Well-designed housing systems are important from the viewpoint of animal welfare and improvement of meat production. In this study, we investigated the effects of outdoor housing of pigs on their behavior, cortisol levels, and meat characteristics. Two groups that were born and raised in a spacious outdoor pen ($4{\times}10$ m for every two sows) or a minimum-sized standard pen in a piggery ($1.9{\times}2.2$ m for every sow) were studied. When their behaviors at the age of 2 to 3 wk were observed, the number of rooting episodes tended to be larger (p = 0.0509) and the total time of rooting tended to be longer (p = 0.0640) in the outdoor-housed piglets although the difference was not significant. Basal salivary cortisol levels of the outdoor piglets at the age of 4 wk were significantly lower than those of the indoor piglets ($5.0{\pm}0.59$ ng/ml vs. $11.6{\pm}0.91$ ng/ml, 30 min after treatment), although their plasma cortisol levels were similar ($53.3{\pm}3.54$ ng/ml vs. $59.9{\pm}4.84$ ng/ml, 30 min after treatment). When the ears were pierced at weaning, plasma and salivary cortisol levels were increased in both groups, even at 15 min after piercing. However, the increase in the outdoor-housed group was significantly less than that in the indoor-housed group. Throughout their lives, body weight and daily gain of the pigs were not significantly different between the two groups. In a meat taste preference test taken by 20 panelists, saltiness, flavor, and color of the outdoor-housed pork were found to be more acceptable. Moreover, when an electronic taste-sensing device was utilized, the C00 and CPA-C00 outputs ($3.78{\pm}0.07$ and $-0.20{\pm}0.023$), which correspond to compounds of bitterness and smells, respectively, were significantly lower in the outdoor-housed pork ($5.03{\pm}0.16$ and $-0.13{\pm}0.009$). Our results demonstrate that the outdoor housing system for piglets induces natural behaviors such as rooting and suppresses the strongest stress reaction of piglets, which could be important for animal welfare. Moreover, the outdoor housing system might change muscle characteristics and improve pork bitterness, flavor, and color. These changes may be preferred by consumers, increasing the sale of these meats.

Mother and infant relationship has a great influence on child's developments. In this study, nursing intervention to increase maternal sensitivity to the infant's cues was applied to 25 primiparas (Experimental Group). Mother and infant interacations of these primiparas were compared with those of 25 primiparas (Control Group) who did not receive the nursing intervention. Fifty primiparas and infants were recruited from a university hospital, a general hospital, and an OBGY clinic located in Taegu city. Mother and infant interactions were assessed at 6 weeks after birth using videotapes. Feeding situations were videotaped and two trained observers analyzed the tapes. Data were collected from March 23rd to July 27th of 1998. Mother and infant interactions during feeding were assessed by the response rating scale which was modified by the author based on NCAST feeding scale (Barnard, 1978a) and AMIS scale (Price, 1983). The validity of the modified rating scale was verified by faculty members and researchers who previously had research experience in the area. Cronbach's Alpha of the modified scale for this study was .90. The data was analyzed by SAS program, using wilcoxon rank sums test, chi square test, Fisher's exact test, and ANOVA. Findings were as follows: 1. Mothers in the experimental group were more likely to have higher scores in mother and infant interactions during feeding than mothers in the control group. 2. Mothers in the experimental group showed better sensitivity to infant's signals or cues, provided growth fostering, and had higher responsibility to the infant's distress than mothers in the control group. 3. Infants in the experimental group showed higher clarity of cues and responsibility to the mother's behaviors than infants in the control group. 4. Mothers and infants in the experimental group showed higher synchronic responses than mothers and infants in the control group. In conclusion, this study has shown that the applied nursing intervention promoted mother and infant interaction among primiparas. Therefore, this study suggests that the nursing interventions to increase maternal sensitivity to the infant's cues should be broadly applied to primiparas, which can be beneficial to the social, affective, and cognitive developments of their children.

This retrospective study was conducted to investigate the growth of children and their care person's weaning behaviors and its relation between the growth and care person's attitude and behaviors about weaning. 272 subjects who had child under 2 years old at that time were randomly selected and answered the special questionnaire. Results were as follows: Using to Kaup index, 13.4% of children were estimated undernutrition, 60.6% were normal and 26.0% were estimated overnutrition. 97.6% of respondant (children's mother) were recognized the need of weaning and the first prurpose of weaning was supplement of nutrients, and the next one was to set up normal food habits. 39.1% of subjects were used normal adult foods as weaning food. 60.9% of subjects were proepared special foods (making at home or buying commercial weaning food). The socioeconomic status was major factor to influence mother's behaviors about weaning. Vegetable and meat gruel was the most commen weaning food and the next one was fruits puree and rice with soup. The correlationship were found between Kaup index and the score of mother's weaning behaviors, between momer's eductional level and the score of weanig behaviors. 96% of subjects wanted nutritional education about weaning. They wanted to know about desirable weaning process and correct informations of commercial weaning foods mid the convenient cooking methods. According to the difference of socioeconomic status subjects were wanted different eductional methods. Upper socioeconomic group wanted special books about weaning and lower class wanted to be educted through the mass media especially television programs.

