  • In recent years, the concern of designing multi-stage gear drives ha increased with more application of them in high-speed and high-load. Until now, however, the researches on the design of gear drives have been focused on single gear pairs. Thus the design practice for multi-stage gear drives has been depended on experiences and expertise of designers and carried out commonly by trial and error. We propose an automation algorithm for the design of two-and three-strage cylindrical gear drives. The two types of dimensional design processes have been proposed to determine gear dimensions in a formal way. The first design process(Process I) uses to total volume of gears to determine gear ration , and uses K factor , unit load and aspect ration to determine gear dimensions, The second one(Process II) makes use of Niemann's formula and center distance to calculate gear ratio and gear dimensions. Process I and Process II employ material date from AGMA and ISO standards, respectively. The configuration design determines the positions of gears with minimizing the volume of gearbox by using a simulated annealing algorithm. The availability of the design algorithm is validated by the design examples to two-and three=stage gear drives.

  • The purpose of this study was to analyze the effectiveness of negative appeal ads taking social problems as their themes. Two social problem ad themes concerning abortion and drug addiction were selected as stimulus. Questionnaires consisted of questions about affective response cognitive evaluation consumer's characteristics(sex, clothing involvement social problem involvement) and the ad and brand attitudes They were distributed to 200 high school students in Seoul. Results were : 1 The affective response consisted of 4 dimensions(negative inactivating activating positive) and the cognitive evaluation had 3 dimensions(utility·persuasive power creativity awareness) 2. Creativity and awareness dimensions and the ad attitude had positive influence on the brand attitude for the abortion theme ad,. Creativity dimension and consumer's clothing involvement had positive influence on the brand attitude for the drug addiction theme ad . Especially the affective response had no significant influence on the brand attitude. This result suggests that in case of negative appeal ads the affective response does not necessarily degrade the brand attitude while positive cognitive evaluation on creativity and awareness of the could influence the brand attitude favorably through raising attention to the brand resulting in high effectiveness of the ad.

  • The purpose of this study was to find out differences of visual evaluation according to perceiver's gender, clothing silhouette, and body exposure of the lingerie look. Subjects were 246 college males and females in Seoul. The visual evaluation of the lingerie look was divided into four image dimensions: elegance, individuality, fascination, and activity. Silhouette had significant influences on the perception of elegance and activity. The hourglass silhouettes were evaluated more elegant and active than the tubular silhouettes. The body exposure had significant influences on the evaluation of elegance, individuality, fascination, and activity. The shoulder and the back exposure were estimated high in fascination, the breast exposure low in elegance, and the waist exposure high in individuality and activity. Individuality, fascination, and activity had interaction effects by perceiver's gender and body exposure. Males estimated the waist exposure to be more fascinating than females, and females estimated the breast exposure to be less active than males. There were significant interaction effects in evaluating the 4 image dimensions according to the silhouette and body exposure. The shoulder and the leg exposure of the hourglass silhouettes were estimated more elegant than those of the tubular silhouettes. Dimensions of clothing image which influenced on preference of lingerie look were different between males and females.

  • As finger joint method has a high rate of yield and high strength and ease in working, it has been widely used as an end joint method for solid wood and wood based-material. Therefore, we end-joined the material of Pinus densiflora, Quercus variabilis and populus euramericana with polyvinyl acetate adhesive and resorcinol phenol resin adhesive. The effect of difference (0, 0.15, 0.3, 0.45mm) between the dimensions of tip width and root width of the finger (DTRW) on bending strength properties was as follows: 1. In the case of polyvinyl acetate adhesive, DTRW had no effect on bending modulus of elasticity(MOE) and modulus of rupture(MOR) of the three kinds of species, because their bonding layers were destroyed by slippage, not their woody parts. 2. In the case of resorcinol phenol resin adhesive, the material of Quercus variabilis showed an optimal result at 0.15 or 0.3 of DTRW, while the poplar did at 0 of DTRW 3. The differences in efficiency ratio of bending MOR of populus euramericana, Pinus densiflora and Quercus variabilis species according to the kind of adhesive were 13-29%, 23-30% and 45-53%, respectively.

  • This study aims to test whether and to what extend national culture affects the readiness of business-to-consumer (B2C) e-commerce across the world. We regress two sets of data at national level: (1) the ratings of two main dimensions of Hofstede's national culture framework, uncertainty avoidance and individualism, and (2) UTCTAD B2C e-commerce index value. A sample of 83 countries was tested in this study. Several control variables at national level are included in our regression model. We find that these two cultural dimensions have an effect on the readiness of B2C e-commerce in various ways. We find that countries with high individualism score have high index value of B2C e-commerce development. We discuss the implications of these findings for B2C e-commerce developing strategies. We then call for designing relative policies with full consideration on national culture to promote the development of B2C e-commerce. In addition, we identify the limitations of the study and propose recommendations for future research. This study is the first one to use UNCTAD data on B2C e-commerce to explore the relationships between two dimensions of Hofstede's national culture and the readiness of B2C e-commerce and adds to the knowledge of literature in this research field.
