In the past 20 years, seismic isolation has see a variety of applications in design of structures to mitigate seismic hazard. In particular, isolation has been seen as a means of achieving enhanced seismic performance objectives, such as those for hospitals, critical emergency response facilities, mass electronic data storage centers, and similar buildings whose functionality following a major seismic event is either critical to the public welfare or the financial solvency of an organization. While achieving these enhanced performance objectives is a natural (and oftentimes requisite) application of seismic isolation, little attention has been given to the extension of current design practice to isolated buildings which may have more conventional performance objectives. The development of a rational design methodology for isolated buildings requires thorough investigation of the behavior of isolated structures subjected to seismic input of various recurrence intervals, and which are designed to remain elastic only under frequent events. This paper summarizes these investigations, and proposed a consistent probabilistic framework within which any combination of performance objectives may be met. Analytical simulations are presented, the results are summarized. The intent of this work is to allow a building owner to make informed decisions regarding tradeoffs between superstructure performance (drifts, accelerations) and isolation system performance. Within this framework, it is possible to realize the benefits of designing isolated buildings for which the design criteria allows consideration of multiple performance goals.

Since ancient times in Korea, in spite of the ranks of high and low, drink was like a all sorts of human emotions. In particular, the drought, or any weapon except when wages found the ball back to God or to buy a drink to celebrate the sixtieth birthday or marriage and feasting like mails, and the priests or the funeral, such as consciousness raising in this procedure. The country had strict rituals in ceremonial events were thereby is living up to deep. The history of the drink in the history of the past, given that the main grain farming culture has already begun since the era of gojoseon was launched remains to be seen. This has been a long history of traditional attention to clean up and organize the showing to the public hall is a nationally scarce in some areas of that era, or the facility is not large. Therefore, in this study, alcohol-related exhibits and Museum recognizes the reality of the future sake Museum architectural plans: the Foundation provides materials for that purpose.

Modular construction is attracting attention as the solution of recent problems in construction site. Such as lack of construction workforce, increasing labor costs, work delay due to extreme weather events and strengthening government regulations. However, despite the many advantages, Modular construction has not been activated dueto high construction costs compared to other construction methods. Accordingly, the object of this study is priority derivation of prefabricated house cost reduction factors and use as basic research data. For research performance, we have analyzed the blueprint and bill of quantities of a modular construction based public dormitory which was built in 2013. In result, the proportion of modular construction and on-site construction is 66% and 34%, and the construction cost proportion by activity was devided in to construction(79%), machinery(7%), electricity(5%) and civil(9%). Among these results in order to reduce costs, interior finishing(19.4) steel-frame(16.9%), metal works(13.5%), RC(11.8%), joinery(7.3%) is the order requires focused management.

This study is intended to examine the effect of characteristics of museum visitors and visit type on perceived relative status, aesthetic responses, and perceived visit benefits, which in turn affect visitor satisfaction and personal and social participatory behaviors. Research was held for four weeks. A total of 308 questionnaires were collected out of 315 distributed. However, additional 15 were excluded due to inadequate responses. The findings of the study are as follows: While museum visitor characteristics yielded significant effects on the perceived relative status and perceived visit benefit, it did not have significant effects on aesthetic responses. Additionally, while visit types showed considerable impact on perceived relative status, it did not yield significant effect on aesthetic responses or the perceived visit benefit. Perceived relative status of a museum had positive effects on aesthetic responses, but not on the perceived visit benefit. Furthermore, while perceived relative status did not have significant effect on visitor satisfaction, it did have evident effects on the aesthetic response and the perceived visit benefit. Lastly, greater visitor satisfaction was confirmed to contribute to greater participatory behavior in various prospective programs and events offered by museums. Hence, it would be imperative for museums to gear their attention to encourage internal participatory behaviors such as visitor education, donation and charity events, which would consequently transcend to viewing museums more as a public space shared by the general public.

This study selected a case study method conforming to qualitative research in order to analyzed how each type of fashion enterprises uses SNS in-side of fashion marketing based on content the researcher monitored and selected from the Facebook website for each enterprise. The standard to select fashion brands in this study is a graded list made based on ranking 5 analysis sites on social media (Socialbakers, socialDigm, Pulse K, BigFoot9, L2). The researcher sorted and then analyzed 2 brands that have many fan joiners and followers among fashion brands that were ranked top of the graded list, work in Facebook animatedly, and had representativeness in each type (SPA, Sports Brands). The study was conducted from January 2013 to March 2013, and the index of Facebook consisted of 3 kinds of elements (comment, like, and share). Each numerical value was counted to decide the monthly ranking. Content analysis was divided into public relations about brand, public relations about products, and customer participation and activities; consequently, the researcher investigated which content was post conforming to the ranking. The study analyzed the analysis results of each brand derived through the method of study compared to other brands. The results are as follows. In case of SPA brands, the category accounting for high rank in index analysis are public relation events to attract customer attention and products and offering information. The results of the monthly trend about whole post category were also similarly analyzed so the promotion goal that the brand wants to seek in priority coincides with the customer compliance rate. Next, in the case of sports brand, public relations for products offering information, event for arousing customer concern, and participation activities accounted for a high rank in the index analysis and posted the most in the analysis of the monthly trend for whole post category. The researcher came to understand that the direction of content for brands shown through Facebook coincides with customer sympathy.

