This study describes aerodynamic noise of high speed wind turbine system, which is invented as a new concept in order to reduce the torque of main shaft, for design parameters of the rotor blade. For parametric study of high speed rotor aerodynamic noise, Unsteady Vortex Lattice Method with Nonlinear Vortex Correction Method is used for analysis of wind turbine blade aerodynamic and Farassat1A and Semi-Empirical are used for low frequency noise and airfoil self noise. Parameters are chord length, twist and rotational speed for this parametric research. In the low frequency range, the change of noise is predicted the same level as each parameters varies. However, in case of broadband noise of blade, the change of rotational speed makes more variation of noise than other parameters. When the geometric angles of attack are fixed, as the rotational speed is increased by 5RPM, the noise level is increased by 4dB.

This paper identifies the current practice and problems of the performance appraisal system at a typical Korean company. We developed a general framework of performance appraisal system consisted of five subsystems. Along the components of this framework, we reviewed the internal documents and recent appraisal data in the firm, and analyzed the interview and questionnaire survey outcomes collected companywise. Main findings are as follows. The appraisal results are used solely for promotion decisions, and almost never for career development, rewarding, relocation and so on. The appraisal items are not clear in meaning, not comprehensive in scope, and do not adequately reflect characteristics of different jobs. The appraisal is made by superiors only, and needs to be complemented by peer and/or self reviews. The employees are appraised on the basis of subjective judgments of the superiors. The appraisal data are being accumulated, but due to inadequate formation and insufficient programs the database is not being used for the detection and correction of appraisal tendencies and errors. Appraisal results are not fedback to the employees for the constructive information exchange. Accordingly they perceive the effectiveness of the appraisal system as very poor. Finally, the implication of our finding for other companies is briefly discussed.

Double-blade vertical axis wind turbines (DB-VAWTs) can improve the self-starting performance of lift-driven VAWTs. We here propose the quadruple-multiple streamtube model (QMS), based on the blade element momentum (BEM) theory, for simulating DB-VAWT performance. Model validity is investigated by comparison to computational fluid dynamics (CFD) prediction for two kinds of two-dimensional DB-VAWT rotors for two rotor scales with three inner-outer radius ratios: 0.25, 0.5, and 0.75. The BEM-QMS model does not consider the effects of an inner rotor on the flow speed in the upwind half of the rotor, so we introduce a correction factor for this flow speed. The maximum power coefficient predicted by the modified BEM-QMS model for a DB-VAWT is thus closer to the CFD prediction.

In order to understand Changeologically on the meaning of FCST's TMJ (temporo-mandibular joint) treatment procedure, Yi, Shike, Bi, Gen trigrams concerning the jaw and change by treatment were analyzed from the viewpoint of semiotic context of hexagon and holistic interpretation on disease. Yi is meant by jaw but actually indicates mouth made by maxilla and mandible, and it's characters are related with nourishing by aliment and words. But when we eat and speak in the daily life, jaw does not nourish properly it's own body by bad habit or postures. For the treatment of this ill state, there needs punishment and correction symbolized with Shike. Shike has fourth nine meaning obstacles between the two strong lines in the upper and lower end, and so it has the function of mastication and get rid of the fourth nine metaphorically indicating subluxation of axis using CBA and auxiliary measures of four movement or laughing methods. Bi expresses the achievement and effects of consecutive mastication process implicating normalized manifestation of jaw and its linked spinal function. Gen symbolizes removing selfish motive or partiality in advance and reaches the best state of the saint righteously self-nourishable human being.

We tried to find out parents' satisfaction and needs for foodservice quality of the childcare centers with an intention of improving it. Self-completed questionnaires were randomly collected from the parents of children in 174 childcare centers around Asan and were analyzed. Most of respondents were mothers who were housewives with college degrees (69%) in their 30's (80%). They thought nutrition (50%) and food hygiene (43%) were the most important factors for decision. Eighty percent of parents recognized the strong relationship between foodservice quality and childrens' mental and physical development. Most centers (94%) were delivering menu notices home, so parents well recognized the center's foodservice situation and problems of their kids' eating habits. The parents' satisfaction scores were 3.26 out of 5-point scale. The biggest dissatisfaction was from no variation in menu, but remarkable appreciation was from the effect of foodservice on the correction for kids' unbalanced diet habit. They had demands for improvement of nutritious menu and professional nutrition teacher in charge of foodservice and nutrition education for children and also for parents.
