Stress history increases in penetration resistance due to the increase in residual horizontal stress of granular soil. This study analyzes the effect of stress history on the results of CPT and DMT from calibration chamber specimen in OC as well as NC state. Test results show that the normalized cone resistance by mean effective stress correlates well with the relative density and the state parameter, whereas the normalized cone resistance with regard to vertical effective stress is a little affected by stress history. The horizontal stress index($K_D$) in DMT more reflects the influence of stress history on granular soil than the dilatometer modulus($E_D$) and cone resistance($q_c$). The $K_D/K_0$, in which the effect of stress history on $K_D$ is compensated by the at-rest coefficient of earth pressure, $K_0$, is related to relative density, state parameter and the normalized cone resistance by mean effective stress. It is also observed that the normalized dilatometer modulus by mean effective stress($E_D/{\sigma_m}'$) is unique correlated with the state parameter, regardless of stress history.

Objectives: We evaluated the reliability of the possible covariates of the baseline survey data collected for the Epidemiological Investigation on Cancer Risk Among Residents Who Reside Near the Nuclear Power Plants in Korea. Methods: Follow-up surveys were conducted for 477 participants of the cohort at less than 1 year after the initial survey. The mean interval between the initial and follow-up surveys was 282.5 days. Possible covariates were identified by analyzing the correlations with the exposure variable and associations with the outcome variables for all the variables. Logistic regression analysis with stepwise selection was further conducted among the possible covariates to select variables that have covariance with other variables. We considered that these variables can be representing other variables. Seven variables for the males and 3 variables for the females, which had covariance with other possible covariates, were selected as representative variables. The Kappa index of each variable was calculated. Results: For the males, the Kappa indexes were as follow; family history of cancer was 0.64, family history of liver diseases in parents and siblings was 0.56, family history of hypertension in parents and siblings was 0.51, family history of liver diseases was 0.50, family history of hypertension was 0.44, a history of chronic liver diseases was 0.53 and history of pulmonary tuberculosis was 0.36. For females, the Kappa indexes were as follow; family history of cancer was 0.58, family history of hypertension in parents and siblings was 0.56 and family history of hypertension was 0.47. Conclusions: Most of the possible covariates showed good to moderate agreement.

In 1607 a delegation was dispatched from Chosun to Japan (under the condition that prisoners of war were returned) to restore the destroyed relationship between the nations due to a war and to restore economic profits. This delegation later on became a delegation representing faith in each other. It contributed greatly to the Korea-Japan cultural exchanges in the 17th and 18th centuries. It was also a cornerstone for the exchange of Korea's distinguished studies as well as medical technology and Japan's results of international trade such as sweet potatoes, pepper, and tobacco. This thesis is one that discusses the study of documents produced during this process.

This research analyzes the involvement of hermeneutics in architectural history and theory studies and its pedagogy in the West after the 1950s. The research focuses on representative architectural schools in the West. In particular, this paper examines from the curricula of Joseph Rykwert and Dalibor Vesely at the University of Essex to their former students who played a significant role in expanding the history and theory courses in the late 20th century in the North America such as Alberto $P{\acute{e}}rez-G{\acute{o}}mez^{\prime}s$ (McGill University) and David Leatherbarrow (University of Pennsylvania). Through their leadership and other related architectural historians' efforts: 1) hermeneutics have been applied in architectural history studies from the critical perspectives of post-modern philosophy; 2) hermeneutics help stimulate discussions of thoughtful architectural design, enabling strong interactions between design theories and the embodied meanings of buildings; 3) these schools have produced and involved many prominent scholars who actively practice and develop the discourse of architectural history and theory from the perspectives of hermeneutics; 4) Finally, the hermeneutic approach in architectural history studies has enlightened many achieved architects' thoughtful design practice and theories within the emerging context of regional criticism and international cross-cultural architecture.

