본 논문은 웹 애플리케이션의 증가로 인해 소프트웨어 내 보안 취약점을 이용한 사이버 공격이 증가하고 있다. CSRF(Cross-Site Request Forgery) 공격은 특히 웹 사용자와 개발자에게 심각한 위협으로, 사전에 예방해야하는 공격이다. CSRF는 사용자의 동의 없이 비정상적인 요청을 통해 공격을 수행하는 기법으로, 이러한 공격으로부터 웹 애플리케이션을 보호하기 위한 방법은 매우 중요하다. 본 논문에서는 Spring Security와 Apache Shiro 두 프레임워크를 통해 CSRF 방어에 대한 성능을 비교 분석하고 검증하여, 효과적으로 적용 가능한 프레임워크를 제안한다. 실험 결과, 두 프레임워크 모두 CSRF 공격 방어에 성공하였으나, Spring Security는 평균 2.55초로 Apache Shiro의 5.1초보다 더 빠르게 요청을 처리하였다. 이러한 성능 차이는 내부 처리 방식과 최적화 수준의 차이에서 비롯되었으며, 시스템 자원 사용 측면에서는 두 프레임워크 간에 차이가 없었다. 따라서 높은 성능과 효율적인 요청 처리가 요구되는 환경에서는 Spring Security가 더 적합하며, Apache Shiro는 개선이 필요하다. 이 결과는 웹 애플리케이션의 보안 아키텍처 설계 시 중요한 참고 자료로 활용되기를 기대한다.

시로아비앙가는 인도의 고대의 의학서이면서 건강관리의 지침서인 아유르베다의 한 시술법이다. 본 연구는 시로아비앙가가 스트레스 완화에 미치는 효과를 20대 여성을 대상으로 살펴보았다. 이 실험은 뇌파측정을 통해 알아보았는데, 시로아비앙가 마사지가 좌뇌의 델타파와 우뇌의 델타파, 세타파를 떨어뜨리고, 우뇌의 알파파와 SMR파, 로우베타파는 증가시키는 것으로 나타났다. 수면 시에 나타나는 델타파와 세타파가 깨어있을 때 높게 나타난 것은 대상자가 스트레스와 긴장상태에 있음을 의미하고, 시로아비앙가 마사지 이후에 델타파와 세타파가 감소하는 결과는 긴장상태가 완화됨을 나타낸다. 뇌가 활동하고 있을 때 나오는 알파파는 심신이 이완되어 편안할 때 가장 많이 나오는 뇌파이다. 따라서 알파파가 시로아비앙가 마사지 후 증가하는 점은 시로아비앙가 마사지가 스트레스 완화에 영향을 미침을 알 수 있다.

This study examined concepts and expressional relations with Rene Maggritte works that had influence upon design expressions of Shiro Kuramata who brought name of things to the extreme to give new values and functions at the end. Rene Maggritte who was a representative surrealism painter in Belgium had a lot of influence and inspiration on the art world including pop art and conceptual art in the middle of the 20th century and so many modern artists. Rene Maggritte unreasonably placed object of ordinary things that people could know to combine them and to make people's thought be free from ideas. Shiro Kuramata worked at wide areas including the space, lighting, furniture and products to be well known as a designer who could create concepts. Shiro Kuramata designed indoor space and furniture not by making forms but by being free from customary names and concepts of things to examine substance and to discover unlimited possibility and to create new visual functions. And, such a thing made people be free from names and concepts that they cognized for a long time, and it brought freedom to things. This study investigated correlations of work concepts and expressions of Rene Maggritte and Shiro Kuramata to bring new inspiration and expansion to people's thought methods and design methodology regarding concepts of things.

This study aims to inquire into the expressive characters of Shiro Kuramata's works regarding his design languages. His design languages, based on sentimentality and aesthetics characteristic of the orient and his unique memories and experiences, can be defined as nongravitation, fioatation and transparency. And the definition can be completed by his unique extinguishing technique, eliminating the structure with materials without feature, such as glass and acrylic and expanded metal, steel mash and 'Star piece Terrazzo' a material which he has invented. This study examines Shiro Kuramata's design works from the late 1960's to 1991, the year of his death, the background of his growth and the art and people who have influenced him. It also looks into the indigenous cultural background and his unique memories and experiences. The study also considers his furniture works and interior design to read his languages properties of the materials and expressive techniques. The study presents data on Shiro Kuramata and puts forwards the significance of his works and tries to lead the way of the interior design by application techniques of materials.

Kuramata Shiro's design has been evaluated as an unseen type of beauty. He created totally different aesthetics from functional furniture by utilizing glass, acrylic, and expanded steel mesh which usually are inappropriate for making furniture. Kuramata told that his design always starts from zero status. By doing so, he could be free from the existing notion and form of furniture. This means that every function and every form must be based on his own understanding and experiment in order to produce newness. Owing to these efforts, we can regard his design as artworks. Kuramata tried to bring forth formative lines inside contour of furniture rather than to deform only the formal outlines of furniture. These lines are very delicate and sometimes ephemeral. But they establish formal potentiality of phenomenological being of beauty. Also those lines are built from humble industrial material but they open the truth of thing itself and introduce the beauty to field of aletheia. At the same time, transcending limitation of function and use, they leave pure form and temporariness. So, lines become a field of Heideggerian rift which produces embodiment of form. We can appreciate his design through these lines that are relatively thin but vivid enough to follow his original world of art.

The purpose of this study is to define concept and characteristics of "Unphenomenon", the design concept conceived by Shiro Kuramata who is a world renowned Japanese interior designer and to explore how his ideas were materialized in his works. This study 1) examines his experience during his childhood reflected in his essay The scenery of the Unphenomenon' and training in Kuwazawa Design Institute that made Shiro Kuramata a true interior designer, and also considers how his design philosophy had been built up and realized under the unique social situation at the time. 2) defines the concept and characteristics of "Unphenomenon" as substance of his design philosophy by surveying remarks in his books and comments made by people around him in press interviews. 3) concludes his own design method and uniqueness by analyzing his works based on them. As a result, the study has founded that 1) transparency as recognitive realization of existence and non-existence: non-existence of physical property, connotation, ambiguity 2) expression of uncommonness by correcting and reinterpreting common prejudices: flotation, distortion of scale and shape 3) realization of insubstantiality by removing and replacing material and shape: replacement into light, removal of the structure, multiple layers of meaning.

This study aims to inquire into the expressive characters of Shiro Kuramata's works. Kuramata, who was active between mid of 1960's to 1990's, went beyond the limits of range of the eastern world, is known internationally. His design philosophy is influencing the current design world greatly. To understand his background and to reexamine his characteristics suggest to us various materials and design languages to be seen forms and principles of his works. I presents data on Shiro Kuramata and puts forwards the significance of his works and tries to lead the way of the design by application techniques of materials on this study.
