최근 중요시되고 있는 환경친화적 서비스의 평가를 위해서는 경제적 영향과 환경적 영향 사이의 유기적인 관계가 고려되어야 한다. 하지만 기존 연구에서는 주로 경제적 가치측면만이 고려되었고, 환경적 영향과의 연관관계를 고려한 연구는 상대적으로 많이 이루어지지 않았다. 본 연구는 환경적 영향에 대한 경제적 가치를 판단하는 에코효율성(Eco-efficiency)을 환경친화적 서비스의 평가지표로서 사용하고, 이를 DEA(Data Envelopment Analysis)를 이용하여 측정한다. 투입변수로서 대표적 환경요인 인 자원사용량과 오염물질배출량을 설정하고, 산출변수로서 경제적 요인인 고객효용과 기업효용을 설정한다. 사례연구로 카쉐어링 서비스 기업들의 에코효율성을 측정하고, 서비스의 특성에 따른 에코효율성의 차이를 분석한다.

This research, as a study of the documentary records, examined the process of men\`s wear development year by year, looking into the newspapers which show objectively social phenomena in those days. The outcomes therefrom were classified according to the important factors of dress and ornaments\` modeling i. e. style, color, pattern, material, ornamentation method. And then, the process of men\`s wear transition was analyzed based on the aforesaid examination with its classification. The above analyses revealed that a transition of a dress and ornaments closely correlates with a social and cultural change and also meant that the dress and ornaments symbolizes the social phenomena in those days. Thanks to the holding of Seoul Olympic Games in 1988, Korean society had tremendously grown with rapid changes in its politics, economy and culture. Also, men\`s wear type became innovative, breaking from the existing orthodox one due to the transition of men\`s viewpoints on value and their lives\` style.

We investigated the characteristics of electroless plated Cu films on screen printed Ag/Anodized Al substrate. Cu plating was attempted using neutral electroless plating processes to minimize damage of the anodized Al substrate; this method used sodium hypophosphite instead of formaldehyde as a reducing agent. The basic electroless solution consisted of $CuSO_4{\cdot}5H_2O$ as the main metal source, $NaH_2PO_2{\cdot}H_2O$ as the reducing agent, $C_6H_5Na_3O_7{\cdot}2H_2O$ and $NH_4Cl$ as the complex agents, and $NiSO_4{\cdot}6H_2O$ as the catalyser for the oxidation of the reducing agent, dissolved in deionized water. The pH of the Cu plating solutions was adjusted using $NH_4OH$. According to the variation of pH in the range of 6.5~8, the electroless plated Cu films were coated on screen printed Ag pattern/anodized Al/Al at $70^{\circ}C$. We investigated the surface morphology change of the Cu films using FE-SEM (Field Emission Scanning Electron Microscopy). The chemical composition of the Cu film was determined using XPS (X-ray Photoelectron Spectroscopy). The crystal structures of the Cu films were investigated using XRD (X-ray Diffraction). Using electroless plating at pH 7, the structures of the plated Cu-rich films were typical fcc-Cu; however, a slight Ni component was co-deposited. Finally, we found that the formation of Cu film plated selectively on PCB without any lithography is possible using a neutral electroless plating process.

Since various R&D projects about technology convergence was conducted by the government of Korea, the lack of liaisons among the projects has been accepted as serious issues related on the duplicated funding. In this article, we propose a research framework to analyze the relationship among national R&D projects about technology convergence. In detail, the projects have been sorted and categorized with the data collected from National Science and Technology Information Service (NTIS) in order to analyze the current state of national R&D projects. The linkages among projects are then established using the results of analysis on national R&D projects. Finally, the relationship maps have been developed. It is expected that the result could be applied to identify the relations among projects and handle problems on the duplicated funding.
