The purpose of this study is to review the concept of virtuality and analyze in which way virtuality is expressed in fashion. As for the research methodology, literary research was undertaken to study psychoanalytical and socioeconomic contexts in which virtuality has been formed. In addition, demonstrative studies on styles were undertaken through the analysis of photos in modern fashion magazine. With the explosive diffusion of the Internet since the 1990s, people have created a new identity in cyber space. Indeed, computers have made it possible for human beings to make virtual bodies in any way they want. Through the experiment of creating the figures that they dreamed of in their childhood buy could not embody in their actual life, people are making up for their narcissistic ego of their childhood. With the advent of the cyber society, dreams have been realized in cyber space, which in turn has influenced reality and finally had an effect on fashion. In cyber space, People try to break away from their bodies by combining elements of a different nature from them. They are dying hair and skin, and using holographic fabric for fashion, metallic color and geometric pattern for cosmetics. In pursuit of omnipotent beings, people have depicted models as flying in a weightless state and floating in the water within dress of undefined silhouette, so that they can be shown as transcending the law of nature. Furthermore, a variety of cultures newly appearing as dominant in cyber space have constantly interacted with actual life and formed an collage of heterogeneous cultures in fashion.

This study examined the different meal duration expectations and dining characteristics of customers each stage of service (order, cook, check), and investigated the impact of perceived meal duration on customers' satisfaction. The procedures consisted of four phases. During the first phase, the different meal duration expectations and dining characteristics of customers of an Italian restaurant in Seoul were examined by survey at each stage of service. The second phase investigated the impact of perceived meal duration on customer' satisfaction. The third phase compared perceived meal duration and actual meal duration. The last phase suggested appropriate meal duration for maximization of customer' satisfaction. We also examined the effects of meal time (lunch or dinner) on meal duration preferences. Customer satisfaction was decreased with longer perceived meal duration for the order and check stages and too short perceived meal duration for the cook stage. To determine appropriate meal duration for each service stage, the relationship between perceived and actual meal durations was examined. This study confirms that customers dining at restaurants preferred a longer cook time and that a shorter meal duration at dinner decreased satisfaction ratings more when compared to lunch.

This study looks into the relationship between mother's nutrition knowledge and the actual situation of snacks consumption by mothers living in Daegu and Gyeongbuk. The data were analyzed by statistical methods such as frequency, percentage, Chi-square, ANOVA and Duncan with the SPSS Windows 19.0 program. Regarding level of education, most of the subjects in the 'High' and 'Medium' Groups were university graduates, whereas most of those in the 'Low' Group were college graduates. Most of the subjects ate used processed snacks, produced snacks, or cooked snacks themselves, and most added fruits, followed by milk products and confectionery as snacks. Most of the subjects were satisfied with their experiences of purchasing snacks for children. In selecting the snacks, most of them attached importance to 'balanced nutrition', followed by 'food additives', 'allergy', and 'sanitation.' These results show that nutrition education is necessary for choosing correct and good quality snacks for children.

This study was carried out to explore the actual condition of family-friendly education of corporations and organizations supporting them for the purpose of activating the family-friendly certification system. The researches on the family-friendly education of corporations or related organizations have not become an object of attention, although the policies of family-friendly corporations have been the major concern of researchers who have conducted studies on the balancing between work and family. For the first time, this study investigated the family-friendly education programs of corporations and organizations supporting them. In addition to this work, interviews with laborers were performed to learn the actual participation in the education. The results showed that even corporations selected as excellent corporations by the government scarcely provided family-friendly educations and few laborers participated in them. The most educations provided by corporations were for the improvement of work ability or job training. Education for family concentrated only on the role of the father. The focus of educations supporting corporations was biased to the view of corporation or family, not balanced between the two. So it was suggested that researchers should pay attention to developing diverse education programs encompassing the whole stages of life cycle and the balancing between corporation and family.

