인터넷 사용자는 호스트 접속을 위하여 DNS로부터 IP주소를 획득한다. 그러나 국내의 사용자는 익숙하지 않은 영문어순의 도메인을 사용하여야 한다. 기존 시스템의 어순은 한국어와는 반대이므로 인터넷 보편화에 장애가 되고 있다. 따라서 국내 사용자에게 적합한 한글 도메인 네임 시스템의 필요성이 높아지고 있다. 본 논문의 한글 도메인 시스템에서는 기존의 도메인 네임 시스템과 함께 운영하기 위하여, 영문으로의 변환 규칙과 한글 도메인 네임의 작성 규칙을 세웠다. 또 한글어순의 처리를 위하여 STROP을 설계하였다. STROP은 SLDF가 국문 SLD을 영문 SLD로 변환하며, 이를 NFDNG가 영문 어순으로 만들게 된다. 본 논문에서 제안한 한글 도메인 네임 시스템을 사용한다면 도메인 명의 함축된 의미를 사용자가 쉽게 파악할 수 있게 되고, 영문 전자로 인하여 발생하는 도메인 등록의 불만을 해소할 수 있으리라 기대된다. 그 결과 인터넷 보편화에 기여할 수 있을 것이다.

Purpose - This study analyzes effects of word of mouth intention of restaurant product via SNS on trust of products, purchase intention, and word of mouth intention targeting restaurant customers. Research design, data, and methodology - Targeting restaurant customers, 500 surveys were distributed in restaurants located in Seoul (where restaurants are clustered, such as Myeongdong, Dongdaemoon Station Shopping Center, and Sadangdong) between July 1st, 2016 and July 30th, 2016. Among those, 490 were collected, and 478 were used for analysis excluding those with no answer or insincere answers. Results - SNS word of mouth information characteristics had significant effects on trust of restaurant product in the order of vividness, neutrality, and timing. Trust on restaurant product has significant effect on perceived risks (-) and perceived benefits (+) by SNS. While perceived benefits of restaurant product on SNS has effect on purchase intention, perceived risks of restaurant product on SNS does not affect purchase intention. Perceived benefits of restaurant product on SNS has significant effect on word of mouth intention, whereas perceived risks of restaurant product on SNS does not have significant effect on word of mouth intention. Conclusions - As marketing through SNS can bring about a huge reduction effect in terms of marking cost, it can be utilized as an effective promotion by not only large restaurant corporations, but also small restaurants.

한글단어가 음운경로를 통해 처리되는지 아닌지를 알아보고 단어재인의 어느 단계에서 음운 정보의 영향을 주로 받는지 알아보기 위하여, 1음절 단어를 사용하고 철자를 지연시키는 실험올 하였다. 두 개의 초점조건은 옴가가 있는 철자를 지연시키거나 묵음을 지연시키는 조건이었다. 실험 1에서는 음운정보가 단어재인 초기에 영향을 미치는지 또는 후기 과정에서 영향을 미치는지 알아 보기 위하여, 점화자극을 l50ms와 250ms로 제시한 명명과제를 실시하였다, 그 결과 150ms로 점화자극 을 제시하였을 때에는 음가조건파 정화자극제시여부간의 유의한 상호작용이 나타나 묵음조건에서는 점화자극 제시에 따라 목표자극이 촉진된 반면 유음조건에서는 점화자극 제시에 따른 효과가 없었다. '반면, 250ms로 정화자극이 제시되었을 때에는 유의한 상호작용효파가 나타나지 않았다. 실험 2에서는 어휘 판단과제를 통해 실험 1의 결과가 일반화되는지를 살펴보았다 그 결과, 실험l과 마찬가지로 150ms로 정화자극을 제시하였을 때에는 음가조건과 점화자극제시여부 간의 유의한 상호작용이 나타났으나, 점화자극을 250ms로 제시한 경우에는 유의한 상호작용이 나타나지 않았다. 이상의 결과는 한글단어가 음운경로를 통해 처리되고, 주로 단어재인과정의 초기 단계에서 음운정보가 개입함을 시사한다.

This paper introduces a new linguistic-focused approach for sentiment analysis (SA) of Korean. In order to overcome shortcomings of previous works that focused mainly on statistical methods, we made effective use of various linguistic features reflecting the nature of Korean. These features include contextual shifters, modal affixes, and the morphological dependency of chunk structures. Moreover, in order to eschew possible confusion caused by ambiguous words and to improve the results of SA, we also proposed simple adjustment methods of word senses using KOLON ontology mapping information. Through experiments we contend that effective use of linguistic features and ontological information can improve the results of sentiment analysis of Korean.

