Objectives: Pedestrian traffic injuries have been an important cause of childhood mortality and morbidity for decades. The aim of this study was to describe the epidemiological characteristics of child pedestrian traffic injuries that occurred during 2000 in one metropolitan city and its school-zones, and to determine the factors associated with those accidents. Methods: A cross-sectional study was performed in 2001. Police records were used to identify the cases of pedestrian injury. Children aged between 6 and 15 years, injured during road walking, were included in this study. A direct survey of the environmental factors within the school-zones in study area (n=116) was also performed. Self-administered questionnaires, via mail and telephone surveys, were used to assess the safety education programmes. The schools were divided into two groups according to the occurrence of pedestrian traffic injuries in their school-zone. Results: Pedestrian injuries (n=597) were found to account for 3.2% of all traffic injuries in the subject area. The epidemiological characteristics were not significantly different between genders. There were some significant risk factors within the environmental factors, such as local road (OR: 2.3, 95% CI=1.05-5.35), heavy traffic volume (OR: 2.2, 95% CI=1.00-5.04), poor visibility of speed-limit signs (OR: 2.8, 95% CI=1.25-6.42), no separation of pedestrian routes from cars (OR: 2.6, 95% CI=1.02-6.75) and barriers on the pedestrian routes (OR: 2.2, 95% CI=1.01-5.08). Only one factor, that of education in a safety-park (OR: 0.3, 95% CI=0.09-0.96), was significantly associated in the traffic and pedestrian safety education factors. Conclusion: Significant associations with pedestrian injury risk were identified in some of the modifiable environmental factors than in the educational factors.

The objective of this study was to discover the effects of the short-term home visiting physical therapy program involving patients with some chronic brain disorders at Gimhae City, Kyongnam. Recovery of activities of daily living (ADL) is a very important factor of rehabilitative procedures, and Functional Independence Measure (FIM) is a useful standard of evaluation for it. The FIM is widely used in brain disorder research because it measures real functional activities of daily living. We applied the physical therapy exercise program twice per week (10~15 times repeatedly); a warm-up and cool down exercise performed every ten minutes by active & active-assistive ROM and stretching exercises. Main exercises were composed of getting up & laying down in bed, standing training, walking exercise in the room, and window or wall sliding exercise using affected upper limbs for a total duration of 30 minutes. We collected the data from 20 patients with chronic brain disorders at his/her home and analyzed by means of SPSS/PC+ program (Ver. 10.0). After the six week long physical therapy exercise program, the average was $56.10{\pm}22.59$ point compared with initial $50.55{\pm}19.12$ point by FIM, improved functional ADL ability about 5.55 point, and these changed scores were statistically significant (p=.000). We also studied another factor regarding patient's satisfaction. The majority of subjects (10 people) rated the program with the maximum score of ten points (50.0%), and three people rated it a seven point program (15.0%), the other two subjects gave a rating of nine and eight points (10.0%). Because the program was effective at improving the physical ADL ability and satisfaction of each subject, we suggest continual development and implementation of a home visiting physical therapy program. Further study should involve a longer period of observation with a larger population that is involved in an individually designed home physical therapy program.

The purpose of this study is to research on concept, consisting factors, and specialties of theme park' character costumes to understand better about character costumes as well as to establish fundamental research data. The characteristics of character costumes in the theme park are as follows. First, theme park' character costumes are personified so that visitors may feel friendly and have emotional communication with them. Specially, costume that anthropomorphize an animal(85.3%) and silhouette of lozenge style(86.8%) dominated the highest weight. Animal figures are walking upright and wearing human's clothes. They communicate with visitors using mime actions. Second, various types of body proportion is applied to highlight the characteristics of character costume. Most character costumes are applied with unrealistic body proportion. This unrealistic body proportion give abnormal image and looks funny. The important factor is size of their head. Especially, 3.5 body proportion(78.9%) is general. Third, simplification, exaggeration, shrinkage, and modification are other factors. Simplification is applied differently by parts. Pocket, collar details are simplified to clarify the character's image. More simplification can lead to ommission. For their head, peculiar parts look stand out but other parts are simplified to stress their characteristics. Exaggeration is used with shrinkage to give strong impression to visitors. Forms are broken intentionally and they are modified. They look impressive because they are not harmonized. It is unexpected image and induces humor and familiar feelings. Matter of stylization includes exaggeration, shrinkage, modification and movement of actors that have tangible factor of character costume.

