The purpose of this study is to explore a spatial agglomeration characteristics and innovative milieu of the shoemaking industry in Seoul. In order to explain it, currently discussed dynamic agglomeration economies approach is applied and as an example, shoemaking industry in Seoul has been analyzed. The result of this research can be boardly summarized into two points. Frist, agglomeration economy is changing from urbanization economy to localization economy in this newly rising core of shoemaking industry which is Sung-Su dong area. Also, cooperative effects based on collective efficiency between companies and people are being generated within the area. This is largely affected by networking infrastructure between companies and people within the area, non-trade dependency and social capital acclamation. Secondly, the lack of institutional agglomeration formation in this area is considered to be the obstacle for the long-term development and innovation spin-off. This means recognition switch-over and institutional concern and support is needed in the future from the public sector.

The reduction of fishing grounds due to the establishment of EEZ system among China, Japan and Korea together with the depletion of fish resources by pollution of waters and successive reclamation projects along the east and the south coastal lines has made many problems in coastal communities including the decrease of population, the deepening aging phenomenon in the fishery society and the fall of relative income level compared with those of rural and urban residents. Especially, the income level of a fishing household is 90%. of a rural resident and 70% of a urban resident. The income of a fishing household consists of 55% of fishing income, 20% of a agricultural source, 20% of income from non-fishing areas, and 10% of transferred income. Compared with that of a Japanese fishing household which has more diverse income sources such as 62% of income coming from non-fishing areas through being hired in manufacturing firms, etc., that of Korean ones is highly dependent upon fishery and agriculture, so that the diversification of income sources is urgently needed, especially in non-fishing areas. This paper shows that as a model to upgrade fisherman's income level, firstly, it is necessary to enhance the value-added of fishing products through processing and new innovation of distribution process and, secondly, to promote tourism in fishing villages. To ascertain this model, a questionnaire survey to fishermen was carried out and showed that they expressed a strong support for the increase of income by the value-added process through processing and innovative distribution system and the active introduction of tourism in fishing villages. A case study on Gosan cooperative in Jeju was also introduced to identify the rationale of the suggested model and this study proved the validity of the model again. Conclusively speaking, to level up the fisherman's income requires the value- added activities through the introduction of product processing and new distribution system together with the introduction of marine tourism in fishing villages.

The CO preferential oxidation reaction (PROX) has been done using Cu catalytic active species supported on some of mesoporous silica materials which can facilitate the diffusion of the reactants in order to prevent the poisoning of anode active materials by CO molecules during driving polymer electrolyte fuel cells (PEMFC) in this study. As a result when SBA-15 with large pore used as a support showed excellent CO oxidation activity, especially the activity increased in proportion to the amount of supported Cu. Ti components which was inserted to increase the degree of dispersion of Cu, contributed to improving the performance for CO oxidation at low-temperature. The degree of dispersion of Cu ingredients was the best in the catalyst inserted 20 mol-% Ti into the framework of SBA-15, and CO oxidation activity was also improved.

This paper analyzed the relative efficiency of industrial complexes by type based on the DEA Model. In this analysis, the output and exports of 287 industrial complexes in 2017 were used as output variables, while the industrial land area and the number of employees in the same year were used as input variables. The results of the relative efficiency of industrial complexes by type were as follows: The relative efficiency of industrial complexes was affected mainly by type and the operating period of industrial complexes. In the types of industrial complexes, the most efficient industrial complex was the Urban, high-tech industrial complex, followed by the National industrial complex and the General industrial complex. Therefore, high-tech innovation and government support for industrial complexes would be necessary to increase the efficiency of industrial complexes. In the operation period of industrial complexes, relative efficiencies increased with longer operation periods. To maximize the regeneration effect of the old industrial complex, efficiency must be kept as a priority item of the old industrial complex regeneration project.

Natural antimicrobial substances are needed as alternatives to synthetic antimicrobials to protect against foodborne pathogens. In this study, a bacteriocin-producing bacterium, Bacillus subtilis HD15, was isolated from doenjang, a traditional Korean fermented soybean paste. We sequenced the complete genome of B. subtilis HD15. This genome size was 4,173,431 bp with a G + C content of of 43.58%, 4,305 genes, and 4,222 protein-coding genes with predicted functions, including a subtilosin A gene cluster. The bacteriocin was purified by ammonium sulfate precipitation, Diethylaminoethanol-Sepharose chromatography, and Sephacryl gel filtration, with 12.4-fold purification and 26.2% yield, respectively. The purified protein had a molecular weight of 3.6 kDa. The N-terminal amino acid sequence showed the highest similarity to Bacillus subtilis 168 subtilosin A (78%) but only 68% similarity to B. tequilensis subtilosin proteins, indicating that the antimicrobial substance isolated from B. subtilis HD15 is a novel bacteriocin related to subtilosin A. The purified protein from B. subtilis HD15 exhibited high antimicrobial activity against Listeria monocytogenes and Bacillus cereus. It showed stable activity in the range 0-70℃ and pH 2-10 and was completely inhibited by protease, proteinase K, and pronase E treatment, suggesting that it is a proteinaceous substance. These findings support the potential industrial applications of the novel bacteriocin purified from B. subtilis HD15.

The present study explores how the quality management rhetoric commonly used by Korean CEOs tends to be composed and perceived by the public. To this end, articles of the remarks of Lee Kun-hee, the second founder of Samsung, are analyzed. The results show a rhetorical structure of quality management where the CEO offers a persuasive theme (quality management for a super-class enterprise) and practical measures (innovation and performance-based promotion) while coping with a rhetorical situation (an economic crisis). A multiple regression analysis of the response of 308 Korean college students who watched a video of Lee's remarks indicates that the more conservative the viewers are and the more they perceive the CEO's charm and expertise, the more likely they are to support the CEO's quality management rhetoric. The conservative viewers favorably responded to the entrepreneurship in the quality management rhetoric, while the progressives recognized the rhetoric as part of Korean-style neoliberalism that alienates ordinary workers.

This study aimed to examine the effect of parentification on the smartphone dependency of upper elementary school children in double-income families and to verify whether ambivalence over emotional expression and loneliness sequentially mediates the relationship between parentification and smartphone dependency. The participants were 311 upper-elementary school students (4th to 6th graders; 126 boys, 40.5%) in doubleincome households residing in Seoul, Gyeong-gi, and Incheon. The data were collected through an online self-report questionnaire completed by the participants and were analyzed using SPSS 26.0 and Mplus 8.7 software. The results can be summarized as follows. Firstly, the direct effect of parentification on the smartphone dependency of the children from double-income families was statistically insignificant. Secondly, ambivalence over emotional expression mediated the effect of parentification on smartphone dependency, while loneliness did not. Lastly, parentification influenced smartphone dependency through the sequential mediating channel of ambivalence over emotional expression and loneliness. In conclusion, these findings indicate that interventions for smartphone-overdependent children from double-income families should place emphasis on children's psychological difficulties attributed to parentification. Specifically, this study highlights the importance of alleviating the levels of ambivalence over emotional expression and loneliness to address the issue of children's smartphone dependency in double-income families, suggesting possible involvement and support at both household and societal levels.
