<p>本研究の目的は，人形用キモノの形態学的特徴から衣服のデザイン要素としての「キモノらしさ」を明らかにすることである。人形用のキモノは，和裁の理論にとらわれない方法で，人のキモノをより特徴が際立つように簡略化し，再構成したものであると考えられる。人形用キモノの特徴を調査するため，1/6 スケールの着せ替え人形「ジェニー」用に作られた 17 点のキモノ作品例を収集し，分類した。実際にそれらの人形用キモノを再現し，制作過程の検証と形の観察を行った。各作品の特徴を人のキモノと比較し，材料と各パーツの構成の関係，制作の難易度，各部の幅の比率，人形の身体の形との関係に着目した。考察の結果，キモノらしさのデザイン要素は，人形用キモノ全体に共通する特徴としての一定の形の要素に加え，布幅に由来する各部の幅の比率，材料を無駄なく生かす使い方にあると結論づけた。また人形のキモノがこれらの要素を踏まえつつ，自由な解釈により制作された様子を示した。</p>

The demand of wood is increasing, but the supply is limited, on the contrary, there are amount of potential young teaks (Tectona grandis L.f.) from thinning of teak plantations that could contribute to meet this demand. During the time from planting until harvesting (rotation age), a number of young teak trees, which comprise mostly sapwood, are felled regularly due to the thinning to stimulate the better growth of the remaining teak trees in the plantations. There are at least 1.2 million hectares of teak plantations in Java, Indonesia, and 3.146 million hectares in other countries. In one of the teak plantations, for 1 hectare with the average site quality and the rotation age of 40 years, from 1,769 5-year-old teak trees will be felled regularly during the rotation age until 277 39-year-old teak trees remain at harvesting. From this study, consider the significant amount of young teaks from the thinning is available, it is necessary to utilize these potential material become suitable products by taking the advantage of its properties and prominent characteristics, e.g. border patterns and lighter color of the sapwood, to enhance its utilization and value.

Potential young teaks (Tectona grandis L.f.) from the thinning of teak plantations can be utilized for making products by taking the advantage of its mechanical properties and characteristics. This research assess the mechanical properties and the characteristics of sapwood and its heartwood of young teaks from each of age classes in the rotation age of 40 years of teaks plantation in West Java area, Indonesia. Mechanical properties of young teak are the determination of its MOR and MOE, and it has been determined that the difference strength between sapwood and its heartwood among the age classes is not significant. Characteristics of young teak are intended to the variation of its grain pattern and the color intensity. The lighter color of sapwood of young teak has the specific effect that the color of colorant will appear more attractive than on its heartwood, and the combination of the contrast border pattern between sapwood and its heartwood part will create the unique appearances.

Aiming to approach Product Subjective Sustainability experientially and initiating to expand this concept analytically, this paper presents the process and results of an analytical study on the evolution of users' Kansei toward their mobile phone during its entire lifecycle in two different contexts, Japan and Iran. As the major outcomes of this study, the patterns of evolution of two groups of Japanese and Iranian subjects' Kansei over the lifetime of their mobile phones are extracted and accordingly the trends of subjective sustainability of mobile phones are drawn and compared between these two contexts. As the findings of this study show, attachment is the most important trend in such a subjective sustainability and may appear at the different levels. However, it is not the only trend in this regard. Furthermore, a lack of such a subjective sustainability, which has several causal trends, is seemingly an ongoing problem in Iran.
