    A large volume of lubrication oil is used in factories performing metal cutting work. However, water-soluble oil decays due to bacterial breeding, and the resulting smell is problematic in the working environment. Drugs using microorganisms are available to prevent this bacteria-induced decay, but the effects and mechanisms have yet to be examined. So, in this study, the sterilization and growth-inhibiting effect of Biological-material-solution (BMS) on putrefactive bacteria were investigated. The characteristics of BMS, especially its antioxidant activity, were confirmed. In addition, the relationships were considered.
    Antioxidant activity was shown by BMS. The activity weakened when BMS was filtrated. A weak sterilizing effect was also shown by BMS. However, it was insufficient to control putrefaction and the putrid odor. Further, there was no association between the antioxidant activity and sterilization effects. The antioxidant actions are therefore not the main factors which control putrefaction of a water-soluble oil. The dose needed to inhibit a certain number of putrefactive bacteria was associated with the quantity of BMS added.
    In conclusion, BMS suppressed the activity of putrefactive bacteria, and did not exhibit bactericidal activity. This suppressant activity was dependent on the substrate metabolized from BMS. In this study, it was necessary to remove live microorganisms from BMS in the examination method. So, when live microorganisms exist, the suppressant effect will strengthen, or the effective time will become longer. Actual on-site examination is necessary for verification, and a future study is anticipated.

    Background : More than 2 million Japanese children currently attend day care centers. However, when ill, children cannot generally participate in group activities, often requiring their working parents to take time off to care for them. Additionally, many parents cannot take leave to attend to their sick children, meaning that they are likely to still send them to the day care center, thereby leading to the possible spread of infectious diseases to the other children. In this study, we investigated working mothers' knowledge of the leave available to them when their day-care-attending children are sick.
    Methods : In November 2012, we conducted a cross-sectional study using a self-administered questionnaire among primary caregivers (n=560) of children in day care centers in Kokubunji, Kunitachi and Kodaira cities in Tokyo. Among the respondents, 318 working mothers of children were considered eligible for the analysis.
    Results : The questionnaire responses revealed that 205 subjects (64.5%) desired to take leave to look after their sick children themselves. However, most working mothers were not given adequate nursing leave. Moreover, approximately half (151, 47.8%) of the subjects did not even realize that they could take nursing leave. Part-time employees seemed to have less knowledge than full-time ones regarding leave, as 73 (83.9%) part-time employees did not recognize that they had leave allotted as nursing leave.
    Discussion : In this study, approximately half of the subjects did not realize that nursing leave was available to them. Furthermore, it is especially difficult for part-time employees and recently hired workers to access the leave system. It is crucial to maintain a leave system and to improve workers' recognition of their legal right to nursing leave, as it is important for nursery-school-age children to obtain as much rest as possible when they are in poor physical conditions.

    Objectives : The experience and perception to support the intention of the female family caregivers living in the secluded heavy snowfall area who take care of their family at home and their characteristics seen in the community through analysis of the kinship type.
    Methods : The samples are from 7 caregivers living in A area. The research was analyzed quantity and inductively after picking up care perception.
    Result : From their experience, the caregivers have got perception of nursing care as follows.
    1, They came to the reality and love the caretakers more.
    2, They strengthened the family bond, hoping to spend time together and protect their family.
    3, They are helped by their neighbors and supporters and maintain balance between nursing care and their own life.
    4, Regardless of the kinship type differences, all caregivers deepened their family bond, love the caretakers and are supported by the community.
    Discussion : A area has established medical care service. Helped by their neighbors and supporters, the caretakers deepened the family bond and love the caretakers more.
    The analysis of the kinship of the caregivers shows that they have their concern as wife, daughter, or daughter-in-law, based on their family problems. The caretakers took a cognitive approach to take on nursing care.
    As a result, they deepened the family bond and their affection toward the caretakers through nursing care. Getting support from the professionals, they've developed their intention to continue nursing care.
