The purpose of this study is to analyze the mediating effect of career decision-making self-efficacy on the relation between the social support of professors and the career preparation behaviors of students who specialize in foodservice & culinary art. The participants of the study consisted of 250 students from the departments related to foodservice and culinary art of the three universities located in Chungcheong province. A total of 217 responses out of the 250 questionnaire were analyzed without the 33 incomplete questionnaires. The results of this study are as follows. First, it was shown that professors' social support had a significant positive effect on the career decision-making self-efficacy and the career preparation behaviors. Second, it shows that the career decision-making self-efficacy played a partial mediating role when the social support of the professors is related to the career preparation behavior. Therefore, the career education based on emotional, informational, material, and appraisal supports of the professors probably play a critical role in improving the career decision-making self-efficacy and the career preparation behaviors of the students majoring in food service & culinary art.

In recent years, there has been a growing need for measuring consumer demand in overseas markets in order to increase the sales of Korean dried persimmons. The country of origin of products is associated with consumer ethnocentrism and has become one of the important factors for explaining consumer demand in overseas markets. The purpose of this study was to analyze the Taiwanese consumers' preferences and consumption behaviors concerning dried persimmon based on ethnocentrism. Results found no significant differences in the consumer awareness of imported dried persimmons according to the level of ethnocentrism. The perception and preference of Korean dried persimmons were statistically significant in terms of satisfaction, taste, color, safety, packaging, and hardness by level of ethnocentrism. The factors affecting Taiwanese consumer's preference of Korean dried persimmon were found to be the satisfaction of Korean dried persimmon. Age was the most influential factor in the purchase experience of Korean dried persimmon. This implies that it would be necessary to increase consumer awareness of Korean dried persimmons by targeting the segmented market and promoting marketing strategy in the Taiwan market for securing sales channels and generating profit.

This study aims to investigate both general dietary behaviors and clinical symptoms of diet related effects among fifth grade students at an elementary school in Ulsan Metropolitan City, and to categorize those relationships in terms of their comparative differences. The findings of this study are as follows. 1. Out of 694 students polled, 53.7% were of boys and 46.2% were girls with average age of $11.9{\pm}0.3$, average height of $145.1{\pm}6.8cm$, and average weight of $39.7{\pm}9.7kg$. Obesity in boys (5.5%) exceeded girls (3.9%) whereas children categorized as underweight showed girls (14.6%) slightly exceeded boys (10.4%). 2. Dietary behaviors were largely the result of four factors - unbalanced diet, balanced diet, protein and fruits and healthy dietary habits. Of these factors, protein and fruits ($4.04{\pm}1.03$) ranked first, balanced diet ($3.38{\pm}1.04$) second, healthy dietary habits ($3.04{\pm}1.01$) third and unbalanced diet ($2.23{\pm}0.6$) ranked last. 3. When Dietary behaviors were classified with four low ranking factors, they were divided into four types such as convenience (22.4%), good diet (24.7%), busy contemporary modern man (24.3%) and healthy dietary habits (26%). 4. Clinical symptoms include colds ($2.27{\pm}1.15$) followed by headaches ($2.17{\pm}1.19$), stomachaches ($2.16{\pm}1.15$), dizziness ($2.02{\pm}1.15$), atopic allergy ($1.95{\pm}1.30$), prevalence for cold sores ($1.86{\pm}1.07$), allergy ($1.65{\pm}1.05$), and constipation ($1.54{\pm}0.87$). 5. According to the results, clinical symptoms were divided into two groups - unhealthy (40.1%) and healthy (59.9%). 6. By analyzing the relationship between dietary behavior types and clinical symptom types, the convenience factor included slightly more of the unhealthy group (56.3%), whereas the good diet (71.1%), busy contemporary modern person (55.8%) and healthy dietary habits (69.7%) included more of healthy group (p<.001). Since the majority of students belonging to the unhealthy group had convenience dietary behavior, education about desirable dietary activities is needed for these students. In addition, nutrition information and information on possible clinical symptoms caused by nutritional imbalance should be provided for students and their households.

