우리나라의 수자원정책이 과거 개발위주의 정책에서 수요관리 중심의 정책으로 전환됨에 따라 제한된 수자원의 효율적인 활용 차원에서 수자원 개발 및 관리계획 수립의 기초정보인 용수이용량 자료의 신뢰성 확보가 중요하게 되었다. 용수 이용량은 생활, 공업, 농업용수로 대별하여 산정하며 이들 중에서 특히 농업용수의 이용량을 상대적으로 산정하기 어렵다. 농업용수 이용량 산정시 고려되는 인자는 자료의 신뢰성이 우선되어야 수자원계획과 관리에 효율적으로 대처할 수 있을 것이다. 따라서 본고에서는 이러한 농업용수 이용량 산정을 위한 조사인자의 획득 방법과 체계를 다룬 "용수이용조사 합리화 방안 연구(3차)" 보고서(2003. 11, 건설교통부)의 내용을 중심으로 정리하였다. 용수이용량 산정을 위한 조사인자는 수자원계획 및 관리차원에서의 활용측면과 대국민 신뢰도 확보 등 홍보효과 측면 등을 감안하여 종합적으로 고려하였으며 용수수요량을 추정할 경우 필요한 인자에 대해서는 "수자원장기종합계획(2001. 7, 건설교통부/한국수자원공사)"에서 제시된 산정방법을 기준으로 하여 결정하였다.

In this paper, we study the dysfunctions of cryptography as dual-use goods and national domestic encryption control policies like key recovery system and decryption order. And we examine risks of the breach of the peoples' constitutional rights like the right to privacy in these policies and analyze these policies by applying the principle of the ban on the over-restriction. Finally, we propose the direction and requirements of our national domestic encryption control policy that maintains the balance of peoples' constitutional rights and investigatory powers.

This study analyzed the travel pattern with respect to use of public transportation by using transportation card data and presented the measures that can be used in a traffic policy. Transportation card data targeted Gyeonggi-Do area and as a utilization plan, a scenario that when a traffic policy decision maker improves bus stop facilities, the person selects a target site by using several variables that can be obtained from transportation card data was set and analyzed. The analysis result showed that K means cluster analysis which is decision making methodology and CHAID(Chi-squared automatic interaction detection) were used and it can be used usefully in policies in significance level of p <0.01. Also, based on these results, this study presented policy implications to be improved to actually use transportation card data in policies.

This study was conducted to develop a stem volume table for the Robinia pseudoacacia using stem taper equations. Specifically, Kozak's model was used in the estimation of each model parameter. The fitness of the estimated model was statistically verified and results of the residual analysis were found significant. Therefore, this model is considered applicable in the preparation of stem volume table for R. pseudoacacia. Furthermore, volume with bark and without bark table were developed based on the bark thickness estimation equation. The bark thickness estimation equation was also statistically significant, The stem volume table developed for R. pseudoacacia, which was first in Korea, is vital in managing these forests.

The purpose of this study is to develop a policy for the use of libraries and the promotion of the reading culture by the characteristics of communities, along with changes in social environment. It, therefore, analyzed the general condition of libraries, infrastructures for libraries and reading culture and the environment including the relevant legal system in Chungcheongnam-do, and examined the actual conditions of inhabitants' (students and general people) use of libraries and reading culture, and librarians. On the basis of the findings, it proposed the policy for the use of 20 libraries and the promotion of the reading culture, by dividing Chungcheongnam-do into six regional settlement areas, discovering policy tasks for the use of libraries and the promotion of the reading culture and collecting suggestions from librarians living in Chungcheongnam-do, to reflect the characteristics of communities in Chungeongnam-do, and therefore, suggest a desirable policy agenda. To pursue the policy proposed, it is necessary to reinforce the role and the status of libraries representing for metropolitan regions and to secure adequate personnel and budgets, in addition to effort made by libraries located at regional settlement areas.

This study attempts to provide a basis of selecting policy directions by empirically analyzing the effect of policy lending programs for SMEs in Korea using micro firm-level data and examining whether the programs contribute to improving the performance of SMEs and thus effectively carry out their missions. From the estimations using Ashenfelter(1978)'s approach, the evidence of differences in profitability enhancement between the benefited group and the never-benefited group could not be found in most cases. In addition, the estimations show that the policy lending program had stronger profit enhancing effects on the young SME group for the year that the program was applied, and indicate that the policy lending program might be the factor that makes the 'older' benefited SMEs to become addicted to the government policy and thus hinder them in their development to become more competitive and innovative. These results suggest that, when the programs are needed to support SMEs' financing, it is more effective to target the start-up companies or SMEs in their early stages rather than old SMEs.

