Diabetes is mainly evaluated by fasting blood sugar. The genetic and environmental factors influence the development of type 2 diabetes. In this study, the relationship between diabetes and family history of diabetes in Koreans was analyzed in consideration of body mass index and age. The study subjects were 4,274 subjects who received a medical examination at a university hospital. The main statistical analysis method was multiple logistic regression analysis. In addition, subjects were analyzed by dividing them by gender and the median of age and body mass index. Diabetes prevalence was 8.9% of all subjects, and subjects with a family history of diabetes were 14.5%. The risk of diabetes was 2.80 times higher in subjects with a family history of diabetes than subjects without a family history of diabetes. In addition, in younger subjects, the risk of diabetes was 3.36 times higher in subjects with a family history of diabetes compared with subjects without a family history of diabetes. In this study, the family history of diabetes was significantly associated with diabetes. The relationship between family history of diabetes and diabetes was slightly higher in the younger group than in the older group. In order to obtain an accurate assessment of the association between diabetes and family history of diabetes, further prospective cohort study in the future is necessary.

Investigating constructions of equations by Gou gu shu(勾股術) in Hong Jung Ha(洪正夏)'s GuIlJib(九一集), Nam Byung Gil(南秉吉)'s YuSiGuGoSulYoDoHae(劉氏勾股術要圖解) and Lee Sang Hyuk(李尙爀)'s ChaGeunBangMongGu(借根方蒙求), we study the history of development of Chosun mathematics. We conclude that Hong's greatest results have not been properly transmitted and that they have not contributed to the development of Chosun mathematics.

The retail store, which appears in various ways of the modern city, is the architectural result that the merchandise is finally delivered to consumers. The relationship between the commerce based on manufacturing and distribution and the retail store as urban architecture can be understood not only from the viewpoint of economics and business administration but also the problem of the formation of urban history and urban organization. The modern industrial development in Korea had been progressed by the state led, as the manufacturing and distribution developed in turn. This social and economic situation influenced the formation of the retail store of the city. This is different from the West, which the development has been conducted together. The cosmetics sales space, which is the subject of this study, has changed in various forms from the 1960s to the 1990s. Cosmetics brand retail shop is a corporate brand-based space, but paradoxically, it has a historical characteristic of urban architecture in that it is branding city street. This specificity of Seoul is unexplained by the development process of the Western and does not exist as a physically huge or special construction sometimes. However, it operates as a urban architecture in Seoul where the complicated.

Hypertension is associated with cardiovascular disease. The environmental and genetic factors can cause the development of hypertension. In this study, the relationship between hypertension and family history of hypertension in Koreans was analyzed in consideration of serum fasting blood glucose levels and age. The study subjects were 2,484 subjects who had a medical examination at a university hospital. The main statistical analysis method was multiple logistic regression analysis. Hypertension prevalence was 16.4% of all subjects, and subjects with a family history of hypertension were 23.5%. The risk of hypertension was 2.36 times higher in subjects with a family history of hypertension than subjects without a family history of hypertension. In addition, in the subjects with fasting blood glucose levels more than 120 mg/dL, the risk of hypertension was 4.44 times higher in subjects with a family history of hypertension compared with subjects without a family history of hypertension. The relationship between family history and hypertension was slightly higher in the older group than in the younger group. To assess the association between hypertension and family history, further cohort study is necessary in the future.

In this article, the theoretical basis of applying mathematical his tory in lessons is inquired in various educational aspects. It also covers the psychological genetic principle, mainly concerning the childish development and states that it has to be compatible with the historico-genetic principle, which is suggested mainly concerning the development of data. In addition, it evolves the arguments about the meaning of mathematical history in math lessons based on the mentioned aspects besides that in ordinary math lessons. Next, the link between the apply of mathematical history and education for gifted children is examined.

This paper is the result of a research conducted for "Knowledge Resource Development by Excavation and preservation and DB Establishment of Traditional Home Remedy", a part of Korean Medicine knowledge infrastructure establishment and Korean Medicine therapy development project executed by Korea Institute of Oriental Medicine. This paper is a part of the plans to standardize Korean acupuncture and moxibustion and surgical techniques in order to make new techniques derived from Korean traditional medicine patentable, as presented in the Nagoya Protocol. By first reviewing traditional text sources and classifying them into index literature and index techniques, we can see a mutual relationship between these two categories. Based on current research papers, this study has established a total of 121 pieces of index literature as well as extracted 64 types of index techniques in acupuncture and surgery technique. Both index literature and index technique have been concurrently visualized in this paper in the "Korean Acupuncture & Moxibustion Technique and Surgical Manipulation Base Map".
