Purpose: Translation and adaptation involve cross-cultural and conceptual aspects; they are not simply based on linguistic equivalence. This study aimed to produce a conceptually equivalent Korean version of the motor activity log (K-MAL) for the upper extremities that can be applied across the Korean population and its cultures. Methods: Following the procedures used in the translation of other cross-cultural evaluation tools, and the five steps of the translation process, the motor activity log (MAL) was translated into Korean (K-MAL). We then examined the content validity of the K-MAL. Twenty-two rehabilitation professionals (11 males and 11 females, mean length of clinical career = 101.54 months) assessed the content validity of the K-MAL. The content validity ratio and content validity index were used to verify the content validity. Results: There were inconsistencies found in three sub-items in the MAL during the forward translation process. These inconsistencies were corrected, and the complete K-MAL was produced. The exact critical values of the content validity ratio and the content validity index of the K-MAL were 0.45-0.95 and 0.77-1.00, respectively. Conclusion: The K-MAL was successfully developed using a systematic methodology, which included translation, adaptation, and evaluation of the content validity. We expect that stroke rehabilitation professionals working in both clinical and research settings will apply the K-MAL when evaluating the amount and quality of use of the upper extremities in post-stroke patients in Korea.

Purpose: The purpose of this study was to develop a Korean version of the Falls Efficacy Scale (K-FES), which is used to measure the fear of falling, that is conceptually equivalent to the original and culturally adaptable to the Korean population. Methods: A five-step translation and adaptation process was employed to create the K-FES, adhering to the established guidelines for cross-cultural rehabilitation outcome measures. The content validity was then evaluated by 22 rehabilitation professionals (15 males and 7 females) with an average clinical experience of 201 months at neurological rehabilitation centers. The content validity ratio and index were used as a basis for judgment. Results: The translation process identified inconsistencies with the terms "objects" and "telephone" in the original Falls Efficacy Scale, which were subsequently resolved in the final K-FES version. The content validity ratios for the original, second, and third versions of the K-FES ranged from -0.27-0.91, -0.27-0.91, and -0.27-0.91, respectively. Correspondingly, the content validity index values for the original, second, and third versions of the K-FES ranged from 0.77-1.00, 0.68-1.00, and 0.63-1.00, respectively. Conclusions: The K-FES was rigorously developed through translation, adaptation, and validation processes, making it a reliable tool for Korean stroke rehabilitation professionals. It is expected to be instrumental in clinical and research settings to assess postural stability and fall risk in patients with strokes and brain injuries.

Purpose : The purpose of this study was to provide information for developing a rehabilitation intervention that improves adaptation and the quality of life after mastectomy by investigating the level of physical function and fatigue in mastectomy patients. Methods : The subjects were 63 patients selected from St. Mary's Kangnam hospital Data were collected from March to June, 2003. Physical function was measured by the range of motion of the shoulder joint, shoulder function, and physical symptoms. fatigue was measured by using the Brief Fatigue Inventory (BFI). Results : The range of motion on the affected side was significantly lower than that in the healthy side. Shoulder function score was highest in the item of 'pull on pants', and lowest in the item of 'back zipper'. Physical symptom score was highest in the item of 'numbness', and lowest in the item of 'Itching sensation'. The highest item interfered by fatigue was 'normal work (includes both work outside the home and daily chores)'. Conclusion : The result of this study suggests that effective rehabilitation intervention for mastectomy patients should be needed to improve physical function, and reduce fatigue.

The self-report measure is a useful tool for evaluating self-recognized disability and difficulty in daily living activities. Although many studies and clinics used the Neck Pain and Disability Scale (NPDS) for measuring neck pain and functional impairment, there has not been much adaptation of this for use with Korean patients. The purpose of this study was to establish the reliability and validity of NPDS among Korean neck pain patients. Fifty-five subjects (32 males, 23 females) with neck pain enrolled in this study. They completed standardized self-administered questionnaires. The NPDS measures pain intensity; its interference with vocational, emotional, recreational, social, and functional aspects of living; and the presence and extent of associated factors. Reliability was determined by the intraclass correlation coefficient (ICC) and Cronbach's alpha for internal consistency. Validity was examined by correlating the NPDS scores to the Visual Analog Scale (VAS) score. The test-retest reliability of the translated versions of the NPDS was good ICC (2,1)=.86 (95%CI .76~.92). Cronbach's alpha value for NPDS was found to be .93, and this was statistically significant (p<.05). The criterion-related validity coefficient was .79 (p<.Oll. We conclude that the Korean version of NPDS has been shown to be a reliable and valid instrument for the assessment of neck pain. Successful linguistic and cultural translation will admit appropriate cross-cultural comparison for clinical analysis. Therefore, this study can be expected to be used as an adequate evaluation scale for neck pain related studies and treatments.

