Since 2010, issues for data sharing and data exchanging in hospital information systems have been emerged. In order to solve the issues, standards should be applied to develop the systems and there should be no ambiguities between terminologies in the systems. In this paper, the terminology mapping system for narrative clinical records was implemented. The term mapping precision was 83.4%. This system could help to upgrade the text based clinical system and it would be expected to support for high quality clinical services.

GUI(Graphic User Interface) have an influence on end-user environments in information system. Consistency is one of the most important GUI characteristics. Consistency should apply across the different media which form the total user interface. User can get a lot of benefits through consistency. To achieve consistency of the total interface, the interface standards are very important. The goals of this study is to suggest GUI's development guidelines through analysis of real fields using ERP package in a electric assembly line. The guidelines fall into four functions: inquiry, registration, modification, deletion. The guidelines can be used for better system development later and as verification tool in GUI development.

The electronic structure at organic-organic interface gives essential information on device performance such as charge transport and mobility. Especially, the molecular orientation of organic material can affect the electronic structure at interface and ultimately the device performance in organic photovoltaics. The molecular orientation is examined by the change in ionization potential (IP) for metal phthalocyanines (MPc, M=Zn, Cu)/fullerene ($C_{60}$) interfaces on ITO by adding the CuI templating layer through ultraviolet photoelectron spectroscopy measurement. On CuPc/$C_{60}$ bilayer, the addition of CuI templating layer represents the noticeable change in IP, while it hardly affects the electronic structure of ZnPc/$C_{60}$ bilayer. The CuPc molecules on CuI represent relatively lying down orientation with intermolecular ${\pi}-{\pi}$ overlap being aligned in vertical direction. Consequently, in organic photovoltaics consisting of CuPc and $C_{60}$ as donor and acceptor, respectively, the carrier transport along the direction is enhanced by the insertion of CuI templaing layer. In addition, optical absorption in CuPc molecules is increased due to aligned transition matrix elements. Overall the lying down orientation of CuPc on CuI will improve photovoltaic efficiency.

We analyzed the interface characteristics of Zn-based thin-film buffer layers formed by a sulfur thermal cracker on a $Cu(In,Ga)Se_2$ (CIGS) light-absorber layer. The analyzed Zn-based thin-film buffer layers are processed by a proposed method comprising two processes - Zn-sputtering and cracker-sulfurization. The processed buffer layers are then suitable to be used in the fabrication of highly efficient CIGS solar cells. Among the various Zn-based film thicknesses, an 8 nm-thick Zn-based film shows the highest power conversion efficiency for a solar cell. The band alignment of the buffer/CIGS was investigated by measuring the band-gap energies and valence band levels across the depth direction. The conduction band difference between the near surface and interface in the buffer layer enables an efficient electron transport across the junction. We found the origin of the energy band structure by observing the chemical states. The fabricated buffer/CIGS layers have a structurally and chemically distinct interface with little elemental inter-diffusion.

In this work, we developed self-assembled monolayers (SAMs) of alkanethiols on gold that can release amine groups, when an electrical potential was applied to the gold. The strategy was based on the introduction of the electroactive carbamate group, which underwent the two-electron oxidation with simultaneous release of the amine molecules, to alkanethiols. The synthesis of the designed thiol compounds was achieved by coupling isocyanate-containing compound with hydroquinone. The electroactive thiols were mixed with hydroxyl-containing alkanethiol [$HS(CH_2)_{11}OH$] to form mixed monolayers, and cyclic votammetry was used for the characterization of the release. The mixed SAMs showed a first oxidation peak at +540 mV (versus Ag/AgCl reference electrode), demonstrating irreversible conversion from carbamate to hydroqinone with simultaneous release of the amine groups. The second and third cycles showed typical reversible redox reaction of hydroquinone and quione: the oxidation and reduction occurred at +290 mV and -110 mV, respectively. The measurement of ToF-SIMS further indicates that electrochemical-assisted chemical reaction successfully released amine groups. This new SAM-based electrochemistry would be applicable for direct release of biologically active molecules that contain amine groups.

The paradigm that ships are navigated by means of analog navigation devices and caption's experiences is shifted to that ships can be navigated by digital and autonomous navigation systems due to the rapid development of electronics and communication technologies. Hence, all systems deployed in a ship are automated and integrated since corresponding ship systems are not individually operated but integrated and managed under common operating system. In this paper, we overview recent research projects targeted for digitally integrated ships (referred to as digital ships), outline IEC 61162 series, specifying digital interface standards for digital ships, and finally present several issues for further improvement of the IEC 61162 series. In addition, we broadly categorize digital ships into three systems consisting of multiple sub-systems, including a navigation system, a power system, and a automation system in the aspect of operation and function. Corresponding interfacing range and method, as well as interface specification and data types of one system in a digital ship are also described according to sub-systems, respectively.

향상된 사용자 상호작용 (AUI: Advanced User Interaction) 인터페이스(interface)의 목적은 다양한 입/출력 장치와 비디오, 오디오, 그래픽 등의 객체로 표현되는 장면 기술(scene description) 사이에서 정보의 상호연동을 향상시키는 것이다. 이를 위해서 국제 표준화 기구인 MPEG(moving picture experts group)에서는 MPEG-U part 2: AUI Interface 프로젝트를 통해서 AUI 인터페이스 데이터 포맷의 표준화를 진행 중이다. 본 논문에서는 MPEG-U part 2의 표준을 소개하고, 이 표준에 기반을 둔 AUI 인터페이스 시스템을 제안한다. 제안하는 AUI 인터페이스 시스템은 크게 UID(User Interaction Device)의 데이터를 처리하는 사용자 인터페이스 입/출력부와 XML 문서를 처리하는 MPEG-U XML 생성/해석부로 구성된다. 본 시스템은 MPEG-U 표준 기반 입/출력 장치와 사용자와의 상호작용을 향상시키기 위한 시스템의 프레임 워크로 활용될 수 있다. 실험에서는 제안하는 사용자 상호작용 인터페이스 시스템이 MPEG-U part2 표준에 적합한지를 보이며 이를 이용하여 MPEG-U part 2 표준의 타당성을 검증한다.

대학 web도서관은 web으로 도서관에 소장된 서지나 기타 자료의 검색, 대출, 반납에 관한 정보의 처리가 가능하도록 되어 있는 도서관의 형태이다. 정보화 사회에 진입 한 이후 네트워크와 멀티미디어란 것의 등장으로 인해 정보전달 및 획득의 수단과 과정에 있어서 엄청난 변화를 겪고 있다. 이미지 화, 동영상 화 된 방대한 멀티미디어 정보들이 네트 워크를 통해 정보 제공자와 정보 사용자간의 물리적 거리에 대한 한계를 느끼지 못하게 되었다. 하지만, 이에 따르는 문제점으로는 저작잔 인식부족, 인프라의 미비, 기술적, 신뢰성 등으로 인해 발전이 요구되는 상태이다. 본 논문에서는 국정 대학 평가 기준에 근거하여 20개 대학의 web기반 도서관 site에서, 각 시스템별 검색 형식과 user interface를 비교, 분석하였다. 이에 기초하여 web기반 대학 도서관의 실험적 user interface를 제작하고, 이 interface에 대한 설문조사 및 데이터를 수집, 정리, 분석하였다. 이 결과를 현재web기반 대학도서관의 일반검색 시스템의 인터페이스에 적용하여 도서의 위치, 도서의 대출 및 검색회수, 대학 web도서관 내에서의 도서구입에 대한 기능을 포함하는 새로운 user interface를 제안하였다.
