Purpose: Feeding problems are common for typically developing children and have negative effects on physical, behavioral, and cognitive development. The purpose of the current study was to examine factors related to childhood feeding problems for typically developing children via parental reports. Methods: The feeding questionnaire developed by the authors and the Childhood Eating Behavior Inventory (CEBI) were administered to 796 parents of children who recruited from 2 pediatric outpatient clinics (n=379) and community (n=417). Problem eaters (PE) were identified by parental report and frequency analysis was conducted for types of feeding problems and its severity, problem behaviors during mealtime, the feeding methods of the parents, and the need for treatment. Results: The CEBI scores were significantly different between the PE and non-problem eaters (NPE), which suggests that the parental reports were reliable. The younger children had more feeding problems than the older children. The most frequent and severe feeding problems were selective eating and longer mealtimes across all age groups. One-half of the children had more than one problem behaviors during mealtime. Most parents of PE used ineffective methods to deal with children's behaviors during meal time, such as cajoling, which was related to their increased level of stress. Many parents reported their children need professional help for the feeding problems. Conclusion: Feeding problems are prevalent among children, especially younger children. Children with feeding problems showed a number of problem behaviors during mealtime and parental coping methods appeared to be ineffective. The need for treatment was considerable, thus the characteristics of this population must be acknowledged for providing proper treatment and advice.

The purpose of this study was to investigate the eating behavior and life habits of kindergarten children 5 to 7 years old in Chuncheon area. This study was conducted in December, 1996. Anthropometric indices(height, weight, skinfold thickness, mid-arm circumference) were measured and body mass index(BMI), Rohrer index, arm fat area were calculated to estimate children’s body fatness. Also the eating behavior and life habits were determined tv using questionnaire method. The results were as follows: Body fat rate of the children was almost normal according to Rohrer index and BMI. There was significant difference in birth weight between male and female. The problems of the eating behavior were frequent skipping breakfast and eating-out. The rate of the children who took snacks 2 times a day was 46.9％. Most children tended to take sweet snacks such as ice-cream, chocolates, cookies, and they tended to prefer meats and fishes to vegetables. The rate of breast feeding was 28.3％ and the rate of weaning foods prepared at home was 61.1%. Many children preferred indoor activities such as watching TV, toy furniture play, building block to outdoor activities such as roller-skating, cycling, jogging in their spare time. The rate of the children who took exercise regularly was 15％. Children tended to eat kimbap, fried chicken, ramyeon more frequently in various instant foods. The intake rates of fruit juice and barly tea were relatively high and children's favorite fruits were watermelon and mandarin orange. From this results, skipping breakfast, frequent eating-out and the monotony of food preference appears to cause imbalance in nutrient intakes of the children and to have bad influence on children’s health. Accodgingiy, the comprehensive nutrition education and proper modification program should be needed for the children and their parents to correct the eating behavior and life habits. The reasonable exercise programs are needed to motivate outdoor activities of the children, and the importance of breast feeding and weaning foods should be emphasized to lactating women and pregnant women.

To investigate feeding behaviour of the greenpeach aphid (Myzus persicae) on several plants, DC electrical penetration graph (EPG) technique was used. We chose 5 plants including pepper, melon, cabbage, radish, and eggplant which were known as major host Plants of this species. This study was focused whether feeding patterns of the aphid were different and which plants would be the most preferable among 5 host plants. The time from initial proboscis contact with a each leaf until the first electrical contact, as a measure of the time taken for the stylet penetration, the time from electrical contact to the first potential drop as a time consumed until intracellular sampling, the number of potential drops per an hour during periods of regular intercellular pathway probing, and the time from electrical contact to tile first phloem specific pattern indicating the time taken to reach and attempt to feed upon the phloem were analysed. As a result, except the number of potential drop, there was no significant differency of feeding patterns among 5 plants. However, the feeding patterns related on host acceptability were observed more frequently from Pepper, radish, and e99r1an1 than melon and cabbage.

