The purpose of this paper is to study on the spatial characteristics from the "The Holy Trinity" fresco painted by Masaccio in the early Renaissance paintings. The results of this study are as follows. 1. The elevation composition of the "The Holy Trinity" fresco is divided into the upper and lower structure through horizontal axis on horizontal line around vanishing point. The upper structure is composed of vertical axis formed through the disposition of the "Trinity" elements and horizontal axis on horizontal line. The lower structure is composed of the sarcophagus and skeleton in such inside and the altar supported through circular columns of left and right. 2. The section composition of the "The Holy Trinity" fresco is composed of the ceiling structure of cylindrical-shaped vault on upper part around basic square floor plan that is interior space and upper structure. The exterior space and lower structure is placed with sarcophagus in inner part that altar and step is projected as same height and width in the outside direction. 3. The basic floor composition of the "The Holy Trinity" fresco is planned by square shape around structural columns that is placed at corners as symmetry through transverse, longitudinal and diagonal axis. The whole floor composition planned through the altar and step that is in exterior space at front, the apse of round form at rear part and the structure of the middle story concept at interior. 4. The visual aspect of the "The Holy Trinity" fresco is composed of the stable balance in relation with distance and height because the interior and exterior space as well as the upper structure and lower structure is formed by regular proportion system. The elevation angle of visual range was planned to view in detail generally or partially the architectural composition system and element, characters through proper visual distance, center and position.

This study is about the costume depicted upon the fraction of fresco which was excavated from Kumseong-li, Hwadae-Gun, Hamkyungbuk-Do, North Korea in 2004. According to the characteristics of its relics, this tomb was reported to belong to Parhae Dynasty(698-926). The fraction of fresco only shows below part of the knees of a man. A light red colored robe reaches down to his ankles on the back, whereas front part of it looks tucked up, which is likely to have slits on both side seams. Although tightly wrapped shins were reported as a pair of gaiters, there is no decisive evidence on the fresco. I suggest another possibility that this man wore slim pants. Also in order to figure out if these shins are considered as gaiters, I proceed comparative research on the historical sources about gaiters of countries and eras adjacent to Parhae. Consequently the idea that people of Parhae might have used gaiters turned out to be acceptable. The black boots show rather basic style: the toe tips are not pointed up, boot leg doesn't look either wide or long. These boots can not be identified with Ammohwa(暗摸靴) which the envoy Yang(楊) gave the protocol Miyakoyoshika(都良香) at his official visit to Japan, because Ammohwa has not yet been properly defined.

Cave 79 of Kumtura grottoes, is the best preserved cave, which has an important meaning for research on Uighur costume. This paper is intended to analyze the costume characteristics of female donors in Cave 79 by comparing image materials between Dunhuang murals and other murals in Xinjiang province. In Cave 79, female donor wears red robe with tight sleeve, whose collar is crescent-shaped decorated. Two different opinions are upheld for this decoration. One regards this as the turn-down collar, while the other believes this as decoration on V-neckline. Red robe is quite common in female donors of Xinjiang and Dunhuang murals and a female in fresco is wearing a crown in a triangle red headwear style, regarded as red silk and drooping at head. Female donors wear an extra coat, kame hair clasp, red jacket, light-colored high-waist skirt with a long-tail waistband, and tangerine Pibo (silk ribbon) with scattered small flowers. All these costume styles are commonly-used by Han females. The kame headwear is also the common ornament for Han females and the female's hairstyle is in cone shape on head by a white kame. Current costumes are similar but not completely same.

Currently, the electro-hydraulic servo loading control system manufactured by MTS, OpenFresco hybrid test interface software and OpenSees finite element software are widely used in structure laboratories to carry out hybrid test, but there is no relevant public information about full structure pseudo-dynamic test based on the above software and hardware. In order to study the feasibility of using the above software and hardware to carry out full structure pseudo-dynamic test, the full structure pseudo-dynamic virtual experiments of a single degree of freedom (SDOF) structure and a two degrees of freedom (2DOFs) structure are carried out based on the MTS 793 Demo Mode, and the results are respectively compared with the finite element analysis method. The results show that the finite element analysis results and full structure pseudo-dynamic virtual experiment results are highly consistent, which verifies the feasibility of carrying out the full structure pseudo-dynamic test based on the above software and hardware. Then, a three story steel frame full structure pseudo-dynamic test is conducted, and the smooth implementation of full structure pseudo-dynamic test of the three story steel frame further verifies the reliability of thistesting method. The implementation method of carrying out the full structure pseudo-dynamic tests are introduced in detail, which can provide some reference for relevant research.

