Objectives. This study was conducted to evaluate the association between upper extremity musculoskeletal symptoms and Rapid Upper Limb Assessment(RULA) in vehicle assembly line workers. The goal of this study is to show the feasibility of RULA as a checklist for work related musculoskeletal symptoms (WMSDs) in Korean workers. Methods. The total number of 199 people from the department of assembly and 115 people from the department of Quality Control(QC) in automotive plant were subjects for this cross sectional study. A standard symptom questionnaire survey has been used for the individual characteristics, work history, musculosketal symptoms and non-occupational covariates. The data were obtained by applying one-on-one interview for the all subjects. RULA has been applied for ergonomic work posture analysis and the primary ergonomic risk sure was computed by RULA method. Association between upper extremity musculoskeletal symptoms and RULA were assessed by multiple logistic regression analysis. Results. A total of 314 workers was examined. The prevalence of musculoskeletal symptoms by NIOSH case definition was 62.4%. The distribution of musculoskeletal symptoms by the part of the body turned out to be following; back:41.4%, neck: 32.8%, shoulder: 26.4%, arm: 10.5% and hand:29.3%. The relationship of the individual RULA scores were statistically significant for the prevalence of musculoskeletal symptoms. As the result of the multiple logistic regressioin analysis, grand final score (OR=2.250 95% CI: 1.402-3.612) was associated with musculoskeletal symptoms in any part of the body.; upper arm score(OR=1.786 95% CI: 1.036-3.079) and posture score A(OR=1.634 95% CI: 1.016-2.626) in neck; muscel use score(OR=3.076 95% CI:1.782-5.310) and posture score A(OR=1.798 95% CI: 1.072-3.017) in shoulder; upper arm score(OR=1.715 95% CI: 1.083-2.715) and muscel use score(OR=2.057 95% CI:1.303-3.248) in neck & shoulder; muscle use score(OR=10.662 95% CI: 3.180-35.742) in arm; writst/wist score(OR=2.068 95% CI: 1.130-3.786) and muscle use score(OR=2.215 95% CI: 1.284-3.819) in hand & wrist.; muscle use score of trunk (OR=2.601 95% CI: 1.147-5.901) in back. Conclusions. Musculoskeletal symptoms of the extremities were strongly associated with individual RULA body score. These results show that RULA can be used as a useful assessment tool for the evaluation of musculoskeletal loading which is known to contribute to work-related musculoskeletal disorders. RULA also can be used as a screening tool or incorporated into a wider ergonomic assessment of epidemiological, physical, mental, environmental and organizational factors. As shown in this study, complement of the analysis system for the other risk factors and characterizing between the upper limb and back part will be needed for future work.

Thyroid hormones are essential for cellular energy homeostasis and regulation by interacting with the sympathetic nervous system. This study was conducted to investigate the relationship between thyroid hormone and risk factors of metabolic syndrome for medical checkups of male patients. The study subjects were 12,250 males between 20~80 years old who visited the hospital for a health check-up at one General Hospital in Gyeonggi-do during the period of January 2011 to December 2013. According to the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI), the metabolic syndrome criteria is defined as the presence of 3 or more risk factors. FT4 was lower in the metabolic syndrome group than in the normal group (p<0.001). The level of FT4 decreased as the levels of abdominal obesity (p=0.001), hypertriglyceridemia (p<0.001), blood pressure (p=0.005) and blood glucose (p=0.005) increased. The TSH level increased hypertriglyceridemia (p=0.047). FT4 had an influence on the waist circumference and triglyceride (p<0.001). HbA1c, insulin, HOMA-IR, hs-CRP were higher in the lowest quartile than in the highest quartile (p<0.001). FT4 had effects on the waist circumference and triglyceride, but TSH had no effect on metabolic syndrome risk factors. The metabolic syndrome was lower in the highest quartile of FT4 than in its lowest quartile.

