The purpose of this study is to discuss and analyze the effect of blood glucose on treadmill exercise, functional food and their combined treatment protocol on diabetic rats. These group were divided treadmill exercise group(n:12), functional food feeding group(n:12), treadmill exercise with functional food feeding group(n:12) and control group. The following results were obtained from this study. 1. The blood glucose level was showed significantly different in several group, treadmill exercise with functional food feeding group are most significantly on other group. 2. The inhibitory rate of body weight was not significantly different on each group. 3. The amount of feeding was not significantly in several group. 4. The Islets size and Connective tissue proliferation was showed significantly different except control group, treadmill exercise with functional food feeding group are more significantly than other group. These results show that treadmill exercise with functional food feeding and their several protocols can retard the setreptozotocin-induced dibetic rat.

Ferrule is widely used as fiber optic connecters. In fiber-optic communications, the shape accuracy<br/> such as coaxiality and cylindricity of ferrule affects insertion loss. When coaxial grinding of ferrule<br/> supported by two pin, pin alignment and chucking accuracy are very important. In this research, the<br/> kinematic behavior of the ferrule center is investigated in the case where cone-shaped center pins and<br/> round circle holes which make contact with each other near the edge of the holes, using<br/> homeogenous coordinate transformation and numerical analysis. The obtained results are as follows: The<br/> alignment errors between center holes cause a sinusoidal displacement of ferrule. And the maximum<br/> displacement of ferrule centers increase in proportion to the center pin angle. The relationship between<br/> center pins displacement in coaxial grinding and grinding accuracy was explained.

In the past, OTT services are simply provided through TV set connected STB(set-top box). Recently, they can be however served through various devices such as smartphones, tablet PCs. And also, the range of contents, provided by OTT services, is extended from moving pictures to various kinds of information related to weather or news, communications including SNS, and internet games, and so forth. In order to analyze this rapidly evolving OTT service market situation, it is preferentially need to analyze the users’ behavior patterns. In this study, we wanted to provide fundamental data that can contribute to the strategy for efficient development of OTT service market by analyzing empirically the users’ behavior patterns in domestic OTT service market. Two surveys were conducted to separate two layers, using an online survey. The results of the surveys showed that the contents, platforms, and terminals were derived from the primary layer, and a total of 11 details were derived from the secondary layer. These results were analyzed through AHP. In the first survey, we found the latter is classified into several factors for choosing OTT services, based on each type of the first layer. Then, we formed a hierarchical structure of preference factors for OTT services in the domestic market. Through the second survey, AHP analyzed the priorities of preference factors. To sum up, we found the second preference for the OTT service in the first phase and determined the priorities of preference factors within the hierarchy and deduce the OTT service selection trend in the local market.
