A long-term energy system in the future is expected to be based on the ideal circulation system between water and hydrogen in the sense that the hydrogen prepared from water eventually returns to water again after its use. Currently, with respect to the hydrogen energy system, it is predicted that the turning-point at which the production cost of hydrogen will become to be lower than that of fossil fuels would be after 2010. However, fuel cell technology would be able to be practically used for the applications to the transportation vehicles and small-scale power sources from 2004, and therefore, an efficient construction of the infrastructure covering hydrogen production and supply systems would be required with short-/mid-term technologies for the $CO_2$ reduction associated with fossil fuel utilization. In this paper, the hydrogen quantity available in domestic market has been estimated focusing on the hydrogen by-produced from domestic industries, and also the infrastructure for hydrogen-driven vehicles like fuel cell cars has been reviewed.

Since the global financial crisis, funding for startups or ventures has been diminished seriously. In this situation, crowd-funding has attracted worldwide attention as a viable means to financing startups/ventures. After reviewing existing laws in other countries, this study investigated the current status of crowd-funding legalization in Korea and surveyed requirements from three groups of participants to crowd-funding. Investors already recognized the high risk of crowd-funding into startups and asked for the protection of their investment. But, their priorities were on the enlargement of tax benefits and the establishment of a trading market for selling their equity. In addition, investors wanted to shorten the compulsory holding period. Issuers as fund raisers hoped fast legalization, convenient process of crowd-funding, and expansion of government support. Crowd-funding platform operators requested policies for establishing paths to become new growth companies from startups, tax benefits, and the setup of separate fund for startups. Currently, the National Assembly in Korea is holding the discussion on the submitted law. For desirable outcomes to all participants, it would be better to proceed in the following sequence. First, legalize the crowd-funding with clauses protecting investors; Second, encourage investment through tax benefits; Third, develop communities among participants for reducing information asymmetry; And fourth, establish diverse trading markets for selling equities of startups.

Six Sigma has been one of main quality improvement approaches since Motorola first invented Six Sigma in 1987. Many scholars and consult experts have discussed the critical success factors of implementing Six Sigma management, but most of them are based on related theories or qualitative analyses. In the paper, we first review critical success factor of Six Sigma status quo based on literature. Then we design the questionnaire and survey China manufacturing enterprises that have introduced Six Sigma management. And finally, we analyze the critical success factors of China manufacturing industry implementing Six Sigma management by using structural equation model and find that leadership and Six Sigma strategy, focus on market and customer, evaluation and motivation, selecting, managing and implementing Six Sigma projects are four critical success factors of China manufacturing enterprises implementing Six Sigma management. At the same time, the paper also presents the relationships between the critical success factors. The results are of important role in China manufacturing industry locating resources, eliminating waste and improving Six Sigma performance.

Since the introduction of a new field of skin care to Korean market which was developed in 1980, a variety of skin care therapies have appeared in mid-1990s. Therefore, in particular, it is considered that aroma therapy is one of the most preferred methods for skin care. Therefore, previous studies focused just on clinical effects of aromatherapy while this study focuses on aestheticians by identifying whether performance of aromatherapy, and their contribution to income will influence on satisfaction in aestheticians and customers' intention to reuse aromatherapy service for positive demonstration. The results of the study are presented as follows: First, it is demonstrated that side-effect of aromatherapy, contribution to income, and customer satisfaction have significant effect on professional aestheticians. In particular, in respect to the aestheticians, this study obtains the results rather different from the estimation that customers are satisfied with the professional service though they have side-effect. Second, as the satisfaction in professional aestheticians after skin care service is a significant factor that influences on intention to reuse it, this study concludes that re-management on behaviors is required according to the degrees of satisfaction.

Silk Industry doesn't have enough strategic ability to plan the product for internal and external strong competition and global luxury trend in Jinju. To provide silk fashion planning information and planning method, this study investigated the fabric planning system, such as product system and problems, the method of seeking information, via questionnaires for 68 Jinju silk companies. The results were that the Korean traditional garment, Han-bok and lining of that were given more wight in Jinju Silk for domestic, and the next, neckties. These silk had produced by OEM and didn't have almost my planning ability, but nowadays buyers wanted to get some planning ideas from manufactures, not giving any planning guideline before production, more and more. For Jinju Silk Fabric Companies, planning direction of silk fabrics of vision were needed, that had to be adaptable to manufacture situation and applicable to market.