This study was conducted to investigate the actual state of utilization of Korean traditional foods by Korean Americans residing in L.A. area and to provide come policies, to improve their attitudes for Korean traditional foods. The proper period preparing traditional foods was the occasion of family events(47.0% )and Korean festivals(40.8%). Festival foods were prepared in Sulnal( =New Year's Day), Chusok( =the Korean Thanksgiving Day), Daeborum( =the 15th of January by the lunar calendar), Dongji( =the winter solstice) and Tano( =the 5th day of the 5th by lunar month), respectively. Sixty five percent of all the respondents expressed their wish to hand down the cooking methods of traditional foods. However, only28.6% of the respondents at their twenties replied positively on this matter. To maintain and develop traditional foods abroad, it is necessary that older generations sometimes offer opportunities to meet with them to the coming korean generations to taste traditional foods and that Korean food companies establish special selling agencies abroad and export standardized traditional foods. And furthermore, if tourism corporations and cooking schools hold a food exhibition and or a food-tasting party, occasionally, in conjunction with the embassies and legations abroad, the utilization of traditional foods will increase.

This study was executed to find the applicability of press drying of tree disk by investigating the shrinkage and drying defect and to form appropriate model by comparing the actual moisture content(MC) and internal temperature in respect of drying time with calculated values based computer simulation to which was applied finite difference method. In press drying disk, heating period, constant drying rate period maintained plateau temperature at 100$^{\circ}C$ and falling drying rate period were significantly distinguished. Actual MC and internal temperature were analogous to those calculated at comparing points. Heat transfer model formed by Fourier's law using specific heat of moist wood and conduction coefficient considering fractional volume of each element of wood cell wall, bound water, free water and air showed applicability as basic data to developing heat expansion, shrinkage and drying stress during press drying. Also mass transfer model formed by Fick's diffusion law using water vapor diffusion coefficient showed applicability. Longitudinal shrinkage was developed by pressure of hot press and tangential shrinkage was restrained by hygrothermal recovery. The heart check, surface check and ring failure were occurred differently in species, but V-shaped crack didn't develop.

During the casting process, it is possible to minimize shrinkage and blowholes by modifying the casting design. However, it is impossible to eliminate these factors completely. Therefore, mechanical design engineers apply a sufficient safety factor owing to the possibility of insufficient performances of the cast products. In this paper, prediction method of the fatigue life of cast products containing shrinkage is conducted by using CT (computed tomography) and the SSM (shape simplification method), and additional fatigue analyses are carried out. The analysis results are then compared to results from actual experiments on samples with shrinkage defects. It is found to be that the considering actual shrinkage in cast products by means of stress and fatigue analyses is more accurate and effective. It is also considered that the proposed hot spot method provides us a good tool to predict the fatigue lifes of cast product.

Financial risks associated with capital investments are often measured with different feasibility indicators such as the net present value (NPV), the internal rate of return (IRR), the payback period (PBP), and the benefit-cost ratio (BCR). This paper aims at demonstrating practical applications of probabilistic feasibility analysis techniques for an integrated feasibility evaluation of the IRR and PBP. The IRR and PBP are concurrently analyzed in order to measure the profitability and liquidity, respectively, of a cash flow. The cash flow data of a real wind turbine project is used in the study. The presented approach consists of two phases. First, two newly reported analysis techniques are used to carry out a series of what-if analyses for the IRR and PBP. Second, the relationship between the IRR and PBP is identified using Monte Carlo simulation. The results demonstrate that the integrated feasibility evaluation of stochastic cash flows becomes a more viable option with the aide of newly developed probabilistic analysis techniques. It is also shown that the relationship between the IRR and PBP for the wind turbine project can be used as a predictive model for the actual IRR at the end of the service life based on the actual PBP of the project early in the service life.

Steam turbine rotors are the most critical and highly stressed components of a steam power plant; therefore, the life expectancy of the turbine rotor is an important consideration for the safety of a steam power plant. The objective of this paper is to develop a life estimation program for turbine rotors for all possible operating conditions. For this purpose, finite element analysis was carried out for four normal operating modes (cold, warm, hot and very hot starts) using ABAQUS codes. The results are made into databases to evaluate the life expenditure for an actual operating condition. For any other possible abnormal operating condition, the operating data are transmitted to the server (workstation) through a network to carry out finite element analysis. Damage estimation is carried out by transmitting the finite element analysis results to the personal computer, and then the life expectancy is calculated.
