and row spaces of the two matrices. The singular values of each matrix can be used to calculate distances. Thus, a distance representation is obtained, and a pair of angles between 2 matrices of the same size.

Pre-eclampsia is a hypertension disorder during pregnancy, significantly affects maternal morbidity and mortality worldwide. A Case-control research was done on 100 pregnant mothers as respondents: 50 case (pre-eclampsia) and 50 control groups (healthy pregnant mothers). Selected case the following characteristics: were patients that visited the Syamrabu Bangkalan Public Hospital; were third-generation Madura natives; aged between 20-40 years old; had a gestational age of over 20mgg; had blood pressure above 140/90mmHg; and single pregnancies. Control had the following characteristics: were healthy pregnant women without pre-eclampsia or chronic hypertension; were third-generation Madura natives; had a gestational age of over 20mgg; aged between 20-40 years; and without pregnancy complications. The results showed of those with PE, 45 had the AA genotype (homozygote) (90%), five had AC (heterozygote) (8%) and one had CC (homozygote) (2%). As for those without PE, 33 had the AA genotype (homozygote) (73.3%), 11 had AC (heterozygote) (26.7%), none had CC (homozygote) (0%). PE and non-PE cases mostly had the AA genotype (homozygote) and A alleles. AT1R 1166 A/C polymorphism was found to be a significant risk factor for pre-eclampsia, while potassium level had no significant effect on it. Meaning further research is needed on different ethnicities and races.

Agro-ecotourism is a tourism development activity in a location with ecological and agricultural advantages, leading to business utilization to generate economic value. Agro-ecotourism in West Java has a selling point in the form of natural potential, agriculture, arts, handicrafts, to the traditional culinary processing typical of the village. This research aims to analyze the sustainability level and the sensitive factors or attributes that affect the level of sustainability of community-based agro-ecotourism in West Java. The study used a survey method on 237 agritourist actors. Data were analyzed using Multi-Dimensional Scaling in the Rapid Appraisal-Tourism technique. The study results show that community-based agro-ecotourism in West Java is quite sustainable (57.07). This study analyzed sustainability through economic, social, cultural, institutional, ecological, and technological dimensions. The social dimension has the highest value because agriculture-based village tourism is carried out in the community. Meanwhile, the lowest value is the technology dimension. The availability of infrastructure influenced the value obtained and means of transportation as well as environmentally friendly farming techniques.

The growth of the fаshion industry in Bаndung, which is increаsing every yeаr, if it is not bаlаnced with the аpplicаtion of digitаlizаtion аnd the use of the lаtest technology, it would be very unfortunаte. Аpаrt from the increаse in the number of internet users, the online shopping style by the community is аlso one of the driving forces for the growth of e-commerce, especiаlly in the midst of the current Covid pаndemic situаtion. This study will exаmine the аdoption of e-commerce technology to sell online in the midst of the Covid pаndemic to fаshion industry plаyers in Bаndung using these vаriаbles: effort expectаncy, performаnce expectаncy, fаcilitаting conditions, sociаl influence, existing hаbits, hedonic motivаtion, and also the price vаlue in the UTАUT2 model. So thаt it cаn show how the contribution of the аdoption of e-commerce technology to the behаviourаl intention аnd use behaviour of the fаshion industry consumers in Bаndung. Our research use quаntitаtive approach, cаusаl research/study with Structurаl Equаtion Modeling (SEM) аnаlysis technique using the SMАRTPLS 3.2.9 softwаre. Reseаrchers chose the аccidentаl sаmpling with а totаl of 400 respondents. Аll exogenous vаriаbles аffect behаviourаl intention by 80.9% аnd 54.9% on use behаviour.

Rice farming households having limited capital do various combinations of the capital to get diversified livelihoods in continuing their lives. The purpose of this study was to analyze the effect of the household capital of rice farmers on livelihood diversification in Indramayu District. Survey method with data sources from 214 rice farming households taken by proportional simple random sampling technique. Data analysis used the partial least square method. The results found that the household capital of rice farmers has a positive and significant effect on the livelihood diversification. Government policy recommendations were determined in order of priority are physical capital with the help of agricultural tools and machinery, natural capital by anticipating climate change, financial capital by increasing support for capital sources, social capital by social networks, and human capital by improving farming skills.

Background: Patients hospitalized in the intensive care unit (ICU) have a higher susceptibility to infections. Respiratory infections are the most common nosocomial infections. Rising antibiotic resistance due to indiscriminate use of antibiotics and poor adherence to standard precaution in healthcare facilities compounds the problem. The main aim of this study is to assess microbial patterns and antibiotic resistance from bronchoalveolar lavage specimens in severe pneumonia patients. Methods: This retrospective study was conducted in an Indonesian tertiary care hospital from January 2016-December 2020. Written and verbal informed consent was obtained prior to bronchoscopy procedures. Patients were enrolled if they had severe community-acquired pneumonia (CAP) according to American Thoracic Society (ATS)/Infectious Disease Society of America (IDSA) criteria, had high-risk hospital-acquired pneumonia (HAP), late-onset ventilator-associated pneumonia (VAP), or pneumonia caused by Coronavirus disease (COVID-19). Respiratory specimens via bronchoscopy were inoculated on general semi-sloid thioglycolate media. Testing for antibiotic susceptibility was done using the disk diffusion method. Results: Two hundred and one patients’ data were analyzed. The majority of patients were males (65,17%) and above 60 years of age. The most common type of pneumonia was CAP (39,3%). Neurologic/cerebrovascular disease was the most common comorbidity (35,32%). Acinetobacter baumannii was the most frequently isolated microorganism. Ampicillin/sulbactam and amikacin were found to yield lower microbial resistance. Conclusion: Combination of ampicillin/sulbactam and amikacin appeared effective as initial empirical therapy in severe pneumonia patients. Further studies are needed to evaluate the feasibility and effectiveness of this combined therapy.

This research aims to develop an inexpensive ocean observation instrument with a project name is NOBEL (Nusantara Oceanography Backdoor Experiment Laboratory)-BOX. The device can be installed on all types of vessels and placed in a specific area to map the water conditions, providing accurate data for managing a marine area specifically to water quality. The principle of NOBEL-BOX is to attach sensors in a container connected to a microcontroller and then measure directly. The method employed includes experimental design, laboratory and field tests, and data evaluation to produce the necessary system and instruments. The design process involves the construction of the instrument and the fabrication of the device. This process includes creating three-dimensional sketches/drawings, designing microcontrollers and data transmission systems, and power capacity. The sensors attached to this device are surface water temperature, air temperature, salinity, dissolved oxygen, pH, and TDS. The testing phase includes data validation, testing of the device in the laboratory, and field testing. The laboratory and field tests showed that the device worked and provided data that can be used to analyze the seawater condition spatially and over time.
