Price discount is one of the commonly used promotion strategies to increase sales and revenue. If a discount is perceived before the purchase (i.e., pre-purchase discount), consumers are likely to perceive it as a potential gain. If it is noticed after making a regular-priced purchase (i.e., post-purchase discount), consumers may develop negative emotions and attitudes. Based on the rising transparency and omnipresence of price and discount information through web and mobile platforms, we attempt to tackle an understudied topic on the negative effect of post-purchase price discount. Specifically, post-purchase discount information may increase consumers' perception of monetary loss, which may affect consumers' decision to return the product, potentially increasing the operating costs borne by retailers. Based on a close scrutinization of the current market environment and previous academic literature, we suggest a novel conceptual framework to understand consumers' perception, attitude, and behavior (perception of loss, willingness to return) upon perceiving various formats of discount promotion (absolute value vs. percentage discount) posterior to the purchase of a product. We also look at the effect of price level (low-priced vs. high-priced). For marketing practitioners, we intend to suggest optimal promotion formats that can alleviate consumers' negative perceptions and prevent additional operation costs.

This study is a survey research for adult men in their from 20's to 50's. The purpose of this study is to find out that demographic characteristic, material knowledge, and purchase price have what effect on the selection behavior and the post-purchase satisfaction. The results are as follows. The purchase place according to demographic characteristic showed the significant difference in ages, monthly income, and occupation. The purchase amount per a dress suit and the having quantity of dress suits showed the significant difference according to all demographic characteristics. The importance of an selective criteria in case of selecting dress suits showed the partly significant difference according to demographic characteristics. The post-purchase satisfaction showed the no significant difference according to demographic characteristics, but showed the significant difference according to the knowledge degree for materials and purchase amounts. The interaction effect among demographic characteristics, the degree of knowledge for materials, and the purchase amount showed frequently the significant difference between two variables. The factor which have most greatly an effect on post-purchase satisfaction of menswear was the degree of knowledge for materials.

This paper presents the shear strengthening effect of externally post-tensioning (EPT) method using high-strength steel rod in pre-cracked reinforced concrete (RC) beams. Three- and four-point bending tests were performed on a total of 8 specimens by adjusting the strengthening depths in the deviator position of EPT. The effective strengthening depths were 435, 535, and 610 mm. The pre-loading up to about 2/3 of ultimate load capacity measured in unstrengthened RC beam were applied in the beam to be post-tensioned. The EPT method was then applied to the pre-damaged RC beams and re-loading was added until the end of the test. EPT restored deflections of 3 mm or more, which account for about 40% of deflection when the pre-loading was applied. The shear strengthening increases more than 3 times and 36~107% in terms of the stiffness and load-carrying capacity compared to unstrengthening RC beams. The increased load-carrying capacities of the post-tensioned beam with strengthening depths of 435 and 535 mm are almost the same as 36~61%, and those of 610 mm are 84~107%, which shows the greatest shear strengthening effect.

This study identified the relationship between deliberate rumination of adults who experienced traumas and post-traumatic growth, and examined the mediating model of meaning of life moderated by trauma intensity on deliberate rumination and post-traumatic growth. Participants were 318 male and female adults who experienced traumas. The moderated mediating effect was analysed with PROCESS Macro 3.5 Model 7. Results revealed that deliberate rumination of adults who experienced traumas was positively correlated with trauma intensity, meaning of life, and post-traumatic growth, while meaning of life was positively correlated with post-traumatic growth. In a moderated mediating model for post-traumatic growth, there was significant interaction effect of deliberate rumination and trauma intensity; conditionally indirect effect of deliberate rumination was only significant for whose trauma intensity were high. These findings suggest that adults who did deliberate rumination are more likely to experience post-traumatic growth with finding meaning of life. And, the moderating effect suggests that this influence is only with higher levels of trauma intensity. In conclusion, deliberate rumination of severe traumatic event may lead to post-traumatic growth, and it can be helpful to experience the meaning of life in the process.

The price stabilization policies which require the underwriters to maintain post-IPO prices at some level (stabilization duty) or give put-back options to investors, have survived for eight years until June, 2006. The purpose of this study is to analyze the effect of price stabilization policies upon IPO underpricing in KOSDAQ. The study decomposes the influence of the price stabilization policies on IPO underpricing into ex-ante and ex-post effect. The price stabilization policies have shown to increase the IPO underpricing both at ex-ante and ex post bases. And the ex-ante effect is greater than ex-post effect. Among policies, the price stabilization duty magnifies the underpricing more than put-back option. This study differentiate from the precedented studies by including the whole period in which those policies are in act and by decomposing the IPO underpricing effects into ex-ante and ex-post bases.

