Several emergy researches have been carried out to estimate the value of marine ecosystem services in Korea over the last decade. Their results cannot be compared mainly due to inconsistency in emergy-money ratios used to convert emergy unit into monetary unit. This study aimed at providing a standardized format for the emergy evaluation of the Korean economy and environment for different emergy evaluations to be compatible. Even though the area of the continental shelf increased in this study compared to those of previous studies, areaweighted average tidal range for the entire continental shelf of Korea resulted in smaller tidal range, decreasing the final emergy input from tide. However, emergy inputs from nonrenewable resources and purchased goods and services increased with new categorization and use of more detailed data, combined with updated unit emergy values. This led to higher emergy-money ratio for the Korean economy, indicating that previous emergy valuations might have overestimated the contributions of marine ecosystem to the real wealth of the Korean society. The base year for gross domestic product used in the emergy evaluation needs to be clearly indicated due to its impact on the calculation of the emergy-money ratio. A standardized emergy table for the Korean economy will contribute to ensuring consistency among future emergy researches on the valuation of marine ecosystem services.

Recently, Korean government promotes BTL(Build-Transfer-Lease) for their public construction project to apply private sector's experience and finance initiatives. Many of public buildings and civil infrastructure projects were planned to be delivered by BTL and it helps to continue public projects under tight budget conditions. Since the characteristics of BTL projects, creative ideas for the project function, performance and its LCC (Life Cycle Cost) become more important than usual public work project. This paper introduces the systematic "VE job Plan" application techniques for BTL project and shows the process. This study shows the application of "VE job Plan" for BTL project to help decision making and value improvement. Also, Project cost was estimated by LCC (Life Cycle Cost) analysis. Technical "FAST diagram"was developed and used to find major functions of the project. So, it helps to improve performance of functions and make creative ideas. FAST diagram also help to find relationships between functions and cost. A case study (Daegu Art Gallery BTL Project) was conducted using proposed "VE job Plan. Study demonstrates how value management helps save money and increase functional performance. Researcher found that project can save cost and improve performance of functions significantly by using appropriate VE analysis process at appropriate time.

Patents have been recognized as a core knowledge asset which are closely related with company's technological competitiveness. However, only a small portion of patents are actually contributing to the profit of the company. In addition, it costs a lot of money continuously to maintain the patent rights regardless of their values. Thus, effective methodologies are required to create patents with high values. It is examined what kind of differences exist between high value patents and the others in the use of TRIZ methodologies. For the purpose, we analyzed the US granted patents of Samsung Electronics. The analysis shows that there is no significant difference in the use of inventive principles, but high value patents utilize 'separation by condition' the most where as the others 'separation by space' the most frequently in the use of separation principles. In the use of standard solutions, high value patents use the 'class 2' principles frequently than the others.

The Nobel Prize, which began in 1900, has already produced more than 1,000 winners worldwide. However, South Korea has failed to produce a Nobel Prize winner in the field of science. In order to make the Nobel Prize possible in science, many concerns and improvements are needed in many ways, including scientific administration, bureaucracy, and public education. In the field of science administration, authoritarianism seem to be a major stumbling block. Developing scientific technology by policy means and achievement of scientific technology to make money are not healthy foundation for the Nobel Prize. School education to enhance the value of creativity and challenge in needed. Social awareness is needed to value creativity and challenges. Acceptance of fails is required to succeed. It can make money to study things that don't pay. The Nobel Prize can be approached without the recognition of the Nobel Prize.

