This study aimed to examine the theoretical consideration and concept of hybrid that could be applicable to wood product design, to analyze design trend according to the morphological transformation by means of combination of hybrid material and function, to understand the correlation between type of wood product and materials and to apply it to the domestic and overseas hybrid concept of wood product design study. A study of assembling output by empirical experiment to embed natural resources into acrylic resin in order to develop wood products was carried out. And an wood product was suggested that satisfied lighting and hanger function through a new wood product design development combined with hanger function and lighting function. Through such process, a new design paradigm was suggested to cope with the periodic trend and to induce mass production of designed product. Thus, this study set a new guideline for activating wood product design and attempted to meet the social demand of encouraging new value creation.

Civil infrastructures are always subjected to various types of hazard and deterioration. These conditions require systematic efforts to assess the exposure and vulnerability of infrastructure, as well as producing strategic countermeasures to reduce the risks. This paper describes the needs for and concept of advanced sensor technologies for risk assessment of civil infrastructure in Japan. Backgrounds of the infrastructure problems such as natural disasters, difficult environment, limited resource for maintenance, and increasing requirement for safety are discussed. The paper presents a concept of risk assessment, which is defined as a combination of hazard and structural vulnerability assessment. An overview of current practices and research activities toward implementing the concept is presented. This includes implementation of structural health monitoring (SHM) systems for environment and natural disaster prevention, improvement of stock management, and prevention of structural failure.

Fatigue evaluations for the rotor blades of commercial or military rotorcraft have been carried out using the safe life concept since 1950s. Particularly, in the case of a rotor blade made of a composite material, a highly reliable fatigue life could be predicted by evaluation the cumulative damage using combination of fatigue life curve and load spectrum. However, there is a limit in adequately evaluating the strength reducing phenomena caused by damages or defects generated during the manufacturing process or impact damage induced by operational usages, using only the safe life concept. In this study, the fatigue evaluation process based on the damage tolerance concept is described and illustrated by means of successful application to substantiate the retirement time of composite rotor blades.

This paper summarized concept, manufacture and results of the micro-tubular solid oxide fuel cells (SOFCs). The cells were fabricated by co-sintering of extruded micro-tubular anode support and electrolyte coating layer, and then additional cathode coating. The cells showed quick voltage rising within 1 minute, and the electrochemical performances were closely related to the balance of fuel utilization and performance loss. And a thermal-fluid simulation model was also reported in combination with the electrochemical evaluation results on the GDC-based micro-tubular SOFCs.

Advancements in digital technology have led to increased usage of digital devices among teenagers. The coronavirus disease 2019 pandemic and the subsequent implementation of social distancing policies have further accelerated this change. Consequently, a new concept called the metaverse has emerged. The metaverse is a combination of a virtual reality universe that allows individuals to meet, socialize, work, play, entertain, and create. This review provides an overview of the concept and main features of the metaverse and examples of its utilization in the real world. It also explains the unique developmental characteristics of childhood and adolescence, as well as the possible negative influences of the metaverse on them, including addiction, antisocial behavior, cyberbullying, and identity confusion. This review summarizes several suggestions for future research because the metaverse is a relatively new concept.

We find ourselves living in a post-human era when technology and images coexist with humans. A cyborg, a combination of an organic body and a machine could be called a human fused with a machine. It could be understood as a new species where humans and machines have combined rather than simple protoplasm or an organic body. The purpose of this study is to demonstrate that a concept of a body in post humanism era is finding expression in fashion illustration through cyborg images. The concepts of post humanism and cyborg are analysed by means of research into literature and characteristics in which cyborg images as post humans are expressed through art, and images of a cyborg body in fashion illustration and their meanings are explored with the foregoing as a framework of reference. Cyborg image reflects new images and concept of a human in post humanism. The cyborg body images in fashion illustration are expressed through the addition of mechanical images, digital virtual body, monster image by means of hybrid combination, distorted physical transformation and fragmented body and body absence. And cyborg image in fashion illustration shows the extension of body concepts through the technology and uncertain and ambiguous identity.

