In these days, restaurants are not simply used as a physical space but used as a cultural space in which people can enjoy and experience different cultures and traditional images. Moreover, from the restaurants design elements which help to form the atmosphere of the restaurants which serve food of specific country, we can see the history and traditions of that country. The additional value of the traditional decorative components which are the main factors forming the atmosphere of the restaurant will be different according to the various expressions used in the restaurant space. For this article, 12 restaurants, Norangjugory korean restaurant, Yongsusan korean restaurant, Best well-bing food restaurant, Awoolim, Mugunhwa, Ondal in Korea, and Songhelou, South Beauty, Xuxian restaurant & lounge, Beijing dadong roast duck restaurant, The horizon chinese restaurant, Dynasty jade garden in China, were selected for the field study. This study focused on a comparative analysis of the traditional decorative elements, especially, the application rate of the traditional decorative elements. The analyzed elements are nature, religious beliefs, history and culture for the intangible elements and facade, courtyard, trademark, ground, wall, ceiling, door, window, furniture and adornment for the tangible elements. After that, we analyzed the rates of the use of traditional decorative elements and modern decorative elements. Through the survey result and ratio analysis, we concluded as below. In Korean restaurant, traditionality is expressed in furnitures while, in Chinese restaurant, traditionality is expressed in decorative pattern. When it comes to the intangible elements among the traditional decorative components of the Korean and Chinese restaurants, Chinese and Korean restaurants have similarities in emphasizing the natural elements. Korean restaurants focus much on the environmentally friendly parts, while Chinese restaurants focus much on the fantastic natural atmospheres like those shown and expressed in the poems. As for religion characteristics, Chinese restaurants emphasize "geomancy" more than Korean restaurant. When it comes to the visible elements among the traditional decorative components of the Korean and Chinese restaurants, in Korean restaurants, the interior part has more traditionality than exterior part, while in Chinese restaurants, the exterior part has more traditionality than the interior part.

The purpose of this study is to review and validate the seismic analysis procedures of turbine-generator foundation specified in the Korea Building Code which adopts equivalent static analysis. Typical machines and foundations were chosen and various kinds of parametric studies were peformed and the results were compared with the detail dynamic analysis. The general trend of the study results showed that the most of the computed responses of equivalent static analysis are smaller than those of the dynamic analyses(response spectrum analysis and time history analysis), which implies the existing seismic analysis technique using the existing Building Code may give unconservative design results. The results also showed that the seismic loads are one of the governing design parameters of the turbine-generator foundations.

This study was carried out to review the characteristics of the Swedish modern furniture design and the works of Bruno Mathsson, who is appreciated as one of the most important furniture designers in the history of modern Swedish design. First, the authors examined how the Swedish designers set the value of warm, graceful humanity, practical simplicity, and the traditional craftsmanship in their furniture design with modernist ideology. Second, by examining the range of Bruno Mathsson's works from the 1930s to the 1980s, the authors searched for how these works show the realized models of the ideals of Swedish modern furniture. In this, this article explains that Mathsson's works and the modern Swedish furniture could have been regarded and beloved as being innovative and modern for more than 50 years for their friendliness to human body by the ergonomic structure and to human feeling by the quality of natural materials and finishes. In addition, their consistent effort to adopt traditional craftsmanship into functionalist ideals of modern design shows how these furniture designs could have keep the lasting quality in the life of people in different time frames.

