Cognitive-communicative disorders after traumatic brain injury(TBI) and right hemisphere damage(RHD) are different from other neurological disorders in nature. Therefore, it is not desirable to use aphasia tests in evaluating individuals with TBI or RHD. The aim of this study is to review assessment protocols on TBI and RHD, and literature related with them. As a result, it is recommended that individuals with TBI be examined in scope of the cognition including attention, memory, organization, reasoning, as well as the functional communication. Similarly, it is useful to consider high-order language related to various cognitive domains in assessing cognitive-communicative ability after RHD. In conclusion, we need to focus on the overall cognitive-communicative domains in an evaluative process of TBI and RHD. Furthermore, it is necessary to develop multiple items for individuals with cognitivecommunicative disorders for the purpose of differentiating these heterogeneous groups from other neurological disorders such as aphasia, and of making good use of them as a therapeutic manual.

With UHD broadcasting commercialization accelerating, It is urgent that government has to support a necessary policy and a flexible development of culture content to effectively spread UHD TV. On May 5, 2010, Korea Communications Commission already promised to introduce UHD broadcasting system to invigorate a local broadcasting and communication market while KCC announced top-ten future services of broadcasting and communication. To its disappointment, the market has not got a great result yet. Above all, government, companies and consumers have to exchange and meditate opinions constantly to find desirable solutions. This study aims at searching for more effective and versatile application to expand UHD TV and evaluate consumer's feedback. Based on the objective data on the current situation of the world wide UHD TV distribution and specific methods for solving challengeable issues, the research will find out more active approach to inducing government support and motivating content makers. Hopefully, the study result will make a helpful suggestion for government, company and UHD content makers.

The objective of establishing IETM (Interactive Electronic Technical Manual) is not the just making into on-1 me system of technical manuals such as specifications. It is to produce construction standard documents in an electronic manual system to turn technical contents such as construction methods in technical manuals into multimedia information. Also, it is to maximize real-time information delivery by using visual data of construction sites. IETM enables to check not only design standards in the design but also applied situation of a construction method based on proper design standards and historical construction data on a real time basis. This study suggests a modeling method of IETM applicable to design and construction phase. The study includes a framework and a scenario for developing design IETM for construction project.

Metadata Registry was developed to dynamically manage metadata and to increase interoperability between various and heterogeneous metadata. The built metadata registry can be used as a standard guideline for creation of new databases and it provides a radical data integration mechanism. However, in the situation that an enormous databases must be integrated progressively, there is a limit to the existing metadata-based approach. In case that each database has no statistical information for its use rate and the restricted cost is given to us for a unit time, existing metadata-based approaches do not provide how to select some databases to be preferentially integrated and to build a metadata registry progressively, In this paper, we propose a methodology that can create progressively metadata registries in the case. The proposed methodology is based on data visibility and hierarchical metadata registry. We also describe the system that have been developed for applying the methodology to a real domain, and then described its results.

