  • The growing importance of product quality is becoming more and more daily apparent as we enter the age of globalization around the world. And the product safety is getting more focus as well as product quality. As a result, many domestic companies are putting a lot of emphasis on safety measures and management activities and these companies' products are mainly superior to other companies' product. When we separate the product quality procedure into 3 steps, i.e. quality secure-quality confirm-quality guarantee, of course the 1st step is the most important, but also 2nd step of product quality confirm process is important. And in mass production environment, sampling inspection is more desirable than the $100\;\%$ inspection procedure. As a part of globalization trend, KS system is also being revised and reestablished based on ISO, IEC, etc. which are based on international standard. Conventional KS sampling inspection standards were in many areas quite different from ISO sampling standards, only KS A 3102, 3104, 3151 are left and the rest become obsolete, and even the ones that are still around are planned to the gone step by step. It has been already 3 years since the new KS A ISO $2859-0\sim3$ sampling inspection process has been established which the abolition of the popular KS A 3101, KS A 3105, KS A 3109, yet the implementation rate is very slow. This study will attempt to analyze the new KS A ISO 2859-2 and KS A ISO 2859-3, and try to understand the difference as that the new standard can be easily understood and used widely among companies, by using examples. Our attempt is to help implement with the companies with active safety involvement but the final result can be spread among other companies as well in the near future.

  • KS 가구 규격 내의 치수를 적절하면서도 일관성 있게 설정하기 위해서는 인간공학적 설계원칙이 정립되어 있어야 한다. 그러나 이제까지의 KS 가구 규격은 일본 JIS 규격의 치수를 그대로 가져와 사용한 경우가 거의 대부분이었다. 이에 본 연구에서는 KS 가구 규격 35 종에 포함된 가구들에 대한 치수항목 중 인체측정치를 반영해야 할 것들을 선정하고 이에 맞는 인간공학적 설계 가이드라인과 산정 수식을 개발하였다. 이를 이용해 현행 KS 가구 규격의 치수들에 대한 검토를 하였고, 맞지 않는 것들에 대해서는 수정 안을 작성하였다.

  • Opens the construction market recently, the construction industry of Korea has faced up to the barrier of globalism, and has been enforced to follow the various global standards in many aspects. Accordingly, it is expected that the test method related to the cement and concrete will be changed to conform to the international standards in Korea. Therefore, in this study, the strength tests are executed for the cement mortars, made by KS and ISO standards respectively, and then obtains such results. 1) The flow of the cement mortar according to ISO is about 8% higher ,than that of KS. 2) The flexural strength of the cement mortar according to ISO is about 10~20% higher than that of KS, and the compressive strength is about 30% higher. 3) The compressive strength relation between the cement mortars of KS and ISO may be expressed in the first-order recurrence formula as follows: Y = 1.33X - 8 In which X is the compressive strength(kgf/$\textrm{cm}^2$) of the mortar according to KS and Y is the compressive strength(kgf/$\textrm{cm}^2$) of the mortar according to ISO.

  • Marine baceteria of fish interstines were screened for high eicosapentaenoic acid(EPA) productivity. An isolated bacteria, KS-90, identified and designated as Allteromonus putrefaciens KS-90. A. putrefaciens KS-90 was found to be a rich source of EPA production and it was observed on incuibation at 4~12.5$^{\circ}C$ and pH 7.0. The production of EPA reached 18mg/g of dry cell weight when A. putrefaciens KS-90 was grown in the medium containing 1.0% pepton, 0.5% yeast extract, 0.025% meat extract and 2.0% glucose in 1/2 concentration of an artificial seawater, pH for 48 hr at $25^{\circ}C$. This value accounted for 24.7% of the total fatty acid in the extractable lipids.

  • This study was conducted to investigate the growth characteristics of the shoot and roots and to analyse the morphological characteristics of roots of waterlogging resistant and susceptible maize inbred lines. Six maize inbred lines were treated with waterlogging for 10 days at V3, and the degree of leaf senescence was evaluated for waterlogging resistance. As a result of waterlogging resistance evaluation, KS85 was the most damaged inbred line with 3.33 senescence leaves and 5.54 degree, and KS141 was the least damaged inbred line with 1.33 senescence leaves and 3 degree. At 20 days after treatment, the effect of waterlogging stress on the shoot dry matter accumulation of KS85 and KS141 were decreased by 86.1% and 77.0%, respectively, compared to the control. Similarly, root dry matter accumulation of KS85 and KS141 were decreased by 77.6% and 65.0%. As a result of SEM photographs of the nodal roots of the two maize inbred lines, the thickness of cortex of KS141 was thicker than that of KS85, and the distortion of the cortex was observed in KS85 at 20 days after waterlogging. It was concluded that the thickness of cortex was related to maize waterlogging resistance.
