With Zohar(1980)'s research on safety climate and industrial safety, occupational safety and health literatures begin to emphasize the influence of organizational context. Based on this research trend, this paper tried to review the relationship between i

Nanotechnology represents a new frontier in science and technology with long term goals and benefits. Nowadays, nanotechnology is producing many revolutions and applications such as quantum computing, surface and materials modification, novel separation and sensing technologies, and human biomedical replacements. These new techniques are being introduced in food and bio filed. In this review, the status and trends related to nanocomposites, nanoparticles, nanotubes, delivery vehicles and biosafety were reviewed. The situation of funding of nanotechnology research in USA, Japan and Korea is also summarized.

식품산업체에서 검사한 자료의 일반세균수는 대부분 불규칙 분포를 나타낸다. 최근 이러한 불규칙적인 경향에 대하여 미생 물수의 lognormal 분포 특성을 이용하는 확률분포 모델을 적용함으로써 좀더 정확한 변화의 특성을 밝히고 있다. 확률분포 모델을 이용하면 일반세균수와 대장균군 등의 분석결과에 대해 과거의 단순한 경향분석을 벗어나, 유용한 분석이 가능한 것으로 나타나고 있 다. 본 연구는 냉동만두류를 생성하는 2개 업체의 각각 1년 동안 실험된 일반세균 자료를 갖고, 확률분포 모델 활용의 타당성과 업체간의 위생수준 상호비교 그리고 예상되는 위해 발생 예측에 적용 검토하였다. 그 결과 정량적인 미생물 자료에 대한 확률분포 모델의 적용은 식품산업체에서 일반세균수에 의한 위해발생 가능성을 예측하고 안전관리 수준을 결정하는데 유용한 것으로 판단되었다.

Today, the size of a parcel delivery service market, which is a part of logistics, at home and abroad has been extended rapidly and its growth rate is expected to increase hereafter. At this point, when service is applied strategically in a parcel delivery service, we need to understand the feature of logistics service quality by view of customer differentiation. In this study, we try to constitute a model of the feature of logistics service, which is combined five features of service quality (Responsiveness, Empathy, Reliability, Accuracy and Tangibility) based on measuring model of SERVQUAL with logistics service, and to know the feature of logistics service from parcel delivery service by jobs with statistical tool.

This paper is for standard of South and North Korea clothing, especially size. It is analysis and make a comparative study of KS K 0050-0052 which is South Korea industrial standard and KPS 8477.1~3, 8477.6, 8477.9, 10253 which is North Korea's. With this

In the electrode fabrication of unit cell, it was ascertained that electrochemical characteristics were greatly increased with 90 wt.% of BP-20, 5 wt.% of Super P and 5 wt.% of mixed binder [P(VdF-co-HFP) : PVP =7 : 3] The self-discharge of unit cell showed that diffusion process was controlled by the ion concentration difference of initial electrolyte due to the characteristics of Electric Double Layer Capacitor (EDLC) charged by ion adsorption in the beginning, but this by current leakage through the double-layer at the electrode/electrolyte interface had a minor effect and voltages of curves were remained constant regardless of electrode material. The electrochemical characteristics of 2.3 V/3,000 F grade EDLC were as follows: 0.35 m of DC-ESR (100 A discharge), 0.14 mof AC-ESR (AC amplitude 100 mV), 2.80 Wh/kg (3.73 Wh/L) of energy density and 4.64 kW /kg (6.19 kW/L) of power density. Power output was compatible with electric vehicle applications, uninterrupted power supply and engine starter, in due consideration of Ragone relations.