Recently, the heterotrophic nanoflagellate Katablepharis japonica has been reported to feed on diverse red-tide species and contribute to the decline of red tides. However, if there are effective predators feeding on K. japonica, its effect on red tide dynamics may be reduced. To investigate potential effective protist predators of K. japonica, feeding by the engulfment-feeding heterotrophic dinoflagellates (HTDs) Oxyrrhis marina, Gyrodinium dominans, Gyrodinium moestrupii, Polykrikos kofoidii, and Noctiluca scintillans, the peduncle-feeding HTDs Luciella masanensis and Pfiesteria piscicida, the pallium-feeding HTD Oblea rotunda, and the naked ciliates Strombidium sp. (approximately $20{\mu}m$ in cell length), Pelagostrobilidium sp., and Miamiensis sp. on K. japonica was explored. We found that none of these heterotrophic protists fed on actively swimming cells of K. japonica. However, O. marina, G. dominans, L. masanensis, and P. piscicida were able to feed on heat-killed K. japonica. Thus, actively swimming behavior of K. japonica may affect feeding by these heterotrophic protists on K. japonica. To the contrary, K. japonica was able to feed on O. marina, P. kofoidii, O. rotunda, Miamiensis sp., Pelagostrobilidium sp., and Strombidium sp. However, the specific growth rates of O. marina did not differ significantly among nine different K. japonica concentrations. Thus, K. japonica may not affect growth of O. marina. Our findings suggest that the effect of predation by heterotrophic protists on K. japonica might be negligible, and thus, the effect of grazing by K. japonica on populations of red-tide species may not be reduced by mortality due to predation by protists.

Nutrients intake status of 73 lactating women, that is 45 breast feeding (BF), 13 formula feeding (FF) and 15 mixed feeding (MF), living in Daejeon was investigated. Self-recorded food intakes for two weekdays and eating behaviors using questionnaires were surveyed from May to August 2008. Subjects aged $29.2{\pm}3.4$ years and their infants aged $8.2{\pm}3.2$ months. Body mass index of the subjects was $21.0{\pm}3.2$. Of the subjects 23.3% were employed. Daily energy intake was $1953{\pm}391$ kcal. Mean adequacy ratio (MAR) was $0.77{\pm}0.14$ and was higher in FF ($0.86{\pm}0.13$) than in BF ($0.76{\pm}0.11$) and MF ($0.72{\pm}0.18$). Nutrients that over 50% of the subjects took less than estimated average requirement were vitamin A, riboflavin, folate, vitamin C and calcium. And index of nutritional qualities of those 5 nutrients were below one Forty six and sixths percent (46.6%) of the subjects showed GMFVD = 11111 pattern of five food group intakes and 57.5% took meals three times daily, 56.2% skipped often breakfast, and 64.4% dined out two times and more per week. Subjects having lower MAR (< 0.72, n = 24), compared with those having higher MAR (${\geq}$ 0.83, n = 24), showed more skipping daily meals and less frequency of eating-out, and took less legumes, vegetables, fishes, and milk. As the results, intakes of calcium, vitamin A, riboflavin, folate, and vitamin C were insufficient in lactating women, especially in BF and MF mothers. Meal skipping and low intakes of dairy foods, legumes, vegetables, and fishes might have adverse influences on nutritional status of lactating women. Accordingly, nutrition care program for lactating women should be focused on intake of three meals daily and a variety of food.

