A new solution procedure for approximate reanalysis, using the staged hybrid methods with substructuring, is proposed in this study. Displacements are calculated with two step mixed procedures. First step is to introduce the conservative approximation, which is a hybrid form of the linear and reciprocal approximation, as local approximation. In the next step, it is combined with the global approximation by reduced basis approach. Stresses are evaluated from the displacements by matrix transformation. The quality of reanalyzed quantities can be greatly improved through these staged hybrid approximations, specially for large changes in the design. Overall procedures are based on substructuring scheme. Several numerical examples illustrate the validity and effectiveness of the proposed methods.

Reinterpretation of the visual characteristics of Korean folk painting in contemporary Korean painting is to seek directions of today's Korean painting. When examining expressions of contemporary painting we see that there is a reappearance of iconic images, a reinterpretation of both flatness and multi-perspectives, and an objectifying of pastiche folk icons with an experimental spirit. All of these techniques suggest methods of contemporary Korean painting through 'folk painting'. Although folk painting has been adopted in contemporary Korean painting for a long time, interest increased in the 1980s. With the prevailance of both national characteristic expressive techniques of realism and color painting, artists reinterpreted folk painting in their work, borrowing the traditional five colors, common contents, and iconic images. Particularly, an interest in 'Korean Beauty' drew people's interest back to folk painting which provided the significant 'Korean Beauty' of traditional expressive techniques. This study is to examine the characteristics of selected group of works that created a new expressive technique in today's Korean painting by either the reappearance or the reinterpreting of iconic images of the Chosun Dynasty's folk painting. To achieve these goals, the artists, who modify or reinterpret folk painting's visual characteristics with a contemporary sense, are divided into three categories in this study; 'The Readoption of the Folk Image', 'The Reinterpretation of Folk Characteristics', and 'Experimental Expressions'. As a result, it proves that folk painting is both a classical expression and national expression which was not only favored in the Chosun period, but also can be reinterpreted through today's visual methodology.

In this study, an optimum design algorithm using efficient reanalysis is proposed for seismic design of Reinforced Concrete (RC) piers. The proposed algorithm for optimization of RC piers is based on efficient reanalysis technique. Considering structural behavior of RC piers, the other approximation technique such as artificial constraint deletion is introduced to increase the efficiency of optimization. The efficiency and robustness of the proposed algorithm including the proposed reanalysis technique is demonstrated by comparing it with a conventional optimization algorithm. A few of design examples are optimized to show the applicability of the proposed algorithm.

This study concerns with partial sum of Fourier series, Fourier coefficients and the $L^1$-convergence of Fourier series. First, we introduce the $L^1$-convergence results. We consider equivalence relations of the partial sum of Fourier series from the early 20th century until the middle of. Second, we investigate the minor lineage of $L^1$-convergence theorem from W. H. Young to G. A. Fomin. Finally, we compare and reinterpret the $L^1$-convergence theorems.

Design-oriented approximate structural reanalysis models are compared and assessed, particularly with focus on the case of large changes of design variables. The effectiveness and reliability are demonstrated by means of numerical examples. The results of the study suggest the following conclusions relative to the potential of the procedures. (A) local approximation is only appropriate for the case of small changes in design : (B) global approximation is exact for the case of large changes in a small number of design variables, but inefficient : (C) local-global approximation is most effective and reliable for the case of large changes with a large number of design variables. These methods can improve the total efficiency when they are appropriately used to the design information for the redesign process of large scale structures.

This study is based on Art Infusion type (modification vs. re-interprete and interactivity level (high vs. low) are independent variables such as 'Product-Related Memory (PRM)' and 'Image Related Memory (IRM)', Experimental research was carried out empirically through Two-Way MANOVA analysis with advertising attitude as a dependent variable. As a result, first, in the case of the modified advertisement, when the interactivity is low, the advertisement image-related memory information (IRM) is more memorized and affects the judgment. Second, in the case of reinterpreted advertising, the memory information related to product attributes is stored at low level regardless of the level of interactivity. Third, the attitude toward advertising for famous paintings was positive when the level of interactivity was low.

