We selected 25 pairs of progressive power lenses from 5 companiesOO pairs from higher price group brands and 15 pairs from lower price group brands) among higher domestic market share products and investigated whether they met tolerances regulated by the Organization for International StandardizationOSO). The range of far area focal power was from -2.50D to -3.00D and addition power was from + 2.00D to + 2.50D. The average error from far area focal power was 0.17±0.091D(higher price group : 0.15±0.095D, lower price group: 0.19±0.086D). 3 out of 25 pairs met tolerance by IS0(±0.12D in ;::.:o.OOD and ~6.00D) which was very low02.0%), The average unwanted cylinder power was 0.15±0.060D(higher price group: 0.15±0.065D, lower price group : 0.16±0.058D). 4 out of 25 pairs met tolerance by IS0(±0.12D in ;::.:o.OOD and ~0.75D) which was also very low(16.0%). The average error from addition power was 0.08±0.073D(higher price group : 0.06±0.043D, lower price group : 0.10±0.085D). 18 out of 25 pairs met tolerance by IS0(±0.12D in :<=:4.000)(72.0%). For thickness, we could not evaluate comparing to ISO standard because the manufacturer did not specify the nominal value. It should not deviate from the nominal value by more than ±0.3 mm by ISO standard. The average thickness was 1.77± 0.187 mm(higher price group: 1.74±0.049 mm, lower price group: 1.80±0.237 mm). The higher and lower price groups and right and left lenses were significant statistica!ly in focal power, unwanted cylinder power, addition power and thickness(p < 0.05). From these measurements, we found only 1 pair of progressive power lenses(B-25-20 in higher price group) which met tolerance regulated by ISO. To meet ISO tolerances, more precise manufacturing process should be considered.

본 논문은 KS의 침입도 등급 체계에 대한 통계적 타당성을 검토하였다. 각 등급의 범위는 신뢰구간에 근거하여 설정되어야 하며, 최대한 인접 등급과의 중복을 피하도록 해야 한다. 그러나 통계적 이론에 근거해 검토한 결과 KS 침입도 등급 체계에는 각 등급 사이에 간격(Gap)이 없어서 범위를 벗어나는 것은 바로 다른 바인더의 등급을 침범한다는 점을 알 수 있었다. 따라서 많은 바인더 제품들의 침입도 평균값이 규정한계 내에 있을지라도 인접한 등급과 유사한 특성을 가질 수 있다. 또한 침입도 40-60, 60-80, 80-100과 같이 등급의 범위를 모두 20으로 규정한 것은 통계적 타당성이 없다. KS 침입도 등급은 각 등급 간에 간격이 없기 때문에 생산자는 제품의 품질관리 규정을 만족하기 위하여 ASTM 체계의 제품보다 변동계수를 더 낮게 유지해야 한다. 게다가 침입도평균이 상 하한선 쪽으로 치우친다면 재료의 품질 불확실성 때문에 바인더의 1/2 또는 그 이상이 인접 바인더와 중복된 것이다. 그러므로 KS침입도 등급은 통계적으로 타당토록 바로 수정되어야 한다.

Logistics is one of the most important factors to manage a stream of materials in economic environment. Establishing effective logistics system needs to consider some constraints which are fluctuation of materials volume, a long distance between makers and consumers, one way logistics and small quantity batch production. It is estimated that Unit Load System should be a powerful method to cope with those problems. It helps to realize the key issues which are Standardization and Logistics Pool System The Material Unification of Logistics System is able to participate in all kinds of industries including manufacturing, distribution and logistics. This system has some merits which are a long distance transportation cost down, product recovery, and treatment in the unbalance of demand and supply caused by unstable materials volume. Four strategies of Material Logistics Model are Packing Rationalization, Logistics Pool System, JIT System application and establishing effective infrastructure. The Material Unification Of Logistics System based on Unit Load System achieves efficiency of logistics and largely decreases moving cost.

국내산 렌즈제품들의 품질을 알아보기 위해서 국내에서 유통되고 있는 근시성 난 시 교정용 토럭렌즈들의 굴절력과 광학중심부 두께를 측정하고 분석하였다. 국내산제품들과 해외브랜드 제품간의 질적 차이는 거의 없었으나 국내산 제품 일 부분에서 허용기준을 벗어난 경우가 있었다. 본 결과들을 통해 볼 때， 국내산제품들이 해외시장에서 더 높은 경쟁력을 확보하기 위해서는 규격의 표준화를 통해 굴절력 및 두께에 의한 오차를 줄일 수 있는 엄격하 고 정멸한 품질관리 빚 공정관리가 요구되는 것으로 나타났다

This paper aims at designing an accelerated life test sampling plan for bulk material and showing its application for an arc-welded gas pipe. It is an integrated model of the accelerated life test procedure and bulk sampling procedure. The accelerated life tests were performed by the regulation, RSD 0005 of ATS at KITECH and bulk sampling was used for acceptance. Design parameters might be total sample size(segments and increments), stress level and so on. We focus on deciding the sample size by minimizing the asymptotic variance of test statistic as well as satisfying consumer's risk under Weibull life time distribution with primary information on shape parameter.
