  • This paper proposes a qualitative reasoning approach for the spatial configuration of mechanisms that could be applied in the early phase of the conceptual design. The spatial configuration problem addressed in this paper involves the relative direction and position between the input and output motion, and the orientation of the constituent primitive mechanisms of a mechanism. The knowledge of spatial configuration of a primitive mechanism is represented in a matrix form called spatial configuration matrix. This matrix provides a compact and convenient representation scheme for the spatial knowledge, and facilitates the manipulation of the relevant spatial knowledge. Using this spatial knowledge of the constituent primitive mechanisms, the overall configuration of a mechanism is described and identified by a spatial configuration state matrix. This matrix is obtained by using a qualitative reasoning method based on sign algebra and is used to represent the qualitative behavior of the mechanism. The matrix-based representation scheme allows handling the involved spatial knowledge simultaneously and the proposed reasoning method enables the designer to predict the spatial behavior of a mechanism without knowing specific dimension of the components of the mechanism.

  • Comparative blood analysis was carried out to investigate the change of blood constituent in TAE-EUM-IN group and control group. RBC, WBC, hemoglobin, hematocrit, total protein, triglyceride, phospholipid, total cholesterol, LDL-cholesterol, HDL-cholesterol, BUN, creatinine, ACTH, cortisol and prostaglandin E and $F_2{\alpha}$ were measured. And the following results were obtained: 1. In the change of blood cell, the value of hematocrit showed significant difference, while that of RBC, WBC and himoglobin didn't. 2. In the change of protein, the value of total protein showed significant difference, but that of albumin didn't. 3. In the change of lipid and cholesterol in serum, the value of triglyceride, phospholipid, total cholesterol and LDL-cholesterol indicated significant difference, while that of HDL-cholesterol indicated significant difference, while that of HDL-cholesterol didn't. 4. The value of BUN in serum represented significant difference, but that of creatinine didn't. 5. The value of cortisol in plasma showed significant difference, but that of ACTH didn't. 6. The value of prostaglandin E and $F_2{\alpha}$ in plasma showed significant difference. These results suggest that investigation on hormones and blood constituents enables objectification in differentiation of four types of physical constitution.

  • The nucleate boiling heat transfer experiments are performed using a ternary refrigerant R407C which is a candidate of alternatives of HCFC 22. The boiling phenomena for R-32, R-125, and R-134a which are the constituent refrigerants of R407C are also investigated to give the foundation of theoretical research for the mixture component boiling. The nucleate boiling heat transfer coefficients of R407C is less than those of HCFC 22 which has the similar physical and transport properties. Since the experimental results show the deterioration of boiling heat transfer coefficients of ternary mixture refrigerants R407C, the boiling heat transfer coefficients of R407C cannot be obtained by the linear combination of boiling heat transfer coefficients from its constituent components R-32, R125, and R134a.

  • This study has been done to have a good grasp at the importance among the constituent elements of the rural healing tourism for working out the rural healing tourism planning. The above constituent elements were produced from the survey targeting the rural area-visiting visitors. For this study, 350 questionnaires were distributed to them and 306 out of them, valid, were collected. For the analysis of correlation among each item in the questionnaires, T-test, ANOVA were carried out. The results of the analysis of the questionnaires show that the consumers of the rural healing tourism have interest in the rural healing tourism regardless of their gender. The results also show that the consumers lay stress on the aspect of the infrastructure(H/W) more than contents-based aspect of the healing tourism(S/W). While especially, regarding healing tourism facilities or infrastructure, this study shows that there is significant difference in every item except gender item, regarding the contents and purpose of the rural healing tourism there is a significant difference among groups only in the item of age.

  • The object of my research is to inquiry into the immediate constituent and techniques of underwear after looking into basic theory of underwear, techniques by materials classified according to the matter of elasticity, and studying flat pattern and draping which are basis of corset and brassiere structure focusing on corsetry among underwears and production techniques. Various papers are referenced for theoretical study and the elements and techniques of underwear are analyzed based on photographical materials. This paper concludes as follows. To make the flat pattern of corset and brassiere fit to the body tightly, design dart two times without any space and draw smaller than the body. To support the breast sufficiently, move the side seam 1¼″ to the front panel and the seam should pass the apex in all occasions. For draping, dart should be added into short of elasticity materials in the past but dart is no use these days since the material today is extremely elastic. It is possible now to show the body line with only the seam or a pattern. In a case of elastic material, set the elastic direction to the grain line and have a draping as pulling from the center to the out side. As production technic, for an hem, put a zigzag stitch in elastic materials with a 10-20% short elastic band, pulling the band. Then make 3/16″-1/4″ short inseam.

  • The purpose of this research was to find out types of consumers for low price cosmetics in domestic market. And on the presumption that there would be differences on impact of brand image and brand loyalty depending on types of consumers, this study started from the possibility of establishing marketing strategy from the standpoint from such difference in types of consumers. Accordingly the classified types of consumers were presented on the basis of similar research data and data published in relevant professional literature. Analysis was undertook on kinds of impact of brand image, brand satisfaction, brand sense of identity and brand attitude which were constituent elements of brand assets on brand loyalty. Analysis showed that causative relationship between constituent elements of branch assets is different depending on types of consumers. Result of this study suggests that there is a certain need for reviewing types of consumers in order to heighten level of brand loyalty in connection with strategy for low price cosmetics brand marketing in domestic market.

  • To measure the moisture content, protein and viscosity of brown and milled rice with Near Infrared Reflectance(NIR) analyzer, the comparison and analysis of the data from the chemical analysis and NIR analyzer were conducted. The purpose of this study is to find out the fundamental data required for the prediction of rice qualify and taste rank, and to develop a measuring method of constituents and physical characteristics of domestic rice with NIR analyzer. The important results can be summarized as follows. 1. The $r^2$ and SEC of moisture calibration from brown rice powder were 0.87 and 0.09 respectively, those of milled rice powder were 0.95 and 0.08 respectively. 2. The $r^2$ and SEC of protein calibration from brown rice powder were 0.83 and 0.20 respectively, those of milled rice powder were 0.86 and 0.20 respectively. 3. The $r^2$ and SEC of viscosity calibration from brown rice powder were 0.36 and 15.50 respectively, those of milled rice powder were 0.55 and 12.98 respectively. Further study is required to develop better prediction model for viscosity. It is necessary the continuous study including wavelength selection, because $r^2$ is small for practical use. 4. The regression equation for one rice variety was nearly coincident with other. Therefore, it is required that the prediction model should be developed for the all rice samples.
