This study aimed to examine the effect of ad attributes on engagement, the mediating effect of engagement on the relationship between ad attributes and advertising effectiveness (attitudes toward ads, continuous intention to search, and e-WOM intention), and the differences in advertising effectiveness at different levels (low vs. high) of curiosity toward fashion video ads in the online context. For this purpose, a total of 408 responses were collected from consumers who were aged 20-40 years and had viewed fashion video ads via PC/mobile channels in the preceding six months. The results showed that three advertising attributes, namely informativeness, entertainment, and personalization, were significant predictors of engagement. Additionally, engagement had a significant mediating effect on the relationship between entertainment and ad effectiveness. Moreover, both informativeness and entertainment had a significant direct effect on the behavioral intention to search and engage in e-WOM. At the high-curiosity level, engagement had a significant influence on ad attitudes and e-WOM intention. In contrast, at the low-curiosity level, entertainment had a significant influence on e-WOM intention and continuous intention to search. These findings are meaningful in that they extend the advertising attitude model to fashion video ads in the online context.

This paper describes on the Korean continuous speech recognition system for flight reservation. It adopts a frame-synchronous One-Pass DP search algorithm driven by syntactic constraints of context free grammar(CFG). For recognition, 48 phoneme-like units(PLU) were defined and used as basic units for acoustic modeling of Korean. This modeling was conducted using a HMM technique, where each model has 4-states 3-continuous output probability distributions and 3-discrete-duration distributions. Language modeling by CFG was also applied to the task domain of flight reservation, which consisted of 346 words and 422 rewriting rules. In the tests, the sentence recognition rate of 62.6% was obtained after speaker adaptation.

This research is to examine the structural relationships between transformational/transactional leadership, empowerment, relationship quality, and organizational commitment in Chinese restaurant context. In order to empirically investigate the proposed model, the data were collected from 188 respondents randomly selected from among the managers who work in 188 Chinese restaurants in Seoul and Kyonggi-do, which registered in Korean Food Central Association, korean foodservice management Association, Menupan.com We choose to limit our investigation to luxury Chinese restaurants where the average check is above 12,000 won. The survey was executed during two-week period in the autumn of 2004. The findings and discussion are as follows: First, intellectual stimulus behavior of transformational leadership had a positive effect on empowerment. Second, contingent reward leadership had a positive effect on empowerment. Third, empowerment had a positive effect on affective organizational commitment. Fourth, empower had a negative effect on continuous organizational commitment. Fifth, intellectural stimulus behavior of transformation leadership had a positive effect on affective organizational commitment indirectly and had a negative effect on continuous organizational commitment indirectly through mediating role of empowerment. Finally, contingent reward leadership had a positive effect on affective organizational commitment indirectly and had a negative effect on continuous organizational commitment indirectly through mediating role of empowerment. At the end of this paper, managerial implications, discussions, and limitations and future research directions are presented.

The increasing popularity of the Internet has led to the emergence of online service delivered by websites. Given large investments in these websites, it is important to retain existing customers in online service contexts. In order to understand how website information and system attributes may influence perceived usefulness of using the websites, customer satisfaction, and ultimate continuous usage behaviors, we develop a model to integrate user satisfaction with technology acceptance. Furthermore, this integration is sharpened through the synthesis with research on continuous usage of online service based on customer satisfaction. We then test the model using a sample of 236 respondents who have used one of the most popular Internet blog and community service in South Korea within the last three months. The analysis results suggest that website information and system attributes play key roles in forming continuous intention of the service and perceived playfulness serves as an important moderator toward customer satisfaction. Our model is more likely to help link website design and invesment decisions to the strategy for retaining existing customers in the context of online service.

본 논문에서는 연속분포 HMM에 이산 지속시간제어와 회귀계수를 파라메터로 추가한 이산 지속시간제어 연속분포 HMM 모델을 이용하여 한국어 연속음성 인식 시스템을 구성하였다. 또한 25 문장의 로보트 제어명령문을 유한상태 오토마타에 의해 구문제어를 실시한 One Pass DP법으로 인식 실험을 실시하였다. 4연 숫자음에 대한 인식 실험에서 이산 지속시간 제어와 회귀 계수를 포함한 경우 평균 $93.8\%$의 인식율을, 포함하지 않은 경우 $80.7\%$의 인식율을 얻었다. 로보트 제어 명령문의 인식에서는 구문제어를 실시하지 않은 경우 평균 $90.9\%$, 유한 상태 오토마타에 의한 구문제어를 이용한 경우 평균 $98.4\%$로 $7.5\%$의 인식율이 향상되었다.

이 연구의 목적은 저소득층이 경험하는 행복의 맥락을 이해하고자 하는 것이다. 이러한 목적을 달성하기 위해서, 이 연구에서는 질적 연구방법을 활용하였으며, 귀납적 접근을 통해 자료를 분석하였다. 구체적으로, 먼저 저소득층이 경험하는 행복의 맥락을 사례별로 살펴보았다. 개별 연구참여자들이 부여한 행복 점수와 그 의미, 주관적 경험들과 다양한 영역들로 구성된 현상을 분석하고, 그러한 행복과 경험, 현상으로 구성된 맥락 구조를 그려보았다. 사례들을 개별적으로, 그리고 연속적으로 분석하고 검토하고 연결하는 과정을 통해, 결과적으로 전체 사례들을 통합할 수 있는 맥락 구조가 구성되었다. 분석 결과, 연구참여자인 저소득층들이 인식하는 행복의 수준은 객관적인 상태보다는 주관적인 경험과 직접 관련되는 것으로 나타났다. 또한 이들의 주관적인 경험은 마음 안에서 작용하는 매우 복합적인 경험 요소들로 구성되어 있으며, 개인의 가치관에 의해 어떠한 경험요소들이 더 중요하게 평가되는가에 따라서 행복의 수준이 달라지는 것으로 나타났다. 이러한 연구결과에 근거하여, 저소득층의 행복수준을 향상시키기 위해 고려해야 할 정책과 실천 지침들을 제언하였다.

A Phonetic Tied-Mixture (PTM) model has been proposed as a way of efficient decoding in large vocabulary continuous speech recognition systems (LVCSR). It has been reported that PTM model shows better performance in decoding than triphones by sharing a set of mixture components among states of the same topological location[5]. In this paper we propose a Phonetic Tied-Mixture Syllable (PTMS) model which extends PTM technique up to syllables. The proposed PTMS model shows 13% enhancement in decoding speed than PTM. In spite of difference in context dependent modeling (PTM : cross-word context dependent modeling, PTMS : word-internal left-phone dependent modeling), the proposed model shows just less than 1% degradation in word accuracy than PTM with the same beam width. With a different beam width, it shows better word accuracy than in PTM at the same or higher speed.

For large vocabulary speech recognition using HMMs, context-dependent subword units have been often employed. However, when context-dependent phone models are used, they result in a system which has too may parameters to train. The problem of too many parameters and too little training data is absolutely crucial in the design of a statistical speech recognizer. Furthermore, when building large vocabulary speech recognition systems, unseen triphone problem is unavoidable. In this paper, we propose the modified phonetic decision tree algorithm for the automatic prediction of unseen triphones which has advantages solving these problems through following two experiments in Japanese contexts. The baseline experimental results show that the modified tree based clustering algorithm is effective for clustering and reducing the number of states without any degradation in performance. The task experimental results show that our proposed algorithm also has the advantage of providing a automatic prediction of unseen triphones.
