The samurai has been viewed as the Oriental equivalent of the feudalistic knights of Europe ever since the Europeans of old first landed on the shores of Japan in the 16th century. This comparison was not only because of their positions as the military class of their respective societies, but also because of the similarities in ethics and morality causing them to personify the concept of chivalry. The code of moral principles, based on the influences of Confucianism, Buddhism, and Shintoism, which the samurai was either instructed or required to observe, is called Bushidō or the Way of the Samurai. By the application of the theory of conceptual history, the study analysed the three works The Book of Five Rings by Miyamoto Musashi, Hagakure – The Way of the Samurai by Yamamoto Tsunetomo, and Bushido – The Soul of Japan by Inazo Nitobe. The purpose of the essay was to analyse and discuss how bushidō has been defined and explained by the three sources written in different time periods and how these three authors differ in their definitions of bushidō. Furthermore, the definitions were contextualized based on the societal changes of Japan between the time of writing the sources. The results showed how the authors focus on different aspects of what is included in bushidō and how the samurai was supposed to act for the benefit of society. Musashi added more focus on the way the samurai was supposed to excel on the battlefield. Tsunetomo, however, wrote his work while peace in Japan had established itself and thus focused on how the samurai was supposed to behave outside of the battlefield. Nitobe’s definition of bushidō also showed implications of a change in society based on how he chose to explain the concept of what bushidō was, and how it had evolved without the knights who had fostered it. Lastly, the study was discussed within an educational context. The samurai have seen a rise in popular history through games, film, advertisements, and more, and thus the curiosity of students, not only in Oriental culture, but Japanese culture in particular has been acknowledged. Therefore, teachers need further development of their own knowledge within the field of Oriental culture, which this study hopefully succeeds in.

As more studies accumulate on the impact of diabetes mellitus on the central nervous system, they resound with the same conclusion - diabetes has a detrimental effect on cognition regardless of the presence of comorbidities. Less consistent however, are the specific mental processes wherein these declines are noticeable, and the structural changes that accompany these reductions in mental capacity. From global atrophy to changes in the volume of gray and white matter, to conflicting results regarding the effects of hypo- and hyperglycemic states on the development of the hippocampus, the studies display a variety of results. The goal of this research is to link the structural and compositional changes occurring in the diabetic brain with the clinical and behavioral findings highlighted in the literature, as well as to explore the potential mechanisms behind the pathologic brain state of diabetic encephalopathy. Using diabetic (OVE26) and non-diabetic wild type (FVB) mice as models, differences in the number of hippocampal neurons in the dentate gyrus, and cornu ammonis areas 1,2, and 3 were investigated through Nissl staining. Neurodegeneration was confirmed in those cells determined to be hyperchromatic in the diabetic model through staining with Fluoro-Jade C. Finally, the presence of progenitor cells in the hippocampus was compared in the diabetic and non-diabetic models using Musashi-1 antibodies, to determine whether neurogenesis in these areas is affected by diabetes. These experiments were performed to better understand the effect of DM on learning and memory, and could potentially explain the linkage between diabetes mellitus and the increased prevalence of Alzheimer’s disease, vascular dementia, and depression in this subset of the population.
