The Covid-19 epidemic has negatively impacted many industries around the world; the fashion industry is no exception. However, the business activities of the high-end fashion field have found virtual solutions to maintain operations by new technology platforms, which help improve the customer’s access to the fashion brand. This paper identifies digital fashion as the most optimal solution not only in the present time but also further in the future of the fashion industry, by collecting the methods, software and tools that many fashion brands have used since 2020 and predicting that the technology industry will explode in the following years. Through analyzing and synthesizing the effectiveness of the software applications that fashion designers have used, the study presents design trends that use technology as a platform to reality clothes on computer screens, clothes that look real without the use of sewing machines and fabrics. These results provide an overview of how top brands communicate, operate and control the fashion industry in the context of the Covid-19 epidemic. On the other side, it helps expand design knowledge and thinking for countries with a growing fashion industry. In general, digital fashion is a fast, convenient, useful and effective transformation and connection between many fashion departments, design and business in the era of industry 4.0.

T. Nguyen, P. Nguyen, V. T. Tran, D. Pham, L. Benabou
Concrete-Filled Steel Tube (CFST) columns need to be reliably analyzed and estimated under axial compression. This research contributes to solving the above problem by using an integrated Ansys Workbench application, Ansys DesignXplorer. This approach is convenient for academics and industry in the CFST column design because the proposed compressive strength formulas will be established in the parameters’ properties. Correlation analysis and design of experiment (DOE) algorithms help explore the present study and design, includes to optimize and six sigma analysis in the reliability assignment of CFST columns with CFST cross-section dimensions such as 150 mm external diameter, 2.0 to 4.3 mm steel tube thickness and 450 mm column length. The efficiency of this research concept allows selecting specified techniques to axial compression strength of CFST columns primarily in design standards, the use of simulations, and innovative tests using probability values.

Performance of an L-shaped solar chimney with different ratios of the horizontal and vertical portions 水平和垂直比例不同的l型太阳能烟囱的性能
T. N. Huynh, Y. Nguyen
As one of the most common methods for natural ventilation of building, solar chimney has been studied widely in the literature. Various forms of solar chimney have been proposed for enhancing its performance for a specific application, i.e ventilation and/or heating. In this work, we examined performance of an L-shaped comprising horizontal and vertical air channels connected serially by a numerical model based on the Computational Fluid Dynamics (CFD) method. Two different total lengths and gaps of the chimney were tested. The considered parameters included the flow rate, temperature rise, and thermal efficiency. The results show that as the horizontal portion is longer than the vertical one, the flow rate decreases while the temperature rise increases. The variation of the thermal efficiency depends on the ratio between the gap and the total length of the air channel. The findings can help to select suitable configurations of an L-shaped for a specific cooling or heating application.
太阳能烟囱作为一种最常用的建筑自然通风方式,在文献中得到了广泛的研究。人们提出了各种形式的太阳能烟囱,以提高其特定应用的性能,即通风和/或加热。在这项工作中,我们通过基于计算流体动力学(CFD)方法的数值模型研究了由水平和垂直连续连接的l形空气通道的性能。对两种不同的烟囱总长度和间隙进行了测试。考虑的参数包括流量、温升和热效率。结果表明:随着水平段比垂直段长,流量减小,温升增大;热效率的变化取决于间隙和风道总长度之间的比率。研究结果可以帮助选择适合特定冷却或加热应用的l形结构。

Resolving conflict between conservation and promotion heritage of urban architecture in Vietnam (Case study: Hanoi, Dalat, saigon - ho chi minh city) 解决越南城市建筑遗产保护与推广之间的冲突(以河内、大叻、西贡-胡志明市为例)
Do Lenh Hung Tu, Nguyen Thi Phuong Dung, Phung Ba Dong
The conflict between preserving and promoting the value of urban architectural heritage in Vietnam is an objective existence. The problem is how to handle harmoniously to both preserve and promote the best heritage values. Each urban heritage has many inherent challenges faced by itself. It is extreme if you sit still when urban structures are deteriorating and deteriorating day by day. Reconstruction and embellishment of items classified as national monuments or locally ranked require special treatment with the heritage: costly and qualifications. Aesthetic knowledge of architecture and fine arts, at the same time, prudence, sophistication, skill in each skill of art creation, material handling, to not destroy inherent heritage value.
越南城市建筑遗产的价值保护与价值提升之间的冲突是客观存在的。问题是如何和谐地处理,以保护和促进最好的遗产价值。每一项城市遗产都面临着许多内在的挑战。当城市结构日益恶化的时候,如果你坐着不动,那是极端的。被列为国家纪念物或地方文物的重建和装饰需要特殊的遗产处理:昂贵和资格。建筑与美术的审美知识,同时,谨小慎微,精于技艺的每一项艺术创作、材料处理,以不破坏固有的遗产价值。

