This study aims to compare a self-reported and expert-observed method on ergonomic risk factors of Work-related Musculoskeletal Disorders (WMSDs). The checklist was developed based on the results of previous studies, and the symptoms of WMSDs were obtained using a self-reported questionnaire from 1,029 shipyard workers. The risk factors were assessed through the self-report by workers and video analysis by ergonomists. The symptom prevalence at the low back (59.2%), shoulders (50.8 %), and knees (49.7%) were relatively higher than those at other body parts. Odds ratios (ORs) by body parts were 2.48 to 2.90 for the risk job, and the ORs were significantly different from those of the low risk job. The risk factor scores by body parts between workers and ergonomist were very high correlation(r=0.82 to 0.92). The rates of self-report from risk job were 54.0% (elbow and arm) to 72.1 % (low back), but sometimes overestimated(105.7 to 122.6%) than those by ergonomists. The checklist, developed in this study, will be an efficient tool for the evaluation of risk jobs using self-report by workers.

Objective : Recently, there is an increasing trend of attachment to physical appearance of individuals in many persons with spread of social concern through mass communication. Domestically, several studies has been performed, but they were limited to obesity mainly for juveniles or female college students. Therefore, purpose of this study were to standardize Body image dysmorphic disorder examination self report with male and female college students in Cheonnan area. Methods : This study were total 825 college students in Cheonan area. Subject group are consist of 393 males (47.6%) and 427 females (51.8%), and the mean age was $22.28{\pm}3.24$ years old. Results : The BDDE-SR had adequate internal consistency (Cronbach's alpha=.93) and test-retest (r=.82) and interator reliability. Four factors were extracted by factor analysis with the Varimax rotation. They were 'the camouflage and comparison factor', 'the self-consciousness and negative self-evaluation factor', 'the avoidance factor', and 'the distressing and embarassment factor'. The total score of BDDE-SR was $50.8{\pm}27.1$, female's score ($59.2{\pm}25.5$) was statistically higher than male's score ($41.85{\pm}25.84$). Conclusion : It is considered that BDDE-SR is reliable instrument for body image dissatisfaction, provided correct information in predicting clinical status of Body dysmorphic disorder that is most largely influenced by individual psychologic factor and family system.

Design of a Pump Jet Propulsor (PJP) was undertaken for an underwater body with axisymmetric configuration using axial/low compressor design techniques supported by Computational Fluid Dynamics (CFD) analysis for performance prediction. Experimental evaluation of the PJP was earned out through experiments in a Wind Tunnel Facility (WTF) using momentum defect principle for propulsive performance prior to proceeding with extensive experimental evaluation in towing tank and cavitation tunnel. Experiments were particularly conducted with respect to Self Propulsion Point (SPP), residual torque and thrust characteristics over a range of vehicle advance ratio in order to ascertain whether sufficient thrust is developed at the design condition with least possible imbalance torque left out due to residual swirl in the slip stream. Pumpjet and body models were developed for the propulsion tests using Aluminum alloy forged material. Tests were conducted from 0 m/s to 30 m/s at four rotational speeds of the PJP. SPP was determined confirming the thrust development capability of PJP. Estimation of residual torque was carried out at SPP corresponding to speeds of 15, 20 and 25 m/s to examine the effectiveness of the stator. Estimation of thrust and residual torque was also carried out at wind speeds 0 and 6 m/s for PJP RPMs corresponding to self propulsion tests to study the propulsion characteristics during the launch of the vehicle m water where advance ratios are close to Zero. These results are essential to assess the thrust performance at very low advance ratios to accelerate the body and to control the body during initial stages. This technique has turned out to be very useful and economical method for quick assessment of overall performance of the propulsor and generation of exhaustive fluid dynamic data to validate CFD techniques employed.

To compare actual obesity rate and self-evaluated body shape, 651 women living in Inchon were participated in the measurement of anthropometric indices and in the survey by questionnaire. Mean RBW and BMI were in normal range except the girl in 13-15 years. RBW and BMI of the women in 40s and 50s were significantly higher than those in women in younger ages(p<0.001). Triceps skinfold thickness of the subjects were not significantly different. Significantly low DRBW in teenagers and women in 20s showed that their desire to reduce body weight were very strong. Over the half of the subjects thought they were too heavy and unsatisfied at their body shapes. The parts of the body desired to remove extra fat were the waist & abdomen in women over 30s and the thigh & legs in teenagers. It is thought that women, especially in 10s and 20s need the education about the appropriate evaluation of body shape and also need the nutrition education about the deteriorated influence of underweight on health.

This Quantitative study was investigated to examine the relationship between self-esteem on body image and disordered eating patterns in some university students. This study used a cross-sectional study design. Total 347 students participated in this study (88 male and 259 female) among three universities. The assessment of eating disorder was conducted by Eating Attitudes Test (EAT-26), a score of >or=20 identified individuals likely have an eating disorder, including anorexia nervosa and bulimia nervosa. Ideal body weight and current body weight were completed with self-evaluation. A distorted body image was independently related to the eating problem in the Logistic regression analysis. There were stronger relationships between their EAT-26 scores and their expected weight changes and weight control behaviors. Compared with the men, women showed highly wishful to loss for current body weight. In the relationship between score of EAT-26 and BMI distance by sex, levels of eating disorder showed linearly elevated toward increased BMI distance (Ideal BMI-Current BMI) (F-value=18.794, p<0.0001) in women, but there were not significant in men (F-value=2.028, p>0.05). In estimate on state-trait anxiety inventory according to quartile of BMI distance by sex, levels of state-trait anxiety were not significant difference by degree of body dissatisfaction in all sex. In addition, higher distorted body image was significantly increased numbers of weight control method and experience of side effects in female, but there were not showed significant relation between two variables in male.

The purpose of the study was to identify the motives of women's appearance-management behavior, and examine how women perceived the appearance -management behavior and pursuit of ideal body image. The depth interview method was managed to five female subjects who had experiences in plastic surgery and obesity treatment. The instance analysis used in this study. The results were as follows : There were four types of women's appearance-management behavior. First, women perceived themselves by using other people's evaluation, and it was the first motive of appearance-management behavior. It shows that appearance is not based on the real self-image but is the evaluated self-image by others. Second, women were willing to suffer the pain in the plastic surgery and obesity treatment by the expectation of appearance improvement. It means the result of reducing the difference between the actual self-figure and the ideal self-image. Third, the sexual discrimination culture had an influence on appearance-management behavior. It seems the sense of male superiority spreaded over the Korean society. Lastly, women improved self-satisfaction and self-esteem through their physical appearance as an alternative method for better life.
