This study examines the relative usefulness of the TPB and Extended TPB with the addition of the "Battery" variable to participants in marine sports experiences. The characteristics of behavioral theories (attitude, subjective norms, perceived behavioral control, and revisit intention) were compared. A total of 420 questionnaires were distributed and surveyed using the convenience sampling method to the general public who participated in the marine sports experience in S city in 2019. Finally, 385 copies of valid samples were extracted, except for the questionnaire. The following analyzes were performed using SPSS 21.0 and AMOS 21.0. Frequency analysis, confirmatory factor analysis, concept reliability, AVE value, Cronbach's α correlation analysis, hierarchical regression analysis, and independent sample t-test were performed. First, in the TPB, three predictors were found to have a positive effect on revisit intention. Attitudes, subjective norms, and prior knowledge, except for behavioral control, were found to have a positive effect. Second, the explanatory power to explain the return intention was 51.8% (3.3% more than plan behavior theory, p = .000). It can be seen that when prior knowledge is added as a new variable, it is an important factor in explaining intention to return. Third, prior knowledge variables were classified into high and low groups to compare the characteristics of the extended planning behavior theory. The results of the analysis showed that the group with higher prior knowledge had a higher mean value for the constituent variables of the extended planning behavior theory.

Preannouncing a new product to its target audiences has been more and more prevalent in a wealth of industries, particularly industries that attach great importance to the speed of entry. Grounded in market signaling theory, the current research advances a theoretical model that takes full cognizance of the relation between preannounced information about an upcoming product and individual customers' behavioral intentions as well as significant moderating effects of prior product knowledge and new product innovativeness. In response, a web-based survey is conducted for data collection and the structural equation model is utilized for data analysis. Results of this study demonstrate that preannounced new product information attributes (i.e., quantity, clarity) may positively influence consumers' attitudes, in turn, lead to a favorable purchase intention. Moreover, the moderating effects of product knowledge and product innovativeness are also confirmed. Specifically, product knowledge moderates the quantity-attitude relation positively and moderates the clarity-attitude relation negatively, whereas product innovativeness does opposite. Both implications and limitations are also described.

사람의 언어를 이해하는 자연언어처리 시스템을 개발하기 위해서는 의미처리를 위한 지식 베이스(knowledge base)가 필요하다. 지금까지 사람이 가진 지식 베이스를 컴퓨터에 도입하려는 많은 노력을 기울이고 있고 그 결과물로 온톨로지(ontology)와 시소러스(thesaurus)가 만들어지고 있다. 외국에서는 지식 베이스의 중요성을 알고 많은 연구를 수행하고 있으며 그 대표적인 사례들에는 Roget's Thesaurus, WordNet, EDR 개념사전, CYC, Euro WordNet 등이 있다. 이 중에서 가장 대표적이며 많은 활용을 보이는 것이 Princeton 대학의 WordNet이다. WordNet은 인간의 어휘지식에 대한 심리 언어학적인 연구의 결과물로써 심리학자와 언어학자들에 의해 10여 년 동안 구축되고 있는 영어에 대한 어휘데이터베이스이다. 본 논문에서는 WordNet을 기반으로 명사에 대해서 영한사전과 국어사전을 이용하여 구축한 한국어 워드넷을 소개하구 구축시 고려한 기본지침을 소개하도록 하겠다.

This study offered lexical knowledge acquisition model of unsupervised learning method in order to overcome limitation of lexical knowledge hand building manual of supervised learning method for research of natural language processing. The offered model obtains the lexical knowledge from the lexical entry which was given by inputting through the process of vectorization, clustering, lexical knowledge acquisition automatically. In the process of obtaining the lexical knowledge acquisition of model, some parts of lexical knowledge dictionary which changes in the number of lexical knowledge and characteristics of lexical knowledge appeared by parameter changes were shown. The experimental results show that is possibility of automatic building of Machine-readable dictionary, because observed to the number of lexical class information cluster collected constant. also building of lexical ditionary including left-morphosyntactic information and right-morphosyntactic information is reflected korean characteristic.

This study analyzed empirically difference of purchase intention about price raising of luxury brand according to consumer characteristics such as consumption value, prior knowledge. and perceived risk. Fist, groups according to consumption value showed obvious differences. Group of pursuing uniqueness and ostentation value and group of pursuing quality and pleasure value showed positive purchase intention but group of pursuing social recognition value showed negative purchase intention. Second, groups according to perceived risk. didn't show difference and groups according to prior knowledge showed obvious difference. group of high prior knowledge showed positive purchase intention but group of low prior knowledge showed negative purchase intention. Third, analyzed result about interaction effect of consumer characteristics, Classified group of pursuing uniqueness and ostentation value, expressing high prior knowledge and Classified group of pursuing quality and pleasure value, expressing high perceived risk only showed positive purchase intention, The results of this study present implication to domestic companies aiming luxury brand that performing differently strategy of product and price according to target characteristics is more effective way in differentiating oneself from existing luxury brands and expanding market.

The purpose of this research is to examine the impacts of persuasion knowledge and pre-attitude on responses to a persuasive entertainment education program. Persuasion knowledge model was adopted as the theoretical frame and information about the sensational identity of entertainment program was used to activate audience's persuasion knowledge(i.e. resistance). Pre-attitude was measured by the degree of concern about the persuasion topic. The experiment was designed by persuasion knowledge(2) ${\times}$ pre-attitude(2) and participants were randomly assigned in one of the conditions and rated their attitude for the persuasion topic. The implicit measure for attitude was included in addition to the explicit measures in order to reveal unconscious attitudinal changes. The results showed that the allegedly effective entertainment-education can confront the resistance of the audience in some contexts. A significant interaction of knowledge ${\times}$ pre-attitude was found in the result of the implicit attitude. The individuals with high concern about the persuasion topic, compared to those with low concern, were more influenced by the entertainment program and also persuasion knowledge. The interaction was not significant on the explicit attitude, which may present the usefulness of the implicit measure in entertainment-education research.

The purpose of this study was to analyze the college students' acceptance of PatentNOW, which was developed for effective proceeding of patent application education program. Results of this research as follow. First, perceived ease of use positively influenced perceived usefulness. Second, perceived usefulness and perceived ease of use positively influenced attitude toward using and attitude toward using also positively influenced behavioral intention to use. Third, the level of prior knowledge about the patent system and experience of patent application possessed by the users of PatentNOW had a negative effect on the relationship between perceived ease of use and attitude toward using. These results suggested that the teaching method of utilizing PatentNOW should be differentiated according to the level of prior knowledge of the students in order to improve the quality of patent application education.
