Aim of the study: This study aims to analyze and record orally transmitted knowledge of medicinal plants from the indigenous people living in the southern mountainous region of Korea. This article is the first study of its kind. Materials and methods: Data was collected through the participatory rural appraisal (PRA) method involving interviews, informal meetings, open and group discussions, and overt observations with semi-structured questionnaires. Results: The investigation reveals that the indigenous people have used 217 species of medicinal plants distributed in 177 genera belonging to 77 families with 691 different uses. The representative families were Asteraceae (13.5%) followed by Fabaceae (8.2%), Araliaceae (6.1%), Rosaceae (5.8%), Cucurbitaceae (4.1%), Poaceae (3.0%), Liliaceae (2.7%), and Apiaceae (2.6%). On the whole, 21 kinds of plant-parts were used and prepared in 26 various ways by the people for medicinal purposes. The informant consensus factor (ICF) values in the ailment categories were veterinary ailments (0.88), pains (0.84), cuts and wounds (0.77), and respiratory system disorders (0.76). In terms of fidelity levels, 41 plant species showed 100% of fidelities. Conclusion: In recent years, the Korean society has been a heavy loss of traditional practices due to a rapid decrease of the senior population. This pressing circumstance raises the level of urgency for the preservation of indigenous knowledge from extinction. A priority should be given first for collecting and recording indigenous knowledge from the natives inhabiting the national parks and environmental preservation areas. © 2011 Elsevier Ireland Ltd.

Problem-based learning (PBL) has been identified as an approach that improves the training of nurses by teaching them how to apply theory to clinical practice and by developing their problem-solving skills, which could be used to overcome environmental constraints within clinical practice. A consensus is emerging that there is a need for systematic reviews and meta-analyses regarding a range of selected topics in nursing education. The purpose of this study was to conduct a meta-analysis of the available literature in order to synthesize the effects of PBL in nursing education. Using a number of databases, we identified studies related to the effectiveness of PBL in nursing. An analysis was conducted on a range of outcome variables, including overall effect sizes and effects of evidence and evaluation levels, learning environment, and study characteristics. We found that the effect of PBL in nursing education is 0.70 standard deviations (medium-to-large effect size). We also found that PBL has positive effects on the outcome domains of satisfaction with training, clinical education, and skill course. These results may act as a guide for nurse educators with regard to the conditions under which PBL is more effective than traditional learning strategies. © 2012 Springer Science+Business Media Dordrecht.

A goal of this study is to develop a Composite Knowledge Manipulation Tool (CKMT). Some of traditional medical activities are rely heavily on the oral transfer of knowledge, with the risk of losing important knowledge. Moreover, the activities differ according to the regions, traditions, experts' experiences, etc. Therefore, it is necessary to develop an integrated and consistent knowledge manipulation tool. By using the tool, it will be possible to extract the tacit knowledge consistently, transform different types of knowledge into a composite knowledge base (KB), integrate disseminated and complex knowledge, and complement the lack of knowledge. For the reason above, I have developed the CKMT called as K-Expert and it has four advanced functionalities as follows. Firstly, it can extract/import logical rules from data mining (DM) with the minimum of effort. I expect that the function can complement the oral transfer of traditional knowledge. Secondly, it transforms the various types of logical rules into database (DB) tables after the syntax checking and/or transformation. In this situation, knowledge managers can refine, evaluate, and manage the huge-sized composite KB consistently with the support of the DB management systems (DBMS). Thirdly, it visualizes the transformed knowledge in the shape of decision tree (DT). With the function, the knowledge workers can evaluate the completeness of the KB and complement the lack of knowledge. Finally, it gives SQL-based backward chaining function to the knowledge users. It could reduce the inference time effectively since it is based on SQL query and searching not the sentence-by-sentence translation used in the traditional inference systems. The function will give the young researchers and their fellows in the field of knowledge management (KM) and expert systems (ES) more opportunities to follow up and validate their knowledge. Finally, I expect that the approach can present the advantages of mitigating knowledge loss and the burdens of knowledge transformation and complementation. © 2014 Elsevier Ltd.

Using a nonequilibrium Green's function method combined with density functional theory, we have calculated the quantum conductance of a recently synthesized μ-borolyl triple-decker sandwich complex, in which Ru and Co ions are sandwiched between three five-membered rings. The current-voltage characteristics of the complex when connected to Au (111) wire exhibit a strong nonlinear and asymmetric behavior at applied bias, in which multiple negative differential resistance (NDR) effects are observed. Our detailed analysis shows that the origin of the effect is quite diverse: this diversity can be attributed to the existence of a narrow bulk or surface electrode density of states and the alignment and misalignment of d-states of two metal ions. The substitution effect has been also investigated by replacing hydrogen atoms on the central ring with electronegative chlorine atoms. © 2010 American Chemical Society.

In this technical brief, we develop an algorithm to determine the explicit solution of the constrained min-max model predictive control problem. For a discrete-time linear system with bounded additive uncertain disturbance, the control law is determined to be piecewise affine from a quadratic cost function and the state space is partitioned into corresponding polyhedral cones. By moving the on-line implementation to an off-line explicit evaluation, the computational burden is decreased and the applicability of min-max optimization is broadened. The results of this approach are shown via computer simulations. © 2011 IEEE.
