During the six years from 2006 to 2011, based on a study of projects with an area equivalent to or less than $2,700m^2$ located in Jeju self-governing province, it was shown, through comparison with the pre-existing calculation methods, that there were many problems with the application of the standard cost. Accounting for the uniqueness of Jeju province, the study suggested an alternative method for applying the standard cost, basing it on property usage of either urban area or non-urban area pursuant to the National Land Planning and Utilization Act rather than land type of either mountain area or non-mountain area, with the utilization of T-test and ANOVA raising the reliability of this study.

The purpose of this study was to investigate the actual situation of nursing students' exposure to blood and body fluids, and their knowledge, awareness and performance of standard precautions in an attempt to offer basic data for education of nursing students concerning infection control. The participants of this study were 309 juniors and seniors enrolled in the nursing colleges in J province. Of the participants, 71.5% turned out to have experienced exposure to the blood and body fluids of patients. The mean score of the knowledge about standard precautions was $20.59{\pm}2.05$, whereas grade, infection control education were statistically significant. The average awareness of standard precautions scored $4.67{\pm}.36$, and age, no follow-up measures were statistically significant. The mean sore for the performance of standard precautions was $4.25{\pm}.70$, while exposure to blood and body fluids was found to be statistically significant. There was positive correlation between the participants' knowledge, awareness and performance. The awareness(${\beta}=.274$) of standard precautions only stood out significantly among the factors affecting the performance of standard precautions, accounting for 8.6% in the performance variance of standard precautions. The study found it necessary to develop the infection control program in diverse ways by complementing especially the areas which used to show low awareness and performance of standard precautions. It is thus suggested to intensify education for students about infection control prior to starting clinical training.

This study aims to find a proper construction cost calculation method by comparing unit prices of cost estimate in landscape construction among other public ordering construction projects. There were 7 out of 12 items from the actual work cost in the first half of 2011 were compared. The 12 items were classified as landscape Architectural construction and the 7 items were the approximate standard. As applied construction types, the comparable 35 items out of the 80 actual work cost items applied to 5 sites were compared to the unit price of the standard quantity per unit in March 2011, which was the approximate standard. Actual construction rate of the 7 items in the category of landscape sector was 104.86% for each item and 92.09% as a total construction cost. The high actual construction rate was caused by the high rate of seed spray depending on the status of applying rocks. However, there were more fundamental reasons for the cost generated from aslope treatment for grass and seed spray. So, it requires more detailed regulations on the modification factors for each soil type, the standard and needs to improve theillogical standard quantity per unit system. Actual construction rate of the 35 items in the applied sectors of civil engineering and architecture was 78.65% for each item and 71.31% (70.17%) as a total construction cost. This shows that actual unit cost cannot reflect actual cost structurally and standard quantity per unit system lacks practicality in terms of construction due to thelabor force. 85.1~91.2 % actual construction rate announced by the Ministry of Land and Maritime Affairs referred to the newly switched items. So the result was estimated as actual construction rate. This requires supplementation after verification in order to make the actual work cost produce at a proper rate. Also, standard quantity per unit system needs complementation with these actual data and so on.

In this paper the problem of calculating the probability that the responses of a wind-excited structure exceed specified thresholds within a given time interval is considered. The failure domain of the problem can be expressed as a union of elementary failure domains whose boundaries are of quadratic form. The Domain Decomposition Method (DDM) is employed, after being appropriately extended, to solve this problem. The probability estimate of the overall failure domain is given by the sum of the probabilities of the elementary failure domains multiplied by a reduction factor accounting for the overlapping degree of the different elementary failure domains. The DDM is extended with the help of Line Sampling (LS), from its original presentation where the boundary of the elementary failure domains are of linear form, to the current case involving quadratic elementary failure domains. An example involving an along-wind excited steel building shows the accuracy and efficiency of the proposed methodology as compared with that obtained using standard Monte Carlo simulations (MCS).

