It has been recognized that the damage control must become a more explicit design consideration. In an effort to develop design methods based on performance it is clear that the evaluation of the nonlinear response is required. The methods available to the design engineer today are nonlinear time history analyses, monotonic static nonlinear analyses, or equivalent static analyses with simulated nonlinear influences. Some building codes propose the capacity spectrum method based on the nonlinear static analysis(pushover analysis) to determine the earthquake-induced demand given by the structure pushover curve. These procedures are conceptually simple but iterative and time consuming with some errors. This paper presents a nonlinear direct spectrum method(NDSM) to evaluate seismic performance of structures, without iterative computations, given by the structural initial elastic period and yield strength from the pushover analysis, especially for MDF(multi degree of freedom) systems. The purpose of this paper is to investigate the accuracy and confidence of this method from a point of view of various earthquakes and unloading stiffness degradation parameters. The conclusions of this study are as follows; 1) NDSM is considered as practical method because the peak deformations of nonlinear system of MDF by NDSM are almost equal to the results of nonlinear time history analysis(NTHA) for various ground motions. 2) When the results of NDSM are compared with those of NTHA. mean of errors is the smallest in case of post-yielding stiffness factor 0.1, static force by MAD(modal adaptive distribution) and unloading stiffness degradation factor 0.2~0.3.

Disaster of Sewol took place in one year. Meanwhile, the victim's family and the call time record academics have tried to record it. Ansan activists have moved to objectives such as civil records committee also pivotal. The citizens committee under the dictation recording oral history team has a diverse group of people associated with the time issue. bereaved families were collected from the oral as well as volunteers, religious personnel, activists, Ansan citizens and various people. Disasters around the world is also an important event to remember and honor the people together, and one of the most effective means to record There it is establishing an oral history archive. Does not leave a lot of nature history of sudden disasters that occur, as well as a tribute record dictation telling people of diverse perspectives on events helps a lot closer to the reality of the event. Erected in the National September 11 Memorial Museum to honor the Sept. 11 attacks and provide a variety of programs to chaerok dictation of the people involved with 9/11. To remember the 2013 Boston Marathon bombing 'Our Marathon' of crowdsourcing digital archive was built. In the archives of the local universities and institutions were created to collaborate actively and gathering oral history. Pan Am Flight 103 pieces terror has established an archive from Syracuse University. Here, neither graduates, faculty, and to the victim's family and friends gather and oral hitory. Disaster-related Sewol neither should be able to be used as in the case of foreign well, and it should continue to honor the victims of the collection. It also ought to occasion again to avoid this disaster on earth.

In this study, we investigated the methods of using the Cabri3D program for education of problem solving in school mathematics. Cabri3D is the program that can represent 3-dimensional figures and explore these in dynamic method. By using this program, we can see mathematical relations in space or mathematical properties in 3-dimensional figures vidually. We conducted classroom activity exploring Cabri3D with 15 pre-service leachers in 2006. In this process, we collected practical examples that can assist four stages of problem solving. Through the analysis of these examples, we concluded that Cabri3D is useful instrument to enhance problem solving ability and suggested it's educational usage as follows. In the stage of understanding the problem, it can be used to serve visual understanding and intuitive belief on the meaning of the problem, mathematical relations or properties in 3-dimensional figures. In the stage of devising a plan, it can be used to extend students's 2-dimensional thinking to 3-dimensional thinking by analogy. In the stage of carrying out the plan, it can be used to help the process to lead deductive thinking. In the stage of looking back at the work, it can be used to assist the process applying present work's result or method to another problem, checking the work, new problem posing.

Mobile games will be one of independent industries on game areas and take the fourth standing in the important platform since PC Games, TV Games, and Palm Games. There are several reasons why mobile games will differ in their platform, behaviors, and habits. According to the data of market consultation about the figure of mobile-game players throughout the world, the Mobile game will increase steadily from 780 million in 2007 to 1860 million in 2010. Also, market income will mount up from $42,100 million to $87,000 million. 3D games have been playing important roles in our lives. Satisfying users' needs in high-quality games, they have been growing and attracting more people with their powerful visual effects and the three-dimensional design player. We cannot emphasize their tremendous visual impacts and animation effects too much. This paper displays how to design 3D application based on J2ME (Java 2 Micro Edition) and shows free movement of 3D objects receiving and responding to the keyboard of mobile devices withWTK (Wireless ToolKit) simulator on the 3D screen.

