Mangrove plants serve as a sink of heavy metals and contain phenolic compounds at a high level. Therefore, with mangrove plants, recent studies to develop phytoremediation and natural antioxidants have been conducted in the commercial and academic fields. In the present study, six mangroves in Weno Island of Micronesia were investigated for their phylogenetic relationship and antioxidant activities. First, to determine the phylogenetic relationship among them, rbcL (large subunit of ribulose-bisphosphate carboxylase), one of the chloroplast genes, was used as a molecular marker. According to the data, Xylocarpus, Sonneratia and Rhizophora showed close similarity but not Excoecaria. The levels of phenolic compounds in the bark were abundant in R. apiculata and X. granatum, accounting for 1.10 mM/mg, while R. stylosa and S. alba contained the low amounts, representing 0.73 mM/mg and 0.72 mM/mg, respectively (p<0.05). In addition, bark extracts from R. apiculata, X. granatum, X. moluccensis, and E. agallocha had high antioxidant activities through the DPPH radical scavenging activity and ABTS analysis, whereas S. alba showed the lowest activities. These results suggest that the bark of R. apiculata can be used as a good source for the development of natural antioxidants.

This study was conducted to derive core and detailed competencies of dental hygienists to be utilized as educational targets to be reached by graduation as well as basic data that can be reflected in the development and improvement of dental hygiene curricula. This study analyzed publication reports from the Korean Dental Hygienists Association, the International Federation of Dental Hygienists, the Commission on Dental Accreditation, and the American Dental Education Association. Based on the academic classification system for dental hygiene studies, the components of core and detailed competencies of dental hygiene school at the time of graduation were extracted and developed through expert panel discussions. This study defined competencies at the graduation level of dental hygiene school and derived eight core competencies and their 52 detailed competencies to serve as educational objectives from four areas: professionalism, communication, clinical practice, and community and health promotion. In the future, it will be necessary to conduct self-assessments of competencies based on those developed in this study, at time of the graduation from dental hygiene school, as well as to continuously develop competency-based curricula according to entry level, knowledge level, and graduation level. Thus, it is urgently necessary to develop a system that can evaluate the competencies of dental hygienists after graduation and put this system into practical use.

The incidence of extremity amputation is estimated at about 200,000 cases annually. Over 25% of patients suffer from terminal neuroma or phantom limb pain (TNPLP), resulting in pain, inability to wear a prosthetic device, and lost work. Once TNPLP develops, there is no definitive cure. Therefore, there has been an emerging focus on TNPLP prevention. We examined the current literature on TNPLP prevention in patients undergoing extremity amputation. A literature review was performed using Ovid Medline, Cochrane Collaboration Library, and Google Scholar to identify all original studies that addressed surgical prophylaxis against TNPLP. The search was conducted using both Medical Subject Headings and free-text using the terms "phantom limb pain," "amputation neuroma," and "surgical prevention of amputation neuroma." Fifteen studies met the inclusion criteria, including six prospective trials, two comprehensive literature reviews, four retrospective chart reviews, and three case series/technique reviews. Five techniques were identified, and each was incorporated into a targetbased classification system. A small but growing body of literature exists regarding the surgical prevention of TNPLP. Targeted muscle reinnervation (TMR), a form of physiologic target reassignment, has the greatest momentum in the academic surgical community, with multiple recent prospective studies demonstrating superior prevention of TNPLP. Neurorrhaphy and transposition with implantation are supported by less robust evidence, but merit future study as alternatives to TMR.

Although lithium metal batteries have a high energy density, experimental skills capable of solving lots of problems induced by dendrite such as short circuit, low coulomb efficiency, capacity loss, and cycle performance are still only in academic research stage. In this paper, research cases for dendrite growth inhibition on lithium metal electrode were classified into four types: flexible SEI (solid electrolyte interface) layer responding to volume expansion of lithium metal electrode, SEI supporting layer to inhibit dendrite growth physically, SHES (self-healing electrostatic shield) mechanism to adjust lithium growth by leading uniform diffusion of Li⁺ ions, and finally micro-patterning to induce uniform deposition of lithium. We hope to advance the practical use of lithium metal electrode by analyzing pros and cons of this classification.

Objectives : This study was founded to identify the differences of stress responses, according to Sasang Constitutions (the Taeyangin, Taeumin, Soyangin and Soumin) of highly stressed oriental medicine college students. Methods : The subjects were 76 students who majored in oriental medicine. We processed 'University students Stress Scale', and 'Medical Stress Scale'. We selected 30 students who stressed higher than average. We then processed 'QSCC II (Questionnare for the Sasang Constitution Classification II)' and 'Scale for the Stress Response'. Collected data was analyzed with the SPSS 19.0 for windows statistical program. Results : The university students stress score of oriental medicine students was 1.97 that was higher than the other college students. The medical stress score was 2.77, which was similar with other medical college students. The symptoms of stress score was 2.53, which was higher than the others. Particularly, the depressive syndrome and rage syndrome were highly ranked. The frequently appearing symptoms of each type of Sasang Constitutions (the Taeyangin, Taeumin, Soyangin and Soumin) showed as follows. The Soyangin's symptoms of stress showed in order of Anxiety, Depression, and Emotional irritability. The Soumin's symptoms of stress showed in order of Depression, Emotional irritability, and cognitive disorganization. The Taeumin's symptoms of stress showed in order of Anxiety, Depression, and Emotional irritability. However, there was were no significant differences among the results of each constitution. Conclusions : The results show that oriental medicine students have as much stress as other medical college students and there was tendency of showing different patterns of stress response, according to Sasang Constitution, but it's not significantly different.

Adverse drug events (ADEs) are the most common type of adverse events in medical practice. Hospital admissions related to ADEs cost high and should be monitored to prevent them. While concerns about the ADEs are increasing, the frequency and characteristics of admissions related to ADEs have not been reported in Korea. The objective of the study was to assess the rate of hospital admission related to ADEs and their characteristics through ADE signal-based retrospective reviews of medical records. As results, a total of 1,420 patients had ADE signals suggesting potential ADEs from 3,494 patients who discharged from an academic medical center over one month period. Six pharmacists independently assessed the presence of ADEs after the review of patients' medical records. Among the 3,494 discharges, 62 admissions (1.8%) were found to be realted to ADEs. Of admissions with ADEs, 83.9% were moderate (category F by the NCC MERP classification), 37.2% were preventable, and 85.5% were type A reaction. The most frequent suspected drugs causing ADEs were antineoplastics (48.9%), and the most frequent ADE signal detecting hospital admissions related to ADEs was white blood cell count (24.2%). Hospital admissions related to ADEs were found through screening the ADE signals. The ADE signal-based retrospective review could be a practical approach for identifying hospital admissions related to ADEs.
