In this study, the influence of the physical properties of ink such as ink dispersity and emulsified amount on the printability of a coated paper was investigated with seven kinds of cyan inks. In addition, two kinds of coating formulations were tested to evaluate the effect of coating structure on the coated paper printability. It was found that the cyan ink with $2{\mu}m$ pigment size had the best dispersibility and hence the ink showed a best ink density on the two kinds of coated papers. When the emulsified ink A with IPA 20 wt% had a lower viscosity than emulsified ink B with IPA 10 wt%, the emulsified ink A showed relatively high value of the ink transfer rate in comparison with emulsified ink B. Despite the high value of ink transfer rate, the coated paper did not show a good printability because those inks with low viscosity due to a strong emulsification were easy to make print mottle on the coated paper.

Shin-Ki-Hwan (Shen-Qi-Wan, SKH), Bo-Jung-Ik-Ki-Tang (Bu-Zhong-Yi-Qi-Tang, BJIKT), and Sa-Mul-Tang (Si-Wu-Tang, SMT) have been used for various kinds of deficiency syndromes, such as 'yang', 'qi', and 'blood', respectively. The objects of this study were to determine the effects of water extracts of three different kinds of traditional Chinese medicine (TCM), SKH, BJIKT, and SMT, on the anxiolytic activities in the elevated plus-maze test and to clarify the differences among 'yang', 'qi', and 'blood'. The water extracts of SKH, BJIKT, and SMT were orally administered to male SD rats, at 1.0 g/kg for 10 days. All rats were subjected to behavioral tests for the anxiolytic activity at 10 days. SKH, for the benefiting 'yang'agents, significantly increased the ratio of open arms entry to the total arms entry and time spent in the open arms (p<0.05), suggesting anxiolytic effect. However, both BJIKT and SMT decreased the ratio of open arms entry to the total arms entry and increased times spent in the closed arms (p<0.05). From these findings, it can be speculated that SKH only exhibits anxiolytic effect and that the different anxiolytic effects in the elevated plus-maze test may be come from the meanings of 'yang', 'qi', and 'blood'in oriental diagnostics though the cases are restricted.

The purpose of this study was to standardize the various methods and recipes of Hwajeun (glutinous rice pancake with flower) that appeare in the literature. For this purpose, the effects on sensory and physical characteristics of Hwajeun in various kinds of dipping syrups (S1 : honey, S2 : rice syrup, S3 : com syrup, S4 : sugar syrup and S5 : sugar) during storage for 24hrs were investigated. This experiment consisted of the measurement of water content, color difference meter, texture analyser and sensory evaluation for acceptance (color, flavor, moistness, softness, chewiness, adhesiveness, sweetness and overall acceptability). The moisture contents decreased with increasing storage time, indicating that S1 had a significantly (p<0.01) high value until 12hrs. The colorimetric values of lightness (L), redness (a) and yellowness (b) decreased and the total color difference values ($\Delta$E) increased with increasing storage time. In the two bite compression test, the hardness of S1 and S3 showed significantly (p<0.0001) lower values than other samples. As a result of the sensory evaluation for Hwajeun prepared with various kinds of dipping syrup, S1 and S3 were most preferred in color, flavor, moistness, chewiness, adhesiveness, sweetness and overall acceptability of sensory evaluation.

In this study, the alteration of Jook was studied by analyzing and comparing ingredients of Jook appeared in the reference of cookbooks from 1611 to 1958. 121 kinds of Jooks were mentioned 371 times. The Jooks made only with grains, mostly Hin Jook (white Gruel) made of rice, were recorded 31 times in 10 kinds. Rice or processed rice appeared most (194 times) as main ingredients in Jooks other than Hin Jook. As for condiments, honey and sugar were mentioned 37 times, accounting for one third of the condiments recorded as used for Jooks. The basic ingredient of Jooks were rice, but mostly the Jooks were named after the subsidiary materials. Chinese medicinal ingredients were most among the subsidiary materials; 35 kinds of them were mentioned 73 times. As regards the ingredients of the Jook, the other ingredients were added to the grain ingredients between the 17th century and the 19th century whereas only grains were put into Jook during the 20th century.

Two kinds of static and dynamic state estimation methods are newly discussed for the problem of the measurement disturbance of environmental low-frequency noise in the presence of wind-induced noise. First, the probability characteristics of wind-induced noise are discussed in the form of probability distribution conditioned by wind speed, based on the simultaneous observation of the wind-induced noise and wind speed near a microphone. Next, especially form the viewpoint of simplicity for practical use, two kinds of static and dynamic state estimation methods are discussed. The static estimation method using the information on wind speed is fundamentally supported by the conservation principle of energy sum. The dynamic one is the method by using a recursive digital filter with the parameters successively renewed by the information on wind speed. This can be also simplified by using well-know Kalman filter under the assumption of the Gaussian distribution. The effectiveness of proposed two estimation methods are shown through experiments under a breezy condition in the open filed.

This research suggests the development of simulator for a Simulation Test of a moving object's path generation and following. There are many kinds of moving objects in weapon systems, such as vehicles, missiles, robots and so on. So need tests of moving simulations during development process of weapon systems. To simulate a moving object, need an flexible path. So this report suggests a $B\acute{e}zier$ curve algorithm for generation of smooth curve path. And when new developments of weapon systems are started, many kinds of simulators are created. But, these simulators are not reused in other project because there are different kinds of development environment. So need to allow users to add specific features, And this report suggests using Dynamic Link Library(DLL).

Among the weather conditions on the Korean Peninsula, Changma is a notable phenomenon. This is because substantial amount of the precipitation on the Korean Peninsula tends to happen during the Changma season. But there are times when this tendency falls into whims. That's the case when it doesn't rain or rains only little during the Changma season. The Korea Meteorological Administration (KMA) describes this phenomenon as 'Dry Changma' - meaning . However, 'Dry Changma' is often regarded as an instance of contradicto in adjecto. Since the general public believe that 'Changma' means . This confusion often leads to distrust in meteorologists. In this paper, we would like to propose a reasonable solution to this conundrum by employing the conceptual resources of contemporary philosophy. First of all, I will make explicit the meaning of 'Changma' that the public and meteorologists think of. And then a brief explanation of the concept of natural kinds will be presented and the argument will be made that Changma is a natural kind. Next, we will discuss a view on natural kind terms advanced by Saul Kripke, a renowned philosopher. We will argue that in Kripke's view, the general public's thought that 'Dry Changma' is contradicto in adjecto is not correct. This will eventually lead to the conclusion that the meteorologist usage of 'Changma' is the correct one, which is thereby to be adopted by the public.
