Abstract
The objectives of this study were: (1) to analyze the ratio of the time required for the roughing process of making a pocket (pocket) from several different strategies for the roughing process, and (2) to analyze the wear of cutting tools for the roughing process of making a pocket from several kinds of roughing cutting method. The research method used was experiment. The materials used are the work piece of mild steel (ST37) and the cutting tool HSS End mill with a diameter of 10 mm with 2 flutes. The machine used was a CNC milling machine and the software used was Master Cam X7. Retrieval of data using a built-in time-measuring instrument, vernier caliper, micrometer, and a digital micrometer with a magnification of 600x to 1000X. Data were analyzed by comparing the time required for each cutting method (8 kinds of methods) on CADCAM and the time on the actual CNC milling machine. The results showed: the fastest time required for roughing the pocket size 80 mm x 80 mm in 6 mm was the zigzag cutting method with straight-in feed (41 minutes 46.68 seconds in the CAM simulation and 42 minutes in machining using a CNC Milling machine), and the longest time is the true spiral cutting method with a ramping in-feed (62 minutes 20.59 seconds in the Master Cam X7 simulation and 62 minutes 21 seconds in the machining process using a CNC Milling machine). The wear of tools for the zigzag cutting method is greater than the true spiral cutting method. The optimization of the pocket making process in a CNC milling machine is calculated based on time and wear, if machining time is the goal, the zigzag cutting method is chosen and if the durability of the cutting tool is the goal, the true spiral cutting method is chosen.

Authors: Purwanto  , Pardjono  
Published: December 2020

Abstract
The application of electronic instrument technology to the health sector requires more detailed quality assurance and is guaranteed in the use, maintenance, repair and/or development of medical instrument devices. Improving the quality and quantity of medical instrument needs to be supported by an increase medical instrument personnel. This research was conducted to examine more about Indonesian medical/electromedical instrument personnel, specifically at vocational high school level in 2020 in an effort to overcome the challenges of the development of instrumental technology in the health sector. The lack of medical instrument personnel must be completed immediately without leaving its quality. Currently, there are regulations regarding the implementation of medical instrument education at the vocational high schools level, but vocational high schools are still constrained by regulations regarding the minimum qualifications for medical instrument education in the applicable regulations. This condition causes vocational high schools to date to have not implemented competency in medical device expertise even though it has been mapped on the spectrum of ministries. In fact, regulations serve as guarantees of operation quality, guarantee of competency criteria, guarantee of work quality, and guarantees for medical instrument personnel.

Abstract
The consumption of natural resources in the world is increasing. People consume a lot of energy in daily products, such as air and water, cause soil pollution, consumption of natural resources, and the Kaxabu Niumian tribe from a natural pollution-free environment the current excessive development and disintegration of agricultural waste materials. Therefore, it is necessary to understand and promote the entire educational process of new environmental protection technologies. Through the learning of school science and technology education, everyone can inspire ideas, starting from the community and school’s environmental education, making products that do not harm the environment, and continue to operate the environmental technology market through technology to improve the living environment. The material used in this product’s design is made of natural bamboo or environmentally friendly PVA material shared in the community, so there is almost no burden on the environment. The principle of use will be made through diversified geometric shapes and high-pressure forming of customized shapes. Starting from elementary school education, the primary school students collect water drops on the coaster to become a small potted plant. The water resources are recycled, and the coaster has new functions. This product design principle is taught as a whole set of environmental protection and sustainable engineering methods. The ultimate goal of this research is to integrate technology into education to understand the use of environmentally friendly materials in life, achieve innovative and sustainable energy technologies, and promote environmental awareness.

Abstract
The ready to wear clothes are developed through two stages, namely clothes designing and producing based on Martello Fort. The process of designing starts with first, the designing process which includes studying the references (idea, style, look), constructing the mood board, sketching, and designing motif. Then, producing which includes: a) preparation stage involving creating the work design, measuring the size, making the 1:4 scale pattern and the large pattern, designing the material, and estimating the product price; b) implementation stage involving creating the abstract motive using tie-dye technique, placing the pattern on the materials, cutting, adding stitching lines, basting stitching and sewing; and c) evaluation stage involving evaluation process I, evaluation process II, and final evaluating of the result. The result of the study is in the form of design of ready to wear abstract motive clothes inspired by Martello Fort. The design has a T silhouette consisting of three pieces, namely: a dress, obi belt, and jacket. The production of ready to wear clothes is not as simple as what it seems since this high-quality concept has an elegant and edgy design. The clothes are targeted for fearless urban teenagers within the middle and upper classes because most of these classes are interested in high-quality products and trend changes.

Published: December 2020

Abstract
The Seediq, who possessed superb weaving skills, was forced to move to Chuanzhong Island (Qingliu tribe) after the Wushe incident in the 1930s. The Japanese banned weaving, coupled with the rapid development of the textile industry at that time, leading to the ramie weaving culture disappearing in the tribe for nearly 50 years. Therefore, this research will combine the weaving patterns of the Seediq tribe with fashion design through design, a fusion of traditional and modern design elements, and give the work unique cultural creativity and fashion flavor. In the hope that through design education, we will learn about tribal products and permanent Continue the value of the business and circular economy, create a tribal fashion culture, complete a series of innovative design works of the Seediq, and achieve the research purpose of sustainable engineering and technology.

Abstract

BACKGROUND
Angiotensin-converting enzyme 2 (ACE2) has been identified as the entry receptor for coronaviruses into human cells, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19). Since hypertension (HT) is a leading comorbidity in non-survivors of COVID-19, we tested for association between ACE2 gene and HT in interaction with specific pre-existing conditions known to be associated with COVID-19 severity.

METHODS
Genetic analysis of ACE2 gene was conducted in French-Canadian (FC) and British populations.

RESULTS
In FC individuals, the T allele of the single nucleotide polymorphism rs2074192 of ACE2 gene was a risk factor for HT in adult obese males [odds ratio (OR) = 1.39, 95% confidence interval (CI) 1.06–1.83)] and even more so in obese males who smoked (OR = 1.67, CI: 1.24–2.55), but not in lean males, non-smoker males or females. The T allele was significantly associated with severity of HT and with earlier penetrance of HT in obese smoking males. Significant interaction between the T allele and obesity was present in both sexes. The association of ACE2 (rs233575) genotype with blood pressure was also seen in adolescents but the interaction with obesity was present only in females. Several variants in ACE2 gene were found to be associated with HT in obese, smoking males in British individuals of the UK Biobank. In addition, we observed more severe outcomes to COVID-19 in association with ACE2 risk alleles in obese, smoking males.

CONCLUSIONS
This is the first report that ACE2 variants are associated with earlier penetrance and more severe HT and with more severe outcomes of COVID-19 in obese smoking males.