Background: Physical exercise is known to cause significant joint changes. Thus, monitoring joint behavior of athletic horses is essential in early disorders recognition, allowing the proper management. Objectives: The aims of this study were to determine the morphological patterns, physical examination characteristics and ultrasound findings of show jumping horses in training and to establish a score-based examination model for physical and ultrasound follow-ups of metacarpophalangeal joint changes in these animals. Methods: A total of 52 metacarpophalangeal joints from 26 horses who were initially in the taming stage were evaluated, and the horses' athletic progression was monitored. The horses were evaluated by a physical examination and by B-mode and Doppler-mode ultrasound examinations, starting at time zero (T0), which occurred concomitantly with the beginning of training, and every 3 months thereafter for a follow-up period of 18 months. Results: The standardized examination model revealed an increase in the maximum joint flexion angles and higher scores on the physical and ultrasound examinations after scoring was performed by predefined assessment tools, especially between 3 and 6 months of evaluation, which was immediately after the horses started more intense training. The lameness score and the ultrasound examination score were slightly higher at the end of the study. Conclusions: The observed results were probably caused by the implementation of a training regimen and joint adaptation to physical conditioning. The joints most likely undergo a pre-osteoarthritic period due to work overload, which can manifest in a consistent or adaptive manner, as observed during this study. Thus, continuous monitoring of young athlete horses by physical and ultrasound examinations that can be scored is essential.

BACKGROUND: Temperature is known to be the main factor affecting development, growth and reproduction of organisms and also a physical factor directly related to insect survival. Insects as ectothermal species should be responsive to climate changes for their survival and develop various survival strategies under the unfavorable temperature such as low temperature. The purpose of this study is to identify genes contributing to adaptation of low temperature. METHODS AND RESULTS: To identify genes contributing to adaptation of low temperature, the transcriptomic data were obtained from fat body in Plutella xyostella larvae via next generation sequencing. We identified structural proteins, heat shock proteins, antioxidant enzymes, detoxification proteins, and cryoprotectant mobilization and biosynthesis-related proteins. Genes encoding chitinase, cuticular protein, Hsp23, chytochrome protein, Glutathione S transferase, and phospholipase 2 were up-regulated under low temperature. Proteins related to energy metabolism such as UDP-glycosy ltransferase, trehalase and trehalose transporter were down-regulated. CONCLUSION: When insect pests were exposed to low temperature, changes in gene expression of fat body could provide some hints for understanding temperature adaptation strategies.

In this paper, we propose an unequal protection physical coding sub-layer (PCS) forward error correction (FEC) scheme for efficient and high-quality transmission of video data over optical access networks. Through identifying and resolving the unequal importance of different video frames and passing this importance information from MAC-layer to PCS, FEC scheme of PCS can be adaptive to application-layer data. Meanwhile, we jointly consider the different channel situations of optical network unit (ONU) and improve the efficiency of FEC redundancy by channel adaptation. We develop a theoretical algorithm and a hardware method to achieve efficient FEC assignment for the proposed unequal protection scheme. The theoretical FEC assignment algorithm is to obtain the optimal FEC redundancy allocation vector that results in the optimum performance index, namely frame error rate, based on the identified differential importance and channel situations. The hardware method aims at providing a realistic technical path with negligible hardware cost increment compared with the traditional FEC scheme. From the simulation results, the proposed Channel and Application-layer data Adaptation Unequal Protection (CAAUP) FEC scheme along with the FEC ratio assignment algorithm and the hardware method illustrates the ability of efficient and high-quality transmission of video data against the random errors in the channel of optical access networks.

Fuzzy logic control(FLC) is composed of three parts : fuzzy rule-bases, membership functions, and scaling factors. Well-defined fuzzy rule-base should contain proper physical intuition on the plant, so are needed lots of experiences of the skillful expert. When membership functions are considered, some parameters on the memberships function such as function shape, support, allocation density should be selected well. The rule of scaling factors is 'scaling'(amplifying or reducing) for both input and output signals of the FLC to fit in the membership function support and to operate the plant intentionally. To get a better performance of the FLC, it is necessary to adjust the parameters of the FLC. In general, the adaptation of the scaling factors is the most effective adjustment scheme, compared with that of the fuzzy rule-base or membership function parameters. This study proposes the adaptation scheme of the scaling factors. When the adaptation is performed on-line, the stability of the adaptive FLC should be guaranteed. The stable FLC system can be designed with stability analysis in the sense of Lyapunov stability. To adapt the scaling factors for the error signals, the concept of the conventional MRAC would be introduced into slightly modified form. A tracking accuracy of the control system would be enhanced by the modified shape and support of the membership function. The simulation is achieved on the pilot plant with the hydraulic steering control of a UCT(Unmanned Container Transporter) of which modeling dynamics have lots of severe uncertainties and modeling errors.

Purpose: This study was conducted to examine the relationship between stress and quality of life of family caregivers of patients with lung cancer. Methods: From April 18 to May 4, 2009, data were collected using self-report questionnaires with 95 family caregivers of lung cancer patients in G cancer center. The data were analyzed using descriptive statistics, t-test, ANOVA and pearson's correlation coefficient with SPSS 14.0. Results: The mean score of the stress level was 27.5 (SD=14.77). The mean score of the QOL was 73.0 (SD=17.86). The stress level of family caregiver showed significant difference according to gender (psychological stress p=.011, total level of stress p=.042) and availableness of second caregiver (physical stress p=.023, psychological stress p=.035, total level of stress p=.001). The QOL of family caregivers showed significant difference according to daily caring (positive adaptation p=.045) and financial burden on treatment expense (positive adaptation p=.004, total quality of life p=.043). The negative correlation was found between stress and QOL of family caregivers (r=-.67, p=.032). Conclusion: These results indicate a need to develop nursing intervention programs for family caregivers to reduce stress and improve QOL.
