The assumption that the 40Ar/36Ar ratio of Ar trapped in volcanic rocks at eruption is atmospheric often gives a large systematic error in the K-Ar dating of Quaternary volcanic rocks younger than 1 Ma. There are two possible sources of error, the existence of excess Ar and mass-fractionated, initial Ar.The major source of excess Ar is supposed to be magma. The 40Ar/36Ar ratio for magmatic Ar in the North-East Japan arc is tentatively estimated to be 340±10 from measurements of Ar in large phenocrysts separated from Quaternary volcanic rocks. Separation of phenocrysts is the most effective to decrease the systematic error caused by excess Ar.The mass-fractionation of initial Ar should give the 38Ar/36Ar ratio which was changed from the atmospheric ratio. This can be checked by determining the 38Ar/36Ar ratio in samples. A peak-height comparison method is preferential to an isotope dilution method in the K-Ar dating of very young volcanic rocks because with the former, both the amount of Ar and the 38Ar/36Ar ratio in a sample can be determined at one measurement, while with the latter, an additional measurement is needed to know the 38Ar/36Ar ratio in the sample. Further, the statistical error in the isotope dilution method overwhelms that of the peakheight comparison method for large atmospheric Ar correction (e.g., 83% correction for 1% relative errors of isotopic ratio measurements). Since the systematic error caused by the mass-fractionated, initial Ar increases greatly with the increasing atmospheric Ar correction, it is important to correct the result for the mass-fractionation. Correction formulae are given.The error sources other than those mentioned above are uncertainty in the blank correction and instabilities in the sensitivity of spectrometer and the Ar isotopic ratio measurement. Especially, Ar in Al- or other metal foil should be taken into consideration for the blank correction. In order to increase accuracy of the K-Ar age obtained, to check the systematic errors by measuring samples together with standard samples is of great importance in the K-Ar dating of very young volcanic rocks.A measurable limit of K-Ar age is affected greatly by the atmospheric Ar correction. For andesites containing 5×10-11 ccSTP 36Ar/g and 2 wt% K, the limit is estimated to be 0.004 Ma for 98% atmospheric Ar correction. For most of Japanese Quaternary lavas which contain 2×10-10 ccSTP 36Ar/g and 2 wt% K, the limit is 0.015 Ma for the same atmospheric Ar correction.

Ibn Taimiya condemns the metaphor theory in some of his works like “al-Haqiqa wa al-majaz” and the Kitab al-iman, and he defends the ahl al-hadith's position that they should refrain from metaphorical interpretation of the Qur'an and the Sunna.First he shows that the metaphor theory which devides the meaning into the literal (haqiqa) and the metaphorical (majaz) is not found in the sayings of the salaf and appears only after the 3rd Islamic century. Then he theoretically refutes the metaphor theory adopted by the theologians, who define the literal meaning as follows: (1) The word has a literal meaning when it is used in the meaning in which it was originally coined; and (2) the literal meaning is what the word means without context.The linguistic notion that a word makes sense without its context originates from the same mentality as that of the philosophical notion that the universal without concrete dimensions has a substantial existence. The latter notion forms a metaphysics Ibn Taimiya severely criticizes.Ibn Taimiya criticizes the metaphor theory on the level of its philosophical foundation, through which he discloses the fictitiousness of the metaphor theory. Thus he gives a theoretical ground to the hermeneutical position of the ahl al-hadith.

The city of Kurume enacted the Basic Ordinance on Kurume's Foods, Agriculture and Farming Villages in March 2004. In line with the basic principle, the Kurume Central Wholesale Market (Kurume Seika K.K.) collaborated with the producers to carry out R&D of a new vegetable, caulibro.Caulibro, a cross between cauliflower and broccoli, is another name for Romanesco (scientific name: Brasica oierancea var. botrytist f. botrytis), a variety of vegetable originally from the Netherlands. The edible portion is a flower bud, and is characterized by a light, sweet taste and short heating time (2 or 3 minutes of boiling).To publicize caulibro to citizens and promote its consumption, the authors developed cooking recipes using this vegetable. The recipes consisted of two staple dishes, five main dishes, six side dishes, and one soup. The cooking method makes use of caulibro's culinary characteristics. The amount per serving was either 70 g for caulibro only, or 140 g in combination with other vegetables. The standard amount used in the Meal Balance Guide for one side dish (sv) was used as a reference.The cooking recipes that were developed have been published on the Kurume Seika's website.

伊豆半島の東半分およびその沖合の相模湾底に100個程度の単成火山の群れである伊豆東部火山群が分布している.大室山(標高580m.写真右上の薄茶色の小山)は,底径1km,比高300mほどの美しいプリン状のスコリア丘で,およそ4,000年前の噴火によってできた.山頂には直径250m,深さ40mのスリバチ状の火口があり,観光リフトによって簡単に登山・散策できる.山頂からの360度のパノラマは見事である. 大室山から流出した溶岩は北方・東方・南方へと流れ下り,地形の凹凸を埋めて伊豆高原(写真中央から右にかけての台地)をつくるとともに,幅4kmほどの範囲で相模湾に流れこんで城ヶ崎海岸(写真左から下にかけての凹凸の激しい海岸)をつくった.海岸ぞいでは,柱状節理・溶岩じわなどのさまざまな溶岩流の造形を観察することができる.写真左上の山は,第四紀火山のひとつである天城山.(写真:白尾元理,2010年1月7日撮影;解説:小山真人)

[Purpose] The purpose of this research was two-fold: (1) to evaluate the effects of father’s parenting participation on parenting stress among mothers with disabled children and (2) more specifically, to investigate the importance of fathers’ parenting participation in decreasing mothers’ parenting stress. [Subjects and Methods] To examine these relationships, this study recruited 82 mothers with disabled children from rehabilitation centers in the Gwangju city. The common characteristics of parents and children, father’s parenting participation, and mother’s parenting stress were assessed using standard questionnaires. [Results] Based on mother reports, findings suggest that as fathers’ parenting participation increases mothers’ parenting stress decreases. [Conclusion] The present study reveals a need for improvement in parenting education and in providing fathers of disabled children with a temporary leave of absence from work. Specifically, this research highlights the importance of shared parenting responsibilities among family members. Finally, our findings suggest that developing a standardized national program for assisting parents with disabled children may help decrease parenting stress in mothers.
