Purpose: The objective of this study was a virtual reality-based balance training program effective for improvement in physical function, examined the balance ability and fall efficacy of elderly women with experienced falls, intending to examine the program's usefulness as an exercise program to prevent the recurrence of a fall. Methods: The participants were 30 elderly women aged 65 or older who met the conditions. The participants were randomly assigned to either a balance training group (BT) or a virtual reality-based balance training group (VT) and received the training three times per week, 30 minutes per day, for six weeks. To measure static balance, the Tetrax Portable Multiple System (Tetrax Ltd, Israel) were used. To measure dynamic balance, the Berg Balance Scale (BBS) and functional reach test (FRT) was used, and regarding fall efficacy, the Korean Fall Efficacy Scale (K-FES) was used. Results: Tetrax significantly improved after the intervention in both the BT group and the VT group (p<0.05). The comparison between the two groups was not significantly. BBS and FRT result significantly improved after the intervention in both the BT and VT groups (p<0.001), while K-FES was significantly ameliorated in the VT group only (p<.05). Comparing the groups, there were more significant changes in the BBS (p<0.05) and FRT (p<0.01) result of the VT group than the BT group. Conclusion: A virtual reality-based balance training program is considered to be usable as an exercise program to prevent recurrence of falls in elderly women.

Background: The gastrocnemius tightness can easily occur. Gastrocnemius tightness results in gait disturbance. Thus, various interventions have been used to release a tight gastrocnemius muscle and improve gait performance. Moreover, focal muscle vibration (FMV) has recently been extensively researched in terms of tight muscle release and muscle performance. However, no study has investigated the effects of FMV application on medial gastrocnemius architectural changes. Objects: In this study, we aimed to investigate the effects of FMV on medial gastrocnemius architecture in persons with limited ankle dorsiflexion. Methods: Thirty one persons with <10° of passive ankle dorsiflexion participated in this study. We excluded persons with acute ankle injury within six months prior to study onset, a history of ankle fracture, leg length discrepancy greater than 2 cm, no history of neurological dysfunction, or trauma affecting the lower limb. The specifications of the FMV motor were as follows: a fixed frequency (fast wave: 150 Hz) and low amplitude (0.3-0.5 mm peak to peak) of vibration; the motor was used to release the medial gastrocnemius for 15 minutes. Each participant completed three trials for 10 days; a 30-second rest period was provided between each trial. Medial gastrocnemius architectural parameters [muscle thickness (MT), fiber bundle length (FBL), and pennation angle (PA)] were measured via ultrasonography. Results: MT significantly decreased after FMV application (p < 0.05). FBL significantly increased from its baseline value after FMV application (p < 0.05). PA significantly decreased from its baseline value after FMV application (p < 0.05). Conclusion: FMV application may be advantageous in reducing medial gastrocnemius excitability following a decrease in the amount of contractile tissue. Furthermore, FMV application can be used as a stretching method to alter medial gastrocnemius architecture.

This study was carried out to recognize the understanding of high school teachers about physical therapist during September in 1988, The study population was comprised of 511 high school teachers who had lived in Seoul and Kyunggi Province. Mate teachers were $56\%$ and the rest of them were females. In age distribution $45.4\%$ of them belonged to the 3rd decade, in religion $36.2\%$ of them were Christians, and in their carrier $45.8\%$ of them were less then 5 years. The results obtained were as follows. 1. The high school teachers who knew about department of physical therapy is amounted to $62.6\%$ in male and $49.8\%$ in female. The high school teachers ($41.7\%$ in male and $38.6\%$ in female) considered that students aptitude was the most important thing to keep in mind in counselling those who wished to become physical therapists. There were difference in opinion between male and female teachers as to the counselling criteria (p<0.05). 2. The high school teachers who knew that the students would beemployed in sport center and health clubs after graduation amounted to $24.3\%$ in males and in general hospital to $27.1\%$ in female. There was significant difference in the knowledge for their field of employment between male and female teachers (p<0.05). 3. As to the effectiveness of the physical therapy, $41.3\%$ of male and $29.8\%$ of the female teachers responded to 'satisfactory', but indicating no statistical difference both sexes. 4. As for the attitude of physical therapiest, $43\%$ of them answered that kindness and service devotion were the prerequisite for them. There were statistical difference between male and female teachers in concepts about attitude (p<0.05). To the social level of physical therapist, majority of the teachers thought that physical therapist belong to moderate level in social class. 5. Those who considered that the physical therapy was necessary means for treatment of trauma amounted to $73\%$. The reason why teachers thought that physical therapy was not necessary was that it required too long period of time for the treatment. 6. Those who knew fully the job of physical therapist amounted to $55\%$ and the 55. $9\%$ knew that physical therapists work only at hospitals as the therapist and the rest of them misunderstood the job of physical therapist. 7. As for the academic background to be qualified as physical therapist, $76.2\%$ of them said that graduation of Junior College was required, $12.9\%$ graduation of Senior College and the rest of them had no ideas at all.

