Materials produced with the help of new technology are used in the design of materials used in all science and engineering departments today. A sports engineering and sports equipment department is one of these departments. The use of nanotechnology in sports equipment is one of the most popular uses of this technology today. Nanomaterials have been used in sports equipment for many years, and reputable companies have benefited. Athletes' equipment allows them to display their skills to the fullest extent. It has always been a dream of professional athletes and their coaches to have unique equipment. As a result, engineers have spent all their time and effort solving this problem. Science and engineering can do various things to meet the needs of all sports levels, including specific and detailed designs, the use of appropriate materials, and standardization tests on equipment. However, these aspects must remain aligned with the latest technologies as they develop, just as with other sciences. These technologies, especially nanotechnology, are essential to sports equipment and devices developed today by sports engineers. This article examines the balls that use nanotechnology and can also improve the athlete's performance by using this technology in a specific structure. Using nanotechnology to make nanocomposite poly-hope balls, which makes them lighter and more acceptable, reduces the impact on the ball and increases its movement speed.

The purpose of this study was to compare the appearance similarity between a 3D virtual wedding dress, and a model wearing real dress, and production efficiency, and the possibility of achieving similar results with 3D digital technology. Five wedding dresses for small weddings under the theme of 'Dream Series', were designed and produced in virtual and real dresses to quantitatively compare and analyze the appearance similarity and production efficiency. Experts compared the appearance similarity on the silhouettes, colors, materials, and details, and production efficiency was compared with time and cost. Based on our results, 3D virtual images of four out of the five dresses were similar to the real images. Our efficiency evaluation results showed that the manufacturing time was 45.4% shorter, and the manufacturing cost was 46.1% less than the existing method. This indicated that the wedding dress manufacturing process using 3D virtual software was time and cost saving competitive. Our results also confirmed that 3D virtual software technology has the potential to increase the efficiency of designing and production, and therefore an increase in competitiveness and sales of wedding dresses. Furthermore, 3D technology allows consumers to select and order wedding dresses online through 3D virtual software. This is a great advantage, and it highlights the significance of this research study.

Nepal's role in the expansion of Mahayana Buddhism beyond the Himalaya is very significant. Nepal became the center of Mahayana Buddhism after the Muslim invasion of Nalanda Mahavihara in the 1199 A.D., which she maintained almost for 300 years. During this period, Nepal had produced a large number of profound Buddhist scholars. Most of them were the teachers of eminent Tibetan Buddhists. Some of the Nepalese Gurus also has continued lineage in Tibet until now. During that time, every Tibetan had desire to go to Nepal for higher Buddhist learning. As a matter of fact, many Tibetans made arduous journey across the Himalaya to fulfill the dream. Tibetan studied various forms of tantra, precepts, logic, doctrine, Sutra, Sadhana, Doha, Charyagiti, meditation etc. under direct supervision of Nepalese teachers. Great Tibetan scholars such as Marpa, Rwa Lo, Chag Lo, Khon phu ba, Klog Lo, Gos Lo, and others were the product of Nepal's scholarly tradition. They have significant place in the history of Tibet. Nepalese scholars also frequently visited Tibet where they taught Buddhism in various monasteries. They also had major role in propagating tantra in Tibet. Tibetans firmly believe that it is not possible to attain enlightenment without practicing tantra. The contribution of Nepalese scholars was so profound that Tibet produced many eminent scholars who developed scholastic tradition in Tibet. But after 14th century, Nepal's scholarly tradition ceased to continue. Then after, Tibetans started to call them 'the dull'.

이 논문은 오스망에 의해 주도된 파리의 변화를 발작과 보들레르의 작품에 등장하는 배회자를 통해서 분석하려는 시도이다. 두 작가의 작품 모두 근대성을 표상하는 배회자가 파리의 시가지, 특히 건축물들을 관조한다. 근대성을 표상함에도 불구하고, 배회자들은 양가적으로 과거의 유산에 빠져있기도 하다. 발작의 『파리의 그릇된 면모』에서 남성 부르주아인 고드프와는 과거의 유산인 오래된 건축물들을 관조하는 배회자이다. 보들레르의 시 「빅토르 위고를 위한 백조」에서 근대의 카루셀을 지나는 배회자는 과거의 파리가 사라진 것을 느낀다. 「파리의 꿈」에서 환영화된 파리는 나폴레옹 3세가 장려한 자본주의적 활동에 의해 형성된 대도시의 이미지를 보여준다. 두 작가의 차이는 근대성이 파리를 어떻게 변모시켰는지를 예시해주고 있다.

This study aimed to find out the difference of ordinary symptom according to Sasang Constitution and Gender. We collected 1241 subjects who had been diagnosed by the Sasang Constitution specialist and confirmed with Sasang Constitution drug response in the thirteen oriental hospitals. We researched ordinary symptoms through a paper and used Chi-square test to know association between items and Sasang constitution. There are significantly different items according to Sasang Constitutions statistically, which are "amount", "speed", "indigestion" and "appetite" in meal, "amount", "feeling after sweat" in sweat, "thickness" in feces, "foam" and "frequency" in urine, "sensitivity and hand, feet of part" in heat and cold" and "amount and habit" in drinking water". In male, "indigestion", "frequency in urine", "a lots of dream" and "hard to sleep" in Soeumin, "sweat in head and face" "foam of urine" and "warm of abdomen" in Taeeumin were different among Sasang Constitutions. In female, "sweat in chest" in Soeumin, "short time of feces" in Soyangin were different among Sasang Constitutions. From the above results, ordinary symptoms were different according to Sasang Constitutions. and in some part, there are also gender differences of Sasang Constitution.

