In order to solve a mechanical inconsistency that the Osaka Bay basin exists between the Median Tectonic Line (MTL) and Arima-Takatsuki Tectonic Line (ATTL) (right-lateral left-stepping faults), we attempted to investigate and evaluate the basin forming mechanism at the termination of right-lateral left-stepping faults by means of the dislocation modeling.<BR>The results of the numerical simulations show that the sedimentary basin can be formed at the termination of the right-lateral left-stepping faults develop, if the secondary fault caused by the rightlateral motion is a reverse fault and its displacement is larger than 20% of the lateral motion. We applied this model to the fault distribution in the Kinki district, and found that tectonic structures around the Osaka Bay can be explained by combination of 1) the right-lateral motion of the MTL and ATTL and 2) the reverse motion of their secondary faults, <I>i.e</I>., Nara-Toh'en Fault, Ikoma Fault and Rokko-Awaji Fault Systems.

In the classical Islamic jurisprudence the <i>Jihad</i> is defined as 'to expend one's life, wealth, and words in the war or the defence against infidels'. But after the collapse of the Ottoman Caliphate, the political situations of the Islamic world drastically changed, which called various responses among Muslim intellectuals. Faraj, the ideologue of the Egyptian '<i>Jihad</i>' group demonstrates that contemporary rulers apostatize from Islam because they do not rule according to the <i>shari'a</i>. So it turns to be individual obligation for Muslims to go <i>jihad</i> against the apostate rulers, for the <i>jihad</i> against apostates is to precede that against native infidels and the near enemy is more dangerous than the distant. But the <i>jihad</i> against the rulers has now no hope to succeed, so Shaikh 'Abdulgadir, a member of the '<i>Jihad</i>', argues that the military training for the <i>jihad</i> is incumbent on every sane adult Muslim who has the necessary equipments and that Muslims should elect a qualified commander by lack of the caliph.<br>Dr. 'Umar 'Abdurrahman, the mentor of the '<i>Jama'a Isldmiya</i>', who classifies the rulers of the Muslim states into six categories, distinguishes the contemporary ruler from the traditional types of rulers and coins the word <i>mustabdil</i> for that. He concludes that the <i>mustabdil</i> is infidel and consequently has no legitimacy to rule and that Muslims must rise against him. Abu Ithar, Dr. 'Umar's disciple refines the conception of <i>mustabdil</i> and proves that the war against a <i>mustabdil</i> is not the rebellion which is one of the <i>hudud</i> crimes, but Muslim's duty.<br>Thus the fight against evil rulers is justified both in the framework of the <i>jihad</i> theory by Faraj and 'Abdulgadir, and in the discussion about the legitimacy of the caliph by Dr.' Umar and Abu Ithar.<br>The 'revolutionary <i>jihad</i> theories' radically differ from the classical theory of the <i>jihad</i> and the caliphate. In the classical Islamic jurisprudence the <i>jihad</i> is defined as the war against infidels and strictly separated from the notion of apostasy which is one of the <i>hudud</i> crimes. The caliphate theory is inserted in the chapter of the rebellion in the Islamic jurisprudence, so that it serves mainly for the justification of the temporal ruler and excludes the possibility of discussing the caliph's apostasy.

本稿では,沖縄県竹富島において島を代表する存在である「赤瓦の町並み」が,どのように保存され今のような姿に至ったか,また,「赤瓦の町並み」が町並み保存運動の中で,伝統的建造物群保存地区という文化財としてどのように再生されていったか,伝統文化の創造という観点から考察する.町並み保存のプロセスを検討していくことによって,「伝統的」であると見なされている町並みが本来はいかなるものであるのか,さらに,「伝統的」であるとはいかなることなのかが,明らかになるのである.<br> 本研究の視点は,文化と真正性,伝統文化の創造,観光と伝統をめぐる諸研究と共通するものであり,本研究で取り上げた文化財として位置づけられている伝統的町並みは,研究者・行政・住民の三者の思惑が絡み合ったところに生じたもので,近年注目されっっある「ふるさと」の文化,地域の伝統文化を考える上で,格好の素材でもある.

The population density of western lowland gorillas in the Nouabalé-Ndoki National Park, northern Congo, was estimated both by the "bed-census" method and the "counting" method based on bed-count and direct observation. The density was calculated as 1.92-2.56animals/km<sup>2</sup> and 2.29-2.61 animals/km<sup>2</sup> respectively. Because this was the first time to attempt the "bed-census" method in the Ndoki forest, direct comparison of population density was possible between western lowland gorilla populations at all study sites. It was concluded that the density of the Ndoki gorillas was highest. High population density of the Ndoki gorillas was considered to be possible because they have access to a wide repertoire of foods such as highly nutritious terrestrial herbaceous vegetation (THV) and various kinds of fruits and seeds, corresponding to the seasonal fluctuation of food availability. Although the feeding habits and habitat were different between western and eastern gorillas, they shared a basically one-male group composition, large group size, and unit groups that largely shared their home ranges with each other.
