In smart era, concept of User experience has been an important issue both in academic and practical areas in recent years. Interactive space became one of the major design paradigms. For elevating the interactive effect, we need user?centered design methodology which uses the influential factors on the interactivity. As, well developed information technology made a lot of changes to various fields of our society, interactive space with the concept of HCI became a big issue in environmental design field. In this interactive space, various types of informative factors of the given space are sent using sensor and computer networking technology to the main system. So, a user's movement in the space in more than just a movement itself-user's movement now forms a important spatial structure that leads the narrative of the space. in this research, I will come up with the problems that the interactive space has right now, and analyze what the public space must have, and combine them with interactive space by HCI theory. architecture space is not the old space adapting digital technology. In order to take the role as new space paradigm. environment and technology, it has to develop technology continuously and experimental space at the same time. It must have co-evolution of architecture space field and others through organic network. by that, the evolution of space will be in the way that combines space which is responded to human emotion and user centric human friendly.

Vehicle body frame stiffness affects the dynamic and static characteristics. Vehicle frame structural performance is greatly affected by crossmember and joint design. While the structural characteristics of these joints vary widely, there is no known tool currently in use that quickly predicts joint stiffness early in design cycle. This paper presents the joint design factors affecting on low frequency vibration. The joint factors are joint panel thickness, section property, flange width and weld point space. To study the effect on vehicle low frequency vibration, case studies for these factors are performed. And Sensitivity analysis for section property is performed. The result can present design guide for high-stiffness vehicle.

This study aimed to derive the concept and types of school outdoor spaces in Seoul. The research results showed that the concept of school outdoor space can be viewed as an outdoor activity space in schools that secures the value of integrated public life and communal life, including "behavioral rights, walking rights, living rights, urban rights, landscape rights (viewing rights), and nature experience rights." It can also be defined as a basic educational space that reflects the value of education, which is the basic function of schools and the characteristics of the community. As a result of the analysis based on the general types of outdoor spaces, it was found that the outdoor spaces of Seoul schools can be divided into three major categories: walking space (movement function), educational space (educational activities), and rest and other spaces (other services). Based on this, outdoor spaces were categorized and subcategorized to serve as the basis for policy implementation. These classifications are characterized by 1) simplifying the classification of spaces by function into three (movement functions, educational activities, and other services) to enable the use of outdoor spaces for integrated purposes; 2) reflecting the complex use of spaces by subdividing educational spaces focusing on major activities, and in particular, discovering complex spaces due to the three-dimensionalization of buildings; and 3) enabling spatial-level planning and facility element-level access according to school characteristics. It is characterized by applying the recent trends and systems of general outdoor space projects to the current situation of schools.

Furniture should change according to space. Therefore, it is important that the flexibility of the furniture, the functional efficiency, the economical efficiency and the convenience of the furniture of today. These characteristics are also important for seminar tables that are used temporarily by a large number of people. The seminar furniture currently in use has no shielding plate, there are two forms of table and shielding plate folding table. Therefore, in this research, furniture design and product development that can complement the shortcomings of the seminar furniture currently in use were done. Analysis of problems through overseas investigation and domestic market research, design planning and design, and prototyping. We have sought to optimize the volume by applying the characteristics of RTA furniture to develop a lightweight, lightweight, lightweight, easy to install and easy to use shielding plate, and open and closed system. Basically developed two types of shielding board seminar table basic shape and Roll Screen type, we expanded the scope of application such as each color and pattern. In order to reduce the weight, we replaced the parts such as anchor bolts and hinges and the shielding plate with Roll Screen and pursued volume optimization. As a result of this research, it is expected that the system of mechanisms such as packaging standardization and damage prevention for weight reduction and volume optimization will contribute to building competitiveness by domestic office prefabricated furniture industry's original technology.

