This study investigated the microstructure and the room and high temperature mechanical properties of Fe–Cr–B alloy manufacturedby metal injection molding. In addition, hot isostatic pressing was performed to increase the density of the material,and a comparison of properties was made. Microstructural observation confirmed a bi-continuous structure composedof a three-dimensional network of α-Fe phase and (Cr,Fe)2B phase. The HIPed specimen featured a well-formed adhesionbetween the α-Fe phase and boride, and the number of fine pores was significantly reduced. The tensile results confirmed thatthe HIPed specimen (RT to 900 °C) had higher strengths compared to the as-sintered specimen, and the change of elongationstarting from 700 °C was significantly greater in the HIPed specimen. Fractography suggested that cracks propagatedmostly along the interface between the α-Fe matrix and boride in the as-sintered specimen, while direct fracture of boridewas observed in addition to interface separation in the HIPed specimen.

쌀, 조 수수, 및 콩의 식이가 흰쥐의 성장 및 혈액 성상에 미치는 영향을 조사하기 위하여, 평균체중 180g의 Sprague-Dawley계 rat(♂) 각 5마리씩을 대조군(T_(0)), 쌀(T_(1)), 조(T_(2)), 수수(T_(3)), 콩(T_(4))급이군등 5개군으로 나누어 실온에서 6주간 사육하면서 사료섭취량, 급수량, 증체량과 6주후의 혈액상의 변화틀 조사하였다. 사료 섭취량은 대조군이 각 처리 실험군보다 높았으며 물의 급수량도 동일한 결과이었으며 그 순위는 쌀, 조, 콩, 수수 순으로 감소하였으며, 각 처리군의 증체량은 대조군 보다 낮았으며, 특히 수수는 초기보다 감소하였고, 각 처리군의 사료효율은 대조군보다 낮았으며 특히 수수처리군이 타 처리군보다 낮았다. 연액성상의 변희는 대조군에서는 큰 변화가 없으나 수수군에서 BUN, HOT지 다른군보다 높았으며 쌀의 처리군은 creatinine치가 높았고 조에서는 혈당치가 낮았으며, 콩에서는 LDH는 높았고, HGB, HCT, PI.T, RBC가 낮았고, 특히 콩 수수에서는 혈액상의 변화가 가장 컸으며 다른 실험군과 비교하였을 때 통계적인 유의성이 인정되었다. This study was conducted to investigate the effects of rice, millet, sorghum and soybean diet on the growth rate, daily intake feed ratio and change in hematology of male rats. The experimental male rats of 180g average weight were fed on control (T_(0)), rice (T_(1)), millet (T_(2)), sorghum (T_(3)) and soybean diet (T_(4)) for 6 weeks. The amount of daily feed and water intake supply in each diet group is higher than that of control group to as shown in the following order: rice, millet, soybean, sorghum. The growth ratio of each diet group is lower than that of control group. Especially, sorghum made each diet group reduce the weight even more than the initial weight. Control group is lower than each diet group in regard to the effective ratio of feed. Especially, the sorghum group is lower than other groups. Control group remained same in the change of hematology, however, sorghum group is higher than other groups for BUN, HCT. Rice group is higher in creatinine and millet group is lower in glucose content of serum than any other groups. Soybean group is higher in LDH but lower in HGB, HCT, PLT, RBC than control group. Especially, the soybean and sorghum groups showed a big change in hematology and had the statistic significance in comparison to other groups.

J.Vogt glaubte, daβ die antike Sklaverei in den demokratischen Landern Europas und Amerikas immer noch nicht die gebuhrende Aufmerksamkeit gefunden hade, wahrend sie in der kommunistischen Welt einer feststehenden Thorie eingfugt worden sei. Mein Aufsatz ist Einfuhrung in Europas Forschungsgeschichtlicher Uberblick von antike Sklaverei. Die Meinungen von Marx und Engels duften demnach nicht als absolut gultig empfunden werden, sondern nuBten Ansatzpunkte fur weituhrende Fragestellungen und neue Forschungen sein.

Teaching business ethics in undergraduate course is expanding gradully. How about MBA course ? This paper investigate teaching business ethics in MBA course. This paper uses telephone survey method and sample sizes are 30 graduate school of business administration. This paper finds following results. (1) Deans of graduate school of business administration recognize the strong needs of teaching business ethics in MBA course. (2) There are only two schools that open the business ethics related course. (3) The top reason why they do not open the business ethics course is low priority compared with other functional courses. This paper suggest integrating ethics into all the business curriculum and operating the re-education program of business ethics for improving the present situation.

1848년 이전 독일의 가장 뚜렷한 사회주의자로 여겨지는 Whilhelm Weitling도 초기에는 Lamennais처럼,종교적인 믿음으로 충만되어 있었음이 분명하다. Weitling 의 저술에는 또한 Saint Simon,Fourier,Cabet. Owen의 영향도 엿볼 수 있다. 방랑하는 재단사였던 Weitling 은 Marx,Engels 이전에 Paris에 <의인동맹>(후에는 공산주의자 동맹)을 조직하여 정치적인 성격을 나타냈다.
