Previous studies have suggested that individuals need to invest in the accumulation of career competencies. To demonstrate how to acquire career competencies, a model consisting of the knowing why, knowing how, and knowing whom competencies was actively discussed in the previous studies. This study seeks to identify the relationships among these competencies based on three ways of knowing, and their effects on perceived work performance. Furthermore, this study tried to identify the importance of each of these competencies in predicting perceived individual performance in the business workplace environment. The findings showed that the knowing why, knowing how, and knowing whom competencies all have a statistically significant positive influence on perceived individual work performance. Also, the study results showed the relative importance of the three competencies for perceived work performance. Specifically, the study results showed that the effects of the knowing why and knowing whom competencies are greater than the effect of the knowing how competency. The theoretical and practical implications of the study results were provided, including empirical evidence of the validity of the career capital model, the appropriateness of the career competency model based on the three ways of knowing, and assignment of resources for the acquisition of career competencies.

The study aims to define the career competency of HRD practitioners based on an intelligent career framework. This intelligent career framework has been described as having been achieved by the accumulation of career capital through the three ways of knowing, including knowing why, knowing how, and knowing with whom. The data were collected from the interviews with 15 HRD practitioners. Semi-structured interviews were used to collect data from the HRD practitioners. For the orientation about the interview, the researcher explained the importance of gathering data about the personal experiences of the respondents on their work and career. After that explanation, the researcher asked several questions based on the pre-structured interview guide. The data collected were qualitatively analyzed on the basis of the intelligent career framework. Based on the analysis of the interviews, the subcategories of each way of knowing competency were identified. For the knowing why, identity, credibility, and career clarity were identified. The subcategories of knowing how are remaining updates, hard skills, and soft skills, while the subcategories of knowing with whom are personal networking and professional networking. The interdependency among the three career competencies was found. The findings provide theoretical implications of applying an intelligent career framework.

Sustainable development is a key issue in the 21st Century and ecotourism is an alternative area of sustainable development. Ecotourism marketing is also a part of societal marketing which emphasizes social contributions. This study investigated the factors which affected ecotourist satisfaction and behavioral intentions. The sample for this study was composed of 212 ecotourists who visited the Upo area. This is one of the most well-known educational ecotourism sites in Korea and it has been registered at the Ramsar Convention for the conservation of wetlands since 1998. This study demonstrated that expectation factors did not significantly influence satisfaction. Second, the performance factors of physical attributes, eco-interpretation, eco-experience, and usability did significantly influence satisfaction. Third, the expectation factor of accessibility was significantly related to disconfirmation. Fourth, all performance factors significantly influenced disconfirmation. Fifth, it was found that disconfirmation significantly influenced satisfaction. Finally, satisfaction significantly influenced the intention to revisit and recommend the site to others. Managerial implications and future studies are discussed.

It has been believed that supplementation of human diets with soybean products markedly reduces human cancer mortality rates. Specifically the black colored soybean has been considered as having a medicinal effect since ancient times in Korea. Six genotypes of black colored soybean and a normal variety were investigated for their biological effect. While the isoflavone content of black colored soybean was higher than the normal soybean, saponin content of the seeds was not different among varieties. In the case of antioxidant activity, black colored soybean showed over 3 times increase in the active effect than the control variety. When feeding soybean extract, a general change of alcohol resolving effect, such as alcohol dehydrogenase activity, was observed in the blood and liver of rats.
