A study to evaluate the effectiveness of planned educational programme on knowledge and attitude regarding psychosocial problems of eating disorders among adolescent girls studying in selected P.U Colleges at Vijayapur

Background: Eating problems are prevalent, with girls more likely to develop issues in adolescence. Concerning indicators include weight fluctuations, altered eating patterns, and excessive physical activity. Outpatient treatment is effective for most, but some may require hospitalization or residential programs for stability and care. Methods: This research adopted an evaluative research approach and employed a pre-experimental (one group pre-test post- test design), and a sample of 60 adolescent girls studying in PU College is recruited through simple random sampling technique. The investigation was conducted at selected PU colleges, Vijayapur. Karnataka, among the adolescents. Results: This study assessed the knowledge and attitudes of adolescent girls in PU colleges in Vijayapur regarding eating disorders. Pretest results showed a majority with moderate knowledge and unfavorable attitudes. Following an educational program, significant improvements in knowledge and attitudes were observed. The findings highlight the effectiveness of targeted interventions in enhancing awareness and promoting positive attitudes. H1: Post-test knowledge scores significantly improved compared to pre-test scores (p<0.05). H2: Post-test attitude scores significantly enhanced compared to pre-test scores (p<0.05). H3: No significant associations were found between knowledge and attitude scores and socio-demographic variables among adolescent girls. Conclusions: In summary, targeted interventions can enhance knowledge and attitudes about eating disorders among adolescent girls in PU colleges. Outpatient treatments and education are crucial for addressing these issues, but more research and interventions are needed to promote awareness and positive attitudes.

Effect of hydrocooling, packaging, and cold storage on the post-harvest quality of peppermint (Mentha piperita L. ) / Efeito do hidroresfriamento e embalagem sobre hortelã-pimenta fresca armazenada em temperatura ambiente e ambiente refrigerado

ABSTRACT The purpose of this study was to assess the effects of hydrocooling and polyethylene terephthalate (PET) perforated and non-perforated packaging on post-harvest quality of peppermint (Mentha piperita L.) leaves stored at 5 and 25ºC. The experiments were conducted using a subdivided parcel layout in a completely randomized design with four replicates. Each parcel used a 2x3 layout (two hydrocooling treatments and three packaging treatments) with subparcels for storage time. The shelf life, chlorophyll content, mass loss (ML), relative water content (RWC), total soluble sugars (TSS), reducing sugars (Red), non-reducing sugars (NRed) and starch of the leaves were determined. Cold storage increased the shelf life of the peppermint by up to 64 times (>15 days). Hydrocooling increased the RWC of the leaves. Plastic packaging was effective in maintaining the RWC. Unperforated packages more effectively prevented ML in the peppermint leaves and prevented the leaves from wilting for a longer period of time. The chlorophyll content of the leaves varied according to the treatment. The soluble sugars and starch levels varied according to RWC. Hydrocooling with the use of non-perforated plastic packages was the most effective method for maintaining the postharvest quality of the peppermint.

RESUMO O trabalho objetivou avaliar os efeitos do hidroresfriamento e da embalagem de politereftalato de etileno (PET) perfurada e não perfurada na qualidade pós-colheita de folhas de hortelã pimenta (Mentha piperita L.) armazenadas em temperatura ambiente e sob refrigeração. Os experimentos foram instalados seguindo o esquema de parcela subdividida, tendo na parcela o esquema fatorial 2x2 (dois tratamentos envolvendo hidroresfriamento e dois tratamentos envolvendo embalagens) e nas subparcelas os tempos de armazenamento no delineamento inteiramente casualizado com quatro repetições. Foi determinada a vida de prateleira, os teores de clorofila, a perda de massa fresca (PM), o teor relativo de água (TRA), os teores de açúcares solúveis totais (AST), redutores (RED), não redutores (NRED) e amido das folhas. O armazenamento refrigerado aumentou em até 64 vezes (>15 dias) a vida de prateleira de hortelã-pimenta. O hidroresfriamento aumentou o TRA das folhas. A embalagem plástica foi efetiva no aumento da vida de prateleira de hortelã-pimenta sendo eficiente na manutenção dos TRA das folhas. A embalagem não perfurada foi mais eficiente na prevenção da PM. O teor de clorofila das folhas variou de acordo com o tratamento. AST, RED, NRED e amido variaram de acordo com TRA nas folhas. O hidroresfriamento juntamente com utilização de embalagem não perfurada foi o método mais eficiente na manutenção da qualidade pós-colheita de hortelã-pimenta.

