It is yet to be understood what controls the star formation activity in high-redshift galaxy clusters. One recently proposed mechanism is that the star formation activity in galaxy clusters are fed by gas and galaxies in large-scale structures surrounding them, which we call as "web feeding model". Using galaxies in the COSMOS2015 catalog, with mass completeness at log(M/M⦿)≥9.54 and reliable photometric redshift data (σΔz/(1+z) ≲ 0.01), we study the star formation activities of galaxy clusters and their surrounding environment to test the web feeding model. We first identify the overdense regions with number density exceeding the 4σ-level from photometric redshift data as galaxy clusters, and we find that they are well matched with clusters identified in the X-ray extended source catalog. Furthermore, we identify galaxy large scale structures, and will present the correlation or anti-correlation between quiescent galaxy fraction, an indicator of star-forming activity, and the prevalence of galaxy large scale structures.
In order to obtain baseline data for the development of an educational program on breastfeeding, a survey was carried out to investigate infant feeding practices, the characteristics the subjects have in common, and the factors that influence the feeding methods among women in Seoul and the Chungbuk area. Subjects included 671 lactating mothers who visited public health centers or pediatric clinics between December 1999 and February 2000, and were interviewed using a questionnaire. The results were as follows : With respect to feeding methods, the incidence of breastfeeding, formula feeding, mixed feeding and formula feeding switched from breastfeeding was 20.6%, 29.8%, 11.6%, and 38.0%, respectively. With respect to the characteristics the subjects had in common, the incidence of women who planned their infants' feeding methods before pregnancy, during pregancy, and after delivery was 48.7%, 31.0%, and 20.3%, respectively. The incidence of women who started breastfeeding in the hospital after delivery was 38.8%. About seventy seven percet of the subjects had not previously attended an educational program on breastfeeding, and most of these wanted to participate in the future in an educational program to learn about breastfeeding. Some of the topics they were interested in were“Nutritional Management for Sufficient Breast Milk”(60.3%),“Breast Care”(25.0%), and“Correct Nursing Positions”(9.8%). Most (88.2%) of the women who breastfeed suffered from physical discomforts including discomfort of the waist, and legs and discomfort due to cracked or sore nipples. “Insufficient breast milk”was the main reason for breastfeeding cessation or for switching to formula feeding. With respect to formula feeding practices, the main reasons for selecting a specific brand of formula were“the same brand the hospital used after delivery”(34.3%) and“an advertised brand”(23.3%). The strongest factor for promoting breastfeeding was“the support of husband or parents”, next were “breastfeeding in the hospital after delivery”and“planning to breastfeed before pregnancy”in that order. The characteristics the subjects had in common relating to formula feeding were“mother's job”,“high economic level”,“Caesarian section”and “planning to breastfeed after delivery”. In conclusion, it is recommended that breastfeeding be pro-moted, and educational programs be developed and offered as soon as possible to each group which had unfavorable attitudes toward breastfeeding. In addition, the monitoring and supervision of formula advertisements is required to protect consumers from the adverse effects of exaggerated advertising.
Purpose: The purpose of this study was to evaluate middle school students' knowledge and attitudes related to breast feeding. Methods: The knowledge and attitudes related to breast feeding were measured by structured questionnaires. Data were analyzed by descriptive statistics, t-test, one-way ANOVA, and Pearson correlation, using the SPSS/WIN 17.0 program. Results: The level of knowledge of breast feeding was 9.02 points out of 25 points, in average. Attitudes towards breast feeding was 3.77 points out of 5 points, in average. There were significant differences in the knowledge of breast feeding according to grade, feeding type, family type, experiences of observing breast feeding, experiences of obtaining breast feeding information, will to practice breast feeding, and the reasons for low breast feeding rate. There were significant differences in attitudes towards breast feeding according to gender, grade, feeding type, family type, experiences of observing breast feeding, experiences of obtaining breast feeding information, timing of breast feeding education, will to practice breast feeding, and the reasons for low breast feeding rate. There was a significant positive correlation between the knowledge of breast feeding and attitudes towards breast feeding. Conclusion: Middle school students should be provided with various education programs to improve their knowledge of and attitudes toward breast feeding.
