Maintaining active users who repeatedly share high-quality knowledge is critical for the success of online Q&A sites. This study suggests two paths that lead to active users' continuous knowledge sharing: 1) elaborated decision process, represented by continuance intention, and 2) automated cognitive process, represented by past behavior. The direct and moderating effects of continuance intention and past behavior were verified by analyzing subjective intention data and objective behavior data of 333 active users of Naver Knowledge-iN. Using Cox proportional hazards regression and negative binomial regression, the influences of continuance intention and past behavior on two types of continuous knowledge sharing were examined. The results showed that only past behavior was significantly influential on knowledge sharing continuance and as to the frequency of knowledge sharing, both continuance intention and past behavior's influences were significant. It was also confirmed that past behavior negatively moderates continuance intention's effect on the frequency of knowledge sharing. In order to maintain active users' continuous knowledge sharing, it is important to habituate knowledge sharing through repetitive knowledge sharing behavior. And in order to increase the frequency of knowledge sharing, in addition to the habituation, appropriate benefits that can increase the continuance intention should be provided.

많은 경제 시계열 자료 중에서 주가는 국내외 경제상황은 물론 정부정책 등 시장 외적인 영향에 가장 민감하게 반응한다. 하지만, 지금까지의 주가예측에 있어서는 이러한 외부의 영향, 즉 개입(Intervention)이 발생했을 때 주가의 변동에 능동적으로 대처하는 모형이 부재하였다. 실제로 이러한 개입사실을 예측모형에 반영하지 않는다면, 주가예측 있어 그 예측력을 따진다는 것은 무의미하다고 판단된다. 따라서, 개입시점을 발견하고, 이 개입효과를 측정하여 이를 모형에 반영한다면 좋은 예측결과를 얻을 수 있을 것이다. 이 연구에서는 이상점 탐지절차를 이용하여 개입 시점을 발견하고 개입의 효과가 개입시점에만 영향을 주는 모형과 효과가 일정기간 지속되는 모형으로 두 개의 개입시계열모형을 구축하고, 이러한 두 모형의 예측성과와 인공신경망모형을 이용한 예측성과를 비교하였다. 초단기예측(개입 직후 예측)에 있어서 개입의 효과가 지속되는 경우에는 개입시계열이 인공신경망보다 좋을 결과 를 나타내긴 했지만 그 차이는 크지 않았으며, 개입의 효과가 시점에만 영향을 준 경우에는 인공신경망의 결과가 더 우수한 것으로 나타났다. 단기예측(개입 후 20 일후의 예측)에 있어서는 개입 효과의 지속여부에 상관없이 인공신경망이 개입시계열모형보다 우수한 것으로 나타났다.

지역개발과 지역의 지속가능한 발전전략의 수립을 위해 지역의 환경적, 사회적, 경제적 특성을 통합한 지속가능발전 모델을 구축하는 것은 매우 중요하다. 본 논문은 지속가능발전 전략의 모색과 관련정책의 파급효과를 측정하기 위하여 이러한 통합모델의 개발과 적용을 목적으로 한다. 이러한 목적에 따라 높은 환경질을 유지하고 대나무와 같은 생태자원을 육성함으로써 생태관광과 대나무신산업 등의 새로운 지역개발 정책을 수행하는 전라남도 담양군을 대상으로 지속가능발전 체계동태모형을 구축한다. 담양군 사례분석의 결과는 죽림육성 정책과 대나무신산업과 같은 지역특화산업에 대한 기술개발 및 각종 재원의 병행이 인구유입과 지역경제의 활성화에 매우 효과적임을 제시하고 있다. 결론적으로 본 논문에서는 지역의 지속가능성에 관한 시스템적 사고를 통해 지역개발에 있어서 지역의 환경적 특성을 살린 생태자원의 육성과 적절한 산업정책을 병행하는 생태발전 전략이 지역의 지속가능발전에 있어서 매우 중요한 수단이 될 수 있음을 제시하고 있다.

This study examines empirically whether appropriateness of training program, learning organization, and demographic factors enhance the effectiveness of training program for HRD in small and medium companies. The major findings are as follows: The appropriateness of training program, learning organization, and demographic factors of employee has a strong positive effect on the effectiveness of training program for human resource development and intent to participate in the training program in small and medium enterprise. The learning organization has a strong positive effect on the effectiveness of training program for human resource development and intent to participate in the training program in small and medium enterprise. Also effectiveness of training program for human resource development and intent to participate in the training program in small and medium enterprise is different according to demographic factors such as job type(blue collar job, office job, sales job), rank of job position, and the length of service in organization. The significant results of this study is that appropriate design of training program to make employees understand the purpose of education and trying to activate the learning organization can increase the effectiveness of traing program in small and medium enterprise.

