On the Estimation Method of Cost of Capital Using the CAPM, the Fama-French Three-Factor model, and the Carhart Four-Factor Model.

本稿では、CAPM, Fama-French3 ファクターモデル, Carhart4 ファクターモデルの３つのモデルを用いて、わが国で資本コストを推定する際に発生する問題点について指摘し、その対処方法を提案している。そして、実際のデータを使って、これらのモデルを用いた資本コストの算定方法を具体的に説明している

高齢者パネル調査を用いた社会参画プラットフォームにおける外国語コミュニケーション能力の分析

In this study, an elderly panel survey was conducted to capture trends of active seniors. Main purpose of this paper is to extract relationship between tourism and Gerontology from contents of the survey, which will be contribute to some creations of a social participation platform. Therefore, in analysis of the survey results, factors related to the proficiency level of language communication in foreign languages were examined. As analytical method to grasp trends simple tabulation and cross tabulation of the survey results were confirmed, and important variables were examined by Naïve Bayes. As a main result, as for language communication in foreign languages, it was found that difference between a category that can communicate a little and a category that cannot speak at all was different from the others, and happiness and health level contributed greatly

Electric Field Measurement of a Neon Hollow-Cathode Discharge by the Optogalvanic Spectroscopy with Two-Step Laser Excitation

Optogalvanic spectroscopy with two-step laser excitation was successfully applied to the electric field measurement of a Neon hollow-cathode discharge. Experimental results of the radial distributions of electric field and charge density in the cathode-fall region are presented

Stark Structure of the High Rydberg States of Neon Atom

Stark structure of the high Rydberg states of neon atom is calculated theoretically by the perturbation method. From the viewpoint of electric field measurement in the cathode fall region of glow discharge plasmas, the use of Rydberg states with medium principal quantum number(n～11) is shown to be appropriate

Narrow Bandwidth Double Wavelength Pulsed Dye Laser for Use in Plasma Diagnostics

Nitrogen laser pumped pulsed dye laser system was constructed for use in discharge plasma diagnostics. Double dye laser oscillators with grazing incidence configuration were simultaneously pumped by the single nitrogen laser, thus narrow bandwidth double wavelength laser beams were obtained with a sufficient output power. The dye laser system is applicable to the laser induced fluorescence spectroscopy and the laser optogalvanic spectroscopy
