Purpose This study investigated the impact of review language style (affective vs. cognitive) on review helpfulness and the moderating effects of the types of attractions in the relationships between the review language and its helpfulness. Design/methodology/approach This study investigates the impact of review language style (affective vs. cognitive) on review helpfulness and the moderating effects of the types of attractions in the relationships between the review language and its helpfulness. This study selected two hedonic and utilitarian attractions (Hedonic: Brandenburg Gate, Utilitarian: Peragamon Museum) located in Berlin. A total of 3,320 reviews was collected from TripAdvisor. We divided online reviews posted for these places into reviews with more affective language and with more cognitive language by using the LIWC. Then, we investigated the impact of language effect on review helpfulness across the attraction type. Findings The findings suggest that peers tend to judge more helpful toward cognitive language in attraction reviews regardless of attraction type. This study found that peers tend to perceive more helpful toward cognitive review in utilitarian attractions. Even though there was an interaction effect between review language and attraction type, in hedonic attractions, the influence of cognitive language was reduced, but still cognitive reviews would get more helpful votes.

Learning analytic has been utilized to helps us to successfully complete the course by using the interaction of the teacher and the learner data generated from the teaching and learning support system. In other words, Learning analytic is a method in order to understand the activities of learners. In the learning analytic, the data model is needed in order to utilize the more useful for teaching and learning activities data. Therefore, in this study, we propose a user centric data model of learning styles and learning objects. This model is expressed by aggregating of user learning style, learning objects, and learning activities. The proposed model is significant that laid the foundation for analyzing the activities of the learners in course units.

The purpose of this study was to determine the effects of flower decorations on job stress and stress copying style of police officers. Flower decorations were done in the form of "one-table one-flower", in which flowers were placed on each desk in the office space. By analyzing color psychology, we first identified the symbolism of color, and selected the cut flowers in the same color. We selected six types of flowers in six colors: red, orange, yellow, green, blue and purple. Each Monday morning, the flower decorations were delivered to the police station. We selected 50 subjects who wanted to keep flowers on their desks every week as the experimental group and 44 subjects who only wanted to participated in the assessment as the control group. Before and after the program, we examined the mean difference between the control group and experimental group. After six sessions of the program, there was a significant difference in job stress (p < .001) and stress copying style (p = .049) of the experimental group compared to the control group. Therefore, this study proved that having flower decorations in an office space is effective for the psychological stability of police officers that are highly stressed, due to sensory stimulations from the colors and scents of flowers as well as mutual interaction as they take care of the flowers.

It is important for firms to help customers find the products or information they need in order to increase sales and promote return visits to their websites. Hence, the presentation of product information is very important in e-commerce websites. In this research, we study how disposition styles can influence browsing patterns. The test results show that people are inclined to use feature information paths in the vertical disposition style and product information paths in the horizontal disposition style. With vertical disposition, users are more likely to follow feature information paths which may help them focus on comparisons across products.

We present a client-server system architecture for inferring genetic interaction networks based on Bayesian networks. It is typical to take tens of hours when genome-wide large-scale genetic interaction networks are inferred in the form of Bayesian networks. To deal with this situation, batch-style distributed system architectures are preferable to interactive standalone architectures. Thus, we have implemented a loosely coupled client-server system for network inference and user interface. The network inference consists of two stages. Firstly, the proposed method divides a whole gene set into overlapped modules, based on biological annotations and expression data together. Secondly, it infers Bayesian networks for each module, and integrates the learned subnetworks to a global network through common genes across the modules.

Objectives : This study aimed to test potential modifying effects of education on the association between apolipoprotein E ${\varepsilon}4$ (Apo E4) and cognitive decline. Methods : A community cohort(N=683) aged 65 or over completed the Korean version of Mini-Mental State Examination(MMSE-K) at baseline and two years later(1999-2001). Apo E polymorphisms were genotyped, and classified into that with or without Apo E4. Educational levels were categorized into people with or without education. Covariates included demographic(age, gender), life style(smoking, alcohol drinking), clinical (depression, sleep disorder, vascular risk factors) characteristics. Results : The association between Apo E4 and cognitive decline was significant only in the old persons with no education. The interaction term between education and Apo E4 on cognitive decline was significant(p=0.040). Conclusion : Elders with no education might be more vulnerable to the impact of Apo E4 on cognitive decline, which suggests gene-environment interaction.

