Al 6061-T6를 사용하여 마찰교반 용접 시 회전 툴 숄더의 너비부의 넓이와 회전 속도, 이동속도의 변화에 따른 물성의 변화에 대하여 평가되었다. FSW 공정의 접합 변수에 따라 인장시험을 수행하기 위하여 KS B 0801 5호에 따라 시험편을 제작하여 마찰교반 용접을 시행하였다. 마찰교반 용접이 된 시험편의 기계적 특성을 평가하기 위해 Instron 인장시험기를 사용하여 1mm/min의 시험 속도로 인장시험을 시행했다. 평가결과, 인장강도는 회전 속도가 증가함에 증가 하였다. 툴 숄더의 이동 속도가 빠를수록 툴 유형에 관계없이 인장강도는 감소하였다. 툴 숄더 직경 12 mm (TSD12) 의 인장 강도 값은 일반적으로 8mm 보다 높게 나타났다. 이동 속도와 회전하는 속도가 한계 값을 초과하면 재료의 특성에 영향을 주지 않고 안정화 단계에 도달한다. 툴 숄더 직경 8mm (TSD8) 는 TSD12 유형의 공구와 비교하여 재료 특성이 감소하고 용접 영역에서 재료가 완전히 혼합되지 않는다. 인장 강도 값은 모든 회전 속도 1500 rpm에서 상대적으로 감소한다. 이동 속도가 낮을수록 같은 회전수에서 재료의 혼합될 수 있는 양이 많으므로 인장강도값이 높게 나타난다. 결과적으로 용접 영역에서 재료를 완전히 혼합하고 전이 온도에 도달하기 위해서는 임계값을 초과하는 회전 속도가 필요하다.

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.

The purpose of this study was to examine the changes brought by the upper body form using a three-dimensional human body measurement the gypsum method. The developed plane figure was constructed using paper replica to analyze the dimensional shape of the upper torso and to be able to design clothes suitable for elderly women's physical characteristics. The characteristics are analyzed and compared with existing patterns in order to extract the components for the pattern design. The examination was carried out based on the developed plane figures of upper body surface replicas. Type 1, the bent-forward body form, has a wide gap on the shoulder. In Type 2, the gap of waist line was wide at angulus scapulae point. Type 3 was the thin body form, and the girth of the chest, front interscye breadth and back interscye breadth were more level with one another, compared to the other types. In Type 4, the bent-backward body form, there was a wide gap on front shoulder. Comparison with the developed plane figure and existed pattern, items revealed differences in significance included the front and back interscye width between the measured values of the existed patterns and the developed plane figure. Therefore, the basic components of basic bodice pattern for old women were determined in the up-bust circumference and length of the back.

This study analyzed wearing conditions to develop an optimum sports brassiere for women in their 50s. A total of 35.9% of the women exercised three times a week and 51.1% had been exercising for more than 2 years, and 58.5% exercised for 30 minutes to 1 hour each day. Regarding the question of whether women wore a sports brassiere when exercising, 54.8% of the respondents answered 'No'. 73.9% of the respondents found a sports brassiere stuffy. The most important factors in purchasing a sports brassiere were wear comfort and functionality. In particular, more exercise demanded greater functionality. When purchasing a sports brassiere, the price range was the highest for 84.3% of the respondents at less than 50,000 won, and 45.2% preferred achromatic colors. A total of 47.9% preferred the length of the sports brassiere to be about 5 cm from the bust; however, the respondents who exercised more preferred shorter length sports brassiere. A total of 57.6% of the respondents preferred the width of the shoulder strap to be 1-3 cm; however, respondents who exercised more preferred the shoulder strap to be more than 3 cm wide. Most respondents preferred the sports brassiere to have a moderate degree of compression at the front breast area.

The purpose of this study is to improve clothing construction by analyzing form variation of upper trunk & upper arms with the use of plaster cast. Experimental research was performed by plaster gypsum method. The subjects were males between age 21 and 25, classified Standard somatotype by their bust size and Rorher Index. Arm movements were consisted of 5 types(0$^{\circ}$, 45$^{\circ}$, 90$^{\circ}$, 135$^{\circ}$, 180$^{\circ}$) to each vertical motion in front. The statistical analyses used in this study were mean, standard deviation, repeated mesure design. The result obtained from this study were as follows; 1. As a result of investigating into the rate of the expantion and contraction of basic body-surfact-lines, the side seam length showed the maxium rate of expantion in 180$^{\circ}$ degrees, the shoulder length showed the maxium contraction in the same degrees. 2. The variation of the upper part of the body form by increasing the upper limb motions, shoulder point was moved to be the inside or upside. And the anterior armfit point, posterior armfit point and armfit point were moved to upside. The form of the armhole-line in Drafts of a body surface was differently changed by increasing the movements. 3. Increasing the upper limb motions, the height of sleeve cap decresed and width of the sleeve decreased but girths of the sleeve cap was not show consistant change.

We have conducted surface photometry of a spiral galaxy NGC4419, by making use of photographic plates in U, B, V and R-bands taken by 105cm Schmidt Camera at Kiso Observatory. Two dimensional surface brightness distributions as well as luminosity profiles along the major axis are examined in detail to decipher the morphological properties of the galaxy. Analysis of the color distributions of NGC4419 shows that B-V and U-B colors remain constant throughout the galaxy with a weak trend of blue bulge in B-V color. The blue bulge might indicate an active star formation in the nucleus of NGC4419. For a quantitative analysis of the luminosity distribution of NGC4419, the observed luminosity profiles are decomposed into bulge and disk components, assuming the bulge component to follow de Vaucouleurs $\gamma^{1/4}-law$ while the disk component is assumed to be exponential. The fitting generally fails at the central part and at the shoulder near r = 15' where bulge and disk components overlap. The failure at the central part cannot be attributed wholly by the seeing disk since the core-radius of the central plateau is much larger than the width of point spread function. The failure at shoulder could be due to the luminosities from the spiral arms.
