Domestic sewing industry is showing signs of a redevelopment and the demands of the sewing technician are gradually increasing. This study would investigate the opinions of sewing technicians about job environments and training situation in order to solve the shortage of sewing manpower. As a result of a survey with 100 sewing technicians, of the pay systems, the salary system showed the highest satisfaction and preference. Their satisfaction with pay was low. There was a tendency that they work on Saturdays and national holidays, and their satisfaction with the number of holidays was low. Most worked for 10 to 11 hours per day, and they showed low satisfaction with their working hours. There were no places to rest in the company. They showed law satisfaction with the air and vent. The sewing technicians were concerned about respiratory and musculoskeletal diseases because of the working and workplace environment and needed places to rest, vent facilities, and spacious and comfortable spaces. The total lead-time that they were sent to the field as skilled workers was 1 to less than 2 years; they received training from seniors; and the training period, mostly, was 6 months to 2 years. Most of the sewing technicians surveyed had the expertise, did not feel the necessity of retraining related to their tasks, and did not have any willingness to take reorientation due to a lack of time even with their tasks.
Background : With the increase of cooperative practices (CP) between conventional western medicine and traditional Korean medicine, there have been lots of researches on the status of CP and the attitude of doctors. Objective : Since most of the research is cross-sectional, this study aims to figure out the changes in the attitude of doctors toward CP through systematic review. Method : Systematic literature searches were performed on several databases in Korea. They were categorized according to the respondents and question items and analyzed by the context of questions, similarity of respondents and measurement scale. And we analyzed the changes of response regarding to doctors' awareness and attitude to CP. Results : Thirteen survey studies including attitude of doctors toward CP were selected. These studies were conducted between 1997 and 2009 and the number of respondents of each study ranged from 20 to 702. There has been increasing awareness of CP among doctors ; however the positive responses on the necessity of CP has decreased. Regarding the type of illness effectively treated employing CP, there was a shift from neurovascular to musculoskeletal and immune diseases. Most of the studies listed different approaches to disease, prejudice of health care providers and inadequate legal system as major obstacles against CP. Conclusion : In spite of the increase of CP in the last 20 years, there has not been marked positive change in the doctors' attitude toward CP. To promote CP, it is required to confirm the effectiveness of CP through disease models and change the medical legislation policies on CP.

Background: Patellofemoral pain is one of the common diseases of the musculoskeletal system. Many previous studies have recommended the application of exercise therapy to patellofemoral pain patients for treatment. The purpose of this study was to investigate effect of coordinative locomotor training (CLT) and sling exercise combined program on knee pain and functional movement in patellofemoral pain patient. Methods: In this study, single-subject design (A-B-A') was conducted for 6 weeks. A repeted-measure analysis was conducted to assess results of the anterior knee pain scale (AKPS), Clarke's test (CT), eccentric step down test (ESDT). During the intervention (B), the CLT and sling exercise combined program was conducted three times a week for 4 weeks. Results: From baseline period A to intervention period B, the AKPS, CT, ESDT were improved from 61 to 48 (27%), from 8.33 to 3 (64%), from 7.67 to 3,58 (53%). From baseline period A to baseline period A', the AKPS, CT, ESDT were improved from 70.67 to 48 (47%), from 0.67 to 3 (92%), from 1.33 to 3,58 (83%). Conclusion: Based on the results of this study, we recommend the application of CLT and sling exercise combined program to improve the pain and functional movement in patellofemoral pain patients.
Objectives: The purpose of the study is to investigate the musculo-skeletal pain prevalence and severity in the dental hygienists based on PRECEDE model. Methods: A self-reported questionnaire was completed by 483 dental hygienists in Gwangju from September 13 to October 12, 2013. Data were analyzed by frequency analysis, chi-square test, t-test, and multiple logistic regression analysis using SPSS 18.0 program. Musculo-skeletal pain severity was classified from 1 to 5 by PRECEDE model. The questionnaire consisted of six questions of the general characteristics of the subjects, one question of musculo-skeletal pain prevalence, one question of body part musculo-skeletal pain prevalence, one question of subjective health status, three questions of activities of daily living, six questions of working environment, one question of musculoskeletal system diseases knowledge, two questions of social support, two questions of education experience and data use method, and five questions of necessity of health education. Results: The prevalence rate of musculo-skeletal pain within a year was 83.9% and 22.8% of the dental hygienists complained of severe pain. The odds ratio of moderate pain severity was 1.99(95% CI, 1.10-3.60) and the odds ratio of unhealthiness was 3.27 (95% CI, 1.35-7.94). The odds ratio of pain severity in those working for 4-6 years was 0.21(95% CI, 0.08-0.57). The odds ratio of pain severity in those practicing 6-10 scaling cases per day was 0.33(95% CI, 0.17-0.65). The odds ratio of pain severity in wrist turning and bending was 3.56(95% CI, 1.19-10.62). Conclusions: The muscolu-skeletal pain severity in the dental hygienists was closely associated with subjective health condition, work duration, the number of scaling practice activity, and a treatment posture. Regular physical checkup for the dental hygienists will improve the musculo-skeletal pain due to scaling practice.

