This study designed and produced stimuli in the form of canned images of fun humor, character, quirky, and sexy humor, and measured the signal values (SI) of the hippocampus associated with memory through fMRI analysis. The results of 20 participants showed that there were differences in SI values according to gender and age, and the fun humor image stimuli had the highest SI values. Men showed higher SI values for fun humor image stimuli, while women showed higher SI values for character humor image stimuli. In addition, those in their 20s showed higher SI values for fun humor image stimuli, while those in their 30s showed higher SI values for quirky humor image stimuli. Considering these findings, it is expected that more effective results can be obtained by utilizing fun humor images and characters in package design.

The online shopping industry in China has experienced rapid growth, particularly in the infant goods sector, which is considered highly promising in terms of its growth potential. This growth can be attributed to the Chinese market's increasing economic power, the implementation of new policies concerning marriage and childbirth, changes in family structure, and evolving and diverse consumer demands for infant products. While the infant clothing industry has emerged as a significant player in the Chinese market, there is still a lack of sufficient academic research on the online shopping environment specific to China's infant clothing industry. The objective of this study was to explore the influence of online experiential marketing on brand loyalty and purchase intention among Chinese consumers of children's wear. The study findings indicated that the emotional experience, action experience, and relationship experience encountered by consumers during online interactions had a positive and significant impact on brand loyalty. Both perceptual experience and cognitive experience had a positive and significant influence on consumers' willingness to make a purchase. The study also revealed that brand loyalty had a positive and significant effect on consumers' purchase intention. The perception of online experiential marketing, brand loyalty, and purchase intention varied based on individual attributes, and gender was found to moderate the relationship between online experiential marketing and brand loyalty.

To design the cockpit of Korean helicopter, anthropometric data for Korean helicopter pilots as a target population is necessary. The present study measured the body sizes of Korean helicopter pilots to design the cockpit of Korean helicopter, and compared the measurements with those of Korean civilian and the US Army. The sample size was 100 which determined by a statistical analysis. Anthropometric measurements were collected for 100 samples (male = 94, female = 6; age group = 20~40) of Korean helicopter pilots by applying standard measurement protocol. To compare three anthropometric data, Korean civilian and US Army data were controlled by considering age group (20~40) and gender ratio (male: female = 9:1) of Korean helicopter pilots. The average body sizes of Korean helicopter pilots were mostly similar to those of Korean civilian, however, lower limb related variables (hip breadth, popliteal height and thigh clearance) and shoulder-to-elbow length were significantly greater (1~7%) at α=0.05. Furthermore, the average body sizes for Korean helicopter pilots regarding lower limb length and thickness were significantly smaller than those of the US Army (1~12%); however, the average body sizes for Korean helicopter pilots regarding upper body related variables (sitting height, sitting eye height, and acromial height) and hip breadth were significantly greater (0.7~1.9%). Lastly, size variability for Korean helicopter pilots was significantly smaller than those of Korean civilian and the US Army. Anthropometric data for Korean helicopter pilots of the present study was applied to design and evaluate a Korean helicopter cockpit.

