The purposes of the research in related to FSC in JuJe experimental forests (JJEFs) is to make pre and post socio-economic comparisons and play an important role of FSC, and recognition change to FSC timbers and to make an analysis to consumers' needs. As the results of onsite survey in 2005, respondents show a high awareness of SFM and FSC in comparisons of 2004, and the JJEFs play a critical role to make SFM and FSC advertisement worldwide, such as consumers' satisfaction to SFM and FSC is high. Hence provision of JJEF information such as job creation and socio-economic impacts to stockholders could make their satisfaction improving. Most of respondents to the FSC of JJEF represent a positive rate while low awareness to FSC timber is represented. Therefore, necessary information about JJEF FSC with forest management, process and consumption pattern of FSC is required into citizens. The final results prove that FSC effects such as 1.3 billion won direct additional benefits in terms of socio-economic aspects including environmental benefits and job creation and economic effects are enough to offset 1.3 billion won additional costs.

In connection with biodiversity that has recently become the topic, competition to secure biological genetic resources is being heightened all over the world. Korea also has a variety of efforts to secure and preserve plant genetic resources, and has recognized the importance of the function and role of arboretums. Arboretums in Korea, however, have the problems in terms of quality due to the rapid increase. One of the problems is shortages in experts who are essential for the proper functioning of arboretums. To solve the problem, the State introduced Gardener Training Program certification system and started to train gardeners. However, gardeners who have actually employed at arboretums are less than 20% and thus the problem of shortages in experts still exists. In this context, this study examined 44 registered arboretums in Korea to find out the current situation of experts; analyzed arboretum experts and the program certification system in view of relevant laws; and investigated the current situation of training programs being operated in three Gardener Training Program certification organizations. Finally, this study conducted a survey of 68 gardeners who completed the training program at Chollipo Arboretum and tried to suggest a plan for securing experts from the gardener training programs. The plan for utilizing the trained gardeners as experts in arboretums is as follows: First, legal standards for the employment of experts in arboretums should be strengthened. Second, it is necessary to evaluate training programs, in order to raise the reliability of arboretum experts' expertise. Third, official validity that can be honored in all arboretums should be granted to a certificate of program completion. Finally, networks of gardeners who completed the programs should be formed through follow-up management of them.

Korea Government have carried out various policies to save the Earth environment from global warming and environmental pollution. It has also executed the Green Building Certification Criteria(GBCC) in 2002. The GBCC of office building was executed in 2003 and was revised twice in 2010 and 2011. Concerns about green building construction were quite increasing to keep the building performances sustainable. The aims of this paper is to check the reliability of weighting factors and scoring difficulties in all assessment categories of GBCC and to suggest the amendment direction of the future assessment criteria for green building. For the study, the old and new version of GBCC were examined to present the revision direction of GBCC and the 10 cases certificated by the old and new version, respectively 5 were analysed to compare with the difficulties in obtaining the certification. According to the results of the study, the GBCC requires additional amendments about the assessment categories of the energy consumption monitoring and the building commissioning as required subjects in order to secure the building performances. In addition, the operation mamagement of the building need to be assessed more intensively.

The building section is providing immediate causes for global climate change problems since it takes about 50% of carbon emission, 20~50% of waste discharge, 33% of energy consumption, 40% of resource use, and 17% of water consumption. So, many countries over the world have developed and implemented green building certification systems to assess sustainable performances of buildings since the early 1990s. In korea, the green building certification system to induce the diffusion of sustainable buildings was first introduced in 2002 and developed as an improved version of the G-SEED(Green Standard for Energy and Environmental Design) system in 2013 after major revisions of related legislations. This research conducts a survey targeting residents on an apartment building that was certified as green building and examines the importance of assessment criteria on apartment buildings to certify green buildings using the Analytic Hierarchy Process(AHP) method. And it proposes a new direction on certification assessment standards from the resident's prospective. As a result, assessment criteria such as indoor environment, ecological environment, energy & environment pollution, and maintenance management among 7 main ones turned out important on assessing the G-SEED system for apartment buildings, while criteria such as material & resource, water circulation management, and land use & transportation did relatively unimportant.

In the design of composite aircraft structures, it is very important to set material allowables and design values, which take into account certification. And when determining the material allowable and design value of composite structures, the static strength, damage tolerance requirements, and environmental effects should be considered. The building block approach has been applied to the civil and military aviation industry for a long time and provides the principal certification methodology. This current certification methodology is based on extensive testing including coupon, element, sub-component, and full scale test. In this paper, some examples of composite allowable tests have been presented and the fundamental background and application methods of the building block approach have been presented.
