This study is intended to analyse the economic sensitivity of imported fishery products due to decrease in or elimination of tariff rates through the progress of free trade. Forty-seven species of fishes were selected for this study on the basis of the HS Code. The substitution and price effects were calculated using the price elasticities of both domestic and imported demands for fishery products under the assumption of 5% decrease in a tariff rate. Seven main economic variables were extracted from the fishery industry which can mediate the substitution and price effects. A multiple regression analysis was conducted to obtain the influence weights of these main economic variables on both effects. The order of sensitivity of the fishes was calculated using these weights. The 47 fish species were classified into four groups according to their sensitivity based on the means and the standard deviations of their total scores on seven main economic considerations. Nine fish species such as squids, hair tails, shellfishes, and crabs belonged to the hyper-sensitive group, whereas 15 fishes such as eels, sea breams, and sea weeds belonged to the sensitive group. Twelve species including common sea basses, cods, and abalones were among the less-sensitive group, and 11 species including skate rays and mud fishes comprised the non-sensitive group.

With the development of the auto industry, the automobile manufacturers demand to shorten development period and reduce the cost. Compared with the traditional method, applying the virtual prototype is more economical. This paper presents a method for parameters sensitivity analysis and optimizing the performance of vehicle noise and vibration. The existing design processes were repeatedly analyzed with a focus on vehicle performance to decide the design parameters of dimension, thickness, mounting type of body and chassis systems in the vehicle development period. This paper describes the prediction technique of vehicle performance using L18 orthogonal array layout, quality deviation analysis and parameter sensitivity analysis for robust design. This paper analyzed the performance correlation equation through the frequency and sensitivity database according to a design factor change. The new concept is that the performance prediction is possible without repeated activities of test and analysis. This paper described the parameter analysis applications such as bush dynamic stiffness and bush void direction of rear suspension. Design engineer could efficiently decide the design variable using parameter analysis database in early design stage. These improvements can reduce man hour and test development period as well as to achieve stable NVH performance.

Fiber industry is export leading industry that guide national economy development after the 1960s in Korea. But lately, including China and Southeast Asia pursuit, domestic fiber industry is taking serious situation. Various kind methods can be proposed for high value added in fiber industry, the research about color is essential. The importance of color is increasing in modern textile and fashion industry. Color is important factor of textile and fashion industry because color affects strong influence in human's sensitivity. Color expresses by hue, value and chroma but fashion industry is using mainly hue and tone color system. Daegu Gyeongbuk area is domestic maximum syntheic fiber producing district. This study planned the polyester standard color collections for general color management of the polyester industry in Daegu Gyeongbuk. As basic research for this I investigated the color appearance distribution of polyester fabrics in Daegu Gyeongbuk that were produced for the recently 10 years and Japanese polyester color collections "SCOTDIC 2450". Reflect these study finding, in this research planned the usable standard color collections "Hue and Tone Polyester Standard Color 288". This research constructs insufficient domestic color infrastructure and expect that basic role to develop the competitive power for Korean fiber industry.

This study examines the effects of collaboration type and brand sensitivity on consumer responses toward fashion collaboration brands. For this study, six brands of fashion collaboration were selected by collaboration types: collaboration with same industry (Uniqlo-Jill Sander, H&M-Sonia Rykiel, and Levis-Jean Paul Gaultier) and collaboration with different industries (LG-Prada, Samsung-Armani, and LG-Levis). A selfadministered questionnaire was developed based on the literature that mainly included brand sensitivity, consumer response (brand association, brand values, and purchase intention), and marketing strategic elements in the context of fashion collaboration. For collecting the data, respondents were asked to choose and assess a previously purchased brand. A total of 299 usable data responses were obtained from Korean consumers aged from 15 to 40 years old. The consumer response toward the fashion collaboration brand consisted of four factors: Emotional value, perceived quality, symbolic value, and brand association. The results showed that the collaboration type had the main effect on emotional value, symbolic value, and purchase intention. Brand sensitivity had the main effect on brand association, emotional value, symbolic value, and purchase intention. There was also an interaction effect on emotional value. With respect to strategic marketing elements, product differentiation, premium pricing, and value pricing had partially positive effect on consumer responses; however, promotion had a negative effect on consumer responses (e.g., perceived quality, and emotional value). In addition, collaboration type or brand sensitivity moderated the effect of strategic marketing elements on consumer responses. This study discussed a managerial implication to develop a strategic brand alliance to manage brand equity in the fashion marketplace.

Background: Animal skin provides an ideal medium for the propagation of microorganisms and it is used like raw material in the tannery and footware industry. The aim of this study was to evaluate and identify the microbial load in oropharyngeal mucosa of tannery employees. Methods: The health risk was estimated based on the identification of microorganisms found in the oropharyngeal mucosa samples. The study was conducted in a tanners group and a control group. Samples were taken from oropharyngeal mucosa and inoculated on plates with selective medium. In the samples, bacteria were identified by 16S ribosomal DNA analysis and the yeasts through a presumptive method. In addition, the sensitivity of these microorganisms to antibiotics/antifungals was evaluated. Results: The identified bacteria belonged to the families Enterobacteriaceae, Pseudomonadaceae, Neisseriaceae, Alcaligenaceae, Moraxellaceae, and Xanthomonadaceae, of which some species are considered as pathogenic or opportunistic microorganisms; these bacteria were not present in the control group. Forty-two percent of bacteria identified in the tanners group are correlated with respiratory diseases. Yeasts were also identified, including the following species: Candida glabrata, Candida tropicalis, Candida albicans, and Candida krusei. Regarding the sensitivity test of bacteria identified in the tanners group, 90% showed sensitivity to piperacillin/tazobactam, 87% showed sensitivity to ticarcillin/clavulanic acid, 74% showed sensitivity to ampicillin/sulbactam, and 58% showed sensitivity to amoxicillin/clavulanic acid. Conclusion: Several of the bacteria and yeast identified in the oropharyngeal mucosa of tanners have been correlated with infections in humans and have already been reported as airborne microorganisms in this working environment, representing a health risk for workers.

With use of (G)MR head, thermal asperity (TA) has been a big concern in drive industry. In this study, we investigated several factors of heads and disks which affects the TA sensitivity of the drive. TA experiments were conducted by introducing the particles on the drives using a particle injection chamber. It was found that the slider ABS shape can help to reduce TA or contamination in the head/media interface. However, TA sensitivity of the drive mainly depend on the intrinsic property of (G)MR sensor. GMR head is much less sensitive to TA compared with MR head. However, in case that the same bias current was applied for both of MR and GMR head, TA sensitivity of GMR head became almost identical to that of MR head. Therefore it was found that the bias current is a dominant factor in determining TA sensitivity of the head. TA sensitivity of different types of disks was also studied. The scratch resistance of the carbon overcoat layer is the one of the main factors which influence TA rejection capability of the disks.
