RESUMO
INTRODUCTION: The consumption of alcohol, tobacco, and cannabis is a public health problem that impacts the cognitive, social, and emotional development of adolescents. Prevention strategies such as the "Unplugged" program are effective in delaying the progression of daily smoking and episodes of drunkenness among adolescents. "Yo Se Lo Que Quiero" (YSLQQ) corresponds to the adaptation of this program to the Chilean context. This study assesses the acceptability and feasibility of implementing this program to the local reality. MATERIAL AND METHODS: This was a cluster-randomized controlled pilot study conducted on six public schools. All consented students attending 6th, 7th, and 8th grades (n = 1,180) participated in the study. The schools were randomly assigned to one of two conditions in a 1:1 ratio: (1) the "YSLQQ" intervention group (n = 526), and (2) the Control group (n = 654). The program consisted of a 12-hour class-based curriculum based on a comprehensive social-influence approach delivered by a trained facilitator. The acceptability and feasibility were assessed in the intervention group at the end of the intervention using questionnaires answered by students and facilitators. The quality and fidelity of the program were evaluated during the implementation using self-ported surveys answered by the facilitators and the assessment of video-recorded sessions rated by external observers. Finally, a pre-test and a post-test survey assessing past and current substance use and risk and protective factors were conducted before and immediately after the program's implementation. RESULTS: A high proportion of students (49.6%) liked the sessions. 79.2% reported that the YSLQQ helped them learn about the dangers of substances, while 65.8% reported having more skills to avoid substance use in the future. Regarding students' satisfaction with YSLQQ, 62.9% reported being happy or very happy with the program. Facilitators reported implementing the intervention according to the manual in 73.9% of sessions. Regarding substance use, students who participated in the intervention groups reported a significant reduction in drunkenness in the last year and last 30-day prevalence and also a significant reduction in a lifetime and 30-day prevalence of cannabis use when compared with those students in the control group. CONCLUSIONS: Our results suggest that YSLQQ has adequate acceptability and feasibility to be implemented in the Chilean context, and there were promising results in reducing drunkenness and cannabis use. Future research should confirm these results in a larger RCT study. TRIAL REGISTRATION: The trial was registered in ClinicalTrials.gov, NCT04566627; registration date: 01/03/2019.

The interest for pejibaye crops started to grow after the 70s decade, due to the agronomic qualities, ecological, industrials and commercials. The São Paulo State is highlighted as one of the biggest pejibaye growers of the country, most concentrated at Vale do Ribeira. It was objectified with this work to evaluate characteristics of vegetative growth of plants as well as the ideal cutting time for stems in cultivation with different population densities, for the second year of cutting, aiming at the heart-of-palm yield of pejibaye. The experimental design was used in a 2x5 factorial, with treatments with five classes of cutting height (1,60 m, 1,90 m, 2,20 m, 2,50 m and 2,80 m) and two densities of plants (5,000 and 10,000 plants ha-1). The experiment was led on Campus Experimental de Registro UNESPs farm. The analyzes were performed on march 16th and 17th of 2016 and September 01st e 19th of the same year. Stems of pejibaye at cutting height of 2,8 m and harvested in march obtained a larger number of leaves, a larger diameter of the stem in relation to the other heights and larger total amount of heart-of-palm produced. Stems with the same cutting height, but harvested in the month of September, provided greater production of minced hearts-of-palm, slice, thole and total amount of pejibaye heart-of-palm.(AU)
O interesse pela cultura da pupunha começou a crescer após a década de 70, tendo em vista as qualidades agronômicas, industriais e comerciais. O Estado de São Paulo possui destaque como um dos maiores produtores de pupunha do país, sendo a maior concentração no Vale do Ribeira. Objetivou-se com este trabalho avaliar características de desenvolvimento vegetativo das plantas e produtividade de palmito em função do momento de corte das hastes em cultivo com diferentes densidades populacionais, para o segundo ano de corte. O delineamento experimental utilizado foi o de blocos casualizados em esquema fatorial 2x5 e quatro repetições, sendo os tratamentos com cinco classes de altura de corte do estipe (1,60 m, 1,90 m, 2,20 m, 2,50 m e 2,80 m) e duas densidades de plantas (5.000 e 10.000 plantas ha-1). O experimento foi conduzido na fazenda do Campus Experimental de Registro da UNESP. As análises foram realizadas em dois momentos, março e setembro de 2016. Hastes de 2,8 m colhidas no mês de março obtiveram maior diâmetro do caule, número de folhas e quantidade total de palmito produzido. Hastes com a mesma altura de corte, porém colhidas no mês de setembro proporcionaram maior produção de palmito picado, rodela, tolete e quantidade total de palmito pupunha.(AU)
