This study focuses on the human-centered diversity that is one of the important value in modern society, and the method to apply various demands for architectural space. Human begins pursue new contents and leisurely life all the time and live toward the period of high emotion with personal characteristics. With those social trends, people aggressively request subjects to satisfy their emotional attractiveness as well as comforts and pleasures beyond the functional basic requirements in space. Many studies and projects about emotion have been progressed in the fields of architectural planning and design these days. Purpose: The purpose of this study is to suggest the Multi-Purposed Emotional Space as a new alternative of space renewal that satisfy both functional programs and users emotional demands. Method: For this research, the pervious researches were investigated first to determine essential methodology and terminology to estimate and construct the multi-purposed emotional space. Result: According to survey, the multi-purposed emotional space could finally be classified by emotional words, and the results of experiment were applied for building spaces. By the above process, types of the multi-purposed emotional space and design guidelines could be suggested.

The environment and requirements of modern war fields have been affected and thus changed by a variety of issues. To this end, the development of safety-critical weapon systems frequently need to meet those changes even in the operational phase. The necessity of the changes may be due to the preparation for mass-production or the request originated from the user military forces. To meet such a need can be even tougher in the development of safety-critical weapon systems since the integration of the requirements for both systems design and systems safety would make it troublesome. To handel the matter in this paper, utilization of architecture DB is proposed. Specifically, the situation in demand has first been analyzed and then a problem-solving process to accommodate the design changes has been constructed. In doing so, the concept of the aforementioned integration is particularly focused on the functional architecture, which could be a core concept of our approach to solving the problem. The result of a case study demonstrating the method studied using a computer-aided systems engineering tool is also presented.

The achievement of tissue engineering can be highly depending on the capability to generate complicated, cell seeded three dimensional (3D) micro/nano-structures. So, various fabrication techniques that can be used to precisely design the architecture and topography of scaffolding materials will signify a key aspect of multi-functional tissue engineering. Previous methods for obtaining scaffolds based on top-down are often not satisfactory to produce complex micro/nano-structures due to the lack of control on scaffold architecture, porosity, and cellular interactions. However, a bioprinting method can be used to design sophisticated 3D tissue scaffolds that can be engineered to mimic the tissue architecture using computer aided approach. Also, in recent, the method has been modified and optimized to fabricate scaffolds using various natural biopolymers (collagen, alginate, and chitosan etc.). Variation of the topological structure and polymer concentration allowed tailoring the physical and biological properties of the scaffolds. In this presentation, the 3D bioprinting supplemented with a newly designed plasma treatment for attaining highly bioactive and functional scaffolds for tissue engineering applications will be introduced. Moreover, various in vivo and in vitro results will show that the fabricated scaffolds can carry out their structural and biological functionality.

The Werkbund housing exhibitions in Europe in the 20's and 30's presented various planning concepts and played a important roll for modernization of housing Architecture. This study, therefore, aims to understand the contemporary issues of housing in this period, which showed the meaningful momentum for housing plans today. In order to grasp the general characteristics of exhibition housing the representative cases -Weissenhofsiedlung, Dammerstock, Breslausiedlung, Werkbund Siedlung in $Z\"{u}rich-Neub\"{u}hl$, Werkbundsiedlung Wien und BaBa- were throught documents analyzed. The architects offered an innovative building typology such as row housing and new prototype of housing units accordingly social needs. Especially, In this study housing unitplans were in 6 groups such as flexible type, cabin type, free open plan, Raumplan, functional 2-story type and corridor type categorized. And they were analyzed how deeply technological development, architectural design perceptions as well as functional aspects had on the planning of floorplans reflected. As a result, in the housing exhibitions various architectural ideas presented the "Zeitgeist" not only such as improvement of physical environment of housing, but also such as rationalization, standardization, functionalization, normalization of housing architecture. Also their unitplans corresponded to newly developed building typology and modern household type. As well as they represented notable spatial concepts. Moreover it contributed to create a new paradigm of housing for the new epoch.

This study examined the political, social, and historical characteristics of the Great Mosque of Algiers, alongside its functional, spatial, and symbolic aspects. Generally, mosques are buildings where religious expression is profoundly intense, making it challenging to apply new types and designs. However, the Great Mosque of Algiers successfully inherits traditional Islamic features while simultaneously embodying modernity at an international level. The results of the multifaceted analysis of the convergence of tradition and modernity in this contemporary architectural work are as follows: First, through research on Islamic architecture, the study identified the functional and spatial characteristics expressed in Islamic buildings. In particular, the study highlighted the features of the Külliye as a multi-use building complex and provided a detailed analysis of symbolic elements such as minarets, domes, ablution facilities, and mihrabs, which are strongly emphasized in mosques where religious features are prominently displayed. Second, the analysis of the Great Mosque of Algiers' architectural plan explored the inte-gration of tradition and modernity. Traditional elements are akin to the identity of the building and contribute to its overall value. Third, by examining the development process of the Great Mosque of Algiers project, the study analyzed the international cooperation required in the modern era, understanding the hybrid nature of this architectural project.

This study proposes a construction plan for the Korea Navy's next-generation TSCE(Total Ship Computing Environment) based destroyers to address rapidly evolving maritime threats and decreasing military manpower. It focuses on system integrated ship construction based on TSCE for quick response time with fewer operators, improving the efficiency of systems and Equipments installed in the ship. The methodology includes analyzing TSCE-based system integration theories and levels. also analyze system integration in U.S. Navy's Zumwalt destroyers and Littoral Combat Ships, conducting expert surveys to build consensus on system integration methods, proposing operational efficiency improvements through TSCE-based system integration. Additionally, we propose an architecture of TSCE with real time OA(Open Architecture) from both functional and physical perspectives, verified through Python simulations. The study suggests optimal crew sizes for next-generation destroyers through comparative analysis of TSCE based integration types. It emphasizes the importance of system integration in naval ship construction, presenting specific measures to enhance operational efficiency and optimize crew operations. The findings are expected to contribute significantly to enhance the future naval capabilities of the Korea Navy.

기존 건설업은 타 산업 분야에 비해 생산성이 낮은 산업에 분류된다. 건설업의 생산성 저하를 해결하고자 전 세계적으로 기존 건설 방식보다 약 40% 생산성이 높은 오프사이트 건설(Off-Site Construction; OSC)에 집중하고 있다. 이러한 높은 생산성이 가능한 이유는 공장에서의 부재를 생산, 현장으로의 운반, 현장 조립 3단계를 연속적인 흐름으로 일관되게 유지하기 때문에 가능하다. 본 연구는 문헌고찰, 1차 사전 현장답사, 2차 온라인 설문, 3차 전문가 심층인터뷰를 통해서 기능조사를 수행하였다. 조사된 기능의 항목들을 편의성, 유연성, 관리 용이성, 의사소통, 안전성 5가지로 분류하였으며, 해당 기능특성에서는 유연성, 관리 용이성, 의사소통이 높은 점수를 나타내었다. 이는 건설현장의 공사 진행에 따른 변화, 공장의 생산일정, 운반 소요시간과 같은 다양성으로 인해 유연성, 관리 용이성, 의사소통이 중요한 기능특성으로 반환된 것으로 판단된다. 마지막으로 설문 조사된 기능 점수 결과에서 평균 점수 4점 이상에 해당된 기능 15개를 바탕으로 Functional Block Diagram을 구성하였다. 본 연구를 통해 OSC 운반 시스템이 구축된다면 성공적인 건설 OSC 프로젝트에 기여하고, 생산성을 높일 수 있을 것으로 판단된다.