This paper compares long-run buy-and-hold returns of privatization initial public offerings to those of domestic stock markets of respective countries using a sample of 29 privatized telecom initial public offerings from 27 countries. The evidence indicates that the privatization IPOs significantly outperform their domestic stock markets if the returns are equally-weighted while they do not outperform the markets if value-weighted. In addition, this paper analyzes the cross-sectional determinants of long-run buy-and- hold returns of privatized telecom shares. The results indicate that the long-run performance of privatized telecom IPOs is moderately related to the proxies of policy uncertainty or systematic risk while the size of the firm and some market wide variables such as the accounting standard, origin of commercial law, and the corporate governance scheme significantly affect the stock performance of privatized telecom shares.

The direct strength method adopted by the AISI Standard and AS/NZS 4600 is an advanced design method meant to substitute the effective width method for the design of cold-formed steel structural members accounting for local instability of thin plate elements. It was proven that the design strength formula for the direct strength method could predict the ultimate strength of medium strength steel welded section compressive and flexural members with local buckling reasonably. This paper focuses on the modification of the direct strength formula for the application to high strength and high performance steel welded section columns which have the nominal yield stress higher than 460 MPa and undergo local buckling, overall buckling or their interaction. The resistance of high strength steel welded H and Box section columns calculated by the proposed direct strength formulae were validated by comparison with various compression test results, FE results, and predictions by existing specifications.

Business diversification is inevitable to survive under the current competitive business environments. The advent of new businesses makes corporate governance more complicated through corporate combinations. Recent introduction of new accounting standard, International Financial Reporting Standards(IFRS), accelerates the need for corporate governance analysis. This study analyses the complex corporate governance system and its relation to the business performance using social network analysis. Corporate inter-governance networks can be visualized easily in a social network diagram. 552 corporate governance data are empirically analysed in the Korean stock market. The changes in In-Degree between networks are positively related with the changes in corporate sales volume. We can find the same results using operating profits as corporate performance proxy. The results show that social network analysis technique can be applied to investments in the stock markets.

Total anomalous pulmonary venous return is a cardiac malformation in which there is no direct connection between any pulmonary vein and the left atrium but, rather all the pulmonary veins connect to the right atrium or one of its tributaries. TAPVC is a relatively uncommon anomaly, accounting for only about 1.5-3% of cases of congenital heart disease. Recently improvement in intraoperative techniques did eventually bring substantial improvements in the results in infants. 4 cases of TAPVC was successfully treated with one-stage operation, in the Dept. of Thoracic and Cardiovascular Surgery, National Medical Center in which 2 cases are supracardiac types and the other 2 cases are cardiac types. Sex ratio was 1:1, and the range of age was 2 years-18 years. The common pulmonary venous sinus was connected to the left vertical vein and innominate vein: in 2 supracardiac types and coronary sinus in 2 cardiac types. All cases are operated with standard cardiopulmonary bypass, and the hospital mortality was 0%.

Present monetary system is based on fallacies. The purpose of this article is to highlight the pitfalls in economic thinking. The article shows that this way of thinking leads to the creation of inflation which is the root of all evil. The analysis proceeds in different approach to the contemporary theory of money. An inflation- free monetary system is introduced. Monetary system is the set of mechanisms that controls money. In this broad sense, monetary system can be divided into three different systems. Each of them has different goal; National monetary system which aims to raise sufficient funds in order to reach an optimal level of output growth that maintains full employment and satisfies the economic requirements of the community. National redistribution system which aims to redistribute funds in order to sustain individuals at or above a specified material standard of living, and enable government to provide public services. International monetary system which aims to preserve rights of parties in foreign exchange transactions.

The coexistence of the superconductivity and magnetism in the Ho1-xDyxNi2B2C is studied by using Ginzburg-Landau theory. This material violates the standard do Gennes scaling showing the coexistence and complex interplay of superconducting and magnetic order yielding an anomalous phase diagram. We propose a phenomenological model which includes two magnetic and two superconducting order parameters accounting for the multi-band structure of this material. We describe the magnetic fluctuations and order and demonstrate that they lead to anomalous behavior of the upper critical field. The doping dependence of Tc in Ho1-xDyxNi2B2C showing a reentrance behavior are analyzed yielding a very good agreement with experimental data.