Objectives: This study was performed to examine the healthy lifestyle influenced on the metabolic syndrome among the elderly in the rural area. We examined the changes of risk factors of metabolic syndrome after two years. Method: Out of 134 who did health screening at the J county health center from July 1 to August 31, 2006, 65 aged people confirmed to metabolism syndrome were selected as subjects. For the final analysis, 62 aged people who revisited after two years were selected our subjects. The data were analyzed using SPSS PC+ 12.0 program for descriptive, Chi-square test, t-test and ANOVA analysis. Result: The result of this study indicated that 62 metabolic syndrome patients in 2006 decreased into 53, and women were higher than men. The difference in the metabolic syndrome came from level of education, smoking, health practices, and past illness history. Conclusion: Therefore, the change of lifestyle needs to be induced by the level of education, and for the group of smoking, non-exercise, and past illness history not only regular checkups to prevent metabolic syndrome but also education to have interest on themselves may need intensively.

Objectives: This study aimed to determine the effects on musculoskeletal symptoms of both social demographic features and detailed characteristics of each task category of care workers who offer visiting home-help services. And to establish the measures that can reduce musculoskeletal symptoms among care workers. Methods: This study was conducted among 192 care workers from welfare centers C and K located in city P. After participants completed the task burden checklist regarding the scale of musculoskeletal symptoms and the details of their duties, the data collected were analyzed using the SPSS 21.0 program. Results: According to the degree of observable musculoskeletal symptoms in care workers, the highest figures were observed for back and shoulder pain. Based on the results of assessing the effect of detailed task category characteristics on musculoskeletal symptoms, "helping patients eat, helping patients move, helping patients bath, and changing body positions" were found to have an effect from the physical care category, "providing physical therapy assistance, treating bedsores" from the health care category, and "cleaning and doing laundry" from the facility management category. Conclusions: Due to the high proportion of patients requiring burdensome physical labor from care workers such as moving patients who have trouble doing so on their own, helping them change positions, and so on, it is highly likely that pain will occur in the low back, which carries most of the physical weight. So, education on human epidemiological positions that can reduce overload on areas prone to pain such as the low back and shoulders is essential. Proper equipment and personnel support must be provided for dangerous tasks. Further, multidimensional social support is required consistently.

This study was intended to develop a prototype of new Hanbok Cheollik one-piece based on design extracted through a preference survey on new Hanbok Cheollik one-piece. Through this, it was intended to provide information on patterns that are fundamental to the production of new Hanbok Cheollik one piece. The pattern of the experiment was produced by modifying D pattern, which was selected as excellent in the comparison of commercial Cheollik one-piece patterns. The SPSS 26.0 program was used to analyze the appearance evaluation of patterns. As a result of the 1^st evaluation of appearance and garment pressure, the shoulder, sleeve length, skirt length and sleeve width required modification, reducing the sleeve length by 8.0cm and the sleeve width by 1.0cm in total. The length of the skirt was reduced by 5.0cm and the shoulder end point was reduced by 0.5cm on both sides to modify the shoulder width. As a result of the 2^nd evaluation, the waist area, sleeve width, and skirt wrinkles were required to be corrected, reducing 2.0 cm waist width and 1.0 cm sleeve width and removing wrinkles on the front center and side area. The final pattern was highly appreciated. In future studies, it is thought that research should be conducted through study of Cheollik one-piece pattern according to material and age and the actual wearing experiment according to fabric and age.

Background: It is essential to investigate the functionality of the newly developed knobble shoe. Purpose: The purpose was to explore how the body shape and balance change when wearing knobble shoes. Methods: Nine subjects wearing knobble shoes after walking for a month were analyzed. Results: For knobble shoes, we created various small air pockets in the insole to stimulate the soles of the feet to induce body changes. In particular, it was to promote the arch part of the foot by making a large lump inside and outside the center of the foot's arch. After wearing knobble shoes and using them for 30 days, the average blood sugar decreased by 31.1 mg. The lowering range was 5 to 120 mg. In one patient, the result of the hemoglobin test decreased by 7.5% to 6.5%. In the shoulder tapping test for a body balance test, seven subjects leaned to the right in a barefoot state, and two people to the left. However, after wearing shoes, all of them maintained equilibrium. knobble shoes fit, and balance was all stable. There were two subjects with a short left and four subjects with a short right. Conclusions: Blood sugar decreased after wearing the knobble shoes. The deformed shape of the body was restored to its original state by the knobble supporting the foot arch area. The balance of the sole directly affects the overall posture.