Terms are linguistic realization of technical concepts. Term constituents are important elements used for representing the concept. Since many new terms are created from the modification or combination of existing constituents, it is important to analyze term constituents for understanding the concept of the term. It means that term constituents offer clues for understanding the concept of terms. However, there are a couple of difficulties in matching concept unit and term constituents such as mismatching between a term constituent and a concept unit, homonym of term constituents and synonym of term constituents. To solve them, it is necessary to recognize concept units of term constituents. In this paper, we define an English term constituent as the concept unit and use an alignment algorithm between English-Korean term constituents in order to recognize concept units of term constituents. By our alignment algorithm we recognize Korean term constituents corresponding to an English term constituent with about $93\%$ precision.

Objective : analysis of words related with medical concept and context of paragraphs in Suwen of Huang Di Nei Jing based on concreteness and ideality. Method : First, I extract words having medical concept out of the whole sentence of Huang Di Nei Jing. and classifies them according to the type of medical concept. Second, I classify all sentence of it on the basis of analysing of the words. Result : 1. There are not an interrelationship between the abstract and concrete words from the perspective of cause and effect. Abstract words group are divided into two different parts according to the fundamental character. There are the concept being formed from pure idea and the concept being formed from material idea. The main words composed most important part of the oriental medicine have a combination mode with these two word groups. 2. We have several data about concreteness and ideality of Huang Di Nei Jing. Subjects and contents in provisions are concrete relatively. But the logical basis of sentences is remarkably ideational. Many kinds of abstract words are used dominantly to compose logics of these basis. It confirms that concrete words can not be used to make theories and concepts in Suwen. Conclusion : I analyzed words related with medical concept and context of paragraphs in Suwen of Huang Di Nei Jing based on concreteness and ideality and I found that the concept and logical system of Huang Di Nei Jing in the objective point of view.

Parameterization of a 3D triangular mesh is a fundamental problem in various applications of geometric modeling and computer graphics. There are two major paradigms in mesh parameterization: energy functional minimization and the convex combination approach. In general, the convex combination approach is wifely used because of simple concept and one-to-one mapping. However, the approach has some problems such as high distortion near the boundary and time complexity. Moreover, the stability of the linear system may not be preserved according to the geometric information of the mesh. In this paper, we present an extension of the convex combination approach based on the mean value coordinates, which resolves the drawbacks of the convex combination approach. This may be a more practical solution because it is able to generate a stable linear system in a short time.

In this study the features expressed by the Korean dresses and its ornaments have been examined through the objects of this thesis, the concept of the pair, under the basis of Korean myths, from which esthetic and spiritual values have been derived. At first, the beauty of the balance pursuing the neatness. Since the pair is made with two piecess, at the time of the placement, the sense of the balance is obtained by the arrangement acccording to the dichotomous principle such as up and down or left and right. Sometimes, the pair could yield the natural pictorial composition, but almost of the time symmetrical composition. This kind of composition is made symmetrical like the structure of the human body, and it is resulted in a neat beauty, which visually presents a harmony, stability and intimacy. At second, the beauty of the harmony in the spirit of the oneness. From the dualistic combination basing on Korean myths, the common features and the significance of the co-existence, obtained from the combination of the pair of the pieces, could be found. By the oneness of the both elements, the creation principle, which is the basic one for a new life, could be established, and the mystery of the creation and the sense of the harmony could be found in it. At third, the wholeness of the completeness concept. The completeness could be felt rather by two than by one, and is provided with a room to be filled with the other one. Consequently, the outer dress is completed with the under dress, and its own beauty could only be made out when the two elements are harmonized. So, it is called as the pair. Like this, the concept about the pair taken roots in the ground of Korean emotions, is basing on the creation principle of the dualistic elements formed from the tradition of Korean myths, and the fact that the mental meaning pursuing the harmony dwells in Korean dress and its ornaments could be confirmed.
