WCDMA 시스템에서 radio link간에 data를 주고 받고 신뢰성 있는 data를 검증하는 layer가 RLC이다. RLC에서는 전송 측에서 전송한 data가 수신 측에 잘 전송이 되었는지 status report를 확인을 받고 전송이 이루어지지 않았을 경우 재전송을 한다. 재전송 메커니즘에는 poll 및 status 관련 timer가 존재하면 이러한 파라미터값을 적절히 사용하지 않으면 불필요한 data의 재전송으로 인한 radio resource 낭비 및 시스템 throughput에 영향을 준다.

지난 4월 13일 실시된 16대 총선에서 방송사와 조사기관들이 공동으로 조사하여 발표한 선거예측조사에서 많은 오류가 발생하고 이로 인해 표본조사에 대한 신뢰성에 큰 문제가 제기되었다. 이에 향후 선거계측조사의 신뢰성을 회복하고 보다 정확한 예측을 위해 기 발표된 예측 조사내용을 다각도로 심층분석하고 조사의 오류가 발생한 원인과 이를 해결하는 방안을 제시하였다. 아울러 이번에 처음으로 실시된 출구조사에 대한 문제점과 개선 방안도 함께 살펴보았다.

The reference scheduler presented by IEEE 802.11e standard is inefficient because it polls all admitted stations in the same interval. It increases poll overheads and waste time. In this paper we proposed an efficient scheduling algorithm to improve the aggregate throughput and the number of admitted stations.

본 연구에서는 2006년 5월에 KBS/SBS에서 공동으로 실시한 제4회 전국동시지방선거 출구조사 과정을 소개하는 동시에 출구조사 자료를 통해 투표자의 특성(성별 및 연령대)에 따른 투표성향과 시간대별 투표자 특성을 정리하고, 출구조사 선거구별 득표율을 예측치와 실제 개표결과를 비교하여 출구조사의 예측오차를 살펴본다. 이를 위해 이번 출구조사에서 적용된 전반적인 표본추출방법 및 실사과정을 정리하고, 출구조사에서 발생한 전체 오차를 편향과 표본추출오차로 분리하여 오차의 특성을 분석한다. 편향 발생원인 중 하나로 볼 수 있는 표본의 대표성을 검토하기 위해 출구조사 표본을 선관위에서 집계한 투표자 투표율 분석결과와 비교하여 평가한다. 아울러 이번 지방선거 출구조사에서 적용된 '층화 후 정렬계통추출법'에 따른 분산추정법을 적용하여 출구조사의 정확성을 표본추출오차 관점에서 살펴본다.

The objective of this study was to investigate polymorphisms of BMPRIB (bone morphogenetic protein type IB receptor) gene and its effect on litter size traits in sheep. Three populations including 101 Small Tailed Han sheep, 79 Poll Dorset and 81 hybrids (Poll Dorset${\times}$Small Tailed Han sheep) were used to detect the polymorphisms in exon 6 region of sheep BMPRIB gene. A fragment of approximately 190bp was amplified by one pair of primers, the polymorphism was revealed from the analysis of three populations by the technique of PCR -SSCP, and a mutation from A to G at 746 of the coding region was confirmed by sequencing in several individual. Statistical results indicated the distribution of allele B (with a A$\longrightarrow$G mutation) and A (without mutation) or genotype AA, AB and BB frequencies differed in three populations. BB genotype (44.55%) and B allele (66.34%) frequencies of Small Tailed Han sheep were higher than those of the others. Analysis of variance showed that the polymorphism of BMPRIB gene was associated with positive effect on litter size traits. The means of genotype BB and AB were about 1.04 and 0.74 more than genotype AA for litter size (p<0.05). Analysis of BMPRIB genotype effects on litter size in three populations indicates the existence of genotype BB or B allele increases the litter size. It suggested that the polymorphism in exon 6 (at 746 in the coding region) of sheep BMPRIB gene may be used as a marker for early selection of prolificacy in sheep.

