Background: Human body is formed of symmetric bilateral structures that are comprised of eye, upper arm, lower arm and etc. but, we are used only dominant components. The purpose of this study was to analysis length cognition ability in dominant eye & hand. Method: Total 180 persons (male 32, female 138) were participated in this study. They were tested with 'hole in the card' test for identification of dominant eye's side and the question for identification of dominant hand's side, then the length cognition ability was measured in right & left axillary level by describing 10cm line. Results: The results by independent t-test were as follows. In difference of length cognition ability in right axillary level between right dominant eyed group & left dominant eyed group, right dominant eyed group was superior to left dominant eyed group, but significant difference was not existed statistically(p>.05). In left axillary level, right dominant eyed group was superior to left dominant eyed group, but significant difference was not existed statistically(p>.05). In axillary level of dominant eye's side, non-crossed group was superior to crossed group, but significant difference was not existed statistically(p>.05). In axillary level of non-dominant eye's side, non-crossed group was superior to crossed group, but significant difference was not existed statistically(p>.05). Conclusion: These result can be applied to the learning of palpation & observation skill in physical therapy.

여성복에 있어서 09/10년 시즌에 가장 주목할 만한 특징은 파워 숄더 룩이다. 파워 숄더 룩은 단순히 패션니스타들에서만이 아니라 당당히 스트리트 패션의 하나로 자리 잡았으며 파워 숄더 룩의 50%이상을 차지하는 재킷이 여성복의 핵심 아이템의 하나로 부활하면서 재킷의 어깨 각도는 0도에서 30도 이상까지 다양하게 나타난다. 다양한 어깨 각도 중 10도, 15도, 20도의 형태가 70%이상을 차지하고 있으며 패턴의 형태는 몸판의 어깨선을 자연스럽게 올리고 확장한 어깨변형 패턴, 어깨선과 함께 소매산 부분을 절개한 소매산 변형 패턴, 몸판과 소매가 연결된 패턴이 주를 이루고 있다. 파워 숄더 패턴 전개는 어깨 각도가 높아질수록 각이 시작되는 점이 목옆점에 가깝게 하고 어깨끝점이 확장되어야 소매의 외관형태가 편안하고 피트성이 좋아진다. 어깨 변형의 경우 앞뒤 진동선의 시작점인 어깨점과 소매산의 정점 부분의 선이 완만하게 이어지도록 S라인형태를 유지하는 것이 가장 중요하며 소매산의 ease분량이 일반 재킷 소매보다 많아야 파워 숄더 실루엣이 자연스럽게 연출된다. 소매변형 패턴은 중심쪽 소매의 소매산 높이는 기본소매 소매산높이의 1.5cm를 외곽 소매분량으로 처리한 것을 고려하여 소매산 높이를 설정하고 어깨 각이 커질수록 외곽소매의 소매산 폭을 크게 함으로서 소매의 어깨점이 목옆점 방향으로 휘지 않고 각이 선 파워 숄더가 완성된다. 소매변형과 소매와 몸판연결 패턴의 경우 어깨점과 상완이 연결되는 부분에 충분한 여유가 필요하며 어깨각도도 다른 형태에 비해 상대적으로 낮아 보인다. 이와 같이 파워 숄더 재킷 패턴은 패턴 제작시 디자인적인 요소를 충분히 감안한 패턴 설계와 함께 소매의 달림선 위치, 어깨너비, 어개 높이 확장량, 소매통의 여유량 등을 고려하여 제작하는 것이 바람직하다.

Hot-Press-Forming (HPF), an advanced sheet metal forming method using stamping at a high temperature of about $900^{\circ}C$ and quenching in an internally cooled die set, is one of the most successful forming process in producing crash-resistant parts such as pillars and bumpers with complex shape, ultrahigh strength, and minimum springback. To optimize conditions of a forming quality in HPF process and secure a safe product without any failures, such as fractures and wrinkling, the simulations based on the coupled thermo-mechanical analysis for a hot-press-formed lower control arm are applied with Taguchi's orthogonal array experiment. Three factor variables - the friction coefficient, blank shape, and hole location for burring - are selected to be optimized. The most effective condition of a forming quality for a hot-press-formed lower control arm is suggested. The simulation results are confirmed with experimental ones.

The acromioclavicular-hook-plate is one of the surgical treatments for distal clavicle fracture and traumatic acromioclavicular (AC) joint dislocation. Although this procedure can obtain rigid and accurate anatomical reduction of the AC joint, secondary widening of the hook-hole in the acromion is often seen during postoperative follow-up. This complication is owing to the high-degree of mobility of the AC joint. Therefore, it is important to evaluate the effect on these complications due to the position of the hook-hole. The purpose of the present study is to investigate three-dimensionally the effect due to the position of the hook-hole during arm abduction motion. We studied in vivo and three-dimensional kinematics of the normal shoulder joint with use of a markerless bone-registration technique. Magnetic resonance images of 14 shoulders of 7 healthy volunteers were acquired in 7 positions between $0^{\circ}$ and $180^{\circ}$ of abduction. We created three-dimensional computer models of the bones and the acromioclavicular-hook-plate. Based on the three-dimensional kinematics data, we simulated the widening of the hook-hole each different positioning of the hook-hole. The widths of the hook-holes almost linearly increased. And these widths significantly increased, when we put the hook-hole on the acromion from AC joint to 20 mm and 25 mm posterior position.

