The purpose of this study was to classify consumer groups according to the life style dimensions and to analyze conspicuous consumption, clothing shopping motives among consumer groups, and also to clarify relationships between demographic variables and the life style, conspicuous consumption, clothing shopping motives. The subjects were 329 women in their twenties living in Seoul. For data analysis, mean, factor analysis, cluster analysis, t-test, ANOVA, Duncan test were conducted. The results were as follows ; First, consumer groups were classified into the following five subdivisions : passive group, appearance consideration/self-realization group, appearance indifference group, family oriented/economic group, achievement oriented/active group. Second, the significant differences among the classified life style groups were found in conspicuous consumption and clothing shopping motives. Third, there were significant differences in life style, conspicuous consumption, clothing shopping motives according to demographic variables like age, occupation.

The repeatability error creeps in every corner of mechanical design as mechanical design becomes diverse and complicated. Inkjet printing has inherent repeatability error problem due to its nature of seamless incremental image synthesis of partial images. Without the calibration for the repeatability error realization of high print quality or enhancement of other printing performance could be impaired. Printer designers have met this recurrent problem even before the inception of inkjet print device and contrived various solutions as their own intelectual proprietary. Also, it is a trend to perform necessary calibration without painstaking human intervention. To come up with another useful and proprietary solution has become an important ingredient in inkjet printer design. This paper presents such a solution developed at Digital Printing Division of Samsung Electronics Company.

The use of Complementary and Alternative Medicine (CAM) is increasing in Norway. A growing number of nurses choose to offer CAM, and the purpose of the study presented in this article was to examine the reasons for their choices. Fieldwork including interviews with 20 nurses offering CAM was conducted. The results showed that the nurses in general are not satisfied with the public health service. They had four main reasons for their choice to offer CAM: 1. A desire to perform holistic nursing. 2. A tendency to value self-realization. 3. A wish to experience meaning in their work and develop a stronger professional identity. 4. A freedom to mix care and cure. The results of this study are also discussed in view of medicalization.

Hydrophobic and Superhydrophobic surfaces are promising technology for the surface finishing of metallic materials due to its water-repellency. Realization of highly water-repellent surface on aluminum and its alloys provides various functionalities for real application fields. In order to realize the hydrophobic/superhydrophobic surfaces on aluminum and its alloys, various technologies have been demonstrated. Especially, traditional anodic oxidation for aluminum has been widely employed for the morphological texturing of surfaces, which is essential to enhance the hydrophobic efficiency. De-wetting superhydrophobic surface on aluminum provides various exceptional properties, such as anti-corrosion, anti-/de-icing, anti-biofouling, drag reduction, self-cleaning and liquid separation. Nevertheless, the durability and stability of superhydrophobic surfaces still remain challenges for their actual applications in engineering systems and industry. In this review, the theoretical/experimental studies and current technical limitations on the hydrophobic and superhydrophobic surface using anodic oxidation of aluminum have been summarized.

The purpose of the study is to search for on teaching and learning to improve creativity in home economics education. It has been important for students to formulate and solve problems about home and family through creative thinking, home economics educators have to provide these teaching and learning methods. This research's methods were to search the importance of creativity in home economics education and the relevance between home economics and creativity, then to find the problems of some recent creativity education and formulate the assumption for creativity education in home economics education. Finally, it was presented the examples of teaching and learning to improve creativity. In above the process, we have to recognize as belows; 1. The teaching and learning methods in home economics education need the creativity for formulating problems and finding the elements which effect on practical problems. 2. It is properly selected to some teaching and learning methods in home economics education, and many methods to improve creativity may be included the assumptions for self-realization and moral responsibility.

This paper is to show design of robot manipulator which has 3-link using DC Motor and realization of control algorithm with IBM - XT Micro-computer connected. Gentral algorithm is applicated by position and pass control using point-to-point method. At first, this paper computes required angles on each joint in order to search desired position or path, and uses a voltage control with feedback from output of encoder and tachometer in real time. The application of control algorithm on position, velocity and force for each joint of manipulator by using self-tuning control is left for next study.

On this study, initial crack index was evaluated by performing FEM analysis to crack propagation from hydration heat for development of precast concrete. On the result, as increased the usage of hardening accelerator, initial compressive strength were improved and setting time also was shortened. Additionally, central temperature of concrete was increased, the reaching time for the highest temperature could be shortened. By the result to assess crack index, there was no problem about crack despite of growth of initial high hydration heating. This result guessed because of small size element when analyzed trough FEM, realization for mass concrete's crack index should be performed.

This paper presents Spectral-Domain optical measurement system using self-fabricated CCD sensor driver. The light source is a high brightness white LED and the detector is a 2048 array typed CCD image sensor. I have fabricated the CCD sensor driver to generate four pulse signals, which are the CCD-driving pulses. Using this Spectral Domain optical measurement system, the distance value between the reference mirror and the sample mirror can be obtained successfully.

Metalorganic chemical vapor deposition (MOCYD) techniques have been applied to fabricate semiconducting ZnO thin films and nanostructures, which are promising for novel optoelectronic device applications using their unique multifunctional properties. The growth and characterization of ZnO thin films on Si and $SiO_2$ substrates by MOCYD as fundamental study to realize ZnO nanostructures was carried out. The precise control of initial nucleation processes was found to be a key issue for realizing high quality epitaxial layers on the substrates. In addition, fabrication and characterization of ZnO nanodots with low-dimensional characteristics have been investigated to establish nanostructure blocks for ZnO-based nanoscale device application. Systematic realization of self- and artificially-controlled ZnO nanodots on $SiO_2/Si$ substrates was proposed and successfully demonstrated utilizing MOCYD in addition with a focused ion beam technique.

This study attempted to find out how much stress Dental Technicians of working in Dental Laboratory have built up in the midst of their daily lives are according to their sex, age, duration of work and their kinds of positions. After self-administered questionnaire were distributed by direct to 230 technicians samplely selected from dental laboratories in Seoul and Pusan of whom 163 technicians responded from october 1 through october 13, 1994. Analysis of the data was processed by t-test, $X^2$-test, ANOVA. This results are as follows. 1. Levels of Stress of the total 163 respondents by sex is not higher among male than female(p>.05). 2. Levels of stress - 36.2%(74 Dental technicians) of all Dental technicians were in stress on the whole and 9.2%(15 Dental technicians) of them were in a serious situation by accumulated stress. 3. Realization of stress - 10.1%(16 Dental technicians) of the dental technicians and 89.9%(143 Dental technicians) were found out to be in a dangerous sign or in a situation by accumulated stress. Further studies which a big size and a delicate method of measuring their general characteristics are needed.
