Nghia Dan is a mountainous district in the northwest of Nghe An province, with potential for agricultural development, especially high-tech agriculture. The survey results in Nghia Dan district show that agro-tourism has initially developed based on the diversity of agroecosystems, including planted forest ecosystem, perennial tree ecosystem, field ecology, and water surface ecosystems. The values of the agro-ecosystem have been exploited and created tourism products such as resorts, and experiences. However, this economic activity still has no specific planning and orientation; agricultural products of high quality but have not yet confirmed the brand; Tourism products are attractive but have not yet made a difference and diversity. On the basis of analyzing the current situation, this study has proposed 5 groups of solutions to develop agricultural tourism in Nghia Dan district, Nghe An province.

In primary school, the application of STEAM in teaching Science has many advantages because teachers are comprehensively trained in the fields of natural sciences and arts. In fact, the biggest difficulty for primary teachers when applying STEAM education is the source of STEAM education materials that are suitable for topics and how to use learning materials to design teaching activities effectively. Therefore, teaching materials on the topic of Matter, Energy in Science subject 4 were developed, including 09 STEAM products and 09 illustrated lesson plans using STEAM products. The results of a pedagogical test with 30 teachers show that the designed STEAM products are effective and feasible in implementing teaching in practice. The STEAM products with implementation suggestions in illustrated lesson plans will provide rich learning resources, help teachers easily implement in practice, and contribute to realizing the goals of the Science program (2018) in primary school.

Introduction: Port-wine stains (PWS) are capillary malformation affecting 0.3% to 0.5% of the population. In Vietnam, the dermoscopic features of PWS have not been systematically studied.Objectives: The aim of this study was to analyze the dermoscopic images of 148 patients with PWS. Methods: 148 cases with PWS were analyzed basing on dermascopic images.Results: The most common vascular images were dots or globules vessels (76.4%) and linear vessels (68.9%). Sausage-like vessels and whitish veils were more common in the group of patients aged older than 18 years or with purple type of PWS. For all the dermoscopic features of PWS, excluding linear vessels, there were no significant differences between lesions located in the central facial area and peripheral facial area (p > 0.05). Compared with the peripheral facial lesions, linear vessels were more common in central facial lesions (p < 0.05). Conclusion: Dermoscopy may provide very useful clinical information before laser treatment of PWS. The vascular manifestations of PWS determined by dermoscopy may correlate with age, colour, location and response to laser treatment.
