This paper aims at exploring the multi-scalar processes through which the Gumi Industrial Complex was developed in the late 1960s and the early 1970s. Existing studies, influenced by the "Developmental State Thesis", tend to see the industrialization processes of South Korea either by focusing on the socio-politico-economic processes at the national scale or in terms of the plan rationality of the national bureaucrats. This paper, however, denies this perspective on the basis of the strategic relational approach to the state and the multi-scalar perspective. In particular, it argues that the state actions for national industrialization have been the outcome of complex interactions, conflicts and negotiations among social forces, acting in and through the state, and at diverse geographical scales. This paper attempts to empirically prove this argument on the basis of a case study on the construction processes of Gumi Industrial Complex. The development of Gumi Industrial Complex cannot be solely explained in terms of either the plan rationality of the national bureaucrats or the political motivation related to the fact that Gumi was the hometown of President Park Jung-Hee. This paper argues that the development of Gumi Industrial Complex was heavily influenced by the role of the following actors; place-dependent local actors in Gumi and the multi-scalar agents, such as the Korean-Japanese businessmen and the national parliament members elected in the Gumi electoral district.

This study analyzes the characteristics of the evolution process of the Gumi National Industrial Complex as well as its external and internal drivers based on the cluster adaptation cycle model. The Gumi National Industrial Complex has made remarkable progress through expansion in spatial and industrial realm and has become a representative IT industry cluster in Korea. It evolved during a growth period from the 1990s, a maturity period from the mid-2000s, and a mature stagnation period from the mid-2010s. But it has now entered a period of decline. While external drivers at the international and national level greatly influenced the Gumi National Industrial Complex in its evolution from foundation-building to maturity, internal drivers such as the outflow of large firms as well as a lack of SME research capacity and institutional base have added to the management difficulties of SMEs in the mature stagnation period. Therefore, in order for the Gumi National Industrial Complex to move into a revitalization period that strengthens resilience against external shocks, it is necessary to enhance the capacity of SMEs by expanding the roles of the central government, local government, and support agencies. In addition, it is necessary to create and embed strong medium enterprises within the Gumi National Industrial Complex, so that the Complex can be reborn as a sustainable innovation ecosystem.

Objectives: This study was conducted to evaluate the prevalence rate of multiple chemical sensitivity/idiopathic environmental intolerance(MCS/IEI) among workers in the Gumi industrial complex around the region of accidental release of hydrogen fluoride in 2012. Materials: We evaluated MCS/IEI using the Korean version of the Quick Environmental Exposure and Sensitivity Inventory(QEESI). A total of 535 workers at six manufacturing companies in the Gumi industrial complex were investigated using self-administered questionnaires from February to March 2015. After exclusion of incompletely answered questionnaires, 271 were analyzed. Results: The prevalence rate and proved positive rate of MCS/IEI were 5.9%(16 out of 271) and 3.7%(10 out of 271), respectively. The scores of chemical intolerance, other intolerance, symptom severity and life impact were significantly higher(p<0.05) in females than those of males. In terms of masking index scores, males showed significantly higher(p=0.003) than female. The self-reported MCS/IEI prevalence rate, 7.7%, of workers exposed to hydrogen fluoride in 2012 was higher than no-exposure group(5.6%), but not statistically significant(p=0.815). Conclusions: Although the prevalence rate of MCS/IEI symptoms of workers exposed to hydrogen fluoride gas in 2012 was not significantly higher than no-exposure group, it is necessary to conduct follow-up study on the exposure group of hydrogen fluoride.

In this study CALPUFF modeling was performed to predict a contribution of a separate single point pollutant source as well as of total point pollutant sources of major synthetic fiber manufacturers in Gumi national industrial complex to atmospheric trimethylamine concentration of the same area. In addition, a contribution of the separate single point pollution source to the atmospheric trimethylamine concentration of the same area was estimated relatively to the total point pollutant sources. As a result of the CALPUFF modeling, the maximum atmospheric concentration of trimethylamine in Gumi national industrial complex was appeared upon improving T company emission facility frequently in complex 3 in winter (January) and spring (April) while frequently in complex 1 in summer (July) and autumn (October). Besides, the predicted range of the maximum atmospheric concentration of trimethylamine in complex 1 was improved upon improving its emission facility. However, even though in complex 3 the upper bound of the predicted maximum atmospheric concentrations of trimethylamine was increased upon improving T company emission facility, the predicted value of their second upper bound below the upper bound was very similar to the upper bound of measured atmospheric trimethylamine concentrations in Gumi prior to improving its emission facility. Thus, the effect of improving T company emission facility was estimated huge in complex 1 while it was trivial in complex 3. These maximum concentrations of trimethylamine predicted to estimate the expected contribution of total point pollutant sources by CALPUFF modeling showed the similar values to those measured in the region of Gumi. Therefore, the expected contribution of total point pollutant sources to atmospheric trimethylamine concentration in the area of Gumi was validated.