This paper is a study on Korean word recognition and suggest the method that stabilizes the state-transition in the HMM by applying the `inertia' to the feature vector sequences. In order to reduce the quantized distortion considering probability distribution of input vectors, we used SOFM, an unsupervised learning method, as a vector quantizer, By applying inertia to the feature vector sequences, the overlapping of probability distributions for the response path of each word on the self organizing feature map can be reduced and the state-transition in the Hmm can be Stabilized. In order to evaluate the performance of the method, we carried out experiments for 50 DDD area names. The results showed that applying inertia to the feature vector sequence improved the recognition rate by 7.4% and can make more HMMs available without reducing the recognition rate for the SOFM having the fixed number of neuron.

We developed a test of English silent word reading, following work by Mather, Hammill, Allen and Roberts (2004) and Bell, McCallum, Krik, Fuller, and McCane-Bowling (2007), in order to tap Hong Kong Chinese children's reading of English as a foreign language. We created one subtest of individual word reading and another of word reading contextualized within sentences; together, these tests require no more than 10 minutes for administration. In Study 1, we administered the entire test to 552 second grade Hong Kong Chinese children between the ages of 70 and 121 months old, from five different primary schools. The association between the subtests of English silent word reading and contextual reading was positively correlated (.78). In Study 2, 77 Hong Kong Chinese second graders were tested on our newly developed English silent word reading test, together with non-verbal IQ, an English word reading and a Chinese character recognition test (both read aloud). With age and non-verbal IQ statistically controlled, there was a significant correlation between English silent word reading and the more standard English word reading, read aloud, (.78); the association between English silent word reading and Chinese character recognition was also positively correlated (.49). This newly created test is a quick and reliable measure, suitable for both educators and researchers to use to identify poor readers who learn English as a foreign or second language.

The purpose of this study was to examine the effects of banking service quality on consumer satisfaction and positive word-of-mouth. A total of 330 bank consumers were investigated between Sept. 11 and Oct. 11, 2006. After sorting through the data, the responses of 299 consumer ( > 24 yrs old) were used for analysis. SERVPERF, the performance component of the Service Quality scale (SERVQUAL), was used to measure the four dimensions of reliability, responsiveness/empathy, assurance, and tangibles. Responses were partitioned by age and gender. The major findings were as follows; The effect of service quality by SERVPERF on consumer satisfaction and positive word-of-mouth did not differ according to gender. However, positive recommendation in males was directy related to the technical quality evaluate. In females, higher the functional quality evaluate was directly related to higher positive word-of-mouth recommendation. The effect of service quality by SERVPERF on consumer satisfaction was not revealed differently according to age. However, with respect to respondents under the age of 45, tangibles and assurance had a positive relationship with word-of-mouth recommendation. Furthermore, the higher the functional quality evaluate, the higher the level of positive word-of-mouth. Responsiveness/empathy was the most significant factor on positive word-of-mouth recommendation in respondents over the age of 45. In this age group, the higher the technical quality evaluate, the higher the level of positive word-of-mouth recommendation. These results have implications for banking service managers, particularly in improving service quality to increase consumer satisfaction and positive word-of-mouth. Future research is needed to replicate this study using more broad and representative samples in order to test the generalization of these findings.

Three experiments were conducted to determine the exact locus of the frequency effect in speech production. In Experiment 1. a picture naming task was used to replicate whether the word frequency effect is due to the processes involved in lexical access or not. The robust word frequency effect of 31ms was obtained. The question to be addressed in Experiment 2 is whether the word frequency effect is originated from the level where a lemma is selected. To the end, using a picture-word interference task, the significance of interactions between the effects of target frequency, distractor frequency and semantic relatedness were tested. Interaction between the distractor frequency and semantic relatedness variables was significant. And interaction between the target and distractor frequency variables showed a significant tendency. In addition, the results of Experiment 2 suggest that the mechanism underlying the word frequency effect is encoded as different resting activation level of lemmas. Experiment 3 explored whether the word frequency effect is attributed to the lexeme level where phonological information of words is represented or not. A methodological logic applied to Experiment 3 was the same as to Experiment 2. Any interaction was not significant. In conclusion, the present study obtained the evidence supporting two assumptions: (a) the locus of the word frequency effect exists in the processes involved in lemma selection, (b) the mechanism for the word frequency effect is encoded as different resting activation level of lemmas. In order to explain the word frequency effect obtained in this study, the core assumptions of current production models need to be modified.