Previously, studies concerning the Russian dialects have been mainly focused on northern, central, and southern dialects limited to western Russia of Ural Mountains. On the contrary, the Siberian and Far-eastern dialects have been completely disregarded to the main stream of the Russian dialectology. As a result of a poll concerning this idea, the majority has answered that there is no dialect in Siberian and Far-east regions. Though the reasons for the outcome of the poll could vary, it could not be simply accepted that there is no dialect in such vast regions. Thus, a survey has took place to examine the existence of dialects in the regions of Siberia and Far-east. The first phase of the survey inquired the residents of the regions including Siberia and Far-east to respond to questions regarding 83 vocabularies on wedding in contrast to the regions covering western Ural and Moscow. The 23 informants were residents of the concerned regions who have come to visit Pushkin National Institute of Russian Language and, others, Korea. The questionnaires used in this survey were partly obtained from the questionnaires originated by the Language Institute of St. Petersburg National University. Although the limited range of regions and a small number of respondents who partook in this survey could raise some issues on the table, it is relevant to understand that this study would open up the path for the development of studies concerning regional dialects in the future.

A new classification system with 9 main categories and 56 subcategories for the Open Korean Knowledge Dictionary is proposed. The classification system setup is to prepare for the standard classification system to be used to manage effectively vast of terminologies which were published in the Open Korean Knowledge Dictionary and is meant to enhance the fifteen-year old classification system for the standard korean great dictionary to match up to the trend of the modern terminology. The new terminology classification system covering all the academic areas such as humanity, sociology, politics, science, medicine, agriculture, engineering, etc, is designed and proposed after investigating several classification systems. The classification system setup procedures follow as ${\circ}$ The classification system is designed and planed by both the classification system and the academic expert. ${\circ}$ Classification system design covers all the academic areas following National Science and Technology standard classification system after investigating several classification systems such as the National Research Foundation, National Science and Technology Standard Act, Ministry of Knowledge Economy. ${\circ}$ Poll and survey is made to collect comments from total 93 members of several academic areas. ${\circ}$ The poll result is reviewed among working group members and utilized to update the new terminology classification system. Reclassifications are made for the around 200,000 terms in electricity, computer, medicine, pharmacy, biology, and economics according to the new terminology classification system.

본 연구의 목적은 선거여론조사에서 유권자의 사전 태도 및 투표 의향과 실제 투표 행동간의 상관성을 분석함으로써 투표결과에 대한 선거여론조사의 예측력을 높이는 방법을 탐색하는 것이다. 지지 후보, 정치적 자기 신뢰와 효능감 및 현재의 이슈에 대한 입장을 통해 사전 태도를 측정하고 투표 참여와 관련하여 투표 의향, 과거 선거에서 투표 참여 및 선거에 대한 관심 정도를 측정했다. 실제 투표행동은 개표 후 사후조사에서 투표 참여 여부와 투표 후보를 질문했고 사전조사와 투표 행동 간의 상관성을 분석하기 위해서 동일인을 대상으로 사전, 사후조사를 실시했다. 사전조사의 투표 의향, 선거 관심도와 과거 투표 참여 등이 실제 투표 참여와 상관성이 컸으며 사전조사의 지지 후보와 실제 투표후보 간에는 변동이 거의 없었다. 또한 인구 특성과 현안에 대한 태도를 통해 지지 후보 무응답자의 투표행동을 예측할 수 있음을 입증했다.

South Korea has achieved remarkable social and economic development together with the process of democratization over the past 20 years. In the democratic process in South Korea, ordinary people have actively participated in conventional political activities such as elections. But recently, one of the salient phenomena is that the public have been showing political apathy associated with a light poll. Especially, the most serious concern in the political environment of South Korea is that young voters (e.g., 20-30s) have serious political apathy leading to low voter turnout. Regarding this concern, many political scientists argued that this political phenomenon is not only the case in South Korea, insisting that many consolidated democratic countries such as European countries and the US have the same problems. However, South Korea has contained different factors (e.g., historical, culture, social, and political differences) leading to political apathy and light poll. Unfortunately, no one has clearly explain the phenomenon. In fact, in order for scholars to understand and explain these concerns, they should carefully look at the phenomenon with diverse perspectives and approaches. The main purpose of this paper is to explain why the digital generation has political apathy and are reluctant to participate in political activities such as voting. Using causal loop analysis which is based on systematic thinking, we not only analyzed the pattern of the digital generation' political participation with regard to diverse perspectives, but also attempted to draw new political implications from the analysis. Based on our analysis, we tried to suggest some implications for political stability and development in South Korea in the future.
