Im 18. Jahrhundert stritt man urn allgemeing$\"{u}$ltige Kriterien f$\"{u}$r die Kunstkritik, welche ebenda aufzubl$\"{u}$hen begann. Im Zentrum dieser Auseinandersetzung, die uns als "Laokoon-streit" bekannt ist, befanden sich Johann Joachim Winckelmann einerseits und ein franz$\"{o}$sischer Bildhauer Etienne-Maurice Falconet(1716-1791) andererseits. Die beiden waren von ganz unterschiedlichen Kunstideen $\"{u}$berzeugt. Obwohl sie niemals zusammentraf, fielen sie in eine heftige schriftliche Diskussion. Wie bekannt, vertrat Winckelmann den aufkommenden Klassizismus. Er setzte die griechische Kunst auf die h$\"{o}$chste Rangstufe auf und bezeichnet sie als Tr$\"{a}$ger der sogenannten "edlen Einfalt und stillen Gr$\"{o}{\beta}$e, die sonst in der Natur verborgen bleibe. Nach Winckelmann sollte der K$\"{u}$nstler die griechischen Vorbilder wie Apollo von Belvedere und Laokoon nachahmen, um das wesentlich Sch$\"{o}$ne zu erlernen. Falconet $\"{u}$bte eine scharfe Kritik gegen die Meinung Winckelmanns und die Diletantismus in der Kunstkritik aus. Selbst als Theoretiker warf er vor, dass die Klassizisten um ihr dogmatisch struktuiertes Lehrgeb$\"{a}$ude willen alle andere Eigenschaften der Kunst sowie Kunstwerke $\"{u}$bersahen und ihre Apotheose der klassischen Kunst auf die Entwicklung der Kunst eher als Hindernis wirkte. Im besonderen Hinblick auf den Ausdruck der menschlichen Leidenschaft distanzierte Falconet sich von der Lehrmeinung des Klassizismus, n$\"{a}$mlich Zur$\"{u}$ckhaltung derselben Leidenschaft wegen der idealen Sch$\"{o}$nheit. Vor dem Laokoon teilten Falconet und die Klassizisten ihre Meinung un$\"{u}$berbr$\"{u}$ckbar voneinander. F$\"{u}$r diese war der Laokoon die Repr$\"{a}$sentation des erhabenen Menschen, der leidet, ohne seinen Affekt zu enth$\"{u}$llen. Im Gegensatz sah Falconet in demselben Werk einen erlungenen Ausdruck des menschlichen Gef$\"{u}$hls. Sein Deb$\"{u}$twerk ist also die Visualisierung seiner Kunstauffassung. Unter Einfluss Pierre Pugets sowie seines Lehrers Jean-Baptiste Lemoyne bem$\"{u}$ht er sich darum, den Ausdruck der menschlichen Leidenschaft durch kunsttechnische Leistung und wissenschaftliche Forschung zu erstarken. Daraus ergab sich die expressive Ausdrucksform des Affekts. In diesem Fall verband sich Falconet mit der Tradition des barocken Kunstwollens, aber er ging einen Schritt weiter, indem er die Ausdrucksweise noch realistischer und lebendiger zu machen vermag. Faconet war vielleicht der einzige K$\"{u}$nstler, der Vorteile det barocken Kunst ausnut zen konnte, ohne dabei die klassische und realistische Formensprache zu verlieren. Dutch sein Werk und seine theoretischen Schriften er$\"{o}$ffnete er neue Prinzipien sowohl f$\"{u}$r die Kunstpraxis als auch f$\"{u}$r die Kunstkritik, deren wesentliche Sinn jedoch erst in der Romantik anerkannt wurde.

Recently renewable energy such as offshore wind energy takes a higher interest due to the depletion of fossil fuel and the environmental pollution. This paper deals with multi-body dynamics (MBD) analysis technique for offshore wind turbine system considering aerodynamic loads and Thevenin equation used for determination of electric generator torque. Dynamic responses of 5MW offshore wind turbine system are evaluated via the MBD analysis, and the system is the horizontal axis wind turbine (HAWT) which generates electricity from the three blades horizontally installed at upwind direction. The aerodynamic loads acting on the blades are computed by AeroDyn code, which is capable of accommodating a generalized dynamic wake using blade element momentum (BEM) theory. In order that the characteristics of dynamic loads and torques on the main joint parts of offshore wind turbine system are simulated similarly such an actual system, flexible body modeling including the actual structural properties are applied for both blade and tower in the multi-body dynamics model.

