  • Purpose: Most proximal humeral fractures are minimally displaced and can be treated satisfactorily with a conservative method. But in many comminuted fractures, hemiarthroplasty is usually done as a primary treatment. The authors evaluated how much functional improvement was achieved after hemiarthroplasty and which factors influence on the final functional results. Materials and Methods: Eleven hemiarthroplasties were performed for three- and four-part fractures(including fracture-dislocation) between April 1992 and June 1999. There were eight women and three men, and the mean age was 65 years. According to Neer classification, six was three-part fracture and five was four-part fracture. Six patients were injured on their right shoulder and five on the left shoulder. Among the five four-part fractures, three had axillary nerve injury and among the six three-part fractures, only one patient had axillary nerve injury. The average follow-up period was 2.4 years(1 year-7 years) after operation. The functional results were evaluated with the UCLA scoring system(Modification for hemiarthroplasty). In addition to the overall results, we compared the results according to the classification of the fracture, the cause of injury, and whether the axillary nerve was injured. Results: At the last follow-up, average total UCLA score was 18.2. The mean score for pain was 7.0, mean muscle power and motion score was 5.5 and 5.7 respectively. The pain relief was more satisfactory than any other functional results. The average score for three-part fractures was 22, and the average for four-part fractures was 13.6. The average score for the patients fractured by vehicle accidents was 15.3, and 19.3 for the patients fractured by slip-down injury. In patients without axillary nerve injury, the average score was 20, and with axillary nerve injury, the score was 15. Conclusion: Shoulder hemiarthroplasty, for the treatment of proximal humeral fractures, cannot restore the shoulder function to normal, but can achieve the functional result to some degree, especially for the activity of daily living. And as for pain, we think that it is relatively effective measure. And we think that the severer the comminution, the more the chance of axillary nerve injury, and the poorer the functional results. In conclusion, the severity of initial injury seems to be the major prognostic factor.

  • Objectives: Whether there exists a distinct pathogenesis in subgroups of functional dyspepsia (FD), the classification of epigastric pain syndrome (EPS), and postprandial distress syndrome (PDS) remains controversial. We aimed to investigate the number of fungiform papillae (FP) in the subgroups of FD and its correlation with the severity of dyspepsia symptoms and spleen qi deficiency. Methods: Patients with FD were enrolled from August to November 2014. All patients were evaluated using a questionnaire and divided into 2 groups according to the Rome III criteria for FD. The severity of dyspepsia symptoms and spleen qi deficiency were separately assessed by Nepean Dyspepsia Index-Korean (NDI-K) version and Spleen qi deficiency questionnaire (SQDQ). The number of FP was measured on the anterior part of tongue, within an area of 9 mm 2, using a digital cam Results: The NDI-K score, SQDQ score, and number of FP in the EPS group were significantly greater than those in the PDS group. Also, the EPS group had more patients diagnosed with spleen qi deficiency. The number of FP showed a significant positive correlation with epigastric pain and burning. Furthermore, the number of FP was significantly associated with the score of some items in NDI-K and SQDQ, even though not with the total score. Conclusions: Thus, measurement of the number of FP could be a new evaluation indicator for allocation into FD subtypes and to investigate the severity of dyspepsia symptoms and spleen Qi deficiency reflecting visceral hypersensitivity.

  • Purpose: The purpose of this study was to describe the functional (mobility, self-care, social ability) and health-related quality of life in children with cerebral palsy (CP). Methods: A cross- sectional survey of 202 children with CP, mean age $5.91{\pm}1.57$ years, was carried out using the Gross Motor Function Classification System (GMFCS), Gross Motor Function Measure (GMFM), Pediatric Evaluation of Disability Inventory (PEDI), and Child Health Questionnaire (CHQ). Results: The functional assessment of children with CP showed that a more severe GMFCS level was associated with lower functional abilities (p<0.05). The health-related quality of life assessment showed that psychosocial well-being was less impaired than physical well-being. The internal consistency of the three instruments was satisfactory (cronbach's ${\alpha}$>0.80). The three different scales were correlated from moderate to strong (r=0.44 to 0.92). It was also found that mobility, tone distribution, and the parents' education level exerted a significant effect on the quality of life of children with CP (p<0.05). Conclusion: These findings suggest that children with CP have reduced function and quality of life and these are influenced by various factors. However, planning and application of various task-oriented functional interventions to childhood CP may be useful.