A large number of chemical pollutants including phthalates, alkylphenolic compounds and organochlorine pesticides have the ability to disrupt endocrine function in animals, and alter cog-nitive function. Because hormone mediated events play an important role in central nervous system development and function, the changes in cognitive function seem to be mediated by the endocrine-like action of these chemicals. The present study therefore was designed to investigate effect of bisphenol A (BPA), an endocrine disrupting chemical on neuro-behavial patterns, and expression of estrogen receptors and tyrosine hydroxylase, a limiting enzyme of dopamine synthesis pathway. BPA was treated orally for 3 weeks into 3 week old mice, and then the neuro-behavial patterns (stereo-type behaviors such as jumping rearing and forepaw tremor, climbing behavior, tail flick, rotarod and locomotor activity), and the expression of estrogen receptors and tyrosine hydroxylase were deter-mined every 3 week for 9 weeks. During the treatment of BPA, the food uptake and body weight increase were not significantly changed. BPA resulted in the increased stereotype behaviors (jump-ing, rearing and forepaw tremor) 6 or 9 weeks after treatment. The time response to tail flick and locomotor activity were decreased by the treatment of BPA, whereas the time for rotarod was increased by the treatment of BPA. The expression of estrogen receptor alpha and beta was increased in the brain and pituitary gland. Maximum expression was found in the brain after 9 week of 100 mg/kg BPA treatment and in the pituitary gland after 6 week of 100 mg/kg BPA treatment. Tyrosine hydroxylase was increased in dose and time dependent manners in the brain but no change was found in the pituitary gland. The present data show that exposure of BPA in the young mice could alter expression of estrogen receptors and dopamine synthesis pathway, thereby modulate neuro-behavial patterns (increase of stereotype behaviors but decrease locomotor activity).

The purpose of this study was to investigate consumer's behaviors on the laundering of baby's clothing according to washing machine types. The subjects were 255 consumers with babies(0-2 years) in Korea. The data were collected with a self-administered questionnaire and analyzed by Chi-square test and multiple response analysis, and SPSS 12.0 statistics package was used. Consumers were separated into two groups according to washing machine types with general pulsator type and drum-type. Consumer's behaviors between general pulsator type group and drum-type group of washing machines were also examined. The results of this study were as follows. In the consumer satisfaction for washing machine, mostly drum-type group of consumers were satisfied with their washing machines. As the reasons of washing machine's dissatisfaction, noise, washing time and low washing efficiency were high in the pulsator type group, and washing time, noise and high price in the drum-type washing machine group. The consumers concerned about separation of clothing and laundering label while they washed laundry by washing machine. However, they didn't separate clothing because the small volume of laundry and a long washing time. The most interest and required thing of consumers was complete rinsing without any detergents used in washing as well as the removal of soils for baby's clothing regardless of two washing machine types. And they complained food soils like milk and mother's milk etc. were not completely removed by washing machine. As a whole the washing frequency of baby's laundry was once per a day and the rinsing also more than three times per a laundry. Most of the consumers used a private detergents for baby's clothing(detergents for baby's clothing only), and preferred to the high or boiled temperature washing as a desirable baby's laundering. There were significant differences between general pulsator type group and drum-type group of washing machines on the laundering of baby's clothing in this study.

This study evaluated the dietary habits and health behaviors of Korean adolescents according to their nutrition label utilization. This study was conducted on the adolescents aged between 12 and 18 who participated in the 2016-2018 National Health and Nutrition Examination Survey. Subjects were classified into nutrition label utilizing group and non-utilizing group. Then the general information, diet habit and nutrient intakes, health status and obesity and mental health of the two groups were analyzed. There was no significant difference in skipping breakfast, frequency of eating out, smoking status and alcohol drinking status according to the utilization of nutrition labels. Nutrition label utilizing group had higher % KDRI of protein(p<0.05), calcium (p<0.01), phosphorus(p<0.01) and potassium intakes(p<0.01) than non-utilizing group. Nutrition label utilizing group had higher EQ-5D score(0.97) than non-utilizing group(p<0.001). Practical nutrition education using nutrition label is needed. So these results can be useful for supporting dietary education regarding use of nutrition label for adolescents.

A total of 24 specimens of the pufferfish, Fugu xanthopterus, purchased at a fixhmarket in Pusan, korea were examined for toxicity using the assay method of tetrodotoxin (TTX). Also, the toxins isolated from the puffer liver were partially purified and analyzed for their chemical composition by instrumental behaviors. On the whole, when the level of toxicity in each organ was analyzed compared to that of liver, they were 100 % of the lover, 92 % for the intestine, 75% for the skin, 17% for the muscle, 785 for the testis, 87% for the ovary, and 71% for bile. The highest and average scores of toxicity for the liver were 917 and $231{\pm}51MU/g$ liver, respectively. The toxins of the puffer gave four peaks in HPLC whose retention times (10, 20, 22 and 25 min) were close to those of TDA, TTX, 4-epi-TTX, and and -TTX, respectively.
