It is evident that in the wind energy business as an economic activity there is a close relationship between the wind speed and the revenues. The wind turbine test facility for wind turbine accreditation is intended to be used by the industry for testing of both main components and systems. This paper suggest the wind test site for certification of prototype wind turbine with international regulations. The test site has an environmental permit for wind turbines with a maximum hub height of 120m and a rotor diameter up to 120m, and can accommodate prototypes with installed electrical powers up to 5MW each. A wind turbine manufacturer can lease the location for a period of type certification. And also researchers are the development of new methods for measuring the influence, performance and durability of the components, a mathematical and numerical modelling of component responses by using the site.

This study investigates the effect of organic certification of apples on consumer preference in China as a way to support the expanded export of Korean apples to China. A choice experiment was designed to analyze the apple consumption in China. A total of 298 Chinese consumers answered the survey, and multinomial logit models were used to analyze the results. Organic certification was identified as an important determinant of consumer preference for apples in China, affecting both the evaluation and choice of country of origin. The results also indicated that Korean organic certification significantly increased the probability of Chinese consumers choosing Korean apples. Thus, organic certification by the Korean government should be strengthened to promote apple exports to China, plus the results of this study may provide useful information to promote agricultural product exports and improve the organic certification system.

Strengthening vehicle emission regulation is one of important policies to improve air quality in urban area. Due to the limitation of specified driving cycles for certification test to reflect real driving conditions, additional off-cycle emission regulations have been adopted in US and being developed in Europe. The driving cycles of US or Europe have been used in emission certification for Korean light-duty vehicles, but it has not been known how well the driving cycles reflect various real driving patterns in Korea. In that point of view, it is required to estimate vehicle emission based on real road driving conditions to raise the effectiveness of vehicle emission regulation in Korea. In this study, real driving emission measurements have been conducted for three Korean light-duty vehicles with PEMS. The driving routes consisted of urban, rural and motorway in Seoul and Incheon. The data have been analyzed with various averaging methods including moving averaging windows method and compared to emission limits set with emission certification modes applied to tested vehicles. The results have shown that the real driving pollutant emissions of a gasoline and a LPG vehicles have been ranged quite lower than those of emission limits on CVS-75 driving cycle. But real driving NOx of a light duty diesel vehicle has been considerably higher than emission limit of NEDC driving cycle. The higher than expected NOx emission of a diesel vehicle might be caused by different strategy to control EGR in real driving condition from NEDC driving.

Purpose: This study aimed to suggest strategies for advancing local-government-based accreditation systems and surveyor training in long-term care facilities in Korea. Methods: A comprehensive review of the literature including research papers and official reports issued by governments from the United States, Australia, and Japan was conducted to explore domestic and international policies related to long-term care facility certification and accreditation systems. Results: The USA has two types of care quality assurance systems including mandatory certification (5-star rating system) by the Centers for Medicare and Medicaid Services and voluntary accreditation by the Joint Commission on Accreditation of Healthcare Organizations. Australia operates a government-based mandatory accreditation system for all long-term care facilities through the Australian Aged Care Quality Agency. Japan, particularly the Tokyo district, operates a third-party evaluation system that involves the voluntary participation of long-term care facilities. Conclusion: This study provides several strategies to enhance accreditation processes and surveyors'expertise. For instance, motivating facilities to voluntarily participate in accreditation is necessary by 1) providing sufficient and continuous consultations and feedback about how to improve care quality, 2) differentiating accreditation domains and indicators from the national health insurance certification system, and 3) actively utilizing accreditation results and providing incentives.

This study was performed to figure out the recognition on forest certification by consumption propensity and socio-economic characteristics of wood cabinet consumers. The mean score of recognition on SFM and FSC showed comparatively low, 2.25 and 2.20(5-point likert scale), from the analysis result on 88 valid questionnaires of 90. The respondents rate of eco and non eco-friendly group formed 80.7% and 18.2%, there is a significant gap between two groups on total questionnaires. The percentage of respondents recognizing on SFM and FSC was about 31% (eco-friendly), 5.6%(non eco-friendly, SFM) and 2.8%(non eco-friendly, FSC) within each group. It showed that the socio-economic characteristics on eco-friendly respondents were higher than the others about more 1.3 times in the married rate, average age and monthly householding income.

As the importance of national technical qualifications for hairdressers to verify qualifications and skills as a professional is increasing, it is time to improve achievement motivation and job attitudes through research on job attitudes perceived by hair designers toward hair practical tasks. As a result of studying the effect on the job attitude of a hairstylist working in a hair salon, it was found that blow-drying induced the hairstylist's job efficacy among the practical tasks for the hairdresser's hair national technology certification, and scalp scaling and shampoo were the job of the hairstylist. was found to induce satisfaction. Based on the research results, it is possible to present a variety of practical certification tasks with practicality that can be usefully applied to customers in various techniques in the beauty industry, rather than unrealistic practical techniques limited only to wigs. We want to induce improvement. In addition, I believe that this study will provide basic data for the development of various practical tasks to improve the achievement motivation of hair designers.

PGP is an encryption software designed to provide information protection, security and authentication services for online communication systems. The characteristic of behavior done on the Internet is that you don't know the other person. It is very important to protect information from someone you cannot trust. So identification of the other person is an important task. PGP uses an digital signature algorithm to verify the identity of the other party. However, it is not accurate to check the other party's credibility. PGP increases trust as other users sign more on public keys of user. In other words, credibility is not perfect. In this paper, PGP certification system that key management in Ethereum blockchain, one of the blockchain platforms, is proposed. Key management in blockchain ensures data integrity, transparency and reliability.

The last few nears have seen significantly increased interest in organic food. Organic food is still a small but growing part of the food industry with an identity defined and protected by law. Its existence provides an element of consumer choice. To obtain consumer confidence and, product credibility and transparency in the organic market, organic legislation and certification is needed, To facilitate export of organic products, harmonization of the organic legislation is favoured. The IFOAM accreditation programme has already achieved very much in this respect. Several national regulation, such as the NOP(USA) and EC2092/91(European Union) have already complied with the IFOAM basic standards. But in many countries there is still a lack of national legislation on organic agriculture. Because of the fast globalisation, organic agriculture is facing major challenges for international trade, so it is very important to consider the future development and certification of organic produce in all countries.
