  • The purpose of this study is to propose new hysteretic characteristics of medium- to low-rise RC structures controlled by both shear and flexure. Through previous study, the dual lateral force-resisting system composed of shear and flexural failure members has a new failure mechanism that cooperates to enhance the flexural capacity of the flexural failure member even after the failure of the shear member, and the existing theoretical equation significantly underestimates the ultimate strength. In this study, the residual lateral strength mechanism of the dual lateral force-resisting system was analyzed, and, as a result, an equation for estimating the residual flexural strength of each shear-failure member was proposed. The residual flexural strength of each shear-failure member was verified in comparison with the structural testing results obtained in previous study, and the proposed residual flexural strength equation for shear-failure members was tested for reliability using FEA, and its applicable range was also determined. In addition, restoring-force characteristics for evaluating the seismic performance of the dual lateral force-resisting system (nonlinear dynamic analysis), reflecting the proposed residual flexural strength equation, were proposed. Finally, the validity of the restoring-force characteristics of RC buildings equipped with the dual lateral force-resisting system proposed in the present study was verified by performing pseudo-dynamic testing and nonlinear dynamic analysis based on the proposed restoring-force characteristics. Based on this comparative analysis, the applicability of the proposed restoring-force characteristics was verified.

  • This paper aims to analyze the process of the evolution of Gumi electronics industrial cluster and to understand the role of governments for local industrial dynamics. Gumi was a typical satellite platform type new industrial district up to mid-1990s. At that time, Gumi industrial park was the agglomeration of branch plants headquartered in Capital Region with weak local linkages. During the last two decades, however, Gumi has evolved to an electronics industrial cluster with considerable local interfirm linkages and innovation activities of SMEs. Recognizing government industrial policies is critical in understanding the process of the evolution of Gumi electronics cluster. At the early stage, the state was the developer and locator of business activities within the confines of the Gumi industrial park. In recent years, central government's innovative cluster policy contributed to strengthening networks among firms, universities, and research centers to form local innovation networks as well as networks between large branch plants and SMEs. Gumi city and Gyungsangbuk-do promoted innovative activities of SMEs through the supports of cooperative networks between universities and SMEs. The increasing roles of SMEs and local governments in addition to the large branch plants and the central government have become the basis of the evolution of industrial cluster in Gumi.

  • Intelligent Transportation Systems (ITS) are advanced applications which, without embodying intelligence as such, aim to provide innovative services relating to different modes of transport and traffic management and enable various users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks. However, ITS has the different size and shapes according to the city environment policy to adjust the city scene and it has to be displayed by different message on the information display device in real-time. And the information service providers must make the information display system which has the different information and data each time. That is very time and workers consuming and auto message frame generation system is necessary. In this paper, we design and develop the message frame generation system which can set several parameters easily for the generation of the message frame automatically on the windows environment and we do not need to go the field to get the test data.

  • Today seafoods, such as fisheries and clams, have become an important part of our diet. But processing and storing these perishable seafoods for a long period of time present a serious problem. Only a few years ago, the seafood consumption was minimal. However, an improvement in our diet has enabled us to enjoy seafoods more often than before. Moreover, the recent trend toward the concentration of the popuration to the metropolitan area and the improvement in the standards of living have accelerated a change in our food consumption pattern-preference for the convenient foods over time consuming cooking. Judging from these changes, we can easily predict that the demand for the covenient, dried seafoods will rise sharply in the coming days. The development for an innovative and attractive way to package and market these products are on the way. Research and development of the distribution channel and package design of the dried seafoods will offer a wide array of opportunities to increase the sales volume of the dried seafoods. In addition, by associating the image of Pusan, as a prime oceanic city, with the dried seafoods on the package will certainly draw the attention of many prospective consumers. Consequently it will make the dried seafoods special products of Pusan, and eventually contribute to the prosperity of the city.

