Two experiments were conducted to examine the role of Kulja and morpheme in processing two-syllable Sino-Korean words. In Experiment 1, the effects of morphemic frequency were not significant at the initial and final positions of a word while Kulja frequency and Kulja-morpheme correspondence at both positions in a word had a significant impact on the processing of nonwords. Lexical decision times were longer for nonwords with high frequency Kulja and for nonwords with ambiguous Kulja-morpheme correspondence whose Kulja can go with many different morphemes. In Experiment 2 Kulja-morpheme correspondence was examined for words as well as nonwords. Lexical decisions were slower for stimuli with ambiguous Kulja-morpheme correspondence. The effect was more stable for nonwords, which replicated the result of Experiment 1. In sum, the results of this study suggest that words with ambiguous Kulja-morpheme correspondence activate many different morphemes and competition among these morphemic candidates slows down the lexical selection process. Kulja frequency, Kulja neighborhood, morphemic frequency, morphological neighborhood, and Kulja-morpheme correspondence in Korean word recognition were also discussed.

The study of the awareness on DM, the degree of satisfaction, and intention of word-of-mouth has found that when the confidence factor is stressed, intention of word-of-mouth is seen to rise, and when the perception factor is placed emphasis on, intention of word-of-mouth is also seen to be on the rise. The 790 questionnaires collected were analyzed by frequency, factor analysis, confidence degree, and regression analysis. This means that the higher the degree of satisfaction by means of the recognition, attention, trust of DM advertisement, the relationship reenforcement of DM advertisement and transmission of information is, the higher intention of word-of-mouth is. Beauty art business is characteristic of visits being connected with sales. The awareness has an effect on the degree satisfaction, and it affects intention of word-of-mouth. Therefore, it is thought that Beauty art business requires systematic, analytic and unique DM advertisement.

This study investigates the effects of ChatGPT's quality characteristics (service and information) on purchase intention and word of mouth intention. We distributed questionnaires among domestic men and women aged in their 20s and 30s who had experience of using ChatGPT. A total of 222 responses were subjected to frequency analysis, factor analysis, correlation analysis, and multiple linear regression analysis using the IBM SPSS statistical program version 26. The major findings were as follows: (1) The factors of service quality were categorized as Tangibility, Reliability, Empathy, and Assurance, while the factors of information quality were categorized as Recency, Accuracy, and Usefulness. (2) Among the service quality factors of ChatGPT, two factors (Reliability and Empathy) significantly impacted purchase intention, and three factors (Tangibility, Reliability, and Empathy) significantly affected word of mouth intention. (3) Among ChatGPT's information quality factors, two factors (Usefulness and Recency) had a significant effect on purchase intention, and two factors (Usefulness and Accuracy) exerted a significant influence on word of mouth intention. (4) Purchase intention had a significant effect on word of mouth intention.

The age of acquisition effect is the phenomenon in which the words acquired early in life are processed better than the words acquired later in life. Age of acquisition and word frequency are critical factors in lexical processing. In this study we examined the age of acquisition effects in Hangul word recognition. In Experiment 1, we examined the AoA effects in word naming and lexical decision tasks. The results showed that there was an interaction between task and age of acquisition. The AoA effects appeared only in the lexical decision task. In Experiment 2, we examined the relationship between age of acquisition and word frequency in the lexical decision task. The results showed that the two variables were significant. The early-acquired words were processed better than the words acquired later, and the words with high frequency were processed better than the words with low frequency. However, there was no interaction between the two variables. In Experiment 3, we examined how phonological changes in Hangul words influence the AoA effects. The results show that the AoA effects were similar whether phonological changes occur or not. Our results are discussed in terms of several theoretical hypotheses.

The present study investigated the mental representation and processing of an ambiguous word in the bimodal processing system by manipulating the lexical ambiguity of a visually or auditorily presented word. Homonyms (e.g., '물었다') with more than two meanings and control words (e.g., '고통을') with a single meaning were used in the experiments. The lemma frequency of words was manipulated while the relative frequency of multiple meanings of each homonym was balanced. In both experiments using the lexical decision task, a robust frequency effect and a critical interaction of word type by frequency were found. In Experiment 1, spoken homonyms yielded faster latencies relative to control words (i.e., ambiguity advantage) in the low frequency condition, while ambiguity disadvantage was found in the high frequency condition. A similar interactive pattern was found in visually presented homonyms in the subsequent Experiment 2. Taken together, the first key finding is that interdependent lexico-semantic processing can be found both in the visual and auditory processing system, which in turn suggests that semantic processing is not modality dependent, but rather takes place on the basis of general lexical knowledge. The second is that multiple semantic candidates provide facilitative feedback only when the lemma frequency of the word is relatively low.

The purpose of this study is to ascertain the effect of the reputation of ski resorts on multidimensional trust, customer satisfaction and spread by word-of-mouth. To attain this goal, 400 adult male and female subjects using 3 Ski Resorts located in Gangwon-do in Korea in 2013 were selected. For this, convenient sampling was used. The data was processed with the 382 final available samples excluding the 18 inappropriate questionnaires through frequency-, exploratory factor-, reliability-, correlation-, and simple/multiple regression-analyses by using the PASW 18.0. The result is as follows. First, the reputation of the ski resorts was found to have a positive effect regarding the trust of the resorts and their employees. Second, trust in ski resorts and their employees was found to have a positive effect on customer satisfaction. Third, trust in ski resorts and their employees was found to have a positive effect on the spread of word-of-mouth about the resorts. Fourth, customer satisfaction was found to have a positive effect on the diffusion by word-of-mouth.

Previous studies of syllable frequency effects have proposed that inhibitory effects due to high first syllable frequency were the products of competitions between activated lexical candidates within a lexical level. However, these studies have primarily used lexical decision tasks to examine the nature of syllable frequency effects. This study investigates whether a syllable frequency effect can arise in semantic categorization tasks and whether phonologically or orthographically defined syllables interact with semantically related variables such as morphological family size. If the syllable frequency effect was created by activations and competitions on a lexical level, it is highly possible that the effect was related to semantic categorization tasks. To test this hypothesis, we conducted two experiments. In Experiment 1, morphological family size and phonological syllable frequency were factorially manipulated. In Experiment 2, morphological family size and orthographic syllable frequency were factorially manipulated. The results demonstrate that morphemes have no relationship with phonological syllables but do with orthographic syllables. This suggests that phonological syllables and orthographic syllables have different roles in the syllable frequency effect on visual word recognition process.

In this study, we suggest Korean nonlinear fitting formula (KNFF) to maximize speech intelligibility for digital hearing aids based on NAL-NL1 (NAL-nonlinear, version 1). KNFF was derived from the same procedure which is used for deriving NAL-NL1. KNFF consider the long-term average speech spectrum of Korean instead of English because the frequency characteristic of Korean is different from that of English. New insertion gains of KNFF were derived using the SII (speech intelligibility index) program provided by ANSI. In addition, the insertion gains were modified to maximize the intelligibility of high frequency words. To verify effect of the new fitting gain, we performed speech discrimination test (SDT) and preference test using the hearing loss simulator from NOISH. In the SDT, a word set as test material consists of 50 1-syllable word generally used in hearing clinic. As a result of the test, in case of moderate hearing loss with severe loss on high frequency, the SDT scores of KNFF was more improved about 3.2% than NAL-NLl and about 6% in case of the sever hearing loss. Finally we have obtained the result that it was the effective way to increase gain of mid-high frequency bands and to decrease gain of low frequency bands in order to maximize speech intelligibility of Korean.
