  • The purpose of this study was to obtain data on the child care support and job satisfaction of married women employed outside home. The data for this study were collected from a survey of 350 married women employed outside home who were residing in North Cholla Province. Major fimding are summarized in the following. First, many married women were pressured by the burdens child rearing(54.5%) and houshold chores(39.6%). Second, the daycare arrangements for children under age seven were diverse. Just under half of the children were cared for by the employed mother'parents(25.1%), or by the mother's parents-in law(21.1%). The rest were sent to daycare center(40.6%), cared for by a hired helper(7.6%), or sent to an industrial on- site daycare center(1.0%). Third, about half of the married employed mothers(47.5%) wished for an on-site daycare service at their workplace. Fourth, the variables that affected employed mothers job satisfaction were age, job, husband's job type, the income of the mother, the reason of the mother's employment, the degree of husband's houshold labor participation, and the type of social and employer's support for chid care.

  • Female ICR mice were vaccinated against Toxoplasma gondii(RH strain), infected 2 weeks later and after recovery mated to normal ICR males. Control matings were with normal ICR females. The progeny of the above matings were weaned at 1 week, vaccinated at 1, 2, 3, 4 or 5 weeks of age and infected 2 weeks later with lethal Toxoplasma tachyzoites. As assessed by survival, the effectiveness of vaccination among offspring of vaccinated-recovered mothers was greatly impaired than that of control mice, with respective of age : where mice did survive, recovery was greatly delayed relative to the controls. The protective effect of vaccination among infants born to control mothers was also blocked by maternal specific antibodies, by administration of high-titered specific antibodies or by transfer of nylon wool adherent immune-spleen cells, but was augmented by transfer of nylon wool passed immune-spleen cells. These results indicate that this impairment of vaccination may be due to the transmission of maternal specific antibodies to the offspring which acts to suppress both priming by the vaccine and the generation of parasite-specific helper T cells.

  • Animals are one of the important memberships of the food chain. The low-efficiency rule of nutrient transfer from one member to the next in the food chain determines the low efficiency of animal agriculture for human food. On the average, about 20% feed proteins and 15% feed energy can be converted into edible nutrients for humans. The rest proportion of feed nutrients is exposed to the environment. Environmental pollution, therefore, is inevitable as animal agriculture grows intensively and extensively. The over-loading of the environment by nutrients such as nitrogen, phosphorus from animal manure results in soil and water spoilage. The emission of gases like $CH_2$, $CO_2$, $SO_2$, NO, $NO_2$ by animals are one of the contributors for the acidification of the environment and global warming. The inefficient utilization of natural resources and the probable unsafety of animal products to human health are also a critical environmental issue. Improving the conversion efficiency of nutrients in the food chain is the fundamental strategy for solving environmental issues. Specifically in animal agriculture, the strategy includes the improvements of animal genotypes, nutritional and feeding management, animal health, housing systems and waste disposal programs. Animal nutrition science plays a unique and irreplaceable role in the control of nutrient input and output in either products or wastes. Several nutritional methods are proved to be effective in alleviating environmental pollution. A lot of nutritional issues, however, remain to be further researched for the science of animal nutrition to be a strong helper for sustainability of animal agriculture.

  • Atopic dermatitis (AD) is an immune disorder that is becoming increasingly prevalent throughout the world. The exact etiology of AD remains unknown, and a cure for AD is not currently available. The hypothesis that appropriate early microbial stimulation contributes to the establishment of a balanced immune system in terms of T helper type Th1, Th2, and regulatory T cell (Treg) responses has led to the use of probiotics for the prevention and treatment of AD in light of various human clinical studies and animal experiments. Meta-analysis data suggests that probiotics can alleviate the symptoms of AD in infants. The effects of balancing Th1/Th2 immunity and enhancing Treg activity via the interaction of probiotics with dendritic cells have been described in vitro and in animal models, although such an effect has not been demonstrated in human studies. In this review, we present some highlights of the immunomodulatory effects of probiotics in humans and animal studies with regard to their effects on the prevention of AD.

  • Purpose: Professional quality of life is the quality one feels in relation to their work as a helper. The purpose of this study was to describe professional quality of life among emergency nurses. Methods: A total of 15 emergency rooms were selected in three cities. Among 263 nurses working at these emergency rooms, 178 nurses consented to participate in this cross-sectional survey. Professional Quality of Life (ProQOL) Scale version 5 was used to measure compassion satisfaction, burnout and secondary traumatic stress. Cluster analysis was used to classify nurses according to professional quality of life. Results: The mean scores (SD) for compassion satisfaction, burnout, and secondary traumatic stress were 32.12 (5.45), 28.27 (4.28), and 28.20 (5.07), respectively. The result of cluster analysis according to standardized score of compassion satisfaction, burnout, and secondary traumatic stress yielded three clusters. Over 50% of participants showed low professional quality of life. Nurses who were included in a cluster representing low professional quality of life were younger, had shorter periods of nursing experience, and perceivedlower social support than other cluster. Conclusion: Education or support programs for emergency nurses are needed to enhance their professional quality of life.

  • This study was designed to examine the effect of icroencapsulated iron fortified drink yogurt and vitamin C as a bioavailable helper of iron on chemical and sensory aspects during 20 d storage. Coating material was polyglycerol monostearate (PGMS), and ferric ammonium sulfate and vit C were selected as core materials. The highest efficiency of microencapsulation of iron and vit C were 73% and 95%, respectively, with 5:1:50 ratio (w/w/v) as coating to core material to distilled water. Iron fortification did not affect the fermentation time required for the drink yogurt to reach pH 4.2. The addition of uncapsulated iron decreased the pH during storage. TBA absorbance was significantly lower in capsulated treatments than in uncapsulated treatments during storage. In sensory aspect, the yogurt sample added with uncapsulated iron and vit C, regardless of capsulation, showed a significantly high score of astringency, compared with those of control and other groups. A significantly strong sourness was observed in treatment containing capsulated iron and uncapsulated vitamin C at every time interval. The present study provides evidence that microencapsulation of iron with PGMS is effective for iron fortification in drink yogurt.
