실내의 조명상황에서 Glare의 문제성을 지적하고, 실제로 공간내 조명기구로부터의 Glare를 평가하였다. 정해진 위치에서 공간을 바라봤을 때, 시야에 들어오는 광원들에 의한 직접 Glare를 각종 Glare 규정에 따라 평가를 하였으며, 상호 비교분석도 하였다. 특히, KS에서 조명기구에 대한 최대 휘도를 제한하는 G분류의 적합성을 상호 분석함으로써 그 결과를 살펴보고자 하였으며, 현 KS의 G분류의 개선점이나 보완점을 지적하고자 한다.

향후 21세기 정보사회의 구체적인 실현과 국가 경쟁력 향상의 중심적 역할을 지닌 정보통신은, 관련 기술의 통합화와 서비스의 고도화 및 다양화에 따라 정보통신 관련 제품들간의 상호운용성 확보 측면에서 표준화의 필요성이 날로 강조되어 가고 있다. 그러한 정보통신기술 발전을 위한 기반 요소로서의 표준화는 다음과 같이 두 개의 큰 맥락, ITU(국제전기통신연합)와 ISO/IEC JTC1(ISO/IEC 합동기술위원회 1)을 중심으로 국제적 표준화 추진체계를 이루고 있지만, 최근 기술의 통화화에 추세에 따라 상호 보완 및 협력을 바탕으로 공생하고 있다고 보아야 할 것이다. 여기에서는 그중 ISO/IEC JTC1의 위원회 소개와 함께 지난 1월에 열린 제13차 브라질 총회결과를 간단히 기술하고자 한다.

많은 암 환자들이 보완대체의학(CAM)의 치료법을 이용한다. 의사들은 보완대체의학 치료법에 대한 권위 있는 정보들을 이를 찾는 환자들에게 책임 있는 조언을 줄 수 있기 위해 필요로 한다. 이 글은 암 환자에게 일반적으로 사용되는 선택된 보완대체의학 치료법의 효과와 안정성에 대한 최근의 증거를 요약했다. 식이요법과 보조식품, 한약 및 기타 생약제재, 침, 마사지, 운동, 심리 및 심신의학 등의 주요 카테고리가 포함되었다. 효과의 증거에 대한 '가능한 질병진행과 생존율에 대한 효과' 및 '가능한 완화효과'의 두 가지 범주가 고려되었다. 안전성의 증거를 평가하는데 있어 '직적접인 부작용의 위험'과 '통상적 치료법과의 상호작용에 의한 위험'의 두 가지 위험 요소가 고려되었다. 각각의 치료에 있어 효용성과 안정성에 대한 현재의 균형은 이 치료법이 적절히 권고가 되고 수용되어지거나(예를 들어 유방암과 전립선암을 가진 영양 섭취가 충분한 환자의 식이지방 감소) 억제되는 것을(예를 들어 과량의 비타민 A 보조제) 제시한다. 이러한 전략은 보완대체의학의 치료법을 찾는 암환자들에게 책임 있고 근거중심적이고 환자중심적인 조언을 제공하는 것을 발전시킬 수 있다.

A joint venture approach to the marketing, organization, and execution of a project should be considered when the combined strengths of two or more entities result in a joint organization with unique credentials in a targeted business area. A joint venture is based on a complementary relationship: one party may lack one or more major elements needed for market penetration, such as technology, design-construct capabilities, geographic location, or financial strength; the other party should be able to compensate for these areas of weakness. The purpose of this study is that suggests the development direction of a joint venture, the proper organizational approach

Currently we have many DRM(Digital Rights Management) products but they do not provide interoperability between them. It causes user's inconvenience to use a DRM content and places restrictions to digital content distribution. DRM standardization to solve these sorts of problem has been discussed but dominant standardization which can provide DRM interoperability has not been made. In this paper, we propose DRM interoperable scheme by connection between heterogeneous DRM systems (EU) which uses export and import functions. Proposed EXIM can make a DRM content exchangeable between heterogeneous DRM systems with an open type of technology specification although they don't have to open their DRM structure.

