論文的Abstract部分到底該怎樣寫?

Abstract是論文的縮略版或縮寫，通常在文章的開頭部分出現。它概括了主體的內容，例如背景、主題/問題、方法、結論和意義。因此，撰寫高質量的Abstract對于吸引讀者并提高論文被引用的機會非常重要。本文將介紹如何撰寫一篇優秀的Abstract。

確定主題：首先需要確定論文的主題，然后根據主題來確定Abstract的結構和內容。

突出重點：在Abstract中需要突出論文的重點，例如研究目的、方法、結果和結論等。這些重點應該是整篇論文的核心，也是讀者最感興趣的部分。

簡明扼要：Abstract需要簡明扼要地概括論文的主要內容，不要過多地涉及細節。一般來說，Abstract應該在150-250個單詞之間。

語言簡潔：Abstract需要使用簡潔明了的語言，避免使用過于復雜的詞匯和句子。同時，還需要注意語法和標點符號的正確使用。

格式規范：Abstract需要符合學術期刊的要求，包括字數限制、段落結構和標點符號等方面。不同的期刊可能有不同的要求，因此需要仔細閱讀期刊的Instructions for Authors(作者指南)。

Title: The Effects of Exercise on Mental Health in Elderly Patients with Dementia

Background: Dementia is a common disorder that affects millions of people worldwide. It is characterized by memory loss, confusion, and difficulty with everyday activities. Exercise has been shown to have numerous benefits for physical health, but its effects on mental health in patients with dementia are not well understood.

Objective: The aim of this study was to investigate the effects of exercise on mental health in elderly patients with dementia. Specifically, we aimed to determine whether exercise could improve mood, reduce anxiety and depression, and enhance cognitive function in patients with dementia.

Methods: A total of 60 patients with dementia were randomly assigned to either an exercise group or a control group. The exercise group participated in daily aerobic exercise sessions for six weeks, while the control group did not receive any additional treatment. Participants in both groups completed assessments of mood, anxiety, depression, and cognitive function before and after the intervention period.

Results: The exercise group showed significant improvements in all measures compared to the control group. Specifically, participants in the exercise group had lower levels of anxiety and depression and improved mood scores compared to those in the control group. Additionally, exercise appeared to have a positive effect on cognitive function in patients with dementia.

Conclusion: Our findings suggest that exercise can be an effective intervention for improving mental health in patients with dementia. Further research is needed to determine the optimal type and duration of exercise interventions for this population.
