일반적으로 고음질 음성합성을 하기 위해서는 합성음의 지속 시간을 변경하여 줌으로써 운율을 조절하는 기법이 필요하다 이에 먼저 고음질용 음성부호화법을 선정하여야 하고 정확한 피치와 피치시점검출을 통해서 음원분류가 되어야한다. 본 논문에서는 제안한 자동 피치시점 검출을 적용해서 운율조절에 필요한 지속시간 조절 법을 제안하고자 한다. 제안한 방법은 시간영역에서 직접 처리하기 때문에 피치동기분석이 용이하고 다른 영역으로의 변환과정이 불필요하다. 결과적으로 파형부호화법을 적용하고 제안한 자동 피치서점 검출에 의한 지속시간 조절법을 적용하였을 때 비교적 우수한 결과를 얻을 수 있었다.

In this paper, an adaptive multimedia synchronization scheme for VOD (Video On Demand) services in internet environments is proposed. This scheme considers the characteristics of MPEG (Moving Picture Expert Group) system stream. Consequently, the intra-synchronization is handled at the pack layer, and the inter-synchronization is handled at the packet layer. The proposed scheme can cope adaptively with variation of packet loss, jitter and client's playback capacity. If there are variations of the packet loss or client's playback capacity, the server will change the transmission rate by selective picture skip. The client can then adjust and control the playback time according to the variation of the network jitter. Our experimental results show that the proposed scheme can quickly adapt to the network condition, and can guarantee a better quality of service than the other existing schemes.

The purpose of this study is to investigate the determinants of employees' knowledge contribution to 'Easysam', the Defense Knowledge Sharing System(DKSS), and provide managers and system designers with implications for enhancing the usage of the DKSS. Although the system seems to be helpful for employees to conduct their tasks by sharing and applying knowledge from the system, use of the system is confined to restricted employees and little empirical, systematic research has been done for this area. Therefore, using the motivation opportunity ability theory of behavior, this study hypothesizes that motivation factors(enjoy helping, reward confirmation), opportunity factor(system accessibility), and ability factor(self-rated expertise, tenure in the field) increase the level of employees' knowledge contribution to the DKSS. This research also includes hypotheses which address the effect of system use voluntariness, a moderator, on the relationship between predictors described above and knowledge provision. Survey results show that the effect of enjoy helping, reward confirmation, self-rated expertise and system accessibility is significant on employees knowledge provision. However, tenure in the field has no influence on its contribution of knowledge to the system. Theoretical and practical implications are provided.

Although several studies have made and policies have formulated for an increase in women's participation in economic activities, the participation rate of women in economic activities in Korea is only 50% and much lower than in other advanced countries. This study aims to analyze the factors that affect women's continuance intention in economic activities including their motivation for economic activities, women's perception of work, and government support recognition. We empirically analyze and examine such factors and the moderating effects of family support. The survey was conducted on women nationwide to be distributed evenly among various age groups, ranging from those in their 20s to those in their 50s. The results of the empirical analysis based on the data collected on a total of 406 people were as follows. First, the motivation for economic activities including economic and self-realization motivation, women's perception of work, and government support was seen as having a significantly positive effect on women's Continuance Intention in Economic Activities. Second, the impact of women's work perception on their continuance intention in economic activities varied depending on the level of family support, and its moderating effect was confirmed. But there was no moderating effect of family support between economic and self-realization motivation, government support recognition, and the women's continuance intention for economic activities To increase women's continuance intention for economic activities, both support for work-family compatibility policies and institutional support should be provided. Government support will also be needed in order to enable women with abundant experience to participate in economic activities.

Psychological properties of learners have influence on learning behaviors in various ways. The purpose of this study was to examine how the goal orientation of learners affected the learning time distribution method. Regulatory focus and theories of intelligence were measured and manipulated in order to differentiate participants' goal-oriented state. Two variables are known to be key variables influencing learner's goal orientation, inducing the approach-avoidance strategy and mastery-performance oriented attitude. In the experiment, the control focus was divided into two groups based on the inclination test score (regulatory Focus Questionnaire, RFQ), and TOI(theory of intelligence) was temporally induced through manipulation to confirm the interaction between the two variables. Participants were able to determine the order of learning freely by learning a set of Spanish-Korean word pairs and then selecting the items they would like to re-learn. Word pairs consisted of difficult or easy items, and learners could learn the same word many times if they wanted to. In the results, promotion-incremental group showed allocating difficult word-pairs in early time.

Children play a crucial role in the lives of parents, but research on the parent-child relationship has focused mainly on its impact on parents' social relationships and happiness. This study explored how parenting motives affect the association between parents' relationship satisfaction with children and subjective well-being. Previous studies have suggested that the psychological benefits of achievement or positive experiences in specific life domains are dependent on the perceived importance of such domains. Thus, we hypothesized that a satisfying relationship with children can strongly predict the subjective well-being of parents with elevated parenting motives. The study included Korean (Study 1) and American (Study 2) participants. Results of both studies demonstrated a pronounced positive correlation between parents' relationship satisfaction with children and subjective well-being in individuals with high levels of parenting motives. This moderating effect persisted even after controlling for relevant covariates (e.g., gender, age, and Big 5 personality traits). Notably, this effect was particularly evident in subfactors of subjective well-being, which is negative affect.

Many embedded real-time systems have adopted processors supported with dynamic voltage scaling(DVS) recently. Power is one of the important metrics for optimization in the design and operation of embedded real-time systems. We can save considerable energy by using slowdown of processor supported with DVS. In this paper, we propose heuristic algorithms to calculate task slowdown factors for an efficient energy consumption in embedded real-time systems with task synchronization. The previous algorithm has a following constraint : given the tasks are ordered in a nondecreasing order of their relative deadline, the task slowdown factors computed are in a nonincreasing order. In this paper, we relax the constraint and propose heuristic algorithms which have the same time complexity that previous algorithm has and can save more energy. Experimental results show that the proposed algorithms are energy efficient.

Entrepreneurship provides working opportunities to not only an entrepreneur himself but also many other people on the way its process. Boosting entrepreneurship, therefore, seems the most effective way for activating one's economy as well as creating jobs. This study examines factors that influence on entrepreneurial intention of Korean and Korean-Chinese's who will eventually be the potential entrepreneurs. This model tests various theoretical research hypotheses relating to individual psychological characteristics, and entrepreneurial motivation and entrepreneurial intention. Valid 247 questionnaires have been collected within about one month of 2013. Statistical processing of the data collected from this survey to take advantage of the statistical package SPSS 18.0 program through a process of data coding in the following ways: by frequency analysis, factor analysis, regression analysis. The result of hypothesis testing are as follows. The result of analysis shows that risk-taking propensity and desire for self-achievement is not a significant factor to entrepreneurial intention in both countries. But entrepreneurial self-efficiency and entrepreneurial motivation positively influence entrepreneurial intention both of the Korean and Korean-Chinese. At the last, the study examines moderate effect, that is, whether social support influences on entrepreneurial intention as a moderate variable. it is confirmed that the social support does play a positive role to entrepreneurial intention. Beside, discussion is made on the implications of the study for academicians and practitioners, the limitations of the study, and some directions for future studies.