As flexible manufacturing systems (FMSs) are highly automated and required flexibility to satisfy market need, dispatching rules are constrained by specific environments of manufacturing systems such as mechanical failures, absence of employees, and lack of spare parts. In this paper, an ontology-based knowledge approach is proposed to improve efficiency of system through adapting suitable dispatching rules, considering context in a FMS shop floor, which consists multiple manufacturing cells. the multi-agents monitor manufacturing system status and job so that it figures out a dispatching rule considering context. To demonstrate the proposed approach, a proof-of-concept prototype system has been implemented in the $JADE^{TM}$ platform and Protege to make OWL DL ontology.

Domestic remodeling market is now growing centering around non housing building. Unlike non housing building remodeling business, understanding of remodeling demanders accustomed to profit of reconstruction, deficiency of experience performing remodeling project and construction, shortage of will performing remodeling policy and detailed action method are difficulties in performing apartment building remodeling business. Understanding change of remodeling demanders. strong economic incentive by government, construction management paradigm shift from new construction into building life cycle, application of construction method using existing building condition before remodeling and remodeling related industry infrastructure are required to improve this remodeling business circumstances.

Recently, utilization of PMIS(Project Management Information System) is in high demand as it is desired to advance the construction market through cost reduction and quality improvement within the given schedule. However, PMIS developed by individual projects are mostly evolving around construction progress status due to the temporary nature of development period and use of the system by project executers is no more than perfunctory that results in limiting the effective communication between the project owner, project manager and constructor. Therefore, the purpose of this paper is to review the PMIS developed so far, and present the direction for an effective PMIS.

This research investigated the purchasing behaviors of fur clothing consumers to verify fur clothing consumption and to establish marketing strategies for the fur clothing market. Since fur clothing has clear characteristics distinguishing it from other clothes, there are many differences in customers' interest. Therefore, it is needed to identify some differences in the customers' interest by their own buying habits. A survey was conducted with a questionnaire and revised by using a theoretical background. Questionnaires were given to 322 ladies in their over 20s. SPSS 12.0 was used to analyse the result with analysis of frequency, a primary factor, crossing, cluster and ANOVA. There were several results as follows. First, purchase behaviors of fur clothing were significantly different between groups divided by demographic variables such as marital status, age, and income level of household. Second, factor analysis on sought clothing benefits resulted in 4 dimensions such as symbolic value, brand value, economical value and practical value. Cluster analysis on the 4 factors of clothing benefits being sought resulted in 3 groups such as one group pursuing symbolism, one group pursuing practicism/economism and a group pursuing brand. Third, purchase behaviors of fur clothing and demographic variables were significantly different between the groups divided by clothing benefits being sought.

During the past two decades, China has seen her great progress in plant biotechnology. Since the Chinese market of herb medicine is huge, while the plant resources are shrinking, particular emphasis has been placed in plant tissue and cell cultures of medicinal plants, this includes fast propagation, protoplast isolation and regeneration, cell suspension cultures and large scale fermentation. To optimize culture conditions for producing secondary compounds in vitro, various media, additives and elicitors have been tested. Successful examples of large scale culture for the secondary metabolite biosynthesis are quite limited : Lithospermum ery throrhizon and Arnebia euchroma for shikonin derivatives, Panax ginseng, P. notoginseng, P. quinquefolium for saponins, and a few other medicinal plants. Recent development of genetic transformation systems of plant cells offered a new approach to in vitro production of secondary compounds. Hairy root induction and cultures, by using Ri-plasmid, have been reported from a number of medicinal plant species, such as Artemisia annua that produces little artemisinin in normal cultured cells, and from Glycyrrhiza uralensis. In the coming five years, Chinese scientists will continue their work on large scale cell cultures of a few of selected plant species, including Taxus spp. and A. annua, for the production of secondary metabolites with medicinal interests, one or two groups of scientists will be engaged in molecular cloning of the key enzymes in plant secondary metabolism.