최근 기후변화 위기에 따른 대책으로 하천 유량 모니터링이 제시될 정도로 유량자료의 중요성이 확대되고 있다. 하천의 유량자료는 수자원개발 및 하천 방재의 중요한 기초자료로 이용되기 때문에 유량 산정 결과에 대한 신뢰도 즉, 측정 불확도를 정량적으로 제시하기 위한 연구는 오래 전부터 많은 연구자들에 의해 수행되었다. 1963 ~ 1970년에 영국 및 미국의 다수 하천의 유량 측정자료를 활용하여 국제표준화기구(ISO)에서 제시한 ISO 748이 대표적인 지침서이다. 현재 국내 유량조사 업무에서도 ISO 748의 측정 불확도 평가 방식을 이용하여 유량 측정 결과의 신뢰도를 제시하고 있다. 하지만 하천 유량조사는 현장 상황과 측정 인력의 경험 등에 따라 차이가 크게 발생할 수 있으며, 최근 첨단 센서를 활용한 유량 측정 기법들이 다수 개발되어 사용 중일 뿐만 아니라 측정 불확도 평가 체계를 GUM(Guide to the Expression of Uncertainty in Measurement)으로 변화해가고 있는 추세 등을 고려하였을 때 기존의 ISO 748에서 제시한 유량 측정 불확도 평가 방법에 대한 재검토에 대한 요구가 증대되고 있다. 특히 국내에서 홍수 시 유량 조사 방법으로 가장 많이 사용하고 있는 부자법의 경우 ISO 748에서 제안한 방법으로 측정 불확도를 제시하고 있지만 실제적으로 현장 상황을 고려하지 못하고 있는 것이 사실이다. 예를 들어 육안으로 관측하기 어려워 부자의 유하거리를 직선으로 가정함에 따른 불확도를 포함하지 못하고 있고, 부자가 유하하는 동안 부자의 흘수가 일정하지 않음에 따른 불확도를 포함하지 못하고 있다. 특히 부자 투하 측선과 유량 측정 단면을 부자가 지나가는 측선이 다름에 따른 불확도는 반드시 포함되어야 하지만 고려할 방법이 없어 아직까지 반영되지 못하고 있는 실정이다. 이에 본 연구에서는 부자를 이용한 유속 측정 불확도 산정에 있어서 그동안 ISO 748에서 정량적으로 고려하지 못한 불확도 인자들에 대하여 영상기법을 활용한 실험적 검토를 통해 정량적인 평가 기준을 제시하고자 한다. 이를 위해 실제 하천 규모의 흐름을 재현할 수 있는 안동하천실험센터의 직선수로에서 다양한 수리조건에 대한 부자를 이용한 유속 측정을 실시하여 측정 불확도를 산정하고자 한다. 본 연구 결과는 향후 부자를 이용한 유량 측정 불확도 평가 방법을 개선할 수 있고, 더 나아가 부자를 이용한 유량 측정 방법의 문제점을 개선할 수 있기 때문에 정확도를 향상에 크게 기여할 수 있을 것으로 기대한다.

정부는 1998년부터 4대강 물관리종합대책을 세워 하천의 수질보전을 위한 대책을 시행하고 있다. 그 중 대유역 중심의 수질개선대책은 전체적인 큰 목표를 제시하는 것이며, 이러한 대유역의 목표수질을 달성하기 위해서는 먼저 소유역의 수질개선이 이루어져야 한다. 현재 영산강유역에서는 도시하수종말처리장, 산업폐수처리장과 같은 점오염원 관리시설은 대폭 확충되었으나 하천과 호소의 수질은 크게 향상되지 못하고 있다. 이는 중 소유역에 대한 효율적인 수질개선대책이 없기 때문이며, 특히 중 소유역 내 비점오염원 물질이 대량으로 하천 및 호소에 유입되기 때문이다 따라서 효율적인 유역관리를 위해서는 소유역중심의 관리가 필요하며, 소유역 중심의 수질보전 대책을 수립하기 위해서는 대상 소유역에 대한 조사분석이 선행되어야 하는데, 여기에는 관거(우수관, 오수관) 시스템 조사와 하수의 차집조사가 관계되며, 또한 소유역내의 오염원(점오염원과 비점오염원) 및 잠재적인 오염원조사 등과 같은 광범위한 조사 작업이 필요하다. 한편 유역모형 중 HSPF모형은 모형의 적용에 필요한 방대한 자료와 노력을 최소화 되도록 개발되어 왔으며, HSPF는 광범위한 수문 수질과정을 장기 모의가 가능하도록 일련의 구조화된 모듈로 구성되어 있다. 복잡한 모형일수록 자료관리에 많은 노력이 요구되나 HSPF는 자료를 직접적으로 접근할 수 있는 Time Series Management System에 가깝도록 개발되었다. 또한, HSPF 모델은 유역내의 토지이용에 따른 특정 오염물질의 비점오염 부하를 계산하며, 강우에 따른 물의 흐름을 하천의 수질오염모의와 연결시키는데, 광범위한 유역조건에 적용이 가능하고, 각 소유역을 구분하여 비교가 가능하므로 소유역별 관리방안을 비교하는데 가장 적합한 모델이다. 따라서 본 연구는 유역모형(HSPF)을 이용하여 영산강 유역을 대표할 수 있는 중 소유역을 선정하고, 선정된 중 소유역에 대한 기초적인 자료를 조사 분석하여 종합적이고 구체적인 유역 관리계획을 수립해 봄으로써 중 소유역 수질관리에 지침서로서 역할을 하는데 목적이 있다.

