Korean contractors have been maintained sustainable growth since entering into overseas construction market for the first time in 1960' s. In 2010, Korean contractors ordered 761 billion (USD) from overseas markets. Especially, billion (USD) were earned by Korean contractors in overseas plant construction market which account for more than 80% of the total amount by Korean contractors. Nevertheless, many Korean contractors are suffering from lack of technological competitiveness and construction management skills in the design phase compared with global leading contractors. These conditions have directly effect on the success of projects in terms of cost, duration, and quality. So, this study focused on identifying the risk factors and developing risk priority method for the design phase of LNG plant projects whose market is expanding. Research procedures were conducted by the following three steps. First, total 57 risk factors were identified in design phase through extensive literature reviews and experts survey. Second, the authors developed risk priority method which are more suitable for design phase of LNG plant projects by using three criteria, Probability(P), Impact(I), and Coordination Index(CI). Finally, the suitability of risk priority method and practical applicability were verified through expert survey and interview. Consequently, if korean contractors use the suggested risk factors and priority method based on their own know-how and experiences, then more reasonable and rational risk management will be conducted in the design phase of LNG plant projects.

The purpose of this study was to find the effects of guava leaf powder as a natural tenderizing ingredient for low-fat pork seasoned with meat sauce, and to promote a consumer demand and practical use of low-fat pork. Moisture content, pH, color, texture, and sensory tests (quantitative descriptive sensory evaluations and acceptance) were conducted to the control and 5 samples of pork seasoned with 0.75, 1, 1.5, 2, 3% guava leaf powder) to determine the highest effectiveness on tenderizing pork. Moisture content and pH values were the highest in the samples with 1% and 1.5% of guava leaf powder added. L-value of cooked meat decreased, while a-value increased. In the texture test, most of the experiments showed the best values in the sample with 1.5% added. Based on quantitative descriptive sensory evaluations, the unpleasant smell of meat tended to decrease with more guava leaf powder, and the scores of the others were highest in the sample with 1.5% added. This sample also got the highest score in the acceptance test. These results can be used as primary data for research on the tenderizing effect of a functional ingredient and solutions to unbalanced consumption of pork.

This study was conducted to seek improvements by correcting problems of the qualification system of theatrical art technicians, which has a relatively weak foundation, compared to other national industrial qualifications. Through the previous researches, this study attempted to seek main issues and development plans in the field of theatrical art technology, while carrying out in-depth interviews for theatrical art technicians. With the results of this study, problems of the existing system can be largely divided into two kinds. Firstly, the existing system is mostly focused on performance places, especially large-sized public performance halls. Secondly, as a problem in terms of management, the existing system has non-professional management subjects and non-convenience regarding the number of qualification tests and places only in Seoul and once a year. This study grasped problems based on practical demands of the related industry through in-depth interviews with experts, thus seeking proper solutions. What matters most is that the present system should be converted from performance place-centered management to performance-centered management. In other words, by expanding qualification-acquired experts into all the performances, the system should practically contribute to improving the quality of performances and expanding the treatment of experts, which is the fundamental purpose of this system. Moreover, it is needed to seek a plan to expand the convenience of applicants for the procedures and methods of acquiring qualifications.

A preliminary study on the existing attraction effect and compromise effect was started on the experiment studies about product or service and conducted on the empirical studies on things, research trips, staff recruitment process in the research and the actual US presidential election. However most studies have been limited in the theories of the frequency range and no research about combining compromise effect and attraction effect with the types of promotion. The purpose of this study verifies that how attraction effect and compromise effect in the choice option of the choice process for brand varies according to the types of promotion. This study compares the difference of choice of brand between the influence of the attraction effect and compromise effect. The independent variables among the manipulated variables are as follows : (1) Brand choice (attraction effect and compromise effect), (2) Promotion Type (price promotion/non-price promotion). This study was manipulated in between-subjects design and within-subjects design. The results of this study will be able to see the implications for the positioning strategy of offering several new products such as practical dimensions of promotion strategy because the entry of new brands rather increases market share of similar existing brands.

For the last few decades, forest resources in Korea have continuously increased in terms of their stocks. However, due to the low profitability of timber harvesting in Korea, their economic values have not been well recognized. Furthermore, their economic values have not been counted in national statistics associated with forest resources such as the Forestry Household Economy Survey or the National Accounting. This research fundamentally aimed at building a forest valuation system or a procedure that enables one to evaluate the national-level economic values of timber assets in Korea. For this research, it is necessarily required to understand the principles of appraisal methods and any issues raised in their practical applications. Thus, a comprehensive review of appraisal methods utilized in Korea and other countries was conducted in this research. Also, the current valuation system of the National Forests in Korea was investigated. Through the review and the investigation, it was found that an alternative consists of two appraisal methods, the 'Capitalized Income Value' method adopting the Internal Rate of Return (IRR) for the below-rotation age forest and the 'Derived Residual Value' method for the above-rotation age forest, could be the most acceptable for evaluating timber assets of forestry households derived from the Forestry Household Economy Survey in Korea.

The architectural drawing, construction project specification, etc. are included in the contract of a documents. However, construction project specification, for being documentation, is not utilized to such an extent. The reason is that specification information is difficult in collecting information in relation to the architectural drawing, material finishing list and other architectural information. Therefore, an integrated model, which can be associated with other architectural information, is needed, and a DB based on this integrated model must be established in order for it to be utilized in design, construction, and management. The DB, which is established through this process, must be updated according to modification in design, and construction. Furthermore the specification must be in document on the web for reference. Consequently in this research, the structure of integrated model has been introduced, and it has made the search and preparation of the integrated model on the Internet, using the specification information DB established for the mutual reference of DB, possible. The improvements of construction project specification standards are expected by this system. Also, it will bring about Improvements upon claim prevention, and design, construction, management qualities. Furthermore, it will make the use of information more convenient in practical business such as order agency, design service and building site.

In Korea, BIM technology is applied mainly to building construction projects, but is expected to be applied rapidly to civil engineering projects because the government is currently considering the mandatory application of BIM for infrastructure facilities. Because the infrastructure project is processed in a horizontal work area, the application of BIM technology is more useful in the schedule management of the construction phase than the interference management of the design phase. The 4D CAD system is a typical BIM technology applied to the schedule management in the construction phase, but the application to the actual project is limited due to the lack of practical functions. This study examined the functions of four representative 4D CAD systems commercialized so that the selection criterion can be provided according to the characteristics of the project, and suggests that the functions that should be improved to have practicability. As a result of functional analysis, the application characteristics of each system were analyzed and the user convenience was suggested. In addition, a linear 4D simulation methodology was developed to improve the functions applicable to civil engineering projects, and ways to improve the utilization of the infrastructure projects as the construction phase BIM were suggested. In railway and road construction projects, most activities, such as earthwork, bridges, and tunnels proceed along the distance axis in a horizontal space. Therefore, a linear 4D simulation method, in which an activity is expressed along a distance axis, can be more practically useful rather than a simple 4D simulation method with a Gantt chart.
