There are a number of factors affecting the continued airworthiness of composite structure. Unlike metal structure, damages made in manufacturing processes or maintenance repair procedures need to be considered. The different levels of degradation and damage, which may occur, must be considered for structural substantiation of static strength, stiffness, flutter, and damage tolerance. This can start with an evaluation of environmental effects for the particular composite material. Matrix-dominated composite properties, such as compressive strength, are most sensitive to moisture absorption and temperatures. Static strength substantiation includes the smaller damages that will not be detected in production or maintenance inspection while damage tolerance addresses larger damages that need to be repaired once discovered. In this paper, we intend to list the airworthiness regulations and advisory circular that are deemed closely related to the certification of composite airplanes.

Objectives: This study examined the nutrition teachers' and parents' recognition of environmentally-friendly agricultural products (EAPs) used in school foodservice. Methods: A questionnaire survey was given to 128 school foodservice nutrition teachers in Seongnam and 189 parents from Oct. 16 to Oct. 31, 2018 at Seongnam in Gyeonggi province. The survey included information on the recognition, satisfaction, and improvement of EAPs, and the results of the two groups were compared. Results: A comparison of the recognition of EAPs showed that nutrition teachers knew more about the EAPs and local government support in school foodservice than the parents. On the other hand, the parents were more aware than the nutrition teachers in that children have a higher affinity for EAPs than for general agricultural products in the school foodservice. A comparison of the level of satisfaction with the EAPs by nutrition teachers and parents revealed the nutrition teachers to be significantly more satisfied than parents in terms of the color, taste and nutrition of EAPs. Among the items that should be provided with EAPs, more than 50% of each group of nutrition teachers and parents answered that vegetables must be provided first. Some 70.9% of nutrition teachers and 84.5% of parents were aware of the certification standards of EAPs. The nutrition teachers had showed a slightly higher score than the parents in the certification system (3.51 vs. 3.25). In terms of improving the EAPs, 36.2% of nutrition teachers answered a reasonable price preferentially, whereas 56.4% of parents answered maintaining quality. In the expected effects of using EAPs, 57.9% of nutrition teachers answered an improvement of parents' satisfaction on the school foodservice. On the other hand, 38.0% of parents answered an improvement of children' satisfaction on school foodservice. Conclusions: Nutrition teachers and parents need to be educated on the certification systems that would enhance the trust in EAPs.

This research topic evaluates the effectiveness and importance of environmental protection in the 21st century in light of the increasing demand on the earth's natural resources and the pressures on economic and industrial development to provide dynamic power. As the world and our fellow citizens become more conscious of environmental protection, companies are under greater pressure whilst pursuing economic growth. Therefore, domestic manufacturers have been devoting efforts to promote environmental management. This research conducts survey using questionnaires on the operational performance of the manufacturers who have ISO 14000 series accreditation and certification. The survey considers five dimensions/functions within a manufacturer, financial management, human resources management, production management, and marketing management. A total of 35 indices are used for analysis of the effects that the location, history, industry, number of employees, amount of capital, and revenue may have on the performance. This research targets the manufacturers approved of ISO 14000 series certification by Environment Administration Association. The statistical methods deployed are descriptive statistics, T-test, and single factor analysis of variance used for analysis. The conclusions reveal that a certain level of performance has been achieved in every dimension. After T-test, all the indices have reached a significant level. The indications are that ISO 14001 benefits all manufacturers the level of benefits however varies from company to company.

In this study, based on the System Dynamics (SD) methodology, the interrelationship between the factors inherent in the operation of the New Technology Certification System (NTCS) in Korea was identified by a causal map containing a feedback loop mechanism in connection with 'new technology development investment', 'commercialization of new technology', and 'sales by new technology'. This conceptualized causal map was applied to the simulation of the operations of the New Excellent Technology and Environmental Technology Verification System (NET&ETV) run by the Ministry of Environment among various NTCSs in Korea. A SD computer simulation model was developed to analyze and predict the operational performance of the NET&ETV in terms of key performance indices such as 'sales by new technology'. Using this model, we predicted the future operational status the NET&ETV and found a policy leverage that greatly influences the operation of the NET&ETV. Also the sensitivity of the key indicators to changes in the external variables in the model was analyzed to find policy leverage.

ISO9000 set of standards has been widely applied in Iranian Automotive manufacturing industry. Regarding the effects of TQM and ISO9000 set of standards various studies have been conducted and different quantitative conclusions have been made. Due to lack of quantitative information, in many of the cases, using qualitative information becomes the best option. The qualitative nature of data in such cases, requires qualitative analysis methods that might lead to some challenging computational issues. This paper examines the impact of ISO9000: 2000 certification and its perceived benefits for an automotive manufacturing company. Using an empirical approach, the paper seeks to ascertain if certification has indeed improved the performance of the company. Our null hypothesis rotates around the effect of ISO9000: 2000 on the 4W's of an enterprise. To carry out the research, first we developed a couple of questionnaires including all criteria of ISO9000 and 4W's. Second, the questionnaires were discussed with two researchers knowledgeable in the field, and then submitted to the quality practitioners and executives of Iran Khodro Enterprise-a leading company in Iranian automotive manufacturing industry. Finally the null hypothesis was tested and the technology improvement dimensions were ranked through nonparametric tests. The results illustrated a reasonable cause and effect relationship, suggesting that ISO9000: 2000 has positive effect on the 4W's of company result. In this work we investigate the effect as technology improvement viz., the improvement of techno-ware, human-ware, info-ware, and organ-ware.

In recent years, IT organizations are in the process of introducing IT Governance as the concept and measure of transparency, accountability and effectiveness of IT activities and control for managing governance processes. In this paper, the influential factors for IT organizations to adopt COBIT(The Control Objectives for Information and related Technology) which is a typical framework for effective IT Governance execution were classified and analyzed empirically into internal and external factors. Internal factors were designed based on influential factors in the theory of innovation diffusion, and external factors were designed based on influential factors from outside certification which were absent in COBIT and expertise support from the outside. The result of this study showed that understandability, transition and effectiveness which were internal factors had no effect on COBIT introduction, and only expertise support among certification and expertise support which were external factors had significant effects. This result shows that there are lack of COBIT supports and introduction in internal IT organizations. It is expected that the result of this study will allow strategic approach of COBIT adoption in future by verifying influential factors of COBIT introduction within IT organizations.
