The presence of imprecise measurement may seriously affect the efficiency of process control and production cost. A cost model is derived to determine the design parameters of the economic asymmetric $\bar{X}$ and S control charts including measurement errors. The effects of imprecise measurement on the performance of the economic asymmetric $\bar{X}$ and S control charts and production cost are examined for the case where the process mean and process standard deviation may change. Application of the proposed control charts is demonstrated through an example. Numerical examples illustrate the effects of imprecise measurement on the design parameters of the proposed control charts. It shows that the imprecision measurement may seriously affrct the ability of the proposed control charts to detect process disturbances quickly, change the sampling frequency, and increase the production cost compared to the control charts excluding measurement errors.

산업기술의 발달, 소비자의 행동변화, 업계경쟁 심화 등으로 인해 강력한 브랜드를 구축하는 일이 점점 더 힘들어지고 있다. 더욱이 브랜드는 고정 불변된 자산이 아니라 살아있는 생명체와 같아서 브랜드 수명주기에 따라 노화되기 마련이다. 따라서 끊임없이 소비자와의 관계를 통해서 자기 존재를 확인 시킬 수 있는 자기변화와 변혁이 필요하다. 즉, 시간의 흐름과 함께 또는 시장상황의 변화로 인해 진부해진 브랜드를 다시금 소비자의 인식선상으로 되돌리기 위하여 재활성화 작업이 필요하다. 본 연구에서는 단기적 과제로써 디자인 리뉴얼에 대한 효과를 측정하는 것에서 벗어나, 브랜드 수명주기에 따른 장기적 의미의 브랜드 관리에 초점을 맞추고 성공적인 브랜드 재활성화의 사례 분석과 연구 분석 대상 선정을 통한 소비자 의식도 분석결과를 종합하여 효과적인 재활성화의 시기와 방안에 관하여 규명하고자 하였다. 본 연구결과를 통하여 예측 가능한 환경의 변화에 미리 대응하기 위하여 단행하는 시기적절한 브랜드 재활성화는 브랜드 에쿼티의 하락을 미연에 방지하고 브랜드의 수명을 연장할 수 있는 중요한 방법으로 파악되었다. 또한 브랜드 재활성화는 단기적 매출 상승을 위한 전술의 개념보다는 장기적인 브랜드 관리전략으로써 BLC곡선이 하락하는 시점에서 지속적으로 실행되어야하며, 단기간에 졸속으로 이루어져 겉포장만 바꾸는 식의 외형적 측면의 디자인 리뉴얼에만 연연해서는 안 된다는 것을 확인할 수 있었다.

As a part of license renewal for the continued operation of Wolsong unit 1, the periodic safety review report was submitted near the end of design lifetime, 2012, and now is under reviewing. Major components of primary system such as pressure tubes, feeder pipes and so on are being replaced and many components of secondary system are also being repaired. So the license renewal of Wolsong unit 1 is expected to be acquired without significant issues. But on the other hand, steam generators of Wolsong unit 1 had the good performance and therefore the replacement and repair for the steam generator are not needed. Recently it is reported that some cracks were detected in a few of european steam generator with Alloy 800 tubes and the cause of cracks was the outer diameter stress corrosion cracking(ODSCC) due to the concentration of chemical impurities on the outer surface of tube. Accordingly the overall review on this issue was performed. The long-term operation is likely to results to form the concentration mechanism for the tube corrosion as the sludge build-up in the secondary side of steam generator and the crack in the crevice between tube and tube-sheet and expansion transitions is apt to be occurred. In this paper, the history of steam generator inspection and operation of Wolsong unit 1 are reviewed and the reliability of steam generator tube is evaluated and the steam generator aging management program for Wolsong unit 1 is introduced.

We evaluated the effect of CO₂ offsetting by estimating changes in carbon uptake under various forest management scenarios and proposed forest management strategies to achieve carbon neutrality. Paju and Goseong, which have relatively large forest areas but different industrial characteristics, were selected for the study sites. The current state of forest distribution was analyzed using forest type maps and aerial photographs, and the amount of carbon uptake was calculated using the equation presented by the IPCC Guidelines for National Greenhouse Gas Inventories and the national emission/absorption coefficients from the Korea National Greenhouse Gas Inventory Report. As of 2015, the forest carbon absorption in Paju and Goseong was 49,931 t/yr and 94,225 t/yr, respectively, and the annual carbon absorption per unit area was 2.28 t/ha/yr and 2.16 t/ha/yr. Under the forest management scenarios, the annual maximum carbon absorption per unit area is estimated to increase to 5.68 t/ha/yr in Paju and 4.22 t/ha/yr in Goseong, and this absorption would increase further if urban forests were additionally created. Even if the current forests of Paju and Goseong are maintained as they are, emissions from electricity use can be sufficiently offset. However, by applying appropriate forest management strategies, emissions from sectors other than electricity use could be offset. This study can be applied to the establishment of carbon absorption strategies in the forest sector to achieve carbon neutrality.

The purpose of this study is to establish the idea of sustainable slow design by analyzing literatures and preceding cases, based on the external elements of a design including forms, the methods of expression, materials and colors. This study reviewed the previous literature of books and pictures related to the research for case studies and content analysis. fashion books, magazines, and web-sites published from 2000 to 2005 were analyzed for this research. The sustainable slow design trends in fashion can be summarized as follow. The first is a timeless style which has sustain ability in design independently of the versatile fads and relies on functionality, serving the purpose of design. One of the examples is both clothes designed by Burberry and suits by Chanel. The second is a hand-touch style which the more time for outputs can be positively tolerated, in favor on eco-friendly design through the techniques of manual arts. The third is a renewable design which the combined values of design with reuse and renewal result in recreation of past ecology as shown in the technique of designs by mix & match. The forth is a transformable design which features the multi-purpose and multi-forms, eventually extending the lift cycle of products. As a result of analysis of the four designs above, it can be inferred that the representation of past styles, the mixture of old design with new design, the appropriate combination of conventional fabrics with advanced ones, the ecological trends of sports look was emerging.
