This research introduces necessity to derive new certification criteria for the hospital considering healing environmental factors in G-SEED. The method of research is reference study to discuss concept of healing environment factors and case study to find ways for problem and improvement by comparison of G-SEED with foreign certification system. And the research conclusion is such as follows. First, it is necessary to develop certification criteria of the hospital for G-SEED which is lack of healing environmental assessment factors unlike foreign certification system. Second, The hospitals are certified by criteria of The Other Buildings in G-SEED which dose not take into account the characteristics of the hospital. Especially hospital waste and use of enormous water are the important factors required, which is already evaluated in foreign certification criteria.

In this report US and Korea civil and military simulator certification system is researched, and a plan for improvement is proposed. Korean simulator certification system should adopt FAA's system and improve upon it. Certification criteria should have a basis on FAA certification criteria and add military operation characteristics selectively. Flight test data, used as comparison criteria in certification, should be acquired in package during aircraft development or overseas acquisition. The establishment of certification system is expected to improve external credibility and improve competitiveness in overseas market.

The present duration of 5 years in the Korea Green Building Certification(G-SEED) should be re-set taking into account with the needs for renewal of re-certification criteria. This study methods is to analyze the differences between the characteristics of the certification system of green building of domestic and foreign and to seek the improvement to derive the problem of detailed evaluation items of the examination. The purpose of this study is to identify some problems of re-certification criteria in the G-SEED System and to propose the renewal of certification system. Analysis of the rating criteria with a few re-certified examples of office buildings have been made. Some measures to improve the re-certification have been suggested as follows; (1) it is strongly suggested to establish re-certification rating systems that is not yet made, (2) the new criteria of re-certification bring into focus on whether buildings maintain the environmental performances of the initial status certified, and (3) thus the effective duration of re-certification needs to re-set flexibly in a way to confirm to the initial environmental performances and maintenance conditions certified.

항공기 시스템에서 소프트웨어의 사용이 증가 추세에 있어 안전 및 보안 위협에 대한 노출이 점차 증대되고 있다. 소프트웨어 안전에 관한 인증기준은 DO-178C가 발표되었으나, 소프트웨어 보안을 위한 인증기준은 포함되어 있지 않다. 한편 최근 항공기 및 시스템 감항 보안 인증기준으로 DO-326A, DO-356 및 DO-355가 별도로 발표되었다. 그러나 안전과 보안의 인증을 위해 각각의 기준과 절차를 준수함으로써 별도의 비용과 노력이 요구되는 실정이다. 따라서 본 논문에서는 안전과 보안을 위한 각각의 인증기준을 하나로 통합하여 비용, 노력 및 시간 등을 감소시킬 수 있는 효율적인 통합인증 방안을 제시하고자 한다.

Many countries have carried out various policies about sustainable building to protect the earth against the global warming and environmental pollution. Korea government has also executed the Green Building Certification System. In order to keep the performances of certificated buildings sustainable, the effective building maintenance is quite necessary. Meanwhile, the foreign green building certification systems have considered the building maintenance as one of the most important items to keep the building performance effective. However, Green Building Certification Criteria(GBCC) of Korea has not had the sufficient criteria for the maintenance of green building. Therefore, The purpose of this study is to find direction for the improvement of management categories of Korea Green Building Certification Criteria. For this aim, GBCC was compared with the foreign certification systems such as LEED, BREEAM and CASBEE.

Purpose: The green building certification system in Korea was introduced in 2002 and developed as an improvement version of the G-SEED(Green Standard for Energy and Environmental Design) system in 2013. This study conducts surveys targeting architectural designers and users on significance of certification assessment criteria for apartment buildings on the G-SEED system and examines the differential views between the two groups on assessment criteria. Method: First, The AHP(Analytic Hierarchy Process) method was used to find importance of assessment criteria and then the importances were compared with weighted points on the certification standard. Second, the t-test was used to investigate differential views between designer and user groups on certification assessment criteria based on drawn importances. Result: (1) While designer group considered land use and transportation, energy and environmental pollution, and water circulation management as more important, user group did material and resource, maintenance management, ecological environment, and indoor environment as more important. (2) Based on t-test results, sustainable energy, water circulation system, site management, habitat, acoustical environment, and light environment were found to be different on importance between the two groups.

The paper provides the approach to apply formal methods to the development and certification criteria of defense safety/security-critical software. RTCA/DO-178B is recognized as a do facto international standard for airworthiness certification but lack of concrete activities and vagueness of verification/certification criteria have been criticized. In the case of MoD Def Stan 00-55, the guidelines based on formal methods are concrete enough and structured for the defense safety-related software. Also Common Criteria Evaluation Assurance Level includes the strict requirements of formal methods for the certification of high-level security software. By analyzing the problems of DO-178B and comparing it with MoD Def Stan 00-55 and Common Criteria, we identity the important issues In safety and security space. And considering the identified issues, we carry out merging of DO-178B and CC EAL7 on the basis of formal methods. Also the actual case studies for formal methods applications are shown with respect to the verification and reuse of software components.

Over the world, social demands and concerns of energy and resource depletions and environmental conservation have resulted in many researches and applications on sustainable development and construction. In order to support these demands and concerns, international green building certification systems such as LEED(Leadership in Energy and Environmental Design) and BREEAM(Building Research Establishment Environmental Assessment Method) were developed. In Korea, the green building certification system was introduced in 2000 and widely applied to all types of new buildings in order to induce the diffusion of sustainable buildings on May, 2010. This paper investigates the importance of assessment criteria on multi-unit apartment projects among certification rating systems using the AHP(Analytic Hierarchy Process) method and suggests a new direction on certification assessment standards. For applying the AHP method, the survey of staffs in green building certification consulting companies and architectural design companies was conducted via e-mail. As a result, criteria like energy, indoor environment, land use, pollution control, and ecological environment among 9 main ones turned out important on assessing green building certification at multi-unit apartment projects, while criteria like water resource, transportation, maintenance management, and material and resource did relatively unimportant.

Green Building Certification System currently going into effect is a static evaluation model. Therefore, as far as the sustainable development of certification system is concerned, further long-term evaluation is required. The main purpose of this study is to offer a model in a way of developing and verifying a dynamic model in Green Building Certification. A dynamic model development has been given System Dynamics based on the causal structure. Thus, this study focused on searching the causal structure of certification criteria and verifying the reality of the model through simulation processing after developing a model. In conclusion, the development of dynamic evaluation method can be attributed to systematic evaluation for the criteria of Certification System.
