Reinforcing bar coupling method has a variety of ways including lap-splice method. However, there are problems that need to be improved in terms of constructability, economics analysis. We should be improved about the problems of the existing methods. Accordingly, this study were developed a new type of staggered grip type reinforcing bar coupling. The proposed method show the following effects than existing methods. First, this method can be reduce time through improved workability. Second, increasing safety through the slip removal. Third, improving economic efficiency by reduce the manufacturing costs.

Purpose: The purpose of this study was to investigate the effects of the scapulothoracic mobilization on subject with lateral epicondylalgia. This was done through lateral slide scapular test, grip strength, visual analogue scale, glenohumeral joint external rotation range of motion. Methods: Before the experiment, Lateral slide scapular test, grip strength, visual analogue scale, glenohumeral joint external rotation range of motion were measured. Scapulothoracic joint mobilization was applied and then measurements were taken again to compared the changes. Results: After applying the scapulothoracic joint mobilization, lateral slide scapular test, grip strength, visual analogue scale, glenohumeral joint external rotation range of motion significantly improved. Conclusion: This study found that the scapulothoracic mobilization was effective in improving functional aspects and pain on subject with lateral epicondylalgia. The results suggest that the scapulothoracic joint mobilization is a significant considered intervention method that could be used for subject with lateral epicondylalgia.

Purpose: The purpose of this study was to examine the effects of a progressive exercise program for osteoarthritis patients. Methods: This study was performed from 24th March. to 7th July. 2009. Thirty six osteoarthritis patients were participated in the progressive exercise program. Outcome measures were shoulder flexibility, knee flexibility, grip strength, pain intensity, number of pain site and fatigue. SPSS/WIN Version 14.0 was used for the data analysis. Results: At the completion of 6 weeks of progressive exercise program, there were statistically significant differences in shoulder flexibility and knee flexibility. But no significant differences were found in grip strength, pain, number of pain site and fatigue between pretest and posttest. Conclusion: Progressive exercise program was proved to be an effective nursing intervention for improving the shoulder and knee flexibility. However, progressive exercise program did not increase pain & fatigue.

The purpose of this study was to investigate difference between grip strength, upper limb dexterity, and hand function according to touch and heat sensory stimulus. Forty healthy men were recruited. After obtaining subjects characteristics, examined grip strength, upper limb dexterity, and hand function, then we made touch sensory input using soft brush and tried the test again. Next day, we made thermal input using hot pack and did retest, too. The result showed significant differences appeared on every variable in grip strength and upper limb dexterity test (p<.001), and significant differences appeared on every variable except lifting small objects in hand function (p<.01). In conclusion, sensory input is to increase grip strength, upper limb dexterity, and hand function. The thermal sensory input has a tendency to increase grip strength, upper limb dexterity, and hand function than that of touch sensory input in effect of stimulus classification. The application of proper stimulus helps to facilitate upper limb and hand function in rehabilitation and in industrial field. So it is necessary to try more tests of frequency and intensity of stimulus.

This study aims to investigate the interdependence of Korean middle and old-aged couples in the association between exercise and life satisfaction through grip strength trajectory. Data were drawn from the nationally representative Korea Longitudinal Study of Aging (KLoSA) collected from 2006 to 2016. The sample included couples over 45 years of age in the first wave and participated in all six waves of the survey (Ncouple=1,997). There were three steps for analyses: correlation, parallel latent growth curve model, tests of indirect effects of the mediation paths. Covariates included in the models were husbands and wives' characteristics (age, education, work status, chronic diseases, marital satisfaction, contact frequency with friends or neighbors) and couple's household income. Results showed husbands' and wives' life satisfaction and grip strength were interdependent upon each other. Also, exercise participation of both husbands and wives was associated with both husbands' and wives' life satisfaction via the initial level of grip strength of husbands. Moreover, exercise participation of only husbands was associated with wives' life satisfaction through the initial grip strength of husbands. These results suggest the aging processes of middle and old-aged couples need to be understood in the context of gender dynamics and couple interdependence.

Human physical activity to lead daily life is performed by a variety of muscular activity strategies. These strategies can be influenced by characteristics, difficulty and muscle fatigue of work. Therefore this study examines muscular strengths (grip and back strength) of workers engaged in electronics industry in Korea, compares them to mean value of muscular strength by sex and age, accumulates related data and then aims to develop improvement methods of working environment and prevention/management program.

This paper presents the grip force control of myoelectric hand prosthesis according to myoelectric signal generated in the human muscle. The control system consist of a controller for driving DC motor, torque sensor for measuring out torque of motor, slip sensor for detecting slip of torque. The experimental results proved the reliability of proposed control system.

Objective: Previously, we reported quantitative trait loci (QTLs) affecting backfat thickness (BFT) traits on pig chromosome 5 (SW1482-SW963) in an F2 intercross population between Landrace and Korean native pigs. The aim of this study was to evaluate glutamate receptor-interacting protein 1 (GRIP1) as a positional candidate gene underlying the QTL affecting BFT traits. Methods: Genotype and phenotype analyses were performed using the 1,105 $F_2$ progeny. A mixed-effect linear model was used to access association between these single nucleotide polymorphism (SNP) markers and the BFT traits in the $F_2$ intercross population. Results: Highly significant associations of two informative SNPs (c.2442 T>C, c.3316 C>G [R1106G]) in GRIP1 with BFT traits were detected. In addition, the two SNPs were used to construct haplotypes that were also highly associated with the BFT traits. Conclusion: The SNPs and haplotypes of the GRIP1 gene determined in this study can contribute to understand the genetic structure of BFT traits in pigs.

As an advance in medical technology development is being made, and people are increasingly aware of the importance of health, related investments and people's average life expectancy rise, which in turn leads to an increase in elderly people. Also, with a growing number of elderly people enjoying their leisure activities, the utilization of multimedia contents using computers is on the increase, leading to an activated research into the establishment of digital culture for the elderly people. This paper proposes a Korean text input system to enable the elderly to utilize digital contents. Text input interface has conventionally depended on keyboards. However, the keyboard wherein many keys are dispersed creates problems for the elderly, such as a protracted recognition of keys and a lowered concentration when they use the keyboard. To address these problems, in this paper, the grip type controller interface for console games was used and a corresponding alphabet location algorithm was developed. To verify these efforts, a simulator was developed to test 20 elderly people; as a result, their satisfaction over and convenience of using the grip type interface increased.
