PURPOSE: The purpose of this study was to identify the mannerism phenomenon, which psychiatric nurses experience in hospitals. METHODS: Colaizzi’s phenomenological research methodology was used to illuminate the meaning and nature of the experience inherent for nurses when they provide nursing service. RESULTS: Analysis of the data collected through interaction with the participants showed five theme clusters, as follows: ‘Losing passion’, ‘Becoming impassive mien’, ‘Watching and folding up one's mind’, ‘Assimilating into the situation’ and ‘Being aware of change to one’s existing style.’ CONCLUSION: The results of this study provide a description of the phenomenon of mannerism as described by the participants, and allow for identification of the nature of the meaning of the mannerism experience. Accordingly, the study findings provide psychiatric nurses an opportunity to meditate on the nature of nursing in high-quality nursing service for patients with mental illnesses. Further, medical authorities need to provide the opportunity for nurses to apply nursing intervention therapy as part of nursing service and establish an institutional, administrative system to make it possible for nurses to provide service.

The purpose of this study was to investigate the changes of electromyogram activity of trunk and lower leg muscles during dynamic balance control in 20 healthy adult subjects when various experimental visual conditions were applied. Surface electromyography system was used for recording of any signals produced by muscles. Muscle activity was recorded from muscles, of which left and right sides of rectus abdominis, external obliques, longissimus thoracis, multifidus, vastus medialis, biceps femoris, gastrocnemius medialis, and tibialis anterior, and then normalized as percentage of maximum voluntary isometric contraction. All data obtained from experiment were analyzed using SPSS ver. 20.0, and two-way analysis of variance were used to determine statistical significance between two factors (3x2 factorial analysis, visual conditions vs. leg conditions). Statistical significance levels were set at alpha=0.05. There were significant different in biceps femoris and external obliques muscle's activities between right and left leg, showing more prominent reduction in left leg when blind vision condition was given. Significantly higher muscle activities were shown in both sides of multifidus (p<0.05), vastus medialis (p<0.001), tibialis anterior (p<0.001) and gastrocnemius medialis (p<0.001) with sighted vision and blanking vision compared to the condition of blind vision. These results confirmed that muscle activity is prominently stimulated by visual information provision, and this implies that visual input may be a major factor for maintaining of the body's balance control.

OBJECTIVE: Many people dealing with Parkinson’s disease (PD) turn to complementary and alternative medicine when searching for a cure or relief from symptoms. Acupuncture is widely used in the Korean PD population to alleviate symptoms and in hopes of curing the illness. However, acupuncture use for PD patients has only recently begun to be studied scientifically and is still considered an unproven treatment for PD. Therefore, there is an urgent need for acupuncture to be studied, validated and used for PD. Thus, our study’s aim is to examine how many acupuncture studies in PD are registered and reported in Korea. METHODS: The registries Clinicaltrials.gov and the Clinical Research Information Service (CRIS) and the search engine PubMed were searched to find relevant human clinical studies involving acupuncture therapy in PD patients. We examined the registration of trials, the posting and publication of results, and whether published articles were registered. RESULTS: In Clinicaltrials.gov, one completed trial was found with published results. In CRIS, one completed trial was found with published results. A total of 6 publications were found in our study: 2 articles were registered, but only 1 had the registered trial number listed in the article. CONCLUSION: Acupuncture is popular among the PD population in Korea regardless of its unproven safety and efficacy. Despite the pressing need for clinical trials, the number of studies listed in the registries was small, and only a few publications were registered. More effort and rigor are needed to validate the efficacy and safety of acupuncture for PD.

BACKGROUND AND PURPOSE: Research on stem cells (SC) is growing rapidly in neurology, but clinical applications of SC for neurological disorders remain to be proven effective and safe. Human clinical trials need to be registered in registries in order to reduce publication bias and selective reporting. METHODS: We searched three databases—clinicaltrials.gov, the Clinical Research Information System (CRIS), and PubMed—for neurologically relevant SC-based human trials and articles in Korea. The registration of trials, posting and publication of results, and registration of published SC articles were examined. RESULTS: There were 17 completed trials registered at clinicaltrials.gov and the CRIS website, with results articles having been published for 5 of them. Our study found 16 publications, of which 1 was a review article, 1 was a protocol article, and 8 contained registered trial information. CONCLUSIONS: Many registered SC trials related to neurological disorders are not reported, while many SC-related publications are not registered in a public registry. These results support the presence of biased reporting and publication bias in SC trials related to neurological disorders in Korea.

