For an off-site consequence analysis at nuclear power plant, MELCOR Accident Consequence Code System(MACCS) II code is widely used as a software tool. In this study, the algorithm of web-based off-site consequence analysis program(OSCAP) using the MACCS II code was developed for an Integrated Leak Rate Test (ILRT) interval extension and Level 3 probabilistic safety assessment(PSA), and verification and validation(V&V) of the program was performed. The main input data for the MACCS II code are meteorological, population distribution and source term information. However, it requires lots of time and efforts to generate the main input data for an off-site consequence analysis using the MACCS II code. For example, the meteorological data are collected from each nuclear power site in real time, but the formats of the raw data collected are different from each site. To reduce the efforts and time for risk assessments, the web-based OSCAP has an automatic processing module which converts the format of the raw data collected from each site to the input data format of the MACCS II code. The program also provides an automatic function of converting the latest population data from Statistics Korea, the National Statistical Office, to the population distribution input data format of the MACCS II code. For the source term data, the program includes the release fraction of each source term category resulting from modular accident analysis program(MAAP) code analysis and the core inventory data from ORIGEN. These analysis results of each plant in Korea are stored in a database module of the web-based OSCAP, so the user can select the defaulted source term data of each plant without handling source term input data.

사회가 복잡해지고 첨단 사회로 갈수록 저작권 침해 사례는 증가하고 있다고 볼 수 있다. 소프트웨어 저작권 분쟁 중에는 소프트웨어가 복제되어 업그레이드 소프트웨어로 만들어 졌는지 판단에 대한 분쟁이 있을 수 있다. 본 논문에서는 소프트웨어 업그레이드 여부에 판정에 대한 분석 방법을 제안하고자 한다. 소프트웨어 업그레이드 분석을 위하여 소프트웨어 동일 유사성 분석 기법을 이용하였다. 분석 대상 프로그램은 서버, 관리 프로그램, 라즈베리 PC 프로그램들을 대상한다. 첫번째 분석은 프로그램들의 생성 정보와 내용의 일치성을 확인한다. 그리고 제출된 프로그램과 현장에 설치된 프로그램간의 기능과 화면 구성에 대한 유사성 여부를 분석한다. 두 번째 비교 분석은 동일한 환경에서 두 개의 프로그램을 동작을 시켜 유사성을 비교 분석한다. 비교 분석 결과 2 개의 프로그램은 동작과 구성화면이 동일함을 확인되었다. 그리로 한 몇 개의 파일에서 사소한 차이는 발견되었으나 2개 프로그램은 대부분 동일하거나 거의 유사한 소스 코드를 이용하여 제작된 것을 확인하였다. 따라서 본 프로그램은 업그레이드 프로그램으로 판정 할 수 있다.

This paper has been studied to evaluate the program educational objectives (PEO) for mechanical engineering program at Chosun University. The program educational objectives were set up the educational goals with relationof college educational objectives and ability or quality of engineers after 3 years of graduation, and educated the basic competance of engineers are the equipments of high-level education enviroments, faculty and curriculum for effective engineering educations. This paper were to announce PEO to current students, to establish and to improve PEO throughout accesment and analysis of PEO evaluation. The improvement and documentation of PEO accesement system, collecton and analysis of PEO were conducted industial surveys for engineers graduated this program. The results are served as a substantial basis for setting furture educational goals, renewed PEO by the closed loop and making decision for quality of engineering education in the college of engineering. This study would be comfined measurements, analysis and achievements of PEO for graduated engineers in this program.

When evaluating effectiveness of a R&D program, there is a tendency to simply compare the performances of the beneficiaries before and after the program or to compare the differences in the performances of the beneficiaries and the non-beneficiaries before-after the program. However, these ways of evaluating effectiveness of a program have some problems because they can not differentiate between complement effect, which facilitates corporate R&D investment, and substitute effect, which, literally, substitutes corporate R&D investment. Therefore, these problems could bring about wrong policies concerning R&D programs. In this paper, a new approach using path analysis is suggested as a means to overcome these problems and it is utilized, as an application, to evaluate the effectiveness of Plant Engineering Program conducted by Ministry of Trade, Industry & Energy, Korea. First, the direct impact of government R&D investment on corporate R&D investment is analyzed, through which it is identified which of crowding-in effect (complement effect) and crowding-out effect (substitute effect) is dominant. Next, the direct effect of government R&D investment on corporate performance and the direct effect of corporate R&D investment on corporate performance is analyzed respectively. Finally, by combining the two previous analysis, the total effect of government R&D investment on corporate performance is identified. As a result, it turns out that, in Plant Engineering Program, crowding-in effect is more dominant than crowding-out effect and that Plant Engineering Program has definitely positive effect on the beneficiary in terms of corporate performance indirectly and directly.

To develop a reliability analysis program applied to the diagnosis for air operated valve's integrity. we collected, analyzed AOV failure data from foreign and domestic nuclear power plants, and classified whole subjects of this program into several groups according to type and size. We established a theoretical basis using Lognormal Distribution and Bayesian Theory to develop analysis methodology. The result of this program was applied to the calculation of operational unavailability of AOV, and the effect of AOV's failure. Also this program can be applied to the development of diagnostic technique considering AOV environment (temperature, pressure), and setting-up maintenance cycle.

Railroad track consists of relatively simple structures such as rail, sleeper, ballast. Roadbed shares vertical pressure by train load which passed through rail to ballast as base that supports the track. For evaluating stress and displacement of roadbed due to the railroad load is an important role on the track as a basic data for estimation of the durability and design of the roadbed thickness. GEOTRACK program applied multi-layered theory was developed for analyzing railroad track structure. GEOTRACK program is a sort of numerical analysis program which has advantage that can analysis component of track by simple method. In this study, this program was used to preform the numerical analysis by changing track conditions and roadbed conditions such as tie, reinforced roadbed, dynamic wheel load, Resilient modulus and so on. Further detail will be presented on the paper.

The finite element programs have been developed for structure, collision, flow, dynamics, heat transfer, acoustics, electromagnetism, MEMS (Micro Electro Mechanical Systems), and etc. These programs can be classified as either "package" program or "single purpose" program. Single purpose programs usually have convenient and powerful functions, but these programs have limited expandability to different fields of analysis. Therefore, the method to converter the analysis results of single purpose program to other programs is needed. In the research, multi-body data conversion methods of 1) finite element model and 2) solid model were created to convert fluid analysis result of CFD-ACE+ to ANSYS data structure. Automatic boundary condition algorithms were developed for blade, and finite element model was compared with solid model. It is expected that, by sealess data transfer, the Multi-body Data Conversion Program could reduce the development period of torque converters.
