In most leading companies, new product development is one of the most important corporate activities which affects the very existence of them. Therefore, CFT(cross-functional team) is frequently used to utilize knowledge and experiences of its members from various teams. To ensure the successful operation of CFT, various structural assistances, such as committee and Task Force Team, are made which will coordinate smooth interactions among members. Many researches show that the increase of interaction among team members affects the performance. This research is exploratory research intend to show the effects of relational characteristics such as group efficacy and participation on the perceived performance of new product development. This research examines the performance mechanism that lies in between CFT and its members by expanding the understandings on the relationship between interaction and performance in new product development CFT. Results show that the level of interaction affect group efficacy. and group efficacy affect participation. Finally, participation affect perceived performance. However. it shows that the level of interaction and group efficacy do not have direct effect on perceived performance.

Considering the complex structure and high volatility in the shipping market, it is important to investigate the connectedness amongst influencing factors. This study explores the dynamic relationship between supply-demand factors and shipping freight indices. We choose Capesize and Panamax in the bulk carrier market and use quarterly data of GDP, world fleet, BCI, and BPI from 1999 to 2021. Applying the wavelet analysis and wavelet Granger causality test, the simultaneous examination of co-movement and causality between two factors and the shipping market in both the time and frequency domains is achieved. We find that co-movement and causality vary across time and frequencies, thereby existing dynamic relationships between variables. Second, compared to multiple coherencies using demand and supply factors together, partial coherencies indicate noticeable causalities. It implies that analyzing demand and supply factors separately is essential. Finally, shipping freight indices show a high correlation with the demand factor in a good market and with the supply factor in a bad market. Generally, GDP positively leads shipping freights in the recovery phase while the world fleet negatively leads shipping freights in the downturn. The research is meaningful in that the rarely-applied wavelet analysis is adopted in the shipping market and that it gives a reasonable ground to explain the role of supply and/or demand factors in different phases of the market cycle.

Lately, developing systems fully interoperable with others is considered an essential element for successful projects, as not only do e-commerce becomes ubiquitous but also distributed systems' paradigm spreads. However, since definitions of interoperability vary by viewpoints, it is still difficult to have the same understanding and evaluation criteria on interoperability. For instance, various interoperability parties in military use different definitions of interoperability, and its T&E is not conducted according to the definition, but only to levels of information exchange. In this paper, we proposed a new definition of interoperability as followsm First of all, we collected existing and various interoperability definitions, extracting key components in each of them. Second, we statistically analyzed those components and applied the association rules discovery in data mining. We compared existing interoperability definitions to ours. From this research, we found associations among the components from various definitions applying market-basketanalysis, redefining interoperability. Key findings of this research can contribute to a unified viewpoint on the definition, level, and evaluation items of interoperability.

본 논문에서는 신호의 상호정보 추출에 의한 효율적인 군집화 방법을 제안하였다. 여기서 상호정보는 신호상호간의 상관관계를 나타내는 정보로 군집화를 위한 유사성을 나타내는 척도이다. 특히 적응적 분할을 이용하여 신호의 확률밀도를 계산함으로써 신호 상호간의 종속성을 좀 더 정확하고 빠르게 측정하였다. 제안된 방법을 500개 샘플을 가진 6개의 인위적인 신호군집화에 적용한 결과 정확한 분류성능이 있음을 확인하였다.

The representative elements of the SNS service are interactivity, information offering. This study analyzes empirical effects on the SNS service depending on the Relationship Commitment and shows the strategies to enlarge the use frequency and the On-line Word-of-Mouth. The conclusion of this study shows that the Interactivity has a higher positive effects on Affective Commitment than those on information offering and Information offering has stronger positive effects on calculative commitment than interactivity. Also, these effects enlarge the high use frequency more than the low use frequency. This study also shows that the information offering affect the On-line Word-of-Mouth more positively than the Interactivity. And this study shows that SNS service affects the positive effects on the relationship commitment rather than the On-line Word-of-Mouth. Based on the results, the practical implications are offered.

The purpose of this study was to examine the relationship of father's verbal control modes, children's self efficacy, social competence and interactive peer play. The subjects were pairs of 195 three, four and five year-old-children and their fathers. Data were analyzed with mean, standard deviation, and bivariate correlation. Results indicated that father's verbal control modes were significantly correlated with children's self efficacy, social competence and interactive peer play. Father's person-oriented control verbal mode was positively related to children's self-recognition, self-emotion, social competence, leadership and interactive peer play while imperative control verbal mode was negatively related to children's instability, interrupted play behavior, and disturbed play behavior.
