Although lisdexamfetamine is used as a recreational drug, little research exists regarding its potential for dependence or its precise mechanisms of action. This study aims to evaluate the psychoactivity and dependence profile of lisdexamfetamine using conditioned place preference and self-administration paradigms in rodents. Additionally, biochemical techniques are used to assess alterations in the dopamine levels in striatal synaptosomes following administration of lisdexamfetamine. Lisdexamfetamine increased both conditioned place preference and self-administration. Moreover, after administration of the lisdexamfetamine, dopamine levels in the striatal synaptosomes were significantly increased. Although some modifications should be made to the analytical methods, performing high performance liquid chromatography studies on synaptosomes can aid in predicting dependence liability when studying new psychoactive substances in the future. Collectively, lisdexamfetamine has potential for dependence possible via dopaminergic pathway.

Previous research for visual assessment of streetscape employed static simulation methods to represent future landscape. However, streetscape is experienced sequentially, and thus dynamic simulations can be more effective. This study tried to adopt computer animation in the evaluation of streetscape, and examined its effects and possibilities. Three development scenarios for the redevelopment districts of Sokong-Ro and Banpo-Ro in Seoul were designed, and simulations were produced by three methods-photo-retouching, computer still image, and animation. A preference questionnaire was asked to 69 university students, and the effects of simulation methods on visual preference were examined. In addition, the frames of the animation were reclassed to identify the visibility of physical elements. The relationships between the visibility and visual preference were analyzed. The results showed that visual preference can be explained by three factors-Amenity, Tidiness, and Variousness-that account for 62.4% of the total variance, and the Amenity showed the highest proportion: 36.0%. Among the three simulation methods, animation showed the largest difference in preference for the most important factor(Amenity), and yielded the highest correlation between visibility of physical elements and Amenity. This result demonstrated that dynamic simulations can provide more accurate observation of visual changes, especially because the simulated landscape is experienced sequentially. The results also revealed that the sequential change in the visibility of physical elements can be examined easily and precisely by animation. This benefit of animation enables analysts to identify the points where the landscape varies the most, and thus visual preference should be evaluated.

In this study, the color value, water solubility, swelling power and sensory evaluation of Dioscorea batatas was examined with the addition of functional additives such as sugar alcohols and organic acids to investigate the browning inhibition and preference of these additives. Treatment with erythritol and citric acid were found to result in the highest hunter L-value, solubility and swelling power relative to the other functional additives. Therefore, erythritol and citric acid were selected as additives for Dioscorea batatas. The Dioscorea batatas containing the mixed additives (erythritol and citric acid) showed higher brightness, water solubility and swelling power than those containing only a single additive. In addition, the color and taste preference determined in the sensory evaluation had higher values when the mixed additives were used.

The purpose of this thesis is to suggest basic objective data for landscape planning and design through the quantitative analysis of the visual impact of pavilion situated in natural landscapes. For this, naturality and visual preference scores of landscape s1ides were measured by questionnaires, visual volumes of pavilion in the natural landscape were evaluated using the Mesh analysis and images structure was analyzed by the factor analysis algorithm The results of this thesis can be summarized as follow. Landscape slides No. 27 and 9 were ranked more highly for naturality, and slides No.22, 28, 6 and 4 were ranked more highly for visual preference. Factors covering the spatial image of the natural landscape were found to be the evaluation, the tidiness and the space volume. By using the control method for the number of factors, T. V., were obtained as 59.0%. For all experimental landscape slides, the factors of evaluation and tidiness were found to be the main factors determining the naturality and visual preference. The naturality and actor scores and the visual preference and factor scores were found to exepress the regression relation.

One of the most important aspects to succeed in character industry is to develop a character that it can sensibly satisfy customers. For this, sensibility evaluation has to be carried character design have to be analyzed, firstly. In this study, sensibility evaluation using multi-variate analysis was performed for some humanized characters. From the factor analysis, sensibility factors were extracted and sensibility characteristics for characters were analyzed by those factors. Preference for those characters was evaluated and was analyzed in relation to those sensibility characteristics. Finally, a direction of character design was proposed from those results.

This paper reviews and examines the empirical results of past research concerning individual differences and similarities in landscape preference and evaluation. The conflicting results (differences and similarities) found in the review are attributed to the variety of methodology adopted by the past research and to the lack of comprehensive theoretical base in the field of landscape research. Two suggestions are derived from the review. First, both the landscape type to be evaluated and the measurement context to be used by research subjects have critical importance in results. Thus, it is suggested that researchers should be careful in selecting landscape type and measurement tool. Second, more scholartic endeavours should be put into a development of comprehensive theory of landscape experience that could explain both differences and similarities in people's landscape preference and evaluation. Once developed, the theory would not only provide us more valid and specific research methodology, but also allow us to design more healthy and valued landscape.

The purpose of this study is to identify consumer needs and sensory evaluation of jacquard fabrics for blind using low melting polyester. Ten kinds of jacquard fabric used for this study were developed. Developed jacquard fabrics were assessed subjectively by 164 consumers using 7-point scale of 22 consumer needs and 43 sensory descriptors. The results were briefly summarized as follows: the most important parameter to choose fabric for blind was 'Easy-use' and the other parameters are 'Lightproof', 'UV-protect', 'Design', 'Price', 'Color', 'Insulation', 'Easy-care'. The image sensibility of jacquard fabrics was explained by six factors: feminine, active, modern, traditional, pure, cozy. Higher preference was found in jacquard fabrics of clear, natural, luxurious, simple, feminine, young, cozy, graceful image. The preference was predicted 38.2% with feminine, modern, pure, cozy, traditional factors. Correlation coefficient between image sensibility factor 1 and preference was 0.437. The 3 factors (feminine, modern, pure)were selected as significant image sensibility affecting preference.

Keeping abreast with the latest consumer's trends, industries are focusing on sensibility aspects of products to meet consumer's needs. The car(?) seat cover fabrics are more closely related to human senses than anything else. This study attempted to investigate which seat cover fabric can give good feeling to consumers and to analyze their characteristics. Twelve kinds of jacquard fabric used for seat cover were selected. The Kawabata Evaluation System was used to measure the mechanical properties of 12 jacquard fabrics, and tactile sensibility(TS), and preference(P) determined by subjective evaluation of 160 participants were also utilized. The stepwise regression analysis was made to select the most significant mechanical properties, and some models for predicting tactile sensibility and preference was developed. The results are briefly summarized as follows: the most important parameter to choose seat cover fabric is a "hygienic property" and the other parameters are 'materials with color fastness', 'compressive property', 'color', 'antibacterial property', 'easy-care property'. The LogSMD, LogB, LC, EM were selected as significant mechanical properties affecting tactile sensibility. Also, the LC, LogB, LogSMD, LogWC, LogMMD were selected as significant mechanical properties affecting preference.
