  • Quality system management adapted by small and medium enterprises in Kangwon province to enhance the competitiveness was studied. Variance analysis on several questionnaire answers was performed. Motives for acquiring the accreditation, such as product export, adjustment to international trend, enhancement of brand/product recognition, CEO's mind change, and management innovation, have been changed significantly among business types. Mind changes after the accreditations were setting company's first priority on quality, enhanced recognition on compliance of in-house standards and regulations, employee's performance with the recognition of quality. Amongst service problems to maintain the ace reditations were difficulties in maintaining the recognition of the company's finality management, labor increase to maintain the ISO 9000 enforcement team, and financial burden to keep the accreditation. Quality recognition after the accreditations was significantly improved in setting company's first priority on quality, enhanced recognition on compliance of in-house standards and regulations, employee's performance with the recognition of quality.

  • Fuel cell systems are a completely different form of electricity source that has been used so far and is an aggregation of multiple technologies with multidisciplinary features that can be operated safely only when gas and electrical safety are being considered. Since fuel cells generate through electrochemical reactions there are difficulties in ensuring electricity safety, power quality assessment, effective control and reliability standards for system faults using conventional inspection techniques and even though they are necessary as a primary means for reduction of CO2 owing to the Climate Convention, electrical safety assessment and measures are required for the prevention of faults in residential facilities. Although small-scaled distributed power supplies can be utilized as important means of peak control and energy management measures, research is required for observing the effects on the system and the development of inspection technology to ensure stable operation, and the electrical safety of residential fuel cell systems need to be assessed and the problems derived for establishing electrical safety standards. From the year 2002, Japan has established laws on technical safety standards and development and rules on the product specifications and standards for the industrialization of hydrogen fuel cells. Also, a lot of effort have been made for the commercialization of fuel cells by building one-stop certification services. Internationally, the IEC TC 105 has established international standards based on fuel cells. In order to protect the national interest, the country should be able to respond accordingly meet global standards. In fact, in Korea, to comply with the international trend, Korea Energy Management Corporation is establishing a certified agenda for fuel cells and Korean Agency for Technology and Standards is enacting technical standards for fuel cells. The current terms of fuel cells are that research has been focused more on the quality and performance of manufactured products rather than stable power operation and maintenance over time. In this paper, by considering the household fuel cell as a power device, the safety standards of the fuel cell system for a reliable operation with the existing power system is being proposed.

  • This study looked at how to establish effluent limitation standards for formaldehyde, a toxic chemical widely used in industries. To this end, we reviewed Water Quality Based Effluent Limitation (WQBEL), Technology Based Effluent Limitation (TBEL), and water quality criteria for protection of human health and aquatic organism. Based on the results, we estimated formaldehyde effluent limitation standards appropriate to control water quality of industrial wastewater in Korea. However, this study has limits due to the lack of some data necessary in estimating formaldehyde effluent limitation. For example, although water quality criteria based on non-carcinogenic properties of formaldehyde were calculated, those based on carcinogenic properties were not be able to estimate because of the absence of applicable cancer potency factor q1. Without applicable factor, we calculated water quality standards for formaldehyde based on water quality criteria of advanced countries including the United States, while with no water quality standard we referred to applicable drinking water quality standards of other countries. For eco-toxicity based on water quality criteria, proper figures could not be calculated since there have been few reliable data.

  • As BIM is now being accepted and broadly expanded in the building industry, the demand for developing, managing, submitting, and checking the BIM models has increased. To meet this demand, it is necessary to develop and spread BIM guidelines, standards, and manuals. Meanwhile, as the number of public construction projects increases, the importance of quantifying the BIM quality checking and evaluation also grows. This study aims to enhance our understanding of the definition and characteristics of BIM quality management, and review the current situation of BIM standards worldwide. In particular, by focusing on BIM quality control and its relevant subjects, the minimum standards for BIM quality management are suggested.

  • Objectives: This study aimed to present a government-led accreditation system for upgrading the quality control of herbal medicine by introducing the process and evaluation standard of external herbal dispensaries (EHDs) of traditional Korean medicine (TKM) clinics in South Korea 2018 to refer to other countries where herbal medicine were used similarly in Korea. Development Process: We organized an EHD accreditation committee for the establishment of an accreditation system. The committee consisted of 9 experts: an official of the Ministry of Health and Welfare (MoHW), a professor expert of TKM, a good manufacturing practice expert, a hazard analysis and critical control point expert, and an accreditation system expert. After 3 meetings, a draft of the evaluation standard and evaluation system was established in 2017. Based on the draft, a pilot test was conducted to determine the applicability of the evaluation standards in 2017. Two additional meeting was held to confirm the accreditation standards and was finalized in 2018. Results: The evaluation standard for EHDs was developed. In the case of herbal medicine EHDs, the evaluation standard consisted of 9 evaluation categories, 25 evaluation parts, and 81 evaluation items were developed. The results of the evaluation of the pilot tests are as follows, and the results show that there is a deviation between the EHDs. Conclusion: As a world's first, Korea MoHW successfully launched the accreditation system for upgrading the quality control system of herbal medicine not approved by Korea's Ministry of Food and Drug Safety in 2018. Our report hope to provide a good reference to other countries where having similar herbal medicine system in South Korea hoping to make better quality control of herbal medicines.
