Purpose: This research was carried out to evaluate the validity and reliability of the Korean version of the Summary of Diabetes Self-Care Activities Questionnaire (SDSCA) for Korean older adults with type 2 diabetes. Methods: Translation and back-translation were performed to develop the Korean version of the SDSCA. Then the Korean version SDSCA was applied to a sample of 112 older adults who had participated in diabetes self management education in Seoul. The internal consistency and the test-retest reliability were examined to test the reliability. Factor analysis was used to examine the construct validity. Results: The internal consistency measured with Cronbach's alpha was .77 and the total test-retest reliability was .68 with items ranging from .21 to 1.00. As the result of the factor analysis, six factors -foot care, diet, exercise, blood sugar test, medication, and smoking- were revealed as the original instrument subcategories. These six factors explained 81.17% of total variance. Conclusion: The reliability and validity of the Korean version SDSCA Questionnaire was supported for use in older patients with type 2 diabetes in Korea.

본 논문에서는 스테레오 영상 기반에서 능동 특징점 모델(active feature model)과 광류(optical flow)를 이용한 객체 추적 기술을 제안한다. 스테레오의 기하학적 정보와 변위를 이용하여 관심 객체와 특징점의 2.5차원 이동 정보(translation information)를 계산한다. 이 정보를 이용하여 폐색 객체의 특징점의 이동 정보를 예측하여 추적 성능을 개선하였다. 정형(rigid) 및 비정형(non-rigid) 객체에 실험을 하였다. 실험 결과 복잡한 배경 속에서의 실시간 객체 추적이 가능하였다. 또한 정형, 비정형 객체에 관계없이 추적이 가능 하였으며 폐색 상황에 향상된 결과를 보였다.

Purpose: The purpose of this study was to test the validity and reliability of the Diabetes Self-Care Barriers Assessment Scaler for Older Adults (DSCB-OA) in Korean older adults with type 2 diabetes. Method: To develop Korean version DSCB-OA used translation and back-translation method. Then, Korean version DSCB-OA was analyzed using data of 278 older adults with type 2 diabetes. Cronbach's alpha coefficient, item to total correlation and test-retest reliability was used for the reliability test, and factor analysis was used for the construct validity. Results: Cronabach's alpha of the DSCB-OA was.77, and item to total correlation coefficient ranged from -.13 to.56. The results of factor analysis showed DSCB-OA consisted of four factors(diet, exercise, blood sugar test, treatment) which explained 62.8% of total variance. Conclusion: The Diabetes Self-Care Barriers Assessment Scaler for Older Adults (DSCB-OA) was confirmed helpful tool for Korean older adults with type 2 diabetes.

Purpose : The purpose of this study was to analyze the dynamic range of motion (ROM) of pelvic and translation of center of mass (COM) when wearing different shoe insole lifts according to leg length discrepancy (LLD) during free speed gait. Methods : Thirty-five healthy adults were participated in this study. Kinematic data were collected using a Vicon motion capture system. Reflective and cluster 40 markers attached to participants lower extremities and were asked to walk in a 6 m gait way under three different shoe lift conditions (without any insole, 1 cm insole, and 2 cm insole). The pelvic ROM and COM translation in three planes were sorted using a Nexus software, and a Visual3D motion analysis software was used to coordinate all kinematic data. Results : There were significantly increased maximal pelvic elevation and total pelvic range in coronal plane when wearing a standard shoe with 2 cm insole lift during gait (p<.05). When wearing a standard shoe with 2 cm insole lift, the total range of the pelvic segment were significantly different in all three motion planes (p<.05). Conclusion : Although LLD of less than 2 cm develops abnormal movement pattern of the pelvis and may cause of musculoskeletal diseases such as low back pain, hip and knee joint osteoarthritis, therefore intensive various physical therapy interventions for LLD are needed.