This study prospective randomized controlled trial aims to test the impact of adding health education, awareness of some contributing factors and clinical guidance to therapeutic cabergoline given to infertile women with unexplained resistant hyperprolactinemia. It comprised 120 infertile women with unexplained persistent hyperprolactinemia not responding to therapeutic doses of cabergoline 1.5-2 mg/week who were subjected to proper history taking to exclude concomitant drug intake or possible brain problems in all cases. They were classified into group A (60 cases) who received health education and clinical guidance to search for possible contributing factors and were instructed to avoid them in addition to proper therapeutic doses of cabergoline, while group B (60 cases) received proper therapeutic doses of cabergoline only without clinical guidance. After 1 month, serum prolactin (PRL) was measured for all cases. All cases had high PRL level at the start of the study (79.9±28.4 [39-195] and 78.2±19.9 [42-189] in group A and B, respectively) without any significant difference. Pretreatment counselling revealed that lifestyle factors, sexual behaviors or feeding habits may contribute to resistant hyperprolactinemia in all cases without a significant difference between both groups. Serum PRL dropped significantly more in group A (20.14±10.31 [11-45] vs. 49.32±37.03 [12-100]) after combined health education, clinical guidance of the couple and proper treatment. It is concluded that lifestyle factors, sexual behaviors, and feeding habits would affect the response of hyperprolactinemia to treatment. Health education and clinical guidance with some advice to avoid them, would concomitantly improve the response of resistant hyperprolactinemia to therapeutic doses of dopamine agonists.

Feeding behaviors of the pear psylla, Cacopsylla pyricola, and their changing feeding behaviors were recorded and analyzed with an electrical penetration graph (EPG) analysis against 5 insecticides. And their mortality against insecticides were carried out in the laboratory. General feeding behavior patterns of C. pyricola were changed by insecticide treatments. Especially, the type and frequency of waveforms differently occurred depending on a sort of insecticides treated. Total duration of transition to waveform PE1 and phloem ingestion (waveform PE2) were significantly different between treatment and non-treatment of insecticides. When 5 different insecticides were treated on pear leaves, difference of feeding patterns were recorded. In case of treatment of benfuracarb, total duration of non-probes (waveform Np) was appeared higher than any other insecticide. However, when flonicamid and deltamethrin were treatment, total duration of stylet penetration (waveform PA) and xylem ingestion (waveform PG) were appeared higher than other insecticide, respectively. As results feeding behaviour of C. pyricola after treated insecticides with time-based consumed rate of C. pyricola, the rate of non-probe (waveform Np) was longer than start penetration (waveform PA), penetration and ingestion in parenchyma cells (waveform PC1+PC2), ingestion at phloem (waveform PD+PE1+PE2) and xylem (waveform PG). As result of direct spray treatment to C. pyricola, mortality of C. pyricola against imidacloprid was higher than any other insecticide on 24 hours after treatment. However, all of insecticides showed 100% mortality of after 48 hours. On the other hand, when 5 insecticides sprayed on the pear leaves and then C. pyricola located on the treated leaves, benfuracarb showed the most toxicity against C. pyricola among insecticides. These result was consistent with the EPG results that showed relatively longer total duration time of waveform Np (non-probes) by benfuracarb treatment.

In order to examine allergic disease experience rates of students at atopy and asthma friendly elementary schools located in Chungcheongnam-do and investigate their dietary behaviors, a survey on 250 parents of first to third grade students at four rural-type atopy and asthma friendly elementary schools was conducted. The number of students who had experienced allergic symptoms (allergic group) was 102 (40.8%). their breastfeeding duration was shorter than that of the non-allergic group (p<.001) and the former's weaning foods-feeding had started earlier than the latter's (p<.01). Regarding the eating habits, the non-allergic group was found to have breakfast and dinner better than the allergic group (p<.001). The number of students eating fruits as snacks was largest in the allergic group at 73 (71.6%), and as for the non-allergic group, their rate of eating fruits, milk and dairy products, and cookies and fries was at 25.7%, 22.3%, and 20.3%, respectively. A high percentage of the allergic group ate three times or less per month the animal food groups and dairy products (p<.001). Accordingly, for improvement in dietary behaviors of students who have allergy against food, nutrition education on regular eating, balanced intake of food, adequate intake of snacks and meals for proper growth and development and precise diagnosis of allergy-triggering food are necessary. In particular, as education on food allergy, implementation of practical education such as appropriate nutrition counseling by nutrition teachers is urgent beyond the one-way educational method of school newsletters.

