The purpose of this study is to develop a fashion show model as a local festival program by designing the costumes of Chosun dynasty from later 16th century to early 17th century and planning a fashion show. The designed costumes are based on the life of the representative poetess, Maechang Lee, from Buan-gun, Jeollabukdo. The planning of the fashion show consists of seven stages, that is, finding a theme, composing the story, designing costumes, choosing music, planning intermission events, producing visuals and booklet, and directing model performances. This paper focuses mainly on finding a theme, composing the story, and designing costumes.

This study examines a normative model of project management systems, PPMS, to provide information for directing R&D activity in order to increase R&D productivity. The PPMS (Project Process Management System) is a disciplined and systematic framework to manage R&D projects effectively and efficiently under the assumption of a strategic decision making and long-range planning. The purpose of PPMS is to provide for the management of research organization at different levels an effective management tool; first, for the planning system which deals with rational selection and authorization of R&D projects, second, for the control system which concerns monitoring and controlling the execution of R&D projects, and finally, for the evaluation system which attains evaluation of the performance results of R&D projects and determination of the necessary follow-up. A view for the future development of project management within the context of a project-performing organization is also elaborated to exhibit the progress and phase description of the project management system.

This paper introduces a conceptual design of a combined scroll expander-compressor unit for a fuel cell. Since air discharged out of the fuel cell stack has still high pressure energy, some power can be extracted from the air by directing it to pass through an expanding device. Such extracted power can be used to drive an auxiliary compressor. For this purpose, a scroll type expander coupled to a scroll type compressor was designed for a 1kW-class fuel cell. The orbiting scroll members of the expander and the compressor were made to share three of common drive shafts installed in the mid frame plate. Performance analysis for the combined expander-compressor unit showed that the installation of this unit could reduce the auxiliary power consumption in the fuel cell by about 42%.

Al-MCM-48 molecular sieves (Si/Al = 25, 50, 75 and 100) were synthesized hydrothermally using cetyltrimethyl ammonium bromide as the structure directing template. The orderly arrangement of mesopores was evident from the low angle X-ray diffraction patterns and TEM images. The catalytic performance was evaluated in the vapour phase isopropylation of phenol with isopropyl acetate. Phenol conversion decreased with increase in the Si/Al ratio of the catalysts. The major reaction product was 4-isopropyl phenol (selectivity: 78%). Delocalization of phenolic oxygen electron pair over the aromatic ring promoted para-selective alkylation. Such delocalization could be aided by the hydrophilic surface of the molecular sieves. Though ester was used as the alkylating agent, phenyl isopropyl ether was not formed

An understanding of biomaterials' smart properties and how biocomposite materials are manufactured by cells provides not only bio-inspiration for new classes of smart actuators and sensors but also foundational technology for smart materials and their manufacture. In this case study, I examine the unique smart properties of bone, which are evident at multiple length scales and how they provide inspiration for novel classes of mechanoactive materials. I then review potential approaches to engineer and manufacture bioinspired smart materials that can be applied to solve currently intractable problems such as the need for "smart" body armor or decor cum personal safety devices.

Mesoporous ethanesilica thin film was prepared using PEO-PLGA-PEO triblock copolymers as structure-directing agents and (1,2-bis(triethoxysilyl) ethane BTESE; bridged organosilicates) as inorganic precursors via one-step sol-gel condensation of ethanesilica precursors. The mesostructure of ethanesilica films is critically dependent on the processing experimental parameters after the hydrolyzed silica sol mixture was spin-cast. This study examined the effects of the block copolymer template/organosilica precursor ratio in the casting solution and aging period before calcination of the mesostructure. It was further demonstrated that mesoscopic ordering of organosilicate thin films is induced by the rearrangement of block copolymer template/organosilica hybrid during thermal decomposition of the PEO-PLGA-PEO triblock copolymer. The mesoporous structure and morphology were characterized by SAXS, TEM and solid-state NMR measurement.

Electrical resistivity, self-potential and time-domain induced polarization methods were conducted for study of electrical responses on vein-type sulfides ore, which is intruding limestone and dolomite of Ordovician, of Geumpung mine located in Dojeon-ri, Susan-myeon, Jecheon-si, Chungbuk. Sulfides bearing chalcopyrite, pyrrhotite and galena etc. are deposited in disseminated or vein-type. Good result that resistivity and self-potential surveys detect high grade-estimated mineralized zone located in upper part of existing low grade ore zone is acquisited and is to some extent consistent with induced polarization. Furthmore, a new mineralization zone directing EW is detected.

In the more than one decade, studies of organizational citizenship behavior(OCB) have increased continuously, research on the role of job satisfaction and organizational commitment upon the relationships between OCB and Job characteristics, however, is very scarce. This study analyzed comprehensively existing studies of OCB, designed a model of mediating role of behavioral performance(job satisfaction, organizational commitment), and generated three hypotheses inherent in the model. To design the model and generate the hypotheses, this study conducted a comprehensive literature survey on OCB. To test the hypotheses, this study collected data from 847 employees at 12 large general hospitals in Pusan area through a questionnaire survey and conducted the three step mediated regression analysis using the SAS-PC Package. Conclusively, job characteristics tend to be the most influential antecedents affecting not only through mediating factors but also directing to OCB. These and other major findings from this study imply that existing American studies may be applicable the Korean organizations and that this study may complement the deficiencies of the existing studies.

This paper is to introduce assorted features of a four-week English Immersion Program managed by Hongik English Language Institute for the first time in summer 2000. The program was aimed to provide English learners with the English simulation environment where everything was supposed to be English only. Thus being exposed exclusively to the English surroundings the clock around, the learners who had not had enough opportunities to use the language were able to attain a high motivation for speaking English, which eventually led to the increase of their general English language proficiency. Presenting merits and demerits of the curriculum and the overall management of the program, this paper plays a role in directing the program in a more improved way for the future and giving guidelines to other institutes where similar programs are under consideration.

Objective: The purpose of this study was to examine the differences between mothers' and grand mothers' picture book reading behavior with children of ages 2 and 4. Methods: Participants were twenty 2 year olds and their mothers/grandmothers as well as twenty 4 year olds and their mothers/grandmothers. Forty pairs of children/mothers and children/grandmothers, respectively, were videotaped as they shared reading a picture book together. Data were analyzed with descriptive statistics, mean, standard deviation, and two-way ANOVA test. Results: Results indicated that mothers' and grandmothers' picture book reading behaviors were significantly different in verbal behavior. Mothers performed more explanation and questioning, while grandmothers performed more limitation, directing, and correcting. As far as non-verbal behavior is concerned, mothers used more physicalgestures, pointing, descriptive gestures, and imitative gestures, whereas grandmothers requested certain actions. Conclusion/Implications: These findings have implications for the importance of the mothers'/grandmothers' roles in shared picture book reading with the child.
