The purpose of this study was to investigate the relationship between neck pain and upper limb disability in patients with non-specific neck pain (n=132) recruited from physiotherapy departments in the Korea. Baseline neck pain/disability was measured using the Northwick Park Neck Pain Questionnaire (NPQ) and upper limb disability was measured using the Disabilities of Arm, Shoulder, Hand questionnaire (DASH). A range of baseline psychosocial variables were measured as potential confounding variables. Pairwise analysis revealed a positive correlation between NPQ score and DASH score (Pearsons' r=0.628, p<0.05). This study provides preliminary evidence that patients with severe neck pain/disability also report severe upper limb disability. The presence of severe neck pain or low pain self efficacy and high fear-avoidence beliefs questionnaire should clinicians towards a careful examination of upper limb function in patients presenting with neck pain. Our data suggest the upper limb disability may need to be addressed as part of the neck management process.

Objectives: This study investigated musculoskeletal symptoms in upper limbs according to the working environment (job stress) of dental hygienists and examine their relationship with upper limb functions. Methods: The subjects include 198 dental hygienists in dental hospitals and dental clinics in Pusan and Gyeongnam. The questionnaire was consisted of general characteristics of the subjects, job stress, musculoskeletal symptoms in upper limbs and function (Disability Measurement Tool for Upper Extremity Disorders-11, DASH-11). Results: The study was analyzed their musculoskeletal symptoms in upper limbs according to their general characteristics and found that the symptoms occurred in the neck (39.4%), the shoulders (54.6%), elbows (14.7%), and the hands (50.0%). Job stress was associated with upper limb functions (DASH-11) (model 3, B=5.210, p=0.012) and repeated elbow bending and spreading posture was associated with DASH-11 (model 3, B=6.561, p=0.029). Elbow symptoms were associated with DASH-11 in the upper limbs (B=10.679, p=0.003). Conclusion: Dental hygienists are experiencing limitations of upper limb function due to job stress. In particular, even if the correction of their uncomfortable posture is significantly related to the job stress and upper limb function, in order to improve the upper limb function of the dental hygienist, efforts to reduce the job stress as well as the uncomfortable posture are necessary.

In the era of ultra high speed information communication technology represented by Smart phone and Tablet PC, the disable and the aged people came to be in a position of so-called 'relatively weak people' in the field of information communication due to inconvenience of use and difference in information acquisition and processing ability. Thus, a survey was conducted on Smart phone accessibility items based on previous studies of the disabled with crippled disorder, brain lesions, myelopathy and muscular disabilities having more inconvenience relatively in their use of smart phone due to upper limb dysfunctions. Especially, people with upper limb dysfunctions with relatively weak grip had big inconvenience in the conditions of uses requiring actions such as grabbing and rotating the devices, and due to the characteristics of touch screen input method of Smart phone, they had big inconvenience due to a lack of a guidance for keyboard in input. As a result of questionnaires by the type of disability, it turned out that severe myelopathy causes the most inconvenience in using smart phone.

The aim of this study was to examine the relationships between upper limb muscle strength and cognitive function in older Korean adults. A total of 130 Community-dwelling older adults, who were able to independently conduct activities of daily living, participated in the study. We assessed upper limb muscle strength using a handgrip strength and arm curl test, and their cognitive function using a Montreal cognitive assessment (MoCA) and general practitioner assessment of cognition (GPCOG) tests. Out of 130 participants, 26 (20%) had normal cognitive functions, while 104 older adults (80%) had mild cognitive impairments (MCI). Handgrip strength was significantly different between older adults with and without MCI (p<.05) and was related to MoCA and GPCOG (p<.05). In the result, there is a correlation between physical ability and cognitive function of the older adults. Therefore, it is necessary to develop exercise program to improve mental health.

This study was carried out to identify the factors which correlated with upper limb function after stroke and to analyze the effect of related factors on upper limb function. The 100 stroke patients(MMSE-K>24) were participated. The upper limb function according to gender, hand dominance, stroke type, affected location, site of paralysis, speech disorder showed no significant difference, and show significant difference according to shoulder subluxation. The upper limb muscle strength(Manual Muscle Testing), proprioception, muscle tone(Modified Ashworth Scale), grip strength(Dynamometer), paint (Visual Analog Scale) showed significant correlations with upper limb function. These predictors explained 77.6% of the upper limb function and the most significant affecting factor of upper limb function was upper limb muscle strength. In conclusion, the upper limb muscle strengthening will be effective strategy to improving the upper limb function and considering the proprioception, muscle tone, grip strength, pain, subluxation will be helpful to develop the strategies.

The purpose of this study was to investigate the effects of virtual reality game based training on balance and upper limb function in subacute stroke patients. Thirty patients with subacute stroke were randomly assigned to experimental groups(n=15) and control groups(n=15) applying virtual reality game-based training programs. Intervention is applied three times a week for 6 weeks, 30 minutes for 1 time. In the study group, there was a significant improvement in balance ability, upper extremity function, and trunk impairment scale(p<.05), and the difference between the two groups was significant in the BBS, TUG, TIS(p<.05). Based on these results, the virtual reality game based training program is clinically useful exercise program for subacute stroke patients.

Objective : The purpose of this study is to investigate the impact of task-oriented approach based on upper limb coordinated movement on the ability of the Korean handwriting in children with developmental coordination disorder(DCD). Methods/Design : This randomized controlled trial designed as a pre-/post- test will compare the effectiveness of task-oriented approach and process-oriented approach on handwriting performance for children with DCD aged 5 to 10. These interventions consist of 10 training sessions and 4 assessment sessions over 7weeks. Children will be measured regard to handwriting legibility, speed and pre-handwriting skills including upper limb movement skills, visual perception and visual motor coordination. Conclusion : This is the first attempt to investigate effects of a task-oriented approach in children with DCD. The significance of this study is to provide the clinical evidences to apply the task-oriented approach improves the children's handwriting performance. Furthermore it will also present a more effective intervention for handwriting by figuring out each approach's impact on the improvement of pre-handwriting skills.

For reducing greenhouse gases, many countries carried out a series of activities not only at home but abroad. Particularly, after the release of the Kyoto Protocol, either nation or companies' participation was intensified, due to endow to responsibility of emission limits. This study focused on reforestation CDM work in Goseong Gun based on clean development system. Obstacle factors of land eligibility could be distinguished to three periods: before December 31th 1989, present and future. The obstacle before December 31th 1989 was that land cover of study area hardly illustrated by Landsat image, due to the low resolution, which were confirmed by a document of Grassland Composition Permission instead. The problem of current land eligibility is that the area of trees presence are difficult to be determined as forest or not. The boundary of forest in strata was identified, using 3-Dimensional Cartography Machine and aerial photograph. Land eligibility would still have obstacle whether the study area with trees presence has potentiality to be forest in the future at situation in absence of reforestation project. This was resolved by prediction of tree growth using stem analysis during execution of the project at study area.
