  • The openness of residential space directly affecting lighting, view, and ventilation leads to the variation of open floor plan type in apartment construction project. This study intends to substantiate the effect to the apartment price by design property of open floor plan based on actual design information of apartment and price. The open floor plan type and associated design property, and actual transaction price of apartment have been considered as variables for analysis by the hedonic price function model and artificial neural networks model. Research findings indicate that the openness affects the price of apartment positively and the three sides open plan is the most preferred with the highest price. This study aims to provide the implication to the developer in planning and design stage of apartment and the purchaser seeking the suitable price by floor plan design.

  • The next generation IT environment is expected to be an open computing environment based on Grid computing technologies, which allow users to access to any type of computing resources through networks. The open computing environment has benefits in aspects of resource utilization, collaboration, flexibility and cost reduction. Due to the variation in performance of open computing resources, however, resource allocation simply based on users' budget and time constraints often fails to meet the Service Level Agreement(SLA). This paper proposes the Mean-Absolute Deviation(MAD) portfolio optimization approach, in which service brokers consider the uncertainty of performance of resources, and compose resource portfolios that minimize the uncertainty. In order to investigate the effect of this approach, we simulate an open computing environment with varying uncertainty levels, users' constraints, and brokers' optimization strategies. The simulation result concludes threefolds. First, the MAD portfolio optimization improves the success ratio of delivering the required performance to users. Second, the success ratio depends on the accuracy in predicting the variability of performance. Thirdly, the measured variability can also help service brokers expand their service to cost-critical users by discounting the access cost of open computing resources.

  • High resilience PU foams were prepared with polyether type cell opener. The influences of cell opener concentration on the kinetics, rheology, structural stability morphology and open cell content of the obtained foam were investigated and the role of cell opener during cell opening was determined. And mechanical properties as a function of cell opener concentration were studied. It was observed that urea formation reaction was delayed due to high hydrophilicity of cell opener The decrease of viscosity and the increase of tan $\delta$ were confirmed with increasing cell opener concentration so that the resulted foam had low structural stability and high open cell content. The deterioration of matrix and uniform dispersion of hydrogen-bonded urea in matrix with cell opener concentration was revealed by SEM analysis. As a result, elastic properties of the foam matrix were decreased due to high hydrophilicity of cell opener during the preparation of high resilience polyurethane foam and foam with high open cell content resulted. Hardness, tensile strength, tear strength, elongation of foam were decreased with increasing cell opener concentration.

  • This paper documents the increase in earnings variability (or earnings risk) during the 1990s in Korea, and investigates whether it can be accounted for by capital market opening. The variances of transitory and permanent innovations in earnings are estimated from repeated cross-section data using a simple econometric framework. The increasing time-series pattern of earnings risk among men follows the increased foreign capital presence reasonably well, but the supporting cross-sectional evidence for a causal relationship between the two is weak. However, foreign direct investment (FDI) is found to have had some non-neutral effects on workers of varying skills in such a way that transitory earnings risk of less-skilled workers relatively increased with FDI. To the extent that transitory innovations are not fully insured, this widening effect of FDI on earnings risk gap may have contributed to widening welfare gap between skilled and unskilled workers in Korea, at least in terms of "risks."

  • Objective: The purpose of this study was to investigate the structural changes of the hyoid bone and upper airway after orthognathic surgery for skeletal class III anterior open bite patients, and make comparisons with normal occlusion. Methods: Pre- and post-operative computed tomography (CT) examinations were performed on 12 skeletal class III anterior open bite patients who were treated with mandibular setback osteotomy. Using the V-works $4.0^{TM}$ program, 3-dimensional images of the total skull, mandible, hyoid bone, and upper airway were evaluated. Results: In the Class III open bite group, the hyoid bone were all positioned anteriorly, compared to the Normal group (p < 0.05). The angle between the hyoid plane and mandibular plane in the Class III openbite group before surgery was greater than in the Normal group (p < 0.05), and the difference increased after surgery (p < 0.01). In the Class III openbite group, the volume of the upper airway decreased after surgery (p < 0.001) and the volume of the upper airway was smaller than the Normal group before and after surgery (p < 0.001). Conclusions: The narrow upper airway space in skeletal Class III openbite patients decreased after mandibular setback osteotomy. This may affect the post-surgical stability.

  • 본 연구에서는 개방구(opening)을 갖는 원자력발전소 강재 격납구조물의 내력을 평가함에 있어서 기존의 실용 구조설계에 적용된 개구부가 없는 원통형 쉘의 좌굴 판정 기준이 적절하지 않음을 밝혔으며, 대안으로서 개방구(opening)를 갖는 원통형 강재 격납구조물의 재료적 비선형과 기하학적 비선형을 고려한 극한 내력 해석을 수행함으로써 중기발생기 교체작업시 유발되는 인양 하중에 대한 격납구조물의 구조적 안전성을 평가하였다. 개방구를 갖는 격납구조물에 대하여 stiffner가 있는 상태에서 크레인 하중에 대한 극한 내력을 평가해본 결과 크레인 하중이 재하될 경우, 구조물이 선형 탄성 범위에 있는 것으로 확인되었으며 개방구 주위의 국부적인 항복응력도달 상태에 대하여 10.8의 안전율을 확보 할 수 있는 것으로 계산되었다. 본 연구를 통하여 제시된 개방구를 갖는 강재 격납구조물의 극한내력 평가 방법은 유사 구조물의 구조건전성 평가에 활용될 수 있을 것으로 사료된다.

  • SDR 시스템의 구조는 개방상, 분산성, 객체지향성, 소프트웨어 제어성을 제공하는 구조이어야 한다. 이러한 조건을 만족하는 SDR 시스템에 사용된 SDR시스템의 소프트웨어는 단일 하드웨어 플랫폼에서 독립적으로 동작이 가능한 개방성을 확보하는 것이다. 이 방법은 모듈화를 지향하며, 재사용성을 증대시키고, 개발 시에도 많은 유연성을 확보 할 수 있을 뿐만 아니라 시스템을 재구성하여 운용 할 수 있도록 해 준다. 본 논문은 SDR기반 스마트안테나 기지국 시스템에서 SDR 네트워크가 추구하는 개방형, 객체지향성 및 제어성 등을 확보 할 수 있도록 하고 SDR 네트워크와 유연하게 연동 할 수 있도록 기지국 시스템 내의 각 소프트웨어 모듈간의 인터페이스를 정의하였다. 또한, 스마트안테나 기지국의 API(Application Program Interface)를 제시하고 이에 대한 Usecase를 보임으로써 제안하는 스마트안테나 기지국의 API의 활용성을 증대시켰다.

  • This paper describes the open API with integration of semantic web service with PARLAY X based open API in 4G mobile network. It can be expected that the intelligence such as the context-awareness, adaptation and personalization in 4G mobile network will be deployed. But the existing PARLAY based network lacks in considering context-awareness, adaptation and personalization. Therefore, the object of this paper is to support the architecture and the Application Programming Interface (API) of the network service for the context-awareness, adaptation and Personalization in 4G mobile network The open API is to provide users with the adaptive network service to the changing context constraints as well as detecting the changing context and user's Preference. For instance, the open API can Provide users with QoS in network according to the detected context and user's preference, after detecting the context such as location and speed and user's preference.
