본 연구는 성매매피해여성의 탈성매매경험을 분석하고 그 결과를 바탕으로 탈성매매 경험과정에 관한 이론 형성에 기여하고자 하는 목적으로 진행되었다. 연구방법으로 Strauss와 Corbin(1988)이 제시한 근거이론 방법을 적용하여 수행하였다. 본연구의 참여자는 탈성매매 되어 있는 여성 10명으로 탈성매매 기간 평균 2년 이상이 된 성매매 경험 여성들이다. 본 연구 결과 105개의 개념과 35개의 하위 범주와 17개의 범주를 도출해 냈다. 축코딩에서 패러다임에 의한 범주 분석결과, 탈성매매 경험의 인과적 조건으로 '잘못된 선택의 시작'이 나왔다. 중심현상으로 '심신의 황폐'가 나왔다. 이러한 중심현상을 가져오는 맥락적 조건으로는 '악순환의 고리에 얽매임', '무력감'이 나왔으며 중심현상에서 작용/상호작용 전략을 중재하는 조건으로서는 '불가피한 중단', '지지체계', '막연한 기대,' '퇴출됨', '역할감 생김', '가족의 그림자'가 도출되었다. 작용/상호작용 전략으로 '자성', '자포자기', '벗어나려 애씀'이며 결과는 '정체성혼란', '흔적에 대한 두려움', '성매매 재유입 여지', '벗어남'으로 도출되었다. 탈성매매 과정은 '심신의 황폐 단계', '단념의 단계', '의지 회복의 단계', '평범한 삶의 적응에 도전 단계'를 거치는 것으로 나타났다. 본 연구에서 성매매 피해 여성의 성공적 탈성매매 여부는 자신의 주체적 의지가 중요한 역할을 한다는 결론이 도출되었다.

The national emission from energy sector accounted for 84.7% of all domestic emissions in 2007. Of the energy-use emissions, the emission from mobile source as one of key categories accounted for 19.4% and further the road transport emission occupied the most dominant portion in the category. The road transport emissions can be estimated on the basis of either the fuel consumed (Tier 1) or the distance travelled by the vehicle types and road types (higher Tiers). The latter approach must be suitable for simultaneously estimating $CO_2$, $CH_4$, and $N_2O$ emissions in local administrative districts. The objective of this study was to estimate 31 municipal GHG emissions from road transportation in Gyeonggi Province, Korea. In 2008, the municipalities were consisted of 2,014 towns expressed as Dong and Ri, the smallest administrative district unit. Since mobile sources are moving across other city and province borders, the emission estimated by fuel sold is in fact impossible to ensure consistency between neighbouring cities and provinces. On the other hand, the emission estimated by distance travelled is also impossible to acquire key activity data such as traffic volume, vehicle type and model, and road type in small towns. To solve the problem, we applied a hierarchical cluster analysis to separate town-by-town road patterns (clusters) based on a priori activity information including traffic volume, population, area, and branch road length obtained from small 151 towns. After identifying 10 road patterns, a rule building expert system was developed by visual basic application (VBA) to assort various unknown road patterns into one of 10 known patterns. The expert system was self-verified with original reference information and then objects in each homogeneous pattern were used to regress traffic volume based on the variables of population, area, and branch road length. The program was then applied to assign all the unknown towns into a known pattern and to automatically estimate traffic volumes by regression equations for each town. Further VKT (vehicle kilometer travelled) for each vehicle type in each town was calculated to be mapped by GIS (geological information system) and road transport emission on the corresponding road section was estimated by multiplying emission factors for each vehicle type. Finally all emissions from local branch roads in Gyeonggi Province could be estimated by summing up emissions from 1,902 towns where road information was registered. As a result of the study, the GHG average emission rate by the branch road transport was 6,101 kilotons of $CO_2$ equivalent per year (kt-$CO_2$ Eq/yr) and the total emissions from both main and branch roads was 24,152 kt-$CO_2$ Eq/yr in Gyeonggi Province. The ratio of branch roads emission to the total was 0.28 in 2008.