Purpose: The nasal bone fracture is most common fracture in facial bone injuries. Regardless of the severity or type of fracture, closed reduction has traditionally been the common method of treatment. However, through detailed pre-operative evaluation, we found out that many patients consider rhinoplasty prior to trauma due to aesthetic desire or nasal deformity with or without septal deviation. In treatment of nasal bone fracture, we focused not only on the fracture management but also on the patients' desire prior to trauma, and we made additional operation according to patients' desire with fracture reduction and gained rewarding outcomes. Methods: From March 2005 to June 2007, total 263 patients were treated for nasal bone fracture. Among these patients, 57 patients (21%) had the additional operation with nasal fracture reduction. The additional operations were categorized in three types: augmentation rhinoplasty with tip plasty (40%), septoplasty only (16%), corrective rhinoplasty (44%). The mean follow-up period was 5.6 months and results were evaluated by scoring. Results: Forty four of 57 patients (77%) were highly satisfied regardless of any additional operation kinds. The complications were one septal perforation, two displacement of implant and four remnant nasal deformities. For the septal perforation, no further management was performed because we lost the contact with the patient. Then 4 of the other complicated patients were revised. Conclusion: In general, many physicians tend to consider nasal fracture as a simple trauma. However through the strict history taking, physical examination and professional counseling, we could catch the patient's cosmetic desire and get the eyes on new concept: the nasal fracture is not only a trauma but a cosmetic and functional field. In the treatment of nasal bone fracture, if additional rhinoplasty is performed, patients will be more satisfied and we also can expect higher profits.

배경: 흉부 둔상은 전체 흉부 손상의 90%정도를 차지하며 외상과 관련된 사망률의 20%를 유발시킨다. 흉분 둔상에 의한 손상 후 이환율과 사망률의 주요 원인은 발견되지 못한 손상이 남아있기 때문이다. 그리하여 흉부전산화단층 촬영은 외상환자의 진단적 검사에서 매우 자주 사용되어져 왔다. 그러나 흉부 컴퓨터 촬영은 가격이 비싸고, 방사선 노출을 증가시킬 수 있다. 이번 연구를 통하여 흉부둔상 환자에서 흉부단순촬영과 비교하여 흉부전산화단층촬영을 통하여 얼마나 더 많은 정보를 얻을 수 있는지 조사해 보고 그리고 흉부 컴퓨터 촬영의 진단과 치료에 있어서의 역할을 알아보고자 한다. 대상 및 방법: 2006년 11월부터 2007년 7월까지 응급실로 내원한 환자 100명을 대상으로 하였다. 이 중 74명의 자동차 관련사고 환자와 26명의 낙상 사고 환자가 있었으며 흉부엑스선과 흉부전산화단층 촬영을 동시에 시행한 환자를 전체 응급실 환자 중에 선택하였다. 자료는 차트를 통하여 혈역학적 소견, 중재적 치료 여부, 손상의 중증도(RTS)와 종류를 조사하였으며, 초기 응급실 내원환자 중 흉부단순촬영과 흉부전산화단층촬영을 시행한 환자를 대상으로 발견되지 못한 병적 소견을 각각 질환별로 분석하였다. 결과: 100예의 환자 중 흉부엑스선 검사상 하나 이상의 병적소견을 보인 환자가 79예였으며 21예의 환자에서는 흉부엑스선 검사상 정상 소견을 보였으며, 이 21예의 환자 중 17예에서 흉부전산화단층촬영상 이상소견이 발견되었다. 흉부엑스선 검사상 발견하지 못한 소견으로는 기흉, 혈흉, 폐좌상, 흉골 골절 등이 있었으며 이러한 병적 소견의 진단은 흉부전산화단층촬영이 흉부엑스선 검사보다 통계적으로 유의하게 우수한 것으로 나타났다. 하지만 치료에 있어서는 흉부전산화촬영 시행 후 발견된 병변으로 흉관삽입술등의 치료를 시행한 환자는 31명에 불과했고 흉관삽입술, 개흉술 등의 흉부외과적인 치료 없이 집중관찰을 위하여 입원한 환자가 42명이었으며, 흉부엑스선촬영과 환자의 이학적 소견으로 진단되어 치료를 시행한 환자가 27명이었다. 결론: 흉부전산화단층촬영은 진단에 있어서 흉부엑스선 촬영보다 통계적으로 의미 있게 진단에 도움이 되는 것을 알 수 있었으나 발견되지 못한 병변이 증가할지라도 치료의 변화와 방법의 변화가 있는 경우는 매우 소수에 불과했다. 그리하여 응급실에서의 흉부전산화단층촬영의 오남용을 막기 위하여 선별적인 흉부전산화단층 촬영을 고려해야 할 것이다.