This study was taken to increase efficiency in reviewing documents of school facilities from the network of ERIV(Educational Resources and Information Center, USA). Outline of the ERIC network, and the structure, role, function of the ERIC thesaurus are introduced. A thesaurus have developed for information retrieval purpose provides the filing labels which permit information to be stored by one person and retrieved by another. As an information system grows, its thesaurus is systematically built and refined to the point where it represents, in a very special sense, the vocabulary of subject field. The Thesaurus of ERIC Descriptors represents such a vocabulary for the field education. An understanding of its origins, its function and its limitations, is just as important to the teacher, the student of education or the educational researcher as it is for the indexer or custodian of the information pool it represents. If the Thesaurus is understood and used in an appropriate way, it can give all educators not only insight into the ERIC system but also an increased awareness of the language of their field. A great many terms are necessary to describe the many aspects of education, and the task of relating them in even an approximately consistent way is an enormous one. The undertaking should be managed by people who not only know what they are talking about but who also should be able to predict what people in their field are lilely to be talking about in the near future. It should also enlist people who are willing to pay term to another within the system. To engage a large number of these two kinds of people over a long period of time is very likely to cost a great deal of money. There is very little proprietary value in producing such a list of terms, for it can very easily be copied, adapted, updated, etc. Thus, because of its high cost and low proprietary value, it becomes a task likely to be funded only by a government. A government has many ways of spending its money. However, after the decision has been made to spend money to produce an authority list, one must decide how this authority is to be delegated. The history of the development of the ERIC Thesaurus is the history of how this authority was delegated. Scientific research has thrived on efforts to define terms as precisely as possible. It is difficult to say with certainty, however, that solutions to social problems have thrived on a simple diet of scientific research. Contemporary crises demand new and imaginative ways of conceiving problems and talking about them. If this Thesaurus or any other scheme for normalizing or controlling language inhibits in the slightest measure the creative use of language, it is against it use. Only if the principles and details of the Thesaurus are misunderstood can it be used as a constraint on language in a negative sense. Students of education of every kind should see the The-saurus as an opportunity to become increasingly self-conscious about their language and thus about their assumptions and their approaches to educational problems.

The objective of this paper is to apply choice experiment methods to estimate non-market value of organic farming and its policy implication. A preliminary survey shows that the attributes of organic farming are reduce environmental pollution, bio-diversity improvements, cultural diversity improvements and maintain local community, reduce green-house gas emissions, energy saving, landscape improvements and tax for organic farming improvement policy. Questionnaire was eight different choice sets presented to each respondent. Implicit values of the attributive levels of organic farming have been calculated into tax money costs per house. This paper compared the six feasible scenarios in terms of willingness to pay per year. This study is expected to contribute to government's organic farming policies and quantitative information related to practice of organic farming.

Over the last several years, Korea has increasingly adopted design-build for public construction projects. There is a much greater awareness of the need to change to a system based on 'Value for Money', which is high on the government's agenda. A whole life performance bid evaluation model is proposed to aid decision makers in the selection of a design-builder. This is based on the integration of a framework using an analytic hierarchy process, as the bid awarding system is being changed from one based on the lowest price to one based on best value over the life-cycle. Key criteria such as whole life cost, service life planning and design quality are important through the key stages of the evaluation process. The model uses a systematic and holistic approach, which enables the public sector client to make better decisions in design-builder selection, which will deliver whole life benefits based on long-term cost-effectiveness.

