Installing accelerometers in a building is an effective way to know how the building shakes when an earthquake happens. In this paper, we will introduce an example of an analysis that captures the acceleration reduction effect of the vibration damping device using data observed by the accelerometer at Roppongi Hills Mori Tower in Minato-ku, Tokyo, during the Great East Japan Earthquake on March 11, 2011. Moreover, as the latest effort, from the standpoint of a developer who builds and operates a number of high-rise buildings in Japan, where frequent earthquakes are experienced, a system for real-time processing of accelerometer data was developed to instantly diagnose the degree of damage to high-rise buildings, and the actual system of earthquake damage health monitoring is discussed. This system is currently in operation in twelve high-rise buildings including Roppongi Hills Mori Tower.

Design of an in-process feedback control system has been studied for precision grinding. A grinding system consists of a grinding tool, a turn table and a disk-shaped workpiece on the table is taken as an object. A grinding process model has been deduced which gives some reasoning about the process errors. In the control system the tool position is actively controlled by an electro-magnetic actuator in-process. The ground error is feedback to compose a closed-loop control system and an optimal PID controller is applied. Some control performances such as transient response and disturbance such as transient response and disturbance attenuation have been examined, which convinces the effectiveness of the control. Some methods for implementation of the control. Some methods for implementation of the control have been suggested from a standpoint of practical application.

E-learning systems have proliferated in recent years, particularly in the wake of the global COVID-19 pandemic. For kids, there isn't a specific online learning platform available, though. To do this, new conceptual models of training and learning software that are adapted to the abilities and preferences of end users must be created. Young pupils: those in kindergarten, preschool, and elementary school are unique subjects with little research history. From the standpoint of software technology, young students who have never had access to a computer system are regarded as specific users with high expectations for the functionality and interface of the software, social network connectivity, and instantaneous Internet communication. In this study, we suggested creating an electronic learning management system that is web-based and appropriate for primary school pupils. User-centered design is the fundamental technique that was applied in the development of the system that we are proposing. Test findings have demonstrated that students who are using the digital environment for the first time are studying more effectively thanks to the online learning management system.

Until now, product mostly has revealed physical quantities created by the standpoint of engineers. Consumers, however, perceive and evaluate products on the non-physical characteristics, such as feelings, emotions, and experiences in different social and cultural situations. Especially, for the household appliances such as a refrigerator, the sound is heavily related to the satisfaction of a customer who is a real user of the product and is very important factor to decide purchasing as well as visual design. Therefore, in this research, not only the simple sound pressure level but also the consumer's sense of hearing evaluate the noise from the refrigerator. And also, in order to improve the quality of sound through the design change, the consumer's evaluation is analyzed and related to the engineering quantities.

현재 출판계는 'U-출판', 라틴어로는 '유비쿼터스(Ubiquitous)출판' 시대를 맞이하였다. 책의 개념이 전통적인 종이책(paper media book) 개념에서, e-북 개념을 넘어 U-북 개념으로 발전하고 있다. 그러나 시대에 따라 매체에 따라 책의 개념이 바뀌어도 변하는 디자인적 가치와 변하지 않은 디자인적인 가치가 있다. 이러한 관점을 즉시(the immediate)와 항상적(the ultimate)가치라고 할 수 있다. 즉시(the immediate)는 시대정신을 표현하는 현시대의 가치를 의미하고, 항상적인 가치는 디자인을 전달하는 매체의 차이에도 불구하고 시대를 초월하여 변하지 않는 것을 의미한다. 본 연구에서는 2005년부터 시작된 U-북 개념의 디자인을 즉시와 항상적인 가치의 관점에서 연구하고자 한다.

