A new health paradigm may be evolving that would place emphasis on the positive aspects of diet, identifying components that are physiologically active and that contribute to the prevention of disease onset. It has been increasingly difficult to evaluate the impact of new bioactive materials and food products on the well being of society. Thus, testing systems for both health function and toxicity have become very elaborate, complex, and interrelated, making their interpretation difficult and open to controversy. To select the proper starting materials, to screen the appropriate health functionality and to determine the efficacy of product, a reliable, reproducible, sensitive and predictive assay is required. Particularly, in uitro assay is the first stage in preclinical test on physiologically active materials and have many advantages in terms of time, cost and convenience. However, several factors as well as some limitations should be considered in this assay system. This presentation, therefore, will address the use of in uitro assays for evaluating physiological functionality of foods coupled with general consideration.

The publication International Standard Banking Practice for the Examination of Documents under Documentary Letters of Credit (ISBP) is the product by a task force of the ICC Banking Commission. The ISBP is a practical complement to UCP 500, ICC’s universally used rules on documentary credits. The ISBP does not amend the UCP. It explains, in explicit detail, how the rules are to be applied on a day-to-day basis. It fills a needed gap between the general principles announced in the rules and the daily work of the documentary credit practitioner. By using the ISBP, document checkers can bring their practices in line with those followed by their colleagues worldwide. The result should be a significant reduction in the number of documents refused for discrepancies on first presentation.

Value can be defined as function divided by cost. The ultimate goal of VE (Value Engineering) is to simultaneously reduce cost and to enhance function in given projects. In general, there are eight phases (Selection, Investigation, Speculation, Evaluation, Development. Presentation, Implementation, and Audit) to perform VE. This paper presents analysis of important factors for VE in construction fields using QFD (Quality Function Deployment) technique. QFD was introduced in 1972 to help design supertanker in Mitsubish's shipyards in Kob, Japan and formally defined by the American Supplier Institute in 1987 as a system for translating consumer requirements into appropriate company requirements at every stage, from research, through product design and development, to manufacture, distribution, installation, and marketing, sales and services. The objective of this paper is to provide and analyze the trend on the viewpoint of efficient value engineering of field workers. The data are collected by questionnaires. The samples for this study are chosen from 13 companies in Korea during 2 months (2002. 7 ∼ 2002. 8). The results of this study will play an important role not only for the efficient value engineering but also for preparing of life cycle cost analysis.

This study was performed in an effort to standardize the quality of fresh-cut products. Here, consumers' perceptions of fresh-cut products were surveyed to determine the quality factors in preparing quality standards for fresh-cut products. According to the surveys, freshness was the most important factor for consumers when choosing fresh-cut products at the market. Secondary indicators of good quality, i.e., "sensory qualities," were determined to be vibrant color, clean taste, nice feel, neat presentation, etc., as well as knowledge of whether it was organically grown. Off-odors decreased a product's marketability. Likewise, the more wilted or brown it appeared, the less a product was desired. From the results, the quality control indices for fresh-cut products were derived as freshness, discoloration, off-flavor, uniformity, prohibition of adulteration by alien substances, packaging and labeling. The quality of fresh-cut lettuce samples was measured against three storage temperatures: $20^{\circ}C,\;10^{\circ}C$ and $5^{\circ}C$. Sensory quality evaluations revealed the following: produce stored at $20^{\circ}C$ lost its marketability in less than one day; produce stored at $10^{\circ}C$ lost its marketability in less than two days; on the other hand, produced stored at $5^{\circ}C$, maintained its marketability for six days. At these respective points, browning started to occur around cut areas, and increased gradually once it began. Vitamin C content decreased with storage time, but storage at $5^{\circ}C$ maintained vitamin content the longest duration. Finally, further examinations were performed on the sensory qualities of fresh-cut lettuce samples at four levels of increased browning. Up to the third level, the product score for marketability was 5.6.

