A study on the sustainability evaluation of the requirements of the mobile industry closely related to the human factor was needed. We conducted the sustainability evaluation of the mobile industry using a quantitative evaluation method with the AHP tool and a qualitative evaluation method reflecting the technological age flow of the philosophical thoughts to improve the reliability of the evaluation results of the model verification. And this evaluation is to evaluate the consistency of the connection between the national sustainability and the mobile industry. In order to draw the conclusion of the relevance, the team member Delphi 5-point scale was used. As a result, the priority was confirmed in the national sustainable development indicator and mobile industry indicator. Quantitative and qualitative evaluation was applied to the discontinued model of mobile to derive insufficient indicators, and it was confirmed that if the indicators were improved and reflected, it would be sustainable. And in order to secure reliability and accuracy, we made a proposal to apply the systems engineering process to the development of the model evaluation field. The systems engineering technology process meets the needs and requirements of stakeholders throughout the lifecycle and it is suitable for the development model of the industry's sustainability assessment.

Human Resources Development of Korea has been practicing performance evaluation for occupational qualification licences in environmental sectors that include water, air, and wastes management, but not soil. The purpose of the study was to improve overall quality of the national qualification test in the soil sector to better train applicants based on National Competency Standards (NCS), which is designed to emphasize site-specific conditions and knowledge. This study systematically analysed the current licence test in the soil sector with respect to qualification units, performance criteria, knowledge, techniques, and attitude as described in NCS. Furthermore, test evaluation was conducted to examine the validity of the revised licence test. The test results indicated the revised test method would bring positive outcomes to the related industry. Upon the reviews and amendments by the field experts, the result of this study could serve as a framework to the development of more robust and reliable licence test.

오늘날 중소기업의 기술개발은 미래 산업에 대한 성장엔진이다. 또한 기술력 평가는 기업과 국가 경쟁력에 대한 중요한 평가 항목으로 R&D 투자를 지속적으로 확대해가고 있다. 그러나 R&D의 생산성을 제대로 측정하고 평가하는 기업은 거의 없는 것이 현실이다. 본 논문에서는 기존의 기술가치평가, 기술 평가의 연구의 한계점을 보완하는 중소기업 대상의 U-IT TE 및 PSMP 설계 Model을 제시하여 기술 환경 및 기업의 기술 관련 능력을 종합적으로 평가하는 도구로 활용하고, 기술을 정량적으로 분석 평가하고 제품 생산 완료까지의 Process를 정형화하는 Model을 제시하고자 한다.

A large number of residential buildings in regions subjected to severe earthquakes do not have enough load carrying capacity. The most of them have been constructed without receiving any structural engineering attention. It is practically almost impossible to perform detailed experimental evaluation and analytical analysis for each building to determine their seismic vulnerability, because of time and cost constraints. This fact points to a need for a simple evaluation method that focuses on selection of buildings which do not have the life safety performance level by adopting the main requirements given in the seismic codes. This paper deals with seismic assessment of existing reinforced concrete residential buildings and contains an alternative simplified procedure for seismic evaluation of buildings. Accuracy of the proposed procedure is examined by taking into account existing 250 buildings. When the results of the proposed procedure are compared with those of the detailed analyses, it can be seen that the results are quite compatible. It is seen that the accuracy of the proposed procedure is about 80% according to the detailed analysis results of existing buildings. This accuracy percentage indicates that the proposed procedure in this paper can be easily applied to existing buildings to predict their seismic performance level as a first approach before implementing the detailed and complex analyses.

시스템의 소프트웨어 아키텍처를 설계하기 위해서는 여러 아키텍처 스타일들이 복합적으로 결합하여 시스템의 전체적인 아키텍처를 구성하게 된다. 이 때 다양한 아키텍처 스타일 즉, 아키텍처 접근법들 중 어떤 것을 선택할 것인가는 완성될 시스템이 어떤 기능적, 비 기능적 품질요구사항을 만족시켜야 하는지에 따라 달라지게 된다. 본 논문에서는 아키텍처 접근법 선정을 위한 평가모델을 기반으로 아키텍처 접근법의 기술적인(technical) 부분에 대한 평가를 통해 시스템의 요구사항에 대한 만족도를 결정하여 가장 적합한 아키텍처 접근법을 선정하도록 하는 평가 방법을 정의하고, 메시지 시스템의 아키텍처 접근법을 선정 시 본 평가 방법을 적용하는 사례연구를 통해 본 평가 방법을 검증한다.

As a new technical approach, this paper introduces a method for improving an electrically propelled outboard motor in consideration of the driving system applied to an electric-propulsion boat with solar cell energy. The most efficient model for a drive shaft, propeller shaft, and bevel gear was suggested and examined with respect to the results of test operation in prototype mode. Furthermore, this research included a performance evaluation of the manufactured prototype to acquire the purposed quantity value and the development items. After manufacturing the desired prototype of an electrically propelled outboard motor, the maximum sail time, thrust force, noise, and weight were evaluated in a performance test. An additional test in relation to the maximum sail speed (knots) of the completed prototype was conducted using a sea trial evaluation to acquire the optimum quantity.

정보보호수준 검증방법은 프로세스를 중심으로 정보보호 제품, 시스템, 서비스를 개발하려는 조직의 개발능력을 평가하는 SSE-CMM(System Security Engineering-Capability Maturity Model)모델이 있다. CMM은 소프트웨어 개발업자의 개발능력을 평가하고 개선시키며 조직 전체의 성숙도 수준을 측정하는 모델이다. 그러나 이 방법은 보안엔지니어링 프로세스의 개선과 능력을 평가하는데 조직차원이 아닌 개별 프로세스의 능력수준 평가에 그치고 있다. 본 연구과제에서는 이들 기존연구를 근간으로 기술적 관점에서 정보보호수준 성숙단계를 정의하고자 한다. 연구방법은 정보보호취약점 진단, 기술보안체계 검증, 기술보안 이행실태 진단으로 구성한다. 제안하는 방법론은 업무현장에서의 범위와 수준에서 정보시스템의 현재 상태, 취약점 실태, 정보보호 기능 이행과 기능만족도 수준을 평가한다. 제안된 방법에 의한 평가결과는 정보보호 개선대책 권고모델 수립 근거로 활용하여 정보보호 개선의 활용을 목표로 하고 있다.

Numerical damage assessment of Van train station building consisting of three RC blocks due to 2011 Van Earthquakes by nonlinear dynamic analysis is presented. The structural model is created with rigid-end offsets and plastic hinges for nonlinear analysis. Rigid-end offsets are considered for connection areas and proposed for wall-supported elements. In wall-supported elements, walls take place in a limited part of the columns. Nonlinear dynamic analysis of the building with and without rigid-end offsets is performed by using real earthquake records and results are compared. The results show that rigid-end offsets have significant effects on the seismic behavior of the structures.
