This study focused on the evaluation of the quality and sensory characteristics of salad dressing prepared from soy powder (Gochujang), in order to increase the level of usability for the Gochujang which is the representative seasoning and spice of Korea. The moisture content and pH of the salad dressing increased in proportion to the increasing amount of soy powder (Gochujang) (p<0.001). Regarding the sugar and salt contents, 20% of the soy powder (Gochujang) shows $26.17^{\circ}Brix$, While the largest value for salt content was 4.8%, with a significant difference existing among varivous samples (p<0.001) As the added amount of soy powder (Gochujang) increased, the sugar content of the salad dressing increased with a statistically significant change (p<0.001). Regarding chromaticity, when soy powder (Gochujang) was added the levels of lightness and yellowness showed a decreasing tendency, and the level of redness showed an increasing tendency, with a significant difference existing among various samples(p<0.001). The results of a sensory showed that, as the amount of added soy powder (Gochujang) increased, the color intensity, Gochujang flavor, and hot taste increased (p<0.001). The results of a sensory showed that, as the amount of added soy powder (Gochujang) increased, the Salad dressing of the glossy, sour flavor, sour taste, and oily level decreased tendency (p<0.001). The results of an acceptance test showed that a 15% content of the soy powder (Gochujang)showed the greatest acceptance values in categories such as appearance, taste, texture, and overall acceptability. Therefore, when making a salad dressing with Gochujang, it is appropriate to add a 15% content of Gochujang to improve the quality and sensory characteristics of the salad dressing.

In this paper, we analysed vessel traffic volume and patterns of traffic flow for ships using areas where included wind farm site and adjacent waters of Daejeong Offshore Wind Farm, and estimated traffic volume by classified navigational routes according to suggestion of rational routeing measures on the basis of classified patterns after installation of offshore wind facilities. Also, we assessed vessel traffic safety for each designed routeing measures on the basis of estimated traffic volume and proposed requisite countermeasures for the safe navigation of ships. With a result of analysing patterns of traffic flow, the current traffic flow was classified by 8 patterns and the annual traffic volume was predicted to 8,975 ships. On the basis of these, expected the vessel traffic volume according to designed four routeing mesaures after installation of wind farm. As result of assessing vessel traffic safety by using powered-vessel collision model of SSPA on the basis of the estimated traffic volume, the value of collision probability was less than safe criteria $10^{-4}$. Thereby we made sure usability of the designed routeing measures for the safe navigation of ships.

This study describes the semantic theoretic interpretation through the extensive use of semantic metaphors for intensive web interface with information and the metaphoric value of metaphors for interface design. Common factors that influence web design are empirical establishment and verification for generating web symbols and these are have important elemental perspectives that are used to assess the usefulness and key elements of the site. In addition, the structure of the screen has begun to change dynamically from the application of web technological functions, and the media functions have become important to make web standards when implementing visual structuring from the perspective of semiotic. Instead of using a technical expression approach to examine semiotic, a semiotic approach is applied to create aesthetic codes through the human-computer interface in terms of semiotic in a variety of natural and universal fields. Based on this, it is used as means of communication to convey the intended meaning to users so as to highlight the importance of the usability issues and metaphors user interface.

Recently the 3D modeling techniques were developed rapidly due to rapid development of computer vision, computer graphics with the excellent performance of hardware. With the advent of a variety of 3D contents, 3D modeling technology becomes more in demand and it's quality is increased. 3D face models can be applied widely to such contents with high usability. In this paper, a 3D face modeling is attempted from a given single 2D frontal face image. To achieve the goal, we thereafter the feature points using AAM are extracted from the input frontal face image. With the extracted feature points we deform the 3D general model by 2-pass mesh warping, and also the depth extraction based on intensity values is attempted to. Throughout those processes, a universal 3D face modeling method with less expense and less restrictions to application environment was implemented and it's validity was shown through experiments.

The purpose of this study is to estimate the appropriate Demand Responsive Transport (DRT) fare for bus users upon introduction of the system, which is to improve ridership on economically non-profitable routes and to conform to the mobility right of those living in presently non-serviced rural areas. For this, a stated preference (SP) survey was adopted to assess respondents' preferences regarding DRT introduction, while the contingent valuation method (CVM) was used to calculate their willingness to pay (WTP) for DRT services. The analysis results show that, compared to the existing bus services with a 1,000 won bus fare, the value of DRT is considered to be 38.85%, 31.03% and 30.12% higher in terms of overall assessment, usability and convenience, respectively. The results of this study are expected to facilitate the decision making aimed at setting the appropriate DRT fare and implementing a DRT system that meets sustainability requirements.

A pure project finance is exposed to high default risk because it is made solely based on the business value of the project. Project finance with sinking funds can reduce the high default risk, in that it uses sinking funds to ensure the principal without requiring collaterals or guarantees. In view of economic efficiency, this paper analytically compares project finance with sinking funds to usual project finance and derives the condition for its superiority in corporate tax saving. Because sinking funds generate the repayments for the principal with compounding interest rates, in terms of effectiveness, project finance with sinking funds is suitable for long-term projects whose period is longer than 10 years. Pension funds can be good sources for project finance with sinking funds, since they should be managed to ensure stable investment returns for long periods.

In modern society, with the changing lifestyle, demand for complex cultural spaces is rising and various cultural spaces are emerging. However, user-centered cultural space research has not yet been shown. In order to find out whether various cultural experience functions and user experience types of complex cultural spaces are being delivered properly, this study compared and analyzed the representative cultural spaces of Korea, 'Starfield Library' and 'ARC.N.BOOK'. User experience analysis tools and individual in-depth interviews were used as research methods. As a result, both spaces responded that commercial space and brand library were out of harmony and that the use of services in complex cultural spaces was inconvenient. This is interpreted as the result of the need for improvement measures in the value and usability of experience provided by the current complex cultural space and is expected to help develop the complex cultural space in the future.

The convergence of various industries has removed the boundaries of software application fields and reduced the restrictions on convergence fields. Software requirements are diversified and they want to reconfigure software requirements in a fast cycle. Since various changes in requirements have to be accepted technically, research on methodologies and standards to increase the efficiency of software productivity and methods for standardizing and producing software are needed. In this study, we studied how the reusability and complexity of the software asset reconfiguration system appeared according to the developer's characteristics and environment to utilize the assets optimized in previous studies. At this time, we measured how the change in complexity according to the usability and asset composition method that appears according to the developer's characteristics appears, but there is a limit to the collected data, so it is necessary to secure the quality of the measured value through continuous data collection. In addition, an intelligent system application plan is needed to supplement the problem of context classification in the use stage of complex assets.

This study aims to investigate the influence of emotional engineering factors on brand preference and loyalty in smartphone product design. The emotional engineering factor was divided into color, performance, usability, value, and reliability, and the relationship between brand preference and loyalty was empirically analyzed. As a result of the analysis, the emotional engineering factor in the smartphone product design has a positive effect on the brand preference, and the factors having the greatest influence are the performance and color factors. In smartphone product design, the emotional engineering factor has a static effect on loyalty, and the factors that have the greatest influence are reliability and performance factors. The higher the brand preference in product design, the greater the affect on loyalty. It is necessary to approach product design that fits the characteristics of consumers by identifying the influential factors among the product design emotional engineering factors.