의미 수행 코드를 이용한 문법-지시적 변환 방법은 컴파일러 설계자가 원시 언어의 구문 구조에 따라 직접 컴파일러의 후단부를 표현할 수 있는 효과적인 방법으로 텍스트 프로그래밍 언어에서는 컴파일러 구축 방법으로 널리 사용되고 있다. 그럼에도 불구하고 시각언어의 경우에는 통합된 파스 트리 노드 표현 방법의 부족과 구문 구조의 모델링 방법의 결여로 인하여, 의미 수행 코드를 이용한 문법 지시적 변환 방법에 기반을 둔 컴파일러 구축에 어려움이 있다. 본 연구에서 는 Pictorial Class Grammar의 시각언어 구문 정의를 캡슐화 하는 방법과 And-Or-Waiting Graph를 이용한 구문 분석 방법을 기반으로 하여, 구문 요소를 하나의 클래스형태로 구성함으로써, 구문 요소의 표현에 사용되는 의미와 구문의 미 (syntax-semantics)를 분리 할 수 있는 방법을 제시한다. 이 방법에 기초하여 기존 연구들의 문법-지시적 시각언어 컴파일러 구축의 문제점을 극복하고, 구문 명세와 분리된 의미 수행 코드 명세 방법을 제시하여, 유지보수성을 보다 향상시킨 문법-지시적 변환 방법을 이용한 시각언어 컴파일러 자동 생성 방법을 제공한다.

The purpose of this study was to determine the reliability and validity of the fear-avoidance beliefs questionnaire (FABQ) in assessing Korean patients with low back pain. We performed translation and cross-cultural adaptation of the questionnaire and enrolled 52 patients (18 males and 34 females) with low back pain. The subjects completed a standardized self-administered questionnaire that included the FABQ assessment along with evaluations for the visual analogue scale (VAS), Oswestry disability index (ODI), self-rating anxiety scale (SAS), and Beck depression inventory-Korean version (K-BDI). The reliability of the obtained data was determined by evaluating the internal consistency on the basis of the intraclass correlation coefficient (ICC) and the Cronbach's alpha values, while the validity of the data was examined by correlating the FABQ scores to the VAS, ODI, SAS, and K-BDI scores. The translated versions of the FABQ showed good test-retest reliability: ICC (3, 1)=.90 (FABQ for physical activity) and .97 (FABQ for work) these values were statistically significant (p<.01). The Cronbach's alpha value for FABQ was .90 (p<.01). FABQ moderately correlated with pain, disability, anxiety, and depression (p<.01). The results of this study indicate that the Korean version of the FABQ is a reliable and valid instrument for measuring fear-avoidance beliefs in Korean patients with low back pain.

A fungus was isolated from field soil collected from Daegu, Korea. The colony of the isolated fungus showed short, branched, and light to dark yellow pigments with hyaline, yellowish red to orange brown aerial mycelia. In addition, the fungus produced solitary to aggregated perithecia, ovoid to pyriform, short neck, and asci as well as biseriately arranged ascospores. Phylogenetic analysis using the internal transcribed spacer region and translation elongation factor $1-{\alpha}$ sequences and morphological characteristics identified the isolated fungus as Penicillifer diparietisporus, which belongs to the family Nectriaceae. To our knowledge, this is the first report of Penicillifer diparietisporus in Korea.

In this paper, we present a novel method for reconstructing a super-resolution image using multi-view low-resolution images captured for depth varying scene without requiring complex analysis such as depth estimation and feature matching. The proposed method is based on the iterative back projection technique that is extended to the 3D volume domain (i.e., space + depth), unlike the conventional superresolution methods that handle only 2D translation among captured images.

In 2008, leaf blight symptoms were observed on several Chinese chive farms in Sangju. The Pathogenicity of the isolate was confirmed by artificial inoculation, where the pathogen exhibited a strong pathogenicity toward healthy plants. Morphological classification identified the isolate as from the Fusarium genus. For further analysis, PCR and phylogenetic classification were performed with ITS region and 28S rRNA gene which are commonly used for fungal identification. However, the results provided a poor resolution. To solve this problem, we analyzed translation elongation factor 1-alpha (TEF-$1{\alpha}$) gene. The analyzed results using TEF-$1{\alpha}$ gene indicated that the isolate was F. proliferatum. Therefore, it is assumed that TEF-$1{\alpha}$ gene is important when Fusarium sp. was identified using molecular classification method.