The Korean New Car Assessment Program (KNCAP) is a program to evaluate the safety of automobiles. In the safety assessment method, there are frontal collision, partial frontal collision, side collision, pillar collision, and left stability in the collision safety category. Among them, Korean in-depth analysis data shows that there are a lot of side collision accidents and it is necessary to protect them. This study will analyze the side collision accident that occurred in actual traffic accident based on Korea In-Depth Accident Study (KIDAS) and investigate the effect of center airbag on passenger in under side collision. In addition, with simulated side collision scenarios in the various side impact directions, it was investigated how the center airbag affects the driver and passenger in terms of kinematic and injury levels.

Unbalance between user requirements and insufficient network resources makes a congestion. In the future since the communication networks will have very heavy traffic congestion will be more serious. The ATM networks was recommended to support the B-ISDN service for the future multimedia communication. In thie sense of congestion avoidance and recovery the ABR service category in ATM networks allows the feedback flow control mechanism to dynamically allocate the idle bandwidth of the network to users fairly and to control the network congestion rapidly In this paper we introduce a congestion control scheme using systematical approach to confirm robust stability with respect to unknown round trip delay for the network which has both unicast and multicast connections.

Since national mid-term target for GHG reduction was determined in 2009, various efforts in transportations have been prepared. Generally, the GHG emission of transportation is calculated using the emission factor published from IPCC guideline(2006). However, it is necessary to develop new emission factors considering the properties of transportation as well as fuel. In Korean railroad, main emission sources are the consumption of diesel and electricity from railcar operation. The GHG emission of electric-powered railcars can be estimated using national electric emission factor, but diesel-powered railcars show different trends. The purpose of this study was to establish the development plans of emission factors for diesel-powered railcars. As a result, the emission factors of diesel-powered railcars were classified into railcar type, engine type and life cycle, notch, load, and traffic volume. In future, several emission factors with this category will be presented quantitatively through field tests with the order of priority.

차종별 교통량자료는 자료의 출처별로 차종이 동일하지 않아 자료간 호환이 어려우며 이들 자료의 활용도 또한 매우 낮다. 특히, 고속도로의 경우에는 전수자료인 TCS 자료가 있음에도 불구하고 TCS의 타종분류는 차종 내에 승용, 승합, 화물차가 혼재 되어있어 실질적으로 활용도가 매우 낮다. 이에 본 연구에서는 각 출처별 자료들의 차종구분과 호환할 수 있도록 타종구분을 표준화하고 고속도로 톨게이트 유출입 차종별 교통량을 표준화된 차종별로 추정하기 위한 모형을 개발하였다. 즉, 톨게이트를 그 특성에 따라 몇 개의 카테고리로 분류하였고, 각 카테고리별로 각 타종의 구성비를 점추정량을 이용한 기법(산술평균, 기하평균, 조화평균)과 비모수적 통계기법인 붓스트랩을 이용하여 표준화 분류별 교통량을 추정하는 모형을 개발하였다. 그 결과 두 방법 모두 비교적 유의한 수준의 결과가 도출되었으나, 표본의 크기에 따라 발생할 수 있는 극단치에 대한 오추정 문제를 감안할 수 있는 붓스트랩기법이 우수한 것으로 나타났다. 본 연구의 결과로 향후 TCS 자료의 활용성 증대와 TCS 자료를 이용한 고속도로 구간교통량 추정과 고속도로 정기교통량 조사자료의 좀더 구체적인 비교가 가능할 것으로 기대된다.

CFR 서비스는 가장 최근에 제안된 ATM 서비스 범주의 하나이다. GFR 서비스는 ATM 네트워크에서 TCP/IP 트래픽을 효율적으로 지원하기 위해 ATM 포럼에 의해 최근 제안되었다. GFR 스위치 구현시, 효율적인 스케줄링 알고리즘은 최소 전송율 보장과 공평성 향상이 중요하다. 본 논문에서는 GFR 서비스를 위한 새로운 스케줄링 알고리즘을 제안한다. 제안된 스케줄링 알고리즘은 VC에 우선 순위를 제공한다. 버퍼에 태깅이 안된 셀 수가 적은 VC에 높은 우선 순위를 두어 낮은 우선 순위의 VC보다 우선적으로 서비스를 제공하여 VC의 MCR을 보장하고 공평성을 향상한다. 컴퓨터 시뮬레이션을 통해 TCP 수율과 공평성 지표에서 기존 스케줄링 방식보다 성능이 우수함을 보여주었다.
