It is hot issue to get the competitiveness of product through reliability-growth as well as availability and safety in almost high-technology industry including military, chemistry, nuclear, telecommunication, transportation service and so on. In advanced countries, they experienced remarkable growth based on reliability technology in materials&parts industry as well as high-tech industry. It has become a symbol of national competitiveness and created a higher value added. This paper is taking on effectively developing ways to deploy IEC 60300 dependability management system and the base technology that are needed to improve competitiveness of industries in Korea.

This study was conducted to investigate consumer behavior and perception related to alcoholic beverages and Korean rice wines (yakju). Self-administered questionnaires were collected from 254 male and female adults in the Gyunggi-area of Korea. Male respondents were significantly more likely to drink more often, consume greater amounts and spend more on alcoholic beverages. Male respondents preferred, in order, soju, beer and wine. Female respondents preferred, in order, beer, wine and soju. Most of the respondents (69.2%) showed conservative consumption behaviors, and indicated they would drink a new product when it became popular. Flavor/taste was the most important attribute when selecting alcoholic beverages. The reasons for drinking yakju were "high quality" and "considering health". The most answered reason for low market share of yakju was lack of publicity and marketing.

The incomplete saturation and the void formation during the resin infiltration into fibrous porous media in the resin transfer molding process cause failure in the final product during its service. In order to better understand flow behavior during the filling process, a finite-element scheme for transient flow simulation across the micro-structured fibrous media is developed in the present work. A volume-of- fluid (VOF) method has been incorporated in the Eulerian frame to capture the evolution of flow front and the vertical periodic boundary condition has been combined to avoid unwanted wall effect. In the microscale simulation, we investigated the transient filling process in various fiber structures and discussed the mechanism leading to the flow fingering in the case of random fiber distribution. Effects of the filling pressure, the shear-thinning behavior of fluid and the volume fraction on the flow front have been investigated for both intra-tow and the inter-tow flows in dual-scale fiber tow models.

Competitiveness strategies has been associated in the tourism literature as a crucial factor for the success of tourist. The study aims to explore the competitiveness strategies for tourism destinations by conducting in-depth interviews with probe questions. Thirteen community enterprises' managers in rural tourism communities were interviewed with a semi-structured interview questionnaire for one or two hours. From the interview data, eight themes in two dimensions were identified as competitiveness strategies of rural community enterprises in rural Korea. Differentiation strategies consist of new product development, service improvement, brand image improvement, advertise and public relation, and concentration. Cost leadership dimension includes cost reduction, increasing benefit, and long-term investment. The findings of this paper implicate the underlying the competitiveness strategies from managers' perspective.

This study investigated the rheological and sensory characteristics of pickle with frozen pine mushroom. P3(Developed pickle seasoning) was the best by preference among three kinds of pine mushroom pickle seasoning. For flavor and functionality, pine mushroom pickle was processed by using three kinds of method(P3-1: P3+cinnamon 10 g, P3-2: P3+licorice 10 g and P3-3: P3+licorice 5 g+cinnamon 5 g). As a result, the product from P3-3(P3+licorice 5 g+cinnamon 5 g) was the best preferred pine mushroom pickle. The pH value of P3-3 was 2.15, 42.9 degrees Brix, and its color value was L(54.65), a(-1.61), b(17.87). Its texture level was higher than that of other products, but it would be lowered on storage. Until the 28th day of storage, microorganisms in pine mushroom pickle seasoning were detected less than 30 CFU/mL.

The purpose of this study is to investigate the preference of Korean traditional food and kimchi among different age groups in order to find a way to increase kimchi consumption. For this study, data from 15 male respondents(5.2%) and 271 female respondents(94.8%) was used. Age distribution of total respondents were in their 20's(21.8%), 30's(32.7%), 40's(32.7%) and 50's(11.6%), which showed the rate of 40's was very high. Most of the groups showed similar rates over the question on "have to eat kimchi" and "don't need to eat kimchi", but the elders' preference was high while the youngers' was relatively low. Therefore, the preference of kimchi has a small gap between the age groups, but all of them like kimchi in general.

This study was intended to suggest overseas expansion strategy of Korean fashion character through sensitive space creation. This study reviewed literature, and did internet searching and observation. For the research methods were the analysis of the main retail spaces utilizing character and case study for the classification of collaboration types between retail space and character. As a results, 8 collaboration types between space and character were extracted: collaboration between retail distribution space and character, collaboration between product space and character, collaboration between service space and character, collaboration between experience space and character, collaboration between moving space and character, collaboration between publicity & advertising space and character, and collaboration between exhibition space and character. This study suggested the necessity of consistent identity strategy between character and retail space for a new character brand and the effectiveness of collaboration strategy for enhancement of character brand awareness.

Using composite materials for the carbody of tilting train has many advantages such as manufacturing variety, specific high-strength ＆ stiffness characteristics, and long-life durability, but the strongest advantage could be the possibility of lightweight product. In the leading countries, the composite materials are used for the material fur drivers'cabs, interior/exterior equipments for railway train, and it is now developing the composite materials applied for the train carbody structure. In this paper, we conducted the evaluation of structural stability for the aluminum and composite carbody of the Korean Tilting Train express(TTX) with the service speed of 180km/h.

Since the focus of QFD is placed on the early stage of product development, the uncertainty in the input information of QFD is inevitable. If the uncertainty is neglected, the QFD analysis results can be misleading. This paper proposes an extended version of the QFD methodology, called Robust QFD, which is capable of considering the uncertainty of the input information and the resulting variability of the output. The proposed framework aims to model, analyze, and dampen the effects of the uncertainty and variability in a systematic manner. The proposed framework is demonstrated through a case study on the ADSL-based high-speed internet service.