Phytochemicals are among the natural chemopreventive agents with most potential for delaying, blocking or reversing the initiation and promotional events of carcinogenesis. They therefore offer cancer treatment strategies to reduce cancer related death. One such promising chemopreventive agent which has attracted considerable attention is sulforaphane (SFN), which exhibits anti-cancer, anti-diabetic, and anti-microbial properties. The present study was undertaken to assess effect of SFN alone and in combination with a chemotherapeutic agent, gemcitabine, on the proliferative potential of MCF-7 cells by cell viability assay and authenticated the results by nuclear morphological examination. Further we analyzed the modulation of expression of Bcl-2 and COX-2 on treatment of these cells with SFN by RT-PCR. SFN showed cytotoxic effects on MCF-7 cells in a dose- and time-dependent manner via an apoptotic mode of cell death. In addition, a combinational treatment of SFN and gemcitabine on MCF-7 cells resulted in growth inhibition in a synergistic manner with a combination index (CI)<1. Notably, SFN was found to significantly downregulate the expression of Bcl-2, an anti-apoptotic gene, and COX-2, a gene involved in inflammation, in a time-dependent manner. These results indicate that SFN induces apoptosis and anti-inflammatory effects on MCF-7 cells via downregulation of Bcl-2 and COX-2 respectively. The combination of SFN and gemcitabine may potentiate the efficacy of gemcitabine and minimize the toxicity to normal cells. Taken together, SFN may be a potent anti-cancer agent for breast cancer treatment.

Investor mood from social media is gaining increasing attention for leading a price movement in stock market. Based on the behavioral finance theory, this study argues that sentiment extracted from social media using big data technique can predict a real-time (short-run) price momentum in Chinese stock market. Collecting Sina Weibo posts that related to COVID-19 using keyword method, a daily influential weighted sentiment factors is extracted from the sizable raw data of over 2 millions of posts. We examine one supervised and 4 unsupervised sentiment analysis model, and use the best performed word-frequency and BiLSTM mdoel. The test result shows a similar movement between stock price change and sentiment factor. It indicates that public mood extracted from social media can in some extent represent the investors' sentiment and make a difference in stock market fluctuation when people are concentrating on a special events that can cause effect on the stock market.

The purpose of this study is to review educational value of cultural heritage sites first and then, to examine the importance of interpretation and interpretation methods and process briefly to utilize cultural heritage sites as important resources for public education and cultural tourism. The educational value of cultural heritage sites is not limited to provide visitors with various information on historical facts and events related to the cultural heritage site, but to provide the public with a new recognition of the importance of the preservation of cultural heritage sites by understanding the site well. In order to utilize the educational value of the cultural heritage site, interpretation must be emphasized as an important element of cultural heritage sites management and much attention should be given on the development and practice of interpretation programs in each cultural heritage site. In order to develop an interpretation program of the site, a specific target audience must be defined first to find most resonable scope and direction of an interpretation program and then, site specific interpretation themes (or a theme) should be developed from the interpretive topic. According to these defined elements, an interpretation program(s) is established by using various interpretation methods and techniques in order to provide visitors with useful information and knowledge on the site efficiently. Interpretation methods and techniques are various as defined by various ways and most effective methods or techniques are employed as a specific interpretation program is presented most effectively. The evaluation processes in planing stage, during developing stage, and after completion of interpretation program development are important processes to find out any problems of planed interpretation program and to revise or update the interpretation program. Conclusively, the direction of cultural heritage sites management in Korea has focused on the conservation and restoration of cultural heritage sites to preserve the original conditions of cultural heritage sites so far. This direction on current practice on cultural heritage sites management should he changed to more active utilization of the sites and interpretation of the sites is a way to accomplish the this goal.

Under the pressure of the selection of topics and the presentation rules of mass media, politics in media society increasingly resort to professionalized forms of theatrical staging as a means of self-portrayal. Although these staging methods are not contradictory to what is actually going on in politics, they strongly advantage the tendency to focus exclusively on the staging of an event. Through their competition for public attention, politicians have been developing sophistication regarding placement and staging of events as well as regarding factual information. In the process of this transformation, politics that are issue-related and based on binding decisions are being gradually transformed into symbolic politics. Moreover, through their appearance on TV, politicians first of all need to possess presentational skills which are not necessarily related to their political achievements. Still, presentational skills decide over the success in politics of those politicians. The reason is that a politician who possesses presentational skills is still being perceived as being successful even if his political achievements notedly lag behind. On the other hand, political achievements are being underrated if a politician lacks the talent to present himself in front of the media. “The staging of politics, “politainment”, on the stage of mass media is evolving into a key structure which is responsible for a new coinage of politics in all different kinds of dimensions: the selection of staff, the role of action programs and their impact for the legitimation of political acting, even in relation to therole of pivotal political institutions such as parties and parliaments in the political process. The TV debates during the Bundestag elections of the year 2002 and 2005 are being analyzed and judged as “staging of politics”(politainment). Self-dramatization in media society concerning media discourses about politics and political self-portrayal has become a basic principle of political communication. Self-dramatization is a vital challenge for adequate political communication and content-based orientation in our present media democracies.
