  • The purpose of this research is to investigate the mother and teachers need assessment for preschooler consumer education and related variables and to provide a basis for the development of consumer education program. The survey of this research was conducted by means of self-administered questionnaire with 302 mothers of the preschoolers who are 4-5 years old and attend nursery and kindergarten and 221 teachers of nursery and kindergarten in Ulsan. The statistics used for data analysis are frequencies and percentage, mean and standard deviation, on way ANOVA and Scheffee-test, Person's correlation using the SPSS/PC+ program. Some conclusions from the above investigation are as follows: 1. Each level of the need for consumer education on 22 subject area perceived by mothers and teachers of preschoolers was high and relatively high. Thus consumer education program for preschooler must include all subject area. 2. The mother's need for preschooler consumer education differs significantly according to age. The teacher's need for preschooler consumer education differs significantly according to family income. But these variables take a little effect to the need of mother and teacher. So the consumer education program doesn't need to classify by socio-economic characteristics of mother and teacher. 3. The mother's need for preschooler consumer education are positively correlated to consumer knowledge and consumer skill but negatively correlated to consumption oriented attitude. So the consumer education program needs to develop the consumer knowledge and skill and reduce consumption oriented attitude for the preschooler's mother. 4. The teacher's need for preschooler consumer education are positively correlated to the level of consumer role performance. Thus the reeducation program for the teacher needs to develop the consumer role performance.

  • Purpose - With growing competition in the service distribution industry, the importance of managing customer complaints has increased. If firms handle customer complaints effectively, they can strengthen customer loyalty and repurchase intention. Many studies have focused on customers expressing complaints, yet research on silent customers is scant. This study focuses on two types of complainers and non-complainers. In other words, this study is to examine the value of voice complaint intention and no-action intention. This study also investigates how perceptual and relational factors affect complaint intention. Research design, data, and methodology - This study was carried out using the survey with undergraduate students who have faced a service failure in a retail store(fast foods, electronics, apparel). And if such complaint were to occur again, respondents were asked about any possible action they would take. 300 questionnaires were distributed and a total of 279 respondents provided complete and usable data. The sample consisted of 158 males(56.6%) and 121 females(43.4%). The structural equation modeling analysis was used for the hypothesis test. Results - The results are as follows. First, attitude toward complaining, likelihood of successful complaint, and ease of complaint were positively related to voice complaint intention. Second, attitude toward complaining, likelihood of successful complaint, and ease of complaint were negatively related to no-action intention. Third, commitment was positively related to voice complaint intention but didn't have a significant negative impact on no action. Forth, voice complaint behavior reduced switching intention and no-action intention enhanced switching intention. Conclusions - The findings of this study confirm the value of complaint behavior and show voice complaint intention and no-action intention should be managed differently. Voice complaint intention is evaluated positively because it reflects customers' concerns about the company, while no-action intention is evaluated negatively. Attitude toward complaing is the most effective in increasing voice complaint intention and likelihood of successful complaint is a major factor in reducing no-action intention. Also, in explaining switching intention, voice complaint intention plays a more important role than no-action intention.

  • Objectives: The internal adaptation of composite restorations with or without resin modified glass ionomer cement (RMGIC) was analyzed non-destructively using Microcomputed tomography (micro-CT). Materials and Methods: Thirty intact human teeth were used. The specimens were divided into 3 groups. In the control group, the cavities were etched with 10% phosphoric acid for 15 sec. Composite resin was filled into the cavity without adhesive. In group 1, light cured glass ionomer cement (GIC, Fuji II LC, GC) was applied as a base. The cavities were then etched, bonded, light cured and filled with composites. In group 2, the cavities were then etched, bonded, light cured and filled with composites without base application. They were immersed in a 25% silver nitrate solution. Micro-CT was performed before and after mechanical loading. One-way ANOVA with Duncan analysis was used to compare the internal adaptation between the groups before or after loading. A paired t-test was used to compare internal adaptation before and after mechanical loading. All statistical inferences were made within the 95% confidence interval. Results: The silver nitrate solution successfully penetrated into the dentinal tubules from the pulp spaces, and infiltrated into the gap between restoration and pulpal floor. Group 2 showed a lower adaptation than the control group and group 1 (p < 0.05). There was no significant difference between the control group and group 1. For all groups, there was a significant difference between before and after mechanical loading (p < 0.05). Conclusions: The internal adaptation before and after loading was better when composites were bonded to tooth using adhesive than composites based with RMGIC.

  • The purpose of this study is to compare food habits of four institution(public boarding home, public mursing home, private boarding home, meal service in welfare center) in Pusan, Korea. Data were collected from 119 of were more than 65 years in the above institutions. Chi-square test was the main data analysis method. More than a quarter of the respondents(27%) showed fairly good level of activity, while a half of them(52.9%) answered the middle level. More than 80 percent of the respondents reported that their food attitude was "Good". There were more elderly women than elderly men among the four institutions. Although the four institutions have served snacks on the regular basis, they did not provide the residents with nutritious food. Most of the residents want to have snacks between meals, but they did not perfer candy. All the subjects didn't point out any particular problem of institution. They were accustomed with their old food served by their institution. As food perferences, almost all of the respondents preferred cooked rice and cooked rice with cereals. Only the residents of private boaring home liked cooked rice with red bean. In case of soup, all of residents liked any kind of soup. The most preferred most menu was beef. But only residents of private boarding home did not like pork. All residents like any all kind of kimchi except kimchi made by radish. In preference of cooking method of a side dish, seasoned food and vegetables were the most favorable menu by the respondents. Compared to the private home, the institutions give residents effective plan to prepare meals. Even though this study tried to find differences in attitudes of dietary life among the institutions, it could not find any meaningful difference among them. Korean elders in the institutions seem to have no proper that they do not have any proper sense of evaluating their dietary life.

  • The plastic hinge region of RC pier ensures its nonlinear behavior during strong earthquake events. It is assumed that the piers secure sufficient strength and ductility in order to prevent the collapse of the bridge during strong earthquake. However, the presence of a lap-splice of longitudinal bars in the plastic hinge region may lead to the occurrence of early bond failure in the lap-splice zone and result in significant loss of the seismic performance. The current regulations for seismic performance evaluation limit the ultimate strain and displacement ductility considering the eventual presence of lap-splice, but do not consider the lap-splice length. In this study, seismic performance test and analysis are performed according to the cross-sectional size and the lap-splice length in the case of longitudinal bars with lap-splice located in the plastic hinge region of existing RC bridge columns with circular cross-section. The seismic behavioral characteristics of the piers are also analyzed. Based upon the results, this paper presents a more reasonable seismic performance evaluation method considering the lap-splice length and the cross-sectional size of the column.