In this paper, soil erosion and soil loss management system (SMS) of the City of Calgary in Albert, Canada was reviewed. Regulatory basis supporting this soil management system, permit process and conditions, guidelines and principles for the SMS, and monitoring and repair duties, inspection were discussed. Permit process in the City of Calgary is handled mainly by Urban Development Division, in which special task force called CPAG (Coorporative Planning Application Group) (if necessary circulated through related subdivisions). Inspects all the permit conditions and decides permit or refusal, and LUM (Land Use and Mobility) advertises the approval, if there is no appeals, permit is released to developers. If permit is rejected, applicant can appeals Development Appeal Board, it can approve or reject. In addition to permit, the city has manual for soil management plan, which includes BMP selection, design, monitoring, maintenance, and inspection activities. Perfect SMS policy does not necessarily guarantee relieving the soil-particle related pollution problem, but in Korea, we have to recognize that construction works during development is potentially the most destructive stage of environmental pollution. The central and local governments must make preparations for the effective and tight regulations and ordinance which is appropriate for regional social-economic conditions.

As homenetwork has been built at general homes, users want to connect various types of devices and control them. To realize a new environment that most people dream, there have been many services developed, and the various types of devices have been proposed and then their usage and validity have been reviewed. However, as the technical design guideline seems to be prepared soon for the standardization under the situation that has been progressed mainly by technology-lead style so far, making homenetwork a product is expected to be advanced, and therefore now it is the time to discuss the design development at full stage, which is really valuable for users. We have to consider it not to make any alienated class in the society on the whole when considering these devices, and also we have to develop the design by differentiating it toward the direction that we accept users and use environment's special conditions. In addition, each devices should have reliability, no malfunction or error and long life span. At the same time, those products, which can be new changes we can joyfully accept as well as the habits we are already accustomed to, should be developed, and thereby they may naturally have to be absorbed into our present living. The design development direction for future homenetwork can vary depending on our expectation and needs, and it will become a good guidebook for the producer who have to invest much financially or in time. Therefore, this study intends to examine the present network trend and development direction and then suggest the product design direction for future homenetwork.

This research focuses on what factors determine firm's decisions on R&D outsourcing and how R&D outsourcing affect R&D performance. In recent years many firms outsource R&D activities instead of internalizing it. Thus, further investigation is necessary to find out this recent trend. Based on several theoretical background the study developed three determining factors of R&D outsourcing which are transactional level, firm level, and risk level. Transactional level composes of independent variables such as R&D cost saving, asset specificity and uncertainty which mainly comes from Transaction Cost Economics theory. Firm level composes of openness to technology from outer source, R&D capability, and outsourcing experience. Risk level composes of technological risk, cost-related risk and managerial risk. The result shows that R&D outsourcing is significantly related to cost saving aspect, low asset specific firms, firms without solid technological background, firms which are open to external technology, firms with other types of outsourcing experience, and firms which take technological risks. However, proposed relationship between degree of R&D outsourcing and R&D performance found out to be insignificant. This research is contribute to the field of outsourcing study since it will give guidance to managers who need to make strategic decisions on R&D outsourcing activities.
