Among various manual materials handling tasks, pushing/pulling was known to be one of the risk factors for the low back and shoulder musculoskeletal disorders (MSDs). This study was conducted to find out an optimal solution set of the handle height and distance for 4-wheel cart with two vertical handles. Ten male college students participated in the pushing force measurement experiment. The face-centered cube design, one of the central composite designs, was applied for the experiment, and the isometric voluntary pushing force was measured in 9 treatment conditions. The second order response surface model was predicted by using the pushing strength as a response variable, and the handle height and distance as independent factors. According to the 2nd order response model, the handle height and distance showed nonlinear relationship with the isometric pushing strength. To maximize the 2nd order response model (pushing force), the handle height and distance were optimized. The optimal handle height was 'xyphoid process height - stature', and the optimal handle distance was '$1.25{\times}shoulder$ width'. When calculated using the anthropometric data of the subjects of this study, the optimal handle height was $115.4{\pm}3.4$ cm, slightly higher than the elbow height, and the handle distance was $52.9{\pm}2.3$ cm.

Kniest syndrome (OMIM #156550) is a rare autosomal dominant disorder caused by a dysfunction of type II collagen, which is encoded by the COL2A1 gene (OMIM +120140) mapped to chromosome 12q13.11. Type II collagen, a molecule found mostly in the cartilage and vitreous tissues, is essential for the normal development of bones and other connective tissues. Kniest syndrome is a type II collagenopathy that presents as skeletal abnormality associated with disproportionate dwarfism, kyphoscoliosis, enlarged joints, visual loss, hearing loss, and cleft palate. This report describes a Korean patient with Kniest syndrome who was diagnosed with typical clinical features and radiologic findings. The patient presented with disproportionately short stature and kyphoscoliosis from birth. A skeletal survey revealed fused lamina in the thoracic spine, hemivertebrae, flexion deformities in multiple joints, and plagiocephaly.

For the purpose of carrying out nutrition counseling effectively and efficiently, this study assessed the nutrition counseling practice, perception and nutrition knowledge of elementary school children in Gyeongbuk province. Survey questionnaires were distributed between November 2009 and December 2009 to 100 nutrition counseling experienced children (participants) and 110 nutrition counseling non-experienced children (non-participants) and were completed with nutrition teachers' assistance. According to the survey results, girls and overweight/obese children showed higher tendency of participation in nutrition counseling (p<0.001). Participants who took nutrition counseling according to their own intentions showed satisfaction after counseling on diverse subjects such as obesity, unbalanced diet, and weight control. Particularly, 'lack of counseling session time', 'unfavorable counseling condition' or 'difficult explanation' caused participants unsatisfaction after counseling. Participants usually perceived the meaning of nutrition counseling more correctly than non-participants and showed positive intentions for taking further counseling in the future(p<0.001). Diet good for weight control, good food to fix unbalanced diet and diet good for growing stature were the top three subjects of nutrition counseling chosen by subjects (p<0.001). Participants also showed higher nutrition knowledge scores than non-participants. Therefore, it is critically important to apply nutrition counseling in the proper environment (counseling room, time, teaching materials, etc) to elementary school students to fix healthy food habits. Therefore, nutrition teachers need to be provide professional nutrition counseling skills and knowledge.

The purpose of this study is to measure a perceived joint discomfort in the seated and standing position, and to provide ranking systems of perceived joint discomfort. Nineteen mole subjects with no history of musculo-skeletal disorders participated in the experiment. Their physical characteristics were: age $-25.4{\pm}2.7$years, stature $-171.9{\pm}6.0cm$, and body weight $-67.1{\pm}7.0kg$. The results showed that the perceived joint discomforts were different depending upon the joints involved in motion and their movement directions (degree of freedom of motions), which implied that the human body motions and their degrees of freedom should be classified into several distinct classes that need to be assigned different weights of postural stress. Therefore, three ranking systems based on the perceived joint discomforts were suggested, which were classified by the degree of freedom of motions and joints, by only degree of freedom motions, and by joints involved in motion, respectively. In the seated position, the hip movement was the most stressful, the bock was the second, and the shoulder was the third. Likewise, in the standing postures, the hip was the most, the bock was the second, and the ankle was the third. It was expected that these joint motion ranking systems could be used by practitioners of health and safety to improve the comfort of working postures in industry.

North Korea has been experiencing a serious food shortage. However, the extent and magnitude of malnutrition and health problems are virturally unknown because a nationwide food and nutritional survey has never been conducted. To get a better udnerstanding of the situation., an exhaustive literature search on the health and nutritiona conditions of North Koreans was performed. We also obtained anthropometric data on 274 North Korean Defectors who are recently resettlers in the South. Some(137) measurements were taken at the time of entry to the South, and the remaining data was from the health and nutrition mail survey conducted by us on North Korean refugeee re-settlers. Health and inutritional status of North Koreans was found to be less than desirable as shown in high infant mortality rates, high mortality and morbidity rates of malnutriton-related infectious deseases, and smaller body sizes. Striking differences were noted in all of the above health and nutrition indicators between north and South Koreans. Considering the fact that North and South Koreans are homogeneous in their genetic back-ground, ours study results clearly demonstrate that the health and nutrition of North Koreas has deteriorated with the dhronic food shortage, which might have sorsened with a recent food crissi. The smaller and thinner adult stature proevailing in North Korea could play a significant negative role in the country's economy, since lower lean body mass has been associated with reduced work productivity that could hinder economic growth and development.

This study examines the characteristics of fat body type males aged 35 to 55 with a BMI rate higher than 25 categorized as mid-degree obesity and high-degree obesity according to the $6^{th}$ Size Korea; in addition, the study provides a sizing system for obese males. The physical characteristics of the obese male appeared to be with a shorter lower body compared to an upper body for a higher degree of obesity. Obesity appeared evenly from chest to thigh circumference compared to a normal group. Especially, their waist measurement, depth, and width were significantly larger as well as the crotch length (natural indentation) and a larger waist measurement. As for the cloth sizing system, this study suggests the sizes with higher distribution among the designated size intervals of casual tops, men's suit tops and bottoms based on standard stature, chest size and waist circumference (Omphalion) by KS.