Extraction optimization of total phenolics from Thai basil (Ocimum basilicum var. thyrsiflora) leaves and bioactivities of the extract 泰国罗勒叶中总酚类物质的提取优化及其生物活性研究
N. Ma, N. Le
The Ocimum basilicum var. thyrsiflora leaves which contains numerous bioactive compounds has been traditionally used as medicinal herbs. Aqueous methanol extract from basil have been found to have blood sugar lowering capacity and can be used to treat patients with diabetes. In this study, different conditions were investigated to extract total phenolic content (TPC) from Thai basil leaves. Response surface methodology using Box-Behnken design was employed to optimize and determine the effects of three independent variables of extraction process, namely sample powder/solvent ratio (1/40 – 1/200 g/mL), extraction time (10 - 60 min) and temperature (45 - 65°C) on the total phenolic content. The results indicated that the selected extraction variables have significant effects on the total phenolic content. The optimal extraction condition was determined as following: sample powder/solvent ratio of 1/139 g/mL, time of 39.4 min and temperature of 51.2°C. At this condition, the total phenolic and total flavonoid contents of the extract were 41.76 ± 0.21 mg GAE/g dry weight and 10.95 ± 0.3 mg RE/g dry weight, respectively. Its antioxidant capacity as 2,2-diphenyl- picrylhyrazyl (DPPH) scavenging capacity was 39.06 ± 1.1%, while its inhibitory capacities against alpha-amylase and amyloglucosidase were 47.80±0.93% and 24.86 ± 1.21%, respectively. As the result, the extract of Thai basil leaves exhibited fairly high antioxidant capacity and enzymatic inhibition capacities as compared to other medicinal plants. Thus, the extract of Thai basil leaves may be used as a source of bioactive compounds for health benefits.
罗勒叶含有大量的生物活性化合物,传统上被用作草药。罗勒甲醇水溶液提取物具有降血糖作用,可用于糖尿病患者的治疗。以泰国罗勒叶为原料,研究了不同提取条件下总酚含量的提取方法。采用Box-Behnken设计响应面法优化并确定提取工艺中粉料比(1/40 ~ 1/200 g/mL)、提取时间(10 ~ 60 min)和温度(45 ~ 65℃)三个自变量对总酚含量的影响。结果表明,所选择的提取变量对总酚含量有显著影响。最佳提取条件为:粉料比为1/139 g/mL,时间为39.4 min,温度为51.2℃。在此条件下,提取液总酚和总黄酮含量分别为41.76±0.21 mg GAE/g干重和10.95±0.3 mg RE/g干重。其对2,2-二苯基-苦基肼(DPPH)的清除能力为39.06±1.1%,对α -淀粉酶和淀粉糖苷酶的抑制能力分别为47.80±0.93%和24.86±1.21%。结果表明,与其他药用植物相比,泰国罗勒叶提取物具有较高的抗氧化能力和酶抑制能力。因此,泰国罗勒叶提取物可作为有益健康的生物活性化合物的来源。

Wilen Melsedec O. Narvios, Y. Nguyen
Solid particles impair the performance of the photovoltaic (PV) modules. The results in power losses that lower the system’s efficiency also decrease the life expectancy of the panel. An Internet of Things (IoT) based system was made to monitor, detect dust accumulation, and a cleaning system that would automatically wipe the dust on the surface of the PV solar panels. Using a specific dust sensor, it detects and monitor the amount of dust in the panel. As the dust accumulated reaches its limit, the cleaning system triggers automatically. The ambient temperature was monitored using the temperature and humidity sensor. The data will be received via internet using the Blynk app. The system will address the panel’s dust accumulation problem as it was considered one of the biggest problems globally regarding solar energy reproduction.