This study compared the effects of craniocervical flexion exercise with conservative cervical flexion exercise in workers with chronic neck pain. Subjects were randomly allocated to two groups: control (n=20) and experimental group (n=20), respectively. The conservative exercise for the control group consisted of cervical flexion exercise, whereas the experimental group performed a craniocervical flexion exercise. To compare the two groups, the visual analogue scale (VAS) for a pain, neck disability index (NDI) for a neck disability scale, and cross sectional area (CSA) of longus colli muscle using ultrasound image were assessed on pre-intervention, post-intervention, and 2 weeks follow-up. 2-way repeated ANOVA was used with Bonferroni post-hoc test. (1) There were significant main effects (within and between groups) (p<0.05) and interaction effect (p<0.05) in VAS. Post-hoc test revealed that there were significant differences in all pair-wise comparisons. (2) There were significant main effects (within and between groups) (p<0.05) and interaction effect (p<0.05) in NDI. Post-hoc test revealed that there were significant differences between pre-intervention and post-intervention, pre-intervention and 2 weeks follow-up. (3) There were significant main effects (within and between groups) (p<0.05) and interaction effect (p<0.05) in CSA of longus colli muscle. Post-hoc test revealed that there were significant differences in all pair-wise comparisons. The findings indicate that craniocervical flexion exercise are more effective for improving pain, neck disability, and CSA of longus colli muscle than cervical flexion exercise in workers with chronic neck pain.

We have investigated the biological effects of recombinant IL-1$\beta$ (rIL-1$\beta$) on the expression of antiviral genes such as Myxovirus-3 (MX-3) and Interferon regulating factor-1 (IRF-1), which are related to type I interferon. When ten micrograms of rIL-1$\beta$ were treated, we observed the stimulatory effect on the expression of these antiviral genes. Interestingly, at the early stage of stimulation, these genes were down-regulated and then up-regulated by the results obtained that the expressions of these genes were decreased at day 1 post-injection and gradually increased at day 3 post-injection. Thus, the stimulatory effect of rIL-1$\beta$ on the expression of MX-3 and IRF-3 gene might be an indirect stimulatory effect because significant up-regulation was delayed until day 3 post-injection.

Purpose: Meta-analysis of this study was to analyze the character of adolescent smoking cessation programs, to calculate the effect size according to variables and to compare the weighted mean effect sizes on adolescent smoking cessation programs in Korea. Methods: Twenty two studies for meta-analysis were selected from dissertations, theses, articles and research papers that had been published from 1995 to 2003. The selected studies had a randomized or nonequivalent control group in a pretest-post test design and had reported statistical value to calculate the effect size. Results: The mean number of sessions was 6.5. The education time per each session varied from 40 to 150 min and the most applied theories were Bandura's social-cognitive theory and the cognitive-behavioral theory. Smoking-knowledge, smoking-attitudes and smoking-amount showed high effects on the first post test after mediating adolescent smoking cessation programs according to the criteria of Cohen. The effect size of urine-cotinine found no homogeneity on the first post test, but it was significantly effective on the second post test. Conclusion: Adolescent smoking cessation programs analyzed in this study were relatively effective in smoking abstinence.

The post-antibiotic effect (PAE), which is defined as the period of time lag that the target organisms resume normal growth rate after complete removal of the antibiotics, of LB 20304 and ciprofloxacin was evaluated against Staphylococcus aureus 6538p and Escherichia coli 3190Y, respectively. The PAE was estimated by adding each antibiotic to a log phase of growth and incubating at $37^{\circ}$C for 1 h.Antibiotic was removed by centrifugation, and total viable cell counts were determined hourly for a further 10 h. The PAEs of LB20304 against S. aureus at concentrations of $1{\times}MIC\;and\;2{\mu}g/ml$ were 10 min and 93min, respectively. LB20304 showed a comparable PAE to ciprofloxacin. Against E. coli, the PAE of LB20304 was also similar to that of ciprofloxacin at concentration of $4{\times}MIC$ but it was much longer than that of ciprofloxacin at concentration of 2${\mu}g/ml$. LB20304 showed higher lethality than ciprofloxacin against both S. aureus and E. coli strains.

Purpose: This study was conducted to test the effect of a 5 weeks health education program on stroke for rural elderly people. Methods: A total of 55 rural elders in Kok Sung County were participated in the health education on stroke program. Descriptive statistics, and paired t-test were used for statistical analysis with SPSS 12.0. Results: The results are summarized as follows : Mean age was 67.3 years and 88.2% of participants were female. The mean pre-test scores for knowledge of stroke were 0.35 and post-test, 0.85 (p< .001). Percentage of accurate response rates of warning signs of stroke were sudden dizziness pre-test 45.5% post-test 80.0%, sudden trouble speaking or understanding, pre-test 27.3% post-test 41.8%, sudden trouble walking, loss of balance or coordination, pre-test 32.7% post-test 70.9%, sudden numbness or weakness of the arm or leg, especially on one side of the body, pre-test 47.3% post-test 72.7%, sudden confusion, pre-test 27.3% post-test 81.8%, sudden numbness or weakness of the face especially on one side of the body, pre-test 40.0% post-test 76.4%, sudden severe headache with no known cause, pre-test 40.0% post-test 70.9%, Sudden trouble seeing in one or both eyes, pre-test 38.1% post-test 66.0%, nausea or vomiting pre-test 16.4% post-test 43.6%. The increases after the health education on stroke were statistically significant. Conclusions: Health education on stroke for rural elderly people are needed and should focus on community health care programs, especially for those who are older, had a low level of education, and low socio-economical status.
