The high-technological in the electric and electronic industries is recognized in overseas markets as well. However, the competition for technologies in these industries is increasing. Therefore, electric and electronic firms should be more efficient in their production. so, This paper analyzes the efficiency of High-growth Electrical and Electronics firms using DEA model. We evaluate the CCR, BBC efficiency and RTS(return to scale) of 20 Korean high-growth Electrical and Electronics firms. There are a total of 12 efficient DMUs with a BCC of 1. There are a total of 4 efficient DMUs with a CCR of 1. A total of 11 DMUs were IRS in Scale Efficiency and a total of 6 DMUs were CRS in Scale Efficiency and a total of 3 DMUs were DRS in Scale Efficiency. We also suggest the Electrical and Electronics firms which can be benchmarked based on analyzed information.

Data-adaptive sequential suboptimal designs for very complex computer simulation codes are considered based on a spatial prediction model. These designs are constructed for two simulators of the computational nuclear fusion devices model. The difficulty of constructing the optimal designs due to the irregular design region, and its alternatives are also discussed with some computational algorithms for obtaining the designs.

표면영상유속계(SIV, Surface Image Velcimetry)는 수표면의 영상분석을 통해 유속을 측정하는 도구이다. SIV는 하천의 유속을 매우 간편하게 측정할 수 있기 때문에, 야외 실험이나 하천의 유속 측정에 매우 유용한 장비이다. 그러나, SIV를 이용하여 유량을 산정하고자 할 경우, 하천 표면의 평면 측량 자료와 하천의 단면 측량 자료가 반드시 필요하다. 그러나, 측량 작업 특히 강우 중의 측량 작업은 매우 번거롭기 때문에, SIV의 간편성과 유용성에도 불구하고, 이용자들로 하여금 SIV를 쉽게 이용하기 어렵다는 그릇된 인식을 줄 수 있다. 만일 번거로운 측량을 거치지 않고도 효율적이고 간편하게 하천의 평면을 추정할 수 있다면, SIV를 마치 일반적인 프로펠러 유속계처럼 쉽게 이용할 수 있을 것이며, 그 적용성도 크게 증진될 것이다. 본 연구는 카메라 영상 모형을 유도하는 것이다. 이 카메라 모형을 이용하여 번거로운 측량 작업이 없이 평면의 좌표점을 추정할 수 있게 되며, 유속장 측정을 자동화할 수 있을 것이다. 이를 위하여 평면 좌표와 참조점을 관련짓는 사영 변환과 회전 변환 등 사진 측정 기법을 도입하였다.

제방의 붕괴는 전체 수공구조물 중 70%를 차지하고 있으며, 그 중 월류에 의한 피해가 40%로 가장 많은 비율을 차지하고 있다. 제방을 월류하여 제내지로 유입되는 붕괴유량은 높은 속도로 제내지로 전파된다. 제방붕괴로 인한 피해를 줄이기 위해서는 이러한 붕괴파의 거동에 대한 연구가 필요하다. 기존의 연구들에서는 제방의 붕괴를 수문의 개방으로 가정하여 제내지 유입을 재현하였다. 본 연구에서는 제방의 규격은 높이 3 m, 정부폭 3 m, 사면경사가 1:2인 제방에 대해서 1/10 축척으로 수리모형실험을 실시하였으며 제방의 붕괴부를 모래를 축조하여 이동상으로 제작하였고 이동상 제방의 길이는 4 m이다. 제방에 월류를 유도하여 붕괴를 유발하였으며 홍수파가 제내지로 유입되는 속도 및 경향을 기록하였다. 제내지는 길이 6 m, 폭 6 m로 수평하게 제작하였다(그림 1 참조). Froude 수 변화에 따라 제내지로 유입되는 범람홍수파의 전파 경향을 분석하였으며 그 결과 Froude 수가 클수록 선단 홍수파의 방향이 하류방향으로 전파되는 경향을 나타냈다.

