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.

UML is a semantically rich language, but it is difficult to ensure consistency of the diagrams you have written. Therefore, in this paper, we propose cross checking rules to improve consistency between UML diagrams, especially between UML static diagram and dynamic diagram. We use metamodels in order to more clearly reflect interactions of UML elements in the checking rules and use OCL(Object Constraint Language) to accurately represent the checking rules. By comparing with the well-formedness rules of UML specification, we focus on consistency of UML diagrams. And we derive metamodels of static diagram and dynamic diagram, analysis the relationships of UML diagrams and finally, we test the usability of derived rules through a case study.

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.

In the current information environment, metadata interoperability has become the predominant way of organizing and managing resources. However, current approaches to metadata interoperability focus on the superficial mapping between labels of metadata elements without considering semantics of each element. This research applied facet analysis to address these difficulties in achieving metadata interoperability. By categorizing metadata elements according to these semantic and functional similarities, this research identified different types of facets: basic, conceptual, and relational. Through these different facets, a faceted framework was constructed to mediate semantic, syntactical, and structural differences across heterogeneous metadata standards.

The study examined moderating role of thinking style about causality in the relationship between the perceived brand globalness(PBG) and the brand evaluation. Thinking style about causality is divided into interactionism and dispositionism. Individualism culture shows a tendency of thinking style about causality to dispositionism, and collectivist cultures shows a tendency for interactionism. We conducted a survey on Korean college students who represent collectivist cultures and foreign students from countries of individualistic culture and analyzed data through structural equation modeling. Analysis result showed that the higher the respondents perceived PBG, the higher they perceived brand quality, brand quality, and brand price. However, it showed that PBG has greater positive effects on perceived brand quality and perceived brand reputation among Korean students than students from individualistic cultures. On the other hand, the effects of PBG on perceived brand price did not show any significant difference between Korean students and students from individualist cultures. Thus, we can conclude that thinking style about causality plays a moderating role in the relationship between PBG and perceived brand quality and brand reputation, while it does not do so between PBG and perceived brand price.

The purpose of this study is to investigate the effect of vendor perceived equity on the performance of retailer-vendor relationship. The empirical study of 386 vendors identified the following results. First, retailers' ethical management positively influenced on vendors' perception on procedural justice and interactional equity, whereas boundary personnel's ethical management positively influenced only on interactional equity. Second, distributive equity was positively influenced by procedural equity and interactional equity. Third, the performance of retailer-vendor relationship was directly affected by distributive equity and interactional equity, whereas procedural equity indirectly influenced on the relationship via distributive equity.

This study aims to investigate the relationship between service recovery justice, residual emotions, and customer behavior. It empirically verifies that low justice in service recovery affects residual emotions and, in turn, has an impact on customers' negative behaviors. Furthermore, this research distinguishes customer-brand relationship quality into emotional relationship quality and cognitive relationship quality and seeks to validate that the type of relationship quality may influence the extent to which the justice of recovery processes affects residual emotions. Data was collected through surveys, and hypotheses were tested using structural equation modeling. The research findings indicate that among the dimensions of service recovery justice, procedural justice and interactional justice significantly influence residual emotions. Moreover, residual emotions have a significant impact on both the intention to revisit and the intention to engage in negative word-of-mouth. In addition, the impact of distributive justice and procedural justice on residual emotions was found to be higher for cognitive relationship quality than emotional relationship quality, and the impact of interactional justice on residual emotions was found to be higher for emotional relationship quality than cognitive relationship quality.

This study examines the ways in which Confucianism developed in connection with other thoughts. Mythology especially had an great impact on the formation of Confucian thoughts. This study focuses on the concept of sage and examines how Confucianism and mythological thoughts influenced on formation and reformation of the concepts. In ancient religion, sages as a hierophantic figure, mediates human beings and gods, delivering the gods' messages to the human and the human's wishes to the gods. The fused role of shaman and ruler began to separate. A new type of leader without political power, but with a religious role with a moral authority is the Confucian concept of sage. A sage in Confucianism is an ideal person like Confucius, Mencius, and Xunzi, an ordinary person can attain with effort. Anyone can become a sage in Confucianism. The early Confucian sage was more like a hyper-human with unaccessible authority in mythology. Later, a sage in Confucianism began to be described as a model figure that any human being can become. The aspect of shamans and diviners (wushi 巫師) did not disappear, but merged into a kingly power and transformed into a sage-king with moral authority. The new images are reflected in Confucian ideology of statehood or its religiosity. This study has explored the ways in which Confucianism and mythological thoughts interacted and influenced to each other through a concept of sage as an ideal personhood.