Objective ; This Study was carried out to review the history of acupuncture & moxibustion in Korea under the control of imperialized Japan and to compare the history among Korea, China and Japan. Results ; Under the control of imperialized Japan the science of acupuncture & moxibustion in Korea has experienced the dark ages because of the momentary disordered medical laws made by Japan. As we compare the history of acupuncture & moxibustion among Korea, China and Japan, Korea was simple but systemic, China was complicate but complex and Japan was nearly surgical. Conclusion ; The science of acupuncture & moxibustion of Korea was mostly advanced in the late Chosun and did not just imitate that of China and has advanced uniquely.

The function of history is divided into two: justification and reflection. Justification confers causality on the consequences of history, and thereby putting emphasis on the inevitability of present. From the perspective of reflection, on the other hand, history is what is selected from several possibilities, and in this respect, present is not necessarily inevitable. The former is conservative; the latter, reformative. History, however, takes both of the functions. History reproduces a community by preserving memories of the community through a record, and leads to the evolution of a community through reflection. Emerged in the precess of industrialization, Korean design, despite its relatively short history, is witnessing a growing desire to prove its existence through history. While, it is also noteworthy that there is an increasing interest in looking at the history of Korean design from the perspective of reflection. I propose four propositions necessary to study of the history of Korean design. They are as follow; 1) History is interpretation; 2) The history of the institution should be overcome; 3) A simplifying progressive view of history should be restrained; 4) Foundation for study should be established.

The purpose of this study was to investigate the distribution and correlation of stroke risk factor according to age with stroke patients. This study was based on clinical data registered in Daejeon Oriental Medical Hospital from November 2006 to December 2010. Study subjects consisted of 779 patients with stroke within 1 month and they were classified according to age and existence of past history such as hypertension, diabetes mellitus, ischemic heart diseaseand stroke family history. Stroke family history was distributed differently according to age unlike past history and in their 50's showed a particularly high rate. There was not statistically significant correlation between stroke family history and past history except for only between stroke family history and diabetes mellitus in the patients in their 80's and more. There was statistically significant correlation between hypertension and diabetes mellitus and especially in the patients in their 60's and 70's. There was statistically significant correlation between hypertension and ischemic heart disease and especially in the patients in their 80's and more. There was statistically significant correlation between diabetes mellitus and ischemic heart disease in the patients in their 60's. There was statistically significant correlation among hypertension, diabetes mellitus and ischemic heart disease, but stroke family history and past history had independence, so management and research for this subject should be required further and further.

Nearly every country in the world now has the education of its own history in school curriculum. Although there is a difference in the nationality of each country, each has a common perception that history education is important. This is because everyone agrees that the nation's national identity is the core of its identity, and that it forms the backbone of national unity. In Korea, history textbooks were temporarily organized in selective courses and until recently were chosen as subjects of choice in the CSAT. However, despite the repeated neglect of national history education, the national sentiment should not always be neglected, and the formation of the national consensus will eventually prove to be a necessity for the Korean National University's CSAT. Despite the need for the education of Korean history, education has always been mentioned in conjunction with the word "crisis" and "stalemate". This article looks at the key issues in the history of the curriculum and the contents of history textbooks.

This article intends to establish a online service of oral history archives. Unlike common records, it is important to understand the contextual relation of oral history archives. The context of oral history archives can include the context of oral history contents in addition to the connection with records produced in the process of performing work function of agency which performs collecting oral history archives, and the connection between oral history archives formed in the process of collecting oral history archives. Therefore this article emphasizes that the context of oral history archives has an important role and function in on-line service of oral history archives by researching the plan for on-line service of oral history archives based on the context of oral history archives.

The history of Korea's overseas construction began in 1965, and the cumulative contract amount is about $180 billion over the last 40 years. During the period, Korea's overseas construction industry has played an important role for economic development. However, it seems that the industry is in a sea of trouble. Overseas construction orders have declined due to various reasons such as companies losing confidence, limited financing, lack of competitiveness, and so on. This paper addresses the brief history of Korea's overseas construction industry and the problems that the industry is facing. Then it suggests a few measures for the improvement of the industry.
