なぜ急に変更したかといいますと，今年度から茨城大学では教員の研究組織「学野」と教育組織「学部」を明確に分けたことが原因になっています．実は今までも研究組織として農学野，教育組織として農学部と一応違いはあったのですが，実質的に一体運用されていました．今年度から阿見キャンパスにいる教員の研究組織は応用生物学野，教育組織は農学部になっています．これで日常的な教育研究業務に大きな違いが出るわけではないのですが，組織としては一応分離するということのようです．その結果，研究室ウェブサイトは文字通り研究のためにあるので，従来の農学部のドメイン agr ではなく lab ドメインを使うということになったようです．]]>研究室セミナー & 5/29-6/14 の輪読 研究室の行事輪読2024-06-16T18:22:49+09:00https://seibutsuseigyo.lab.ibaraki.ac.jp/blog/files/d68ed278b41a382cd492fce5c9c48a5f-145.html#unique-entry-id-145https://seibutsuseigyo.lab.ibaraki.ac.jp/blog/files/d68ed278b41a382cd492fce5c9c48a5f-145.html#unique-entry-id-145の研究室セミナーの文献紹介の担当は化学生態学研究室の修士課程学生で，以下の論文を報告しました．

生物制御化学研究室では，修士課程修了生 1 名，学部卒業生 1 名です．二人とも進学はしませんので，研究室を離れて 4 月からは新社会人（たまたま今年は二人とも公務員）になります．大学生活や研究室での修論・卒論研究の経験を活かして，社会人としても大いに活躍してくれることを期待しています．

3/15（水）2E03-06 ○村田 悠夏、鳥井 潤一郎、戸嶋 浩明、長谷川 守文（茨城大農）
ホウレンソウ葉のフラボン型ファイトアレキシン

この研究は昨年修士課程を修了した鳥井君の研究を今年の卒論学生の村田さんが引き継いだ仕事です．オンライン開催でしたので，発表は事前に動画を作成してアップロードしたものをオンデマンドで視聴してもらい，学会当日は Zoom のブレイクアウトルームで質疑応答を行うという形式でした．私自身は裏で別の発表の進行役というのを担当していたので，村田さんの質疑応答は聞けませんでしたが，30 分間の質疑応答時間では多くの質問をもらえたそうです．なかなか的確に答えるのは難しかったようです．しかし，卒業直前に良い経験となったと思います．

そういう問題を解決するという意味もあって，2024 年 4 月から茨城大学では従来の 90 分授業を 105 分授業に変更することが決定されています（令和６年度からの授業時間の変更について）．これにより今までの 15 回+期末試験が 13 回+期末試験に変更になるため，授業のスケジュールに余裕を持たせられるようになることが期待されています．しかし，その代償として一コマの授業がかなり長時間になってしまうので，教える立場としては授業をより一層工夫しないと 90 分でも飽きられてしまいがちなのに，さらに学生に飽きられてしまいそうです．また，5 講時終了は 18:45 とかなり遅い時刻になってしまいます．

長谷川が担当している二年生向けの科目「一般化学 II」では今年度から通常の期末試験期間の一週間前に期末試験を実施し，期末試験の時間帯に期末試験の振り返りの授業を行うやり方にしました．大学では期末試験を受けたら後は野となれ山となれという感じの授業がほとんどですが，本来はできなかった問題を復習することが重要だと思います．

学生対象の新型コロナウイルスワクチンの職域接種は今週で 2 回目が完了しました．モデルナ製ワクチンは 2 回目の副反応がなかなか厳しいので，研究室の学生たちも接種翌日はダウンしていたようです．私（長谷川）は茨城県の大規模接種会場でモデルナ製ワクチンの接種を 7, 8 月に受けましたが，やはり 2 回目接種の翌日は 38.6 ℃ まで体温が上がってかなりきつかったです．まあ寝てれば熱は下がるので，コロナにかかることを思えば，どうということはないのですが．

幸か不幸か大学は新型コロナウイルス感染者クラスターの発生で，5/31 まで学生は入構禁止で授業は全て遠隔授業という対応をとっていますので，この爆破予告の影響は最小限ですみそうです．しかし，教育学部附属の幼稚園，小学校，中学校，特別支援学校は休校になってしまいましたので，通っている子供達やその保護者の方たちには多大な迷惑（子供は大喜びかも？）がかかってしまいます．
また，茨城大学は水戸，日立，阿見の 3 キャンパスだけでなく，東海サテライト，水戸駅南サテライト，水圏環境ステーション（潮来），五浦美術文化研究所（北茨城），宇宙科学教育研究センター（高萩）と茨城県内各所に拠点がありますが，今回の予告には対象施設は含まれていないらしく，これらの拠点全てで対応しなければなりません．
こういう爆破予告（おそらく威力業務妨害）の検挙率がどの程度かは知りませんが，この手の犯罪を防止するためには「そんなことして捕まったら割りに合わない」と思わせるしかないように思います．茨城県警に頑張ってもらって是非検挙して欲しいところです．

