The number of Healthy Family Support Centers has dramatically increased during the past eight years since the Framework Act on Healthy Families was enacted. This phenomenal growth is largely credited to Certified Healthy Family Specialists (CHFSs). Despite their contributions, the job and working conditions of the CHFSs have rarely been explored from the insiders' perspective. In this study, we aim to delineate CHFSs' job and working conditions from their own narratives in order to improve an understanding of CHFSs' profession and work environment. We conducted in-depth interviews with nine CHFSs and a focus-group interview with five CHFSs. Our findings revealed that CHFSs took pride in their professions, internalized their professional mission of enhancing family strengths, and highlighted CHFSs' unique professional role in comparison to other human services professionals. In conclusion, CHFSs showed a strong professional identity consisting of rich professional knowledge, solid career goals, and integrated socio-political values. Contrary to the positive perception of the CHFSs' job, CHFSs expressed challenges in their working conditions in terms of small-scale organizations at local Healthy Family Support Centers, a heavy workload, hierarchical relationships with local government officers, and the unsatisfactory payroll and promotion system. This study contributes to a better understanding of CHFSs' job and their working conditions and provides insights on how to enhance professionalism among CHFSs and their work environment. As for policy implications, we suggest advancing qualifications for CHFSs, improving professional training programs for current CHFSs, and expanding small-scale organizations.

Onto the world-fastest ageing of society, the world-lowest fertility rate prompted a development of various policies and programs for a betterment of the population in Korea. Since the vulnerability of young children of low socio-economic class to malnutrition was clearly shown at the in-depth analysis of the 2001 Korea National Health and Nutrition Examination Survey data, an effort to devise supplemental nutrition care program for pregnant/breastfeeding women, infants and preschool children was initiated. The program was designed to offer nutrition education tailored to fit the needs of the participants and special supplementary foods, using USDA WIC program as a benchmark. Based on the dietary intake of those age groups, target nutrients were selected and their major food sources were searched through nutrient content of foods and dietary pattern analysis. As a result, we developed 6 kinds of food packages using combinations of 11 different food items. The amount of each item in a food package was determined to supplement the intake deficit in target nutrients. Nutrition education in $NutriPlus^+$ aims to improve the nutrition knowledge, attitude, and dietary behaviors of the participants, and is provided through group lessons, individual counseling sessions and home visits. Breastfeeding is promoted with top priority in education for the health of both mother and baby. The eligibility guidelines were set for residency, household income, age, pregnancy/breastfeeding and nutritional risk such as anemia, stunting, underweight, and/or inadequate nutrient intake. Income eligibility was defined as household income less than 200 percent of the Korean poverty guidelines. A pilot study to examine the feasibility of program implementation was run in 3 public health centers in 2005 and expanded to 15 and 20 in the following 2 years. The result of 3-year pilot study will be reported separately along with the ultimate nationwide implementation of the $NutriPlus^+$ in 2008.

Premature ovarian failure (POF) is a long-term adverse effect of chemotherapy treatment. However, current available treatment regimens are not optimal. Emerging evidence suggests that bone marrow-derived mesenchymal stem cells (BMSCs) could restore the structure and function of injured tissues, but the homing and restorative effects of BMSCs on chemotherapy injured ovaries are still not clear. In this study, we found that granulosa cell (GC) apoptosis induced by cisplatin was reduced when BMSCs were migrated to granulosa cells (GCs) in vitro. Chemotherapy-induced POF was induced by intraperitoneal injection of cisplatin in rats. BMSCs labeled with enhanced green fluorescent protein (EGFP) were injected into the rats via the tail vein to investigate the homing and distribution of BMSCs in vivo. The number of BMSCs in the ovarian hilum and medulla was greater than in the cortex, but no BMSCs were found in the follicles and corpus lutea. In addition, the BMSCs treatment group's antral follicle count and estradiol levels increased after 30 days, compared with the POF group. Hence, our study demonstrates that intravenously delivered BMSCs can home to the ovaries, and restore its structure and function in POF model rats.

