The purpose of this study was to examine the characteristics of change in the composition of indoor spaces in Korean-style houses which have been repaired and improved extensively through the 'Bukchon Improvement Project' and are being utilized for public purposes. For this, we conducted a field survey through visiting the house sites from the 5th to the 26th of May, 2006. Conclusions drawn from this study are as follows. Bukchon Korean-style houses maintain centripetal space composition, in which the rooms surround the court. Centering on the court, the hierarchy of spaces is determined, and the hierarchy of spaces and the composition of internal layout are restructured centering on the court and the main hall without change in direction and position. The main hall is sometimes converted to a room, but it maintains an open space relation with other spaces centering on the court, and therefore, even after its use has been changed, it is still the most Korean-style space. In addition, with floor heating, the common sitting-style life is maintained continuously although the rooms have been converted and standing-style furniture is used. In this way, publicly promoted policies for Korean-style houses are allowed within the limit that the appearance is maintained and the internal spaces do not change the overall structure. However, in order to maintain the tradition of Korean-style houses and utilize them as various spaces, the following supplementations are necessary. First, the main hall and the inner court of a Koreanstyle house should be utilized actively. The court sometimes keeps individuals' privacy or expands the space by extending the view to outdoor spaces, and is sometimes used as an open space through interconnection between the inside and the outside of the house. Second, consideration should be given to vertical spaces. Horizontal expansion causes a change of floor plan. Thus, space should be secured using various cross-sectional changes, such as a kitchen and a loft over the kitchen. Third, structure should be changeable in order to adjust the size of spaces. Thus, through research on traditional windows, we need to develop changeable walls that can be installed and removed easily according to the use of spaces.

The usual practice of placing viscoelastic dampers (VED) in the inter-story of building structures frequently interfere with spatial planning and obstruct internal view. These shortcomings can be overcome by installing VED in seismic joints or in expansion joints which are usually hidden under a cover. This study investigates the effect of installing VED in seismic joints to reduce earthquake-induced dynamic reponses. Parametric studies were conducted using 3-DOF systems connected by VED and subjected to earthquake excitations to investigate the effectiveness of the proposed scheme. Nonlinear dynamic analyses were carried out with five-story structures composed of different structure systems and connected by seismic joints. According to the analysis results the use of VED in seismic joints turned out to be effective as long as the natural frequencies of the connected structures are different enough.

Modern society shares new culture derived from the fusion of various cultures unlike the past culture regulating one phenomenon of certain field as the representative icon of the era. Especially, the phenomenon of globalization acts as the catalytic agent to receive coexistence of variousness easily. Especially, in fashion industry, these flows and the view of naturalism are harmonized and new fashion trend called 'Ethnic' was embossed. As it reflects internal spirit of human being that wants to return to the memory due to expansion of material civilization, the interest in the designer pursuing it is increasing. This study tries to consider the Ethnic style displayed by Chinese American designer, Anna Sui, who pursues the eastern style with full wit and individuality. Anna Sui, who was praised by New York Times for 'the superb harmony of houte couture style and up-to-date style', created another fashion trend, romanticism in New York and she is the worldwide designer representing Ethnic. Like it, the consideration on her Ethnic style reanalyzing as eastern style provides guidance to check how designer's fashion philosophy appears in one category of America and China and new study material that enables us to understand the third world culture code as well as Anna Sui. This confirmation has the meaning as the basic material for the endless challenge to the new style that fashion will go on in the future. Anna Sui was confirmed to have been recognized as a designer who represented the ethnic collection in the United States, exerting the influence with her unique oriental background. Moreover, her design could identify the pivotal point of ethnic image by developing her unique style which is distinct from other designers in terms of silhouette, color, fabric, detail, and so on. This kind of study can provide the basic data required to understand the fashion world of designer in the future.

The internal pressure is a critical parameter for designing a pressure vessel. The static pressure that a pressure vessel must withstand is usually determined according to the various codes and standards with simple formula or numerical simulations considering the geometric parameters such as diameter and thickness of a vessel. However, there is no specific codes or technical standards we can use practically for designing of pressure vessels which have to endure the detonation pressure. Detonation pressure is a kind of dynamic pressure which causes an impulsive pressure on the vessel wall in a extremely short time duration. In addition, it is known that the magnitude of reflected pressure at the vessel wall due to the explosion can be over twice the incident pressure. Therefore, if we only consider the reflected pressure, the design of the pressure vessel can be too conservative from the economical point of view. In this study, we suggest a practical method to evaluate the magnitude of maximum allowable pressure that the pressure vessel can withstand against the detonation inside a vessel. As an example to validate the proposed method, we consider the pressure vessel containing hydrogen gas.