Objectives: The purpose of the study was to develop dietary change program items that could be used to improve dietary life of the elderly and investigate their validity. Methods: The survey was were analyzed by SPSS program (Ver. 21) and descriptive statistics was performed; a t-test, ${\chi}^2$ test, One-way ANOVA and Friedman test were used to determine the priority. Results: Programs for feeding senior citizens that need to be newly established are largely divided into two fields, namely, application of welfare facilities and application of home care, classified into large, medium and sub-classes. The large class was divided into nutrition management, sanitary control, and other health management. The medium class of nutrition management was divided into nutrition education, nutrition intervention, and menu management and supply. The sub-class was composed of division into application of welfare facilities for the elderly and application of home care for the same age group. Responses showed high rate saying that all the categorized items were necessary and valid. With respect to expectation effect on a community program for old people feeding, 'yes' was 65 people (55.6%) showing very high expectation toward the question whether a community program for old people feeding are newly set up. Conclusions: It is believed that nutrition for the aged will be improved and it will be a help not only to a small facilities without obligation of employing a dietician but also to the aged at home if a community program for old people feeding are newly established.
The process of breast feeding was investigated from the 36th week of pregnancy to 12 weeks postnatal, in order to analyze the factors affecting breast feeding duration and provide the basic data on an education program for successful breast feeding. The general characteristics of study group had no marked effects on the breastfeeding duration. The young and highly condition during pregnancy and the degree of morning sickness affected the practice of breastfeeding. In the study of prenatal sociobehavioral factors, intended duration affected the breastfeeding duration, and the maternal perception that breastfeeding is good for weight loss after delivery as well as infant formula milk is not as good as breast milk, led to successful breast feeding. Among the postnatal biological factors, the duration of gestation affected the breast feeding. Among the postnatal biological factors, the duration of gestation affected the breastiffeding outcome. In the case of early parturition, breastfeeding rate was low. Among the postnatal biocultural factors, time of first feed, milk volume and maternal perception of infant's sucking ability affected the bresatfeeding duration. From these result, it is suggested that an education program such as participation of nursing class to the pregnant women should be provided for successful breastfeeding.
A communal feeding program has been managed mostly by the Sae Ma Eul Women's club of agricultural cooperatives during busy days of farming in rural Korea and spreading rapidly throughout the country since a couple of years ago. Four communal feeding villages from 3 provinces in Korea were purposively selected. The food and nutrient intake of 524 participants were measured by the Precise-Weighing method for 3 days from October $7{\sim}16$ 1976. Total amount of food consumed per participant per two meal day was 1456 grams, greater than national average. Two meals that the communal feeding program provided to farmers under the intensive work of harvesting were supplying enough calories and all other nutrients except the riboflavin. There was a variation among CF villages but overall the nutrient intake was good and had balanced meals. This investigation is a part of the study on nutrition supported by a grant from USAID.
This descriptive study was done to investigate the proportion of mothers breast feeding and identify factors which influence breast feeding. The subjects were 320 mother who child under five years of age, living in WonJu and their children who numbered 530. Data collection was conducted at various places in the WonJu area using survey questionnaire. The results were as follows : 1. The proportion of children receiving breast feeding was 23.3%, mixed feeding 31.7%, milk feeding 45.1%. The most frequent duration for breast feeding was one month, the mean duration was six months. 2. The major reasons for breast feeding were for the health of the child 52.5%, for emotional attachment with the child 34.2%, and as the expected way of feeding 29.5%. 3. The major reasons for interrupting breast feeding were jobs 26.1%, illness of the child or mother 16.1% abnormality of the breast of nipple 12.7% others 31%. 4. The major reasons for quitting breast feeding were insufficient breast milk 34.5%, job 19.6%, diarrhea in the child 9.9%. 5. The factors influencing breast feeding were educational status and the presence of a job. 6. The husband's attitude to breast feeding was very positive 82.3% and the subjects were supported by their mothers and husbands. But the major information sources about breast feeding were the mass media 30.4% and relatives 22.0%. 7. The breast feeding mother reported experiencing positive and satisfactory feelings, but the milk feeding mother reported experiencing negative and guilt feelings. Also the breast feeding mothers perceived their children as very healthy with a stable emotional status. The results showed the breast feeding ratio in WonJu to be very low and problematic and the subject mothers strongly need information about breast feeding and support while breast feeding. Therefore it is recommended that an education program for community women and other people, like husbands, and grandmothers, be developed along with an education program for university students and other young people to provide them with preparatory information as they begin to think about marriage and families.