The current study observes the durational interaction of tautosyllabic consonants and vowels in the word-initial position of English and Korean child-directed speech (CDS). The effect of phonological laryngeal contrasts in stops on the following vowel duration, and the effect of the intrinsic vowel duration on the release duration of preceding stops in addition to the acoustic realization of the contrastive segments are explored in different prosodic contexts - phrase-initial/medial, focal accented/non-focused - in a marked speech style of CDS. A trade-off relationship between Voice Onset Time (VOT), as consonant release duration, and voicing phonation time, as vowel duration, reported from adult-to-adult speech, and patterns of durational variability are investigated in CDS of two languages with different linguistic rhythms, under systematically controlled prosodic contexts. Speech data were collected from four native English mothers and four native Korean mothers who were talking to their one-word staged infants. In addition to the acoustic measurements, the transformed delta measure is employed as a variability index of individual tokens. Results confirm the durational correlation between prevocalic consonants and following vowels. The interaction is revealed in a compensatory pattern such as longer VOTs followed by shorter vowel durations in both languages. An asymmetry is found in CV interaction in that the effect of consonant on vowel duration is greater than the VOT differences induced by the vowel. Prosodic effects are found such that the acoustic difference is enhanced between the contrastive segments under focal accent, supporting the paradigmatic strengthening effect. Positional variation, however, does not show any systematic effects on the variations of the measured acoustic quantities. Overall vowel duration and syllable duration are longer in English tokens but involve less variability across the prosodic variations. The constancy of syllable duration, therefore, is not found to be more strongly sustained in Korean CDS. The stylistic variation is discussed in relation to the listener under linguistic development in CDS.

The 21st century could be called the age of Experience Economy associated with the importance to external and internal experience of product users. It needs the understanding of customer's needs in new point of view. In the area of design development, it requires the extensive application of experience from traditional method that was based on the style and usability to more advanced concept. To correspond to these changes, we need to explore new customer's value system for knowledge-information design and systematic approaches to experience system. The purpose of this research is to define the concept of 'experience' newly in the importance side of customer's life, form a clear definition of experience design and present the model of application system. Theoretical frameworks of this research are based on the Empiricism and John Dewey's theory. By applying these frameworks make dear the concept of experience concept and reanalysis the meaning and style in the perspective of design. In this process, we can extract the main factors that inducing the experience, create new application system and model again to the field of design. Application model can creates various experiences through supplying different experience style and factors for customer, make customer realize experience object. Experience designs offer optimal experience to users by making a plan and design experience to user's goal.

Adolescence is a period of transition from child to adult and is a very important period in which to think about the direction to go in the future and establish one's ego. However, the level of life satisfaction experienced by Korean youths in the adolescent period has been shown to be the lowest among OECD countries. It is very critical to understand which factors are important in determining the level of life satisfaction and how they affect it. In this study, to analyze the factors which affect the life satisfaction of youths and their learning attitude - essential school activity prior to life satisfaction in the youth period, we firstly focused on the relationships with their parents, peers and teachers as potential factors affecting their learning attitude and life satisfaction. This study found that Parenting Style, Peer Attachment and Relationship with Teachers significantly influenced Life Satisfaction either directly or indirectly. We analyzed the structural relationships among these factors using the structure equation model, discussed the analysis results and concluded with further research directions.

The purpose of this study was to examine the effect of hair style and hair color on women's impression formation. The experimental design was $2{\times}3{\times}3$ (hair wave$\times$hair length$\times$hair color) factorial design by 3 independent variables. Subjects were 343 women in Seoul. Four factors were derived to account for the dimensions of impression formation. These were neatness, sociability, attractiveness, and femininity. The straight hairs were evaluated neater than the permed hairs, and the permed hairs were evaluated higher in sociability and attractiveness. The short hairs were perceived highest in sociability, and the long hairs were perceived high in attractiveness and femininity. The black hairs were perceived highest in neatness, the bright brown were perceived high in sociability and attractiveness, and dark brown were perceived high in femininity. Attractiveness had significant interaction effects depending on three independent variables: hair wave, lengths, and colors. Long black straight hair was perceived most attractive, and midium length black straight hair was least attractive. The light brown permed hairs were perceived high in attractiveness regardless of hair length. In the case of straight hair, the longer the hair length was, the younger the object women were perceived. The women with the long permed hair were perceived older than the women with short and midium length permed hair.
