The aim of this study was to identify the interrelationship among the motives for selecting a teaching profession, job satisfaction, and the burnout of preschool teachers. In particular, this study examined the mediating effect of job satisfaction on the relationship between their motives and burnout. Data were collected from a group of 200 kindergarten and daycare center teachers working in Seoul, Choongnam and Kyeonggi Provinces. Data analysis was conducted using the PASW Statistics 18.0. The results are as follows. First, there were correlations among their motives for occupational choice, job satisfaction, and burnout. Their motives for selecting a teaching profession and job satisfaction had an influence on their burnout. Second, job satisfaction had a mediating effect on the relationship between motives for selecting a teaching profession and burnout of preschool teachers. These results suggest that improvements of their job satisfaction would help alleviate their burnout and mediate the influence of motives for selecting a teaching profession.

This study was conducted to compare the effect of bagging technique on the presence of pesticide residues in various parts of grape fruit (whole fruit, pulp and peel). The tested pesticides were diluted at 2,000 times and sprayed three times onto the crops at an interval of seven days and then they were collected at 0, 1, 3, 5 and 7 days after final application. Later, bagging/non-bagging samples were pre-treated with fruit, pulp and peel samples, respectively. Thiacloprid and lufenuron were not detected in any of the bagging samples. The thiacloprid residues of non-bagging samples in whole, peel and pulp samples were 0.47-1.09, 0.18-0.33 and 1.24-1.67 mg/kg, respectively. The lufenuron residues of non-bagging samples in whole fruit, peel and pulp samples were 0.16-0.62, < LOD-0.08 and 0.85-1.48 mg/kg, respectively. The biological half-lives of thiacloprid and lufenuron in whole fruit, peel and pulp of non-bagging samples were 5.7, 15.1 and 7.8 days and 4.0, 9.4 and 2.6 days, respectively. While the unbagged samples showed a sequential decrease in pesticide residues, this study concludes that bagging would be an effective method to protect the presence of thiacloprid and lufenuron residues in grape fruits.

This study tried to identify major factors which determine repurchase intentions. We consider customer satisfaction, service quality, switching cost and consumption emotions which are recently proposed in the related literatures. To test them empirically, we collected 374 questionnaires among 620 from corporate customers of major banks and 112 from employees of a major bank in corporate banking and analyzed them by LISREL 8.12.. The result of this study can be summed up as follows. First the most important determinant factor in repurchase intentions is customer satisfaction. Second, it is desirable to measure service quality not only in terms of 'process service quality', a process of service delivery to customers, but also 'outcome service quality', what customers receive from services or from service providers. Third, positive consumption emotions have positive influence upon customer satisfaction, negative consumption emotions have negative influence upon customer satisfaction and repurchase intentions. Fourth, switching cost, even though small in its influence, has been proved to be antecedent in repurchase intentions along with customer satisfaction and negative consumption emotions. As precedents in customers' repurchase intentions, customer satisfaction and process service quality are revealed to exercise the biggest influences. Also, positive consumption emotions, negative consumption emotions, outcome service quality and switching cost can be used as determinants in predicting corporate customers' repurchase intentions.

The experiment was conducted to study on the germination of seeds, and chemical change in the endorsperm and embryo of maize seeds treated with gibbrellic acid(GA) 25, G A 50, bengyl adenine(BA) 100 and B A 200 ppm. Obtained results can be summerized as follows: 1. The germination rate in the initial stage of maize seed increased most with G A 25 ppm treated but decreased most with B A 200 ppm treatment amount other treated blocks. There is no significant difference between treatments in the middle and later stage of the seed germination. 2. The quantity of Q $CO_2$ was noticeably increased together in parallel with germination at each blocks, but such fact was found that the block of treatment has low Q $CO_2$ in comparison with control and in particular, has the tendency to take very low in B A 200 ppm. 3. The amount of reducing sugar and total sugars among embryo and endosperm are promptly increased at each blocks, but B A treatment shows low rate of increase in comparison with the non treatment and G A treatment. 4. The quantity of crude protein of seed during germination are increased at the part of embryo and decreased at the part of endosperm. Such degree is most prominent in the treatment with G A 25 ppm and changing degree of treatment with 200 ppm is lowest.

A 67 years old male patient was admitted with back pain that had recurred from 6 months previously. Eleven years previously, he underwent stent grafting at the descending thoracic aorta for a chronic Stanford type B aortic dissection. The preoperative computed tomography showed aortic dissection from the origin of the left subclavian artery to the bifurcation of the abdominal aorta, and there was a type I endoleak at the proximal portion of the stent graft and aneurysmal dilatation of the descending aorta. A hybrid endovascular repair was successfully performed, and this involved debranching and rerouting the aortic arch vessels under extracorporeal cardiopulmonary bypass and then this was followed 13 days later by stenting in the ascending aorta, the aortic arch and the descending aorta. The postoperative computed tomography showed complete exclusion of the type I endoleak. After discharge, he has been followed up for 8 months without any problems.

The purpose of this study was to examine the influence of satisfaction with workplace child-care on the parenting stress, job commitment, and job satisfaction of parents. The questionnaires survey of this study was conducted on 185 parent-employees (97 fathers & 88 mothers) who used employer-supported child-care in the province of Kyungki-do. The results of this study were as follows: As the level of satisfaction with workplace child-care became higher, the level of parenting stress became lower. And as the level of satisfaction with workplace child-care became higher, the level of job commitment and job satisfaction became higher. Among five components of satisfaction with workplace child-care, satisfaction with the environment for child-care had an independent influence on parenting stress. And satisfaction with the management of child-care facility had an independent influence on job commitment and job satisfaction. This study suggested that education programs that target employers need to raise employers' awareness about the importance of workplace child-care in order to reduce parenting stress and to enhance job commitment and job satisfaction of parent-employees.
