Recently, Fishermen have required to expand the circumference of trap entrance for conger eel because it was difficult to take the catch out as well as to put the baits into. A series of fishing experiments was carried out in coastal areas of Tongyoung, Korea in 2008 and 2009 using the traps to describe the effect of the entrance size on the catch. The experimental traps (five types) were used in filed experiments with four types circumference size traps (140, 180, 220 and 260mm) with mesh size 22mm and another type was used the same one usually using in filed with mesh size 35mm (750mm circumference). The experiment results were, the conger eels of total length 35mm more or so were caught 85, 93, 142 and 176 individual by the experiment traps with mesh size 22mm as increase circumference size from 140mm to 260mm, respectively. And the small conger eels of the total length below 35mm to be prohibited to catch by law were caught 145, 160, 288 and 304 individual according to increase the circumference size of trap, respectively. In addition, in case of the trap with mesh size 22mm, bycatches were 230 - 260 individuals and much more than bycatches of the trap with mesh size 35mm. In conclusion, when we expand the circumference size of trap according to fishermen's requirement, we should review not only economic of fishery but also increasement the bycatch of non-target fishes and small size fishes.

The purpose of this study is to measure Korean, Chinese and Chosunjok college women's body part sizes, and then, classify their body shapes according to the drop value(hip circumference-chest circumference) as well as their statures, and thereupon, comparatively analyze the statistical distribution of their major body part measurements and thereby, provide for some basic data useful to the development of quality fitting apparels exportable to China. The results of this study can be summarized as follows; Most of Korean and Chinese college women were found to belong to the body type of "N" body shape, while many of Chosunjok college women belonged to "H" body shape body type characterized by normal stature but small difference between hip and chest circumferences. The most prevailing body type of Korean and Chinese college women next to "N" type(65%, 51%) was "H" (23%, 35%), followed by "A" type(12%, 14%), while that of Chosunjok college women was "H" type (54%), followed by "N" (40%) and "A" type (6%). On the other hand, in terms of distribution of major body part sizes, there was found a wide difference between Chinese and Korean college women. Chosunjok college women had similar body part sizes to Korean college women's in such measurements as waist back length, shoulder-to-shoulder length, front interscye length, back interscye length, under-chest circumference and weight, while having simliar body part sizes to Chinese college women's in such measures as stature, arm length, waist front length, waist side-hip line length, crotch length, head circumference, neck-root circumference and waist circumference.

Objectives : This study aims to confirm the importance of behavior habit and exercise, especially leg exercise in obese. Methods : Out of 2247 people, we divided 1125 people in normal group(BMI<25) and 122 people in obese group($BMI{\geq}25$). We measured each arm, leg, abdomen muscle circumference and right and left water difference using BLA. We Investigated whether ratio of leg muscle circumference to arm and abdomen has differences by statistics between each groups. And analyzed correlation with BMI. We also investigated right and left water distribution difference of two group's limbs and the correlation with BMI. Statistical analysis was performed by using SPSS program. Results : 1. In obese group, ratio of leg muscle circumference to arm and abdomen is significantly lower than normal group(P<0.001). 2. Ratio of leg muscle circumference to arm and abdomen were negatively correlated with BMI(r-0.461, r=0.462, P<0.001). And partial correlation coefficient controlled for age and sex is -0.528, -0.632(P<0.001). 3. In the case of women, there was right and left water distribution difference as statistical in leg. In the case of Obese, the difference is serious. Conclusions : These results suggest that exercise and activity of lower limbs is more needed in the field of obesity treatment and prevention.

Purpose: This study identified the effect of abdominal muscle contraction using changes in waist circumference for healthcare workers with back pain due to inadequate posture during working hours. Methods: In this study, we provided educational training focused on posture alignment and utilized waist circumference change sensors to induce the contraction of abdominal muscles as a method to address low back pain in healthcare workers. All 32 participants received the same training and then were assigned to two groups: wearing the keeping core band (CB) and not wearing the keeping core band (NCB). For the CB group, the waist circumference change sensor was applied for 6 weeks during working hours. Wilcoxon's signed-ranks test and paired t-tests were used to compare the differences between the groups. All statistical significance levels were set to α=0.05. Results: Trunk muscle endurance increased significantly in the CB group. There was no significant difference in stability index to evaluate static postural control, but active hip abduction tests, which evaluate dynamic postural control, showed significant decrease in the CB group. Conclusion: These results suggest that the induction of abdominal contraction using the waist circumference change sensor may improve the trunk muscle endurance and the postural control ability of the hip and pelvis of healthcare workers.

