作者： tran huu Nghi nguyen Quynh thu tropenbos Viet Nam 149 Tran Phu Street Hue City Thua Thien Hue Province Viet Nam

this paper aims to analyze and evaluate a model of forest conservation and management of ethnic minority (or indigenous) people in central Vietnam, often referred to as the spiritual forest. these forests, called sacred forest or ghost forests by the ethnic minority people in thua thien Hue province, have existed for a long time among forest residents. However, they have recently declined, both in quality and quantity, due to various factors, including changes in society, economy, environment, and perception, among other reasons. Based on research conducted in A Luoi district, thua thien Hue province with household interviews, group discussions, and field surveys, we find that spiritual forest retains religious and human significance. they are also often among the last remaining natural forests left due to deforestation by human activities. the research results indicate challenges that conservation of spiritual forest may face, while giving recommendations derived from communities for sustainable forest development and conservation in the region.

Objective: Botulinum toxin type A is frequently used to treat crow's feet lines. However, the optimal dose and injection sites are still controversial. the objective of this study was to compare the efficacy of different botulinum toxin type A injection patterns for the treatment of crow's feet. Methods: this single-center, retrospective, clinical study was conducted at the National Hospital of Dermatology and Venereology from July 2020 to December 2020. Data on 60 patients with crow's feet were collected and divided into 2 groups (3- or 4-point intramuscular injection) according to the intramuscular injection technique the patients received. the treatment efficacy was assessed based on the changes in the Crow's Feet Grading Scale score at 1, 4, and 16 weeks after treatment. Repeated measures analysis of variance was used for the assessment of changes in scores over time between the two groups. Results: After treatment, the average Crow's Feet Grading Scale score was significantly decreased compared with the pretreatment score at all timepoints (1, 4, and 16 weeks) in both states (dynamic: For 3-point intramuscular injection technique, 1 week: 1.90 ± 0.71 vs. 2.97 ± 0.56; 4 weeks: 1.87 ± 0.68 vs. 2.97 ± 0.56; 16 weeks: 2.60 ± 0.67 vs. 2.97 ± 0.56.