PURPOSE: Application of an oscillating program for the lower extremities is an effective training method for increasing muscle strength. However, no oscillatory program has yet been identified to confirm the effectiveness of oscillation for balance ability and maximum muscle strength. We investigated the effects of an 8-week vibration exercise program on the maximum muscle strength and balance of the lower extremities. METHODS: Research subjects participating in the study were 22 male and female college students with no past history of diseases of the nervous or musculoskeletal systems. All subjects were randomly divided into two groups and performed their assigned experimental treatment 3 times a week over a period of 20 min for 8 weeks. Maximum strength of the quadriceps extension, flexion, and balance ability were measured using Biodex System 4 and Biodex balance systems. RESULTS: The 8-week oscillation program resulted in a significant increase in quadriceps extension and flexion strength in both male and female participants (p<.05). The balance ability also showed a significant improvement after the oscillation program (p<.05). The balance value was higher for male 17% than for female 21% (p<.05) participants. CONCLUSION: An 8-week oscillation program led to an increase in the strength of knee flexion and extension. The balance ability also improved significantly. This positive effect on balance ability was higher in female than in male subjects.
Purpose: The purpose of the study is to investigate health problems of migrant workers in Korea. Methods: The data were collected from the records of the medical history of 2,233 migrant workers who visited the community health clinic in Ansan city, Gyeonggi province from Jan. 2005 to Jan. 2007. The data were analyzed by SPSS. Results: Men accounted for 56.4% of the total who participated in the study. Most of them were Chinese, Russian, and Bangladesh people. The 590 people out of all the migrant workers were employed in manufacturing industries and they comprised the largest percentage. The most commonly complained health problems were musculoskeletal (31.7%), digestive (20.7%), respiratory (12.5%), dermatologic (6.5%), cardiovascular (5.5%) and dental disorder (5.2%). The 1,853 (36.0%) workers were assumed to have hypertensive disorder and 1310 (11.1%) workers, some diseases due to high cholesterol level. Conclusions: It is necessary to establish a public health care system to improve health and welfare of migrant workers. Furthermore, the communities need to draw their attention to this matter. And it is also necessary to make accurate research on their health and medical service.

