Currently, there are two major problems in professional engineer(PE) licensure system in Korea to be accredited internationally. One is a incompleteness of system connecting the licensure and the accredited engineering education program and the other one is a insufficient working experience condition required for achieving PE license. Therefore, these two problems are setbacks hindering Korea's PE license accredited internationally. In this study, international tendency stream on mutual accreditation of PE license are reviewed first, and the PE licensure system of the major countries are compared and analyzed. Based on the results, requirements improvement plan are suggested and the gradual implementation method are suggested also.

This paper presents a novel educational model of subjects of electric, electronic and control for marine engineer in accordance with STCW 2010 amendments. In accordance with STCW 2010, contents of such courses in marine engineering operations of undergraduate programs in maritime university should be updated correspondingly to new features. In order to propose the model, this paper analyses and reviews subjects on electric, electronic and control in STCW convention compared to STCW 1995. Also, in this paper, subjects of electric, electronic and control in marine engineering operations in Korea and other countries are analyzed and a new educational model is proposed. in theoretical perspective and practical perspective.

Earthen mass located beneth a sloping group surface, whether natural or manmade, have a tendency to move downward and outward under the influence of gravity. Unless this tendency is suitably counteracted by the Shearing resistances within the mass, a landslide occurs. Avoiding such instabilities is a major concern of the geotechnical engineer. The shearing behavior of a soil is determined empirically, i.e., by field tests or laboratory tests. This results are applied to the slope stability analysis. The factor of safety for slope stability analysis is much more sensitive to the choice of strength parameters as interpreted from soil tests than to the choice of the computational method of analysis. This paper was investigated the influence of the change in the factor of safety due to a change in one of the parameters, relative to the total change in the factor of safety due to change in all parameters. A conclusion may be reached with respect to the required precision definition of the different variables to limit uncertainties in the factor of safety to tolerable levels.

A automatic production system was developed for high productivity and safety. The semi-progressive die was unfavorable for more productivity, safety, material extravagance and incongruent high-speed production. Developed progressive die is suitable for the high production and guarantee triple production by acceptance of three array type for automobile adjust plate. We adopt Pro-$Engineer{\circledr}$ for three dimensional computer aided design suitable for the disassembly and assembly evaluation. The conclusion of this study is as follow. First, press die parts solid modeling system is built by using Pro-$Engineer{\circledr}$ through this research and verified allowable tolerance and possibility of assembly and disassembly of parts. Therefore we can reduce die manufacturing time and cost. Second, We produce 1000 units pet hot coil 1ton by traditional method, but we can acomplish material saving effect about 12% as 120 units in case of new progressive die. Fourth, we acomplished manufacturing cost curtailment effect more than 20% in comparison with traditional method.

The aim of onboard training of apprentice engineers in the training ship is to support and enhance fundamental knowledge and ability to have both theoretical and practical skills. This diversity in education and training improve the capability to handle problems in a crisis and build-up the feeling of confidence so they can effectively accomplish their assigned tasks in special circumstance like those onboard. Therefore this study suggests some remedies for qualitative improvement and guidance of onboard training ship for apprentice engineers to achieve the aims of onboard training to foster talented marine engineer officers with professional knowledge and leadership.

Nowadays, our industries and occupation are increased under the economy development of government. So, this paper introduce to compare with coefficient's of correlation on the time series of the education and the qualification in our country. For this reason, the decision making to qualifications' foresight which will be change to the education category-prospective on the time series. The qualification has claasified 5 degrees-master craftsman, professional engineer, engineer, technician(or industrial engineer), craftsman - and 516 qualification items. Education has classified to 4 degrees(7 degrees) - elementary, middle, high, high scholastic level school(college, university, graduation). This paper has matched to educational classification and qualification classification through the following method. We defined the same level between education and qualification after analysed correlation under the time series, so the craftsman equals high school graduation people, technician equals college graduation people, engineer quals university graduation people, now we could not analyse master and professional levels. This paper will suggest to the qualification's future policy direction and improve the education policy direction.

Nonlinear analysis for seismic performance evaluation of existing building usually takes 4~5 times more than linear analysis based on KBC code. To obtain accurate results from the nonlinear analysis, there are a lot of things to be considered for nonlinear analysis modeling. For example, reinforcing layout, applied load and seismic details affect behavior of structural members for the existing building. Engineer-oriented computerized system was developed for engineers to evaluate effective seismic performance of existing buildings with abiding by seismic design principles. Using the engineer-oriented program, seismic performance evaluation of reinforced concrete building was performed. Nonlinear hinge properties were applied with real time multiple consideration such as section layout, section analysis result, applied load and performance levels. As a result, the building was evaluated to satisfy LS(Life Safety) performance level. A comparison between engineer-oriented and program-oriented results is presented to show how important the role of structural engineer is for seismic performance evaluation of existing buildings.

As shown in the accident analysis from 2007, it has been found that causes of accidents on large-scale projects are different from those found in general construction projects. A 300-question survey regarding systematic and practical aspects of safety problems at construction sites was distributed to ten (10) different companies. Participants were to respond subjectively, so that the results could be used to assemble the first formal questionnaire survey. They were collected and compiled by an advisory committee for this study. The resulting surveys were then sent to the division chiefs of the top 100 construction companies in Korea, in order to improve the response rate. The Department of Safety & Health Direction, and the :Ministry of Labor, ROK sent the same sheets to medium and small construction companies that placed within 101-200th of all Korea construction companies. The above safety engineers were classified into four (4) levels, from 1st to 4th, followed by the project dollar amount and risk level. Formulae were developed to assign safety engineers to construction sites by engineer level, the project dollar amount, and the project risk level. Conclusions are summarized as follows: 1) Reviewing the assignment system of experienced safety engineers to large scaled projects - The more experienced the engineers assigned to a project, the higher the level of accident prevention. 2) Enforcing the assignment of advanced level safety engineers to large-scaled sites - At least one advanced-level safety engineer should be assigned to construction sites with projects valued at $15million USD (15,000,000,000). 3) For assigning safety engineers by risk level - Twenty models have been developed to calculate the number of safety engineers to be assigned by risk level. In the future, risk level for each job should be established by the government (as is now the practice in Germany).
