The design of reinforced concrete structures strongly depends on the value of the compression concrete strength used for the structural components. Given the uncertainties involved on the materials quality provided by concrete manufacturers, in the construction stage, these components may be either over or under-reinforced respect to the nominal condition. If the structure is under reinforced, and the deficit on safety level is not as large to require the structure demolition, someone should assume the consequences, and pay for the under standard condition by means of a penalty. If the structure is over reinforced, and other failure modes are not induced, the builder may receive a bonus, as a consequence of the higher, although unrequested, building resistance. The change on the building safety level is even more critical when the structure is under a seismic environment. In this research, a reliability-based criteria, including the consideration of expected losses, is proposed for bonification/penalization, when there are moderated differences between the supplied and specified reinforced concrete strength for the buildings. The formulation is applied to two hypothetical, with regular structural type, 3 and 10 levels reinforced concrete buildings, located on the soft soil zone of Mexico City. They were designed under the current Mexican code regulations, and their responses for typical spectral pseudoaccelerations, combined with their respective occurrence probabilities, are used to calculate the building failure probability. The results are aimed at providing objective basis to start a negotiation towards a satisfactory agreement between the involved parts. The main contribution resides on the explicit consideration of potential losses, including the building and contents losses and the business interruption due to the reconstruction period.

The Iksan Mireuksaji stone pagoda, designated as national treasure No. 11 in Korea, has been in the process of disassembling for reconstruction as part of the cultural heritage conservation program. The pagoda is mainly consisting of granite, which is relatively resistant to weathering. However, it has lost its original rock color due to various contaminants deposited at the surface since it exposed to the atmospheric environment long time. In this research, we categorized the secondary inorganic contaminants into the genetic type, and also quantitatively examined occurrences and types of pollutants in the oxidation area of the pagoda surface in which the area is clearly distinguished by naked eyes. Geochemical behavior of soluble pollutants through reaction experiments are demonstrated, and effective methods of cleaning for the conservation and scientific applicability of the surface cleaner are also studied.

To understand day-to-day fluctuations in soil moisture content in Seoul, I simulated daily soil moisture content from 1908 to 2009 using long-term climatic precipitation and temperature data collected at the Surface Synoptic Meteorological Station in Seoul for the last 98 years with a hydrological simulation model, BROOK. The output data set from the BROOK model allowed me to examine day-to-day fluctuations and the severity and duration of droughts in the Seoul area. Although the soil moisture content is highly dependent on the occurrence of precipitation, the pattern of changes in daily soil moisture content was clearly quite different from that of precipitation. Generally, there were several phases in the dynamics of daily soil moisture content. The period from mid-May to late June can be categorized as the initial period of decreasing soil moisture content. With the initiation of the monsoon season in late June, soil moisture content sharply increases until mid-July. From the termination of the rainy season in mid-July, daily soil moisture content decreases again. Highly stochastic events of typhoons from late June to October bring large amount of rain to the Korean peninsula, culminating in late August, and increase the soil moisture content again from late August to early September. From early September until early October, another sharp decrease in soil moisture content was observed. The period from early October to mid-May of the next year can be categorized as a recharging period when soil moisture content shows an increasing trend. It is interesting to note that no statistically significant increase in mean annual soil moisture content in Seoul, Korea was observed over the last 98 years. By simulating daily soil moisture content, I was also able to reconstruct drought phenomena to understand the severity and duration of droughts in Seoul area. During the period from 1908 to 2009, droughts in the years 1913, 1979, 1939, and 2006 were categorized as 'severe' and those in 1988 and 1982 were categorized as 'extreme'. This information provides ecologists with further potential to interpret natural phenomenon, including tree growth and the decline of tree species in Korea.

Purpose - Competition among cities around the world are rapidly shifting from competition of production factors such as labor costs and quality of raw materials to competition between the consumption factors such as quality of life, settlement environment, culture, and place. The entry into the era of competition between consumption factors is not only attracting investment for strengthening city competitiveness, but also actively inducing urban image reconstruction and new image making. Therefore, various studies related to urban marketing are being carried out. The object of this study is to investigate the effect of city brand image on city brand recognition and city loyalty based on the questionnaire of external citizens about Changwon city. Research design, data, and methodology - The data were collected from 200 Seoul and Busan citizens. Reliability and exploratory factor analysis were conducted through the SPSS program, and confirmatory factor analysis and structural equation modeling were conducted by using the AMOS program. Results - As a result of the hypothesis test, six hypotheses were adopted among the nine hypotheses. In summary, pleasant image, dynamic image, and good administrative image have a significant positive impact on city brand recognition. The magnanimous image did not have a significant effect on city brand recognition. In the impact of city brand image on city loyalty, magnanimous image and good administrative image had significant positive impact on city loyalty. Pleasant images and dynamic images did not significantly affect city loyalty. In addition, city brand recognition positively influenced city loyalty. Conclusions - First, it is possible to say that there is an academic significance of this research in its contribution to regional revitalization by investigating mutual influences in urban aspect by combining place marketing with image, recognition, and loyalty. Secondly, kinetic images such as pleasant image and dynamic image have more influence on recognition, and static images such as magnanimous images have more influence on loyalty. So, further research will be necessary to establish theories. Finally, In order to increase city brand recognition and city loyalty to local city, efforts should be made to improve urban images such as pleasant image, magnanimous image, dynamic image, and good administrative image.

