  • Kushan dynasty was located in the middle of Silkroad, from the 1st century BC to the second century AD, where it negotiated with various races. Therefore, the culture of the Kushan has multi cultural elements. The purpose of this study is to understand the life of the ancient Silkroad by accessing this characteristic culture of the Kushan through costume analysis. And the results of this study will be used as a basic data for studying the relationship between Korean ancient costumes and Silkroad costume type. As a research method, literature survey and artifacts analysis were performed in parallel. The results of this study are as follows: The basic type of the Kushan costume was a typical nomadic ethnic type with a long tunic and trousers. Tunic was fastened with a belt and straps at the waist, and the lower part of the belt was wider like a skirt. The tunic was divided into two types: open front and closed front. Because Kushan was originally a nomadic people who lived in Central Asia, the nomadic elements of Central Asia remained unchanged in the early costumes of the Kushan, but over time the details of the costumes changed according to the surrounding political situation. When Kushan negotiated with Parthia, the parthian coat was worn by the influence of them. After occupying Greco Bactria, accepting the Greek culture of Bactria, Kushan's costume was supplemented by the external costume element of drapery, which changed the style of the nomadic costume into a elegant style.

  • The main purpose of this study is to derive a regression equation that predicts the individual differences in activity energy expenditure (AEE) using accelerometer during different types of activity. Two subject groups were recruited separately in time: One is a homogeneous group of 94 healthy young adults with age ranged from $20\sim35$ yrs. The other subject group has a broad spectrum of physical characteristics in terms of age and fat ratio. 226 adolescents and adults of age ranged from $12\sim57$ yrs and fat ratio from $4.1\sim39.7%$ were in the second group. The wireless 3-axis accelerometers were developed and carefully fixed at the waist belt level. Simultaneously the total calorie expenditure was measured by gas analyzer. Each subject performed walking and running at speeds of 1.5, 3.0, 4.5, 6.0, 6.5, 7.5, and 8.5 km/hr. A generalized sensor-independent regression equation for AEE was derived. The regression equation was developed fur walking and running. The regression coefficients were predicted as functions of physical factors-age, gender, height, and weight with multivariable regression analysis. The generalized calorie estimation equation predicts AEE with correlation coefficient of 0.96 and the average accuracy of the accumulated calorie was $89.6{\pm}7.9%$.

  • This study is historical research on the relationship between the Changes of the Form of costume and the recognition of the beauty of the body from prehistorical period to Ch'ing Dynasty in Chinese female costume. In figure painting a significant point was to describe the spirit of the figure so Chinese painters were less interested in ideal body pro-portion or body shape than Westerns. But idealized beauty of the female body existed and changed keeping abreast with the form of costume in each period. In the prehistorical period Wemen fasten waist belt so enabled to distinguish upper part of the body from lower one. "Locust-forehead moth-eyebrows(蝗首蛾毛)" recorded in "the Book of odes(詩經)" was the canon of beaty and Wemen tried to make their forehead broad and square from Zhou Dynasty to the Wei Jin periods. From the age of Civil War to han Dynasty Slender waist was loved so waist was tightly fastened and hemline became broader. in the course of that time Plump body in big cloth with broad sleeve emerged but that was less significant than Tang Dynasty. During Wei Jin and the Southern/Northern Dynasty undergo disruption and division they admired Taoist images. Loose fitting style with handkerchief hemline and broad sash belt was prevailed while miserable life was reflected gaunt face and lean body. Suk Dynasty also preferred a slim and long body silhouette. The style was presented extremely high waist line long and narrow sleeve slim and long skirt which expressed dynamic and straight image. The culture of Tang Dynasty was open and diverse and that character enabled blod decolletate revealing body line by tight fitting and special make-up-Social background of uion and stabilization made female body extremely plump full face. full breast and hips with most erotic image. The period of Kaiyuan Tianbao fashioned mannish disguise presented androgynous image. Five Dynasty and Song Dynasty restored standard body type so upper garments concealed neck and bust high waist line lowered which represented refined and simple outfit. But another eroticism emerged as foot-binding in Song Dynasty. For the sake of covering up deformed top of the feet and ankle gaiters and arrow shaped shoes were devised. During Ming Ch'ing Dynasties body shape became more slim weak and young causing to escort instinct that reflects 'Lust' or 'Mundanity'.