The aim of this study is to reinterpret the image on a Korean tradition known as Bang-wee-shin-sang (an image of direction deity), and to revive the image into Jikimee (the guardian). In particular, this research re-analyzed the image and the symbol of Bang-wee-shin-sang and effectively designed the tradition to fit the modern living space. The theoretical study is to explore why it is necessary to redesign Bang-wee-shin-sang to accommodate modern living after examining the background and origin of typical Korean traditions such as Four Deity painting, Chinese Zodiac, and Four Kings' Painting. As a previous study, we examined the procedures of making Jikimee which was based on artists' works that utilized historical artifacts. The study indicated that Bang-wee-shin-sang is a vital resource to disseminate the unique characteristics of Korea and its tradition which played a role in linking the past and the present. Consequently, it is discussed that the utilization of modernized Jikimee in smart environment must be supported by foundation of academic system, the effort of academic and research link, and government funding policy.

This study aimed to compare the effects of two emotion regulation strategies, namely, cognitive reappraisal and expressive suppression in female college students. Specifically, the effects of these two emotion regulation strategies were tested and the intrapersonal factors related to the effects of these strategies were explored. The participants included 60 female college students. In Study 1, 40 participants were randomly assigned to each of the two different strategy groups, i.e., a between-subject design was employed. In Study 2, 20 participants were asked to use both strategies to regulate their emotion, i.e., a within-subject design was employed. The results revealed that both emotion regulation strategies effectively reduced negative emotion of emotional stimuli. However, the use of emotion regulation assessed with a questionnaire was not matched to the actual usage of regulation strategies examined with a task. Finally, the use of a suppression strategy was related to the extroversion psychological adaptive variable. Our findings suggest that the subjective assessment of the use of an emotion regulation strategy may not be the same as the actual use of an emotion regulation strategy. Furthermore, we demonstrated that when participants have an option to use both strategies, the cognitive reappraisal is more functional than expression suppression. This concurs with the previous findings on the effects of emotion regulation strategies.

강상판교는 부재수가 많고 구조적 거동이 복잡하여 재래적인 단일수준 (CSL) 알고리즘을 이용하여 최적화하는 것이 매우 어렵기 때문에 본 연구에서는 강상판교를 효율적으로 최적화하기 위해 다단계 최적설계 (MLDS) 알고리즘이 제안되었다. 강상판교를 주형과 강상판으로 나누기 위해 등위법이 사용되었고, 시스템 최적화를 위하여 설계 변수를 줄이는 분해법이 사용되었다. 효율적인 최적설계를 위해 다단계 최적설계 알고리즘은 제약조건 소거기법(Constraint Deletion)과 응력 재해석 같은 근사화 기법을 도입하였다. 변위해석을 위한 제약조건 소거기법은 교량의 최적화에 효율적인 것으로 검증되었고, 제안된 응력 재해석 기법 또한 설계민감도 해석을 필요로 하지 않으므로 매우 효율적이다. MLDS 알고리즘의 적용성과 강건성은 다양한 수치예제를 사용하여 기존의 단일수준 알고리즘과 비교하였다.

본 연구는 국내가구 디자인 산업의 경쟁력 강화를 위한 사례의 하나로 디자인 작품을 시도하게 되었다. 지존의 디자인 모델링은 소프트 모델 또는 목업(mock up)개념에서 시행되어 디자이너가 직접 제작하기 전에는 3차원의 형상을 구현하기가 어려웠으며, 더욱이 문야의 적용은 실크스크린 또는 인쇄와 같은 처리기법으로 사용되었다. 이 방법은 시간, 경비, 공간, 자료의 보관 및 축적, 기타의 많은 문제점과 생산성 향상에 애로사항이 되어왔다. 요지와 같이 많은 문제점과 렌더링의 데이터베이스 뱅크는 활용 가능한 분야와 직종에 따라서 응용 가능하기 때문에 많은 실험적 시도가 요구된다. 디자인의 발상은 우리나라 전통문화의 가구디자인을 접목시킨 사례로서 시도하였으며, 형태와 문양을 현대적 개념에서 재해석하여 대입시켰다. 적용디자인 사례는 2개의 모델에 10가지의 패턴을 복합적으로 활용한 디자인 작품의 결과물이다. 이러한 결과는 다양한 디자인 연출과 시안을 추출할 수 있으며, 디자인 활동과 설계에 능률을 배가시키는 효과를 검증할 수 있겠다.
