  • By examining variables affecting university student's perceptions of marriage, this study aimed to better understand how to promote positive perceptions of marriage among university students. The study sample consisted of 488 university students and their parents in Incheon and Gyeonggi, Korea. For data analysis, t-test, correlation analysis, and hierarchical regression analysis were performed. First, results showed that individual growth, emotional stability, and overall perceptions of marriage varied by gender. And results showed that individual growth, institutional necessity, and overall perceptions of marriage varied by grade. Second, higher levels of perceptions of marriage among university students were significantly correlated with greater university student's identity, better parent's marital relationship. Third, the personal relations was most influential variable on university student's perceptions of marriage, followed by the parent's conflict and authority the mother's duties, followed by the target orientating, gender and grade. Overall, results suggest that parent's marital relationship is important for promotion of positive perceptions of marriage among university students.

  • The purpose of this study was to find research trends of smart learning. For this, we identified the research's characteristics such as the subject or keyword of research, method, data collection, and statistical analysis method. The 2,865 articles published from 1995 to 2013 were gathered from five Korean academic journals related to smart learning. Among them, research keyword, areas, research method, data collection method, and statistical analysis method were analyzed on 596 papers. The findings of this study were as follows: (a) Smart learning papers such keyword likes u-learning, m-learning, and smart-learning were emerging after 2006. Smart learning papers with ICT related topics were highly increased after 2000, but they were decreased after 2006. Smart learning papers with e-learning related keywords were steadily increased after 2000 through 2013. (b) The research field of deign had the highest portion in smart learning research, but managing had the lowest portion. (c) Development was mainly used as a research method. Both questionnaire and experiment were mainly used for collecting data methods. T-test and frequency analysis were mainly used as statistical analysis methods.

  • Word-of-mouth (WOM) communication (traditionally important in consumption) is expanding its influence into cyber space and is playing an important role in online shopping. Consumers who use online shopping might not readily make purchasing decisions due to information overload, lack of accurate product recognition, and the distrust of commercial information. Subsequently, people use WOM communication for a mutual interchange with others who share common concerns, interests, and purposes. This study examines the consumer characteristics, perceived risk on online shopping and benefits of online shopping according to WOM behavior that may significantly affect consumer actions. Factor analysis, t-test, one-way ANOVA, cluster analysis, and Chi-square analysis were used for statistical analysis to identify the differences in consumer characteristics. Online WOM behavior consumers purchased more various items than offline WOM behavior consumers; however, the most influential purchasing factor was price regardless of WOM behavior. Offline WOM behavior consumers have shown higher perceived online shopping risks and benefits.

  • This study considered network quotient (NQ) of deluxe hotel employees and schematized characteristic attributes of being selected by employees with image through correspondence analysis in terms of cognition degree. Self-administrated questionnaires were completed by employees (292 samples) and data were analysed by frequency, t-test, one-way ANOVA, reliability and correspondence analysis. First, the hotel employees indicated the high average value in "participating in special education or seminar for improving ability ($3.85{\pm}0.76$). Second, as a result of analyzing difference according to gender, the average value in men was higher than in women. It was indicated that the higher age and career lead to a rise even in the average value of relationship index. Third, in consequence of carrying out correspondence analysis in order to prepare image map according to cognition level on relationship index in hotel employees, the measurement item that is placed in the closest distance to the response as saying of not so very was the response as saying of "having a lunch (dinner) engagement twice or three times a week." On the other hand, the response as saying of "tending to have many acquaintances compared to coworkers" was schematized in the close distance to the response as saying of very so.

  • The principal objective of this study was to determine the influence of physical evidence's performance on perception of value at family restaurants in Seoul. Frequency analysis, t-test, ANOVA, reliability analysis, factor analysis, multiregression analysis were employed to analyze the data. The physical evidence was divided into 3 factors. Factor 1, 'matters related to appearances and decoration'; and Factor 3, matters related to atmosphere' differed significantly with monthly pocket money. However, all factors differed significantly by partner. Additionally, all factors positively(+) influenced customer's perception of value. In particular, factor 1, 'matters related to appearances and decoration' was the most positive factor. As a result, physical evidence can be regarded as efficient marketing tactic by which the intangible factors of restaurant-business may be removed. Therefore, food-service companies should endeavor to manage physical evidence ideally as a means of reducing the negative characteristics of service toward customers and inducing customers perceptions of value at family restaurants.

  • The aim of this study is to investigate the usefulness of the parameter CPP (cepstral peak prominence) and LTAS (long term average spectrum) band energy for an analysis of breathy voice with vocal fold paralysis. Thirty-four female subjects who have vocal paralysis after thyroidectomy participated in this study. According to the perceptual judgements by three speech pathologists and one phonetic scholar, subjects were divided into two groups: breathy voice group (n = 21) and non-breathy voice group (n = 13). Maximum sustained phonation task was measured for acoustic analysis. CPP-related (i.e. mean F0, mean CPP, and mean CPPs) and LTAS-related (i.e. minimum, maximum, and mean) parameters were used. Independent samples t-test was conducted. Regarding CPP, there are significant differences in mean CPP and mean CPPs between groups. The values of mean CPP and CPPs in the non-breathy voice group are higher than those in the breathy voice group. The CPP could be regarded as the useful parameter for breathy voice analysis in the clinic. When it comes to LTAS, energy from 0 to 2 kHz are significantly different between groups. The minimum value of non-breathy group is lower than that of breathy group, whereas the maximum value of non-breathy group is higher. The frequency band below 2 kHz seems to be related to breathy voice.
