本研究は、大学卒業後、入社3年目までの若手社員を対象に質問紙調紙を用いてweb調査を実施し、労働価値観が職務満足に及ぼす要因を分析した。顧客満足度調査などで用いられるCS分析を活用した。満足度が高い重点維持項目は、タスクの完結性、達成感（仕事）、社会貢献となり、改善度が高い重点改善項目は、捧げる（組織）、尽くす（組織）、組織貢献となった。今後、若手社員の職務満足を高めていくには、仕事本来の面白さを感じる5つの職務特性要因を仕事に取り入れていく必要がある。また、内発的モチベーションの度合を図るMPS（Motivating Potential Score）を高めていく、職務設計が重要になってくる。経営者や人事担当者は、若手社員の労働価値観を理解して改善していくことが、若手社員の職務満足につながり、離職率の低下となっていく。コロナ禍で労働価値観が変化するなか、若手社員が求める働く魅力づくりをしていくには、インターナル・マーケティングの視点が求められる。, In this study, we conducted a web survey of young employees up to the third year after graduating from university using questionnaire survey, and analyzed the factors that labor values affect job satisfaction. We used CS analysis used in customer satisfaction surveys. The priority maintenance items with high satisfaction were task identity, social contribution, and sense of accomplishment (work), and the top priority improvement items with high improvement were dedication (organization), devoted (organization), and organizational contribution. In the future, it is necessary to incorporate five job characteristic factors that make the work originally interesting. In addition, job design that raises MPS (Motivating Potential Score) to increase the degree of intrinsic motivation becomes important. For managers and human resources personnel, understanding and improving the labor values of young employees will lead to job satisfaction of young employees, and the turnover rate will decrease. As laborer values change due to corona disaster, an internal marketing erspective is required to create the attractive work that young employees demand.

本研究では、国立大学の大学生を対象に質問紙調査データを用い、大学生がインターンシップの経験から感じた職務満足の要因を分析した。分析は、顧客満足度調査などで用いられるCS分析を活用し、各要因を数値化して、満足度の判断を分かりやすくするために偏差値で表し、CSグラフで可視化をした。結果、最も満足度の高い重点維持項目の要因は「人としての成長」となり、 最も改善度が高い最優先改善項目の要因は「フィードバック」となった。また、成長を感じるには、5つの職務特性と内発的モチベーションの度合いを図るMPS（Motivating Potential Score）が関係している。 今後、企業が職務満足度の高いインターンシップを実施していくには、MPSを上げながら成長のできるプログラムを軸に考え、最も改善度の高いフィードバックを見直すことで職務満足度の向上につながると推測される。企業にとって大学生を採用につなげていくインターンシップは、今後の採用戦略として重要な位置づけとなってくる。

In recent years, competition in the market is becoming more intense. The life span of the product is becoming shorter and shorter, so manufacturing companies are needed to develop new product, ship it to the market and sell it quickly. Not only products of mass production but also products of make-to-order production are wanted to do same things. So make-to-order products are needed to produce and ship for prospects without orders. Even make-to-order products are used common items in many parts, so they usually have basic design part and fluctuating parts that are decided by customer. However most ofcompanies that make make-to-order products don’t approach standardization of parts, so they can’t plan production schedule before they receive orders. This paper proposes a product planning method for make-to-order production in advance. Therefore this paper separate basic design parts and fluctuatingparts to control them by part number and show production planning model. This paper also proposes effectiveness of the method thorough a simulation experiments.

The software which converted from three dimensional model of woven fabric structures to STL file was developed. STL file is a general-purpose three-dimensional CAD data format and loaded by CAE (Computer Aided Engineering) system. The three dimensional modeler of woven fabric structures was applied as preprocessor of CAE for analysis of woven fabric properties. The analysis by FEM (Finite Eement Method) and MPS (Moving Particle Simulation) using three dimensional model of woven fabric structures was enabled by applying this software. This analysis allows the various physical properties designs of woven fabric.

