9 0 0 0 OA 律令国家の北限支配からみた、津軽海峡を挟む古代北方世界の実態的研究
本研究では、律令国家最北の支配拠点である秋田城の性格をまず明らかにし、その秋田城による北方支配や北方世界との交流が、具体的にどのようなもので、どこまで及んだのか、またその一方で北方世界内部のみの、秋田城支配と関わらない交流がどのようなものであったかを検討した。それによれば、秋田城の北方支配は意外に限定的で、北の領域では北の論理に基づく主体的な流通が優勢であったことが明らかになった。一方秋田城の性格については、文献史料の解釈からは非国府説、出土文字資料の解釈からは国府説が有利であることを確認した。最終的結論は今後の課題としてなお検討を続けたい。

The pottery from the Kafukai 1 site on Rebun Island is a grey semi-hard ceramic which was manufactured on turn wheel and fired in a closed kiln at high temperatures. Based on typological analyses, two assumptions have been presented for the origin of the pottery: Sue pottery manufactured in Japan, and ceramic-like pottery made in the far eastern area of the Eurasian continent. In order to confirm these possibilities, the analytical data of the Kafukai-1 pottery were compared to both the Sue and ancient Pohai ceramics. The pottery from Kafukai-1 and the Pohai ceramics had high contents of K and Rb. Although the analytical data were not identical to those of the Pohai ceramics, they were found to be analogous. This, therefore, proves that the pottery could be a Pohai product. At the same time, the possibility of the Kafukai pottery being ancient Japanese Sue-ware was also surveyed. Generally the contents of Ca and Sr in hard ceramics are lower than in Haji ceramics, because in high temperatures above 1000oC, high contents of Ca obstruct the baking of hard ceramics. The date of the Kafukai pottery is inferred to be between the 6th and 7th centuries, and most of the Sue-ware kiln sites in the 6th and 7th centuries were concentrated in the Kinki and Toukai districts. Since the contents of the Kafukai pottery did not correspond to those from the Sue kilnsites, the date of the corresponding kiln was extended to the 9th and 10th centuries. The Mannendani kiln site located in Toyama Prefecture and the Ebisawa kiln site in Akita Prefecture along the Sea of Japan were selected as the corresponding kilns. Discriminatory analyses were carried out between the Mannendani and the Ebisawa kiln sites using the indices of K, Ca, Rb and Sr. Although the Kafukai pottery did not belong to either of these mother groups, the results were analogous to the Mannendani Sue-ware. Whether the pottery is a Mannendani product still remains to be proven. Further analyses of Sue materials produced in the middle and northern areas along the coast of the Sea of Japan indicated that these coastal regions were the most possible areas.

Sphingomyelin (SPM) is a major lipid of bovine milk fat globules and has been attractive in its biological functions. In the epidermis, SPM is a precursor of the biosynthesis of ceramides that play a crucial role in the retention of water and permeability barrier. However, the effect of orally administrated SPM on epidermal function is poorly understood. We investigated the effect of SPM concentrate prepared from bovine milk on the water retaining function in the epidermis by the animal study and the clinical test. Thirteen week-old hairless mice were fed SPM concentrate diets for six weeks. The results showed that 504 mg/day intake of SPM concentrate improved epidermal hydration, transepidermal water loss and ceramides content. We found that 17 mg/day intake of SPM concentrate was enough to prevent water loss and retain water in the epidermis of hairless mice. A placebo-controlled randomized double-blind clinical study of the oral intake was investigated on 25 individuals. The soft capsules containing 330 mg/day of SPM concentrate were administrated to subjects for six weeks. The placebo was prepared with the same amount of phospholipids from soy beans. SPM concentrate group showed significantly higher epidermal hydration than the placebo group. The sebum amount on the skin surface tended to be higher than that of the placebo group. Subjective symptom also revealed that reflectance and elasticity were improved in SPM concentrate group. These results indicate that dietary SPM concentrate improves the water retaining function in the epidermis, and is useful for maintaining the integrity of healthy skin.

荒川(主に仏典担当)・佐藤(主に官文書担当)・小野(主に法律文書担当)は、ロシア科学アカデミー東洋文献研究所所蔵、西夏文字草書体各種資料に関する実見調査と研究を行った。また荒川は敦煌石窟に書かれた草書体西夏文題記なども調査した。各メンバーは各種草書体文献の歴史学的・言語学的研究を発表した。西夏文字草書体字典の雛型を含むいくつかの論文を、研究成果報告書「ロシア所蔵資料の実見調査に基づく西夏文字草書体の体系的研究」にまとめ、これを2016年3月に刊行した。将来的には本研究の成果を活かし、西夏研究に資する字典・資料集の公刊に努めたい。
