There is a growing need for technology transactions between the technology providers, who develop technologies, and the technology consumers, who purchase and commercialize technologies, to be smooth, when technologies, as intangible assets, are traded as items that can be purchased and sold. In response to these challenges, this study examines new approaches to assessing the fair market value of technologies. Because corporations are the main force behind technology development and commercialization in the existing business environment, applying one valuation method to technology assets is viable; however, as the subjects of technology development and technology commercialization are separate, the need for price negotiations between the subjects of technology transaction has grown. Moreover, as the investigations into and the application of transaction prices have been performed separately by technology providers, technology consumers, and technology assessment financial institutions, the research on technology valuation methods has shown that there are differences in perceived transaction prices between the subjects involved. This research presents a new method, appropriate to technology transactions; unlike existing methods, it grants option values to the technology provider and newly defined key variables to the technology consumer.

Increasing affectability of high-speed Internet and convenient access devices has made the Internet a major source of information search and sharing. As the provision of information has rapidly becomes an important and viable business model, the objective utility and marketability of information contents have become a focus of interest among many academicians and managers. Researchers have traditionally focused on the design of the interface, availability of resources, network accessibility, the format of web sites and their underlying systems. However, the usefulness of contents has been left as a little explored issue. To correctly diagnose and pursue the viability of contents provision business a shift of perspective is required : a shift from technology-oriented perspective toward user-oriented perspective, and a shift from form and design focus toward content focus. This research attempted to analyze consumer-oriented information quality in a more systematic way by focusing on a limited domain travel-related information contents. We proposed a relationship among consumers'behavior, characteristics of information, and the values of information measured by users. An empirical examination of the model was performed using a survey on Internet users in Korea. Implications are drawn for managers responsible for creating marketable contents.

The author collected and compared midsagittal, coronal, coronal oblique, and transversal images of Korean monophthongs /a, i, e, o, u, i, v/ produced by a healthy male speaker using 1.5 T MR, VISION. Area was measured by computer software after tracing the cross-section at different points along the tract. Results showed that the width of the oral and pharyngeal cavities varied compensatorily from each other on the midsagittal dimension. Formant frequency values estimated from the area functions of the seven vowels showed a strong correlation (r=0.978) with those analyzed from the spoken vowels. Moreover, almost all of 35 students who listened to the synthesized vowels from area data perceived the synthesized vowels as equivalent to the spoken ones. Movement of constriction points of vowel /u/ with wider lip opening sounded /i/ and led to slight changes in vowel quality. Jaw and tongue movement led to major volume variation with an anatomical limitation. Each comer vowel varied systematically from a somewhat constant volume of the average area. Thus, the author proposed that any simulation studies related to vocal tract area variation should reflect its constant volume. The results may be helpful to verify exact measurement of the vocal tract area through vowel synthesis and a simulation study before having any operation of the vocal tract.

The purpose of this study is to propose and test a model of customer retention in Internet shopping malls when switching barriers and comprehensive customer value exist in terms of economic and experiential aspects. The literature about customer retention propose that switching barriers are important factors other than satisfaction influencing customers' intention to remain with a specific supplier. The switching barriers mean anything that makes customers' defection difficult or costly and are consisted of perceived switching costs, attractiveness of alternatives and virtual relationships. The Customer Value Scale by Mathwick(2001) is applied to this study as economic value, shopping efficiency, service excellence, aesthetic appeal and playfulness(Zeithaml, 1988; Holbrook, 1994). The analyses showed partial support for the affirmative effect of customer values and switching costs and full support for the affirmative Influence of satisfaction on repurchase intention in the Internet shopping mall environment. But the attractiveness of alternatives and virtual relationship did not have a significant Influence like the result of Jones(1998)'s study of the service industry.

Drawing on the theoretical framework of customer value-satisfaction-loyalty, this study examines how scarcity message influences customers' value, satisfaction, and loyalty in the context of group-buying social commerce. Previous studies have argued that scarcity message limiting the avilability of products and service is a source of enhancing customer value. In this regard, this study posits scarcity message as a predictor of customer value. Furthermore, this study classifies customer value into two forms (i.e., utilitarian value and hedonic value) and verfies how scarcity message is associated with them. To test the proposed research model and hypotheses, this study performed structural equation modeling (SEM) analyses, using a total of 292 data collected on users who have experience in purchasing products and service through group-buying social commerce sites such as Coupang, Timon, and WeMakePrice. The key results are as follows : First, scarcity message increases utilitarian and hedonic values and further customer satisfaction. Second, utilitarian value increases customer satisfaction and repurchase intention while hedonic value has nothing to do with them. The findings imply that customers seek to maximize utilitarian value through group-buying social commerce. Finally, this study indicates that repuchase intention depends greatly on customer satisfaction.

