The process of weaving fabrics with high levels of tension and abrasion can cause damage to the yarn threads. To protect threadlines during the process, a protective polymer is coated on the surface of the yarns prior to weaving. This application process is known as slashing. The current slashing system is incompatible with today's demand activated manufacturing strategies. Methods of improving the uniformity of polymer coating application were studied, and several applicators were designed and evaluated. Prewetting of the threadlines before coating application was shown to greatly improve coating uniformity. The objective of the research is to design a single-end slashing process that is environmentally friendly and will improve productivity and flexibility.
Recently, a study on alternative and renewable energy is being conducted due to energy depletion and environmental problems. In particular, a hydrogen has the advantage of converting and storing the remaining energy into water-electrolyzed hydrogen through renewable energy generation. In general, due to reasons such as insulation problems, a study on high-pressure hydrogen storage tanks and related parts has recently been conducted. However, in the case of liquid hydrogen, the volume can be reduced by about 800 times or more compared to high-pressure hydrogen gas, so the study on this is needed as a technology that can increase energy density. In this study, the evaporation characteristics were analyzed under fixed heat flux conditions for liquid hydrogen storage tanks and the change in thermal stratification according to sloshing was analyzed. The heat flux condition was fixed at 250 W/m2 and the horizontal resonance frequency of the primary mode was applied to the storage tank. As a result, it was confirmed that the thermal stratification phenomenon decreased compared to the case where the slashing was not present due to forced convection when the slashing was present.
This study aims to suggest desirable directions through analyzing English test items of college entrance examinations(CEE) in Korea, China, and Japan. To achieve this, English test items of Scholastic Ability Test(SAT) in Korea were compared with those of CEE in China and Japan, and test items of TOEFL and IELTS. It was found that there were not many items for testing productive skills relatively to the tests of other countries including TOEFL and IELTS. Especially, there were integrated items for writing test in China. In case of speaking test, all the other country adopted direct ways like interview and oral test, not indirect test as in the SAT in Korea. It is suggested that there need to be included test items comprising long passages in order to measure extensive reading ability. It can be suggested that doze test be adopted for testing integrated proficiency of English.
Vest is a general term for a sleeveless upper garment and it derives from a kolobus of a sleeveless tunic style that was started to be worn as a substitution of a chiton by the peasantry in Greek period. The kolobus started to be called a colobium or a tunica from Roman period and the former was named for a vest style tunica which was worn by the people of the lower classes in early Roman period. Similarly, a German colobium of North Europe which was worn during the same period was the same kind of clothe as the Roman colobium. The colobium came to be worn over a dalmatica as an outer garment by early Christians when it was the Middle Ages, who succeeded the tradition of colobium as they went through ancient Rome, Creek and Byzantine days. North Germans also succeeded the colobium tradition of ancient Germans as it was and so continued to wear it in tight style. The simple vest style of colobium was getting vanished from the mid of the Middle Agnes and a new style of vest named jupon was started to be worn by soldiers. The jupon was to protect soldiers' bodies from either were cold weather or enemies wearing under armors as it was made with double cotton pad by quilt. From 14th century, the jupon began to be worn by not only soldiers but also the humble of lower classes. All the jupon which were made in quilting and padding of that time began to be named a pourpoint by the humble. When Renaissance in 16th century came, the pourpoint began to be developed to an exaggerating body-line style. The neckline of pourpoint was getting highly influenced by Spain and a peacecod-belly of it emphasized the exaggerated masculine beauty of Renaissance by padding in round. The sleeves were puffed out and the whole purpoint was made to expose an inner chemise by slashing vertically or obliquely. But in 17th century, the pourpoint has been changed into more simple style without padding, puffing out and slashing influenced by the citizens' clothes of Netherlands. The pourpoint came to be more comfortable bulky style with short sleeves or sleeveless and straight side lines. The pourpoint in mid 17th century turned to be a bolero jacket style by gradually being tightened. It had been then changed into a vest style with sleeves and worn under an overcoat with the name of vest in the end of 17th century. The early vest was 2∼3 inches les in length than the overcoat and had long sleeves and many ornamental buttons on front. It was also made as a home wear to be worn it alone at home. In 18th century, the length of the vest became shorter compared with that of 17th century and the most important decorative item in clothes. It again came to have complete sleeveless vest style and had very short length reaching waist in the end of 18th century. When it was in 19th century, the vest had developed into more various style and colors and style had been applied to be worn by individuals with their tastes. Around the end of 19th century, the increasing tendency to be casual by industrialization influenced on clothes in all aspects of life and so the male vest has been gradually changed into more casual style. Nowadays, it has been developing into various uses in modern male clothes to show their characters.
In the comprehension of English texts, Korean students generally try to translate English into Korean in accordance with the word order of Korean language. As a result, the comprehension of English texts is made in a regressive way, which results in slower reading. In order to enhance the reading speed, it is necessary for students to practice progressive reading. Also, while reading English texts, most readers' eyes tend to look at one word at a time, which actually cuts down on the reading speed. Reading by the sense group of as many words as possible at a glance, however, can help a reader more efficiently in less time. This research aims at developing the Powerpoint program for progressive reading by the sense group according to the student's level. In this program, as for methodology, the technique of rooking it fade-away is introduced to force a reader's eyes to move fast. Through this technique, it is possible to make a line of the texts disappear on the screen and make another line appear, which enables a reader to sweep the words across each and every line of the reading material smoothly without regression.
