This study is designed to find out the effects of price on the consumers'perceived quality, value and purchase willingness of clothing in order to get the basic information that is needed in helping clothing manufacturer's strategy for merchandising promotion on price. This study was conducted by means of a questionnaire survey of university students in seoul. SAS program was used for analysis. The conclusions of this study as follow: first, with respect to the price level of clothing, consumers evaluate the perceived quality of high-price case higher than that of low-price case, and evaluate the perceived value and purchase willingness of low-price case higher than those of high-price case. Second, with respect to the brand name level of clothing, consumers evaluate the perceived quality, perceived value and purchase willingness of well-known brand case higher than those of unknown brand can. Third, the interaction between price and brand dosen't appear. Thus from this result we can know that price and brand have the same amount of effect in both single-quo case and multi-que case. Forth, with respect to the price and brand name level of clothing, there exist significant differences in perceived quality, perceived value, and brand name level. Fifth, in the study of the relationship between perceived quality and purchase willingness and the relationship between the perceived value and purchase willingness, perceived value has more effect on purchase willingness than perceived quality.

The purpose of this study is to identify poorly understood factors related to the recent rapid decline in fertility in Korean society. Along with Becker's child demand theory, personal psychological traits, such as independence, nurturance, and affiliation, were given special attention in this study. We examine the processes of resource transfers between married women and their parents on childbearing intention in order to verify the effects of both factors. Five hundred and seventy-six women in their early stage of marriage from the 2009 wave of the National Survey of Marriage and Childbirth were analyzed. Main results of the study are as follows. First, Becker's child demand theory is not supported. Instead, the women who were not given economic support from their parents in getting a residence at the time of their wedding turned out to be more willing to have a child, potentially because they were more independent. Second, the women who provided caretaking and emotional support to their parents had higher childbearing intentions, potentially because they were more nurturing. In conclusion, these personal psychological variables are important in understanding the childbearing behavior of women. We suggest that the government should pay more attention to the micro-personal factors raised in this study when executing policies to reverse the current trend of low fertility.

This research examines the causal relationships between supervisor trust and organizational citizenship behavior(OCB) and the mediating role of organizational trust on OCB. Using the sample of 282 small and medium sized enterprises' employees, this study analyzes three alternative hypotheses centered around supervisor trust, organizational trust, and OCB. The results show that supervisor trust has a strong positive effect on OCB. Second, organizational trust is positively related to OCB. Third, this research proves that partial mediating effects of organizational trust exist between supervisor trust(relational trust) and OCB(civic virtue, sportsmanship). Finally, this research proves that a full mediating effect of organizational trust exists between supervisor trust(calculative trust) and OCB(sportsmanship). This study recommends supervisor trust, organizational trust be valued in order to increase OCB vital for organizational effectiveness or productivity in small-medium sized manufacturing enterprises.

The purpose of the study was to investigate what kinds of learning strategies EFL learners use to learn English grammar and what is benefit from structured grammar input processing. Students of the study consisted of 48 college students who took Practical English Grammar at a university in Kyung-Gi area and were divided into two groups based on grammar scores. The students were asked to take two grammar tasks and grammar tests and complete a survey including questions on grammar strategy and input processing. The results of the study are as follows. First, learners' grammar level has an effect on use of grammar attack strategy including asking teachers, using grammar books and given contexts whereas there was no significant difference between groups in the planning strategies, Among memory strategies, using grammar exercise and linking with already known structure demonstrated a significant difference between groups. Second, with regard to input processing, high level students got higher score on how much they understood the structured grammar input compared with low level students. Third, explicit implicit instruction added to input processing seems more comprehensible and more available than structured input only, Finally, it showed that there is positive relationship between perception and score of input processing tasks and grammar tests. Especially, learners' perception of input processing correlated more with final tests and tasks. Therefore, it suggests that the more input processing task need to develop and utilize in order to facilitate learners' intake.

Nitrile-forming eliminations from (E)-2,4-$(NO_2)_2C_6H_2CH=NOC_6H_4-2-X-4-NO_2$ (1a-e) promoted by $R_3N$ in MeCN have been studied kinetically. The reactions are second-order and exhibit Br$\ddot{o}$nsted ${\beta}$ = 0.83-1.0 and ${\mid}{\beta}_{lg}{\mid}$ = 0.41-0.46. The results have been interpreted in terms of highly E1cb-like transition state with extensive $C_{\beta}$-H bond cleavage and limited $N_{\alpha}$-OAr bond cleavage. Comparison with existing data reveals that the structure of the transition state changes from E2-central to highly E1cb-like either by the change of the ${\beta}$-aryl group from Ph to 2,4-dinitrophenyl under the same condition or by the base-solvent system variation from $EtO^-$-EtOH to $Et_3N$-MeCN for a given substrate (1a-e).

