In order to study factors affecting the use of the ambulatory physician services. Andersen's model for health utilization was modified by adding the health behavior component and examined with three different approaches. Three different approaches were the multiople regression model, logistic regression model, and LISREL model. For multiple regression, dependent variable was reported illness-related visits to a physician during past one year and independent variables are variaous variables measuring predisposing factor, enabling factor, need factor and health behavior. For the logistic regression, dependent variable was visit or no-visit to a physician during past one year and independent variables were same as the multiple regression analysis. For the LISREL, five endogenous variables of health utiliztion, predisposing factor, enabling factor, need factor, and health behavior and 20 exogeneous variables which measures five endogenous variables were used. According to the multiple regression analysis, chronic illness, health status, perceived health status of the need factor; residence, sex, age, marital status, education of the predisposing factor ; health insurance, usual source for medical care of enabling factor were the siginificant exploratory variables for the health utilization. Out of the logistic regression analysis, health status, chronic illness, residence, marital status, education, drinking, use of health aid were found to be significant exploratory variables. From LISREL, need factor affect utilization most following by predisposing factor, enabling factor and health behavior. For LISREL model, age, education, and residence for predisposing factor; health status, chronic illess, and perceived health status for need factor; medical insurance for enabling factor; and doing any kind of health behavior for the health behavior were found as the significant observed variables for each theoretical variables.

Purpose - This purpose of this research is to verify the influence of the care workers' environment on their job satisfaction and on their voluntary behavior. Research design, data, and methodology - Data were collected from care workers at elderly medical and home care facilities in Korea in Seoul and Kyung-ki. Of 367 total respondents, 285 responses were used. This study performed exploratory factor analysis in order to verify the validity and credibility of the data. Regression analysis was conducted to verify the influence of the working environment, which encompasses the worker's relationship with the agency and with the elderly, on job satisfaction. Results - The hypothesis results were: First, from analyzing the influence of the working environment on the worker's job satisfaction, both relationship with the agency (p<.001) and relationship with the elderly (p<.05) positively affect job satisfaction; second, the exploratory analysis verifies the influence or the working environment on job satisfaction. Conclusions - The results indicate that the relationship with the agency (p<.001) and relationship with the elderly (p<.001) both positively affect the voluntary behavior of the workers.

The attachment of Korean infants with their mothers was analyzed by individual attachment and interaction behaviors. The Strange Situation was used with 35 12- 18-month-old infants. Results were similar to the findings of Ainsworth et al(l978), in that exploratory and attachment behavior systems of Korean infants changed depending on separation with their mothers. Then again we could discover the orginal attachment characteristics of Korean infants. Korean infants showed meaningful differences in individual attachment and interaction behaviors from the second separation(episode 6), and the difference between attachnet type were also definite from the second separation. Also, the recovery of exploratory behavior from episode 7 with the advent of a stranger was a distinguishable characteristic compared to Ainsworth et al(l978). This empirical evidence mandates the inclusion of episodes 6 in future studies on attachment of Korean infants.

Objectives: This study was conducted to develop and validate Eating Behaviors Test form (EBT) for infants and young children, including eating behaviors of their parents and parental feeding practices. Methods: Draft version of EBT form was developed after a pretest on 83 mothers. It was consisted of 42 questions including 3 components; eating behavior of children, eating behavior of parents, and parental feeding practices. Using these questionnaires, the first survey was conducted on 320 infants and children, 1 to 6 year old, for exploratory factor analysis, and the second survey was collected on 731 infants and children for confirmatory factor analysis. Results: Exploratory factor analysis on 42 questions of EBT form resulted in 3 factor model for children's eating behavior, 3 factor model for parents' eating behavior, and 1 factor model for parental feeding practices. Three factors for children's eating behavior could be explained as follows; factor 1, pickiness (reliability ${\alpha}=0.89$; explanation of variance=27.79), factor 2, over activity (${\alpha}=0.80$, explanation of variance=16.51), and factor 3, irregularity (${\alpha}=0.59$, explanation of variance=10.01). Three factors for mother's eating behavior could be explained as follows; factor 1,irregularities (${\alpha}=0.73$, explanation of variance=21.73), factor 2, pickiness (${\alpha}=0.65$, explanation of variance= 20.16), and factor 3, permissiveness (${\alpha}=0.60$, explanation of variance=19.13). Confirmatory factor analysis confirmed an acceptance fit for these models. Internal consistencies for these factors were above 0.6. Conclusions: Our results indicated that EBT form is a valid tool to measure comprehensive eating and feeding behaviors for infants and young children.