Objectives: Screen time refers to the time spent using screen media, such as televisions, smartphones, computers, or tablets. Excessive exposure to screen media has been reported to negatively impact young children's health and development, including overweight, short sleep duration, and language delays. This study examined the association of screen time and mealtime media use with dietary behaviors among preschool children. Methods: A cross-sectional survey was conducted on parents of children aged three to five years using the online questionnaires of the Nutrition Quotient for Preschoolers (NQ-P) and the Dietary Screening Test (DST). Data from 261 children's parents were analyzed. Results: Of the 261 children, 96.9% used screen media, 55.6% used screen media for two hours or more daily, and 30.7% were exposed to screen media during meals. The NQ-P scores were significantly lower in the children with longer screen time and mealtime media use. Children who used screen media for two hours or more and those exposed to screen media during meals consumed kimchi less frequently and confectionery and sugar-sweetened beverages more frequently than children who used less than two hours and were not exposed to screen media during meals. In addition, they were more likely to be picky about food, refuse to eat, and less likely to feed themselves than children with shorter screen time and no mealtime media use. Conclusions: This study reported an association between unhealthy dietary behaviors, feeding difficulties, and screen time and mealtime media use among preschool children. Further research should explore effective strategies for reducing children's screen time.

The purpose of this study was to examine the long term effects of breast feeding on growth, bone development and nutrient intakes in preschool children. Subjects were 62 preschool children. Anthropometric characteristics and bone mineral density of carpus were measured using DEXA. The questionnaire was composed of health status, life style, dietary behaviors, and dietary intakes and was completed by the children's mothers. The average age of the boys was 62.4 months and that of the girls was 62.1 months. Average birth height and weight of the subjects was 50.9 cm and 3.4 kg for boys and 50.3 cm and 3.3 kg for girls, respectively. The average height, weight, $\%$ body fat, and obesity index were 111.7 cm, 19.6 kg, $15.0\%$, $-2.1\%$ in boys and 109.4 em, 18.7 kg, $17.5\%$, $0.2\%$ in girls, respectively. Forty children were fed colostrum, 21 were fed breast milk, 29 were fed formula, and 12 were fed mixed milk. There was no significant difference in growth status between children who were fed colostrum and those who were not. Children who had mixed feedings were significantly taller than those who did not (p <0.001), and children who had colostrum had significantly higher bone mineral density than those who did not ($0.25 \pm 0.04 g/ cm^2$ vs. $0.23 \pm 0.04 g/cm^2$, p < 0.05). However, the different feeding methods did not show any difference in bone mineral density. Except vitamin $B_6$, folic acid and vitamin E, vitamin, mineral and calorie intakes did not meet the Korean RDAs. Calcium intake was especially lower than recommendations by as much as $62\%$ and $70\%$ in boys and girls, respectively. There was no significant difference in nutrient intakes between children who had colostrum and those who did not. However, children who were formula consumed significantly more animal fat than those who did not (p < 0.05). Neonatal feeding and breast or formula feeding seems to associate with height, bone mineral density and animal fat intakes in preschool children, based on the results of this study. A longitudinal study is needed to clarify this relationship.

Food is important to any animal, and a large part of the behavioral repertoire is concerned with ensuring adequate nutrition. Two main nutritional sensations, hunger and satiety, produce opposite behaviors. Hungry animals seek food, increase exploratory behavior and continue feeding once they encounter food. Satiated animals decrease exploratory behavior, take rest, and stop feeding. The signals of hunger or satiety and their effects on physiology and behavior will depend not only on the animal's current nutritional status, but also on its experience and the environment in which the animal evolved. In our novel, nutritionally rich environment, improper control of appetite contributes to diseases from anorexia to the current epidemic of obesity. Despite extraordinary recent advances, genetic contribution to appetite control is still poorly understood partly due to lack of simple genetic model systems. In this review, we will discuss current understanding of molecular and cellular mechanisms by which animals regulate food intake depending on their nutritional status. Then, focusing on relatively less known muscarinic and cGMP signals, we will discuss how the molecular and behavioral aspects of hunger and satiety are conserved in a simple invertebrate model system, Caenorhabditis elegans so as for us to use it to understand the genetics of appetite control.

Purpose: This study was conducted to analyze and clarify the concept of the effective breastfeeding. Methods: This study used Walker and Avant's process of concept analysis. Results: Effective breastfeeding is how to give infant adequate milk, which fulfills needs of mother and infant, from her breast so that they can be satisfied with the process and results. It included the effective breastfeeding properties as follows: feeding behaviors (positioning, latch on, and suckling), transferring a breast milk to an infant, mother-infant interaction, and satisfying their desires (satisfaction, comfort, mother's self-confidence, infant's adequate weight gain and defecation, adequate breastfeeding interval). The antecedent of effective breastfeeding were anatomical and functional normal breast, breastfeeding knowledge and steady-state of mother, and feeding desire, rooting reflex and normal oral cavity of infant. The consequences of effective breastfeeding were exclusive breastfeeding, infant and maternal health and wellbeing, and achievement of mother and infant attachment. Conclusion: The meaning of effective breastfeeding defined in this study will contribute to develop the effectiveness breastfeeding assessment tool and the nursing intervention for ineffective breastfeeding.
