Till now, the roles of a tradition market were a circulation of the necessities of life, a employment market of local society, a center of community, and a main structure of local economy. Recently, these tradition market is on the decline because it couldn't cope with the internal and external changes. It is recognized that these phenomenon is a factor of economy unbalance. So, to activate the local economy, tradition market should be promoted. Therefore, external changes such as the increase of competition intensity and the changes of consume pattern, internal changes such as the deterioration of facility and old fashioned management were analysed. The activation plan of traditional market were suggested through the decision index for the tradition market in this study.

Local anesthesia known as the safe and essential procedure to control pain in dentistry may cause sensory changes such as paresthesia or altered taste at the affected sites after even successful local anesthesia. Although the prognosis of the nerve injuries after local anesthesia is favorable, it might cause prolonged problems such as dysesthesia. The lingual nerve is a single fascicle at the level of the lingual among 1/3 of patients and more movable during regeneration compared to the inferior alveolar nerve after the injury. As a result, the lingual nerve is more vulnerable and has poorer outcomes. More vigilant clinical considerations are required to the lingual nerve injury after local anesthesia. Generally, more than 80% of cases are spontaneously resolved within 2 weeks after the local anesthesia even without any specific treatment. However, the patient having long lasting abnormal sensations more than 2 weeks needs specialists' care for further assessment. In case of dysesthesia which is a symptom of neuropathic pain, immediate referral to specialists is mandatory. The exact mechanism, how to prevent its occurrence, or specific treatments of the nerve injury related to the local anesthesia have not been elucidated. To prepare clinical or medicolegal problems, many cautious considerations are given to the patients who complain sensory changes after local anesthesia.

Extension service in Korea has radical changes in accordance with local autonomy acts, 1994, and reformed rural development acts, 1995. According to these acts, the role of the central government is to arrange local extension service carried out by local extension office, to present basic plans on technical knowledge diffusion or farmers training to local government, and so on. Local extension office is a part of local government, and extension service is commited to the local government.

As interest in social network analysis increases, researchers' interest in detecting changes in social networks is also increasing. Changes in social networks appear as structural changes in the network. Therefore, detecting a change in a social network is detecting a change in the structural characteristics of the network. A local change in a social network is a change that occurs in a part of the network. It usually occurs between close neighbors. The purpose of this paper is to propose a procedure to efficiently detect local changes occurring in the network. In this paper, we divide the network into partitioned networks and monitor each partitioned network to detect local changes more efficiently. By monitoring partitioned networks, we can detect local changes more quickly and obtain information about where the changes are occurring. Simulation studies show that the proposed method is efficient when the network size is small and the amount of change is small. In addition, under a fixed overall false alarm rate, when we partition the network into smaller sizes and monitor smaller partitioned networks, it detects local changes better.

This paper analyzes job creation when the Korean economy transitioned to a knowledge economy from the 1990s to the 2010s. During this period, the ratio of service to manufacturing jobs increased, knowledge intensive industries grew, and job creation became geographically concentrated around Seoul. The changes slowed down in the 2010s, and overall job growth weakened. To analyze the effect of job creation driver industries during this period, the main part of which are knowledge intensive tradable service industries, on local service job creation, I use a modified version of the local labor market of Moretti (2010). I analyze the job changes during 1995-2005 and during 2006-2016 in 237 Si-Gun-Gu areas in the Census on Establishments datasets. I find that one manufacturing job creates 0.5 local service jobs and that one tradable service job creates 1.1 jobs within Gu areas of metro cities and 2.3 jobs in Si-Gun areas. The job creation relationship between the tradable and local service sectors was not altered in this period. As more jobs were created in the tradable sector driven by the transition to a knowledge economy, job creation overall remained active, with the opposite also being true.

This paper investigates the evolution of 'inter-firm' technology transfer in the Thai automobile industry, which has gradually been integrated into global production network of some specific automotive models(one-ton pickups). This paper discusses the linkage between the role of automobile assemblers in transferring technology and the way their strategic changes bring about heightened demands on the technological capacity of suppliers and the contents of technology transfer. With higher competition at the global level, local suppliers are required to improve their technical and managerial skills, especially in the area of 'product engineering' capability. The authors examine the ways local firms have adapted to these changes in their environments, as well as the ways they utilize inter-firm relationship with automobile assemblers as a means to improve their own technological capabilities. The dynamic process of capability formation in local parts firms, through intensive efforts and learning inducements brought about by inter-firm relationships, are also discussed.

This study analyzes the changes in individual local government's social spending from 1995 to 2004 in South Korea. Using the pooled time-series and cross-sectional data of 226 basic-level local governments, the resulting analyses of an error correction model are very interesting: First, a rising local population led to an immediate increase in social spending; Secondly, local governments gradually increased social spending when the elderly ratio had been high, but the levels of social spending in the previous year and local economy related spending level had been low. Thirdly, there were no spending changes associated with local elections and partisan politics. Fourthly, both cooperative and competitive intergovernmental relations had the most significant effect on the social spending and reduced geographical disparities in the level of spending across localities. In conclusion, this study suggests that we establish a more comprehensive intergovernmental network which lead to territorial justice in social welfare.

The land-use has changed rapidly during the last two decades in accordance with urbanization in the Seoul Metropolitan Region. As a result of these changes, the local climate has undergone changes as well. This study intends to define the land-use changes, and then to show how they have brought in significant changes in the local climates. Land-use changes in the study area so repidly that up-to date maps and documents are not available at present. Therefore, Landsat data for land-use classification and NOAA AVHRR thermal data for the temperature fields were analyzed. Additionary, to visualize the effect of the land-use on the local climate, computer-enhanced brightness temperatures, Green Belt and city boundaries were overlaid on land-use patterns obtained from satellite images using GIS techniques. The results of analysis demonstrate that Green Space in the Seoul Metropolitan Region decreased from 94% to 62% while urban land-use increased ten times, from 4% to 39% for the period of 1972-1992. The resulting disappearance of biomass caused by land-use changes may have implications for the local-and micro-climate. The results show that the local climate of the study area became drier and warmer. This study also suggests a need for further studies of man's effects on local climate to minimize adverse influences and hazardous pollution and efficacious ways for urban planning.

Global environmental changes have the capacity to make dramatic alterations to floral and faunal composition, and elucidation of the mechanism is important for predicting its outcomes. Studies on global climate change have traditionally focused on statistical summaries within relatively wide scales of spatial and temporal changes, and less attention has been paid to variability in microclimates across spatial and temporal scales. Microclimate is a suite of climatic conditions measured in local areas near the earth's surface. Environmental variables in microclimatic scale can be critical for the ecology of organisms inhabiting there. Here we examine the effect of spatial and temporal changes in microclimates on those of carabid beetle communities in Hyangnobong, Korea. We found that climatic variables and the patterns of annual changes in carabid beetle communities differed among sites even within the single mountain system. Our results indicate the importance of temporal survey of communities at local scales, which is expected to reveal an additional fraction of variation in communities and underlying processes that has been overlooked in studies of global community patterns and changes.