With the introduction of the video display terminal (VDT), the efficiency and productivity of work has improved. However, VDT syndrome is threatening the health of workers as a side effect of prolonged use of a VDT. Among various VDT syndromes, the musculoskeletal disorder, especially, the cumulative trauma disorder (CTD) is the common research topic related with upper extremities function. The aim of this study was to investigate the effect of the wrist-hand orthosis (WHO) on fatigue in middle deltoid, anterior deltoid, serratus anterior, and upper trapezius during one-hour computer keyboard typing. Twelve healthy subjects participated in this study. Surface electromyography was used to assess the localized muscle fatigue (LMF), and the LMF was calculated at 10 minutes, 20 minutes, 40 minutes, and 60 minutes in each muscle, with and without the WHO. Data were analyzed by paired t-test with a level of significance of .05. The results of this study are as follows: 1) At 10 minutes, the LMF decreased significantly with applied WHO in the middle deltoid, anterior deltoid, and upper trapezius (p=.001, p=.026, p=.019, respectively). 2) As the computer keyboard typing period increased, there were no significant LMF differences, except for the upper trapezius. Therefore, it can be concluded that the WHO can be applied to decrease the LMF for the initial 10 minute period in the middle deltoid, anterior deltoid, and upper trapezius' but that the long term effect of WHO in reducing the LMF was proven only in upper trapezius during continued computer keyboard typing.

Purpose: The objective of this study was to offer clinical primary data that it's aims to examine effects of transcranial direct current stimulation (tDCS) on cognitive function and biochemical change of rat with alzheimer's disease(AD) induced by injecting scopolamine. Methods: Subjects were instructed cognitive dysfunction model, rat of Sprague-Dawley system was injected with scopolamine and each experimental group was classified into three; group I (n=16) is non-treatment groups; group II (n=16) is applied with the tacrine; group III (n=16) is applied with the tDCS. The ziggurat task test was conducted to observe behavioral changes and cognitive function ability and 7, 14, 21, 28 days after the model. Acetylcholine Esterase (Ach E) activity was examined for biochemical assessment of which the results are followed. Results: Participants showed as to behavioral change, tacrine application group was the most significantly responded, following tDCS application group. As to biochemical change, same as above, tacrine application group was the most significantly responded, following tDCS application group. Conclusion: From these results, confirm that tDCS application to rat with alzheimer's disease leads to positive effects on behavioral, cognitive function changes, and biochemical changes, lasting for certain period of time. This study, in particular, tDCS, which can change excitability of brain cells non-invasively, could provide basic data that is useful as a new treatment way for the patients with cognitive dysfunction.
