      The microbial degradation of bisphenol A (BPA), 4-n-octylphenol (OP) and 4-n-nonylphenol (NP), endocrine-disrupting chemicals (EDCs), by 7 strains of industrial koji molds (Aspergillus oryzae) was studied. More than 50% of the biodegradation of BPA was apparent in a 6-days agar plate culture by using 5 strains of A. oryzae. The degradation of OP and NP proceeded relatively more easily than BPA. Most strains degraded more than 50% of OP and NP even with only 3 days of culture. The similar degradation of EDCs occurred in a surface-liquid culture. OP and NP were also degraded with A. oryzae KBN606 in koji-making used whole soybeans. These findings suggest the possibility that BPA, OP and NP may be degraded during the koji-making process in the production of traditional fermented foods, even if the ingredients and/or water were contaminated with these EDCs.
      In this study, we also found that OP and NP were easily degraded by the mycelia of A. oryzae KBN606. This fact suggests that the mycelia can be used to remove OP and NP contaminants as a bioremediation tool.

      The effects of light quality and environmental temperature on both the anthocyanin and rutin contents, and on the DPPH radical-scavenging activity of buckwheat (Fagopyrum esculentum Moench) sprouts were examined. Buckwheat sprouts were grown a length of 12 cm in darkness at 15, 25, and 35 ℃ . The sprouts were then irradiated with white (three-band fluorescent), blue, UV-A, and UV-B light for 24 hours at 15, 25, and 35℃, and compared with the sprouts grown in darkness. The results show that the highest levels of anthocyanin and rutin, and the highest radicalscavenging activity were found in the seedlings grown at 25℃ in UV-B light. The seedlings grown at 15℃ in UV-B light also exhibited increased contents of anthocyanin and rutin, and greater radical-scavenging activity than the sprouts grown in darkness, although the increases were smaller than in the sprouts grown at 25℃ . The UV-B light treatment at 35℃ increased the anthocyanin content but had no effect on the rutin content nor on the radical-scavenging ability. The optimal temperature of 25℃ with UV-B irradiation proved best for increasing the flavonoid production and radical-scavenging activity of this species.

      The present study examined family dinner conversations about positive and negative emotions over the course of four years (Time1 to Time4). The target family comprised a mother, a father, their sons aged five and nine, and their seven -year old daughter at Time1. The family was observed in two contexts: when the mother was present with her children (mother-child sessions, Time1 to Time4) and when both parents were present with their children (parent-child sessions, Time3 to Time4). Family discourse about negative emotions involved a greater variety of vocabulary over time, as opposed to that of positive emotions. At the same time, conversations between parents and children depended on the pragmatic context in which they occurred. Children discussed negative emotions more in mother-child sessions especially during their school period (Time3, 4). In a pragmatic context, although family members spoke more about positive and negative emotions when they spoke about “dinner (their preferences and manners)’’ in parent-child sessions, they spoke more about both emotions when they spoke about “everyday events’’ in mother-child sessions. The results highlight the significance of family discourse about negative emotions in school children’s emotional understanding.

      Mealtime surveys, food frequency questionnaires and quantitative ultrasound measurements of right calcareous bone were conducted from 2004 to 2006 on 280 female college students to investigate the effects of mealtime environment and food intake on bone mass. The data from this study show that students who had a good mealtime environment, such as family meals and at-home eating, ate more vegetables, fruits, meat and fish, while, students with a poor mealtime environment consumed more snack foods and soft drinks. Furthermore, those with the better mealtime environment and higher bone mass ate the most fish among all these students.
      These results indicate that the better mealtime environment might contribute to the quality of diet. It seems important to have a diet containing protein from a variety of sources during adolescence to achieve higher bone mass.

      This survey identifies the health conditions by dietary habits needing correction in high school students. Only 14.3% of the high school students had no dietary habits needing to be corrected. About 40% of the students had irregular mealtimes, and often had between-meal snacks and midnight snacks. A difference was found between the boys and girls in the dietary habits which should be corrected. The high school boys had such dietary habits as greasy meals and eating alone, while the high school girls tended to diet and generate leftover food. Those high school students having many dietary habits needing correction generally also had poor health.
