Korean-Chinese is one of the 56 minority groups in the People's Republic of China. Korean-Chinese is the same origin as the Korean Peninsula. In the mid of 19th century, they, who lived in a part of Joseon, suffered with nature disasters and poverty, therefore they offended against the law, immigrated, and started farming in Ching Dynasty, which is northeast China in the present. Later, Korean's individual and mass migrations were happened around coastland of Tumen River and Yalu River with the connivance of the law. This thesis is a consideration of how the Korean-Chinese has adapted before and after the liberation from Japanese colonial era to the Chinese socialism and What their Residential Plan Composition and Plan Types in the village. Based on the field research and literature research, introduces the village history, Plan Composition and sample Plan types. Then, Based on this research, it will be the foundation of the future study of the Korean-Chinese's villages and planning study to conserve the villages.

In this study, a relationship between small-strain shear modulus ($G_{max}$) and overconsolidation ratio (OCR) based on shear wave velocity ($V_S$) measurement was established to identify the stress history of centrifuge model ground. A centrifuge test was conducted in various centrifugal acceleration levels including loading and unloading sequences to cause various stress histories on centrifuge model ground. The $V_S$ and vertical effective stress were measured at each level of acceleration. Then, a sensitivity analysis was conducted using testing data to ensure the suitability of OCR function for the tested cohesionless soils and found that OCR can be estimated based on $V_S$ measurements irrespective of normally-consolidated or overconsolidated loading conditions. Finally, the developed $G_{max}$-OCR relationship was applied to centrifuge models constructed and tested under various induced stress-history conditions. Through a series of tests, it was concluded that the induced stress history on centrifuge model by compaction, g-level variation, and past overburden load can be analysed quantitatively, and it is convinced that the OCR evaluation technique will contribute to better interpret the centrifuge test results.

Informational urbanism is a new research area in information science. In this study, art history joins informational urbanism: Are digital artworks in public urban spaces recognized as essential assets of a smart city? We employed case study research, working with the example of the huge digital media façade of the Arthouse Graz as an artwork in a public space. In a mixed-methods approach, we asked passers-by and interviewed experts on Graz as a smart city and on the Arthouse's role concerning the image of Graz as a smart city. The research found strong hints that indeed digital artworks with large screens or media façades at public spaces are parts of a city's weak location factors as well as of the city's urban structure and may symbolize the city's smartness. A practical implication of this finding is that artists, computer and information scientists, city planners, and architects should include interactive contemporary digital art into city spaces in order to demonstrate the city's way towards knowledge society.

In this study, a risk-appearance frequency evaluation model for railway level-crossing accidents is developed with the frequency estimation based on the accident history. It follows the worldwide common safety management approach and reflects the operation conditions and accident properties of the domestic railway system. The risk appearance frequency evaluation process contains a development of accident scenarios by defining the system configurations and functions, and a frequency estimation of hazardous events based on the accident history. The developed model is verified with the accident history during 5 years('03-'07) for 3 hazardous events: 'Being trapped in level crossing(Hl)', 'Crossing during warning signal(H2)' and 'Breaking through/detouring the barrier(H3)'. This risk appearance frequency evaluation model will be combined with a consequence evaluation model so as to offer full risk assessment for the railway accident. The accident risk assessment will contribute to improving the safety management of the railway system.

A settlement prediction method based on shear wave velocity measurements and soil nonlinearity was recently developed and verified by means of centrifuge tests. However, the method was only applicable to heavily overconsolidated soil deposits under enlarged yield surfaces. In this study, the settlement evaluation method was refined to consider the stress history of the sublayer, based on an overconsolidation ratio evaluation technique, and thereby incorporate irrecoverable plastic deformation in the settlement calculation. A relationship between the small-strain shear modulus and overconsolidation ratio, which can be determined from laboratory tests, was adopted to describe the stress history of the subsurface. Based on the overconsolidation ratio determined, the value of an empirical coefficient that reflects the effect of plastic deformation over the elastic region is determined by comparing the overconsolidation ratio with the stress increment transmitted by the surface design load. The refined method that incorporate this empirical coefficient was successfully validated by means of centrifuge tests, even under normally consolidated loading conditions.