授業は全て遠隔授業になり，学生実験や実習は休講，大学に来て行う研究活動は生物や機器の管理などの必要最小限のことしかできなくなりました．生物制御化学研究室も植物の水やりを除いて皆自宅での研究しかできなくなりました．我々の分野は実験科学ですから，自宅での研究は関連論文を読んで情報収集したり，論文の書けるところを書いたりしかできない（これをできる時にやっておくのは重要ですが）ので，研究活動には大きなブレーキがかかってしまいました．
今後これ以上の感染者が出ずに，この緊急事態措置が 5/31 で終わってくれることを祈るしかありません．

今日は生物制御化学研究室と化学生態学研究室合同で，所属する 3 名の修士 2 年生の中間発表会が開催されました．このご時世ですので，発表は Microsoft Teams を用いたオンラインでの開催となりました．あと一年近くあるというように感じていても，修論研究のために実質的に実験を進められるのは半年ちょっとなので，ここから修論提出までは案外あっという間に過ぎてしまいます．修論だけではなく，できれば原著論文の投稿ができるように残りの時間を頑張っていただきたいと思います．]]>生物制御化学研究室ウェブサイトリニューアルが概ね完了ブログ・HP2021-05-01T18:24:57+09:00https://seibutsuseigyo.lab.ibaraki.ac.jp/blog/files/8d5cba1bd384d0d248a2d9439e62e887-5.html#unique-entry-id-5https://seibutsuseigyo.lab.ibaraki.ac.jp/blog/files/8d5cba1bd384d0d248a2d9439e62e887-5.html#unique-entry-id-5サイト管理を BiNDup から RapidWeaver に移行した生物制御化学研究室のウェブサイトのリニューアルが概ね完了しました．もちろん，これからも更新して内容を充実させていく必要はあるのですが，現時点でリニューアル前とほぼ同等以上の情報をアップできていると思います．

作成環境は RapidWeaver 8，定番の有料プラグインである Stacks 4（YourHead Software），レスポンシブウェブデザイン（PC とスマホなどの違いに応じて表示を変えるもの）対応の比較的シンプルでうるさくない有料テーマの Mirage（ThemeFlood）です．サイトのバナー画像は RapidWeaver から直接アクセスできるフリー画像集サイト Unsplash から取ってきた水田の写真です．RapidWeaver は単体だけではできることが結構限られているのですが，サードバーティーのアドオンやテーマの開発が結構活発に行われているようです．

RapidWeaver では Markdown を使ってコンテンツを書けるので，このウェブサイトでも基本的には Markdown を使って各ページの内容は書いています．もちろん Styled Text も使えるのですが，Markdown で書く方が慣れれば楽そうですし，書き出されるコードも綺麗なようなので，当面は Markdown 中心でいこうと思います．ただし，このブログページは Styled Text で書いています．どうも標準の RapidWeaver ブログエディタでは Markdown は使えないようです．

研究室のウェブサイトの構成は基本的に BiND 時代のものを踏襲していますが，教員の担当授業を紹介していた「教育内容」のページはメンバー紹介のページに統合しました．

現在気が付いている問題点としては，Stacks を使って，PC・タブレットは 2 カラム表示，スマホは 1 カラム表示設定にしているメンバー紹介とアクセスのページが大画面スマホ（iPhone 12 Pro Max など）だと 2 カラム表示のままで，スマホ対応の 1 カラム表示に切り替わらないという点があります．どうも，横幅 400 ピクセル以上ある端末は PC・タブレットとして認識されてしまうようです．

ウェブサイト構築・管理用のソフトというのは，結構栄枯盛衰が激しく，Adobe からだけでも古くは PageMill，GoLive，Contribute，最近は Muse というもはや最新版がリリースされなくなったソフトが死屍累々です．Windows ユーザーなら，IBM からジャストシステムへ移った定番のホームページ・ビルダーがありますが，私はマックユーザーなので，BiND に代わるソフトをどうしようかと思っていました．Dreamweaver は流石にオーバースペックなので，マックユーザーには古くから知られている Realmac Software の RapidWeaver 8 を使うことにして，BiND で作ったサイトを RapidWeaver に引っ越しました．移行ツールのようなものはなく，概ね手動で行ったので，しばらく時間がかかってしまいましたが，やっと公開できることになりました．実は RapidWeaver は 10 年以上前に Ver. 4 の頃まで使っていたことがあるのですが，随分進化しています．特に別売りのアドオンが非常に充実していて，お金はかかりますが，かなり色々なことが以前よりできるようになっているようです．

ブログについても，今までは Blogger で運用していましたが，今後は RapidWeaver で作成し，大学のウェブサーバーで公開していこうと思います．旧ブログは右のサイドバーのリンクから行けます．]]>