A study using compare and analyze about differences among three basic pants patterns(shape and size of pattern, fitting and amount of air gap and so on) through 3D simulation. This study use 3D simulation program, DC Suite version 3.0. The results are as a follows: The results of comparison about total pants pattern shape, the ESMOD have two tucks of front and one dart of back and the Secoli and On&on have each dart of front and back. The results of estimation about total appearance, the On&on is the best of all pattern about total silhouette of front and back side and the ESMOD is the worst of all. In a case of the ESMOD, the thigh part has so many spaces between body and pants so it is rated low. When we examine about space between body and pants, amount of air gap of ESMOD is 0.6 at waist circumference and next is On&on(0.07). In case of hip circumference, the Secoli is 0.08 and the ESMOD is 0.14. The ESMOD's amount of air gap is 0.32 at thigh circumference and 0.62 at knee circumference. The Secoli's amount air gap is 0.26 at thigh circumference and 0.59 at knee circumference.

The purpose of this study is a men's dress shirt pattern by somatotype for mass customization system that is rising to the surface as a new production system. Subjects were 65 men aged from 25 to 44 for making research pattern and 9 men for wearing test. The dress shirt went through the secondary wearing test and sensory evaluation to verify the propriety of the research pattern. The results were as follows: For making research dress shirts pattern used the body parts size that were height, the circumference of the neck, the chest circumference, the length between biacromion, the arms length, and the waist circumference. The waist back length, the waist to hip length and the pattern length of were set by the calculation formula based on the height. The ease of 16cm for the chest circumference and A type had the ease of 10cm for the waist circumference, Y type had the ease of 8cm and B type had 12cm. Through the wearing test, the research pattern showed significant difference from the comparative patterns so additional two items of the length between biacromion and waist circumference were added to the items used in the comparative patterns through which satisfactory results were obtained. In the secondary wearing test for the dress shirt, all the items, except for the front centerline, were evaluated excellent. As a result of evaluating by the figure type, the normal type was evaluated best in all the items.

The purpose of this study was to develop an appropriate jacket pattern for elderly women over sixty years old, providing a good fit and appearance. Results were as follows: The length of the jacket was made long enough to cover the area 22.0cm below the waistline. The waist back length was made 1.7cm longer than the actual size of the waist back length. The armhole length was made 0.5cm longer than B/4, enhacing the appearance and functionality while allowing freer movement of the arms. As for the front and back interscye breadths, the front interscye breadth was made 1.7cm larger than the actual size while the back interscye breadth was only 1.0cm larger, providing the front interscye breadth more space. The bust breadth was made 10.0cm larger than the bust circumference measure(B/4+2.5cm), the waist breadth was made 6.0cm larger than the waist circumference measure(W/4+1.5cm), The hip breadth was made 12.0cm larger than the him circumference measure(H/4+3.0cm). The sleeve length was made 3.0cm larger than the arm length measure, as the sleeve length of a jacket is usually long enough to cover the ulnar styloid. The sleeve width was made 5.0cm larger than the upper arm circumference measure, as the upper arm circumference measure of the model pattern was too large than necessary, worsening the overall appearance. The sleeve cap height was set at AH/4+4.7cm. The wrist circumference of 27.0cm was set, allowing 2/3 and 1/3 for the large sleeve and small sleeve respectively.

