In order to achieve the growth of traditional Chinese medicine, the chinese government has annually released "China Statistical Yearbook of Chinese Medicine" to the world since "State Administration of Traditional Chinese Medicine of the People's Republic of China" established in 1988. It is believed that the chinese government intends to secure the early dominance of the global medical market by systematic management of its own medicine infrastructures. Although the statistics of "China Statistical Yearbook of Chinese Medicine" weren't systematically organized at the beginning, it has becoming richer, more systematic, and more standardized in the data construction and system as time has passed. Furthermore, we can take a look at China's effort to take the initiative of oriental medicine by expanding investment in several core areas - medicine resources, operation of medical instruments, service, medicine education, medicine science research, and working expenses. This article will show how china has been trying to develop the chinese medicine, focusing on two parts. One is specific analysis of the book "China Statistical Yearbook of Chinese Medicine". It is divided into analysis of its construction system, the degree of data construction, and its statistical system. The other is analysis of annual changes in areas of medicine resources, operation of medical instruments, service, medicine education, medicine science research, and working expenses.

This paper presents a statistical analysis of the decision throeshold for derect-sequence spread-spectrum (DS-SS) prallel Pseudo-Noise (PN) code acquistion with a reference filter. The probabilities of detection and false alarm are derived, and the mean acquistion time is evaluated as a measure of the system performance in both nonfading and Rician fiding channels. From the statistical sresults, it is shown that in the performance analysis of the parallel acquisition system with reference filtering, the statistical evaluaion of the decision threshold seems more appropriate than the approximation of the decision threshold adopted in the other schemes[2,3].

In this paper, in order to develop the transmission system between the remote subscriber and the central office, the hardware and software implementation of a SMUX(Statistical Multiplexer)which can interleace eleven 16Kbps D-channels over a 64Kbps B-channel is obtained. As a result of this study, the high speed data transmission by the use of a dynamic buffer memory management algofithm for statistical multiplexing is realized. Especially a software architectur for interruption is proposed in order to improve performance of the transmission system more efficiently.

The difficulty of statistical survey has been weighted according to the development and the democratization of society. Since the survey cost increases and the quantity and the quality of the needed information become more diversity it is very hard to produce accurate and appropriate statistics in time. In order to cope with these survey conditions properly, we reviewed the statistical system of Korea and major countries, and proposed the improvable directions of our statistical system.

Since the restructuring in electricity industry, single utility company, KEPCO, was being unbundled horizontanly and vertically, which resulted in 6 generation companies. Hence, electricity statistics system leaded by KEPCO is no longer efficiently sustainable. By introduction of electricity market, the importance of statistical information is getting higher and higher. From now on, the leading role played in statistical system in electricity field should be switched from KEPCO to government. This paper looks into change in statistical work driven by electricity and provides alternatives applicable to new electricity market. In addition, this paper provides new standard form for the collection of statistical data and construction of statistical system.

The purpose of this paper is to suggest the problems of basic population data(1960-2005) and the data(2006-2050) of population projections reported by Korean National Statistical Office in November 2006. The errors on the basic population data can be easily checked by using the graphical analysis and the method of linear regression analysis. It is necessary to revise the population projections reported by Korean National Statistical Office.

This study described the application of constructivism and information technology for teaching simple random sampling. We considered more student's participation, more interaction, and more flow in their introductory statistics class. In addition, we presented a web-based teaching and learning system for simple random sampling to demonstrate.

Recent studies have revealed the efficacy of incorporating delayed channel state information at transmit side (CSIT) in transmission scheme design. This paper focuses on transmit precoder design to maximize the ergodic sum-rate in a two-user Multiple-Input Single-Output (MISO) system with delayed and statistical CSIT. A new transmit strategy which precodes signals in all transmit slots is proposed in this paper, denoted as all time-slots precoding Alternative MAT (AAMAT). There is a common procedure in conventional delayed-CSIT based schemes, which is retransmitting the overheard interferences. Since the retransmitting signal is intended to both users, all previous schemes tend to use only one antenna. We however figure out an improvement in spectral efficiency could be realized if all antennas can be utilized. In this paper, we detail the design of the procoder which enabling all antennas and also we compute a lower bound of the ergodic sum-rate in an ideal condition. In addition, simulation results demonstrate the superiority of our proposed scheme.

정보화시대의 발전과 더불어 우리 일상생활에 친숙하게 다가온 기술 중의 하나가 지리정보시스템(Geographical Information System: GIS)이다. GIS는 공간(지표, 지하, 해양 등)상에 분포하고 있는 정보에 대해 여러 종류의 세밀한 지도를 이용하여 효율적으로 사용자에게 제공하여 관리하는 종합정보기술이다. 통계 데이터 중에는 지리정보를 가지고 있는 경우가 상당히 많다. 하지만 지리정보를 갖는 통계 데이터의 탐색적 자료분석(Exploratory Data Analysis)을 위한 Visualization 기법에 대해서는 별로 연구된 바가 없다. 본 논문에서는 GIS를 위한 벡터맵(vector map)의 간단한 제작방법과 GIS의 개발방법, 그리고 탐색적 자료분석을 위한 Visualization기법을 소개한다.

Distributing information on the internet is common in our daily life. In the past, e-mail has been the primary choice of exchanging information, but instant messengers are gaining popularity abroad and domestically because of their immediate responses. Instant messaging has become the fastest growing communication technology in recent years. Instant messaging is effectively a chat room for two people. Users that have accounts with the same provider are able to send messages via computer in real time. Instant messaging has exploded into the business world as companies now utilize the technology for everything from interoffice communication to client/customer communication. In this paper, we propose a method of instant messenger system design for effective collaboration of statistical data collection.