The objective of this study was to investigate the influence of feeding frequency on a sow's reproductive performance and stress response during gestation. A total of twenty multiparous sows (Yorkshire × Landrace) were used in a completely randomized design based on their parity, body weight (BW), and backfat thickness (BFT), and the sows were allotted to two different feeding systems: 1) once daily feeding (OF) and 2) twice daily feeding (TF) in corn-soybean meal based diets. The gestation diet was formulated to contain 3,265 kcal of metabolizable energy (ME) / kg, 12.90% of crude protein (CP), and 0.75 % of total lysine. The lactation diet was formulated to contain 3,265 kcal of ME / kg, 16.80% of CP, and 1.08% of total lysine and provided ad libitum during lactation. In gestation, sow BFT and BF changes were not affected by feeding frequency, but higher BW and BW gain from day 35 to 90 and day 35 to 110 were observed in OF sow (p < 0.10). In lactation, feeding frequency did not influence on BW, BW gain, BFT, BF changes, average daily feed intake, and wean-to-estrus interval. Also, there were no differences in litter size, litter weight and piglet weight in lactating sows. OF sows had higher (p < 0.05; p < 0.10) protein, solid-not-fat, and total solid concentrations in colostrum compared to TF sows, while OF sows had a lower (p < 0.05) lactose concentration in colostrum compared to TF sows. Sows in OF showed significantly lower average daily water consumption (ADWC) from day 35 to 110 of gestation (p < 0.05). While there were no significant differences in stereotypic behaviors and salivary cortisol levels during gestation between treatments, the OF sows showed less time spending on the activity at day 105 (p < 0.05). In conclusion, reduced feeding frequency increased BW gain during gestation, decreased activation time, and changed the colostrum composition. This information may contribute to the understanding of the physiological and behavioral change of gestating sows by manipulating feeding frequency.

Purpose: The purpose of this study was to identify the factors influencing the reproductive health behavior of married immigrant women (MIW). Methods: A cross-sectional based survey was conducted. The data were collected using a self-reporting questionnaire of MIW who lived in cities and provinces. The data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation, and multiple regression analysis. Results: A total of 141 subjects participated in the study (mean age, $34.23{\pm}6.53$). Of the participants, 45.4% were Vietnamese. The reproductive health behavior score of the subjects was $4.09{\pm}0.51$. The reproductive health behavior showed positive correlations with attitude (r=.37, p<.001), perceived behavioral control (r=.35, p<.001) and intent (r=.33, p<.001). The factors influencing the reproductive health behavior were attitude toward the reproductive health behavior (${\beta}=.24$, p=.005), perceived behavioral control (${\beta}=.18$ p=.046), experience of breast feeding (${\beta}=.20$, p=.014), and the self-evaluated Korean listening ability (${\beta}=.18$, p=.019). These variables explained 29% of the variance in the reproductive health behavior. Conclusion: According to the above results, a specific educational program for MIW is needed to increase their reproductive health behavior.

Nymphal development of the B and Q biotypes of Bemisia tabaci was normal on all seven tomato varieties tested. However, their nymphal development was different on red pepper varieties. B biotype was not normally developed on nine red pepper varieties tested. On the contrary, Q biotype was normally developed, but its adult emergence rate was very low in Nokkwang variety than in other eight varieties. The EPG analysis of the feeding behavior of Bemisia tabaci showed that B and Q biotypes had different duration of phloem phases on red pepper. Q biotype showed longer phloem phases than B biotype. On Nokkwang variety, Q biotype had short phloem phases and did not prefer to feed on Nokkwang variety. Interestingly, Q biotype was found to have long duration of phloem phases on eight red pepper varieties, but B biotype did not prefer to feed on red pepper varieties. However, both biotypes did not show any difference in feeding time on tomato varieties.

Objective : This study introduces domestic and overseas systematic assessment tools that can identify eating problems of dementia patients based on abnormal behavior observations and turns them into Korean through the verification of content placement by expert groups. Methods : Three types of assessment tools were selected for final development in Korean version through several meetings based on a wide range of relevant literature searches. The 3 selected assessment tools were first translated by the researchers, and a 9-person expert team was used to verify the Content Validity Index. Results : The EBS content equivalence calculation shows that all 6 questions and 1 response item had a CVI value 0.9, and all items were included in Korean EBS without modification. The EdFED content equivalence calculation showed that all 11 questions had CVI value 0.9, which was included in the Korean edition of EdFED without modification. The content equivalence calculation of the FDI showed that all 19 questions had a CVI of 0.8 or higher, and all items were included in the Korean version of the FDI without modification of the item. Conclusion : Korean versions of the EBS, EdFED and FDI, which are based on behavioral observation and diet tools for people with dementia, have been developed. Early determination of problems related to diet in dementia patients and providing proper intervention through observational Korean version assessment tools is vital in terms of strengthening patient nutrition and reducing caregivers' burden.