This research presents the development of a certain highly efficient model for group security policy negotiation using mobile agents in the IPSec environment. The conventional IP security systems has some problems. A drawback to these systems is that the required policy between each security area is different. Another problem is not possible to guarantee whether a packet is transmitted through the same path by both directions and is protected by the same policy due to the topology of the network. Unlike conventional systems, the model developed herein can be resolved by using a mobile agent technology. If each domain needs a negotiation of security policy, a mobile agent manages the result of the negotiation in the form of a passport and guarantees the authentication and reliability each other by using the passport.

In this paper, We shed light on radio spectrum policy and strategic planning of the United States of America and draw some conclusions. First of all, as the radio technology evolves with time, paradigm shift from command & control to market-based approach and spectrum commons is reviewed. Strategic spectrum planning of USA is also analyzed and some suggestions are drawn. In particular, USA plan for developing dynamic spectrum access(DSA) technologies and implementation of the test-bed for the DSA spectrum sharing is discussed, which improves the spectral utilization. Finally We deal with spectrum re-farming issue for mobile broadband and implicative points based on the National Broadband Plan.

This paper attempts to explain the energy policy to respond to climate change that is debated in recent years. Especially by the case of Germany among the developed countries, the study investigates the direction, strategy and measure of energy policy which are implemented at the national level. The Energy policy of Germany revealed through this study will provide implications for the establishment and propulsion of the energy policy trying to overcome the crisis of energy resources and reduce greenhouse gas emissions in Korea. Firstly, this study reviews the major goal of German government's recent energy policy, and secondly discusses the various strategies and means of policy to achieve the main directions of Germany's energy policy.

본 연구는 중국의 3개지역 (Hebei, Shaanxi, Shanghai)에서 한 자녀가족정책이 둘째 및 셋째 아이의 출산에 미치는 영향을 헤져드(Hazard) 모델을 이용하여 분석하고 있다. 특히, 그 정책효과의 도시와 농촌간의 격차, 현재자녀의 성구조에 따른 격차의 연구에 중점을 두고 있다. 연구자료는 1985년에 완료된 제 1단계 중국의 출산력 심층조사 (In-Depth Fertility Survey in China)를 이용하였다. 이 분석은 해져드 모델에서 각 시점의 한 자녀정책 전인지 후인지를 나타내는 시간에 따른 변동변수(time-varying variable)를 설명변수중의 하나로 포함시키고 그와 더불어 그 변수와 도시/농촌 주거여부를 나타내는 변수와의 혼합변수 (Interactive term) 및 현존자녀의 성구조와의 혼합변수를 포함하므로써 가능하게 된다. 또한, 자녀의 사망력이 차후 출산력에 미치는 영향을 비슷한 방법으로 분석하였다. 연구결과로는 첫째, 둘째 및 셋째 아이를 출산할 확률에 있어서 도시와 농촌격차가 한 자녀정책 실시 이후 더욱 커졌다는 사실이다. 이러한 결과는 부모가 생각하는 자녀의 가치가 도시에서 더 많이 저하했음을 제시하거나 정부의 한 자녀정책이 도시에서 더욱더 엄격히 집행되고 있음을 시사하고 있다. 둘째, Hebei와 Shanghai에서는 남아가 없는 부부가 남아를 가진 부부보다 둘째 또는 셋째아이를 가질 확률이 훨씬 높게 나타났다. 한편, Shanghai에서는 한 자녀정책 이후 둘째아이의 출산률이 첫째아이의 성에 관계없이 매우 낮았다. 이는 전통적으로 내려오는 남아선호 성향이 아직 농촌지역에서는 강하게 영향을 미치고 있지만 도시지역에서는 강력한 정책집행이 이를 억누르고 있음을 시사하고 있다. 하지만 Shanghai에서도 첫째아이가 사망한 경우 그 아이가 남아였으면 죽은아이가 여아이였을 경우보다 둘째아이의 출산이 훨씬 더 빠르게 나타나고 있음을 볼 때 도시에서도 여전히 남아선호 성향이 잠재하고 있음을 간접적으로 보여주고 있다.