This study intends to design the bibliographic framework based on IFLA-FRBR model for television program materials and to evaluate this in terms of effectiveness of retrieval and usability of the system. The FRBR model supplies mote suitable bibliographic framework of audio-visual material which has a sufficient hierarchical relations and relative bibliographical records. The followings are research methods designed by this study; (1) The experimental metadata system named it FbCS based on FRBR was developed by using the entity-related database and composed of multi-layed and hierarchy. FbCS is developed through benchmarking of a case study for iMMix model in Netherlands based on FRBR. (2) To evaluate effectiveness of retrieval and usability of FbCS, this study made a experiment and survey by user groups of professionals.

For long-term preservation of electronic records, the information on the whole processes of management from the time of creation of the electronic information should be captured and managed together. Such information is supported by preservation metadata thus the implementation of preservation metadata is important for preservation of electronic records maintaining the record-ness. Preservation metadata is the information that supports the process of digital preservation and functions th maintain long-term viability, renderability, understandability, authenticity and identity of digital resources. Preservation metadata should be developed applying the international standard Reference Model for an Open Archival Information System(OAIS) to have international interoperability for exchange and reuse. Initial international preservation metadata schemas were developed standardizing the OAIS Reference Model. But the preservation metadata schema of Victorian Electronic Records Strategy(VERS) and recently published Data Dictionary of PREMIS Working Group were developed in advanced types that are different from the existing framework. Those were advanced th practical ones from conceptual one. Comparing these two cases, proposed the elements of integral preservation metadata for long-term preservation of electronic records. This thesis has the significance that it has suggested the direction for future development of the elements of preservation metadata by setting the past discussions related to preservation metadata in order and proposing integral preservation metadata elements for long-term preservation of electronic records.

Due to the acceleration of medical information age, the semantic interoperability of clinical information is rising up as a major issue. The laboratory results are known as the best significant area among clinical information to be required for exchanging and sharing. The aim of this research is to develop the clinical contents model for exchange laboratory results. This research was conducted from March 2008 to September 2008. Firstly, the method is to get the attributes and codes from LOINC which is one of the standard medical terminology system related to laboratory and the Reference Information Model(RIM) of Health Level 7(HL7). Secondly, the attributes from each work process around orders and reports of laboratory was analyzed. We evaluated the attributes whether they could be represented into the attributes contained in HL7's RIM. Thirdly, the prototype for hemoglobin case using the structure of clinical contents model and defined attribute. Fourthly, the face validity was done by one laboratory physician with four clinicians. The assessment contents were for the suitability involved in representation and exchange with proposed model. The results shows that the model corresponds with the aim of the research. Eventually the proposed model for the exchange of laboratory results could contributes to information interchange according to laboratory area for the future.

The biological resources research data around the world are not only very critical themselves but should be shared and utilized. Up to now, the biological resources have been compiled and managed individually depending on the purpose and characteristics of the study without any clear standard. So, in this study, the data reference model would be suggested which is applicable in the phase ranging from the start of the construction of the information system and which can be commonly used. For this purpose, the data model of the related information system would be expanded based on the domestic and foreign standards and data control policy so that the data reference model which can be commonly applicable to individual information system would be developed and its application procedure would be suggested. In addition, for the purpose of proving the excellence of the suggested data reference model, the quality level would be verified by applying the Korgstie's data model evaluation model and its level of data sharing with the domestic and foreign standards would be compared. The test results of this model showed that this model is better than the conventional data model in classifying the data into 4 levels of resources, target, activities and performances and that it has higher quality and sharing level of data in the data reference model which defines the derivation and relation of entity.

The purpose of this study is to develop a collaborative model for the archiving and preservation of an electronic book(e-book). In this study the way of the archiving and preservation for the e-book to deal with the technology evolution was suggested. Accordingly, the survey was made for obtaining the present status of the production and distribution of the domestic Online e-book. It is the same as the operation status of the archiving and preservation for the Online e-book worldwide. A collaborative model for accessible to preserved data, regardless of time period, was proposed for archiving the e-book, based on the OAIS reference model. There are three different models, suggested for domestic; the safe place model by law, the individual preservation/Peer-to-Peer model, and the preservation center model for e-book archiving. Among them, the safe place model by law was proposed for the optimum model of archiving an e-book at present.
