With the rapid development of Internet communication and digital technologies, government can create and share travel information through social media. The purpose of this study is to understand how tourism attraction is constructed by government departments on the social media and how social media users perceive these tourism attractions. The technique of text corpus was utilized to analyze the posting messages elected from Tainan City Government’s Facebook page─@traveltainan. The research results reveal that 10 types of tourism attraction were identified. In addition, the interactive responses on @traveltainan were also examined in terms of “likes,” “comments,” and “shares.” The findings and suggestions are proposed for future studies and implementations about tourism policy and planning in the local area.

Objective: The aim of this study was to analysis the effect of cultivars on the adaptability of kiwifruit processing to chips while six cultivars of kiwifruit were used as the raw material. Methods: Kiwifruit chips were prepared by the method of vacuum freeze-dried. Sensory evaluation and nine indexes such as the yield of kiwifruit chips, water-soluble pectin, acid-soluble pectin, soluble sugar, total acid content, sugar-acid ratio. ascorbic acid content, hardness and crispness of kiwifruit chips were analyzed. Results: There were significantly differences among yield, nutrient content and sensory indicators in kiwifruit chips while the kiwifruit chips were prepared with different cultivars. Kiwifruit chips with cultivar name "Jinyan" were higher in yield, water-soluble pectin, soluble sugar and hardness of kiwifruit chips, but were lower in total acid content and crispness of kiwifruit chips. Kiwifruit chips with cultivar name "Jinmei" were higher in yield, water-soluble pectin, soluble sugar and ascorbic acid, and were lower in total acid, hardness and crispness of kiwi fruit chips. Kiwifruit chips with cultivar name "Jinyuan" were higher in water-soluble pectin, acid-soluble pectin, bound-pectin, soluble sugar, total acid and ascorbic acid, and were lower in hardness and crispness of kiwi fruit chips. Kiwifruit chips with cultivar name "Jintao" were higher in yield, sugar-acid ratio, ascorbic acid, hardness and crispness of the chips, and were lower in water-soluble pectin and total acid in kiwifruit chips. Kiwifruit chips with cultivar name "Cuiyu" were higher in yield, sugar-acid ratio, crispness of kiwifruit chips, and were lower in acid-soluble pectin, bound-pectin, soluble sugar, total acid and hardness of chips. Kiwifruit chips with cultivar name "Donghong" were higher in yield of kiwifruit chips, acid-soluble pectin, bound-pectin, soluble sugar, sugar-acid ratio and hardness of chips, and were lower in water-soluble pectin, total acid and crispness of chips. Conclusion: The cultivars of kiwifruit had extremely effect on the yield, nutrient content and sensory indicators of kiwifruit chips. Kiwifruit named "Donghong" was considered as the optimal cultivar to be prepared kiwifruit chips by vacuum freeze-drying method.

A SiO2@Au@Polyaniline (SiO2@Au@PAN) system has been successfully fabricated leveraging the synergistic effects of gold nanoparticles (AuNPs) to realize enhanced photothermal performance. The SiO2@Au@PAN exhibited strong near-infrared (NIR) absorbance, excellent photothermal conversion efficiency, good dispersibility, and outstanding photostability. The SiO2 nanospheres as the template provided numerous binding sites for coating of AuNPs. Subsequently, aniline was grafted onto SiO2 to form PAN, which further facilitated the growth of AuNPs. The high efficiency of electron transfer from PAN to AuNPs was utilized to enhance the photothermal performance, resulting in a photothermal conversion efficiency of 41.47%. Additionally, the effects of SiO2 with different sizes on the anchoring of AuNPs and the impact of aniline with varying concentrations on the morphology and photothermal properties of the materials were investigated. Finally, we verified the photothermal therapeutic (PTT) effect of SiO2@Au@PAN at cellular level, with results demonstrating effective destruction of cancer cells. This work may provide an approach for establishing a multi-component PTT platform based on the synergistic effects of AuNPs, holding significant potential for biomedical and biochemistry applications.