The study has a purpose of understanding the factors that affect the oranizational commitment of the employees working in the libraries for visually impaired. To do this, the study chose personal background, emotional labor, role, job characteristics, organizational culture and organizational justice and attempted to find out how these factors affect the oranizational commitment. As a research method, mixed study method was used where quantitative analysis was complemented by qualitative analysis. For quantitative analysis, statistical analysis was conducted using the retrieved questionnaires. For qualitative analysis, the researcher had a one-on-one talk with the experts and employees who want to participate using an interview note was recomposed based on the survey responses. In the study results, emotional labor, job characteristics, organizational culture and organizational justice was proven to have influence on job engagement. To improve the job engagement, autonomy should be guaranteed by minimizing the organizational intervention to the assigned works and expanding the discretionary power. Furthermore, intensive management of the employees' emotional labor and fair process regarding the work performance is highly important.

Today, with countless health information being accessible through online and offline, the public has been able to explore health-related information in various ways. The current study focuses on the information-seeking behavior of the mothers who actively explore information related to the health of their healthy infants (aged between 0 and 3 years). The researcher had conducted in-depth interviews of 24 American, Korean, and Korean immigrant mothers living in the United States, and then analyzed the sequential order of the information sources that they have used to search for the health-related information about their children. The current research highlights that the mothers' information-seeking pathways and searched topics tended to differ in accordance with their child(ren)'s health conditions (e.g., ill vs. healthy). For instance, regarding the information sources used, more diverse health information sources (e.g., public libraries, government health agencies, daycare teachers) were used when their child(ren) was not ill. In addition, when a child was ill, mothers were likely to focus on information about specific diseases or symptoms first, whereas when the child was healthy, they used to explore information on various health topics such as growth and development, nutrition and diets, parenting, and so on. Based on the results, implications for the information professionals are discussed when designing and providing health-related information services to mothers of healthy infants and toddlers.

Interactive terrain visualization is an important research area with applications in GIS, games, virtual reality, scientific visualization and flight simulators, besides having military use. This is a complex and challenging problem considering that some applications require precise visualizations of huge data sets at real-time rates. In general, the size of data sets makes rendering at real-time difficult since the terrain data cannot fit entirely in memory. In this paper, we suggest the effective Real-time LOD(level-of-detail) algorithm for displaying the huge terrain data and processing mass geometry. We used a hierarchy structure with $4{\times}4$ and $2{\times}2$ tiles for real-time rendering of mass volume DEM which acquired from Digital map, LiDAR, DTM and DSM. Moreover, texture mapping is performed to visualize realistically while displaying height data of normalized Giga Byte level with user oriented terrain information and creating hill shade map using height data to hierarchy tile structure of file type. Large volume of terrain data was transformed to LOD data for real time visualization. This paper show the new LOD algorithm for seamless visualization, high quality, minimize the data loss and maximize the frame speed.

Stories have existed with the history of mankind along with drawings. Any genre of art that discusses the flow of time, such as literature, film, and play, cannot be free from narratives. The comics are not an exception. The comics tell the narratives with drawings from the cartoons in single blocks to the full-length series in tens of volumes. Nevertheless, there are not many studies that discuss the narratives in the comics. They may have been overlooked because they have been studied in the field of literature. However, I am envious of the field of film, which unravels the narratives with the same visual images, profoundly explores its own narratives and experimentally modifies and expands them into various levels. Therefore, I would like to make a narrative approach to the comics in this study. This study will discuss the non-narratives. It may sound ironic that the study of narratives will discuss the non-narratives, but the narratives cannot exist without the non-narratives. The non-narratives in the narratives compose the narratives in various ways. Therefore, Chapter II will discuss how the theory of narratives in literature classifies the narratives and the non-narratives as a theoretical background. Then, Chapter III will analyze the forms of non-narratives in Han Jo Kim's "The Texture of Memory" to discuss how the non-narratives of comics are composed, while Chapter IV will summarize the preceding studies. Finally, the narratives should be actively studied as it is an essential component of comics. I hope that this study can lay the foundation for more in-depth discussions of the narratives in the comics.
