This study aims to identify the impact of the logistics industry on the Korean national economy. To do this, we used a MRIO table provided by the Bank of Korea which includes inter and intra regional relationship of the production and consumption for 6 areas - the Seoul Metropolitan, Gangwon, Chungcheong, Jeonra, Gyeongbuk, Gyeongnam area, but an original MRIO table was recomposed of 29 sectors focused on logistics industry for the purpose of this study. we analyzed producing-inducing effects, supply-shortage effects and inter-industry linkage effects based on logistics industry by region and industry. As a result, the logistics industry has more supply-shortage effect rather than production-inducing effect and has a higher ripple effect on the automotive in Gyeongnam area and petrochemical industry in Jeonra area. In particular, the ripple effect of th Metropolitan logistic industry was far smaller than that of other areas, because the Seoul Metropolitan industry was identified as the primary and middle demand industry.

In this study, the concentration and distribution characteristics of BTEX (benzene toluene, ethylbenzene, and xylene) emitted from Daesan Petrochemical Industrial Complex were examined to determine their potential hazards to local residents. Residents living nearby the complex areas may be exposed to the chemicals through various media (air, water, and soil), especially by air. This study evaluated human health risks by inhalation using both deterministic and probabilistic risk assessment approaches. As a result of the deterministic risk assessment, the non-cancer risk was much lower than the regulation limit of hazard index (HI 1.0) for all the points. However, in case of cancer risk evaluation, it was found that the risk of excess cancer for benzene at point A located in the industrial complex was 2.28×10^-6, which slightly exceeded the standard regulatory limit of 1.0×10^-6. In addition, the probabilistic risk assessment revealed that the percentile exceeding the standard of 1.0×10^-6was found to be 45.3%. The sensitivity analysis showed that exposure time (ET) had the greatest impact on the results. Based on the risk assessment study, it implied that ethylbenzene, toluene, and xylene had little adverse effects on potential human exposure, but benzene often exceeded the cancer risk standard (1.0×10^-6). Further studies on extensive VOCs monitoring are needed to evaluate the potential risks of industrial complex areas.

Recently, the safety of chemical substances has gained attention due to incidents occurring in petrochemical industrial complexes, such as gas leaks and fires. In particular, industrial complexes in Ulsan and Yeosu (South Korea) are valuable as they significantly contribute to the petrochemical industry, but accidents may occur due to chemical leakage. Therefore, in this study, sensor nodes are configured at an interval of 20 [m] based on outdoor facilities standards to respond to chemical accidents, and exposure consideration of 8 h (TWA) and 15 min (STEL) are proposed in TLVs. The proposed system pre-processes data collected in multi-hop communication at a cycle of 0.6-0.75 [s] using Python and stores it in the MySQL database through SQL and a real-time remote monitoring system that updates the stored data once every 5 s is implemented by linking MySQL and Grafana.

The purpose of this study is to check the priority control status of the current operation process alarm by comparing the priority of the alarm set up in PV high trip point, which is being installed and operated in the domestic petrochemical industry, with the criteria presented in ISA 18.2 International Standard or EEMUA 191 Guidelines. In the event of a process problem, excessively set high alarm is provided to the driver in a short period of time, making it difficult to identify the alarm that needs to be handled first. As a result, it is likely that the operator will not be able to carry out appropriate actions within the specified time frame, and many cases have been reported leading to unexpected process shutdowns or process accidents. Therefore, this study aims to introduce international standards related to alarm management and identify the level of alarm control used at the domestic petrochemical industry site to inform potential risks that may occur in the petrochemical process of the national industrial complex in the future and suggest ways to reduce risk factors. This paper was submitted to Professor Lee Inbeom's retirement anniversary issue.

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.

중화학 및 정유산업은 1960년대 우리나라의 초기 경제개발 당시 핵심산업 중의 하나였으며, 최근 국내의 유류소비 상승과 석유화학분야 고부가가치 생산기술의 확보 등으로 설비의 중요성이 증대되고 있다. 이와 같은 이유로 관련업계에서는 중단 없는 설비운전이 요구되는 경우가 많아지고 있으며, 현재 많은 경우에 과부하 상태에서 운전되고 있다. 그러나, 국내의 관련 설비들은 거의 70년대에 제작되어 설비 노화가 상당히 진행되어 있으며, 따라서 연속가동에 의한 설비의 대형 파손사고의 위험성도 높아지고 있다. (중략)

D-Gun과 plasma 코팅이라고 하는 코팅(도금) 기술은 1950년대 미국 유니온 카바이드사에 의해 세계 최초로 개발되어 실용화된 이래 전세계의 산업전반에 걸쳐 꾸준히 그 응용분야가 확대되어 왔으며, 오늘날에는 점보 제트 여객기의 엔진으로부터 석유화학설비, 제철제강설비, 섬유기계, 인쇄기계, 제지기계, 식품기계, 발전설비, 자동화부품, 전자제품 등에 이르기까지 각종 산업기계 및 제품 생산에 응용되고 있다. 특히 최근에는 이들 산업기계가 고속화, 고성능화, 고품질화됨에 따라 그 구성부품도 필연적으로 고성능의 내구성 등이 요구되어 세라믹 등 특수 코팅의 필요성이 절실히 요구되고 있다.

본 논문에서는 산업연관 분석모형을 이용하여 1980년대 수출산업에서의 유가변화의 산업별 파급효과를 분석하고, 1990년대 유가 파급효과를 추정하여 보았으며, 1980년대 산업별 물가상승 요인을 계측하여 1970년대 물가상승요인과 비교분석하여 보았다. 1980년대 상반기의 유가 파급효과가 큰 산업은 석유제품과 에너지 다소비 품종인 화학, 비금속 광물, 전기가스수도, 철강, 금속 등으로 나타났으며 대부분의 산업은 유가인상율의 5% 내외의 인상효과를 나타내었다. 유가 인하기였던 1980년대 하반기에도 인하효과는 산업별로 상반기와 비교할 때 큰 차이는 없었으나, 기계, 전기, 전자통신, 자동차 등 주요 수출산업의 가격인하 효과는 그다지 크지 않은 것으로 분석되었다. 저물가 시대였던 1980년대의 주요 물가변화 요인으로는 임금 등 부가가치 및 원유가격의 변화로서 1970년대와 큰 차이가 없었으나, 중간재 수입가격, 수입계수 및 수업률 변화의 물가변화 기여도는 아주 작아서 1970년대와는 다른 양상을 보였다. 한편 1990년대의 유가파급효과 추정을 위한 모의실험 결과를 보면, 1980년대와 마찬가지로 석유관련 제품의 가격인상 효과가 두드러지겠지만, 1970년대와 1980년대에 비해서 유가파급효과는 상대적으로 낮을 것으로 추정되어 수출산업의 가격경쟁력은 임금, 기타 원자재 가격 등 여타 물가인상 요인에 더 영향을 받을 것으로 예상된다.
