A settlement prediction method based on shear wave velocity measurements and soil nonlinearity was recently developed and verified by means of centrifuge tests. However, the method was only applicable to heavily overconsolidated soil deposits under enlarged yield surfaces. In this study, the settlement evaluation method was refined to consider the stress history of the sublayer, based on an overconsolidation ratio evaluation technique, and thereby incorporate irrecoverable plastic deformation in the settlement calculation. A relationship between the small-strain shear modulus and overconsolidation ratio, which can be determined from laboratory tests, was adopted to describe the stress history of the subsurface. Based on the overconsolidation ratio determined, the value of an empirical coefficient that reflects the effect of plastic deformation over the elastic region is determined by comparing the overconsolidation ratio with the stress increment transmitted by the surface design load. The refined method that incorporate this empirical coefficient was successfully validated by means of centrifuge tests, even under normally consolidated loading conditions.

This study summarizes the dissemination aspects of liturgical vestments in Korea, and organizes the value and meanings of these disseminations as it appeared in the history of costumes by carrying out an empirical analysis on the relics of liturgical vestments since the modern times. It also examines its design characteristics as well. Liturgical vestments have symbolic meaning for the purpose and solar term of ceremonial occasions and it also functions as a way to differentiate the position and duty of the clergy. Liturgical vestments developed on the basis of ancient Greek-Roman costumes and transformed each situation and social trend of the age. Korean liturgical vestments started with their traditional costumes, in 1887, it were changed into French(western) style with freedom of religious. After the secondary Vatican Council held in 1962, various regulations were changed to spread the Catholic doctrines and ideology. This study conducted an empirical analysis and design consideration on the 28 relics of modern liturgical vestments on the basis of the foregoing standard and concept. As a result of analysis, relics were investigated as research materials worn by Bishops after 1960s. And design elements are that the relics used materials and ornament of Hanbok with flower patterns and decoration such as letter patterns including 壽(life) 福(luck) 喜(pleasure) as well as Chrysanthemum and Mancaowen design. These transition reflected by amend regulation of Vatican Council II. Accordingly, this data has been confirmed to be important for the history of costumes as it informs what process of changes liturgical vestments spread in Korea went through before they are worn as current appearance.

Samguk Yusa is a important historic record about the dynasties of ancient Korea. It consists of information about the hidden, mythical history, old languages and poems. This historical book has been translated many times since the Liberation of Korea in 1945. However, these books are the result of academic research so we are restricted in our usage of them to understand Korean history. There are many historical documentaries and TV series on Samguk Yusa. However, these programs can be viewed only and not be utilized in any way by the audience. Since the computer was introduced to the public, multimedia technology has been a good source to combine text, image, moving picture, sound, animation and graphic. Producing the CD-ROM about historical books not only produce digital images but also a valuable high quality digital information. Digitalization process also keeps the original content of the historical books as well as provide value as a research material as historical, artistic and archaeological item. Furthermore, its information would be provided through a network, like internet, to share and to promote more advanced studies. The purpose of this study is to produce the basic method of multimedia design of Samguk Yusa. This study also researches the problems of multimedia process for more effective usage.

Negative perceptions about corporate social responsibility (CSR) crises and repeated crises are increasing. It is necessary to examine the effects of a proactive strategy of disclosing crisis information against the negative perceptions. The research is intended to analyze ability-based trust, and benevolence-based trust by crisis type, crisis history, and timing of crisis disclosure. In this regard, a 2 (crisis history: present vs. absent) x 2 (crisis type: corporate ability crisis vs CSR crisis) x 2 (timing of crisis disclosure: stealing thunder vs thunder) between-groups design experiment was conducted. Research results show crisis type and crisis history have significant interaction effects on ability-based trust. In the CSR crisis, the case with crisis history shows lower ability-based trust than the case without crisis history. Timing of crisis disclosure showed significant interactions with crisis history and crisis type. The stealing thunder strategy heigntened ability-based trust and benevolence-based trust against the CSR crises and the cases without crisis history more than the corporate ability crises and the cases with crisis history. Considering that the stealing thunder strategy is more effective with the CSR crises than the corporate ability crises, the research results suggest that future CSR crisis responses should prepare active disclosure of crisis information before news media disclosure of such information.

The use of Buckling Restrained Braces (BRB) for enhancing the performance of the buildings is gaining wider acceptance. This paper presents the first application of these devices in a major high-rise building in the Philippines. A 50-storey residential reinforced concrete building tower, with ductile core wall, with BRB system is investigated. The detailed modeling and design procedure of buckling restrained brace system is presented for the optimal design against the two distinct levels of earthquake ground motions; serviceable behavior for frequent earthquakes and very low probability of collapse under extremely rare earthquakes. The stiffness and strength of the buckling restrained brace system are adjusted to optimize the performance of the structural system under different levels of earthquakes. Response spectrum analysis is conducted for Design Basis Earthquake level and Service level, while nonlinear time history analysis is performed for the most credible earthquake. The case study results show the effectiveness of buckling restrained braces.

In recent years, time history analysis has been the method generally used for the seismic analysis of tall buildings with damping devices. When T is the natural period of the first vibration mode of the structure, the sum of the spectral acceleration of the earthquake ground motion is usually adjusted to that of the design response spectrum in the period ranging from 0.2T to 1.5T to meet the requirements of design code. However, when the ground motion is scaled according to the design code, the differences in the responses obtained by response spectrum analysis (RSA) and time history analysis (THA) of the structures increase as the natural period of the structure becomes longer. When time history analysis is performed by using ground accelerations that are scaled according to the design code, base shear is similar to that obtained from RSA, but other responses, such as displacements, drifts and member forces, are underestimated compared to RSA. If these results are adjusted by multiplying with the scale-up factor, the scaled responses become much smaller. Therefore, a scaling method of ground motions corresponding with the design code is proposed in this study, as a way of assisting structural engineers in generating artificial ground motions.

This paper proposes a method for improving a branch predictor for the extendable instruction set computer (EISC) processor. The original EISC branch predictor has several shortcomings: a small branch target buffer, absence of a global history, a one-bit local branch history, and unsupported prediction of branches following LERI, which is a special instruction to extend an immediate value. We adopt a G-share branch predictor and eliminate the existing shortcomings. We verified the new branch predictor on a field-programmable gate array with the Dhrystone benchmark. The newly proposed EISC branch predictor also accomplishes higher branch prediction accuracy than a conventional branch predictor.
