新聞記事や質問紙調査における自由回答など、社会調査において計量的な分析の対象となるテキスト型データには、様々なものが挙げられる。これらのテキスト型データを計量的に分析する際、従来はCorrelationalアプローチかDictionary-basedアプローチのうち、いずれかが用いられることが多かった。前者は多変量解析の応用、例えば、クラスター分析を用いて頻繁に同じ文書の中にあらわれる言葉のグループを見つけだすといった方法で、データ中の主題を探索するアプローチである。それに対して後者のアプローチでは、分析者の指定した基準にそって言葉や文書が分類され、計量的な分析が行われる。本稿ではこれらのアプローチを検討し、それぞれに一長一短を持つこれら2つを、互いに補い合う形で統合したアプローチを提案する。そして、その実現に必要なシステムを作製・公開するとともに、本アプローチ・システムを用いて自由回答データの分析を行った例を示す。その上で、従来のアプローチに対する本アプローチの有効性について若干の検討を加える。

Petersite–(La) is a new mineral of the petersite series in the mixite group with an ideal formula of Cu6La(PO4)3(OH)6·3H2O from Ohgurusu, Kiwa–cho, Kumano City, Mie Prefecture, Japan. The mixite–group minerals occur in small cavities coated by chrysocolla developed along quartz veins. Four members from different cavities have been identified: petersite–(La), petersite–(Ce), petersite–(Y), and agardite–(La). Petersite–(La) occurs as a radial aggregate formed by acicular to hexagonal columnar crystals of yellowish green color. Crystals are elongated along [001] and the prismatic face is probably formed by {001} and {100} or {110}. It is non–fluorescent in UV light. Crystals are brittle, cleavage and parting are non–observed, and fracture is uneven. These characteristics are common in other mixite–group minerals. The calculated density of petersite–(La) is 3.33 g/cm3, based on the empirical formula and powder XRD data. It is optically uniaxial positive with ω = 1.680(3) and ε = 1.767(3) (white light), and pleochroism varies from light green to yellowish green. Based on the WDS analysis, the empirical formula of petersite–(La) calculated on the basis of P + As + Si = 3 is (Cu5.692Fe0.010)Σ5.702[(La0.148Ce0.122Nd0.117Y0.086Sm0.022)Σ0.495Ca0.372]Σ0.866(P1.890As0.799Si0.311)Σ3O10.320(OH)7.680·3H2O. Petersite–(La) is hexagonal (P63/m) with a = 13.367(2) Å, c = 5.872(2) Å, and V = 908.7(4) Å3 (Z = 2). The eight strongest lines of petersite–(La) in the powder XRD pattern [d in Å(I/I0)(hkl )] are 11.578(100)(100), 4.377(28)(210 + 120), 3.509(18)(211 + 121), 3.211(10)(310 + 130), 2.898(14)(221, 400), 2.656(10)(320 + 230), 2.526(11)(410 + 140), and 2.438(25)(212 + 122). Petersite–(La) is the third defined member in the petersite series and corresponds to the La–dominant analogue of petersite–(Y) and petersite–(Ce).

