Recently due to the crisis of environment and resources, construction industry that effect a lot on nature than any other industries is essentially required to consider environmental element through the life cycle. Lots of advanced countries and Korea have already been running green building certification systems. However, GBCC(Green Building Certification Criteria) in Korea is lack of assessment criteria that apply environmental characteristics of tall building in compared with that in advanced countries. To improve the problem, we compared GBCC with LEED(Leadership in Energy and Environmental Design) through the case study. This study provides preliminary data for reflecting environmental characteristics of tall building in GBCC.

The goal of this study is to compare the evaluation results of indoor daylight environment for each certification and propose improvement points. As the importance of indoor daylight environment has increased, foreign countries have been aware of this and have changed the light environmental certification items. On the other hand, Korea environmental certification systems have not been able to follow the current situation. In order to improve this, this study intended to find evaluation criteria for each category by comparing and analyzing indoor daylight environment certification items in Korea's G-SEED, LEED in the United States, BREEAM in the UK, and CASBEE in Japan. After that, this study simulated 3D models of three spaces about classroom, reading room and club room of Yanghyun elementary School which is scheduled to be constructed for the evaluation of indoor daylight environment, and the results were analyzed to suggest for improvement.

This study was conducted to provide sustainable measures for conservation and management to protect valuable natural/ecological resources, offer differentiated quality assurance services for eco-tourism products, and explore measures for eco-tourism certification/designation systems. To achieve its goals, the study discussed domestic and overseas trends and literatures that concern eco-tourism certification/designation system and investigated case studies that were presently operational. A group of experts and a group of non-experts were surveyed separatedly to investigate the awareness of the national eco-tourism certification/designation system. The results from the investigation indicate that Europe, since the late 1990s to early 2000, has actively introduced a system that establishes and operates a dedicated institution, and European members have created a cooperation framework to formulate international partnerships and develop standardized assessment benchmarks to adhere to the goals of the system, the period for certification was designated from one year to five years, and renewals were granted based on periodic monitoring and reassessment. In Korea, from early 2000, the Ministry of Culture, Sorts and Tourism and other organizations have certified product quality and assessed travel products and national park tour programs. The certification period was established to be set between one and three years, and the vast majority were not reassessed. Upon investigating the results for awareness of national eco-tourism certification/designation system, a high number of respondents agreed with the need to establish a eco-tourism certification/designation system (90% of respondents), and the respondents cited eco-tourism quality assurance, conservation of value, means to maintain established institutions, and environmental education and information as reasons for needing a certification/designation system. In Korea, a certification/designation system for the eco-tourism industry is presently in operation, but the system regulates target institutions based on their characteristics. Therefore, this study proposes its suggestions via various categories, including designated institutions, designated purpose, designated subjects, designated organization, laws, regulations, and incentives.

The purpose of this study is to analyze the effect of eco-friendly building certification grade on the price and cost of office in Seoul office building. For this purpose, multiple regression analysis is used to examine the prices of buildings. In order to identify the effect of environmental cost reduction of buildings with high eco-friendly certification, we also performed LCC (Life Cycle Cost) + LCA (Life Cycle Assessment) analysis. Results of our analysis show that office buildings with a higher level of eco-friendly certification are priced significantly higher. Through LCC analysis, it was also found that buildings with high levels of eco-friendly certification cost less than those with lower-level certification. Furthermore, it was confirmed that office buildings with higher-level environmental certification have total lower environmental load costs (TCA = LCC+LCA) than buildings without certification. According to the TCA analysis, buildings with a high level eco-certification generated lower social costs than buildings with lower-level or no certification.

As environmental concerns grow, people are becoming more aware of energy efficiency, carbon reduction, and sustainable development. Leadership in Energy and Environmental Design (LEED) certification is currently the most widely recognized building environment assessment method connected to energy and the environment worldwide. This study explores trends for six factors (energy and atmosphere, materials and resources, indoor environmental quality, sustainable sites, water efficiency, and innovation in design) to assess four levels of LEED certification (Platinum, gold, silver, and certified) using 11,209 LEED projects in the United States. The study analyzes trends using scores of percentages of maximum points by certification level, ownership type, space type, and climate zones. With the interest in the Environmental, Social, and Governance (ESG) principle on the rise, this study contributes to a better understanding of the trends and future of LEED certification in the built environment sector.

