Today, as a globalization continues and international trading blocks are formed, world markets are intensely competitive and abound in product variety, volume, complexity and environment. An environmental management system comprises the environmental elements of the overall management system. The basic input to a management system is information from stake holders, the operational system and the environment, the outputs are decisions and informations. Specifically, green comsumer's needs and expectations are changing and diversifying, resulting in a changed global environment for industry. Due to these changes, many companies are striving to achieve the ISO 14000 environmental management system certification. In this paper, I will present the strategy of environmental management, system strategy and continue to build a unique environmental management system by analyzing companies that will be achieved the ISO 14000 certification. After companies establish an ISO 9000 quality system these companies should focus on improve toward their own quality systems and continue to build ISO 14000.

Recently. together with consumers' increasing concerns on food safety and environmental issues. there is increasing demand on the environmentally friendly agricultural products such as organic products. At present, Japan. as a biggest net importing country of the agricultural products. is a market of the international-scale in the organic product marketing. Also. it is expected that the possibility of market expansion in the future is very high. According to the 2000 agricultural census in Japan. the number of the environment-friendly agricultural farmers were 501.556 householders. This number is about 145 percent higher than that of the 1996 results of 204,600 householders. Organic products in Japan were mainly marketed through the producer and consumer cooperation, producers' cooperation, specialized marketing company etc. However, along with the department store, big supermarket and others' participation in the market recently, the marketing channels are diversified. As of October 1999, market sales of the organic products were estimated about 350 billion yen. It is expected that organic certification system, organic products import, resturant industry scale and others will be more influential factors on the market expansion of the organic products in the future.

This paper empirically analyzed consumer price search behavior using Web log data of a Korean web site for price comparison. Consumer click-stream data of the site was used to test the effects of price level, product category, third party certification, reputation of retailers on click behavior. According to the descriptive statistics, 67.4% of shopbot users clicked the offer which was the lowest price returned in a search. We found that third party certification and reputation of retailers were significant determinants of clicking the lowest priced offer from legit analysis. We also applied Tobit regression analysis to estimate the price premium of the two determinants, but only reputation of retailers was found to have price premium of 4.9%.

Worldwide, Certification systems for standard of material and quality of product exist very variously. Korean industrial Standard (KS) is most representatively certification systems in Korea. But laboratory of korea uses often ASTM, RILEM and JIS and these standards do not get into unionization. so, Granted that experiment is same, result still can different. Therefore, this research measured chloride amount of hardened concrete using identical material and wished to improve accuracy of chloride estimation as that comparison evaluate to each examination.

The purpose of this study is to estimate efficiency of environmental-friendly agricultural product by using Data Envelopment Analysis. A proposed method employs a bootstrapping approach to generating efficiency estimates through Monte Carlo simulation resampling process. The technical efficiency, pure technical efficiency, and scale efficiency measure of strawberry by pesticide-free certification is 0.967, 0.995, 0.968 respectively. However those of bias-corrected estimates are 0.918, 0.983, 0.934. We know that the DEA estimator is an upward biased estimator. In technical efficiency, average lower and upper confidence bounds of 0.807 and 0.960. According to these results, the DEA bootstrapping model used here provides bias-corrected and confidence intervals for the point estimates, it is more preferable.

The purpose of this study was to investigate middle school students' perception of environment-friendly agricultural products (EAPs) and the degree of confidence about the certification mark. Questionnaires were distributed to 444 students of 6 middle schools located in Daegu, and a total of 416 responses were used for analysis. 28.6% of the respondents were using EAPs at home, and 62.0% of respondents didn't know whether to use EAPs at home. The 6 items representing the perception of EAPs were analyzed, resulting in 2 distinct dimensions-'benefits of EAPs' and 'attitude toward EAPs'. Regarding Benefits of EAPs, the score of 'EAPs better for health' was the highest, followed by 'EAPs have higher quality', 'EAPs were better for environmental protection', respectively. The proportion of students responded that 'the amount of pesticides should be reduced gradually' was 65.5% and only 3.4% for 'current level of pesticide use is not a problem'. There were significant differences between male and female students with regard to an interest in EAPs (p < 0.05) and opinion on the use of pesticides (p < 0.05), while no significant difference was found between groups with different education level of mothers. The respondents who use EAPs at home showed significantly higher scores with attitude toward EAPs (p < 0.001), and higher response rate for 'pesticides should not be used even if the price increases' (p < 0.05). Degree of confidence about the EAPs certification mark also affected students' perception of EAPs (p < 0.001). Our results indicate the importance of education for students on EAPs to enhance students' attitude towards EAPs and improve school meal satisfaction.

최근 인터넷 기술의 발전으로 인하여 사용자의 개인정보가 USB에 저장되어 사용되고 있지만 USB에 저장되어 있는 개인정보는 별도의 사용자 인증 과정이 필요없어 악의적인 목적으로 사용되어 개인정보가 노출될 수 있는 문제가 있다. 이 논문에서는 USB에 저장되어 있는 개인정보를 보호하기 위해서 개인정보의 이중사용 방지를 위한 USB 보안 프레임워크를 제안한다. 제안된 USB 보안 프레임워크는 서로 다른 네트워크에서 USB 보안 제품을 사용할 경우 USB 보안 토큰의 사용 유 무 및 사용자의 속성 정보를 인증 정보 앞에 추가하여 사용자의 인증 과정을 수행하기 때문에 통신 오버헤드 및 서비스 지연이 향상되었다. 실험 결과 단순파일 저장매체(USB driver)와 자체 연산 가능한 매체(USB Token) 보다 제안된 USB 보안 프레임워크가 패킷 인증 지연시간에서 평균 7.6% 향상되었고, USB수에 따른 인증서버의 처리량에서도 평균 9.8% 향상된 결과를 얻을 수 있었다.

This study examines the effects of consumer beliefs for food certifications on the behavioral intentions and the behavioral intention biases to purchase the certified seafoods by a subjective probability model which is on the basis of the mathematical probability model and the covariance model. The food certifications used on this study are 'Organic foods', 'Traceability system of food products' and. 'HACCP'. The representative foods of fishery products on this study is seasoned laver. The current study showed the following results. First, consumers have more than two different beliefs each for all certifications which are the subjects of this study. The beliefs of the certifications have an impact on the consumers when they consider to buy the certified seafood products. Second, consumers try to persuade by themselves to ensure that their particular belief about the certification could lead to a purchase the seafood products. Consumer beliefs of the "environmentally friendly production" on the organic foods certification is an important factor as much as the "guarantee of food safety" belief making a positive purchasing behavior intentions(PBI) bias for the organic seafood products. Consumers also have a positive PBI bias for certified seafood products in all certifications as long as a certification is considered to "guarantee the transparency of the food distribution process" as its belief. 'Traceability system' was the only one which didn't generate a positive PBI bias from the belief of "guarantee of food safety" out of three certifications.