The objective of this study is to measure self-image of adolescence, analyze empirically clothing-purchasing-behavior of adolescence and clarify correlation of two variables, self-image and clothing-purchasing-behavior. For this purpose, the techniques involve theoretical studies and researches based on historical obtained from previous related studies and surveys, 431 high school female students who reside in Seoul are asked to answer selected survey questions to examine three aspects, clothing-purchasing-behavior, self-image and demographics. The evaluation of surveyed information is analyzed by statistical techniques to improve the accuracy of data. Statistical methods used are as follows; Descriptive(frequency, mean, percentage), Factor Analysis(varimax rotation), Crosstabs(Chi-square), T-test, One-Way ANOVA< Correlation Analysis, Reliability Analysis and Duncan's Multiple Range Test. The mjor results of this study were as follows: Firstly, there is a discrepancy between real self-image and ideal self-image. Furthermore more significant differences is seen from physical aspects than psychological aspects. Consequently, research proves that the difference derived from their ideal situation and real situation leads to psychological unstableness. In addition, making their real self-image is dependent upon several elements such things as family economic level, pocket money, expenditure on clothing. Therefore, it is critical to combine all factors in order to decide how much to spend for children's clothing and pocket money in parents point of view. Secondly, research shows that shows hat there is correlated relationship between average expenditure on clothing and presence of mother's job. Average expenditure on clothing is, generally, influenced by vogue which is tend to be changed seasonally. It, also, shows that there is positive linear regression between expenditure on clothe and sensitivity for vogue. That is to say, dependent variable, expenditure on clothing, is varied as independent variable, sensitivity for vogue, changes. Female high school students are likely to give much value on brand. Moreover people who are spending more money on clothes have higher tendencies in prompt purchases than who are not. Thirdly, the analysis of clothing-purchasing-behavior and self-image shows that the difference between real self-image and ideal self-image draws the main reason of dissatisfaction after purchase of clothes. As a consequence, their unfilled needs lead them to keep making another purchase to satisfy themselves. Therefore, it is strongly recommended that parents' advices and directions on their children's money spending on clothes are imperative to establish well-behaved purchasing patterns.

The purpose of this study was to examine the work values of undergraduate-level foodservice major students. In order to assess work values of the participating students, this study adopted 'Maryland Work Values Inventory'. Data from a total of 290 surveys were collected. The participants consisted of 146 commercial foodservice major students and 144 institutional foodservice major students. Among the seven work values, both groups ranked 'job advancement' as the most important work value. Commercial foodservice major students rated 'altruism' as the least important work value, whereas it was 'stimulation' for institutional foodservice major students. 'Need for work' was evaluated statistically higher by junior and senior students compared to sophomore students of commercial foodservice major (p<0.05). In both foodservice majors, a positive relationship was found between work value scores and grade levels. All work value scores tended to be higher for students in higher grades. This tendency was especially statistically clear for the value 'need for work' for commercial foodservice major students and 'money and prestige' for institutional foodservice major students (p<0.05). There were some gaps in the work values between students with different career field choices. For the commercial foodservice majors, those interested in fine dining perceived 'satisfaction and accomplishment' and 'altruism' as more important [4.33 (p<0.05) and 4.05 (p<0.01), respectively] compared to students who had interests in fast food restaurants (4.06 and 3.67 respectively). Scores for 'satisfaction & accomplishment' (p<0.05), 'money & prestige' (p<0.001), and 'stimulation' (p<0.001) were significantly different among institutional foodservice major students. In addition, students more interested in industrial foodservice field regarded 'money & prestige' and 'stimulation' as less important as indicated by noticeably lower scores (3.74, 3.55 respectively) in comparison to the other group (p<0.001). The results of this study, which explored foodservice major students' work values, suggest that there is an increased need for the students to build up their work values as well as for the foodservice industry to offer appropriate work values to future foodservice employees.

Micropayment is an electronic payment system for small value transaction. It needs to use a little amount of resources, such as communication and computation due to its small value. In other words, the processing cost for the micropayment must be less than the value of the payment. Several kinds of transactions are suitable for micropayment, eg. the purchasing of train tickets or digital newspapers. Since micropayment systems are designed for small-amount payment the key factor for any micropayment system design is believed to be the minimization of resource consumption without compromising the standard security. In this paper, we propose an adaptive agent approach to credit-based micropayment system, which employs the concept of dynamic balancing between the resource consumption and the risk in the system. As a result of the dynamic balancing, our system not only solves the problem of global overspending but also uses fewer amount of resources than existing approaches. Our approach limits the amount of money spent by untrusted customers to all merchants. Thus, our approach provides a boundary of the global overspending. In addition, for trusted customers, our approach requires less scale of communication for verifying authorizations than all existing approaches.
