New System for Environmental Management Evaluation
Kametani, Tsuyoshi The Korean Society for Quality Management 2004 The Asian Journal on Quality Vol.5 No.1
In Japan, where ISO14001 certifications have passed the 10,000 mark, the need for environmental management has taken firm root among companies. However, in the small-and medium-enterprise sector, and among tiny businesses, there are firms not obtaining ISO certification due to their concern about human resources and increased work load. On the other hand, among businesses that have already succeeded in gaining ISO certification. one does not sense any growth with regard to the continual improvement. Voices from certain quarters indicate there is a lack of incentive to keep on improving. With this background, we herewith present a new system to evaluate the level of environmental management in a company by means of a 5-step system.

<P>Achieving high critical current density (<I>J</I> <SUB>c</SUB>) under a high magnetic field in Fe based superconductors is indispensable for practical applications. Here we report that high critical current density over 1 MA cm<SUP>−2</SUP> in high field (13 T) can be achieved in BaZrO<SUB>3</SUB> (BZO) incorporated Ba(Fe,Co)<SUB>2</SUB>As<SUB>2</SUB> (Co-Ba122) thin film grown on CaF<SUB>2</SUB> substrate using pulsed laser deposition. The magnetization <I>J</I> <SUB>c</SUB> of Co-Ba122 thin film incorporated with 2 mol.% BZO reaches 1.3 MA cm<SUP>−2</SUP> (<I>H</I>ǁ<I>c</I>, 13 T and 4.2 K), 14 times higher than that of pure Co-Ba122 thin film. Transmission electron microscopy observation revealed that BZO forms nanorods of ∼4 nm in average diameter with mean separation of 10–11 nm which corresponds to a matching field of about 17–20 T. Incorporating BZO in Co-Ba122 thin films led to a strong vortex pinning effect and a significant enhancement of <I>J</I> <SUB>c</SUB> because a high density of BZO nanorods could form in the superconducting matrix without significant degradation of <I>T</I> <SUB>c</SUB>, and the diameter of BZO nanorods is approximately twice the coherence length of Co-Ba122 (<I>ξ</I> <SUB>ab</SUB>(0) ∼ 2.5 nm) which is the optimal size as pinning centers.</P>

Objective: Microminipig (MMP) is a miniature pig with an extra small body size for experimental use. In the present study, the occurrence of stillbirths and their genetic association with swine leukocyte antigen (SLA) class II haplotypes were evaluated in a population of MMPs. Methods: The occurrences of stillbirth and genetic association with SLA class II haplotypes using 483 stillborn and 2,246 live piglets, and their parents were compared among the three groups of newborn piglet litters; an all stillborn (AS) group consisting of only stillborn piglet litters, a partial stillborn (PS) group consisting of stillborn and live piglet litters, and an all alive (AA) group consisting of only live piglet litters. Results: The incidence of stillborn piglets was 483/2,729 (17.7%). Distributions of litter sizes, numbers of stillborn piglets in a litter, parities, and gestation periods were distinct among the three groups. The frequencies of low resolution haplotype (Lr)-0.7 or Lr-0.23 were higher in the AS group than in the PS or AA groups. In sires, the frequency of Lr-0.7 associated with the AS group was significantly higher in the AS group than with the AA group. In dams, the frequency of Lr-0.23 was significantly higher in the AS group than in the PS or AA groups, whereas the frequency of Lr-0.7 was not significantly different. Conclusion: The incidence of stillborn piglets in MMPs appears to be higher than those in other pig breeds. Several traits related with stillbirths such as the number of stillborn piglets and parities of the AS group were different from those of the PS and AA groups. Specific SLA class II haplotypes were associated significantly with a high incidence of stillbirths and could be used as genetic markers to adopt breeding strategies to lower the rate of stillbirth in MMPs.