Assembly tasks are often performed by one robot with fixtures. This type of assembly system has low flexibility in terms of the variety of parts and the part-presentation the system can handle. This paper addresses assembly without fixtures using two-manipulator robot. An active method using force feedback is proposed for the peg-in-hole assembly in highly uncertain environment. Assembly states are defined as status having unique motion constraints and events are modeled as variation of the environmental force. The states are recognized through identification of the events using two 6-d. o. f. force/moment sensors. The proposed method is verified and evaluated by experiments with round peg-in-hole assembly.

In this paper we present a new visual approach for the robust bin-picking in a two-step concept for a vision driven automatic handling robot. The technology described here is based on two types of sensors: 3D laser scanner and CCD video camera. The geometry and pose(position and orientation) information of bin contents was reconstructed from the camera and laser sensor. these information can be employed to guide the robotic arm. A new thinning algorithm and constrained hough transform method is also explained in this paper. Consequently, the developed bin-picking demonstrate the successful operation with 3D hole object.

Assembly is usually performed by one robot and fixtures. This type of assembly system has Low flexibility in terms of variety of parts and part-presentation that the system can handle. This paper addresses assembly without fixtures using two-manipulator robot. An active method using force feedback is proposed for the peg-in-hole assembly in highly uncertain environment. Assembly states are described by extended contact relations. Qualitative templates for events are easily derived from the token vector of the Petrinet model. The states are recognized through identification of the events using two 6-d.o.f force/moment sensors. The proposed method is verified and evaluated through experiments with round peg- in-hole assembly.

This study mainly analyzes that designing patterns of an adult women Jeogori that takes advantage of patterns from each textbooks and complements the disadvantages based on the analysis of data from the dress evaluation and comparison of materials. The modification of a size specification is needed for the standard body as an adjust of the length of Jogori between front and back, mediation for bust width between front and back, a movement for the based line of Sup and Godae. As a result, the suitable pattern according to the standard somatotype is as below. Jeogori Length of front is determined by the length of back which was measured from side neck point to bust point plus three centimeters, and give three and half centimeters more in front. This three and half centimeters is for the curved in front of your body due to the chest. Bust width of front and back have to show the differences of human body. Bust width of front is calculated as bust girth into quarters and add two centimeters. Bust width of back gives one centimeter behind the curve from the center line in order to reduce the floating phenomenon. So, the amount of center back line dart is one centimeter. Arm hole girth measures as dividing bust girth into four. Also, Goedae width has two methods to measure. First, divide bust girth into ten equal parts and subtract 0.5 centimeters from it. Second, measure neck girth and divide it by four. Sleeve length is equal to Hwajang minus bust width of front. Hand wrist calculates in using bust girth. Make bust girth into quarters and multiply three fifths. Side line measures as deducting from Jeogori length of back to Arm hole girth and multiply two thirds.

Objectives The aim of this study was to investigate the effects of Cannabis Fructus on exercise capacity and cognitive function in chronic hypoperfusion induced vascular dementia rat model. Methods Vascular dementia rat models were induced by chronic cerebral hypoperfusion through bilateral common carotid arteries occlusion (BCCAO). All rats were randomly divided into 4 groups: normal group; control group; CF I group (feeding Cannabis Fructus 100 mg/kg); CF II group (feeding Cannabis Fructus 300 mg/kg). In order to study the effects of oral administration of Cannabis Fructus on vascular dementia rat models, corner turn test, hole board test, radial arm maze test, passive avoidance test were taken and Acetylcholine (ACh) activity, Acetylcholinesterase (AChE) activity, serum of Vascular endothelial growth factor (VEGF) protein level were measured. Also histological findings of the liver, kidney, brain and the change of Tau immunoreactive neurons in hippocampus were observed. Results CF I and CF II showed significant improvement in corner turn test, hole board test, radial arm maze test, passive avoidance test, Acetylcholine (ACh) activity, Acetylcholinesterase (AChE) activity, the serum of Vascular endothelial growth factor (VEGF) protein level and the change of Tau immunoreactive neurons in hippocampus. CF I showed more significant effect than CF II in these tests. However in histological observations of the liver and kidney both CF I and CF II showed glomerular injury and hepatotoxicity. Conclusions These results suggest that Cannabis Fructus was helpful in improving exercise capacity and cognitive function on Chronic hypoperfusion induced Vascular Dementia rats. However Cannabis Fructus affects the liver and kidney, therefore suggest that this is an area for further study.

False sleeves are 'the sleeves that are attached to clothes but exist just as a part without any function to put arms in them.' They are different from sleeves to put arms in them and are to follow the trend or a way of wearing clothes. They are mostly found in medieval Europe's decorative sleeves named 'Hanging sleeves', but they are also found in Eastern region, too. They are found in sleeves that attached women's headgear in East and Middle Asia, and also in high-class male caftan in Ottoman Turk in the 16th and 17th century. False sleeves can be divided into two kinds by shapes. The first ones are the decorative sleeves of which trunk-shaped sleeves hang around the whole or part of the arm hole but have no function to put arms in them; this is called as 'sleeve-shaped False sleeves'. These sleeves are found in women's headgear in medieval Europe, Ottoman Turk, and East and Middle Asia. False sleeves in Europe and Ottoman Turk played a role in showing wealth and power while those in East and Middle Asia had a great role in highlighting the costume's decorative effect. The second ones are the sleeves hanging down from the arms by attaching long cloth to the arm hole, in design; these are named as 'cape-shaped False sleeves.' This style is found only in medieval Europe, and presumably, these cape-shaped false sleeves may have played a role in boasting of one's wealth and power.
