The value of using health insurance claim database is continuously rising in healthcare research. In studies where comorbidities act as a confounder, comorbidity adjustment holds importance. Yet researchers are faced with a myriad of options without sufficient information on how to appropriately adjust comorbidity. The purpose of this study is to assist in selecting an appropriate index, look back period, and data range for comorbidity adjustment. No consensus has been formed regarding the appropriate index, look back period and data range in comorbidity adjustment. This study recommends the Charlson comorbidity index be selected when predicting the outcome such as mortality, and the Elixhauser's comorbidity measures be selected when analyzing the relations between various comorbidities and outcomes. A longer look back period and inclusion of all diagnoses of both inpatient and outpatient data led to increased prevalence of comorbidities, but contributed little to model performance. Limited data range, such as the inclusion of primary diagnoses only, may complement limitations of the health insurance claim database, but could miss important comorbidities. This study suggests that all diagnoses of both inpatients and outpatients data, excluding rule-out diagnosis, be observed for at least 1 year look back period prior to the index date. The comorbidity index, look back period, and data range must be considered for comorbidity adjustment. To provide better guidance to researchers, follow-up studies should be conducted using the three factors based on specific diseases and surgeries.

Many modern movies and animations rely heavily on CG (computer graphics). The use of CG has made it possible to produce beyond the limits of visual expression. There has also been an increase in technical and artistic efforts to create new and high quality CGs. Look development is the process of modifying and creating shaders and renderings in 3D to produce CGI (computer-generated imagery) that meets the director's intentions. However, small production or projects may have relatively little or no awareness of look development in the production pipeline. The problems that can occur when look development is not preceded are classified into three categories. first, the shader may react differently under the same lighting conditions. Second, there can be a problem in communication between workers. Third, there is a waste of not promising a look for a given situation. As a way to avoid these problems I studied by creating consistency by the look development system. In the limitation that make it difficult for small studios to do look development because of small workers, time and cost, it is meaningful to study and present a simple look development process that can be carried out by individual or small production.

Our study of rider's postulator stability and tracking control on a unicycle began form the observation of a human riding. The system including unicycle and human operationg his unicycle is a fuzzy intelligent biomechanical model on basis of instinct and intuition search mechanisms. We proposed a robotic unicycle with one wheel and one body as a basic mode and derived equation of motion to this model. Our works is in making out fuzzy look-up table to control robotic unicycle. Fuzzy look-up table were determined for staight line and curve under reasonable inference emulating human's instinct and intuition riding a unicyale. Simulation results show that postulator stability and tracking control on both straight line and curve were successful by using proposed each fuzzy look-up table.

This research aims to analyze the prep-hop fashion, which is an original look created through the convergence of the hip-hop and preppy look, and identify the design characteristics of the prep-hop fashion. The style mixes the fashion of what was traditionally a lower-class look with the upper class. The design characteristics are as follows: First, the prep-hop fashion expresses slim, casual and sophisticated look with items and silhouettes. The items are categorized into jackets, shirts and pants. The prep-hop jackets provides a casual look to its wearer unlike the jackets of preppy or conservative looks. Slim suits show different meanings and features depending on the changes in the time and culture despite the continued use of the items. Second, the colors of the prep-hop fashion include overall basic colors used in the preppy look and hip-hop fashion. The aesthetic values of the colors express pleasant color images different from the conservative and resistant images expressed in the preppy and hip-hop style before the convergence, respectively. Third, the materials and patterns are expressed in a unique way to fulfill the emotional needs that are considered vital to contemporary fashion. The materials in the prep-hop fashion extend the ranges of usage by using the materials with unexpectedness broken out of general range of usage. While the use of the patterns is one of the methods to demonstrate that the prep-hop fashion is created by the convergence between hip-hop fashion and preppy look, the meaning concludes pleasantness and casualness different from the past. Fourth, the prep-hop fashion is mainly composed of hip-hop fashion accessories, which express the authenticity of the hip-hop fashion to protect the non-mainstream characteristics. The design characteristics of the prep-hop fashion pursue the individuality of the contemporary fashion, which lacks originality due to commercialization. The development of the prep-hop fashion, as a new form that combined contrasting genres and trends, is expected to develop more publicly.

Then, the formative expression was examined about those looks and the characteristics were induced from them. Formativeness expressed in Galliano's lingerie look, in term of lingerie style, was categorized as erotic, retro, and deconstructive. The glittering and smooth material like silk and satin, and the visible material like lace and chiffon were mainly used for material rather than foreign material. By doing so, the romantic and erotic image was highlighted. In the production method, it was grouped into transposition of wear, direct and indirect exposition, and deconstructive way. These aesthetic characteristics introduced by formative expression appeared in the form of eroticism, play, and deconstructiveness.

This study intended to analyze the grunge look as a mode of expression and as a characteristic of the fashion of the 21st century, arguing that the look expressed not only an outward appearance or sub-culture but also a change in our attitude and spirit about contemporary fashion. In the study, I carried out an empirical analysis focused on the collection from 2001S/S to 2010F/W and a literature review. In my results, I classified the grunge look into the following categories: 1. mix and match layering; 2. patchwork, collages, and assemblage using all objects as well as clothing materials; and 3. distressing techniques, such as bleaching and dyeing, unweaving, and tears and holes. I also classified the characteristics of grunge into the following categories: 1. conspicuous destitution, which is intentionally expressed by skillful techniques and craftsmanship, indicating that modern people want to attract attention and be distinguished from others, which reflects an attitude of superiority through ironic fashion choices; 2. high lighting the dissolution of decoration, where destruction, poverty and recombination shown in the grunge look emerged as an artificial and intentional ugly aesthetic in contrast to the existing elegant and sophisticated image; and 3. satire and playfulness, as grunge expresses alienation and conflict in modern society through satire and sarcasm, not attacking or avoiding, but through playful and sarcastic engagement so as to decrease poverty and give temporary freedom.