Results of an experiment on the behavior of rats and mice in order to explore the possible pharmacological actions of Panax ginseng upon the central nervous system can be summarized as follows: 1. Spontaneous motor activity. In the case of mice, those groups who were administered 2.5 mg and 5.0mg of ginseng saponin per kilogram of body weight were observed to have increased their activity compared with the control group, while the 50.0 mg and 100.0 mg per kilogram body weight groups demonstrated lower levels of activity, with the peak of activity appearing at 30 minutes after administration of drugs. In the case of rats, those groups of animals who were given injections in the dosage of 2.5 mg, 5.0 mg and 50.0 mg per kilogram body weight demonstrated higher activity than the control group, while the 100.0 mg per kilogram group appeared to have decreased in their activity, with the peak action appearing 30 minutes after the administration of ginseng saponin. The 50.0 mg per kilogram group demonstrated no significant differential. 2. General behavior analysis. In the case of mice, decrease in sleeping component of behavior and increase in the walking and roaring components, compared those with the control group, turned out to be a common phenomenon among the groups who were administered 2.5 mg, 5.0 mg and 50.0 mg of ginseng saponin per kilogram body weight, with the 5.0 mg per kilogram group standing out of all the other groups in terms of their reactions. In the case of rats, ginseng saponin appeared to reduce sleeping component with 2.5 mg, 5.0 mg and 50.0 mg per kilogram body weight groups, while increased the walking and rearing components. It was observed that administratoin of ginseng saponin in a dose of 2.5 mg per kilogram appeared to markedly increase the lying and grooming components of animal behavior. 3. Open-field exploratory behavior. Adminstration of ginseng saponin to mice in doses of 5.0 mg, 50.0 mg and 100.0 mg per kilogram body weight decreased activity, but increased their exploratory behavior. In the case of rats, however, administration of ginseng saponin in the doses of 2.5 mg and 5.0 mg per kilogram body weight markedly increased their activities, while decreased activities with the 50.0 mg per kilogram and 100.0 mg per kilogram groups. The exploratory behavior of rats appeared to have decreased, while grooming increased ramarkably. 4. The above findings from a series of experiment appear to suggest a stimulating effect on the central nervous system when ginseng saponin is administered in small doses, but that larger doses might result in an inhibitory effect, though differential results can be anticipated with modification of experimental conditions.

To investigate the effects of neonatal stress on behavior and neurochemistry, rats were exposed to the footshock stress on postnatal day (PND) 14 or PNDs 14 and 21. Rats were exposed to uncontrollable electric shocks delivered to the floor with a constant current (0.8 mA) for 5 sec period. Daily sessions consisted of 60 trials on a random time schedule with an average of 55 sec. The first exposure to footshocks on PND 14 decreased body weight gain for 1 day. However, the second exposure to footshocks on PND 21 did not affect body weight gain. Exploratory activity was measured by exposing a rat to a novel environment 24 h after experience of footshocks. Similar to the body weight changes, a decreased activity was noted after the first exposure to footshocks, while no changed activity was noted after the second exposure to footshocks. However, the Bmax value of $5-HT_{2A/2C}$ receptors in the cortex decreased by the second exposure to footshocks, but not by the first exposure to footshocks. Moreover, an autoradiographic study revealed that the density of $[^3H]dexamethasone$ binding in hippocampus decreased in rats exposed to footshocks 4 times during PND $14{\sim}20.$ These results suggest that the uncontrollable footshock stress changes 5-hydroxytryptamine and glucocorticoid receptor systems acutely and that the repeated exposure to the same stress may not elicit behavioral alterations by the compensatory activity of young brain although changes in some neurochemistry exist.

BACKGROUND/OBJECTIVES: The increased consumers' interests in health and food safety have increased the demand for organic foods. Many studies have been performed on consumers' purchase intentions for organic foods and their influencing factors, and various studies have shown that the prices of organic foods and the consumers' willingness to pay are important influencing factors. This study examined the payment value of organic foods and agrifood consumer competency index according to the food-related lifestyles in South Korean consumers. SUBJECTS/METHODS: A cross-sectional analysis was performed using the 2019 Consumer Behavior Survey for Food. A total of 6,176 participants aged 19 to 74 years (male: 2,783, female: 3,393) were included in the analysis. RESULTS: Three factors were extracted by factor analysis (rational consumption-seeking type, convenience-seeking type, and health, and safety-seeking type) to explain the consumers' food-related lifestyles. The results of cluster analysis suggested that consumers were classified into 3 food-related lifestyles as the 'exploratory consumers' (n = 2,485), 'safety-seeking consumers' (n = 1,544), and 'passive consumers' (n = 2,147). Exploratory consumers showed a significantly higher willingness to pay for imported organic foods (P < 0.05). Safety-seeking consumers had a significantly higher willingness to pay for domestic organic foods (P < 0.05). For the agrifood consumer competency index, exploratory consumers had the highest score, followed in order by safety-seeking consumers and passive consumers. CONCLUSIONS: These results provide basic data in understanding consumption tendency for organic foods and agrifoods based on food-related lifestyles of South Korean consumers.

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.