  • Purpose: The aim of this study was to investigate applicability of the GMFM-88 in planning intervention for CP children. Specifically, this study assessed functional improvement after a four-week GMFM-88 item-based training in CP children divided into three age groups (${\leq}24$ months, 25-48 months, and >48 months) and five levels of the gross motor function classification system (GMFCS). Methods: Subjects were 264 children with CP (mean age 32.90 months) recruited from one CP clinic. The GMFM-88 item-based training was planned for each child, after an interview with its caregiver. To investigate functional improvement after the intervention, minimum important difference (MID) and MID proportion for the change in scores of GMFM-88 were calculated. Results: The GMFM-88 scores increased after the interventions in all three age groups (p<0.05). In particular, children with CP aged ${\leq}24$ months and at the GMFCS level II showed greater functional improvement after training. Conclusion: This study found that the GMFM-88 item-based training would be used to plan activity-oriented intervention both in clinic and home in each CP child.

  • There is an emerging interest in brain functional connectivity (FC) based on functional Magnetic Resonance Imaging in Alzheimer's disease (AD) studies. The complex and high-dimensional structure of FC makes it challenging to explore the association between altered connectivity and AD susceptibility. We develop a pipeline to refine FC as proper covariates in a penalized logistic regression model and classify normal and AD susceptible groups. Three different quantification methods are proposed for FC refinement. One of the methods is dimension reduction based on common component analysis (CCA), which is employed to address the limitations of the other methods. We applied the proposed pipeline to the Alzheimer's Disease Neuroimaging Initiative (ADNI) data and deduced pathogenic FC biomarkers associated with AD susceptibility. The refined FC biomarkers were related to brain regions for cognition, stimuli processing, and sensorimotor skills. We also demonstrated that a model using CCA performed better than others in terms of classification performance and goodness-of-fit.

  • 법률상의 기록분류체계인 정부기능분류체계를 운용하는데 있어 여러 문제점이 확인되고 있는 상황에서 현재 정부출연연구기관 기록분류체계의 수준은 어떠한지를 확인하고 공공기관이자 연구기관인 정부출연연구기관이 어떤 분류체계로 정련되어가야 하는지 앞으로의 방향을 모색하고자 하였다. 이를 위해 23개 정부출연연구기관의 분류체계와 이를 뒷받침하는 관련 규정을 분석한 결과, 대다수 기관의 기록물관리규정이 기본적으로 공공기록물법, 더 나아가 공공기록물관리법 이전에 존재하던 규정에 근거하고 있다는 점을 확인하였다. 또한 공공기록물법을 반영한 기록생산시스템이 도입된 기관도 많지 않아 기록의 생산과 분류가 별개로 이뤄지고, 조직분류와 기능분류가 혼합된 분류체계는 보존기간 책정시 참고도구로서만 기능하는 경우도 많았다. 이런 상황을 극복하기 위해서는 제도, 체계, 시스템 측면에서의 개선전략이 필요하다. 국가차원에서의 법률 개정과 기관차원에서의 기록관리규정 제정이 이뤄져야 하며 연구기관의 핵심기능인 '연구'에 대해 특성화된 분류체계가 설계되고 이 분류체계는 반드시 기록의 생산등록 단계부터 적용되어야 할 것이다. 기록관리의무를 외면하고 생산기록을 제대로 관리하지 않는 것은 해당 연구 분야 기록의 가치를 스스로 부정하는 것이다. 빠른 기간 내에 정부출연연구기관의 기록관리가 제자리를 찾고, 실무적 이슈가 학계로 전달되어 더 나은 방향으로 발전할 수 있는 좋은 아이디어가 다시 실무영역으로 환류되길 기대한다.

  • Background: The presence of visuospatial impairment can make patients slow functional recovery and impede the rehabilitation process in TBI patients. Objective: The aim of this study is to investigate effects of prism adaptation treatment for functional outcomes in patients following traumatic brain injury. Methods: The subject received prism adaptation treatment for 2 weeks additionally during traditional rehabilitation for 4 weeks. The Patient has prism adaptation treatment while wearing wedge prisms that shift the external environment about $12^{\circ}$ leftward. The patient received 10 sessions, 15-20min each session. Outcome measures were visuospatial deficit(line bisection, latter cancellation), Visual and spatial perception(LOTCA-visual perception and spatial perception), motor function of upper extremity(FMA U/E; Fugl-Meyer motor assessment upper extremity, ARAT; Action research arm test), balance(BBS; Berg Balance Scale), mobility(FAC; Functional ambulation classification) and functional level(FIM; Functional independent measure). All Assessments took place on study entry and post-treatment assessments were performed at discharge from the hospital. Results: After prism adaptation, the visuospatial impairment scores improved as indicated in the line bisection(-15.2 to -6.02), latter cancellation(2 to 0) and LOTCA- spatial perception scores(7 to 9). The upper motor function improved as indicated in the scores of affected FMA U/E(21 to 40) and ARAT(4 to 22). Ambulation and balance improved as indicated in the BBS scores(25 to 38) and FAC scores(0 to 4). ADL function improved as indicated in the FIM total scores 54 to 70(motor 34 to 61, cognition 20 to 29). Conclusion: Prism adaptation did improve functional level such as motor functions and ADL abilities in TBI patient. Further research is recommended.
