Sustainability has been a important issue in fashion industry that reflects the modern phase of the time. More education institutions than ever before are beginning to offer specialized courses, certificates and degrees related to sustainability in fashion, and many fashion institutions are working to embed sustainability issues into the educational contents. In this study, I investigate how sustainability is being integrated into the curriculum of leading fashion institutions, corporate management activity across the world and overview the world leading educational programmes related to sustainable fashion, pulling out the unique expertise and areas of specialization for each institution. In conclusion, the sustainable fashion were still not widely promoted domestical fashion institutions compare with other foreign leading fashion institutions. This happens in fashion business as well. Korean fashion institutions have to make educational program and certificates and degrees related to sustainability because the educational program can transform domestic fashion industry to sustainable fashion leading country level.

Forecasting of short-term employment fluctuations provides a useful tool for policy makers in risk managing the labor market. Following the process of producing the composite leading indicator for macro economy, the paper develops the employment leading indicator(ELI) for the purpose of short-term forecasting non-farm payroll employment in private sectors. ELI focuses on early detecting the point of time and the speed in phase change of employment level.

A computational study was carried out in order to investigate aerodynamic characteristics on leading edge sweepback angles of Flying-Wing configurations. The viscous-compressible Navire-Stokes equation and Spalart-Allmaras turbulence model of the commercial CFD code were adopted for this computation analysis. This investigation examined aerodynamic characteristics of three different types of leading edge sweepback angles: $30^{\circ}C,\;35^{\circ}C\;and\;40^{\circ}C$. The freestream Mach number was M=0.80 and the angle of attack ranged from ${\alpha}=0^{\circ}C\;to\;{\alpha}=20^{\circ}C$. The results show that the increases in sweepback angle of the Flying-Wing configuration creates more efficient aerodynamic performance.

The leading edge of a low-drag super-cavitating foil has been made to be thick enough by using a point drag which is supposed to be a linear model of the Kirchhoff lamina. In the present paper, the relation between the point drag and the Kirchhoff lamina is made clear by analyzing the cavity drag of both models and the leading edge radius of the point drag model and the lamina thickness of Kirchhoff\`s profile K. The matched asymptotic expansion is effectively made use of in designing a practical super-cavitating fool which is not only of low drag but also structurally sound. Also it has a distinct leading edge cavity separation point. The cavity foil shapes of trans-cavitating propeller blade sections designed by present method are shown.

The vortical flows over sharp-edged delta wings with and without a leading edge extension have been investigated using a computational method. Three-dimensional compressible Reynolds-averaged Navier-Stokes equations are solved to provide an understanding of the effects of the angle of attack and the angle of yaw on the development and interaction of vortices and the aerodynamic characteristics of the delta wing at a freestream velocity of 20 m/s. The present computations provide qualitatively reasonable predictions of vortical flow characteristics, compared with past wind tunnel measurements. In the presence of a leading edge extension, a significant change in the suction pressure peak in the chordwise direction is much reduced at a given angle of attack. The leading edge extension can also stabilize the wing vortex on the windward side at angles of yaw, which dominates the vortical flows over yawed delta wings.

Steady state flow calculations are conducted for the newly-designed turbo-pump inducers to validate the performance of Tascflow code. Hydrodynamic performance is evaluated, and structures of the passage flow and leading edge recirculation are also investigated. The calculated results show good coincidence with the experimental data of the static pressure performance and velocity profiles near the leading edge. Upstream recirculation, tip leakage and vortex flow at the blade tip and near leading edge are main sources of pressure losses. Amount of pressure losses from the upstream to the leading edge corresponds to that of pressure losses through the whole blade. The total viscous losses are considerably large due to the strong secondary flow.

This study was to describe the process on experiences of self-leading leisure activities and develop a substantive theory that explains lifestyle in middle-aged office workers. The participants were 12 persons who had participated in self-leading leisure activities. Data were collected with in-depth interviews and analyzed by grounded theory in Strauss and Corbin. Through analyzing process, 28 concepts, 14 subcategories, and seven categories were deduced. The periods of process were divided four stages, plateau, the phage of recognition in social duties, the phage of strengthen in competency, and the phage of reconstruct in successful lifestyle. The core category, 'disclosing of self-esteem' incorporated the relationship between and among all categories and explained the process. The findings indicate that self-leading leisure activities helped to their own health and developed their social activities. Therefore, we would consider in developing health promotion program about favoring leisure activities factors for the middle age office worker.

The study aims at analysing the practical effects of "blended learning system" and participatory research methodology. The business programs are running by RDA. Even though many leading farms have been tried on binding technology and agribusiness, however business of farms in Korea are still in the beginning stage. The business program for leading farms of RDA is not only education program but also participatory research program. This program consist of on-line and off line, seminar and business homework etc. The main results of this paper are as follows: 1) to make organization of farms to accomplish business goals 2) to find out solution for urgent problems and subjects of farm management 3) to construct system for leading farms and on-line communities 4) to practice profitable business model for leading farms. Farms needs are not only technology transference, but business model for success of farm management.

The purpose of this study was to investigate the relationships between play behaviors and young children's playfulness in a variety of play space environments. The subjects were 150 4-year old children of 29 mixed-age classes in childcare centers of Seoul and Gyeonggi area. The results were as follows; (1) Their play behaviors differed according to their play environment in terms of classroom spaces. Solitary-active play behaviors were more frequently observed in large play spaces than small. (2) Leading participation, cognitive flexibility, voluntary full immersion, and total playfulness scores correlated negatively with reticent behavior. Leading participation, voluntary full immersion, and total playfulness scores, on the other hand, correlated positively with group play behavior. (3) In small play spaces, leading participation, voluntary full immersion correlated negatively with reticent behavior, but leading participation correlated positively with group play. In middle play spaces, cognitive flexibility correlated negatively with reticent behavior. In large play spaces, voluntary full immersion correlated negatively with parallel play, but leading participation, cognitive flexibility, expressions of joy, voluntary full immersion, and total playfulness score correlated positively with group play.

In this study, the effects leading and following tone with single frequency on sound lateralization were investigated. The tone with level difference and ISI(Inter Stimuli Interval) were used. The width of test tone was 2ms, leading tone and following tone were 10ms and 1kHz was used. The arrived time difference of subject's ears 0.5ms. We set four levels on each ISI and let them decide whether they hear the provided sound from left or right. As a result, it knew the fact that leading tone had more effect on sound lateralization than following tone.
