Organic conversion tea farms can have comparable economic benefits and less environmental impacts than conventional ones-A case study in China.

Lack of experience concerning the organic conversion period and its associated challenges have made it difficult for conventional farmers to convert to organic farming. In this study, using a combined life cycle assessment (LCA) with data envelopment analysis (DEA) approach, we investigated farming management strategies, and environmental, economic, and efficiency impacts of organic conversion tea farms (OCTF, N = 15) compared to conventional (CTF, N = 13) and organic (OTF, N = 14) tea farms in Wuyi County, China for a year-round (2019). We found that the OCTF reduced agricultural inputs (environmental impacts) and applied more manual harvesting (increased added value) to pull through the conversion period. According to the LCA results, OCTF showed a similar integrated environmental impact index compared with OTF but significantly (P < 0.05) lower than CTF at both midpoint and endpoint levels. In terms of economic assessment, OTF showed the significantly highest total revenue (18.7 thousand $ ha-1 yr-1) and profit (13.7 thousand $ ha-1 yr-1) (P < 0.05) among the farm types. In contrast, OCTF and CTF did not show significant differences in relation to these economic indicators (P > 0.05). The total cost and cost-profit ratio did not show significant differences among the three farm types. Considering the DEA analysis, there were no significant differences in the technical efficiency of all farm types. However, the eco-efficiency of OCTF and OTF was significantly higher than that of CTF. Therefore, conventional tea farms can survive the conversion period with competitive economic and environmental benefits. In this regard, policies should promote organic tea cultivation and agroecological practices to enhance the sustainable transformation of tea production systems.

The impact of education regarding the needs of pediatric leukemia patients' siblings on the parents' knowledge and practice.

A study was undertaken to determine the effect of educational intervention on parents' knowledge and performance of the social needs of the healthy siblings of the pediatric leukemia patients. Inadequate care and attention to siblings of pediatric leukemia patients might result in psychosomatic disorders. Parents' knowledge on prevention of such disorders is of great importance. The study proposed to determine the effects of educational intervention concerning parents. Sixty parents of pediatric leukemia patients entered this study. The subjects were selected using convenient sampling method and were randomly categorized into 2 groups: experimental and control. Data were collected before, 1 hour after, and 2 months after the intervention, using a questionnaire. The educational program was arranged in 3 sessions, each lasting 45 to 60 minutes using group discussion and lectures for the parents of the experimental group. Then, the parents were instructed individually, if necessary. The mean scores of the parents' knowledge in the experimental and control groups before the intervention were 5.8 and 6.2, respectively. One hour after instruction, the mean rose to 12.8 and 6.4, and 2 months later to 13.3 and 6.5 (p < .00l). The family performance of 87.2% of the parents in the experimental group and 36.4% of the control group toward the siblings of the sick child was appropriate 2 months after the intervention. Therefore, educational intervention increased the knowledge of the parents of pediatric leukemia patients about the needs of the healthy siblings and how to meet them. It is recommended that educational programs be arranged for parents so that the quality of life in the healthy children can be improved.