This paper is to provide some suggestions to complement and extend theory of network city, and to consider preliminarily its applicability for development of the Yeongnam region, exploring its normative implications for urban and regional policy and its significance of empirical research. In order to resolve some limitations and problems of network city theory and of empirical research, we need to reconsider systematically analysis methods, to extend indices of connectivity, to reconfirm normative characters inherent in network city theory, to suggest the constitution of cooperative governance, and to develop policies for embedding functional connectivity into internal community. In a preliminary analysis of Yeongnam region on the basis of network city theory, it is not clear whether the urban system of the region is entirely a type of network city, even though it seems to be close to network city. However, in order for the Yeongnam region to orient towards network city, we can point out importance of policy issues such as expansion of transportation and communication infrastructure, strengthening of economic connectivity, constitution of cooperative governance, and local embeddedness of functional network within the region.

The effectiveness of joint operations depends on Jointness based on interoperable elements of participating forces. Many specialists have actively done research studies on interoperability measurement models with the goal of straightforward way of measuring and then have improved the interoperability of elements based on DOTMLPF-p (Doctrine, Organization, Training, Materiel, Leadership & Education, Personnel, Facilities, Policy) in the forces. After the survey of 16 interoperability measurement models, we have concluded that most of them applied only a small portion of DOTMLPF-p elements explicitly or all portions of DOTMLPF-p elements implicitly. In this study, we propose a conceptual interoperability measurement model for applying all DOTMLPF-p elements explicitly. And it can evaluate not only the level of interoperability among forces but also level of jointness for joint operations.

This study analyzed the technology innovation strategies of knowledge-based companies in the semiconductor IP industry. The theoretical approaches of this study are to i) the creation, protection and utilization of knowledge and innovation, ii) value creation from innovation, iii) modularity, timing of market entry, and the emergence and competition of standard (dominant design). Based on the theoretical analysis, I presented exploratory research hypotheses. Ultimately, this study examined the proposed hypotheses by conducting case studies on the technology innovation strategy of two leading knowledge-based companies in the semiconductor IP industry: ARM and INTEL. First, knowledge-based companies entering in the early stage of the technology cycle select the vertically-integrated technology strategy because of lower access to complementary knowledge assets, and maintain the vertically-integrated technology strategy despite the environmental change-driven differentiation of industry's value chain. Second, knowledge-based companies entering in the later stage of the technology cycle prefer the contract-based technology strategy because of its increased accessibility to complementary knowledge assets, and choose a different path of innovation strategies depending on whether their asset has the feature of discontinuity or not.

The paper is basically designed to reveal substitutability or complementary nature of export and import among Korea, China, and Japan by employing unit root test, cointegration technique, and vector error correction model(VECM). Empirical evidences are shown that the trading among these countries has been dominated by a complementary nature in the short run which enables it to promote trading in those countries. In the long run, however, the substitutability nature effects strongly to the trading among Korea, China, and Japan. To this end, it could be tentatively concluded that market-oriented trading policies are more effective to stimulate the export and import in those countries in the short run, while a trading policy has to be selectively implemented by the substitutability nature in the long run basis. For instance, a stability policy for exchange rates and various commercial policies could be set for a short term target. Whereas, the substitutability nature should be counted in building up a new industrial structure or in implementing FTA agreement among Korea, China, and Japan.

본 논문에서는 보편적으로 태양광 시스템에 적용되는 MPPT(Maximum Power Point Tracking) 기술들이 가지는 단점을 상호 보완하는 하이브리드 MPPT 제어 알고리즘을 제안하였다. 널리 사용되고 있는 MPPT 기술들을 비교하여 분석하였고, 이를 바탕으로 각 기술들의 단점을 상호 보완할 수 있는 요소들을 추출하여 MPPT 알고리즘에 적용하였다. 구현된 알고리즘은 최대전력점으로부터 동작점이 떨어져 있는 경우 빠르게 추적할 수 있는 속응성을 가지며, 정상상태에서는 안정도를 높이고, 국부적인 최대전력점(LMPP; Local Maximum Power Point) 발생 시 이를 감지하여 전체 특성 곡선의 최대전력점(GMPP; Global Maximum Power Point)을 찾아가도록 하였다. 또한 시뮬레이션을 통해 그 특성을 확인하였다.
