In this paper, the authors report the existence of permafrost at Mt. Taisetsu, Hokkaido, and disdiscuss the climatic significance of permafrost there from a viewpoint of the Quaternary palaecolimatology. Many researchers have observed that patterned grounds, especially sorted circles well developed on many gentle slopes and small depressions at Mt. Taisetsu. And recently it was reported that the networks of fissures of the ground which are similar to large scale ploygons on permafrost in Alaska were found at some places at Mt. Taisetsu. Those sorted circles and nets of fissures suggest the existence of permafrost which is believed to be either relict or recent.By our on-the-spot investigations at Mt. Taisetsu, permafrost was found on one of flat summits (2, 150m) by boring tests and geophysical methods. The maximum depth of the active layer was nearly 2m and the maximum depth of the lower limit of this permafrost was estimated to be 15m or larger. Its frozen soils consisted of weathered fine sands and gravels derived from an andesite bedrock, which are considered as frost-action products. Large sorted circles were form ed on the surface of permafrost.The mean annual temperature and degree-days in this area were calculated as -3.1°C and 2, 400 degree-days by extrapolations on the basis of meteorological data in Asahikawa. The estimated temperature and degree-days suggest that this area has the same climatic conditions as those in central Alasak, where discontinuous permafrost is distributed.Introducing the Popov's theory about the formation of an ice-wedge, we estimated the palaeo-temperature of the surface of the extended permafrost to be -7°--8°C (mean annual temperature) during a past colder period than present. Comparing the estimated chronology of the permafrost with the chronology of permafrost in Alaska and Siberia, and considering the field observations of fossil ice-wedge casts and polygons in Hokkaido, we may conclude that the permafrost at Mt. Taisetsu formed at the last ice age, after then gradually has become smaller, adapting itself to the present climatic conditions.

1990年代から,企業の財務会計,生産管理,販売管理,調達・購買管理,経営管理,人事・労務管理,給与計算,就業管理(勤怠管理)等に関する社内情報システムは,フルスクラッチで開発せず,ERPパッケージを採用して構築することが,盛んに行われている.また,ERPパッケージの導入におけるプロジェクトマネジメントに関する研究も数多く存在する.さて,2010年前後から,筆者が所属する会社では,グループ会社の社内情報システムを統一し,グループ会社の間接業務プロセスの標準化,効率化を推進することを経営施策の一つとして掲げていたが,ある特定のグループ会社群の人事給与・就業管理に関する情報システムの刷新の際,ERPパッケージを用いて構築した.初回のあるグループ会社へのERP導入では,過去の研究論文や文献を参考に,プロジェクト成功のノウハウを取り入れ,納期どおりにカットオーバさせたが,品質が安定せず,運用フェーズに入ってからの仕様変更が相次いだ.そこで,初回の反省を踏まえ,要因解析と対策立案を行った結果,2回目の別のグループ会社へのERP導入では,大幅に品質が向上し,QCD全てが良好な成功プロジェクトとすることができた.本稿では,前記の人事給与・就業管理ERPパッケージの導入における品質改善活動について紹介する.

We found that fatty liver is easily induced in a novel experimental animal, Suncus murinus (suncus) by withholding food. Hepatic triglyceride content increased linearly for up to 24 hours after fasting in these animals, while the glycogen content decreased. Although the glycogen contents returned to the level before fasting at 12 hours after refeeding, the triglyceride contents decreased gradually but did not reach to the level before fasting even at 24 hours after refeeding in suncus. Plasma lipids, glucose and insulin levels decreased by fasting and returned to the levels before fasting between 8 and 24 hours after refeeding. On the other hand, the plasma levels of free fatty acid and ketone bodies were elevated significantly by fasting and decreased rapidly by refeeding. These responses to fasting and refeeding except for the change in hepatic triglyceride are in common with other experimental animals, suggesting that there are no abnormalities not only in glucose metabolism but also in fatty acid metabolism.The study of lipoproteins from this animal revealed that small amounts of lipoproteins with apolipoprotein (apo) E but without apoB were observed in the fraction of density less than 1.08g/ml. In order to learn whether apoB is synthesized by the liver or not, isolated suncus livers were perfused with an addition of [35S] methionine. Small amounts of radioactivity were observed in apoE of VLDL, and fairly large amounts in apoE and A-I in the fraction of LDL+HDL, suggesting that VLDL was secreted with apoE but not with apoB from the liver. Northern blot analysis with use of rat apoB cDNA revealed a weak signal of hybridized rat apoB cDNA between 15Kb and 9Kb in the suncus liver and intestinal mucosa; this is almost the same size as rat apoB mRNA. This finding suggests the presence of apoB mRNA in the suncus.In conclusion, apoB is not secreted from the suncus liver, owing to a defect in intracellular posttranscriptional processing or to ineffective transcription. This might be one of the reasons for fatty deposits in the suncus liver. Suncus may be a candidate for an animal model of abetalipoproteinemia as well as fatty liver due to a defect of apoB synthesis.

公共事業の生産性を向上しつつ品質を確保するためには発注者・設計者・施工者の技術力の結集が不可欠であり,特に発注者のマネジメント力が重要である.本研究では,発注者に必要なマネジメント力を明らかにして不足する場合の技術力補完方策を検討する観点から,全国の地方公共団体を対象にアンケート調査を実施し,得られた719件の回答について整理・分析を行った.その結果,職員の研修等による組織の内側からと民間委託等による組織の外側からの2つの取組みが組織の技術力向上策となる可能性を示唆した.そして,それらの取組みを適切に実施するためには,マネジメント力の評価や資格制度の構築,外部委託時の事業責任の所在を明確化することが重要と考えられていることが明らかになった.
