  • Objective Categorical syndrome such as schizophrenia could be the complex of many continuous mental structure phenotypes including several personality development/degeneration dimensions. This is the study to search heritability and familiality of MMPI personality dimensions in the Korean schizophrenic LD (Linkage Disequilibrium) families. Methods We have recruited 204 probands (with schizophrenia) with their parents and siblings whenever possible. We have used MMPI questionnaires for measuring personality and symptomatic dimensions. Heritabilities of personality dimensions in total 543 family members were estimated using Sequential Oligogenic Linkage Analysis Routines (SOLAR). Personality dimensions in total family members were compared with those in 307 healthy unrelated controls for measuring the familialities using ANOVA analysis. Results Seven of the 10 MMPI variables were significantly heritable and were included in the subsequent analyses. The three groups (control, unaffected 1st degree relative, case) were found to be significantly different with the expected order of average group scores for all heritable dimensions. Conclusion Our results show that the aberrations in several personality dimensions could form the complexity of schizophrenic syndrome as a result of genetic-environment coactions or interactions in spite of some limitations (recruited family, phenotyping).

  • The current exploratory study attempted to investigate the levels of expected and perceived service quality of in-flight meals. A questionnaire was developed following extensive literature review and in-depth interviews. The survey was conducted on board a flight by international passengers and also by passengers in the trans lounge waiting for connecting flights between October 21, 2005 through October 30, 2005. Out of the 450 questionnaires administered, a total of 319 completed questionnaires were returned, yielding a response rate of 89.6%. The 20 items representing the service quality factor of in-flight meals were analyzed, resulting in four distinct dimensions-food quality, employee service, cleanliness and reliability. In all dimensions, customer expectation was higher than the perceived level of service and the service quality of Korean based airlines was higher than that compared to foreign based airlines. There were differences in the perceived service quality of in-flight meals according to the demographics of the respondents. The results of this study can be beneficial from a theoretical and practical point of view by providing empirical data that measures the service quality of in-flight meals.

  • Purpose - Multi-dimensional prices comprise multiple components such as monthly payments and a number of payments rather than a single lump-sum amount. According to previous studies, an increase in the number of price dimensions leads to a massive amount of cognitive stress resulting in incorrect calculation, and deterioration in the consistency of the price judgment. However, an increase only in the level of complexity of calculating multi-dimensional prices does not always result in a corresponding decrease in the accuracy of price evaluation. Since diverse variables could affect consumers' purchase-decision-making process, the results of price evaluation would be different. In this study, an empirical analysis was performed to determine how the accuracy of price evaluation varies depending on the extent of the complexity of price dimensions using product involvement and brand preference as moderating variables. Research design, data, and methodology - A survey was conducted on 260 students, and 252 effective responses were used for analysis. The data was analyzed using t-test, one-way ANOVA, and two-way ANOVA. In this study, six hypotheses were developed to examine the effect of product involvement and brand preference on consumers' evaluation effort of multi-dimensional prices. Results - As the number of price dimensions increased, accuracy of price evaluation appeared to be low in high involvement, as expected. However, it showed no differences in price evaluation effort when the level of complexity of calculating multi-dimensional prices is low. When a small number of price dimensions are presented in both cases of high and low involvement, accuracy of price evaluation is much higher in a weak brand preference. On the contrary, a strong brand preference enhances an accuracy of price evaluation only in case of low involvement when the number of price dimensions is increased. An interaction effect of product involvement and brand preference on consumers' evaluation of multi-dimensional prices did not exist irrespective of the level of complexity of calculating prices being high or low. Conclusions - When the number of price dimensions is small, consumers' effort for price evaluation shows almost no difference without the moderating effect of involvement, and a weak brand preference leads to a higher accuracy of price evaluation in an effort to make the best selection. No interaction effect of product involvement and brand preference was found except for a main effect of brand preference. When a price is composed of multiple dimensions rendering it more difficult to calculate the final price, the effort for price evaluation was expected to decrease only slightly in case of combination of high involvement and strong brand preference. This is because people have a higher purchase intentions and trust for that particular brand. However, the accuracy of price evaluation was much lower in cases of high involvement, and there was no interaction effect between product involvement and brand preference except for a main effect of involvement and brand preference, respectively.

  • Proper ergonomic design of a passenger seat for the highspeed train is one of the essential design components that is directly related to passenger comfort. This study investigated a systematic approach to the ergonomic passenger seat design and evaluation for the Korean highspeed train. To design an ergonomic passenger seat that improves passenger confort, Korean anthropometric data, pas- senger activities in the coach, body postures, body contours and seat dimensions were considered. By analyzing the interredlationship of such factors, resultant seat dimensions were suggested. To properly ecaluate the suggested dimensions, four prototypes were subsequently made and iteratively tested in the laboratory. It is expected that this approach is readily applicable to the passenger seat design of other transport vehicles as well as a train.

  • The purpose of this study is to develop Korean shoe-last based on the conformability of shoe. For this work, the important dimensions for the conformability of shoe were investigated and the systematic methods for evaluating the comfortable shoe were developed. Different two types of shoe-last for men and women were used in the experiment, respectively. 8000 feet dimensions of Korean adults were analyzed for developing standard shoe-last in this study. A total of 10 subjects (ranged from 21 to 25 years old) participated voluntarily. They evaluated each shoes made by developed shoe-last. A rating scale and description was used to express the degree of conformability. Also, 26 feet dimensions were measured using martin-typed gauge and footprint. The relationship between foot dimension and conformability of shoe was analyzed. As a result, Korean standard shoe-last was suggested based on the based on the conformability of shoe. The evaluating methods will be expected to help designer find more important design parameters. We will also expect that the standard shoe-last guarantee the optimal gait and minimal workload, especially in aspect of conformability.

  • This study shows how social presence(SP) dimensions influence online consumer's behavior in the social commerce(SC) context. It is expected that the results could be utilized in the development of SC websites. According to the results, the awareness and cognitive SP dimensions affected consumer trust, but affective SP did not. And then consumer trust toward SC websites as a belief affected attitude and intention of consumer. Thus, it was re-confirmed that a consecutive influential relationship in the theory of reasoned action, i.e., "belief-attitude-intention", was significant in SC context as well. Finally, it is required as a future research how to implement the awareness and cognitive SP dimensions in the SC websites.

  • This study examines the characteristics of consumers on the ambivalent clothing consuming behavior and the relationship of relevant variables. The data were obtained from 400 females over 20 years old who lived in the cities of Daejeon or Seoul in October in 2009. The values consist of four dimensions: success-oriented value, social value, family-oriented value, and individual value. Value-conscious consumption consists of two dimensions: emotional value-conscious consumption and functional value-conscious consumption. The aforementioned four dimensions of value have positive effects on ambivalent clothing consuming behavior. In addition, emotional value-conscious consumption has a significant relationship on all 5 types in ambivalent clothing consuming behavior. The findings of this study are expected to be used to find niche markets and establish advanced advertising strategies.
