Diversity of birds in Mihara Campus across four seasons
Get PDFapplication/pdf三原キャンパスに着任した 2013 年から，キャンパスで見て，あるいは声を聞いて種類を同定できたものについて，日時，数，場所などを記録することを始めた。この中には，キャンパス上空を飛び回るだけで構内には降りなかった鳥，研究室の窓から見える沼田川に居た鳥も含まれる。そして，常勤教員としての勤務最終年の2023 年までの間に 38 種を確認した。これらの鳥は，ほぼ年間を通して見られる鳥（イソヒヨドリなど），夏または冬の渡り鳥として飛来する鳥（キビタキやジョウビタキなど），あるいは渡りの季節に一時的に立ち寄りすぐに移動する鳥の 3 グループに大別された。このような豊かな鳥種の飛来には三原キャンパスの立地条件が強く関与していると考えられた。Since starting my position at the Mihara Campus in 2013, I have been recording the observation date, number, and location of various birds on campus, including those flying over the campus without landing and those seen from the lab windows near the Nuta River, that I could identify by sight or song/call. By the end of my tenure in 2023, I had identified 38 bird species, which can be categorized into three main groups: those that can be observed throughout the year (e.g., Blue rock thrush), summer or winter migratory birds (e.g., Narcissus flycatcher and Daurian redstart), and those that briefly stop on campus during migration and subsequently continue their journey. I believe that the rich diversity of bird species recorded on campus is strongly influenced by its geographical location and environment.departmental bulletin pape

Nutritional Status, Dietary Habits, and Subjective Fatigue Symptoms Among Female University Students During the COVID-19 Pandemic
Get PDF女子大学生の非コロナ禍（2018・2019年）とコロナ禍（2020・2021年）における栄養素等摂取状況・食習慣・疲労自覚症状の比較を行った。
非コロナ禍に比べ，コロナ禍の女子大学生は，栄養素等摂取量について食事摂取基準を用いて評価したところ，脂質及び炭水化物エネルギー比は基準値内の者が少なかったが，カリウム，マグネシウム，リン，鉄，ビタミンＡ，ビタミンＤ，ビタミンＢ1，ビタミンＢ2，ビタミンＢ6，ビタミンＢ12，ビタミンＣ，食物繊維は，基準値内の者が多かった。また，総じて食態度・食意識が良好で，食事作りの頻度が高く，食の外部化が抑制されていた。さらに，疲労自覚症状の座りたい，眠い，横になりたい，あくびがでる者の割合が少なかった。家庭にいる時間が増加し，時間的ゆとりができたことが，食事内容を良好にし，疲労自覚症状の低下につながったのではないかと示唆された。Nutritional status, dietary habits, and subjective fatigue symptoms of female university students were compared before the coronavirus disease 2019 (COVID-19) pandemic (2018-2019) and COVID-19 pandemic (2020-2021).
In this study, data of female third-year university students before (n=49) and during (n=54) COVID-19 pandemic were analyzed. A dietary survey was conducted using weighed dietary records for three consecutive weekdays to calculate nutrients and determine the average daily nutrient intake. A self-administered questionnaire was used to investigate dietary habits and subjective fatigue symptoms.
Evaluation of Dietary Reference Intakes for Japanese (2020) revealed that fewer female university students consumed lipid and carbohydrate energy ratios within the reference ranges during the COVID-19 pandemic than before the COVID-19 pandemic. However, students were more likely to consume potassium; magnesium; phosphorus; iron; vitamins A, D, B1, B2, B6, B12, and C; and dietary fiber within the reference ranges during the pandemic than before the pandemic. Overall, the dietary attitudes and awareness were good, the frequency of food preparation was high, and the frequency of outsourcing of meals was reduced. Furthermore, the incidence of subjective fatigue symptoms, such as desiring to sit down, feeling sleepy, desiring to lie down, and yawning, was low.
These findings suggest that the increased time spent at home and the resulting free time led to improved dietary habits and reduced subjective fatigue symptoms.departmental bulletin pape
