The changes of feeding pattern and the amount of insecticide penetrated into the leaf were monitored for 420 min after treatment of three concentrations of dinotefuran. At about 30 min after treatment of insecticide, the overall feeding pattern in EPG (Electrical Penetration Graph) monitoring was started to change, and there was significant difference in proportions of NP (non-penetration), PA (pathway activity), and phloem-feeding patterns among the different concentrations of dinotefuran treatment. Especially, as the amount of insecticide penetrated into a leaf increased, the reactive behaviors against this insecticide such as withdrawal of proboscis and movements of stylet of aphid were more quickly exhibited. And also, total time at which the proboscis of the aphids did not penetrate the plant was getting longer. The amount of dinotefuran penetrated into a leaf was monitored with HPLC. When the recommended concentration (100 ㎎/L) of the insecticide was treated, 5.24~7.24 ㎎/L of the insecticide was detected from the leaf, and the proboscis of the aphids was apparently withdrawn from the leaf at approximately 60 minutes after treatment of this insecticide.

The purpose of this study was to investigate the consumer characteristics in foodservice according to university students' lifestyles. The data were collected by the questionnaire survey of 520 university students from Daegu Gyeongbuk Province. The SPSS/Win 12.0 program was used to analyse the samples. The results are as follows: 1) Lifestyle was divided into 10 factors and 3 clusters, namely "Convenience Intention" (cluster I), "Health Information Intention" (cluster II), and "Gender Equality Intention" (cluster III). 2) The differences in general characteristics between the three clusters were founded on gender, frequency of visits, companion, information type, and the type of restaurant. 3) The characteristics of cluster I (Convenience Intention) are explained by it consisting of the group with low averages in consumer dissatisfaction, complaints, compensation, and repurchase intention, where as cluster II was the high average group and cluster III the middle average group. Based on these results, consumer characteristics in foodservice are discussed.

This study was conducted to investigate the vegetable eating behaviors and preferences of elementary school students by stage of change for vegetable intake. The subjects consisted of 191 fourth and fifth grade elementary school students from Gyeonggi province. The stage of change for vegetable intake was categorized into three groups: precontemplation (PC, 18.4%), preparation (P, 43.5%), and action/maintenance (A&M, 48.2%). The trend to eat a variety of foods was more distinctive as the students went from the PC to the A&M stage. The stage of change for vegetable intake was closely related with the kimchi-eating pattern of the students. The A&M group ate more vegetables than the PC group because they liked vegetables and/or wanted to prevent disease. The PC group had a lower tendency to follow recommendations for vegetable eating than the P and A&M groups. The PC group also had an incorrect notion that low vegetable consumption over an extended time would not have a big impact on their health. The vegetables of high preference for the elementary school students were potato, sweet potato, lettuce, radish, perilla leaf, cucumber, and cabbage. The vegetables of low preference were spinach, onion, balloon flower, and green pepper. The PC group had lower preferences for most vegetables than the P and A&M groups. Therefore, careful nutrition education is necessary especially for students in the PC group in order to explain the positive effects of vegetable intake and negative effects of an unbalanced diet. It is also necessary to survey students' tastes consistently and to develop recipes that encourage them to consume more vegetables agreeably.

The purpose of this study verifies: the relationships between trust in supervisor and innovative behavior, and mediator effect of the organizational commitment(affective commitment, continuance commitment). In order to verify the relationships and mediator effect, data obtained from 140 employees working in business office in Ulsan Metropolitan City and they were analyzed by using SPSS 12.0. The findings are as follows: First, the relationship between trust in supervisor and the organizational commitment(affective commitment, continuance commitment) is positively related. Second, there was also a positive correlation between affective commitment and innovative behavior. Finally, affective commitment played as a partial mediator on the relationship between trust in supervisor and innovative behavior. However, there was no empirical evidence for the mediating effect of continuance commitment on the relationship between trust in supervisor and innovative behavior. Based on these findings, the implications and the limitations of the study were presented including some directions for future studies.