최근 우리나라에서는 건축적 또는 사회적 요구로 비정형 고층 RC건물이 급증하고 있으나, 이와 같은 건물을 내진설계하는데 요구되는 지진의 방향성과 직교성을 적응하기 위한 구체적인 방법이 제시되어 있지 않아 설계자들이 설계하는데 어려움이 있다. 따라서, 본 논문에서는 우리나라에서 실제 건설된 비정형고층 RC건물을 스펙트럼해석법과 시간이력해석법에 따라 SAP2000을 사용하여 동적해석을 수행한 후, 하부골조 기둥의 설계력을 비교함으로써 주축의 설정과 지진의 방향성을 고려하는 것이 설계력에 미치는 영향, 그리고 방향성과 직교성을 모두 만족시킬 수 있는 방법에 대해 연구하였다. 연구결과 내린 결론은 다음과 같다. 1) 지진에 직각방향 전단력이 발생하지 않는 방향을 주축으로 정의하여 설계부재력을 구하면, 동적밑면전단력 보정계수가 감소하기 때문에 X, Y축을 주축으로 정하여 설계부재력 구하였을 때보다 설계부재력이 $15\%$정도 작은 값을 보여주었다. 2) 100/30법에 따라 방향성을 고려하여 구한 설계부재력은 2방향 시간이력해석결과로부터 구한 최대설계부재력보다 큰 값을 보여주어 100/30법에 따라 직교성을 고려하는 방법은 타당한 것으로 나타났으나, 시간이력해석결과에서 부재력을 나타내는 벡터$(P,\;M_y,\;and\;M_z)$ 많은 부분이 100/30법에 따라 예측한 설계부재력의 영역을 벗어났다.

Now that problems with force-based seismic design have been clearly identified, design is inclined toward displacement-based methods. One such widely used method is Direct-Displacement-Based Design (DDBD). Yet, one of the shortcomings of DDBD is considering higher-mode amplification of story shear, moments, and displacements using equations obtained from limited parametric studies of regular planar frames. In this paper, a different approach to account for higher-mode effects is proposed. This approach determines the lateral secant stiffness of the building frames that fulfill the allowable inter-story drift without exceeding the desired story displacements. Using the stiffness, an elastic response spectrum analysis is carried out to determine elastic higher-mode force effects. These force effects are then combined with DDBD-obtained first-mode force effects using the appropriate modal superposition method so that design can be performed. The proposed design procedure is verified using Nonlinear Time History Analysis (NTHA) of twelve planar frames in four categories accounting for mass and stiffness irregularity along the height. In general, the NTHA response outputs compared well with the allowable limits of the performance objective. Thus, it fulfills the aim of minimizing the use of NTHA for planar frame buildings, thereby saving computational resources and effort.

In order to discuss identity of Interior Design as an academic study, I analyzed educational objectives and curriculums of Interior Design in tertiary educational institutions. To this end, I surveyed 83 colleges and categorized those colleges based on their school system and academic field where the college is included. First, according to the school system I classified them into 2-, 3-, 4-year course. Then, I categorized each of them into subcategories based on their fields; 2 year course into Design field and Construction Engineering field, 3 year course into Construction, Engineering and Design, 4 year course into Design, Life Science, Engineering and Construction. Referring to a Classified table of majors and fields by KIID, I reorganized them into ten big categories: (1)Design Theory (2)Design Technique (3)Interior Composition Elements (4)Basic Practice (5)Advanced Practice (6)Psychology and Behaviour (7)Design Management (8)History of Interior Design (9)Digital Design (10)Communication. The afore-mentioned ten curriculum categories show characteristics formed by composition in each school system. The curriculum categories in school system had differences in composition depending on each field. By examining similarities and differences among them, I concluded attributes of each field. I hope the result of this study can contribute to consistent study to establish and develop the academic identity of Interior Design.

This study aims to investigate the physical characteristics and architectural ornaments of the walls (DamJang) and their bordering area that defines the Rear Garden of Changdeok-gung, one of the Royal Palaces in Seoul. This area, centered on Buyong-ji(부용지) and Aeryeon-ji(애련지), features the morphological diversity of buildings, walls, gates and stone bases in the palace. The findings are summarized as follows: First, DamJang, as a basic architectural element for the space organization, takes a set of various forms featuring different construction materials while responding positively to the physiographic nature of the surroundings; Second, DamJang along with their gates, also features different types of ornamental expressions which also suggest the hierarchy of its building and space; Third, typical of the traditional garden design in Korea are a group of DamJang standing as independent structures mostly around Buyong-ji and Aeryeon-ji whose finishing conditions also differ based on the nature of the space; Fourth, among commonly observed examples of DamJang in the Rear Garden and Changdeok-gung palace-wide, is a 'T' shaped wall whose heights and materials function as a design element for the garden.
