<P><B>Under the Dome</B></P><P>The superconducting transition temperature <I>T<SUB>c</SUB></I> of copper oxides has a dome-shaped dependence on chemical doping. Whether there is a quantum critical point (QCP) beneath the dome, and whether it is related to the enigmatic pseudogap, has been heavily debated.

Prospects of Activated Sludge Process in Japan - Its Past, Present, and Future -

Fujita, Masanori Korean Wetlands Society 2007 한국습지학회지 Vol.9 No.1

Our life totally depends on activated sludgeprocess for treatment of wastewater: sewage and industrial wastewater. Activated sludge process was the epoch-making technology in Environmental field. One century has been almost passed since the process was developed in England, and the process is still on the development of improvement. Here, history of activated sludge process, its mechanismsof treating the wastewater, expectations that we had on the process in the past, and future image and possibility on the process were presented. By reviewing the events related to the process, we can foresee potentials for new possibility of activated sludge process.

일본에서의 『사기(史記)』 년대학(年代學) 연구

( Fujita Katsuhisa ) 성균관대학교 대동문화연구원 2014 大東文化硏究 Vol.88 No.-

司馬遷이 저술했던 『史記』가 일본에서 어떻게 읽혀져 왔는가에 대해서는 몇 가지 역사적 단계가 있다. 우선 일본에는 奈良 시대 이후에 『사기』의 紙寫本이 전래되어 古抄本이 남아 있다. 송대 이후의 판본으로는 室町 시대에 전래된 『사기』 南化本이 있다. 또 江戶 시대에는 외국에서 들어온 漢籍에 대해서 江戶, 京都, 大阪 등지에서 和刻本이 간행되었다. 본고에서는 이러한 일본의 『사기』 수용 가운데, 특히 『사기』 十表의 年代學이 어떻게 전개되었는지, 그 특징을 고찰하고 근년의 중국 簡牘을 통한 연구를 소개하고자 한다. 그 요점을 정리하면 다음과 같다. 우선『사기』 紙寫本은 本紀나 列傳을 중심으로 하고, 十表 부문은 전해지지 않았다. 또 『사기』 南化本에서는 본기나 열전에 비해 十表, 八書에는 欄外에 기재된 주석이 매우 적다. 그리고 에도시대의 대표적인 주석인 中井履軒의『史記雕題』에서도 十表, 八書에는 欄外에 기재된 주석이 적다. 이러한 경향은 일본의 『사기』 수용이 본기나 세가, 열전의 역사나 이야기를 중심으로 하여, 十表의 年代學에 대해서는 관심이 적었음을 보여주고 있다. 그러나 근래에 들어 紀年 資料의 모순점에 대해 고찰한 연구나 『사기』 十表의 편집 의도를 고찰한 연구가 있었고, 또한 睡虎地秦簡 『編年記』나 淸華簡 「楚居」·「繫年」을 통해 『사기』의 연대학을 알 수 있다. There are several stages through Japan``s history as to how the 『Sagi』 of Samachen(司馬遷) had been read in Japan. The paper manuscript(紙寫本) of 『Sagi』 was introduced for the first time to Japan after Nara(奈良) period, now existing as Gochobon(古抄本). The copy made after Chinese Song period is 『Sagi』Namhwabon(南化本) that was handed down in Muromachi(室町) period. During Edo(江戶) period, Hwagakbons(和刻本) were published for the imported Chinese books in Edo(江戶), Gyoto(京都), Osaka(大阪) and other regions. This study aimed to examine how 『Sagi』 had been accepted to Japan, especially how the chronology of 『Sagi』 「Sippyo(十表)」 was developed, and to introduce the recent studies on Chinese Gandok(簡牘). Points are as follows; At first, the 『Sagi』 paper manuscript is centered on 「Bongi(本紀)」 or 「Yeoljeon(列傳)」 and does not include 「Sippyo(十表)」 part. 『Sagi』 Namhwabon has very little marginal notes in 「Sippyo」 and 「Palseo(八書)」 compared with 「Bongi」 or 「Yeoljeon」. Also there are not many notes in the 「Sippyo」 and 「Palseo(八書)」 of 『Sagijoje(史記雕題)』 a representative notes written by Nakai Riken(中井履軒) during Edo period. Such trends show that Japan``s 『Sagi』 acception was centered on the history and stories of 「Bongi」, 「Sega」 or 「Yeoljeon, not paying much attention to the chronology of 「Sippyo」. However, recently, there has been studies on the contrarieties of chronological orders discovered in materials and on the editorial intentions of 『Sagi』 and 「Sippyo」. Also, 『Pyeonnyeongi(編年記)』 or 「Chogeo(楚居)」 an 「Gyenyeon(繫年)」 handled Sagi chronology.