  • The Seoul subway system has one of the highest transport shares in the city of Seoul. A high number of passengers means that a high level of crimes of all kinds occur on the city's subway system. As such, Seoul Metro, created the Subway Protective Guards System in 2009, in an effort to enhance safety on the subway. But this innovative new system did not resolve problems. In fact, many citizens came to question the effectiveness of the new system, as it did not yield tangible results. This study seeks to deduce the problems and activation strategy of the Subway Protective Guards System. An in-depth study was conducted by interviewing subway protective guards who were squad leaders with five or more years of relevant work experience. Semi-structured interview analysis was utilized to evaluate their responses. Specifically, their responses were deduced to identify the strengths and weaknesses internal to the system and the opportunities and threats posed by the environment external to the system. This study presents measures to improve the system based on the aforementioned analysis. Measures for improvement focused on the following areas: the adoption of an education system in response to terror; recruitment and the possibility of becoming a permanent employee; obtaining partial judicial powers; improvement of work environment; and intensifying the promotion of the system.

  • A number of previous studies have maintained that information technologies, due to their ability to overcome distance, can nurturing an innovative class of polycentric urban configurations, i.e., network cities. The present study intends to clarify whether any network relationship has recently been emerged among Korean cities by the advancement of information technology. The analyses focused on the geography of Korean national domains (.kr domains), and the hyperlink associations among three major types of domains, namely commercial, academic, and organizational domains. The study findings altogether indicate that the advancement of global economy and information era appears to be enhancing, rather than reducing the status of primate city. Seoul dominates the entire nation, forming an enclave in the production and consumption of information. Only the domains of educational institutes show network-like relations among local centers to a certain extent. The paper concludes with a discussion on the implications of the findings for future research and ‘spatial’ policy measures.

  • The purpose of this study is to understand the characteristics of books selected for 'The Big Read' community reading initiative of the National Endowment for the Arts from 2006 to 2017 and its relation with 'One Book, One City' community reading campaign in the U.S.A. An analysis of 1,407 TBR programs and 745 participating communities, and 56 books from TBR Library shows that TBR expands and complements 'One Book' reading campaigns, and confirms the sustenance of this innovative model. TBR Libray books were selected with TBR's own criteria, but their features are generally very similar to those of 1,102 books selected for 'One Book' programs. They often reflect some interests in such universal values as coming of age, justice, integrity, etc. and diverse cultural experiences and life. The outcomes of 'One Book' and TBR cannot be qualitatively measured, but their sustainable value of communication through one selected book has been well proved.

  • Objectives: This study aimed to analyze the status of dental care in underserved areas of Korea. Methods: This study targeted 229 cities in Korea. The analytical index was revised and supplemented with variables related to dental care, and the "oral health level" indexes were further selected to provide a total of 20 analytical indexes. All selected indexes were converted into T scores (cited by the Korea Health Promotion Institute) and subjectively weighted. Finally, the regional oral health indices and areas were derived. PASW Statistics 25.0 (SPSS Inc. Chicago, IL, USA) was used to analyze descriptive statistics. Results: Gyeongbuk Cheongsong-gun had the highest dental underserved index. The city with the highest regional oral health underserved index was Jeonnam Shinan-gun. Daegu Jung-gu had the lowest dental underserved index and regional oral health underserved index. Regional gaps existed between dental care and the regional oral health underserved index according to the city province (p<0.001). Conclusions: To continuously evaluate oral health conditions and projects centered on vulnerable areas, it is necessary to develop indicators to derive vulnerable areas for dental care and to develop effective public dental policies.

  • Smart tourism is seen as a revolution in the tourism industry, involving innovative and transformative theoretical-practical approaches for the sector. As a result of its application in the tourist context, benefits can be seen such as more sustainable practices, greater mobility and better accessibility in destinations, evolution of processes and experiences of tourists. Much of this is achieved through the support of technological solutions. However, despite the immense expectations, and the many researches carried out on it, a literature summary regarding the dimensions that can be observed in each application of this smart tourism has not yet been proposed. Therefore, supported by the PRISMA recommendation, this research proposed to carry out an integrative review of the literature on smart tourism (in its different levels of application, such as the city, the destination and the smart tourism region), with the objective of mapping the dimensions that underlie it. Thus, from an initial scope of 833 intellectual productions obtained, inputs were found for the dimensions in 363 of them after a thorough analysis. The compilation of data obtained from these productions supported the proposition of 14 operational dimensions of smart tourism, namely: collaboration, technology, sustainability, experience, accessibility, knowledge management, innovation management, human capital, marketing, customized services, transparency, safety, governance and mobility. With this set of dimensions, it is envisaged that the implementation of smart tourism projects can present more comprehensive and assertive results. In addition, shortcomings and opportunities for new research that support the evolution of the theory and practice of smart tourism are highlighted.