Although industrial complexes have played as an engine of the Korean economy for the last 40 years, the majority of industrial complexes shows limitations to the continuous growth such as a lack of innovation capabilities and social capital, conceived as a key to transforming into clusters of innovation. To overcome those problems, the Korean government embarked on the cluster policy from the mid 2000's, focusing on promoting the endogenous development capabilities of individual industrial complexes. Drawing upon the in-depth case study of the Gumi IT cluster, one of the representative large-scale industrial complexes in Korea, the authors conclude that the cluster policy has contributed to making the Gumi IT cluster enhance the capabilities of endogenous development through the facilitation of self-organizing learning communities within the cluster.

In this study CALPUFF modeling was performed to establish a correlation between regions of frequent civil odor complaints near Gumi national industrial complex and odor-emission facilities of synthetic fiber manufacturers in the same area as main acetaldehyde-emission point sources. As a result of the CALPUFF modeling, the maximum concentration of acetaldehyde in Gumi national industrial complex was reduced from O ($10^{-5}g/m^3$) to O ($10^{-6}g/m^3$) upon improving emission facilities of T company so that the maximum concentrations of acetaldehyde frequently appeared in complex 3. In addition, the predicted range of the maximum acetaldehyde concentration in Gumi national industrial complex was also improved in comparison with that prior to improving emission facilities of T company. These maximum concentrations of acetaldehyde obtained to estimate the expected contribution of total acetaldehyde point source by CALPUFF modeling showed the similar values to those measured in 'HAPs investigation in the region of Gumi-Daegu' and were consistent to the trend of civil odor complaints. Therefore, the expected contribution of total acetaldehyde point source was validated. The relative contribution of T company upon improving its emission facilities was predicted to be lowered by more than factor of two, compared to that prior to improving its emission facilities. To the contrary, the relative contribution of W company upon improving emission facilities of T company was predicted to be increased by more than factor of two, compared to that prior to improving emission facilities of T company. This indicates that the contribution of aldehyde point sources of W company was relatively increased upon improving emission facilities of T company.

This study was carried out to evaluate the temporal, spatial, and seasonal variations of VOC, and to characterize the VOC concentrations in two large industrial complexes located in Pohang and Gumi cities. Twenty -four hours continuous sampling of selected VOC was made with STS 25 sequential tube samplers and double-bed adsorbent tubes. Air samples were collected every three hour interval for 7 consecutive days in each site during summer and winter. VOC were determined by thermal desorption coupled with GC/MS. A total of 27 VOCs of environmental concern were determined, including aliphatic, aromatic and halides. Generally. concentrations of toxic VOC were higher in Gumi than Pohang, and VOC levels in industrial areas were typically several-fold higher than those in residential areas. The most abundant VOC appeared to be toluene for both cities. However, chlorinated VOC were higher in Gumi than Pohang, while aromatic VOC were more abundant in Pohang than in Gumi. Two cities showed relatively different variations of VOC concentrations within a day. It is likely that traffic related sources are major factors affecting the VOC in Pohang, and industrial solvents usages are important sources in Gumi. These results imply that the occurrence and levels of atmospheric VOC are strongly dependent on the type of industries in each city. Therefore, in order to develop any control strategies or to establish the priority rankings for VOC in large industrial complexes, the type of industries and the occurrence of VOC in the atmosphere should be taken into consideration.

This study analyzed the changes in the industrial environment surrounding the Gumi region and the status of the industrial crisis in the Gumi area amid such changes. The Gumi region is experiencing a more turbulent period than ever in the environment changes at the international, national and local levels, such as the transition to the Fourth Industrial Revolution, the weakening of the competitiveness of key industries including mobile devices and displays, and the moving-out of core companies such as Samsung and LG Group. Accordingly, efforts have been made to diversify the industrial structure by fostering industry of automobile parts, high-tech medical devices and carbon materials to cope with and adapt to environmental changes at the regional level. However, the Gumi region is still locked in to the mono-cultural, large enterprise-dependent industrial structure centering on the mobile and display sectors, failing to overcome the regional industrial crisis and stagnating the overall local economy. The relocation of large companies began to increase in the 2010s, reducing the protection of large corporations against environmental changes at the corporate level. As a result, the crisis factors of small and mediumsized enterprises are gradually expanding to the national and international scale and working more complexly, which is beyond the level they can afford. So it is highly likely that the current industrial crisis will deepen. Therefore, it is necessary to strengthen the resilience to adapt to changes in the environment when it comes to overcoming the industrial crisis in Gumi region. To this end, it is necessary to improve innovation capabilities and diversify businesses based on convergence and complex technologies at the enterprise level, and to be selected as a special crisis response area aimed at creating an innovative ecosystem through autonomous resonance of companies and industries at the local level.