This study is to examine the modern women's awareness make-up in psychological standpoint based upon the survey of $20\~30$ years old women's consciousness of the motivation, the attention, the psychological utility, the attitude for make-up, the action behavior and the coordination with clothes. Modern women show a keen interest in make-up in company with the diversity of a fashion. This means the tendency which the intention for change and the expression of oneself are emphasizing on. The motivations of make-up are women's attention to other people and notice of evaluation of others and social meaning of make-up in relation with one's interest in appearances. Also, total coordination is concerned as another motivation. Make-up became the practical use and usual doings for women with the diversity of the information of make-up & the increase of cosmetics. Since there were so many women responded that they start to make up in their teens, we recognized that the women's sense of values has changed with the change of modern society.

While the existing feng-shui is largely approached architecturally and geographically as positive place and negative place, the study is characterized by approaching and analyzing poong-soo environmentally. The theory of Eco-city as one of modern-city theories is worthy of studying by analyzing the merits and demerits of it and combining it with poong-soo and making a new alternative theory. Theory of Natural Energy and principle of Natural Balance. Thus, poong-soo ideas can be an important view of nature in analyzing the theory of Eco-city which is coming to the front these days. In particular, we try to make use of poong-soo as a basic theory for a city planning and design by studying and analyzing and combining the merits and demerits of Eco-city with poong-soo and presenting a new alternative method of a stable and balanced "refined city development". On the other hand, we connect 'theory with practice(or experience)' by covering all spaces variably from minimum unit space to city-space from the standpoint of poong-soo. But, problem of the Theory of Eco-city from the view of poong-soo are too artificial and theoretical, even if ideal. Conversely, from the view of Eco-city, the possibility of the practicability of Korean poong-soo is judged to be high. we can tell that among capital cities applied by poong-soo, historical cities like Beijing in China, Seoul in Korea and Tokyo in Japan are poong-soo cities in accordance with the requirements of Eco-city.

In today's world where a preference for prestigious brands prevails, it's essential to have creative design conceptions rather than try simple mimicking or following in order to be recognized for creative and objective design works. In that sense, the development of clothes design using construction lines offers a great approach towards the ideas of reinterpreting and creating new designs since it creates new forms by understanding lines as signs of conception and transforming them. That approach allows a designer to improve his or her imagination, creativity and expression in a freer and richer manner, think of many original ideas through diverse changing processes, and develop the skill to visualize the ideas by incorporating geometric forms of abstract lines into clothes. When approaching the conception of clothes design from the standpoint of construction lines, you need to adopt more specific and systematic design methods instead of vague imagination to introduce simple facts or theories to a new design process. That's one of the ways you can approach clothes design easily and enhance your conception skills. The process of clothes design according to the conception of construction lines is composed of the following stages; the preparation stage involves an understanding of the principles and the entire process of clothes design conception based on construction lines; the idea stage requires a designer to make free alterations of the given basic construction lines by moving and replacing the lines and sides in diverse ways; in the creation and expression stage, the designer uses the newly reconstructed construction lines to create clothes design; and in the evaluation stage, the designer makes a presentation of his or her subjective design works and has his or her works assessed and tested in an objective fashion. In today's modern society that demands new and original globalized design, the results of the study will help to invigorate the development of new fashion design in a more systematic and practical manner by suggesting a feasible and gradual educational program for the development of design based on the technique of construction lines.

In 1990s, the necessity of the Korean contemporary medium/small scale gallery as a place of experience rather than that of simple viewing has increased to meet from the requirements of the pluralistic and popularized society. The gallery makes efforts to form a collective street to cope with the influential of the power large scale cultural space as well as finding a novel direction in order to derive the regional sympathy in connection with the culture space of the neighborgood. In this paper, we study the 1990s Korean medium/small scale gallery in two aspects: First, the architectural techniques and elements which are introduces the audience to both interior and exterior spaces constructed by the 1990s gallery architecture, are investigated. The conventional architecture shows the blocking of the neighborhood and the trend of severance when viewing from both the architectural and the civil points. Secondly, we present the design characteristics from the several points of view such as conceptual, spacial, visual angles. The various trends of works in exhibition of the fine arts can provide a means for producing a great deal of variation in recent gallery architecture when viewing from a stage standpoint of exhibition space.
