  • 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.

  • The purpose of this paper is to explore a new methodology for the historiography of Korean cos-tumes. In particular, I focus on the possibility for systematic, historical methods appropriate for the history of Korean costumes. First, I characterize the general historiography of costumes as involving two aspects-one as the social science and the other as historical science(Geschichteswissenschaft). My contention is that any historical study of costume should be established on the intersection of social and historical studies, and their entangling relations with many a neighboring field of sciences. It requires in other words, an interdisciplinary approach that combines various methodologies of social sciences as well as those of history. Second, I present an overall review of the historical methodology with a special emphasis on the“Quellenkunde”of orthodox historiography. Building on the review, third, I pay attention to recent innovations in historical methodologies, such as“New History”that draws on history, sociology and social history, and their applicability to the history of Korean costmes. In this regards. I adress among others, the following theoretical perspectives : 1) comparioson and comparative history, 2) the formatived and paternal approaches toward the history of costume, 3) particulartiy and universality of Korean costume. I conclued that the history of Korean costumes should broaden its theoretical horizon in order to accomodate a wider range of research agenda, including costumes of neighboring cultures, while remaining sensitive to new theories and methods of the neighboring social historical sciences. For this purpose, it is emphasized that an international collaboration among researchers of the region, as well as that across the different disciplinnary boundaries, is indispensable for successful studies that can embrace diverse fields and areas.

  • This survey is the second part of the history of science of Song and Yuan dynasties and will covers the period from Jin to Yuan. Following the first part, we look at the calendrical astronomy, mathematics and medicine. In this survey we again follow Yabuuchi's work on the history of science of Song and Yuan period and Du Shiran's work on the history of science of China. We start from the sciences and mathematics of Jin which inherited those of Northern Song and see how they influenced the whole China including Yuan and Southern Song. As a conclusion the tendency to practical usages in the Southern Song as well as the suppression of Han people in Yuan prevented developments of theoretical sciences in Yuan and Ming later.

  • This study presents a new conceptualization of the history of Islamic astronomy. Islamic history is an embedded global cultural phenomenon and will be analyzed at different levels: a) the history of institutional aspects (observatories, including buildings), b) instruments, c) manuscripts, and d) scholars. This phenomenon will be analyzed as a multi-lingual phenomenon with Arabic as the language of sciences as a starting point. Although this is not a study of a geographical region in a narrow sense, it is a historical note on the entanglement of research written in Arabic, Persian and other languages and contextualized in a framework reaching geographically far beyond the confines of the Islamic world and being part of global history.

  • A macroscopic cross section generation model was developed for the conceptual horizontal, compact high temperature gas reactor (HC-HTGR). Because there are many sources of spectral effects in the design and analysis of the core, conventional LWR methods have limitations for accurate simulation of the HC-HTGR using a neutron diffusion core neutronics simulator. Several super-cell model configurations were investigated to consider the spectral effect of neighboring cells. A new history variable was introduced for the existing library format to more accurately account for the history effect from neighboring nodes and reactivity control drums. The macroscopic cross section library was validated through comparison with cross sections generated using full core Monte Carlo models and single cell cross section for both 3D core steady-state problems and 2D and 3D depletion problems. Core calculations were then performed with the AGREE HTR neutronics and thermal-fluid core simulator using super-cell cross sections. With the new history variable, the super-cell cross sections were in good agreement with the full core cross sections even for problems with significant spectrum change during fuel shuffling and depletion.

