EduGame is suitable to create interesting and self-directed education environment. This paper develops edugame applicable to learning of History centered on Goguryeo history in elementary school. It is named to 'Bukbeol'. The main theme is that we must let elementary students to have a correct understanding about Goguryeo history. It is time to consider that China distorts Goguryeo history. To implement this game we have to consider the interesting elements in contexts and technology in order to overcome the formal combination of education and amusement. Bukbeol is developed with RPG making 2003(RPGツワ一ル2003) made by Enterbrain company in Japan. And this edugame is applied to students to investigate the degree of satisfaction. Results show the possibility for the study of history and necessity of graphic interface.

Structures in a nuclear power system are designed to be elastic even under an earthquake excitation. However a structural component such as an isolator shows inelastic behavior inherently. For the seismic assessment of nonlinear structures, response history analysis should be performed. In this study, the response of base isolation system was analyzed by response history analysis for the seismic performance assessment. Firstly, several seismic assessment criteria for a nuclear power plant structure were reviewed for the nonlinear response history analysis. Based on these criteria, the spectrum matched ground motion generation method modifying a seed earthquake ground motion time history was adjusted. Using these spectrum matched accelerograms, the distribution of displacement responses of the simplified base isolation system was evaluated. The resulting seismic responses excited by the modified ground motion time histories and the synthesized time history generated by stochastic approach were compared. And the response analysis of the base isolation system considering the different intensities in each orthogonal direction was performed.

This study is aimed to develop standard metadata model and develop elements and present the importance of oral history archives that contrast with literature history. The study analyzed standard metadata description elements that can express contents and forms of oral history archives as information. Furthermore, it designed Project, Management, Record, and metadata modeling as a Related record domain for the sake of building digital oral archives. Finally, the study gave shape to real oral history archives based on basic elements, details, and design principles of division elements.

The purpose of this study was to analyze the space of upper class housing in Andong through the oral life history of women in terms of sexual life. Even though the living was centered on women, the women of Joseon were alienated from the history. For this reason, the life history of head family housing was not recorded in the language of women, and often passed on orally. Also sexual life is a important part in daily life, but it is hard to be recorded or mentioned in Confucian society, and there is not much space research related to sexual life. Now there is not a lot of head family housing left, and the number of people who can tell the life history which is not recorded and the storyteller is also decreasing. From now on, I will record what I have experienced or passed through interviews of the residents living in head family housing and then analyze the characteristics of the sexual life.

Reliable strength assessment of the Liquefied Natural Gas (LNG) cargo containment system under the sloshing impact load is very difficult task due to the complexity of the physics involved in, both in terms of the hydrodynamics and structural mechanics. Out of all those complexities, the proper selection of the design sloshing load which is applied to the structural model of the LNG cargo containment system, is one of the most challenging one due to its inherent randomness as well as the statistical analysis which is tightly linked to the design sloshing load selection. In this study, the response based strength assessment procedure of LNG cargo containment system has been developed and proposed as an alternative design methodology. Sloshing pressure time history, measured from the model test, is decomposed into wavelet basis function targeting the minimization of the number of the basis function together with the maximization of the numerical efficiency. Then the response of the structure is obtained using the finite element method under each wavelet basis function of different scale. Finally, the response of the structure under entire sloshing impact time history is rapidly calculated by synthesizing the structural response under wavelet basis function. Through this analysis, more realistic response of the system under sloshing impact pressure can be obtained without missing the details of pressure time history such as rising pattern, oscillation due to air entrapment and decay pattern and so on. The strength assessment of the cargo containment system is then performed based on the statistical analysis of the stress peaks selected out of the obtained stress time history.

Objectives: To study symptom differentiation for yang deficiency and blood heat based on 117 psoriasis patients. Methods: Obtained frequency analysis (%), mean (%), and OR, CL(P-value) with prospective pre-post intervention design and multiple regression analysis. Results: There were no statistically significant differences as to sex, BMI, smoking and marital status, but there were statistically significant differences in variables of average age, family history, and alcohol consumption (P<0.05). There were no statistically significant differences in psoriasis symptoms as to initial age of onset, morbidity span, area of the initial onset, and the progression of psoriasis during the last three months of each patient. However, the type of psoriasis showed a statistically significant difference (p=0.011). While there were no statistically significant differences as to common cold, condition of psoriasis after recovering from the cold, skin condition, exercise, and seasonality, irregular perspiration showed significant difference (p<0.00). When confounding factors have been controlled the blood heat patient group as the comparison group, multiple regression analysis showed OR, CI(95%) of 1.06(0.31-3.63) for men, 0.28(0.08-1.06) for aged 30 to 49,0 and 0.18(0.04-0.80) for aged 50 and older. it was 0.06(0.01-0.7) for family history, 1.06(0.29-3.88) for drink alcohol, 19.90(2.53-156.7) for seasonality, and 10.28 (3.19-33.11) for perspiration problems. In these variables, Sex, age, smoking, and alcohol consumption showed no statistically significant results, but family history(p=0.049), seasonality(p=0.005), and irregular perspiration (p=0.017) were statistically significant. Conclusion: Family history, seasonality and irregular perspiration are the determining factors for yang deficiency and blood heat in psoriasis.

The Fagus Factory at Alfeld on the Leine in Germany, which was built in 1911 and 1914, is a well-known and very important object in the history of modern architecture. Alan Colquhoun mentioned that it is "prophetic of the 'objective' (sachlich) Modern Movement of the 1920s". Vittrio M. Lampugnani evaluated it as "a Pioneer building of the architectural Realism". Most of historian of architecture explain that these achievements were accomplished mainly by the master architect Walter Gropius and sometimes by his co-worker Adolf Meyer. Through investigating the background in the planning stage and the process of design it is to try to find out what is truly happened during the project time. Furthermore, historical meanings of the building in the modern architecture is reinterpreted in the following aspects; who or which elements have influence on the Fagus Factory? and what kind of problems can be caused by the digested architectural history?

Pavilions, follies, and installations provide a place with a new experience beyond that of simple garden architecture. From this point of view, this study tried to analyze the constructs in the Glass House site, which Philip Johnson has built for 50 years. After Chapter 1 Introduction, which summarized the background of the study, Chapter 2 investigated the design background of the landscape and the types of the constructs there. It also, studying literature on pavilions, follies, and installations, defined the basic meanings of them. Chapter 3 identified the features of each construct through the case studies of it, analyzing Johnson's intentions on it. These features are such as the applications of classical follies, the quotations of architectural history, fusion with art, architectural experiments, and the monuments of personal history. In conclusion, this study, finding the site specificity as a common feature of pavilions, follies, and installations, referred to two aspects of this, which are not only physical placeness but also cultural media.

In this study, the deformation, stress, vibration, fatigue life and the probability of damage are analyzed at the pedal applied by the force of 300N. The maximum stress at the lower of pedal is shown as 20.801MPa. And the maximum displacement is 0.85mm at the maximum response frequency as 3800Hz. Among the cases of nonuniform fatigue loads, 'SAE bracket history' with the severest change of load becomes most unstable but 'Sample history' becomes most stable. In case of 'Sample history' with the average stress of 0 to $-10^{5}MPa$ and the amplitude stress of 0 to $10^{5}MPa$, the possibility of maximum damage becomes 0.6%. This stress state can be shown with 5 times more than the damage possibility of 'SAE bracket history' or 'SAE transmission'. The structural result of this study can be effectively improved with the design of pedal by investigating durability against its damage.