Purpose: This paper aims to explore a new method for efficient mining of iron ore resources, focusing on the effect of the double sublevels parallel mining method in improving mining efficiency and resource recovery rate,and analyze the safety and stability in the mining process through specific cases. Method: Taking an iron ore mine in Anhui province as the research object, the paper innovatively put forward the double sublevels parallel mining method. By using FLAC3D numerical simulation software, a typical stope numerical model with a size of 50 mX 15 mX 120 m (length, width and height)is constructed to simulate the mining process of double sublevels parallel mining. Result; The stress concentration at the bottom of the goaf and host rock on both sides of the stope increased significantly after the excavation of the double-sublevel stope. The goaf roof has significant displacement, with the maximum displacement reaching 1.2 m. The maximum displacement of the side is 0. 8 m. Further analysis shows that the potential failure mode of host rock is mainly shear plastic failure. Conclusion; The double sublevel parallels mining method has significant advantages in improving the efficiency and resource recovery of iron ore mining. [ABSTRACT FROM AUTHOR]

As a special thinning method, crop tree release (CTR) has a beneficial effect on forest environments and structures by changing forest light, heat, and water. However, the impact of CTR on underground biodiversity remains unclear. Therefore, we analyzed the composition, diversity, and metabolic footprints of soil nematode communities under three CTR (100, 150, and 200 trees [ha.sup.-1]) treatments, as well as a no CTR treatment, in Pinus massoniana Lamb. plantations. The results showed that CTR increased the density of soil nematodes (P < 0.05), the number of omnivore-predator nematodes (P < 0.05), and the diversity (H') of nematodes (P < 0.05) and enriched the food web structure of soil nematodes. In the medium CTR density treatment (150 trees [ha.sup.-1]), the nematode density and diversity (H') were the highest (P < 0.05), the number of omnivore-predator nematodes was also the highest (P < 0.05), and the enrichment index and structure index values of the soil nematodes reached the maximum at the depth of 0-10 cm (P < 0.05). Our results indicated that the community structure of soil nematodes became more stable and mature after CTR, which may be attributed to the changes of soil condition, especially soil organic matter, and plant diversity indirectly. Key words: disturbance, Pinus massoniana, soil environment, soil nematode community, trophic groups. En tant que methode speciale d'eclaircie, le degagement des arbres d'avenir (DAA) a un effet benefique sur la structure de la foret et le milieu forestier en modifiant les conditions de lumiere, de temperature et d'humidite. Cependant, l'impact du DAA sur la biodiversite souterraine est encore nebuleux. Par consequent, nous avons analyse la composition, la diversite et l'empreinte metabolique des communautes de nematodes du sol dans trois traitements de DAA (100,150 et 200 tiges [ha.sup.-1]), ainsi qu'un temoin non traite dans des plantations de Pinus massoniana Lamb. Les resultats montrent que le DAA augmente la densite des nematodes du sol (P < 0,05), le nombre de nematodes predateurs et omnivores (P < 0,05), la diversite (H') des nematodes (P < 0,05) et qu'il enrichit la structure du reseau trophique des nematodes du sol. Dans le traitement de DAA avec une densite moyenne (150 tiges [ha.sup.-1]), la densite et la H' des nematodes etaient les plus elevees (P < 0,05), le nombre de nematodes predateurs et omnivores etaient aussi le plus eleve (P < 0,05) et les valeurs de l'indice d'enrichissement et de l'indice de structure des nematodes du sol atteignaient le maximum a une profondeur de 0-10 cm (P < 0,05). Nos resultats indiquent que la structure de la communaute de nematodes du sol est devenue plus stable et plus mature apres le DAA, ce qui peut etre attribue aux changements dans la condition du sol, plus particulierement la matiere organique dans le sol et indirectement la diversite de la vegetation.
