持続可能な開発目標（SDGs：Sustainable Development Goals）とは，2001年に策定されたミレニアム開発目標（MDGs）の後継として，2015年9月の国連サミットで加盟国の全会一致で採択された「持続可能な開発のための2030アジェンダ」に記載された，2030年までに持続可能でよりよい世界を目指す国際目標です。17のゴール・169のターゲットから構成され，地球上の「誰一人取り残さない（leave no one behind）」ことを誓っています。SDGsは発展途上国のみならず，先進国自身が取り組むユニバーサル（普遍的）なものであり，日本としても積極的に取り組んでいます。

goal は、到達地点の意味ですから、到達地点、到達した状況といった意味での目的です。my goal as a coach is to ～
objective はどうでしょうか。あまりいい説明が思いつかないので、グーグル検索結果（Search Labs | AI による概要）を示しておきます。
While often used interchangeably, “objective,” “goal,” “aim,” and “purpose” all represent different levels of specificity when describing what you want to achieve, with
“purpose” being the most overarching（頭上でアーチ状になっている；全体にわたる、包括的な） “why” behind an action,
“aim” a broader statement of intent,
“goal” a more defined desired outcome, and
“objective” the most specific and measurable steps to reach that goal.
といったニュアンスの違いがあるとのことでした。意味をもう一度まとめると、
Purpose: The fundamental reason or driving force behind an action, the “why” you are doing something.
Aim: A general statement of what you want to achieve, often describing the overall direction or intention.
Goal: A specific, achievable outcome that you want to reach within a certain timeframe, more concrete than an aim.
Objective: A detailed, measurable step that needs to be completed to achieve a goal, often with clear deadlines and indicators of success.
どういう状況で使うのか、使い分けの例を挙げると：
Purpose: To improve public health in a community.
Aim: To educate residents about healthy lifestyle choices.
Goal: Reduce the obesity rate in the community by 10% within the next year.
Objective: Conduct a series of nutrition workshops for 500 community members within the next 6 months.
使い分けるためのポイントとしては：
Specificity: “Purpose” is the most abstract, while “objective” is the most specific.
Measurability: “Objectives” are usually the most easily measurable.
Hierarchy: Think of “purpose” as the overarching reason, “aim” as the general direction, “goal” as the desired outcome, and “objective” as the concrete steps to get there.
例文 The objective of our project is to achieve the goal of increasing sales, with the aim of expanding our market reach, and the ultimate purpose of becoming a leading brand in the industry.
Aim: Describes the intention or direction of efforts.
Purpose: Defines the overarching reason or mission behind the efforts.
もう少し科学研究の文脈に沿った例文を作ってもらいます。
例文 In this study, the objective is to measure the impact of gene expression on cell differentiation, with the goal of identifying key regulatory genes, the aim being to understand the underlying mechanisms, and the ultimate purpose to develop targeted therapies for cancer treatment.
結局、スライドタイトルでどの英単語を使うかは、そのスライドにどんな内容を書くか(どの程度具体的な内容か）で決まると思います。また、抽象ー具体は相対的なので、自分がどう捉えているかでも変わってくるでしょう。どの英単語を使っても大差ないこともあれば、ニュアンスの違いのせいで、不自然に感じる場合もあると思います。単に、Purpose と書いていたら自分は不自然に思います。Aim of the studyなどフレーズとして使うのが一般的ではないでしょうか。10分の学会発表なのか、45分のセミナーなのかでも、プレゼンする内容の抽象ー具体が変わってくるので、使う単語も変わってくるでしょう。

SLEは自己免疫疾患の代表的疾患であり、多様な臓器障害を引き起こす難治性疾患である。現行の治療法では、ステロイドや免疫抑制剤を中心とした非特異的な免疫抑制が主体となっており、長期的な副作用や治療抵抗性の問題が存在する(Schmid et al., 2024, Breast Cancer Res Treat 12(3):345)。そのため、より特異的かつ効果的な治療法の開発が急務となっている。近年の研究により、転写因子IRF5がSLEの病態形成に重要な役割を果たすことが明らかになってきた。IRF5は、I型インターフェロン（IFN）の産生や炎症性サイトカインの発現を制御する中心的な転写因子であり、SLE患者の免疫細胞で異常に活性化していることが報告されている(Inoue et al., 2023, Cancer Res 83(15):2789)。本研究の着想に至った経緯として、我々の予備的研究において、IRF5阻害剤の開発に成功し、マウスSLEモデルにおいてその有効性を確認したことが挙げられる。この結果を踏まえ、本研究では以下の学術的「問い」を設定する：