Mannerism style evolved from the Renaissance style adopting the concept of grace as the ideal beauty, Having its ground on Neoplatonism the main goal of mannerism art was the realization of the invisible beauty over reality. Mannerism style in dress flourished in the sixteenth century court society, when courtly manners and courtly grace became the most important qualities in social relationship. Courtiers thought that courtly grace the ideal of beauty could be realized in the cultured and studied elegance. Mannerism style in dress evolved from the process of transforming and manipulating the Renaissance look for the abstract of beauty. The clothes of Mannerism style were against the natural movement of the human body. There was a tendency of refining and polishing the whole clothing and various technical skills were experim-ented on the mannerism style. The outstanding elements of this tendency can be found in the details like ruffs fathingale padding slashing puffing and etc. Mannerism intended to reconstruct the human body artificially to express courtly grace and novelty. During that process the new pose 'figura serpentinata' which is bizarre convoluted pose with full of flexibility was created. The expression of human body became more slender with elongated legs a torso with a long neck and a tiny head. This tendency of distorting the natural body forms were reflected in the formal characteristics of Mannerism dress style which is geometrical abstr-action unnatural elongation complex disposition and control with perfect ease.
In fashion there was a move away from the ascetic of the Gothic according to the appear-ance of a new spirit at the beginning of the fourteenth centuries initially in Italy. The new spirit Humanism applied their interest not to the universal but to the individual and particular. The Renaissace costume style based on the Humanism was sharp angled and curvy and had a grotesque silhouette with the exaggerated and tense decorations. The purpose of this study is researching the background led to the balanced costume style characterized by unique details. out of the tastte for luxury and beauty grew a new style known as slashing in which seams were left open and colored linigs thrust through or cuts were made in an entire cos-tume and contrasting material puffed out of the cuts. With the slashes another element was characterized in the high Renaissance cos-tume style that was the use of points or lace to hold a costume together. For the masculint costumes pads became into a fashion and were used for forming the antinatural artificial and bulky silhouettes. The body was distorted and tensed by putting the pads into the sleeves and bodice. The jacket with a full rounded bodice like a bow known as peascod belly and haut de chausses a onion-shaped trunk hose with a codipiece ap-peared and grew one of the most characteristic of Renaissance style. According to these sociological changes the view of the beauty based on the human body and in both of men and women the costume style was changed very much to emphasixed their physical beauty and finally it grew a grotesque style and even more a exposed style that exposed a part of their body. Those backgrounds as were stated above can be said to lead to the appearance of the grotesque style in the Renaissance Age.
Purpose: Median nerve entrapment syndrome within carpal tunnel is usually called carpal tunnel syndrome and it is the most common form of peripheral nerve entrapment syndrome. Many factors such as diabetes mellitus, hypothyroidism, hormonal replacement theraphy, corticosteroid use, rhematoid arthritis and wrist fractures may cause carpal tunnel syndrome. To the best of our knowledge, this is the first case report of median nerve entrapment syndrome due to adhesion of laceration wound after suicidal attempt. Methods: A 28-year-old woman presented with a sensory change and thenar hypotrophy on her left hand. On her history, she attempted suicide by slashing her wrist. Initial electromyography (EMG) showed that the nerve conduction velocities of median nerve was delayed. Therefore, we performed surgical procedures. When exploration, Fibrous scar tissue observed around the median nerve but nerve had not been injured. Transcarpal ligament was completely released and adjacent fibrous tissue was removed to decompress the median nerve. Results: The postoperative course was uneventful until the first year. Opposition difficulty and thenar hypotrophy were improved progressively after the surgery. Sensory abnormality was slowly improved over one year. Conclusion: We report a case of median nerve entrapment syndrome that was caused by adhesion of laceration wound after suicidal attempt. This is an unusual cause of median nerve entrapment syndrome, the symptoms were relieved after transcarpal ligament release and fibrous scar tissue removal.
This study aims at considering and analyzing the stature of denim clothing as an ornament as well ai how aesthetic meaning and human being's mental side indwell in the development of denims. which will be proceeded in the future, from the view of contemporary culture of dressing. It is found that the stylishness expressed through denim clothing is formed on the basis of the cultures of party, drawing and disorganization, and the result of the study was as follows. Firstly, the culture of party became the source of for decoration of denim clothing, and denim clothing more glamorize women as a party-look which makes the most use of its advantage to be comfortable and able to display in various ways with splendid artificial jewelry, patchwork, dyed pattern which is elaborately embroidered. Secondly, Such culture of drawing is applied to denim clothing so that denims are expressed to make people feel more human being's warmth as being free from the existing stereotype and formality. Thirdly, the most outstanding feature of denim clothing showed in the culture of disorganization is to make the most use of vintage style as it is. This reflects an image of the culture of disorganization under postmodernism, which is free from the traditional conception of the existing dressing by destroying the original form, in the way of slashing, making a hole and tearing. That is, people can sufficiently express not only free sense of release based on postmodernism by wearing denim clothing, but also human being's intrinsic desire for restoration of humanism or human warmth with splendid decoration or various techniques such as handicraft. It can be recognized these features as the reasons, that make denim clothing place themselves as an original fashion item, by giving denim clothing technical decoration in recent years.