Influência alelopática de hortelã (Mentha x villosa Huds. ) sobre emergência de plântulas de alface (Lactuca sativa L. ) / Allelopathic influence of mint (Mentha x villosa Huds. ) on the emergence of lettuce (Lactuca sativa L. ) seedlings

Objetivou-se com esse trabalho avaliar a interferência de possíveis efeitos alelopáticos de Mentha x villosa Huds. sobre a emergência de Lactuca sativa L. As atividades foram conduzidas em laboratório, no Instituto de Ciências Agrárias (ICA) da Universidade Federal de Minas Gerais, em Montes Claros/MG. Foram propostos três tratamentos, sendo esses: solo A, coletado em área cultivada com hortelã no horto medicinal do ICA/UFMG; solo B, coletado em áreas adjacentes e, testemunha (papel germiteste).O delineamento experimental foi inteiramente casualizado (DIC), com sete repetições. As variáveis avaliadas foram: porcentagem e índice de velocidade de emergência. Observou-se que a emergência de plântulas de Lactuca sativa foi significativamente afetada pelo solo A (6,95 por cento) se comparada com o solo B (21,71 por cento), representando assim, uma inibição da emergência, ou seja, efeito alelopático da hortelã sobre a emergência de alface. Já o índice de velocidade de emergência (IVE) não diferiu significativamente entre os solos testados.

This study aimed to assess the interference of possible allelopathic effects of Mentha x villosa Huds. on the germination of Lactuca sativa L. The activities were carried out in laboratory, at the Institute of Agricultural Sciences (ICA) of the Federal University of Minas Gerais, Montes Claros, Minas Gerais State, Brazil. The following three treatments were proposed: soil A, collected in area cultivated with mint at the garden of ICA; soil B, collected in adjacent areas; and control (germitest paper). Experimental design was completely randomized (CR), with seven replicates. The evaluated variables were: germination percentage and speed index. The emergence of Lactuca sativa seedlings was significantly affected by soil A (6.95 percent) when compared to soil B (21.71 percent), indicating thus emergence inhibition, i.e. an allelopathic effect of mint on lettuce emergence. On the other hand, the germination speed index (GSI) did not differ significantly between the tested soils.

Influência do substrato e do tamanho da célula de bandejas de poliestireno expandido no desenvolvimento de mudas e produção de calêndula (Calendula officinalis L. ) / Influence of substrate and cell size of expanded polystyrene tray on the development and production of marigold (Calendula officinalis L. ) seedlings

A calêndula (Calendula officinalis L.) é uma planta medicinal anual de origem Mediterrânica que apresenta propriedades antiinflamatórias, antivirais, antigenotóxicas. A propagação desta planta normalmente é feita por sementes, sendo o uso de bandejas de poliestireno uma forma econômica de produção de mudas. Foram conduzidos dois experimentos com o objetivo de avaliar a interferência de dois tamanhos de célula em bandeja de poliestireno expandido (40 cm³ e 12 cm³) e de dois substratos (solo + esterco bovino curtido e substrato comercial tipo Plantmax para hortaliças®) sobre a qualidade de mudas e a produção de calêndula. O delineamento estatístico nos dois experimentos foi em blocos casualizados, dispostos em arranjo fatorial 2 x 2 (dois substratos e dois tamanhos de células) com seis repetições. Os tratamentos, referentes aos tamanhos das células foram bandeja com 128 células (40 cm³ de volume) e, bandeja com 288 células (12 cm³ de volume). Os substratos utilizados foram solo de cerrado + esterco bovino curtido (1:1) e substrato comercial tipo "Plantmax para hortaliças®". Parte das mudas foi transplantada para avaliação da produção de capítulos. Houve diferenças significativas entre os substratos para as variáveis: matéria seca de parte aérea, matéria seca da raiz e matéria seca total. O uso do substrato formulado com solo de cerrado e esterco bovino proporcionou o melhor desenvolvimento das mudas de calêndula. Contudo, os diferentes tipos de substrato e bandejas de poliestireno não influenciaram significativamente a produção de capítulos das mudas transplantadas.

Marigold Calendula (Calendula officinalis L.) is an annual medicinal plant of Mediterranean origin which presents anti-inflammatory, antiviral and antigenotoxic properties. This species normally propagates through seeds, and the use of polystyrene trays is an economic way to produce its seedlings. Two experiments were carried out to evaluate the influence of two cell sizes of expanded polystyrene trays (40 cm³ and 12 cm³) and two substrates (soil + cattle manure and Plantmax® commercial substrate for vegetables) on marigold production and seedling quality. Experimental design in both assays was in randomized blocks, in a 2x2 factorial arrangement (two substrates and two cell sizes), with six replicates. Treatments regarding cell sizes were trays presenting 128 cells (40 cm³) and trays containing 288 cells (12 cm³). The used substrates were cerrado soil + cattle manure (1:1) and Plantmax® commercial substrate for vegetables. Part of the seedlings was transplanted to evaluate capitulum production. There were significant differences among substrates for total, root and shoot dry matter. The use of substrate containing cerrado soil and cattle manure led to the best development of marigold seedlings. However, the different types of substrates and polystyrene trays did not significantly influence capitulum production in transplanted seedlings.
