본 연구는 국내 복합상업시설의 진화과정을 핵심사례를 중심으로 살피고, 그 외부공간의 기능적 구성방식과 주변경관 및 오픈 스페이스, 나아가 지역사회와의 관련성을 살펴봄으로써, 복합상업시설 외부공간의 조성경향의 변화를 파악하고, 도시 속 공공적 성격의 오픈스페이스로서의 가치를 재고하고자 한다. 본고는 국내 복합상업시설의 외부공간이 상업시설 건물군과 주변경관과 맺는 상관관계를 기준으로 분류하여 내외부공간 단절형, 내외부공간 반개방형, 주변경관 투영형, 주변경관 결합형으로 구분하여 설명하였다. 각 유형의 대표적 사례들을 통해 외부공간의 기능적 구성과 조경 특성을 고찰하여 다음과 같은 결론을 도출할 수 있었다. 첫째, 외부공간이 상업건물에 종속된 역할을 주로 담당하던 것에서 나아가 각종 활동과 경험을 위한 적극적 참여형 공간으로 활용되는 외부공간의 활성화 경향을 읽을 수 있었다. 둘째, 내·외부공간의 연계방식이 활성화되어, 실내 쾌적성을 증진시키는 외부환경요소를 적극 실내로 도입하고, 내부의 특정 프로그램공간을 외부환경과 직접적으로 연결함으로써 내·외부환경이 융합된 풍부한 공간 경험을 제공하는 추세이다. 셋째, 외부공간의 기능 확대와 복합상업시설의 여가공간화로 인해 상업공간의 공공성이 증가되어 복합상업시설의 역공간적 기능이 확대되는 경향을 볼 수 있었다. 주변녹지와 연계된 교외형의 사례에서는 외부공간의 동선 기능과 조경제안을 분석하여 외부공간이 내부가로 및 도시가로와 유기적으로 연결된 주동선의 기능을 담당하고, 상업공간 조경이 공공 오픈스페이스 체계와 결합된 지역문화·녹지체계의 중심지가 되는데 기여할 가능성을 실례를 통해 살펴보았다.

With the intensification of urban development in Chinese cities, mixed land use in urban centers extends vertically into 3-D and expands its scale from a single building to commercial clusters. The multi-level pedestrian system in city centers also changed its role from one of traffic isolation to spatial integration, where transit nodes, street sidewalks, squares, building entrances, atriums, and corridors are interconnected, both horizontally and vertically, into a whole spatial system, within which pedestrian flows are guided and shopping facilities are arranged. This paper uses spatial configuration analysis of space syntax to examine the impacts of spatial patterns on movement distribution and the business performance of tenant mix in the multi-level commercial system of the Nanshan Commercial Cultural District in Shenzhen, China. The key objective is to better understand the interactions between the socio-economic variables and spatial design parameters of a shopping complex. The research findings point to the importance of multiplicity between syntactic variables and other spatial variables in influencing the pedestrian flows, business performance and tenant mix in highly complex commercial systems. Particularly noteworthy is the relationship between spatial accessibility measures and the location of escalators, and the ways in which individual commercial buildings are embedded into the overall spatial system. The study suggests that this may lead to the preliminary identification of the spatial qualities of effective vertical extensions of mixed land use in a high-density urban settings.

In this paper, we implement a navigation software of a Global Navigation Satellite System (GNSS) receiver based on a commercial purpose GNSS software receiver platform and verify its performance by performing experimental tests for various GNSS signals available in Korea region. The SX3, employed in this paper, is composed of an application program and a Radio Frequency (RF) frontend, and can capture and process multi-constellation and multi-frequency GNSS signals. All the signal processing procedure of SX3 is accessible by the receiver software designer. In particular for an easy research and development, the Application Programing Interface (API) of the SX3 has a flexible architecture to upgrade or change the existing software program, equipped with a real-time monitoring function to monitor all the API executions. Users can easily apply and experiment with the developed algorithms using a form of Dynamic Link Library (DLL) files. Thus, by utilizing this flexible architecture, the cost and effort to develop a GNSS receiver can be greatly reduced.