The egg development and early life history of Korean endemic bitterling Rhodeus pseudosericeus were observed under the controlled water temperature, $17.0{\pm}0.5^{\circ}C$. Fertilized eggs are opaque yellow in color, measuring 2.9~3.1 mm in length and 1.6~1.9 mm in breadth. The eggs of this species began to hatch about seventy hours after insemination and the range of total length of larvae were 3.2~3.4 mm. The larvae reached at the heterotrophic stage about twenty-five days after hatching. R. pseudosericeus had a pair of wing-shaped yolk projection during the prelarval stage that is a common character of the genus Rhodeus.

For three years, from 2014 to 2016, in dental history class, 263 3rd grade students, attending postgraduate dental school had reviewed current problems of the dentistry and dental care system by adopting historical thinking, in forms of essays, editorials, and papers, The purpose of this study is to know whether writing has educational benefits on students. Analysis of the writings and Student course evaluation showed that it is beneficial. All of the students agreed on submitting a qualitative study project instead of taking midterms on 2016. The approval ratio has increased over the years, on 2014 being 82%, on 2015 being 98%, on 2016 being 100%. For that reason, it is not an assertion to deduce that the students have experienced benefits while developing their genuine thoughts on the current status or problems, exploring what their role is, and what they will face. The chronological thinking had been used throughout the researches to identify what Dentistry and Dentist is. Dentistry have encompassed knowledges of natural sciences, humanities and other fields when needed to perfect itself. In doing so, Dentist achieved independence from doctor or other cooperatives. Research on Korean Dental care system has involved in historical thinking, including historical analysis, inquisition, and historical imagination, insight. etc. If the in-depth evaluation consisting of history and writing is sustained, it would be very effective teaching method.

To explore the history of Korean engineers, one must navigate the field answering to the question of who engineers are. This is not an easy task because, behind the English expression of engineer, there are various names and even histories pertaining to technology related actors in East Asian countries including South Korea, and the meaning and status of these names are different from one another. Thus, the process and method of answering to the question of who engineers are becomes the path to understanding the history of Korean engineers. This study, therefore, attempts to suggest research questions that should be raised to study Korean engineers and to find research methodology suited for addressing those questions. Until now, not enough efforts have been made to create and expand interdisciplinary discussions and contacts for this area of study. This study has some theoretical difficulties of having to combine concepts with different problematique. Nevertheless, it aims to discuss how to conduct research, what questions should be posed to analyze the construction of Korean engineers and what research methodologies are suitable for such research, based on previous researches conducted in the field of social science. Answers to the quest are sought through genealogy, conceptual history, actor-network theory, and the notion of techno-national formation.

Objectives: The purpose of this investigation was to examine the association between endometrial cancer and possible etiological agents. Methods: A case-control study was conducted in Iran between March 2012 and May 2016. The demographic and reproductive factors of 205 women with endometrial cancer were compared, and 590 healthy cases were participated in the control group. For each endometrial cancer case, there were three controls, who were matched in terms of age and residence. The data were considered significant at $p{\leq}0.05$. Results: After adjusting the variables, the nulliparity (OR 6.23, 95% CI 2.86-13.59), the nulligravidity (OR 5.94, 95% CI 2.51-14.06), the positive family history of reproductive cancer (OR 4.97, 95% CI 2.33-10.59), the infertility history (OR 2.38, 95%CI 1.32-4.31), the obesity ($BMI{\geq}25$) (OR 1.71, 95% CI 1.16-2.52), the early menarche age (<12 years) (OR 2.10, 95% CI 1.17-3.75), and the hormonal contraception use (OR 1.69, 95% CI 1.15-2.49) were found to be associated with an increased risk of endometrial cancer. Nevertheless, the education level, the job of women, the marital age, the leisure activities, and the breast feeding were not found to be associated with the endometrial cancer after adjusting the variables. Conclusion: Scheduling of the screening program is vitally indispensable to identify endometrial cancer in women with nulliparity, nulligravidity and the positive family history of cancer. In addition, women with early menarche, those with the history of infertility, the obese ones, and those who use contraception pills need to be particularly aware of the potential risks.