This paper surveys the arguments concerning China’s GDP statistics. Topics covered include the upward adjustments of 30％ or more for China’s official GDP by the World Bank in its publications 1994 to 1998, and the upward adjustment of about 10％ by Maddison in his “Chinese Economic Performance in the Long Run” published by the Development Center of OECD in 1998. The paper also covers Rawski’s criticism of China’s GDP growth rate for example in “What is happening to China’s GDP statistics?”, a criticism which is based on inconsistencies between government statistics. The paper also looks at various commentaries on China GDP statistics made widely by scholars and the media in the United States, Europe, Japan and China since 2000. In addition, the rebuttal of some of the criticism and adjustments, and the three retroactive revisions of the GDP that have been made so far by the National Bureau of Statistics of China (NBS) are discussed. The survey shows the possibility that China’s GDP statistics have been underestimated conservatively and have very likely not been overestimated as the media suggest. This paper also considers the consistency between the Gross Regional Product (GRP) estimated by local governments and the GDP estimated by the central governments in Japan and China, and the problems of GDP estimates based on the concept of MPS., 1. はじめに2. 1994-98年における世銀による中国公式GDPの上方調整3. 1998年のMaddison, A. による中国GDPの調整4. 2000年以後の中国GDP統計をめぐる論争 1) 地域GRPと国GDPとの整合性について 2) MPS概念に基づく推計の問題5. 遡及改訂からみるこれまでの論争6. おわりに

本稿では, 20 世紀の90 年代における中国のサービス業の成長をめぐる基本状況を明らかにし,さらに, サービス業の成長が一国経済全体の成長より遅れた, 体制面, 統計面の要因などを検討した。In the 1990’s, the Chinese GDP growth rate was 9.7％ on average, but although the prices of services rose faster than those of goods, the growth rate of the service sector was only 8.5％, which was lower than the GDP. The present paper describes the basic situation of the Chinese service sector in the 1990’s, and examines factors causing the service sector’s lower growth from institution and statistical viewpoints.

新しい推進システムとして注目を集めている磁気プラズマセイルは、高い推力電力比と比推力が達成できると期待されており、外惑星探査におけるコスト削減や飛行時間の大幅短縮に貢献できる可能性を持っている。我々は、この磁気プラズマセイルについて、3次元のハイブリッドコードを用いて、有限ラーマ半径効果を考慮した数値解析を実施した。解析は磁場の展開と太陽風-磁場の相互作用の2つのメカニズムに関して実施し、磁場展開については粒子的効果が支配的となる領域においても数値解析を実施し、太陽風-磁場の相互作用については磁気圏代表長で規格化される抗力係数を用いて推力特性を評価した。本論文では、それに加え、磁場の展開における計算コストに関する問題点と磁場の展開と太陽風-磁場の相互作用を同時に解析する必要性について述べた。, Recently, a new propulsion system called Magneto Plasma Sail (MPS) attracts attention, and it is expected to have high thrust to power ratio and high specific impulse. The MPS produces the propulsive force by the interaction between the solar wind and the artificial magnetic field inflated by the plasma injection. By using a 3D hybrid simulation code, we investigated, considering the finite Larmor radius effect, the inflation by the plasma injection and the interaction between the solar wind and the artificial magnetic field, respectively. In this paper, we showed the results of the magnetic field inflation with the finite Larmor radius effect and investigated the dependence of thrust on the size of the magnetic cavity. Also, we discussed the problem about costs of large scale calculation related with above numerical analysis and the necessity of concurrent analysis including both the inflation and the interaction between the solar wind and the magnetic field., 資料番号: AA0049193003, レポート番号: JAXA-RR-05-014

近年、住宅において気密性や断熱性が重視されるようになったことから、湿気の停滞などにより室内において微生物が発生しやすい環境を生んでいる。Acanthamoebaは汚染された水や手でコンタクトレンズを装着することで角膜に感染し、角膜炎を引き起こす。また、Rhodotorulaは浴室に広く存在し、材質を傷めるだけでなく、感染症の原因菌となる。そこで、室内の水回り環境で問題となるアメーバや酵母に対する微生物防除と防菌剤としての応用を検討した。