본 연구는 동작 속도별 마찰음의 주관적 평가에 있어서 시각적 변수의 영향을 분석하는 것을 목적으로 한다. 현재 유통되고 있는 79 종의 스포츠웨어용 투습발수직물 중 음향 특성으로 계층적 군집분석에 의해 나누어진 3 개의 군집에서 각각 하나씩 추출한 총 3가지 시료를 대상으로 walking, jogging, running의 속도로 마찰시켜 총 9가지의 소리에 대하여 실험하였다. 직물 소리에 대한 주관적 평가 시 시각적 변수의 영향을 분석하기 위하여 두 가지 방법으로 직물 소리에 대한 주관적 반응을 평가하였다. 첫 번째는 기존의 연구에서 주로 이루어진 방법으로, 실험 진행자가 피험자에게 직물소리를 들려주면서 설문을 하게 하였다. 두 번째는 녹음된 직물의 소리와 함께 모니터를 통해 해당 자극물의 마찰 속도에 따라 인체 모델이 움직이는 동작을 보여줌으로써 청각과 시각 자극을 동시에 제시하여 주관적 평가의 자극물로 사용하였다. 주관적 평가는 8개의 형용사 쌍에 대해 의미미분척도로 평가되었고, 두 가지 방법을 비교하기 위하여 '실제 옷을 착용하고 움직일 때 발생하는 직물 소리와 유사하게 들린다.' 와 '옷을 착용하고 움직일 때 발생하는 소리라고 느껴진다.' 두 문항을 추가하여 평가하였다. 그 결과 시각 자극의 유무에 의한 감성평가 결과에는 큰 영향을 미치지는 않았지만, 피험자가 소리만으로 직물이 마찰되는 장면을 의식적으로 상상해야 하는 심리적 부담을 줄여주었고, 주관적 평가 몰입도를 향상시켰다고 사료된다.

Purpose: The purpose of this study was to identify the risk factors for falls and to suggest data for developing a program for preventing falls. Methods: This was a case-control study in five university hospitals and a general hospital. In total, 216 patients over the age of 18 yr admitted from January 1 to December 31, 2007 participated. One hundred eight patients with experience of falling were matched by gender, age level, diagnosis, and length of stay with 108 patents with no experience of falling admitted on the same unit. A quality assurance coordinator nurse in each hospital examined 35 fall risk factors developed by researchers. Results: In acute hospitals, history of falls, orientation ability, dizziness or vertigo, general weakness, urination problems, transfer/mobility difficulty, walking dependency, impatience, benzodiazepines, diuretics, and vasodilators showed significance on adjusted-odds ratios for fall. Logistic regression analysis was performed to elucidate the factors that influence falls. The probability of falls was increased by dizziness/vertigo, general weakness, and impatience/agitation. Conclusion: This finding can be used as a useful resource in developing nursing intervention programs to predict and prevent the falls of inpatients.

Stretchable strain sensors are becoming essential in diverse future applications, such as human motion detection, soft robotics, and various biomedical devices. One of the well-known approaches for fabricating stretchable strain sensors is to embed conductive nanomaterials such as metal nanowires/nanoparticles, graphene, conducting polymer and carbon nanotubes (CNTs) within an elastomeric substrate. Among various conducting nanomaterials, CNTs have been considered as important and promising candidate materials for stretchable strain sensors owing to their high electrical conductivity and excellent mechanical properties. In the past decades, CNT-based strain sensors with high stretchability or sensitivity have been developed. However, CNT-based strain sensors which show both high stretchability and sensitivity have not been reported. Herein, highly stretchable and sensitive strain sensors were fabricated by integrating single-walled carbon nanotubes (SWNTs) and nylon textiles via vacuum-assisted spray-layer-by-layer process. Our strain sensors had high sensitivity with 100 % tensile strain (gauge factor ~ 100). Cyclic tests confirmed that our strain sensors showed very robust and reliable characteristic. Moreover, our SWNTs-based strain sensors were easily and successfully integrated on human finger and knee to detect bending and walking motion. Our approach presented here might be route to preparing highly stretchable and sensitive strain sensors with providing new opportunity to realize practical wearable devices.

Objective : We have limited understanding on the presentation and survival of primary spinal sarcomas. The survival, recurrence rate, and related prognostic factors were investigated after treatment for primary sarcomas of the spine. Methods : Retrospective analysis of medical records and radiological data was done for 29 patients in whom treatment was performed due to primary sarcoma of the spine from 2000 to 2010. As for treatment method, non-radical operation, radiation therapy, and chemotherapy were simultaneously or sequentially combined. Overall survival (OS), progression free survival (PFS), ambulatory function, and pain status were analyzed. In addition, factors affecting survival and recurrence were analyzed : age (${\leq}42$ or ${\geq}43$), gender, tumor histologic type, lesion location (mobile spine or rigid spine), weakness at diagnosis, pain at diagnosis, ambulation at diagnosis, initial treatment, radiation therapy, kind of irradiation, surgery, chemotherapy and distant metastasis. Results : Median OS was 60 months, the recurrence rate was 79.3% and median PFS was 26 months. Patients with distant metastasis showed significantly shorter survival than those without metastasis. No factors were found to be significant relating to recurrence. Prognostic factor associated with walking ability was the presence of weakness at diagnosis. Conclusion : Primary spinal sarcomas are difficult to cure and show high recurrence rate. However, the development of new treatment methods is improving survival.