  • 인류 생활에 큰 위험과 많은 피해를 가져오는 화산활동은 오랫동안 지구의 역사와 함께 지속되어 왔다. 홀로세에 해당하는 약 1만 년 전부터 현재까지의 시기 동안 분화 이력이 있는 활화산들은 대략 1,520개로 알려져 있다. 이들 중 2010년 이후에 활동하고 있는 화산체들은 약 210여 개에 달한다. 2018년(2018년 1월 3일~12월 18일; USGS 자료)에 활동한 화산은 83개이다. 대략 지구상에서 1년간 평균 80~90여 개의 화산이 활동 중이며, 이 중에 90% 이상이 환태평양 화산대인 "불의 고리"(Ring of Fire)에 분포한다. 이는 지구상에 분포하는 활화산들의 80% 가량이 판의 수렴경계부에, 그리고 15% 가량이 발산경계부에, 나머지 5%가 판 내부에 위치하는 것과 잘 일치한다. 조사기간인 51주 중 특히 Aira(일본, 50회), Sabankaya(페루, 49회), Sheveluch(러시아, 49회), Ebeko(러시아, 49회), 그리고 Kirishimayama(일본, 40회)등 5개 화산에서 빈번한 화산 활동이 발생하였다. 화산활동의 뚜렷한 증감은 발생하지 않았으며 매년 비슷한 수준의 활동이 발생하고 있다.

  • Since Chinese cabbages weigh 3 to 5kgf and are big in size at the time of harvest, handling operations such as harvesting, loading and unloading including transportation require the highest labor demand among all other cultivation processes. Recently, though several cabbage harvesters were developed in Japan and Europe, those harvesters were not suitable for Chinese cabbages cultivated in Korea because of the size and shape. The cabbage harvester is almost meaningless without any proper cabbage piling and pallet unloading mechanism. Most harvesters developed so far adopted a sort of slide and free falling way in collecting cabbages into the pallet. Three or four labors are usually required for cleaning incoming cabbages and loading those in the pallet. Because of the required time for piling cabbages without severe damage and the required space capacity to carry empty and loaded pallets, harvesting speed should be adjusted in accordance with time required for consecutive operations. Up to now, any automatic or semi-automatic collecting device has not been developed in the world to pile cabbages on the layer one by one into the pallet in the ordered way with little damage and to unload pallet from the harvester continuously during the harvest process. To compromise system expenses and function, Semi-automatic cabbage piling and pallet unloading mechanism was devised and it required one labor. The foldable mesh pallet with a size of 1050mm x 1050mm x 1000mm and holding capacity of around 70 cabbages was utilized. The prototype for piling and unloading mechanism was composed of three parts such as feeding device, automatic piling device with retractable bellows, and pallet unloading device. Prior to developing the prototype, the geometric properties and the amount of the damage of the cabbage caused during the piling operation were investigated. Considering the height of the pallet, a series of cabbage carrying plates were mounted to the bracket chain to lift and to carry cabbages to the loading device. Indoor laboratory experiments showed that the cabbage carrying chain conveyor worked successfully. Considering the conveying speed 0.46m/sec of the pull up belt from the cabbages on the ground, the speed of cabbage carrying chain conveyor worked property in the range of 0.26m/sec to 0.36m/sec. The system allowed the operator to modify the position of cabbage slightly. Overall system worked successfully resulting into almost same capacity without severe damage to the cabbage as human did.

