The significance of complexation facilities in Japan is to recognize the problems resulting from social/economic changes such as rapid informatization, globalization, low rates of birth, and aging population, and to strengthen the national competitiveness and urban advantages. Likewise, there have been increasing demands for community facilities that can meet the new requirements in terms of efficient administration and resident-centered administrative service system in line with changes in the society and administrative conditions. Thus, analyzed are cases concerning complex community facilities in Japan that have coped with changes in consciousness in the community earlier than in Korea. Specifically, the concept of modernday complex community facility is investigated, and the complexation of Korea Japan complex community facilities is divided to physical complexation and functional complexation to grasp the types. The complex community facilities are compared, and the characteristics in terms of spatial composition are also examined. The result of analyzing complex community facility cases is comprehensively analyzed to find out new possibilities in this regard.

The purpose of this experimental investigation is to examine the influence of the catheter on local pressure changes and flow rate in an arterial branch model similar to the femoral artery of man. Effects of branch to main lumen flow rate ratios and the locations of catheter tip were found to be significant on the local pressure changes. Relatively large pressure drops due to obstruction effects may induce endothelial cell damage, which have been reported to be the primary cause of the initiation of the atherosclerosis.

In the Fourth Industrial Revolution era, with its accelerating radical changes and innovation, fashion is rapidly advancing to sustain social changes introduced by technological convergence. In light of this, the study investigates the social and cultural characteristics of technologizing fashion products: creative modifications emerge from technological convergence with fashion products and result in a realm separate from technology. By focusing on the nature of fashion, this study analyzes the technologization of fashion products for added value creation in the fashion system. Based on the findings, it interprets different attitudes toward technologizing that changes fashion products. Accordingly, this study reviews previous literature and qualitatively examines empirical cases based on inductive reasoning. In particular, it analyzes commercialized cases of fashion-technology convergence in fashion products found on online fashion media outlets between January 2007 and May 2021, a central period in intellectual and technological innovation. The characteristics of technologized fashion products are identified as follows: expansion of physical functions and categories, interaction with emotional sensibilities, artistry through combination with technologies, and computer-generated imagery(CGI) fashion as digital goods. Therefore, this study analyzes the characteristics of technologization, focusing on the social and cultural properties of fashion products. The findings provide opportunities to understand the paradigm shift of these products that was catalyzed by technologizing.

In the interest of improved automotive fuel economy, one solution is reducing vehicle weight. Achieving significant weight reductions will normally require reducing the panel thickness or using alternative materials such as aluminum alloy sheet. These changes will affect the dent resistance of the panel. In this study, the correlation between panel size, curvature, thickness, material properties and dent resistance is investigated. A parametric approach is adopted, utilizing a "design software" tool incorporating empirical equations to predict denting and panel stiffness for simplified panels. The developed design program can be used to minimize panel thickness or compare different materials, while maintaining adequate panel performance.

Robust design is to identify appropriate settings of control factors that make the system's performance robust to changes in the noise factors that represent the source of variation. In this paper we propose how to simultaneously optimize multiple quality characteristics using the principal component analysis of multivariate statistical analysis. An example is illustrated to compare it with already proposed method.

In this paper, an integrated design of fault detection, diagnosis and reconfigurable control tot multi-input and multi-output system is proposed. It is based on the interacting multiple model estimation algorithm, which is one of the most cost-effective adaptive estimation techniques for systems involving structural and/or parametric changes. This research focuses on the method to recover the performance of a system with failed actuators by switching plant models and controllers appropriately. The proposed scheme is applied to a fault tolerant control design for flight control system.

This paper proposes a shaker system design for acceleration test of gimbal. Main reason of shaker system design is to give acceleration to the gimbal, which is moving and tracking the target on the tracking test equipment. The shaker system is mounted on the tracking test equipment. It uses the scotch yoke mechanism to have the constant movement in return. The Scotch yoke mechanism changes the rotational movement of constant velocity to simple harmonic motion.

This study aims to present the direction of research for rational clothing design and production and improve the productivity of the fashion industry by analyzing the most recent 11 years (from 2010 to 2021) with regard to the clothing construction field. Analyzing the research trends in the field of clothing construction, which is deeply related to clothing production, will suggest the direction of research for clothing design and production. To analyze the current status of research in the field of clothing construction, research trends were analyzed, focusing on 525 research journal articles from six Korean clothing-related journals with terms related to torso and upper and lower limbs. The analysis results of this study are as follows. First, the rapid development of IT technology requires changes and innovations in all processes of clothing construction, including body shape analysis and pattern design. Therefore, it is believed that both body shape and pattern research should be continuously conducted to produce clothes with an excellent silhouette and fit depending on the body shape through studies, such as developing 3D patterns and converting 3D body figures into 2D patterns, among others. Second, since body shape studies are concentrated on young, middle-aged, and the elderly, it is believed that various body shape studies should be conducted on infants and elementary, middle, and high school students who have significant changes in body shape due to changes in the living environment. Third, if the content of pattern research is expanded to various items and is widely conducted, it will contribute to the production of clothing that has an excellent fit. Fourth, at a time when aging in society is accelerating, it is believed that research on patterns and clothing systems that can increase the fit of clothing by analyzing the body types of elderly male and female consumers should be actively conducted. Because the analysis was conducted only among six Korean academic journals, there is a limitation in the expanded interpretation of the results derived from this study.
