Recent years have seen steadily increasing concerns about human exposure to heavy metals through seafood consumption. In Korea, the diverse dietary patterns of different bivalve shellfish necessitate tissue-specific evaluation of heavy metal contents for risk assessment. We analyzed the heavy metal contents of various tissues in scallops (Patinopecten yessoensis) and pen shells (Atrina pectinate). In both species, we found higher levels of cadmium (Cd) in the mantle than in the adductive muscle, while there was no significant difference between the two tissue types in total mercury (THg) and lead (Pb) (P<0.05). Levels of THg and Pb were acceptable by Korean standards. However, the level of Cd in pen shell mantle tissue exceeded the standard by 40%. The rate of heavy metal exposure from consumption of these species was shown to be 0.003-0.010% of the provisional tolerable weekly intake of THg and 0.312-0.600% of the provisional tolerable monthly intake (PTWI) of Cd as recommended by the Joint FAO/WHO Expert Committee on Food Additives. These findings on the tissue-specific heavy metal contents of these species will be useful in assessing the health risks of Korean dietary habits.

Physicians, in order to study the causes of cancer, detect cancer earlier, prevent or determine the effectiveness of treatment, and specify the reasons for the treatment ineffectiveness, need to access accurate, comprehensive, and timely cancer data. The cancer care environment has become more complex because of the need for coordination and communication among health care professionals with different skills in a variety of roles and the existence of large amounts of data with various formats. The goals of health care systems in such a complex environment are correct health data management, providing appropriate information needs of users to enhance the integrity and quality of health care, timely access to accurate information and reducing medical errors. These roles in new systems with use of agents efficiently perform well. Because of the potential capability of agent systems to solve complex and dynamic health problems, health care system, in order to gain full advantage of E- health, steps must be taken to make use of this technology. Multi-agent systems have effective roles in health service quality improvement especially in telemedicine, emergency situations and management of chronic diseases such as cancer. In the design and implementation of agent based systems, planning items such as information confidentiality and privacy, architecture, communication standards, ethical and legal aspects, identification opportunities and barriers should be considered. It should be noted that usage of agent systems only with a technical view is associated with many problems such as lack of user acceptance. The aim of this commentary is to survey applications, opportunities and barriers of this new artificial intelligence tool for cancer care information as an approach to improve cancer care management.

This paper investigates how strategy formulation and implementation processes used by the University of Cape Coast (UCC) in building its digital collections compare with the Andrew's strategic formulation and implementation theoretical framework. Theory-testing case study methodology was used. The data collection instruments were the key informant interview technique and document reviews. During the formulation phase, two aspects (resources and aspirations of senior management) were emergent. During the implementation phase, five aspects (achieving results, processes and behaviour, standards, motivation, personal) were emergent. All other elements of building the UCC digital collections were planned during both the formulation and implementation phases. Although the emphasis on students and learning is laudable and apt, there seems to be lack of focus on research support beyond digital collection building, despite the fact that research excellence is one of the UCC's key priorities. Opportunities exist for improving feedback mechanisms between the users, digital library staff and the university management; and inclusion of social media tools in the digital library project. Since only the experience of a single institution of higher learning is considered, it cannot be definitively stated that strategy formulation and implementation will be similar in every institutional context. However, the results provide a basis for academic digital libraries to draw lessons from this case. In African public universities, there is little earlier research on strategy formulation and implementation in digital library management. Strategy formulation and implementation is a critical issue for higher education academic libraries especially in developing countries like Ghana, due to limited financial resources and the rapid change in the information environment during the last several decades.