The present study is aimed to investigate antecedents(person-job fit, human capital investment) and outcome variable(subjective career success) of continuous-related career learning, and to demonstrate mediating effects of continuous-related career learning. The data which was applied to analysis was collected from 241 office workers who have worked for automobile company in Ulsan and public companies in Jeju and applied temporal separation of measurement as an alternative for common method bias. The results are as follows. First, person-job fit, human capital investment affected to career-related continuous learning positively. Second, the impacts of career-related continuous learning to subjective career success was positively significant. Third, the mediating effects by career-related continuous learning demonstrated statistically significant in the links between antecedents-outcome variables as partial mediation. Implications of this study contribute to expand research area of continuous-related career learning with regard to job and organizational variables, and to facilitate of research interests on subjective career success. In addition, the mechanism of career advance was empirically proved by continuous-related career learning.

다중음성 합성시스템은 단일 화자의 음성을 입력받아 다양한 음색의 다중음성으로 합성을 해주는 음성합성 시스템이다. 기존의 다중음성 합성시스템의 출력인 다중 합성음은 피치만 변경된 음성으로 원 음성과 동일한 지속시간을 갖게 된다. 따라서 피치 변경된 음성간의 구분이 어렵게 되며 이러한 사항을 개선하고자 본 논문에서는 피치와 지속시간 변경에 의한 다중음성 합성시스템에서 관한 연구를 하였다. 본 논문에서는 시간 영역에서의 지속시간 변경법인 PSOLA방식을 적용하여 피치 변경된 음성의 지속시간을 변경하였다. 지속시간 변경을 적용한 다중음성 합성시스템을 이용하면 한 사람의 음원 목소리로 여러 사람이 응원하는 효과음을 낼 수 있는 합성기로 사용할 수 있고 영화의 효과음, 핸드폰의 음성 메시지 서비스 등에서 용이하게 사용될 것으로 예상하고 있다.

We analyzed the relationship among customer value, satisfaction and continuous use intention of tourism social commerce in this study. And also we observed the moderating effects of regulatory focus on the relationship between customer value and satisfaction. As the results, we found partially positive relationship between customer value and satisfaction and positive relationship between satisfaction and continuous use intention of tourism social commerce. The regulatory focus partially moderated the relationship between customer value and satisfaction. Finally we emphasize the importance of customer value, enhancing promotion focus and weakening prevention focus for continuous use intention of tourism social commerce.

The purpose of this study was to investigate the effect of perceived risk on continuous usage intention of Internet primary banks and to verify moderating effects of acceptance factors affecting customers' acceptance of Internet primary banks on the relationship between perceived risk and continuous usage intention. The study aims to find ways to cope with perceived risk and strategic measures of intention in order to increase the intention to continuous usage intention of Internet primary banks. For the analysis, interaction effect were conducted among a total of 457 surveys. As a results, First, perceived risks, acceptance factors and continuous usage intention of the customers of Internet primary banks were significantly correlated. Second, the types of perceived risks which have a significant effect on continued usage intention of Internet primary banks were found to be perceived financial and functional risks. Third, respect to moderating effects of moderator variables, usefulness was found to have a significant moderating effect on the relationship between perceived security risk and continuous usage intention. In addition, ease of use was shown to have a significant moderating effect on the relationship between each type of perceived risks and continuous usage intention. This study attempted to explore and seek strategies to reduce perceived risks and strategic plans for acceptance factors to increase continuous usage intention of Internet primary banks.

환경적 요인으로 인하여 측정간격이 지속시간이 변할 수 있는 지의 l여부를 알아보기 위해 실험을 행하였다. 실험에서의 측정간격은 어절단위이며 이러한 실험을 통해서 소위 구-길이 효과의 한 츠면도 파악해 볼 수 있다. 측정간격 양쪽의 어절에서 체계적인 음절증가를 유도한 뒤 나타날 수 있는 측정간격의 지속시간에서의 변화율을 측정하였다. 결과는 엄격한 의미에서 체계적으로 기술될 수 있을 만한 단음화효과는 나타나지 않았다. 어느 정도의 융통성을 둔다면 순행단음화 효과의 부분적인 출현은 인정할 만하다. 문장의 중간에 위치한 어절과 양쪽 환경 각각을 짝을 지워 상관관계를 따져본 결과 양의 상관이 더 많이 나타났다. 결과적으로 실험에서의 측정간격은 지속시간에 관한 한 문장 내에서 독립적인 활동을 하는 단위로 생각할 수 있다.