Consumers are very concerned about food safety as the risk with food increased. This study was conducted to evaluate the perceptions and practices of consumers on food safety in order to collect some information for the development of consumer education program. Total 500 consumers were asked to answer for survey constituted with 6 questions of generic information, 4 of food safety perceptions and 8 of food safety practices from June to July, 2006. More than half of respondents (51.8%) were unsatisfied with the food safety management of government while the individual practices on food safety were satisfactory. Especially, most respondents (98.7%) checked the expiration date of food when they purchased and 97% of respondents were washed hands before food preparation. The higher food safety perception, the better food safety practices of consumers. These results suggest that the systematic and continuous educations on food safety hazards and the principles of sanitation management are necessary for safe food handling and perception on food safety.

Prostaglandin () can facilitate release of epinephrine from the adrenal gland. The objective was to extend these findings and determine the effects of on sexual activity and semen collection training in sexually inexperienced boars. Boars (n=32; days of age) were moved individually once weekly to a semen collection room equipped with an artificial sow. Before entering the semen collection room, boar received i.m. treatments of at doses of 5 (n=8), 10 (n=8), or 20 (n=8), and control boar (n=8) were not treated. Reaction time (elapsed time after entering collection pen until the start of mounting) for boars receiving 5mg (), 10mg () was shorter (p<0.05) than for controls (). Duration of ejaculation (min) per session was longer (p<0.05) for (10 mg, 20 mg)-treated boars (, ), compared to control (). The number of training session per boars was less (p=0.056) for 10mg-treated boars (), compared to control (). Semen characteristic such as volume, concentration, the number of total ejaculated sperm, were similar for -treated and controls. There was no apparent difference on sperm movement characteristics (Mot: motility, VCL : curve linear velocity, VSL : straight line velocity, VAP : average path velocity, LIN : linearity) after semen preservation by collected with or without treatment. In summary, administration of in boars increased the sexual activity and facilitated the training boars to mount an artificial sow for semen collection, but did not affect semen characteristic.

목적 : 자폐아동의 상동행동 감소를 위한 중재방법으로 조건부 운동방법을 통한 응용행동분석과 감각통합치료의 효과를 비교하고자 한다.연구방법 : 본 연구는 개별실험 연구 설계인 교차중재설계(alternating treatment design)방법을 사용하여 응용행동분석의 조건부 운동방법과 감각통합치료를 상호 교차해서 상동행동을 치료 하였다. 연구대상은 중증 정신지체와 자폐증상을 갖고 정신지체아동 시설에서 생활하는 만 8세 10개월 된 남아였다. 상동행동 감소를 위한 중재방법으로 1회기에 20분씩 감각통합 치료와 조건부 운동 방법을 교차하면서 각 5회씩 실시하였다. 상동행동은 시각적 상동행동과 손가락 상동행동으로 나누어 측정하였다. 종속변인의 측정은 페그를 끼우는 과제수행 과정 중에 발생하는 상동행동을 비디오로 촬영한 후, 등간 기록법(interval recording)으로 기초선 2회, 교차중재과정 10회, 일반화과정 1회 실시하였다.결과 : 치료 전에는 시각적 상동행동이 10분에 평균 21회(4～40회) 발생했으나 중재 후에는 감각통합 치료 후에 평균 1회(0～3회), 조건부 운동 후에는 평균 1.6회(0～10회)로 감소했고, 손가락 상동행동은 치료 전에는 평균 28회(10～36회), 감각통합치료 후에는 평균 3.5회(0～12회), 조건부 운동 후에는 평균 5.7회(0～16회)로 감소하였다. 치료 종료 3주 후에 상동행동을 10분간 페그를 끼우는 상태에서 1회 측정했을 때, 시각적 상동행동이 4～10회, 손가락 상동행동이 4～6회 발생한 것으로 보아 상동행동 치료효과가 적절히 유지된 것으로 보인다.결론 : 상동행동 감소를 위해 사용된 감각통합치료와 조건부 운동 방법을 통한 응용행동분석 모두 효과가 높은 것으로 나타났지만, 이 두 방법의 치료효과 비교에서는 현저한 가시적 차이를 보이지는 않았다.
