This study is to investigate spatial patterns of urban labor market growth driven by marketization process and its implication for understanding regional uneven development in post-reform China. Using a shift share analysis, it shows that the geography of employment growth in China's industrial labor market has closely interacted with the space economy of industrial output, which in turn indicates a deepening of economic reform. By decomposing net employment growth into output and productivity effects, it is shown that the non-state sector holds rapid growth of both output and productivity and contributes to net employment growth through positive net shifts. On the contrary, this study also presents that the state sector with relative decrease in output and productivity holds employment decline effects during the reform period. Since there is a significant spatial dimension for the trend above, it is contended that labor market dynamics together with space economy of industrial production play an important role in determining regional patterns of economic development. In addition, through situating this investigation in the context of structural and institutional changes in the reform period, our understanding of regional patterns of labor market growth will be much furthered.

The purpose of this study is concerned with the relationship between the location of industrial complex and regional changes. Yeochon National Industrial Complex(YNIC) was dedicated as an industrial site in 1967 according to a part of the Korean government's plan of developing for heavey chemical industry. Yeochun city has been changed with location and establishment of YNIC since 1969. The establishment of YNIC have influence upon the increase of population and employment, urban development, and growth of regional economy within research areas including of Yeochun city, Yeochun county, and Yeosu city. In addition, with the establishment of YNIC, the regional economical structure was progressed from farm and fishery oriented sector to manufacturing oriented sector, thus the petrochemical business related companies hold a majority among regional manufacturing structure. We used the shift-share analysis and regional growth rate differential analysis in order to examine the characteristics revealed in the transformation of employment and industrial structure. The petrochemical related manufacturing and construction industries provided a great influence on the growth of regional employment.

The purpose of this study is to analyze the impact of the Kwang-yang Iron and Steel Co.(KSCO) on the industrialization of the economic structure in Kwang-yang area. The research used the shift-share analysis and regional growth rate differential analysis. KSCO has influenced this area by changing the economic structure from traditional agriculture and fisheries to the manufacturing industry. KSCO also has influenced the population of Kwang-yang area. The number of employees grew from 594 in 1981 to 29,865 in 1992. However, after 1992, employee numbers decreased to 23,399 in 1998. KSCO was constructed in the region of traditional agriculture and fisheries in 1981. The social and economic status of the Kwang-yang area has changed greatly due to the growth of KSCO and the corresponding influx in population. KSCO has developed the related industry and changed this area into a booming industrial city. The number of employee has rapidly increased. At the end of the year 2000, 17,240 people work for KSCO and 39,593(28.7%) of the total population of Kwang-yang are related to KSCO.

The Material·Part·Equipment industry is mostly an industry centered on small and medium-sized enterprises (SMEs) and is an important industry for revitalizing the local economy, which is the source of manufacturing competitiveness. In this study, we tried to derive the implications necessary for the development of the Material·Part·Equipment industries by analyzing the competitiveness of the Material·Part·Equipment industries in the Chungcheong region. To this end, we analyzed the industrial development stage and competitiveness of each region (Daejeon, Sejong, Chungnam, and Chungbuk) based on business scale factor, industrial growth rate, industrial specialization, and regional competitiveness for the Material·Part·Equipment industries in the Chungcheong region. Using data such as the number of employees, the number of businesses, and the amount of production in 2014 and 2019, significant industrial groups by region were identified considering the level of industrial specialization and regional competitiveness. In addition, by identifying the positions of these significant industrial groups in the stage of industrial development, suggestions for the development of the Material·Part·Equipment industries in the Chungcheong region were presented.

망의 초기 설계 후에 입력환경의 변화로 인하여 망의 트래픽 요구량이 변화할 때 이를 용량 재분배를 통해 해결하는 방안을 제시하고 실험을 통해 분석해 보았다. 이용자 트래픽의 변동에 효율적으로 대처하고 이용자 연결의 통신 품질을 유지시키기 위하여 운용 경로 및 보호경로의 경로 및 용량 재할당방법을 연구하였다. 기존의 운용 VP만을 고려한 방안과 보호 경로의 용량을 함께 고려하는 방안의 비교를 통해 제안 방안의 특성을 조사하였다. 망의 제어 비용을 줄이기 위한 효과적인 방안으로 보호 경로의 용량을 운용 경로 용량보다 어느 정도 초과해서 할당하는 방안을 제시하였다. 제안 방안이 비록 소폭의 비용상승을 유발하지만, 트래픽이 빨리 변하는 환경에서는 오히려 비용 절감의 효과를 유발할 수 있어 효과적 방안이 될 수 있음을 알 수 있었다.

3GPP long-term evolution(LTE) band 2.3~2.4 GHz is adjacent to 2.4~2.5 GHz band for WLAN, and therefore compatibility study of the two systems is desirable. We propose a dynamic system simulation methodology to investigate the effect of WLAN interference on LTE systems. As capturing space/time/frequency changes in system parameters, the dynamic system simulation can exactly predict real system performance. Using the proposed methodology, we obtain LTE downlink throughput loss for the frequency separation between the two systems. Throughput loss under 1 % is obtained from guard band over 11 MHz(single channel allocation) or 10 MHz(three channel allocation).

동사 어간과는 달리 명사 어간은 그 자체로도 어형(word form)이 될 수 있다. 그러나 일반적으로는 명사 어간에 조사가 하나 또는 여러 개가 결합되어 어형이 형성된다. 이 논문은 이러한 명사 어형을 효율적으로 생성할 수 있는 규칙기반의 어형 생성 시스템 골몰(KORean MORphological system)이 어떻게 운용되는가를 시연하는 것이 그 목적이다. 이 시스템 변이형 포함한 기본 조사 108개를 기초로 하여 3,000여개의 복합형 조사를 생성한다. 그러나 국어의 명사 어간에 조사가 하나뿐 아니라 6개까지도 결합될 수 있으므로 명사 어형 생성과정에서 과잉 생성의 문제 발생한다. 생성 과정을 통제하기 위하여 골몰은 기본 조사에 결합 순서치(Order)를 할당하고 좌연접 요구(Requires) 조건을 명시하여 줌으로써 조사가 이미 도입된 좌측의 명사 어간과 적절히 결합될 수 있도록 장치되었다. 이 논문은 명사 어간과 조사의 이러한 결합 통제 조건을 논하고 골몰을 통해 명사 어형들이 어떻게 분석되고 생성되는가를 간단히 예를 보여 줌으로써 시스템의 충족성을 뒷받침한다.

As a travel demand management and environmental policy, the government actively promotes alternative work arrangements such as telecommuting. Against this backdrop, several empirical studies, which aim to verify the benefits of telecommuting, have been recently conducted. Little consensus, however, exists with respect to the defining, measuring, and forecasting telecommuting, although these are fundamental basis of policy evaluation and academic research. As a fundamental research for analyzing telecommuting impacts, this paper reviews various definitions regarding telecommuting, examines telecommuting penetration and level of telecommuting through review of available survey data in Korea, and forecasts future penetration. The result suggests that current home-based telecommuting penetration and level of telecommuting is approximately 0.5 to 1.1% and 0.2 to 0.5%, respectively, and is approximately 0.2% and 0.1%, respectively, for the center-based telecommuting. In addition, shift-share analysis shows that home-based telecommuting penetration in the Seoul Metropolitan Area in 2020 will be 1.3%, not much different with the current value. Consequently, current telecommuting penetration is much lower than the value that is fed to us by the media (10~20%), and the future prospect is also much lower than the goal of government (30~45%); thus, we can conclude that government's goal of telecommuting promotion is difficult to meet if active encouragement policy will not be introduced.