Even though the United States and Australia have a relatively short history, the preservation and reuse of their historical heritage and cultural heritage are considered to be very important. In the case of Korea, which has a long historical heritage, there is a lack of development and restoration systems and there are no clear guidelines on how to preserve and reuse these precious legacies. In this study, we examine and analyze through examples how the historic buildings have been preserved and reused in Australia and the United States, which have a shorter history than our own. Also, we suggest that the raising of awareness of the historicity associated with the existing architecture and that of the architectural environment following its full-scale reconstruction will enable them be considered historical heritages with the passing of time.

The purpose of this study was to investigate teachers' recognition on field practice and effectiveness of creativity and character education. This study used post tests to examine the effects of teacher training for creativity and character education on 451 teachers. The results were as follows. Firstly, the average in satisfaction of teacher training for creativity and character education was 4.65 for elementary teachers and 4.35 for secondary teachers in summer, and 4.55 for elementary teachers and 4.42 for secondary teachers in winter. Secondly, effectiveness of teacher training on creativity and character education was showed highly as more than 4.0 and was higher in winter than in summer. Thirdly, in the case of field practice and effectiveness of teacher training for creativity and character education, the average of elementary teachers(3,66) was higher in respect of educational environment than that of secondary teachers(3.20) and the averages of elementary teachers and secondary teachers were 3.85 and 3.42 in respect of subject activity, respectively. In practising creativity and character education, it was analyzed that both elementary(ave. 3.89) and secondary(ave. 3.84) teachers went through some difficulties for curriculum reconstruction, development of instructional model, program development, and human and physical supports.

Universities in Korea are exerting every effort to make great strides through restructuring at the moment. Reconstruction accompanied by readjusting the quota and merging of academic departments inevitably require rearrangement of resources and assets of those universities. This paper presents a management method with respect to the spaces held by a university based on the public concept of space through which a system has been implemented as an example. Such attempt makes it possible for the university to adequately cope with changes in its business environment through its effective management with regards to the available spaces on campus. Spaces are all the members' shared public assets. If there is a demand for a space, the university should be able to meet the demand. If the use of a space expires, the university should be able to retrieve and reallocate it. The space classification system presented in this paper may play a huge role in fixating space chargeback system.

This study investigates how learners extract their implicit knowledge into explicit form of the knowledge. The process of implicit-explicit transfer is known to help learners to reconstruct and refine their knowledge which was constructed before in some ways. Also we investigate which types of explicit form are more effective when it is delivered to other learners. In a classroom-based learning environment, students take educational content that is delivered by instructor and go through the process in which they try to fit the content into their cognitive structure by reconstructing the knowledge into their cognitive model. When they try to deliver their own cognitive model for the knowledge to other learners, they have to transform it into explicit form, and through the process, they reconstruct and refine the cognitive model of the knowledge, and find effective and appropriate way to express it. In this research, we experimented the process on a group of 77 college students and analyzed the results. We also did peer evaluated experiments to see which types of explicit format and factors are more effective than others. The results indicate that the types of explicit form of implicit knowledge play an important role in effectiveness of learning.

Considering Korean feminist theatre is not successful at all these days, it is needed to find the reasons of its crisis. As two Korean feminist theatre Scholars argued, the crisis owed to the structural problem from the start. That is the Korean feminist theatre started and developed depending on the imported popular feminist plays without social and cultural self-consciousness. Once the imported feminist theatres were flourished, some theatre companies pursued the commercial success blurring the feminist issues. It was resulted into the intentional ignorance in and out of the theatre society. While, some feminist plays were too inclined to the agit-prop without artistic sophistication. This essay tries to examine how the feminist theatres have been developing and what kinds of feminist performances have been made until now. And it intends to emphasize that the play text should be based on the Korean women's past, present, and future reality. Besides, they have to delve into the problem by which the Korean women were trapped in historical, social, and cultural environment. To make the women's matter the social issue at present and fur the future, the Korean feminist theatre should re-find its place as the socio-cultural forum. First, Korean theatre should cooperate with the other women's group crossing the different disciplines of the society, the culture, the politics etc . Secondly, we need to observe and watch where and how the distortion happens in women's matter, and react to correct it. Thirdly, we need to discover, to support, and to protect the women centered perspective of some playwrights as well as the performers. Co-writing or co-performing is also very positive to diversify the women's subjects. Lastly, to protect the feminist theatre against the consumerism, they need to have the financial support from the government or some civil society.

In this paper, we propose a system to detect spatial structures in land cover maps and to detect time-series spatial structure changes. At first, the proposed system detects patches in a certain area at different times and calculates their measures to analyse spatial structure patterns of the area. Then the system conducts patch mapping among the detected time-series patches and decides 6 types of patch changes such as keeping, creating, disappearing, splitting, merging, and changing in a mixed way. Also, the system stores the patch-based spatial structure patterns of time-series land cover maps in binary form to extract changes. This demonstrated that the proposed change detection system can be used as a basis for planning the reconstruction of the urban spatial structure by measuring the degree of urban sprawl.