Some Considerations for the Modernization of the Rome Convention, in case of Unlawful Interference

Fujita, Katsutoshi Korea Society of Air Space Law and Policy 2008 한국항공우주정책·법학회지 Vol.23 No.1

Most compensation issues are regulated under domestic law where third parties are suffered damage from crushes of aircrafts or their falling objects. This issue was internationally recognized. A Convention to unify the rules of the law concerning damage caused by aircraft to the third parties on the surface was signed in May, 1933( the 1933 Rome Convention) and it became effective in 1942. Later, modernization was carried out through the 1952 Rome Convention and the 1978 Montreal Protocol amending the 1933 Rome Convention. Ratifying States either to the Convention or to the Protocol is not as many as those States to the Warsaw Convention concerning air-transport. In 1999, which was a turning point of changes of centuries from the twentieth century to the twenty first century, the Montreal Convention was passed to modernize the Warsaw Convention, and was quickly widespread. On September 11 2001, the coordinated simultaneous terror attacks occurred. In the circumstances, the issue modernizing the Rome Convention came up. Thus, workout under the initiatives of the Legal Committee of the ICAO is under operation to adopt new Rome Convention. In Japan, a study on the ICAO Draft Convention was operated by which a working study group composed of experts from academy, industry and government was set up. This article, being based on that study, clarifies issues and gives future perspectives. This article presents author's individual views.

Mechanical Properties and Microstructure of Aluminum Alloys with Dispersed Nanoscale Quasicrystalline Particles

Fujita Masashi,Kimura Hisamichi,Inoue Akihisa 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1

New Al-based alloys with very high ultimate tensile strength were developed in high Al concentration range of 91-95 at.% for Al-Fe-Cr-Ti-M (M: Co and Mo) systems and Al-Fe-Cr-Mo-Ti-Co system by the dispersion of nanoscale quasicrystalline particles in Al phase. The effect of adding elements, M was discussed in the viewpoint of stability of super-cooled liquid state and formation ability of quasicrystalline phase. The P/M Al-Fe-Cr-Ti-M alloys with dispersed nanoscale quasicrystalline particles exhibited ultimate tensile strength of 350MPa at 573K and 200MPa at 673K.

Effects of Non-protein Energy Intake on the Concentrations of Plasma Metabolites and Insulin, and Tissue Responsiveness and Sensitivity to Insulin in Goats

Fujita, Tadahisa,Kajita, Masahiro,Sano, Hiroaki,Shiga, Akio Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.7

A glucose clamp technique was used to investigate the effects of non-protein energy intake on tissue responsiveness and sensitivity to insulin for glucose metabolism in intact adults male goats. Three goats were fed diets at 1.0, 1.5 and 2.0 times of ME for maintenance, each for 21 d. Crude protein intake was 1.5 times of maintenance requirement in each treatment. Tissue responsiveness and sensitivity to insulin were evaluated using a hyperinsulinemic euglycemic clamp technique with four levels of insulin infusion, beginning at 13 h after feeding. Concentrations of plasma metabolites and insulin were also measured at 3, 6 and 13 h after feeding, for evaluating effects of non-protein energy intake on the metabolic status of the animals. Increasing non-protein energy intake prevented an increase in plasma NEFA concentration at 13 h after feeding (p = 0.03). Plasma urea-nitrogen and total amino-nitrogen concentrations decreased (p<0.01) and increased (p = 0.03), respectively, with increasing non-protein energy intake across time relating to feeding. Plasma insulin concentration was unaffected (p = 0.43) by non-protein energy intake regardless of time relating to feeding. In the glucose clamp experiment, increasing non-protein energy intake decreased numerically (p = 0.12) the plasma insulin concentration at half-maximal glucose infusion rate (insulin sensitivity), but did not affect (p = 0.60) maximal glucose infusion rate (tissue responsiveness to insulin). The present results suggest that an increase in non-protein energy intake may enhance insulin sensitivity for glucose metabolism, unlike responsiveness to insulin, in adult male goats. The possible enhancement in insulin sensitivity may play a role in establishing anabolic status in the body, when excess energy is supplied to the body.