After its experiment involving the exploding of a satellite in space in 2007, China proudly aired news on TV and ran articles in newspapers. However, the event was internationally criticized and drew widespread attention. Many countries denounced the explosion by pointing out that it could be part of the nation's plan to expand its military power to space or that it could pose a danger to the peaceful use of space. However, there is no talk of whether the experiment that produced a huge amount of space debris could have violated an international law, namely the Outer Space Treaty. Although space garbage has been said to be a serious problem, the amount is still on the increase. If we continue to launch new space launch vehicles into orbit at this rate, we will not be able to use it anytime soon like we do today. As the commercial use of space is likely to increase, the situation will certainly get worse. The international community is fully aware of the seriousness of the problem and working together to reduce the amount of space garbage. However, despite the fact that the United States and Soviet Union's ASAT(Anti-Satellite) programs have been implemented for a long time, there have been no complaints about them in terms of military expansion or breach of the Outer Space Treaty. Also, the recent Chinese test is largely viewed to be in accordance with international law. A lot of research has been undertaken with regard to the problem of space garbage. Now people's awareness of dangers being posed has been fully raised. Under the circumstances, the dismissing of China's satellite smashing, leaving a big mess in its wake, as nothing more than an experiment, is a red flag to, if not many, at least some people. By means of this thesis, I would like to review whether the Chinese test has violated an international space law. This thesis presents an overview of the issues surrounding the event and examines the possibility of violating the Outer Space Treaty, formally the Treaty on Principle Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies. After the China test, the UN Scientific and Technical Subcommittee first adopted space debris mitigation guidelines, I'll introduce the content of the guidelines and discuss the characteristics of the guidelines and what can be done to address the issue.

Local governments play a critical role in achieving carbon neutrality and reducing national carbon emissions. To manage carbon emissions effectively, it is essential for local governments to analyze regional carbon emissions. In this study, we developed a model for estimating carbon emissions based on land use and analyzed regional characteristics of carbon emissions to suggest policies for achieving carbon neutrality at the regional level. Our model for calculating carbon emissions is based on an analysis of the activities that contribute to carbon emissions for each land use, and we established the spatial scope of carbon emission calculation. We applied this model to the cities and counties in Gyeongsangnam province, calculating carbon emissions from settlement and agricultural production activities and comparing regional characteristics of carbon emissions. Our analysis showed that areas with larger populations generally produced higher emissions in all categories, but we observed different results in terms of unit emissions, emissions divided by area, population, and household. Based on these findings, we propose policies such as increasing the generation of new and renewable energy using public institutions, promoting the conversion to cleaner cooking and heating energy sources, and encouraging the adoption of eco-friendly automobiles on roads. We believe that our analysis of the spatial and regional characteristics of carbon emissions can help local governments establish effective policies for reducing carbon emissions in their regions.

This study intended to provide basic data for the future naming of outdoor areas in apartment complexes by conducting research into the causes, lengths of time, trends, and characteristics of the changes of outdoor space names of apartment complexes and by analyzing current images of outdoor space names. In order to explore the causes and intervals of changes of outdoor spaces in apartment complexes, related literature was surveyed, with on-site inspections being made to examine outdoor space names by time intervals. At the site selected for this study, a case study was conducted to determine the outdoor space names and to understand the trends in the changes of these name in the apartment complexes. Moreover, a questionnaire survey incorporating selected adjectives was administered to investigate the perceived images of outdoor space names and finished construction spaces. The results are as follows: 1. Causes driving changes in apartment outdoor space names included changes in apartment complex planning concepts, changes in the values and demands of apartment buyers, social values, and changes of brand. Intervals of changes were divided into two with the 1997 IMF financial restructuring of the Korean economy as the division. 2. In regards to trends in changes of apartment outdoor space names and their characteristics, various features applied to spaces have caused many changes, which resulted in the phrase $'\bigcirc\;\bigcirc+garden'$, expressions suggesting various images, and Korean names. 3. The results of the analysis of apartment outdoor space names and finished construction images revealed that there was a difference in all the spaces. This is thought to be mainly due to such issues as paved min, the use of ready-made goods, and figurative expressions. The results of the study above indicate that changes in outdoor space names of apartment complexes have been made simply as part of marketing strategies, with no consideration of the residents. Apartments, an important means of housing in Korea, account for more than 50% of Korea's total housing, and the naming of outdoor space serves as an essential element for residents. Therefore, outdoor spaces of apartment complexes should be named in consideration of the final appearance after construction is completed, with effort by the industry being required.

Architectural works build with a modernistic viewpoint led to standardization and low of peculiarity , and which resulted in isolation of people from their environment. In that context, the sense of place can be a new paradigm replacing modernism and reflect the fundamental value and meaning of architecture. Interior space as a place can be analyzed from the viewpoint of existentialism. The purpose of this research is to define the concept of place based on C. N. Schulz's theory of space, and aims at embodiment of the sense of place in interior, especially residential , environment through applying emotional and psychological factors. Spatial characteristics that help to form and enhance the sense of place are center, axis and direction, and boundary and enclosure. Some psychological factors, in other words, people's psychological needs, affect the continuation of the sense of place, especially in residential environment where we reside comparatively for a long period and use the same place repeatedly , security, hierarchy/order, aesthetics, variety, and sociability. The sense of place is embodied and lasted mainly by personalization through the process of visualization , symbolization , and complementation of above mentioned properties and elements.