It is well known that the general metals have a lot of grain boundaries. The grain boundaries play a negative role to increase the resistivity and to decrease the conductivity. The small resistivity and the large conductivity have been a goal of the material scientists, and no signal noise, perfect signal transfer, and the realization of the real sound are the dream of electronic engineers and audio manias. Generally, oxygen free copper (OFC) and Ohno continuous casting (OCC) copper cables have been used for the purpose of the precise signal transfer and low noise. However they still include a lot of grain boundaries. In our study, we have grown the single crystal by the Czochralski method and succeeded to produce single crystal wires from the crystal in the dimension of $0.5{\times}0.5{\times}2500mm$. The produced wire still possesses very good single crystal properties. We observed the structure of the wire, and measured the resistance and impedance. Glow Discharge Spectrometer (GDS) was used for analyzing the compositions of copper single crystals and commercial copper. Current-Voltage curve, resistance, total harmonic distortion and speaker frequency response were measured for comparing electrical and acoustic properties of two samples.

In order to anticipate gradual increase of fault current in electric power systems, current limiting technology and current limiting device has been investigated for a long time. But the commercial use of current limiting device was delayed due to the lack of effective method to insert impedance to the elective power systems without loss and surplus defects. However, novel current limiting device, which use superconducting materials, was considered as a dream technology to be applied in a distribution and transmission lines. LG Industrial systems and KERPI started to investigate resistive type superconducting fault current limiters in order to develop 154kV fault current limiters and this year, we succeed to test 3 phase 6.6kV/200A fault current limiters. Based on these achievements, 24kV superconducting fault current limiters will be realized withing 3 years which could be tested in a real fields. In this paper, the developments of fault current limiting module which use YBCO thin films, cryogenic systems, the structure and construction of 3 phase fault current limiters and finally the test results of 6.6kV superconducting fault current limiters will be introduced.

The purpose of this research was to find out the differences in the moving motivation and life satisfaction of senior cohousing communities between male and female residents in Scandinavia, especially in Sweden and Denmark. Senior cohousing is an attractive housing alternative for the aged 55 and over who looks for sharing one's life with neighbors. The 655 survey questionnaires out of 960 had replied from 14 Seniorbofrellesskaber in Denmark and 11 seniorhus within SABO sector and 8 housing cooperatives initiated by the Seniorgarden Housing Company in Sweden during April to May, 2002. The data were analyzed by SPSS win program, using frequencies, percentiles, cross-tabulations, and Pearson's correlations. The results showed that the senior cohousing residents were generally healthy and age of 70's years old and nearly half lived with a spouse. The male residents lived with a spouse about 2 times more than did the female. The residents had very strong motivation to move into the community and very high life satisfaction. Most aspects of moving motivation were not differed by the sex of the residents. However, male residents were more likely than female to be motivated to move in by becoming a pensioner, while female residents were more likely than male to be motivated by being a widow, looking for safety, or avoiding loneliness. These different motivation to move in by sex become more clear when general characteristics such as age, health status, living with or without a spouse, or country were controlled. Female residents were more likely than male to live' dream life' in the senior cohousing community. The stronger the moving motivation, the higher the life satisfaction in the community.

1. Objectives : There are many studies on the ordinary symptoms based on Sasang constitution. But there are not quite satisfactory between the types of Sasang constitution. So This study is for learning the characteristics of ordinary symptoms depending on Taeyangin Soyangin(the rest Yangin) and Taeumin Soeumin(the rest Eumin) of the Sasang constitution. 2. Methods : We classified them into the each type of Sasang Constitutional Medicine(SCM) by the well-trained SCM specialist, and assessed their ordinary features by the questionnaire. Binary logistic regression analysis was applied to evaluate the influence of ordinary features to the diagnosis of SCM. 3. Results : There are a result of the binary logistic analysis on the observed questionnaire. 1) Regarding sleeping, Yangin do not dream much as Eumin do when they sleep. The time they are sleeping is not longer, and they usually do not sleep well. 2) Regarding stools, Yangin go to stool more than Eumin do. The constipation does not occur when they are not in a good condition, and they do not feel uncomfortable when they do not go to stool for a day. The length of time taken for emptying the bowels is much longer, and the hardness of their stools is much more, but the hardness does not mean that they have the constipation. 3) Regarding urine, Yangin have much more foam than Eumin. 4. Conclusions: We found that Yangin and Eumin have characteristics of ordinary symptoms, but partly there are not in accordance with ones what Lee Je-ma said in his book. So in future we hope clinical studies are required steadily.

스카이브릿지가 연결되는 건물에 강접합될 경우에는 비정형성이 크게 되어 지진하중에 매우 불리하게 거동할 수 있다. 따라서, 마찰진자베어링(FPS)이나 납고무베어링(LRB)와 같은 연결시스템을 사용하여 스카이브릿지와 구조물을 연결하게 된다. 이러한 연결시스템은 큰 지진하중이 발생하였을 때 스카이브릿지가 연결된 건물에서 분리되어 낙교하지 않도록 신중하게 설계되어야 한다. 본 논문에서는 수직방향 인장력에대해서 저항성이 없는 마찰진자감쇠기를 이용한 연결시스템을 설계하는 과정에서 반드시 검토해야할 사항을 분석하였다. 이를 위하여 실제 시공된 누리꿈 스퀘어를 예제구조물로 선택하였고 예상되는 지진하중이 가해졌을 때 스카이브릿지 연결시스템에서 발생하는 응답을 분석하여 낙교를 방지할 수 있는 설계 프로세스를 정립하였다.