  • Background: A cancer survivor is defined as anyone who has been diagnosed with cancer, from the time of diagnosis through the rest of their life. The purpose of this study was to examine whether physical functions, health-related outcomes, nutritional status and blood markers in community-dwelling cancer survivors aged 75 years and older are different from those who do not have cancer Materials and Methods: Two hundred seventy-five participants were asked by physicians, nurses, and physical therapists, questions regarding cancer history in a face-to-face interview. Data were collected for demographic information, physical functions, such as handgrip strength, knee extension power, abdominal muscle strength, static standing balance, walking speed and the timed-up-and-go test, health-related outcomes, nutritional status, and blood markers. The measured parameters of survivor diagnosed with cancer were compared with those without a history of cancer. Results: Thirty-seven older adults were previously diagnosed with cancer. Female cancer survivors had lower knee extension power (p<0.05), abdominal muscle strength (p<0.05), walking speed (p<0.05), timed-up-and-go test score (p<0.05), and time to spend on walking per day (p<0.05) than older women without a history of cancer. In men, none of the measured parameters were significantly different between cancer survivors and older men with no history of cancer. Conclusions: The present study shows that partial physical function of women cancer survivors aged 75 years and older differs from that in women with no history of cancer.

  • The purpose of this essay is to survey the present situation of christian museums and to suggest future direction on the basis of the former result. Firstly, I arranged the present situation of protestant museums as a basic work to secure the importance of religious museums. And I will continue researches about catholic, buddhist, folk museums etc. A christian museum is important in that it is a storehouse of precious data accumulated in the history of modern Korea. However, interest in its value has not been given sufficiently so far despite its importance. Most christian museums are petty in their scale and management. When we consider the historical weight of christian history in the modern Korea, the status of christian museums have to be improved from now on. I classified the types of christian museums in Korea into christian history museum, christian art museum, biblical archeology museum, local churches' history museum, christian figures museum(memorials of famous christians), and mission school(colleges) museums on the basis of contents they possess. It can be said that the representative types among these are christian history museum and biblical archeology museum.

  • Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined by impairments in social interaction and verbal and nonverbal communication. Purpose: Determine the association between use of assisted reproduction technology (ART) and the risk of ASD among children. Methods: This case-control study included 300 participants (100 cases, 200 controls). The control group included women with a child aged 2-10 years without ASD, while the cases were women with a child aged 2-10 years with ASD. We used a researcher-made questionnaire. Data were analyzed using Stata ver. 14 at the 0.05 significance level. Results: In the univariate analysis, there was significant association between child sex, delivery mode, history of preterm delivery, history of using ART, and maternal age at child's birth and the risk of ASD. After the adjustment for other variables, this association was significant for male sex (2.66; 95% confidence interval [CI], 1.11-4.31; P=0.001) and history of using ART (4.03; 95% CI, 1.76-9.21; P=0.001). Therefore, after the adjustment for confounder variables, there was no significant association between ART and the risk of ASD among children (4.98; 95% CI, 0.91-27.30; P=0.065). Conclusion: After the adjustment for other variables, risk factors for ASD were male sex and history preterm delivery. Thus, there was no significant association between ART and the risk of ASD among children.

  • Golestan province has a reputation for relatively high incidence rates of gastric cancer in Iran. Along with dietary, lifestyle and environmental influential factors, soil selenium and high levels of pesticide used may exert influence in this region. The present study was designed for modeling the influential predictors on incidence of gastric cancer in Golestan. All registered cases of gastric cancer from March 2009 to March 2010 (49 females and 107 males) were investigated. Data were gathered by both check list and researcher made questionnaire (demographic, clinical and lifestyle characteristics) and analysed using logistic regression. Mean (${\pm}SD$) age at diagnosis was $62.9{\pm}13.8$ years. CIR and ASR of gastric cancer showed 9.16 and 13.9 per 100,000 people, respectively. Based on univariate logistic regression, a history of smoking (OR= 2.076), unwashed hands after defecation (OR= 2.612), history of cancer in relatives (OR= 2.473), history of gastric cancer in first-degree relatives (OR= 2.278), numbers of gastric cancers in first-degree relatives (OR= 2.078), history of X-ray and dye exposure (OR= 2.395), history of CT scan encounter (OR= 2.915), improper food habits (OR= 3.320), specific eating behavior (OR= 0.740), consumption of probable high risk foods (OR= 2.942), charred flesh (OR= 1.945), and animal fat (OR= 2.716) were confirmed as a risk factors. Changes in lifestyle may be expected to increase gastric cancer incidence dramatically in the near future. Therefore, appropriate educational interventions should be designed and implemented by competent authorities.