Objectives: This study was conducted to estimate the unbiased smoking prevalence and its standard errors among adolescents in a large city in Korea, by design-based analysis. Methods: All the students in Daegu city were stratified by grade, gender and region, and then schools as primary sampling units (PSU) were selected by probability proportional to size (PPS) sampling. One or two classes were sampled randomly from each grade, from 5th grade in elementary schools to the 3rd grade in high schools. The students anonymously completed a standardized self-administered questionnaire from October to December 2004. The total number of respondents was 8,480 in the final analysis, excluding the third graders in the general high schools because of incomplete sampling. The sampling weight was calculated for each student after post-stratification adjustment, with adjustment being made for the missing cases. The data were analyzed with Stata 8.0 with consideration of PSU, weighting and the strata variables. Results: The smoking prevalence (%) and standard errors for male students from the fifth grade in elementary schools to the second grade in high schools were $0.93{\pm}0.47,\;1.83{\pm}0.74,\;3.16{\pm}1.00,\;5.12{\pm}1.02,\;10.86{\pm}1.13,\;15.63{\pm}2.44\;and\;17.96{\pm}2.67$, and those for the female students were $0.28{\pm}0.28,\;1.17{\pm}0.73,\;3.13{\pm}0.60,\;1.45{\pm}0.58,\;3.94{\pm}0.92,\;8.75{\pm}1.86\;and\;10.04{\pm}1.70$, sequentially. Conclusions: The smoking prevalence from this study was much higher than those from the other conventional studies conducted in Korea. The point estimates and standard errors from the design-based analysis were different from those of the model-based analysis. These findings suggest the importance of design-based analysis to estimate unbiased prevalence and standard errors in complex survey data and this method is recommended to apply to future surveys for determining the smoking prevalence for specific population.

With concerns for consumers' return behaviors affecting internet shopping malls' profits and product management in the internet clothing market, this study is designed to investigate determinants affecting return and path models for return behaviors. For an empirical study, questionnaires are prepared and respondents in their 20s and 30s with internet clothing purchase experience are selected using the convenience sampling. A total of 517 questionnaires are used for the final analysis. Data are analyzed by using SPSS 12.0 software and descriptive statistics, $x^2$-test, discriminant analysis, regression analysis, and path analysis is conducted. The results are as follows. First, ones who have returned after purchasing clothing items in internet shopping reached 63.4% of the total consumers. Respondents returned items with price at 50 thousand won or less stood at 67.2%, and the most frequent return shopping malls are open markets with their return rate at 51.1%. Second, variables such as risk perception, information search, impulse buying, buying experience, and age have a positive effect on return experience. Impulse buying and buying experience turn out to have a significant effect on the degree of return, but risk perception, information search, age, and gender to have an insignificant effect. Return intention is significantly affected by risk perception, gender, and age. Third, the analysis of path model for return experience shows that perceived risk has a positively effect, and information search has a direct effect as well as an indirect effect through buying experience or impulse buying. The analysis of path model for the degree of return shows that risk perception does not have effect, but information search has indirect effect through buying experience or impulse buying. This study is thought to find consumers' return behavior characteristics in online shopping, and help businesses operating online shopping malls to efficiently manage returns and set up strategies against returns.

Background : Traditional Korean medicine(TKM) has gained in popularity among chronic patients in recent years. The use of TKM among patients with chronic diseases is common, with about two thirds of patients using some form of TKM in Korea. Objectives : The purpose of this study is to analyze the use of TKM and determine what factors affect to use TKM among patients with chronic diseases. The study also aims to provide information on TKM therapies and assist therapy selection among various TKM therapies for patients with chronic diseases. Methods : The design of the study was descriptive cross-sectional, and data were collected using a 21-item questionnaire. This study was conducted with subjects with confirmed diagnosis of chronic diseases, who live in Jeju Province, Korea. Results : Among the participants, past or current TKM use was 66.7%, with a statistically significant difference in gender and level of health status groups(p<0.05), but no difference in age, marital status, education, occupation, and income groups. The most common therapies of TKM used by the patients included acupuncture(51.1%), physiotherapy(16.8%), cupping(13.5%), and herbal medicine(4.8%). The main benefits from TKM perceived by the patients were chronic diseases management and health promotion. In a logistic regression analysis, significant influencing factors related to TKM use were gender, family income level, the extent of recognition of efficacy, heath status, and health security program. Conclusions : In this study the socio-demographic and health status, recognition of TKM efficacy factors associated with TKM use among patients with chronic diseases were similar to those found in the general population. The findings suggest that due to the relatively high use of TKM among patients with chronic diseases in Korea, this topic should be taken into account in the development of a holistic approach for patients with chronic diseases and an efficient chronic disease management system. Additionally proactive and consistent management of TKM is necessary in the health care system in Korea.