This study held physical measurement for male subjects in their 20s living in Ningbo City, Zhejiang Province in China, showing the biggest market in men's clothes. Their representative lower body types with average shapes and sizes were chosen so as to develop men's slacks patterns with better dimension fitness. The following are the results of the analysis: 1. Slacks patterns were made based on the mean measurement values of 5 people, who were closest to the representative body types, from the index*absolute group of 47 people. The dimensions of application for slacks pattern-making were 77cm(omphalion waist circumference), 91cm(hip circumference), and 103cm(slacks length). 2. For the comparison of high-fitness and more-room pattern dimensions, 5 styles of slacks were made: Korean, Chinese, British, Japanese, and industrial. In the dressing fitness tests, industrial patterns had excellent appearance and Japanese ones had the best function. 3. Based on the analysis results of slacks pattern comparison, the target slacks were experimentally made and received superior evaluation points to the compared slacks patterns in two times of evaluation for appearance and function. 4. The final slacks pattern in this research had the following dimensions: front waist circumference: W(1-2cm with room included)/4-1cm, back waist circumference: W/4+1cm, front hip circumference: H(9$\sim$10cm with room included)/4-1cm, back hip circumference: H/4+1cm, crotch length: H/4-1.5cm, hip length: crotch length-H/12, front crotch extension: H/16-1.5cm, back crotch extension: H/8+3cm, knee line: 33cm below crotch line, front tuck amount: 4cm, back dart amount: 2.5cm(center) and 1.5cm(side), and back dart length: 10cm (center) and 6cm(side).

A Study using compare and analyze about differences among three patterns(shape and size of pattern, fitting and amount of air gap and so on) through 3D simulation. This study use 3D simulation program, DC Suite version 3.0. The results are as a follows: The results of estimation about total appearance, the pattern of Bunka is best of all pattern about total fitting and silhouette of front and back side. The pattern of armstrong and on&on stand low in estimation. As the total fitting, the pattern of Bunka is 4.40, the pattern of Armstrong is 2.60 and the pattern of On&on is 1.60. The result show better pattern of Bunka than pattern of Armstrong and On&on. When we examine about space between body and cloth, the pattern of Bunka is best. The pattern of Armstrong don't have problems about back side but front side have some problem of getting loose. Because it only have a waist dart so dart size is too big. The pattern of On&on have so much space because it don't have a waist dart. On the amount of air gap, the pattern of Bunka squash up body so it have the amount of air gap 0.08 at bust circumference and underbust circumference. Next is the pattern of Armstrong, amount of air gap is 0.14 at bust circumference and 0.23 at underbust circumference. The pattern of On&on's amount of air gap is 0.30 at bust circumference and 0.37 at underbust circumference. So the pattern of Bunka is bodice block of the best closing adhesion and the On&on is a loose-fitting pattern.

Background & Methods: In order to study the effect of electro-lipolysis-acupuncture, 57 outpatients who have had herbal medication in Kirin Oriental Hospital were devided to two groups; acupuncture-treated group(46) vs non-acupuncture-treated group(11) Acupuncture-treated group was given electro-lipolysis-acupuncture at least two times a week and administered with herbal diet medication, whereas non-acupuncture-treated group was administered only with herbal diet medication. Results: Mean age, body weight and BMI of these two group at the start point of the treatment were $27.22({\pm}7.64)\;vs \;29.09({\pm}8.73),\;67.76({\pm}9.34)\;vs\;67.00({\pm}10.69),\;and\;26.20({\pm}3.02)\;vs\;26.14({\pm}4.10)$ in the order of acupuncture-treated and non-acupuncture groups. After one month of treatment, change rate of body weight, BMI, total fat, percentage of fat was significantly higher in acupuncture-treated group. Also the change rate of arm circumference, hip circumference and thigh circumference was significantly higher in acupuncture-treated group. The change rate of abdominal circumference and WHR of acupuncture-treated group was higher than that of non-acupuncture-treated group with no statistical significance. The circumference reduction rate according to herbal dieting program was higher in this order, abdomen, arms, chest, thighs and hips. On the other hand, chest circumference change rate over weight loss rate, which is the portion no acupuncture treatment was given to, and AMC change rate was higher in non-acupuncture-treated group. Conclusion: These results imply that herbal dieting program combined with electro-lipolysis-acupuncture is more effective on reducing body fat, size reduction of localized obesity and preservation of muscle than herbal prescription only dieting program.