Background: Previous research has shown that paramedics are exposed to risks in the form of injuries to the musculoskeletal system. In addition, there are studies showing that they are also at increased risk of cardiovascular disease, cancer, and psychiatric diseases, which can partly be explained by their constant exposure to stress. The aim of this study is to evaluate whether the use of shoulder straps decreases physical effort in the form of decreased heart rate and cortisol concentration. Methods: A stretcher with a dummy was carried by 20 participants for 400 m on two occasions, one with and one without the shoulder straps. Heart rate was monitored continuously and cortisol samples were taken at intervals of 0 minutes, 15 minutes, 30 minutes, 45 minutes, and 60 minutes. Each participant was her or his own control. Results: A significant decrease in heart rate and cortisol concentration was seen when shoulder straps were used. The median values for men (with shoulder straps) at 0 minutes was 78 bpm/21.1 nmol/L (heart rate/cortisol concentration), at 15 minutes was 85 bpm/16.9 nmol/L, and at 60 minutes was 76 bpm/15.7 nmol/L; for men without shoulder straps, these values were 78 bpm/21.9 nmol/L, 93 bpm/21.9 nmol/L, and 73 bpm/20.5 nmol/L. For women, the values were 85 bpm/23.3 nmol/L, 92 bpm/20.8 nmol/L, and 70 bpm/18.4 nmol/L and 84 bpm/32.4 nmol/L, 100 bpm/32.5 nmol/L, and 75 bpm/25.2 nmol/L, respectively. Conclusion: The use of shoulder straps decreases measurable physical stress and should therefore be implemented when heavy equipment or a stretcher needs to be carried. An easy way to ensure that staff use these or similar lifting aids is to provide them with personalized, well-adapted shoulder straps. Another better option would be to routinely sewn these straps into the staff's personal alarm jackets so they are always in place and ready to be used.

Objective: To compare the postural control between non-specific chronic low back pain (NSCLBP) subgroups and healthy people during dynamic balance performance using a modified Star Excursion Balance Test (mSEBT). Design: Cross-sectional study. Methods: Eighteen NSCLBP subjects (9 active extension pattern [AEP], 9 flexion pattern [FP]), and 10 healthy controls were enrolled in this study. All subjects performed mSEBT on their dominant leg on a force plate. Normalized reach distance and balance parameters, including the center of pressure (COP) displacement and velocity, were recorded. Results: There were significant differences in mean reach distances in both posterolateral and posteromedial (PM) reach directions between AEP and healthy subjects (p<0.001) and between FP and healthy subjects (p<0.001). However, there were no significant differences among the three groups in the anterior reach direction. Also, the results showed no significant differences in mean COP variables (velocity and displacement) between pooled NSCLBP and healthy subjects. However, the subjects were reclassified into AEP, FP and healthy groups and the results showed a significant difference in mean COP velocity in the PM direction between AEP and FP subjects (p=0.048), and between AEP and healthy subjects (p=0.024). Conclusions: The findings in this study highlight the heterogeneity of the individuals with NSCLBP and the importance of identifying the homogenous subgroups. Individuals with AEP and FP experience deficits in dynamic postural control compared to healthy controls. In addition, the findings of this study support the concept of the Multidimensional Classification System.

Purpose: This study analyzed the muscle activity changes induced by motions of reaching forward and chest expansion that were examined from the bilateral muscles with rectus abdominis, external oblique, multifidus, and longissimus thoracic using Pilates cadillac instrument. Methods: Nine young adult women, who have no musculoskeletal disorder and any of chronic diseases, were participated. Surface electromyography system was used for recording of all signals produced by muscles, and then normalized as percentage of maximum voluntary isometric contraction (%MVIC). The paired t-test and repeated measures of analysis of variance was performed. Results: Reaching-forward motion showed a higher muscle activity from non-dominant external oblique muscle than that of the chest-expansion motion. During both reaching-forward motion and chest-expansion motion, MVIC values collected from dominant side of external oblique muscle were shown a significantly lower than the values obtained from non-dominant side (p<0.05). Conversely, %MVIC values in external oblique muscle collected from dominant side showed a significantly higher than the values obtained from non-dominant side of the same oblique muscle (p<0.05). Reaching-forward motion was caused a higher %MVIC on non-dominant external oblique muscle than that of the chest-expansion motion (p<0.05). Regardless of dominant or non-dominant sides, external oblique muscle was shown the highest activation rate of all the other muscles during reaching forward action, and longissimus thoracic muscle was shown the highest activation rate of all the other muscles during chest expansion action. Conclusion: Reaching-forward motion is suitable for activating an external oblique muscle, and chest-expansion motion is an effective enough in activating of longissimus thoracic muscle.