마늘장아찌를 담글때 껍질의 유무와 염화칼슘의 첨가가 텍스쳐의 변화에 어떤 영향을 미치는지 조사하였다. 알코올 불용성 고형물(AIS)은 숙성에 따라 모든 시료군에서 점차 감소하는 경향이었다. AIS의 감소율은 염화칼슘을 첨가한 마늘에서 더 적었다. 펙틴질에 있어서는, 모든 시료군이 숙성에 따라 염산 가용성 펙틴은 소량 감소하였으며, 메타인산 가용성 펙틴은 크게 증가하였고, 총펙틴질과 열수 가용성 펙틴은 거의 변하지 않았다. 염화칼슘을 첨가한 마늘이 첨가하지 않은 마늘보다 염산 가용성 펙틴의 보존율이 높고 메타인산 가용성 펙틴의 증가율은 더 낮았다. Instron에 의한 경도는 통마늘이 깐마늘보다 약간 더 높았고 염화칼슘을 첨가한 마늘이 첨가하지 않은 마늘보다 더 높았으며, 숙성에 따라 모든 시료군에서 점차 감소하였다.

This study examined social integration policies for multi-cultural families in Korea and the United States through a literature review and internet research. Because the United States has developed and maintained its own culture, this was an appropriate country to compare to Korea in terms of social integration policy. There were four main results. First, both countries enforce assimilation policies for multi-cultural families. Second, most social integration programs and services for multi-cultural families in Korea are carried out by the Multi-cultural Family Support Centers, which are supported by the national and local governments in Korea. However, because the U.S. government has preserved a laissez-faire approach to policies for immigrant families, there are no government-based support centers for multi-cultural families in the United States. Third, both countries focus on the assimilation of multi-cultural families. Nevertheless, the U.S. government promotes a balance between ethnic identity and U.S. citizenship. Fourth, the U.S. government strongly supports second-generation education and development programs that recognize the second generation as a human resource for the future of society. In summary, even though there were some cultural differences between the two countries, the United States' assimilation policies based on ethnic identity would be useful for Korean integration policies. In addition, it is very important to offer opportunities for mutual integration in everyday life between Korean families and multi-cultural families.

This experiment was conducted to examine the effects of fish oil supplementation with low does on the lipid concentration and fatty acid composition of plasma and the fatty acid composition of plasma phospholipid and erythrocyte of infants. Among 18 breast-fed infants, 6 were in control group and 12 were in fish oil groups. The subjects in fish oil groups were nursed by their mothers who supplemented with fish oil 1.96g/d or 3.92g/d, respectively for 2 weeks from 10 to 12 weeks postpartum. The nursing mothers consumed their usual diets at home. Blood samples were collected at the final day of experiment. There were no significant changes in daily intakes of total lipid, triglyceride, free fatty acid, phospholipid and cholesterol of infants by fish oil supplementation. However, the content of EPA (eicosapentaenoic acid)increased and that of ARA (arachidonic acid) decreaed significantly in plasma PC(phophatidylchline). And also, there were tendencies to increase triglyceride concentration and to decrease cholesterol and phopholipid concentrations of plasma. As the above results, atherogenic index (AI) showed a tendency to decrease, but not significant. DHA (docosahexaenoic acid) and EPA contents in plasma PC and PE (phosphatidylethanolamin) as well as those of erythrocyte tended to increase. In these results, we concluded that fish oil supplementation with low dose to lactating women does not obviously affect of the plasma lipid concentrations and fatty acid composition of plasma PC and PE as well as erythrocyte. However the increase of EPA content of plasma PC and the tendency to increase DHA and EPA contents of plasma as well as erythrocyte membrane indicate that there may be some beneficial effect on infant lipid metabolism of fish oil intake of nutsing mother were increased.

We studied the effects of fish oil supplementation with low does on the lipid concentration and fatty acid of plasma and the fatty acid composition of plasma phospholipid and erythrocyte of lactating women. The subjects, 18 lactating women, who were exclusively breast-fed their babies were classifed into a control group and 2 fish oil groups according to dose; the subjects of fish oil groups were supplemented with 1.96g/d or 3.92g/d of fish oil, respectively for 2 weeks from 10 to 12 weeks postpartum. All subjects consumed their usual diet at home. Blood sample were collected at the final day of experiment. The plasma HDL-cholesterol level increased significantly by fish oil supplementation. The concentrations of DHA (docesahexaenoic acid) and EPA (eicosapentaenoic acid) in the plasma PC(phosphatidylcholine) and PE (phosphatidylethanolamine)of fish oil groups tended to increase, but not significant. However, the concentrations of DHA and EPA of PC and PE in erythrocyte were not affected by fish oil supplementation. These results demonstrate that fish oil supplementation with low dose does not change the concentration of plasma lipid as well as fatty acid composition in plasma PC and PE and red blood cell obviously. However the increase of plasma HDL-cholesterol level, the reduction of atherogenic index(AI) and the tendency of increase of DHA and EPA concentrations in plasma PC and PE indicate that there may be some beneficial effects on maternal lipid metabolism if fish oil intakes were increased.
