  • As the need for quantitative qualities of IT investment performance heightens, numerous research organizations are developing various measurement methods for the quantitative evaluation and its currency value conversion. Corporations utilizing these methods to evaluate IT investment performance are gradually increasing. However, working-level staff in the corporations that have introduced the quantitative evaluation can not assure if the evaluation sufficiently reflects the actual effect provided by IT since the results arising from the conversion of currency value can't be visibly confirmed. This study tries to identify whether the quantitative evaluation of IT investment performance can be explained in terms of the level of consumer satisfaction proven by the qualitative evaluation by analyzing the level of consumer satisfaction and quantitative evaluation of a case company and identifying the correlation between them. As the result of the case study, the following points have been concluded. Firstly, the currency value of IT effect correlates with the level of consumer satisfaction. Secondly, in order to come up with a rational currency value of IT effect, developing an indicator as well as managing data on currency conversion that will enable the internal system's efficiency to become more quantitative is essential. Thirdly, IT ROI is not appropriate to compare the performance between systems and is utilized as a measurement standard for each system's performance and efficiency. Lastly, quantitative evaluation is still inadequate in the evaluation of the system's strategic side, and consumer satisfaction can be utilized as a supplementary method.

  • We employ a hyperbolic tangent function to construct nonlinear transformations which are useful in numerical evaluation of weakly singular integrals and Cauchy principal value integrals. Results of numerical implementation based on the standard Gauss quadrature rule show that the present transformations are available for the singular integrals and, in some cases, give much better approximations compared with those of existing non-linear transformation methods.

  • Physiological activity and antioxidative activity of Maesangi(Capsosiphon fulvescens) extracts with distilled water or 95% ethanol were investigated. For the evaluation of physiological and antioxidative activities, some evaluation assay methods such as measurement of Hunter color value, chlorophyll a/b value, total phenolics, reducing power and thiobarbituric acid(TBA) value of soybean oil were used. Proximate composition and mineral contents of Masaengi were orders of crude protein>crude fiber>moisture>crude ash>crude lipid, and K>Ca>Mg>Na>P>Fe>Zn, respectively. In ethanol extract, the content of total phenolic compounds in Maesangi was determined to half times of that in Dasima(Laminaria). The reducing power of Maesangi-ehtanol extract was about 5 % of vitamin C and was lower than that of Dasima-ethanol extract. The TBA value of Maesangi-ethanol extract on soybean oil oxidation was about 47 % and 68.4 % to control in three and eight days oxidation, respectively. But TBA value difference was not observed significantly with the dosage below 5mL of ethanol extract.

  • The purpose of this study was to use pig blood plasma transglutaminase (TGase) combined with thrombin and fibrinogen as a binder, which was applied to restructured meat, and to investigate its effect on the restructured meat quality. Pig meat was obtained 10 h post mortem from a traditional market was ground using a 10 mm aperture plate. A binder admixture was added (TGase:thrombin:fibrinogen mixed as 0.5:1:20 (v/v/v) to which was added 12% of its volume of 0.25 M calcium chloride) at 0, 5, 10, 15 and 20% of meat weight. Measurements included cooking loss, shrinkage rate, shear value, total plate count, pH value, TBA value, color difference, tension strength and sensory evaluation. The results showed that ground meat containing 20% w/w of binder admixture had higher cooking loss, shrinkage rate and shear value (p<0.05). Addition of different percentages of binder admixture did not affect total plate count, pH value, TBA value, and sensory evaluation of restructured meat (p>0.05). Tension strength was increased with increased level of binder admixture. Addition up to 15% binder admixture to restructured meat showed better scores of sensory texture, flavor and total acceptability (p<0.05).

  • The purpose of this study is to investigate hand and sensibility of PET treated by Ultra-Violet (UV). The 4-channel PET knit fabric was treated by a self-made UV instrument in 5cm distance with different time frames-0min, 30min, and 90min. For hand evaluation, mechanical properties were measured by the KES-FB system. The environmental condition was controlled at 29$^{\circ}C$, 75% (R.H.)-summer standard climate. Twenty female students evaluated 'roughness', 'smoothness', 'wetness', 'stiffness', 'coolness', 'touch', 'preference', and 'comfort'. The outcomes of the experiment are as follows: The surface roughness of mechanical properties showed significant differences and the value of PET irradiated by UV for 90min was highest. The order of primary hand value such as NUMERI and FUKURAMI was in a following order-Untreated > 30min treated > 90min treated. Total hand value showed that PET irradiated by UV for 90min was appropriate for using summer fabric. The results of subjective sensibility were that the untreated and 30min treated PET were recognized as similar and had a good evaluation on 'comfort', 'preference' and 'the sense of touch'. This consequence disagreed with total hand value, because it was considered that subjects' hand sensibility was dependent on the feel of smoothness.

  • The purpose of this study is to explore how people's evaluation and preference on color palettes differ based on their cultural background. This study used the same color palettes developed by Youngsoon Park and Denise Guerin(1992). Fourteen representative adjectives are used to analyze the meaning evaluation and preference on the six color palletes. 425 undergraduate students are se-lected from Korea, Japan, U.S. and England and ques-tionnaire was used as survey instrument. The results show that there are significant differences among the four countries in the meaning evaluation and preferences on the color palettes and the characteristics of color palettes influence the differences among the countries. The differences among the countries decrease in case of color palettes composed of warm color with low or medium value difference and chroma difference, while the differences increase in case of color palette characterized by strong color contrast with high or medi-um value difference and chroma difference. The result of color meaning evaluation can be catego-rized into Western and Eastern culture. Korea and U.S., and Japan and U.S. showed significant differences in the most words and Korea and Japan showed similarities in the most words. Therefore it can be concluded that cul-tural backgrounds related to race, region and history in-fluence the color meaning evaluation and preference. Fur-ther study should explore the relationship between color and culture using more various color instruments such as color palettes in order to categorize the various aspects of culture.