This paper is a study on city brand development which is increasingly interested as a means to enhance the attractiveness of the city. the previous research, the design of city brand identity was an application from the internal stakeholder's point of view related to the metropolitan government. However, in the present study, we tried to take a external approach that perceptions and designs city brands from the related to the consumer. For the purpose of research, based on previous studies, we extracted three images of leading, stable and amusing city brand images and prepared three scenarios for the imaginary city as experimental stimuli. The results showed that the overall city brand attitude, residence intention, and tourism intention to the imaginary city were significantly different according to the leading, stability and amusement brand image. According to the results of this study, it is necessary to continuously effort the development of city brand image which is perceived by consumers in order to differentiate city.

Purpose - We attempted to empirically verify the effects of managerial attributes on cost stickiness in exporters. Exporters are often affected not only by external factors such as exchange rate but also by internal factors such as managerial attributes regarding their business activities. Because cost stickiness is the product of a manager's decision-making, it has been considered that managerial attributes have a great influence on the behavior. Therefore, our study was intended to find out whether cost stickiness shows differentiated aspects depending on managerial attributes in exporters. Design/methodology - We considered two managerial attributes: CEO power and managerial overconfidence. First, CEO power was measured as CEO pay slice. In addition, managerial overconfidence was measured based on three methodologies presented by previous studies. To measure cost stickiness, we used multiple methodologies presented by prior research. Findings - The results of our empirical analysis are as follows. First, in export firms, the greater CEO power is, the greater cost stickiness is. This result suggested that export managers with great influence little respond to temporary sales decrease promptly, little reduce related production costs flexibly in preparation for future sales recovery, but leave room to endure costs for idle resources. Second, the greater managerial overconfidence is, the greater cost stickiness is. This result indicated that export managers with great overconfidence on their decision-making often view the prospect for sales recovery positively; therefore, they little respond to temporary sales decrease immediately, little reduce related production costs flexibly for future sales recovery, but leave room to endure costs for idle resources. Third, export managers with great influence in their businesses and great overconfidence in their decision-making tend to show relatively great cost stickiness. The results proposed that the combination of the two factors functions to make cost stickiness greater. Originality/value - Our study is differentiated from extant studies in that we provided empirical evidence of the effects of managerial attributes on their business activities in exporters. Specifically, we verified the effects of managerial attributes on cost stickiness in Korean exporters. The results of our study are expected to contribute to providing useful information for exporters and start-ups.

Purpose - Recently, as the franchise market has grown rapidly and competition has intensified, the creation of competitive advantage by companies has become important as a corporate survival strategy. Based on previous studies, this study proposed a theoretical framework for the structural relationship between psychological ownership (organization and job), job performance, and customer orientation. Research design, data, and methodology - This research examines the structural relationship between psychological ownership, job performance, and customer orientation in terms of employees. More specifically, in this model, psychological ownership consists of two sub-dimensions of organization and function. Research models and hypotheses have been developed for this purpose. A total of 409 respondents responded via surveys. 2 out of 409 respondents have been removed and a total of 407 were used for this study. The data were analyzed using frequency analysis, confirmatory factor analysis, correlation analysis, and structural equation modeling with SPSS 21.0 and Amos 21.0 statistical program. Result - The results of the study are as follows. First, psychological ownership (organization and job) has a statistically significant positive effect on job performance. Second, psychological ownership of the job has a statistically significant positive effect on customer orientation. On the other hand, psychological ownership did not have a significant effect on customer orientation. Conclusions - The implications of this study are following as: From the theoretical point of view, this study distinguishes the psychological ownership of employees of a franchise corporate into two dimensions, organization and job, rather than a single dimension. Based on this, we examined the effect of psychological proprieties on job performance and customer orientation. This study also provides several implications. In a fiercely competitive franchise market, it is very important to analyze your employees to gain a competitive advantage over other competitors. It is meaningful to study the employees who work in the franchise. In addition, psychological ownership is an important variable that enhances job performance and leads to customer orientation, so the company needs to pay attention. Therefore, it needs to develop an internal marketing strategy that promotes psychological ownership.
