      • IFGT 의 실증적인 lower bound 에 관한 분석

        김경옥,이재욱 대한산업공학회 2010 대한산업공학회 춘계학술대회논문집 Vol.2010 No.6

        지난 몇 십 년간 저장되고 있는 정보량은 폭발적으로 증가하였다. 이와 함께 빠르고 효과적으로 이들을 분석하는 알고리즘의 필요성이 같이 증가하고 있다. 하지만 지금까지 개발된 커널머신은 사용하는 데이터의 수가 증가하면 매우 많은 계산 비용을 요하여 대용량 데이터에 적용하기에 어려움이 따른다. 이 점을 개선하기 위해 개발된 IFGT 는 계산 시간이 O(MN)이 아니라 O(N+M)을 따라 증가하기 때문에 대용량 데이터를 상대적으로 빠르게 처리할 수 있다. 본 발표에서는 데이터의 차원과 개수에 따른 IFGT 계산 시간의 lower bound 를 실증적으로 알아보고 다른 방법과 비교하여 데이터의 특성에 따라 어느 방법으로 계산하는 것이 적합한지 제시하고자 한다.

        Immunomodulatory Effects of High-Protein Diet with Resveratrol Supplementation on Radiation-Induced Acute-Phase Inflammation in Rats

        김경옥,박현진,전미선,김현숙 한국식품영양과학회 2014 Journal of medicinal food Vol.17 No.9

        We hypothesized that a high-protein diet and/or resveratrol supplementation will improve acute inflammatory responses in rats after receiving experimental abdominal radiation treatment (ART). Based on our previous study, the period of 10 days after ART was used as an acute inflammation model. Rats were exposed to a radiation dose of 17.5Gy and were supplied with a control (C), 30% high-protein diet (HP), resveratrol supplementation (RES), or HP with RES diet ([HP + RES]). At day 10 after ART, we measured profiles of lipids, proteins, and immune cells in blood. The levels of clusters of differentiating 4+ (CD4+ ) cells and regulatory T cells, serum proinflammatory cytokines, and 8-hydroxy-20-deoxyguanosine (8-OHdG) in urine were also measured. ART caused significant disturbances of lipid profiles by increasing triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C), and decreasing high-density lipoprotein cholesterol. The proinflammatroy cytokine levels were also increased by ART. All the experimental diets (HP, RES, and [HP + RES]) significantly decreased levels of TG, monocytes, proinflammatory cytokines, and 8-OHdG, whereas the platelet counts were increased. In addition, the HP and [HP + RES] diets decreased the concentrations of plasma LDL-C and total cholesterol. Also, the HP and RES diets decreased regulatory T cells compared with those of the control diet inARTgroup. Further, theHPdiet led to a significant recovery of white blood cell counts, as well as increased percentages of lymphocyte and decreased percentages of neutrophils. In summary, RES appeared to be significantly effective in minimizing radiation-induced damage to lipid metabolism and immune responses. Our study also demonstrated the importance of dietary protein intake in recovering from acute inflammation by radiation.

The purpose of this study is to survey the need for parental education of the mothers of married immigrant families with young children and how it varies depending on country of origin, length of stay in Korea and monthly average income. To achieve the purposes as above, this study was carried out on the following research questions.1. What is the need for parental education of the mothers of married immigrant families with young children?2. How does the need for parental education of the mothers of married immigrant families with young children vary depending on variables?2-1. How does the need for parental education of the mothers of married immigrant families with young children vary depending on their country of origin?2-2. How does the need for parental education of the mothers of married immigrant families with young children vary depending on the length of stay in Korea?2-3. How does the need for parental education of the mothers of married immigrant families with young children vary depending on monthly average income?The subjects of this study are 123 mothers of married immigrant families with 3-5-year-old children going to the public․private kindergartens located in 17 cities and counties across Gangwon-do. Their countries of origin include China, the Philippines, Vietnam and Japan. As for a research tool, a questionnaire form ‘Need for Parental education’ made by Yoon, So-Young (2002) was modified and supplemented on the basis of the results of interviews with subjects for the purpose of this study. As for data processing, to find out the need for parental education of the mothers of married immigrant families with young children, frequency and percentage were calculated. Furthermore, to analyze the need for parental education of the mothers of married immigrant families with young children according to variables(country of origin, length of stay in Korea and monthly average income),  test was conducted. The results of this study can be summarized as follows. First, the need for parental education of the mothers of married immigrant families with young children was examined and as a result, the need for parental education of the mothers of married immigrant families with children is high in the following categories; how to take measures in emergency situations and safety accidents, knowledge on child nutrition and how to let children have proper eating habit in the category of child health and raising; information on brain development of children in the category of children development; how to effectively communicate with children in the category of communication between parents and children; how to correct the maladaptive behavior of children in the category of child habit formation; and information on married immigrant family support and how to use it in the category of mothers’ adaptation to Korea. Second, the need for parental education of the mothers of married immigrant families with young children depending on the variables - country of origin, length of stay in Korea and monthly average income - was examined. Based on the results, the following conclusions have been derived. 1. The need for parental education according to country of origin was examined by category and as a result, there are significant differences in how to correct the maladaptive behavior of children in the category of child habit formation; and Korean education for mothers, Korean culture eduction for mothers, information on how to relieve stress for mothers, education on understanding of family relationship in Korea in the category of mothers’ adaptation to Korea. Regarding how to correct the maladaptive behavior of children in the category of child habit formation, the need for parental education of the mothers from China and the Philippines turned out to be relatively higher than that of the mothers from Japan and Vietnam. Regarding Korean education for mothers in the category of mothers’ adaptation to Korea, the need for parental education of the mothers from Vietnam, the Philippines and Japan turned out to be relatively higher than that of the mothers from China. Regarding Korean culture education for mothers and education on understanding of family relationship in Korea, the need for parental education of the mothers from Vietnam and the Philippines turned out to be relatively higher than that of the mothers from China and Japan. Regarding information on how to relieve stress for mothers, the need for parental education of the mothers from Vietnam, the Philippines and Japan turned out to be relatively higher than that of the mothers from China.2. The need for parental education according to the length of stay in Korea was examined by category and as a result, there are significant differences in how to check children’s health and care for sick children, how to take measures in emergency situations and safety accidents of children, knowledge on child nutrition and how to let children have proper eating habit in the category of child raising and health; in Korean education for mothers in the category of mothers’ adaptation to Korea. Regarding how to check children’s health and care for sick children, how to take measures in emergency situations and safety accidents of children, knowledge on child nutrition and how to let children have proper eating habit in the category of child raising and health, the need for parental education of the mothers who stayed in Korea less than 6 years turned out to be relatively higher than those who stayed for more than 6 years to less than 9 years and those who stayed more than 9 years. Regarding Korean education for mothers in the category of mothers’ adaptation to Korea, the need for parental education of the mothers who stayed in Korea less than 6 years turned out to be relatively higher than those who stayed for more than 6 years to less than 9 years and those who stayed more than 9 years.3.