Unlike traditional advertising practice, product placement(ppL) has several advantages such as avoiding zapping and working as celebrity endorsement. Previous research has been mainly focused on the presentation style of the PPL. However, to understand the effect of the PPL process properly, it is necessary to study the audience's personality. Therefore, this study attempted to investigate the relationship between audience's consumption tendency and the effect of the PPL. More specifically: the current study examined the influence of the brand consciousness and impulsive buying tendency on the attitude toward the PPL. The results showed that people considered to be highly brand conscious and impulsive buying tendency seem to have more favorable attitude toward the PPL. Indeed, self-esteem have a positive influence on the attitude toward the PPL. Therefore, consumer's personality is related to their response to the PPL.

As electronic commerce establishes itself as a viable and competitive channel, this research compares the attractiveness of online and offline purchase from a transaction cost perspective. In the process, we propose a framework that integrates transaction cost with purchase decision process and product type. Specifically, the paper proposes and tests hypotheses regarding the difference between online and offline channels with respect to the transaction costs incurred in each stage of the purchase decision process. These differences are further compared across different product types categorized according to the FCB Grid. A total of 24 hypotheses were tested by conducting a questionnaire survey on university students. The results showed that 19 out of 24 hypotheses were supported. Following a detailed presentation of the analysis results, the paper concludes by discussing the academic and managerial implications of the findings.

Internet websites are excellent resources for younger people to gain information related to breastfeeding. So in this study, we evaluated the breastfeeding knowledge of university students, as well as the currently available website information on breastfeeding. Among the criteria, the six most important evaluation categories for the breastfeeding information on websites were selected and identified. The study participants completed the modified Williams and Hammer's tool, in order to evaluate their breastfeeding knowledge. An additional tool took into consideration the website breastfeeding information criteria, to evaluate the Korean websites. This 34 item tool was categorized into milk supply, comfort during breastfeeding, health of the baby and mother, social support, presentation of message, and products or financial motivation. Thirty-seven websites related to breastfeeding were evaluated, and the results were then discussed by nursing students. The students in this study were not knowledgeable on breastfeeding management with regard to the expression and storage of breast milk, the prevention and care of sore nipples, or use of breastfeeding aids. The breastfeeding information found on the Korean websites received positive evaluations for milk supply, comfort during breastfeeding, and health of the baby and mother. However, the educational content on social support, the message presentation, and the product areas on websites were rare or required additional information from breastfeeding specialists. In conclusion, based on our empirical survey, we need to design websites and evaluation tools for accurate website information regarding the social and economic benefits of breastfeeding, so that Korean women are better motivated to breastfeed by the information they obtain through the Internet.

Soil and groundwater contamination by petroleum hydrocarbon products is only one of many environmental problems in Korea. However, many environmental consulting companies have been targeted their business on this subject because the petroleum-oil-lubricant (POL) products have been widely used product and accidental releases of the products from storages resulted numerous small and large contaminated sites throughout Korea. Therefore, many small and large companies are actively participating in environmental assessment and remediation projects for the POL contaminated sites. Remedial technologies for the POL contaminated sites have been developed for many years by government and private institutions throughout the world. Development of a new decontamination technology for the POL contaminated sites is no longer attractive issue in research community because scientific bases of most cost-effective remedial technologies are well understood and have been used in the field by commercial sector. Numerous sites contaminated by underground tanks at gas stations have been remediated by relatively small companies in this country. We should appreciate their noticeable contributions as a frontier under very difficult market environment in Korea. We heard many successful stories as well as a few failure stories. Soil-groundwater remediation of POL contaminated site is not a simple task as shown in the text books or protocols. Therefore, failure risk is always with us, which requires continuous efforts for improvement of the technologies by the users and developers. In this presentation, author will discuss technical problems encountered and improvement made during implementation of several remedial technologies applied by Samsung Environmental Team. This is not a presentation about research or case study. We want to share our thought and experience with environmental engineers actively engaged in soil and groundwater remediation projects in Korea.