Environmental issues have become gradually important around the globe, which has increased society needs for the environment-friendly construction. In an effort to realize the environmental protection and energy efficiency, the British BREEAM has been developed, which is followed by the USA LEED, Japanese CASBEE and other national certification systems based on their own conditions. In this end, the Republic of Korea has implemented its own certification system named GBCS(Green Building Certification System) in 2002, and now actively promoted the G-SEED(Green Standard for Energy and Environmental Design) after GBCS modifications and amendments. The purpose of this study is to identify possible problems to be encountered in the process of the G-SEED for office facilities and to provide relevant solutions. In this end, three office facilities have been selected, which had obtained the G-SEED. This study has analyzed reasons of change of assessment scores between the preliminary certification and the main certification phases, has identified problems through in-depth interviews with practicing professionals(design, construction, eco-friendly consulting firm) and then has reached a conclusion for improvements. This study will be possibly used as reference materials for improvements of the green building certification system, and further detailed studies on respective parts will be required for improvements.

BLDC motors are stored in the devices such as CD-RW, COMBO, DVD-ROM and CD-ROM. It is indispensable to establish reliability assessment criteria for BLDC motors, especially in the world where IT grows rapidly. In this article, reliability certification procedure is given. The reliability certification procedure consists of two separate tests such as quality certification test and lifetime test. The former quality certification test comprises general performance test and environmental test. Items which pass the test undergo lifetime test which guarantees the extent of mean lifetime with certain confidence.

This study is purposed on applying to certifying environmental-friendly buildings about remodeling schools as an issue recently, keeping up a worldwide resource conservation movement. Application standard is directed, comparing with systems certifying green-schools in domestic and foreign policies. The following is the primary result of this study. First, on developing systems for certifying environmental-friendly buildings about remodeling schools, characteristics like ‘the phase of certifying essential lists and the diversity of certifying lists’, ‘developing departmentally into new-building, reconstruction, remodeling, existing-building in basic data’, ‘development of certifying existing-buildings as well as new-building’ in foreign systems should be developed appropriately for Korea. Next, not only reuse of the existing facilities but better assessment through diversification of classified contents in domestic system are carried out in comparing remodeling lists. Especially the primary list that is found out commonly limited lists certifying remodeling should be developed appropriately. Impossible lists getting certification should be applied to map out a concrete standard. Lastly, the range of certification should be diversified and developed sustainable like other systems for better assessment. Adding various lists suiting for Korea and departmentalizing score of phases and items in particular, for avoiding a needless collision between certification lists, absence of them. Above of all, basic direction about certifying environmental-friendly buildings about remodeling schools should be developed the only individual instrument, not for gaining it simply as a part of the environmental policy in Korea. This study has significance on vitalization of certifying environmental-friendly buildings, which performing primary environmental-friendly education facilities, based on its advance.

Objectives: Wearing medical masks has been recommended since the declaration of coronavirus disease-19 (COVID-19) as a pandemic disease. Certified medical masks are evaluated according to filtration efficiency and facial inhalation resistance. However, some people use non-certified common masks. This study aimed to evaluate various non-certified commercial masks based on the certification criteria for medical masks. Methods: Twenty mask products (three anti-droplet, three disposable dental, eight fashion, three cotton, and three children's masks) were selected. For performance evaluation, filtration efficiency and facial inhalation resistance tests were conducted. The evaluation method followed the certification method for KF-certified masks of the Ministry of Food and Drug Safety (MFDS) and the N95 respirator of the National Institute for Occupational Safety and Health (NIOSH). Results: None of the 20 masks met the KF94 certification standard set by the MFDS. Four and three masks respectively met the KF80 certification standard and the N95 standard of NIOSH. Filtration efficiency was significantly higher in three-layer masks than in single layer masks. Pleated-type masks had higher filtration efficiency than cone-type masks. There was no correlation between the structure of masks and facial inhalation resistance. Conclusion: While no masks complied with the KF94 certification standard, a few masks met the KF80 and the N95 certification standards of NIOSH. Although some people wear non-certified commercial masks, protection from aerosols is not guaranteed by such masks. Evaluation of the protection efficiency of non-certified mask against microbiological infection is needed for the prevention of infectious disease.

With the adoption of the Paris Agreement, a new climate regime is intensifying the global interest in reducing greenhouse gas emissions. In the meantime, Korea is preparing to introduce a new renewable energy carbon certification system in order to activate the use of renewable energy and to reduce carbon emissions in the entire life cycle of manufacturing and disposal of renewable energy facilities. Therefore, this study aims to identify the implications for the introduction of the carbon certification system and to establish a theoretical basis for the system design by examining the status of overseas carbon certification, international trade norms and trade disputes. As a result, carbon emissions certification is being implemented in developed countries such as EU, UK, France, USA and Japan, but only France, Germany and EU have adopted carbon certification for renewable energy sector. The analysis of the WTO TBT Agreement and GATT also confirmed the possibility of a violation of the international trade rules of the carbon certification system and derived nine international technical standards related to carbon certification. Finally, by examining the case of trade disputes related to environmental labeling, the minimum requirements to be considered at the institutional design stage were drawn to eliminate the possibility of trade disputes.
