  • To achieve these goals constituent dimensions and structural elements of the Japanese restaurants service quality are being investigated through the review of the food service industry and service. The survey about the importance and the Japanese restaurants was also conducted with a questionnaire to identify the tendency of customers who visited restaurants. These results and satisfactions hypotheses are being tested in the restaurant and the empirical research aye both conducted to achieve time research purposes. Japanese restaurants, located in the metropolitan area, are being selected as the object limits of the survey. Eighty-seven questionnaires are being distributed three kinds restaurants which means total 250 for all, and from which 230 are being analyzed. Frequency and $\chi$$^2$test were applied for the general matters and the conditions of object while Cronbach's Alpha coefficient and factor analysis were applied for reliability and validity. t-test was attempted to fine the importance and the satisfaction of the service quality. Also ANOVA was utilized. After examining the results of this survey, few facts were apparent. First the number of male ana female customers in the Japanese restaurants are divided evenly in about 55% of male customers and 45% of female customers. However, these people have a wide variety of jos. Another evident fact present on this survey shows that customers eating at a less expensive restaurants have a income of 1,000,000 won where as the expensive or high-end restaurants have customers with higher income than average. The price sensitive customers studied in this survey shows that they spend on average 30,000 to 70,000 won per person in the less expensive establishments. Therefore, with some service quality restructuring, application of new systems and ideas these restaurants could efficiently maximize their profit margin. Customers also showed that lower prices in lunch time would be an appealing incentive to deviate from standard lunch time 〈12:00~13:00〉and menu specials would be of interest to deviate from busy dinner time. In conclusion, since restaurants in the middle range category are not so many restaurants in lower range have a chance to maximize their profit. This study clearly shows that even the lower-end restaurants could raise their profit margin by incorporating new marketing techniques and by improving the service level of their restaurants.

  • The correlation between NiO-YSZ microstructure and its electrical property used for SOFC anode was critically evaluated with image processing and direct measurement techniques. These innovative processing techniques were employed to quantify the contiguity of the anode constituent phase. The calculated contiguities were then correlated with electrical conductivity attained from 4-probe DC method. This investigation described that contiguity of nickel oxide phases of an anode has a linear relationship with its electrical conductivity. We observed that the contiguity of NiO increased from 0.18 to 0.50 then electrical conductivity attained was significantly increased from 520 S/cm to 1468 S/cm at $900^{\circ}C$.

  • Manganese hydrogen phosphate hydrate, $MnHPO_4{\cdot}2.25H_2O$, is a major constituent of the pre-conditioning compositions for the manganese phosphate coating treatment over carbon steel substrate. This compound is conventionally produced by the synthesis in the aqueous solution process followed by the filtration and drying processes and a series of size reduction and classification processes in dry state. However, it is evident that the conventional process is neither environment-friendly nor cost-effective. In this work, a new process principle was examined based on the controlled double-jet precipitation technology to produce the manganese chemical product of fairly uniform particle size distribution in an aqueous solution media. The effects of stabilizing agents were comparatively studied by the scanning electron microscope analysis in a uniformity point of view of the resulting particle size. Polyvinylpyrrolidone and Gum Arabic were excellent in controlling the crystal growth step, resulting in fairly uniform size distributions of the particles from the controlled double-jet process.

  • The purpose of this study is to estimate the stochastic monthly runoff model for the Kunwi south station of Wi-stream basin in Nakdong river system. This model was based on the theory of Box-Jenkins multiplicative ARlMA and the state-space model to simulate changes of monthly runoff. The forecasting monthly runoff from the pair of estimated effective rainfall and observed value of runoff in the uniform interval was given less standard error then the analysis only by runoff, so this study was more rational forecasting by the use of effective rainfall and runoff. This paper analyzed the records of monthly runoff and effective rainfall, and applied the multiplicative ARlMA model and state-space model. For the P value of V AR(P) model to establish state-space theory, it used Ale value by lag time and VARMA model were established that it was findings to the constituent unit of state-space model using canonical correction coefficients. Therefore this paper confirms that state space model is very significant related with optimization factors of VARMA model.

  • Objectives : Taraxaci Herba et Radix (THR) is widely used as a food and medicinal herb in Korea. It has been used for treatment of virus inflammatory disease, liver diseases and gastritis. So far, anti-inflammatory effects and constituents of various species in THR has not been studied for comparison. The aim of this study is to compare the anti-inflammatory effects of the aerial part and root from various THR. Also, we have compared the contents of its known constituents with each. Methods : In this study, we estimated anti-inflammatory effect and compared their constituent by HPLC. For the determination of anti-inflammatory effects, we investigated NO and $PGE_2$ production by ELISA. The expressions of iNOS was determined by western blotting in LPS-induced RAW 264.7 macrophage cells. And, standard compounds which are methyl gallate, gallic acid, syringic acid and esculetin of THR were analyzed by HPLC using a $C_{18}$ column. Results : Methanol extracts of THR decreased NO and $PGE_2$ production. The expressions of iNOS protein were also decreased in methanol extracts of THR. As a result, HPLC analysis showed that they showed similar patterns. Methyl gallate and esculetin showed the highest content. Methyl gallate was included over 10% content in each aerial part and root of THR. Conclusions : These results indicate that most of THR distributed in Korea might represent therapeutic agent for treatment of inflammatory diseases.

  • It is well known that the sound characteristics of Korean bell depend on the shape and the alloy constituents. Development of the methods to acquire exact shape data and alloy constituents of the whole body of the bell is very important for the study and systematic management of Korean bells. The practical scanning and modeling methods to get shape data from optical triangulation laser scanners are proposed. The 3D shape data by the proposed methods can be the basis of diverse measurements such as curvature, volume, thickness and the distance between any two points. A nondestructive alloy constituents measuring method which can overcome the limitations of partial data collection and damages to Korean bells is also suggested to get the whole alloy characteristics. Following the developed methods, the data of the shapes and alloy constituents of 18 Korean bells are collected and the errors of existing measurement data for the shape have been corrected.

  • Gastrodia elata has been widely used as a traditional medicinal herb. However, in Korean Pharmacopeia, neither a marker constituent nor an analytical procedure for G. elata has been established. In this study, we suggest gastrodin and gastrodigenin as marker constituents of G. elata, and propose an analytical procedure for simultaneous quantification of these constituents by high-performance liquid chromatography-ultraviolet spectroscopy (HPLC-UV). The analytical method was validated for its linearity, precision, accuracy, and specificity. Based on the validated method, gastrodin and gastrodigenin in 14 commercial G. elata samples were quantified.
