Objective: This study was to investigate the effects of coordinated upper-limb body postures on the subjective discomfort rating, heart rate, and muscle activities. Background: Although generally many checklists such as OWAS, RULA, and REBA were applied to evaluate various body postures, the body postures were might be overestimated or underestimated because each body part(i.e., back, shoulder, and elbow etc.) was evaluated separately, and then added all rates of individual body parts to assess an overall risk level for the body posture in these methodologies. Methods: A total of 20 participants maintained 14 postures which were combinations of back, shoulder, and elbow flexion angles and then muscle activities, subjective discomfort, and heart rates were collected every three minute during a sustained 15 minute and 0.5kg weight holding task. Four muscle groups were investigated: erector spine, anterior deltoid, upper trapezius, triceps brachii. Results: Results showed that subjective discomfort was the lowest when the angle of back and shoulder were both $0^{\circ}s$, while the body posture with $45^{\circ}$ of back angle and $45^{\circ}$ shoulder angle was rated as the most subjective discomfort posture. In general, the subjective discomfort ratings increased as back and shoulder flexion angles increased. It was noted that, however, the subjective discomfort of body posture with a $45^{\circ}$ back angle and $45^{\circ}$ shoulder flexion angle was lower than that of body posture with a $0^{\circ}$ back and $45^{\circ}$ shoulder flexion angle. The research findings of heart rates and muscle activities showed similar results for the analyses of subjective discomfort ratings. Conclusions: The possible limitations of the current ergonomics evaluation techniques which assessing a body posture with summing all body part score after individually analyzed in this study. Based on the analyses of subjective discomfort, heart rate, and muscle activities, it was recommended that a use of effects of coordinated upper-limb body postures would be considered when one evaluates work-load for various working postures. Application: These findings can be used for developing a more accurate assessment checklist for working posture as well as preventing musculoskeletal disorders of workers in workplaces.

The purpose of this study was to study real body size and ideal body shape by consoidering the degree of satisfaction at body part and understanding body size by the degree of leanness/obesity. The subjects in this study were 201 female college students aged from 18 to 26. Boby measurements and survey were taken from May to June, 1991 and 1992. Data were analyzed by correlation analysis, regression analysis, cluster analysis, ANOVA, discriminant analysis and crosstabulation analysis. The results were as follows ; 1. The subjects tended to be satisfied with long and slim limbs, slim trunk, and prefered to be tall in height and light in weight. Also the consciousness about thickness was keener than that about length of the body. 2. The subjects were conscious that lower body was more obese than and upper body. Also, the consciousness of whole body had higher correlation with that of upper body than lower body. 3. The subjects were classified into 4 clusters each consisting 23, 87. 68, 23 by cluster analysis of 21 variables after a transformation of measurements to eliminate body size factor. This classification was considered to express how lean or how obese a human body appears. 4. According to the degree of leanness/obesity from lean tendency group I to obese tendency group IV, characteristics of the body shape were changed as follows ; height lower, limbs shorter, trunk and limbs thicker and weight heavier. 5. The subjects of lean tendency group I were more satisfied with their body than those of obese tendency group IV. 6. The subjects, although they were not judged to be obese by somatometric measurements, felt themselves obese. Also, they hoped to be slimmer at lower body than upper body.

The purpose of this research is to compare the body proportion of the Mongolian and Korean men and women in their 20' s by comparing the characteristics of the body type that uses the body indexes, in order to provide the base data for the increased fit of the apparels. The results are as follows. 1) Histogram of the Rohrer' s Index for the Mongolian men and women in their 20s was examined. the Mongolian men, normal body type took up 48.0% while small body type comprised 50.0% and obese body type comprised 2.0%. the Mongolian women, normal body type comprised 61.5%, small body type comprised 22.1% and obese body type comprised 16.4%. 2) The body proportion of Korean men has 1:1.62 with upper body and low body part on a waist basis, and Mongolian men has 1:1.65. Thus Mongolian men has longer pan of lower body than Korean men. 3) Mongolian women has longer part of lower body and has higher rates of hip height, crotch height, knee height than Korean women. Mongolian women has high rate of hip line and calf length. 4) As a result comparison using the body index of Mongolian and Korean women (bust thickness/ bust width, waist thickness / waist width, hip thickness / hip width, when regarding the height as 100 ), it was found that Mongolian women are flatter than korean women.