The authors investigated five injury incidents and one death incident of humans due to attacks by brown bears (Ursus arctos)during hibernation , occurring in Hokkaido Japan during the 26 years from 1970 through to 1995. Details and characteristics of these bear attack incidents and countermeasures to prevent attacks and injury are described within. The reason bears attack while they are hibernating is to protect their den from possible human intrusion. If they scene a possible threat close to their den they will leave their den to drive off the perceived threat. A hibernation den is a tunnal cave dug by bears in a mountain slope. Bears in Hokkaido usually start hibernating from late November to late December and finish hibernating from late March to early May. It has been observed that in general dens with a larger than average entrance have been a feature in relation to attacks on humans. In the one reported case of a human death due to a bear attack in Hokkaido, occurred in early December very early in the bears hibernation. The bear stood up and attacked with its hand claws. All other reported attacks did not lead to death. These attacks all occurred after late February. This is past the half way point of the bears hibernation. The bears had used up so much energy in keeping warm during winter the bears therefore did not have enough energy to stand up and attack. They attacked their human victims only with their teeth. Therefore it appears in order to minimize injury from bear attacks. It is better to start work in bears hibernating areas after late February, which is past the half way term point of hibernation. Bears usually don't have enough energy to stand up and attack past the half way point of their hibernation. Standard safety measures to help prevent bear attacks on humans, people shoud carry a sound-making instrument, such as a whistle or a bell, and a hatchet(a big knife) for self-protection when entering an area presumed to be a bears habitat. While walking, people should blow or rattle the sound-making instrument, or raise their voices in order to avoid encountering bears unexpectedly. Because bears dislike hibernating in a place where the environment has been artificially changed, minor modifications to the environment are effective in preventing bears from making dens. Bears lurking obstinately in their den should not be killed. People can safely work around a bear's den if they remain 50 to 100 m away from it. Bears often use several different dens. Therefore, bears escaping from a den due to the intrusion of humans usually enter another den, and it is not necessary to chase and kill them. When encountering a bear people should never run to escape or feign death as the bear is sure to attack. The best actions are to stand, be confident and shout at the bear in a loud voice. Such actions are often successful and the bear will leave. If a bear should actually attack the best response is to deliver a blow of a hatchet on any part of the bears body. This will increase the chance of survival.

On May 10, a 47 year old fisherman was killed and eaten by a sole, 2 year 3 month old male bear (Ursus arctos). On the following day in the same area, two women (30 and 50 years old) were out collecting edible wild plants when they were attacked and wounded by the same bear that killed the fisherman. The bear had clearly eaten the fisherman's facial, head and throat muscles, right arm, right pectoral muscles and ribs. The facts that the bear had attacked, dragged the man to a comfortable place and then ate, suggests that the bear's attacking purpose was for food. The two women had come within a few meters of the bear and were attacked by the bear when trying to flee. Both women were injured in the head region. The first woman attacked was the 50 year old woman. She fought off the attack by repeatedly beating the bear with a stick. The bear then attacked the younger woman but was astonishingly driven off when the elder woman produced a large sound with her car horn. The bear had evidently attacked the women with the purpose of repelling them from his nearby food source ; the fisherman's corpse. In the past 30 years, the incidence of bear attacks on people, other than hunters, has been limited to either sole young bears or dam with offspring. The young bears were mostly two or three years old, however in some rare cases, the bear has been four years old. The causes of these attacks may be divided into three categories, i.e. to eat, to repel or to play. The incidents mentioned above fit within these categories. In the case of the fisherman, it may have been possible for him to have safely escaped if he had repelled the attack with a hatchet that may be carried legally.

The anodic passivation film formed on iron in neutral borate-buffer solution has been studied by using ellipsometric, electrochemical, and gravimetrical techniques. The film can be dissolved from its outer surface by applying a cathodic current in borate-buffer solution at pH 6.35 in which the reductive dissolution,<BR>(This article is not displayable. Please see full text pdf.) <BR>\oindentproceeds at 100 per cent current efficiency. Ellipsometric measurements carried out during the galvanostatic-cathodic reduction of the film in this solution reveals that the film consists of two layers, an inner layer with the optical constant 3.0&minus;0.5<I>i</I> and an outer layer with the constant 1.8&minus;0.1<I>i</I>. It is also shown that the density of the inner layer is in agreement with that of &gamma;-Fe<SUB>2</SUB>O<SUB>3</SUB>.<BR>The inner layer thickness increases linearly with the passivating potential, and the potential extrapolated at zero thickness of the inner layer corresponds to the equilibrium potential of the anodic formation of &gamma;-Fe<SUB>2</SUB>O<SUB>3</SUB>,<BR>(This article is not displayable.

Ellipsometry is widely used as a powerful tool in the research of nano-science and the thin film engineering. The thickness of the film of sub-nm order can be measured by ellipsometry with high accuracy along with its refractive index. Ellipsometry is a non-destructive method and is ambient free in the measurement. Nowadays, its applications range over a variety of field. This article describes an introduction to ellipsometry with some its applications. And the perspective of ellipsometry is also briefly summarized.