The central somatosensory conduction time(CCT) was measured by recording the cerebral and spinal evoked potentials following median nerve stimulation in 24 traumatic brain injury patients. The findings of evoked potential study correlated to the functional independence measure(FIM), mini mental status examination(MMSE) and Glasgow outcome scale(GOS). The CCT of head injured patients was prolonged compared to that of the controls. The CCT with stimulation of the affected side was significantly prolonged compared to that with non- affected side. Abnormal CCT was related to the poor functional status measured by FIM and GOS. There`s no significant difference between groups of absent evoked potential and prolonged CCT by FIM score. These results suggest that the CCT correlates with the functional status of head injured patients. Follow up studies are required to evaluate whether the CCT could be a valuable prognostic indicator or not.

OBJECTIVE: Given the considerable disagreement between the Peer Assessment Rating (PAR) index and the American Board of Orthodontics Cast-Radiograph Evaluation, we aimed to develop a novel assessment system-the Improvement and Completion of Outcome (ICO) index-to evaluate the outcome of orthodontic treatment. METHODS: Sixteen criteria from 4 major categories were established to represent the pretreatment malocclusion status, as well as the degree of improvement and level of completion of outcome during/after treatment: dental relationship (arch length discrepancy, irregularity, U1-SN, and IMPA); anteroposterior relationship (overjet, right and left molar position, ANB); vertical relationship (anterior overbite, anterior open-bite, lateral open-bite, SN-MP); and transverse relationship (dental midline discrepancy, chin point deviation, posterior cross-bite, occlusal plane cant). The score for each criterion was defined from 0 or −1 (worst) to 5 (ideal value or normal occlusion) in gradations of 1. The sum of the scores in each category indicates the area and extent of the problems. Improvement and completion percentages were estimated based on the pre- and post-treatment total scores and the maximum total score. If the completion percentage exceeded 80%, treatment outcome was considered successful. RESULTS: Two cases, Class I malocclusion and skeletal Class III malocclusion, are presented to represent the assessment procedure using the ICO index. The difference in the level of improvement and completion of treatment outcome can be clearly explained by using 2 percentage values. CONCLUSIONS: Thus, the ICO index enables the evaluation of the quality of orthodontic treatment objectively and consecutively throughout the entire treatment process.

Objective: To investigate the three-dimensional (3D) surgical accuracy between virtually planned and actual surgical movements (SM) of the maxilla in twojaw orthognathic surgery. Methods: The sample consisted of 15 skeletal Class III patients who underwent two-jaw orthognathic surgery performed by a single surgeon using a virtual surgical simulation (VSS) software. The 3D cone-beam computed tomography (CBCT) images were obtained before (T0) and after surgery (T1). After merging the dental cast image onto the T0 CBCT image, VSS was performed. SM were classified into midline correction (anterior and posterior), advancement, setback, anterior elongation, and impaction (total and posterior). The landmarks were the midpoint between the central incisors, the mesiobuccal cusp tip (MBCT) of both first molars, and the midpoint of the two MBCTs. The amount and direction of SM by VSS and actual surgery were measured using 3D coordinates of the landmarks. Discrepancies less than 1 mm between VSS and T1 landmarks indicated a precise outcome. The surgical achievement percentage (SAP, [amount of movement in actual surgery/ amount of movement in VSS] × 100) (%) and precision percentage (PP, [number of patients with precise outcomeumber of total patients] × 100) (%) were compared among SM types using Fisher’s exact and Kruskal–Wallis tests. Results: Overall mean discrepancy between VSS and actual surgery, SAP, and PP were 0.13 mm, 89.9%, and 68.3%, respectively. There was no significant difference in the SAP and PP values among the seven SM types (all p > 0.05). Conclusions VSS could be considered as an effective tool for increasing surgical accuracy.

Although influenza A (H1N1) virus leads to self-limiting illness, co-infection with bacteria may result in cases of severe respiratory failure due to inflammation and necrosis of intra-airway, as pseudomembranous tracheobronchitis. Pseudomembranous tracheobronchitis is usually developed in immunocompromised patients, but it can also occur in immunocompetent patients on a very rare basis. We report a case of pseudomembranous tracheobronchitis complicated by co-infection of inflenaza A and Staphylococcus aureus, causing acute respiratory failure in immunocompetent patients.