This study investigated commercial power theory of traditional market through the analysis of literature review. Consumers' store selection models are made up a theory based on normative hypothesis, theory of mutual reaction, utility function estimation model, and cognitive-behavioral model. Detailed models are as follows. Normative hypothesis based theory is divided into Reilly's retail gratification theory and Converse's revised retail g ratification theory. Interaction theory is composed of Huff's probability gratification theory, MCI model and Multi-nominal Logit Model (MNL model). There are four models in retail organization position theory such as central place theories, single store position theory, multi store position - assign model, and retail growth potential model. In case of single store position theory, theoretical and empirical techniques have developed for a decision to optimum single store position. Those are like these, a check list, the most simple and systematic method, analogy, and microanalysis technique. Aforementioned models are theoretical and mathematical commercial power measurement and/or model. The study has rather limitations because the variation factors included in formula are only a part of actual commercial power. Therefore, further study shall be made continuously to commercial power areas and variables.

This paper presents a multi-phase ring VCO for low-cost, low-power GPS receiver. In the RF band used in GPS, L1 band is now in commercial-use and L2,L5 are predicting to be commercial-use soon. Thus Wide band PLL and Cost-effective IC solutions are required for future multi-band GPS receiver that received three types band at once. A new PLL architecture for multi-band GPS application is proposed. Ring VCO is even smaller than LC-VCO and a good alternative for low-cost solution. Proposed multi-phase ring VCO offers wide frequency range covering L1, L2, and L5 band, 20% reduction of area, 23% reduction of PLL power and can generate I/Q without extra I/Q generator.

Unpreparedness of the maintenance regulations is regarded as the main reason for the short life span of the multi-owned commercial residential buildings. This study suggests that the followings should be prepared for the effective maintenance and life prolongation of the multi-owned commercial residential buildings : 1) Standard maintenance regulations for those buildings should be set up, 2) Building maintenance works should be performed by the specialists, like licensed building manager, mechanical and electrical engineers, etc., 3) Long-range repair expenses should be laid by on the monthly base according to the long-range repair plan, 4) Regulations concerning the defect repair should be provided properly.

Time domain response analysis for vibro-impact nonlinear behavior of multi-span tube with loose supports was performed using commercial FEA code and user subroutine. Support geometry of multi-span tube with a finite gap is realistically modeled by analytical rigid surface. Model of hydrodynamic force is based on the Qusai-steady model which accounts for the inclined angle of relative flow velocity and time delay between flow force and resulting tube motion. During tube vibration from flow loading, impact and friction at the support location is simulated using commercial FEA code with master slave contact algorithm. Analysis results has reasonable agreement with those of references and test experience. Plan of further refinement of analysis model and future test verification is briefly introduced.

Multi-leaf springs are widely used for a major suspension component in many commercial vehicles. The modeling technique of multi-leaf springs is one of the most difficult problems in suspension modeling as the elements have complicated nonlinear characteristics such as a hysteresis behavior due to the friction. In this paper, hysteretic characteristics with the static and dynamic test are modeled and are simulated with three links and joints in MSC.ADAMS. Simulation results showed good agreements with test results. Using this methodology, it is expected that dynamic characteristics of suspension system with multi-leaf spring can be more accurately evaluated in vehicle dynamics.

복수의 국가 및 당사자간에 계약 방식이 복잡하고 다양화되면서 양당사자뿐만 아니라 수인의 당사자들이 중재에 참여하기 때문에 국제상사분쟁에서 다수당사자중재의 필요성이 제기되었다. 다행히 당사자의 합의에 기초한 중재가 국제분쟁해결수단으로서 활용되고 있으므로, 다수당사자 분쟁에서 다수당사자간의 합의를 기반으로 한 중재절차의 병합의 중요성이 높아지고 있다. ICC의 중재규칙 뿐만 아니라 우리나라 대한상사중재원의 국제중재규칙의 개정과 함께, 국제상사중재에서 다수당사자분쟁을 신속하고 효율적으로 해결하기 위한 방안인 중재병합의 적용과 그 집행상의 쟁점을 고찰해 보고자 한다.