This study was conducted to examine the physicochemical properties and consumer acceptability of commercial Gang-jeong. The samples used in this study were nine different Gang-jeong as commercial products. To accomplish this research, the physicochemical properties of nine samples, including moisture, crude lipid, sugar contents, acid value, color values, and texture, were measured. In addition, consumer panels evaluated the overall acceptability, appearance, flavor, sweetness, and texture of samples using a 9-point Likert type scale as well as the perceived intensities of sweetness and rancid odor by a 9-point Just-About-Right (JAR) scale. All data were statistically analyzed using One-way ANOVA, Principle Component Analysis, Hierarchical Cluster Analysis, and Pearson's Correlation Analysis. All physicochemical properties were significantly different among the samples (p<0.001). Analyses of consumer acceptability and JAR ratings of the nine samples showed significant differences (p<0.001).

The purpose of this study was to investigate the influence of luxury brand value on luxury brand preferences according to chemyon(social-face). For data collection, research questionnaires were responded by 222 females over 20 years old consumers living in Pusan and Ulsan. The collected data were analyzed using SPSS 14.0 for windows Package by frequency analysis, the factor analysis using Varimax, reliability analysis, multi-regression analysis, and chow-test. The results of this study were as follows: First, concerning the worth of luxury brands that qualify value, conspicuous value, unique value, and emotional value significantly affected the consumers' luxury brand preferences. On the other hand, only social value of the luxury brand did not have a significant effect on the consumers luxury brand preferences. Second, the study was to investigate whether the luxury brand value has an effect on the brand preferences according the consumer's chemyon or not. The results showed different effects of perceived values on luxury brand preferences between the low chemyon group and the high chemyon group. The high chemyon group had an effect on conspicuous value, social value, and emotional value, while the low chemyon group had an effect on quality value for luxury brand preference.

In health promotion program, the fear of gaining weight is often given as a reason for giving up smoking cessation by the participants. The purpose of this study is to compare drinking habit, exercise and BMI distribution according to smoking habits. The subjects of this study were 83 industrial workers in Gu-mi. Data collection was conducted from Sep. 18th to Sep. 24th 2000. The method was self-reported questionnaire survey, consisted of general characterisics, smoking habits and its relevant questions. The results are as follows : 1. Fifty-nine percents of the subjects were currently smoking. 2. Smoking habits were significantly related with drinking(p=.049). More smokers(81.6%) reported drinking habit than non-smokers(61.7%). 3. Forty-one point two percents of the non-smoker and 34.7% of the smoker perceived their body type as "fat". 4. The mean values of BMI were 22.0 in smokers with 1-9 cigarettes/day, 24.2 in 10-19 cigarettes/day smokers and 24.0 in smokers with over 20 cigarettes/day. There are no statistically significant differences in BMI among smoking habits. 5. BMI among different smoking habit groups was not significant different in age, drinking habit, exercise, and smoking habit.

This study investigated whether listeners' perceptual patterns varied according to base token selected for stimuli manipulation. Voice onset time (VOT) and fundamental frequency (F0) values were orthogonally manipulated, each in seven steps, using naturally produced words that contained a lenis (/kan/) and an aspirated (/k^han/) stop in Seoul Korean. Both native and non-native groups showed significantly higher numbers of aspirated responses for the stimuli constructed with /k^han/, evidencing the use of minor cues left in the stimuli after manipulation. For the native group the use of the VOT and F0 cues in the stop categorization did not differ depending on whether the base token included the lenis or aspirated stop, indicating that the results of previous studies remain tenable that investigated the relative importance of the acoustic cues in the native listener perception of the Korean stop contrasts by using one base token for manipulating perceptual stimuli. For the non-native group, the use patterns of the F0 cue differed as a function of base token selected. Some findings indicated that listeners used alternative cues to identify the stop contrast when major cues sound ambiguous. The use of the manipulated VOT and F0 cues by the non-native group was not native-like, suggesting that non-native listeners may have perceived the minor cues as stable in the context of the manipulated cue combinations.

Two new impulsive driving technologies for 120Hz liquid crystal display (LCD) panels are proposed to improve moving picture quality. One technology generates the dark frame using an adder and a shifter simply without using any look up tables (LUTs). It results in a cost effective impulsive scheme with motion picture quality comparable to that of high speed driving. The other is a backlight flashing method designed to avoid ghost images. The issue of ghost images caused by the slow response time of liquid crystal (LC) is solved by means of 120Hz overdriving and 120Hz backlight flashing. Using the perceived blur edge time (PBET) metric, measured moving picture response time (MPRT) values were 10.8ms and 4.4ms, respectively, while that of 120Hz high speed driving was 10.1ms.
