Background: Korea has experienced rapid economic development in a very short period of time. A mixture of traditional and modern risk factors coexists and the rapid change in non-genetic factors interacts with genetic constituents. With consideration of these unique aspects of Korean society, a large-scale genomic cohort study-the Health Examinees (HEXA) Study-has been conducted to investigate epidemiologic characteristics, genomic features, and gene-environment interactions of major chronic diseases including cancer in the Korean population. Materials and Methods: Following a standardized study protocol, the subjects were prospectively recruited from 38 health examination centers and training hospitals throughout the country. An interview-based questionnaire survey was conducted to collect information on socio-demographic characteristics, medical history, medication usage, family history, lifestyle factors, diet, physical activity, and reproductive factors for women. Various biological specimens (i.e., plasma, serum, buffy coat, blood cells, genomic DNA, and urine) were collected for biorepository according to the standardized protocol. Skilled medical staff also performed physical examinations. Results: Between 2004 and 2013, a total of 167,169 subjects aged 40-69 years were recruited for the HEXA study. Participants are being followed up utilizing active and passive methods. The first wave of active follow-up began in 2012 and it will be continued until 2015. The principal purpose of passive follow-up is based on data linkages with the National Death Certificate, the National Cancer Registry, and the National Health Insurance Claim data. Conclusions: The HEXA study will render an opportunity to investigate biomarkers of early health index and the chronological changes associated with chronic diseases.

This study analyzed the lesson analysis reports and survey of pre-service teachers who have practiced the microteaching in order to identify the reflection of mathematics pre-service teachers. The professors who are teaching pre-service teachers need to propose the examples of an instructional model that can induce the opened reaction and the effective usage of time through interesting topics. In addition, pre-service teachers who have practiced the first microteaching have shown a lot of reflection more than expected. Therefore, to improve the quality of lectures, it is important for pre-service teachers to have experiences of microteaching and reflection.

Objectives : The purpose of this study is to suggest how to interpret the 'practice of Korean Medicine', differentiating it from 'medical practice'. Methods : I analyze the legislations and precedents regarding the practice of Korean Medicine. Results : The Korean Medicine and Pharmaceutics Promotion Act defines 'practice of Korean Medicine' and it clearly differentiates it from the definition of 'medical practice'. However, the scope of this definition is somewhat restricting and it can violate doctors of Korean Medicine's right to equality and their academic freedom. Thus, the application of this definition of the 'practice of Korean Medicine' should be limited to the field of research and development. Meanwhile, criteria of distinguishing 'practice of Korean Medicine' from 'medical practice', which used to make a sharp distinction between Medicine and Korean Medicine by rigorously applying their academic standards, are now focusing more on protecting and improving health of the people. Discussions & Conclusions : I suppose that the distinction between the 'practice of Korean Medicine' and 'medical practice' will be more focused on public health rather than the academic stance of those two medical fields. Meanwhile, in accordance with dualistic medical system, the mutual usage of medical equipment in the area of 'treatment' should be limited while it should be allowed in the area of 'diagnosis' if it satisfies requirements suggested by the Constitutional Court.

In 1933, I. Schur introduced a Schur ring in connection with permutation group and regular subgroup. After then, it was studied mostly for purely group theoretical purposes. In 1970s, Klin and Poschel initiated its usage in the investigation of graphs, especially for Cayley and circulant graphs. Nowadays it is known that Schur ring is one of the best way to enumerate Cayley graphs. In this paper we study the origin of Schur ring back to 1933 and keep trace its evolution to graph theory and combinatorics.

The traditional earth wall structure consists of a Joongkit(a small reinforcing post inside a wall) and a Oe(a miscellaneous tree, rendered laths) based on the space between the columns and applying the soil. The members who act as the base layer before applying soil used joongkit, sakmok, and oemok, which are known to correspond to the current joongkit, gasisae, and lath strips. This study was designed to understand the following through an analysis of the ancient texts, such as uigwe. Through a study on the usage and specifications of joongkit recorded on the uigwe, I wanted to reveal that joongkit is a material that has different specifications, functions, and installation techniques from current joongkit. The purpose of this study was to present the differences and technical features of the components of use for two types of oeyeokki technique of traditional wall. In addition, the items to be considered at the actual cultural heritage repair site were reviewed in the restoration of the earth wall weaving technique.

The subjects of this study were limited to Silla buddhist temple remains in the 6~8th century, where the excavation survey report was published and the details of the remains of the corridor are revealed. Since the corridor completes the structure of temple and is involved in formation of the space, the building plan for corridors is thought to have an intention linked to the entire temple. Thus, more closer study is required for this construction plan to identify the role of corridors. The corridor is a building that has a low architectural hierarchy and completes the layout and composition of the temple. In the unit planning of the corridor, unit were designed to be of a certain size in the temple layout. Then, the overall scale was made by adding the fixed size of unit. The combination of corridors are the combined points of paths and were used as visual points. The structure of the corridor was constructed to be adjusted according to the size of the main compartment of the building to which it was connected and inserted under the roof of the building. The adjustment of the unit changed in the range of 0.5 to 2 of Silla's system of measurement. The usage of embedded pillar in the corridor presents a new perspective on Silla architecture.
