For improving high-safety, convenience, and ride comfort, the automotive design suffers from radical increase of the weight, the recycling-related rules, regulations on the waste gas, and environmental protection of the resources. Among them, it is well known that the weight increase is the most critical. Thus, in order to minimize the weight of the body-in-white that takes up 20-30% of the whole weight of the automobile, most automotive manufacturers have attempted to develop the aluminum intensive body-in-white using aluminum space frames. In this research, the crush test and simulation for aluminum extrusions are performed to evaluate the collapse characteristics of that light weighted material. Also. the same test and simulation was done for aluminum extrusions filled with structural foam. Then, these results are analyzed and compared. From these studies, the effectiveness of structural foam is evaluated in improving automotive crashworthiness. Finally, the design strategy and guideline of the structural form are suggested in order to improve the crashworthiness for aluminum space frame in the vehicle.

In this study, unsistered, pre-sintered and sintered low purity alumina ceramics were machined with various tools to clarify the machniability, the optimum tool materials and the optimum tool materials and the optimum cutting conditions. The maon conclusions obtained were as follows. (1) Machined withalloy steel tool, the machinabilty of te pre-sintered ceramics becomes better with the decrease of pre-sintering temperature, but that of unsintered ceramics(white body) was extremely poor. (2) In the case of carbide tool K01, the tool life in machining white body was the longest, and the machinabilty of pre-sintered ceramics becomes poorer with the increase of the pre-sintering temperature. (3) In the case of ceramic tool, the 10000-1100 .deg. C pre-sintered ceramics showed te best machinability within a certain cutting speed range. So far as dry machining, the above combination and conditions showed the highest productivity. (4) When the pre-sintered ceramics were wet machined withsintered diamond tool, the tool life becomes extremelylong, and higher cutting speed can be can be used than in the case offull-sintered ceramics. The productivity of wet cutting is much higher than that ofdry cutting.

Objective: Our study provides information on phenotypes of local chickens and guinea fowl and their body measures as well as on major genes in local chickens in northern Ghana. Methods: Qualitative and morphometric traits were recorded on 788 local chickens and 394 guinea fowl in urban households in Tamale, Ghana. Results: The results showed considerable variation of color traits and numerous major genes in local chickens, while color variations and related genotypes in guinea fowl were limited. In local chickens, white was preferred for plumage, whereas dark colors were preferred for beak and shanks. More than half of the chickens carried at least one major gene, but the contributions of single gene carriers were low. All calculated allele frequencies were significantly lower than their expected Mendelian allele frequencies. We observed higher mean body weight and larger linear body measures in male as compared to female chickens. In female chickens, we detected a small effect of major genes on body weight and chest circumference. In addition, we found some association between feather type and plumage color. In guinea fowl, seven distinct plumage colors were observed, of which pearl grey pied and pearl grey were the most prevalent. Male pearl grey pied guinea fowl were inferior to pearl grey and white guinea fowl in terms of body weight, body length and chest circumference; their shank length was lower than that of pearl grey fowl. Conclusion: Considerable variation in qualitative traits of local chickens may be indicative of genetic diversity within local chicken populations, but major genes were rare. In contrast, phenotypic and genetic diversity in local guinea fowl is limited. Broader genetic diversity studies and evaluation of trait preferences of local poultry producers are required for the design of appropriate breeding programs.

When expressing Jesus Christ visually in the medieval Christian paintings, the most important issue was portraying Christ's divinity and humanity in a balanced manner; showing both attributes as Son of God and a human being. The purpose of the study is to examine both the formative and the symbolic characteristics of divinity and humanity on Christ's clothes in the Medieval paintings, Baptism of Christ. In the paintings, there are iconographical devices to show His divinity including God, Holy Spirit, the Trinity and the Jordan River. But Christ's body is definite evidence to show his humanity. In connection with the body, the clothes reveal Christ's humanity and divinity as well. Through this research, the study found that the divinity and humanity on the Christ's clothes in the baptism of Christ were as follows: Blue, gole, purple, and white are the emblem of divinity, while the colors red and white stand for the humanity of Christ. In addition, the divinity of christ is expressed through the decoration on the clothes, while the humanity of Christ is shown through the structured drapery and transparent material.

Objective: The purpose of this study was to investigate whether goose growth and feather characteristics are influenced by their line and feeding surroundings, inclusive of floor materials and types, since there are no reports regarding these factors. Methods: The 240 White Roman geese which were hatched and sex identified came from 3 commercial goose farms. They were randomly distributed to 24 pens depending on a completely random design. The study continued for 13 weeks and included 3 lines of commercial geese and 2 floor types (cement strip floor [CSF] or cement floor [CF]). Results: The day one gosling weight from A farm was lower than other two farms (96 g vs 107 and 115 g; p<0.001). Afterwards, the body weight, back length, keel length, chest girth and main wing feather length among 3 farms showed no significance difference prior to 12 weeks. The CF group showed heavier body weight, shorter back length, longer keel length, shorter chest girth and shorter main wing feather length than the CSF group prior to 12 weeks. The down weight in the CF was heavier than the CSF group (57.1 g vs 41.8 g; p<0.01) prior to 13 weeks. Conclusion: The body weight showed the positive relations for dry feather weight (r = 0.59), down weight (r = 0.69), percent of the down weight of live body weight prior to 13 weeks (r = 0.61).

Objectives : The objective of this study was to access the effect of Artemisiae capillaris herba Extracts on the organogenetic reproductive toxicity of New Zealand White rabbits when administered by oral gavage. Methods : Gestational New Zealand White rabbits were dosed from 6 days of gestation to 18 days of gestation. It was conducted in accordance with the recommendations of the KFDA Guideline for Detection of Toxicity to Reproduction for Medicinal Products. In addition, serum AST, ALT, LDH and ALP levels were detected with their necropsy and histopathological observation Results: No significant changes of body weights, gains and food consumption were demonstrated in all dosed groups compared to those of vehicle control group except for 2,000mg/kg-dosing group, which showed significantly increase of body weight compared to that of vehicle control group. Normal gross findings were demonstrated in all tested groups. No significant changes of number of corpora lutea, implantation, implantation rate, number of fetal death, loss rate of post-implantation, number of live youngs at C-section, survival rate of post-implantation, number of male live youngs at C-section, number of female live youngs, sex ratio of live young, external anomalies of live youngs and body weight of live youngs were demonstrated in all dosed groups compared to those of vehicle control group. Although some visceral variations such as thymic reminant in the neck, dilation of renal pelvis, dilated ureter and malpositioned left common carotid artery, no significant changes were demonstrated in all dosed groups compared to that of vehicle control group. Some malformations and variation were demonstrated with retardations. However, no significant changes were demonstrated in all dosed groups compared to that of vehicle control group. In addition, similar ossification numbers were detected in sternebrae, metacarpals, metatarsals, phalanges, cervical vertebrae, and sacral and caudal vertebrae. No Artemisiae capillaris herba Extracts treatment-related changes of serum AST, ALT, LDH and ALP levels were demonstrated in all dosed levels in this study. Conclusions : We could conclude that oral administration of Artemisiae capillaris herba Extracts hasn't an influence on the organogenetic reproductive toxicity.