When restoring a tomb of Songeun, Park Ik that damaged by typhoon in Kobubri, Chungdomyon, Mill Yang, Kyoung Nam in October 2000, a flower designed stone and fresco was discovered. Soneun Park Ik passed the civil service examination in Kongmin dynasty and was consecutively occupied Sajaedogam(司宰少監; regarded as one of second highest official rank). The fresco realistically depicts custom of ordinary people in end of Koryo, beginning of Chosun dynasty that it is considered as an important research material in study of ostumes. Therefore, this research intend to contribute to study of costumes in general public of Koryo that has insufficient study materials through study and analyze of costumes in the fresco with literature research. The number of figures in the fresco is presumed as 26-27 in all but clearly observed figures is only five women and four men and partly damaged figures are two men and two women. Women are worn relatively long yoo that can cover hip as an upper garment and Sang(裳) as trousers. The upper garments are all adjusted to right and has Jikryoung gik (straight collars) but there are strip attached collars or double collars among the Jikryoung gik. The length of Sang reaches to ankle and a waistband is trailed to below the knees. Most of hair are combed in the two sides and made a ring, moreover worn ceremonial coronet, which imply the ceremonial parade. Distinguished from the frescos of Koguryo, there are no women wearing Po(袍) also Yoo with Dae(帶) and without were coexisted. The mens costume is mainly appeared in two types. One(元) is Danryoungpo, Po with round collar and wearing a lozenge shaped crest with a brim, the other is Jikryoung Po, Po with straight collar, and wearing Ballib(拔笠), the latter is a costume of two man presumed as envoys. In the case of Danryoungpo, its length reached to ankle that shows decorum and in Jikryoungpo its length is below the knees that seem to offer practicality for envoys to guide a long journey. Both man and women are in decent cloth with a crest, which simple costume for ordinary people as a Chaksoopo that has comfortable length for movement and narrow sleeves. Songeun Park Ik actively worked under regency of One dynasty that influence of Mongol is seen in mans crest. There are some changes but including womens costume most of cloth are followed Korean traditional costume style.

High-strength steel composite Y-eccentrically braced frame (Y-HSS-EBF) is a novel structural system. In this study, the spatial substructure hybrid simulation test (SHST) method is used to further study the seismic performance of Y-HSS-EBF. Firstly, based on the cyclic loading tests of two single-story single-span Y-HSS-EBF planar specimens, a finite element model in OpenSees was verified to provide a reference for the numerical substructure analysis model for the later SHST. Then, the SHST was carried out on the OpenFresco test platform. A three-story spatial Y-HSS-EBF model was taken as the prototype, the top story was taken as the experimental substructure, and the remaining two stories were taken as the numerical substructure to be simulated in OpenSees. According to the test results, the validity of the SHST was verified, and the main seismic performance indexes of the SHST model were analyzed. The results show that, the SHST based on the OpenFresco platform has good stability and accuracy, and the results of the SHST agree well with the global numerical model of the structure. Under strong seismic action, the plastic deformation of Y-HSS-EBF mainly occurs in the shear link, and the beam, beam-columns and braces can basically remain in the elastic state, which is conducive to post-earthquake repair.

In the present study, we focus on the CFD simulations for the performance and the rotor-generated wake of a model-scale wind turbine which was designed for wave tank experiments. The CFD simulations with fully resolved rotor geometry are performed using MARIN's community-based open-source CFD code ReFRESCO. The absolute formulation method (AFM) is leveraged to model the rotating wind turbine. The k - ω SST turbulence model is adopted in the incompressible Reynolds Averaged Navier-Stokes (RANS) simulations. First, the thrust and torque coefficients, C_T and C_P, are calculated at different Tip Speed Ratios (TSR), and the results are compared against the experimental data and previous numerical results. The pressure distribution of the turbine blades at the 70% span is obtained and compared to the results obtained by other tools. Then, a verification study aiming at quantifying the discretization uncertainty of the turbine performance with respect to the grid resolution in the wake region is performed. Last, the rotor-generated wake at the TSR of 7 is presented and discussed.

Journal of the Korean Society of Clothing and Textiles Vol. 21, Nt. 5 (1997) p. 865∼879 The purpose of the study is to identify a historical change about the women's underwear and trousers this nation of ours until an ancient times to modern ages. Because the record of the women's trousers exist scarcely anything, the study refers to several documents, for example, the literatures of the Chinese and the Chosun Dynasty, the Koryu's fresco, the Tou of Shinra, the painting of the rock face, the archaeological dresses and genre pictures, and The folkways methods through the residents is used to collect and to arrange of an enlightened age and modern times. Originally, the women's trousers appeared for the nomadism and the hunting in the northern distric and the northeastern provinces. Male and female, old and young wear the trousers which are the clothes native to Korea. The trousers which are originally narrow trousers are influnced by Chinese wide trousers. The trousers at the time of Samsuk hand down until Korea. The Skirt on the trousers is nothing but a courtesy. But gradually, it is distinguished only the trousers, and then, there are exchanged an underwear which not only the protection angainst the cold but also the beautiful. Therefore, the form of skirt is diminished, and the underwear is simplified as the increasing status and the activity of woman in the age of civilization. In a way, the reform trousers and Three-kingdom era trousers appeared and the Dansogok and Sogok disappeared at present. There are confirmed in my investigation of folk customs.