In this present study, bagasse based pulp and paper industry wastewater was treated under different operating conditions such as initial pH (6-8), temperature ($25-35^{\circ}C$) and contact time (3-7 days) by using Bacillus subtilis. Response surface methodology (RSM) coupled with Box-Behnken response surface design (BBD) was employed to investigate the effect of process variables on the responses such as turbidity, biological oxygen demand (BOD) and chemical oxygen demand (COD) removal. The experimental data were analyzed by Pareto analysis of variance (ANOVA) and the second order polynomial models were developed. Interactive effects of the process variables on the responses were studied using plotting 3D response surface contour graph and the optimum process conditions were found to be: initial pH of 7, temperature of $30^{\circ}C$ and contact time of 5 days. Under these conditions, removal efficiencies of turbidity, BOD and COD were found to be 85%, 93% and 80% respectively which are close agreement with real experiments. These results indicate that the treatment of bagasse based pulp and paper industry wastewater using Bacillus subtilis is an effective and novel technique.

This study deals with the roundabout traffic accidents by traffic impeding factor. The purpose of this study is to comparatively analyze the characteristics of accidents and to develop the accident models. In pursuing the above, this study used a statistical program SPSS 20.0 to analyze 2,342 accidents occurred within 79 roundabouts in Korea. The main results are as follows. First, 4 accident models which were all statistically significant were developed. Second, the traffic volume and width of right-turn-only lane were analyzed to be common variable in the bus stop related models. The variables such as right-turn-only lane, street light, turning radius of entry lane were selected as specific variables. Especially street light and turning radius of entry lane were evaluated to have negative effects to the accidents. It is, therefore, essential to install the street light and place a sufficient turning radius in order to reduce the roundabout accidents. Finally, the traffic volume and number of entry lane were analyzed to be common variable in the on-street parking related models. Also, the width of right-turn-only lane and bus stop were evaluate to be specific variables in the model with on-street parking. This can be expected to give some implications to making the accident reduction guidelines.

Objective: This study examined the relationships among teachers' empathy ability, children's peer competence and teacher-child relationships. Methods: 180 teachers and 360 children from 3 to 5 years old were included in the study. The research variables were measured by teachers' self-report through questionnaires. The collected data were analyzed by t-test, one-way ANOVA, and three-step mediated regression analysis. Results: First, teachers' empathy ability and teacher-child relationship showed significant differences according to teacher variables (age, marital status, parental status). And children's peer competence was significantly different according to gender. Second, intimacy which was a subfactor of teacher-child relationships showed a perfect mediating role in the association between teachers' empathy ability and peer competence. Conclusion/Implications: These results suggest the importance of teacher-child's intimate relationships since it affects the child's peer competence significantly. In this study, it was found that, in order to help foster the teacher's empathic ability and teacher-child relationships which have positive effects on the child's desirable peer formation, continuous teacher education and diverse studies are needed.

The hotel industry needs to make the competitive advantage difficult to be imitated in order to remain sustainable in competitive business circumstances. Front-line employees' service-oriented citizenship behaviors(OCBs) can be such a strength from the perspective of organizational system. With an aim of investigating the antecedents of the hotel front-line employees' service-oriented OCBs, this study proposed a theoretical framework linking authentic leadership to service-oriented OCBs with goal commitment as a mediator. A total of 260 cases without missing values have been used for the final analysis and structural equation modeling (SEM) is employed using the SPSS and AMOS 7. It was first found that self-awareness and relational transparency of authentic leadership made a significant impact on their goal commitment while balanced processing and moral perspective failed to influence them. Second. goal commitment influenced all sub-factors of service-oriented OCBs. Third, moral perspective and relational transparency of authentic leadership significantly influenced service-oriented OCBs while self-awareness and relational transparency failed to make it. Finally, goal commitment significantly makes an intervening effect for the relationship between self-awareness & service-oriented OCBs and relational transparency & service-oriented OCBs but failed to intervene the other relationships. The results provide theoretical and practical implications regarding directions of leadership styles and HR management in the hotel industry and suggestions for the further extended studies.

The purpose of this study was to apply the learning clinic program to the maladjusted children to help the cognitive processing style, sense type and learning strategy. The results were as follows. First, the cognitive processing style of low-grade elementary school children is divided into the concept of sequential low-order style, which analyzes information sequentially and consecutively, concrete thinking style that processes real and direct information coming in from outside, and invisible principle or information. The abstract cognitive thinking style improved after the process before the program proceeded. However, There was no meaningful result in the simultaneous processing cognitive style which had excellent intuition and emotion and likes change. Second, the temporal lobe in which the linguistic activity is viewed, heard and spoken in the sensory type, the function of the occipital lobe in which the character or the language is processed is improved, but the function of the parietal lobe in moving and manipulating the body is not significant. Finally, factors that contribute to learning such as sincerity, learning initiative, study method, study habits, and concentration are helpful in learning and school life.
