  • Helicobasidium mompa Tanaka and Resellinia necatrix Prillieux cause violet root rot and white root rot of various crops, respectively. Intensive cultural practices, such as the use of dwarf stock, glasshouse cultivation, etc., predispose plants to the diseases. The diseases can be controlled only by biennial drench of 50100L of chemicals for each tree. Biocontrol with soil microorganisms proved ineffective under field conditions. Long-term control may be hampered by the perennial growth of hosts and by the difficulty in the establishment of antagonists in soil. Crop rotation or soil amendment is not applicable, either. Fungal viruses with dsRNA genome (Buck 1986) are promising against root diseases of fruit trees since they exist within the cytoplasm of fungal hyphae and need no effort to help them persist in the field. The viruses are considered to spread though the network of fungal mycelia in the soil once they enter the fungal cytoplasm. Here, we present preliminary results from a project to control the root diseases of fruit trees with dsRNA.(중략)

  • Recently, interests in IT Service Management(ITSM) are increasing internationally as well as domestically. In order to realize the benefits from ITSM, it is necessary to institutionalize it as a culture of the organization through effective change management. One of the most promising approach of effective change management is the change management framework of ITSM. In this study, we analyze a success case in which the change management framework of ITSM was applied to IT Service company which has introduced ITSM. Through the analyses, this study aims to propose a feasible and specific approach to institutionalize ITSM. To accomplish the objective, the study is designed to analyze specific methods for applying ITSM's change management framework to ITSM organizations, performance of projects and future directions based on interviews and review of project documents/deliverables. This study could not provide detailed performance measures due to lack of previous research on this topic and difficulty of obtaining quantitative data. However, this study has contributed to proposing a direction to institutionalize ITSM in organizations by analyzing a feasibility of ITSM's change management framework in implementing ITSM.

  • The purpose and content of Chonnam National University Center for Science Talented Education program and students' responses were described. The program was developed with the purpose of providing various learning opportunities for science talented students according to the level of their learning abilities. Students are given a variety of activities based on their potentials and interest. The program was developed in four subjects, such as mathematics, information science, science Ⅰ (physics and earth science), and science Ⅱ (biology and chemistry). Each subject consisted of simple inquiry, advanced one, and project, even though it had its own distinctions. Students were selected for each subject based on two criteria, that is, achievements in school science or mathematics (the upper 3 percent of the 8th grade students) and examination scores. Means and standard deviations for each subject were as follows: 51.8 and 13.3 for Science Ⅰ, 53.1 and 13.9 for Science Ⅱ, 36.7 and 10.7 for mathematics and 36.4 and 12.5 for information science. Thirty hours of summer classes were performed, and a survey was administered to obtain students' responses concerning difficulty, interest, teaching and content of the program.

  • Purpose: Many domestic companies have to make out quantitative evaluation table in their proposal when they conduct the software R&D project. However, most of companies have a difficulty to select the evaluation items and criteria, also to derive a quantitative results. Therefore, we propose a method to derive the quantitative evaluation index by utilizing the ISO/IEC 9126-2. Methods: Analyzing ISO/IEC 9126-2, and we classify the quality metrics as high-classification and sub-classification for Web/App software, Embedded software and Installation software. Next, Conduct the metrics selection survey depending on importance and necessity. Then, carry out the case study. Verify the correspondence between evaluation items and criteria from original suggestion of company and from outcome by utilizing the ISO/IEC 9126-2 quality metrics. Results: It is possible to classify into two metrics, one for common software or one another for only special software. Furthermore, there is quality metrics that is more important and more necessary depending upon characteristics of the software. Conclusion: ISO/IEC 9126-2 quality metrics can be used to make an evaluation items and criteria for quantitative evaluation table of software product.

  • The trend of current urban redevelopment and new city development project shows that the superstructure of building is getting larger and higher in consequence of a limited plottage condition and the preference of landmark. For this reason, it is definitely required to extend pile diameter and install the pilein deep foundation to support superstructure. The pile method causes construction-related problems such as increasing quantities, difficulty of storage & transportation material and decreasing design load while construct pile in deep foundation. The Bored Pile method has applied to minimize those problems. As above shown, this article will be presented construction case study of Barrette Pile and R.C.D in order to make a counterproposal for the quality control of a large building foundation work.

  • It is necessary to guarantee the safety, serviceability and durability of reinforced concrete structures over their service life. However, concrete structures represent a decrease in their durability due to the effects of external environments according to the passage of time, and such degradation in durability can cause structural degradation in materials. In concrete structures, some degradations in durability increase the corrosion of embedded rebars and also decrease the structural performance of materials. Thus, the structural condition assessment of RC materials damaged by corrosion of rebars becomes an important factor that judges needs to apply restoration. In order to detect the damage of reinforced concrete structures, a visual inspection, a nondestructive evaluation method(NDE) and a specific loading test have been employed. However, obscurities for visual inspection and inaccessible members raise difficulty in evaluating structure condition. For these reasons, detection of location and quantification of the damage in structures via structural response have been one of the very important topics in system identification research. The main objective of this project is to develope a methodologies for the damage identification via static responses of the members damaged by durability. Six reinforced concrete beams with variables of corrosion position and corrosion width were fabricated and the damage detections of corroded RC beams were performed by the optimization and the conjugate beam methods using static deflection. In results it is proved that the conjugate beam method could predict the damage of RC members practically.

  • This study aims to assess Green-Tourism accessibility of Rural Experience Village and then prepare improvement methods. To do this study, we surveyed 25 operators of Rural Experience Village in Chungbuk. We used 21 issues in all for analysis and the following shows a summary of major results. Rural Experience Village has a generally hard time conducting facility maintenance. Countermeasures for maintenance are required to run smoothly. Since Rural Experience Village has difficulty attracting visitors to the village, countermeasures are needed to attract visitors through business promotion. The results of assessing Green-Tourism accessibility showed us that some villages are a lot more accessible than others. Therefore, it is necessary that there should be improvements of Green-Tourism accessibility by attracting visitors and increasing operating days so that Green-tourism accessibility can be enhanced. In spite of its high level of accessibility since Rural Experience Village belonging to Goesan has low profitability, it is especially imperative that we establish more positive project promotion to cover it.

  • This study compares the main features of the Act of National Contract with the Act of Defense Aquisition Program, which is the only one in Korea for long-term contracts. When applying the progress payments system to the defense R&D project, We can prevent disputes between parties and create a stable development environment through smooth partnerships. Smaller, direct and indirect losses can be alleviated, such as the waste of administrative power required to deal with disputes due to the payment of delayed prizes and restrictions on business activities due to the difficulty of forecasting the results of companies. In large measure, we will be able to procure a high-quality weapon system in a timely manner to support the security of the nation as well as international competitiveness through the growth of our defense industry.