We can find the a corpus of song's words about cosmetic custom in Kor-ea. Which is 'Haecho' folk song in the souther-en costal regions 'Jinggum' folk song in Kim-hae regions and so on.... It's words is similar to Dunhuangsa in China. 3. Bichun inherited to China with India Bud-dism art in the middle of Dunhuang wall-pain-tings is one of the important Buddist saint. Sometimes it is painted with Giakchun Its arms of fly-dnacing in heaven with colored belt on body has almost the form of play on the musical instrument, We can see seasily the form in the painting of Buddist ser-mon. It was progressed and changed with the background of chinese traditional culture. When Dang's period came the color was chan-ged lighting dark blue has rhythmical and viv-id power of life. 4. Among the corpus of song's words which express the singers' system and rites of their tradition or habits. Dunhuang manuscripts des-cribes on behalf of the folk song's words in tra-ditional costume. This is following: (1) Naegagyo o sabyokwanja o Chyrasam o Rashang (2) Wangyesa o Sokryugun o Costume for fisher man (3) Bungajang of the chanboja o Ajang (4) Pongkwyun o Chongui (5) Tongsongs o Junofore (6) Namgaja o thin-Rasam (7) Yuchungnang o Hongsam o Sokryugun : The color of red costume (8) Kyongburak o Hongrasam o Sokryugun : Costume for charming woman Therefore traditional costume could be extracted according to the Dunhuang folk song's words out of culture such as learning rit-es three-obedience four-virtues and in-struction. As the same time it reflects ancient China's characteristics directly. I would endeavor to development for the history of the costume furher creative design and participat-ed in research activity with concerns forward continuously.

  • The Old Testament cotains mention of the history of creation and clothing in ancient Hebrew. This study dealt with Hebrew dress customs especially aimed at the manners of their hair styles, headgears, footwear and personal ornaments. References are Korean Revised Version, English King James Version and Revised Standard Version. There is little mention of hair styles and headgears in the Old Testament. Some sort of turban was worn by priests, and soldiers protected themselves with helmets, but most Israelitish men went bareheaded except on special occasions and often wear simple headbands. It was more common for women to use headwear of some type-turbans, scarves, and veils concealing the face. The veil was the distinctive female wearing apparel. All females, with the exception of maidservants and women in a low condition of life, wore a veil. It was the custom for women to wear a veil entirely covering their head in the public. Through most of the Old Testament periods long and thick hair was admired on men and women alike. The Hebrews were proud to have thick and abundant long hair, and they gave much attention to the care of their hair. The caring of hair was deeply related to their rituals. Nazirites never took a razor to their hair during his vow-days, but instead let it grow long, as an offering to God. Men would not cut their beards, but allow them to grow long. The Israelites' standard footwear was a pair of simple leather sandals. This was one of the items of clothing not highly prized. In a colloquial saying of the time, a pair of shoes signified something of small value, and to be barefoot except in times of mourning or on holy place, was a sign either of extreme poverty or humiliation, as in the case of war prisoners. Because precious stones were not mined in the Palestine-Syria region, Hebrews imported them from foreign country. They were consumer-to a large degree limited by their very modest standard of living-but not producers. Hebrews liked the precious stones and were motivated to acquire and wear jewels. Besides their use for adornment and as gifts, the precious or semiprecious stones were regarded by Jews of property. The Hebrews were not innovators in the field of decorative arts. The prohibition of the Law against making any "graven image" precluded the development of painting, sculpture, and other forms of representational art. Jewish men did not indulge in extravagances of dress, and there was little ornamentation among them. Men wore a signet ring on their right hand or sometimes suspended by a cord or chain around the neck. The necklaces, when worn by a male, also bore any symbol of his authority. Bracelets were extremely popular with both men and women, men usually preferring to wear them on their upper arms. The girdle was a very useful part of a man's clothing. It was used as a waist belt, or used to fasten a man's sword to his body, or served as a pouch in which to keep money and other things. Men often carried a cane or staff, which would be ornamented at the top. Among the women there was more apt to be ornamentation than among the men. Hebrew women liked to deck themselves with jewels, and ornamentation of the bride were specially luxurious and numerous. They wore rings on their fingers or On toes, ankle rings, earrings, nosering, necklace, bracelets. Their shapes were of cresent, waterdrops, scarab, insect, animal or plant. Sometimes those were used as amulets. They were made of ceramics, gold, silver, bronze, iron, and various precious stones which were mostly imported from Egypt and Sinai peninsular. Hebrews were given many religious regulations by Moses Law on their hair, headgears, sandals and ornamentation. Their clothing were deeply related with their customs especially with their religions and rituals. Hebrew religion was of monotheism and of revealed religion. Their religious leaders, the prophets who was inspired by God might need such many religious regulations to lead the idol oriented people to God through them.