To evaluate the effect of the feeding program of brown rice flake with soy milk or cow's milk to school children in rural areas. The survey was conducted twice before and after practice of feeding in March and July of 1990. The survey covered a total of 87 children aged from 7 to 12 in Ypsuk elementary school located in remote village of Sangju county. Kyung Buk province and the branch school of Songmyun elementary school located in remote village of Goisan county. Chung Buk province. Family environment dietary intake anthropometric data and biochemical tests were examined. The results are summerized as follows: The mean balance and food diversity at lunch were significantly lower than those at breakfast and dinner. Mean daily energy and nutrient intakes were below the Korean RDA's except for intakes of niacin vitamin A and ascorbic acid Especially intake of calcium was not reached to 50% of Korean RDA's. Most of anthropometric data of subjects surveyed showed slightly higher results in summer than those in spring except for weight for height and sitting height for height. The percentage of anemic according to hematocrit criterion was not reduced during this period. however urinary urea nitrogen/creatinine ratio was improved. The conbined feeding program of brown rice flake with soy milk or cow's milk was not sufficient to support the children's growth. So the survey recommends the support of goberment to the school lunch program in the remote village.
Purpose: This study aimed to evaluate a pilot project of the Nursing Feeding Center "Posyandu Plus" (NFCPP) through local food-based complementary feeding (LFCF) program designed to improve the nutritional status of children aged 6-36 months at community health centers in Indonesia. Methods: A quasi-experimental design was used to obtain data regarding the nutritional status of 109 children who participated in the project from 6 rural areas. The NFCPP was conducted for 9 weeks, comprising 2 weeks of preintervention, 6 weeks of intervention, and one week of postintervention. The LFCF intervention consisted of 12 sets of recipes to be made by mothers and given to their children 4 times daily over 6 weeks. The weight-for-age z score (WAZ), height-for-age z score (HAZ), weight-for-height z score (WHZ), and body mass index-for-age z score (BAZ) were calculated using World Health Organization Anthro Plus version 1.0.3. Results: LFCF intervention significantly increased WHZ, WAZ, and BAZ scores but decreased HAZ scores (P<0.001). Average scores of WHZ ($0.96{\pm}0.97$) and WAZ ($0.45{\pm}0.72$) increased; BAZ increased ($1.12{\pm}0.93$) after 6 weeks of LFCF. WAZ scores postintervention were 50.5% of normal, and WHZ scores were 77.1% of normal. However, the HAZ score decreased by $0.53{\pm}0.52$, which indicated 57.8% had short stature. Conclusion: The NFCPP program with LFCF intervention can improve the nutritional status of children in rural areas. It should be implemented as a sustained program for better provision of complementary feeding during the period of lactation using local food made available at community health centers.
We studied the influence certain environmental factors (proximity of roosting site, roads, and residential areas) have on the spatial distribution of cranes in the Cheorwon, Korea. Using a range finder and GPS, data were collected from January to February 2007 and were subsequently evaluated with ArcGIS. The size of the cranes' wintering habitat was estimated to be 7$76.9km^2$. Five hundred and fifty-five flocks of cranes were observed and detailed distributions were collected. Feeding distribution of the cranes showed clustered distribution, however, no tendencies of spatial autocorrelation were apparent. Adjacent regions with paved roads and residences showed lower densities than other areas. Distances at which paved roads and residential areas induced changes in feeding flock densities were 1500m and 1750m, respectively. Feeding flock density decreased with increased distance from roosting site. Feeding flock density of the two crane species did not increase as distance from roads increased, however, the density of individuals showed a significant increasing tendency with increased distance from roads. In both species, density of feeding flocks and individuals significantly increased with increasing distance from residential areas. In Red-crowned Cranes, the density of feeding flocks and individuals significantly decreased with increasing distance from roosting site, however, in the case of White-naped Cranes, there was an even distribution in density of feeding flocks and individuals.