As the economic matters are involved, applying the WEC, which is used for controlling waves as well as utilizing the wave energy on existing breakwater, is preferred rather than installing exclusive WEC. This study examines the OWC mounted on a pressurized air chamber floating breakwater regarding the functionality of both breakwater and wave-power generation. In order to verify the performance as a WEC, the velocity of air flow from pressurized air chamber to WEC has to be evaluated properly. Therefore, numerical simulation was implemented based on BEM from linear velocity potential theory as well as Boyle's law with the state equation to analyze pressurized air flow. The validity of the obtained values can be determined by comparing the previous results from numerical analysis and empirically obtained values of different shapes. In the actual numerical analysis, properties of wave deformation around OWC system mounted on fixed type and floating type breakwaters, motions of the structure with air flow velocities are investigated. Since, the wind power generating system can be hybridized on the structure, it is expected to be applied on complex power generation system which generates both wind and wave power energy.

In the present study, aerodynamic load analysis for a floating off-shore wind turbine was conducted to examine the effect of periodic platform motion in the direction of 6-DOF on rotor aerodynamic performance. Blade-element momentum method(BEM) was used for a numerical simulation, the unsteady airload effects due to the flow separation and the shed wake were considered by adopting a dynamic stall model based on the indicial response method. Rotor induced downwash was estimated using the momentum theory, coupled with empirical corrections for the turbulent wake states. The periodic platform motions including the translational motion in the heave, sway and surge directions and the rotational motion in the roll, pitch and yaw directions were considered, and each platform motion was applied as a sinusoidal function. For the numerical simulation, NREL 5MW reference wind turbine was used as the target wind turbine. The results showed that among the translation modes, the surge motion has the largest influence on changing the rotor airloads, while the effect of pitch motion is predominant for the rotations.

The purpose of this study was to investigate(Ⅰ) the effect of a masculine-feminine image in women's suit on the perception of the wearer's occupational characteristics and suitability of the clothing for certain occupations, and (2) the effect of perceiver's sex, sex-role attitudes, and occupation on the perception formed by the function of clothing cues. The research design of the study consisted of 2(pink and navy blue colors) × 4(masculine and feminine forms) factorial design of a suit. The experimental materials developed for this study were a set of stiuli and 2 response scales. The stimuli consisted of 8 drawings of woman's clothing made by systematic manipulations of 2 independent variables(color and form) in drawings of suit. The dependent variables were the perceptions of the wearer's occupational characteristics and suitability of the masculine or feminine clothing for certain occupations. Occupational characteristics were measured with a 7-point semantic differential scale composed of 21 bipolar adjectives. Perception of ccupational suitability was assessed with 12 items of 5-point Likert type questions. In addition, the Bem Sex-role Inventory was used to assess perceiver's sex-role attitudes. The subjects consisted of 393 men and 389 women, whose occupations were classified as professionals, secondary school teachers, and white-collar workers. They were randomly assigned to one of 8 suit. The data were analyzed by factor analysis, MANOVA, ANOVA, Mean and S.D. Three factors emerged to account for the perception of occupational characteristics. These factors were given the titles of (1) activity, (2) potency, and (3) evaluation factors. The activity factor was the largest, including 9 adjectives. Differences in the form of the suit had effects on potency and evaluation for both sexes, while it also had some effect on activity for women. The color of the suit had some effect on evaluation for both sexes. Strong effects of color and form on the suit were seen in perception of occupational suitability for the occupations of attorney(masculine) and secretary(feminine). On suitability for secondary school teaching occupation, the effects of color and form of suit differed by sex of the subjects. Perceiver's sex-role attitudes and occupation paritally influenced the perception of the wearer's occupational characteristics and suitability of the clothing for certain occupations. In summary, a masculine-feminine image of clothing had a significant effect on the perception of occupational characteristics as well as on suitability of the clothing for certain occupations. Thus, the results of the study support the implicit personality theory on person perception and also the stereotypes of sex-roles on the perception of occupational suitability.