The purpose of this study is to study real body size and ideal body shape by considering the degree of satisfaction of body part and understanding body size by the degree of leanness/obesity. The subjects in this study were 420 males from 18 to 25 years old. Body measurements and surveys were taken and analyzed by mean, standard variation, correlation analysis, regression analysis, crosstabulation analysis, cluster analysis, one-way ANOVA, and Duncan's Test. The results of analyses indicate that the subjects tended to be satisfied with thick chest and upper limbs, wide shoulder width, and preferred to be tall and have big hands and feet. By cluster analysis of 19 variables, the subjects were divided into 4 groups, each consisting 41, 138, 134, and 47 males. Because the 19 variables were body measurements transformed to eliminate the body size factor, this classification was considered to express how lean or how obese a human body appears. The results of one way ANOVA and Duncan's Test indicate that, according to the degree of leanness/obesity from Group I (lean tendency) to Group IV(obese tendency), characteristics of the body shape changed as follows; height became lower, limbs became shorter, trunk and limbs became thicker and weight became heavier. Also it showed that Group IV were most satisfied with chest girth, upper limb girth and shoulder width and Group I with height, hip girth and waist girth.

Eighty one specimens of nhodeus sericeus (Pallas, 1176) were collected at the upper stream of the Som River (37$^{\circ}$32' 38" N, 127$^{\circ}$58' 57" E: Maegok-ri, Konggun-myon, Hoengsong-gun, Kanguvon-do, Korea) which is a tributary of the Namhan River. This is the first report of the species in the southern part of the Korean Peninsula. This species is well discriminated from the other species in the genus nhodeus by the following respects. The number of scales of transverse series is more than 34 (range 34-37, mean 35.7 $\pm$0.7). Head is echo감or and snout is Bonder than those of the other species. The upper part of the eve is always black and the lateral body surfaces are reddish purple. It had been hem that the southern limit of the distribution of Rhodeus sericeus was the Yonghung River in Hamgvongnam-do, north-eastern part of the Korean Peninsula. But their distributional range is extended more southerly to the Han River system which tons westward through the central part of the Korean Peninsula.Peninsula.

In this research, I classified adult women's back types through anthropometric measurement and photographic measurement to present a judging individual body size according to the type. Also, Ⅰ calculated regression fomula by types and presented the basic bodice pattern. The results were as follows: 1. The result of factor analysis indicated that 5 factors were extracted and those factors comprised 75.89% of total variance. 2. According to the cluster analysis, Ⅰclassified the back types into 6 types. Type 1 was passive posture in the upper and the lower parts of the back. Type 2 was active posture in the upper and the lower parts of the back. Type 3 had the lowest protrusion of the back. Type 4 had the upper part of the back which is mostly bent downward. Type 5 was the most suitable shape. Type 6 had the lower part of the back which was turned over the most. 3. Ⅰconducted a discriminant analysis to judge the body types of individuals. 4. For the calculation of measurements necessary for the basic bodice pattern, Ⅰpresented regression formulas by each type. 5. By conducting the wearing experiments, Ⅰsuccessfully made the final basic bodice patterns by types. As a result of comparative experiments between the basic bodice patterns and comparison bodice pattern, the suitability of basic bodice patterns were more highly assessed.

Lightweight body can cause a low stiffness due to the decrease of panel thickness and reinforcing member. The other way, high stiffness body demands an increase of mass. Front pillar section area is decreased due to driver's visual field. Global vehicle stiffness is affected by stiffness distribution ratio between upper part and lower part at side body structure. This paper will describe a process used to evaluate the stiffness distribution ratio based on research of strain energy analysis of the tip rotation method. In addition, optimum design schemes are presented for high stiffness and lightweight body structure considering the investigated stiffness distribution ratio. In this way the designer will be aided by a defined design guide and a set of supporting tool to help him work towards a good design
