나카가미 페이딩 환경하에서 MRC 다이버시티와 간섭제거기를 채용한 DS/CDMA 통신 시스템의 성능 분석
소준영,강희조 한국전자파학회 1999 한국전자파학회논문지 Vol.10 No.7
본 논문에서는 무선 채널 환경에서 다중접속간섭(MUI: Multi-User Interference)과 나카가미 페이딩에 의한 DS/CDMA GMSK 시스템의 성능을 분석하였다. 고려되는 DS/CDMA GMSK 시스템은 시스템의 성능을 향상시키기 위하여 최대비 합성(MRC) 다이버시티 수선법과 간섭제거기를 사용하였다. 유도한 오율식을 이용하여 DS/CDMA GMSK 시스댐의 성능을 구하여, PN 코드 길이(N), 다중 사용자의 수(K), 다이버시티 가지의 수(L), 비트에너지 대 잡음전력비($E_b/N_0$), 페이딩 지수(m)등을 함수로 하여 그래프로 나타내고 분석 하였다. 분석결과에 의하면 MRC 다이버시티 기법이나 간섭제거 기법을 채용함으로써 큰 폭의 성능 개선을 얻을 수 았었다 또한 MRC 다이버시티와 간섭제거기를 직렬로 채용하면 더 큰 개선을 얻을 수 있었다. 결과적으 로 제안된 시스템 구조는 나카가미 페이딩. 다중접속간섭, 다중경로 채널에서 음성 통신시스댐으로서 적절하 다고 예상된다. In this paper, error performance of DS/CDMA GMSK system has been analyzed in a radio channel which is characterized by multi-user interference(MUI) and Nakagami fading. The DS/CDMA GMSK system adopts Maximum Ratio Combining(MRC) diversity and co-channel interference (CCI) to enhance system performance. Using the derived error probability equation, the error performance of DS/CDMA GMSK system has been evaluated and shown in figures to discuss as a function of PN code length(N), number of multi-user(K), number of diversity branch(L), and bit energy per noise power ratio ($E_b/N_0$), fading index(m). The results show that there is a substantial enhancement in performance by employing an MRC diversity or a CCI canceller. Additional improvement can be obtained when the MRC diversity and the CCI canceller are adopted in cascade form. Consequently, we expected that proposed system structure is reliable to the voice communication system in Nakagami fading, multi-user interferences and multipath channel.

As the society is developed, the role of fire departments is expanded to the service for the entire society or community from preventing and extinguishing fire. However, since there has not been any study on the space of fire-departments, it is indispensible to focus studies on the cases of domestic fire-departments first of all. Accordingly, this study has analyzed the cases of fire-departments in Incheon to draw the following outcomes of spatial characteristics. First, the arrangement of 8 fire-departments in Incheon was categorized into the styles of “ㅡ”, “ㄴ” and “ㅁ” based on the condition of site and spatial structure. Second, with the application of movement-lines of fire-fighters, officials in charge of administration in fire-departments and visiting civilians, the zone and movement-line of fire-departments was categorized into the styles of “separate” and “mixed” and the characteristics of each have been suggested. Third, the real spatial-structure of fire-departments was drawn into the areas of fire-scene response and support, standby and living, and administration, to which was added the infection control-room, equipment cleaning-room, emergent cleaning-room, first-aid cleaning and disinfection room and first-aid kit keeping-room. Fourth, the average area and the net area of Fire-departments in Incheon were found to be 4,113.02㎡ and 2,772.86㎡ respectively, and the gross area and the average area per person 31.19㎡과 17.0㎡.
연구개발특구제도가 기업의 투자와 고용에 미친 효과 분석
소준영,송헌재 한국재정학회 2020 재정학연구 Vol.13 No.2
This article examines whether the R&D Innovation Cluster zone program of South Korea has affected the firm’s investment and employment decision using firm level panel data. The estimation results show that this program significantly increased the investment and employment of the firms resided in the zone. Further, we examines whether the tax incentive of the program makes additional impact by comparing firms with tax exemption and firms without the tax benefit only for firms resided in the zone, but we do not find an supportive evidence that this tax incentive has further impact on the investment and the employment of zone resided firms. With these results we conclude that the R&D Innovation Cluster Zone programs are effective, and main driving force of the success is not the tax incentive but the other supports of the program such as to build R&D favorable business environment. These findings suggest that it is more important to provide R&D friendly environment in order to encourage firm’s R&D investment. 본 연구에서는 연구개발특구진흥재단의 입주기업 실태조사자료와 NICE평가정보의 기업공시자료를 이용하여 연구개발특구제도가 기업의 투자와 고용에 미치는 효과에 대해 분석하였다. 실증 분석결과에 따르면 연구개발특구에 입주한 기업이 그렇지 않은 기업과 비교하여 투자와 고용 활동을 더욱 적극적으로 하고 있음을 실증적으로 확인하였다. 다음으로 연구개발특구에 입주한 기업만으로 한정하여 첨단기술기업 등에 대한 법인세 등의 감면세제지원이 이들 기업의 투자와 고용을 더욱 증대시키는 추가적인 효과가 있는지 살펴보았는데 여기에서는 유의한 효과를 발견하지 못하였다. 그러므로 본 연구에서 발견한 연구개발특구 입주효과는 연구개발특구 지정으로 연구개발 친화적인 환경을 조성함에 따라 개선된 기업 환경을 적극적으로 활용하고자 하는 기업들의 집적효과로 이해하는 것이 더욱 타당할 것이다. 이러한 결과들은 연구개발특구제도를 통해 기업의 연구개발 투자활동을 촉진시키기 위해서는 세제지원보다는 연구 친화적 인프라 환경을 조성하는 지원책이 더 효과적일 수 있다는 시사점을 제공한다.

This author made comparison and analysis on the direction of development of vocation training facilities in Korea and Japan and its architectural characteristics in order to use it as basic data for establishing direction for construction of vocational training facilities for the disabled. And in consequence the following conclusion was drawn:First, population of the disabled was compared with quota of the vocational training facilities for the disabled and it was found that in terms of capacity for accommodation of disabled students Japan was twice as much as Korea in scale.Second, this author made detailed sectioning of space for vocational training facilities on the basis of space for vocational training, support, living, welfare and benefit and sports. Further this author classified lay out of buildings, composition of plane and patterns according to specified space on the basis of route of mobility between the user and operator/manager, composition of functional space, relationship of location among different space, forms of space and area etc. and then proposed for its specific characteristics.Third, this author made comparison and analysis of area of land, gross area, specified area according to different cases in Korea and Japan and then presented characteristics of area on the basis of composition of space.

The objectives of the study are to get the basic architectural information, perspectives and directions of Welfare Centers for the Disabled in Korea, throughout the survey and analysis of Welfare Centers for the Disabled in Japan. The results of the study area as below: First rehabilitation centers in Japan are classified into two types, type-A (regional) and type-B (local), according to the range of covering area, the size and the service. The study presents the required space and the organization of spaces in both types. Second, there is a type-A center in every 3,100 thousand population and 100 thousand the disabled, there is a type-B center in every 60 thousand population and 20 thousand in Japan. Finally, the average area of normal type-A centers is 5,200㎥ and average area of the smaller, which has the smaller sport facilities, is 3,100㎥. In type-B centers, the average area of the normal is 1,300㎥, and the other is the range of 450㎥and 550㎥.
