A refined three-dimensional finite element interaction model between the high-speed train and railway bride deck has been developed in the present study. Analytical predictions of vertical deflections for a railway bridge are compared with in-situ test results and a good agreement is achieved. Then, input variables employed in the analytical comparisons are selected as random variables for the limit state functions. followed by risk assessment. For this purpose, a linear adaptive weighted response surface method has been developed and applied. A typical railway bridge has been selected and the limit state functions are employed from UIC and Korean specifications in the comparative studies. The results reveal that Korean specifications give significantly risky reliability indices in comparison with UIC specifications. It is thus encouraged from the above that the present linear adaptive weighted response surface method can be an alternative for the fast estimation of nonlinear structural systems.

Noeui was a garment used for women's outfits and robes. In the late Joseon Dynasty it was a special garment that could only be worn by the class belonging to the royal family. Noeui was especially prepared as a wedding dress, and was worn by the bride at the Chinyeong ceremony on the day of the wedding ceremony. Until now, Noeui did not have in depth research at the costume history despite its importance as a royal costume in the Joseon Dynasty. Thus, based on Uigwe for the Royal Wedding Ceremony of King Injo and Queen Jangryeol (which is the only material with a diagram of Noeui and its pattern) this study historically investigated and restored the Noeui set of Queen Jangryeol, which was arranged in 1638, when King Injo and Queen Jangryeol were married. This academic study is the first to historically confirm and restore Queen Noeui's set, and rigorously analyze the historical materials as well as provide new comments on the shapes of Noeui's Git and the front side.

Hallux valgus deformity has been slowly getting popular in Korea. Many surgical procedures are available for treating the hallux valgus, but it is still controversial for the best treatment. We operated 25 feet(15 patients) of hallux valgus between May. 88 and December. 94. The clinical results were as follow ; 1. Age distribution was 25 to 82, and all female. 10 patients have bilateral hallux valgus. 2. 19 feet were treated by soft tissue procedures only and 6 feet by combined soft tissue and bony procedures. 3. Bunion deformity was recurred in 2 feet (1 Patient) which were treated with modified McBride Method. 4. Lateral sesamoidectomies were performed in 7 feet without development of hallux varus. 5. The cosmetic and functional results were good in 6 cases treated by proximal metatarsal osteotomy. 6. 9 feet had other digits deformities, which need surgical correction. 7. Tightening repair of medial capsule seems to be important for prevention of recurrence of bunion.

The purpose of this study is to analyze the types and characteristics of wedding ceremony robes in the Jeju area from the 1950's to the 1980's. The analysis used 413 wedding pictures. The results of the study are as follows: 1. The following are the propotion of robe types used wedding ceremonies. 1.0% of Danryeong & Jangot, 6.5% of Danryeong & Wonsam, 1.5% of Danryeong & Chima+Jegori, 2.7% of Durumaki & Chima+Jegori, 24.7% of suit & Chima+Jegori and 63.7% of suit & wedding dress from the 1950's to the 1980's. 2. The Korean-style robes gradually decreased from the 1950's, and disappeared in the 1970's. The Chima+Jegori was introduced in the 1950's, reached its peak in the 1960's and its popularity continued to the 1970's. In the 1980's, after the Korean-style robes disappeared, the western ceremony robes were used in all the ceremonies. 3. After the Western-style robes, in which a bride wears a wedding dress, was introduced in the 1960's, its usage rapidly increased in the 1970's and is still popular today.

The purpose of this study was to research of the symbolic meaning. of religious habit in the Korean Catholic Women's Religious Society. The research was carried out by investigating a wide range of document including those on museum of religious society, follow by considering the questionnaire and interviews on the habit. The results were as follow. The action and ceremony relation to religious habit should be expressive of evidence of Jesus, poverty and modesty, protect from external temptation, married with Jesus. External form of the religious habits should be expressive of Vergin Mary, bride of Jesus, york of Jesus, the Sacrament, atonement, innocenc, eternity, confirm one's determination, poverty, rasario, adversity. Symbolic meaning in external form of the religious habit was expressed more definitly, varietly than action and ceremony relation to religious habit by well designed item, detail, color and accessory of habits. All over the world religious societies allowing ordinary clothes but most korean women's religious societies still hold on religious habit. Present style is very simplyfied than the traditional one. But many religious societies make efforts for keeping the symbolic meaning of religious habit.

This study firstly identify the characteristics of the clothes for traditional wedding ceremony from the late Chosun Dynasty (19th Century) and today through comparison. It also tries to discover what today's people are incorrectly aware of regarding the traditional wedding clothes particularly by survey. It ultimately aims to present constructive ways of solution against the illadvised and simplified deformation of the traditional wedding clothes. When comparing the traditional wedding clothes from the late Chosun and its modern counterparts, Dan-ryung and Samo-kwandae is still used for bridegroom's dress. In case of bride's dress, several items such as Yeom-eui, So-eui and Hwal-ot have been disappeared while Won-sam can be seen today. There were found many additional differences not only in type of the wedding clothes, but also in its form and constitution. Therefore, it is advisory to take the wedding clothes worn by commoners and upper class as the basic form for today's traditional wedding clothes. In addition, diversified research should be carried on to make them broadly accepted by today's life.

We proposed the bridge type fault current limiter(FCL) using switching operation of high-Tc superconducting(HTSC) thin film. The proposed bridge type FCL consists of HTSC thin film, a diode bridge and a dc reactor. The controller for the operation of an interrupter is required in the conventional bridge type FCL to prevent the continuous increase of fault current after a fault happens. On the other hand, the proposed bridge type FCL can limit the fault current without the interrupter and the controller for its operation by the resistance generated when the gradually increased fault current exceeds HTSC thin film's critical current. We calculated the time when the gradually increased fault current started to be limited by the resistance generated in HTSC thin film after a fault happened and confirmed that it could be dependent on the amplitude of source voltage. The experimental results well agreed with the calculated ones from simulation.

The purpose of this study was to examine how much the cost of marriage ceremony has increased according to the economic growth. The relationship between marriage expenditures and other comparison variables such as per capital GNP, monthly income, consumer price index was particularly examined. All the money values were adjusted by consumer price index. Data from the Central Committee for Promotion of Saving were used in this study. The results of this study follow. First, nominal and actual total outlay of marriage ceremony has continuously increased. Total marriage ceremony cost was positively correlated with the housing price so that bridegroom’s outlay were greater than that of bride’s one since bridegroom was more likely to have the responsibility for the price of new couple’s house. Second, it was found that increased percentage rate of marriage ceremony cost was greater than that of national economic growth. The total marriage expenditure was about 10 times as much per capital income in 1990. Third, it was revealed that housing cost increased three times from 1990 to 1995, and marriage ceremony expense was accordingly increased twice during the same periods. Such trends tend to increase continuously. Last, the marriage cost percentage to monthly income called marriage expenditure share increased by 1990 and then decreased. Such a decreasing trend can be explained by the increased amount of income partly due to the higher wage rate compared to other conditions since 1990.
